Description

 Bowling ball / pin conveyor

The present invention relates to a bowling ball / pin conveyor, which on the one hand feeds the pins that have been cleared from the fairway to a vertical conveyor, which is connected to the pin Aufslelleinrichtung, and the other after the throw ball rolled beyond the end of the fairway feeds the ball return path leading to the players.

Bowling facilities usually include

a fairway on which the pins are also set up, a sliding device that pushes pins left or left on the fairway into a äumbräumgrube, a Λbräumgrube with a mechanism for feeding pins to a conveyor, a device for separating the ball and pins as well as

Returning the game ball to the players, a conveyor device for feeding the pins to an installation

Settling device and the pin-up / selector device.

A pin set-up and set-down device is described in the application PCT / DE94 / 00643. This includes a pin feeder that is from the vertical conveyor feeds coming pins of a positioning device, as well as this positioning device and a sliding device. The positioning device also comprises a gripping device with which pins which have remained after the throw can be lifted off the fairway and, in the same position in which they have remained after the throw, is placed back on the fairway. Furthermore, with the help of an assembly device and a control device, pins that have been cleared from the fairway and fed to the conveying device can be brought into any receptacles of the positioning device, so that the positioning device is able to implement any predetermined pin configurations on the game path or even next to the After the throw, pins that have stopped are put up further pins.

A ball and pin conveyor device is known from the prior art, for example, which has a conveyor belt which is moved on its upper side in the direction of throw and whose moving upper side extends approximately from the end of the fairway to the pin conveyor. A play ball guide is attached above the conveyor belt and runs parallel to the surface of the conveyor belt and at an acute angle to the transverse direction of the play track. Pins that have fallen and cleared from the fairway slide under the ball guide or are conveyed through it by means of the conveyor belt. With the help of this game ball guide in cooperation with the conveyor belt surface running in the direction of throw, the game ball is roped out of the area of the conveyor belt and fed to the game ball return path. At the end of the conveyor belt opposite the end of the fairway there is a ring gear for conveying the pins to a set-up device, the axis of rotation of which runs parallel to the longitudinal direction of the fairway and which has noses arranged along its inner cables in a regular absland. When the pins come to the end of the conveyor belt, they fall into that part of the rotating hollow wheel which is arranged below the upper ropes of the conveyor belt. The pins then lying on the inner cables of the hollow wheel are gripped by the lugs and taken along by them in the direction of rotation of the internal gear. In this way, the pins on the inside of the hollow wheel are conveyed upwards. At a certain point in time, the pins fall from the ring gear or from the lugs from above into a funnel-shaped opening in a channel. This occurs at a certain rotational position of the ring gear, in which the geometry of the nose no longer allows the pins to remain stable. The geometry of the channel favors that the pins fall with their plain part or their foot forward into the channel and are fed from there to a opening mechanism.

A disadvantage of this described ball and pin conveyor device is that the pins do not always fall into the channel in the same direction. Therefore, it happens from time to time that a pin gets stuck in a receptacle of the ufuflelleinrichtung. It is then necessary to stop the entire system and to check for the existing fault. The wrong pin must then be inserted manually in the required manner into the corresponding receptacle.

Another disadvantage of this ball and pin conveyor is that it is very complex, i.e. is built with a large number of moving components. This requires a relatively large amount of effort for setting and maintaining the system. In addition, the error rate of the system increases, so that a relatively high repair effort is required.

In addition, a pin conveyor is known, which is designed as a vertical conveyor with horizontal entrainment and is also seen from the Sμύelbahn to the conveyor belt. These carriers are movably attached to a rotating chain of the vertical conveyor. At the free end of the vertical conveyor, ie at the discharge height, each driver is pivoted by a cam, so that each pin held by the driver rolls out. Since the pins in this vertical conveyor roll out in an uncontrolled orientation, a mechanism is still required that everyone from the Rolled out vertical conveyor pin oriented in a predetermined manner and fed to the Posilioniereinrichtung via a conveyor mechanism. A disadvantage of this system is, inter alia, that an additional mechanism is required in order to orient the pins coming from the vertical conveyor in a predetermined manner. This additional mechanism is still susceptible to errors, with the entire system having to be switched off in the event of an error and manual intervention being required.

The object of the invention is therefore to provide a bowling ball and pin conveyor device which has the smallest possible height and is constructed as simply as possible, so that it can be produced simply and inexpensively.

It is also an object of the invention to provide a device which ensures that the game ball is separated from the pins as quickly as possible and brings the game ball into the game ball return path as quickly as possible.

Furthermore, it is an object of the invention that the ball and pin conveying device ensures a trouble-free conveying mechanism for the ball and the pins, i.e. that the ball and all pins cleared from the fairway are fed to the ball return or the vertical conveyor at any point and in any position or position in a defined manner, with possible collisions or traffic jams also having to be taken into account and resolved as quickly as possible.

Another object of the invention is to provide a bowling ball and pin conveyor device which itself works as free of interference as possible.

These tasks are solved with the characterizing part of the main claim (s). Alternative versions are described in the associated subclaims. The bowling ball and pin conveyor device according to the invention has the advantage that after the throw, the game ball behind the game path is quickly separated from the pins and reaches the game ball return path.

Furthermore, the susceptibility to malfunction of the system is low, since it is ensured that the pins are only conveyed by the vertical conveyor in a predetermined position.

A further advantage of the invention is that it can be easily integrated with a control and monitoring device. This particularly avoids jamming where the entire system has to be stopped in order to fix it manually.

The subject of the invention is described below with reference to the figures. Show it:

Seen from the fairway, with FIGS. 12-17 showing in individual steps how a pin which is fed upside down to the vertical conveyor is turned into the conveying position, Fig. 1 shows a schematic side view of the entire system. The system comprises the ball and pin conveyor 1 according to the invention, a vertical conveyor 3 and a feed device 5. Furthermore, the overall view of FIG. 1 shows pins 13 standing on the fairway 11, which by means of a clearing device 15, which has a slide 16, from the fairway 11 are cleared if they are to be fed to the vertical conveyor 3. 1 shows a positioning device 17 of the system, to which pins 18 are fed by means of a pin distributor 19. The positioning device 17 shows, by way of example, a first receptacle 21 and a second receptacle 22, both of which are arranged in the positioning device 17 such that they can place pins 13 in a desired initial position on the fairway 11. The positioning device 17 furthermore has a gripping device, not shown in FIG. 1, by means of which pins 13 which have remained on the fairway 11 after a throw can be lifted off the fairway 11, by means of pins which have fallen over on the fairway 11 after a throw by means of the fairway 11 to slide the slide 16 into the feed device 5.

The clearing device 15, the positioning device 17 and the conveying device 19 can also be arranged differently in a known manner and can also be designed differently in detail than is shown in FIG. 1. In particular, a device according to the prior art can also be provided for these functions.

Fig. 1 also shows a conveyor plate 31 of the feed device 5, which is seen in the direction of throw towards the fairway 11 and its surface is arranged below the tread of the fairway 11, and to which after the throw the ball 32 and by means of the slide 16 of the Fairway 1 1 cleared pins 33 fall. 1 also shows a first impact damper 35 with a play ball guide 37, which prevents the play ball 32 from being in a predetermined position in the extended longitudinal direction of the play path 11 on the Rolling out conveyor plate 31, the ball guide 37 is also attached for the lateral removal of the ball 32 to be carried out. The game ball guide 37 is preferably fastened at its ends, to be precise on the side walls 52a, 52b arranged laterally of the conveying plate 31. 1 also shows a second impact damper 39 which is arranged between the first impact damper 35 and the fairway 11 above the conveyor plate 31 and which intercepts pins 13 flung away by the throw or the broaching process and drops them onto the conveyor plate 31.

The first 35 and the second impact damper 39 are attached to a supporting element of a scaffold 41, for example in a hanging arrangement, the scaffold 41 supporting and holding both the vertical conveyor 3 and the movable positioning device 17 and also the clearing device 15. Furthermore, the first 35 and the second impact damper 39 comprise a plurality of sandbags arranged in a row.

As a result, pin wear is reduced and dampening of the play ball guide 37 is achieved. The conveyor plate 31 is arranged obliquely in such a way that the ball 32 falling from the fairway 11 onto the conveyor plate 31 in the extended longitudinal direction of the fairway 11 and the pins 33 cleared from the fairway 11 onto the conveyor plate 31 or fallen down from the second impact damper 39 slide towards the vertical conveyor 3. The first impact damper 35 and the second impact damper 39 are arranged in such a way that they each extend down from the support element of the frame 41 to a height above the conveyor plate 31, at which the game ball 32 under the second impact damper 39, but not under the game ball guide 37 can roll through. In contrast, the pins 33 on the conveyor plate 31 can slide under both impact absorbers 35, 39 and the ball guide 37. As FIG. 1 and also FIG. 13 show, a protective element 40 is provided on the conveyor plate 31 at a suitable distance in front of the vertical conveyor 3, which can throw pins from the fairway 11 by a throw directly to the vertical conveyor 3. The protective element 40 also causes the pins to reach the vertical conveyor 3 laterally. This makes it more improbable from the outset that certain accumulation silions occur in front of the vertical conveyor 3, which, however, are also resolved anyway by the belt arrangement described later.

1 also shows a pin 42a, which has slipped under both impact dampers 35, 39 on the conveyor plate 31 and lies on the conveyor plate 31 in front of the vertical conveyor 3. The vertical conveyor 3 has a chain drive 43 with a first 45a and a second 45b revolving celts (only the circumferential celts 45a can be seen in the rope view of FIG. 1), which consists of two pairs of upper impellers 47a, which are arranged one above the other. 47b and lower impellers 48a, 48b is clamped and guided. On the first rotating trowel 45a, a pair of first pin supports 49a are rotatably arranged, evenly distributed over the chain. The same applies to the second circumferential trowel 45b, on which a pair of second pin supports 49b is attached. A pair of pin supports 49a and a pair of pin supports 49b are arranged slightly offset from one another on their respective celts 45a and 45b (FIG. 14). The pin 42a lying in front of the vertical conveyor 3 is received by the respective two pairs of pin supports 49a, 49b of the vertical conveyor 3. Fig. 1 shows how a recorded pin 42b in the vertical conveyor 3 is fed vertically upwards and the pin distributor 19. 1 also shows how the pin 18 located in the pin distributor 19 is then fed to the positioning device 17.

Fig. 2 shows a side view of the main components of the ball and pin conveyor 1 according to the invention and in particular in sch atic manner the design of the conveyor plate 31. The conveyor plate 31 includes in its near Fairway 1 1 part located an oscillating plate 51, which is also shown in Fig. 12 from below, and a belt plate 52, wherein the oscillating plate 51 and the conveyor plate 52 together form an almost uniform surface. The conveyor plate 31 is roped by a first 52a and a second 52b boundary wall, the upper free ends of which protrude in height above the upper side of the belt plate 31, so that they prevent the game ball or the pins from falling off the conveyor plate. The vibrating platter 51 is driven by vibration moles 53 (FIG. 12), the movement of the vibrating motors 53 causing a resulting oscillating movement 54 of the vibrating platen 51, which essentially runs in the direction of the elongated axis of the fairway 11.

The movement of the vibrating platen 51 has the effect that pins 33 falling from the fairway 11 onto the vibrating plate 51 are prevented from moving further in the direction of the vertical conveyor 3 by friction and by small particles or impurities lying on the conveyor platen 31, but rather to the vertical conveyor 3 slide down.

A wall 57 is provided on the end of the conveyor plate 31 facing the vertical conveyor 3. The wall 57 runs along the end (y direction) facing the vertical conveyor 3 from the first boundary wall 52a almost to the side of the corresponding first pin support 49a facing the first boundary wall 52a. The wall 57 runs at a point in the elongated longitudinal direction of the fairway 11 (x position) which corresponds to the position of the free ducks of the first 49a and second 49b pin supports, if the pin supports 49a, 49b are the height of the vertical conveyor 3 have reached the upper edge of the conveyor plate 31. There is also the side of the conveyor platen 31 facing the vertical conveyor 3. The side of the wall 57 facing the vertical conveyor 3 is adjoined at a right angle thereto by a guide wall 101, the broad side of which extends in the direction of the elongated axis of the fairway 1 1 (x- Richlung) runs and with it the Förderplatle 31 Ropes facing away, for example, ends on a scaffold part on the left side of the vertical conveyor 3 as seen from the fairway 11. The guide wall 101 extends almost along the entire height of the vertical conveyor 3. The wall 57 and the guide wall 101 ensure that pins 33 only reach the pin supports 49a, 49b from the right soap as seen from the front or from the fairway 11 can.

In the area from the fairway 11, as seen from the left rear corner of the conveyor plate 31, an angle ph.tle 59 is provided at an angle to the same. This extends along the second boundary wall 52b and from a certain height above the upper edge of the conveyor platen 31 facing the second boundary wall 52b to an area within the conveyor plate 31 just above it. The angle plate 59 prevents pins from being pinched between the second boundary wall 52b and the end of the belt plate 52 facing it. In a corresponding manner, the longitudinal extension of the angle plate 59 begins in front of the belt, the upper side of which moves towards the second boundary wall 52b (FIG. 4).

The device for separating the ball 32 from the pins 33 provided in the feed device 5 will now be described in detail with reference to FIGS. 4 to 7: the ball 32 which has fallen from the fairway 11 onto the conveyor plate 31 after a throw rolls under the second due to its kinetic energy Impact damper 39 and abuts against the ball guide 37 attached to the first impact damper 35, by which it is also prevented from continuing to roll towards the vertical conveyor 3. On the rie enplalle 52 a Spielball conveyor belt 63 is arranged in the area below the Spielballführung 37 and seen from the fairway 11 in front of the Spielballführung 37. The game ball conveyor belt 63 runs parallel to the game ball guide 37, ie transversely to the axis of the fairway 11. The spacing of the game ball conveyor belt 63 from the game ball guide 37 is provided such that when the game ball 32 bears against the game ball guide 37 The point of contact of the game ball 32 on the conveyor plate 31 or on the game ball conveyor belt 63 lies approximately on the center line of the game ball conveyor belt 63.

The play ball conveyor belt 63 is driven by a belt drive motor 69 (FIG. 8). In the figures, the game ball conveyor belt 63 is driven in a direction that its upper side away from the second boundary wall 52b, i.e. runs counter to the y direction defined in FIG. 1. Because the game ball 32, as described, touches the game ball guide 37 in its upper surface area, the game ball 32 is moved towards the first boundary wall 52a of the conveyor plate 31 at slightly less than half the belt speed of the game ball conveyor belt 63 against the y-direction . At the inflection point 72 of the game ball conveyor belt 63, a game ball goal 73 is arranged in the boundary wall 52a. At least one optical sensor 75 and at least one capacitive sensor 11 are attached to the game ball goal 73. The capacitive sensor 11 is located at a point in the game ball goal 73 which lies in the region of the point of contact of a game ball 32 lying on the game ball conveyor belt 63 and on the game ball guide 37 with the game ball goal 73. A bolt with an actuating magnet 79 is attached to the first boundary wall 52a, for example above the game ball goal 73.

The capacitive sensor 11 detects when the game ball 32 is at a relatively short distance in front of the game ball goal 73. A control, not shown, is then used to supply the actuating magnet 79, for example, with current, so that the game ball goal 73 is unlocked. The motion ball of the game ball 32 can then open the game ball goal 73 (FIG. 6, FIG. 7). Through appropriately shaped tracks, the game ball 32 rolls through the game ball goal 73 and then in a game ball return track, not shown, parallel to and along the game track 11 back to the players located at the beginning of the game track 11. The distance of the game ball 32 from the game ball goal 73, at which the capacitive sensor 11 reacts, depends on the hysteresis characteristic of the capacitive sensor 11. A capacitive sensor 77 is therefore selected in the present case, which has the suitable characteristic.

In addition, the capacitive sensor 11 is connected to a controller which causes the ball goal 73 to be unlocked only when the capacitive sensor 11 responds for a predetermined holding time. This reverberation time is preferably approximately half a second. The provision of the hall time has the effect that the capacitive sensor 11 does not respond when a pin 13, for example thrown from the fairway 11, flies past the ball goal 73 and thus past the capacitive sensor 11. Because of this, the provision of a hall time means that the capacitive sensor 11 does not respond even if the game ball 32 hits the game ball goal 73 at a relatively high speed. In this case, since the capacitive sensor 11 does not yet react at the time of the impact, the game ball 32 is elastically pushed away from the game ball goal 73.

Therefore, the capacitive sensor 11 responds only when the game ball 32 bears against the game ball guide 37 for a predetermined period of time and is moved toward the game ball goal 73 due to the movement of the game ball conveyor belt 63. The speed at which the game ball 32 approaches the game ball goal 73 is approximately half the speed of the top of the game ball conveyor belt 63.

At the game ball goal 73 is a return spring attached so that the game ball goal 73 closes automatically when the ball 32 is rolled through it.

The optical sensor 75 is provided for the case in which the game ball is stuck with a pin in front of or in the game ball goal 73. In this case the control unit reverses the direction of rotation of the game ball conveyor belt 63 for a predetermined time, so that the game ball 32 is briefly moved away from the game ball goal 73 and the pin can slip in the direction of the vertical conveyor 3. By again reversing the direction of rotation of the game ball conveyor belt 63, the game ball 32 is again moved in the direction of the game ball goal 73 and can roll through it, provided a second pin does not block the path of the game ball again and a repetition of the described procedure is necessary to release the pin is.

Other types of sensors according to the prior art can also be used in an analogous manner. However, it is also possible to provide only a capacitive sensor 11 or an optical sensor 75 or another type of sensor on the game ball goal 73 if a corresponding control can take into account and resolve the above-mentioned faults. Furthermore, the locations at which the sensors are arranged according to the described embodiment can also be located differently, as long as the basic function of the sensors is fulfilled.

The advantage of using sensors and a control is that the number of moving mechanical parts is reduced. This increases the functional reliability, so that the repair and maintenance work is reduced. In addition, the system is cheaper to manufacture.

As shown in FIGS. 8 to 13, the conveyor plate 31 has, in addition to the play ball conveyor belt 63, a pin conveyor belt 81, a turning belt 83, a drive belt 84 and a pin turning belt 85, each belt 63, 81, 83 , 84, 85 are spanned by two impellers at their turning points. Specifically, the game ball conveyor belt 63 is a first 63a and a second wheel 63b, the pin conveyor belt 81 of a first 81a and a second wheel 81b, the Reversible belt 83 spanned by a first 83a, a second wheel 83b, the drive belt 84 by a first 84a and a second wheel 84b and the pin reversible belt 85 by a first 85a and a second wheel 85b. The wheels 63a and 81a of the belts 63 and 81 located near the first boundary wall 52a are arranged coaxially with one another. The impellers 63b and 81b located near the second boundary wall 52b and the impellers 85b, 84b, 83b are likewise arranged coaxially to one another.

The turn belt 83 and the drive belt 84 are arranged between the game ball conveyor belt 63 and the pin conveyor belt 81 near the second boundary wall 52b, while the pin turn belt 85 is seen from the game ball conveyor belt 63 behind the pin conveyor belt 81 and also close the second boundary wall 52b is arranged.

An interference lever, not shown, can be provided between the side edges of the pin conveyor belt 81 and the pin turning belt 85. This perturbation lever extends along the long side of the pin turning belt 85, ie seen from the fairway, to the right of the fairway 11 facing pin supports 49a, 49b. The shutter lever is mounted below the tops of the pin conveyor belt 81 and the pin reversible belt 85 and protrudes over part of its length beyond the tops of the belts 81, 85. The perturbation lever is actuated by a cam which is arranged on the shaft of the first impeller 85a of the pin turning belt 85. With the rotation of the first impeller 85a, the interference lever is thus moved up and down and thus protrudes briefly at periodic intervals beyond the upper sides of the pin conveyor belt 81 and the pin turning belt 85. As a result, the jamming lever has the effect that congestion situations of pins 42a lying in front of the vertical conveyor 3 are avoided in the beginning, since some pins that get into the range of movement of the sliding lever receive a movement impulse from it and in most cases a part of this impulse to nearby pins surrender. The longitudinal direction of the pin conveyor belt 81, like the longitudinal direction of the toy ball conveyor belt 63, runs parallel to the y-direction, that is to say transversely to the elongated longitudinal axis of the play lane 11. The toy ball conveyor belt 63 is driven directly by the belt drive color 69, which is from seen from the drive conveyor 69 behind the pin conveyor belt 81. The drive shaft 88 of the drive motor is arranged coaxially with the first impellers 81a, 63a. The drive shaft 88 drives the first impeller 63a directly, which, seen from the drive roller 69, lies beyond the impeller 81a, the first impeller 8la in operation moving through the first impeller 63a in the opposite direction to the rotary drive shaft 88 of the belt drive motor 69. Therefore, the drive shaft 88 of the belt drive motor 69 extends through the inner ring of the bearing of the first wheel 81a fastened to the drive shaft 88 to the corresponding first wheel 63a for the turning point of the game ball conveyor belt 63 located on the boundary wall 71 in order to drive it.

The pin conveyor belt 81 runs in the opposite direction to the game ball conveyor 63 arranged parallel to this. Since the game ball conveyor belt 63 is driven directly by the belt drive motor 69 and no further drive coloring is provided for the operation of the belt cover 52, the rotational energy of the second wheel 63b of the game ball conveyor belt 63 is transferred to the second wheel 81b of the pin conveyor belt 81 simultaneous reversal of the direction of rotation of the turning belts 83 and the drive belts 84 with the associated wheels 83a, 83b and 84a, 84b is provided. As already stated above, the impellers 63b, 83b, 84b and 81b located near the second boundary wall 52b are arranged coaxially to one another.

The shaft of the second wheel 63b of the game ball conveyor belt 63 is a continuous shaft 89 which, starting from this first end located on the second wheel 63b, extends parallel to the extended axis of the game path 11 in Direction towards the vertical conveyor 3 initially extends up to the second wheel 83b of the turning belt 83 and is firmly connected to the shaft of this second wheel 83b, so that the shaft 89 drives it and thus the turning belt 83. The continuous shaft 69 protrudes first through the inner ring of the bearing of the second wheel 84b of the drive belt 84 fastened thereon and then through the inner ring of the bearing of the second wheel 81b of the pin conveyor belt 81 which is also fastened thereon. The shaft 89 passing through the through shaft 89 is fixedly connected at its second end to the shaft of the second impeller 85b of the pin turning belt 85.

The Uemen 83 and the drive belt 84, whose longitudinal directions are parallel to each other, angeoi dnel between the Spielball-Föi derriemen 63 and the pin conveyor belt 81, which also extend to the reversible belt 83, the drive belt 84 along the pin conveyor belt 81st runs, that is between the pin conveyor belt 81 and turning belt 83. Viewed from the second boundary wall 52b, both belts 63, 81 extend only over a relatively small part of the width of the belt plate 52, so that their first wheels 83a, 84a are substantially closer to the second boundary wall 52b than to the first boundary wall 52a. However, the turning belt 83 has a greater length than the driving belt 84, so that the first running ad 83a of the turning belt 83 is more distant from the second boundary wall 52b than the first running wheel 84a of the driving belt 84.

The first wheel 84a of the drive belt 84 is arranged coaxially with and next to the third wheel 83c, the axes of which are coupled to one another. The third running wheel 83c lies in the area between the running wheels 83a, 83b, the peripheral surface of the third running wheel 84a of the turning belt 84 being in contact with the outer cables of the turning belt 83 lying below the belt plate 52 and pointing downward (counter to the z direction). Since the drive belt 84 is driven by the third wheel 83c, this coaxially with coupled to the first wheel 84a, the first 84a and thus also the second wheel 84b of the drive belt 84 rotate in the opposite direction with respect to the wheels 83a, 83b of the turning belt 83. Thus, the drive belt 84 also rotates in the reverse direction of rotation as the turning belt 83.

The second wheel 84b of the drive belt 84 is coupled to the second wheel 81b of the pin conveyor belt 81, so that the pin conveyor belt 81 is also driven in the opposite direction to the pin turning belt 85 and thus the ball conveyor belt 63. The reversible belt 85 and the drive belt 84 thus reverse the direction of movement of the ball conveyor belt 63 in the direction of movement of the pin conveyor belt 81 by correspondingly arranging the running wheels 83a, 83b, 83c, 84a, 84b.

Furthermore, the pin turning belt 85 also rotates in the opposite direction to the pin conveyor belt 81, since the second wheel 85b of the pin turning belt 85 is driven directly by the through shaft 89, which drives the second wheel 63b of the ball conveyor belt 63 with the second Impeller 85b of the pin turning belt ^ rotatably connects.

11, 12 show the bearings of the impellers 63a, 63b, 81a, 81b, 83a, 83b, 84a, 84b, 85a, 85b.

FIG. 13 shows the vertical conveyor 3 with the pin supports 49a, 49b, as well as the turning belt 85 and a part of the pin conveyor belt 81 in a top view. The turning belt 85 transports each pin 42a (FIG. 1) to the vertical conveyor 3, which conveys each pin individually with its pin supports 49a, 49b to the pin distributor 19.

The vertical conveyor 3 has a first chain 45a and a second chain 45b, the first chain 45a running parallel to the second chain 45b and are arranged next to each other and parallel to each other when viewed in the y direction. The first chain 45a is located closer to the first boundary wall 52a. First pin supports 49a are arranged in the first circulating chain 45a and second pin supports 45b are rotatably arranged on the respective associated trowel on the second circulating celts 45b. On the one hand, the first pin supports 49a are arranged at a uniform distance on one side of the chain 45a, and on the other hand, in addition to each of these first pin supports 49a, a further first pin support 49a is arranged on the other long side of the first chain 45a. Thus, the first pin pads 49a are rotatably mounted on the first trowel 45a in pairs next to one another and in pairs spaced apart from one another along the longitudinal direction of the chain 45a. Analogously, the second pin supports 49b are attached to the half of the second celt 45b located near the conveyor plate 31 on the second chain 45b. In addition, each pair of second pin supports 49b is arranged slightly above (seen in the z direction) a pair of first pin supports 49a or, viewed in the direction of movement of the celts 45b, in front of the latter (FIG. 14). As a result, each pin is received by a pair of first pin supports 49a and a pair of second pin supports 49b and is conveyed upward in a slightly oblique position relative to the y direction, ie in the z direction (FIG. 15).

The first 45a and the second 45b trowel of the vertical conveyor 3 are arranged at a certain distance from one another and parallel to one another. The distance between the two chains 45a, 45b is on the one hand so small that the pins are received by the two pairs of pin supports 49a and 49b at their lower part 42c, which contains the majority of the pin mass, on the belly of the pin. Thus, the pins 42a fed from the turning belt 85 to the vertical conveyor 3 can only be picked up by a pair of first 49a and second 49b pin supports if the pin 42a in a direction to the pin supports 49a, 49b of the vertical conveyor 3 receiving the pin 42a is moved in which the longitudinal direction of the pin 42a approximately in the y direction extends and the lower part 42c of the pin 42a faces the receiving pin pads 49a, 49b.

On the other hand, the distance between the respective pair of first 49a and second pin supports 49b is large enough that the pin 42b lies stably on the pin supports 49a, 49b during the upward conveyance. This is ensured by the fact that when the pin 42b rests on the pin pads 49a, 49b, the first pair of pin pads 49a holds the pin in the area immediately at the lower end of the pin, and the second pair of pin pads 49b holds the pin in its neck area. Then the center of gravity of the pin 42d is located in the y direction between the pair of first 49a and the pair of second pin supports 49b, so that the position of the pin 49b is stable (see FIG. 15).

Furthermore, the pin 42b has an oblique position relative to the y direction when it is held by the pin supports 49a, 49b, since the pairs of first 49a and second 49b pin supports echoing the pin 42b are arranged offset to one another in the z direction. In order to prevent the pin 42b from sliding off the pin supports 49a, 49b in the y direction, the guide wall 101 which extends in the vertical or z direction is next to and along the side of the first ketle 45a facing the first boundary wall and in a corresponding distance to this and thus to the first pin supports 49a is provided. As already described, the guide wall 101 adjoins the wall 57 at a right angle. The guide wall 101 extends at least from a height which corresponds to the height of the upper outer surface of the turning belt 85 to a region below the upper wheels 47a, 47b of the Celts 45a, 45b. The pin 42b located on the pin supports 49a, 49b touches the guide wall 101 with the point of the uppermost point of the edge line of the pin-unler cables, which point extends furthest against the y-direction. The guide wall 101 thus holds the guide wall 101 open pin 42b in the described oblique position and in particular in the y direction, as long as pin 42b is conveyed upwards. The pin supports 49a and 49b are designed in such a way that their upper side, which faces the pin when the pin 42b is worn, conforms to the shape of the pin 42b over a certain area thereof. This is achieved by a corresponding curvature of the upper sides of the respective pin supports 49a, 49b (FIG. 14, FIG. 15). This prevents, among other things, that the pin 42b can move upward in the direction of the track 11, for example by vibrating movements of the vertical conveyor 3 from the pin supports 49a, 49b.

The pin pads 49a, 49b are rotatably attached to their respective chains 45a, 45b. This can be accomplished by having a corresponding long chain pin 103 over both sides of the corresponding ketle e.g. 45a, is extended and protrudes through a hole in the pivot point of the pin supports 49a arranged on the ropes of the chain 49a. The long chain pin 103 can have a radial extension, a collar or a closure piece 104 at both ends thereof in order to fasten the pin support 49a in the axial direction of the long chain pin 103. The same applies to the pairs of second pin supports 49b rotatably attached to the second chain 45b.

Each pin support 49a, 49b is preferably made in one piece and has a support arm 106 and a guide arm 107. The pivot point of the pin supports 49a, 49b, ie the bore through which the long chain pin 103 projects, is located in the area between the two arms 106, 107. The support arm 106 is much larger than the guide arm 107 and also much longer than this. If the pin support 49a, 49b hangs on the rear part of the chain 45a, 45b as seen from the fairway 11, the longitudinal direction of the support arm 106 is approximately towards the ground and the free end thereof is directed approximately downwards due to the center of gravity thereof. since the center of gravity of the entire pin support lies vertically below the pivot point in the region of the center line of the support arm 106 and in this position of the pin support 49a, 49b. The Guide arms 107 then project with their free ends into the inner area of the respective chain 45a, 45b, that is to say approximately in the x direction.

In operation, the orbital movement of the chains 45a, 45b is counterclockwise as viewed from the first boundary wall 52a. The part of the chain 45a, 45b seen from the fairway 11 thus moves from top to bottom. On the two sides of each lower impeller 48a, 48b of the vertical conveyor 3, a platelet-shaped structure (not shown) is arranged, which extends along the entire height of the vertical conveyor 3. Each plate-shaped structure has a web-shaped deflection guide 111 with a first end 112 and a second end (not shown), wherein the deflection guide 11 1 runs, for example, in the form of a groove along the rope surface of the plate-shaped structure. If the chain 45a, 45b is moved counterclockwise during operation, the pin supports 49a, 49b on the half of the chain 45a, 45b facing away from the conveyor plate are moved from top to bottom. This also happens with the free ends of the guide arms in the inner region of the circulating chain 45a, 45b, as seen from the first boundary wall 52a. A guide element 115, for example in the form of a short pin, is attached to the free end of the guide arm 107, to be precise on the surface which is directed towards the corresponding celts 45a or 45b, and is thus directed towards the region which is from the corresponding Celts 45a or 45b is stretched. The guide element 115 has a length along its axis which corresponds to the depth of the groove of the deflection guide 111. The position of the guide element 115 with the support arm 106 hanging down corresponds approximately in the horizontal, ie in the x-direction, to the position at which the first end 112 of the deflection guide 111, that is to say the entrance thereof, is located. The deflection guides 111 are arranged relative to the position of the guide elements 115 of the pin supports 49a, 49b descending on the chain 45a, 45b such that the guide elements 115 enter the first end by moving the pin supports 49a, 49b downward Retract 112 of the deflection guides 111 and at the Further movement of the pin supports 49a, 49b are guided by the respective deflection guide 111 in their position relative to the chain 45a, 45b.

In the subsequent movement of the pin supports 45a, 49b, they are guided around the corresponding lower impeller 48a, 48b by means of the chain pin 103. The deflection guides 111 run in such a way that, with this movement section of the pin supports 49a, 49b, corresponding guide element 115 guided in the deflection guide 11 1 runs counter to the associated chain 45a, 45b from the most boundary wall 52a or viewed in the y direction counterclockwise is moved there. The pin pad 49a, 49b is thus also rotated counterclockwise. The course of the deflection guide 111, the shape of the pin supports 49a, 49b and the position of the guide element 115 on the corresponding pin support 49a, 49b is provided in such a way that the free end of the support arm 106 of an almost during the described rotary movement position facing the floor during the downward movement after entry of the guide element 115 into the deflection guide 111 is rotated by approximately 90 ° until the guide element 115 has passed the corresponding lower impeller 48a, 48b. After the rotation of the support arms 106, and thus the respective pin support 49a, 49b, the free ends of the support arms 106 protrude approximately in x during the upward movement of the pin supports 49a, 4% or in the receiving position 119 Direction away from pivot point 103 to receive a pin 42b. After this rotation, the guide elements 115 continue to lie in the deflection guide 111. The interaction of the guide elements 115 with the circulation guide 111 prevents the corresponding pin support 49a, 49b from continuing to rotate counterclockwise.

In the further course of the pin supports 49a, 49b upwards, ie in the z direction, they reach the corresponding upper impeller 47a, 47b in the receiving position. At the latest when the long chain pin 103 and thus the pivot point of the respective pin supports 49a, 49b reaches the uppermost point of the chain path has, the pin pads 49a, 49b rotate due to the location of their center of gravity relative to their pivot point 103 from the first boundary wall 52a counterclockwise to the described position of their downward movement. This rotation is further made possible by the fact that the guide element 115 has been released from the deflection guide 111. This rotation is further supported by the fact that the chain 45a, 45b rests on the corresponding upper impeller 47a, 47b at the end of its upward movement and is turned counterclockwise as seen in the y direction, so that the pin also turns. Support 49a, 49b is rotated counterclockwise at this point with the trowel bolt 103 as the fulcrum in the y direction.

Because the support arm 106 of the second pin supports 49b is arranged higher than the support arm 106 of the first pin supports 49a, the inclined position of the pin 42b (FIG. 15) is increased shortly before the pin 42b falls on the pin distributor 19. The second pin pads 49b thus reach the upper impeller 47b shortly before the first pin pads 49a reach their impeller 47a, which is coaxial with the impeller 47b. The second pin supports 49b begin their rotary movement due to the turning movement of their rotating chain 45b on the upper impeller 47b before the first pin supports 49a arranged next to them begin their rotary movement on their impeller 47a. The rotational movement of the second pin supports 49b on the upper impeller 47b thus takes place with a phase feed in relation to the rotational movement of the first pin supports 49a. The inclined position of the pin 42b located on the pin supports 49a, 49b thus increases with the beginning of the described rotational movement of the pin supports 49a, 49b until the pin 42b slips off the pin supports 49a, 49b due to its center of gravity. The end of the pin distributor 19, which faces the vertical conveyor 3, is arranged at a height on the latter so that the pin 42b sliding from a pin support 49a, 49b falls onto the pin distributor 19 in a certain orientation. By means of a guide device, not shown and correspondingly geometrically designed, it is achieved that the pin Pads 49a, 49b fallen pin 18, 42b on the pin distributor 19 with its lower part ahead of the positioning device 17 is supplied.

The rotation of the pin support 49a, 49b starting from the receiving position 119 relative to the chain 45a, 45b can therefore only take place in the clockwise direction seen in the y direction and only when the pivot point 103 of the pin support 49a, 49b is approximately at the apex of the upper impeller 46a, 46b, so that the center of gravity of the pin support 49a, 49b carries out the described relative rotation described.

The lower impellers 48a, 48b and the deflection guide 111 of the vertical conveyor 3 are arranged at such a height that the pin supports 49a, 49b reach the receiving position shortly before the support arms 106 pass the upper outer surface of the turning belt 85. The upper wheels 47a, 47b are arranged at a height such that the pin supports 49a, 49b, which are caused by the application thereof and the turning of the trowel 45a, 45b, start shortly before the pin distributor 19 passes them.

The pin turning belt 85 extends from a small distance from the second boundary wall 52b in the horizontal direction to a point at which the pin supports 49a, 49b closest to the second boundary wall 52b shortly after their rotation into the receiving position 119 on the lower wheels 48a , 48b go up. The pins 42a fed by the pin turning belt 85 in the direction of the pin supports 49a, 49b can thus be received by the pin supports 49a, 49b! when the bulbous portion 42a of the pin 42a is moved toward the pin supports 49a, 49b (FIG. 15).

In the vertical conveyor 3 is on the I lohe of the pin turning belt 85 and seen from the fairway 11 behind it, and at a height that is less than the diameter of the lower part of a pin, a first optical Sensor 131 arranged. Furthermore, a second optical sensor 133 is arranged at a certain distance from a few pin diameters above the first optical sensor 131. Both sensors 131, 133 determine whether a pin 42a has been in the area of the pin reversible belt 85 in front of the pin supports 49a, 49b for a long time without being conveyed away by them or being moved away from the pin reversible belt 85.

Interaction of sensors 131, 133 via a control device is preferably provided. The interaction can take place in such a way that the control device diagnoses a traffic jam situation if the lower sensor 131 sees a pin for a pre-glued line, but the upper sensor 133 does not see a pin driving past in the pre-glued time.

In a traffic jam situation, the control device then causes, for example, the belt drive motor 69 to rotate in the opposite direction and thus the pin conveyor belt 81 and the pin turning belt 85 to be moved in the opposite direction. As a result, the pins located on these belts 81, 85 are brought into a different relative position to one another, and the congestion situation is released. The period of time for which the belt drive motor 69 is operated in the opposite direction is a predetermined time after which, according to experience, conceivable traffic jam situations are reliably resolved.

The position of the sensors 131, 133 can also be provided differently than has been described. For example, the upper sensor 133 can also be arranged within the vertical conveyor 3 and, seen from the fairway 11, between the first 49a and 49b pin supports.

Different types, for example mechanical sensors, can also be used. However, mechanical sensors have the disadvantage that they can be adjusted mechanically and are also more susceptible to faults than optical sensors. On the side of the guide wall 101 facing the first boundary wall 52a, a lever 135 is rotatably mounted, which unfavorably places the pink (on the left pin in FIG. 15) the pin supports 49a, 49b on one of the pin supports 49a, 49b Conveyor belt bumps. The lower part of the lever 135 is formed by an angled section, the tip of which, in the basic position of the live ice 135, protrudes somewhat in the area beyond the guide wall 101 in which the pin pads 49a are located. The upper part of the lever 135 also projects in this area. The lever is designed in such a way that pins which are not in the desired position on the upward-moving pin supports 49a, 49b first at the tip of the lower angled one Push part of lever 135. On the one hand, this gives the pin an I pulse, which normally pushes it away from the pin pads 49a, 49b. On the other hand, the lever 135 rotates itself due to the pulse (clockwise in FIG. 15), so that the upper part of the lever 135 continues to turn toward the passing pin supports 49a, 49b. If the pin is still on the pin supports 49a, 49b, it will be pushed by the upper part of the lever 135 at the latest from the pin supports 49a, 49b.

The mode of operation of the ball and pin conveyor 1 is described below:

After a throw, the game ball 32 and the pins 33 fall from the game track 11 onto the conveyor plate 31. As already described, the game ball 32 is prevented by the game ball guide 37 from rolling over the game ball conveyor belt 63, which runs transversely to the extended track axis. In operation, the upper part of the game ball conveyor belt 63 moves from the second boundary wall 52b to the first boundary wall 52a, ie against the y axis (see FIG. 4). In most cases, the game ball 32 will reach the game ball conveyor belt 63 faster than the pins 33 due to its kinetic energy and its spherical shape. In this case, the game ball 32 on the moving game ball conveyor belt 63 becomes the first boundary wall 32a, and thus without the interference by pins 33 also lying on the game ball conveyor belt 63 promoted to Spiellorlor 73. On the basis of the message from the capacitive sensor 11 in cooperation with the control device on the game ball goal 73, the latch with actuation magnet 79, which is also attached to the game ball goal 73, is opened when the game ball 32 lies in front of the game ball goal 73 long enough. Because of its impulse, which is communicated to the ball 32 at least by the movement of the ball conveyor belt 63, the ball 32 pushes the ball goal 73 and subsequently rolls through it. The game ball 32 is brought into the return path by means of a corresponding drive device or by means of a corresponding geometric shape of the track section (not shown) beyond the first boundary wall 52a. The game ball 32 thus rolls back the track 11 against the direction of throw as soon as possible after the throw. The game ball goal 73 closes automatically due to its spring arrangement. The same player who had thrown the game ball 32 can thus use the same game ball 32 for his next throw after a short time.

In the event that pins 33, for example due to the throwing energy of the game ball 32, reach the game ball conveyor belt 63 just as quickly and block the path of the game ball 32 to the first boundary wall 52a, the optical sensor 75 and a corresponding control device (not shown) provided that recognize that both a pin 33 and the ball 32 in front of the ball goal 73 are at least a predetermined time in front of the same. In this case, a capacitive sensor 11 provided approximately in the middle of the ball ball 73 does not give a positive detection signal to the control device, since a sensor with a hysteresis characteristic is selected, in which the sensor does not respond when between the ball 32 and the ball Ball 73 a pin 33 is located.

In such a case, the control device reverses the direction of rotation of the game ball conveyor belt 63. As a result, the game ball 32 is moved back a certain distance to the second boundary wall 52b. The one before Pin 33 clamped between the game ball 32 and the first boundary wall 52a is released from its jamming and then slips the conveyor plate 31 in the direction of the extended axis of the game path 11, whereby the pin 33 clears the path of the game ball 32 to the game ball goal 73. The game ball 32 then rolls through the game ball goal 73 as described.

Pins 33 that have fallen from the fairway 11 onto the conveyor plate 31 also slide with the help of the vibratory movements of the oscillating plate 51 and due to the inclination of the conveyor plate 31 toward the vertical conveyor 3 from the end of the fairway 11 towards the ball conveyor belt 63. The ball conveyor belts 63 Pins 33 that are reached are normally moved in the negative y direction to the first boundary wall 52a as soon as they lie on the game ball conveyor belt 63. Due to the inclination of the conveyor plate 31 and since both the first 35 and the second 39 impact damper and the ball guide 37 are mounted at a height such that pins 33 can slide under them, the pins 33 slip off the ball conveyor belt after a relatively short time 63 further to the pin conveyor belt 81. The pin conveyor belt 81 moves in the opposite direction in comparison to the game ball conveyor belt 63. Thus, if the pins 33 have slipped onto the pin conveyor belt 81, they will be moved from the place where they came onto the pin conveyor belt 81 towards the second boundary wall 52b. The wall 57 prevents the pins 33 which have reached the pin conveyor belt 81 from slipping further towards the vertical conveyor 3 due to the inclination of the conveyor plate 31.

The pins 42a lying on the pin conveyor belt 81 can only continue to slide in the extended axis of the fairway when they reach the pin turn iemen 85. Depending on the location where the pins 33 fall from the fairway 11 onto the conveyor plate 31, there are also cases in which pins 33 slide in front of the swing plate 51 onto the ball conveyor belt 63 and from there onto the pin conveyor belt 81, and are not first moved along the wall 57, but immediately slide on the pin reversible belt 85. This will be the case if the pins fall from the fairway 11 onto the conveyor plate 31 near the second boundary wall 52b.

The protective element 40 in front of the vertical conveyor 3 causes the pins 42a sliding towards the vertical conveyor 3 to be somewhat distributed in the vicinity of the vertical conveyor 3. As a result, the accumulation silage that arises in the approach is already dissolved at a distance in front of the vertical conveyor 3.

The pins 42a that have reached the pin turning belt 85 are moved away from the second boundary wall 52b and towards the vertical conveyor 3. If the respective pin 42a is aligned in such a way that the lower part of the pin 42a is moved towards the vertical conveyor 3, it is in most cases taken up by the pin supports 49a, 49b: the pin 42a is held by the pin turning belt 85 moves to the vertical conveyor 3, and the pin finally passes beyond the turning point of the pin turning belt 85 located on the vertical conveyor 3. As described, the lower impellers 48a, 48b of the vertical conveyor 3 are arranged at a height such that the pin supports 49a, 49b from below on the end of the conveyor platen 31 facing the vertical conveyor 3 and damil from below on the pin supports 48a , 49b move past the turning point of the pin turning belt 85. At these ends, the pin supports 49a, 49b are already in the receiving position. The pins 42a which are moved beyond the turning point of the pin turning belt 85 are thus taken up by the pin supports 49a, 49b at their lower part 42c. As shown above, this is a stable position for the received pins 42b.

Pins 42a, on the other hand, which are moved on the pin turning belt 85 with their upper part 42d ahead to the upwardly moving pin supports 48a, 49b, are turned in the manner described in FIGS. 16-21, so that they ultimately also get the lower part of the pin pads 49a, 49b ahead (Fig. 21). During this turning process, the upper part 42d of the pin 42b is first gripped by the pin supports 49a, 49b which move upwards. This is however, an unstable position since the center of gravity of the detected pin 42b is outside the plane spanned by the respective pairs of pin supports 49a, 49b (FIG. 16). The pin supports 49a, 49b moving upward give the detected pin 42b an angular momentum (FIG. 17). The detected pin 42b is thus rotated counter-clockwise to the x-axis, ie viewed from the fairway 11 (FIGS. 17-20). Due to the angular momentum, the pin 42b finally arrives in the desired direction, ie with its lower part 42c ahead, on two corresponding pairs of pin pads 49a, 49b which move past the pin turning belt 85 from below (FIG. 21). The pin 42b then has the stable position described on the corresponding pairs of pin supports 49a, 49b (FIG. 15).

In the event that the pin 42b is not immediately turned into the desired position, or that, for example, there is a jam of pins 42a on the turning belt 85 and in front of the vertical conveyor 3, so that the pins 42a do not move somewhat uniformly from the vertical conveyor for a certain time 3 are detected and conveyed upwards, the sensors 131, 133 are provided with a corresponding control device (not shown in the figures). The optical sensors 131, 133 with the control device determine this slau or a longer stay of a pin 42b in front of the vertical conveyor 3. In this case, the pin turning belt 85, and thus also the pin conveyor belt 81, is moved in the opposite direction. The pins 42a are therefore essentially moved back a little the way they came. As a result, the positions of the pins located in front of the vertical conveyor 3 change relative to one another. After a short time, the pin reversing belt 85 and the pin conveyor belt 81 are reversed again. The pins 42a located in the area of the vertical conveyor 3 are then moved in a different relative position to the vertical conveyor 3. However, the congestion situation has been resolved by the movement of the belts 81, 85 in the opposite direction, so that the pins 42a lying in front of the vertical conveyor 3 are then taken up smoothly. Some alternative embodiments of the ball and pin conveyor device according to the invention are described below:

The frame 41 can be designed differently. In particular, this must be adapted to the structural conditions.

The ersle 35 and the second impact damper 39, together with the play ball guide 37, can also be designed differently. For example, the impact dampers 35, 39 need not be arranged in a hanging manner, but they can also be designed as a slab plate, which can also be attached to a frame 41.

Instead of a chain drive 43 with the rotating chains 45a, 45b, the vertical conveyor can have a toothed belt drive with corresponding toothed belts.

The deflection line 111 can also be located only in the area of the lower impeller 48a, 48b, the guide element 111 of the pin supports 49a, 49b resting on the chain after leaving the deflection guide 111 and being held by the chain in its receiving position.
