Description

This invention relates to a machine for packaging confectionery. BACKGROUND OF THE INVENTION There are known devices for stacking boxes of pieces, for example, sweets, containing a gripping head with vacuum suction devices for items, a feeder, a hopper with channels and a mechanism for feeding empty and discharging filled boxes. However, these devices are not very useful, as it happens that an incomplete set of objects, or objects that are not occupied by a certain item, cannot be captured. In the proposed device, the accumulator is made in the form of a table that is fixedly movable, with horizontal slits in each channel and vertical plastines installed movably in the slits in the horizontal direction and serving to fix objects in the channels, and a fixed horizontal platform is placed between the feeder and the accumulator with channels for objects and lifting clamps above it. The accumulator is equipped with spring-loaded probes for objects, rotatable around a horizontal axis and installed on the front side of the channels of the table, as well as a lever system that interacts with the comb. probe for boxes interacting with a comb. This embodiment of the device increases its reliability. FIG. 1-4 schematically shows the proposed device; in fig. 5 — mechanism for feeding empty and withdrawing filled boxes; in fig. b - drive, top view and section. The proposed device comprises a gripping head / with vacuum pumps 2, a feeder 3, a storage device 4, a horizontal fixed platform 5, a mechanism 6 for supplying empty and withdrawing filled boxes and driving with a lever-cam system. The gripping head / has a hinged-lever mechanism 7, on the axis 8 of which the tubes 9 are connected with chalk-food, ending at the bottom with elastic suction cups 2. The mechanism 7 is attached on both sides by means of the axes 10 to the rods //. On the columns 12 melds there are springs 13 with the rods. The rods, through the balls 14, rest on the copiers 15 mounted on the frame. The stock is reinforced in the cheeks 16, which, with their bosses, sit at the ends of the levers 17. The cheeks 16 are hinged 18 by means of the tipper 18 to the L-shaped thrust 19, which, together with the levers 17, sits on the axis 20, and is hinged to the lever 21 The axis 20 is reinforced in the pins of the two levers 22, one of which

the spring 23 is pressed to the lacquer 24. On the axis 25, together with the lever 22, an L-shaped lever 26 is located, pressed by the spring 27 to the fist 28. The lever 26 is pivotally connected to one of the levers 17 by means of the pull rod 29. The axis 20 is fixedly connected levers 17 and is in pivotally connected with lever 22 and tension 19.

A vacuum distribution manifold 30 is attached to the cheeks 16, from which the flexible tubes 31 connect the vacuum to the tubes 9. At the collector there is a plug valve 32 controlled by the fixed stops 33 and 34. A vacuum is supplied to the crane by the flexible hose 35.

The feeder 3 for supplying items is a belt conveyor having channels for each row of items covered on top with transparent covers 36.

The mechanism 6 for feeding empty and discharging the filled boxes consists of a chain conveyor 37 with pushers 38 and guides 39 for the boxes.

The drive 4 is made in the form of a movable table 40 having channels for objects. A horizontal slot is made in each channel of the table into which vertical elastic plates 41 are inserted. Plates 41 are fixed on the tabs 42 when (using spacer sleeves 43, thereby forming a block of tappets. The length of the sleeves 43 is equal to the cross section channel.ov of the table 40. On the horn 42} springs 44 are mounted, pressing the pusher block by means of a rod 45 to the pusher 46 of the lever 47. Rolling pin 42 with its ends is placed in racks 48 and receives a reciprocating movement from the cam 49 through the lever 47, which is pressed against the cam 49 by the spring 50. The racks are attached tolevers 51 which are pressed against the fist 53 by the spring 52.

The platform 5 with channels for objects is located between the feeder 3 and the storage device 4 and is equipped with lifting and lowering clamps 54 located thereon, controlled through the system (by levers (not shown in the drawing) by the fist 55).

To control the presence of objects on the table 40, there are probes 56, L-shaped levers 57, each of which is placed under the corresponding probe 56, U-shaped levers 55 and a comb 59 fixed on the rod 60.

The control of the presence of empty boxes on the conveyor 37 is carried out by means of a lever 61 with a pusher 62 resting on a flat spring 63. For pressing lever 61 serves spring 64.

Probes 56 are reinforced under the movable table 40 so that their upper ends are in the channels of the table and are stops for incoming items, and the lower ends are placed above the horizontal arms of the levers 57. Each probe ends in its lower part with a needle 65 cut along the diametral plane and facing this plane towards the lever 57, as well as with the platform 66. The horizontal shoulder of each lever 57 terminates in a wedge 67, the bevel of which is a continuation of the bevel 65 of the needle, as well as the protrusion 68. The vertical arms of the levers 57 are placed between the teeth Child 59.

In the absence of an object in the channel of the table 40, the probe 56 is turned counterclockwise by the spring 69 until it stops at the table 40. The supports 70 fixed under the table restrict the movement of the probes clockwise. The springs 71 turn the levers 57 clockwise.

The rod 60 is spring-loaded 72 against the fist 73. The fist 74 and the spring 75 are designed to control the lever 55. The end of the rod 60 is the stop for the key 76 of the single-turn key coupling.

Through the sprocket 77 from the drive of the machine, continuous rotation is communicated to the shaft 75, from which a single-turn clutch and a pair of gear wheels 79 communicate periodic rotation to the shaft 80.

Ra; bots device as follows.

iB in initial position, the clamps 54 are raised, the vacuum suckers 2 are above the table 40, and the probes 56 are rotated counterclockwise against the table 40.

Objects continuously moving the conveyor belt push on the receiving table 40 until it stops at the probes 56. At the same time, the pressure of objects overcomes the forces of the springs 69, and w, ups 56 are rotated clockwise to the stops 70. The lever 55 under the action of the springs 72 and the cam 74 performs a cyclic swing motion. When it moves counterclockwise, the levers 57, pressing the lower part of their vertical shoulder to the horizontal crossbar of the lever 58, rotate clockwise and exit from the gaps between the teeth of the comb 59, while the protrusions 65 of the levers 57 freely pass by the pads 66 Probes 56. In the absence of 40 items in any of the channels of the table, the corresponding probe 56 remains in the initial position, and the lever 57, turning clockwise, rests the protrusion 68 into the probe platform 62 and does not extend the vert the root of the shoulder from the gap between the teeth of the comb 55.

If the lredo: met in the channel of the table did not reach its extreme position, then the wedge 67 of the lever 57 meets the bevel 65 with its bevel and, due to the bevel of the latter, rotates the probe to the position corresponding to the absence of the object in the channel.

When there is a box at the position preceding the laying position, it pushes the lever 61 clockwise through the flat spring 63 and the pusher 62, and the lower part of the lever leaves the gap between the teeth of the comb 59.

In this case, if all the levers 57 and the lever 61 are out of the gaps between the teeth of the comb 59, the latter, together with the rod 60, moves to the left and the end of the rod 60 leaves the rotary key 76 of the single turn coupling, which moves through a pair of gears 79 continuously vrash, shaft 78 shaft 80.

Further operation of the device occurs in the following sequence.

First, clamps 54 are lowered, each of which presses the object in its channel against a fixed plate, heel 5. Then elastic plates 41, which were previously mounted in the vertical walls of the channels of table 40, are pushed and pressed against the opposite wall of the channel, the center point is relatively the corresponding vacuum suction cups 2. After this, the suction cups 2 are lowered onto the objects, at the same time the fixed uior 33 turns the plug of the tap 32 and switches on the vacuum. The gripping head / along with the table 40 is moved away from a number of objects pressed by the stops 54 to the fixed platform 5.

Objects trapped by the suction cups are lifted and transferred to the side of the box, with the rods // by the copiers 15 shifted and the transverse pitch between the suction cups is reduced. At the same time, the chain conveyor 37 delivers the box with the napkin lying in it to the laying position.

Table 40 returns to its original position, clamps 54 are raised, and new items are fed onto table 40, and objects captured by head / are lowered into

the box. At the same time, the crane 32 is switched by an unconnected stop 34, the vacuum overlaps and the suction cavity 2 communicates with the atmosphere, the objects remain in the box and the head / returns to its original position.
