TECHNICAL AREA

The invention relates to a machine with the rod-shaped foods such as chop sticks and the like Have the material to be sliced. such Cutting machines can be found in butcher shops, grocery stores and corresponding food manufacturing and Packaging facilities are operated.

STATE OF THE ART

Cutting machines of the type mentioned are known. Your cutting devices consist of a rotating one Single or double knife. The respective cutting material is the Cutting knife within a receptacle that is more open than the top Channel can be formed, supplied. Feeding the respective material to be cut, such as for example the chop stick is divided by means of a slider, the material to be cut gradually, corresponding to that resulting from the individual slice cutting process resulting cycle sequence, the cutting knife supplies. The respective slice thickness can vary of the respective material to be cut or individually desired slice thickness set on a control panel become.

PRESENTATION OF THE INVENTION

The invention is based on this prior art based on the task of improving performance Specify cutting machine of the type mentioned.

This invention is characterized by the features of the main claim given. Useful developments of the invention are Subject of following this claim further claims.

The invention includes that the slide device, by means of the one to be cut or cut rod-shaped food supplied to the cutting device not just one, as in the prior art, but has several sliders. These sliders are so in the room proceed that there is no mutual collision of these sliders can occur. This is an increase in performance Cutting machine possible. So far, during the time in the one slide empty into its rear starting position was moved back on the recording, no food in the cutting device can be cut into slices. Now it is possible that this backward empty run of a slide not in the area of the recording but in there is a spatially separate movement path and that during this backward empty run one Another slide can already be available, a new food of the machine To close the cutting device. This can make it practical continuously rod-shaped foods such as Cutlet sticks fed to the cutting device and by the same are cut into slices.

The slide device has proven to be sufficient to be equipped with only two sliders. Everyone this slider can run in an endless loop path same loop direction, all around.

In the embodiments shown in the drawing the two sliders shown there are each on the same Loop track arranged movably.

So each of the sliders along the inclusion of one rear point to one in the area of the cutting device located front position in the feed direction method. With this feed movement the pushes slider concerned a rod-shaped food like for example a chop stick in the area of Cutter. This and every other slider is additionally in a direction opposite to the feed direction Movable in the opposite direction, the side and / or height is offset to the feed direction. This offset Direction of movement between the feed direction and that Opposite direction is required to be mutual Collision of the slides during their movement in the feed direction and exclude in the opposite direction. The Movement in the opposite direction to the feed direction is part of the backward empty travel of the relevant slide.

As also the embodiment shown in the drawing shows are the feed direction and the Opposite direction in the area of the recording parallel to each other available. That means that in the area of Cutting device of the relevant slide laterally and / or must be traversed in height. The same applies in the area of the respective rear Starting position of the slide. There the slide has to go again from its trajectory defining the opposite direction in its trajectory defining the direction of advance across be moved.

In the present example, the sliders are one Guide device held and guided so that it without mutual collision can be moved back and forth. The Guide device of the respective slide has a Longitudinal guide, along the one carriage in the feed direction and can be moved in the opposite direction. On each carriage is a drive device for the on it attached sled available. In addition there is one Transverse adjustment device present on the slide, by means of the sled in question with respect to the back and forth Movement of the carriage cross direction can be adjusted can. This cross adjustment is in the present Example realized by means of a lifting cylinder that is operated pneumatically in particular. The lifting cylinder can move the sled in a linear motion or adjust crosswise in a swivel movement.

The longitudinal guides for the guide devices are available above and along the recording. By for example double or through one in cross section non-circular, rod-shaped or tubular design the longitudinal guides can be swivel-proof alignment of the Sledge to be ensured.

Each slide that can be moved back and forth along the receptacle is attached to his sled so that it is in linear Movements or swiveling movements can be adjusted transversely can. This ensures that the slider at Do not collide with the carriage movement can. Of course, this must also be excluded be that of a slider on the recording transported rod-shaped food with another Slider could collide. With a Appropriate route control for the sled can be do this easily.

To an orderly, also mutually scaled filing of the slices of food cut one after the other make it possible, at least the axis of rotation the cutting knife at a tilt angle greater than zero degrees and align less than 90 degrees to the horizontal.

Further advantages and features of the invention result by the features further specified in the claims and from the following embodiment.

WAYS OF CARRYING OUT THE INVENTION

A cutting machine 10 (Fig. 1) for cutting bar-shaped foods such as The chopstick 12 has a rotation axis 14 rotating cutting knife 16.

The cutting knife 16 is located on the left with respect to FIG. 1 End of an open-top receptacle 20 on which the cutting chop stick 12 to the cutting knife 16 is pushed shut. One chop stick 12 each moved along the receptacle 20 by means of a slide 24. The slide 24 is with a guide device 22 connected. In the present example, there are two guiding devices 22 and 22.1 available, both in principle are equally trained.

The slide 24 - and the same applies to the slide 24.1 of the guide device 22.1 - is on a carriage 26 or 26.1 attached attached. The carriage 26 is in one to the feed direction 28, with the one Chop stick 12 is pushed towards the cutting knife 16, parallel direction along two parallel, in Cross section of circular rod profiles 30, 32 slidable. In addition, the carriage 26 is in the feed direction Opposite direction 38 slidable. The carriage 26 can be thus along the two rod profiles 30, 32 in both Move directions 28 and 38 back and forth. Regarding the The same applies to other guide device 22.1. So is whose slide 24.1 along two rod profiles 30.1 and 32.1 also back and forth in both directions 28 and 38 forth. The respective two bar profiles 30 and 32 and 30.1, 32.1 are on opposite outer sides of the Recording 20 and in the cutting machine 10 in each other different heights available. The along the two Rod profiles 30, 32 or 30.1, 32.1 movable slide 24, 24.1 are laterally offset to the bar profiles and facing each other so that all sliders are in the same Level 36 can be moved.

The carriage 26 has two guide rollers 40 and 42, respectively from the outside on the rod profile 30 or 32 slip-free. One runs along the two rod profiles 30, 32 Spindle rod 34, on which a nut is screwed, the is connected to the carriage 26. The spindle rod 34 is via a drive belt 44 with a motor drive 46 rotatably connected. Rotation of the spindle rod 34 leads to a corresponding adjustment of the mother and thus the Slide 46 along the spindle rod 34. The motor Drive 46 is carried by the carriage 26.

A pneumatic cylinder 50 is also on the carriage 26 attached that its piston rod 52 in to the feed direction 28 and opposite direction 38 transverse direction 54 or 56 height can be moved back and forth. At the bottom The end of the piston rod 52 is via a holding plate 58 Slider 24 attached.

The same applies to device 22.1. Even there is the slide 24.1 on a pneumatic cylinder 50.1 also in height in the transverse direction 54 or 56 adjustably attached.

The slide 24 can thus by the method of Carriage 26 along the two rod profiles 30, 32 in Feed direction 28 or in the opposite direction 38 method. In addition, the slide can be corresponding pneumatic adjustment of the pneumatic cylinder 50 in the direction of advance 28 and opposite direction 38 Cross direction, d. H. in height towards 54 or 56 method. The same applies to the slide 24.1. In order to can both slider 24, 24.1 directly in the area of Move the holder 20 one after the other in the feed direction 28 be and a chop stick 12 each Feed cutting knife 16.

In the area of the receptacle 20, each slide moves a rear position 60 into a cutting knife 16 upstream front position 62. After reaching the position in the area of the front position 62 the respective Slide 24 by means of the pneumatic cylinder 50 upwards proceed and then in one above the receptacle 20 existing parallel path in the opposite direction 38 backwards move and then again in the transverse direction 54 move down in the area of the receptacle 20. The same applies to the other slide 24.1.

The slide 24 moves in the feed direction when it is moved 28 and in the opposite direction 38 in one vertically aligned plane 36. Moved in the same plane the slide 24.1; only is the respective position of the two slides 24 and 24.1 within this level 36 offset in height to each other.

In the present case, the movement of each slide takes place 24, 24.1 along a parallelogram. The slope Alignment in the area of the transverse direction 54, 56 takes place in the the present case, therefore, in the area of the front Place 62 of the respective slider there in easy adjusted backwards in the upward direction can be. The slider should not be with the Cutting knife 16 casing parts or other Device parts can collide.

In the present example, the cutting machine 10 is on Feed belt 70 assigned transversely. With this feed belt 70 can 72 chop sticks 12 in succession in the feed direction be transported into the area of the receptacle 20. In order to these chop sticks do not collide with the pusher 22 can guess are the two rod profiles 30, 32 of this slide device 22 higher than that opposite two bar profiles 30.1, 32.1 above the receptacle 20 attached (Fig. 3). So are the two Bar profiles 30, 32 at a distance of 80 and the other two Bar profiles 30.1, 32.1 in contrast, much smaller Distance 82 above the receptacle 20 and thus also the Feed belt 70 arranged. To the same pneumatic cylinder 50 and use 50.1 for both devices 22, 22.1 can, is the pneumatic cylinder belonging to the slide 26.1 50.1 via a correspondingly projecting upward Scaffold 76 relative to the slide 26.1 higher on the same attached when the pneumatic cylinder 50 on the slide 26 is.

Via a path-controlled control of the motor drives 46 and 46.1 for the two sledges 26 and 26.1 and the control of the two pneumatic cylinders 50 and 50.1 prevents the slide 24 and 24.1 can collide with each other or with chop sticks 12.

The feed belt 70 could also be an extension of the form shaft-shaped receptacle 20, so that then Feed direction of the feed belt 70 of the feed direction 28 would correspond.

The cutting machine 10.4 shown in FIG. 4 corresponds in principle the cutting machine described above 10. It also has several sliders 24.4, which without mutual collision when transporting one Cutlet 12 through a cutting knife 16 in Space can be moved back and forth. However, in In contrast to Fig. 1, the axis of rotation 14.4 Horizontal H tilted at a tilt angle 84 so that the Cutlet 12 from the respective slide 24.4 on the sloping receptacle 20 against the cutting knife 16 can be pushed. This makes them fall on the Cutting knife 16 cut slices 13 better organized on a tray 18, for example, one on top of the other than with the cutting machine 10 is the case. In the present For example, the tilt angle 84 of the axis of rotation 14.4 manufactured by having the entire machine around this Tilt angle 84 is arranged obliquely in the room, as well as in Fig. 4 is shown in principle.

Of the cutting machine 10.4 is only a guide device 22.4 shown with a slide 24.4. The Slider 24.4 is drawn solid in a position in which he has a chop stick 12 against the cutting knife 16 pushes. The slide 24.4 is shown in dash-dot lines in a swiveled up position in which he is in the Opposite direction 38 again in its - in Fig. 4 - right Starting position is retracted. When pushing the chopstick 12 moves the slider 24.4 in the Feed direction 28. The slide 24.4 is along the Guide device 22.4, which consists of a rectangular, hollow Rod profile 30.4 is in the feed direction 28 and in the for this purpose, opposite direction 38 adjustable, and in principle with the two slides 24, 24.1 of the cutting machine 10 is described.

At the same height, parallel at a distance next to the guide device 22.4 is a second guide device present on which at least one more Slide, which corresponds in principle to slide 24.4, can be moved along the existing bar profile. The two guiding devices and thus the two Bar profiles are arranged in parallel one behind the other, so they are in Fig. 4, which is a side view of the machine represents falling into each other. For the sake of clarity is that on the invisible guide device movable slide with its carriage not shown.

The slide 24.4 has one by means of a pneumatic cylinder 50.4 movable claw 86. With the claw 86 leaves the rear end of a chop stick 12 pressure and detect tensile strength, as well as that shown in Fig. 4. in the swung up state, which is indicated by the reference numeral 24.5 is shown, the claw 86.5 is pivoted back in the Slider housing protected. Slider housing 87 is in a joint 89 by means of a wall-like support 88 pivoted in the plane 36. This joint 89 is on a slide 26.4 formed. The sled 26.4 is along the bar profile 30.4 in the transport direction 28 and in the opposite direction 38 adjustable.

The piston rod 90 of the pneumatic cylinder engages on the carrier 88 50.4 articulated. The line of action 91 of Pneumatic cylinder 50.4 does not go through joint 89 through so that by moving the piston rod in and out 90 the slide housing 87 and thus the slide 24.4 in its two different ones shown in Fig. 4 Swivel positions can be brought. By retracting the Piston rod 90 gets the slide in his dash-dotted position 24.5, while by extending the Piston rod 90 the slide pulled into its drawn position 24.4 arrives. The pneumatic cylinder too 50.4 is attached to the slide 24.4 and is move back and forth with the same.

The two slides on the cutting machine 10.4 are with their valve housings 87 and thus with their respective slide 24.4 also as in the Cutting machine 10 arranged movable. The Slider housing with slides 24.4 move on one level 36, which is shown in Fig. 3, endlessly around each other, wherein the respective "lower" slide through a chop stick 12 the cutting knife 16 pushes through during each "Upper" slide moved back in the opposite direction 38 becomes. The slides 26.4 of the two slides collide not with each other, because the sledges with respect to those by the Recording 20 defined alley in which the respective Pork chop stick 12 is moved, right and left respectively are present on the side, and in principle from FIG. 3 can be seen.

In the cutting machine 10.4, as already stated is, the two rod profiles 30.4 at the same height arranged based on the receptacle 20. However, it would be also possible, the height of the two bar profiles 30.4 to arrange offset, as well as the cutting machine 10 of the Case is. The height of the bar profiles is aligned yourself according to local conditions and also whether the feed belt 70 of the cutting machine 10, which is in principle also present in the cutting machine 10.4, in the longitudinal direction or transversely to the receptacle 20 of the respective Machine is fed.

To avoid frictional forces between the Chopstick 12 and the recording 20 during the Longitudinal displacement of the chopstick 12 by means of the respective Slider, it is possible to record 20 by one to form endless conveyor belt, for example. The conveyor would then move with the movement of the Cutlet bar 12 sliding slide 24.4 synchronously run along.
