Description

The invention relates to a depositing device for a slicing machine, consisting of a Cut goods trolley for placing sausage or the like, a driven knife disc, one from the cut Gutwagen controlled conveyor device for cut goods, for example in the form of parallel, one above the other arranged, spiked chain straps, and one offshoot and one step-by-step movable shelf.

A cutting machine is already known which has an automatic filing system and is used for operation on the counter of a delicatessen store. The cut material is placed on the Schr.ittgutwagen placed, which performs cutting movements against a rotating knife disc. The movement of the Schnitlgutwagens is via a gearbox and freewheels using toothed belts of the conveyor fed, which consists of horizontally running chain belts with spikes and via a Feed roller has. Each cut sheet is now detected by this device and over the middle the tray promoted. In this position, the deposit arm arranged between the chain belts folds or bat forwards in the direction of the tray, thereby releasing the clippings from the conveyor and places it on the tray, on which a stack of parchment paper is conveniently located is located. In addition to setting the slice thickness, it is also possible to switch on the feed of the depository plate. Instead of what is usually stacked, the result is a flaky or fanned arrangement Clippings.

The invention aims to provide a depositing device for a slicing machine that still More options for storing cuttings are permitted and at the same time simple in structure, small in dimensions gen and is easy to use. This is in the case of the depositing device described above is enough that the drive driven by a gear or toothed belt conveyor device through a < electrical impulse switching depending on the position of the car, possibly via a further i Toothed belt drive controllable elekiromagnetischi Coupling or a motor, preferably a pulse-controlled stepper motor, which according to a predeterminedba ren number of revolutions can be switched off, upstream is switched and that the tray by an electro magnetic drive step by step in a Richtuni is movable, with an electronic circuit in front is seen that controls the electromagnetic drive ii depending on the path of the placement arm and that a central keypad is also provided, each key position having a switching interval de electrical pulse circuit for the clutch or the motor and a number of step pulses de

electronic circuit for the electromagnetic Drive corresponds to the storage plate

The pulse circuit, the pulse duration of which can be preselected. causes the clutch to switch on accordingly or the motor. As a result, the conveying device covers conveying paths of different lengths, so that the Cuttings are deposited in different places parallel to the conveyor device and a flake-shaped one Hang up in one direction is possible. If the Filing plate can then be moved by an electromagnetic drive by preselectable step intervals becomes a scaly lay-up in two directions achieved.

According to one embodiment of the invention, the storage plate has a toothing. which in a Ri'zel des electromagnetic stepper drive engages. The electromagnet receives impulses and its iron core moves the pinion and thus the storage plate according to the number of pulses. After another Embodiment of the invention, the tray has a rectangular shape and is in parallel guides of and slidable to the conveyor. It is also advantageous, moreover, for the storage plate to be in the form of a disk train to support their center rotatably, and to be provided with a ring gear, which in the pinion engages. If, in the former case, the result is a sliced cut in two directions, in the latter case, they can be placed directly on a round plate. In each In this case, it is useful if the rectangular storage plate can be exchanged for the disc-shaped storage plate is. This is easy to achieve as both plates are driven by the same pinion and the Feed can be the same.

In the practical implementation of the invention, it is useful if the electrical pulse circuit for Control of the clutch can be regulated and is, for example, a bistable multivibrator circuit. It is in the In practice it is also advantageous to switch the electrical circuit from magnetic switches arranged on a plate at a distance build up and one provided with a permanent magnet, from the movement of the cuttings wagon To be arranged pivotable over the magnetic switches depending on the path driven arm. This facility is simple in construction and problem-free in operation, changes in the interval can be made by moving the magnetic switch can be easily made. The electronic circuit for applying the electromagnetic Drive can be a flip-flop circuit in one embodiment of the invention. Here you can the switching intervals are determined by the charging and discharging of capacitors.

In order to precisely determine the position of the clippings before they are placed on the storage plate, it is a matter of course proved to be advantageous if an electric brake is provided when driving the conveyor device, which can be electrically engaged when the clutch is disengaged. It is therefore ruled out that the The clippings run beyond the desired drop-off point.

It is also useful if, to switch off the motor, a preferably electronic one, the revolutions counting device counting the motor is provided.

Exemplary embodiments of the subject matter of the invention are shown in the drawings.

F i g. 1 shows a schematic representation of a cutting machine using an electromagnetic one Coupling, whereby the storage plates are interchangeable,

F i g. 2 a cutting machine, the conveyor device of which is driven by an electric motor, and F i g. 3 shows the bending arm in side view as a detail

The cut material carriage 1 can be moved back and forth in a guide in one direction and can be moved by hand or be actuated automatically in order to feed the cut material to the rotating knife disk 2. With the

ίο Cut trolley 1 is connected to a toothed belt 3, the follows the to-and-fro movements of the carriage. With one of the two pulleys (4) is another Roller 5 connected via a freewheel hub. This means that the belt 6 running over the roller 5 is intermittent is driven in one direction. This rotation is controlled via the electromagnetic clutch 7 the belt 8 and from this via a toothed belt wheel 9 to the feed roller and the chain wheels 10 fed, which are arranged at the same intervals one above the other and provided with spikes 11 chain belts the 12 wear. The conveying device can also be designed as a rake rotatable about an axis. the Chain belts 12 run over the driven sprockets 10 and over the rollers 13. When the electromagnetic If the clutch remains engaged, the leaflet cut from the rotating knife disk 2 becomes taken up by the spikes 11 and by a movement / cycle of the cut goods wagon 1 thereby driven chain belts 12 up to the outer bursting end, close to the rollers 13 promoted. According to FIG. 2, the chain belts can be driven in place via an electromagnetic clutch be done by an electric motor. When the chain belts 12 come to a standstill, a control command is issued by a microswitch, not shown, to the drive 15 of the offshoot 16. which is in the manner of a racket on an arm 17 about an axis lying below the cut material in the direction of the disk-shaped Storage plate 18 or to the rectangular storage plate 18 'is pivoted. The offshoot 16 is designed like a comb and engages behind the chain belts 12, so that the cut material in front of the offshoot 16 on the spikes 11 of the Keuenband 12 is held in a vertical position. During this movement, the offshoot or club releases the clippings from the spikes and conveyed them to the plate, on which a parchment paper is expedient or a plate was placed.

However, if the magnetic coupling 7 is disengaged early, the cut material will not be transported more to the end of the chain straps. The clippings are a little earlier, z. B. in the middle of the plate '»8 resp. 18 'filed.

It is thus possible, by appropriate preselection of the disengagement time of the clutch 7, without the To move the depositing plate 18 or 18 ', the clippings are flaky and parallel to the chain belts 12 to discard. In the case of a disc-shaped depositing plate, it is useful if the depositing is along a diameter he follows. The coupling is activated automatically, on the one hand, by the nose 19 on the clippings trolley 1 and microswitch 20. By selecting a cut material placement scheme (e.g. narrow or wide scaled or fanned) and pressing the corresponding key on the key selector 22 on the other hand a certain temporal pulse graduation is preselected on the pulse circuit 21. With every return of the cut goods wagon 1 is triggered by the microswitch 20 a delay interval of the time

staggering retrieved, whereby the clutch 7 accordingly is disengaged. Do the time intervals differ from the moment the microswitch 20 is struck only a little, so the clippings are closely staggered or flaked in a line parallel to the chain belts 16 lying. In the case of larger time intervals, the clippings are staggered further.

Instead of the above arrangement, another mechanical-electrical embodiment has been found proven. On the reciprocating toothed belt 3, a wedge is arranged, which has an adjacent Roll a lift depending on the feed path! deflects with a fixed pivot point. So the one The lever arm describing the arc of a circle carries at its end a permanent magnet, which is below the Swivel range of the lever operated magnetic switch. By preselecting a pattern to be placed on the clippings Certain magnetic switches with chip are placed on the button selector at a certain time interval voltage applied, so that when the permanent magnet is swiped over the lever arm, only this magnetic switch Forward staggered electrical control commands to the magnetic coupling. The staggered deployment times the coupling require a flaky or fanned placement of the clippings.

However, since it is advisable to stagger the clippings not only in one direction, but also in two dimensions (ν, ν or y. Φ) using the entire surface of the depositing plate, a control is provided that enables the plate to be advanced step by step. The microswitch 23, which forwards a trigger command to the electronics 24, is located in the pivoting range of the arm 17. The desired number of steps by which the ratchet wheel 28 is to be moved further is entered by preselecting the key selector 22. The electronics 24 then emit cmc with the same number of pulses with the number of steps, whereby the magnet 25 is briefly excited and the iron core 26 is attracted. This movement against the force of the spring 31 is transmitted by means of the pawl 27 to the ratchet wheel 28, which is firmly connected to the pinion 29. The pinion 29 engages in the ring gear 30 or in the rack 30 '. The step-by-step movement of the ratchet wheel 28 and thus of the pinion 29 caused by the electromagnet 25 therefore has the rotation *. the displacement (y) of the shelf to follow

So z. B. by programming the button selector, the electronics 24 emit two electrical pulses, the magnet 25 attracts twice. the pawl will rotate the ratchet wheel 28 by two detent positions and the plate 18 with the rack JO due to the rotation of the pinion 29 will be displaced by two intervals. This would result in a loose staggering of the cut material in the normal direction to the conveyor device 12. Instead of the simple pinion 29 engaging in the rack 30, a gear can of course also be provided so that the feed length per pulse reaches a suitable level

Instead of g reasons of Übersichtlickeit related to the F i. 1 selected embodiment, the following construction proves to be favorable: The electromagnet rotates the axis of an ireilaul gear via a one-armed lever, which is thereby intermittently drivable in one direction. This engages directly or via a further toothed wheel with the toothed rack 30 of the depositing plate 18 and moves the latter in accordance with the number of pulses.

Furthermore, a brake 32 is also provided, which precisely defines the feed path of the conveyor device 12. As soon as the clutch 7 is disengaged, the brake is applied, creating the point at which the drop

ίο the clippings from the spikes 11 of the conveyor 12 takes place, is precisely determined.

The filing device can be programmed in various ways. With inserted disc-shaped For example, Ablcgeplatte can first

A full diameter (2r) must be placed in each case and the rotation (φ) then carried out. However, it is also possible to place them in concentric circles
Analogous to that in FIG. 1, the conveying device 14 is driven by means of a magnetic coupling 7, the conveying device is driven according to FIG.

The motor is activated by a switch 42, which is operated by the clippings trolley, when it reaches the front end position after cutting off a slice from the clippings. The motor is activated after a predetermined number of revolutions by an electronic device set to this number of revolutions Counting device 43 is switched off, so that the sprockets come to a standstill at a predetermined point come and the disc from the racket 16 is placed at the desired location of the Abcgcplatte 18 ' can

The counting device is controlled by an impu! .Sensor 22 supplied with pulses corresponding to the predetermined revolutions of the motor. The counter which reads the revolutions of the engine opens the switch 42 to switch off the engine as soon as the engine revolutions correspond to the input pulses.

The drive 15 of the racket 16 is carried out by a switch 44, which is driven by the cut goods carriage 1 on his Is actuated away after the cutting of the disc from the knife disc 2 away. The drive 15 sets an arm in motion that can pivot around a horizontal axis, on which the rake-like. ?around Lifting the disc from the spikes with its prongs between the chain straps gripping racket 16 attached is.

Successes, the shutdowns of the engine always a constant number of revolutions, so whoever the successively cut slices stored on einandergeschichtetin form of a stack, it there is also the possibility of assigning the slices in a row in an imbricated manner on the Ablegepiaue to, for example, when the engine after eight six, four and two revolutions is switched off

f "To put more lines of such scale-like angeordnetei discs, the Abtegeplatic zi the chain bands shifted gradually. You can shift the storage plate in the same way as in FIG . 1 he follow.
