Description

The invention relates to a cutting machine for separating slices for food according to the features of the preamble of claim 1.

Such a cutting machine is for example from the DE 299 10 411 U1 known. There, a cutting machine is shown, which separates individual slices of string-shaped foods, such as sausage or cheese, a cutting blade and transported them over a chain frame away from the cutting blade. A hinged extension releases these discs from the chain frame and transports them to a conveyor belt. The offshoot is pivotally mounted about a pivot axis on the machine housing of the cutting machine and is pivoted via an electric drive. The attachment of the offshoot takes place on the outside of the cutting machine housing. This allows good accessibility of the attachment, however, the offshoot has a relative long connecting linkage, which can be detrimental to fast dynamic movements.

Also from the WO 2008/135219 A1 is a corresponding cutting machine with a motorized pivotable offshoot known. Again, the offshoot is attached to the outside of the cutting machine housing.

The invention has for its object to provide a cutting machine, which is mechanically stable and has a high cutting performance.

This object is achieved by a cutting machine with the features of claim 1.

According to the invention, it is provided that the cutting machine has a connection to which an extension is detachably connected and can be pivoted about a horizontally extending pivot axis. The terminal forms the horizontal pivot axis and extends through an opening in a housing wall of the machine housing in the direction of the cutting plane, so that the offshoot is connectable from the cutting plane forth via a screw or bayonet connection to the terminal. By arranging the terminal on the cutting machine on the side of a housing wall of the machine housing which faces towards the cutting plane, the terminal moves closer to the center of mass of the chip. The connecting rod of the offshoot can be made relatively short. This causes lower torsions due to the moving masses to occur during the pivotal movement of the offshoot. During the pivoting of the offshoot is therefore subjected to lower vibrations. Dar offshoot can therefore with the same or improved mechanical stability be constructed more easily, which additionally improves the dynamic behavior. In particular, if large or heavy slices of sliced products are to be released from the sliver from a chain frame, this is of decisive advantage since the slab has a lower tendency to oscillate as a result of the better mass distribution. On the one hand, this leads to a more mechanically stable structure of the chip and, on the other hand, greater cutting speeds can be achieved.

The cutting plane is that plane in which the cutting blade rotates. In a cutting machine designed as a vertical cutter, the cutting plane extends vertically. In a diagonal cutter, the cutting plane is inclined to the vertical. The separation of individual slices takes place by a slide guided linearly on the machine housing serving as Schneidgutauflage and delivered to this slide cutting material delivered to the cutting blade and separated by reciprocating the carriage of the cutting blade individual slices. The carriage can be moved manually or by motor.

The connection is preferably designed as a mechanical connection, which has a housing opening for the mechanically fixed connection or connection of the Ablegers with the cutting machine. The opening points in the direction of the cutting plane, so that the offshoot can be connected to the connection from the cutting plane. In particular, the cutting machine has a housing wall section, which is arranged at a distance from the cutting plane or the stop plate and in the region of which the connection faces inwards, ie, is directed towards the cutting plane. Preferably, this housing wall section extends vertically and has one the cutting plane directed towards opening through which the terminal passes.

In one embodiment, provision may be made for the connection to have a plug-in axis or hub which is rotatably mounted in the machine housing and which can be positively and non-positively connected to the extension in order to detachably hold it. About the positive connection between the offshoot and thru axle or hub is made possible that the angle between the offshoot and the thru axle or hub always remains the same. Thus, position errors are avoided by incorrect installation of the offshoot. About the non-positive connection of the offshoot with the connection mechanically fixed and in particular releasably connected. Thus, the offshoot can also perform very fast swivel movements. The thru axle or the hub is rotatably mounted in the machine housing and points with its free end in the direction of the cutting plane or to the cutting blade.

A positive connection between the offshoot and the connection can be made by providing that the connecting element has a groove, into which engages a projection of the plug-in axis or the hub, or that the connecting element has a projection which is in a groove of the plug-in axis or the hub engages.

A positive connection between the branch and the connection can be made by a screw with a threaded or a bayonet connection with a bayonet pin.

In one embodiment it can be provided that the offshoot for detachable mounting on the cutting machine has a connecting element that with connectable to the terminal. The connecting element can be mechanically fixed and yet easily releasably connected to the plug-in axis or the hub by jamming or screwing. It is preferably provided that either the thru axle or the hub engages through the housing wall of the machine housing in the direction of the cutting plane and the connecting element is placed outside of the machine housing on the thru axle or the hub, or the housing wall of the machine housing in the direction of the cutting plane has directed opening and the connecting element engages in this opening and is placed within the machine housing on the thru axle or the hub. In order to avoid contamination of the connection, it can also be provided that the housing wall has a seal in the region of the connection, which prevents dirt from entering the interior of the machine housing.

In particular, it can be provided that the offshoot has a connecting element with an opening through which a screw or a bayonet pin engages, wherein the screw or the bayonet pin is held captive in the opening and has on one side a handle or a tool holder.

The tool holder is used to mount via a tool or a key the offshoot, d. H. to establish or release a connection between the branch and the connection of the machine housing.

In order to enable a comfortable operation of the cutting machine and in particular to be able to dismantle or assemble the offspring quickly, it can be provided that the screw or the bayonet pin has a handle having. This allows a tool-free attachment of the offshoot to the connection of the machine housing.

In one embodiment it can be provided that the handle or the tool holder is aligned with the mounted on the machine housing offshoot to the cutting plane and shows the thread of the screw or the bayonet of the bayonet pin away from the cutting plane.

In particular, it can be provided that the offshoot has a plurality of tines extending parallel to one another, which project freely at one end and are fastened to a rod at its other end. The rod holds at its end remote from the tines the connecting element and extends in a straight line from the tines to the connecting element. Due to the straight course of the rod from the tines of the offshoot to the connecting element or the connection results in a particularly short way for the power transmission of the offshoot. The short path minimizes mechanical deformation as the chopper moves and reduces the sway angle of the chopper at high cutting speeds. The rod may be formed as a hollow rod to reduce the mass of the offshoot. In an alternative embodiment, the rod may be formed from a solid material. In particular, it is provided that the offshoot is made of a metal, such as stainless steel.

A height adjustment of the offshoot or a compensation of positional tolerances can be realized by the offshoot is mounted vertically adjustable on the cutting machine. Preferably, either the length of the rod can be extended, or the connecting element has two in Longitudinally spaced openings and a screw or a bayonet pin can be inserted either in the first or in the second opening.

A height adjustment of the offshoot can also be realized by providing that the rod is formed telescopically between the connecting element and the first prong of the offshoot. Alternatively, the rod can hold the connecting element length-adjustable via a thread.

For an automatic power-operated drive of the offshoot can be provided that the machine housing for pivoting the offshoot has received within the machine housing electromagnetic solenoid with a plunger. The plunger is connected to a pivot lever, which in turn is rotatably mounted on the axle or the hub.

In order to enable a cleanly defined deposit image at high cutting speeds, it can be provided in one embodiment that the pivoting path of the plug-in axis or the hub is limited by a displaceable stop being mounted on the pivoting lever. The stop comes into contact with a held in the machine housing elastic buffer during pivoting. This ensures an always same swivel range. About the sliding stop the swivel range of the offshoot can be accurately adjusted and adjusted. An elastic buffer prevents a hard stop at the end of the pivoting path. To set the pivoting range of the offshoot can be provided that the position of the stop on the pivot lever and / or the position of the elastic buffer in the machine housing is adjustable to adjust a swivel range of the offshoot.

The separated from the cutting blade discs are taken from the chain frame, transported by means of transport chains transversely to the cutting blade. From the offshoot, the discs are then removed from the chain frame and transported to a storage area. In the storage area, the discs are placed or stacked on a storage table. For easy removal of the stored items to be cut or for a simple cleaning can be provided that the machine housing releasably supports the arranged in the storage area storage table. The storage table is arranged in a recess of the machine housing, which is bounded on one side by the cutting plane, preferably the stop plate, and on the opposite side by a vertically extending portion of the housing wall of the machine housing.

A simple assembly of the offshoot on the machine housing can be achieved by providing that the tray inserted into the recess is arranged below the connecting element with the mounted offshoot. Thus, despite the inwardly directed connection for mounting the Ablegers an easily accessible connection allows. Even when mounted on the cutting table, the connection of the offshoot and the connecting element are freely accessible.

In particular, it is provided that a drive device of the offshoot, comprising the lifting magnet and the plug-in axis or the hub, is accommodated within the cutting machine housing in a construction space which in the Cutting machine housing is arranged above the tray inserted into the recess.

In the embodiments of the invention shown in the figures, the same parts are each provided with the same reference characters. In the Fig. 1 is a first embodiment of a cutting machine 1 for separating slices of particular stranded cutting material shown. It is a food cutting machine 1, which has a machine housing 11 on which the following components are mounted, a drive motor and a cutting blade 2 rotatably driven by the latter in a cutting plane for cutting individual slices of the material to be cut and a stop plate 12 movable parallel to the cutting plane for setting a desired pane thickness and a chain frame 14, which cooperates with an offshoot 4 to transport the cut slices to a storage area 16, wherein the offshoot 4 to a terminal 5 of the machine housing 11 detachably, that is removably connected and to a horizontally extending Swivel axis S can be swiveled.

The machine housing 11 of the cutting machine has a substantially rectangular base on which a motor tower 15 projects upwards. In this engine tower 15 of the drive motor, not shown, is added. The drive motor is connected via a gear with the cutting blade 2 and drives this. The cutting blade 2 is designed as a circular blade. At the top of the motor tower 15, an operating and / or display unit for operating the cutting machine 1 is arranged.

The cutting blade 2 is covered in the region of the cutting edge by a C-shaped blade guard ring 22 to prevent inadvertent contact with the cutting edge of the cutting blade. The front side of the cutting blade 2 is secured with a flat blade cover 21. at the illustrated cutting machine 1 is a so-called vertical cutter, ie the cutting blade 2 is formed as a circular blade, which rotates in a vertically oriented cutting plane. The cutting area of the cutting blade 2 is defined by the area left clear by the blade protection ring 22. Before the cutting area, the stop plate 12, which is displaceable parallel to the cutting blade 2, is arranged. About a turntable 13, the stop plate 12 can be adjusted manually to set a desired slice thickness.

In the area in front of the cutting blade 2, a carriage 3, which is displaceable parallel to the cutting plane, is arranged. The carriage has a carriage foot 34 which is mounted in the machine housing 11 on a linear guide. Further, the carriage 3 comprises a support plate 31 for supporting cutting material. In the area in front of the carriage, i. facing an operator, the carriage 3 comprises a hand guard 32. About a Schneidguthalterung 33 is held to be cut cutting material and delivered to the cutting blade 2 during the cutting operation. By manually moving back and forth of the carriage 3 2 individual slices are separated from the strand-like material to be cut with the cutting blade.

The separated from the cutting blade 2 discs are received in the area behind the cutting blade of a chain frame 14 and conveyed across the cutting blade. About the pivotable extension 4, the discs are released from the chain frame and placed on a storage table 17 in the storage area 16. The storage table 17 is arranged in a recess of the machine housing 11. The machine housing limits the depression on the one hand by the displaceable stop plate 12 or the cutting plane and on the other hand by a vertically extending portion 18th the housing wall of the machine housing 11. In the vertically extending portion 18, a terminal 5 is arranged, on which the branch 4 by means of a connecting element 42 is releasably supported.

In the Fig. 2 another example of a cutting machine 1 is shown. For the sake of clarity is in the Fig. 2 the carriage as well as the blade cover and the knife guard ring are not shown. The in the Fig. 2 shown cutting machine is in large parts with the in FIG. 1 shown cutting machine match. As a difference to the in Fig. 1 shown cutting machine, has in the FIG. 2 cutting machine shown a motorized adjustment of the stop plate 12 and a motor-driven carriage. In addition, the engine tower 15 is designed slightly larger, ie the engine tower 15 can accommodate a stronger drive motor.

In addition, the in Fig. 2 shown cutting machine 1 substantially the same components as in Fig. 1 shown cutting machine, so that the rest of the description applies to both versions.

The branch 4 is connected via a in the vertically extending portion 18 of the housing wall of the machine housing 11 via the connecting element 42. The branch 4 is designed as a fork-off device 4 and comprises the connecting element 42 and has a vertical bar 41 on which a plurality of mutually parallel tines 451, 452, 453, 454, 455, 456 are attached. The tines 451, 452, 453, 454, 455, 456 are connected at one end to the rod 41, for example by welding or soldering. They collar freely at the other end. They are horizontal The rod 41 extends straight from the tines to the connecting element 42. This allows a power transmission from the terminal 5 to the branch 4 with a very short transmission path. This avoids instabilities that could cause possible vibrations of the offshoot.

About one in the Fig. 3 and 6 shown drive device, the offshoot 4 is pivoted to place the discs on the storage table 17. The drive device has a solenoid 54 and is covered by an outer wall 19 of the machine housing and secured against contamination. In the Fig. 3 the cutting machine is shown with the outer wall 19 removed. In the space B of the machine housing 11 of the solenoid 54 is added. The pivoting of the offshoot 4 is limited by elastic buffer elements 53.

The function of the drive device can the representation of Fig. 6 be removed. The solenoid 54 is actuated via a plunger 55, the pivot lever 52. The pivot lever 52 is rotatably connected to the plug-in axis 51 of the terminal 5 in order to pivot about the pivot axis S. The pivot lever 52 holds at its lower end an adjustable stop element 56. When pivoting the Ablegers 4 the stop element 56 comes at the end of the pivoting area in contact with one of the buffer members 53 and limited in this way the pivot angle. The stop element 56 is screwed by 2 screws with the pivot lever 52. After loosening the two screws, the stop element 56 can be adjusted relative to the pivot lever 52 and in new Be tightened position. As a result, the pivoting range of the offshoot 4 can be adjusted.

In the Fig. 4 an enlarged detail in the area of the terminal 5 is shown. The branch 4 has at the lower end of its bar 41 a connecting element 42. Via a lock nut 44, the position of the connecting element 42 on the rod 41 can be adjusted. The locknut 44 is disposed on the rod 41 between the connecting member 42 and the first prong 456 as viewed from below. By the displacement of the connecting element 42 along the rod 41, the height of the offshoot 4 is adjusted relative to the chain frame 14.

In the connecting element 42, a screw 43 is received with a handle 431. About this screw 43, the connecting element 42 is connected to the terminal 5, which is arranged in the vertically extending housing wall 18 of the machine housing 11 and facing the cutting plane.

Like in the Fig. 5 is shown, the terminal 5 has a plug-in axis 51 which is rotatably mounted within the machine housing. The pivot axis S extends through the plug-in axis 51 therethrough. The plug-in shaft 51 is rotatably connected to the actuated by the solenoid 54 rocking lever 52 and can be pivoted by this about the pivot axis S.

The connecting element 42 of the offshoot 4 is frictionally connected via the screw 43 with the plug-in axis 51. The screw 43 has a captive 433 on its threaded pin. The captive 433 is formed as a disc which engages around the thread of the screw 43 and a larger diameter than the opening 421 of the connecting element 42nd having. As a result, the screw 43 is held captive in the opening 421 of the connecting element 42. By turning the handle 431, the screw 43 can either be attached to the thru-axle 51 or detached therefrom, in order either to connect the extension 4 to the cutting machine 1 or to detach it from the cutting machine 1.

The storage table 17 is detachably mounted on the machine housing 11. The machine housing 11 has a further drive device to move the tray table 17 in a linear direction, parallel to the cutting plane. This method of the tray table is synchronized with the disc transport of the offshoot 4, for example, to store two-dimensional filing figures. The cutting machine 1 has a control device, not shown, which is connected to the chain frame 14, the offshoot 4 and the storage table 17 to control these synchronously with each other. Thus, either stacks can be formed from the separated slices or the separated slices can be partially overlapped, that is, be stored on the storage table 17 in a scaled fashion. Other two-dimensional lay-up figures can also be formed in this way.
