Description

The invention relates to a cutting machine for separating slices from a strand-shaped material to be cut, according to the features of the preamble of claim 1.

From the DE 10 2010 026 439 A1 is a cutting machine for cutting food slices by means of a reciprocating carriage known. The cutting machine has a machine housing which has a rotating cutting blade and a stop plate arranged parallel to the cutting plane. The stop plate can be adjusted by a knob perpendicular to the cutting plane to adjust the cutting gap of the cutting machine and thus the strength of the separated food slices.

The EP 2 334 476 B1 also shows a cutting machine for separating slices of a string-shaped food, with an adjustable Stop plate, the disc thickness is adjustable. This cutting machine has an attachment element, which is placed from above on a blade guard ring and the stop plate in order to increase the stability at a certain cutting thickness. At the same time an undesired adjustment of the cutting thickness is prevented by a locking of the stop plate.

The DE 34 46 656 A1 shows a household cutting machine with an adjustable via an adjustment stop plate. The housing of this household cutting machine has on its upper side on the adjusting independently trained support slide. This is provided as an additional support for the stop plate, and is intended to prevent deformation of the stop plate at high cutting pressures.

The invention has for its object to provide a cutting machine that is universally applicable while having a high safety standard.

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

The cutting machine has a pivotable and / or displaceable pawl for limiting the maximum cutting thickness, which can be brought into engagement with the adjusting device and limits the maximum adjustable cutting thickness, in that the pawl forms a stop cooperating with the adjusting device. The pawl has a neutral position in which it is to limit the maximum cutting thickness in engagement with the adjusting device, and an actuated position in which the pawl is not in engagement with the adjusting device. Preferably, the Pawl between the neutral position and the actuated position switchable or actuated. This makes it possible, optionally, to set a defined cutting thickness limit value, the cutting thickness limit value being smaller than the maximum cutting thickness that can be set on the cutting machine.

Upon reaching the setting of the cutting thickness limit value, the stop blocks a movement of the adjusting device or a part or a component or a gear part of the adjusting device. Preferably, a movement of the adjusting device is blocked only in the opening direction by the pawl. Thus, a smaller cutting thickness than the cutting thickness limit can be set as usual. A greater cutting thickness than the cutting thickness limit requires a conscious intervention.

Neutral position refers to the position of the pawl, which is usually set during normal operation of the cutting machine. In the neutral position, the stop plate and thus the cutting thickness in a first range between cutting thickness zero or below zero and the maximum Schnittstärkengrenzwert on the adjustment can be set or adjusted to any value.

Actuated position refers to the position of the pawl that is temporarily switched after a deliberate manual intervention or a controlled control command or switching command to temporarily allow a greater cutting thickness than the maximum cutting strength limit.

In particular, it is provided that the pawl or the stop does not interact directly with the stop plate. Instead, that happens Interaction between pawl and adjusting. This embodiment has the advantage, inter alia, that the pawl is arranged completely within the machine housing and not in the area prone to contamination.

About the adjusting device, the stop plate can be adjusted parallel to the cutting plane. In particular, the adjusting device has a rotary handle, by the rotation of the stop plate is moved or adjusted parallel to the cutting plane.

The value of the cut thickness limit may be, for example, 5mm or 6mm or 7mm or 8mm or 9mm depending on the desired application range. The value of the largest cutting thickness that can be set on the cutting machine can be in the range of 15 mm to 25 mm.

It is envisaged that the cutting machine for separating slices is formed by a strand-like material to be cut, preferably a rope-shaped food. It can have a machine housing, which holds a circular blade rotating in a cutting plane and a stop plate arranged parallel to the cutting plane, which is adjustable with an adjusting device for adjusting the cutting thickness perpendicular to the cutting plane. Furthermore, the machine housing can support a carriage which can be displaced parallel to the cutting plane by means of a guide device. The carriage has a Schnittgutauflage on which the cutting material, preferably sausage or cheese is placed.

It has been found that, in practice, a relatively small pane thickness is sufficient for the normal field of application of a cutting machine. On the other hand, it is desirable for individual tasks to set a high cutting thickness so that even thick slices of food can be separated cleanly. The larger the cutting thickness is set, the larger the cutting gap in the cutting machine opens and the higher the risk of injury. With wide open cutting gap, the cutting edge of the rotating cutting blade is exposed and represents a corresponding risk potential.

In order to increase the reliability for a user of the cutting machine, it is therefore proposed according to the invention to optionally limit the maximum adjustable cutting thickness of the cutting machine. It is a pivotable and / or sliding pawl used, which cooperates with the adjustment for cutting thickness adjustment and limits the maximum adjustable cutting thickness to a defined maximum value. If a larger cutting thickness is required in individual cases, then the pawl can be disengaged from the adjusting device and then a greater cutting thickness can be set on the machine. Also, the cutting blade is more accessible for cleaning purposes with larger cutting thickness.

In one embodiment, it may be provided that the adjusting device has a recess or a slide track or a groove and engages the pawl for limiting the maximum adjustable cutting thickness in the recess or the slide track or the groove.

So that the reliability is increased for the operator in the normal application, it can be provided that the pawl has a neutral position, in which it with the adjustment to limit the maximum Cutting strength cooperates and has an actuated position in which the pawl does not cooperate with the adjusting device. The neutral position of the pawl is the position which the pawl in normal operation, ie when it is not operated occupies. The actuated position of the pawl is the position which occupies the pawl after an operation, ie after a deliberate engagement.

A particularly convenient operation results when it is provided in one embodiment that the pawl is driven via an actuator between the neutral position and the actuated position displaced and / or pivoted.

In the normal field of application increases the safety of the machine, because not too unintentionally an excessively large cutting gap is adjustable and thus the contact protection for the cutting edge of the cutting blade is very high. Only in exceptional cases, when actually a large cutting thickness is needed, a user must deliberately bring the pawl out of engagement with the adjustment in order to adjust a large cutting thickness can. So it is also possible to choose the maximum slice thickness range on the cutting machine larger than usual, since with this device the accident protection is increased.

In order to achieve a high degree of operational reliability despite comfortable operation, it can be provided that an input device is provided for inputting or reading in a code and a control device only after entering or reading in a correct code for moving and / or pivoting the pawl into the actuator Actuates actuated position.

In one embodiment it can be provided that the pawl is manually displaceable and / or pivotable via a handle between the neutral position and the actuated position.

For an ergonomically favorable operation of the cutting machine can be provided that the machine housing has a receptacle for the handle. The handle can be designed as a removable from the machine housing or from the receptacle handle, in particular as a key.

In particular, it may be provided in one embodiment to arrange the receptacle for the handle in the region of the user facing end side of the cutting machine. Alternatively, the receptacle for the handle can be arranged in the region below the movable carriage on the machine housing.

In one embodiment with a good operator safety can be provided that the receptacle has a matched to a connector of the handle adapter for inserting the handle or a lock cylinder for inserting a key.

By providing in one embodiment that the receptacle or the lock cylinder allows removal of the handle or the key only in the neutral position and blocked in the actuated position removal of the handle or key, a removal of the handle or the key is impossible when a large cutting thickness is set on the cutting machine. As a result, a user sees the Cutting machine at a glance on the inserted handle, if the machine is set a dangerously high cutting thickness.

In one embodiment, the pawl may be formed as a pivotable lever or as a pivotable tab. It is also conceivable that the pawl is designed as a pin or pin, preferably designed as a spring-loaded pin or spring-loaded pin. In particular, the spring can act on the pin or the bolt in the direction of the depression or on the slide track or the groove out to ensure a good interaction between the pawl and the adjustment even under adverse circumstances.

To increase operating safety, it can be provided that the pawl positively engages in the recess or the slide track or the groove of the adjusting device and is guided there such that the pawl only in a certain slice thickness setting of the neutral position in the actuated position and / or vice versa pivotable and / or displaceable. In particular, it can be provided that a pivoting of the pawl is possible only in the slice thickness setting zero or less than zero or only in the slice thickness setting that corresponds to the slice thickness limit.

In particular, it can be provided that the recess or the slide track or the groove has at least one point at an angle to the recess or the slide track or the groove extending recess, and the recess at this point allows pivoting of the pawl in the actuated position.

An advantageous embodiment can provide that the adjusting device for adjusting the cutting thickness has a control slide movably mounted in the machine housing with a control plate leading the stop plate and that the recess or the slide track or the groove is also arranged and / or formed on the spool.

Likewise, it may be provided in one embodiment that the adjusting device for adjusting the cutting thickness has a rotatable control disk with a control plate leading the stop plate and the depression or the slide track or the groove is arranged and / or formed on the peripheral surface of the control disk.

A simple adjustment of the cutting thickness is obtained by the spool or the control disk via a knob for adjusting the cutting thickness can be actuated.

It is advantageous that both the adjustment as well as the pawl are disposed within the machine housing. As a result, both the adjustment and the pawl are protected against contamination or manipulation.

The value to which the maximum cutting thickness is limited via the pawl, can be adjusted by, for example, the spool or the control disc is replaced with another spool or other control disc, each having a different shaped recess or slide track or groove.

The cutting machine according to the invention can be embodied in one embodiment as a so-called vertical cutter, in which the cutting plane of the cutting blade extends in the vertical direction.

In another embodiment, the cutting machine according to the invention may be designed as a so-called oblique cutter, in which the cutting plane of the cutting blade runs tilted against the vertical.

An application of the cutting machine according to the invention can be done, for example, in the food industry and / or fresh food for slicing food such as meat, sausage, fish or cheese.

Further embodiments of the invention are illustrated in the figures and described in the accompanying description.

An enlarged view in the area of the adjusting device.

The Figures 1-3 show a cutting machine 1 according to the invention for separating slices of a rope-shaped food. The cutting machine 1 has a machine housing 11, which a rotating cutting blade 12 holds. Furthermore, the machine housing 11 comprises a motor tower 16, which receives in its interior a motor for driving the rotating cutting blade 12.

The rotating cutting blade 12 is formed as a circular blade and arranged in a cutting plane A, which is tilted against the vertical. The FIGS. 1 to 3 therefore show a so-called oblique cutter or gravity cutter. Gravity cutter means that the separated discs supported by gravity fall into the storage area 18 of the machine housing 11.

The Fig. 1 shows a front view of the cutting machine, as seen from the front of a cutting machine user. In the figures, the cutting machine 1 is shown without a carriage. The slide was omitted for the sake of clarity. The machine housing 11 has a closed housing wall. This is in the representation of FIG. 1 However, in the region of the adjusting device 2 shown broken through to make visible within the machine housing arranged adjusting device 2.

The cutting machine 1 has a machine housing 11, which is closed at the top and also from below by a removable bottom plate is closed. In the interior of the machine housing 11, a construction space is arranged, in which individual components of the cutting machine, such as a motor or the locking device 2 or a control device for the engine, are added.

Via an input and control device 17, which is arranged on the front side of the machine housing 11, the cutting machine 1 can be switched on or off and / or programmed or parameterized.

In the Fig. 2 is a side view of the cutting machine 1 in the region of the cutting blade 12 and the stop plate 13 of the cutting machine 1 is shown. For the purpose of improved clarity was in the Fig. 2 the machine housing 11 is not shown.

The cutting edge of the cutting blade 12 is surrounded by a knife protection ring 14 C-shaped. The knife guard ring 14 secures the cutting edge of the cutting blade 12 against inadvertent contact. A knife cover 15 covers the central region of the cutting blade area. The blade cover 15 forms a shock protection to prevent the rotating blade from being accidentally touched. The Messererbadeckung 15 is removably attached via a holding device to the blade guard ring 14.

A stop plate 13 is arranged parallel to the circular blade 12 and displaceable by the adjusting device 2 perpendicular to the cutting blade plane A in order to adjust the cutting thickness and thus the thickness of the separated slices can.

In the Fig. 3 the adjusting device 2 is shown in an enlarged view. The adjusting device 2 has a control disk 26 which is rotatably mounted about an axis 26a. About a from outside the machine housing 11 accessible, not shown in the figures rotary handle, which is connected via the rotation axis 26a with the control disk 26, this can be rotated to adjust the cutting thickness. The control disk 26a has a spiral groove 26b in which a pin connected to the stopper plate 13 is guided.

The stop plate 13 is connected via a bent at a right angle Anschlagplattenfuß 13a with the adjusting device 2 and can be adjusted via the adjusting device 2 parallel to the surface of the machine housing 11. A seal 13 b is disposed on the surface of the machine housing 11 between the Anschlagplattenfuß 13 a to seal the passage opening of a holder of the stop plate on the machine housing 11.

The adjusting device 2 is completely disposed within the space enclosed by the machine housing 11 and thus well secured against contamination or manipulation. An adjustment of the cutting thickness of the cutting machine 1 is carried out by the control disk 26 is rotated, whereupon the pin connected to the stop plate 13 is guided by the spiral curve 26 b guided while the stop plate 13 entrains.

The control disk 26 has on its peripheral surface in the Fig. 2 shown groove 24. In this groove 24 engages in the Fig. 3 illustrated pawl 23 in the neutral position to limit the adjustable cutting thickness. In the neutral position, the pawl 23 is guided positively by the groove 24 during rotation of the control disk 26.
The control disk 26 is formed of a metal, preferably aluminum or brass or bronze or a plastic. The Control disk 26 has a small thickness relative to its diameter, but the thickness is dimensioned so that it forms a peripheral surface 26 c, in which the groove 24 and the recess 25 can be introduced. The control disk 26 can be produced as a casting or as a milled part.

A variation of the maximum adjustable in neutral position cutting thickness can be achieved by a control disk 26 is replaced with another control disk 26, the groove 24 has a different length. The beginning of the groove 24 is selected in the control disk 26 so that in the neutral position is always a value of the cutting thickness is less than zero adjustable. Cutting thickness less than zero means that the stop plate moves completely in front of the cutting edge of the cutting blade 12 so that it is covered by the stop plate and the C-shaped blade protection ring around and the risk of accidents is minimized.

The axis of rotation 26a of the control disk 26 has a round cross section, which is flattened on one side, so that the control disk 26 can be placed on the axis of rotation 26 only in a defined angular position. This ensures that the position of the groove 24 is defined exactly relative to the position of the stop plate 13. Over the length of the groove 24 can be adjusted so the exact cutting thickness.
The cutting thickness can be adjusted in the neutral position of the pawl 23 in a range of less than zero continuously up to the cutting thickness limit. When the cutting thickness limit is reached, the pawl 23 forms a stop and limits further rotation of the control disk 26 by the end of the groove 24 comes into abutment with the pawl 23. Depending on the length of the groove 24, the exact value of the slice thickness limit can be set. In practice, it has turned out to be It has proved advantageous to select a value in the range between 5 mm and 9 mm as the maximum value for the cutting thickness in the neutral position.

The groove 24 has, as in Fig. 2 it can be seen, in its end region on a perpendicular to the groove 24 extending recess 25. This end region, on which the recess 25 branches off from the groove 24, represents the position at which the control disk 26 comes into abutment with the pawl 23. At this position, the pawl 23 can be pivoted from the neutral position to the actuated position and back. In this case, the pawl 23 is disengaged from the locking disc 26 and this can be further rotated to further open the cutting thickness of the cutting machine.

For rotating the pawl 23, a handle 22 is provided, which is inserted into a arranged on a wall of the machine housing 11 receptacle 21. The introduced into the receptacle 21 handle 22 is rotatably connected to the pawl 23. The receptacle 21 has an adapter which is matched to the shape of the handle 22. Thus, the handle 22 is a key. Only one handle with specially adapted to the adapter shape is inserted into the receptacle 21. Also, the receptacle 21 is designed such that it secures the handle 22 as soon as it is rotated and thus leaves the neutral position. This means that the handle 22 can be inserted into the receptacle only in the neutral position or removed from the receptacle. Once the neutral position of the pawl 23 is adjusted, the handle 22 is held by the receptacle 21 and is no longer removable from the machine housing 11. This allows a user on the machine to see at a glance that the pawl 23 is in the actuated position and thus the cutting machine 1 allows a greater cutting thickness than is provided in normal operation. A reset of the handle 22 from the actuated position to the neutral position by adjusting the cutting thickness to the cutting thickness limit value. In this position, the recess 25 is again in alignment with the pawl 23 so that it can be brought into engagement with the groove 24. After pivoting the pawl 23 in the neutral position, the handle 22 can be removed from the cutting machine 1.
