Description

cutting machine

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 DE 10 2010 026 439 A1 a cutting machine for cutting food slices by means of a reciprocable carriage is 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 the cutting gap of the cutting machine and thus the strength of the separated

To adjust food slices.

EP 2 334 476 B1 also shows a cutting machine for separating slices of a strandformigen food, with an adjustable On impact 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.

DE 34 46 656 A1 shows a household cutting machine with an adjusting device adjustable via a stop plate. The housing of this household cutting machine has on its top one of the

Adjustment device independently trained support slide on. This is provided as an additional support for the stop plate, and is a

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 by the pawl with the adjusting device

interacting stop forms. 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 engaged with the adjusting device. Preferably, the Pawl between the neutral position and the actuated position switchable or actuated. So it is possible, optionally a defined

Set cutting thickness limit, wherein the cutting thickness limit is smaller than the maximum cutting thickness adjustable on the cutting machine.

The stop blocks when reaching the setting of the

Schnittstärkengrenzwerts 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 larger 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 can be adjusted or adjusted to any value in a first range between cutting thickness zero or below zero and the maximum Schnittstärkengrenzwert on the adjusting device.

Actuated position refers to that position of the pawl, which after a deliberate manual intervention or an unconscious control command or

Switching command is temporarily switched to temporarily a larger one

Cutting thickness as the maximum cutting thickness limit.

In particular, it is provided that the pawl or the stop does not interact directly with the stop plate. Instead, that happens Cooperation between pawl and adjusting device. These

Among other things, the design has the advantage that the pawl is arranged completely inside the machine housing and not in the machine housing

Pollution prone area.

About the adjusting device, the stop plate parallel to the

Cutting plane to be adjusted. 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, as desired

Scope of application. 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 holds with a

Adjusting device for adjusting the cutting thickness perpendicular to the

Cutting plane is adjustable. 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, a large

Adjust cutting thickness to be able to separate even thick slices of food clean. 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 provides a corresponding

Danger 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 used a pivotable and / or sliding pawl, which cooperates with the adjusting device 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 larger 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 can 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 adjusting device for limiting 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, d. H. if not ingested. The actuated position of the pawl is the position which the pawl upon actuation, d. H. after a conscious intervention.

A particularly comfortable operation results when in one

Design is provided that the pawl via an actuator

driven between the neutral position and the actuated position

is displaceable and / or pivotable.

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 consciously disengage the pawl with the

Bring adjustment device to adjust a large cutting thickness can. So it is also possible, the maximum Schnittstärkenbereich at the

Cutting machine to choose 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 the actuator

Moving and / or pivoting the pawl in the actuated position activates. 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 a receptacle for the

Has 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 recording for the

Handle in the area below the movable carriage on the

Machine housing to be arranged.

In one embodiment with a good operator safety can be provided that the recording on a connector of the handle

matched adapter for inserting the handle or a

Has lock cylinder for inserting a key.

By providing in one embodiment that the receptacle or the lock cylinder only in the neutral position allows removal of the handle or the key and in the actuated position, a removal of the

Blocked handle or the key, a removal of the handle or the key is impossible if the cutting machine a large

Cutting thickness is set. 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 bolt or pin, preferably as

spring-loaded bolt or spring-loaded pin is formed. 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 adjusting device even under adverse circumstances.

To increase the 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 is pivotable and / or displaceable only in a certain Schnittstärkeneinstellung of the neutral position in the actuated position and / or vice versa. In particular, it can be provided that a pivoting of the

Pawl only in the cutting thickness setting zero or less than zero or only in the cutting thickness setting that corresponds to the cutting thickness limit is possible.

In particular, it can be provided that the recess or the slide track or the groove has at least at one point 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 may provide that the adjusting device for adjusting the cutting thickness has a control slide movably mounted in the machine housing with a control path 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 of a rotatable

Control disc having a control plate leading the stop plate and the recess or the slide track or the groove disposed on the peripheral surface of the control disc and / or is formed.

A simple adjustment of the cutting thickness results by the

Control slide or the control disk via a knob for adjusting the cutting thickness is actuated.

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

Tamper-proof.

The value to which the maximum cutting force is limited by the pawl can be adjusted by, for example, replacing the spool or the control disc with another spool or other control disc, each with a different shape

Recess or slide track or groove have. 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

For example, in the food industry and / or in the fresh produce for slicing food such as meat, sausage, fish or cheese done.

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

Show it:

Fig. 2: A side view of the cutting machine without machine housing; Fig. 3: An enlarged view in the region of the adjusting device.

FIGS. 1-3 show a cutting machine 1 according to the invention for separating slices from a rope-shaped foodstuff. The

Cutting machine 1 has a machine housing 1 1, which a rotating cutting blade 12 holds. Further, the machine housing 1 1 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 figures 1 to 3 therefore show a so-called oblique cutter or

Gravity Schneider. Gravity cutter means that the separated slices supported by gravity in the storage area 18 of the

Machine housing 1 1 fall.

Fig. 1 shows a front view of the cutting machine, as seen by a user standing in front of the cutting machine. In the figures is the

Cutting machine 1 shown without a carriage. The slide was omitted for the sake of clarity. The machine housing 1 1 has a closed housing wall. However, in the representation of FIG. 1, this is illustrated broken through in the region of the adjusting device 2 in order to make visible the adjusting device 2 arranged within the machine housing.

The cutting machine 1 has a machine housing 1 1, which is closed at the top and also from below by a removable bottom plate is closed. In the interior of the machine housing 1 1, a 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. About an input and control device 17, which is arranged on the front of the machine housing 1 1, the cutting machine 1 can be turned on or off and / or programmed or parameterized.

FIG. 2 shows 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. For the sake of clarity, FIG

Machine housing 1 1 not shown.

The cutting edge of the cutting blade 12 is embraced by a knife protection ring 14 in a C shape. The knife guard ring 14 secures the cutting edge of the

Cutting knife 12 against accidental contact. A knife cover 15 covers the central region of the cutting blade area. The

Knife cover 15 forms a shock protection to prevent the rotating cutting blade from being accidentally touched. The

Messerbadeckung 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 of the adjusting device 2 perpendicular to the cutting blade plane A.

slidable to adjust the cutting thickness and thus the thickness of the separated slices can. In 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 one of outside the

Machine housing 1 1 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 angled at a right angle

Stop plate 13a connected to the adjusting device 2 and can be adjusted via the adjusting device 2 parallel to the surface of the machine housing 1 1. A seal 13b is on the surface of the

Machine housing 1 1 arranged between the Anschlagplattenfuß 13 a to the passage opening of a holder of the stop plate on the

Seal machine housing 1 1.

The adjusting device 2 is completely within the of the

Machine housing 1 1 arranged space arranged and thus well secured against contamination or tampering. 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 26b guided while the stop plate 13 entrains.

The control disk 26 has on its peripheral surface a groove 24 shown in FIG. In this groove 24 engages the pawl 23 shown in FIG. 3 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 against another

Control disk 26 is replaced, the groove 24 has a different length. The beginning of the groove 24 is selected in the control disk 26 so that in

Neutral position is always a value of the cutting thickness smaller than zero is 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 they pass through the

Cover plate and the C-shaped knife protection ring covered all 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 as the exact

Set the cutting thickness.

The cutting thickness can be in the neutral position of the pawl 23 in a

Range from less than zero steplessly up to the cutting thickness limit. When the cutting strength 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 it

Cutting thickness limit. In practice, it has turned out to be Advantageously, as the maximum value for the cutting thickness in the

Neutral position to choose a value in the range between 5 mm and 9 mm.

The groove 24 has, as can be seen in Fig. 2, in its end a

at right angles 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.

To rotate the pawl 23, a handle 22 is provided, which is inserted into a arranged on a wall of the machine housing 1 1 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 specifically on the adapter

tuned shape can be used in 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 used only in the neutral position in the recording or from the

Recording is removable. 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 1 1. 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 the

Cutting thickness is set to the cutting thickness limit. 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 this

Pivoting the pawl 23 in the neutral position, the handle 22 can be removed from the cutting machine 1.
