Description

The invention relates to a disc cutting machine for cutting slices of particular stranded cutting material, preferably food, with a machine housing, which supports a drive motor and a driven by the drive motor rotating cutting blade, and arranged in the cutting knife storage area with a substantially planar storage plate for receiving separated discs, wherein the tray is detachably coupled by means of a coupling device to the machine housing or to an attachment of the machine housing, wherein the tray is coupled during the cutting operation in a horizontal operating position and outside the cutting operation in at least one removal position movable, in which the tray dissolved and can be removed from the coupling device.

In such a slicing machine, the sliced material, in particular in automatically operated slicing machines for rope-shaped foods, such as sausages, ham, salmon, cheese, etc., is moved against the cutting blade for cutting slices.

The drive of the cutting device is carried out by the drive motor, which is usually enclosed to protect against splashing water and contamination and for mechanical protection against external interference from the machine housing.

The separated discs then enter either automatically or by a storage device, for example by a motor-driven chain frame in the storage area. There they are stored on the shelf.

The shelf serves to receive the cut slices. Furthermore, the tray may be connected to a weighing device, so that the weight of the cut slices, thus the total amount of cut, can be detected directly.

Especially in the food industry, there are regularly particularly high demands on the hygiene to be ensured.

Therefore, a regular thorough cleaning of the slicer and in particular the shelf is essential. For this purpose, the tray can be moved into a removal position. In this removal position, the tray can be removed for cleaning.

When cleaning is complete, it is re-mounted in the slicing machine so that subsequent slices can be cut and collected on the tray.

Such a generic slicing machine is from the DE 10 2014 113 505 A1 or the DE 17 51 114 U known.

The DE 88 07 446 U1 describes a cutting device with integrated weighing device, wherein by means of a coupling device, a weighing plate via an angled Carrier bracket above the -not interchangeable designed-storage plate can be attached.

In the DE 17 51 114 U the shelf is releasably connected by means of a spring device attached on one side to the underside of the machine housing.

In the DE 10 2014 113 505 A1 a storage plate is provided with a rotation axis, so that the storage plate can be rotated in a vertical removal position.

To remove the tray must first be rotated in the vertical removal position and then moved along the axis of rotation of a coupling device for coupling the tray with the remaining disc cutting machine laterally.

It would be desirable to have a simpler removal and return option for the shelf. For example, it is often difficult for reasons of space to tilt the shelf to the vertical as well as to move laterally. When tilting into the vertical, it can also happen that cutting residues fall from the tray, for example, behind or next to the rest of the slicing machine or slip, so that there is then additionally to clean.

It has also been found that in such a disk cutting machine in the prior art, the coupling device itself is relatively strongly bent and thus difficult to clean.

In a disk cutting machine according to the prior art, therefore, it requires a considerable effort and comfort waiver in order to ensure the necessary hygiene, especially the shelf, regularly.

Object of the present invention is therefore to improve a generic disc cutting machine, in particular with respect to their tray.

According to the invention, this object is achieved in a surprisingly simple and effective manner in that the coupling device has an upper and a lower coupling arm, wherein the two coupling arms along a longitudinal direction form a coupling recess open on one side for coupling the tray, and in that the coupling device is formed is that the tray is inserted directly and without an intermediate piece in the coupling recess and aligned in the operating state of the disc cutting machine parallel to the longitudinal direction of the coupling recess.

This makes it possible to insert the tray into or out of the coupling recess. This may already be enough for a slight tilting or lifting. It is therefore not necessary to bring the tray first completely in the vertical. The installation and / or removal of the shelf can also be done without tools.

The two coupling arms can be a receptacle for receiving the tray, in which the tray is clamped to the coupling device. The recording can be in the form of a Gripper be formed. The clamping can in particular be formed gravitationally resulting.

The coupling recess may, when the disc cutting machine is brought into its usual horizontal installation or Aufstellungslage, projecting into the vertical. Then, for example, the tray may have a rear handle projecting perpendicular to its substantially planar plane. For mounting, the rear grip can then engage in the vertical coupling recess or be inserted into it. The rear grip can thus be fixed between the two coupling arms, in particular releasably. The rest of the tray can then be supported on the coupling device.

In a particularly advantageous class of embodiments of the invention, the coupling recess in the horizontal and preferably not in the vertical, be open. For this purpose, the two coupling arms can be aligned in the horizontal and / or substantially in the horizontal.

Thus, for installation and / or disassembly of the shelf this easy laterally, optionally obliquely against the horizontal, between the coupling arms, d. H. be pushed into the coupling recess and pulled out from there.

It can also be provided that the coupling device and / or the storage plate have or form a fixing device for the horizontal fixing of the storage tray in its operating position. Under operating position, the position of the shelf is to be understood, in which it is used to store cut slices.

The fixing device can be effectively prevented, in particular unintentional, lateral slipping out of the tray from the coupling device while the tray is in its operating position.

In particular, the fixing device may be formed by a fixing pin and a fixing recess. Preferably, the fixing pin and the fixing recess are complementary to one another, in particular corresponding to a key hole principle. Then, the fixing pin can engage for fixing in the fixing recess.

For example, the fixing pin on the storage plate and the fixing recess may be formed or arranged on the coupling device.

Alternatively, it is conceivable that the fixing pin on the coupling device and the fixing recess are formed or arranged on the tray.

Also, other ways of forming a fixing are conceivable.

For example, the support plate on the coupling device by means of a, preferably releasably releasable, bolt can be fixed to this. It is also conceivable that the fixing device, in particular the fixing pin with the fixing recess, forms a click system. Thus, the tray can be inserted into the coupling recess and then fixed to it by means of fixed click, in particular for use in their operating position.

It is particularly advantageous if the upper and lower coupling arms have different arm lengths. In particular, it may be provided that the upper is shorter than the lower coupling arm. As a result, the tray can be easily guided into the coupling recess or pulled out of it.

It is also conceivable that the coupling recess has at least one bevel, preferably at an angle between 5 ° and 80 °, in particular between 10 ° and 30 ° to the tray in its operating position. This facilitates the removal or the return of the shelf additionally.

It can be provided that the lower coupling arm is designed so that it supports the shelf in its operating position in a support area, preferably outside of its center of gravity, the lower side. In particular, it is conceivable that the storage plate is supported in an end region of the lower coupling arm.

Also, the upper coupling arm may be formed so that it holds the tray in its operating position on the upper side, preferably as an abutment to the lower coupling arm. The lower and the upper coupling arm can thus together hold the tray gravity-clamping. On further fastening devices can be omitted.

It is also conceivable that the support region extends over at least one tenth of the width of the storage plate defined transversely to the longitudinal direction, ie in a transverse direction, of the coupling arms. Thus The coupling device can also secure the shelf against tilting in the transverse direction.

It is also conceivable that the storage tray in its removal position in a minimum removal angle obliquely to the horizontal can be removed. For example, the minimum removal angle may be 10 degrees or more. Then, the tray can still be removed easily, accidental slipping out of the tray in its operating position is effectively prevented.

It can also be provided that a weighing device is provided, which is designed as an attachment, and that the storage plate can be coupled by means of the coupling device to the weighing device. Thus, the tray can be coupled via the weighing device to the disc cutting machine. In addition, the weight of the cut slices can be measured and / or monitored. Thus, the weighing device can be used with a dual function.

Further features and advantages of the invention will become apparent from the following detailed description of embodiments of the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims.

The individual features may be implemented individually for themselves or for a plurality of combinations in variants of the invention. In the schematic drawing embodiments of the invention are shown, which are explained in more detail in the following description.

To facilitate the understanding of the embodiments, the same reference numerals are used for corresponding elements in the figures.

The Fig. 1 shows an electrically operated disc cutting machine 1 for cutting slices of particular stranded Schneidegut with a machine housing 2, which holds in a motor tower 3, a drive motor and driven by the drive motor rotating cutting blade 4 . The slicing machine 1 further has a storage area 5 arranged in the region of the cutting knife 4 with a substantially planar storage shelf 6 for receiving separated slices. The storage plate 6 is connected by means of a coupling device 7 to a Attachment of the machine housing 2 trained weighing device 8 releasably coupled.

The cut material to be cut can be placed on a carriage 9 . For slicing, the carriage 9 can then be moved along the cutting blade 4 parallel to a cutting plane defined by the cutting blade 4.

The Fig. 1 shows a state in which the slicing machine 1 is in a cutting operation. In this cutting operation 4 cut slices can be stored or collected on the tray 6 by the cutting blade. For this purpose, the tray 6 is in its operating position, which is expediently oriented horizontally in this embodiment for collecting the discs. In the operating position, the storage tray 6 is coupled to the coupling device 7.

The coupling device 7 has an upper coupling arm 10 and a lower coupling arm 11 . For this purpose, the coupling device 7 is formed substantially U-shaped. In particular, between the coupling arms 10, 11, a coupling recess 12, which is open on one side, is formed for coupling the depositing plate 6. The coupling recess 12 has a horizontally oriented opening. In this coupling recess 12 - and thus between the two coupling arms 10, 11 - the tray 6 is arranged according to their operating position.

As will be explained in more detail below, the tray 6, in particular relative to the coupling device 7, also be moved in a removal position. In this, it can be the coupling device 7, for example, for cleaning purposes, removed or introduced again into the coupling device.

The Fig. 2 shows the slicing machine 1 of Fig. 1 with its machine housing 2, the motor tower 3, the cutting blade 4, the tray 6, the coupling device 7 and the weighing device 8 in a plan view from above in a highly schematic representation.

In the plan view of Fig. 2 Furthermore, the two coupling arms 10, 11 can be seen, which extend longitudinally along a longitudinal direction L and widthwise along a transverse to the longitudinal direction L oriented width direction B.

The coupling recess 12 formed by the two coupling arms 10, 11 (FIG. Fig. 1 ) is thus formed along the longitudinal direction L. Its one-sided opening is arranged on the side facing away from the weighing device 8 side.

The coupling device 7 and in this preferred embodiment, the coupling arms 10, 11 have along the width direction B to a width p, which is at least one-tenth of the width q of the tray 6. The width q of the tray 6 is again along the width direction B and thus transverse to the longitudinal direction L of the coupling arms 10, 11 to measure. In this embodiment, the width p of the coupling device 7 is at least 20 percent of the width q of the tray 6 on.

In other words, the storage plate 6 is supported along the width of the coupling device 7 and here within a support region 14 on the coupling device 7. In this case, the width of the coupling device 7 and thus the support area 14 extends over at least one tenth of the width of the storage tray. 6

It can also be seen that the coupling device 7 has a holding arm 13 , via which it is connected to the weighing device 8. The load introduction into the weighing device 8 is thus effected via the holding arm 13. The length of the holding arm 13 is selected such that cut-off slices pass properly onto the depositing plate 6 for storage.

The width p of the support portion 14 is chosen wider in this embodiment than the width of the support arm 13. Among other things, characterized in particular by the selection of the width p described above, the tray 6 against rotation about the longitudinal direction L.

The FIGS. 3a, 3b show - also in highly schematic representation - side views of the slicing machine 1 of Fig. 1 , In each case, the coupling device 7 arranged on the weighing device 8 with its coupling arms 10, 11, by which the coupling recess 12 is formed, and the holding arm 13 can be seen. The holding arm 13 acts on a weighing cell 19 of the weighing device 8. The load cell 19 is fastened via a fastening device 18 to the remaining housing of the weighing device 8.

In both figures, the tray 6 is also still visible. In the state according to Fig. 3a is the tray 6 in her Operating condition, whereas the state according to the Fig. 3b the tray 6 shows in its removal position.

The slicing machine 1 has according to the FIGS. 3a and 3b a fixing device for horizontal fixation of the tray in its operating position. The fixing device is formed by a fixing pin 16 and a fixing recess 15. In this embodiment, the fixing recess 15 is formed on the tray 6 on the underside thereof. The fixing pin 16 is arranged on the coupling device 7, in particular on the lower coupling arm 11.

Again Fig. 3a can be removed, engages the fixing pin 16 in the operating position of the tray 6 in the fixing recess 15 a. Thus, the tray 6 is secured by the fixing against a, in particular accidental, shifting in the horizontal direction.

The lower coupling arm 10 is in particular designed such that it supports the deposition plate 6 in its operating position in the support region 14 outside its center of gravity S on the underside. For this purpose, the fixing recess 15 and the fixing pin 16 are positioned correspondingly relative to the lower coupling arm 10.

Further, the upper coupling arm 11 is formed so as to form an abutment for the lower coupling arm 10. For this he holds the shelf 6 in their operating position on the top. Thus, a total gravitational clamping coupling of the tray 6 is achieved within the coupling device 7.

It can be seen that the upper coupling arm 10 along the longitudinal direction L is significantly shorter than the lower coupling arm 11 is formed.

The coupling recess 12 further has two bevels 20, 21. The chamfers 20, 21 are against the tray 6 in its operating position, d. H. in this embodiment, against the horizontal, inclined. In particular, in this embodiment, the angle α, with which the chamfer 21 is inclined against the tray 6 in its operating position, about 25 °.

Like from the Fig. 3b it can be seen, the storage plate 6 is inclined in its removal position with a minimum removal angle β to the horizontal. In this embodiment, the minimum removal angle β substantially corresponds to the angle α. Thus, the tray 6 can be removed by being inclined at least by the minimum removal angle β to the horizontal. Conveniently, moreover, the tray 6 is slightly raised to lead out the fixing pin 16 from the fixing recess 15.

The Fig. 3c Finally shows an alternative embodiment of a slicer according to the invention also in a highly schematic representation in side view. This embodiment largely corresponds to the embodiment of the above FIGS. 1 . 2 . 3a and 3b , It differs essentially in the type of training of fixation.

The disc cutting machine of this embodiment also has a coupling device 7 'with an upper coupling arm 10' and a lower coupling arm 11 '. However, the upper coupling arm 10 'now has on its underside a fixing recess 15' for engaging a fixing pin 16 'arranged on the upper side of a support plate 6' in the operating position of the support plate 6 '.

In these embodiments, the fixing devices each extend over the entire width of the coupling devices. In other alternative embodiments, on the other hand, it is provided that the fixing devices extend over only a part of the width of the coupling device.

Taking a synopsis of all figures of the drawing, the invention in summary relates to an electrically operated disc cutting machine for cutting slices of particular stranded cutting material, preferably food. The slicing machine has, in particular, an improved shelf for storing cut-off slices. In this case, the storage plate, in particular without tools, coupled by means of a coupling device to the disc cutting machine or decoupled from this. The installation or removal of the shelf make it particularly easy. For this purpose, the coupling device has two coupling arms, which form a coupling device. In the coupling device, the tray, in particular gravity clamping, be clamped. In order to avoid lateral slipping out of the tray in its operating position, a fixing device is further formed on the coupling device and on the tray.
