DESCRIPTION

Intermediate sheet feed

The present invention concerns an intermediate sheet feed for a device for slicing food products, in particular a high power slicer, with at least one driven cylinder and at least one counter cylinder opposite the cylinder for transporting a free end of at least an endless band of an intermediate sheet material between the cylinder and the counter cylinder.

Intermediate sheet feeds of this type, which are also called intermediate sheet feed mechanisms, leaf inserters or interleavers, are basically known to the state of the art.

Sliced cutting devices, which are also called high power slicers, are also known for the state of the art and serve to slice food products, such as sausage, cheese, ham and the like, with a high sequence cutting In such a slicing device a product can be fed to a cutting plane in which, by means of a cutting blade, slices are separated from the front end of the product. In this case, multipath operation is also possible, that is, products can be fed into several paths of the cutting plane that are parallel juxtaposed and these can be sliced simultaneously.

It is also known to provide an intermediate sheet feed in a slicing device. Through the feeding of intermediate sheets, an intermediate sheet is made available between separate product slices.

An intermediate sheet feed is known from US 3 019 578 A. The sliced cutting device shown in Figure 1 of this document has an intermediate sheet feed in which a leading free end of a paper strip is transported paraffin 42 between a driven cylinder 52 and a counter cylinder 50 opposite the cylinder 52 and is then placed behind a cutting plane in which a cutting blade 70 rotates which separates the free end section of the strip of paraffin paper 42 located behind the cutting plane and a slice of a piece of bacon 16. The separate sheet of paraffin paper, together with the slice, falls on a conveyor belt 118 that is below the cutting plane, on which, therefore, it is formed a horizontal stack of slices of bacon with sheets of paper arranged between them. Document US 2012/0073249 discloses an intermediate sheet feed having two correspondingly opposite cylinders and counter cylinders. The cylinders can be operated individually and can rotate around a common axis of rotation. Other intermediate sheet feeds are known, for example, from WO 00/76733 A1, EP 2 543 486 A2 and EP 1 940 685 B1.

The present invention is based on the problem of providing an improved intermediate sheet feed that can be used in conjunction with a slicer to cut slices of food products in several ways. The problem is solved with an intermediate sheet feed with the characteristics of claim 1.

It can be provided that thickened cylinder sections are configured in the cylinder bodies.

The cylinder bodies may consist respectively of a gummed tree.

In addition, it can be provided that each cylinder body is rotatably mounted movably in an outer section by means of a grooved ball bearing, a shaft sealing ring being provided outside the respective grooved ball bearing and an outermost arrangement being provided clamping assembly that makes it possible to fix a drive wheel.

At the inner axial end of each cylinder body, a needle bearing can be provided, a connecting shaft being mounted on the needle bearings through which the two needle bearings are rotatably connected to each other.

Preferably, each cylinder body is coupled with its own drive by means of a belt.

According to an embodiment, it is provided that, in order to press the counter cylinder against the cylinder, a large number of particularly cylindrically shaped pressure elements are arranged along the counter cylinder.

The pressure elements are provided and configured to press the counter cylinder against the cylinder. To do this, each pressure element can move directly or indirectly against the counter cylinder to cause a pressure force on the counter cylinder. Each pressure element can move in this case independently of the other pressure elements. In this case, each pressure element may request the counter-cylinder at a certain location, in which the respective pressure element acts against the counter-cylinder, with the corresponding pressure force that is directed at least with one component in the direction of the cylinder and , in this way, press the counter cylinder against the cylinder. In particular, the pressure elements can press against the counter cylinder with respect to the longitudinal direction of the counter cylinder preferably seen in radial direction, with

what the counter cylinder moves towards the cylinder behind the counter cylinder seen from the pressure elements and, therefore, is pressed against it.

Preferably, the pressure elements are arranged displaced with respect to each other seen in the longitudinal direction of the counter cylinder. The pressure elements can act on the counter cylinder in several defined places to press it against the cylinder. Therefore, thanks to the total length of the counter cylinder, a pressure of at least approximately uniform tightening is achieved. It results in an almost flexible readjustment of the clamping pressure in all operating states.

This at least approximately uniform tightening pressure can advantageously impact on the transport of the intermediate sheet web material since the intermediate sheet web material can also be transported very evenly between the cylinder and the counter cylinder, seen over the entire width of said material.

Preferably, at least 5 pressure elements, more preferably at least 10 pressure elements and even more preferably at least 15 pressure elements over the length of the counter cylinder are provided.

It is especially advantageous if the pressure elements are arranged distributed over the entire length of the counter cylinder, in particular at a uniform distance from one another and / or alternating with respect to a support, for example a roller support. Therefore, a uniform tightening pressure of the counter cylinder in the cylinder over the entire length of the counter cylinder can be achieved in a particularly simple manner.

According to a preferred refinement of the invention, the counter cylinder comprises an axis that particularly defines a longitudinal axis of the counter cylinder, on which a large number of rollers are rotatably disposed, wherein the rollers are arranged along the axis preferably in respective pairs, preferably at a uniform distance, and where the pressure elements are arranged, seen along the axis, alternating between the rollers, in particular on the side of the axis, so that each pressure element can request the axis directly or indirectly With a force of pressure.

Therefore, in the counter cylinder, the rollers can be supported by the shaft. A counter cylinder of this type can be manufactured simply and cheaply. In addition, the use of the large number of rollers offers the advantage that each roller can be configured in a relatively small way, but nonetheless a sufficient contact surface is provided for contacting the cylinder or intermediate sheet material seen. over the entire length of the counter cylinder. In this case, the outer periphery of the rollers is used for contacting the cylinder or the intermediate sheet web material transported between the cylinder and the counter cylinder.

Since the rollers can be configured small and, therefore, kept compact, the counter cylinder can also become relatively compact in general, whereby the counter cylinder can have a small mass or a reduced moment of inertia with respect to a rotational movement. around the longitudinal axis of the axis. This is advantageous in relation to the advance of the free end of the endless band to behind the cutting plane of a sliced cutting device, since, in this context, it may happen that the free end has to accelerate strongly and, for therefore, it certainly has to be thrown up behind the cutting plane at an instant exactly in tune with the cutting process, then the corresponding acceleration rolls undergo the counter-cylinder rollers.

Preferably, at least 5 rollers, more preferably at least 10 rollers, still more preferably at least 20 rollers and still more preferably at least 30 rollers on the shaft are arranged.

Since the counter cylinder can be configured compact, its dimensions, particularly transversely to the longitudinal axis of the axis, can be kept small. Therefore, the counter cylinder needs a relatively small structural space and, consequently, can be arranged, in particular in combination with the cylinder, relatively close to the cutting plane of a slicing device. Therefore, the sliding path that extends between the intermediate sheet feed and the cutting plane for the free end of the intermediate sheet material can be kept short. Therefore, it is a clear improvement over the solutions known so far.

The shaft can be configured from an elongated cylindrical body with small diameter. Therefore, weight can be saved. The diameter of the shaft can be, for example, at least about 6 mm. Thanks to the small diameter, a local deformation or warping of the shaft may be possible, whereby stability can be improved and a local adaptation of the pressure forces may be possible.

The shaft can be configured of a plastic material. The rollers can also be configured of plastic. Therefore, the weight and correspondingly the moment of inertia of the counter cylinder can be reduced further.

Each roller can be configured as a combination with an integrated ball bearing or as a bearing, which has an inner ring connected with the shaft and an outer ring arranged movable on balls in the inner ring, whose outer periphery corresponds to the outer periphery of the respective roller that comes into contact with the cylinder or intermediate sheet material.

According to a preferred configuration of the invention, the shaft is flexibly deformable. Therefore, the shaft can be warped or elastically deformed when requested with a respective force of pressure by the pressure elements arranged laterally next to the axis and displaced relative to each other seen in the longitudinal direction of the axis to compensate, for example, for a fault. of flatness in the area between the cylinder and the counter cylinder. In this case, the shaft can return to the starting position when it is no longer requested with a pressure force. By using such an axle, an especially uniform tightening pressure can be achieved between the cylinder and the counter cylinder.

Preferably, each pressure element, in particular on its side away from the counter cylinder, can be requested with a particularly pneumatic pressure force, the respective pressure element transmitting the pressure force directly or indirectly to the counter cylinder. Therefore, the pressure elements can be pneumatically operated to press the counter cylinder against the cylinder.

According to a preferred refinement of the invention, an especially pneumatic pressure chamber is provided that extends at least approximately parallel to the counter cylinder, each pressure element being disposed mobile in a pressure chamber wall that runs between the counter cylinder and the pressure chamber, in particular so that one side of each pressure element away from the counter cylinder is in the pressure chamber. In this way, the pressure elements can be requested with a particularly simple pressure force, in particular pneumatically, by means of the pressure chamber, which can transmit said force to the counter cylinder directly or indirectly to press it against the cylinder.

The pressure force F caused on a pressure element is, in this case, especially dependent on the surface A on the side of the pressure element that penetrates the pressure chamber and the pneumatic pressure P in the pressure chamber according to the equation generally known P = F / A.

Thanks to the regulation of the pressure P in the pressure chamber, the pressure force can be adjusted and, correspondingly, the clamping pressure, transmitted by the pressure elements to the counter cylinder with which the counter cylinder is pressed against the cylinder.

The pressure chamber can have an inlet to connect a compressed air supply. The pressure chamber can also have an outlet that can be provided to connect a compressed air duct to request at least one interlocking element, in particular a locking bolt with compressed air. The interlocking bolt can be operated by means of the compressed air duct connected to the outlet.

The pressure chamber is preferably arranged behind the counter cylinder, seen from the cylinder. In this way, the necessary mounting space for the pressure chamber, the counter-cylinder and the cylinder in an intermediate sheet feed can be kept compact, whereby the intermediate sheet feed can generally be configured compact and therefore arranged close of a cutting edge of a slicing device.

According to a preferred configuration of the invention, the pressure chamber and the counter cylinder are housed in a common housing, in particular a so-called counterpressure mechanism.

The cylinder can be housed in another housing, in particular a so-called waste mechanism.

The common housing of the pressure chamber and the counter cylinder can be applied, in particular, to be loosely attached to the cylinder housing. Therefore, the backpressure mechanism can be caught in the waste mechanism.

Preferably, at least one interlocking element is provided, especially an interlocking bolt, in particular pneumatically requested, by means of which the common housing of the counter cylinder and the pressure chamber can be fixed to the cylinder housing. Therefore, it can be ensured that the back pressure mechanism cannot perform any deviation movement configured as usual when the counter cylinder housed in the back pressure mechanism is pressed by means of the pressure elements against the cylinder housed in the waste mechanism.

In the common housing, in particular in a panel detachably fixed in the common housing, recesses can be provided, of which rollers partially rotatably protrude on a counter-cylinder axis. Therefore, except for the rollers, whose outer surfaces form a contact surface for the counter cylinder contact or the intermediate sheet material web, the counter cylinder may be hidden by the panel.

According to the invention, the cylinder has at least two individually operable cylinder bodies. Such a cylinder is especially suitable for transporting intermediate sheets in at least two juxtaposed tracks by means of a respective cylinder body, for example in conjunction with a slicer to cut slices of food products in several ways.

The cylinder bodies can be movably connected to each other by means of a bearing in the central zone. Therefore, the cylinder bodies can be arranged immediately juxtaposed, whereby the length of the cylinder can be kept short. In addition, it can be ensured that the cylinder bodies can rotate independently of each other. Thus, an individual track drive of the interleaver 5 intermediate blades feed and individual track guidance of the interleaver blade sheet in an immediate ejection zone is made possible.

US 2012/0073249 A1 shows an interleaver of the type mentioned here. However, the two cylinders shown here are not movably connected to each other by means of a bearing in the central zone.

The invention also concerns a device for slicing food products, in particular high power slicer, comprising an intermediate sheet feed according to the invention, a product support and at least one cutting blade that rotates in a plane of cutting to separate slices of at least one product supplied on the product support, the feeding of intermediate sheets being provided to transport a free end of an endless band up to a leading end of the product support to provide an intermediate sheet between slices cut.

15 The slicing device can be specially configured for slicing food products in several ways. In this case, products can be fed to the cutting plane in at least two ways and the intermediate sheet feed can be provided to provide in each way a free end of an endless band before the leading end of the product support.

Next, the invention is described by way of example with the help of an advantageous embodiment with reference to the attached drawings. They show, respectively schematically,

Figure 8, a cross-sectional view of a cylinder of the waste mechanism of Figure 4.

The embodiment described below by way of example of an intermediate sheet feed according to the invention comprises a back pressure mechanism 11 described with reference to Figures 1 to 3 and a waste mechanism 13 described with reference to Figures 4 a 8. As described in more detail below, the backpressure mechanism 11 can be attached to the waste mechanism 13 and then fixed. In this case, a cylinder 15 disposed in the waste mechanism 13 and a counter cylinder 17 disposed in the counterpressure mechanism 11 are arranged opposite each other with their longitudinal axes 40 oriented in substantially parallel directions to each other. In the counterpressure mechanism 11, a large number of pressure elements 39 that can be applied with pneumatic pressure are arranged along the counter-cylinder 17. In this case, the pressure elements 39 are arranged laterally next to the counter-cylinder 17 and displaced relative to each other in the longitudinal direction of the counter-cylinder 17. By means of the pressure elements 39, the counter-cylinder 17 can be pressed against the cylinder 15, achieving a very uniform clamping pressure 45 of the counter cylinder 17 against the cylinder 15 in particular seen over the entire length of the counter cylinder 17.

The counter cylinder 17 is disposed in a housing 19 of the counterpressure mechanism 11 and has an elongated shaft 23 (see Figure 3) defining a longitudinal axis 21 of the counter cylinder 17 and which is conceived as flexibly deformable or flexibly curved. When the counter-cylinder 17 is pressed against the cylinder 15, the axis 23, due to its elasticity, can compensate, for example, irregularities in the pressure distribution and can then adopt, for example, a wavy path. Therefore, by means of the elastic deformation of the shaft 23, in combination with the large number of pressure elements 39, an especially uniform clamping pressure of the counter cylinder 17 against the cylinder 15 can be achieved.

A large number of rollers 25 are arranged on the axis 23 where, in the example depicting, a total of thirty-four rollers are provided. Each roller 25 is formed by a grooved ball bearing whose inner ring 27 is

fixedly connected with the shaft 23, while the outer ring 29 is disposed with respect to the inner ring 27 in a manner known per se by means of rolling bodies 31 formed by balls and rotating with respect to the inner ring 27.

As shown in Figure 3, the rollers 25 are preferably arranged in respective pairs displaced relative to each other at a uniform distance along the axis 23. In this case, between the rollers 25 of a respective pair of rollers a respective narrow spacer disc 53 to keep the pair of rollers at a fixed distance from each other. In addition, a hexagonal nut 55 is provided for mounting the shaft 23 in the housing 19 on an axial end of the shaft 23, while a safety ring 57 is arranged on the other axial end of the shaft 23 as shown in Figure 3.

On the outer side of the housing 19 a panel 33 is screwed, behind which the counter-cylinder 17 is arranged. As shown in Figures 1 and 2, in the panel 33 are formed recesses 35 that are sized and spaced apart from each other in such a way. so that the outer surfaces of the outer rings 29 of the ball bearing 25 can run outwardly through the recesses 35 to contact corresponding thickened sections 75 provided in the cylinder 15 or with a band of intermediate sheet material transported between the rings 29 and thickened sections 75. The thickened sections 75 of the cylinder 15 in this case also protrude from the recesses of a panel 77, behind which the cylinder 15 is arranged in a housing 69 of the waste mechanism 13.

The axis 23 is arranged mobile in a driving direction B which runs, as shown in Figure 3, in radial direction with respect to the longitudinal axis 21 of the axis 23. In a movement of the axis 23 in the driving direction B, the counter-cylinder 17 moves in the intermediate sheet feed against the cylinder 15, the driving direction B running radially with respect to the longitudinal axis 37 of the cylinder 15.

As mentioned, to press the counter-cylinder 17 against the cylinder 15, a large number of pressure elements 39 configured in the form of a cylinder or plunger are provided. As Figure 3 shows, the pressure elements 39 are between the rollers 25 laterally next to the axis 23 and are in this case distributed substantially over the entire length of the axis 23 and arranged at a uniform distance from each other.

In this case, the front side 41 of each pressure element is turned towards the axis 23 and is particularly applied to the outer side of a spacer ring 49, which is particularly provided between pairs of adjacent rollers to keep these at a defined distance of one in relation to another. In addition, the rear side 43 away from the axis 23 of each pressure element 39 penetrates a pressure chamber 45 on whose wall 47 the pressure elements 39 are movably disposed in the driving direction B. To seal the pressure chamber 45, each pressure element 39 is provided with a sealing ring 51 that surrounds the respective pressure element 39 in peripheral direction as shown in Figure 3.

The pressure chamber 45 has an inlet 59 to which a compressed air duct can be connected to supply compressed air. In the housing 19 a bolt 63 is arranged on each of the two front sides. Thanks to the introduction of bolts 63 in housings 65 provided in the waste mechanism 13, the back pressure mechanism 11 engages the waste mechanism 13.

In the waste mechanism 13, two locking bolts not shown are also provided, where a respective locking bolt can fit into a countersink 67 provided on each front side of the housing 19 to lock the back pressure mechanism 11 into the waste mechanism. 13. Alternatively, on each front side of the counterpressure mechanism 11, a corresponding locking bolt can be provided that can fit into an associated countersink in the waste mechanism 13 (not shown).

The interlocking bolts can be manually adjusted from a release position in which they do not fit in the countersinks 67, to an interlocked position and, preferably, can also be embedded there. In the interlocking position the interlocking bolts fit the countersinks 67 to fix the back pressure mechanism 11 in the waste mechanism 13.

The pressure chamber 45 has an outlet 61 to which a compressed air duct not shown can be connected, through which compressed air can be provided for pneumatic solicitation of the locking bolts. After the interlocking bolts have been manually placed in the interlocking position and, preferably also, they have been embedded, the interlocking bolts can be ordered with compressed air through the compressed air conduit to secure them in the interlocked position. In this case, the compressed air line connected to the outlet 61 acts in a certain way only as an extension of the pressure chamber 45 without there being a relevant loss of pressure.

The cylinder 15 has two cylinder bodies 71a, 71b which, as shown in Figure 6, are juxtaposed, so that they can rotate around a common axis of rotation 73 and in which the thickened cylinder sections 75 shown in the Figure 8. The cylinder bodies 71a, 71b consist, for example, respectively of a gummed shaft, so that they have a strong grip surface, which is advantageous for transporting the web of intermediate sheet material.

Each cylinder body 71a, 71b is rotatably disposed in an outer section by means of a grooved ball bearing 79. Outside the respective grooved ball bearing 79, a shaft sealing ring 81 is provided. Still further, it is provided in the outside a clamping assembly 83 which makes it possible to fix a drive wheel.

5 At the axial inner end of each cylinder body 71a, 71b a needle bearing 85 is provided. In the needle bearing 85 there is arranged a connecting shaft 87 through which the two bodies are rotatably connected to each other. of cylinder 71a, 71b. Each cylinder body 71a, 71b is coupled with its own drive by means of a belt 89, in particular a toothed or trapezoidal belt (see Figures 4, 5 and 7), so that each cylinder body 71a, 71b can be operated individually. Therefore, the embodiment described herein 10 of an intermediate sheet feed according to the invention can be used, in particular for a dual track drive to individually provide intermediate sheets to each track of a slicer working in two tracks. Correspondingly, for operation in N tracks (N = 1, 2, 3, 4), the cylinder 15 materializes with N cylinder bodies.

For the operation of the intermediate sheet feed mechanism, the counterpressure mechanism 11 engages the waste mechanism 13 and the pressure chamber 45 is requested with compressed air. Therefore, by means of the outlet 61 and a compressed air duct connected thereto, the interlocking bolts are secured in the interlocking position, so that they fit into the countersinks 67 in the housing 19 and fix the back pressure mechanism 11 to the waste mechanism 13.

Thanks to the pneumatic pressure in the pressure chamber 45, the pressure elements 39 are requested with pressure and 20 are pressed in driving direction B against the counter-cylinder 17 which, again, moves from the pressure elements 39 also in the direction of actuation B against the cylinder 15 and, therefore, is pressed against the cylinder 15. By means of the pressure regulation in the pressure chamber 45, the tightening pressure of the counter-cylinder 17 in the cylinder 15 can be regulated and used in this case Due to the large number of pressure elements 39 that are arranged distributed over the entire length of the counter-cylinder 17 next to the counter-cylinder 17 and can cause a pressure force on it, and due to the flexible or elastically deformable configuration of the axis 23 can a very uniform tightening pressure is achieved seen over the entire length of the counter cylinder 17 which is caused by the counter cylinder 17 on the c ilindro 15.
