Description

The present invention relates to an inter-sheet feeder for a device for slicing food products, especially high-performance slicers, comprising at least one driven roller and at least one counter-roller opposing the roller for conveying a free end of at least one continuous web of inter-sheet material between the roller and the counter-roller.

Such intermediate sheet feeds, which are also referred to as Zwischenblattzuführeinrichtungen, sheet inserter or interleaver, are basically known in the art.

Slicers, also referred to as high performance slicers, are also known in the art and serve to cut up food products such as sausage, cheese, ham, and the like, with a high cut rate. In such a slicing device, a product can be fed to a cutting plane in which slices are separated from the front end of the product by means of a cutting knife. In this case, a multi-track operation is possible, i. Products can be fed in several parallel adjacent tracks of the cutting plane and simultaneously cut.

It is also known to provide an intermediate sheet feeder in a slicing apparatus. By the Zwischenblattzuführung the provision of an intermediate sheet between separated product slices takes place.

An intermediate sheet feeder is off US Pat. No. 3,019,578 known. In the Fig. 1 This cutting apparatus shown in this document has an intermediate sheet feeder in which a front, free end of a wax paper strip 42 between a driven roller 52 and the roller 52 opposite counter roller 50 is conveyed and thereby brought behind a cutting plane in which a cutting blade 70 rotates, which surrounds the behind the cutting plane portion of the free end of the wax paper strip 42 and a disc of a Specklaib 16 separates. The severed wax paper sheet, together with the disk, falls onto a conveyor belt 118 below the cutting plane, thus forming a horizontal stack of bacon slices with paper sheets therebetween. US 2012/0073249 discloses an intermediate sheet feeder having two rolls and corresponding opposite counter rolls. The rollers are individually drivable and can rotate about a common axis of rotation. Other intermediate sheet feeders are for example off WO 00/76733 A1 . EP 2 543 486 A2 and EP 1 940 685 B1 known.

It is an object of the present invention to provide an improved interleaf feeder which can be used in conjunction with a slicer for multi-slicing food products. The object is achieved with an intermediate sheet feed with the features of claim 1.

It can be provided that thickened roller sections are formed on the roller bodies.

The roller bodies can each consist of a rubberized shaft.

Furthermore, it can be provided that each roller body is rotatably mounted on an outer portion via a deep groove ball bearing, wherein outside the respective deep groove ball bearing a shaft seal and even further outside a clamping set is provided which allows the attachment of a drive wheel.

At the axially inner end of each roller body, a needle bearing may be provided, wherein in the needle bearings, a connection axis is mounted, via which the two needle bearings are rotatably connected to each other.

Preferably, each roller body is coupled via a belt with its own drive.

According to one embodiment, it is provided that a plurality of, in particular cylindrically shaped, pressure elements are arranged along the counter-roller for pressing the counter-roller against the roller.

The pressure elements are provided and designed to press the counter roll against the roller. For this purpose, each pressure element is preferably movable directly or indirectly against the counter-roller to cause a compressive force on the counter-roller. Each printing element can be moved independently of the other printing elements. Each pressure element can act on the counter-roller at a certain point at which the respective pressure element acts against the counter-roller, with the respective pressure force which is directed at least with a component in the direction of the roller, and in this way press the counter-roller against the roller. In particular, viewed in relation to the longitudinal direction of the counter-roller, the pressure elements can preferably press in the radial direction against the counter-roller, as a result of which the counter-roller is in contact with the counter roller Pressure elements seen from behind the counter roll lying roller moves and thus pressed against this.

Preferably, the pressure elements are arranged offset in the longitudinal direction of the counter-roller to each other. The pressure elements can act on the counter-roller at several defined locations in order to press it against the roller. As a result, an at least approximately uniform contact pressure is achieved over the entire length of the counter-roller. This results in a quasi-flexible readjustment of the contact pressure in all operating conditions.

This at least approximately uniform contact pressure can have an advantageous effect on the conveyance of the intermediate sheet material, since the intermediate sheet material over its entire width can also be conveyed very evenly between the roll and the counter roll.

Preferably, at least 5 printing elements, more preferably at least 10 printing elements and even more preferably at least 15 printing elements are provided over the length of the backing roll.

It is particularly advantageous if the pressure elements are distributed over the entire length of the counter-roller, in particular at a uniform distance from one another and / or arranged alternately to a bearing, for example a bearing of rollers. As a result, it is particularly easy to achieve a uniform contact pressure of the counter-roller against the roller over the entire length of the counter-roller.

According to a preferred embodiment of the invention, the counter-roller comprises a, in particular a longitudinal axis of the counter-roller defining axis on which a plurality of rollers are rotatably mounted, wherein the rollers, preferably in pairs, preferably at a uniform distance along the axis are seen, and wherein the pressure elements along the axis seen alternately between the rollers, in particular laterally adjacent to the axis, are arranged such that each pressure element can act on the axis directly or indirectly with a compressive force.

In the counter roll, the rollers can thus be carried by the axle. Such a counter roll can be easily and inexpensively manufactured. In addition, the use of the plurality of rollers offers the advantage that each roller can be made relatively small, but overall, over the entire length of the counter-roller, a sufficient contact surface for contacting the roller or the intermediate sheet material is provided. In this case, the outer circumference of the rollers of the contacting with the roller or between the roller and the counter-roller promoted Zwischenblattbahnmaterials.

Since the rollers can be made small and thus kept compact, and the counter roller can be constructed relatively compact overall, which can be achieved that the counter-roller has a low mass or a low moment of inertia against a rotational movement about the longitudinal axis of the axis. This is in connection with the advancement of the free end of the continuous web behind the cutting plane of a slicing advantageous because it may happen in this context that the free end greatly accelerated and thus effectively shot at a precisely matched to the cutting process time behind the cutting plane must, in which case the rollers of the counter-roller experience the corresponding acceleration.

Preferably, at least 5 rolls, more preferably at least 10 rolls, even more preferably at least 20 rolls and even more preferably at least 30 rolls are arranged on the axis.

Since the backing roll can be made compact, the dimensions, in particular transversely to the longitudinal axis of the axis, can be kept small. The counter-roller thus requires a relatively small space and can therefore, in particular in combination with the roller, be arranged relatively close to the cutting plane of a slicing device. As a result, the sliding path for the free end of the intermediate sheet material extending between the intermediate sheet feed and the cutting plane can be kept short. This results in a significant improvement over the previously known solutions.

The axle may be formed of an elongated cylindrical body of small diameter. This can save weight. The diameter of the axle may be, for example, at least approximately 6 mm. Due to the small diameter local deformation or bending of the axis may be possible, whereby the stability can be improved and a local adjustment of the compressive forces may be possible.

The axis may be formed of a plastic material. The rollers can also be made of plastic. As a result, the weight and, correspondingly, the moment of inertia of the mating roll can be further reduced.

Each roller may be formed as a combination with an integrated ball bearing or as a roller bearing having an inner ring connected to the axis and a ring on the inner ring movably mounted outer ring, the outer periphery of the reaching in contact with the roller or the intermediate sheet material outer periphery of the respective role equivalent.

According to a preferred embodiment of the invention, the axis is designed resiliently deformable. The axis can therefore bend or elastically deform, when viewed from the laterally adjacent to the axis and viewed in the longitudinal direction of the axis offset from each other arranged pressure elements, each with a compressive force, for example, to compensate for unevenness in the region between the roller and the counter-roller. In this case, the axis can return to the initial position when it is no longer subjected to a compressive force. By using such an axis, a particularly uniform contact pressure between the roller and the counter-roller can be achieved.

Preferably, each pressure element, in particular on its side facing away from the backing roll side, with a, in particular pneumatic, compressive force can be acted upon, wherein the respective pressure element transmits the pressure force directly or indirectly to the counter roll. The pressure elements can thus be pneumatically operated to press the counter roll against the roller.

According to a preferred embodiment of the invention, a, in particular pneumatic, pressure chamber is provided, which extends at least approximately parallel to the counter roll, each pressure element is movably disposed in a running between the backing roll and the pressure chamber pressure chamber wall, in particular such that one facing away from the backing roll Side of each pressure element in the pressure chamber is located. In this way, the printing elements can be particularly simple, in particular pneumatically, are acted upon via the pressure chamber with a compressive force that they can transmit directly or indirectly to the counter-roller to press them against the roller.

The pressure force F exerted on a pressure element is in particular dependent on the area A of the side of the pressure element projecting into the pressure chamber and the pneumatic pressure P in the pressure chamber according to the generally known equation P = F / A.

By adjusting the pressure P in the pressure chamber, the compressive force transmitted by the pressure elements to the counter-roller and corresponding to the contact pressure with which the counter-roller is pressed against the roller can be adjusted.

The pressure chamber may have an inlet for connecting a compressed air supply. The pressure chamber may also have an outlet, which may be provided for connecting a compressed air line for acting on at least one locking element, in particular a locking bolt with compressed air. The locking bolt can be actuated via the compressed air line connected to the outlet.

The pressure chamber is preferably arranged behind the counter-roller, as viewed from the roller. In this way, the space required for the pressure chamber, backing roll and roll in an intermediate sheet feeder can be kept compact, whereby the intermediate sheet feeder can be made compact overall and thus arranged close to a cutting edge of a slicing device.

According to a preferred embodiment of the invention, the pressure chamber and the counter-roller in a common housing, in particular a so-called counter-pressure device, housed.

The roller can be accommodated in a further housing, in particular a so-called reject device.

The common housing of the pressure chamber and the counter-roller can be releasably attachable to the housing of the roller, in particular be suspended. The counter-pressure device can thus be hooked into the reject device.

Preferably, at least one, in particular pneumatically acted upon, locking element, in particular a locking bolt, is provided, by means of which the common housing of the counter-roller and the pressure chamber can be fixed to the housing of the roller. It can thus be ensured that the counter-pressure device can not carry out any deflection movement, however configured, when the counter-roller accommodated in the counterpressure device is pressed against the roller accommodated in the ejection device by means of the pressure elements.

In the common housing, in particular in a removably attached to the common housing aperture, recesses may be provided from which partially projecting on an axis of the counter roller rotatably mounted rollers. Except for the rollers, the outer surfaces of which form a contact surface for contacting the counter roller or the intermediate sheet material web, the counter roller can thus be covered by the diaphragm.

According to the invention, the roller has at least two individually drivable roller bodies. Such a roller is particularly suitable for conveying intermediate sheets in at least two juxtaposed tracks by means of in each case one roller body, for example in conjunction with a slicer for multi-lane slicing of food products.

The roller bodies are movably connected to one another via a bearing in the middle region. As a result, the roller bodies can be arranged directly next to each other, whereby the length of the roller can be kept short. In addition, it can be ensured that the roller bodies can rotate independently of each other. As a result, a track-individual drive of the interleaver intermediate sheet feed and a track-specific guidance of the interleaver intermediate sheet material web in the immediate ejection region are made possible.

An interleaver of the type in question shows US 2012/0073249 A1 , However, the two rollers shown there are not connected to each other via a bearing in the central region movable.

The invention also relates to a device for slicing food products, in particular high-performance slicers, comprising an intermediate sheet feeder according to the invention, a product support and at least one cutting knife circulating in a cutting plane for cutting off slices of at least one product supplied on the product support, the interleaf feeder being provided for this purpose Promote free end of a continuous web in front of a front end of the product support to provide an intermediate sheet between cut slices.

The slicing device can be designed, in particular, for slicing food products in multiple lanes. In this case, the cutting plane can be supplied in at least two tracks of products and the intermediate sheet feeder can be provided to provide track-individually in each lane a free end of a continuous web before the front end of the product support.

The embodiment of an intermediate sheet feeder according to the invention which is described below by way of example comprises one with reference to FIGS Fig. 1 to 3 described counter-pressure device 11 and a reference to the Fig. 4 to 8 As described later in more detail, the counter-pressure device 11 can be mounted on the reject device 13 and then fixed. In this case, a roller 15 arranged in the ejection device 13 and a counter-roller 17 arranged in the counter-pressure device 11 are located opposite one another with longitudinal axes aligned substantially parallel to one another. In the counter-pressure device 11, a plurality of pressurizable with a pneumatic pressure elements 39 along the counter-roller 17 are arranged. The pressure elements 39 are arranged laterally next to the counter-roller 17 and seen in the longitudinal direction of the counter-roller 17 offset from one another. By means of the pressure elements 39, the counter-roller 17 can be pressed against the roller 15, wherein in particular over the entire length of the counter-roller 17 seen a very uniform contact pressure of the counter-roller 17 is achieved to the roller 15.

The counter-roller 17 is arranged in a housing 19 of the counter-pressure device 11 and has an elongated, a longitudinal axis 21 of the counter-roller 17 defining axis 23 (see. Fig. 3 ), which is resiliently deformable or yielding flexible formed. If the counter-roller 17 is pressed against the roller 15, the axis 23 can balance, for example due to their elasticity, irregularities in the pressure distribution, taking, for example, a wave-shaped course. Due to the elastic deformation of the axis 23, therefore, a particularly uniform contact pressure of the counter-roller 17 on the roller 15 can be achieved in combination with the multiplicity of pressure elements 39.

On the axis 23 a plurality of rollers 25 is arranged, wherein in the illustrated example a total of thirty-four rollers are provided. Each roller 25 is formed by a deep groove ball bearing, the inner ring 27 is fixedly connected to the axis 23, while the outer ring 29 relative to the inner ring 27 is rotatably supported relative to the inner ring 27 in a conventional manner by means of rolling elements 31 formed by balls.

As the Fig. 3 shows, the rollers 25, preferably in pairs, at a uniform distance from each other along the axis 23 are arranged. In this case, in each case a narrow spacer 53 is disposed between the rollers 25 of each pair of rollers to keep the pair of rollers at a fixed distance from each other. Further, a hex nut 55 is provided for supporting the axis 23 in the housing 19 at one axial end of the axis 23, while at the other axial end of the axis 23, a securing ring 57 is arranged, such as Fig. 3 shows.

On the outside of the housing 19, a diaphragm 33 is screwed, behind which the counter-roller 17 is arranged. As the Fig. 1 and 2 show recesses 35 are formed in the aperture 33, which are dimensioned and spaced from each other so that the outer surfaces 29 of the outer race 29 of the ball bearing 25 through the recesses 35 can run out through to corresponding to the roller 15 provided thickened portions 75 and to contact an intermediate sheet material web conveyed between the outer rings 29 and the thickened portions 75. The thickened portions 75 of the roller 15 also emerge from recesses of a diaphragm 77, behind which the roller 15 is arranged in a housing 69 of the reject device 13.

The axis 23 is movably mounted in an actuating direction B, the - like Fig. 3 shows - in the radial direction to the longitudinal axis 21 of the axis 23 extends. In a movement of the axis 23 in the direction of actuation B, the counter-roller 17 is moved in the intermediate sheet feed against the roller 15, wherein the actuating direction B extends in the radial direction to the longitudinal axis 37 of the roller 15.

As mentioned, a plurality of cylinder-shaped or piston-shaped pressure elements 39 is provided for pressing the counter-roller 17 against the roller 15. As Fig. 3 shows, the pressure elements 39 between the rollers 25 are laterally in addition to the axis 23 and are 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 of the axis 23 faces and lies in particular on the outside of a spacer ring 49 which is provided in particular between adjacent pairs of rollers in order to keep them at a defined distance relative to each other. In addition, the rear side 43, facing away from the axis 23, of each pressure element 39 projects into a pressure chamber 45 into whose wall 47 the pressure elements 39 are movably mounted in the direction of actuation B. For sealing the pressure chamber 45, each pressure element 39 is provided with a sealing ring 51 which surrounds the respective pressure element 39 in the circumferential direction, such as Fig. 3 shows.

The pressure chamber 45 has an inlet 59, to which a compressed air line for supplying compressed air can be connected. On the housing 19, a bolt 63 is arranged on each of the two end faces. By introducing the bolts 63 in provided on the Ausschusseinrichtung 13 receptacles 65, the counter-pressure device 11 is mounted on the reject device 13.

On the reject device 13, two locking bolts, not shown, are also provided, each one locking bolt can engage in a provided on each end face of the housing 19 depression 67 to lock the counter-pressure device 11 to the reject device 13. Alternatively, a corresponding locking bolt can be provided on each end face of the counter-pressure device 11, which can engage in an associated depression on the reject device 13 (not shown).

The locking bolts can be moved manually from a release position in which they do not engage in the depressions 67, in a locking position and preferably also engaged. In the locking position, the Locking pin in the depressions 67 a to fix the counter-pressure device 11 to the reject device 13.

The pressure chamber 45 has an outlet 61, to which a compressed air line, not shown, can be connected, can be provided via the compressed air for pneumatic actuation of the locking bolt. After the locking bolts have been manually brought into the locking position and preferably also engaged, the locking bolts can be acted upon via the compressed air line with compressed air to secure it in the locked position. In this case, the compressed air line connected to the outlet 61 acts to some extent only as an extension of the pressure chamber 45, without there a relevant pressure loss occurs.

The roller 15 has two roller bodies 71a, 71b, which are like Fig. 6 shown juxtaposed so that they can rotate about a common axis of rotation 73 and where the in Fig. 8 shown thickened roller sections 75 are formed. For example, the roller bodies 71a, 71b each consist of a rubberized shaft, so that they have a non-slip surface, which is advantageous for conveying the intermediate sheet material web.

Each roller body 71a, 71b is rotatably mounted on an outer portion via a deep groove ball bearing 79. Outside the respective deep groove ball bearing 79, a shaft seal 81 is provided. Still further outside a clamping set 83 is provided, which allows the attachment of a drive wheel.

At the axially inner end of each roller body 71a, 71b, a needle bearing 85 is provided. In the needle bearings 85, a connecting shaft 87 is mounted, via which the two roller bodies 71a, 71b are rotatably connected to each other. Each roller body 71a, 71b is coupled via a belt 89, in particular a toothed or V-belt, with its own drive (cf. Fig. 4, 5 and 7 ), so each roller body 71a, 71b is individually drivable. The embodiment of an intermediate sheet feeder according to the invention described here can thus be used in particular for a double-track operation in order to provide individual sheets for each track of a two-line slicer. Accordingly, for operation in N tracks (N = 1, 2, 3, 4,), the roller 15 is realized with N roller bodies.

To start the Zwischenblattzuführeinrichtung the counter-pressure device 11 is mounted on the reject device 13 and the pressure chamber 45 is acted upon with compressed air. As a result, the locking bolts are secured in the locking position via the outlet 61 and a compressed air line connected thereto, so that they engage in the depressions 67 on the housing 19 and fix the counter-pressure device 11 to the reject device 13.

By the pneumatic pressure in the pressure chamber 45, the pressure elements 39 are pressurized and pressed in the direction of actuation B against the counter roll 17, which in turn is also moved by the pressure elements 39 in the direction of actuation B against the roller 15 and thus pressed against the roller 15. By adjusting the pressure in the pressure chamber 45 while the contact pressure of the backing roll 17 can be adjusted or adjusted to the roller 15. Due to the plurality of pressure elements 39, which are arranged distributed over the entire length of the counter-roller 17 laterally adjacent to the counter-roller 17 and can cause a compressive force on this, and the flexible or yieldingly deformable configuration of the axis 23 can over the entire length of the counter-roller 17 seen very uniform contact pressure, the counter roller 17 causes the roller 15 can be achieved.
