Definitions

  • 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.
  • 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.
  • 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.
  • a multi-track operation is possible, i. Products can be fed in several parallel adjacent tracks of the cutting plane and simultaneously cut.
  • An intermediate sheet feeder is off US Pat. No. 3,019,578 known.
  • 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.
  • the object is achieved with an intermediate sheet feed with the features of claim 1.
  • thickened roller sections are formed on the roller bodies.
  • the roller bodies can each consist of a rubberized shaft.
  • 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.
  • 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.
  • each roller body is coupled via a belt with its own drive.
  • a plurality of, in particular cylindrically shaped, pressure elements are arranged along the counter-roller for pressing the counter-roller against the roller.
  • 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.
  • 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.
  • 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.
  • 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.
  • At least 5 printing elements are provided over the length of the backing roll.
  • at least 10 printing elements are provided over the length of the backing roll.
  • at least 15 printing elements are provided over the length of the backing roll.
  • 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.
  • 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.
  • the rollers can thus be carried by the axle.
  • Such a counter roll can be easily and inexpensively manufactured.
  • 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.
  • the outer circumference of the rollers of the contacting with the roller or between the roller and the counter-roller promoted embourblattbahnmaterials.
  • 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.
  • 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.
  • 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.
  • 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.
  • the axis can return to the initial position when it is no longer subjected to a compressive force.
  • 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.
  • a, in particular pneumatic, pressure chamber 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.
  • 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 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 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.
  • 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.
  • 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.
  • recesses may be provided from which partially projecting on an axis of the counter roller rotatably mounted rollers.
