Definitions

  • the invention relates to a device for providing web-shaped interleaf material in a cutting area, in which supplied products are cut into slices and interleaves are introduced, which are separated from the interleaved material provided in the cutting area.
  • slices separated from the products can consequently be provided with the interleaves introduced in the cutting area.
  • interleaves can be inserted between two immediately successive panes or interleaves can be inserted under a pane and thus between this pane and a support surface of this pane.
  • portions from several slices for example, there is then an intermediate sheet under the bottom slice of a portion.
  • Such a function which is also referred to as the underleaver function, does not exclude the fact that when portions are formed, an interleaf not only lies under the bottom slice, but one or more interleaves are also inserted between two consecutive slices within the portion become.
  • an interleaf can generally be inserted within a portion either between each pair of directly consecutive slices or only between one or more pairs of directly consecutive slices, e.g. between every nth pair, where n> 1.
  • interleavers Such devices are known in principle in the field of slicing food products and are also referred to as interleavers or underleavers.
  • an interleaver can also exercise an underleaver function, and vice versa.
  • the present disclosure therefore applies not only to the interleavers primarily explained here or the provision of interleaves or interleaf material between two immediately successive disks, but also to so-called "underleavers" which are used to place a sheet under products. With such a bottom sheet feed it is ensured that the products at least do not rest with their entire underside directly on a support surface, for example a conveyor device.
  • interleaver is also an underleaver, and vice versa.
  • the invention also relates to a device for slicing food products with a product feed, which feeds products to be sliced to a cutting area in which a cutting knife moves in a rotating and / or revolving manner in order to cut the fed products into slices, and with an inventive inter- or Underleaver.
  • Such cutting devices are also referred to as slicers or high-speed slicers, the latter against the background that with such machines, for example, bar or loaf-shaped food products can be sliced at high cutting speeds of several hundred to several thousand slices per minute.
  • the separated, For example, stacked or shingled portions are formed on a storage surface formed, for example, by a portioning belt.
  • An interleaver is used, for example, to insert interleaves between consecutive slices of a portion so that the slices can later be separated from one another more easily.
  • paper or a plastic film is used as the material for the interleaves.
  • interleavers and underleavers are also subject to ever higher demands.
  • Known interleaver or underleaver concepts which generally deliver satisfactory results, often no longer meet these increased requirements.
  • a problem with the known interleavers or underleavers is that the ejection of the material web into the cutting area is a highly dynamic process which is more difficult to handle the greater the cutting speed. Therefore, this highly dynamic ejection must be decoupled from the removal of the material web from the relatively sluggish material supply, so that a sufficiently long material web length is always available outside the material supply and the material to be ejected does not have to be taken directly from the material supply, such as a roll of material.
  • the object of the invention is to improve an interleaver in such a way that a trouble-free provision of web-shaped interleaf material at a cutting area is guaranteed and, in particular, to ensure controlled loop formation.
  • the device according to the invention enables a single-lane or multi-lane provision of web-shaped intermediate sheet material at a cutting area and comprises a removal device which is designed to remove the material web from a material supply, as well as a loop memory in which the material web has a loop with an inlet-side loop part and an outlet-side loop part forms, wherein the loop storage provides a receiving space for the loop, one side of which forms a support for one loop part and the side opposite the support forms a delimitation for the other loop part.
  • either the outlet-side or the inlet-side loop part can run over the support.
  • the receiving space can be both open and closed laterally.
  • the loop formation allows a decoupling of the highly dynamic ejection of the interleaf material into the cutting area from the Decrease of the material web from the relatively sluggish material supply. This ensures that the web length required in each case in the cutting area can be removed almost without delay and thus any tension and uncontrolled force transmissions in the material web during acceleration are avoided. Because the loop is guided at least partially on top of it, the loop formation can still be controlled in a particularly simple manner, and fluttering of the web of material in the machine room can be prevented by the two-sided delimitation of the loop in the loop storage device by supporting and delimiting.
  • the web guide in the loop storage device can be designed in such a way that the space requirement of the interleaver on or in the slicer can be minimized.
  • the receiving space has a mouth at least for the outlet of the outlet-side loop part and an end located lower than the mouth, wherein a plane running through the mouth and the end is inclined to the horizontal, in particular an angle in the range of 15 ° to 75 °, preferably from 30 ° to 60 ° and particularly preferably from 40 ° to 50 °.
  • Such an inclined arrangement of the receiving space enables a particularly space-saving integration of an interleaver in a slicer or a separate interleaver module assigned to the slicer.
  • the end of the receiving space is defined in particular by the fact that it determines the length of the receiving space that is effective for loop formation.
  • the course of the support and / or delimitation of the receiving space between the mouth and the end can be both flat and curved.
  • the loop part on the inlet side can also pass through the mouth as well enter the receiving space through an opening that is offset downwards or upwards in relation to the mouth.
  • both the support and the boundary each have an opening area at the mouth and an end area at the end, with both a plane running through the opening area and the end area of the support and a plane running through the opening area and the end area of the boundary
  • the plane is inclined with respect to the horizontal, in particular enclosing an angle in the range from 15 ° to 75 °, preferably from 30 ° to 60 ° and particularly preferably from 40 ° to 50 ° with the horizontal.
  • the support provides a flat support surface for the loop part and / or the delimitation provides a flat support surface for the loop part.
  • the support and the delimitation can run at least approximately parallel to one another in the longitudinal direction of the receiving space.
  • the distance between the support and the delimitation can define a clear width of the receiving space, with the ratio between the smallest clear width of the receiving space and the largest clear width of the receiving space, in particular if one is not taken into account Mouth of the receiving space, is greater than 0.8. It can be provided that the mouth is designed much narrower than the rest of the receiving space, i.e. has a significantly smaller clear width, which enables a particularly controlled introduction of the loop into the receiving space and reduces fluttering of the material web to a minimum, especially in the mouth area.
  • the distance between the support and the boundary can define a clear width of the receiving space at a respective position in the longitudinal direction of the receiving space, the ratio between the largest clear width of the receiving space and the length of the receiving space effective for loop formation being less than Is 0.5 or less than 0.3 or less than 0.1.
  • its clear width can be at least essentially constant in the longitudinal direction of the receiving space.
  • an at least substantially constant clear width of the receiving space or the largest clear width of the receiving space can be in the range from 10 mm to 60 mm and preferably in the range from 25 mm to 45 mm.
  • the receiving space can comprise lateral guides for the loop.
  • These tours can e.g. be designed as walls, but also as grids or other structures that allow the loop to be guided.
  • the receiving space is closed at least on one side, preferably on both sides. This increases the robustness of the recording space and allows the web guide to be designed in a particularly orderly manner. Furthermore, this configuration allows the use of negative pressure to form the loop or at least to support loop formation.
  • the receiving space can be designed with multiple lanes. This enables the interleaver according to the invention can be used in connection with multi-lane slicing of food products.
  • the receiving space preferably contains at least one separating element extending in the longitudinal direction of the receiving space in order to separate loops of material webs introduced in multiple lanes from one another.
  • the receiving space can consequently be subdivided into several sub-spaces, each of which represents a separate receiving space for the loop of the material web of the respective track.
  • the formation of loops in each lane is thus controlled and disruptions to an interleaver operated on multiple lanes due to a disordered path guidance in the loop memory can be avoided.
  • a particularly space-saving operation of a multi-lane interleaver is made possible, since the separating elements prevent the individual material webs from interacting with one another in the loop storage device and the material webs can thus be guided as closely as possible to one another.
  • the separating element can be adjustable in the transverse direction. This makes it possible to guide material webs of different widths through the loop storage and thus to meet the requirements of different products cut in the cutting area with regard to the size of the interleaver material made available.
  • the separating element is attached to the support of the receiving space.
  • the separating element can be positioned with the delimitation removed, which speeds up and simplifies both the setting to the required widths and the insertion of the loops in the receiving space, since the loops do not have to be laboriously threaded through a comparatively small opening in the receiving space.
  • the separating elements can also be attached to the boundary or a part of the separating elements can be attached to the support and the other part to the boundary.
  • the delimitation is formed by a removable cover.
  • the receiving space is particularly easily accessible and the components can be cleaned quickly and easily.
  • a loop can simply be inserted into the receiving space and does not need to be threaded through a comparatively small opening in the receiving space.
  • the delimitation can be displaceable relative to the support.
  • the length of the receiving space can be varied and, in particular, a maximum possible loop size can be selected and set.
  • the limitation can be closed.
  • the boundary can be transparent. Thanks to the transparent border, the formation of loops can be checked efficiently at any time and also during operation, so that any faults can be identified and eliminated particularly quickly.
  • the delimitation can be made of antistatic Plexiglas, for example, and other materials can also be provided.
  • the receiving space can have a suction area for the loop, which is connected to a vacuum source in order to act on an outside of the loop in the sense of a loop enlargement. Because of this active loop formation, this can be better compared to a passive, for example gravitational, loop formation controlled and the size of the loop selected and adjusted. This makes it possible to adapt the loop size as the non-inert material supply, which is used to provide the material web for highly dynamic ejection into the cutting area, to the respective requirements resulting, for example, from the product size and the cutting frequency. This can be of great relevance in particular in the case of multi-lane interleave operation, since the requirements with regard to the material to be ejected or its quantity can be different in different lanes.
  • one or more suction openings opening into the suction area can be provided, via which the vacuum source is or are connected to the suction area.
  • the receiving space can be multi-lane, with at least two lanes, preferably all lanes, having a suction area for the respective loop and being connected to a common vacuum source in order to act on an outside of the respective loop in the sense of a loop enlargement. It is therefore not necessary to attach suction devices for individual lanes in the case of interleavers operated in multiple lanes. Furthermore, it has been shown that no track-specific operation of a single suction device is necessary, but the desired track-specific control over the loop formation can be achieved with a single suction device that develops the same nominal suction effect on each track. As a result, the suction device can be designed in a particularly simple manner and the number of components and the space required for the suction device are minimized.
  • a braking device for the material web is integrated into the loop storage device. This ensures that the material web is tensioned in a controlled manner at all times.
  • the braking device preferably acts on the loop part on the outlet side.
  • the braking device can preferably comprise an outlet-side surface of the receiving space.
  • the surface on the outlet side can be part of the support or the delimitation of the receiving space, depending on the orientation of the receiving space.
  • the outlet-side surface can be made air-permeable and preferably provided with one or more suction openings.
  • the surface on the outlet side can be connected to a vacuum source.
  • a vacuum source This can, but does not have to, be in connection with a vacuum source as described above for sucking the loop into the receiving space or be identical to it.
  • a device for determining a measure for the size of the loop can be integrated into the loop memory.
  • the device can comprise at least one sensor which is effective in an outlet-side or inlet-side surface of the receiving space.
  • the senor can be a contact sensor or a negative pressure sensor.
  • a contact sensor reacts to contact with the material web and can, for example, be capacitive, inductive, electromechanical and / or electrostatic, while a vacuum sensor responds to the fact that the presence of the material web at the location of the sensor generates a vacuum.
  • the device preferably comprises a plurality of sensors arranged distributed in the longitudinal direction of the outlet-side surface. This makes it possible to obtain as precise and well-resolved information as possible about the current loop size and to adjust the loop size if necessary. For example, it can be provided to set the loop size to a certain desired size before the start of the feeding of the interleaver material into the cutting device or to change the loop size when it reaches a predetermined minimum or maximum during operation.
  • a control device can be provided which is designed to, before the start of the slicing of the products, by controlling the removal device, taking into account the actual loop size determined by the device, a predetermined, preferably determined from one or more parameters of a respective cutting program, Provide target loop size in the receiving room.
  • the target loop size can automatically be calculated from e.g. the cutting speed and the blade length can be calculated.
  • the control device can be designed to change the loop size on a lane-by-lane basis in multi-lane operation and to implement target loop sizes for individual lanes.
  • control device can be designed to initially cause the material web to be wound onto the roll of material when the machine is started by actuating the removal device and to stop this when the loop size reaches a predetermined minimum, which is detected by one or more sensors in the mouth area can.
  • the control device can then cause the removal device to remove the material web and convey it into the loop memory so that the loop reaches the application-related target size recognized by one or more sensors, whereupon the control device prefers the interleaver material into the cutting area by means of a conveyor device can be started.
  • This allows a controlled preparation of the interleaver for the highly dynamic material feed and guarantees a regular operating sequence from the beginning of the slicing process. Furthermore, it is ensured that the loop length is known to the system at all times and that the defined target loop length was actually reached before the start of the slicing process.

  • a plurality of sensors 41 are integrated into the support 23, which are designed here as negative pressure sensors and are connected to a negative pressure source 33, but can in principle also have a different effect. These sensors 41 register a negative pressure that arises when the outlet-side loop part 21 of the loop 19 lies on the area of the support 23 covered by the sensor 41.
  • a measure for the size of the loop 19 in the receiving space 18 is determined and sent to the control device 43, which coordinates the removal of the material web 13 as well as its advance and the cutting of the products.
  • the removal device, not shown, of the material web 13 can e.g. be caused to convey the material web 13 faster into the loop storage 17 when the loop 19 falls below a defined minimum size, or to stop the removal of the material web 13 when the loop 19 has reached a defined maximum size.
  • the size of the loop 19 can be brought to a certain desired size before the start of the feed of the material web 13 in the cutting area, not shown, which can be e.g. can result from the cutting speed and the blade length and is preferably calculated automatically by the control device 43.
  • suction openings 35 are formed in an outlet-side surface 39 of the support 23, via which the outlet-side surface 39 is in connection with a vacuum source 33.
  • the outlet-side loop part 21 can be sucked onto the outlet-side surface 39, so that a braking effect on the material web 13 arises.
  • the vacuum source 33 with the outlet-side surface 39 and the suction openings 35 thus form a braking device 37, which guarantees that the material web 13 is always under tension when it is fed into the cutting area and that forces generated during the feed are transferred to the material web 13 in a controlled manner.
  • the vacuum sources 33 for forming the suction region 31, for operating the vacuum sensors 41 and for providing them of the braking device 37 not to be arranged as separate negative pressure sources 33, as shown here, but rather to generate these effects by a single common negative pressure source 33. This enables simple and space-saving installation and can further reduce manufacturing costs by minimizing the components required.
  • Fig. 3 shows a view from above of a multi-lane loop storage unit 17 through the delimitation 25, which is advantageously transparent here.
  • the loop storage unit 17 is divided into four separate receiving spaces 18 by three web-like separating elements 30, the material webs 13 of a multi-lane and lane-individually operated interleaver each having one Form loop 19 in each of the four receiving spaces 18.
  • the material webs 13 enter the receiving spaces 18 through the mouth 27, the maximum loop length being defined by the end 29 of the loop storage device.
  • the dividers 30 are each transverse, i. E. displaceable in the direction of the double arrows, so that the loop storage device 17 can be adapted to material webs 13 of different widths and / or special track positions or track arrangements and can be quickly changed over to a new application. It is also possible in this way to equip different tracks with material webs 13 of different widths.
  • the width of the interleaver material provided can thus be adapted to the requirements of the product processed in the respective track, in particular to its slice size, and products of different sizes and shapes can be simultaneously supplied with suitable interleaver material.
  • the separating elements 30 also make it possible to easily convert the loop memory 17 to the required number of lanes, for example by simply pushing an outer separating element 30 outwards against the respective side wall 32 and so to speak in a "parking position". The remaining Separating elements 30 can then be positioned according to the respective application.
  • suction openings 35 In the lower area of the receiving spaces 18 there are suction openings 35, via which the receiving spaces are connected to a vacuum source (not shown), which in each case generates a suction area 31 in the receiving spaces 18.
  • a vacuum source not shown
  • the formation of the loops 19 in the receiving spaces 18 can be monitored and controlled, it being sufficient to form the respective suction areas 31 by means of a single negative pressure source which generates the same nominal suction effect in each suction area 31.
  • Fig. 2 shown loop memory 17 can be used here in connection with Fig. 3 described way be formed multi-lane.
  • Fig. 4 and 5 show further possible embodiments of a loop memory 17 of an interleaver according to the invention. These can be used depending on the requirements, in particular with regard to the space available.
  • the exemplary embodiments shown here are only intended to illustrate possible configurations and orientations of the loop storage devices, with other configurations also being conceivable and not intended to be excluded.
  • the loop storage device 17 is oriented in such a way that the incoming material web 13, which forms a loop 19 in the loop storage device 17, rests with the inlet-side loop part 20 on the support 23 and the outlet-side loop part 21 only rests against the boundary 25.
  • the solid line guidance of the material web 13 and the dashed line guidance of the material web 13 indicate two possible courses in and out of the loop storage device 17, particularly in view of the available space and the respective arrangement of interleaver and slicer relative to one another and the resulting path of the web of material 13 can be variable.
  • Fig. 5 shows an exemplary embodiment in which the material web 13 is guided through a slot 63 in the boundary 25 into the receiving space 18 in order to form a loop 19.
