Definitions

  • the present invention relates to a method for packaging small-sized products, in particular confectionery products, which are formed into stacked product groups.
  • small-sized products in particular confectionery products
  • confectionery products which are formed into stacked product groups.
  • it is a great challenge to assemble and package small-sized products into stacked product groups without fear of damaging the confectionery.
  • the completion of the package turns out to be extremely difficult.
  • the thus erected product group is gripped by a gripper together with the at least partially tubular wrapping packaging material.
  • the gripper therefore takes over the product group with the packaging material that has not yet been severed.
  • the completion of the packaging tube is carried out accordingly, while the product group is held by the gripper.
  • Most common grippers for example, are arranged on a packing head that rotates about an axis of rotation (see, for example WO 02/22445 A1 ).
  • a packing head is not suitable for transporting the not yet severed packaging tube.
  • the use of a gripper also opens up the possibility of approaching the most diverse areas of the scope of the product group and carrying out further packaging measures.
  • a first shortening of the length L can already take place when transferring the product groups to the conveyor and the products of a product group can be transferred from a product arrangement arranged in series into a fanned, at least partially overlapping product arrangement.
  • This diversified product arrangement facilitates the subsequent position alignment and prevents blocking or jamming of the products. Furthermore, this also ensures that unfavorable product shapes (for example cuboid shape, etc.) can also be used for a righting position alignment to be carried out.
  • a lens shape is less of a problem, but here too the diversified product arrangement is beneficial because it makes the process less susceptible to failure.
  • the conveyor may have receiving pockets for each product group, whereby the effective receiving length of the receiving pockets for erecting the products or the product group is shortened.
  • the receiving pocket may for example be provided with a front and / or rear sliding wall. But there are also elements that intervene in the area of the receiving bag and erect the products.
  • a rotatable separation plate which has group-shaped recesses for each product group, the products pass from above into the recesses and are delivered at a transfer station down from the recesses to the conveyor ,
  • the product supply can be carried out as bulk material.
  • Turning the separating actuator automatically leads to the filling of the recesses by the masses arranged on the turntable products.
  • the feed can be done by means of a vibratory feeder.
  • the recesses are arranged so that inevitably forms a product group with successively arranged products. As a rule, the products slide along a sliding surface, because the recesses are preferably open at the bottom.
  • this sliding surface can then be interrupted in the transfer area of the transfer station, so that the products fall out of the recesses and out into a receiving pocket of the conveyor.
  • the drop height can be very low here.
  • the movement of the turntable and the conveyor are coordinated.
  • the web-shaped packaging material is brought from above flat to the product groups conveyed by the conveyor and is subsequently transformed by forming means to a still open at the bottom packaging tube and the product group receiving portion of the conveyor from below into the engages open film tube.
  • the conveyor and the gripper have a common length over a certain length of travel, so that product groups can be transferred very easily, because a matched to the longitudinal extent of the product group conveyor line are performed jointly by both the conveyor and the gripper. This is not the case with rotating packing heads, where theoretically there is only one tangential point where the transfer takes place.
  • holding jaws of the gripper can preferably be placed laterally with the interposition of the packaging material on to each product group and the conveying of the product group by the conveyor can take over.
  • the grippers offer the possibility to carry out further process steps on the packaging material at the bottom of the product group.
  • the product group usually lies with its underside, which is why access there is difficult.
  • the grippers already position the packaging material over a large area of the circumference of the product group, but allow said access.
  • the grippers further convey the product groups together with the packaging material substantially in the same conveying direction as before the conveyor. Due to the fact that the grippers essentially take over the conveying of the product groups from the conveyor and essentially maintain the conveying direction, the packaging material does not necessarily have to be separated into individual product sections before the transfer, but can still be handled as a strip material. This offers the possibility of finishing the packaging material hose, while several product groups have already been taken over by the gripper. This is not possible with the otherwise usual rotating packing heads.
  • a longitudinal fin is formed and sealed during the production of the packaging and the formation of the packaging tube.
  • the use of a sealed longitudinal fin also paves the way for the packaging to be used as primary packaging.
  • cold seal adhesives are used, the adhesive areas are applied to the same side of the packaging material and then pressed together in the continuous process. This can also be used to pack heat-sensitive products.
  • heat sealing foils can also be used.
  • Such a longitudinal fin can be produced while the product groups have already been taken over by the grippers.
  • the longitudinal fin can be applied to the product group for a more pleasing appearance.
  • a certain prestress in the packaging material hose between two product groups, each held by a gripper can already be generated by holding the gripper.
  • the latter is at least additionally prestressed between two product groups. Accordingly, there is a targeted introduction of a bias favoring the severing. If there is already a certain preload by the mere access and transport of the gripper, this preload is deliberately increased again. Here, for example, provide additional units on the gripper, which generate this bias.
  • the grippers in front of and behind the holding jaws can have refining units which, for closing the open ends of the packaging material tube, gather them and form a clamp closure and funnel-shaped closure ends.
  • This is a very quick and easy way to create a visually appealing shutter.
  • the packaging material can be made up in such a way that even in the region of the "gathering knot" a sealing takes place, for example with a cold-seal adhesive or heated pair of cups.
  • a shapely primary packaging is then produced. There is thus no further Umverpackung more necessary and the packaged product group can be brought into the sales channel.
  • the gripper can deliver it to a conveyor which, at least initially, further conveys the packaged product group in the conveying direction or at most with an offset of half the height of the packaged product group.
  • the packaged product group is therefore released gently from the gripper for further promotion. Unnecessary fall heights are thus avoided.
  • the invention relates to an apparatus for packaging small-sized products, in particular confectionery products, with a web-shaped packaging material.
  • the device comprises a plurality of grippers, each of which has holding jaws for holding the product or product group at least partially enveloped by the web-shaped packaging material, and grinder units arranged in front of and behind the holding jaws for producing a clamp closure and funnel-shaped ends of the packaging.
  • the gripper device provides the grippers with a gripper track which runs parallel to the conveying direction predetermined by a conveyor supplying the product or the product group of the gripper device, at least over a predetermined length section which is greater than the length of a product or a product group.
  • Conventional gripper devices are designed as packing heads and rotate about an axis.
  • the gripper device is capable of at least a part of the predetermined path of the conveyor to follow (eg at least 2 times the product length or 1.5 times the length of the product group or until the entire package is completed).
  • This opens up the possibility of handing over the packaging material in web form without first dividing it into corresponding product sections.
  • the subsequent dicing operation can then be performed, for example, on the gripper device, which usually gives better access than the conveyor.
  • the gripper device can be brought in with the grippers from above, while a support from below through the conveyor continues to take place until the grippers take over. Accordingly, the grippers move back up after delivery of the product or product group.
  • the gripper path between the acquisition of products or product groups and the levy is straight.
  • the holding jaws can be controlled in such a way that they grip the product or product group at least partially enveloped by the web-shaped packaging material, before the web-shaped packaging material in the respective product or the respective product group is associated with severed portions.
  • the packaging of lenticular products P which are formed into a product group G, explained in more detail below.
  • the device and the associated method described below are also suitable for other product forms (for example spherical or cuboid).
  • certain process steps or parts or areas of the entire device are also suitable for packaging and handling of individual products.
  • the gripper device described in more detail below accordingly also serves for the handling and processing of individual products and the associated packaging material.
  • the illustrated device 1 comprises a separating device 2, a transfer station 3, a conveyor 4, a Heidelbergsungsffenzu GmbHstation 5, a gripper device 6 and a conveyor 7. From the transfer station 3 to the conveyor 7 substantially a linear constant conveying direction F is maintained.
  • the device 1 is used to produce a packaged product group VP (see FIG. 2 ).
  • the products P are lenticular confectionery (for example drops) which are to be formed into a product group G consisting of five products P and packaged together.
  • the number and shape of the products P can be arbitrary as long as they can be grouped in this way.
  • the tubular package V is formed from a web-shaped packaging material VM.
  • the packaging V should serve as a primary packaging and must therefore be hermetically sealed.
  • the special feature of the packaging V are also the two funnel-shaped or trumpet-shaped closure ends VE in the form of shirred "knots" and an applied longitudinal fin LF in the form of a fin seam.
  • the packaging material VM therefore encloses the product group G on all sides.
  • the packaging material VM is made up in such a way that the film layers stick together both in the area of the fin seam and in the region of the knots. It is therefore a closed, not self-opening packaging V, in which the product group G is kept in the predetermined product formation.
  • the separating device 2 comprises a continuously rotating separating plate 8.
  • the separating plate 8 has in the region of its outer circumference circular recesses 9, which are arranged along a pitch circle and thus circulate annularly (see FIG. 3 ).
  • the recesses 9 are combined into recess groups 10. Each five recesses 9 form a recess group 10.
  • the recesses 9 are arranged so close to each other that they touch or slightly overlap. This makes it possible for the products P arranged in the recesses 9 to touch or almost touch within a recess group 10.
  • the product feed takes place as bulk material.
  • the products P are then received individually in the recesses 9 and thus form successively arranged product groups G.
  • the recesses 9 are dimensioned such that only a single product P is added.
  • deflectors are used, inter alia, in the form of brushes and guide devices (not shown).
  • the recesses 9 in the separating plate 8 are already arranged in groups. This means that the length of the product group G on the separating plate 8 is greater than the length of the product group G arranged inside the packaging.
  • the separating plate 8 rotates counterclockwise and conveys the separated and grouped products P to the transfer station 3 In this case, the products P accommodated in the recesses 9 of the singling positioner 8 slide horizontally during the rotation of the singling positioner 8 over the sliding surface of a slideway (see FIG FIGS. 4 to 6 ).
  • the conveyor 4 is arranged below the separating actuator 8.
  • the conveyor 4 extends with its conveying direction F substantially tangential to the pitch circle of the recesses 9.
  • the conveyor 4 has a feed chain 12, of which only some of the drivers 13 are shown.
  • the feed chain 12 is usually a roller chain, on which the drivers 13 shown are arranged at a predetermined distance (driver pitch).
  • the drivers 13 are made relatively narrow and engage from below in a rail 14 with side walls. Between two drivers 13 and the rail 14 thus a moving receiving pocket 15 is formed.
  • the slide 11 is interrupted. Due to gravity, the products P reach the receiving pocket 15 running synchronously with the product group G.
  • the size (length) of this receiving pocket 15 is designed such that the respective number of products P, which are combined in a pack V, are respectively received.
  • the products P in the singulator 2 it is advantageous if the products P lying, i. with a strong focus.
  • the products P thus assume their most stable position.
  • the most stable position does not correspond to the product formation which the products P take later in the packaging V.
  • the transport of the transferred to the chain tray 15 products P takes place with a support plane contained in the receiving pocket 15 TE.
  • the continuous speeds of the separating actuator 8 and of the feed chain 12 are matched to one another in such a way that the segmented recesses 9 of the singling actuator 8 always coincide with a driver pitch or receiving pocket 9.
  • the position assignment between separating plate 8 and feed chain 12 remains secured accordingly.
  • the alignment of the products P on the lateral surface is required.
  • the lying flat product groups G must be erected. That is, the center of gravity of the products P is raised and the products P are then in a more unstable position.
  • the bearing alignment takes place within the continuously running supply chain 12.
  • the geometry of the products P requires a backup of the erected product group G, so that it does not tip over.
  • the side surfaces of the product P do not allow it to stand erect without support.
  • the rail 14 thus also represents a lateral boundary.
  • the actual erection process is carried out by a erecting lever 16 pivotally arranged on the driver 13.
  • the movement of the erecting lever 16 is effected via a frame-fixed cam control and a control cam 17 arranged at the other end of the erecting lever 16.
  • the erecting lever 16 pivots counterclockwise in the chain compartment 15 and sets up the product group G.
  • the lying product group G in the receiving pocket 15 has a length L1 and the erected product group G, the upright 16 against the rear End of the receiving pocket 15 is pressed, has the length L2.
  • the length L2 is smaller than the length L1.
  • the initial product group G is thereby converted into a stationary product group G (see FIG. 7 ).
  • the product group G is moved from the conveyor 4 to the package feeding station 5.
  • the packaging material VM is fed in web form.
  • forming devices forming shoulder, etc.
  • the upright product group G is then inserted by means of the conveyor 4 into this still open packaging tube PS.
  • the supply chain 12 enters through the hose opening of the packaging material hose PS, so that the product group G is enveloped by the packaging material VM to a large extent.
  • the erected product group G is further transported by the feed chain 12 until it reaches the area of the gripper device 6.
  • the gripper device 6 has band-shaped circumferential chains on which grippers 18 are arranged at certain pitches.

  • These drivers 13 are repeatedly arranged on the drive chain, such as a roller chain, the feed chain 12 in the predetermined pitch.
  • the dimensioning of the cam control and the linkage is designed such that the initiated on the products P movement leads to the ereder derselbigen and no Damage to the product P causes.
  • the outer surfaces of the products P slide together during the erecting process.
  • the shape of the product cross-section supports the avoidance of jamming products P during the erection process.
  • the preorientation of the product layer within the receiving pocket 15 must, with a different product cross-section, prevent blocking of the products P during the erection process.
  • supporting elements in the region of the feed chain 12 and the frame-fixed outer product guides are e.g. Rail) applicable, which support the orientation of the product layer during the erection movement.
  • a roller chain serves as an endless, revolving drive element.
  • the drivers 13 are added to frame-mounted guideways and follow the chain movement directly.
  • the force is introduced into the guides of the driver 13, not in the chain strand.
  • the chain strand is operated continuously circulating.
  • the objective is to maximize the efficiency of the processing operation, so that missing individual products P in the area of the product transfer from the singling plate 8 into the feed chain 12 are to be avoided under given process reliability.
  • incompletely filled recesses 9 of a recess group 10 in the singling plate 8 can be sensed.
  • the transfer station 3 is shut off by means of a separately switched lock washer exclusively for this product group, so that a transfer of the products P from this incomplete filled segment (recess group 10) does not take place in the feed chain 12.
  • the incompletely filled segment of the singling positioner 8 is fed to the singling process in its current composition during a further rotation of the singling positioner 8.
  • the receiving area 15 of the synchronously running feed chain 12 located in the transfer area no products P are handed over.
  • the feed chain 12 continues to run continuously.
  • the empty receiving pocket 15 passes through the entire section of the feed chain 12 up to and including the area of product transfer into the rapier band 19.
  • the closing holding jaws 21 of the gripper 18 can not make contact with products P.
  • the design of the holding jaw arrangement is selected such that its closing movement is realized spring-loaded. Under the action of a roller lever of the gripper 18, the outer, cam-mounted curved tracks exclusively perform the movement for opening the holding jaws 21. This design ensures that the holding jaws 21 reduce their distance to each other in the absence of product formation to a minimum, so that the packaging hose PS is clamped directly by the holding jaws 21.
  • the processing of the packaging material hose PS takes place here on the further feed path of the rapier band 19 analogously to the process described without deactivating individual processing steps.
  • the discharge of an empty pack is carried out, which is handled separately from the product flow of the packaged products VP.
  • a further embodiment for avoiding the resulting empty bag is the decentralization of the drives of the separating actuator 8 relative to the feed chain 12.
  • the blocking of the incompletely filled segment of the separating actuator 8 by a locking disc is driven continuously.
  • the separator 8 is impressed by the control of the drive, an additional positional offset, so that in the product transfer to Zucommendedkette 12 the next, completely filled product group G of the singling 8 is synchronized to the position of the receiving pocket 15 of the feed chain 12.
  • the generation of a package V by means of the rapier band 19 can also be done with individual products P instead of product groups G.
  • the product group G does not necessarily have to be aligned with the lateral surface.
  • the products P can be supplied to the rapier band 19 also lying.
  • the product supply can be carried out by means other than a separating plate 8, for example by means of strip feed, direct input into the continuously running feed chain 12, etc.
  • the formation of the product groups G does not have to be effected by segmentation of the separating plate 8 into individual groups.
  • the feed chain 12 does not necessarily have to be formed as a continuous chain strand. It is also the execution by means of separate driven Driver 13 possible (single linear drives).
  • the transfer of the products P in the feed chain 12 is also possible with auxiliary devices for safe ejection from the recess 9 of the separating actuator 8.
  • the erecting of the products P is also by the relative movement of two drivers 13 conceivable, which are arranged on individual controlled linear actuators.
  • the erecting of the products P can also be controlled by the sliding wall of the receiving pocket 15 or an erecting lever 16 arranged in this region.
  • the vorrauseilende wall of the receiving pocket 15 is fixed in this embodiment.
  • the raising can also be done by the relative movement of two elements of the driver 13 and center the product group G, for example, in the region of the driver center.
  • the product contour does not necessarily have to be elliptical for erecting.
  • the drivers 13 can also be driven by other endless, rotating drive elements.
  • the drive of the driver 13 is also possible via individual drives.
  • the drive of the rapier band 19 can also be realized as a single drive for each gripper 18 (linear drives). Instead of cold sealing, heat sealing or other sealing technologies are conceivable. Several or all sealing roller pairs can be driven.
  • the pivot points of the two Raffer a Raffercrues 22 can also be arranged offset to one another in another embodiment.
  • a concentric axis of rotation is not mandatory.
  • the embodiment of the shirring is significantly influenced.
  • the separating cut can also take place off-center between two grippers 18.
