Abstract

The packing unit for disc-shaped plastic carriers to produce packs for tins and cans combines the carriers to column-shaped bundles. This facilitates transport on pallets and the charging of carrier magainzes of a machine tp complete such packs. This is effected by alignment of the carriers on a strap against a support pate which rests on this strap and lies with its support face within the contours of the carriers. At its top end this strap remains clear of the carriers. This ensures a satisfactory feed of carriers to a production machine for the container packages.

Description

The invention relates to a packaging unit for schei-

ben-shaped plastic carrier, which is used for the production of cans or Like. -Multi-piece packs are intended, each with at least one of the disc surface Recess extending through to disk surface. The invention also relates to such Packaging units loaded pallets and a device for loading the vertically arranged carrier magazine of a machine for the production of cans or Like. -Multi-piece packs with the packaging units.

Disc-shaped plastic carrier of the type mentioned and through they are numerous advantages for trade and for the consumer, e.g. previously known from DE-GM 76 26 346; however, the benefits of canned or the like.

-Multiple packs with disc-shaped plastic carriers only then come into play if it is possible to produce the multiple packs inexpensively. But this requires that the disc-shaped plastic carrier with the cans or the like. Containers to multipack in a high number of pieces per unit of time by means of be combined in a suitable machine.

The invention is intended as a further prerequisite for the cost-effective Production of multi-piece packs with little effort and with low susceptibility to failure a sufficient supply of a machine for the production of cans or the like. -Multi-piece packs be ensured with disc-shaped plastic carriers. This task will solved according to the invention by the transport on pallets and for loading the Carrier magazine of a machine for the production of cans or the like. -Multi-piece packs intended combination of the carriers into columnar bundles by means of congruent Line up of the carriers on a rod against one arranged on this, end-side and with its support surface lying within the outline of the carrier, the rod remaining free of carriers at its upper feed end.

The summary of the disc-shaped plastic carrier to form columnar Bundling according to the invention is advantageous in several respects. Can once the carriers are quickly lined up and removed from the rod, and the empty stick can also be reused. Second, the disc-shaped Support in their columnar arrangement by the rod against falling apart secured. In addition, the columnar bundles can be gripped by the upper, remaining free feeding end of the rod can be easily handled.

If necessary, a mechanical relocating or transferring device can also be used here. Robotic facility attack.

A further development of the invention is based on disc-shaped plastic carriers, in each of which on at least one disk surface with perpendicular to this parallel axes each in two rows next to each other without mutual offset circular sockets for receiving cans or similar containers are arranged, whereby at least once between four adjoining versions one formed by the gussets between the also circular outer walls of the mounts, there is a continuous recess gee from disk surface to disk surface.

For this purpose, the further invention provides in an advantageous manner that the rod with the narrow sides of its elongated rectangular profile in each case two opposing gussets of each at least once between four on each other bordering versions existing, continuous recess of congruent carrier is included, and that the support plate designed as a rectangle of the rod is arranged transversely at its lower end and the lowermost beam of the Support bundle in the area of the other two gussets, which are transverse to the gussets receiving the rod are directed.

This achieves with little effort that the rod at both inexpensive commercial rectangular cross-section, the carrier against rotation secures as well as holds the girders together as a columnar bundle. By the arrangement the support plate transversely to the rectangular cross-section of the rod can be the plate in the simplest Be welded to the lower end of the rod without the risk of that the lowest support of the support column with parts of its sockets on the welds sit up and be damaged as a result.

The packaging unit designed according to the invention is excellent suitable for transport on pallets. There is a particularly advantageous training feature of the invention in that the pallet is loaded with the packaging units in the manner is that the columnar beam bundles arranged vertically in a plurality closely to closely with the support plate arranged at the lower end of the rods in recesses added to the top of the pallet and at its upper end by a joint Frames are held together and additionally strapped by steel tape or Like. Can be provided.

The frame can for example be formed by angle profiles.

The strapping can be used with a view to particularly strong impact loads the pallet during transport.

Furthermore, according to the invention, the commercially available pallet a perforated plate provided with the recesses can be applied, which the lower Support plates of the placed on receives columnar carrier bundle.

This means that it is not necessary to use special pallets. Much more the commercially available pallets can be used in a cost-effective manner. For the loading with the columnar carrier bundles is merely the application of a Perforated plate required on the pallet. The pallets can therefore always be under Omission of the perforated plate can also be used for other goods.

The invention also includes a device for loading a vertical arranged carrier magazine of a machine for the production of cans or the like. -Multi-piece packs with the packaging units designed according to the invention. The loading device is characterized according to the further invention by at least one horizontal running, with recesses for falling out of the rod from the columnar Carrier bundle downward provided intermediate storage area, by means of which a through Falling out of the rod from the vertical arrangement on the intermediate storage area attached carrier bundle, carrier bundle that has become rodless, sideways into the carrier magazine is movable.

On the at least one intermediate storage area provided according to the invention is constantly something that has become rodless due to the staff falling out of its own accord columnar carrier bundle temporarily stored. As soon as the carrier filling of the machine magazine has dropped below a certain level, the temporarily stored Rodless carrier bundles sideways into the machine magazine by means of the intermediate storage area moved and placed on the remaining filling in the machine magazine. That can for example, by a straight back and forth movement of the intermediate storage area happen, being expedient, namely before the intermediate storage area the end the machine magazine is moved back, a counter holding surface to rest on the carrier bundle is brought, which strips the bundle from the intermediate storage area and the Carrier during the removal of the individual carrier from the machine magazine in this locked at the side.

For machines with higher powers, the invention provides a special one advantageous further training. According to the invention, this consists in that several Intermediate storage areas with lateral support guide at the same distance on one each horizontally movable in sections by a pitch, with his a reversing forming drive wheel arranged next to the carrier magazine of the machine Pulling means are arranged such that the intermediate storage area next to the carrier magazine from a position next to the one, predominantly wall-free side of the magazine a straight part of the path and an adjoining part from the tangential direction, a part of the path describing a quarter of a circle in a position next to a right-angled parallel to the side wall of the carrier magazine which runs parallel to the predominantly wall-free side is shifted, one directed in the direction of the rectilinear part of the path the side remote from the direction of movement on the intermediate storage area, the vertical wall having the height of a beam bundle the rodless beam bundle pushes into the carrier magazine and in the period between two section-wise movements of the endless traction means protrudes with its end section into the carrier magazine and there the previously introduced rodless carrier bundle in the carrier magazine at its predominantly wall-free side locked.

Due to the further development according to the invention, it is basically possible the carrier magazine of a machine for manufacturing of canned or The like. -Multi-piece packs with groups of disc-shaped groups arranged in a column To load plastic carriers largely automatically. Through the intermediate storage areas the storage capacity of the machine's magazine is increased many times over. This can save operating personnel. The one operator who Monitoring functions on one or at the same time on two or more manufacturing machines exercises, can meanwhile on the intermediate storage areas of one or the two or more loading devices set up carrier bundles without disrupting the barrel the machine must be interrupted. Occupying the intermediate storage areas can due to the bundle training provided according to the invention in connection with the conveyance and provision of the bundles on pallets and also in connection with the automatic falling out of the rods from the carrier bundle with little expenditure of time be handled.

Further features and advantages of the invention are several exemplary embodiments refer to, which are shown schematically in the drawing and below are described in more detail.

1 and 2 show two partial side views of the of the invention for the columnar bundling of the disc-shaped plastic carrier provided rod with end support plate, the carrier being dash-dotted are indicated.

Fig. 1 to 4 show the transport on pallets and for loading of the carrier magazine of a machine for the production of cans or similar multi-piece packs suitable combination of disc-shaped plastic carriers 1 for cans or Like containers to form columnar bundles 2.

The disk-shaped plastic carrier shown in Figure 3 and 4 1 have circular sockets 5 on both disk surfaces 3 and 4 for receiving Cans or the like. Containers. The axes of the mounts are perpendicular to the disk surfaces and directed parallel to each other. The sockets are without on each lens surface mutual displacement arranged in two rows of three side by side, with they form coaxial pairs from disk surface to disk surface.

Between four adjoining versions 5a to d or 5c to f is a recess extending from the disk surface 3 to the disk surface 4 6 or 7 available. The two recesses 6 and 7 are through the Zwikkel 6a to d and 7a to d between the likewise circular outer walls of the sockets 5a to f formed.

The rod 8 has an elongated rectangular profile 9.

The ends 9a and b of this profile are in the two opposite one another Gusset 6b and d of the through recess 6 of the disc-shaped plastic carrier 1 recorded. This results in an essentially twist-proof alignment of the Carrier 1 on the rod 8 allows.

The support plate 10 arranged at the lower end of the rod 8 is also designed as an elongated rectangle 11. It supports the lowest disc-shaped Plastic carrier 1a of the columnar carrier bundle 2 in the area of the other two Gusset 6a and c of the through recess 6, which transversely to which rod 8 receiving Gussets 6b and d are directed.

Because of this design of the rod 8 with an end support plate 10 can the latter in a cost-effective manner by welding 12 at the end of the rod be attached.

There is no risk that the from a large number of disk-shaped Plastic supports 1 existing column on the lowest support 1 a with parts of whose frame edges sit on the possibly sharp-edged weld seams and the frame edges concerned suffer damage. Such damage but must be safely avoided, as a in the carrier magazine of the manufacturing machine The production process is interrupted by the plastic carrier that has reached the sockets and has been damaged the machine would interfere.

The feed end 8a of the rod 8, over which the disc-shaped plastic carrier 1 against the end support plate 10 on the rod in each case disc surface 4 on the disc surface 3 are lined up in a large number, expediently remains free of plastic carriers. At this upwardly protruding end 8a of the rod 8, the columnar Carrier bundle 2 easily picked up by machine or by hand, moved sideways and put down again will.

Of course, a robot device can also be attached to the free end of the rod attack.

In Figure 3 is in the area of the existing second gusset space 7 also a rod 8 'with end support plate 10' is shown. The selected one with a dash-dotted line Representation only signals an alternative arrangement of the rod 8: The Disc-shaped plastic carrier 1 are therefore each used to form a columnar Carrier bundle 2 all either with the one continuous from disk surface to disk surface Gusset recess 6 or lined up with the gusset recess 7 on a rod 8. The disk-shaped plastic carrier 1 belonging to a bundle must be the Rod 8 in the case of the gusset recess 6 either with the gusset pair 6b and d or with the pair of gussets 6a and c and in the case of the gusset recess 7 either with the Pick up the pair of gussets 7b and d or uniformly with the pair of gussets 7a and c. in the With regard to a uniform treatment of the columnar carrier bundle 2 in It can also be advantageous for transport and when feeding into the carrier magazine of a machine be to arrange the rods 8 in a matching manner from beam bundle to beam bundle.

FIGS. 5 and 6 show one loaded with columnar carrier bundles 2 Pallet 13. On the commercially available pallet (in the present case a Four-way pallet) a perforated plate 14 is placed. The carrier bundles 2 are in a vertical position Arrangement in a multitude of closely spaced apart with the support plate 10 in recesses 15 the perforated plate 14 added, at its upper end are the columnar support bundles 2 held together by a common angle profile frame 16. The recesses 15 and the angled profile frame 16 are able to stand alone, without additional measures necessary are the load formed from the columnar beam bundles 2 on the pallet to hold together, especially since the bundles are close to each other and thus their stability increase each other. In addition, however, strapping can be provided, which hold the load and the pallet vertically. Then the pallet load is also against Particularly robust handling secured during transport. In Fig.5 there are two straps 17 indicated by dashed lines, which can be formed, for example, by steel band.

Needless to say, the arrangement of the columnar support bundles 2 and the respective arrangement of the rod 8 in the bundles 2 on the one hand and the Corresponding arrangement of the recesses 15 in the perforated plate 14 on the other hand. The carrier bundles 2 are expediently arranged so that they are longitudinally extended their substantially rectangular outline in plan view are aligned. It is also useful to determine the position of the rod 8 within the respective bundle always to be chosen uniformly. In the charge shown, these two are expediencies observed.

Can be seen a range based on the summary of the disc-shaped plastic carrier to form columnar bundles by means of lacing loading and unloading a rod considerably quickly against an end support surface will. By having the end support plate each from a recess in the pallet or is received in the perforated plate, the support column rests on the relatively large-area underside of the lowest beam on the pallet or the perforated plate on. This means that when the pallet is at rest and is sufficiently horizontal there is sufficient stability for the individual bundle on the pallet. This means that the pallet can be loaded and unloaded without the need for an additional one Rebate the bundle needs at its upper end.

The placement of the angle profile frame is therefore used to secure of the load while the pallet is being transported.

Used to unload the pallet after the pallet has been transported, the angle profile frame removed from the load, the bundle load remains inherently stable on the pallet stand. The carrier bundles can be gradually removed from the pallet, without the risk of the residual charge falling apart.

7 to 10 relate to the automatic loading of the vertically arranged Carrier magazine of a machine for the production of cans or similar multi-piece packs, which, in a manner not shown, each consist of a disk-shaped plastic carrier and from cans pressed into the circular sockets on the pane surfaces and the like. Containers exist.

Several intermediate storage areas 18 with lateral support guide 19 are at the same distance A on one in each case by the pitch A in sections horizontally movable endless traction means 20 arranged, which in the present Trap is designed as a double link chain. With his, a reversal 21 forming Drive wheel 22 (chain star) is the endless traction means next to carrier magazine 23 the machine not shown for the production of cans or the like. -Multi-piece packs arranged. During the section-wise movement of the endless traction means 20 in each case by a dimension equal to the distance A of the intermediate storage area 18 from one another The intermediate storage area 18 which is closest to the carrier magazine 23 in each case becomes the path length each from a position 18a next to the one predominantly wall-free side 24 of the Magazine 23 over a straight path part B and one on it from the tangential direction subsequent, a quarter circle arc describing further part of the route C into a Position 18b next to one at right angles to the predominantly wall-free Side 24 extending side wall 25 of the carrier magazine 23 is displaced in parallel. Included pushes one in the direction of the straight path part B, on that of the Direction of movement of the rectilinear path part B remote side on the intermediate storage area 18 arranged, the height of a columnar carrier bundle 2 having vertical Wall 26 the carrier bundle 2, which has previously become rodless, into the carrier magazine 23. In the period between two section-wise movements of the endless traction means 20 The sliding wall 26 protrudes with its end section 26a into the carrier magazine 23 and there locks the carrier column previously introduced into the carrier magazine 23 on the mostly wall-free side 24.

The intermediate storage areas 18 are provided with the recesses 27, through which, after a carrier bundle 2 has been placed, the rod freely falls out downwards can. The respective carrier bundle 2 is both against the sliding wall 26 and placed against the additional support wall 28 on the intermediate storage surface 18. As shown in FIG. 10, despite the pivoting of the support column that has already occurred 2 can still be seen, the two formed by gussets, from the disc surface to Disc surface through recesses 6 and 7 perpendicular to the recesses 27 and within their outlines, so that, as under-referring to Fig.3 clearly it can be seen, the rod lining up the carrier with its end support plate after can fall out below as soon as the carrier bundle in question at the upper free end 8a of the bar 8 placed on an empty intermediate storage area 18 from the pallet has been.

During the movement of the intermediate storage areas 18 over the path portions B and C from position 18a to position 18b is done with reference to FIG Fig. 10 in more detail the following: The separating edge 29 of the wall 25 of the Magazine 23 penetrates between the support wall 28 of the intermediate storage area 18 and the a support column 2 lying thereon and guides the support column into the magazine space 30 between the wall 25 and the opposite wall 31, which is useful with a protruding inlet part 32 is provided. The support column learns some horizontal panning. While moving on the quarter circle arc C, the carrier bundle 2 is pushed completely into the magazine 23 by means of the wall 26 (Compare the dash-dotted representation 1 ', 2' in Fig.10). The intermediate storage area moves in the process 18 through the horizontal slot 33 in the magazine wall 25 from the interior 30 of the magazine 23 outwards into the position 18b. The one shown in phantom At the end of the sliding wall, the inserted carrier bundle 2 'is locked in the magazine 23

The drive wheel 22 of the endless traction means 20 is driven by the motor 34 driven via the gear 35 with a built-in brake. The drive shaft 36 has the switching pin 37 downwards. On this one are shifted around 1800 capacitive switching elements 38a and b arranged through which the capacitive disconnection device 39 is switchable.

The switching position corresponds to the position 18b of the intermediate storage area 18 one of the two elements 38a and b opposite the capacitive disconnection device 39. The switching pulse triggered in each case causes the drive motor 34 to be de-energized and the brake assigned to it becomes effective. Once the minimum fill 40 of the magazine 23 is reached with disk-shaped supports 1, the flexible feeler jumps 41a of the switch-on device 41 further into the interior 30 of the magazine 23, whereby a switch-on pulse for the drive motor 34 is triggered. As in Fig.

9 indicated by friction linings 42 is the drive wheel 22 of endless traction means 20 connected to the drive shaft 36 via a friction clutch 43. Another safety device is in the form of a timing relay, not shown provided, which causes the shutdown of the drive motor 34 when this not switched off by the device 39 within a certain minimum period has been.

It can be seen from FIGS. 8 and 9 that the intermediate storage areas 18 each pivotable about an axis 44 running parallel to the traction means 20 on the endless traction means 20 are arranged and according to during the rectilinear movement the position 18a are slightly inclined, so that the columnar support bundle 2 are tilted slightly against the wall 28. This will change the position of those who have become rodless columnar carrier bundle additionally secured on the intermediate storage areas 18.

The falling out of the rod 8 from the carrier 2 through a recess 27 of an intermediate storage area 18 can - if desired - by what is not shown Open beforehand, e.g.

through a sliding strip, downward to blocked recesses 27 take place at a predetermined point on the conveying path.

The refilling of the magazine 23 takes place precisely and in good time without any action on the part of the operator, who is thereby freed for the unproblematic loading of the intermediate storage areas 18 and other work.
