Device for sticking protective bags on

Album sheets

The invention relates to a device for gluing protective bags onto album sheets.

Such a device is not previously known, although albums with glued protective pockets on the for years Market and there is a great need for them. So far, the individual protective bags on one side have to be Have a water-soluble adhesive layer, moistened and applied by hand to the individual album sheets, what is very tedious, time-consuming and expensive, because the bags are individually selected, aligned and angularly, in part must be glued symmetrically in preprinted fields,

straightening station 4, where it is transferred electronically or mechanically
a print mark control can be aligned by means of a known alignment device. The aligned album sheet is picked up in cycles by a snap gripper 5. Depending on its position and the necessity in the further operation, the album sheet is turned over beforehand by a sheet turner 6
or not. The snap grippers 5 clamp the centered album sheets 2 at an edge perpendicular to the conveying direction and hold them during passage through the device, so that it is ensured that each centered supplied album sheet 2 is always arranged in the same position in each processing station.

Several drag grippers 5 are at equal distances from one another, which correspond to the distances between the processing stations, with their ends on two in the same mode leaving a distance between them parallel to one another
Deflection rollers 7 guided endless conveying means 8, such as chains, belts or the like arranged.

The distance between the two conveying means 8 is chosen so that the edges of the album sheets perpendicular to the gripping edge 2 can rest on the funding 8. To also provide other formats of album pages 2 with protective pockets 1 to be able to, the distance between the two conveying means 8 can be adjusted, e.g. by means of a spindle drive or Spacers, then the bracket of the snap gripper

9038 ^ / 0445

is designed on the conveyor 8 so that it allows changes in distance. This can be done, for example, in such a way that
the actual snap elements are only arranged on a section which corresponds to a predetermined minimum distance and has extensions on both sides which can be displaced and locked in holders of the conveying means 8
are. In order to avoid sagging on the fourth side of album sheets 2, which have a low inherent rigidity, between the two conveyor parts
Supports (not shown) for the snap gripper 5
opposite edge of the respective album sheets 2 can be used interchangeably.

In another exemplary embodiment, not shown, the distance between the two conveyor parts cannot be changed
and corresponds to the maximum size of the area of an album sheet 2 which is to be provided with protective pockets 1.
In order to also be able to process narrower album sheets 2, holders for mandrels are provided in both conveyor parts 8, with which the distance between the conveyor parts can be reduced so that the sides of a narrower one
Album sheet 2 no longer rest on the actual funding parts, but on the thorns. If the conveying means are 8 chains, these mandrels can be inserted into the joint bushings.

$ 09845/0448

Each album sheet 2 is first fed to a moistening station 9 by the cyclically moving conveyor 8. As soon as the album sheet 2 has reached a certain position in the moistening station 9, the conveying means 8 stops and is triggered by means of a switch, e.g. a magnetic switch or a light barrier, a piston cylinder moves in the direction of the non-printed side of the album sheet 2 10 actuated counter pressure plate 11 and in the direction of the printed side on a base plate 12 arranged with extendable piston cylinders 13 provided moistening devices 14. The movements are coupled so that when the counter pressure plate 10 reaches the back of the album sheet 2, the moistening devices 14 rest with their work surfaces on the front and fields according to their size moisten the album sheet 2. The size of the actual moistening area is in order to also have clean adhesive connections on the sides to achieve, slightly less than the intended adhesive surface on the protective pouches 1. The length of stay and thus a sufficient one Humidification depends on the nature of the material of the album sheet 2, e.g. on its absorbency, the water-soluble adhesive used for sticking on the protective bags, the porosity of the actual humidifier, as well as the dampening agent used and is determined empirically. Then move moistening devices 14 and Counter pressure plate 11 by the reversed cylinders 10, 13 apart and the conveyor 8 starts moving and conveys the moistened album sheet 2 by one cycle to the adhesive

station 15 further. The distance of the glue station 15 from the The moistening station 9 is dimensioned so that, when an album sheet 2 is correctly positioned in the gluing station 15, at the same time Another album sheet 2 is also correctly positioned in the moistening station 9.

The gluing station 15 is constructed similarly to the moistening station 9. It also contains one towards the rear of the album sheet 2 and back away from her by a piston cylinder 16 actuated movable counter-pressure plate 17 and a Base plate 18 on which the piston cylinder 19 can slide towards and away from the printing side of the album sheet 2 Magazines 20 for the protective pockets 1 are arranged.

The moistening station 9 shown schematically in FIG. 2 consists of a cylinder housing 21 with two displaceable through one arranged piston 22 separate chambers 23 and 24 with variable volume. In each chamber 23, 24 leads an inlet or outlet connection 25 for a drive means. The piston 22 is on one side with one through the housing 21 guided piston rod 26 which contains a bore 27 at its free end into which a corresponding projection 28 of an upwardly open container 29 can be locked, e.g. by means of a locking screw. Through this there is the possibility of simply exchanging the container 29 when the size of the field to be moistened changes.

281953Q

The container 29 fills a humidifying insert 30 protruding from its upper edge, preferably made of a porous one elastic material, via a closable nozzle can be a supply line 32 (Fig. 7), which is connected to a central distribution container 33 for water or an adhesive is to be connected to the container 29.

Through the line 32, the container 29 can be continuously refilled with water or with the adhesive, so that always the same moisture or: w. Amount of adhesive can be transferred. The distribution container 33 is arranged to be adjustable in height so that it is always in the container 29 to ensure the same level. The humidifier 30 can be made of any porous material, such as ceramic, rubber, plastics, felts, woven fabrics and the like. Any known liquid or film-coatable adhesives, e.g., adhesives, can be used as the adhesive plastic-based such as polyvinyl acetate or animal hot glue, etc., can be used more.

Another embodiment is that on the container 29 cover plates 35 provided with openings 34 are placed on the opening of the container 29 and, for example, through Tongues 36 on the cover plates 3 5 and grooves 3 -? - on the container be attached to it. This is advantageous if smaller fields are to be moistened, because then not the entire container 29 must be replaced.

The magazine 20 shown in Fig. 3 with the associated piston cylinder 19 of the gluing station 15 has a corresponding one Basic structure like the moistening device 14 with associated piston cylinder 13. Instead of the container 29, however, is in the bore 27 'an exchangeable base plate 37 with a projection 38 is inserted. The size of the base plate 37 corresponds the size of the pockets 1 to be glued on or is smaller than that of the pockets 1. At least two opposite one another Edges of the base plate 37, in any case at those which are perpendicular to the direction of movement, are parallel to these edges on the cover plate of the cylinder housing 21 Side walls 39 are arranged such that they can be displaced and locked, which form one of the side walls of the magazine 20. The other side walls can by also on the cover plate of the housing 21 'displaceable and lockable round mandrels 39' (Fig. 4) or narrow strips are formed. This has the advantage that when changing the size of the pockets 1 only the Side walls 39, 39 'against the stack of bags 1 with others Format must be pushed in and locked under Under certain circumstances it may also be necessary to replace the base plate 37.

Provided that at least one mandrel 39 ', but preferably two mandrels 39', is arranged displaceably on each side of the base plate 37 are, and the base plate 37 slotted on the displacement paths of the mandrels 39 'according to the mandrel diameters also needs to change the size of the pockets

909 8AS / 0A4B

Bottom plate 37 does not need to be replaced and there are only the mandrels 39 'on the side surfaces of the new stack of pockets 1, depending on the size of the pockets 1, some of the mandrels 39 'inserted into the slots will. The walls 39 or the mandrels 39 ′ have a foot part 40 resting on the cover plate of the cylinder housing 21 ′ with a slot 41 (Fig. 4). On the cover plate, a threaded bolt 42 is attached, which is dimensioned so that it enters the slot 41. It is fastened by means of a knurled nut 43 that can be screwed onto the threaded bolt 42 (Fig. 3). ■

The magazines 20 can also have the shape shown in FIG. 9. Here, too, each base plate 37 is on a piston cylinder 19 arranged. However, the magazine walls are formed by two corner pieces 46 that are directly on the Base plate 18, e.g. held by magnetic force. One leg is made stronger for better holding. In one of the legs 47 of each corner piece 46 is a spring 49 sprung, arched at the top Plate 50 embedded. This plate 50 protrudes slightly beyond the edge of the magazine. On the other leg 48 a projecting leaf spring 51 is arranged above, which serves as a stripping edge and ensures that during a gluing process only one pocket 1 is pulled from the stack. By the leaf spring 51, the passage opening is reduced so that when the top pocket 1 is lifted, it is bent.

- 19 - "281953

whereby it detaches itself from the pocket 1 below it. To prevent the lower pockets from slipping sideways 1 to prevent the uppermost pocket from being lifted off, the spring-loaded protruding plates 50 are used.

As indicated in FIG. 3, the side walls 39 can have a fixed beveled edge 51 'protruding into the magazine 20 at the top. have which, like the leaf springs 51, also serve for isolation.

The bottom of the cylinder housing 21, 21 'or the base plates 12, 18 can contain permanent magnets or electromagnets, the other part being made of steel or iron. This makes it possible, the cylinder housing 21, 21 'and thus to position the moistening devices 14 and the magazines 20 as desired on the base plates 12, 18. Preferably In this case, the base plates 12, 18 have grid lines 43 (FIG. 8) for easier directional displacement of the cylinder housing 21, 21 "on them, these having at least one right-angled contact edge.

The cylinder housings 21, 21 'can also be removable, displaceable and optionally lockable on parallel on the base plates 12, 18, removable, displaceable and optionally lockable arranged rails 44 (Fig. 8) are arranged.

Another possibility is the cylinder housing 21,21

909845 / OUS

mechanically, e.g. by clamps, vices or claws using spacers or the like on the Base plates 12, 18 to be attached.

Another embodiment partially shown in FIG is that instead of an abundance of individual piston cylinders 21, 21 'for the movement of the moistening devices 14 or the magazine 20, only the base plates 12, 18 of which can be moved up and down by piston cylinders 45, i.e. the piston rod 46 is directly connected to the base plate 12, 18. In such an embodiment, it is advisable to use of the moistening station 9, the moistening insert 30 is somewhat stronger to let protrude over the edge of the container 39, which in addition to better moistening (by pressing out) also damping can be effected. The counter-pressure plates 11, 17 and the base plates 12, 18 are then also preferably on the piston rods of their piston cylinders 10, 16, 45 releasably attached, i.e. interchangeable. This is on the one hand a quick replacement of prepared base plates 12, 18 in the case of differently designed album leaves 2 and easy adaptation to other sheet formats possible.

In the case of the gluing station 15, it is advantageous in this embodiment to place the wall around the base plate which can be displaced in it 37 to train closed and necessary to cushion this so that when the magazine 20 is completely empty and in the top working position extended base plate 37 the

The wall cannot protrude beyond the base plate 37. Between the piston rods 26, 26 'and the containers 29 or the base plates 37 can have damping or spring inserts (not shown) are arranged. The counter-pressure plates 11/17 preferably have elastic coverings 11a, 17a.

Another embodiment of the humidifying device 14 shown schematically in FIG. 5 consists in that ^{a continuous humidifying support 52 is provided on the extendable base plate 12 1} , which is covered by a mask 53 (FIG. 6) with windows 54. The size and number of the windows 54 corresponds to the size and number of the fields to be moistened on the album sheet 2. The base plate 12 'can be provided with connecting pieces for supplying the moistening agent and with a network of ducts for evenly distributing the moistening agent in the moistening support 52. This channel system (not shown) can also be designed as an independent component of the moistening station 9 or incorporated directly into the moistening support 52.

Instead of a dampening pad 52, when using a Mask 53 also applies the dampening agent over a support, e.g. one or more rotating, optionally movable brushes, rollers, rollers or belts can be provided, with one Some of them are immersed in the moistening agent and wipers are provided on the way to the mask to ensure that they are even To ensure order. In Fig. 11, one contains

S09845 / 0U5

Moistening device 14 has two rollers or rollers 55 over which an endless belt runs as a moistening insert 30 ″. The lower path of the endless belt dips into the moistening agent a. The moistening agent can also be sprayed through nozzles as a moistening insert 30 "'(FIG. 7), with masks 53 may or may not be provided.

When the album sheet 2 which has come into the gluing station 15 comes to a standstill, the piston cylinders 16 move the counter-pressure plate 17 and the cylinder 45 or the cylinder 19 of the magazine 20 and clamp the album sheet 2 between them. As a result, the protective pouches 1 lying on top of the magazines 20 come with the protective pouches applied to them, if applicable Adhesive layer under pressure in contact with the moistened or adhesive-provided fields of the album sheet 2, whereby the respective uppermost pockets 1 adhere firmly to the album sheet 2. If necessary, the extended piston rods Remain in this position for a moment to strengthen the connection; then they move to the starting position return.

If only the base plate 18 of the gluing station 15 is and is retractable, first the upper edge of the sprung wall of the magazine 20 comes against during the upward movement the album sheet 2, then the counter pressure plate 11 so is extended quickly so that the album sheet 2 is pinched from both sides at the same time. Only then can it

90984S / 0445

-23- 2813530

the base plate 18 is further extended until the uppermost pocket 1 is in contact with the album sheet 2. Here are the base plates 37 of the magazines 20 are cushioned relative to the piston rods carrying them to avoid possible irregularities to be able to compensate for the filling of the individual magazines 20.

As soon as the cylinder of the base plate or the counterpressure plate releases the album sheet 2 on their way into the starting position have, it is transported by the conveyor 8 one cycle further to the output station. Here, for example, the interaction of an upwardly and downwardly movable cam 56 with the catches of the snap-action grippers 5, so that the finished album sheet 2 is released. In the embodiment shown in Fig. 1, the exit station is after a deflection roller 7 of the conveyor 8 is arranged so that the album sheet 2 no longer rests on the conveyor parts, but only hangs in the snap gripper 5, so that it after releasing the snap gripper 5 due to gravity, if necessary by means of a slide or other guides ends up on a discard pile.

A known scanning and sorting station for checking the protective bags can be installed between the output station and the discard pile 1 provided album sheets are arranged for completeness, whereby the incomplete sheets are separated out will. This can be done optically by light rays or mechanically

§09845 / 0445

. 24 -

2819Ö3

done by scanning. So that two pockets do not stick to one field, nozzles can be provided which are longitudinal blow one or more lines of compressed air diagonally against the album leaves.

The device is controlled so that from cycle to cycle simultaneously an album sheet 2 gripped by the snap gripper 5, a second moistened or provided with adhesive, a third equipped with pockets 1 and a fourth is released from the snap gripper 5 and thus from the device. this has the consequence that the distances between the individual stations must be the same. If necessary, you can several moistening or gluing stations can be arranged one after the other. This may be necessary when the bags must be arranged very close to each other. The cylinders can be operated hydraulically or pneumatically and is automatically controlled by known control systems.

Another embodiment, not shown, is that a turntable is used as a conveyor. Here the individual stations such as take-over, moistening, gluing, if necessary alignment, control and exit station are on arranged in a circle at equal distances from each other. Each station is assigned a holder who is responsible for the function of the Snap gripper, i.e. the centered retainer and transporter of an album sheet while it is being processed in the device and the function of the counter-plates in itself

984 ^ / 0445

-25- 281953Q

can unite. This can be done by the size of the album sheets corresponding plates, which are on a circle around the Axis of the turntable are movably arranged, in which fine continuous channels are executed from one side can be connected to a vacuum source and to a compressed air source at the discharge point. The respectively aligned Album sheets are picked up at the transfer station by a Lowered holder sucked in by means of a vacuum, through the device transported to the individual processing stations and at the output station by compressed air flowing through the channels is blown in the plates, blown off. In such an embodiment, the moistening devices need or also the magazines do not necessarily have their own drives for moving up and down, springs would be sufficient here, if the holder against appropriately cushioned dampening stations or magazines are extendable.

In the described embodiments, the album sheets fed to the individual processing stations, but it is just as possible to fix the album sheets and the processing stations movable to be arranged on conveyors, it is also possible, the base plates with the moistening and glue stations for quick change to be arranged as exchangeable exchangeable cassettes, e.g. movable on rails, as indicated in FIG. 1.

909845 / Q44S

Another variant, especially for the moistening station is shown schematically in FIG. Here is a base plate 12 'that is not only movable up and down, but is additionally movable to and fro either in the conveying direction or perpendicular thereto. The single ones Moistening devices 14 arranged thereon contain only narrow gaps, in each of which a felt is used as a moistening insert 30 'is arranged. It is also possible to provide only one rotatable roller immersed in the moistening agent. By moving the base plate 12 'extended into the working position in one of the horizontal directions moistened the felt or by unrolling a roll a strip.

The exemplary embodiments provide some specific embodiments reproduced. It is understood that some of the features described in one embodiment can also be combined in combination with features of other exemplary embodiments.
