Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for processing accumulated paper sheets during the production of a sticky bound thick bound paper piece and a thick bound paper piece.

[0002]

2. Description of the Related Art A sticky binding thick-stitched paper piece made of double paper sheets folded along a fold, which is later attached to a folded side and connected by a binding, is an individual paper sheet cut made of material sheets. After being folded and collected, it is usually carried after being placed on a conveyor with the folding side forming the back part facing backward. In this case, the glued-on heavy-duty paper strips usually have various useful widths which fit the width of the material sheet. The glued-on paper strips are then picked up by a transverse conveyor and finally the front is squared and separated into individual paper-stitched paper sheets. This is usually done after laminating and optionally still stiffening or attaching the ear bands.

From DE 1008708 is known a turning device used for helically bound products. The device consists of six stowage positions with cam-controlled clamping devices, an orienting station in which the row of perforations provided for spiral binding enter the row of keys,
It has a spiral winding station following which the spiral wire is screwed into the row of perforations and a delivery station to an unloading conveyor which is further conveyed in the conveying direction. The bindings and the backs provided for them each have an outer side in contact with the turning device, which enables processing from the outside.

[Means for Solving the Problems]
4) A folded double leaf (12) is produced from at least one material sheet, in particular a paper sheet, along with 4) and is folded up and down at folds (14) so that the deposited leaf (15) is substantially horizontal. First, from the fold (14) to the storage bag (2
4), close the storage bag there and tighten it, rotate and place it in a substantially vertical position, and in this state stand up at the fold line (14) to loosen or release the tightening and then perform a butt alignment movement. Then, with the closed storage bag (24), the storage bag (24) is rotated to a substantially horizontal position in a direction opposite to the direction in which the storage bag (24) is placed, and the accumulated paper sheet is moved relative to the capturing device (40). Bag (24) by moving it to engage the capture device.
Is opened, the catching device (40) being solved by carrying out the pile of paper sheets (15). From the back of the back, first, the pile of paper fed to the turning device on the conveyor is tightened in this turning device, rotated to an essentially vertical butting position, where the tightening is loosened, and then in the storage bag. The folds are vertically aligned and butt-aligned with each other, so that the folds are accurately aligned with each other. Subsequently, the accommodating bag is closed again and rotated to a horizontal carry-out position, and the piled paper sheets are turned and arrive there. The piles of paper are then clamped in the storage bag, the individual paper slides are prevented from sliding and are delivered to a catching device which clamps the pile of paper again before the bag is opened. For that purpose, the bag can be slid radially outwards inside the turning device.

This is achieved without cutting the spine of the piled paper sheet with folds anymore, so that the bound paper sheets are still grouped as double paper sheets, improving the collective holding of the entire binding section. In particular, various actions (storage, butt alignment, delivery) that are intended for successive storage bags can be performed in time synchronization with each other so that the storage bags can be opened and reclosed simultaneously. Thus, it is possible, for example, to process with a pneumatic opening and closing drive which is supplied only in the turning device via a pneumatic conduit and is controlled by an eccentric control device.

The device according to claim 7 is also useful for solving the problem. This device consists in particular of a turning device with four storage bags. In this turning device, an eccentric butting device for the front and side edges can optionally be arranged above the central part. The bags should still be bound while the storage bag is moving relative to the catching device of the unloading device in order to deliver without the risk of sliding of the individual sheets. For this purpose, the storage bag can be moved with its closing device on a radially arranged linear guide. This linear guide feeds the closed storage bag via a feed drive until the catching device receives the stack of sheets and carries them out in the longitudinal direction.

The present invention further proposes a thick bound paper piece that is stuck and bound. The sticking and binding thick paper strip has a stack of double-leaf sheets folded along the fold line. The double leaf has perforations along the fold line. If the glued ties are provided along the creases, the adhesive can first be partly inserted into the perforations and thus directly with the individual double leaf, i.e. at the folding position provided by the double leaf. Can be combined. In this way, it is very easy to peel off the sheet from the adhesive on the one hand, and on the other hand, the difficulty of opening the sheet to the end without having to feed the adhesive back into the sheet.

A product which is easy to open, flexible and tightly bound is thus produced with good orientation of the back area of the fold. The above configuration and configurations other than the above are apparent from the claims, the detailed description, and the drawings, and these individual configurations may be used by themselves or in some sub-combinations, embodiments of the present invention and other fields. It is possible to construct an embodiment which is realized and advantageous in itself and which can be protected by itself, for which protection is claimed.

The division into individual chapters and intermediate titles in this application do not preclude their general relevance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in the drawings and will be described in detail below. FIG. 1 shows a part of an apparatus for manufacturing the thick-binding paper pieces 11 that are stuck and bound. In this machine, in front of the area shown in FIG. 1, a sheet of material 12, for example a sheet of paper, is cut into double sheets (FIG. 2) and the attachment line of perforations 13 is formed in the center. It is provided and folded along the crease line 14 coinciding with the perforation line and put together. The double paper sheets are stacked one on top of the other at the folds 14 to form a stacked paper sheet 15, and in some cases, a cover sheet 16
After placing (Fig. 3) a horizontal conveyor 17 in the form of a table
It is mounted in a transport direction 20 (from left to right) by a sliding element 18 guided along a circulating chain 19 and is transported to a turning device 21.

The conveyors are each horizontal and rotatable about an axis 22 extending with respect to the conveying direction 20 by 90 ° by a step drive, not shown. The conveyor has four storage units 23 which are offset from each other by 90 degrees. Each of the storage units has a storage bag 24. This storage bag is adapted to the size of the accumulated paper sheet 15. It should be noted here that the pile of sheets along the turning device has a much larger transverse dimension than the other, subsequently completed, thick-stitched strip. These piles of paper consist of several utilities which are later separated from one another for the formation of individual cardboard sheets.

A closure device 25 is provided in the area of each storage bag 24. This closing device consists of a pneumatic cylinder 26 and a clamping element 27 connected to its piston.
The pneumatic cylinder is connected to a central pneumatic conduit 28 at the boss 29 of the turning device by a pressure hose not shown. The bottom of the storage bag, which is bounded on the sides by two plates which act as guides, forms a butt face 30. Each storage bag 24, including the closure device 25, is arranged on a slider 31 which slides by a linear guide 32 radially towards the turning device, i.e. outwards in opposition to the force of a spring 33. can do. Two-arm type operating lever 34
Acts on one of its ends on the slider 31 and in the corresponding actuation of the other end 35 with the roller slides the storage bag radially outwards by a predetermined amount in order to resist the force of the spring 33. Can be made.

The turning device is rotatable by 90 degrees between the following positions. That is, the storage position 36 where the storage bag is horizontally connected to the conveyor 17 which is approximately at the height of the axis 22, and the butt alignment position 37 where the storage bag is oriented almost vertically.
And a delivery station 38 that faces the storage position on the diameter in the transport direction and is connected to the carry-out conveyor 39. The carry-out conveyor 39 has a catching device 40 having a mushroom-shaped catching member 41. The capture member consists of a vertically moving shank and a wide head. When the head of the pile of paper sheets moves downward, the head can clamp the pile of paper sheets 15 on the conveyor 42 that moves laterally with respect to the transport direction (axial direction 22).

The cam 4 along the delivery station 38
A lever 44 is provided which is actuated by 3. This lever can act together with a roller contacting the end 35 of the actuating lever 34 and guide the slider 31 into the guide 3.
2 can slide in the direction of arrow 45 towards the capture device 40. At that time, the front edge portion 46 of the accumulated paper sheet 15
Extends beyond the outer rotating circle 47 that has been maintained until now.

At the butt aligning station 37, the stack of paper sheets 1
A cam-controlled ramming lever 48 for the leading edge 46 of the five is provided. The lever optionally stands on the abutting surface 30 at the fold line 14, a double stack of stacked sheets 1.
It can also be connected to a vibrating device so as to make two butts. Before and after the drawing, a butt alignment device can also be provided for the side edges of the stack of sheets, which face away from the observer.

The fourth station, in which the storage bag is directed downwards, has no special function and only serves to return the storage bag to the storage station. The thick-binding paper piece 11 shown in detail and extremely enlarged in FIG.
2 (see FIG. 2). The leaves 48 connected along the fold line 14 are stacked one above the other. A reinforced cover sheet 16 of cardboard or the like is mounted on each side, one sheet each.

The double leaf 12 is overlaid with the folds 14 thereof and the edge 49 of the cover sheet exactly aligned to form the thick bound paper spine 50. It can be seen that the perforations 13 provided exactly in the crease lines 14 and the folds at this location are also facilitated. At this point, the folds are slightly open on the outside and pressed together on the inside. The perforations thus form a hopper-like opening and allow the penetration of the elastic adhesive 51 forming the back. In this way, the effect that the leaf 48 is better attached to the back is obtained. In that case, the perforations 13 will still rupture some of the tissue of the paper, thus further enhancing the adhesive effect. Each sheet 48 is not directly attached to the sheet of its associated double sheet 12 but also individually to an elastic adhesive layer 51, which may consist of, for example, thermoplastics, cold glue or polyurethane adhesive. be able to. In that case, it is advantageous that the adhesive does not have to penetrate deeply into the gap 53 between the two double-leafs in order to maintain the holding, so that the leaves are glued less widely during the opening of the thick-leaf paper. In addition, the thick paper strip can be used up to the back.

To cover the adhesive back 51, a fold band 52 is glued over its periphery and over the edge region of the cover sheet 16. The fold band can be composed of fibers or plastic-like pieces. Function It has already been described that the method for producing the piled paper sheet and that the piled paper sheet is conveyed to the turning device. The stack of sheets is pushed on the table of the conveyor 17 by the sliding element 18 into the storage bag 24 in the storage station 36. The closing device 25 is then actuated, in which case the pneumatic cylinder 26 is commanded to close and the clamping element 27 clamps the pile 15 in a storage bag slightly larger than the thickness of the pile. The width of the storage bag, that is, the width of the guide plate that divides the storage bag is set according to the thickness of the accumulated paper sheets.

Next, the turning device is rotated in the rotation direction 54 (clockwise direction).
Rotate 90 degrees. Then, the position of the leaf comes up vertically. An exact vertical position is advantageous, but some tilt position can be taken. Intermediate stations can also be attached, which then turn into eight-direction radial turning devices. The compressed air is expelled from the pneumatic cylinder 26 and the closing device is opened, so that the stack of sheets loosely lands on the butt face 30 at the bottom of the bag. The ramming device 58 is brought closer to the leading edge 46 by the cam 59 and exerts its ramming action in a known manner. The butt alignment action is assisted by the vibration. The same is done on both sides of the pile 15 which joins the leading edge 46 and the spine 50.

The closing device is then actuated again so that the stack of sheets is aligned with the folds in the spine 50 and the double sheet 1
2 is securely fastened in this state by 2 and is conveyed again to the delivery station 38 by rotating again in the direction 54 by 90 degrees, and is turned there, and is carried out forward by the front edge portion 46 which is behind in the conveyance direction. It is directed to the conveyor 39.

The cam 4 holds the accumulated paper sheets in the storage bag.
It is still maintained when the storage bag 24 is pushed radially outwards via the lever 44 and the actuating lever 34 by the rotation of 3, so that the edge 46 now projects beyond the rotation circle 47 and catches the mushroom. It is pushed under the head of the member 41. The mushroom-shaped catching member is closed by lowering its shaft. At the same time, the closing device 25 is opened, and the single-wafer position is then discharged transversely to the conveying direction up to now, that is, in the direction perpendicular to the drawing of FIG. There, adhesive is applied to the aligned backs, the folds are carried and the piles of paper are cut into individual thick-stitched sheets.

The empty storage bag 24 is returned to the storage station 36 again in the next step via the intermediate station directed downward. Each function is 3
The three storage bags at one work station 36 to 38 can be synchronized with each other so that they can be opened and closed simultaneously. The pushing in at the storage station, the collapsing at the collapsing station and the removal of the stack of sheets by the catching device 40 are carried out simultaneously, the closing device being open, i.e. in the non-clamping state, while each time individually. Radial outward sliding at the transfer and transfer stations between the stations also occurs when all the storage bags are closed. In this way, the pressurization and unloading of the pneumatic cylinders 26 of all the storage bags can be carried out via the central conduit from a central controller provided outside the turning device.

It will be appreciated that the device is capable of diverting the sheet layers and at the same time aligning the sheet layers. What is particularly remarkable is that the single-wafer layers are guided so as to always be positively fixed after butt alignment, i.e. the single-leaf layers do not cross each other again after butt alignment. This butt alignment allows the fold line 14 to remain uncut, thus improving the quality of the thick-sheet paper. In addition, material is saved by not generating wastes at this portion. The work of cutting the individual pieces of heavy-duty paper into corners later is also reduced by improving the alignment. This also leads to material savings.

[0025]

The effect of the present invention is that complete bundling can be performed during the production of the stuck and bound thick paper sheets with minimal material consumption.
