US 4,988,086 discloses an apparatus and method for forming Sheet material compilations. This device includes a variety of Collating elements that circulate on a continuous path and the Move one after the other under a stack of sheet material. The stack of sheet material are in bottomless magazines. The gathering elements are ribbons assigned to support the sheet material stacks in the bottomless magazines. The Bands move with the gathering elements and capture them one after the other Stack of sheet material. The upper runs of the tapes move in opposite directions with respect to the collating elements and with the same Speed like the collators so that the top runs of the tapes are stationary relative to the stacks of sheet material. The sheet material gathering elements are also feed mechanisms and pick-up stations assigned. When a collator is under a stack of sheet material is moved, the sheet is fed from the sheet material stack to the sheet by a feed mechanism Recording station moves.

It was found that when stacking sheet-like products in stacks it is not possible to carry out processing steps such as printing on the products in the Perform inkjet processes before the products go from the stack to the pickup station to get promoted. Furthermore, it is difficult to separate products from a stack remove. In addition, the products are fed onto a stack, for example from a product roll (print roll), which is the sheet-shaped products in one Dandruff current supplies, disadvantageous since the next product to be supplied may be must wait a thousand strokes to be selected, which is greasing or some other degradation of the quality of one at the bottom of the stack lying product.

The solution according to the present invention has a number of advantages. Since the sheet-like products can be fed in a shingled or overlapped form a large part of the overlap can be used as a time cycle in which the Deflectors take their activated position before they hit a particular one Leading edge part of one to be fed into a predetermined collecting bag deflect the arcuate product. The overlapped route allows the Deflecting elements to remain in their activated position for a sufficient time, so that the leading edge part of the picked product is sufficiently far into the respective one Collection bag is introduced.

According to another feature of the present invention are in various places arranged along the path of the collecting bags feeding stations, which is a sequential Allow sheet-shaped products to be fed into individual collection pockets. The feed stations have a section that is parallel to the direction of movement of the collecting pockets and thus the feed area of a series of Covers collecting bags at the same time. This section can counter the products Transport direction of the respective collectibles move and represents a number of Products within the conveyor level above the collecting bags. The funding level runs between the section of feed stations that is parallel to the Direction of movement of the collecting pockets extends, and the surface of a respective Collection bag.

The collecting bag surfaces are surfaces of tapes that oppose each other Move the direction of movement of the collecting bags. Each collection bag also includes Deflection element that is in the conveyor plane between the above. Section of the feed station and the surface of the respective collecting bag is movable. The deflectors, the can be blade-shaped or roll-shaped elements Actuating components, such as axle shafts or movably mounted supports, so that they can move relative to the collection bags.

In one embodiment of the present invention, the deflection element is on a Actuating shaft attached and takes one parked or one employed Position. In its parked position, the deflection element closes a gap Collection bag so that the arcuate product moves on the conveyor plane. When the deflector is in the employed position, i. H. if it is the Blocked conveyor level, the respective leading edge of an arcuate product is in deflected a respective inlet portion of a collection bag. Another Embodiment of the present invention enables the deflecting member to be a Sliding movement on a support that is carried out by a modified actuating shaft is activated, the actuating shaft of a separate drive or Control cam arrangement is driven. According to a further embodiment of the Invention, the deflecting element is a roller-shaped element that when in contact with circumferential bands on a collecting pocket forms a pressure gap. If the The leading edge part of a product is caught by the pressure gap, this moves roller-shaped deflecting element in a direction in which the entry of the respective Leading edge part of the product into the gap of an inlet portion of a collection bag he follows.

At the feed station along the transport path of the collating system is arranged, the arcuate products between a conveyor belt section and an associated counterband arrangement in a shingled stream. At the There is a foot of the feed belt section and the counter belt arrangement Release section through which the arcuate products extend into the respective top move mentioned funding level.

Fenster" verwendet werden. Das Ablenkelement 13 bleibt solange in seiner angestellten Position 13.2, bis die Vorderkante 4.1 eines Produktes 4 in den Spalt 14 eingeführt ist.The deflection element 13 in its adjusted position 13.2 shown in FIG. 3 can be moved into its parked position 13.1 long before it picks up the front edge 4.1 of the next arcuate product 4. This can be achieved because the sheet-like products 4 are conveyed with their leading edge 4.1 lying on the respective next product 4. Thus, the overlapped distance within the incoming stream of arcuate products can be as one

The deflecting element 13 remains in its adjusted position 13.2 until the front edge 4.1 of a product 4 is inserted into the gap 14.

In Fig. 4 is a feed station 10 for feeding sheet-like products in one shingled stream shown on which the deflecting elements exert a sliding movement, such as this is indicated by the arrows 35.

According to this embodiment of the invention, the feed station 10 includes one Feed belt section 28. A portion of section 28 extends parallel to and adjacent the respective upper run of the tapes 9 of the collecting bags 7. This part of the Band section 28 moves against the direction of movement 2 of the plurality of Collecting bags 7. This ensures that a number of products 4 is present in the conveying plane above the surfaces 9 of the collecting pockets 7. A shingled stream 30 of arcuate products 4 becomes the feed station 10 in fed perpendicular direction and between the belt section 28 and one associated counterband arrangement 31 detected. The tapes are around each Guide rollers 32 and 33 guided to the arcuate products 4 to a release part 29 to be conveyed between the feed belt section 28 and the counter belt arrangement 31. If the products 4 appear in the release part 29, they are replaced by a Guide roller 32 of relatively large diameter in the conveyor plane, which is between the lengthwise feed belt 28 and respective surfaces 9, i.e. H. the upper runs of the driven belts 9 of the collecting pockets 7 runs, steered into it. At this point in the conveyor level, the orientation of the product front edges is 4.1 such that each leading edge 4.1 is arranged above the previous product 4.

The deflecting element in the embodiment of FIG. 4 is a blade-shaped Element 27, the tip of which slides as indicated by arrow 35 indicated, moved into the conveying plane of the arcuate products 4, d. H. in the Intervention level intervenes. The deflection element 27 is close to the respective guide roller 21 Collection bags 7 arranged. The deflection element 27 is actuated by a Sliding movement of a prop. This sliding movement can be done either by a drive or a cam arrangement, which are not shown in detail, can be initiated. In 4 are the deflection elements 27 of two collecting pockets 7 activated, d. H. they engage in the conveying plane of the arcuate products 4 and direct a respective product part into the interior of a respective collecting bag 7.

4, an arcuate product 4 is almost completely in the collecting section 15 the middle collecting bag 7 occurred. Only the upper part of each Collection bags 7, d. H. the belt 9 and the deflection element 27 arranged at the front end of the respective collecting pockets 7 are shown in Fig. 4.

The shingled product stream 30 emerging from the release part 29 is into the an arrow indicated direction 34, which indicates the feed belt section 28, promoted. The conveying speed of the shingled product stream 30 differs the speed of the belts 9 of the individual collecting pockets 7.

Another embodiment is shown in Fig. 5, in which a roll-shaped Deflection element 38 moved planetarily about an axis of rotation. Here is the difference Feed station 10 is not significantly different from feed station 10 of FIG. 4. Instead of one is rotatably or slidably attached deflector 13 or 27 here roller-shaped deflection element 38 fastened to a lever 37 and relative to the lever 37 rotatable around its own axis. The lever 37 moves about the axis of rotation 36 one Tape idler 20 counterclockwise as shown in FIG. 5. The Deflection element 38 can move from a position in which it is connected to the tape guide roller 20 in Contact is - as shown for the collecting bag on the far right in Fig. 5 - to Position of the dashed line above the idler 20 - as for the next to the outside right-hand collecting bag shown in Fig. 5 - move. In his position about the guide roller 20, the deflecting element 38 forms a gap between the belt 9 and the Surface of the deflecting element 38. A product leading edge 4.1 conveyed, and the roller-shaped deflector 38 moves radially outward with respect to the center or the axis of rotation 36 of the guide roller 20. At one Rotary movement of the deflection element 38 counter to the axis of rotation 36 of the guide roller 20 the deflection element 38 rotates clockwise on the respective belt 9 and steers thus the respective product front edge 4.1 in the gap 14 of the respective Collection bag 7 into it. The rotatable lever 37 moves the deflection element 38 in the opposite direction clockwise (as shown in Fig. 5) around the idler 20 and thus moves the arcuate product 4 into the respective collecting pocket 7. The roll-shaped Deflection element 38 is not rotated about its axis by a separate drive, but the rotation around its own axis is caused by the contact of the Deflection elements 38 with the belt 9, which is driven by the belt drive shaft 11 is generated.

In the embodiment of FIG. 5, the aforementioned drive shaft 12 is in the Modified that movement of the lever 37 uni the axis of rotation 36 Guide roller 20 regardless of the tape drive shaft 11, the guide roller 20 and their Bands 9 is assigned takes place. The distance between the successive Collection pockets 7 and the diameter of the deflecting element 38 are selected so that at a movement of the deflection element 38 about the axis 36 of the guide roller 20 by approximately 45 ° there is no intervention in the subsequent collecting pockets 7.

According to the embodiments of the present invention, using of the different deflection elements 13, 27 and 38 the distance of the overlap between the arcuate products 4 serve as a functional window in which a Deflecting the leading edges of the products 4 can be carried out without the conveying process of the to affect the scaled product flow. In addition, a scaled increases Product flow productivity because feed speeds are high and frequent Stop-and-go operations can be avoided.
