Definitions

• the invention relates to a device and method for laying out flat objects by means of a conveyor line according to the preamble of claim 1 or 25.
• Such a delivery device is used in particular at the exit of a rotary printing press in order to lay out individual signatures from a strand of printed paper webs onto a plurality of conveyor belts.
• a known delivery device of this type is e.g. B. described in DE 101 16 346 A1.
• This known device uses conveyor lines, in which a signature is conveyed clamped between endless belts, each of which is wound around a plurality of rollers. To distribute the signatures to different delivery points, the conveyor line is forked several times, and there is a signature switch in the form of a reciprocating wedge at each fork, which, depending on the position, deflects a signature that passes through it in different directions and thus to different branches of the conveyor line leads.
• the signature switch In order to distribute a stream in two different ways using such a signature switch, the signature switch must be able to change its position between two passages of signatures. This is only possible if the signatures do not follow one another immediately. If the signatures are cut from a continuous web, such a distance between the signatures can only be achieved if the speed of the conveyor line is significantly greater than that of the web before cutting. The smaller the distance between two consecutive signatures at the switch, the faster it must be able to switch. This leads to considerable demands on the mechanics of the signature switch, which only requires considerable technical effort and corresponding costs are to be met.
• the invention has for its object to provide a device and method for laying out flat objects by means of a conveyor line.
• the device manages without quickly and discontinuously moving parts, such as the signature switch described above.
• large distances between objects consecutive on the conveyor line are not required in order to be able to feed these to different delivery points without problems.
• the paddle wheels are preferably arranged on one side and / or below the conveying path, so that the objects conveyed on the conveying path tend, due to their own weight, to penetrate into a compartment of a paddle wheel if this is possible.
• a tip of each blade that crosses the conveyor line, while the compartment formed by the blade adjoins the conveyor line, serves to intercept the front end of an object, which is located on the conveyor line at the level of the compartment of a paddle wheel, and into the compartment distract.
• the peripheral speed of the blade is lower than the conveying speed of the conveying path.
• each blade wheel has only a single blade.
• Two blades per blade wheel can also be provided, since this simplifies the balancing of the blade wheels and, compared to the case with a single blade, does not significantly increase the circumference of the blade wheel makes necessary.
• Adjacent paddle wheels preferably have a phase shift of 2 ⁇ (d / vT ⁇ 1 / mN), where d is the distance between the paddle wheels, N is the number of paddle wheels, m is the number of their paddles, v is the conveying speed of the conveyor section and T is the time interval between two objects conveyed on the conveyor line. This phase difference ensures that two objects conveyed in succession on the conveyor device are alternately taken over by the n paddle wheels.
• the number N of the paddle wheels is preferably four. If the device is used in connection with a printing machine whose plate cylinder can accommodate four plates or printed images in the circumferential direction, the device with four paddle wheels allows printed products printed from the same plates or having the same printed images to be laid out at the same delivery point, and thus the printed products that cyclically follow one another on the conveyor line.
• the device is used for printed products, it is preferably preceded by a cross-cutting device that breaks down a printed material web or a strand of material webs into individual printed products.
• a vertical section of the conveyor line is preferably arranged downstream of the cross-cutting device and can be used to space the individual printed products supplied by the cross-cutting device on the conveyor line.
• the paddle wheels are preferably arranged on a horizontal section of the conveyor path in order to facilitate the deflection of the products into the compartments of the paddle wheels.
• Figure 1 is a schematic section through a device.
• FIG 3 shows a modification of a paddle wheel for the device.
• An input of the device shown in Fig. 1 is through a cross cutting device 01, z. B. formed a pair of cutting cylinders 01.
• the cutting cylinder pair 01 is, as illustrated by an arrow, a strand of printed material webs z. B. paper webs supplied.
• a cylinder of the pair of cutting cylinders 01 carries a knife which, in cooperation with an abutment of the other cylinder of the pair of cutting cylinders 01, separates a section of one side length from the strand with each revolution of the pair of cutting cylinders 01.
• the object obtained in this way, in particular the printed product enters an input gusset 02 of a conveying path 03 which is closed by endless belts 06, z. B. conveyor belts 06 is formed.
• the rotational speed of the endless belts 06 is approximately 5% greater than the speed of the paper webs fed to the pair of cutting cylinders 01.
• the individual products are therefore gradually accelerated in the gore 02 of the conveyor line 03, which gradually narrows downwards, which results in a gap of approximately 5% of their side length between successive printed products.
• the initially vertical conveyor line 03 merges into a horizontal orientation on a roller 07 of large diameter.
• the function of the roller 07 alone the deflection of the conveyor line 03, but it could also be a collecting cylinder 07 known per se, on which each supplied printing product travels at least one complete rotation in a manner known per se, is combined with at least one further printing product to form a stack and finally as Stack is given for further promotion.
• the roller 07 can also be designed as a folding knife cylinder 07.
• the printed products delivered by the roller 07 continue to move on a horizontal section of the conveyor line 03, on which a number N of paddle wheels 08, here four, each with a single blade 09, are arranged one behind the other.
• the paddle wheels 08 are arranged at a uniform distance d from one another and rotate at the same speed, with a phase shift of 2 ⁇ (d / vT + 1 / N) between adjacent paddle wheels 08, where v is the speed of the endless belts 06 of the conveyor section 03 and T denotes the time interval between two successive printed products on the conveyor line 03.
• a section of the conveyor section 03 is arranged between two paddle wheels 08.
• This choice of the phase difference between the paddle wheels 08 ensures that whenever a printed product is located above a paddle wheel 08, either the compartment 11 of this paddle wheel 08 faces it, so that the printed product can enter the compartment 11, or the compartment 11 is offset by + 1/4 or a 1/2 turn, and that (depending on the sign) successively conveyed products either one after the other from the compartment 11 of the first, second, third, fourth and then again the first paddle wheel 08 or vice versa Order are adopted.
• the paddle wheels 08 are constructed from a plurality of essentially circular disks which can be rotated in a plane about a common axis of rotation, into each of which a compartment 11 is cut and which rotate at a circumferential speed is somewhat less than the rotational speed of the endless belts 06 and is preferably equal to the speed of the paper webs fed to the pair of cutting cylinders 01. Only the free end of each blade 09 protrudes a bit beyond the circumference of the circular disk, so that this free tip 12 crosses it in its position facing the conveyor section 03 (see FIG. 2).
• the tip 12 thus slightly deflects the trailing end of a printed product 13 upwards, while at the same time it is an obstacle to the leading end of a subsequent printed product 14 since it moves more slowly than the latter leading edge of the printed product 14 down, into the compartment 11, deflects. It is immediately clear that a large distance between successive printed products is not required to intercept the printed product 14 from the conveyor line 03 into the compartment 11. Rather, it is entirely desirable to have a very small distance between the printed products so that the printed product 14 is pushed as deep as possible into the compartment 11 before its trailing end loses contact with the endless belts 06 of the conveyor line 03.
• Prongs 16 of a fixed rake engage from below between the disks of each paddle wheel 08 in order to push any printed product contained in the compartment 11 of the paddle wheel 08 out of the compartment 11 in the course of the rotation of the paddle wheel 08 and on a delivery point 17, here a conveyor belt 17 moved transversely to the plane of FIG. 2.
• paddle wheels 08 Although only four paddle wheels 08 are shown in FIG. 1, it is obvious that the principle of the invention can be generalized to any number of paddle wheels 08 and delivery points.
• the number N of the paddle wheels 08 is an integer and can be greater than or equal to three. In general, however, it does not make sense to have more delivery points 17 than there are different printed products on the conveyor line 03 can. In other words, if the device is used in connection with a printing press, the plate cylinders of which can carry up to four different plates or printed images in the circumferential direction, then no more than four delivery points 17 corresponding to these four plates or printed images are useful.
• the roller 07 is a collecting cylinder 07 which is operated in the collecting mode and delivers printed products assembled from two stacked sections, this leads to a doubling of the period T with which the printed products pass the bucket wheels 08 compared to the non-collecting mode , Without a change in the movement of the individual paddle wheels 08 being necessary for this purpose, the collected printed products are each only laid out on two of the four delivery points 17.
• This modified impeller 08 has two blades 09 in diametrically opposite positions, and the tip 12 of at least one of the blades 09 is between the position shown in FIG. 2, in which it projects beyond the circumference of the circular plate of the impeller 08, and one in the lowered position, in which, as shown in FIG. 3 below, it does not protrude beyond the circumference of the circular disk and instead closes the compartment 11 on which it is arranged. If such a paddle wheel 08 is mounted, for example, in the position closest to the roller 07 in FIG.
• a paddle wheel 08 of the type shown in FIG. 3 is also mounted in the position adjacent to the roller 07 in FIG. 1, it is possible to choose between two, three or four conveyor belts 17. It is also conceivable to provide a paddle wheel (not shown) at the first position, which has four blades at a distance of 90 ° each, at least three of which have pivotable tips. When these tips are all swung out, such a paddle wheel intercepts all the printed products passing it on the conveyor line 03 and lays them out on its conveyor belt 17.
• the device accommodates identical first objects in the first impeller 08 and identical second objects in the second impeller 08, which differ from the first objects, identical objects in the third impeller 08 and identical fourth objects in the fourth impeller 08 which are identical and differ from the third objects ,
• Each paddle wheel 08 preferably has fewer than five blades 09, in particular fewer than three blades 09.
• the flat objects are transported by means of the conveyor line 03 and paddle wheels 08.
• the objects are transported one after the other along the conveyor line 03.
• One of these objects is removed from the conveyor line 03 and transported into a compartment 11 of a first paddle wheel 08.
• the remaining objects are transported along the conveyor line 03 to a second blade wheel 08 arranged behind the first paddle wheel 08 in relation to the transport direction of the conveyor line 03, and one of these objects is removed from the conveyor line 03 and transported into a compartment 11 of the second paddle wheel 08.
• the remaining objects are then transported along the conveyor line 03 to a third blade wheel 08 arranged behind the second paddle wheel 08 in relation to the transport direction of the conveyor line 03, and one of these objects is removed from the conveyor line 03 and into a compartment 11 of the third Paddle wheel 08 transported.
• the remaining objects are transported along the conveyor line 03 to a fourth blade wheel 08 arranged behind the third paddle wheel 08 in relation to the transport direction of the conveyor line 03, and one of these objects is removed from the conveyor line 03 and transported into a compartment 11 of the fourth paddle wheel 08.
• N of the number can correspond to the different objects arranged one behind the other on the conveyor line 03.
