Definitions

  • the invention relates to a device for feeding a processing line with printed products.
  • a device in which partial products are taken over to receiving stations and transferred to the processing line by means of clock chains.
  • the advantage here is that the clock chains in the transfer area run in the same direction with the processing line and so the products along can pass.
  • a disadvantage is the considerable mechanical complexity associated with corresponding manufacturing costs and the failure-prone repeated transfer of the partial products.
  • the large footprint of the entire supply and the delivery point on the processing line is disadvantageous.
  • the processing line comprises segments in the form of pockets arranged one behind the other.
  • Each bag has rollers at an upper end, with which the lowest printed product is removed from a stack and fed to the bag.
  • CH 684 589 A a method and an apparatus for separating stacked printed sheet has become known, after which the sheets are respectively detected at the front end of a stack of drivers and transported rolling to a remote from the stack delivery point for further processing, wherein the signature on the way to the delivery point a sticky supplement is supplied.
  • the prior art CH 408 970 A provides a saddle stitcher feeder having a rotating drum circumferentially provided with a plurality of processing cells for turning the printed products through one revolution so that it can be placed astride the saddle-shaped processing line after opening.
  • EP 0 405 107 A1 describes a device for separating stacked paper sheets, which are fed by a rotary feeder to a conveying device.
  • the invention has for its object to provide a device of the type mentioned, which avoids the disadvantages mentioned above and is still reliable.
  • the device is intended to enable a faster transport of printed products and in particular printed products or supplements, for example in pocket chains or insertion machines.
  • the object is achieved in a generic device according to the features of claim 1.
  • the printed products are separated with the processing cells of an investor.
  • the separated printed products are delivered consecutively over several processing cycles to the segments of the processing section. As a result, there is more time available for the individual sub-process and it is possible for several printed products to be out of phase with one another.
  • the feeder is a peel-off feeder.
  • the printed products are removed from the stack or magazine with suckers.
  • suckers are vented, for example via a slide valve.
  • the feeder has belts which cooperate with the processing cells for holding the printed products.
  • the printed products which are preferably taken on a wheel with suckers, are guided with revolving belts.
  • the device according to the invention makes it possible to deposit the printed products in the segments of the processing line with a leading fold.
  • an embodiment in which the printed products are deposited with an open side in front, in particular placed on a saddle-shaped segment of the processing path, is also conceivable.
  • the apparatus 1 shown in FIG. 1 consists essentially of a magazine or stack 2, a feeder 3 and a processing section 4. As can be seen, the feeder 3 is arranged above the processing line and below the stack 2. With the feeder 3, printed products 5 are withdrawn from the stack 2 and fed to the processing line 4, which feeds these printed products 5 to a further processing device, not shown here, in the direction of the arrows 18.
  • the printed products 5 are for example folded sheets or inserts. In particular, these products are partial products.
  • the stack 2 has a bottom open frame 32, in which the printed products or partial products 5 are stacked one above the other. If these printed products 5 are provided with a fold 5a, this is shown in FIG. 1 on the right as shown, while the open side 5b is on the left.
  • the printed products 5 can also be sheets without fold.
  • the feeder 3 is a peel-off feeder and is essentially a drum 10 which is mounted on a drive shaft 6 and rotates in the direction of the arrow 14.
  • a plurality of processing cells 7 are arranged at uniform intervals, which are each rotated about a shaft 11 in synchronism with the rotational movement of the drum 10.
  • the rotation of the processing cells 7 takes place according to the arrows 12 and by a drive.
  • the peripheral surfaces 13 of the drum 10 thus move the lateral surfaces 7a of the processing cells 7 in the opposite direction to the rotational movement of the drum 10.
  • the opposite speeds are preferably about the same size, such that the tangential velocity of the processing cells is preferably zero at its periphery.
  • the processing cells 7 each have a plurality of suction cups 19 each having a peripheral suction opening 21.
  • the suckers 19 are connected via an axially extending channel 20 and via a valve plate to a vacuum line leading to a vacuum source, for example a vacuum pump.
  • a frame-fixed valve plate has a kidney-shaped recess 28, which determines the angular range in which the suckers 19 are effective.
  • the nipple 19 is the twelve o'clock processing cell 7 'evacuated.
  • the diametrically opposed processing cell 7 "is ventilated.
  • the suckers 19 serve to peel off the stack 2 in each case the lowest printed product 5 '.
  • the evacuation of the suckers 19 takes place in such a way that the printed product 5 'to be peeled off is grasped on each side in the vicinity of the fold 5a.
  • the arrangement of the printed product magazine in the upper drum half is expedient.
  • a guide plate 15 is in this area or a similar guide means provided which is adjustably mounted on a bracket 16.
  • the processing cells 7 are reversed 360 ° rotated about its shaft 11.
  • the teat 19 are vented and in the further movement, the captured printed product 5 '' is still guided by the bands 8.
  • the fold 5a projects beyond the circumference 13 of the drum 10. The fold 5a now moves according to FIG. 1 on a line which is inclined relative to the transport direction 18.
  • the pockets 17 of the processing line 4 are positioned so that the printed product 5 '''down into a pocket 17' protrudes and is released on further transport into this. It is essential that in this process, the printed product 5 '''along with the processing line 4 in the same direction, in the direction of arrow 18. During the transfer, the printed product 5 '"does not have to be accelerated. It is also essential that the printed product 5 '"is guided through the processing cell 7" and the belts 8 until it is completely transferred to the pocket 17'. In the dot-dashed position shown in FIG. 1, the printed product 5 has left the feeder 3. Since, as mentioned, an uncontrolled state is avoided, a comparatively high transport speed can be achieved.
  • the pockets 17 can be loaded with other investors 3 not shown here.
  • a device 1 with a plurality of investors 3 arranged one behind the other is conceivable, each supplying print products of the processing section 4 from a stack 2.
  • a bag 17 thus successively printed product can be stored.
  • FIG. 3 shows a device 1 in which a processing path 4 'running convexly beneath the feeder 3 is arranged.
  • a processing path 4 'running convexly beneath the feeder 3 is arranged.
  • FIG. 3 shows a device 1 in which a processing path 4 'running convexly beneath the feeder 3 is arranged.
  • a convex course is For example, it is possible to open the pockets 17 for loading the printed products 5.
  • the bag 17 'relative to the pocket 17 as shown against the top further open.
  • the processing section 4 "shown in FIG. 4 has saddle-shaped supports 29 on which the printed product 5 is placed in such a way that the fold 5a is at the top, as can be seen.
  • the printed products 5 are placed so that the open side 5b precedes.
  • the processing cell 7 is controlled approximately after reaching the eight o'clock position so that its direction of rotation is reversed.
  • the processing cell 7 rotates according to arrow 35.
  • the printed product 5 is moved so that the open side 5b projects downwards.
  • the printed product is opened on its lower side 5b such that the printed product is placed astride the saddle-shaped support 29 as shown in FIG becomes.
  • This processing section 4 '' can be rectilinear, according to Figure 3 convex or concave.
