Definitions

  • the invention relates to a boom for the removal of folded printed products, which are transported astride a saddle-shaped support of a transport device by rotating drivers, with a gripping device having at least two rotating gripping members, between which the printed products are taken and discharged from the transport device.
  • Booms of the type mentioned are known in the printing industry for a long time and are used in particular for the most gentle lifting of printed products, such as brochures, newspapers and the like from a longitudinal collection line.
  • the lifted from the hunt group printed products are deflected and fed, for example, a cutting device for head, foot and front trimming.
  • the collection route has in particular an endless collecting chain on which are thrown off to form the printed products with investors from a pile sheet.
  • drivers are arranged at regular intervals, with which the discarded and folded sheets are transported.
  • the drivers can be adjustably attached to the gathering chain for a pitch change.
  • selective binding the printed products are selectively assembled.
  • the printed products can in this case change in particular with respect to their thicknesses.
  • the printed products formed are usually bound, stapled in particular in the field of collecting chain by means of a stapler.
  • the gathering chain is preferably a double-collection chain.
  • the production speed is often limited by the performance of the boom, which must gently and simultaneously lift and redirect the printed products trouble-free.
  • the printed products must each be lifted off the transport path at high speed, so that the trailing printed product does not collide with the leading printed product.
  • the grasping and lifting of the printed products must also be so gentle that the printed products are not damaged and, in particular, no marks are produced on the outside.
  • selective binding printed products of different thicknesses and different formats should also be able to be removed with such high performance.
  • CH-A-358 100 discloses a cantilever in which the printed products are lifted with a sword and pushed in between pairs of rollers arranged one behind the other.
  • the axes of rotation of the pairs of rollers are parallel to the plane of motion of the sword and ever directed perpendicular to its oblique components of movement.
  • the oblique orientation of the movement of the sword and the roller pairs and a drive connection of the sword are dimensioned so that the printed products maintain their horizontal conveying speed when lifting.
  • the deflection of the printed products is comparatively abrupt and not particularly gentle on the product.
  • the production speed of this machine is limited to 8,000 to 10,000 copies per hour.
  • a disadvantage of this device is the comparatively large space requirement for the rotating gripping members and the necessary large gripper forces to control occurring during the deflection of the printed products acceleration and deceleration forces, difficulties may also occur in the processing of individual sheets that may occur in a malfunction.
  • the gripping members must be able to be changed over in the course automatically to the thickness of such a single arc, which is structurally relatively expensive. With a pitch change from 21 "to 14", the number of gripper arms must also be increased from two to three.
  • the invention has for its object to provide a boom of the type mentioned, which allows an even higher production speed and yet works gently and reliable. He should also be compact executable.
  • the gripping device has at least two oppositely rotating, paired carrier, wherein on the circumference of each carrier each one of the two rotating gripping members is mounted.
  • the printed products are caught by rotating gripping members, which are each mounted on a rotating carrier.
  • the movement of the printed products is thus not limited to a circular path or a linear path, but can be optimally designed become.
  • the web can be determined so that the above-mentioned collision with the trailing printed product is avoided at higher production speeds. It is a speed course possible in which the printed products practical shock-free and thus very gentle on the product taken by the gripping members and transferred with a very small impact to another transport device, such as tapes. Rotating arms are not required and a particularly compact design is possible.
  • the gripping members are of a beehive-shaped design.
  • the largest diameter of the beehive-shaped gripping members is preferably designed so that the resulting peripheral speed per cycle is greater than the chain pitch of the transport device. Due to the slightly larger horizontal maximum peripheral speed of the hive-shaped gripping members relative to the speed of the transport device, the printed product can be optimally pulled away from the carriers.
  • the beehive-shaped grippers are preferably arranged so that the printed products move when rotating the carrier in the direction of decreasing diameter. The printed products are thereby continuously decelerated in the horizontal direction and transferred with minimum horizontal speed to the perpendicular thereto arranged further transport device.
  • the boom 1 is arranged in the region of a transport device 8, which according to FIG. 1 conveys printed products 5 by means of a double collection chain 2 in the direction of the arrow 6.
  • the double collection chain 2 is formed according to FIG. 3 from two single chains 3 and 4 and has a saddle-shaped support 43, on which the printed products 5 are conveyed astride.
  • the printed products 5 are taken with laterally projecting dogs 7.
  • the driver 7 can be preferably adjusted to change the chain pitch.
  • the printed products 5 are usually made of several sheets that are dropped with investors not shown here on the double collection chain 2.
  • the folded printed sheets, by which the printed products 5 are formed, can be opened in these investors and stored on the gathering chain 2.
  • the printed products 5 therefore each have a fold 5a, which extends during transport on the double collection chain 2 in the transport direction.
  • the saddle-shaped pad 43 the printed products 5 are transported spread at an acute angle.
  • the printed products 5 can also be single folded sheets.
  • a Abhebeatt 34 is provided, which is arranged according to FIG. 3 between the two gathering chains 3 and 4 and having an upper comb-like edge 44, as shown in FIG.
  • the lift-off blade 34 is connected to and driven by two crank pulleys 35 so that it executes a closed circular or oval cam track in a vertical plane and lifts a printed product 5 from the double-pickup chain 2 with each handling and lifts it into the detection range of the boom 1.
  • the two crank disks 35 are rotatably mounted on two axles 37, one of these axles being a drive axle and the two crank disks 35 each being connected to each other by an endless toothed belt or chain 36.
  • the boom 1 has two bearing plates 9 and 10, at the distance from each other two mutually parallel drive shafts 14 are stored.
  • the shafts 14 are each rotatably connected to a drive wheel 11, around which an endless toothed belt 12 is placed.
  • On each drive shaft 14 are rotatably mounted three spaced apart disc-shaped support 15 is fixed, which are arranged in pairs, as seen in pairs. It is also conceivable embodiment with less than three or more than three carriers 5 per shaft 14.
  • the carrier 15 are driven so that they rotate in FIG. 4 in the counterclockwise direction. In Fig. 4, the left carrier 15 are driven according to arrow 55 in the counterclockwise direction and the carrier 15 shown on the right in accordance with arrow 56 in the clockwise direction.
  • the rotational speeds and the peripheral speeds of the carrier 15 are the same.
  • each support 15 two beehive-shaped rollers are mounted, which, as can be seen, are arranged diametrically with respect to the corresponding drive axle 14 and form the gripping members 20.
  • the rollers or gripping members 20 are each mounted on an axle 24, which is fastened with a holder 25 on the carrier 15.
  • the carriers 15 are, as can be seen, each provided with a bearing 23 which receives an axle 24.
  • the axles 24 each extend transversely to the drive axles 14.
  • the rollers or gripping members 20 are each driven by a bevel gear 42 having a non-rotatably connected to the axis 24 wheel 27, which meshes with a wheel 17 which is mounted on a drive shaft 16.
  • Each drive shaft 16 is rotatably mounted according to FIG. 2 on two discs 46 and 47, each fixed to one of the drive shafts 14th are connected.
  • a spur gear 18 (sun gear) is fixed, run on the two diametrically opposite planet gears 19 which are fixedly connected to one of the drive shafts 16.
  • Each roller 20 or each gripping member is arranged according to FIG. 4 in each case in an approximately V-shaped, outwardly open gap 51 and has a cambered lateral surface 40, which forms a circular contour with a lateral surface 26 of the carrier 15. Both the rollers or gripping members 20 and the carriers 15 are provided on the lateral surfaces 26 and 40 with a rubber-elastic coating 28 and 21, as can be seen in particular Fig. 3.
  • the belts 31 and 30 form two transport devices 52 and 53.
  • a switch 33 is arranged between them and selectively supplies the printed products 5 to the transport device 52 or 53.
  • the printed products 5 are fed to the transport device 53.
  • the adjustment of the switch 33 is effected by control means, not shown here.
  • the transport devices 52 and 53 cause a deflection of the printed products 5 in a substantially horizontal plane.

  • each a printed product 5 is detected and raised on the inside of the fold 5a.
  • Figs. 1 and 3 show a printed product 5 ', which is detected by the lift-off blade 34 and raised.
  • the lift-off sword 34 will now immerse again on its further path between the two chains 3 and 4 and capture a subsequent printed product 5 and lift it in the same way.
  • the raised printed product 5 ' is detected in the region of the fold 5a' by pairs of rollers or gripping members 20.
  • the lift-off blade 34 is, as mentioned above, corresponding to the rollers or gripping members 20 comb-shaped, so that the lift-off blade 34 is not detected by the rollers or gripping members 20. Due to the rotation of the carrier 15, the detected printed product 5 'is accelerated vertically upward. At the same time takes place by the rotation of the rollers or gripping members 20 has a horizontal acceleration in the transport direction of the double collection chain 12 and thus in the direction of arrow 6. This horizontal acceleration has the highest value in the arrangement according to FIG. 3, since in the detection range of the rollers or gripping members 20, the diameter D of these rollers 20 largest is.
