Definitions

  • the invention relates to a device for loading the collecting section of a saddle stitcher according to the preamble of claim 1.
  • feeders Devices of the type mentioned at the beginning, also called feeders, are the Achilles tendon when loading the collecting section of a saddle stitcher with printed sheets of different paper quality and thickness.
  • the printing sheet guide before the stop for the fold of a printing sheet pulled from a stack often leads to misfeeds which result in a defective printed product being discharged at the end of the collecting or stapling process.
  • this deficiency is due to an imprecise adjustment of the printed sheet guide or the guide arrangement before the stop, where the printed sheet is exposed to an impact and compression effect.
  • The tends to The printed sheet is at least partially lifted off the conveyor drum and experiences a position in the guide gap such that it cannot always be detected in the correct position by the opening device which then acts on the opposite edges of the open sides.
  • the production reliability could be improved by more precisely adapting the guide gap to the different printed sheets.
  • the object of the invention is now to provide a device of the type described in the introduction with which the reliability with regard to processing quality can be improved and the production time can be shortened.
  • this object is achieved according to the characterizing part of patent claim 1, whereby the situation of the guide arrangement on the conveyor drum, above the horizontal plane running through the axis of rotation of the latter, can be used to promote the sliding effect in the guide gap, in particular because the statically acting one Gravity on the guide assembly can be reduced considerably.
  • the resulting favorable friction conditions also result in a gentle treatment of the printed sheets.
  • the adjustment of the guide arrangement advantageously takes place against a force which is generated by gravitation and / or a spring.
  • This force should preferably also be adjustable.
  • the one upstream of the stop device approximately perpendicular to the trajectory of the printed sheets or the conveying drum in the guide gap Movable guide roller and a guide element adjoining the latter, which can be actuated independently of the guide roller, form the guide arrangement, the rotatable guide roller being expediently mounted on a support which forms the access opening to the stop with the lower edge, so that the printed sheet striking the stop does not deviate from its position or does not that the printed sheets are in a constant detection position with respect to the downstream opening device.
  • a support is particularly suitable as a lever, on the free end of which the guide roller is mounted, wherein instead of a pivot axis for the lever, the support could be moved in a guide for the same purpose.
  • the support or the lever is attached to the stop device.
  • an end stop is assigned to the support or lever.
  • the guide member is advantageously connected to a guide device and is guided such that it can be lifted off from the latter, approximately radially to the axis of rotation of the conveyor drum, so that approximately uniform friction conditions occur in the guide gap on the printing sheet surfaces concerned.
  • the guide device is preferably designed with a roller guide which has a relatively favorable coefficient of friction.
  • the guide device connected to the latter makes an angle of less than 45 ° with a horizontal plane through the axis of rotation of the conveyor drum.
  • the single figure shows a guide arrangement 1 on the conveyor drum 2 of a printing sheet feeder 3 for a saddle stitcher (not shown), as is disclosed for example in the Swiss patent specifications 586 611, 617 905 and 652 103.
  • This feeder 3 is used to load a collecting section of a saddle stitcher and consists of a rotating conveyor drum 2, which pulls the printing sheets folded in advance from a stack 5 of an adjacent sheet magazine 6, of which the table 7 is shown in the figure, which one part of the individual printing sheets 4 from the underside of the stack lifting device and a gripping device (both not shown) which detects the lifted sheet parts are assigned, and a stop device 8 which is arranged on the orbit of the sheet 4 and which stops the fold, which cooperates with an upstream guide arrangement 9, which forms a guide gap 10 with the conveyor drum 2.
  • This guide arrangement 1 also acts on the printed sheets 4 when they are picked up by the opening device (not shown) and transported in the opposite direction to the collecting section.
  • the printed sheets 4 fed to the stop or the stop device 8 lift the guide arrangement 9 off the conveyor drum 2, this taking place against a force formed on the guide arrangement 9 from gravitation and / or against a spring force.
  • the stationary stop device 8 is preceded by a guide roller 10, which is freely rotatably mounted on a lever 12 and is set in rotation by the printed sheet 4 in the guide gap 10. In the rest position, the guide roller 11 is in contact with the conveyor drum 2 by a compression spring 13 acting on the lever 12.
  • the stop device 8 has an access opening 14 leading to the stop, which is designed to be adjustable on the one hand by a bottom guide surface which is curved from below to a lower guide surface aligned with the conveying drum 2 and on the other hand by the lower edge of the lever 12.
  • the stop itself is constructed by a stop element 15 made of rubber or a rubber alloy that dampens the impact of the printed sheets 4.
  • a recess 16 on the lever 12 is provided with a cam 17 which is assigned to an end stop 18 on the stop device 8.
  • the guide arrangement 1 has a guide element 19 which, with the exception of the end section 20 facing away from the stop, runs approximately parallel to the circumference of the conveyor drum 2 along the length of the guide gap 10.
  • the lower edge of the lever 12 forms a section of the guide gap 10 between the stop and the guide roller 11, the guide roller 11 being adjustable, for example by means of a, for adjusting the passage width of the section mentioned eccentrically rotatable shaft on which lever 12 is mounted.
  • the guide member 19 is in turn connected to a guide device 21 and guided by this approximately radially liftable from the conveyor drum 2, the printed sheets 4 producing the guide gap 10 having a thickness of up to approximately 2 mm. It is necessary that the end section 20 of the guide member 19 opposite the stop on the guide gap 10 is formed with an approximately tangential course against the conveyor drum 2 with an expansion of the guide gap 10.
  • the guide device 21 shown as a roller guide has a roller conveyor 22 fastened to the underside of the table 7 of the sheet magazine 6, in which rollers 23 connected to the guide element 19 are arranged.
  • a slot 24 running parallel to the roller conveyor 22 forms the maximum lifting distance of the guide member 19 from the conveyor drum 2 for a stop pin 25 connected to the guide member 19, whereby the guide member 19 is lifted off the conveyor drum 2 by more than the thickness of the printed sheets 4 the removal of the printed sheets 4 in the event of a fault.
  • the rollers 23 could conversely also be connected to the stationary table 7 and the roller guide 22 to the guide member 19. The direction of movement of the guide arrangement 1 or with the latter, respectively.
  • the guide device 21 connected to the guide member 19 forms an angle of approximately 30 °, but a maximum of 45 °, with a horizontal plane running through the axis of rotation of the conveyor drum 2.
