Definitions

  • the invention relates to a saddle stitcher with a fastening element formed along at least one strand of an endlessly rotating chain-like traction device with supporting elements forming a saddle-shaped support for the printed sheets spread apart one after the other, and with catches which are arranged in a subsequent section for stapling the printed sheets placed one above the other Stitching section opens.
  • the printed sheets to be processed after leaving the feeder, pass through a collecting section on which the printed sheets are spread apart and a stitching section adjoining the collecting section, on which the complete printed products are left collected printed sheets are usually stapled twice on the fold length.
  • the printed sheets are moved into the loading position of the next feeder by the carriers provided on at least one traction means.
  • a roller chain is used for this purpose, the chain links after each of which form an uninterrupted chain saddle-shaped support are provided with sloping support surfaces on both sides of the roller chain, the upper edge of the support being located approximately above the longitudinal central axis of the roller chain.
  • the collecting section or the conveyor chain assigned to it ends due to the embodiment of the support just described, which prevents the bending device driven from the bottom up in the longitudinal center axis of the roller chain or the upper run of the traction mechanism from being delivered.
  • the complete printed products are transported to the stitching section by a conveyor device suitable for carrying out the stitching process, e.g. two parallel traction drives as a continuation of the support of the collecting section or so-called finger strips, which move the printed products into the intended stitching position , recorded in order to be able to transport the stapling and then the printed products.
  • a conveyor device suitable for carrying out the stitching process e.g. two parallel traction drives as a continuation of the support of the collecting section or so-called finger strips, which move the printed products into the intended stitching position , recorded in order to be able to transport the stapling and then the printed products.
  • the resources required for this are associated with great effort.
  • the object of the invention is to provide a saddle stitcher - also a drum saddle stitcher with a plurality of saddle and stitching sections - of the type mentioned at the beginning, which allows a simpler embodiment with reliable processing of the printed sheets.
  • this object is achieved in that the saddle-shaped support extending over the collecting section and stitching section is formed, at least on a partial section, by supporting elements lined up one above the other with a support surface that slopes away at one side.
  • the proposed solution permits a simpler and lighter design of the conveying elements directly affected and interacting by the collecting and stapling process and an optional design of the collecting and stapling section.
  • the construction according to the invention proves to be particularly advantageous if the saddle-shaped support on the collecting section is formed from two parallel runs of two endlessly rotating traction means, which reliably ensure the transport of the printed sheets also in the area of the stitching section.
  • the designer reserves the right to determine whether the traction means should have different lengths in order to be able to maintain both the stitching process and the continuous processing cycle or conveying cycle.
  • the collecting section and the stitching section are formed by a common run of a traction means and in this way secure the collecting process, the conveying and the stapling of the printed sheets.
  • a traction means formed with a shorter strand is preferably assigned to the collecting section without impairing the stapling process in that the traction means of the shorter strand ends before the stitching section.
  • One of the traction means forming the support can expediently end in front of the stitching section, for example the traction means with a shorter strand, the resulting one-sided gap or the interruption of the support being remedied by a stationary guide element which interacts with the supporting elements attached to the adjacent traction means.
  • a guiding element which rises approximately in the longitudinal central axis of the support up to approximately its upper edge can subsequently be arranged at the conveying end of the shorter traction means.
  • the traction means are advantageously designed as link chains, which prove to be a simple drive element.
  • the device according to the invention enables a favorable arrangement of the bending device to be lifted from below onto the upper side of the support or of the stationary guide element assigned to the transition point between the end of the shorter traction means after the collecting section and the stitching section, in that the support at the upper end forms one of the ending contact surfaces of the support elements of two Traction means or the stationary guide member separating passage opening for the delivered bending device, which is arranged approximately in the longitudinal center plane of the support in a guide housing and / or has the guide element assigned to the transition point.
  • the lateral support surfaces of the support formed by the support elements expediently extend over the traction means or. Link chains down to cover them.
  • the support elements can be designed according to various embodiments and can be connected to the traction means.
  • the link plates of the chain links can be formed in one piece in such a way that they are connected to the laterally sloping bearing surface of one support element or to another Embodiment have an additional supporting, approximately perpendicular support web.
  • Sheet steel which has the necessary strength for the chain links, is suitable as a material.
  • a supporting element has proven to be advantageous, which is designed to be attachable to the articulated chain by means of a spring clip lock, plastic or steel sheet being suitable for this purpose.
  • the bolts projecting laterally beyond the connecting straps of a link of the link chain are provided so that they can receive a yoke-shaped adapter connected to the support element in a non-positive and / or positive manner.
  • the yoke-shaped adapter has lateral clamping strips which have latching grooves or the like on the inside facing the chain links.
  • the support surfaces of the support elements protrude beyond the division of the articulated chain and in this way prevent the formation of gaps.
  • the width of the support elements is asymmetrical with respect to the conveying direction and extends over more than one chain pitch, they can be used as ejectors in the deflection areas of two parallel strands.
  • the distance between the carriers can be changed so that economical processing can be achieved which is adapted to the formats of the printed sheets.
  • the ridge bar, the bending device and / or the guide element can be arranged between the support elements or the stationary guide element in a simple manner.
  • FIGS. 1 and 2 show sections of a support 1 which can be fed by a saddle stitcher (not shown), for example on the collecting section, which is formed by an upper run of an endlessly driven traction means 2 - here an articulated chain with supporting elements 3 attached to it.
  • a saddle stitcher (not shown), for example on the collecting section, which is formed by an upper run of an endlessly driven traction means 2 - here an articulated chain with supporting elements 3 attached to it.
  • Driver 4 fastened to the traction means 2 follow one after the other, which are guided past the feeders and take over or convey the spread sheet which is spread out in each case.
  • the drivers 4 are each arranged between two subsequent support elements 3, for which purpose, for example, a chain section of two chain links is required.
  • the catches 4 can be mounted on the traction means 2, preferably on the chain locks, on one side so as to be pivotable about an axis arranged at right angles to the conveying direction, so that they can be lowered against the conveying direction after passing through the stitching path, as shown in FIG. 2 .
  • FIG. 1 shows a possible cross-sectional shape of a support element 3 fastened to a link chain 2 designed as a traction means.
  • the support elements 3 have a support surface 5 which slopes down obliquely on one side above the traction means 2, each of which is part of the longitudinal and central plane 6 of the collecting and stitching section form evenly distributed saddle-shaped support 1.
  • a further support element 3 can be seen in FIG. 1, in addition to the other support element 3, representing a saddle-shaped support 1.
  • the traction means 2 required for this have the same speed and are also driven in the processing cycle.
  • the upper run of the articulated chain 2 lies on a longitudinal guide 7 which is connected to the machine frame 8.
  • a bow-like rail 9 is provided, which extends over an adapter 10 connected to the support element 3 along the articulated chain 2, whereas the opposite lower run of the articulated chain 2 is provided by an opposite, similar bow rail (not visible) is guided against sagging.
  • the rail 9 is in turn screwed to the machine frame.
  • Reference numeral 16 indicates a ridge ledge forming the ridge-like upper edge of the support 1, which may accommodate the bending device 11, which can be raised - as shown - and lowered again into the rest position during the stitching process on the stitching path.
  • a stationary guide element 12 is connected at a short distance, which is aligned with the support surfaces 5 of the support elements 3 on one side of the longitudinal center plane 6 to form a complete support of the printed sheets.
  • a guide element 13 which interacts with the stationary guide member 12 and is located approximately in the longitudinal center plane 6, is provided, which has a guide section which rises steadily as viewed in the conveying direction of the printed sheets and which, when the top edge of the support 1 reaches a parallel to the latter Section merges.
  • the contact surfaces 5 of the support elements 3 reach with their lower edge approximately the height of the longitudinal guide 7 of the articulated chain 2 for their protection against external influences.
  • the support elements 3, here made of plastic, have an adapter 10 connected to the support surface 5 as a fastening element with the articulated chain 2.
  • This adapter 10 is yoke-shaped in cross-section, so that it can be used as a spring clamp on the articulated chain 2, so that it can be plugged on and removed.
  • the ends of the bolts 15 projecting laterally over the connecting straps 14 of the articulated chain 2 serve as a pin-like device on which the adapter 10 or a support element, provided with latching grooves or bores, is held.
  • the removal or Replacing a support element 3 on the traction device is done by deformation or by lifting the lateral terminal strips of the adapter.
  • the bristles 17 or retaining springs protruding from the upper ends of the support elements 3 reduce the sliding ability of the printed sheets on the support when the traction mechanism transmission stops.
