Definitions

  • the above invention relates to an improved stapler for stapling the pages of magazines.
  • the joined pages are arranged with a corresponding angular offset on a rotating cylinder in such a way that the back of the magazine to be produced is directed towards a device for forming and inserting staples.
  • This device consists of a number of arms arranged in the manner of a cross, which are provided in such a way that they always impinge on the pages of a magazine to be stitched together during their rotational movement in periodic intervals.
  • the spinning arms instruct At its outer ends, devices for forming a staple made of metal wire.
  • the wire is fed to the devices for forming the staple by means of specially provided feed devices, these feed devices being arranged in the upper part of the frame, which receives the device for forming the staple.
  • a stapling device of the type described is already known from the prior art and therefore requires no further, more detailed description.
  • the known device is suitable for producing different stapling staples in accordance with the dimensions of the magazine, but it does not allow a fault in the stapling process to be determined and an additionally provided stapling device to be actuated automatically, in order to always have sufficiently stapled magazines available.
  • the stapling units described in the previous publication are arranged in a rotationally fixed manner on the machine frame, which means that the entire printing press always has to be stopped to repair or maintain the stapling units.
  • this task with a Stapler for stapling the rarities of magazines arranged on a rotating cylinder, with first devices for feeding metal wire and for forming U-shaped staples and devices for inserting the staples into the pages of the magazines to be stapled, thereby solved by additional devices for feeding of the metal wire and additional devices for forming and inserting U-shaped staples into the pages of the magazines to be stapled, that the first and the additional devices for feeding the metal wire and for forming U-shaped staples are arranged on and around a horizontal shaft Shaft independently of one another from a working position to a rest position and vice versa are arranged such that sensors are provided which monitor the correct insertion of the staples by the first devices and, in the absence of a staple, an alarm signal deliver a control unit, and that the control unit, in the presence of a fault signal, actuates the wire feed devices of the additional, working position devices for forming and inserting a U-shaped clamp.
  • At least one third feeding device for the metal wire is provided, which, however, is not used when the external devices work properly.
  • the feeding of the metal wire is only activated in the case of the centrally arranged device if a fault in the laterally arranged feeding devices of the metal wire is found due to the lack of stitching. This ensures that the pages of the magazine are always perfectly stitched together with two staples even in the event of faults in the devices arranged on the side.
  • a cylinder 1 which is rotatably driven in the direction of the arrow (f), takes up the sides 2 in a known manner on its circumference in a uniform, angular displacement, which are to be stapled together with metal clips.
  • This device is known from the prior art.
  • a known device for forming the staples and for carrying out the stapling operation is associated with the cylinder 1 for receiving the pages 2 to be stapled together.
  • This device is identified as a whole by 3 and consists of laterally arranged stands 4 which receive a stapler 5 which consists of arms 6 which are arranged in a cross shape.
  • the device 5 rotates in the direction of the arrow (g) and the speed of the rotary movement is synchronized in such a way that when the cylinder 1 (which receives the pages to be stitched together) with the stapler 5, the pages 2 always face the end of one of the arms 6 meet.
  • Known stapling devices 7 are arranged at the ends of the arms 6.
  • the side machine stands 4 receive a horizontally arranged shaft 10 which serves as a holding device for devices 8 which can be pivoted from a working position into a rest position and vice versa.
  • the devices 8 serve to feed a metal wire (F) and to form the staples, which advantageously have a U-shaped shape.
  • Controllable pliers which are also state of the art belong and are part of the stapler 7, serve to form the staple and to transport the shaped staples into the stapling zone in which the pages 2 of the magazine are stapled together.
  • all the feed devices 8 of the metal wire F are in the working position, as shown by solid lines in FIG. 1 and, thanks to the shaft 10, which is received by the upper ends of the side stands 4 of the machine, it becomes possible by Loosen tensioning screws, not shown, to pivot each wire feed device 8 from a working position 8 into a rest position 8 'as desired.
  • the rest position of the devices is shown with broken lines, and in this rest position (8 ') e.g. Repair work or maintenance work on the devices 8, 8 'are carried out without the entire stapler or even the entire rotary printing machine having to be stopped.
  • sensors 11 or other suitable devices are arranged at the location where the staples 2 are usually located, which detect the presence or absence of the staples in the passing magazines 2. Proximity switches, optical sensors or similar means can be used for this.
  • FIG. 2 which schematically shows the device 3 in view with a view in the direction of the arrow II in FIG. 1, shows an example of the arrangement of the devices 8 for feeding the metal wire and the formation of the staples.
  • the external devices 8 are those devices which are usually in the working position, and these external devices 8 are fed in a known manner via rotatably driven feed rollers 12 of the metal wire (F).
  • the metal wire F fed to the external devices 8 via the feed rollers 12 is deformed in such a way that a U-shaped clamp is formed, after which the metal wire in cut in a known manner and the U-shaped metal clip thus formed is used in the subsequent stapling process for stapling pages 2 of the magazine.
  • the centrally arranged feed device 8 for feeding the metal wire and for forming the staple is also always in the working position, in the normal case when the external devices 8 are working properly, but is the centrally arranged device 8 or the centrally arranged one Devices 8 no metal wire F fed with the aid of the feed rollers 12. For this reason, no staple is made in these devices.
  • the centrally arranged feed device 8 is only driven if one of the external devices 8 is working irregularly or if there are disturbances which do not make it possible to insert a staple properly. This error is determined by the sensors 11 already mentioned.
  • Fig. 3 the control and control units for the devices 8 for feeding the metal wire and for forming the staple are shown schematically.
  • the sensors 11 constantly deliver corresponding control signals to a control and control unit 13, which is formed, for example, by a microprocessor 13 or the control card of a small data processing system.
  • the sensors 11 can also be designed in such a way that they only emit a control signal if a staple in the pages 2 is missing.
  • the processing unit 13 emits a signal 14 which immediately actuates the feed device (feed rollers 12) for feeding the metal wire F to the centrally arranged device 8. This device, as previously described, was not driven until a stapling error occurred.
  • the formation of a U-shaped staple also takes place in this device 8.
  • the centrally arranged device 8 is driven in that an electromagnetic clutch or a pneumatic clutch, which is arranged in the interior of the head 8 for feeding the metal wire, is actuated, as a result of which the feed rollers 12 are set in rotary motion.
  • a control lamp 15 lights up in an advantageous manner, which indicates exactly which of the feed devices 8 has faults.
  • the device 8 which has the fault, is pivoted into the rest position 8 'shown in FIG. 1 in order to be subjected to the necessary repair work, and is then pivoted back again into the original working position 8.
  • the control button 16 is actuated (reset).
  • the control device also has a switch 17, with which it is possible, according to choice and by hand, to interrupt the operation of one of the devices 8 arranged on the side by interrupting the feeding of the stitching wire.
  • the device 8 arranged in the center is actuated automatically, e.g. during the rest position of one of the laterally arranged devices 8 to carry out the simple and convenient replacement of the coil of the metal wire that is coming to an end.
  • feed rollers 12 for the metal wire F are provided over the pliers 9 of the rotating arms 6, which are part of the stapler 3.
  • This metal wire F is gripped, cut and deformed in the devices 8 by the pliers 9 to form a U-shaped clip (not shown), which clip is subsequently used for stapling the pages 2 of the script.
  • the feed rollers 12 for feeding the metal wire F are taken up by the corresponding device 8, a half 108 of this device can be pivoted about an upper axis 10 will. With the aid of two shafts 18 and 19, each device 8 receives known feed rollers 12 for the feed of the metal wire F.
  • the shaft 19 is operatively connected to an adjusting device 20, which, however, is not part of the above invention.
  • the shaft 18 has at its upper end a gear 21 which is operatively connected to a toothing 22 of the shaft 19. Furthermore, the drive shaft 18 is operatively connected to a conical gear 23, which meshes with a second conical gear 24, which is operatively connected to a horizontally arranged shaft 25.
  • the end of the shaft 25, which is part of the fixed part of the device 8, has a spur toothing 27 which can be connected by means of a form fit to a counter toothing 28 which is part of the horizontally arranged shaft 29 in the pivotable part of the feed head 108.
  • the shaft 29 is firmly connected to one half 30, an electromagnetic clutch 31.
  • the second half 32 of the coupling is operatively connected to a sleeve 33 which is rotatably mounted in the housing of the device 8 via a ball bearing 34 and is mounted on the shaft 29 with a further ball bearing 35.
  • the sleeve 33 which is rotatably mounted, has a toothing 36 with which a threaded spindle 37 is operatively connected, which traverses all the fixed parts of the devices 8 in order to impart a rotary movement to the corresponding sleeves.
  • the threaded spindle 37 is advantageously driven by an electric motor (not shown), or else the rotary movement is derived from a rotating component of the stapler.
  • the sleeve 33 rotates idle on the bearings 34 and 35, and no rotation is transmitted through the shafts 29-25 to the feed rollers 12 to feed the wire F.
  • the electromagnetic clutch 31 is actuated, e.g. is excited by control signals of the microprocessor or is switched off, the shaft 29, 25 is set in rotation, and this rotation is synchronized via the pair of conical gears 23, 24 and the gears 21, 22 to the shafts 18, 19 and thus to the Transfer feed rollers 12, whereby a supply of the wire F is made possible, thereby the supplied wire is gripped by the pliers of the device 6 and the U-shaped staple for the subsequent stapling process is generated.
