Definitions

  • the perforation punching is effected by rotary punching tools secured to driving shafts and including a first tool provided with readjustable punch pins mounted in a receiving body and a cooperating second tool provided with punch dies.
  • the punch pins are regrindable by a grinding attachment, to tangency of their working ends with a common circle concentric with the axis of rotation of the first tool.
  • the grinding attachment is mounted adjustably on the machine frame and permits regrinding the pins without removing the tool from its working position.
  • the pin resetting device is mounted in the receiving body coaxial with the driving shaft of the first tool and acts simultaneously on all of the pins.
  • the resetting device is actuable, for rotation, by an actuating means which is externally accessible.
  • the pins are of equal length and have oblique inner ends which are resiliently biased against a conical ring which can be moved axially by a gear wheel threadedly engaged with the receiving body and rotated by a pinion which, in turn, has an externally accessible drive shaft.
  • the pins are of equal length and have oblique inner ends which are resiliently biased against a conical ring which can be moved axially by a gear wheel threadedly engaged with the receiving body and rotated by a pinion which, in turn, has an externally accessible drive shaft.
  • the pins are of equal length and have oblique inner ends which are resiliently biased against a conical ring which can be moved axially by a gear wheel threadedly engaged with the receiving body and rotated
  • This invention relates to rotary printing presses having devices for punching rows of perforations in continous webs, the devices being in the form of rotary punching tools secured to driving shafts and including a first tool provided with readjustable punch pins mounted in a receiving body and a second tool provided with punch dies, and, more particularly, to such a rotary printing press in which all the pins may be radially adjusted simultaneously and may be re-ground so that their outer ends are tangent to a common circle concentric with the axis of rotation of the first tool, by means of a grinding attachment adjustably mounted on the machine frame.
  • rotary perforation punching tools used in rotary printing presses, are of the type in which each individual pin of an upper tool is clamped in a respective bore of the receiving body by a screw, from the front side. After a certain service time, the pins are worn down to the extent that it is no longer possible to obtain uniform perforations. To reset the tool, it has been necessary individually to release each pin, readjust its protruding length, and to clamp the pin in position again. This work still occurs outside the rotary press. Thus, for resetting, the upper tool must be removed from the shaft and, at a suitable working place, each pin must be reset to obtain a length as accurate as possible and to be reground on a separate machine.
  • the present invention is directed to the problem of press and which furthermore is capable of displacing the pins radially by equal distances, and by mounting the grinding device on a cross beam of the frame of the rotary press, the cup wheel of the grinding device being adjustable to the reset pins of the upper tool while the latter remains in its working position.
  • the invention makes it possible to reset all of the pins of a punching tool simultaneously by the same distance without removing the tool from the rotary press, and thereafter immediately to regrind the reset pins to accurate tangency of their outer or working ends with a common circle concentric with the axis of rotation of the tool.
  • Both the resetting operation and the regrinding operation may be performed in a very brief period of time and, for the grinding, there may be utilized the driving mechanism already provided in the press for the punching tools, so as merely to run the machine at a lower speed and without the paper web therein.
  • the accuracy of the grinding is improved because the upper tool to be reground remains on its shaft in its working position.
  • the grinding cup wheel is driven separately, and need only be adjusted to the exact diameter of the punching tool,.that is, to the exact diameter of the common circle concentric with the axis of rotation of the tool. A reciprocating movement of the grinding cup wheel during grinding is not necessary, because the cup does not produce tooling marks.
  • grits and ground way material are evacuated through an auxiliary nozzle connected to a suction or exhaust device which is already provided on the rotary press for removing the perforation waste.
  • the receiving body mounted in the receiving body of the upper tool, the receiving body comprises a hub having an external thread, and a gear having a corresponding intemal thread is screwed on to the external thread, the gear being provided with a hub bearing a conical ring, which is fixed against axial displacement relative to the gear, and which has a conical surface against which rests the inner ends of pins having equal lengths.
  • the inner ends of the pins are provided with corresponding oblique surfaces and subjected to the bias of compression springs.
  • the gear meshes with an axially fixed rotatable adjusting pinion mounted in the receiving body, and secured to a shaft which constitutes an externally accessible actuating means.
  • the pins are always equal in length and remain in the tool until all the pins are entirely used up.
  • the maximum resetting is effected by biasing the inner ends of the pins against the conical surface in the zone of its maximum diameter.
  • the adjustment resetting path of the conical ring is limited by a stop screw cooperating with the gear and secured by a lock nut.
  • the gear is moved in the opposite direction, all of the pins are retracted uniformly into the receiving body, under the spring bias.
  • the resetting device permits putting an upper tool,'equipped with perforation pins, out of operation, so that it will not perform any perforating operation. In this case, also, the resetting device makes it unnecessary to remove a punching tool from its shaft when it is not to be used.
  • the receiving body has associated therewith a disc having a spiral external periphery with a regular gradient, and which is mounted on the hub of a covering flange and provided with another hub in the form of a gear.
  • Pins of gradually different lengths and overall cylindrical shape are biased against the spiral peripheral surface of the disc.
  • the uniformlygraduated length differences of the pins are equal to one another, and correspond to the spacing of the pins on the receiving body as well as to the gradient of the spiral.
  • a clamping mechanism is associated with each pin and the gear is engaged with an adjusting pinion which is mounted in the receiving body so as to be restrained against axial movement, and having a shaft provided with actuating means accessible from the exterior of the press.
  • the second embodiment of the resetting device has the advantage that, of all the pins, in each case only the shortest one is replaced as soon as its resetting length is used up. After releasing the clamping mechanism, such a pin can easily be removed from its reception bore, and, after turning the disc through one pitch, the worn pin can be replaced by a new pin which then will be the longest pin.
  • a tapped bore is provided coaxial with the larger bore, and a back-pressure screw may be threaded into the tapped bore to release the clamping of the pin.

  • a further object of the invention is to provide such a device in which the down time" for resetting and regrinding the punching pin is reduced to a minimum and is very considerably less than that presently required.
  • Another object of the invention is to provide such a device in which all of the pins can be simultaneously reset through the same radial distance by actuating means accessible from the exterior of the printing press.
