Definitions

  • Sheet feeder for paper processing machines with a separating device that can be adjusted to different sheet thicknesses.
  • the invention relates to a sheet feeder with a sheet separating device, which consists of a rotatably driven friction roller and a retaining member which is radially adjustable with respect to the friction roller and has a braking surface which has a high coefficient of friction and which, together with the outer surface of the distribution roller, has a wedge-shaped passage gap which can be adjusted to the thickness of an arc forms, wherein the shaft of the friction roller extends across the width of a feed path and is connected to a carrier carrying the retaining member by connecting elements arranged laterally next to the feed path.
  • Such sheet feeders are known per se.
  • the retaining element is rigidly fixed in its respectively set position and thus defines a passage gap which cannot be changed until the next setting (DE-PS 1 261 132).
  • the retaining element can also be adjusted with regard to its radial distance from a friction roller, but can be displaced according to the respective setting against the action of a spring force in the sense of increasing the passage gap.
  • the passage gap is set to a certain paper sheet thickness in such a way that such a paper sheet is initially larger Passage gap and stationary roller is placed in this.
  • the passage gap is then reduced until the sheet of paper between the stationary friction roller and the retaining element can only be moved while overcoming a more or less large frictional resistance.
  • the setting is therefore dependent on the feel of the adjuster and is very critical, in particular in the case of thin papers, that is to say insecure, because there is no absolute measure of the adjustment accuracy.
  • the object of the present invention is therefore to remedy this situation and to provide a sheet feeder of the type mentioned at the beginning, in which the required setting accuracy of the passage gap to any sheet thickness of a sheet stack to be processed is to a high degree achievable and in each case by an absolute and objective measuring method is reproducible in the same quality.
  • a radially movable frame is arranged on the carrier with respect to the friction roller and relative to the retaining member, which is provided with a tactile surface that can be placed on the outer surface of the friction roller in the region of the passage gap and an electrical signal switch of a signal circuit has which of the position of the retaining member can be actuated with respect to the sensing surface or the friction roller scanning sensing element.
  • the handling can be carried out in a simple manner in that a paper sheet of the appropriate thickness, to which the passage gap is to be set, is placed in the initially larger passage gap, then the touch surface of the frame is lowered onto the inserted paper sheet, so that the touch surface is circumferential the rubbing roller has exactly the distance corresponding to the sheet thickness and that the retaining member is then adjusted until the signal switch reacts and the signal circuit, for example, lights up or goes out.
  • the electrical signal switch has a contact or switching element, the position of which in the frame is adjustable with respect to the touch surface, and its Counterpart is connected to the probe element.
  • the setting accuracy with which the passage gap between the retaining member and the friction roller can be adjusted to the respective paper sheet thickness can be adjusted or readjusted and adapted to the respective requirements.
  • a structurally very simple, inexpensive, functionally reliable and easy-to-use design of the signal switch can be achieved in that the contact element consists of a contact pin which can be adjusted radially to the friction roller or to the touch surface and in that the contact element has a counter-contact pin which is coaxial with the contact pin in one Bore of the frame is arranged and movably guided and which is pressed by means of a spring force in the direction of interrupting the contact against the retaining member.
  • the frame In order to ensure that the touch surface of the frame is pressed with the same force against the friction roller during each adjustment process, the frame is under the influence of a spring force directed radially against the friction roller.
  • the frame consists of an essentially U-shaped body which has two mutually parallel legs, including the retaining element between them, movably guided on the carrier and a block-like block connecting these legs to one another Has connecting bridge, in which the signal switch is arranged, the end faces of the legs opposite the connecting bridge each forming part of the touch surface.
  • This design of the frame has the advantage that the support surface is divided into two separate sections and each arranged on different sides of the retaining member, each of which has a correct scanning position of the frame with respect to the friction roller and also with respect to that to be scanned by the sensing element Retention organ guaranteed.
  • a further advantageous embodiment of the invention consists in that the frame can be fixed in a position by means of a manually operable latch in which the sensing surface is lifted off the friction roller and the signal switch is locked.
  • the advantage is achieved that the tactile area or the two sections of the tactile area cannot interfere during the normalizing operation which is carried out on the setting, and on the other hand the signal switch can be fixed or locked in a switch position in the raised position of the frame, in which the signal circuit is turned off.
  • the frame is provided with an electrical standby switch which controls the signal circuit of the signal switch, the contact actuating element of which is arranged in the touch surface and can be actuated by the friction roller.
  • this standby switch can also be used, for example, to control a signal lamp in such a way that it lights up as long as the frame is in the key position in which the retaining element can be set to the desired passage gap width with the aid of the signal switch.
  • the stand-by switch consists of a make contact switch and is arranged in one leg of the frame so that its switching pin protrudes from the touch surface in its open switching position.
  • a further embodiment of the invention consists in that the feeler element has a shaft with an end face and / or shoulder surface that is movably guided in a bore of the connecting web of the frame that runs radially to the friction roller, and that the latch consists of a shaft that is axially movably mounted in a transverse bore of the frame There is a plunger, the front end section of which can be pushed into the movement path of the end or shoulder surface of the probe element shaft.
  • the plunger forming the bolt is arranged in the connecting web of the frame so that it interacts with the end face of the probe element shaft and this end face is also the contact surface of the signal switch, then it is expedient to produce the plunger from plastic or at least its front, directly with the End face of the stylus shaft contacting end with an art to provide a material jacket so that the contact switch is interrupted in the locked position of the frame, ie is open.
  • the signal switch is designed as a light barrier and is controlled by a light diaphragm connected to the sensing element, which is arranged in a cavity of the frame between a light source and an optoelectric switching element.
