Definitions

  • the invention relates to a device for feeding staple wire to a staple forming device, in particular a stapler attached to a folder arranged downstream of a rotary printing press, with a stationary cutting nozzle, which is penetrated by the staple wire and assigned at least one passing knife as a counter knife, and which uses a staple wire to remove the staple wire upstream feed unit can be fed.
  • receptacles are provided for two supply rolls, of which the staple wire fed to the cutting nozzle or a staple wire held during the processing of the staple wire fed to the cutting nozzle can be unwound with its front end in waiting position in front of the feed unit, and of which a replaceable unit is subordinate, which has two oppositely activated drive devices, each of which one of the the supply rolls of unwindable binder wires are penetrated and can be brought into drive engagement with the respectively assigned clamp wire to bring about a roll change and the drive direction is reversed after each roll change.
  • the no longer processable remaining piece of the wire running out of the used roll can be withdrawn and at the same time the beginning of the wire which can be unwound from the unused roll can be advanced.
  • This process can be carried out within a short time.
  • the number of products with a missing bracket therefore advantageously remains very low.
  • the used supply roll can be removed and replaced with a new one, whereby the wire which has been pulled off can already be put on hold. The time required for this does not have a detrimental effect on production. As a result of the reversal of the direction of the drive device of the changing unit, this is automatically in the correct starting position with each roll change.
  • the drive movement of the drive device can lines of the interchangeable unit are expediently limited so that the feed path to be accomplished in each case corresponds at least to the distance of the front end of the staple wire which remains in the waiting position from the wire engagement area of the feed unit.
  • a particularly simple embodiment of the interchangeable unit can consist of a drive roller arranged in the region between the tangent clamp wires, which can be driven in different directions of rotation, and two pressure rollers which can be adjusted together, by means of which the drive roller can be used to engage with the clamp wires enclosing them is feasible.
  • the drive roller which is reversible from roll change to roll change, together with the two pressure rolls results in two feed devices with opposite transport directions, which can be reversed by reversing the direction of rotation of the drive roll.
  • the end position of the drive roller that is reached with each roll change is therefore also the starting position for the next roll change. Conversion between two roll changes is therefore advantageously dispensed with.
  • a further advantageous measure can consist in that the feed unit and the drive devices of the interchangeable unit can be activated or passivated in opposite directions at the same time by means of respectively assigned actuating elements which can be controlled by means of a common control element.
  • a further expedient measure can consist in that a wire brake device is arranged in the area of each wire passage passing through the exchange unit. This ensures that the wire that remains in the waiting position cannot be transported by vibrations and the like, but is held exactly in the predetermined waiting position.
  • the structure and mode of operation of staplers for stapling interlocking folding products by means of wire staples are known per se and therefore do not require any further explanation in the present context.
  • a staple wire drawn off from a supply roll is fed to such a stapler.
  • the wire feed shown in Figure 1 consists of a feed unit 1 and a roll holder 2. These assemblies are attached by associated carriers 3 and 4 inside or outside of the side wall 6 of the stapler provided with a coaxial wire passage 5.
  • the feed unit 1 is provided with two driven feed rollers 7 and 8, between which the wire to be processed runs.
  • the one feed roller 8 is received on a pivotally mounted lever 9, which is held down by means of an adjustable pressure spring 10 to bring about mutual roller engagement and by means of an actuator 11 designed as a lifting cylinder for lifting the feed roller 8 from the stationary feed roller 7 against the Effect of the spring 10 is pivotable.
  • an actuator 11 designed as a lifting cylinder for lifting the feed roller 8 from the stationary feed roller 7 against the Effect of the spring 10 is pivotable.
  • the wire feed can therefore be interrupted or started without interrupting the drive of the feed rollers 7 or 8.
  • the inlet nip of the feed rollers 7, 8 there is an inlet sleeve 12, via which the start of a wire to be inserted between the feed rollers 7, 8 is reliably brought into engagement with the feed rollers.
  • a so-called cutting nozzle 13 On the enema Bush 12 opposite side is a so-called cutting nozzle 13 also formed by a bush, the end face of which cooperates as a stationary counter knife with a knife moved past it, indicated at 14.
  • the wire feed in the intervals between the successive cuts corresponds to the wire length required to form a clamp.
  • the trestle forming the roll receptacle 2 is provided with receiving devices 15 for zeei supply rolls 16 and 17 formed here by mandrels. These consist of simple plastic drums that can be freely rotated with their hub onto an assigned mandrel.
  • the supply rolls 16 and 17 are processed alternately, so that the one supply roll can be prepared while the other is being used. In the operating position on which FIG. 1 is based, the supply roll 17 is processed.
  • the wire 18 drawn off from this is therefore in engagement with the feed rollers 7, 8 of the feed unit 1.
  • the wire 19 that can be unwound from the other supply roll 16 is held in its waiting position in front of the feed unit 1.
  • the wire feed is stopped, the remaining piece still in engagement with the feed unit 1 is pulled backwards out of the feed unit and at the same time the beginning 20 of the wire 19 that can be unwound from the supply roll 16 is inserted into the feed unit 1, so that with the subsequent activation of the drive rollers 7, 8, the supply roller 16 is now processed.
  • the wire fed to the feed unit 1 runs between Feed unit 1 and roll receptacle 2 in a wire guide 21 which is expediently made of tubular material and which is forked outside the stapler side wall 6 into two branches 21 a and 21 b leading to the two supply rolls 15 and 16, respectively.
  • a change unit 22 is provided which is penetrated by the two wire guide branches 21 a and 21 b and is assembled here with the roll holder 2.
  • this consists of a drive roller 23 arranged in the area between the wire guide branches 21a and 21b forming a fork, which cooperates with two diametrically opposed pressure rollers 24, through which the wires 18 and 19 tangent to the drive roller 23 the drive roller 23 can be pressed and thus brought into drive engagement.
  • By rotating the drive roller 23 about its axis one wire is advanced and the other is withdrawn.
  • the direction of rotation determines which of the two wires is advanced and which is withdrawn, so that the wire running from the finished supply reel can always be withdrawn and the wire from the new supply reel, which is in the waiting position, can be advanced.
  • the direction of rotation of the drive roller 23 changes from roll change to roll change, since the processed supply roll and then the new supply roll is picked up on each of the two receiving devices 15.
  • the drive roller 23, as shown in FIG. 2, is via a shaft 25 connected to a handwheel, which has a crank handle 26 and a disc 28 resting on the housing 27 of the interchangeable unit, which is provided with a segment groove 29 into which a housing-fixed pin 30 engages.
  • a rotation of the drive roller 23 is thus only possible until the pin 30 runs against one or the other end of the segment groove 29, ie at a fixed stop.
  • a further rotation in the same direction is then no longer possible, only a rotation in the opposite direction. This ensures that the drive roller 23 is moved with successive actuation with different directions of rotation.
  • the length of the segment groove 29 also results in a limitation of the drive movement of the drive roller 23, so that the wires 18 and 19 acting thereon are withdrawn or advanced by a defined distance.
  • the diameter of the drive roller 23 is so large that the angle of rotation given by the length of the segment groove 29 results in such a feed path that the beginning 20 of the wire 19 which remains in the waiting position is brought into reliable engagement with the feed rollers 7, 8 and at the same time the remaining piece of the wire 18 is reliably pulled out of the cutting nozzle 13 and the inlet sleeve 12. This is accomplished if the distance between the end faces of the cutting nozzle 13 and the inlet bushing 12 facing away from one another is somewhat smaller than the distance between the front end 20 of the wire 19 which remains in the waiting position and the engagement area of the feed rollers 7, 8, due to the angle of rotation and the diameter the drive roller 23 of the change unit 22 is predetermined.
  • the required insertion length in the area of the wire guide 21 is determined and marked on the wire, here the wire 19, by a clamp 31.
  • the wire can then simply be pushed into the wire guide 21 up to the stop of the clamp 31 on a fixed counter bearing, here on the housing of the interchangeable assembly 22. Then the terminal 31 can be removed.
  • a wire brake device 32 is provided in the area of each wire guide branch 21 a or 21 b.
  • these each consist of a pair of rollers with slightly stiff brake rollers 33, between which the respectively assigned wire is passed and which are pressed against one another by means of a pressure spring.
  • One of the brake rollers can advantageously be lifted against the force of the pressure spring from the counter roller, which facilitates the introduction of a new wire.
  • the roll in question is simply arranged on a correspondingly displaceably mounted rod 34.
  • the pressure rollers 24 assigned to the drive roller 23 are mounted on pivoting levers 35 arranged in the manner of pliers, which here are provided with actuating tabs 36 which extend beyond the pivot point. To the pressing the pressure rollers 24 on the associated pressure roller 23, the actuating tabs 36 are spread apart.
  • an actuator 37 fastened to one of the actuating tabs 36 is provided, which here is simply designed as a lifting cylinder, the piston rod of which can be brought into engagement with the opposite actuating tab 36 when acted upon.
  • the supply lines 38 leading to the lifting cylinders forming the actuators 11 and 37 are turned on and off by means of a common control valve 39.
  • this control valve 39 With appropriate activation of this control valve 39, the feed roller 8 is thus simultaneously lifted from the assigned feed roller 7 and thus the feed unit 1 is passivated and the pressure rollers 24 are pressed against the drive roller 23, so that when the drive roller 23 rotates, the desired wire feed or simultaneous wire retraction takes place.
  • the decrease in diameter of the supply roll, from which wire is unwound, in the operating state of the supply roll 17 on which FIG. 1 is based, is monitored by means of a suitable push-button device, which can be designed as a light barrier or the like.
  • a mechanical push-button 40 is simply provided for this purpose. As soon as this button gives a corresponding signal, the control valve 39 is actuated.
  • the processed supply roll 17 can then be replaced by a new supply roll, the wire of which can be inserted into the wire guide 21 during ongoing operation up to the waiting position of the front wire end defined at 20.
  • this wire is fed to the feed unit 1 and the wire 19 is withdrawn accordingly, the drive roller 23 being rotated clockwise. The change of direction is facilitated by the segment groove 29.
  • control valve 39 should be designed as a manually operable valve.
  • a solenoid valve could also be provided, which can be activated by means of the monitoring device 40 together with a drive motor assigned to the drive roll 23.
  • a drive motor which can be assigned to the drive roller 23 can simply be a synchronous motor which can be switched from left to right and vice versa.
  • an actuatable limit switch can be provided, which switches off the relevant drive motor and switches to the new direction of rotation and at the same time passivates the control valve 39.
