Definitions

  • the invention relates to a device for looping a continuous wire to a wire comb with loop-shaped sections of substantially hairpin-shaped bent and adjacent tines and with the loop-shaped sections connecting, extending in the longitudinal direction of the wire comb and successively arranged wire sections, with two spaced apart and synchronous moving pin carriers, each carrying a number of consecutive pins in the direction of movement, wherein the rows of pins have substantially the same pitch, but the pins of the two rows of pins are offset in the direction of movement of the pin carrier against each other, and with a rotatably mounted about an axis of rotation loop loops for loop-laying the wire in turn alternately around a pin of a row of pins and a pin of the other row of pins.
  • Wire combs of the aforementioned type are used in particular for binding the paper blocks by the wire combs after their manufacture by a device of the aforementioned type in subsequent or downstream Devices are first pre-bent C-shaped and divided into wire comb sections and then inserted and closed in the introduced in the region of a side edge of the paper blocks holes.
  • a device of the type mentioned is from the DE 10 2006 015 809 A1 and the corresponding one EP 1 842 606 A1 known.
  • the rotatably mounted loop puller has two arms and a central head part, from which the two arms extend diametrically outwards.
  • the loop puller is arranged not only rotatable about its axis of rotation, but the loop puller or at least the central head part is also movably mounted in the axial direction, relative to the axis of rotation of the loop puller, said movement being radial with respect to one of the two pin wheels and thus to the the pin row carrying circumference of this pin wheel is oriented. This movement can be reciprocal.
  • the head part can be moved in the direction of the pin row of the pin wheel and away from it. In this way, it is possible to bring the head part in abutment with two adjacent pins of the pin wheel to press during this movement, the wire in the gap located between these two pins and to close for receiving the corresponding portion of the wire substantially. This ensures that with continued rotation of the loop puller for the subsequent bending or bending process, the wire is held in the gap and unintentional slipping out of the wire is prevented from this gap.
  • the head part is provided as an axially reciprocally movably mounted plunger and serves as a first stripping element. Further, a further stripping element is used to transfer the hairpin-shaped curved, prong-shaped portions of the wire on the pins of another pin wheel. This second stripping element is formed in this known device as a cup-shaped swash plate.
  • the invention proposes to use a stationary arranged guide element, which is designed for the guided engagement of the wire in at least one row of pins.
  • a guide element according to the invention requires a much simpler construction than the use of a movably mounted plunger or even a movably mounted loop puller with a designed as a plunger head part.
  • the loop puller is also fixed in relation to the pin carriers and only requires a rotatable support for looping the wire.
  • the invention leads to a simpler and less expensive construction and at the same time to a more effective and reliable operation of the device.
  • means for the rotationally fixed coupling of the axes of rotation of the two pin carriers can be used.

  • the angular arrangement of the axes of rotation of the two pin wheels should be adjustable.
  • a further preferred embodiment of the invention which has at least one scraper for transferring a bent wire section from the loop puller to a pin of one of the two pin carriers, is characterized in that the scraper is designed as a rotatably mounted, substantially circular disc which along along its circumference a control curve is provided which has at least one protruding portion which comes into contact with the bent wire section on the loop puller and pushes it with continued rotation of the disc from the loop puller on a pin of a pin carrier.
  • a drive device which sets the wiper in a rotation which is synchronized with the movement of the pin carrier so that the at least one projecting portion of the control cam of the wiper with a bent wire section on the loop puller comes into contact and this from the loop puller presses on a pin of a pin carrier when the angular speed of the loop puller reaches a minimum.
  • the scraper is designed as a cup wheel, whose raised in the axial direction edge forms the control cam.
  • the scraper may be formed as a swash plate.
  • the axis of rotation of the scraper is to be arranged substantially parallel to the axis of rotation of the loop puller.

  • the loop puller 12 is provided in the illustrated embodiment with two with respect to the rotation axis 15 diametrically arranged arms 16, 18, wherein on the first arm 16, a first bending cam 20 and on the second arm 18, a second bending cam 22 is seated.

  • This operating state is in FIG. 1a shown.
  • the first bending cam 20 takes the wire 10 with it, whereby the bending process begins. This is FIG. 1b shown.
  • Figure 1c indicates that the bending process is almost completed after the first bending cam 20 almost a semicircle movement relative to the state of FIG. 1a has completed. Subsequently, the first bending cam 20 reaches one opposite its position FIG. 1a pivoted by 180 ° position, a transfer of bent from the first bending cam 20 wire section takes place on a corresponding pin 6 of the first pin wheel 2. Here, the scraper 24 is used, which transfers the bent wire section from the first bending cam 20 on the corresponding pin 6. By the way, this transfer is in relation to the second bending cam in FIG. 1 a recognizable. At the same time the second bending cam 22 engages behind the continuously tracked wire 10 at the same previously explained point as the first bending cam 20 according to FIG FIG. 1 a.

Subsequently, the distance between the pins 6, 8 becomes smaller again, which allows a low-friction decrease of the thus formed wire comb of the pins 6, 8, to supply the wire comb for further processing.
