  • the coil spring 26 is fed through opening 24 at a pre-selected spring feed rate.
  • the spring feed rate is determined by the speed at which the spring manufacturing equipment is operated.
  • the spring feed rate will vary widely depending upon the particular equipment being utilized, the type of spring being made and the speed at which the wire is fed into the spring forming die.
  • the coil spring 26 will be rotating about its longitudinal axis as it enters through opening 24.

  • the take-up spool 44 is positioned to receive the coil spring 26 as it is fed into the synchronizing frame 28.
  • the take-up spool is rotated about its own axis at a sufficient rate to take- up the axially rotating coil spring 26 as it enters into the synchronizing frame 28 at the pre-selected spring feed rate.
  • Means for rotating the spool 44 to take up the coil spring is provided by a motor driven drive assembly shown generally at 46.
  • the motor driven drive assembly 46 includes motor 48, drive chain or belt 50 and drive gears 52 and 54.

  • the holding brackets 60 and 62 are shaped to receive and firmly mount the take-up spool for rotatably receiving the axially rotating spring 26.
  • the mounting bracket 62 may be retracted away from spool 44. Retraction is accomplished by pulling handle 64 away from the synchronizing frame 28.
  • the handle 64 is connected to shaft 66 which in turn is connected to the mounting bracket 62.
  • a compression spring 68 is provided to ensure continual bias of the mounting bracket 62 against spool 44 to maintain secure mounting of the spool between the mounting brackets 60 and 62 during winding of coil spring 26 onto the spool 44.

  • the spring guide 72 is shaped to provide controlled feeding of coil spring 26 onto the take-up spool 44. Transverse movement of the spring guide 72 back and forth provides for uniform distribution of the spring onto the take-up spool 44.
  • the threaded shaft 74 is rotatably driven by drive motor 80 which is connected to drive gear 82 which drives gear 84 via belt or chain 86.
  • the spring guide drive shaft 74 is threaded in both directions so that the guide 72 may be controllably moved back and forth.

  • the control panel 88 automatically operates motors 48 and 80 at the speed necessary to provide take-up of spring 26 onto spool 44.
  • the control panel 88 also controls a drive motor (not shown) which rotates synchronizing frame 28 about the same longitudinal axis as the coil spring 26 at the same axial rotation rate.
  • the control panel 88 also includes the necessary electrical equipment and override controls to allow manual control of motors 48, 80 and the motor used to drive rotation of synchronizing frame 28.
  • the rate at which the coil spring is being fed into the take-up apparatus can be visually determined and the rotational speed of take-up spool 44 and translational movement of guide 72 may be manually controlled to ensure a tight and uniform winding of coil spring 26 onto spool 44.
  • the rotational speed of the synchronizing frame 28 may be manually controlled through visual inspection to ensure that the rotational speed of the synchronizing frame 28 is the same as the axial rotation speed of the coil spring to prevent the formation of axial tensions and torquing within the coil spring as it is continually wound onto spool 44.
  • the synchronizing frame 28 is shown as a rectangular frame made from rectangular metal plates which are bolted together. Other frame shapes are possible which can be made from a variety of materials.
  • the location of the mounting collars shown in FIG. 1 can be changed depending upon the location of various elements within the synchronizing frame, such as motors 48 and 80. If the mounting collars 30 and 32 are not located at the rotational center of gravity of the synchronizing frame 28, the frame will be out of balance and result in undesirable vibrations during high speed rotation of the frame. An out of balance condition may be tolerated if the take-up apparatus is intended to receive and wind only coil springs that have a relatively low rate of axial rotation.
  • the above described preferred exemplary embodiment of the present invention can be used to continuously take-up long lengths of axially rotating coil spring. The only limitation is that the equipment must be occasionally stopped to change spools as they become fully loaded with coil spring.

Abstract

Appareil (10) permettant de recevoir et d'enrouler de grandes longueurs de ressort à boudin (26) à rotation axiale sur une bobine enrouleuse (44). L'appareil (10) comprend un cadre de synchronisation ayant une partie avant (38), une partie centrale (40) et une partie arrière (42). Une bobine enrouleuse (44) est montée transversalement dans la partie arrière (42) du cadre de synchronisation (28) afin de recevoir le ressort à boudin (26) au fur et à mesure qu'il pénètre dans le cadre de synchronisation (28). Lorsqu'il fonctionne, le cadre de synchronisation (28) tourne autour du même axe que le ressort (26) à rotation axiale, et à la même vitesse de rotation pour effectuer l'enroulement de grandes longueurs de ressort sur la bobine enrouleuse (44).
