Definitions

  • the invention relates to a shuttle embroidery machine with a Driver bar unit, which has a driver bar, in which for each A lower driver nail and an upper driver nail are arranged, whereby at least one of the driver nails can be moved in the driver bar (see Document EP-A-0 638 681).
  • Shuttle embroidery machines work according to the two-thread system, i.e. with a Needle thread and a shuttle thread, the needle thread with each stitch is devoured with the shuttle thread.
  • One with an ear The needle transports the upper thread through the fabric, where the thread at Retraction of the needle forms a loop. Through this loop, that becomes Shuttle, in which the shuttle thread is contained, passed through.
  • a Shuttle embroidery machine contains a large number of embroidery points and accordingly, many needles and boats.
  • the driver bar is used for the shuttle, which has a lower one for each shuttle Driver nail and an upper driver nail, between which the Shuttle is arranged. With these driver nails, the boat in the Shuttle train of the so-called Stöcklis moves up and down.
  • the Driver beam 11 formed by a steel tube.
  • the lower driver nails 13 are attached to the driver beam 11 with a screw connection.
  • the top Driver nails 15 are slidably mounted in a guide 19.
  • the pressure of a spring 25 can be adjusted to the force regulate against which the upper driver nail 17 can be moved.
  • this is the case at the beginning of a shuttle embroidery machine mentioned type achieved in that the driver bar from a profile exists and that the driver nails are inserted in holes in the profile.
  • the Profile can for example consist of an aluminum alloy.
  • the profile and the holes in the profile can be made with high accuracy, so that the previous complicated adjustment work for the adjustment of the Driver nails are eliminated. This not only represents a significant cost saving, but it also becomes the weight for the previously required fasteners saved for the driver nails.
  • the profile advantageously has latching means, e.g. a groove or a rib on which can cooperate with appropriate locking means of the driver nail to the Lock the driver nail in the desired position.
  • the profile of the Driver beam advantageously has a hollow profile part and two at the bottom Legs arranged on the hollow profile part.
  • the upper driver nail can be in the Hollow profile part and the lower driver nail can be arranged in the legs.
  • On such driver beam has a high stability with a relatively small mass, and Arrangement of the lower driver nail in the legs allows this to be done to manufacture two parts as described below.
  • the driver nail has a detent spring, which with the locking means of the profile can cooperate.
  • the driver nail can have an operating tab.
  • the driver nail e.g. the upper driver nail
  • detent spring and / or Actuating flaps molded in one piece from plastic. This allows one achieve very high cost savings.
  • the lower driver nail can be agents e.g. two opposite each other Have recesses for axially fixing the attachment part and that Attachment part can have two resilient legs for snap fastening on Have a driver nail.
  • the Latching spring means are expediently at the ends of the legs arranged springs formed. This is for the purpose of cost-effective production Attachment part advantageously made of plastic.
  • the actuators are advantageous in a profile arranged, for example, from an aluminum alloy consists. This enables a simple and cheap construction.
  • the profile is a rib, which serves as the axis of rotation for the angle lever, wherein each angle lever has a first arm which is connected to the actuating element is coupled, and a second arm that connects to the lower driver nail can be coupled.
  • the angle lever can be manufactured as a plastic part and leaves snap on the rib.
  • the driver bar 11 of the driver bar unit 10 consists of a Profile, for example a drawn profile made of an aluminum alloy.
  • a Profile for example a drawn profile made of an aluminum alloy.
  • For each embroidery site is a lower driver nail 13 and an upper driver nail 15 intended.
  • To accommodate the upper driver nails 15 are at a distance so-called repeat holes 31 are provided.
  • Below a bore 31 there is a further hole 33 for the detent spring 35 of the upper one Driver nail 15.
  • Locking means e.g. in the form of a rib 39, serve to lock the upper driver nails 15 in the inserted Position.
  • Locking means 40, 41 are for the lower ones Driver nails 13 provided.
  • the profile 11 consists essentially of a hollow profile part 43, of which two legs 45 extend downward.
  • the projections 47,48 serve the Guide of fasteners 51 for fastening the driver beam on Driver beam drive 53 (Fig. 5).
  • the lower driver nail 13 could be the same as or similar to the upper driver nail be trained if space permits.
  • the lower driver nail 13 consists of a pin-shaped one Part 13, the recesses 61 on two opposite sides having. After inserting the driver nail 13 into the driver bar 11 can the attachment part 63 be placed in the area 61, wherein it in the groove 41 of the profile 11 engages and axially fixes the driver nail 13 (FIG. 4).
  • the Attachment 63 has two resilient legs 65 for snap fastening on Driver nail 13.
  • the driver bar unit 10 ' differs from that of Figures 3 and 4 in that the lower driver nail 13 displaceable in the driver beam 11 for decommissioning is. This is achieved in that instead of the attachment part shown in FIG. 3 63 the attachment part 67 shown in FIG. 5 onto the lower driver nail 13 is put on.
  • the attachment part 67 has resilient legs 65 ', on the other Ends 69 are integrally formed springs. The one with such an attachment 67 equipped lower driver nail 13 can therefore in the driver beam 11 are displaced, the springs 69 engaging in the grooves 40 and 41 can to the driver nail 13 in the corresponding locking positions hold.
  • the actuation tab 71 serves to shift the driver nail 13.
  • Control unit of the shuttle embroidery machine controllable actuating element 73 e.g. a pneumatic cylinder is provided.
  • This cylinder 73 is in one Profile 75, e.g. made of an aluminum alloy.
  • This profile has one Rib 77, which serves as the axis of rotation for an angle lever 79.
  • This owns a first arm 81 which is coupled to the piston 83 of the cylinder 73.
  • the second arm 85 can on one side or the other on the tab 71 of the Attack lower driver nail 13 to shut down the boat, or again to activate.
  • Driver beam units When testing embroidery machines with those described above Driver beam units have been shown to operate at very high speeds can be driven without strong vibrations. It is advantageous also that cost of the driver beam units at a fraction of the cost could be reduced for a conventional driver beam unit.
  • the shuttle embroidery machine has a driver bar unit 10, the Driver beam 11 from a drawn profile, e.g. made of an aluminum alloy, consists.
  • a driver bar unit 10 the Driver beam 11 from a drawn profile, e.g. made of an aluminum alloy, consists.
  • the upper Driver nail 15 together with detent spring 35 and actuating tab 57 is in one piece, e.g. molded from plastic.
  • In the retracted position of the driver nail 15 can engage the detent spring 35 on a groove or a rib 39.
  • On the lower driver nail 13 can be inserted into the driver bar 11th either a mounting part 63 or a mounting part 67 can be snapped on. With the attachment part 63, which engages in the groove 41, becomes the driver nail 13 blocked.
  • the driver nail 13 With the attachment part 67, the driver nail 13 remains displaceable but with the springs 69, which can engage in grooves 40, 41, in two different positions are secured.
  • One from the embroidery machine controllable actuating element 73 serves to actuate the lower one Driver nail 13.
  • the driver beam is very inexpensive to manufacture and has a low mass, which allows high embroidery speeds.
