Definitions
- the invention relates to a device for feeding a rubber band or the like in the sewing area of a sewing machine, with a stepper motor driven conveyor for the Belt feed, a cutting tool for cutting the Tape and a tape outlet for the tape handover to the Sewing machine, being a conveyor belt, the one with a relatively adjustable Co-operating support strand has the tape outlet.
- the band brake can only approximate the bias of the cut end portion when Sew on the tape, making irregularities have to be accepted when the tape is fed.
- the emerging not only bring different tension ratios uneven gathers and loops with it, but they also prevent an exact predetermination of the sewing length of the tape, an exact alignment of the tape and a flawless Overlap or butt the tape ends when sewing on on tubular workpieces.
- the invention solves this problem in that the conveyor for the belt feed and the belt conveyor for the belt transfer consist of a common conveyor, the cutting tool is subordinate and a circulating until immediate Includes conveyor belt projecting to the sewing area a front pulley up to which the conveyor run and extend the associated counter bracket, the tape outlet certainly.
- the tape flat up Conveyor line leading directly to the sewing area gives what ensures optimal alignment of the belt and through the tape holder until just before sewing on that too cut the tape end under the same conditions the sewing area feeds like continuous band sections.
- a counter bracket is suitable for this slide adjustable against spring force, the on its side facing the conveyor belt conveyor devices has, so that by the resilient Irregularities occurring in the sled ) Tape can be compensated for and without loss of adhesion a suitable tape guide is provided.
- the tape guiding devices themselves are dependent on the circumstances to coordinate, using simple slideways as guide devices, Guide rollers, circumferential counter holder belts and. like. can be provided together with the driven Conveyor belt ensure perfect belt feed.
- the carriage can be correspondingly wide reset and lift off the conveyor belt.
- the conveyor advantageously has a feeder with one Rubber band holder, which is in the feed direction in front of the Starting tool lying in a starting position in the conveying area of the conveyor engaging feed position can be moved forward is stored, the rubber band holder from two that Rubber band between the receiving, arranged on a swivel arm Guide tongues can exist.
- This feeder is an automatic after cutting a piece of rubber band It is possible to insert the new beginning of the band because the rubber band holder holds the remaining tape after cutting and if necessary by moving forward into the funding area of the conveyor the cut end of the belt as a new beginning Conveyor passes, so that the conveyor then the further tape take-off and can take over the tape feed.
- a constructive Low-effort rubber band holder is created when two guide tongues grasp the tape between them and by means of a Swivel arm from the starting position to the feed position are pivotable, the guide tongues, which in Project the feed direction freely, pulling the belt through allow unimpeded in the feed direction, a possible Withdraw the tape after cutting to length but through the Prevent protruding, barb-like tongue tips.
- a sewing machine 1 For sewing a rubber band B onto a workpiece W, for example as a waistband of a pair of panties, shows a sewing machine 1 with sewing needle 2, presser foot 3, sewing table 4 and no further shown workpiece feed a device 5 for feeding the rubber band B in the sewing area of the sewing machine 1 on, the device 5 a conveyor 6 for the tape feed, a cutting tool 7 for cutting the tape to length and one right up to the area of the presser foot 3 outstanding tape outlet 8 for tape transfer to the sewing machine 1 includes.
- the conveyor 6 is the cutting tool 7 downstream in the feed direction and with one over one Stepper motor 61 driven rotating conveyor belt 62, which conveyor belt 62 a through two pulleys 63, 64 has specific conveyor run 65, with a counter-holder 9 cooperates to form the conveyor line.
- the front deflection roller 64 also determines the Belt outlet 8, so that the belt with the conveyor 6 to immediately is led into the sewing area.
- the counter bracket 9 consists of a sliding adjustable Carriage 91, which in the direction of the conveyor 65 with a Pressure spring 92 is loaded and against the force of this pressure spring 92 by means of an actuating cylinder 93 for insertion a tape can be opened.
- a sliding adjustable Carriage 91 which in the direction of the conveyor 65 with a Pressure spring 92 is loaded and against the force of this pressure spring 92 by means of an actuating cylinder 93 for insertion a tape can be opened.
- belt guiding devices on the slide side, for example a guideway 94.
- the cutting tool 7 has a standing counter knife 71 and a movable scissor knife 72 and allows a cut the rubber band B in the feed direction in front of the conveyor 6, so that the conveyor belt B by a not shown Supply spool is removed, practical for cutting to length can be cut without tensile load.
- the counter holder 9 closes the band end is gripped by the conveyor 6 and can be drawn in while the feeder 10 swings back into the starting position. A new sewing process can begin.
