Definitions
- the invention relates to an additional device for initial sewing Thread chain with a sewing table, a stitch plate and an edge cutter Chainstitch sewing machine, with one downstream of the stitch plate in the sewing direction Suction and separation device for catching and cutting the thread chain after sewing a workpiece, a return device for swiveling of the remaining thread chain end piece against the sewing direction and one of the Stitch plate in the sewing direction upstream clamping and deflection device for holding of the pivoted thread chain end piece and for its lateral deflection down to the cutting area of the edge cutter.
- the invention is therefore based on the object to eliminate these shortcomings and a To create additional device of the type described, which with proportion low construction and construction effort a clean and reliable starting sewing allows a thread chain.
- both the return device and the clamping and deflecting device forming thread chain gripper is provided, which consists of a sewing direction longitudinally movable gripper pliers and a pliers carrier which can be moved transversely to the sewing direction consists.
- This thread chain gripper not only takes over the function of the return device, but also that of the clamping and deflecting device, the thread chain during the entire movement process from swiveling to sideways movement and cutting to length is held or guided in the gripper and itself thereby achieving perfect initial sewing without risk of malfunction.
- the gripper needs which then by means of the existing suction and separation device behind the The throat plate is kept ready, only advance in the sewing direction and with the hook pliers to grasp the thread chain, whereupon moving back forcibly and without Using compressed air or the like, the thread chain swings around and into the sewing position brings what the tong holder only needs to be moved laterally to the end of the thread chain can be shortened accordingly with the edge cutter, and when Sewing the next workpiece automatically turns the shortened thread chain end piece sewn with.
- a particularly useful construction results when the gripper tongs two in Plier parts guided parallel to one another in the longitudinal direction and adjustable with as Pliers mouth cooperating clamping edges in the front end area, which Pliers parts with the pliers mouth from a basic position lying in front of the needle plate Sliding adjustable up to the suction opening of the suction and separation device behind the throat plate are.
- These two pliers parts can be gripped by simple actuators and release the thread chain are operated and allow at the same time with it Longitudinal adjustment swiveling the thread chain end against the sewing direction as a prerequisite for the initial sewing.
- the pliers part protruding in the sewing direction forms an oblique one at the front end Thread deflector edge, when the gripper pulls forward, the one from the Sewing needle pushing down the thread pushed to the side, which disturbances and getting stuck avoids the thread.
- This deflector edge also helps the thread chain end, to slide sideways into the pliers mouth.
- the pliers parts are made of leaf springs, which extend from the top of the sewing table to one Sheet guide are deflected downwards and provided on one on the underside of the sewing table
- the guide and drive parts for the gripper tongs can attack the actuator space-saving below the sewing table and the flat design the pliers parts as leaf springs avoid impairment of accessibility in the sewing area.
- the actuator has one horizontal transverse axis on an adjustable dial, on the circumference of which one Leaf spring is attached, with a coaxial relative to the adjusting disc Adjusting lever engages the other leaf spring, which is loose on the adjusting disc or the first leaf spring rests.
- the structural conditions are good pliers carrier construction that is adaptable to a sewing machine with sufficient large lateral movement range.
- Suction and separation device 5 for catching and cutting the thread chain after sewing a workpiece is with an additional device 6 for initial sewing a thread chain, which consists of a sewing direction N in front of the needle plate 3 arranged thread chain gripper 7 consists of one in the sewing direction longitudinally movable gripper tongs 8 and one which can be moved transversely to the sewing direction N.
- Pliers holder 9 is composed.
- the gripper tongs 8 comprise two parallel to one another in the longitudinal direction and relatively adjustable guided pliers parts 81, 82, which consist of leaf springs and as pliers mouth 83 cooperating clamping edges 84, 85 have in the front end region. Furthermore the lower pliers part 81 protruding in the sewing direction forms one at the front end inclined thread deflector edge 86. The pliers parts 81, 82 are over a Sheet guide 87 deflected from the top of the sewing table to the bottom and grasp here to an actuator 10, which is rotatable about a horizontal transverse axis H.
- Setting disc 101 on the circumference of which a leaf spring 81 is attached, and one for Adjustment disk 101 has coaxial relatively pivotable lever 102, on which the other loosely resting on the first tong part 81 engages the second tong part 82.
- the pliers parts 81, 82 with one another or via one Adjust cylinder 103 relative to each other in the sewing direction N or the desired length Carry out pliers movements.
- the tong holder 9 receiving the gripper tongs 8 is designed as a swivel arm 11, which is supported on the sewing table 2 so as to be pivotable about a vertical axis V.
- the Swivel arm is in two parts and consists of a carrier part 111 for the gripper tongs 8 and a support part 112 articulated thereon for support on the sewing table 2.
- the two-armed spring-loaded can thus be actuated by an actuating cylinder 113, which is only indicated Swing arm 11 up and down like scissors and thus a transverse movement reach the gripper 8.
- the gripper tongs are 8 in retracted the basic position of the thread chain gripper up to the needle plate 3 and the stitch plate 3 is completely freely accessible for the sewing process (Fig. 4).
- the gripper tongs 8 moves together with both tongs 81, 82 to the stitch area, with the downward thread over the Thread deflector edge 86 is laterally deflected (Fig. 5).
