Definitions
- the invention relates to a machine for automatically changing bobbin bobbins for, in particular, lockstitch sewing machines with an interchangeable head which removes an empty bobbin from a lower part of the sewing machine and supports a full bobbin.
- DE-PS 886 115 relates to a bobbin with a turret for automatic bobbin change and a thread-knotting device.
- the invention has for its object to provide a machine for automatic replacement of bobbin bobbins, in particular for lockstitch sewing machines, which in connection with a bobbin winding
- Ersa automat can be used with high-speed industrial sewing machines and is characterized by high precision and reliability.
- the machine according to the invention makes it possible to automatically replace empty bobbin bobbins with full bobbins even in high-speed industrial sewing machines.
- Figure 1 is a plan view of the replaceable head of the machine.
- Fig. 2 is a schematic view of additional facilities on the magazine.
- FIG. 1 shows a plan view of the replaceable head 27 of the machine, which is the most important part.
- the Exchangeable head 27 works together with a spool magazine 22 (FIG. 2) by taking full spools 2 from it and after a pneumatically effected rotation about a vertical axis of rotation 40 of the exchangeable head 27 with its longitudinal axis 39 in the axis of the gripper (bobbin case carrier)
- the sewing machine swings in and the full bobbin 2 with the bobbin case carrier lower part 35 is inserted.
- the interchangeable head 27 can be moved out laterally on a carriage 26, ie can be moved away from the sewing machine in the axial direction 39.
- the interchangeable head 27 has a receptacle 34 for the bobbin case carrier 35.
- a resilient shaft extension 37 is arranged in this receptacle 34.
- connection for example a pawl 38
- the connection is released between the two parts of which the bobbin case carrier usually consists, so that the bobbin case carrier lower part 35 with the bobbin 2 can be removed from the sewing machine .
- the interchangeable head 27 is arranged to be tiltable about a horizontal axis 41.
- a second interchangeable head 27 ' can be arranged on the slide 26 in the longitudinal axis 39 or also at an angle thereto, which makes it possible to swivel the first interchangeable head 27 with an empty coil 2 in the lower part 35 of the bobbin case carrier Insert bobbin case carrier lower part 35 'with a full bobbin 2'.
- the interchangeable head 27 can be rotated further about its longitudinal axis 39 by means of a pneumatic adjusting cylinder 42 in order to be able to thread the thread of the bobbin 2 into the lower part 35 of the bobbin case carrier.
- Figure 2 shows a schematic representation of additional facilities on the magazine.
- the interchangeable head 27 transfers the empty reel 2 to a magazine rod 57, whereupon the interchangeable head 27 swivels to the side 58 of the magazine 22 for full reels 2 in order to grip a full reel.
- a suction nozzle 61 is attached to the side of this magazine 22 and sucks in the thread hanging out of the slot 59.
- a pair of pliers 62 is provided which can be actuated pneumatically and tensions the thread in such a way that the thread is automatically threaded when the interchangeable head 27 is pivoted through 90 °.
- the pneumatic pliers 62 then perform a movement to release the thread, whereupon the interchangeable head 27 inserts the full bobbin 2 into the sewing machine after a 90 ° swivel.
