Problems solved by technology

[0002] At present, the bottom thread of the computer embroidery machine in use is composed of a bobbin case and a bobbin. When the embroidery machine runs out of bottom thread, the bobbin case (bobbin) needs to be replaced. Now all of them are replaced manually. , the embroidery machine should be completed in the shutdown state
There are the following problems: the embroidery machine needs to stop for 12-20 minutes every day for a single machine head to replace the bobbin case (bobbin). Reduce embroidery machine output
But this type of equipment in the prior art only utilizes the mechanical execution part to complete bobbin case dismounting and the operation according to
[0004] Problem 1: The disassembled empty bobbin case is placed in the receiving hopper of the device and needs to be recovered manually
And the bobbin case used for replacement on the device also needs to be supplemented and maintained in time. Since the shuttle body, machine head and related configuration components on each station of the embroidery machine are closely arranged, the operator leans over to recover and

Abstract

The invention provides a bobbin case replacement device. A plurality of bobbin case storage stations can be arranged and used for storing dismantled bobbin cases and standby bobbin cases, the continuous work time of the bobbin case replacement device can be prolonged, when the standby bobbin cases on bobbin case storage devices are used up, an operator can directly replace the bobbin case storagedevices to supplement the standby bobbin cases, and the work efficiency is greatly improved. Each bobbin case storage device comprises a storage rotary disc and several bobbin case storage stations surrounding the storage rotary disc, and the bobbin case storage stations comprise mandrels used for placement of the bobbin cases; the mandrels are fixedly connected to the side surfaces of the storagerotary discs in the axial directions of the storage rotary discs; a bobbin case locating piece and a thread head clamping structure are respectively installed on the two sides of each mandrel. The invention further provides the bobbin case replacement device, a bobbin case replacement system and a bobbin case replacement method based on the bobbin case storage device.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to the technical field of automatic bobbin thread changing and bobbin case changing for embroidery machines. Background technique [0002] At present, the bottom thread of the computer embroidery machine in use is composed of a bobbin case and a bobbin. When the embroidery machine runs out of bottom thread, the bobbin case (bobbin) needs to be replaced. Now all of them are replaced manually. , the embroidery machine should be completed in a stopped state. There are the following problems: the embroidery machine needs to stop for 12-20 minutes every day for a single machine head to replace the bobbin case (bobbin). Reduce embroidery machine output. [0003] Existing multi-head embroidery machine is that a row of head stations is set on its frame, a shuttle case is set at each head station, and a head for installing the bobbin case is set in the shuttle case. The bobbin case is pro...
