Embodiment Construction

[0014] exist figure 1 Among them, the process of automatically changing the bottom thread is: first, the manipulator 2 clamps the spare bobbin, and the transfer mechanism transfers the manipulator 1 to the position aligned with the hook and takes out the empty bobbin, and then the transfer mechanism transfers the manipulator 1 and manipulator 2. The position is reversed so that the spare bobbin is aligned with the hook, then the manipulator 2 puts the spare bobbin into the hook, and at the same time the manipulator 1 releases the empty hook so that it falls into the recovery device. Finally the whole device is reset.

[0015] exist figure 2 Among them, the automatic bobbin thread replacement device is mainly composed of three parts: base 3, lead screw transmission part 4 and workbench 5. Place the actuator for changing the bottom line on the workbench 5, which is made up of manipulator 1, manipulator 2, rotating shaft 6, belt seat bearing and motor 7, etc. After the device...

Abstract

The invention provides an automatic bobbin thread changing device for an industrial sewing machine. Two manipulators are employed for grabbing empty bobbins and standby bobbins respectively. The device mainly consists of three parts, which are a pedestal, a screw transmission part and a workbench. An execution mechanism for changing bobbin threads is placed on the workbench and consists of a manipulator 1, a manipulator 2, a rotating shaft, a mounted bearing, a motor and the like. The device is high in reliability and easy to realize; the rotating mechanism is used for grabbing and changing bobbins; after change, a translation mechanism takes the execution part of the device to a safe scope so that the execution part does not interfere with the work of an automatic production line.

Description

technical field [0001] The invention relates to an industrial sewing machine bobbin thread technology, in particular to an industrial sewing machine automatic bobbin thread replacement device. Background technique [0002] Industrial sewing machine is a kind of production equipment widely used in all walks of life. The lock stitches sewn by it are formed by the interweaving of the upper thread and the lower thread under the action of the needle, hook thread and jumper mechanism. Among them, the upper thread (also known as needle thread) is supplied by the continuous supply of large thread balls. Because the thread volume of large thread balls is more than 5000m, the continuous thread supply time is long and the replacement frequency is small. Generally, it is only replaced once per shift. The bottom thread (also known as the bobbin thread) adopts the method of bobbin thread supply, the bottom thread is wound on the bobbin, then the bobbin is put into the bobbin case, and the...
