Abstract

PURPOSE: Provided is a continuous supplying device of bottom yarn by an improved bobbin case which is characterized by inserting bottom yarn into a tension regulator installed on an inner case. CONSTITUTION: The continuous supplying device of bottom yarn by the improved bobbin case is comprised of: a supplying pipe(5) of bottom yarn set up in a rotating axis(4); a bobbin box got with the inner case(3a) in a body; a hole which is formed on the front of the bobbin box, meeting with the supplying pipe(5) of bottom yarn; a guiding hole of bottom yarn formed on the upper part from the hole; and the tension regulator of bottom yarn installed on the upper part of the guiding hole.

Description

Continuous bobbin feeder by improved kiln {.}

The conventional sewing machine is a method of replacing when the lower thread is exhausted in the book. It is intended to be used continuously without replacement.

There have been several studies to continuously use the bobbin thread without replacing it. Among them, the idea of inserting the lower thread insertion tube into the rotating shaft has been out for a long time. Since then, a number of designs rooted in this design have emerged. For example, FIGS. 3 and 4 are attached.

In the case of Figure 3, the lower thread supply pipe (⑤) is placed in the rotating shaft (④), and the lower thread is inserted therein, and the central shaft member (3) of the inner kiln (③a) ) The lower thread is pulled out by the guide groove (⑮) and passed through the lower thread tension device of the bobbin (①).

In the case of Figure 4 through the lower thread supply pipe through the empty space next to the central shaft member of the inner hook (③a) is a way to take the lower thread into the bobbin.

In addition to this, there is a method of making a hole in the support of the central shaft member and drawing out the lower thread there.

Various conventional designs have been used in which the lower thread is taken out by the lower thread supply pipe (⑤) and guided to the bobbin (①) through the inner kiln (③a).

In the present invention, the inner thread (③a) and the bobbin (①) do not rotate, so the idea that the inner hook (③a) together to function as the bobbin bobbin thread through the lower thread supply pipe (⑤) ready to sew through Waiting in the state.

As mentioned in the above prior art, the process of passing the lower thread supply pipe (⑤) in the rotary shaft (④) is almost the same. However, there were various ways in which the lower thread passed through the lower thread supply pipe (⑤) was placed in a waiting state for sewing.

The present invention is to make a hole from the center lower side of the front of the inner kiln (③a) with the body of the inner kiln and the bobbin, which meets the lower thread supply pipe (⑤).

And the front part of the inner part of the inner part of the inner part ) And bobbin thread groove ( ) And the lower thread guide groove ( To the lower thread tension adjustment piece ( ) Was attached.

This inner kiln is placed in the existing outer kiln (③b) and filled with the inner hook separation prevention cover (③c) and fixed to the rotating shaft (④).

(The support that does not rotate the inner hook when rotating the outer kiln is not shown)

In this way, the lower thread through the lower thread supply pipe (⑤) is the inner hole (③aa) front hole ( Through the lower thread tension adjusting piece ( Pass the bottom and enter the waiting state for sewing.

While the existing designs go through various processes in which the bobbin thread taken out from the bobbin supply pipe is inserted into the tension adjusting device of the bobbin and attached to the hook, the present invention attaches the bobbin thread taken out through the kiln to the kiln. It is easy to perform the work by using a simple way to complete the waiting state of sewing by inserting the tension control device

Claims (1)

In the bobbin thread continuous feeding device with the bobbin thread feeding pipe into the rotary shaft, the bobbin is made of one body with the inner hook to make a hole in the front to meet the bobbin thread feeding pipe, and to make the bobbin threading groove upward from the hole and tension the bobbin thread on the guide groove. Lower thread continuous feeder using an improved new kiln with adjustable piece.
