Description

Printed by Shelley Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7___ 5. Description of the Invention (1) (Technical Field) The present invention relates to a sewing machine for embroidery. In particular, it is related to a sewing machine for embroidery that can be carried out automatically without manual intervention when the thread is changed (sometimes referred to as "thread" or "online" in this manual) or when the thread is broken. (Background Art) Conventionally, in sewing machines for embroidery, processes such as changing color threads or yarn breakage have been carried out manually. However, it is necessary to stop the sewing machine when performing color thread replacement or thread breakage processing. Especially when color thread is implemented, since one embroidery sewing machine usually has a plurality of sewing machine heads, more than 30 sewing machine heads are available. It is necessary to change the color thread for each sewing machine head, so the sewing machine's stop time is up to several hours. As a result, the actual work rate and productivity of the sewing machine are reduced, which is a problem. (Disclosure of the Invention) The present invention solves the problems of the above-mentioned prior art embroidery sewing machines, and provides a method that can be implemented automatically without human intervention in the process of changing color threads or thread breaks. At the same time, this operation requires The time itself can be shortened, and the purpose is to improve the actual working rate and productivity of the sewing machine for embroidery. —A threading device for an embroidery sewing machine, which is characterized by a thread holding member that holds the end of a thread suspended from a thread-feeding pipe, and applies this paper size to the Chinese National Standard (CNS) A4 (210x297)茇) -4- (Please read the precautions on the back before filling this page) -------- Order --------- Line A7 B7 V. Description of the invention (2) The line holding member While the held thread is guided to the vicinity of the needle, the thread is stretched while hanging on the thread stretching mechanism of the scale mechanism; following the thread stretching mechanism, the thread holding member of the wire stretching mechanism is held above the thread holding mechanism. At the same time as the position is hanging the thread, in the state of hanging the thread, it is moved from the upper position to the holding position for embroidery to move horizontally with respect to the thread holding member, so as to hang on the scale of the scale mechanism After the thread is threaded, the auxiliary balance of the scale mechanism that is embroidered at a specific position while the thread is hanging; and is held by the thread holding member of the thread tensioning mechanism for threading to the position near the needle It consists of a threading mechanism through a pinhole. According to the threading device of the sewing machine for embroidery according to the present invention, there is no need to automatically perform a process of changing a color thread or a broken thread through a human hand, which can shorten the time required for the process, thereby improving the actual working rate and productivity of the sewing machine . In addition, according to the threading device of the sewing machine for thorns according to the present invention, while the thread held by the thread holding member is guided to the position near the needle by the thread tensioning mechanism, the thread is stretched while hanging on the scale of the scale mechanism. At the same time, the auxiliary balance of the balance mechanism is driven by the thread tensioning mechanism, and is set at a specific position for embroidery while the thread is hanging. In this way, it can be used on a scale that includes a balance mechanism. Each mechanism of the sewing machine for embroidery of the auxiliary balance and the balance can be moved by a simple mechanism, and the thread can be reliably sent to be set in a state capable of performing the stabbing operation. In addition, the threading device of the sewing machine for embroidery can smoothly feed the thread toward the needle and improve the accuracy of threading. In this case, the threading mechanism is constituted by the thread drawing mechanism and the air nozzle, which can improve the accuracy of threading and simplify the threading.

Claims (1)

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Scope of patent application1. A threading device for an embroidery sewing machine, which is characterized by: a thread holding member that holds an end of a thread hanging from a thread delivery pipe, and While guiding the wire held by the wire holding member to the vicinity of the needle, the wire is stretched while hanging on the wire setting mechanism of the scale mechanism; following the wire setting mechanism, the wire holding of the wire setting mechanism At the same time that the thread is hung by the upper position of the member holding thread, 1 in the state of hanging the thread, it moves from the upper position to the holding position for embroidery to move in a horizontal direction relative to the thread holding element. After the scale of the scale mechanism is hung by the thread, the sub-scale of the scale mechanism that is embroidered at a specific position while the thread is hanging; and is held by the thread holding member of the thread setting mechanism, which is used to hold the guide. A thread to a position near the needle is formed by a threading mechanism passing through the pinhole. 2. The threading device of the sewing machine for embroidery according to item 1 of the scope of the patent application, wherein the threading mechanism is provided with a hook member forming a hook shape at the constitution 'end, and a plug formed on both sides of the hook member. A wire drawing hole and a drawn wire member of a guide member avoiding the needle groove; and an air nozzle composed of a wire insertion hole formed by the wire holding member and the wire held by the wire holding member and fed into the wire insertion hole formed by the guide member of the drawn wire member . 3. If the threading device of the sewing machine for embroidery according to item 1 or 2 of the scope of patent application, the two ends of the thread provided with the threading through hole formed by the guide member of the threading mechanism are guided along the guide A linear pressing mechanism for pressing down the side of the lead member. 4. The threading device of the sewing machine for stabbing according to item 1 of the scope of patent application, wherein an operating lever having a thread cutting mechanism and a hook with a hook at the front end formed with the thread is provided on the wire feeding path; and an operating lever Slidable This paper size applies the Chinese national standard (CNS &gt; A4 specification (210 X 297 mm). 49- A8B8C8D8 6.
