Abstract

PURPOSE:To always properly wind thread, by pinch-holding a bobbin between a headstock and a tailstock. CONSTITUTION:An automatic thread winder comprises a tailstock 52 movable back and forth and a headstock 51 for rotating a bobbin. The tailstock 52 and the headstock 51 are coaxially opposed to each other. The tailstock 52 comprises a spindle and a cylinder which are movable relative to each other in the axial direction. In the normal winding of thread, the bobbin is pinch-held between the spindle and the headstock 51. When the to-be-held end part of the thread is wound on the bobbin, the thread and the bobbin are pinched between the cylinder and the headstock 51. Just after the stoppage of the rotation of the headstock 51, the cylinder is moved forth to pinch the bobbin between the cylinder and the headstock 51.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic thread winder that automatically and continuously winds thread around a bobbin for bobbin used in multi-head embroidery machines and sewing machines.

The present invention relates to improvements in the structure and operation of the tail stock that holds the bobbin together with the head stock in the bobbin winding section.

Also in the conventional example 1IC such as the invention described in Japanese Patent Publication No. 54-25138, the tail stock is mainly composed of a spindle and a cylinder that can move in the relative axial direction, and the head stock and the tail stock are separated. The bobbin and thread can be detachably held between the bobbin and the thread. However, in the conventional example, the tip retaining portion of the spindle is engaged with the retaining portion of the headstock so that both rotate together, and a compression spring is embedded in the outer periphery of the spindle tip. The structure is such that the movement of the bobbin in the rotational direction and axial direction is restrained by frictional engagement with the inner circumferential surface of the hole of the bobbin, so that the bobbin can be held on the spindle. Therefore, in the conventional example, the structure is complicated, such as requiring crimping, and the device as a whole is prone to failure due to long-term use.
The retaining part of the spindle tip and the retaining part of the headstock may not be smoothly engaged, and when the headstock is stopped (it is necessary to stop suddenly), both retaining parts There is a risk that an impact may be applied between the parts, leading to failure of the part.

The present invention aims to eliminate the various deficiencies of the above-mentioned conventional examples. □ Hereinafter, embodiments of the present invention shown in the drawings will be specifically described based on C.

By turning the headstock (51), the pobbin (1)
When the thread (e) is wound around the thread (e), the lever (61) rotates in the opposite direction according to the numbered amount, and when the number of windings (k) reaches a predetermined value, the machetor (64) rotates. When the lower limit is reached, the microswitch (LS6) is in the state shown in the electrical schematic diagram of FIG.

As a result, the take-up motor (Ml) stops, while the camshaft motor (M2) rotates, and a series of subsequent operations result in revolving, winding (a), ? This is because various operations such as replacement operations are performed. As shown in Figure Is9, when the tailstock (52,) is retracted and the bobbin (town) can be dropped, the lever (61,) is moved by the actuator (6
It is rotated in the j direction by the restoring force of 4).・At this time, when the restoring force of the actuator (64) acts on the bobbin (a') K via the lever (61) and knocks the bobbin (1) off, the falling position and falling position The position afterward may be different from the expected one, and the thread (e) is attached to the flange of the bobbin (1)) and the end face of the tailstock (5G).

As shown in the electrical circuit diagram of FIG. 8, a buzzer (32) is provided to notify this fact.

No. 1: Shown (21) is the force A axis (2) K11 attached '*1 cam, which has a circumferential part (24) and a straight part (25), and is the starting point of the winding motor (Ml). IEII? It detects points. Normally (when the camshaft (2) is stopped), as shown in Fig. 1, the microswitch (LSI) K placed around the first force A (21) is not in contact with the straight part (
25) is a microswitch (LSI) opposite to K,
Circumferential portion (24) of the first cam (21) for rotation in the P direction
touches the microswitch (LSI) and presses it.
Then, switch the switch to the No side shown in the electrical circuit diagram of FIG. However, in this case, the thread amount detection switch (LS6
) is on the opposite side, so the microswitch (LSI)
Regardless of the switching direction, the winding motor (Ml) remains stopped. Afterwards, due to the fall of the bobbin (1), the thread amount detection switch (LS6) switches to NC@K, but in this case as well, since the microswitch (LSI) is on the No side, the winding motor (Ml) remains stopped. It is. 1st
The cam (21) rotates nearly 3sf, and its straight part (25)
When the force (the microphone switch (LSI) reaches position 1, this microphone switch (LSI)

21) rotates by a slight angle and then stops. -- (23) shown in Fig. 1 is the third cam fixed to the camshaft (2)), which has a circular part (26) and a straight part (not shown).
There is a device that has a camshaft origin and detects the camshaft origin.

Normally (when the cam (d) (2) is stopped →, the front arrangement line part is a micro switch (LSI)
= Yes, the micro switch (LS3) is connected to the fs3 cam (2

There is K. When the thread loss detection switch (LS6) is switched to the No side, the camshaft (2) rotates in a U direction, and the third cam (23)
When the microswitch (LS3) rotates by a slight angle, its circumference (26) comes into contact with the microswitch (LS3) FC and presses it, so this microswitch (LS3) 1iNOI
Switch to Il. Therefore, even if the yarn amount detection switch (quotient) is switched to NC@, the camshaft motor (M2) continues to rotate. When the third cam (23) rotates once and the straight part comes to the position facing the microswitch (LS3) again, the microswitch (LS3) is switched to iNclII, and the camshaft motor (M2) is rotated. is the camshaft (2)

FIG. 18 is an electrical circuit diagram showing the electrical connections of various types of microswitches and motors used in this embodiment. In this circuit diagram, 4 (sw) is the main switch, (ω-address counter, (1) is the toggle, (g) is the indicator light -1 (1) is the power supply, and the other components are as already described. .

FIG. 19 is a timing table showing the interrelationships of the operations of various motors, microswitches, force/motors, and main components in this embodiment, with the rotation angle of the camshaft (2) on the horizontal axis. This timing table more specifically describes the operation of the main components already mentioned.

This is to compensate for the fact that some of the explanations have been omitted and some of the explanations have been omitted.

As shown in the above-mentioned embodiment, the present invention has a tail stock that can move forward and backward and a head stock for driving bobbin rotation, which are arranged opposite to each other on the same axis, and the tail stock is automatically moved in the relative axial direction. The bobbin is mainly composed of a spindle and a cylindrical body, which can be used to wind yarn, and when winding the thread, the bobbin is held between the headstock and the spindle, and when the yarn winding part is wound around the bobbin, the bobbin is held between the headstock and the cylindrical body. It is characterized in that it is configured so that the bobbin and the thread are held between them, and the cylinder moves forward immediately after the rotation of the headstock stops and presses the bobbin between it and the headstock. This effect can be achieved.

■ In the conventional example, the compression spring was embedded in the spindle, and the tip of the spindle and the headstock could be attached and detached; it was necessary to form a retaining part for each, making the structure complicated. However, according to the present invention, the compression spring and the engaging portion are not required, and the structure can be simplified.

■ In the conventional example, the compression spring cannot withstand long-term use, and the entire spindle in which the compression spring is embedded is considered a consumable item, and it is replaced after a certain period of use. On the other hand, the present invention is superior in terms of durability, which has some parts that cause performance deterioration with long-term use.

■ In the conventional example, the movement of the bobbin in the rotational direction and axial direction is restrained by a compression spring, but as the performance of the compression spring deteriorates, there are cases where the bobbin cannot be restrained and supported in the above state, resulting in poor bobbin winding condition. may invite In contrast, in the present invention, since the bobbin is clamped between the headstock and the spindle, the movement of the bobbin in the rotational direction and the axis and direction can be reliably restrained, so that good thread winding work can always be performed. .

■ In the conventional example, the headstock and the tip of the spindle cannot be held together smoothly if the rotation angles and displacement positions when the two are stopped are different. There was a drawback that sometimes an impact J was applied between the two retaining parts, leading to failure of that part, but in this case, the K is not configured so that the headstock and the spindle tip are in a retaining relationship. Therefore, the above drawbacks can be corrected.

■ In addition to having the above-mentioned effects, the present invention is configured such that the cylinder of the tailstock moves forward immediately after the headstock stops and pinches the bobbin between it and the headstock. , the king of the tailstock becomes one, and they stop at the same time. In this way, in the present invention, the bobbin can be brought to a sudden stop when the headstock stops due to the negative braking action, so that when the bobbin is subsequently dropped by retracting the tailstock, the bobbin can be held quietly in a predetermined position. 1/ζ can be allowed to fall naturally, and the subsequent cutting work and thread winding work can be carried out smoothly.
