Description

[Detailed explanation of the idea] The present invention relates to a drawing device for reeling yarn.

Conventionally, a rotary plate that rotates at a constant rotational speed is provided with a roller at an eccentric position, and a swingable L-shaped arm supported by another shaft provided above the shaft of the rotary plate is provided, and a shaft is attached to one end of the iron arm. The supporting cam plate is connected to the retrieval pawl of a fineness sensing device provided on the running yarn portion through a rod at the other end, so that the retrieval pawl performs a retrieval movement in conjunction with the rotation of the rotary plate. Things are known.

However, in such a device, the search drive unit and the picture activation unit are provided separately.

Not only is a communication means needed to communicate between the search drive unit and the picture activation unit, but also repair work must be performed for each, which is troublesome and takes up a lot of space.

The purpose of the present invention is to obtain a picture starting device that does not have such inconveniences.The purpose of this invention is to provide a roller at an eccentric position of a rotary plate that rotates at a constant rotation speed, and to attach a roller to another shaft provided above the shaft of the rotary plate. Search for a fineness sensing device that has an L-shaped arm that is supported and swings freely, a cam plate that is pivotally supported on one end of the iron arm, and a rod that is connected to the other end of the iron arm and installed on the running yarn section. A painting arm is connected to the pawl so that the retrieval pawl can perform a retrieval movement in conjunction with the rotation of the rotary plate, and the painting arm is pivotally supported in the middle on the machine frame so as to be able to swing freely. one end of the picture arm faces the lower surface of a cam plate which rotates integrally with the rotating plate provided on the axis of the rotary plate, and a spring is provided for pressing the end of the swinging arm against the cam plate. At the same time, the cam and the arm are provided to be swingable over a certain range by engagement with a pin and a notch, and the other end of the cam is engaged with an engaging element provided on the picture arm, and this is connected to the spring. A stopper is provided to resist and keep the swinging arm in a state separated from its tip.

The present device will be explained below with reference to the drawings.

In the drawing, 1 indicates a welding device, 2 and 3 indicate rollers, and the yarn a pulled up through the welding device 1 forms a kennel between rollers 2 and 3, and is given a Vi edge and then has a slit fineness. It passes through a sensor 4, a twilling rod 5, and is wound onto a small frame 6.

Reference numeral 7 indicates a welding instruction pin provided on the slit fineness sensor 4; 8 indicates a search claw for searching for the welding instruction pin; the search claw 8 is connected to the painting operating mechanism 10 via a rod 9;
When the search claw 8 searches for the welding instruction pin 7, the painting action mechanism 10 operates to give the painting spoon 11 a painting action.

This picture operating mechanism 10 includes a picture arm 14 which is pivotably supported on a machine frame 12 by a shaft 13 in the middle.

A shaft 15 provided on the upper part of one end of the picture arm 14 and driven by an external drive source, a cam plate 16 integrated with the shaft 15, and a spring 17 that presses the picture arm 14 against the cam plate 16. An L-shaped arm whose intermediate bent portion is supported by a roller 19 provided at an eccentric position of the rotating plate 18 provided on the rotating shaft 15, and a shaft 20 provided above and parallel to the rotating shaft 15. 21
and a semicircular arc-shaped cam 2 pivotally supported on one end of the iron arm 21.
2, and a limiting rod 23 whose upper end is pivotally supported on the other end of the cam 22.
and a stopper 25 on the limiting rod 23 that locks a locking piece 24 integrated with the picture arm 14, and the other end of the arm 21 is connected to the search claw 8 via the rod 9.

When the semi-circular cam 22 comes into contact with the roller 19, the side opposite to the connecting side of the arm 21 is configured to be heavier and hollow, and there is also a cutout hole 27 that engages with a pin 26 protruding from the arm 21.
The pin 26 and the upper edge of the notch hole 27 are normally engaged so that the axial fulcrum of the arm 21 and the cam 22 and the axial fulcrum of the limiting rod 23 overlap with each other.

In addition, a long groove 23a is provided at the bottom of the restriction rod 23 along its length.
The long groove 23a is engaged with the shaft 13 to perform a certain regulated movement.

Reference numeral 28 indicates a roller provided at the end of the arm 14 opposite to the cam 16.

Next, the operation of this device will be explained.

When the shaft 15 is actively driven by an external drive device (not shown), the cam plate 22 is pushed up by the roller 19 that rotates together with the shaft 15.

At this time, in the normal reeling state, the cam plate 22 is connected to the arm 21.
Since the side on which the limiting rod 23 is provided is heavier than the connecting discharge, the cam plate 22 swings about the axis of the arm 21 due to the engagement between the pin 26 and the upper edge of the notch hole 27, i.e., the axis of the limiting rod 23. Swinging around the fulcrum is applied.

Therefore, the limiting rod 23 does not move even when the cam plate 22 swings, and only the search claw 8 continues searching for the welding instruction pin I due to the swing of the picture arm 14--arm 21.

However, when the fineness of the reeling yarn becomes thinner and the search instruction pin 7 enters the locus of the search claw 8, the swing of the search claw 8 is prevented, and accordingly, the swing of the L-shaped arm 21 is also prevented. As a result, the cam plate 22 swings about the pivot between it and the arm 21.

Therefore, the limiting rod 23 connected to the other end of the cam plate 22 is pulled up, and the engagement between the locking piece 24 and the stopper 25 is released.

Therefore, one end of the painting arm 14 faces within the rotation locus of the cam plate 16, and as the cam plate 16 rotates, the painting spoon 11 swings.

In this way, according to the present invention, a roller is provided at an eccentric position of a rotary plate that rotates at a constant rotation speed, and an L-shaped arm that is swingable by being supported by a shaft provided at the top of the shaft is provided, and one end of the iron arm is provided with a roller. A cam plate is rotatably supported on the arm, and the other end of the iron arm is connected via a rod to a retrieval claw of a fineness sensing device provided in the running thread section, so that the retrieval claw makes a retrieval movement in conjunction with the rotation of the rotary plate. In a device designed to perform this, a painting arm is provided on one machine frame, the middle of which is pivotably supported to move the painting spoon, one end of the painting arm is placed on the axis, and the A spring is provided that faces the lower surface of the cam plate that rotates together, and presses the end of the swinging arm against the cam plate, and the cam and the arm are caused to swing over a certain range by engagement with a pin and a notch. The cam is movable, and the other end of the cam is provided with a stopper that engages with the engaging element provided on the picture arm and keeps it in a state away from the tip of the swinging arm against the spring. The activation part and the picture activation part can be put together in one place, eliminating the inconvenience caused by separating them as seen in the conventional example.

In particular, it engages with the engaging element provided on the picture arm and is pivoted to one end of the cam plate, which is a stopper and keeps it in a state away from the tip of the swinging arm against the spring, so it is L-shaped. The movement of the arm directly affects the disengagement of the engager, making it possible to quickly and reliably perform painting operations.Furthermore, since the painting arm is pressed against the cam plate by a spring, it is possible to quickly and accurately perform the painting operation on one side. Even if the movement of the painting arm is obstructed by congestion, etc., there is an effect that the painting arm will not be strained.
