Description

[Detailed Description of the Invention] The present invention relates to a cloth feed roller used in a cloth vapor treatment apparatus and the like.

As shown in FIG. 4, the cloth vapor treatment apparatus 1 has a large number of feed rollers 5 placed in a steam chamber 14 at regular intervals on an endless rotating cheno 20, and transfers the rollers 5 while rotating to transfer the cloth. The cloth 4 is hung in a loop from the feed roller 12 at the entrance to the feed roller 5 and transferred together with the roller 5 for steaming, and at the exit, the cloth 4 is hung on the draw roller 13 and pulled up.

A large number of metal spikes are installed on the outer periphery of the metal tube in the feed roller 5 to prevent the cloth 4 from sliding down. However, when a heavy cloth with a fluffy surface such as a blanket is used, the spikes control the surface of the cloth. If the fabric is too thin, the loops of the fabric may become long enough to touch the steam chamber floor or the feed roller below, causing tangles.Also, if the fabric is thin, the spikes will pierce it and open the weave. So-called pin scratches occur.

Furthermore, once the spikes are stuck into the fabric, they are difficult to remove, causing the fabric to be pulled and torn between the pull-out roller 13 and the feed roller 5, and rollers with spikes embedded must be handled with care when installed inside the device. However, if the roller is accidentally brought into contact with a hard surface during transportation or operation, the spike tip can easily bend.

If you use a roller with a curved spike tip to hang the cloth, the effect of hooking the cloth will be weak and there is a risk of the cloth slipping off.
The entire book roller has to be replaced, which is expensive.
Moreover, the replacement work was difficult in the narrow steam room.

In addition, instead of the metal spikes mentioned above, as shown in Japanese Utility Model Publication No. 34-6295 or Japanese Patent Publication No. 45-25876, a group of flexible fiber protrusions may be implanted in the roll to prevent the fabric from slipping. Some have done so.

However, in all cases, the fiber protrusions are planted so that they are tilted in one direction relative to the rotation direction of the roll, so they tend to dig into the fabric, but they do not easily separate from the fabric, and there is a risk that the fabric may be wrapped around the roll. There was that.

In view of the above-mentioned circumstances, the present invention involves cutting and removing the loop ends of the hook-and-loop fastener wound around a roll to form a pair of short needle-like protrusions, which are adjacent to each other in a plane substantially perpendicular to the axis of the roll. Half of the rolls are tilted in the rotational direction of the roll, and the other half are tilted in the opposite direction to the rotational direction.

With the above-mentioned configuration, the roller of the present invention can reliably prevent the fabric from slipping due to the protrusions tilted in the direction of rotation, and since the weight of the fabric is supported by both protrusions oriented in different directions, the weight of the fabric acting on each protrusion is reduced. damage to the protrusions or the cloth caused by the protrusions is prevented, and furthermore, the protrusions tilted in the opposite direction to the direction of rotation do not bite into the cloth.
To provide a cloth feeding roller which is more efficient than the conventional example in which all the protrusions are oriented in the rotational direction, and which can solve the above-mentioned problems at once, such as eliminating the risk of the cloth getting caught in the roll.

The present invention will be specifically explained below based on embodiments shown in the drawings.

The multi-feed rerollers 5 are rotatably mounted at equal intervals on a rotating chain 20 disposed in a known vaporization processing apparatus 1 shown in FIG. The cloth 4 hung on the wall is sent from the population 10 side to the exit 11 side.

As shown in FIG. 1, the cloth feed roller 5 has a hollow cylindrical roll 51 made of a corrosion-resistant metal such as stainless steel, and a shaft 52 for attaching a Cheno sprocket 23 (to be described later) protruding from both ends, and a heat-resistant roller 52 is provided on the surface of the tube 51. A hanging surface is formed by protruding a large number of needle-like protrusions 53 made of flexible hard synthetic resin.

The needle-shaped protrusions adjacent to each other in a plane substantially perpendicular to the axis of the roll 51 are inclined alternately in the rotational direction of the roll and in the opposite direction to the rotational direction.

The hanging surface is the loop 62 of the hook-and-loop fastener 6 shown in FIG.
It can be formed by cutting.

The hook-and-loop fastener 6 is made of a heat-resistant flexible hard synthetic resin, and is made of a belt-like material in which 35 loops 62 are planted per 1 cm2 on one side of a sheet 61, and the tips of the loops 62 are cut to have a length of approximately 0. A needle-like protrusion 53 of .8 mm is formed.

Since two protrusions 53 are formed from one loop, 70 protrusions 53 protrude per 1 cm 2 on the sheet 61.

If the sheet 61 is wound spirally around the outer periphery of the cylindrical roll 51 with the protrusion surface facing up, a multi-feed reroller 5 having high-density needle-like protrusions 53 on the surface is completed.

To explain in detail the vaporization processing apparatus 1 equipped with the double feed reroller 5, as shown in FIG.
An outlet 11 is opened on the other side, and the cloth 4 that has undergone the dyeing process is opened at the inlet 1.
The cloth 4 is heated while it passes through the steam chamber 14, which is drawn in through the opening 0 and pulled out through the outlet 11, and filled in the steam chamber 14.

In the upper part of the steam chamber 14, a feeding roller 12 and a drawing roller 13 having a large number of flexible needle-like protrusions on the outer peripheral surface, similar to the feeding roller 5, are provided on the inlet 10 and outlet 11 sides, respectively. Sprockets 21 and 21 are provided at the front and rear corners of the steam chamber 14 below the rollers 12 and 13, and an endlessly rotating chino 20 is stretched between the sprockets 21.

The upper outlet side sprocket) 21a is fixed to the drive shaft 28 and rotates integrally with the drive shaft 28, as shown in FIG.
The other sprockets are rotatably supported on the chamber wall and guide the movement of the revolving chino 20.

The end portions of a large number of feed rollers 5 are rotatably fixed at equal intervals over the entire length between both sides and the circumferential chains 20, 20.

Also, sprocket 2 is attached to the upper sprocket 21.21a.
4 are arranged in parallel to freely rotate, and the sprocket) 24. A rotating chino 25 is stretched endlessly between 24, and the drive shaft 28
A transmission mechanism 26 connects the freely rotatable sprocket 24 and rotates the two sprockets 21a and 24 in opposite directions, so that the rotating chain 25 is connected to the orbiting chain 20.
is moving in the opposite direction.

The rotating chino 25 is attached to the shaft 52 at both ends of the feed roller 5.
The feed rollers 5 are each provided with a sprocket 23 that engages with the cloth.Thus, the feed rollers 5 are supported by the revolving chino 20 and rotated in the cloth feeding direction by engagement with the rotating chino 25.

A brake motor 22 with a clutch is connected to the end of the drive shaft 28 via a transmission means 29, and a cam ring 16 having a cam surface formed at the pitch angle of the feed roller 5 is attached to the shaft of the upper sprocket on the inlet side. Deploy and limit switch LS
1-pitch movement of the feed roller 5 is detected by I.

The feeding roller 12 and the drawing roller 13 rotate at a constant speed, and a rotation speed counting device (not shown) is provided at the end of the feeding roller shaft to measure the length of the cloth fed out by the rotation of the rollers. The clutch-equipped brake motor 22 is actuated every predetermined rotation of the feed roller 12 to move the rotating chain 20, and the limit switch LSI is pressed every time the feed roller 5 moves one pitch to stop the motor 22. be.

The cloth 4 is thus continuously drawn into the steam chamber 14 by the uniform rotation of the feed roller 12.

The transition occurs intermittently in response to the rotation of the feeding roller 12.

Feed 4 <va+- When the roller 5a passes below the feed roller 12 and stops, the cloth 4 hanging down from the feed spout 12 comes into contact with the surface of the feed roller 5a.

Seventy needle-like protrusions 53 per cnn2 protrude from the outer periphery of the feed roller 5a, and since the protrusions 53 are flexible, they do not penetrate the cloth 4 but are hooked by frictional force. It can stop the cloth from sliding down.

Therefore, the cloth 4 that is continuously fed by the feeding roller 12 hangs down toward the succeeding feeding roller 5b, and as the roller 5b moves, it hangs in a loop between the rollers 5a and 5b and is vaporized.

When the feed roller 5 approaches the drive shaft 28, the cloth 4 is pulled up by the pull-out roller 13, exits from the opening of the outlet 11, and is sent to the next process.

The flexible needle-like protrusions 53 on the surfaces of the pull-out roller 13 and the feeding roller 5 do not penetrate the fabric, but the bending elasticity of the protrusions 53 prevents the fabric from slipping off.
When pulled up by the pull-out roller 13, the roller 13
The cloth will not be pulled or torn between the roller and the feed roller 5.

As described above, among the protrusions 53 and 53 that are adjacent to each other in a plane substantially perpendicular to the axis of the roll 51, one of the protrusions is inclined in the direction of rotation of the roll 51, so that it pulls the fabric with a large frictional force. Hang it to ensure that the cloth does not slip off.

In addition, since the weight of the fabric is supported by both protrusions 53 and 53 having different inclination directions, including the protrusion 53 that is inclined to the opposite side to the rotation direction,
The weight of the fabric acting on each protrusion is reduced, and damage to the protrusion itself or the fabric caused by the protrusion can be prevented.

In addition, half of the protrusions are tilted in the opposite direction to the rotation direction of the roller, so they do not dig into the fabric, so they are more effective than conventional products in which all protrusions face the rotation direction of the roller. Therefore, there is no risk of the cloth getting caught in the roller.

In addition, since the protrusions 53 are flexible, even if the weight of the cloth acts on them, the protrusions 53 are only elastically bent and are less likely to be damaged, so that they can withstand long-term use.

Furthermore, the feed roller 5 can be formed by cutting the tip of the loop 62 of the hook-and-loop fastener 6 and winding it around the cylindrical roll 51.
Compared to conventional methods in which metal spikes are implanted in pipes, this method has many superior effects such as being extremely easy to manufacture and inexpensive.
