JPS5917447A - Winder for bridle roll - Google Patents

Abstract

PURPOSE:To make a plate-through process so as to be achievable in a smooth manner, by installing a device capable of automatically winding the tip of a strip around a bridle roll in regular sequence, which feeds the strip with tension added, in case of processing the large work of a metal and/or a nonmetal. CONSTITUTION:Fitting strips 15a, 15b and 15c holding the tip of a strip 3 are interposingly installed free of advance of retreat in a triple of swivel arms 17a, 17b and 17c rotatably pivoted on a roll shaft 14 in cooperation with the roll surface, respectively. When the tip of the strip 3 is held by these fitting strips 15a-15c, these swivel arms 17a-17c are all rotated together with rolls 1a, 1b and 1c. On the other hand, when no strip 3 is held, these swivel arms 17a-17c are rotated in the reverse direction of rotation to these rolls 1a-1c by means of a swivel arm reset device 24 installed in each of swivel arms 17a-17c. Therefore, at each of these rolls 1a-1c, the tip of the strip 3 is held in turn by the roll surface and each of fitting strips 15a-15c so that the strip 3 can be wound around all rolls 1a-1c in regular sequence.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a bridle roll (tension 1 (11 This invention relates to a bridle roll winding device that can sequentially wind the leading end of a strip onto each roll.

BACKGROUND ART Conventionally, in the manufacturing process of metal and non-metallic strips and ropes, bridle rolls, which are roll devices for continuously feeding strips and ropes, have been used. The flight roll here is, for example, 3 as shown in Figure 1.
It consists of two wheels la, Ib, lc and snubber rolls 2a, 2b which are provided as needed and are movable up and down. The stripped strip 3 is subjected to tension or absorption suitable for the next process, such as glossing.

In such a bridle roll 4, the strip 3 entering onto the roll la is passed through the three rails 1a,
1b. When stretching the IC, it is necessary to bend or follow the curved surface of each roll.

For this purpose, arcuate guides 5a, 5b, 5c are provided at necessary intervals on the outer periphery of each roll 1a, 1b, 1c with a constant strip passing gap, and these guides guide and guide the thin strip 3. Alternatively, as shown in FIG. 2, a grid 6 is provided in each guide 5a, 5b, 5c, and a rod (not shown) is inserted from outside the guide F, and the end of the strip 3 that has entered is It is wrapped along the curved surfaces of the rolls la, 1b, and 1c by pressing down the parts.

However, if the strip is thick, it is difficult to bend it along the guide without applying any force to the incoming strip, and it is also difficult to bend the strip along the guide without applying any force to the strip. The strip must be bent and guided by inserting a hand or a rod through the grid of the guide.

In such cases, winding the wire in different directions in a narrow machine inevitably requires manpower and labor, and is often dangerous depending on the environment and location.

Of course, a bridle device (utility model patent No. 101) that passes the strip linearly by changing the positional relationship of the rolls
8442), but it has the disadvantage that the space and mechanism are very large. Also, there are other mechanisms [
・If the lip is particularly thick, it is difficult to align it with the roll radius by hand, requiring various tools, and it is difficult to roll the strip smoothly1'.Furthermore, it may cause scratches on the roll surface. many. On the other hand, if the strip is thin, it will break in the gap between the guy 1 provided between each roll and the roll, resulting in a disadvantage that more scraps will be generated.

Additionally, the strip ends are usually not in good shape and often do not maintain a shape that allows for smooth rolling. All of these things result in a loss of labor and time, causing a reduction in production efficiency.

The present invention was made in order to solve the above-mentioned problems, and even if the shape of the strip is bad, it is possible to hold the tip of the strip on the roll without requiring direct human power, making it extremely easy to wind the roll. It is an object of the present invention to provide a winding device for a priddle roll.

The feature is that a pair of swinging arms rotatably supported on the roll shaft are interposed with a sandwich plate that cooperates with the roll surface to hold the tip of the strip so that it can move forward and backward in the radial direction of the roll. , a swing arm return means is attached to each swing arm for rotating the swing arm together with the roll when the strip end is held, and for rotating the swing arm in the opposite direction to the rotational direction of the roll when the strip end is not held. This is a priddle roll winding device that can sequentially hold the tip of the strip between the roll surface and the sandwich plate on each roll and wind the strip around all the rolls.

Hereinafter, the present invention will be explained based on drawings showing embodiments thereof.

The rolls la, lb, and lc are supported by bearings 11 on a frame 10 shown in FIG. As shown in FIG. 3, a sandwiching plate 15 (15a) is provided on the outer periphery of the roll 1a immediately after the snubber roll 2a used for feeding the strip 3, and this is provided with a sandwiching plate 15 (15a) that is attached to the roll l in the longitudinal direction of the roll l. A guide 16 (16a) is attached to guide the entry of the tip of the strip 3.

This clamping handle 15 is mounted so as to be movable in the radial direction of the roll 1 within each long groove 18 of a pair of swing arms 17a, 17b, and 17c mounted on both sides of each roll. As shown in the figure, it is rotatably supported on the roll shaft 14 by a bearing 19.

A bracket 20 is fixed to a part of the swing arm 17.
A power #i21 is attached to the air cylinder 4y, so that the plate 7j can move forward and backward in the long groove 18 mentioned above.

Furthermore, the lever 23 shown in FIG.
is integrated, and this lever 23 is operated by a lever driving source 28 supplied with air through a pressure regulating valve 25, which is a swing arm return means 24, a direction switching valve 2, and a speed control I/roll valve 27. It is configured to be rotated as necessary in the direction B, which is opposite to the input direction, which is the forward rotation of. This lever 23 attaches to the roll la and rotates when the tip of the strip 3, which will be described later, is clamped together with the clamping plate 15, and at the end position of the rotation in the A direction, a proximity sensing switch is installed. When it comes into contact with the stopper 29, further rotation is restricted. Note that the other rolls 1b and 1c are also provided with 61M rotation arms 17b and 17c having similarly configured clamping plates 15b and 15c, but the rotation angle is large like the rotation arm 17b of the roll 1b. In such a case, it is preferable to configure the rotating drive source 30 and a set of gears 31 to rotate as shown in FIGS. 3 and 5.

Since the present invention is configured as described above, it can be operated as follows.

In FIGS. 3 and 4, the strip 3 that has arrived at the upper surface of the roll 1a is first pressed down by the snare-sohar roll 2a. When the roll 1a is rotated by the drive source 13a, the strip 3 comes to the position of the sandwich plate 15a. Then, the power source 21 is activated to draw the clamping plate 15a toward the roll 1a, thereby pinching the tip of the strip 3. At this time, the swing arm return means 24, which is a compressed air circuit configured as shown in FIG.
The roller 7a rotates together with the roll 1a in the forward rotation direction, rotates by α degree as shown in FIG. 6, and comes into contact with the stopper 29b.

At this time, the proximity sensing switch built into the stopper 29b is actuated by the swing arm 17a, and the power source 21 moves the pinch plate 15a away from the roll la and releases the stopper 3. The roll 1a continues to rotate in the incoming direction, but the swing arm 17a is stopped at the collar 29b.

The strip 3 is sent out sequentially by the roll 1a and the snubber roll 2a, and as shown in FIG.
) 6 b
When the tip enters the roll 1a side, the sandwiching plate 15b
is operated in the same manner as in the previous case, and the roller 1b is pinched between the rolls 1b and 1b. At this time, if the set of gears 31 is not in a restrained state, the swing arm 17b rotates together with the roll lb to the stopper 29d, and the strip 3 is wound around the roll 1b. During this time, the swing arm +7a of the roll 1a is rotated by the direction switching valve 26 and the lever driving source 28 in the direction B, which is opposite to the forward rotation direction of the roll 1a, and comes into contact with the stopper 29a as shown in FIG. will be returned to the position. It should be noted that the stopper 29a also has a built-in proximity detection switch, which outputs a signal to put the swing arm return means 24 in the escape state, and performs the above-mentioned operation when the tip of another strip approaches. is now possible.

The transfer of the leading end of the strip 3 from the roll 1b to the roll 1c and the rotation of the swing arm 17c are carried out in the same manner as described above, so a description thereof will be omitted. Note that the swing arm +7b is returned to its original position by the drive source 30 with the gear 31 in a restrained state.

The above-mentioned swing arm 17 is rotatable at the center of the roll axis 14 of each roll, so that the imbalance of inertia, which is the most problematic problem with this type of D-roll, can be avoided. Even during passing operation, the pincher can be easily returned to its original position after operation without any hindrance.

As described in detail above, the present invention has a pair of rotating arms rotatably supported on a roll shaft, and a pair of rotating arms that move back and forth in the radial direction of the roll to hold the tip of the strip in cooperation with the roll surface. Return of the swinging arm, which is freely interposed and rotates the swinging arm together with the roll when the slip end is held, and rotates in the opposite direction to the rotational direction of the roll when the slip end is not held. Means are attached to each pivot arm, so that the leading edge of the strip can be held in sequence on each roll between its roll surface and the pinch plate, and the strip can be wound around all the rolls.

Therefore, the tip of the strip can be wrapped around the bridle roll very easily and automatically, and threading can be smoothly performed.
