Abstract

PURPOSE:To let an interval between a ringlike running belt and a belt situated in its upper side take a gap through which even such a deformed part in a strip is made passable in an easy manner, by installing a suction device in a guide plate for the ringlike running belt at the side of a locking device, while running the strip in a way of attracting it to this belt by suction. CONSTITUTION:An air suction chamber 16 is set up at an opposite surface part of a running belt 13 in a guide plate 14 at the locked side. Now, when a strip S is inserted into a pair of running belts 6 and 13 and made to run through, the strip S is forcibly pressed by a press-down cylinder 10 and a compression spring 9. At this time, when the air suction chamber 16 is made into suction pressure by exhaust out of an exhaust port 11, air is inhaled out of a suction hole of the running belt 13 via a rectifier part 15 and a vent hole 14' of the guide plate 14, thus the strip S is attracted to the running belt 13 by suction force. According to this method, press-down force in the cylinder 10 and the spring 9 is reducible as much as a portion for suction force so that a for variation part in the strip S is as well made passable so easily.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in belt pridles for coil processing lines.

Generally, in a lysing configuration for continuous coil processing, a priddle is necessary for the lysing operation.

However, the belt pridle is said to be more effective than the 0-ru method in cases where there is a large tension change or a large difference in tension between the pridle and the front of the pridle. And, the belt pridle has independent front and rear struts without affecting front and rear tension changes.

It is possible to control the travel of the lip, and either the front or rear tension is t! It can also be operated with O tension. Further, when the strip runs, there is an advantage that there is no meandering when the strip moves from the belt priddle entrance to the belt exit.

However, the strip running belt cannot be opened to a part where the shape of the strip changes, such as a strip connection part, and it is necessary to always hold the strip.

Therefore, when passing through the strip shape changing section, the strip must be stopped running or the strip must be held in place.
The drawback is that the belt or strip is likely to be damaged if passed through.

In addition, as shown in Fig. 1, the conventional belt prydle has a fixed side consisting of a drum (1), a running belt (2), a belt tensioner (3), and a guide plate (4). , the belt hanger is a drum (5 tons) and a regular door (6), a belt tension roll (7), a guide plate (8), a guide plate push spring (
9), and is divided into a moving side that moves up and down by a pressure syringe 00. And the above running belt (2)
The guide plates (4) and (8) were configured to face each other with (6) in between.

Then, the strip 4) is passed through the running belts (2) and (6) so as to be held between them, and the strip 6 is pressurized with a pressure syringe of 00 to apply a force exceeding the tension necessary for operation.
) is generated in the direction of travel. The running belt hook controls the running of the player or t-tater (not shown) connected to the drum (1).

At this time, traveling bell) (2) (6) is a thin steel plate d><
Since the thin steel plate (i) <4) and the guide plates (4) and (8) are sliding, it is desirable that the frictional resistance is low. Therefore, the guide plates (4) and (8) are made of a material that is wear-resistant and has a small coefficient of friction against steel plates (for example, differential zero steel).

In order to operate with the belt priddle with the above configuration, the stationary side belt hanger should be installed with the dome (1) and guide plate (4) sufficiently level, and the rolling blades of the moving side rolling down syringe α1 should be set equally. At the same time, adjust the rolling edge of the push spring (9) of the guide plate (8) so that it is sufficiently equal to the width direction of the strip 0), and place the stop jf3) between the running belts (2) and (6). When the belt is passed through and runs, the rolling syringe 〇〇 and the rolling blade of the pressing spring (9) press the running belt (6) via the belt hanging drum (5) and the guide plate (8), respectively. Therefore, the strip(s) running on the belt 2)
(6) will be pressed, and frictional force will be generated on both the front and back sides of the strip 6). At this time, the frictional force between the stop jB) and the running belt (2) (6) is the same as that of the guide plate (4).
(8) and the running belt (2) (6) are also several steps larger, so the running belt (4)
(6) always follows the movement of strip β), and there is no slippage between running belt (2) (6) and strip 0).

The conventional belt pridle is operated as described above, but when the strip shape changing part such as the connection part of strip 0 passes, it ascends the rolling cylindrical cylindrical part (10) and moves between the running belts (2) and (6). It is necessary to provide an intervening part in the strip to allow the strip to pass through the shape changing part. However, if the running belts (2) and (6) are separated, the strip 6) will not be pressed, and the The reaction force against the tension is t! Becomes a mouth. Therefore, rice running control becomes difficult. Therefore, when passing through the strip shape changing section, the strip 6 stops running and allows the belt prydle to pass slowly.

Lower the pressure syringe a*'tt and return the output of the peridot valve to the operating speed of the strip (however), or
Either the syringe .alpha.Q can be passed through the strip shape changing section without being raised and pressurized. However, the former requires stopping the running of the strip 6), and the latter requires stopping the running of the running belt (2) (6) or the strip 6).
) and may cause shock to the equipment.

The present invention was developed as a result of various researches in view of the actual situation of oblique tops, and its purpose is to eliminate the drawbacks of conventional belt pridles.
At the same time, even if the rolling blade of the rolling cylindrical member is removed, there will be no stripping between the strip (However) and the fixed side running belt. In order to generate tension in the running direction, it is possible for the strip 0) to run continuously even if the rolling cylinder is raised when passing through the strip shape changing part and a gap is provided between the running belts (2) and (6). Another object of the present invention is to provide something that can prevent damage to the running belt or strip 6).

Hereinafter, the present invention will be explained based on illustrated embodiments.

Components that have the same function as the belt pridle shown in FIG. 1 are given the same numbers. Therefore, FIG. 2 shows a first embodiment of the present invention, in which an air suction chamber (lft) is installed on the opposite side of the running belt (2) of the stationary guide plate (4) illustrated in FIG. , the guide plate α→ corresponds to the guide plate (4) in FIG.

In addition, (1) is the belt hanging on the drum, (2) is the running belt, and (3) is the belt tension 0-arm which together with the p1 guide plate α, constitutes the fixed side of this belt priddle. As the moving side of the belt, the belt hook is on the drum (5).
, a running belt (6), a belt tensioner (7), a guide plate (8), and a guide plate push spring (9), and is moved up and down by a tab insulator 01.

Then, sandwich the running belts (2) and (6) and guide plate α.
4 (8) are arranged to face each other.

In addition, the guide plate α is provided with a large number of ventilation holes α, and an air suction chamber (T) is in communication with the honeycomb-shaped rectifying section (G) of the ventilation hole α4. It is provided. The air suction chamber (g) is connected and communicated with a vacuum pump (not shown) via an exhaust port αη.

Further, the running belt 0 has a large number of suction holes (6) formed on the entire annular surface as shown in FIG. 8, and are bored together with the thin steel plate (2) as shown in FIG.

Now, if the strip 6) is passed through all the above-mentioned running belts (6) and run between Q3, the strip (however) will be applied by the reduction cylinder 01 and the push spring (9), and the exhaust port aυ) Due to the exhaust gas, the air suction chamber (to) becomes negative pressure, and suction is carried out from the suction hole @ drilled in the running belt 0 via the rectifier (g) and the ventilation hole (b) of the guide plate α. The strip (however) is attracted and adsorbed by the running belt (2) and runs.

Therefore, for the necessary tension generated during the life operation of the belt priddle, the following cylinder -00 and push 1<ne(9
) to reduce the suction force of the air suction chamber (to) by the suction force of the air suction chamber (to).
Raise the moving side pressure silicitor C1O and connect the running belt (6
) (Even if a gap is provided between strips 13 and 13 for the strip to pass through the shape changing part, strip 0) runs adsorbed to the stationary side running belt (to) and generates all the tension, so it is difficult to control the running of the life. There is no change and the operation can be continued. Next, FIG. 5 shows a second embodiment of the present invention, in which the stationary side guide plate (4) opposite to the running belt (2) shown in FIG. Two electromagnets are installed on the surface so that the guide plate (4) and the running belt (2) are completely transmitted through and the strip is attracted and adsorbed onto the surface of the running belt (2). The material of the strip in this case must be a magnetic material such as a steel plate.

Further, the guide plate (4) and the running belt (2) (2) are made of non-magnetic material.

For example, the running belt (2) is made of 5US804 material.

Now, run the above running belt (2) (6)
When the strip 0) is passed through and run between the two, the strip 0) is pressurized by the pressure syringe and the push spring (9), and the guide plate (4) and the running belt (2) are moved by the electromagnet αη. Since the strip G) is absorbed through the transmission, the strip G) is attracted to the surface of the running belt (2) and runs.

Therefore, for the tension required during the life operation of the belt priddle, the retainer syringe αO and the push spring (9)
It is possible to reduce the total pulling force of the electromagnet αη, and when the strip passes through the shape changing part, the voltage of the electromagnet ση is increased to increase the attraction force of the electromagnet αη,
Raise the moving side pressure syringe and turn the traveling bell l-(2
) Even if a gap is provided between (6) for the strip to pass through the changing part, the strip 6) runs adsorbed to the stationary side running belt (2) and generates tension, so there is no change in the life running control. There is no such thing and it can be operated.

As described above, the present invention provides a belt priddle with a coil processing life divided into a movably bound Machida device side and a fixed device side, in which a suction device is provided on the guide plate of the annular running belt on the fixed device side. This is a suction-type belt prydle that is characterized by a structure in which the strip running on the belt is adsorbed by the above-mentioned suction device to the annular traveling belt on the fixed device side and runs, so it loses the advantages of the conventional belt prydle. When the strip shape changing section passes through, a gap is provided between the belts so that the strip shape changing section can be passed through without damaging the belt or the strip (t). It is a variation on the current roller pridle, and allows it to be installed at any position in the life.
