Abstract

PURPOSE:To correct the twisting of a cylindrical bag body simply by expanding and holding a part of a proceeding soft cylindrical bag body and detecting the twisting of the cylindrical bag body in the front of the holding part for rotating the cylindrical bag body of the holding part reversely to the detected twisting. CONSTITUTION:A soft cylindrical bag body, for example, a fire hose 18 is at first pushed into an introduction port 44, shaped to be oblong through guide rollers 41 and 40, and sent to a suction roller 27. Then, a penetration hole 15 is closed by a lid 17, and pressures inside a concave groove 3 of a casing 2, a pressure-reduction chamber 21, and a suction pipe 29, are respectively reduced by the suction work for absorbing the hose 18 to a rotor 37. Subsequently, the hose 18 is sent into a cylinder body 47, and the penetration hole 15 is opened to reduce the pressure in a hollow part between an inner wall 14 and the hose 18. After the hose 18 is expanded and a rod 19 is made to bite into the peripheral face, the hose 18 is rotated together with a rotary drum 4. When a colored line on the hose 18 is slided as it passes through a twist-detecting device 45, the rotary drum 4 is rotated reversely to the detected twisting for correcting the twisting.

The outer diameter of 8 is equal to y or slightly smaller than 7n (C is larger than cylindrical body 47 with a through hole 46 in its upper part, and the through hole 4
The hose 18 is pushed through the cylindrical body 4'19, and the through hole 46
The photoelectric tubes 48 and 49 are designed to detect the screw n of the hose 18 by detecting the position of the colored line of the hose 18 by capturing the reflected light from the light emitted from the hose 18 and the photoelectric tubes 48 and 49. The motor 28 is rotated by the 16g emitted from the 1i48.49, the rotating drum is rotated forward, reversed, or stopped, and the screw n of the hose 18 is corrected so that the color line of the hose 18 is always aligned at the position 111 of the through hole 46. It's just like that.

50 is a pulling device that folds and stores the hose 18, and 51 is a winding machine that winds the hose 18 that has been taken out. This device is used to straighten the threads of the hose 18. for,
First, the hose 18 is pushed into the hose inlet 44 from one end thereof. The tip of the hose 18 passes through the hose inlet 44, then between the rollers 48 and 48 of the guide roller 41, and then between the rollers 42 and 42 of the guide roller 40.
It passes through the 10\Ifj4 long shape 9, the kite ring 89, and then the rotor 87 of the suction roller 27.
Enters 87 spaces. At this point, when the through hole 15 is closed with k17 and suction is performed from the suction pipe 207Oh with a vacuum bomb (not shown), the inside of the groove 8 of the casing 2 is under pressure.
The pressure inside the decompression chamber 21 is reduced through the through hole 6. Then, the pressure inside the suction tube 29 is reduced through the YC connecting vibe 81, and air is sucked through the long hole 85η of the rotor 370 through the n1 long hole 88, and the hose 18 is adsorbed onto the rotor 87.

In this state, the rotor is 87 with air 7-tar (without blowing)
When rotated, the hose 18 line is sent forward through the n1 guide ring 88 to the rotor 86.8 of the suction roller 26.
Enter the 6th review. Here, similarly to the suction roller 27, the rotors 86, 86 rotate while sucking the hose 18, and send the hose 18 forward. Hose 18ri moves forward,
The leading end passes through the center of the rotating drum 4 and enters the cylindrical body 47. Here, the lid 17 of the rotating drum 4 has a through hole 15.
When opened, the dark space between the inner wall 14 and the hose 18 is depressurized, and the hose 18Lri is inflated, its outer circumference + tK extension 1.
9 bites in, and the hose 18 is firmly held in a round, swollen state. When the motor 23 is driven to rotate the rotary drum 4, the hose held there also rotates together with the rotary drum 4. If the color line of the hose 18 is at the position of the through hole 46 of the cylinder body 47 *If-, then the photocell 48.4
9 senses this, the motor 23 is stopped, and the rotation of the n1 rotating drum 4 is stopped. At this position, the hose moves further forward and the tip is pulled! When 50 VCN is loaded in the 9th tank, the air motor stops and the drive of the rotors 86 and 87 stops.

Next, pull! ! The take-up device 50 is driven and the n1 hose 18 is taken out and wound around the n1 winding V fold.

At this time, the hose 18 is pulled by the pulling device 50 and scraped, and the rotor 86, 87 rotates while the suction rollers 26, 27 suck the hose 18 and adjust the shape. When the position of the colored line of the hose 18 passing through the screw n detection @@46 is incorrect, the phototube 48, 49 senses it and drives the motor 28, and (b) rotates the rotary drum 4. screw f
The L is rotated 191 times in the opposite direction, and when the color is in the correct position, the photoelectric sensor senses it again and stops the rotating drum 40 rotations. Therefore, hose 18
The colored line passes through the hole 46 of the cylinder 47, and is then folded flat with the drawer 50 and taken out, and then wound into the take-up device 51. n, so
Volume 1! This allows you to position the colored line in the center of the hose you took.

The present invention is to move a flexible cylindrical body such as a fire hose 18 along its length while sucking air from the outer periphery of the ml-shaped bag at a part of the body.
What is the screw n that is detected in the circumferential direction of the cylindrical bag of the holding part by detecting the presence or absence of the screw n of the cylindrical bag in front of the holding part and using the gs signal issued by the detection? By rotating the screw in the opposite direction, the screw n is straightened, and since it is inflated into a round shape and twisting is detected and straightened in good condition, the cylindrical bag is not damaged and the straightening is easy. And it can be done reliably. Furthermore, since the cylindrical bag is inflated by suction from the outer periphery, there is no need to insert the main body into the bag, and a long cylindrical bag can be used for one time.

Moreover, in [11] of the present invention, before the cylindrical bag is fed to the rotating drum, it is passed between suction rollers and suction is applied from the outer periphery, so that the cylindrical bag is inflated and shaped. The cylindrical bag can be supplied to the rotating drum in a stable state, and the cylindrical bag will not wrinkle or deform. In addition, the rotating drum 4-wire cylindrical bag can be opened by suctioning from the outer periphery to make it round, and the 4-wire cylindrical bag can be reliably held at 4 degrees because of the protrusions provided on the circumference. However, screw wear can be corrected by rotating the screw IK, and L5 will not idle due to only the rotating drum. Also, in the embodiment, two sets of suction rows Y-26V27
A guide roller 40.
41 and guide links 88 and 89, the cylindrical bag can be held securely by these as well.
As the rotary drum 4 rotates, the rear cylindrical bag can also be rotated at the same time, making it possible to straighten the screw n. Also, suction roller 26.27t
- By rotating it with an air motor etc., it becomes easy to feed the cylindrical bag to the rotating device l,
Work becomes easier. Also in a real example! 17 is a cylindrical bag 'fr.Since the inner periphery of the rotating drum 4 is open when it is first supplied, the through hole 16 of the partition wall 18 is closed with a lid 17 to suck air from the circumference of the rotating drum 4. to prevent
It functions to increase the suction force of the suction roller 26$27.
