Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, there is provided a supply unit (10) for feeding the tube member (1) wound on the bobbin (11) in the shape of a band with a guide of the guide roller (12): and a tube member (1) conveyed from the supply unit (10). A joining portion for joining the joints 21 which are joined together along the longitudinal direction of the tube member 1, which is elevated in a cylindrical shape and is wound up to the position of the slit 23 opened in the through-hole 23 of (22) ( 20) and: the belt 35 is rotated by the driving of the pulley 32 is rotated by the motor 31, the tube member 1 and the belt 35 is in close contact with the outside by the guide rollers (34) A transfer unit 30 for carrying out the transfer; The cylinders 53 and 54 are operated at a predetermined cutting position detected by the sensing means 40 which detects the length of the cut portion of the tube member 1 and transmits a signal thereof to deceive the cut-in 51 and 52. It is configured to be provided with a cutting portion 50 for cutting the hollow tube member (1).

Tube member (1) to be applied to the present invention is applied to the superposition coating of polyetchene in multiple layers on both sides of the thin plate-like aluminum thin plate as a harmless material excellent in flexibility and waterproofness and corrosion resistance.

The supply unit 10 is a process unit for continuously supplying the tube member 1 in the shape of a band.

This tube member 1 is supplied to the guide of several guide rollers 12 in the state wound on the bobbin 11 with the width which can obtain the tube container of a desired diameter in the state wound in a cylindrical shape.

The joint part 20 is a process part for forming a tube by joining the outer circumferential surface thereof in a longitudinal direction while the tube member 1 is wound in a cylindrical shape.

The joining portion 20 is formed by a holder 22 for forming the tube member 1 into a cylindrical shape, and a joining tool 21 which is elevated to a position of the slit 25 opened to the holder 22.

The holder 22 is provided with a through hole 23 for passing the tube member 1 in a state wound in a cylindrical shape, and the joining tool (Slit 25) is opened at the position of the slit 25 opened from the through hole 23. 21) is to be moved up and down and to join the joints of the tube member (1).

At this time, the method of joining the joints of the tube member 1 is a method of thermal bonding in which the thermal bonding is performed by the heating of the heater wire, and the tool horn is vibrated by the ultrasonic vibrator to generate heat so that the bonding is performed. In this case, bonding by high frequency or low frequency is possible, but considering the equipment cost and maintenance cost and the degree to which the bonded state is good, it has been found that the bonding by ultrasonic is most preferable.

Therefore, when the joint part 20 is an ultrasonic method, the joining tool 21 transmits that vibration is formed from the ultrasonic vibrator, so that the joint is made. In this case, a tube member is provided inside the holder 22. In order to maintain the cylindrical shape (1) at all times and to maintain the pressing force in the state where the joining tool 21 is in close contact, the cylindrical guider 24 is preferably provided.

The guider 24 is rod-shaped in the shape of a circular cross section and extends from the end of the supply section 10 to the position of the transfer section 30 through the holder 22 of the junction section 20. The flat belt-shaped tube member 1 supplied from the supply portion 10 is folded into a gentle arc shape by being in contact with the tip bottom portion of the guider 24 and gradually transported in a circular shape.

Therefore, the progress is made in the shape of a tube wound around the outer circumferential surface of the rod-shaped guider 24, wherein the tube member 1 is extended in the longitudinal direction by having a width longer than the circumference of the guider 24. The material is transported with the joints overlapped.

Accordingly, when the joining tool 21 of the joining part 20 is joined in the lowered state, the soft tube member 1 is deformed in the pressing direction or prevented from joining normally. You can do it.

The conveying part 30 is a structural part for uniformly conveying at a predetermined desired speed after joining the joint part of the tube member 1 at the joint part 20.

The configuration of the transfer section 30 is to change the rotational direction of the speed controllable motor 31 to a speed reducer (not shown) so that the belt 35 is coupled and driven between the pulleys 32 that rotate. It is made by the guide roller 34 is installed on both sides so that the accurate conveyance without slipping in the state in close contact with the outer circumferential surface of the tube member 1 that proceeds in a tubular shape.

The guide roller 34 allows the belt 35 to pass in the direction of the tube member 1 in a state in which the unit rollers are extended in the conveying direction at a predetermined desired speed by adjusting the width in the pressing direction. The guide roller 34 is screwed to the screw 37, and the screw 37 is operated in a forward and reverse direction at a desired time by the stepping motor 36. It is good to be able to adjust the driving time and the pressure so that the belt 35 is in close contact with the tube member (1).

And, it is preferable to install the conveyor 38 to maintain the exact speed without falling even on the bottom surface in the direction in which the tube member 1 is conveyed, so that it is possible to maintain the constant speed and accurate position detection by the sensing means 40 Done.

The cut section 50 is a structure that allows a pair of cut-in 51, 52 is operated to the desired length of the tube member 1 that proceeds in a tubular shape to be cut.

The cut 50 is cut by the cutting means 51 and 52 by the detecting means 40 which detects the length of the cut portion of the tube member 1 and sends a signal thereof. 51 and 52 are fixed to the cylinders 53 and 54, respectively, so that a signal is cut at the correct position in accordance with the cutting timing by sending a signal from the sensing means 40 to the cylinders 53 and 54. .

The sensing means 40, which determines the length of the tube member 1, is printed with a mark 2 indicating the unit length on the outer circumferential surface of the tube member 1 as shown in the overall apparatus diagrams of FIGS. When the signal is sent by the detection sensor 41 which detects the mark position, the cylinders 53 and 54 are operated so that the cuttings 51 and 52 are advanced and the cutting is performed therebetween. It is possible to do.

In this case, the mark 2 for displaying the unit cutting length is provided on the outer circumferential surface of the tube member 1.

Then, the position sensor 42 is positioned next to the cut-in 51 and 52 positions of FIG. 1, so that the detection signal can be obtained to be cut to the correct length.

That is, the length of the tube member 1 in the longitudinal direction in which the position sensor 42 is cut from the cut-in (51) 52 in the longitudinal direction to be transported, the end of the tube member 1 is detected The instantaneous signal is sent out so that the cut-in 51 and 52 are operated by the cylinders 53 and 54 so that the cut is made therebetween.

Therefore, according to this position sensor 42, there is an advantage that the mark 2 indicating the unit length can be applied and used even when the tube member 1 is not marked.

At this time, the position sensor 42 is to be able to adjust the position in the conveying direction of the tube member (1) to set the desired cutting position.

Further, in the case where the tube member 1 provided with the aforementioned mark 2 is to be sensed by the detection sensor 41, the position sensor 42 is provided in plural, and the position sensor ( By configuring the circuit so as to sense by the electronic control unit 42, the tube member 1 may be transported without being cut continuously in the event of a malfunction such as not detecting the position of the mark by the detection sensor 41. The position sensor 42 is to have a malfunction prevention function to stop the device.
