2. Description of the Related Art In general, in the production of a drum, first, a thin plate cut into a rectangular shape is formed into a cylinder, and a seam is overlapped and welded to produce a cylinder body (hereinafter, drum body). . Then, the drum body is subjected to ring processing and end flange processing, and a main plate and, if necessary, a top plate are attached by winding or the like to manufacture. In such a case, since there is a step in the welded portion as it is, the winding process may be incomplete and the sealing performance may be reduced. Further, at the time of painting, the paint is thin or hardly painted at the step portion of the welded portion, thereby impairing the corrosion resistance.

The above-mentioned technique (hereinafter referred to as "prior art") relates to a main body of a drum can welding pressurizing apparatus for pressurizing a welding portion, and does not mention a means for transporting a drum can. With respect to the transporting means, generally, cylindrical articles such as cans are widely rotated (rotated) by providing a slope to a target location.

However, when the method of the prior art is applied to a drum, the position of the welded portion moves in the circumferential direction due to the rotation during transportation. As a result, it is necessary to return the position of the welded portion to a predetermined position after transport. For that purpose, a device for detecting the position of the welded portion and a positioning means in the circumferential direction are required. As a result, there is a problem that one step (positioning) is increased before pressurization of the welded portion, and the apparatus becomes complicated.

[0010] Apart from this, a method of transporting a drum, a crane, a movable frame, or the like while paying attention so that the position of the welded portion of the drum body does not rotate in the circumferential direction is also conceivable. However, in this case, it is difficult to perform quick handling. In normal load handling, work efficiency is prioritized, and it is inevitable that the position of the welded portion is shifted due to rotation.

In addition, these cargo handling devices are generally heavy and have a large inertia as compared with the drum can body. As a result, acceleration and deceleration are more difficult than with the drum body alone, and a positioning operation is separately required. Further, also in the work of setting the drum can body to the support die, a truck, a moving gantry, and the like require separate unloading means, and also require an unloading operation. Even when a crane is used, it is necessary to pay close attention so that, for example, the support die and the tongue of the crane do not collide, and the working efficiency is impaired.

[0013] The body charging means takes the body of the drum into the welding part pressurizing device body, moves it to a predetermined position on the support die, and lowers it. This is performed by using a moving means such as a conveyor or a jig, and further lowering the moving means. First, the body charging means moves the conveyed drum body in the axial direction. Since it is moved in the axial direction, the above-described positional relationship of the welded portion can be maintained. If the support die is elongated in the axial direction of the drum body, these collisions can be avoided by moving a moving means such as a conveyor in parallel with the support die. As described above, the shape of the support die is arbitrarily elongated because the welded portion of the drum can body is linear, and as a result, the device can be compactly assembled.

Further, by providing a plurality of pairs of traveling belts and connecting them, it is possible to cope with a case where the transport distance is long. Further, in this case, the transfer timings on the outlet side of the welding machine and the inlet side of the welding part pressing device main body can be set or controlled independently of each other. As a result, the processing efficiency of the entire apparatus is improved.

Since the outer surface of the drum body being conveyed is in contact with the two traveling belts, rotation in the circumferential direction is restricted. Further, since the drum body is transported in the axial direction, the transport speed can be increased. When transporting in a direction other than the axial direction, there is a limit to speeding up. This is because the outer peripheral surface receives wind pressure and thus tends to sway, and the higher the speed is, the stronger the wind pressure is, the greater the sway is, and it becomes difficult to carry out a stable conveyance. According to the present invention, by transporting in the axial direction, the outer peripheral surface is not subjected to wind pressure, thereby preventing swaying. In addition, since air resistance is reduced, the transport speed can be increased.

In this example, the torso charging means 30 comprises a pair of running belts 31 like the torso conveying means 20, and the running belt 31 is wound around a pulley 32. Further, at least one pair of pulleys among the pulleys 32 is driven to cause the traveling belt 31 to travel. Further, all the pulleys 32 are provided with cylinders 33 and can be moved up and down. These cylinders 33 are simultaneously operated by an air pipe or an electric circuit (not shown) to move all the pulleys 32 up and down at the same time.

If the connecting portion between the body conveying means 20 and the body charging means 30 is too far away, the drum can body 1 swings at the connecting portion, and the position of the welded portion 1a may be shifted. Therefore, it is preferable to arrange both of them partially overlapping (overlapping). In this example, the respective traveling belts 21 and 31 are arranged so as to partially overlap each other. In some cases, both pulleys 22 and 32 may be coaxial pulleys.

The running belt may be a belt made of rubber or other material having some friction. The cross-sectional shape of the traveling belt is not particularly limited, but in the case of a round belt, since the contact with the outer surface of the drum can body is in linear contact, the rotation in the circumferential direction is not sufficiently restricted, and the position of the welded portion may be shifted. . Further, in the case of a round belt, it is expected that the drum can body that comes into contact with the torsion rotation of the running belt rotates. Therefore, it is preferable to use a belt having a polygonal cross section such as a hexagon. In this case, in order to reliably restrain the drum body from rotating in the circumferential direction, the position and angle of the pulley and the like are adjusted and arranged so that the outer surface of the body and one surface of the belt are in surface contact.

Next, the body charging means 30 is mounted on the traveling belt 3.
1, the drum body 1 is welded to the pressurizing unit 4
From the entrance to the back. When the drum body 1 moves to the back, the end 1b hits the stopper 41, and the movement of the drum body 1 is stopped. In this case, it is preferable to stop the traveling of the traveling belt 31 immediately, but it is unavoidable that the outer surface of the drum can body 1 and the traveling belt 31 slip slightly. In this case, the sliding direction is the axial direction, so that the position of the welded portion 1a does not shift.

After that, the body charging means 30 includes the pulley 31
Is lowered to lower the drum body 1 on the support die 2, and the welded portion 1 a of the drum body 1 is set on the surface of the support die 2. After setting, the stopper 4 of the drum body 1
The end on the side opposite to 1 (entrance side) is pressed by a jig or the like (not shown) and restrained by the stopper 41 and this jig. As described above, when pressurizing the welded portion of the drum body, it is preferable to restrain the drum body in order to prevent the drum body from swinging on the support die.

After the drum body 1 is set on the surface of the support die 2, the pressure roller 13 of the welding part pressing device main body 4 is used to
Pressurization of the welded portion 1a is performed. From the viewpoint of processing efficiency, it is better to discharge the drum body 1 after the pressurization process in a direction different from the charging direction. For example, after being lifted upward by an adsorber or the like, it may be transported in the lateral direction. Further, the discharge processing of the drum can body after the completion of the press processing and the charging of the next drum can body are interlocked with each other, so that the press processing of the welded portion can be made more efficient.
