Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for forming a panel by a tube body, and more particularly to a tube transfer apparatus suitable for supplying a bent tube body by a panel bender.

<Conventional technology and its problems> Large-scale industrial boilers such as power plant boilers have water tubes on the wall of the boiler, and heat transfer tubes are also placed in the flue to save economizers, superheaters, and reheat. It is used as a container. For example, a economizer is placed in the flue of a boiler, but the tubes are bent in multiple steps to increase the heat recovery rate, and a plurality of bent tubes form one heat transfer panel. By arranging a large number of these heat transfer panels with a header or the like, an integrated economizer is formed as a whole. The number of bent pipes (coils) varies depending on the type of boiler, but a few are hundreds, and a large number are in the thousands. Therefore, an apparatus for efficiently manufacturing a large number of panels has been demanded, and the inventors have proposed the manufacturing thereof.

<Technology Prerequisite for Constituting the Present Invention> FIG. 5 shows an outline of a manufacturing process of a panel manufacturing apparatus separately proposed by the inventors. In the figure, reference numeral A is a pipe processing portion, B is a processing pipe arrangement portion, C is a welding portion, D is an inspection portion, and E is a panel manufacturing portion. A conveyor for conveying a processed product between these portions A to E. By connecting with, it is configured as an integrated device as a whole.

First, regarding the pipe working portion A, reference numeral 1 is a pipe stocker, 2 is a groove forming machine that forms a groove at the end of the pipe body supplied from this stocker, and 3 is a pipe that has completed groove formation. It is a multi-stage vertically stacked stocker that stacks a large number of bodies in the vertical direction, and it is configured to stock different types of things such as those with different lengths and diameters, and supply the necessary tubular body. Reference numeral 4 is a bender for bending the pipe body supplied from the stocker 3, and numerical control (N
C) is performed.

The pipe bent by the vendor 4 is placed on the belt conveyor 5a via the transfer device 20, and the pipe on the conveyor is further transferred to another conveyor 5b. Here, each pipe is arranged as a panel on the roller conveyor 6 by the pipe arrangement device 7 so as to be welded, and then transferred to the welding portion C in this state to weld the pipes. After passing through the inspection department D and the panel manufacturing department E, it becomes a finished product.

In the above device, in order to arrange the pipe on the roller conveyor 6, the pipe bent into various shapes must be accurately arranged at a predetermined position. Power, high transportation capacity, accurate operation, etc. are required.

<Purpose of the present invention> The present invention has been made in view of the above-mentioned needs, and it is an object of the present invention to provide a device capable of accurately transferring and arranging tubular bodies of various shapes.

<Summary of Means> In short, the present invention relates to a pipe storage unit (1, 3), a pipe body processing unit (A) having a groove processing machine (2) and a bender (4) with numerical control, and a bent pipe. Conveying devices (20, 5a, 5b) for conveying to the arranging part (B), a plurality of pipe arranging devices (7) for grasping the conveyed pipes by a grasping device and arranging them according to the panel arrangement on the roller conveyor (6). , A welding part (C) having a welding device, an inspection part (D) for inspecting the welding part, and a panel manufacturing part (E) for attaching a fitting and the like to form a completed panel.
And a pipe transfer panel forming apparatus.

<Examples> Examples of the present invention will be described below.

In FIGS. 1 to 4, reference numeral 21 is a steel frame standingly arranged around the roller conveyor 6, which is a tubular body arranging portion, and 2
Reference numerals 2, 23, and 24 are guide rails supported by these steel frames. Reference numerals 25 and 26 denote support beams that move along the guide rails, with respect to the support beams, the pipe placement device main body 27
And 28 are mounted so as to be movable along the support beam. Servo control units 29 and 30 are attached to the support beams, respectively, and bear a part of the movement of the support beams and the control thereof, and in some cases, the control of the main body of the tube placement device.

Fig. 4 shows the details of this tube placement device,
28 is shown as an example.

In the figure, reference numeral 31 is a traverse drive unit for moving the main body 28 along the beam 26, and 32 is a clamp device drive for raising and lowering the arm 36 in the arm post 33 and operating the tubular clamp device 34 formed at the lower end of the arm 36. It is a unit. Further, reference numeral 35 is a balancing device arranged in parallel with the arm post 33, which is composed of a hydraulic or pneumatic cylinder, and a clamping device 34.
The center of gravity changes by clamping the bending tube,
When a moment is generated in the arm post 33, it is used to cancel it.

In the apparatus having the above configuration, when the pipe body formed into a predetermined shape is carried by the conveyor 5b, each support beam moves to the position of the conveyor 5b along the guide rail, and the pipe body is arranged. Move the device body along the beam. Next, the clamp device is lowered to clamp the pipe body, and then the support beam is moved onto the roller conveyor 6 and the main body is moved to arrange the pipe body 40 at a predetermined position. That is, the moving device main body can freely move to a predetermined position by moving the beam and moving itself along the beam in a direction orthogonal to the moving direction of the beam.

By repeating the above operation, the pipe placement device places each pipe at a predetermined position so that it can be welded.
When the arrangement of the panels is completed, the rollers are transferred to the next welding process by the roller conveyor 6 in this arrangement state.

<Effect> By carrying out the present invention, it is possible to quickly and surely dispose the tubular body processed and formed into various shapes at a predetermined position.
