BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel reversing and turning device. For example, it can be used to turn the gable panels of a housing unit upside down and to rotate them horizontally.

0002

[Background technology] The housing units that make up the unit housing are
The ceiling panel, floor panel, and end panel are individually produced in advance on each panel production line, and these panels are transported to an assembly line and assembled there. That is, the ceiling panel and the floor panel are arranged vertically in a horizontal state, and a pair of end panels are arranged between the ceiling panel and the floor panel, and these are connected to form a box shape.

0003

[Problem to be solved by the invention] Each panel production line,
Alternatively, on lines that transport panels manufactured on these lines to assembly lines, it may be necessary to change the orientation of the panels due to processing conditions or the like. For example, there may be cases where it is necessary to turn the front and back sides of the panel, or to simultaneously turn the panel at a predetermined angle in the horizontal direction, from the viewpoint of workability during welding and welding quality.

However, even when changing the posture of the panel,
Since the panel itself is large and heavy, it must be carried out using a hoist, for example. However, in order to change the posture using a hoist, the operator first lifts one end of the panel to a vertical position, and then the worker grabs the other end (lower end) and pulls down the panel and flips it over. I have to let it happen. In particular, if the panel is to be rotated horizontally at the same time, a plurality of hoists will be required, making the work more cumbersome. Therefore, changing the posture of the panel places a heavy burden on the operator.
Moreover, there are problems in that it is dangerous and work efficiency is low.

It is therefore an object of the present invention to provide a panel reversal method which eliminates the above-mentioned conventional drawbacks, reduces the burden on the operator, and allows the panel posture to be changed safely and efficiently. The purpose of the present invention is to provide a turning device.

[0006]

[Means for Solving the Problems] Therefore, the panel reversing and turning device of the present invention includes a hoist that is supported by a structure and is capable of hoisting and rewinding a lifting chain, and a hoist that is horizontally supported by the hoisting chain of the hoist. a guide rail that can be pivoted in the horizontal direction; a pair of support arms whose upper ends are movably supported by the guide rail; and a spacing adjustment mechanism that causes the pair of support arms to move toward and away from each other; A reversing arm whose substantially middle portion is supported rotatably about the same horizontal axis at the lower end of each support arm, a locking mechanism for locking each reversing arm in a horizontal state, and a locking mechanism provided at each end of each of the reversing arms. The device is characterized by comprising an engaging portion that is provided and holds the panel.

[0007]

[Operation] After rewinding the hoist's lifting chain and aligning the pair of reversing arms with the height position of the panel, the interval between the pair of reversing arms is adjusted to correspond to the width of the panel by the interval adjustment mechanism. Here, after engaging the engaging portions provided at both ends of each reversing arm with the panel, the hoisting chain of the hoist is wound up, and the panel is lifted up. When the locking mechanism 75 is released and both reversing arms are rotated 180 degrees in the lifted state of the panel, the front and back of the panel are reversed. Eventually, when both reversing arms return to a horizontal position, the locking mechanism locks the reversing arms in a horizontal position, and then the guide rail is turned horizontally.
The panel is pivoted horizontally. Therefore, there is less burden on the operator, and the posture of the panel can be changed safely and efficiently.

Next, the working procedure in the end panel production line 26 will be explained. First, the two columns 15 produced by the column production line 24 and the two short side beams 16 produced by the short side beam production line 25 are transferred to the first conveying device 4.
It is carried into the cart 57 on the lifter 51 of No. 1 and arranged as shown in FIG. In other words, two pillars 15 are arranged on the horizontal upper surface of the cart 57 with the surface on which the shikiguchi 17 is attached facing upward, parallel to the transport direction, and spaced apart from each other by a predetermined distance, and each of the two pillars 15 is A short side beam 16 having a U-shaped cross section is arranged between the ends with the U-shaped groove facing upward.

The cart 57 advances from the lifter conveyor 53 to the transport conveyor 55, and before being transferred to the lifter conveyor 54, several parts of the U-shaped end of each short side beam 16 are connected to the pillar 15.
A rectangular frame 18 is formed by tack welding. Therefore, the column 15 and the short side beam 16 are positioned so that the outer surface of the column 15 and the web surface of the short side beam 16 are aligned with each other, and tack welding is performed in this state. and can be attached accurately in a predetermined positional relationship. After all the tacking work is completed and before the cart 57 is transferred to the lifter conveyor 54, the frame 18 is lifted up by the reversing and turning device 42, turned over and turned horizontally by 90 degrees (Fig. 15 reference).

For this purpose, the support frame 63 is connected to the rail 62A.
, 62B and positioned on the carriage 57. Here, after driving the motor 66 of the hoist 64 to rewind the lifting chain 65 and aligning the pair of reversing arms 74A, 74B with the height position of the frame 18 on the trolley 57, the pair of reversing arms 74A , 74B by the interval adjustment mechanism 69
This corresponds to the width of the frame 18.

After that, the engagement pins 84 of the engagement portions 81 provided at both ends of each of the reversing arms 74A, 74B are pushed in and inserted into the holes of the joint 17 of the frame 18, and then the hoist 64 is inserted.
The motor 66 is driven to hoist the lifting chain 65. Then, the frame body 18 is lifted up from above the cart 57. Thereafter, the support frame 63 is moved forward along the rails 62A, 62B by a predetermined distance and then stopped. Here, the engagement pin 79 of the lock mechanism 75 is inserted into either of the engagement tubes 76, 7.
After pulling out from 7, both reversing arms 74A and 74B are pulled out from 1.
When rotated 80 degrees, the front and back sides of the frame body 18 are reversed. At this time, since both reversing arms 74A and 74B rotate around the rotating shaft 73, the frame body 18 can be reversed with a relatively light force.

Thereafter, when both reversing arms 74A, 74B return to their horizontal positions, the engaging pin 79 of the locking mechanism 75 is inserted into the engaging cylinder 7 of either of the reversing arms 74A, 74B.
6, 77 to lock the reversing arms 74A, 74B in a horizontal state, and in this state, the guide rail 67
The frame body 18 is rotated by rotating it 90 degrees in the horizontal direction. At this time, since the reversing arms 74A and 74B are locked in a horizontal state, horizontal rotation is also safe. Thereafter, the support frame 63 is moved forward along the rails 62A and 62B, and the frame body 18 is carried into the second transport device 43.

The frame 18 carried onto the second conveyor 42 is conveyed in a horizontal position with the two pillars 15 located in front and behind each other by the drive of chain conveyors 93A and 93B on both sides. Eventually, when the axis of the pillar 15 on the front end side reaches the positioning line L connecting the centers of the welding robots 44A, 44B, the driving of the chain conveyors 93A, 93B is stopped (see FIG. 15). Here, when the cylinder 99 of the elevating mechanism 95 is driven, the roller 98 descends along the inclined surface of the inclined table 96, so that the guide frames 94A, 94
4B is lowered.

[0033] As a result, the chain conveyors 93 on both sides
When the transport surfaces A and 93B are lowered, the frame body 18 supported by the transport surface also lowers, and the pillars 15 in front and rear thereof are supported by the receiving members 101A, 101B, 102A, and 102B. In other words, the frame body 18 is connected to the chain conveyor 9
3A, 93B, and positioning in the vertical direction is performed by receiving members 101A, 101B, 102A, 102B.

When the pusher 107 of the second positioning mechanism 109 is driven, the frame 18 is moved in the width direction and is regulated by the stoppers 104 and 105. In other words, positioning in the width direction is performed. Further, after protruding the stopper 111 of the third positioning mechanism 110, the clamp piece 1
When the column 12 is clamped, the column 15 in front of the frame 18
is held between the stopper 111 and the clamp piece 112, and positioning in the transport direction is performed.

After positioning in the vertical direction, width direction and conveyance direction is performed in this way, the entire joint end surface of the column 15 and the short side beam 16 is welded by the welding robots 44A and 44B on both sides, as shown in FIG. Continuously weld the circumference. first,
After the welding heads of the welding robots 44A and 44B are positioned inside, welding is carried out while moving upward, then welding is carried out while moving the top wall outward, and finally welding is carried out while moving downward. . As a result, the short side beam 1
The entire circumference of the U-shaped end face of No. 6 can be continuously welded from the outside with the welding head always facing downward.

After that, each positioning mechanism 109, 110 is released, and the guide frame 9 is moved by the lifting mechanism 95.
After raising chain conveyors 4A and 94B, chain conveyors 93A and 93B on both sides are driven. As a result, when the axis of the column 15 on the rear end side of the frame 18 reaches the positioning line L connecting the centers of the welding robots 44A, 44B, the driving of the chain conveyors 93A, 93B is stopped. Here, after positioning in the vertical direction, width direction, and transport direction in the same manner as above, welding robots 44A, 44B on both sides
The entire circumference of the joint end face between the column 15 and the short side beam 16 is continuously welded by the following steps. The frame body 18 that has been completely welded in this manner is transported by the third transport device 45, and is then transported to the general assembly line 27.

Therefore, according to this embodiment, in the end panel production line 26, the two columns 15 and the two short side beams 16
a first conveying device 41 that circulates and conveys a trolley 57 for temporarily attaching and forming a rectangular frame 18; and a reversing and turning device that lifts the frame 18, turns it upside down, and rotates it horizontally. 42, a second transport device 43 that transports the frame 18 in a horizontal position with the two pillars 15 located in front and back while supporting the two pillars 15; Two welding robots 4 welding the joint with the side beam 16
4A and 44B, it is possible to perform tack welding of the two columns 15 and the two short side beams 16 to full circumference welding continuously during the assembly process, making it easier for workers to The end panels 3 can be efficiently and continuously produced without putting a burden on the.

In the first conveying device 41, two columns 15 are arranged in parallel with each other at a predetermined distance on a cart 57 that is circulated and conveyed, and a distance between each end of the two columns 15 is arranged. The short side beam 16 with a U-shaped cross section was placed with the U-shaped groove facing upward, and the tack welding was performed in this state. Since the side surfaces and the web surfaces of the short-side beams 16 are tack-welded in a state where they are aligned, the columns 15 and the short-side beams 16 can be tack-welded accurately in a predetermined positional relationship.

Furthermore, since the frame body 18 conveyed by the first conveyance device 41 is turned over before being conveyed by the second conveyance device 43, the short sides constituting the frame body 18 are After the U-shaped groove of the beam 16 is changed from an upward position to a downward position, the beam 16 can be transported by the second transport device 43. When the U-shaped grooves of the short side beams 16 are directed downward, welding can be performed continuously from the outside along the U-shaped ends of the short side beams 16 with the welding head always facing downward.
Welding work by the welding robots 44A, 44B can also be performed efficiently.

At this time, the frame 18 is moved horizontally by 9
After the frame body 18 is rotated by 0 degrees and changed to a posture in which the two pillars 15 constituting the frame body 18 are located at the front and rear in the transport direction, the second transport device 43 transports the frame body 18.
Chain conveyor 93A, 93B with simple structure
It can be configured by In other words, the chain conveyors 93A and 93B, which are structurally simpler than the first conveying device 41 which has a structure of conveying a trolley, can be used since it is only necessary to convey while supporting the two pillars 15 located at the front and rear. Can be done.

Further, guide frames 94A and 94B that support the conveyance surfaces of chain conveyors 93A and 93B constituting the second conveyance device 43 are provided so as to be movable up and down.
An elevating mechanism 95 is provided that raises and lowers the conveyance surfaces of the chain conveyors 93A and 93B by raising and lowering the guide frames 94A and 94B. receiving members 101A to 103B that position the frame body 18 in the vertical direction while being spaced from the conveyance surface, and positioning mechanisms 109 and 1 that position the frame body 18 in the width direction and the conveyance direction.
10, when the frame body 18 is conveyed to the welding position by the chain conveyors 93A, 93B, when the conveyance surface of the chain conveyors 93A, 93B is lowered by the lifting mechanism 95, the frame body 18 is separated from the conveyance surface. In this state, it is supported by the receiving members 101A to 103B and positioned in the vertical direction.

At the same time, the welding robots 44A, 44B can perform welding after positioning in the width direction and transport direction by the positioning mechanisms 109, 110, so that the welding between the column 15 and the short side beam 16 can be performed with stable quality. can be kept. After the welding is completed, if the conveyance surfaces of the chain conveyors 93A, 93B are raised by the elevating mechanism 95, conveyance can be carried out immediately, so that efficient welding work can be carried out.

The reversing and rotating device 42 also supports a guide rail 67 horizontally and rotatably in the horizontal direction on a lifting chain 65 of a hoist 64 supported on a support frame 63, and a pair of support arms are attached to the guide rail 67. 68A, 6
8B so as to be freely movable, and each support arm 68A
, 68B has a structure in which the intermediate portions of the reversing arms 74A and 74B, each having an engaging portion 81 at both ends, are rotatably supported at the lower end portion of the lower end portion of the reversing arms 74A and 74B. By rotating the arms 74A and 74B by 180 degrees, the frame 18 can be turned over, and by rotating the guide rail 67, the frame 18 can be rotated horizontally. Therefore, the burden placed on the operator is small, and the posture of the frame 18 can be changed efficiently.

Moreover, a pair of reversing arms 74A, 74B
Since the spacing adjustment mechanism 69 is provided to move the frames 18 toward and away from each other and adjust the spacing, even frames 18 of various sizes with different width dimensions can be efficiently reversed and turned. In addition, each support arm 68A, 6
8B and each reversing arm 74A, 74B is provided with a locking mechanism 75 that locks each reversing arm 74A, 74B in a substantially horizontal state. Since the work can be carried out with 74A and 74B locked in a substantially horizontal position, the safety of the work can be ensured.

Furthermore, since the frame 18 transported by the second transport device 43 is transported in the same posture by the third transport device 45, that is, the two pillars 15 are positioned one behind the other. Since the short side beams 16 are transported in a state in which they protrude outward from both sides of the third transport device 45, other treatments such as anti-corrosion treatment after welding are carried out during transport. etc. can also be done.

In the above embodiment, the reversing and turning device 42 for reversing and rotating the end panel 3 has been described, but the present invention is not limited to the end panel 3, but can also be applied to the ceiling panel 1.
