[Industrial applications]

 The present invention relates to improvement of an assembling apparatus suitable for use in continuous manufacturing equipment for box structures.

[0002]

[Prior art]

 For example, to explain the conventional technology for continuous manufacturing equipment for box structures as shown in FIG. 1, the plate material 1 forming the skin plate of the box pillar is a trolley (not shown) traveling on a rail (not shown), Alternatively, it is sent in the direction of the arrow by a conveyor (not shown) such as a conveyor. The plate material 1 is gas-cut into four pieces by the gate-shaped fusing equipment 2 to obtain the skin plates 3a, 3b, 3c, 3d. The skin plates 3a and 3d at both ends are sent to the automatic groove processing machine 4, where predetermined grooves necessary for welding are formed and are conveyed downstream, that is, in the arrow direction. The two intermediate skin plates 3b and 3c are conveyed in the directions of the arrows. When a groove is required for these 3b and 3c, an automatic groove processing machine 4a is separately installed. After that, the preassembled diaphragm 5 is fed from another route to the part where the skin plate 3c is marked at a predetermined position, and the diaphragm 5 is marked on the skin plate 3c as shown in the figure. Temporarily set up at the writing position. When the temporary attachment of the diaphragm 5 is completed, the skin plates 3a and 3d, which have grooves formed on both sides of the skin plate 3c, are erected 90 ° upright by the assembling device and the lower end of the skin plate 3c is rotated. Are abutted so as to be mounted on both end edges of the. The two skin plates 3a and 3d are temporarily attached to the diaphragm 5 and / or the skin plate 3c to form a U-shaped column (upward U-shape).

Next, the skin plate 3b conveyed in the direction of the arrow is conveyed by the same conveyer as 3a, or is supplied and placed in the upper opening of the U-shaped column by the transfer / supply means of another route. There is known a means for temporarily fixing the skin plate 3b to the other skin plates 3a and 3d which are in contact with the skin plate 3b to form the shaft 7 in the temporarily attached state.

The assembling device for the skin plates 3a, 3c, 3d is arranged such that the skin plate 3c, to which the diaphragm 5 is temporarily installed, is erected on both sides of the loading stationary line by the action of a cylinder on both end faces of the diaphragm 5. The inversion lines for carrying in the skin plates 3a and 3d are arranged in parallel. (For example, refer to JP-A-61-162273)

[0005]

[Problems to be solved by the device]

 In the above assembling apparatus, the inner ends of the internal members of the skin plates 3a and 3d forming the carry-in reversal line are cantilevered by the apparatus main body, and the cylinders are connected to the outer ends of the guide members. By the action, the outer end of each guide member is rotated upward toward the loading stationary line direction of the skin plate 3c, and the skin plates 3a and 3d placed on this guide member are brought into contact with both end faces of the diaphragm 5. Since it is upright, the set positions of the skin plates 3a, 3d on both sides with respect to the skin plate 3c guided and installed at a predetermined position are standardized to a fixed position, and the thickness of each skin plate 3a, 3c, 3d, And the width is also standardized.

Therefore, the thickness of each skin plate, in particular, when the skin plate 3c to which the diaphragm 5 is temporarily attached is thick and the other skin plates 3a and 3d are thin, or the width of each skin plate is different from that of the assembling apparatus. If the width is wider or narrower than the specification, U-shaped assembly cannot be performed with this device. Therefore, individual assembling devices should be installed according to the thickness and width of the skin plates that make up the box structure. There are operational and economic challenges that must be addressed.

An object of the present invention is to adjust the height relationship of each skin plate and the horizontal setting position relationship in response to a change in the width and thickness of each U-assembled skin plate. The purpose is to have one machine perform U-shaped assembly with skin plates corresponding to the size of the box structure.

[0008]

[Means for Solving the Problems]

 The structure of the present invention, which solves the problems of the prior art, is a skin plate carry-in reversal line which is erected and abutted on both end faces of the diaphragm on both sides of the fixed line of the skin plate where a diaphragm is temporarily attached to a predetermined position on the upper surface. Are arranged in parallel with each other, and have a skin plate guide means, a skin plate upright reversal means, and a skin plate up-and-down adjusting means in the carry-in reversal lines on both sides, and the above-mentioned carry-in stationary line. At least two reversing mechanisms are provided, which are movable and adjustable in the direction orthogonal to the longitudinal axis direction.

[0009]

[Action]

 Depending on the width of each skin plate that composes the box structure, both skin plates carried in and guided to the carry-in reversal line are moved and adjusted by the reversing mechanism in the direction orthogonal to the longitudinal axis of the skin plate temporarily attached with the diaphragm. To be done. In addition, the left and right skin plates are adjusted up and down to correspond to the thickness of the skin plate to which the diaphragm is temporarily attached, and a U-shaped assembly that suits the properties such as the width and thickness of the skin plate can be done with one machine. .

A stopper 17 for positioning the skin plates 3a and 3d is provided so that it can be taken out.

Below the respective loading pedestals 16, two parallel guide rails 18 which are orthogonal to the longitudinal direction of the loading stationary pedestal 13 and laid on the foundation 11 are provided. As shown in FIGS. 2 and 3, the guide rail 18 passes under the carry-in stationary pedestal 13 and is commonly arranged between the carry-in pedestals 16 arranged symmetrically.

A reversing mechanism A capable of intervening in the space between the left and right loading pedestals 16 is mounted on the guide rail 18 so as to be movable. The reversing mechanism A will be described below. 19 is a trolley provided with wheels 20 traveling on the guide rail 18, and the trolley 19 is provided with a substrate 22 in a horizontal posture that moves up and down by a cylinder 21 mounted on the trolley 19.

[0016]

[Explanation of action]

 Next, the operation of the first embodiment will be described. The skin plate 3c on which the diaphragm 5 is temporarily erected in advance is carried in from the direction of the arrow to the central loading stationary pedestal 13 shown in FIG. 2, and the skin plate 3c is guided by the guide roller 12 so that the tip thereof becomes the stopper 14. It is stopped and positioned at the contact position. Similarly, the two skin plates 3a and 3d, which stand upright and abut on both end faces of the diaphragm 5, are individually loaded into the left and right loading pedestals 16 in the direction of the arrows, and the tips are in contact with the stoppers 17 at the positions. Stopped and positioned.

When the skin plates 3a, 3c, 3d are loaded and set on the respective pedestals 13, 16, the cylinder 21 causes the substrate 22, that is, the skin plates 3a, 3d to move to the right side of FIG. It is promoted higher. That is, the lower surfaces of the skin plates 3a and 3d are raised so that they are located slightly above the upper surface of the skin plate 3c, and the carriage 19 moves toward the loading stationary pedestal 13 while being separated from the guide rollers 15. When the inner ends of the skin plates 3a and 3d come into contact with the side end surfaces of the diaphragm 5, the carriage 19 stops moving. By this stop signal, another cylinder 25 is activated, and when the tilting plate 24 is gradually tilted as shown in the left side of FIG. 2, the skin plates 3a and 3d slide down on the guide roller 15 by their own weight, and the skin plate 3a and 3d slides down. The lower ends of the plates 3a and 3d are mounted and locked on the upper surface of the edge of the horizontal skin plate 3c as shown in FIG. In this state, the tilting plate 24 is raised, and the surfaces of the skin plates 3a and 3d are brought into contact with the side end surfaces of the diaphragm 5. With this posture restrained, the skin plates 3a and 3d and the diaphragm 5 are temporarily attached by welding means, and the U-shaped assembly as shown in FIG. 5 is completed.

When the skin plates 3 a and 3 d and the diaphragm 5 are temporarily fixed and fixed and the U-shaped assembly is completed, the tilting plate 24 is returned to the horizontal posture by the reverse operation of the cylinder 25, and the substrate 22 is moved by the reverse operation of the cylinder 21. The carriage 19 is lowered to a predetermined position, the carriage 19 is moved and stored between the carry-in bases 16, and the levels of the guide roller 26 and the guide roller 15 are set at the same height to prepare for the next work. The U-shaped assembled structure left on the carrying-in stationary pedestal 13 is carried out to the next step by inserting the stopper 14 below the surface of the guide roller 12, and the skin plate 3b is removed as shown in FIG. The box structure is temporarily attached to form a box structure as shown in FIG.

When the embodiment shown in FIGS. 2 to 4 is used in the continuous manufacturing equipment for the box structure shown in FIG. 1, the carrying-in stationary pedestal 13 is used in the transfer line of the skin plate 3c, and The carry-in pedestal 16 is adapted to communicate with the transfer line of the skin plates 3a and 3b. Further, the present invention is not necessarily incorporated in a continuous manufacturing facility for a box structure, but can be used for U-shaped assembly of a batch type box structure using a skin plate carried by another carrying means. It is not specified in the use cases shown in.

Next, the details of the second embodiment will be described with reference to FIGS. This embodiment shows a practical device of the reversing mechanism A of the device shown in FIGS. In this embodiment, members common to those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted by incorporating the above description.

In this embodiment, the use of the support rod 23 in the first embodiment is omitted. That is, the worm jacks 27 are symmetrically attached to the left and right ends of the carriage 19 in a vertical posture. The worm jack 27 corresponds to the cylinder 21 in the first embodiment. A motor 29 mounted on the carriage 19 is connected to one of the worm jacks 27 via a transmission mechanism 28, and both worm jacks 28 are connected by a transmission shaft 30 to drive the motor 29. Thus, both worm jacks 27 are operated simultaneously to adjust the board 22 up and down.

Horizontally-positioned cylinders 25 are arranged on both sides of a horizontal guide roller 26 mounted and supported on the tilting plate 24. The outer end of the cylinder 25 is the outer end of the substrate 22. It is pivotally supported. This structure is the same as that of the first embodiment except that the cylinder 25 is in a horizontal posture.

The upper ends of arms 31 tilted downward toward the loading stationary pedestal 13 are fixed to the left and right inner ends of the tilting plate 24, and the lower tilted ends of the arms 31 are fixed to the dolly 19. Is rotatably supported on the inner end of each of the cylinders, and the operating rod ends of the two cylinders 25 are also supported on the inclined upper ends of the arms 31, and the tilting plate is moved by the operation of the cylinder 25 via the arms 31. 24 is rotated in the direction of the arrow in FIG. 7 to be rotated to a vertical posture as shown by a virtual line.

A motor 32 is mounted on the outer end of the carriage 19. The motor 32 is connected to the shaft 34 of the outer wheel 20 via a transmission mechanism 33 so that the drive of the motor 32 is transmitted. It is transmitted to the wheel shaft 34 through the mechanism 33 so that the carriage 19 can move on the guide rail 18.

The second embodiment described above has a basic configuration similar to that of the first embodiment, but it is significant that the height of the reversing mechanism A is made compact by setting the cylinder 25 in a horizontal posture. Since the operation is substantially the same as that of the second embodiment, its detailed description will be omitted.
