Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a positioning and holding device for a transformer material or floor material, which holds the transformer material or floor material upright so that its upper end surface is at a predetermined height.

For example, a ship side panel block can be manufactured by standing and welding double rows of transformer materials and longitudinal materials perpendicular to each other on one skin material, or two panels with longitudinal materials attached. When manufacturing a double-structure panel block for the bottom of a ship by sandwiching and welding double rows of floor materials between skin materials, conventionally known assembly methods include the ``loose material distribution method,'' `` These include the "frame assembly method", the "line welder (longue attachment) and transformer material bulk insertion method", and the "(transformer material advance) longitudinal material bulk insertion method". However, in all of these conventional methods, aggregates such as transformer materials are held upright on the skin material and welded, so various devices such as holding devices and welding devices that operate from above interfere with each other. The disadvantage is that it is difficult to automate welding.

Therefore, when developing a new device that can automate welding, it is recommended to hold the double-row transformer material or floor material upright so that the upper end surface, that is, the mounting surface, is at a predetermined height. This is convenient because a predetermined shape can be obtained by simply placing a skin material on top of it.

The present invention was developed with attention to this point, and includes a pair of holding device bodies that can be moved toward and away from each other in the horizontal direction on a cart that can be moved vertically on rails, and a space between the two holding device bodies. A support bar that can be raised and lowered horizontally and that can support the lower end of a vertically erected transformer material or floor material at a predetermined height, and a pair of support bars that can extend and retract upward from each holding device main body a first slide bar;
A pair of rollers are arranged at the tips of second slide bars that are moved diagonally upward from the upper ends of each first slide bar to sandwich the transformer material or floor material from both sides at a predetermined position. It is. Therefore, the transformer material or the floor material can be held upright so that its upper end surface is at a predetermined height, and welding can be easily automated.

Hereinafter, one embodiment of the present invention will be described based on the drawings. 1 to 5, reference numeral 1 denotes a cart that can move in the left-right direction (hereinafter referred to as "lateral direction") in FIG. Rails 2 are laid in the direction (hereinafter referred to as the "vertical direction"). 3 is rail 2
It is a cart that can be moved vertically on its upper surface, and a groove 4 whose bottom is wider than the opening is formed in the horizontal direction on its upper surface. 5 is a rack placed on the bottom of the groove.

On the truck 3, a pair of holding device main bodies 8 are provided, each having a convex portion 6 that is slidably fitted into the groove 4, and a pinion 7 that is built into the convex portion 6 and meshed with the rack 5.
is provided. A threaded rod 12 is provided on both sides of each main body 8 and is supported in the vertical direction by bearings 9 and 10 and is rotationally driven by a motor 11. Each threaded rod 12 has a nut 13 and 14, respectively. They are screwed together. Opposing nuts 13 and 14
A support bar 15, which is fixed to one nut 13 and slidably passes through the other nut 14, extends horizontally between them.

Fitted into the main body 8 are first slide bars 19 each having a rack 18 that meshes with a pinion 17 driven by a motor 16 attached to the main body 8, and is extendable and retractable upward from the main body 8. ing. A motor 21 with a pinion 20 attached thereto is fixed to the upper end of the slide bar 19, and a frame-shaped slide bar guide 22 that is inclined obliquely upward toward the center of the truck 3 is fixed. The slide bar guide 22 is provided with a rack 23 that engages with the pinion 20, and is penetrated by a second slide bar 25 having a roller 24 freely rotatable at its tip.

In addition, 26 is a pair of automatic welding devices arranged on the sides of the trolley 3 on the trolley 1, and a vertical rail 28 provided on a support 27 erected from the trolley 1, and this rail 28. a moving platform 30 movable on the top and having lateral rails 29;
, a vertical hydraulic cylinder device 31 that is movable on a rail 29, and a welding torch 33 that is swingably pinned to the tip of an arm 32 that is raised and lowered by the hydraulic cylinder device 31. .

In the above configuration, when holding the floor material 35 having the small brackets 34 as shown in FIG. 4, for example, the cart 1 is moved in accordance with the spacing of the floor materials 35 to be arranged in a predetermined position, that is, in a double row. At the same time, the cart 3 is moved to a position where interference with the small bracket 34 does not occur, that is, according to the longitudinal interval. Next, the pinion 7 and the motor 21 are driven to open the holding device bodies 8 to a predetermined distance and to separate the opposing rollers 24 from each other. After that, the floor material 3 is placed on the support bar 15.
5 is placed on the floor material 35, and the motor 11 is driven to raise and lower the support bar 15, thereby adjusting the upper end surface of the floor material 35 to a predetermined height. At the same time, the motor 16 is driven to adjust the slide bar 19 to a predetermined height, and the motor 21 is driven to bring the rollers 24 closer to each other so that the upper edge of the floor material 35 is sandwiched and positioned and held. .

Figure 5 shows the frame portion 36 and large bracket 37.
This figure shows a case in which a transformer material 38 having a shape is held. At this time, after moving the carts 1 and 3 to a predetermined position, it is sufficient to open the two holding device bodies 8 in accordance with the width of the fence portion 36 and to separate the opposing rollers 24 from each other. This is the same as in Figure 4.

Transformer material 3 whose upper ends are aligned in this way
8 or floor materials 35 arranged in double rows, and by welding them together using the automatic welding device 26, the above-mentioned ship side panel block or ship bottom panel block is assembled.

As described above, according to the present invention, the lower part of the transformer material or floor material is held by the holding device bodies that can approach and separate from each other, and the upper part is held by the rollers, so that it is possible to Even if the transformer material or floor material is attached, this part can be held between the main body of the holding device, and the transformer material or floor material can be stably held in two places, upper and lower. Furthermore, since the roller can be moved vertically by the first slide bar, even if the transformer material or floor material is high, the upper and lower parts can be held in two places, the roller and the holding device main body, depending on the height. Its stability is not compromised. Furthermore, since the cart on which the holding device body is placed can be moved in the longitudinal direction along the length of the transformer material or floor material, even if members such as brackets are fixed to the transformer material or floor material, It is possible to select a location where the parts can be held stably by moving the cart while avoiding the members. In this way, the transformer material or floor material can be accommodated as appropriate and the upper end surface can be held upright at a predetermined height, making it easy to automate welding and automate the assembly of panel blocks. can be achieved.
