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 slide bar is provided so as to be rotatable around an axis arranged at the upper end of each slide bar in a horizontal state in the vertical direction, and by this rotation, the transformer material or floor material is moved from both sides at a predetermined position. It has a pair of eccentric rollers that are held in place. 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 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. At the upper end of the slide bar 19, a shaft 21 is fixed to each pair of two eccentric rollers 20a, 20b.
are supported vertically and horizontally. 22 is a motor for rotating the shaft 21 via a gear device 23.

In addition, 24 is a pair of automatic welding devices arranged on the sides of the trolley 3 on the trolley 1, and a vertical rail 26 provided on a support 25 erected from the trolley 1; a moving platform 28 movable on top and having lateral rails 27;
, a vertical hydraulic cylinder device 29 movable on a rail 27, and a welding torch 31 swingably pinned to the tip of an arm 30 that is raised and lowered by the hydraulic cylinder device 29. .

In the above configuration, when holding the floor material 33 having the small brackets 32 as shown in FIG. 4, for example, the cart 1 is moved to a predetermined position, that is, in accordance with the spacing of the floor materials 33 to be arranged in double rows. At the same time, the carriage 3 is moved to a position where no interference with the small bracket 32 occurs, that is, according to the longitudinal interval. Next, the pinion 7 and the motor 22 are driven to open a predetermined gap between the two holding device bodies 8, and the opposing eccentric rollers 20a, 2
0b are separated from each other. After that, the support bar 15
The floor material 33 is placed on top, and the upper end surface of the floor material 33 is adjusted to a predetermined height by driving the motor 11 to raise and lower the support bar 15.
At the same time, the motor 16 is driven to adjust the slide bar 19 to a predetermined height, and the motor 22 is driven to rotate the eccentric rollers 20a, 20b, and position the floor material 33 by pinching the upper edge of the material 33. and hold.

Figure 5 shows the face section 34 and large bracket 35.
This figure shows a case in which a transformer material 36 having a shape is held. At this time, after moving the carts 1 and 3 to predetermined positions, it is sufficient to open the space between the two holding device bodies 8 in accordance with the width of the frame portion 34 and to separate the opposing eccentric rollers 20a and 20b from each other. The effect is the same as in FIG.

Transformer material 3 whose upper ends are aligned in this way
By placing the skin material on the double rows of floor materials 33 and welding them together using the automatic welding device 24, 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 body that can approach and separate from each other, and the upper part is held by the eccentric roller, so that Even if a member is attached, this part can be held by the main body of the holding device, and the transformer material or floor material can be stably held at two locations, upper and lower. In addition, the eccentric roller can be moved vertically by a slide bar, so even if the transformer material or floor material is high, the upper and lower parts can be held in two places, the eccentric roller and the holding device main body, depending on the height. 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.
