Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aggregate for temporary welding by arranging aggregates such as strips and reinforcing ribs at predetermined positions on a skin material in a welding line for manufacturing ship blocks and bridge blocks. Regarding temporary equipment.

[0002]

2. Description of the Related Art An aggregate temporary tacking robot that has been conventionally used in a welding line for manufacturing boat blocks, bridge blocks, etc. is laid on both sides of the welding line 21 as shown in FIG. 2, for example. A gate-shaped carriage 23 that can travel on a pair of transport rails 22 is provided, and a traversing carriage 25 that is movable by being guided by a traverse rail 24 installed on a horizontal frame 23a of the gate-shaped carriage 23 is mounted on a traverse carriage 25 via an elevating arm 26. The support beam 27 is rotatably attached to the support beam 2
7, a transfer robot hand 29 equipped with a temporary welding machine 28 is provided so as to freely approach and separate. As a result, the welding line 2
The aggregate 31 on the aggregate pallet 30 arranged in No. 1 is gripped, conveyed to a predetermined position on the skin plate 32 arranged on the welding line 21, positioned, and temporarily welded by the welding machine 28.

[0003]

However, in the above welding member mounting robot, (1) it is necessary to arrange the aggregate pallet 30 on the welding line 21, so that the flow of the welding line 21 is hindered. Subject to great restrictions. (2)
Aggregate 31 within welding line 21 via aggregate pallet 30
Therefore, the welding line 21 is widely occupied, and waste occurs in the transfer operation of the robot. (3) When the aggregate 31 is a long strip, when the central portion is gripped by the transport robot hand 29, the aggregate 31 bends due to its own weight, and the skin plate 3
There was a problem that it was difficult to position it on the second position at an accurate position.

The present invention solves the above-mentioned problems, is not restricted by the flow of the welding line, is not wasteful in the operation, and is capable of accurately positioning and performing temporary welding even with a long aggregate. An object is to provide an aggregate temporary attachment facility for a welding line that can be used.

[0005]

In order to solve the above problems, the welding member mounting equipment in the welding line of the present invention is
A gate-type cart equipped with two aggregate temporary tacking devices that can travel freely on a traveling rail laid along a welding line, and the aggregate temporary tacking device can travel on the traveling rail, and the gate. A traversing carriage that is placed on a dolly and is movable in a direction orthogonal to the welding line, a swinging arm that is swingably mounted on the traversing carriage around a vertical axis, and a lifting arm that hangs up and down at the tip of the swinging arm. The gripping device is provided so as to be rotatable about a vertical axis through the lifting column, and is capable of gripping the aggregate, and a welding device provided in the gripping device.

[0006]

According to the above structure, the traverse arm is moved to the end side of the gate type carriage and pivoted to the outside of the welding line so that the aggregate arranged outside the welding line can be grasped. . Therefore, it is not necessary to dispose the aggregate pallet in the welding line as in the conventional case, and since the aggregate pallet does not occupy the welding line widely, the flow of the welding line is not restricted and the efficiency is high. Welding work can be performed, and by arranging the aggregate pallets on both sides of the welding line, useless operations of the gate type carriage are reduced. Furthermore, the long aggregates are held by the two gripping devices of the temporary attachment device respectively for the joint work, so that the aggregates can be accurately positioned with little bending.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the aggregate temporary attachment facility according to the present invention will be described below with reference to FIG. A pair of traveling rails 3 are laid along both sides of a welding line 2 that conveys the skin material 1 by a roller conveyor device (not shown).
Two movable aggregate tacking devices 4 are arranged on the traveling rail 3.

This aggregate temporary tacking device 4 is provided with a gate type carriage 5 arranged over the left and right traveling rails 3, and the gate type carriage 5 is provided.
At the lower end of the leg portion 5a, there is provided a drive carriage portion 5b for causing the gate-type carriage 5 to travel in the welding line 2 direction. On the horizontal beam 5c of the gate-shaped carriage 5, a horizontal carriage 6 which is movable along the horizontal beam 5c in a direction orthogonal to the welding line 2 is arranged. On the horizontal carriage 6, a swing arm 7 projecting horizontally is provided. It is arranged to be rotatable around a vertical axis through a swivel base 7a. An elevating column 8 is attached to the tip of the revolving arm 7 so as to be vertically movable, and at the lower end of the elevating column 8, an aggregate, such as a garter 9, is attached to a rotary table 11 that is rotatable around a vertical axis. A gripping device 10 provided with a pair of fingers 10a capable of gripping the above is provided. Further, a welding device 12 for temporarily attaching the garter 9 to the skin material 1 is provided on the rotary base 11 via an articulated arm.

The temporary tacking work of the aggregate having the above structure will be described. For short aggregates, each aggregate temporary tacking device 4 is driven. That is, the traverse trolley 6 is moved to the end side of the gate-type trolley 5, the revolving arm 7 is revolvingly moved to the outside of the welding line 2 to lower the elevating support column 8, and the aggregate arranged on the outer side of the traveling rail 3 is moved. Aggregate 1 from above pallet 13
4 is gripped and lifted, conveyed to a predetermined position of the skin material 1, and after positioning, temporarily attached by the welding device 12.

As for the garter 9 having a long length, the two aggregate temporary tacking devices 4 are cooperatively driven as shown by phantom lines. That is, each traverse trolley 6 is connected to each gate type trolley 5
Of the garter 91 on the aggregate pallet 13 is gripped by moving the swing arm 7 to the outside of the welding line 2 to lower the elevating support column 8. Then, the gate type carriage 5, the traverse carriage 6, the swing arm 7, the lifting column 8, and the rotary base 11 are cooperatively driven by the control device to lift the garter 9, and the garter 9 is conveyed to a predetermined position on the skin material 1, and after positioning. It is temporarily attached by the welding device 12. As a result, it is possible to accurately position even an aggregate that is long and easily bent.

[0011]

As described above, according to the present invention, the traverse trolley is moved to the end side of the gate type trolley to pivot the pivot arm to the outside of the welding line, thereby arranging the bone arranged outside the welding line. The material can be gripped. Therefore, it is not necessary to arrange the aggregate pallet in the welding line as in the conventional case, and the aggregate pallet does not occupy the welding line widely, so that the flow of the welding line is not restricted and the welding is efficiently performed. Work can be performed, and by arranging the aggregate pallets on both sides of the welding line, useless movement of the gate type carriage is reduced. Furthermore, by holding both ends of the long aggregate with the holding devices of the two tacking devices respectively and performing the joint work, the aggregate can be held with little bending and accurately positioned.
