Abstract

PURPOSE:To shorten the working term, improving working safety and working accuracy by providing one set of conveying device with a welding machine, which can shift the upper part of a preparing stage for frame and the adjoining upper part of a base plate for assembling panel, and two sets of conveying device for the frame. CONSTITUTION:When the conveying device 8 with the welding machine comes on the base plate 6 for assembling the panel, fine adjustment is executed and a clamping device is descended and welding face in the frame 02 is press- contacted on a steel plate 01 prefixed to the base plate 6 for assembling panel. The automatic welding machine 10 in the conveying device 8 with the welding machine is descended near to the welding line in the steel plate 01 and each frame 02 is tack welded to the steel plate 01 along the welding line. When the automatic welding machine 10 reaches the welding running limit position in the welding line, only the conveying device 8 with the welding machine release the clamping device 9 and is shifted to the next tack welding position. By this method, as the frame is automatically tack welded on the steel plate without any man-labor at all, efficiency, labor safety and accuracy of the panel assembling work can be improved.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to automatic panel assembly equipment.

[Conventional technology]

For example, when building a ship, the rope temporary 01 in the initial assembly process
Conventionally, as shown in the perspective view of Fig. 2, the work of temporarily attaching the aggregate 02 by welding (hereinafter referred to as panel assembly work) is carried out by a worker 03 who takes out the aggregate 02 from the barresoto 04 with a crane 05 and places it on a surface plate. After positioning the upper steel plate 06 at a predetermined position using a crimping jig 07 or the like, the aggregate 02 is temporarily welded to the steel plate Ol.

However, such means have the following drawbacks.

(1) The pre-processes of panel assembly work, such as joining the steel plates 01 and cutting the aggregate 02, and the post-process, the actual welding of the aggregate 02 to the steel plate 01, are increasingly automated, but the panel assembly work itself is Since the weight of the aggregate 020 is large and the positioning accuracy is strict, it is still a manual process, which is a bottleneck in the initial assembly process.

(2) Aggregate 02 is heavy and its posture during positioning is unstable, so panel assembly work is not only labor intensive but also dangerous work. (3) Since the finish of panel assembly work varies from person to person, the accuracy of the work is unstable.

[Problem to be solved by the invention]

The present invention was proposed in view of these circumstances, and
The purpose of the present invention is to provide an automatic panel assembly device that can attach aggregate to steel plates by automatic tack welding and is excellent in shortening construction time, work safety, and work accuracy.

[Means to solve the problem]

To this end, the present invention provides a panel assembly apparatus for temporarily welding a plurality of aggregates onto a substantially horizontal steel plate in parallel, including an aggregate preparation stage having a jig that supports the plurality of aggregates in parallel to each other; A transport device with a welding machine capable of moving above the aggregate preparation stage and above the panel assembly surface plate adjacent thereto, and having multiple aggregate clamping mechanisms with lifting and lowering functions, and a plurality of automatic welding machines; Two conveyance devices capable of moving above the aggregate preparation stage and above the panel assembly surface plate while interlocking with a conveyance device equipped with a welding machine, and each having an aggregate clamping mechanism with a plurality of lifting and lowering functions. It is characterized by

With the above-mentioned structure, the aggregate can be attached to the steel plate by automatic tack welding, which shortens the construction period. An automatic panel assembly device with excellent work safety and work accuracy can be obtained. [Example] An example in which the present invention is applied to hull panel assembly will be explained with reference to the drawings. The same reference numerals as in Fig. 2 indicate the same members as in the same figure, and in the perspective view of Fig. 1, ■ The aggregate stage 3 is equipped with an overhead crane 2 for transporting aggregates that can move in the front-rear direction and the left-right direction.

Reference numeral 19 denotes a clamp device and a clamp lifting device attached to the conveyor devices 16 and 17, respectively. In such a device, in order to assemble each aggregate 02 to a steel temporary 01 by temporary welding, first the aggregate 02 is automatically cut on an aggregate cutting surface plate (not shown) and transported to an aggregate preparation stage via an overhead crane 2. 1 respectively on the aggregate construction jig 4,

By repeating such operations, for example, in this embodiment, seven aggregates 02 can be temporarily welded to the steel plate 01 at the same time. In addition, the conveyance devices 16 and 17 are adapted to move appropriately to the left in conjunction with the movement of the welding machine-equipped conveyance device 8 to the left as welding progresses, so as not to interfere with the welding progress. This can be done fully or semi-automatically by operating switches on the control panel 14.
