Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a holding device for transformer material or floor material that positions and holds double rows of transformer material or floor material in a predetermined position.

For example, a ship side panel block can be manufactured by welding multiple transformer materials standing parallel to each other on a single skin material, or by sandwiching multiple floor materials parallel to each other between two skin materials. When producing a double-structured ship bottom panel block by welding, conventionally known panel block assembly methods include the ``loose material distribution method,'' ``frame assembly method,'' and ``line welding (longitudinal attachment). There are methods such as "Installing transformer material in bulk" and "(Pre-installation of transformer material) Longitudinal material all at once 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 trying to develop a new construction method that can easily automate the above, it is necessary to prepare the transformer material or floor material in advance so that their top surfaces are aligned so that the skin material can be attached, or to use a batch automatic handling device. It is advantageous if the welding parts are arranged and maintained in a predetermined shape for ease of use, as subsequent welding work becomes easier.

The present invention was developed with attention to this point, and includes a plurality of lower edge support devices that can be raised and lowered to place horizontally erected transformer materials or floor materials so that the upper end surface thereof is at a predetermined height. A pair of trolleys are provided which are movable on a pair of double track rails disposed on both sides of each row of the lower edge receiving device, and which are movable up and down and are movable up and down. A clamping jig for holding the material or floor material at predetermined positions on both sides thereof is provided on the cart, and a stopper is provided for locking one side end surface of the double row transformer material or floor material to respectively position the material. It is.

Therefore, for example, if the transformer materials or floor materials held in the double rows are collectively clamped by an automatic handling device and transported to an automatic welding machine, the transformer materials or floor materials can be reliably placed in the predetermined position of the automatic welding machine. This means that automation of the above-mentioned panel block production can be easily achieved.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In FIG. 1, reference numeral 1 denotes a lower edge receiving device which can be raised and lowered and which is provided on a board 2 in a plurality of linear rows. It is placed so that it is at the same height. Rails 4a and 4b are provided on both sides of each row of the receiving device 1.
A pair of carts 5a and 5b that are movable on a and 4b are respectively arranged. On these trolleys 5a and 5b, a clamping jig 6 is provided which can move in and out and up and down, and clamps the transformer material 3 at predetermined positions on both sides.
are arranged respectively. On the other hand, reference numeral 7 denotes a stopper provided on the substrate 2, which locks and positions the left end surface of each transformer material 3 in FIG. 1.

Details of the receiving device 1 are shown in FIGS. 2 and 3. A sheath body 8 is attached to the back surface of the board 2, and between the base board 2 and the sheath body 8, bearings 9a,
A nut 10 is rotatably held via 9b. Reference numeral 11 denotes a gear externally fitted onto the nut 10 so as to be able to rotate integrally therewith. This gear 11 has a motor 12
A gear 13 driven by is engaged with the gear. A receiver jig 16 having a receiver 14 at the upper part and a threaded part 15 at the lower part is screwed into the nut 10. Reference numeral 17 denotes a rotation prevention protrusion provided at the lower end of the threaded portion 15, and a vertical groove 18 provided in the sheath body 8.
is engaged with. FIG. 3 is a diagram showing a state in which the transformer material 3 held by the stopper 7 is supported by two receiving jigs 16.

The truck 5 and the pinching jig 6 disposed on the truck 5 will be described in detail with reference to FIGS. 4 to 6. That is, on the rail 4, there is a floating prevention roller 1.
A trolley 5 having a roller 9 and running rollers 20 is movably disposed on the rail 4. On the trolley 5, there are guide grooves 21 on both sides and racks 22 on both sides.
A box body 24 having a vertically elongated opening 23 on the side of the receiving device 1 is erected, and inside this box body 24,
A pinion 26 is engaged with the rack 22 and driven by the motor 25, a roller 27 contacts the guide groove 21, passes through the opening 23, and is moved in and out of the box body 24 by a hydraulic device 28. Pincer jig 6
An elevating body 29 is provided.

In the above configuration, when positioning and holding a plurality of transformer materials (or floor materials) 3 at predetermined positions, first select two of the receiving devices 1 in each row and drive the motor 12 to tighten the nuts. 10 to raise the receiving jig 16 to a predetermined height.
Next, move the trolley 5 to a predetermined position on the rail 4,
The motor 25 is driven to move the elevating body 29 to a predetermined position in the vertical direction, and the clamping jig 6 is set at a predetermined holding point.

Thereafter, the transformer material 3 is carried in each row using a lifting machine (not shown), and placed along the stopper 7 into the receiving device 1.
It is lowered upward and supported by this receiving device 1.
FIG. 3 shows this state, in which the transformer material 3 with its lower part recessed is placed in the receiving device so that its lower end does not contact the substrate 2 and its upper end is at a predetermined height. This is what is placed on 1. At this point, the hydraulic device 28 provided on the cart 5 is operated to push out the clamping jig 6, and the transformer material 3 is clamped and held from both sides thereof.

By repeating this operation for each row, the double rows of transformer members 3 are positioned and held in a predetermined arrangement as shown in FIG.

When the double-row transformer materials 3 in this state are to be clamped using an automatic handling device (not shown) and transported to an automatic welding machine, first, all the double-row transformer materials 3 are clamped at the same time using this automatic handling device, and then clamped. After detecting this by an appropriate means, the hydraulic device 28 is actuated to retract the clamping jig 6, so that it can be automatically carried out.

As described above, according to the present invention, not only can the upper surface heights of double rows of transformer materials or floor materials be made equal by the lower edge receiving device, but also the length of these double rows of transformer materials or floor materials can be adjusted by the stopper. In addition, the clamping jig on the trolley allows the transformer material or floor material to be held at any point along its length, making it possible to hold double rows of transformer material or floor material. , can be positioned and securely held at predetermined positions in the height and length directions.For example, transformer materials or floor materials held in double rows can be clamped all at once by an automatic handling device and transported to an automatic welding machine. This will ensure that this double-row transformer material or floor material is placed in a predetermined position on the automatic welding machine, and this double-row transformer material or floor material can be welded to the skin material to produce a panel block. In this case, skin attachment can be easily performed and automation of panel block production can be easily achieved.
