Description

[Detailed description of the invention] This invention relates to a device used as a method of assembling a frame applied as a reinforcing member of a ship's hull, that is, a block made of longitudinal material and tranos material, and its purpose is to form a single conveyor line. To provide a device for simultaneously inserting a required number of lodge materials from the sides of the line into slits of transformer materials arranged side by side on a surface plate that is fed along the line.

The framework of the ship block has slits formed at a predetermined pitch, a large number of transformer materials arranged side by side at regular intervals, and a large number of longitudinal tubes that are inserted into the slits of each of the transformer materials. It has a structure in which the members are combined in a cross-shaped structure, and both of the above-mentioned members are supplied as a strong integral structure that is welded together.

By the way, in the past, longitudinal members were placed and welded on a skin plate welded to a predetermined size, and then the transformer members were lifted one by one using a crane, and the longitudinal members were inserted into the slits provided in the lance members. Insert the longitudinal material, join the side of the longitudinal material to one side edge of the transformer material, and then press the color plate 1 on the slit to weld the joints at multiple locations, or However, even if the transformer materials are placed upright at predetermined intervals and held firmly,
After that, a longitudinal material is inserted from one side and tack welding is carried out, and the thus assembled framework is carried out and placed on the skin flue 1, and the skin is attached. The so-called framework construction method was adopted.

However, the former method requires a large number of color plates and increases the amount of welding work, while the latter has equipment constraints on the longitudinal space, and in both cases, longitudinal materials are lifted and inserted one by one. There are drawbacks such as being forced to perform complicated and inefficient work, and it is difficult to expect a reduction in production costs based on the intensive equipment layout of assembly lines in factories.

The present invention has been devised for the purpose of providing a further improved device in view of the above-mentioned circumstances, and will be explained below based on the drawings showing one embodiment thereof.

In other words, the present invention is capable of inserting rows of longitudinal materials arranged corresponding to the slit intervals of the transformer material from the side of the transformer material arranged and held on the surface plate or skin plate L that is fed along the conveyor line. - This relates to a device for inserting objects from the side edge first, and inserting the objects from the side edge sequentially and in a batch operation. In the drawing, A represents one conveyor line installed in the factory. The transformer materials A are guided and fed by B, and the transformer materials A are arrayed and held on a surface plate or arrayed and fixed on a skin plate, in which case each transformer material is provided with The slit (longue material insertion hole) is horizontal.
It matches the straight line -L.

Note that the transformer material A is precisely positioned with respect to the row of longitudinal materials inserted from the side thereof, and a surface plate stopping mechanism for this purpose is installed at an appropriate position on the line.

By the way, as explained earlier, the present invention is a device that inserts a row of longitudinal materials on the side of the transformer material A at right angles to the above-mentioned I-lance material A in one operation, and the bottom of the tank is
A rail 1 laid at right angles to the transformer material transfer conveyor line B and relatively parallel to it, a traveling truck 2 that moves forward and backward guided by the rail 1, and both ends held at the tip of the traveling truck 2, Furthermore, the bottom of the tank is equipped with a single pusher 3 whose inclination can be freely changed according to changes in the relative position of both traveling carts 2, and a longitudinal material holding and guiding mechanism 4 disposed between the rails 1. has been done.

Each of the traveling carts 2 guided by the rails 1 is provided with a self-propelling function, and in the embodiment, a drive mechanism 5 including a motor and a speed reducer is mounted on each cart 2. Consideration has been incorporated to transmit that rotation to the wheels.

Note that the means for the self-propelled trolley function may be any other means that utilize a chain drive system or a related mechanism of gears and racks, and the selection thereof is free.

Also, the pusher 3 has a long hole 6 at one end, as shown in the drawing, for example.
Attach a connecting fitting 7 having a structure, and connect this to the tip of one of the traveling trucks 2 via a pin connecting mechanism 8, and connect the other end to the tip of the other traveling truck 2 with a rotatable hinge mechanism 9. By doing this, when there is a change in the relative position between the traveling carriages 2, the inclination can be changed in response to the change without hindrance to the movement of the traveling carriages 2.

This pusher 3 comes into contact with the rear end of the row of longitudinal materials and has the role of pushing all the longitudinal materials toward the transformer material A. The things on the sides are placed first.

The longitudinal material holding and guiding mechanism 4 is arranged in multiple rows between the rails 1, and its partial structure is as shown in FIGS.
The guide roller 12 is rotatably supported on a base plate 11 fixed thereon, and a pair of holding metal fittings 13 are disposed directly above the center of the guide roller 12 to support the longitudinal material. A large number of bottomed objects are arranged on the underframe 10 at regular intervals.

That is, this arrangement interval matches the interval of the slits provided in the transformer material.

The base plate 11 on which the guide roller 12 and the holding hardware 13 are mounted and fixed is fixed using bolts so that the position can be adjusted with respect to the base frame 10, and this hole I is made into a long hole. Consideration should be taken into consideration, such as keeping the

The present invention has a structure as described in the embodiments above, and first, with the traveling cart 2 being moved backward, the longitudinal materials are placed and arranged on each guide roller 12 of the longitudinal material holding and guiding mechanism 4 to prepare for work. Take.

After the transfer and fixation of the transformer material A is completed, one of the traveling carts 2 is moved in advance by a small amount to give the pusher 3 a required inclination.
After that, the circular traveling trolley 2 is moved equally forward, and the above-mentioned pusher 3 sequentially pushes the longitudinal materials from the side toward the transformer material, and finally the entire row of longitudinal materials is inserted into the slit of the transformer material A at once. do.

Then, when the preceding lateral longitudinal material reaches the insertion end position, the preceding traveling cart 2 is stopped, and from then on, only one of the traveling carts 2 is operated to eliminate the inclination of the pusher 3 while applying a predetermined amount to all the longitudinal materials. It gives the insertion of

In addition, when it is necessary to correct the final insertion amount, when the pusher 3 is held perpendicular to the rail 1, in other words, when the rear end of the longitudinal material row is parallel to the transformer material A, further The purpose is distantly related by making the traveling carts 2 advance by the same amount at the same time.

The present invention consists of a transformer material transfer conveyor B that transports transformer materials arranged in a predetermined posture on a skin plate, and mutually parallel conveyors placed on the sides of this conveyor B at right angles to it. A pair of rails 1, 1, and each of these rails 1.1-)- are provided with a pair of running carts 2, 2 that move forward and backward along the rails, and at the tips of the pair of running carts 2, 2. A pair of pushers 3 are horizontally rotatable between the two through hinge mechanisms 8 and 9 provided on each of the rails, and each of the pair of rails 1 is

Underframe 10 for changing the position of the direction
Since the longitudinal material holding/guiding mechanism 4 placed on the top of the transformer material holding/guiding mechanism 4 is placed at the front and rear in the pushing direction, the longitudinal material to be inserted into the transformer material slit on the transformer material transfer conveyor B is The longitudinal material can be easily supported and held in an insertion posture corresponding to each slit by the horizontally variable holding hardware of the longitudinal material holding and guiding mechanism 4, and each longitudinal material can be held at the front end of the pair of traveling carts. By pushing, it is possible to insert each longitudinal material one by one by pushing the ends of each longitudinal material in a diagonal straight line integrally at a desired pushing angle, for example, so that the insertion is smooth and smooth. It can be done easily.

Also, since it is inserted from the side to the conveyor line,
It also greatly contributes to the intensive simplification of assembly equipment without sacrificing the effective space of the conveyor.

Furthermore, with the present invention, even if the tip of the longitudinal material comes into contact with the transformer material, the wheels of the traveling trolley will simply slip, and there will be no accident of the transformer material falling over. There will be no overload.

Furthermore, if it is desired to increase the thrust of the trolley when inserting an extremely large longitudinal material, this can be done simply by loading Way I on the trolley.
