Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a framing device for bar-shaped products such as coated welding rods.

[Conventional technology]

In the production of coated welding rods, a coating agent (flux) is applied to the core wire using a coating machine, the ends of the thus obtained coated welding rods are processed, and the coated welding rods are received in predetermined numbers on a frame ( It is common to go through the following steps: frame cutting), drying and firing in a furnace.

FIG. 3 shows an outline of the framing process, and 10 (subscripts a and b are used to distinguish each other and will be omitted in the explanation as appropriate) is a parallel conveyor type conveyor, on which a large number of covered welding rods 12 are carried. Each book is stacked in blocks with gaps between them (with larger gaps between blocks). A magnet is effective in creating a small gap between the covered welding rods 12, and when magnetized by the magnet, the covered welding rods repel each other so that they have approximately the same small gap between them. Blocking can be carried out by a method such as pressing a conveyor having chevron-shaped protrusions at regular intervals from below the covered welding rod on the conveyor. A large number of cross-shaped frames 14 for frame removal are piled up and transported in two piles. Then, one by one, starting from the upper tier, they are carried directly below the conveyor 10 by a conveyor with hooks. The frame support member 18 is located at this position (frame removal position), and when the two blocks of the welding rod 12 come directly above the frames 14a and 14b, the conveyor 10 stops and the frame support member 18 starts to rise due to the cam. . When the frame support member 18 rises, the frame 14
a, 14b are pushed up to receive the welding rod block on the conveyor 10, and are then gripped by the frame holding claws 24 of the traverse head 22. Although the traverse head 22 is shown shifted to the right in FIG. 3, it is actually located directly above the framing position (particularly the claw 24 portion).

The traverse head 22 reciprocates in the direction of arrow _F1 , and there is a magnetic table (not shown) in the moving range of the traverse head that keeps the welding rod spacing constant, and eventually the welding rod is moved together with the frame onto the carriage. When a predetermined number of welding rod storage frames are loaded, the truck starts traveling and charges these into a drying/firing furnace.

The frame support member 18 is raised and lowered by a mechanism shown in FIG. A base 32 slidably supports the stabilizing rods 30a and 30b, thereby supporting the frame receiving member 18 and guiding it up and down. Double-shaped lever 28
a and 28b, one end of which is pivotally connected to a rod 26 that abuts the cam 20, and the other end is pivotally connected to the frame receiving member 18 via a connecting piece. Therefore, when the cam 20 rotates and the rod 26 reciprocates, the frame receiving member 18 moves up and down, and its tip engages the frames 14a, 1.
4b is pushed up so that the welding rod blocks on the conveyor 10 are received by these frames.

[Problem that the invention attempts to solve]

The coated welding rod that is framed has only been pre-dried after painting and is easily damaged. As the frame removal process is followed, the welding rod block is fed onto the frames 14a and 14b, and the frame receiving member 18 is raised to remove the frame 14.
a, 14b are pushed up, and as a result, the welding rod on the conveyor 10 first transfers to the frames 14a, 14b, and then rises while remaining on these frames,
The frames 14a and 14b stop slightly above the claws of the frame holding claws 24a, and then the frame receiving member 18 begins to descend.
4b is hooked with the claw, the lowering is stopped, and only the frame receiving member 18 is lowered. However, when the frame is transferred onto the frame of , and when the frame is received by the frame holding claw, a shock is applied. The coated welding rod is easily damaged. The inventors first proposed a method to improve the speed by adjusting the speed. Therefore, the present invention aims to improve this point and prevent the coated welding rod from being damaged as much as possible.

[Means for solving problems]

This invention receives a large number of block-shaped bar-shaped products conveyed by a parallel conveyor into a frame that is placed on an ascending frame receiving member and pushed up from between the parallel conveyors, and then raises the frame. In a frame removing device for bar-shaped products that is fixed to frame holding claws of a traverse head, pedestals are attached to the frame receiving member at positions corresponding to both outside sides of the parallel conveyor, and the bar-shaped products of the frame are attached to these pedestals at positions corresponding to both outside sides of the parallel conveyor. It is characterized by having an elastic cushioning material attached so that the surface is slightly higher than the product receiving surface.

[Function] If pedestals are provided on the frame receiving member at positions corresponding to both outside sides of the parallel conveyor, and elastic cushioning material is attached to these pedestals so that the surface is slightly higher than the rod-shaped product receiving surface of the frame, the parallel conveyor The upper bar-shaped product first comes into contact with the elastic cushioning material, and as the cushioning material is recessed, it is received by the bar-shaped product receiving surface of the frame, and if the recess is not sufficient, the frame is locked with the frame holding claw of the traverse head. When the frame receiving member descends, it is received by the bar-shaped product receiving surface of the frame, and this is done very softly, so that the bar-shaped product will not be damaged.

〔Example〕

FIG. 1 shows an embodiment of the present invention. The same parts as in FIG. 3 are given the same reference numerals. In the present invention, the frame receiving member 18 has a pair of pedestals 26a, 26b and 26.
c and 26d are provided, and an elastic cushioning material 28 is attached to the surfaces of these pedestals. Figure 2 shows details of this part. Pedestals 26c, 26d (26a, 26b
(same as above) are located on both outer sides of the parallel conveyors 10a, 10b, and the surface of the elastic cushioning material 28 is made to be higher than the bar-shaped product receiving surface 14A of the frame 14 by δ. Therefore, the frame receiving member 18 rises, and the conveyor 1
When receiving the bar-shaped product 12 on the frame 14 into the frame 14, the bar-shaped product 12 first hits the cushioning material 28, and the cushioning material is recessed to come into contact with the bar-shaped product receiving surface 14A of the frame 14. When the cushioning material 28 cannot be completely recessed, the bar-shaped product 12 is received by the cushioning material 28, and when the frame receiving member 18 descends to engage the frame holding claws 24 of the traverse head 22, the rod-like product 12 is received by the receiving surface 14A. come into contact with In either case, the rod-shaped product 12 makes very soft contact with the receiving surface 14A.

In FIG. 1, reference numeral 16 denotes a conveyor with a hook, and a hook 30 receives the topmost frame 14 stacked in a pile and conveys it to a frame picking position. At this time, the frame receiving member 18 is in the lowered position, and the frame being carried will not collide with the pedestal 26 or the like. After the frame is transported to the frame removal position, the frame support member 18 is raised to the state shown in FIG. 2. The conveyor 16 reciprocates, and when the frame is received by the frame receiving member 18, it retreats and prepares for carrying in the next frame. When retreating, the claw 30 passes over the tip of the pedestal 26.

As the elastic cushioning material 28, sponge, felt, etc. are used. A suitable height difference δ is 2 to 3 mm.

[Effect of idea]

As explained above, according to the present invention, damage to rod-shaped products during framing can be reduced, and the yield of products such as coated welding rods can be improved, which is extremely effective.
