JPH07323911A - Slide shoe in article sorting conveyor device - Google Patents

Abstract

PURPOSE:To prevent the brokenly falling accident of parts and to accurately form a conveyor device by providing a branch cam rail for sliding an article sorting slide shoe, and unitedly molding a slide guide block to compose, the slide shoe and an article sorting pusher. CONSTITUTION:In a sorting conveyor device, many shaft levers are arranged in parallel, and both their ends are severally connected to a driving conveyor chain travelling on a guide rail, and an article sorting slide shoe 10 being slidable along the shaft lever is provided. In this case, after a slide block 11 having a cavity 11A for inserting through the shaft lever is formed, a raw material for a pusher 12 is poured into the same metallic mold to unitedly mold the slide guide block 11 and the pusher 12 for forming the slide shoe 10. In addition, the attaching plate 14 of a bolt 13 for vertically providing a travel guide pin P is buriedly provided in a slide guide block 1, and a roller 15 rolling on a guide rail is attached to the guide pin P.

Description

Detailed Description of the Invention

[0001]

2. Description of the Related Art An article sorting conveyor device using slide shoes is disclosed in Japanese Patent Application Laid-Open No. 5-722.
That is, as shown in FIG. 1, the sorting conveyor device disclosed in the above publication has a large number of rods B arranged in parallel and both ends of which are connected to a drive conveyor chain C which travels on a guide rail. A slide pin S is provided which is slidable along these shaft rods, and each slide shoe is provided with a guide pin P projecting downward from the shaft rod B and traveling in a guide groove. A branch cam rail that guides and slides the article sorting slide shoe S along the shaft rod is provided branching from the guide groove, and the article A is slid to the right by the slide shoe S to the side of the branch conveyance path D. As shown in the front view of FIG. 4, the conventional slide shoe S divides the slide guide block 1 and the article A into the branch conveyance path D.
The slide guide block 1 is composed of a rubber article sorting pusher 2 and a base plate 3 that are moved in the direction.
The slide guide block 1 is sandwiched and clamped by sandwiching the mounting bolt 4, and the slide guide block 1 is assembled by sandwiching and clamping the slide guide block 1. Then, as shown in FIG. 5, a pair of rods B adjacent to the slide guide block 1 (see FIG. 1)
The concave fitting portions 1A, 1A for slidably holding the are formed.

[0002]

In the conventional slide shoe described above, since the slide guide block 1 is sandwiched and clamped with bolt nuts, the block 1 is compressed and deformed so that the concave curved surface of the concave fitting portion 1A is formed. There is a possibility that the slide shoe may not be able to slide smoothly along the axial rod B, and that the nut screwed to the bolt loosens during use and the slide shoe component is missing.

Further, the assembling work step of assembling the slide guide block 1, the pusher 2, and the base plate 3 and tightening them with bolts requires labor and time, and the dimensional accuracy of the respective members 1, 2 and 3 also varies. As a result, the dimensional accuracy of the slide shoe after assembling varies, and other product defects occur.

[0004]

In order to solve the above-mentioned problems of the prior art, the present invention is a slide shoe in which a slide block, a pusher and a base plate are separately molded and tightened and integrated by bolt nuts. Is formed by integrally forming the pusher portion and the slide guide block portion during molding.

[0005]

Since the pusher portion and the slide guide block portion are integrally molded, the assembly fastening bolt is not required, and therefore the shape of the concave fitting portion formed on the slide guide block is not distorted or deformed.

[0006]

FIG. 2 is a front view of a slide shoe 10, FIG.
3 is a side view of the shaft rod B. The cross-sectional shape of the shaft rod B is substantially circular in the conventional example shown in FIG. 5 and is rectangular in the present invention shown in FIG. After forming the cavity 11A through which the rod is slidably inserted to form the slide block 11, the pusher 12 is inserted into the same mold.
The slide shoe 10 is formed by injecting the above raw materials and integrally molding the slide guide block 11 and the pusher 12.

Since the slide guide block 11 slides on the aluminum rod, the slide guide block 11 has excellent abrasion resistance and sliding characteristics like thermoplastic polyamide resin, super-variable molecular weight polyethylene, polyacetal resin, and polyimide resin. Since the pusher 12 is selected from the materials and comes into contact with the articles when the articles A are sorted, the pusher 12 is made of a material having excellent impact absorption property such as thermoplastic elastomer resin, neoprene rubber, urethane rubber or the like so as not to give an impact to the articles. Selected from the inside.

The slide guide block 1 is formed by embedding a mounting plate 14 of a bolt 13 which vertically extends a running guide pin P of a slide shoe 10, and guides the guide pin P to the guide pin P in a guide groove. A roller 15 with a ball bearing that rolls on a guide rail is installed.

[0009]

According to the present invention, since the slide guide block and the pusher are integrally formed, a bolt for fastening them is not required. Therefore, the cavity 11 through which the shaft rod is inserted is provided.
Since there is no possibility that the shape of A will be distorted or compressed and deformed,
The bolts that smoothly slide through the shaft rod without any hindrance, and vertically suspend the guide pins that guide the travel of the slide shoe 10, are tightly held by the nuts on the mounting plate 14 embedded in the slide guide block at the time of molding. Since it does not affect the distortion or deformation of the cavity 11A of the slide guide block at all, the assembly work required for molding the conventional slide shoe is completely unnecessary, and there is no assembly part by integral molding. Therefore, there is no risk of accidental missing of parts during use, and the dimensional control of the slide shoe is easy to obtain with high precision by integral molding.
