The respective hook preventing pieces 23 provided in such a manner that their ends are located below a guide bar 18. That is, the ends of the hook preventing means 23 are provided up to the positions hidden by the guide bar 18.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a guide bar attachment for a conveyor.

[0002]

Disadvantages of the Prior Art A conventional guide bar attachment for a conveyor has a vertical portion (including vertical in this specification) which has a guide bar fixing member at its upper end. However, it is generally located at the crotch of a person in relation to the height of the conveyor, etc., and clothes of workers may be caught in this vertical portion, which is dangerous. Especially, it is connected to the conveyor base frame mounting part,
In the case where a vertical portion is provided at the tip of the horizontal portion of the outward protrusion, the drawback is great.

[0003]

[Means for Solving the Disadvantages] The present invention employs the following means in order to eliminate the above disadvantages. The present invention
At the front and rear edges of the vertical part that has a guide bar fixture at the upper end,
A catch prevention piece whose tip is directed toward the center of the conveyor is provided.

[0004]

The present invention has the following functions. The catch prevention piece can prevent workers' clothes and the like from being caught on the vertical portion of the guide bar attachment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments with reference to the drawings. In this specification, the front means the back side of FIG. 1, the rear means the front side, the left means the left side of FIG. 1, and the right means the right side of FIG.

A pair of left and right base frames 2 of the roller conveyor 1
The bearings 3 are provided at predetermined intervals in the front-rear direction so that the left and right bearings face each other. A carrier roller 5 is stopped in a recess 4 that is open above the bearing 3 and on the center side of the roller conveyor 1.
The carrier roller 5 includes a roller shaft 6 fixed to the carrier roller 5 and the roller shaft 6.
The roller main body 8 is fitted through a bearing (not shown).

A guide bar attachment 1 is attached to the left and right base frames 2.
1 are provided at predetermined intervals in the front-rear direction by the means described in detail below. The guide bar mounting tool 11 engages with a vertical lower conveyor base frame mounting portion 13 and an edge of a mounting groove 9 formed in the front-rear direction of the base frame 2 that is continuous with the lower end thereof. Part 12 and the conveyor base frame mounting part 13
A horizontal part 14 continuously provided at the upper end of the vertical part 15, a vertical part 15 continuously provided at the tip of the horizontal part 14, a horizontal part 16 continuously provided at the upper end of the vertical part 15, and a horizontal part 16 attached to the horizontal part 16. And the guide bar fixing tool 17 is provided. The engaging portion 12 is brought into contact with the upper edge of the mounting groove 9 of the base frame 2,
The guide bar fixture 11 can be fixed to the base frame 2 by screwing the bolt 20 through the through hole 19 formed in the conveyor base frame mounting portion 13 into the nut 21 fitted in the mounting groove 9 facing the bolt 20. I can. It should be noted here that if there is no engaging portion 12, the guide bar mounting tool 11 can swing back and forth around the bolt 20 with only one bolt 20.
This means that at least two bolts 20 are necessary. In this embodiment, the bolt 20 and the nut 21 are used to stop the engaging portion 12 in contact with the upper edge of the mounting groove 9. This is the point where fixing of the guide bar attachment 11 is completed with the bolt 20 of the book.

The guide bar 1 is attached to the guide bar fixture 17.
8 is attached.

At the front and rear edges of the vertical portion 15, there are provided catching prevention pieces 23 whose tips are directed toward the center side (the center side in the left-right direction) of the roller conveyor 1. The tips of these catching prevention pieces 23 are located below the guide bar 18, that is, the tips of the catching prevention pieces 23 are hidden by the guide bar 18 when seen in a plan view.

[0010]

[Modifications, etc.] Modifications will be described below. (1) FIGS. 4A to 4C show modified examples of the present invention. The guide bar attachment 11 shown in FIG. 4 (a) is provided at the curved corner portion of the roller conveyor 1, and the horizontal portion 14 extends outwardly for a considerable length of time. (2) The tip of the catching prevention piece 23 may not be located below the guide bar 18. (3) The conveyor is not limited to the roller conveyor 1 and may be a belt conveyor, a chain conveyor, or the like.

[0011]

The present invention has the following effects due to the above-described structure. According to the first aspect of the present invention, the catching prevention piece can prevent clothes or the like of the worker from being caught on the vertical portion of the guide bar attachment. According to the invention of claim 2, the tip of the catching prevention piece is positioned below the guide bar attached to the guide bar fixing tool, so that the worker's clothes or the like near the front and rear sides of the guide bar attaching tool. Since it is prevented from entering below the guide bar, it is possible to more reliably prevent workers' clothes and the like from being caught on the vertical portion of the guide bar attachment. According to the invention of claim 3, since the position of the guide bar mounting tool on the conveyor base frame is determined by bringing the engaging part into contact with the edge of the mounting groove of the conveyor base frame, the guide bar mounting tool can The guide bar fixture can be securely fixed to the conveyor base frame by simply fixing the points to the conveyor base frame with bolts or the like.
