Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a top guide attached to a belt conveyor or other horizontal conveyance device.

(Prior Art) A lifting device for a top guide of a conventional conveying device is mounted on a support frame provided within a range that allows for the deflection of the top guide, and the mounting positions of the top guides are changed. Furthermore, a device was known in which the heights of the upper guide rail, chain, and push rod were adjusted (Utility Model Publication No. 36411/1983).

(Issues to be solved by invention) According to the conventional fixed guide installation method, when conveying articles of different heights, each installation point must be manually adjusted, especially in places where there are many adjustment points. Not only does this require a lot of time and effort, but there is also the problem that transport must be interrupted during the adjustment period. In addition, there was a problem in that errors in the adjustment height were likely to occur because the height was adjusted individually.

Next, although the heights of the guide rail, chain, and push rod can be adjusted simultaneously according to the above-mentioned known device, in order to achieve this, the entire structure must be constructed using a frame, which makes the device large and complicated. I came across a problem.

(Means to solve the problem) However, in this invention, the top guide is suspended from a sliding rod with the same length as the top guide, and the sliding rod is operated in parallel to automatically raise and lower the top guide steplessly. As a result, all of the problems of the conventional technology have been solved. In addition, the structure is simple and the operation is accurate.

That is, this invention connects the lower end of a hanging member to multiple locations of a guide member placed parallel to the upper side of the conveyor, and in order to raise and lower the hanging member, the other end is connected to a guide installed on a supporting frame. Through a ring, it is connected to a sliding rod that is slidably installed above and parallel to the guide member, and is connected to a hydraulic cylinder so that the sliding rod can slide in a direction parallel to the guide member. This is a top guide adjustment device in a conveying device made of The hanging member may be a plastic chain, a rope, or a support rod.

(Function) According to this invention, since the hanging member of the top guide is connected to the sliding rod to raise and lower, the top guide can be adjusted steplessly to a predetermined height. Furthermore, by installing the sliding rod so as to slide in parallel and connecting it to the fluid pressure cylinder, the hanging member of the top guide can be easily raised and lowered.

(Example 1) Next, an example of this invention will be described with reference to FIGS. 1 to 5.

A guide rod 2 (guide member) is suspended by one end of a plastic chain 3 (suspension member) above a belt conveyor 1 installed substantially horizontally so as to face each other in parallel. The other ends of the plastic chains 3, 3 are connected to a sliding rod 6 via a connecting bolt 7 via guide wheels 5, 5 of support frames 4, 4, respectively. The sliding rod 6 is fixed to a piston rod 10 of an air cylinder 9 (hydraulic cylinder) on a table 8 via a protrusion 11.

In the embodiment described above, if pressurized air is supplied to the base end side of the air cylinder 9 (FIG. 1), the piston rod 10 is pushed out in the direction of the arrow 12.
The sliding rod 6 also slides in the direction of arrow 13, and the guide rod 2 rises as shown by arrow 14. Next, when pressurized air is supplied to the tip side of the air cylinder 9, the piston rod 10 is retracted in the direction of the arrow 15, the sliding rod 6 also slides in the direction of the arrow 16, and the guide rod 2 is moved in the direction of the arrow 15. It descends like 17. As described above, the height of the guide rod 2 can be adjusted steplessly by supplying pressurized air.

(Effect of the invention) That is, according to this invention, the hanging member is connected to multiple locations of the guide member provided above the conveyor, and the lifting input member is connected to the hanging member, so that the guide member can be moved steplessly. , and can be adjusted very easily, and the adjustment can also be effected while the conveyor is in use. Therefore, the height accuracy of the guide member can be kept high. In addition, the overall structure is simple, and each adjustment member is lightweight and can be adjusted easily and easily.
