Description

[Detailed Description of the Invention] The present invention relates to a suspension conveyance device that suspends and conveys a load.

For example, when cultivating strawberries in a plastic greenhouse, a hanging conveyance device may be provided as a means for conveying the picked strawberries to the entrance of the greenhouse.

Such a suspended conveyance device requires virtually no installation space, and can achieve its intended purpose by simply stretching a rope or the like endlessly along the ceiling surface. A hanging member formed in an inverted J shape is suspended from the rope to prevent interference between the hanging member and the rope guide.

However, in all of these conventional systems, the rope, etc. that supports the hanging member is supported by a single guide roller, so if an unbalanced load is applied to the hanging member, the rope will move around the guide roller. There was a possibility that it would come off.

The present invention has been developed in view of the above, and employs a belt as a conveying body, and has both side edges of the belt rollingly engaged with guide rollers, and a suspension passing through a space formed between the guide rollers. By suspending and connecting the load to the center of the belt via the lower member, it is possible to prevent the belt from slipping off even if an unbalanced load is applied.

The present invention will be described below with reference to illustrated embodiments.

In the example, the present invention is applied to an opening/closing drive means for the inner layer sheet material of a multilayer vinyl house, and the outermost layer sheet material (not shown) is suspended along the inner surface of the main frame 1 that supports the stretched sheet material. By disposing the lower conveying device A, the main frame 1
The sheet materials 4 and 5 are configured to be able to be opened and closed by sliding along the sub-frames 2 and 3 constructed inside the.

Here, the hanging conveyance device A is composed of a guide 7 attached to each corner of the main frame 1 via a bracket 6, and a conveyance belt 8 held in an endless manner by the guide 7. ing.

Further, the guide 7 pivotally supports a guide roller 10 on the inner surface of the end portions of both side walls of the frame body 9 which is formed in a U-shape in cross section, and also pivotally supports a guide roller 11 at the innermost central part of the frame body 9. are doing.

Then, both edges of the forward path portion of the conveyor belt 8 inserted into the frame body 9 are brought into rotational engagement with the guide rollers 10 from the inner back side of the frame body 9, and the center of the backward path portion of the conveyor belt 8 is brought into contact with the guide rollers 10 from the inner back side of the frame body 9. The guide roller 11 is engaged with the frame body 9 from the inner back side.

In the embodiment, engaging protrusions 10' and 11' are formed on the outer peripheral surface of each guide roller i0.11, and the protrusions 1
The engagement holes 8' that engage with the holes 0' and 11' are shown in FIG.
As shown in FIG. The conveyor belt 8 on the outward path is moved by the roller 11 to the guide roller 1.
It is also possible to press and hold the conveyor belt at 0 (the ears of the conveyor belt are held between both guide rollers).

On the other hand, the center portion of the conveyor belt 8 is held between a pair of guide rollers 10 that are pivotally supported on the inner surfaces of the tip ends of both side walls of the frame body 9.
By forming the space 12 exposed to the outside,
A passage for a hanging member 13 coupled to the center of the conveyor belt 8 is formed.

In the embodiment, the tip of the hanging member 13 is connected to the moving end of the inner sheet material 4.5, but when configuring a normal conveying device, the conveying belt is connected via the hanging member 13. 8
All you have to do is suspend the load.

Further, the guide roller 11 for the return trip may be a drum-shaped roller that is stretched over the side wall surface of the frame 9.

In the above configuration, when any one of the guide rollers is rolled in either the forward or reverse direction, the conveyor belt 8 that is rollingly engaged with this guide roller is driven to run.

Therefore, the load suspended and supported by the conveyor belt 8 via the hanging member 13 moves together with the conveyor belt 8.

At this time, the conveyor belt 8 on the outward path that supports the load has both side edges in rolling engagement with the pair of guide rollers 10, so an unbalanced load is applied to the conveyor belt 8 via the hanging member 13. The conveyor belt 8 is always stably supported by the guide rollers 10 even when the conveyor belt 8 is moved.

Further, since a space 12 for passing the hanging member 13 is formed between the guide rollers 10, the hanging member 13 passes through the guide 7 smoothly.

In the case of the embodiment, as the conveyor belt 8 travels, the inner layer sheet materials 4 and 5 are slid open and closed using the subframes 2 and 3 as guides.

As explained above, according to the suspended conveyance device according to the present invention, the conveyor belt for suspending and supporting the load is inserted into the frame body, and the guide whose both side edges are pivotally supported on the inner surface of the end portion of the side wall of the frame body Since the rollers are rollingly engaged, there is no risk that the conveyor belt will come off the guide rollers even if an unbalanced load is suspended on the conveyor belt via the hanging member, resulting in stable suspended conveyance operation. can be made to do so.
