Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a conveyor for conveying a long object, and in particular, the invention relates to a conveyor for conveying a long object, and in particular, the invention relates to a conveyor for conveying a long object. It relates to a transport conveyor.

(Prior Art) Generally, a conveyor for conveying a workpiece is specially designed to match the shape of the workpiece (Japanese Patent Laid-Open No. 127631/1983).

Furthermore, as a conveyor for conveying a long object horizontally perpendicular to the conveyance direction, conveyors such as those shown in FIGS. 4a, b and 5a, b have been mainly used. was.

Among these, the one shown in FIGS. 4a and 4b is for conveying an irregularly shaped long object (for example, a bumper of a car) 1 having a protrusion 1a on the lower surface. 2 and 3 (in addition,
(The other drum paired with these drums is not shown), endless belts 4 and 5 are attached to each drum 2 and 3.
The endless belts 4 and 5 are driven by the synchronous rotation of the drums 2 and 3.

In such a conveyor, by appropriately adjusting the pitch of the two drums 2 and 3, it is possible to convey the irregularly shaped long object 1 in a manner that avoids the protrusion 1a, and it is possible to convey the object 1 having the protrusion 1a that is easily deformed. You will be able to respond adequately to things.

On the other hand, the one shown in FIGS. 5a and 5b is for conveying a plate 6, and is equipped with a long drum 7 and a wide endless belt 8 wound around it. In such a conveyor, almost the entire lower surface of the plate 6 can be received by the endless belt 8, making stable conveyance possible. In addition,
As a special example of a wide conveyor, the drums 2 and 3 shown in FIG.
There is also a belt equipped with a wide endless belt 8 as shown in Figures 5a and 5b (Japanese Patent Laid-Open No. 55-40472
Publication No.).

(Problem to be solved by the invention) Incidentally, at production sites, production items often change, but according to the above-mentioned conventional conveyor, the type of object to be conveyed, that is, the irregularly shaped long object 1 Therefore, each time the production item changes, it is necessary to rearrange the different types of transport conveyors, which requires a lot of time and labor, and is not economical. The problem was that it was a heavy burden.

The present invention was devised in view of the above problems, and its purpose is to provide a conveyor that can transport objects of different shapes, such as irregularly shaped long objects and plate objects, without having to be rearranged. It is about providing.

(Means for Solving the Problems) As a means for solving the above problems and achieving the purpose, the shaft members for supporting the drum are divided and provided so that they can approach and separate from each other in the axial direction, and Large-diameter drums are attached to both ends of the shaft member, and a plurality of small-diameter drums are fitted to the shaft member so as to be slidable in the axial direction, and one of the small-diameter drums is formed to be longer than the others. The distal end portions of the two divided shaft members are arranged at a position where they are connected, and a belt-like belt is stretched around each drum.

(Function) In the transport conveyor having the above configuration, the belt-shaped belt stretched around the large-diameter drum supports and transports irregularly shaped long objects that have protrusions that are easily deformed while avoiding the protrusions. can do. Furthermore, even if the positions of the protrusions of irregularly shaped and long objects differ, by separating the shaft members and adjusting the interval between the large diameter drums, it is possible to avoid the protrusions and support and convey the optimal position. can.

In addition, plate objects can be conveyed using a belt-shaped belt stretched over a small-diameter drum.Furthermore, by separating the shaft members in the axial direction to widen the overall width, and moving the small-diameter drum in the axial direction, wide plates can be conveyed. Even objects can be transported using small-diameter conveyor belts. In this way, the range of application of objects to be transported can be expanded.

(Example) Next, an example of the present invention will be described based on FIGS. 1 to 3.

In the conveyor 9 of this embodiment, as shown in FIG.
0 and 11 are arranged. A driving means (not shown) is connected to one of the belt winding parts 10 and 11.

As shown in FIGS. 1 and 2, the belt winding parts 10 and 11 have a shaft member 12 divided into left and right halves at the center, and left and right shaft members 12a and 12b.
The respective divided ends of the shaft members 12 are slidably fitted to the inner periphery of the central drum 14 on which the band belt 13 is stretched.
move a and 12b in the axial direction and approach in the axial direction,
They can be separated freely. And this shaft member 12
The movement of a and 12b may be performed manually or mechanically using a cylinder device or the like.

A large-diameter drum 15 is attached to the outer end of each shaft member 12a, 12b, and a belt-like belt 15 is attached to the outer end of each shaft member 12a, 12b so as to be able to support an irregularly shaped long object 1 that is easily deformed.
6 is hung. In addition, each shaft member 12a, 1
2b, a plurality of drums 17 having the same diameter and shorter length as the central drum 14 are slidably fitted, and a belt-like belt 18 is stretched around each of the drums 17 so as to be able to transport the plate 6. It is suspended.

Note that 19 shown in FIG. 2 is the shaft member 12a, 1
This is an annular stopper for fixing each small diameter drum 17 at a desired position when the drums 2b are separated to widen the conveyance width.

With this configuration, when conveying the irregularly shaped elongated object 1, the irregularly shaped elongated object 1 is placed on the belt-like belt 16 while avoiding the protrusion 1a, as shown in FIG. This prevents the protrusion 1a from interfering with the belt-shaped belt 18 stretched over the small-diameter drum 17, allowing stable conveyance of the irregularly shaped long object 1.
In addition, when conveying the irregularly shaped long object 1 with different positions of the protruding parts 1a, by separating the shaft members 12a and 12b and adjusting the interval between the large-diameter drums 15, the irregularly shaped long object 1 to be conveyed can be adjusted. The optimal support position can be selected depending on the position of the protrusion.

On the other hand, when conveying the plate 6 as the object to be conveyed, the small diameter drum 17 inside the large diameter drum 15
It may be placed on the upper surface of the belt-like belt 18 stretched over the belt. In addition, when conveying a wide plate 6, as shown in FIG.
After separating the small-diameter drums 17 so that they are at approximately equal positions, they are fixed with stoppers 19 to widen the total width of the conveying surface. In this way, the entire surface of the plate 6 is brought into contact with the belt-shaped belt 18 stretched over the small-diameter drum 17, and stable conveyance can be achieved.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and can be applied to a large diameter drum 15 and a small diameter drum 1.
The number, shape, and arrangement position of 7 can be changed as desired.

(Effects of the invention) As explained in detail above, the invention provides a large-diameter drum and a small-diameter drum, and also allows each drum to be moved in the axial direction of the shaft member to change the pitch. By selectively using a strip belt stretched over a small-diameter drum and a strip belt stretched over a small-diameter drum, it is possible to transport multiple types of objects with different shapes and lengths using a single conveyor. As a result, the cost of production equipment can be significantly reduced, and productivity can also be improved. Furthermore, when a plate object is conveyed using a small-diameter drum, the large-diameter drums on both sides prevent the plate object from falling off, thereby stabilizing the conveyance.
