Abstract

PROBLEM TO BE SOLVED: To surely convey any subject and to prevent cost from increasing. SOLUTION: An endless belt 44 is wound on pulleys 20, 36, and the pulley 36 is supported on a swing arm 2 which swings about the rotation axis of the pulley 26 placed in the intermediate position. The lower surface of the endless belt 44 is supported by a pulley 49. The swing arm 28 can be swung by moving a piston rod 42 vertically. Since no seams exist in a conveyor path, even sheet-shaped flexible materials to be conveyed, such as tire components, and earth and sand, etc., can surely be conveyed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing type belt conveyor capable of changing a conveying direction of a conveyed object.

[0002]

2. Description of the Related Art Conventionally, there has been a swing type belt conveyor capable of changing a conveying direction of a conveyed object as shown in FIGS.

The swing type conveyor 100 shown in FIG.
It comprises a first conveyor 102 and a second conveyor 104. The second conveyor 104 has one pulley 10
6 can be pivoted about the rotation center as indicated by an arrow A, and the carry-out direction of the conveyed article can be changed, for example, up and down.

The swing type conveyor 108 shown in FIG.
A first pulley 110, a second pulley 112, and a third pulley 114;
2, a plurality of narrow endless belts 116 are wound around at intervals, and a plurality of endless belts 118 are wound around the second pulley 112 and the third pulley 114.
It is wound around 16.

[0005] The first pulley 110 and the second pulley 112 are supported by an arm 120 and can swing about the second pulley 112 as a rotation center as indicated by an arrow A.

[0006]

However, the conventional swing type belt conveyor has the following problems.

A swing type belt conveyor 10 shown in FIG.
0, a connecting portion (gap) 122 is formed between the first conveyor 102 and the second conveyor 104, so that when a member without a flexible body such as a rubber sheet is conveyed, the connecting portion 122 In some cases, jamming or the like may occur due to difficulty in moving through, and is not suitable for conveying a member having no stiffness. In the case of transporting soil and the like, the soil and the like spill out from the joint portion (gap) 122.

On the other hand, in the swing type belt conveyor 108 shown in FIG. 7, since there is a gap between the belts, for example, when a flexible member without a stiffness, such as a rubber sheet, is conveyed, A sliding plate, a roller, or the like that fills the gap is required, which increases the number of parts and increases the cost. Also, since there are many gaps, it is not suitable for transporting earth and sand.

The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a swing type belt conveyor that can reliably convey any kind of conveyed material and does not increase the cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a swing type belt conveyor according to the present invention will be described with reference to FIGS.

As shown in FIG. 1, the swing type belt conveyor 10 of this embodiment includes a pair of columns 12 erected on a floor surface (not shown). Is fixed to the side surface extending in the direction of arrow R.

A bearing 16 is mounted on the upper surface of each horizontal column 14, and a shaft 18 is rotatably supported by these bearings 16. A pulley 20 as a second pulley is fixed to an intermediate portion of the shaft 18.

A bearing 22 is attached to each of the columns 12 on the side in the direction of the arrow L, and a shaft 24 is rotatably supported by these bearings 22. A pulley 26 as a third pulley having the same diameter as the pulley 20 is fixed to an intermediate portion of the shaft 24.

One end of a swing arm 28 is supported on the shaft 26 via a bearing 30 between the bearing 22 and the pulley 26.

A bearing 32 is attached to the other end of each swing arm 28, and a shaft 34 is rotatably supported by these bearings 32. A pulley 36 as a first pulley having the same diameter as the pulley 20 is fixed to an intermediate portion of the shaft 34.

The two swing arms 28 are connected to the connecting member 3.
8 are connected to each other. A piston rod 42 of a hydraulic (or air) cylinder 40 is connected to the connecting member 38 via a joint 43. When the piston rod 42 is moved up and down, the swing arm 28 swings about the shaft 24.

An endless belt 44 is wound around the pulley 20, the pulley 26, and the pulley 36.

A shaft 47 is rotatably supported by the horizontal column 14 near the column 12 via a bearing 45. A pulley 49 as a fourth pulley is fixed to an intermediate portion of the shaft 47. The pulley 49 supports a transport surface (outer surface) of the endless belt 44 on a side facing a floor surface (not shown).

A sprocket 46 is attached to one end of the shaft 34. The sprocket 46 is connected to a sprocket 50 rotated by a belt driving motor 48 attached to the swing arm 28 by a chain 52.

A tire building drum 54 is arranged in the direction of arrow L of the swing type belt conveyor 10.

Next, the operation of the present embodiment will be described. When the belt driving motor 48 rotates, the rotation driving force is transmitted in the order of the sprocket 50, the chain 52, and the sprocket 46, and the endless belt 44 rotates by rotating the pulley 36.

Thus, the belt-shaped tire component (eg, ply, tread rubber, rubber chafer, etc.) 56 conveyed from a supply source (not shown) in the direction of arrow R can be conveyed to the tire building drum side.

Here, in order to retract the swing type belt conveyor 10 from the tire building drum 54 due to the work on the tire building drum 54 and the like, the piston rod 4
By raising 2, the side of the swing arm 28 in the direction of the arrow L can be retracted from the tire building drum in the horizontal direction, for example, as shown by the imaginary line in FIG.

The swing arm 28 is connected to the pulley 26
Swinging around the rotation axis of the swing arm 2
8, the belt conveyance path length is always constant. Even if the swing arm 28 is swung, the endless belt 44 is supported by the pulley 49 and does not slack.

Swing type belt conveyor 1 of the present embodiment
In the case of 0, since there is no joint in the transport path, even a sheet-like flexible transport object such as a tire component can be transported reliably.

In this embodiment, the tire component 5
Although the example in which the conveyor belt 6 is conveyed is shown, as shown in FIG. 3, one of the swing type belt conveyors 10 may be swung to separate the soil 62 and the like into a container 58 and a container 60 disposed below. Can be. This swing type belt conveyor 1
In the case of No. 0, since the conveyance is performed by one endless belt 44 from carry-in to carry-out, a conveyed object such as earth and sand 62 can be conveyed, and the conveyed object is not dropped on the way.

Further, as shown in FIG. 4, three stock conveyors 64, 66, and 68 are vertically arranged between a pair of swing type belt conveyors 10 and sent from one of the swing type belt conveyors 10. The conveyed material (for example, rubber sheet, paper, film, etc.) is transferred to
4, 66, 68, and can be temporarily stocked.

In the above embodiment, the swing arm 2
Although 8 was provided only on one side, as shown in FIG.
A swing arm 28 may be provided on both sides to swing on both sides. In the swing type belt conveyor 70 shown in FIG.
One pulley 36 is the first pulley of the present invention, the other pulley 36 is the second pulley of the present invention, and one pulley 2
6 is the third pulley of the present invention, the other pulley 26 is the fourth pulley of the present invention, one arm 28 is the first arm of the present invention, the other arm 28 is the second arm, and one pulley 49 is the present invention. The fifth pulley and the other pulley 49 correspond to the sixth pulley of the present invention.

When both pulleys 26 are close to each other, only one pulley 49 may be provided.
