Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor with a sorting device.

[0002]

2. Description of the Related Art As a belt conveyor with a sorting device, for example, there is a belt conveyor as shown in FIG.
As shown in the drawing, a belt conveyor in which a conveyor belt 91 is stretched between a pair of rollers 90, 90, and an object H transferred by the conveyor belt 91 progresses in the middle of the transfer. A sorting device 92 for moving the conveyance object H in the horizontal direction, and a chute 93 (or other conveyor) provided in a portion for moving the conveyed object H in the horizontal direction.
It is composed of

In the case of using a belt conveyor with a sorting device, for example, the type of the transported object H is identified by a sensor and the sorting device 92 is driven, so that various types of transported objects H can be transferred to the same type of transported object H. It is very convenient because it can be sorted every time.

However, the sorting of the transferred object H by the sorting device 92 is performed in such a manner that the transferred object H is slid on the transfer belt 91 having a relatively high friction coefficient. The transfer belt 91 is pushed in the moving direction of the transferred object H, which causes the transfer belt 91 to meander. Therefore, when the belt conveyor is operated at a certain speed, the transported object H
May fall on the transport belt 91, or in the worst case, the transported object H may fall off the transport belt 91, which is not preferable.

[0005]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a belt conveyor with a sorting device in which the conveying belt does not meander when the object to be conveyed is moved in a direction transverse to the traveling direction of the conveying belt by the sorting device. The task is to provide

[0006]

A belt conveyor with a sorting device according to the present invention is of a type in which a conveyed object H conveyed by a linear belt conveyor 1 is laterally moved by a sorting device 2 for sorting. In the belt conveyor with a sorting device, an end portion of the transport belt 10 on the opposite side to the side on which the transported object H is moved in the lateral direction is supported by the holder 3. In addition, regarding the above-mentioned conveyor,
A bead portion 11 is provided at an edge of the conveyor belt 10,
On the other hand, the holder 3 has a pair of rotating bodies 30, 30, and at least one rotating body 30 is
1 so as to abut on the edge portion of the transport belt 10.

When this conveyor is used, and the conveyed object H transferred on the conveyer belt 10 is moved laterally by the sorting device 2, the frictional force between the conveyed object H and the conveyer belt 10 is increased. Causes a lateral moving force to act on the transport belt 10. In this case, the holder 3 supports the edge portion of the transport belt 10 on the side opposite to the side on which the transported object H is moved in the lateral direction. Therefore, the transport belt 10 does not meander. Therefore, even when the belt conveyor is operated at a certain speed, it is possible to avoid a situation in which the transported object H falls on the transport belt 10 or the transported object H drops from the transport belt 10. You can do it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings.

FIG. 1 shows a belt conveyor with a sorting device according to an embodiment of the present invention.

As shown in FIG. 1, this belt conveyor with a sorting device is basically a linear type belt conveyor.
A sorting device 2 provided beside the belt conveyor 1, a holder 3 provided near the sorting device 2,
A chute 4 (another conveyor may be provided) provided to face the holder 3 with the belt conveyor 1 interposed therebetween.

As shown in FIG. 1, the belt conveyor 1 basically has a conveyor belt 10 stretched between a pair of rollers 12, 12, and an inner peripheral surface of the conveyor belt 10. As shown in FIG. 2, a mountain-shaped bead portion 11 is fixed to the side edge. In addition, although not shown, a sensor for identifying various types of conveyed objects H for each type is disposed behind the above-described sorting device 2 in the belt traveling direction.

As shown in FIG. 1, the sorting device 2 includes a vertical axis 20 and a swing lever 21 attached to an upper end thereof.
The swing lever 21 is configured to swing from a solid line position to a two-dot chain line position in FIG. 3 according to an output signal generated from the sensor when the sensor identifies a predetermined transported object H. .

The sorting device 2 is a swing type of the swing lever 21, but is not limited to this, and may be a push type using a cylinder.

As shown in FIGS. 1 and 2, the holder 3 includes a rotating body 30 that contacts the upper surface of the block 31 and the conveyor belt 10, and a rotating body 30 that contacts the inclined surface of the bead portion 11.
The two rotating bodies 30, 30 sandwich the edge of the transport belt 10.
The rotating body 30 can be constituted by a bearing, and the inner race of the bearing is supported by the block 31 and the outer race of the bearing is used as a contact surface with the conveyor belt 10 and the bead portion 11.

As shown in FIGS. 1 and 2, the chute 4
The steel plate is formed by bending the steel plate into a U-shaped cross section, and the upper end thereof is provided near the upper surface of the transport belt 10 so as to coincide with the upper surface of the forward path.

Since the belt with the sorting device is configured as described above, the conveyor belt 10 does not meander, as described in the section of the means for solving the problems. Even when the conveyor belt is driven at a high speed, the object
It is possible to avoid a situation in which the object H falls down or the object H falls from the conveyor belt 10.

FIG. 3 shows a holder 3 and a conveyor belt 10 according to another embodiment. This embodiment is used for sorting an object to be transported H in the left and right direction of the conveyor belt 10.

FIG. 4 shows a holder 3 and a conveyor belt 10 of still another embodiment. The feature of this embodiment is that a bead portion 11 surrounds the edge of the conveyor belt 10 on both sides, and the rotating bodies 30, 30 are attached to the block 31 in a horizontal C-shape.
