DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveying device such as a slat conveyor, a slat-type sorting device, and a wire mesh belt conveyor, in which a material supporting surface circulates endlessly.
In particular, the present invention relates to a structure for preventing a small conveyed article or the like from falling from a conveying side to a return side.

[0002]

2. Description of the Related Art In a slat conveyor in which a plurality of slats are attached to an endless chain, or in a slat-type sorting device in which a shoe for pushing a conveyed product is incorporated between the slats of the slat conveyor, a gap is formed in a conveyed product supporting surface. Due to the formation, a small conveyed product may fall from the gap. Further, in the slat type sorting device, the shoe may be damaged, and its components may fall from the transport side to the return side. Slats and endless chains where such falling objects are located on the return side,
If it is caught or caught in a frame or the like, it may cause various troubles such as chain breakage and operation stop.

In addition, when this type of device is installed above a worker's head, compared to when it is installed on the floor,
There was a problem that the noise caused by the driving was felt loudly and hindered the work.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide means for preventing a falling object from a transport side from falling to a return side in a transport apparatus such as a slat type sorting apparatus. I have.

Another object of the present invention is to reduce the noise of the transfer device and improve the working environment of the worker.

[0006]

In order to achieve the above object, the present invention provides a pair of side frames, a pair of endless chains disposed between the side frames, and a fixed distance from each other. In a transport device composed of a plurality of slats attached between endless chains in a state in which the slats are mounted and a shoe supported on each slat so as to be able to move in the left-right direction, a so-called slat-type sorting device, There, almost in the middle between the transport side and the return side, over almost the entire transport range,
It is characterized by installing a partition plate containing soundproofing material.

[0007]

In the above-mentioned fallen object prevention structure, since the partition plate exists between the transport side and the return side, even if the transported article or the like falls from the transport side, it does not reach the return side. .

Further, since this partition plate includes a soundproofing material, it is possible to block the propagation of sound from the transport side to the return side or from the return side to the transport side.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings.

FIGS. 1 and 2 show a slat type sorting apparatus to which the present invention is applied. The slat-type sorting device includes a pair of endless chains 1a, 1b and endless chains 1a, 1b at a certain distance from each other.
A plurality of slats 2 mounted in between, each slat 2
The shoe 3 is supported so as to be movable in the left and right lateral directions (in the direction perpendicular to the transport direction).

Each of the endless chains 1a and 1b is wound around a pair of sprockets (not shown) provided at both left and right sides of the frame 4 of the sorting apparatus.
A drive source is connected to one of the sprockets, and the drive source drives the endless chains 1a and 1b to circulate through the sprockets. Circulated on the return side.

Each shoe 3 has a driven pin 6 extending from the gap 5 between the slats 2 to the back side of the slat 2. The driven pin 6 is slidably fitted in a guide groove 8 of a rail 7 provided along the back surface of the slat 2. The conveying side, that is, the upper rail 7 is branched at the sorting position, and the rail 7 through which the driven pin 6 of the shoe 3 passes.
Is switched from the straight rail 7a to the branch rail 7b, so that the shoe 3 can be moved in the lateral direction as the slat 2 advances. In addition, the switching device 9 for switching the rail 7 through which the driven pin 6 passes is installed on a cross bar 11 that is laid across the side frames 10a and 10b.

The above-described structure is conventionally known, and the frame 4 has a skeleton structure in which steel materials such as angle steel and H-shaped steel are joined by rivets and bolts or the like. Therefore, as described above, when a small conveyed object falls from the gap 5 between the slats 2 on the conveying side, or when the driven pin 6 of the shoe 3 is broken, they are located on the slat 2 or the slat 2 located on the return side. It reaches the entry chains 1a and 1b.

Therefore, in the present invention, a veneer plate, a synthetic resin plate, or the like is provided between the left and right side frames 10a and 10b, substantially in the middle between the transport side and the return side, and over substantially the entire transport range. The partition plate 12 is provided. As in the illustrated embodiment, in the case of a normal sorting device or a transport device, the side frame 10
Since the crossbars 11 are laid horizontally at appropriate intervals between a and 10b, the partition plate 12 need only be placed on these crossbars 11 and need not be fixed with fastening means such as bolts and nuts. Absent. When the switching device 9 and other obstacles are present on the crossbar 11, the partition plate 12 is used to avoid interference between the obstacle and the partition plate 12.
It is effective to provide the notch 13 as appropriate at the corresponding position.

As described above, since the separation side between the transfer side and the return side of the sorting device is separated by the partition plate 12, even if a small conveyed object falls from the transfer side, the conveyed object is separated by the partition plate 12. It is accepted and does not reach the return side. Therefore, troubles such as biting of a conveyed object between the return slats 2 are prevented beforehand.

The partition plate 12 also functions as a sound insulation plate that blocks noise from the transport side to the return side or noise from the return side to the transport side. Therefore, especially when this sorting device is installed above the worker, the noise from the transfer side that emits a sound that is louder than the return side is cut off, so that the work environment of the worker is greatly improved. . From such a viewpoint, it is preferable that the partition plate 12 is formed from a plate material including a soundproofing material.

Further, when the sorting device is installed above the worker, if the partition plate 12 is made transparent, the existence of a falling object can be detected at an early stage.

The present invention is particularly effective for a slat-type sorting apparatus in which a falling object is easily generated and generates a large amount of noise. The above-mentioned embodiment also relates to a slat-type sorting apparatus. The present invention can also be applied to other transporting devices such as a wire mesh chain conveyor and a slat conveyor, which have a gap on a transported object support surface. Further, even in a normal belt conveyor or the like in which no gap is formed on the transported object support surface, there is a possibility that components such as bolts on the transport side may fall, so that the present invention can be effectively applied.

[0019]

As described above, according to the present invention, the falling object from the transport side can be received by the partition plate, so that various troubles that occur when reaching the return side can be prevented beforehand. Can be.

Further, since the partition plate also functions as a sound insulating plate, it is possible to reduce the noise from the transfer device and to improve the working environment of the worker.
