Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-speed sorter for sorting loads conveyed by a belt conveyor, and more particularly, to a conveyer conveyor unit forming one end of one endless belt. The present invention relates to a high-speed sorting machine including a movable belt portion forming the other end portion and a sorting mechanism portion for rotating the movable belt portion leftward and rightward with respect to a conveyor according to a transported object.

Conventional technology Conventionally, as a sorter of this type, a pan type, an embossing type,
Various types such as an extrusion type and an oblique belt type are known.

However, in such a sorting machine, a sorting machine capable of sorting irregularly shaped packages and having an extremely small impact on the packages at the time of sorting has not been put into practical use. That is, each sorter has advantages and disadvantages, and none of them has all the advantages of each sorter. For example, in a sorting machine that includes a movable belt portion that is hung on a movable frame that is rotatably provided to the left and right at the end of a conveyer portion that moves a conveyed object straightly, which is hung on a fixed frame. Is
It is necessary to provide a space for rotating the belt portion of the movable frame between the two belt portions, and it is difficult to avoid the bite of the conveyed product into this space and the impact of the conveyed space on the conveyed product.

Further, for example, as a skewed belt type, as a belt type branching and merging device for branching a load from a fixed conveyor to a branching conveyor, a main support frame operated by a cylinder rod through two rods of long and short lengths and two arms. A Japanese Patent Publication No. 63-3810 discloses a movable device for sorting operation, which includes an auxiliary supporting frame and a belt-type branching and merging device. Also, since the belt is stretched around the two end pipes around the drive pulley supported by the main support frame and the end pulley supported by the auxiliary support frame, there is little impact on the transported object, but the transport conveyor section Another belt is used to support the drive device for driving the same on the support frame, and not only a large amount of power is required for the rapid movement of the heavy support frame. In addition, there is a drawback that a large space and equipment are required because it is necessary to install them in series when sorting right and left. Further, it is also known that a chain conveyor provided with a unit plate is used, and a play portion is provided on this chain so that the end chain vehicle can be moved left and right, but the surface is not smooth and large rotation is not possible. Difficult,
It was not applicable to all packages.

Therefore, the present invention has been made in order to solve the above-mentioned drawbacks of the conventional sorting machine, and makes it possible to easily rotate the movable part of the conveyor belt which conveys the conveyed object on the same plane with respect to the conveying conveyor part. It is an object of the present invention to provide a high-speed sorting machine that can be easily and quickly constructed.

Means for Solving the Problems In order to achieve the above object, the present invention comprises a conveyor section forming one end of an endless belt, and a movable belt section forming the other end of the endless belt. In a high-speed sorting machine consisting of a sorting mechanism section for rotating the movable belt part to the left and right with respect to the transport conveyor according to the transported object,
A belt bent portion is formed between the transport conveyor portion and the movable belt portion, and a movable member that supports the belt bent portion and a movable belt support member that supports the movable belt portion are rotatable about a rotating shaft. And is rotated by a predetermined amount by the drive source of the sorting mechanism section, and sorts the conveyed objects conveyed by the conveyor section into either straight traveling or right and left.

Action A belt bent portion is formed between the transport conveyor portion and the movable belt portion, and a movable member that supports the belt bent portion and a movable belt support member that supports the movable belt portion,
The movable belt portion is rotatably supported by the rotary shaft and is rotated by a predetermined amount by the drive source of the sorting mechanism section to sort the conveyed objects conveyed by the conveying conveyor section either straight or left and right. Since the rotation can be performed between the transport conveyor section and the belt bending section and between the belt bending section and the movable belt section, respectively, it is possible to reduce skew of the belt during belt bending,
The belt travels smoothly during rotation, and the movable member that supports the bent portion of the belt and the movable belt support member that supports the movable belt portion can be rotated easily and quickly, so that the conveyed object can go straight.
