Description

Transport device

The present invention relates to a conveying apparatus including a pair of spiral plate-shaped members for conveying a conveyance of a box-shaped container or the like in a vertical direction.

In the case of transporting a container such as a box-shaped container in the vertical direction, a conveyor-type conveying device using a conveyor belt such as a belt conveyor is widely used. In the conveyance device of the conveyance belt, the conveyance surface of the conveyance conveyance is provided at a constant angle with respect to the horizontal direction, and the conveyed object is moved in the horizontal direction and the vertical direction simultaneously in the oblique direction, that is, while the conveyed object is simultaneously moved in the horizontal direction and the vertical direction. Slowly transport in the up and down direction.

However, in the conveyor type conveyance device, if the inclination angle is too large, it is difficult to convey the conveyed object, and therefore it is necessary to reduce the inclination angle. On the other hand, when the inclination angle is reduced, the length of the conveyor belt required to convey the conveyed object in the vertical direction becomes long, and the horizontal dimension of the conveyance device remarkably increases.

In addition, since the conventional conveyor belt type conveyance device has a large number of components, it is relatively easy to cause an abnormality, and the maintenance frequency is increased, and the reliability cannot be improved. In the structure in which the conveyance is performed in the up-and-down direction, the structure is complicated, and the conveyance device is excessively heavy, and the manufacturing cost is required, which causes a problem of an increase in the amount of the conveyance device.

In addition, it is known that there is a snail different from the above-described conveyor type conveying device. In the case of the transfer device, the screw-type transport device is used to transport the transported objects such as the box-shaped container in the vertical direction (see Patent Document 1).

According to the first conventional spiral type conveying apparatus, as shown in FIG. 1 of Patent Document 1, a pair of column-shaped wing fixing portions are arranged in parallel with each other, and on the outer peripheral surfaces, a long plate having a width is formed in the length thereof. The wing portion formed in a spiral shape is wound in the direction, and the joint portion is integrally fixed by being welded to each other.

The first conventional spiral type conveying device has a pair of spirals that are interlocked with each other by a pair of wing fixing portions, and a guide surface that is substantially parallel to a surface including both axes of the pair of spirals. The guide member is constructed.

Further, in the first conventional spiral type conveying device, the conveyance is placed on the upper surface of the wing portion having the width from the respective wing fixing portions of the pair of spirals, and a part of the conveyed material and the guide are placed. In a state in which the guide faces of the lead members are in contact with each other, the pair of spirals are rotated in the opposite direction, whereby the transported articles can be moved in the vertical direction.

In the above-described first-type screw type conveying apparatus, compared with the above-described conventional belt type conveying apparatus, the outer size thereof can be reduced, the installation occupied area can be reduced, and the number of parts can be reduced. It can improve its reliability.

Therefore, the spiral having such a wing portion is heavy, and the spiral is provided. The problem of excessive weighting of the transport device.

Further, if the weight of the spiral becomes heavy, the driving portion or the rotating mechanism portion that rotates in the spiral is subjected to an excessive load. Therefore, there is a problem that the durability and reliability of the conveying device cannot be improved.

Further, the long plate having the width is formed into a spiral wing portion, or a spiral integrally formed by welding the wing portion around the outer peripheral surface of the wing fixing portion, which is expensive in material production and costs in manufacturing thereof Since a large amount of labor and expenses are incurred, the manufacturing price thereof is increased, and there is also a problem that the transportation apparatus having the spiral is expensive.

In order to solve the problem of the first conventional screw conveyor, a second conventional screw conveyor has been proposed (see Patent Document 2).

In the second-type spiral type conveying apparatus, as shown in FIG. 1 of Patent Document 2, a pair of cylindrical rotating columnar members are arranged in parallel with each other, and the outer shape of the cross section is substantially rounded around the circumference.

The second conventional screw type conveying device is a pair of spirals that are rotated in opposite directions by a pair of rotating columnar members, and has a substantially parallel plane with respect to an axis including both of the pair of spirals The guiding member of the guiding surface is formed.

Further, in the second conventional screw type conveying device, the conveyed object is placed on the upper semicircular arc surface of the conveyance support portion of each of the pair of spirals, and a part of the conveyed object and the guide member are placed. In a state in which the guide faces are in contact with each other, the pair of spirals are interlocked and rotated in opposite directions, whereby the conveyed object can be moved in the vertical direction.

In the second conventional screw type conveying apparatus, the weight of the screw can be reduced and the durability and reliability of the conveying apparatus can be improved as compared with the above-described first conventional screw type conveying apparatus.

However, the carrier support portion of the second conventional screw conveyor is formed by bending a round bar member having a substantially circular cross-sectional shape into a spiral shape. Therefore, it is required for the conveyance support portion. In the case of the length, it is necessary to join the end faces of the two spirally wound round bar members to each other by welding, and since the manufacture thereof is not simple and requires a large amount of labor and expense, the manufacturing price thereof rises, and This causes a problem of increasing the price of the conveying device including the conveying member support portion.

Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a conveying apparatus which can improve the durability and reliability of the conveying apparatus and which is easy to manufacture and can prevent the conveying apparatus from being excessively heavy or expensive.

In order to solve the above problems, a conveying apparatus according to the present invention includes: a pair of columnar members having a length in a vertical direction, and mutually arranged axes are arranged substantially in parallel; a pair of spiral plate members And the long-sized strip-shaped member is bent to form a spiral shape, and the spiral-shaped spiral winding direction is a pair of spiral curves in opposite directions along each other, and the pair of spiral plate members are as follows In a manner, the inner surface of the thickness direction is opposed to the columnar member at a distance from the columnar member around each of the pair of columnar members.
