Abstract

PURPOSE:To securely fix a material to be carried on a load carrying platform, and to prevent the generation of positional deviation during carrying. CONSTITUTION:Side movement of a material 24 to be carried, which is pinched by a presser plate 15 and a load carrying platform B, is restricted by a high friction layer 19 formed in the lower surface of the presser plate 15. Consequently, since the material 24 to be carried can be securely fixed onto the load carrying platform B, even in the case where a travelling truck A suddenly starts, stops or turns, slip of the material 24 to be carried on the load carrying platform B and a fall thereof from the load carrying platform B can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspending and conveying device (hereinafter referred to as a suspending and conveying device) for sandwiching and conveying a load between a loading platform suspended from a traveling carriage and a holding plate provided directly below the traveling carriage. , And is simply referred to as a carrying device.), And more particularly, to an improvement of a holding plate for holding a load provided in the carrying device.

[0002]

2. Description of the Related Art In factories and the like, when a conveyed object such as a container containing a large number of parts conveyed by a conveyor is supplied to a processing step or stored in a warehouse, this kind of object is used. A carrier is used.

In this carrying apparatus, a holding plate is provided directly below the traveling carriage in order to securely hold and fix the object to be conveyed between the traveling carriage and the loading platform.

An example of this type of holding plate is disclosed in the specification and drawings attached to the application of Japanese Patent Application No. 5-143357 filed by the applicant. This pressing plate is mounted so as to be slidable along a suspension rod provided on the lower surface of the traveling carriage, and is constantly urged downward by a compression spring.

[0005]

However, since the conventional pressing plate is made of a material such as a rigid steel plate having a hard surface, the material to be conveyed is a relatively slippery material such as a plastic container. In the case of the above, even if the loading platform pushes up the transported object from below, the transported object is in a slippery state.

For this reason, when the object to be conveyed reaches a curve or a branch point and the speed suddenly drops, or when the object or the object passes the curve or branch point and the speed suddenly rises, the object to be conveyed is placed on the platform. May slip and cause a positional shift. Therefore, due to this misalignment, it is not possible to correctly carry the load from the transfer device to the conveyor,
There is a problem that the object to be conveyed collides with the pillar of the conveyor during the transfer of the object to be conveyed and the conveying device stops. In such a case, the recovery of the transport device requires a great deal of manpower and time, and is very unsatisfactory.

Further, in order to prevent the displacement of the conveyed object, a guide shelf and an engaging plate have been conventionally provided to deal with the problem.
In the unlikely event that the engagement plate opens during traveling of the luggage platform,
There is a possibility that the transported object may fall from the loading platform.

The present invention has been made to solve the above-mentioned problems of the prior art, and it is possible to securely fix an object to be transported without moving on the bed during the movement, and to prevent the displacement thereof. Therefore, the object is to carry the object to be carried without any trouble.

[0009]

In order to achieve the above-mentioned object, the present invention suspends and supports a traveling carriage that travels along a rail installed on a ceiling or the like by a motor, and In a suspending and conveying device in which a pressing plate for pressing a load is provided immediately below and the object to be conveyed is sandwiched between the pressing plate and the loading platform to prevent displacement of the load on the lower surface of the pressing plate. A high friction layer is provided to solve the above problems.

Further, in the present invention, instead of providing the high friction layer as described above or in combination with the high friction layer, bent pieces facing downward may be formed at both ends of the holding plate. The high friction layer is preferably formed of an elastic body.

[0011]

The high-friction layer formed on the lower surface of the holding plate suppresses lateral movement of the conveyed object held by the holding plate and the loading platform. Therefore, since the transported object can be reliably fixed on the loading platform, it is possible to prevent the transported object from sliding on the loading platform or dropping from the loading platform even when the traveling vehicle suddenly starts, suddenly stops, or turns rapidly.

[0012]
