With this constitution, the truck 1 is conveyed (B) on the specified route 5.

Description

[Detailed Description of the Invention] The industrial field of application is Mikkomei, which is used to transport non-driven movable objects along a fixed path, such as carts that can move freely or trolley devices that can move freely on the ceiling. This invention relates to a movable body transport device.

2. Description of the Related Art In the past, when a non-driven trolley was transported along a fixed route, a hanging piece was hung from the bottom of the trolley, as seen in, for example, Japanese Utility Model Publication No. 59-2865. A configuration has been proposed in which a chino is disposed at a plurality of locations on the chino, and button protrusions that can be freely engaged with the hook pieces are provided at a plurality of locations on the chino.

Problems to be Solved by the Invention According to the above-mentioned conventional method, the chenos must be arranged over the entire length of a certain path, which makes the entire length of this fixed path complicated, and the trolley has no hooks. The pieces must be installed accurately.

The purpose of the present invention is to eliminate the complexity of most of the remaining parts by only having to install it on a part of a fixed route, and furthermore, it is not necessary to provide a passive member on the movable body for transporting the movable body. The point is to provide equipment.

Means for Solving the Problems In order to achieve the above object, the movable body conveying device of the present invention has the following features:
Vertical shafts linked to the rotating part #J device are provided on both sides of a fixed path along which the movable body can run freely, and oscillating bodies are fitted onto these vertical axes, and a oscillator is fitted on the M end of both oscillating bodies and on the side of the movable body. A suppressing roller that can freely come into contact is rotatably mounted, and a transmission device is provided between the suppressing roller and the vertical shaft to provide a drive device for swinging both rocking bodies.

Effects According to the configuration of the present invention, the movable body is positioned facing the movable body conveying device on a fixed path. And double rotary drive!
The IJ g position rotates the respective longitudinal axes, and these rotations are transmitted to both suppression rollers via a transmission, forcing both suppression rollers to rotate in mutually opposite directions. When the swinging body is swung inwardly by the swinging drive device in this state, the suppression rollers that have moved inward through both oscillating bodies are pressed against both side surfaces of the movable body. At this time, both the push rollers are eccentric with respect to the vertical axis, so the biting force is n1, and since they are forced to rotate in opposite directions, they apply a large running force to the movable body. The movable body is transported on a fixed path. In this case, the movable body backs up the movable body group that is stopped in front of it and conveys it.

Effect of light According to the present invention having the above configuration, the dual rotary drive #J device provides
By rotating their respective vertical axes and transmitting these rotations to both suppression rollers via the transmission VJ device, it is possible to forcibly rotate both suppression rollers in mutually opposite directions. Therefore, with the movable body positioned facing the movable body conveyance device on a fixed path, both the rocking bodies are swung inward by the swing drive vJ device, and the pressing rollers are pressed against both sides of the movable body. By doing so, it is possible to apply running force to the movable body by both pressing rollers rotating once in opposite directions, and since the pressing rollers are eccentric with respect to the vertical axis, no jamming force is generated. , a small push can produce a large thrust, which allows the movable body to be reliably transported along a fixed path. At this time, the movable body can push and transport the movable body group that is preceding and stopping. As a result, the movable body conveyance device only needs to be installed on a part of a certain route, and most of the remaining parts can be uncomplicated.Furthermore, there is no need to provide a passive member on the movable body, which simplifies the process.
