Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving body used for moving a non-driving type moving body on a fixed route, such as a trolley that can run on the floor side and a trolley device that can run on the ceiling side. The present invention relates to a carrier device.

[0002]

2. Description of the Related Art Conventionally, as this type of apparatus, for example, a package processing apparatus disclosed in Japanese Patent Publication No. 60-288 is provided. In this conventional configuration, a plurality of rigid bodies such as square pipes having both sides formed in parallel straight lines and having an appropriate length are connected in the front-rear direction to form an endless shape, and each rigid body has a carrier panel appropriately fixed to the upper surface. It is possible to run along the guides provided in the fixed part while overlapping with each other in the front and rear stages, and a fixed friction wheel is provided on one side fixed part on both sides of the straight traveling path of the rigid body, and on the other side fixed part. Moving friction wheels, which are always urged to be able to push toward the fixed friction wheel side with appropriate elastic force, are arranged so that they can be synchronously driven by the same drive source, and the rigid body group is driven by clamping pressure contact by both friction wheels. Are circulated.

[0003]

However, since the above-mentioned conventional structure is connected endlessly, it can be used only in the circulation path, and cannot be used in the straight path. If the rigid body group in a train shape is used as a line with endless shape, a tensile force acts on the rigid body group lower than the clamping pressure contact drive unit and the upper hand passing through the clamping pressure contact drive unit moves. The pushing force will be applied to the rigid body group of, and therefore, due to the rattling joint structure of the universal joint for connecting, noise is generated due to a collision when changing from pulling to pushing and the connecting portion It will cause damage.

Further, since the moving friction wheel is always urged by an appropriate elastic force so as to be able to be pushed toward the fixed friction wheel side, when the elastic force is weak, the clamping force is low and the moving force is surely given. When the elastic force is strong, the rigid body cannot be smoothly transferred between the friction wheels. Further, the division between the rigid bodies cannot be easily performed, and therefore, when the carrier panel is of a trolley type, it is not easy to separate the trolleys to run.

An object of the present invention is to allow a plurality of moving bodies to move in a dense train form, even though they are of a non-connection type.
Moreover, it is a point to provide a movable body transport facility which can sufficiently and surely and smoothly apply the moving force to the movable body.

[0006]

In order to achieve the above-mentioned object, a moving body transporting apparatus of the present invention is provided with a constant path in which a plurality of moving bodies can be moved in a line in a substantially contact state, The body is provided with a plate-shaped pressure receiving body vertically extending from the lower surface over the entire length in the longitudinal direction, and on the upper side of the fixed path, a moving force applying device for applying a moving force to the moving body is provided. ,
A pair of vertical axes rotatably supported on the gantry side, a rotary drive device linked to one vertical axis, a first oscillating body externally fitted to the upper part of one vertical axis, and fixed to the upper part of the other vertical axis. A second oscillating body, rotating shafts attached to the free ends of the oscillating bodies and extending along the vertical axis, and a pressing roller attached to these rotating shafts and capable of abutting from the left and right sides of the pressure receiving body. And both pressing lo
And a rocking drive device that rocks both rocking bodies toward and away from each other, and the left and right sides of the pressure receiving body on the lower side of the fixed path. There is provided a braking force applying device that acts on the moving body to apply a braking force to the moving body.

[0007]

According to the structure of the present invention, the moving body is thrown into the position facing the moving force imparting device on the fixed path. At this time, the oscillating drive device is operated to oscillate both oscillating bodies outward about the axial center of the vertical axis to separate the two pressing rollers from each other, and therefore, there is no problem in putting them in. You can do it.

Then, after the closing operation, the two pressure rollers are moved closer to each other by the reverse action of the swing drive device, so that the two pressure rollers are pressed against the side surface of the pressure receiving body with a sufficient pressure contact force (holding force). At the same time, by rotating and driving both pressing rollers, a sufficient moving force can be given to the moving body, and the moving body can be surely and smoothly moved on a fixed route. That is, one of the vertical axes is rotated by the rotary drive device, and the rotation of the vertical axis is transmitted to the pressing roller via the transmission device, and both pressing rollers can be forcedly rotated in opposite directions. Therefore, the pressing roller that is forcibly rotating is pressed against the side surface of the passive body to give a moving force to the moving body, which allows the moving body to move on a fixed path. At that time, the moving body moves by pushing the moving body group that is preceding and stopped.

When the moving body is pushed by the moving force applying device, the braking force applying device acts on both side surfaces of the passive body for the moving body located on the lower side of the fixed path. Therefore, it is possible to prevent a braking force from acting on the moving body and to prevent the vehicle from escaping. Furthermore, a gap does not occur between the moving body groups located between the moving body and the moving force applying device, and a collision noise does not occur. Can be pushed and moved. That is, the moving body group moves in a fixed path in a line in series in a substantially contact state. Then, the moving body separated from the braking force applying device is separated from the moving body group.
