Description

[Detailed Description of the Invention] [Industrial field of application] The present invention regulates a tilt with respect to a horizontal plane to a movable vehicle that can travel along a guide rail in an upper external portion of a processing chamber that is blocked from the outside by a partition wall. The present invention relates to a transportation facility in which an article supporter that supports an article is provided in a suspended state so as to pass through the processing chamber along an opening provided in the partition wall below a traveling route of the mobile vehicle.

[Conventional technology]

The transportation facility as described above is used in automobile production lines and the like, and the transportation route may include a cleaning or painting process. Then, such a cleaning or painting process is performed in the processing chamber which is shielded from the outside by the partition wall. That is, the atmosphere in the cleaning or painting process is often harmful or flammable, and a partition is provided to isolate the atmosphere. However, if the moving vehicle is made to travel in the processing chamber, various problems may occur, such as adversely affecting the moving vehicle and causing electric sparks when driving the moving vehicle electrically, The moving vehicle will be provided so as to travel above and outside the processing chamber.

By the way, in order to support the article by the article support tool, the article is supported with the longitudinal direction thereof oriented in the lateral direction of the moving vehicle. Supporting the article in this way is advantageous for reducing the length of the processing solution tank in the transport direction, for example, when the supporting article is immersed in the processing solution tank in the cleaning or painting process. This is because it is advantageous in terms of equipment configuration. By the way, in order to immerse the article in the treatment liquid tank, the guide rail is provided with a gradient so that the portion corresponding to the treatment liquid tank is at a lower position, and the article is allowed to enter and leave the treatment liquid tank as it is transported. Although it is generally configured as described above, it is also considered that the article supporter is provided so as to be able to move up and down with respect to the moving vehicle, and is dipped by moving up and down.

As described above, the article supporter that supports the article with its longitudinal direction oriented in the lateral direction of the moving vehicle is configured as follows, for example. That is, by providing four supporting rods arranged at intervals in the lateral direction of the moving vehicle in a front view and at intervals in the front-rear direction of the moving vehicle in a side view, the front left and right supports are provided. The article is supported between the working rod and the left and right supporting rods on the rear side with the longitudinal direction of the article oriented in the lateral direction of the moving vehicle.

In order to suspend and support this article support tool on a moving vehicle, conventionally, a pair of left and right rod-shaped vertical frames extending in the up-down direction when viewed from the front is provided at the same spacing as or at a spacing close to the support rods arranged side by side. The left and right rod-shaped vertical frames are provided to connect the moving vehicle and the article support.

However, in such a conventional structure, since the pair of left and right rod-shaped vertical frames are located at intervals in the lateral width direction of the moving vehicle, the groove-shaped opening formed in the partition wall has a wide narrow portion. There was a risk that a large amount of the atmosphere would leak out through the opening.

Of course, this opening can be covered with a pair of left and right covers made of rubber or the like, and the pair of left and right covers can be pushed open by the rod-shaped vertical frame, thereby suppressing the leakage of the atmosphere. Since the groove-shaped opening has a wide width, the cover installation cost becomes high and the overall cost becomes high.

Further, as disclosed in Japanese Patent Laid-Open No. 59-4591, a moving vehicle and an article support are connected through a vertical member made of a pair of front and rear rigid bodies along the traveling direction of the moving vehicle, and this vertical member portion is connected. There is also known a structure in which the vertical member is positioned at the groove-shaped opening of the partition wall, and the vertical member is moved up and down at the opening, and the article supporter connected below the vertical member is moved up and down.

[Problems to be solved by the device]

However, in the device disclosed in the above publication, since the moving vehicle and the article support are connected through the rigid vertical member, the vertical member having a relatively heavy weight is also lifted together when the article is lifted and lowered. However, there is a drawback that a large-sized actuator is required as a lifting actuator.

In particular, when there is a distance between the processing liquid tank in the processing chamber and the upper partition wall, the vertical member is naturally long, and the larger the vertical distance of the article, the more However, the length of the vertical member is required, the weight of the vertical member becomes heavier, and there is a drawback that a larger actuator is required.

In addition, a rail for the moving vehicle should be installed in the immediate vicinity above the bulkhead, since the distance between the upper end of this vertical member and the moving vehicle is at least the distance corresponding to the vertical movement of the article. However, there were various restrictions in actual implementation.

The present invention is intended to eliminate such conventional drawbacks, and the purpose thereof is to make the opening formed in the partition wall as small as possible, and further to direct the longitudinal direction of the article in the lateral direction of the moving vehicle. It is possible to increase and lower the moving distance of articles without requiring a particularly large actuator while supporting and supporting up and down, and to dispose a rail for a moving vehicle close to the partition wall. The point is to provide a very practical transport facility that is also possible.

[Means for Solving the Problems]

The transfer equipment according to the present invention is provided with an article supporter that supports an article by restricting its inclination with respect to a horizontal plane to a mobile vehicle that can travel along an indoor rail at an external location above the processing chamber that is blocked from the outside by a partition. It is provided in a suspended state so as to pass through the processing chamber along an opening provided in the partition wall below a traveling route of the vehicle, and its characteristic configuration is a main frame connected to the moving vehicle. And a pair of front and rear rod-shaped vertical frames are vertically provided at a distance from each other in the front-rear direction and along the traveling direction of the moving vehicle, and the pair of rod-shaped vertical frames are downwardly moved through the opening of the partition wall. A frame body that hangs down and extends to the left and right is provided at the lower end portion thereof, and a pair of left and right lifting actuators is provided at approximately the middle portion in the front-rear direction of the main frame, and the lifting actuator is also provided. From each other toward the center, then descends downward between the pair of longitudinal frames located in the front and rear, and then separates left and right outside from each other along the frame extending in the left and right directions. According to the above, the article supporter is hung to support the article with its longitudinal direction oriented in the lateral direction of the moving vehicle.

[Action]

In this way, a pair of left and right lifting actuators are provided substantially in the front-rear direction intermediate portion of the main frame connected to the moving vehicle, and the pair of left and right cord-like members are wound and unwound by the lifting actuators to load articles. Since an article support tool that supports the longitudinal direction of the article in the lateral direction of the moving vehicle is moved up and down, a large actuator like the device disclosed in the above publication is required even when the article is moved up and down significantly. Alternatively, it is possible to dispose the indoor rail disposed above and outside the processing chamber close to the partition wall of the processing chamber.

A pair of front and rear rod-shaped vertical frames are vertically provided at a distance from the main frame in the front-rear direction and along the traveling direction of the moving vehicle, and the pair of rod-shaped vertical frames are provided in the opening of the partition wall. A frame body that is hung downwards and extends to the left and right at its lower end, and the pair of left and right cord-like bodies approach each other from the lifting actuator toward the center, and then the pair of vertical frames that are positioned in front and rear Since it is provided so as to descend downward between the spaces, and then to be separated from each other left and right along the frame extending in the left and right, a pair of rod-shaped vertical frames lined up in the front and rear are provided in the opening of the partition wall. , The cord-shaped body located between the pair of rod-shaped vertical frames only passes, and the lateral width of the opening formed in the partition wall can be made as small as possible. For example, the opening is covered with rubber or the like. Covered with In case, it is possible to reduce the installation cost of the cover.

[Effect of device]

As described above, according to the transportation equipment of the present invention, not only a large-sized lifting actuator is not required, but an article can be lifted and lowered in a state in which the longitudinal direction of the article is oriented in the lateral direction of the moving vehicle. It is also possible to raise and lower the goods greatly up and down, and to arrange indoor rails for mobile vehicles in close proximity to the partition walls of the processing chamber, which is particularly restricted both in terms of use and installation. Therefore, it is possible to obtain a very practical transportation facility.

Moreover, since the opening formed in the partition wall need only be narrow enough to allow the pair of rod-shaped vertical frames and the cords to pass through, it is possible to suppress the leakage of the atmosphere from the processing chamber as much as possible. Even when the opening is covered with the cover, the cover installation cost can be kept low.
