Description

  The present invention is installed in a state where an article transport body that travels along a travel path and transports an article between a plurality of cargo cradles, and the travel path is separated from the outside thereof, and the article transport body An intrusion prevention body having an article loading / unloading port for transferring an article to and from the cargo receiving table, a closing position movable to a closed position for closing the article loading / unloading port and an open position for opening the article loading / unloading port The present invention relates to an article conveying facility configured to include a body and a moving operation means for moving the closing body to the closed position and the open position.

Such an article transport facility transports an article to a load receiving platform by an article transport body, and performs an operation such as picking work or transfer by an operator or a work robot on the article transported to the load receiving platform. . In addition, an intrusion prevention body is provided in a state in which the travel path is separated from the outside, and the article insertion / exit opening formed in the intrusion prevention body can be switched between an open state in which the article entry / exit opening is opened and a closed state in which the article entry / exit is closed. By providing the body, the worker is prevented from entering the travel route from the outside, and the article transport body is prevented from coming into contact with the worker.
As a conventional example of such an article conveying facility, the closing body is configured to be movable in the vertical direction, and the moving operation means for moving the closing body supports the upper end portion of the closing body in a suspended manner. Some of the means are supported by a gate-type support frame (see, for example, Patent Document 1).

JP-A-4-292308

However, in the conventional article transport equipment described above, the moving operation means is supported by the gate-shaped support frame, and the upper end portion of the closing body is supported by hanging by the moving operation means, and is closed by the moving operation body. Since the body is moved up and down, a gate-type support frame for supporting the moving operation means must be provided, which increases the manufacturing cost of the closed body when the closed body is installed. It was.
In addition, in order to provide the gate-shaped support frame between the load receiver and the article transport body traveling on the travel route, the support frame is interposed between the article transport body and the load receiver. The cargo cradle was installed at a position away from the travel route in the width direction of the travel route. As a result, when a fork type transfer device is provided on the article transport body, it is necessary to lengthen the fork reach of the transfer device, and in order to ensure load resistance, the rigidity of the transfer device must be increased. In this respect, the cost was high. In particular, the gate-shaped support frame body may have a thicker frame member that constitutes the support frame body in order to firmly support the movement operation means and the closed body supported by the movement operation means. Thus, when the support frame having a thick frame member is provided between the article transport body and the load receiving platform, the load receiving platform must be provided far away from the travel route in the lateral width direction of the travel route.

  The present invention has been made in view of the above circumstances, and its purpose is to be able to install the load receiving stand near the article transport body even if the closed body is installed while the installation cost of the closed body can be suppressed. The object is to provide an article transport facility.

The article transport facility according to the present invention is installed in a state of separating an article transport body that travels along a travel path and transports an article between a plurality of receiving pedestals, and the travel path and the outside thereof, and An intrusion prevention body having an article loading / unloading port for transferring an article between the article receiving body and the article receiving body; a closed position for closing the article loading / unloading opening; and an open position for opening the article loading / unloading opening. And a movable operating means for moving the closed body to the closed position and the open position. The first characteristic configuration is:
The closing body is configured to be movable along the longitudinal direction of the travel path, and the moving operation means supports the lower end portion of the closing body and moves the closing body to the closed position and the open position. It is provided on the floor for operation.

That is, the moving operation means is supported on the floor, the lower end portion of the closing body is supported by the moving operation means, and the closing operation is moved along the travel route by the moving operation body. Since the means is supported on the floor surface, it is not necessary to provide a member for supporting the moving operation means, so that the manufacturing cost can be reduced. In addition, since it is not necessary to provide a member for supporting the movement operation means between the travel route and the load receiving platform, the load receiving platform can be provided close to the travel route.
Therefore, it has become possible to provide an article transporting facility that can install the load receiving stand near the article transporting body even if the closing body is installed while the installation cost of the closing body can be suppressed.

  According to a second characteristic configuration of the article conveying facility according to the present invention, in the first characteristic configuration, the movement operation means is configured by an air-type rodless cylinder provided along a longitudinal direction of the travel path. In the point.

  That is, by configuring the moving operation means with a rodless cylinder, it is not necessary to secure a space for moving the rod, so that the moving operation means can be configured compactly. Further, in general, compressed air can be easily obtained from a compressed air supply line at a place where an article conveyance facility is provided, such as a manufacturing site, so that the pneumatic rodless cylinder can be driven using this compressed air. . Therefore, there is no need to provide a drive means dedicated to the rodless cylinder, and the installation cost of the moving operation device can be suppressed.

  According to a third characteristic configuration of the article conveying facility according to the present invention, in the first or second characteristic configuration, the movement operation unit supports the closing body at a portion on an outer side in a lateral width direction of the travel route. In addition, the inner portion of the travel route in the lateral width direction is provided so as to be positioned in the lower space of the article transporter.

That is, since the moving operation means supports the closing body at the outer side portion where the load receiving table is positioned in the lateral width direction of the travel route, the moving operation means is moved from the closing body to the side where the load receiving table is positioned. Is not protruded or protrudes greatly, and is provided in a state of protruding largely from the closed body on the side where the article transport body is located.
That is, even if the moving operation means cannot be installed in the lower space of the load receiving table due to the presence of the leg portion of the load receiving table, the moving operation means does not protrude from the closed body to the side where the load receiving table is positioned or does not protrude greatly. Since the load receiving platform can be provided near the closed body, the distance between the load receiving platform and the travel route can be reduced. Further, the moving operation means largely protrudes from the closed body to the side where the article transport body is located, but the inner side portion in the lateral width direction of the travel path is provided so as to be located in the lower space of the article transport body. Therefore, the moving operation means can be provided so as not to obstruct the travel of the article transporter.

  A fourth feature configuration of the article transport facility according to the present invention is that, in any one of the first to third feature configurations, the movement operation means is configured to place and support the closing body. is there.

  That is, the moving operation means can stably support the closing body, and the closing operation body is provided in a state in which the closing body is accommodated within the width along the lateral direction of the travel route in the movement operation means. Thus, the size of the travel route in the width direction can be made compact.

  A fifth characteristic configuration of the article transporting facility according to the present invention is any one of the first to fourth characteristic configurations, in which the load receiving table is paired in parallel with a distance along the longitudinal direction of the travel path. The intrusion prevention body is provided with a pair of the article loading / unloading ports in a state of being spaced apart in the longitudinal direction of the travel path corresponding to each of the pair of load receiving tables. A closed body provided for the article outlet on one side in the longitudinal direction, and a fully closed position for closing the entire article outlet, and a full opening on one side in the longitudinal direction from the fully closed position. A single-plate-shaped body that is movable to a position, and a closing body that is provided with respect to the other article insertion / exit port in the longitudinal direction of the pair of article entry / exit ports, The length at the goods outlet A one-side plate-like body that is movable to a partially closed position that closes a portion on one side of the direction and a partially opened position that is located on one side in the longitudinal direction from the partially closed position, and the longitudinal direction of the article insertion / removal port It is configured in a double-opening manner with two plate-like bodies that are movable to a partially closed position for closing the other side portion and a partially opened position located on the other side in the longitudinal direction from this partially closed position. There is in point.

That is, the plate-like body is moved to one side in the lateral width direction to open the article entry / exit port on one side, the one-side plate-like body is moved to one side in the lateral width direction, and the other side plate-like body is moved to the other side in the lateral width direction. Move to open the article loading / unloading port on the other side. That is, when opening a pair of article loading / unloading ports, the plate-shaped body is moved to one side where the other-side article loading / unloading port is not located, and the other side plate-shaped body is moved to the other side where the one-side article loading / unloading port is not located. Therefore, it is only the one-side plate that is moved between the one-side article loading / unloading port and the other-side article loading / unloading port. Therefore, even if both of the pair of article loading / unloading ports are opened, the plate-like bodies do not overlap each other. Therefore, the closed body that closes the one-side article loading / unloading port and the closing body that closes the other-side article loading / unloading port are thick. There is no need to displace in the direction, and the thickness in the width direction of the travel route can be reduced.
And, since the other-side article loading / unloading port is closed by the one-side plate-like body and the other-side plate-like body, it takes less time than the case where the entire article loading / unloading port is closed by a single plate-like body. The goods outlet can be opened and closed.
