[Structure] The fall prevention tool on the upper surface of the trolley 1 is of a link mechanism type that can be remotely operated, and is configured so that it can be opened and closed when loading and unloading the conveyed goods 2. On the other hand, a tumble prevention mooring tool 7 is fixed to the lower surface of the trolley 1 so that it can be fitted into a rail embedded along the traveling direction of the trolley 1. [Effect] Even if the product is long or has a high center of gravity, there is no fear of tipping over and safe and reliable transfer is possible. Transfer is possible easily.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a transfer carriage used when an elongated object is to be automatically processed by an isotropic pressure pressurizing device or the like.

[0002]

[Prior art]

 In recent years, isotropic pressure presses have been shifting from small-scale production machines to large-scale production machines, and the desire for high productivity, high reliability, and high operating rates is increasing.

[0003] Conventionally, a processed material packed in a rubber mold or the like is stored in a transportation basket, and as a transportation object, charging or extraction into a high-pressure container is performed by manual operation using an overhead crane or the like. It was

Moreover, in order to increase the production amount with the existing equipment, the transportation basket is expanded to a size that can be loaded into the high-pressure container, and the amount of processed products stored in the transportation basket is maximized. It was being processed and increased.

However, manual operation by human intervention makes it difficult to secure high productivity and a high operating rate as expected, and also causes a problem in worker safety.

[0006]

[Problems to be solved by the device]

 Not only is it difficult to achieve high productivity, high reliability, and high operation rate in loading / extracting work and cargo handling work by manual intervention using an overhead crane, etc. Highly-conveyed goods have poor stability and have problems in safe transfer.

The present invention intends to completely eliminate the parts that conventionally depended on human power in a large-scale production machine, and to carry out the processing objects by fully automatic operation and to load and extract the high-pressure containers.

[0008]

[Means for solving the problem]

 The present invention has solved the above-mentioned problems, and its gist is to provide a transport carriage configured to allow a long-sized transport object to be placed and to travel, and to prevent the transport cart from falling over. A bogie for transferring a long object characterized in that a stopper and a rail for fall prevention are provided on the ground side, and a mooring tool for fall prevention configured to be movable in the rail is provided on a carriage.

[0009]

[Action and Example]

 Hereinafter, the present invention will be described with reference to an embodiment truck shown in the drawings.

According to the present invention, a pair of front and rear clamp hooks 4 and 4 ′ are installed on the upper surface of the transfer carriage 1 on the side of the object mounting base 3 along the traveling direction of the transfer carriage 1 to provide a clamp foot. The four hooks 4 and 4'are connected to each other via the connecting rod 5, and the clamp hook 4 at one end is connected to the electric cylinder 6 so that the push and pull motion of the electric cylinder 6 opens and closes the hooks 4 and 4 '. The carrying object 2 placed on the transfer carriage 1 is brought into a clamped state X (FIG. 5) or an unclamped state Y (FIG. 6).

Further, a fall-prevention rail 8 is provided along the traveling direction of the transport carriage 1 on the side where the traveling rail of the transport carriage 1 is installed, and the fall-prevention mooring tool is fitted in the rail to prevent the fall. 7, 7 ′ are fixed to the lower surface of the transfer carriage 1.

An embodiment of the present invention will be described below with reference to FIGS.

The articles 2 are loaded on the transfer carriage 1 by the article handling device 11 separately installed.

In this case, the clamp hooks 4 and 4 ′ of the link mechanism type fall prevention tool on the upper surface of the transfer carriage 1 are set in the unclamped state Y in advance.

That is, the pulling operation of the electric cylinder 6 causes the clamp hook 4 to rotate downward, and the movement also causes the clamp hook 4 ′ to rotate via the connecting rod 5 to bring it into the unclamp state Y.

Next, the handling device 11 mounts the transported object 2 on the transported object mounting base 3 surface on the upper surface of the transfer carriage 1, and the electric cylinder 6 is driven by the signal of the mounting detection of the presence detector 9. To move the clamp hooks 4 and 4'upward so that the conveyed object 2 is in the clamped state X.

The position detectors 10 and 10 ′ are used for confirming the operation of the clamp hooks 4 and 4 ′, and the clamp state X described above is used after the position detector 10 ′ and the presence detector 9 are operated. The suspended state of the transported object handling device 11 is released.

That is, after the transfer object 1 that hits the tray of the transfer object 2 is reliably placed and held on the transfer object 2, the lifting hook portion 12 of the transfer object handling device 11 is released.

Next, after the lifting hook portion 12 of the conveyed material handling device 11 is completely retracted upward, the transfer carriage 1 is run to a predetermined position.

In this case, the transported object 2 can be clamped on the upper surface of the transfer cart 1, and the cart itself is provided with the tumble-prevention mooring tools 7, 7'for the tectonic-prevention rail 8 on the traveling base surface. As a result, even if the vehicle is run / stopped at a rapid acceleration / deceleration, the object can be achieved safely and surely without causing the transfer carriage 1 and the conveyed object 2 to fall.

After being transferred to a predetermined position, the transported object 2 is handled by using the transported object handling device 11. At this time as well, the lifting hook portion 12 of the handling device 11 is surely handled in the same manner as described above. After reaching the position for gripping, the transported object clamping mechanism on the upper surface of the transfer carriage 1 is set to the unclamped state Y, and the transported object handling device 11 is lifted and activated by the signal of the position detector 10.

When the processing of the conveyed object 2 in the high-pressure container or the like is completed, the conveyed object 2 is loaded on the transfer carriage 1 by the reverse operation procedure up to that point, and is moved to the dispensing position again to perform a series of one cycle operation. Is completed.

In this way, when delivering the conveyed article 2 to the transfer carriage 1 or delivering the conveyed article 2 from the same carriage 1, the clamping of the conveyed article 2 is surely completed and the process proceeds to the next step. Since the body is prevented from falling when the carriage 1 travels, it is possible to ensure that the object 2 itself is long or the center of gravity is at a high position and handling is extremely unstable. It is possible to transfer.

In the embodiment of the present invention, the link mechanism type clamp device on the upper surface of the transfer carriage 1 is described to operate by the electric cylinder 6, but a hydraulic cylinder, a pneumatic cylinder or another actuator is applied. It is also possible to do it easily.

Therefore, the present invention is not limited to the type of actuator such as an electric cylinder.

[0026]

[Effect of device]

 According to the present invention, because of the above-mentioned configuration, even if the transported object itself is long or the center of gravity is at a high position and the handling is extremely unstable, it is possible to prevent the fall. Can be transferred.

In this way, the purpose can be achieved more than adequately only by applying the compact and simple constituent devices, and the transported objects of any shape can be reliably transferred without falling, which is also safe. It is possible to prevent damage due to poor handling.

Further, since the transfer work can be carried out reliably and accurately, it is possible to easily cope with fully automatic operation, greatly contribute to labor saving, and the contribution in terms of safety and economy is immeasurable. There is something.
