Description

[Detailed description of the invention] [Field of industrial application] The present invention is an attachment for a push-pull device that handles cargo using sheet pallets, and the present invention is a push-pull device that makes it possible to properly grip and fix the gripping portion (tab portion) of the sheet pallet. Regarding attachments for use.

[Conventional technology]

In recent years, the use of sheet pallets has rapidly become popular as a method of carrying out cargo handling operations.

In this method, a forklift truck equipped with a push-pull device is used to grab a load on a thin, flexible sheet pallet by gripping the tabs of the sheet pallet using a gripper device that is movable in the front and back direction and is equipped with an attachment for the push-pull device. This is a cargo handling method in which the cargo is held and fixed, and the push/pull operation is performed on the platen of a push/pull device.

In this method, the gripper device included in the push-pull device attachment is movable in the front and back direction using a hydraulic cylinder, a pantolink mechanism, etc. ) is difficult to stop accurately. Therefore, the tab of the sheet pallet often enters too deeply into the gripper (excessive penetration), resulting in stoppage of cargo handling and conveyance operations, damage to the sheet pallet, or time-consuming work to correct the gripping part (tab part), which greatly reduces work efficiency. This has the problem of lowering the amount of energy.

[The problem that the invention is intended to solve]

The present invention overcomes the above-mentioned problems and uses sheet pallets to prevent excessive gripping of sheet pallets when carrying out cargo handling operations with a forklift truck equipped with a push/pull device, thereby preventing the loading and unloading operations from being stopped and the sheet pallets being moved. The purpose of this is to improve work efficiency by eliminating the need to repair damaged or properly gripped parts (sheet pallet tab parts).

[Means for solving problems]

The present invention relates to an attachment for a push-pull device for handling cargo using sheet pallets, which is characterized in that a stopper 12 is provided in the channel 6c of the gripper device 6 of the gripper device 6, which includes a gripper rod 6b and a gripper yaw 6a. This is an attachment for push-pull devices.

[Example] Next, the present invention will be described by way of an example with reference to the drawings.

FIG. 1 shows a schematic diagram of a push-pull device.

The push-pull device attachment 1 includes a frame 2 that is generally attached to a mast so as to be able to be raised and lowered;
a platen 3 fixed to the lower part of the frame 2;
A face plate 5 that is extendable and retractable in the front and rear directions along the platen 3 using the frame 2 as a base by a pantolink mechanism 4; It is equipped with a gripper mechanism 6 and a sheet pallet holding device 7 which are movable.

FIG. 2a shows an enlarged view of the gripper device of the present invention, and FIG. 2b shows an enlarged view of the conventional gripper device. That is, the gripper device 6 attached to the attachment 1 is composed of a gripper yaw 6a and a gripper rod 6b, and the gripper rod 6b is movable and extended up and down by a hydraulic cylinder 6d, and can grip and fix the sheet pallet 10. As shown in the figure, when gripping and fixing the sheet pallet 10, it is difficult to accurately stop and grip the gripper device at a predetermined position (tab portion of the sheet pallet), and the leading end of the sheet pallet is often attached to the channel 6c at the top of the gripper yaw. It is customary for the sheet to be extended upwards, causing problems such as damage to the sheet pallet due to the tabs being pushed in too much, or troubles such as troublesome work being done to correct the tab portions.

However, as in the present invention of FIG. 2a, the channel 6 of the gripper yaw 6a of the gripper device 6
By providing a stopper 12 to prevent the sheet pallet from digging in at c, even if the gripper device brakes excessively, the tab end of the sheet pallet will come into contact with the stopper 12, preventing the sheet pallet from digging into the gripper, and ensuring that the sheet pallet is not wedged into the grip properly. It is possible to grip and fix it with.

Further, in order to further reduce damage to the end portions of the sheet pallet, it is preferable that the stopper 12 be covered or constructed with a cushioning material such as plastic or rubber.

In this way, if the sheet pallet is not gripped and fixed to the tabs, it may not be possible to carry out cargo handling operations smoothly, and in severe cases, the load may collapse, or the sheet pallet may be damaged because it is gripped and fixed by something other than the tabs. A number of problems arise, including significantly shortening the life of the sheet pallet.

[Function and effect of the idea]

As explained above, the present invention prevents excessive jamming of sheet pallets by providing a stopper in the upper channel of the gripper yaw of the gripper device attached to the attachment of a push-pull device that handles and transports sheet pallets. However, since the sheet pallet can be gripped and fixed within the appropriate tab portion of the sheet pallet, cargo handling and conveyance operations can be carried out smoothly and efficiently.

In addition, since excessive digging can be prevented, problems such as damage to the tab ends due to impact when gripping the sheet pallet with the gripper device can be eliminated.
