Abstract

PURPOSE:To regulate the loading surface and the load placing surface of a platen parallel, and to prevent a drop or a collapse of a baggage at the time of loading or unloading, by providing a rotation mechanism to rotate the platen around a rotary shaft whose face plate moving direction is made in the axial direction. CONSTITUTION:When numerous rice bags are loaded on a platen 20 or unloaded from the platen 20 in a cargo work, and when the load placing surface or the like is inclined, the operator operates a hydraulic mechanism to operate a cylinder 19. In this case, when the load placing surface is inclined to the left side, for example, the operation oil is fed to the cylinder 19 to extend a cylinder rod to turn a finger bar 13 in the direction of the arrow A. Since the finger bar 13 turns making a fulcrum pin 14 as the center while being guided by slide guides 17a and 17b, in this case, the load placing surface and the loading surface 20a are made almost parallel by regulating the feeding amount of the operation oil to the cylinder 19 by the operator. A drop or a collapse of the baggage is not generated consequently.

Two platens 4 (one shown) are attached to the finger bar 3, and the platen 4 has a wide loading surface 4a that projects forward from the finger bar 3 and is used to load cargo.

Also, although not detailed, a face plate is attached to the finger bar 3, and this plate is attached to the platen 4.
It is possible to move forward and backward along the loading surface of the platen 4 and push out the cargo loaded on the platen 4 forward.

The load/push-pull device with such a configuration holds one end of a sheet-like pallet loaded with a large number of bags containing rice, wheat, etc. (hereinafter referred to as rice bags) between the face plates, and pulls it toward the finger bar. The rice bags are placed on the loading surface 4a of the platen 4, placed on top of the rice bags placed elsewhere, and the face plate is pushed forward to stack the rice bags from the platen 4 on top of the rice bags. .

(Problems to be Solved by the Invention) However, in such a conventional load/push-pull device, the rice bags are still not stable in shape and cannot be stacked in parallel, and the platen 4 is not connected to the rotation plate. 2 and the finger bar 3, the forklift was fixed to the cargo handling carriage l via the finger bar 3.
When the load loaded on the platen 4 is tilted or the loading surface is slanted, it may be difficult to remove the load from the platen 4, or the load may be dropped during loading. In particular, since the loading surface 4a of the platen 4 is formed with a large width, it is important that the loading surface 4a be parallel to the loading surface 4a. There was a problem in that the cargo handling work became difficult due to the cargo becoming unstuck or collapsing.

(Purpose of the Invention) Therefore, the present invention makes the platen rotatable to adjust the loading surface and cargo storage surface of the platen parallel to each other, thereby preventing the cargo from being damaged and improving the workability of cargo handling work. The aim is to improve.

(Means for Solving the Problems) In order to achieve the above object, the load bush pull device according to the present invention includes a cargo handling carriage provided in the mast so as to be movable up and down, and a finger attached to the carriage via a rotation plate. a bar; a platen that is attached to the finger bar and has a wide loading surface that protrudes forward from the bar to load cargo; A load/push-pull device comprising a face plate capable of pushing loaded cargo forward, including a rotation mechanism for rotating the platen around a rotation axis whose axial direction is the direction of movement of the face plate. It is characterized by

(Function) In the present invention, a rotation mechanism is provided that rotates the platen around a rotation wheel whose axial direction is the moving direction of the face plate. Therefore, the loading surface of the platen and the cargo storage surface can be made parallel to each other, preventing the cargo from falling during loading and unloading.
This prevents it from collapsing. As a result, damage to the cargo is prevented and the workability of cargo handling operations is improved.

(Example) Hereinafter, the present invention will be explained based on the drawings.

1 to 4 are diagrams showing an embodiment of the load/push-pull device according to the present invention.

First, the configuration will be explained. In FIG. 1, reference numeral 11 denotes a carriage, and the carriage 11 is mounted on a mast of a cargo handling vehicle (not shown) so as to be movable up and down. This carriage 11
A finger bar 13 is attached to the rotation plate 12 via a rotation plate 12, and the finger bar 13 is rotatably attached to the rotation plate 12 via a fulcrum pin 14, a snumb ring 15, and a bearing 16, as shown in FIG. It is being Also, finger bar 1
3 has slits 13a and 13b formed therein, and this slit 13a.

Slide guides 17a and 17b are embedded in the slide guide 13b such that a predetermined gap is formed between each end and the slide guides 17a and 17b. The slide guides F17a, 17b are fixed to the rotation play eye 2 by bolts 18 as shown in FIG. Rotation plate 1
2 is prevented from rotating more than necessary. Also, rotation play number 2 and finger bar 13
A cylinder 19 is interposed between the two as shown in FIG.
b is fixed to the finger bar 13. cylinder 1
9 is connected to, for example, a hydraulic mechanism (not shown), and the reference point of the cylinder rod 19c (
The finger bar 13 is rotated about the fulcrum pin 14 by expanding and contracting from the neutral position. Further, two platens 20 (one not shown) are attached to the finger bar 13, and the platen 20 has a loading surface 20a that protrudes forward from the finger bar 13 and loads cargo,
The loading surface 20a is formed to have a large width so that a large number of relatively soft items such as rice can be loaded thereon. Further, although not shown, a face plate is attached to the finger bar 13, and this plate moves in the front and back direction along the loading surface 20a of the platen 20 to push the load loaded on the platen 20 forward. It is composed of

The above-mentioned fulcrum pin 14, bearing 16, slide guides 17a, 17b and cylinder 19 are connected to the platen 20.

Next, the effect will be explained.

When loading a large number of rice bags onto the platen 20 or unloading the rice bags from the platen 20 during cargo handling work, the driver operates the hydraulic mechanism to operate the cylinder 19 when the cargo loading surface is inclined. At this time, for example, if the loading surface is inclined to the left, hydraulic oil is supplied to the cylinder 19 to extend the cylinder rod 19c and rotate the finger bar 13 in the direction of arrow A. At this time, the finger bar 13 rotates around the fulcrum pin 14 while being guided by the slide guides 17a and 17b, so when the operator adjusts the amount of hydraulic oil supplied to the cylinder 19, the picking surface and the loading surface 20a are aligned. become almost parallel. Therefore, when loading cargo onto the platen 20, the cargo does not fall or collapse, and the cargo can be handled smoothly.
It is possible to prevent cargo from being damaged and to improve the efficiency of cargo handling work.

Furthermore, in this embodiment, since the amount of rotation of the finger bar 13 is regulated by the slide guides 17a and 17b,
It is possible to prevent the cylinder 19 from rotating more than necessary and the cargo falling from the platen 20.
