Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a seat pallet for a cargo-handling vehicle with a push-pull in which a face provided with a seat gripper is provided so as to be movable in the front-rear direction along a fork claw that moves up and down.

[Conventional technology]

As a cargo handling vehicle with push-pull, for example, the one shown in FIG. 11 is known.

That is, a fork claw c is provided so as to be able to move up and down along a mast b provided on the front part of the vehicle body a, and a face e having a seat gripper d is provided along the fork claw movably in the front-rear direction. To the forward position to move the load A
The tab B'of the sheet pallet B laid underneath is grasped by the sheet gripper d, the vehicle body a is moved forward while the face e is moved backward to the front position, and the load A is pulled onto the fork claw c together with the sheet pallet B. In the state where the sheet gripper d releases the grip of the sheet pallet B, the face e is moved forward to the front position and the vehicle body is moved backward to move the load A together with the sheet pallet B along the fork claws c. A cargo-handling vehicle with push-pull that pushes out to the side and loads the work.

[Problems to be solved by the device]

In order to carry out cargo handling work in such a push-pull cargo handling vehicle, it is necessary to place pre-loaded loads on the sheet pallets and stack them. Instead, all work is done manually, and manually re-loading a number of loads onto a sheet pallet is a great effort.

Then, this invention aims at providing the seat pallet of the cargo handling vehicle with a push pull which was able to solve the above-mentioned subject.

[Means and Actions for Solving the Problems]

Plate-shaped sheet pallet body 40 Vertical piece 30a and horizontal piece 30b at the front edge
Of a cargo handling vehicle with a push-pull in which an L-shaped hook 30 is provided and a fork claw insertion concave portion 33 opening toward the rear edge is formed between the hook 30 and the lower surface of the sheet pallet body 40 near the front edge. This is a sheet pallet, and with this, the sheet pallet is placed on the fork claw and the tip of the fork claw is fitted in the fork claw insertion concave portion 33, and the fork claw is used to load the sheets stacked in advance. You can insert it in between.

〔Example〕

As shown in FIG. 3, a pair of left and right fork claws 11 and 11 are provided on the lifting body 10 that moves up and down along the mast of the vehicle body (not shown), and the lifting body 10 has a U-shaped cross section. A pair of left and right frames provided with a pair of guide rails 12 and having a U-shaped cross section along each frame 12.
13 and 13 are provided so as to be able to move up and down, and an elevating mechanism 14 is provided across the frame 13 and the guide rail 12, and a pair of left and right seat retainers 15 and 15 are provided below the pair of left and right frames 13 and 13. The face 17 is provided so as to face the fork pawl 11, and a face 17 is provided on the pair of left and right frames 13, 13 so as to be movable back and forth along the fork pawl 11 by a moving mechanism 16.

The moving mechanism 16 is provided with a pair of left and right first and second telescopic links 18, 18, 19, 19 which are telescopically operated by a cylinder (not shown) or the like. The member 20 and the lower horizontal member 17a of the face 17 are pivotally attached, and both ends of the second expansion link 19 are slidably supported along the frame 13 and the vertical member 17b of the face 17.

A sheet gripper 23 having a sheet receiver 21 and a presser piece 22 is provided below the face 17, and the presser piece 22 holds the sheet pallet B by a cylinder or the like (not shown).
The horizontal piece 21a is pressed and grasped and released.

As shown in FIG. 3, the lifting mechanism 14 is provided with a horizontal plate 24 on the upper portion of the frame 13, and a nut 25 is provided on the horizontal plate 24.
An electric motor 26 is provided on the guide rail 12, and a screw 28 is connected to the output side of the electric motor 26 via a speed reducer 27.
28 is screwed to the nut 25 and protrudes upward from the horizontal plate 24, so that the frame 13 moves up and down along the guide rail 12 by driving the electric motor 26 forward and backward to rotate the screw 28 forward and backward. I am doing it.

The horizontal plate 24 is laid horizontally between the left and right frames 13, 13 so that the left and right frames 13, 13 ascend and descend in synchronization.

As shown in FIGS. 1 and 2, the sheet pallet B has a tab B ′ formed at the rear edge of the sheet pallet body 40 in the form of a rectangular plate, and the tab B ′ is formed on the lower surface of the front edge of the sheet pallet body 40. A hook 30 is provided.

The hook 30 is formed by notching the front end edge of the sheet pallet body 40 in a substantially U-shape, and punching out a portion 32 surrounded by the notch 31 into a substantially L-shape.
The vertical piece 30a and the horizontal piece 30b form a substantially L-shape, and the hook 30 and the lower surface of the sheet pallet body 40 near the front edge form a fork claw insertion recess 33 that opens toward the rear edge. 4 Fork claw 11 on the sheet pallet B as shown in the figure.
When placed on the top, the tip 11a of the fork claw 11 is fitted in the fork claw insertion recess 33.

Because of this, the sheet pallet B is pushed together with the fork claws 11 between the pre-stacked loads A as shown in FIG. 5 (a), and the sheet pallet B is moved as shown in FIG. 5 (b). When the fork claw 11 is pushed backward to a predetermined position, the fork claws 11 are moved backward and pulled out from between the loads A, whereby the sheet pallet B remains between the loads A as shown in FIG. The sheet pallet B can be laid between the loads A using the fork claws 11.

At this time, since the hook 30 is interposed between the loads A and pushed by the weight of the loads, the hook 30 is elastically deformed to the original state and the sheet pallet B becomes flat, and the height of the stacked loads is increased. Not only does not become too expensive, but also sheet pallet B
It is not necessary to project the load sideways from the stacked loads.

Therefore, fork claws 11 of a cargo handling vehicle with push-pull
The sheet pallet B can be laid between the loads A preliminarily stacked by using, and the work can be performed without manually reloading the sheets on the sheet pallet.

The hook 30 is, as shown in FIG. 6, FIG. 7 and FIG.
Fold the front edge of the sheet pallet body 40 downwards
It may be formed in an L-shape with a and the horizontal piece 30b. In this way, as shown in FIG. Since the seat pallet B can be attached to the fork claw 11 by fitting it into the front end portion 11a of Fig. 10, Figs. 10 (a), (b), (c)
The sheet pallet B can be laid between the stacked loads A as shown in FIG.

In this case, the sheet pallet B is inserted between the loads A by the fork claws 11 until the hook 30 projects laterally from the loads A.

When the sheet pallet B is laid as described above, the tab B of the sheet pallet B is grasped by the sheet gripper 14 and moved a little upward together with the fork claws 11 to move the sheet pallet B downward. After a slight distance from the load A, the same operation as in the conventional method may be performed.

[Effect of device]

While placing the sheet pallet B on the fork claw 11,
With the tip 11a of the fork pawl 11 fitted in the fork pawl insertion recess 33, insert the sheet pallet B between the stacked loads A together with the fork pawl, insert it to a predetermined position, and then pull out the fork pawl 11. Thus, the sheet pallets B can be laid between the stacked loads A.

Therefore, the fork claw 11 is placed under the pre-stacked load A.
Since the sheet pallet B can be laid by using the sheet pallet, it is not necessary to manually reload the stacked pallets on the sheet pallet, and the work is simplified.
