Abstract

PURPOSE:To make separation of stacked racks so easily by attaching a separate device, provided with a fixed fork and a movable fork free of lifting motion to this fixed fork, to a front plate free of lifting and symmetrically sliding motion. CONSTITUTION:A front plate 5 slidable in both directions is attached to a carriage 2 liftable on a mast 1, and a separate device 8 provided with a fixed fork 7 and a movable fork 25 liftable to the former are attached to the front plate 5. At the time of operation this separate device is inserted into an interval between a lowermost stage rack a1 where the fixed fork 7 and the movable fork 25 are made to be flush with each other and a next stage rack a2. Then, it is uplifted up to height of the rack a1, but the movable fork 25 is pressed down, thus the lowermost stage rack a1 is separated. With this operation repeated, stacked racks are separated piece by piece by a driver alone.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a forklift attachment, which is used to store long objects stored in piles.
・! This is used to separate the particles one by one.

[Prior art 1, rack a for storing long steel materials and other long objects
, a rectangular structural member C with multiple pillars erected.
It is known that legs d are attached to the required places on the racks, and hooks f are attached to the required places on the pillars (see Figure 5).In order to store this rack a, as shown in Figure 6, , a plurality of racks a1 to aN are sequentially shifted and stacked in several rows (5 rows in FIG. 6), and then stacked in several rows (6th row).
It is customary to stack them in four stages (in the figure) and store them in a pile.

Due to their shape and weight, the racks stored in this pile become intertwined with each other, making it extremely difficult to take them out one by one.

Normally, the fork of a forklift is placed in the lowest rack a.
Insert the stack of racks between E and the rack A2 directly above it, and lift the stack of racks to a height of about 1 m above the ground.The worker then uses a hammer to tap the lowest rack A to the left and right below to disentangle it and allow it to fall to the ground. After that, the pile of racks remaining on the fork is lowered to the ground, and the same process is repeated to separate them one by one.

[Problems to be Solved by the Invention] The conventional work method using a forklift requires at least two workers, and not only is the efficiency of fj work inefficient, but it is especially difficult to perform hammer work to remove entanglements. The problem was that the workers were forced to do hard labor, which resulted in severe fatigue.

The present invention aims to solve the above-mentioned problems, and provides a device that allows only a forklift driver to separate and take out racks piled up one by one.

[Means for Solving the Problems 1] The present invention provides means for solving problems L, and claim 1) provides a carriage 2 that can be freely slidable left and right along a mast 1. A 7t equipped with a separating device characterized in that a separating device 8 comprising a fixed fork 7 and a movable fork 25 minutes that can be raised and lowered relative to the fixed fork 7 is attached to a front plate 5 supported by a front plate 5. Claim 2) is based on a crit, and claims 2) provides a front plate 5 that is supported by a carriage 2 that can be raised and lowered along a mast 1 so as to be slidable left and right, and a fixed frame 7 and a fixed fork 7 that can be raised and lowered with respect to the fixed fork 7. Attaching the separation device 8 equipped with a freely movable fork 25,
The gist of this forklift is a forklift equipped with a rack separation device characterized in that a guide piece 9 having a guide slope 9a is housed outside a fixed fork 7 at an interval of Flr.

[Example] The structure of the present invention will be explained with reference to an example shown in the drawings.

A front grate 5 is attached to a carriage 2 that moves up and down along a mast 1 via a wear strip 3 and a liner 4.

The front plate 5 is slidable left and right by side cylinders 6. A separate device W8 is attached to the front plate 5, which includes a fixed fork 7 and a movable fork 25 that can be raised and lowered relative to the fixed fork 7.

Reference numeral 9 denotes a guide piece 9 equipped with a guide slope 9a for guiding the fall of the separated rack F, and a front plate 5 is placed on both sides of the direct fixed fork 7 at a required interval.
The spacing between the left and right guide pieces is approximately equal to the spacing between the pillars of rack a.

Here, the structure of the separation device 8 for raising and lowering the movable fork 25 will be described in detail.

1.0.11 is a pair of left and right guide rails installed facing each other, and a horizontally installed top cross member 12.
Middle cross member 13. lower cross member 14
They form a single tree and form a separate structure)〃8.

An upper hook 15 is housed in the middle cross member 13, and the separation device 8 is mounted on the front plate 5 by hooking the upper hook 15 on the front plate 5.

A vertical center cross member 16 connecting the top cross member 12 and middle cross member 13 is provided at the center of the separation device 8, and a cylinder bracket 1 is provided to protrude from the center cross member 16.
7, the bottom side of one separate cylinder is housed through a bottle 18.

On the other hand, the rod side of the separate cylinder 19 is attached to a cylinder bracket 22 protruding from a cross member 21 of the carrier 20 via a pin 23.

The carrier 20 is attached to the guide rail 10.11 via rollers 24, and by expanding and contracting one separate cylinder, the carrier 20 is moved up and down along the guide rail 10.11. .

A movable fork 25 is fixed to the cross member 21 of the carrier 20, and is movable up and down together with the carrier 20.

When the separator cylinder 19 is in the most contracted state, the upper surface of the movable fork 25 and the upper surface of the fixed fork 7 are on the same plane as shown by the solid line, and when one separator cylinder is in the most extended state, the upper surface of the movable fork 25 and the upper surface of the fixed fork 7 are on the same plane, as shown by the two-dot chain line. As shown, the movable fork 25 is configured to move downward to the A position.

[For Cattle] Since this invention has the configuration shown in E, it operates as follows to separate the racks.

First, one separate cylinder is contracted to its maximum length so that the upper surface of the movable fork 25 and the upper surface of the fixed fork 7 are at the same height, and the highest stage rack a1 and the rack a2 stacked directly above it are
Insert it between.

Next, the mast 1 is raised until the height of the upper surface of the fixed fork 7 above the ground becomes approximately equal to the height H of the rack a.

In this state, when one separate cylinder is extended and the movable fork 25 is pushed down, the movable fork 25 pushes down the horizontal member C of the rack a, so the lowest rack a1 is forcibly separated. The remaining hooks a2 to a6 will remain supported on the fixed fork 7.

Then, the separate cylinder 19 is contracted again to the maximum length so that the movable fork 25 and the fixed fork 7 are at the same height, and then the forklift is moved backward. The mast 1 is lowered and the racks a2 to a remaining in the fixed hook L are placed on the ground.

After moving the forklift further backward and removing the fixed fork 7 and movable fork 25 from the Y, move the mast 1 to L.
Adjust the height of hook 7.25 by raising it slightly, and then separate rack a2, which is now the lowest rack, in the same manner as above.

You can separate racks one after another.

Further, according to the invention of claim 2, a guide piece 9 having an inclined surface 9a is provided on the outside and side of the fixed fork 7 at an interval approximately equal to the interval between the pillars of the rack a. , place the fork 7.25 on the lowest rack AL and its direct E
As shown in FIG. If the lowermost rack a falls, the hook f will be guided by the slope 9a of the guide piece 9 and fall, so the ljd of rack a2 will be straightened.
It can prevent you from getting caught.

Note that in order to facilitate this positioning, a side shift mechanism can be housed in the front plate 5.

[Effects] According to the invention of claim 1), the movable fork 25 that can be raised and lowered relative to the fixed fork 7 is disposed inside the fixed fork 7, so that both forks can be connected to the lowermost rack al and the rack immediately above it. a2 and can be separated by the movable fork 25, it is possible to separate and take out the stacked racks one by one only by the driver of the forklift. According to the invention of 2), by disposing the guide piece 9 having the guide slope 9a at a required interval on the outside of the fixed fork 7, it is possible to guide the rack that separates and falls. There is an effect that the hook f of the lower rack a1 can be smoothly separated without being caught by the ill d of the straight hook a2.
