Description

[Detailed Description of the Invention] The present invention relates to a simple-structured and portable cargo handling loader for pallets that can easily transport pallets loaded with cargo.

As a loader of this kind, the present applicant has constructed a loader main body consisting of a single receiving frame inserted into a pallet and an operating frame connected to the rear end of the receiving frame, and is provided with a front wheel support arm protruding from the front surface of the cargo receiving frame, and a rear wheel support arm on the operating frame, which can be raised and lowered, respectively,
Both support arms are interlocked and connected to an operation handle provided on the operation frame through an interlocking mechanism, and the operation of the handle causes the support arms to rise and fall, thereby raising and lowering the loader body. proposed.

The present invention improves the loader described above, and can transport cargo stably. Especially when double-sided pallets are used,
To provide a cargo handling loader which has a simple structure and is easy to handle, capable of easily grounding the next pallet adjacent to the pallet that has previously been loaded and transported.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.The loader main body 1 is formed of an operating frame 2, and an elongated cargo receiving frame 3 in the shape of a hawk claw, which extends forward and approximately horizontally from the front end of the operating frame. This cargo receiving frame 3 is formed in a U-shaped cross section with an open bottom surface, and a boundary between the cargo receiving surface 4 on the upper surface and the operation frame 2 is provided with abutting end surfaces of a pallet P1 and a cargo, which will be described later. A stopper surface 5 is formed that can prevent these from moving backward.

The receiving frame 3 is formed in a size that allows it to be inserted into a gap C formed in the double-sided pallet P1.

In the operation frame 2 of the loader main body 1, an intermediate portion of the operation member 6 is swingably supported by a shaft 7, and the upper part of the operation member 6 protrudes from an opening 8 of the operation frame 2.

The operating member 6 is provided with a handle insertion hole 9 that opens upward, and an operating handle 10 is inserted into and removed from the handle insertion hole 9.

Further, on the operation frame 2, a rear wheel support arm 13 on which a rear running wheel 11 such as a caster is mounted is rotatably supported by a shaft 14 so that it can be raised or lowered.
Both ends of an interlocking link 150 as an interlocking member are connected with pins between the base end of the operating member 6 and the intermediate portion of the operating member 6.

Also, at the lower end of the operating member 6 is an interlocking rod 16 as an interlocking member.
One end is connected with a pin, and this interlocking rod 16 extends forward inside the cargo receiving frame 3, and the other end is connected to the cargo receiving frame 3 of the loader main body 1.
A shaft 19 is rotatably provided at the outer end so that it can be stood up or laid down.
The front wheel support arm 180 is connected by a pin to the base end of a front wheel support arm 180 supported by the front wheel support arm 180, and the front running wheel 17 is mounted on a shaft at the end of the front wheel support arm 18 that projects from the front surface of the cargo receiving frame 3.

The front wheel support arm 18 is formed by bending into an arch shape between the shaft 19 and the rotating shaft 17a of the front running wheel 17, and when the pallets described later are brought into contact with each other and grounded by this bent portion, This allows the front running wheels 17 to enter into the previously transported pallet.

The distance between the rotating shaft 17a of the front running wheel 17 and the shaft 19 is formed longer than the distance between the rotating shaft 11a of the rear running wheel 11 and the shaft 14, so that the front wheel supporting arm 18 can be erected. In this state, the loader main body 1 can be held at a downward slope from the cargo receiving frame side toward the operation frame side, that is, it can be held at a slope upward from the front.

The operating member 6, the interlocking link 15, and the interlocking rod 16 constitute an interlocking mechanism (3) of the present invention that interlocks and connects both support arms 18, 13 to the operating handle 10, and also supports the front and rear wheels. The arms 18 and 13 constitute the front upward tilting mechanism M of the present invention, which is attached to the interlocking mechanism 1 and tilts the loader body 1 upward when the loader body 1 rises.

A hollow cylindrical handle support hole 20 with an open top is provided at the base of the loader body 10, into which the lower end of the handle 10 removed from the handle insertion hole 9 is inserted. For example, its operation: the handle 10 can be held substantially upright as shown by the chain line in FIG.

Next, the operation of one embodiment of the present invention will be described. Normally, a pair of pallet carriers of the present invention are used to lift and transport the double-sided pallet P1 loaded with cargo, and the As shown in the figure, the receiving frames 3 of the pair of pallet carriers are inserted into the gap C of the double-sided pallet Pl.

Next, when the operating handle 10 is swung in the direction of arrow A in FIG. 1 and tilted as shown in FIG. At the same time, the interlocking rod 16 is pushed out to the left, and the front wheel support arm 18 can be rotated counterclockwise and erected.

In this case, the cargo receiving frame side is higher than the operating frame side due to the difference in the distance between the axes, so the double-sided pallet hpi and the cargo receiving frame 3 are both lifted forward and upward from the ground plane, and the gravity of the cargo is placed on the operating frame side. In addition, the front and rear running wheels 17 and 11 can stably support and transport the luggage.

Incidentally, the tilting of the operating handle 10 is regulated by the upper part of the operating member 6 coming into contact with the rear edge 8b of the opening 8.

After the above-mentioned transportation, when the double-sided pallet P1 is placed adjacent to the previously transported double-sided pallet P2 and touches the ground, the front running wheels 17 are moved into the double-sided pallet P2 as shown in FIG. Bring p1 into contact with P2.

In this case, the center of gravity of the cargo on the double-sided pallet Pl is shaded to the operation frame side, and the front wheel support arm 18 is bent into an arched shape so that it does not interfere with the double-sided pallet P2, so the front running wheels 17 are mounted on the double-sided pallet P1. Easily climbs onto the face plate of P2 and enters smoothly.

Then, if the operating handle 10 is swung in the direction shown in the second figure,
The front and rear wheel support arms 18.13 can be rotated upside down to bring the double-sided pallet ()Pi into contact with the ground adjacent to the double-sided pallet (P2).

Note that the front upward tilting mechanism M for tilting the loader main body 1 forward upward can also be configured by a hydraulic cylinder, a screw, a lever, or the like.

Furthermore, in the above embodiment, a case was explained in which a pair of cargo handling loaders were used, but when the cargo is lightweight, one loader is used.
-If the sword baggage is heavy, three or more units may be used.

As described above, according to the present invention, the reloader main body 1 consists of a single cargo receiving frame 3 inserted into the pallet Pl, and the operation frame 2 connected to the rear end of the cargo receiving frame 3, and Receiving frame 3
A front wheel support arm 18 protruding from the front surface of the cargo receiving frame 3 is provided at the front of the cargo receiving frame 3, and a rear wheel support arm 13 is provided on the operation frame 2 so that the rear wheel support arm 13 can be raised and lowered. (2) is interlockingly connected to an operating handle 10 provided on the operating frame 2, and by operating the operating handle 10, the supporting arms 18, 13 are actuated to raise and lower the loader body 12. In the cargo handling loader, the interlocking mechanism (1) includes a front upward tilting mechanism M that tilts the loader body 1 forward when the loader body 1 rises.
A stopper surface 5 is provided at the boundary between the operation frame 2 and the cargo receiving frame 3, which can restrict the rearward movement of the pallet P□ and the luggage placed on the upper surface of the pallet P□. Therefore, when the loader main body 1 is raised, the center of gravity of the pallet P1 and the load is moved rearward by the upper surface of the receiving frame 3, which is a front upward slope, to the front of the pallet P1 and the load. On the other hand, the stopper surface 5 can prevent the pallet Pl and the cargo from moving backwards. Therefore, even during the movement of the cargo handling loader, the pallet P□ and the cargo can be prevented from moving backwards. The pallet can be stably held in a predetermined position on the cargo receiving frame 3 without blindly moving back and forth. Furthermore, since there is no need to provide special means for restricting the advance of the pallet P1 and the like on the receiving frame 3, the structure is simpler, the cost can be reduced, and the handling is easier.

Furthermore, when the loader main body 1 is raised, the centers of gravity of the pallet P1 and the luggage rack move rearward as described above, so the weight of the luggage rack, etc. acting on the front wheels 17 can be reduced, and therefore, for example, when transporting Even in the case where the front wheel support arm 18 is moved into the original double-sided pallet (P2) in order to bring the inner pallet P1 into contact with the other double-sided pallet P2 that was transported earlier, the front wheel 17 The double-sided pallet P2 can be easily and smoothly mounted onto the bottom plate, and the installation space for both pallets P1 and P2 can be effectively utilized by bringing the pallets P1 and P2 as close together as possible.
