Description

[Detailed Description of the Invention] [Industrial field of application] The present invention can be used for transporting and handling two pallets with legs using a transport vehicle capable of raising and lowering a vehicle body.
The present invention relates to a carrier vehicle that can efficiently realize a variety of products, which are produced from a production line in small lots, in a storage area in an efficient and short-time manner, so that a journal can be stored efficiently.

[Conventional technology]

There is no example of means for transporting the two separately placed legged pallets shown in FIGS. 9 and 10, and the method shown in FIG. 11 can be considered as an easily conceivable method.

The pallet with leg 1-A, on which the object to be transported 1 is placed, is loaded on the rear part of the carrier carrier shown in FIG.
Move backward to the front of B, place the 1-A pallet on the floor in the immediate vicinity of the 1-B pallet, and the cargo bed moves backward as it enters the space 3 between the lower legs 2 of the two legged pallets. As shown in Fig. 4, place two pallets with legs on the platform and transport them to the specified position. At this time, the fact that the vehicle carrier bed invades the lower part of the pallet with legs means that the carrier platform is allowed to enter space 3 in FIG.

[Problems to be solved by the device]

As an alternative to this method, Fig. 11 shows a pallet with legs 1 at the rear of the loading platform.
-Load A, set it on the front floor of 1-B pallet,
The method of moving the carrier vehicle backward and loading both 1-A and 1-B pallets is shown. In the figure, 5 is a driver's seat and 7 is a luggage carrier. In the case of this alternative, depending on the structure of the rear part of the loading platform and the attachment situation of auxiliary equipment, it is necessary to secure X shown in FIG. 11 as a necessary space between the front and rear pallets in FIG. Only at this portion, the entire length of the vehicle body carrier becomes long, the turning radius of the vehicle body increases, and a large number of planes for transporting the pallet with legs are required. In addition, even in the yard, the plane of the X portion is used unnecessarily, and the yard efficiency becomes poor.

12 Although the figure shows a with legs palette ~ bed of relation during normal operation, taking into account the human power driving accuracy, with legs pallet Ashinai width W _1>
Determine the cargo bed width W. As shown in FIG. 12, the pallet with legs is usually set eccentrically to the bed. When alternative use, internally with legs palette, in the vehicle body does not interfere with the pallet leg, the allowable width is assumed W ₂ -W only without operation very difficult that can reverse intrusion. Also, in case of alternative plan, 1
-It takes time to move the loading platform up and down for the temporary placement of the 1-A pallet at the front of the B pallet, and a distance confirmation sensor is required to ensure the space X between the front and rear pallets with high accuracy.

However, according to the case of the present invention described later, since the 1-A pallet is already loaded on the loading platform, the allowable width between the 1-B pallet and the loading platform is W ₁ -W, and the body loading platform moves backward without interfering with the pallet. Because it can be done, it becomes very easy to reverse the vehicle body,
(W ₁ -W)> a (W ₂ -W).

[Means for Solving the Problems]

The present invention has solved the above-mentioned problems, and its gist is as follows.
Carrying two pallet-carrying pallets, equipped with a pallet-carrying pallet auxiliary lift device, which is characterized in that a pallet-carrying pallet auxiliary lift device is installed on the front loading platform of a vehicle capable of raising and lowering a vehicle body. It is a vehicle.

[Examples and functions]

The vehicle of the present invention will be described in detail with reference to the operation explanatory views of the embodiment apparatus shown in FIGS.

As shown in the figure, the vehicle of the present invention is equipped with an auxiliary lift device (lift state) 6 at the front of the loading platform, and the auxiliary lift device 6 is already loaded on it.
Set the A pallet to the lifted state.

1-B pallet is additionally loaded, so loading platform 7-1
Prevents the lower part of the 1-A pallet leg from coming into contact with the floor surface when the (lowered state) enters the 1-B pallet leg lower space 3 in the lowered state.

Below, loading pallets placed in different places, 1-A, 1-B
Carrying at the same time and bringing them in to the specified position or 1-A, 1-
The operation when the B loading pallet is sorted and carried into different places will be described with reference to the drawings. As shown in FIG. 1, first, the cargo bed with the auxiliary lift device 6-1 lifted down enters the lower part of the pallet with 1-A legs in the lowered state.

After that, place the 1-A pallet on the carrier as shown in FIG.
Traveling with the loading platform raised, and the next cargo pallet to be transported 1-
Drive to position B. FIG. 3 is a diagram in which the loading platform enters the second pallet 1-B. At this time, the loading platform is lifted down to allow the loading platform to enter the lower portion of the 1-B pallet, and an auxiliary lift device 6-2 is installed to prevent the lower leg of the pallet 1-A already placed in front of the loading platform from coming into contact with the floor surface. Raise to a state. Next, as shown in FIG. 4, the two 1-A, 1-B pallets are transported to the predetermined positions, and although not shown, the loading platform is lowered at the predetermined positions to make the two pallets the same. It is possible to transport the pallets to different locations, and when transporting each pallet to different positions, as shown in FIG.
-2 is raised to ensure that the lower part of the 1-A pallet does not come into contact with the floor surface, and only the 1-B pallet is transported to the specified position, and then the front part 1-A pallet is transported to another specified place. .

In this way, utilizing the function of the auxiliary lift device at the front of the loading platform,
You can freely transport two pallets with loading legs. As shown in FIG. 6, when carrying a long product such as 1-C, the auxiliary lift device can be set in the lowered state of 6-1 and carried by one pallet with legs.

An example of the structure of the auxiliary lift device is shown in Figs. The lift function may be any means such as a jack or hydraulic cylinder, but in the case of the present invention, a hydraulic ram is used as the same power source for lifting the platform. The pallet used in the present invention may have the same structure as the legged pallet used in the conventional method.

[Effect of device]

 The vehicle of the present invention has the following excellent functional effects.

1) It is possible to stock two pallets with legs while securing a necessary minimum space between pallets and securing a good storage efficiency.

2) Since the second pallet with legs is loaded, the work of invading the vehicle body under the pallet is only one pallet with legs ~
It suffices to drive while paying attention to the distance between the vehicle bodies, and the amount of the distance is large, so that the vehicle body intruding operation is easy.

3) As an alternative, load the pallet with legs on the rear of the vehicle, lower it once on the floor at the front of the 1-B pallet, and then lift the pallet with an auxiliary lift device in advance as compared with the operation of moving backward. In addition, since the reverse operation is possible, the operating time can be shortened.
