Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle commonly used for transporting dry and wet objects such as oil-coiled and oilless coils. . 2. Description of the Related Art FIG. 3 is an explanatory view of a conventional automatic guided vehicle commonly used for transporting dry and wet objects such as a coil with oil and a coil without oil. In the figure, since the automatic guided vehicle carries heavy objects such as the coil 10, only one saddle 11 is provided at the center of the vehicle so that an unbalanced load is not applied to the vehicle. A lifter 1 that moves the coil 10 up and down for the vehicle 10 to change the coil 10
2. Equipped with a lift cylinder 13 and the like. [0003] In the conventional automatic guided vehicle as described above, a finished oil-coated coil in which the rust-preventive oil is applied to the coil 10 and an oil-coated coil due to a later processing step. There are two types of oilless coils that must never be attached. When these two types of coils 10 are transported by a common automatic guided vehicle, two types of coils are mounted on the center saddle 11 in a conventional automatic guided vehicle. Because coil 10 must be mounted,
There is a problem that the oil of the oiled coil adheres to the oilless coil. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and a vehicle is commonly used for transporting a plurality of different types of goods, and one type of goods is provided at the center of the vehicle. in the transport vehicle for transporting and mounted, located in center of the vehicle

It is characterized by being constituted as follows. That is, in the transporting vehicle according to the present invention, a plurality of transporting vehicles which are shared for transporting a plurality of different types of transported products and which carry one type of transported product in the center of the vehicle and respectively correspond to the plurality of types of transported products. saddle, slide on the vehicle is provided to be positioned in the center of the vehicle, each of a plurality of types of transport was by exchanging slide the saddle, slide the
On a dedicated saddle elevated by the position and the lifter to the center of the vehicle by de, it can be transported and installed. FIG. 1 and FIG. 2 are explanatory views of an automatic guided vehicle according to an embodiment of the present invention. In the figure,
The automatic guided vehicle according to the present embodiment is commonly used for transporting a dry object and a wet object such as a coil with oil and a coil without oil, and as shown in FIG. For carrying, only one saddle 4 is arranged at the center of the vehicle 1 so that an unbalanced load is not applied to the vehicle 1. The vehicle 1 is equipped with a lifter 5, a lift cylinder 6, and the like for moving the coil 10 up and down for the work of replacing the coil 10. The automatic guided vehicle is provided with an automatic saddle changing device such as a slide cylinder 2 as shown in FIG. 1 and lifters a saddle 4a for a coil with oil and a saddle 4b for a coil without oil. 5 so that it can be automatically switched by sliding upward. The slide guides 8a and 8b for guiding the saddles 4a and 4b are fixed to the upper part of the vehicle 1 in the longitudinal direction of the vehicle 1.
The saddle guide 3 is slidably held by the slide guides 8a and 8b. The saddle guide 3 is movably connected to the vehicle 1 by a slide cylinder 2. The slide guides 7a and 7b of the saddles 4a and 4b are fixed to the upper part of the vehicle 1 so that when the lifter 5 is at the lower end, the upper surface and side surfaces thereof are aligned. Saddle 4a,
4b is a slide guide 7a, lifter 5,
It is slidably mounted on the saddle slide guide 7b. The saddles 4a and 4b are held in a square hole of the saddle guide 3 so as to be vertically movable. When the saddle guide 3 slides by the slide cylinder 2, the saddle guide 3 pulls the saddles 4a and 4b to slide. The lifter 5 is fixed to a rod of a lift cylinder 6, and moves up and down by the lift cylinder 6 fixed to the vehicle 1. The upper surfaces of the saddles 4a, 4b are formed in a V-shaped concave shape so that the coil 10 is stably supported. The horizontal cross section of the lifter 5 is saddles 4a, 4
b is smaller than the horizontal section and saddles 4a, 4b
In the lower part, a fitting hole with the upper part of the lifter 5 is formed so that the upper part of the lifter 5 can be fitted to the lower parts of the saddles 4a and 4b. FIG. 1E shows a state in which the lift cylinder 6 is lowered to lower the lifter 5 to the lowest position. At this time, the slide of the saddle 4 installed on the upper surface of the lifter 5 and the upper part of the vehicle 1 is performed. The upper surfaces of the guides 7a and 7b coincide with each other. The saddles 4a, 4b are inserted into two square holes of the saddle guide 3, and the shape of the square holes and the saddles 4a, 4b
The shape of b is substantially the same. The arrangement relationship of the lifter 5, the saddle guide 3, the square hole of the saddle guide 3, the slide cylinder 2, and the like is such that when the slide cylinder 2 expands and contracts, one of the square holes of the saddle guide 3 is located directly above the lifter 5. The upper surface of the lifter 5 can be fitted into the fitting holes below the saddles 4a and 4b. As shown in FIG. 1, when the slide cylinder 2 is extended, the saddle guide 3 slides to the left in the figure, and the saddle 4a for the coil with oil slides on the lifter 5 located at the center of the vehicle 1. Be placed. When the lift cylinder 6 is lifted in this state, the lift 5 is lifted with the saddle 4a placed thereon. A coil with oil is placed on the saddle 4a and transported. When the slide cylinder 2 is contracted as shown in FIG. 2, the saddle guide 3 slides rightward in the figure to lift the lifter 5 located at the center of the vehicle 1.
A saddle 4b for an oilless coil is slid and disposed on the upper side. When the lift cylinder 6 is lifted in this state, the lifter 5 is lifted with the saddle 4b placed thereon. The oilless coil is placed on the saddle 4b and transported. In any case, the coil 10 is mounted on the center of the vehicle 1 and transported. In conventional automatic guided vehicles, there are two types of coils: a finished oil-coated coil in which rust-preventive oil is applied to the coil, and an oil-free coil to which oil must never be attached because of a later processing step. If these two types of coils are transported by a common automatic guided vehicle, the conventional automatic guided vehicle must mount two types of coils on the center saddle, so the oil in the oiled coil is Although there is a problem of sticking to the coil having no oil, in the automatic guided vehicle, a saddle 4a dedicated to the coil with oil and a saddle 4b dedicated to the coil without oil are provided, and the slide guides 7a and 7b of the saddle 4 and the lifter 5 are provided.
Are arranged in a straight line so that the saddles 4a and 4b can mesh with each other and slide on the saddles 4a and 4b.
a, 4b are held by a saddle guide 3 having a square hole capable of moving up and down, and the saddle guide 3 is slidably connected to the vehicle 1 by a hydraulic slide cylinder 2.
The center of the vehicle so that oil does not adhere to the oilless coil via the saddle 4 even when both coils 10 with and without oil are transported by one automatic guided vehicle, and that the vehicle is not subjected to an uneven load. The lifter 6 can be used to carry the coil 10 by using the lifter 6, and the oil-less coil and the oil-added coil can be respectively used for the reloading work of the coil 10.
Since it can be mounted and transported on the a and 4b, the oil of the oiled coil does not adhere to the oilless coil via the saddle 4. The transport vehicle according to the present invention is configured as described above, and can transport a plurality of types of transported articles mounted on dedicated saddles located at the center of the vehicle. Therefore, for example, the oil of a certain conveyed article does not adhere to another conveyed article via the saddle.
