Description

[Detailed Description of the Invention] The present invention allows the transport vehicle introduced into the device to always take an accurate fixed position by positioning it front, rear, left and right, then secures the transport vehicle with parallel links and moves the transport vehicle using a drive mechanism. Pull it up to a position where it can be stacked in two layers,
A second transport vehicle is introduced directly below, and the lifted transport vehicle is lowered onto the second transport vehicle, stacked in two tiers, and then sent out of the equipment, ensuring reliable operation and easy work. This invention relates to a double stacking device for transport vehicles that doubles the storage capacity of transport vehicles.

Bags with casters, which are transport vehicles with storage bags stretched over a frame with wheels, are used in various workplaces, especially post offices.
Bags with casters are often used to store letters, parcels, etc., and are transported by truck.However, conventional bags with casters are rarely stacked and transported by truck, Because it is placed flat on a packing box and takes up a large space, it is uneconomical to transport it by truck.
In addition, stacking bags with casters in two tiers at input has the drawback of requiring harsh labor for the worker, but the structure is simple and convenient to handle, increasing the storage capacity on the cargo box of a freight vehicle. The development of a double stacking device for transport vehicles was universally sought after in the industry.

The present invention answers that need.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Guide plates 3 for the wheels 16 of the transport vehicle A are arranged opposite to each other for left and right positioning inside the base of the gate-shaped frame 1, and are connected to the cylinder 4. A hook body 6 is used for front and rear positioning operated by the driven link 5.
are arranged at two places in the front and back on one side of the lower part of the frame 1 to constitute the positioning mechanism 2, and a chain 10 is fixed to each of the pair of stand frames 7 installed on the frame 1 to form a motor drive mechanism. The hook body 12 is wound around a pair of left and right sprockets 8 rotating at 9 to raise and lower the platform stile 7, and the platform stile 7 is equipped with a hook body 12 that is operated by a parallel link 11, and each parallel link 11 is connected to a driving link. It is connected to the cylinder 13 via 14, and the reference numeral 15 is the frame of the transport vehicle A;
16 is the wheel, 17 is the storage bag, 18 is the frame 15
It is a support leg that is used for riding.

Next, to explain the work situation of stacking the transport vehicle A in two stages using this device, the transport vehicle A is introduced into the gate-shaped frame 1, and the wheels 16 of the transport vehicle A are set on the left and right positions using the wheel guide plate 3. Then, the drive link 5 connected to the cylinder 4 is actuated to rotate the hook body 6 to regulate the front and back position of the transport vehicle A, so that the transport vehicle A is always kept at a predetermined position by the positioning mechanism 2. Transport vehicle A
and put it in the state shown in Figures 1 and 2.

At this time, the frame 7 has been lowered to the lower part of the frame 1, and then the cylinder 13 installed on the frame 7 operates the parallel link 11 to move the hook body 12 to the frame 15 of the carrier A. After pushing it downward and engaging it with the carrier A as shown in FIG. 3, the sprocket 8 is rotated by a drive mechanism 9 such as a motor, thereby winding up the chain 10, and the carrier A is engaged. The carrier A is hoisted to the position shown in FIG. 4 by raising the platform stile 7 while it remains stationary. Place it like this and frame 1
After introducing the second transport vehicle A' into the interior and positioning it in the same manner as above, the supporting legs 18 of the first transport vehicle A are engaged with the underframe 15 of the second transport vehicle A' as shown in FIG. Then, the double stacking work of the first transport vehicle A and the second transport vehicle A' is completed.

As described above, according to the present invention, the transport vehicle introduced into the frame is positioned in a fixed position by a positioning mechanism that always precisely controls the left and right, front and rear directions, and double stacking work is carried out reliably. In order to take out the two-tiered transport vehicles, the wheels of the lower transport vehicle are used to send them out as a pair from inside the device, which is easy to handle and has excellent workability. In addition, the transport vehicle can be stacked in two layers and stored three-dimensionally in the cargo box of a freight vehicle, doubling the carrying capacity. This is an excellent and advanced invention that will greatly benefit the industry.
