【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. First, a transport vehicle 11 (see FIGS. 1 and 2) having a conveyor (transported material loading device) 17 will be described. The transport vehicle 11 is a forklift type self-propelled vehicle. The transport vehicle 11 is an unmanned transport vehicle that travels on a designated course on the floor by means of traveling wheels 12, 12, 12 and drive wheels 13.

The transport vehicle 11 has a fork (elevating body) 14. The fork 14 is formed in an L shape with a pair of horizontal portions 15 and 15 and a vertical portion 16. The horizontal portion 15 is a long plate-shaped member formed in the horizontal direction. A conveyor 17 is provided on the pair of horizontal portions 15 and 15 via a floating device 10. The vertical portion 16 is a portion that moves up and down along a support column 19 of the vehicle body by the guide of known linear motion bearings 18, 18. The fork 14 is connected to a hydraulic cylinder 21 by a chain 20 and can be moved up and down to the floor F by the hydraulic cylinder 21.

The conveyor 17 (see FIG. 1) is composed of a plurality of rollers 22. Each roller 22 is rotated by a motor 37 (see FIG. 1) via a belt (not shown). On both sides of the conveyor 17, conveyance object guides 23, 23 for guiding the transferred conveyance object W are provided. At the end of the conveyed product guide 23, a conveyed product receiving piece 24 that is inclined in the horizontal direction and away from the conveyor 17 is formed. That is, at the end portions of the pair of conveyed object guides 23, conveyed object receiving pieces 24, 24 that are open to each other in a C-shape are formed.

Next, the floating device 10 will be described. The floating device 10 is a device for absorbing the deviation when the transport vehicle 11 is stopped by being displaced with respect to the transfer conveyor 40 (see FIG. 1) so that the transfer of the article W is performed. is there.

The floating device 10 includes a frame 30, four known linear motion bearings 31, four springs 32, two lock mechanisms 33, and the like. The frame 30 is a member that supports the entire floating device 10 on the fork 14. The linear motion bearing 31 movably supports the conveyor 17 on the frame 30 in the longitudinal direction of the roller 22 of the conveyor 17 (the direction of arrow B in FIGS. 1 and 3) and the four corners of the conveyor 17 and the frame 30. It is provided between and.

Four springs 32 are provided between both sides of the conveyor 17 and the frame 30. The four springs 32 have a function of pulling the conveyor 17 from both sides and returning it to a predetermined position at all times.

The lock mechanism 33 (see FIG. 3) is a mechanism that locks the conveyor 17 to the frame 30, and is provided at two locations (see FIG. 1). The lock mechanism 33 (see FIG. 3) is composed of a cylinder 35 provided on the frame 30 and protruding from the pin 34, and an engaged hole 36 provided on the bottom surface of the conveyor 17 to receive the pin 34. In addition, the lock mechanism may be a mechanism that locks the conveyor to the frame by sandwiching the conveyor with a pair of turning arms (not shown).

Next, an operation of transferring the transferred article W from the transferred article transfer location to the transfer vehicle 11 will be described. It is assumed that the transport vehicle 11 is deviated from the place where the transported article W is transferred and stopped. First, the transport vehicle 11 raises and lowers the fork 14 to align the height of the conveyor 17 with the height of the transfer conveyor 40 installed at the transfer location of the transported object. If the transfer conveyor 40 is installed at a relatively low position near the floor F, the fork 14 is lowered to near the floor F, and the height of the conveyor 17 is aligned with the height of the transfer conveyor 40. .

Next, the pin 34 of the lock mechanism 33 is pulled out from the engaged hole 36 so that the conveyor 17 can be freely moved in the arrow B direction. The transported article W is sent from the transfer conveyor 40 to the conveyor 17 on the transport vehicle 11. At this time, since the transport vehicle 11 is stopped at the displaced position, the transported article W contacts the transported article receiving piece 24. However, the conveyed product W is sent as it is.

Therefore, the conveyed product W presses the conveyed product receiving piece 24 along the inclination. The conveyor 17 is guided by the linear motion bearing 31 and is allowed to escape on the fork 14 against the spring 32. As a result, the conveyed product W is smoothly fed onto the conveyor 17. Further, the conveyed article W slides on the surfaces of the conveyed article receiving piece 24 and the conveyed article guide 23, but since the conveyor 17 escapes and moves, the conveyed article guide 23 and the conveyed article W are worn more than before. Also few. Also, there is little dust generation.

After that, the conveyor 17 receives the entire conveyed article W and is returned to the original position by the spring 32. Finally, the pin 34 of the lock mechanism 33 enters the engaged hole 36, and the conveyor 17 is fixed on the transport vehicle 11. Therefore, even if the transport vehicle 11 deviates from the transport item transfer location and stops, the transport items W are loaded at a predetermined position on the transport vehicle 11, and thereafter, another transport item transport location. When unloaded, it is accurately unloaded into place.

By the way, the stopping accuracy of the carrier 11 is ± about 10 to 20 mm. Since the center deviation of the transported object is absorbed by the floating device 10 each time, the transport vehicle 11 can smoothly receive the transported object W each time.

[Effect of device]

 According to the carrier of the present invention, since the carrier loading device is supported by the ascending / descending body that can move up and down to the traveling surface of the carrier, it is possible to load the carrier placed near the traveling surface. Therefore, the transfer operation becomes safe and damage to the transported object is reduced. Further, the height region for receiving the conveyed objects can be widened by lowering the conveyed object loading device near the traveling surface.
