Abstract

PROBLEM TO BE SOLVED: To eliminate load holding work by moving a takeout device forward to hold a load and backward to take out the load onto a conveying table, and conveying the taken-out load by a conveying device. SOLUTION: A travel device 2 is moved to travel until a takeout device 8 comes into a load taking position. An elevating device 3 is moved in such a way as to be adjusted to a load 10 in an uppermost stage of a face where the takeout device 8 takes the load. At this time, a workbench 5 is elevated into a position where a worker can work easily. When a suction pad 8f is brought into contact with the side face of the load 10 and a switching valve 8g is operated to suck air from the pad 8f, the load 10 is sucked to the pad 8f to close an air suction port. In addition, a vacuum device 9 sucks air in a bellows hose 8e in order to suck the air, and the bellows hose 8e is contracted. The force of pulling out the load 10 is thereby generated. and the load 10 can be placed on a table 8a without needing the force of the worker. The load 10 conveyed onto a conveying table 4 is conveyed to a conveying device 6.

The traveling device 2 is provided with an elevating device 3 having a height slightly lower than the height of the door opening of the cargo chamber 1, and the elevating device 3 is provided in front of the elevating device 3. The left and right transport tables 4 and the work table 5 in the front-rear direction, which are raised and lowered independently of each other, are provided in the section, and a transport device 6 is provided at the rear of the lifting device 3.

Further, at the front end of the transfer table 4, the cargo room 1
Is provided with a slide rail 7 that is slightly shorter than the door opening width, and a take-out device 8 that takes out the load 10 in the cargo room 1 through the slide rail 7 is provided. The take-out device 8 slides on the slide rail 7. A slide table 8a, a carriage 8b that moves back and forth on a roller conveyor of the slide table 8a, and a swing arm 8 whose one end is pivotally supported on the carriage 8b.
c, the lower end of the front end is pivotally supported by the other end of the swing arm 8c, and the rear end is linked to a bracket 8d provided at the rear end of the slide table 8a and attached to the bellows hose 8e and the tip of the bellows hose 8e. Suction pad 8f and switching valve 8g provided on the side of the bellows hose 8e and the bellows hose 8
The bellows hose 8e is formed of a pushing spring 8h provided between the e and the vacuum bellows 8e and is connected to a vacuum device 9 provided in the traveling device 2 via a hose 11.

When the load 10 is a bag as shown in FIG. 4, a hook 8i is provided at the tip of the bellows hose 8e instead of the suction pad 8f so that the load 10 can be pulled and pulled out. Next, the operation flow of unloading will be described with reference to FIGS. 2, 3 and 5. (1) The traveling device 2 is moved and moved until the unloading device 8 reaches the unloading position. (2) The lifting device 3 is moved so that the unloading device 8 fits the uppermost load 10 on the surface on which the unloading is performed. At this time, the workbench 5 is moved up and down to a position where the worker can easily work. (3) When the suction pad 8f is applied to the side surface of the load 10 and the switching valve 8g is operated to suck air from the pad 8f, the load 10
Is adsorbed by the pad 8f and the air inlet is closed. Further, since the vacuum device 9 tries to suck in air, the air in the bellows hose 8e is sucked in and the bellows hose 8e contracts, thereby generating a force for pulling out the load 10, so that the operator can load the load 10 onto the table 8a.
