In this carton attachment 43, as shown in FIG. 4, the carton attachment 43 is approached at an angle θ to a multi-stage, multi-row carton 2a mounted in a container (or in a freight vehicle). Out of a plurality of vacuum pads 54, one or two vacuum pads 54 on one side.
Is pressed against the carton 2a and compressed or elastically deformed to bring the contact plate 55 into contact with the carton 2a.
, The vacuum pad 54, the mounting plate 51, and the shaft 52 are swung about the spherical bush 53 against the spring 50a, and all the vacuum pads 54 are brought into close contact with the side surfaces of the carton 2a (see the dashed line in FIG. 4). . At this time, a carton 2a is adsorbed by connecting a vacuum generator (not shown) and all the vacuum pads 54 to each other.

Next, the snap cylinder 44 is operated in the contracting direction, and the arm 45, the carton attachment 43 and the carton 2a are swung clockwise about the pivot point of the arm 45, so that the bottom of one side of the carton 2a is moved. Then, the take-out arm moving cylinder 41 is operated in the contracting direction to take out the take-out arm 39 and take out the arm support plate 32.
(Linear guide set 38), the carton 2a is taken out, the suction by the vacuum pad 54 is released, and the carton 2a is taken out to the take-out conveyor 14 shown in FIGS. The carton 2a has various sizes, large and small.
Two or more pieces can be taken out at the same time.

In the carton attachment 43, the intermediate mounting plate 48 is mounted on the attachment mounting frame 47 so as to be able to move forward and backward by a predetermined stroke, and a spring 50b is provided between the intermediate mounting plate 48 and the attachment mounting frame 47. When the abutment plate 55 comes into contact with the carton 2a, the portion from the intermediate mounting plate 48 to the abutment plate 55 is retracted against the spring 50b to prevent the carton 2a from being damaged.

The take-out conveyor 14 shown in FIGS. 1 and 3
Is installed on the trolley 11 adjacent to the support 13.
The take-out conveyor 14 can be adjusted to an arbitrary height position on the tip side with the conveyor drive roller 60 as a fulcrum by operating the motor cylinder 61 in the expansion and contraction direction. 1 is a pair of side conveyors disposed on the left and right sides on the upstream side of the take-out conveyor 14 in the conveying direction, and these side conveyors 62 are a plurality of rows of conveyors 63.
When the cartons 2a on both the left and right sides are taken out of the cartons 2a mounted in the multi-stage and multi-row, the cartons 2a are taken out and conveyed to the conveyor 14. 1 and 3 is the cab 15.
Is operated by one operator 66 operating the operation panel 65 while checking the front and rear.

Next, the details of the bag attachment 68 will be described with reference to FIGS. 6 to 8 show an example of the bag attachment 68, and FIG. 9 shows another example of the bag attachment 68. One example of the bag attachment 68 will be described with reference to FIGS. 6 to 8. The bag attachment 68 is detachably fixed to the tip of the arm 45 by bolts (or pins) 46.
9, a claw mounting plate 72a, a claw 70, and a protection plate 71.

In this bag attachment 68, the snap cylinder 44 is operated in the contracting direction, and the arm 45, the attachment mounting frame 69, the pawl mounting plate 72a, and the pawl 70 are pivoted clockwise about the pivot point of the arm 45. In the state
The take-out arm 39 is advanced toward the bag 2b to a predetermined position, and then the snap cylinder 44 is operated in the extension direction to swing each of the above portions counterclockwise about the pivot point of the arm 45, thereby causing the claw 70 to move. It is inserted into one of the multi-stage, multi-row bags 2b mounted in the container (or in the freight vehicle). At this time, in order to prevent the bag from tearing,
And to insert the nail 70 into the bag 2b to a certain depth,
A protection plate 71 is provided.

Next, the take-out arm 39 is retracted, and the bag 2b is taken out and taken out onto the conveyor 14. On the other hand, the snap cylinder 44 is operated in the contracting direction, and the arm 45, the attachment mounting frame 69, the pawl mounting plate 72a, and the pawl 70 are swung clockwise about the pivot point of the arm 45, so that the pawl is moved. 70 is pulled out of the bag 2b. The nail 70
Usually, about 2 to 6 pieces may be sufficient, but the number may be increased or decreased depending on the strength of the bag.

Next, another example of the bag attachment 68 is shown in FIG.
This will be described below. In this embodiment, the claw mounting plate 72b is bent in a mountain shape along the outer shape of the bag 2b, and a plurality of claws 73 are attached thereto. The position of the take-out arm 39 is shifted with respect to the bag 2b to be taken. Also, it is possible to smoothly insert the claws 73 into the bag 2b. Next, the operation of the cargo carrying out equipment shown in FIGS. 1 to 8 will be specifically described. When taking out cartons (cargo) 2a mounted in multiple stages and multiple rows in a container (or in a freight vehicle), a carton attachment is taken out. The operator 43 seated in the driver's cab 15 operates the operation panel 65 to move the arm 45 to which the carton attachment 43 is attached, and to move the arm 45 up and down. Multi-stage mounted in a container (or in a freight vehicle) by turning in the left-right direction and swinging in the vertical direction, driving the take-out conveyor 14 attached to the trolley 11, and moving the trolley 11 back and forth as necessary. The multi-row cartons 2a are sequentially taken out rearward.

When taking out the baggage (cargo) 2b mounted in multiple stages and multiple rows in the container (or in the freight vehicle), the bag attachment 68 is removably attached to the arm 45, and then the operator's cab 15 An operator 66 seated on the vehicle operates the operation panel 65 to move the arm 45, to which the bag attachment 68 is attached, forward and backward, swing left and right, swing up and down, and take out the car attached to the cart 11. The driving of the conveyor 14 and the forward / backward movement of the trolley 11 are performed as necessary, and the multi-stage, multi-row bags 2b mounted in the container (or in the freight vehicle) are sequentially taken out rearward.

[0026]

As described above, when taking out cartons (cargo) loaded in multiple stages and multiple rows in a container (or in a freight vehicle) as described above, the carton attachment can be detachably attached to the arm. One operator, who is seated in the driver's cab, then operates the operation panel to raise and lower the arm with the carton attachment, move forward and backward, swing left and right, swing up and down, and a bogie. The removal of the cartons is performed one after another by driving the take-out conveyor attached to the car and moving the cart forward and backward as necessary. Also, when taking out bags (cargo) loaded in multiple stages and rows in a container (or in a freight vehicle), a bag attachment is detachably attached to the arm, and then one person sitting in the driver's cab, as described above. Operator operates the operation panel to move the arm with the bag attachment forward and backward, swing left and right, swing up and down, drive the take-out conveyor attached to the cart, and move the cart forward and backward. And then take out the bags one after the other in a carton,
This has the effect of mechanizing and labor-saving the work of unloading bags from containers or cargo vehicles.
