1 is a side view showing an embodiment of a handling apparatus to which the present invention is applied, FIG. 2 is a rear view of FIG. 1, FIG. 3 is a plan view of FIG. 1, and FIG. 4 is a schematic view showing a toggle clamp. FIG. 5 and FIG. 5 are schematic diagrams showing the entire handling apparatus, FIG. 6 is a block diagram showing a balancer, and FIG. 7 is a schematic diagram showing a container.

As shown in FIG. 5, the handling device 10 is used for holding a container 11, transferring it to a pallet 12, and loading it at a distribution center or the like. At this time, the container 11 accommodates various goods that have been bided and is conveyed by the conveyor 13 to a place where the pallet 12 is stowed, and has a form as shown in FIG. In addition, the container 11 is a foldable type,
After discharging the articles, they are forwarded in a folded state.

When loading the container 11 on the pallet 12, the handling device 10 grips the container 11 with the container gripping device 10A and holds the container 11 with the weight of the container 11 held by the balancer 10B.
Can be transferred.

The balancer 10B is, as shown in FIG.
A torque motor 17 on a base 16 supported by the support pole 15, a first arm 18 rotatably supported by the base 16 and movable up and down by rotation of the torque motor 17;
Second arm 19 pivotally supported by first arm 18
And an operation box 21 rotatably supported by the second arm 19. The operation box 21 includes an operation lever 22.

FIG. 6 shows the balancer 10B.
When an upward or downward force is applied to the operation lever 22 as shown in (1), an electric signal proportional to the force applied by the command device 23 is generated. The position control circuit 24 includes the command device 23
And the outputs of the speed detection circuit 26 and the position detection circuit 27 connected to the tachogenerator 25 provided in the rotation system of the torque motor 17, and output a voltage proportional to the output of the command device 23. And the operation box 21 is operated by the torque motor 17 to operate the operation lever 2.
2 is raised or lowered in the same direction as the operation direction. As a result, the balancer 10B carries the weight of the container 11 supported via the container gripping device 10A below the operation box 21 by the output of the torque motor 17, and gives the operator a desired movement direction of the container 11 by the operation lever 22. , The container 11 can be moved.

On the other hand, the container holding device 10A is shown in FIGS.
As shown in FIG. 4, a horizontal member 30 connected to the lower portion of the operation box 21 provided in the balancer 10B, left and right outer contact plates 31 contacting the outer surface of the side plate 11A of the container 11, and contacting the inner surface of the side plate 11A. Left and right inner backing plates 32,
Locking recesses 1 provided on the left and right sides of the outer surface of the side plate 11A
A locking rod 33 capable of locking to the locking recess 1B is provided with left and right toggle clamps 34 for engaging and disengaging the locking recess 11B. The clamp arms 35 of the right and left toggle clamps 34 are connected by a single operation lever 36.

Here, the left and right outer patch plates 31 and the inner patch plate 32 are fixed to both left and right ends of the horizontal member 30, respectively.

As shown in FIG. 4, each of the toggle clamps 34 is disposed on left and right support brackets 37 fixed to the left and right outer backing plates 31, and rotatably supports the clamp arm 35 on the support shaft 38. The clamp arm 35 has an elongated hole 35A. On the other hand, one end of the link 102 is pin-connected to a support shaft 101 provided on the support bracket 37, and the locking rod 33 is supported by a cylindrical guide 39 provided on the support bracket 37 so as to be linearly movable.
3, one end of the link 41 is connected to the link 41, and the connecting pin 103 for connecting the other end of the link 41 to the other end of the link 102 is engaged with the elongated hole 35A of the clamp arm 35. It was done. Thus, in the toggle clamp 34, when the clamp arm 35 is rotated from the unclamped position in FIG. 4B to the clamped position in FIG. 4A, the link 41 coincides with the axis of the locking rod 33. Become independent after the dead point and maintain the clamped state.

In the container holding device 10A,
When the outer patch plate 31 and the inner patch plate 32 are set on the side plate 11A of the container 11, the left and right inner patch plates 32 are set at the left and right inner corners of the container 11, and the outer patch plate 31 and the inner patch plate 32 Between the container gripper 10A and the container 11 and, as a result, the locking rods 33 of the left and right toggle clamps 34. Are configured to be automatically able to correspond to the locking recesses 11 </ b> B of the container 11.

The container holding device 10A further includes a bottom pressing bar 43 that contacts the bottom outer surface of the side plate 11A of the container 11. Bottom holding bar 43
Is an inverted T-shaped support member 4 suspended at the center of the horizontal member 30.
4 via bolts 45 and nuts 46, and the side plate 1
The contact position with respect to 1A can be adjusted back and forth.

Next, a procedure for using the handling device 10 will be described.

(1) Operation lever 36 of toggle clamp 34
And the clamp arm 35 is set to the unclamping position,
By manually operating the operation lever 22 of the balancer 10B, the outer contact plate 31 and the inner contact plate 32 of the container gripping device 10A are operated.
Is set on the side plate 11A of the container 11. At this time,
The locking rod 33 of the toggle clamp 34 is automatically positioned corresponding to the locking recess 11B of the container 11 as described above.

(2) Operation lever 36 of toggle clamp 34
Then, the clamp arm 35 is set to the clamp position, and the locking rod 33 is engaged with the locking concave portion 11B of the container 11. Thus, the container gripping device 10A completes gripping the container 11.

(3) By manually operating the operation lever 22 of the balancer 10B, the container 11 gripped by the container gripping device 10A is moved in desired vertical and horizontal directions.

(4) After the container 11 is moved, the operation lever 36 and the clamp arm 35 of the toggle clamp 34 are set to the unclamping position again, and the locking rod 33 is disengaged from the locking recess 11B of the container 11. This allows
The container holding device 10A releases the container 11 and the transfer is completed.

Next, the operation of the above embodiment will be described.

In the above embodiment, since the toggle clamp 34 is used as the holding means for the container 11, the following operations are provided.

The operation of the clamp 34 does not require a pneumatic circuit or an electric circuit.

As described above, the configuration is simplified while the configuration is simplified.
The tener 11 can be easily and firmly gripped.
Since there is no need to accompany the pneumatic piping, electric wiring, and the like attached to the clamp 34 when transferring 1, the light workability of the handling device 10 is ensured, and emergency recovery in the event of a trouble is also easy.
