Next, the operation method and operation of the container fixing device 100 configured as described above will be described in order.

(1) Cone retracted state (FIGS. 3, 4 and 5) The bulging portion 13a of the handle 13 is locked on the lower surface of the peripheral edge of the central opening 11a of the central plate 11, and the cone 1
And the collar 2 are stored inside the cylindrical housing 4. The longitudinal direction of the cone head 1b in plan view and the longitudinal direction of the collar body 15 in plan view are 9 as shown in FIG.
It is in a state shifted by 0 °. Also, the collar side stopper 1
As shown in FIG. 5, the positional relationship between the cone 6 and the cone-side stopper portion 14 is such that the cone-side stopper portion 14 is adjacent to the collar-side stopper portion 16 in a counterclockwise direction, as shown in FIG.

(2) Cone Protruding State (FIGS. 6, 7, and 8) The grip 13b of the handle 13 is grasped from the cone retracted state, and the handle 13 is rotated 90 ° in a counterclockwise direction in plan view. The rotation of the handle 13 causes the handle 13
Bulge 13a and central opening 11a of central plate 11
Is released, and the handle 13 can be raised by the urging force (elastic return force) of the pressing spring 3. In addition, the longitudinal direction of the cone head 1b coincides with the longitudinal direction of the collar body 15, so that the cone 1 and the collar 2 can protrude from the loading platform 201 through the central opening 6b of the top plate 6. When the cone can be projected, the positional relationship between the collar-side stopper 16 and the cone-side stopper 14 is as follows.
In a plan view, as shown in FIG.
Are in a positional relationship adjacent to the collar side stopper portion 16 in the clockwise direction.

(3) Cone Protruding State (FIG. 9) The handle 13 is operated to lift the cone 1 and the collar 2 from the above-mentioned cone protruding state. During this operation, since the urging force of the pressing spring 3 is applied, the cone 1 and the collar 2
The operation force for lifting the slab is small. And cone 1
And the collar 2 passes through the central opening 6b of the top plate 6 and the loading platform 20.
1 to protrude. At this time, the collar 2 and the cone 1 rise vertically because the notch 7b of the rotary plate 7 is engaged with the vertical guide rail 5. Then, the cone 1 and the collar 2 are lifted until the protruding portion 7a of the rotating plate portion 7 contacts the lower surface of the top plate 6.

(4) Container Acceptable State (FIG. 10, FIG. 1)
1, FIG. 12) The handle 13 is turned 45 ° counterclockwise in plan view from the above-mentioned cone protruding state. At the start of the rotation, as described above, since the cone-side stopper portion 14 is adjacent to the collar-side stopper portion 16 in the clockwise direction, the handle 13
Is rotated by 45 ° as described above, the cone-side stopper portion 14 and the collar-side stopper portion 16 are simultaneously rotated 45 ° counterclockwise. For this reason, the cone 1 and the collar 2 simultaneously rotate counterclockwise by 45 °, and the protruding portion 7 a of the rotating plate portion 7 comes to rest on the upper surface 5 a of the vertical guide rail 5.

(5) Container fixed state (FIGS. 13, 14,
(Fig. 15) When the container fixing device 100 is ready to receive the container, the container 300 is lowered from above and set on the loading platform 201 so that the cone 1 is inserted into the fixing hole 301. Thereafter, the handle 13 is rotated clockwise by 90 ° in a plan view. By this operation, only the cone 1 rotates, the lower surface of the cone 1 covers a part of the periphery of the fixing hole 301, the periphery of the fixing hole 301 is locked by the container fixing device 100, and the container 300 is It is fixed to 201.

By the above operations and operations, the container fixing device 100 shifts from the cone storage state to the container fixing state, and the container 300 is fixed to the loading platform 201. On the other hand, when the container fixing device 100 is moved from the container fixing state to the cone storing state in order to remove the container 300 fixed to the loading platform 201 from the loading platform 201, the operation and operation reverse to the above-described operations and operations are performed.

According to the container fixing device 100 according to the first embodiment as described above, since the cone 1 and the rotating plate 7 are separate and separated, the container receiving state is changed from the container receiving state to the container fixing state. The operation force for rotating only the cone 1 at the time of moving to is sufficient, so that the burden on the operator can be reduced.

FIGS. 16 and 17 show the configuration of the container fixing device 100 according to the second embodiment. The container fixing device 100 according to the second embodiment is a “springless” type container fixing device 1 having no pressing spring 3.
00.

Here, FIG. 16 is a longitudinal sectional view of the container fixing device 100 in the cone storage state, and FIG. 17 is a longitudinal sectional view of the container fixing device 100 in the container fixed state.

"Springless" type container fixing device 1
Reference numeral 00 denotes a configuration in which the rotating plate portion 7 is supported by the annular lid 9 located at the lower end of the cylindrical housing 4 when the cone is stored. Further, the length of the handle 13 in the height direction is set short. Other configurations are the same as those of the above-mentioned “with spring” type container fixing device 100.
