Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic lift for lifting and feeding raw rice in a container to a hopper or the like in the next step when forming or processing rice.

[0002]

2. Description of the Related Art In a conventional food container automatic lift, an empty container on a U-shaped receiver that descends along an upright guide is unloaded, and then the actual container is manually placed on the receiver (actually). Japanese Patent Application No. 3-92541).

Since the actual container has a heavy weight (about 20 kg), it takes a lot of force to lift it with both hands and place it on the above-mentioned receiving tool, and it is not suitable for the work of ladies and old people because of the heavy work, and the safety and work efficiency are improved. It is difficult to improve.

[0004]

According to the present invention, even a woman or an elderly person can supply a heavy real container to the above-mentioned automatic lift to improve the work efficiency, and the food raw material in the real container can be used as a hopper for the next step above. The purpose is to throw in.

[0005]

In order to achieve the above object, the present invention provides an upright guide guide having an upper end portion curved forward on a machine stand, elevating and lowering along the guide, and A reciprocating rotary conveyor, which supports the U-shaped receiver so that it can be inverted at the upper end, is installed along the guide. The food container automatic lift upright guide which is supported by the force of an elastic body around the inside of the machine base and is provided with an entrance guide guide for the container cart and a longitudinal positioning stopper that can be opened and closed. The food container according to the first or the second invention, wherein the food container automatic lift container truck according to the invention is provided with limit switches for lowering the descent, and the container four corner positioning pieces are provided at the four corners of the upper surface of the cart. Constituted by the dynamic lift.

[0006]

In the present invention, the projections 12 ', 12', 12 'at the four corners of the rectangular real container 12 are provided on the inner surfaces of the positioning pieces 14, 14, 14, 14 at the four corners of the upper surface of the container truck 9.
12 'is placed, the lower end of the upper container 12 is fitted into the lower container 12, and the projections 12', 12 ', 12', 12 'of the upper container 12 are placed on the lower container 12 It is supported at the four corners of the outer peripheral flanges 5 and 5'and stacked in several stages (six stages in FIG. 2 ).

By pushing the dolly 9 and pushing it to the inner stoppers 16 and 16 between the guide guides 10 and 10 on the inside of the machine base 1 to perform lateral positioning, the longitudinal positioning stopper 11 is erected and closed. Is positioned.

In this state, the U-shaped receiver 3 descends from above, operates the limit switch 13 provided in the middle of the upright guide 2 to open the circuit, and stops the reciprocating rotary conveyor 4. Since 3 stops right above the uppermost container 12 stacked on the trolley 9, pull out the empty container 12 supporting both side flanges 5 and 5 on the lower surface non-return catches 6 and 6 of the receiving tool 3 and pull it out. After removing the switch, turn on the switch (not shown) on the control panel to open the U-shaped receiver 3.
6 From the solid line position to the imaginary line position in the figure, both side flanges 5 and 5 of the uppermost container 12 are arranged on the upper surfaces of the lower surface check supports 6 and 6 by the force of the elastic bodies 8 and 8.

In this state, the inverted L-shaped limit switch 17 provided at the central portion of the front end of the U-shaped receiver 3 is closed, and the conditions for raising the receiver 3 are aligned, and a switch (not shown) on the control panel is manually closed. By doing so, the receiver 3 rises along with the actual container 12 and the receiver 3 and the container 12 are turned upside down at the upper end portion 2'of the upright guide 2, so that the contents of the container 12 are in the next process. It is automatically put into the hopper 15.

In this state, the limit switch 18 on the upper end 2'is operated to rotate the reciprocating rotary conveyor 4 in the reverse direction so that the receiving member 3
And return the empty container 12 to the original horizontal state,
Further, it descends along the guide guide 2 and operates the descending stop limit switch 13 to open it, stop the receiver 3 and the empty container 12 at that position, and pull the empty container 12 forward by human power. Removal The above operation is repeated.

The actual containers 12 thus stacked on the trolley 9 are sequentially lifted from the upper stage to the lowermost stage, and food is put in or supplied to the upper next process hopper 15 to eliminate the container 12 on the trolley 9. The positioning stopper 11 is opened, and the carriage 9 is pulled out to the floor surface 19 in the front.
