【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In this specification, "front and rear" means that the upper side of FIG. 4 is front and the opposite side is rear, with reference to FIG.
Left and right means the left and right sides in FIG. 4 as left and right.

As shown in FIG. 4, the palletizer is a robot for conveying the bottle B and the separate sheet C.
Have 11. The robot 11 has a bendable arm 12. At the tip of the arm 12, a suction member 13 capable of sucking both the bottle B and the separate sheet C is provided. In FIG. 4, the turning range of the arm 12 is shown by a chain line.

A separate sheet supply station S1 is provided behind the robot 11, and a bottle loading station S2 is provided obliquely to the right of the robot 11. A separate sheet sterilization station S3 is located diagonally to the right behind the robot 11.

From the front of the robot 11 to its left,
A bottle alignment device 21 is arranged. Also, robot 11
A pallet conveyor 22 having a transport path via the bottle loading station S2 is arranged on the right side of the.

Referring to FIG. 1, a large number of separate sheets C are stacked and placed in a magazine 23 on the floor of the separate sheet supply station S1. A pallet 24 is placed on the conveyor 22 of the bottle loading station S2. On this pallet 24, a single-stage bottle B is stacked, and a separate sheet C is placed on it.

A separate sheet temporary placing table 25 is arranged so as to straddle the end of the leftward path of the pallet conveyor 22 on the loading side. A square frame-shaped case 31 is provided on the table 25. A separate sheet receiving member 32 is arranged so as to cover the upper end opening of the case 31. The separate sheet receiving member 32 is composed of round bars assembled in a lattice shape. Above the separate sheet receiving member 32, L-shaped stoppers 33 are arranged at the front edge portion and the left edge portion thereof. Further, two frontward positioning cylinders 34 are arranged above the rear edge of the separate sheet receiving member 32, and two leftward positioning cylinders 35 are arranged above the right edge thereof. Below the separate sheet receiving member 32, a plurality of ultraviolet lamps 36 arranged in the front-rear direction inside the case 31 are arranged.

In the separate sheet supply station S1, the robot 11 sucks and lifts the uppermost separate sheet C, conveys it to the separate sheet sterilization station S3 as it is, and releases the suction there. Then, the separate sheet C transported to the sterilization station S3 is received by the receiving member 32. In this case, as shown by the alternate long and short dash line in FIG. 3, the separate sheet C is initially placed at a position distant from the stopper 33, but after a lapse of a predetermined time, the positioning cylinders 34, 35 are actuated, and the alternate long and two short dashed line in FIG. As shown by, the separate sheet C is displaced to a position where it comes into contact with the stopper 33, and thereby the positioning of the separate sheet C is achieved. While the separate sheet C is being received by the receiving member 32, the lower surface of the separate sheet C is sterilized by being irradiated with ultraviolet rays.
As described above, by shifting the separate sheet C, the portion of the receiving member 32 that was blocked from being irradiated with ultraviolet rays before being displaced is irradiated with ultraviolet rays after being displaced. The whole is sterilized.

The robot 11, which has released the suction of the separate sheet C at the sterilization station S3, turns the arm 12, sucks and lifts the bottle B from the bottle aligning device 21, and conveys it to the bottle loading station S2. The pallet 24 waiting at the bottle loading station S2 is loaded with the bottle B and the separate sheet C loaded in the previous cycle, and the bottle B is loaded on the separate sheet C. The bottle B, which has been conveyed in 4 to 5 times, is stacked on one separate sheet C. During this time, it takes about 3-4 minutes, which is
Sufficient time for sterilization.

When the required number of bottles B are stacked on the separate sheet C, the robot 11 moves to the sterilization station S.
The sterilized separate sheet C is adsorbed and lifted from 3 and conveyed to the bottle loading station S2, and the adsorption is released there, whereby the separate sheet C is placed on the loaded bottle B. Then, in order to adsorb the separate sheet C in the supply station S1 to be sterilized next, the arm 12 of the robot 11 turns to complete one cycle of stacking work.

5 and 6 show a modification of the above embodiment. A movable rail 41 extending in the left-right direction is arranged above the carry-in side leftward path of the pallet conveyor. The movable rail 41 is movably supported by a frame 42. As with the lower case 31, the upper case 44 accommodating the ultraviolet lamp 43 is suspended from the movable rail 41.

The upper surface of the separate sheet C is sterilized by moving the movable rail 41 in synchronism with the loading / unloading of the separate sheet C to / from the sterilization station S3.

7 and 8 show another embodiment. This embodiment is applied to a sweeper type palletizer.

On the left side of the separate sheet supply station S1, there is a bottle loading station S2, and on the right side thereof is a separate sheet sterilization station S3. A guide rail 51 is provided above these three stations S1 to S3, and a suction member 52 is arranged so as to move along the guide rail 51. Bottle loading station S
A lifter 53 for raising and lowering the pallet 24 so as to keep the stacking level constant is arranged at 2. A temporary holder 54 is arranged in the separate sheet sterilization station S3. The temporary placing table 54 is substantially the same as the temporary placing table 25, and has a lower case 61, a receiving member 62, stoppers 64, cylinders 64 and 65, and a lamp 66. An upper case 68 accommodating the ultraviolet lamp 67 is arranged above the temporary holder 54. The upper case 68 is divided into three parts in order to avoid interference with the suction member 52.

The suction member 52 that has sucked the uppermost separate sheet C at the supply station S1 once moves rightward to carry the separate sheet C into the sterilization station S3 and wait for a while. Meanwhile, the separate sheet C
Both upper and lower sides are sterilized. Thus, when sterilization is completed,
When the suction member 52 moves to the left this time and passes through the supply station S1 to reach the bottle loading station S2, the suction is released there to place the separate sheet C on the bottle B in the uppermost stage. Then, the bottle is extruded and stacked on the separate sheet C by a pusher (not shown).

[0023]

According to the present invention, the separate sheet is received by the receiving member of the temporary placing table while being conveyed from the separate sheet supply station to the bottle stacking station, and the separate sheet received by the receiving member is exposed to ultraviolet rays. Ultraviolet rays are radiated from the lamp and sterilized,
Since the positioning is performed by the positioning member, the sterilized separate sheet can be loaded on the pallet without recontaminating and without dropping the bottle.
