The figure which is provided in the front surface of the pad support member 25, which is provided in the length direction and is made up of the same number of suction bodies 26 as the storage bodies A capable of simultaneously suctioning the multiple rows of storage bodies A that are stopped on the downstream table 6b. A plurality of rods 27 shown in FIG. 3 are slidably inserted in a guide cylinder 28 formed in the unit support member 24.

A spring 29 is supported by the rod 27, the spring 29 presses the pad support member 25 toward the tip of the guide member 22, and the retaining projection 30 provided at the rear end of the rod 27 guides the guide cylinder 28. Is abutted to the tip of.

The guide member 22 is oscillated between the horizontal state facing the downstream table 6b and the vertical state extending downward by the operation of the oscillating device 31.

The rocking device 31 converts the reciprocating motion of the first rod 32, which is reciprocally moved in the lengthwise direction by a cam mechanism, into the rotary motion of the first shaft 34 via the first lever 33, and the first motion thereof is performed.
The rotation of the shaft 34 is transmitted to the rotary shaft 21 via the second lever 35, the second rod 36 and the third lever 37, and the rotary shaft 21 is repeatedly rotated 90 °.

The suction unit 23 supported by the guide member 22 is operated by a moving device 41 to guide the guide member 2.
It is reciprocated along 2. The moving device 41 converts the reciprocating motion of the third rod 42, which is reciprocally moved in the longitudinal direction by the cam mechanism or the like, into the rotational motion of the second shaft 44 via the fourth lever 43, and the rotation of the second shaft 44. The movement is converted into a linear movement of the adsorption unit 23 via the fifth lever 45 and the link 46.

Now, when a large number of can bodies A are supplied onto the supply end portion of the transport conveyor 1, these can bodies A are transported forward by the movement of the transport conveyor 1 and are formed between the guide plates 4. It is transferred in a single row along the can body transfer path 5, and is transferred in a double row on the conveyor 1.

The cans A in the double row state are fed from the discharge end of the conveyor 1 onto the upstream table 6a, pushed by the succeeding cans A and fed from the upstream table 6a to the downstream table 6b. .

When the can bodies A move on the downstream side table 6b, the guide bars 8 guide the lower tapered portions a of the can bodies A in a plurality of rows. At this time, since the guide bars 8 on both sides lined up in the width direction of the downstream table 6b are inclined inward of the table 6, the double-row can bodies A are moved toward the center of the downstream table 6b. The same as can body A
The men touch each other.

When the can body A is conveyed to the tip of the downstream table 6b, the can body A is stopped by abutting against the upper stopper 9 and the lower stopper 10.

At this time, the pair of guide members 22 of the suction conveyance device 20 are held horizontally, and the suction unit 23 is held at the retracted position.

When the can body A is conveyed and abuts against the upper and lower stoppers 9 and 10, the can body A is stopped.

The suction pad 26 of the suction unit 23 is shown in FIG.
As shown in (I), when the can body A is brought into contact with the can body A and the can body A is adsorbed, the upper and lower stoppers 9 and 10 are retracted from the can body transfer path, and then the adsorbing unit 23 is in a horizontal guide member. 22 as shown by the chain line in FIG. 6 (I),
The double-row can bodies A are taken out forward from the downstream table 6b.

When the can body A is taken out from the downstream table 6b, the upper and lower stoppers 9 and 10 are brought into a state of facing the can body transfer path, and the leading can body A on the downstream table 6b is the succeeding can body. It is pushed by A and moved by a distance corresponding to the diameter of the can body A, and is held in a stopped state by contact with the upper and lower stoppers 9 and 10.

On the other hand, when the suction unit 23 retracted along the guide member 22 moves backward for a predetermined stroke and then stops, the rocking device 31 operates to rock the pair of guide members 22 downward about the rotary shaft 21. The swinging causes the orientation of the can body A to be changed.

As shown in FIG. 6 (II), when the pair of guide members 22 are swung 90 ° to be in a vertical state and the can body A sucked by the suction pad 26 is in a horizontal state, the movement is made. By the operation of the device 41, the suction unit 23 is lowered along the guide member 22 in the vertical state.

When the can body A in the horizontal state is inserted into the box B standing by therebelow, the suction of the suction pad 26 is released. After the suction is released, the suction unit 23 is raised, and when the suction unit 23 is raised to a predetermined position, the guide member 22 is returned from the vertical state to the horizontal state and returned to the state of FIG. 1, and the next operation is repeated by repeating the same operation as described above. Boxing work of the can body A is continued.

[0033]

As described above, according to the present invention, the can bodies are conveyed by the can body conveying device in a plurality of rows, and the plurality of can bodies arranged side by side at the end of the can body conveying device are adsorbed by the suction conveying device. Since it is sucked and conveyed and packed in the box, when the can body at the end of the can body carrier is taken out by the suction carrier, the can body on the can body carrier corresponds to the diameter of the can body. By moving by a distance, it comes into contact with the stopper and is stopped. For this reason, the time from the removal of a can of the can carrier to the contact of the next can with the stopper is shorter than the time required for the suction carrier to pack the can in a box, and the continuous operation of the suction carrier. Therefore, it is possible to efficiently carry out the box packing work of the cans as compared with the conventional boxing apparatus in which the cans are conveyed in a vertical line and several cans are taken out from the top in the horizontal direction.

Further, if there is a gap between the can bodies of the multiple rows of can bodies that stop at the terminal end of the can body transporting device, the can transporting device can suck the can bodies in one horizontal line and pack them into the box. It is necessary to bring the bodies into contact with each other, but the can bodies that stop at the end of the can body transport device are in a state where adjacent can bodies are almost in contact with each other. Can be boxed.

Therefore, it is not necessary to incorporate a mechanism for moving the can suction pad in the suction conveyance device in the width direction,
It is possible to simplify the configuration of the suction conveyance device.
