[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 to 3, a can body transporting apparatus X in which can bodies A such as beer cans are transported in multiple rows in an upright state, and can bodies A in adjacent rows are almost in abutting state at the end portions. Has a conveyor 1, a plurality of guide plates 4 provided on the conveyor 1, and a table 6 provided on the front side of the conveyor 1.

[0009] The conveyor 1 comprises a belt conveyor. As shown in FIG. 4, the conveyor belt 2 has a large number of grooves 3 on its surface and a width dimension capable of supporting a plurality of cans A. The guide plates 4 provided on the transport conveyor 1 are arranged in parallel, and form a can body transfer path 5 that can transfer the can bodies A in a line between the adjacent guide plates 4.

The leading ends of the plurality of guide plates 4 are located on the table 6 provided on the front side of the conveyor 1, and the leading end positions from the guide plates 4 on both sides to the center guide plate 4 in the can body transfer direction. It is located in front of. The table 6 is divided into front and rear portions, and comb-shaped guide teeth 7 provided at the upstream end of the upstream table 6a are inserted into grooves 3 formed in the belt 2.

For this reason, the can body A sent out from the conveyor 1 smoothly moves onto the upstream table 6a, is pushed by the subsequent can body A, and moves downstream.

A plurality of guide bars 8 are provided in the width direction of the upper surface of the downstream table 6b. The guide bar 8 is shown in FIG.
As shown in (1), the can body A that moves on the downstream table 6b is guided in contact with the lower tapered portion a. As shown in FIG. 1, each guide bar 8 is inclined inward, and the inclination angle is gradually increased toward the guide bars 8 on both sides. Therefore, when the can A is transported between the guide bars 8, the can A is shifted toward the center of the table 6 so that the outer peripheral surfaces are in contact with each other.

In place of the guide bar 8, the tips of the plurality of guide plates 4 are extended to above the downstream table 6b, and the extended portions are gradually reduced in thickness toward the tips.
The extended portion may be inclined inward in the same manner as the guide bar 8 so that the can bodies A substantially contact each other at the tip of the guide bar 8. In this case, the table 6 can be omitted.

As shown in FIG. 2, an upper stopper 9 and a lower stopper 10 are provided at the distal end of the downstream table 6b. These stoppers 9, 10 are advanced and retracted with respect to the can body transfer path by the operation of the cylinders 11, 12, respectively.
At the forward position, the can A is stopped on the downstream table 6b.

The double row of cans A stopped on the distal end of the downstream table 6b is taken out of the downstream table 6b by the suction and transport device 20 and transported into the box B which stands by below the downstream side.

As shown in FIGS. 1 and 2, the suction transfer device 20 is provided with a horizontally disposed rotating shaft 21 rotatably at the front side of the downstream table 6b, and a pair of rods at both ends of the rotating shaft 21. Fix the rear end of the guide member 22 of
A suction unit 23 is provided movably along the guide member 22.

The suction unit 23 includes a unit support member 24 movably supported along the guide member 22, a pad support member 25 provided at the rear end of the unit support member 24, and a pad support member 25. FIG. 2 is a diagram showing a plurality of can bodies A which are provided in the length direction and can simultaneously adsorb a plurality of rows of can bodies A stopped on the downstream table 6b, and the same number of suction pads 26 as the number of suction pads 26 provided on the front surface of the pad support member 25. The plurality of rods 27 shown in FIG. 3 are slidably inserted into guide cylinders 28 formed on the unit support member 24.

A spring 29 is supported on the rod 27, and the pad support member 25 is pressed toward the tip of the guide member 22 by the spring 29. Is in contact with the tip.

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

The oscillating device 31 converts the reciprocating motion of the first rod 32, which is reciprocated in the length direction by a cam mechanism or the like, into the rotational motion of the first shaft 34 via the first lever 33, and the
The rotation of the shaft 34 is transmitted to the rotation shaft 21 via the second lever 35, the second rod 36, and the third lever 37, and the rotation shaft 21 is repeatedly rotated by 90 °.

The suction unit 23 supported by the guide member 22 is moved by the moving device 41 to guide the guide member 2.
2 is reciprocated. The moving device 41 converts the reciprocating motion of the third rod 42 reciprocated in the length direction by a 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 suction unit 23 via the fifth lever 45 and the link 46.

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

The double row of cans A is fed from the discharge end of the conveyor 1 onto the upstream table 6a, pushed by the subsequent can A and sent from the upstream table 6a to the downstream table 6b. .

When the cans A move on the downstream table 6b, the lower rows of the cans A are guided by the guide bars 8 in the respective rows. At this time, since the guide bars 8 on both sides arranged in the width direction of the downstream table 6b are inclined toward the inside of the table 6, the double-row cans A are shifted toward the center of the downstream table 6b. As a result, the can bodies A come into contact with each other.

When the can A is conveyed to the distal end of the downstream table 6b, the can A is stopped by contact with 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 in a horizontal state, and the suction unit 23 is held at the retracted position.

The can A is moved to the tip of the downstream table 6b.
Is transported, and when the can A is stopped by contact with the upper and lower stoppers 9 and 10, the suction unit 23 moves forward by the operation of the moving device 41.

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 sucked, the upper and lower stoppers 9 and 10 are retracted from the can body transfer path, and then the suction unit 23 is moved to the horizontal guide member. Retreating along 22 and as shown by the dashed line in FIG.
The double-row cans A are taken out from the downstream table 6b forward.

When the can body A is taken out from the downstream table 6b, the upper and lower stoppers 9, 10 are set to face the can body transfer path, and the leading can body A on the downstream table 6b is moved to the succeeding can body. It is pushed by A and moves 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 that has retreated along the guide member 22 retreats after a predetermined stroke and stops, the pair of guide members 22 swings downward about the rotary shaft 21 by the operation of the swing device 31. The direction of the can A is changed by the swing.

As shown in FIG. 6 (II), when the pair of guide members 22 are swung by 90 ° to be in the vertical state, and when the can A sucked by the suction pad 26 is in the horizontal state, the guide member 22 moves. 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 A in the horizontal state is inserted into the box B waiting below, the suction of the suction pad 26 is released. After the suction is released, the suction unit 23 is raised, and when it is raised to a predetermined position, the guide member 22 is returned from the vertical state to the horizontal state, returns to the state of FIG. Of the can body A is continued.

[0033]

As described above, according to the present invention, cans are transported in multiple rows by the can transporter, and a plurality of cans arranged in a horizontal line at the end of the can transporter are suctioned by the suction transporter. Since the suction conveyance device is packed in the box, when the can body at the terminal end of the can body conveyance device is taken out by the suction conveyance device, the can body on the can body conveyance device corresponds to the diameter of the can body. By moving by a distance, it comes into contact with the stopper and is brought into a stopped state. For this reason, the time from the removal of the can body of the can body transfer device until the next can body comes into contact with the stopper is shorter than the time required for the suction conveyance device to pack the can body into a box, and the continuous operation of the suction conveyance device is performed. This makes it possible to carry out the can body packing operation more efficiently as compared with a conventional box packing apparatus in which can bodies are transported in a single vertical line and several can bodies are taken out from the top in a horizontal direction.

Further, if there is a gap between the cans of the double row of cans stopped at the end of the can transporter, the canisters are sucked by the suction transporter and packed in the box before being packed in the box. Although it is necessary to bring the bodies into contact with each other, the can bodies that stop at the end of the can body transporting device are in a state where the adjacent can bodies are almost in contact with each other. Can be packed in a box.

For this reason, it is not necessary to incorporate a mechanism for moving the can body suction pad in the width direction in the suction conveyance device.
The configuration of the suction conveyance device can be simplified.
