According to this apparatus configured in this way, packaging can be performed continuously in the following manner.

Initially, the air cylinder 16a of the first pusher device 8 protrudes its piston rod and the swing base 1
5a upward at an angle (θ), and the first pusher 18a is moved so that the air cylinder 17a sinks its piston rod and the partition plate 19a is positioned above the conveyor 1b. There is.

Similarly, the air cylinder 16b of the second pusher device 9 protrudes its piston rod to swing the swinging base 15b upward at an angle (θ), and the air cylinder 17b sinks its piston rod to partition it. Board 19
The second pusher 18b is moved such that the second pusher 18b is positioned above the conveyor 1b.

In addition, the air cylinder 21a of the first stopper device 6
The air cylinder 21b of the second stopper device 7 also sinks the piston rod to move the first stopper 22a and the second stopper 22b onto the machine base 13.

Furthermore, the air cylinder 24a at the first article receiving position 23
protrudes its piston rod and moves to the first article receiving position P1.
While the first movable table 10 is being moved to the second article receiving position P2, the air cylinder 24b of the second article receiving belt 25 also protrudes its piston rod to move the second movable table 11 to the second article receiving position P2.

Note that the second detection device 5 has stopped projecting light onto the first horizontal conveyor line 1.

When the drive belt conveyors la and lb constituting the first horizontal conveyor line 1 are driven and the bagged articles 2 are placed at regular intervals and conveyed, the first detection device 4 detects this.

When the leading bagged article 2 is detected in a shielded manner at this first detection point, the air cylinder 21a of the first stopper device 6 projects its piston rod.

As a result, the first stopper 22a is moved horizontally and positioned above the conveyor 1b, and this stopper 22a is moved horizontally and positioned above the conveyor 1b.
The first bagged article is locked at point a.

Next, the air cylinder 16a sinks its piston rod, and the swing base 15a, which had been swung upward, is swung downward to a horizontal state, and is moved onto the conveyor 1b as shown in FIG. A partition plate 19a of the first pusher 18a is positioned.

Then, after a certain period of time has elapsed, the second bagged article 2 that is subsequently conveyed is detected by the first detection device 4,
After a predetermined period of time has elapsed after this detection, the air cylinder 17
a projects its piston rod, and the first pusher 18a is moved horizontally while positioning the partition plate 19a between the bagged articles 2 as shown in FIG.

As a result, the first pusher 18a is positioned on the first movable table 10, and the two bagged articles 2 are transferred to AI and A2 on the first movable table 10.

Next, the air cylinder 16a protrudes its piston rod, and the swing base 15a is again swung upward, and the air cylinder 17a retracts its piston rod, and the first pusher 18a is moved to its original position.

The third bagged article 2 that is subsequently transported is immediately after the first pusher 18a, which is being moved onto the first movable table 10, is swung upward in the first transfer described above. It is detected by the first detection device 4 and transported downstream.

During this time, the first stopper 22a of the first stopper device 6 remains moved onto the conveyor 1b, so that the third bagged article 2 being conveyed is stopped.

Thereafter, the second transfer can be performed in the same manner.

By this second transfer, the third and fourth bagged articles 2 are transferred to A3 on the first movable table 10. Transferred to A4.

Note that when the second transfer is completed and the first pusher 18a is moved from the first movable table 10 to its original position on the machine platform 13 side, the air cylinder 21a of the first stopper device 6 is moved to its piston rod. When the stopper 22a is moved from the conveyor 1b to the machine stand 13, the first detection device 4 stops emitting light.

Subsequently, the second pusher device 9 disposed on the upstream side performs the transfer.

When the fourth bagged article 2 is detected by the first detecting device 4, the second detecting device 5 emits light, and the subsequently transported fifth bagged article 2 is detected at this second detection point. Detected in

Then, the air cylinder 21 of the second stopper device 7
b protrudes its piston rod, thereby moving the second stopper 22b in the horizontal direction and moving the conveyor 1b.
The stopper 22b is positioned upward, and the fifth bagged article 2 is stopped by this stopper 22b.

Next, the second pusher 18b of the second pusher device 9
The second article receiving position P2 is controlled in the same way as the pusher control in the first pusher device 8 described above.
The bagged article 2 is placed on the second movable table 11 which is being moved to
can be transferred to a designated location.

That is, in the first transfer, the 5th and 6th bags 2 are transferred to Bl and B2 on the second movable table 11, and in the second transfer, the 7th and 8th bags are transferred. Filling item 2 with B
3. It can be transferred to B4.

Note that when the eighth bagged article 2 is detected at the second detection point, the first detection device 4 emits light again, and therefore, the first pusher device 8 subsequently performs the transfer as described above. I can do it.

Note that when the eighth bagged article 2 passes through the second detection point, the second detection device 5 stops emitting light.

Further, in the second transfer by the second pusher device 9, when the second pusher 18b is moved onto the second movable table 11, the air cylinder 21b of the second stopper device 7 sinks its piston rod, As a result, the second stopper 22b is moved from the top of the conveyor 1b to the machine base 13.
be moved up.

Therefore, after the transfer by the second pusher device 9 is completed, the transfer by the first pusher device 8 can be performed subsequently.

On the other hand, the bagged article 2 transferred onto the first movable table 10
The group is moved by a second movable table 1 by a second pusher device 9.
During the transfer onto the first cargo handling device 26, the first cargo handling device 26 packs the cargo into a box.

The empty box 12 opened during the transfer by the first pusher device 8 is the first and second article receiving position PI.

First and second movable tables 10.11 located at P2
The second horizontal conveyor line 3 conveys the product downward.

Although not shown, the conveyor 3b constituting the second horizontal conveyor line 3 is provided with a photocell detection device for detecting empty boxes 12, a stopper device that operates based on a detection signal from this device, and the like. The empty boxes 12 being transported are always stopped at a predetermined position.

While the empty box 12 is prepared in this way, when the transfer of the four bagged articles 2 onto the first movable table 10 is completed and the first pusher 18a is moved to the machine stand 13 side, The air cylinder 28a of the first material handling device 26 protrudes its piston rod and lowers the vacuum suction gripper 29a to grip the two groups of bagged articles.

Then, the air cylinder 24 at the first article receiving position 23
a sinks its piston rond, and the first movable table 10
is moved horizontally to the machine stand 13 side.

At this time, the first movable table 10 moves horizontally between the upper and lower surfaces (transport surface side and return surface side) of the conveyor 1b - its tip is between the upper and lower surfaces (transport surface side and return surface side) of the conveyor 1b. It is moved horizontally until it is submerged.

As a result, a passage is formed where the first movable table 10 was located, and when the air cylinder 28a of the first cargo handling device 26 further protrudes from its pit rod, the vacuum suction gripper 29a moves from the passage into the empty box 12. In this state, by releasing the suction grip, the second group of bagged articles can be boxed.

The vacuum suction gripper 29a that has finished packaging is moved upward again by the air cylinder 28a, and then the first movable table 10 is moved to the original first article receiving position P1 by the air cylinder 24a.

Packing of the second group of bagged articles by the second cargo handling device 30 can be performed in the same manner.

This is done after the second pusher device 9 finishes transferring onto the second movable table 11, and while the second cargo handling device 30 is packing, the first pusher device 8 moves to the second movable table 11. 1. Transfer onto the movable table 10 can be performed.

When a predetermined number of items are packed into the two empty boxes 12 in this way, the conveyor 3b is driven, and the items are transported to another location via the third conveyor line 31 connected thereto, and are then packed in boxes. Two empty boxes 12 are sent to the conveyor 3b by the drive of the conveyor 3a.

In FIGS. 1 and 2, 32 is a guide, and 33 is a fourth conveyor line. The guide 32 guides the bagged articles 2 being transferred, and the fourth conveyor line is used to convey defective products, etc. used for.

(Effect of the invention) As described above, according to the present device, the first pusher device 8
The bagged article 2 was transferred onto the first movable table 10 by
While the group is packed into the empty box 12 by the first cargo handling device 26, the second movable table 11 is moved by the second pusher device 9.
Transfer the two groups of bagged articles upward, and move the two groups of bagged articles on the second movable table 11 to the empty box 12 using the second cargo handling device 30.
Since the first pusher device 8 can transfer the two groups of bagged articles onto the first movable table 10 while stuffing them inside, more bagged articles 2 can be boxed per unit time. I can do it.

Regarding the first and second pusher devices 8 and 9, the pushers 18ay18b are moved to the first and second movable tables 10.1.
When moving from the top of the first horizontal conveyor line 1 to the side of the machine 13, the bagged articles 2 can be transported while being placed at smaller intervals on the first horizontal conveyor line 1. Therefore, more bagged articles 2 can be delivered to the first and second movable tables 10.11 per unit time.
It can be transferred above.

Furthermore, the two bags filled items are transferred onto the first and second movable tables 10.11 so as not to be stacked together, and the first and second suction grippers 29a and 29b are moved up and down and the first and second movable tables 10.11 are moved. Since the empty boxes 12 can be filled by moving the boxes 11, there will be no cargo handling troubles such as collapse of the cargo during packing, and the boxes can be packed easily.
