Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a can lid sorting device for sorting a predetermined number of can lid groups from a stocker to a plurality of conveyors.

Conventionally, in this type of device, as an example of a method for feeding can lids to a plurality of seamers, a plurality of aligned can lid groups (generally about 200 can lids) are stocked in a single line in a supply path, and the can lids are There was one in which the group was rolled along the supply path and distributed to conveyors for multiple seamers.

However, with the above-mentioned method of rolling a group of can lids, the adjacent can lids dig into each other due to the impact, causing the lid group to collapse or topple over, resulting in interruptions in sorting to the conveyor. In the case of can lids with tabs, this problem was severe and could even lead to defective products.

On the other hand, it is also possible to distribute the can lids from their standby position to the conveyor in a stationary state without rolling them.
This case had the disadvantage of being mechanically very difficult.

An object of the present invention is to abolish the sorting of can lid groups due to transfer, and to remove the sorting of can lid groups from a stocker in which groups of can lids are stocked in a series and having a slideable pocket by falling into a device by its own weight. By using a system in which the can lids are transferred to each conveyor by their own weight, the can lids can be sorted continuously, stably, and reliably without collapsing or falling down due to the group of can lids being bitten. It is about providing.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows the main mechanism of the entire apparatus of the present invention.

In the figure, the sorting equipment includes a stocker A where groups of can lids are serially stocked in a single row, and a conveyor B placed below this where the groups of can lids are sorted into multiple rows and transported to a seamer, for example. , is arranged between the stocker A and the transport conveyor B, and is composed of a sorting device C for distributing groups of can lids from the stocker to the transport conveyor.

Each of the above configurations will be explained in detail below.

The stocker A has an inclined supply path 2 in which generally 200 aligned can lid groups 1 are stocked in a single row.

The can lid group 1 in the front row collides with a release plate 4 which is opened and closed by the operation of the cylinder 3, and normally the feeding of the can lid group is prevented.

Further, the IJ IJ-sprate 4 is provided with a limit switch 5 for detecting its closure, and is also provided with a phototube 6 for roughly detecting the presence or absence of the can lid group 1.

The conveyor B is arranged below the stocker A, and in the embodiment, three rows of guide conveyors 7a, γb, 1
It consists of c.

Each guide conveyor 7a + γb, 7c is partitioned by a frame 8, and the guide conveyors 1a, γb and 1
The frame body between b and the IC is a high extending frame 8a, 8b.
have.

Moreover, each of the above-mentioned guide conveyors γa. 7b and 7c are proximity switches 9a that detect that the can lid group 1 is being conveyed.
, 9b, and 9c.

Note that the can lid groups on each guide conveyor are transferred to a seamer (not shown) provided for each.

The sorting device C is disposed between the stocker A and the transport conveyor B, and is slidable in a direction across each guide conveyor γa p 7 b pγc by operating the cylinder 10.

The sorting device C has two left and right pockets 12 and 13 separated by a partition plate 11, in which can lid groups 1 from the stocker A can be stored separately.

The lower end of the partition plate 11 hangs down for a long time so as to be close to the frames 8a and sb that partition the guide conveyor.

The lower bottom of both pockets 12.13 is a release plate 14.15, one end of which is supported on the frame of the pocket, and the free ends of these release plates are attached to the partition plate 1.
They face each other with 1 in between.

Both release plates 14 and 15 are connected to the cylinder 16.
It can be opened and closed by operating 17.

Further, both release plates 14, 15 are provided with limit switches 18, 19 for detecting the closing of the release plates 14, 15, and phototubes 20, 21 for detecting that the can lid group 1 is accommodated in both pockets 12, 13. .

Furthermore, limit switches 22 and 23 are arranged outside the frame of both pockets 12 and 13, respectively.

For example, when sorting, device C slides into one pocket 1.
When frame 2 comes into contact with limit switch 22 (
1 position), it becomes possible to supply can lid group 1 from stocker A to the other pocket 13, and both pockets 1
2°13 is located directly above the guide conveyors 7a and 7b,
Further, when the frame of the other pocket 13 comes into contact with the limit switch 23, it becomes possible to supply the can lid group 1 from the stocker A to the one pocket 12, and both pockets 12 and 13 are transferred to the guide conveyors 7b and 7c. It is located directly above the .

Note that 24 and 25 are guide plates for smoothly supplying the can lid group to the pocket.

Next, the operation of distributing can lid groups according to the present invention will be explained with reference to FIGS. 2 to 6.

As shown in FIG. 2, in the standby state where the can lid group 1 is present in the pockets 12, 13 and the guide conveyors 7a, 7b, 7c, the can lid group on the guide conveyor 7c is now consumed and its proximity switch 9c When the limit switch 23 and the phototube 21 of the pocket 13 are turned on, the cylinder 11 operates and the IJ is turned off (see Fig. 3).
The IJ-spray plate 15 is opened, and the can lid group 1 in the pocket 13 is transferred onto the guide conveyor IC.

When this group of can lids is detected by the proximity switch 9c, the release plate 15 closes (see FIG. 4).

Next, a group of can lids is supplied to the empty pocket 13.

That is, the release plate 1 of both pockets 12.13
4.15 is confirmed to be closed by the limit switches 18 and 19, and the phototube 21 of the pocket 13 is OFF, the cylinder 10 operates to slide the pocket 13 to a position where can lids can be supplied from the stocker A, The limit switch 22 comes into contact with the frame of the pocket 12 and turns on.
Then, the cylinder 3 operates to release the release plate 4 (see Fig. 5), and the pocket 13 is removed from the stocker A.
The can lid group 1 is housed inside (see FIG. 6).

Then, the next can lid group 1 is waiting in the stocker A.

Thereafter, when the group of can lids on the guide conveyors 7a, 7b, and 7c are consumed, the sorting device C performs the same operation as described above, and this process is repeated.

Here, to explain how a group of can lids is transferred from the pocket to the guide conveyor, for example, as shown in Figure 3,
When the release plate 15 of the pocket 13 begins to open, the can lid group 1 descends while being guided by the wall surface of the partition plate 11, and when the plate 15 is completely opened, it is transferred to the guide conveyor 7c along the frame 8b. It is.

In addition, limit switches 18, 19 and 22゜23,
Phototubes 20, 21. Proximity switch 5aysb.

9c are interlocked with each other, and since these wiring circuits are normal circuits, they are omitted.

Further, in the embodiment of the present invention, the case where the can lid groups are sorted into three rows has been described, but it is also possible to sort them into two columns or to sort them in four or more ways.

As described above, according to the present invention, a group of can lids in a single row is once sorted from the stocker by its own weight, and stored in the pocket of the device.
By transferring from here to multiple conveyors,
Sorting of can lid groups due to transfer is eliminated, and as a result, it is possible to realize a distribution that does not cause the can lid groups to collapse or fall down due to mutual digging.

Furthermore, when transferring from the pocket to the conveyor, the group of can lids is moved along the wall of the partition plate, so the group of lids does not become disordered, and even if some disorder occurs, it is corrected by the partition plate. It is possible to do so.

Furthermore, the above-mentioned sorting device has a short operating distance and is excellent in high-speed response, making it possible to always stock a group of can lids in one of the pockets, which frees up supply to the conveyance line. As a result, the transfer to the conveyor can be performed relatively slowly, which not only prevents the group of can lids from being disturbed or collapsed, but also enables continuous supply. It has great practical effects, such as being located directly above the conveyor, requiring only as much installation space as the number of conveyors, and even more than four types of sorting can be done with the same configuration.
