The work of housing can lids into conventional carton cases of this type has generally been carried out manually. In other words, in the can manufacturing industry, where mechanization has progressed significantly, for example, can lids after press processing are arranged in a horizontal cylindrical shape in multiple layers, and then, for example, 150 lids are manually picked up and arranged and stored in a carton case. The current situation is that it is still carried out by inefficient manual labor. This operation of removing lids is inaccurate because the number of can lids picked up is determined by the operator's guess, and therefore, there is a drawback that accurate counting control is insufficient when taking inventory of can lids.

The present invention aims to solve the above-mentioned conventional drawbacks, and aims to save labor by automating the storage of can lids in a carton case, and also enables accurate counting and management of can lids. The purpose of the present invention is to provide an automatic lid packaging device.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a holding flap for arranging can lids conveyed one by one from a chute (not shown) into a group C of can lids in which a large number of can lids are stacked and arranged in a horizontal cylindrical body. , a pair of left and right inverted eight-shaped flap plates 2, 2 are supporting parts 1a, 1a.
It can be opened as shown by the imaginary line.
Also, a counter roll 3 is installed at the entrance of the flap 1.
is provided, and the can lids passing therethrough are counted one by one, so that the number of can lids C on the flap 1 can be accurately read.

Beneath the flap 1, there is a conveyance path 4 for conveying a group of cylindrical can lids C that is tilted slightly higher forward in a direction perpendicular to the flap, and a distribution path branching out to the rear of this conveyance path. A conveyance path 5 is provided.

A pusher 6 is disposed on the conveyance path 4 to push forward the can lid group C conveyed thereon. This pusher is connected to a cylinder 7 via links 6a and 6b, and can be slid along the conveying path 4 about a fulcrum 8 by operating the cylinder. Slightly above the front of the pusher 6 is a swingable lever 9.
is arranged, and the can lid group C from the flap 1 is temporarily received by the lever 9 and the pusher 6. Therefore, lever 9 and pusher 6
The group C of can lids shown by the imaginary line, which is held by the can lids, can be transferred to the starting end on the conveyance path 4 by swinging the lever 9 in the direction of the arrow. Further, a stopper 10 is provided slightly in front of the conveyance path 4, and this stopper is stretched rearward by spring means (not shown).

The starting position of the cylinder 7 is when the pusher 6 is slightly advanced to the solid line position in FIG. , 13 are arranged.

In FIG. 2, 14 is a lid detection sensor that operates the lever 9, and 15 is a lid detection sensor that advances the pusher 6 to the stopper 10. At this time, the pusher 6 operates the limit switch 12 to move backward. Reference numeral 16 denotes a lid detection sensor for confirming the four rows of can lids on the conveyance path 4. The pusher 6 is advanced far to the end of the conveyance path 4, and at this time, the limit switch 13 is activated to move backward, and the limit switch 11 is activated. operate. This limit switch 11 prevents the lever 9 from swinging while the pusher 6 is in operation.

On the other hand, in front of the conveyance path 4, a carton case 18 is positioned on the box conveyance path 17, and a lift mechanism 19 is provided below the carton case 18. The lift mechanism includes a lift plate 22 on a rod 21 of an upright cylinder 20, and a plurality of bush rods 23 embedded in the lift plate 22. Each bushing rod 23 has 1 carton case
It is inserted into a rod hole 24 opened at the bottom of the carton case 8, and pushes up a bottom plate 25 inside the carton case 18. In addition, 26 is a cover detection sensor provided on the upper edge of the carton case 18, and the cylinder 20 is lowered in stages by the operation of this sensor. Additionally, four limit switches 27, 28, 29 and 30 are provided in stepwise contact with the lift plate 22 of the cylinder 20.
A limit switch 30 among them operates to detect when the carton case 18 is full of can lid groups C. Further, 31 is a lid holding cylinder arranged above the carton case 18, and 32 is a lid holding plate that descends. Further, in this embodiment, the lift plate 21 is raised and lowered by the cylinder 20, but the present invention is not limited to this, and it is possible to change the lift plate 21 as appropriate, such as using four chains operated by a motor.

Next, a method and operation for arranging and accommodating a plurality of can lid groups C in the carton case 18 will be explained.

When, for example, 150 can lids are collected in the group C of can lids that are conveyed from the chute, counted one by one, and arranged in a cylindrical shape on the flap 1, the flap 1 opens and is received by the pusher 6 and the lever 9. As a result, the lid detection sensor 14 detects the presence of the can lid group C,
The lever 9 swings and the group of can lids is transferred onto the starting end of the conveyance path 4. Then, when the can lid group C is transferred to the starting end of the conveyance path 4, the lid detection sensor 15 detects the presence of the can lid group, the cylinder 7 is activated, and the pusher 6 advances to the stopper 10, whereby the can can The lid group C is pushed out by the pusher 6 and is stopped by being engaged with the stopper 10. The pusher contacts the limit switch 12 and retreats.

In this way, when the next group of can lids is pushed out by the pusher 6 by the same operation as described above, the next group of can lids is stopped by the stopper 10, and the previous group of can lids C moves forward by one row. By repeating this action,
When four rows of can lid groups C are arranged on the conveyance path 4 in front of the stopper 10 as shown in FIG. The group of can lids in the row is transferred to the conveyance path, and the group of can lids in the fifth row is pushed out by the pusher 6, and the group of can lids in the fifth row is transferred to the carton case 1.
It is housed on the bottom plate 25 in the 8.

When the can lid group housed on the bottom plate 25 is detected by the lid detection sensor 26, the lid holding cylinder 31 is activated, and the lid holding plate 32 moves in conjunction with the cylinder 20 while holding down the five rows of can lid groups. Lift plate 2
Lower 2 by one step. When the lift plate 22 comes into contact with the limit switch 28, the lift plate 22 stops and the lid holding plate 32 returns to its original position to prepare for storing the next group of five rows of can lids.

When the series of operations described above is repeated, the can lid groups C in five rows and three tiers are housed in an array in the carton case 18, and the carton case 18 becomes full. After the can lid group C is full, the actual carton case is replaced with an empty carton case, and the can lid group starts to be accommodated in the carton case again.

FIG. 3 shows the operating state of the line device in which the carton case 18 is transported from an empty box to a full box. As shown in FIG.
8a is being fed. The empty carton case 18a at the forefront of these is the cylinder 3 that has been extended.
It is riding on the push plate 35 of No. 4. Thus, as described above, when the carton case 18 is full of can lid groups C and the limit switch 30 is activated, the cylinder 34 is activated in conjunction with this, and the push plate 35 is moved backward. As a result, the empty carton case 18a at the forefront moves onto the box transport path 17,
The limit switches 36 and 37 confirm that the empty box has been fed (see FIG. 3b). In this way, the forward movement of the push plate 35 moves the empty carton case 1 to the forefront.
8a is pushed out, and the actual box is transferred to the actual box conveyance path 3.
8 (see Figure 3c).

In the automatic can lid packaging device of the present invention, the can lid group C accommodated in the carton case 18 is continuously transferred through the line equipment, but it is not possible to extract any can lid group from among the can lid groups C. It is possible to conduct an inspection. That is, when the group of can lids is received by the pusher 6 and the lever 9, if the lever 9 is automatically or artificially fixed and the cylinder 7 is operated to move the pusher 6 forward, the group of can lids will be moved forward. It can be transferred onto the sorting conveyance path 5, and sampling inspection can be easily performed.

In addition, when packaging can lids, the arrangement of the can lids in the carton case is described as five rows and three tiers in the example, but it is not limited to this, and can be arranged freely depending on the size of the case. As described above, according to the present invention, it is possible to automate the storage of can lids into carton cases, thereby achieving labor saving and efficient box packing. The effects are truly significant, such as the ability to accurately count the lids and ease handling during inventory.
