Description

[Detailed description of the invention] The present invention is an automatic can lid supply system that, after being fitted into the can mouth, expands the diameter of the peripheral wall and supplies the can lid to a predetermined position. It is related to the device.

There is a can lid made of a thin steel plate that is fitted into the can opening 2 and attached to the can opening 2 by expanding the diameter of a part of the peripheral wall 1A, as shown by reference numeral 1 in Fig. 1. As is well known.

On the other hand, after filling the contents, the can lid 1 is fed to the can mouth 2 by placing the lower end of the chute 5 in a fixed position above the transfer line 4 of the can body 3, as shown in FIG. Can body 3 is kept and transported intermittently.
If the can lid 1 is dropped and fed from the chute 5 to the can mouth 2 of the chute 5, it becomes possible to automate the work, and it is also easy to link with the next process, that is, the can lid fixing process using a crimper. The work will not go smoothly unless a sufficient amount of can lids 1 are stored on the side.

In view of this, this proposal provides an automatic can lid supplying device that satisfies the above conditions. spiral guide rails facing parallel to each other at intervals of and a chute with its lower end facing above the fixed position for supplying the can lid to the can mouth.

Next, an embodiment of the present invention will be explained with reference to the drawings. Fig. 3 shows a partially omitted plan view,
The device according to the invention, shown in side view in FIG. 4, comprises an endless belt 6, a spiral guide rail 7 and a chute 8.

The endless belt 6 is stretched around a pair of pulleys 9 and 10, and has a large number of magnets 11 facing the back sides of the ascending part 6A and descending part 6B, and magnets 12 embedded all around the pulleys 9 and 10. surface 6
The can lid 1 can be magnetically attracted to all positions a.

Pulley 9 is a drive-side pulley, and is a pulley for chain 1.
3 to a motor 15 with a speed reducer 14.

The spiral guide rail 7 is an elongated plate with a vertically elongated rectangular cross section as shown in FIG. 5a, or as shown in FIG. 5b.
A single metal rod as shown in the figure is used to extend parallel to the surface of the endless belt 6 at a predetermined interval, and is bent into a deformed spiral shape facing diagonally forward and laterally at a predetermined angle with respect to the belt motion direction of the endless belt. The can lid 1 is a rail that supports the outer peripheral edge or peripheral wall portion 1A of the curled portion 1B of the can lid 1 and magnetically attracts the bottom surface 1C to the surface 6a of the endless belt 6, as shown in FIGS. 5a and 5b. As the endless belt 6 moves, it has a function of sequentially moving to one side while causing a slip between the endless belt 6 and the endless belt 6.

The chute 8 is the spiral guide rail 7
At the end of the can lid, the upper end faces the can lid so that it can be scraped off freely, and the lower end faces the can lid supply fixed position (corresponding to chute 5 in Fig. 2), and near the lower end there is a proximity switch 1.
6 is provided.

The proximity switch 16 is a switch that detects that the chute 8 is filled with the can lid 1 and outputs a signal to stop the rotation of the pulley 9.

Since the present invention has the above-mentioned configuration, when the endless belt 6 is moved and the can lid 1 is fed toward the starting end of the spiral guide rail 7, the can lid 1 is brought into contact with the surface 6a of the endless belt 6 and the bottom surface 1c. While being guided by the spiral guide rail 7 while being magnetically attracted, it gradually moves to the side, and eventually reaches the end of the spiral guide rail 7.

Since the upper end of the chute 8 faces the end of the spiral guide rail 7 and allows the can lid 1 to be scraped off, the can lids that reach the end of the spiral guide rail 7 sequentially move to the chute 8 and slide down. The liquid then falls into the mouth of the can (see Figure 2) below.

As is clear from the above description, the present device can magnetically attract and store a large amount of can lids, and sequentially supply them to the mouth of a can body in a fixed position. , can work completely unattended,
This is extremely useful and advantageous in terms of labor saving and associated economicalization.
