Problems solved by technology

Although almost all kinds of foreign matter were mostly removed on the back side of the cover, on the front side of the cover, especially paper dust and aluminum dust remained partly, and the removal rate was 76%, and the original goal was not achieved.

Embodiment 1

[0042] Using the foreign matter removal device for container caps shown in FIG. 1 , the following experiments were conducted to confirm the state of removal of foreign matter. As an experiment, 10 can lids were used as a group, wherein each lid was attached with 60 aluminum scraps on its surface and back, and put into the upstream side chute, and pulled out from the downstream side chute, and The number of foreign substances remaining on the front and back of each cap was counted. As the air injection condition from the air nozzle at this time, the injection pressure is set to 1.0kg / cm 2 , The total injection volume is 1000L / min, and the suction volume of the suction passage is set to 6000L / min for the experiment. As a result, as shown in Table 2, there was no residual aluminum dust attached to the surface, and only one lid with one aluminum dust attached to the back was observed. Thus, the aluminum dust was almost completely removed, and it was difficult to completely remove...

Embodiment 2

[0046] In addition, experiments were carried out under the same conditions as in Example 1 using the apparatus shown in FIGS. 3 and 4 . The results are shown in Table 3. As a result, it was confirmed that the devices shown in FIGS. 3 and 4 were mostly removed, although the removal rate was lower than that of Example 1. According to the above results, it can be confirmed that although it is most effective to set the local concentration passage, the clearance rate also becomes high due to the situation of Example 2 compared with the comparative example shown in Table 1, and it is usually not as carried out in the experiment. Since a large amount of foreign matter adheres to the cover, it can be sufficiently used for practical use.

Abstract

The present invention provides a small and inexpensive foreign matter removal device for container caps that reliably removes foreign matter such as paper dust from the container cap by jetting air. Foreign matter adhering to the inner and outer surfaces of container caps conveyed by the screw at predetermined intervals in the foreign matter removal chamber is sprayed with air from the air nozzle, and the foreign matter adhering to the inner and outer surfaces is removed, and the air that has passed between the caps is sucked into the cap and the air nozzle. It can be effectively cleared without spreading into the room or generating backflow in the local concentration passage arranged opposite to and close to the passing cover. The air in the indoor space that does not face the opening of the funnel of the local concentrating passage is sucked into the suction passage through the gap in the outer periphery of the local concentrating passage, thereby removing foreign matter separated from the cap. Since the external air inlet is provided, it is possible to increase the suction amount of the dust collector to be larger than the supply amount from the air supply pipe without impairing the stable conveyance of the cap by increasing the air volume passing through the cap.

Description

technical field [0001] The present invention relates to a container cap foreign matter removal device for removing foreign matter attached to container caps such as can caps. Background technique [0002] Conventionally, various methods and devices for cleaning container caps such as metal caps and synthetic resin caps supplied to crimping devices or capping machines before being attached to containers have been proposed. For example, there has been proposed a method of transporting container caps (hereinafter simply referred to as caps) of can caps supplied to the crimping device at predetermined intervals while rotating them, and irradiating the inner and outer surfaces of the caps with ultraviolet light during the transport to sterilize them. (For example, refer to Patent Documents 1 and 2), or a method of spraying washing water to clean the caps that are conveyed while rotating while maintaining the same interval (for example, refer to Patent Document 3), or spraying and...
