JPS628914A - Aligning method for caps - Google Patents

Abstract

PURPOSE:To make improvements in aligning efficiency, by leading a lot of caps into a clearance between a disc outer circumferential part and a cylindrical wall and aligning them in a state of being slung, by means of rotation of a feeder disc where a large number of pump-type caps to be attached to a bottle are thrown in. CONSTITUTION:When many caps 6 are thrown in a lowermost part of a tilted feeder disc 2 of an aligning device 1 by a carrying-in device, these caps 6 move in both radial and rotational directions as being rolled on the said disc 2 with rotation of the feeder disc 2. And, they reach to an annular cap aligning clearance 3 formed between an outer circumferential part of the disc 2 and a cylindrical wall 4 along this outer circumferential part. This clearance 3 is set in size to be smaller than an outer diameter (a) of a cap body 61 and larger than an outer diameter (b) of a cylinder 62 so that these caps 6 are aligned in a state of being slung at the clearance 3 and transferred, thus they go over a topmost part of the disc 2 and are discharged out of a takeout guide 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for aligning caps, and in particular,
Among the caps that are randomly supplied in either direction, such as forward or reverse, the caps that are supplied in the reverse direction are aligned using the center of gravity of the caps, and the caps that are supplied in the normal direction and the caps that are supplied in the reverse direction are aligned. The present invention relates to a cap alignment method for transferring supplied and aligned caps to a next process such as a capping process.

[Conventional technology]

The functions of cappers for bottles can be divided into lining and supplying caps and camping work (driving or screwing), but the method of lining and supplying caps depends on the shape, dimensions, material, and capper capacity of the caps. In general, methods such as center of gravity type, hanging type, vibrating type, and pocket feeder set are often adopted.

In addition, various methods of arranging and supplying caps having a pump function have been adopted. For example, as a method of arranging and supplying trigger type caps, as shown in FIGS. 14 and 15, Cylindrical wall 4
By rotating the feeder disk 2,
A method of arranging the caps 6 in an inverted manner is known.

Furthermore, as an alignment and feeding device for rod-shaped articles having an enlarged head (for example, the cap shown in FIG. 17),
A device described in Japanese Patent No. 9-88020 is known, and this publication describes an aligning and feeding device in which a large number of fins are provided on the circumferential surface of a slowly rotating inclined disc.

[Problem that the invention aims to solve]

However, pump type caps 6 and the like shown in FIG. 16 cannot be aligned by the method shown in FIGS. 14 and 15.

That is, the type of cap 6 shown in FIG.
Compared to the trigger type cap 6 shown in Figures 14 and 15, the center of gravity is located closer to the pipe side (opposite the discharge port), so the trigger type caps shown in Figures 14 and 15 are aligned and supplied. Even if you try to align the caps 6 shown in FIG. 16 using the method shown in FIG.
The probability that the caps 6 will align in an inverted manner during rotation is low, and a large amount of unaligned caps 6 will remain. Therefore, it is necessary to remove these unaligned caps 6 before transferring to the next process such as the capping process, and as a result, the alignment ability has to be reduced.

Furthermore, in the conventional technology disclosed in Japanese Utility Model Application Publication No. 59-88020, the discharge nozzle 6 as shown in FIG.
The cap 6 from which 5 protrudes in the radial direction is connected to the nozzle 6.
Because 5 stands out, it cannot be lined up.

[Means for solving problems]

The present invention provides a camp alignment method in which a cylinder with a diameter smaller than that of the cap body is coaxially vertically disposed on a cap body, in which a feeder disk and a cylindrical wall disposed on the outer periphery of the feeder disk are arranged vertically. A gap smaller than the outer diameter of the cap body and larger than the outer diameter of the cylinder is provided in between, and by rotating the feeder disk, a camp is created between the outer circumference of the feeder disk and the cylindrical wall. The above-mentioned problems are solved by providing a method of arranging caps that is characterized by hanging and arranging caps.
