Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a conveying chute suitable for supplying caps with liquid suction pipes from a feeder to a cap tightening machine or the like.

BACKGROUND TECHNOLOGY In recent years, caps for liquid containers that have accessories such as spouts that are screwed in and out from the outside of the cap body that screws into the opening of the container, and have a suction pipe inside are often used. . For example, it can be used as a cap for containers such as liquid detergent or shampoo.
A cap with a liquid suction pipe as shown in the figure is known. The cap 15 has a liquid suction pump cylinder 17 inside a cap body 16, which has a screw on its inner surface that engages with a screw on the outer circumference of the opening of the container, and a piston rod 19 of the pump.
(Figure 1) is a pipe that guides the liquid,
Extending from above the cap body, there is a pressing part 2 at the top of the cap body.
0, and a liquid spout 21 is attached to the pressing portion. A liquid suction pipe 23 is provided at the bottom of the cylinder 17 and extends to near the bottom of the container. In order to fix the piston rod 19, which is always urged to protrude, in the lower part of the pressing part 20 while being pushed into the cylinder,
A thread is provided which threads into the cylinder head 18 of the pump. As a result, the piston rod 19 is always kept pushed into the cylinder, and when in use, by rotating the pressing part and unscrewing it from the cylinder head, the piston rod protrudes from the cylinder and the pressing part is pushed up. By sucking up the liquid inside,
It can be poured from the spout.

Conventionally, the caps are supplied to the cap tightening machine by conveying them through a wire chute 25 made up of a plurality of round wires as shown in FIGS. 6 and 7 using a vibrating feeder or the like. The wire chute supports the bottom of the cap main body with bottom guides 29 and 30, and is guided by side guides 27 and 28 and a top pressing guide 26, so that the cap main body is suspended and conveyed downward. There is.

Problems to be Solved by the Invention The above-mentioned cap is normally transported on the chute with the piston rod pushed in, but sometimes the screw may become loose and the cap may be transported with the piston rod protruding. In such a case, in the conventional wire chute, the top surface of the cap pressing portion would hit the chute's top surface pressing guide, causing the flow to stop. In order to solve this problem, it is conceivable to eliminate the chute's top presser guide, but if the top presser guide is removed, the cap 15 transported in a suspended state will swing back and forth and from side to side, causing the front and rear caps to sway. A problem arises in that spouting ports or liquid suction pipes become entangled with each other and the flow is obstructed.

In addition, in conventional models, the lower surface of the cap body is supported and the cap is transported in a suspended state, so the lower flat surface of the cap body and the round bar of the chute do not easily slip, making it difficult to move smoothly. .

The present invention was devised in order to solve the above-mentioned drawbacks of the prior art, and it does not cause clogging even if the accessory having the liquid spout protrudes from the top surface of the cap during transportation, and also allows the cap and chute surface to be connected. The purpose of the present invention is to provide a cap transport chute with a liquid suction pipe that has good sliding properties and can smoothly transport the caps.

Means for Solving the Problems The configuration of the present invention for solving the above problems will be explained using FIG. 1, which corresponds to an embodiment.

The conveyance chute 1 of the present invention has a movable protruding attachment with a liquid spout attached to the outer top surface of the cap main body that engages with the container opening, and a cap having a liquid suction pipe inside can be placed sideways. The chute is a conveyor chute that allows the cap body to flow down in a state, and includes a cap body guide groove 2 having a rectangular cross section in which the cap body is fitted and slidably guided, and a smooth outer guide surface 3 formed on both sides of the guide groove 2. The device has an inner guide surface 4, and the outer guide surface 3 is formed with a width within a range that does not allow the side surface of the outer guide surface 3 to come into contact with the liquid spout 23 of the cap being transported.

Function When the cap 15 is placed on its side, the cap body 16
While being guided by the cap main body guide groove 2, the cap body slides on the sliding surface on the bottom of the guide groove, or a part of the protruding parts on both sides of the cap main body slides on the inner sliding surface 3 and the outer sliding surface 4 and flows down. The width of the cap body guide groove is formed to be approximately the same as the height of the cap body, so when the cap body engages with the groove 2, the inside and outside of the cap body are aligned with both side walls of the guide groove. The cap does not sway from side to side during the flow, and the cap always flows down with its axis intersecting the chute axis at right angles. Therefore, the pouring ports or the suction pipes do not become entangled with each other while flowing down, and the fluid flows down smoothly. Furthermore, even if the spout attachment of the cap protrudes during the flow, there is nothing to restrain the spout attachment, so the flow will not be obstructed. Furthermore, since the cap body is usually rotatably attached to the cylinder, when the cap body comes into contact with the bottom surface of the guide groove and flows down, it comes into rolling contact and flows down smoothly.

Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 shows an embodiment of the chute of the present invention. The chute 1 allows a cap 15 with a liquid suction pipe to flow down in a straight line in a horizontal state, and is formed with a cap main body guide groove 2 having a rectangular cross section that fits and slides the cap main body 16. Both sides are smooth sliding surfaces 3 and 4 having appropriate widths. The width of the cap body guide groove 2 is slightly wider than the height of the cap body 16 to provide play so that the cap can slide smoothly. The width of the outer sliding surface 3 on which the outer side of the cap body 2 is located is such that even if the cap body 16 engaged with the guide groove 2 moves outward by the amount of play, the cap spout 21
is determined within a range that does not hit the side of the chute.
Further, the inner sliding surface 4 is configured to have an appropriate width so as to guide the cylinder portion 17 of the pump.

The chute 1 of this embodiment is constructed as described above, and since the inside and outside of the cap body are restrained by both side walls of the guide groove, the cap does not swing from side to side while flowing down, and its axis is always maintained. Flows down perpendicular to the chute axis. Furthermore, even if the piston rod 19 of the cap during the flow protrudes as shown by a in FIG. 1, there is nothing to restrain the pressing portion 20, so the flow will not be hindered.

2 to 4, a cap with a suction pipe that is continuously pushed out from the feeder 10 shown in FIG. This is an embodiment in which the present invention is applied to a spiral chute section 12. The spiral chute portion is composed of a substantially linear chute and a curved chute arranged in a connected manner so as to descend in a spiral manner along the pillar 7, and these chute are supported on the pillar 7 by a bracket 9. are doing.

In this embodiment, as shown in FIGS. 2 and 3, straight chute 5, 5' and curved chute 6, 6' having the same cross-sectional shape as in the previous embodiment are vertically opposed to each other to form a cap. The caps are arranged at intervals that allow the caps to pass through, so that the caps will not jump out even if the caps flow downward in a spiral pattern.

In the above embodiment, a case was explained in which a cap as shown in FIG. It goes without saying that it can be done.

Effects The chute of the present invention is configured as described above,
When the cap is laid on its side, the cap body slides while being guided by the cap guide groove, and the circumference of the cap contacts the sliding surface, making it slide more smoothly than conventional caps that slide with the bottom of the cap in contact. Flow down. In addition, the inside and outside of the cap body are restrained by both side walls of the guide groove, and the cap does not swing from side to side while flowing down. Inside, the pouring ports or suction pipes do not get entangled with each other, and the flow flows smoothly. Furthermore, even if the spout attachment of the flowing cap protrudes,
Since there is nothing to restrict the spout attachment, the flow is not obstructed.
