Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method of attaching a dispenser to the neck of a container containing a liquid.

``Prior Art'' Many products are manufactured in which a dispenser is attached to the mouth tube of a weir container that stores liquid, and the liquid is poured out from the nozzle tube of an operating body by pushing down the dispenser.

In this type of product, the tip of the nozzle tube that pours out the liquid opens downward, and during the pouring operation, a designated container or arm is held out below the nozzle tube to receive the liquid. Therefore, the tip of the nozzle tube must protrude to the side of the weir container so that the weir container does not get in the way at this time.

However, if the nozzle tube protrudes to the side of the weir container like this, the nozzle tube gets in the way when not in use and becomes inconvenient to handle, so the operating body must be rotated when not in use. , it has been considered to take a position in which the nozzle tube extends in a predetermined direction.

Incidentally, a dispenser has a configuration in which an operating body having a nozzle tube projecting laterally is attached to a cap so as to be mutually rotatable, and this cap is screwed and tightened to the mouth tube of an increase container containing a liquid. Therefore, when the cap is screwed on, the direction in which the nozzle tube projects with respect to the expansion container becomes irregular, so that in some cases, the nozzle tube becomes an obstacle during transportation after injection of liquid.

"Problems to be Solved by the Invention" The present invention aims to solve the above-mentioned conventional drawbacks and inconveniences.
An invented method for attaching a dispenser, which achieves attachment of the dispenser easily and reliably, and
The purpose is to assemble the nozzle tube in a constant posture with respect to the expansion container in a predetermined direction.

"Means for Solving the Problems" In the mounting method of the present invention, first, the dispenser 1, which is the object of the mounting method, is manufactured by penetrating the operating body 2 having the nozzle tube 3 projecting laterally through the cap 6 and mutually attaching the dispenser 1 to the dispenser 1. The cap 6 is screwed and assembled to the opening tube 8 of the volume expansion container 7 in a rotatably assembled configuration.

The means for screwing and assembling the cap 6 onto the mouthpiece 8 is as follows.

First, the cap 6 of the dispenser 1 is temporarily attached to the mouth tube 8 of the weight gain container 7 with the nozzle tube 3 positioned in a substantially constant direction, and the weight gain container 7 is placed in a predetermined position in this state. Retained.

Then, the original body 2 is held between a pair of clamp fingers 22.
After the cap 6 is clamped from the sides by the cap 6, the cap 6 is screwed and tightened onto the opening tube 8 of the weight gain container 7 by a rubber roller 26 which rotates while coming into elastic contact with the circumferential surface of the cap 6 from the side.

"Function" In the above-described configuration, the operating body 2 and the cap 6 of the dispenser l are mutually rotatable, and the operating body 2 is first clamped from the side by the pair of clamp fingers 22 and 24. The nozzle tube 3 is held in a state in which it is temporarily assembled to the mouth tube 8 and extends in a desired direction.

Then, in this posture of the nozzle tube 3, the cap 6 is screwed and assembled to the mouth tube 8 of the expansion container 7 by the rubber roller 26, so when the cap 6 is screwed and fixed, the nozzle tube 3
is maintained in a position extending in the desired direction, and therefore, the extending direction of the nozzle tube 3 in each weight-increasing container 7 to which the dispenser 1 is attached is always constant and regular.

``Example'' First, the operating body 2 of the dispenser 1 has a nozzle cylinder 3 that protrudes laterally from the center of a short cylindrical main body 4 with a built-in check valve and a snap finger spring, and also An inhalation tube 5 extending into the bottom of the weight gain container 7 is hung from the center of the main body 4, and is attached to the cap 6 so as to be rotatable with respect to the other.

FIG. 1 shows an embodiment of the mounting device 9 for carrying out the present invention, in which liquid is injected in the previous step and the spout 8
Then, the bulking container 7, which has been temporarily assembled with the cap 6 of the dispenser 1 in a position with the nozzle tube 3 positioned in a substantially constant direction, is transported to a predetermined position of the mounting device 9 and held there.

A pair of rocking bodies 1 are mounted on the support bar 10, which is located directly above the conveyor 34 that conveys the weight gain container 7.
2 is pivotally mounted.

This rocking body 12 has a structure in which a vertical part 14 is connected to the base end of a horizontal part 13 whose tip is located directly above the weight gain container 7, and the pair of rocking bodies 12 are connected to the horizontal part With the tips of the horizontal parts 13 facing each other, the base ends of the racks 13 are pivoted to the support bar IO via the shaft 15, and are connected by meshing fan-shaped rack teeth 16 provided at the ends of the horizontal parts 13. Further, an engagement hole 17 in the shape of a rectangular elongated hole is opened in the vertical portion 14 along the length direction.

Next, below the support bar 10, a guide bar 11 is installed along the support bar 10, and furthermore, at both ends of the guide bar 11, facing directly above the weight gain container 7, A pair of holders I8 are slidably fitted, and the upper part of the holders 18 is provided with the engagement hole 1 of the rocking body 12.
An engagement pin 19 that loosely fits into 7 is provided in a protruding manner.

A first cylinder 20 is connected to one holder 18, and the holder 18 moves forward and backward along the guide bar 11 by the operation of the first cylinder 20.

The engagement pin 19 has a square pin shape that is approximately equal in width to the engagement hole 17, and although it moves up and down within the engagement hole 17 in a predetermined state, it is not rotatable with respect to the holder 18. Therefore, when the swinging body 12 swings and the vertical portion 14 is displaced, the engagement pin 19 rotates while being restricted by the engagement hole 17.

In FIG. 1, the horizontal portions 13 of the pair of rocking bodies 12 are in a continuous posture in almost a straight line, and the pair of holders 18 are positioned directly above the weight gain container 7 and face each other at a predetermined interval. .

In this state, when the first cylinder 20 is operated and one holder 18 is slid in the direction of the other holder 18,
The vertical portion 14 of one of the rocking bodies 12, which is pivotally connected to one of the holding bodies 18, is pushed by the engagement pin 19 and swings, and the horizontal portion 13 swings upward. In this case, since the engagement hole 17 is in the shape of a square elongated hole and the engagement pin 19 is in the shape of a square bottle, the pressing by the engagement pin 19 is reliable and smooth.

On the other hand, the tip of the horizontal section 13 of the other oscillating body 12 is connected to the tip of the horizontal section 13 of one oscillating body 12 through the meshing of the fan-shaped rack teeth 16 as described above. The horizontal portion 13 also swings upward, and the engagement pin 1
The other holding body 18 slides in the direction of one holding body 18 via the holding body 9 .

Now, on the mutually opposing surfaces of the pair of holders,
A first clamp finger 22 and a second clamp finger 24 are mounted facing each other.

The lower ends of each of these clamp fingers 22, 24 are opposed to each other across the main body 4 of the dispenser +-1, and a clamping notch 2 is formed on the opposing surface corresponding to the curvature of the outer periphery of the main body 4.
3 is provided.

The first clamp finger 22 is connected to the one holding body 1
A second cylinder 21 is attached to the tips of two working rods 22a that slide through the working loft 22a, and a second cylinder 21 is connected to the base end of the working loft 22a.
2 moves forward and backward while maintaining a vertical posture through the operation of the first cylinder 20.

On the other hand, the second clamp finger 24 has an upper end pivotally attached to the opposing surface of the other holder 18 and is swingable in the direction of the other holder 18, and a lower end. A rather strong elastic spring 25 is connected between the other holding body I8.
Therefore, the lower end of the second clamp finger 24 is always urged toward one of the holders 18 by the elasticity of the elastic spring 25.

Next, a rubber roller 26 is provided at the lower end of the holder 18 so as to face the cap 6 of the dispenser 1. In the illustrated embodiment, four rubber rollers 26 are provided, two for each holder 18, and rotate in one predetermined direction in conjunction with each other.

Figure 5.6 shows the transport line for the weight gain container 7, and the weight gain container 7 filled with liquid is transported to the dispenser 1.
are temporarily assembled and conveyed by the conveyor 34, but at a position above the conveyor 34 immediately before the mounting device 9, corresponding to the upper part of the dispenser 1 of the increase container 7,
Guide plate 3 whose tip opens toward the upstream side of the line
8 is constructed along the line.

As the weight gain container 7 moves as the con hair 34 travels, the nozzle 3 protruding in irregular directions of the temporarily assembled dispenser 1 is forcibly rotated by the tip of the guide plate 38. It assumes a posture extending in the direction along the line of the conveyor 34.

The expansion container 7 sent directly below the mounting device 9 in this posture is
It is stopped by a first stopper 35 that protrudes at right angles to the conveyor 34, and when this stop is sensed, a second stopper 36 protrudes, thereby being held directly below the mounting device 9.

Note that the upper and lower parts on both sides of the conveyor 34 are
A support plate 37 is provided along the line.

Now, when the weight gain container 7 is positioned directly below the attachment device 9 and held, the first clamp finger 22 is moved forward by the forward motion of the second cylinder 21, and the outer periphery of the main body 4 of the dispenser 1 is moved forward. The clamping notch 23 is fitted in and strongly abuts against the outer periphery of the main body portion 4.

Next, when the first cylinder 20 is operated a little later than the forward movement of the second cylinder 21, one holder 18 slides in the direction of the other holder 18, as described above, and one of the swinging bodies 12 is oscillatingly displaced, and along with this,
The tip of the horizontal part 13 of one rocking body 12 and the fan-shaped rack teeth 16
As the other linked rocking body 12 is rocked and displaced by the engagement of the two, the other holding body 18 also slides in the direction of the one holding body 18.

As a result, the second clamp finger 24 receives the elasticity of the elastic spring 25 while the clamping notch 23
fits into the outer periphery of the main body 4 of the dispenser 1, and maintains the predetermined posture in which the main body 4 of the dispenser 1 together with the first clamp finger 22 extends in the direction along the line of the conveyor 34 of the nozzle cylinder 3. However, it is strongly held from both sides.

Further, as the pair of holders 18 move forward in the direction toward each other, each rubber roller 26 comes into elastic contact with the outer peripheral surface of the cap 6, and due to the rotation of the rubber roller 26, the cap 6
It is strongly screwed and tightened to the mouth tube 8 of the weight gain container 7.

Various means for rotating the rubber roller 26 can be considered, and one example thereof is shown in FIGS. 3 and 4.

Here, driven gears 29 are fixed at predetermined positions on the shafts of two rubber rollers 26 of one holder 18, and the rotation of a driving gear 28 that is positioned between and meshes with both driven gears 29 is transmitted.

Further, one of the two rubber rollers 26 of the other holding body 18 has a driven gear 29 fixed thereto, and the rotation of the drive gear 28 is transmitted via a belt 31, and the other one is free. It comes into contact with the outer circumferential surface of the cap 6 in this state.

By the way, since the pair of holders 18 move toward and away from each other as described above, the belt 31
It must be able to expand and contract while maintaining a predetermined tension. In the illustrated embodiment, the belt 31 is hooked onto a tension roller 32 of a tension body 33, and the heald 31 is tensioned by the tensile force of the tension body 33.

In addition, various forms of the notch end surfaces of the clamping notches 23 of the first clamp finger 22 and the second clamp finger 24 are conceivable.

In Fig. 7, in a, a cushioning material 23a such as urethane rubber is attached to the end face of the notch to protect the outer peripheral surface of the main body 4 of the dispenser 1, which is strongly held, and in b, the notch A vertical strip 23b is carved into the end face in a low left shape to prevent the main body 4 from slipping when clamped, and in addition, in C, a protrusion 23c in the shape of letters such as alphabets is formed on the notched end face. It is provided so that it can be engraved on the outer peripheral surface of the main body part 4 when it is strongly clamped.

"Effects of the Invention" As is clear from the above explanation, the dispenser mounting method of the present invention allows the dispenser 1, in which the operating body 2 and the cap 6 are mutually rotatable, to
First, the operating body 2 is clamped from the sides by the pair of clamp fingers 22, 24, so that the nozzle tube 3 can be extended in the desired direction in the state temporarily assembled to the mouth tube 8. Since the cap 6 is held in the extended position and then screwed onto the spout 8 by the rubber roller 26, the extending direction of the nozzle cylinder 3 in each bulking container 7 to which the dispenser 1 is attached is as follows.
It is always constant and regular, and the nozzle tube 3 does not get in the way when the weight gain container 7 is being transported.

Therefore, according to the present invention, the dispenser 1 can be easily and reliably attached, the nozzle tube 3 can be extended in a predetermined direction with respect to the expansion container 7, and handling is convenient. It has many excellent functions and effects, such as a simple configuration.
