Description

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

"Prior Art" Many products are manufactured in which a dispenser is attached to the spout of a bottle that stores a liquid, and the liquid is poured out from a 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 is opened toward the bottom, 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 bottle so that the bottle does not get in the way at this time.

However, if the nozzle tube protrudes to the side of the bottle 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 assembled to a cap so as to be mutually rotatable, and the cap is screwed and tightened to the mouth tube of a bottle container containing a liquid. Therefore, when the cap is screwed together, the direction of protrusion of the nozzle tube relative to the bottle container becomes irregular, so in some cases, the nozzle tube may become an obstacle during transportation after injection of liquid. It was hot.

"Problems to be Solved by the Invention" The present invention is a dispenser mounting method devised to solve the above-mentioned conventional drawbacks and inconveniences, and is a dispenser mounting method that easily and reliably achieves the dispenser mounting. The purpose is to assemble the nozzle tube in a constant posture with respect to the bottle container extending 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 installation method is first constructed 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 assembled in a rotatable manner, and is screwed onto the mouthpiece 8 of the bottle container 7.

The means for screwing and assembling the cap 6 to the spout 8 is as follows.

First, the cap 6 of the dispenser 1 is temporarily assembled to the mouthpiece 8 of the bottle container 7 with the nozzle tube 3 positioned in a substantially constant direction, and the bottle container 7 is held in a predetermined position in this state. is maintained.

After the operating body 2 is clamped from the sides by a pair of clamp fingers 22 and 24, the cap 6 is clamped into the opening of the bottle container 7 by a rubber roller 26 which rotates while coming into elastic contact with the peripheral surface of the cap 6 from the side. 8 and tighten it.

"Function" In the above-described configuration, the operating body 2 and the cap 6 of the dispenser 1 are mutually rotatable.
2 and 24 from the sides, 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, with the nozzle tube 3 in this position, the cap 6 is screwed and assembled to the mouth tube 8 of the bottle container 7 by the rubber roller 26, so when the cap 6 is screwed and fixed, the nozzle tube 3 is moved in the desired direction. The extended posture is maintained, and therefore, the extending direction of the nozzle tube 3 in each bottle container 7 to which the dispenser 1 is attached is always constant and regular.

"Example" First, the operating body 2 of the dispenser 1 is a check valve,
A nozzle tube 3 protruding laterally from the center of a short cylindrical body part 4 with a built-in elastic spring etc. is provided in series, and a nozzle tube 3 is provided in a row at the center of the body part 4 and extends into the bottom of the bottle container 7. It has a suction tube 5 hanging down,
They are attached to the cap 6 so as to be rotatable with each other.

FIG. 1 shows a mounting device 9 for implementing the present invention.
This is an example of a bottle in which a liquid has been injected in the previous process, and the cap 6 of the dispenser 1 is temporarily assembled to the spout 8 with the nozzle tube 3 positioned in a substantially constant direction. The container 7 is transported to a predetermined position on this attachment device 9 and held there.

The support bar 10, which is located directly above the conveyor 34 that conveys the bottle container 7, has a
A pair of rocking bodies 12 are pivotally mounted.

This rocking body 12 has a configuration in which a vertical part 14 is connected to the base end of a horizontal part 13 whose tip is located directly above the bottle container 7 in a substantially L-shape.
In this case, the distal ends of the horizontal portions 13 face each other, the proximal ends of the horizontal portions 13 are pivotally connected to the support bar 10 via the shafts 15, and the fan-shaped rack teeth 16 provided at the distal ends of the horizontal portions 13 engage with each other. In addition, an engagement hole 17 in the shape of a square 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 bottle container 7, A pair of holding bodies 1
8 is fitted in a slidable manner, and the holding body 18
An engagement pin 19 that loosely fits into the engagement hole 17 of the rocking body 12 is protruded from the upper part of the swing body 12 .

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

The engaging pins 19 have a rectangular pin shape approximately equal to the width of the engaging hole 17, and move up and down within the engaging hole 17 in a predetermined state, but are rotatable relative to the holding pair 18. Therefore, when the swinging body 12 swings and the vertical portion 14 is displaced, the engagement pin 1
9 can rotate even though it is 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, almost in a straight line, and the pair of holders 18 are positioned directly above the bottle 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 swinging bodies 12, which is pivotally connected to one holder 18, Pushed by the engagement pin 19, 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 pin, the pressing by the engagement pin 19 is reliable and smooth.

On the other hand, the tip of the horizontal part 13 of the other rocking body 12 is
Since the distal end is linked by the meshing of the fan-shaped rack teeth 16, the horizontal part 13 of the other swinging body 12 also swings upward, and the other holding body 18 is moved from one side to the other via the engagement pin 19. It slides in the direction of the holder 18.

Now, a first clamp finger 22 and a second clamp finger 24 are mounted on opposing surfaces of the pair of holders 18, facing each other.

The lower ends of these clamp fingers 22 and 24 are opposed to each other with the main body 4 of the dispenser 1 interposed therebetween, and a clamping notch 23 is provided on the opposing surface corresponding to the curvature of the outer periphery of the main body 4.

The first clamp finger 22 has two working rods 22 that slide through the one holder 18.
A second cylinder 21 is attached to the tip of the working rod 22a, and a second cylinder 21 is connected to the base end of the working rod 22a.
The first clamp finger 22 moves forward and backward while maintaining its vertical position by the operation of the first cylinder 20.

In contrast, 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 between it and the other holder 18. A rather strong elastic spring 25 is disposed, and the elasticity of the elastic spring 25 causes the lower end of the second clamp finger 24 to always touch one of the holders 1.
It is biased in eight directions.

Next, the lower end of the holder 18 has a dispenser 1
A rubber roller 26 is provided opposite the cap 6. 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.

5 and 6 show a conveyance line for the bottle container 7. The bottle container 7 filled with liquid is transferred to the conveyor 3 with the dispenser 1 temporarily assembled.
At a position above the conveyor 34 immediately before the mounting device 9, there is a guide plate 38 whose tip opens toward the upstream side of the line, corresponding to the upper part of the dispenser 1 of the bottle container 7.
It is constructed along the line.

As the bottle container 7 moves as the conveyor 34 travels, the nozzle tube 3 of the temporarily assembled dispenser 1 that protrudes in irregular directions is forcibly rotated by the tip of the guide plate 38. The conveyor 34 is moved to a position extending in the direction along the line of the conveyor 34.

The bottle container 7 sent directly below the mounting device 9 in this attitude is stopped by the first stopper 35 that protrudes in an attitude perpendicular to the conveyor 34, and upon sensing this stop, the second stopper 36 protrudes. As a result, it is held directly below the attachment device 9.

Note that support plates 37 are provided along a line at the upper and lower parts of both sides of the conveyor 34.

Now, when the bottle container 7 is positioned directly below the mounting device 9 and held, the first clamp finger 22 is moved forward by the forward movement of the second cylinder 21, and the main body portion 4 of the dispenser 1 is moved forward. The clamping notch 23 fits into the outer periphery of the body portion 4 and strongly contacts 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 in conjunction with this, the other oscillating body 12, which is connected to the tip of the horizontal portion 13 of one oscillating body 12 through engagement with the fan-shaped rack teeth 16, is oscillatingly displaced, so that the other oscillating body 12 is not held. The body 18 also slides in the direction of one of the holding bodies 18.

As a result, the second clamp finger 24
Although receiving the elasticity of the elastic spring 25, the clamping notch 23 fits into the outer periphery of the main body 4 of the dispenser 1, and the first clamp finger 22
At the same time, the main body portion 4 of the dispenser 1 is strongly held from both sides while maintaining the predetermined posture in which the nozzle tube 3 extends in the direction along the line of the conveyor 34.

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 the rotation of the rubber roller 26 causes the cap 6 to close the opening of the bottle container 7. It is strongly screwed and tightened to the cylinder 8.

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.

In addition, the two rubber rollers 2 of the other holding body 18
Similarly, one of the gears 6 has a driven gear 29 fixed thereto, and the rotation of the drive gear 28 is transmitted through a belt 31, and the other gear is free and comes into contact with the outer peripheral surface of the cap 6.

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

Note that the clamping notches 23 of the first clamp finger 22 and the second clamp finger 24
Various forms of the notch end face can be considered.

In FIG. 7, in a, a cushioning material 23a such as urethane rubber is attached to the notched end surface, and the main body 4 of the dispenser 1 is strongly held.
It protects the outer peripheral surface of the notch, and in b, a knurled vertical strip 23b is carved on the notch end surface.
It is designed to prevent the main body part 4 from slipping when being held.
Further, in c, a protrusion 23c in the shape of a letter such as an alpha alphabet is provided on the end face of the notch, so that it can be engraved on the outer circumferential surface of the main body 4 when it is strongly clamped.

"Effects of the Invention" As is clear from the above explanation, the present invention has the advantage of clamping the cap at the mouth of the container while the operating body with the nozzle tube positioned in a substantially constant direction is immovably clamped between a pair of clamp fingers. Since the dispenser is screwed into the cylinder, the operating body will not be rotated due to the rotation of the cap for screwing, and this will ensure that the dispenser is assembled into the container in the desired position. This can be achieved stably, and the container as a product with the dispenser assembled therein can be transported and handled smoothly and favorably.
