High-viscosity liquid filling system suitable for
[0002]
[Prior art]
As a sealing material filling container filled with a sealing material for building, as shown in a filling container 100 shown in FIG. 19, a discharge port 102 for discharging a sealing material 101 is formed at a distal end portion, and a hard opening having a base end portion opened. The one having a cylindrical container main body 103 and a plunger 104 fitted inside the base end opening of the container main body 103 is widely used. In the filling container 100, a sealing lid 105 for sealing the discharge port 102 is opened, and then the virgin film 106 is cut. Then, a nozzle (not shown) is attached to the discharge port 102, and this is set to a dedicated discharge gun. The sealing material 101 can be extruded and discharged by sequentially moving the plunger 104 toward the inner end of the container body 103 by operating the lever of the discharge gun.
[0003]
By the way, as a method of filling the sealing material 101 into the container body 103 of this type, the container body 103 is normally held in a vertical position with the base end facing upward, and in this state, air bubbles do not enter from the base opening. Is filled with a certain amount of the sealing material 101, and then, while the plunger 104 is inserted into the container body 103, the air between the plunger 104 and the sealing material 101 is forcibly forced from the sliding portion between the plunger 104 and the container body 103. In this case, a method is employed in which the air is discharged to the outside and inserted so that air does not remain in the sealing material 101.
[0004]
In the filling container 100 having such a configuration, the air between the plunger 104 and the sealing material 101 can be almost completely discharged to the outside, and the airtightness between the plunger 104 and the container body 103 can be sufficiently ensured. Therefore, although it is widely used at present, since the container main body 103 is hard, the filling container 100 cannot be crushed to a small size after use, and there is a problem that the volume reduction is limited and the waste is bulky.
[0005]
Therefore, as described in JP-A-7-171461, the intermediate body of the container body is made of a soft film material, and the upper and lower molding portions, which are relatively hard, are formed at the distal end and the proximal end of the container main body. A filling container in which a part is integrally formed has also been proposed. In this filling container, this is loaded into the outer cylinder of the discharge gun and the lower molded part is moved to the upper molded part side, so that the sealing material is extruded from the discharge port formed in the upper molded part while the intermediate body part is crushed. Since the liquid is discharged, the used filling container is in a small crushed state, and the volume of waste can be reduced.
Also, this publication discloses a filling method of filling a sealing material into a container body from an opening of a lower molding portion formed in a ring shape, and closing the opening in an airtight manner after the filling as a filling method of the sealing material. Has been described.
[0006]
[Problems to be solved by the invention]
By the way, in the case of the rigid cylindrical container body 103 as in the above-described filling container 100, the container body can be positioned and set on a conveyor orthogonally to the conveying direction, and can be transferred from the molding apparatus to the filling apparatus. As described in the above, a soft container body such as an intermediate body made of a soft film material, when conveyed by the same conveyance device, may be deformed at the time of conveyance, such a container body efficiently There is a need for a transport system that can be transported.
[0007]
On the other hand, in the filling container described in the above publication, since the sealing material is discharged while crushing the container body, the volume of the used container can be reduced, but there are the following problems.
That is, in order to improve the airtightness between the lower molded portion and the lid member, the lid member and the lower molded portion can be airtightly fitted and fixed, for example, via an annular concave / convex fitting portion. With this configuration, since the mounting position of the lid member with respect to the lower molded portion is fixedly set, if the injection amount of the sealing material into the container body is not set accurately, if the injection amount is small, the filling container When the sealing material is hardened in the filling container due to the air remaining therein and the injection amount is large, a problem occurs that the sealing material overflows to the outside when the lid member is plugged. In addition, even when the container is filled with high accuracy, the air between the container body and the lid member needs to be completely exhausted when the lid member is fitted in the container body in an airtight manner, and thus no air remains. Thus, it is difficult to fit and attach the lid member.
[0008]
The inventor of the present invention has set that when the injection amount of the sealing material into the container body is set to be relatively large, although the excess sealing material overflows to the outside, the air between the container body and the lid member is almost completely discharged. Paying attention, with the sealing material injected into the container body, press the middle part in the length direction to raise the liquid level of the sealing material with respect to the container body, and increase the apparent injection amount of the sealing material It has been found that by setting to, the air between the container body and the lid member is almost completely discharged when the lid member is inserted and mounted.
[0009]
An object of the present invention is to effectively prevent deformation and the like in the middle of transport, and furthermore, while using a transport system of a cylindrical member capable of improving transport efficiency, and a container main body having at least a body portion formed of a flexible film body, An object of the present invention is to provide a filling system for a highly viscous liquid which can effectively prevent air from remaining when the highly viscous liquid is filled.

Although the injection device is not shown, the high-viscosity liquid injection pipe 71 (see FIG. 15A) disposed above the container main body 2 transferred by the rotary table 67, and the container main body 2 together with the clamper 65 Elevating means for elevating and lowering along the guide rod 69, in which the container body 2 is raised by the elevating means and the high-viscosity liquid injection pipe 71 is inserted into the inner part of the container body 2, and the high-viscosity liquid injection is performed. The container body 2 is lowered while discharging the high-viscosity liquid 4 from the pipe 71, and the high-viscosity liquid 4 can be injected into the container body 2 so that air bubbles do not enter. However, if the elevating means is configured so that the high-viscosity liquid injection pipe 71 can be moved up and down relatively to the container main body 2, the container main body 2 is fixed and the high-viscosity liquid injection pipe 71 is moved up and down. And the high viscosity liquid injection pipe 71 and the container body 2 may be moved up and down, respectively.
[0042]
The stopper device 70 will be described. At a position above the clamper 65, a holding portion 73 that holds the lid members 3 sequentially supplied from the lid supply means 72 one by one is provided. A slightly smaller diameter through hole 74 (see FIG. 16) is formed, and the upper inner surface of the through hole 74 is formed in a tapered shape whose diameter is reduced downward. Above the holding portion 73, there is provided a tapping means 75 for plugging the lid member 3 held by the holding portion 73 from the through hole 74 into the reinforcing ring 11 of the container main body 2 disposed therebelow. 3 is supplied to the holding portion 73 by the lid supply means 72 and is plugged into the reinforcing ring 11 of the container body 2 by the head 75a of the plugging means 75.

A push lever 76 is rotatably provided. The push lever 76 is opened and closed by an air cylinder 77 between an open position shown by a solid line in FIG. 14 and a pressed position shown by a virtual line in FIG. However, the pressing lever 76 only needs to be configured to be able to press at least a part of the middle part of the body part 10 in the height direction, so that the number of pressed parts of the body part 10 may be other than two. Then, it may be pressed over the entire circumference. Further, the pressing portion can be formed at any position in the height direction, but it is preferable to press the central portion in consideration of operability. Further, when a plurality of pressing levers 76 are provided, the pressing locations may be shifted in the height direction. Reference numeral 78 denotes a support member that supports the holding claws 66 of the clamper 65 from below, thereby preventing an excessive load from acting on the clamper at the time of plugging.
[0043]
Next, the operation of the filling device 34 will be described while describing a method of filling the high viscosity liquid 4 into the container body 2.
From the delivery device 51 to the filling device 3465Is rotated by 90 ° together with the turntable 67 and transferred to the injection device. Then, as shown in FIGS. 15A and 15B, the container main body 2 is raised together with the clamper 65 by the injection device, and the highly viscous liquid injection pipe 71 is inserted deep into the container main body 2. While the high-viscosity liquid 4 is being injected from the high-viscosity liquid injection pipe 71 in this state, the container body 2 is tuned down together with the clamper 65 so that the high-viscosity liquid 4 does not enter into the container body 2. The required amount of the viscous liquid 4 is injected. When the high-viscosity liquid 4 is injected, the liquid surface of the high-viscosity liquid 4 has a mountain-like shape with a raised central portion because the viscosity of the high-viscosity liquid 4 is high.
Next, the container main body 2 into which the high-viscosity liquid 4 has been injected is rotated 90 ° together with the turntable 67 and transferred to the tapping device 70. Then, as shown in FIGS. 15C and 16, the tapping device 70 presses the middle part of the body 10 of the container body 2 with the pressing lever 76, so that the liquid level of the highly viscous liquid 4 is increased. The apparently high injection amount of the high-viscosity liquid 4 that has been raised is injected is adjusted to be relatively large. At this time, the liquid level of the highly viscous liquid 4 rises while substantially maintaining the mountain shape at the time of injection.

As shown in (d), the sliding cylindrical portion 20 of the lid member 3 is inserted into the reinforcing ring 11 of the container body 2. At this time, the lid member 3 is firstly shown in FIG.UThen, while closely contacting the top of the liquid surface of the high-viscosity liquid 4 and then crushing the top of the liquid surface, that is, while spreading the contact portion between the liquid surface and the lid member 3 toward the outer periphery, the high-viscosity liquid 4 Since the liquid adheres to the liquid surface, the air between the lid member 3 and the highly viscous liquid 4 is discharged.And moreWhen the lid member 3 starts to be inserted into the reinforcing ring 11, the lid member 3 is almost completely discharged to the outside through the gas vent groove 26, and as shown in FIG.ofIt is inserted into the reinforcing ring 1. Incidentally, even if the pressing of the body 10 by the pressing lever 76 is not released, since the body 10 is a flexible film, the cover member 3 is inserted with a force greater than the pressing force of the pressing lever 76, and the plug 3 is plugged. Is also good.
[0045]
At this time, the cap member 3 is pushed into the reinforcing ring 11 by the tapping means 75, and the fitting protrusion 14 of the reinforcing ring 11 in the annular groove 23 of the cover member 3 is fitted as shown in FIG. At the same time, the protrusion 24 of the lid member 3 is fitted into the fitting groove 15 of the reinforcing ring 11, and the lid member 3 is fixed to the reinforcing ring 11 in an airtight manner.
In the high-viscosity liquid filling container 1 in which the high-viscosity liquid 4 is injected into the container body 2 and stoppered in this manner, air can be effectively prevented from remaining near the lid member 3, and the high-viscosity due to the residual air can be prevented. Deterioration and hardening of the liquid preparation 4 can be effectively prevented.
