である。[Detailed Description of the Invention] [Technical Field] The present invention is a method for applying a thickening agent such as a sealant or caulking agent to the gap between joints etc. by extruding it according to the width of the joint for purposes such as waterproofing and heat insulation. This relates to a thickener extruder.

しにくく大きな押出力を必要とする。Conventionally, an extrusion rod is driven to push out thickeners such as caulking agents and sealants from the thickener storage chamber to apply them to joints on the exterior walls of prefabricated houses, joints of non-combustible exterior materials, around roofs, around pass-uni7), etc. For example, a thickener extruder for applying around water, window panels, etc.
This is known from the publication No. 1, but since the extrusion rod is manually driven, the hands are very tired, and
There was a drawback that the extrusion speed of the thickening agent was not stable, and as a result, the thickness of the thickening agent was not stable and the finish was poor. In order to solve this drawback, a thickener extruder that drives an extruder rod using a motor housed in a casing to push out the thickener from all the thickener storage chambers was proposed, for example, in Japanese Utility Model Application Publication No. 58-45851. ing. However, commercially available thickeners include silicone-based, modified silicone-based, polyurethane-based, butyl rubber-based, acrylic-based, and oil-based thickeners, each having a different viscosity. Generally silicon-based, modified silicon-based,
Acrylic type has low viscosity and is relatively easy to extrude, but
Butyl rubber and polyurethane materials are difficult to extrude due to their high viscosity and require a large extrusion force.

ある。In addition, the viscosity of these materials also changes depending on the temperature, and polyurethane-based materials in particular have a high temperature dependence and require a large extrusion force as the temperature decreases. In addition, thickeners are used for exterior wall joints of prefabricated houses, joints of non-combustible exterior materials, around roofs,
Water areas such as bath units and window salvage areas are quiet, and the joint width varies depending on the purpose, so when working with a thickener stored in a cartridge type container, it is necessary to use a thickener. The work is carried out by cutting the nozzle tips of the containers in which they are housed to match the width of each joint. The cut inner diameter d (hereinafter referred to as the cutting diameter) of this nozzle is generally 8 mm for the exterior of prefabricated houses such as joints on the exterior walls, and 3 mm for the interior of water areas such as units. The extrusion force required to extrude the thickening agent, which is small as a millimeter, is affected by the cutting diameter d of the nozzle μ, and the smaller the nozzle cutting diameter d, the more difficult it becomes to extrude the thickening agent.

。In this way, the material of the thickener and the cutting diameter of the container nozzle differ depending on the application, and the viscosity of the thickener also varies depending on the season. When applying a thickening agent to the joint, if the viscosity of the thickening agent is low or the cutting diameter of the container nozzle is small, the thickening agent will be extruded at a high speed and the thickening agent extruder will be moved along the joint to work. If the working speed is faster than the extrusion speed of the thickener, there is a disadvantage that the work cannot follow the extrusion speed of the thickener, making it difficult to use. If it is too large, the thickener is extruded at a slow speed and must be stopped at a fixed position between all the joints of the thickener extruder, resulting in poor workability. In order to solve this drawback, it is better to provide a speed variable means to vary the speed of the motor, but if the amount of change in the motor speed with respect to the amount of operation of the operator of the speed variable means is Thickener extruders equipped with speed variable means having linear characteristics have the disadvantage of being difficult to use.
The drawbacks will be explained below with reference to FIGS. 2 and 8 to 10. In order for the speed variable means (a) to have linear characteristics, for example, as shown in FIG.
It is sufficient to adopt a variable resistor with a uniform width By of (b), but if this speed variable means (a) is incorporated into a thickener extruder and the thickener 19 is extruded, the speed variable means (a) Controls (
The relationship between the operation amount in c) and the discharge speed V+ of the thickening agent 19 from the tip of the scum/l/21 is shown in FIG. In FIG. 9, the cutting diameter d of the nozzle A/21 is used as a parameter, the horizontal axis represents the operation amount of the operator (c) of the full speed variable means ((a)), and the vertical axis represents the amount of viscosity agent 19 from the tip of the nozzle 1v21. Discharge speed vI
Assuming that the discharge speed for the thickening agent suitable for thickening work is Vlt-50 mm M seconds to 150 mm/second, the speed variable means (A) must be operated when the cutting diameter d of the nozzle is large, 8 mm, as shown by the dashed line. It is possible to adjust the discharge speed to the appropriate discharge speed for the work over a wide range of operation amount of the child (c). This results in a disadvantage that the operation amount of the child (C) is difficult to adjust because it is narrow from scale to scale, making it difficult to use. Operation amount of the operator (c) of the speed variable means (c) and the discharge speed of the thickening agent 19 ■1
The reason why the above disadvantage occurs when the speed variable means (a) having a linear relationship with is used will be explained. As the cross-sectional diameter d of the nozzle It/21 in a cartridge-type thickener container becomes smaller, the pushing force P required to push out the thickener increases, but the power of the motor 2 becomes smaller than P. The volume q of the thickening agent 19 in the vicinity of the extrusion rod 3 that is pushed out in one second by the extrusion rod 3 moving at the speed V under the condition that the extrusion force P is sufficiently large and the container magazine does not expand due to the extrusion force P is equal to the nozzle IL.
It is the same as the volume Q1 of the thickening agent 19 discharged from the tip of v21 at a speed of 1, and if the inner diameter of the container slide is D and the cut diameter of the cut nozzle v21 is d, then nozzle 1
Discharge speed of thickener 19 from the tip of v21 V+ 9V+
= (” )” V = (4)” D' V,
The discharge speed V+ is directly proportional to the speed of the extrusion rod 3 and °
, is inversely proportional to the square of the cutting diameter d of the nozzle A/21. While keeping the speed V of the extrusion rod 3 constant, the inner diameter d of the nozzle/I/4 is
The discharge speed Vs from the tip of the nozzle/l/21 when changed at a rate of 2 kd becomes V*=-L V +.

This shows the relationship between the discharge speed V+ and the motor 2
2 is a diagram in which the power is large and the load characteristics of the motor 2 are ignored. As shown in Fig. 10, the cutting diameter d of the nozzle/I/4
The relationship between and the discharge speed v of the thickening agent 19 is as follows: When the cutting diameter d is in a large range of 5 mm to 13 mm, the ratio of the change a in the cut diameter d to 2 to the change in the discharge speed Vl is ΔV= is small, but as the cutting diameter d becomes smaller than 4 mm, the slope increases rapidly.
The relationship between the amount of change M in and the amount of change ΔV in the ejection speed V+ is theoretically not a linear relationship but inversely proportional to the square of ~. In a thickener extruder equipped with a speed variable means (B) having linear characteristics, the speed of the motor 2 is changed by operating the operator (C) of the speed variable means (A), and the speed of the extrusion rod 3 is changed. However, the relationship between the amount of change △d in the cutting diameter d of the nozzle 1v21 and the amount of change △V in the discharge speed V+ for the thickener is Since it is inversely proportional to the square of the amount of change △d in the cutting diameter d of /L/21, the cutting diameter d of nozzle A/21 changes in a square relationship in a small range of cutting diameter d of nozzle /l/21.
The amount of change △d and the amount of change △V in the discharge speed V+ of the thickener 19
It was not suitable for the work as shown in the ninth factor. The operating range of the operator (c) that can obtain the discharge speed V+ of the thickening agent 19 becomes smaller.

良い。The diagram ■ shows that when the cutting diameter d of the nozzle/I/21 is 3 mm, the discharge speed V+ of the thickener east is 50 mm ~
This figure shows the relationship between the cutting diameter d of the nozzle B and the discharge speed v1 of the thickening agent 19 at the speed V of the extrusion rod 3. To explain that the cutting diameter d of the nozzle 1v21 is 13 mm in total, the width of the joint width Fi 8 mm to 13 mm/L/(standard 8 mm/I/) for exterior walls such as the joints on the exterior walls of prefabricated houses, and commercially available carts. Ridge type thickener 19 nozzle/%/2
Judging from the size of 1, the nozzle is up to 13 mm/
The cutting diameter d of v21 is set. In addition, the joint width for interior parts around water such as pass units is 2 mm to 3 mm.

is set. Discharge speed v of thickener 19 suitable for work
To explain why I is made to be 50 mm or 150 mm wide, there is a limit to the speed at which the thickener extruder can be moved along the joint.
It was estimated that the leakage was 50 mm, and the speed suitable for the work was set from 50 mm to 150 mm by actually observing the work site. No/I

/second, and the speed of the extrusion rod 3, which makes the discharge speed Vl of the thickener 19 50 mm when the cutting diameter d of the nozzle /v21 is 3 mm. By making the speed of the push rod 3 variable, it is possible to provide a thickener extruder that can be adapted to any type of work. When the cutting diameter d of the nozzle /l/21 is 13 mm, the discharge speed V+ of the thickening agent m is 150 mm.If the speed V of the extrusion rod 3 is 1, then the cutting diameter d of the nozzle Iv21 is 3 mm. When the discharge speed V+ of the thickening agent 19 becomes 50 mm, the speed of the extrusion rod 3 becomes 1 times. Converting this to the speed of the extrusion rod 3, the inner diameter of the container of the commercially available cartridge type thickener 19 is approximately 47 mm, so
V+ = (D-)" When the cutting diameter d' of the nozzle 4 is set to 13 mm or more, the extrusion rod 3's speed V is such that the thickener 19 is discharged by 150 mm. The speed of the extrusion rod 3 becomes 11.4 mm to 0.2 mm!)/
The conditions of the speed variable means 9 may be set so that the speed can be varied within the range of water flow. The diagram ■ in FIG. 6 is a calculation of the cutting diameter d of the nozzle ■ and the discharge speed Vz of the thickening agent 19 when the speed V of the extrusion rod 3 is one times that of the diagram ■. Comparing with the diagram ■ where 1 g of thickening agent was actually extruded using a 1 mm layer at the speed V of 3,
When the cutting diameter d of the nozzle A/21 is 4 mm or more, the viscous first edition is extruded smoothly, and the diagram ■ is similar to the diagram ■. Although the speed variable means 9 has been explained using a variable resistor as an example, the operator for varying the speed of a continuously variable transmission using a conical pulley may be an eccentric cam whose radius gradually increases. It may also be operated. Further, although only one variable resistor is provided as the speed variable means 9, a second variable resistor may be provided in series with the first variable resistor in the number adjustment loop.

This will be explained with reference to FIG. power switch 16
When is operated, the motor 2 is rotated and the push rod 3 is driven. When the operator 10 of the speed variable means 9 is operated, the sliding contact 11 slides on the resistor n, and current flows from the storage battery 4 to the motor 2 according to the resistance between the first terminal port and the sliding contact U. , and the speed of the motor 2 can be made variable.As shown in FIG. Therefore, in the range where the resistance value is large and the speed of the motor 2 is slow, the ratio of the amount of change in the resistance value to the amount of operation of the operator XO is small, as shown in Figure 10. As shown, the thickening agent discharge speed v1 changes greatly depending on the amount of change in the cutting diameter d of the nozzle/v21. When working with a small cutting diameter d of the nozzle/l/21, set it in a state with a large resistance value. Therefore, as shown by the solid line in FIG. 7, the amount of change in the thickening agent discharge speed relative to the operation amount of the operator 10 of the speed variable means 9 can be made small and finely adjusted. In the range where the resistance value of the speed variable means is small and the speed of the motor 2 is high, as shown in FIG.
Although the ratio of the amount of change in resistance value to the operation amount of 0 is large, since the discharge speed V+ of the thickener 19 is set to the fast side, fine adjustment of the discharge speed V+ of the thickeners is necessary. As shown in Figure 10, nozzle A is not required.
When the cutting diameter d of /21 becomes 5 mm or more, the amount of change in the discharge speed V+ of the thickening agent 19 with respect to the amount of change in the cutting diameter d of the nozzle 1v21 is small, so the speed can be varied with linear characteristics without being greatly affected. It is possible to adjust the discharge speed (1) of the thickening agent W to the same extent as in the case of the variable speed means 9 as shown by the dashed line in FIG. The discharge speed of the thickening agent 19 can be adjusted to a speed suitable for the V+ii operation over the entire range of the operation amount of the operator W.

良いという効果がある。As described above, the thickener extruder according to the present invention houses a motor in a casing, connects an extrusion rod for pushing out a thickener such as a caulking agent or a sealant to this motor, and makes the speed of the motor variable. In the thickener extruder, the casing is equipped with an operator for a speed variable means,
Since the speed variable means is characterized by having a parabolic nonlinear characteristic in which the amount of change in speed with respect to the amount of operation of the operator gradually increases, the amount of change in the cutting diameter of the thickener nozzle Even when working with a small cutting diameter of the nozzle, where the discharging speed of the thickening agent changes greatly depending on the operation, fine adjustment is possible by reducing the amount of change in the discharging speed of the thickening agent relative to the operation amount of the operator of the speed variable means. This has the effect of being easy to use.
