Description

  The present invention relates to a molding apparatus for a viscoelastic resin molded product typified by a styrene elastomer and a method for molding a viscoelastic resin molded product.

As prior art document information related to the molding technology of this type of viscoelastic resin molded product, there is Patent Document 1 shown below.
In Patent Document 1, by using a resin molded body such as a gelatin-like viscoelastic elastomer as a cushioning material to be installed in a bed or sofa, pressure concentration seen with a conventional metal spring is removed, It is described that comfort can be achieved by distributing cushioning effects over a wider surface.

  Further, there is Patent Document 2 shown below as another prior art document information related to the molding technology of this type of viscoelastic resin molded product. In Patent Document 2, the viscoelastic elastomer described in Patent Document 1 is remarkably soft and easily deformed, and because it has adhesiveness, it is difficult to remove the mold with a conventional protruding pin. One way to do this has been proposed. In this method, the production line is divided into a zone in which a viscoelastic resin material of about 120 ° C. is pressed into a cylindrical mold from a kneader, and a zone in which the viscoelastic resin material is kept at a high temperature of 200 ° C. or less while remaining in the cylindrical mold. And a zone in which the viscoelastic resin material is air-cooled to about 100 ° C. while remaining in the cylindrical mold, and finally a zone in which the viscoelastic resin material is removed from the cylindrical mold, and along each of these zones A large number of cylindrical molds are sequentially moved by a conveyor. The reason why the mold is removed after cooling as described above is that when the viscoelastic resin is removed at a high temperature, the shape retention is insufficient and a viscoelastic resin molded product having a desired shape cannot be obtained.

Special table 2001-514912 (page 12, lines 3-20, FIG. 3, FIG. 6) Japanese Patent Laying-Open No. 2005-096239 (paragraph 0039, FIGS. 1 and 7)

  However, in the method for molding a viscoelastic resin molded article described in Patent Document 2, it is necessary to provide a plurality of zones for simultaneously conveying a large number of cylindrical dies, so even if each zone is continuously arranged annularly, Production lines tended to require a large footprint. In addition, in order to increase the production capacity of the production line, it is necessary to increase the number of cylindrical molds, and thus it is necessary to increase the size of each zone. In addition, in order to produce a plurality of types of viscoelastic resin molded products having different shapes such as outer diameter or length, there was a problem that it was necessary to separately prepare a large number of cylindrical dies having different shapes. . Furthermore, since there are basically a plurality of cylindrical molds that are processing viscoelastic resin in each zone, if it is necessary to change the shape of the viscoelastic resin molded product, all the cylindrical molds are replaced. It took a long time for the cylindrical mold in the first press-fitting zone to move sequentially and to receive treatment in the last demolding zone.

  Accordingly, the object of the present invention is to increase the production capacity of the production line by taking up a relatively small area of the production line in view of the problems given by the continuous molding method of viscoelastic resin molded products according to the prior art exemplified above. Another object of the present invention is to provide a molding apparatus and a molding method for a viscoelastic resin molded product that do not require an excessively large occupied area.

  Another object of the present invention is to provide a molding apparatus and a molding method for a viscoelastic resin molded product that requires relatively little equipment when manufacturing a plurality of types of viscoelastic resin molded products having different shapes. There is.

  Another object of the present invention is to provide a viscoelastic resin molded article continuous molding apparatus and a viscoelastic resin molded article continuous molding method in which the shape change of the viscoelastic resin molded article is completed in a relatively short time. .

The characteristic configuration of the continuous molding apparatus of the viscoelastic resin molded product according to the present invention is:
A die portion for extruding a viscoelastic resin material containing a styrene-based elastomer and a paraffin-based process oil into a predetermined cross-sectional shape;
Quantitative conveying device for feeding at a constant speed of the viscoelastic resin material charged toward the die unit,
And a temperature control conveyance unit for conveying the die unit in a sealed state while the temperature adjusts the viscoelastic resin material fed by the quantitative transporting device,
The temperature control conveyor section has a heating temperature control unit for heating by the heating means to the outer peripheral surface disposed on the outer periphery of the temperature control conveyor section of the viscoelastic resin material to be conveyed inside the temperature control conveyor section, wherein have a said heating cold tone portion release disposed on the downstream side of the temperature control unit in order to cool the viscoelastic resin material heated by the heating temperature control unit,
The heating means has the lowest releasability within the range in which the molded product discharged from the die part does not adhere to the inner surface of the die part in a layered manner, the temperature of the viscoelastic resin material at the outer peripheral part in the heating temperature control part Set it to be higher than the minimum temperature,
The cooling temperature adjusting unit is located on the center side in the radial direction of the outlet of the die part, and the viscoelastic resin material located on the outer periphery of the outlet of the die part has a temperature higher than the lower limit temperature of the releasability. The viscoelastic resin material is configured to have a temperature lower than the highest shape retention upper limit temperature within a range in which the cross-sectional shape of the molded product can be maintained,
On the downstream side of the die portion, a cutter device for cutting the viscoelastic resin material extruded from the die portion with a predetermined length is provided .

  In the continuous molding apparatus for a viscoelastic resin molded product having the above-described characteristic configuration, a sealed temperature control conveyance unit is provided between the quantitative conveyance device and the die part, and the temperature control conveyance unit is viscoelastic resin conveyed inside. A special coating treatment is applied to the inner surface of dies, etc., because it is composed of a heating temperature control unit that heats the material by heating means arranged on the outer periphery and a cooling temperature control unit that cools the heated viscoelastic resin material. It is now possible to smoothly discharge the viscoelastic resin molded product from the die without applying the squeeze, and to achieve a viscoelastic resin molded product having sufficient shape retention even immediately after the discharge. Extrusion molding became possible. Therefore, since it is not necessary to provide multiple zones for simultaneously transporting a large number of cylindrical dies, the occupation area of the production line can be reduced, and the need to increase the occupation area when increasing the production capacity of the production line. Decreased.

  In addition, in the continuous molding apparatus for viscoelastic resin molded products having the above-described characteristic configuration, even when it is desired to manufacture a plurality of types of viscoelastic resin molded products having different shapes, it is only necessary to change the die to a die having different inner dimensions and shapes. Since the shape of the elastic resin molded product can be changed, the number of newly required facilities such as a large number of cylindrical dies having different shapes can be reduced as in the prior art.

  Furthermore, in the continuous molding apparatus for viscoelastic resin molded products having the above-described characteristic configuration, when it is desired to manufacture a plurality of types of viscoelastic resin molded products having different shapes, it is only necessary to change to a die having different inner dimensions and shapes. The shape change of the viscoelastic resin molded product is completed in a short time.

  In particular, viscoelastic resin materials with suitable properties as cushioning materials installed in beds and sofas generally have a cross-sectional shape of the die part that is discharged from the die part based on the property that the viscosity decreases as the temperature rises. Has the highest shape-retaining upper limit temperature in a range in which the mold can be held, and the lowest releasability lower limit temperature in the range in which the molded product does not adhere to the inner surface of the die part in a layered manner. However, with this configuration, the heating temperature control unit having heating means with a predetermined capability, and the viscoelastic resin material positioned on the outer periphery of the outlet of the die unit have a temperature higher than the releasable lower limit temperature, The viscoelastic resin material located on the center side with respect to the radial direction of the outlet of the part is provided with a cooling temperature control part that is lower than the shape retention upper limit temperature, so that it can be smoothly discharged from the die and the target length by the cutter In addition, it is possible to produce a viscoelastic resin molded article having a sufficiently stable shape even after being discharged in a sufficiently stable state even when cut into pieces.

Another feature of the present invention is as follows:

  With this configuration, the viscoelastic resin material positioned between the quantitative conveyance device and the extruder is conveyed under a constant high pressure condition, so that the bubbles contained in the viscoelastic resin material are integrated with each other upstream. The viscoelastic resin material on the downstream side of the quantitative conveyance device is in a high-density state with few bubbles, and the viscoelastic resin with stable physical properties from the die part. The molded product is discharged.

The characteristic configuration of the continuous molding method of the viscoelastic resin molded product according to the present invention is:

In addition, since it became possible to simultaneously achieve a viscoelastic resin molded product having sufficient shape retention immediately after discharge, continuous extrusion molding was possible. Therefore, it is not necessary to provide a plurality of zones for simultaneously transporting a large number of cylindrical molds, so that the occupation area of the production line can be reduced, and the occupation area needs to be increased even when the production capacity of the production line is increased. Is gone. Similarly, if you want to manufacture multiple types of viscoelastic resin molded products with different shapes, you can change the shape of the viscoelastic resin molded products with fewer new facilities such as a large number of cylindrical molds with different shapes. Can be obtained in a short time.

EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated, referring drawings.
(Schematic configuration of continuous molding equipment)
A viscoelastic resin molded article continuous molding apparatus 1 shown in FIG. 1 mainly includes an extruder 3 that extrudes a charged viscoelastic resin material A along an axial direction, and a viscosity that is fed by the extruder 3. A gear pump 5 (an example of a quantitative conveyance device) that sends the elastic resin material A further downstream at a constant speed, and a temperature at which the viscoelastic resin material A sent by the gear pump 5 is conveyed to the downstream side in a sealed state while adjusting the temperature. A control unit 6 and a die unit 7 for extruding the viscoelastic resin material sent through the temperature control unit 6 into a predetermined cross-sectional shape are generally connected in series in a horizontal posture.

  On the downstream side of the die portion 7, a cutter device 8 for cutting the viscoelastic resin molded body B extruded from the die portion 7 with a predetermined length into a viscoelastic resin molded product B ′, and cutting A belt conveyor 9 for separating the viscoelastic resin molded product B ′ obtained in this manner from the die portion 7 further downstream is disposed. As the cutter device 8, a steel wire cutter that moves one steel wire 8 </ b> A stretched sideways in the vertical direction by a motor M <b> 3 and a crank device (not shown) is used.

(Configuration of viscoelastic resin material)
As the viscoelastic resin material A, a material obtained by kneading a styrene elastomer and a paraffinic process oil is used, and an appropriate amount of an antiaging agent and an extender are added to the viscoelastic resin material A. The use ratio of the styrene-based elastomer and the paraffin-based process oil is not particularly limited. Here, it is assumed that the viscoelastic resin molded body B discharged from the die portion 7 is used as a cushioning material such as a bed. The ratio of the system process oil is 70% or more.

  This viscoelastic resin material A is basically extremely soft and easily deformed, has adhesiveness, and has a characteristic that the viscosity decreases as the temperature increases. As a result, if the temperature in the vicinity of the outer peripheral surface of the viscoelastic resin molded body discharged from the die portion 7 is about 120 ° C. or less, a tendency to adhere to the inner surface of the die portion 7 appears, and the outer peripheral surface has a scale-like shape. Therefore, there is a tendency that a cylindrical product with a smooth appearance cannot be obtained. Conversely, if the temperature near the center of the viscoelastic resin molded body discharged from the die portion 7 is about 160 ° C. or higher, the molded product discharged from the die portion 7 cannot show sufficient shape retention, Since it collapses by its own weight, there is a tendency that a regular cylindrical product having a desired outer diameter cannot be obtained.

Here, the lowest temperature (releasing mold release temperature) of the viscoelastic resin material A is set to about 125 ° C. within a range where the outer peripheral portion of the molded body discharged from the die portion 7 does not adhere to the inner surface of the die portion 7 in a layered manner. .
In addition, the molded article discharged from the die portion 7 exhibits sufficient shape retention, and the highest temperature of the viscoelastic resin material A within the range in which a regular cylindrical product having a desired outer diameter can be obtained (shape retention). The upper limit temperature is about 155 ° C.

(Configuration from extruder to gear pump)
Although the method for charging the raw material viscoelastic resin material A into the hopper 3C of the extruder 3 is not particularly limited, as illustrated in FIG. 1, the viscoelastic resin material is positioned adjacent to the continuous molding apparatus 1. You may arrange | position the resin material supply apparatus 20 for heat-kneading A and supplying sequentially to the hopper 3C by a batch type. Here, generally, viscoelastic resin material A having the same temperature as room temperature is supplied to hopper 3C.

  The extruder 3 has a configuration in which a single-axis screw 3B that is rotationally driven by a motor M1 and a speed reducer 2 is provided in a cylindrical case 3A. A hopper 3C for charging the viscoelastic resin material A is connected to an opening formed near the upstream end of the case 3A. The case 3A has a sealed structure except for the opening. In addition, changes, such as making the extruder 3 into a biaxial screw type, can be performed suitably.

  A plurality of first planar heaters 12 for heating the internal viscoelastic resin material A from the outer periphery are appropriately attached to the outer periphery of the case 3A. A first temperature sensor TC1 for detecting the temperature of the internal viscoelastic resin material A is disposed at least at the downstream end of the case 3A, and the control device 30 described later detects the detected value of the first temperature sensor TC1. Is driven at about 150 ° C., the first planar heater 12 is driven.

  Since the gear pump 5 uses a single-shaft drive type in which one of a pair of upper and lower gears always meshed with each other is driven to rotate by the motor M2, if the extruder 3 is operated with the gear pump 5 stopped, a viscoelastic resin material is used. A cannot substantially move downstream beyond the gear pump 5. When the gear pump 5 is driven, the viscoelastic resin material A is once divided into small pieces by a pair of upper and lower gears, and is integrated again at the small-diameter portion on the outlet side of the gear pump 5, and then the laminar flow state until the die portion 7. It is estimated that it is conveyed by

  A sealed cylindrical pressure adjusting unit 4 is interposed between the extruder 3 and the gear pump 5. A part of the inner wall surface of the pressure adjusting unit 4 is filled in the pressure adjusting unit 4. A pressure sensor PS for detecting the pressure of the viscoelastic resin material A is installed. A first planar heater 12 for heating the internal viscoelastic resin material A from the outer periphery is also appropriately attached to the outer periphery of the pressure adjusting unit 4.

(Control device and its operation)
The continuous molding apparatus 1 is provided with a control device 30 for controlling the operating state of each part. In actual operation of the continuous molding apparatus 1, first, a target discharge speed of the viscoelastic resin molded body B from the die portion 7 is set, and the rotational speed of the gear pump 5 that is generally uniquely determined based on this target discharge speed. Is manually input to the control device 30.

  The control device 30 rotates the motor M1 of the extruder 3 so that the detected value of the pressure sensor PS of the pressure adjusting unit 4 falls within the range of 0.8 to 1.2 MPa under the rotational speed condition of the gear pump 5 at that time. Speed control is performed. Thereafter, the rotational speed of the gear pump 5 and the detection target value of the pressure sensor PS can be appropriately set and changed so that the state of the viscoelastic resin molded body B discharged from the die portion 7 is suitable.

  As described above, the rotational speed of the motor M1 of the extruder 3 is controlled so that the detected value of the pressure sensor PS of the pressure adjusting unit 4 is always 0.8 MPa or more, so that the viscoelastic resin material A The contained bubbles can be moved upstream and driven out of the machine from the hopper 3C. As a result, a viscoelastic resin molded product B ′ having a sufficiently high density and stable physical properties can be obtained.

  The target size of the viscoelastic resin molded body B discharged from the die portion 7 is a columnar shape having an outer diameter of about 50 mm and a length of about 15 mm to 50 mm. Correspondingly, the inner diameter of the die part 7 is about 54 mm, the inner diameter of the extruder 3 and the pressure adjusting part 4 is consistently about 65 mm, the inner diameter of the outlet side of the gear pump 5 is about 42 mm, and the temperature-controlled conveyance. The inner diameter of the portion 6 is consistently about 50 mm.

(Configuration and operation of temperature control transport unit)
As illustrated in FIG. 2, the temperature control conveyance unit 6 includes a cylindrical case 6 </ b> C having a smooth inner surface with a circular cross section. The shape of the case 6C is generally constant over the entire length of the outer surface and the inner surface, but the case 6C has a heating temperature adjusting unit 6A in the first half and a cooling temperature adjusting unit 6B in the second half along the conveying direction of the viscoelastic resin material A For convenience. A second planar heater 14 (an example of a heating unit) for reheating the internal viscoelastic resin material A is disposed on the outer periphery of the heating temperature adjusting unit 6A in the first half. The latter-half cooling temperature adjusting unit 6B is not provided with a heating means such as a heater, and has a role of cooling the viscoelastic resin material A heated by the heating temperature adjusting unit 6A by a predetermined method.

  More specifically, in this embodiment, the cross-sectional shape of the outer periphery of the case 6C of the temperature control conveyance unit 6 is a square having a side length of about 100 mm, and the inner diameter is about 60 mm at the center of the square. A circular inner surface is formed. As a material of the case 6C, aluminum is selected because of its high thermal conductivity. In the heating temperature adjusting unit 6A, the square second planar heaters 14 are attached to all four surfaces of the case 6C having a square cross section. A second temperature sensor TC2 that detects the temperature of the viscoelastic resin material A that moves near the outer periphery is disposed between the heating temperature adjustment unit 6A in the first half and the cooling temperature adjustment unit 6B in the second half.

The viscoelastic resin material A located at the upstream end of the heating temperature control unit 6A (such as the point X on the upstream side of the second planar heater 14) has an outer peripheral side and a center portion inside the heating temperature control unit 6A. Regardless, the temperature is maintained at about 140 ° C. by the above-described extruder 3 and the first planar heater 12 of the pressure adjusting unit 4.
As will be described later, the viscoelastic resin material A located at the point X moves to the cool-down temperature adjustment unit 6B on the downstream side while being reheated by the second planar heater 14 of the heating temperature adjustment unit 6A.

  In particular, the viscoelastic resin material A in the vicinity of the outer periphery is once heated to about 160 ° C. by the second planar heater 14 and then gradually cooled by the cooling temperature control unit 6B, and finally the releasable lower limit temperature (125 Since it is discharged from the die portion 7 at about 150 ° C., which is sufficiently higher than (° C.), the tendency to adhere to the inner surface of the die portion 7 in a layered manner is suppressed, and a cylindrical product having a smooth appearance can be obtained. The control device 30 drives the second planar heater 14 based on the detection value of the second temperature sensor TC2.

  Further, the viscoelastic resin material A in the vicinity of the center in the radial direction is once heated to about 130 to 160 ° C. by the second planar heater 14, and then finally gradually cooled down by the cooling temperature control unit 6 B. Since it is discharged from the die part 7 at about 130 to 140 ° C. which is sufficiently lower than the upper limit temperature (155 ° C.), the molded product discharged from the die part 7 exhibits sufficient shape retention and collapses by its own weight. Without obtaining a regular cylindrical product having a desired outer diameter.

  The inner surfaces of the case 6A and the die part 7 of the temperature control and conveyance unit 6 are simply made of aluminum with high smoothness, and a special coating process for improving releasability from the viscoelastic resin material A, etc. Nothing has been given.

  If the viscoelastic resin molding B can be discharged from the die part 7 under the condition that the whole including the vicinity of the outer periphery and the center is uniformly 130 ° C., it is said that the temperature is higher than the lower limit of releasability (125 ° C.). The conditions and lower than the shape retention upper limit temperature (155 ° C.) can be cleared at the same time. However, in actuality, in the viscoelastic resin molding B that moves in a laminar flow state, the viscoelastic resin material A near the outer periphery is viscoelastic resin material near the center due to thermal diffusion that occurs around the outer periphery of the case 6A. Since the temperature is likely to be lower than that of A, it is difficult to make the temperature uniform around the outer periphery and near the center. Moreover, since the condition that it is higher than the releasability lower limit temperature (125 ° C.) and the condition that it is lower than the shape retention upper limit temperature (155 ° C.) cannot be sufficiently cleared, the obtained viscoelastic resin molded product B ′ Quality tends to be unstable.

  Incidentally, the second planar heater 14 is arranged on the entire surface including the latter half of the temperature control conveyance unit 6 or is arranged only on the latter half of the temperature adjustment conveyance unit 6, and the viscoelastic resin near the outer periphery of the die unit 7. In the method in which the material A is controlled to be about 160 ° C. sufficiently exceeding the releasable lower limit temperature (125 ° C.), the temperature of the viscoelastic resin material A near the center increases due to heat accumulation in the center side. It is difficult to control the viscoelastic resin material A at a location to a temperature sufficiently lower than the shape retention upper limit temperature (155 ° C.).

  The viscoelastic resin molded body B ′ discharged from the die part 7 has viscoelasticity and other rheological characteristics and adhesion to the inner surface of the production apparatus, the composition of the viscoelastic resin material A, the extruder 3 and the pressure adjusting part 4 The pressure applied to the viscoelastic resin material A, the residence time during which the viscoelastic resin material A stays in the pressure adjusting unit 4, the inner diameter of the die unit 7, the feed rate by the gear pump 5, etc. Therefore, the specific values of the releasability lower limit temperature and the shape retention upper limit temperature described above are merely examples, and it is estimated that these temperature values also vary depending on the above parameters.

  The cross-sectional shape of the viscoelastic resin molded body B discharged from the die part 7 can be changed as appropriate by changing the shape of the opening part of the die part 7, and a plurality of openings are provided in the die part 7. By providing, it is also possible to discharge a plurality of viscoelastic resin molded bodies B at the same time.

  The present invention can be used as a technique for continuously molding a viscoelastic resin material that is extremely soft and easily deformed and has adhesiveness into a molded product having a shape suitable as a cushion material to be installed in a bed or a sofa.
