Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, the common basic matter of two embodiment of the manufacturing method of the heat insulation panel demonstrated below is demonstrated.

  In the manufacturing method of the heat insulating panel, the panel base portion 20 provided with the vacuum heat insulating material 14 in the central portion in the width direction of the surface material 11 is described as a foaming heat insulating material injection machine 31 (hereinafter simply referred to as an injection machine 31). ), The foamable heat insulating material 16 is filled into the panel base portion 20 from the upper surface side. The panel base portion 20 includes an end panel 15 adjacent to an end portion in a direction orthogonal to the width direction of the vacuum heat insulating material 14. In addition, the end panel 15 is disposed at least at both ends in a direction orthogonal to the width direction of the panel base portion 20, and the thickness and width dimensions of the vacuum heat insulating material 14 and the end panel 15 are substantially the same (above). 1 to 4 and 5).

  Subsequently, the detail of the manufacturing method of the heat insulation panel which concerns on embodiment shown in FIGS. 1-4 is demonstrated.

  The heat insulating panel 10 manufactured by this manufacturing method is a rectangular flat plate that is used by being attached to a floor, wall, ceiling, or the like of a house. As described above, the heat insulating panel 10 is provided with the vacuum heat insulating material 14 and the end panel 15 between the surface material 11 and the back surface material 12, and around the vacuum heat insulating material 14 and the end panel 15. Has a structure filled with a foamable heat insulating material 16.

  In addition, in the manufacturing method of this heat insulation panel, it arranges and manufactures the surface material 11 on the lower side, and the heat insulation panel 10 is manufactured so that the back surface material 12 may be arranged on the upper part. Therefore, in the present specification, the upper and lower sides are defined based on this vertical relationship.

  In the manufacturing method of this heat insulation panel, the panel base part 20 shown in FIG. 1 is used. In this embodiment, as shown in FIG. 2, the method of manufacturing the heat insulation panel 10 is employ | adopted, conveying this panel base part 20 with the conveying apparatus 30 (belt conveyor).

  In this manufacturing method, the base of the panel in a state where the top and bottom of the heat insulating panel 10 is reversed, that is, the surface material 11 is down and the vacuum heat insulating material 14 and the end panel 15 are arranged thereon. 20 is transported by the transport device 30.

  As shown in FIG. 1, the panel base portion 20 has a rectangular shape in plan view, and frame portions 13 projecting to the surface side are formed at both ends in the short direction (width direction) of the surface material 11 forming the outer shape. Is provided. Between the frame portions 13 on the upper surface side of the surface material 11, row blocks 25 arranged in the width direction are arranged. Each of the row blocks 25 is formed by alternately arranging two identical rectangular vacuum heat insulating materials 14 and three end panels 15 in one row.

  Between the row blocks 25, that is, between the vacuum heat insulating materials 14 arranged in the width direction, a space is formed from the end portion in the longitudinal direction of the surface material 11 to the other end portion, and the outer side in the width direction of each row block 25. In addition, a space is provided from the end in the longitudinal direction of the surface material 11 to the other end. Thus, all of the four vacuum heat insulating materials 14 are arranged so as not to contact the four end edges of the surface material 11 and to be in contact with the central portion in the width direction.

  An end panel 15 made of a heat insulating material is disposed between the two vacuum heat insulating materials 14 in the row block 25, and the end panels 15 are also provided on both outer sides in the longitudinal direction of the vacuum heat insulating materials 14 in the row block 25. It is arranged. These three end panels 15 are arranged so as to be adjacent to the vacuum heat insulating material 14, and the end panels 15 on both end sides are arranged without a gap until reaching the end face of the end portion of the surface material 11. .

  These row blocks 25 have a constant height from the end in the longitudinal direction to the other end, and both side end surfaces in the width direction have almost no steps. That is, the thickness dimensions of the vacuum heat insulating material 14 and the end panel 15 in the row block 25 are substantially the same, and the width dimensions thereof are also substantially the same. In addition, there is no mutual relation about the length dimension of the longitudinal direction of the vacuum heat insulating material 14 and the edge part panel 15. FIG.

  Further, in the two rows of row blocks 25, the positional relationship between the vacuum heat insulating material 14 and the end panel 15 is the same. Note that the end panels 15 at both ends in the row block 25 are desirably the same length and shape as in the example of FIG. 1, but are not limited thereto. Further, the end panel 15 disposed between the two vacuum heat insulating materials 14 in the row block 25 is preferably about twice as large as that disposed at both ends as in the example of FIG. Not.

  Next, further details including the material of each member will be described.

  As the surface material 11, a plate material made of wood, gypsum, resin or the like can be used. Further, the frame 13 can be a square bar made of a heat insulating resin such as wood or hard urethane, and its height should be larger than the thickness of the vacuum heat insulating material 14 and the end panel 15. Is desirable.

  As the vacuum heat insulating material 14, a material formed by covering the core material with a gas barrier packaging material and performing vacuum suction can be used. In particular, in the example of the present embodiment, a thin panel body is used in which the thickness dimension is smaller than the height dimension of the frame portion 13 and the planar view shape is substantially rectangular.

  As described above, the end panel 15 is preferably formed of a heat insulating material, and particularly preferably formed of the same material as the foamable heat insulating material 16 described later. For example, what was manufactured using hard foaming urethane, foaming polyethylene, etc. can be used conveniently. Further, the end panel 15 made of glass wool may be used.

  Moreover, as shown in the enlarged partial longitudinal sectional view of FIG. 1B, the end panel 15 has an opening hole 15a communicating in the thickness direction. It is desirable that a large number of minute apertures 15a are formed as shown in a satin shape in FIG. The opening hole 15a is a hole for allowing the liquid material 16a of the foamable heat insulating material 16 to be injected in the manufacturing process of the heat insulating panel 10 to penetrate from the top to the bottom.

  Such a panel base part 20 is conveyed using the conveying apparatus 30 in the state accommodated in the recessed part 21a of the tray 21 (refer FIG. 3). The tray 21 has a shape of a wide concave groove with a rectangular shape in plan view having a concave portion 21a on which the panel base portion 20 can be placed and accommodated, and at the upper ends of the wall portions 21b and 21b formed at both ends in the width direction. Handle pieces 21c and 21c extending outward are formed.

  In this way, the panel base 20 is carried into the transport device 30 for injecting the foamable heat insulating material 16 while being accommodated in the tray 21, and the foamable heat insulating material is injected in the transport process while being transported on the transport device 30. A process and a back surface material mounting process are sequentially executed. In addition, it is good also as a manufacturing method which produces | generates panel base part 20 itself on the conveying apparatus 30 before manufacturing as follows.

  The conveying apparatus 30 is comprised with the belt conveyor as shown in FIG. There is a carry-in entrance 30a in the upstream portion of the transfer device 30, and a foaming heat insulating material injection machine 31 is arranged in the middle stream portion so that the liquid material 16a of the foam heat insulating material 16 can be injected from the nozzle 31a. On the downstream side of the injection machine 31, a roller device 32 is disposed that feeds the back material 12 to be adhered to the upper surface of the filled foamable heat insulating material 16 onto a conveyor that conveys the material. Further, on the downstream side, a thickness regulating device 33 constituted by another conveyor device is arranged in parallel along the conveying device 30. In addition, as the conveying apparatus 30, it may replace with a belt conveyor and may use the roller conveyor which has arrange | positioned many rollers in a row.

  In addition, as for the tray 21 transported on the transport device 30, a plurality of things are used as shown in the example of FIG. 2 in consideration of the outflow of the foamable heat insulating material 16 from the leading end of the tray 21 in the moving direction. It is desirable to continuously arrange and transport without gaps. That is, by arranging the trays 21 without gaps, it is possible to execute a continuous operation with a constant injection amount without interrupting the injection of the foamable heat insulating material 16 or controlling the injection amount.

  In the foaming heat insulating material injection machine 31, the liquid material 16a before foaming of the foaming heat insulating material 16 is accommodated, and with respect to the tray 21 (the recess of the panel base portion 20) conveyed on the conveyor, The liquid material 16a can be injected from the nozzle 31a. The injector 31 is configured to move in the width direction so as to cross the longitudinal direction of the panel base portion 20, and this will be described later in the description of FIG.

  As the foamable heat insulating material 16, various foam-based (foamed) materials such as hard foamed urethane, foamed polyethylene, and foamed polystyrene are used. At the time of injection, the foamable heat insulating material 16 is prepared as a liquid material 16a before foaming.

  The liquid material 16 a is ejected from the tip 31 to the tail end of the tray 21 from the nozzle 31 a of the foaming heat insulating material injection machine 31. The liquid material 16a gradually foams in the recesses between the frame portions 13 of the panel base portion 20 placed in the tray 21 over time after being injected. The foamable heat insulating material 16 is in close contact with the inner bottom surface of the panel base portion 20, the inner wall of the frame portion 13, the vacuum heat insulating material 14 and the outer surface of the end panel 15.

  In this foaming process, since the foamable heat insulating material 16 is in a liquid state, it tends to flow in various directions. However, since the liquid material 16a heading in the moving direction flows to the adjacent trays 21, it does not flow out of the transport device 30. Moreover, although the liquid material 16a tends to flow in the width direction, the frame portions 13 and 13 act as weirs and therefore do not flow outward. By continuously injecting in this way, the foamable heat insulating material 16 can be used without waste and efficient production can be performed.

  The liquid material 16a is filled between the two row blocks 25 (the vacuum heat insulating material 14 and the end panel 15) disposed in the center portion in the width direction of the panel base portion 20 and on the outer side in the width direction of the row blocks 25. The two row blocks 25 are also filled.

  Since the end panel 15 has a large number of opening holes 15 a communicating in the vertical direction, the liquid material 16 a enters the opening hole 15 a from the upper surface of the end panel 15 and reaches the lower surface. Then, the liquid material 16 a penetrates the lower surface through the opening hole 15 a and reaches the surface of the surface material 11. Further, the liquid material 16 a slightly enters between the end panel 15 and the surface material 11.

  Next, in the foaming process of the foamable heat insulating material 16, the sheet-like back surface material 12 is pulled out from the roller device 32, and the upper surface of the panel base portion 20 filled with the foamable heat insulating material 16 is pressed by the thickness regulating device 33. Is pasted. At the same time, the thickness of the heat insulating panel 10 is regulated to a constant thickness. During this pressing, excess foaming heat insulating material 16 is discharged from the end of the tray 21.

  The liquid material 16a of the foamable heat insulating material 16 is gradually solidified while being foamed, and at the same time, the foamable heat insulating material 16 itself is in contact with the vacuum heat insulating material 14, the end panel 15, and the surface material 11. It will be in the state where it adhered. Further, the foamable heat insulating material 16 that has reached the surface of the surface material 11 through the opening hole 15 a of the end panel 15 is also solidified in a state of being bonded to the surface material 11. Thus, the end panel 15 is fixed to the surface of the surface material 11.

  In this way, the heat insulating panel 10 having a certain thickness and filled with the foamable heat insulating material 16 and attached with the back surface material 12 is carried out from the carry-out port 30b in a state of being accommodated in the tray 21, and the next step. It is conveyed to.

  And the continuous heat insulation panel 10 manufactured in this way is isolate | separated for every tray 21 in a cutting process. Furthermore, the thermal insulation panel 10 isolate | separated for every tray 21 (panel base part 20) performs a division | segmentation process about the case where further division | segmentation is required.

  As described later, as will be described later, a step of cutting a portion (center end panel 15) between the vacuum heat insulating materials 14 along the width direction of the panel base portion 20 after the foamable heat insulating material is filled. Including. Such a process may be included in the cutting process. For example, the tray 21 may be removed from the heat insulating panel 10 to which the back material 12 is attached, and the heat insulating panel 10 continuously connected in this manner may be divided at the position of the end panel 15. This dividing step will be described later together with the description of FIG.

  Next, an injection mode of the foamable heat insulating material 16 by the injection machine 31 in the width direction of the panel base portion 20 will be described with reference to FIG. FIG. 3A is an aspect used in this embodiment, and FIG. 3B is another aspect. 3A and 3B are longitudinal sectional views when the panel base portion 20 placed on the tray 21 is cut in the width direction.

  In the present embodiment, as shown in FIG. 3A, one injector 31 is movable in the width direction. That is, the panel base 20 moves relative to the injector 31 also in the width direction.

  The injector 31 is controlled by a control unit (not shown) configured by a CPU or the like, and varies the amount of the liquid material 16a ejected from the nozzle 31a depending on the position while moving in the width direction.

  More specifically, the injector 31 injects a small amount of liquid material 16 a onto the vacuum heat insulating material 14 and the end panel 15 constituting the row block 25, while between the row blocks 25 and outside the row block 25. In this case, a large amount of liquid material 16a is injected. In this way, the filling amount of the foamable heat insulating material 16 is varied in the width direction of the panel base portion 20. Thus, the injector 31 discriminates the site where the row block 25 exists and the site where it does not exist in the width direction, that is, considering the difference in the depth dimension of the filling space of the foamable heat insulating material 16, I try to make them different. This determination may be made by specifying a position in the width direction in advance or by measuring the depth with a sensor.

  Thus, since the filling amount is variable in the width direction, it is possible to fill with an appropriate liquid material 16a corresponding to the required amount of the foamable heat insulating material 16 for each region in the width direction. As a result, the occurrence of unevenness in the width direction on the surface of the back surface material 12 of the heat insulating panel 10 can be reduced.

  As shown in FIG. 3B, a plurality of injectors 31 may be arranged along the width direction. By doing in this way, like FIG. 3A, it can be filled more in the site | part of the intermediate position of a width direction, and the position of both ends than the foaming heat insulating material 16 with which it fills to the upper surface side of the row | line | column block 25. The foamable heat insulating material 16 can be filled in a well-balanced manner in the width direction.

  Next, the heat insulation panel 10 cut and formed corresponding to one panel base portion 20 will be described with reference to FIGS.

  As shown to Fig.4 (a), this heat insulation panel 10 contains one panel base part 20 shown to Fig.1 (a). That is, the heat insulating panel 10 includes two row blocks 25 in which the end panel 15, the vacuum heat insulating material 14, the end panel 15, the vacuum heat insulating material 14, and the end panel 15 are arranged in order.

  The row block 25 has substantially the same width dimension from the end portion in the longitudinal direction of the heat insulating panel 10 to the other end portion, and there are almost no steps on both side end surfaces in the lateral direction. As shown in Fig. 5, the shape and position are substantially the same regardless of the members in the longitudinal sectional view. Further, as illustrated in FIGS. 4B and 4C, the height of the row block 25 is constant over the entire length in the longitudinal direction.

  Thus, in the heat insulation panel 10, the rectangular column block 25 is formed in a plan view in the entire length in the longitudinal direction, and the column block 25 has a constant height. Therefore, at least for the entire length of the row block 25, as long as the filling amount of the foamable heat insulating material 16 is made uniform, the possibility that the surface of the back surface material 12 disposed on the upper side is uneven is low.

  Furthermore, as described above, since the filling amount of the foamable heat insulating material 16 is different for each part in the width direction, the thin space above the row block 25 is filled with more foamable heat insulating material 16 than necessary. Can be avoided. Therefore, the unevenness | corrugation of the surface of the back surface material 12 in the width direction of the heat insulation panel 10 is hard to be made.

  The heat insulation panel 10 of the present embodiment includes two row blocks 25, and a portion where only the foamable heat insulating material 16 is disposed is formed between them. However, there is a low possibility that unevenness is also formed in this portion. In this way, even when a plurality of row blocks 25 are arranged at intervals, the unevenness can be reduced by controlling the filling amount of the foamable heat insulating material 16 in the width direction. Therefore, the heat insulation panel having three or more row blocks 25 May be formed and then cut.

  Moreover, this heat insulation panel 10 can also be cut | disconnected along the width direction. Specifically, it can be cut at the position where the end panel 15 is arranged, for example, by cutting at an intermediate position indicated by a two-dot chain line in the longitudinal direction in FIG. can do. Moreover, the edge part of the longitudinal direction of the heat insulation panel 10 can also be cut off within the range where the edge part panel 15 was distribute | arranged. As described above, the dividing step of continuously performing the cutting between the panel base portions 20 and the cutting along the two-dot chain line in FIG. It may be.

  In this way, since the end panel 15 is disposed at least at both ends in the longitudinal direction, the cutting is performed for the purpose of division within the range where the end panel 15 is disposed without damaging the vacuum heat insulating material 14. Can do.

  Further, the end panel 15 is substantially entirely fixed to the surface material 11 by the foamable heat insulating material 16 that has passed through the numerous opening holes 15a as described above. For this reason, even when the end panel 15 is cut within the range in which the end panel 15 is disposed, the fixed state between the end panel 15 and the surface material 11 is maintained. Therefore, as long as the part where the end panel 15 is arranged is cut, there is almost no possibility that the surface material 11 is peeled off at the cut end.

  As mentioned above, according to the heat insulation panel 10 manufactured with the manufacturing method of this heat insulation panel, the effect as mentioned above is produced. The heat insulation panel 10 having such a configuration is not limited to the above-described manufacturing method, and the same effects as described above can be obtained even if manufactured by other manufacturing methods. In short, the heat insulation panel 10 should just be the structure which is demonstrated below.

  The heat insulating panel 10 includes a panel base portion 20 having a vacuum heat insulating material 14 at the center in the width direction of the surface material 11, and a foam heat insulating material 16 filled on the upper surface side of the panel base portion 20 and the side in the width direction. And a back material 12 disposed on the upper surface side of the foamable heat insulating material 16. The panel base portion 20 includes an end panel 15 adjacent to an end portion in a direction orthogonal to the width direction of the vacuum heat insulating material 14. Moreover, the end panel 15 is disposed at least at both ends in the direction orthogonal to the width direction of the panel base portion 20, and the thickness and width dimensions of the vacuum heat insulating material 14 and the end panel 15 are substantially the same.

  Next, another embodiment of the method for manufacturing a heat insulating panel will be described with reference to FIG. The panel base 20 used in this manufacturing method has the same shape as that shown in FIG. Moreover, about the structure of the panel base part 20, the code | symbol same as FIG. 1 is attached | subjected and the description is omitted.

  In this manufacturing method, the liquid material 16a of the foamable heat insulating material 16 (FIG. 5) is used while the foaming heat insulating material injection machine 31 moves in the width direction of the panel base portion 20 without using the transfer device 30 (see FIG. 2). (Not shown, see FIG. 3). That is, the panel base 20 moves relative to the injector 31 along the width direction. In this manufacturing method, the panel base 20 is placed on the work table 35 and the foamable heat insulating material 16 is injected.

  The injection machine 31 shown in FIG. 5 has a length corresponding to the entire length of the panel base portion 20 in the longitudinal direction, and a plurality of nozzles 31a (not shown in the figure, see FIG. 3) are arranged on the lower surface thereof. Yes. The injector 31 is configured to fill the foamable heat insulating material 16 on the upper surface of the panel base portion 20 while moving in the width direction of the panel base portion 20.

  Similarly to the injection machine 31 shown in FIGS. 2 and 3, the filling amount of the foamable heat insulating material 16 is varied in the width direction of the panel base portion 20. Specifically, a portion where the row block 25 does not exist can be filled with more foamable heat insulating material 16 than the filling amount to the upper surface of the row block 25.

  In the manufacturing method shown in FIG. 5, in order to form both ends in the longitudinal direction of the heat insulating panel 10, a frame portion is also provided at both ends in the longitudinal direction, or foam is protruded from both ends without providing a frame portion. It is desirable to cut the heat insulating material 16. Further, when cutting off the protruding heat insulating material 16, a part of the end panel 15 may be cut and removed. Even if a part of the end panel 15 is cut, since the end panel 15 is almost entirely fixed to the surface material 11, there is no possibility that the surface material 11 is peeled off after cutting.

  In the above two embodiments, the heat insulation panel 10 including two column blocks 25 is illustrated, but it may include only one column block 25. As described above, three or more columns may be included. The blocks 25 may be arranged.

  Further, in the above two embodiments, the example in which the two vacuum heat insulating materials 14 are provided in the row block 25 is illustrated, but three or more vacuum heat insulating materials 14 may be included. Even in that case, the end panels 15 are arranged between the vacuum heat insulating materials 14. Therefore, the heat insulation panel 10 can be divided | segmented into plurality by cut | disconnecting along the width direction within the range of the edge part panel 15 between the vacuum heat insulating materials 15. FIG. Moreover, the row block 25 provided with only one vacuum heat insulating material 14 may be used. In that case, it cannot be cut or divided along the width direction, but cutting that removes a part of the end portion within the range of the end panel 15 arranged at both ends of the heat insulating panel 10 is possible. It is.
