Description

  The present invention mainly relates to a sandwich panel manufacturing apparatus and a sandwich panel manufacturing method for manufacturing a panel material used as a building material such as a wall material of a building.

Sandwich panels made by sandwiching a foamable resin material between an upper surface material and a lower surface material are excellent in heat resistance, flame retardancy, sound insulation and heat insulation, have a strong shape retention action, are lightweight and easy to handle. Widely used in building materials, freezers, partition walls of public facilities, etc.
As a method for manufacturing this type of sandwich panel, for example, there is a technique disclosed in Patent Documents 1-6.
In Patent Document 1, a split mold is used, and a pair of thermoplastic resin sheets are provided in a cavity. A flame retardant foamed resin core material is filled as a core material body between a pair of thermoplastic resin sheets. The core material body is held by pressing and welding the core material body to the thermoplastic resin sheet. By opening the split mold, the molded panel material is taken out, and the burr part of the pinch-off part is cut to complete the panel alone.

  In Patent Document 2, using a slat conveyor, a foamed stock solution composition is supplied from a mixing head between an upper surface material and a lower surface material, and a band-shaped sandwich panel is produced in which a foamable resin core material is sandwiched between them. In this manufacturing process, a nonwoven fabric is interposed between the conveying surface and the side surface located on both sides in the width direction of the sandwich panel, improving the gas release from the side surface and generating voids in the foamable synthetic resin. Is suppressed.

In Patent Document 3, a side belt is pressed against both sides in the width direction of the sandwich panel to prevent liquid leakage from the side surface of the sandwich panel, thereby preventing liquid leakage from both sides.
Patent Document 4 relates to a sandwich panel manufacturing facility in which the same applicant as the present application is the right holder. In this manufacturing facility, a foamable resin material is poured and filled into a rectangular frame conveyed on a belt conveyor, and after filling, a top panel and a bottom panel are bonded to the frame to continuously manufacture sandwich panels.
Patent document 5 has shown the manufacturing method which can continuously produce the sandwich panel which consists of FRP face material using a double conveyor. Patent Document 6 discloses an apparatus for manufacturing a sandwich panel having a uniform foam density by a batch-type multi-stage hot press.

JP2013-104267A JP 2008-238551 A JP 2005-178136 A Japanese Patent No. 5487354 JP 2010-173100 A JP 2006-256238 A

In Patent Document 1, since a core material body is welded to a thermoplastic resin sheet using a split mold, it is necessary to finely set the clamping force, clamping time, and cooling time. For this reason, it took time to manufacture the sandwich panel material by mold forming, which was a factor hindering good productivity.
In Patent Documents 2 and 3, since the foamable resin material existing in the cut surface of the sandwich panel is exposed, it is general to cover the cut surface with a covering material so as not to generate dust from the foamed resin material.

  For this reason, there is an inconvenience that a covering step for covering the cut surface is increased and productivity is lowered, and a cut piece (amount of material such as a foamable resin material) generated when the sandwich panel is cut is wasted.

In order to form a sandwich panel with a face material by setting a flexible layer such as paper or plastic sheet on the upper and lower surfaces, it is common to use the double conveyor of Patent Document 5 or the multistage hot press of Patent Document 6. It is.
In Patent Document 5, there is a problem that the equipment becomes large, the slat surface of the conveyor remains as a clog, and it is difficult to change the product width and thickness.

  In the multi-stage hot press of Patent Document 6, particularly when a frame is not provided, there is a possibility that the setting of the upper and lower surface members may be difficult or impossible. Patent Document 4 relates to a sandwich panel-formed body with a frame, and cannot be applied to a frameless structure.

  The present invention has been made in view of the above circumstances, and the object thereof is that a frame is unnecessary, equipment for manufacturing a continuous panel forming body is inexpensive, automation of the manufacturing is easy, product width and thickness. To provide a sandwich panel manufacturing apparatus and a sandwich panel manufacturing method that can be easily set to a desired length by cutting a continuous panel forming body with an arbitrary length. is there.

The side sealer blocks 13a and 13b are moved together.

  As the pinion motor 19d is energized forward and backward, the pinion 19c reciprocates along the horizontal rack 19b along the longitudinal direction R in FIG. 2, so that the rectangular bar unit 7 is integrated with the side sealer blocks 13a and 13b. And reciprocates along the moving direction S. Therefore, in the following description, the description of the operation of the pinion motor 19d, the pinion 19c, and the horizontal rack 19b is omitted, and only the expression that the rectangular bar unit 7 moves integrally with the side sealer blocks 13a and 13b.

As shown in FIG. 3, a rack 24 is mounted as a reciprocating mechanism on the lower surface of the side sealer block 13a (13b), and a motor having a rotating shaft 26a fitted with a pinion 25 below the rack 24. 26 is installed.
The side sealer block 13a (13b) is reciprocated by a predetermined distance along the moving direction S by rotating the motor 26 forward and backward with the pinion 25 engaged with the rack 24.

  At the front end of the side sealer block 13a (13b) in the moving direction S, there is a horizontal rack 27 arranged in an intersecting direction orthogonal to the moving direction S, and a gear 28 that meshes with the horizontal rack 27. A vertical motor 29 is provided as a block bar driving device so that it can move integrally with the side sealer block 13a (13b).

The side sealer block 13a (13b) can be slightly reciprocated along the contact / separation direction K with respect to the side paper 14 (15) by forward and reverse energization to the vertical motor 29.
Specifically, after the foamable synthetic resin material 30 is pressurized and aged at a carry-out position E to be described later, the side sealer block 13a (13b) is separated from the side paper 14 (15) (separated position), When the sealer block 13a (13b) returns from the unloading position E to a filling position F, which will be described later, the side sealer block 13a (13b) is pressed against the left and right end faces of the rectangular block bar 16 via the side paper 14 (15). Move (pressure contact position).

  That is, the block bar driving device reciprocates the side sealer blocks 13a and 13b in the crossing direction (separation direction K) orthogonal to the moving direction S, thereby causing the side sealers 13a and 13b to be side papers 14 and 15 Are provided so as to be movable between a press-contact position where the left and right end faces of the rectangular block bar 16 are pressed and a spaced position which is separated from the left and right end faces of the rectangular block bar 16.

  The mixing head 3 has a surrounding position at a filling position F that forms a surrounding area H surrounded by the side sealer blocks 13a and 13b, the rectangular block bar 16 and the rear end face 30e of the preceding foamable synthetic resin material 30 at the pressure contact position. A predetermined amount of foamable synthetic resin material 30 is supplied to H. Therefore, the mixing head 3 is provided so as to be movable between a position facing the surrounding area H and the outside of the surrounding area H.

  The mounting table 32 is provided with left and right side sealer blocks 13a (13b) slidable in the moving direction S and the separating / connecting direction K. As shown in FIG. And a top plate portion 32a and four legs 32b formed flat so as to be in sliding contact with the bottom paper 12.

The pressing plate 33 is provided as a surface plate so as to be slidable on the upper surface of the top paper 11 at an upper position corresponding to the mounting table 32, and can be moved up and down to temporarily press the top paper 11 against the mounting table 32. It is set to.
When the foaming synthetic resin material 30 is filled in the surrounding area H at the filling position F and moved to the carry-out position E, the sequence-type control unit 34 operates to extend the rod 35a of the air cylinder 35, thereby pressing the The plate 33 is driven and pressed against the top paper 11 so as to be in close contact with the top surface of the foamable synthetic resin material 30 in the surrounding area H on the side sealer blocks 13a and 13b and the rectangular block bar 16 for a predetermined time. Press contact (pressurization / aging process).

In other words, when the foamable synthetic resin material 30 enters a predetermined position (carrying-out position E), the pressing plate 33 descends to perform a pressurizing / aging process, and the pressing plate 33 includes the side sealer blocks 13a, 13b and It is placed on the rectangular block bar 16.
The side sealer blocks 13a and 13b are at the forward end in the molding direction, the width direction is also at the forward end, and the pressing plate 33 is positioned at the descending end. The pressing plate 33 is firmly in pressure contact with the side sealer blocks 13 a and 13 b and the rectangular block bar 16.

In the pressurizing / ripening step, the pressing plate 33 is lowered by several centimeters, and the upper plate 11 and the lower sheet 12 are sandwiched between the pressing plate 33 and the top plate 32 a of the mounting table 32.
For this reason, the release paper 17b is brought into contact with the rear end surface 30e located on the rear side when viewed from the moving direction in the foamable synthetic resin material 30, and the top paper 11 is adhered to the upper surface of the foamable synthetic resin material 30; The bottom paper 12 is bonded to the lower surface of the foamable synthetic resin material 30, and the side papers 14 and 15 are bonded to the left and right sides of the foamable synthetic resin material 30. The standing and aging time required for the foamable synthetic resin material 30 is usually as long as 2-10 minutes.

  When the continuous panel forming body 2P is manufactured according to the sandwich panel manufacturing method, the mixing head 3 is moved to a position facing the surrounding area H as shown in FIG. A predetermined amount of the composition is supplied as a foamable synthetic resin material 30 from the mixing head 3 (injection / filling step).

With the start of the filling / filling process, the motor 26 is energized in the forward direction for a predetermined time, causing the pinion 25 to rotate along the rack 24 in the forward direction. Thereby, as shown in FIG. 3, the side sealer blocks 13a and 13b are moved in the moving direction S from the filling position F together with the rectangular bar unit 7 while sandwiching the foamable synthetic resin material 30 as the continuous panel forming body 2P. Move along.
Along with the end of the filling / filling process of the foamable synthetic resin material 30, the side sealer blocks 13a and 13b and the rectangular bar unit 7 have reached the unloading position E adjacent to the filling position F (conveying / moving process). ). During this time, the foamable synthetic resin material 30 is filled, but this filling time is about 10 seconds and is short.

  That is, in the filling / filling step, the foamed synthetic resin material 30, the top paper 11, the bottom paper 12, the side papers 14 and 15, the side sealer blocks 13a and 13b, The rectangular bar unit 7 moves simultaneously by the length dimension U (for example, 3 meters) of the foamable synthetic resin material 30 as a product.

  When the pressurizing / ripening process at the unloading position E is completed, the control unit 34 raises the pressing plate 33 by several centimeters and separates it from the top sheet 11 (pressure canceling process). At the same time, the vertical motor 29 is temporarily energized in the positive direction to rotate the gear 28 along the horizontal rack 27 in the positive direction. As a result, as shown in FIG. 4, the side sealer block 13 a (13 b) moves from the pressure contact position along the separation / contact direction K to a separation position slightly separated from the left and right ends of the rectangular block bar 16.

  Following this, the motor 26 is temporarily energized in the reverse direction, causing the pinion 25 to rotate along the rack 24 in the reverse direction. Accordingly, as shown in FIG. 5, the side sealer block 13a (13b) is moved along with the rectangular bar unit 7 along the moving direction S while the foamable synthetic resin material 30 is disposed at the carry-out position E. Return from E to the original filling position F (returning / moving step).

Along with this, the drive motor 20 is energized temporarily, and the release paper 17 b is wound from the winding paper roller 17 by a predetermined amount by the rotation of the winding roll 18. That is, the release paper 17b is intermittently slid while sliding on the rectangular block bar, and the new release surface of the release paper 17b is opposed to the receding end Hw of the surrounding area H.
In this case, the side sealer block 13a (13b) is returned to the retracted end by the length of the product, and the rectangular bar unit 7 slides the release paper 17b by a necessary amount to expose the new release surface on the front surface. ing. At this time, the rear end portion 30 e of the foamable synthetic resin material 30 that has moved to the carry-out position E is incorporated into the constituent member of the surrounding region H.

  When returning to the filling position F, the vertical motor 29 is temporarily energized in the reverse direction, whereby the gear 28 is rotated in the reverse direction along the horizontal rack 27. Along with this, the side sealer blocks 13a and 13b move along the separating / connecting direction K, and the side sealer blocks 13a and 13b are moved to the left and right ends of the rectangular block bar 16 via the left and right side papers 14 and 15, respectively. The pressure has returned to the original pressure contact position (see FIG. 1A).

  Thereby, the left and right side sealer blocks 13a (13b), the rectangular block bar 16, and the rear end face 30e of the foamable synthetic resin material 30 are used as a new surrounding area H for forming the next foamable synthetic resin material 30. Arrangement is completed and preparation for filling / filling of the foaming stock solution composition is completed (standby / preparation step).

  Each time the side sealer block 13a (13b) moves from the filling position F to the carry-out position E, the foamable synthetic resin material 30 to which the top paper 11, the bottom paper 12, and the left and right side papers 14 and 15 are bonded is continuous. The panel forming body 2P is pushed out by the product length dimension U and is intermittently conveyed from the unloading position E to the outside (conveying / moving step). The continuous panel forming body 2P conveyed to the outside can be cut into a product length dimension U in a cutting process and commercialized as a single panel forming body.

In the first embodiment, the top paper 11 is bonded to the top surface of the foamable synthetic resin material 30 and the bottom paper 12 is attached to the bottom surface of the foamable synthetic resin material 30 as the foamable synthetic resin material 30 is injected and filled into the surrounding area H. The side papers 14 and 15 are adhered to the left and right side portions of the foamable synthetic resin material 30, and the release paper 17 b is positioned on the subsequent side of the foamable synthetic resin material 30 as viewed from the moving direction S. Press contact with the rear end 30e.

For this reason, a frame for injecting and filling the foamable synthetic resin material 30 is not required, and the top paper 11, the bottom paper 12, and the left and right side papers 14 and 15 are closely bonded to the foamable synthetic resin material 30 without a gap. And strengthens the overall rigidity. And the whole continuous panel formation body 2P becomes streamlined, the appearance of an external appearance improves, the heat inflow / outflow is prevented, and the favorable heat insulation of a continuous panel formation body can be hold | maintained.
In addition, the equipment for manufacturing the continuous panel forming body is inexpensive, the manufacturing is easy to automate, the dimensional conditions such as product width and thickness can be easily changed, and the continuous panel forming body 2P is cut at an arbitrary length. By doing so, it becomes possible to set to a free length dimension.

  In particular, the top paper 11 and the bottom paper 12 are pulled by the movement of the side sealer block 13a (13b) to the carry-out position E, and therefore both receive tensile force (tension). For this reason, the upper surface paper 11 and the lower surface paper 12 are pulled with no slack to form a uniform flat surface without unevenness, and closely contact the upper surface and the lower surface of the foamable synthetic resin material 30 without any gap. This close contact structure can prevent heat from flowing in and out of the foamable synthetic resin material 30 and maintain good heat insulation of the panel forming body.

  In addition, since the foaming synthetic resin material 30 is directly injected and filled in the surrounding area H surrounded by the left and right side sealer blocks 13a and 13b and the rectangular block bar 16, it is advantageous in terms of cost. The panel forming body can be manufactured smoothly and in a short time, and can contribute to the improvement of productivity for the continuous panel forming body 2P.

In the rectangular bar unit 7, since the left and right bracket arm plates 19 are used, the mounting structure of the winding roll 18, the paper roll 17 and the rectangular block bar 16 is simplified, which is advantageous in terms of cost.
Since the side sealer blocks 13a and 13b can be reciprocated alternately with a simple structure such as the pinion 25, the rack 24, and the motor 26, space can be saved.

  Further, the gear 28, the horizontal rack 27, and the vertical motor 29 enable displacement of the side sealer blocks 13a and 13b in the contact / separation direction K with respect to the side sheets 14 and 15. For this reason, the drive structure of the side sealer blocks 13a and 13b is simplified, which can contribute to space saving and cost reduction.

  When the foamable synthetic resin material 30 is filled for the first time, the foamable synthetic resin is placed at a position on the preceding side as seen from the moving direction S of the side sealer blocks 13a and 13b (see the left and right front separated end portions 17B shown in FIG. 1). The resin material 30 is inflow arranged as a precursor forming body, and filling molding is performed as usual. Thereby, it can shape | mold without waste as a regular product which integrated the precursor formation body with the continuous panel formation body.

(Modification)
(A) As a use object of a single panel molded object, you may produce as a general wall material, a heat insulation wall, a top plate of a desk, and a door panel besides the building materials of a building.
(B) As a material for the top paper 11 and the bottom paper 12, any material can be used as long as it is a flexible face material in addition to natural paper such as Japanese paper or synthetic paper.

(C) The upper roller 2c and the lower roller 6b are rotationally driven in only one direction in conjunction with the moving direction S of the side sealer blocks 13a and 13b, and are moved to the upper paper 11 and the lower paper 12 in the feeding direction. May be given.
(D) The foaming stock solution composition and the foamable synthetic resin material 30 (product) are originally different from each other, but in the present embodiment, they are described without distinguishing both from the viewpoint of convenience.
(E) A plurality of sandwich panel manufacturing apparatuses 1 are juxtaposed in the horizontal direction, and the foaming synthetic resin material 30 is injected and filled into the surrounding area H of each manufacturing apparatus 1 in a predetermined order using the mixing head 3. (Parallel molding process of the foamable synthetic resin material 30).

  In the sandwich panel manufacturing apparatus and the manufacturing method thereof according to the present invention, a frame for filling the foamable synthetic resin material is unnecessary, and the bonding of the top paper, the bottom paper, and the side paper to the foamable synthetic resin material is close and strong. As a result, the overall rigidity is enhanced and the appearance is improved to prevent heat from flowing in and out.
