DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic view showing the concept of the present invention. As shown in FIG. 2, the hollow body resin plate 1 is formed with a large number of grooves 6 partitioned by a large number of webs 4 between the front wall 2 and the back wall 3. 1 is intermittently sent vertically in the direction of arrow 9 in FIG. A filling nozzle device 10 is arranged below the conveying path of the hollow body resin plate 1 so as to be driven up and down, and the filler melted by the pump 12 from the melting tank 11 of the filler 8 is supplied to the filling nozzle device. It has become. Reference numeral 13 denotes a control valve composed of an electromagnetic valve or the like, which controls the amount of filler supplied to the filling nozzle device 10, that is, the filling amount. The filling nozzle of the present invention can fill an arbitrary position inside the opening groove away from the mouthpiece 5 by an arbitrary length, and the nozzle port 14 of the filling nozzle device 10 has various sizes depending on the application. For example, as shown in FIG. 2A, when filling a position far from the mouth of the opening groove, the tip of the nozzle opening 14 enters the opening groove and reaches the filling start position. Use a long nozzle opening.
[0011]
In the filling nozzle device 10, the nozzle port 14 is driven to move up and down at least between the filling start position and the position away from the wooden mouth 5, and the groove 6 to be filled next is filled in after the filling is completed at a predetermined position and the nozzle opening is separated from the wooden mouth. Until the position reaches the upper position of the nozzle opening, the hollow resin plate is fed in a predetermined amount in the direction of the arrow. FIG. 1 shows a case where a filler is filled only at the end of the groove for closing the mouth, in which case the nozzle mouth 14 is driven up and down by the first displacement means so as to reach the position of the mouth, and the hollow body resin plate Is intermittently fed by one groove pitch by the second displacement means. The filling amount controls the pump 12 and the control valve 13 by a timer according to the filling length into the groove.
[0012]
Therefore, according to the present invention, the filler can be filled in an arbitrary position of the groove of the hollow resin plate as necessary. FIG. 2 is a schematic diagram when the filling position is arbitrarily changed, and shows a hatched portion where the filler is filled, and (a) the section is filled up to a predetermined distance from the mouth, (B) When the section is filled over the entire length of the groove, (c) and (d) When the section is filled at a predetermined distance away from the mouth and at a predetermined distance in the middle, Only the case of filling is shown.
[0013]
The filler used in the present invention includes at least a synthetic resin having a low temperature melting and better fluidity than the synthetic resin forming the hollow resin plate body, and has good affinity with the material of the hollow resin plate after solidification. Furthermore, a material that can maintain a moderate frictional force against nailing or the like is preferable. And it is desirable that it is a material that can be melted and recycled together with the material of the hollow resin plate. As a material satisfying such conditions, for example, a mixture of APP resin and calcium carbonate can be suitably applied. The filler may be only the low-melting resin, but may be a mixture of the low-melting resin and other inorganic substances such as calcium carbonate or organic substances such as wood powder.
[0014]
By using a synthetic resin contained in the filler having a melting temperature lower than at least the melting temperature of the material of the hollow resin plate, the hollow resin plate is prevented from being thermally deformed by the filler during filling. And because the flowability of the molten resin is good, it can be filled without creating a gap in the groove, it adheres closely to the hollow resin plate, does not fall off after solidification, and in the case of clogging the mouth completely It is possible to completely prevent rainwater, concrete, dust, or the like from entering the groove from the mouth. In addition, even if the filler is left unfilled, the end face of the end is good, there is no need for finishing cuts, and the work process can be shortened.
[0015]
As described above, according to the present invention, it is possible to automatically fill the hollow resin plate with a filler at an arbitrary position of the groove, and to obtain the required strength of the hollow resin plate depending on the application. Therefore, it is possible to obtain a hollow body resin plate that can be used not only as a concrete mold but also as a substitute for a shelf board, a floor board, or a plywood board, for example. Moreover, for example, a hollow resin plate suitable for cardboard, a line pallet for paper containers, a top plate, and the like can be obtained.
[0016]
【Example】
3 and 4 show an embodiment of the filler filling device for a hollow resin plate according to the present invention.
In the filler filling device 20 of the present embodiment, the second displacing means is configured as the following hollow body feeding device so that the hollow body resin plate is clamped in an upright state and intermittently conveyed to the nozzle device. It is. In the figure, reference numeral 21 denotes a screw rod such as a ball screw that is rotationally driven by a motor 22, and both ends thereof are rotatably supported by a frame 23. A pair of clamps 24 and 25 are screwed onto the screw rod, and both ends of the hollow resin plate are clamped and held by the clamps in an upright state. When the screw rod is rotated by the motor in this state, a clamp screwed to the screw rod is sent, and the hollow resin plate is displaced by a predetermined pitch.
[0017]
On the other hand, a nozzle device 27 having a plurality of nozzle ports 26 in series in the feed direction of the hollow body resin plate below the conveyance path of the hollow body resin plate is appropriately driven by a cylinder device or the like with respect to the frame 23. It is arranged to be movable up and down by the device. A control valve and a pipe joint are arranged in connection with the nozzle device, and a pipe for supplying a molten filler is connected. Therefore, in the present embodiment, the first displacing means is configured as a vertical drive device that moves the nozzle device 27 up and down.
[0018]
The filler filling device of the present embodiment is configured as described above, and is set in advance by clamping the hollow resin plate 1 with a pair of clamps 24 and 25 and operating a button on a control panel (not shown). In accordance with the programmed program, the motor 22 operates to intermittently feed the hollow resin plate. On the other hand, the nozzle device rises when the groove to be filled with the filler reaches above the nozzle, and fills the predetermined position in the groove with the molten filler from the nozzle opening. The vertical movement of the nozzle is controlled so that the nozzle tip reaches a predetermined height position by driving for a preset time, whereby the filler can be filled at an arbitrary position. Further, in this embodiment, since the filling of the filler is performed from below with the hollow resin plate standing upright, the molten filler can be reliably filled into a predetermined position even if the fluidity of the filler is high. . The filler can be filled even when the hollow resin plate is placed sideways, but in that case, if it is a melt-filler rich in fluidity, it flows into the entire groove, making it difficult to fill only in predetermined positions. . Since the filler is injected from the nozzle and solidifies after a while, it does not flow down even if the hollow resin plate is filled up.
[0019]
Using the above apparatus, the following filler was filled, and the filler was filled in the open end of the hollow resin plate under the following conditions to close the end of the mouth.
Examples Filler APP 20-100%
Calcium carbonate 0-80%
Hollow body resin board material Polypropylene thickness 3-15mm
Filling position Only 30mm or less from the groove open end [0020]
As described above, the thickness of the filler and the hollow resin plate was changed in the above range, and the filler was filled into 10 hollow resin plates. Then, when the end of the filler filled with the filler was inspected after the filler was sufficiently solidified, all the hollow resin plates were filled with the filler completely sealed without any gaps. It had been. And it adhered to the hollow body resin board main body completely, and was not able to be removed from the end. Further, the shape of the groove end face filled with the filler was so good that the finish cut was not necessary. Therefore, it was confirmed in this example that the cuff can be closed well in a short time according to the present invention. Further, a filler was filled in the groove for nailing by a similar method, and after solidifying sufficiently, the nailing was fixed. As a result, the hollow resin plate could be firmly fixed without breaking and without loosening after fixing.
[0021]
As mentioned above, although embodiment and Example of this invention were described, each invention of this application is not restricted to the said embodiment and Example, A various design change is possible within the range of the technical idea. For example, the present invention is not necessarily limited to a thick hollow resin plate, but can also be applied to a thin hollow resin plate. In the above-described embodiment, as a means for displacing the clamp that holds the hollow resin plate, an appropriate means such as a pinion-rack mechanism can be used instead of the screw rod.
[0022]
【The invention's effect】
As described above, according to the present invention, rather than the hollow body resin plate in which the conventional insertion member is inserted by solidification by filling the groove of the hollow body resin plate with a molten filler instead of the conventional insertion member, A hollow resin plate having excellent performance can be easily obtained. And even if there is a variation in the size of the groove of the hollow resin plate, the filler can be in close contact with the groove and filled without gaps, so that the filler does not fall out of the groove after solidification, and the nail It is possible to obtain a hollow resin plate that exhibits high strength for hammering and bolts and screws. Therefore, according to the hollow body resin plate of the present invention, nailing and bolting and screwing can be performed without requiring special metal fittings or the like.
[0023]
Moreover, since the filler can be filled in the groove without any gaps, it becomes possible to completely close the mouth, and even if it is used for a long time in a formwork or the like, concrete, rainwater, dust, etc. do not enter the groove, A hollow resin plate suitable not only as a concrete mold but also as a forming material for containers used in the food field where cleanliness is required can be obtained. In addition, since the filler uses a low-temperature molten resin as a filler rather than the resin of the hollow resin plate body, the surface of the hollow resin plate does not cause sinking even if the molten resin is filled, and deformation is not caused. A good hollow body resin plate can be obtained. Accordingly, it is possible to obtain a hollow resin plate that can be used for a mold or the like that requires a completely flat surface.
[0024]
Since the filler can be selectively filled at any position in the groove by an arbitrary length, only a necessary portion can be filled with the filler, which is economical. In addition, according to the method and apparatus of the present invention, since a filler can be automatically filled, a good hollow body resin plate can be obtained at a lower cost than when a conventional insertion member is fitted. be able to.
