Description

  The present invention relates to a method and an apparatus for manufacturing a tile unit in which a plurality of tiles arranged at a predetermined joint interval are connected by a bridge piece made of synthetic resin.

  As shown in FIG. 17, each of a plurality of tiles T, T... Aligned at a predetermined joint interval (hereinafter referred to as an aggregate of such tiles T, T...) Is made of a synthetic resin. A tile unit U connected by a bridge piece B is known. A conventional method for manufacturing the tile unit U will be described with reference to FIGS. First, a synthetic resin b (for example, thermosetting resin such as polyvinyl chloride) as a material of the bridge piece B is dropped at the bridge piece arrangement point on the flat cradle A with the nozzle N, and the tile group is placed thereon. Then, the back surface of the tile group and the synthetic resin b are brought into close contact with each other, and the curing process of the synthetic resin b (for example, heating for a predetermined time if the synthetic resin b is a thermosetting resin) is performed.

The conventional manufacturing method (hereinafter simply referred to as a nozzle dropping method) has the following problems.
(1) Since the soft synthetic resin b before being cured is sandwiched between the cradle A and the tile T and crushed, the portion (see S in FIG. 17) becomes thin and the adhesive strength to the tile T is insufficient.
(2) Since the synthetic resin b sandwiched and crushed between the cradle A and the tile T escapes into the gap between the joints, a bowl-shaped bridge piece B having a large swelled center is formed. Usually, in the construction method using the tile unit U, the bridge piece B of the tile unit U is often cut and adjusted at the final stage, but the bridge piece B becomes thick at the joint portion as described above. If it is, it is difficult to cut and the separated bridge pieces B do not overlap with each other smartly, so adjustment to reduce the joint width becomes difficult. Further, the bridge piece B swelled in a bowl shape sometimes protrudes to the surface beyond the thickness of the tile T, so that the appearance is very bad.
(3) The end of the bridge piece B may enter the peeling prevention groove V formed on the back surface of the tile T, and the peeling prevention effect of the tile T itself is reduced.
(4) Since the tile group floats from the cradle A and is supported by the synthetic resin b, the tile group becomes unstable, and there is a possibility that the arrangement of tiles may be out of order in the process of moving to the next process.
(5) Nozzles N are required as many as the number of bridge pieces B. However, since the unit price per nozzle N is high, the cost is high. Moreover, if the dimensions and arrangement of the tiles T of the tile unit U are changed, it is necessary to change the arrangement of the nozzles N in accordance with the change, and this is not suitable for the production of a small quantity.
(6) Since the shape of the bridge piece B is not constant, the commercial value of the tile unit U is low.

As shown in FIGS. 15 and 16, the present applicant paying attention to the above problem of the nozzle dripping method,
(1) A mold recess 100 for forming a bridge piece B is formed on a cradle 1 on which a tile group is placed, and a mold sheet 3 provided with a cutout mold hole 2 that matches the mold recess 100 is stacked on the cradle 1 (FIG. 15). (Refer to the right half.)
(2) Filling the cutout mold hole 2 from the upper surface side of the mold sheet 3 with a synthetic resin b in a fluid state as a material of the bridge piece B (see the left half of FIG. 15).
(3) The mold sheet 3 is removed and the upper part of the synthetic resin b is protruded higher than the upper surface of the cradle 1 (see the right half of FIG. 16).
(4) By placing the tile group face up on the upper surface of the cradle 1, the back surface of the tile group is brought into close contact with the synthetic resin b (see the left half of FIG. 16).
(5) The bridge piece B is formed by executing the curing process of the synthetic resin b in that state.
We have filed a patent application (Japanese Patent Application No. 10-100586) for a method of manufacturing the tile unit NU.

  As a result, the tile unit manufacturing method according to the prior application has achieved the intended result, but as a result of further testing and research, it can be implemented without the mold recess 100 of the cradle 1. I found the fact that there is. Based on this knowledge, the applicant filed a patent application of Japanese Patent Application No. 11-95663.

The gist of the patent application is “a tile unit manufacturing method in which each tile of a tile group is connected by a synthetic resin bridge piece to form a tile unit, the cradle for placing the tile group, and the bridge piece. Using a mold sheet having a cut-out mold hole in the shape of a bridge piece according to the arrangement, and a filling means for filling the cut-out mold hole with a synthetic resin in a fluid state, the following (1) to (4) The manufacturing method of the tile unit which comprises the requirements of.
(1) A mold sheet is stacked on the cradle and filled with a synthetic resin in a fluidized state as a material of a bridge piece from the upper surface side of the mold sheet into a cut mold hole.
(2) Remove the mold sheet and directly place the synthetic resin in the cutout mold hole on the upper surface of the cradle.
(3) The back surface of the tile group is brought into close contact with the synthetic resin by placing the tile group on the upper surface of the cradle with the front of the tile group facing upward.
(4) In that state, the synthetic resin is cured to form a bridge piece. "
That's it.

  According to the above manufacturing method, since the synthetic resin is directly mounted on the upper surface of the cradle, it is not necessary to match the mold recess 100 of the cradle 1 and the cutout mold hole 2 of the mold sheet 3 in comparison with the prior invention. Moreover, since the bridge piece B can be easily peeled off from the cradle 1, the productivity is improved. Further, since it is not necessary to form the mold recess 100 in the cradle 1, the manufacturing cost of the cradle 1 is greatly reduced. be able to.

  On the other hand, in contrast with the conventional nozzle dripping method, the nozzle dripping method is such that the central portion of the synthetic resin b dripped from the nozzle N (see symbol W in FIG. 18 (a)) has a mountain height, which is a joint portion. In contrast to causing the phenomenon of thickening, the present invention makes it difficult to generate a thickening phenomenon at the joint because the synthetic resin can be molded uniformly and accurately through the cut-out mold holes of the mold sheet. Further, since the expensive nozzle N is not required, the cost is low, and it is only necessary to change the mold sheet in response to the change in the arrangement and dimensions of the tiles of the tile unit.

  Further, the second invention is “a method of manufacturing a tile unit in which a meat stealing portion for receiving a synthetic resin directly placed on the upper surface of the cradle is formed at a bridge piece fixing portion of each tile of the tile group”. . As a result, the amount of the synthetic resin crushed by the tile is drastically reduced, which makes it more difficult for the joint portion to rise.

  Further, the third aspect of the present invention is that “a support member that is set at a position higher than the upper surface of the cradle is formed so as to be detachable or retractable on the cradle, and the set position of the tile group by the support member is set on the synthetic resin. The tile unit manufacturing method is set to be lower than the wall thickness, and the support member is placed on the receiving base between the time when the mold sheet is removed and the time when the tile group is mounted. In this way, the joints are less likely to swell, as in the second aspect, without any processing on the tile itself.

  The effects of Embodiments 1 to 3 and the invention of Japanese Patent Application No. 11-95663 are as described in the following paragraph numbers “0012” to “0040”.

Embodiment 1 of the Invention
Embodiment 1 of the present invention will be described below with reference to FIGS. 1 is an exploded perspective view showing the main part of the tile unit manufacturing apparatus, FIG. 2 is a rear view of the tile unit, FIG. 3 is a longitudinal sectional view of the tile unit, and FIG. 4 is a longitudinal sectional view of the cradle and the mold plate. 5 is a longitudinal sectional view showing a state in which the cutout mold hole of the mold plate is filled with synthetic resin, FIG. 6 is a longitudinal sectional view of the cradle showing a state in which the mold plate is removed from FIG. 5, and FIG. It is a longitudinal cross-sectional view which shows the state which mounted the tile group.

  First, a finished product of the tile unit NU will be described. As shown in FIGS. 2 and 3, the tile unit NU is formed by connecting the tiles T, T... Constituting the tile group with the bridge pieces B, B. The bridge piece B has an elastic band structure formed of, for example, polyvinyl chloride, which is a thermosetting resin, and is attached to a portion other than the peeling prevention groove V of the tile T on the back side of the tile T. ... connecting each other. As described above, the tile group is an aggregate of a plurality of tiles T, T... Aligned with a predetermined joint interval.

  Next, a method for manufacturing the tile unit NU will be described. In the manufacturing method of the present invention, as shown in FIG. 1, the cradle 1 for placing the tile group, the mold sheet 3 having the cutout mold hole 2, and the synthetic resin b in a fluid state are filled in the cutout mold hole 2. The tile unit manufacturing apparatus having the filling means 4 as a main component is used.

  As shown in FIG. 1, the cradle 1 is a flat plate made of metal having a sufficient area for mounting the tile unit NU, and has a flat upper surface for releasing performance of a fluororesin or a silicone resin. An excellent synthetic resin film is formed. This cradle 1 slides on a roller conveyor (not shown), for example, and moves appropriately between processes.

  The mold sheet 3 is provided with cut-out mold holes 2, 2... In the shape of the bridge piece B according to the arrangement of the bridge piece B on a stainless steel plate having a thickness of about 1 mm to 1.5 mm. One end is pivotally attached to a fixing member such as a support frame of a roller conveyor, and is attached so as to be swingable, or is attached so as to move up and down at a fixed position by an appropriate lifting device.

  The filling means 4 includes a pair of rubber spatula members 40, 40 that are in sliding contact with the upper surface of the mold sheet 3, and a synthetic resin b in a fluid state that serves as a material for the bridge piece B between the spatula members 40, 40. And a driving means (not shown) for reciprocating the spatula members 40 and 40 on the mold sheet 3.

  First, the cradle 1 that moves on the roller conveyor is stopped at a predetermined position corresponding to the mold sheet 3 as shown in FIG. 4, and the mold sheet 3 is stacked on the cradle 1. Next, as shown in FIG. 5, the spatula member 40, 40 is slid back and forth on the mold sheet 3 in a state in which the flowing synthetic resin b is filled between the spatula members 40, 40 of the filling means 4. Then, the synthetic resin b which is the material of the bridge piece B is filled in the cutout mold holes 2, 2... With a uniform thickness. As shown in the drawing, the spatula members 40, 40 are made into a set, so that the synthetic resin b can be reliably filled in the forward stroke and the backward stroke. The synthetic resin b is a thermosetting resin (polyvinyl chloride) and has fluidity at room temperature. Next, the mold sheet 3 is removed from the cradle 1 and the synthetic resin b in the cutout mold hole 2 is directly placed on the upper surface of the cradle 1 as shown in FIG.

  On the other hand, tiles T, T,... Are arranged in another place to form a tile group, which is sucked and transported and stopped above the cradle 1 as shown by a two-dot chain line in FIG. 6, and the tile group is lowered as it is. As shown in FIG. 7, the table is placed on the upper surface of the cradle 1 with the front side facing up. If it does so, the back surface of tile T, T ... will closely_contact | adhere to the synthetic resin b of the receiving stand 1. FIG. Although the thickness of the synthetic resin b is exaggerated for easy understanding, the thickness of the tile T is actually 7 mm, whereas the thickness of the synthetic resin b is very thin, 1 mm to 1.5 mm.

  Next, the curing process of the synthetic resin b is executed in the state shown in FIG. In the embodiment, since the synthetic resin b is polyvinyl chloride as a thermosetting resin, the entire cradle 1 may be transported and placed in a heating furnace and heated at 140 ° C. for 15 minutes. By doing so, the synthetic resin b is hardened to form a bridge piece B, and at the same time, the bridge piece B is attached to the back surface of the tile T to connect the tiles T, T. When a thermosetting resin is used as the material of the bridge piece B, there is an advantage that the bridge piece B does not peel off even if the completed tile unit NU is left under the hot sun and the temperature rises.

  In addition, naturally the hardening process of the said synthetic resin b changes with kinds of the synthetic resin b. For example, when a photosensitive resin is used as the material of the bridge piece B, the synthetic resin b is cured by irradiating light (ultraviolet rays).

  Next, the tile group is removed from the cradle 1 by suction or manually. Then, the bridge piece B is attached to the tile group side and peeled off from the cradle 1. At this time, if the synthetic resin film having excellent mold release performance is formed on the cradle 1 as described above, the peeling work of the bridge piece B can be performed very smoothly.

Embodiment 2 of the Invention
FIGS. 8 and 9 show Embodiment 2 of the invention, and both figures are enlarged sectional views of essential parts showing a state in which tiles are placed on a cradle.

  The manufacturing apparatus of the second embodiment is the same as that of the first embodiment, but is characterized in that the meat stealing portions 50 and 51 are formed at the bridge piece B fixing portions of the tiles T, T. Specifically, a chamfered meat stealing portion 50 is formed around the back surface of the tile T as shown in FIG. 8, or a stepped meat stealing portion 51 is formed around the back surface of the tile T as shown in FIG. . These meat stealing portions 50 and 51 receive the synthetic resin b placed directly on the upper surface of the cradle 1. With the tile group placed on the upper surface of the cradle 1, as shown in FIGS. The abdominal surfaces of the portions 50 and 51 and the synthetic resin b are securely adhered. By providing the meat stealing portions 50 and 51, the amount of the synthetic resin b to be crushed by the tile T is drastically reduced, so that the rise to the joint portion is suppressed in the same manner as in the prior invention. The meat stealing portions 50 and 51 do not have to be formed around the entire back surface of the tile T, and may be partially provided in accordance with the position of the bridge piece B.

Embodiment 3 of the Invention
10 to 13 show Embodiment 3 of the invention. FIGS. 10 and 11 are partially cutaway plan views showing a state in which tile groups are placed on a cradle, and FIG. 12 is an exploded perspective view showing a support member. FIG. 13 is an enlarged sectional view taken along line XX of FIG.

  The manufacturing apparatus of the third embodiment is characterized in that the support member 6 is detachably mounted on the upper surface of the cradle 1. That is, the support member 6 is formed by forming a tile seat 61 at the corner portion of the prismatic body 60 as shown in FIG. 12 and directly placing the height of the tile seat 61 on the upper surface of the cradle 1. The joint pin 62 is set to be lower than the thickness of the resin b and protrudes from the bottom surface of the prismatic body 60. The joint pin 62 is loosely fitted into the receiving hole 63 formed on the receiving base 1 side.

  Thus, in this manufacturing apparatus, the mold sheet 3 is stacked on the upper surface of the cradle 1 in a flat state before the supporting member 6 is attached, and the synthetic resin b is filled with the filling means 4, and the mold sheet 3 is removed and the cutting die is removed. The synthetic resin b in the hole 2 is directly placed on the receiving base 1, and then the joint pin 62 is fitted to the receiving base 1 and attached to the receiving base 1 as shown in FIG. A tile group is placed on the tile seat 61. Since the height of the tile seat portion 61 of the support member 6 is set lower than the thickness of the synthetic resin b as described above, the synthetic resin b on the back surface of the tile T in a set state on the tile seat portion 61. Is in close contact.

  And after performing the hardening process of the synthetic resin b in that state, the tile group is removed from the cradle 1 and the support member 6 is also detached from the cradle 1 and returns to the first step.

  Further, the support member 6 of the third embodiment may be formed in a single plate shape as shown in FIG. 11 in addition to the case where a plurality of separate parts are combined as described above. That is, the supporting member 6 is formed by punching a window hole 65 opened at a position corresponding to the synthetic resin b and larger than that on a plate 64 having a size substantially equal to that of the cradle 1, and further, a tile T on the plate 64. The partition ribs 66 are projected vertically and horizontally in accordance with the arrangement. This partition rib 66 mainly has a positioning function for the tile T, but also has a reinforcing function for preventing the plate 64 from warping.

  The thickness of the plate 64 is smaller than the thickness of the synthetic resin b. For example, if the thickness of the synthetic resin b is 1.5 mm, the plate thickness is set to 1 mm. A small amount of the synthetic resin b protrudes from the window hole 65 in the installed state.

  Thus, in this manufacturing apparatus, the mold sheet 3 is stacked on the upper surface of the cradle 1 in a flat state before the supporting member 6 is attached, and the synthetic resin b is filled with the filling means 4, and the mold sheet 3 is removed and the cut-out mold is removed. The synthetic resin b in the hole 2 is directly placed on the receiving base 1, and then the supporting member 6 is placed on the receiving base 1. At this time, if a positioning means 67 (see FIG. 11) such as a combination of a boss and a boss hole is provided on the support member 6 and the cradle 1, the positioning can be performed accurately, so that it is synthesized with the window hole 65 of the plate 64. The resin b is surely faced. Although not shown, an appropriate clamping means may be provided to temporarily fix the support member 6 to the receiving table 1.

  Then, when the tile group conveyed in the aligned state is placed on the support member 6, the tiles T are accurately aligned by being guided by the partition rib 66, and the thickness of the support member 6 is larger than the thickness of the synthetic resin b. Since it is small, the back surface of the tile T and the synthetic resin b adhere closely. After executing the curing process of the synthetic resin b in this state, the tile group is removed from the cradle 1. As a feature of the present embodiment, since the tile unit NU is entirely placed on the support member 6, the bridge piece B is automatically peeled from the cradle 1 by lifting the plate 64.

  According to the tile unit manufacturing apparatus and the manufacturing method of the third embodiment, the amount of the synthetic resin b crushed by the tile T is drastically reduced as in the above-described prior invention, so that there is almost no rise to the joint portion. Further, if the support member 6 has a function of positioning the tiles T such as the tile seat 61 and the partition rib 66 as in the third embodiment, the tile T is firmly fixed on the cradle 1. Even if the tile group is moved between processes while being placed on the cradle 1, the arrangement of the tiles T does not go wrong.

  As mentioned above, although this invention was demonstrated by Embodiment 1-3, of course, this invention is not limited to said each embodiment. For example, in Embodiments 1 to 3, a stainless steel plate is used for the mold sheet 3, but the mold sheet 3 may be any material such as synthetic resin, cloth, wood, or ceramic. In FIGS. 10 and 12 of the third embodiment, an attachment / detachment method is adopted in which the support member 6 is fitted into the cradle 1. For example, a vertical hole is formed in the cradle 1, and the support member 6 is inserted into the vertical hole. The head of the support member 6 may be moved up and down on the cradle 1 by moving up and down. In this case, the synthetic resin b is directly mounted in a state where the support member 6 is lowered, and the support member 6 is projected before the tile T is mounted.

  Further, the cradle 1 of the first to third embodiments has a completely flat surface, but the entire surface of the cradle 1 has striped or lattice-shaped shallow grooves, or an infinite number of hemispherical depressions on the entire surface. You may make it provide in. Since these shallow grooves and depressions are irrelevant to the cutout mold hole 2, they are different from the mold recess 100 of the prior invention.

  In addition, the mold sheet 3 of the first to third embodiments has a flat plate shape. For example, as shown in FIG. 14, the mold sheet 3 is formed in a circular drum shape and rotated, and the cradle 1 is linearly synchronized with the rotation. You may make it move to. In this case, the filling means 4 is incorporated in the mold sheet 3 in a non-rotating structure, and the spatula member 40 is brought into sliding contact with the inner peripheral surface of the mold sheet 3.

[The invention's effect]
In the present invention, since the synthetic resin is directly mounted on the upper surface of the cradle, first, in comparison with the prior invention, there is no inconvenience of matching the mold concave portion of the cradle with the cutout hole of the mold sheet. Productivity is improved, and it is not necessary to form a mold recess in the cradle, so that there is an advantage that the manufacturing cost of the cradle can be greatly reduced.

On the other hand, in contrast with the conventional nozzle dripping method,
(1) Although the nozzle dripping method caused a phenomenon in which the central portion of the synthetic resin b dripped from the nozzle N (see symbol W in FIG. 18 (a)) had a mountain height, which caused a thickening in the joint portion. On the other hand, in the present invention, since the synthetic resin can be uniformly and accurately molded in the cut-out mold hole of the mold sheet, the phenomenon that the thickening at the joint portion hardly occurs,
(2) Since the expensive nozzle N is not required, the cost is much lower, and it is only necessary to change the mold sheet in response to a change in the tile arrangement and dimensions of the tile unit. Applicable,
(3) Because the shape of the bridge piece is accurate and the finish is beautiful, the product value increases.
To demonstrate the superiority.

  In addition, if the meat stealing portion for receiving the synthetic resin directly placed on the upper surface of the cradle is formed at the bridge piece fixing portion of each tile of the tile group, the amount of the synthetic resin to be crushed by the tile is drastically reduced. As in the prior application invention, the rise phenomenon of the joint portion is unlikely to occur.

  Further, the support member for setting the tile group at a position higher than the upper surface of the receiving table is formed on the receiving table so as to be detachable or retractable, and the setting position of the tile group by the support member is set lower than the thickness of the synthetic resin. If the support member is installed on the pedestal after the mold sheet is removed and the tile group is placed, the amount of synthetic resin to be crushed by the tile is drastically reduced. Swelling phenomenon at joints is unlikely to occur.

  The above is the effects of the first to third embodiments of the patent application and the effects of the invention. As a result of further research and development by the present applicant, further cost can be increased by applying and developing the invention described in the earlier patent application. Reached a method and apparatus that would allow down.

A tile unit manufacturing method in which a plurality of tiles arranged at predetermined joint intervals (hereinafter referred to as a group of such tiles) are connected by a synthetic resin bridge piece to form a tile unit. A cradle for placing the tile group, a mold sheet having a cut-out mold hole penetrated in accordance with the arrangement of the bridge pieces, and a filling means for filling the cut-out mold hole with a synthetic resin in a fluid state And forming a joint frame that rises at the joint spacing portion of the tile group at a position corresponding to at least the bridge piece of the cradle, and further comprises the following requirements (1) to (4): A method for manufacturing a tile unit is provided.
(1) Set the tile group face down on the cradle.
(2) Filling with a synthetic resin in a fluidized state as a bridge piece material from the upper surface side of the mold sheet to the cut-out mold hole in a state where the mold sheet is overlaid on the back surface of the tile group set on the cradle Fill.
(3) Remove the mold sheet and allow the synthetic resin in the cutout mold hole to adhere to the back surface of the tile group.
(4) The synthetic resin is cured in this state to form a bridge piece.

  A tile unit manufacturing apparatus that connects tiles of a tile group with a bridge piece made of a synthetic resin to form a tile unit, and a cradle on which the tile group is placed and penetrating in accordance with the arrangement of the bridge piece. A mold sheet having a cut-out mold hole, and a filling means for filling the cut-out mold hole with a synthetic resin in a fluid state, and a portion of the tile group at a position corresponding to at least a bridge piece of the cradle The tile group is set face down on the cradle, the mold sheet is overlaid on the back surface of the tile group, and bridged from the upper surface side of the mold sheet to the cut mold hole. Fill the fluidized synthetic resin that will be the raw material of the piece with the filling means, remove the mold sheet, adhere the synthetic resin in the cutout mold hole to the back of the tile group, and cure the synthetic resin in that state Providing an apparatus for manufacturing tile unit which is adapted to perform a physical form a bridge piece.

  According to the above method and apparatus, the synthetic resin as the material of the bridge piece can be directly and surely applied to the back surface of the tile group with a mold sheet, and the synthetic resin is cured. Since the synthetic resin is exposed on the tile group facing down, the efficiency of the curing process is good.

  The present invention is an application and development of the conventional nozzle dropping method in which a cutout hole in a mold sheet is filled with a synthetic resin to form a bridge piece accurately and reliably, and a cradle with a tile group facing down. Since the synthetic resin is directly applied to the back of the tile group with the mold sheet and the curing process of the synthetic resin is executed in that state, the bridge sheet can be accurately and reliably formed by the mold sheet. In addition, since the synthetic resin is exposed to the outside of the upper surface of the tile group facing backward in the state where the curing process of the synthetic resin is executed, the efficiency of the curing process is improved. Compared to the above-mentioned application, in which this effect is applied to a means in which a synthetic resin is applied to a cradle and a tile group is placed thereon, in a sandwich state in which the synthetic resin is sandwiched between the cradle and the tile group, the synthetic resin Even if it is heated, for example, even if it is heated, it becomes difficult for heat to be transmitted to the synthetic resin, and it takes time to cure, but when the synthetic resin is exposed on the tile group as in the present invention, it is directly applied to the synthetic resin. Since heat is transmitted, curing is completed at a low temperature or in a short time. That is, fuel consumption can be saved and productivity can be improved accordingly, and the tile unit after the curing process can be cooled in a short time, so that the handling after the curing process becomes easy.

  In addition, since the joint frame is formed on the cradle and tiles are set in the cradle, there is no risk of the tiles shifting laterally on the cradle, and the bridge piece is cured as it is, so the finish accuracy of the tile unit is improved. It has the effect of improving.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 19 is an exploded perspective view showing the main part of the tile unit manufacturing apparatus, FIG. 20 is a longitudinal sectional view of the main part showing the state before placing the tile group on the cradle, and FIG. 21 shows the mold plate in the tile group. FIG. 22 is a longitudinal sectional view of the main part showing the loaded state, FIG. 22 is a longitudinal sectional view of the principal part of the cradle and the tile group showing the state where the mold plate is removed after filling with the synthetic resin, and FIGS. It is a partial expanded sectional view of the base and tile group which show the state which removed the plate.

  The finished product of the tile unit NU to be manufactured is the same as described above with reference to FIGS.

  Next, a method for manufacturing the tile unit NU will be described. In the manufacturing method of the present invention, as shown in FIG. 19, the cradle 1 on which the tile group is placed, the mold sheet 3 having the cut mold hole 2, and the synthetic resin b in the fluidized state are filled into the cut mold hole 2. The tile unit manufacturing apparatus having the filling means 4 as a main component is used.

  As shown in FIG. 19, the cradle 1 projects a joint frame 1M that rises at the joint spacing portion of the tile unit NU on the upper surface of a flat metal plate having a sufficient area for mounting the tile unit NU. Set up. The height of the joint frame 1M may be substantially the same as the thickness of the tile T, slightly lower than the thickness of the tile T, or slightly higher than the thickness of the tile T. Moreover, it is good to form the layer 42a of the raw material excellent in the peelability of the synthetic resin b in the joint frame 1M at least at the top part, and it is good to form the layer 42b excellent in cushioning properties in both sides. The illustrated joint frame 1M is formed with fluororesin layers 42a and 42b having both peelability and cushioning properties as shown in FIG. As shown in FIGS. 23A to 23D, the cross-sectional shape of the joint frame 1M may be any of a square, a trapezoid, a bowl, a circle, or any other.

  When the joint frame 1M is a quadrangle in FIG. 23A, the lateral width is set slightly smaller than the joint spacing (for example, 4 to 4.5 mm when the joint spacing is 5 mm), and the width of FIG. 23B is set. In the case of a trapezoidal shape, the upper side is set slightly smaller than the joint interval and the lower side is set to be equal to or slightly larger than the joint interval, and the joint frame 1M is formed as a saddle shape shown in FIG. 23 (c) or FIG. 23 (d). In the case of a circle, the diameter should be set to be approximately equal to the joint spacing. By doing so, it becomes easy to cope with variations in tile shape. The illustrated joint frame 1M surrounds the entire circumference of the tile T. However, the present invention is not limited to this. The joint frame 1M only needs to be at least at a position corresponding to the bridge piece B.

  The mold sheet 3 is provided with cut-out mold holes 2, 2... In the shape of the bridge piece B in accordance with the arrangement of the bridge piece B on a stainless steel plate having a thickness of about 0.3 mm to 1.5 mm. , One end is pivotally attached to a fixing member such as a support frame of the roller conveyor, and is attached so as to be swingable, or is attached so as to move up and down at a fixed position by an appropriate lifting device. In addition, when making the thickness of the type | mold sheet | seat 3 thin, it is good to make the joint frame 1M lower than the back surface of the tile T (refer FIG.23 (b)). The reason is that when the mold sheet 3 is made thinner, the bridge piece B is naturally made thinner and the adhesive strength with the tile T is lowered. However, by lowering the joint frame 1M, the synthetic resin b enters the joint spacing of the tile group, and the tile This is because the synthetic resin b also adheres to the side surface (rib surface) of T and the adhesive strength is improved.

  The filling means 4 includes a pair of rubber spatula members 40, 40 that are in sliding contact with the upper surface of the mold sheet 3, and a synthetic resin b in a fluid state that serves as a material for the bridge piece B between the spatula members 40, 40. And a driving means (not shown) for reciprocating the spatula members 40 and 40 on the mold sheet 3.

  First, the cradle 1 that moves on a roller conveyor (not shown) is first stopped at a predetermined position corresponding to the mold sheet 3 as shown in FIG. On the other hand, tiles T, T,... Are arranged face down in another place to form a tile group, which is sucked and transported as shown by a one-dot chain line in FIG. To do. Thereby, the joint frame 1M fits into the joint interval of the tile group. Next, as shown in FIG. 21, the mold sheet 3 is stacked on the back surface of the tile group, and the spatula members 40, 40 are filled with the fluid synthetic resin b between the spatula members 40, 40 of the filling means 4. Is reciprocated on the mold sheet 3 once. Then, the cutout mold holes 2, 2... Are filled with the synthetic resin b, which is the material of the bridge piece B, in a scraped state. The synthetic resin b is a thermosetting resin (polyvinyl chloride) and has fluidity at room temperature, but its viscosity should be set low. By doing so, even if there is a gap between the joint frame 1M of the cradle 1 and the tile T as shown in FIG. 23B, the synthetic resin b is difficult to enter the gap.

  Next, the mold sheet 3 is removed. Then, as shown in FIG. 22, the synthetic resin b in the cutout hole 2 remains on the back surface of the tile group. Since the cutout mold hole 2 of the mold sheet 3 is provided in accordance with the arrangement of the bridge pieces B, the synthetic resin b is in a mode of connecting adjacent tiles T, T... Across the joint frame 1M. If the synthetic resin b is in close contact with the tile T in this state, the curing process of the synthetic resin b is executed as it is. If the synthetic resin b is more firmly adhered to the tile T, the pressing means 43 (FIG. 23) waits until the synthetic resin b is slightly cured and a thin skin is stretched on the surface. The synthetic resin b may be pressed against the tile group in (a) dash-double-dot line). If the synthetic resin b is pressed after a thin skin is stretched, it is convenient that the synthetic resin b does not easily adhere to the pressing means 43. Further, if irregularities such as countless small protrusions and ridges are formed on the pressing surface 44 of the pressing means 43, irregularities such as dimples and knurls are engraved on the back surface of the bridge piece B. In addition, it is possible to obtain an effect that the bridge piece B is easy to adjust and is difficult to peel off.

  Since the synthetic resin b is polyvinyl chloride, which is a thermosetting resin, the synthetic resin b is cured by putting the cradle 1 in a heating furnace. The heating condition at that time is that the synthetic resin b is exposed outside the cradle 1, so if the same synthetic resin b as in the previous patent application is used, the temperature should be lowered from 140 ° C. for 15 minutes. Alternatively, the heating time can be shortened.

  By executing the above curing process, the synthetic resin b is cured to form a bridge piece B, and at the same time, the bridge piece B is attached to the back surface of the tile T to connect the tiles T, T. When a thermosetting resin is used as the material of the bridge piece B, there is an advantage that the bridge piece B does not peel off even if the completed tile NU is left under the sun and the temperature rises.

  In addition, naturally the hardening process of the said synthetic resin b changes with kinds of the synthetic resin b. For example, when a photosensitive resin is used as the material of the bridge piece B, the synthetic resin b is cured by irradiating light (ultraviolet rays).

  Next, the tile group is removed from the cradle 1 by suction or manually. Then, the bridge piece B is attached to the tile group side and peeled off from the joint frame 1M of the cradle 1. At this time, if the synthetic resin layers 42a and 42b having excellent release performance are formed on the joint frame 1M as described above, the peeling work of the bridge piece B can be performed very smoothly.

  Although the present invention has been described above with reference to the embodiment, it is needless to say that the present invention is not limited to the above embodiment. For example, also in the present invention, the mold sheet 3 is formed into a circular drum shape as shown in FIG. 14, or the meat stealing portions 50 and 51 are formed at the fixing portion of the bridge piece B of the tile T as shown in FIGS.
