Description

Description: FIELD OF THE INVENTION The present invention relates to a method and an apparatus for jointing tiles, that is, trotting into joint lines between tiles.

(Prior art) Conventionally, when performing tile jointing, a toro, that is, a raw mortar that has been kneaded and adjusted, is placed at an appropriate place along the joint line to be finished, rubbed with a trowel and filled into gaps, and then protrudes. Manual work such as wiping the minute was repeated.

(Problems to be Solved by the Invention) For this reason, it is necessary not only to take time for construction but also to ask a skilled person for work such as toweling or troweling to obtain a good finish. However, due to the difficult times of securing such a large number of skilled technicians, industrial products involving tile wall decoration, especially prefabricated materials, have been stepping down to mass production.

In this regard, even if we deal with the problem of wiping separately, if we can mechanize the filling of the toro to the joint line, the situation will differ greatly, but in the case of tile joints, the viscosity of the toro is generally high, it is not easy to pour, and By simply simulating the hand work, simply raising and leveling will make it difficult to satisfy the filling effect because the joint line is narrow, first, the skirt of the top toro is wide, the yield is poor and uneconomical .

The present invention has been made in order to effectively solve such problems in the conventional jointing of tiles and the problems underlying the same, and the purpose thereof is to aim at a joint line between tiles and to make a toro. An object of the present invention is to provide a method of jointing, which can be packed, has an excellent filling effect, and is suitable for mechanization, and an apparatus for implementing the method, thereby promoting mass production of prefabricated materials.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a method of manufacturing a tile panel comprising:
The joint mortar is finely squeezed and injection-filled while preventing protrusion from the joint portion and leveling the joint surface after joint filling.

And in order to carry out this method, a device for injecting and filling joint mortar into a joint portion of a tile panel, a nozzle portion for injecting and filling joint mortar by bringing a tip into contact with a tile panel surface, and a nozzle portion A jointing device for a tile panel comprising a supply section for supplying joint mortar and a support for supporting the nozzle section above the tile surface of the tile panel.

(Operation) According to the above means, the joint between the tile panels of the tile panel is prevented from protruding from the joint from a line perpendicular to the joint with respect to the joint, and the joint surface after the joint is filled, and the joint is used for the joint. Since the mortar is finely squeezed and injected and filled, the mortar can be effectively aimed at the joint line and fired, and the momentum during injection becomes the impact force when reaching the joint line, and the mortar Pressurize and spread to every corner.

The upper end 20a of the slide pipe 20 is internally screwed.

The slide pipe 20 hangs down directly, penetrates through the gun holder 6, and is connected to the pinch valve 30 below the common base 5 of the sensors 3.

The pinch valve 30 is provided at the upper end 31a of the cylindrical casing 31.
And lower end 31b, reducer-type joint plugs 32, 33

Then, a Teflon dish-shaped end piece 44 as a buffer member that surrounds and protects the lower end 43d of the nozzle small-diameter portion 43a (FIG. 2) and slides on the tile Tij of the wall panel Pw is screwed integrally. A coil spring 45 is contracted between the upper surface 44a and the lower surface of a flange portion 41d formed at the outer periphery of a substantially central portion in the vertical direction of the tip body 41, and the end piece 44 is always urged downward together with the nozzle 43. The material thickness of the piece 44, i.e., the height h, is determined so that the lower end 44c of the end piece center hole 44b, which is to be screwed to the nozzle 43, is ahead of the lower end 43d of the nozzle hole 43b. mortar
In order to prevent Mo from protruding and to level joints, the lower surface 44d of the piece is leveled around the center hole 44b and the outer edge 44d.
Finished in a shape that inclines upward to e, the structure makes it easy to climb on and slide on the tile Tij.

 Here, the operation of the joint filling device Jf will be briefly described.

In order to comprehensively describe the operation directions of the members, an orthogonal spatial coordinate system XYZ will be introduced, in which the forward direction of the pallet truck Tr is the positive direction of the X axis, and the forward direction of the traverse carrier Cr is the positive direction of the Y axis. The direction in which the mortar gun 1 moves upward is defined as the positive direction of the Z axis.

Further, assuming that the tile arrangement of the wall panel Pw is a rectangular array of n columns vertically and m columns horizontally, square tiles having a side length of tmm (including both side half joints) are used as each tile Tij. Assume that it is used.

First, the wall panel Pw as a work is put in a fixed position (that is,
The pallet Pt that has been placed and set (with the corner aligned with the reference point Po)
On the truck Tr waiting at the original position shown in the figure, a vertical
The load is turned on in the direction, and is positioned and held by the pins Pn with respect to the receiving frame Ftr of the truck Tr. At this time, carrier Cr
Is the original position retreated in the −Y direction from the illustrated operating position (that is, the Y coordinates of the four guns 1... Are equal to the Y coordinates of the first to fourth horizontal ground lines Jx1 to Jx4 of the wall panel Pw, respectively. position)
Then, it is waiting while circulating the mortar Mo to the line Lc.

Next, the wire drive mechanism Dw is operated, and the truck Tr
Along the tracks Rt, Rt below the gate frame Fg2.

As a result, the two front and rear rows below the carrier Cr (the plane belonging to the gun center line Cl is set to the reference plane X = 0, and both sides X
= + T / 2 and X = −t / 2, FIG. 1), out of the ten tile sensors 3... Arranged on the + X side of the panel Pw along the + X side vertical edge of the panel Pw. The first to fifth tiles T1
m to T5m are detected, and the detection signal is sent to the control system Sc as a first run start signal and processed.

And the air cylinders 2 and the outer chamber of each pinch valve 30
A corresponding air on / off signal is sent to S2, and a speed control command signal is sent to the step motor Ms of the drive mechanism Cw, respectively, to lower each mortar gun 1 to a predetermined Z coordinate,
The small-diameter portion 43a at the tip of the nozzle 43 is caused to approach and face any of the horizontal seam ground lines Jx1 to Jx4, and the valve 30 is opened to start injection of the mortar Mo. At the same time, the truck Tr is caused to move forward at a constant speed.

In order to explain the movement of the nozzle assembly 40 when reaching this operation state, the normal state of FIG. 2A, that is, the nozzle 43 integral with the end piece 44 is urged fully downward by the spring 45, In a state where the lower end step of the diameter portion 43e is in contact with the lower bottom upper surface of the cap 42, first, the horizontal portion of the end piece lower surface 44d is moved by the downward movement of the gun 1.
Both tiles Tij, Ti ′ adjacent to each other across the corresponding horizontal ground line Jxi
Step C on the upper surface of the j, the stroke difference with the air cylinder 2, the spring 45 is contracted, the nozzle 43 is moved upward, and the pinch valve 30 is opened. Apply downward pressure to the upper end of the portion 43e, and securely hold the tile surface to the lower surface 44d of the end piece, while joining the joint line from the lower end 43d of the nozzle hole 43b.
As shown in FIG. 2 (B), it jumps out to Jxi and goes to every corner. At this time, the center hole 44b of the end piece 44 effectively prevents the injection mortar Mo from protruding. I do. Also, as the truck Tr advances, the lower surface 44d of the end piece 44 made of Teflon slides on the tile surface, and at the same time, the lower end 44c of the center hole 44b is grounded.
Level Js.

Thus, the jointing of the horizontal joint lines Jx1 to Jx4 progresses, and the set of center pairs on the side where the gun 1 is exposed and paid out, that is, the five sensors 3 on the -X side are tiled for a predetermined lag time or more. If T11 to T51 are not lost, the tile undetected signal is sent to the control system Sc as a first run end signal and processed.

Then, a stop signal is sent to the step motor Ms,
Tr stops by inertia running until the vertical edge on the -X side of the tiles T11 to T51 slightly exceeds X = 0 (that is, the position of the gun center line Cl) to the + X side. Further, in response to the air signal transmitted at the same time, each pinch valve 30 is closed, and the air cylinders 2.
, And then the carrier Cr starts moving in the + Y direction.

When this movement amount reaches 4 t mm, the carrier Cr stops at that position, and the step motor Ms starts reverse rotation.

This time, the five sensors 3 on the + X side, which were in the position of following up in the first run, were exposed and detected tiles T51 to T91, and the air cylinder 2 was actuated again and each gun 1 descended Then, the pinch valve 30 is opened, and joints are formed on the horizontal joint lines Jx5 to Jx8 as a second run.

In this way, the four horizontal crossing lines Jxi are sequentially lined up in the opposite direction, and when all n rows do not become a multiple of four, that is, even when less than the last four lines appear, in principle, Sensor pairs 3, 3 that will be exposed as seen from each gun Gn
As long as the tiles are both detected, mortar injection is performed in a way that the pinch valve 30 is opened, and after the end of the horizontal joint final run, the carrier Cr is returned to the original position,
The stepping motor Ms is rotated forward to move the truck Tr below the gate frame Fg1.

When the bogie Tr comes to a fixed position below the gate frame Fg1,
A limit switch (not shown) detects this, the stepping motor Ms stops, and the receiving arm Am of the direction change mechanism Dc moves to the pallet.
After lifting Pt and turning it 90 degrees horizontally, it is lowered onto the trolley Tr again. As a result, the arrangement of the tiles Tij of the wall panel Pw becomes the previous transposed matrix, that is, m rows and n columns, and the vertical joint lines Jyj
And the position of the horizontal line Jxi is switched.

Next, the stepping motor Ms rotates in the reverse direction, and the truck Tr retreats below the gate frame Fg2, and the tile T of the wall panel Pw
ij are detected by the sensors 3..., and jointing of the vertical joint lines Jyj is automatically performed in the same manner as in the case of the horizontal joint lines Jxi.

Thereafter, the pallet Pt is simply sent out to the next process together with the panel Pw from the rear end of the machine frame Fl.

According to the present embodiment, the circulation line Lc, the three-way 12 in the adapter 10, the passage 20c in the slide pipe 20, the plug passages 32d and 33d in the pinch valve 30, the rubber tube 36, and the passage 41c in the tip body 41. Supports mortar Mo supply path and supports traverse carrier Cr base plate Bp, air cylinder 2 piston rod 2a, adapter 10, slide pipe 20, pinch valve 30, tip body 41, stop cap 42, and triangular stay 7 and gun holder 6. A mortar gun 1 including a nozzle 43 as a body is prepared.
Is injected to perform the jointing, so that the jointing line can be aimed well and a superior filling effect can be achieved.

Further, since the pressure feed pump Pm is provided in the circulation line Lc, the original pressure of the nozzle 43 can be increased, and the gun structure can be simplified.

Moreover, since the portion of the mortar supply path excluding the circulation path Lc is housed in the nozzle support, the handling of the gun 1 is easy.

In addition, since the pinch valve 30 is provided in the mortar supply path, mortar Mo having high viscosity can be controlled easily.

In the present embodiment, when the mortar Mo is narrowed down and injected, the diameter d of the hole (FIG. 1) is changed to the joint lines Jxi, Jyj.
Although the straight nozzle 43 slightly larger than the width is used, the present invention is not limited to this. For example, an orifice formed on a stainless steel disk may be used.

(Effects of the Invention) As is clear from the above description, according to the present invention, it is possible to prevent the protrusion from the joint from the line perpendicular to the joint of the joint between the tiles of the tile panel from the joint and to prevent the joint from being jointed. The joint mortar is squeezed finely and injection-filled while leveling the joint surface, so that the mortar does not protrude from the joint and the aiming line can be aimed at and the toro can be packed. Are better.

Further, if the mortar is sprayed with a nozzle, it is easy to mechanize, so that a large amount of jointing of prefabricated materials, especially wall panels, can be performed at one time, which greatly contributes to mass production.
