BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for applying mortar to a panel surface to which tiles are attached by using a nozzle.

[0002]

2. Description of the Related Art Recently, a dry wall construction method using a tile panel which does not require a skilled technique for sticking tiles and requires no curing time for drying and solidifying mortar or the like as an adhesive in the field. Is being developed. When such a tile panel is manufactured, usually, as shown in FIG. 4, a panel 1 on which a tile such as a lightweight concrete panel, an extruded cement board, a calcium silicate board, or the like is attached is prepared, and the surface of the panel 1 is provided. Mortar 2 as a cement-based adhesive is applied by flowing from a hopper 3. Then, the tiles arranged at predetermined intervals are adsorbed by a tile adsorber provided with a suction cup on the lower surface and pressed against the surface of the panel 1 on which the mortar 2 is applied. Finally, a predetermined drying / curing step is performed. After that, it is a tile panel.

[0003]

As described above, in the conventional method of manufacturing a tile panel, since mortar is poured into the surface of the panel 1 and applied, for example, an opening or a notch for forming a window in the panel 1 is used. Is provided,
It was not possible to cope with this, and the mortar 2 was separately applied manually by a skilled worker. That is, it is inefficient and the burden on the operator is heavy.

Further, recently, the size of the tile panel itself has been increasing, and for example, the vertical and horizontal dimensions are 270.
0 × 5400 mm and the like. In the case of such a large tile panel, there is a problem that a thickness error, a curve, a warp, and the like are easily generated in the surface shape of the panel 1 itself. When the mortar 2 is applied to the panel 1 in which the shape such as the warpage is deteriorated, there is a drawback that it is not possible to apply the mortar 2 to a uniform thickness by the above-mentioned conventional casting method.

Further, when manufacturing such a large-sized tile panel, the hopper 3, the frame for arranging the tiles, the tile suction device, and the like must be adjusted to the entire size of the panel 1. There was a tendency to increase in size.
Also, the size of such a device itself was naturally limited.

[0006]

SUMMARY OF THE INVENTION The present invention has been developed in view of the above-mentioned problems and is improved and removed. The present invention can easily cope with an opening or a notch of a panel, and can apply a mortar uniformly, thereby reducing the entire apparatus. It is an object of the present invention to provide a mortar coating device that can be reduced in size. Therefore, a first means adopted by the present invention to solve the above problems is a nozzle for discharging mortar coming from a tank under pressure, and a mortar for controlling discharging and stopping of mortar from the nozzle. A mortar coating apparatus, comprising: a pouring control unit; and a unit configured to at least horizontally move the nozzle above an object to be coated with mortar.

A second means adopted by the present invention is a nozzle for discharging mortar pumped from a tank, a mortar discharge control means for controlling discharge and stop of mortar from the nozzle, and a mortar. Means for horizontally moving the nozzle at least above the object to be coated, means for detecting the distance between the nozzle and the mortar object, and raising and lowering the nozzle by an output signal of the distance detecting means, And a means for maintaining a constant distance from the mortar substrate.

[0008]

In the mortar coating apparatus of the present invention, the mortar is sequentially poured out from the nozzle to the mortar coating object such as a panel by coating the mortar on the panel by horizontally reciprocating the nozzle. Therefore, the mortar can be applied to the entire surface of the object to be coated without being affected by the size of the mortar by moving the nozzle horizontally and simultaneously intermittently conveying the object to be coated such as a panel. is there. Further, a distance detecting means such as a sensor using ultrasonic waves is provided on the side surface of the nozzle, and measures the distance between the tip of the nozzle and the mortar object. By moving the nozzle up and down according to the measurement signal, the mortar is always applied to the surface of the mortar object such as a panel at a constant distance. Therefore, even if the panel is deformed such as warpage, it is possible to make the applied thickness of the mortar uniform.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described below with reference to the embodiments shown in the drawings. The same reference numerals as those in the conventional case denote the same members. 1 and 2 relate to a first embodiment of the present invention, and FIG. 1 is an overall perspective view of a mortar coating apparatus showing a state in which a mortar 2 is applied to a surface of a panel 1 as a mortar object. FIGS. 2A and 2B are front views of the same apparatus as viewed from the transport direction side of the panel 1. FIG. As shown in the figure, an opening 4 for forming a window is formed in the panel 1 of this embodiment.

In this embodiment, the mortar 2 is connected to a tank for storing the mortar 2 via a pump or the like (both not shown) so that the mortar 2 can move horizontally and vertically above the panel 1. Nozzle 5. The spout 5a of the nozzle 5 is formed in a circular or rectangular shape, and a solenoid valve 6 is incorporated in the middle of the tip side of the nozzle 5. On the opposite side of the electromagnetic valve 6, a distance detecting means 8 such as an ultrasonic sensor is attached via an arm 7.

Next, the operation of the mortar coating apparatus thus configured will be described. First, the panel 1 is carried in by a roller conveyor (not shown) or the like below a region where the nozzle 5 moves horizontally, and the panel 1 is once positioned at this position. Then, the nozzle 5 is horizontally moved in a direction orthogonal to the panel transport direction. When the nozzle 5 reaches the position of the side end surface of the panel 1, the solenoid valve 6 is opened, and the mortar 2 pressurized by a pump or the like is poured from the outlet 5 a of the nozzle 5 and applied to the surface of the panel 1. When the nozzle 5 reaches the position of the side end face on the opposite side of the panel 1 in this way, the solenoid valve 6 is now closed to stop the mortar pouring.
At the time of horizontal movement of the nozzle 5, the distance detecting means 8 using an ultrasonic sensor or the like measures the distance between the nozzle 5 and the surface of the panel 1. When the distance changes, the nozzle 5 is moved up and down. The distance is kept constant. Thereby, the thickness of mortar 2 applied to the surface of panel 1 can be kept constant. Further, the supply of the mortar 2 is performed by turning on the pump O
It is also possible to control the discharge amount of the mortar 2 by controlling N and OFF.

After that, the panel 1 is conveyed by a roller conveyor, for example, by the width of the spout 5a of the nozzle 5. At this position, the nozzle 5 is moved backward in the horizontal direction, and when the nozzle 5 reaches one side end face of the panel 1, the solenoid valve 6 is opened to discharge the mortar 2 and reach the other side end face. Then, the solenoid valve 6 is closed to stop the mortar 2 from being poured. Thereafter, the above operation is repeated, and the mortar 2 may be sequentially applied to the surface of the panel 1.

When the nozzle 5 reaches the window opening 4 formed in the panel 1, the electromagnetic valve 6 is controlled to open and close at the position of the opening 4, so that the mortar 2 is discharged and stopped. You can control it. By pouring and applying the mortar 2 with the nozzle 5, the mortar 2 can be applied regardless of the size of the panel 1. Further, since only the horizontal drive mechanism and the elevating mechanism for the nozzle 5 are provided, the entire apparatus can be easily formed.

FIG. 3 is a perspective view showing an entire mortar coating apparatus according to a second embodiment of the present invention. In the second embodiment, four nozzles 5 are connected in series to apply the mortar 2 to the surface of the panel 1. The application procedure of the mortar 2 and the operation and effect thereof are the same as those in the first embodiment, and thus the description thereof will be omitted.

Incidentally, the present invention is not limited to the above-described embodiment, but can be appropriately changed. For example, the horizontal movement of the nozzle 5 may be such that the panel 1 is fixed, the upper part of the panel 1 is moved in a zigzag manner, and the mortar 2 is applied to the entire surface of the panel 1. The nozzles 5 may reciprocate zigzag in the same direction as the direction in which the panel 1 is conveyed, and the number of nozzles 5 may be set arbitrarily. Furthermore, in the case of applying the mortar 2 by the nozzle 5, the counterpart member to which the mortar 2 is applied is the back surface of the tiles arranged on the tile alignment frame or the back surface of the tiles adsorbed by the tile suction machine. Is also good.
