The wax supply unit 4 includes a wax storage tank 11 (hereinafter, abbreviated as tank 11) for storing the powdery wax 9. The lower end of the tank 11 is connected to the ejector 7 via the wax supply pipe 12. A net-like catch net (net-like member) 13 is provided at the bottom of the tank 11. The wax 9 in the tank 11 is stored in the tank 11 while being held by the catch net 13. The catch net 13 can prevent the wax 9 stored in the tank 11 from falling. Further, even if the wax 9 is aggregated in the tank 11, it can be crushed by the catch net 13 and the wax 9 can be dispersed more uniformly.

A cap 14 is detachably attached to the upper end of the tank 11. The wax 9 is housed in the tank 11 from above with the cap 14 removed. A filter 15 is attached to the upper part of the cap 14. When the cap 14 is attached to the tank 11, the inside of the tank 11 communicates with the outside air through the filter 15, and the inside of the tank 11 is supplied with clean air through the filter 15. As the filtered air enters from the upper part of the tank 11 in this way, the wax suction in the ejector 7 becomes smooth.

The blow gun 5 is a supply air adjusting means that functions as an on / off valve for turning on / off the supply of compressed air. The blow gun 5 is connected to a compressed air supply source (not shown) provided in the facility, such as a compressor, via an air tube 21. A port 22 to which the air tube 21 is connected is provided at the lower end of the blow gun 5. Compressed air is supplied into the blow gun 5 from the air tube 21 via the port 22. The blow gun 5 is provided with a lever 23 that controls the supply of compressed air. When the worker operates the lever 23, a valve (not shown) provided in the blow gun 5 is opened, and compressed air supplied from the compressor or the like is ejected from the air injection port 24. The air injected from the air injection port 24 is supplied to the ejector 7 through the air supply pipe 25.

The nozzle 6 is a blower nozzle, and here, a nozzle having a fan-shaped spray shape and a flat tip is used. The nozzle 6 is connected to the ejector 7 via a wax delivery pipe 31. A T-cross clamper 32 is attached to the ejector side of the wax delivery pipe 31. A T-bar (handle) 33 used as a handle for workers is attached to the T-cross clamper 32. The spraying device 1 is used in such a manner that an operator holds the T-bar 33 with one hand and operates the blow gun 5 with the other hand. The T-bar 33 can be attached to either the left or right side of the T-cross clamper 32 according to the dominant hand of the worker. The T-cross clamper 32 and the T-bar 33 may not be provided.

The ejector 7 is arranged below the tank 11, and the wax 9 in the tank 11 is sucked out by compressed air and supplied to the nozzle 6 in the subsequent stage. The ejector 7 is provided with a compressed air supply port 41, a wax suction port 42, and a discharge port 43. The compressed air supply port 41 is connected to the blow gun 5 via an air supply pipe 25. The wax suction port 42 is connected to the lower end of the tank 11 via the wax supply pipe 12. The discharge port 43 is a diffuser and is connected to the nozzle 6 via a wax delivery pipe 31. In the ejector 7, compressed air is supplied from the blow gun 5 to the compressed air supply port 41. The flow velocity of this compressed air is increased by the nozzle portion 44 provided inside, and the wax suction port 42 side is in a vacuum state. As a result, the wax 9 in the tank 11 is sucked out, and the wax 9 is delivered from the discharge port 43 to the wax delivery pipe 31 together with the compressed air.

Further, in the spraying device 1 according to the present invention, a bypass pipe 51 is provided between the air supply pipe 25 and the wax supply pipe 12. The bypass pipe 51 is provided with a needle valve 52. The opening degree of the needle valve 52 can be appropriately adjusted by the handle 53. As shown in FIG. 2, the bypass pipe 51 opens between the tank 11 and the ejector 7, and the air supply pipe 25 and the wax supply pipe 12 communicate with each other by operating the handle 53. When the needle valve 52 opens and the air supply pipe 25 and the wax supply pipe 12 communicate with each other, air flows from the pipe pass pipe 51 into the wax supply pipe 12. As a result, the wax 9 in the wax supply pipe 12 and the tank 11 is dispersed, and the clogging of the wax 9 is cleared.

Such a spraying device 1 is used in the final stage of the coating process, and is used by being inserted into the drum 8 of the pan coating device 2 as shown in FIG. At that time, the worker holds the T-bar 33 and the blow gun 5, and inserts the nozzle 6 into the rotating drum through the front opening 8a of the drum 8. Then, the nozzle 6 is arranged above the tablet 3 and the lever 23 of the blow gun 5 is operated. When the lever 23 is operated, compressed air is supplied from the blow gun 5 to the ejector 7, and the wax 9 is introduced from the tank 11 into the ejector 7. The wax 9 sucked into the ejector 7 reaches the nozzle 6 through the wax delivery pipe 31 and is sprayed on the tablet 3. The worker operates the blow gun 5 while appropriately changing the position of the spraying device 1 to evenly spray the wax 9 on the tablets 3 in the drum 8. As a result, the wax 9 is applied to the surface of the tablet 3 to produce a glossy tablet or the like.

On the other hand, when the wax spraying operation is performed, the wax 9 may aggregate in the wax supply pipe 12 and the amount of the wax 9 sprayed may decrease. In that case, the worker operates the handle 53 of the needle valve 52 to communicate the air supply pipe 25 and the wax supply pipe 12 via the bypass pipe 51. As a result, air flows from the pipe pass pipe 51 into both the tank 11 and the wax suction port 42, compressed air is blown into the wax supply pipe 12 and the wax 9 in the tank 11, and the wax 9 in the aggregated state is dispersed. To. Therefore, even when the spraying amount is reduced due to the aggregation of the wax, the clogging of the wax 9 can be cleared by opening the needle valve 52. As a result, the wax 9 is constantly supplied to the ejector 7, the amount of wax sprayed returns to the original state, and stable wax spraying becomes possible. Further, even a wax having a tendency to be clogged can be sprayed in a desired amount, and the wax quality can be improved.

As described above, in the spraying device 1 of the present invention, the wax 9 is sprayed from the nozzle 6 to the tablet 3 by inserting the nozzle 6 into the drum 8 from outside the device and operating the blow gun 5. At that time, the worker carries the spraying device 1 to each coating device, and waxes the tablets and the like there. Therefore, it is not necessary to provide a spraying device for each coating device, and one spraying device can perform wax treatment of a plurality of coating devices. Further, not only the coating device of the same building or room but also the factories having different sites can share one spraying device, and the device cost can be reduced. Further, since the wax is sprayed with the window opened from the front opening of the drum, it is easy to check the spraying status and spray the target portion, the workability is good, and the wax quality can be improved. In addition, in the spraying device, since the work is performed by inserting the nozzle from outside the device, it is not necessary to put a hand inside the device, and the safety of the worker is ensured.

It goes without saying that the present invention is not limited to the above-described embodiment and can be variously modified without departing from the gist thereof.
For example, in the above-described embodiment, the blow gun 5 is used as the supply air adjusting means when supplying the compressed air to the ejector 7, but instead of the blow gun 5, an on-off valve using a cock or the like is used. You may. However, as for the adjustment means, a hand gun that can open and close the valve with a finger to adjust the flow rate of compressed air can finely adjust the spray amount while visually checking the spray status, so it is easier to operate. It is preferable in terms of surface. Further, in the above-mentioned spraying device 1, compressed air in a facility or the like is supplied to the blow gun 5 by an air tube 21, but a cylinder in which compressed gas is stored in a pressure-resistant container, such as a small carbon dioxide cylinder, is used. It may be used as an air supply source.

The present invention can be applied not only to the wax treatment of tablets but also to the wax treatment of foods such as confectionery and gum. Further, the spraying device 1 according to the present invention can be used not only for wax treatment at the final stage of coating treatment but also for simple coating treatment and the like. Further, it can be widely applied to coating devices other than the pan coating device as shown in FIG.
