である。 DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high viscosity varnish dispensing device. BACKGROUND ART Conventionally, as a means for drip-impregnating electrical equipment coils, a tube squeezing method, a gear pump method, a cylinder method, or a combination of these with a pressurized tank have been adopted. However, although either method is suitable for dispensing low-viscosity varnish or dispensing a large amount of varnish, if the varnish has a high viscosity or the dispensing amount is small, the dispensing accuracy may deteriorate and It was not possible to process it. In addition, models that use a pressurized tank have an excellent ability to discharge high-viscosity varnish, but when replenishing varnish into the tank, it is necessary to temporarily stop the varnish impregnation process and eliminate the pressure caused by air, etc. There must be. As a result, there was a problem of reduced productivity. The present invention has been made in view of this point, and provides a high viscosity varnish discharging device that enables desired varnish to be continuously dropped and improves productivity. Embodiments of the present invention will be described below with reference to the drawings. The figure is an explanatory diagram showing a schematic configuration of an embodiment of the present invention. In the figure, 1 is a varnish tank filled with a high viscosity varnish 2 having a viscosity of 5 poise or more at 25°C. A varnish circulation loop 3 is provided above the varnish tank 1 with its inlet 3a and outlet 3b immersed in the crocodile 2. A gear pump 4 is attached to the varnish circulation loop 3. A flow control valve 5 is installed near the outlet portion 3b of the varnish circulation loop 3. A bypass tube 6 is connected to a portion of the varnish circulation loop 3 between the flow control valve 5 and the gear pump 4 in a branching manner. Bypass tube 6
After passing through the tube squeezing pump 7, it branches into two, and a discharge nozzle 8 is attached to the tip of each. The discharge nozzle 8 is positioned above the coil end of the object to be processed, for example, an electrical equipment coil 9. According to the high viscosity varnish dispensing device 10 configured in this way, first, the gear pump 4 is driven to dispense the varnish 1 between the varnish circulation loop 3 and the varnish tank 1.
circulate. At this time, a part of the varnish 2 passes through the bypass tube 6 and is squeezed by the tube squeezing pump 7, and then supplied to the discharge nozzle 8. The amount of varnish 2 flowing through the varnish circulation loop 3 is adjusted by a flow control valve 5, and the varnish 2 is supplied to the tube ironing pump 7 side in an appropriately pressurized state. Next, since the tube squeezing pump 7 is driven and repeatedly starts and stops, the high viscosity varnish 2 is discharged at a fixed rate and at a constant rate from the discharge nozzle 8 toward the electrical equipment coil 9 by adjusting the driving time. be able to. Further, since the varnish tank 1 is in an open state, replenishment of the varnish 2 and cleaning of the varnish circulation loop 3 and the like can be easily performed. In particular, when using a fast-curing epoxy varnish with a short pot life (stability), the varnish is applied at predetermined intervals depending on the amount used.
The varnish can be mixed, supplied to the varnish tank 1, and continuously dripped from the discharge nozzle 8. Furthermore, the varnish 2 can be easily replenished into the varnish tank 1 without interrupting the dripping operation. As a result, productivity can be significantly improved. Further, by using the tube ironing pump 7, the highly viscous varnish 1 can be easily continuously discharged. As explained above, according to the high viscosity varnish discharging apparatus according to the present invention, it is possible to continuously drip a desired varnish and improve productivity.
