供給することができない。 Although this system is suitable for continuously supplying molten resin, it has not been possible to intermittently supply a fixed amount of molten resin even if the system is operated continuously. That is, when the extruder is stopped,
There is residual pressure in the flow path and instantaneous stop is not possible. Therefore, since the molten resin is viscous, sagging occurs.
Unless this sagging is removed, molten resin cannot be newly supplied.

溶融状態を保持するようになつている。 FIG. 1 shows one of the molten resin quantitative supply devices according to the present invention, in which a supply device is provided between an accumulator 1 that accumulates molten resin P and a supply port 2 from which the molten resin P is discharged. A metering pump 4 is connected in the middle of the passage 3. This metering pump 4 has a specified amount of fluid to be discharged per rotation, and a constant rotation of the metering pump 4 accurately provides a constant amount of fluid to be discharged. The metering pump 4 is driven by a motor 5, and a forward/reverse rotation switching mechanism 6 and a speed reducer 7 are interposed between the two. In the illustrated drive transmission structure, the forward/reverse switching mechanism 6 may be, for example, a mechanical clutch mechanism, but it may also be electrically switched using a relay circuit. Note that a heater 8 is provided in the accumulator 1 and the supply path 3 to maintain the molten state of the molten resin P.

力度合を調整することができる。 The replenishment part B is provided with a resin material in the accumulator 1.
The extruder 9 is connected to an extruder 9 that heats and melts P'', and the extruder 9 responds to the accumulated amount of molten resin P in the accumulator 1. It consists of an internal plunger 10, a rod 11, a cylinder 12 that pressurizes the molten resin through the plunger 10, and limit switches 13 and 14 installed at the upper and lower ends of the vertical motion range of the rod 11, respectively. is linked to an electromagnetic clutch 16 provided between a motor 15 that drives the extruder 9 and the extruder 9, and when the rod 11 operates the upper limit switch 13, the molten resin P in the accumulator 1 is accumulated. When the amount reaches the limit, the electromagnetic clutch 16 is disconnected to stop the operation of the extruder 9, and when the rod 11 operates the lower limit switch 14, that is, the amount of accumulated molten resin P in the accumulator 1 is reduced. When the electromagnetic clutch 16 is connected, the extruder 9 is operated. Therefore, if the resin material P'' is thrown into the hopper 9a of the extruder 9 at the appropriate time, it will be heated and melted by the screw 9b and the heater 8. The molten resin is replenished as needed, making it possible for the supply section A to continue supplying the molten resin P. In addition, in order to protect the accumulator 1,
It is preferable that a pressure sensor 17 is attached to the accumulator 1 so that the electromagnetic clutch 16 is disconnected at a constant pressure. Furthermore, if a pressure regulating valve 18 is attached to the cylinder 12 that pressurizes the molten resin P via the plunger 10, it can protect the accumulator 1, and the molten resin P of the plunger 10 can be protected.
The pressurized state, that is, the degree of pressure at which the plunger 10 moves up and down can be adjusted.

がなくなる。 In FIG. 2, a flow path 19 for molten resin P is provided on the side wall of the connection part of the accumulator 1 with the extruder 9, so that the molten resin P sent from the extruder 9 flows below the plunger 10, and The molten resin P remaining in the supply channel 1 enters the supply channel 3. By providing this flow path 19, a part of the molten resin P will not remain in the accumulator 1 forever and will not deteriorate in quality.

る。 When using this device, first use the metering pump 4.
is rotated in the forward direction to fill the molten resin P from the accumulator 1 to the supply port 2. Then, when the metering pump 4 is rotated forward a set number of times, a predetermined amount of molten resin P is discharged and supplied from the supply port 2. When the forward rotation of the metering pump 4 is stopped, the discharge and supply of the molten resin P from the supply port 2 is also stopped.
Since sagging occurs, the forward/reverse switching mechanism 6 is operated to rotate the metering pump 4 in the reverse direction. By rotating the metering pump 4 in the opposite direction, the sag is sucked into the supply port 2. In other words, the amount of molten resin P discharged and supplied from the supply port 2 becomes an accurately set amount. In addition, the suction of this drip prevents the molten resin P from solidifying due to the cooling of the air at the supply port 2, and also prevents the molten resin P from deteriorating due to the temperature difference between the heating by the heater 8 and the cooling by the air. Become. In this way, if the metering pump 4 is rotated forward again, the set amount of molten resin PK will be reached again.
Discharge supply is obtained. Therefore, an accurate and constant amount of molten resin P can be discharged and supplied intermittently.

This is an example in which the coating layer P' is formed by coating the coating material T, and the objects to be coated T are lined up at regular intervals on a production line that flows from left to right in the drawing. Figure 3 shows a state in which the object T to be coated is located directly below the supply port 2, and a state in which the molten resin P discharged from the supply port 2 is applied to the rotating object T is shown. . FIG. 4 shows the state from the time when the coating layer P' is formed in the state shown in FIG. The state where the drip is being inhaled is shown. In this way, an accurate fixed amount of molten resin P is supplied to the object T to be coated, and there is no possibility that the product finish of the object T to be coated will be deteriorated or the production line will be contaminated.
