Description
【発明の詳細な説明】 本発明はピストン式充填機の改良に関する。[Detailed description of the invention] The present invention relates to improvements in piston-type filling machines.

る。 In conventional piston-type filling machines that have suction holes and discharge holes at the bottom of the filling cylinder, which are commonly used, the air sucked in during the suction stroke floats to the top of the filling cylinder and is not discharged during the discharge stroke, resulting in residual air. This causes a significant decrease in the measurement accuracy of the filling liquid in the filling cylinder.

下させる欠陥がある。 To improve this, there is a known method that prevents air from remaining at the top of the piston when filling is completed, as seen in Utility Model Application No. 53-140643. During the suction stroke, the air flows back into the liquid supply tank, floats up in the liquid, and escapes into the atmosphere, which causes air to mix with the liquid filled in the liquid supply tank, which is not only unfavorable from a sanitary standpoint, but also has the defect of deteriorating quality.

要旨とするものである。 The present invention is an attempt to improve these deficiencies with an extremely simple configuration.The suction hole provided at the lower end side of the filling cylinder is connected to the liquid supply tank, and the discharge hole is connected to the plunger cylinder. In this piston-type filling machine, the filling piston is formed to descend to the suction hole and the discharge hole, and the filling piston is formed so as to descend to the suction hole and the discharge hole. The main feature is that a one-way opening/closing valve is provided between the liquid tanks, and the communication portion between the discharge hole and the plunger cylinder is formed as a siphon communication hole that is inclined upward toward the plunger cylinder.

ランジヤーシリンダー８に連結されている。 An embodiment of the present invention will be described with reference to the drawings.A suction hole 2 and a discharge hole 3 are provided opposite to each other on the lower end side of a filling cylinder 1 provided around a rotary filling machine, and the suction hole 2 is connected to one side. It communicates with a liquid supply tank 6 via a branch pipe 5 having a directional valve 4, and the discharge hole 3 is connected to a plunger cylinder 8 by a siphon through hole 7 inclined upwardly toward the plunger cylinder.

されている。 The filling piston 9 fitted into the filling cylinder 1 has its actuating roll 10 connected to a cushion cam 11,
11 to move up and down, and especially when descending, its lower end surface is formed so as not to descend to the suction hole 2 and discharge hole 3 and suck air into the filling cylinder 1.

に放出される。 Since the embodiment of the present invention is constructed as described above, when the filling piston 9 is moved upward by the cushion cams 11 and performs the suction stroke, the liquid in the liquid supply tank 6 passes through the one-way opening/closing valve 4 and passes through the branch pipe 5. When the liquid in the filling cylinder 1 is sucked into the filling cylinder 1 through the suction hole 2 and then moves downward during the discharge stroke, the liquid in the filling cylinder 1 passes from the discharge hole 3 to the siphon passage hole 7 and the plunger cylinder 8, and from the filling nozzle 15 to the container A. When this filling action is completed, the liquid flows out of the triangular section 7' on the side of the plunger cylinder located above the discharge hole 3 in the siphon communication hole 7, forming an air reservoir. The air in the filling liquid is retained in this triangular cross section, and in the next discharge process of the filling piston 9, this retained air is pushed out together with the liquid into the plunger cylinder 8 and discharged from the filling nozzle 15 into the atmosphere.

改善した優れた特徴を有するものである。 The present invention prevents air in the filling liquid from remaining in the filling cylinder by lowering the filling piston of the filling cylinder, which has a suction hole and a discharge hole on the lower end side, to the suction hole and the discharge hole during the discharge stroke. At the same time, a siphon conduction hole is formed in the discharge hole that slopes upward toward the plunger cylinder, and air in the liquid is stored in a triangular cross-sectional part of the siphon conduction hole on the plunger cylinder side located above the discharge hole. Since this residual air is pushed out into the plunger cylinder by the filling liquid during the discharge stroke and released into the atmosphere from the filling nozzle, there is no possibility that the air in the filling liquid will remain in the filling cylinder or flow back into the liquid supply tank. It has an excellent feature that it can reliably prevent such problems from occurring, and it has improved the conventional defects of a decrease in measuring accuracy of the filling liquid and problems in terms of hygiene and quality.
