Problems solved by technology

[0004] However, the liquid filling and packaging device described in Patent Document 1 has the problem of poor opening and closing accuracy because the flow regulating valve is air-driven.
In addition, if the change of the liquid supply pressure from the filling liquid tank exceeds a certain range, the liquid level cannot be controlled, and there is a problem that the filling liquid is sprayed or the liquid is insufficient.
Especially when the filling liquid is sprayed up, it is necessary to sterilize the device itself again, and it takes a long time to restore the old state, which is a big problem

Embodiment Construction

[0015] As the liquid filling and packaging device of the present invention, the following liquid filling and packaging device may be used, which seals both ends of the packaging material in the longitudinal direction to form a tube, fills the tube-shaped packaging material with a filling liquid, and fills the tube with the filling liquid. The tubular packaging material is conveyed downward by a length equivalent to approximately one container, while being sealed and packaged in a direction perpendicular to the longitudinal direction of the tubular packaging material, wherein the liquid filling and packaging device includes: a filling pipe of the flow regulating valve; a pressure sensor provided on the upstream side of the above flow regulating valve and detecting the pressure of filling liquid supplied from the filling liquid tank; a float having a magnet floating in the filling liquid filled in the tubular packaging material; A magnetic sensor that detects changes in the stren...

Abstract

PROBLEM TO BE SOLVED: To provide a liquid filling and packaging apparatus capable of precisely controlling a liquid face level of a filling liquid in a tubular packaging material molded in a tubular shape and preventing the filling liquid from spouting up and becoming insufficient.SOLUTION: The liquid filling and packaging apparatus includes a filling tube 12 equipped with a flow-adjusting valve 14 driven by a servo motor 16, a pressure sensor 18 provided on the upstream side of the flow-adjusting valve 14 and for detecting the pressure of the filling liquid fed from a filling liquid tank, a float 20 floated on the filling liquid filling the tubular packaging material B and equipped with a magnet, a magnetic sensor 22 for detecting a change in strength of a magnetism accompanying vertical movements of the float 20 equipped with the magnet, and a controlling means 24 for controlling the servo motor 16 to adjust the amount of opening of the flow-adjusting valve 14 based on the results of detection of the pressure sensor 18 and the magnetic sensor 22.

Description

technical field [0001] The present invention relates to a liquid filling packaging device capable of controlling the liquid level of a filling liquid in a tubular packaging material shaped into a tube with considerable precision. Background technique [0002] Conventionally, as such a device, a liquid-filled packaging device has been proposed that includes a float that floats in the filling liquid filled in a tubular packaging material and has a magnet, and that changes the strength of the magnetic field as the magnet floats up and down. A magnetic sensor that converts and outputs an electrical signal, and an air-driven flow control valve that is controlled based on the output signal of the magnetic sensor (refer to Patent Document 1). [0003] [Patent Document 1] Japanese Patent Application Publication No. 1-82102 [0004] However, the liquid filling and packaging device described in Patent Document 1 has a problem of poor opening and closing accuracy because the flow regu...
