Abstract

PROBLEM TO BE SOLVED: To provide a method for welding a port plug capable of stably welding the plug from the time of starting its operation to the time of finishing in the method for welding the plug comprising a step of welding the plug to a sleeve (a blank punched in a developed plane of a container is back adhered and folded) of a paper container for a liquid by an ultrasonic oscillation horn in a filling and packaging machine for filling a liquid content. SOLUTION: The method for welding the port plug comprises the steps of passing a circulating water 111 into an anvil 110, inserting the sleeve 210 of the paper container for the liquid into the anvil, and welding the plug 220 to the discharge port position of the sleeve by the ultrasonic oscillation horn 120.

Description of the Related Art Conventionally, when a large amount of liquid contents are filled in a liquid paper container, for example, the liquid contents, the sleeve of the liquid paper container, the spout, etc. are loaded into a liquid filling and packaging machine and the sleeve is poured. A liquid paper container, in which a stopper was welded at the outlet position by ultrasonic welding and the bottom seal, content filling, and top sealing, were filled with the content, was mass-produced at high speed. In addition, the method of attaching the stopper is to weld the upper surface of the flange of the plastic stopper to the plastic layer on the inner surface of the liquid paper container (internal attachment), and to attach the lower surface of the flange of the plastic stopper to the liquid paper. It was said to be welded to the plastic layer on the outer surface of the container (external attachment).

It is generally known that when the ultrasonic oscillator with a high frequency of 30 kHz is used at a speed of 3,000 pieces per hour, it is difficult to weld the mouth plug in the morning and excessively welded in the evening. It was being done. This is because when the temperature is low in the morning, the spout is cold and the resin does not melt sufficiently. In the evening, continuous use causes the horn and anvil (anvil,
This is because the pedestal) accumulates heat and becomes hot. Especially in cold regions, the entire machine is extremely cold at the start of operation in the morning, so that the spout is not welded and the spigot itself is preheated and placed in advance.

アンビルには、全く温度制御機構がついていなかった。The inventors measured the change in the welding energy with respect to the change in the surface temperature of the anvil. The welding energy was 114 when the surface temperature of the anvil was -1 ° C.
J, the welding energy was 118 J when the surface temperature of the anvil was 17 ° C., and the welding energy was 127 J when the surface temperature of the anvil was 59 ° C. When these measured values were viewed in a graph, it was found that the relationship between the surface temperature of the anvil and the welding energy was almost linear, as shown in FIG. From this, it was judged that controlling the surface temperature of the anvil to be constant is an effective means for stabilizing the welded state of the spout. However, the conventional anvil has no temperature control mechanism.

用ホーンにより外付けで溶着してもよい。BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a spout welding method according to an embodiment of the present invention allows circulating water (111) having a predetermined temperature to pass through an anvil (110) and a spout Insert the sleeve (210) of the liquid paper container in which the plastic stopper (220) is projected and set in the position, and attach the upper surface of the flange (221) of the stopper and the plastic layer on the inner surface of the sleeve to the tip portion. Is a ring-shaped ultrasonic wave horn (120) which is pressed from the outer surface of the sleeve and internally welded. Depending on the intended use, the spout may be set on the outer surface of the outer peripheral edge of the spout hole of the sleeve, and the bottom surface of the flange (221) of the spout may be set on the outer peripheral edge of the spout hole of the sleeve. It may be welded externally by a plastic layer on the outer surface and an ultrasonic horn.

A 0 ml liquid paper container was continuously filled, and the change with time in the surface temperature of the anvil due to the welding of the plug at that time was measured. The initial temperature of the anvil is -10 ° C, the temperature is 16 ° C, and an ultrasonic oscillator of 30 kHz is used.
Horn pressure is 0.20 MPa, oscillation time is 0.20
It was sec. In addition, for comparison, measurement was also performed when circulating water was not passed. The measurement result is shown in the graph of FIG.
