Abstract

PURPOSE:To make it possible to perform a film welding in an excellent condition by always setting a proper welding temperature by providing a temperature sensor and directly detecting the temperature around a sealing part including a heater line. CONSTITUTION:A non-contact temperature gauge 8 utilizing infrared ray, etc., is installed on the front surface of a sealing part including the heater line 3 of a sealing device, and the temperature of the heater line 3 or the temperature around the sealing part as the welding temperature for the film 1 is directly measured and detected each occasion. The exactly detected welding temperature measured value is transmitted to a CPU 10 via a temperature input part 9, the value is compared and calculated with the initial condition inputted preliminarily in a setting part 11, the obtained output signal is inputted in a heater control part 12 and the energizing time to the heater line 3 which becomes a proper welding temperature is controlled. Because the welding temperature is exactly detected each occasion even when the sealing part is gradually stored in the sealing work to be performed in this way, the proper energizing time is controlled based on the detection signal.

Is placed and pressed from above by the pressing lid 2 via the crimping plate 6, and then the heater wire 3 is energized for a predetermined time for welding and sealing. At this time, as shown in the figure, a thermometer 7 such as a heat-sensitive element is attached near the heater wire 3 so that good welding can be performed, and the energization time to the heater wire 3 is controlled based on the measured value to obtain an appropriate value. It was designed to obtain the welding temperature.

放熱効果が得られるものとならなかった。When the impulse sealing operation is repeated, the heat of the heater wire is accumulated without being dissipated, and there is a possibility that the film will be melted by being overheated during the initially set energization time. . Therefore, as shown in FIG. 4, a heat radiator 5 is installed near the heater wire 3 to prevent heat accumulation. However, providing an excessively large heat radiator will increase the size and weight of the apparatus, and this is the only reason. Then, the heat dissipation effect was not sufficient.

が生ずるものとなる。In order to prevent fusing of the film due to overheating of the seal portion due to such heat storage and to obtain good sealing property, it is necessary to always grasp the welding temperature by the gradually changing heater wire accurately. In this method, the temperature of the heater wire itself is not detected, but the temperature in the vicinity thereof is detected, so an error occurs due to a difference in heat conduction from the actual temperature.

The film bag 1 containing the filling material in the filling step A is delivered to the vacuum packaging step B, and the inside of the plurality of vacuum chambers B is filled. After being evacuated in each chamber, each chamber is sealed in the same chamber B and discharged to the next step. In the vacuum packaging apparatus, the sealing in each vacuum chamber 13 is performed. Since the thermometer 7 is installed for each device, there are problems that the facility cost is high and the security management is troublesome.

なる等の優れた効果がある。When the method of the present invention is applied to a vacuum packaging apparatus as shown in FIG. 3, a non-contact type or contact type temperature sensor is provided near the position where the bag 1 is received from the filling step A,
When the vacuum chamber 13 is opened, the temperature of the heater wire (or its vicinity) of the seal portion provided inside is measured, the heat storage state is grasped from the measured value, and the energization time can be controlled. Since it is not necessary to provide a thermometer for each vacuum chamber as in the conventional case, and one temperature sensor can be provided for one vacuum packaging device, equipment cost is reduced and installation is very difficult. It has an excellent effect such as being easy to use.
