The liquid in the container is heated or cooled by spraying a heating medium or a cooling medium while transporting the liquid.

The degree of heating or cooling varies depending on the liquid in the filled container, etc., so the inside of the device is usually divided into several parts and the temperature detector, temperature controller, etc. installed in the heating and cooling zones. It is customary to control the supply amount of the heat medium. Then, the container is heated or cooled while passing through the inside of the apparatus and reaches a predetermined temperature.

(Problems to be solved by the invention) By the way, in a filling device for filling a multi-type container with liquid, the setup time for changing the type of liquid to be produced is becoming shorter. However, since the set temperature of the heating or cooling device for the container filled with liquid is determined by the product type, the temperature at which the temperature of the heating and cooling zones is adjusted until all the containers previously produced have exited the device. It was not possible to change the setting temperature of the controller. For this reason, when liquid types having different temperature conditions are to be produced next time, it takes time to raise or cool the temperature.

The present invention is intended to solve the above conventional problems.

(Means for Solving the Problems) Therefore, according to the present invention, a container filled with a liquid is sequentially supplied, and a heat medium for heating or cooling is brought into contact with the container during conveyance to heat or cool the liquid inside the container. After cooling, in the liquid heating or cooling device that sequentially discharges the container, a mechanism that gives a set temperature change signal to the heating or cooling zone in the device, the position of the last container in the device from this signal as a starting point. A means for solving the problem is provided which is provided with a detection mechanism for detecting and is capable of sequentially changing the set temperature of the heating or cooling zone while detecting the position of the rearmost container. It is what

(Operation) An iron piece is attached to the drive source of the container transfer device, the transfer state is detected by the proximity switch, and the signal is input to the controller. In addition, a push button switch for starting the temperature setting change and a changeover switch for the next product type setting are added and input to the controller. Then, when the end of the container that has been produced so far enters the heating or cooling device, the push button switch for starting the temperature setting change is pressed. After this signal is input, the control device starts counting the signal of the proximity switch that detects the movement of the transport device. And if each counter counts up,
Since the container has passed through the zone, the set value of the temperature controller can be changed to the set value of the liquid type to be produced next.
