内包した筒状の包装材料１が搬送される。Further, a heat-welding portion 3 composed of a pair of heaters 3a and 3b driven by an air cylinder which is an actuator is provided, and both ends of the packaging material 1 joined by the both heaters 3a and 3b are appropriately sandwiched and released. Both ends of the packaging material 1 are heated by both heaters 3a and 3b in a sandwiched state and heat-welded, and then both ends of the packaging material 1 heat-welded by a pressing roller 4 provided at a subsequent stage of the heat-welding portion 3. A cylinder containing the packaged object until the packaged article is placed on the next conveyor 5 which is pressed horizontally and forms a conveyance path together with the conveyor 2 and is installed at a predetermined distance from the end of the conveyor 2. Shaped packaging material 1 is conveyed.

ような構成になっている。In this case, when the packaged object is retained in the heat-welded portion 3, the air cylinder is forcibly driven to heat-welded portion 3.
Both heaters 3a, 3b are moved so as to release both ends of the packaging material 1, and the direct heating of both ends of the packaging material 1 is stopped, but the heaters 3a, 3b themselves are energized. Is continued without being cut off, the ambient temperature around the heaters 3a and 3b is high, and if the object to be packaged stays in such a high temperature environment for a predetermined time or longer, it will be affected by heat. Since the commercial value of the packaged item may be reduced, such a packaged item is discharged.

上区別できないという問題がある。However, when the article to be packaged stays in the heat-welding section 3 for a predetermined time or longer, the commercial value of the article to be packaged may be reduced as described above. It is necessary to distinguish between the object discharged due to such accumulation and the object discharged due to biting, but in the above-mentioned conventional device, the pusher 8 similarly discharges the object already packed. However, there is a problem in that it is impossible to distinguish visually whether the article to be packaged is excessively heated by staying for a predetermined period of time or longer or is something else.

When it is cut off or the air pressure is reduced, the driving force of the air cylinder is reduced and the heaters 3a and 3b return to the state of sandwiching both ends of the packaging material 1 again, and both ends of the packaging material 1 are returned. Will be directly heated again, and even if the residence time of the object to be packaged is within the above-mentioned predetermined time, the object to be packaged is affected by excessive heating due to malfunction of the air cylinder and both heaters 3a and 3b. Therefore, there is a possibility that such an object to be packaged may be conveyed as it is without being discharged.
