成形装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a heat-sealing packaging material in the form of a tray, such as a pre-formed container, in which articles such as toothbrushes and other products are placed, and the lid or cover sheet is heated. The present invention relates to a packaging container forming apparatus for forming a package formed by sealing and wrapping.

することが知られている。Generally, in order to bond a container-shaped packaging member and a lid-shaped packaging member made of a thermoplastic synthetic resin made of a plastic material to each other to form a package, it is often necessary to use a heat seal, an ultrasonic seal, a high frequency seal, or the like to weld the package. In the high frequency welder welding step in induction heating or dielectric heating with the high frequency seal, the object to be bonded is sandwiched between the upper mold and the lower mold, and a high frequency current is applied while applying a constant pressure to perform heat bonding. It has been known.

点があって問題であった。In a conventional package, a heating process for high-frequency welding and fusing in which a container-like member and a lid-like member are combined with each other. In a production mode where the heating process is continuous, heat is likely to accumulate in the upper mold and the lower mold. In particular, the upper mold having a large contact area with the package is remarkable, and often causes a problem that the temperature is increased and an object to be bonded (hereinafter referred to as a work) sticks to the upper mold.
Even when the upper and lower dies open when the mold is released, if the temperature approaches the welding temperature of the work, the work will adhere and the upper mold for thermoforming will lift and move or float, so use equipment with multiple lower dies. In the case of the type that is moved to the next step, there is a high possibility that the lower mold hits the package and crushes the package, and if a long cooling time is employed to eliminate this bad phenomenon, the capacity of the equipment will decrease. However, there is a disadvantage that the cycle time per product unit is prolonged and the productivity is reduced.

空ポンプに連通する状態下にセットされる。In the packaging container forming apparatus of the present invention, a tray-shaped heat-sealing packaging material in which a plurality of container-shaped recesses are formed in advance is sequentially placed in a lower mold on a moving table that moves intermittently. After the lower mold is moved to a predetermined position and the articles, for example, toothbrushes are put into each of the container-shaped recesses, the tray is moved to the predetermined position. The heat-sealing packaging material of the lid member is placed on the heat-sealing packaging material and polymerized, and then moved to a position immediately below the upper mold serving as a welding station by moving the table, and then the upper mold is lowered. The peripheral edge of each article is simultaneously sandwiched between an upper mold and a lower mold, and high-frequency welding is performed while applying a constant pressure to form a package, and a plurality of packages are formed on a sheet in an easily separated state. At this time, only the lower mold that has been transported immediately below the upper mold and stopped is set in a state in which the suction passage opened in the pocket portion communicates with the vacuum pump by the rotary joint / switching valve.
