Featured is a web sealing device for controlling the sealing pressure so as to carry out a sufficient sealing while monitoring the sealing pressure directly acting on the web. Also featured is a packaging container producing equipment using the aforementioned sealing device and a packaging container producing method using the same. When sealing a part of web W by engaging hooks 16a, 16b, which directly give a sealing pressure to the web W in order to seal a part of both web N by heating and melting both side surfaces of a double web while pressing the same, the strain amount of the hooks 16a, 16b is measured by a strain gauge 23. and the aforementioned sealing pressure is controlled by the controller 21 so that the waveform of the data, in which the values obtained by converting the aforementioned measured strain amount to pressure are continuously recorded in line with the elapse of time, becomes nearly identical to that of the master data, reflecting on the compressing time by the hooks 16a, 16b, compression timing, and the pressing force of the cylinder 18 for actuation of the hooks, and the adjustment of the drive amount of the drive device for the cross sealing of a pair of sealing jaws 7a, 7b.

There is provided a superhigh-speed filling and packaging apparatus having a high performance capable of manufacturing more than 8,000 packs per hour without leaving fluid at sealed parts of the containers. The filling and packaging apparatus fills a packaging material web formed in a tubular shape with fluid to manufacture package containers. The apparatus includes a lateral sealing apparatus for laterally sealing the tubular web filled with the fluid at intervals, each corresponding to one container, and a cutting apparatus, disposed under and remote from the lateral sealing apparatus, for cutting sealed parts of the containers while the containers are suspended to separate the containers.

The invention is to provide a method and a device, etc. for molding tubes, free from any fear of the web being broken, which do not generate any wrinkle on a web when molding a plate-like web to rectangular parallelpiped packaging containers via a tubular web. In a tube molding method of the invention for molding a plate-like web to a tubular web while transferring the former along the roller surface formed by a plurality of rollers 11 through 13 of the molding roller 4, a roller supporting plate 16 is turned by a tightening member 29 while being position-regulated by a roller 25 attached to the roller attaching arm 23 so that web is transferred on the basis of the hypothetical center axis line (Point X) of the tubular web, which is formed by the roller surface constituted by the rollers 11 through 13, wherein the web in the lengthwise direction can be accurately transferred so that the same web takes a predetermined orientation of the rollers 11 through 13. As a result, it is possible to produce a high molding accuracy, for which the creasing lines of web in the lengthwise direction are made coincident with ridges of square-post-like web in its lengthwise direction when molding the square-post-like web from the tubular web.

To provide a heat-sealing apparatus capable of: achieving a complete sealing property by causing a liquid or dirt having entered small irregularities in a tube inner face to flow out of a sealed zone together with a molten resin; and a heat seal with no crack caused by the molten resin having flowed into container and with an excellent compression strength. A heat-sealing apparatus for forming a packaging material 1 made of a laminate including a synthetic resin layer into a tubular-shape of a container, and transversely heat-sealing a tubular packaging material container filled with fluid by using a sealing jaw 3 having a high-frequency coil 2 with a ridge 11 on its flat pressing face and a jaw 5 opposing to it, wherein a first groove 16 is disposed on at least one pressing face of the high-frequency coil 2, capable of forming a synthetic resin bulge adjacent to the outer side of a zone to be sealed on a container's interior side.

There is provided a press capable of solving a new problem of breakage of springs and surely applying the pressure for a long period of time in the lateral sealing process in a high-speed filling and packaging apparatus for manufacturing package containers each having a rectangular shape in cross section and filled with a fluid content such as juice. In the press comprising seal bars and a pair of engaging members which are respectively provided at both ends of the seal bars for producing a sealing pressure when they engage with each other for permitting said seal bars to nip a packaging material web which is filled with a fluid content and formed in a tubular shape, the press employs fluid such as air as a means for advancing a piston rod to which the movable engaging member is secured and a pressure sensor is provided for detecting the change of pressure of fluid in an air supply passage.

An object of the present invention is to provide a sterilizing liquid remover and a method of removing the sterilizing liquid which can easily remove/dry the sterilizing liquid which remains at the step portion formed by the sealing tape and the web which forms the container's interior side in the packing material web having the sealing tape adhered to its side end portion. Driblets on the surface of the web are squeezed by squeeze rollers 30 disposed such that they can open and close while sandwiching the transfer route of the web W having the sealing tape adhered to its side end portion therebetween, the heated air is blasted at the step portion formed by the sealing tape and the web by the second air knife 20, then the heated air is blasted at the whole width of both faces of the web by the first air knives 10, and the sterilizing liquid is removed. The remaining blown driblets at the step portion can be also removed by the second air knife 20 which can blast the heated air widely and laterally at the step portion.

A cutting device is provided for securing the cutting of the lateral sealed parts of a tubular packaging material web in the filling and packing machine of a filling and packaging apparatus that manufactures package containers each have a rectangular cross section and are filled with a fluid such as juice, etc. The cutting device includes the tubular packaging material web which is filled with a fluid, a pair of seal bars for laterally sealing the packaging material web, a cutter for cutting the packing material web at sealed parts thereof by a length corresponding to one container, fluid (such as air) pressure serving as a means for giving a biasing force to the cutter in a direction to retreat the cutter, and a pressure sensor capable of detecting a change of the fluid pressure in the supply passage.
摘要:
The action pattern of the amount of web feeding by the lug folding flaps is made optimal in accordance with deviations of detection marks, such as specified printing patterns on the printing surface on web W, from the reference values when they are detected, and the pressing force applied onto web W by dancer roller 9 is stepwise or continuously adjusted according to the detection of the patterns. Therefore, in comparison with the conventional examples, it is possible to widen the corrective range for the amount of web feeding. Thus, the tolerance for printing errors on web W can be increased, and it is possible to operate the equipment without stopping. Furthermore, it is possible to produce packaging containers with printing patterns applied at appointed positions, and faulty products are eliminated.
