A packaging and filling apparatus for keeping pressure of filled liquid food in a tube at positive pressure, facilitating preformation by a forming flap, and preventing an external ambient substance from entering the tube even if the liquid food pressure lowers to negative pressure by a fluctuation of the liquid food pressure is described. The apparatus has a pressure flange provided below a liquid level in a tubular packaging material and along an outer periphery of a filling pipe. The pressure flange prevents the liquid food in the tube from freely flowing up from the lower part to keep the pressure of the liquid food positive in the tube below the pressure flange thereby facilitating the preformation by the forming flap. The apparatus closes a gap occurring on a seam serving as a vertical sealed part or a portion where the gap might occur.

Packaging and filling machine

A packaging and filling machine that is capable of easily preforming with the forming flaps by keeping the pressure of the filled liquid food in the tube at positive pressure, capable of preventing the pressure of the liquid food from dropping to negative pressure, even if the pressure of the liquid food decreases due to the change in the liquid food pressure, and capable of preventing outside atmosphere materials from invading into the tube. A pressure flange fixed on a periphery of the filling pipe absorbs fluctuation of the pressure of the liquid food in the tube below the pressure flange, and prevents the liquid food pressure from dropping to negative pressure to keep the pressure of the liquid food in the tube below the pressure flange at a positive pressure.

A packaging and filling machine is capable of easily preforming with the forming flaps by keeping the pressure of the filled liquid food in the tube the positive pressure, capable of preventing the pressure of the liquid food from dropping to negative pressure, even if the pressure of the liquid food decreases due to the up-and-down of the liquid food pressure, and capable of preventing outside atmosphere materials from invading into the tube. A positive pressure keeping means absorbs fluctuation of the pressure of the liquid food in the tube below the pressure flange, and prevents the liquid food pressure from dropping in negative pressure to keep the pressure of the liquid food in the tube below the pressure flange a positive pressure.

An object is to enable a strip tape to be bonded to a packaging material at a proper position and enable longitudinal sealing to be performed well. A packaging-container manufacturing apparatus includes a bonding member, a first detection section which detects an edge of the packaging material, a second detection section which detects an edge of the strip tape (), position determination processing means for determining the position of the strip tape () in relation to the packaging material, and position correction processing means for correcting the position of the strip tape () in relation to the packaging material. Since the position of the strip tape () in relation to the packaging material is determined on the basis of outputs of the first and second detection sections and the position of the strip tape () in relation to the packaging material is corrected on the basis of results of the determination on the position, the strip tape () is placed on the packaging material at a proper position.

Packaging-container manufacturing apparatus and packaging-container manufacturing method

A packaging and filling apparatus fills a tube of a web of a packaging material with a fluid product, forms lateral seal bands, cuts each seal band of a series of pillow-like preformed bodies with a cutting device to form a packaging and filling container of the final form. The cutting device comprises a resistance measuring device for measuring a cutting resistance pressure that a packaging material cutting blade receives from the packaging material, and then outputting a measurement value obtained, and a blade monitoring device for monitoring the condition of the packaging material cutting blade based upon based upon a comparison of a difference between a maximum measured cutting resistance pressure and a constant measured cutting resistance pressure following the maximum measured cutting resistance pressure with a predetermined pressure difference reference value.

Packaging and filling apparatus and packaging material cutting device

A packaging filling apparatus, which can obtain the most suitable sealing quality by an automatic control without checking the condition of the sealing by the operator on a regular basis, is provided. A transversal sealing apparatus 48 of the packaging filling apparatus includes a high-frequency oscillator, controller, and an inductor, which generates a magnet field in packaging material by receiving the output from the high-frequency oscillator, and is provided with a sealing quality control means, which transmits a control signal to the controller, based on a statistical relation between a plurality of effect factors affecting the quality of a transversal sealingand the quality of transversal sealing.

Packaging filling apparatus and transversal sealing apparatus

When using web-shaped packaging material in which the rear end of a packaging material is spliced to the front end of a next web-shaped packaging material, in order to continuously operate the filling machine for paper container, notches are provided on a corner portion of the paper spliced portion around the metal layer. Even if a paper spliced portion is included in the web-shaped packaging material, in the filling machine seal insufficiency is not generated in the longitudinal seal of the paper spliced portions, and an interruption due to the broken part of continuous operation is prevented.

Filling method, filling machine and packaging material therefor

Flaw detection apparatus includes an electrode disposed in a region surrounded by a packaging material including a layer of an electrically-conductive material; a cutting member made of an electrically-conductive material and adapted to cut a predetermined portion of the packaging material; a variable detector, disposed between the electrode and the cutting member, for detecting an electrical variable; and flaw detection processor for reading the detected variable and for determining, on the basis of the detected variable, a flaw in the packaging material. In this case, the variable detector is disposed between the electrode and the cutting member.

A residual product removing apparatus which can prevent a liquid food (12) from flowing out even when a seal portion (S) is cut at its center. A pair of cutting rails (31, 32) are disposed in a cutting jaw (15a), and a cutter (21) is disposed in a clearance (33) formed between the cutting rails (31, 32) to be movable in advancing and retracting directions. A packaging material is cut at opposing portions (11a, 11b) when the cutter (21) is advanced. Dollies (31a, 32a) are disposed along the cutting rails (31, 32). A pair of heating bodies are disposed in a heat sealing jaw (15b) so as to squeeze and seal the opposing portions (11a, 11b) of the packaging material in cooperation with the dollies (31a, 32a). A groove (38) is formed between the heating bodies. The tip of the cutter (21) enters the groove (38) when the cutter (21) is advanced, and the tip of the cutter (21) presses the packaging material when the cutter (21) is located at its retracted position. Accordingly, no product remaining portion is produced between the opposing portions (11a, 11b) of the packaging material.
