摘要:
The present invention concerns a method and a device for sealing packages (1) during continuous movement. A row of packages (1) is driven by means of a motor (8) through a sealing station comprising an inductor (4). The inductor (4) is driven in a pulse form by means of an IH (induction heating) inductor (5). A PLC system (6) is used to control the IH generator (5). The PLC system (6) receives information regarding speed and position of the packages (1) by means of a motor drive (9) and an encoder (7), respectively.

In the pouch manufacturing method, a branched part (254) is formed by folding back at least one side part of a web-form body member (240) at a fold-back line running along the feeding direction of this body member. The body member (240) is guided by a guide so that the pass line length of a portion occupying an arbitrary position is substantially constant from the initiation of fold-back to the completion of fold-back; accordingly, a natural and favorable fold-back can be achieved without generating any slack or wrinkles in the web, so that pouches such as pouches having a branched part (254) can be manufactured with a favorable appearance and commercial properties.

Vorrichtung (10) und Verfahren mit einer Ultraschallschweißeinrichtung (14) zum Verschweißen von Werkstücken (13), wobei die Ultraschallschweißeinrichtung (14) einen Konverter, eine Sonotrode (16) und einen Amboss (17) umfasst, wobei die Sonotrode (16) zum Verschweißen in Richtung des Ambosses (17) schwingt und wobei die Sonotrode (16) um eine Achse (23) parallel zur Schwingungsrichtung (18) drehbar gelagert ist und sich beim Verschweißen dreht.
摘要:
A seal bar construction (100) is disclosed for thermally joining layers (29,31) of polymeric web (28) material. The construction (100) comprises an elongate seal bar (102) having a sealing surface and a heating arrangement. The heating arrangement provides a heating capacity that varies over the length of the seal bar (102) such that the polymeric web (28) material may be subjected to different degrees of heating. The variation of the heating capacity over the length of the seal bar (102) may be constant but may also be adjustable.

A method of manufacturing a bag (38) equipped with at least one spout, including the steps of holding a spout(s) (46, 47) inserted in a bag mouth(s) by spout gripping members (7) or inserting a spout(s) held by spout gripping members in a bag mouth(s), and sandwiching lightly the surface for sealing of the spout(s) with the bag mouth(s) interposed by heating plates (25) for an extremely brief time so that sealing does not occur, and then retreating the heating plates once, and then again sandwiching the surface for sealing of the spout(s) (46, 47) with the heating plates, thus thermally attaching the spout(s) to the bag mouth(s). If the axial rotational orientation of the spout (46, 47) drifts from the bag width direction, the spout is rotated in the spout gripping members (7) against friction force, so that the axial rotational orientation of the spout is corrected.

A method of continuously manufacturing a hermetic plastic zipper wherein the plastic zipper has a readily peelable plastic layer prolonging in a lengthwise direction of the plastic zipper, the readily peelable plastic layer is welded using ultrasonic wave so that the peeling intensity of the welded portion is within a certain range, the method is characterized in that while the engaging portions are brought into a engaged state, the portion of the plastic zipper where the readily peelable plastic layer exists is inserted between an ultrasonic horn and an anvil, and the readily peelable layer is welded by using ultrasonic wave under a condition wherein the distance L between the ultrasonic horn and the anvil is uniformly held at an distance of H≧ L≧ 0.85H wherein H stands for a maximum thickness of the plastic zipper under the engaged state.

A belt-like film (43) is moved along a plate (41) folded to be rectangular in section, so that the film (43) is formed into a continuous tube by a tubular frame of the plate (41). One end of a spring piece (46) is fixedly set to a base block (45). An anvil (47) is formed on the other end of said spring piece (46), so that clasped-hands like edges of the tubular film (43) may be melded by the cooperation of the aforementioned anvil (47) and a movable hammer (50) which applies ultrasonic vibratory impact on said anvil (47).
摘要:
A self-aligning zipper seal module adapted for quick change-out in a sealing carriage. The zipper seal module allows for a quick modification of a sealing carriage in order to accommodate different package dimensions. The module is stored and is installed in a closed and aligned position by an alignining handle (576). The module is easily installed or removed with a single tool and is designed to reduce the potential for operator injury by isolation from heat source and by virtue of the aligning handle. The various sealing facings of the module are oriented to equalize pressure on the facings during sealing and increase stripping efficiency. The zipper sealing facings (440, 442) incorporate a novel insert design (798), thereby eliminating the need for stocking different sized facings to accommodate various bag widths. A return module of similar design is used to quickly return the sealing carriage to a standard configuration.
摘要:
An apparatus and method capable of separating plastic films from garbage for collection is taking advantage of ductility of plastics, separation and extensibility properties of plastic films in water, and adhesion property of water to plastic films in order to provide a novel and unique garbage disposal implementation of rapidly, effectively, conveniently, and precisely separating medium-sized, light materials and plastic films from small garbage for collection and perform an initial cleaning of garbage by means of water while classifying garbage for facilitating a subsequent garbage disposal.
