Definitions

  • the present invention relates to a bag making and packaging machine.
  • a bag making and packaging machine using an ultrasonic sealing method has been used as a bag making and packaging machine that forms a bag and fills the bag with food to be packaged and hermetically wraps the bag.
  • This bag making and packaging machine forms a wrapping material, which is a sheet-like film, into a tubular shape (tube shape) with a former and a tube, and seals the overlapping vertical edges of the tubular wrapping material. Then, after filling the inside of the tube-shaped packaging material and ultrasonically sealing the upper part of the bag and the lower part of the bag in the lateral direction by an ultrasonic sealing mechanism, the center of the sealed part is cut with a cutter. Disconnect.
  • the ultrasonic sealing mechanism sandwiches the packaging material between the horn and the anvil, and ultrasonically vibrates the horn to seal the packaging material.
  • a horn and an anvil are attached to each of a pair of rotating bodies, and the horn and the anvil are cylindrical while rotating.
  • the packaging material is sandwiched along the direction orthogonal to the conveying direction of the packaging material and ultrasonically sealed.
  • a horn is composed of a horn body and a plurality of support portions extending from the horn body, and the plurality of support portions are fixed to a common pressure member.
  • a force is applied to both ends of the pressure member, so that the horn is pushed toward the anvil and the packaging material is sandwiched.
  • both ends of the horn are also pressed through the support portion, and the horn may be bent.
  • the horn and the anvil may come into contact with each other, and the sealing performance and durability of the bag may be reduced.
  • An object of the present invention is to provide a bag making and packaging machine capable of preventing contact between a horn used for ultrasonic sealing and an anvil.
  • the bag making and packaging machine fills a tube-shaped packaging material with an article to be packaged and seals it.
  • This bag making and packaging machine includes an ultrasonic sealing mechanism, a horn support, and a pressure unit.
  • the ultrasonic sealing mechanism sandwiches the packaging material with a horn and an anvil and applies ultrasonic vibration to the packaging material to seal the packaging material in the width direction.
  • the horn support supports the horn.
  • the pressurizing unit pressurizes the horn support and pushes the horn toward the anvil.
  • the horn has a horn main body and a plurality of support portions.
  • the horn body sandwiches the packaging material with the anvil.
  • the plurality of support portions extend from the horn body and are arranged in the width direction.
  • the horn support includes a first support member, a second support member, and a connecting member.
  • a plurality of support portions are fixed to the first support member. Both ends of the second support member are pressurized by the pressure unit.
  • a connection member connects the 1st center part which is the center part of the 1st support member, and the 2nd center part which is the center part of the 2nd support member.
  • the first center part is located between a pair of fixing parts to which support parts at both ends in the width direction are fixed.
  • the horn support includes a first support member connected to a plurality of support portions extending from the horn body, and a second support member whose both ends are pressurized during ultrasonic sealing. Have.
  • the first support member is connected to the second support member via a connection member.
  • both end portions of the second support member are pressurized by the pressurizing unit, but the first support member is not directly pressurized by the pressurizing unit. Therefore, at the time of ultrasonic sealing, the first support member is difficult to bend due to pressurization of the horn support.
  • the bag making packaging machine can avoid that the both ends of a horn contact an anvil at the time of ultrasonic sealing. Therefore, the bag making and packaging machine according to the present invention can prevent contact between the horn and the anvil used for ultrasonic sealing.
  • the first central portion preferably has a smaller width than the packaging material sandwiched between the horn and the anvil.
  • the bag making and packaging machine according to the present invention can prevent contact between the horn and anvil used for ultrasonic sealing.

It is easy to bend. Accordingly, when the horn support 171 shown in FIG. 12 is used, both ends of the first horn 51a come into contact with the first anvil 51b due to the bending of the first horn 51a when the cylindrical film Fc is laterally sealed. The first horn 51a and the first anvil 51b may be damaged.
  • the 1st center part 73a of the 1st support member 73 is located between a pair of edge part fixing
  • the first central portion 73a of the first support member 73 may be positioned between both ends of the tubular film Fc sandwiched between the first horn 51a and the first anvil 51b.
  • FIG. 13 is a schematic plan view of a horn support 71 attached to the horn unit 51 in this modification.
  • components other than the connecting member 75 of the horn support 71 are the same as those in FIG.
  • the horn support 71 is shown in a hatched area.
  • the lateral width W1 of the connecting member 75 of the horn support 71 is smaller than the lateral width W2 of the tubular film Fc.
  • both ends of the second support member 74 receive a direct force from the pressurizing unit 72, but the first support member 73 does not receive a direct force from the pressurizing unit 72. . Therefore, even when the pressurizing unit 72 pressurizes the horn support 71 during the horizontal sealing of the tubular film Fc, the first support member 73 is not easily bent.

  • FIG. 14 is a schematic plan view of the horn support 71 attached to the horn unit 51 in the present modification. 14, components other than the connecting member 75 of the horn support 71 are the same as those in FIG. In FIG. 14, the horn support 71 is shown in a hatched area.
  • the first center portion 73 a of the first support member 73 is a portion between the pair of center fixing portions 73 c of the first support member 73.
  • the pair of central fixing portions 73 c are portions to which two resonators 513 except for the resonators 513 at both ends in the left-right direction are fixed, among the four resonators 513 of the horn unit 51.
  • the first central portion 73a is a portion to which the connecting member 75 is connected. Therefore, as shown in FIG. 14, the width W1 of the connecting member 75 in the left-right direction is smaller than the interval W3 between the two resonators 513 fixed to the pair of central fixing portions 73c.
  • both ends of the second support member 74 receive a direct force from the pressurizing unit 72, but the first support member 73 does not receive a direct force from the pressurizing unit 72. . Therefore, even when the pressurizing unit 72 pressurizes the horn support 71 during the horizontal sealing of the tubular film Fc, the first support member 73 is not easily bent.

Abstract

La présente invention a pour but de fournir une machine d'emballage de formation de sacs pouvant empêcher un contact entre le bras et l'enclume qui sont utilisés dans un scellement à ultrasons. Pour atteindre ce but, l'invention porte sur une machine d'emballage de formation de sacs (1) qui est pourvue d'un mécanisme de scellement transversal (17), d'un support de bras (71) et de sections de pressage (72). Le support de bras (71) comprend un premier élément de support (73), un second élément de support (74) et un élément de liaison (75). De multiples résonateurs (73) sont fixés au premier élément de support (73). Les deux extrémités du second élément de support (74) sont pressées par les sections de pression (72). L'élément de liaison (75) relie une première section centrale (73a), qui est la section centrale du premier élément de support (73), à une seconde section centrale (74a), qui est la section centrale du second élément de support (74). La première section centrale (73a) est située entre une paire de sections de fixation d'extrémité (73b) auxquelles sont fixés les résonateurs (513) aux deux extrémités dans la direction de la largeur.
