Description

  The present invention relates to a film delivery apparatus that feeds a long belt-like film from a film roll wound with a long belt-like film to a labeling device or the like.

  Cylindrical labels formed of synthetic resin films, such as shrink labels and stretch labels attached to bottles, etc., are long strip labels that are folded into a sheet with a number of labels connected continuously. It is common to mount the forming substrate on a bottle or the like while forming individual labels by sequentially cutting in a labeling device. Such a long strip-shaped label forming substrate is usually a paper tube. A base material roll wound around in the form of a roll is set in a base material delivery device of a labeling system, and is sent out to the labeling device while being continuously fed out from the base material delivery device.

As shown in (b), the apparatus waits in a state in which the end portion of the tubular film F is positioned at the film connection position γ. At this time, the standby position of the end portion of the delivered tubular film F is held in a horizontal state by the inner guide 44.

  Subsequently, as shown in FIGS. 26A and 26B, the unit main body 25 of the setting unit 24 that positions the tubular film F at the film set position β1 or the film set position β2 is formed on the tubular film F. When the right end of the beginning end of the tubular film F starts moving to the position corresponding to the suction pad 422a of the opener 422, the pair of gripping arms 422b of the opener 422 are closed, so that the suction pad 422a is closed. After gripping the right end of the starting end of the tubular film F, the suction pad 422a sucks and holds the right end of the starting end of the tubular film F by starting suction, as shown in FIGS. 27 (a) and 27 (b). Thus, in a state where the right end of the starting end portion of the tubular film F is sucked and held, the opener 422 is fed together with the unit body 25 to the tubular film F. Start moving to the outgoing route side.

  Thereafter, as the opener 422 moves toward the delivery path side of the tubular film F, the grip arm 422b opens, and the overlapping portions at the right end at the start end of the tubular film F are separated from each other. ), As shown in (b), the end of the sent-out tubular film F positioned at the film connection position γ is inserted into the start end of the sent-out tubular film F separated from each other. It will follow.

  And as shown to the same figure (a), (b), the right end of the tubular film F which has left | separated is installed in the center of the width direction of the inner guide 44 between the inner guide 44 and the cutting | disconnection unit 41. When it is detected by the film detection sensor 423, the suction pad 422a releases the suction holding of the tubular film F, and the unit body 25 further moves by a distance of 1/2 the width of the tubular film F and stops. To do. At this time, as shown in FIGS. 29 (a) and 29 (b), the terminal portion of the tubular film F that has been sent out is completely sandwiched between the starting end portions of the tubular film F before being sent out. .

  In this way, when the end portion of the tubular film F that has been sent is sandwiched between the start ends of the tubular film F that has not been sent, the tape adhering mechanism 46 has the upper tape suction as shown in FIG. As the head 463 turns 90 ° downward and the lower tape suction head 463 turns 90 ° upward, the adhesive surface of the adhesive aluminum tape AT sucked and held by each tape suction head 463 is Since the start end of the tubular film F before sending is opposed to the tubular film F, F sandwiching the terminal end of the sent tubular film F, with the pair of upper and lower tape suction heads 463 facing each other. When the boundary portion between the tubular films F and F is sandwiched, as shown in FIG. 29 (b), an adhesive aluminum tape is adhered to the boundary portion, and the cylindrical film that has been sent out is attached. And Lum F and the tubular film F before delivery are joined to each other.

  Thereafter, as shown in FIG. 10B and FIG. 11B, the driving roller 256 and the driven roller 257 that sandwiched the tubular film F before delivery between the guide plate 253 and the guide plate 253 are separated. Thereafter, as shown in FIGS. 30A and 30B, the unit main body 25 starts to move back to the initial position side, and the tape suction heads 463 sandwiching the boundary portion between the tubular films F and F are separated from each other. Then, when the individual driving unit 16 of the rotation driving mechanism 12 constituting the film feeding means 10 rotates the next film roll R, the cylindrical film F is fed out from the film roll R, and the cylindrical film F starts to be sent to the labeling apparatus side by the film sending means 30. When the unit body 25 is retracted to the initial position, the film set is set so that the setting unit 24 on the lower side thereof matches the delivery level of the cylindrical film F in preparation for the next connecting operation of the cylindrical films F and F. The entire means 20 is raised by a predetermined height.

  As described above, in the film delivery apparatus 1, the tubular film F is pulled out from the plurality of film rolls R set in a multi-stage stacked state at the roll setting positions α1 and α2, and is set to the film setting positions β1 and β2. If the cylindrical film F fed out from one film roll R set at the roll setting position α1 or the roll setting position α2 has been sent out, the end of the cylindrical film F that has been sent out is set in advance. The film connecting means 40 automatically connects the first end portion of the tubular film F drawn from the film roll R before delivery, which is already set at the film setting position β1 or the film setting position β2. After that, the individual driving unit 16 of the film feeding means 10 rotates the next film roll R, so that a new film is formed. Since the tubular film F is unwound from the roll roll R, and the tubular film F starts to be fed to the labeling device side by the film delivery means 30, after a plurality of film rolls are mounted on the reels as in the conventional film delivery device. Further, it is not necessary to perform troublesome setup work such as manually connecting the strip films drawn from adjacent film rolls while stacking them, and the strip films can be sent out efficiently. In particular, when a plurality of film rolls R are stacked and transported or stored, the setting operation of the film rolls R on the film feeding means 10 can be performed more efficiently.

  Moreover, the cylindrical films F and F withdrawn from the adjacent film rolls R and R stacked in multiple stages are not connected in advance as in the conventional film delivery apparatus, and the cylindrical film F from the one film roll R is not connected in advance. At the time when the film roll R is switched, the tubular films F and F are connected to each other when the film roll R is switched. Troubles such as the connection portion being caught are unlikely to occur, and the tubular film F can be smoothly and reliably delivered.

  Moreover, in this film delivery apparatus 1, two sets of film roll groups GR in which a plurality of film rolls R are stacked in multiple stages are set in the film feeding means 10, and from the film roll R of one film roll group GR to the cylinder When the cylindrical film F has been sent out, the cylindrical film F starts to be sent out from the film roll R of the other film roll group GR, so that the cylindrical film F is sent out from the film roll R of the other film roll group GR. In the meantime, one film roll group GR from which all the tubular film F has been delivered is replaced with a new film roll group GR, and the tubular film F pulled out from each film roll R is set by the film setting means 20. The cylindrical film F can be continuously sent out by repeating a series of operations such as the above.

  In particular, in this film delivery apparatus 1, the tubular films F drawn from the plurality of film rolls R set at the roll setting positions α1 and α2 are respectively set to predetermined film setting positions β1 and β2 by the film setting means 20. The transfer unit 42 which is automatically set and the film connecting means 40 has a start end portion in a state where both side edges of the cylindrical film F set at the film setting positions β1 and β2 are opened in advance. Each of them is separated from each other while being sucked and held, and after the end portion of the tubular film F that has been sent out is sandwiched at the start end portion, an adhesive aluminum tape is attached to the boundary portion between the two tubular films F and F by the connection unit 43. By sticking AT, both tubular films F, F were connected to each other, so The starting end of the state where the both side edges of the film F has been cut open in advance without the need of separating manually, can be performed tubular film F, the connection work of F between smoothly and reliably.

  In the above-described embodiment, the adhesive aluminum tape AT is applied to the boundary portion between the tubular films F and F in which the starting end portion of the tubular film F before delivery sandwiches the end portion of the delivered tubular film F. Although the tubular films F and F are connected by sticking, it is not limited to this, For example, the adhesive film in which the outermost layer was formed with the thermoadhesive resin is used as the tubular film. By sticking in advance to the inner surface of the starting end, heat-sealing the overlapping portion of the cylindrical film sandwiching the end of the cylindrical film that has been sent out the end of the cylindrical film before sending, It is also possible to connect the tubular films. However, in that case, it goes without saying that the outer surface of the tubular film F must have thermal adhesiveness to the adhesive tape.

  Moreover, in embodiment mentioned above, although the film roll R which cut off both the side edges in the starting end part of the cylindrical film F beforehand is set to the film delivery means 10, it is not limited to this, A film set When the film setting means positions the cylindrical film pulled out from the film roll set at the position at the film setting position, it is possible to cause the film setting means to automatically cut off both side edges at the start end.

  Moreover, in embodiment mentioned above, it is trying to cut off the both-sides edge in the starting end part of the cylindrical film F diagonally so that the starting end part of the cylindrical film F can be separated, but it is limited to this. The same function can also be exhibited by opening both side edges at the start end of the tubular film F instead of the one.

  In the above-described embodiment, the tubular films F and F are connected to each other in a state where the terminal portion of the tubular film F that has been sent is sandwiched between the start ends of the tubular film F that has not been sent. However, the present invention is not limited to this, and the adhesive tape is attached to the abutting portion in a state where the end portion of the tubular film that has been sent out and the starting end portion of the tubular film before the sending are mutually butted. Of course, it is also possible to connect the tubular films, and in that case, the opener can be omitted.

  In the embodiment described above, the film roll R in which the tubular film F is wound around the paper tube PP is used. However, the present invention is not limited to this, and the tubular film is wound around the plastic tube. It is also possible to use a film roll made only of a cylindrical film without a paper tube or a plastic tube.

  In the above-described embodiment, the film sending apparatus 1 for sending the tubular film F folded into a sheet shape has been described. However, the present invention is not limited to this, and a simple belt-like film or a belt-like sheet is sent. Needless to say, the film delivery apparatus of the present invention can be applied, and in this case, the opener can be omitted.
