Description

  The present invention relates to a horizontal pillow packaging apparatus and a packaging method thereof for continuously packaging an article to be packaged in a film while making the film into a cylindrical shape.

Conventionally, as a packaging device of this type, for example, as a general horizontal pillow packaging device, a guide mechanism for guiding a film drawn from an original roll is provided, and two belt-like films drawn through this guide mechanism are used. The folded product is guided in a folded state, and the package is supplied into the tubular film while forming the bag into a tubular shape via the former, and the side ends of the tubular film that has supplied the packaged material are paired with each other. The cylindrical film is transported while being sandwiched by a transport mechanism composed of a supply roller, and the side edges of the cylindrical film sent out by the transport mechanism are sealed with a center seal mechanism composed of a pair of seal rollers. The cylindrical film heat-sealed in the shape is sealed by the end seal mechanism in the direction perpendicular to the film conveyance direction, Heat sealing are to the packaging apparatus is known as out after cutting by successively cutting mechanism packaging bag encapsulating material to be packaged (e.g., Patent Document 1, see Patent Documents 2.).
Japanese Utility Model Publication No.57-6322 Japanese Examined Patent Publication No. 5-75616

  By the way, in the conventional horizontal pillow packaging apparatus which consists of patent document 1 mentioned above, patent document 2, etc., the packaging machine may have to be stopped for some reasons during operation of the packaging machine. For example, the film transport may be temporarily stopped by connecting the film due to film breakage, replacing the raw roll, preparing to supply the packaged goods, or maintaining the packaging machine equipment. If the film is held while being sandwiched by a seal roller that forms a pair of center seal mechanisms at times, there is a problem that the film is heated and melted to damage the film.

  Therefore, when the film transport is stopped, that is, in the operation by a series of packaging work process of the package, the film feed is stopped when the end seal mechanism is operated, and the heat sealing is performed in the width direction of the film. If there is no problem at the time of stopping, but the packaging machine has to be stopped for some reason as described above, the film is pressed by a pair of seal rollers provided in the center seal mechanism. It is necessary to release the pinching state so that the film is released from the pinching state.

  Even if the pair of seal rollers provided in the center seal device is maintained in an open state, depending on the problem of the distance between the seal roller and the film or the material of the film, the radiant heat from the seal roller propagates to the film, The film may be partially shrunk by heat or deformed by melting. As a result, the pair of seal rollers that maintained the open state are restored when the packaging device is restarted (at the time of startup), and the film is fed with the pair of seal rollers at the same time as the film is fed. At that time, if the film itself is deformed as described above, the position where the film is sandwiched by the seal roller may be deviated from the normal state, and the film feed direction is normal horizontal. As a result, it may not be possible to heat-seal in a state where it is neatly arranged in a cylindrical shape, resulting in poor sealing, or pinching with a sealing roller due to shrinkage of the film May not be able to seal well and may fail, resulting in a lack of stability at startup. That.

  The present invention pays attention to the conventional problems, and in the horizontal pillow packaging apparatus and its packaging method, the film is stabilized by a pair of seal rollers provided in the center seal mechanism even after the temporary packaging apparatus is stopped. In order to provide a horizontal pillow packaging apparatus and a packaging method thereof that can sandwich and feed out an appropriate position, a pair provided in the center seal mechanism after a lapse of a predetermined time when the film feeding by the transport mechanism is stopped. The pair of sealing rollers that perform the opening operation of the sealing rollers that form a pair and after the predetermined feeding amount of the film due to the conveying operation of the conveying mechanism or at the time of the conveying operation of the conveying mechanism when starting or restarting The most important feature is that the film is returned to a state where it can be sealed by being sandwiched with respect to the film.

  In the horizontal pillow packaging apparatus and the packaging method according to the present invention, the pair of seal rollers provided in the center seal mechanism are opened after a predetermined time has elapsed when the film feeding by the transport mechanism is stopped, and at the time of starting or restarting. When starting, after the predetermined feeding amount of the film due to the conveying operation of the conveying mechanism or after the elapse of a predetermined time due to the conveying operation of the conveying mechanism, the paired seal rollers are clamped to the film and returned to a sealable state. As a result, even if the film may be partially shrunk by heat from the center seal mechanism or deformed by melting, it will be paired with the center seal mechanism at start-up or restart. Before sandwiching the film with the seal roller, the film is fed first by the transport mechanism. After it has been taken out, it can be sent out while being heat-sealed with a pair of seal rollers sandwiched in a predetermined position, which makes it possible to perform center sealing in a stable state. Can be achieved.

  The present invention relates to a horizontal pillow packaging device capable of stably feeding a film with a pair of seal rollers provided in a center seal mechanism even after the temporary packaging device is stopped, and feeding it at an appropriate position. For the purpose of providing the packaging method, when the packaging device is started or restarted, the amount of film fed by the transport mechanism is counted, and when a predetermined length is fed out, the pair provided in the center seal mechanism is provided. The film is carried out in a stable state while being formed into a cylindrical shape while being heat-sealed by being sandwiched from both sides of the film by a sealing roller. Alternatively, when the packaging device is started or restarted, the film is sandwiched from both sides of the film by a pair of seal rollers provided in the center seal mechanism after a predetermined time elapses from the start of the transport operation of the transport mechanism. The film is sent out in a stable state while being formed into a cylindrical shape while being sealed.

  Hereinafter, as a packaging apparatus according to the present invention, a packaging apparatus of a horizontal positive pillow type will be described as an example.

  FIG. 1 to FIG. 7 show a first embodiment of the present invention. In this first embodiment, a package with the contents placed in a tray is fed, and the package is wrapped with a film. A pillow packaging apparatus and its packaging method will be described as an example.

  In the figure, a machine frame 1 of a horizontal pillow packaging apparatus is provided with a roll holding mechanism 2 that rotatably supports an original roll R, and a belt-like film is formed from the original roll R supported by the roll holding mechanism 2. F is drawn and guided by the guide mechanism 3, and the belt-like film F drawn through the guide mechanism 3 is folded back by the bag-making mechanism 4 made of a former so that the film F is formed into a cylindrical shape. The side edge portions of the tubular film F folded back by 4 are transported by the transport mechanism 5, and the tube folded by the bag making mechanism 4 in synchronization with the transport operation of the film F by the transport mechanism 5 For example, an article W to be packaged with the contents placed in a tray is supplied and guided through a supply mechanism 6 including a conveyor or the like in the film F.

  Further, the side edge portions of the cylindrical film F sent out by the transport mechanism 5 are sealed and closed in a cylindrical shape by a pair of seal rollers 7A (seal members) provided in the center seal mechanism 7, and the center seal mechanism. An end seal mechanism 8 is provided for sealing the tubular film F heat-sealed in a tubular shape by 7 in a direction perpendicular to the film transport direction. The packaging bags P enclosing the articles to be packaged W formed by the seal mechanisms 7 and 8 are individually separated and sent out by the cutting mechanism 9, and the separated and sent-out packaging bags P are composed of a carry-out conveyor or the like. It is configured to be carried out by the mechanism 10.

  Further, as the film F transport mechanism 5 described above, a pair of supply rollers 5 </ b> A that are positioned on the front side of the center seal mechanism 7 and transport while sandwiching the side edge portions of the film F are provided. A pair of carry-out rollers 5 </ b> B are provided on the rear side of the mechanism 7 to form a pair for feeding the cylindrical film F sealed by the center seal mechanism 7.

  In this embodiment, in such a horizontal pillow wrapping apparatus, the center seal mechanism 7 is a sandwich seal mechanism in which a cylindrical film F is pressed and sandwiched and heat-sealed while being transported by the transport mechanism 5. That is, it is configured as a roller-sealing type center seal mechanism in which the lower end portion of the cylindrical film F is pressed and clamped from the left and right outer sides by a pair of center seal seal rollers 7A.

  In this case, each of the seal rollers 7A arranged in a pair is rotatably supported on the center seal holding plate 12 with the rotation support shaft 11 serving as a rotation fulcrum serving as a shaft center. Is provided with a transmission gear 13 coaxially.

  Each center seal holding plate 12 is provided so as to be able to swing and move in the horizontal direction with respect to each fulcrum shaft 14. As a result, the pair of seal rollers 7A approach and separate from each other with the fulcrum shaft 14 as a base point. It is provided to be movable. In this embodiment, the paired seal rollers 7A are biased so as to be opened via the springs 15 with the fulcrum shafts 14 as base points, and at the time of operation of the packaging device, that is, at the time of activation of the packaging device. The center seal holding plates 12 disposed on both sides of the conveyance region of the tubular film F against the urging force of the spring 15 are pressed and urged so as to approach the tubular film F side by the operation of each cylinder 16. The seal roller 7A presses and urges the tubular film F through the center seal holding plate 12 to enable heat sealing. (See Figure 2)

  Further, when the packaging apparatus is not operating (when stopped), that is, when the feeding of the film F by the transport mechanism 5 is stopped, the cylinder 16 constituting the opening / closing means is configured so that the seal rollers 7A provided in the center seal mechanism 7 are opened. The seal roller 7A is provided so as to maintain an open state by the urging force of the spring 15 by performing a return operation so as to stop the pressing urging force. (See Figure 3)

  Each fulcrum shaft 14 that supports each center seal holding plate 12 so as to be swingable is passed through a transmission gear 17, and each transmission gear 17 is always in mesh with the transmission gear 17. The transmission gear 13 provided on each center seal holding plate 12 is kept in mesh.

  An intermediate transmission gear 18 that meshes with one of the transmission gears 17 is provided, and a transmission pulley 20 is attached to a support shaft 19 of the intermediate transmission gear 18. An idle pulley 21 for transmitting the rotation and a transmission pulley 22 for transmitting the rotation to the drive source side described later are provided.

  In the first embodiment, the pair of seals paired with the transport mechanism 5 including the supply roller 5A positioned on the front side of the pair of center seal mechanisms 7 and the unloading roller 5B positioned on the rear side of the center seal mechanism 7. A motor 23 is provided as a drive source for rotationally driving the center seal mechanism 7 including the roller 7A.

  Further, the transport mechanism 5 includes a support shaft 24 on one side of a pair of supply rollers 5A located on the front side of the center seal mechanism 7 and one side of a pair of carry-out rollers 5B located on the rear side of the center seal mechanism 7. Pulleys 27, 28, and 29 are attached to the respective support shafts 24 and 25 and the rotation shaft 26, respectively, on the support shaft 25 and the rotation shaft 26 of the motor 23 serving as a drive source. A pulley 20, an idle pulley 21, a transmission pulley 22, and an endless belt 30 are stretched between the pulleys 27, 28, and 29. At this time, the transport device 5 (supply) is driven by the rotational drive of the motor 23. The roller 5A, the carry-out roller 5B) and the center seal mechanism 7 (seal roller 7A) are passed through an endless belt 30 laid around a pulley 29 provided on the rotating shaft 26 of the motor 23. And it is configured so as to be rotated through each pulley 20,21,22,27,28 Te.

  Further, when the horizontal pillow packaging apparatus is stopped, that is, when the feeding of the film F by the transport mechanism 5 is stopped, in this first embodiment, the pair of seal rollers 7A provided in the center seal mechanism 7 are opened and closed after a predetermined time t0 has elapsed. The cylinder 16 as an opening / closing means opens and closes a pair of seal rollers 7A after a predetermined time t1 has elapsed due to the transfer operation of the transfer mechanism 5 when the horizontal pillow packaging apparatus is started or restarted. There is provided a control unit 31 including a timer mechanism 31A for returning to a state in which the film F can be sandwiched and sealed by operation.

  Each center seal holding plate 12 resists the urging force of the spring 15 by the operation of the cylinder 16 which is an opening and closing means that can open and close the paired seal rollers 7A based on a signal from the control unit 31. With the fulcrum shaft 14 as a base point, it is provided so as to be able to open and close, and the seal roller 7A is opened and closed as the center seal holding plate 12 moves.

  The end seal mechanism 8 includes end seal members 8A and 8B which are located on the downstream side of the center seal mechanism 7 and perpendicular to the transport direction of the tubular film F, in this embodiment, in the vertical direction. A cutter blade 9A, which is a cutting mechanism 9 for the film F, is disposed on one end seal member 8A side.

  Therefore, in the end seal mechanism 8 in this embodiment, when the pair of end seal members 8A and 8B which are vertically opposed to each other are operated and heat-sealed along the width direction of the tubular film F, the packaging film F The feeding bag is intermittently stopped, and the packaging bag P enclosing the article to be packaged W is cut along the width direction of the film F by the cutter blade 9A provided in the cutting mechanism 9 while the film feeding is stopped by the heat sealing. Then, the cut and individually separated packaging bags P are intermittently sent out via the carry-out mechanism 10, and the next packaging bag P in which the packaged object W is enclosed in the waiting cylindrical film F is also conveyed. It is configured to be sequentially fed by intermittent feed of the mechanism 5.

In the above-described configuration, a series of basic packaging operations of the horizontal pillow packaging apparatus and operations of the transport mechanism 5 and the center seal mechanism 7 which are main parts of the present invention will be mainly described.
First, the strip-shaped film F drawn and guided from the raw roll R by the guide mechanism 3 is supplied while being intermittently pulled out in accordance with the sealing operation interval of the end seal mechanism 8 and is intermittently pulled out. F is guided in the form of a cylinder while being folded back into a cylinder by a bag-making mechanism 4 made of a former.

  Subsequently, the side edge portions of the tubular film F folded back by the bag making mechanism 4 are intermittently sandwiched between a pair of supply rollers 5A and a pair of carry-out rollers 5B provided in the transport mechanism 5. While being conveyed, in synchronism with the conveying operation of the film F by the conveying mechanism 5, for example, the contents in a tray are provided in the cylindrical film F folded by the bag making mechanism 4 via a supply mechanism 6 including a conveying conveyor. The article W to be packaged is intermittently supplied and guided.

  Further, the side edge portions of the cylindrical film F intermittently sent out by the transport mechanism 5 are sealed and closed in a cylindrical shape by a pair of seal rollers 7 A provided in the center seal mechanism 7, and the center seal mechanism 7. Is heat-sealed in a cylindrical shape.

  In addition, the tubular film F heat-sealed in a tubular shape is intermittently fed into an end seal mechanism 8 that seals in a direction orthogonal to the film conveying direction, and a pair of end seal members 8A and 8B that are opposed vertically are operated. The packaging bag P that is heat-sealed along the width direction of the tubular film F and encloses the heat-sealed article W to be packaged is individually separated and sent out by the cutter blade 9A of the cutting mechanism 9 and separated. The delivered packaging bag P is intermittently carried out by a carry-out mechanism 10 including a carry-out conveyor.

  Incidentally, as described above, in a series of continuous packaging operation steps of the horizontal pillow packaging apparatus, there is a case where the packaging machine has to be stopped for convenience during operation of the packaging machine. For example, film replenishment work by connecting films due to film breakage, replenishment and replacement work of the raw roll R, confirmation of the state of the packaging seal, confirmation and adjustment of the seal cutting position, or supply preparation work for feeding the package W, and packaging machine The conveyance operation of the film F may be temporarily stopped by maintenance inspection work.

  In this case, in the first embodiment of the present invention, when a stop signal is input by operating a stop switch (not shown) provided on the operation panel of the packaging device, the transfer mechanism 5 is provided. The rotational drive of the motor 23 that rotationally drives the paired supply roller 5A and carry-out roller 5B is stopped, and at this time, the center seal mechanism 7 is passed after a predetermined time t0 has passed through the control unit 31 provided in the packaging device. The pistons of the cylinders 16 are retracted by the return operation of the cylinders 16 serving as opening / closing means between the pair of seal rollers 7A provided on the center, and the pressed center seal holding plates 12 are opened with the fulcrum shaft 14 as a base point. As a result, each seal roller 7A supported on each center seal holding plate 12 is opened, so that it is sandwiched between the seal rollers 7A. Which do the film F is released from the contact state by the pressure of the sealing roller 7A. (Refer to the timing charts of FIGS. 3, 5 and 7)

  Since the film F is not directly pressed and heated by the non-contact state with the seal roller 7A, the phenomenon of damaging the film F as much as possible depends on the material (property) of the film F. It becomes possible to suppress.

  In addition, after the packaging machine is stopped, when a start signal is input by operating a switch (not shown) provided on the operation panel at the time of starting or restarting the horizontal pillow packaging device, the pair provided in the transport mechanism 5 is turned on. The motor 23 for rotating the supply roller 5A and the carry-out roller 5B is operated. Since the supply roller 5A and the carry-out roller 5B of the transport mechanism 5 are rotationally driven by the rotation of the motor 23, the film F is fed out. Thereby, the film F location facing the 7 A location of the seal roller is sent in advance in the carry-out direction by driving the transport mechanism 5. (Refer to the timing chart in FIG. 7)

  In addition, after a predetermined time t1 has elapsed due to the transport operation of the transport mechanism 5, the pair of seal rollers 7A provided in the center seal mechanism 7 is operated by an opening / closing means via a control unit 31 having a timer mechanism 31A. As a result, the pistons of the cylinders 16 are pressed and the center seal holding plates 12 are closed with the fulcrum shaft 14 as a base point, whereby the seal rollers 7A supported on the center seal holding plates 12 are closed. Therefore, the film F is sent out in a stable state while being sandwiched between the seal rollers 7A. (Refer to the timing charts of FIGS. 2, 4 and 7.)

  At this time, the positional relationship of the film F being sandwiched and fed by the respective seal rollers 7A is such that the film F is sandwiched and fed after a predetermined time t1 due to the transport operation of the transport mechanism 5 in advance. Is transported to a position far away from the film F location facing.

  In this way, since the film F is fed in advance in the unloading direction by driving the transport mechanism 5, the film F portion that has been easily hurt by heat against the state adjacent to the seal roller 7 A is fed forward. Even when F partially shrinks due to heat from the center seal mechanism 7 or is deformed due to melting, when it is sent out while being heat sealed by the center seal mechanism 7 at the time of start-up or restart, It can be sent out while pinching an unaffected part, and the center seal can be performed in a stable state.

  Further, in the first embodiment, when the packaging device is stopped, a pair provided in the center seal mechanism 7 is made after a lapse of a predetermined time t0 after the packaging device is stopped via the control unit 31 provided in the packaging device. The seal roller 7A is set to be opened, but the material (property) of the film F, for example, the film F which is weak against heat, opens the center seal mechanism 7 almost simultaneously with the temporary stop of the packaging device. In addition, after the open state, a delay until a predetermined time t1 elapses after the film F is fed by the supply roller 5A and the carry-out roller 5B of the transport mechanism 5 at the time of starting or restarting. The time is determined by the timer mechanism 31A provided in the control unit 31 according to various conditions such as the feeding speed of the film F or the material of the film F. It is those that may be set in mind.

  The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist of the present invention. In the first embodiment, the transport mechanism is activated when the packaging apparatus is started or restarted. The supply roller 5A and the unloading roller 5B transport the film F, and after a predetermined time t1 has elapsed from the transport operation, the pair of seal rollers 7A provided in the center seal mechanism 7 are sandwiched between the film F and heated. For example, although not shown, the supply roller 5A and the carry-out roller provided in the transport mechanism 5 are adjusted by the time setting of the timer mechanism 31A provided in the control unit 31 so as to return to a sealable state. After a predetermined feed amount of the film F has elapsed by counting the number of revolutions of 5B or the number of revolutions of the motor 23 that rotationally drives the transport mechanism 5 By providing a control unit 31 having a pulse counter function for returning to a state in which it can be sealed by being sandwiched between the film F by a pair of sealing rollers 7A, the rotational speed of the transport mechanism 5 and the motor 23 are provided. Is detected by a pulse counter function and converted into a feed amount of the film F. After a predetermined feed amount of the film F has elapsed, the pair of seal rollers 7A provided in the center seal mechanism 7 is used to form the film F. The film F can be sent out in a stable state while being formed into a cylindrical shape while being heat sealed and sandwiched from both sides.

  Therefore, even if the film F is partially contracted by heat from the center seal mechanism 7 or deformed by melting due to the temporary stop state, the center seal mechanism 7 is not activated at the time of starting or restarting. Before the film F is sandwiched between the provided pair of seal rollers 7A, the film F is first sent out by the transport mechanism 5, and then heat seal is performed by sandwiching a predetermined position of the film F by the pair of seal rollers 7A. The center seal can be performed in a stable state.

  Further, in the horizontal pillow packaging method and the horizontal pillow packaging device, as the opening / closing means for opening the pair of seal rollers 7A provided in the center seal mechanism 7 after a predetermined time t0 has elapsed when the feeding of the film F by the transport mechanism 5 is stopped. In the embodiment, the pair of seal rollers 7A that are opened / closed by the opening / closing means comprising the cylinder 16 via the center seal holding plate 12 is provided so as to be movable in an open / closed manner. The center seal holding plate 12 disposed opposite to the cam mechanism can be opened and closed, or each seal roller 7A provided in the center seal mechanism 7 can be directly opened and closed through the link mechanism in accordance with the movement of the electromagnetic solenoid. In some cases, one side of the sealing roller It may be provided only openably A.

  In the embodiment, the driving means for rotationally driving the transport mechanism 5 and the center seal mechanism 7 is provided so as to be driven by the single motor 23. However, the driving means may be provided individually, In some cases, a motor for rotationally driving the supply roller 5A and the carry-out roller 5B of the transport mechanism 5 may be provided independently.

  Further, the feeding and stopping of the film F by the transport mechanism 5 is set so that the operation of the transport mechanism 5 is synchronized with the operation of the guide mechanism 3 that pulls out and guides from the original roll R to carry out and stop the film F. May be.

  Further, in the embodiments, the description has been given by taking the horizontal normal pillow type packaging apparatus as an example, but the present invention can also be applied to the reverse pillow type, and the same effect can be obtained.
