Description

  The present invention relates to an article supply device and a packaging machine in a packaging machine.

  As one form of the packaging machine, there is a pillow packaging machine that directly places an article to be packaged directly on a film to be transported, and then forms the film into a cylindrical shape and wraps and packages the article to be packaged. . This type of pillow wrapping machine is disclosed in, for example, Patent Document 1 and has the following configuration.

  First, the belt-like film wound around the raw roll is continuously supplied to the film conveying device, and the belt-like film is conveyed by the film conveying device. Place the items to be packed so that they are evenly spaced. Thereby, a strip | belt-shaped film is conveyed in the state by which the to-be-packaged goods were put on the film conveyance apparatus at equal intervals (packaging pitch), and is supplied to the bag making machine of the next stage.

  When passing through the bag making device, the belt-like film is formed into a cylindrical shape so as to wrap the article to be packaged, thereby forming the cylindrical film. And a to-be-packaged article is conveyed with a cylindrical film. A center seal device and an end seal device are arranged along the conveying direction. The center seal device seals the film polymerization end of the tubular film. The end seal device seals the tubular film in the lateral direction of travel (portion where the front and rear packages are not present) and cuts the portion of the tubular film in which the front package is stored. Is separated from the subsequent cylindrical film to produce a package.

  By the way, when supplying a package by hand to a desired position of the belt-shaped film transported on the film transport device, when a mark indicating the supply position is printed on the belt-shaped film, the printed mark The package can be placed on the basis of On the other hand, when supplying an article to be packaged to a desired position of a transparent belt-like film on which such mark is not printed, a “placing position instruction method for an article to be packaged on a wrapping paper” as shown in Patent Document 1. Can be used. That is, the technique disclosed in Patent Document 1 transports a strip-shaped film on a table including a plurality of light emitting elements such as diodes arranged along the transport direction of the strip-shaped film.

  As a result, as shown in FIG. 1, the light emitted from the light emitting element is transmitted through the belt-like film 1 and displayed as an indication line 2 on the surface of the belt-like film 1. Each of the support lines 2 is disposed so as to extend in a direction crossing the belt-like film 1 (a direction orthogonal to the transport direction), and also moves the drawing position of the instruction line 2 synchronized with the movement of the belt-like film 1. Thereby, the operator who supplies a to-be-packaged object can supply the to-be-packaged object manually for every predetermined pitch by placing the to-be-packaged object 3 between the front and back instruction lines 2.

Japanese Patent No. 3738093

  By the way, as a general form of the pillow wrapping machine, the packaged material is not supplied on the film (strip-shaped film) as described above, but is covered in the film that is formed into a cylindrical shape by a bag making machine. There is a type that sequentially supplies packages. That is, the belt-like film wound around the raw roll is continuously supplied to the bag making machine, and when the bag making machine is passed, the tubular film formed into a cylindrical shape is formed. In addition, an article transporting and supplying device is arranged on the upstream side of the bag making device, and an object to be packaged conveyed at predetermined intervals from the object to be packaged conveying and supplying device is supplied into the bag making device. Accordingly, when the article to be packaged passes through the bag making machine, the article to be packaged is stored at predetermined intervals in the cylindrical film, and the article to be packaged is conveyed together with the cylindrical film. A center seal device and an end seal device are arranged along the conveying direction. The center seal device seals the film polymerization end of the tubular film. The end seal device seals the tubular film in the lateral direction of travel (portion where the front and rear packages are not present) and cuts the portion of the tubular film in which the front package is stored. Is separated from the subsequent cylindrical film to produce a package.

  As this package supply device, there is a device that uses a belt conveyor to manually supply a package on the belt-bear. In a packaging machine of this type using a belt conveyor of this type, the method of Patent Document 1 cannot be used, and there is no means for instructing the placement position of an object to be packaged. Immediately before the supply to the bag making apparatus for that purpose, a device for adjusting the supply timing is separately provided, and the apparatus is supplied to the bag making apparatus at regular intervals within the cylindrical film.

  Further, even the packaging machine described in Patent Document 1 cannot be applied to a non-transparent film. As described above, there are few packaging machines that can be handled by the technique disclosed in Patent Document 1, and there is a problem that the versatility is lacking.

  Furthermore, in the apparatus of Patent Document 1, since there is a packaging object placement position indicating means (a group of diodes arranged in a matrix) having a light emitting function on the lower surface to which the packaging object is supplied, a heavy or hard packaging object If it is accidentally dropped on the indicating means, the indicating means may be damaged or cause a failure.

  Furthermore, in Patent Document 1, since the diode groups arranged in a matrix are used, the indicator line 2 is a straight line extending in a direction orthogonal to the traveling direction, and the indicator line indicating the front end position of the package 3 and the rear end Since the instruction lines indicating the positions are alternately arranged, the interval between the other instruction lines (the instruction lines indicating the front end positions or the instruction lines indicating the rear end positions) is equal to the packaging pitch and is continuous in the front and rear. The interval between the indicator lines indicating the front end position and the rear end position is equal to the length of the article 3 to be packaged. Therefore, for example, when the length of the package is short, as shown in FIG. 1B, in the state where only the instruction line 2 before supplying the package is displayed, which of the x position and the y position is However, there are cases where it is not possible to instantly determine where to supply the packaged items, and there is a problem that the display mode of the supply position may be insufficient.

In order to solve the above-described problems, the present invention includes (1) a transport unit that is disposed on the upstream side of the packaging machine body, transports the packaged article, and supplies the packaged article to the packaging machine body. A light irradiating unit disposed above the conveying unit and irradiating light toward the conveying surface of the package in the conveying unit, the light irradiating unit comprising a laser irradiation device, The laser beam emitted from the laser irradiation device draws a mark indicating the manual supply position of the article to be packaged on the conveyance surface, and advances the mark at the same speed as the article to be packaged in the conveyance means. and than also cause moved, it was assumed to draw a mark indicating the supply position plurality simultaneously. A conveyance means respond | corresponds to the to-be-packaged goods conveyance supply apparatus 14 and the film conveyance apparatus 41 in embodiment. Instead of directly transporting an object to be packaged like the film conveying device 41, an object for conveying an object to be packaged placed on a belt-like film also corresponds to the conveying means for conveying an object to be packaged in the present invention.

  The light irradiating means of the present invention is arranged above the conveying means, and light is irradiated from above to the conveying surface, so that the mark can be drawn regardless of the material (transparent / non-transparent) of the conveying surface. it can. Therefore, the film can be used regardless of the type of film used for packaging and the type of packaging machine (packaged article conveyance and supply device). In other words, even if the transport surface (the film itself used for packaging / the surface of the transport means for transporting the package) is not printed with a mark or the like serving as a guide for the supply position of the package, The packaged items can be reliably supplied to the place manually. Further, since the transport surface is a normal transport means or the like, there is little possibility of damaging the transport means even if an article to be packaged that is heavy or hard falls on the transport surface.

  (2) The mark may include an indication of the placement position of at least one of the front end and the rear end of the packaged object in the transport direction. In this way, it is only necessary to align the front end or the rear end of the package with the position of the mark, so that the alignment can be performed easily. In the embodiment, this mark is realized by, for example, the first mark M1, the second mark M2, the third mark M3, the fourth mark M4, the mark shown in FIG. In the case of the fourth mark M4, in the embodiment, the placement positions of both the front end and the rear end of the article to be packaged are indicated, but only one of the placement positions may be indicated.

  (3) The mark may specify a supply range in the front-rear direction of the package in the transport direction. Since the supply range is specified, it is only necessary to place the article to be packaged within the range, so that the supply range can be easily supplied. In the embodiment, this mark is realized by, for example, the fourth mark M4, the fifth mark M5, the mark shown in FIG. The length of the supply range in the front-rear direction may coincide with the packaged item, or may be longer (allowable).

  (4) The mark may include a display indicating the center of the packaged object in the width direction. This is preferable because alignment in the width direction can be easily performed. This eliminates the need for a product side guide or the like for regulating the width direction on the conveying means. In the embodiment, the display indicating the center in the width direction is realized by the vertical line portion b or the like. (5) The mark includes a T-shaped pattern having a horizontal line portion extending in the horizontal direction and a vertical line portion extending from the horizontal line portion forward or backward in the conveying direction, and the vertical line portion is the packaged object. It is good to set so that it may protrude to the mounting prohibition side. This is preferable because it can be visually intuitionally understood which position on the front end side / rear end side of the package is shown. In the embodiment, this mark is realized by, for example, the first mark M1, the second mark M2, the mark shown in FIG.

  (6) The mark may be a straight line extending in the transport direction, and may indicate a placement prohibited range of the packaged object. In this way, the mark is formed at the place where the packaged goods should not be placed, so that the place where the packaged goods can be placed can be easily understood, and even when the packaged goods are placed on the transport surface, Since the mark continues to be drawn, the placement prohibition range can be confirmed even after the package is supplied.

  (7) The mark may be a square frame that indicates a range in which an article can be placed. If it does in this way, what is necessary is just to supply a to-be-packaged object in the frame, Therefore A supply location can be known at a glance and work can be performed easily. In the embodiment, this mark is realized by, for example, the fifth mark M5.

  (8) The mark may be drawn on the front end side and the rear end side of the package, respectively, and the drawn form may be set differently on the front end side and the rear end side. Different settings include, for example, changing the shape, changing the width of the lines that make up the mark, changing the size of the mark, changing the display color, or flashing one or both (both In the case of flashing both, it is possible to adopt various modes such as changing the pattern). In this way, it is possible to know at a glance whether the drawn mark is on the front end side or the rear end side of the package, and it is possible to suppress the supply position from becoming unknown.

  (9) A packaging machine according to the present invention performs packaging processing on the packaged article supply apparatus according to any one of (1) to (8) above and the packaged article supplied by the packaged article supply apparatus. A packaging machine main body, and the packaged article conveyance and supply device conveys a band-shaped film, and a surface of the band-shaped film serves as a conveyance surface of the packaged object, and the packaged object is packaged together with the band-shaped film. It can be supplied to the body.

  (10) A packaging machine according to the present invention performs packaging processing on the packaged article supply apparatus according to any one of (1) to (8) above and the packaged article supplied by the packaged article supply apparatus. A packaging machine main body, and the packaged article conveyance and supply device includes a belt conveyor device, and a belt surface of the belt conveyor device can serve as a conveyance surface of the packaged material.

  The present invention can correctly display the supply position of an object to be packaged on the conveyance surface regardless of the type of packaging machine or packaging film to be used, and can be surely supplied manually.

  As shown in FIGS. 2 and 3, the horizontal pillow packaging machine 10 used in this embodiment includes a packaging machine main body 11 and a film supply device that continuously supplies a strip-shaped packaging film to the packaging machine main body 11. 12 and a packaged article transport and supply device 14 that is arranged on the upstream side of the packaging machine main body 11 and that supplies the packaged goods 13 to the packaging machine main body 11 at predetermined intervals.

  The film supply device 12 links the output of a drive motor (not shown) (speed-controllable motor such as a servo motor) to the original roll 16 obtained by winding the belt-like film 15 into a roll. Supplying to the packaging machine body 11 at a constant speed while appropriately controlling the rotation speed. Further, various rollers are arranged at predetermined positions from the original fabric roll 16 to the packaging machine body 11, and the belt-like film 15 fed out from the original fabric roll 16 is passed over the rollers, thereby passing through a predetermined path. To the packaging machine body 11. Of course, in the present invention, it is not always necessary to link the drive motor to the raw roll 16, and a feed roller may be provided on the transport path of the packaging film and pulled out. And in this embodiment, although the film supply apparatus 12 has taken the aspect of the reverse pillow packaging machine arrange | positioned under the packaging machine main body 11, this invention arrange | positions a film supply apparatus above a packaging machine main body. Of course, the normal type is also acceptable.

  The to-be-packaged goods conveyance supply apparatus 14 is comprised from the belt conveyor apparatus provided with the pulley 17 arrange | positioned forward and backward, and the endless belt 18 hung over the pulley 17. FIG. The article 13 to be packaged placed on the endless belt 18 moves forward as the endless belt 18 rotates.

  The packaging machine main body 11 includes a bag making machine 20 for making the supplied belt-like film 15 into a tubular film 21, and a belt conveyor 23 for conveying the tubular film 21 disposed on the downstream side of the bag making machine 20. A center seal device 24 installed at a predetermined position above the belt conveyor 23, an upper restraining belt 25 disposed above the belt conveyor 23 and downstream of the center seal device 24, and downstream of the belt conveyor 23. An end seal device 30 disposed and a carry-out conveyor 26 disposed on the downstream side of the end seal device 30 are provided.

  The bag-making device 20 allows the side film edges 15a of the belt-like film 15 to contact (polymerize) with each other by passing the belt-like film 15 continuously supplied from the film feeding device 12, and the tube that has become cylindrical. Bag-like film 21 is made. In addition, the articles to be packaged 13 that are sequentially supplied from the article to be packaged supply apparatus 14 to the packaging machine main body 11 are inserted into the bag making machine 20. Thereby, the article 13 to be packaged supplied to the bag making machine 20 is arranged in the cylindrical film 21 at predetermined intervals. Moreover, in this embodiment, since the film supply apparatus 12 was arrange | positioned under the packaging machine main body 11, both the side edge parts 15a of the strip | belt-shaped film 15 are located above the cylindrical film 21. FIG.

  The center seal device 24 seals both side edge portions 15a of the polymerized belt-like film 15. That is, in this embodiment, the both side edge portions 15 a of the belt-like film 15 are formed so as to protrude below the tubular film 21 by passing through the bag making device 20. Therefore, the center seal device 24 is installed at a predetermined position below the conveyance surface of the tubular film 21. The center seal device 24 includes a pair of disc-shaped center sealers 24a, and heat-seals the pair of center sealers 24a by heating the both side edge portions 15a of the belt-like film 15 from both sides with a predetermined pressure. To do. Thus, the side edge portions 15a are heat-sealed and integrated into a center seal portion. Further, a pinch roller 33 is provided on the upstream side of the center seal device 24 and between the bag making machine 20, and the side edge portions 15 a of the belt-like film 15 are sandwiched between the pinch rollers 33. A conveying force is applied, and both side edge portions 15a are stably guided to the center seal device 24 at the next stage.

  The upper restraining belt 25 is arranged in the immediate vicinity of the upstream side of the end seal device 30 and suppresses the article 13 in the tubular film 21 from being lifted upward so that it can be conveyed while maintaining a horizontal state. ing.

  The end seal device 30 seals and cuts the tubular film 21 in a direction orthogonal to the traveling direction, that is, in a transverse direction. The film part to be sealed / cut is a predetermined position between the front and back objects 13 to be packaged. Thereby, the head part of the cylindrical film 21 is isolate | separated from the subsequent by passing the end seal apparatus 30, and the package body 27 is manufactured.

  Here, in the present embodiment, a package supply position indicating device 40 is provided at a predetermined position above the package transport and supply device 14. For convenience of illustration, FIG. 3 which is a plan view (the same applies to FIG. 11 to be described later) is drawn beside the article transport / supply device 14, but is actually disposed above the belt conveyor 18. ing. The package supply position indicating device 40 is configured using a laser irradiation device. Then, as shown in FIG. 4, the laser beam emitted from the laser irradiation device indicates the supply position at a predetermined position on the endless belt 18 that becomes the conveyance surface of the package object of the package object conveyance supply device 14. A first mark M1 having a predetermined shape (here, a T-shape) is drawn, and the first mark M1 is synchronized with the movement of the endless belt 18 so as to move forward at the same speed as the movement speed of the endless belt. ing. As a result, a certain first mark M1 moves while being drawn at the same position on the endless belt 18.

  In the present embodiment, the package supply position indicating device 40 is configured by using a laser irradiation device and irradiates the laser beam onto the endless belt 18. Even so, it is possible to draw and display a predetermined pattern of marks on the surface of the endless belt 18. Therefore, the operator who supplies the article to be packaged 13 can supply the mark displayed on the endless belt 18 to the correct position with reference to the mark.

  And the 1st mark M1 of this embodiment is T-shaped, and is provided with the horizontal line part a extended in the orthogonal direction with the advancing direction, and the vertical line part b extended in the advancing direction front from the center of the horizontal line part a. And this 1st mark M1 shows the front-end position of the advancing direction of a to-be-packaged object. That is, since all the first marks M1 in the present embodiment are drawn at the front end position of the article 13 on the endless belt 18, the front end of the article 13 is shown in FIG. By placing the article 13 on the endless belt 18 so that the position is along the horizontal line part a of the first mark M1, the article 13 can be supplied manually while positioning.

  Further, as is clear from FIG. 4A, the first mark M1 indicates the front end position of the package 13 in the traveling direction, and the vertical line portion b is located outside the package 13 so It can be clearly and intuitively understood that the mark indicates the front end position of the package.

  In addition, the position of the vertical line portion b is drawn so as to indicate the center position in the width direction of the article 13, so that the alignment of the article 13 with respect to both the front-rear direction and the width direction can be easily performed. it can. In addition, since the vertical line portion b has a pattern extending forward in the traveling direction with respect to the horizontal line portion a, when the package item 13 is placed on the belt conveyor 18, the package item 13 or the operator's hand It is possible to prevent the laser from being interrupted so that part or all of the first mark M1 cannot be seen, and in particular, by continuously drawing the vertical line portion b, the center position in the width direction of the package 13 cannot be determined. Can be prevented.

  In the present embodiment, the first mark M1 is drawn at a location corresponding to the front end position of the article 13 to be packaged, but the present invention is not limited to this, and the first mark M1 is drawn at a location corresponding to the rear end position. Anyway. In this case, as shown in FIG. 5, the second mark M2 has a pattern layout in which the vertical line portion b is formed so as to extend from the center of the horizontal line portion a to the rear side in the heartbeat direction. Thereby, as shown to Fig.5 (a), in the state where a to-be-packaged object does not exist, the vertical line part b is extended in the advancing direction, and the position of the horizontal line part a is intuitively the rear end of the to-be-packaged object. It can be understood that it is a position. As shown in FIG. 5B, even when the article 13 is supplied, the laser beam is not blocked by the article 13 or the like, and the horizontal line portion a and the vertical line portion b are on the belt conveyor 18. The second mark M2 can reliably indicate the position in the front-rear direction and the width direction.

  Furthermore, the predetermined shape indicating the supply position is not limited to the T shape as shown in the above-described embodiments and modifications, and any shape can be adopted. As an example, although not shown in the figure, in the T-shaped pattern shown in FIGS. 4 and 5, it can be a straight line pattern of only the horizontal line part a or a straight line pattern of the vertical line part b.

  In the case of the mark consisting of the pattern of only the former horizontal line portion a, the operator who supplies the package 13 places the package 13 on the endless belt 18 so that the front end or the rear end of the package 13 is combined with the mark. It is possible to manually supply the package 13 while aligning. In addition, the alignment of the package 13 in the width direction is performed by, for example, adjusting the midpoint of the horizontal line portion to the center position in the width direction of the package 13 so that the vertical line portion of the T-shaped mark is aligned. Although it becomes less clear, it can be aligned to some extent.

  Further, in the case of a mark consisting of only the pattern of the latter vertical line part, the operator who supplies the article to be packaged 13 puts the front end or rear end of the article to be packaged 13 on the covered part so that the front end or rear end of the article to be packaged is aligned with the rear end or front end of the linear part. By placing the package 13 on the endless belt 18, the package 13 can be manually supplied while aligning. In this case, by setting so that the position of the vertical line portion is drawn so as to be the center position in the width direction of the package, alignment in the width direction can be performed easily and reliably.

  In either case, just looking at the shape of the mark, such as a T-shape, it is difficult to understand intuitively whether the front end or the rear end of the package is shown. This can be handled by informing the operator in advance.

  As another example of the pattern shape of the mark, as shown in FIG. 6, a cross-shaped third mark M3 in which the horizontal line part a and the vertical line part b cross can also be used. The third mark M3 indicates the front end position of the article 13 to be packaged. Thereby, even if the operator who supplies a packaged object supplies a packaged object on the belt conveyor 18 in which the packaged object is not put as shown to Fig.6 (a), each 3rd mark M3 is Since it is known that the front end position of the article to be packaged is indicated, the front end position of the article to be packaged 13 is along the horizontal line portion a of the third mark M1, and the center position in the width direction is the vertical line of the third mark M3. By placing the article to be packaged 13 on the endless belt 18 so as to match the part b, the article to be packaged 13 can be manually supplied while aligning (see FIG. 6B).

  Further, as is clear from FIG. 6 (b), the portion extending from the inner horizontal line portion a of the vertical line portion b to the rear in the traveling direction is blocked by the package object 13 (in practice, the surface of the package object is irradiated). The vertical line portion b at the front portion in the traveling direction is drawn on the endless belt 18, so that it is confirmed whether or not the package 13 is positioned at the center in the width direction even after and after placing. can do.

  Of course, in the case of such a cross-shaped mark, not only the front end position of the article 13 to be packaged as shown, but the rear end position may be indicated. In addition, it is difficult to understand intuitively whether the front end or the rear end is indicated simply by looking at the shape of the mark, such as a T-shape, but the supply / worker is informed in advance of which is indicated. We can cope with it.

  As another form, as shown in FIG. 7, the fourth mark M4 may be formed only from the vertical line portion b extending in the traveling direction. In this case, the front and rear ends of the vertical line portion b are set so as to indicate the rear end position and the front end position of the article to be packaged positioned in the front and rear, respectively. As a result, a blank space K without a line formed between the front and rear vertical line portions b becomes the supply position of the article to be packaged. In this example, the length of the space portion K (the distance between the front and rear vertical line portions b) is set equal to the length of the article to be packaged.

  Therefore, even if the operator who supplies a package is to supply a package on the belt conveyor 18 on which the package is not placed as shown in FIG. By placing the article 13 on the endless belt 18 so that the end portion is the front end / rear end position of the article to be packed and fit in the space K, the article 13 is supplied manually while being aligned. (See FIG. 7B). Furthermore, by setting so that the position of the vertical line portion b is drawn so as to be the center position in the width direction of the packaged object, the alignment in the width direction when supplying the packaged object 13 can be performed easily and reliably. It can be carried out.

  In addition, the supply position of the package 13 may be allowed to deviate to some extent in the front-rear direction. In such a case, in consideration of the deviation (play), the space portion K is set to be wider than the length of the object to be packaged 13, and the operator is set to supply the object to be packaged 13 in the space portion K. It is also good. In other words, the article to be packaged 13 is set to be in a state where it cannot be supplied in a state where it overlaps with a part of the vertical line part b, although it is sufficient to contact the tip of the vertical line part b.

  FIG. 8 shows still another form of the mark. The fifth mark M5 is formed from a rectangular frame. The area surrounded by the rectangular frame indicates the supply area of the package 13. In this example, since there is a certain amount of play in the front-rear and left-right directions as the supply range of the package 13 as in the above-described modification, the dimensions surrounded by a rectangular frame as shown in FIG. The shape is slightly wider than the planar shape of the article to be packaged 13, and the operator can perform the supply operation while positioning the article by supplying the article to be packaged in the frame. Of course, there is no play in the width direction or the front-rear direction, and the vertical and / or horizontal length of the rectangular frame may be set so as to coincide with the dimensions of the package.

  Of course, the pattern shape of the mark described above is merely an example, and the present invention does not prevent other shapes from being adopted. Further, in each of the above-described embodiments, in the case of a T-shaped pattern, a cross-shaped pattern, or the like, either the front end position or the rear end position of the package is shown, but the present invention shows both Embodiments can also be taken. When the front and rear end positions are indicated, for example, as shown in FIG. 9, a T-shaped mark is used, the horizontal line portion a regulates the position of the package 13 in the front-rear direction, and the vertical line portion b represents the package item. By making the pattern so as to be outside of 13, it is possible to easily understand a pair of T-shaped marks that define the front and back of one package. Therefore, even in a state where the length of the article to be packaged is short and the distance between the front and rear marks is substantially equal, the supply position can be reliably understood and supplied.

  Further, as shown in FIG. 9 (a), the length between the horizontal line portions a of the front and rear marks to be paired is the same as the length of the article 13 and the front and rear as shown in FIG. 9 (b). Any aspect in the case where the length between the horizontal line portions a is longer than the length of the article 13 to be packaged can be adopted. In the case of FIG.9 (b), the to-be-packaged goods 13 will be supplied so that it may be settled in the space between the front and back horizontal line part a.

  Furthermore, although not shown in the drawing, for example, a mark having a cross shape or other pattern shape on a straight line can be arranged before and after the supply position of the package, and in that case, in particular, the length of the package As described with reference to FIG. 1, the paired marks are difficult to understand and the supply position of the package cannot be easily understood. It becomes possible to easily understand by changing the drawing mode before and after. That is, for example, by changing the size of the mark arranged on the front side and the mark arranged on the rear side, the thickness and color of the line, etc., it can be easily understood visually.

  As described above, the mark of the present invention indicates the supply position of the article 13 to be packaged, but is not necessarily limited to the front end position and / or the rear end position, and indicates the allowable range of the front end position / rear end position. Anything is enough.

  In order to improve the visibility of the laser, the display shape is preferably small. Accordingly, in the illustrated example, the T-shape of the first mark M1 and the second mark M2 is most preferable, and in the following order, the cross of the third mark M3 → the straight line of the fourth mark M4 → the frame of the fifth mark M5. . Of course, a short straight line pattern consisting only of the horizontal line part or the vertical line part shown as the T-shaped modification improves the laser visibility most. On the other hand, the visibility of the laser decreases, but the display may be a square frame (fifth mark M5) so that the mountable range can be easily determined.

  Moreover, the packaging machine to which the present invention is applied is not limited to the one shown in FIGS. 2 and 3 and can be applied to various packaging machines. As an example, for example, as shown in FIGS. 10 and 11, the present invention can be applied to a type of packaging machine that supplies an article to be packaged 13 directly onto a conveyed belt-like film 15.

  This packaging machine arrange | positions the film conveyance apparatus 41 in the upstream of the packaging machine main body 11, conveys the strip | belt-shaped film 15 drawn | fed out from the original fabric roll 16 in the horizontal direction with the film conveyance apparatus 41, The middle of the conveyance The article to be packaged 13 is supplied onto the belt-like film 15 at a predetermined position. The film conveying device 41 is composed of an adsorption belt conveyor, and conveys the belt-like film 15 while being sucked and held on the surface of the endless belt by suction means, and a conventionally known one can be used.
