Description

The present invention relates to a stick-type packaging bag filling and packaging machine for manufacturing.

  A stick-type packaging bag is generally manufactured as follows using a vertical multi-row filling and packaging machine. The original packaging film is cut into slits by a predetermined width, and each of the cut packaging films is formed into a cylindrical shape by overlapping the both side edges in a palm shape at the center in the width direction by a former, and then vertically A vertical seal is applied by a sealing device to form a cylindrical body, a horizontal seal is applied to a predetermined position of the cylindrical body by a horizontal sealing device, and then the contents are filled to form a semi-packaging bag. A stick-type packaging bag is formed by feeding out the bag one cycle at a time and further performing horizontal sealing, and the horizontal sealing portion is cut with a cutter device to manufacture a single packaging bag. At the same time, a cut line is formed in the lateral seal portion on one end side of the packaging bag.

In the stick-type packaging bag manufactured by the above means, the overlapped portion with the vertical seal is in the form of sleeping at the center in the width direction of the packaging bag. If care is not taken to hold the part, it may break along the overlapped part.
On the other hand, it has been found that when the overlapping portion is brought to a position near the end in the width direction and the cutoff line is inserted over the overlapping portion (especially on the bottom side), it can be cut smoothly.

  Therefore, conventionally, it is known to use the former described in Patent Document 1 in order to form a stick-type packaging bag having an overlapped portion at the end in the width direction. This former simply accepts the packaging film that has been fed downwards facing the front, and forms a twisted cylindrical shape so that both side edges overlap at a position close to one side in the width direction. It is a structure with a guide attached as much as possible.

JP 2004-136773 A

However, in the above-mentioned conventional one, it is difficult to obtain a curve of the guide for forming a predetermined twisted cylinder, and it is troublesome to manufacture the guide itself, resulting in high cost. For that reason, there is a problem that the accuracy of the formation position of the overlapping part is hard to come out, it can not be formed so that the cut line accurately extends over the overlapping part, the pattern on the surface side is slightly shifted for each product, Further improvements were eagerly desired.
The present invention has been completed based on the above circumstances, and has a simple structure for manufacturing a stick-type packaging bag in which the overlapping portion is moved closer to the end in the width direction. The overlap portion can be formed at an accurate position.

  In the present invention, the packaging film is sent downward by the deflecting device in a posture in which the back surface is swung to the left or right from the front, and is introduced into the former device. When viewed from the center in the width direction, both side edges are overlapped and turned into a cylindrical shape, and then a vertical seal is applied to the overlapping portion to form a cylindrical body. A stick-type packaging bag is formed by applying a horizontal seal from the front while filling the cylindrical body with contents. That is, the overlapped portion formed in the cylindrical body is at a position close to one side in the width direction when viewed from the front, and a lateral seal is applied from the front to such a cylindrical body. Then, the stick-type packaging bag in which the overlapping portion comes to a position near the end in the width direction is manufactured.

  The device to be added is only a deflecting device that changes the direction of the package film that has been fed to the front side while turning the front and back and then bends and feeds it downward, so that the structure can be kept simple. In the former device, the overlapping portions can be formed with high positional accuracy from the front in the form because the both sides are overlapped at the central portion in the width direction without turning the wrapping film and are simply curved in a cylindrical shape. As a result of the horizontal sealing, the overlapping portion that comes closer to the end also has high positional accuracy.

The manufacturing apparatus may have the following configuration.
(1) The deflection device includes a deflection bar having an oblique posture intersecting the center line of the feeding path before the feeding path, and a turning roller disposed on the front side of the deflection bar. The packaging film fed through the feeding path is turned to the front side in a reversed manner by being hung on the deflection bar, and then hung on a turning roller. The wrapping film is fed downward in a posture in which the back surface of the packaging film is swung from the front to the left or right.

(2) The deflection bar of the deflection device is provided such that the angle formed with respect to the center line of the feeding path can be changed.
By changing the angle of the deflection bar, the deflection angle from the front of the packaging film is changed, and as a result, the position of the overlapping portion in the width direction is changed. By changing the arrangement angle of the deflection bar, it is possible to cope with the position change in the width direction of the overlapping portion.

  According to the present invention, when manufacturing a stick-type packaging bag in a form in which the overlapping portion is moved closer to the end in the width direction, the overlapping portion can be formed at an accurate position with a simple structure. .

It is formed at a position close to the right edge in the width direction as viewed, and a closing portion 13 is formed by cutting the lateral seal portion 14 at both upper and lower ends. While the overlapping portion 11 is in the form of sleeping toward the center in the width direction, in the lower closing portion 13, the right portion is sealed to a high position, and the right side of the high-order seal portion 14H. A cutoff line 15 is formed from the center height position at the edge (corresponding to a little above the upper edge of the left lower seal portion 14L) to the bottom 12 of the overlapping portion 11.

  The outline of the filling and packaging machine will be described. A film roll (not shown) provided on the back side of the main body frame 30 has a film roll in which a raw fabric packaging film is wound with the surface (printing surface) outside. After the loaded and unwound original packaging film is cut at the center in the width direction, each cut half-width film Fh (see FIG. 4) is distributed to the left and right at predetermined intervals, and the half-width film Fh is further slittered. After being cut into six wrapping films F by the apparatus, the film is conveyed toward the upper end of the main body frame 30.

As shown in FIG. 1, two sets of left and right packaging bag forming mechanism portions 31 are set on the front surface of the main body frame 30 with a predetermined interval (in the same figure, only the right packaging bag forming mechanism portion 31 is provided. (Illustrated).

  The deflection bar 36 is obliquely intersecting the center line Fo1 of the packaging film F, in other words, the center line 34o of the feeding path 34 with a predetermined inclination angle α on substantially the same horizontal plane as the feeding path 34 described above. Arranged in posture. More specifically, the deflection bar 36 is attached along one side edge of the elongated attachment plate 37, and the shaft 38 suspended from the proximal end side of the attachment plate 37 is positioned below the feeding path 34. On the other hand, a screw rod 41A is erected on the upper end of a support column 41 standing on the front end side of the mounting plate 37, while being rotatably supported by a bearing portion 39A of a support frame 39 arranged facing left and right. The threaded rod 41A protrudes upward through an arc-shaped slot 42A formed in the mounting frame 42 disposed above the feeding path 34, and a nut 43 is screwed into the projecting end and tightened. It is fixed.

In other words, the swinging posture of the mounting plate 37 can be adjusted while swinging about the shaft 38, and accordingly, the center line Fo1 of the packaging film F in the deflection bar 36 (the center line of the feeding path 34). 34o) and the inclination angle α can be set. In this embodiment, the inclination angle α is set to “25 degrees”, for example.
When the packaging film F is fed to the front side with the posture with the front face Fa facing upward, and is wrapped around the deflection bar 36 from the upper surface to the lower surface side, the packaging film F is reversed. After the back surface Fb is directed upward, the sheet is deflected so as to be fed toward the right front side. The angle formed by the center line Fo1 of the packaging film F before deflection and the center line Fo2 of the packaging film F after change, that is, the deflection angle β of the deflected packaging film F is twice the inclination angle α of the deflection bar 36. “50 degrees”.

A turning roller 45 is disposed at a front position in the feeding direction of the packaging film F after deflection. The turning roller 45 is composed of three upper and lower portions serving also as tension rollers. Each of the turning rollers 45 takes a horizontal posture perpendicular to the center line Fo2 of the deflected packaging film F, and is a mounting plate for the deflection bar 36. 37 are arranged side by side at equal intervals from a slightly lower position of 37. Each turning roller 45 is passed between a pair of support pillars 47 suspended or erected from the upper and lower support plates 46 (see FIG. 1) and is supported rotatably.
The deflected wrapping film F is sent downwardly in a posture in which the back surface Fb is directed obliquely toward the front side while being alternately hung on the front and back sides in order from the top with respect to each turning roller 45. .

The former device 50 is for introducing the packaging film F sent downward and forming a cylindrical shape, and also serves as a supply pipe for the contents A as shown in FIGS. The former pipe 51 has a structure in which a predetermined clearance is fitted in a cylindrical seal portion 56 in a vertical seal device 55 described later. An opening groove 57 is cut along the vertical direction on the outer surface of the cylindrical seal portion 56 on the right front side as viewed from the front.
As will be described in detail later, the wrapping film F is wound around the outer periphery of the former pipe 51 in a cylindrical shape while being introduced into the cylindrical seal portion 56, and both side edges are overlapped in the center in the width direction. The palm portion protrudes from the left edge of the opening groove 57. A receiving surface 58 is formed on the left edge of the opening groove 57 to receive the jointed portion.

As shown in FIGS. 4 and 5, the vertical seal device 55 includes the cylindrical seal portion 56 described above and a vertical seal block 60 that is driven forward and backward toward the receiving surface 58 of the cylindrical seal portion 56. ing. The cylindrical seal portion 56 is attached side by side in front of the fixed side vertical seal portion 62. A movable-side vertical seal portion 63 is provided on the front side of the fixed-side vertical seal portion 62 so as to be openable and closable. It is mounted so that it can move forward and backward.
In the vertical sealing device 55, in the former device 50 described above, each packaging film F is bent into a cylindrical shape, and both side edges are overlapped with each other to form the overlapping portion 11, and shown in FIG. As described above, the vertical seal block 60 heated to an appropriate temperature advances and presses the overlapping portion 11 against the receiving surface 58, whereby the vertical seal is applied, whereby the cylindrical body T is formed. Yes.

  As shown in FIG. 7, the lateral seal device 65 has a structure in which lateral seal blocks 67 </ b> A and 67 </ b> B that make a pair in the front and rear are provided in a base frame 66 so as to be able to contact and separate. Seal forming portions 68A and 68B are formed on the opposing surfaces of both lateral seal blocks 67A and 67B. At the left and right ends of the base frame 66, two longitudinal slide shafts 69 are provided penetrating the front and rear, and the horizontal seal device 65 has a predetermined stroke (as a product) along the slide shaft 69. It is possible to move up and down by the length of one bag in the packaging bag 10.

In the horizontal seal device 65, when the horizontal seal device 65 is at the upper end position of the stroke, both the horizontal seal blocks 67A and 67B are moved so as to be attracted to each other, and the vertical seal is applied as described above. A horizontal seal is applied by clamping a predetermined position of the cylindrical body T with seal forming portions 68A and 68B heated to an appropriate temperature.
Further, when the horizontal seal device 65 is lowered to the lower end position of the stroke in a state where the horizontal seal is applied as described above, the cylindrical body T is pulled downward by one bag of the packaging bag 10, and thereafter both The horizontal seal blocks 67A and 67B are separated from each other and returned to the upper end position, and the above-described operation is repeatedly executed. Therefore, the horizontal sealing device 65 also serves as the feeding device 70 of the present invention.

  As shown in FIGS. 2 and 4, the filling device 75 has a supply port 51A protruding from the upper end of the former pipe 51 constituting a part of the former device 50 so as to extend upward to the right front. The connection chute 76 is connected to the upper end. In the connection chute 76, the contents A stored in a hopper (not shown) are weighed and charged.

Although the cutter device 80 is not shown in detail, the fixed blade and the movable blade are arranged to face the back side and the near side across the downward feeding path of the cylindrical body T, and the movable blade becomes the fixed blade. It is comprised by being provided so that contact / separation is possible.
In the cutter device 80, the movable blade advances and is pressed against the fixed blade, so that the lateral seal portion 14 of the packaging bag 10 filled with the contents A is cut and functions to obtain individual packaging bags 10. In addition, the above-described tear line 15 is formed at a predetermined position of the one closing portion 13 of the packaging bag 10.

  As shown in FIG. 1, a guide body 82 is provided at a position above the cutter device 80 for inserting the packaging bags 10 in each row and correcting the posture before being introduced into the cutter device 80. Also, at the lower position of the cutter device 80, a discharge chute 84 is provided corresponding to each row for receiving the individual packaging bags 10 cut individually in each row and discharging them on a conveyor (not shown). ing.

This embodiment has the structure as described above, and its operation will be described again.
As shown in FIG. 1, the six packaging films F cut by the slitter device are turned around by the turning roller 33 so that the front surface Fa is aligned in a horizontal posture facing upward and fed toward the front side. And is guided to a deflecting device 35 disposed on the front side of the feeding path 34.
In the deflecting device 35, as shown in FIG. 3, the packaging film F fed to the front side with the feeding path 34 with the surface Fa facing upward is hung from the upper surface to the lower surface side with respect to the deflection bar 36. By being turned, the packaging film F is turned upside down, and is deflected and fed to the right front side. As shown in FIG. 2, the wrapping film F after being deflected is directed downward in a posture in which the back surface Fb is swung to the right front side (swing angle β: 50 degrees) while being hung on the three turning rollers 45. Sent out.

  Subsequently, the packaging film F is guided to the former device 50. In the former device 50, as shown in FIG. 6, when viewed from the direction in which the packaging film F is swung, both side edges are formed in the shape of a palm. In the vertical seal device 55, the heated vertical seal block 60 is pressed against the receiving surface 58 by the heated vertical seal block 60 after the overlapped portion 11 is formed. The cylindrical body T is formed. Here, the overlapping portion 11 is tilted forward in the clockwise direction when viewed from above.

Next, a horizontal seal is applied to a predetermined position of the cylindrical body T by the horizontal seal device 65 at the upper end position of the stroke. Specifically, as shown in FIG. 8, the cylindrical body T is configured such that the position of the overlapping portion 11 is swung to the right and forward, and the overlapping portion 11 itself falls forward in the clockwise direction when viewed from above. In this case, it is located between the front and rear horizontal seal blocks 67A and 67B. However, when viewed from the front, the overlapping portion 11 is located at the right edge in the width direction, and the overlapping portion 11 itself is The shape is tilted to the left.
Since the cylindrical body T having such a posture is sandwiched between both horizontal seal blocks 67A and 67B as shown by arrows in FIG. As shown in FIG. 9, the overlapping portion 11 is formed at a position close to the right side edge in the width direction, and the overlapping portion 11 itself is formed in a shape lying on the center side in the width direction. .

As described above, when the horizontal seal portion 14 is formed at a predetermined position of the cylindrical body T, the content A stored in the hopper is filled by a predetermined amount via the filling device 75 to form a semi-packaging bag, The semi-wrapping bag is pulled one bag at a time as the lateral seal device 65 is lowered, and then the lateral seal is applied by the lateral seal device 65 raised to the original position, whereby both ends are closed. A bag 10 is formed. After that, the horizontal seal portion 14 is cut in the cutter device 80 and the cut line 15 is also inserted, whereby the packaging bags 10 shown in FIGS. 10 and 11 are manufactured one by one, and the discharge chute 84 is slid down to the next. Transferred to a conveyor or the like for the process.
In the packaging bag 10 formed in such a shape, the overlapping portion 11 to which the vertical seal is applied is at a position close to the end in the width direction, and the tear line 15 becomes the bottom 12 of the overlapping portion 11. Since it is the shape put over the side, when it cuts from the cut line 15, it can cut off smoothly.

As described above, in the present embodiment, when manufacturing the stick-type packaging bag 10 in which the overlapping portion 11 to which the vertical seal is applied has come to a position near the end in the width direction, the packaging film F is formed by the deflecting device 35. The back surface Fb is sent to the former device 50 in a posture oriented in the direction swung from the front to the right side. In the former device 50, both side edges are overlapped at the center in the width direction when viewed from the swung direction. The cylindrical body T is formed by applying a vertical seal to the overlapping portion 11 by the vertical sealing device 55 after being bent into a shape, and the horizontal sealing device 65 is filled with the content A in the cylindrical body T. Thus, means for applying a horizontal seal from the front is adopted.
In short, when viewed from the initially swung direction, a cylindrical body T having a posture in which the overlapping portion 11 comes to the center in the width direction is formed, and this cylindrical body T is viewed from the front. Since the overlapping portion 11 is at a position close to the right side edge in the width direction, by applying a horizontal seal from the front to the cylindrical body T, as a result, the overlapping portion 11 is closer to the right side edge in the width direction. The stick type packaging bag 10 which has come to the position is manufactured.

  The only device to be added in the above is the deflecting device 35 that turns the fed packaging film F upside down and changes the direction to the obliquely front side, then bends it downward and sends it out. In the former device 50, the wrapping portion F can be formed with high positional accuracy since the wrapping film F is simply bent in a cylindrical shape by superimposing both side edges at the central portion in the width direction. As a result of the horizontal sealing, the overlapping portion 11 that comes closer to the end can also have high positional accuracy. Therefore, it is possible to form the cutoff line 15 so as to extend accurately over the overlapping portion 11 and to prevent the pattern on the surface side from being shifted.

  In the deflection device 35, by changing the inclination accuracy α of the deflection bar 36, the deflection angle β from the front of the packaging film F after deflection is changed, and as a result, the position of the overlapping portion 11 in the width direction can be changed. it can. In this case, it is necessary to change the direction of the turning roller 45, the former pipe 51 and the like in accordance with the inclination accuracy α of the deflection bar 36. In addition, when the receiving surface 58 provided on the cylindrical seal portion 56 is provided on the right edge of the opening groove 57 and a vertical seal is applied to the palm portion on the receiving surface 58, the overlapping portion 11 is placed on the right side in the width direction. It is possible to form a posture lying on the edge side.

The packaging bag 10A according to the second embodiment has an overlapping portion 11A that is overlapped in a palm shape and has a vertical seal formed at a position close to the left side edge in the width direction when viewed from the back side. The part 11A is formed in a shape lying on the left side edge in the width direction, and a cut line 15A is formed from the left side edge to the tip part 17 of the overlapping part 11A in the lower closing part 13A.

When manufacturing such a packaging bag 10A, the deflection bar 36 in the deflection device 35 is arranged in an oblique posture that is symmetrical to the first embodiment, and the feeding path 34 is fed to the front side. This can be dealt with by feeding the wrapped packaging film F with the front and back being reversed and deflected to the front side obliquely to the left.
By changing the inclination accuracy of the deflection bar 36, the position of the overlapping portion 11A in the width direction can be changed, and by selecting the position of the receiving surface 58 provided on the cylindrical seal portion 56 to the left or right of the opening groove 57, The ability to select the direction in which the overlapping unit 11A lies is the same as in the first embodiment.
