Description

  The present invention relates to a horizontal pillow wrapping machine, for example, a technique for suppressing a part of a package to be missing, such as noodle residue in dry noodles, and sealing other foreign matters as they are. About.

  The horizontal pillow packaging machine has the following configuration. First, the strip-shaped film wound up by the raw fabric roll is continuously supplied to the bag making device, and when the bag making device is passed, the tubular film formed into a tubular 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.

  As a result, when the article to be packaged passes through the bag making machine, it is stored in the cylindrical film at predetermined intervals, and the article to be packaged is conveyed in the horizontal direction 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 includes a top sealer disposed with a tubular film interposed therebetween, and the top sealer sandwiches the tubular film in the lateral direction of travel (the portion where the front and rear packages are not present) and heats it.・ Pressurize to heat seal and cut the end seal with the built-in cutter. Thereby, the part of the cylindrical film in which the article to be packaged at the tip is stored is separated from the subsequent cylindrical film, and the package is manufactured.

  In such a horizontal pillow packaging machine, there is a problem of biting of an object to be packaged in an end seal device. That is, the timing of supplying the packaged object to the tubular film is shifted, or the packaged object moves relative to the tubular film while the packaged object is being transported together with the tubular film. It may be located at the sealing part of the tubular film in the apparatus. Then, when the pair of top sealers sandwich the cylindrical film and perform the sealing process, a situation occurs in which the packaged object is also sandwiched together. Then, since it becomes an abnormal state, it is necessary to temporarily stop the horizontal pillow packaging machine and perform a predetermined restoration work, and there is a possibility of failure of the end seal device. The shorter the distance between the front and back of the package, the higher the probability of such a problem.

  For example, when the packaged item is dry noodles such as instant noodles, so-called small noodle residue separated from the packaged item may fall during conveyance of the packaged item, and the noodle residue is bitten with a top sealer. May cause defective products.

  With respect to the suppression of biting of small articles such as noodle residue in the end seal device, various configurations have been proposed in the past including, for example, Patent Document 1.

JP 2007-106489 A

  The noodle residue biting in the end seal device is mainly performed by placing the article to be packaged after passing through the bag making machine at a predetermined position of the cylindrical film and dropping from the article to be conveyed as the cylindrical film moves. It is caused by equal noodle residue. However, the drop of noodle residue is not limited to dry noodles in the tubular film. For example, noodle residue dropped from a packaged article (dried noodles) being conveyed by a packaged article conveyance and supply device arranged on the upstream side of the bag making machine may move to the bag making machine side. In addition, there is a possibility that noodle scraps may fall due to an impact or the like when the dried noodles being moved from the packaged article conveying and feeding apparatus to the bag making machine are transferred.

  Then, some small articles such as noodle residue move inside the bag making machine and can be transferred together with the packaged items into the cylindrical film, but some are cylindrical along the inner peripheral surface of the bag making machine. In some cases, the film is sandwiched between film overlapping portions at both side edge portions of the belt-like film to be bag-made. Furthermore, when the packaged article transport and supply device is a finger conveyor, the noodle residue may fall from the slit formed on the conveyance surface.For example, if the finger conveyor moves at a high speed, the dropped noodle residue is completely removed. There is a case where it moves obliquely downward and forward without falling under the packaged article transport and supply device. Then, the noodle residue moving toward the diagonally lower front may enter between the film overlapping portions on both side edge portions of the strip-shaped film formed in a cylindrical shape. Then, the noodle residue is directly center-sealed by the center seal device and becomes a defective product.

  Although the example of the noodle residue of dried noodles has been described, confectionery and other foods, as well as foods other than foods, have similar problems. Furthermore, the small articles are not limited to those that are separated and dropped from the packaged object, and there is a possibility that a foreign object other than the packaged object may enter for some reason.

  The present invention provides a horizontal pillow packaging machine that can prevent a small article dropped from an object to be packaged such as a so-called noodle residue and other various foreign matters from being mixed into the center seal device side with a simple configuration. For the purpose.

Formed in order to solve the above problems, the present invention is a strip film fed by continuous, a bag making device in which the both side edge portions is formed in a cylindrical shape so as to mate with the lower, to the tubular A center seal device that seals the polymerization end of the cylindrical film, and a top sealer that is disposed on the downstream side of the center seal device and that is disposed above and below the cylindrical film. A horizontal pillow wrapping machine provided with an end seal device for sealing in the width direction, which is positioned immediately before a portion where both side edge portions of the belt-like film are combined in the bag making machine, and between the side edge portions. It is premised on the provision of a biting prevention guide for preventing articles from entering .

  When small articles such as noodle residue resulting from a part of a package being dried, such as dry noodles, are generated in a band-shaped film that is formed into a cylindrical shape by a bag-making machine, both side edges of the band-shaped film When entering the portion where the two are joined and trying to advance into the bag making machine as it is, the biting prevention guide disposed immediately before the portion where the two side edge portions are joined is prevented from further advancement. Therefore, the small article does not enter between the side edge portions of the belt-like film, and can be prevented from being bitten and sealed by the center seal device at the subsequent stage. The items to be packaged are not limited to dry noodles, and include, for example, fragile items such as confectionery, and items that are decorated on the surface. In some cases, a part of the main body of the confectionery is missing, or a part or the whole of the decoration part falls and becomes a small article to be prevented or excluded from biting according to the present invention. Furthermore, it is not limited to food, and non-food is also targeted. Further, the small articles to be prevented from being bitten are not limited to those dropped from the packaged items, and may be mixed for some reason.

(1) The present invention is based on the premise described above, and the biting prevention guide has a Y-shaped flat cross section, and a Y-shaped I-shaped portion hangs downward from the bottom surface of the bag making machine. It was fixed in a state of entering between the sections, and both side edge portions of the strip film were configured to pass between the vertical section and the I section .

(3) Further, according to the present invention, based on the premise described above, the biting prevention guide includes a drop guide portion that is inclined downward along the conveyance direction, and the small article is prevented from entering by the biting prevention guide. were to be dropped is guided in its fall guide. In this way, it is possible to smoothly guide the fall of the small articles whose entry has been blocked by the biting prevention guide.
(2) Both (1) and (3) described above may be provided. (4) The biting prevention guide may be provided with a main body having a V-shaped cross section, and the main body is arranged so that the V-shaped back vertex faces downstream.

  In the present invention, since the biting prevention guide is provided immediately before the portion where the both side edge portions of the belt-like film that is formed into a cylindrical shape by the bag making machine are combined, it occurs before the both side edge portions are combined. Since the small article hits the biting dead child guide and prevents further advancement, small items that fall from the packaged item such as so-called noodle residue and other various foreign objects are caught between the edges on both sides. It can be prevented from entering the center seal device side.

  FIG. 1 shows a preferred embodiment of the present invention. The horizontal pillow packaging machine 10 according to the present embodiment includes a packaging machine body 11, a film supply device 12 that continuously supplies a belt-like packaging film to the packaging machine body 11, and an upstream side of the packaging machine body 11. A packaged article transport and supply device 14 that is arranged and supplies the packaged article 13 to the packaging machine body 11 at predetermined intervals is provided.

  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. Various rollers 17 are arranged at predetermined positions from the original fabric roll 16 to the packaging machine main body 11, and the belt-like film 15 fed out from the original fabric roll 16 is stretched over the rollers 17, thereby providing a predetermined path. It is guided to the packaging machine main body 11 through. 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.

  The package transporting and supplying device 14 includes a sprocket 17 (only the front in the traveling direction is shown in the figure) arranged at the front and rear, an endless chain 18 spanned over the plurality of sprockets 17, and a predetermined pitch on the endless chain 18. It is comprised by the several pushing finger | toe 19 attached for every. Thereby, when the pushing finger 19 hits the rear surface of the article 13 to be packaged, the article 13 also moves forward with the movement of the pushing finger 19.

  The packaging machine main body 11 includes a bag making device 20 for making the supplied belt-like film 15 into a tubular film 21, and both side edge portions of the polymerized belt-like film 15 disposed on the downstream side of the bag making device 20. A pinch roller 23 composed of a pair of rollers that pinch 15a from both sides to give a conveying force; a center seal device 24 that is arranged on the downstream side of the pinch roller 23 and seals both side edges 15a; and the center seal device 24, a conveyor belt 25 disposed downstream of the conveyor belt 24, an upper restraining belt 26 disposed above the conveyor belt 25, an end seal device 30 disposed downstream of the conveyor belt 25, and an end seal device 30 An unloading conveyor 27 is provided on the downstream side. In this embodiment, the center seal device 24 is composed of a pair of left and right heating rollers, and heat-seals the heating rollers while applying a predetermined pressure to the side edge portions 15a.

  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. Further, since the article to be packaged 13 is included in the cylindrical film 21 in this way, the belt conveyor 23 conveys the cylindrical film 21 including the article to be packaged 13.

  The upper restraining belt 26 is disposed 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, by passing through the end seal device 30, the leading portion of the tubular film 21 is separated from the subsequent portion, and the package 28 is manufactured.

  The end seal device 30 includes a pair of top sealers 31 and 32 that are vertically opposed to each other with the tubular film 21 interposed therebetween, and maintains a state in which the seal surfaces 31a and 32a of the top sealers 31 and 32 are opposed to each other. Each revolves around a predetermined trajectory. As a mechanism for revolving the top sealers 31 and 32 along a predetermined locus, a known mechanism called a box motion can be used. This box motion moves forward at the same speed as the tubular film 21 when the top sealers 31 and 32 mesh with each other and sandwich the tubular film 21, and then the top sealers 31 and 32 move from the tubular film 21. When it is separated, it repeats moving backward along a predetermined trajectory. As a result, the tubular film 12 can be sandwiched between the top sealers 31 and 32 and maintained in a pressurized and heated state for a certain period of time, so that it can be reliably heat-sealed and the tubular film can be moved continuously. Of course, when the tubular film is moved intermittently, the top sealers 31 and 32 are only moved up and down, and when the tubular film is temporarily stopped, the top sealers 31 and 32 are moved up and down once and the sealer It can also be cut. In addition, the carry-out conveyor 27, the transfer conveyor 25, and the like may move the front end on the end seal device 30 side in the front-rear direction in accordance with the forward and backward movement of the top sealers 31 and 32. For this technique, for example, a mechanism disclosed in Japanese Patent Laid-Open No. 9-286413 can be used. The end seal device 30 is not limited to the box motion as in this embodiment, and may be a rotary type.

  As shown in FIG. 2 and subsequent figures, the bag making machine 20 includes a left guide plate 41 and a right guide plate 42. The left guide plate 41 includes a bottom portion 41a, a left wall 41b rising from the left end of the bottom portion 41a, and a vertical portion 41c depending from the right end of the bottom portion 41a. The right guide plate 42 includes a bottom portion 42a, a right side wall 42b rising from the right end of the bottom portion 42a, and a vertical portion 42c depending from the left end of the bottom portion 42a. The left guide plate 41 and the right guide plate 42 have bottom portions 41a and 42a positioned on the same plane, and vertical portions 41c and 42c are arranged to face each other in a close state. The left guide plate 41 and the right guide plate 42 are connected and integrated by a connecting plate 43 at an upstream upper portion of the left side wall 41b and the right side wall 42b. Further, the bottom 41a of the left guide plate 41 is an inclined side 41a 'that gradually protrudes outward as the right end on the upstream side (carrying side) goes downstream (conveying direction), and the bottom portion 42b of the right guide plate 42 is The left end on the upstream side (carrying-in side) becomes an inclined side 42a ′ that gradually protrudes outward as it goes downstream (conveying direction). As a result, the distance between the two slopes 41a ′ and 42a ′ is the widest at the upstream end and approaches as it goes downstream. Vertical portions 41c and 42c are respectively formed at linear side ends following the inclined sides 41a 'and 42a'. Moreover, the upstream edge of the vertical parts 41c and 42c is inclined downward. That is, the upstream end edge has a shape that is positioned on the downstream side as it goes downward.

  When the belt-like film 1 is supplied into the bag-making device 20 from the upper obliquely upper side to the bag-making device 20 having such a configuration, the belt-like film 1 is tubular along the inner peripheral surfaces of both guide plates 41 and 42. Formed. Then, both sides in the width direction orthogonal to the transport direction of the belt-like film 1 are guided by the inclined sides 41a ′ and 42a ′ and guided to the lower center of the bag making machine 20, and finally the side edges are joined. In the state, it reaches the gap between the vertical parts 41c and 42c and is conveyed as it is. And it is center-sealed with the center-seal apparatus arrange | positioned in the downstream of the bag making machine 20 with the state which the both side edge part overlapped. The configuration of the bag making machine 20 is the same as that of the conventional one.

  And in this embodiment, the biting prevention guide 50 was arrange | positioned just before the part which the both-sides edge part of the strip | belt-shaped film in the bag making machine 20 joins. The biting prevention guide 50 has a substantially Y-shaped plane, and a main body 50a formed of a Y-shaped V portion is disposed so as to protrude upstream from the vertical portions 41c and 42c. The connecting portion 50b composed of the above portion is sandwiched between the vertical portions 41c and 42c and fixed using bolts 55 and nuts 56.

  As shown in FIG. 5, a predetermined gap is formed between the connecting portion 50b and the vertical portions 41c and 42c. This gap is wider than the film thickness of the strip-shaped film 1, and the left and right side edge portions of the strip-shaped film 1 pass through the gap formed between the connecting portion 50b and the vertical portions 41c and 42c, respectively. And since the V-shaped main body 50a is arranged in front of the upstream edge of the vertical portions 41c and 42c, it covers the upstream opening of the gap portion between the vertical portions 41c and 42c. The small article hits the main body 50a of the biting prevention guide 50 and is further prevented from moving forward (entering into the vertical portions 41c and 42c) and falls. Therefore, it is possible to suppress the occurrence of an abnormal situation in which small articles such as noodle residue and powder are sandwiched between the edge portions on both sides of the belt-like film 1.

  In addition, since the back of the main body 50a is inclined downward, and the drop guide is such that its position is lowered as it goes forward in the traveling direction, the small article is guided along the downwardly inclined drop guide, and more reliably. It can be dropped and eliminated downward.

  The biting prevention guide 50 according to this embodiment includes two first and second belt plate members 51 and 52. The first and second strip members 51 and 52 are both formed by bending a stainless steel flat plate. That is, as shown in FIG. 6, it is bent along a parallel line L along one oblique side of the one-side trapezoidal flat plate so that a parallelogram portion between the line L and the oblique side opens outward by a predetermined angle. . The parallelogram portion constitutes the main body 50a. In addition, elongated through holes 51a and 52a are formed at predetermined positions of the first and second strip members 51 and 52 along the transport direction. The through holes 51a and 52a are holes for inserting the bolts 55. By making the through holes long, the position in the transport direction can be adjusted when the biting prevention guide 50 is attached.

  Further, when the first and second strip members 51 and 52 are fixed using the bolt 55 and the nut 56, a washer 58 is disposed between the strip members 51 and 52 and the vertical portions 41c and 42c. Yes. By providing this washer 58, at least a gap corresponding to the thickness of the washer 58 is ensured between the two band plate members 51, 52 and the vertical portions 41c, 42c, so that the band-shaped film 1 can pass through the gap. Further, since the fastening force by the bolt 55 and the nut 56 is transmitted to both the band plate members 51 and 52 via the washer 58, the both band plate members 51 and 52 are also in close contact with each other, and no gap is generated on the contact surface. Noodle residue or the like does not enter between the two band plate members 51 and 52.

  In the present embodiment, the two strip plate members 51 and 52 are brought into contact with each other and fixed by fastening with bolts and nuts. However, the two strip plate members 51 and 52 may be integrated in advance by welding or other means.

  In the various embodiments and modifications described above, since the first and second belt plate members 51 and 52 are overlapped, a groove is formed in the back of the V-shaped main body 50a. Therefore, there is a possibility that small articles such as noodle residue remain in the groove. Even in such a case, since it does not enter the bag making machine 20, the generation of defective products can be prevented, but the cleaning process for removing small articles that have entered the narrow gap becomes complicated.

  Therefore, for example, as shown in FIG. 7, a V-shaped protective member 59 bent at the back is attached to the open opposing surfaces of the first and second belt plate members 51 and 52. In this way, since there is no gap in the back of the V-shaped main body 50a, it does not enter through the gap between the two band plate members 51 and 52, and it becomes more hygienic and easy to clean. As the protective member 59, for example, a member having an adhesive member applied to the back surface such as a seal member can be used because it can be easily bonded to the two band plate members 51 and 52. Of course, the protective member 59 is not limited to the one to which the adhesive is applied like the seal member, and may be a plate material made of stainless steel or other materials bent into a V shape, or other various materials. Can be used practically.

  Further, the biting prevention guide according to the present invention is not limited to a structure in which the main body 50a is configured by combining a plurality of members, such as using the first and second belt plate members 51 and 52 appropriately bent. For example, a V-shaped plate member and a flat plate constituting the main body may be prepared, a flat plate may be welded to the tip of the V-shaped plate member, and the biting prevention guide may be fixed by the flat plate. Moreover, you may make it provide the connection part extended from the back | inner side of the V-shaped main body and the main body by bend | folding one flat plate suitably.

  Further, in the various embodiments and modifications described above, the connecting portion is arranged so as to be sandwiched between the vertical portions of the bag making device 20, but the present invention is not limited to this and is connected to a place other than the vertical portion. Is of course good.

In the various embodiments and modifications described above, the shape of the main body 50a is V-shaped, but the present invention is not limited to this. For example, the position on the upstream side may be shifted back and forth, and other various shapes such as a triangle may be taken even if it is not V-shaped.
Various other shapes are possible.
