Description

  The present invention relates to a bag making and filling and packaging apparatus for continuously manufacturing a bag package by filling a product inside while forming a square bottom packaging bag such as a gusset bag.

Products with relatively large individual sizes, such as Japanese confectionery and Western confectionery, are often distributed or sold individually in a packaged state. Conventionally, as a packaging device for packaging products in units of one or several pieces in a square bottom bag such as a gusset bag, an opening of a separately formed square bottom bag is opened and supplied to a filling position, and the filling position is reached. There has been known an individual packaging device that puts a product into each square bottom bag, closes the opening of the bag, and packages the product (see Patent Document 1). This type of packaging device conveys and supplies individual square-bottom bags intermittently in the horizontal direction by a conveyor, opens the square-bottom bags in the middle of conveyance, and individually puts products into the opened square-bottom bags, The product can be continuously packaged by repeating the process of closing the opening of the square-bottom bag that has been put into the product.
Japanese Examined Patent Publication No. 44-5592 (FIGS. 1 and 2)

  However, the above individual packaging device is excellent in that individual products such as Japanese confectionery and Western confectionery can be automatically packaged without relying on complicated manual packaging work. Because it is used, packaging costs are higher compared to filling bags and closing bag openings using bags produced continuously from web-like packaging materials, such as bag-filling and packaging machines. It is. Also, depending on the quality of the packaging material used as the material of the bag, the operational stability of the packaging device changes, and a good packaging state is not always obtained. Furthermore, since the individual packaging apparatus is a type of apparatus that fills a product into a square bottom bag that is manufactured in advance and is conveyed by a conveyor, the conveyor alone tends to occupy a wide space in the workplace. In addition, since complicated mechanisms are arranged at each station as mechanisms for holding, opening and closing the bag, the price of the apparatus is also increased.

  On the other hand, a cylindrical packaging film is formed from a flat packaging film, a product is introduced while forming a packaging bag from the cylindrical packaging film, and a bag package containing the product is continuously formed by applying a seal in the transverse direction. 2. Description of the Related Art A vertical bag making and filling packaging machine is known as a packaging machine that is manufactured in an automated manner. It has also been devised to continuously manufacture square-bottom bags containing individual products by applying this type of packaging machine to the production of square-bottom bags and filling the square-bottom bags with products. This vertical bag making and filling device is a product in which a cylindrical packaging film is once formed from a flat packaging film, and then the cylindrical packaging film is gradually changed from a cylindrical shape to a square cross section. A square bottom bag is formed by forming a cylindrical packaging film with a square cross section by guiding it to the outer peripheral surface of the cylindrical guide, and folding the gusset from the side of the bag when end sealing the cylindrical packaging film with a square cross section. Is forming. An individual product is put into the square bottom bag and the opening of the square bottom bag is closed, whereby the individual product is packaged by the square bottom bag.

As an example of the above-mentioned type of packaging device, the body is a square cylinder with a square cross section, the lower base is a flat bottom, the upper base is squeezed and sealed in a single-flow inclined manner, and the edge is heat sealed or bonded Filled with a predetermined weight or volume of a product such as a snack, a light and bulky snack confectionery, a bulky product such as a seasoning, a liquid such as a powdered granule, a juice, a viscous material, etc. A rectangular tube packaging bag manufacturing apparatus that can perform boxing in a case with a high filling rate has been proposed (see Patent Document 2). In this bag-filling and packaging apparatus, a film-like packaging sheet is formed into a square tube by a double-cylinder cylinder integrally extending from the former. The cylinder is cylindrical from the upper part to the middle part. The cylinder is formed into a rectangular cylinder that can be slid relative to the inside and outside, with the cross-sectional shape gradually and smoothly changing from a middle part to the lower part. Therefore, after the packaging sheet is formed into a cylindrical shape by the former, the cross-sectional shape is gradually deformed into a rectangular tube shape by the cylinder.
JP-A-7-285511 (paragraph [0025], FIG. 1, FIG. 3 and FIG. 4)

Further, as another example of bag-filling and packaging, the present applicant shall tightly seal the inner surface of the web that is folded into a triangle forming a square bed portion between the end sealer and the square bed forming gusset claw. Thus, there is provided a vertical bag making and filling method that can eliminate the entry of an article to be wrapped into the triangular folded portion of the square floor portion, can lay the bottom seal rib sideways, and can form a smooth square bed bag. (See Patent Document 3). Also in this vertical bag making and filling method, a continuous web is bent by a former and folded up into a shape that wraps a product dropping cylinder of a cross-sectional cylinder passed through the inside of the former, and both edges of the web that meet the front side of the product dropping cylinder are Vertically sealed and formed into a packaging cylinder. The lower part of the product dropping cylinder is composed of a deformed cylinder and a rectangular cylinder whose horizontal cross section changes from a circle to a rectangle, and the wrapping cylinder having a circular cross section is changed to a rectangle to facilitate gusset molding.
JP-A-10-59308 (paragraph [0006], FIG. 1)

  In the above bag-filling packaging method and apparatus, in any case, a flat web-shaped packaging material is once formed into a cylindrical packaging film having a circular section, and then continuously deformed to form a cylindrical packaging film having a rectangular section. Have gained. FIG. 4 is a perspective view schematically showing a conventional tube-making guide and a cylindrical packaging material that is travel-guided thereby. As shown in FIG. 4, the tube-making guide 60 is placed on the upper side, has a length L1, and has a circular cross section. It has a rectangular tube guide portion 63 having a rectangular section and having a placed length L3. The flat web-shaped packaging material is formed into a cylindrical packaging film 65 having a circular cross section in the cylindrical guide portion 61 and is travel-guided, and the cylindrical packaging is continuously deformed from a circular cross section to a rectangular cross section in the sectional shape transition portion 62. It becomes a film 66 and travels and is guided in a state of a cylindrical packaging film 67 having a rectangular cross section in the rectangular tube guide portion 63. Therefore, the tube-making guide 60 must be longer in the longitudinal direction by at least the length of the cross-sectional shape transition portion 62 than the tube-making guide that fills the bag with the tubular packaging film 65 having a circular cross-section. I don't get it. As a result, there is a problem that the height of the bag filling and packaging apparatus is increased, the apparatus is enlarged, a large installation space is required, or the price of the apparatus is increased.

  Further, in the bag making filling and packaging method and apparatus described above, when the product to be packaged is a rose product such as snack confectionery or a granular material, a predetermined amount of the product retained and measured in the hopper is filled. Even when dropped into the product, the product is packaged with almost no problem of breakage. However, Japanese confectionery such as buns and Western confectionery such as cupcakes generally have a vertical orientation, and the product value may be reduced if they are not placed correctly in the bag. In addition, the above products are generally fragile, and when they are put into a simple filling cylinder, there is a possibility that the shape may be lost due to an impact when landing on the bottom of the bag, and there is a possibility that the commercial value is lowered. For such product filling, if the product can be thrown in close to the square bottom of the square bottom bag, the impact received by the product can be reduced, but when using a long filling cylinder, the position approaching the square bottom It is difficult to design the supply means for supplying the product. However, for bags manufactured in bag-filling packaging, it is preferable that the amount of packaging material used be small, so the diameter of the filling cylinder is usually set to a size that allows the product to be introduced. . Although it is conceivable that the supply means is constituted by a pair of long open / close arms that grip both sides of the product or support the bottom, it is possible to open and close the pair of long open / close arms within a long and narrow cross-section. Since it is generally difficult, it is practically impossible to package such a product using a bag making and filling method and apparatus.

  Therefore, in a bag making and filling and packaging apparatus for filling and packaging products while producing a square bottom bag, by using a supply means that can extend in the filling direction without taking up space in the filling cylinder, There is a problem to be solved in that the product is loaded and unloaded as close to the square bottom as possible, and the impact that the product receives from the square bottom of the bag when the product is loaded is reduced.

  The object of the present invention is to avoid the deformation and damage of the product caused by the product colliding with the square bottom of the bag when filling the product, by loading and unloading the product with the square bottom bag as close as possible to the square bottom. Then, while preventing the fall of the commercial value as a package body, it is providing the bag making filling packaging apparatus which can achieve size reduction of an apparatus.

  In order to solve the above-described problems, a bag-filling / packaging apparatus according to the present invention can be filled with a product inside and can be moved up and down in the filling cylinder so that a cylindrical packaging material can be guided on the outside. And a metal tape provided with a product receiver capable of supporting the product at the tip, and a tape that extends into the filling cylinder and guides the metal tape to rise and lower in such a manner that the product receiver is opened when the metal tape is lowered. It comprises a product loading mechanism provided with a guide, and a horizontal sealing mechanism that is disposed below the filling cylinder and seals the cylindrical packaging material in the transverse direction.

  According to this bag making filling and packaging apparatus, the cylindrical packaging material that is guided outside the filling cylinder and travels downward is sealed in the transverse direction by the closing means disposed below the filling cylinder to form a bag. The The bag is filled with the product to be packaged through the inside of the filling cylinder. It is also possible to cut and separate the bag filled with the product from the cylindrical packaging material and to close the bag opening by heat sealing or the like. In the bag formed earlier, the bag opening can be closed simultaneously with the formation of the bag bottom by a transverse seal in the subsequent bag. The product loading mechanism individually supports the product as a single article conveyed above the filling cylinder by the product receiver, and lowers the supported product by dropping the metal tape in the filling cylinder so that the product is Since the support of the product is released by opening the product receiver when approaching the, the fall distance of the product to be filled is shortened, and the posture and shape of the product can be prevented from being lost. The bag-filling / packaging device includes a former in which a filling cylinder is suspended and a flat web-shaped packaging material is formed into a cylindrical packaging material, and both side edges of the cylindrical packaging material are sealed. A vertical sealing mechanism can be provided.

  In this bag making filling and packaging apparatus, it is preferable to support the bottom so that the product is loaded from both sides. Therefore, the product charging mechanism is configured by arranging two charging units having the metal tape and the tape guide as a single unit facing each other in the filling cylinder, and both the metal tapes are arranged on the filling cylinder. Ascending / descending drive is performed in synchronism with each other by being drawn downward or wound upwardly from the winding portion disposed above. By configuring in this way, the product is supported so that the product is held from both sides by the product receiver of each metal tape provided in the two charging units arranged opposite to each other in the filling cylinder, and both the metal tapes are synchronized with each other. As a result, the product is stably supported without being out of balance.

  In the bag-filling-packaging apparatus having two charging units, the metal tape is preferably driven so that abrasion powder is not generated as much as possible. Therefore, both the feeding units can be provided with a driving roller that is brought into contact with the metal tape for running or feeding out the metal tape. When the dosing unit is configured in this way, the drive roller causes the metal tape to run with frictional force and winds or feeds the metal tape. Since the driving roller and the metal tape are contacted by rolling frictional force, the product can be put in a clean environment even when the product is food. In this case, it is preferable to drive the metal tape stably by arranging the drive rollers in pairs so as to sandwich the metal tape on both sides.

  In this bag making filling and packaging apparatus, each of the tape guides can be configured to slide and guide the corresponding metal tape in the tape width direction and the tape thickness direction. By sliding and guiding each metal tape in both directions of tape width and tape thickness by each tape guide, both metal tapes do not move in an unstable manner in the lateral direction or in the direction of contact with and away from each other. It can move up and down stably.

  At that time, each of the tape guides includes a guide frame having a U-shaped cross section that slides and guides at least both side edge portions of the metal tape around the side edge from the front side to the back side. Can do. By surrounding at least both side edges of the metal tape with a guide frame having a U-shaped cross section, each metal tape can be slidably guided in both the tape width and the tape thickness.

  Further, in the case of using this U-shaped guide frame, each guide frame guides the frame main body portion extending straight in parallel with the longitudinal direction of the filling cylinder and the tip end portion when the metal tape is lowered. In order to open the product receiver, a frame bending portion that continues downward from the frame main body portion and smoothly bends away from the mating tape guide can be provided. When the tip of both metal tapes descends the frame bend, the two tips are displaced away from each other and the lower end of the metal tape bends along the frame bend. The product support can be released and the product can be dropped.

  In this bag making filling and packaging device, at least the lower outer surface of the filling cylinder is formed in a square cylinder shape, and when the horizontal sealing mechanism seals the cylindrical packaging material in the transverse direction, A square bottom can be formed. By the filling cylinder in which the lower outer surface is formed in a square cross section, the cylindrical packaging material is finally formed in a cross section and a square bottom bag is formed. In this case, it is preferable to positively form the square bottom by appropriately folding the gusset from the side before the sealing in the transverse direction.

  In this bag making filling and packaging apparatus, a product transport mechanism is connected upstream from the product input mechanism, and the product transport mechanism is transported by the transport means and the transport means for transporting the product. A shutter may be provided that receives the product and retracts to a retracted position after the product is delivered to the product loading mechanism at an advanced position close to the upper end of the filling cylinder. By connecting such a product transport mechanism upstream with respect to the product loading mechanism, the product transported by the transport means is received on the shutter, and then advances close to the upper end of the filling cylinder by the shutter. Carried to position. The product is delivered to the product loading mechanism at the advanced position, and the shutter is retracted to the retracted position. The product charging mechanism can be lowered in the filling cylinder while the product is supported.

  The bag making and filling and packaging apparatus according to the present invention is configured as described above, and in particular, a metal tape that moves up and down as a product loading mechanism for feeding products into the bag through the inside of the filling cylinder is fed out or wound up from the winding section. Therefore, the position occupied by the metal tape in the cross-sectional space of the filling cylinder can be brought close to the inner surface of the filling cylinder, and the ratio occupied by the metal tape can be made very small. Accordingly, since the space in the filling cylinder can be used exclusively for the introduction of the product, the diameter of the filling cylinder can be reduced with respect to the size of the product. In addition, since the metal tape can be configured to be wound up, the structure above the filling cylinder is simplified and the space occupied is small. As a result, it is possible to provide a bag-filling and packaging apparatus that can be downsized horizontally and vertically to reduce manufacturing costs. Moreover, since the excess part of a bag can be decreased, the usage-amount of a packaging material can also be decreased. In addition, the product support is released with the product as close as possible to the bottom of the bag, so the product's fall distance is shortened, and the product's posture and shape caused by the product colliding with the bottom of the bag. Can be prevented from collapsing to prevent a decline in merchantability as a package.

  Embodiments of a bag making and filling and packaging apparatus according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing an embodiment of a bag making filling and packaging apparatus according to the present invention, wherein (a) is an overall perspective view, and (b) is a partial perspective view showing a product support state by a product loading mechanism. is there.

And a filling cylinder 3 having a rectangular cross section. The former 2 has a shape similar to that of a former used in a bag filling and packaging apparatus that forms a flat web-shaped packaging material into a cylindrical tubular packaging material in the sailor unit 10, but has an inner circumference. The cylindrical portion 11 on the side is formed in a substantially rectangular tube shape corresponding to the filling tube 3. The filling cylinder 3 has a hollow interior so that the product A can be introduced, and the outer rectangular cylinder surface receives the tubular packaging material Ft formed by the former 2, and the tubular packaging material Ft travels. Can be guided. The bag-making filling and packaging apparatus 1 also has a horizontal seal that forms a square bottom bag B by sealing a cylindrical packaging material Ft that is disposed below the filling cylinder 3 and that has a square cross section formed by the filling cylinder 3 in the transverse direction. It has a mechanism 4.

  The product A to be packaged can be a fragile single item food such as a Japanese confectionery such as a bun or a cake such as a cupcake that is individually packaged in each square bottom bag B, and the quality-preserving agent C is attached to the bottom surface. Yes. A product transport mechanism 5 for feeding the product A is disposed close to the upper end portion 12 of the filling cylinder 3. The product transport mechanism 5 has a shutter 16 that operates to advance the upper end portion 12 of the filling cylinder 3 to an upper position and retreat from the position, and a transport that is disposed upstream of the shutter 16 and transports the product to the shutter 16. Means (refer to FIG. 3 for details). The shutter 16 receives and places the product A on the placement surface 17 that is the upper surface at the advanced position that covers the upper end portion 12 of the filling cylinder 3, and moves back to the retracted position indicated by the imaginary line, thereby placing the product. A is introduced into the filling cylinder 3 from the opening 12a of the upper end portion 12.

  The cylindrical packaging material Ft is sandwiched between the outer surface 14 of the filling cylinder 3 on both the left and right sides of the filling cylinder 3, and the cylindrical packaging material Ft is moved downward with the tubular packaging material Ft pressed against the outer surface 14. A packaging material feeding mechanism 6 for pulling down is disposed. In addition, a vertical sealing mechanism 7 that seals the side edge of the cylindrical packaging material Ft is disposed on the front surface of the filling cylinder 3. The packaging material feeding mechanism 6 and the vertical seal mechanism 7 may have a well-known structure used in a type of bag making and packaging machine having a cylindrical filling section. The packaging material feed mechanism 6 includes, for example, a toothed belt 18 that contacts the cylindrical packaging material Ft with a high frictional force, a toothed driving pulley 19 and a toothed driven pulley 20 around which the toothed belt 18 is wound. It is made up. Since the toothed belt 18 sandwiches the cylindrical packaging material Ft with respect to the flat side surface of the filling cylinder 3 having a rectangular cross section, the cylindrical packaging material Ft can be reliably fed. The vertical seal mechanism 7 includes, for example, a pair of vertical heat seal bars 21 and 22 that heat-seal by sandwiching a side edge when approaching each other.

  The horizontal seal mechanism 4 may have a well-known structure used in a type of bag making and filling and packaging machine having a cylindrical filling section. For example, the upper end of the square bottom bag B formed in advance is provided. A lower set of heat seal bars 23 that are heat-sealed and closed, and an upper set of heat seal bars 24 that form a square bottom of the square bottom bag by heat-sealing the subsequent cylindrical packaging material Ft are provided. . A cutter mechanism 25 that cuts the cylindrical packaging material Ft and cuts the square bottom bag B formed in advance by cutting the tubular packaging material Ft may be provided between the heat seal bars 23 and 24 of both sets.

  Below the lower end portion 13 of the filling cylinder 3, gusset folding mechanisms 8 and 9 are provided above and below the lateral seal mechanism 4, respectively. In this example, the gusset folding mechanism 8 provided above the closing means 4 is arranged in a horizontal posture with the tip sharpened toward the cylindrical packaging material Ft, and is provided on both side surfaces of the cylindrical packaging material Ft having a rectangular cross section. A pair of triangular plates 26, 26 that can be advanced and retracted. Further, the gusset folding mechanism 9 provided below the lateral seal mechanism 4 has a shape in which the side surface smoothly retreats from the upper end toward the cylindrical packaging material Ft, and faces the same both side surfaces of the cylindrical packaging material Ft. A pair of vertical plates 27, 27 that can be advanced and retracted.

  In relation to the filling cylinder 3, a product charging mechanism 40 for lowering the product A to the vicinity of the square bottom of the square bottom bag B is provided. The product charging mechanism 40 is composed of a pair of charging units 41 and 41 arranged to face each other, and each charging unit 41 is shown in the winding unit (not shown in the example shown in FIG. 1) disposed above the filling cylinder 3. 3) and a metal tape 43 that can be moved up and down in the filling cylinder 3 by being drawn downward from the winding portion or wound upward. I have. As shown in FIG. 1 (b), a product receiver 44 is integrally formed at the front end portion 43a of each metal tape 43 by bending at a right angle, and the product receivers 44, 44 is a mode in which the bottom of the product A is held from both sides and placed, and the product A can be supported. In order to wind or feed the metal tape 43, a drive roller 45 is provided above the upper end portion 12 so as to run in contact with the metal tape 43. The drive rollers 45 and 45 are disposed in pairs so as to sandwich the metal tape 43 on both the front and back sides, and the metal tape 43 can travel stably. The driving roller 45 is driven by driving means such as a servo motor. When the drive roller 45 is driven to rotate, the drive roller 45 travels the metal tape 43 with rolling frictional force, so that the generation of wear powder is extremely small, and the product A can be used in a clean environment even when the product A is food. Can be thrown in. In order to wind up the metal tape 43 correctly, a spring for urging the metal tape 43 in the winding direction can be provided on the reel of the winding unit.

  In order to stably guide the raising and lowering of each metal tape 43 and to open the product receiver 44 provided at the front end portion 43a to drop the product A onto the square bottom, a tape guide 50 corresponding to each metal tape 43 is provided. Is provided. FIG. 2 is a view showing an example of a tape guide for guiding a metal tape used in the bag making filling and packaging apparatus shown in FIG. FIG. 2A is a side view of a metal tape and a pair of tape guides for guiding the metal tape, and a cross-sectional view showing a middle portion of the filling cylinder omitted. FIG. 2B is a cross-sectional view taken along line I-- in FIG. It is I sectional drawing, and is a figure which shows the state which is supporting the product A when the product receivers 44 and 44 are located in a frame main-body part. As shown in FIG. 2, the pair of tape guides 50, 50 are arranged to face each other, and are attached to an appropriate frame (not shown) of the packaging device above the upper end portion 12 of the filling cylinder 3, The product A is dropped into the filling cylinder 3 from the upper side to the vicinity of the lower end 13 of the filling cylinder 3, that is, the product A is dropped from the position where the product receivers 44 and 44 receive the product A from the shutter 16 to the corner bottom of the bag. It extends over to the position where it does.

  As shown in the front view of FIG. 2B, each tape guide 50 is composed of guide frames 51, 51 surrounding the side edges 46, 46 of the metal tape 43. The guide frames 51, 51 include a back wall portion 52 that guides the back surface of the metal tape 43 when viewed in cross section, side wall portions 53, 53 that turn around the side edges 46, 46 at both ends of the back wall portion 52, and a side wall portion 53. , 53 to the front side of the metal tape 43 and end edges 54 and 54 for guiding the side edge 46 of the metal tape 43 from the front side. The back wall 52 can connect the side walls 53 and 53 to increase the rigidity of the guide frames 51 and 51. Therefore, the guide frames 51 and 51 can slide-guide the metal tape 43 without restricting the position of the metal tape 43 in the tape width direction and the tape thickness direction. The product receiver 44 formed by bending from the front end portion 43 a of each metal tape 43 extends from between the end edge portions 54, 54 toward the counterpart metal tape 43 side so as not to interfere with the end edge portions 54, 54. ing. Each tape guide 50 is manufactured to be higher in rigidity than the metal tape 43, and can reliably guide the metal tape 43 without shaking in the lateral direction or in the contact / separation direction even when the metal tape 43 moves up and down. . When viewed in the longitudinal direction, the tape guides 50, 50 have frame main body portions 55, 55 that extend straight in a direction parallel to the longitudinal direction of the filling cylinder 3, and frame main body portions 55 below the frame main body portions 55, 55. , 55 and frame bent portions 56 and 56 that are smoothly bent so as to gradually move away from each other.

  According to the bag making filling and packaging apparatus 1, the former 2 forms the flat web-shaped packaging material Fw into a cylindrical packaging material Ft having a substantially square cross section. The tubular packaging material Ft is guided by the outer side surface 14 of the filling cylinder 3 having a rectangular cross section arranged in a hanging manner inside the former 2, and is disposed below the filling cylinder 3. By the horizontal sealing mechanism 4, the square bottom of the square bottom bag B is formed by sealing in the transverse direction. The square bottom bag B is filled with the product A introduced through the inside of the filling cylinder 3. The square bottom bag B is appropriately folded from the side by the gusset folding mechanisms 8 and 9 before the transverse sealing by the lateral sealing mechanism 4. The square bottom bag B filled with the product A is cut and separated from the cylindrical packaging material Ft. Closing of the bag opening of the square bottom bag B1 formed in advance can be performed simultaneously with the formation of the square bottom by the transverse seal in the subsequent square bottom bag B2.

  Since the filling cylinder 3 is already formed in a square cross section from the top, a cross-sectional shape transition portion is not required in the middle, and the length is short despite the formation of the square bottom bag B. Therefore, the descending distance of the product A introduced through the inside of the filling cylinder 3 is shortened, and the height of the bag making filling packaging device 1 can be kept low. Further, the product conveying mechanism 5 for feeding the product A into the filling cylinder 3 is disposed close to the upper end portion 12a of the filling cylinder 3 as shown by the shutter 16, so that the product loading mechanism 40 causes the product A to be discharged. The distance by which the metal tape 43 descends after receiving is shortened as much as possible, and the operating range in which the metal tape 43 moves up and down can be shortened.

  When the product A is fed out while being guided by the tape guides 50 and 50 while being supported by the product receivers 44 and 44, the product A descends to the vicinity of the square bottom of the square bag B. Is done. That is, while the metal tapes 43 and 43 are guided by the frame main body portions 55 and 55 when they are lowered from above, the product receivers 44 and 44 are not opened, and the product A is placed on the product receivers 44 and 44. The descent is continued. Since the frame bent portions 56, 56 have a shape that gradually opens downward, the metal tapes 43, 43 are guided by the frame bent portions 56, 56 and lowered, so that the tip portions 43a of the metal tapes 43, 43 are lowered. , 43a are bent in accordance with the shape of the frame bent portions 56, 56, and the product receivers 44, 44 projecting at right angles to the front end portions 43a, 43a are as shown by the imaginary line in FIG. Open the product A, unload the product A, and drop the product A into a bag having a square bottom. After dropping the product A, the metal tapes 43 and 43 rise to the supply position of the product A while being guided by the tape guides 50 and 50, and the above steps are repeated thereafter.

  Since the metal tapes 43 and 43 are moved up and down in a state where they are thin and close to the inner surface of the filling cylinder 3, the space required for the metal tapes 43 and 43 to pass is close to the inner surface of the filling cylinder 3 and in a narrow range. The space in the filling cylinder 3 is limited, and is substantially provided as a space necessary for charging the product A. Therefore, the size of the filling cylinder 3 in the cross section can be minimized, the lateral size of the bag making filling and packaging apparatus 1 can be reduced, and the amount of packaging material required for packaging the product A can be suppressed. Even if product A is a fragile and individually packaged item such as a Japanese confectionery such as a bun or a cupcake, etc., the distance that the product A actually falls after the support of the product A by the product receiver 44 is released Therefore, it is possible to prevent the posture and shape of the product A from collapsing when the product A is filled into the square bottom bag B.

  FIG. 3 is a perspective view showing an upper portion of the bag making filling and packaging apparatus including a product transport mechanism and a product loading mechanism in the bag making filling and packaging apparatus shown in FIG. The description overlapping with the description in the bag making filling and packaging apparatus shown in FIG. 1 is omitted. The product transport mechanism 30 is disposed above the filling cylinder 3, and supplies a supply conveyor 31 that sequentially supplies the products A, a shutter 32 that places the products A supplied one by one from the supply conveyor 31, and a shutter. And a pusher 33 for feeding the product A on the position 32 to a position directly above the filling cylinder 3. The product A on the shutter 32 is moved onto the already-exposed shutter 16 and sent to the transfer position to the product loading mechanism 40 by the pusher 33. Above the filling cylinder 3, winding parts 42, 42 are shown facing each other. The metal tapes 43, 43 fed out from the winding portions 42, 42 are inserted into tape guides 50 that extend straight downward while being parallel to each other and are arranged in the filling cylinder 3. Even if the metal tapes 43 and 43 are wound up and the product receivers 44 and 44 are raised to the uppermost position, the metal tapes 43 and 43 are not detached from the tape guide 50. The product receivers 44 and 44 receive the product A on the shutter 16 at a position raised to the uppermost position. During the operation of the shutter 16, the product A can be accurately transferred onto the product receivers 44 by restricting the product A at positions before and after the operation direction of the shutter 16. After that, when the metal tapes 43 and 43 are fed out, the product receivers 44 and 44 are lowered, and the product A is supported while the product A is supported. The product receivers 44, 44 are opened and the product A is loaded.

  In each of the above-described embodiments, the filling cylinder 3 has a rectangular cross section. However, the filling cylinder 3 may be a cross section cylindrical in the length direction, or a cylinder that changes from a cross section cylindrical to a cross section square in the middle. It is clear that it is good.
