Description

  The present invention relates to a technique for improving a filling chute (chute for filling (injecting) a filling material into a packaging bag) used in a vertical automatic filling and packaging machine.

  Conventionally, when forming a bag by forming a packaging film into a bag shape and automatically filling a filling material (contents) such as a powdery or granular raw material into the bag, the longitudinal length as described in Patent Document 1 is used. Automatic mold filling and packaging machines are used.

  In such a vertical automatic filling and packaging machine, a function as a guide for forming a bag by folding a wrapping packaging film in half, and a function as a guide tube for guiding (filling) powdery raw materials into the bag ( And a filling chute (see reference numeral 5 in FIG. 8) has been used.

Japanese Utility Model Publication No. 50-31158

  However, in such a conventional vertical automatic filling and packaging machine having a relatively simple and inexpensive configuration (see, for example, FIG. 1, FIG. 2, FIG. 8, etc.), powdery raw material (or granular raw material) is contained in the packaging film. In the automatic filling using the filling chute (see reference numeral 5 in FIG. 8), the following problems have occurred.

  As shown in FIG. 8, the powdery raw material received by the funnel portion 51 of the filling chute 5 slides obliquely downward along the bottom (inclined surface) 51 </ b> A of the funnel portion 51 of the filling chute 5. It collides with the vertical wall 52A in the tubular (elliptical cross section) chute part (guidance part) 52 facing the extension line in the dropping direction with momentum, and then falls downward while being unevenly distributed in the vicinity. It is unevenly distributed while leaning on the left vertical side in the bag, and is piled up in a mountain shape.

  In this way, since the powder material is unevenly filled in the bag, conventionally, it is necessary to make the bag longer in the length direction (vertical direction in FIG. 8), which is a factor in increasing the cost of the packaging film. There is a fact that becomes.

  In order to suppress the uneven distribution of the powdery material in the bag as described above, for example, a method of applying vibration and leveling is also conceivable. However, in the case of applying vibration, the packaging film is overlaid and heat-sealed. In addition, there is a real situation that it is not practical because there is a possibility that a fine wrinkle is generated in the seal portion.

  There is also a method of pushing the powdery material into the bag using an auger screw device, but since the applicable powdery material is limited, for example, ingredients (for example, ingredients such as instant miso soup and ramen (dried In the case of powdered materials that include green onions, seaweed, chopped paste, etc.)), the ingredients will be crushed by the screw, so use a filling chute that utilizes the free fall of the powdered material as shown in FIG. There is a fact that the filling method that had been used must be adopted.

In recent years, the cost awareness of the industry has increased, and it is required to reduce the size of the packaging bag relative to the filling amount using an existing vertical automatic filling and packaging machine.
In order to meet this demand, as shown in FIG. 9, when the length of the packaging bag (vertical length in FIG. 9) is set short, there is a possibility that the powdery raw material may be caught in the lateral seal portion F5 of the packaging bag. There is a fact that there is a risk of causing defective products.

  The present invention has been made in view of the above-described various circumstances, and improves a vertical automatic filling and packaging machine that uses a filling chute to fill the contents (filling material) with a simple and low-cost method. Therefore, it is possible to eliminate the content unevenness in the bag at the time of filling, thereby suppressing the occurrence of defective products due to the biting of the content into the lateral seal portion, and It is an object of the present invention to provide a filling chute for a vertical automatic filling and packaging machine that can contribute to the realization of bag making of an appropriate size (length) with respect to the filling amount and, in turn, to the reduction of packaging film costs.

For this reason, the present invention

A forming part for forming a reversible packaging film conveyed from above into a bag shape,
A funnel that receives the falling filling material and discharges it diagonally downward;
A chute part for guiding the filling material discharged from the funnel part to the inside and dropping it into the bag part,
Comprising
A filling material dropping position adjusting member that guides and adjusts the falling position of the filling material from the end in the bag width direction to the center in the bag width direction is provided inside the chute.

In the present invention,
The filling material drop position adjusting member is
Formed by a plate extending in the vertical direction along the inner surface of the chute facing the discharge direction of the filling material from the funnel,
The lower end side may be provided with a return portion formed so as to go from the end portion in the bag width direction to the center in the bag width direction.

In the present invention,
The filling material drop position adjusting member is
A hook portion that can be engaged with an engaging portion in the filling chute is provided on the upper end side.

  In the present invention, the return portion may be formed with a notch for adjusting the amount of the filling material dropped with respect to each position in the bag portion inner width direction.

  According to the present invention, the contents in the bag at the time of filling are improved by improving the vertical automatic filling apparatus of the method of filling the contents (filling material) using the filling chute by a simple and low-cost method. The unevenness of the object can be eliminated, so that the occurrence of defective products due to the biting of the contents into the horizontal seal portion can be suppressed, and the appropriate size (length) with respect to the filling amount of the contents It is possible to provide a filling chute for a vertical automatic filling and packaging machine that can contribute to the realization of bag making and the reduction of packaging film costs.

  Hereinafter, an embodiment according to the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the embodiments described below.

  The basic configuration of a vertical automatic filling and packaging machine 1 according to an embodiment of the present invention can be the same as that of an automatic filling and packaging machine of a type having a filling chute as described in Patent Document 1, for example. .

  As shown in FIGS. 1 and 2, the vertical automatic filling and packaging machine 1 is a raw material supply device provided below a hopper 4A in which contents to be filled (for example, a powdery raw material or a granular raw material) are accommodated. (Measuring turntable) 4, filling chute 5, heat seal device (L-shaped seal fitting) 6, and packaging bag feed device (feed roll) 7.

  In addition, the packaging film that is sequentially fed from the raw roll 2 around which the packaging film is wound via the packaging material feeding device 3 is, for example, a base film such as PET, heat such as polyethylene having a melting point lower than that of the base film. It can be composed of a seal film. In addition, the packaging film may have a three-layer structure including a base film, an intermediate film, and a heat seal film.

  As shown in FIG. 3 (A), in the vertical automatic filling and packaging machine 1, the reverse packaging film F1 drawn out from the original fabric roll 2 is moved downward in FIG. 3 (A) by the packaging material guide 31. The direction is changed, the sheet is conveyed, and proceeds while being folded into two substantially U-shaped at the center in the width direction along the outer shape of the forming portion 53 of the filling chute 5 (the left portion in FIG. 3A).

  The folded packaging film F2 is introduced into a heat seal device (L-type seal fitting) 6 installed immediately below the filling chute 5, and the heat seal device (L-type seal fitting) 6 is substantially U-shaped. The folded packaging film F2 is sandwiched to operate so as to perform vertical heat sealing and horizontal heat sealing at the same time, thereby forming an upper opening bag portion F6.

  The heat seal device (L-shaped seal fitting) 6 is configured in a bowl shape as shown in FIG. 4, for example, and sandwiched in a substantially U-shaped packaging film F2 as shown in FIG. 3 (B). Such a side seal portion (vertical seal portion) F4 and a top seal portion (horizontal seal portion) F5 (corresponding to F5 on the lower side of FIG. 3A) are formed in an L shape at the same time. Yes.

  The hopper 4A contains a filling material (content, for example, powdery or granular raw material), and this filling material is a raw material supply provided at the lower end of the hopper 4A as shown in FIG. After being accommodated in the accommodating portion (metering hole) 42 of the device (metering turntable) 4 and metered to a predetermined amount, the rotating portion 41 that is substantially integral with the accommodating portion 42 is rotated to move the accommodating portion 42 below the turntable. It is made to correspond with the opening part 43A of the board 43, and, thereby, the filling material in the accommodating part 42 falls freely to the funnel part 51 of the filling chute 5.

  Then, the filling material received by the funnel portion 51 of the filling chute 5 freely falls obliquely downward along the bottom of the funnel portion 51 of the filling chute 5, and then the cylindrical chute (cross-sectionally oval cylindrical) filling chute 5. It is guided to the chute part (falling part, guiding part) 52 and charged into the bag part F6 of the packaging film. Note that the vicinity of the lower end of the oval cylindrical chute portion (guidance portion) 52 of the filling chute 5 is in a state of being inserted inside the bag portion F6 of the upper opening.

  Here, as the filling material (contents), a powdery, granular raw material, a lump of a somewhat large size (for example, drying ingredients such as instant miso soup and soup and instant noodles), or a mixture thereof is assumed. Can do.

  The packaging film including the bag portion F6 filled with the filling material (contents) in this way is conveyed downward by one bag by the packaging bag feeding device (feeding roll) 7, and then again the heat sealing device (L A side seal portion (vertical seal portion) F4 and a top seal portion (horizontal seal portion) F5 are formed by being sandwiched by the mold seal fitting) 6, and the upper portion of the bag portion F6 filled with the contents is hermetically sealed. ing.

  By repeating the above-described operation, a plurality of bag portions F6 filled with the contents are formed in series along the conveyance direction of the packaging film (see FIG. 3A and the like).

Next, the packaging bag F3 in a continuous state (a state in which a plurality of individual packaging bags are connected) is guided to the cutter device 8, and is near the center in the vertical direction in FIG. 3A of the top seal portion (lateral seal portion) F5. On the other hand, perforation processing or separation processing is applied to form individual packaging bags (products).
Then, the separated packaging bag (product) is carried out to the outside through the carry-out slide 9.

  Reference numeral 10 denotes a control panel (operation panel) for operating the vertical automatic packaging machine 1, and reference numeral 11 denotes a control BOX in which a control device and the like are built.

  Here, in this embodiment, in order to suppress the bias when filling the bag part F6 of the packaging film with the contents (filling material, for example, powdery or granular raw material) via the filling chute 5, the following is performed. It has a simple configuration.

  That is, as described with reference to FIG. 8A and the like, the filling material that has fallen freely downward obliquely along the bottom portion (inclined surface) 51A of the funnel portion 51 of the filling chute 5 is the bottom portion (inclined surface) of the funnel portion 51. 51A jumps off and collides with the vertical wall 52A of the chute part (guidance part) 52, but in this embodiment, as shown in FIG. A filling material drop position guiding member (filling material fall position adjusting member) 100 is provided.

  The filling material drop position guiding member (guidance plate) 100 is distributed unevenly in the bag with respect to the filling material that is unevenly distributed in the filling chute 5 (filling chute portion 52) and falls freely. It functions to adjust (regulate) the falling direction.

  Specifically, the filling material that has jumped out of the funnel portion 51 travels toward the vertical wall 52A of the chute portion (guidance portion) 52 of the filling chute 5, and then moves downward along the opposing vertical wall 52A. Since the filling material is biased in the bag portion F6, at least a part of the filling material that is about to fall along the outer vertical wall 52A is prevented from dropping along the vertical wall 52A. That is, the tip (lower end side) of the chute part (induction part) 52 (in the bag part F6) is returned from the outer side to the center side (inner side) so as to return to the center side (inner side). 100 A of return parts formed so that it may go to.

  When such a filling material drop position guiding member (guide plate) 100 (return portion 100A) is provided, the filling material does not fall substantially vertically downward along the vertical wall 52A, and the filling material is shown in FIG. ) And (B), it falls to the chute part (guidance part) 52 or near the center in the width direction in the bag part F6.

  When the filling material falls in the vicinity of the center in the width direction, the filling material stacked in the bag portion F6 can be collapsed on either side in the left-right direction in FIG. It is possible to suppress bulky accumulation as in the case where the guide plate) 100 (the return portion 100A) is not provided and the left end in the bag portion F6 is biased and filled as in the conventional case.

  That is, in the prior art without the filling material drop position guide member (guide plate) 100 (return portion 100A), the filling material that is biased to the left end (see FIG. 5) in the bag portion F6 is placed on the left side from the left end side. Since the filling material cannot collapse, the filling material will be piled up bulky with a bias toward the left end in the bag portion F6, but this implementation is such that the dropping position of the filling material can be adjusted near the center in the bag width direction. According to this form, it is possible to suppress the occurrence of a phenomenon that the filling material is piled up in bulk.

  Therefore, according to the present embodiment, it is possible to eliminate the uneven content in the bag at the time of filling while having a simple and low-cost configuration, and thus the biting of the content into the lateral seal portion. In addition to suppressing the generation of defective products due to filling, it is possible to contribute to the reduction of packaging film costs by realizing the bag making of an appropriate size (length) with respect to the filling amount of the contents.

  In FIG. 5, the filling material drop position guide member (guide plate) 100 is extended from the upper side of the filling chute 5 to the lower end, but this is an existing (pre-paid) vertical automatic filling and packaging machine. Without removing one filling chute 5, an operator can insert a filling material drop position guide member (guide plate) 100 from above and fix it to the filling chute 5 main body with an adhesive or the like at a predetermined position, or it can be processed. This is because it can be easily fixed to the main body of the filling chute 5 by a method such as bolt fastening at a position.

  Therefore, if the filling chute 5 is removed from the existing (pre-paid) vertical automatic filling and packaging machine 1 and the filling material drop position guiding member (guide plate) 100 is attached, or a new vertical automatic filling and packaging machine is installed. In the case of delivering 1 or the like, the filling material drop position guide member (guide plate) 100 can have a length substantially equal to the vertical wall 52A portion of the chute portion (guide portion) 52 of FIG. Is.

  By the way, the filling material drop position guide member (guide plate) 100 (returning part 100A) has a shape (inclination or width direction from the outer side) of the returning part 100A depending on the properties (properties or state), type, composition, etc. of the filling material. It is assumed that there is a case where it is desired to change the return amount toward the center side (inner side).

  Further, depending on the filling material, it may be easily adhered. In such a case, it may be desired to remove the filling material drop position guide member (guide plate) 100 (return portion 100A) from the filling chute 5 and clean it. is assumed.

  For this reason, it is beneficial for the user if the filling material drop position guide member (guide plate) can be easily attached to and detached from the filling chute 5 of the existing (already delivered) vertical automatic filling and packaging machine 1.

  For example, as shown in FIG. 5, a filling material drop position guide member (guide plate) 101 having a detachable configuration using a hook can be employed.

  The filler material drop position guide member (guide plate) 101 is inserted into the hook engaging portion (annular element) 103 by the operator inserting the lower end (return portion 101A) of the filler material drop position guide member (guide plate) 101 from above. It is configured to be attached to the main body of the filling chute 5 by being inserted downward and engaging a hook portion (saddle-shaped portion) 102 formed at the upper end of the filling material drop position guiding member (guide plate) 101. Yes.

  Then, the hook part (hook-like part) 102 formed at the upper end of the filling material drop position guide member (guide plate) 101 is lifted upward to disengage the hook engaging part (annular element) 103, and The filling material drop position guide member (guide plate) 101 can be easily removed from the filling chute 5 main body.

  According to such a configuration, the hook engaging portion (annular element) 103 is simply attached to the inside of the filling chute 5 by a simple method such as fastening or bonding, and then the existing (already delivered) vertical automatic filling and packaging machine 1 is filled. The filling material drop position guide member (guide plate) 101 can be easily attached to and detached from the chute 5 and can be easily replaced with the filling material drop position guide member (guide plate) 101 of the return portion 101A having a different shape. The filling material drop position guide member (guide plate) 101 can be cleaned.

  Further, hook engaging portions (annular elements) 103 are attached at different positions in the height direction (vertical direction in FIG. 3A), or filling material dropping position guide members (guide plates) 101 having different lengths are provided. By preparing, the height direction attachment position of the filling material drop position guide member (guide plate) 101 and the height direction attachment position of the return portion 101A can be changed.

  If the height direction attachment position of the return portion 101A (or return portion 100A) is changed, the falling position of the filling material can be adjusted as shown in FIGS. 6A and 6B. Depending on the type and the like, it is possible to suppress the occurrence of a phenomenon that the filling material is unevenly distributed in the bag portion F6 and the filling material is bulky and accumulates in a mountain shape.

  In addition, the shape of the return portion 101A (or the return portion 100A) can be changed as appropriate. For example, from the plain shape (flat shape) return portion 104 shown in FIG. For example, the tip may have a cracked shape with the tip divided into two or more branches as shown in FIG. As shown in FIG. 7B, the tip can be divided into two and the central cutout 105 can be formed to extend in parallel in the longitudinal direction. Further, as shown in FIG. 7C, the tip can be divided into two forks, and the cutout portion 106 at the center can be formed to have a divergent shape in which the opening is widened toward the tip. In addition, the notches 105 and 106 have a function of adjusting the amount of dropping (dropping degree) of the filling material with respect to each position in the width direction in the bag portion F6.

  That is, for example, in the case of the shape as shown in FIG. 7B (or FIG. 7E), as shown in FIG. The filling material that falls (toward the left side) and the filling material that does not fall from the notch 105 but is transported to the tip side and then falls late and falls near the center in the width direction of the bag portion F6 are mixed. Therefore, as compared with, for example, the plain-shaped return portion of FIG. 7A, the bias in the bag portion F6 of the filling material can be further suppressed depending on the property or type of the filling material.

  As described above, according to the present embodiment, since the filling material drop position guide member (guide plate) 100 or 101 is provided, the conventional phenomenon (the bottom of the funnel portion 51 of the filling chute 5 (inclination) Surface) 51A, it slides diagonally downward and falls, and collides with the vertical wall 52A in the cylindrical (section ellipse) chute part (guidance part) 52 facing the extension line in the dropping direction with its momentum, Thereafter, the filling material unevenly distributed in the vicinity and falling downward can suppress the occurrence of a phenomenon in which the filling material is unevenly distributed in the bag portion F6 and accumulated in a bulky shape.

  Therefore, according to the present embodiment, since the filling material is suppressed from being biased in the bag portion F6, the bag is shortened in the length direction (vertical direction in FIG. 3) to make a bag. Therefore, the amount of packaging film used can be reduced, which can contribute to cost reduction.

  Moreover, according to this Embodiment, there is no possibility that a filling material may bite into the horizontal seal part of a packaging bag, and generation | occurrence | production of inferior goods can be suppressed.

  Further, according to the present embodiment, since only a simple filling material drop position guide member (guide plate) 100 or 101 is attached, the existing vertical automatic filling device can be used as it is by simple improvement, There is an advantage that it can be handled at low cost.

  That is, according to the present embodiment, the vertical automatic filling device of the method of filling the contents (filling material) using the filling chute can be improved by a simple and low-cost method. Unevenness of contents (filling material) in the bag can be eliminated, and the occurrence of defective products due to biting of the contents (filling material) into the lateral seal can be suppressed. Realization of a bag having an appropriate size (length) with respect to the filling amount of the product can contribute to reduction of packaging film costs.

  In addition, as the material of the filling material drop position guide member (guide plate) 100 or 101, metals such as stainless steel, aluminum, and titanium can be adopted, but resin-based materials such as Teflon (registered trademark) are used. Is also possible.

  The embodiment described above is merely an example for explaining the present invention, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
