Abstract
A multiple-line automatic packing machine configured to produce packed products each having three sealed sides simultaneously and continuously in multiple lines. A vertical sealing device includes a vertical sealing belt. Vertical sealing is performed by rotating the vertical sealing belt along a conveying direction of the packing film at the same speed as conveying speed of the packing film while pressing the vertical sealing belt against a former through intermediation of an overlapping portion of the packing film. Further, a lateral sealing device performs lateral sealing on a portion of the packing film corresponding to a lower portion of a packing bag, and then performs lateral sealing on a portion of the packing film corresponding to an upper portion of the packing bag while moving upward and downward in synchronization with the packing film continuously conveyed at a predetermined speed.
Description
- The present invention belongs to a technical field of an automatic packing machine configured to automatically fill and pack a material to be packed (content) using a packing film (packing material). More specifically, the present invention relates to a multiple-line (multiple-string) automatic packing machine configured to slit a band-like packing film into a plurality of strips, and to form packing bags using the plurality of slit packing films.
- As disclosed in, for example,
Patent Literature 1, a related-art multiple-line (multiple-string) automatic packing machine is configured to continuously perform slitting of a take-up packing material, which is obtained by uniformly performing printing on a wide sheet film, into strips in accordance with the number of lines, vertical sealing, lateral sealing, filling of a material to be packed, and cutting. - Further, a configuration of the above-mentioned related-art multiple-line automatic packing machine is described with reference to
FIG. 5 . Reference symbol F denotes a take-up roll obtained by taking up a wide printed packing material FX; AS and AT, packing material feed rollers rotated by a motor (not shown); BX, a slitter configured to slit the above-mentioned packing material FX into a plurality of packing films Fa between a roller B and the slitter; and Ca and Cb, guide rollers. - Still further, reference symbol D denotes a plurality of supply pipes arranged in line at equal intervals in a lateral direction and configured to fill the material to be packed; E, a forming member configured to wind and wrap each fed packing film Fa around a periphery of each supply pipe D; X, vertical sealers (vertical sealing device) configured to perform vertical sealing on both edges of each packing film Fa, thereby forming the entire packing film Fa into a cylindrical shape; and Y, lateral sealers (lateral sealing device) configured to perform lateral sealing on each packing film Fa subjected to vertical sealing and formed into a cylindrical shape. When the lateral sealers Y perform lateral sealing, the material to be packed is filled through each supply pipe D into each packing film Fa formed into a bag shape by sealing. Then, while performing lateral sealing, the lateral sealers Y move downward by a length corresponding to one bag, thereby drawing one bag from each packing film Fa.
- Next, under a state in which the above-mentioned lateral sealers Y are laterally separated from each other to cancel lateral sealing, the lateral sealers Y move upward, and are returned to positions before performing the above-mentioned lateral sealing. The lateral sealers Y perform lateral sealing again, thereby sealing an opening of each bag into which the material to be packed is filled. Further, cutters (not shown) cut a center line of the lateral sealed portion into upper and lower parts. Thus, a process of multi-string sealing is finished.
- In
FIG. 5 , reference symbol P denotes a packed product formed by the above-mentioned multiple-line automatic packing machine into a stick-like shape by sealing; Pa, a vertical sealed portion of the packed product; and Pc and Pb, upper and lower lateral sealed portions cut by the cutters. - [PTL 1] JP 58-54327 Y2
- [PTL 2] JP 3585638 B2
- As described above, the multiple-line automatic packing machine has such an advantage that the large number of stick-like packed products can be automatically packed at one time. However, when a size (length) of the packed products is changed, it is necessary to adjust upward and downward movement amounts of the lateral sealers Y in accordance with the size.
- However, in the related-art automatic packing machine, a rotary crank mechanism is used as means for moving the lateral sealers Y upward and downward. When a length of a bag is changed, it is necessary to adjust a radius of rotation of the crank. In addition, using a rotary differential gear unit, a timing setting cam, or the like, it is necessary to adjust a timing of filling the material to be packed and a timing of cutting performed by the cutters every time the length of the bag is changed. Manipulation of the rotary differential gear unit and the timing setting cam requires time and labor, and is significantly troublesome.
- Further, even after finish of the above-mentioned adjusting operations, a proper size and a proper filling amount of the bag cannot be obtained unless trial sealing is repeated for some time while an actual dimension is measured using a measure or the like, and adjusting is repeated while a weight is measured using a weighing machine. Thus, there is a problem in that the adjusting operations become more and more complicated, and require longer time. In addition, there is also a problem in that a large amount of the material to be packed and a large amount of the packing material FX are wasted for trial sealing performed for the adjusting operations. Measures against the problems have been desired.
- In this context, as described in
Patent Literature 2, the inventors of the present invention have proposed a technology of moving the lateral sealers Y upward and downward using an electric driving motor, movable pulleys mounted to the lateral sealers Y, fixed pulleys fixed to a frame side, and a timing belt, a chain, or the like stretched over the pulleys instead of using the rotary crank mechanism as means for moving the lateral sealers Y upward and downward. - According to an automatic packing machine disclosed in
Patent Literature 2, upward and downward movement of the lateral sealers Y can be set to arbitrary speed with a high degree of freedom independently of feeding speed of the film, a timing of filling the material to be packed, and the like. Accordingly, even when the size (length) of each packed product is changed, adjustment is easily performed, with the result that the adjusting operations can be shortened and a waste of the material to be packed and the packing material FX can be prevented. - However, in the automatic packing machine disclosed in
Patent Literature 2, when vertical sealing is performed, it is necessary to provide an advancing/retreating mechanism (reciprocating mechanism) configured to cause a vertical sealer to perform vertical sealing by moving the vertical sealer close to the packing film in a direction orthogonal to a plane of conveyance of the packing film so as to bring the vertical sealer into contact with the packing film, and then retreat the vertical sealer from the packing film. The mechanism is complicated, and has a configuration unsuitable for increase in speed because the mechanism causes relatively large vibration, relatively loud noise, and the like. In addition, while vertical sealing is performed, it is necessary to temporarily stop feeding (conveyance) of the packing film. In actuality, there has been desired further improvement such as simplification of the configuration and improvement in productivity. - The present invention has been made in view of the above-mentioned circumstances, and has an object to provide a multiple-line automatic packing machine capable of, with a simple and low-cost configuration thereof, automatically packing stick-like packed products in multiple lines while continuously feeding a packing film at a predetermined speed without temporarily stopping the feeding.
- Thus, according to one embodiment of the present invention, there is provided a multiple-line automatic packing machine, including:
- a former having a cylindrical shape;
a vertical sealing device;
a lateral sealing device; and
a raw material filling device,
the multiple-line automatic packing machine being configured to produce packed products each having three sealed sides simultaneously and continuously in multiple lines through the procedures of: - slitting a strip of a wide packing film into a plurality of strips along a conveying direction of the wide packing film to form the wide packing film into multiple packing films;
- forming each of the multiple packing films, which is continuously conveyed at a predetermined speed, into substantially a cylindrical shape by winding the each of the multiple packing films around an outer periphery of the former arranged along the conveying direction;
- overlapping open sides of the each of the multiple packing films;
- performing vertical sealing on the overlapping portion of the each of the multiple packing films to form the each of the multiple packing films into a cylindrical packing bag;
- performing lateral sealing on the each of the multiple packing films by the lateral sealing device;
- filling a content into the cylindrical packing bag by the raw material filling device; and
- sealing the cylindrical packing bag by performing lateral sealing on an upper portion of the cylindrical packing bag,
- the vertical sealing device including a vertical sealing belt controlled at a predetermined temperature,
the vertical sealing device being configured to perform vertical sealing while pressing the vertical sealing belt against the former through intermediation of the overlapping portion, and rotating the vertical sealing belt along the conveying direction of the each of the multiple packing films at the same speed as speed of the each of the multiple packing films continuously conveyed at the predetermined speed,
the lateral sealing device being configured to perform lateral sealing on a portion of the each of the multiple packing films corresponding to a lower portion of the cylindrical packing bag, and then perform lateral sealing on a portion of the each of the multiple packing films corresponding to an upper portion of the cylindrical packing bag while moving upward and downward in synchronization with the each of the multiple packing films continuously conveyed at the predetermined speed. - In one embodiment of the present invention, the vertical sealing device may include a driving motor configured to rotationally drive the vertical sealing belt.
- In one embodiment of the present invention, the multiple-line automatic packing machine may further include a vertical sealing feed unit including a vertical sealing feed belt that is arranged around the former, and is rotated along the conveying direction of the each of the multiple packing films at the same speed as the speed of the each of the multiple packing films continuously conveyed at the predetermined speed under a state in which the vertical sealing feed belt and the former sandwich the each of the multiple packing films therebetween.
- According to the present invention, it is possible to provide the multiple-line automatic packing machine capable of, with the simple and low-cost configuration thereof, slitting the packing film into multiple strips, and automatically producing the packing bags each having four sealed sides simultaneously in multiple lines (a plurality of parallel lines) using the slit packing films.

Note that, the present invention is not limited to the embodiment described below.
-
FIG. 1 is a front view for illustrating an external appearance of a multiple-line (multiple-string) automatic packing machine according to the present invention, andFIG. 2 is a side view for illustrating the internal structure of the multiple-line automatic packing machine. In those drawings,reference symbol 1 denotes an entire machine body of the multiple-line automatic packing machine; 2, a hopper containing therein various kinds of materials to be packed, such as liquid, powder, and a viscous body; and 2T, a supply passage connected to thehopper 2. -
Reference symbol 10 denotes an input device configured to input various kinds of data to a controller, andreference symbol 11 denotes a packing material shaft configured to support a packing film pulled out from a packing film roll F while applying predetermined tension to the packing film. - Further,
reference symbol 3 denotes a filling device configured to fill the material to be packed (content to be packed into a packing bag) and mounted to a lower end of thesupply passage 2T. The content, which is measured for each packing bag by a measuringboard 3K moved by a fillingair cylinder 3A in a reciprocating manner, is supplied into achute 4 at a predetermined timing so as to correspond to each packing bag. - As illustrated in
FIG. 2 , in this embodiment, a strip of a wide packing film F1 taken up into the packing film roll F is fed by a packingmaterial feed device 12 at a predetermined speed continually (without temporarily stopping or unintermittently), and a packing film F2 fed continually (without temporarily stopping) is slit (divided) by a packingmaterial slitting device 13 into four strips. Each of four divided packing films F3 is wrapped (wound) around an outer periphery of a hollow cylindrical former 5 from both sides of the former. Thus, the packing films F3 are each formed into substantially a cylindrical shape. Each of the four slit packing films is subjected to vertical sealing, lateral sealing, content filling, and the like by devices provided for each of the four slit packing films, thereby being manufactured into a packing bag. - Under a state in which each packing film F4 formed into a cylindrical shape is wound into substantially a cylindrical shape around the outer periphery of the former 5, back surfaces of both sides (open ends) of the packing film F4 are superposed on each other so as to be opposed to each other at a superposed portion (overlapping portion) P, and then the packing film F4 is fed into a triple belt-type
vertical sealing device 6. The triple belt-typevertical sealing device 6 performs vertical sealing on the superposed portion P, thereby forming a packing film F5 having substantially a cylindrical shape. The packing film to be used in the present invention refers to a packing film obtained in such a manner that back surfaces of the packing film are bonded to each other by heat sealing under a state in which the back surfaces of the packing film are opposed to each other similarly to the case of the superposed portion P. Even when front surfaces of the packing film, or the front surface and the back surface of the packing film are subjected to heat sealing in a superposed state, the front surfaces of the packing film, or the front surface and the back surface of the packing film are not bonded to each other. - As illustrated in
FIG. 2 andFIG. 3(A) toFIG. 3(C) , in the triple belt-typevertical sealing device 6, a belt-typevertical sealing unit 61 is arranged at a position corresponding to the superposed portion P of the packing film F4 wound into substantially a cylindrical shape around the former 5. - As illustrated in
FIG. 3(C) , the belt-typevertical sealing unit 61 includes a verticalsealing unit base 64, an electrothermal heater fitting 614 mounted to the verticalsealing unit base 64 and heated to and kept at a predetermined temperature, avertical sealing belt 611 held in abutment on the electrothermal heater fitting 614 and controlled at the predetermined temperature, and vertical sealing belt pulleys 612 and 613 over which thevertical sealing belt 611 is stretched. A vertical sealing belt drivengear 618 is integrally mounted to the vertical sealing belt pulley 613, and a vertical sealingbelt driving gear 617 is meshed with the vertical sealing belt drivengear 618. Thevertical sealing belt 611 is arranged so as to be rotated along a conveying direction of the packing film F4. - Further, as illustrated in
FIG. 3(A) , a vertical sealing belt driving motor 65 is coupled to the vertical sealingbelt driving gear 617 in a rotating manner. Rotation speed of the vertical sealing belt driving motor 65 is controlled to the same speed as feeding speed (conveying speed) of the packing film. - According to the belt-type
vertical sealing unit 61 having the above-mentioned configuration, vertical sealing can be performed on the superposed portion P between the both sides (open ends) of the packing film F4, which is wound into substantially a cylindrical shape around the outer periphery of the former 5, in such a manner that thevertical sealing belt 611 increased in temperature by the electrothermal heater fitting 614 is pressed against the outer periphery of the former 5 through intermediation of the superposed portion P (seeFIG. 4(C) ). At this time, thevertical sealing belt 611 is rotationally driven in accordance with the conveying speed of the packing film F4. Accordingly, unlike the related art, it is not necessary to temporarily stop feeding (conveyance) of the packing film when performing vertical sealing, thereby being capable of increasing production efficiency. - Further, the belt-type
vertical sealing unit 61 according to this embodiment performs vertical sealing while rotating the belt heated to the predetermined temperature along the conveying direction of the packing film. Accordingly, unlike the related art, when vertical sealing is performed, it is not necessary to provide a complicated advancing/retreating mechanism (reciprocating mechanism) configured to cause a vertical sealer to perform vertical sealing by moving the vertical sealer close to the packing film in a direction orthogonal to a plane of conveyance of the packing film so as to bring the vertical sealer into contact with the packing film, and then retreat the vertical sealer from the packing film. Consequently, simplification of the configuration can be promoted, and the belt-typevertical sealing unit 61 can contribute to reduction in vibration, noise, and the like, and to increase in conveying speed of the packing film. - As illustrated in
FIG. 3(A) toFIG. 3(C) , in the triple belt-typevertical sealing device 6 according to this embodiment, as a pair of right and left units opposed to each other, a right verticalsealing feed unit 63 and a left verticalsealing feed unit 62 are arranged on both right and left sides of the belt-typevertical sealing unit 61 in a diameter direction of the former 5, respectively. - In this embodiment, at least one of the left vertical
sealing feed unit 62 or the right verticalsealing feed unit 63 corresponds to a vertical sealing feed unit according to the present invention. - As illustrated in
FIG. 3(B) , the left vertical sealing feed unit 62 (right vertical sealing feed unit 63) includes a left vertical sealing feed belt 621 (right vertical sealing feed belt 631) rotated along the conveying direction of the packing film F4, and the left vertical sealing feed belt 621 (right vertical sealing feed belt 631) is stretched over left vertical sealing feed belt pulleys 622, 623, 624, and 625 (right vertical sealing feed belt pulleys 632, 633, 634, and 635), and is configured to press the packing film F4, which is wound into substantially a cylindrical shape around the outer periphery of the former 5, from each side of the former 5. - Further, as illustrated in
FIG. 3(A) andFIG. 3(B) , a vertical sealing feed belt drivingelectric motor 66 is coupled to the left vertical sealing feed belt pulley 623 (right vertical sealing feed belt pulley 633) so as to rotationally drive the left vertical sealing feed belt 621 (right vertical sealing feed belt 631). - According to the left vertical sealing feed unit 62 (right vertical sealing feed unit 63) having the above-mentioned configuration, the left vertical sealing feed belt 621 (right vertical sealing feed belt 631) is rotationally driven at the same speed as the conveying speed of the packing film F4 while pressing, from each side of the former 5, the packing film F4 wound into substantially a cylindrical shape around the outer periphery of the former 5. Thus, the left vertical sealing feed unit 62 (right vertical sealing feed unit 63) can help (assist or guide) conveyance of the packing film F4 subjected to vertical sealing by the belt-type
vertical sealing unit 61, and can contribute to achievement of smooth feeding (conveyance) of the packing film. - In this case, description is made of the configuration having two vertical sealing feed units, that is, the left vertical
sealing feed unit 62 and the right verticalsealing feed unit 63, but the present invention is not limited thereto. The number of the vertical sealing feed units, and positions around the former 5 at which the vertical sealing feed units are to be arranged can be modified as appropriate in order to be capable of satisfactorily helping (assisting or guiding) conveyance of the packing film F4. - The packing film F5 subjected to vertical sealing and formed into substantially a cylindrical shape as described above is next subjected to lateral sealing at a portion below a content filling portion of the packing film F5. After that, the material to be packed (content) is filled in the packing film F5, and then lateral sealing is performed on a portion of the packing film F5 above the content filling portion. Thus, packing bags are linked to one another in a string form (F6).
- In this embodiment, as illustrated in
FIG. 1 andFIG. 2 , simultaneously with or immediately after lateral sealing performed by alateral sealing device 7, the fillingdevice 3 supplies, into thechute 4, a certain amount of the material to be packed contained in thehopper 2, and then fills and supplies the material to be packed from a lower end opening of thechute 4 into the packing film that is subjected to lateral sealing at the portion below the content filling portion and formed into a bag shape having an upper opening formed therein. - Further, after the above-mentioned filling of the material to be packed by the filling
device 3 is completed, under a state in whichlateral sealers 7X and 7Y sandwich the portion below the content filling portion, which is subjected to lateral sealing, thelateral sealing device 7 is moved downward by a lateral sealingdevice moving mechanism 14 by a length corresponding to one bag (one content filling portion), thereby moving downward the packing film F5 by the length corresponding to one bag. Then, thelateral sealers 7X and 7Y are laterally separated from each other to cancel sandwiching. In the separated state, thelateral sealers 7X and 7Y are returned and lifted up to original lateral sealing positions (lateral sealing positions above the content filling portion). - That is, the
lateral sealing device 7 is configured to perform lateral sealing on a portion of the packing film corresponding to a lower portion of the packing bag, and then perform lateral sealing on a portion of the packing film corresponding to an upper portion of the packing bag while moving upward and downward in synchronization with the packing film continuously conveyed at a predetermined speed. - As illustrated in
FIG. 2 , the lateral sealingdevice moving mechanism 14 includes movable pulleys (gears) 7A and 7B mounted to thelateral sealing device 7 in a rotatable manner, fixed pulleys (gears) 7C and 7D mounted to themachine body 1 in a rotatable manner, a lateralsealer driving motor 7M configured to drive and rotate the fixed pulley 7C in an up-and-down direction, and an interlockingmember 14A formed of a timing belt, a chain, or the like. The interlockingmember 14A includes both upper andlower end portions machine body 1, respectively, and an intermediate portion stretched over the upper and lowermovable pulleys - According to the lateral sealing
device moving mechanism 14 having the above-mentioned configuration, when the drivingmotor 7M rotates the fixedpulley 70 counterclockwise inFIG. 2 , thelateral sealing device 7 is moved downward due to intermeshing operation between therespective pulleys 7A to 7D and the interlockingmember 14A formed of a timing belt, a chain, or the like. Conversely, when the fixed gear 7C is rotated clockwise, thelateral sealing device 7 can be moved upward. Upward and downward movement amounts and movement positions of thelateral sealers 7X and 7Y can be adjusted so as to conform to a length dimension of one bag (see reference symbol L ofFIG. 4 ) by controlling rotation of the drivingmotor 7M. Further, upward and downward moving speed of thelateral sealers 7X and 7Y can be controlled so as to balance with feeding speed of the packingmaterial delivering device 12 and speed of feeding (conveying) the packing film F4 by thevertical sealing device 6. - In this case,
reference symbol 8 denotes an entire configuration of a cutter device arranged below the above-mentionedlateral sealing device 7. Thecutter device 8 includescutters 8A and 8B configured to cut, into upper and lower parts, a center line of the lateral sealed portion sealed by the above-mentionedlateral sealing device 7. -
FIG. 4 are views for illustrating an external appearance of a stick-like packed product F7 packed by the multiple-line automatic packing machine having the above-mentioned configuration. InFIG. 4 , reference symbol P denotes a vertical sealed portion, and reference symbol L denotes a length dimension (size) of the packed product F7. In this embodiment, it is possible to form, by sealing, stick-like packed products F7 that have various sizes and are various in the length dimension L and a filling amount. - As described above, according to the multiple-line
automatic packing machine 1 of this embodiment, a length and a size of the stick-like packed product formed in each of multiple lines, and a filling timing of the material to be packed can be changed easily and precisely. Accordingly, the present invention is suitable when the predetermined number of stick-like packed products various in size and kind are formed by heat sealing for every size, and the number of times of wasteful trial sealing performed when the size and the filling timing are changed is reduced. Thus, such economical efficiency can be obtained that a waste of the material to be packed and the packing film can be prevented. - In addition, the multiple-line
automatic packing machine 1 including the belt-typevertical sealing device 6 of this embodiment can perform vertical sealing on the packing film while continuously feeding the packing film at a predetermined speed without temporarily stopping the feeding, thereby being capable of increasing production efficiency. - Further, the multiple-line
automatic packing machine 1 including the belt-typevertical sealing device 6 of this embodiment is configured to perform vertical sealing while rotating the vertical sealing belt heated to the predetermined temperature along the conveying direction of the packing film. Accordingly, unlike the related art, when vertical sealing is performed, it is not necessary to provide the complicated advancing/retreating mechanism (reciprocating mechanism) configured to cause the vertical sealer to perform vertical sealing by moving the vertical sealer close to the packing film in the direction orthogonal to the plane of conveyance of the packing film so as to bring the vertical sealer into contact with the packing film, and then retreat the vertical sealer from the packing film. Consequently, simplification of the configuration can be promoted, and the multiple-lineautomatic packing machine 1 can contribute to reduction in vibration, noise, and the like, and to increase in conveying speed of the packing film. - That is, according to the multiple-line automatic packing machine of this embodiment, it is possible to provide the multiple-line automatic packing machine capable of, with a simple and low-cost configuration thereof, automatically packing the stick-like packed products in multiple lines while continuously feeding the packing film at a predetermined speed without temporarily stopping the feeding.
- In this embodiment, the case where a strip of the wide packing film is slit into four strips is described as an example, but the present invention is not limited thereto. The present invention is also applicable to a case where a strip of the wide packing film is slit into a plurality of strips and packing bags are automatically produced in a plurality of lines.
- Further, in this embodiment, the case where the vertical sealing belt driving motor 65 and the vertical sealing feed
belt driving motor 66 are arranged is described as an example, but the present invention is not limited thereto. The present invention maybe constructed such that the vertical sealing belt driving motor 65 and the vertical sealing feedbelt driving motor 66 are omitted, and that thevertical sealing belt 611, the left verticalsealing feed belt 621, and the right verticalsealing feed belt 631 are driven to rotate by conveyance motion of the packing film on which thevertical sealing belt 611, the left verticalsealing feed belt 621, and the right verticalsealing feed belt 631 are held in abutment. - The vertical sealing belt driving motor 65 and the vertical sealing feed
belt driving motor 66 are arranged independently of a driving source and the like configured to convey the packing film. Thus, rotation speed of thevertical sealing belt 611, the left verticalsealing feed belt 621, and the right verticalsealing feed belt 631 can be controlled independently of one another. As a result, an error and a fluctuation caused by a difference in a slip amount and the like are eliminated, thereby being capable of achieving satisfactory operation (satisfactory vertical sealing or assist to smooth conveyance of the packing film) with high accuracy in accordance with conveying speed of the packing film. - The embodiment described above is merely an example for describing the present invention. It goes without saying that various modifications may be made without departing from the gist of the present invention.
- The present invention can slit a packing film into multiple strips, and automatically produce packing bags each having four sealed sides simultaneously in multiple lines (a plurality of parallel lines) using the slit packing films. Therefore, the present invention is useful.
