Description

  The present invention relates to a bag package discharge control method for discharging a bag package in which defective products are continuously discharged from a packaged bag discharge unit when defective products are continuously generated in bag-filling and packaging. The present invention also relates to a bag making and packaging machine that performs continuous package discharge control.

  Conventionally, vertical or horizontal automatic bag-filling and packaging machines have been put to practical use in which bags are continuously manufactured from belt-shaped packaging materials, and the bags are filled with packages to produce bag packages one after another. ing. An example of such an automatic bag making and filling machine is shown in FIG. FIG. 4 is a perspective view showing an example of a packaging machine called a horizontal automatic bag making and filling machine. In the horizontal bag making and packaging machine 50, the number of belt-like packaging materials Fw fed out from the raw roll portion Fr is several. It is guided by the rotatable guide roll 51 and is sent to a cylinder making machine (former) 52 arranged in a horizontal manner in the downstream direction of the drawer, and both side edges in the width direction approach the cylinder making machine 52. It is bent into a substantially cylindrical shape. The packaging material bent into a substantially cylindrical shape is then subjected to center sealing by a center seal (vertical sealing) device 53 on both side edges that overlap each other, and bonded to form a cylindrical packaging material Ft. The package B conveyed in the lateral direction is sequentially charged, filled, or fed into the cylindrical packaging material Ft in the cylinder making device 52. Between the package B and the package B that move back and forth, that is, at a position where the package B is sandwiched before and after the feeding direction of the cylindrical packaging material Ft, the cylindrical packaging material Ft is end-sealed in the transverse direction (lateral seal). The end seal is applied by the device 54, and the cylindrical packaging material Ft is adjusted to a position in the end seal (for example, an intermediate position in the horizontal seal) by, for example, a cutter device 55 incorporated in the end seal device 54. Is cut in the direction crossing the bag, the bag package P in which the package B is filled is manufactured.

  In the horizontal bag making and packaging machine 50, as a paper feeding device 59, a pinch roller 59a that feeds the belt-like packaging material Fw and a cylindrical packaging material Ft are overlapped at positions before and after the feeding direction of the cylinder making device 52. A paper feed roller 59b that feeds the edge portion is provided. Further, the center seal device 53 is a heating bar heater unit 56 that heats both side edges of the strip-shaped packaging material Fw that passes through the gap between the paper feed roller 59b and the end seal device 54 sequentially from the upstream side. A pressure roller portion 57 that performs center sealing by crimping both side edges of the heated belt-shaped packaging material Fw, and a circumferential groove such as a seal is formed on the circumferential surface so as to be able to mesh with each other; A pair of weighting rollers rotated at a speed synchronized with each other in opposite directions are provided, and both side edges of the cylindrical packaging material Ft subjected to heat sealing are sandwiched between the peripheral surfaces of the weighting rollers. A weighting roller portion 58 that seals the portion is provided. Moreover, the printing apparatus 60 for printing the information regarding a package on a strip | belt-shaped packaging material is provided.

  FIG. 5 is a diagram showing an example of the box motion trajectory of the upper and lower end sealers of the end seal device used in the horizontal bag making filling and packaging machine. 4 and 5, the end seal device 54 includes an upper end sealer 61a and a lower end sealer 61b each having a pair of heater blocks facing each other up and down across the transfer path of the cylindrical packaging material Ft. Both end sealers 61a and 61b are in the transfer direction at the same speed as the transfer speed of the tubular packaging material Ft with the tubular packaging material Ft sandwiched between the end sealers 61a and 61b. While moving in the (horizontal direction), end sealing is performed on the cylindrical packaging material Ft by heat sealing, and the cutter device 55 built in the upper end sealer 61a is protruded toward the lower end sealer 61b to end seal portion Se. Then, the cutter device 55 is retracted and retracted away from each other while the cutter device 55 is pulled in, and the revolving motion of moving horizontally in contact with each other is repeated. A system of the end seal device in which the end sealers 61a and 61b move like the trajectories 62a and 62b is referred to as a box motion system (for example, refer to paragraphs [0002] to [0003] of Japanese Patent Application Laid-Open No. 2006-31470).

  In the pair of upper and lower end sealers 61a and 61b, the upper end sealer 61a is provided with a through hole 64 for accommodating the cutter device 55, and the lower end sealer 61b is penetrated to receive the protruding cutter device 55. A hole 65 is provided. The cutter device 55 built in the upper end sealer 61a is projected and retracted by an actuator such as a mechanical drive mechanism and an air cylinder located above the upper end sealer 61a. It is drawn in when it is not. Further, the end sealers 61a and 61b are provided with a heater for heating inside them, although not shown, in order to heat seal the film.

  An example of another form of bag making and filling automatic packaging machine is shown in FIG. FIG. 6 is a perspective view showing an example of a packaging machine called a vertical automatic bag making filling and packaging machine, and the vertical bag making filling packaging machine 70 is the case of the horizontal bag making filling packaging machine 50 shown in FIG. Compared to the above, the center seal and the end seal are performed while the band-shaped packaging material Fw is sent in the horizontal direction, and the filling and feeding of the package are performed, whereas the band-shaped packaging material Fw is sent in the vertical direction. The form is greatly different in that the center seal and the end seal are performed and the package is filled. In brief, in the vertical bag making and filling machine 70, the belt-like packaging material Fw fed out from the raw roll portion Fr is supplied to a cylinder making device (former) 72 through several guide rollers 71 and a tension applying mechanism 80. Is done. As in the case of the horizontal bag making filling and packaging machine 50, the printing device 60 performs necessary printing on the strip-shaped packaging material Fw that is being supplied. In addition, marks such as registration marks on the packaging material are read by the sensor, and the packaging material is supplied to the cylinder making device 72 at the timing of forming the bag and filling the product into the bag.

  In the vertical bag making and filling machine 70, an input cylinder 77 for introducing and guiding a product into a cylinder making device 72 is disposed so as to penetrate therethrough, and an upper portion of the input cylinder 77 is a hopper 78 having an enlarged cross section. . The packaging material bent into a substantially cylindrical shape by the cylinder-making device 72 is guided so as to surround the charging cylinder 77, and is lowered by a paper feeding mechanism 79 by belt feeding which operates in a pair of left and right synchronously. Paper is intermittently fed to The packaging material bent into a substantially cylindrical shape is heat-sealed between the side edge portions by the center seal device 73 while the intermittent operation is stopped, while being moved downward around the charging cylinder 77, Molded into a packaging material Ft. The center seal device 73 includes a pair of heat seal bars 73a and 73b that heat-seal the edges of the packaging material.

  The cylindrical packaging material Ft is sent downward from the lower end of the input cylinder 77. The cylindrical packaging material Ft charged and filled with the product forms an end seal portion Se including a top seal portion of a bag and a bottom seal portion of the next bag by an end seal device 74 made of a heat sealer. The packaging material is sequentially supplied intermittently, and the bag package P in which the package (product) is packaged is continuously manufactured. One end sealer 74a of the end seal device 74 includes a cutter device 75, and a groove 76 into which the cutter device 75 can enter is formed in the other end sealer 74b on the other side. The cutter device 75 cuts the end seal portion Se in the lateral direction, and cuts the bag package P from the cylindrical packaging material Ft. In this vertical type bag making filling and packaging machine, the cutter device 75 is incorporated and arranged in the end seal device 74, but may be arranged separately on the downstream side of the end seal device 74. Is clear. The same applies to a horizontal type bag making and filling machine.

  By the way, on the surface of the packaging bag which wraps the package, a display unit for displaying packaging data such as the date of manufacture and the content of the package is marked at a predetermined position. The display unit is a belt-shaped package formed by the printing device 60 disposed on the travel line of the belt-shaped packaging material Fw in the horizontal or vertical bag-filling and packaging machines 50 and 70 having sealing means for sealing the packaging bag. The material Fw is stamped. In particular, when the package is a food product, the date and the type and amount of raw materials for production are one of important information sources that influence the purchase of consumers. Such printing is usually applied by a printing device 60 incorporated in an automatic packaging machine. However, the printing device 60 is broken or the tape (also referred to as an ink ribbon) is cut off, or the bag body is not printed due to an operator's work mistake or the like, or even if it is printed, it is inaccurate or unclear. Sometimes. If such printing is not performed or printing is inaccurate and unclear, the consumer may be anxious about the product and may cause distrust to the manufacturer.

  Therefore, in order to solve such a problem, a horizontal or vertical bag making filling and packaging machine has a print inspection device that automatically inspects a required printing state such as the expiration date for each bag (for example, JP 2011-037447) is often provided. Bags or bag packages that have been determined to be defective by such a printing inspection apparatus are subjected to out-of-system discharge processing as defective packaging. The out-of-system discharge processing is normally distributed from a normal product conveyance line by a distribution device arranged downstream of the bag making filling and packaging machine (for example, paragraph [0053] of JP-A-2006-290374).

  A specific example of the distribution apparatus is shown in FIG. FIG. 7 is a perspective view showing an example of a sorting device using an air jet nozzle, and an air jet nozzle 91 is disposed in the vicinity of the side of the transfer conveyor 90 where the bag package is carried out of the bag making filling and packaging machine. Has been. When information indicating that the printing is good is provided to the control device (not shown) from the print inspection device, the control device sends a good product Pok as a well-printed bag package to the air jet on the conveyor 90. Even if it passes in front of the nozzle 91, no air jet is ejected. Therefore, as shown in FIG. 7A, the non-defective product Pok is sequentially carried out by the transport conveyor 90. On the other hand, when information indicating that the printing is defective from the printing inspection device is provided to the control device, the control device indicates that the defective product Png as a bag package with poor printing is shown in FIG. 7B. The air jet Aj is ejected from the air jet nozzle 91 when it is transported on the transport conveyor 90 and passes in front of the air jet nozzle 91. Therefore, the defective product Png is blown off by the air jet Aj and discharged, and only the non-defective product Pok is carried out by the transfer conveyor 90.

  Another specific example of the sorting apparatus is shown in FIG. FIG. 8 is a perspective view showing an example of a sorting device using flippers, and a lever-like flipper 92 adjacent to the transport conveyor 90 on the side of the transport conveyor 90 where the bag package is carried out of the bag making filling and packaging machine. Is arranged. Even if the non-defective product Pok passes in front of the flipper 92 on the transport conveyor 90, the flipper 92 is not operated as shown in FIG. When the defective product Png is transported on the transport conveyor 90 together with the non-defective product Pok, as shown in FIG. 8B, the flipper 92 is activated in response to the arrival of the defective product Png. Accordingly, the defective product Png is discharged by being kicked out of the transport conveyor 90, and only the non-defective product Pok is carried out by the transport conveyor 90. Since the operation of the control device is the same as that of the air jet nozzle 91, the description thereof is omitted.

  In addition to defective date printing on the packaging material described above, the cause of occurrence of defective products Png of the bag packaging body is detection of the joint tape of the packaging material as disclosed in Patent Document 6, and the product on the seal portion. For example, there is a waste bite detection (for example, Japanese Patent Application Laid-Open No. 2007-302341). In order to clearly distinguish such defective packaging products from non-defective products, for example, as disclosed in Patent Document 1, after performing a horizontal seal, it may be discharged in a continuous state without cutting. is there. The discharge of the defective packaging in the continuous packaging state is shown in FIG. FIG. 9 is a view for explaining continuous discharge when the discharge means is the air jet nozzle 91. The defective product Png is separated from the next non-defective product Pok produced by the end seal device 54 (in the case of a horizontal bag making filling and packaging machine) or 74 (in the case of a vertical bag making filling and packaging machine) by the cutter devices 55 and 75. Without being discharged, it is discharged in a continuous PS state at the end seal portion Se. By blowing out the air jet Aj from the air jet nozzle 91, the continuous package PS is discharged from the conveyor 90 to the side, so that the distinction between the defective product Png and the normal product Pok becomes clear, and the defective product Png. Can be prevented from being unintentionally carried out together with the non-defective product Pok by the transfer conveyor 90.

  By the way, when the automatic bag making filling and packaging machine performs continuous packaging discharge of defective packaging as described above, distinction from normal products becomes clear, and defective products are not mistakenly recognized as non-defective products, The advantage is obtained. However, multiple factors that cause defective packaging such as detection of film splicing tape, biting of product residue into the seal, or faint printing due to defective date printing tape occur continuously. There is. In such a case, a defective packaging product having a large number of continuously connected bag packages, that is, a long continuous PS is generated and transported onto the transport means. The long continuous PS may not be normally discharged by the sorting device arranged on the transport means, and may hinder the transfer of non-defective products. Further, when the distance between the automatic packaging machine and the sorting device is short, if a long continuous PS is generated, the continuous PS may be twisted by the operation of the sorting device, and the end seal may be adversely affected.

  FIG. 10 and FIG. 11 show how the long continuous PS is not normally discharged in the sorting device. FIG. 10 shows that the distribution device (in this example, the air jet nozzle 91) tries to blow the long continuous package PS out of the transport conveyor 90, but cannot be completely discharged from the transport conveyor 90 because it cannot be completely blown off. A state in which the conveyance of the subsequent non-defective product Pok is obstructed is shown. Further, FIG. 11 shows that the long continuous package PSng is twisted by the operation of the sorting device (air jet nozzle 91 for injecting the air jet Aj), and the end seal device 54 and the cutter device 55 are in contact with the cylindrical packaging material Ft. The normal end seal and cutting cannot be performed. As described above, when the long continuous package PSng cannot be normally discharged, the continuous package PSng is clogged in the bag packaging body discharge portion of the bag making filling and packaging machine, or is disposed downstream thereof (for example, A defect that adversely affects a non-defective bag packaging body collecting device, a boxing device for cardboard boxes, and the like. And after stopping the bag making filling and packaging machine and the post-processing device and removing the long continuous packing PSng on it, setting and setting of the packaging material, bag making filling packaging machine and the post-processing device are done again, and after the confirmation A troublesome and inefficient measure of restarting the operation of the bag making and filling and packaging machine and the post-processing apparatus is required.

According to Patent Document 1, in response to detection of an excessively light article or a foreign metal, the corresponding bag is handled as an abnormally packaged product. For example, cutting into individual bags is stopped at the time of horizontal sealing. Then, when collecting the abnormally packed product in a continuous packaging state in which the bags are continuous up and down, a delivery mechanism for delivering the obtained bags to the downstream side, and without reversing the received posture, the bags are moved to the downstream side. The structure that can switch between the delivery operation and the operation to deliver the bag downstream by reversing the received posture makes it easy to distinguish abnormally packaged bags and normal packaged bags in appearance. There has been proposed a bag making and packaging machine that can be transferred to the downstream side and that can be smoothly transferred to the downstream side even when the bag is manufactured in a bundled state.
Further, in Patent Document 2, a carry-out chute located directly under the horizontal sealer is provided, and by changing the angle of the carry-out chute by driving a motor, any type of defective product can be used as a good product carry-out conveyor or a defective product carry-out conveyor. There has been proposed a vertical bag making and filling package including a discharge device that can reliably discharge out of the system by sorting and guiding.
Further, Patent Document 3 discloses that in an integrated packaging system in which a plurality of articles supplied from the upstream side are received and stacked, and then packed on the downstream side, the stacking device and the packing device are each modularized, and a connecting portion between both devices is provided. Easily build a system that can handle the form of goods, the integrated form, the packing form, etc., even when one of them is exchanged with another specification by adopting a configuration that allows the exchange of goods and electrical signals even when the other party is exchanged Therefore, there is no need to switch the system including the stacking device and the packing device to a completely different one, and an integrated packing system for articles that can be switched with a minimum investment is proposed.

In Patent Document 4, a packaging machine and a print inspection apparatus are connected and connected via a conveying means, so that a unit body (a photographic camera is separated from the packaging machine) with respect to a packaging machine, particularly an existing packaging machine. It is possible to attach a print inspection apparatus configured to include a print inspection apparatus, and a print inspection apparatus capable of determining the quality of a print state printed by a packaging machine using the print inspection apparatus has been proposed.
Further, in Patent Document 5, an operation unit for operating a printing machine and an inspection machine, and a display unit for integrating and displaying the printing information of the printing machine and the inspection information of the inspection machine are provided on one screen for printing. By operating and confirming the machine, and operating and confirming the inspection machine, various printing information, for example, the date of production and the expiration date, and the inspection of the printed contents can be performed quickly and accurately. There has been proposed a print inspection system that can be performed in a short time.
Further, in Patent Document 6, filling is performed by detecting a film seam portion, treating a sachet corresponding to the seam location as a defective product, and automatically sorting and transporting the packaging bag treated as the defective product and the non-defective sachet. Broadcasters have been proposed.

  As described above, a plurality of factors are continuously generated, or even a single factor is generated over a plurality of bags, and a bag package including defective products is discharged in a continuous state. If the conditions continue to occur or if there are many settings for the number of bag packs to be discharged in a continuous packaging state, the bag pack discharge unit or the post-processing device of the bag making and packing machine Therefore, in the bag making and filling machine, there is a problem to be solved in that a bag package including only defective products or containing good products and defective products is discharged with a short number of continuous packages.

  An object of the present invention is to solve the above-described problem, and even when a bag packaging body that becomes a defective product is continuously generated, it is used in an end seal device or a downstream post-processing device of a bag making filling packaging machine. Provided a bag-filling and packaging control method for bag-filling and packaging, and a bag-making and filling and packaging machine that can discharge defective products as short continuous packages that can be clearly distinguished from non-defective products without adverse effects. It is to be.

  In order to solve the above problems, the continuous discharge control method in bag-filling and packaging according to the present invention is a method for controlling the package packaging material obtained by feeding a cylindrical packaging material obtained by molding a strip-shaped packaging material into a cylindrical shape. The cylindrical packaging material is subjected to an end seal in the transverse direction between the packages, and the bag package is continuously manufactured by sequentially repeating the filling of the package and the end seal, and a cutter device. In the bag-filling packaging that separates the produced bag package from the subsequent bag package by operating the end seal, the number of the bag packages produced as defective products continuously is reduced. In response to being expected to be 3 or more, by operating the cutter device with respect to the end seal for each basic package unit in which the bag package is continuously connected, Basic It is characterized by controlling so as to discharge the continuous wrapping of the packaging unit.

  In order to solve the above-mentioned problems, a bag-filling and packaging machine for performing continuous package discharge control according to the present invention includes a tube-making machine that bends a belt-like packaging material into a substantially cylindrical shape, and the belt-like packaging material through the tube-making machine A sheet feeding device for feeding the sheet to the longitudinal direction, a center seal device for forming a center seal on both side edges of the bent band-shaped packaging material to form a cylindrical packaging material, and the cylindrical packaging through the inside of the cylinder-making machine A package supply device for filling a package with a package, an end seal device for applying an end seal in a transverse direction between the packages on the cylindrical package material, and the bag package manufactured by operating the end seal A cutter device for separating the body from the subsequent bag package body, and the paper package for continuously producing the bag package body by sequentially repeating the filling of the package and the end seal from the center seal, In a bag-filling and packaging machine provided with a control device for controlling the operation of the device, the center seal device, the package supply device, the end seal device and the cutter device, the control device is continuously regarded as a defective product. In response to the fact that the number of the bag packages to be manufactured is expected to be 3 or more, the cutter device is attached to the end seal for each basic continuous unit in which the bag packages are continuously connected. By operating, it controls so that the said bag packaging body may be discharged | emitted as a continuous package of the said basic package unit.

  According to the continuous package discharge control method in the bag-filling and packaging and the bag-making and filling machine that performs the continuous package discharge control, the tubular packaging material obtained by forming the strip-shaped packaging material into a tubular shape is fed by paper. The inside is filled with a package, the end-sealing is performed in the transverse direction between the packages on the cylindrical packaging material, and the bag package is continuously formed by sequentially repeating the filling of the package and the end seal. A product that performs a basic continuous packaging operation in which the manufactured bag packaging body is separated from the subsequent bag packaging body by operating and operating the cutter device with respect to the end seal. In the case where the number of bag packages manufactured as a product is 3 or more and a large continuous package is expected to be discharged, the cutter device is operated with respect to the end seal for each basic package unit. As multiple It can be discharged in portions to the basic communication hull unit consisting Sokarada.

  In the continuous package discharge control method in the bag making and filling and the bag making and filling and packaging machine for performing continuous package discharge control, the basic continuous unit is formed by connecting the two bag packages into one continuous package. 2 ”. By setting the basic package unit to “2”, as a minimum-length package, a non-defective product (a normal product, which is cut individually by the operation of the cutter device), It can be distinguished from a good bag package. Further, in this case, when the number of the bag packages continuously manufactured as defective products is an even number, all the continuous packages are formed by connecting the two defective products, and the number is an odd number. In some cases, the defective package and the non-defective product can be formed by connecting either the first package or the last package. That is, when the number of consecutive defective products is an even number, all the continuous packages are formed by connecting two defective products. In addition, when the number of consecutive defective products is an odd number, the first or last continuous package is formed by connecting defective products and non-defective products, and the remaining continuous packages are all connected by two defective products. By forming it, the number of non-defective bag packaging bodies that are discharged together with defective products and are wasted can be suppressed to a minimum of one.

  In the continuous package discharge control method in this bag-filling and packaging, and the bag-making and filling machine that performs continuous package discharge control, the basic continuous unit is connected to the two bag packages to form one continuous package. It can be assumed that “2” and “3” in which the three bag wrapping bodies are connected to form one continuous package. In this case, according to the fact that the number of the bag wrapping bodies that are continuously manufactured as defective products is an even number, the continuous packing can be a continuous packing whose basic continuous unit is “2”. In addition, according to the fact that the number of bag wrapping bodies continuously manufactured as defective products is an odd number, it can be divided into an odd number “3” and an even number. For 3 defective bags, 3 continuous products with the basic unit “3” can be connected to form a continuous package. The remaining number of defective bags One or a plurality of continuous packages can be formed by connecting two defective products whose basic continuous unit is “2”. Further, in this case, either the first or the last package is one package whose basic package unit is “3”, and the other package is the basic package unit “2”. One or a plurality of continuous packages can be provided.

  In a bag making and filling and packaging machine that performs continuous package discharge control, the control device sets a basic continuous unit setting unit that sets the basic continuous unit according to a setting input from a basic continuous unit setting unit, and assumes that a defective product is generated. In response to a signal indicating that a defective product is expected to be generated from the sensor means, a defective product continuous number calculating unit that calculates the number N of defective products that will continuously occur, and Based on the basic package unit set in the basic package unit setting unit and the number of defective products calculated in the defective product continuous number calculation unit, the cutter device is driven by a cutter device driving unit that drives the cutter device. A linkage generation control unit that outputs a non-driven control signal can be provided. In the basic package unit setting unit, the basic package unit is set according to the setting input from the basic package unit setting means, and the defective product continuous number calculation unit calculates the number N of defective products that will occur continuously. Then, the continuous package generation control unit outputs a drive / non-drive control signal to the cutter device driving unit that drives the cutter device, and the cutter device performs bag packaging with respect to the end seal portion of the continuous bag packaging body. Of the normal cutting timing performed for each body, it is driven for each basic package unit to cut the corresponding end seal part, but at other cutting timings it is not driven and the end seal part is not cut.

  In the bag making filling and packaging machine for performing continuous package discharge control, the bag making filling and packaging machine can be a vertical or horizontal bag making filling and packaging machine. That is, in the case of automatic bag making and filling and packaging, the continuous package discharge control according to the present invention can be applied regardless of the type, and can be applied to both vertical and horizontal bag making and filling machines.

  Since the continuous package discharge control method and the continuous bag discharge control machine for performing continuous package discharge control according to the present invention are configured as described above, there are three or more consecutive defective bag packages. Even if they occur, defective products are always discharged in basic package units such as 2-pack units or a combination of 2-pack units and 3-pack units, which adversely affects downstream discharge devices and end seals. Without being discharged as a package that can be clearly distinguished from normal products.

  For normal operation of the bag making and filling machine, normal operation setting means 21 and operation state sensor means 22 are provided as setting inputs to the control device 1 from the outside. In the normal operation setting means 21, the number of bag packaging bodies manufactured per hour and the speed and seal temperature of each device are set according to the characteristics of the packaging material based on the number of bags, and the set information is input to the control device 1. Is done. The operating state sensor means 22 is arranged at various locations on the bag making filling and packaging machine, and for the belt-shaped packaging material, a sensor for detecting the passage of the registration mark, a sensor for detecting the passage of the package to be fed, and paper feeding And a sensor or the like for detecting the origin position in order to determine the timing of the servo motor that performs sealing. Information detected by these sensors is input to the central control unit 10 of the control device 1, and the central control unit 10 receiving the input of the information sends control signals to the device drive units 9a to 9c based on the calculation. The normal operation of the bag-filling and packaging machine is performed.

  In order to set the basic package unit to the control device 1, basic package unit setting means 23 is provided as a setting input to the control device 1 from the outside. In this example, the basic package unit setting means 23 can select “2” as the basic package unit and “2” and “3” as the basic package unit. The basic integration unit setting information selected by the basic integration unit setting means 23 is set in the basic integration unit setting unit 11 of the control device 1. The basic package unit setting unit 11 is preferably configured so that the selected basic package unit is reflected so that the selected basic package unit is activated, regardless of which is selected.

  In horizontal or vertical bag making and filling and packaging machines 50 and 70 as shown in FIGS. 4 and 6, printing disposed on the paper feed path of the strip-shaped packaging material Fw fed out from the raw roll portion Fr The paper feed path from the device 60 to the end seal devices 54 and 74 disposed downstream of the cylinder making devices 52 and 72 has a sufficiently long length. Therefore, if the printing device 60 performs printing on the belt-shaped packaging material Fw, the printing fading continuously occurs in the belt-shaped packaging material Fw from the printing device 60 to the end seal devices 54 and 74. When the number of display portions where printing blur has occurred increases to a considerable number and the end seal devices 54 and 74 are operated to produce the bag packaging body P as it is, the bag packaging body P (defective product Png) where printing blur has occurred. The number reaches a considerable number.

  As a means for detecting the occurrence of an event leading to the manufacture of a bag package that will be a defective product Png, a defective product occurrence sensor means 24 is provided. The defective product occurrence sensor means 24 is applied to the packaging material by, for example, the print detection means 25 for detecting a faint or unclear print on the strip-shaped packaging material Fw printed by the printing means 60 and the center seal device 3. The operation proceeds normally, such as when the center seal failure detection means 26 detects a failure such as a shift or flaw in the center seal, or when the bag making filling and packaging machine temporarily stops and then restarts. Including a restart operation detection means 27 for detecting the occurrence of a defective product Png caused by stopping the supply of the package B in order to observe and test whether or not It is. When these events occur, it is assumed that even if the end seal device 4 and the cutter device 5 operate normally downstream, a bag package that is a defective product Png is manufactured.

  When a signal indicating that a defective product is assumed to be generated from the defective product occurrence estimation sensor means 24 is input to the control device 1, the continuous defect number calculation unit 12 is continuously generated in response to this signal. The number of consecutive defects N is calculated as the number of defective products. The number of consecutive defects N includes information such as the time and range in which a situation where a defective product is expected to occur and the operation information of the bag making and filling machine at that time detected by the operation state sensor means 22 (particularly the operation). Information on speed).

  The control device 1 has a basic integration unit of “2” or “2” and “3” set in the basic integration unit setting unit 11 in accordance with a setting input from the basic integration unit setting means 23, Based on the number N of continuous defects calculated by the non-defective product number calculation unit 12, a continuous generation control unit 13 that outputs a drive / non-drive control signal to the cutter device drive unit 7 that drives the cutter device 5 is provided. Yes. The cutter device driving unit 7 drives and controls the cutter device 5 based on a control signal from the continuous package generation control unit 13. By this drive control, the cutter device 5 is driven for each basic package unit of the normal cutting timing performed for each bag package P with respect to the end seal portion Se of the continuous bag package, and the corresponding end seal. The part Se is cut, but at other cutting timings, it is not driven and the end seal part Se is not cut.

  The operation of the control device 1 will be described with reference to the flowchart shown in FIG. A normal packaging operation is shown in the flowchart (a) of FIG. For normal operation of the bag-filling and packaging machine, normal operation is set by the normal operation setting means 21 as a setting input from the outside to the control device 1 (step 1; hereinafter abbreviated as “S1”). the same). In the normal operation setting means 21, the number of manufactured bag packages per hour and the operating speed, seal temperature, etc. of each device are set based on the number of bag packaging bodies manufactured per time, and the information is input to the control device 1. Is done. For the belt-shaped packaging material Ft, a sensor for detecting the passage of a registration mark, a sensor for detecting the passage of a package to be fed, and a servo motor (or air actuator) 8a to 8c, 6 for operating a paper feed or a heat sealer. The driving state detected by the driving state sensor means 22 including a sensor for detecting the origin position in order to take timing is input to the central control unit 10 of the control device 1 (S2). Upon receiving these information inputs, the central control unit 10 sends control signals to the device drive units 9a to 9c and the cutter device drive unit 7 based on the calculation (S3). The device driving units 9a to 9c and the cutter device driving unit 7 drive the servo motors 8a to 8c and 6 of the devices by these control signals, whereby the devices 2 to 4 and the cutter device 5 are operated, and bag making is performed. A normal operation of the filling and packaging machine is performed (S4). It is determined whether or not the packaging is finished (it may include a stop) (S5). If not finished, the process returns to S2, and if finished, the operation of each device of the packaging machine is stopped (S6).

  The operation of the control device 1 when the basic package unit is set is shown in the flowchart (b) of FIG. First, the basic package unit is set in the basic package unit setting unit 11 of the control device 1 by the input setting in the basic package unit setting means 23 (S11). Here, the basic package unit is when “2” is set, or when “2” and “3” are set. It is determined whether or not a defective product is expected to be generated based on a signal from the defective product generation sensor 24 (S12). If the determination in S12 is No, normal packaging is performed (S13; flowchart (a); after that, it is possible to shift to an appropriate operation such as stopping the operation of the packaging machine, but details of these are also omitted) To do). If the determination in S12 is Yes, the defective product continuous number calculation unit 12 calculates the number of defective products (number of continuous defects) N that will occur continuously (S14). The number N of continuous defects is based on information such as the time and range in which an expected occurrence of defective products continues and the operation information (especially information on the operation speed) of the bag filling and packaging machine detected by the operation state sensor means 22. Calculated based on

  Based on the number N of consecutive failures, the control of continuous generation is performed (S15). When only “2” is selected and set as the basic package unit in the setting of the basic package unit in S11 (S16), the continuous bag package is a series of two bag packages connected. It is produced by cutting sequentially from the cylindrical packaging material Ft as a package. It is determined whether or not the calculated number of consecutive defects N is an even number (S17). When the number of consecutive defects N is an even number, each generated continuous package PS is a continuous package composed of a bag package as two defective products Png (S18). An example of this case is shown in FIG. 3 as the case of “the number of consecutive defects 4” and “the number of consecutive defects 6”, and each of the two two-pack PS2 in which two defective products Png are connected, It is shown as a continuous package PS2. Further, in the determination at S17, when the number of consecutive defects N is an odd number, the first or last continuous package PS is equal to the bag package as the non-defective product Pok and the bag package as the defective product Png. The tubular packaging material Ft is cut in a state of being connected one by one, but the remaining continuous packaging PS is the continuous packaging PS2 in which the bag packaging bodies made of two defective products Png are connected (S19). An example of this case is shown in FIG. 3 as “the number of consecutive defects 3”, “the number of consecutive defects 5”, and “the number of consecutive defects 7”, and the last continuous PS is the defective product Png. It is generated in a state in which each of the bag package and the bag package as the non-defective product Pok is included, and the remaining package PS is generated by connecting two defective products Png to each other. "Two continuous packages PS2", "two consecutive failures PS" and "two consecutive packages PS2". As described above, the continuous generation is performed with the contents of S18 and S19 according to whether the number of consecutive failures N is even or odd (S20). In FIG. 3, the number of consecutive defects 2 may be handled as such in the past and is shown for comparison.

  In the setting of the basic continuous unit in S11, when “2” and “3” are selected and set as the basic continuous unit (S21), whether the number of consecutive defects N is even or odd. When it is determined (S22) and the number of consecutive defects N is an even number, “2” is applied as the basic continuous unit, and the continuous PSs sequentially cut from the cylindrical packaging material Ft are all two defective products Png. It is set as the continuous package PS2 to which the bag package is connected (S23). The continuous processing in this case is the same as when the continuous defective number N is an even number (S18) when only “2” is selected and set as the basic continuous unit (S16). The generated continuous package PS is a continuous package PS2 composed of two bag packages P, all of which are defective products Png (see the cases of “number of consecutive defects 4” and “number of consecutive defects 6” shown in FIG. 3). . When the number of consecutive defects N is an odd number, the first or last continuous package PS is defined as a continuous package PS3 in which three defective products Png are connected, and the remaining continuous packages PS are all connected to two defective products Png. The package PS2 is set (S24). An example of this case is shown in FIG. 3 as the case of “the number of consecutive defects 3”, “the number of consecutive defects 5” and “the number of consecutive defects 7”, and the last continuous PS is all defective products Png. It is generated as a triple continuous package PS3 composed of a certain three bag packages P, and the remaining continuous packages PS are all two continuous packages PS2 generated by connecting two defective products Png (“number of consecutive defects 3”). In the case of "2", one double package PS2 in the case of "5 consecutive defects", and two double packages PS2 in the case of "7 consecutive defects"). As described above, the continuous generation is performed with the contents of S23 and S24 according to whether the number of consecutive defects N is an even number or an odd number (S25).

  When “2” and “3” are selected and set as the basic continuous unit, when the number of consecutive defects N is an even number, only “2” is set as the basic continuous unit, and the number of consecutive defects N is an odd number. In this case, as the basic continuous unit “2” and “3”, the continuous PS can be generated only from the defective product Png. That is, since the continuous package PS is not generated from the non-defective product Pok and the defective product Png, the non-defective product Pok is not sacrificed when the defective product Png is discharged, and the non-defective product Pok and the defective product Png are maximized. Can be sorted. In addition, when only “2” is selected as the basic continuous unit, even when all the discharged continuous PSs are not generated only from the defective product Png, the number of non-defective products Pok that are sacrificed is at most one. The efficiency with which the non-defective Pok can be shipped as a product can be extremely increased.
