Japanese Patent No. 2684335

  The apparatus disclosed in Patent Document 1 is such that cylindrical articles are fed into a cylindrical film in a state where the cylindrical articles are arranged in a line in the transport direction, and the article partitioning means positioned before and after the article transfer direction. The required number of articles are partitioned and held in group units, and transferred to a film that is formed into a cylindrical shape by a bag making machine. The article group that has been transferred to the vicinity of the downstream end of the conveyor by the supply conveyor is pushed toward the article transfer means by the horizontal movement of the pusher. The leading article pushed by the push pusher is blocked by the stopper facing the blocking position, and the aligned state is maintained. According to this apparatus, in order to supply an article to a conveyor, it is necessary to place the articles side by side in the front-rear direction, and a plurality of rows arranged in multiple rows and multiple columns in a direction intersecting the conveyance direction and in the front-rear direction. In order to package the goods in a lump, there is a problem that they must be manually arranged and supplied to the conveyor so as to be aligned in the front-rear and left-right directions. In addition, for example, the article is not fixed in individual dimensions and outer shape like frozen foods related to fried foods such as croquettes, and has an arc-shaped outer shape. In addition, the sliding resistance with the mounting surface is low and it is easy to slip. If an article is placed on a film while maintaining the alignment posture in multiple rows and multiple columns, the individual articles will slip during transportation, and the alignment state will be disturbed before being transferred from the supply conveyor to the film. In addition, since each article having an indefinite shape slides forward on the film when it is transferred to the film, the articles conveyed in an aligned manner are transferred from the conveyor to the film. This causes a problem that it is scattered back and forth and left and right, and the alignment state is disturbed. In this way, when a plurality of articles whose alignment is disturbed are placed on the film so as to be spread out from the prescribed range, the articles are collected for each package in the horizontal bag making and filling machine. There is not enough space to form a horizontal seal between the two parts, and when the horizontal seal is cut or cut in the space provided between the articles, the articles protruding into the space may bite or cause defective seals. There is.

BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic explanatory drawing of the packaging process of an Example, (a) shows the state which handed over the article | item of the top line to the film, (b) shows the state which handed over the article of the 2nd line to the film, (c) Indicates a state in which the third row of articles is delivered to the film, and (d) indicates a state in which the last row of articles is delivered to the film.

  Next, preferred embodiments of the horizontal bag making and filling machine and packaging method according to the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, the horizontal bag making and filling machine supplies articles G arranged in a direction intersecting the conveying direction (left and right direction) to the film F by a supply conveyor 10 serving as a supply means. A plurality of articles G arranged in rows and columns are configured to be collectively packaged. In the embodiment, for example, an indeterminate and slippery article G made of croquette frozen food or the like having an arcuate outer periphery is conveyed side by side in an upright posture with the arcuate peripheral edge directed vertically. As shown in FIG. 2, five articles G arranged in the left-right direction are taken as one row, and a plurality of articles G having 5 columns × 4 rows in which four rows of the articles G are arranged in the transport direction are packaged. This is illustrated as an example of batch packaging as a unit.

  As shown in FIG. 1, a supply conveyor 10 of a horizontal bag making and filling machine is provided with a feed bar (pushing member) 12 installed at a predetermined interval on a pair of endless chains that circulate by a first motor M1 as a driving means. The articles G are fed one line at a time. Further, the supply conveyor 10 includes an endless belt 14 that travels by a second motor M2 as another driving unit, and the endless belt 14 travels at the same speed as the push bar 12 or at a slightly lower speed. The articles G placed on the endless belt 14 and transported are supported by article guides 16 and 16 disposed on the left and right sides of the transport path so as to be in a standing posture along the push bar 12 and arranged in a line. In this posture, the lines are pushed line by line by the push bar 12. The articles G that are continuously conveyed line by line toward the film F that is formed by the forming unit 28 at a predetermined interval are delivered onto the film F in a posture that is aligned side by side by the push bar 12. .

  As shown in FIG. 1, detection means 20 for detecting an article G that is placed on an endless belt 14 and is pushed forward by a push bar 12 and moves forward is disposed on the side of the conveyance path in the supply conveyor 10. . The detection means 20 detects the presence or absence of the article G being supplied between the push bars 12 of the supply conveyor 10. The detection means 20 detects the presence of the article G and outputs a detection signal. The control means C of the horizontal bag making and filling machine counts the detection signal by the counting means when the article G detected by the detection means 20 is delivered from the supply conveyor 10 to the film F. The time when the article G is delivered to the film F is attached to the drive system of the push bar 12, and the current position of each push bar 12 is determined from the pulse signal oscillated from the encoder and the position where the detecting means 20 is disposed. It can be obtained from the distance to the position where G is transferred to the film F. The control means C repeats the resetting process when the count number of the counting means corresponding to the detection signal from the detection means 20 reaches the number of lines for one package. In the embodiment, according to the count number of the counting means, it can be recognized that it is the first line or the last line for one package, or an intermediate line therebetween.

  As shown in FIG. 1, the supply conveyor 10 is provided with article height detection means 22 that detects an abnormal height of the article G to be conveyed. The article height detection means 22 detects the upper end of the article G that is placed on the endless belt 14 and conveyed. For example, the article G rides on the push bar 12, and the article height detection means 22 detects the passage of the article G having a predetermined height or more. In response to the detection signal, the control means C causes a conveyance abnormality of the article G. It judges that it is a thing and stops operation | movement of a part or all of a horizontal bag making and filling machine, such as stopping the supply conveyor 10, or alert | reports by an alarm sound or an abnormal screen display. The detection means 20 and the article height detection means 22 include a photo sensor in which a light emitting part and a light receiving part are arranged opposite to the left and right of the conveyance path, and the like, which detects a change in height by area detection. Various known sensing means can be used, such as a type of sensor that can measure the height of the article.

  As shown in FIG. 1, a forming unit 28 is disposed on the downstream side of the supply conveyor 10, and a band-like film F drawn out from a raw roll 27 serving as a supply source located below is passed through the forming unit 28. Thus, the film F is formed into a cylindrical shape having a size corresponding to the placement height of the article G and the length of the plurality of articles arranged in a row. In the drawing path toward the film F forming means 28, a feeding roller 29 having a pair of nipping rollers as a film conveying means is disposed. The feeding roller 29 obtains the driving force of the third motor M3. It rotates and conveys the film F toward the upper forming means 28. The upper part of the forming means 28 is in an open state, and both end edges in the longitudinal direction along the transport direction of the film F are sandwiched by a feed roller 38 (to be described later) so as to be superposed in a palm shape. Then, the film F is formed into a cylindrical shape.

  As shown in FIGS. 1 and 2, the receiving means for the film F in the forming means 28 is provided with a restricting means 30 that can restrict the movement of the top row of articles G supplied to the film F forward in the conveying direction. Arranged. The restricting means 30 includes a number of restricting members 32 that are one less than the number of rows of articles G for one package, spaced apart from each other by the length of the front and rear of the articles G in one line above the forming means 28. 32 is between a restriction position that restricts the forward movement of the article G placed on the film F by the advance / retreat cylinder 34 and a retreat position that allows the article G to move forward from the restriction position and allow the article G to advance. Move up and down. Then, the regulating means 30 is positioned at a position to stop the article G in the leading row that is placed on the film F that is transported according to the front and back length (article length) of one line of the article G, and moves forward. It is possible to regulate the forward movement of the article G in the row by the preceding run. In the embodiment, the first regulating member 32A is disposed in front of the article G at the position where the first article G for one package is delivered to the film F so as to face the position where the first regulating member 32A can be regulated. The second restricting member 32B and the third restricting member 32C are sequentially arranged at intervals of one row from the restricting member 32A to the front in the transport direction. In the restricting means 30, the advance / retreat cylinder 34 is operated and controlled so as to move the restricting members 32 up and down in accordance with the count number of the counting means. That is, if the count number of the articles G transferred from the supply conveyor 10 to the film F is the n-th line other than the last line, the regulating means 30 is n lines forward from the start of receiving the articles G in the conveyance direction. The movement of the article G in the first row is always restricted by lowering the regulating member 32 at a position separated by the article length and moving the other regulating member 32 to the retracted position. Further, if the article G delivered from the supply conveyor 10 to the film F is the last line, the regulating means 30 retreats all the regulating members 32 from the regulated position and allows the article G to pass.

  As shown in FIG. 1, on the downstream side of the forming means 28, a transfer conveyor 36 for placing and transporting an article G supplied in a film F formed into a cylindrical shape is disposed. Further, on the upper side of the transfer conveyor 36 on the downstream side of the forming means 28, the film F stacked in a palm-like shape is fed as a film conveying means for conveying the overlapping edge portion between a pair of rollers and conveying it downstream. A roller 38 is provided. The transfer conveyor 36 and the feed roller 38 are controlled to operate synchronously with the speed set to the same speed as the transport speed of the film F. The conveying operation of the film F is controlled in accordance with the time when the article G reaches the position where the article G is delivered to the film F according to the detection result of the presence or absence of the article G in the detection means 20. The timing for delivering the article G to the film F can be obtained by a pulse signal input from the encoder with respect to the current position of the push bar 12 in the supply conveyor 10. That is, each time the article G arrives at the position where the article G is delivered to the film F until the count value of the article G detected by the detection means 20 reaches the number of lines of the article G for one package, it corresponds to one line of products. When the film F having a length to be conveyed is transported and the detection result is a shortage, the film is at a time when the push bar 12 corresponding to the shortage reaches a position where the article G is delivered to the film F. It is controlled by the control means C so that the conveyance is paused. In other words, the film conveying means composed of the feeding roller 29 and the feeding roller 38 is a length corresponding to the article length of one line until the count number of the counting means matches the number of lines of the article G for one package. The articles G placed on the film F are conveyed by the length of one line forward in the conveying direction by intermittently conveying the film F and running the transfer conveyor 36 that operates synchronously with the film conveying means. Advance. When the count number matches the value corresponding to the number of rows of articles G for one package, the remaining length of film F required for the packaging length of the article G for one package is intermittently applied. Is controlled by the control means C. That is, when the count number matches the value corresponding to the number of rows of articles G for one package, the entire length of the film F for one package is transported corresponding to the articles G of a plurality of rows that have already been transferred to the film F. The film length corresponding to the remaining length ("film length for one package"-"number of lines of articles G for one package" x "front and back length of articles G for one line) The length of the film F is controlled by the control means C so as to be conveyed by the film conveying means 29 and 38 at a time. In addition, the conveyance speed of the film F is set to be lower than at least the article conveyance speed of the supply conveyor 10, and the degree thereof may be appropriately determined according to conditions such as the conveyance interval of the article G. For example, the intermittent conveyance speed of all the films F from the first line to the last line is set to a constant speed, or only the film speed during the film conveyance corresponding to the last line is higher than the intermittent conveyance speed of the preceding line. The film conveyance speed can be changed and set as appropriate according to the packaging conditions such as shifting the speed. Moreover, it can replace with such intermittent conveyance control of the film F, and can also make a film conveyance operation into a continuous conveyance state in packaging conditions, such as a packaging speed and an article supply interval. In such a continuous conveyance operation of the film F, at least the film feeding speed with respect to the preceding row up to the last row of articles G is higher than the speed during the remaining film conveyance with respect to the last row of articles G. Should be set to.

  On the downstream side of the feed roller 38, there is disposed a vertical sealing means 40 for performing a vertical seal on the overlapping edge obtained by superimposing both longitudinal edges of the film F in the longitudinal direction. The vertical sealing means 40 is controlled by a servo motor (not shown) connected to, for example, a pair of sealing rollers, and heats the film F to a predetermined temperature by sandwiching and rotating the film F with the sealing roller. Apply a vertical seal. On the downstream side of the vertical sealing means 40, a horizontal sealing means 42 is provided which sandwiches the film F subjected to vertical sealing between a pair of sealing bodies 44, 44 and applies a horizontal sealing in a direction crossing the conveying direction of the film F. Is done. The horizontal sealing means 42 is configured to control the sealing bodies 44, 44 at a predetermined timing and a predetermined operating speed by a servo motor (not shown). The cylindrical film F is laterally sealed by sandwiching the cylindrical film F and moving in the conveyance direction of the film F between articles supplied in a plurality of columns and multiple rows, and the sealing body 44. Drive control is performed by the control means C so that the tubular film F is divided by a knife (not shown) installed in one of the two. On the downstream side of the transfer conveyor 36, crossover conveyors 46 are disposed on the upstream side and the downstream side in the position where the film F is sandwiched by the sealing bodies 44, 44, and are placed via the tubular film F. The product G was controlled by a motor (not shown) so as to travel in synchronism with the speed of the transfer conveyor 36 so as to convey the article G downstream, and obtained by dividing the tubular film F by the crossover conveyor 46 on the downstream side. Remove the pillow package as a package.

  Next, a packaging method according to an embodiment using the above-described horizontal bag making and filling machine will be described. The articles G placed on the endless belt 14 of the supply conveyor 10 are fed by the push bar 12 and are continuously conveyed side by side in the conveyance direction in a line by a plurality. The article G is detected by the detection means 20 while being conveyed by the supply conveyor 10, and based on the detection by the detection means 20, the counting means counts the number of times the article is present when the article G is delivered from the supply conveyor 10 to the film F. Count until the number of lines for one package is met. The film is fed by the feeding roller 29 and the feed roller 38 so that the film F is transported at a speed lower than the feeding speed of the articles G in accordance with the delivery timing of the articles G of each row fed from the supply conveyor 10 by the push bar 12 to the films F. F is intermittently conveyed, and the length corresponding to the length of the front and rear of the article G for one line is matched with the time when one line of the articles G for one package is placed on the film F. As the film F is conveyed, the article G transferred from the supply conveyor 10 to the film F moves forward by a distance corresponding to the length of the article G for one line as the film F is fed for one line.

  As shown in FIG. 3A, when the articles G are transferred from the supply conveyor 10 to the film F in units of lines until the number of lines for one package is reached, the film conveying means 29 , 38 transports the film F having a length corresponding to the front and rear lengths of the article G in the first row, and temporarily stops in accordance with the time when the article G is delivered to the film F by the supply conveyor 10. At that time, the first-row article G delivered to the film F is placed on the film F and moved forward by the traveling of the transfer conveyor 36. Further, the first restricting member 32A is located at the restricting position, and the other restricting members 32B and 32C are held at the retracted position, so that the top row of the article G is transferred to the film F and is slid on the film F. Then, the movement is restricted by the first restricting member 32A so as not to run ahead beyond the distance of the film conveyance length corresponding to the longitudinal length of the article G in the first row.

  As shown in FIGS. 3B and 3C, when the articles G in each row up to the number of lines for one package are transferred from the supply conveyor 10 to the film F, the articles G related to the supply have the final line. In the case of the second and subsequent lines, the film transport means 29 and 38 transport the film F for a length corresponding to the longitudinal length of the article G corresponding to each of the second and subsequent lines, as in the first line. In addition, by stopping the transfer conveyor 36 after synchronously traveling, the articles G in the preceding row placed on the film F move forward, and the articles G in the subsequent row delivered to the film F are moved forward. They are placed on the rear side of the articles G in the preceding row with a small gap therebetween. Further, when the articles G in the second and subsequent rows are transferred to the film F, the regulating member 32 corresponding to a predetermined row such as the second regulating member 32B or the third regulating member 32C is moved to the regulated position. Then, the other regulating member 32 is moved to the retracted position. In this way, since the forward movement of the article G in the first row is restricted, when the article G in the subsequent row is transferred to the film F, the article G in the subsequent row slides and is pushed from behind. In this case, the succeeding article G does not spill over to the forward displacement of the leading row that is restricted by contact with the preceding article G, and the front part of the article G for one package is the front side. Can be prevented from being displaced.

  As shown in FIG. 3 (d), when the articles G in the last row for one package are transferred from the supply conveyor 10 to the film F, the packaging length of one package is required by the film conveying means 29 and 38. As the remaining length of the film F is intermittently conveyed, a gap is placed on the rear side of the article G in the preceding row (the third row in the embodiment) delivered to the film F first. The articles G in the last row are transferred from the supply conveyor 10 to the film F, and the articles G for one package (for four rows in the embodiment) are placed on the film F in a state of being arranged in a plurality of rows and a plurality of rows. The film F is temporarily stopped after a space is provided between the last line for one package and the first line for the next one package to provide a horizontal seal. Further, when the article G in the last row is delivered to the film F, all the regulating members 32 are held at the retracted position, and the article G in which all the rows for one package are arranged is allowed to pass. The restricting means 30 moves the restricting member 32 up and down by the advance / retreat cylinder 34 before the article G is delivered to the film F, and immediately before the article G in the subsequent row excluding the top row is delivered to the film F. The top row of articles G is supported by the regulating member 32. In this way, a plurality of articles G are aligned in a plurality of rows and a plurality of columns by intermittently transporting the film F according to the length of each row for one package in accordance with the delivery timing of the articles G to the film F. Can be arranged on the film F in a state, and the aligned articles are allowed at predetermined intervals at predetermined positions with respect to the film F according to the packaging length, and for each of the articles G in a plurality of rows and columns. It can arrange | position as a state arrange | positioned in the range of length. Then, a vertical seal is applied to the overlapping edge portion of the film F formed into a cylindrical shape by the forming means 28 by the vertical seal means 40, and one package is provided by the horizontal seal means 42 disposed downstream of the vertical seal means 40. By performing horizontal sealing and cutting at an intermediate position in the space where adjacent articles G are adjacent, a pillow packaged product in which a plurality of articles G arranged in a plurality of rows and columns is collectively packaged can be obtained.

  In this way, the articles G that are divided and fed from the supply conveyor 10 for each row are arranged together on the film F in one package, so that the articles G are conveyed on the supply conveyor 10 or the film F from the supply conveyor 10. At the time of delivery of the article G to the article, for example, even if the article G has a remarkably small frictional resistance with the placing surface such as frozen food, the posture of the article G lined up in the front and rear rows due to the sliding of the article G Changes such as disturbances, clogging between rows, or excessive clogging are unlikely to occur, and the articles G placed on the film F can be in a good alignment state. In addition, when delivering from the supply conveyor 10 to the film F, one row of articles G can be placed and positioned on the film F in a state of being aligned side by side and arranged in a plurality of rows and a plurality of columns. For example, when the article G is manually placed on the supply conveyor 10, even when the article G is placed in an irregular manner for each row, the article G is not transferred when it is conveyed on the supply conveyor 10 and when it is transferred to the film F. It can be placed side by side on the film F. In this way, in the horizontal bag making and filling machine, it is possible to prevent the biting of the article G at the time of horizontal sealing due to the positional deviation and disorder of the alignment state of the article G placed on the film F, The disorder | damage | failure of the alignment state of the articles | goods G arranged in multiple rows and multiple columns can be suppressed, and the package of the several articles | goods G can be comprised favorably. In addition, when the article G is placed on the film F, the movement of the article G in the first row is restricted by the regulating means 30, so that the article G in the first row can be aligned on the left and right, It is possible to prevent the leading portion of the next article G from running ahead of the conveyance length of the film F, and to properly align the articles G in the subsequent rows by restricting the movement of the articles G in the preceding row. For example, when the article G is transported or placed on the film F in a disk shape or a spherical shape such as an article G having a remarkably low frictional resistance with a placing surface such as frozen food, or a variety of foods such as hampen, chikuwa and other foods. Even if the article G has a property that is particularly likely to be misaligned, it can be positioned at an appropriate position on the film F by the movement restriction by the restriction means 30. Since the supply conveyor 10 is configured to push the articles G divided into line units in one package by the push bar 12 and deliver them to the film F, for example, the articles G are manually placed on the supply conveyor 10. In this case, even when the articles G are placed unevenly in each line, the articles G in one line can be transported to the left and right, and the disturbance of the alignment state is also suppressed when the articles G are transferred from the supply conveyor 10 to the film F. The articles G in a plurality of rows and a plurality of columns can be put together and placed on the film F in a more organized state. Thus, when the articles G are manually supplied to the supply conveyor 10, there is no need to supply the articles G in a line-by-line arrangement, and the articles G in an irregular line are used with the travel position of each push bar 12 as a guide. Since the articles G can be aligned side by side in the conveying process from the supply conveyor 10 to the delivery position to the film F, the work load when supplying the articles G can be reduced and the supply can be reduced. Speed can be increased.

  The article G conveyed by the supply conveyor 10 is detected by the article height detection means 22 and judged to be abnormal when the conveying posture is disturbed such as riding on the push bar 12 and exceeds the allowable packaging height. In this way, the article height detecting means 22 can discriminate the article G whose conveying posture on the supply conveyor 10 is disturbed, and the supply conveyor 10 is stopped or an abnormality is notified according to the determination result. It is possible to avoid the article G having a height exceeding the allowable value from being transferred into the film.

The present invention is not limited to the configuration of the embodiment, and can be modified as follows, for example. Further, not limited to the following modification examples, various embodiments may be adopted for the configurations described in the examples within the scope of the gist of the present invention.
(1) In the embodiment, the explanation was made in the case of a horizontal bag making and filling machine in which the longitudinal end edges of the film are superposed at the upper side and the vertical seal is applied. The present invention can also be applied to a method of applying a seal, or a four-side seal type in which both longitudinal end edges of two films are superposed to perform a vertical seal, and other various horizontal bag making and filling machines.
(2) When transferring the last line of articles for one package from the supply means to the film, the film conveying means conveys the remaining length of film required for the packaging length of one package and stops it. However, when the film is transported between the last line for one package and the article on the first line for the next package, the remaining length of film may be transported in a predetermined ratio. For example, the transport length of the film accompanying the delivery of the last line of goods to the film is “length corresponding to the last line of goods” + “remaining film length for one package × 1/2 length” , Before the time when the first line of the next package of articles is placed on the film, each film should be sent so that the remaining length within the film length of one package will be sent separately. You may control so that it may convey intermittently. That is, when the count by the counting means by the detection by the detecting means reaches the last line for one package, the remaining length of the film length for one package is transported to the last line. When a space is provided between an article and the first line of the next package, the film is transported at the delivery time of the last line of at least one package, and the film is transported after the delivery time. In other words, the film conveyance may be shared so that the remaining film length for one package is obtained before the first line of the next package is delivered. Thereby, it is possible to satisfactorily package while appropriately forming a space necessary for applying a horizontal seal between the last line of articles for one package and the first line of articles for the next package. .
(3 ) As the supply means, the conveyance of the article is assisted by the endless belt in the supply conveyor, but the article placed on the bed may be pushed by a pushing member such as a pushing bar. Other configurations, such as a configuration in which an article is mounted on a mounting table such as a plate moved by a chain and transported, can also be employed. In addition, when transporting articles that are easy to roll, such as circular shapes or spherical shapes, and slippery articles, and other articles whose posture is easily changed during transportation, a depression or the like that matches the article is formed on the mounting table. Or you may make it provide the suitable support means which a conveyance attitude | position does not change, such as providing the protrusion which can support an article | item in a mounting base.
( 4 ) The supply means is not limited to one configured as one supply conveyor as in the embodiment, and the structure for delivering articles to the film via a transfer conveyor provided between the supply conveyor and the forming means, etc. You may comprise by several conveyors.
( 5 ) The restricting means may be any means that is adopted as necessary. In addition, at least various configurations that can regulate the leading article that moves in units of rows delivered from the supply means to the film can be adopted. In addition, the restricting member is not limited to a configuration that reciprocates between the restricting position and the retracted position, but may be configured to be positioned at the restricting position and the retracted position as the endless loop-shaped cord body travels. A configuration may be employed. As in the embodiment, with respect to a configuration in which a plurality of restricting members are arranged at fixed positions corresponding to each stop position with respect to a plurality of stop positions of the top row of articles, A configuration in which one regulated member is moved in the transport direction, or a regulating member is provided in units of a single row or a plurality of rows, and further, all rows or a plurality of rows for one package with the plurality of regulating members. Various configurations such as a configuration in which the regulating member provided in units is positioned at the regulating position and moved forward can be employed. Further, the regulating member can be set to an appropriate moving direction that does not interfere with other films, such as a method of moving in the left-right direction, depending on the opening position of the forming means when the film is formed into a cylindrical shape.
( 6 ) As the horizontal sealing means, regardless of the configuration of the embodiment, for example, a rotational sealing method using a pair of seal bars, and other various sealing methods applicable to other horizontal bag making and filling machines can be adopted.
