Description

本発明は、供給コンベヤによって所定間隔毎に物品が供給される筒状フィルムに日付等の印刷を行う横形製袋充填機における印刷制御装置に関するものである。 The present invention relates to a printing control apparatus in a horizontal bag making and filling machine that performs printing of a date or the like on a cylindrical film to which articles are supplied at predetermined intervals by a supply conveyor.

製袋手段で帯状フィルムを筒状に成形して、その筒状フィルム中に物品を所定間隔毎に供給すると共に、該供給された物品の前後位置で筒状フィルムに横シールを施して、包装品を得る横型製袋充填機が知られている。このような横形製袋充填機には帯状フィルムをガイドローラに巻掛け案内するフィルム搬送経路が、例えば特許文献１の図１のごとく形成されており、例えば帯状フィルムを走行させる繰出しローラ近傍等のフィルム搬送経路等に図示されていない印刷装置が配設されている。このような横型製袋充填機は、起動開始の操作がなされると、繰出しローラ等によるフィルムの走行駆動と、供給コンベヤの物品供給と、筒状フィルムに横シールを施すシール手段の駆動を同期するように、夫々に配設された駆動手段を駆動制御して起動停止の操作がなされると、夫々の駆動手段が停止する。そして、印刷装置は、例えば繰出しローラを回転駆動するサーボモータ等の駆動手段に関するフィルム搬送パルスが一包装における特定位置に相当するパルスに達する毎に印刷処理を行う等、フィルム搬送パルスに基づき日付等の印刷を行う。このため、例えば、生産が終了間際になって、供給コンベヤで送り込まれる生産予定の最後の物品が製袋手段に供給された時点においては、フィルムが走行していることから、フィルム搬送パルスに基づき印刷装置から製袋手段までの間に一または二以上の包装袋分の印刷がなされている。この生産終了間際における印刷装置から製袋手段までの間の所定包装袋分の印刷は、生産予定数を超えた不要な印刷である。しかし、最終の物品をシール手段で横シールして包装袋を得るためにはその不要な印刷を防ぐことができなかった。 A belt-shaped film is formed into a cylindrical shape by bag-making means, and articles are supplied into the cylindrical film at predetermined intervals, and the cylindrical film is laterally sealed at the front and rear positions of the supplied articles, and then packaged. Horizontal bag making and filling machines for obtaining products are known. In such a horizontal bag making and filling machine, a film conveyance path for winding and guiding a belt-like film around a guide roller is formed as shown in FIG. 1 of Patent Document 1, for example, in the vicinity of a feeding roller for running the belt-like film. A printing apparatus (not shown) is disposed in the film conveyance path. In such a horizontal bag making and filling machine, when the start-up operation is performed, the driving of the film by the feeding roller and the like, the supply of the articles on the supply conveyor, and the driving of the sealing means for performing a horizontal seal on the cylindrical film are synchronized. As described above, when the start / stop operation is performed by drivingly controlling the drive means arranged in each, the respective drive means are stopped. The printing apparatus performs a printing process each time a film transport pulse related to a driving unit such as a servo motor that rotationally drives the feeding roller reaches a pulse corresponding to a specific position in one package, etc. Print. For this reason, for example, at the time when production is about to end and the last article to be produced that is fed by the supply conveyor is supplied to the bag making means, the film is running, and therefore, based on the film conveyance pulse. One or more packaging bags are printed between the printing device and the bag making means. The printing for a predetermined packaging bag between the printing device and the bag making means just before the end of production is unnecessary printing exceeding the planned production number. However, in order to obtain a packaging bag by laterally sealing the final article with a sealing means, the unnecessary printing could not be prevented.

請求項１の発明では、供給コンベヤ（８）の載置領域に、印刷フィルム待機領域に位置する印刷完了済みの包装袋分に対応した物品（９）を載置している状態で、物品検知手段（２２）が印刷完了済みの包装袋分の次の一包装袋分に対応する次の物品（９）を検知すると、該検知された一包装袋分の物品（９）に対応して帯状フィルム（６）に一包装袋分だけ印刷が施されるので、不要な印刷を行うことなく包装することができる。 In the first aspect of the invention, the article detection is performed in the state where the article (9) corresponding to the printed packaging bag located in the print film standby area is placed on the placement area of the supply conveyor (8). When the means (22) detects the next article (9) corresponding to one packaging bag next to the printed packaging bag, the strip (22) corresponds to the detected article (9) for one packaging bag. Since the film (6) is printed only for one packaging bag, it can be packaged without performing unnecessary printing.

請求項１の発明を前提とする請求項２の発明（第２〜３実施形態に対応）において、前記供給コンベヤ（８）は、筒状フィルム（７）に物品（９）を供給するよう前記フィルム搬送手段（５或いは１３，１４，２８，２９）によるフィルム走行の速度と同調して走行駆動される第一コンベヤ(２５)と、その第一コンベヤ(２５)の上流に接続された第二コンベヤ(２６)を備え、該第一コンベヤ(２５)は前記印刷完了済みの包装袋分に対応した物品（９）を載置し得る載置領域として設定され、前記第二コンベヤ(２６)上における物品検知手段（２２）により検知された前後の物品（９）の移動情報に基づき、該検知された後続の物品（９）が第一コンベヤ（２５）に乗り移るまでに、該物品（９）の前方で前記載置領域に載置された、一包装分先行した物品（９）との間隔を調整するように、第一コンベヤ（２５）と第二コンベヤ（２６）との相対的な搬送速度を変更する。請求項２の発明では、第二コンベヤ(２６)上における物品検知手段（２２）による物品（９）の検知に基づき、第一コンベヤ（２５）と第二コンベヤ（２６）との相対的な搬送速度が変更され、第一コンベヤ(２５)の載置領域に載置された、一包装分先行した物品（９）との間隔が広すぎる場合などに該間隔を調整して、物品（９）を筒状フィルム（７）中に円滑に供給することができると共に、不要な印刷を防止することができる。例えば、筒状フィルム（７）を余すことなく、一定の袋長さの包装袋が続くように、一包装袋分先行した物品（９）との間隔を調整すると共に、供給コンベヤ（８）とフィルム搬送手段（５或いは１３，１４，２８，２９）と横シール手段（４）を連係動作させることにより空袋の発生も防止し得る。 In the invention of claim 2 (corresponding to the second to third embodiments) based on the invention of claim 1, the supply conveyor (8) is configured to supply the article (9) to the tubular film (7). A first conveyor (25) driven and driven in synchronism with the film traveling speed by the film conveying means (5 or 13, 14, 28, 29), and a second conveyor connected upstream of the first conveyor (25). A conveyor (26), the first conveyor (25) is set as a placement area on which articles (9) corresponding to the printed packaging bags can be placed, and the second conveyor (26) On the basis of the movement information of the preceding and following articles (9) detected by the article detection means (22), the article (9) is moved until the detected succeeding article (9) is transferred to the first conveyor (25). Preceding one package, one package ahead The relative conveyance speed of the first conveyor (25) and the second conveyor (26) is changed so as to adjust the distance from the article (9). In the invention of claim 2, relative conveyance between the first conveyor (25) and the second conveyor (26) based on the detection of the article (9) by the article detection means (22) on the second conveyor (26). When the speed is changed and the distance between the article (9) preceding by one package placed on the placement area of the first conveyor (25) is too wide, the article (9) is adjusted by adjusting the distance. Can be smoothly supplied into the tubular film (7), and unnecessary printing can be prevented. For example, while adjusting the interval with the article (9) preceded by one packaging bag so that the packaging bag of a certain bag length continues without leaving the tubular film (7), the supply conveyor (8) By causing the film conveying means (5 or 13, 14, 28, 29) and the lateral sealing means (4) to operate in an associated manner, the occurrence of empty bags can be prevented.

請求項１または請求項２の発明を前提とする請求項３の発明（第１〜３実施形態に対応）において、前記フィルム進入ガイドローラ（１８，２９）は、フィルムを巻掛け案内するフィルム巻掛け部（１８ａ，２９ａ）を有し、前記印刷手段（１６）はフィルム巻掛け部（１８ａ，２９ａ）で帯状フィルム（６）に印刷し得るよう位置決めされている。請求項３の発明では、印刷完了済みの包装袋数を少なくすることができ、その印刷完了済みの包装袋分に対応した物品（９）を載置する供給コンベヤ（８）の載置領域を短くすることが可能となり、横形製袋充填機全体の小型化が可能になる。また、フィルム進入ガイドローラ（１８，２９）が印刷時における印刷対象物を支持する台としても兼用されるので、部品点数が少なくなる。 In the invention of claim 3 (corresponding to the first to third embodiments) based on the invention of claim 1 or claim 2, the film entry guide roller (18, 29) is a film winding for winding and guiding a film. The print means (16) is positioned so as to be able to print on the belt-like film (6) at the film winding part (18a, 29a). In the invention of claim 3, the number of packaging bags that have been printed can be reduced, and the placement area of the supply conveyor (8) on which articles (9) corresponding to the packaging bags that have been printed are placed. This makes it possible to shorten the size of the entire horizontal bag making and filling machine. Further, since the film entry guide rollers (18, 29) are also used as a table for supporting the printing object during printing, the number of parts is reduced.

請求項３の発明を前提とする請求項４の発明（第３実施形態に対応）において、前記フィルム巻掛け部（２９ａ）はフィルムを走行する前記フィルム搬送手段（５或いは１３，１４，２８，２９）におけるフィルムガイドローラ（２９）によって構成されている。請求項４の発明では、フィルム供給源（１）から製袋手段（２）までのフィルム案内経路が簡素になり、帯状フィルム（６）に対する印刷手段（１６）の干渉を減らすことができる。 In the invention of claim 4 (corresponding to the third embodiment) based on the invention of claim 3, the film winding part (29a) is the film transport means (5 or 13, 14, 28, 29) and the film guide roller (29). In the invention of claim 4, the film guide path from the film supply source (1) to the bag making means (2) is simplified, and the interference of the printing means (16) with the belt-like film (6) can be reduced.

本発明は、横形製袋充填機における印刷制御装置において不要な印刷を防止することができる。 The present invention can prevent unnecessary printing in a printing control apparatus in a horizontal bag making and filling machine.

第１実施形態に係る横形製袋充填機を示す略体図。1 is a schematic diagram showing a horizontal bag making and filling machine according to a first embodiment. 第２実施形態に係る横形製袋充填機を示す略体図。The schematic diagram which shows the horizontal bag-making filling machine which concerns on 2nd Embodiment. 第３実施形態に係る横形製袋充填機におけるフィルム案内経路を示す図。The figure which shows the film guide path | route in the horizontal bag-making filling machine which concerns on 3rd Embodiment.

図１に示す第１実施形態に係る横形製袋充填機は、フィルム供給源１から引き出した帯状フィルム６を製袋手段２で筒状に成形し、縦シール手段３でその筒状フィルム７に縦シールを施すと共に、供給コンベヤ８によって物品９を所定間隔毎に筒状フィルム７中に供給した後、筒状フィルム７中の物品９の前後位置で横シール手段４を構成する上下のシール体１０，１１によって、筒状フィルム７を挟持して筒状フィルム７の搬送方向に対し交差する左右方向に横シールと切断を行ってピロー包装品を得るよう構成されている。 The horizontal bag making and filling machine according to the first embodiment shown in FIG. 1 forms a belt-like film 6 drawn out from a film supply source 1 into a tubular shape by bag making means 2, and forms a tubular film 7 by vertical sealing means 3. The upper and lower sealing bodies constituting the horizontal sealing means 4 at the front and rear positions of the articles 9 in the cylindrical film 7 after the articles 9 are supplied into the cylindrical film 7 at predetermined intervals by the supply conveyor 8 while performing vertical sealing. 10 and 11, the cylindrical film 7 is sandwiched between the horizontal direction and the transverse direction intersecting the conveying direction of the cylindrical film 7 to obtain a pillow package product.

フィルム供給源１から製袋手段２までのフィルム案内経路には、帯状フィルム６を巻掛け案内する複数のガイドローラ１２と、フィルム供給源１からフィルムを引き出すフィルム搬送手段としての一対のローラからなる繰出手段１３，１４が配設され、該繰出手段１３，１４及びガイドローラ１２より下流にはフィルム進入ガイド手段１５及び印刷手段１６が配設されている。また、フィルム案内経路には、帯状フィルム６に印刷されたレジマークを検知するレジマークセンサ１９が設置されている。フィルム進入ガイド手段１５は、帯状フィルム６を巻掛け案内する一対の移動ローラ１７，１８と、各移動ローラ１７，１８の位置を調節し得るように、各移動ローラ１７，１８の両端を支持する進入角調節部１５ａからなり、移動ローラ１８（フィルム進入ガイドローラ）に巻き掛けられた帯状フィルム６が製袋手段２に向けて所定の角度で案内されるように、両移動ローラ１７，１８の位置が調節されて位置決めされる。 The film guide path from the film supply source 1 to the bag making means 2 includes a plurality of guide rollers 12 for winding and guiding the belt-like film 6 and a pair of rollers as film conveying means for drawing the film from the film supply source 1. The feeding means 13 and 14 are disposed, and the film entry guide means 15 and the printing means 16 are disposed downstream of the feeding means 13 and 14 and the guide roller 12. A registration mark sensor 19 that detects registration marks printed on the belt-like film 6 is installed in the film guide path. The film entry guide means 15 supports a pair of moving rollers 17 and 18 for winding and guiding the belt-like film 6 and both ends of the moving rollers 17 and 18 so that the positions of the moving rollers 17 and 18 can be adjusted. The moving film rollers 17 and 18 are configured so that the belt-shaped film 6 which is composed of the entering angle adjusting portion 15a and is wound around the moving roller 18 (film entering guide roller) is guided toward the bag making means 2 at a predetermined angle. The position is adjusted and positioned.

印刷手段１６は、移動ローラ１８と一体で移動して、帯状フィルム６の展張域で帯状フィルム６に日付印字等の所要の印刷をし得るようにフィルム進入ガイド手段１５に配設されており、詳述すると、移動ローラ１８のフィルム巻掛け部１８ａに対し展張した状態で接触している帯状フィルム６の接触部分に対し印刷手段１６の印刷部１６ａが所要の印刷を施し得るよう配設される。このため、フィルム巻掛け部１８ａと、製袋手段２において物品９が筒状フィルム７に受け渡される受け渡し位置との間は、複数の包装袋分に相当する印刷完了済みの帯状フィルム６が筒状に成形されるべく、待機する印刷フィルム待機領域とされている。印刷手段１６としてはサーマルリボンやインクジェット方式等のプリンタが採用される。 The printing means 16 is disposed in the film entry guide means 15 so as to move integrally with the moving roller 18 and perform necessary printing such as date printing on the strip film 6 in the stretched area of the strip film 6. More specifically, the printing unit 16a of the printing means 16 is arranged so as to perform the required printing on the contact portion of the belt-like film 6 that is in contact with the film winding portion 18a of the moving roller 18 in a stretched state. . For this reason, between the film winding part 18a and the delivery position where the article 9 is delivered to the tubular film 7 in the bag making means 2, the belt-like film 6 that has been printed corresponding to a plurality of packaging bags is tubular. In order to be formed into a shape, a print film standby area is set on standby. A printer such as a thermal ribbon or an ink jet method is employed as the printing unit 16.

供給コンベヤ８は、無端状のチェーン２０の外周に一定間隔で配設された各押送体２１が、一包装袋分のフィルム長と略同一ピッチ間隔で搬入された一包製袋分の物品９を押して製袋手段２へ一定速度で送るよう、モータＭ４により駆動制御される。また、供給コンベヤ８には該供給コンベヤ８から、製袋手段２で成形された筒状フィルム７に物品９を受け渡す受け渡し位置より上流側に物品９の到来を検知する物品検知手段としての光電センサ２２が設置されており、物品９が検知される位置と受け渡し位置との間に上記印刷フィルム待機領域に置かれた印刷完了済みの包装袋分の帯状フィルム６に対応した物品９を載置し得る載置領域が設けられている。 The supply conveyor 8 is an article 9 for one bag made by feeding each pusher 21 arranged on the outer periphery of an endless chain 20 at a regular interval at a pitch substantially equal to the film length of one packaging bag. The motor M4 is driven and controlled so as to push and feed the bag making means 2 at a constant speed. Further, the supply conveyor 8 has a photoelectric as an article detection means for detecting the arrival of the article 9 upstream from the delivery position for delivering the article 9 from the supply conveyor 8 to the tubular film 7 formed by the bag making means 2. A sensor 22 is installed, and the article 9 corresponding to the belt-like film 6 for the printed packaging bag placed in the print film standby area is placed between the position where the article 9 is detected and the delivery position. A possible mounting area is provided.

前述した繰出手段１３，１４、縦シール手段３、横シール手段４、供給コンベヤ８を駆動するモータＭ１〜Ｍ４には、エンコーダＥ１〜Ｅ４が付設されており、各エンコーダＥ１〜Ｅ４やレジマークセンサ１９や光電センサ２２やデータ入力手段２３からの信号は制御部２４に入力される。データ入力手段２３は、包装品種毎に、一包装袋分のフィルム長や所定時間あたりの包装速度としての包装能力等の包装条件などを設定することができる。制御部２４は、これらの入力信号に基づき、繰出手段１３，１４や供給コンベヤ８や印刷手段１６や縦シール手段３や横シール手段４が連係動作するよう駆動制御する。従って、製袋手段２で成形された筒状フィルム７の搬送位置に対して供給コンベヤ８による物品９の送り込み位置が合うように、筒状フィルム７に物品９が押送体２１により所定間隔毎に供給される。その際、押送体２１で物品９を筒状フィルム７中に押し込む必要があるため、供給コンベヤ８の搬送速度は縦シール手段３或いは繰出手段１３，１４で構成されるフィルム搬送手段によって走行する筒状フィルム７の搬送速度より略同速或いは若干速く設定されている。なお、縦シール手段３にはモ−タから駆動を受けて回転する一対の送りローラ５がフィルム搬送手段を構成している。 Encoders E1 to E4 are attached to the motors M1 to M4 for driving the feeding means 13 and 14, the vertical sealing means 3, the horizontal sealing means 4 and the supply conveyor 8, and the encoders E1 to E4 and registration mark sensors are attached. 19, signals from the photoelectric sensor 22 and the data input means 23 are input to the control unit 24. The data input means 23 can set the packaging conditions such as the film length for one packaging bag and the packaging capability as the packaging speed per predetermined time for each packaging type. Based on these input signals, the control unit 24 drives and controls the feeding means 13, 14, the supply conveyor 8, the printing means 16, the vertical sealing means 3, and the horizontal sealing means 4 to be linked. Therefore, the article 9 is fed to the tubular film 7 at every predetermined interval by the feeding body 21 so that the feeding position of the article 9 by the supply conveyor 8 matches the transport position of the tubular film 7 formed by the bag making means 2. Supplied. At that time, since it is necessary to push the article 9 into the cylindrical film 7 by the feeding body 21, the conveying speed of the supply conveyor 8 is a cylinder that is run by the film conveying means constituted by the vertical sealing means 3 or the feeding means 13,14. It is set to be substantially the same speed or slightly faster than the conveying speed of the film 7. A pair of feed rollers 5 that rotate by receiving a drive from the motor constitutes a film conveying means.

制御部２４は、供給コンベヤ８において、光電センサ２２が物品の到来を検知する毎に入力信号を受け、エンコーダＥ３或いはＥ１からの情報に基づき、印刷手段１６に印刷指令を行うと共に、モータＭ１，Ｍ３に帯状フィルム６を一包装袋分毎（一包装に要する長さ毎）、走行させる指令を行う。従って、印刷手段１６の印刷部１６ａは、一包装に要する長さの帯状フィルム６（一包装袋分の帯状フィルム）の特定箇所に、毎回フィルム巻掛け部１８ａで印刷を施す。供給コンベヤ８による物品９の搬送に伴い光電センサ２２による物品９の検知が連続的に行われると、検知された物品９に対応した包装袋分だけ帯状フィルム６が連続的に走行し、印刷手段１６による印刷も連続的に行われるため、供給コンベヤ８における載置領域に載置された物品９に対応した包装袋分だけ印刷完了済みの帯状フィルム６が印刷フィルム待機領域に送られる。そして、次々に物品９が検知されたことから載置領域から溢れ出ることになった、先行して載置された一包装袋分の物品９は、受け渡し位置を経て、その一包装袋分の物品９に対応して印刷された包装袋になる予定の筒状フィルム７中に供給される。この時、他の検知された夫々の物品９は載置領域に載置されており、夫々の物品９に対応して印刷された印刷完了済みの包装袋分の帯状フィルム６は、印刷フィルム待機領域で待機する。その後、更に光電センサ２２が次の一包装袋分に対応する物品９を検知すると、印刷フィルム待機領域にて待機中の印刷完了済みの包装袋分の次の一包装袋分とすべく帯状フィルム６に印刷が行われる。なお、供給コンベヤ８の載置領域への一包装袋分の物品９の供給が途切れた場合には、帯状フィルム６が一包装袋分搬送されても、制御部２４は印刷手段１６に印刷指令を行わず、帯状フィルム６を一包装袋分、印刷フィルム待機領域へ走行させる指令を行う。即ち、欠品に対応する包装袋には印刷が行われない。 The control unit 24 receives an input signal every time the photoelectric sensor 22 detects the arrival of an article in the supply conveyor 8, and issues a print command to the printing means 16 based on information from the encoder E <b> 3 or E <b> 1. The M3 is instructed to run the belt-like film 6 every one packaging bag (every length required for one packaging). Therefore, the printing unit 16a of the printing unit 16 performs printing on the specific portion of the strip-shaped film 6 having a length required for one packaging (a strip-shaped film for one packaging bag) by the film winding unit 18a every time. When the article 9 is continuously detected by the photoelectric sensor 22 as the article 9 is conveyed by the supply conveyor 8, the belt-like film 6 continuously travels as much as the packaging bag corresponding to the detected article 9, and printing means Since the printing by 16 is also continuously performed, the belt-like film 6 that has been printed by the amount corresponding to the packaging bag corresponding to the article 9 placed in the placement area of the supply conveyor 8 is sent to the printing film standby area. Then, the articles 9 for one packaging bag placed in advance, which overflowed from the placement area because the articles 9 were detected one after another, passed through the delivery position and passed through the delivery position. It is fed into a cylindrical film 7 which is to be a printed packaging bag corresponding to the article 9. At this time, each of the other detected articles 9 is placed in the placement area, and the belt-like film 6 for the printed packaging bag corresponding to each article 9 is printed on standby. Wait in the area. Thereafter, when the photoelectric sensor 22 further detects the article 9 corresponding to the next one packaging bag, the belt-like film is set to the next packaging bag corresponding to the printed packaging bag waiting in the printing film standby area. 6 is printed. When the supply of the article 9 for one packaging bag to the placement area of the supply conveyor 8 is interrupted, the control unit 24 instructs the printing means 16 to print even if the belt-like film 6 is conveyed for one packaging bag. The belt film 6 is instructed to travel to the print film standby area for one packaging bag. That is, printing is not performed on the packaging bag corresponding to the shortage.

第１実施形態は下記の効果を有する。
（１）供給コンベヤ８の載置領域に、印刷フィルム待機領域に位置する印刷完了済みの包装袋分に対応した物品９を載置している状態で、光電センサ２２が印刷完了済みの包装袋分の次の一包装袋分に対応する次の物品９を検知して、該次の物品９の検知に基づき、印刷手段１６が該次の一包装袋分に対応した印刷を行う。即ち、光電センサ２２によって検知された一包装袋分の物品９に対応して帯状フィルム６に一包装袋分だけ印刷が施される。加えて、印刷された帯状フィルム６が製袋手段２に向けて搬送される。従って、供給コンベヤ８の上流側の処理機（不図示）から、一定間隔で供給されるべき物品９の途切れが生じた際には、印刷手段１６が欠品によって生じた空袋に印刷する等の不要な印刷を行うことなく包装することができ、インクリボンやインク液等の印刷媒体の消耗を低減することができる。 The first embodiment has the following effects.
(1) A packaging bag in which the photoelectric sensor 22 has been printed in a state where the article 9 corresponding to the printed packaging bag located in the printing film standby region is placed in the placement area of the supply conveyor 8 The next article 9 corresponding to the next one packaging bag is detected, and based on the detection of the next article 9, the printing unit 16 performs printing corresponding to the next one packaging bag. That is, printing is performed on the belt-like film 6 for one packaging bag corresponding to the article 9 for one packaging bag detected by the photoelectric sensor 22. In addition, the printed belt-like film 6 is conveyed toward the bag making means 2. Therefore, when an article 9 to be supplied from a processing machine (not shown) on the upstream side of the supply conveyor 8 is interrupted, the printing means 16 prints on an empty bag caused by a shortage. Can be packaged without unnecessary printing, and consumption of printing media such as ink ribbons and ink liquids can be reduced.

（２）生産開始前にフィルムに対する印刷位置や印刷の濃さ等の表示状態を確認する場合には立体化された袋の状態で確認する方が表示状態の不備等を発見し易く、光電センサ２２によって検知された物品９に対応する包装袋分だけの印刷を行うため、その検知された物品９が横シール手段４に搬送される間に不要な印刷が行われることはない。 (2) When confirming the display state such as printing position and printing density on the film before the start of production, it is easier to find defects in the display state by checking in the three-dimensional bag state. Since printing is performed only for the packaging bag corresponding to the article 9 detected by 22, unnecessary printing is not performed while the detected article 9 is conveyed to the horizontal sealing means 4.

（３）印刷手段１６をフィルム進入ガイドローラとしての移動ローラ１８に配設し、或いはその近傍に配設したことにより、印刷完了済みの包装袋数を少なくすることができ、その印刷完了済みの包装袋分に対応した物品９を載置する供給コンベヤ８の載置領域を短くすることが可能になり、横形製袋充填機全体の小型化が可能になる。 (3) By arranging the printing means 16 on the moving roller 18 as a film entry guide roller or in the vicinity thereof, the number of printed packaging bags can be reduced, and the printing has been completed. It is possible to shorten the placement area of the supply conveyor 8 on which the articles 9 corresponding to the packaging bags are placed, and the entire horizontal bag making and filling machine can be downsized.

（４）製袋手段２に向けて帯状フィルム６が所定の角度で案内されるように位置決めされる移動ローラ１８をフィルム巻掛け部１８ａばかりでなく、印刷時における印刷対象物である帯状フィルム６を支持する台としても兼用したので、部品点数を少なくすることができる。 (4) The moving roller 18 positioned so that the belt-like film 6 is guided at a predetermined angle toward the bag making means 2 is not only the film winding portion 18a but also the belt-like film 6 which is a printing object at the time of printing. Since this is also used as a stand for supporting the, the number of parts can be reduced.

次に、本発明の第２実施形態に係る横形製袋充填機について第１実施形態との相違点を中心に図２を参照して説明する。
第２実施形態の供給コンベヤ８は、製袋手段２で成形される筒状フィルム７中へ物品９を供給する無端状ベルトからなる第一コンベヤ２５と、第一コンベヤ２５の上流に接続された無端状ベルトからなる第二コンベヤ２６とを備えている。第一コンベヤ２５は、帯状フィルム６を走行させるモータＭ３により、帯状フィルム６の搬送速度と略同じ速度で、且つ、同調して走行駆動される。第二コンベヤ２６は、エンコーダＥ４が付設された速度制御モータＭ４により走行駆動され、第二コンベヤ２６より上流側の処理装置（不図示）から受け入れた物品９を一定速度で第一コンベヤ２５へ搬送する。物品検知手段としての光電センサ２２は第二コンベヤ２６の下流端付近に設置されており、物品９の到来を検知する。載置領域は、第二コンベヤ２６上で物品９が検知される位置と、第一コンベヤ２５から製袋手段２で成形された筒状フィルム７に物品９を受け渡す受け渡し位置との間に設けられている。 Next, a horizontal bag making and filling machine according to a second embodiment of the present invention will be described with reference to FIG. 2 focusing on differences from the first embodiment.
The supply conveyor 8 of the second embodiment is connected to a first conveyor 25 comprising an endless belt for supplying articles 9 into the tubular film 7 formed by the bag making means 2 and upstream of the first conveyor 25. And a second conveyor 26 made of an endless belt. The first conveyor 25 is driven and driven in synchronism with a speed substantially equal to the conveying speed of the belt-like film 6 by a motor M3 that travels the belt-like film 6. The second conveyor 26 is driven by a speed control motor M4 provided with an encoder E4, and conveys the article 9 received from a processing device (not shown) upstream of the second conveyor 26 to the first conveyor 25 at a constant speed. To do. The photoelectric sensor 22 as the article detection means is installed near the downstream end of the second conveyor 26 and detects the arrival of the article 9. The placement area is provided between a position where the article 9 is detected on the second conveyor 26 and a delivery position where the article 9 is delivered from the first conveyor 25 to the tubular film 7 formed by the bag making means 2. It has been.

第２実施形態においては、一包装袋分に対応する先行の物品９（前側の物品９）と、その次の一包装袋分に対応する後続の物品９（後側の物品９）との間隔が広がり過ぎている場合（或いは間隔が狭い場合）などに、第二コンベヤ２６上における光電センサ２２により検知された上記前後の物品９の移動情報に基づき、第一コンベヤ２５と第二コンベヤ２６との相対的な搬送速度を変更して前後の物品９の間隔を調整し、各物品９を筒状フィルム７中に円滑に供給して不要な印刷を防止すると共に空袋の発生を防止する。即ち、モータＭ１，Ｍ３を加減速させると共にフィルム搬送に連係動作するようモータＭ２を駆動制御して、筒状フィルム７を余すことなく筒状フィルム７に一定の袋長さの包装袋が続くように、光電センサ２２によって検知された物品９が第一コンベヤ２５に乗り移るまでに、該物品９と、該物品９より一つ前に検知された、一包装分先行した物品９との間隔（第一コンベヤ２５の受渡しタイミング）を調整する。従って、物品９の間隔を調整して、筒状フィルム７中に夫々の物品９を円滑に供給することができる。 In the second embodiment, the distance between the preceding article 9 (front article 9) corresponding to one packaging bag and the succeeding article 9 (rear article 9) corresponding to the next packaging bag. Is excessively spread (or when the interval is narrow), etc., based on the movement information of the preceding and following articles 9 detected by the photoelectric sensor 22 on the second conveyor 26, The relative conveyance speed is changed to adjust the distance between the front and rear articles 9 and each article 9 is smoothly supplied into the tubular film 7 to prevent unnecessary printing and to prevent the occurrence of empty bags. That is, the motor M1 is driven and controlled so that the motors M1 and M3 are accelerated and decelerated and linked to the film conveyance, so that the cylindrical film 7 is continued to a packaging bag having a fixed bag length without leaving the cylindrical film 7. In addition, by the time the article 9 detected by the photoelectric sensor 22 is transferred to the first conveyor 25, the interval between the article 9 and the article 9 preceding by one package detected before the article 9 (first order). The delivery timing of one conveyor 25 is adjusted. Therefore, the interval between the articles 9 can be adjusted to smoothly supply each article 9 into the tubular film 7.

この場合も、光電センサ２２が物品９を検知すると、一包装袋分に印刷が行われ、第１実施形態と同様に検知された物品９に対応した包装袋分だけ印刷完了済みの帯状フィルム６が、印刷フィルム待機領域に送られ、そして更に物品９の検知が続き、載置領域から溢れ出ることになった、先行して載置された一包装袋分の物品９は、受け渡し位置を経て、その一包装袋分の物品９に対応して印刷された包装袋となる前の筒状フィルム７中に供給される。従って、物品９の間隔を調整して、筒状フィルム７中に物品９を円滑に供給することができると共に、空袋の発生と不要な印刷を防止することができ、インクリボンやインク液の印刷媒体及びフィルムの消耗を低減することができる。また、第１実施形態の効果（２）〜（４）と同様の効果を奏する。なお、生産予定の最後の物品９が検知された後、物品９が検知されないことから、第一コンベヤ２５上に停止状態で載置される物品９を包装するに際しては、印刷手段１６の作動を以後停止状態に設定切換えした後で供給コンベヤ８とフィルム搬送手段と横シール手段４を連係動作させて包装品を得るように駆動制御する等の対応で、不要な印刷を防止することは可能である。 Also in this case, when the photoelectric sensor 22 detects the article 9, printing is performed for one packaging bag, and the belt-like film 6 that has been printed for the packaging bag corresponding to the detected article 9 as in the first embodiment. Is sent to the print film standby area, and further detection of the article 9 continues, and the article 9 for one packaging bag placed in advance, which has overflowed from the placement area, passes through the delivery position. Then, it is supplied into the cylindrical film 7 before becoming a printed packaging bag corresponding to the article 9 for one packaging bag. Accordingly, the interval between the articles 9 can be adjusted so that the articles 9 can be smoothly supplied into the tubular film 7, and the occurrence of empty bags and unnecessary printing can be prevented. The consumption of the print medium and the film can be reduced. Moreover, there exists an effect similar to effect (2)-(4) of 1st Embodiment. In addition, since the article 9 is not detected after the last article 9 to be produced is detected, the operation of the printing means 16 is performed when packaging the article 9 placed on the first conveyor 25 in a stopped state. It is possible to prevent unnecessary printing by responding to the drive control so as to obtain a packaged product by operating the supply conveyor 8, the film conveying means and the lateral seal means 4 in a linked manner after the setting is changed to the stop state. is there.

次に、本発明の第３実施形態に係る横形製袋充填機について第１実施形態との相違点を中心に図３を参照して説明する。
第３実施形態では、第１実施形態のフィルム進入ガイド手段１５がフィルム供給源１からの帯状フィルム６を引き出す繰出手段を配設したフィルム進入ガイド手段１５に変更されている。フィルム進入ガイド手段１５は、繰出手段としての駆動ローラ２８、従動ローラ２９及び該駆動ローラ２８を回転駆動するモータＭ３、モータＭ３に付設されたエンコーダＥ３を有しており、これらは進入角調節部１５ａに対しその長手方向に移動調節可能に支持されている。フィルム供給源１から引き出された帯状フィルム６は、駆動ローラ２８に巻き掛けられ、駆動ローラ２８と従動ローラ２９との間で挟持されてから従動ローラ２９に巻き掛けられた後、従動ローラ２９より略斜め下方に配設された製袋手段２に案内される。印刷手段１６は、従動ローラ２９（フィルム進入ガイドローラ）と一体で移動して、従動ローラ２９のフィルム巻掛け部２９ａに対し展張した状態で接触している帯状フィルム６の接触部分に対し印刷手段１６の印刷部１６ａが所要の印刷を行なうよう配設されている。このため、フィルム巻掛け部２９ａと製袋手段２における受け渡し位置との間は、複数の包装袋分に相当する印刷完了済みの帯状フィルム６が筒状に形成されるべく、待機する印刷フィルム待機領域とされている。 Next, a horizontal bag making and filling machine according to a third embodiment of the present invention will be described with reference to FIG. 3 focusing on differences from the first embodiment.
In the third embodiment, the film entry guide means 15 of the first embodiment is changed to a film entry guide means 15 provided with a feeding means for pulling out the belt-like film 6 from the film supply source 1. The film entry guide means 15 has a driving roller 28 as a feeding means, a driven roller 29, a motor M3 for rotationally driving the driving roller 28, and an encoder E3 attached to the motor M3. It is supported so as to be movable and adjustable in the longitudinal direction with respect to 15a. The belt-like film 6 drawn from the film supply source 1 is wound around the driving roller 28, sandwiched between the driving roller 28 and the driven roller 29, wound around the driven roller 29, and then from the driven roller 29. It is guided to the bag making means 2 disposed substantially obliquely below. The printing means 16 moves integrally with the driven roller 29 (film entry guide roller) and prints on the contact portion of the belt-like film 6 that is in contact with the film winding portion 29a of the driven roller 29 in a stretched state. Sixteen printing units 16a are arranged to perform required printing. For this reason, between the film winding part 29a and the delivery position in the bag making means 2, the print film standby waiting so that the printed film strip 6 corresponding to a plurality of packaging bags can be formed into a cylindrical shape. It is an area.

第３実施形態においては、第１実施形態と同様な効果を奏し、更にフィルム進入ガイドローラを従動ローラ２９で構成したことで、フィルム供給源１から製袋手段２までのフィルム案内経路が簡素になり、帯状フィルム６に対する印刷手段１６の干渉を減らすことができる。 In the third embodiment, the same effect as in the first embodiment is achieved, and the film entry guide roller is constituted by the driven roller 29, so that the film guide path from the film supply source 1 to the bag making means 2 is simplified. Thus, the interference of the printing means 16 with the strip film 6 can be reduced.
