  In a bag making and filling machine equipped with a multi-row bag making and filling unit, if a different film supply unit is provided in each row of the bag making and filling unit, it is necessary to connect old and new films with film consumption for each row. is there.

  Here, even if all the rows are loaded with unused raw rolls at the same time and the film is exhausted, the total length of the film wound around each original roll is not fixed due to film production problems, The film connection time of each row cannot be constant. Also, different types of goods are packaged in each row, and the packaged products are combined and sent to a processing machine such as a boxing machine connected to the downstream side in units of a plurality of packaged products. If the product is food, etc., all the packaged products for each set including the non-defective package together with the defective packaged product where the film connection part is located are discharged out of the line and downstream by the combination of only the non-defective product. It is preferable to carry it toward the processing machine on the side. However, since the film connection time is different in each row as described above, each time the film is connected in each row, a plurality of non-defective packages obtained in other rows are discharged out of the system, and the production efficiency is increased. It will decline.

  In addition, when the non-defective product discharged together with the defective product is, for example, a packaged food such as frozen dessert, the product discharged outside the system is not handled as a non-defective product and is disposed of. For this reason, waste due to disposal of non-defective products will occur.

  That is, an object of the present invention is to provide a bag making and filling machine that can increase the productivity by reducing the number of rejected non-defective products and suppress the waste of the product in view of the above-described problems related to film connection.

In order to overcome the above-mentioned problems and achieve the intended purpose, a bag making and filling machine according to the invention of claim 1 forms a film drawn from a raw roll into a cylindrical shape and applies a horizontal seal to the film.

In response to a detection signal by any one of the detection means of the film supply unit, at least the film in use in each film supply unit in the other row is cut, and the film end in use in the film supply unit in each row The terminal cutting means and the film connecting means are controlled to be connected so as to connect the film starting end of the spare original fabric roll.

  In the invention according to claim 2, each of the film supply sections is disposed so that the film drawing length from the film connection position in the film connection means to the position where the film is laterally sealed differs from each other. In response to a detection signal from one of the detection means, the end cutting means and the film connection means are controlled to shift the timing of cutting and connecting the film in the other row according to the difference in the film drawing length. The summary is as follows.

  In the invention which concerns on Claim 3, the discharge | emission means is arrange | positioned in the downstream in the said bag making filling part, and the defective packaging product containing the film connection part connected with the said film connection means, and discharge | emission at the same time as this defective packaging product The gist of the invention is that the operation of the discharge means is controlled so as to discharge together with the other row of packaged products reaching the means.

  In the invention which concerns on Claim 4, each of the horizontal sealing means which carries out the horizontal seal of the said film, and the cutting | disconnection means which cut | disconnects the film horizontally sealed by this horizontal sealing means are each arrange | positioned, and the film connection connected by the said film connection means The gist is that the cutting means is switched to temporarily stop cutting the film when the part reaches the cutting position in the cutting means.

  The gist of the invention according to claim 5 is that when the operation of the cutting means is suspended, the transverse sealing operation by the transverse sealing means is temporarily suspended.

  According to the bag making and filling machine according to the present invention, when consumption of any one of the multi-row film supply units is detected, the film is cut and connected at the same time in all rows. So, for example, when processing packaged products of different varieties for each set, the number of non-defective products to be disposed together with defective products can be reduced by matching the timing of discharging the packaged products including the film connection parts as defective products outside the system. Decrease and increase productivity.

  The vertical bag making and filling machine shown in FIG. 1 has a plurality of bag making and filling portions 14 (four in the embodiment) arranged in parallel to obtain a packaged product 12 by film-wrapping food made of frozen confectionery or the like as the article 10. A film supply unit 16 that draws and supplies the belt-like film f toward the bag making and filling unit 14 is provided corresponding to each bag making and filling unit 14.

  In the bag making and filling unit 14, the belt-like film f drawn from the film supply unit 16 is formed into a cylindrical shape by the bag making means 18 and continuously conveyed downward by the conveying means 20 including a feed roller and the like. A vertical sealing means 22 is provided below the conveying means 20 for applying a vertical seal to the overlapping portion of the cylindrically formed film f. Further, at a position spaced apart from the vertical sealing means 22 by a predetermined distance (horizontal sealing / cutting position), a horizontal sealing means 24 for performing horizontal sealing in a direction crossing the film transport direction is disposed. The horizontal sealing means 24 includes a cutting means 25 (see FIG. 4) for operating the cutter by a driving means such as a cylinder. When the horizontal sealing means 24 performs horizontal sealing on the film, the cutting means 25 is operated to separate the film. One package of the packaged product 12 can be obtained.

  Below the horizontal sealing means 24, the packaging product 12 that is laterally sealed and cut by the horizontal sealing means 24 and dropped can be discharged out of the system between the discharge conveyor 28 that conveys the packaged goods 12 downstream. A discharge means 30 is provided. As shown in FIG. 1, the discharge means 30 includes a chute 30 a that is rotated by a drive means 30 b made of an air cylinder. The chute 30 a can guide the packaged article 12 falling from above toward the discharge conveyor 28. The position and the discharge position for discharging to the outside of the system without being transferred to the discharge conveyor 28 are set.

  A collecting portion 26 is connected to the downstream side of each discharge conveyor 28. As shown in FIG. 2, the package 12 guided from each bag making and filling portion 14 via a chute 30a is spaced apart from each other at the collecting portion 26. So that the distance between the discharge conveyors 28 becomes narrower as it goes from the transfer start end to the transfer end. With such a configuration, the transport length to each collecting section 26 in each discharge conveyor 28 is different, and the transport speed of each discharge conveyor 28 is set according to the transport length, and each row of packaging in each collecting section 26. Article 12 is configured to be able to reach simultaneously.

  The film supply sections 16 in each row are arranged so that the separation distance to the bag making and filling section 14 is different for each row. In the embodiment, the film supply portions 16 are arranged stepwise as shown in FIG. The difference in the film guide length between the supply units 16 and 16 is set to 2 cut pitches when the film length (cut pitch) required for one package is set, and the bag filling from each film supply unit 16 The difference in the film guide lengths leading up to the part 14 is also set to be equal to the difference. In addition, in the following description, when distinguishing a row | line | column by the film supply part 16 from which the said separation distance differs, about the thing which belongs to each row | line, it is 1st, 2nd, 3rd in an order from a short separation distance before a name. And 4th.

  As shown in FIG. 1 or FIG. 3, the film supply unit 16 is provided with loading means capable of loading a plurality of original fabric rolls 34. The support portions 32, 32 are provided, and the support rolls 32 are loaded into the respective support portions 32. The belt-like film f drawn out from the original roll 34 loaded in one support part 32 is supplied to the bag making and filling part 14 through the guide roller 36 and the film connecting means 44. Further, a detecting means 42 for detecting the film end at a position wound around the guide roller 36 is provided. Further, a feeding means 38 provided with a feeding roller is disposed between the film connecting means 44 and the bag making and filling unit 14, and the belt-like film f drawn from the original roll 34 by the feeding means 38 is disposed. It is configured to supply toward the bag making means 18. The feeding roller is provided with an encoder 40 (see FIG. 4) so as to be able to detect the film conveyance amount supplied to the bag making and filling unit 14.

  A film connecting means 44 for connecting old and new films is disposed at a film connecting position between the upper and lower support portions 32 and 32. The film connecting means 44 includes a crimping means 46 configured to move the pair of crimping rolls 46a and 46a close to and away from each other by a required driving means. Further, an end cutting means 48 for cutting the film f in the width direction is disposed in the film conveyance path from the original fabric roll 34 toward the pressure bonding means 46. Then, as shown in FIG. 3, the film f drawn out from any one of the original rolls 34 is wound around one of the open pressure rolls 46a and corresponds between the pressure rolls 46a and 46a. It is configured to be supplied toward the bag making and filling unit 14. On the other hand, the leading end of the new film f drawn out from the other original roll 34 serving as a preliminary roll is wound around the other press roll 46a and pulled out to a predetermined position beyond both the press rolls 46a, 46a. In addition, a sticking member such as a double-sided tape is stuck toward the width direction of the film in the horizontal guide portion close to the upstream side of the pressure roll 46a. And the film f in use and the new film f are pinched and conveyed by the action | operation of both the crimping | compression-bonding rolls 46a and 46a, and the pasting site | part of the pasting member in the new film f passes through the crimping rolls 46a and 46a. The old and new films are crimped to connect the two films f and f.

  The end cutting means 48 is activated when the corresponding detecting means 42 detects the end of the film f drawn from the original roll 34, and cuts the film f in use on the upstream side of the pressure roll 46a. Is done. A tension roller 50 is disposed on the downstream side of the film connecting means 44, and the film f can be stably conveyed even when a back tension is temporarily applied to the film f by the operation of the pressure-bonding roll 46a. it can.

  A mark sensor 52 for detecting a registration mark attached to the film is disposed on the downstream side of the feeding means 38. Based on the registration mark detection signal by the mark sensor 52, the film transport position is corrected and controlled, and the operation timing of the pressure-bonding rolls 46a, 46a is controlled when the old and new films are connected by the film connecting means 44. The conveyance positions of both films are adjusted.

  As shown in FIG. 4, the control means 54 of the vertical bag making and filling machine is capable of driving and controlling each of the horizontal sealing means 24, the cutting means 25, the discharging means 30, the crimping means 46, and the terminal cutting means 48 in each row. Connected so that detection signals of the detection means 42 and the mark sensor 52 in each row are inputted, and a transmission pulse from the encoder 40 arranged in the feeding means 38 is inputted to the film. Can be obtained.

  In the control means 54, the “cut pitch” as the film length required for one packaging described above, or the horizontal sealing position where the horizontal sealing means 24 applies the horizontal seal from the film connection position where the old and new films are connected by the crimping means 46. Various control data such as numerical data corresponding to the “film drawing length” as the values up to are preset by an input means (not shown). The control means 54 operates to control the lateral sealing means 24 and the cutting means 25 so as to laterally seal and cut the film every packaging cycle in which the film is conveyed by one cut pitch. In addition, the control unit 54 receives a signal that detects the end of the film f from any one of the plurality of detection units 42, so that the film f in use in the film supply units 16 in all rows is input. Each terminal cutting means 48 and each film connecting means 44 are controlled to cut and connect the film f for switching between the film f and the preliminary roll film f. At this time, the control means 54 sets the “film drawing length” of each of the other rows with respect to the row where the end of the film f is detected by the detecting means 42 so that the film connection portions of all rows reach the horizontal seal portion at the same time. The discharge means 30 is controlled so that the film cutting time by each terminal cutting means 48 and the film connection time by each film connecting means 44 are shifted with respect to the difference, and the defective packaging product including the film connecting part is discharged out of the system. Control the operation. In addition, when the period in which the film connection part reaches the horizontal seal portion is converted as the number of packaging cycles, the “wrapping cycle number” A is set to “L” for the “film draw length” and P for the “cut pitch”. , A = P / L. As in this example, when a package 12 having a short cut pitch is obtained with a connection form in which the connection part of the old and new films has a connection allowance for both films, the number of packaging cycles A ± 1 at which the film connection part reaches the horizontal seal portion. During this period, the discharge means 30 is controlled to be discharged so as to continuously discharge three packaged products 12 as defective packaged products out of the system.

(Effects of Example)
Next, the operation of the vertical bag making and filling machine according to the above-described embodiment will be described.

  As described above, the film supply units 16 in each row have different separation distances to the bag making and filling unit 14 for each row. Therefore, the row in which the end of the film f is detected by the detecting means 42 and the film drawing length in the other row are respectively detected. Based on the difference, the cutting timing of the film end of each row by the end cutting means 48 is controlled to be shifted from the timing of film connection by operating the press roll 46a in the film connecting means 44. That is, (A) when the end of the film f is detected by the detection means 42 of the line with the longest film drawing length, the difference in the film drawing length from the detection line increases in the third to first order. The cutting timing and the connecting timing of f are sequentially delayed. (B) When the end of the film f is detected by the detection means 42 of the row with the shortest film drawing length, all the film supply sections 16 simultaneously The film f is cut and connected, and (C) when the end of the film is detected by the detection means 42 having an intermediate film drawing length, the film supply section 16 having a film drawing length longer than that of the detection row. In contrast, while the film f is cut and connected at the same time, in the film supply section 16 in which the film drawing length is shorter than the detection row, the difference in the film drawing length increases. Each end cutting means 48 and the film connection means 44 to perform sequentially delaying the disconnection timing and connection time of beam f control operation.

  The film withdrawal length is a known value corresponding to the position of the film supply unit 16 in each row, and the film withdrawal length is shorter than the film withdrawal length in the row where the film end is detected. The cutting time and connection time of the film f in the film supply unit 16 are respectively set as the difference in the number of packaging cycles A of each row calculated as described above with respect to the film drawing length of each row. Further, the control means 54 is arranged to cut the cutting means 25 when the film connecting portion connected by the film connecting means 44 reaches the horizontal seal portion at the time when the predetermined number of packaging cycles obtained from the film drawing length of each row is reached. The operation of the cutter may be temporarily stopped, and further, the horizontal sealing operation by the horizontal sealing means 24 may be controlled to be stopped so that the horizontal sealing and cutting of the film are not performed.

  The cases (A) to (C) will be specifically described below.

(A) When the film of the fourth film supply unit is completed In the fourth film supply unit 16 in which the film drawing length from the film connection position to the horizontal seal unit is set to the longest, the control means 54 is in use. By inputting the signal detected by the detection means 42 at the end of the film f, the end cutting means 48 is operated to cut the film f in use and conveyed toward the bag making and filling unit 14. The registration mark of the film f receives an input signal detected by the mark sensor 52, and at a predetermined timing according to the relationship with the film conveyance amount obtained from the encoder 40 so that the printing positions of the old and new films f and f match. The film end of the film f in use, which has been cut by the end cutting means 48 by operating the crimping means 46, and the film start end of the preliminary roll Press roll 46a, attached to the adhesive member to the starting end of the new film f by being conveyed is sandwiched 46a is attached to the film end in use old and new films f, f are connected. On the other hand, the cutting time of the film f in the order of the difference between the fourth film supply unit 16 and the film drawing length is small, that is, the third film supply unit 16, the second film supply unit 16, and the first film supply unit 16. Each connection time is delayed by 2 packaging cycles. In other words, the timing for delaying the cutting and connection timing of the film f is set to a predetermined timing when the number of packaging cycles has elapsed according to the difference in the film drawing length of each row as described above. The means 48 and the film connecting means 44 are sequentially operated to connect the end of the film f being used and the start of the new film f so that the printing positions of the old and new films f and f coincide with each other. Thereby, the time when the film connection site | part connected by the film connection means 44 of all the lines including the 4th film supply part 16 reaches a horizontal seal | sticker part can be made to correspond.

  Each of the packaged products 12 obtained by lateral sealing and cutting by the bag making and filling unit 14 of the entire row has a film connection portion, and after the horizontal sealing and cutting, they are When the discharge means 30 is reached, the operation of the discharge means 30 is controlled so that the chute 30a is rotated to the discharge position, and all rows of the packaged products 12 are simultaneously discharged out of the system as defective packages.

  The discharge means 30 rotates to the discharge position until the tubular film f is cut in the packaging cycle immediately before the packaging cycle in which the film connection portion reaches the horizontal seal portion, and the film connection portion becomes the horizontal seal portion. The operation is controlled to return to the guide position until the tubular film f is cut in the next packaging cycle after the packaging cycle immediately after the reaching packaging cycle is completed, and thereby the film connection portion is positioned in each row. A total of three packaged products including the packaged products 12 and 12 that are continuous before and after the packaged product 12 are discharged as defective packaged products.

(B) When the film of the first film supply section is finished In the first film supply section 16 in which the film drawing length from the film connection position to the horizontal seal section is set to the shortest, the end of the film f in use is When detected by the detection means 42, the control means 54 simultaneously operates the terminal cutting means 48 in the film supply sections 16 of all the rows, and sets the film connection means 44 so as to simultaneously perform the film connection as described above. Control.

  Film connection in the fourth film supply unit 16 is a row in which the film withdrawal length is set to the longest from the packaging cycle in which the film connection part connected by the first film supply unit 16 reaches the horizontal seal part when the predetermined number of packaging cycles has elapsed. Each of the entire rows of packaged articles 12 obtained by transverse sealing and cutting during the number of packaging cycles until the portion reaches the lateral seal portion is out of the system by the rotation of the chute 30a to the ejection position in the ejection means 30. To be discharged. The discharge means 30 in each row is such that the film connection site in the fourth film supply unit 16 is horizontal sealed from the packaging cycle immediately before the packaging cycle in which the film connection site connected by the first film supply unit 16 reaches the horizontal seal unit. The plurality of packaged articles 12 are continuously discharged out of the system while being held at the discharge position for the period up to the packaging cycle immediately after the packaging cycle reaching the part.

(C) When the film of the second or third film supply section is finished The film end is detected by the film supply section 16 in the row where the film drawing length from the film connection position to the horizontal seal section is set to the middle. The case will be described in the case of the third film supply unit 16. In the third film supply unit 16, when the end of the film f in use is detected by the detection unit 42, the control unit 54 determines the difference in the film withdrawal length between the third film supply unit 16 and the other row. Accordingly, the operation of the terminal cutting means 48 and the film connecting means 44 is controlled so as to shift the cutting timing and the connecting timing of the film f in the film supply sections 16 in the other rows. That is, the film f is cut and connected simultaneously with the fourth film supply unit 16 having a long film drawing length, and the second film supply unit 16 and the first film supply unit 16 having a short film drawing length are as described above. The terminal cutting means 48 and the film connecting means 44 are controlled so as to delay the cutting timing and the connecting timing of the film f in the order of decreasing difference in accordance with the difference in the film drawing length with respect to the third film supply section 16. Thereby, the film connection site | part by the 1st, 2nd film supply parts 16 and 16 used as the row | line | column with a short film | drawer length is the same packaging cycle as the time when the film connection site | part of the 3rd film supply part 16 reaches a horizontal seal part. At the same time, they reach the horizontal seals.

  And after the film connection part of the 1st-3rd film supply part 16 reaches | attains a horizontal seal part simultaneously, it is a horizontal seal * between the film connection part of the 4th film supply part 16 reaching the horizontal seal part. All of the four rows of packaged products 12 that have been cut are simultaneously discharged out of the system through the discharge means 30 in the same manner as described above. The discharge means 30 in each row is such that the film connection part of the fourth film supply part 16 is horizontal from the packaging cycle immediately before the packaging cycle in which the film connection parts of the first to third film supply parts 16 simultaneously reach the horizontal seal part. A plurality of packaged articles 12 are continuously discharged out of the system while being held at the discharge position for a period until the packaging cycle immediately after the packaging cycle that has reached the seal portion.

  In the embodiment, the difference between the film drawing lengths of the adjacent rows in the first to fourth film supply units 16 is set to 2 cut pitches, and the film connection portion is located in each row as described above. A total of three packaged products including the packaged products 12 and 12 continuing before and after the packaged product 12 are targeted for discharge as defective packaged products. Therefore, even if defective packaging products in all rows up to the first to fourth film supply units 16 are continuously discharged over a predetermined number of packaging cycles, the number of non-defective products discharged does not increase thereby.

  In each of the cases where the above-described film is finished, after any one of the first to fourth film supply units 16 reaches the horizontal seal position first, all other rows of film connection sites are horizontal sealed. In the period of the number of packaging cycles until the position is reached, the operation of the cutting means 25 in the horizontal sealing means 24 of all the rows can be controlled to pause for a predetermined period. Thereby, in the bag making and filling sections 14 in each row, a packaging cycle in which only the lateral sealing with respect to the film is performed by the lateral sealing means 24 within the same period is performed for a predetermined period, and the plurality of packaging products 12 are not divided. Are discharged as a series of bags. When discharging as a continuous packaging bag, in order not to cause a discharge clogging or the like in the discharging means 30 that rotates the chute 30a, the operation of the cutting means 25 is stopped every other packing cycle to form two continuous bags. Or, it is preferable to make a triple bag every two wrapping cycles, and most preferably, it is discharged as a double bag.

  Further, the number of packaging cycles in which the cutting means 25 temporarily suspends the operation and all or a predetermined period within the same period, or the film joining position where the sticking member is stuck at the film connecting portion is the horizontal sealing means 24. When the horizontal seal position matches the horizontal seal position, the horizontal seal operation by the horizontal seal means 24 may be suspended for the number of packaging cycles. The operation stop of the horizontal sealing means 24 is preferably the stop every 1 to 2 packaging cycles so that it can be discharged as a packaged product 12 having a packaging length of 2 to 3 bags in the same manner as the stop of the cutting means 25, and most preferably This is a pause for every other packaging cycle, and the same effect as the pause of the cutting means 25 can be obtained. Further, by pausing only the packaging cycle in which the horizontal sealing position and the film bonding position match, the sticking member is fused to the sealing surfaces of the sealing bodies 24a and 24a of the horizontal sealing means 24, and seal clogging occurs. It is possible to prevent the occurrence of defective packaging in the packaging cycle.

  As described above, in the embodiment, when the end of the film f in use is detected in any one of the plurality of rows of the film supply units 16, the film connection is performed in the film supply units 16 in all rows at the same time. From the case where the film connection for each row is completed, the number of discharged packaging products 12 that do not include the film connection site together with the defective package product including the film connection site is discharged out of the system as compared with the case where the film connection is performed individually. This can be reduced and productivity can be increased. In particular, in the configuration in which the film drawing length in the path from the film connection position to the horizontal seal portion is different for each row as in the embodiment, the film connection time is changed according to the difference in the film draw length and The film connection portions of the rows can be reached at the same time, and the waste of the number of non-defective products disposed when all the rows of defective packages including the film connection portions are discharged together with the good products can be suppressed. Further, since all the packaged products 12 are discharged out of the system as a set of all the packaged products 12, in a configuration in which a plurality of articles of different varieties are combined and conveyed downstream. It is possible to avoid a situation in which some types of packaged products are transported to a downstream processing machine in a missing state.

  By temporarily suspending the operation of the cutting means 25 and discharging the packaged product 12 including the film connection part as a continuous packaging bag in which a plurality of bags are connected, it can be identified at a glance that it is a defective packaged product. A good product and a good product can be reliably identified. The bag length of the packaged product 12 obtained by suspending the operation of the horizontal sealing unit 24 together with the operation of the cutting unit 25 is doubled or more, and a defective product and a non-defective product can be identified. Further, when the film connection portion matches the horizontal seal position, the horizontal seal is suspended, so that the sticking member is fused to the seal surfaces of the seal bodies 24a and 24a of the horizontal seal means 24, and the seal is clogged. Or the occurrence of defective packaging in the packaging cycle is prevented. Further, the package 12 obtained by transverse sealing and cutting by the transverse sealing means 24 of the vertical bag making and filling machine is discharged out of the system by the chute 30a of the discharging means 30 provided below the bag making and filling section 14. Therefore, the continuous packaging bag including the film connecting portion can be reliably discharged out of the system without being sent downstream from the vertical bag making and filling machine.

(Example of change)
The present invention is not limited to the configuration of the embodiment, and can be modified as follows.
(1) In the embodiment, the vertical bag making and filling machine is exemplified as the bag making and filling machine, but the bag making and filling machine can be applied to other bag making and filling machines such as a horizontal bag making and filling machine.
(2) The number of bag making and filling portions 14 is not limited to the four rows in the embodiment, and can be applied to a device having at least two or more rows of bag making and filling portions.
(3) In the embodiment, the film supply portions 16 provided in each of the plurality of rows of bag making and filling portions 14 are arranged stepwise, and the film drawing lengths extending from the respective film supply portions 16 to the lateral seal portions are different. However, for example, the film guide lengths leading to the bag making and filling unit 14 are made different to set the film drawing lengths in the same row, or the film supply units 16 are arranged side by side at the same position. A configuration in which the drawer lengths are the same may be employed. By doing so, no matter which row consumption of the film is detected, the film f is cut and connected at the same time so that the film connection part reaches the horizontal seal portion at the same time in all rows. Therefore, it is possible to reduce the number of discharges of a set including defective products and minimize waste due to discharge of non-defective products.
(4) The supply of the article may be controlled so as to be stopped in accordance with the timing at which the connection portion of the film f reaches the horizontal seal portion. By doing so, an empty bag package is obtained, and it is easy to distinguish it from non-defective products.
(5) The end portion of the raw fabric roll 34 has a non-uniform edge processing shape due to a manufacturing problem of a film manufacturer. In the embodiment, the film f in use in which consumption of the film f is detected as the most preferable form is cut to connect the film end and the new film start end. If necessary, the cutting of the film f by the terminal cutting means 48 can be omitted when the film supply unit 16 detects the film end, such as the processing shape of the edge of the film f, when the old and new films are connected.
(6) In the embodiment, the cutting means 25 is provided in the horizontal sealing means 24. However, the cutting means 25 separate from the horizontal sealing means 24 is provided below the horizontal sealing position, and the horizontal sealing is performed at the horizontal sealing position. The structure which cut | disconnects the film f after being done can be employ | adopted.
(7) In the embodiment, the period during which the film connection part reaches the horizontal seal portion is calculated as the number of packaging cycles. However, by integrating the transmission pulses from the encoder 40 provided in the feeding means 38, etc. It can be obtained by various other detection means.
(8) In the embodiment, the consumption of the film f is detected by the end of the film f passing through the detection means 42. However, the remaining film thickness is detected by detecting the roll diameter of the raw roll 34 with a sensor. Various methods such as detecting the film consumption based on the form to be obtained and the result obtained by calculating the roll diameter can be adopted. By doing so, the multi-row film supply unit 16 is first consumed. The film supply unit 16 is calculated in advance, and for film cutting and connection with each row having a different film pull-out length in relation to the row, the film connection portion is set for each row so that the film connection portion reaches the horizontal seal portion at the same time in all rows. The operation timing of the end cutting means 48 and the film connecting means 44 can be appropriately controlled.
