A guide roller 64 (in this example, three guide rollers 64a to 64c) is provided, which is disposed on the path of the packaging machine section 51 and guides the band-shaped packaging material Fw to be sent to the packaging machine section 51. The guide roller 64a is provided between the printing device 60 and the packaging machine section 51 so that the printing position applied by the printing device 60 on the strip-shaped packaging material Fw matches the printing position on a predetermined bag in the packaging machine section 51 further downstream. The guide roller 64c functions as a printing adjustment roller that adjusts the length of the strip-shaped packaging material Fw that extends to the packaging material supply section 52. It functions as the first roller that adjusts the

The packaging machine section 51 includes a cylinder former (former) 53 that receives the belt-shaped packaging material Fw guided by the first roller 64c and curves the belt-shaped packaging material Fw into a substantially cylindrical shape; It seals the filling tube 54 into which the product S to be packaged is placed, and both side edge portions of the band-shaped packaging material Fw, which is placed in front of the filling tube 54 and is curved into a substantially cylindrical shape. A vertical sealing device 55 that forms the cylindrical packaging material Ft by using the cylindrical packaging material Ft is disposed below the filling cylinder 54, and is provided with a seal that crosses the cylindrical packaging material Ft in the front-rear direction to prevent the product from being manufactured in advance. A horizontal sealing device 56 seals the head of the packaging bag B into which it is loaded and forms the bottom of the subsequent packaging bag B. A packaging material conveying section 57 is provided which feeds the shaped packaging material Ft downward while sucking it. By operating the vertical sealing device 55, the horizontal sealing device 56, and the packaging material conveying section 57 at mutually timed intervals, bag packages Bp in which products are packaged are continuously manufactured.

The dancer roller section 58 includes a fixed position roller group 65 having a plurality of (three in this example) fixed position rollers 65a to 65c whose arrangement positions are fixed, and two adjacent fixed rollers of the fixed position roller group 65. A moving roller group 66 includes a plurality of (two in this example) moving rollers 66a, 66b that can fit between 65a and 65b and between 65b and 65c, and moving rollers 66a, 66b are connected to comb teeth 68a, 68b. The rotary lever 67 is provided at the tip of the rotary lever 67. Since the band-shaped packaging material Fw is stretched between the fixed position roller group 65 and the movable roller group 66, when the rotation lever 67 is rotated downward as shown by the solid line, the dancer roller section 58 A considerable length of band-shaped packaging material is stored. When the rotation lever 67 is flipped upward as shown by the imaginary line, the strip-shaped packaging material Fw stored in the dancer roller section 58 is supplied toward the packaging machine section 51.

In the packaging material supply section 52, the supply path of the strip-shaped packaging material Fr supplied from the dancer roller section 58 is a vertical feeding path Ws that goes straight from the bottom to the top. The above-described paper splicing device 59, printing device 60, and print inspection device 63 are sequentially arranged along the vertical feed path Ws. The paper splicing device 59 is used to cut the used band-shaped packaging material Fw to form a terminal end, and to connect the old and new band-shaped packaging material Fw. The paper splicing device 59 has a paper splicing table 36 that can be flipped up as shown in the figure, and when splicing the paper, the starting end of a new strip-shaped packaging material is placed on the spliced table 36 that has been flipped up. By arranging the end of the old and new band-shaped packaging material so that they are butt-matched, and pasting a paper splicing tape over both ends of the new and old band-shaped packaging material, it is possible to join the old and new band-shaped packaging materials.

Information contents that do not change depending on the lot of the manufactured bag packaging body Bp, such as the manufacturing material and content of the product S, are printed on the strip-shaped packaging material Fw by printing in advance when manufacturing the packaging material roll Fr. . However, in the case of information contents that change from time to time, such as manufacturing date and time, expiration date, etc., such information may be stored in the form of a strip in the process of being supplied, in accordance with the actual packaging of the product S by the bag-forming-fill-sealing machine 50. The printing device 60 directly prints on the packaging material Fw. The display printed on the strip-shaped packaging material Fw appears on the outer surface of the bag package Bp in which the product S is packaged, so that consumers and the like can confirm the display content. The printing machine 61 of the printing device 60 is disposed on one side (front side; outside of the bag packaging body Bp) of the strip-shaped packaging material Fw, and prints actual packaging information such as manufacturing date and time and expiration date on the passing strip-shaped packaging material Fw. Print out the information at the time. An anvil 62 that serves as a backing for printing on the strip packaging material Fw by the printing device 61 is arranged at a position close to the strip packaging material Fw and facing the printing machine 61 with the strip packaging material Fw in between.

The quality of the printing applied to the strip-shaped packaging material Fw is inspected by the printing inspection device 63. The print inspection device 63 includes an inspection main body 63a and an inspection background plate 63b disposed opposite to the inspection main body 63a with the strip-shaped packaging material Fw in between. For example, if the region of the strip-shaped packaging material Fw to which printing is applied is a transparent film portion, when the inspection main body 63a photographs the printing on the strip-shaped packaging material Fw, external light passes through the transparent film portion and is inspected. The main body 63a is obliquely entered, and the external background is reflected, causing trouble in inspecting the quality of printing. Therefore, in order to prevent external light from entering the inspection body 63a, an inspection background plate 63b is provided at a position facing the inspection body 63a with the strip packaging material Fw in between.

In the packaging material supply section 52, among the guide rollers 64 that are disposed further downstream of the print inspection device 63 and guide the strip-shaped packaging material Fw, the guide roller 64a is made vertically variable, so that the strip-shaped packaging material Fw is The length of the path taken to reach the packaging machine section 51 can be changed. As a result, the length of the strip-shaped packaging material Fw from the printing device 60 to the packaging machine section 51 can be adjusted, so there is no need to change the installation position of the printing device 60 in the packaging material feeding direction on the vertical feeding path Ws. Also, in the band-shaped packaging material Fw that is sent to the packaging machine section 51 and formed into a packaging bag B, the printing position printed by the printing device 60 and the registration mark position applied to each bag of the band-shaped packaging material Fw are determined on the packaging bag. It is possible to match the specifications of B. Thereafter, the strip-shaped packaging material Fw is fed into the packaging machine section 51 via a transverse feed path Wh formed by two guide rollers 64b and 64c.

The cross-feed path Wh is the final supply portion of the packaging material supply section 52, and is provided in the connection space Sc where the packaging material supply section 52 is connected to the packaging machine section 51. The position of the guide roller 64c on the most downstream side can be changed in the longitudinal direction of the lateral feed path Wh, as shown by the imaginary line. By changing its position, the guide roller 64c (first roller) adjusts the feeding angle θ of the belt-shaped packaging material Fw to the cylinder making machine 53 to the optimum angle for bending the belt-shaped packaging material Fw in the cylinder making machine 53. Adjust to.

Patent Document 1 discloses that a printing device prints the manufacturing date and expiration date on a fed-out sheet, and a printing inspection device consisting of a television camera is disposed downstream of the printing device in the sheet feeding direction, and the printing device prints the There has been disclosed a filling and packaging device that images the written characters with a television camera, compares and analyzes the imaged character pattern with a character pattern registered in advance in a print inspection device, and activates a warning device in the case of nonconformity.

In the conventional bag-forming-fill-sealing machine 50 as described above, when the product S (item) to be packaged is changed, when the strip-shaped packaging material is cut at the position of the paper splicing table 36 of the paper splicing device 59, the strip-shaped packaging material is cut. The discarded length of the material is the length that remains and extends from the cut position of the paper splicing table 36 to the end of the packaging machine section 51. In particular, when the paper splicing device 59 is disposed at a position upstream of the dancer roller section 58 and immediately downstream of the packaging material roll holding section 69, the waste length of the strip-shaped packaging material Fw produced during paper splicing is This includes the length stored in the dancer roller section 58, making it even longer. Furthermore, when setting a new strip-shaped packaging material in the packaging material supply section 52, the work of passing the strip-shaped packaging material through the dancer roller section 58, the printing device 60, and the printing inspection device 63 is complicated and troublesome because it has to pass through a narrow gap. It's a lot of work. Therefore, a new belt-shaped packaging material to be used next is spliced on the paper splicing table 36 to the belt-shaped packaging material used up until then, and pulled to the front of the cylinder forming device (former) 53 of the packaging machine section 51. It is common practice to thread a new strip of packaging material through the tube after replacing the tube (usually with a different diameter). This kind of work has problems in that it is difficult and labor-intensive to thread the band-shaped packaging material, and that the length of the band-shaped packaging material becomes long as it is lost (wasted).

It is an object of the present invention to provide a bag making, filling and packaging machine equipped with a printing device and a printing inspection device.

In order to solve the above problems, a bag making, filling and packaging machine equipped with a printing device and a printing inspection device according to the present invention has the following features:
a printing device disposed along the supply path of the strip-shaped packaging material and for printing on the strip-shaped packaging material; and a printing device disposed downstream of the printing device in the supply direction of the strip-shaped packaging material for printing on the strip-shaped packaging material; a packaging material supply unit having a print inspection device that inspects the print;
Bag packaging bodies are continuously manufactured by sequentially repeating the steps of manufacturing a packaging bag from the band-shaped packaging material supplied from the packaging material supply unit, storing a product in the packaging bag, and sealing the packaging bag containing the product. It is equipped with a bag making, filling and packaging machine section that manufactures bags according to
The printing device includes a printing machine that prints on the front side of the band-shaped packaging material, and a backing plate for printing on the band-shaped packaging material performed by the printing machine, and is arranged opposite to the printing machine with the band-shaped packaging material in between. It has an anvil,
The printing inspection device includes an inspection body that is disposed close to one side of the strip-shaped packaging material and that inspects the printing on the strip-shaped packaging material, and an inspection body that prevents external light from entering the inspection body. and an inspection background plate disposed on the opposite side of the inspection body across the strip packaging material in order to prevent There it is,
The anvil is movable between a facing position when the anvil occupies the backing against the printing machine and a separation position when the anvil is away from the printing machine,
The inspection background plate is movable between an opposing position when it is disposed close to the strip-shaped packaging material and facing the inspection body, and a separation position when it is away from the inspection body. It is possible and
The bag making, filling and packaging machine is covered with a cover body,
A part of the cover body corresponding to the printing device is configured as an opening/closing door that opens toward the outside of the cover body,
The anvil is provided inside the opening/closing door, and when the opening/closing door is closed, the anvil occupies the opposing position, and when the opening/closing door is opened, the anvil moves toward the separating position and moves toward the opening/closing door. consists of moving together .

According to this bag making, filling and packaging machine equipped with a printing device and a printing inspection device, in the printing device, the anvil occupies an opposing position when placed facing each other as a backing when the printing device prints on a strip-shaped packaging material. Since the anvil is movable between the position where the anvil and the printing machine are separated from each other in a direction in which it is wider than when it is in the facing position, when the anvil occupies the facing position, the anvil is able to move between As a backing, the printing machine can print on the strip-shaped packaging material. When the anvil occupies the away position, it is separated from the printing machine in a wider direction than when it occupies the opposing position, and a sufficient distance is formed between the anvil and the printing machine, so that It becomes easy to pull out the strip-shaped packaging material from the printer and to route the strip-shaped packaging material in front of the printing machine. Moreover, when the anvil occupies the separated position, it becomes easy to access the printing machine and the anvil through a sufficient distance, and maintenance work such as inspection and repair of the printing apparatus can be easily performed. In addition, regarding the printing inspection device, the inspection main body that inspects the printing on the strip-shaped packaging material is placed close to one side of the strip-shaped packaging material, and the inspection background plate is placed between the strip-shaped packaging material and inspected. It is located on the opposite side of the main body. The inspection background board has two opposing positions: one in the opposing position when it is placed close to the strip-shaped packaging material and facing the main body of the test, and the other in the opposite position when the distance from the main body is wider than when it is in the facing position. Since the inspection background plate is movable between the two positions, when the inspection background plate occupies the opposing position, the inspection background plate acts as a shielding plate that blocks external light from entering the inspection body when the inspection body inspects the print. The inspection main body can inspect the printing on the strip-shaped packaging material without being disturbed by external light. When the inspection background plate occupies the separated position, a sufficient gap is formed between the inspection background plate and the inspection body, so it is necessary to pull out the strip packaging material from the gap and insert the strip packaging material into the sufficiently wide gap. It becomes easier to insert. In addition, when the inspection background plate occupies the separated position, the inspection body and the inspection background plate are sufficiently far apart, so that the inspection body and the inspection background plate can be accessed through the sufficient distance when maintenance of the print inspection device is performed. It becomes easier to do.
Furthermore, according to the bag making, filling and packaging machine equipped with this printing device and printing inspection device, the bag making, filling and packaging machine is covered with a cover body, and a part of the cover body corresponding to the printing device is outside the cover body. The anvil is provided inside the opening/closing door, and when the opening/closing door is closed, the anvil occupies the opposing position, and when the opening/closing door is opened, the anvil is placed in the separating position. It can be moved towards the printer along with the opening/closing door to increase the distance between it and the printing machine.

In this bag making, filling and packaging machine equipped with a printing device and a printing inspection device, the direction in which the anvil starts moving from the opposing position toward the separation position is a direction in which it moves away from the printing device while facing the printing device. can do. According to the bag making, filling and packaging machine equipped with this printing device, the direction in which the anvil starts moving away from the facing position is the direction in which it moves away from the printing machine while facing it, that is, perpendicular to the printing front of the printing machine. Therefore, the movement of the anvil in the direction away from the printing machine is efficient, and the gap between the anvil and the printing machine can be efficiently widened.

In this bag making, filling and packaging machine equipped with a printing device and a printing inspection device, the opening/closing door has a rectangular window frame surrounding a transparent window, and either the left or right side of the window frame is It may be hinged to the cover body. Since the opening/closing door is hinged to the cover body at either the left or right side, the opening/closing door can be opened and closed in the same manner as opening and closing a normal door.

In this bag making, filling and packaging machine equipped with a printing device and a printing inspection device, the supply of the strip-shaped packaging material from the packaging material supply section to the bag making, filling and packaging machine section is connected to the bag making, filling and packaging machine section. The strip-shaped packaging material is guided in the lateral direction by two guide rollers spaced apart from each other in the feeding direction of the strip-shaped packaging material in the connection space of the packaging material supply section, through a lateral feeding path defined; The print inspection device may be disposed closer to the guide roller on the upstream side in the lateral feed path. According to the bag making, filling and packaging machine equipped with this printing device and printing inspection device, the path for supplying the strip packaging material from the packaging material supply section to the bag making, filling and packaging machine section is connected to the bag making, filling and packaging machine section. This is a path passed through the connection space of the packaging material supply section, and this path is a lateral feed defined to guide the strip packaging material laterally by two guide rollers spaced apart in the feeding direction of the strip packaging material. It is a route. Since the print inspection device is placed along the horizontal feeding path, it is only necessary to install the printing inspection device so as to face the strip-shaped packaging material passing through the horizontal feeding path, which not only simplifies the installation work but also makes the printing inspection device It is also advantageous for maintenance. Moreover, since the print inspection device is placed closer to the upstream guide roller in the horizontal feed path, the downstream guide roller is moved horizontally to adjust the feeding angle to the bag making, filling and packaging machine section. Even if the position is changed, there will be no interference with the guide roller on the downstream side.

In the bag making, filling and packaging machine which is equipped with this printing device and a printing inspection device and in which the printing inspection device is disposed on a lateral feeding path, the inspection background plate of the printing inspection device is configured to support the rotation of the upstream guide roller. By rotating around the axis, it can be moved to the separated position. According to this bag-forming-fill-sealing machine, the inspection background plate is rotated around the rotation axis of the guide roller on the upstream side, so the rotation axis of the guide roller is also used to rotate the inspection background plate. This allows the structure to be simplified. In addition, the operator can raise and lower the inspection background board with one hand and handle the strip packaging material with the other hand, thereby improving the workability of opening and closing the inspection background board and threading the strip packaging material.

In the bag making, filling and packaging machine which is equipped with this printing device and a printing inspection device and in which the printing inspection device is disposed on a lateral feeding path, the inspection background plate of the printing inspection device is attached to the strip-shaped package fed through the lateral feeding path. The separated position occupied by the inspection background plate of the print inspection device can be a position slid back from the opposing position while maintaining a facing attitude with respect to the inspection main body. According to this bag-forming-fill-sealing machine, the inspection background plate of the print inspection device is placed above the strip-shaped packaging material that is sent along the transverse feed path, and the inspection background plate maintains a facing attitude toward the inspection body from the opposing position. However, by sliding the belt-shaped packaging material further upward, the separation position is reached. Since the inspection background board is slid back from the opposing position, the operator can, for example, hold the inspection background board with one hand and lift it up and down, and use the remaining hand to remove or insert the band-shaped packaging material. The work of opening and closing the plate and threading the band-shaped packaging material can be done easily, improving work efficiency.

In a bag making, filling and packaging machine that is equipped with this printing device and a printing inspection device, and in which the printing inspection device is arranged in a traversal path, the inspection background board that has been moved to the separation position is moved by the weight of the inspection background board, It can be biased in the direction of sliding toward the opposing position and returning. According to this bag-forming-fill-sealing machine, the inspection background plate that has been moved to the separation position by the slide is urged to slide in the direction of descending toward the opposing position due to its own weight, so that it moves to the separation position. By letting go of the inspected background plate, the inspected background plate can be naturally returned to the facing position.

In this bag-forming-fill-sealing machine equipped with a printing device and a printing inspection device, the supply path of the strip-shaped packaging material is such that the strip-shaped packaging material is vertically unwound from a packaging material roll around which the strip-shaped packaging material is wound. The printing device and the printing inspection device can be arranged along the longitudinal feeding path, and the printing inspection device can be arranged immediately downstream of the printing device. According to this bag-forming-fill-sealing machine, the printing device and the printing inspection device are arranged in the vertical feeding path included in the supply path of the strip-shaped packaging material in the packaging material supply section, and the printing inspection device is located directly next to the printing device. Since it is located downstream, the space for arranging the print inspection device can be made as compact as possible, and the print inspection device can immediately inspect the print made by the printing device.

In the bag making, filling and packaging machine which is equipped with this printing device and a printing inspection device and in which the printing inspection device is disposed on a vertical feeding path, the inspection background plate of the printing inspection device is rotated around a pivot shaft. By this, it is possible to move to the separation position. According to this bag-forming-fill-sealing machine, the inspection background plate can be moved to the separation position by rotating around the rotation support shaft, so there is a rotation support between the printing device and the print inspection device. There is no need to provide a space for arranging the shaft, and it becomes possible to arrange the inspection background board close to the printing device. Further, when the inspection background board is in the separated position, it does not interfere with the operator's access to not only the inspection body but also the printing device.

In a bag making, filling and packaging machine that is equipped with this printing device and a printing inspection device and in which the printing inspection device is arranged on a vertical feeding path, the separated position occupied by the inspection background plate of the printing inspection device is moved from the opposite position to the It can be set to a slidable backward position while maintaining a facing attitude toward the test body. According to this bag-forming-fill-sealing machine, the inspection background board occupying the facing position can be slid backward and moved to the separation position while maintaining the facing position. Since the inspection background plate slides back while remaining in the facing position, it is possible to place the inspection background plate immediately downstream and close to the printing device, and when the inspection background plate is in the separated position, the operator can There is no problem in accessing not only the inspection body but also the printing device.

In a bag making, filling and packaging machine that is equipped with this printing device and a printing inspection device and in which the printing inspection device is rotatably supported around a pivot shaft, the inspection background plate that has been moved to the separation position is Due to its own weight, it can be urged to rotate around the rotation support shaft in the direction returning toward the opposing position. According to this bag-forming-fill-sealing machine, the inspection background plate, which has been rotated around the pivot shaft and moved to the separated position, is rotated back toward the opposing position by the weight of the inspection background plate. Since the inspection background plate is moved to the separated position, by releasing the hand from the inspection background plate, the inspection background plate can be naturally returned to the facing position. When the vertical feeding path is a path for feeding the band-shaped packaging material from the bottom to the top, the pivot shaft can be provided at the downstream (upper) end of the path.

In this bag making, filling and packaging machine equipped with a printing device and a printing inspection device, the packaging material supply section includes a dancer roller capable of storing the band-shaped packaging material fed out from the packaging material roll around which the band-shaped packaging material is wound. and a paper splicing device that is disposed along the feeding route of the strip packaging material and is used when joining old and new strip packaging materials, and the paper splicing device is connected to the strip-shaped packaging material rather than the dancer roller section. It can be arranged at a position downstream in the direction of feeding of the packaging material and upstream of the printing device in the direction of feeding of the strip-shaped packaging material. According to this bag-forming-fill-sealing machine, by arranging the paper splicing device downstream of the dancer roller section in the feeding direction of the strip-shaped packaging material, when the paper splicing device connects the old and new strip-shaped packaging materials, the dancer The new band-shaped packaging material is pulled out to the roller section, and the old band-shaped packaging material that remains downstream of the splicing device and will be discarded when switching the band-shaped packaging material is stored in the dancer roller section. Since it does not include a band-shaped packaging material, the amount of waste can be reduced.

According to the bag making, filling and packaging machine equipped with this printing device and printing inspection device, in the printing machine , the anvil has an opposing position as a position to be occupied as a backing when printing on a strip-shaped packaging material by the printing machine, It is movable between a separated position in which the distance from the printing machine is wider than when it occupies the opposing position . Therefore, when the anvil occupies the facing position, the anvil is placed opposite the printing machine and serves as a backing during printing, so that the printing machine can print on the strip-shaped packaging material. When the anvil occupies the away position, it moves in a wider direction and away from the printing machine than when it occupies the facing position, so a sufficient gap is formed between the anvil and the printing machine, and the printing You can easily pull out the strip packaging material from the front of the machine or load the strip packaging material into the front of the printing machine, and it also makes it easy to access the printing machine and anvil, making it easy to inspect and repair the printing device. Maintenance work such as this can be easily performed. In addition, in the printing inspection device, the inspection main body that inspects the printing on the strip-shaped packaging material is disposed close to one side of the strip-shaped packaging material, and the inspection background plate is placed between the strip-shaped packaging material for inspection. The inspection background plate is placed on the opposite side of the main body, and is movable between a facing position where it is close to the strip packaging material and facing the test main body, and a remote position where the distance from the test main body is widened. It is. Therefore, when the inspection background plate occupies the opposing position, the inspection background plate acts as a shielding plate that blocks external light from entering the inspection body when the inspection body inspects the print, and the inspection body is not disturbed by external light. It is possible to inspect the printing on the band-shaped packaging material without any trouble. When the inspection background plate occupies the separated position , a sufficient gap is formed between the inspection background plate and the inspection body, so it is possible to pass the strip-shaped packaging material through the narrow gap between the inspection body and the inspection background plate. This eliminates the need for additional work, making it easier to pass the strip-shaped packaging material through the sufficiently wide gap, improving the workability of pulling out or inserting the strip-shaped packaging material from the gap, and passing the inspection body through the wide gap. This makes it easy to access the inspection background board and the inspection background board, making it easy to perform maintenance work such as inspection and repair of the inspection body.
Furthermore, according to the bag making, filling and packaging machine equipped with this printing device and printing inspection device, the entire bag making, filling and packaging machine is covered with a cover body from the viewpoint of hygiene and safety, and the printing device on the cover body is A part of the cover including the area corresponding to the area is configured as an opening/closing door that opens toward the outside of the cover body, and the anvil is provided inside the opening/closing door, so when the opening/closing door is closed, the anvil is in the opposite position. When the opening/closing door is opened, the anvil moves toward the outside position together with the opening/closing door, and the distance from the printing machine is adjusted to the extent that it is easy to carry out the work of routing the strip-shaped packaging material or the maintenance work of the printing device. It can be unfolded and furthermore, in this separated position, access to the anvil unit and to the printing machine remaining inside the cover body is facilitated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a bag making, filling and packaging machine equipped with a printing device and a printing inspection device according to the present invention will be described based on the attached drawings. FIG. 1 is a diagram showing an embodiment of a bag making, filling and packaging machine equipped with a printing device and a printing inspection device according to the present invention, and the bag making, filling and packaging machine is a vertical type bag making, filling and packaging machine. In this embodiment, the present invention will be explained as a vertical bag-forming-fill-sealing machine, but it may also be a bag-forming-fill-sealing machine such as a horizontal bag-forming-fill-sealing machine.

A bag making, filling and packaging machine (hereinafter abbreviated as "packaging machine") 10 equipped with a printing device and a printing inspection device according to the present invention is basically, for example, a conventional bag making, filling and packaging machine 50 shown in FIG. It has a similar configuration. That is, the packaging machine 10 sequentially repeats manufacturing the packaging bag B from the strip-shaped packaging material Fw, storing the product S in the packaging bag B, and sealing the packaging bag B containing the product S, thereby creating the bag packaging body Bp. It includes a bag-forming-fill-sealing machine section (hereinafter abbreviated as "packaging machine section") 11 that continuously produces bags, and a packaging material supply section 12 that supplies strip-shaped packaging material Fw to the packaging machine section 11. The basic configurations of the packaging machine section 11 and the packaging material supply section 12 are the same as those of the packaging machine section 51 and the packaging material supply section 52 of the bag making, filling and packaging machine 50 shown in FIG. Components that are the same as those used in FIG. 9 are designated by the same reference numerals as those used in FIG. 9, and detailed explanation thereof will be omitted.

The packaging material supply section 12 of the embodiment shown in FIG. 1 is provided with a printing device 60 that prints on the strip-shaped packaging material Fw on the vertical feeding path Ws of the strip-shaped packaging material Fw, as in the conventional packaging machine. As in the case of the conventional bag-filling-packaging machine 50, the printing device 60 is connected to a printing device 61 that prints on the front side of the strip-shaped packaging material Fw that passes through the placement position, and a printing device 61 that is connected to the printing device 61 across the strip-shaped packaging material Fw. It has an anvil 62 which is arranged opposite to each other and serves as a backing for printing on the band-shaped packaging material Fw. The detailed configuration of the printing device 60, particularly regarding the anvil, will be described below based on the descriptions of FIGS. 2 to 4.

The printing position on the strip-shaped packaging material Fw is determined in the width direction W of the strip-shaped packaging material Fw according to the specifications of the packaging bag B to be manufactured, and in the same way, the printing position on the strip-shaped packaging material Fw is determined depending on the length of the packaging bag B in the feeding direction of the strip-shaped packaging material Fw. It is determined according to the specifications of packaging bag B, including the size. Therefore, the printing position in the feeding direction on the strip-shaped packaging material Fw generally differs for each strip-shaped packaging material Fw used for packaging. In order to cope with this, changing the installation position of the printing device 60 itself to the feeding direction of the strip-shaped packaging material Fw is a complicated operation. Therefore, by changing the path length of the strip-shaped packaging material Fw from the location of the printing device 60 to the packaging machine section 51 without changing the installation position of the printing device 60 in the packaging material supply section 52, the strip-shaped packaging material It is possible to deal with differences in printing position for each Fw.

In the packaging material supply section 52, a guide roller 64 around which the band-shaped packaging material Fw is wound is provided on the downstream side of the printing device 60. The arrangement position of the guide roller 64a on the most upstream side among the guide rollers 64 can be changed in the vertical direction, which is an extension of the vertical feed path Ws, as shown by the arrow. By making the arrangement position of the guide roller 64a changeable, the length of the supply path of the strip-shaped packaging material Fw from the arrangement position of the printing device 60 to the packaging machine section 11 can be adjusted. By adjusting the length of the supply path of the strip-shaped packaging material Fw, the printing device 60 can pass in front of the strip-shaped packaging material without changing the installation position of the printing device 60 in the packaging material feeding direction in the packaging material supply section 12. When printed on Fw, in the packaging bag B manufactured from the strip-shaped packaging material Fw sent to the packaging machine section 11, the printing will be in line with the registration mark position applied to each bag of the strip-shaped packaging material Fw. Similarly, it can be assumed that the packaging bag B is placed correctly at a position determined by its specifications.

The most downstream guide roller 64c of the guide rollers 64 is arranged in the lateral direction as shown by the arrow, that is, in the direction of approaching and separating from the guide roller 64b (in other words, the direction in which the strip-shaped packaging material is moved along the lateral feeding path Wh). feed direction). By making the arrangement position of the guide roller 64c adjustable in the lateral direction, the feeding angle θ of the strip-shaped packaging material Fw fed from the guide roller 64c to the tube-making device 53 can be adjusted so that the strip-shaped packaging material Fw is approximately cylindrical in the tube-making device 53. It can be adjusted to the optimal angle for bending.

FIG. 2 is a perspective view of a cover body that covers the bag making, filling and packaging machine shown in FIG. 1. Further, FIG. 3 is a diagram showing an open state of the opening/closing door in the bag making, filling and packaging machine shown in FIG. 2, and shows the inspection door 2 in the open state placed in front. As shown in Fig. 2, as a hygiene and safety measure especially when the product to be packaged (indicated by the symbol S in Fig. 1) is food, the entire packaging machine is assembled with, for example, a transparent acrylic plate. It is housed in a box-shaped cover body 1 consisting of: An input port 9 of a hopper provided above a filling cylinder (indicated by reference numeral 54 in FIG. 1) opens in the ceiling wall 31 of the cover body 1. The packaging material roll Fr of the packaging material supply section 52 is loaded in an open state into a roll holder 34 that is cantilever-supported by an arm 33 on the back wall 32 of the cover body 1. A paper splicing device 59 is provided inside the cover body 1 so as to be able to swing around a rotation shaft 35 (the direction of swing is indicated by an arrow in FIG. A cut groove 37 is formed to extend laterally. In order to allow the operator to access the splicing device 59 from the outside, a suitable door can be provided on the back wall 32 for the splicing device 59 so that it can be opened and closed.

As shown in FIGS. 2 and 3, the cover body 1 also covers the packaging material supply section 52 that supplies the strip-shaped packaging material Fw fed out from the packaging material roll Fr to the packaging machine section 51, and the back surface of the cover body 1 In the wall 32, a part of the area above the paper splicing device 59 is an inspection door 2 having a transparent window 3 surrounded by a rectangular window frame 2a. The operator can visually observe the packaging material supply unit 52 disposed inside the cover body 1 through the transparent window 3. The inspection door 2 is attached to the left side of the window frame 2a so that it can be opened and closed by rotating with a hinge 2b, and a handle 7 is provided on the right side of the window frame 2a for opening and closing the inspection door 2. ing. When the inspection door 2 is closed, the rear wall 32 can be kept airtight. In FIG. 2, the inspection door 2 in the closed state is shown with a solid line together with the anvil unit 4, and the inspection door 2 in the state opened toward the outside of the rear wall 32 by rotation on the hinge 2b is shown as an anvil unit. 4 and is shown in imaginary lines.

In the packaging material supply section 52 in the cover body 1, a vertical feeding path Ws (see FIG. 1) for vertically supplying the strip-shaped packaging material Fw upward is provided along the back wall 32. A printing device 60 and a printing inspection device 63 are arranged along the vertical feed path Ws, and the printing device 60 is arranged close to the strip-shaped packaging material Fw on the back side of the strip-shaped packaging material Fw and passes in front of the strip-shaped packaging material Fw. The present invention includes a printing machine 61 that prints on the front side of the strip-shaped packaging material Fw, and an anvil 6 that is disposed close to the front side of the strip-shaped packaging material Fw extending along the vertical feed path Ws. The anvil will be described hereinafter as an anvil 6 of an anvil unit 4 that is provided as a unit to be attached to the inside of the inspection door 2.

When the inspection door 2 is open, the printing machine 61 and the printing inspection device 63 remaining inside the cover body 1 can be seen through the opening. Since the inspection door 2 opens to the outside of the cover body 1, it does not interfere with the packaging material supply section 52. When the printing machine 61 prints on the strip-shaped packaging material Fw, when the inspection door 2 is closed, the anvil unit 4 is placed in a position directly facing the printing machine 61 with the strip-shaped packaging material Fw in between. is essential. In order to make it possible to change the printing position on the strip-shaped packaging material Fw, the printing machine 61 is movable in the width direction W of the strip-shaped packaging material Fw. This movement of the printing machine 61 is normally performed manually or automatically by a printing machine moving mechanism (not shown) so that the printing machine 61 is moved to a position set by a control device based on the printing specifications of the packaging bag and the like.

The anvil unit 4 includes a substantially box-shaped holder 5 and a mat-shaped anvil 6 attached to the holder 5. Like the conventional anvil 62, the anvil 6 serves as a backing for printing on the strip-shaped packaging material Fw performed by the printing machine 61, and is used as a backing against the impact (impact force) generated when the printing machine 61 prints on the strip-shaped packaging material Fw. It has a material and thickness that can absorb the damage. The inspection door 2 is appropriately locked by a lock 7 which also serves as a handle 7 so that it does not open unexpectedly when it is closed.

As shown in FIG. 3, a moving mechanism 20 is provided that allows the anvil unit 4 to be moved in the width direction W of the strip-shaped packaging material Fw (with the inspection door 2 closed). The moving mechanism 20 includes two parallel guide rods 21, 21, and both ends of the guide rods 21, 21 are attached to supports 8, 8 provided inside the window frame 2a of the inspection door 2. There is. The holder 5 is formed with two parallel guide holes 22, 22, and the guide rods 21, 21 are fitted into the guide holes 22, 22, so that the holder 5 is connected to the guide rods 21, 21. You will be guided along the In order to smoothly move the holder 5, a sleeve (not shown) that can slide smoothly on the guide rods 21, 21 can be appropriately attached to the guide holes 22, 22.

The moving mechanism 20 that moves the holder 5 further includes a motor 24 as a drive source provided on the inspection door 2, and a screw mechanism 25 that converts the rotational output of the drive source into linear movement. The screw mechanism 25 includes a screw shaft 26 whose axis extends parallel to the guide rod 21, and a nut 27 that is provided on the holder 5 and is screwed onto the screw shaft 26. Both ends of the screw shaft 26 are rotatably supported by bearings on support portions 8 provided at appropriate locations on the inspection door 2 . The holder 5 is formed with a through hole through which the screw shaft 26 passes. The nut 27 is fixedly attached to the holder 5 so as not to move in the axial direction or rotate.

The moving mechanism 20 further includes a chain 30 that is wound around a sprocket 28 provided on the output shaft of the motor 24 and a sprocket 29 provided on the screw shaft 26, so that the rotational output of the motor 24 is transmitted to the sprocket 28, The power is transmitted to the screw shaft 26 via a power transmission mechanism including the power transmission mechanism 29 and the chain 30. The power transmission mechanism from the output shaft of the motor 24 to the screw shaft 26 is not limited to the chain 30, but may be a gear or a belt. According to this moving mechanism 20, when the screw shaft 26 is driven by the motor 24, the nut 27 fixedly provided on the holder 5 is moved along the screw shaft 26 together with the holder 5 by the screw feeding action of the screw mechanism 25. . When the inspection door 2 is closed, the guide rods 21, 21 and the screw shaft 26 extend in the width direction W of the strip-shaped packaging material Fw. It is guided in the width direction W.

When the inspection door 2 is closed, the anvil 6 attached to the inspection door 2 is at a facing position P1 (see FIG. 2) directly facing the printing machine 61. At this time, the distance between the printing machine 61 and the anvil 6 is about 3 mm as usual. When the inspection door 2 is in a closed state, even if you attempt to remove the strip-shaped packaging material Fw from the printing device 60, load the strip-shaped packaging material Fw, or perform maintenance work on the printing device 60, the inside of the cover body 1 may be damaged. Since access is not possible, when attempting to perform such work, the inspection door 2 on the rear wall 32 must be opened to ensure access to the inside of the cover body 1.

The operation of opening the inspection door 2 is simultaneously an operation of moving the anvil unit 4 attached to the inspection door 2 away from the printing machine 61. That is, just by opening the inspection door 2 outward, the distance between the printing machine 61 and the anvil unit 4 is greatly increased. Since the inspection door 2 opens while rotating around the hinge 2b, when the anvil 6 begins to move away from the opposing position, it moves away from the state where it was directly facing the printing machine 61 in a direction orthogonal to the rear, increasing the gap. The operation becomes efficient. The separation position P2 of the anvil 6 (see FIGS. 2 and 3) is set to such an extent that the operator can easily remove and load the strip packaging material Fw or perform maintenance work on the printing device 60, for example, the inspection door 2 is at a 90 degree angle. The position can be set to a position where there is a sufficient distance from the printing machine 61. At the separated position P2, not only the anvil unit 4 can be easily accessed, but also the printing machine 61 remaining inside the cover body 1 can be easily accessed.

When the operator completes the above-mentioned work, the inspection door 2 is closed. The anvil unit 4 attached to the inspection door 2 returns to the facing position P1 directly facing the printing machine 61 when the inspection door 2 is closed against the rear wall 32. The gap between the printing device 61 of the printing device 60 and the anvil 6 is approximately 3 mm, as in the case of the conventional bag-filling-packaging machine. When loading the strip-shaped packaging material Fw, when the inspection door 2 is closed, the strip-shaped packaging material Fw is simultaneously sandwiched between the small gap between the printing machine 61 and the anvil 6. In this way, by opening and closing the inspection door 2, it is possible to move the anvil 6 to the separation position P2 sufficiently far away from the printing machine 61 and return it to the original facing position P1, so the above-mentioned work is not time-consuming. It becomes work. In this embodiment, when changing the printing position in the width direction W on the strip-shaped packaging material Fw, the printing machine 61 and the print inspection device 63 are moved in the width direction of the strip-shaped packaging material Fw. By moving the band-shaped packaging material Fw in the width direction W by the moving mechanism 20, the position facing the printing machine 61 can be maintained.

In the anvil unit 4 of this embodiment, the anvil 6 is held replaceably by the holder 5, and the anvil 6 moves together with the holder 5 when the holder 5 is moved. By holding the anvil 6 in the holder 5 so that it can be replaced, in the event that an anvil 6 deteriorates or suffers a problem, the old anvil can be removed from the holder 5 and replaced with a new anvil by attaching it to the holder 5. . The movement of the anvil 6 relative to the printing machine 61 is carried out by the holder 5, and the anvil 6 is not directly involved in the movement, so that an inadvertent influence on the anvil 6 can be avoided.

FIG. 4 shows another example of moving the anvil. FIG. 4A shows an opposing position P1 in which the anvil 6 (together with the holder 5 supporting it) is moved forward and backward to face the printing machine 61 while facing the printing machine 61. This structure moves between the position P2 and the separation position P2, which is retreated from the printing machine 61. A conceivable structure for advancing and retracting is a structure in which a plurality of guide members 42, 42 fixed to the holder 5 are guided through through holes 41, 41 formed in the frame 40 of the packaging material supply section.

In FIG. 4(b), the holder 5 (together with the anvil 6 supported by it) is attached to the arm 43, and the anvil 6 is printed by rotating the arm 43 around a rotation shaft 44 provided in the packaging material supply section. It has a structure in which it moves between a facing position P1 in which it directly faces the printing machine 61 and a separating position P2 in which it moves away from the printing machine 61 by rotating, for example, 90 degrees as shown in the figure. In either case, the direction in which the opening starts from the opposing position P1 to the separating position P2 is the direction in which the opening moves away from the opposing position P1 while facing each other. Since the printing machine 61 and the anvil 6 can be accessed at the separation position P2, operations such as removal and loading of the band-shaped packaging material Fw, maintenance, etc. are facilitated.

In the packaging machine 10 shown in FIG. In the connection space Sc where the material supply section 12 is connected to the packaging machine section 11, it is arranged along the lateral feed path Wh formed between the guide roller 64b and the guide roller 64c. In the embodiment shown in FIG. 1, the print inspection device is the same as that described as the print inspection device 63, and will be described with reference numeral 16. The print inspection device 16 includes an inspection body 17 disposed below the lateral feed path Wh, and an inspection body 17 disposed on the opposite side of the inspection body 17 across the lateral feed path Wh (on the top side of the strip-shaped packaging material Fw). It has an inspection background plate 18. The inspection main body 17 inspects the print made on the strip-shaped packaging material Fw in close proximity to the lower surface of the strip-shaped packaging material Fw traveling on the transverse feed path Wh. The inspection background plate 18 disposed above the transverse feed path Wh plays a role in preventing external light from entering the inspection main body 17. The printing device 60 is attached to the attachment frame portion 14 of the attachment frame 13, and the print inspection device 16 is attached to the attachment frame portion 15 of the attachment frame 13, respectively.

The print inspection device 16 is located at a location sufficiently downstream from the printing device 60, called the connection space Sc, and basically makes effective use of an existing empty space that has not been used for anything in particular in the past. Therefore, there is no need to prepare an additional arrangement space inside the packaging material supply section 12 just for the arrangement of the print inspection device 16, which was conventionally required. If such additional space is provided, the packaging machine 10 will become taller and larger, but this embodiment can avoid such an increase in size. Moreover, due to the arrangement of the print inspection device 16 in the connection space Sc, other structures of the packaging machine 10 are not substantially affected. Furthermore, the path length of the strip packaging material Fw supplied from the packaging material supply section 12 to the packaging machine section 11 is longer than that of the conventional one, since no space is required for the printing inspection device 16. It is possible to shorten the time by According to the arrangement structure of this embodiment, even in a packaging machine where space for arranging a print inspection device cannot be secured immediately after the printing device 60, there is an empty space along the lateral feed path Wh inside the packaging machine 10. Since the printing inspection device 16 can be placed in an effective manner, the printing performed by the printing device 60 can be inspected inside the packaging machine 10.

FIG. 1(a) shows a state in which the inspection background plate of the print inspection device provided in the bag-forming-fill-sealing machine occupies an opposing position and normal packaging operations are possible. FIG. 1(b) shows a state in which the inspection background plate of FIG. 1(a) occupies a separated position. The inspection background plate 18 is located at an opposing position Q1 (FIG. 1(a)) parallel to the horizontal feeding path Wh, close to the strip-shaped packaging material Fw, and facing the inspection main body 17; It is possible to move between a separation position Q2 (FIG. 1(b)) where the test body 17 springs up and separates from the test body 17, and forms a gap G1 widened between the test body 17 and the test body 17. The inspection background plate 18 is rotatable around an axis coaxial with the rotation axis of the guide roller 64b. For example, if the guide roller 64b is a roller that rotates around a fixed support shaft, the inspection background plate 18 is rotatably supported around the fixed support shaft, and the fixed support shaft is used to control the rotation of the inspection background plate 18. The structure can be simplified by also serving as the rotation shaft 19 for the purpose. The operator can move the inspection background plate 18 between the opposing position Q1 and the separated position Q2 by holding the inspection background plate 18 with one hand and rotating the inspection background plate 18 around the rotation axis 19 by raising and lowering the inspection background plate 18.

When the inspection background plate 18 is at the opposing position Q1, the inspection background plate 18 functions as a shielding plate that prevents external light from entering the inspection body 17 during print inspection by the inspection body 17. The inspection main body 17 can inspect the printing on the strip-shaped packaging material Fw without being disturbed by external light. When the inspection background plate 18 is in the separated position Q2, the inspection background plate 18 is separated from the inspection body 17, and the distance G1 between the inspection background plate 18 and the inspection body 17 is widened to a sufficient distance. When the inspection background board 18 occupies the separation position Q2, the operator pulls out the strip packaging material Fw from the gap G1 with the other hand, inserts the strip packaging material Fw into the gap G1, and prints the strip packaging material Fw. It is possible to easily handle the strip-shaped packaging material Fw by passing it through the inspection device 16, and the workability of passing the strip-shaped packaging material Fw through the inspection device 16 is improved. When the strip-shaped packaging material Fw is pulled out from the gap G1, it becomes easy to access the inspection body 16 and the inspection background plate 17 through the gap G1, and it is also easy to perform maintenance work on the inspection body 17 and the inspection background plate 18. becomes.

Since the inspection background plate 18 is rotatable around the rotation axis 19, the inspection background plate 18 is urged by its own weight to return and rotate around the axis. Therefore, when the operator releases his/her hand from the inspection background plate 18, the inspection background plate 18 naturally returns to the opposing position Q1 by this return rotation. An appropriate stopper can be provided so that the inspection background plate 18 stops at the facing position Q1. By providing some resistance to the rotation of the inspection background plate 18, the force of returning to the facing position Q1 can be alleviated. Since the inspection background plate 18 does not even have an opening/closing locking mechanism, there is no need to release or relock the lock when passing the band-shaped packaging material through.

The strip-shaped packaging material Fw is supplied from the packaging material supply section 12 to the packaging machine section 11 by providing a connection space Sc of the packaging material supply section 12 connected to the packaging machine section 11, and using two guide rollers 64b, 64c. This is carried out through a lateral feed path Wh whose path is defined by . Since the print inspection device 16 is arranged along the horizontal feed path Wh, it is only necessary to install the print inspection device 16 so as to face the strip-shaped packaging material Fw passing through the cross feed path Wh vertically, making the installation work easy. becomes. In addition, since the print inspection device 16 is disposed closer to the upstream guide roller 64b in the horizontal feed path Wh, the downstream guide roller 64c is used to adjust the feeding angle θ to the packaging machine section 11. Even when the position is changed in the horizontal direction (as in FIG. 9, shown by imaginary lines), no interference with the guide roller 64c on the downstream side occurs.

FIG. 5 shows an embodiment of the present invention (indicated by (A) on the right) and a conventional one (indicated by (B) on the left) regarding a bag making, filling and packaging machine equipped with a printing device and a printing inspection device. It is a schematic diagram shown for comparison. In the bag making, filling and packaging machine 10 shown in (A), the packaging machine section is the same as the packaging machine section 11 of the conventional bag making, filling and packaging machine 50 shown in (B), so its description is omitted.

Comparing the length of the strip-shaped packaging material Fw with reference to the position of the paper splicing device 59, the paper splicing of the present packaging machine 10 is compared with the cut height position Hb of the paper splicing device 59 in the conventional bag-filling packaging machine 50. The cut height position Ha of the device 59 is at a position raised by the height difference ΔH due to the movement of the print inspection device 16 to the connection space Sc. Therefore, in the packaging machine 10, the path length of the strip-shaped packaging material Fw sent along the path from the cut height position Ha to the packaging machine section 11 is compared with the path length in the case of the conventional bag-forming-fill-sealing machine 50. It is shorter by the height difference ΔH. When replacing packaging materials or splicing paper, the band-shaped packaging material Fw from the cut position of the paper splicing device 59 to the position of the horizontal sealing device 56 is discarded, resulting in packaging material loss. The path length of the material Fw is shortened by this length, and the amount of packaging material loss that is discarded can be reduced.

Since the print inspection device 16 is not disposed immediately after the printing device 60 in the downstream direction, it does not inspect the print state immediately after printing is performed. However, since the placement positions of the printing device 60 and the printing inspection device 16 can be measured and the path length from the printing device 60 to the printing inspection device 16 can also be calculated, by using an encoder etc., the film can be printed after printing. By calculating the traveling distance, the print inspection device 16 determines the printing state printed by the printing device 60 disposed on the upstream side while controlling the position, timing, and speed of the strip packaging material Fw. can be inspected correctly and at the right time.

Since the front side of the strip-shaped packaging material Fw printed by the printing machine 61 is on the lower side in the cross-feeding route Wh, the print inspection device 16 detects the lower side of the strip-shaped packaging material Fw along the transverse-feeding route Wh of the strip-shaped packaging material Fw. It is placed facing upwards to face the sides. The connection space Sc in which the print inspection device 16 is installed is an empty space that is not used for anything in particular, and the installation posture of the print inspection device 16 is simple so that it faces the horizontal feed path Wh. Therefore, not only the installation work is facilitated, but also the maintenance of the print inspection device 16 is advantageous.

As already explained, the guide roller 64a disposed between the printing device 60 and the printing inspection device 16 has the band-shaped packaging material Fw wrapped around it and can be changed in position in the height direction. The path length of the strip-shaped packaging material Fw that travels between the and the printing inspection device 16 is made variable, and the printing position on the strip-shaped packaging material Fw according to the specifications of the packaging bag B (especially in the feeding direction of the strip-shaped packaging material Fw) is made variable. (Print position as seen) can be changed. By arranging the print inspection device 16 at a position as close as possible to the guide roller 64b arranged upstream of the lateral feed path Wh, the strip-shaped packaging material Fw can be bent into a substantially cylindrical shape as described above. The position of the guide roller 64c can be adjusted in the horizontal direction so as to increase the feed angle θ to the bag making machine 53, and even if the position of the guide roller 64c is adjusted to the upstream side, the print inspection device 16 can This allows you to avoid any interference that may occur.

Corresponding to the winding guidance of the band-shaped packaging material Fw by the guide roller 64a, the printing device 60 and the printing inspection device 16 are directly facing the band-shaped packaging material Fw that has passed around the guide roller 64a, and as a result, the mutual arrangement is It has become close. That is, even if the printing inspection device 16 is located at a far distance from the printing device 60 in terms of the path length of the strip-shaped packaging material Fw, the printing inspection device 16 can be inspected inside the packaging machine 10 by the winding guidance of the guide roller 64a. They occupy positions close to each other with respect to the printing device 60. Further, the printing machine 61 of the printing device 60 is disposed directly facing the front side of the strip-shaped packaging material Fw traveling on the vertical feeding path Ws, and the printing inspection device 16 is arranged directly facing the front side of the strip-shaped packaging material Fw traveling on the horizontal feeding path Wh. It is placed directly facing the front side. That is, the printing device 60 and the printing inspection device 16 are both directly facing the front side (printing side) of the strip-shaped packaging material Fw, and their facing directions are perpendicular to each other.

Since the printing device 60 and the printing inspection device 16 are arranged in such a close and orthogonal relationship, both devices 60 and 16 are further attached to the common mounting frame 13 to form a unit.

FIG. 6 is a diagram showing another embodiment of a bag making, filling and packaging machine equipped with a printing device and a printing inspection device according to the present invention. Fig. 6(a) shows a state in which the inspection background plate of the print inspection device provided in the bag-filling-sealing machine occupies a position opposite to the inspection main body, and normal packaging operation is possible. This shows a state in which the inspection background board occupies a separated position away from the inspection body. A bag making, filling and packaging machine (hereinafter abbreviated as "packaging machine") 70 equipped with a printing device and a printing inspection device shown in FIG. 6 basically has the same configuration as the packaging machine 10 shown in FIG. ing. That is, the packaging machine 70 has a packaging machine section 71 and a packaging material supply section 72 that are similar to the packaging machine section 11 and packaging material supply section 12, except for the structure related to the print inspection device 76, especially the structure for moving the inspection background plate 78. Therefore, these configurations are similar to those of the packaging machine section 51 and the packaging material supply section 52 of the bag making, filling and packaging machine 50 shown in FIG. By assigning the same reference numerals as those used in FIG. 9, detailed explanation will be omitted again. Further, the mounting frame 73 consisting of mounting frame parts 74 and 75 for mounting the printing device 60 and the print inspection device 76 on the machine frame is also similar to the mounting frame 13 and the mounting frame parts 14 and 15 shown in FIG. 1, respectively. .

The print inspection device 76 that inspects the print made by the printing device 60 is disposed along the lateral feed path Wh, as in the previous embodiment, and is disposed below the lateral feed path Wh. There is an inspection main body 77 that inspects the printing on the strip-shaped packaging material Fw traveling on the feeding route Wh, and an inspection body 77 that inspects the printing on the strip-shaped packaging material Fw traveling on the feeding route Wh, and an inspection body 77 that The inspection background plate 78 is disposed on the upper surface side of the Fw and prevents external light from entering the inspection main body 77 during inspection.

In order to move the inspection background plate 78 forward and backward with respect to the inspection main body 77, two parallel guide rods 79, 79 are provided at a position near the guide roller 64b above the lateral feed path Wh. The guide rods 79, 79 are erected on a suitable frame so as to be spaced apart from each other in the direction of the transverse feed path Wh, and each extends in a direction perpendicular to the cross feed path Wh. The inspection background plate 78 is guided by guide rods 79, 79 and is slidable in the vertical direction so as to advance and retreat toward the transverse feed path Wh. The inspection background plate 78 is located at an opposing position Q1 (FIG. 6(a)) which is parallel to the transverse feed path Wh but is located at the lowest position close to the transverse feed path Wh and is disposed opposite to the test main body 77 .

It is. The inspection background plate 88 is rotatable around a pivot shaft 89 disposed on the downstream side thereof, and the operator holds the inspection background plate 88 with one hand and rotates it around the pivot shaft 89. By doing this, the inspection background plate 88 can be moved between the facing position Q1 and the separated position Q2.

When the inspection background plate 88 is in the facing position Q1, the inspection background plate 88 acts as a shielding plate that prevents external light from entering the inspection body 87 when the inspection body 87 inspects the print, and the inspection body 87 blocks the external light. It is possible to inspect the printing on the band-shaped packaging material Fw without being disturbed by it. When the inspection background plate 88 is in the separated position Q2, a sufficiently wide gap G3 is formed between the inspection background plate 88 and the inspection body 87 (or the strip-shaped packaging material Fw adjacent thereto). In this state, the operator can easily handle the strip-shaped packaging material Fw by inserting and removing it through the gap G3 with the other hand, and the efficiency of passing the strip-shaped packaging material Fw through the print inspection device 86 is improved. When the strip-shaped packaging material Fw is pulled out, it becomes easy to access the inspection body 87 and the inspection background plate 88 through the gap G3, and it becomes easy to perform maintenance work on the inspection body 87 and the inspection background plate 88. .

The rotation support shaft 89 is provided at the upper end of the inspection background plate 88 . Therefore, the inspection background plate 88 is urged to rotate around the rotation support shaft 89 in a pendulum manner by its own weight. When the operator releases his hand from the inspection background plate 88, the inspection background plate 88 naturally returns to the facing position Q1 by this return rotation. An appropriate stopper can be provided so that the inspection background plate 88 stops at the facing position Q1. By providing some resistance to the rotation of the inspection background plate 88, the force of returning to the facing position Q1 can be alleviated. Moreover, since the rotation support shaft 89 is disposed so as to extend around the inspection body 87 side of the vertical feed path Ws, a large gap G3 can be provided when the rotation support shaft 89 is at the separation position Q2. Due to this arrangement structure of the rotation support shaft 89, the inspection background plate 88 can be arranged compactly in close proximity to the printing device 60 immediately downstream, and when the inspection background plate 88 occupies the separation position Q2, the inspection background plate 88 can be There is no problem in accessing not only the inspection body 87 but also the printing device 60.
