The printer devices 10A and 10B are each movable between a printing position and a standby position in the width direction P2 of the packaging film F under the control of a control device 9, which will be described later.

Printer device moving mechanism sections 5A and 5B are provided corresponding to the two printer devices 10A and 10B, respectively. The printer device moving mechanism sections 5A and 5B are capable of moving the two printer devices 10A and 10B, respectively, in the width direction P2 orthogonal to the transport direction P1 of the packaging film F. Note that if there is no need to particularly distinguish between the first printer device 10A, the second printer device 10B, and the printer device movement mechanism sections 5A and 5B, they will simply be referred to as "printer device 10 (printing unit)" and "printer device movement mechanism." Part 5”.

The printer moving mechanism section 5 includes a guide rail 51, a moving member 52, and a drive mechanism 53 (see FIG. 2).

As shown in FIGS. 1 to 3, the guide rail 51 is arranged above each of the two printer devices, and is formed in a straight line extending in the left-right direction X of the printer system 1 (width direction P2 of the packaging film F). be done. The guide rail 51 holds the movable member 52 so as to be movable in the width direction P2 (horizontal direction X) of the packaging film F.

As shown in FIGS. 1 and 2, the moving member 52 is attached to the guide rail 51 so as to be movable along the guide rail 51 in the width direction P2 of the packaging film F. The upper part of the printer device 10 is attached to the lower part of the moving member 52. Thereby, the moving member 52 moves in the width direction P2 of the packaging film F, and the printer device 10 also moves in the width direction P2 of the packaging film F.

The drive mechanism 53 is provided on the guide rail 51. The drive mechanism 53 drives the moving member 52 to move along the guide rail 51 in the width direction P2 of the packaging film F. The drive mechanism 53 includes, for example, a ball screw mechanism or a belt mechanism. The drive mechanism 53 is electrically connected to the control device 9. The control device 9 controls the drive mechanism 53 to move the moving member 52 and move the printer device 10 attached to the moving member 52 in the width direction P2 of the packaging film F. Details of the control device 9 will be described later.

As shown in FIG. 3, each of the two printer devices 10A and 10B mainly includes a printer body 20 and a ribbon cassette 30 that is detachably attached to the printer body 20. The ribbon cassette 30 is removably attachable to the printer main body 20. The printer device 10 according to the present embodiment has a so-called cassette-type structure in which the ribbon cassette 30 is detachable from the printer main body 20.

As shown in FIG. 3, the printer main body 20 includes a main body side case body 21 and a thermal head 22 (print head). The main body side case body 21 is formed in a box shape with an opening on the ribbon cassette 30 side.

The thermal head 22 is arranged on the lower side of the main body side case body 21. The thermal heads 22 provided in each of the two printer devices 10A and 10B are arranged at the same inclination angle when viewed from the width direction P2 of the packaging film F, as shown in FIG.

As shown in FIGS. 1 and 3, the thermal head 22 is arranged at the ends of the two printer devices 10A and 10B that are closer to each other. Specifically, the thermal head 22 of the first printer device 10A is arranged on the end side on the second printer device 10B side in the width direction P2 (horizontal direction X) orthogonal to the conveyance direction P1 of the packaging film F, The thermal head 22 of the second printer device 10B is arranged on the end side on the first printer device 10A side in the width direction P2 (horizontal direction X) perpendicular to the transport direction P1 of the packaging film F.

The reason why the thermal head 22 is arranged at the end portions closer to each other in the two printer devices 10A and 10B will be explained. In this embodiment, the details will be described later, but by moving the two printer devices 10A and 10B in the left-right direction X, the printer device used for printing can be switched. When moving the two printer devices 10A, 10B in the left-right direction Compared to arranging the two printer devices 10A and 10B on the far side, the distance to the printing position can be made shorter, and the switching operation can be performed in a shorter time. As a result, the time until the start of the printing operation on the packaging film F is suppressed to the minimum, so that the printing operation is more efficiently prevented from being stopped, and the ability of the printing operation can be improved.

As shown in FIGS. 2 and 3, the thermal head 22 is disposed facing the platen roller 6 with the ink ribbon R and packaging film F interposed therebetween. The thermal head 22 is arranged so that the tip end 22a side protrudes toward the platen roller 6 side. The thermal head 22 is arranged such that the tip end 22a is in contact with the ink ribbon R when the ribbon cassette 30 is attached to the printer main body 20. The thermal head 22 is configured to be movable in the vertical direction by a thermal head pressing mechanism (not shown) when the ribbon cassette 30 is attached to the printer main body 20.

The thermal head 22 includes a plurality of heating elements at its tip 22a. In the thermal head 22, the heating element generates heat when the thermal head 22 is energized. The thermal head 22 prints a print pattern on the packaging film F that is moved in the transport direction P1 when the ribbon cassette 30 is attached to the printer main body 20.

The ribbon cassette 30 is detachably attached to the ends of the two printer devices 10A and 10B that are closer to each other. The ribbon cassette 30 can be attached to and detached from the printer body 20 while the two printer apparatuses 10A and 10B are moved in the left-right direction be.

In the first printer device 10A, the ribbon cassette 30 is removably attached to the end of the first printer device 10A on the second printer device 10B side (X2 side of the first printer device 10A). 10B, the ribbon cassette 30 is removably attached to the end of the second printer 10B on the first printer 10A side (the X1 side of the second printer 10B). The ribbon cassettes 30 of the two printer devices 10A and 10B are located on the side where the thermal head 22 is arranged in the width direction P2 perpendicular to the conveyance direction P1 of the packaging film F in the two printer devices 10A and 10B, respectively. Attached to the end.

As shown in FIG. 2, the ribbon cassette 30 feeds out the ink ribbon R in synchronization with the movement of the packaging film F, which is a printing material that is continuously fed out from a packaging machine (not shown).
As shown in FIG. 3, the ribbon cassette 30 includes a cassette front plate 31, a handle portion 32, an ink ribbon R, and a ribbon transport mechanism (not shown).

The cassette front plate 31 is formed into a plate shape that closes the opening of the printer body 20 when the ribbon cassette 30 is attached to the printer body 20. On the side of the cassette front plate 31 that is closer to each other in the two printer devices 10A and 10B in the left-right direction 32 are provided. The ribbon cassette 30 can be removed from the printer body 20 by grasping the handle portion 32 and pulling the ribbon cassette 30 from the printer body 20. In the two printer devices 10A and 10B, the handle portions 32 are arranged to face each other.

The ink ribbon R is provided in a ribbon transport mechanism (not shown) arranged on the printer main body 20 side of the cassette front plate 31. As shown in FIG. 2, the ink ribbon R is arranged between the thermal head 22 and the printing surface of the packaging film F when the ribbon cassette 30 is attached to the printer main body 20. Ink is transferred from the ink ribbon R to the packaging film F when the thermal head 22 performs a printing operation on the packaging film F. The ink ribbon R is transported (moved) by a ribbon transport mechanism (not shown).

As shown in FIG. 2, the platen roller 6, the upstream conveyance guide roller 71, and the downstream conveyance guide roller 72 are arranged below the printer devices 10A and 10B located at the printing position. The platen roller 6, the upstream conveyance guide roller 71, and the downstream conveyance guide roller 72 guide the movement of the packaging film F in the conveyance direction P1.

The platen roller 6 extends in the width direction P2 perpendicular to the transport direction P1 of the packaging film F. When printing on the packaging film F, the platen roller 6 is disposed facing the thermal head 22 with the ink ribbon R of the printer devices 10A, 10B located at the printing position and the packaging film F interposed therebetween. The platen roller 6 is rotatable with the packaging film F disposed between the platen roller 6 and the thermal head 22 while wrapping at least a portion of the packaging film F around its circumferential surface. Each of the platen rollers 6 is a cylindrical roller with a predetermined outer diameter, and has an elastic layer made of a material having a predetermined elasticity, such as silicone rubber, formed on the circumferential surface of a metal core having a predetermined diameter.

The upstream conveyance guide roller 71 is arranged upstream of the platen roller 6 in the conveyance direction P1 of the packaging film F. The downstream conveyance guide roller 72 is arranged downstream of the platen roller 6 in the conveyance direction P1 of the packaging film F.

The control device 9 will be explained. The control device 9 is electrically connected to the printer devices 10A, 10B and the drive mechanism 53. The control device 9 centrally controls the two printer devices 10A and 10B. The control device 9 controls the thermal heads 22 provided in each of the printer devices 10A and 10B, and controls the movement of the ink ribbon R so that the printer devices 10A and 10B execute printing operations.

The control device 9 controls the drive mechanism 53 of the printer device moving mechanism sections 5A, 5B so as to move each of the two printer devices 10A, 10B in the width direction P2 of the packaging film F. As shown in FIG. 3, the control device 9 controls the printer device moving mechanism units 5A and 5B to position the first printer device 10A at the printing position and position the second printer device 10B at the standby position. Alternatively, as shown in FIG. 4, the printer device moving mechanism sections 5A and 5B are controlled so that the second printer device 10B is located at the printing position and the first printer device 10A is located at the standby position.

With the printer devices 10A and 10B arranged side by side in the width direction P2 of the packaging film F (see FIGS. 3 and 4), the control device 9 controls one of the printer devices 10A and 10B located at the printing position (the printer The device 10A or the printer device 10B) is controlled to execute a printing operation. The control device 9 controls the printer device 10 (printer device 10A or printer device 10B) located at the standby position to stand by as a backup printer device.

For example, as shown in FIG. 3, when the first printer device 10A is performing a printing operation, the first printer device 10A may become inoperable, or the ink ribbon R Maintenance may be required when the thermal head 22 is finished or cut, the thermal head 22 becomes dirty, or malfunctions. In this case, the control device 9 moves the first printer device 10A and the second printer device 10B in the width direction P2 of the packaging film F, as shown in FIG. The printer device 10A is switched to the second printer device 10B, and the second printer device 10B is controlled to execute a printing operation.

Thereby, in the printer system 1, the printing operation can be continued without stopping the printing operation. In the printer device 10A that has been moved to the standby position, when the ink ribbon R is finished or cut, the printer device 10A can be quickly returned to use by replacing the ribbon cassette 30. Furthermore, if the thermal head 22 becomes dirty or malfunctions, the printer device 10A can be quickly restored to use by cleaning the thermal head 22 or replacing the malfunctioning parts. Thereby, maintainability can be improved.

In this way, when the first printer device 10A is performing a printing operation and the first printer device 10A is inoperable or requires maintenance, the transportation of the packaging film F can be done without stopping. By operating the second printer device 10B, which has been on standby without executing the printing operation, in place of the first printer device 10A which is executing the printing operation, for example, packaging film can be printed without stopping the printing operation. F can prevent the production line (packaging line) for packaging products such as foods from stopping.

Similarly, even when the second printer device 10B is performing a printing operation, even if the second printer device 10B is inoperable or requires maintenance, the transportation of the packaging film F can be maintained without stopping. , by operating the first printer device 10A that was on standby without executing a print operation in place of the second printer device 10B that is currently executing a print operation, the manufacturing line ( (packaging line) can be prevented from stopping.

Here, for the purpose of saving ink ribbons, printer devices having, for example, the following ribbon saving function are known.

In a printer device having a ribbon save function, printing using the ribbon save function is performed by using an ink ribbon R having a predetermined width and effectively utilizing a region in the width direction of the ink ribbon R. As shown in FIG. 5A, when printing using the ribbon save function, in the printer device 10, for example, the character strings "AAAA", "BBBB", "CCCC", "DDDD", "EEEE", and "FFFF" are printed on the packaging. This control saves the ink ribbon R in a configuration in which printing is performed in a line at predetermined intervals along the transport direction of the film F.

The ribbon save function saves the ink ribbon R by moving the ink ribbon R in the width direction and rewinding the ink ribbon R to a predetermined length without changing the printing position of the print pattern in the width direction of the packaging film F. This function effectively utilizes the usage area of the ink ribbon R in the width direction to save the usage amount of the ink ribbon R. The ink ribbon R can be moved in the width direction by moving the entire printer device 10 to which the ink ribbon R is attached.

In the ribbon save function, control is performed to feed and rewind the ink ribbon R in the same direction as the traveling direction of the packaging film F, and control is performed to move the ink ribbon R and the thermal head 22 in the width direction of the ink ribbon R. In this case, the ribbon controller rewinds the ink ribbon R by the amount of movement after sending out the ink ribbon R for printing, and also adjusts the width of the ink ribbon R so that the previous use area and the next use area of the ink ribbon R are the same. They are formed at positions lined up in the width direction, and are formed at positions that do not overlap in the direction of movement of the packaging film F.

In the ribbon save function, multiple rows of use areas are formed in the width direction of the ink ribbon R. For example, in this embodiment, in the ink ribbon R, four rows of use areas are formed side by side in the width direction. For example, as shown in (i) to (iv) of FIG. After the ink ribbon R is lined up in order from one side to the other in the width direction and used, as shown in FIG. 5B (v), "EEEE '' are used so as to be lined up in the length direction of the packaging film F, and then used lined up from the other side to one side in the width direction of the ink ribbon R. This control is repeated.

In this way, for example, when printing small characters in the width direction of the ink ribbon R in the transport direction of the packaging film F, the ribbon save function does not change the printing position of the print pattern in the width direction of the packaging film F. In this operation, the unused portion of the ink ribbon R in the width direction is effectively utilized by moving the printer device 10 in the width direction of the packaging film F and rewinding the ink ribbon R by a predetermined length. That is, the printer device 10 having the ribbon saving function includes a moving mechanism that moves the printer device 10 in the width direction of the packaging film F.

In this embodiment, the printing operation is not stopped by moving the two printer devices 10A and 10B in the width direction P2 of the packaging film F using a moving mechanism included in the printer device 10 having a ribbon saving function. Realizes a printing system. As a result, the moving mechanism provided in the printer device 10 having the ribbon saving function can be utilized, so there is no need to newly provide a mechanism for moving the two printer devices 10A and 10B in the width direction P2 of the packaging film F, and the component devices can be simplified.

According to the printer system 1 of this embodiment, for example, the following effects are achieved.
The printer system 1 of the present embodiment includes two printer devices 10A and 10B arranged side by side in the width direction P2 perpendicular to the conveyance direction P1 of the packaging film F, and two printer devices 10A and 10B that are connected to the packaging film F, respectively. One or the other of the two printer devices 10A, 10B is positioned at a printing position, and one or the other of the two printer devices 10A, 10B is positioned at a printing position. The controller 9 includes a controller 9 that controls the printer moving mechanisms 5A and 5B so as to position the other or one of the printers 10A and 10B in a standby position. As a result, by arranging the two printer devices 10A and 10B side by side in the width direction P2 perpendicular to the transport direction P1 of the packaging film F, in a printing system that does not stop the printing operation, interruptions in printing can be suppressed. Space saving in the width direction P2 of the packaging film F can be realized.

Further, the printer system 1 of this embodiment includes one platen roller 6 extending in the width direction P2 orthogonal to the conveying direction P1 of the packaging film F. As a result, in a printing system that does not stop the printing operation, only one platen roller 6 is required, so that it is possible to simplify the apparatus and save space.

Further, in the printer system 1 of the present embodiment, the thermal head 22 of the first printer device 10A is arranged on the end side on the second printer device 10B side in the width direction P2 orthogonal to the transport direction P1 of the packaging film F. The thermal head 22 of the second printer device 10B is arranged on the end side on the first printer device 10A side in the width direction P2 perpendicular to the conveyance direction P1 of the packaging film F, and the ribbon cassettes 30 are arranged on the side of the first printer device 10A. The thermal head 22 is attached to the end of the packaging film F in each of the printer devices 10A and 10B in the width direction P2 on the side where the thermal head 22 is arranged. Therefore, by arranging the thermal head 22 and the ribbon cassette 30 on the ends of the two printer devices 10A, 10B that are closer to each other, the thermal head 22 can be moved when switching between the two printer devices 10A, 10B. The distance to the printing position is shorter than when the two printer apparatuses 10A and 10B are placed on the far side, and switching operations can be performed in a shorter time. As a result, the time required to start printing on the packaging film F is minimized, so printing can be performed without stopping the packaging film F, and the ability of the printing operation can be improved.
