[0012] A first embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a diagram showing the overall configuration of a printer 1 according to the first embodiment. Fig. 2 is a diagram showing a hand-holding unit 14 of the printer 1 according to the first embodiment. Fig. 3 is a diagram showing the structure of the hand-holding unit 14 of the printer 1 according to the first embodiment.

[0013] In the following description and drawings, in this embodiment, the left-right direction in Fig. 1 is referred to as the X direction, one side in the X direction (the right side in Fig. 1) is referred to as the X1 side, and the other side in the X direction (the left side in Fig. 1) is referred to as the X2 side. The up-down direction is referred to as the up-down direction Z, and the width direction of the long film F, which is perpendicular to the X and Z directions, is referred to as the Y direction. The back side in the Y direction (the right side in Fig. 2) is referred to as the Y1 side, and the front side in the Y direction (the left side in Fig. 2) is referred to as the Y2 side.

[0014] The printing device 1 of the first embodiment is incorporated into, for example, a packaging machine (not shown). The printing device 1 prints on a long film F (long body) such as packaging film that is continuously moved by a packaging machine (not shown) or the like. The long film F is transported by a transport control of the packaging machine (not shown) or the like. In this embodiment, the printing device 1 cannot control the transport of the long film F. Note that in this embodiment, a printing device 1 that prints on a long film F (long body) such as packaging film that is continuously moved by a packaging machine (not shown) or the like is described, but the present invention is not limited to this and can also be applied to a printing device that prints on a long film F (long body) such as packaging film that is intermittently moved by a packaging machine (not shown) or the like.

[0015] The long film F is formed from a long film. The long film F is, for example, a packaging film that is moved by a packaging machine (not shown) or the like. The long film F is formed into a long shape, and is introduced into the printing device 1 from outside the system on the upstream side of the printing device 1 (the X2 side in the X direction) by a packaging machine (not shown) or the like that is arranged outside the system of the printing device 1, as shown in FIG. 1, passes through the inside of the printing device 1, and is discharged outside the system of the printing device 1 on the downstream side of the printing device 1 (the X1 side in the X direction).

[0016] 1, the printing device 1 includes a printer 11, a print receiving roller 12, an upstream guide roller 131, a downstream guide roller 132, a hand-reeling unit 14, and a downstream discharge roller 133. The printing device 1 controls the printing operation by the print head 111 by detecting the moving speed of the long film F with an encoder (not shown).

[0017] The printer 11 is disposed midway along the transport path of the long film F, facing upward relative to the transport path of the long film F. The printer 11 is mounted so as to be movable in the Y direction (the width direction of the long film F). Note that in this embodiment, the printer 11 is disposed above the transport path of the long film F, but this is not limited to this, and the printer 11 may be disposed, for example, below, to the left, or to the right of the transport path of the long film F.

[0018] The printer 11 includes a print head 111. The print head 111 is disposed opposite the print receiving roller 12, sandwiching an ink ribbon (not shown) transported by a ribbon transport mechanism (not shown) and the long film F therebetween. The print head 111 is configured to be movable in the vertical direction Z. The print head 111 prints on the long film F transported from the upstream side to the downstream side.

[0019] The print head 111 is disposed opposite the long film F being transported in the transport direction. The print head 111 is configured to be movable relative to the print receiving roller 12 to a standby position (see FIG. 1) where it is separated from the print receiving roller 12, or to a pressing position where it presses the print receiving roller 12.

[0020] The print receiving roller 12 is disposed opposite the print head 111 with the ink ribbon and the long film F sandwiched between them. With the long film F disposed between the print receiving roller 12 and the print head 111, the print receiving roller 12 is rotatable with at least a portion of the long film F wrapped around its circumferential surface. In this embodiment, the print receiving roller 12 has both the function of receiving pressure from the print head 111 and the function of guiding the long film F.

[0021] The upstream guide roller 131 is disposed upstream of the print receiving roller 12 and guides the movement of the long film F upstream of the print receiving roller 12. The downstream guide roller 132 is disposed downstream of the print receiving roller 12 and guides the movement of the long film F downstream of the print receiving roller 12.

[0022] Reeling unit 14 is disposed downstream of downstream guide roller 132. Reeling unit 14 has a roller unit 151, which guides the movement of long film F downstream of downstream guide roller 132 while printing device 1 is in printing operation. Reeling unit 14 can be manually operated by a person to reel in long film F in the longitudinal direction while printing device 1 is not in printing operation. Details of reeling unit 14 will be described later.

[0023] The downstream discharge rollers 133 are disposed downstream of the reel unit 14 and discharge the long film F downstream of the roller unit 151 of the reel unit 14 to the outside of the printing device 1 system.

[0024] In the printing device 1 configured as described above, the long film F is passed over the upstream guide roller 131, the print receiving roller 12, the downstream guide roller 132, the roller portion 151 of the reeling unit 14, and the downstream discharge roller 133 in that order. During the printing operation, the long film F introduced into the printing device 1 is transported through the upstream guide roller 131, the print receiving roller 12, the downstream guide roller 132, the reeling unit 14, and the downstream discharge roller 133 in that order, and is then discharged outside the system.

[0025] The reeling unit 14 will now be described in detail. The reeling unit 14 is located downstream of the downstream guide roller 132, and is therefore located downstream of the print head 111. The reeling unit 14 is fixed so that, during the printing operation of the printing device 1, the reeling operation of reeling the long film F in the longitudinal direction is not performed. On the other hand, while the printing operation of the printing device 1 is stopped, a person can manually operate the reeling unit 14 to reel the long film F in the longitudinal direction and perform the reeling operation of reeling the long film F in the longitudinal direction.

[0026] As shown in Figures 1 and 2, the gripping portion 14 includes a roller portion 151 that extends in the Y direction and is rotatable, a roller center shaft 152 that is arranged passing through the center of the roller portion 151, a knurled knob 153, a fixed knob 154 (fixed portion), a pair of pinion gears 155, a pair of racks 156, a groove portion 16 that extends in the X direction, a scale portion 17, and an indicator portion 157.

[0027] Roller unit 151 is disposed between front panel 101 and rear panel 102 of printing device 1. Reeling unit 14 is configured to allow roller unit 151 to move in the X direction. Long film F is wound around roller unit 151. Reeling unit 14 allows a person to manually move roller unit 151 while the printing operation of printing device 1 is stopped, thereby reeling long film F in the longitudinal direction and moving long film F in the longitudinal direction.

[0028] The roller central shaft 152 is formed to extend in the Y direction and penetrates the radial center of the roller portion 151. Both longitudinal ends of the roller central shaft 152 penetrate the groove portion 16 provided in the front panel 101 and the groove portion 16 provided in the rear panel 102. The groove portion 16 provided in the front panel 101 and the groove portion 16 provided in the rear panel 102 are formed to extend in the X direction, and by supporting both longitudinal ends of the roller central shaft 152 movably in the X direction, the roller portion 151 is supported movably in the X direction.

[0029] A pair of pinion gears 155 are fixed to the roller central shaft 152 on the inner surface of the front panel 101 and the inner surface of the rear panel 102. The end of the roller central shaft 152 on the Y1 side in the Y direction is disposed so as to penetrate to the outside of the rear panel 102 on the Y1 side in the Y direction, and a fixing member 152b is attached to the end of the roller central shaft 152 on the Y1 side in the Y direction.

[0030] The end of the roller central shaft 152 on the Y2 side in the Y direction is positioned to penetrate to the outside of the front panel 101 on the Y2 side in the Y direction, and a knurled knob 153 is attached to the outside of the front panel 101 on the Y2 side in the Y direction of the roller central shaft 152, and a fixed knob 154 is attached to the end of the roller central shaft 152 on the Y2 side in the Y direction, outside the Y2 side of the knurled knob 153 in the Y direction.

[0031] The knurled knob 153 is configured to be movable in the axial direction of the roller central shaft 152 along a key portion 152a that is provided on the roller central shaft 152 and extends in the axial direction, and by engaging with the key portion 152a that is provided on the roller central shaft 152, it rotates in synchronization with the rotation of the roller central shaft 152.

[0032] The fixing knob 154 can fix the roller portion 151 at a predetermined position in the X direction of the groove portion 16. The fixing knob 154 has a threaded portion 154a that meshes with a threaded portion 152c at the end of the roller central shaft 152 on the Y2 side in the Y direction. By rotating the fixing knob 154, a fixing member 152b attached to the end of the roller central shaft 152 on the Y1 side in the Y direction moves toward the rear panel 102.

[0033] To fix the roller unit 151, while holding the knurled knob 153 by hand, rotate the fixing knob 154 in the tightening direction to move the roller central shaft 152 toward the Y2 side in the Y direction, and by sandwiching the front panel 101 with the knurled knob 153 and sandwiching the rear panel 102 with the fixing member 152b, the front panel 101 is fixed by the frictional force of the contact surfaces between the front panel 101 and the knurled knob 153 and the frictional force of the contact surfaces between the rear panel 102 and the fixing member 152b. If the front panel 101 were sandwiched and fixed between the knurled knob 153 and the pinion gear 155, the backlash between the pinion gear 155 and the rack 156 would cause the roller unit 151 to move only on the Y1 side (rear side) in the Y direction, which could make it impossible to maintain the parallelism of the roller unit 151. When the fixing of the fixing knob 154 is to be released, the fixing knob 154 is rotated in the loosening direction to reduce the frictional force, and the fixing of the fixing knob 154 is released.

[0034] A configuration that allows the roller portion 151 to move in the X direction will be described. A pair of racks 156 extending along the X direction in which the groove portion 16 extends are fixed to the inner surface of the front panel 101 and the inner surface of the back panel 102. Each of the pair of racks 156 is formed to extend in the X direction, and each is meshed with a pair of pinion gears 155 fixed to the roller central shaft 152.

[0035] To move the roller portion 151 in the X direction, the knurled knob 153 is rotated while the roller portion 151 is released from the fixed state at the fixing knob 154. As a result, the knurled knob 153 engages with the key portion 152a provided on the roller central shaft 152, causing the roller central shaft 152 and the pinion gear 155 fixed to the roller central shaft 152 to rotate. Then, because the pinion gear 155 is engaged with the rack 156, the roller central shaft 152 moves in the X direction along the rack 156 extending in the X direction from the state shown on the left in FIG. 3 to the state shown on the right, thereby moving along the groove portion 16 extending in the X direction. After the roller portion 151 has been moved in the X direction, the fixing knob 154 is tightened to fix the roller portion 151 at a predetermined position in the X direction.

[0036] The position of roller portion 151 in the X direction can be adjusted visually using scale portion 17 and indicator portion 157 that moves together with roller portion 151. By visually checking the longitudinal position of roller portion 151 placed in groove portion 16 using scale portion 17, the position of roller portion 151 in the movement direction can be confirmed.

[0037] In the printing device 1 of this embodiment, in one printing operation, a printing range H of the long film F having a certain length in the conveying direction of the long film F (a portion of the length of the long film F in the conveying direction, see Figure 3) is supplied to the printing device 1, and after a predetermined interval, printing is performed on the printing range H of the long film F having a certain length in the conveying direction of the long film F (a portion of the length of the long film F in the conveying direction, see Figure 3) in the next printing operation, and these operations are repeatedly performed. In this embodiment, the long film F is transported by transport control of a packaging machine (not shown) or the like, and the printing device 1 cannot control the transport of the long film F. Therefore, the timing of the operation to supply the printing range H of the long film F (a portion of the length of the long film F in the conveying direction, see Figure 3) to the printing device 1 may not coincide with the timing of printing on the long film F by the printing device 1.

[0038] For example, in the case of printing device 1, if the product to be packaged in the packaging machine is changed and the printing range H (part of the length of the long film F in the conveying direction, see Figure 3) of one printing operation by printing device 1 is changed, when the printing operation by printing device 1 is performed while controlling the printing by printing device 1 by the transport of the long film F before the change, the timing of the operation to supply the long film F to printing device 1 and the timing of printing on the long film F by printing device 1 do not match, and printing device 1 may stop in the middle of the printing operation, as shown in the left diagram of Figure 3.

[0039] Therefore, in order to prevent the printer 1 from stopping midway through the printing operation, when the product to be packaged in the packaging machine is changed, for example, during initialization when the product to be packaged in the packaging machine is changed and the printing operation of the printer 1 is stopped, a person manually moves the roller unit 151 from the position shown in the left diagram of Fig. 3 to the position shown in the right diagram of Fig. 3 to perform a manual operation of reeling in the long film F, so as to match the timing of the new product. In this way, even when the product to be packaged in the packaging machine is changed, even when film transport of the long film F by the packaging machine is stopped, the printing operation by the printer 1 can be performed without stopping at the position of the print range H (part of the length of the long film F in the transport direction) in the length of the long film F in the transport direction of one printing operation by the printer 1.

[0040] In this way, by performing a manual operation to move the long film F in the longitudinal direction by manually reeling in the long film F while the printing operation of the printing device 1 is stopped, it is possible to synchronize the operation timing of supplying the long film F to the printing device 1 with the timing of printing on the long film F by the printing device 1. This prevents the long film F from stopping in the middle of the printing operation, and prevents printing defects from occurring.

[0041] The movement range of roller portion 151 of reeling unit 14 in the X direction for the amount of reeling of long film F by roller portion 151 is set to be equal to or greater than the maximum value of print range H (part of the length of long film F in the transport direction, see FIG. 3) in one printing operation by printer 1, for example, when repeatedly printing (part of the length of long film F in the transport direction, see FIG. 3). For example, by setting the length of groove portion 16 in the X direction, the movement distance of roller portion 151 of reeling unit 14 in the X direction can be set.

[0042] 3, for example, the print range H (part of the length of the long film F in the transport direction) of one printing operation by the printer 1 is the range in which four lines of text are printed in the transport direction of the long film F, and in the printing operation of the printer 1, printing operations are repeated at predetermined intervals in the print range H (part of the length of the long film F in the transport direction) of one printing operation by the printer 1. Therefore, it is necessary to reel in the long film F with the roller unit 151 of the reel unit 14 for a length equal to or greater than the print range H (part of the length of the long film F in the transport direction) of one printing operation by the printer 1.

[0043] On the other hand, for example, in a case where the product to be packaged in the packaging machine is changed and the print range H (the length of the long film F in the feed direction) of one printing operation by the printer 1 is changed, a person can manually pull in the reeling unit 14 while the printing operation of the printer 1 is stopped, thereby moving the roller unit 151 of the reeling unit 14 in the X direction. Therefore, in consideration of a case where the product to be packaged in the packaging machine is changed and the print range H (a portion of the length of the long film F in the feed direction) of one printing operation by the printer 1 is changed, the movement range of the roller unit 151 of the reeling unit 14 in the X direction for the amount of reeling in the long film F by the roller unit 151 is set to at least half the maximum value of the print range H (a portion of the length of the long film F in the feed direction) of one printing operation by the printer 1, for example, when the print range H (a portion of the length of the long film F in the feed direction) of one printing operation by the printer 1 is repeatedly printed. This is because the amount of movement of roller portion 151 of hand-holding portion 14 is half the amount of movement of long film F.

[0044] According to the printing device 1 of the first embodiment, for example, the following effects are achieved. The printing device 1 of this embodiment is a printing device that prints on a long film F that is transported from the upstream side to the downstream side, and is equipped with a print head 111 and a reeling unit 14 that is arranged downstream of the print head 111, and is fixed so that no reeling operation is performed to reel the long film F in the longitudinal direction to move the long film F in the longitudinal direction during the printing operation of the printing device 1, and is capable of performing a reeling operation to reel the long film F in the longitudinal direction to move the long film F in the longitudinal direction while the printing operation of the printing device 1 is stopped.

[0045] Therefore, while the printing operation of printing device 1 is stopped, roller portion 151 of reeling unit 14 can be manually moved in the X direction by a person and fixed at a predetermined position in the X direction. As a result, when the printing operation of printing device 1 is stopped, the printing operation of printing device 1 does not stop at the position of print range H (part of the length of long film F in the transport direction, see FIG. 3 ) of one printing operation by printing device 1, so that by manually reeling in long film F with reeling unit 14 while the printing operation of printing device 1 is stopped, it is possible to move long film F to a position that avoids the position where the printing operation will stop midway.

[0046] Therefore, while the printing operation of the printing device 1 is stopped, by performing a manual operation to move the long film F in the longitudinal direction by manually pulling the long film F in the longitudinal direction, it is possible to synchronize the operation timing of supplying the long film F to the printing device 1 with the timing of printing on the long film F by the printing device 1. This prevents the long film F from stopping in the middle of the printing operation, and reduces the occurrence of printing defects.

[0047] Furthermore, in this embodiment, the reeling unit 14 has a roller unit 151 around which the long film F is wound, and by moving the roller unit 151 while the printing operation of the printing device 1 is stopped, it is possible to perform a reeling operation to reel the long film F in the longitudinal direction and move the long film F in the longitudinal direction. As a result, by moving the roller unit 151, it is possible to easily perform a reeling operation to move the long film F in the longitudinal direction.

[0048] Furthermore, in this embodiment, hand-holding unit 14 has groove 16 formed to extend in the X direction and supporting roller 151 so that it can move in the X direction, and fixing knob 154 that can fix roller 151 at a predetermined position in the longitudinal direction of groove 16. As a result, by manually loosening fixing knob 154, roller 151 can be moved along groove 16, and roller 151 can be manually fixed at a predetermined position in groove 16 by fixing knob 154, the position of roller 151 of hand-holding unit 14 in the X direction can be easily changed manually.

[0049] Furthermore, in this embodiment, hand-holding unit 14 includes scale portion 17 that allows visual confirmation of the position in the movement direction of roller portion 151 disposed in groove portion 16. As a result, when changing the position of roller portion 151 of hand-holding unit 14 in the X direction, the position in the X direction can be easily grasped using scale portion 17, and therefore the position of roller portion 151 of hand-holding unit 14 in the X direction can be easily changed with high accuracy.

[0050] Next, a second embodiment of the present invention will be described. Fig. 4 is a diagram showing a case where a printing device 1A according to the second embodiment is provided in a label application device 2. The printing device 1A of the second embodiment is incorporated into, for example, the label application device 2. As shown in Fig. 4, the label application device 2 has a printer 11A of the printing device 1A that performs a printing operation on a labeled liner L supplied from a label web holder (not shown) that holds a wound labeled liner L, a guide roller 21, a hand-reeling unit 14A of the printing device 1A, and a label feeding unit 22.

[0051] The label application device 2 transports a long labeled backing sheet L (long body) to which a label La is temporarily attached, and performs a printing operation on the label La (printed portion) using the printing device 1A while the labeled backing sheet L is being transported, and then pays out the label La using the label payout unit 22 and attaches the label La to the object to which it is to be attached (not shown).

[0052] The printing device 1A includes a printer 11A and a feeding unit 14A, as shown in Fig. 4. The printing device 1A performs a printing operation on a label La temporarily attached to a label-attached liner L.

[0053] The reeling unit 14A is located downstream of the guide roller 21. As a result, the reeling unit 14A is located downstream of the print head 111A, similar to the reeling unit 14 in the first embodiment. The reeling unit 14A is fixed so that, during the printing operation of the printer 1A, the label-attached liner L is not reeled in the longitudinal direction to move the label-attached liner L in the longitudinal direction. On the other hand, while the printing operation of the printer 1A is stopped, a person can manually operate the reeling unit 14A to reel the label-attached liner L in the longitudinal direction to move the label-attached liner L in the longitudinal direction.

[0054] The configuration of the reel unit 14A of the second embodiment is mainly similar to the configuration of the reel unit 14 of the first embodiment, except that the object to be reeled is a long film F in the first embodiment but a labeled mount L in the second embodiment, and the orientation is different left to right. Therefore, for the reel unit 14A of the second embodiment, like components are given like reference numerals, and the description of the reel unit 14 of the first embodiment will be used, so a description thereof will be omitted.

[0055] According to the second embodiment, the handle portion 14A can be applied to a printing device 1A incorporated in a label application device 2, and the printing device 1A of the second embodiment can achieve the same effects as the printing device 1 of the first embodiment.

[0056] Although the preferred embodiments have been described above, the present invention is not limited to the above-described embodiments and can be embodied in various forms.

[0057] In the above embodiment, the printer 11, 11A is configured as one unit, but this is not limiting, and two or more printers 11, 11A may be arranged side by side along the conveyance direction of the elongated body.

[0058] In the above embodiment, one reel unit 14, 14A is provided, but this is not limited thereto, and two or more sets of reel units 14, 14A may be arranged side by side. In this case, the reel units 14, 14A form a two-stage reel, making it possible to reel in an even longer range of the long film F than in the above embodiment. When two or more sets of reel units 14, 14A are arranged, the two or more sets of roller units 151 can be moved by an individual movement mechanism that moves them individually, or by an interlocking movement mechanism that moves them in interlocking.

[0059] In the above embodiment, the hand-pulling units 14, 14A are manually operated by a person, but this is not limiting. The hand-pulling units 14, 14A may be automatically operated while the printing operation of the printer 1 is stopped. [Explanation of symbols]
