(Definition of terms)
In the present specification, the transfer direction of the knob-attached tape 9b is defined as “first direction”, and the transfer direction of the packaging film F is defined as “second direction”. Therefore, for example, the downstream side in the transport direction of the tape 9b with the knob is sometimes referred to as “first direction downstream side”, and the downstream side in the transport direction of the packaging film F is sometimes referred to as “second direction downstream side”.

(First embodiment)
With reference to FIG. 1 and FIG. 2, the outline | summary of the packaging film processing apparatus in 1st Embodiment is demonstrated. Drawing 1 is a mimetic diagram showing an outline of a packaging film processing device in a 1st embodiment. FIG. 2 is a diagram schematically showing an arrangement relationship between the inkjet head 4 and the tape 9b with a knob.

  The packaging film processing apparatus according to the first embodiment includes a tape forming unit 3 with a knob, an inkjet head 4, a tape cutting unit 5, a film transfer member 6, and a label applying unit 7.

  As illustrated in FIG. 1, the tape 9 a used in the embodiment is a tape having an adhesive layer 91 and a non-adhesive layer 92. In the example illustrated in FIG. 1, the adhesive layer 91 constitutes a first surface layer (back surface layer), and the non-adhesive layer 92 constitutes a second surface layer. In the example illustrated in FIG. 1, the entire first surface (back surface) of the tape 9a is an adhesive surface, and the entire second surface opposite to the first surface is a non-adhesive surface.

  The tape forming portion 3 with the knob has a sticking portion 94 on the first side portion 93 by folding the tape 9a along the first straight line L1 along the longitudinal direction of the tape 9a. A tape 9b with a knob having a knob 96 is formed. The affixing portion 94 is a portion that is affixed to the packaging film F. On the other hand, the knob 96 is a portion that is gripped by the consumer at the time of opening, and is a portion that is not adhered to the packaging film F. The formed tape 9b with a knob is a long tape whose length in the direction along the boundary line L2 between the sticking part 94 and the knob 96 is longer than the tape width perpendicular to the boundary line L2. .

  The inkjet head 4 discharges ink to the tape 9b with a knob. As a result, a graphic such as an arrow and / or a character such as OPEN is printed on the tape 9b with a knob. In this specification, a region where a graphic such as an arrow and / or a character such as OPEN is printed is referred to as a print region R.

  As shown in FIG. 2, the longitudinal direction of the inkjet head 4 is preferably perpendicular to the boundary line L2. In other words, the longitudinal direction of the inkjet head 4 is preferably perpendicular to the transport direction of the tape 9b with the knob. In the example shown in FIG. 2, the length of the inkjet head 4 is larger than the tape width W1 of the tape 9b with a knob. Alternatively, the length of the inkjet head 4 may be smaller than the tape width W1 of the tape 9b with a knob.

  In the example illustrated in FIG. 1, the inkjet head 4 ejects ink onto the back surface of the tape 9 b with the knob. In addition, in this specification, "the back surface of the tape with a knob | pick part" means the surface which will face the packaging film F. FIG.

  The inkjet head 4 may eject ink only to one of the sticking part 94 and the picking part 96 of the tape 9b with the picking part, or both the sticking part 94 and the picking part 96 of the tape 9b with the picking part. Ink may be discharged. In addition, when ink is discharged to the adhesive layer 91 of the tape 9b with a knob (or a label 9c with a knob described later), the ink is sandwiched between the label 9c with the knob and the packaging film F. Ink is protected.

  The tape cutting unit 5 cuts the tape 9b with a knob to create a label 9c with a knob. In the example illustrated in FIG. 1, the tape cutting unit 5 cuts the tape 9b with the knob in a direction crossing the boundary line L2 (more specifically, a direction perpendicular to the boundary line L2).

  In the example illustrated in FIG. 1, the label 9c with a knob obtained by cutting has a rectangular shape. The length in the direction along the boundary line L2 of the label 9c with the knob portion (that is, the label width D1) is longer than the length in the direction perpendicular to the boundary line L2 of the label 9c with the knob portion (that is, the length D2 in the longitudinal direction). Also short.

  In the embodiment, the position of the printing region R and the position of the side edge E of the label 9c with the knob portion formed by the tape cutting unit 5 are in a desired positional relationship, in other words, the positional deviation of the printing region R. Is preferably suppressed. A method for suppressing the displacement of the print region R will be described later.

  The film transfer member 6 transfers the packaging film F in which the opening cut C is formed. The film transfer member 6 includes, for example, a transfer roller 61.

  The label sticking part 7 sticks the label 9c with a knob (more specifically, the sticking part 94 of the label 9c with a knob) to the region of the packaging film F where the opening cut C is formed. In the example illustrated in FIG. 1, the second direction (the transport direction of the packaging film F) and the longitudinal direction of the label 9c with a knob attached to the packaging film F coincide with each other.

  As mentioned above, in the packaging film processing apparatus in 1st Embodiment, it can print on the tape 9b with a knob | pick part formed by folding back the tape 9a which has a non-adhesion layer and an adhesion layer.

  In the example shown in FIG. 1, after the printing is performed on the tape 9 b with the knob, the tape 9 b with the knob is cut. Alternatively, after the tape 9b with the knob portion is cut, the label 9c with the knob portion created by cutting may be printed. In this case, the tape cutting unit 5 is changed from being provided on the downstream side in the first direction (downstream side in the transport direction of the tape 9b with the knob) with respect to the ink jet head 4, The first direction upstream may be provided.

(Detailed description of the first embodiment)
An example of the first embodiment will be described in more detail with reference to FIGS.

FIG. 4 is a schematic plan view showing an example of the packaging film processing apparatus 1A in the first embodiment. FIG. 5 is a schematic front view showing another example of the packaging film processing apparatus 1A in the first embodiment. FIG. 6 is a schematic side view showing an example of the label sticking unit 7. In FIG. 4, in order to avoid complication of the drawing, the description of some members such as the inkjet head 4 is omitted.

  In the example shown in FIG. 3, the packaging film processing apparatus 1 </ b> A includes a tape 9 a in addition to the tape forming unit 3 with a knob, the inkjet head 4, the tape cutting unit 5, the film transfer member 6, and the label pasting unit 7. A tape feeding unit 2 for feeding, a suction drum 8 and a control device 11 are provided.

The tape feeding unit 2 supports the tape winding body 9 and feeds out the tape 9 a from the tape winding body 9. The tape supply part 2 is supported by the main body part 10 of the packaging film processing apparatus 1A. The tape winding body 9 supported by the tape feeding unit 2 is a type of tape winding body in which no release paper is interposed between the tape layers. Alternatively, the tape winding body 9 may be a tape winding body of a type in which release paper is interposed between tape layers. In this case, the release paper is removed from the tape 9a in a region between the tape feeding unit 2 and the tape forming unit 3 with the knob.

(Tape forming part 3 with knob)
The tape forming part 3 with a knob part forms the tape 9b with a knob part by folding the tape 9a. In addition, the tape 9a bent by the tape forming unit 3 with the knob is a tape that does not include a release paper.

  In the example shown in FIG. 4, the tape forming unit 3 with the knob portion includes a raised portion 31 that raises the first side region 90 a of the tape 9 a with respect to the other region 90 b of the tape 9 a, and the raised first portion 31. A bent portion 32 that bends the tape 9a so that the side region 90a overlaps the other region 90b, and a pair of clamping rollers 35 that transport the tape 9b with a knob formed by bending the tape 9a. In the example shown in FIG. 4, one roller 35a of the pair of sandwiching rollers is a driving roller, and the tape 9b with the knob is transferred in the first direction by the driving force of the driving roller. In addition, each of the upright part 31, the bending part 32, and a pair of clamping roller 35 is supported by the main-body part 10 of 1 A of packaging film processing apparatuses.

(Suction drum 8)
In the example illustrated in FIG. 4, the packaging film processing apparatus 1 </ b> A includes the suction drum 8 on the first direction side with respect to the tape forming unit 3 with a knob. The suction drum 8 is supported by the main body 10 of the packaging film processing apparatus 1A via a drum support member 82 so as to be rotatable about the rotation axis AX.

  A plurality of suction holes 81 are provided on the outer peripheral surface of the suction drum 8, and the suction holes 81 communicate with a vacuum device (such as a vacuum pump) (not shown). The knob-attached tape 9b transferred in the first direction is guided so as to come into contact with the outer peripheral surface of the suction drum 8. In addition, it is the non-adhesive surface of the tape 9b with a knob | pick part that contacts the outer peripheral surface of the adsorption drum 8. FIG. In the example shown in FIG. 4, the non-adhesive surface of the knob-attached tape 9 b is positioned and held on the outer peripheral surface of the suction drum 8 by the suction force by the plurality of suction holes 81.

  In the first embodiment, both the printing process and the cutting process are performed on the tape 9b with the knob portion while the tape 9b with the knob portion is positioned and held on the outer peripheral surface of the suction drum 8. For this reason, the position of the printing region R and the position of the side edge E of the label 9c with the knob are in a desired positional relationship, and the displacement of the printing region R is suppressed.

  In the example illustrated in FIG. 3, the drum support member 82 (such as a bracket) that supports the suction drum 8 can be adjusted in position (for example, slidable) with respect to the main body 10 of the packaging film processing apparatus 1A. More specifically, the main body 10 includes a long hole 15 that guides the sliding movement of the drum support member 82, and the drum support member 82 with respect to the main body 10 is moved by moving the drum support member 82 along the long hole 15. The position of 82 can be adjusted. By adjusting the position of the drum support member 82, the sticking position of the label 9c with the knob on the packaging film F is adjusted. More specifically, the suction drum 8 is moved in parallel to the width direction of the packaging film F by moving the drum support member 82 in parallel to the longitudinal direction of the film transfer member 6 (transfer roller 61). As a result, the sticking position of the label 9c with the knob on the packaging film F is adjusted.

(Inkjet head 4)
In the example illustrated in FIG. 3, the inkjet head 4 is disposed so as to face the outer peripheral surface of the suction drum 8. More specifically, the inkjet head 4 is disposed so as to face the upper outer peripheral surface of the suction drum 8.

  The ink jet head 4 discharges ink to the tape 9b with a knob portion that is positioned and held on the outer peripheral surface of the suction drum 8. In other words, the inkjet head 4 discharges ink to the back surface (for example, the adhesive layer 91) of the tape 9b with the knob when the tape 9b with the knob is adsorbed by the suction drum 8. For this reason, when the ink is being discharged, the position of the tape 9b with the knob is not shifted.

  The inkjet head 4 is preferably a fixed inkjet head that does not move during printing. Since the inkjet head 4 is a fixed inkjet head, the manufacturing cost of the packaging film processing apparatus 1A is reduced. Further, since the inkjet head 4 does not move during printing, the inkjet head 4 is unlikely to fail. Furthermore, since the inkjet head 4 does not move during printing, the finished state of printing in the printing region R is good. In addition, as the inkjet head 4, for example, a general-purpose head used in a known inkjet printer is used.

  The inkjet head 4 is supported by the main body 10 of the packaging film processing apparatus 1A via a head support member 42 (such as a bracket). The head support member 42 may be attached to a drum support member 82 that supports the suction drum 8. When the head support member 42 is attached to the drum support member 82 and the position of the drum support member 82 is adjustable with respect to the main body 10, the position of the inkjet head 4 and the suction drum 8 is adjusted integrally (for example, , Slide movement). For this reason, when the position of the suction drum 8 is adjusted to change the sticking position of the label 9c with the knob on the packaging film F, it is not necessary to readjust the positional relationship between the suction drum 8 and the inkjet head 4. .

  As shown in FIG. 5, when the packaging film processing apparatus 1 </ b> A includes a pressing roller 18 that presses the tape 9 b with the knob portion against the suction drum 8, the inkjet head 4 is in the first direction relative to the pressing roller 18. It is preferable to arrange on the side (the downstream side in the transport direction of the tape 9b with the knob). In the example illustrated in FIG. 5, the inkjet head 4 is disposed between the pressing roller 18 and the tape cutting unit 5.

In the example illustrated in FIG. 3, the tape cutting unit 5 is disposed so as to face the outer peripheral surface of the suction drum 8. The tape cutting unit 5 includes a cutting blade 51. When the cutting blade 51 moves in a direction approaching the outer peripheral surface of the suction drum 8, the tape 9b with the knob is cut, and as a result of the cutting, the label 9c with the knob is formed. The suction drum 8 preferably includes a groove 86 that receives the tip of the cutting blade 51. In the example shown in FIG. 3, a plurality of grooves 86 are provided on the outer peripheral surface of the suction drum 8 at regular intervals. In addition, when the front-end | tip of the cutting blade 51 has approached the groove | channel 86, it is preferable that the rotational drive of the suction drum 8 is stopped.

  In the example illustrated in FIG. 3, the tape cutting unit 5 includes a cutting blade driving unit 58, and the cutting blade driving unit 58 drives the cutting blade 51. The cutting blade drive unit 58 is an actuator that can reciprocate the cutting blade 51, for example.

  In the example illustrated in FIG. 3, the tape cutting unit 5 (for example, the cutting blade 51) is disposed between the inkjet head 4 and the label applying unit 7. In other words, the inkjet head 4, the tape cutting part 5, and the label attaching part 7 are arranged in this order along the outer peripheral surface of the suction drum 8. In the example shown in FIG. 3, the moving direction of the cutting blade 51 is a direction along the radial direction (radial direction) of the suction drum 8, and parallel to the longitudinal direction of the film transfer member 6 (transfer roller 61). Direction.

(Labeling part 7)
In the example illustrated in FIG. 3, the label sticking portion 7 is disposed so as to face the outer peripheral surface of the suction drum 8. In the example illustrated in FIG. 3, the label 9 c with the knob and the packaging film F are supplied to the space between the label attaching unit 7 and the suction drum 8. Then, the label attaching portion 7 presses the label 9c with the pick portion and the packaging film F against the suction drum 8 so that the label 9c with the pick portion is attached to the packaging film F.

  More specifically, as shown in FIG. 6, the label sticking unit 7 includes a pressing member such as a pressing roller 78 and an actuator 79 that drives the pressing member. In addition, it is preferable that the rotating shaft of the press roller 78 is parallel to the longitudinal direction of the film transfer member 6 (for example, transfer roller 61 with the shortest distance from the label sticking part 7). The actuator 79 moves the pressing member toward the suction drum 8 when the opening cut C of the packaging film F opposes the label with the knob held by the suction drum 8. As a result, the label with the knob is attached to the packaging film F. In the example shown in FIG. 6, the transport direction of the packaging film F at the label attaching position is parallel to the rotation axis AX of the suction drum 8.

(Film transfer member 6)
The film transfer member 6 is a member that transfers the packaging film F in which the opening cut C is formed. The film transfer member 6 includes, for example, a transfer roller 61.

(Control device 11)
With reference to FIG. 3 and FIG. 4, the packaging film processing apparatus 1 </ b> A includes a control device 11. The control device 11 transmits an ink discharge signal to the inkjet head 4 in synchronization with the rotation of the suction drum 8 and controls the ink discharge timing. More specifically, the control device 11 controls the inkjet head 4 so that the ink is ejected at a timing when the inkjet head 4 is opposed to a region between two adjacent grooves 86 of the suction drum 8.

  Assume that the suction drum 8 is intermittently driven by the drum driving unit 88. In this case, it is preferable that the control device 11 controls the inkjet head 4 such that ink is ejected from the inkjet head 4 when the drum driving unit 88 rotates the suction drum 8. The control device 11 may execute both rotation control of the suction drum 8 and ink discharge control from the inkjet head 4. In addition, the control device 11 may perform drive control of the cutting blade 51. Alternatively or additionally, the control device 11 may control the ejection of ink from the inkjet head 4 in response to a signal from a detector that detects the rotation angle of the suction drum 8.

Therefore, the repeated description about these structures is abbreviate | omitted.

(Inkjet head 4)
The inkjet head 4 discharges ink toward the non-adhesive surface of the label 9c with a knob attached to the packaging film F.

  The inkjet head 4 is preferably a fixed inkjet head that does not move during printing. Since the inkjet head 4 is a fixed inkjet head, the manufacturing cost of the packaging film processing apparatus 1B is reduced. Further, since the inkjet head 4 does not move during printing, the inkjet head is unlikely to fail. Furthermore, since the inkjet head 4 does not move during printing, the finished state of printing in the printing region R is good.

  The inkjet head 4 is supported by the main body 10 of the packaging film processing apparatus 1B via a head support member 42a (such as a bracket). In FIG. 9, the connection mechanism between the main body 10 and the head support member 42a is not shown in order to avoid complication of the drawing.

  The inkjet head 4 is preferably adjustable in position in a direction parallel to the longitudinal direction of the film transfer member 6 (for example, a transfer roller). In this case, the inkjet head 4 may be provided so that the position thereof can be adjusted with respect to the head support member 42 a, or the head support member 42 a may be provided so as to be adjustable in position with respect to the main body 10. The position of the inkjet head 4 is adjusted according to the position of the label 9c with the knob in the direction parallel to the width direction of the packaging film F.

(Control device 11a)
The packaging film processing apparatus 1B includes a control device 11a. The control device 11a transmits an ink ejection signal to the inkjet head 4 in response to the detection unit 12 detecting the label 9c with the knob or the colored portion of the packaging film F, and controls the ink ejection timing.

  Assume that the detector 12 detects the label 9c with a knob. In this case, the control device 11a calculates the label arrival time by dividing the film transport distance between the detector 12 and the inkjet head 4 by the film transport speed. And the control apparatus 11a controls the inkjet head 4 so that the inkjet head 4 discharges an ink at the timing which passed label arrival time from the detection time of the label 9c with a knob | pick part by the detector 12. FIG.

  Alternatively, it is assumed that the detector 12 detects a colored portion of the packaging film F. The positional relationship between the colored part of the packaging film F and the label 9c with the knob part is constant. In this case, the above-described label arrival time is obtained by using the time obtained by dividing the distance between the colored portion and the label 9c with the knob portion (the distance along the transfer direction of the packaging film F) by the film transfer speed. May be corrected. And the control apparatus 11a controls the inkjet head 4 so that the inkjet head 4 discharges an ink at the timing which the label arrival time corrected from the detection time of the coloring part by the detector 12 passed.

  Further alternatively, the control device 11 a may transmit an ink discharge signal to the inkjet head 4 in synchronization with the rotation of the suction drum 8. For example, the control device 11a calculates the label arrival time by dividing the film transfer distance between the suction drum 8 and the inkjet head 4 by the film transfer speed. Then, the control device 11a detects the ink jet head at a timing when the label arrival time has elapsed from the time when the label 9c with the knob portion is detached from the suction drum 8 (the time when the label 9c with the knob portion is pasted). The inkjet head 4 is controlled so that 4 ejects ink. In this example, the detector 12 may be omitted.

  When the packaging film processing apparatus 1B includes the above-described control device 11a (or the above-described control device 11a and the detector 12), the position of the printing region R and the positions of the front and rear edges of the label 9c with the knob are desired. The positional relationship is established, and the displacement of the printing region R is suppressed.
