Description

  The present invention relates to a cutter mechanism for cutting a processing tape in its width direction in order to obtain a tape piece from a processing tape provided with an adhesive layer, and a tape processing apparatus including the cutter mechanism.

Conventionally, a cutter mechanism for cutting a processing tape in its width direction to obtain a tape piece from a processing tape (long tape) provided with an adhesive layer, which is sent downstream of the processing tape in the feeding direction. A movable blade disposed on the side and a fixed blade disposed on the upstream side in the feed direction, and both the movable blade and the fixed blade partially overlap with the non-cutting positions spaced apart from each other. A cutter mechanism including a cutter that performs a cutting operation between a cutting position and the cutting position is known (for example, see Patent Document 1).
JP-A-10-175190

  In such a cutter mechanism, when the processing tape is cut, the upstream end of the tape piece may adhere to the blade back of the fixed blade due to the adhesive protruding from the cut end surface of the processing tape. In particular, when the adhesive of the processing tape is easy to peel off from the tape substrate, when the movable blade cuts out, it sticks out of the adhesive from the processing tape and adheres to the back of the movable blade. As the process is repeated, the adhesive also accumulates on the back of the fixed blade that rubs against the back of the movable blade, so that the upstream end of the tape piece tends to adhere to the back of the fixed blade. If the tape piece adheres to the fixed blade, when the next processing tape is sent to the cutter, the processing tape is clogged at the cutter portion (jamming), which is a problem.

  However, in order to prevent the tape piece from adhering to the fixed blade, it is conceivable to apply an adhesion prevention liquid such as silicone oil to the movable blade and the fixed blade as described in the above patent document. Yes. However, even in this case, when oil runs out over time, depending on the type of adhesive, the adhesive accumulates on the back of the movable blade and the fixed blade, and the tape piece adheres to the fixed blade. It could not be completely prevented.

  It is an object of the present invention to provide a cutter mechanism and a tape processing apparatus provided with the cutter mechanism that can cut a processing tape even if a tape piece once adheres to the back of a fixed blade. Objective.

  The cutter mechanism of the present invention is a cutter mechanism that cuts a processing tape in the width direction in order to obtain a tape piece from a processing tape provided with an adhesive layer, and is downstream of the processing tape in the feeding direction. The movable blade and the fixed blade disposed on the upstream side in the feed direction, and the blades of the movable blade and the fixed blade are spaced apart from each other, and the cut partially overlaps. A cutter that performs a cutting operation between the position and the back of the fixed blade, and presses the upstream end of the tape piece toward the movable blade as the movable blade returns to the non-cutting position. And a pressing means.

  According to this configuration, even if the upstream end of the tape piece is once attached to the back of the fixed blade due to the adhesive deposited on the back of the fixed blade, the upstream end of the tape piece is on the movable blade side. By being pressed, the tape is forcibly separated from the back of the fixed blade, so that the tape piece does not remain attached to the back of the fixed blade. When the adhesion is released, the tape piece separates from the fixed blade due to its own weight or the like. Therefore, the processing tape that is sent is not clogged with the cutter portion.

  In this case, it is preferable that the cutter is of a scissor type including a movable blade and a fixed blade that share a support shaft.

  According to this configuration, since the cutter is a scissors type, the press contact state of the movable blade and the fixed blade is stable, and the cutting performance can be maintained for a long time.

  In these cases, the pressing means faces the cutting edge of the movable blade, and is configured to advance and retract along the back of the fixed blade, and a biasing member that biases the pressing member toward the movable blade. It is preferable to have.

  According to this configuration, the pressing member is pushed by the movable blade with the processing tape sandwiched in accordance with the cutting operation of the movable blade to the cutting position, and therefore is retracted to the blade back side of the fixed blade against the biasing member. As the movable blade returns to the non-cut position, the upstream end of the tape piece is moved to the movable blade side by being urged to the movable blade side by the urging member and following the movable blade. Press on. For this reason, the tape piece can be pressed to the movable blade side with a simple configuration without hindering the cutting operation of the cutter.

The pressing member is preferably disposed at a position where the pressing surface in contact with the processing tape is substantially flush with the edge of the fixed blade in the cutting direction of the movable blade when the movable blade is in the non-cutting position. . According to this, the tape piece adhering to the fixed blade can be reliably separated from the fixed blade without the pressing member preventing the feeding of the processing tape.
In addition, it is preferable to use a leaf spring as the urging means. According to this, since the size in the urging direction is smaller than that of the coil spring, the space in the urging direction on the back surface of the pressing member is small. This can also be arranged.

  In this case, it is preferable to further include a guide member that guides the advancement / retraction of the pressing member, and the guide member is configured by a guide pin that is formed in the pressing member and engages with a long hole extending in the advance / retreat direction.

  According to this configuration, the pressing member moves forward and backward while being guided by the guide pin while being allowed to swing around the guide pin. For this reason, the pressing member can smoothly advance and retreat by swinging according to the cutting angle of the movable blade, and the tape piece can be pressed uniformly in the width direction.

  In this case, it is preferable to further include a stopper member that the pressing member engages at the forward end position of the pressing member where the front end of the pressing member reaches the cutting edge of the fixed blade.

  According to this configuration, the front end of the pressing member is located at the same position as the edge of the fixed blade or slightly at the front. Thereby, the front-end | tip of the processing tape sent does not catch on a press member.

  In this case, it is preferable that the pressing surface of the pressing member in contact with the processing tape is formed in an uneven shape along the width direction of the processing tape.

  According to this configuration, even if the downstream end of the processing tape or the upstream end of the tape piece and the pressing surface come into contact with the cutting operation of the movable blade, the contact area is reduced, so that the downstream side of the processing tape There is no possibility that the end or the upstream end of the tape piece adheres to the pressing surface. Note that it is also effective to subject the pressing surface to fluorine treatment instead of or together with forming the pressing surface to be uneven.

  In these cases, the treatment tape is composed of a tape main body provided with an adhesive layer on the back surface and a release tape attached to the tape main body via the adhesive layer, and the cutter of the cutter mechanism is the A full cutter that cuts both the tape body and the release tape, and is disposed on the downstream side of the full cutter, and further includes a half cutter that cuts either the tape body or the release tape of the processing tape. The cutter has a cutting blade provided on the movable blade side of the full cutter and a blade receiving member provided on the fixed blade side of the full cutter with respect to the processing tape being sent, and the pressing means is fixed in the feeding direction. It is preferable to be interposed in the gap between the blade and the blade receiving member.

If a gap exists between the fixed cutter of the full cutter and the blade receiving member of the half cutter in the feed direction of the treatment tape, the downstream end of the treatment tape that is fed passes through the gap and the blade It may face the upstream side surface of the receiving member and may contact the upstream side surface in the feed direction of the blade receiving member. In this case, the adhesive accumulates on the upstream side surface of the blade receiving member, and the downstream end of the processing tape may adhere.
In this respect, according to this configuration, since the pressing means is interposed between the fixed cutter of the full cutter and the blade receiving member of the half cutter, the downstream end of the processing tape sent to the blade receiving member Even if it goes to the upstream side surface, since the progress is hindered by the pressing means, it does not come into contact with the upstream side surface of the blade receiving member. Accordingly, the adhesive does not accumulate on the upstream side surface of the blade receiving member, and the downstream end of the processing tape does not adhere.
Note that this configuration is particularly effective when the processing tape is unwound from the wound state and the downstream end of the processing tape tends to face the upstream side surface of the blade receiving member due to the winding rod.

  In these cases, it is preferable to further include a tape discharging means that rolls on the tape piece and forcibly discharges the tape piece to the outside on the downstream side of the cutter feeding direction.

  According to this configuration, the tape piece separated from the fixed blade by the pressing means can be reliably discharged to the outside by the tape discharging means.

  The tape processing apparatus of the present invention comprises a tape cartridge that accommodates a processing tape so that the processing tape can be unwound, the above-described cutter mechanism, a cartridge mounting portion on which the tape cartridge is detachably mounted, and a tape feeding means for feeding the processing tape. And an apparatus main body.

  According to this configuration, a cutting mechanism is provided for cutting the processing tape without leaving the tape piece attached to the back of the fixed blade. Can be performed continuously, and a plurality of tape pieces can be produced at a time.

  In this case, it is preferable that the apparatus main body further includes a printing unit that prints ink characters on the processing tape that is sent and / or a stamping unit that performs braille printing on the tape piece.

  According to this configuration, ink characters can be printed and / or braille stamped on a tape piece, so that a variety of labels can be created.

And a plurality of rolling contact pieces 74. When the rotary drum 73 rotates in response to the power of the full cutter motor 51, that is, in synchronization with the cutting operation of the full cutter 89, the plurality of rolling contact pieces 74 spread outward due to centrifugal force and come into contact with the tape piece Ta, At the same time as the tape piece Ta is cut, it is discharged to the outside from the tape discharge port 11.

  As shown in FIGS. 5 and 6, the full cut mechanism 53 includes a full cutter 89 having a fixed blade 59 and a movable blade 60, a full cutter motor 51 that supplies power for performing full cut, and the movable blade 60. A full-cut power transmission mechanism 71 for transmitting the power of the full cutter motor 51; and a tape pressing means 97 for pressing the tape piece Ta back to the movable blade 60 after separating the tape piece Ta from the processing tape T. Yes.

  The full cut power transmission mechanism (see FIG. 5) 71 includes a reduction gear train composed of a plurality of gears and a crank mechanism (crank disc 75), and the power of the full cut motor 51 is transmitted via the full cut power transmission mechanism 71. The cutting operation of the movable blade 60 and the above-described discharging operation for discharging the cut tape piece Ta are converted.

  The full cutter 89 is of a scissor type in which a fixed blade 59 and a movable blade 60 are rotatably connected by a support shaft 65, and the fixed blade 59 is located upstream of the tape feeding direction 98 (inside the apparatus). The movable blade 60 is disposed on the downstream side (outside of the apparatus) in the tape feeding direction 98 (see FIG. 7). The fixed blade 59 and the movable blade 60 are formed in a substantially “L” shape so as to be compact. The fixed blade 59 is fixed to the base support portion 63 with the spacer 81 interposed therebetween, and the movable blade 60 is rotatably supported by the fixed blade 59 via the support shaft 65. That is, the full cutter 89 is cut (cut) into the processing tape T by rotating (swinging) the movable blade 60 about the support shaft 65 through the full-cut power transmission mechanism 71. Has been made.

  The support shaft 65 of the full cutter 89 is positioned substantially at the center in the longitudinal direction of the base portion 56, and the cutting edge 90 of the fixed blade 59 and the cutting edge 91 of the movable blade 60 face each other across the tape feed path 23. Arranged. The cutting edge 91 of the movable blade 60 is formed in a slightly warped shape so that the cutting angle is constant.

  The fixed blade 59 is formed in a substantially L shape by the fixed blade base 61 and the fixed blade blade 62, and the fixed blade base 61 is fixed to the base support portion 63 together with the spacer 81, and the fixed blade blade 62 is supported by the fixed blade blade support portion 64 in a state of being fastened together with the spacer 81 and the blade receiving member 82 of the half cutter 96. In addition, a static elimination brush 83 that neutralizes static electricity of the processing tape T is attached to the blade surface 62a across the fixed blade blade 62 in the extending direction of the blade edge 90.

  The movable blade 60 is formed in a substantially L shape similarly to the fixed blade 59, and a movable blade base 78 extending in the longitudinal direction of the base portion 56 from the side of the full cutter 89 toward the sheet feeding path 23. The movable blade blade 79 extending substantially vertically from the movable blade base 78 is supported. A slot 87 is formed in the movable blade base 78 in the extending direction. The power of the full cut motor 51 is transmitted through the long hole 87 (via the crank disc 75), and the cutting operation of the movable blade 60 is performed. In this cutting operation, the position of the movable blade blade 79 is regulated by the long hole 87, the cutting position (cutting position) where the fixed blade blade 62 and the movable blade blade 79 overlap, the fixed blade blade 62 and the movable blade blade 79. And reciprocatingly rotate between a non-cutting position (non-cutting position) that separates in a V shape (see FIG. 7).

  As shown in FIGS. 5 to 7, the blade edge 91 of the movable blade blade 79 that has been cut at the cutting position faces the blade back 62 b of the fixed blade blade 62, and a relief groove 84 that extends along the blade edge 91. Is formed. The escape groove 84 has a width of about 2 mm to 3 mm and a depth of about 0.3 mm to 0.5 mm, and has a concave cross section (U shape). Further, the escape groove 84 has substantially the same length as the cutting edge 91 of the movable blade blade 79 and is slightly curved following the shape (warping) of the cutting edge 91. In other words, the cutting edge 91 of the movable blade blade 79 that has been cut to the cutting position comes to a substantially intermediate position in the width direction of the opening 94 of the escape groove 84.

  With this configuration, when the fixed blade 59 and the movable blade 60 are cut, the cut end 86 of the separated tape piece Ta is pushed by the cutting edge 91 of the movable blade 60 along the blade back 62b of the fixed blade 62. To reach the position of the escape groove 84. That is, the cut end 86 of the tape piece Ta moves to the position of the relief groove 84 of the fixed blade blade 62. In this state, the cut end 86 of the tape piece Ta faces the open portion 94 of the escape groove 84 of the fixed blade blade 62. Therefore, when the adhesive protrudes from the cut end 86 of the tape piece Ta, the cut end 86 of the tape piece Ta does not come into contact with the escape groove 84 of the blade back 62b. It does not adhere to 62b. Further, even when the adhesive has already adhered to the blade back 62b, the tape piece Ta is positioned apart and does not adhere to the escape groove 84 of the blade back 62b. Thereby, the effect of preventing twice cutting and jamming can be obtained.

  Similarly, the blade edge 90 of the fixed blade blade 62 that has been cut at the cutting position faces the blade back 79b of the movable blade blade 79, and a relief groove 85 that extends along the blade edge 90 is formed. Also in this case, the escape groove 85 has a width of about 2 mm to 3 mm and a depth of about 0.3 mm to 0.5 mm, and has a concave cross section (U shape). Further, the escape groove 85 has substantially the same length as the cutting edge 90 of the fixed blade blade 62 and is a straight line following the shape (straight line) of the cutting edge 90. That is, the blade edge 90 of the fixed blade blade 62 that has been cut to the cutting position comes to a substantially intermediate position in the width direction of the opening 95 of the relief groove 85.

  With this configuration, when the fixed blade 59 and the movable blade 60 perform the cutting operation, the cut end 93 of the processing tape T on the cut side is restricted by the cutting edge 90 of the fixed blade 59, and the clearance groove of the movable blade 60 is relatively moved. The position 85 is reached. That is, the cut end 93 of the processing tape T on the cut side moves to the position of the relief groove 85 of the movable blade blade 79. In this state, the cut end 93 of the processing tape T on the cut side also faces the opening 95 of the relief groove 85 of the movable blade blade 79. Therefore, when the adhesive protrudes from the cut end 93 of the processing tape T, the cut end 93 of the processing tape T does not come into contact with the escape groove 85 of the blade back 79b. It does not adhere to 79b. Further, even when the adhesive has already adhered to the blade back 79b, the processing tape T is separated in position and does not adhere to the escape groove 85 of the blade back 79b.

  Both the blades 62 and 79 are preferably formed by press molding, and at that time, the relief grooves 84 and 85 are also preferably formed by press molding at the same time. In this way, both the blades 62 and 79 are slightly bent around the escape grooves 84 and 85, and a portion similar to so-called “backing” is formed. This improves the cutting performance of the full cutter 89 and makes it difficult for the adhesive to adhere to the blade backs 62b and 79b. In particular, when the scissors are mounted on the apparatus as in the embodiment, it is impossible for the user to disassemble the apparatus and remove the adhered adhesive, and the scissors in the embodiment are extremely suitable for mounting on the apparatus. It becomes effective.

  Further, the full cutter 89 of the present invention can be applied not only to this embodiment but also to, for example, a general Western scissors and a gripping scissors.

  On the other hand, the tape pressing means 97 is disposed along the blade back 62b side of the fixed blade blade 62, a pressing member 80 that advances and retreats in the same direction as the cutting direction, and a leaf spring that urges the pressing member 80 from the rear. Urging member) 92 and a fixed blade side spacer piece 76 of the spacer 81 that supports the pressing member 80 and the leaf spring 92. The spacer 81 is formed in a substantially U shape by a fixed blade side spacer piece 76 and a movable blade side spacer piece 77 arranged with the tape feed path 23 interposed therebetween. The fixed blade side spacer piece 76 has a concave portion 99 with a rectangular window on the surface on the half cutter 96 side, and a pressing member 80 and a leaf spring 92 are incorporated in the concave portion 99.

  As shown in FIGS. 7 and 8, the pressing member 80 is opposed to the cutting edge 91 of the movable blade 60 (movable blade blade 79), and the blade receiving member 82 of the half cutter 96 and the blade back 62 b of the fixed blade blade 62. Between the pressing member main body 46 directly facing the cutting edge 91 of the movable blade 60, a main body supporting piece 47 extending rearward from the pressing member main body 46, and an intermediate upper portion of the main body supporting piece 47. A guide long hole 48 cut horizontally from the rear and two stopper portions 49 that are located above and below the guide long hole 48 and project from the main body support piece 47 are integrally formed.

  The pressing member main body 46 has substantially the same length as the cutting edge 91 of the movable blade 60 and is formed in a cross-sectional arrowhead shape. As a result, the tip of the processing tape T that is sent is smoothly guided to the front surface of the blade receiving member 82. Further, the pressing surface 44 of the pressing member main body 46 is formed in an uneven shape in the longitudinal direction. Thereby, even if the frictional resistance with the processing tape T sent is reduced and the cut end 86 of the tape piece Ta contacts the pressing surface 44, it does not stick.

  The guide long hole 48 is engaged with a guide pin 39 projecting from the recess 99 of the fixed blade side spacer piece 76, and the pressing member 80 is guided by the guide pin 39 in a state in which swinging is allowed. To advance and retreat. In a state where the pressing member 80 is moved to the forward end position, the two stopper portions 49 abut against the front edge of the recessed portion 99 with the rectangular window of the fixed blade side spacer piece 76, and the forward end position of the pressing member 80 is position-regulated. Is done. Further, in this state, the tip of the pressing member main body 46 (the pressing surface 44 thereof) is at the same position as the cutting edge 90 of the fixed blade 59 or a slightly front position. As a result, the tip of the processing tape T that is sent is not held by the pressing member 80.

  On the other hand, the leaf spring 92 has substantially the same width as the thickness of the pressing member 80, and is formed in a V shape by the fixing portion 118 and the urging portion 119. The fixed portion 118 of the leaf spring 92 is attached in the vicinity of the rear edge of the recessed portion 99 with a rectangular window so as to be inserted into a part of the recessed portion 99, and the tip of the urging portion 119 formed in an arc shape. The part 119 a abuts against the rear end surface (stopper portion 49) of the pressing member 80 and biases it toward the cutting edge 91 of the movable blade 60. The tip portion of the urging portion 119 is positioned behind the guide pin 39 in the horizontal direction (advancing and retreating direction), and urges the pressing member 80 that moves forward while allowing the guide pin 39 to swing, with a good balance. The piece Ta can be pressed uniformly in the width direction. Although a coil spring can be used instead of the leaf spring 92, the leaf spring 92 having a small size in the urging direction is advantageous in consideration of the space in the forward / backward direction.

  When the movable blade 60 (movable blade blade 79) starts the cutting operation from the non-cutting position toward the cutting position, the cutting edge 91 of the movable blade blade 79 cuts into the processing tape T from below. At this time, the pressing member 80 moves backward against the leaf spring 92 so as to be pressed against the cutting edge 91 of the movable blade blade 79 with the processing tape T interposed therebetween. When the processing tape T is cut and the movable blade blade 79 reaches the cutting position, the pressing member 80 further reaches the retracted end position against the leaf spring 92. In this state, the tape piece Ta cut from the processing tape T is lightly sandwiched between the pressing member 80 and the blade edge 91 of the movable blade blade 79 at the cut end 86. Normally, at this time, the discharging force of the discharging mechanism 45 is superior to the frictional force caused by the pinching, and the tape piece Ta is discharged.

  For example, a large amount of pressure-sensitive adhesive accumulates in the escape groove 84, or a large amount of pressure-sensitive adhesive protrudes from the cut end 86 of the tape piece Ta, and the cut end 86 of the tape piece Ta sticks to the blade back 62b of the fixed blade blade 62. Then, when the discharge force of the discharge mechanism 45 loses this sticking force, when the movable blade blade 79 starts a cutting operation toward the non-cutting position, the pressing member 80 is moved by the leaf spring 92 to the movable blade blade 79. And the cut end 86 of the tape piece Ta is pressed. As a result, the cut end 86 of the tape piece Ta is momentarily separated from the blade back 62b of the fixed blade blade 62, and the discharge force of the discharge mechanism 45 acts to discharge the tape piece Ta. Of course, even if the discharge mechanism 45 is not provided, the tape piece Ta is discharged so that the tape discharge port 11 falls due to its own weight as soon as it is separated from the blade back 62b of the fixed blade blade 62.

  Thus, the processing tape T facing the movable blade 60 and the fixed blade 59 of the full cutter 89 is cut by the cutting operation of the movable blade 60, and the cut end (upstream end) 86 of the cut tape piece Ta is fixed. Even when the adhesive accumulated on the blade back 62b of the blade 59 once adheres to the blade back 62b of the fixed blade 59, the cutting end 86 of the tape piece Ta is pressed toward the movable blade 60, whereby the fixed blade 59 of the fixed blade 59 is pressed. Since it is forcibly separated from the blade back 62b, the tape piece Ta does not remain attached to the blade back 62b of the fixed blade 59. Further, the tape piece Ta can be pressed toward the movable blade 60 without interfering with the cutting operation of the cutter. Therefore, it is possible to reliably prevent the tape piece Ta from being cut twice or jammed.

  Further, the tape pressing means 97 (pressing member 80) is interposed between the fixed blade 59 of the full cutter 89 and the blade receiving member 82 of the half cutter 96, so that the processing tape T is sent downstream. Even if the end is directed to the upstream side surface of the blade receiving member 82, the tape pressing means 97 prevents the progress thereof, so that it does not contact the upstream side surface of the blade receiving member 82. Therefore, the adhesive is not deposited on the upstream side surface of the blade receiving member 82, and the downstream end of the processing tape T is not attached. In particular, in the present embodiment, as described above, the processing tape T is fed out from the state of being wound in the tape cartridge C. Therefore, the downstream end of the processing tape T is located upstream of the blade receiving member 82 due to the winding rod. This configuration is particularly effective because it tends to face the side.

  The pressing member 80 according to the embodiment has a structure that presses (advances / retreats) the tape piece Ta by being urged by the leaf spring 92. However, the pressing member 80 advances / retreats in conjunction with the cutting operation of the movable blade 60 using a link mechanism or the like. It is good also as a structure to do. For example, a link having a long hole 87 orthogonal to the long hole 87 of the movable blade 60 is connected to the pressing member 80, and power for advancing and retreating is obtained from the crank disk 75.
