Description

  The present invention relates to a cutter for cutting a sheet such as a tape having a pressure-sensitive adhesive applied to the back surface, and a tape processing apparatus provided with the cutter.

  Conventionally, as this type of tape processing device, tape is processed by feeding a processing tape (sheet) with release paper coated with an adhesive while feeding it, cutting the printed part with a cutter, and creating a label The device is known. (For example, Patent Document 1)

In this case, the cutter is disposed in the vicinity of the tape discharge port formed in the apparatus case, and the cut label is discharged to the outside from the tape discharge port by its own weight. The cutter is a scissors type in which a fixed blade and a movable blade rotate relative to each other about a support shaft to perform cutting operation. The fixed blade is on the upstream side in the tape feed direction (the tape discharge port side). A movable blade is disposed on the surface. As a result, when the movable blade is cut and the processing tape is cut, the cut tape piece is ejected from the apparatus so as to be repelled by the movable blade.
By the way, although it depends on the pressure-sensitive adhesive used, when the treatment tape with pressure-sensitive adhesive is cut, the pressure-sensitive adhesive protrudes from the cut end and may adhere to the blade edges of both blades. As the movable blade blade repeats the cutting operation, the adhesive rubs against the blade backs of both blades and adheres in layers. For this reason, the tape piece after cutting may stick to the blade back of the fixed blade blade, and the processing tape on the cut side may stick to the blade back of the movable blade blade. Even if the adhesive does not adhere to the blade backs of both blades, the tape piece may stick to the blade backs of the fixed blade blades due to the adhesive protruding from the cut ends of the tape pieces. This causes double cuts and jamming.

Therefore, in the conventional cutter described above, a storage part containing silicone oil for preventing the adhesion of adhesive is attached to the back of the fixed blade, and each time the cutting operation is performed, silicone is applied to the back of both blades. The oil spreads and the sticking of the tape piece is prevented.

  However, such a conventional cutter has a problem that the structure is complicated by providing the silicone oil reservoir, and the cost of the cutter is high because silicone oil is used. In addition, the silicone oil is consumed over time, and there is a problem that adhesion of the adhesive cannot be prevented.

  Accordingly, it is an object of the present invention to provide a cutter capable of effectively preventing adhesion of a sheet to the back of a fixed blade blade and a movable blade blade with a simple structure, and a tape processing apparatus including the cutter. Yes.

  The cutter of the present invention has a fixed blade and a movable blade, and a sheet coated with an adhesive facing between the fixed blade of the fixed blade and the movable blade of the movable blade is used. Is a cutter that performs cutting operation between a non-cutting position that is spaced apart from each other and a cutting position that overlaps each other, and the movable blade that has been cut to the cutting position is movable on the back of the fixed blade blade. The blade edge of the blade blade faces and a relief groove extending along the blade edge is formed.

  According to this configuration, when the fixed blade and the movable blade are cut, the cut end of the sheet piece separated from the sheet advances along the back of the fixed blade blade so as to be pushed by the blade edge of the movable blade blade, Reach the escape groove position. That is, the cut end of the sheet piece moves to the position of the relief groove of the fixed blade blade at the cutting position. In this state, the cut end of the sheet piece faces the open part of the escape groove of the fixed blade blade.

That is, at the cutting position, the cutting end of the cut sheet moves to the position of the escape groove of the movable blade blade. In this state, the cut end of the sheet to be cut also faces the opening of the escape groove of the movable blade blade. For this reason, even if the adhesive protrudes from the cut end of the sheet, the cut end of the sheet is not in direct contact with the escape groove of the movable blade blade. There is no sticking to. Even when the adhesive is already attached to the back of the movable blade, the sheet floats against the relief groove and does not stick to the back of the fixed blade. Thereby, it is possible to effectively prevent the sheet on the cut side from being cut twice or jammed.

  In this case, it is preferable that the relief groove has a concave cross section by press molding.

  According to this configuration, when the relief groove is formed by press molding, the blade backs of both blades are slightly bent in a valley shape around the relief groove. That is, with the formation of the relief groove, a portion similar to so-called “backing” can be formed on the back of both blades.

  In this case, it is preferable that the fixed blade and the movable blade are of a scissor type in which the cutting operation is performed by relatively rotating around the support shaft.

  According to this structure, the advantage of the scissors that exhibits stable cutting performance over a long period of time as a cutter can be utilized.

The blade receiving member 82 is provided with a pair of upper and lower stoppers (not shown) that slightly protrude toward the cutting blade 69, and regulates the cutting depth of the cutting blade 69 cut in a scissor form. Only the recording tape Sr can be cut.

  As shown in FIG. 6, the discharge mechanism 45 uses the full cutter motor 51 of the full cut mechanism 53, which will be described later, as a power source, rolls the tape piece Ta after cutting, and forcibly discharges it. A vertical rotating shaft 72 branched from a full-cut power transmission mechanism 71 (described later) connected to the full cutter motor 51, a rotating drum 73 fixed to the upper portion of the vertical rotating shaft 72, and a movable provided on the lower peripheral surface of the rotating drum 73. 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 71 (see FIG. 5) 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 rotates (swings) about the support shaft 65 through the full cut power transmission mechanism 71. Thus, cutting into the processing tape T is performed and a full cut is made. The support shaft 65 of the full cutter 53 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 like 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 tape feed 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 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 full cutter 89.

  Therefore, it is possible to reliably prevent the tape piece Ta from being cut twice or jammed. 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 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.
