Description

  The present invention relates to a laminating apparatus characterized by a blade attachment structure in office equipment and other sheet cutter parts, and a blade attachment structure in sheet cutter parts.

  A laminating apparatus that laminates paper such as a card with a sheet such as a synthetic resin film is known.

  FIG. 23 is a perspective view showing a conventional laminating apparatus. FIG. 24 is a schematic configuration diagram showing main components of a conventional laminating apparatus.

  The prior art laminating apparatus 100 is roughly composed of a sheet feeding unit I, a sheet feeding unit II, a laminating unit III, and a cutting unit IV.

  Here, the paper supply unit I is a part that supplies paper P such as documents and cards, and is provided with a paper feed tray 101.

A guide plate 101a that guides the sheet P to the nipping positions of the nipping rollers 103a and 103b is provided at the leading end of the sheet feeding tray 101. The paper feed tray 101 is mounted on the apparatus main body 100a, and the guide path portion formed by the guide plate 101a is between the non-adhesive sheet roll 102a and the adhesive sheet roll 102b of the sheet cassette 102 mounted on the apparatus main body 100a. It enters a state of entering.
The subsequent sheet supply unit II is a part that supplies a sheet for laminating the paper P. The sheet supply unit II is of a cassette type, and two sheet rolls 102a and 102b are rotatably supported in the sheet cassette 102 as shown in FIG. Among the sheet rolls in the sheet cassette 102, the sheet roll 102a illustrated in the upper part of the drawing is a roll of a long strip-shaped non-adhesive sheet S1 formed of a synthetic resin film. The sheet roll 102b shown in the lower part of the drawing is obtained by winding a long strip-shaped adhesive sheet S2 having an adhesive layer formed on one side of the film in a roll shape so that the adhesive surface is on the inside. .
Then, from the sheet cassette 102 of the sheet supply unit II, both the adhesive surfaces of the adhesive sheet S2 fed out from the adhesive sheet roll 102b are opposed to the non-adhesive sheet S1 fed out from the non-adhesive sheet roll 102a. The sheets are stacked and supplied to the laminating section III.
The laminating part III is a part having a pair of sandwiching rollers 103a and 103b. In the laminating section III, the sheet P supplied from the sheet supply section I is sandwiched between the sandwiching rollers 103a and 103b and laminated. That is, the paper P is supplied between the gripping rollers 103a and 103b while being sandwiched between the pair of sheets S1 and S2, and the sheets S1 and S2 and the paper P are integrated.

  The cutting part IV is a part that cuts the laminate R sent out from the laminating part III, more specifically, the sheet P laminated with the sheets S1 and S2 in a direction perpendicular to the feeding direction. In the prior art laminating apparatus, the cutting part IV is provided with a horizontal cutter blade 104 for cutting the laminate R in a direction (hereinafter referred to as X direction) perpendicular to the feeding direction.

  As shown in FIGS. 23B and 24, the horizontal cutter blade 104 is slidable on a shaft 104a spanned in the width direction of the apparatus main body 100a on the delivery side of the laminated body R of the sandwiching rollers 103a and 103b. It is supported by. Then, the laminated body R is fed to an arbitrary cutting position, and the lateral cutter blade 104 is slid in the width direction at that position so that the laminated body R can be cut in the X direction at an arbitrary position in the feeding direction. It has become.

When using the laminating apparatus 100 configured as described above, first, the non-adhesive sheet S1 fed out from each of the non-adhesive sheet roll 102a and the adhesive sheet roll 102b supported above and below the sheet cassette 102, and The leading end portions of the adhesive sheet S2 are bonded to each other and sandwiched between the holding rollers 103a and 103b. Subsequently, the paper P such as a card is placed on the paper feed tray 101, and the paper P is pushed forward. As a result, the leading edge of the sheet P is guided by the guide plate 101a, and the sheet P passes between the sheets S1 and S2 fed out from the non-adhesive sheet roll 102a and the adhesive sheet roll 102b, respectively, and the nipping positions of the nipping rollers 103a and 103b. Led to.
Subsequently, when one of the gripping rollers 103a is rotated in a predetermined direction by operating the handle 103c, the paper P is drawn into the gripping rollers 103a and 103b together with the non-adhesive sheet S1 and the adhesive sheet S2, and the paper P is pulled by the sheets S1 and S2. Laminated, it becomes a laminated body R and is sent out forward.

  Then, when the laminate R is cut in the X direction by the horizontal cutter blade 104, paper (laminate) laminated with a sheet such as a PET film is obtained.

  The conventional laminating apparatus described above has a horizontal cutter blade and can cut the laminate R to an arbitrary length. Therefore, in the prior art laminating apparatus, an edge portion where the sheets to be laminated are bonded to each other can be left with an arbitrary width at the edge portion in the feeding direction of the paper P.

  However, the prior art laminating apparatus only has means for cutting the laminate R in the X direction, and does not have means for cutting the laminate R in the feed direction (hereinafter referred to as Y direction).

  That is, the width of the sheet roll mounted on the laminating apparatus is determined in stages according to the standards and the like, whereas the width of the paper P laminated by these sheets is not always constant. Therefore, the width of the edge portion in the X direction of the completed laminate R changes depending on the width of the paper P, and the width of the edge portion formed on the edge portion of the paper P in the X direction is arbitrarily set. Could not set.

Therefore, when the width of the paper P is extremely small compared to the width of the sheet to be laminated and the width of the edge portion in the X direction of the finished laminate R becomes larger than necessary, the laminate cut by the horizontal cutter blade 104 is used. There was a problem that an unnecessary border portion left in the X direction of the body R had to be cut separately with scissors or a cutter.

  Therefore, the applicant can first provide the cutting portion IV with a vertical cutter blade that cuts the laminate R in the feed direction, that is, the Y direction, and can cut the laminate R not only in the X direction but also in the Y direction. The laminating apparatus was invented and filed as Japanese Patent Application Nos. 10-67755 and 10-67755.

The invention previously filed by the present applicant has a configuration in which a vertical cutter blade is provided between a horizontal cutter blade of the prior art and a holding roller.
The vertical cutter blade adopted in Japanese Patent Application No. 10-67755 is a so-called triangular blade, and maintains a posture in which the blade edge faces the upstream side in the feeding direction of the laminate R, and is arranged downstream of the sandwiching roller. Is done.
And the laminated body R sent out from the pinching roller hits the vertical cutter blade, and the laminated body R is cut in the feeding direction.

  In the invention filed by the present applicant as Japanese Patent Application No. 10-67755, etc., a so-called triangular blade cutter is employed as described above, and the laminate R is cut using the feed force of the holding rollers 103a and 103b. .

  That is, in the above-described configuration, cutting is performed by using the movement of the laminated body R by receiving the force from the holding roller 103ab, and pressing the laminated body R by using only the moving force of the laminated body R. It is.

  Therefore, the vertical cutter blade must always come into direct contact with the laminate R, and when the vertical cutter blade is shaken, the sharpness is remarkably reduced. However, the previous invention has not taken measures against blurring of the vertical cutter blade.

  Moreover, since the previous invention pushes and cuts off the laminate R itself only by the moving force of the laminate R as described above, the vertical cutter blade must always be sharp, and when the sharpness of the blade decreases, The cut surface of the laminate R is disturbed.

  Therefore, it is necessary to replace the vertical cutter blade periodically. However, since the vertical cutter blade is extremely sharp, the replacement blade is dangerous and requires careful storage. Furthermore, since the vertical cutter blade is extremely sharp, the operator may be injured when the blade is replaced. That is, the laminating apparatus has a strong demand for downsizing the outer shape due to the property of being used on a desk, and the mounting position of the vertical cutter blade is narrow. Therefore, the replacement work must be done by hand and often touches the cutting edge by mistake.

  Therefore, the present invention further improves the laminating apparatus described in Japanese Patent Application No. 10-67755 previously disclosed by the applicant and develops a laminating apparatus that can smoothly cut the laminate R in the feeding direction. Let it be an issue. That is, the present invention develops a laminating apparatus in which the vertical cutter blade can be easily replaced, the risk of injury during the blade mounting operation is low, and the safety when storing the replacement blade is high.

Since the presser bar 35 is attached to the swing piece 36 attached to the shaft center 31 a of the driven roller 31 as described above, it moves along with the movement of the driven roller 31. Accordingly, when the swing arm 33 is swung upward and the driven roller 31 is released, the presser bar 35 is also moved together, and there is no hindrance when the sheet cassette 20 is mounted.
Conversely, when the swing arm 33 is moved downward and the driven roller 31 is set at a predetermined position, the presser bar 35 is positioned between the vertical cutter blade 43 and the holding roller 30 and is provided on the drive roller side. It abuts on the surface 81 (described later).

  The driven roller 31 is attached to the swing arm 33 through a long hole 38 as shown in FIG. 5A, and can move along the long hole 38 when it is separated from the drive roller 32. is there. When the driven roller 31 is separated from the driving roller 32, the driven roller 31 is urged by a spring or the like and moves along the elongated hole 38. Also, as shown in FIGS. 6 to 10, the receiving member 31 b that holds the shaft center 31 a of the driven roller 31 is provided with a guide having an opening at the top, so that when the swing arm 33 is lowered, The shaft center 31a moves along the guide and fits in a predetermined position.

  The reason why the driven roller 31 is free to be mounted and the driven roller 31 can be moved in this manner is to eliminate the interference with other members by moving the driven roller 31 when the swing arm 33 is opened and closed. This is because the swing trajectory of the swing arm 33 is increased to ensure better workability.

The function of the holding roller 30 is to hold the sheet P fed between the adhesive sheet S1 and the adhesive sheet S2 supplied from the sheet cassette 20 mounted in the sheet supply unit B together with the adhesive sheets S1 and S2, It sends out while joining the person. The sheet P sandwiched between the pressure-sensitive adhesive sheets S1 and S2 supplied from the sheet cassette 20 is sent out while being held by the holding roller 30, so that the laminate R in which the paper P is laminated by the pressure-sensitive adhesive sheets S1 and S2 is obtained. can get.

And the friction member 80, such as a cork, is provided in the back surface side of the overhang | projection part 61a. The friction member 80 is not limited to cork as long as it has a larger coefficient of friction than the material of the main body 55, and rubber, leather, cloth, or the like can also be employed.
A plate body 55a is attached to the front surface side of the main body 55 at a position near the lower surface thereof.

  Inside the main body portion 55, a block portion 60 is provided at an intermediate portion near the lower surface, and a vertical cutter blade 43 is attached to the block portion 60. The vertical cutter blade 43 is fixed to the block portion 60 as described above, and the tip of the tip is exposed downward from the main body portion 55.

  The moving member 56 of the mounting member 52 is made by resin injection molding or the like, and the shape and function are greatly different between the upper part a, the intermediate part b and the lower part c as shown in FIG. Specifically, the operation member 62 and the engaging claw 63 are formed on the upper part a side, the hinge part 65 is formed on the intermediate part b, and the sliding part and the cover member 72 are formed on the lower part c.

  That is, the upper part of the moving member 56 is a lever-like operation member 62. The operation member 62 has a plate-like bottom plate member 62a at the center, and the periphery thereof is covered with an upper surface member 62b and a side member 62c.

  The bottom plate member 62a exists only in the operation member 62, that is, the upper part a of the moving member 56, and there is no member corresponding to the bottom plate member in the intermediate part b and the lower part c of the moving member 56.

  Further, the bottom plate member 62a protrudes from the intermediate portion of the operation member 62 toward the front side. Two slits 62d are formed in the bottom plate member 62a in the vertical direction, and the slits 62d open at the lower end of the bottom plate member 62a. Therefore, the portion sandwiched between the slits 62d constitutes a cantilevered engaging claw 63. In the present embodiment, the distal end portion of the engaging claw 63 functions as a pressing portion 67 that presses the second horizontal wall 58d of the base member 51. Further, the cantilevered portion of the engaging claw 63 has a function of changing the operation member 62 to the forward tilt posture.

  A substantially triangular notch 62f is provided in the vicinity of the boundary between the operation member 62 and the hinge portion 65 and on the back side of the side member 62c. In the present embodiment, a part of the side member 62c that is located below the notch 62f functions as the engagement wall 62g in the width direction.

  The bottom plate member 62a is provided with a protrusion 62h. A thin cover member 74 is attached to the protrusion 62h. The cover member 74 is a thin plate that covers the front surface of the moving member 56, and is provided to prevent catching when another member touches the cutter holder 50. Since the cover member 74 is a member for the purpose of preventing such a catch, it is recommended to use a material having a low friction coefficient.

The hinge portion 65 of the moving member 56 is a portion that joins a portion where the operation member 62 or the like is provided and a portion where the sliding portion and the cover member 72 are provided, and is configured by a narrow plate. . That is, the hinge part 65 does not have a member corresponding to a side member, and does not have a member corresponding to a bottom plate member. Therefore, the section modulus of the hinge part 65 is smaller than other parts and is easily bent. In the lower part c of the moving member 56, a sliding side surface 68 is provided on the same plane as the side surface member 62c. The sliding side surface 68 is the widest portion of the lower portion c of the moving member 56, and is an end surface of the plate-like portion in this embodiment, and has a small thickness.
A reinforcing rib 69 is provided slightly inside the sliding side surface 68.

Further, two projecting pieces 70 are provided symmetrically at the lower portion c of the moving member 56. The projecting piece 70 is a member in which a substantially “L” -shaped member is supported in a cantilevered manner, and includes a support piece 70 a extending horizontally from the upper end portion of the reinforcing rib 69, and the support piece 70 a. It is comprised by the drooping piece 70b drooping from the front-end | tip. The support piece 70a and the hanging piece 70b of the protruding piece 70 are both thin plate-like. And the lower end of the drooping piece 70b is slightly curved inward. In the present embodiment, the curved portion functions as the cover member 72. The cover member 72 is the tip of the thin plate-like protruding piece 70 as described above, and the width thereof is equal to or larger than that of the vertical cutter blade 43.

  As described above, the mounting member 52 is composed of the main body portion 55 and the moving member 56, and both are engaged and integrated.

  That is, the sliding side surface 68 of the moving member 56 is attached to a box-shaped part surrounded by the back member 49, the top member 53, the bottom member 54, and the left and right side members 61 of the main body 55. The sliding side surface 68 of the lower portion c is engaged with the inside of the side surface member 61 of the main body portion 55. Further, the protruding piece 70 of the lower part c is inserted into the slit 54 a of the lower surface member 54 of the main body part 55. Further, the side member 62 c of the operation member 62 is engaged with the notch 53 a of the upper surface member 53.

  Therefore, the moving member 56 can move slidably with respect to the main body portion 55. When the moving member 56 is moved to the main body 55 side, the tip of the protruding piece 70 protrudes from the lower surface of the main body 55 as shown in FIGS. 10, 14, and 15, and the vertical cutter blade 43 provided on the main body 55. To the vicinity of the cutting edge. That is, when the moving member 56 is moved to the main body portion 55 side, the cover member 72 simultaneously protrudes from the main body portion 55 and surrounds and covers the vertical cutter blade 43. That is, the two rows of cover members 72 are positioned on both sides of the vertical cutter blade 43 and surround the vertical cutter blade 43.

At this time, the operation member 62 side of the moving member 56 takes a posture inclined toward the front of the main body portion 55. That is, when the moving member 56 is moved to the main body portion 55 side, the inclined portion of the engaging member 63 of the operation member 62 contacts the upper surface member 53 of the main body portion 55 as shown in FIG. Press toward. Here, the operating member 62 of the moving member 56 and the sliding side surface 68 are connected by a hinge portion 65 having a small section modulus, and the hinge portion 65 is easily bent. Therefore, the moving member 56 is bent from the hinge portion 65 by the force that the engaging member 63 receives from the upper surface member 53 of the main body portion 55, and has a substantially “<” shape as a whole.
The side shape of the mounting member 52 at this time is as shown in FIG. 14, the operation member 62 of the moving member 56 falls forward, the one side 62 e of the notch 62 f becomes vertical, and the periphery of the upper surface member 53 of the main body 55 There are no obstacles.
On the other hand, when the moving member 56 is moved in the pulling direction from the main body 55, the cover member 72 moves upward, and the cover member 72 is immersed in the main body 55.

The engaging member 63 of the moving member 56 moves further above the upper surface member 53 of the main body 55, and the engaging wall 62g below the notch 62f of the side member 62c has a peripheral portion of the upper surface member BR> T3. Located in. As a result, the operation member 62 of the moving member 56 assumes an upright posture. The side surface shape of the mounting member 52 at this time is as shown in FIGS. Appears.

  Next, a procedure for attaching the cutter holder 50 will be described.

  A pedestal member 51, which is a constituent member of the cutter holder 50, is attached to the support shaft 44 so as to be rotatable and slidable as shown in FIGS.

  Then, the mounting member 52 is attached to the pedestal member 51, and the vertical cutter blade 43 is attached at a predetermined position.

When attaching the mounting member 52, the moving member 56 is moved to the main body 55 side as shown in FIG. As a result, two cover members 72 appear around the vertical cutter blade 43 and surround and cover the vertical cutter blade 43. Therefore, even if the operator touches the mounting member 52 by hand, the blade edge of the vertical cutter blade 43 does not touch a finger or the like. Therefore, even when the operator is forced to work by hand as in the case where the vertical cutter blade 43 is attached to a narrow place, the blade edge is completely covered, and the safety of the operator is ensured.

  Further, when the moving member 56 is moved to the main body 55 side, the operation member 62 side of the moving member 56 is tilted forward in the shape of “<” as described above, and one side 62e of the notch 62f is in a vertical state. There is no obstacle around the upper surface member 53 of the main body 55 (see FIG. 14).

  As a result, as shown in FIG. 14, the end surface shape around the upper portion of the main body portion 55 of the mounting member 52 matches the uneven shape of the end surface of the slide track portion 58 of the base member 51. Therefore, the operator moves the mounting member 52 from the end surface of the pedestal member 51 along the slide track portion 58 to fit the mounting member 52 to the pedestal member 51.

  Subsequently, the moving member 56 is pulled upward in the drawing, and the moving member 56 is moved in a direction to be pulled out from the main body portion 55. As a result, the state shown in FIG. 15 is changed to the state shown in FIG. 16, and the cover member 72 at the tip of the protruding piece 70 is immersed in the main body 55 and the vertical cutter blade 43 is exposed.

  Subsequently, the mounting member 52 is slightly tilted backward. As a result, the pressing portion 67 of the engaging claw 63 of the mounting member 52 engages with the engaging wall 58e of the base member 51. At the same time, the lower engaging wall 62g of the notch 62f engages with the outer surface of the width direction engaging portion 58f.

  Therefore, the vertical portion 53 c of the upper surface member 53 of the main body portion 55 is fitted into the groove formed by the first vertical wall 58 a and the second vertical wall 58 c of the pedestal member 51, and the upper surface of the horizontal portion of the upper surface member 53 is the pedestal member 51. The engaging claw 63 of the mounting member 52 engages the pedestal member 51 with the engaging wall 58e, and the upper surface of the horizontal portion of the upper surface member 53 faces the second surface of the pedestal member 51. The pressing is performed on the lower surface of the horizontal wall 58d, and the engaging wall 62g of the side member 62c of the mounting member 52 is engaged with the width direction engaging portion 58f.

Therefore, the mounting member 52 is positioned and fixed firmly to the base member 51 in any of the front, rear, left, and right directions.
When the moving member 56 is in the withdrawn state, that is, when the cover member 72 is immersed in the main body portion 55 and the vertical cutter blade 43 of the mounting member 52 is in a bare state, the mounting member 52 is attached to the pedestal member 51. I can't.
That is, when the moving member 56 is in the pulled-out state, the engaging member 63 of the moving member 56 moves further above the upper surface member 53 of the main body 55, and the operation member 62 of the moving member 56 takes an upright posture. As a result, an obstacle (engagement wall 62g) appears around the upper surface member 53 of the main body 55 of the mounting member 52, and the end surface shape of the mounting member 52 does not match that of the base member 51. For this reason, the mounting member 52 cannot be attached to the pedestal member 51, so that the operator can be prevented from working in the hand-capped state, and the operator's safety is ensured.

  Next, components of the penetration / separation mechanism 46 will be described.

The penetration / separation mechanism 46 includes a support shaft 44 extending in the X direction supported by the chassis 1a, a swing lever 76 integrated with a reaction force generating member 75, a coil spring 46c, and a disc cam 46d.
The reaction force generating member 75 is made by bending a steel plate, and is a long member having a “U” cross-sectional shape as shown in FIGS. 9, 10, 14, and 17. That is, the reaction force generating member 75 has a top surface 75a, a front surface 75b, and a back surface 75c.
Further, one end of the swing lever 76 is integrated with a part of the reaction force generating member 75 described above, and the side surface has an arcuate shape. A hole 76a through which the shaft is inserted is provided in the curved portion. Further, a folding portion is provided on the other end side of the swing lever 76, and a contact portion 76b of the disc cam 46d is formed. The disc cam 46d is in contact with the contact portion 76b (
6-8). The rotating shaft 46e of the disc cam 46d is connected to a motor (not shown).

  Further, one end of the coil spring 46c is attached in the vicinity of the abutting portion 76b, and always urges the swing lever 76 in the clockwise direction.

  The support shaft 44 is inserted into the hole 57 a of the pedestal member 51 described above, and the pedestal member 51 is further fixed to the top surface 75 a of the reaction force generating member 75.

  A friction member 80 such as a cork provided on the main body 55 of the mounting member 52 of the cutter holder 50 contacts the front surface 75 b of the reaction force generating member 75.

  In the penetration / separation mechanism 46, the disc cam 46d is rotated by a motor (not shown) to swing the cutter holder 50, so that the vertical cutter blade 43 penetrates the laminated body R and a position away from the laminated body R. Can be changed.

  That is, as shown in FIGS. 6 and 7, when the portion of the disc cam 46d close to the rotating shaft 46e is in contact with the contact portion 76b of the swing lever 76, the reaction force generating member 75 and the cutter holder 50 are rotated clockwise. The vertical cutter blade 43 is in a state separated from the laminate R as shown in FIGS.

  Conversely, as shown in FIG. 8, when a portion of the disc cam 46d far from the rotation shaft 46e contacts the contact portion 76b of the swing lever 76, the reaction force generating member 75 and the cutter holder 50 rotate counterclockwise. The vertical cutter blade 43 penetrates the laminate R as shown in FIG.

  Moreover, in this embodiment, it has the receiving member 47 formed of elastic members, such as urethane foam which receives the vertical cutter blade 43. FIG.

  Moreover, the laminating apparatus of this embodiment is provided with the receiving surface 81 along the lower surface of the laminated body R sent out from the laminating process part C like FIGS. The receiving surface 81 is a floor shape made of a steel plate or the like, extends from immediately after the driving roller 32 of the holding roller 30 to the downstream side, and reaches a position immediately before the cutter holder 50. The receiving surface 81 is slightly inclined immediately after the driving roller 32, and thereafter is a flat surface.

  Therefore, when the vertical cutter blade 43 is caused to penetrate the laminated body R by the penetration / separation mechanism 46 and the laminated body R is sent out from the laminate processing unit C, the cutting edge is directed to the upstream side in the feeding direction of the laminated body R. The laminated body R is cut in the Y direction by the cutter blade 43.

  At this time, when the vertical cutter blade 43 does not sufficiently penetrate the laminate R, various troubles such as cutting failure and feed failure occur in the laminate R. As described above, the vertical cutter blade When 43 penetrates the laminated body R, as shown in FIGS. 8 and 20, the leading end portion of the vertical cutter blade 43 pierces the receiving member 47, so that the laminated body R can be surely damaged without damaging the vertical cutter blade 43. Can be penetrated. Therefore, it is possible to prevent troubles such as defective cutting of the laminated body R and extend the service life of the vertical cutter blade 43.

  As described above, in this embodiment, the vertical cutter blade 43 of the vertical cutting mechanism 42 of the cutting part D is disposed between the laminating part C and the horizontal cutting mechanism 41 so as to cut the laminate R. Therefore, various members necessary for cutting the laminate R can be shared between the horizontal cutting mechanism 41 (the horizontal cutter blade 41a) and the vertical cutting mechanism 42 (the vertical cutter blade 43), and the cutting unit The occupied space of D can be kept small.

  In addition, as described above, the vertical cutting mechanism 42 allows the vertical cutter blade 43 to penetrate the laminated body R by the penetrating / separating mechanism 46, and then the laminating unit C sends out the laminated body R, whereby the laminated body R is converted into Y. Since the cutting is performed in the direction, the cutting mechanism itself is simple and compact, and the space occupied by the cutting portion D can be further reduced. In particular, as described above, when the cutter blade 43 is passed through the laminate R between the laminating unit C and the transverse cutting mechanism 41, the laminating unit C and the transverse cutting mechanism 41 (lateral cutter blade 41a) Therefore, it is possible to reduce the width of the unnecessary edge portion that always remains between the laminating portion C and the horizontal cutter blade 41a.

  Further, the laminating apparatus 1 of the present embodiment includes a separate switching mechanism 48. The switching mechanism 48 is a mechanism for switching between a case where the sheet P is cut while leaving only an edge to which the sheet is adhered and a case where the sheet P is cut at a position substantially equal to the width of the sheet P and no edge is left. Next, the switching mechanism 48 will be described.

  As shown in FIG. 18, the switching mechanism 48 includes a slide shaft 48b extending in the X direction, an operation lever 48d that rotates the slide shaft 48b, and a cam mechanism 48e that approaches and separates by rotation of the slide shaft 48b by the operation lever 48d. ing. In other words, the cam mechanism 48e includes a fitting portion 48g and a guide holder 48c, and is connected to the guide holder 48c and the cam block 48f via a coil spring 48h that urges them in the direction in which they approach each other. Is always in close contact. The opposing surfaces of the guide holder 48c and the cam block 48f are formed with concave and convex cam surfaces that fit each other, and both come close to and away from each other by rotating relative to each other about the slide shaft 48b. ing.

Further, as shown in FIG. 5A, in the state where the guide holder 48c and the cam block 48f are close to each other, the laminate R is cut along the edge in the X direction of the paper P positioned by the paper guide 12. The vertical cutter blade 43 is guided so that the cutting edge comes to the first cutting position α.
On the other hand, in a state where the guide holder 48c and the cam block 48f are separated from each other, the vertical cutter blade 43 is guided to a position shifted outward from the guide surface of the paper guide 12 by the relative movement amount L of both. That is, in this case, the cutting edge of the vertical cutter blade 43 comes to the second cutting position where the outer edge is cut by the relative movement amount L from the edge in the X direction of the paper P positioned by the paper guide 12.

  The operation of the laminating apparatus 1 configured as described above will be described in the order of use. First, as a first preparation stage, the sheet cassette 20 is mounted in the sheet supply unit B. Specifically, the swing arm 33 attached to the main body is swung upward as shown in FIGS. 5 and 6, and the driven roller 31 and the pressing bar 35 are released to secure the storage space for the sheet cassette 20. Further, a motor (not shown) is rotated to operate the penetrating / separating mechanism 46 to swing the cutter holder 50 so that the vertical cutter blade 43 is raised.

  Subsequently, the sheet cassette 20 is mounted at a predetermined position. When the sheet cassette 20 is mounted, the tips of the adhesive sheets S1 and S2 of the sheet cassette 20 are bonded to each other in advance. In this state, the adhesive sheets S1 and S2 are pulled out obliquely downward from the housing 23. When the sheet cassette 20 is placed, the protruding tips of the adhesive sheets S1 and S2 are placed on the driving roller and the receiving surface 81 as shown in FIG.

At this time, the front ends of the pressure-sensitive adhesive sheets S1 and S2 stroke the front surface of the cutter holder 50. Since the cover member 74 is provided on the front surface of the cutter holder 50, the pressure-sensitive adhesive sheets S1 and S2 are covered with the cover body. The surface of the member 74 is not slid and caught on the cutter holder 50.
Then, after the sheet cassette 20 is disposed at a predetermined position, the swing arm 33 is lowered. When the swing arm 33 is lowered and lowered, the shaft center 31a of the driven roller 31 fits into the guides of the receiving members 31b provided on both sides of the main body, moves along the guides, and draws a predetermined locus to drive roller 32. It fits in the position where it touches.
The presser bar 35 moves together with the driven roller 31 and is disposed in the immediate vicinity of the driven roller 31. Further, the pressing bar 35 is pressed against the receiving surface 81 by the spring 37.

  Subsequently, the switching mechanism 48 is operated to select whether the stacked body R has an edge portion or no edge portion.

  When the preparation is completed in this way, the paper P to be laminated is placed on the paper feed tray 11. When the drive roller 32 is rotated, the pair of adhesive sheets S1 and S2 are wound on the holding roller 30 in a state where they overlap each other, and the paper P on the paper feed tray 11 advances together with the adhesive sheets S1 and S2.

  Further, before and after the advance of the paper P, a sensor (not shown) detects the size of the paper P on the paper feed tray 11 and drives a belt (not shown) to move one cutter holder 50 so that the size of the paper P is reached. The cutter holder 50 is moved to a position corresponding to. Here, when the switching mechanism 48 described above selects the laminated body R having no border, the cutter holder 50 stops at a position corresponding to the end of the paper P. On the other hand, when the switching mechanism 48 selects the laminated body R having a border, the cutter holder 50 stops at a position slightly outside from the end of the paper P.

  That is, when the paper P positioned in the X direction by the paper guides 12a and 12b is fed into the sheet supply unit B, the paper P is inserted into the sheet cassette 20 from the paper insertion opening 23a of the sheet cassette 20 mounted on the sheet supply unit B. Then, while being guided by the guide plates 25a and 25b and the resin spring 26, the sheet P is fed from the sheet delivery port 23b to the laminating unit C in a state where the sheet P is sandwiched between the adhesive sheets S1 and S2.

  In this way, the paper P sent out together with the adhesive sheets S1 and S2 is nipped by the pair of nipping rollers 30, thereby forming a laminated body R laminated by the adhesive sheets S1 and S2, and the cutting portion D. Sent out.

  In the cutting part D, the penetrating / separating mechanism 46 is activated and the vertical cutter blade 43 penetrates the laminate R immediately before the laminate R is sent out. Specifically, a motor (not shown) of the penetration / separation mechanism 46 rotates to rotate the disc cam 46d to move the vertical cutter blade 43 to a position where it passes through the laminate R.

  Then, the stack R sent out thereafter is the edge in the X direction of the paper P (when a stack R without an edge is selected) or the outside of the paper P (when a stack R with an edge is selected) in the Y direction. Cut into pieces.

  In the laminating apparatus 1 of this embodiment, a so-called triangular blade vertical cutter blade 43 is used, and the laminate R is pressed against the vertical cutter blade 43 by the moving force of the adhesive sheets S1 and S2 itself, and the laminate R is pushed through. To do. Therefore, a vertical force is generated at the contact portion between the vertical cutter blade 43 and the laminated body R, and the laminated body R tends to rise.

However, in the laminating apparatus 1 of the present embodiment, a holding portion 85 that holds the laminated body R is provided between the holding roller 30 and the vertical cutter blade 43 to solve this problem. That is, in the laminating apparatus 1 of the present embodiment, a pressing bar 35 is provided in the immediate vicinity of the driven roller 31, and a device for preventing the stacked body R from being lifted by the pressing bar 35 is devised.

  As can be conceptually understood from FIGS. 19 and 20, in the laminating apparatus 1 of the present embodiment, a pressing bar 35 is provided in the immediate vicinity of the driven roller 31, and the laminated body R that has come out of the holding roller 30 is pressed. It is sandwiched and held between the bar 35 and the floor-shaped receiving surface 81. Further, since the pressing bar 35 is pressed against the receiving surface 81 by the spring 37, the laminated body R is pressed against the receiving surface 81 by the force of the spring 37. Since the presser bar 35 is provided at a position immediately before the vertical cutter blade 43, the lift of the laminate R due to contact with the vertical cutter blade 43 is prevented by the presser bar 35, and the laminate R is cut smoothly. It will be done.

Further, in the laminating apparatus 1 of the present embodiment, countermeasures are also taken for lateral blurring of the vertical cutter blade 43.
That is, in the laminating apparatus 1 of the present embodiment, the vertical cutter blade 43 is removably attached via the cutter holder 50, and the vertical cutter blade 43 is cut at an appropriate position according to the size of the paper P. It is possible to move to perform.
Therefore, it is difficult to increase the rigidity of the peripheral portion of the vertical cutter blade 43, and the vertical cutter blade 43 tends to be laterally shaken. Here, when the vertical cutter blade 43 is touched sideways, the cutting edge cannot be brought into contact with the laminated body R vertically, and the sharpness is remarkably lowered.

  In order to solve this problem, the laminating apparatus 1 according to the present embodiment is provided with a projecting portion 59a projecting outward from the main body portion 55 of the cutter holder 50, and the friction member 80 is attached to the back side of the projecting portion 59a. In addition, a structure in which the reaction force generating member 75 is brought into contact with the front surface 75b is employed.

  In the laminating apparatus 1 of the present embodiment, there is a friction member 80 on the back side of the cutter holder 50, and this friction member 80 is in contact with the reaction force generating member 75, so the cutter holder 50 tries to move in the X direction. At this time, friction is generated between the friction member 80 and the reaction force generation member 75, thereby preventing the cutter holder 50 from moving. Therefore, in the laminating apparatus 1 according to the present embodiment, the horizontal blur of the vertical cutter blade 43 is small, and the laminate R is smoothly cut.

  In the laminating apparatus 1 of the present embodiment, the overhanging portion 61a is provided in the main body portion 55, and the friction member 80 is provided in the overhanging portion 61a. However, the friction member may be provided on the entire back surface of the main body portion 55. Conversely, a configuration in which a friction member is provided on the reaction force generating member 75 side is also possible.

When the laminate R is fed out and advances to a predetermined position in the Y direction of the paper P, the laminate R is cut in the X direction when the predetermined position of the laminate R reaches the cutting position by the horizontal cutter blade 41a. The desired laminate R is completed.
In addition, after the cutting position of the laminated body R by the horizontal cutter blade 41a for separating the laminated body R from the laminating apparatus 1 is not cut in the Y direction by the vertical cutter blade 43, the laminating apparatus is used by the vertical cutter blade 43. The tip portion of the laminate R left in one example is not divided into three in the X direction, and there is an effect that the next handling becomes easy.

  When the lamination process is repeated, the vertical cutter blade 43 becomes dull, and the laminate R is not smoothly cut in the Y direction. In that case, it is necessary to replace the vertical cutter blade 43, but according to the laminating apparatus 1 of the present embodiment, the replacement of the vertical cutter blade 43 is extremely easy and safe.

When replacing the vertical cutter blade, the top cover of the laminating apparatus 1 is removed, the swinging arm 33 is swung upward, the driven roller 31 and the pressing bar 35 are released, and the sheet cassette 20 is taken out. Secure space.
Then, contrary to the procedure for attaching the vertical cutter blade 43, the operating member 62 of the mounting member 52 is raised forward, and the engagement between the pressing portion 67 of the engaging claw 63 and the engaging wall 58e of the base member 51 is released. . Further, the operating member 62 of the mounting member 52 is raised forward, and the moving member 56 is pushed into the main body side. As a result, the engagement between the engagement member 58f in the width direction of the pedestal member 51 and the engagement wall 62g of the mounting member 52 is released, and the mounting member 52 can be slid in the X direction. Protrudes to reach the vicinity of the cutting edge of the vertical cutter blade 43 provided on the main body 55, and surrounds and covers the vertical cutter blade 43. Therefore, even if an operator accidentally touches the blade edge, no injury will occur.
Next, the mounting member 52 is moved in the X direction along the slide track portion 58 of the base member 51, and the mounting member 52 is removed from the base member 51.

It is also possible to use a structure in which the fitting portion is bent as a hinge.

  The cover member 72 of the cutter holder 50 uses a plate-like member in the present embodiment, but a “U” -shaped cover member 86 as shown in FIG. 21 or a “C” -shaped cover member 87. It can also be considered.

  The track shape of the pedestal member 51 is arbitrary, may be a more complicated shape, and may be a simpler shape.

  Further, the blade mounting structure using the cutter holder described above is not limited to the laminating apparatus, and can be employed in all kinds of apparatuses.

  In the laminating apparatus 1 of the present embodiment, the holding portion 85 is provided immediately before the vertical cutter blade 43, and the presser bar 35 and the floor-shaped receiving surface 81 are adopted as the constituent elements of the holding portion 85. As a member constituting the holding portion 85, a plate-like member 88 as shown in FIG. 22A can be adopted instead of the rod-like member such as the pressing bar 35 described above. The plate-like member may be a single layer. For example, a steel rigid portion 88a and a low friction member 88b typified by polytetrafluoroethylene are laminated, and a laminate is formed on the low friction member side. A configuration that suppresses R can also be adopted.

  Further, as shown in FIG. 22B, a plate-shaped member 89 having a substantially triangular cross-section or an arc-shaped upper surface along the driven roller 32 is used to hold the laminate R in a wider range. Is also possible.
