  When the conveyance roller of the printer apparatus pulls the leading edge of the sheet, if the sheet is pulled obliquely with respect to the traveling direction, the sheet may be skewed and the sheet may be wrinkled or clogged. In particular, when a sheet wound in a roll shape is used, the portion wound around the core of the sheet is restrained so as not to move in the width direction, and the displacement in the width direction gradually increases with the sheet feeding at the conveyance roller. Accumulation is more likely to cause an accident such as sheet deformation due to skew than a printer that uses a single sheet. Further, when the conveying roller is a grid roller having a high gripping force, the sheet sandwiched between the rollers does not slip in the width direction, and the possibility of sheet jamming or the like is further increased.

  Therefore, there is a technical problem to be solved in order to prevent the skew of the sheet at the time of printing and to eliminate the possibility of sheet deformation and sheet jamming, and the present invention solves the above problem. Objective.

The present invention is proposed in order to achieve the above object, and in a printer device for printing a printing sheet wound in a roll shape to the printer unit side by a conveying means and printing the printing sheet . the transport means of the printing sheet, a first pinch roller opposed to the grid roller and the grid roller which is driven to rotate, the elastic contact means for relatively elastic contact with the rollers, positioned downstream of said grid roller has been made and a second pinch roller for elastic contact to one or more of the conveying roller and the conveying roller which is driven to rotate, a pair of left and right guide for regulating the width direction of the printing sheet, the said grid roller first It sends a print sheet while releasing the elastic contact between first pinch rollers, after sending the length corresponding to the print area length data, the grid rollers and the first The pinch roller by elastic contact, comprising a control means for printing the print sheet while pulling back, the right and left over the transport path the entire length of the printing sheet positioned between the first pinch rollers and the transport rollers A printer apparatus characterized by providing a pair of guides is provided .

  Further, the present invention provides a printer device in which the printing means is a thermal head provided with an elevating mechanism, and printing is performed by bringing the thermal head into pressure contact with the printing sheet in the pulling back process of the printing sheet.

  Further, a control means for interposing a torque limiter on the conveying roller and driving at a reduced peripheral speed from a roller on the leading side in the feeding direction of the conveying roller row including the grid roller to a lower roller at the time of feeding and pulling back. And providing a printer device that applies tension to the printing sheet during sheet conveyance.

According to the present invention, the printing sheet is moved along the conveying path in a state where the printing sheet is sandwiched between the conveying roller and the second pinch roller and the elastic contact between the grid roller and the first pinch roller is released. It is sent to a position corresponding to the print range length data. Thereafter, the first pinch roller is brought into elastic contact with the grid roller, and printing is performed while the printing sheet is pulled back.
In the present invention, before the printing sheet is sandwiched between the grid roller and the first pinch roller, the printing sheet is placed between a pair of left and right guides on the conveyance path, that is, between the first pinch roller and the conveyance roller. It is conveyed along a guide provided over the entire conveying path. As a result, since the position of the sheet in the width direction is restricted, the sheet maintains straightness, and there is no risk of skew or bending deformation.
As described above, the printer device of the present invention guides the width direction of the printing sheet when the printing sheet having a length corresponding to the printing range length data is sent from the printing sheet wound in a roll shape. Since the printing sheet is straightened and the conveyance direction is reversed, the printing sheet is pulled back by the grid roller, and printing is performed in a state where the leading edge of the sheet is not restrained, so that the sheet is printed while being pulled out from the sheet roll. Compared to the above, the possibility of vertical streaking and sheet jamming due to the skew of sheets and the accumulation of directional displacement is extremely reduced.

  In addition, only when the sheet is pulled back and printed, the thermal head is pressed against the sheet, so that the thermal head does not receive resistance when the sheet is fed, and the sheet is smoothly fed while maintaining the straightness of the sheet. Can do.

  In addition, a torque limiter is installed on the conveyance roller other than the grid roller, and the printing sheet is tensioned by controlling the drive by reducing the peripheral speed from the first roller in the feed direction to the lower roller. The straightness is maintained. In addition, since the tension is applied, the printing sheet length between the grid roller and the thermal head is kept constant, so that the printing position is not misaligned, and in particular, a plurality of ink ribbons (thermal heads) are used. The print quality on the sheet can be improved.

This invention provides a printer apparatus for performing printing on the printing sheet by transporting the printing sheet wound into a roll on the printer unit side by the conveying means, the conveying means of the printing sheet is rotated Grid roller, first pinch roller facing the grid roller, elastic contact means for relatively elastically contacting both rollers, and one or a plurality of conveying rollers disposed downstream of the grid roller and driven to rotate and a second pinch roller for elastic contact to the conveying roller, consists of a pair of guides for regulating the width direction of the printing sheet, while releasing the elastic contact between the said grid roller first pinch roller It sends the print sheet, after having sent a length corresponding to the printing range length data, by elastic contact with the said grid roller first pinch rollers, pull the sheet for printing In and comprising a control means for printing while, by providing the first pinch roller and the pair of right and left guide over the transport path the entire length of the printing sheet which is located between the conveying roller, during printing The purpose of preventing the skew of the sheet and eliminating the risk of sheet deformation and sheet jamming has been achieved.

  FIG. 1 shows a printer device 1 that performs two-color printing, surface lamination processing and cutting processing on an adhesive sheet with release paper, the first printer unit 2 on the left side, the second printer unit 3 on the upper left side, and the upper surface Laminate processing part 4 is arranged on the right, and these three mechanism parts 2, 3, and 4 are hinged to the frame, respectively, and as shown in FIG. Can be exposed. In addition to the above configuration, each mechanism part 2, 3, 4 is hinged to the frame on one side in the width direction of the adhesive sheet with release paper, and the inner surface side is exposed by pulling up one end and inverting it. You may make it make it.

  FIG. 3 is a front view of the printer apparatus 1 with the front cover removed, and FIG. 4 is a simplified front view in which portions other than the main parts are not displayed. As shown in FIG. 4, the lower side of the center portion of the frame 5 is a sheet roll storage chamber 6, and the adhesive sheet roll SR with release paper attached to the sheet roll support shaft 7 is supported in the air. A first transport path 8 is arranged from the left to the top of the sheet roll storage chamber 6, and this first transport path 8 is a semicircular shape that reverses rightward from the left to the top of the sheet roll storage chamber 6. The reversing curved surface portion 8a and the non-reversing curved surface portion 8b extending horizontally from the upper end of the reversing curved surface portion 8a toward the right side of the frame 5, and below the first conveying path 8 are the first conveying path 8 and A second transport path 71 is arranged in parallel.

  The first conveyance path 8 is exposed at the apex of the motor-driven conveyance roller 9 (9 ') and the driven guide roller 10 from the back side through slits formed at important points, and is at the entrance on the sheet roll storage chamber 6 side. The second roller counted from the grid roller 11 is a grid roller 11 in which the surface of a hard material such as metal or ceramic is subjected to anti-slip processing, and the adhesive sheet with release paper is used in a printing process described later by the grid roller 11 driven by a motor. The feed amount is controlled precisely.

  The pinch roller 12 shown in FIG. 5 is in elastic contact with the motor-driven transport roller 9 (9 ′) below the first transport path 8, and the pinch roller 12 facing the grid roller 11 is swung by a cam 31. It is supported by the link 32 to be driven. In the feeding process other than the printing process, the pinch roller 12 is separated from the grid roller 11, and is controlled so as to elastically contact the grid roller 11 only in the printing process by the control unit. That is, the conveyance roller 9 (9 ') and the pinch roller 12 sandwich the release sheet-attached adhesive sheet S and feed it in the forward direction (downstream from the release sheet-attached adhesive sheet roll SR). In addition, the adhesive sheet S with release paper is fed in the opposite direction with the release sheet-attached adhesive sheet S sandwiched between the grid roller 11 and the pinch roller 12.

  A shaft B in the vicinity of the sheet roller SR in FIG. 4 is rotatably fixed to the frame 5 by an arm C and is in contact with the sheet S. On the other hand, a sensor (not shown) is disposed in the vicinity of the arm C, and detects the angle of the arm C due to the contact between the shaft B and the sheet S. By controlling the rotation of the sheet roll SR according to this detection angle, in cooperation with the shaft B, the sheet S is given a moderate slack when the sheet S is fed, and the extra slack of the sheet S is absorbed when the sheet is rewound. By doing so, a constant amount of slack is always secured.

  FIG. 6 shows a portion of the transport roller 9 (9 ′), and the shaft 33 of the transport roller 9 (9 ′) disposed on the back surface of the first transport path 8 is connected to a torque limiter 35 integrated with the belt pulley 34. In addition, power is transmitted from the drive mechanism via the belt 36 that is hung on the belt pulley 34. The pinch roller 12 is rotatably mounted on the pinch roller shaft 37, and both ends of the pinch roller shaft 37 are engaged with guide grooves 39 formed in a pair of side plates 38 which are constituent parts of the frame 5, A tension coil spring 40 is applied to both end portions of the pinch roller shaft 37 and the side plate 38 to elastically contact the pinch roller 12 with the transport roller 9 (9 ′). On the first conveyance path 8 located between the pinch roller 12 and the conveyance roller 9 (9 ′), a pair of left and right sheet side surface guides 41 that regulate the position in the width direction of the sheet S are provided, and the sheet S is configured to advance straight along the sheet side guide 41.

  In FIG. 4, the conveyance roller 9 ′ closest to the sheet roll storage chamber 6 and the other conveyance rollers 9 downstream from the grid roller 11 are driven by separate motors (not shown), respectively, Driven in the relationship of the peripheral speed of the transport roller 9> the peripheral speed of the transport roller 9 ′. The difference in peripheral speed between the rollers is absorbed by the torque limiter 35, and the sheet S is fed under a certain tension. Further, the elastic contact force of the pinch roller 12 to the rollers 9 'and 9 is set to be relatively light so as not to prevent the sheet S from being corrected in direction by the sheet side guide 41 when the sheet is fed.

  On the other hand, in the printing process, since the direction of the sheet has already been corrected in the straight direction, the grid roller 11 is strongly pressed against the sheet S and the sheet S is rewound without slipping. At this time, the relationship between the peripheral speeds of the rollers is as follows: transport roller 9 ′> grid roller 11> transport roller 9, and the peripheral speed gradually decreases from the first roller of the rewinding to the downstream roller. The sheet S is tensioned before and after the grid roller 11 and is rewound in a straight line.

  In FIG. 4, the first printer unit 2 arranged in a vertical posture facing the left end of the inverted curved surface portion 8a of the first conveyance path 8, and the first printer unit arranged in a horizontal posture facing the upper end of the inverted curved surface portion 8a. The two printer units 3 have the same configuration, and a flat type thermal head 14 is attached to a printer unit housing 13 that is a receiving base for the ink ribbon roll IR. In the printing process, the thermal head 14 has a cam mechanism (not shown). 4) from the floating position in FIG. 4 to the lowered position in contact with the guide roller 10, and thermal transfer printing is performed on the surface of the adhesive sheet S with release paper. For example, two-color printing of black and red can be performed by attaching a black ink ribbon to the first printer unit 2 and attaching a red ink ribbon to the second printer unit 3.

  By disposing the planar thermal head 14 so as to face the reversing curved surface portion 8a of the first transport path 8, the lateral width of the apparatus can be suppressed as compared with the case where a plurality of thermal heads are disposed on the straight transport path, and the platen roller Alternatively, since there is no need to locally raise the sheet by ribs or the like, satisfactory print quality can be obtained with a planar thermal head instead of an end face type thermal head, and tunneling may occur where the sheet floats from the release paper. Absent.

  The first printer unit 2 and the second printer unit 3 have a shaft hole 15 at the upstream end engaged with a shaft 16 provided in the main body frame 5, and are latched with a hook shape and a wedge shape as shown in FIG. 17 is fixed to the frame 5 in a closed state. By operating the latch 17 biased to the lock position by the spring in the unlocking direction, the first printer unit 2 and the second printer unit 3 can be opened by rotating about the shaft 16 as a fulcrum. The latch 17 is automatically engaged and fixed to a locking portion (not shown) of the frame 5.

  As shown in FIG. 4, a pair of front and rear open bearings 18 are formed on the left and right side surfaces of the printer housing 13, and the core of the ink ribbon roll IR is received by the open bearings. Gears are arranged in the vicinity of each of the pair of open bearings 18, the upstream side gear (the side near the sheet roll storage chamber) is the take-up gear 19, and the downstream side gear is the supply gear 20. 21 is connected to a gear G provided at the end of the core of the ink ribbon roll IR.

  A pair of front and rear intermediate gears 21 are attached to the tips of swing levers 22 coaxial with the shafts of the take-up gear 19 and the supply gear 20, respectively, and are stretched over the other ends of the two front and rear swing levers 22. Due to the spring force of the coil spring 23, the intermediate gear 21 is in elastic contact with the gear G at the end of the ink ribbon core. A torque limiter type brake (not shown) is connected to the shaft of the supply gear 20, and an appropriate back tension is applied to the ink ribbon when winding the ink ribbon.

  A link portion 22a extending in a direction approaching each other is formed at an intermediate portion between the two front and rear swing levers 22, and is a link attached to the side surface of the printer unit housing 13 by an axis A separately from the swing lever 22. A pin at the tip of the lever 24 engages with an elongated hole at the tip of the link portion 22a of the two swing levers 22 to constitute an interlocking link mechanism for the two swing levers 22.

  As shown in FIG. 4, when the first printer unit 2 and the second printer unit 3 are closed, the intermediate gear 21 is urged outward by the spring force of the tension coil spring 23, and the end of the core of the ink ribbon IR. The rear end of the link lever 24 is in contact with a first stopper pin 25 provided on the main body frame 5 and is prevented from rotating counterclockwise. That is, the intermediate gear 21 cannot move away from the gear G of the ink ribbon roll IR, and power is reliably transmitted from the take-up gear 19.

  On the other hand, in the state where the first printer unit 2 and the second printer unit 3 are rotated about the axis as shown in FIG. 7 and the surface on the thermal head side is exposed, the rear end of the link lever 24 is provided on the frame 5. The two swing levers 22 are rotated counterclockwise by hitting the two stopper pins 26, and the link lever 24 is rotated in the direction in which the intermediate gear 21 approaches against the spring force of the tension coil spring 23. As a result, the intermediate gear 21 is separated from the gear G of the ink ribbon roll IR, and the ink ribbon roll IR can be attached and detached.

  The laminating section 4 disposed in the upper right part of the main body is a unit that presses the laminating sheet L onto the surface of the adhesive sheet S with release paper printed by the printer units 2 and 3 using the laminate sheet roll LR with release paper. In addition, instead of the thermal head 14 of the printer units 2 and 3, a pressure roller 27 that moves up and down by a cam mechanism is provided, and the rotation direction when opening and closing is opposite to that of the first printer unit 2 and the second printer unit 3. Also, since the winding diameter of the laminate sheet roll LR with release paper is large, the number of intermediate gears is larger than that of the intermediate gear 21 of the printer units 2 and 3, and the basic configuration is the same as that of the first printer unit 2 and the second printer unit 3. Due to the same structure, the tension coil spring 23 'and the link mechanism similar to those of the printer units 2 and 3, the intermediate gear 21' is separated from the core gear G of the laminate sheet roll LR with release paper when opened, and the intermediate gear when closed. 21 'elastically contacts the gear G of the laminate sheet roll LR with release paper.

  The laminate sheet with release paper comprises a first adhesive layer a, a laminate film layer b, a second adhesive layer c, and a release paper layer d as shown in FIG. The force is set so as to be larger than the adhesive force of the second adhesive layer c. Therefore, when the laminate sheet with release paper and the adhesive sheet S with release paper pulled out from the laminate sheet roll LR with release paper pass through the pressure roller 27 in a laminated state, the first adhesive layer a and the laminate film layer b Only the laminate sheet L is adhered to the surface of the pressure-sensitive adhesive sheet S with release paper, and only the release paper is taken up by the take-up roller as shown in FIG.

  A cutter blade 28 for cutting the laminate sheet L is disposed slightly downstream of the guide roller 10 of the first conveyance path 8 facing the pressure roller 27 of the laminating unit 4, and the cutter blade is used during the laminating process. 28 is driven obliquely downward toward the upstream direction of the first conveying path 8 to cut the end portion of the laminate sheet L attached to the surface of the adhesive sheet S with release paper.

  A path switching flap 51 is provided immediately after the cutter blade arrangement position of the first conveyance path 8, and a cutting processing unit 61 is disposed on the lower right side of the path switching flap 51. Further, the right end of the second conveyance path 71 disposed below the first conveyance path 8 faces the path switching flap 51.

  The path switching flap 51 switches the path of the release sheet-attached adhesive sheet S sent on the first transport path 8 to the end direction of the first transport path 8 or the cutting processing unit 61 direction. 4), the position is switched between the horizontal position in FIG. 4 and the position rotated clockwise by a predetermined angle, with the shaft 52 at the front and rear intermediate portion as a fulcrum.

  The route switching flap 51 has three layers of upper, middle, and lower seat passages 53, 54, and 55 formed therein. The upper seat passage 53 and the lower seat passage 55 are horizontal, and the middle seat passage 54 is inclined downwardly to the right. The middle sheet passage 54 and the lower sheet passage 55 are enlarged on the side that becomes the entrance of the adhesive sheet S with release paper, that is, on the left side in the middle sheet passage 54 and on the right side in the lower sheet passage 55. Thus, the adhesive sheet S with release paper can be reliably introduced.

  Immediately after the path switching flap 51, a motor-driven ridge 56 is arranged, and when the printed adhesive sheet with release paper S is sent to the cutting processing section through the middle sheet path 54 of the path switching flap 51, The pressure-sensitive adhesive sheet S with release paper is cut at the end of the printing range of the pressure-sensitive adhesive sheet S with release paper.

  The cutting processing unit 61 has the same configuration as a normal cutting plotter and includes a cutting head 62 that is controlled to move in the width direction of the sheet. Based on the cutting data, the cutting processing unit 61 removes the adhesive sheet S with release paper by a feeding mechanism by the grid roller 63. While moving in both the front and rear directions, the cutting head 62 is driven in the sheet width direction to cut only the pressure-sensitive adhesive sheet of the pressure-sensitive adhesive sheet S with release paper according to the cutting data.

  Next, a series of operations of the printer apparatus 1 having the above configuration will be described. First, as shown in FIG. 4, when the tip of the release sheet adhesive sheet S of the release sheet roll SR is inserted into the entrance of the first transport path 8, the first sheet sensor 29 disposed at the entrance detects the insertion of the sheet. Then, the motor of the feeding mechanism is activated, the sheet is sandwiched by the conveying roller 9 ′ and the pinch roller 12, and is fed upward along the first conveying path 8. At this time, the pinch roller 12 facing the grid roller 11 that is the second conveying roller from the entrance floats, and the sheet is fed by the conveying roller 9 (9 ') excluding the grid roller 11.

  As shown in FIG. 8, when the leading edge of the release sheet-adhesive sheet S reaches the position of the second sheet sensor 30 disposed just before the pressure roller 27 of the laminating section 4, the second sheet sensor 30 The feed is stopped by the detection signal, and thereafter, as shown in FIG. 9, the pinch roller 12 facing the grid roller 11 is brought into elastic contact with the grid roller 11 to sandwich the adhesive sheet S with release paper.

  Since the conveyance path length from the position of the second sheet sensor 30 to the position of the thermal head 14 of the second printer unit 3 is known, the grid roller 11 is driven to move the sheet downstream according to the sheet length data to be printed. Send or rewind upstream. FIG. 10 shows an example in which the pressure-sensitive adhesive sheet with release paper is sent downstream.

  Then, when the printing start point on the adhesive sheet with release paper is located immediately below the thermal head 14 of the second printer unit 3, the adhesive sheet S with release paper is rewound into the printing process as shown in FIG. enter. The first printer unit 2 with the black ink ribbon and the second printer unit 3 with the red ink ribbon each perform printing by bringing the thermal head 14 into pressure contact with the sheet surface under the control of the print control unit based on the print data. .

  In this way, before the sheet is sandwiched between the grid roller 11 and the pinch roller 12, the release sheet-attached adhesive sheet S is conveyed along the sheet side guide 41 on the first conveyance path 8 shown in FIG. The straightness of the seat is ensured. And, while printing while rewinding the adhesive sheet S with release paper while maintaining the straightness, compared with the configuration in which the sheet is printed while being pulled directly from the sheet roll SR by the grid roller, the skew of the sheet and the direction displacement are reduced. There is very little risk of vertical flaws and sheet jamming due to accumulation.

  When the printing is finished, the pinch roller 12 that is elastically in contact with the grid roller 11 is lifted, and after releasing the restraint of the sheet by the grid roller 11, the adhesive sheet S with release paper is sent downstream, and the process of FIGS. 8 and 9 Similarly, when the leading edge of the adhesive sheet S with release paper is detected again by the second sheet sensor 30, the pinch roller 12 facing the grid roller 11 is brought into elastic contact with the grid roller 11 to release the adhesive sheet S with release paper. From here, the tip of the adhesive sheet S with release paper is sent from here to the tip of the next conveyance roller 9 of the second sheet sensor 30.

  This is the end of the description of the printing process. The following is a description of the laminating process and the cutting process. As shown in FIG. 12, when the adhesive sheet S with release paper is sent, the laminating section 4 moves down the pressure roller 27 of the laminate processing section 4 and ends the lamination range of the adhesive sheet S with release paper. Until the pressure reaches the pressure roller position, the adhesive sheet S with release paper is sent downstream, and the laminate sheet is pressure-bonded to the surface of the printed adhesive sheet with release paper S. The leading end portion of the release sheet-attached pressure-sensitive adhesive sheet S passes through the horizontal upper sheet path 53 of the path switching flap 51 and is sent out from the right end of the first transport path 8.

  After the laminating process is completed, the pressure roller 27 of the laminating unit 4 is raised, and as shown in FIG. 13, the cutter blade 28 is driven obliquely downward toward the upstream side of the first conveying path 8, and the adhesive sheet S with release paper The end portion of the laminate sheet L attached to the surface of the sheet is cut.

  Next, reverse the sheet feeding direction, as shown in FIG. 14, rewind until the tip of the adhesive sheet S with release paper passes the path switching flap 51, rotate the path switching flap 51 clockwise, The entrance on the upstream side of the sheet passage 54 is lifted and opposed to the first conveyance path 8. Then, the feeding direction of the feeding mechanism is reversed again, and the adhesive sheet with release paper S is sent downstream.

  As shown in FIG. 15, the adhesive sheet S with release paper advances obliquely downward to the right through the middle sheet passage 54 of the path switching flap 51, and is sent to the cutting processing unit 61. When the end of the print range (including the margin) of the sheet based on the print data reaches the position of 鋏 56, the sheet feeding is stopped and the pinch roller 12 facing the grid roller 63 of the cutting processing unit 61 is lowered. Then, the pressure-sensitive adhesive sheet S with release paper is sandwiched, and the pressure sensitive adhesive 56 is driven to cut the pressure-sensitive adhesive sheet S with release paper.

  Subsequently, the sheet feeding direction is reversed, and as shown in FIG. 16, rewinding is performed until the leading end of the adhesive sheet S with release paper passes the path switching flap 51, and the path switching flap 51 is rotated counterclockwise. Return to the initial position. At this time, the rear end of the adhesive sheet S with release paper that has been cut and remains on the cutting processing unit 61 faces the entrance of the lower sheet passage 55 of the path switching flap 51, and as shown in FIG. The part 61 performs the cutting operation by reciprocating the cutting head 62 in the width direction of the sheet while switching the feeding of the adhesive sheet S with release paper in both forward and reverse directions, and the adhesive sheet S with release paper is directly under the first conveying path 8 Enters the second conveyance path 71 arranged in the area.

  When the cutting process is started on the printed adhesive sheet with release paper S, a new printing process is started on the first conveying path 8 side, and the above-described processes are executed from the beginning. In this way, the conveyance path is divided into the first conveyance path 8 and the second conveyance path 71, and each sheet can be independently fed, and the control means is used to perform cutting and the next sheet printing in parallel. By configuring, the overall processing speed is improved.

  When the cutting process is completed, the pinch roller 12 that is elastically in contact with the grid roller 63 of the cutting processing unit 61 is lifted, and the adhesive sheet S with release paper that has been subjected to the cutting process is transferred by the conveying roller 9 and the pinch roller 12 as shown in FIG. It is discharged outside.
