Description

  The present invention relates to a recording apparatus including a winding mechanism for winding a recorded recording medium.

  2. Description of the Related Art Conventionally, recording devices such as printers, copying machines, and facsimiles are widely used as output devices for recording on a recording medium such as recording paper. As the recording medium, various materials such as paper, plastic and cloth can be used. Particularly in large format printing, it is common to record images on a continuous recording medium such as roll paper.

  As a recording apparatus that performs large format printing, a printer unit that records on a recording medium based on recording information, a winding mechanism that winds up the recorded recording medium, and a cutting unit that cuts the recorded recording medium Is known. This type of recording apparatus performs recording while pulling out the recording medium wound in a roll shape into a strip shape, and discharges the recorded recording medium. There are two methods for processing a recorded medium: a method in which a recorded medium is cut at a predetermined size by a cutting means disposed in the printer unit, and a recorded medium to be recorded outside the printer unit. There is a method of winding in a roll shape with an equipped winding mechanism.

  The latter method of winding into a roll is particularly suitable when a large amount of recording is performed, and can save the user from having to pick up printed matter on the recording device. In addition, there is an advantage that intermittent work can be avoided for the user. Generally, the printed matter that has been continuously wound is sent to a separation work process such as a work table and separated one by one.

  A recording apparatus provided with the winding mechanism and cutting means as described above is disclosed in Patent Document 1. In a recording apparatus described in Patent Document 1, a printer unit (image forming unit) including a recording unit (recording head) and a conveyance roller that conveys a recording medium is supported by a stand. Below the printer unit, a paper feed table (paper feed mechanism) that supports and feeds a roll-shaped recording medium is attached to a stand. A take-up mechanism is attached to the stand below the paper feed table. In the recording apparatus described in Patent Document 1, a recording medium inserted into a printer unit from a paper feed table is recorded by a recording unit while being conveyed by a conveyance roller. Thereafter, the recording medium is continuously wound by the winding mechanism. Thereafter, the recording medium is cut at a desired position by cutting means arranged in the vicinity of the winding mechanism.

JP 2009-190292 A

  In the recording apparatus described in Patent Document 1, it is assumed that the recording medium is cut by the cutting means when the recording medium is wound by the winding mechanism by a predetermined length. That is, in the recording apparatus described in Patent Document 1, it is assumed that the winding diameter of the recording medium at the time of cutting in the winding mechanism is constant and the relative distance between the cutting means and the recording medium does not change. Therefore, for example, when the winding diameter at the time of cutting changes due to replacement with a recording medium of a different material, and the relative distance between the cutting means and the recording medium becomes long, the position of the cutting means is fixed, so the recording In order to cut the medium, it is necessary to forcibly pull the recording medium toward the cutting means. Therefore, it becomes difficult to cut the recording medium.

  SUMMARY An advantage of some aspects of the invention is that it provides a recording apparatus that can easily cut a recording medium even if the winding diameter of the recording medium in a winding mechanism changes.

  In order to achieve the above object, a recording apparatus according to the present invention includes a movable paper feed table that supports a continuous recording medium in a roll shape, and is disposed above the paper feed table, and is stripped from the paper feed table. A printer unit that records the drawn recording medium; a winding mechanism that is disposed below the paper feed base and that winds the recorded recording medium discharged from the printer unit; and the supply unit The recorded recording medium attached to the front end of the paper table and moved along with the movement of the paper feed table when the recorded recording medium is wound up by the winding mechanism by a predetermined length. And a cutting unit that cuts the recorded recording medium at the position.

  According to the present invention, the cutting unit moves to a position that reaches the recorded recording medium as the paper feed table moves, and cuts the recorded recording medium at that position. Therefore, even if the winding diameter of the recording medium in the winding mechanism changes, it is not necessary to forcibly pull the recording medium to the cutting part side by moving the cutting part when cutting the recording medium. Thereby, even if the winding diameter of the recording medium in the winding mechanism changes, the recording medium can be easily cut.

(Embodiment 1)
FIG. 1 is a perspective view of the recording apparatus of the present embodiment. FIG. 2 is a side view of the recording apparatus shown in FIG. As shown in FIG. 2, in the recording apparatus of the present embodiment, the recording unit 1 ejects ink based on the recording information while the conveying roller 2 conveys the roll paper 10 that is a continuous recording medium in a roll shape. Inkjet recording apparatus.

  First, the configuration of the recording apparatus of the present embodiment will be described with reference to FIGS. The printer unit 7 including the recording unit 1 and the conveyance roller 2 is attached to the upper part of the stand 8. The stand 8 includes a leg portion 8a that supports the printer unit 7 and a foot portion 8b that includes a caster 8c so that the recording apparatus can be easily moved. A paper feed table 4 that supports the roll paper 10 is attached to the leg portion 8 a below the printer unit 7. The paper feed table 4 can be manually moved in the horizontal direction, and is configured to be locked at each position to be described later. A cutting unit 5 is attached to the top end of the paper feed table 4. Further, a holding member 14 is attached to the front end of the paper feed table 4 below the cutting portion 5. A winding mechanism 3 is disposed below the paper feed table 4. In the present embodiment, the winding mechanism 3 is attached to the foot 8b.

  Next, a procedure for setting the roll paper 10 on the paper feed tray 4 will be described with reference to FIG. First, as shown in FIG. 2A, the paper feed base 4 positioned at a position close to the leg portion 8a (hereinafter referred to as a recording position) is moved forward (see arrow A in FIG. 2A). And is slid to a position preceding the printer unit 7. In the state shown in FIG. 2B, the paper feed table 4 is locked, and the roll paper 10 is set on the paper feed table 4 (see FIG. 2c). Thereafter, the paper feed table 4 is slid in the rear direction (see arrow B in FIG. 2D), and the paper feed table 4 is locked at the recording position, and the setting of the roll paper 10 is completed. In this way, the paper feed table 4 slides in the horizontal direction, so that it is possible to easily set the roll paper 10 that is generally heavy.

  Next, the operation content after the roll paper 10 is set on the paper feed tray 4 will be described.

  The roll paper 10 set on the paper feed table 4 is drawn out from the rear end of the paper feed table 4 by a paper feed roller 11 of the printer unit 7 and fed to the printer unit 7. Thereafter, the roll paper 10 is conveyed to a position immediately below the recording unit 1 by a conveyance roller 2 disposed in front of the paper supply roller 11. When the roll paper 10 is conveyed to just below the recording unit 1, the leading edge of the roll paper 10 is detected by the sensor 6 attached to the recording unit 1. The recording unit 1 determines the recording start position on the roll paper 10 based on the detection result of the sensor 6. At this time, an accurate recording start position cannot be determined unless the leading edge of the roll paper 10 is cut into a linear shape. Therefore, in the present invention, when the leading end of the roll paper 10 is not linear, the roll paper 10 is cut by the cutting unit 5 attached to the top of the leading end of the paper feed table 4 before recording on the roll paper 10. . Hereinafter, this cutting operation will be described with reference to FIGS. FIG. 3 is a diagram illustrating a configuration of the cutting unit 5. FIG. 3A is a perspective view of the cutting portion 5. FIG. 3B is a cross-sectional view of the cutting part 5. FIG. 4 is a side view showing a state in which the leading edge of the roll paper 10 is cut.

  The cutting unit 5 is attached to a rail 9 provided at the upper end of the paper feed table 4. A slit 5 b is formed in the cutting part 5. When the leading edge of the roll paper 10 set on the paper feed table 4 is manually brought into contact with the rail 9, the two rotatable round teeth 5a sandwich the roll paper 10 with the slits 5b. When the cutting part 5 slides along the rail 9 in this state, a shearing force is generated, and the roll paper 10 is cut in the width direction by the generated shearing force. As a result, the leading edge of the roll paper 10 has a linear shape, so that the recording start position on the roll paper 10 can be accurately detected.

  Next, an operation after the recording unit 1 records on the roll paper 10 will be described. In the recording apparatus of the present embodiment, post-recording operation modes include a post-recording cut mode and a winding recording mode.

  In the post-recording cut mode, the roll paper 10 that has been recorded in the recording unit 1 is transported by the transport roller 2 to the lower part of the cutter 12 disposed downstream of the recording unit 1 in the transport path of the roll paper 10. The When the cutter 12 scans in the width direction of the roll paper 10, the roll paper 10 is cut and discharged.

  The winding recording mode will be described with reference to FIG. FIG. 5 is a side view for explaining the operation content of the winding recording mode.

  In the winding recording mode, first, the recorded roll paper 10 is discharged from the printer unit 7. The leading end of the discharged roll paper 10 is fixed to the winding mechanism 3. Thereafter, the roll paper 10 discharged from the printer unit 7 is conveyed to the winding mechanism 3 (see arrow C in FIG. 5A). When all the winding operations are completed, that is, when the roll paper 10 is wound up by the winding mechanism 3 by a predetermined length, the cutting position of the roll paper 10 is located in front of the cutting unit 5. Thereafter, the paper feed table 4 is moved in the forward direction (see arrow A) so that the cutting unit 5 reaches the position where it reaches the roll paper 10, and is fixed at that position (see FIG. 5B). Then, the surface opposite to the recording surface of the roll paper 10 is brought into contact with the rail 9. Subsequently, the roll paper 10 is held by the holding member 14 provided at the lower end of the front end of the paper feed table 4. In the present embodiment, the holding member 14 includes two clips that hold both ends of the roll paper 10 in the width direction below the cut portion of the roll paper 10 (winding mechanism 3 side). One clip is slidable in the width direction of the roll paper 10. Thereafter, the cut paper 5 is cut along the rail 9 to cut the roll paper 10 (see FIG. 5C).

  As described above, according to the recording apparatus of the present embodiment, the cutting unit 5 moves to a position that reaches the recorded roll paper 10 as the paper feed table 4 moves, and cuts the roll paper 10 at that position. To do. Therefore, even if the winding diameter of the roll paper 10 in the winding mechanism 3 changes, it is not necessary to forcibly pull the roll paper 10 toward the cutting part 5 side by moving the cutting part 5 when the roll paper 10 is cut. Thereby, the roll paper 10 can be easily cut.

  Further, according to the present embodiment, since the cutting unit 5 is attached to the upper end of the paper feed table 4, after the roll paper 10 is cut by the cutting unit 5, the paper feed table 4 hangs down from the printer unit 7. It is not blocked by the roll paper 10. Therefore, the roll paper 10 after the cutting operation can be exchanged smoothly.

  Further, according to the present embodiment, by providing the holding member 14 that can hold the roll paper 10, the roll paper 10 is fixed when the roll paper 10 is cut, so that the roll paper 10 is easily cut. In addition, after the cutting, the recording surface of the roll paper 10 hangs down and touches the floor or the like, thereby preventing scratches and dirt from being attached.

  Further, according to the present embodiment, since the cutting unit 5 is moved in conjunction with the slide operation of the paper feed table 4, it is not necessary to separately provide a mechanism for moving the cutting unit 5. For this reason, it is possible to reduce the size and cost of the recording apparatus.

(Embodiment 2)
FIG. 6 is a perspective view of the recording apparatus of the present embodiment. FIG. 7 is a side view of the recording apparatus shown in FIG. The recording apparatus of the present embodiment is an ink jet recording apparatus in which the recording unit 21 discharges ink based on recording information while the transport roller 22 transports a roll medium 30 that is a recording medium such as vinyl chloride.

  In the recording apparatus of the present embodiment, the printer unit 27 including the recording unit 21 and the conveyance roller 21 is attached to the upper part of the stand 28. A heater 33 is attached to the tip of the printer unit 21. The heater 33 dries the ink with heat in order to fix the ink attached to the recording surface of the roll medium 30 by the recording unit 21.

  In the present embodiment, the procedure for setting the roll medium 30 on the paper feed table 24 is the same as that of the recording apparatus of the first embodiment, and thus detailed description thereof is omitted. In the recording apparatus of the present embodiment, a heater 33 is attached to the tip of the printer unit 27. For this reason, when the paper feed tray 24 is pulled forward by the same distance as the paper feed tray 4, the heater 33 is positioned above the paper feed tray 24, making it difficult to set the roll medium 30. Therefore, it is preferable that the slide distance of the paper feed table 24 in the horizontal direction is longer than that of the paper feed table 4.

  After the roll medium 30 is set on the paper feed tray 4, the roll medium 30 is fed to the printer unit 27 in the same manner as the recording apparatus of the first embodiment, and the recording unit 21 in the printer unit 27 inks the roll medium 30. Is discharged. Thereafter, the heater 33 dries the ink attached to the recording surface of the roll medium 30. This series of operations is performed while winding the roll medium 30 in the arrow D direction (see FIG. 7) by the winding mechanism 23. The roll media 30 immediately after drying is easily deformed because it is heated by the heat of the heater 33. For this reason, if the roll media 30 is cut immediately after drying, it is difficult to cut the roll media 30 in a straight line. Therefore, it is necessary to cut the roll media 30 after the temperature of the roll media 30 is lowered. When a cutting means for cutting the roll medium 30 is disposed in the vicinity of the printer unit 27, the cutting means needs to have a heat resistant structure in order to protect it from the heat of the heater 33. In addition, after the roll medium 30 is dried by the heater 33, it is necessary to transport the roll medium 30 in the direction opposite to the arrow D, which takes time. On the other hand, in the recording apparatus of the present embodiment, a cutting unit 25 having the same configuration as the cutting unit 5 is attached to the upper end of the paper feed base 24 that is sufficiently separated from the printer unit 27. For this reason, it is not necessary to provide the cutting part 25 with a heat-resistant structure for protecting it from the heat of the heater 33, and after the roll medium 30 is dried, it can be cut without changing the transport direction of the roll medium 30. Therefore, it does not take extra time when the roll media 30 is cut.
