Description

  The present invention relates to a recording medium winding device for winding a recording medium output by an image recording device such as an ink jet printer.

  2. Description of the Related Art Conventionally, an image recording apparatus such as an ink jet printer performs image recording on a long recording medium such as a cloth, and a recording medium winding apparatus that winds the recording medium after image recording on a roll is known. In such a recording medium winding device, it is necessary to devise various ways to finish a rolled product with high quality without damaging the recording medium on which image recording has been performed.

  That is, when a long recording medium is wound on a roll, wrinkles or kinks may occur unless an appropriate tension is applied to the entire surface of the recording medium to be wound. For this reason, it is necessary to hold the recording medium horizontally while applying an appropriate tension to perform winding.

  Therefore, conventionally, as a recording medium winding device for winding a recording medium after image recording, a pair of rollers that sandwich the recording medium from both the image recording surface and the non-image recording surface are provided to hold the recording medium and perform recording. An apparatus for winding a medium is known (see, for example, Patent Document 1 and Patent Document 2).

  In addition, when the recording medium after image recording is wound up in a roll shape, there is a risk of damaging the image recording surface if the wound recording media come into contact with each other. When the recording medium is a fabric, When wound under tension, there is a risk that the cloth will rub against each other due to the force of the cloth returning to its original state. However, in this case, even if high-quality image recording is performed by the image recording apparatus, it is useless.

For this reason, there has been proposed a recording medium winding device that winds while winding an auxiliary material such as a slip sheet together with the recording medium so that the recording medium does not rub after being wound (for example, And Patent Document 3).
Japanese Patent Laid-Open No. 10-147462 JP 2001-72285 A JP-A-11-301892

  However, the recording medium immediately after image recording by an image recording apparatus such as an ink jet printer may not have dried ink on the image recording surface. When a recording medium is held by holding rollers sandwiched from both sides of the recording surface, the image recording surface comes into contact with the roller and the ink adheres to the roller, and the ink attached to the roller reattaches to the recording medium. There is a problem that the image recording surface of the recording medium may become dirty.

  Further, in the case of an apparatus for winding an auxiliary material such as a slip sheet while winding it together with a recording medium, conventionally, an auxiliary material roller around which the auxiliary material is wound is usually disposed below the winding roller. With this configuration, if the auxiliary material is exhausted during the winding operation of the recording medium, it may take time to replace the auxiliary material roller, and the recording medium may be wound without the auxiliary material and the image recording surface may be damaged. There is a problem that the image recording operation of the image recording apparatus may have to be interrupted in order to replenish the auxiliary material.

  Accordingly, the present invention has been made to solve the above-described problems, and an object thereof is to provide a recording medium winding device that can wind up a recording medium on which an image has been recorded with high quality. It is.

In order to solve such a problem, the invention described in claim 1 is a recording medium winding device for winding a long recording medium.
A take-up roller for taking up the recording medium, provided with a roller driving mechanism for driving the take-up roller,
The tension roller that applies a constant tension to the recording medium in contact with the non-image recording surface of the recording medium upstream of the recording medium conveyance direction from the take-up roller is provided, certain surfaces of the tension roller sticky material Formed by and
A sensor for detecting a slack amount of the recording medium is provided upstream of the tension roller in the recording medium conveyance direction, and a sensor moving mechanism for moving the position of the sensor in a direction orthogonal to the recording medium conveyance direction is provided. The roller driving mechanism is characterized in that winding of the recording medium by the winding roller is started in accordance with the amount of slackness of the recording medium detected by the sensor .

According to the first aspect of the invention having such a configuration, the tension roller disposed upstream in the recording medium conveyance direction with respect to the take-up roller driven by the roller driving mechanism has adhesiveness. By disposing the roller in contact with the non-image recording surface of the recording medium, the recording medium is supported and a certain tension can be applied.
Further, the winding of the recording medium by the winding roller is started based on the result detected by the sensor that detects the slack amount of the recording medium.

  According to a second aspect of the present invention, in the recording medium winding device according to the first aspect, the roller provided upstream in the recording medium conveyance direction from the winding roller is only the tension roller. It is a feature.

  According to the second aspect of the invention having such a configuration, the recording medium is supported, and the recording medium discharged from the image recording apparatus can be supported by one tension roller.

According to a fifth aspect of the present invention, in the recording medium winding apparatus according to any one of the first to fourth aspects, the auxiliary material wound together with the recording medium by the winding roller is wound. The auxiliary material roller is provided above the winding roller.

In the invention according to claim 5 having such a configuration, since the auxiliary material roller is provided above the take-up roller, the auxiliary material can be easily replaced and replenished. .

According to the first aspect of the present invention, the tension roller for applying tension to the recording medium discharged from the image recording apparatus supports the recording medium only from the non-image recording surface side. Even if the recording medium to be taken is a recording medium that is discharged immediately after image recording and the ink is not completely dried, the ink does not adhere to the roller. Accordingly, there is an effect that the recording medium can be wound up while maintaining a high-quality image recording surface without the ink adhering to the roller being reattached to the recording medium.
Further, the amount of slack of the recording medium generated between the image recording apparatus and the recording medium winding device can be detected by a sensor, and an appropriate tension can be applied to the recording medium using the slack of the recording medium. . For this reason, the tension of the recording medium stretched between the take-up roller and the tension roller can be appropriately maintained regardless of the type of the recording medium, and the recording medium is wrinkled when the recording medium is taken up. This is advantageous in that it is possible to perform a highly accurate winding operation.

For this reason, there is an effect that the recording medium can be wound up while maintaining a high-quality image recording surface without the ink adhering to the roller reattaching to the recording medium.

  Further, since the number of rollers can be reduced, it is possible to perform a highly accurate winding operation while simplifying the device configuration and reducing the size of the device.

  According to the third aspect of the present invention, since the rotational torque of the tension roller can be adjusted, a recording medium that does not cause a problem even if it is wound tightly is wound tightly while applying a strong tension and then wound up. The size of the roll of the recording medium is reduced depending on the nature of the recording medium, such as loosely winding it with a low tension for recording media that may damage the fabric when tightly wound. Can be adjusted. For this reason, it is possible to perform a winding operation with various tensions on various recording media.

According to the fourth aspect of the present invention, when the recording medium on which the image is recorded is a fabric, the winding can be performed by applying an appropriate tension according to the weight of the fabric. The recording medium can be wound while maintaining the image recording surface.

According to the fifth aspect of the invention, since the auxiliary material roller is provided above the take-up roller, the auxiliary material can be easily replaced and replenished while the recording medium is being taken up sequentially. When the image recording is performed by the image recording apparatus, even when the auxiliary material runs out during the image recording operation, the auxiliary material can be easily replaced and replenished without interrupting the image recording operation. For this reason, it is possible to prevent the winding operation from being performed with the auxiliary material being cut off, and it is possible to perform the winding operation of the recording medium with high accuracy and efficiency.

  Hereinafter, an embodiment of a recording medium winding device according to the present invention will be described with reference to the drawings.

  First, as shown in FIG. 1, the recording medium winding device 1 in the present embodiment performs image recording after image recording is performed by the image recording device 2 that performs image recording on the recording medium P as the recording medium P. Is a device for winding the recording medium P on which is recorded. The image recording apparatus 2 is, for example, an inkjet type image recording apparatus 2 that records an image by ejecting ink onto the recording medium P based on predetermined image information. Image recording. Note that the image recording apparatus 2 is not limited to the ink jet type, and any apparatus capable of recording an image on a long recording medium P may be used. The image recording apparatus 2 is provided with a discharge port 3 that extends in the longitudinal direction of the image recording apparatus 2 and discharges the recording medium P on which image recording has been performed. The recording medium winding apparatus 1 is an image recording apparatus. 2 on the downstream side in the conveyance direction X of the recording medium P sent out from the two outlets 3.

  The recording medium winding device 1 is disposed in the vicinity of the discharge port 3 of the image recording device 2, and includes a device support base 4 having a width dimension longer than that of the discharge port 3 of the image recording device 2. The apparatus support 4 is fixed to the wheel 5 for moving the recording medium winding device 1 and the floor surface during the winding operation so that the recording medium winding device 1 is fixed and is moved away from the floor surface during the movement. A free leg 6 is attached.

  A pair of device side walls 7 and 7 are attached to both ends in the width direction of the device support 4 so as to be substantially perpendicular to the device support 4.

  On the side of each apparatus side wall 7, 7 that is away from the image recording apparatus 2, at a substantially central part in the vertical direction, first cutout parts 8, 8 from the downstream side to the upstream side in the feeding direction of the recording medium P. Is formed. A bearing (not shown) is provided in the first notches 8, 8, and a rotating shaft 10 of the take-up roller 9 is rotatably supported by the bearing. A roller driving motor 20 as a roller driving mechanism is connected to one end of the rotating shaft 10 of the winding roller 9, and the winding roller 9 is driven to rotate when the roller driving motor 20 is driven. An end portion of the recording medium P discharged from the image recording apparatus 2 is locked by a winding roller 9, and the recording medium P can be wound when the winding roller 9 is driven to rotate.

  Further, second cutout portions 11 and 11 are formed above the first cutout portions 8 and 8 of the apparatus side walls 7 and 7 by being cut out substantially vertically from the upper direction to the lower direction shown in FIG. Has been. A bearing (not shown) is provided in each of the second notches 11 and 11 of the apparatus side walls 7 and 7, and an auxiliary material H that is taken up together with the recording medium P when the recording medium P is taken up is provided on the bearing. A rotating shaft 13 of the wound auxiliary material roller 12 is rotatably supported. The auxiliary material H is provided between the recording media P in order to prevent the image recording surface of the recording medium P taken up by the take-up roller 9 from being damaged by contacting the non-image recording surface of the recording medium P. Is sandwiched between them so that they do not come into direct contact. The auxiliary material H is in the form of a sheet such as a slip sheet, for example, and has substantially the same width as the recording medium P.

  Further, a tension that is held on the upper side of the apparatus side walls 7 and 7 on the upstream side of the auxiliary material roller 12 in the recording medium transport direction X from the non-recording surface side with the recording medium P while applying a certain tension. A roller 14 is rotatably provided.

  The surface of the tension roller 14 is formed of a highly adhesive material such as resin, and a certain tension is applied to the recording medium P by generating a frictional force between the recording medium P and the tension roller 14. ing. The tension roller 14 only needs to be in a state where the surface thereof generates a frictional force with the recording medium P, and the entire tension roller 14 may be formed of an adhesive material. The roller 14 itself may be formed of metal, and the surface thereof may be covered with an adhesive material. Here, as the material having adhesiveness, for example, a non-slip belt (manufactured by Mochida Shoko Co., Ltd.) or a material having adhesiveness equivalent to this can be used. The adhesive material is not limited to this, and any material that generates a frictional force between the recording medium P and the tension roller 14 can be used.

  A torque adjusting mechanism 21 (see FIG. 2) for adjusting the rotational torque of the tension roller 14 is provided at one end of the rotary shaft 15 of the tension roller 14. The torque adjusting mechanism 21 includes, for example, a friction plate (not shown) attached to the rotary shaft 15 and a side plate (not shown) fixed to the rotary shaft 15 and disposed between the friction plate and the tension roller 14. And the rotational torque of the tension roller 14 can be adjusted by moving the friction plate toward and away from the side plate. That is, if the friction plate is strongly pressed against the side plate, a large load is applied to the rotation of the rotary shaft 15, and the tension roller 14 does not rotate unless a large force is applied. Conversely, if the pressing force is weakened, the load on the rotating shaft 15 is reduced, and the tension roller 14 rotates even with a small force. Therefore, when it is desired to apply a large tension to the recording medium P stretched between the tension roller 14 and the take-up roller 9, the friction plate is strongly pressed against the side plate to increase the rotational torque, and the recording medium When it is desired to reduce the tension applied to P, the pressure on the side plate is released to reduce the rotational torque. The torque adjusting mechanism 21 may be any mechanism that can adjust the rotational torque of the rotating shaft 15 of the tension roller 14, and the configuration is not limited to that exemplified in the present embodiment.

  The recording medium P discharged from the discharge port 3 of the image recording apparatus 2 is held by the tension roller 14 and conveyed toward the winding roller 9, but after being discharged from the discharge port 3, the recording medium P is wound by the winding device. Until it is started, it hangs down by its own weight between the image recording apparatus 2 and the recording medium winding apparatus 1, and the recording medium P is placed between the image recording apparatus 2 and the tension roller 14 of the recording medium winding apparatus 1. It is designed to cause slack. A slack detection sensor 16 is provided as a sensor for detecting the slack amount of the recording medium P at one side end of each device side wall 7, 7 facing the image recording device 2. The slack detection sensor 16 is, for example, an optical sensor including a light emitter that includes a light emitting element that emits light such as infrared light and a light receiver that includes a light receiving element that senses light emitted from the light emitter. A light emitter is provided on the device side walls 7 and 7, a light receiver is provided on the other device side walls 7 and 7, and a light emitting surface (not shown) of the light emitter and a light receiving surface (not shown) of the light receiver are opposed to each other. It has been. The light receiver receives the light emitted from the light emitter, but emits light when the recording medium P discharged from the image recording apparatus 2 gradually hangs down by its own weight and passes between the light emitter and the light receiver. The light irradiated from the receiver is blocked by the recording medium P and is not received by the receiver. Since the amount of slack of the recording medium P formed between the image recording apparatus 2 and the recording medium winding apparatus 1 increases as the recording medium P droops more, the slack position of the recording medium P is detected by the slack detection sensor 16. By detecting, the amount of slack of the recording medium P can be grasped. As a result, it is possible to detect that the recording medium P hangs down to a predetermined position and an amount of slack suitable for applying tension to the recording medium P is formed.

  The apparatus side walls 7 are provided with guide rails (not shown) along the vertical direction shown in FIG. The slack detection sensor 16 is guided, for example, from the position a to the position b shown in FIG. 1 by the sensor moving mechanism 19 (see FIG. 2) while keeping the height of the light emitter and the light receiver substantially the same. It can move up and down along the rail.

  Next, a control configuration of the recording medium winding device 1 according to the present embodiment will be described with reference to FIG.

  The image recording apparatus 2 includes an input unit 17 through which a user inputs the type of the recording medium P, the degree of winding of the recording medium P, and the like, and information input from the input unit 17 or an external terminal device (not shown). Is sent to the control unit 18. The input unit 17 is, for example, a keyboard or an operation panel, and the user can select the type or the like of the recording medium P by selecting an operation button or the like.

  The control unit 18 stores an optimum tension for each type of the recording medium P and a slack amount to be secured to obtain the tension. When the type of the recording medium P is input from the input unit 17 or the like. The controller 18 determines how much tension should be applied to the input recording medium P, and how much slack should be secured in consideration of the weight of the recording medium P. It is determined whether an appropriate tension can be applied to the recording medium P. That is, if an appropriate tension is not applied to the recording medium P, wrinkles and wrinkles will occur when the recording medium P is wound. On the other hand, if the tension applied to the recording medium P is too strong, the recording medium P may be stretched and the image recorded on the surface may be distorted, or the recording medium P itself may be damaged. Further, even when it is desired to obtain the same tension, for example, in the case of a heavy recording medium P, a sufficient tension can be applied with a small amount of slack, whereas in the case of a light recording medium P, it is slack. If the amount is not increased, sufficient tension cannot be applied. For this reason, the control unit 18 can adjust the slack amount of the recording medium based on information input from the input unit or the like, and can thereby maintain an optimum tension for each recording medium.

  The control unit 18 controls the sensor moving mechanism 19 based on information input from the input unit 17 and adjusts the position of the slack detection sensor 16. That is, the slack detection sensor 16 detects the position of the recording medium P when the recording medium P that is discharged from the discharge port 3 of the image recording apparatus 2 and hangs down passes between the slack detection sensors 16. The slack detecting sensor 16 is moved to a position where the recording medium P can be detected when the recording medium P passes through a position where the slack amount is necessary to secure an appropriate tension. Therefore, for example, when a small amount of slack is sufficient to secure an appropriate tension, the control unit 18 moves the slack detection sensor 16 to the position a shown in FIG. 1 to detect the recording medium P with a small amount of slack. It comes to be able to do it. Further, when a large amount of slack is required to secure an appropriate tension, the control unit 18 positions the slack detection sensor 16 at the position b shown in FIG. 1 so that the recording medium P with a large amount of slack can be detected. It is supposed to be moved to.

  An electrical signal is sent from the slack detection sensor 16 to the control unit 18, and the recording medium P discharged from the image recording apparatus 2 is dropped in order, and the image recording apparatus 2, the recording medium winding apparatus 1, and the like. When the slack detection sensor 16 detects the sagging recording medium P, the control unit 18 sags the recording medium P to a predetermined slack position, and the amount of slack necessary for applying tension. Is determined to be secured. The control unit 18 controls the roller drive motor 20 to drive the take-up roller 9 to take up the recording medium P.

  Further, the control unit 18 controls the torque adjusting mechanism 21 according to the degree of winding of the recording medium P input from the input unit 17 to adjust the pressing force of the friction plate that presses against the side plate, and the tension roller 14. It is designed to adjust the rotation torque. That is, when the recording medium P is tightly wound to be finished into one roller, the rotational torque of the tension roller 14 is increased so that the recording medium P is tightly stretched between the take-up roller 9 and the tension roller 14. In order to finish the recording medium P so as to be loosely wound, the tension applied to the recording medium P stretched between the take-up roller 9 and the tension roller 14 is increased by reducing the rotational torque of the tension roller 14. Try not to overdo it.

  Next, the operation of the recording medium winding device 1 in this embodiment will be described.

  When the winding condition of the recording medium P such as the type of the recording medium P is input from the input unit 17, the control unit 18 is slacked to a position where the slack amount required according to the type of the recording medium P can be detected. The detection sensor 16 is moved. That is, for example, when a small amount of slack is sufficient, the slack detection sensor 16 is moved to the position a shown in FIG. 1, and when a large amount of slack is required, the slack detection sensor 16 is shown in FIG. Move to the position b shown. When image recording is performed by the image recording apparatus 2, the recording medium P is discharged from the discharge port 3, and hangs down by its own weight between the image recording apparatus 2 and the recording medium winding apparatus 1 without being wound for a while. Causes slack. When the recording medium P hangs down to a predetermined slack position and is detected by the slack detection sensor 16, the control unit 18 drives the roller drive motor 20 to rotate the winding roller 9 and starts winding the recording medium P. To do. At this time, the end portion of the auxiliary material H wound around the auxiliary material roller 12 positioned above the winding roller 9 is in contact with the image recording surface of the recording medium P, and the auxiliary material is sequentially rotated as the winding roller 9 rotates. The auxiliary material H is fed out from the roller 12, and the auxiliary material H is wound together with the recording medium P, and is wound up by the winding roller 9 in a state where the recording medium P and the auxiliary material H are overlapped. At the same time, the control unit 18 adjusts the rotational torque applied to the tension roller 14 by controlling the torque adjusting mechanism 21 of the tension roller 14 in accordance with the winding condition input from the input unit 17. Control is performed so that the tension of the recording medium P stretched between the tension roller 14 is suitable for the winding condition. When all of the auxiliary material H wound around the auxiliary material roller 12 is taken up by the take-up roller 9, the user stops the winding device and forms the auxiliary material roller 12 in the second cutout portions 11 and 11. The new auxiliary material roller 12 is set by removing from the bearing. During this time, the recording medium P sequentially discharged from the image recording apparatus 2 hangs between the image recording apparatus 2 and the recording medium winding apparatus 1 and becomes slack. When the winding operation is resumed, the control unit 18 controls the roller drive motor 20 to rotationally drive the winding roller 9 so that the recording medium P has a predetermined slack amount. The winding operation of the recording medium P is performed so that becomes constant. Thereby, the auxiliary material roller 12 can be replaced and the winding operation can be continued without interrupting the image recording operation of the image recording apparatus 2.

  According to the present embodiment, since the tension roller 14 is formed of an adhesive material, the recording medium P can be recorded by the single tension roller 14 without sandwiching the recording medium P discharged from the image recording apparatus 2 with a pair of rollers. It can be supported only from the non-image recording surface side. Therefore, even if the recording medium P is discharged immediately after image recording, the ink does not adhere to the roller, and the ink attached to the roller does not adhere again to the recording medium P, thereby forming a high-quality image. can do.

  Further, the amount of slack of the recording medium P generated between the image recording apparatus 2 and the recording medium winding apparatus 1 is detected by the slack detection sensor 16, and the slackness of the recording medium P is used to appropriately apply to the recording medium P. Therefore, it is possible to prevent the recording medium P from being wrinkled when the recording medium P is wound up.

  Further, since the recording medium P can be wound while the auxiliary material H is applied to the image recording surface of the recording medium P, it is possible to prevent the image recording surface from being scratched and to wind the auxiliary material roller 12. Since the roller 9 is positioned above, the recording medium P can be easily replaced even when the auxiliary material H runs out while the recording medium P is being wound up, and it is not necessary to interrupt the operation. The taking operation can be performed efficiently.

  In this embodiment, the slack detection sensor 16 that detects the slack amount of the recording medium P can be stopped steplessly. For example, in the case of a heavy recording medium P on the guide rail, a light recording medium is used. In the case of P, a plurality of sensor stop positions corresponding to the type of the recording medium P are provided, and the type of the recording medium P is selectively input from the input unit 17, and the slack detection sensor 16 is placed at the corresponding position. You may make it move.

  Further, the position where the slack detection sensor 16 is installed is not limited to that shown in the present embodiment, and may be a position where the slack amount of the recording medium P can be detected.

  Furthermore, in this embodiment, the slack detection sensor 16 is an optical sensor that detects the position of the recording medium P. However, the type of the sensor is not limited to this, and for example, the weight of the recording medium P in the portion where the slack is generated It may be detected by measuring whether the amount of slack is optimal for obtaining the necessary tension.

  Further, in the present embodiment, the sheet-like slip sheet is exemplified as the auxiliary material H. However, as the auxiliary material H, in addition to paper, films such as polystyrene and polyester, and other wound recording media P can be used. It is possible to apply a material that is easily peeled off from the recording medium P when it is warped and does not affect the image recording surface of the recording medium P.

  Further, as the recording medium P, recording paper P made of various materials such as various papers such as plain paper, recycled paper, glossy paper, various fabrics, various non-woven fabrics, resin, metal, and glass can be applied.

  In addition, it is needless to say that the present invention is not limited to the above embodiment and can be modified as appropriate.
