Description

[Technical Field]

[0001] The present invention relates to a retaining member. [Background technology]

[0002] Conventionally, conveying devices for conveying sheet-like processed media are provided with rotating rollers for conveying the processed media. Among these rollers, some are known to have a high-friction layer formed on the outer surface of the roller to prevent misfeeding and improve conveying performance. For example, Patent Document 1 discloses a conveying roller in which a high-friction layer is formed on the outer circumferential surface of the roller body to apply a conveying force to the recording medium. The high-friction layer described in Patent Document 1 is fixed to the circumferential surface of the conveying roller with a sharp, exposed portion. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-121686 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when the processed medium is held and transported by a holding member made of, for example, a relatively hard and resistant resin material, the sharp part of the high-friction layer is unlikely to pierce the surface of the holding member (the object to be transported), and especially when the holding member (the object to be transported) is unused or in an early stage of use, the gripping force during transport is insufficient, which can cause transport errors.

[0005] The present invention has been made to solve these problems, and provides a holding member that can reliably transport a medium to be processed. [Means for solving the problem]

[0006] In order to solve the above problem, the holding member of the present invention is a holding member in which a processed medium is placed in a first area of ​​a substrate, and a second area outside the first area is transported by being clamped between a drive roller and a driven roller that rotates in accordance with the rotation of the drive roller, and at least the drive roller of the drive roller or the driven roller has protrusions arranged on its peripheral surface, and the surface of the substrate with which the roller having the protrusions contacts is provided with a transport processing portion that is processed to make it easy for the protrusions to bite into when it comes into contact, at least in the range corresponding to the second area. [Effects of the Invention]

[0007] According to the present invention, the medium to be processed can be transported reliably. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] 1 to 11, an embodiment of a holding member 1 according to the present invention will be described. The holding member 1 is conveyed by being sandwiched between a pair of rollers in an apparatus equipped with a conveying unit 110 including a pair of rollers. As described below, the pair of rollers is a drive roller 103 and a driven roller 104 that rotates in conjunction with the rotation of the drive roller 103. In addition to the pair of rollers, the conveying unit 110 also includes a roller drive unit (motor, not shown) that drives the drive roller 103. A medium to be cut is placed on one side of the holding member 1, and the holding member 1 is conveyed by the conveying unit 110 of the apparatus while holding the medium. In FIGS. 1 to 3, the side of the holding member 1 on which the medium to be cut is placed (one side) is referred to as the "front side 11," and the other side is referred to as the "rear side 21." In the following embodiment, an example will be described in which the apparatus to which the holding member 1 is applied is a cutting apparatus 100, and the holding member 1 holds a medium to be cut M as the medium to be cut. That is, in the embodiment, the holding member 1 is used for conveyance in a cutting device 100 (cutting machine) for cutting the medium M to be cut. The cutting device 100 in the embodiment is assumed to be a device that cuts out the medium M to be cut while conveying it placed on the holding member 1. In FIG. 1 and other figures, the width direction of the holding member 1 is referred to as the "width direction W," and the length direction of the holding member 1 is referred to as the "length direction L." In the embodiment, the width direction W of the holding member 1 coincides with the movement direction (main scanning direction X) of the cutting unit 101 of the cutting device 100, which will be described later. Furthermore, the length direction L of the holding member 1 coincides with the conveyance direction Y of the holding member 1 by the conveyance unit 110 (see FIG. 8 and other figures).

[0010] As shown in FIGS. 1 to 7 , the holding member 1 according to the embodiment includes a substrate 10 that is substantially rectangular in plan view and holds a medium M to be cut on the surface 11 side of the substrate 10. The substrate 10 is formed of a highly hard resin, such as polycarbonate. Note that the substrate 10 may be formed of any material that is resistant to deformation and has excellent durability, and the material for the substrate 10 is not limited to polycarbonate. As shown in FIGS. 1 , 2 , 4 , and 5 , a first region Ar1 is defined at approximately the center of the width direction W on the surface 11 side of the substrate 10, and the medium M to be cut is placed in the first region Ar1. As shown in FIG. 1 , a placement frame 12 is preferably provided in the first region Ar1 by printing or the like to serve as a guide for placing the medium M. Furthermore, as shown in FIGS. 1 and 2 , a guide indicator 13 indicating the position of the square of the placement frame 12 is preferably provided on the surface 11 side of the substrate 10 by printing or the like. As shown in Figures 4 and 5, a temporary fixing portion 14 configured by adhering double-sided tape or the like is provided within the arrangement frame 12 of the first area Ar1. When the holding member 1 is unused, as shown in Figure 4, the surface of the temporary fixing portion 14 is covered with a protective film 15 to protect it from dust and the like. When in use, the protective film 15 is peeled off, and the medium M to be cut is held in a temporarily fixed state on the temporary fixing portion 14 (see Figure 9). Note that the method for placing the medium M to be cut on the holding member 1 is not limited to this, and various methods can be applied. It is sufficient that the medium M to be cut does not shift during the cutting operation. For example, an adhesive layer such as glue may be printed or applied within the arrangement frame 12 of the first area Ar1 to form the temporary fixing portion 14.

[0011] In the illustrated example, the area of ​​the substrate 10 outside the first area Ar1 (the area where the medium to be cut M is placed) is designated as the second area Ar2. As shown in Figures 3, 4, 6, etc., in the embodiment, the second area Ar2 is on both sides of the first area Ar1 in the width direction W of the substrate 10. The holding member 1 is transported by the second area Ar2 being sandwiched between a pair of rollers (a drive roller 103 and a driven roller 104). A transport processed section 3 is provided on the surface of the substrate 10 that comes into contact with a roller having protrusions 51 (see Figures 10 and 11), which will be described later, in at least an area corresponding to the second area Ar2. The processed section 3 is processed so that the protrusions 51 can easily bite into the surface when the protrusions 51 come into contact with the surface. In this embodiment, the roller having the protrusions 51 on its peripheral surface is a drive roller 103 that contacts the back surface 21 of the substrate 10, and the conveying processing section 3 is provided in the second region Ar2 on the back surface 21 of the substrate 10, which is the portion that is clamped between a pair of rollers, i.e., the side end portion along the conveying direction Y of the substrate 10.

[0012] As shown in FIG. 7, for example, the processed portion 3 for conveyance has a certain thickness and a certain degree of deformability and flexibility, allowing it to accept the protrusions 51 when they contact it. That is, at least the contact surface side of the processed portion 3 for conveyance is deformable to match the shape of the protrusions 51 so that a large contact area is formed between the processed portion 3 for conveyance and the protrusions 51 when pressed against it. The processed portion 3 for conveyance is formed of a high-friction material so as to increase frictional resistance when it contacts the drive roller 103 having the protrusions 51 on its circumferential surface. The processed portion 3 for conveyance is not particularly limited in terms of the specific material for the processed portion 3 or the method for providing the processed portion 3, as long as it is formed of a high-friction material and has flexibility to accept the protrusions 51. The processed portion 3 for conveyance may be formed by adhering a film made of a polyester material, such as cellophane tape, via an adhesive layer (sticky layer). The processed portion 3 for conveyance may also be a printed layer or a painted layer formed to a certain thickness (e.g., approximately 20 microns). The ink used for printing or painting may be a general ink containing a resin or the like. In this case, it is preferable to apply a plurality of layers to increase the thickness. The ink may be a rubber-based ink (paint) such as a urethane paint.

[0013] 8 to 11, the relationship between the holding member 1 and a cutting device 100 that cuts a medium M held by the holding member 1 will be described. As shown in FIG. 8, the cutting device 100 includes a cutting unit 101 and a conveying section 110. In this embodiment, the cutting unit 101 is an operating unit that cuts the medium M placed on the holding member 1. During cutting, the cutting unit 101 is movable in a movement direction (main scanning direction X) by a drive section (motor) not shown. The conveying section 110 conveys the holding member 1, on whose surface 11 the medium M is placed, in a conveying direction Y that intersects (substantially perpendicular to) the movement direction of the cutting unit 101 (main scanning direction X). In this way, in the cutting device 100, the cutting unit 101 moves appropriately in the main scanning direction X, and the medium M is conveyed in the conveying direction Y that is substantially perpendicular to the main scanning direction X. This allows the cutting unit 101 and the medium M to move freely relative to each other on the XY plane, allowing the cutting unit 101 to cut the medium M. Note that a general configuration can be applied to the cutting unit 101, and detailed description thereof will be omitted here.

[0014] The transport unit 110 includes a pair of rollers, and as shown in FIG. 9 , the pair of rollers sandwich the holding member 1, which holds the medium M to be cut, from the front and back, and transports the medium M placed on the holding member 1 in the transport direction Y so that the medium M passes below the cutting unit 101. As described above, in the embodiment, the pair of rollers is the drive roller 103 and the driven roller 104 that rotates as the drive roller 103 rotates. The drive roller 103 is provided on the back surface 21 side of the holding member 1 and extends in the main scanning direction X (the width direction W of the holding member 1). The driven roller 104 is located on the front surface 11 side of the holding member 1, facing the drive roller 103 with the holding member 1 in between. In the embodiment, a roller shaft 105 that is approximately parallel to the drive roller 103 is provided on the front surface 11 side of the holding member 1 and extends in the main scanning direction X. The driven rollers 104 are provided on both ends of the roller shaft 105 in the main scanning direction X, with a width corresponding to the second area Ar2 of the holding member 1 (see FIG. 9). In this way, the driven rollers 104 are provided on the surface 11 side of the holding member 1, but because they are arranged corresponding to the second area Ar2, they do not interfere with the medium M placed on the surface 11 side. The driven rollers 104 are made of a resin with excellent sliding properties, such as POM. However, the material from which the driven rollers 104 are made is not limited to this.

[0015] The drive roller 103 is made of a metal such as stainless steel. As shown in FIG. 9 and other figures, high-friction processed portions 5 are formed on the circumferential surface of the drive roller 103 in a range corresponding to the second region Ar2 at both ends in the main scanning direction X. As shown in FIGS. 10 and 11, the high-friction processed portions 5 have multiple protrusions 51. The protrusions 51 provided on the high-friction processed portions 5 are preferably formed at a constant pitch. While the specific arrangement and shape of the protrusions 51 are not particularly limited, it is preferable that the protrusions 51 have a shape that exerts a high frictional force when they come into contact with the conveying processed portion 3 of the holding member 1. For example, in the illustrated example, the apex of the protrusions 51 facing outward from the circumferential surface of the drive roller 103 is sharply pointed. It is preferable that the shape, orientation, angle, etc. of each protrusion 51 are regularly aligned. That is, the shape, orientation, angle, etc. of each protrusion 51 may all be the same, or they may be arranged in a regular pattern, for example, with triangular protrusions 51 having an inclined surface on the right side and triangular protrusions 51 having an inclined surface on the left side alternately in a cross-sectional view. The protrusions 51 may have any shape that improves the grip of the holding member 1 by the roller pair, and for example, the protrusions 51 may form unevenness on the circumferential surface of the roller, be arranged at regular intervals, and have acute angles at their apexes. Note that the specific shape, etc. of the protrusions 51 are not limited to the examples shown in the figures and described herein.

[0016] Next, the operation of the holding member 1 according to this embodiment will be described. First, a conveying processed section 3 is formed on the back surface 21 of the holding member 1, at least on the front surface 11, in a region corresponding to the region (second region Ar2) where the medium M is not placed. The conveying processed section 3 may be formed by adhering cellophane tape, or by printing or painting. When setting the holding member 1 in the cutting device 100, the protective film 15 on the front surface 11 of the holding member 1 is peeled off, and the medium M is temporarily fixed and held on the temporary fixing section 14 in the first region Ar1. Then, the holding member 1 is placed in the conveying section 110 of the cutting device 100 so that the driven rollers 104 are positioned in the second region Ar2, which are on both sides of the first region Ar1, so as to sandwich the medium M from both sides. As a result, the holding member 1 is set in the conveying section 110 of the cutting device 100 with the second region Ar2 sandwiched from the front and back by the drive roller 103 and the driven roller 104.

[0017] When the cutting operation begins, the cutting unit 101 moves in the main scanning direction X (the width direction W of the holding member 1), and the pair of rollers (drive roller 103 and driven roller 104) of the conveying section 110 sandwich the holding member 1 from the front and back, conveying the holding member 1 along the conveying direction Y (the length direction L of the holding member 1). At this time, the protrusions 51 of the high-friction processed sections 5 provided on both ends of the drive roller 103 arranged on the back surface 21 of the holding member 1 in the main scanning direction X (the width direction W of the holding member 1) come into contact with the conveying processed section 3 provided on the back surface 21 of the holding member 1. The driven roller 104 contacts the second region Ar2 of the holding member 1 from the front surface 11 side, pressing it toward the back surface 21 side. As a result, the protrusions 51 of the drive roller 103 are pressed against the conveying processed section 3, and at least the contact surface side of the conveying processed section 3 changes shape to match the shape of the protrusions 51. Therefore, when the protrusions 51 are pressed against the conveying processing unit 3, the contact surface between the protrusions 51 and the conveying processing unit 3 is large, resulting in increased frictional resistance. When viewed in cross section, for example, as shown in FIG. 11 , the sharply pointed tops of the protrusions 51 pierce the conveying processing unit 3, and the drive roller 103 rotates while the protrusions 51 bite into the contact surface of the conveying processing unit 3. As a result, the holding member 1 is conveyed in the conveying direction Y as if pushed out by the drive roller 103. In this embodiment, the protrusions 51 are formed at a substantially constant pitch. Therefore, even when the drive roller 103 rotates in the reverse direction during a cutting operation to convey the holding member 1 in the reverse direction along the conveying direction Y (the reverse direction Yb shown in FIG. 8), the holding member 1 can be conveyed stably, similar to when the holding member 1 is conveyed in the forward direction (the forward direction Ya shown in FIG. 8), and conveying errors such as slipping or shifting of the holding member 1 are prevented.

[0018] In this manner, in the embodiment, the drive roller 103 rotates while the protrusions 51 bite into the conveying processed portion 3 of the holding member 1. This allows the medium M held (placed) on the holding member 1 to be conveyed while a strong gripping force acts on the holding member 1.

[0019] As described above, the holding member 1 according to this embodiment is a holding member 1 in which a medium to be cut (M) is placed in the first region Ar1 of the substrate 10, and the second region Ar2 outside the first region Ar1 is sandwiched between the drive roller 103 and the driven roller 104 that rotates with the rotation of the drive roller 103 to be transported. The drive roller 103 has protrusions 51 arranged on at least a portion of its circumferential surface. The surface of the substrate 10 that the drive roller 103 contacts, at least in the area corresponding to the second region Ar2, is provided with a transport-use processed portion 3 that is processed to allow the protrusions 51 to easily dig into the surface upon contact. In this way, when the protrusions 51 are provided on the circumferential surface of the drive roller 103, processing the surface that the protrusions 51 contact to allow the protrusions 51 to easily dig into increases the gripping force, preventing the holding member 1 from slipping on the roller surface during transport. This prevents misalignment during transport, improves transport performance, and ensures stable and reliable transport of the medium to be cut (M). By increasing the gripping force in this way, even if the medium to be cut M (medium to be processed) placed and held on the holding member 1 is a hard or thick paper such as Kent paper, transport errors do not occur and high transport accuracy can be achieved.

[0020] As described above, the protrusions 51 in this embodiment are provided on the circumferential surface of the drive roller 103 in a range corresponding to the second region Ar2. In this embodiment, the transport processing section 3 is provided in at least a range corresponding to the second region Ar2. Even if the protrusions 51 are provided in a range other than the range corresponding to the transport processing section 3, no gripping effect can be expected. Furthermore, the medium to be processed, i.e., the medium to be cut M, is placed in the first region Ar1. Therefore, if the protrusions 51 are provided in a range corresponding to the first region Ar1, there is a risk that the protrusions 51 will affect the medium to be processed. In this regard, in this embodiment, the gripping force of the holding member 1 during transport can be effectively improved, thereby increasing transport accuracy.

[0021] In addition, in this embodiment, the conveying processing section 3 is provided at the side edge of the substrate 10 along the conveying direction Y. The holding member 1 is conveyed by the conveying section 110 along the conveying direction Y. However, since the medium to be cut (M) is placed in the first region Ar1, which is the center of the width direction W, if this region is pinched by the rollers of the conveying section 110, the cutting operation will be affected. For this reason, as shown in FIG. 9, the conveying section 110 conveys the medium by pinching the side edge along the conveying direction Y with a pair of rollers. To improve the gripping force and conveying accuracy of the conveying processing section 3, where the protrusions 51 are likely to dig in, it is necessary to press the portion where the protrusions 51 and the conveying processing section 3 face each other with a pair of rollers. Therefore, even if the conveying processing section 3 is provided in the first region Ar1, where it is difficult to arrange a pair of rollers, no effect can be expected. Instead, the conveying force can be strengthened by providing the conveying processing section 3 in the second region Ar2, where the medium can be pressed by a pair of rollers.

[0022] Furthermore, the conveying processed portion 3 of the embodiment is formed of a high-friction material, which generates high friction resistance between the roller (drive roller 103) on which the protrusions 51 are provided, and the holding member 1 can be reliably conveyed by the roller pair.

[0023] Furthermore, the transport processed part 3 of the embodiment may be configured so that at least the contact surface side can change shape to match the shape of the protrusion 51 so that a large contact surface comes into contact with the protrusion 51 when the protrusion 51 is pressed against it. This increases the frictional resistance generated between the roller (drive roller 103) on which the protrusion 51 is provided, thereby strengthening the transport force.

[0024] Furthermore, the protrusions 51 in the embodiment are formed at a constant pitch. It is assumed that the conveyance unit 110 conveys the holding member 1 (the medium M to be cut placed on the holding member) back and forth along the conveyance direction Y. In this case as well, a constant pitch allows for stable conveyance.

[0025] Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present invention. For example, as shown in FIG. 12, recesses 31 capable of receiving the protrusions 51 may be formed on the surface of the conveying processed portion 3a of the holding member 1a that comes into contact with the protrusions 51. In this case, the recesses 31 are preferably formed at approximately the same pitch as the protrusions 51. The recesses 31 are also preferably shaped to fit into the protrusions 51. When such recesses 31 are formed in the conveying processed portion 3a, the protrusions 51 and the recesses 31 fit and mesh together like gears, providing a stronger gripping force. This allows the holding member 1a on which the medium M is placed to be conveyed more stably, reliably, and accurately.

[0026] Furthermore, in the embodiment, a high-friction processed portion 5 having multiple protrusions 51 formed on the peripheral surface of the roller (drive roller 103 in this embodiment) of the conveying unit 110 is provided, and a conveying processed portion 3 having a processing that allows the protrusions 51 to easily dig into the roller when the roller contacts the roller is provided on the holding member 1 side. However, the arrangement of the high-friction processed portion with protrusions and the conveying processed portion that receives the protrusions is not limited to this. For example, as shown in FIG. 13 , a high-friction processed portion 3b having protrusions 32 arranged on the surface that contacts the roller (drive roller 106 in this embodiment) may be provided in a range corresponding to the second region Ar2 of the substrate 10 of the holding member 1b, and a conveying processed portion 107 having a processing that allows the protrusions 32 to easily dig into the roller (drive roller 106 in this embodiment) may be formed on the peripheral surface of the roller (drive roller 106 in this embodiment) of the conveying unit 110 in a range corresponding to the protrusions 32 (i.e., the portion that contacts the portion 3b). In this case, too, the holding member 1b can be conveyed in the conveying direction Y with a high grip force when the pair of rollers of the conveying unit 110 rotates.

[0027] Furthermore, in the embodiment, a case has been illustrated in which the conveying processed portion 3 is provided on the back surface 21 of the holding member 1, and the high-friction processed portion 5 is provided on the circumferential surface of the drive roller 103, which is one of the pair of rollers constituting the conveying unit 110 and is located on the back surface 21 of the holding member 1, but the arrangement of the conveying processed portion and the high-friction processed portion is not limited to this. The high-friction processed portion only needs to be provided on at least the drive roller 103 of the drive roller 103 or the driven roller 104, but, for example, a similar high-friction processed portion may also be provided on the circumferential surface of the driven roller 104. In this case, a conveying processed portion is also provided on the front surface 11 of the holding member 1. In this case, when the pair of rollers of the conveying unit 110 rotates, the holding member 1 sandwiched between the pair of rollers is held with a high grip force and conveyed in the conveying direction Y with high precision.

[0028] Furthermore, in the embodiment, the case where the processed portion 3 for conveyance is provided only on the side edge (second region Ar2) of the substrate 10 along the conveying direction Y is illustrated, but the area where the processed portion 3 for conveyance is provided is not limited to the second region Ar2. For example, when the processed portion 3 for conveyance is provided by printing, painting, or the like, the process is the same whether the processed portion 3 is provided only on the second region Ar2 or on the entire one surface (e.g., back surface 21) of the holding member 1. In such a case, the processed portion 3 for conveyance may be provided on the entire one surface (e.g., back surface 21) of the holding member 1. Note that even if the processed portion 3 for conveyance is provided on the entire one surface (e.g., back surface 21) of the holding member 1, a roller (e.g., driven roller 104) cannot be positioned so as to overlap the medium to be processed in the first region Ar1 where the medium is placed, and the roller pair does not face each other on the front and back of the holding member 1. In the area where the roller pair does not face each other, even if a high-friction processed portion 5 is provided, it will not be pressed against the processed portion 3 for conveyance, and therefore is meaningless in terms of strengthening the conveying force. For this reason, the high-friction processed portion 5 is provided only in the range corresponding to the second region Ar2 where the roller pair faces each other.

[0029] Furthermore, in the embodiment, the device in which the conveying unit 110 is provided is a cutting device 100 equipped with a cutting unit 101, and the workpiece medium placed and held on the holding member 1 is the medium to be cut by the cutting unit 101. However, the device in which the conveying unit 110 for conveying the holding member 1 is provided is not limited to a cutting device. The holding member 1 according to the embodiment can be widely applied to devices equipped with a conveying unit for conveying the holding member 1 on which the workpiece medium is placed. For example, the holding member may be a holding member conveyed by a conveying unit of a printing device equipped with a printing unit including a print head or the like. When the holding member is applied to a printing device, a print head is provided in the device instead of the cutting unit 101 described in the embodiment, and printing is performed by operating the print head while conveying the workpiece medium held on the holding member. Furthermore, the holding member can be applied to a wide range of devices, including not only printing devices that perform printing, but also drawing devices that perform drawing on the workpiece medium held on the holding member, various processing devices, and conveying devices in manufacturing sites.

[0030] In addition, in the embodiment, the second region Ar2 is on both sides of the first region Ar1 in the width direction W of the substrate 10, but the second region Ar2 is not limited to this. If the second region Ar2 is located in a position that does not interfere with the operation of an operating unit such as a cutting unit on the medium to be processed, it can be sandwiched between the roller pair of the conveying unit 110, and the second region Ar2 may be any portion that can be sandwiched between the roller pair.

[0031] In addition, the specific contents of the configuration, processing arrangement, order, and numerical values ​​shown in the above embodiment can be changed as appropriate without departing from the spirit of the present invention. Furthermore, the scope of the present invention is not limited to the above embodiment, but includes the scope of the invention described in the claims and its equivalents. [Explanation of symbols]
