The present invention relates to a roll support device.
Some printers for performing printing on long paper include a roll support device that supports a rolled medium such as roll paper obtained by winding long paper. This type of roll support device includes a pair of guide members that sandwich and regulate both end surfaces of a rolled medium as a support structure for supporting the rolled medium. In this type of roll support device, at the time of replacing the rolled medium, one guide member regulates one end surface of the rolled medium while the other guide member is attached to the other end surface of the rolled medium.
In the above-described roll support device, replacement of a rolled medium accompanies an operation of attaching/detaching a guide member to/from an end surface of the rolled medium. The operation of attaching/detaching the rolled medium is complicated. In addition, the guide member, which is detached at the time of detachment, may be lost.
According to an aspect of the embodiments, a roll support device disclosed in the present application includes: a shaft portion that supports a center hole of a rolled medium in which a medium is wound; a first guide member with which one end surface of the rolled medium in an axial direction of the shaft portion is in contact; a second guide member that is provided on the shaft portion and regulates, in the axial direction, an inner peripheral side of another end surface of the rolled medium in the axial direction; and a third guide member that regulates, in the axial direction, an outer peripheral side of the other end surface of the rolled medium supported by the shaft portion.
The object and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the claims.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention.
Embodiments of a roll support device disclosed in the present application will be described in detail below with reference to the drawings. Note that the following embodiments do not limit the roll support device disclosed in the present application.

The roll support device 1 of the present embodiment is used for supplying long paper to a printer that issues baggage tags and boarding passes, for example. The baggage tags are attached to baggage in an airport. The boarding passes record a flight number, a seat number, and the like of an aircraft of a passenger. Note that the roll support device 1 of the present embodiment is not limited to use of supporting roll paper for issuing the baggage tags and the boarding passes, and may be applied to support roll paper for creating tags such as various baggage tags and price tags, business forms, and the like.
The roll paper 5 is formed by winding long paper 5a around a core 5b. The long paper 5a has a so-called tape shape in which the roll paper 3 has a narrow dimension in the width direction (Y direction). In the present embodiment, for example, the roll paper 5, which has an outer diameter of approximately 200 [mm] or less and an outer diameter of the core 5b of approximately 80 mm, is used. Note that the roll paper is not limited to those having the core 5b. The roll paper without the core 5b may be used. Therefore, the center hole 5c of the roll paper 5 in the present embodiment refers to a through hole of the core 5b when the roll paper 5 has the core 5b, and refers to the center hole of the roll paper 5 itself when the roll paper 5 does not have the core 5b. Hereinafter, the center hole 5c of the roll paper 5 including the through hole of the core 5b of the roll paper 5 will be simply referred to as the center hole 5c of the roll paper 5.
Furthermore, although, the roll paper 5, in which the long paper 5a is wound around the core 5b, is used as the rolled medium in the present embodiment, the rolled medium is not limited to the roll paper 5. For example, label paper obtained by layering a label on release paper, and roll paper, in which a radio frequency identifier (RFID) tag, is embedded may be used as the rolled medium.

The second guide member 12 is detachably provided at an end opposite to the first guide member 11 in the axial direction X of the shaft portion 10. Furthermore, the second guide member 12 is provided so as to be attached in an orientation opposite to the axial direction X of the shaft portion 10. The second guide member 12 includes a fixed portion 12a, which is fixed at an end of the shaft portion 10, and a regulation portion 12b, which regulates the inner peripheral side of the right end surface 5R of the roll paper 5.
As illustrated in
As illustrated in
Furthermore, the regulation portion 12b is disposed such that the position of the regulation portion 12b in the axial direction X of the fixed portion 12a is closer to one end side in the axial direction X than the center in the axial direction X of the fixed portion 12a. Therefore, the position of the regulation portion 12b in the axial direction X of the shaft portion 10 can be switched in accordance with the width of the roll paper 5 to be used, by attaching the regulation portion 12b in an orientation opposite to the axial direction X of the shaft portion 10 (see
Furthermore, the upper end of the regulation portion 12b in the Z direction has an arc shape along the peripheral direction of the shaft portion 10, so that the regulation portion 12b can smoothly pass through the inner peripheral portion of the core 5b of the roll paper 5.
The third guide member 13 is disposed on the side of the right end surface 5R of the roll paper 5, supported by the shaft portion 10, and detachably provided on the base 14 below the second guide member 12. Furthermore, the third guide member 13 is provided so as to be attached in an orientation opposite to the axial direction X of the shaft portion 10. As illustrated in

As illustrated in
Furthermore, since the regulation portion 13b is disposed at an end of the fixed portion 13a in the axial direction X, the position of the regulation portion 13b in the axial direction X of the shaft portion 10 can be switched in accordance with the width of the roll paper 5 to be used, by attaching the regulation portion 13b in an orientation opposite to the axial direction X of the shaft portion 10.
(Range Regulated by Second Guide Member and Third Guide Member)
In the radial direction of the roll paper 5 supported by the shaft portion 10, the sum of a radial upper range A1 on the inner peripheral side of the right end surface 5R, regulated by the second guide member 12, and a radial lower range A2 on the outer peripheral side of the right end surface 5R, regulated by the third guide member 13, is equal to or larger than an entire range A3 from the inner periphery to the outer periphery of the right end surface 5R of the roll paper 5 (see
(Attachment of Roll Paper)
As illustrated in
When the roll paper 5 is attached to the roll support device 1, the shaft portion 10 and the second guide member 12 are passed through the center hole 5c of the roll paper 5, and then the left end surface 5L of the roll paper 5 is made to abut on the reference surface 11a of the first guide member 11. Subsequently, as illustrated in
When the center hole 5c of the roll paper 5 is supported by the shaft portion 10 as described above, the regulation surface 12c of the second guide member 12 is in contact with the inner peripheral side of the right end surface 5R of the roll paper 5 while the regulation surface 13c of the third guide member 13 is in contact with the outer peripheral side of the right end surface 5R of the roll paper 5. Therefore, the left end surface 5L of the roll paper 5 whose center hole 5c is supported by the shaft portion 10 is regulated by the reference surface 11a of the first guide member 11 over the radial direction in the axial direction X. The roll paper 5 is regulated by the regulation surface 12c of the second guide member 12 and the regulation surface 13c of the third guide member 13 from the inner periphery to the outer periphery of the right end surface 5R in the axial direction X.
The second guide member 12 and the third guide member 13 are attached to the shaft portion 10 of the roll paper 5 in a state of being preliminarily fixed at appropriate positions in the axial direction X of the shaft portion 10 in accordance with the roll paper 5 to be used. The second guide member 12 and the third guide member 13 may be adjusted to appropriate positions in the axial direction X and fixed after the roll paper 5 is supported by the shaft portion 10.
Note that, in one example in
Specifically, the guide roller 18 is disposed at a predetermined position to the shaft portion 10 such that an angle, formed by the feeding direction of the long paper 5a to a straight line connecting the center of the shaft portion 10 with the center of guide roller 18, in the case where the long paper 5a is drawn out from the upper portion of the roll paper 5, is equal to that in the case where the long paper 5a is drawn out from the lower portion of the roll paper 5, in a cross section orthogonal to the axial direction of the shaft portion 10 and the guide roller 18. This equalizes the states where the long paper 5a is sent from the roll paper 5 to the printer via the guide roller 18, and can inhibit a change in the printing state of the long paper 5a to stabilize printing quality.
Furthermore, the roll support device 1 of the first embodiment includes a plurality of types of second guide members 12A and 12B, which serve as the second guide members 12, having different positions of the regulation portions 12b in the axial direction X of the fixed portion 12a (see
Similarly to the plurality of types of second guide members 12A and 12B, although not illustrated, the roll support device 1 includes a plurality of types of third guide members, which serve as the third guide members 13. In the plurality of types of third guide members, at least one of a dimension of the fixed portion 13a in the axial direction X of the shaft portion 10 and a position of the regulation portion 13b in the axial direction X of the fixed portion 13a, is different.
Note that the number of each of the plurality of types of second guide members 12 and the plurality of types of third guide members 13, is not limited. The second guide member 12 and the third guide member 13 of the number capable of addressing the range of the widths of a plurality of types of roll paper 5 used in the roll support device 1, are provided.
Here, a state, in which a plurality of types of second guide members 12A and 12B is attached to the roll support device 1, will be described.
When an end of the fixed portion 12a on a side close to the regulation portion 12b is fixed to the shaft portion 10 so as to come to the side of the shaft portion 10 as illustrated in
Furthermore, when the orientation of the second guide member 12A in the axial direction X of the shaft portion 10 is changed to an orientation opposite to the orientation in
Next, as illustrated in
When the orientation of the second guide member 12B in the axial direction X of the shaft portion 10, is changed to an orientation opposite to the orientation in
Similarly to the plurality of types of second guide members 12A and 12B, a plurality of types of third guide members (not illustrated) is selectively attached to the roll support device 1. One of the plurality of types of third guide members is fixed on the base 14 in a predetermined orientation, so that the position of the regulation surface 13c of the regulation portion 13b can be switched in accordance with the width of the roll paper 5.
As described above, the roll support device 1 of the first embodiment includes the shaft portion 10, which supports the center hole 5c of the roll paper 5 (through hole of core 5b), the first guide member 11, with which the left end surface 5L of the roll paper 5 is in contact, the second guide member 12, which regulates the inner peripheral side of the right end surface 5R of the roll paper 5 in the axial direction X, and the third guide member 13, which regulates the outer peripheral side of the right end surface 5R of the roll paper 5 in the axial direction X. Thus, for example, the second guide member 12 is passed through the center hole 5c of the roll paper 5 to lower the roll paper 5 by the weight of the roll paper 5 itself. This allows the right end surface 5R of the roll paper 5 to be regulated in the axial direction by the second guide member 12 and the third guide member 13 without attaching/detaching the second guide member 12 and the third guide member 13. Therefore, an operation of attaching/detaching the roll paper 5 to/from the roll support device 1 can be easily performed, and the operability at the time of replacing the roll paper 5 can be enhanced. Furthermore, according to the roll support device 1, the second guide member 12 and the third guide member 13 can be fixedly provided on the roll support device 1, so that the loss of the second guide member 12 and the third guide member 13 can be prevented.
Furthermore, in the roll support device 1 of the first embodiment, the height H of the second guide member 12 in the radial direction of the roll paper 5, supported by the shaft portion 10, is smaller than the inner diameter D of the center hole 5c of the roll paper 5. This allows the second guide member 12 to be smoothly passed through the center hole 5c of the roll paper 5, and allows the roll paper 5 to be easily supported by the shaft portion 10. Therefore, the operability at the time of replacing the roll paper 5 can be further improved.
Furthermore, in the roll support device 1 of the first embodiment, the sum of the radial upper range A1 of the right end surface 5R regulated by the second guide member 12 and the radial lower range A2 of the right end surface 5R regulated by the third guide member 13 is equal to or larger than the entire range A3 from the inner periphery to the outer periphery of the right end surface 5R in the radial direction of the roll paper 5 supported by the shaft portion 10. This allows the regulation surface 12c of the second guide member 12 and the regulation surface 13c of the third guide member 13 to cooperate with each other to regulate the radial portion of the right end surface 5R of the roll paper 5 from the inner periphery to the outer periphery, and allows the roll paper 5 to be appropriately regulated in the axial direction X.
Furthermore, each of the second guide member 12 and the third guide member 13 in the roll support device 1 of the first embodiment is provided such that each position in the axial direction X of the shaft portion 10 can be adjusted. Thus, the roll paper 5 can be appropriately regulated by the second guide member 12 and the third guide member 13 by appropriately adjusting and fixing each of the positions of the second guide member 12 and the third guide member 13 while the pieces of roll paper 5 having different widths can be supported on the shaft portion 10.
Furthermore, each of the second guide member 12 and the third guide member 13 in the roll support device 1 of the first embodiment includes the fixed portions 12a and 13a, which are fixed to an end of the shaft portion, and the regulation portions 12b and 13b, which extend along the radial direction of the roll paper 5 from the fixed portions 12a and 13a, and regulate the inner peripheral side of the right end surface 5R. Each of the second guide member 12 and the third guide member 13 is provided so as to be attached in an orientation opposite to the axial direction X of the shaft portion 10. Thus, the pieces of roll paper 5, having different widths, can be supported on the shaft portion 10, by attaching each of the second guide member 12 and the third guide member 13 on the shaft portion 10 after switching the orientation of the shaft portion 10 in the axial direction X, and the convenience of the roll support device 1 can be improved.
Furthermore, the roll support device 1 of the first embodiment includes a plurality of types of second guide members 12 and a plurality of types of third guide members 13, which have different positions of the regulation portions in the axial direction of the fixed portion. Thus, a plurality of types of roll paper 5, having different widths, can be supported on the shaft portion 10 by selectively using one of the plurality of types of second guide members 12 and one of the plurality of types of third guide members 13, and the convenience of the roll support device 1 can be further improved.
A second embodiment will be described below with reference to the drawings. In the second embodiment, the same reference signs as those in the first embodiment are attached to the same components as those in the first embodiment, and the description thereof will be omitted. The second embodiment is different from the first embodiment in that a regulation portion of a third guide member is turnably provided.
As illustrated in
The third guide member 23 is disposed on the side of the right end surface 5R of the roll paper 5, supported by the shaft portion 10, and detachably provided on a base 14 below a second guide member 12. As illustrated in
The regulation portion 23b is provided at the fixed portion 23a so as to turn around a turning shaft 24. The regulation portion 23b turns from a regulation position, at which the regulation portion 23b stands from the fixed portion 23a to follow the right end surface 5R of the roll paper 5, to a retraction position, at which the regulation portion 23b is separated from the right end surface 5R of the roll paper 5 to follow the base 14. A torsion coil spring (not illustrated), which biases the regulation portion 23b in a direction of turning from the retraction position to the regulation position, is provided around the turning shaft 24 in the fixed portion 23a.
The regulation portion 23b has a flat plate shape, which has a regulation surface 23c in contact with the right end surface 5R of the roll paper 5. The regulation portion 23b extends in the Z direction upward from the fixed portion 23a to the vicinity of the shaft portion 10, and extends along a Y-axis toward the rear of the roll support device 2 to the outer periphery of the roll paper 5. The regulation portion 23b of the third guide member 23 is in contact with the right end surface 5R from the inner periphery to the outer periphery on the lower side of the right end surface 5R of the roll paper 5. Therefore, the regulation portion 23b of the third guide member 23 secures a regulation surface 23c larger than that of the regulation portion 13b of the third guide member 13 in the first embodiment, so that the right end surface 5R of the roll paper 5 can be regulated more stably.
Furthermore, the regulation portion 23b is turnably provided at the fixed portion 23a, so that the roll paper 5 can be supported on the shaft portion 10 by turning the regulation portion 23b that secures the large regulation surface 23c. In other words, the large regulation surface 23c of the regulation portion 23b can be secured by turnably providing the regulation portion 23b at the fixed portion 23a.
Furthermore, the fixed portion 23a of the third guide member 23 is provided such that the fixing position of the fixed portion 23a on the base 14 can be adjusted in the axial direction X of the shaft portion 10, similarly to the above-described third guide member 13. The regulation surface 23c of the third guide member 23 is fixed at a position coinciding with that of the regulation surface 12c of the second guide member 12 in the axial direction X of the shaft portion 10.
Note that, although not illustrated, an engaging portion for engaging an upper end of the third guide member 23 with the second guide member 12, may be provided on the third guide member 23. Furthermore, the regulation portion 23b of the third guide member 23 may extend upward from the fixed portion 23a to the outer periphery of the upper end of the roll paper 5 in the height direction Z. Expanding the regulation surface 23c of the regulation portion 23b can further stabilize the regulation state of the roll paper 5 in the width direction (X direction). Also in this case, the position of the regulation surface 23c of the regulation portion 23b of the third guide member 23 coincides with the position of the regulation surface 12c of the second guide member 12.
(Attachment of Roll Paper)
Also in the second embodiment, as illustrated in
Next, as illustrated in
Therefore, when the center hole 5c of the roll paper 5 is supported by the shaft portion 10, the regulation surface 12c of the second guide member 12 is in contact with the inner peripheral side of the right end surface 5R of the roll paper 5 while the regulation surface 23c of the third guide member 23 is in contact with the inner periphery to the outer periphery of the lower side of the right end surface 5R of the roll paper 5. Therefore, the left end surface 5L of the roll paper 5, whose center hole 5c is supported by the shaft portion 10, is regulated by the reference surface 11a of the first guide member 11 over the radial direction in the axial direction X. The roll paper 5 is regulated by the regulation surface 12c of the second guide member 12 and the regulation surface 23c of the third guide member 23 from the inner periphery to the outer periphery of the right end surface 5R in the axial direction X.
As described above, the third guide member 23 in the roll support device 2 of the second embodiment is provided so as to turn in a direction away from the right end surface 5R of the roll paper 5. As a result, the regulation portion 23b is turnably provided at the fixed portion 23a, so that the roll paper 5 can be supported on the shaft portion 10 by turning the regulation portion 23b that secures the large regulation surface 23c. That is, the large regulation surface 23c of the regulation portion 23b can be secured by turnably providing the regulation portion 23b at the fixed portion 23a. Therefore, the third guide member 23 can enhance the stability of the regulation state of the roll paper 5 while enhancing the operability at the time of replacing the roll paper 5.
Furthermore, also in the roll support device 2 of the second embodiment, similarly to the first embodiment, the right end surface 5R of the roll paper 5 can be regulated in the axial direction by the second guide member 12 and the third guide member 23 without attaching/detaching the second guide member 12 and the third guide member 23. Therefore, an operation of attaching/detaching the roll paper 5 to/from the roll support device 2 can be easily performed, and the operability at the time of replacing the roll paper 5 can be enhanced.
One aspect of a roll support device disclosed in the present application can enhance operability at the time of replacing a rolled medium.
