Description

[Technical field]

[0001] The present invention relates to a winding roller that winds up a strip such as a label mount from which a label has been peeled off. [Background technology]

[0002] There is known a label application device that has a pay-out roller that pays out a label base material consisting of a label and a label mount downstream, a label application mechanism that applies a label to an object to which the label is to be applied, and a wind-up roller that is equipped with a wind-up roller that winds up the label mount from which the label has been peeled off.

[0003] The label mount taken up by the take-up roller of such a label application device is subjected to a tensile force, so that the label mount is tightly wound around the circumferential surface of the take-up roller, which makes it difficult to remove the taken-up label mount from the take-up roller.

[0004] In order to solve such a problem, a pair of notched grooves into which both ends of the U-shaped pin are inserted is provided on the outer peripheral surface of the take-up bobbin along the axial direction of the take-up bobbin, the depth of the notched grooves at the base end of the take-up bobbin is shallower than the depth of the notched grooves at the tip end of the take-up bobbin, the U-shaped pin is composed of a straight portion that engages with the notched grooves of the take-up bobbin and a connecting portion that connects the base ends of the straight portions, the connecting portion is bent with respect to both straight portions, and a step is formed at the base end of the straight portion so that the tips of both straight portions ride on the tip end of the take-up bobbin when the tips of both straight portions ride on the base end of the take-up bobbin (see, for example, Patent Document 1). With this configuration, the wound label mount can be loosened by removing the U-shaped pin, so that the label mount can be easily removed.

[0005] Also, a take-up roller for winding up a strip-shaped release liner includes a roller body formed in a cylindrical shape and having an axially extending groove formed on its outer circumferential surface, a clamping part formed in a rod shape and insertable into the groove so that its longitudinal direction coincides with the extension direction of the groove and that a portion of the clamping part protrudes from the outer circumferential surface, and further, the clamping part is rotatable about an axis extending in the longitudinal direction when inserted into the groove, and a rotation restricting means restricts rotation of the clamping part relative to the groove when the clamping part is inserted into the groove, wherein the clamping part has a clamping portion that clamps the release liner between itself and the groove, and the clamping portion has a width in a cross section perpendicular to the axial direction of the clamping part, the clamping portion being rotatable about an axis extending in the longitudinal direction when inserted into the groove, is formed into a shape in which a dimension in a first direction perpendicular to the axial direction is set to be longer than a dimension in a second direction perpendicular to the axial direction and the first direction, a length of the clamping portion protruding from the outer peripheral surface of the roller body when the first direction of the clamping portion is oriented in the radial direction of the roller body is longer than a length of the clamping portion protruding from the outer peripheral surface of the roller body when the second direction of the clamping portion is oriented in the radial direction of the roller body, and the rotation regulating means regulates the rotation of the clamping portion relative to the groove portion so as to maintain the first direction at the clamping portion oriented in the radial direction of the roller body (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 3-18543 [Patent Document 2] Patent No. 6418494 Summary of the Invention [Problem to be solved by the invention]

[0007] In the case of the configuration described in Patent Document 1, the pressure of the wound label mount is applied to the U-shaped pin, which causes problems such as the need for a strong force to remove the U-shaped pin and the risk of losing the pin after it is removed.

[0008] The clamping portion of Patent Document 2 is cylindrical and rotates around the center of the clamping portion in the groove. In the state where the first direction is oriented radially and receives strong pressure from the rolled release liner, it is clear that the posture of the cylindrical clamping portion without any particular snagging is not maintained by the rotation restriction means alone, but requires support from the wall surface of the groove. Therefore, the dimensions of the clamping portion must be formed such that the dimension in the second direction is approximately the width of the groove so that the bottom and side surfaces of the clamping portion are sufficiently supported by the groove when the first direction is oriented radially. In addition, when the second direction is oriented radially, if the dimension in the first direction is significantly greater than the width of the groove, the end of the first direction may get caught on the edge of the groove, making it difficult to rotate the clamping portion, or the first direction of the clamping portion may not fit into the groove, causing the clamping portion to be significantly raised from the groove, so the dimension in the first direction must also be formed approximately the width of the groove. For this reason, in the case of the configuration described in Patent Document 2, the difference between the dimension in the first direction and the dimension in the second direction of the clamped portion cannot be made large, so the deflection that occurs in the rolled up release liner becomes small, resulting in problems such as the difficulty of pulling out the release liner not being completely resolved.

[0009] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a winding roller that enables a strip, such as a release liner, wound around the winding roller to be easily removed from the winding roller. [Means for solving the problem]

[0010] In order to achieve the above object, the invention described in claim 1 is a winding roller for winding up a strip, comprising: a roller body having a groove portion extending in the axial direction on the outer circumferential surface of a cylindrical portion; and a strip receiving portion formed into a rectangular plate-like body, arranged in the groove portion so that its longitudinal direction is along the axial direction of the roller body, with one long side protruding outward from the groove portion and the other long side located within the groove portion, and supported rotatably within the groove portion with the other long side as a fulcrum, the strip receiving portion having a rod-shaped shaft portion along the axial direction of the roller body at both ends of the other long side, the roller body having support portions at both ends in the axial direction for rotatably supporting the strip receiving portion within the groove portion with the shaft portion as a rotation axis, the shaft portion being connected to an operating portion having a rotation operating means for rotating the shaft portion at least in any direction in the axial direction, and a holding means for releasably holding the strip receiving portion in an upright state within the groove portion of the roller body. The holding means provided on the operating section is provided at a position facing the end of the roller body on the operating section, and has a plunger having a protruding portion that protrudes toward the end of the roller body in a manner that allows it to be retracted, and a holding hole portion provided on the end side of the roller body and into which the protruding portion of the plunger is removably fitted, and when the band-shaped body receiving portion rotated by the rotation operating means is in an upright state within the groove portion, the protruding portion of the plunger is fitted into the holding hole portion. It is characterized by:

[0011] According to the invention described in claim 1, when winding the strip, the operating part is operated to rotate the shaft parts at both ends of the other long side of the strip receiving part using the rotation operating means, causing the strip receiving part to stand up within the groove part of the roller body and to be held in the upright state by the holding means, and when the strip is wound around the winding roller in this state, the part of the wound strip that is received by the upright strip receiving part is lifted up and wound up in a bulging state. When the wound strip is to be removed from the winding roller, the operating part is operated to release the hold by the holding means, and the shaft part is rotated by the rotation operating means to rotate the upright strip receiving part so that it falls over. This causes the strip receiving part which holds the strip wound around the winding roller to move away from the strip, creating a gap between the roller body and the strip, loosening the grip of the strip on the winding roller, and allowing the wound strip roll to be easily removed from the winding roller.

[0012] Furthermore, since the upright state of the strip receiving part can be maintained by manipulating the shaft part, even if there is a large difference in the amount of protrusion of the strip receiving part from the groove part when the strip is being wound and when winding is completed, the upright state of the strip receiving part is not affected, and the upright state can be reliably maintained.

[0013] Furthermore, there is no need to remove the belt receiving portion from the roller body in order to loosen the tension of the belt on the winding roller, and the problem of losing the belt does not occur. In addition, the holding means provided on the operating unit is provided at a position opposite to the end of the roller body of the operating unit, and has a plunger having a protrusion that protrudes and retracts toward the end of the roller body, and a hole portion on the end side of the roller body into which the protrusion of the plunger can be removably fitted, so that when the band-shaped body receiving portion is rotated by the rotation operating means and reaches an upright position within the groove portion, the protrusion of the plunger fits into the hole portion.Therefore, by a simple operation of rotating the band-shaped body receiving portion by the rotation operating means, the band-shaped body receiving portion can be held in an upright position within the groove of the roller body, and the held state can be released.

[0014] The invention described in claim 2 is characterized in that the support portions attached to both ends of the roller body described in claim 1 are formed with support holes into which shaft portions at both ends of the other long side of the strip-shaped body receiving portion are freely rotatably fitted.

[0015] According to the invention described in claim 2, the support portions attached to both ends of the roller body are formed with support holes into which the shaft portions at both ends of the other long side of the strip-shaped body receiving portion are rotatably fitted. Therefore, by fitting the shaft portions into the support holes formed in the support portion, the support portion can rotatably support the strip-shaped body receiving portion with the shaft portions as a fulcrum.

[0016] The invention described in claim 3 is characterized in that the rotation operating means provided in the operating unit described in claim 1 or 2 is formed by attaching a lever with a handle to the shaft portion at the other end of the other long side of the band-shaped body receiving portion.

[0017] According to the invention described in claim 3, the rotation operating means provided in the operating unit is formed by attaching a lever with a handle to the axis portion at one end of the other long side of the band-shaped body receiving part, so that the band-shaped body receiving part can be easily rotated by turning the lever attached to the axis portion of the band-shaped body receiving part with the handle.

[0020] Claim 4 The invention described in claim 2 to The support holes of the support parts attached to both ends of the roller body described in the present invention have a straight line portion that is approximately perpendicular to a radial line extending from the axis of the roller body, and the shaft portion of the strip-shaped body receiving part that is fitted into the support hole is capable of moving within the support hole along the straight line portion.

[0021] Claim 4 According to the invention described in, when the upright band receiving part is rotated and tilted, the shaft part of the band receiving part that abuts the straight part in the support hole is moved along the straight part in the support hole in the opposite direction to the tilting direction of the band receiving part, so that the band receiving part retracts by the distance that the shaft has moved in the opposite direction to the tilting direction, and the inclination angle of the band receiving part when tilted becomes large, so that the amount of protrusion of the band receiving part from the groove can be further reduced. This makes it possible to make the gap between the winding roller and the band larger than when the shaft does not move, and makes it easier to remove the wound band roll from the winding roller.

[0022] Claim 5 The invention described in claim 1 3 The strip receiving portion described in any one of the above items is characterized in that it opens to the other end side of the roller body where the shaft is not attached, and has a notch portion extending toward one end side of the roller body, into which the end of the strip can be inserted.

[0023] Claim 5 According to the invention described in the above, the strip receiving portion opens to the other end side of the roller body where the shaft is not attached, and has a notch extending toward one end side of the roller body into which the end of the strip can be inserted.Therefore, by inserting the tip of the strip into the notch and folding it back, the tip of the strip can be held on the winding roller, and the strip can be easily set on the winding roller.

[0024] The invention described in claim 6 is 2 The band receiving portion according to the embodiment of the present invention is a notch portion that opens toward the other end of the roller body to which the shaft is not attached and extends toward one end of the roller body, into which the end of the band-shaped body can be inserted; The other long side formed by the notch is formed into a rod shape, and the long side serves as the shaft portion that fits into the support hole.

[0025] Claim 6 According to the invention described in the above, the band-shaped body receiving portion has a long piece portion on the other long side formed by the cutout portion formed into a rod shape, and the long piece portion serves as the shaft portion that fits into the support hole, so that the shaft portion can be easily formed. Effect of the Invention

[0026] According to the winding roller of the present invention, a winding roller can be obtained that allows a strip-shaped material, such as a release liner, wound around the winding roller to be easily removed from the winding roller. [Brief description of the drawings]

[0029] The winding roller 1 according to this example is provided in a label application device (not shown) that sequentially applies labels to product packaging containers, cardboard boxes, etc. The label application device is a device that uses a feed roller to pay out a label base material, on which labels with product information, delivery destinations, etc. printed thereon are continuously applied in the longitudinal direction to a label mount, and sequentially applies the labels peeled off from the label mount by an application mechanism to product packaging containers or cardboard boxes.

[0030] The winding roller 1 is supported circumferentially rotatably by the label application device main body (not shown) via a shaft 2. The winding roller 1 is rotated by a drive mechanism provided in the label application device main body, and the rotation direction and rotation speed can be changed by operating the drive mechanism. The winding roller rotates in accordance with the speed at which the label base material is fed out by the feed roller, and winds up and collects the label mount (hereinafter referred to as the strip) from which the labels have been peeled off.

[0031] The winding roller 1 comprises a roller body 5 having a groove portion 4 extending axially on the outer peripheral surface of a cylindrical portion 3, and a band-shaped body receiving portion 6 formed into a rectangular plate-like body, with the longitudinal direction within the groove portion 4 aligned along the axial direction of the roller body 5, one long side 6a protruding outward from the groove portion 4 and the other long side 6b located within the groove portion 4, and rotatably supported within the groove portion 4 with the other long side 6b as a fulcrum.

[0032] The strip-shaped body receiving portion 6 has a rod-shaped shaft portion 7 along the axial direction of the roller body 5 at both ends on the other long side 6b, and the roller body 5 has support portions 8 and 9 at both axial ends 5a and 5b that support the strip-shaped body receiving portion 6 rotatably within the groove portion 4 with the shaft portions 7 as the rotation axis.

[0033] The shaft portion 7 is connected, at least in any of the axial directions, to an operating portion 12 having a rotation operating means 10 for rotating the shaft portion 7 and a holding means 11 for releasably holding the strip-shaped body receiving portion 6 in an upright position within the groove portion 4 in the roller body 5.

[0034] Here, the standing state of the band-shaped body receiving portion 6 refers to a state in which the band-shaped body receiving portion 6 stands up from the groove portion 4 so that the short direction of the band-shaped body receiving portion 6 is aligned with the radial direction of the roller body 5.

[0035] The roller body 5 has a shaft 2 attached to one axial end 5a thereof, the shaft 2 being driven by a drive mechanism provided in the label application device body to rotate the roller body 5.

[0036] The groove 4 formed in the outer peripheral surface of the cylindrical portion 3 constituting the roller body 5 is formed deep enough so as not to block the support holes formed in the support portions 8 and 9, which will be described later. The width of the groove 4 limits the range in which the band-shaped body receiving portion 6 can rotate, and the wider the width, the larger the range in which the band-shaped body receiving portion 6 can rotate. The width of the groove 4 is not particularly limited, but it is preferably wide enough so that when the band-shaped body receiving portion 6 standing upright in the groove 4 is rotated and laid down, the end of one long side 6a of the band-shaped body receiving portion 6 protruding from the outer periphery of the roller body 5 abuts against the open end of the groove 4.

[0037] In this example, the cross section of the groove 4 is U-shaped, and a chamfered portion 13 is formed at the top of the wall surface 4a of the groove 4 against which the rotated and inclined band-shaped body receiving portion 6 abuts. By forming the chamfered portion 13 at the top of the wall surface 4a of the groove 4, the range in which the band-shaped body receiving portion 6 can be rotated can be made wider than when the chamfered portion 13 is not formed. The shape of the groove 4 is not limited to the shape of this example, and other shapes such as a U-shape may be adopted.

[0038] The support portions 8 and 9 provided at both axial ends 5a and 5b of the roller body 5 will be described.

[0039] The support portion 8 provided at one end 5a of the roller body 5 to which the shaft 2 is attached is formed in a plate shape and is attached to the one end 5a with a screw 14.

[0040] The support portion 8 is formed with a support hole 15 that opens into the groove portion 4 in the roller body 5 and into which the shaft portion 7a on the other end side of the band-shaped body receiving portion 6 is rotatably fitted.

[0041] The support hole 15 is formed at a position where one long side 6a of the band-shaped body receiving portion 6 can protrude from the groove portion 4 when the shaft portion 7 of the band-shaped body receiving portion 6 is fitted together with a support hole formed in the support portion 9 described later.

[0042] In this example, the support hole 15 is formed to have a straight portion 15a that is approximately perpendicular to a radial line extending from the axis of the roller body 5. This allows the shaft portion 7a fitted into the support hole 15 to move within the support hole 15 along the straight portion 15a.

[0043] In addition, the support portion 8 is formed with a shield portion 16 for preventing the strip from shifting or coming off when being wound up.

[0044] Further, the support portion 8 is formed with an insertion hole 17 into which the shaft 2 is inserted, and a hole 18 through which the screw 14 passes.

[0045] The support portion 9 provided at the other end portion 5b of the roller body 5 is formed in a plate shape, and is attached to the other end portion 5b with a screw 19.

[0046] Like support portion 8, support portion 9 has a support hole 20 that opens into groove portion 4 in roller body 5 and rotatably fits onto shaft portion 7b on the other end side of strip-shaped body receiving portion 6.

[0047] The support hole 20 is formed to face the support hole 15 of the support part 8. In other words, the support hole 20 is formed at a position where one long side 6a of the band-shaped body receiving part 6 protrudes from the groove part 4 when the shaft part 7 of the band-shaped body receiving part 6 is fitted together with the support hole 15 formed in the support part 8.

[0048] In this example, the support hole 20, like the support hole 15 of the support part 8, is formed to have a straight line portion 20a that is approximately perpendicular to a radial line extending from the axis of the roller body 5. This allows the shaft portion 7b of the belt-shaped body receiving part 6 that is fitted into the support hole 20a to move within the support hole 20 along the straight line portion 20a.

[0049] In addition, the support portion 9, together with a plunger described later, constitutes a holding means 11, and is formed with a holding hole portion 21 into which the protrusion of the plunger can be removably fitted to hold the band-shaped body receiving portion 6 in an upright position, and a hole portion 22 which holds the band-shaped body receiving portion 6 in a released upright position.

[0050] Further, the support portion 9 is formed with a hole 23 through which the screw 19 passes.

[0051] The length of the strip receiving portion 6 in the longitudinal direction is formed to be equal to or greater than the width of the strip to be wound, and the length in the transverse direction is formed to be a length that protrudes from the groove portion 4. The thickness of the strip receiving portion 6 is not particularly limited, and is formed to a thickness that can withstand the pressure from the wound strip according to the material. Examples of materials used for the strip receiving portion 6 include metal and highly rigid synthetic resin.

[0052] In this example, the band receiving portion 6 has a notch 24 that opens toward the other end 5b of the roller body 5 where the shaft 2 is not attached, and extends toward one end 5a of the roller body 5, into which the end of the band can be inserted. The length of the notch 24 in the longitudinal direction is formed to be at least as long as the width of the band to be wound up.

[0053] The shafts 7 at both ends of the other long side 6b of the band-shaped body receiving part 6 are not particularly limited as long as they can rotatably fit into the support holes 15, 20 of the support parts 8, 9. For example, the shafts 7 may be formed by protruding rod-shaped parts from both ends of the other long side 6b of the band-shaped body receiving part 6 formed on a rectangular plate.

[0054] In this example, the long piece portion 6c on the other long side 6b side formed by the cutout portion 24 formed in the band-shaped body receiving portion 6 is formed into a rod shape, which serves as the shaft portion 7.

[0055] In this example, the rotation operation means 10 of the operation unit 12 is configured by attaching a lever 26 with a handle 25 to the shaft 7b on the other end side of the band-shaped body receiving part 6. By turning the lever 26 with the handle 25, the band-shaped body receiving part 6 is rotated via the shaft 7b. Note that the rotation operation means 10 is not limited to this example, and other configurations can be adopted as long as they can rotate the shaft 7.

[0056] In this example, the shaft portion 7b on the other end side is made to protrude from the support hole 20 of the support portion 9, and this protruding portion serves as a lever attachment portion 27. A hole 29 for attaching a lever 26 with a screw 28 is formed in the lever attachment portion 27.

[0057] In this example, the holding means 11 of the operating part 12 is provided at a position opposite to the support part 9 attached to the other end 5b of the roller body 5 of the lever 26 constituting the rotation operating means 10, and is composed of a plunger 31 having a protrusion 30 that is biased toward the support part 9 and protrudes and retracts, and a holding hole portion 21 formed in the support part 9 into which the protrusion 30 of the plunger 31 is removably fitted.

[0058] In this embodiment, the operating unit 12 is configured so that the band-like body receiving part 6 is in an upright state when the lever 26 of the rotating means 10 is rotated to a position where the protrusion 30 of the plunger 31 of the holding means 11 fits into the holding hole 21. In this embodiment, the upright state of the band-like body receiving part 6 is a state in which the short direction of the band-like body receiving part 6 is aligned with the radial direction of the roller body 5. By setting this state as the upright state, the position can be maintained even when strong pressure is applied from the band.

[0059] In addition, when lever 26 is rotated so that protrusion 30 of plunger 31 is positioned to fit into retaining hole 22, band-shaped body receiving portion 6, which is in an upright state, is rotated, and when it reaches the maximum rotation position from the upright state, protrusion 30 fits into hole 22 formed in support portion 9, so that band-shaped body receiving portion 6 is held in the same position.

[0060] In addition, the plunger 31 is provided with a knob 32 for retracting the protrusion 30 in the protruding state, and by pulling the knob 32, the protrusion 30 engaged with the holding hole portion 21 and the hole portion 22 can be removed from the holding hole portion 21 and the hole portion 22.

[0061] The winding roller having the above configuration is used as follows. When winding up the band A made of a label mount, first, the handle 25 is used to turn the lever 26 to fit the protrusion 30 of the plunger 31 into the holding hole 21, thereby holding the band receiving portion 6 in an upright position.

[0062] Then, the leading end of the strip A is pulled out from the roll of the strip A arranged upstream of the label application device and wound around the winding roller 1. To wind the strip A around the winding roller 1, the leading end of the strip A is inserted into the cutout 24 formed in the strip receiving portion 6 and folded back onto the strip receiving portion 6 protruding from the outer circumferential surface of the roller body 5 (see FIG. 13), and then the winding roller 1 is manually rotated to wind the leading end of the strip A around the winding roller 1 so that it does not come off (see FIG. 14).

[0063] Once wrapping of the strip A is complete, the labeling device is started and the labels are attached. The strip A from which the labels have been peeled off is taken up by the take-up roller 1 which is rotated by a drive mechanism provided in the main body of the labeling device. The part of the taken-up strip A received by the standing strip receiving section 6 is lifted up, and the strip A becomes a bulged roll (see FIG. 15).

[0064] After the labels have been attached, the strip roll B, which has been wound around the winding roller 1 and has become a roll, can be removed from the winding roller 1 by first pulling the knob 32 on the plunger 31, retracting the protrusion 30 that is fitted into the holding hole 21 and removing it from the holding hole 21, thereby releasing the upright state of the strip receiving portion 6.

[0065] After the band-like body receiving part 6 is released from its upright position, the lever 26 is turned with the handle 25 to rotate and tilt the band-like body receiving part 6 (see FIG. 16). The band-like body receiving part 6 is rotated to its maximum rotation position, at which point the protrusion 30 of the plunger 31 is fitted into the hole 22. At this time, in this example, since the straight portions 15a, 20a are formed in the support holes 15, 20, as the band-like body receiving part 6 rotates, the shaft portion 7 moves along the straight portions 15a, 20a in the direction opposite to the direction in which the band-like body receiving part 6 was tilted, and the band-like body receiving part 6 retracts in the direction opposite to the direction in which it was tilted by the length that the shaft 7 has moved.

[0066] When the band receiving portion 6 is tilted and retracted in the opposite direction to the tilted direction by the distance that the shaft 7 has moved, the amount by which the band receiving portion 6 protrudes from the groove 4 becomes smaller than when it is in the upright state. In other words, when the band receiving portion 6 is tilted and retracted in the opposite direction to the tilted direction by the distance that the shaft 7 has moved, the length from the protruding end of the band receiving portion 6 to the axis of the roller body 5 becomes shorter than when it is in the upright state. As a result, the band receiving portion 6 that is receiving the band A moves away from the band A, a gap S is generated between the roller body 5 and the band A, and the band A is no longer tightly fastened to the winding roller 1 (see FIG. 16). In this state, the strip roll B is removed from the winding roller 1.

[0067] The winding roller 1 as described above includes a roller body 5 having a groove portion 4 extending in the axial direction on the outer circumferential surface of the cylindrical portion 3, and a band-shaped body receiving portion 6 formed in a rectangular plate shape and disposed in the groove portion 4 so that its longitudinal direction is along the axial direction of the roller body 5, with one long side 6a protruding outward from the groove portion 4 and the other long side 6b located within the groove portion 4, and supported rotatably within the groove portion 4 with the other long side 6b as a fulcrum. The band-shaped body receiving portion 6 has a rod-shaped shaft portion 7 along the axial direction of the roller body 5 at both ends on the other long side 6b side, and support portions 8 at both ends 5a, 5b of the roller body 5 support the band-shaped body receiving portion 6 rotatably within the groove portion 4 having the roller body 5 with the shaft portion 7 as a rotation axis. , 9 is attached to the winding roller 1, and further comprises an operating unit 12 having a rotation operating means 10 for rotating the shaft portion 7 and a holding means 11 for releasably holding the strip receiving portion 6 in an upright state within the groove portion 4 of the roller body 5. Therefore, when winding up the strip A, the operating unit 12 is operated to rotate the shaft portions 7 at both ends of the other long side 6b of the strip receiving portion 6 using the rotation operating means 10, causing the strip receiving portion 6 to stand up within the groove portion 4 of the roller body 5 and holding it in the upright state by the holding means 11. By winding up the strip A on the winding roller 1 in this state, the portion of the wound strip A received by the upright strip receiving portion 6 is lifted up and wound up in a bulging state. When the strip A wound around the winding roller 1 is to be removed from the winding roller 1, the operating unit 12 is operated to release the holding means 11 from the holding means, and the shaft 7 is rotated using the rotation operating means 10 to rotate the upright strip receiving portion 6 so that it falls over. This reduces the amount that the strip receiving portion 6 protrudes from the groove portion 4, causing the strip receiving portion 6 that is holding the strip A to move away from the strip A, creating a gap S between the roller body 5 and the strip A, loosening the grip of the strip A on the winding roller 1, and allowing the wound strip roll B to be easily removed from the winding roller 1.

[0068] Furthermore, since the upright state of the strip receiving portion 6 can be maintained by operating the shaft portion 7, even if there is a large difference in the amount of protrusion of the strip receiving portion 6 from the groove portion 4 between when the strip is being wound and when winding is completed, the upright state of the strip receiving portion 6 is not affected, and the upright state can be reliably maintained.

[0069] Furthermore, there is no need to remove the belt-like body receiving portion 6 from the roller body 5 in order to loosen the tension of the belt-like body on the winding roller, and the problem of losing the belt-like body does not occur.

[0070] In this example, support parts 8, 9 attached to both ends 5a, 5b of the roller body 5 are formed with support holes 15, 20 into which the shaft parts 7 at both ends of the other long side 6b of the strip-shaped body receiving part 6 are rotatably fitted. Therefore, by fitting the shaft parts 7 into the support holes 15, 20, the strip-shaped body receiving part 6 can be rotatably supported by the support parts 8, 9 around the shaft parts 7.

[0071] In this example, the support holes 15, 20 of the support portions 8, 9 have straight portions 15a, 20a that are generally perpendicular to a radial line extending from the axis of the roller body 5, and the shaft portion 7 of the band-shaped body receiving portion 6 that is fitted into the support hole 15, 20 is able to move within the support hole 15, 20 along the straight portions 15a, 20a. Therefore, when the upright band-shaped body receiving portion 6 is rotated and tilted over, the shaft portion 7 of the band-shaped body receiving portion 6 that is in contact with the straight portions 15a, 20a in the support hole 15, 20 is moved within the support hole 15, 20 along the straight portions 15a, 20a, so that the band-shaped body receiving portion 6 retracts by the length that the shaft portion 7 has moved in the direction opposite to the direction in which it is tilted, and the inclination angle of the band-shaped body receiving portion 6 when tilted over becomes larger, thereby making it possible to reduce the amount by which the band-shaped body receiving portion 6 protrudes from the groove portion 4. In other words, the length from the axis of the roller body 5 to the protruding end of the strip receiving portion 6 protruding from the groove portion 4 becomes even shorter than when in the upright state, so that the gap S between the winding roller 1 and the strip A becomes larger, making it easier to remove the wound strip roll B from the winding roller 1.

[0072] In addition, in this example, the rotation operating means 10 provided in the operating unit 12 is formed by attaching a lever 26 with a handle 25 to the shaft portion 7b at one end of the other long side 6b of the band-shaped body receiving portion 6, so that the band-shaped body receiving portion 6 can be easily rotated by turning the lever 26 with the handle 25.

[0073] In addition, in this example, the holding means 11 provided in the operating part 12 is provided at a position opposite to the support part 9 attached to the other end 5b of the roller body 5 of the lever 26 constituting the rotation operating means 10, and is composed of a plunger 31 having a protrusion 30 that is biased toward the support part 9 and protrudes in a retractable manner, and a holding hole 21 formed in the support part 9 into which the protrusion 30 of the plunger 31 is removably fitted. By turning the lever 26 with the handle 25, the band-shaped body receiving part 6 is rotated via the shaft part 7b, and when the band-shaped body receiving part 6 is in an upright state, the protrusion 30 of the plunger 31 is fitted into the holding hole 21. Therefore, by a simple operation of turning the lever 26 with the handle 25 to rotate the band-shaped body receiving part 6, the band-shaped body receiving part 6 can be held in an upright state within the groove part 4 provided in the roller body 5, and the held state can be released.

[0074] In addition, in this example, the strip receiving portion 6 has a notch 24 into which the end of the strip A can be inserted. Therefore, when winding up the strip A, the tip of the strip A is inserted into the notch 24 formed in the strip receiving portion 6, folded back onto the strip receiving portion 6 protruding from the outer peripheral surface of the roller body 5, and then the winding roller 1 is manually rotated, whereby the tip of the strip A can be easily set so that it does not come off the winding roller 1.

[0075] Furthermore, in this example, the band-shaped body receiving portion 6 has the long piece portion 6c on the other long side 6b formed by the cutout portion 24 formed in a rod shape, and the long piece portion 6c serves as the shaft portion 7 that fits into the support holes 15, 20, so that the shaft portion 7 can be easily formed.
