Description

The present invention relates to a winding roller that winds up a strip of material, such as a label mount from which a label has been peeled off.

A label application device is known that has a pay-out roller that pays out a label base material consisting of a label and a label backing downstream, an application mechanism that applies a label to an object to which the label is to be applied, and a take-up roller that winds up the label backing from which the label has been peeled off.

The label mount taken up by the take-up roller of such a label application device is subjected to a tensile force, so it is tightly wound around the circumference of the take-up roller. This creates the problem that it is difficult to remove the taken-up label mount from the take-up roller.

In order to solve such problems, 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 winding bobbin along the axial direction of the winding bobbin, the depth of the notched grooves at the base end of the winding bobbin is shallower than the depth of the notched grooves at the tip end of the winding bobbin, the U-shaped pin is composed of a straight portion that engages with the notched grooves of the winding bobbin and a connecting portion that connects the base ends of the straight portions, the connecting portion is bent relative 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 winding bobbin when they are on the base end of the winding 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.

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 which is rotatable about an axis extending in the longitudinal direction when inserted into the groove, and a rotation restriction means for restricting the 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 the clamping part and the groove, and the clamping portion has a length that is perpendicular to the axial direction of the clamping part in a cross section perpendicular to the axial direction of the clamping part, and the length of the clamping part is parallel to the axial direction of the clamping part. The length of the clamping portion protruding from the outer circumferential surface of the roller body when the first direction of the clamping portion faces the radial direction of the roller body is longer than the length of the clamping portion protruding from the outer circumferential surface of the roller body when the second direction of the clamping portion faces the radial direction of the roller body, and the rotation restriction means restricts the rotation of the clamping portion relative to the groove portion so as to maintain the first direction of the clamping portion facing the radial direction of the roller body (see, for example, Patent Document 2).

Japanese Patent Application Publication No. 3-18543 Patent No. 6418494

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, so there is a problem that a strong force is required to remove the U-shaped pin. There is also a problem that the pin may be lost after being removed.

The clamping portion of Patent Document 2 is cylindrical and rotates around the center of the clamping portion within the groove. It is clear that in the state where the first direction, which receives strong pressure from the rolled release paper, is oriented radially, the posture of the clamping portion, which is cylindrical and free of any particular snagging, is not maintained by the rotation restriction means alone, but requires support from the wall 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 float significantly above 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 dimensions of the clamped portion in the first direction and the second direction cannot be made large, so the deflection of the rolled up release liner becomes small, and the difficulty of pulling out the release liner cannot be completely resolved.

The object of the present invention is to provide a winding roller that allows a strip such as a release liner wound on the winding roller to be easily removed from the winding roller.

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 and 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, and the roller body having support portions at both ends in the axial direction for supporting the strip receiving portion rotatably within the groove portion with the shaft portions as rotation axes, the shaft portions being The roller body is connected to an operating unit having a rotation operating means for rotating the shaft portion, at least in any of the axial directions, and a holding means for releasably holding the band-shaped body receiving portion in an upright state within the groove portion of the roller body, the holding means provided on the operating unit being provided at a position opposite to the end of the roller body of the operating unit, and having a plunger having a protrusion that protrudes and retracts toward the end of the roller body, and a holding hole portion on the end side of the roller body into which the protrusion 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 protrusion of the plunger fits into the holding hole portion .

According to the invention described in claim 1, when the strip is wound up, 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 in the groove part of the roller body and to be held in the upright state by the holding means. When the strip is wound up on 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 unit is operated to release the holding means, and the shaft is rotated by the rotation operating unit to rotate and tilt the standing strip receiving part. This causes the strip receiving part, which has been receiving the strip wound on the winding roller, to separate 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.

In addition, since the belt-like body receiving part can be held upright by manipulating the shaft, even if the amount of protrusion of the belt-like body receiving part from the groove is significantly different when the belt-like body is being wound up and when winding is complete, the belt-like body receiving part can be held upright without being affected, and the belt-like body receiving part can be reliably held upright.

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.

The invention described in claim 2 is characterized in that the support parts attached to both ends of the roller body described in claim 1 have support holes formed therein into which shaft parts at both ends of the other long side of the belt-shaped body receiving part are rotatably fitted.

According to the invention described in claim 2, the support parts attached to both ends of the roller body are formed with support holes into which the shaft parts at both ends of the other long side of the belt-shaped body receiving part are rotatably fitted. By fitting the shaft parts into the support holes formed in the support parts, the support parts can rotatably support the belt-shaped body receiving part with the shaft parts as a fulcrum.

The invention described in claim 3 is characterized in that the rotating operation means provided in the operation unit described in claim 1 or 2 is a lever with a handle attached to the shaft portion at the other end of the other long side of the band-shaped body receiving portion.

According to the invention described in claim 3, the rotation operation means provided in the operation unit is formed by attaching a lever with a handle to the shaft 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 shaft portion of the band-shaped body receiving part with the handle.

The invention described in claim 4 is characterized in that the support holes of the support parts attached to both ends of the roller body described in claim 2 have straight lines that are approximately perpendicular to a radial line extending from the axis of the roller body, and the shaft parts of the band-shaped body receiving parts fitted into the support holes are capable of moving within the support holes along the straight lines.

According to the invention of claim 4 , 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.

The invention described in claim 5 is characterized in that the strip-shaped body receiving portion described in any one of claims 1 to 3 has a notch portion that opens to the other end side of the roller body where the shaft is not attached, and extends toward one end side of the roller body, into which the end of the strip-shaped body can be inserted.

According to the invention described in claim 5 , 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.

The invention described in claim 6 is characterized in that the strip-shaped body receiving portion described in claim 2 opens to the other end side of the roller body where the shaft is not attached, has a notch extending toward one end side of the roller body, into which the end of the strip-shaped body can be inserted, and the long piece portion on the other long side formed by the notch portion is formed into a rod shape, and the long piece portion serves as the shaft portion that fits into the support hole.

According to the invention described in claim 6 , the band-shaped body receiving portion has a long piece portion on the other long side formed by the cutout portion formed in 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.

The winding roller according to the present invention can provide a winding roller that allows a strip such as a release liner wound around the winding roller to be easily removed from the winding roller.

The winding roller 1 in 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 payout roller to feed downstream a label base material on which labels with product information, delivery destinations, etc. printed thereon are continuously affixed 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.

The winding roller 1 is supported by the label application device main body (not shown) via a shaft 2 so that it can rotate in the circumferential direction. The winding roller 1 is rotated by a drive mechanism provided in the label application device main body, and the direction and speed of rotation 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 label has been peeled off.

The winding roller 1 is equipped with a roller body 5 having a groove portion 4 extending in the axial direction on the outer peripheral surface of the cylindrical portion 3, and a band-shaped body receiving portion 6 formed as a rectangular plate, with the longitudinal direction in the groove portion 4 aligned with 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 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 aligned with the axial direction of the roller body 5 at both ends on the other long side 6b side, and the roller body 5 has support portions 8, 9 at both axial ends 5a, 5b that support the band-shaped body receiving portion 6 rotatably in the groove portion 4 with the shaft portion 7 as the rotation axis.

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

Here, the upright state of the belt-shaped body receiving portion 6 refers to a state in which the belt-shaped body receiving portion 6 rises up from the groove portion 4 so that the short direction of the belt-shaped body receiving portion 6 is aligned with the radial direction of the roller body 5.

The roller body 5 has a shaft 2 attached to one axial end 5a, which is driven by a drive mechanism provided in the label application device body to rotate the roller body 5.

The groove 4 on the outer peripheral surface of the cylindrical portion 3 that constitutes the roller body 5 is formed deep enough so that the support holes formed in the support portions 8 and 9, which will be described later, are not blocked. 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 preferable that the width be such that when the band-shaped body receiving portion 6, which is in an upright state within the groove 4, is rotated and tilted over, the end of one long side 6a of the band-shaped body receiving portion 6 protruding from the outer peripheral surface of the roller body 5 abuts against the open end of the groove 4.

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 rotate 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 in this example, and other shapes such as a U-shape may be adopted.

The support parts 8 and 9 provided at both ends 5a and 5b of the roller body 5 in both axial directions will be described.

The support part 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.

The support portion 8 has a support hole 15 that opens into the groove portion 4 in the roller body 5 and into which the shaft portion 7a at the other end of the belt-shaped body receiving portion 6 is rotatably fitted.

The support hole 15 is formed at a position where one long side 6a of the band-shaped body receiving part 6 can protrude 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 formed in the support part 9 described later.

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

In addition, the support section 8 is formed with a shield section 16 that prevents the strip from shifting or coming off when being wound.

The support portion 8 also has an insertion hole 17 for inserting the shaft 2 and a hole 18 for passing the screw 14 through.

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

Like support part 8, support part 9 has a support hole 20 that opens into groove part 4 in roller body 5 and rotatably fits onto shaft part 7b at the other end of band-shaped body receiving part 6.

The support hole 20 is formed to face the support hole 15 of the support part 8. That is, 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.

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 generally perpendicular to a radial line extending from the axis of the roller body 5. This allows the shaft portion 7b of the band-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.

The support portion 9 also constitutes the holding means 11 together with a plunger described below, and is formed with a holding hole 21 into which the protruding portion of the plunger is removably fitted to hold the band-shaped body receiving portion 6 in an upright position, and a hole 22 that holds the band-shaped body receiving portion 6 in a released upright position.

In addition, a hole 23 is formed in the support part 9 to pass the screw 19 through.

The length of the strip receiving portion 6 in the longitudinal direction is greater than or equal to the width of the strip to be wound, and the length in the transverse direction is formed so that it protrudes from the groove portion 4. There are no particular limitations on the thickness of the strip receiving portion 6, and the thickness is formed to be in accordance with the material and capable of withstanding the pressure from the wound strip. Examples of materials used for the strip receiving portion 6 include metal and highly rigid synthetic resin.

In this example, the strip receiving portion 6 opens to the other end 5b of the roller body 5 where the shaft 2 is not attached, and has a notch 24 extending to one end 5a of the roller body 5 into which the end of the strip can be inserted. The longitudinal length of the notch 24 is formed to be at least as long as the width of the strip to be wound.

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 can 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.

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

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 the shaft 7 can be rotated.

In this example, the shaft portion 7b on the other end side protrudes from the support hole 20 of the support portion 9, and this protruding portion serves as the lever attachment portion 27. The lever attachment portion 27 has a hole 29 formed therein for attaching the lever 26 with a screw 28.

The holding means 11 of the operating part 12, in this example, is provided at a position facing 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 protruding part 30 that is biased toward the support part 9 and protrudes and retracts, and a holding hole part 21 formed in the support part 9 into which the protruding part 30 of the plunger 31 is removably fitted.

In this example, the operating unit 12 is configured so that the band-shaped 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 example, the upright state of the band-shaped body receiving part 6 is a state in which the short direction of the band-shaped 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-shaped body.

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

The plunger 31 is also provided with a knob 32 that retracts the protruding portion 30 from the protruding state, and by pulling the knob 32, the protruding portion 30 that is fitted into the holding hole portion 21 and the hole portion 22 can be removed from the holding hole portion 21 and the hole portion 22.

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 projection 30 of the plunger 31 into the holding hole 21, thereby holding the band receiving portion 6 in an upright position.

Then, the leading end of the strip A is pulled out from the roll of strip A located 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 over 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).

Once the wrapping of the strip A is complete, the labeling device is started and the label is attached. The strip A from which the label has been peeled off is wound up by the winding roller 1 which is rotated by a drive mechanism provided in the main body of the labeling device. The part of the wound strip A received by the upright strip receiving section 6 is lifted up, forming a bulged roll (see Figure 15).

After the labels have been attached, the strip roll B, which has been wound around the winding roller 1 and is now in a roll shape, 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 disengaging it from the holding hole 21, thereby releasing the upright state of the strip receiving part 6.

After releasing the band-shaped body receiving part 6 from its upright position, the lever 26 is turned with the handle 25 to rotate and tilt the band-shaped body receiving part 6 (see FIG. 16). The band-shaped 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 lines 15a, 20a are formed in the support holes 15, 20, as the band-shaped body receiving part 6 rotates, the shaft 7 moves along the straight lines 15a, 20a in the direction opposite to the direction in which the band-shaped body receiving part 6 was tilted, and the band-shaped 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.

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 axial center 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 separates from the band A, creating a gap S 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.

According to the winding roller 1 described above, the roller body 5 has a groove portion 4 extending in the axial direction on the outer peripheral surface of the cylindrical portion 3, and a band-shaped body receiving portion 6 formed in a rectangular plate-like body, arranged 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 in 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 the rotation axis. , 9 are attached to the winding roller 1, and the winding roller 1 is further equipped with 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.When the strip A is wound up, 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 the strip A around 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 by the rotation operating means 10 to rotate and tilt the standing strip receiving part 6. This reduces the amount that the strip receiving part 6 protrudes from the groove 4, so that the strip receiving part 6 that is holding the strip A separates 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 the wound strip roll B can be easily removed from the winding roller 1.

In addition, since the belt-like body receiving portion 6 can be held in an upright position by manipulating the shaft portion 7, even if the amount of protrusion of the belt-like body receiving portion 6 from the groove portion 4 is significantly different when the belt-like body is being wound and when winding is completed, the belt-like body receiving portion 6 can be held in an upright position without being affected, and the upright position can be reliably maintained.

In addition, there is no need to remove the belt receiving portion 6 from the roller body 5 to loosen the belt from the winding roller, so there is no problem with losing the belt.

In this example, the 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. By fitting the shaft parts 7 into the support holes 15, 20, the support parts 8, 9 can support the strip-shaped body receiving part 6 rotatably around the shaft parts 7.

In this example, the support holes 15, 20 of the support parts 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 part 6 that is fitted into the support holes 15, 20 can move within the support holes 15, 20 along the straight portions 15a, 20a. Therefore, when the upright band-shaped body receiving part 6 is rotated and tilted over, the shaft portion 7 of the band-shaped body receiving part 6 that is in contact with the straight portions 15a, 20a in the support holes 15, 20 is moved within the support holes 15, 20 along the straight portions 15a, 20a, so that the band-shaped body receiving part 6 retracts by the length of the shaft portion 7 moved in the direction opposite to the direction in which it is tilted, and the inclination angle of the band-shaped body receiving part 6 when tilted becomes larger, so that the amount of protrusion of the band-shaped body receiving part 6 from the groove portion 4 can be reduced. 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 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.

In addition, in this example, the rotation operation means 10 provided in the operation unit 12 is configured 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.

In this example, the holding means 11 provided in the operating unit 12 is provided at a position facing 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 protruding part 30 that is biased toward the support part 9 and protrudes in a retractable manner, and a holding hole part 21 formed in the support part 9 into which the protruding part 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 protruding part 30 of the plunger 31 is fitted into the holding hole part 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 of the roller body 5 and the held state can be released.

In addition, in this example, the band receiving portion 6 has a notch 24 into which the end of the band A can be inserted. When winding up the band A, the leading end of the band A is inserted into the notch 24 formed in the band receiving portion 6, folded back onto the band receiving portion 6 protruding from the outer circumferential surface of the roller body 5, and then the winding roller 1 is manually rotated, so that the leading end of the band A can be easily set so that it does not come off the winding roller 1.

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