Description

  The present invention relates to a take-up roller that winds a release mount.

A strip-shaped label tape in which a plurality of labels are arranged on the surface of a strip-shaped release mount (label mount) in the longitudinal direction of the release mount and temporarily attached is used, for example, in a label applicator that sequentially applies labels to a plurality of various products. It is done.
A label sticking machine is provided with a winding roller (winding device) for winding up a peeling mount after the label is peeled off, as in Patent Document 1, for example. The release mount is wound around the take-up roller in a roll shape by rotating the take-up roller after engaging one end in the longitudinal direction with the outer peripheral portion of the take-up roller.

  Patent Literature 1 discloses a winding device for easily removing a peeling mount (hereinafter referred to as a belt-like body roll) wound in a roll shape. The winding device includes a rotating shaft, a rotating member including a pin member that is integrally fixed to the rotating shaft and extends in the axial direction of the rotating shaft at a position spaced radially outward of the rotating shaft, and the rotating shaft. And a rotating core that is supported so as to be slidable in the axial direction, engages with the rotating member, and can rotate integrally with the rotating member.

  In this winding device, the rotary core is engaged with the rotary member, and the rotary shaft and the rotary member are rotated while the end of the peeling mount is sandwiched between the pin member and the outer peripheral surface of the rotary core. The mount is wound around the rotating core and the pin member in a roll shape. The roll-shaped strip roll can be removed from the rotating shaft and the rotating member together with the rotating core by sliding the rotating core in the axial direction with respect to the rotating shaft and the rotating member. In the removed state, since the tightening of the band-shaped body roll with respect to the rotating core is loosened, the band-shaped body roll can be easily detached from the rotating member.

However, in the winding device of Patent Document 1, since the belt-shaped body roll strongly tightens the rotating core and the pin member, the frictional force between the belt-shaped body roll (peeling mount) and the pin member becomes very large. For this reason, when pulling out a strip | belt-shaped body roll with a rotating core from a rotating shaft, big force is needed. That is, there is a problem that it is still difficult to remove the strip wound in a roll shape.
Moreover, the winding device of Patent Document 1 has a structure for integrally fixing the rotating shaft and the pin member, and a structure for allowing the rotating core to enter the inner peripheral side of the pin member. That is, since the winding device of Patent Document 1 is complicated, there is also a problem that its manufacturing cost is high.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a take-up roller that can easily remove a strip-shaped body roll and can be manufactured at low cost.

In order to solve this problem, the winding roller of the present invention is a winding roller that winds a strip-shaped release mount, which is formed in a columnar shape, and a roller body that has a groove extending in the axial direction on the outer peripheral surface; , And is inserted into the groove portion so that the longitudinal direction thereof coincides with the extending direction of the groove portion and a part thereof protrudes from the outer peripheral surface.

For this reason, in the state which inserted the clamping part 21 in the groove part 11 so that the 1st direction of the clamping part 22 may face the radial direction of the roller main body 10, the protrusion length of the clamping part 22 which protrudes from the outer peripheral surface 10a of the roller main body 10 However, it becomes long compared with the state (refer FIG. 6) which orient | assigned the 2nd direction of the clamping part 22 to the radial direction of the roller main body 10. FIG. In the state where the second direction of the clamping part 22 is oriented in the radial direction of the roller body 10, for example, the clamping part 22 may not protrude from the outer peripheral surface 10 a of the roller body 10.
The clamping part 22 may be formed in a semicircular cross section, for example, but is formed in a rectangular cross section in the present embodiment.

For example, the clamping part 22 may be formed in the entire part of the clamping part 21 that is inserted into the groove part 11, but in the present embodiment, the clamping part 22 is located away from the main body part 2 of the clamping part 21 that is inserted into the groove part 11. It is formed in the part except the site | part 23 by the side of the 1st end part 21A of the clamping part 21 inserted in the groove part 11 in the front-end | tip part of the roller main body 10 to perform.
The cross-sectional shape of the portion 23 on the first end 21 </ b> A side of the holding portion 21 inserted into the groove portion 11 at the distal end portion of the roller body 10 may be arbitrary, but in this embodiment, the holding portion 21 is inserted into the groove portion 11. In such a state, it is formed in a circular cross section so that it can be easily rotated around the axis A2.
The clamping part 21 comprised as mentioned above may consist of a material whose hardness is higher than the roller main body 10, for example.

Further, the present embodiment is fixed to the first end portion 21A of the clamping portion 21, an operation unit 25 that extends radially outwardly of the sandwiching portion 21 from the first end 21A. The extending direction of the operation part 25 in the radial direction of the clamping part 21 coincides with the first direction of the clamping part 22 described above. The operation unit 25 of the present embodiment is formed integrally with the holding unit 21 by bending the rod-shaped member. The operation unit 25 of the present embodiment is formed in a U shape. For this reason, the extension direction front-end | tip of the operation part 25 has faced reversely with respect to 21 A of 1st end parts of the clamping part 21. FIG. Further, in the present embodiment, the size of the operation unit 25 extending in the radial direction from the clamping unit 21 is set to be shorter than the diameter size of the roller body 10.

And a locking portion 31 that locks the rotation.

Locked portion 26 extends from the extending direction distal end of the operating portion 25 to the clamping portion 21 and the opposite, Therefore, in the state of inserting the clamping portion 21 into the groove portion 11, the locked portion 26 are roller body It extends so as to approach the tip of 10. In addition, as illustrated in FIGS. 1 and 3, the locked portion 26 is a roller in a state where the clamping portion 21 is inserted into the groove portion 11 so that the first direction of the clamping portion 22 faces the radial direction of the roller body 10. It is located radially inward from the outer peripheral surface 10a of the main body 10. The locked portion 26 of the present embodiment is formed integrally with the clamping portion 21 and the operation portion 25. That is, in this embodiment, the clamping part 21, the operation part 25, and the to-be-latched part 26 are comprised by the rod-shaped member 20 formed in the U-shape.

The locking portion 31 of the present embodiment is provided on the radially inner side of the outer peripheral surface 10a of the roller body 10. Specifically, the locking portion 31 is provided inside the hollow portion 12 formed at the tip portion of the roller body 10. The recess 12 is formed so as to be recessed radially inward from a portion of the outer peripheral surface 10a of the roller body 10 opposite to the groove 11. Further, the recess 12 is open to the tip surface 10 b of the roller body 10. Moreover, the hollow part 12 is formed so that the to-be-latched part 26 can go in and out of the hollow part 12 when the clamping part 21 arranged in the groove part 11 is rotated around its axis A2. (See FIG. 6). For this reason, as shown in FIG. 3, the bottom surface 13 of the recessed portion 12 is viewed from the front end surface 10 b side of the roller body 10 toward the left and right sides from the central portion 13 </ b> A of the bottom surface 13 located on the opposite side to the groove portion 11. Inclined in the direction approaching the groove 11 (upward in FIG. 3).

The locking portion 31 of the present embodiment is made of an elastically deformable leaf spring member. The locking portion 31 includes a fixing portion 32 that is fixed to the roller body 10 by surface contact, and a holding portion 33 that is formed continuously with the fixing portion 32 and holds the locked portion 26. The locking part 31 is formed between the fixing part 32 and the holding part 33 so as to be elastically bendable.
The fixing portion 32 of the present embodiment is fixed to one inclined portion 13B (the left inclined portion 13B in FIG. 1B) adjacent to the central portion 13A in the bottom surface 13 of the recess portion 12. The fixing part 32 may be fixed to the roller body 10 in a non-detachable manner, for example, but is fixed to the roller body 10 by screws 34 in the present embodiment.

  The holding portion 33 is arranged on the other inclined portion 13B side of the bottom surface 13 of the recessed portion 12 with respect to the fixed portion 32, and a pair of support wall portions 33A and 33B that sandwich the locked portion 26 from the circumferential direction of the roller body 10. Have The pair of support wall portions 33A and 33B may be configured by bending the leaf spring member into a V shape as illustrated, but may be configured, for example, by bending it into a U shape. The first support wall portion 33 </ b> A extends away from the bottom surface 13 of the recessed portion 12 with respect to the fixed portion 32. The second support wall portion 33B extends from the front end of the first support wall portion 33A in the extending direction to the other inclined portion 13B side of the bottom surface 13 of the recessed portion 12. The second support wall portion 33B is inclined so as to approach the bottom surface 13 (particularly, the other inclined portion 13B) of the recessed portion 12 toward the distal end in the extending direction. Although the holding part 33 may be formed in U shape, for example, in this embodiment, it is formed in V shape.

The holding portion 33 according to the present embodiment configured as described above is open to the front end surface 10 b side of the roller body 10. For this reason, the holding part 26 inserted in the groove part 11 is slid from the distal end side to the proximal end side of the roller body 10 to move the rod-like locked part 26 in the holding part 33 (a pair of support parts). Between the wall portions 33A and 33B).

Next, the operation of the winding roller 3 having the above configuration will be described.
When the peeling mount M is wound up by the winding roller 3 according to the present embodiment, first, as shown in FIG. 3, the longitudinal end portion of the peeling mount M is connected to the clamping portion 22 of the clamping portion 21 and the roller body 10. It sandwiches between the groove part 11 of. Thereby, the edge part of the peeling mount M in the longitudinal direction is fixed to the winding roller 3. Next, the rotational position of the clamping part 21 is held by the rotation restricting means 30 so that the first direction of the clamping part 22 is directed in the radial direction of the roller body 10, that is, the locked part 26 is held at the front end surface of the roller body 10. Inserted into the holding portion 33 of the locking portion 31 from the 10b side. In this state, since the pair of support wall portions 33A and 33B of the holding portion 33 sandwich the locked portion 26 from the circumferential direction of the roller body 10, the rotation of the sandwiching portion 21 is restricted.

Thereafter, the roller body 10 is rotated around the axis A1 (for example, rotated in the direction of the arrow in FIG. 3). Thereby, as shown in FIGS. 4 and 5, the release mount M is wound up in a roll shape so as to cover the outer peripheral surface 10 a of the roller body 10 and the sandwiching portion 22 of the sandwiching portion 21. At this time, since the rotation of the clamping unit 21 is regulated by the rotation regulating means 30, the clamping unit 21 does not rotate around the axis A2 when the peeling mount M is wound up.

Peeling mount M (hereinafter, referred to as a strip roll MR.) Wound in a roll in the winding roller 3 upon removal from the winding roller 3, as shown in FIG. 6, sandwiched by the rotation restricting means 30 The rotation restriction of the portion 21 may be released, and the sandwiching portion 21 may be rotated 90 degrees about its axis A2. In the present embodiment, the clamping portion 21 is rotated (rotated counterclockwise in FIG. 6) so that the locked portion 26 is directed toward the distal end side in the extending direction of the second support wall portion 33 </ b> B of the holding portion 33. The holding portion 33 is elastically bent with respect to the fixed portion 32 so that the second support wall portion 33 </ b> B is separated from the bottom surface 13 of the recessed portion 12. As a result, the locked portion 26 can be extracted outside the holding portion 33. That is, the rotation restriction of the clamping part 21 by the rotation restriction means 30 can be released.

Then, by pinching unit 21 is rotated 90 degrees about its axis A2, the second direction of the clamping portion 22 of the clamping portion 21 is oriented in the radial direction of the roller body 10. For this reason, the force which fastens the winding roller 3 by the belt-shaped body roll MR is weakened, and the frictional force between the belt-shaped body roll MR (peeling mount M) and the roller body 10 or the sandwiching part 21 is reduced or eliminated.
Finally, the clamping part 21 is pulled out from the groove part 11 in the extending direction thereof, and the strip-shaped body roll MR is pulled out toward the tip end side of the roller body 10, whereby the removal of the strip-shaped body roll MR is completed.

As described above, according to the winding roller 3 of the present embodiment, the winding device including the winding roller, and the label sticking machine 1, the winding roller 3 is simply rotated by the belt-shaped body roll MR just by rotating the clamping unit 21 by 90 degrees. Therefore, the belt-shaped roll MR can be easily detached from the winding roller 3.
Moreover, since the winding roller 3 of this embodiment is a simple structure which puts the rod-shaped clamping part 21 in the groove part 11 of the roller main body 10 formed in the column shape compared with the conventional one, manufacturing cost is reduced. It can be kept low.

Moreover, according to the winding roller 3 of this embodiment, since the operation part 25 extended to the radial direction outer side is being fixed to the clamping part 21, when removing the strip | belt-shaped body roll MR from the winding roller 3, it is small. The clamping part 21 can be easily rotated by force. That is, the strip-shaped roll MR can be removed from the winding roller 3 more easily.
Furthermore, the winding roller 3 of the present embodiment includes a roller body 10, a locking portion 31 fixed to the roller body 10, and a rod-shaped member 20 in which the clamping portion 21, the operation portion 25, and the locked portion 26 are integrally formed. It can consist of only three. That is, the manufacturing cost of the winding roller 3 can be further reduced.

Moreover, according to the winding roller 3 of this embodiment, since the latching | locking part 31 is provided in the radial inside rather than the outer peripheral surface 10a of the roller main body 10, the latching | locking part 31 makes the strip | belt-shaped body roll MR roll body. Thus, it is possible to reliably prevent obstruction when the 10 is pulled out in the axial direction.
Moreover, according to the winding roller 3 of this embodiment, since the clamping part 21 is detachable with respect to the winding roller 3, the edge part of the peeling mount M in the longitudinal direction can be easily fixed to the winding roller 3. .

Although the details of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
For example, the fixing part 32 of the locking part 31 may be fixed to at least a surface of the roller body 10 that faces radially outward, and may be fixed to the outer peripheral surface 10 a of the roller body 10, for example. That is, the latching | locking part 31 may be provided in the radial direction outer side rather than the outer peripheral surface 10a of the roller main body 10, for example.
