Description

  The present invention relates to a label peeling apparatus that peels off a label from a belt-like mount by folding back the belt-like mount on which a plurality of labels are temporarily attached. In particular, the label can be peeled by squeezing the label when peeling the label. The present invention relates to a label peeling apparatus.

Conventionally, as this kind of label peeling apparatus, what was published in the patent 4371666 gazette (patent document 1) is known, for example.
As shown in FIG. 8, the label peeling device Sa sends out a strip-like mount D on which a plurality of labels L are temporarily attached at equal intervals along the longitudinal direction, and sends the strip-like mount D along the longitudinal direction. The label L is peeled off from the belt-like mount D by folding back, and the support surface 101 and the belt-like mount D for supporting the back surface Db of the belt-like mount D with the front surface Da on which the label L of the belt-like mount D is temporarily attached facing upward. A peeling member 100 having a tip portion 102 that is folded back is provided. In the vicinity of the front end portion 102 of the support surface 101 of the peeling member 100, the strip-shaped mount D extends in a direction orthogonal to the feed back and forth direction R along the support surface 101 of the strip-shaped mount D, and the strip-shaped mount D on the support surface 101 is immersed in an arc. A groove 103 is formed. In addition, a cylindrical pressing member 104 that presses the belt-like mount D from the surface side is provided to the groove 103 that is loosely fitted to the groove 103 with a gap at the lower portion. By passing the belt-like mount D through the gap, the label L temporarily attached to the belt-like mount D is rubbed and peeled off.

  In the label peeling device Sa, the label L is peeled from the belt-like mount D, and at the position where the downstream side of the label L protrudes from the tip 102 of the peeling member 100 for a predetermined length, the feeding of the belt-like mount D is temporarily stopped. In this state, for example, the label L is taken out by hand and the label L is attached to an article (not shown), which is an adherend, or the article, which is an adherend, passes through the outside of the distal end portion 102 of the peeling member 100. The label L is affixed to the article. In this case, if the label L to be peeled is released away from the pressing member 104, the label L can be easily taken out. However, since the label L may fall, the upstream end of the label L to be peeled off Can be held by the holding member 104.

  In this way, the label L is squeezed and peeled when the adhesive force of the adhesive provided on the label L temporarily attached to the belt-like mount D is strong or due to the material or shape of the label L. Thus, there may be a peeling failure such that the label L cannot be peeled off, and the occurrence of such a peeling failure is prevented.

Japanese Patent No. 4371666

  By the way, in the conventional label peeling apparatus Sa, since the lower part of the columnar pressing member 104 is loosely fitted in the arc-shaped groove 103 provided in the peeling member 100 with a gap, the groove 103 and the pressing member Since the gap with 104 is constant, there is a difference in the degree of adhesive force of the adhesive provided on the label L, or the conditions such as the thickness and shape of the belt-like mount or label are different. There is a problem that troubles such as peeling failure in which ironing is not sufficiently performed or damage to the surface of the label L due to excessive ironing may occur.

  The present invention has been made in view of the above-mentioned problems, and the squeezing force is adjusted according to the degree of adhesive force of the adhesive provided on the label, or according to the conditions such as the thickness and shape of the belt-like mount or label. It is an object of the present invention to provide a label peeling apparatus that can adjust the thickness of the iron and ensure that the label is peeled off with proper ironing.

In order to solve the above-described problem, the label peeling apparatus of the present invention sends a belt-like mount on which a plurality of labels are temporarily attached along the longitudinal direction along the longitudinal direction. A label peeling device that peels off the label from the strip by folding,
A peeling member having a support surface for supporting the back surface of the belt-like mount with the surface on which the label of the belt-like mount is temporarily attached facing upward, and a tip portion for folding the belt-like mount, and a tip of the support surface of the peeling member A groove extending in the direction perpendicular to the feeding front-rear direction along the support surface of the belt-like mount is formed in the vicinity of the portion, and the belt-like mount on the support surface is immersed, and the belt-like mount is pressed against the groove from the surface side. In a label peeling apparatus provided with a pressing member, the label temporarily attached to the belt-shaped mount by the groove and the pressing member is peeled off.
The ironing force adjusting means for adjusting the ironing force by the pressing member is provided.

  Thereby, the ironing force of the pressing member is adjusted in advance by the ironing force adjusting means, and the label is peeled off from the belt-like mount. At this time, when the belt-shaped mount is sent out, the belt-shaped mount is supported on the support surface of the peeling member with the surface on which the label is temporarily attached facing upward, and is folded back at the tip of the peeling member. In the vicinity of the front end portion, the belt-like mount is immersed in a groove having a substantially rectangular cross section and is pressed and squeezed from the surface side by the contact edge of the pressing member, and the label is peeled off by folding the front end portion. In this case, since the ironing force of the pressing member is adjusted by the ironing force adjusting means, it matches the degree of the adhesive force of the adhesive provided on the label or the conditions such as the thickness and shape of the belt-like mount or label. Thus, the squeezing force can be set, so that the squeezing force can be set appropriately and the label can be peeled off reliably.

And, if necessary, the pressing member extends in a direction perpendicular to the feeding front-rear direction along the support surface of the belt-like mount, and faces the upstream opening edge and the downstream opening edge of the groove and is placed on the surface of the belt-like mount. It is configured with a straight contact edge that contacts,
The pressing force adjusting means is arranged so that the abutting edge of the pressing member is movable between the upstream opening edge and the downstream opening edge of the groove in the front-rear direction of feeding along the support surface of the belt-like mount. A support mechanism for supporting the member and a lock mechanism for positioning the pressing member at a required movement position are provided.

  Thus, the ironing force can be adjusted by releasing the lock mechanism, moving the contact edge of the pressing member between the upstream opening edge and the downstream opening edge of the groove, positioning it at a required position, and again using the lock mechanism. Lock and do. In this case, by making the position of the abutting edge of the pressing member close to or away from the upstream opening edge or the downstream opening edge, it is possible to change the bending state of the belt-like mount and adjust the squeezing force of the label. For this reason, the ironing force can be adjusted simply by moving the contact edge of the pressing member in the front-rear direction of feeding along the support surface of the belt-like mount, and the adjustment can be easily performed.

  Further, if necessary, the groove is formed in a substantially rectangular cross-sectional shape having a bottom surface, an upstream side wall surface, and a downstream side wall surface so that the upstream opening edge and the downstream opening edge form corners. It is said. As a result, the upstream opening edge and the downstream opening edge of the groove form corners, and the abutting edge of the pressing member is straight, so the label is formed by the corner and the straight abutting edge. Compared to the conventional method of squeezing against a circular arc surface, it will be squeezed at three corners, so that the ironing will be performed sufficiently and the label will be peeled off. Is surely done.

  Further, if necessary, the pressing member is provided with a biasing mechanism for biasing the pressing member toward the groove so that the contact edge of the pressing member elastically contacts the belt-like mount. Thereby, since the contact edge of the pressing member is elastically contacted with the belt-like mount by the urging mechanism, it is possible to follow this even when the thickness of the belt-like mount or the label is different, so that the ironing is sufficiently performed. At the same time, it is possible to prevent a situation such that the passage of the belt-like mount becomes tight and damages the surface of the label.

Furthermore, if necessary, the holding member has an axis in a direction orthogonal to the feeding front-rear direction along the supporting surface of the strip-shaped mount and a supporting plate provided on a side portion of the peeling member. And a support shaft that is movable with respect to the support plate in the front-rear direction of feeding along the support surface of the belt-like mount. The biasing mechanism is configured to be movable, and is configured by a coil spring that is inserted into the support shaft, one end is locked to the support shaft, and the other end is locked to the pressing member.
As a result, the pressing member can be pivotably provided on the support shaft, and the contact edge of the pressing member can be elastically contacted with the label by the biasing force of the coil spring, so that the apparatus is configured with a relatively simple structure. Can do.

If necessary, the pressing member is pressed by the urging mechanism to press the abutting edge of the pressing member against the bottom surface of the groove, and the abutting edge of the pressing member is a support surface of the peeling member. Retreating upward and enabling movement to two positions, a retreat position that forms a space for allowing the band-shaped mount to pass between the pressing member and the supporting surface of the peeling member, and the pressing member is moved to the pressing position and the retreating position. The positioning mechanism for positioning at the two positions is provided.
Thus, when the belt-like mount is mounted on the apparatus, the pressing member is positioned at the retracted position. In this case, at the retracted position, a space for allowing the belt-like mount to pass is formed between the pressing member and the support surface of the peeling member, so that the belt-like mount can be easily passed through, thereby improving the mounting operability. be able to. On the other hand, when the strip-shaped mount is fed and the label is peeled off, the pressing member is positioned at the pressing position. Thereby, the peeling operation similar to the above can be performed.

  According to the present invention, the squeezing force of the pressing member can be adjusted by the squeezing force adjusting means. In addition, since the squeezing force can be set, the squeezing force can be set appropriately and the label can be peeled reliably.

It is a figure which shows an example of the conventional label peeling apparatus.

Hereinafter, a label peeling device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIGS. 1 to 7, the label peeling apparatus S according to the embodiment of the present invention can take out the label L by hand and attach the label L to an article not shown which is an adherend. The belt-like mount D on which a plurality of labels L are temporarily attached along the longitudinal direction is sent from the supply reel 3 along the longitudinal direction by the mount feeding mechanism 2 provided on the machine base 1. The label L is peeled off from the belt-like mount D by winding it with the take-up reel 4 and turning back the belt-like mount D in this sending process. The machine base 1 has a support surface 11 that supports the back surface Db of the belt-like mount D with the front surface Da on which the label L of the belt-like mount D delivered from the supply reel 3 is temporarily attached, and a front end of the belt-like mount D that is folded back. A peeling member 10 having a portion 12 is provided.

  A label sensor 5 that detects the presence or absence of a label L protruding a predetermined length from the distal end portion 12 of the peeling member 10 is provided on the downstream side of the distal end portion 12 of the peeling member 10. When the label sensor 5 detects the label, the feeding of the belt-like mount D is temporarily stopped. In this state, the label L protrudes from the front end portion 12 of the peeling member 10 by a predetermined length. Is possible. After the label L is taken out, the label sensor 5 detects that there is no label, and again sends out the belt-like mount D, causing the next label L to protrude from the front end portion 12 of the peeling member 10.

  In the peeling member 10, a groove 15 extending in a direction perpendicular to the feeding front-rear direction R along the support surface 11 of the belt-like mount D is inserted in the vicinity of the front end portion 12 of the support surface 11 and into which the belt-like mount D on the support surface 11 is immersed. Is formed. As shown in FIGS. 2, 6 and 7, the groove 15 of the peeling member 10 has a bottom surface 16, an upstream side wall surface 17, and an upstream opening edge 17 a and a downstream opening edge 18 a so as to form corners. The downstream side wall surface 18 is formed in a substantially rectangular cross section.

Further, the machine base 1 is provided with a pressing member 20 that presses the belt-like mount D against the groove 15 from the surface side. The label L temporarily attached to the belt-like mount D by the groove 15 and the pressing member 20 is attached. I try to peel it off.
Specifically, as shown in FIG. 2, the pressing member 20 is composed of a plate-shaped distal end side portion 21 and a box-shaped proximal end side portion 22 connected to the plate-shaped distal end side portion 21. The leading edge extends in a direction perpendicular to the sending back and forth direction R along the support surface 11 of the belt-like mount D, faces the upstream side wall surface 17 and the downstream side wall surface 18 of the groove 15, and contacts the surface of the belt-like mount D. A contact edge 23 is formed. The pressing member 20 is urged toward the bottom surface 16 of the groove 15 by an urging mechanism 30 described later so that the abutting edge 23 of the pressing member 20 elastically contacts the belt-like mount D and presses the belt-like mount D. Further, the pressing member 20 is configured such that the abutting edge 23 of the pressing member 20 is movable between the upstream side wall surface 17 and the downstream side wall surface 18 of the groove 15 in the forward / backward direction R along the support surface 11 of the belt-like mount D. It is supported.

Further, the pressing member 20 can move to the support surface 11 side upstream of the groove 15 so that the contact edge 23 of the pressing member 20 presses the belt-like mount D on the support surface 11 upstream of the groove 15. It is supported to become. The pressing member 20 has a function of simply pressing the supporting surface 11 of the peeling member 10 without the contact edge 23 of the pressing member 20 being detached from the groove 15 and squeezing the label L together with the groove 15.
That is, the pressing member 20 can move from the squeezing position F where the belt-like mount D is pressed against the groove 15 from the surface side to the non-scoring position G where the belt 15 is not squeezed with the groove 15. It is supported.

  Further, the apparatus S includes an ironing force adjusting means T that adjusts the ironing force by the pressing member 20 at the ironing position F of the pressing member 20. In the squeezing force adjusting means T, the abutting edge 23 of the pressing member 20 is movable between the upstream opening edge 17a and the downstream opening edge 18a of the groove 15 in the front-rear direction R along the support surface 11 of the belt-like mount D. Thus, the support mechanism Ta that supports the pressing member 20 and the lock mechanism Tb that positions the pressing member 20 at a required movement position are configured. The support mechanism Ta has a function of supporting the pressing member 20 so as to be movable between the ironing position F and the non-ironing position G. The lock mechanism Ta requires the pressing member 20 even in the non-ironing position G. A function of positioning at the moving position is provided.

  Specifically, the support mechanism Ta has a support plate 24 provided on the side portion of the peeling member 10 and an axis in a direction perpendicular to the sending back and forth direction R along the support surface 11 of the belt-like mount D. And a support shaft 25 provided to be movable in the front-rear direction R along the support surface 11 of the belt-like mount D with respect to the support plate 24. One end of the support shaft 25 is provided on the peeling member 10 side of the support plate 24, and is attached to a moving member 26 that can slide in the front-rear direction R along the support surface 11 of the belt-like mount D. The support shaft 25 is The movable member 26 can be moved. And the base end side part 22 of the pressing member 20 is supported by this support shaft 25 so that rotation is possible. As shown in FIGS. 3 and 5, the insertion hole 27 to the support shaft 25 formed on the base end side portion 22 has an inner diameter slightly larger than the outer diameter of the support shaft 25, and thereby the pressing member 20 is supported so as to be rotatable and slightly movable with respect to the support shaft 25.

  The label peeling device S according to the embodiment includes a biasing mechanism 30 that biases the pressing member 20 toward the bottom surface 16 side of the groove 15 so that the contact edge 23 of the pressing member 20 comes into elastic contact with the belt-like mount D. It has been. As shown in FIGS. 3 and 5, the biasing mechanism 30 includes a coil spring 31 that is inserted into the support shaft 25, one end is locked to the support shaft 25, and the other end is locked to the pressing member 20. Yes. Since the urging mechanism 30 is provided on the support shaft 25 so as to be rotatable, the urging force of the coil spring 31 can elastically contact the contact edge 23 of the urging member 20 with the label L. This makes it possible to configure the apparatus.

  Further, as shown in FIG. 3, the lock mechanism Tb is provided on the support plate 24 and on the peeling member 10 side of the support plate 24 and the long hole 41 extending in the front-rear direction R along the support surface 11 of the belt-like mount D. The moving member 26 that supports one end of the support shaft 25 and is slidable along the long hole 41, a female screw portion 42 formed at a position corresponding to the long hole 41 of the moving member 26, and a support plate The bolt head 43a located on the opposite side to the peeling member 10 of 24 and the bolt 43 having the male screw portion 43b screwed into the female screw portion 42 provided in the moving member 26 through the long hole 41 are configured. Yes.

  The lock mechanism Tb clamps the support plate 24 with the bolt head 43a of the bolt 43 and the moving member 26 by tightening the male screw portion 43b of the bolt 43 to the female screw portion 42, and moves the moving member 26 to the required movement. Position by position. When the male screw portion 43 b of the bolt 43 is loosened with respect to the female screw portion 42, the lock is released, and the pressing member 20 can be moved via the support shaft 25 and the moving member 26. Since the lock mechanism Tb can move the moving member 26 with respect to the long hole 41 and can be locked by the tightening operation of the bolt 43, the apparatus can be configured with a relatively simple structure.

  Further, as described above, the pressing member 20 is supported so as to be rotatable and slightly movable with respect to the support shaft 25 through the insertion hole 27, whereby the pressing member 20 is supported by the urging mechanism. The pressing position X (FIG. 1, FIG. 2, FIG. 5 (b), FIG. 6 and FIG. 7) for pressing the contact edge 23 against the bottom face 16 side of the groove 15 by the coil spring 31 of 30, and the biasing mechanism 30 The pressing member 20 is rotated relative to the support shaft 25 against the urging force of the coil spring 31, and the contact edge 23 is retracted above the support surface 11 of the peeling member 10, so that the pressing member 20 and the peeling member 10 It is movable to two positions, a retreat position Y (FIG. 5A) that forms a space for allowing the belt-like mount D to pass between the support surface 11. A plate-like lever 28 for rotating the pressing member 20 from the pressing position X to the retracted position Y against the urging force of the coil spring 31 is provided on the proximal end side portion 22 of the pressing member 20. .

  And in the label peeling apparatus S which concerns on embodiment, as shown in FIG.4 and FIG.5, the positioning mechanism 50 which positions the pressing member 20 in two positions, the pressing position X and the retracted position Y, is provided. . The positioning mechanism 50 includes a locking pin 51 protruding from the moving member 26 and a cam groove 52 provided on the proximal end side of the pressing member 20 and through which the locking pin 51 is inserted. The cam groove 52 is guided by the locking pin 51 to enable the urging force of the coil spring 31 and the holding member 20 to rotate against the support shaft 25 against the urging force of the coil spring 31. The locking step portion 54 is formed so as to be locked to the locking pin 51 by the movement of the pressing member 20 with respect to the support shaft 25 and to hold the pressing member 20 in the retracted position Y when moved. Since the positioning mechanism 50 is configured by the locking pin 51 and the cam groove 52, the pressing member 20 can be positioned at two positions of the pressing position X and the retracted position Y only by the rotation operation of the pressing member 20. Therefore, the operability can be improved, and the apparatus can be configured with a relatively simple structure.

  Therefore, in this label peeling apparatus S, when the belt-like mount D is attached to the apparatus, the belt-like mount D is pulled out from the supply reel 3 and attached to the take-up reel 4 via the peeling member 10. 5 positions the pressing member 20 at the retracted position Y as shown in FIG. In this case, the lever 28 of the pressing member 20 is lifted by hand, and the pressing member 20 is rotated from the pressing position X to the retracted position Y against the urging force of the coil spring 31. At the retracted position Y, the locking step 54 of the cam groove 52 of the positioning mechanism 50 is locked to the locking pin 51, and the pressing member 20 is held at the retracted position Y. Accordingly, a space for allowing the belt-like mount D to pass between the pressing member 20 and the support surface 11 of the peeling member 10 is formed, so that the belt-like mount D can be easily passed through. Operability can be improved. After that, when the lever 28 of the pressing member 20 is pressed, the pressing member 20 can move freely with respect to the support shaft 25, so that the locking step portion 54 of the cam groove 52 is disengaged from the locking pin 51 due to this movement. Is rotated from the retracted position Y to the pressing position X by the urging force of the coil spring 31.

When ironing the belt-like mount D, the pressing member 20 is moved to the ironing position F, and the pressing member 20 is positioned at a required position by the ironing force adjusting mechanism T as will be described later. deep. In this state, as shown in FIG. 3 and FIG. 6, the pressing member 20 requires the contact edge 23 of the pressing member 20 between the upstream opening edge 17 a and the downstream opening edge 18 a of the groove 15 by the lock mechanism Tb. Is positioned and locked at the position (for example, FIG. 6A). When the label peeling device S is operated, the belt-like mount D is sent out from the supply reel 3, and the belt-like mount D has the front surface Da on which the label L is temporarily attached facing upward so that the back surface Db supports the peeling member 10. It is supported by the surface 11 and is folded at the front end portion 12 of the peeling member 10. In the vicinity of the front end portion 12, the belt-like mount D is immersed in the groove 15 having a substantially rectangular cross section and is pressed from the surface side by the contact edge 23 of the pressing member 20.
In this case, since the abutting edge 23 of the pressing member 20 is elastically contacted with the belt-like mount D by the biasing mechanism 30, it is possible to follow this even when the thickness of the belt-like mount D or the label L is different. While the ironing is sufficiently performed, it is possible to prevent a situation in which the passage of the belt-like mount D is cramped and the surface of the label L is damaged.

  Further, as shown in FIG. 6, the belt-like mount D contacts the upstream opening edge 17a and the downstream opening edge 18a of the groove 15 on the back surface Db side, and the upstream opening edge 17a on the surface Da side. And the contact edge 23 of the pressing member 20 between the downstream opening edges 18a. In this case, since the upstream opening edge 17a and the downstream opening edge 18a form a corner, and the contact edge 23 of the pressing member 20 is straight, the label L is in direct contact with this corner. Since it will be squeezed by the edge 23, it will be squeezed at three corners as compared with the case where it is squeezed in contact with the arc surface as in the conventional case. Fully performed, the label L is peeled off reliably.

  When the label L is peeled from the belt-like mount D and the label sensor 5 on the downstream side of the front end portion 12 of the peeling member 10 detects the label L, the feeding of the belt-like mount D is temporarily stopped. In this state, the label L protrudes from the tip end portion 12 of the peeling member 10 by a predetermined length. Therefore, the label L is taken out by hand, and the label L is affixed to the article as an adherend. In this case, if the label L to be peeled is released away from the pressing member 20, it becomes easy to take out the label L. However, since the label L may fall, the upstream side of the label L to be peeled off The end portion can also be pressed by the pressing member 20. After the label L is taken out, the label sensor 5 detects that there is no label, and again sends out the belt-like mount D, causing the next label L to protrude from the front end portion 12 of the peeling member 10. In this way, the label L is peeled sequentially.

  Next, for example, a case where the ironing force is adjusted by the ironing force adjusting mechanism T when the state and type of the belt-like mount D and the label L are different will be described. In this case, it is performed as follows. As shown in FIG. 3, first, the male screw portion 43b of the bolt 43 of the lock mechanism Tb is loosened with respect to the female screw portion 42 to release the lock. In this state, the contact edge 23 of the pressing member 20 is moved between the upstream side wall surface 17 and the downstream side wall surface 18 of the groove 15 as shown in FIGS. After positioning, as shown in FIG. 3, the male screw portion 43 b of the bolt 43 of the lock mechanism Tb is fastened and locked to the female screw portion 42. As a result, the position of the contact edge 23 of the pressing member 20 is moved closer to or away from the upstream opening edge 17a or the downstream opening edge 18a, thereby changing the bending state of the belt-like mount D and adjusting the squeezing force of the label L. can do. For this reason, it is possible to set the squeezing force according to the degree of adhesive strength of the adhesive provided on the label L, or according to the conditions such as the thickness and shape of the belt-like mount D and the label L. Thus, the label L can be peeled off reliably.

  By the way, in the belt-like mount D, the adhesive force of the label L is relatively weak, and there are some which do not require ironing. Alternatively, there are some that do not require ironing depending on the shape and material of the label L. Moreover, if the length of the label L in the longitudinal direction is relatively long and the downstream side of the label L protrudes too far from the tip end portion 12 of the peeling member 10, it may hang down and become difficult to take out. In that case, although it is desired to take a long portion remaining on the belt-like mount D, the pressing member 20 obstructs the removal of the label L. In some cases, the label L may be removed so that the surface of the label L is exposed as much as possible so that it can be seen clearly. The label peeling apparatus S according to the present embodiment can cope with such a label L. In this case, the pressing member 20 is moved from the ironing position F to the non-ironing position G as follows.

  First, as shown in FIG. 3, the male screw portion 43b of the bolt 43 of the lock mechanism Tb is loosened with respect to the female screw portion 42 to release the lock. In this state, as shown in FIG. 2 and FIG. 7, the pressing member 20 is formed so that the contact edge 23 of the pressing member 20 presses the belt-like mount D on the support surface 11 on the upstream side of the groove 15. 3 is moved to the non-ironing position G on the upstream side of the support surface 11 and positioned at an appropriate position. As shown in FIG. 3 again, the male screw portion 43b of the bolt 43 of the lock mechanism Tb is changed to the female screw portion. Tighten to 42 and lock. As a result, as shown in FIG. 7, the contact edge 23 of the pressing member 20 is removed from the groove 15, and the label L is simply moved against the support surface 11 of the peeling member 10 without cooperating with the groove 15. I will hold it down. For this reason, it is possible to cope with a label L that has a relatively weak adhesive force and does not require ironing, or that does not require ironing due to the shape or material of the label L. Also, when the length of the label L in the longitudinal direction is comparatively long and it is desired to take a long portion remaining on the belt-like mount D, or when the surface of the label L is exposed as much as possible so that the label L can be seen and taken out. However, since the pressing member 20 moves to the upstream side, it does not obstruct the taking-out of the label L because it gets in the way, so it can be dealt with. In this case, since the contact edge 23 of the pressing member 20 is formed in a straight shape, the pressing can be ensured.

  In the above embodiment, the shape of the groove 15 and the shape of the pressing member 20 are not limited to the shapes described above, and may be appropriately changed.
