[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a delivery reel for a long sheet, which is used by stacking the long sheets in a multi-tiered manner, and in particular, an upper long sheet and a lower long sheet adjacent to the upper long sheet. The present invention relates to a long-sheet feeding reel that is suitable for continuous feeding when connected to each other.

[0002]

2. Description of the Related Art A cylindrical label or the like such as a shrink label attached to a container or the like is a long strip-shaped label forming base material which is folded into a sheet in a state where a large number of labels are connected to each other in a labeling device. It is generally mounted on a container or the like while forming individual labels by cutting, and such a long sheet-shaped label forming substrate is usually wound around a paper tube in a roll shape. Set the item (hereinafter referred to as sheet roll) on the feeding device of the labeling device,
Used while continuously feeding.

By the way, since the length of the label-forming substrate that can be wound into a roll is naturally limited, the sheet roll set in the labeling device must be frequently replaced, and the labeling device must be replaced. It cannot be operated efficiently.

Therefore, conventionally, the sheet rolls are mounted on the reels, the reels are stacked in multiple stages, and the sheet rolls mounted on the upper reels and the sheet rolls mounted on the lower reels are connected to each other. By continuously feeding the label forming substrate from the plurality of reels, the number of times the sheet roll is replaced is reduced and the labeling device is operated efficiently.

Usually, such a reel has a cylindrical core member 51 into which a sheet roll is fitted, as shown in FIG.
And the collar member 52 which is detachably attached to one end of the core member 51, so that the reels 50 are stacked in multiple stages and the label forming substrate is continuously fed out, as described above. In order to make the core member 5 of the reel 50, the inner end portion (winding start portion) of the sheet roll from which the paper core is removed is pulled out from the sheet roll.
1 and stacking the plurality of reels 50 with the sheet rolls mounted in this way, as shown in FIG.
The outer end (winding end portion) or the pulled-out inner end (winding start portion) of the sheet roll R mounted on the upper reel 50 and the sheet roll R mounted on the adjacent lower reel 50. By connecting the pulled-out inner end (winding start portion) or the outer end (winding end portion), the sheet rolls R mounted on the plurality of reels 50 are connected to each other.

[0006]

By the way, as described above, when the sheet rolls R mounted on the reels 50 stacked in multiple stages are connected to each other, the sheet rolls R are first pulled out from the inside of the sheet roll R. The winding start portion is held at a predetermined position in a state of being sandwiched between the upper or lower surface of the sheet roll R and the collar member 52. As shown in FIG. 8, a label forming base material is used. Inside, reel 5
Since the diameter of the sheet roll R attached to 0 becomes gradually smaller, the winding start portion pulled out from the inside of the sheet roll R in order to connect to the sheet roll R attached to the adjacent reel 50, that is, The connecting portion Rc of the adjacent reel 50 with the sheet roll R gradually becomes free.

Therefore, as described above, the upper reel 5
The connection portion Rc between the sheet rolls R, which are in a free state during use, is repeatedly formed by simply connecting the sheet roll mounted on the reel 0 and the sheet roll mounted on the lower reel 50. The reel 50 adjacent to the reel 50 on which the label forming base material is fed out is gradually displaced due to the rotation operation and the stop operation of the reel 50.
There is a problem that the wound state of the sheet roll R mounted on the sheet is gradually loosened and collapses, so that the sheet roll R eventually falls outside the flange member 52, which makes subsequent use difficult. Especially for high-speed labeling equipment,
Since the rotation speed of the reel 50 also increases, the tendency becomes remarkable.

SUMMARY OF THE INVENTION An object of the present invention is to provide a feeding reel for a long sheet which does not collapse even when it is stacked in multiple stages and continuously fed.

[0009]

In order to solve the above-mentioned problems, the present invention relates to a long-sheet feeding reel for stacking and using multi-stage long sheets in a wound state, A core member for mounting a sheet roll in which a long sheet is directly wound or a long sheet is wound in advance in a roll shape, and a disc-shaped flange member attached to at least one end of the core member, and the flange member is provided. Is extended radially outward from the peripheral edge and connects the winding end portion or winding start portion of the upper long sheet and the winding start portion or winding end portion of the adjacent lower long sheet to each other. In addition, the present invention provides a long sheet feeding reel to which a stopper member for locking the connecting portion in the circumferential direction of the collar member is attached. The term "long sheet" used herein means a long strip-shaped film or sheet formed of various materials such as synthetic resin, paper, and metal.
Alternatively, it is a wide concept including a tube folded in a flat state.

In the long sheet feeding reel configured as described above, in the state of being stacked in multiple stages, the long sheet mounted on the upper feeding reel as a winding or sheet roll and the adjacent lower feeding reel. When a long sheet mounted as a roll or a sheet roll is connected to each other and the connecting portion is hooked on the stopper member, the connecting portion of the long sheet is moved in the circumferential direction of the flange member by the stopper member. Since the positioning is performed to some extent, even if the diameter of the roll-shaped long sheet wound or mounted on the delivery reel is reduced, the connecting portion is less likely to be displaced due to the rotation and stop operation of the reel. As a result, the winding state of the roll-shaped long sheet wound around the feeding reel adjacent to the feeding reel in which the long sheet is fed or mounted as a sheet roll is loosened and may fall off beyond the flange member. Instead, the long sheet can be smoothly delivered from the uppermost stage to the lowermost stage.

When the stopper member is movably attached along the peripheral edge of the flange member as in the delivery reel according to the second aspect of the present invention, the long reel mounted on the upper delivery reel as a winding or a sheet roll. After connecting the length sheet and the long sheet mounted as a sheet roll or a sheet roll on an adjacent lower feeding reel to each other, by moving the stopper member so as to abut the connection portion, at all times,
There is an effect that the connection portion of the long sheet can be held in a predetermined tension state, and even if the connection position deviates in the circumferential direction of the collar member, it is possible to easily cope with it.

Further, as in the third aspect of the present invention, the stopper member is provided with a long sheet hooking portion inclined by 35 to 75 degrees with respect to the tangential direction of the outer peripheral surface of the collar member. In this case, the connection part of the long sheet that is hooked does not easily fall off and is held in a state that it is not deformed by distortion, so the connection part of the long sheet can be reliably protected from damage. The effect is that it can be hung.

When the plurality of delivery reels 1 are stacked in multiple stages so as to be fitted in the la 1a, the stacked delivery reels 1 are integrated in a state in which they are mutually prevented from rotating.

The collar member 20 has a structure shown in FIGS.
In addition to the holes 20b described above, the core member 10
The center hole 20a is formed corresponding to the center hole 10a of the ring groove 2.
1 is formed, and the stopper member 30 is movably supported in the circumferential direction by the annular groove 21. The support structure of the stopper member 30 will be described in detail later.

The stopper member 30 is shown in FIGS.
As shown in FIG. 2, in the state where a plurality of feeding reels 1 are stacked in multiple stages, the winding start portion or the winding start portion of the lower feeding reel 1 that is adjacent to the winding end portion or the winding start portion of the long sheet of the upper feeding reel 1 Alternatively, when the winding end portion is connected to each other, a main body portion 31 that hooks the connection portion in the circumferential direction of the collar member 20, and the main body portion 31 movably along the peripheral edge of the collar member 20. The support plate 32 is attached to the member 20.

As shown in FIGS. 3 (a) and 3 (b), the main body 31 is formed of a metal plate in the shape of an isosceles right triangle which is slightly thicker than the wall thickness of the collar member 20, and its upper surface. A recess 31a into which a support plate 32 to be described later is fitted is formed on the lower surface and the lower surface, and a screw hole 31b for fixing the support plate 32 is formed in a region where the recess 31a is formed.
Are formed so as to penetrate vertically.

Further, the main body 31 is formed in an arc shape having the same radius of curvature as that of the collar member 20 so that a portion 31c corresponding to the base of the substantially right-angled isosceles triangle is along the outer peripheral surface of the collar member 20. In addition, since the upper and lower corner portions 31d of the portion corresponding to the hypotenuse of the substantially right-angled isosceles triangle are the portions with which the long sheet comes into contact, the round sheet should be rounded so as not to damage the long sheet that comes into contact. There is.

As shown in FIGS. 4 (a) and 4 (b), the support plate 32 is formed of a thin metal plate whose tip portion is formed in a substantially right-angled isosceles triangle shape, and the tip is substantially right-angled. A screw insertion hole 32a is formed in the isosceles triangle portion so as to correspond to the screw hole 31b of the main body 31. Therefore, as shown in FIGS. 5 (a) and 5 (b), the main body 31 is moved up and down by fitting the tips of the isosceles right triangles into the upper and lower recesses 31a of the main body 31 and screwing. The pair of support plates 32 are fixed in a state of being sandwiched between them. In this state, the rear end portion of the support plate 32 projects rearward from the main body portion 31.

Further, a tongue piece 32c is formed at the rear end portion of the support plate 32 by a U-shaped cut 32b, and the tip end of the tongue piece 32c is attached to the main body portion 31. The tongue piece 32c is bent so as to slightly project to the inner surface side of 32. Bent portion 3 of this tongue piece 32c
2d is, as shown in FIG. 5 (b), the collar member 20 described above.
It is adapted to be fitted in the annular grooves 21 formed on both front and back surfaces, and the bent portion 32d of the tongue piece 32c is fitted in the annular groove 21, whereby the main body portion 31 is positioned in the radial direction of the collar member 20. In addition, the main body 31 is supported by the flange member 20 in a state in which the main body 31 can move along the annular groove 21 on the outer periphery of the flange member 20.

When the long sheet feeding reel 1 configured as described above is used to continuously feed the long sheet from the plurality of feeding reels 1, first, the long sheet such as the label forming substrate is cored. A core member 1 in which a long sheet is wound after forming a sheet roll by directly winding the member 10 around the member 10.
0 of the core of the feeding reel 1 in which the collar member 20 is attached, or the paper tube is removed from the sheet roll in which a long sheet is wound in advance, and the sheet roll is attached. Attach to the member 10. In addition,
As described above, when the long sheet is started to be wound around the core member 10, or the sheet roll with the paper tube removed is used as the core member 1.
When mounted on 0, the winding start portion of the long sheet located inside the sheet roll needs to be pulled out from the sheet roll by a predetermined length in advance. Alternatively, the core member 10 may be attached to the inside of the sheet roll after the sheet roll from which the paper tube has been removed is placed on the collar member 20.

In this way, the plurality of feeding reels 1 with the sheet rolls mounted thereon are sequentially stacked as shown in FIG. 2 (FIG. 2 shows a state in which the sheet rolls are not mounted), and sheets. The winding start portion of the long sheet previously drawn from the inside of the roll and the winding end portion of the long sheet positioned outside the sheet roll mounted on the adjacent lower feeding reel 1 are connected to each other. To do.
At this time, if the stopper member 30 attached to the collar member 20 is slid in the circumferential direction of the collar member 20 to be retracted to a position apart from the connecting portion of the long sheet, the stopper member 30 will be damaged. Therefore, the work of connecting long sheets can be smoothly performed.

When the connection between the sheet rolls of the upper and lower feeding reels 1 adjacent to each other is completed, the stopper member 30 is slid in the circumferential direction of the collar member 20 to move it to the connecting portion of the long sheet, and FIG. As shown in FIG. 6, the stopper member 30 is pressed against the connection portion Rc of the long sheet to such an extent that a predetermined tension is applied to the connection portion Rc of the long sheet, so that the connection portion Rc of the long sheet is stopped. Hook on the member 30.

When the feeding reels 1 stacked in multiple stages in such a state are set in a labeling device or the like and used, as shown in FIG. 6, a long sheet is fed out so that the diameter of the sheet roll R is reduced. Even when it becomes small, the connecting portion Rc of the long sheet that is pulled out from the inside of the sheet roll R and is connected to the winding end portion of the sheet roll R of the lower supply reel 1 does not become a free state, Since the member 30 is always kept in a predetermined tension state, the winding state of the sheet roll R of the lower delivery reel 1 adjacent to the delivery reel 1 from which the long sheet is delivered is loosened and collapsed. The long sheet can be smoothly delivered from the uppermost delivery reel to the lowermost delivery reel without raising.

In this embodiment, the stopper member 30 having an approximately right-angled isosceles triangle shape is attached so as to project from the outer peripheral surface of the collar member 20, so that the hooking portion of the connection portion Rc of the long sheet is the collar portion. Although it projects to the outside of the collar member 20 in a state of being inclined about 45 degrees with respect to the tangential direction of the outer peripheral surface of the member 20, the projection angle of the hooking portion is not limited to 45 degrees and is 35 to 75 degrees. It may be set appropriately within the range. When the overhang angle of the hooking part becomes smaller than 35 degrees,
This is because the connecting portion Rc of the long sheet is likely to fall off the stopper member 30, and when the projecting angle of the hooking portion becomes 75 degrees or more, the connecting portion Rc of the long sheet is deformed into strain. This is because the connecting portion Rc of the long sheet is easily damaged.

As described above, in this embodiment, the stopper member 30 is formed into a substantially right-angled isosceles triangle, but if the hooking portion having the bulging angle within the above-mentioned range is provided, the whole shape is particularly preferable. Can be anything.

Further, in this embodiment, the stopper member 3
Although 0 is attached so as to be movable in the circumferential direction of the collar member 20, it is not necessarily required to be movable. However, when the stopper member 30 is movably attached to the collar member 20, the position of the connecting portion Rc of the long sheet is located at the collar member 20.
Even if the sheet is displaced in the circumferential direction, the connection position Rc of the long sheet can be easily adjusted.
Since there is no need to align with the attachment position of, the effect is that the connection work of long sheets can be performed efficiently.

Further, in this embodiment, the flange member 20 is attached to only one end surface of the core member 10, but it is also possible to attach the flange member 20 to both end surfaces of the core member 10. In that case, needless to say, the stopper member 30 may be attached to either one of the collar members 20.
