Description

TECHNICAL FIELD The present invention relates to a take-up roller for taking up a belt-shaped body such as a label backing sheet from which a label has been peeled.

A take-up device comprising a delivery roller for feeding a label base material consisting of a label and a label backing sheet to the downstream side, an affixing mechanism for affixing the label to an object to be labeled, and a take-up roller for winding up the label backing sheet from which the label has been peeled off. Labeling machines with rollers are known.

Since a tensile force acts on the label backing sheet wound up by the winding roller of such a labeling apparatus, it is tightly wound around the winding roller. Therefore, there is a problem that it becomes difficult to remove the wound label mount from the winding roller.

In order to solve such a problem, conventionally, a pair of cutout grooves into which both ends of the U-shaped pin are inserted are formed in the outer peripheral surface of the winding bobbin along the axial direction of the winding bobbin. the notch groove at the base end of the winding bobbin is shallower than the notch groove at the tip of the winding bobbin; It is composed of a straight portion that engages with the notched groove and a connecting portion that connects the base ends of the straight portions, and the connecting portion is bent with respect to both straight portions and connected to the base ends of the straight portions. is known to form a stepped portion that rides on the tip of the winding bobbin in a state where the tip of both straight portions rides on the base of the winding bobbin (see, for example, Patent Document 1). . According to this configuration, since the wound label mount can be loosened by removing the U-shaped pin, the label mount can be easily pulled out.

Further, a winding roller for winding a belt-shaped release liner, which is formed in a columnar shape and has a roller main body in which a groove portion extending in the axial direction is formed on the outer peripheral surface, and a roller body formed in a bar shape and having the groove portion extending in the longitudinal direction. It can be inserted into the groove so as to match the extending direction and partly protrude from the outer peripheral surface, and the axis extending in the longitudinal direction while being inserted into the groove and a rotation restricting means for restricting rotation of the gripping portion with respect to the groove when the gripping portion is inserted into the groove, wherein the gripping portion is in contact with the groove. It has a sandwiching portion that sandwiches the release liner therebetween, and the sandwiching portion has a dimension in a first direction perpendicular to the axial direction in a cross section perpendicular to the axial direction of the sandwiching portion. The pinching portion is formed in a shape longer than the dimension in the second direction perpendicular to the direction, and protrudes from the outer peripheral surface of the roller body in a state in which the first direction of the pinching portion is oriented in the radial direction of the roller body. The length of the part is longer than the length of the pinching part protruding from the outer peripheral surface of the roller body in a state in which the second direction of the pinching part is oriented in the radial direction of the roller body, and the rotation restricting means It is known to regulate the rotation of the pinching portion with respect to the groove portion so as to maintain the first direction of the pinching portion facing the radial direction of the roller body (see, for example, Patent Document 2). .).

JP-A-3-18543 Japanese Patent No. 6418494

In the case of the configuration described in Patent Document 1, the pressure of the rolled-up label mount is applied to the U-shaped pin, so there is a problem that a strong force is required to pull out the U-shaped pin. Moreover, there is a problem that the pulled out pin may be lost.

The clamping part of Patent Document 2 is cylindrical and rotates about the center of the clamping part in the groove. In order to maintain the posture of the columnar holding portion without any particular catching or the like, only the rotation restricting means functions in a state in which the first direction, which receives strong pressure from the rolled-up release liner, is oriented in the radial direction. It is clear that it requires support from the walls of the groove, rather than being supported by the wall of the groove. Therefore, the dimension of the nipping portion is such that the bottom and side surfaces of the nipping portion are sufficiently supported by the groove while the first direction is oriented radially, and the dimension in the second direction is approximately the same as the width of the groove. It must be formed to size. Further, when the second direction is oriented radially, if the dimension in the first direction greatly exceeds the width of the groove, the end in the first direction is caught by the edge of the groove, resulting in the pinched portion. Rotation may become difficult, or the first direction of the pinching part may not fit in the groove, and the pinching part may be in a state of being largely lifted from the groove. should be formed to For this reason, in the case of the configuration described in Patent Document 2, the difference between the first direction dimension and the second direction dimension of the pinching portion cannot be increased, and the wound peeling liner does not flex. There is a problem that the size becomes smaller and the difficulty of pulling out the release liner cannot be completely resolved.

The take-up roller 1 according to the present embodiment is provided in a labeling device (not shown) that sequentially affixes labels to product packaging containers, cardboard boxes, and the like. The label application device feeds the label base material, which is printed with product information and delivery address, continuously in the longitudinal direction on the label backing paper, to the downstream side by the feeding roller, and attaches it to the product packaging container or cardboard. This is a device that sequentially affixes labels peeled from the label backing paper by a mechanism.

The take-up roller 1 is rotatably supported in the peripheral direction by a label application apparatus main body (not shown) via a shaft 2 . The rotation of the take-up roller 1 is performed by a drive mechanism provided in the main body of the label application apparatus, and the direction and speed of rotation can be changed by operating the drive mechanism. It rotates and rolls up and collects the label backing sheet (hereinafter referred to as a belt-like body) from which the label has been peeled off.

The take-up roller 1 is formed of a roller body 5 having a groove portion 4 extending in the axial direction on the outer peripheral surface of a cylindrical portion 3 and a rectangular plate-like body. Along the direction, one long side 6a protrudes outside from the groove 4, the other long side 6b is positioned in the groove 4, and is rotatably supported in the groove 4 with the other long side 6b as a fulcrum. A belt-shaped body receiving portion 6 is provided.

The belt-shaped object receiving portion 6 has rod-shaped shaft portions 7 along the axial direction of the roller main body 5 at both ends on the other long side 6b side. The portions 5a and 5b are provided with support portions 8 and 9 which support the band-shaped body receiving portion 6 so as to be rotatable within the groove portion 4 with the shaft portion 7 as a rotation axis.

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

Here, the upright state of the band-shaped body receiving portion 6 means a state in which the short direction of the band-shaped body receiving portion 6 is raised from the groove portion 4 along the radial direction of the roller body 5 .

In the roller body 5, a shaft 2 is attached to one end 5a of the roller body 5 in the axial direction to rotate the roller body 5 by being driven by a drive mechanism provided in the body of the labeling apparatus.

The groove portion 4 provided on the outer peripheral surface of the cylindrical portion 3 constituting the roller body 5 is formed to a depth that does not block the later-described support holes formed in the support portions 8 and 9 . The width of the groove 4 limits the rotatable range of the band-shaped object receiving portion 6, and the wider the width, the wider the range of rotation of the band-shaped object receiving portion 6. As shown in FIG. The width of the groove portion 4 is not particularly limited, but when the belt-shaped object receiving portion 6 standing upright in the groove portion 4 is rotated and knocked down, one side of the belt-shaped object receiving portion 6 protruding from the outer circumference of the roller main body 5 is It is preferable that the width is such that the end on the long side 6a side comes into contact with the opening end of the groove portion 4 .

In this example, the cross-sectional shape of the groove 4 is U-shaped, and a chamfered portion 13 is formed on the top of the wall surface 4a of the groove 4, with which the belt-shaped body receiving portion 6 that is inclined by rotation abuts. By forming the chamfered portion 13 on the top portion of the wall surface 4a of the groove portion 4, the range in which the belt-shaped body receiving portion 6 is rotated can be made wider than when the chamfered portion 13 is not formed.
The shape of the groove portion 4 is not limited to the shape of this example, and other shapes such as a U shape can be adopted.

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

A support portion 8 provided at one end portion 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 portion 5a with a screw 14 .

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

The support hole 15 is positioned so that one long side 6a side of the belt-shaped body receiving portion 6 can protrude from the groove portion 4 when the shaft portion 7 of the belt-shaped body receiving portion 6 is fitted together with a support hole formed in the support portion 9 to be described later. is formed in

In this example, the support hole 15 is formed so as to have a straight portion 15a substantially orthogonal to a radial line extending from the axial center of the roller body 5. As shown in FIG. As a result, the shaft portion 7a fitted in the support hole 15 can move within the support hole 15 along the straight portion 15a.

In addition, a shield portion 16 is formed on the support portion 8 to prevent slippage and detachment of the strip during winding.

Further, the support portion 8 is formed with an insertion hole 17 for inserting the shaft 2 and a hole 18 for passing the screw 14 .

A supporting portion 9 provided at the other end portion 5b of the roller body 5 is formed in a plate shape and attached to the other end portion 5b with a screw 19. As shown in FIG.

Similarly to the support portion 8, the support portion 9 has a support hole that opens in the groove portion 4 of the roller body 5 and is rotatably fitted to the shaft portion 7b that is provided on the other end side of the belt-shaped object receiving portion 6. 20 are formed.

The support hole 20 is formed so as to face the support hole 15 of the support portion 8 . That is, when the support hole 15 formed in the support portion 8 and the shaft portion 7 of the band-shaped body receiving portion 6 are fitted into the support hole 20, one long side 6a of the band-shaped body receiving portion 6 protrudes from the groove portion 4. formed in position.

In this example, the support hole 20 is formed to have a straight portion 20a substantially perpendicular to the radial line extending from the axis of the roller body 5, similarly to the support hole 15 of the support portion 8. As shown in FIG. As a result, the shaft portion 7b of the belt-shaped body receiving portion 6 fitted in the support hole 20a can move within the support hole 20 along the straight portion 20a.

In addition, the supporting portion 9 constitutes a holding means 11 together with a plunger, which will be described later. A hole portion 22 is formed to hold the belt-shaped object receiving portion 6 in a state in which the upright state is released.

Further, the support portion 9 is formed with a hole 23 through which the screw 19 is passed.

The belt-like object receiving portion 6 has a length in the longitudinal direction equal to or greater than the width of the belt-like object to be wound, and a length in the short direction to protrude from the groove portion 4 . The thickness of the belt-shaped body receiving portion 6 is not particularly limited, and it is formed to have a thickness that can withstand the pressure received from the wound belt-shaped body according to the material. As a material used for the band-shaped object receiving portion 6, metal, synthetic resin having high rigidity, or the like is used.

In this example, the belt-shaped body receiving portion 6 is a belt-shaped body that opens toward the other end 5b of the roller body 5 to which the shaft 2 is not attached and extends toward the one end 5a of the roller body 5. The end has a notch 24 into which it can be inserted. The length of the notch 24 in the longitudinal direction is at least equal to the width of the strip to be wound.

The shafts 7 provided at both ends of the other long side 6b side of the belt-shaped body receiving portion 6 may be those that can be rotatably fitted into the support holes 15 and 20 of the support portions 8 and 9, and are particularly limited. not. For example, it is also possible to form the shaft portion 7 by protruding rod-shaped portions from both ends on the other long side 6b side of the band-shaped body receiving portion 6 formed in a rectangular plate-shaped body.

In this example, the long piece 6c on the side of the other long side 6b formed by the notch 24 formed in the belt-shaped object receiving portion 6 is formed into a rod shape, and this serves as the shaft portion 7. As shown in FIG.

The rotary operation means 10 of the operation portion 12 has a structure in which a lever 26 having a handle 25 is attached to a shaft portion 7b on the other end side of the band-shaped body receiving portion 6 in this example. By turning the lever 26 with the handle 25, the belt-shaped body receiving portion 6 is rotated via the shaft portion 7b. It should be noted that the rotary operation means 10 is not limited to this example, and other configurations can be employed as long as the shaft portion 7 can be rotated.

In this example, the shaft portion 7 b on the other end side is projected from the support hole 20 of the support portion 9 , and this projecting portion is used as the lever mounting portion 27 . A hole 29 for mounting the lever 26 with a screw 28 is formed in the lever mounting portion 27 .

In this example, the holding means 11 of the operation part 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 operation means 10. a plunger 31 having a protruding portion 30 which is biased toward 9 and protrudes so as to be able to retract; consists of

When the lever 26 of the rotating means 10 is rotated so that the projecting portion 30 of the plunger 31 of the holding means 11 is fitted into the holding hole 21, the belt-shaped body receiving portion 6 is moved. It is made to be in a standing state. In this example, the upright state of the band-shaped object receiving portion 6 is a state in which the short direction of the band-shaped object receiving portion 6 is aligned with the radial direction of the roller main body 5 . By setting this state to the standing state, the posture can be maintained even if a strong pressure is applied from the strip.

Further, when the lever 26 is rotated to the position where the projecting portion 30 of the plunger 31 is fitted into the holding hole portion 22, the belt-shaped body receiving portion 6 which is in the upright state is rotated to move from the upright state to the maximum rotation position. When it reaches, the projecting portion 30 fits into the hole portion 22 formed in the support portion 9 so that the band-shaped body receiving portion 6 is held at the same position.

In addition, the plunger 31 is provided with a knob 32 for withdrawing the projecting portion 30 that is in a projecting state. can be separated from the holding holes 21 and 22 .

The winding roller having the above configuration is used as follows.
When winding the strip A made of the label backing paper, first, the handle 25 is used to turn the lever 26 to fit the projecting portion 30 of the plunger 31 into the holding hole 21, thereby holding the strip receiving portion 6 in an upright state. do.

Then, the leading end of the strip A is pulled out from the roll of the strip A arranged on the upstream side of the labeling device and wound around the take-up roller 1 . The strip A is wound around the take-up roller 1 by inserting the leading end of the strip A into the notch 24 formed in the strip receiving portion 6, and inserting the strip protruding from the outer peripheral surface of the roller main body 5. Fold over the receiving portion 6 (see FIG. 13), then manually rotate the take-up roller 1 to wind the leading end of the strip A so as not to come off the take-up roller 1 (see FIG. 14).

When the winding of the belt-shaped body A is completed, the labeling device is started and the label is pasted. The strip A from which the label has been peeled off is taken up by a take-up roller 1 rotated by a drive mechanism provided in the body of the labeling apparatus. The wound strip A is lifted at the portion received by the strip receiving portion 6 in the upright state, and becomes a swollen roll (see FIG. 15).

After the completion of label attachment, the belt-shaped body roll B wound on the winding roller 1 into a roll is removed from the winding roller 1 by first pulling the knob 32 provided on the plunger 31, The protruding portion 30 fitted in the holding hole portion 21 is retracted and separated from the holding hole portion 21 to release the belt-shaped body receiving portion 6 from being held in the upright state.

After the band-shaped object receiving portion 6 is released from the upright state, the handle 25 is used to turn the lever 26 to rotate the band-shaped object receiving portion 6 and knock it down (see FIG. 16). Rotation of the belt-shaped object receiving portion 6 is rotated to the maximum rotation position, and the projecting portion 30 of the plunger 31 is fitted into the hole portion 22 at the same position. At this time, in this example, since straight portions 15a and 20a are formed in support holes 15 and 20, shaft portion 7 moves along straight portions 15a and 20a as band-shaped object receiving portion 6 rotates. 6 is moved in the direction opposite to the tilted direction, and the band-shaped object receiving part 6 is retracted in the direction opposite to the tilted direction by the length of the movement of the shaft 7. - 特許庁

When the belt-shaped body receiving part 6 falls down and is retracted by the length of movement of the shaft 7 in the direction opposite to the tilted direction, the projection amount of the belt-shaped body receiving part 6 from the groove part 4 becomes smaller than that in the upright state. In other words, when the belt-shaped object receiving portion 6 falls down and is retracted by the length of the movement of the shaft 7 in the direction opposite to the tilted direction, the length from the projecting end of the belt-shaped object receiving portion 6 to the axial center of the roller body 5 is shorter than in the standing state. As a result, the strip receiving portion 6 that receives the strip A is separated from the strip A, a gap S is generated between the roller main body 5 and the strip A, and the tightening of the strip A to the winding roller 1 is prevented. Loosen (see Figure 16).
From this state, the belt-shaped body roll B is pulled out from the take-up roller 1 .
