Description

  The present invention relates to a label issuing device, and more specifically, a label issuing device using a roll-wrapped label roll paper in which a label is detachably attached to a belt-like mount at a predetermined interval. Regarding the winding of the mount.

  A conventional label issuing apparatus using label roll paper draws a mount from the label roll paper set in the holding section by the operation of the feeding section, guides the pulled mount to the peeling section, and mounts the label at the peeling section. The peeled label is held in the issuing unit, and the mount from which the label is peeled is wound up by the mount winding unit so as not to get in the way. Then, the label peeled off from the mount and held in the issuing unit is automatically attached to the product to be transported and moved by a machine or manually attached by an operator (for example, see Patent Document 1).

By the way, in the feeding section for drawing out the mount from the label roll paper and the mount winding section for winding the mount after the label is peeled off, the feeding section and the mount winding section rotate intermittently and simultaneously or alternately rotate. (Intermittently linked), the board is pulled out from the label roll paper, and the board after the label is peeled off.
However, the diameter of the mount roll take-up section at the initial stage when the new label roll paper is set, and the mount roll take-up section at the time of the label roll paper change just after the mount is pulled out of the label roll paper and the label is low. It differs greatly from the diameter size including the mount.

  As the diameter of the mount winding unit including the mount changes, the rotational movement of the winding shaft in the mount winding unit moves from the center of rotation of the winding shaft to the outermost side of the mount wound on the winding shaft. With this diameter (radius), a moment of inertia is generated in the direction in which the winding shaft rotates. The moment of inertia increases as the diameter increases.

  Accordingly, when the moment of inertia is applied to the rotation of the mount winding portion, the label (mounting) to be stopped at a predetermined position is strongly pulled in the pulling direction (winding direction of the mount winding portion), and downstream from the predetermined stop position. On the side, for example, about 1/4 to 1/3 of the label length is drawn and wound. Then, when the mount is excessively drawn out and taken up by the mount take-up unit, the predetermined length is pulled out from the label roll paper by the operation of the next feeding unit, and the first (target) label stuck on the mount is peeled off. , But the part of the next label which should not be peeled yet will be peeled off from the mount.

As a result, when the peeled label is automatically attached by a machine, it causes a label sticking error or a peeling failure.
In addition, when the peeled label is put on standby at the peeling portion and air is blown on the waiting label to be pasted or manually attached by an operator, the label to be used next on the waiting state label at the peeling portion Will continue to be peeled off, and the leading edge of the label to be used next will be attached to the rear end of the standby label, and two sheets will be discharged, and when they are peeled off to separate them, Since the printed surface of the lower label cannot be peeled off or is stained with glue, eventually both sheets cannot be used, and the label is wasted.
In addition, when the label issuing device includes a printing unit, in addition to the above-described problems, there is a problem that printing deviation occurs with respect to the label.

Japanese Patent Laid-Open No. 11-171151

  The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide a label issuing device using label roll paper, and to wind the paper accompanying the winding of the mount in the mount winding unit. Provided is a label issuing device capable of stably and surely issuing a label at a predetermined position without being affected by an increase in diameter.

In order to achieve the above object, the label issuing apparatus of the present invention includes a holding unit that rotatably holds a roll of rolled label roll paper in which a label is peelably attached to a strip-like mount at a predetermined interval; A feeding unit that rotates the label roll paper of the holding unit to draw out the mount, a peeling unit that peels the label from the mount drawn by the operation of the feeding unit, and a mount winding that winds the mount after peeling the label In the label issuing device provided with a section, the feeding section is disposed downstream of the peeling section, and a frictional force is applied to the mount wound by driving the mount winding section between the feeding section and the mount winding section. The present invention is characterized in that a braking force applying means for applying the pressure is disposed (claim 1).
In the label issuing device, predetermined items are printed on the label in advance, and the label issuing device is attached to the strip-shaped mount so that the label can be peeled off. It includes both a so-called label print issuing device provided with printing means on the upstream side.
Further, the position where the braking force applying means is installed is located on the winding path in contact with the outer peripheral surface of the winding core of the mount winding section.
The label peeled off from the mount by the peeling part is automatically stuck on the product being transported by the sticking means, or is held by the label holding part (issuing part) arranged in front of the peeling part and used for manual sticking. is there.

  According to the above means, the mount is pulled by the driving of the feeding portion, the label roll paper is rotated, and the mount with the label attached is pulled out by a predetermined length. The pulled-out mount passes through the peeling section, and the label is peeled off from the mount and is held by the issuing section. The mount from which one label is peeled is driven by the mount winding section. It is wound on a winding core. As the labels are peeled and issued one by one from the mount by driving the feeding section, the winding diameter of the mount wound around the core of the mount winding section gradually increases. And although an inertia moment arises in the rotation direction of this mount winding part, the inertia moment which arises with the diameter change (small-> large) of the said winding diameter also becomes large. The moment of inertia acts on the drive of the mount take-up unit and tries to pull out the mount excessively, but the friction force is applied to the mount taken up by the drive of the mount take-up unit by the braking force applying means, and the take-up unit The brake works on the rotation. Thereby, the label which should stop at the sticking part downstream from a peeling part can be moved further downstream (winding direction of a mount), and it can prevent peeling from a mount until the next label. Thereby, label sticking mistake and peeling failure can be prevented. Further, when the label issuing device is a label printing issuing device provided with printing means, it is possible to prevent the occurrence of printing defects (print position deviation).

  The arrangement position of the braking force applying means is a position where the contact area of the mounting with the braking force applying means increases as the winding diameter of the mount winding portion increases. Specifically, with respect to the tangent line between the outer peripheral surface of the feeding portion for pulling out the mount and the winding core outer peripheral surface of the mount take-up portion for winding the mount from which the label is peeled, or the tangent line It arrange | positions in the side in which the axial center of a delivery part and a mount winding part is located.

The braking force applying means may be fixed at a predetermined position (on a tangent line connecting the outer peripheral surface of the feeding portion and the outer peripheral surface of the winding core of the mount winding portion, or on the inner side of the tangent). Further, the position may be adjustable so that the contact area with the mount can be varied (claim 2).
As the position-adjustable attachment, for example, a long hole is formed in a pedestal provided with a braking force applying means, and a screw is passed through the long hole so that it can move within the range of the long hole.

  According to the above means, the frictional force applied to the mount can be adjusted in strength by changing the position of the braking force applying means for applying the frictional force to the mount that moves by driving the mount take-up unit. As a result, it is possible to cope with changes in friction resistance due to changes in humidity (changes in the moisture content of the backing sheet) and changes in the label supplier, etc., and there are defects in the initial settings (such as misalignment of the label stop position). Even in such a case, the above-mentioned problem can be solved by finely adjusting the position of the braking force applying means. Further, the frictional force acting on the mount can be adjusted by adjusting the position, and it is possible to increase the winding density on the winding portion and tighten the winding. As a result, even though there is still remaining amount on the label roll paper side, there is no winding allowance on the mount take-up unit side, and work such as rewinding to ensure winding allowance is required. The above-described rewinding is not necessary due to the tightening (high frictional force) to wind with increasing density.

As the braking force applying means, for example, a shaft rod having a shaft core arranged in parallel with the surface of the moving mount, and a friction portion is formed on the outer surface of the shaft contacted with the mount (Claim 3). .
The number of shaft rods that apply frictional force to the mount is not limited to one, and a plurality of shafts may be used.
Further, the friction portion may be formed integrally on the outer surface of the shaft rod (Claim 4), or may be provided in such a manner that a friction member, which is a separate member from the shaft rod, can be attached and detached.
As a form in which the friction portion is integrally formed on the outer surface of the shaft rod, the outer surface of the shaft rod made of metal (for example, iron, stainless steel, etc.) is roughened on the outer surface (for example, knurled, satin-like rough surface, serration, etc.) ).
As a form in which the friction member is detachably mounted on the shaft rod, a rubber material having a large friction coefficient, a rod-shaped member, etc. are wound around the outer peripheral surface of the shaft rod and integrated (adhesion, band tightening, etc.), and wear due to long term use If the initial friction force cannot be applied, replace it.

  According to the above means, the mount pulled by the drive of the mount winding portion is wound around the outer peripheral surface of the shaft rod by the contact diameter. As the winding diameter of the winding portion increases, the contact area of the mount with respect to the shaft rod increases, and the frictional force applied to the mount also increases. Therefore, it is possible to apply a frictional force to the mount with a very simple configuration.

According to the label issuing device of the present invention, the label attached to the mount drawn by the operation of the feeding portion can be stopped at a predetermined position. Thereby, it is possible to prevent label sticking mistakes and peeling failures, and in the label issuing device provided with the printing means, printing failures can be prevented.
In addition, according to the configuration of claim 3, it is possible to cope with changes in frictional resistance due to changes in humidity (changes in the moisture content of the mount) and changes in the label supplier due to changes in the label supplier, etc. Even when there is a positional deviation or the like, the above problem can be solved by finely adjusting the position of the braking force applying means. And it becomes possible to increase the winding density to a winding part, and to wind up.
Furthermore, according to the configurations of claims 4 and 5, it is possible to reliably apply a frictional force to the mount with an extremely simple configuration.
Further, according to the configuration described in claim 6, it is possible to always maintain an optimum frictional force by exchanging the friction part. Therefore, stable label issuance and label printing can be ensured over a long period of time.

Hereinafter, an example of an embodiment of a label issuing apparatus according to the present invention will be described with reference to the drawings.
FIG. 1 is a plan view showing an outline of a label issuing device A provided with a label applying means. A roll of rolled label roll paper 1 in which a label 1b is attached to a strip-like mount 1a so as to be peeled at a predetermined interval. A holding unit 2 that is rotatably held, a feeding unit 3 that pulls out the mount from the label roll paper 1 held by the holding unit 2, and a label that is attached to the mount 1 a that is pulled out by the operation of the feeding unit 3 1b is peeled off from the mount 1a, a sticking means 5 for sticking the label 1b peeled off at the peeling portion 4 to a product to be transported and moved, and the operation of the feeding unit 3 is provided downstream of the feeding unit 3. A mount take-up unit 6 that winds up the empty mount (the label is peeled off) that has been pulled out, and a braking force applying means 7 that is disposed in the mount transfer path from the feed unit 3 to the mount take-up unit 6; It consists of

  The label roll paper 1 is one in which a label 1b is detachably attached to a side surface of a long strip-like mount 1a and is wound around a roll. The label 1b to be attached to the mount 1a is predetermined. Items are printed. When the label issuing device A is provided with a printing means upstream from the peeling unit 4, the label roll paper 1 set in the holding unit 2 has an empty label (a label on which no predetermined matter is printed). Use attached label roll paper.

In the middle of the path from the holding part 2 to the peeling part 4, meander prevention means 8 for preventing the mount 1a drawn by the operation of the feeding part 3 from meandering is disposed.
The meandering prevention means 8 includes a roller 8a having ridges on both sides in the axial direction slightly wider than the roll width of the label roll paper 1 (the width of the mount 1a), a swing arm 8b that supports the roller 8a, and the swing The roller 8a supported by the arm 8b is configured by a spring 8c that urges the roller 1a toward the mount 1a, and the side of the swing arm 8b opposite to the side supporting the roller 8a is pivoted to the substrate 9. The installation position of the meandering prevention means 8 is the side where the center of the holding part 2 is located with respect to a tangent line connecting the outer peripheral surface of the holding part 2 that holds the label roll paper 1 rotatably and the tip of the peeling part 4. As a result, the label roll paper 1 is guided by being brought into contact with the roll path mount 1a, so that tension is applied to the label roll paper 1 in the supply path and the roll path mount 1a, and the meandering of the label roll paper 1 is reduced. Is configured to do.

  The feeding unit 3 pulls out the base 1a on which the label 1b is adhered from the label roll paper 1, and is composed of a pair of driving rollers 3a and a follower presser roller 3b. The mount 1a from which the label 1b is peeled is wound around the outer peripheral surface of the drive roller 3a, and the driven press roller 3b is urged so as to press the mount 1a against the drive roller 3a. The drive roller 3a is configured to be driven to rotate only in a direction in which the mount is pulled out by a stepping motor (not shown).

  The peeling unit 4 peels the label 1b from the mount 1a by bending and moving the mount 1a drawn from the label roll paper 1 set in the holding unit 2 by the operation of the feeding unit 3, It consists of a flat plate made of resin or a flat plate made of resin. Then, the mount 1a turned back at the peeling section 4 is guided to the feeding section 3, and the mount 1a fed downstream from the feeding section 3 by the operation of the feeding section 3 is wound up by the mount winding section 6 and peeled off. The label 1b is pasted on the product W by the pasting means 5.

The sticking means 5 sticks the label 1b peeled off at the peeling portion 4 to the product W, and a sticking roller 5b is rotatably supported on one side end of the arm 5a. The middle part is pivotally supported by the board 9 so as to be swingable, and a spring 5c for biasing the sticking roller 5b in a direction in contact with the product W on the side of the arm 5a opposite to the sticking roller 5b. It is stretched over. The end of the arm 5a opposite to the sticking roller 5b is fitted and engaged with a long hole 10 formed in the substrate 9, and the swing range of the arm 5a is restricted.
As shown in FIGS. 1 and 4, sticking of the label 1b by the sticking means 5 is performed by the product W moving on the product transporting device B arranged along the label issuing device A, and the product W is attached to the sticking roller 5b. By moving while abutting on the outer peripheral surface, the leading edge side (the first peeled side) of the label 1b peeled off from the mount 1a is in contact with the product W, and is sequentially peeled off from the leading end side in the moving direction of the mount. The label 1b is adhered to the side surface of the product W by the movement of the product W and is pressed by the application roller 5b to be securely attached.
In addition, when the sticking means 5 is not provided, the issuing part which temporarily holds the label 1b peeled off by the peeling part 4 can be attached in the vicinity of the peeling part 4 to hold the label 1b peeled off from the mount 1a. Like that.

  The board take-up unit 6 operates the feeding unit 3 to draw out the length required for the board 1a to peel and issue one label from the label roll 1 and simultaneously feed the board 1a from which the label 1b has been peeled off. Although it sends out downstream from the part 3, the board | substrate 1a sent out downstream from the delivery part 3 is wound up in roll shape. Specifically, the winding core 6a is driven and rotated by a stepping motor (not shown) or the like, and the mount 1a fed downstream from the feeding unit 3 by the operation of the feeding unit 3 is taken up. Therefore, the mount winding unit 6 rotates intermittently while interlocking with the feeding unit 3.

And since this mount winding part 6 winds up the mount 1a after the label 1b was peeled one after another, the winding diameter gradually becomes larger as the mount is wound. At the time of rotation of the mount winding portion 6, an inertia moment is generated in the winding portion in the rotation direction. However, the inertia moment is small at the stage of a small diameter when the mount 1a is started, and it is easy to turn and stop. As the diameter increases, the moment of inertia also increases, making it difficult to turn and stop. Then, the mount 1a is pulled excessively by inertial rotation due to the moment of inertia, the label roll 1 set in the holding unit 2 is rotated, and the mount 1a with the label 1b attached is pulled out, and as a result, it is still peeled off. There is a problem that the next label 1b that should not be partly peeled off by the peeling part 4 (the stop position of the label changes).
In order to prevent the excessive withdrawal of the mount due to the moment of inertia generated in the rotation of the mount take-up unit 6, a frictional force (resistance) is applied to the mount 1a that travels between the path from the feeding unit 3 to the mount take-up unit 6. A braking force applying means 7 for applying and braking the running of the mount 1a is disposed.

The braking force applying means 7 is configured by forming a friction portion 7b on the outer peripheral surface of a metal shaft rod 7a, and the metal shaft rod 7a is substantially parallel to the surface of the mount 1a that travels on the shaft core. In such a manner, it is vertically arranged on the substrate 9.
The friction portion 7b is configured so that the outer surface of the metal shaft rod 7a is processed into a knurled shape, and a frictional resistance is generated in the mount 1a that comes into contact.

Further, the arrangement position of the braking force applying means 7 constituted by the metal shaft rod 7a is such that the contact area of the mount 1a with the metal shaft rod 7a increases as the winding diameter of the mount winding portion 6 increases. The position where the frictional force increases and the frictional force increases. Specifically, on the tangent line L connecting the outer peripheral surface of the driving roller 3a of the feeding unit 3 and the outer peripheral surface of the winding core 6a of the mount winding unit 6, or the center of the driving roller 3a and the mount with respect to the tangent L The center of the metal shaft rod 11a is arranged on the side (inside) where the center of the winding core 6a of the winding unit 6 is located.
Thereby, when the mount winding diameter of the mount winding unit 6 is small, the contact area of the mount 1a with the metal shaft 11a is small, and with the outer diameter of the metal shaft 11a as the mount diameter increases. The contact area increases and the frictional force also increases.

Further, the braking force applying means 7 may be fixed at the above position, but the initial setting state changes due to changes in the humidity, the material of the mount 1a, and the friction portion 7b of the metal shaft 7a. You may attach so that position adjustment is possible for the fine adjustment etc. which return a state to the original state.
As a specific configuration, for example, as shown in FIG. 3A, a metal shaft rod 7a is erected and fixed to a base 11, and a screw-through hole 12 for screwing the base 11 to the board 9 is long. A set screw 13 is inserted into the screw hole 12 and fixed. As a result, the pedestal 11 holding the metal shaft 7a upright with respect to the set screw 13 fixed to the substrate 9 can move horizontally within the range of the long hole of the screw through hole 12, and the outer periphery of the metal shaft 7a. The range of the contact area between the surface and the mount 1a can be adjusted.

Further, the friction portion 7b in the braking force applying means 7 is not limited to a form in which the metal shaft rod 7a itself is processed and formed integrally, but the friction portion 7b is configured separately from the metal shaft rod 7a. You may attach the friction part 7b of another member with respect to the metal shaft rod 7a so that attachment or detachment is possible.
For example, as shown in FIG. 3 (b), a rubber cylinder 14 having a large friction coefficient is fitted to a metal shaft 15 and fixed with a presser screw 16. In addition to the rubber material, a flange-like member, a resin or metal tube having an uneven rough surface, a belt member having an uneven rough surface, or the like can be used as the friction portion of the separate member.

The label issuing device A configured as described above is disposed on the side of the conveyance path 17 of the product conveyance device (belt conveyor) B as shown in FIGS. A label 1b peeled off from the backing 1a of the label roll paper 1 is automatically attached to the side surface of a product W (illustrated "onigiri" is shown) conveyed by the rotational movement.
A frictional force (resistance) is applied to the traveling board 1a between the path from the feeding unit 3 to the board winding unit 6 in the label issuing device A to brake the running of the board 1a. Since the braking force applying means 7 is arranged, it is possible to prevent the mount from being pulled and wound more than necessary due to the moment of inertia generated when the mount is rotated by driving the mount winding section 6. That is, one label is peeled off from the mount, and the next label stops at a predetermined position to prepare for the next peeling operation.

  Moreover, the frictional force applied to the mount 1a by the braking force applying means 7 is the friction portion of the metal shaft 7a constituting the braking force applying means 7 as the winding diameter of the mount winding portion 6 increases. The contact area between 7b and the mount 1a increases, and the frictional force acting on the mount also increases. Accordingly, the mount winding diameter of the mount winding unit 6 increases, and even if the moment of inertia generated during winding increases, the frictional force acting on the mount also increases accordingly. Can be prevented. Thus, the label 1b is normally peeled off at the peeling portion 4 from the start of use of the label roll paper 1 (the state of the solid line of the label roll paper 1 in FIG. 1) to the end (the state of the imaginary line of the label roll paper in FIG. 1). be able to.
