Description

The present invention relates to a peeling mechanism that is used for a recording medium in which labels are continuously attached to a belt-like mount, and particularly, peels the belt-like backing in the reverse conveyance direction by a peeling means to peel the label from the belt-like mount.

Conventionally, as a label printer provided with a peeling unit for peeling a label from a mount, for example, one disclosed in Patent Document 1 and shown in FIG. 3 is known.
A conventional label printer (printing apparatus) will be described with reference to FIG. 3. This label printer 31 is a “peeling type printer”, and mainly includes a label supply shaft 32, a print head 33, and a platen roller (hereinafter referred to as “printing type printer”). A printing unit 35 having a 34 (appropriately referred to as “platen”), a take-up shaft 36, a position detection sensor 37, a peeling unit 38, and a peeling label detection sensor (hereinafter appropriately referred to as a label sensor) 39.
A label continuum 40 as a “recording medium” is attached to the label supply shaft 32. As shown in the enlarged view of the figure, the label continuum 40 is temporarily attached with a label L on a belt-like mount (hereinafter referred to as “mount” as appropriate) D at substantially equal intervals. An unillustrated identification mark called “eye mark” is printed in advance. The gap between the identification marks (not shown) is formed at a constant pitch, and the label L temporarily attached between the pitches is used as a single “label piece”.
The label continuum 40 mounted on the label supply shaft 32 is fed to the downstream printing unit 35 through the guide roller 41, inserted between the printing head 33 and the platen 34, and further turned by the peeling unit 38 to be mounted. Only D is wound around the winding shaft 36 through the guide roller 42.
When print information (not shown) such as predetermined print data and the number of prints is input from a known input means (not shown), the label continuum 40 is turned as a “conveying roller” that rotates via a drive source such as a motor (not shown). The printing unit 35 prints desired print data (not shown) on the label L while being fed from the label supply shaft 32 by the platen 34 and the take-up shaft 36 and wound onto the take-up shaft 36. By turning the mount D at the peeling portion 38, the label L is peeled from the mount D, and the rear end portion of the label L is placed on the mount D of the peeling portion 38 from the issuing port 43. It is to be issued.
When the issued label L is pinched with a finger or the like and removed from the peeling portion 38, it is detected that the label L is taken out by the peeling label detection sensor 39 provided in the vicinity of the issuing port 43.

By the way, the label continuum 40 used in the label printer 31 uses a label L having a different size (length and width in the pitch direction) depending on the type and amount of information. In particular, an object to be affixed / displayed with a label L (not shown) is small, or an object to be affixed / displayed in a narrow range such as a printed circuit board (not shown) In some cases, a label L having a small pitch (having a small length in the pitch direction between identification marks) may be used.
However, when the label L has a small pitch, there is a problem that the peeled label L is difficult to see.
That is, the peeling portion 38 is formed inside the housing 44 of the label printer 31. If the label has a long length in the pitch direction, the tip protrudes from the issuing port 43. In some cases, the tip portion may not protrude from the issuing port 43, and it was difficult to know whether or not the printing was issued.

JP 2001-38966 A

The present invention has been made paying attention to the above-mentioned problems, and is used for a recording medium in which labels are continuously attached to a belt-like mount, and in particular, the belt-like backing is folded back in the reverse conveyance direction by a peeling means. Thus, an object of the present invention is to provide a peeling mechanism that makes it easy to see the label on the peeled peeling means when peeling the label from the belt-like mount.

The recording medium peeling mechanism according to the present invention includes a transport unit including a transport roller configured to transport a recording medium in which a plurality of labels are continuously attached to a strip mount, and a strip mount provided in the middle of transporting the recording medium. The label is peeled by turning, and the peeling means that is pivotally supported by a rotating shaft so that the downstream side rotates, and is pressed by the conveying roller and downstream of the peeling means. And a pressure roller that sandwiches and conveys the belt-like mount that has been turned by the peeling means, and a rotating means that is provided to rotate the downstream side of the peeling means.
Further, the rotating means can be provided with an indicator portion indicating the amount of rotation of the peeling means.

The recording medium peeling mechanism of the present invention includes a peeling means provided on the rotating shaft so as to rotate the downstream side while peeling the label by turning of the belt-like mount provided in the course of transporting the recording medium, and the peeling means Rotation means provided to rotate the downstream side of the plate, and by rotating the rotation means, the peeling plate can be rotated and positioned at an arbitrary angle and an optimum angle. is there.
In addition, a pressure roller is provided on the downstream side of the peeling means to be pressed by the conveying roller and sandwiched between the conveying rollers and conveyed by the peeling means. Therefore, there is an effect that the peelability of the label from the belt-like mount is improved.
Further, if the indicator means indicating the amount of rotation of the peeling means is provided in the rotation means, the guideline for the rotation amount can be easily understood.

It is a schematic side view of the peeling mechanism part of the printing apparatus carrying the peeling mechanism which concerns on this invention. It is an enlarged schematic side view of the peeling mechanism part including an indicator part. It is a schematic side view of the printing apparatus equipped with the conventional peeling mechanism.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
The same parts as those in the prior art (background art) are designated by the same reference numerals, and detailed description thereof is omitted.
FIG. 1 is a schematic side view of a printing apparatus 31 equipped with a peeling mechanism 1 according to the present invention, and FIG. 2 is an enlarged schematic side view of a peeling mechanism portion including an index portion.
As shown in the figure, the peeling mechanism 1 includes a platen 34 as a conveying roller, a peeling means 2, a pressure roller 3, and a rotating means 4.

The platen 34 functions as a “conveying roller” that rotates via a drive source such as a motor (not shown). The recording medium 40 is sandwiched between the platen 34 and the recording medium 40 is moved downstream by the rotation of the platen 34. It conveys to the peeling plate 2 side.
The “transfer means” is mainly formed by the platen 34 and the winding shaft 36 of the mount D.

  The peeling means 2 is a “peeling plate” formed at an acute angle on the downstream side of the tip, and a rotating shaft 5 is provided at an arbitrary position on the upstream side. The peeling plate 2 around the rotating shaft 5 is It is pivotally supported so that the downstream side of the tip is rotated.

  The pressure roller 3 is provided on the downstream side of the peeling plate 2 so as to be pressed by a platen 34 as a “conveying roller”, and the mount D that is turned by the peeling plate 2 is sandwiched between the platen 34 and transferred. Have a role.

The rotation means 4 includes a rotation fixing member 6 that rotates the front end portion (the left end portion in FIGS. 1 and 2) of the peeling plate 2, a guide groove 7, and an index portion 8.
The rotation fixing member 6 is provided on the side surface on the distal end side of the peeling plate 2 and is provided so as to protrude from the side surface of the housing 44 (front side in the figure), and with a bolt and a nut so that it can be fixed at a desired position. The “locking member” is provided.
The guide groove 7 is an arcuate groove portion formed on the side surface (front side in the figure) of the housing 44, and the rotation fixing member 6 provided to protrude from the peeling plate 2 to the side surface follows the groove. Thus, the tip end portion of the peeling plate 2 is rotated about the rotation shaft 5.
The indicator portion 8 is a “scale” provided beside the guide groove 7, and indicates an indication of the amount of rotation of the rotation fixing member 6 that slides along the guide groove 7. In other words, the amount of rotation of the label L to be issued is a measure of how much the label L is to be rotated. After rotating to a desired position, the label L is peeled off by being fixed by the rotation fixing member 6. The plate 2 is positioned at a desired rotation position (a desired position in the vertical direction in the figure).
The “scale” can be displayed by displaying the pitch of the label L (◯ to Xmm), the inclination angle of the peeling plate 2, and the like.

Next, the use state of the peeling mechanism 1 will be described mainly based on FIG.
When issuing a label L having a long length in the pitch direction, the rotation fixing member 6 is rotated upward along the guide groove 7 and positioned at the upper end portion of the guide groove 7. The tip of the peeling plate 2 is turned upward by the rotation fixing member 6 rotated while sliding, and the upper end of the peeling plate 2 is in a substantially horizontal state (indicated by a dotted line in the figure). ).
When the leading end of the peeling plate 2 is rotated upward and a label L having a long length is issued at the position 2X where the upper end of the peeling plate 2 is substantially horizontal, the leading end of the label L protrudes from the issuing port 43. Therefore, it can be visually confirmed that it has been issued.
On the other hand, when a small-pitch label L having a short length in the pitch direction is issued at the position 2X of the release plate 2 described above, the label L protrudes slightly from the release plate 2, and the tip does not protrude from the issue port 43. Whether the label L is issued because the line of sight E1 is blocked by the housing 44 when viewed with the eyes E of an operator (user) who often stays in the housing 44 and often stands up and issues a label. Not only is it difficult to understand, but the label L is difficult to remove.

Based on the above, when issuing a small pitch label L, the rotation fixing member 6 is rotated downward along the guide groove 7, and the tip 2 of the peeling plate 2 is inclined downward 2Y (in the figure) , Positioned in imaginary lines). That is, when the fixing by the rotation fixing member 6 is released, the rotation fixing member 6 is rotated downward along the guide groove 7, and positioned at the lower end portion of the guide groove 7, the rotation protruding to the side surface of the peeling plate 2 is performed. The peeling plate 2 is positioned by the movement fixing member 6 with its tip portion rotated downward.
When the small pitch label L is issued in the state where the peeling plate 2 is in the position 2Y, the tip of the peeling plate 2 is rotated below the issuing port 43. Therefore, when seen with the eyes E of the operator, the line of sight E2 is It is easy to visually recognize the issuance of the label L without being blocked by the housing 44, and the label L is easily removed by a finger or tweezers because the label L is rotated to an arbitrary position in the vertical direction.
In addition, since the peeling plate 2 rotates about the rotation shaft 5, the distance between the print head 33 and the tip of the peeling plate 2 does not change, so that the peeling plate 2 is rotated to an arbitrary position. However, there is no influence on the control of printing, peeling, and conveyance on the label L.

  As described above, the mount D turned by the peeling plate 2 is sandwiched between the platen 34 as the “conveying roller” and the pressure roller 3, and then the pressure roller 3 is pressed against the platen 34 and conveyed. Since the tensile force with respect to the mount D is improved, the peelability of the label L from the mount D in the release plate 2 is improved as compared to the conventional mount take-up taken up by the take-up shaft. Even when 2 rotates and is positioned at a position 2Y where the front end portion is inclined downward, and the turning angle of the mount D is changed to a large angle, there is no possibility that the peelability is lowered.

  Further, since the rotation fixing member 6 can be rotated along the guide groove 7 and fixed at an arbitrary position, the user can put the peeling plate 2 at an optimum angle at which the label L issued and staying on the peeling plate 2 can be visually recognized. It can rotate.

  It should be noted that the configuration and operation of the above-described embodiment are examples, and it is needless to say that they can be changed as appropriate without departing from the spirit of the present invention.

  For example, the peeling detection sensor 39 in the prior art is provided outside the issuing port 43, but it is desirable to provide the peeling detection sensor 39 in the vicinity of the peeling plate 2 inside the housing 44 so that a small pitch label can be easily detected. .

In the above embodiment, for convenience of explanation, the example in which the label L printed on the recording medium 40 by the printing unit 35 is peeled off by the peeling plate 2 has been described. However, the present invention is not limited to this. Yes, for example, it may be used in a peeling machine for peeling a so-called promotional label on which contents such as “bargain” and “price-reduced product” are printed in advance.
