BACKGROUND OF THE INVENTION
The present invention relates to a label peeling device mounted on a printer body having a printing function.
[0002]
[Prior art and its problems]
2. Description of the Related Art Conventionally, various types of label peeling apparatuses for peeling a printed label from a mount have been proposed. However, the conventional label peeling apparatus has a structure in which a peeling roller for pulling the mount is housed in the apparatus, and it takes time to load the label paper. Also, a structure in which the peeling roller is exposed to the outside of the apparatus has been proposed, but in this type of label peeling apparatus, although label paper can be easily loaded, dust or the like adheres to the peeling roller. As a result, the mount clamping force becomes non-uniform, which may cause malfunction.
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a label peeling apparatus in which loading of label paper is easy and dust and the like are not easily attached to the peeling roller.
[0003]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is a label peeling apparatus which is attached to a printer body having a printing function and peels a label from a mount of label paper conveyed from the printer body, and has the following configuration. It is characterized by that.
(A) A frame having a hollow portion with an open front surface and an introduction port for introducing label paper conveyed from the printer main body into the hollow portion on the back portion
(B) A peeling member that is supported by the frame and that curves the mount of the label paper introduced from the introduction port in the hollow portion of the frame and peels the label from the mount
(C) A pair of driving peeling roller and driven peeling roller for holding the mount on the downstream side of the peeling member in the hollow portion of the frame and pulling the mount by a rotating operation
(D) A holder that rotatably supports the driven peeling roller and is rotatably supported by the frame, and is detachable from the opening of the frame into the hollow portion.
[0004]
In the present invention configured as described above, since the driving peeling roller and the driven peeling roller are housed in the hollow portion of the frame, dust is not easily attached to these peeling rollers, and therefore, the mount can be stably held and pulled out. .
[0005]
In addition, since the driven peeling roller can be separated from the driving peeling roller and the opening on the front surface of the frame can be opened by rotating the holder, the label paper can be easily loaded from the opening.
[0006]
Further, when the holder is inserted into the hollow portion of the frame and the surface of the holder is arranged on the same plane as the front surface of the frame, an excellent appearance quality without protrusions can be obtained.
[0007]
In addition, the holder can be slidable in the axial direction with respect to the frame, and can be provided with a locking means for always urging in one sliding direction and locking the holder inserted into the hollow portion to the frame.
Here, in order to maintain the pressure contact state between the driven peeling roller and the driving peeling roller, it is necessary to apply a large resistance force to the external force acting in the direction in which the holder is pulled out. Therefore, if the holder is to be pulled out of the hollow portion by a turning operation around the axis, a large force against the resistance force is required. For this purpose, an operation recess having a sufficient size and a handle must be formed in the holder.
Therefore, when the holder is slid in the other sliding direction (that is, the direction opposite to the urging direction), the holder can be easily pulled out with a simple operation if the locking means is configured to release the locked state. be able to. As a result, the operation recess and handle can be reduced, and the holder and thus the apparatus can be miniaturized.
[0008]
Further, if a biasing means for biasing the driven peeling roller in a direction in contact with the driving peeling roller is provided between the holder and the driven peeling roller, the mount can be securely sandwiched between the peeling rollers. it can.
[0009]
Furthermore, if the peeling member is formed of a small-diameter roller member and is configured to be rotatably supported, the frictional resistance between the peeling member and the mount that is curved there is reduced, and power loss is reduced. Can be planned.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0011]
Overall configuration of label printer
FIG. 1 is a sectional side view showing an outline of a label printer equipped with a label peeling apparatus according to an embodiment of the present invention. First, the overall configuration of the label printer will be described with reference to FIG.
The label printer includes a printer main body 100 having a printing function, a paper supply reel (not shown), and a label peeling device 200.
[0012]
A paper supply reel (not shown) is mounted on the back side of the printer main body 100 (the right side surface in FIG. 1). FIG. 11 shows an example of label paper continuously supplied from the paper supply reel. In the label sheet 1 shown in the figure, labels 3 are affixed at regular intervals to the surface of a backing sheet 2 that is continuous in a strip shape. The label paper 1 is wound around a paper supply reel, pulled out from the leading end, and continuously supplied to the printer main body 100.
[0013]
Inside the printer main body 100, a thermal printing type print head 101, a platen 102, a ribbon supply shaft 103, and a ribbon take-up shaft 104 are provided, and a ribbon supply reel 105 is mounted on the ribbon supply shaft 103, A ribbon take-up reel 106 is mounted on the ribbon take-up shaft 104.
[0014]
The print head 101 and the platen 102 are provided facing each other, and the print head 101 is pressed against or separated from the platen 102 by manual operation of a head lever (not shown).
[0015]
The ribbon supply reel 105 is wound with an ink ribbon 107 that is continuous in a strip shape. The ink ribbon 107 drawn from the ribbon supply reel 105 is taken up by the ribbon take-up reel 106 via the print head 101 and the platen 102.
[0016]
Between the print head 101 and the platen 102, the label paper 1 pulled out from the paper supply reel is supplied together with the ink ribbon 107, and the ink ribbon 107 and the label paper 1 are overlapped with each other. Here, the operation of sandwiching the ink ribbon 107 and the label paper 1 between the print head 101 and the platen 102 is performed in a state where the print head 101 is separated from the platen 102 by manual operation of the head lever (not shown). .
[0017]
The print head 101 generates heat based on a control signal from a control unit (not shown) and melts ink applied to the ink ribbon 107. Then, the melted ink is transferred to the label 3 of the label paper 1.
[0018]
The platen 102 has a pedestal function for supporting the ink ribbon 107 and the label paper 1 during the printing operation. Further, the platen 102 is rotationally driven as will be described later, and also functions as a paper transport unit that pulls out the label paper 1 from the paper supply reel and transports it to the label peeling unit 200 side. The ink ribbon 107 is pulled out by rotating the ribbon take-up shaft 104.
[0019]
The label peeling device 200 includes a peeling member 201, a driving peeling roller 202, and a driven peeling roller 203, and has a function of automatically peeling the label 3 from the mount 2 of the label paper 1 conveyed from the printer main body 100. Have.
[0020]
The driven peeling roller 203 is in pressure contact with the driving peeling roller 202 and pulls the backing sheet 2 of the label sheet 1 in cooperation with each other. That is, the mount 2 of the label sheet 1 conveyed from the printer main body 100 is sandwiched between the driving peeling roller 202 and the driven peeling roller 203 via the peeling member 201 and pulled by the rotational driving of the driving peeling roller 202. . In this process, the mount 2 is bent by the peeling member 201, and the conveyance direction is changed to a steep angle. On the other hand, the label 3 passes straight through the peeling member 201 without being bent. As a result, the label 3 is peeled off from the mount 2 with the peeling member 201 as a boundary.
The detailed structure of the label peeling apparatus 200 will be described later.
[0021]
Drive mechanism in the printer body
FIG. 2 is a configuration diagram showing a drive mechanism in the printer body.
A drive motor 108 is provided inside the printer main body 100, and the platen 102 and the ribbon take-up shaft 104 are rotationally driven using this as a drive source. That is, the drive side pulley 109 is attached to the rotation shaft of the drive motor 108, while the platen side driven pulley 110 is attached to the rotation shaft of the platen 102. A power transmission belt 111 is wound around the pulleys 109 and 110, and the rotational driving force of the drive motor 108 is transmitted to the platen 102 via the power transmission belt 111.
[0022]
A first power transmission gear 112 is attached to the rotating shaft 102 a of the platen 102. Further, the printer main body 100 is provided with a rotary shaft 113 for power transmission, and a second power transmission gear 114 is attached to the rotary shaft 113. The second power transmission gear 114 is in mesh with the first power transmission gear 112.
[0023]
A power transmission pulley 115 is attached to the rotary shaft 113 for power transmission together with the second power transmission gear 114, while a driven pulley 116 is attached to the ribbon take-up shaft 104. A power transmission belt 117 is wound between these pulleys 115 and 116, and the rotational driving force of the drive motor 108 transmitted to the second power transmission gear 114 is wound on the ribbon via the power transmission belt 117. This is transmitted to the take-up shaft 104.
[0024]
When the label sheet 1 is fed out, the drive motor 108 rotates counterclockwise in FIG. 2, and the platen 102 rotates counterclockwise through the power transmission belt 111. By this rotation, the platen 102 cooperates with the print head 101 to convey the label paper 1 in the delivery direction (left direction in FIG. 2).
[0025]
The first power transmission gear 112 rotates counterclockwise integrally with the platen 102, and the second power transmission gear 114 that meshes with the first power transmission gear 112 rotates clockwise in FIG. This rotation is transmitted to the ribbon take-up shaft 104 via the power transmission belt 117, and the ribbon take-up shaft 104 similarly rotates clockwise. By this rotation, the heat-transferred ink ribbon 107 is taken up on the ribbon take-up reel 106.
[0026]
Power transmission mechanism to label peeling device
FIG. 3 is an enlarged cross-sectional side view showing the label peeling device and the power transmission mechanism to the unit, and FIG. 4 is a configuration diagram showing the power transmission mechanism of the unit in an extracted manner. The power transmission mechanism to the label peeling apparatus 200 will be described with reference to these drawings.
[0027]
The label peeling apparatus 200 according to the present embodiment is configured such that the driving peeling roller 202 rotates in response to a rotational driving force from a driving motor 108 provided in the printer main body 100. That is, the peeling roller driving gear 204 is attached to the rotating shaft 202 a of the driving peeling roller 202. The peeling roller driving gear 204 meshes with the second power transmission gear 114 on the printer main body 100 side when the label peeling device 200 is mounted on the printer main body 100.
[0028]
As described above, the rotational driving force of the drive motor 108 is transmitted to the second power transmission gear 114 via the power transmission belt 111 and the first power transmission gear 112 (see FIG. 2). Therefore, the rotational driving force of the drive motor 108 is transmitted to the peeling roller driving gear 204 that meshes with the second power transmission gear 114, and the driving peeling roller 202 is rotationally driven.
[0029]
As shown in FIG. 3, when the platen 102 rotates in the direction of feeding the label paper 1 (counterclockwise in FIG. 3), the second power transmission gear 114 rotates in the clockwise direction in FIG. 204 rotates counterclockwise in the figure, and the driving peeling roller 202 also rotates in the same direction. With this rotation, the mount 2 is pulled out via the peeling member 201.
As described above, the rotational driving force of the drive motor 108 is transmitted to the driving separation roller 202 by the meshing of the gears (gears), so that the rotational driving force can be reliably transmitted without causing any slip.
[0030]
Now, the circumferential speed v of the member is obtained by the product of the angular velocity ω and the member radius r (v = rω). The angular speed ratio between the platen 102 and the drive peeling roller 202 is determined by the gear ratio of the first power transmission gear 112, the second power transmission gear 114, and the peeling roller drive gear 204. Therefore, when the radii of the platen 102 and the drive peeling roller 202 are determined from the design specifications of the printer main body 100 and the label peeling device 200, the first power transmission gear 112, the second power transmission gear 114, And by setting the gear ratio of the peeling roller driving gear 204, the peripheral speed ratio between the platen 102 and the driving peeling roller 202 can be determined.
[0031]
In this embodiment, the gears of the first power transmission gear 112, the second power transmission gear 114, and the separation roller drive gear 204 are set so that the circumferential speed of the drive separation roller 202 is faster than the circumferential speed of the platen 102. The ratio is set.
By setting in this way, the pulling speed of the backing sheet 2 by the driving peeling roller 202 and the driven peeling roller 203 becomes faster than the conveying speed of the label sheet 1 by the platen 102. Thus, the label 3 can be reliably peeled off by the peeling member 201.
The difference between the conveyance speed and the pulling speed causes slippage between the driving peeling roller 202 and the driven peeling roller 203 and the mount 2.
[0032]
Further, in this embodiment, as shown in FIG. 4A, a one-way clutch 205 (clutch means) is interposed between the rotating shaft of the platen 102 and the first power transmission gear 112, and the label paper 1 is sent out. Only the rotational driving force in the direction (counterclockwise in FIG. 4A) is transmitted to the first power transmission gear 112. When the rotational driving force in the reverse direction (clockwise in FIG. 4A) is transmitted to the rotation shaft of the platen 102, the one-way clutch 205 slips and the rotational driving force is applied to the first power transmission gear 112. I don't get it.
[0033]
As described above, when the peripheral speed of the drive peeling roller 202 is higher than the peripheral speed of the platen 102, the rotational driving force in the returning direction (clockwise in FIG. 4A) is applied to the driving peeling roller 202. When transmitted, the mount 2 is returned to the printer main body 100 side at a speed faster than the return by the platen 102, so that the mount 2 is loosened (and thus clogged).
[0034]
Thus, by interposing the one-way clutch 205, the rotational driving force in the returning direction is not transmitted to the driving peeling roller 202, and the returning operation of the label paper 1 is possible without loosening the backing sheet 2.
With the return operation of the mount 2, the drive peeling roller 202 is rotated, and the rotation is transmitted from the second power transmission gear 114 to the first power transmission gear 112. The rotation is caused by the one-way clutch 205 idling. Absorb.
[0035]
The returning operation of the label sheet 1 is performed, for example, when a predetermined printing / conveying operation is completed. That is, the print head 101 stops the printing operation when printing on a predetermined number of labels 3, but the platen 102 continues the conveying operation until the last printed label 3 is sent to the label peeling device 200. For this reason, some blank labels 3 pass through the print head 101. When the next printing operation is started in this state, the blank label that has passed through the print head 101 is wasted. Therefore, after the printing / conveying operation is completed, a returning operation is executed to move the blank label to the upstream side of the print head 101.
[0036]
The one-way clutch 205 may be interposed between the second power transmission gear 114 and the rotating shaft 113 or between the peeling roller driving gear 204 and the rotating shaft 202a.
[0037]
FIG. 4B is a diagram showing another configuration example relating to the clutch means.
In the configuration shown in the figure, a pair of intermediate gears 300 and 301 are interposed between the second power transmission gear 114 and the peeling roller driving gear 204, and the one intermediate gear 300 and the peeling roller driving gear 204 are engaged and disengaged. It is free. When the drive motor 108 rotates in the direction of feeding the label paper 1, the intermediate gear 300 is engaged with the peeling roller driving gear 204, and the rotational driving force is transmitted to the driving peeling roller 202. On the other hand, when the drive motor 108 rotates in the direction to return the label paper 1, the intermediate gear 300 is separated from the peeling roller driving gear 204 so that the rotational driving force is not transmitted to the driving peeling roller 202.
[0038]
Detailed structure of label peeling device
Next, the detailed structure of the label peeling apparatus according to the present embodiment will be described with reference to FIGS. 3 and 5 to 10. FIG. 5 is an exploded perspective view of the label peeling device, and FIG. 6 is a perspective view showing a partially omitted assembly state of the label peeling device.
The label peeling apparatus 200 includes a frame, a peeling member 201, a holder 220, a driving peeling roller 202, and a driven peeling roller 203 as main component parts.
[0039]
The frame includes a front frame 211, side frames 212 and 213, and a back frame 214 (see FIG. 5). The front frame 211 has a window portion 211a. And the inside enclosed by each frame 211, 212, 213, 214 forms the hollow part 215 which uses this window part 211a as an opening (refer FIG. 3). An upper portion of the back frame 214 forms a flat guide surface 214 a, and a guide plate 216 is attached to the guide surface 214 a, and the inlet 217 for the label paper 1 is provided between the guide surface 214 a and the guide plate 216. Is formed (see FIG. 3). The label paper 1 conveyed from the printer main body 100 is sent into the hollow portion 215 from the introduction port 217.
[0040]
The peeling member 201 is configured by a roller member having a small-diameter round bar shape, and is rotatably supported by the side frames 212 and 213 near the opening of the introduction port 217 in the hollow portion 215.
[0041]
As shown in FIGS. 3 and 6, among the label sheets 1 conveyed from the printer main body 100, only the mount 2 is bent by the peeling member 201, and the conveyance direction is changed to a steep angle. As a result, the label 3 is peeled from the mount 2. Here, since the peeling member 201 guides the mount 2 while rotating, the frictional resistance between the peeling member 201 and the mount 2 is reduced, and the power loss is small.
[0042]
The drive peeling roller 202 is externally fixed to the rotary shaft 202a, and has a surface layer with a large friction coefficient such as synthetic rubber on the surface. The rotating shaft 202a of the driving peeling roller 202 is rotatably supported by the side frames 212 and 213. The central axis of the driving peeling roller 202 is arranged behind the back frame 214, but a part of the surface layer enters the hollow portion 215 from a notch (not shown) formed in the back frame 214, It contacts with a driven peeling roller 203 to be described later in the hollow portion 215 (see FIG. 3). The contact portion is located obliquely below and behind the peeling member 201, and the peeling rollers 202 and 203 are pulled out with the mount 2 interposed therebetween at this position.
[0043]
The holder 220 has support shafts 220a on both side surfaces, and the support shafts 220a are rotatably supported by the side frames 212 and 213 so that the holder 220 can be inserted into and removed from the window portion 211a of the front frame 211 into the hollow portion 215. ing. As shown in FIG. 3, the surface of the holder 220 is substantially flush with the front surface of the front frame 211 in a state where the holder 220 is accommodated in the hollow portion 215. Thus, the appearance quality is improved by making the front frame 211 and the surface of the holder 220 substantially flush with each other.
[0044]
As shown in FIG. 7, the driven peeling roller 203 is rotatably fitted on the shaft 203a. A shaft 203 a that rotatably supports the driven peeling roller 203 is supported by inserting both ends into a notch groove 221 formed in the holder 220. The opening edge of the notch groove 221 is crimped after the shaft 203a is inserted to prevent the shaft 203a from coming off. The shaft 203 a is slightly slidable in the notch groove 221.
[0045]
Further, a flat notch surface 203b is formed at the center portion of the shaft 203a so as to face the inner surface of the holder 220. Between the notch surface 203b and the inner surface of the holder 220, a coil spring 222 ( Urging means) is incorporated. The coil spring 222 biases the shaft 203a in the pushing direction.
[0046]
The driven peeling roller 203 attached to the holder 220 can be inserted into and removed from the window portion 211 a of the front frame 211 into the hollow portion 215 together with the holder 220. And in the hollow part 215, it arrange | positions in the position which contacts the surface layer of the drive peeling roller 202, and cooperates with the drive peeling roller 202 in this position, and clamps the base_sheet | mounting_paper 2 (refer FIG. 3, FIG. 6). At this time, the driven peeling roller 203 is pressed against the driving peeling roller 202 via the mount 2 by the urging force of the coil spring 222, so that the mount 2 can be securely held.
[0047]
FIG. 8 is a front view of the label peeling apparatus.
As indicated by the arrows in the figure, the holder 220 is slidable in the lateral direction (extending direction of the support shaft 220a), and the other member is attached by a spring member 218 (see FIG. 5) attached to one side frame 212. It is biased toward the side frame 213 side. As shown in FIG. 9, a locking groove 219 is formed in the other side frame 213. Furthermore, a locking claw 223 that engages with the locking groove 219 is formed on the side surface of the holder 220. When the holder 220 is inserted into the hollow portion 215, the locking claw 223 is engaged with the locking groove 219. And the insertion state is maintained.
[0048]
Further, as shown in FIG. 8, a concave groove 224 for operation is formed in the central portion of the upper edge of the holder 220. By sliding the holder 220 in the direction of the frame 212, the engagement state between the locking claw 223 and the locking groove 219 can be easily released and the holder 220 can be pulled out from the hollow portion 215. The sliding operation of the holder 220 can be easily performed by simply hooking the tip of the user's finger into the concave groove 224, for example. Therefore, even if the concave groove 224 is formed shallow (with a low height), the sliding operation is not hindered. As a result, the size and shape of the holder 220 are not restricted by the operation concave groove 224, and the holder 220 and thus the label peeling apparatus 200 can be miniaturized.
[0049]
As shown in FIG. 8, a label discharge port 230 is formed above the holder 220, while a mount discharge port 231 is formed below the holder 220.
[0050]
FIG. 10 is a diagram illustrating a method of loading label paper into the label peeling apparatus.
First, as shown in FIG. 5A, the base 2 of the label paper 1 sent out from the printer main body 100 through the inlet 217 with the holder 220 pulled out from the hollow portion 215 is removed by the peeling member 201. It is bent and guided to the mount discharge port 231. In the state where the holder 220 is pulled out from the hollow portion 215, the window portion 211a is opened, so that the mount 2 can be easily handled through the window portion 211a.
[0051]
Next, when the holder 220 is inserted into the hollow portion 215, the driven peeling roller 203 comes into pressure contact with the driving peeling roller 202 with the mount 2 interposed therebetween, as shown in FIG. When the printer main body 100 is driven in this state, the mount 2 is pulled out by the peeling rollers 202 and 203, and the label 3 is peeled off from the mount 2 at the curved portion by the peeling member 201 and discharged to the label discharge port 230. .
In this state, since the driven peeling roller 203 and the driving peeling roller 202 are housed in the hollow portion 215 of the frame, there is an opportunity for dust or the like floating outside to enter and adhere to the peeling rollers 203 and 202. There are few.
[0052]
The printer main body 100 can be mounted with a paper cutting unit (cutter) instead of the label peeling device 200 described above. Further, the printer main body 100 and the label peeling device 200 can be integrated.
[0053]
【The invention's effect】
As described above, according to the present invention, the driving peeling roller and the driven peeling roller are housed in the hollow portion of the frame, so that dust does not easily adhere to these peeling rollers, and thus the mount is stably held. Can be pulled out. In addition, since the driven peeling roller can be separated from the driving peeling roller and the opening on the front surface of the frame can be opened by rotating the holder, the label paper can be easily loaded from the opening.
