Description

  The present invention draws a label continuum from a roll body in which a strip-shaped label continuum is wound in a roll shape, performs printing on the label as necessary, and attaches the label separated from the label continuum to the adherend. The present invention relates to a portable label sticking machine used for sticking.

  For example, the portable label sticking machine described in Patent Document 1 holds a roll body in which a continuous label body in which a plurality of labels are temporarily attached on a mount (release paper) is wound in a roll shape, The label continuum is fed out from the roll body, the mount is turned at the label peeling portion, and the individual labels are peeled off from the mount so that they can be attached to the adherend. Therefore, after the label is attached, the mount is no longer necessary and is discarded, resulting in a waste of resources.

  Therefore, as described in Patent Document 2, a portable label sticking machine that can use a continuous label without a mount has been developed. By using a continuous label without a mount, resources are not wasted, and an environmentally friendly portable label applicator can be realized.

  By the way, the portable label sticking machine is provided with an operation lever that can be rotated within a predetermined angle range with respect to the grip provided on the housing, and the continuous label body is conveyed along with the rotation of the operation lever. The The operation lever is urged in a direction away from the grip by, for example, a coil spring.

  The operator holds the control lever together with the grip, pulls the control lever toward the grip against the biasing force of the coil spring, and then removes the force applied to the control lever to return the control lever to its original position. The label continuum is conveyed and a single-leaf label is placed on the sticking roller. Furthermore, when an operator presses the label on a sticking roller to a to-be-adhered body, a label is crimped | bonded and affixed on a to-be-adhered body.

  Here, the operating force required to pull the operating lever toward the grip and the speed at which the operating lever returns to the original position are specific to the model of the portable label applicator. The performance required for a portable label applicator is that the operating force required to pull the operating lever to the grip side is small, and the operating lever that has been pulled to the grip side in order to apply multiple labels continuously. The speed of returning to the original position is fast.

  However, if the coil spring is weakened to reduce the operating force, the return speed of the operating lever will be slow. On the other hand, in order to increase the return speed of the operating lever, it is necessary to strengthen the coil spring, which increases the operating force. Thus, decreasing the operating force and increasing the return speed of the operating lever are in a contradictory relationship. In addition, the appropriate operating force varies depending on the operator.

Japanese Utility Model Publication No. 55-150718 (Fig. 2) JP 2004-299757 A (paragraph 0003)

  Therefore, in view of the above points, the present invention reduces the operation force required to draw the operation lever to the grip side according to the operator who actually uses the portable label applicator and the usage environment, or It is an object of the present invention to provide a portable label sticking machine that can improve the speed at which an operation lever drawn toward the grip returns to the original position.

FIG. 1 is a side view showing a state in which one side plate of a portable label sticking machine according to an embodiment of the present invention is removed. The portable label sticking machine 1 draws the label continuous body 3 from the roll body in which the belt-like label continuous body 3 is wound in a roll shape, and prints the label 3a separated from the label continuous body 3 as necessary. The label 3a is used to attach the label 3a to an adherend (not shown), and is particularly applicable to a label continuum without a mount (release paper).

  For example, a continuous label without a mount is capable of separating individual labels by forming perforations (micro perforations) in the width direction at a predetermined interval on a belt-like label base material. Adhesive layers are provided in strips on both side edges, and a release agent layer (silicone oil layer, etc.) is provided in strips on a corresponding portion of the label substrate surface. The area between the agent layers is the printing area. Further, in order to accurately transfer the label continuum, one or a plurality of transfer slits having an oval shape may be formed in the center portion of the perforation in the label base material.

  As shown in FIG. 1, the portable label applicator 1 includes a pair of left and right side plates 2 (only one side plate is shown in FIG. 1) and a label continuous body 3 that are wound in a roll shape. A holding mechanism 4 that holds the rotated roll body, an operation lever 5, a platen unit 6, a printer 7, a label cutting mechanism 8, and a sticking roller 9 are included.

  The holding mechanism 4 rotates around a holder shaft 13 provided on the side plate 2 so as to be openable and closable with respect to the side plate 2 and a label holding provided inside the holder cover 14. A roll body including the shaft 15 and having the label continuous body 3 wound in a roll shape can be loaded and held on the label holding shaft 15.

  A pair of left and right side plates 2 is integrally provided with a grip 10 that can be gripped by an operator. The operation lever 5 is attached to the grip 10 so as to be rotatable around a lever shaft 11. An arbitrary urging member is provided between the operation lever 5 and the grip 10, and the operation lever 5 is located with respect to the grip 10 so that the operation lever 5 is in the released state as shown in FIG. 1. Is energized in a certain direction. As the biasing member, a coil spring, a torsion coil spring, or the like can be used. In the following, a case where the coil spring 12 is used will be described as an example.

  The operator grips the operating lever 5 together with the grip 10, pulls the operating lever 5 toward the grip 10 against the urging force of the coil spring 12, and then removes the force applied to the operating lever 5 to release the operating lever 5. By returning to the original position, the platen unit 6, the printer 7 and the label cutting mechanism 8 are driven. Thereafter, the operator uses the sticking roller 9 to perform an operation of sticking the single-leaf label 3a separated from the label continuous body 3 to the sticking object.

  The platen unit 6 is a transport mechanism that transports the label continuous body 3 in the direction of the affixing roller 9 as the operation lever 5 rotates. The label 3 a is sent out from the tip (left end in the figure), and the label is applied by the affixing roller 9. 3a can be affixed to a to-be-adhered body.

  FIG. 2 is an exploded perspective view of the platen unit shown in FIG. The platen unit 6 includes a platen frame 18, a transfer roller 19, and a pressing element 20, and the transfer roller 19 and the pressing element 20 can contact and separate from each other.

  The platen frame 18 is attached to the casing so as to be opened and closed with respect to the casing by rotating around the platen opening / closing shaft 21. A pair of engagement / disengagement rollers 26 are formed on the left and right sides of the front end side of the platen frame 18 so as to be able to engage / disengage with an opening / closing engagement / disconnection piece connected to an opening / closing knob 49 (FIG. 1). It has become. By operating the opening / closing knob 49 to open / close the entire platen unit 6 with respect to the housing, the label continuous body 3 shown in FIG. 1 can be inserted between the platen frame 18 and the transfer roller 19 and loaded. It becomes possible.

  The transfer roller 19 is attached to an opening formed in the platen frame 18 so as to be rotatable around a roller shaft 27, and rotates in contact with the surface (release agent layer) of the label continuous body 3, thereby holding mechanism 4. The label continuous body 3 is pulled out from the roll body held in (FIG. 1) and transferred.

  In the label continuous body 3, when one or a plurality of transfer slits are formed in the central portion of the micro perforation, the transfer rollers 19 are provided with one or more rows of transfer claws 33 at a predetermined pitch. It may be provided. These transfer claws 33 can be engaged with and disengaged from the transfer slit of the label continuous body 3. In the example shown in FIG. 2, a central circumferential groove 32 is formed between the circumferential portions provided with two rows of transfer claws 33, and a pair of left and right outer sides are formed on both sides of the circumferential portions. A circumferential groove 34 is formed.

  FIG. 3 is a perspective view of main parts of the operation lever and the platen unit shown in FIG. The operation lever 5 has a bifurcated yoke portion 5a on the tip side, and the printer 7 (FIG. 1) is attached to the yoke portion 5a. In addition, a transfer rotation claw 30 is attached to the connection shaft 29 of the connection arm 28 extending below the lever shaft 11 in the operation lever 5 so as to be able to reciprocate. The transfer rotation claw 30 is urged upward in the figure, and can be engaged with and disengaged from each of the plurality of transfer protrusions 31 provided radially on the side surface of the roller gear 25 in the transfer roller 19. Rotate. The operation lever 5 and the connecting arm 28 to the transfer projection 31 together with the grip 10 to the coil spring 12 shown in FIG. 1 constitute an operation mechanism that drives the platen unit 6 and the like as the operation lever 5 rotates.

  The platen unit 6 includes a drive gear 22, a driven gear 23, and a transfer endless belt 24 that is wound around the drive gear 22 and the driven gear 23. The driving gear 22 to the transfer endless belt 24 constitute a transfer mechanism that transfers the label continuous body 3 supplied from the transfer roller 19 in a predetermined direction. When the drive gear 22 engages with the roller gear 25 of the transfer roller 19, the transfer endless belt 24 is driven as the transfer roller 19 rotates. The transfer endless belt 24 contacts the back surface (adhesive layer) of the label continuum and transfers the label continuum. Instead of the driven gear 23, a cylindrical roller may be used.

  Here, when the operator holds the operation lever 5 together with the grip 10 (FIG. 1), the operation lever 5 rotates from the first position (lower side in the figure) to the second position (upper side in the figure). . As a result, the transfer rotation claw 30 connected to the connection arm 28 via the connection shaft 29 is another transfer protrusion 31 adjacent to the left side of the one transfer protrusion 31 that has been engaged so far. Will come into engagement.

  As the operation lever 5 rotates, the label cutting mechanism 8 (FIG. 1) cuts the label continuous body on the transfer endless belt 24 along the micro perforation, and separates the single leaf label from the label continuous body. To do. Further, the printer 7 (FIG. 1) attached to the yoke portion 5a performs imprinting on the single-leaf label separated from the label continuous body.

  On the other hand, when the operator releases the operation lever 5 from the grip, the operation lever 5 rotates from the second position to the first position, and is connected to the connection arm 28 via the connection shaft 29. The claw 30 pushes the engaged transfer protrusion 31. Thereby, the transfer roller 19 rotates around the roller shaft 27 by a predetermined angle, and the continuous label body is pulled out from the roll body held by the holding mechanism 4 (FIG. 1) and transferred. Further, since the drive gear 22 rotates via the roller gear 25, the transfer endless belt 24 is driven by a predetermined distance, and the label continuous body supplied from the transfer roller 19 is transferred in a predetermined direction.

  Since the back surface (adhesive layer) of the transferred label continuum is in contact with the surface of the transfer endless belt 24, the transfer endless belt 24 is made of silicone or fluorine rubber having non-adhesive properties. Alternatively, it is desirable to apply a release agent or the like to the surface of the transfer endless belt 24. Further, since the transfer endless belt 24 also serves as a cradle for the stamping operation on the label continuum by the printer 7, the transfer endless belt 24 is disposed inside the transfer endless belt 24 facing the printer 7 in the platen frame 18 (FIG. 2). A pressure receiving plate may be arranged.

  Referring to FIG. 2 again, the pressing element 20 includes an element frame 35, two pairs of upper, lower, left and right backup rollers 36, a pair of left and right backup rings 37 located inside the backup roller 36, a torsion coil spring 38, and left and right A pair of leaf springs 39 is included.

  The element frame 35 is provided on the support frame 41, a pair of left and right support frames 41 facing the circumference of the transfer roller 19, a pair of left and right widening frames 42 projecting outward from the support frame 41, and the support frame 41. And a pair of upper and lower rotating shafts 43 for mounting the backup roller 36 and the backup ring 37. The torsion coil spring 38 allows the transfer roller 19 to be separated from the pressing element 20 and allows a gap to be inserted between them so that the label continuous body can be inserted.

  FIG. 4 is a side view showing a state in which the platen unit is closed with respect to the housing. When the platen unit 6 is closed with respect to the housing, the transfer roller 19 and the pressing element 20 are pressed against each other. At that time, the backup roller 36 and the backup ring 37 (FIG. 2) press the label continuous body against the transfer roller 19 side.

  Here, since the backup roller 36 and the backup ring 37 are in line contact with the back surface (adhesive layer) of the label continuum, the adhesive force with the adhesive layer can be minimized and a pair of left and right leaf springs can be used. 39 allows pressing with a predetermined spring elasticity. Note that the backup roller 36 and the backup ring 37 are preferably made of silicone or fluorine rubber having non-adhesive properties, or have a release agent or the like applied to the surface.

  As the backup ring 37 rotates along the outer circumferential groove 34 formed in the transfer roller 19, the label continuous body is sandwiched between the transfer roller 19 and the pressing element 20. Further, the transfer claw 33 (FIG. 2) of the transfer roller 19 engages with the transfer slit from the surface side of the label continuous body, and the label continuous body is fed onto the transfer endless belt 24 by the rotation of the transfer roller 19.

  FIG. 5 is a side view showing a state in which the platen unit is opened with respect to the housing. When the platen unit 6 is opened with respect to the housing, the transfer roller 19 is separated from the pressing element 20, and a gap 40 for introducing the label continuous body 3 is formed therebetween.

  The widening frame 42 fixed to the support frame 41 is attached so as to be rotatable around an element shaft 47 provided on the outer wall surface of the platen frame 18, and the platen frame 18 is relatively moved with respect to the pressing element 20. It can be rotated.

  The torsion coil spring 38 is rotatably supported by a spring mounting shaft 44 provided on the outer wall surface of one support frame 41, and the first spring receiver 45 provided on the inner wall surface of the platen frame 18 and the one side Both ends of the platen frame 18 are urged against the pressing element 20 in a released state (FIG. 5) by contacting both ends with a second spring receiver 46 provided on the support frame 41.

  The leaf spring 39 is attached to the back surface of the support frame 41 opposite to the transfer roller 19 and cooperates with the torsion coil spring 38 by contacting the lever shaft 11 (FIG. 3) of the operation lever. Then, the platen frame 18 is biased with respect to the housing in a direction to be in a released state (FIG. 5).

  6 is an enlarged partial cross-sectional view showing a part of the portable label applicator shown in FIG. 1, and FIG. 7 is a part of the portable label applicator shown in FIG. 6 along the line VII-VII. It is sectional drawing. In the present embodiment, the biasing member is used to adjust the operation force required to pull the operation lever 5 toward the grip 10 according to the operator who actually uses the portable label applicator and the usage environment. A switching mechanism that can switch the urging force of the coil spring 12 is provided.

  The switching mechanism includes, for example, an eccentric cam 16 and a spring receiving plate 17 as shown in FIGS. 6 and 7, and a first end portion (upper side in the drawing) of the coil spring 12 is provided inside the grip 10. By selectively positioning, the urging force of the coil spring 12 can be switched.

  The eccentric cam 16 is rotatably supported by a guide portion 10a provided inside the grip 10, and includes an eccentric rotation shaft 16a and an outer peripheral surface including a plurality of plane portions having different distances from the center of the rotation shaft 16a. Have. The rotating shaft 16a has a pyramid or conical shape, and may be manufactured integrally with the eccentric cam 16, or may be manufactured separately from the eccentric cam 16 and inserted into a through hole of the eccentric cam 16. .

  The spring receiving plate 17 is disposed between the eccentric cam 16 and the first end of the coil spring 12, and serves as a positioning member that positions the first end of the coil spring 12 according to the rotational position of the eccentric cam 16. Function. A second end (lower side in the figure) of the coil spring 12 is inserted into a spring receiving groove 5 b formed in the operation lever 5.

  The rotating shaft 16a of the eccentric cam is formed with an adjustment hole 16b having a polygonal shape (such as a regular hexagon or a square) in a plane orthogonal to the axial direction, parallel to the axial direction. As shown in FIG. 7, the adjustment hole 16b may be formed over the entire axial direction of the rotating shaft 16a, or may be formed in a part of the rotating shaft 16a in the axial direction. Further, as shown in FIG. 7, in the grip 10, an opening 10b is formed at a position corresponding to the adjustment hole 16b of the rotating shaft of the eccentric cam.

  The position of the first end of the coil spring 12 is changed by inserting the operation pin 80 such as a hexagon wrench into the adjusting hole 16b of the rotating shaft of the eccentric cam and rotating the eccentric cam 16 through the opening 10b. can do. As shown in FIG. 6, the state of the eccentric cam 16 is stabilized by the urging force of the coil spring 12 when one flat surface portion included in the outer peripheral surface of the eccentric cam 16 is in contact with the spring receiving plate 17.

  In the case of the eccentric cam 16 shown in FIG. 6, the distance from the outer peripheral surface in contact with the spring receiving plate 17 to the center of the rotating shaft 16a can be set to any one of L1, L2, and L3 (L1 < L2 <L3).

  When the distance L1 is selected, the distance between the spring receiving plate 17 and the spring receiving groove 5b, that is, the attachment length of the coil spring 12 is maximized, and the urging force of the coil spring 12 is minimized. The operating force required to pull the lever 5 toward the grip 10 can be reduced.

  On the other hand, when the distance L3 is selected, the installation length of the coil spring 12 is minimized, the urging force of the coil spring 12 is maximized, and the operation lever 5 drawn toward the grip 10 returns to the original position. Speed (operation response) can be improved. This is suitable when a plurality of labels are continuously applied.

  Further, when the distance L2 is selected, the attachment length of the coil spring 12 becomes an intermediate value, and the urging force of the coil spring 12 becomes an intermediate value so that the operating force and the return speed are balanced. Can do.

Next, details of the label cutting mechanism will be described.
FIG. 8 is a perspective view of the operation lever and the label cutting mechanism shown in FIG. FIG. 9 is an exploded perspective view of the label cutting mechanism shown in FIG. FIG. 10 is an assembly view of the label cutting mechanism shown in FIG. As shown in FIG. 9, the label cutting mechanism 8 includes a cutting piece 51 and an interlocking mechanism 52.

  The cutting piece 51 cuts the label continuous body by reciprocating along the micro perforation and / or the transfer slit in the width direction of the label continuous body transferred on the transfer endless belt 24. Separate into single leaf labels. As a material of the cutting piece 51, it is desirable to have predetermined rigidity and non-adhesiveness. For example, a resin such as polyacetal (POM), or a silicone or a fluorine-based coating agent (release agent) is applied as necessary. A resin such as polycarbonate (PC) or acrylonitrile / butadiene / styrene (ABS) may be used.

  As shown in FIGS. 8 to 10, the interlocking mechanism 52 includes a vertical rail member (first rail member) 53, a connecting plate 54, a link bar 55, a burster bracket 56, and a horizontal rail member (second rail). Rail member) 57.

  The vertical rail member 53 is fixed to the inner wall surface of one side plate 2 (FIG. 1), and a vertical guide groove 58 is formed at the center thereof, and the connecting plate 54 can reciprocate up and down in the vertical guide groove 58. It is assembled to. The connection plate 54 has a connection pin 60 that is fitted in a yoke connection hole 59 formed in one yoke portion 5 a of the operation lever 5 shown in FIG. 8, and is linked to the vertical rail member 53 in conjunction with the operation lever 5. Reciprocate along. In addition, a link connecting hole 61 is formed in the connecting plate 54, and the connecting pin 62 of the link bar 55 is fitted into the link connecting hole 61 so that the driving force from the operation lever 5 (yoke portion 5a) is linked. It is transmitted to the bar 55.

  The link bar 55 is provided with a pair of left and right bracket connecting pins 63 at the end opposite to the connecting pin 62. The link bar 55 is connected between the connection plate 54 and the burster bracket 56, and is in a posture inclined with respect to the vertical rail member 53 and the horizontal rail member 57 in accordance with the reciprocation of the connection plate 54. The star bracket 56 is reciprocated.

  The burster bracket 56 includes a bracket body 64, a pair of left and right fulcrum pins 65, a pair of left and right posture regulating pins 66, and a pair of left and right elastic protrusions 67, and the transfer endless belt 24 (FIG. 2). It can reciprocate along the width direction. A cutting piece 51 is rotatably attached to the burster bracket 56.

  A bar connecting hole 68 is formed in the bracket main body 64 shown in FIG. 9, and the bracket connecting pin 63 of the link bar 55 is fitted into the bar connecting hole 68 so that the link bar 55 is connected to the bracket main body 64. . Therefore, by moving the link bar 55 in an inclined state with respect to the vertical rail member 53 and the horizontal rail member 57, the cutting piece 51 can be reciprocated in the width direction of the label continuous body together with the burster bracket 56.

  The horizontal rail member 57 is disposed at a right angle to the vertical rail member 53 along the width direction of the transfer endless belt 24 so as to be positioned above the transfer endless belt 24 (FIG. 2). The horizontal rail member 57 is formed with a guide window 69 for guiding the fulcrum pin 65 and the posture regulating pin 66 of the burster bracket 56 on the left and right wall surfaces.

  The guide window 69 guides the burster bracket 56 in the width direction of the label continuous body and restricts the operation range thereof. The fulcrum pin 65 and the attitude regulating pin 66 are movable along a guide window 69 formed in the horizontal rail member 57. The posture regulating pin 66 is in contact with or separated from the upper inner wall surface 69a or the lower inner wall surface 69b of the guide window 69, and the posture of the burster bracket 56, that is, the contact / separation posture (pressing and separation) of the cutting piece 51 with respect to the label continuous body. regulate. Also, as shown in FIG. 10, a posture control window 70 is formed on the bottom surface of the horizontal rail member 57 along the width direction of the transfer endless belt 24 (FIG. 2).

  FIG. 11 is a side view of the cutting piece and the interlocking mechanism in a state where the operation lever is gripped and the cutting of the label continuous body is started. 12 is a diagram for explaining the cutting operation of the cutting piece and the interlocking mechanism shown in FIG. 11, FIG. 12 (A) is a side view of the main part of the cutting piece and the interlocking mechanism, and FIG. It is an enlarged front view of a cutting piece and a transfer endless belt. FIG. 13 is a view for explaining the return operation of the cutting piece and the interlocking mechanism shown in FIG. 11, FIG. 13A is a side view of the main part of the cutting piece and the interlocking mechanism, and FIG. It is an enlarged front view of a cutting piece and a transfer endless belt.

  In the state where the operation lever 5 is released from the grip 10 shown in FIG. 1, the coupling plate 54 is connected to the vertical rail member 53 in the interlocking mechanism 52 shown in FIGS. 9 and 10 by the force of the coil spring 12 pulling up the yoke portion 5 a. It is located at the highest position in the guide groove 58. Accordingly, the Burster bracket 56 connected to the connecting plate 54 via the link bar 55 rotates slightly counterclockwise around the fulcrum pin 65, and the posture regulating pin 66 is moved to the guide window 69 of the lateral rail member 57. The cutting piece 51 is in contact with the upper inner wall surface 69a and is slightly away from the surface of the label continuum.

  When the operation lever 5 is gripped together with the grip 10, the driving force (arrow A1) from the yoke portion 5a is transmitted from the connecting plate 54 to the link bar 55 as shown in FIG. As a result, the attitude regulating pin 66 is slightly rotated clockwise around the fulcrum pin 65 (arrow A2) and comes into contact with the lower inner wall surface 69b. Therefore, the cutting piece 51 is lowered to a level position where the cutting piece 51 can enter below the continuous label body 3 on the transfer endless belt.

  At this time, as shown in FIG. 11, the cutting piece 51 is located slightly to the left of the left edge portion of the label continuous body 3 in the drawing. By further gripping the operation lever 5, the cutting piece 51 moves to the right from this state, so that the cutting piece 51 cuts into the side surface of the label continuous body 3.

  When the operation lever 5 is further gripped, the connection plate 54 is further lowered by transmission of the driving force from the operation lever 5, and the driving force is transmitted to the burster bracket 56 via the link bar 55. Accordingly, as shown in FIG. 12, the Burster bracket 56 moves toward the right end of the guide window 69 of the lateral rail member 57, and the cutting piece 51 moves along the transverse recess 24 a of the transfer endless belt 24. .

  The circumferential tip 51a of the cutting piece enters the transverse recess 24a of the transfer endless belt 24 while applying a predetermined pressing force to the edge portion of the label continuous body 3, and extends to the edge portion of the label continuous body 3. The label continuum 3 is broken sequentially from the end of the existing perforation. As a result, the label continuous body 3 can be cut with a relatively small force to separate the label continuous body 3 into single-leaf labels.

  Since the transverse recess 24a of the transfer endless belt 24 is formed relatively thin in accordance with the shape of the circumferential tip 51a of the cutting piece 51, the circumferential tip 51a and the micro perforation of the label continuous body 3 Even if the relative position slightly deviates, the micro perforation of the label continuous body 3 or the vicinity thereof can enter the transverse recess 24a. Therefore, the cutting operation as described above can be performed accurately.

  The cutting piece 51 completes the cutting of the label continuous body 3 with the operating lever 5 fully gripped. Next, when the operation lever 5 is released, the link bar 55 is pulled up by the connecting plate 54 by the pulling force that the coil spring 12 (FIG. 1) acts on the connecting plate 54. Thereby, the cutting piece 51 starts to separate from the label continuous body 3.

  As shown in FIG. 13, the Burster bracket 56 rotates counterclockwise around the fulcrum pin 65, the attitude regulating pin 66 abuts on the upper inner wall surface 69a of the guide window 69, and the cutting piece 51 becomes the label continuous body. 3 is lifted from the surface of 3. As the operating lever 5 is released, the connecting plate 54 and the link bar 55 return upward, and the burster bracket 56 returns to its original position.

  In the process of releasing the operation lever 5, the continuous label body 3 is transferred by a predetermined angle by the transfer roller 19 shown in FIG. 2, and the continuous label body 3 is transferred by a predetermined distance by the endless belt 24 for transfer. . Therefore, during the movement of the label continuum 3, the cutting piece 51 does not contact or interfere with the label continuum 3 so that the transfer of the label continuum 3 is not hindered.

  However, due to a slight timing difference between the cutting operation and the transfer operation of the label continuous body 3 due to the gripping and releasing of the operation lever 5, the cutting piece 51 is engaged with the transverse recess 24a of the label continuous body 3 or the transfer endless belt 24. Even if the label continuum 3 is transferred in a state where the tape is continuous, the taper shape of the circumferential tip 51a of the cutting piece and the taper shape of the transverse recess 24a of the transfer endless belt 24 are almost the same inclined surface. (See FIG. 13B), the cutting piece 51 is separated upward from the transverse recess 24a of the transfer endless belt 24 without stopping the transfer of the label continuous body 3. can do.

  Referring again to FIG. 1, the printer 7 is attached to the tip end side of the bifurcated yoke portion 5 a of the operation lever 5. When the operator holds the operation lever 5 together with the grip 10, the printer 7 also Rotate. As a result, ink is applied to the type portion 7a of the printer 7 by the ink roller 48, and the type portion 7a comes into contact with the label 3a which is attached to the upper surface of the transfer endless belt 24 and transferred to the label 3a. Predetermined information is printed. Here, the printer 7 and the ink roller 48 constitute a printing mechanism that performs printing on the label 3 a on the transfer endless belt 24. In addition, when using the label continuous body 3 which has already been printed, it is not necessary to print on the label 3a, and therefore printing can be omitted by removing the printer 7 or the like.

  The pasting roller 9 is located at the lower end of the front end of the casing of the portable label pasting machine 1 (lower left end in FIG. 1), and a part of its circumference is exposed to the outside of the casing. The endless belt 24 comes into contact with the label 3a conveyed to the tip end portion of the platen unit 6. When the operator performs a pasting operation of pressing the label 3a on the pasting roller 9 against the body to be pasted, the label 3a is pressed and pasted to the body to be pasted by the pasting roller 9.

  In the above embodiment, although the case where the label continuous body without a mount was used was demonstrated, this invention is applicable also to the portable label sticking machine which uses the general label continuous body with a mount. .
