Description

The present invention relates to a mountless label cutting apparatus and a mountless label cutting method of a portable mountless label sticking machine, and in particular, a belt-like mountless label is loaded and transported to perform a sticking operation on a desired adherend. The present invention relates to a boardless label cutting device and a boardless label cutting method of a portable boardless label sticking machine.

2. Description of the Related Art Conventionally, a label is attached to various products and other objects to be attached using a portable label applicator, and the price of the product and other necessary information are displayed.
When using this portable label applicator, in a state where the label is rolled up, it is loaded and held in a holder such as a paper holder in the portable label applicator, and the label is fed out from the paper holder into a belt shape. Insert into a portable label applicator and transfer or print.

As a label to be loaded into the portable label applicator, it has a strip-shaped label base material, an adhesive layer provided on the back surface of the label base material, and a release agent layer provided on the surface of the label base material, There is a non-mounting label without a mount, and the non-mounting label can contribute to resource saving because it does not have a mount.
However, since the label without mount is not backed by the mount, it is necessary to cut the label at a predetermined pitch to make a single-leaf label piece.
That is, in the portable boardless label sticking machine used by loading the label without board, a mechanism for cutting the strip-like boardless label to be transferred into the machine at a predetermined pitch is required.

However, the conventional portable baseless label pasting machine employs, for example, a pair of tempered cutter blades as the cutting mechanism, and sandwiches the baseless label from the front and back surfaces.
In such a cutting structure, the cutter blade itself is expensive, requires a large force for pinching, requires a strong body frame that supports the cutter blade, and is therefore heavy and expensive. Further, there are various problems such as that the cutter blade itself is not safe.

In order to solve such various problems, it is conceivable to cut the baseless label by pushing it back and forth in the width direction of the baseless label without using a cutter blade.
However, in this measure, it is not desirable from the viewpoint of cutting performance that the cutting force differs between the start of cutting and the end of cutting of the label without a mount. A structure for maintaining and improving the cutting performance by making the force as uniform as possible is required.

    In addition, when pasting a label on which sales promotion information or advertisement information is printed in advance, the label can be pasted only by operating the operation lever without providing a printing unit. Even in the case of a labeling machine without a mount, there is a similar problem with the cutting mechanism for the label without a mount.

However, the driving groove 63 includes a rotation driving groove 63A on the base end side and an inclined driving groove 63B continuous with the rotation driving groove 63A.
The rotation drive groove 63A is a groove region where the plate interlocking pin 64 is engaged when the operation lever 5 is released from the released state. When the operation lever 5 is further gripped, the link bar 56 is connected via the plate interlocking pin 64. A first posture in which the star bracket 57 can be pressed against the transfer endless belt 23 and the cutting piece 51 can be pressed against the surface of the non-mounting label 3 (FIGS. 7, 10, 11, 12 and later). ), And a second posture (FIGS. 8, 9, 13, 14, and later) that can release the pressure on the non-mounting label 3 by the cutting piece 51 so that the posture can be changed. .
The inclined driving groove 63B further drives the link bar 56 via the plate interlocking pin 64 when the operation lever 5 is further gripped, and the cutting piece 51 is in a state where the burster bracket 57 takes the first posture. In the groove region for performing the cutting operation of the label 3 without the mount, the link bar 56 is inclined with respect to the surface of the transfer endless belt 23 in the direction of driving the cutting piece 51 of the burster bracket 57 in the forward cutting operation. And formed.

    As described above, the link bar 56 has the plate interlocking pin 64 that engages with the driving groove 63 of the driving plate 55 and is movable along the driving groove 63, and responds to the reciprocation of the connecting plate 54. A bracket connecting pin that operates and is positioned in an inclined posture between the vertical rail member 53 and the horizontal rail member 58, and is connected to the Burster bracket 57 at the end opposite to the plate interlocking pin 64. 65 is provided.

The burster bracket 57 is connected to the link bar 56 via a bracket connection pin 65 and can reciprocate in the lateral rail member 58 along the width direction of the transfer endless belt 23, and the cutting piece 51 It is attached rotatably, and has a bracket body 66, a pair of left and right fulcrum pins 67, a pair of left and right attitude regulating pins 68, and a pair of left and right elastic protrusions 69.
A bar connecting hole 70 is formed in the bracket main body 66, and the bracket connecting pin 65 of the link bar 56 is fitted into the bar connecting hole 70 to connect the link bar 56 to the bracket main body 66. Therefore, by operating the link bar 56 in an inclined state between the vertical rail member 53 and the horizontal rail member 58, the burster bracket 57 (cutting piece 51) can be reciprocated in the width direction of the non-mounting label 3. it can.

The horizontal rail member 58 guides the burster bracket 57 in the width direction of the non-mounting label 3 and restricts its operating range, and is positioned above the endless belt 23 for transfer at a right angle to the vertical rail member 53. Thus, this is arranged along the width direction of the transfer endless belt 23, and the guide window 71 through which the fulcrum pin 67 and the attitude regulating pin 68 of the burster bracket 57 are guided is formed in the left and right side wall surfaces.
That is, the fulcrum pin 67 and the posture regulating pin 68 are movable along the guide window 71 formed in the horizontal rail member 58.
The attitude regulating pin 68 contacts and separates the upper inner wall surface 71A and the lower inner wall surface 71B of the guide window 71 to regulate the attitude of the burster bracket 57 or the contact / separation (pressing and separating) posture of the cutting piece 51 with respect to the non-mounting label 3. To do.

Further, as shown in the horizontal sectional views of FIGS. 9 to 14, a posture control window 72 is formed in the bottom surface of the horizontal rail member 58 along the width direction of the transfer endless belt 23.
FIG. 9 is a side view of the cutting piece 51 and the interlocking mechanism 52 in the released state of the operation lever 5 and a horizontal sectional view of the bottom surface portion of the lateral rail member 58.
FIG. 10 shows the cutting piece 51 and the interlocking mechanism in a state where the operation lever 5 and the grip 10 are slightly gripped and the cutting piece 51 of the Burster bracket 57 is in the first posture capable of pressing the label 3 without the mount. FIG. 52 is a side view of FIG. 52 and a horizontal sectional view of the bottom surface portion of the horizontal rail member 58.
FIG. 11 is a side view of the cutting piece 51 and the interlocking mechanism 52 in the state where the operation lever 5 and the grip 10 are gripped slightly further and the cutting of the label 3 without mount is started, and the bottom surface portion of the horizontal rail member 58. FIG.
FIG. 12 is a side view of the cutting piece 51 and the interlocking mechanism 52 in the state where the operation lever 5 and the grip 10 are completely grasped and the cutting of the non-mounting label 3 by the cutting piece 51 is completed. It is a horizontal sectional view.
FIG. 13 is a side view of the cutting piece 51 and the interlocking mechanism 52 in a state where the operation lever 5 is released and the cutting piece 51 starts to return to the original position, and a horizontal sectional view of the bottom surface portion of the lateral rail member 58.
FIG. 14 is a side view of the cutting piece 51 and the interlocking mechanism 52 and a horizontal sectional view of the bottom surface of the lateral rail member 58 in a state where the operation lever 5 is released and the cutting piece 51 returns to the original position.

In particular, as shown in the horizontal sectional view of FIG. 9, the attitude control window 72 includes a non-brake window 72A formed on the side rail member 58 on the cutting start position side of the burster bracket 57 in the width direction of the transfer endless belt 23. The brake window 72C is formed so as to extend to the cutting end position side of the burster bracket 57 continuously to the non-brake window 72A via the protrusion contact stepped portion 72B which is a mutual boundary.
The cutting piece 51 and the elastic protrusion 69 positioned below the Burster bracket 57 reciprocate toward the attitude control window 72 (the non-brake window 72A and the brake window 72C) and are separated from the non-brake window 72A and the brake window 72C. And will be in sliding contact.
However, the width H of the free state facing the non-brake window 72A, ie, the width W1 of the non-brake window 72A and the width of the brake window 72C, is the state in which the left and right elastic protrusions 69 are not assembled to the attitude control window 72. Between W2 (W2 <H <W1).
The elastic projection 69 of the burster bracket 57 is separated from and slidably contacted with the wall surface of the attitude control window 72. In particular, as shown in the horizontal sectional views of FIGS. When the abutment 69 abuts against the projection abutting step 72B, the elastic projection 69 serves as a fulcrum of the entire burster bracket 57 to change the posture of the burster bracket 57, and the cutting piece 51 can cut the mountless label 3. 1 is rotated (described later).

    In particular, as shown in FIG. 5, a label pressing member 73 is fixed to the bottom of the horizontal rail member 58, and a label pressing plate 74 is attached to the bottom of the label pressing member 73. The transferred label 3 without the mount 3 can be pressed against the upper surface of the endless belt 23 by the bottom surface of the label pressing plate 74 to prevent the label 3 without the mount from being lifted. This ensures the cutting action.

In particular, as shown in FIGS. 7 (2) and 8 (2), the endless belt 23 for transfer has a transverse recess 23A in which the circumferential tip 51A of the cutting piece 51 can be pushed so as to tear the label 3 without the mount. The cross-sectional uneven shape formed on the upper surface is exhibited.
Further, the taper shape of the circumferential tip 51A is made equal to the taper shape of the transverse recess 23A in the transfer endless belt 23.

In particular, as shown in FIG. 6, the control plate 59 is attached to the horizontal rail member 58 and the vertical rail member 53 at right angles to each other, and a pair of left and right shaft ends of the plate interlocking pin 64 of the link bar 56. A control groove 75 that is movable by engaging the portion 64B is formed.
The control groove 75 has a rotation control groove 75A on the vertical rail member 53 side and a parallel control groove 75B continuous to the rotation control groove 75A.
The rotation control groove 75A is a groove region where the plate interlocking pin 64 engages with the rotation driving groove 63A of the driving groove 63 in the driving plate 55 when the operation lever 5 is released from the released state, and the plate interlocking pin 64. A first posture (FIG. 7) and a cutting piece in which the link bar 56 presses the cutting piece 51 against the endless belt 23 for transferring the burster bracket 57 against the surface of the label 3 without the mount. It is made rotatable so that the posture can be changed to the second posture (FIG. 8) in which the pressure on the label 3 without the mount by 51 is released.
The parallel control groove 75B is a groove region in which the link bar 56 is further driven via the plate interlocking pin 64 when the operation lever 5 is further gripped, and the cutting operation 51 performs the cutting operation of the label 3 without the mount. A bar 56 is formed in parallel with the surface of the transfer endless belt 23 in a direction for driving the cutting piece 51 of the burster bracket 57 in the forward cutting operation.

Thus, the interlocking mechanism 52 moves the plate interlocking pin 64 of the link bar 56 in parallel along the surface of the transfer endless belt 23 along the control groove 75 of the control plate 59 during the forward cutting operation of the cutting piece 51. The cutting frame 51 can be pressed against the label without a mount with a predetermined pressing force as possible, and the cutting frame 51 can be separated from the label without a mount when the cutting frame 51 is moved backward and non-cut.
That is, by gripping the operation lever 5, the plate interlocking pin 64 of the link bar 56 is slid into the driving groove 63 of the driving plate 55 in the interlocking mechanism 52 and the link bar is inserted into the control groove 75 of the control plate 59. 56 plate interlocking pins 64 are slid in parallel with the surface of the endless belt 23 for transfer, and the cutting piece 51 of the burster bracket 57 is moved forward along the horizontal rail member 58 in the width direction of the label without a mount. The label without the mount is cut in the width direction of the label without the mount with the cutting lever 51 of the burster bracket 57 separated from the label without the mount via the link bar 56 in the interlocking mechanism 52 by cutting the label without the mount. Return to the original position.

In the portable mountless label sticking machine 1 and the mountless label cutting device 9 having such a configuration, the opening / closing knob 26 is operated to engage the engagement / disengagement recess 28 </ b> A and the engagement / disengagement roller 25. When the platen unit 6 is opened with respect to the side plate 2 by releasing the engagement, the torsion coil spring 40 receives the reaction force from the lever shaft 11 or the side plate 2 via the plate spring 41 and the torsion coil spring 40 is moved from the pressing element 19 to the transfer roller 18. The portions are separated from each other, and the gap 42 is formed with the maximum opening between the transfer roller 18 and the pressing element 19.
Accordingly, a portion of the gap 42 formed between the central circumferential groove 34, the transfer claw 35 and the outer circumferential groove 36 in the circumferential portion of the transfer roller 18, and the backup roller 38 and backup ring 39 of the pressing element 19. The leading portion of the label 3 without the mount can be inserted.
Next, the platen unit 6 is closed to the state shown in FIG. 1, the engagement / disengagement recess 28 </ b> A of the opening / closing engagement / disengagement piece 28 is engaged with the engagement / disengagement roller 25, and the operation lever 5 and the grip 10 are gripped several times. Then, if the transfer claw 35 is engaged with the transfer slit 3A of the label 3 without mount, the transfer of the label 3 without mount is enabled and the loading is completed.

In the portable mountless label pasting machine 1 with the platen unit 6 closed, the printer 7 prints on the mountless label 3 on the transfer endless belt 23 by grasping the operation lever 5 and the grip 10. At the same time, the transfer rotation claw 32 moves from the transfer protrusion 33 of the roller gear 24 in the transfer roller 18 to the adjacent transfer protrusion 33 side (on the left side in FIG. 3). The moving claw 32 rotates the transfer protrusion 33 forward (in the right direction in FIG. 3), and the transfer roller 18 is rotated at a predetermined pitch to transfer the mountless label 3.
Further, the drive gear 21 engaged with the transfer roller 18 rotates to rotate the transfer endless belt 23 so that the non-mounting label 3 on the upper surface thereof can be fed out of the side plate 2.
The label piece 3B of the mountless label 3 fed to the outside of the side plate 2 at the leading end (downstream side) of the transfer endless belt 23 can be attached to a predetermined adherend by the attaching roller 8.

With the printing and transfer of the label 3 without the mount as described above, the label 3 without the mount is cut by the label cutting device 9 without the mount by holding the operating lever 5 and the grip 10.
The cutting process of the non-mounting label 3 by the non-mounting label cutting apparatus 9 will be described below with reference to FIGS.
As shown in FIG. 9, in a state where the operation lever 5 is released, the connecting plate 54 of the interlocking mechanism 52 of the vertical rail member 53 is pulled by the pulling force from the yoke portion 5 </ b> A of the operation lever 5 by the coil spring 12 (FIG. 3). It is located at the top in the vertical guide groove 60.
Therefore, the burster bracket 57 is slightly rotated counterclockwise around the fulcrum pin 67 from the connecting plate 54 and the driving plate 55 via the link bar 56, and the attitude regulating pin 68 is a guide for the lateral rail member 58. As a result of the contact with the upper inner wall surface 71A of the window 71, as shown in FIG. 8, the bracket body 66 is in a state where the cutting piece 51 is slightly separated from the surface of the label 3 without the mount (second posture). )It is in.
Further, as shown in the horizontal sectional view of FIG. 9, in the attitude control window 72 of the lateral rail member 58, the elastic protrusion 69 of the burster bracket 57 is positioned in the non-brake window 72A and is in the protrusion contact step 72B. The cutting piece 51 faces a portion of the brake window 72C while slightly contacting.

As shown in FIG. 10, the operating lever 5 and the grip 10 are gripped, and the driving force (arrow A1) from the yoke portion 5A is transmitted from the connecting plate 54 to the link bar 56. The link bar 56 is controlled by the control plate 59. , The posture regulating pin 68 is slightly rotated clockwise around the fulcrum pin 67 (arrow A2) and abuts against the lower inner wall surface 71B, so that the cutting piece 51 is placed on the transfer endless belt 23. It goes down to a level position where it can enter the transverse recess 23A below the label 3 without mount (first posture).
However, as shown in a partially enlarged view in the horizontal sectional view of FIG. 10, the burster bracket 57 is slightly retracted to the retracted position (left position in FIG. 10) once in the attitude control window 72. The protrusion 69 is slightly separated from the protrusion contact step 72B.
By further slight gripping of the operating lever 5 and the grip 10 (arrow A3, FIG. 11), as shown in the horizontal sectional view of FIG. 11, the elastic protrusion 69 is brought into contact with the protrusion between the non-brake window 72A and the brake window 72C. The burster bracket 57 (bracket main body 66) surely shifts to the first posture with the fulcrum pin 67 as a fulcrum, contacting the stepped portion 72B, and the cutting piece 51 moves in the posture control window 72, and the mount None The label 3 is ready to be cut.
That is, as shown in the horizontal sectional view of FIG. 11, the cutting piece 51 is located slightly to the left of the left edge in the figure of the label 3 without mount, and further grips the operation lever 5 and the grip 10. As a result, the cutting piece 51 moves to the right from this state, and as a result, the cutting piece 51 cuts from the side surface of the non-mounting label 3.

As shown in FIG. 12, the connection plate 54 is further lowered by transmission of the driving force from the operation lever 5 by further gripping the operation lever 5 and the grip 10 (arrow A4), and the Burster bracket 57 is connected via the link bar 56. Moves to the end of the guide window 71 of the horizontal rail member 58, the cutting piece 51 moves along the transverse recess 23A of the transfer endless belt 23 (arrow A5), and the transfer slit 3A and the sewing machine of the label 3 without mount The perforation 3C is positioned so that the circumferential tip 51A enters the transverse recess 23A of the transfer endless belt 23 with a predetermined pressing force at the portion of the mesh 3C (FIG. 3), and in particular, the cuts face both ends. As a result of breaking in order from the end of the sheet, the non-mounting label 3 is cut into the single-leaf label piece 3B with a relatively small force.
Since the transverse recess 23A of the transfer endless belt 23 is formed relatively thin in accordance with the circumferential tip 51A of the cutting piece 51, the circumferential tip 51A, the transfer slit 3A and the perforation 3C are formed. Even if the relative position is slightly deviated, the transfer slit 3A and the perforation 3C or the vicinity thereof can enter the transverse recess 23A, and the above-described cutting action can be performed accurately.
11 and 12, the elastic protrusion 69 faces the brake window 72C of the attitude control window 72 and slides on the wall surface with a predetermined friction force during the cutting operation described above. However, since the gripping force by the operation lever 5 and the grip 10 is much larger, the posture of the burster bracket 57 itself, that is, the level of the cutting piece 51 can be kept constant, and the cutting action itself is stabilized. When the cutting is completed, it is positioned on one side of the attitude control window 72 (the right brake window 72C in FIG. 12) and enters with a predetermined frictional force.

As described above, in the process from the start to the end of cutting of the non-mounting label 3 by the cutting piece 51, the plate interlocking pin 64 of the link bar 56 that has moved the cutting piece 51 is connected to the driving groove 63 ( While receiving the driving force from the inclined driving groove 63B), the track is regulated in parallel with the transfer endless belt 23 by the control groove 75 (parallel control groove 75B) of the control plate 59, so that the transfer endless The change in the inclination angle between the start of cutting of the link bar 56 with respect to the label 3 without mount on the belt 23 and the end of cutting can be minimized, and the component force of the cutting force applied to the cutting piece 51 (in the direction of label 3 without mount) It is possible to reduce the change in the vector force) and make it almost constant.
Thus, the cutting piece 51 moving in the width direction of the transfer endless belt 23 via the link bar 56 and the burster bracket 57 applies a substantially equal cutting force to the label 3 without mount from the start of cutting to the end of cutting. Can be granted.

    As shown in FIG. 12, in a state where the operation lever 5 and the grip 10 are completely gripped, the cutting piece 51 cuts the mountless label 3 and waits for the next operation lever 5 to be released.

As shown in FIG. 13, when the operation lever 5 is released, the cutting piece 51 is separated from the non-mounting sheet label 3 via the interlocking mechanism 52 by the pulling force (arrow A6) acting on the connecting plate 54 by the coil spring 12. Begin to.
Specifically, when the link bar 56 is pulled up via the connecting plate 54, the elastic protrusion 69 is stopped in the brake window 72C with a predetermined frictional force as shown in the horizontal sectional view of FIG. The Burster bracket 57 (bracket body 66) itself rotates counterclockwise around the fulcrum pin 67 (arrow A7), and is pulled up slightly from the bar connecting hole 70 (bracket connecting pin 65). The posture regulation pin 68 comes into contact with the upper inner wall surface 71A of the guide window 71, so that the cutting piece 51 is lifted from the surface of the non-mounting label 3 (see also the second posture, FIG. 8).
Therefore, when the operation lever 5 is released, as described above, the non-mounting label 3 is transferred by the transfer roller 18 at a predetermined pitch, and the non-mounting label 3 is transferred on the transfer endless belt 23 by the same pitch. In the middle, that is, the label 3 itself without the mount is moving on the transfer endless belt 23, and during this movement, the cutting piece 51 does not contact or interfere with the label 3 without the mount, and the mount The transfer of the none label 3 on the transfer endless belt 23 is prevented from being hindered.
However, due to a slight timing difference between the cutting action and the transfer action of the mountless label 3 due to the gripping and releasing of the operation lever 5, the cutting piece 51 is engaged with the mountless label 3 or the transverse recess 23A of the transfer endless belt 23. Even if the non-mounting label 3 is transported in the state where it is left, the tapered shape of the circumferential tip 51A of the cutting piece 51 and the tapered shape of the transverse recess 23A of the transporting endless belt 23 are substantially the same. Therefore, the cutting piece 51 can be separated upward from the transverse recess 23A without stopping the transfer of the non-mounting label 3 (see FIG. 8 (2)).

As shown in FIG. 14, with the release of the operation lever 5, the connecting plate 54 and the link bar 56 return upward (arrow A8), and the burster bracket 57 returns to the original position (arrow A9).
In the transition from the state shown in FIG. 13 to the state shown in FIG. 14, the elastic protrusion 69 engaged with the wall surface of the non-brake window 72A with a predetermined frictional force as shown in the horizontal sectional view of FIG. By the biasing force of the coil spring 12 much larger than the frictional force, the brake window 72C can be easily moved to the non-brake window 72A on the opposite side (left side in the figure).
That is, due to the pulling force by the coil spring 12, the posture restriction pin 68 of the burster bracket 57 is slightly lifted upward via the link bar 56, and the posture restriction pin 68 contacts the upper inner wall surface 71 </ b> A of the guide window 71. The Burster bracket 57 returns to the original position while being slightly inclined upward, and the next operation lever 5 and grip 10 are held.

In this way, the interlocking mechanism 52 can cut the mountless label 3 when the operation lever 5 is gripped, and can transfer the mountless label 3 on the transfer endless belt 23 when the operation lever 5 is released.
Further, the interlocking mechanism 52 can press the cutting piece 51 against the label 3 without backing paper with a predetermined pressing force during the forward cutting operation of the cutting piece 51, and the cutting piece 51 when the cutting piece 51 does not move backward. Can be separated from the label 3 without mount.
In other words, the cutting piece 51 can be moved forward in the width direction of the non-mounting label 3 via the interlocking mechanism 52 by gripping the operation lever 5, and the non-mounting label 3 can be cut. At the time of reciprocation along the width direction of the transfer endless belt 23 by the interlocking mechanism 52, the first posture (FIG. 7) of pressing the cutting piece 51 against the surface of the label 3 without mount is taken.
When the operation lever 5 is released and the cutting frame 51 is moved back in the width direction of the non-mounting label 3 via the interlocking mechanism 52 and returned to the original position, the burster bracket 57 is used to remove the non-mounting label from the cutting frame 51. The posture is changed to the second posture (FIG. 8) for releasing the pressure on 3.

As described above, according to the label cutting device 9 without mount, the cutting piece 51 is moved in the width direction of the label 3 without mount and is inserted into the transverse recess 23A on the endless belt 23 for transfer. Since the transfer slit 3A and the perforation 3C are torn, without using a cutter blade as in the prior art, it is possible to safely and easily cut the label 3 without the mount with a relatively small force, The burden on the entire body frame can also be reduced.
Further, during the cutting operation of the non-mounting label 3 by the cutting piece 51, the result is that the plate interlocking pin 64 of the link bar 56 restricts the movement trajectory in parallel by the parallel control groove 75B in the control groove 75 of the control plate 59. Since the cutting force by the cutting piece 51 is evenly applied to the surface of the transfer endless belt 23 in the width direction, the pressing force of the cutting piece 51 against the non-mounting label 3 is maintained substantially equal from the start of cutting to the end of cutting. And the cutting performance can be stably maintained.
