Description

  The present invention transports a continuous strip-less label continuous body in which a plurality of rows of labels having an adhesive layer on the back surface are provided at the boundary of a perforation, etc. The present invention relates to a label affixing device that cuts a label at a boundary and attaches it to an article.

  Generally, as a label sticking device, a label continuous body in which labels are temporarily attached to a belt-like mount is used, and a type that peels the label from the belt mount and sticks it to an article has become widespread in recent years. For the purpose of considering the environment, a non-mounting label continuous body having no belt-like mounting is also used. This continuous paperless label continuous body is called a linerless label, non-separ (registered trademark) or the like, and has a plurality of labels each having a pressure-sensitive adhesive layer on the back surface and bordered by perforations. Generally, a strip-shaped label continuous body is distributed in the form of a roll-shaped label roll wound in a roll shape.

  Conventionally, as a label sticking device for this type of backing paper-less label continuum, for example, one disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2000-281029) is known. As shown in FIG. 15, this label sticking device Sa includes a suction plate 100 that sucks the foremost label L of the label continuum LA, advances the suction plate 100, and performs predetermined conveyance by a conveyor (not shown). The label L is affixed to the article conveyed along the direction. As shown in the operation explanatory diagram of FIG. 14 (a), the label sticking device Sa removes the belt-like non-mounting label continuous body LA from the label roll (not shown) along the direction in which the labels L are arranged. First, the required printing is performed on the platen 103 by the print head 102, and then the sheet is further transferred to the frontmost label of the label continuum L by the fixed blade 105 and the rotary blade 106 of the cutting mechanism 104. L is cut from the label L one after this at the boundary (not shown). A mark is attached to the boundary, and the boundary is cut by detecting this. Then, the foremost label L is further transferred and adsorbed on the adsorption plate 100. Thereafter, the label continuum L is transferred in the reverse direction and stops at a predetermined printing position. When pasting on the article is finished, the label L is pasted again in the same process as described above.

JP 2000-2829 A

  By the way, in the conventional label sticking apparatus, as shown in FIG. 14 (a), after printing on the foremost label L, it is transported to a position where the cutting mechanism 104 is located and stopped. 106, the foremost label L is cut at the boundary from the next label L one after this, and then transferred to the suction plate 100. In order to cut the label L, the cutting mechanism is once used. Since it has to be stopped at the position 104, a time for stopping the cutting for this cutting and a time for restarting the transfer are caused, and accordingly, the label applying cycle becomes longer and the attaching efficiency is inferior. There was a problem.

  The present invention has been made in view of the above-mentioned problems, and it is possible to cut the foremost label without stopping it halfway, and to shorten the label application cycle so as to improve the label application efficiency. An object is to provide a labeling apparatus.

In order to solve the above-described problems, the label sticking device of the present invention includes a strip-like baseless label continuous body in which a plurality of labels each having a pressure-sensitive adhesive layer on the back surface are arranged in the boundary in the direction in which the labels are arranged. In the label sticking apparatus that cuts and sticks the foremost label of the label continuum from the next lower label to the boundary at the boundary,
The front surface of the label has an adsorption surface that adsorbs the surface by sucking air, the adsorption plate that affixes the back surface of the label adsorbed on the adsorption surface to the article, and the continuous label is transferred to the adsorption plate And a transfer positioning mechanism for positioning the foremost label of the label continuum at a predetermined position for attracting the suction surface of the suction plate, and the frontmost label of the label continuum positioned at a predetermined position by the transfer positioning mechanism A support member that supports the rear label from the back side thereof, and a rear boundary side of the suction plate that can be projected and retracted from a surface along the suction surface. And a cutting mechanism having a cutting member that cuts the boundary related to the cutting in contact with
The adsorbing plate constitutes a main body having an outer plate facing the label and formed with a plurality of air ports, and an adsorbing surface that adheres to the surface of the outer plate of the main body and adsorbs the surface of the label. And a rubber pad having a through hole corresponding to the air port.
The boundary of the label continuum is configured by, for example, perforations, or is specified by marks instead of perforations.

  According to this, first, the transfer positioning mechanism transfers the label continuum to the suction plate, and the frontmost label is sucked to the suction surface of the suction plate and positioned at a predetermined position. And a cutting member protrudes by a cutting mechanism, and a cutting member contacts the boundary which concerns on cutting, or its vicinity. In this case, since the foremost label positioned at a predetermined position is adsorbed by the suction plate and the rearmost label is supported by the support member, a shearing force acts on the boundary related to cutting, and the boundary related to cutting is Disconnected. In this case, the foremost label tends to be pulled along the suction surface of the suction plate due to the contact of the cutting member, but the suction surface of the suction plate is formed of a rubber pad, so the frictional resistance is large. Therefore, the label is difficult to move, and tension is generated in the label continuous body between the suction plate, the print head, and the platen. In this state, the cutting member comes into contact with the perforation of the label continuous body. It will surely be cut. For this reason, it is not necessary to provide a member such as a roller for pressing the frontmost label against the suction surface of the suction plate, and the structure can be simplified accordingly. Of course, a pressing member such as a roller may be provided.

  Then, the frontmost label is attached to the article by the suction plate. For this reason, the foremost label of the label continuum is not cut first, but is adsorbed to the suction plate and then cut, so that the label continuum is stopped halfway in order to cut by the cutting mechanism as in the prior art. Time is not required, and the labeling interval can be shortened accordingly, so that the efficiency of application can be improved.

  More specifically, the label sticking device of the present invention is configured such that Da <Db, where Da is the diameter of the air port and Db is the diameter of the through hole. Since the area of the through hole in which the suction force acts on the label is widened on the suction surface on which the label is sucked, the holding force can be increased accordingly.

  More specifically, an air flow control unit that controls the air flow of the adsorption plate is provided, and the air flow control unit is configured to transfer the label continuum toward the adsorption plate by the transfer positioning mechanism. And a suction force control means for controlling the suction force of the suction plate so that Fa <Fb, where Fa is the suction force when cutting the boundary of the label relating to the cutting, and Fb. It is said. Accordingly, if the suction force Fa when the continuous label body is transferred toward the suction plate by the transfer positioning mechanism is set to be relatively weak, the continuous label body can be moved smoothly. On the other hand, if the suction force Fb at the time of cutting the boundary of the label related to the cutting is made relatively strong, the holding force becomes high, so that the label can be reliably cut without being moved.

  More specifically, a transfer positioning control unit that controls the transfer positioning mechanism is provided, and the transfer positioning control unit transfers the label continuous body to the suction plate when the label continuous body is transferred to the suction plate. It is configured to include pull-back positioning means for feeding in excess of the position and then pulling back to position the frontmost label of the label continuum. If the label slacks during feeding, cutting may be uncertain, but since the label is pulled back, tension is generated in the label continuum between the suction plate, the print head, and the platen. In this state, the cutting member comes into contact with the perforation of the label continuum, so that the cutting can be reliably performed.

Furthermore, more specifically, the suction plate has two positions: a suction position for sucking the front surface of the label continuum on the suction surface and a sticking position for sticking the back surface of the sucked label to the article. It is set as the structure which can be moved forward and backward.
Accordingly, the transfer positioning mechanism transfers the label continuum to the suction plate at the suction position, and the frontmost label is sucked on the suction surface of the suction plate and positioned at a predetermined position. Then, a part or all of the boundary related to the cutting is cut by the cutting mechanism. Thereafter, the suction plate advances from the suction position to the sticking position. In this case, when the entire boundary is cut by the cutting member, the frontmost label is directly sucked by the suction plate and attached to the article. For example, when the cutting member cuts a part on the side edge side of the boundary, the frontmost label is connected to the label one rearward from this, so that the suction plate is pulled by tension. Therefore, an external force acts on the foremost label, so that the remaining boundary related to the cutting is cut by this external force. As a result, the foremost label is attracted to the suction plate and attached to the article. Thus, when the cutting member cuts part of the side edge side of the boundary, the remaining boundary is cut when the suction plate advances, so that the time required for cutting can be shortened accordingly. However, the sticking efficiency can be improved.

  According to the present invention, the foremost label of the label continuum is adsorbed to the suction plate without being cut first, and then cut, so that the label continuum can be cut by a cutting mechanism as in the prior art. It is not necessary to have a time to stop halfway, and the label application cycle can be shortened accordingly, so that the application efficiency can be improved. Also, when cutting the label, the foremost label tends to be pulled along the suction surface of the suction plate by the contact of the cutting member, but the suction surface of the suction plate is formed by a rubber pad. In this state, the label is difficult to move, and tension is generated in the label continuous body between the suction plate, the print head, and the platen. In this state, the cutting member is a sewing machine of the label continuous body. Since it abuts on the eyes, it is surely cut. For this reason, it is not necessary to provide a member such as a roller for pressing the frontmost label against the suction surface of the suction plate, and the structure can be simplified accordingly.

Is provided.

  Moreover, as shown in FIG. 6, this label sticking apparatus S is provided with the control part 40 which is implement | achieved by functions, such as CPU, and controls each part. As shown in FIG. 2, the controller 40 includes an air flow controller 41 that controls the adsorption of the adsorption plate 10, that is, controls the air flow of the adsorption plate 10. The air flow control unit 41 uses the transfer positioning mechanism 20 to transfer the label continuum LA toward the suction plate 10 as Fa, and the suction force when cutting the boundary M of the label L to be cut into Fb. In this case, the suction force control means 42 for controlling the suction force of the suction plate 10 is provided so that Fa <Fb. For example, two systems of air suction paths, that is, a path for the suction force Fa and a path for the suction force Fb are provided, and the suction force control means 42 switches between these paths using a solenoid or the like. The air flow control unit 41 stops suction of air at the sticking position Y of the suction plate 10, blows out air from the air port 15 and the through hole 17, and presses and sticks the label L toward the article W. A blowing means 43 is provided.

  Further, as shown in FIG. 6, the control unit 40 includes a transfer positioning control unit 44 that controls the transfer positioning mechanism 20. A sensor (not shown) for detecting the mark of the frontmost label L or the label L one after the frontmost label L is provided in the transfer path of the label continuum LA. For example, the perforation M (mark) between the frontmost label L and the label L one after the frontmost label L is detected. The transfer positioning control unit 44 receives an activation from the operation panel (not shown) or the upper unit to the control unit 40, and the control unit 40 drives the transfer positioning mechanism 20 by a start signal. First, the label continuum LA is attached to the platen 4. Pull back to the position to perform printing, then send out the label continuum LA, stop the electric motor of the transfer positioning mechanism 20 based on the detection of the perforation M, stop the transfer of the label continuum LA, Position body LA in place. That is, by this stop control, in the transfer positioning mechanism 20, the perforation M between the foremost label L and the label L one after the foremost label L is positioned at the predetermined position. The label continuum LA is transferred and positioned.

  Further, as shown in FIGS. 9, 13, and 14B, the transfer positioning control unit 44 moves the label continuous body LA from the predetermined position when transferring the label continuous body LA toward the suction plate 10. Feeding means (symbol α in FIG. 14 (b)) is then provided, followed by pulling back positioning means 45 for pulling back and positioning the foremost label L of the label continuum LA.

  Further, the control unit 40 includes a cutting control unit 46 that controls the cutting member driving mechanism 35. As shown in FIGS. 8 to 12, the sticking cylinder 13 that drives the suction plate 10 is provided with a sensor that detects the position of the suction plate 10. As sensors, a backward end sensor 60 that detects that the suction plate 10 is at the suction position X, an intermediate sensor 61 that detects a predetermined intermediate position, and a forward end sensor 62 that detects that the suction plate 10 is at the pasting position Y are provided. Yes. And based on the detection of this sensor, the cutting cylinder 36 of the cutting member drive mechanism 35 is driven. Specifically, when the retracting end sensor 60 detects the suction position X, the cutting cylinder 36 is held at the retracted position (FIGS. 8 and 9), and the suction plate 10 holds the frontmost label L. When sucked (FIG. 9), the cutting cylinder 36 is advanced (FIG. 10), and then immediately retracted. Then, when the affixing cylinder 13 moves forward and the advancing end sensor 62 detects the advancing of the suction plate 10, the label L is pasted on the article W by the suction plate 10, and after the label L is pasted, the suction plate 10 is moved backward. Retraction is performed until the end sensor 60 detects the driving of the pasting cylinder 13.

Further, as shown in FIGS. 7C and 14B, the transfer positioning control unit 44 pulls back the label continuous body LA at a predetermined time after the cutting of the frontmost label L of the label continuous body LA. The separating means 47 for separating the leading end of the label L, which has become the foremost position of the label continuum LA by cutting, from the moving member is provided. In the embodiment, the transfer positioning control unit 44 pulls back the label continuous body LA at least before the suction plate 10 moves from the sticking position X to the suction position Y after cutting the frontmost label L of the label continuous body LA. Then, the suction plate 10 is separated from the moving path of the members attached thereto. When the intermediate sensor 61 detects that the affixing cylinder 13 has advanced and has reached a predetermined intermediate position, the pulling means 47 pulls back the label continuous body LA by a predetermined length (reference symbol e in FIG. 14B). In the label continuum LA that is pulled back by the pulling means 47 of the transfer positioning control unit 44, the stop position of the leading end of the label L that is the foremost position of the label continuum LA is as shown in FIG. It is set downstream of the roller 4.
In addition, the control unit 40 performs various operations such as control of the affixing cylinder 13 of the suction plate driving mechanism 12 and printing control by the print head 3.

  Therefore, when the label L is stuck on the article W by the label sticking apparatus S according to the embodiment, first, the timing chart of FIG. 13 and the process diagram of FIG. As shown in FIGS. 8 and 9, the transfer positioning mechanism 20 transfers the label continuum LA and first causes the print head 3 to perform the required printing on the foremost label L, and the foremost label L Is opposed to the suction surface 11 of the suction plate 10 and the perforation M for cutting is positioned at a predetermined position located immediately before the rear end 10 a of the suction plate 10.

  In this case, first, the label continuous body LA is pulled back, and the frontmost label is back-fed to the position of the platen roller 4 (printing position) (T0 (* 7) in FIG. 13). Then, the label is printed and sent to a predetermined position, and the label continuous body is further fed from the predetermined position, that is, the frontmost label is transported by an extra distance (α) to the suction plate 10 (see FIG. 13, T1 and T2 (* 1)), and then pulls back to position the foremost label L of the label continuous body LA, that is, reversely transports by a predetermined distance (β) and stops (T3 in FIG. 13). Thereby, the slack of the label L can be removed and the label L can be put in a stretched state. It is desirable that the predetermined distance (α) and the predetermined distance (β) can be set to each by a command from a host (not shown) or an input from the operation unit.

  In this case, when the foremost label L is transported by an extra distance (α) from the suction plate 10 (T1, T2 in FIG. 13), the suction force Fa of the suction plate 10 is set to be relatively weak. ("Suction 1 [weak]" in FIG. 13), the label continuum LA is thus moved smoothly. On the other hand, when the reverse conveyance is performed for a predetermined distance (β), the suction force Fb of the suction plate 10 is set to be relatively strong (T3 (* 2) “Suction 2 [Strong]” in FIG. 13). Also by this, the slack of the label L can be removed and the label L can be put in a stretched state.

  In this state, as shown in FIGS. 1, 5B, 7B, and 10, the cutting cylinder 36 of the cutting member drive mechanism 35 is operated to suck the cutting member 31 of the cutting mechanism 30. It protrudes at the rear end 10a of the plate 10 (T4 (* 3) in FIG. 13). In this case, since the foremost label L positioned at a predetermined position is adsorbed by the adsorption plate 10 and the rearward label L is supported by the support member 25, a shearing force acts on the boundary M related to cutting, A part of the boundary M related to the cutting is cut. Further, in this case, the foremost label L tends to be pulled along the suction surface 11 of the suction plate 10 by the contact of the cutting member 31, but the suction surface 11 of the suction plate 10 is formed by the rubber pad 18. Therefore, the frictional resistance is increased, and therefore the label L is hard to move and is surely cut. For this reason, it is not necessary to provide a member such as a roller for pressing the frontmost label L against the suction surface 11 of the suction plate 10, and the structure can be simplified accordingly. Of course, a pressing member such as a roller may be provided.

  Further, in the suction plate 10, as shown in FIG. 2, the relationship between the diameter Da of the air port 15 and the diameter Db of the through hole 17 is set to Da <Db. 11, the area of the through-hole 17 where the suction force acts on the label L is widened, so that the holding force can be increased accordingly, and also in this respect, the cutting can be reliably performed. Further, since the suction force Fb when cutting the boundary M of the label L related to the cutting is relatively strong, the holding force is increased accordingly. Can be cut. Further, since the label continuous body LA is transported by a predetermined distance (α) more than the predetermined position and then reversely transported by the predetermined distance (β), the label L can be loosened. Since the L can be in a stretched state, even if the cutting member 31 slightly deviates from the perforation, it can be surely cut from the perforation by the action of tension.

  Furthermore, in this case, when the cutting cylinder 36 of the cutting member drive mechanism 35 is actuated, the cutting member 31 rotates and protrudes, as shown in FIGS. 1, 5B, 7B and 10. As described above, since the contact edge 32 of the cutting member 31 is inclined, the contact edge 32 gradually contacts the perforation M from the inclined end side of the contact edge 32 close to the label L, and the shearing force is gradually applied to the perforation M from the side edge. Therefore, the so-called perforation M is cut so as to cut the object with a heel, so that the perforation M can be surely cut and the foremost label L can be separated. Thereafter, the cutting cylinder 36 moves backward (T4 (* 3) in FIG. 13).

  Next, the suction plate 10 advances from the suction position X to the sticking position Y and performs a sticking operation (T5 to T7 in FIG. 13). In this case, as shown in FIG. 7C and FIG. 11, even if the cut at the side end side of the perforation M is a part, the foremost label L is connected to the label L one after this. Since the suction plate 10 is pulled by tension when the suction plate 10 advances, an external force acts on the foremost label L, and the external perforation M related to the cutting is cut by this external force. It will be done. Further, since a part of the side end side of the perforation M is cut, the cutting is triggered as compared with the case where the perforation M is not cut, and the cutting is very easily performed.

  Then, when the intermediate sensor 61 detects that the pasting cylinder 13 has advanced and has reached a predetermined intermediate position, the label is back-feeded by a predetermined amount as shown in FIGS. 7C and 12 (T6 in FIG. 13). (* 4)). That is, after the foremost label L is cut by the separating means 47 and before the suction plate 10 moves from the sticking position X to the suction position Y, the label continuous body LA has a predetermined length (FIG. 14 ( b) Middle code e) Pulled back and pulled away from the movement path of the suction plate 10 and the members attached thereto. In this case, since the stop position of the leading edge of the label L that has newly become the foremost position of the label continuum LA is set downstream of the platen roller 4, the leading edge of the label L that has become the foremost position is the platen roller. Therefore, it is possible to prevent the label L from being caught in the platen roller 4 during printing. That is, when the leading edge of the label L, which is newly in the foremost position, is returned to the position of the platen roller 4, the time for the leading edge of the label L to remain on the platen roller 4 becomes long, and the glue at the leading edge of the label L becomes longer. However, the leading edge of the label L may be wound around the platen roller 4 during printing. However, it is possible to prevent the platen roller 4 from being caught during printing. In this case, the label L is pulled back during printing. In this case, since the label L immediately enters the printing operation without stopping, the situation of being caught in the platen roller 4 is suppressed.

  Further, when the adhering cylinder 13 advances (T7 in FIG. 13) and the adsorbing plate 10 reaches the adhering position Y as shown in FIG. 7C, the adsorbing plate is detected based on the detection of the forward end sensor 62. Air is blown from 10 (T8 (* 5) “Blowout” in FIG. 13), and the frontmost label L is separated from the suction plate 10 and attached to the article W. Thereafter, the suction plate 10 is retracted, and the suction plate 10 is again positioned at the suction position X (T9 (* 6) in FIG. 13). In this case, as shown in FIG. 12, since the leading end of the label L which has newly become the forefront of the label continuum LA is separated from the moving path of the suction plate 10 and the members attached thereto, this label L It is possible to prevent the leading end of the label from abutting and interfering with the suction plate 10 or the cutting member 31, and to avoid rubbing and scratching the leading end of the label L. For this reason, the situation which interferes with the next label sticking can be prevented.

  Thus, according to this label sticking apparatus, the foremost label L of the label continuum LA is adsorbed to the suction plate 10 without being cut first, and then cut, so that, as in the prior art, the cutting mechanism The time for stopping the label continuum LA in the middle for cutting at 104 becomes unnecessary, and accordingly, the label L application cycle can be shortened, and the application efficiency can be improved.

In the above embodiment, in the cutting mechanism 30, the cutting member 31 cuts a part of the side end side of the perforation M related to cutting. However, the present invention is not necessarily limited to this, and the cutting member The entire perforation M may be cut by the protrusion 31. However, since the stroke of the cutting cylinder 36 is correspondingly increased, it is preferable to cut part of the side end side of the perforation M and then cut by the advancement of the suction plate 10 as in the embodiment. , Can improve the efficiency. That is, when the cutting member 31 cuts a part of the side end side of the perforation M, the remaining perforation M is cut when the suction plate 10 advances, so that the time required for cutting can be shortened accordingly. In this respect, the sticking efficiency can be improved.
In addition, when the boundary of the label continuous body LA is not the perforation M but the mark on the back surface of the label continuous body LA, for example, the cutting provided on the suction plate 10 in a state where the conveyance of the label continuous body LA is stopped If the member 31 protrudes and the entire boundary is cut, the cutting accuracy of the cutting mechanism 30 is improved. Even if the perforated line M is provided in the label continuous body LA, it is useful when the accuracy of cutting is required.

In the above embodiment, the support member 25 is formed of a plate-like member. However, the support member 25 is not necessarily limited to this, and the support member may be formed of the platen roller 4. If the support member is composed of the platen roller 4, the support member can be shared, and the number of parts can be reduced accordingly.
Further, the shape of the cutting member 31 and the shape of the support member 25 are not limited to the shapes described above, and may be appropriately changed, for example, formed in a blade shape.
Further, in the above embodiment, the retreat timing of the cutting member 31 is performed before moving to the attaching position X of the suction plate 10 (FIG. 13 T6 (* 4)), but is not necessarily limited to this. If it is before the suction plate 10 reaches the sticking position X, it may be performed at any timing after the suction plate 10 is moved.

  Furthermore, in the above-described embodiment, the present invention is applied to a type in which the suction plate 10 advances from the suction position X to the sticking position Y by the sticking cylinder 13 and the label L is stuck by blowing air. The present invention is not limited to this. For example, the suction plate 10 may be advanced from the suction position X to the sticking position Y by the sticking cylinder 13 and the label L may be stuck by pressing the suction plate 10. . Moreover, it cannot be overemphasized that it can apply to the thing which sprays and sticks the label L attracted | sucked with the suction plate 10 by the suction plate 10, without the suction plate 10 advancing and retracting by the sticking cylinder 13.
