  Moreover, in this label sticking apparatus S, as shown in FIGS. 2, 5, 6 and 7, the foremost label L transferred by the transfer positioning mechanism 20 is placed on the suction surface 11 of the suction plate 10. In addition, a guide roller 40 is provided that guides by pressing from the back side of the label L. Further, a guide roller holding mechanism 41 that holds the guide roller 40 is provided. The guide roller holding mechanism 41 enables the guide roller 40 to be retracted from the advance path of the suction plate 10 and the cutting member 31 when the suction plate 10 advances from the suction position X to the sticking position Y. More specifically, the guide roller holding mechanism 41 pivotally supports both ends of the guide roller 40 at one end portion thereof, and the other end portion rotates about the rotation shaft 42 on the machine base 1 on the upstream side of the suction plate 10. A holding frame 43 provided as possible, and a guide position R1 for rotating the holding frame to bring the guide roller 40 into contact with the suction surface 11 of the suction plate 10 (FIGS. 2, 5A, 6B, 6) (A), FIG. 7 (a)) and move to the retreat position R2 (FIG. 5 (c), FIG. 6 (b), FIG. 7 (b)) for retreating from the advance path of the suction plate 10 and the cutting member 31. The holding frame drive unit 44 is configured to be provided.

  The holding frame driving unit 44 constantly urges the holding frame 43 to the guide position R1 of the guide roller 40, and the holding frame 43 against the urging force of the urging mechanism 45 provided on the suction plate 10. The pressing member 46 is configured to be pressed and moved to the retracted position R2 in the process of moving the suction plate 10 from the suction position X to the sticking position Y.

For example, the perforation M (mark) between the frontmost label L and the label L one after the frontmost label L is detected. The control unit drives the transfer positioning mechanism 20 in response to a predetermined start signal from an operation panel (not shown) or a host, and stops the electric motor of the transfer positioning mechanism 20 based on the detection of the perforation M, thereby causing the label continuum LA Is stopped, and the label continuous body LA is positioned at a predetermined position. 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, the control unit 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 adsorbed (FIG. 9), the cutting cylinder 36 is advanced (FIG. 10). Then, when the intermediate sensor 61 detects that the affixing cylinder 13 has advanced to reach a predetermined intermediate position, the cutting cylinder 36 is retracted ( 11 and 12). When the forward end sensor 62 detects the advancement of the suction plate 10, the application of the label L to the article W by the suction plate 10 is started, and after the label L is applied, until the backward movement sensor 60 detects the suction plate 10. It reverse | retreats and the drive of the sticking cylinder 13 is stopped.
In addition, the control unit performs various operations such as control of the sticking cylinder 13 of the suction plate drive mechanism 12, suction control of the suction plate 10, and print 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, as shown in the operation explanatory diagram of FIG. 13B, first, FIG. 2, FIG. 6 (a), FIG. 7 (a), FIG. 8 and FIG. 9, the transfer positioning mechanism 20 transfers the label continuous body LA to the suction plate 10 at the suction position X, and the print head 3 The required printing is performed on the frontmost label L, the frontmost label L is opposed to the suction surface 11 of the suction plate 10, and the perforation M for cutting is a position immediately before the rear end 10a of the suction plate 10. Is positioned at a predetermined position. In this case, since the foremost label L is pressed and guided by the suction plate 10 by the guide roller 40, the foremost label L does not hang down and can be reliably attracted to the suction plate 10. The guide roller 40 is driven to rotate by the guide roller driving unit 50 in synchronism with the platen roller 4 so that the transfer speed of the label continuous body LA is the same as that of the platen roller 4. can do.

  In this state, as shown in FIGS. 1, 4B, 5B, 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. The rear end 10a of the plate 10 is projected. In this case, as shown in FIGS. 1 and 10, the foremost label L positioned at a predetermined position is adsorbed by the adsorption plate 10 and is sandwiched between the adsorption plate 10 and the guide roller 40, and the label at the rear of the label L. Since L is supported by the support member 25 and is sandwiched between the print head 3 and the platen roller 4, when the cutting member 31 comes into contact with the perforation M for cutting or in the vicinity thereof, the foremost label L is applied to the frontmost label L from the surface side. While an external force in the direction toward the back side is applied, a reaction force directed from the back side to the front side is applied to the label L that is one after the frontmost label L. A shearing force works, and a part of the side end side of the perforation M related to cutting is cut. In this case, as shown in FIG. 1, the label L that is one after the foremost label L is supported by the support member 25, and the edge 26 of the support member 25 is parallel to the perforation M for cutting. Since it is located in the vicinity of the lever perforation M, a shearing force can be applied to the perforation M related to the cutting together with the cutting member 31, and the perforation M can be reliably cut.

  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. However, as shown in FIGS. Since the abutment edge 32 is inclined, the abutment edge 32 close to the label L gradually abuts on the perforation M from the inclined end side, and a shearing force is gradually applied to the perforation M from the side edge. For example, the perforation M is cut so as to cut the object, and the perforation M can be surely cut so that the foremost label L can be separated.

  Thereafter, the suction plate 10 advances from the suction position X to the sticking position Y. In this case, as shown in FIG. 11, even if the cut at the side end side of the perforation M is a part, the frontmost label L is connected to the label L one after this, so the suction plate Since 10 is advanced by tension when it is advanced, an external force acts on the foremost label L, so that the remaining perforation M for cutting is cut by this external force. 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 to reach a predetermined intermediate position, the cutting cylinder 36 is retracted (FIG. 12). Therefore, the situation which interferes with the article | item W in the sticking position Y is prevented. At the sticking position Y, as shown in FIGS. 5C, 7B and 12, the foremost label L is sucked by the suction plate 10 and stuck to the article W.
In this case, as shown in FIGS. 6B and 7A, when the suction plate 10 advances from the suction position X to the sticking position Y, the guide roller holding mechanism 41 moves the guide roller 40 and the suction plate 10 together. Since the cutting member 31 is retracted from the advance path, an interference situation is prevented. That is, as shown in FIGS. 6 and 7, the pressing member 46 contacts and presses the outer peripheral surface of the receiving bearing 47, and the guide roller 40 rotates by pressing while rolling the outer peripheral surface of the receiving bearing 47. The holding frame 43 is rotated via the shaft 40a.

  When the forward end sensor 62 detects, the suction plate 10 is then moved backward, and the suction plate 10 is again positioned at the suction position X. In this case, as shown in FIGS. 6 and 7, the pressing member 46 is in contact with the outer peripheral surface of the receiving bearing 47, but retracts with the retracting of the suction plate 10, so the coil spring 45 d of the biasing mechanism 45. Due to this urging force, the holding frame 43 is rotated via the top 45b, and the guide roller 40 is positioned at the guide position R1. Then, the suction plate 10 is provided for the next label L again. Further, the label continuum LAL is transferred in the reverse direction and stopped at a predetermined printing position.

  Thus, according to this label L sticking apparatus, as shown in FIG. 13, the foremost label L of the label continuous body LA is adsorbed to the adsorption plate 10 without being cut first, and then cut. As in the prior art, the time for stopping the label continuum LA in the middle for cutting with the cutting mechanism 104 is not required, and accordingly, the label L application cycle can be shortened and the application efficiency can be improved. it can.

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. Efficiency can be improved. 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.
Furthermore, in the above embodiment, the pressing member 46 of the holding frame driving unit 44 contacts the outer peripheral surface of the receiving bearing 47 and the guide roller 40 can be rotated to the guide position R1 and the retracted position R2. For example, an air cylinder device in which a guide roller 40 is provided at the tip of the platen roller 4 is provided below the platen roller 4, and the sticking cylinder 13 is synchronized with an operation in which the suction plate 10 advances from the suction position to the sticking position. The guide roller 40 may be capable of moving forward and backward from the advancing path of the suction plate and the cutting member, and may be appropriately changed.

  Furthermore, in the said embodiment, although the suction plate 10 advanced from the suction position to the sticking position by the sticking cylinder 13, it was not limited to this, and the suction plate 10 advances and retreats by the sticking cylinder 13. Needless to say, the present invention can be applied to a case where the label L sucked by the suction plate 10 is sprayed and pasted by the suction plate 10.
