The buffer roll 72 is always kept at the position shown in FIG. 1 via an urging means (not shown), and moves to the right side in the figure when the label original fabric M is fed back to loosen the film F. Is to prevent.

  Next, the label manufacturing process in the present embodiment will be described with reference to FIGS. Here, it is assumed that a conveyance path (not shown) is provided in the label forming apparatus 10 and adherends to which labels L are attached one by one are sequentially conveyed on the conveyance path. Further, each label L discharged from the label forming apparatus 10 is peeled off the release sheet S by an operator and manually attached to the adherend one by one, and different print information for each adherend is printed from a host computer (not shown). It is assumed that information is input and temporarily stored by a control device (not shown) of the label forming apparatus 10.

  In the case of performing initial setting work, when a switch of a control device (not shown) is turned on and the power is turned on, the flat portion 52A of the roll 50 is positioned on the impression cylinder 51 side as shown in FIG. A large clearance is formed between the pressure drum 51 and the print head 30 is maintained at a position separated from the platen roll 31 by a moving mechanism (not shown). The label original fabric M held on the holding roll 24 is pulled out and passed through the printing unit 14 and the pasting unit 18, and the protective film F is peeled off from the peeling film PF and passed through the pasting unit 18. Then, it is stuck to the label base material LB and laminated, and the lead end is fixed to the take-up roll 60. The lead end of the peeling film F is fixed to the film take-up roll 45.

  When automatic operation of an operation display (not shown) is selected, the print head 30 descends toward the platen roll 31 and waits (see FIG. 4). When a sensor (not shown) detects that the adherend has been conveyed, print information is input from the host computer to the label forming apparatus 10, temporarily stored by a control apparatus (not shown), and a label issuing command is issued. The first and second drive units 61 and 62 are driven in the direction of feeding out the label original fabric M to start the feeding out of the label original fabric M and the protective film F. At the same time, the print information temporarily stored by the control device is predetermined. Is printed by the printing unit 14 according to the program. The roll 50 and the film holding roll 40 also rotate via a brake motor (not shown). The label base material LB on which the printing has been performed is fed out together with the release sheet S to the pasting unit 18, and the protective film F is pasted on the printing surface by the roll 50 and the impression cylinder 51. At the same time, the cutout C is formed so that the label outer shape forming blade 55A and the half-cut blade 55B surround the printing surface (see FIGS. 5 and 6).

  The label L on which the printing has been performed and the protective film F is pasted and the cuts C are formed is extracted forward when passing through the plate material 20 (see FIG. 7), and the outside of the label forming apparatus 10 It is discharged and received by the worker. The roll 50 stops rotating when the flat surface portion 52A is positioned on the impression cylinder 51 side (the state shown in FIG. 7), and the film holding roll 40 stops rotating when the feeding of the label original fabric M is finished. Then, it becomes locked. Then, the operator can easily and quickly peel the protruding piece S1 of the release sheet S from the received label L and attach it to the adherend.

  When the label L is discharged, the label original fabric M and the protective film F are fed out to the tip of the plate material 20, and the label base material LB in the region is not printed. When the printing is started, the label original fabric M is wasted. Therefore, the motors M1 and M2 in the first drive unit 61 and the second drive unit 62 constituting the feed back feeding device 23 are reversely rotated to feed back the original label M (see FIG. 8). When reverse feeding is performed, the print head 30 moves to a position separated from the platen roll 31. Further, the length in which the reverse feeding is performed substantially corresponds to the length of the label original fabric M existing between the front end portion of the plate material 20 and the print head 30. At this time, since the film holding roll 40 is locked by a brake motor (not shown), the buffer roll 72 moves to the right side of the slot 71 and acts so that the protective film F is not loosened. In addition, since the roll 50 is locked in a state where the flat surface portion 52 </ b> A is positioned on the pressure drum 51 side, the protective film F does not get entangled with the outer periphery of the roll 50.

  After the reverse of the original label M is thus performed, the print head 30 is moved to the platen roll 31 side as shown in FIG. Thereafter, the label L is formed in the same manner.

Therefore, according to such an embodiment, since the cut surface C corresponding to the shape of the label L can be formed at the same time that the printing surface is protected by the protective film F, the protective film F can be applied. There is no need to separately provide a roll and a roll for forming the notch C, the space for component placement along the feed direction of the label original fabric M can be set short, and the pitch between the labels is set short and the label base Wasteful consumption of the material LB can be avoided and the label forming apparatus 10 can be downsized.
Moreover, since the roll 50 has a substantially D-shaped cross-sectional shape and is provided with a flat surface portion 52A, when the flat surface portion 52A is located on the impression cylinder 51 side, the reverse of the label original fabric M and the protective film F is obtained. The feeding operation can be performed smoothly. Therefore, for example, when a print detection sensor is arranged immediately after the printing unit 14 to detect a print failure, even if it is detected as a failure when printing individual information that can be individually identified, etc. By recalling the printing information temporarily stored by the control device and printing the printing information immediately and repeatedly, it is possible to apply the label while clearly taking the correspondence with the adherend.
