Via the die receiving plate.
[0003]
[Problems to be solved by the invention]
However, in the conventional apparatus, since the foil pressing die and the cutter die are advanced and retracted through a common driving device, the foil pressing operation speed and the cutting formation speed are in a state of matching.
However, since the foil stamping is performed by transferring it to the surface of the label base material, if the operation speed of the foil stamping die is set to ensure this transfer, the accuracy of the cutting by the cutter die is relatively inferior. Inconvenience.
On the other hand, when the operation speed of the cutter die is set so as to be appropriate for the formation of the notches, there is a disadvantage that the accuracy of foil pressing is relatively lowered.
In other words, the foil stamping die can transfer the foil more reliably if it takes time to contact the label substrate for as long as possible in one cycle, while the cutter die can quickly cut the label substrate and return. You can make a clean cut.
[0004]
OBJECT OF THE INVENTION

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a label manufacturing apparatus and method according to the present invention will be described with reference to the drawings.
[0010]
FIG. 1 is a schematic front view of a label manufacturing apparatus according to this embodiment. In this figure, a label manufacturing apparatus 10 includes a printing apparatus 11, a foil pressing apparatus 12 arranged on the downstream side (right side in FIG. 1) of the printing apparatus 11, and a die cutting apparatus arranged on the downstream side of the foil pressing apparatus 12. 13 and a feeding device 14.
[0011]
As shown in FIG. 2A, the label manufacturing apparatus 10 sends the label base material L to the buffer region 17 by the feeding device 14 after printing P on the surface of the strip-shaped label base material L. It has become. Here, the label base material L on which the printing P is applied is configured to have a layer structure in which the label sheet S1 is attached to the surface of the release material S via the adhesive A.
[0012]
The foil stamping device 12 is provided with a first driving device 20 disposed at the lower portion of the frame F, and is movable by a predetermined stroke in the vertical direction by the first driving device 20, and a predetermined heating means is provided therein. The equipped foil pressing die 21, the foil pressing die receiving plate 22 positioned on the back side of the label base material L at the lower part of the foil pressing die 21, and the roll holding roll of the foil 24 disposed on the upper part of the foil pressing die 21 23 and a foil take-up roll 25 that winds an area that is not pressed after passing through the area of the foil pressing die 21. In the present embodiment, a gold foil is used as the foil 24, and this gold foil is transferred to the surface of the label base material L on which the printing P has been applied by heat. At this time, the pressing surface of the foil pressing die 21 is provided with a convex shape portion (not shown) corresponding to the region where the printing P is applied, and the foil 24 is placed on the surface of the label substrate L by the convex shape portion. Transferred (see FIG. 2B). The foil 24 is pulled out from the holding roll 23, and is overlapped on the printing P surface side between a pair of nip rolls 26, 26 that sandwich the label base material L from above and below, and is sent out together with the label base material L. The part is wound up by the foil winding roll 25 through a pair of nip rolls 27, 27 located on the downstream side of the foil pushing device 12.
[0013]
The first drive device 20 includes a servo motor 30 having a gear head 34 as a reduction device, a gear box 32 connected to an output shaft 35 of the servo motor 30 via a timing belt 31, and the gear box 32. And an elevating shaft 33 to which the foil stamping die 21 is fixed at the upper end. A total of four elevating shafts 33 located near the respective corners of the foil stamping die 21 are used. The gear box 32 includes an eccentric shaft and a gear train (not shown), and converts the rotational motion of the servo motor 30 into the vertical linear motion of the lifting shaft 33 via a known crank shaft and crown rod. It has become. The lifting / lowering speed of the lifting / lowering shaft 33 is set to a speed of reciprocating 150 times per minute. Specifically, the rotation speed of the output shaft 35 of the servo motor 30 provided with the gear head 34 is set to 150 rpm. Thereby, when one reciprocation of the foil stamping die 21 is one shot, the foil stamping die 21 operates at a speed of 150 shots per minute. In the present embodiment, the operation speed of the foil stamping die 21 is preferably 150 shots, but according to the present invention, it can be changed within about 100 to 200 shots. This is because if the foil stamping die 21 exceeds 200 shots, the transfer time becomes too short and insufficient for transfer, whereas if it is less than 100 shots, the label substrate L is burnt.
[0014]
The die-cutting device 13 is provided with a second driving device 40 disposed at the lower part of the frame F, and is movable by a predetermined stroke in the vertical direction by the second driving device 40, and a protective film to be described later is attached. A cutter die 44 provided with a blade 43 for forming a cut C (see FIG. 2C) in the label base L on the lower surface side, and at the lower side of the cutter die 44, located on the back side of the label base L And a cutter die receiving plate 45 to be configured. The second driving device 40 has a structure substantially similar to that of the driving device 20 on the foil stamping device 12 side. Therefore, the description is omitted here assuming that the same reference numerals are used. In this embodiment, the rotation speed of the output shaft 35 of the servo motor 30 provided with the gear head 34 is set so that the cutter die 44 operates at a speed of 300 shots per minute when one reciprocation is taken as one shot. Is set to 300 rpm. However, the cutter die 44 can be set to operate at a speed of 100 to 350 shots. If it is less than 100 shots, it will be difficult to make a clean cut, whereas if it is faster than 350 shots, an incomplete cut will be likely to occur.
[0015]
In the present invention, as shown in FIG. 2C, a protective film FL is attached to the label base material L after the foil 24 is transferred by the foil pressing device 12. This protective film FL is supported by a feed roll 50 disposed above the die-cutting device 13 in the original fabric state, and is fed from the feed roll 50 to peel off the release material S2, and then between the pair of nip rolls 52, 52. It is attached to the printed P surface side of the label base material L through. The release material S2 is taken up by the take-up roll 55.
[0016]
The label base material L that has passed through the die cutting device 13 is sequentially sent out by the feeding device 14. The feeding device 14 includes a motor M that is intermittently driven, an output shaft 57 of the motor M, and a nip roll 60 that is biased toward the outer peripheral surface of the output shaft 57. Therefore, when the motor M is driven, a winding force is applied to the label base material L. In addition, the rotation speed of the output shaft 57 in the motor M is set to 100 rpm in this embodiment.
[0017]
Next, the label manufacturing method in this embodiment will be described.
[0018]
The label base material L on which printing P has been performed by the printing device 11 is sandwiched between the feeding device 14 and the nip roll 60 and is intermittently wound at a set speed by driving the motor M of the feeding device 14. It becomes. That is, when viewed from the printing apparatus 11 side, the label base material L is sent out to the foil pressing apparatus 12 side. The feeding device 14 stops driving at the timing when the foil pressing device 12 and the die cutting device 13 are operated, and keeps the position of the label base material L constant.
[0019]
In the foil stamping device 12, the foil stamping die 21 descends with the foil 24 superimposed on the surface of the label substrate L, and the foil 24 is transferred to the print P surface of the label substrate L by the heat of the die itself. At this time, since the operation speed of the foil stamping die 21 is slower than the operation speed of the cutter die 44 described above, the preset region is transferred from the foil film in a relatively long pressing time. And the foil part which is not transcribe | transferred will be wound up by the foil winding roll 25 one by one in the state linked to the strip | belt shape.
[0020]
The label base material L on which the transfer of the foil 24 has been completed is formed with a cut C after the protective film FL is pasted in the area of the die-cutting device 13 which is the next process. Since this cutting is performed at a relatively high speed, a beautiful cut line is surely formed.
[0021]
The label base material l thus subjected to foil pressing and die cutting is wound up by a predetermined amount while the foil pressing device 12 and the die cutting device 13 are stopped, and thereafter the label is postprocessed by repeating the same cycle. Can be sent to. Examples of the post-process include a winding device that winds the label base material L, a sheet cutting device that cuts the label base material L into a sheet shape, and the like.
[0022]

[0023]
For example, in the above-described embodiment, the first and second driving devices 20 and 40 are provided, respectively. However, two power transmission systems are provided for a single servo motor, and the foil pressing is performed by making their rotation amounts different. The operation speeds of the device 12 and the die cutting device 13 can be controlled independently. In short, various design changes can be made in the present invention as long as the operation speed can be adjusted in accordance with the material of the label, the thickness of each layer, the foil pressing conditions, and the notch forming conditions. Further, the structure of the label base material L in the embodiment is not limited to the illustrated configuration example.
