Description

The present invention relates to a roll-shaped engraving for transferring a transfer foil to, for example, a side surface of a cylindrical body or an elliptical tubular body, a foil transfer device using the same, and a foil transfer method.

There is a method of decorating by transferring a transfer foil or a transfer pattern to an object to be transferred.
Patent Document 1 describes a plate-shaped transfer plate on which characters, symbols, figures, etc. (hereinafter referred to as characters) are engraved, and a transferred object having a cylindrical shape via a transfer sheet on which a transfer foil is vapor-deposited. This is a rolling foil transfer method in which transfer is performed on the side surface of the transfer target by pressing it against the outer peripheral surface while heating and further rolling the transfer target along the transfer plate. The same transfer can be performed by horizontally moving the flat plate-shaped transfer plate instead of rolling the transferred object.

Further, in Patent Document 2, a long strip-shaped transfer sheet for thermal transfer, which has already been vapor-deposited with a transfer pattern composed of characters or the like, is conveyed from one end to a thermal transfer section, and the transfer pattern is set on the thermal transfer section. The transfer is performed by applying heat and pressure to the transfer surface with a silicon roller for thermal transfer.

As shown in FIG. 1, in the foil transfer device, the unwinding reel 1 is arranged on the upstream side at the left end in the drawing, and the take-up reel 2 is arranged on the downstream side at the right end in the drawing. The take-up reel 2 is pivotally supported on the rotating shaft of the take-up motor 22, and the take-up reel 1 is pivotally supported on the rotating shaft of the back tension motor 21 via a clutch mechanism (not shown). A transfer sheet 4 described later is stretched between the take-up reel 2 and the take-up reel 2. Then, by intermittently driving the take-up motor 22 in the forward rotation direction, the transfer sheet 4 can be traveled from the upstream side to the downstream side, which is the traveling direction. Further, by driving the back tension motor 21 in the reverse rotation, a predetermined tension (back tension) acting in the direction opposite to the traveling direction (upstream direction) is applied to the transfer sheet 4 via the clutch mechanism, and the transfer sheet 4 is generated. It is possible to remove slack that is easy to do.

A plurality of guide members 3 including guide rollers 3A and guide columns 3B are arranged between the unwinding reel 1 and the take-up reel 2, and the transfer sheet 4 is assisted by these guide members 3 on the upstream side. It is arranged so that it can run from the downstream side (running direction).

The transfer sheet 4 is a long strip-shaped (also referred to as a tape-shaped) sheet in which a transfer foil composed of a metal foil or the like is laminated on a base film made of a synthetic resin by vapor deposition or the like, and is wound multiple times. It is composed of.

A cylindrical roll-shaped marking 5 is provided between the left and right guide columns 3B (guide members 3) provided in the central portion of the foil transfer device, and far infrared rays are provided around the roll-shaped marking 5. The type heaters 6 are arranged to face each other.

As shown in FIG. 4, the roll-shaped marking 5 is a cylindrical member made of a rubber having a relatively high hardness, and the outer peripheral surface of the roll-shaped marking 5 is used to transfer the transferred material. An engraved portion 5a composed of characters and the like (in FIG. 4, a pattern in which star-shaped figures are arranged vertically and horizontally) is formed.
The roll-shaped marking 5 is fixed to the rotary shaft of a servomotor (not shown) in a state of being externally inserted around a columnar mounting jig 7 rotatably supported by a one-way clutch mechanism (also not shown). When it receives the power of the servo motor, it can rotate at a constant speed. By rotating the roll-shaped marking 5 at a constant speed, it is possible to suppress temperature unevenness that tends to occur in the engraved portion 5a of the roll-shaped marking 5 heated by the heater 6, and eventually to suppress the occurrence of transfer unevenness. ing. The servo motor is connected to a controller (not shown), and the controller controls the start time and stop time of the rotation of the roll-shaped marking 5 in response to input from a program or touch panel, and adjusts the rotation angle of the roll-shaped marking 5. Etc. can be controlled.

A rotary moving jig 8 is provided at a position facing the roll-shaped marking 5 via the transfer sheet 4. The rotary moving jig 8 is equipped with a motor (not shown) that holds the object 9 to be transferred at the tip of the rotary shaft and drives it to rotate around the shaft, and is approaching and separating from the roll-shaped marking 5. It is provided so as to be movable in a direction (also called a front-rear direction).

Then, by moving the rotary movement jig 8 forward under the control of a controller (not shown), it is possible to press-contact the side surface of the object to be transferred 9 with the roll-shaped marking 5 via the transfer sheet 4. At the same time, by driving the motor, it is possible to rotate the object to be transferred 9. Therefore, by rotating the transfer object 9 and reciprocating the rotary movement jig 8 in the front-rear direction according to the shape of the transfer object 9, the entire circumference is imitated by the side surface of the transfer object 9 having an elliptical shape. It is possible to press-contact the roll-shaped marking 5 over the entire range, and it is possible to keep the contact pressure at the time of press contact constant.

As shown in FIGS. 1 to 3, an extruder 10 made of an air cylinder, a hydraulic cylinder, or the like may be arranged between the rotary moving jig 8 and the guide column 3B on the left side of the drawing. The extruder (actuator) 10 has a support arm 11 that moves back and forth horizontally, and a round bar-shaped tension guide 12 extending in the vertical direction is provided at the tip of the support arm 11. As shown in FIGS. 2 and 3, when the support arm 11 is projected and the transfer sheet 4 is pressed on the outer peripheral surface of the tension guide 12, a strong tension acts on the transfer sheet 4 to suppress the occurrence of wrinkles. Is possible. The outer peripheral surface of the tension guide 12 is preferably polished or chemically surface-treated so that the transfer sheet 4 can slide smoothly.

Next, a foil transfer method using the foil transfer device will be described.
(1) First step (initial state)
As shown in FIG. 1, the roll-shaped marking 5 is rotated at a constant speed, and temperature unevenness that tends to occur on the outer peripheral surface of the roll-shaped marking 5 is suppressed.
The take-up motor 22 is in a non-driving state (stopped state), and the back tension motor 21 is driven to remove slack that tends to occur in the transfer sheet 4. Further, the rotary moving jig 8 is in a state of being moved to a rearward retracted position away from the roll-shaped marking 5.
In this first step (initial state), the elliptical tubular object 9 to be transferred is attached to the tip of the rotating shaft of the motor mounted on the rotary moving jig 8.

(2) Second step (start of transcription)
The second step (transfer start) is performed by setting a start switch (not shown) to ON.
At the same time as the switch is turned on, the driving of the servomotor is stopped, the rotation of the roll-shaped marking 5 is stopped, and the engraving portion 5a is controlled to come to a predetermined stop position. As a result, the transfer material 9 and the roll-shaped marking 5 are relatively positioned, and the engraving portion 5a of the transfer material 9 can be set to a predetermined start position (or initial rotation angle). Become. In addition to the method of controlling the servomotor itself, the rotation of the roll-shaped marking 5 is stopped by detecting a positioning portion (for example, a bolt 7a shown in FIG. 4) provided on the roll-shaped marking 5 with an external sensor. It may be a method of stopping.
As described above, since the roll-shaped marking 5 is rotatably supported on the rotating shaft of the servomotor via the one-way clutch mechanism, the roll-shaped marking 5 is stopped from rotating and then rolled. It is assumed that the roll-shaped marking 5 may move slightly before the object to be transferred 9 comes into contact with the marking 5, causing misalignment. In that case, a tension belt for correction is hung on the rotating shaft to cause misalignment. It is good to prevent. Alternatively, the misalignment may be prevented by forcibly clamping the rotating shaft, the pulley or the like (not shown) via an air cylinder or the like (not shown) while measuring the timing.

(3) Third Step Next, as shown in FIG. 2, the rotary moving jig 8 is moved from the rear retracted position to the front pressure contact position approaching the roll-shaped marking 5, and is rolled on the side surface of the transferred object 9. The outer peripheral surface (engraving portion 5a) of the shape marking 5 is pressed against each other, and the transfer sheet 4 is sandwiched between the side surface of the object to be transferred 9 and the outer peripheral surface of the roll-shaped marking 5.
At the same time, it is preferable to have a step of projecting the support arm 11 of the extruder (actuator) 10 and pushing out the transfer sheet 4 with the tension guide 12. By executing this step, it is possible to apply a strong tension to the transfer sheet 4 to suppress the occurrence of wrinkles.

(4) Fourth Step Next, as shown in FIG. 3, the motor mounted on the rotary moving jig 8 is driven to rotate the transferred object 9 clockwise in the figure. Then, of the transfer foil of the transfer sheet 4, the portion of the roll-shaped engraving 5 in contact with the engraving portion 5a adheres to the side surface of the transfer object 9, so that the transfer sheet 4 is moved upstream in conjunction with the rotation of the transfer object 9. It can be sent from the side to the downstream side. At this time, the rotary moving jig 8 is reciprocated in the front-rear direction while following the shape of the transferred object 9 under the control of the controller. As a result, the contact pressure between the side surface of the transferred object 9 and the engraved portion 5a of the roll-shaped marking 5 is maintained constant, and the rotational force of the transferred object 9 is applied to the roll-shaped marking 5 via the transfer sheet 4. Can be communicated. That is, the roll-shaped marking 5 can be rotated counterclockwise as shown in conjunction with the clockwise rotation of the object 9 to be transferred. Therefore, the transfer foil laminated on the transfer sheet 4 can be transferred (thermally transferred) according to the engraving portion 5a engraved on the roll-shaped engraving 5 over the entire circumference of the side surface of the object to be transferred 9.

For example, when the engraving portion 5a engraved on the roll-shaped engraving 5 is composed of a pattern formed by arranging a large number of star shapes vertically and horizontally as shown in FIGS. 4 and 5, the side surface of the transferred object 9 is formed. As shown in FIGS. 6A and 6B, a large number of star-shaped patterns can be neatly transferred to. Further, as shown in FIG. 7, when the engraving portion 5a engraved on the roll-shaped engraving 5 is composed of the characters as shown in FIG. 6A, the side surface of the transferred object 9 is shown in FIGS. 8A and 8B. Characters can be transferred accurately as in. That is, it is possible to realize clean and accurate transfer without transfer unevenness even on the transferred object 9 having an elliptical tubular side surface.

(5) Fifth Step Since the transfer foil is partially adhered to the side surface of the transfer material 9, the transfer sheet 4 may be temporarily wrapped around the side surface of the transfer material 9 as the transfer material 9 rotates. .. Therefore, the take-up motor 22 is driven for a predetermined time by timer control, and the transfer sheet 4 is forced to travel toward the downstream side. As a result, the transfer sheet 4 wound around the side surface of the transfer material 9 can be wound up by the take-up reel 2, and the transfer sheet 4 can be peeled off from the side surface of the transfer material 9.
Then, by repeating the first to fifth steps, continuous transfer can be performed on the transferred material.

(6) When the engraved portion is a particularly fine character or the like By the way, when the engraved portion 5a of the roll-shaped engraving 5 is a particularly fine character or the like, the transfer sheet 4 in a state where the back tension is applied is covered. When the side surface of the transferred material 9 is pressed against the roll-shaped engraving 5, the side surface of the transferred material 9 is not sufficiently pressed, and the transferred characters or the like are partially damaged or wrinkled, or the roll is rolled. There is a risk that the engraved portion 5a of the shape marking 5 will be damaged.
Therefore, when the engraved portion 5a of the roll-shaped engraving 5 is a particularly fine character or the like, the back tension motor is set to be stopped at the same time as the rotation of the roll-shaped engraving 5 is stopped, and the side surface of the transferred object 9 is set. It is preferable to press-contact the roll-shaped marking 5 and then release the stop of the back tension motor to restore the back tension.
That is, in the first step (initial state), not only the take-up motor but also the back tension motor is set to the non-driving state (stop state) (back tensionless start).

After the following second and third steps, the back tension motor is released from stopping and re-driven to apply a predetermined tension (back tension) to the transfer sheet 4 to relieve the slack generated in the transfer sheet 4. Eliminate (return to back tension).
Further, the support arm 11 of the extruder (actuator) 10 is projected, and the transfer sheet 4 is pushed out by the tension guide 12, and a strong tension is applied to the transfer sheet 4 to suppress the generation of wrinkles.
Subsequently, by performing the fourth and fifth steps, even if the engraved portion 5a is a particularly fine character or the like, the transferred object 9 having an elliptical tubular side surface is formed as in the case of a normal character or the like. On the other hand, it is possible to realize a beautiful transfer without uneven transfer.

Although the configuration of the present invention and its action and effect have been described above with reference to Examples, the embodiments of the present invention are not limited to the above Examples.

For example, in the above description, the case where the rotary moving jig 8 moves in the front-rear direction has been described, but the present invention is not limited to the above embodiment, and the roll-shaped marking 5 moves in the front-back direction. You can also do it. In this case, the rotary moving jig 8 has only a function of rotating the object to be transferred 9. Further, in this case, in the fourth step, the shape of the transferred object 9 is maintained while the rotary moving jig 8 rotates the transferred object 9 and the roll-shaped marking 5 presses the transferred object 9 against the transferred object 9. The transfer foil laminated on the transfer sheet 4 may be transferred to the side surface of the object to be transferred 9 by reciprocating in the front-rear direction (approaching direction and separating direction) while following the above.
If the roll-shaped marking 5 and the heater 6 are configured as an integrated unit U, and the unit U reciprocates in the front-rear direction while following the shape of the transferred object 9 under the control of the controller described above, the roll is always rolled. It is preferable in that it is possible to suppress temperature unevenness that tends to occur in the engraved portion 5a of the shape marking 5.

Further, in the above embodiment, the case of transferring to the elliptical tubular side surface has been described as an example of the object to be transferred, but the case of transferring to the true cylindrical side surface is of course the case, and the rotary moving jig 8 or the roll shape is described. As long as the engraving 5 or the unit U has a step of reciprocating in the front-rear direction so as to follow the shape of the object 9 to be transferred, the same applies to the case of transferring to the side surface of the object to be transferred having another deformed shape such as a polygonal shape. ..

The present invention can be used in a wider range of applications in the field of transfer performed on the side surface of an object to be transferred having a deformed shape such as an elliptical cylinder.
