Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hologram foil feeding device for conveying a hologram sheet.

[Conventional technology]

Hologram foil generally has a structure in which foil plate parts are repeated at regular intervals during manufacturing, and there are foil pass parts where no hologram exists between the foil plate parts. Conventionally, products using holograms include cards, stickers, etc., but there are few examples of continuous use in large quantities, and the presence of the foil pass portion did not pose much of a problem.

However, in recent years, products using holograms have diversified, and there has been a desire for a device to continuously and efficiently use hologram foil in packages for wrapping gifts.

[Problem to be solved by the invention]

Particularly, the present invention provides a hologram foil feeding device used in a foil stamping device that continuously and efficiently stamps hologram foil onto the surface of a package container or the like.

That is, the foil stamping device performs the foil stamping operation while continuously or intermittently supplying blanks, package materials, etc.

However, when pressing the foil, if the foil is stamped while the foil is located on the foil bus part of the hologram foil or on the surface of the package container, etc., the product will be defective.

Therefore, the present invention has been devised for the purpose of providing a hologram foil feeding device that efficiently supplies hologram foil so that the hologram foil is not located at the foil path portion of the hologram foil or on the surface of a package container, etc. .

[Means to solve the problem]

The present invention is a hologram foil feeding device comprising a hologram foil feeding mechanism and a hologram foil feeding amount control mechanism, in which a register mark is provided on the hologram foil and a sensor for detecting the register mark is provided, and the hologram foil feeding mechanism is provided with a sensor for detecting the register mark. consists of a foil feeding roller that can operate at least at two rotational speeds, low speed and high speed, and is driven by a relatively responsive power source. is characterized in that the foil feeding roller is rotated at a high speed, then changed to a low speed, and the foil feeding roller is stopped in response to a detection signal of the register mark during the low speed rotation.

[Effect]

In the feeding of the hologram foil of the present invention, the hologram foil feeding mechanism is operated in conjunction with the foil stamping machine or by a switch at the start, and the hologram foil supported by the foil feeding roller is fed. Then, after feeding out the hologram foil for a certain width (for a certain period of time) at a high speed, the hologram foil feeding speed is changed to a low speed.

Next, when the hologram foil is fed to a predetermined position with a register mark provided for each foil plate portion, a detection signal is generated by the detection device, and the hologram foil feed roller is stopped by this detection signal. Therefore, since the register marks are provided at intervals of one foil section of the hologram foil, the stopping position always remains constant.

Further, since the foil feeding roller is stopped based on the detection of the register mark when the hologram foil feeding speed is low, it works to ensure reliable detection and stopping.

(Example〕 Hereinafter, the present invention will be explained using an example in which the present invention is applied to a foil stamping machine.

As a hologram foil feeding mechanism, hologram foil sheet S
Hologram foil sheet S pulled out from roll 1 wrapped with
The foil is fed through a roller 2 by an iron foil feed roller 3 and two rubber nip rollers 4.

The foil feed roller 3 described above is driven by a foil feed drive motor 5 such as a step motor, and a roller whose speed can be changed to two or more types, low speed and high speed, is used.

Further, the hologram foil sent by the foil feeding roller 3 and the nip roller 4 passes through a plurality of rollers 2 and a registration correction roller 6, and is then supplied between the upper and lower platens 7 of the foil stamping machine shown in FIG.

The register correction roller 6 is movable in the horizontal direction; for example, at the position indicated by the dotted line, the length of the supply to the platen 7 can be adjusted to be shorter than at the position indicated by the solid line. The correction using the register correction roller 6 is particularly useful in correcting the position at the beginning of the foil stamping operation, but it can also be used when changing the position to some extent during the foil stamping operation.

Next, describe the hologram foil feed rate control mechanism. First, the hologram foil sheet S consists of a foil plate portion S and a pass portion P1 provided therebetween for manufacturing purposes, and a register mark 8 is provided near the pass portion P1. After the hologram foil sheet S moves a predetermined amount, for example, at a high speed of about 4/5 of the length of the - foil plate portion, the speed is changed to a low speed.

When the hologram foil is moved at this low speed and reaches the register mark 8 or the foil feed roller 3, the presence of the register mark 8 is detected by the fiber sensor 9 provided close to the foil feed roller 3. do.

This detection signal causes the foil feed roller to stop rotating.

Note that the above-mentioned fiber sensor 9 is connected to the foil feed roller 3.
On the other hand, it is best to provide it at an angle of, for example, about 40 degrees. This is because the register mark 8 is manufactured at the same time as the foil plate portion of the hologram foil, and the above angle is the best for identifying the register mark 8. Further, the reason for setting the position relative to the foil feeding roller 3 is that in this part, the hologram foil is less prone to flapping, wrinkles, etc., and malfunctions can be more reliably prevented. However, the position is not particularly limited as long as it is possible to reliably identify the register mark 8 at a position other than the above-mentioned position. If it cannot be determined, an error detection mechanism is activated and an alarm is issued.

FIG. 2 is a plan view of the hologram foil feeding device of the present invention, and the position of the entire device can be corrected by a foil flow position correction motor 10. The purpose of this foil flow position correction motor 10 is to move the entire unit in the width direction to align the registration position of the hologram foil and the blank 13 on the platen 7 at the beginning of the foil stamping operation.

In the figure, 11 is an encoder, and 12 is a register correction motor.

Further, FIG. 3 shows an outline of the foil stamping machine, and the hologram foil feeding device of the present invention is positioned at the person in the figure. Then, the blank 13 is moved between the upper and lower platens 7, and the hologram foil sent by the foil feeding roller 3 or the like is stamped.

Although the present embodiment is constructed as described above, the foil feeding start timing is controlled manually or by a proximity switch or the like linked to the foil stamping machine.

〔Effect of the invention〕

Since the hologram foil sheet according to the present invention is fed while detecting the register mark on the hologram foil sheet, it is possible to feed the hologram foil sheet while avoiding the pass portion, thereby preventing the hologram foil from being wasted. It has the effect of

In addition, since the product of the present invention can be incorporated into a foil stamping machine to continuously stamp hologram foil, it is possible to automate the foil stamping machine, which enables efficient work, and the structure of the invention itself is simple. It has excellent effects such as being able to be manufactured at low cost.
