Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides characters printed on a belt-shaped transfer paper,
The present invention relates to a device that peels off the transfer paper from the transfer surface of the transfer object after the characters, marks, etc. have been transferred, in a transfer device that transfers marks and the like by pressing them onto the transfer object using a heating plate.

2. Description of the Related Art Transfer devices are well known as devices for writing characters, marks, etc. on the surface of plastic or the like.
As is well known, in this transfer device, characters, marks, etc. to be written on the transfer target are generally printed on thin transfer paper, and after this printed surface is applied to the transfer surface of the transfer target, this transfer is performed. A heating plate is pressed against the transfer surface for a predetermined period of time with the paper in between, and the characters, marks, etc. are transferred onto the transfer surface of the transfer target. When characters, marks, etc. are transferred from the transfer paper to the transfer target in this way, the heating plate is separated from the transfer paper, and a new transfer paper and transfer target are supplied to perform the next transfer. The transfer paper pressed against the transfer target by a heating plate does not necessarily peel off cleanly from the transfer target immediately after the characters, marks, etc. printed on its surface are transferred to the transfer target. This transfer paper peeling work, so-called "foil peeling", has been a factor that hinders the efficiency of the transfer work.

Conventionally, in the transfer work where transfer paper was applied one sheet at a time to an object with a large transfer surface, the pressing operation of the heating plate and the feeding of the transfer paper were all done manually. In the transfer work, even if the foil was removed manually, the reduction in efficiency due to the foil removal work was not so serious considering the overall transfer work. However, in order to process a large number of transfer objects in a short time, the transfer paper is formed into a belt shape, and characters, marks, etc. are printed on it in a continuous manner, and the transfer paper is automatically fed in the longitudinal direction. However, even with a transfer device that automatically reciprocates the heating plate in synchronization, it is necessary to remove the foil, which makes it difficult to take out the transfer target.
In some cases, both feeding and unloading had to be done manually, which significantly reduced the efficiency of the transfer operation. Conventionally, the method for automatically removing foil in this type of device is to place a strip of transfer paper at an appropriate distance from the transfer surface of the transfer target, and when transferring, the transfer paper at this position is placed on a heating plate. The heating plate is pushed and guided to the transfer surface of the transfer target with A method is known in which transfer paper is separated from the transfer surface of an object to be transferred using a tensile force for feeding the paper.

FIG. 1, FIG. 2, and FIG. 3 explain the operation of a transfer device that peels off a transfer paper using such a method. The transfer paper 3 stretched between the transfer object 1 and the heating plate 2 is guided by guide bars 4 and 5 and is sequentially fed in the direction of the arrow under the condition shown in FIG. When the heating plate 2 is pressed against the transfer target 1 with the transfer paper 3 in between and the transfer is completed, the heating plate 2 is returned to the standby position, but the transfer paper 3
remains attached to the transfer surface 6 of the transfer object 1 (FIG. 2). Here, transfer paper 3 is used for the next transfer process.
When the transfer paper 3 is pulled in the direction of the arrow by a winding means (not shown) located on the left side of the figure, the transfer paper 3 is gradually pulled away from the transfer surface 6 from the left side of the figure by the force pulling the transfer paper 3. (FIG. 3), and finally it is completely peeled off from the transfer surface 6 and is tensioned between the guide bars 4 and 5, returning to the state shown in FIG. 1. This type of peeling method is effective when handling transfer objects that have a flat transfer surface, but when handling transfer objects that have a three-dimensional transfer surface, it is difficult to remove the transfer paper well. Sometimes there wasn't. That is, in the area shown by arrow A in FIG. 4, the transfer paper 3
This is because the pulling force cannot act in a direction to separate the transfer paper 3 from the transfer surface 6. In such a case, if the pulling force on the transfer paper 3 is strong enough, the transfer paper 3 may slide on the transfer surface 6 and peel off from the transfer surface 6, but general transfer paper can withstand a large tensile force. The paper is not formed in such a way that it can be easily obtained, and if the binding is strong, the transfer paper is often cut off before it is peeled off from the transfer surface.

The present invention solves the above-mentioned inconveniences, and in the above-described transfer device that uses a belt-shaped transfer paper and a heating plate, even when transferring to a three-dimensional transfer surface, the transfer paper can be automatically removed from the transfer surface. It is an object of the present invention to provide a foil peeling device that can remove foils reliably.

The foil stripping device of the transfer device according to the present invention forcibly separates the band-shaped transfer paper in the direction away from the transfer target, thereby ensuring that the transfer paper is removed even when handling a transfer target with a three-dimensional transfer surface. It is formed so that it can be peeled off from the transfer surface of the transfer target. That is, a foil peeling member that can guide the transfer paper in a direction away from the transfer surface is provided before and after the transfer paper feeding direction of the transfer surface of the transfer target, and the transfer paper that has been transferred is placed on this foil stripping member. The transfer paper is moved in a direction almost perpendicular to the tension direction and to a position away from the transfer surface, and when the transfer paper is separated from the transfer surface, it returns to the original standby position. On the outside of the member, when the foil peeling member moves in the direction of separating the transfer paper from the transfer surface, the transfer paper outside the foil peeling member is pulled by this movement, and the transfer between the foil peeling members is A transfer paper fixing means is provided for fixing the transfer paper so that no force is applied to the paper that would cause it to separate from the transfer surface.

According to the foil peeling device formed in this way, since the transfer target is pulled away from the transfer surface from the two opposing sides on the outside after transfer, the transfer paper has a three-dimensional transfer surface and the transfer paper is pulled away from the transfer surface. Even when the transfer paper is tightly pressed against a three-dimensional transfer surface, the transfer paper can be reliably peeled off from the transfer surface.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 5 shows a portion of a transfer device incorporating a foil stripping device according to one embodiment of the present invention. This transfer device has an oval cross-sectional shape.
This is for transferring a design onto the tank portion of a plastic gas lighter 11, and in order to transfer the design to the rounded part of the tank, the heating plate 12 is placed tightly against the transfer surface with a transfer paper 13 in between. It is formed to have a recess 14 into which it fits (see Fig. 6). Furthermore, a transfer paper presser bar 15 is provided so that the transfer paper 13 can come into close contact with the transfer surface of the plastic gas lighter 11, and this transfer paper presser bar 15 feeds the transfer paper before the heating plate 12 is pressed against the transfer surface. They are pushed down one by one from the front (right side in the figure). Transfer paper 13 is supplied to supply drum 1
6 is wound into a roll and supplied to the winding drum 17.
and two guide rollers 18, 19
The plastic gas lighters 11 are stretched parallel to each other between them. A position detection mark 20 is printed on the edge of the transfer paper 13, and a photoelectric device 21 reads this position detection mark 20 to advance the transfer paper 13 by the length necessary for one transfer. Transfer paper 13
The winding drum 17 that winds up the winding drum 17 is driven by a motor 22. This motor 22 is configured to be electromagnetically braked, and the rotation of the winding drum 17 can be locked at will. The supply drum 16 is not driven, but is configured such that its rotation is locked by an electromagnetic clutch 23.
The pedestal 24 is provided with eight recesses 25, and the eight plastic gas lighters 11 are housed in the recesses 25 to take a predetermined position relative to the transfer paper 13. Although not shown in the figure, these eight plastic gas lighters 11, which are the objects to be transferred, are automatically supplied to the pedestal 24 by a known technique, and are automatically discharged from the pedestal 24 after the transfer is completed. . Slit-shaped openings 26, 26 are provided on both the left and right sides of the pedestal 24 to allow the transfer paper 13 to pass through.
Foil peeling members 27, 27a having a are provided,
These two foil stripping members 27, 27a are movable in the vertical direction in the figure by an air cylinder (not shown).

Next, a mechanism for performing foil peeling in the above-described apparatus will be explained. FIG. 6 shows a state in which the transfer paper 13 is peeled off from the eight plastic gas lighters 11 by the foil peeling members 27, 27a and then wound up in the direction of the arrow for the next transfer process. be. In other words, at this time, the foil peeling members 27, 27a are releasing the transfer paper 13,
The transfer paper 13 is inserted into the opening 2 of the foil peeling member 27, 27a.
6, move freely within 26a. When the transfer paper 13 is fed by a predetermined amount (FIG. 7), the transfer paper presser bar 15 is moved onto the winding drum so that the pattern 28 printed on the transfer paper 13 is brought into close contact with the transfer surface of the plastic gas lighter 11. The numbers closest to 17 are pressed down in sequence. At this time, the foil stripping member 27 that is closer to the winding drum 17 is attached to the transfer paper presser bar 15 that is the most forward in the transfer paper feeding direction, and the foil stripper 27a that is closer to the supply drum 16 is attached to the transfer paper presser bar 15 that is the most rearmost in the transfer paper feeding direction. and move downward to prepare for the next foil peeling operation (8th
figure). Thereafter, the heating plate 12 is pressed against the transfer surface of the plastic gas lighter 11 with the transfer paper 13 in between for a predetermined period of time, and then returned to its original position. When the heating plate 12 returns to its original position, the aforementioned motor 22
The rotation of the winding drum 17 and the supply drum 16 is locked by the electromagnetic clutch 23, and the transfer paper presser rod 1
5 and the foil peeling members 27, 27a are raised up and down,
The transfer paper 13, which was located between the two foil stripping members 27 and 27a and was in close contact with the transfer surface of the plastic gas lighter 11, is forcibly pulled upwards by the two foil stripping members 27 and 27a. Figure 9)
Eventually, it peels off from the transfer surface of the plastic gas lighter 11 (FIG. 10). When the transfer paper 13 is peeled off from the transfer surface, the winding drum 17 and the supply drum 16
is unlocked. In this way, the same operation is repeated.

In the embodiments described above, the foil peeling member is formed to have a slit-like opening and guide the transfer paper, but essentially it can be used to move the transfer paper away from the transfer surface. For example, a rod or the like formed so as to move in the same manner as the foil peeling member of the above-described embodiment may be used when it is passed over the side of the transfer paper to be transferred. Further, the transfer device in the above example is equipped with a transfer paper presser bar, and the foil stripping member is formed to operate in conjunction with the movement of the transfer paper presser bar, but the foil stripping device according to the present invention is Of course, the use is not limited to this type of transfer device; for example, a transfer device that brings the transfer paper into close contact with a three-dimensional transfer surface using only the recesses provided in the heating plate, and even general use. It is also effective when used in a transfer device that transfers to a transfer target having a planar transfer surface. Even in a transfer device in which a transfer paper presser bar is used, it is not necessarily necessary to operate the foil stripping member and the transfer paper presser bar in conjunction with each other as in the above example; If you use a peeling member, you won't have to pull down the transfer paper when the foil peeling member lowers to the standby position.
It is sufficient if the transfer paper presser bar is independently withdrawn prior to its descent. In such a case, the foil peeling members before and after the transfer target can be integrally formed. Furthermore, the means for fixing the transfer paper is not limited to the locking of the winding drum and the supply drum in the above embodiments, but may include mechanically sandwiching the transfer paper, or rotation of the winding drum and supply drum. may be formed to be appropriately heavy so that the transfer paper does not rotate even if it is pulled by the foil peeling member.

The foil stripping member must be able to guide the transfer paper away from the transfer surface at least to the point where the transfer paper can be separated from the entire surface of the transfer surface when stripping the foil. Therefore, when performing transfer using multiple pieces, if the number of pieces is large or the three-dimensional shape of the object to be transferred is complex, the transfer paper may be bent between the foil stripping members and the transfer may be difficult. In such a case, the movement stroke of the foil peeling member will inevitably be set to be long.

As explained above, if the foil stripping device of the present invention is used, foil stripping for each transfer process can be performed extremely reliably, so that the transfer target can be automatically supplied and removed. It becomes possible to transfer a large number of transfer objects in a short time, and the efficiency of transfer work is greatly improved.
