Description

Coating film transfer head assembly and coating transfer device

The present invention relates to a coating film transfer device for transferring a transfer layer of a transfer belt to a surface to be transferred, and a head assembly for the coating film transfer device.

In the past, a coating film transfer tool suitable for a correction tape or a tape glue or the like has been provided. For example, Japanese Laid-Open Patent Publication No. 2000-37991 discloses a coating film transfer device in which a transfer portion having a blade shape is provided and a roller is provided on the upstream side of the transfer portion. Since the coat film transfer device feeds the transfer belt by the roller on the upstream side, the transfer operation can be easily performed. In the same manner as disclosed in Japanese Laid-Open Patent Publication No. Hei 10-236081, a transfer film having a blade-shaped transfer portion and a roller on the upstream side of the transfer portion is disclosed. On the roller of the coating film transfer device, a crotch portion having a circular shape in a side view is formed at both ends. The side edge of the transfer belt is guided by the crotch portion and simultaneously conveyed to the transfer portion.

In the coating film transfer device of JP-A-2000-37991, not only in the blade-shaped transfer portion but also on the roller on the upstream side of the transfer portion, the transfer belt is abutted to be Since the transfer surface is transferred to the transfer portion of the blade shape before the transfer, the roller may be transferred. In this case, the user is allowed to perform transfer on the transferred surface which is not intended to be transferred. Further, since the transfer belt is pressed by both the roller and the transfer portion, there is a case where the user cannot sufficiently apply the pressing force to the transfer portion during the transfer operation, and in this case, there is a case where turn Bad printing happened. Further, the transfer belt generates excessive tension between the transfer portion and the roller, and there is a problem that the transfer of the coating film is negligent.

Further, in the coating film transfer device of Japanese Laid-Open Patent Publication No. Hei 10-236081, the transfer belt is positioned between the crotch portions provided at both end portions of the roller and having a circular side view, and is further transported to the transfer portion. . The crotch portion is in contact with the surface to be transferred, thereby rotating the roller. Therefore, the roller system is separated from the surface to be transferred, so that it is not transferred by the roller. However, the transfer belt is in contact in the width direction of the roller. At this time, due to the speed difference between the outer circumference of the crotch portion and the outer circumference of the roller when the coating film transfer device travels, the transfer speed of the transfer belt cannot be synchronized with the rotation of the roller, which occurs in the transfer belt and the roller. Excessive tension is generated between the transfer belts. In this way, not only the transfer operation of the transfer film transfer device becomes laborious, but also the transfer portion of the transfer belt from the blade-shaped transfer portion may be detached, or the operation of the coating film transfer device may occur.

That is, the side roller trains are disposed as the side guide member 34 and the drive member 35, respectively, at two locations outside the side edges of the transfer belt T. Further, the support shaft of the side roller, that is, the side guide member support shaft 31k rotatably supporting the side guide member 34, and the drive shaft 33a of the fixed drive member 35 are disposed to be separated from the transfer belt T .

Next, the operation at the time of the transfer operation of the coat film transfer device 10 will be described. As shown in FIG. 6, when the coat film transfer device 10 is pulled rearward, the transfer belt T is transferred toward the transfer by the transfer roller 36b which abuts against the bulging portion 36 of the transfer belt T from the back surface. The protruding portion 31g is sent out. Further, while this operation is being performed, the transfer belt T is pressed by the transfer projection 31g to the transfer surface S so that the transfer layer provided on the surface of the transfer belt T is transferred onto the transfer surface S.

At this time, the coat film transfer device 10 is stably and straightly moved rearward by the side guide member 34 and the drive member 35 which are side rollers. Further, since the transfer belt T is conveyed toward the transfer projection 31g by the conveyance roller 36b, an easy pulling feeling can be achieved. Further, by the transfer projection 31g, the transfer layer of the transfer belt T can be surely transferred to the transfer surface.

Further, since the outer diameter D1 of the drive wheel 35b (see FIG. 8(a)) is slightly the same as the outer diameter D2 (see FIG. 8(a)) formed on the upper surface side of the truncated cone-shaped transfer roller 36b, the drive can be made The speed of the outer circumference of the wheel 35b is slightly the same as the speed of the outer circumference of the conveying roller 36b. On the other hand, the speed at which the transfer belt T is transported (hereinafter also referred to as "transfer speed") is formed to be slightly the same as the speed of the outer circumference of the drive wheel 35b that is grounded to the transfer surface S. Therefore, since the speed of the outer circumference of the conveying roller 36b is slightly the same as the conveying speed of the transfer belt T, the conveying roller 36b can surely convey the transfer belt T to the transfer projection 31g side.

Further, although the drive wheel 35b is inclined to be in contact with the transfer surface S in FIG. 5, since the drive wheel 35b is formed of a soft enamel material, it can be rotated in close proximity to the transfer surface S.

The transfer belt T transferred by the transfer projection 31g climbs up on the front surface 31g2 of the transfer projection 31g, and is guided along the curved surface 31c while being guided by the guide projections 31d and 31e. It is taken up to the inside of the casing body 5. At this time, due to the front surface and the curved portion of the transfer projection 31g The connecting portion between the curved surfaces 31c is continuously formed, so that the transferred transfer belt T can be smoothly taken up.

Further, the head body 31 is supported to be rotatable relative to the head support 32. Therefore, as shown in FIG. 6, the cover body 5 can be tilted to perform the transfer operation with respect to the transfer surface S, and as shown in FIG. 7, the case body 5 can be raised and rotated with respect to the transfer surface S. Printing operation.

At this time, the rotation center Q constituted by the head rotation shafts 31a, 31b and the rotation support holes 32b1, 32c1 is positioned at the contact point P of the transfer projection portion 31g and the rotation center of the drive member 35. The intermediate point between C is also close to the transfer projection 31g, so that even if the case body 5 is at any angle with respect to the head body 31 (i.e., either in the case of Fig. 6 or in the case of Fig. 7) Next, the pressing force transmitted from the case body 5 will be applied to the transfer protrusion 31g with more force than the drive member 35 (and the side guide member 34). Therefore, even if the casing main body 5 performs the transfer operation at any angle with respect to the transfer surface, the adhesion of the transfer layer due to insufficient pressing force to the transfer projection 31g can be reduced.

Next, a modification of the belt member 33 will be described with reference to Figs. 8(b) to 8(d). It is to be noted that the same members and the same parts as those of the belt member 33 of Fig. 8(a) are denoted by the same reference numerals, and the description thereof will be omitted or simplified. The belt member 133 of Fig. 8(b) is formed by changing the bulging portion 36 of the belt member 33 of Fig. 8(a), and the formed bulging portion 136 is formed into a ring shape which is rounded to the edge portion. . The bulging portion 136 is formed of a soft material such as a tantalum material or a thermoplastic elastomer, and is fixed to the drive shaft 33a by gluing or two-color molding or the like. The outer diameter of the bulging portion 136 is set to be slightly the same as the outer diameter of the driving member 35.

The belt member 233 of Fig. 8(c) is formed by changing the bulging portion 36 of the belt member 33 of Fig. 8(a), and the formed bulging portion 236 is configured to have a polygonal shape when viewed from the side. The bulging portion 236 is also formed of a soft material such as a ruthenium material or a thermoplastic elastomer, by means of a glue. It is fixed to the drive shaft 33a by a two-color molding or the like. The outer diameter of the bulging portion 236 is also set to be slightly the same as the outer diameter of the driving member 35.

Further, in the belt member 233 of Fig. 8(c), the guide roller 238 that guides the transfer belt T is fixedly disposed on the drive shaft 33a between the drive member 35 and the bulging portion 236. In this manner, a member that guides the transfer belt T other than the driving member 35 may be provided.

The belt member 333 of Fig. 8(d) is replaceable with the belt member 33 and the side guide member 34 (see Fig. 5) of Fig. 8(a) and is provided in the head body. The belt member 333 is provided with a drive shaft 333a. The drive shaft 333a is formed by a main shaft 333a1 and an end shaft 333a2. The main shaft 333a1 is formed to be larger than the outer diameter of the end shaft 333a2. A drive member 35 is fixedly disposed at the left end of the main shaft 333a1. On the other hand, at the right end of the main shaft 333a1, a portion which is connected to the end shaft 333a2 is formed with a bulging portion 336. The bulging portion 336 is also formed of a soft material and is fixedly disposed on the drive shaft 333a.

The bulging portion 336 is formed in a truncated cone shape. On the other hand, the diameter of the bulging portion 336 corresponding to the upper surface of the truncated cone shape is set to be the same as that of the driving wheel 35b. Further, the angle of the bulging portion 336 with respect to the axis L of the drive shaft 333a and the bulging portion 336 toward the right is set to an angle α .

Further, a side guide member 334 is provided on the end shaft 333a2. The side guide members 334 are formed in a circular shape and loosely fitted to the end shafts 333a2. That is, at the side guide member 334, the rotational force from the drive shaft 333a will not be transmitted. Further, the diameter of the side guiding member 334 is formed to be larger than the diameter of the driving wheel 35b.

The belt member 333 thus formed is rotatably provided to the head body such that the side guide member 334 and the drive wheel 35b are in contact with the transfer surface S. Here, the outer diameter of the side guiding member 334 is larger than the outer diameter of the driving wheel 35b. Therefore, the drive shaft 333a is obliquely provided to the head body in a state in which the side guide member 334 side (i.e., the right side) is raised. At this time, the transfer belt T at the position of the bulging portion 336 does not come into contact with the transferred surface S. In other words, the bulging portion 336 is separated from the transferred surface S. In the present embodiment, the angle at which the axis L of the drive shaft 333a is inclined with respect to the surface to be transferred S is set to an angle α . Therefore, the lower end edge of the bulging portion 336 in the front view is formed in parallel with the transfer surface S. That is, the bulging portion 336 abuts in parallel with the back surface of the transfer belt T.

As a result, as shown in FIGS. 8(a) to 8(d), the bulging portion formed by bulging from the drive shaft can be set in various shapes. Further, the bulging portion is formed by bulging from the driving shaft, and is capable of abutting against a part of the back surface of the transfer belt T. Therefore, since the surface pressure of the abutting portion can be increased as compared with the case where the transfer belt T abuts in the width direction, the transfer belt T can be more reliably conveyed to the transfer projection portion 31g side.

The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and may be implemented in various aspects. For example, another type of belt member may be used, and the driving member that is in contact with the surface to be transferred S and that rotationally drives the drive shaft may be a separate element from the drive shaft provided for the bulging portion. In this case, a transmission mechanism is provided for transmitting the rotational force of the drive member to the drive shaft provided for the bulging portion.

Further, in the present embodiment, the transfer protrusion 31g is disposed on the front side of the head body 31, and the belt member 33 is disposed on the rear side. That is, the belt member 33 can be disposed on the front side of the head body 31, and the transfer protrusion portion 31g can be disposed on the rear side. In this case, the used transfer belt T is conveyed to the case body 5 in a pulled state by the belt member.

Further, the mounting position of the side guide member 34 in the front-rear direction is not limited. However, in order to obtain a more stable straightness of the coat film transfer device 10, it is preferably provided at a position opposed to the driving member 35.

Further, the side roller in the present embodiment is formed by the side guide member 34 and the driving member 35, and is disposed in the vicinity of the side edge of the transfer belt T, but is not limited thereto, and may be disposed in The side edge of the transfer belt T is sufficiently far away from the outer edge.

Further, the belt member 33 may be disposed in parallel with the transfer surface S, and the bulging portion 36 is designed as a bulging portion having a smaller outer diameter than the driving member 35 and the side guiding member 34.

In the present embodiment, the transfer projection 31g is formed in a slightly triangular shape in a side view. However, the present invention is not limited thereto, and various shapes such as a blade portion having a thin plate shape at the tip end may be used.

Further, in the present embodiment, the head rotating shafts 31a and 31b are provided in the head main body 31, and are engaged with the swivel support holes 32b1 and 32c1 of the head support body 32, and the head main body 31 is formed in the front-rear direction. The rotation is performed, but the relationship between the aforementioned shaft and the hole can also be adjusted.

The embodiments described above are described by way of example and are not intended to limit the scope of the invention. The present invention can be implemented in various other forms, and various omissions, substitutions and changes can be made without departing from the scope of the invention. The embodiments and the modifications thereof are included in the scope of the invention and the scope of the invention as set forth in the appended claims.
