JPH10250290A - Feeding and winding mechanism for transfer tape of coating applicator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To smoothly and steadily feed or wind a transfer tape in a delivery reel and a winding reel in a coating applicator. SOLUTION: This feeding and winding mechanism comprises an elastic frictional unit 11 such as a rubber ring provided at one outer circumference of clutches 9, 10 integral with a delivery reel 5 and a winding reel 6. In this case, surfaces of the clutches 9, 10 are cooperated and rotatably brought into close contact with one another to feed or wind a transfer tape 4. Thus, the rotary force of the delivery reel side is effectively transmitted to the winding reel side to steadily deliver or wind the tape by absorbing an impact by the frictional unit.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer tape to which a paint or an adhesive (hereinafter referred to as "paint") adheres to a surface of an object to be transferred while sliding the paint or the like. Coating tools that are transcribed and corrected for errors, etc.
In particular, the present invention relates to a mechanism for feeding and winding a transfer tape in an applicator main body.

[0002]

2. Description of the Related Art Conventionally, an applicator which transfers a paint or the like by sliding a transfer tape having a paint or the like adhered to the surface thereof in close contact with an object to be transferred and corrects erroneous writing or applies an adhesive. In the mechanism for sending and winding the transfer tape in the above, the gear integrated with the sending reel for winding the unused transfer tape and the gear integrated with the winding reel for winding the used transfer tape are mutually separated. The transfer head, which is engaged and protrudes from the opening of the applicator main body and is fixed, and slides while keeping the transfer tape in close contact with the surface of the transfer object, allows the unused transfer tape to be sent out from the delivery reel. Since the gear that is integrated with the sending reel also rotates by being sent out toward the transfer head by the rotation of the reel, the gear that is integrated with the sending reel meshes with the gear that is integrated with the sending reel. The gear integrated with the take-up reel rotates in the opposite direction, so that the take-up reel integrated with the gear also rotates in the same direction, so that the used transfer tape can be taken up by the take-up reel. It is generally wound up.

[0003]

However, unlike the above-mentioned conventional device, the gears integral with the sending reel and the take-up reel are rotated together with the reel in opposite directions so as to interlock with each other. In the case of sending the used transfer tape and winding the used transfer tape, the gear integrated with the sending reel and the take-up reel can easily rotate with respect to the shaft inside the applicator body. When a large impact is applied to the applicator by dropping or the like, it is integrated with the delivery reel and the take-up reel, which are loosely fitted on the shaft inside the applicator main body. The gear that swings greatly, and in the worst case, both gears that mesh with each other are disengaged, and the delivery reel and take-up reel in the applicator body rotate in conjunction with each other. It is impossible to send unused transfer tape from the sending reel and take up the used transfer tape to the take-up reel at all, so that it cannot be used as an applicator. .

In addition, it is necessary to wind the used tape in a tensioned state by setting the rotation speed of the reel on the winding side higher than the rotation speed of the reel on the sending side. If the sliding mechanism is not provided, the tape may be cut by an excessive tensile force. As the sliding mechanism, there is an O-ring, a spring, or a mechanism utilizing friction between parts. May occur. Further, in transmitting and winding the transfer tape, the transmission power of the sending reel and the take-up reel is transmitted through meshing of both gears integrated with the sending reel and the take-up reel. When the reel and the take-up reel rotate, the gears that mesh with each other integrally with the two reels are liable to be worn or damaged due to the striking of the gears. In this case, noise and idle rotation are caused to hinder a smooth application operation, which is very troublesome for a user, and causes a problem of lowering usability as an application tool.

The present invention has been made to solve the above-mentioned drawbacks and problems of the prior art.
The winding can be performed smoothly and quietly.

[0006]

For this purpose, in an applicator for transferring a paint or an adhesive on a transfer tape and correcting or adhering erroneous writing, the applicator is rotatable in cooperation with each other in the applicator body. An elastic friction body such as a rubber ring is provided around the outer periphery of at least one of the large-diameter clutch on the sending side and the small-diameter clutch on the winding side, which are integrated with the sending reel and the take-up reel. By bringing the clutches of the take-up reel into close contact with each other, both the delivery reel and the take-up reel which are integrated with the clutches rotate in the opposite directions in conjunction with each other, and perform delivery and winding of the transfer tape. .

[0007] Further, in the applicator main body, the outer periphery of at least one of a delivery reel that rotates in the opposite direction in conjunction with each other to feed and wind the transfer tape and a clutch that is integral with the take-up reel. Protrusions such as grooves are appropriately provided on the surface of an elastic friction member such as a rubber ring provided around the periphery of the transfer tape. When an elastic friction member such as a rubber ring is provided around one of the clutches integrated with the sending reel and the take-up reel, the concave and convex portions such as grooves are appropriately formed on the surface of the other clutch. It is made.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In practicing the present invention, by using a transfer tape, a delivery reel rotates in synchronization with the delivery of the transfer tape, and a large-diameter clutch integrated with the delivery reel also rotates. Therefore, the large-diameter clutch and the clutch integrated with the small-diameter take-up reel, whose surface is in close contact with an elastic friction member such as a rubber ring, also rotate in the opposite direction, and the used transfer tape is removed. At this time, the clutches integrated with the sending reel and the take-up reel are in close contact with each other via an elastic friction body such as a rubber ring. In addition to the close contact, the contact and the continuous winding without the interposition of the O-ring and the spring can be performed smoothly and quietly. Here, the elastic friction body is not limited to rubber, but may be leather, cloth, or a band body coated with a viscous material that generates a certain amount of friction. It may be formed by.

In addition, irregularities such as grooves are appropriately formed on the surface of an elastic friction member such as a rubber ring provided around at least one of the clutches integral with the sending reel and the take-up reel. In the case where an elastic friction body such as a rubber ring is provided around one outer periphery of the clutch integrated with the take-up reel, a rubber ring or the like is formed by appropriately projecting irregularities such as grooves on the surface of the other clutch. The elasticity between the elastic friction bodies makes it possible to adhere more reliably, so that the sending and winding operations can be performed more smoothly and quietly, and it is provided around the outer periphery of the clutch by long-term use. Even if the surface of the elastic friction body such as a rubber ring is worn, the minimum friction can be secured, so that the transfer tape can be sent and wound. In addition,
Unless the diameter of the clutch integrated with the sending reel is larger than that of the winding side, the rotation cannot be smoothly transmitted to the winding reel.
