Description

[Detailed description of the invention] Gripping device for transferring film from backing tape to substrate The present invention the reel and the take-up reel for the backing tape are arranged in at least two openable halves. Housed in a housing containing housing parts, each reel rotates into the housing. The rewind lock is mounted on a rotating pin located for It is combined with at least one reel, and two rotating pins are produced in the direction of rotation mentioned above. are coupled together via a system of gear teeth including a slip clutch for Also, the backing tape that cannot be wound from the supply reel protrudes from the housing. It is guided by the sticking part that comes out, and the bag is attached on the film side to the above board. Designed to press the king tape, and from the pasting part to the inside of the housing. Returning to the take-up reel, the supply reel and take-up reel are inserted into the housing. The film from the backing tape to the substrate is placed on a support element designed to The present invention relates to a gripping device for transferring.

In such gripping devices, the supply reel and take-up reel are the same as the audio cassette. are arranged adjacent to each other on one surface.

A backing tape coated with an adhesive film on the − side is wound onto a supply reel. On the other hand, the take-up reel is intended to wind used backing tape. ing. The coated backing tape is placed on the substrate where the adhesive is to be applied. It is guided from a supply reel over the applicator to be placed. The above gripping device and the board The relative movement between the adhesives transports the adhesive from the backing tape to the substrate. At the same time, the backing tape that has run out of adhesive is removed by the take-up reel. It is wound up.

One known gripping device (DE-PS37 36 357) has three different It is essentially formed by functional elements. A central intermediate hole that opens at one end. The drive coupling is adapted to the drive coupling between the supply reel and the take-up reel, and The coupling forms a driving coupling between two rotating pins, either directly or through a slip clutch. It is formed by two rotating pins connected to a gear tooth mechanism. closed A replacement cassette is fixedly loaded into this intermediate housing by means of centering means. It is designed to be The above supply reel and take-up reel are in this cassette. The attachment part becomes part of the cassette. ing. In addition, a lip in the form of a spring lip provided on the side wall of the cassette A wind lock is incorporated into the cassette and additionally formed on the take-up reel. Engages the gear rim. Substantially closed housing case with locking lip The third functional element in the form of a housing is a replacement cassette loaded within the intermediate housing. The backing tape is designed to be supported by the In the closed position, only the affixing portion with the taper protrudes beyond the housing case. The above When the housing case is opened to reload the portable device, a replacement casing is The cassette is removed from the intermediate housing and a new cassette is loaded into the housing. is closed again.

Although the operation of this well-known grasping device is relatively simple and error-free, its construction is It is complicated and increases the cost of the equipment. On the other hand, the above equipment has an unnecessarily high consumption of materials It consists of three main functional elements, including:

On the other hand, replacement cassettes - specifically designed not to be reused - require expensive materials. In addition to matching the supply and take-up reels, A rotating pin located in the intermediate housing simply supports the reel on one side. However, since there is no counter support on the housing, this cassette is also This is because it is necessary to ensure safe loading. In addition, the above cassette It must also help form a rewind lock. Replacement cassette of this A complex design unnecessarily increases its retail price solely for reasons of production.

In contrast, the problem addressed by the present invention is its convenience and, in particular, its While maintaining the ease of handling of the The solution was to find a solution by reducing the cost of in-house operations.

According to the invention, this problem is solved because the support element is holder and is fixed between two integrally mating housing halves. It takes the form of a main plate designed to a substantially triangular area having an integral application portion covering the portion and said take-up reel; The rewind lock has a web-like area that supports the At the same time, it is integrated into the half body of the housing facing the gear tooth mechanism. This can be solved by gripping devices of the type mentioned in the introduction.

Through this design, which fully possesses convenience and ease of handling, the above gripping The system is simplified to the extent that production costs can be reduced considerably. the above The gripping device essentially consists of two housing halves that are brought together and these halves. It consists only of a main plate designed to be inserted between the halves of the Uzing. As a result, considerable material savings are possible compared to Nakuchi's gripping device. the above The parent plate supports the take-up and supply reels before they are loaded into the housing. They are essentially only used to hold each other in position and are therefore data does not come into contact with the film being transferred.

After introduction into the housing, the supply reel and take-up reel are installed in both housings. Since the parent plate does not perform any mounting or support functions, the The board has no other function to perform.

In addition, the parent plate is particularly simple and the rewind lock is more easily formed than the parent plate. is formed on the wall of the housing so that the main plate is simply the area of the take-up reel. The fact that the area only needs to include a narrow fixing flange This reduces the amount of materials used.

In a particularly simple embodiment of the invention, the application part tapers into two triangular shapes on the parent plate. It is formed by a transverse wall with a However, other configurations are also possible, of course. It is also possible, for example, for pasting around which a backing tape is guided. A roller may be additionally arranged on the parent plate.

In one particularly preferred embodiment of the invention, the gear tooth mechanism is integrated into the rotating pin. Also, the slip clutch is part of the gear tooth mechanism. This configuration has many parts and simplify manufacturing, resulting in further reductions in manufacturing costs.

The gripping devices simply each have a complete gear toothing mechanism, one connected to the supply reel. two rotating pins, one for the take-up reel and the other for the take-up reel. It only contains.

One particularly advantageous embodiment of the invention provides that the teeth of the rotating pin for the supply reel are formed by a thin-walled neck in the area between the tooth flank and the tooth flank; in the area of the flanks of both rotating pins, in a plane perpendicular to the tooth flanks. If the speed is different due to chamfering, the teeth of the rotating pin on the supply reel may It is characterized by being designed to slide over the teeth of a rotating pin.

This design of a slipping clutch is particularly simple. The above slip clutch is separated directly as a complete part of the gear tooth mechanism, rather than consisting of be. The supply reel's chamfered teeth, which are elastic due to the thin-walled design of the neck, It can slide over the correspondingly chamfered teeth of the rotating pin for the take-off reel. vinegar The response of the slip clutch is controlled through the elasticity of the rotating pin teeth for the supply reel. be able to. The level of elasticity is determined by the design of the neck length and thickness of the thin-walled teeth. and their thin-walled form can be varied as required.

In connection with the slip clutch design, other embodiments of the present invention include Under the chamfered teeth of the rotating bin, the rewind lock faces a gear tooth mechanism. in the form of a correspondingly inclined housing element of the housing halves; As a result, the teeth of the rotation pin can simply slide over the elements of the housing in the direction of rotation. It is characterized by being able to Therefore, the rewind lock prevents malfunction of the device does not require any additional means to provide the The elastic teeth on top slide in the direction of rotation, but in the opposite direction. It is only necessary to provide a housing element with chamfered teeth to prevent .
