Description

Detailed Description of the Invention [Field of Industrial Application] The present invention provides a protective paper for transporting parts whose surfaces are covered with protective paper, peeling off the protective paper, and automatically supplying only the parts to an assembly position. The present invention relates to a method and apparatus for peeling off.

[Conventional technology]

For parts that have been polished to a mirror or near-mirror surface, protective paper may be pasted on the surface to prevent scratches, dirt, or stains from forming on the surface, and this protective paper may be removed during final assembly. It is being done. However, since this protective paper adheres to the surface it is protecting, it is surprisingly difficult to remove.
In addition, the surface of the protective paper must not be scratched or stained during or after the protective paper is removed, so the work of peeling off the protective paper and assembling the product must be done by hand, and must be done carefully. It was hot.

[Problem that the invention seeks to solve]

The present invention aims to provide a method and apparatus for automating the work of peeling off the protective paper and supplying it to the assembly position, which has conventionally been done manually.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention extends the adhesive tape from a payout reel holding the adhesive tape wound into a roll to a take-up reel via at least one idle roller and a small diameter peeling roller. It has a tape feeding device that sequentially feeds the tape, and a parts feeding device that sticks the parts together with the protective paper on the adhesive tape between the idle roller and the peeling roller, and bends the adhesive tape at a steep angle to paste the parts together with the protective paper. The idle roller, the peeling roller, and the take-up reel are arranged at an acute angle so that the product can be peeled off.
The protective paper of a component whose surface is covered with protective paper is attached to a strip of adhesive tape together with the component, and the adhesive tape is bent at a steep angle using a small-diameter peeling roller to peel off the protective paper together with the adhesive tape. This method uses a method in which the protective paper is peeled off from the parts.

〔Example〕

Hereinafter, the present invention will be explained based on Examples.

FIG. 1 is a front view of a device for peeling off protective paper on both sides of a thin plate-like component, in which a large number of components 2 whose both sides are covered with protective paper are stacked in a magazine 1, and an optional escapement (not shown) is shown. This allows them to be taken out one by one.

The adhesive tapes 3 and 4 are wound into rolls and attached to feed-out reels 5 and 6, passed through idle rollers 7 and 8, bent at a sharp angle by a small diameter peeling roller 9, or folded into the idle roller 1.
0 and 11, are bent at a sharp angle by a small-diameter peeling roller 12, and wound onto a take-up reel 13 or 14, respectively. Here, the feed reel 5,
6. The idle rollers 7, 8, 10, 11 and the peeling rollers 9, 11 are driven by a drive device (not shown) and constitute a tape feeding device that feeds the adhesive tapes 3, 4, respectively. The angle formed by the peeling roller 9 and the take-up reel 13 or the idle roller 11, the peel roller 12 and the take-up reel 14 is the same as that of the peel roller 9 or 1.
It is arranged at an acute angle so that it can be bent at a sharp angle at position 2. Adhesive tape 3, 4 between idle roller 8 and peeling roller 12
are arranged at narrow intervals, facing each other with their adhesive surfaces facing inside, and are stretched parallel to each other or with the interval gradually becoming narrower, and are fed synchronously.

Below the magazine 1 is a first parts supply device 15.
The parts separated one by one by the escapement of the magazine 1 are held by an arbitrary chuck (vacuum chuck 16 in this example) and conveyed to the lower part of the adhesive tape 3, and then ascended to the adhesive tape. Paste it by pressing it on. A backup plate 17 is provided above the adhesive tape, and the chuck 16 of the first component supply device 15 and the backup plate 1 are provided on the top of the adhesive tape.
The parts to be pasted are sandwiched together with the protective paper between the adhesive tape 7 and the adhesive tape 3, and sufficiently pressed, so that the parts are securely pasted on the adhesive tape 3 through the protective paper.

The adhesive tapes 3, 4 are fed synchronously at the same speed and at opposite positions, i.e. on the back side of each adhesive tape 3, 4 between rollers 11 and 12 in the embodiment shown in FIG. 1 presser plate for each
8, 19 (Fig. 2) and a guide plate 20 are provided, and the presser plates 18, 19 are biased toward the guide plate 20 by an arbitrary spring load, and work together with the guide plate 20 to prevent adhesiveness. The parts sandwiched between the tapes 3 and 4 are pressed together to securely adhere to the protective paper on both sides, and the guide plate 20 guides and supports this integrated tape.

FIG. 2 is an enlarged view of section A in FIG. 1. A second component supply device 21 is provided at the end of the adhesive tapes 3 and 4.
is provided. The second component supply device 21 has a transport table 23 on which a component from which the protective paper has been peeled is placed, held lightly by claws 22 and transported, and is guided by two guide shafts 24 to slide. Reference numeral 25 denotes a third component feeding device for transporting components to a side standing position, and in this embodiment, it is composed of a soft and smooth member 26 that does not damage or stain the surface of the component from which the protective paper has been removed. However, other means such as a mechanical chuck that grips only the outer periphery can be used depending on the shape of the part, the range to be protected, etc.

Next, the operation will be explained in place of the explanation of the peeling method.

The parts 2 stacked in the magazine 1 and covered with protective paper on both sides are separated from the lower end by a piece-by-piece escapement and held in a vacuum chuck 16 of a feeding device 15. The component held by the vacuum chuck 16 is conveyed below the adhesive tape 3, and the feeding device 15 rises to press the component and the adhesive tape 3 together. At this time, as described above, the component and the adhesive tape 3 are sandwiched between the chuck 16 and the backup board 17 so that the component and the protective paper are reliably attached to the adhesive tape. The parts attached to the adhesive tape 3 move as the tape is fed, and are fed into the narrow gap between the lower adhesive tape 4 and the pressure plate 18 and the guide plate 20. will be firmly attached. When the adhesive tapes 3 and 4 that adhered the parts to the center are further fed and reach the position of the peeling rollers 9 and 12, the adhesive tapes are bent at a steep angle, so that they are peeled off from the parts with the protective paper still attached. Take-up reel 13,1
4, the parts only go straight and are inserted into the second parts supply device 21, and as the second parts supply device moves forward, they are conveyed to the lower part of the third parts supply device 25, and then The components are transported and supplied to the assembly position by the component supply device 25 of No. 3.

FIG. 3 is a front view of an apparatus for peeling protective paper from a component having protective paper on only one side.

The structure related to the upper adhesive tape 3 is almost the same as that of the first embodiment shown in FIG. 1, so the same reference numerals are given and the explanation will be omitted here.

Below the adhesive tape 3, an arbitrary conveyor device (belt conveyor 27 in this embodiment) is connected to the parts 28.
They are spaced apart by a distance corresponding to the height of , or by a slightly narrower distance. The belt conveyor 27 has a conveyor belt 31 stretched between two pulleys 29 and 30, and is driven in the direction of the arrow in synchronization with the adhesive tape 3 by a drive source (not shown).
By providing suitable backup members on the back surfaces of the adhesive tape 3 and the belt 31, the adhesive tape 3 can be reliably pressed against the parts.

Furthermore, in order to easily insert the parts on the conveyor belt under the adhesive tape, the idle roller 8 may be configured to be movable up and down and biased downward, or the position of the idle roller 8 may be configured to be biased downward. It is preferable to keep the distance apart from the height of the component and to gradually narrow the distance toward the peeling roller 9.

An optional feeding device (not shown) feeds the component 28 whose top surface is covered with protective paper. The parts are fed by a conveyor 27 that feeds the adhesive tape towards the adhesive tape 3 at the position of the idle roller 8.
The protective paper on the upper surface is stuck to the adhesive tape 3 and is further fed by the belt 31. Since the adhesive tape 3 is bent at a sharp angle at the position of the peeling roller 9, the protective paper is peeled off from the component 28 along with the adhesive tape 3 as described above, leaving only the component 28 on the conveyor and being further fed.
is gripped by the chuck 26 and supplied to the assembly position.

〔Effect of the invention〕

As described above, the present invention conveys the parts covered with the protective paper and attaches the protective paper to the adhesive tape at the end of the conveyance position and peels it off.Therefore, there is no need to manually peel off the protective paper, which saves assembly labor. This has a great effect on the Further, according to this device, the entire device can be made compact with a simple component supply device, an idle roller, a peeling roller, and a take-up reel.
