Description

Description: TECHNICAL FIELD The present invention relates to a method for automatically sticking a double-sided adhesive tape to one article to be mutually bonded in a state of being peeled from a mount, and a sticking device used for the same. For example, it is suitably used as a sticker for various small articles such as a mirror adhered to a compact case for makeup.

(Prior art and its problems) Double-sided adhesive tapes have been widely used in recent years for adhesion of various small articles because they are easy to handle and do not require drying and curing unlike liquid adhesives, but they are generally used for release. Since it is provided as a roll that is wound in the form of being attached to the sex mount, it is necessary to peel off the mount when adhering.

However, when the tape is cut together with the mount according to the size of the article to be bonded, the mount will be peeled before the article to which the cut piece is attached is joined to the article to be bonded. Since the operation is mechanically extremely difficult to automate, there is no choice but to rely on inefficient manual work, which seriously hinders mass productivity and raises the manufacturing cost.

Therefore, in order to deal with the above problem, only the adhesive tape layer of the double-sided adhesive tape with a mount is preliminarily cut, and each of the cut adhesive tape layers having a predetermined length is peeled and transferred from the mount onto the article to mount the mount. Although a method of winding up is conceivable, conventionally, a practical means capable of reliably, automatically and continuously performing the operations from cutting to transferring by a simple device configuration has not been found. The reason for this is that if the above-mentioned cutting is incomplete, the adhesive tape layer to be transferred and the next adhesive tape layer are continuously peeled off from the mount, and if it is cut to the mount, it becomes impossible to wind up. It is necessary to set the cutting depth at the cutting portion with extremely high precision and invariant,
In general, in addition to requiring a highly precise and complicated cutting mechanism, it is not easy to reliably transfer the adhesive tape layer from the backing paper onto the article by timing both the cutting and transfer operations. Above, it is easy to adhere to the next adhesive tape layer subsequent to the adhesive tape layer corresponding to one article surface, or the adhesive tape layer corresponding to one article surface tends to adhere over the next article surface, This is because it is difficult to prevent the next adhesive tape layer from adhering when it is necessary to attach the adhesive tape layer to only a part of the surface of the article.

(Means for Solving the Problem) In view of the above-mentioned circumstances, the present invention is to automatically and continuously and reliably in a state where a double-sided adhesive tape is peeled from a mount on one article to be mutually bonded by a simple device configuration. It is an object of the present invention to provide a sticking method and a sticking device that enable efficient sticking to a skin.

That is, the sticking method of the double-sided adhesive tape of the present invention, in order to achieve the above-mentioned object, the double-sided adhesive tape with a mount is intermittently run at a sticking position via a sticking roller, and a fixed position is provided at each stop period of this running. While the disc blade is rolled under pressure by the spring force to cut only the adhesive tape layer in the width direction while leaving the backing paper, one work is independently fed to the attaching position for each cycle of this intermittent running. The work is pressed against the sticking roller side and pressed against the front end of each adhesive tape layer divided by the above cutting, and the pressed work is synchronized with the tape during the running period of the tape. And moving in a direction in which the adhesive tape layer is separated from the mount, each adhesive tape layer is transferred from the mount to the work and before the rear end of the adhesive tape layer contacts the work. It is characterized in that for separating the workpiece from the application roller.

Further, the sticking device of the present invention applied to the above-mentioned method includes a sticking roller that is in contact with the mount side surface of the double-sided adhesive tape with a mount and is in contact with the surface of the tape on the mount side, and a tape on the front side of the running of the sticker roller. An intermittently rotating drive roller that pulls the mount and runs the tape intermittently, a cutting cradle that has a flat surface that abuts the mount side surface of the tape on the running rear side of the pasting roller, and on this cradle A disc blade that reciprocally rolls across the tape in the width direction, a reciprocating driving means for the disc blade, a spring member capable of adjusting a spring force that presses the disc blade against the surface of the pedestal, and a holding position of the disc blade are set to the tape. Disc blade holding position displacing means for displacing in the running direction of the tape, work supplying means for independently feeding one work to the pasting position for each cycle of the intermittent running of the tape, and grasping the work at the pasting position. Chucking mechanism, a detaching / attaching operation means for operating the grasped workpiece in the detaching / attaching direction with respect to the sticking roller, and a workpiece movement for moving the workpiece in the direction of opening / separating from the mount in synchronization with the feeding of the tape. Means and means are adopted.

In the present invention, as a preferred mode of the above-mentioned pasting device, the work supply means is a belt conveyor for mounting and transporting the work, a pasting position set on the transport path, and a stop position for the work at a standby position before the first position. And a second movable stopper, and the work moving means is composed of a horizontal reciprocating moving table which works with the driving roller at the time of forward movement, and the separating / contacting means is the horizontal reciprocating movement. The apparatus according to claim (4) is composed of an elevating table attached to a table so as to be able to elevate and lower, and the chuck mechanism is integrally provided on the elevating table.

(Operation) In the sticking method and sticking apparatus of the present invention, since the double-sided adhesive tape layer of the double-sided adhesive tape with a mount is intermittently cut at a fixed position during each stop period of the tape, each adhesive tape layer is a unit. The length is determined by the tape speed and time during the running period, but the length of tape movement at the sticking position during each running period matches the length of each adhesive tape layer divided by the above cutting. Therefore, by setting the front end of each adhesive tape layer that was divided during the traveling stop period to be in the contact position with the work of the application roller, one adhesive tape layer is applied to the work during each traveling period. Be worn.

Then, since the works are individually fed to the sticking position one by one in each cycle of the intermittent running, there is no fear that one adhesive tape layer sticks to the target work and the next work. Further, at the attaching position, the work is held by the chuck and pressed against the attaching roller side to be pressed against the front end of each adhesive tape layer, and the work in this pressure contact state is synchronized with the tape during the running period of the tape and against the mount. The adhesive tape layers are naturally peeled from the mount and reliably transferred to the work surface because of the remarkable difference in adhesiveness between the mount surface and the work surface.

Moreover, in this transfer, since the work is separated from the sticking roller before the rear end of the adhesive tape layer contacts the work, the rear end is naturally pulled by the portion already stuck to the work. Since the front end portion of the next adhesive tape layer is spatially separated from the work surface while being peeled off from the mount, it is possible to surely avoid the situation where the next adhesive tape layer is continuously attached to the work surface. Therefore, even when the adhesive tape layer is attached only to a part of the work surface,
The next adhesive tape layer does not adhere to the surplus work surface.

Further, since the work held by the chuck at the sticking position is pressed to the sticking roller side and then separated and contacted from the sticking roller as described above, for example, the inner surface side of various flat cases or the inner surface side of the lid. Even if the workpiece has a shape in which the surface to which the adhesive tape layer is to be attached is recessed from the surroundings, the attaching method and the attaching apparatus of the present invention can be applied without any trouble.

In addition, the tape length from the cutting position of the adhesive tape layer to the applying position of the applying roller is divided so that the front end of each adhesive tape layer cut by cutting comes to the above-mentioned attaching position when the tape running is stopped. The length of the adhesive tape layer, that is, an integral multiple of the sticking length, is set, and in particular, in the sticking device of the present invention, the holding position of the disc blade can be displaced in the running direction of the tape. By adjusting the holding position according to the sticking length, the tape length can be easily set to an integral multiple of the sticking length, so that the sticking length can be either long or short depending on the size and type of the target work. It can be changed easily.

On the other hand, the cutting of the adhesive tape layer is performed in the form of push-cutting by the rolling of the disc blade under the pressure of the spring force, so that a constant cutting force is always applied to the contact portion of the tape with the blade edge, and the tape is cut over the entire length of the rolling locus. The cutting depth is constant according to the cutting force. In general, cutting the tape mount requires a much larger pressing force of the cutting edge than the adhesive tape layer.Therefore, by adjusting the spring force of the spring member, the pressing force of the disc blade is changed to the pressing force required for cutting the adhesive tape layer. If it is set to a range that is larger and smaller than the pressing force required to cut the mount, only the adhesive tape layer can be reliably cut leaving the mount by rolling the disc blade across the tape in the width direction. Therefore, the uncut portion of the adhesive tape layer and the cut or cut of the mount are completely avoided, and the tape can be stably run by pulling the mount.

On the other hand, in a general cutting method using an ordinary cutter, that is, a method in which a blade body that is fixedly held is moved in the tape width direction and pulled out, in order to keep the cutting depth constant, the moving direction of the blade body It must be set so that it is completely parallel to the tape width direction, and for this reason the dimensional accuracy and placement accuracy of the moving guide system of the blade must be rigorous in the μm unit, which increases the manufacturing cost of the device. It is necessary to use a tape that does not cause slight strain or thickness change in the adhesive tape layer and the backing sheet, and the adhesive component of the adhesive tape layer easily accumulates on the forward side of the blade edge due to the so-called scraping action, and the number of cuts As the adhesive strength increases, this adhesive component is deposited and accumulated on the cutting edge, leading to early deterioration of sharpness.
Furthermore, even if the blade body is configured to be pressed by the spring force in this pull-cutting method, the above-mentioned adhesion and accumulation of the adhesive component is unavoidable, and in addition, the cutting depth is caused by catching on the blade edge in the non-uniform portion of the adhesive tape layer. Fluctuates, which causes uncut portions of the adhesive tape layer and partial deep cuts of the mount.

Also, since the spring force of the spring member that presses the disc blade against the tape can be adjusted, the double-sided adhesive tape to be applied can be applied to the adhesive tape layer depending on the type and size of the work to be attached, the desired adhesive force, etc. Also, even when the material and thickness of the mount are changed, the pressing force of the disk blade can be easily set to the strength to reliably cut only the adhesive tape layer while leaving the mount by adjusting the spring force.

This supply device 5 is equipped with two sets of a storage cylinder 5a, a push-up tool 63, and a drive mechanism for the same on the base plate 65, and when one of the storage cylinders 5a becomes empty. By moving the base plate 5 on the guide rail 65a along the front-rear direction on the base 1 side, the other storage cylinder 5a is arranged immediately below the feeding claw 64 to continue the work supply.

To attach the double-sided adhesive tape to the work 17 such as a mirror for a makeup compact by the above-mentioned attaching device, confirm that the tape 16 is on the traveling path by the photoelectric sensor 66 shown in FIG. The reverse rotation motor 56 is driven to intermittently run the double-sided adhesive tape 16 with mount,
The work 17 is supplied onto the belt conveyor 2 at a rate of one sheet by the supply device 5 for each cycle of the traveling / stopping.

Here, when the tape 16 is not running, at the cutting position, the disc blade 25 of the cutting device 15 rolls in one direction across the tape 16 held by suction on the cutting table 12 and thereby the tape 16 Only the adhesive tape layer 16a is cut in the width direction while leaving the mount 16b. On the other hand, the horizontal reciprocating carriage 28, which was in the forward movement limit position, returns and stops at the chuck position as shown by the solid line in FIG. At this time, the work 17 to which the tape is to be stuck is stopped at the sticking position by the first stopper 42 projecting and waiting on the belt conveyor 2, and the next work in front of it is also stopped by the second stopper 43. It has been stopped. Then, the work 17 in the attaching position is chucked by being driven by the slide frames 36, 36 of the chucking device 4 toward both sides to be sandwiched between the two sandwiching pieces 37, 37 from both sides, and then the lifting table 32. 6th by rising
As illustrated in FIG. A, the tape 16 is pressed against the tape 16 on the sticking roller 10 while being separated from the belt conveyor 2 and being chucked. In addition,
The operation from the chuck to the pressing is performed within a short stop period in switching the rotation direction of the motor 56, that is, while the movable table 28 is stopped, and the first stopper 42 is retracted simultaneously with the pressing.

Next, during the running period of the tape 16, the moving table 28 is moved forward in synchronization with the feeding of the tape 16, and accordingly, one adhesive tape layer 16a divided into the required length by the cutting of the previous two cycles. However, when the tape 16 is pressed against the surface of the work 17 from the front end side at the position of the sticking roller 10, the tape 16 moves to the work 17 while being separated from the mount 16b as shown in FIG. 6B. Then, the lift table 32 is set so as to descend before the movable table 28 reaches the forward limit, and the adhesive tape layer 16a being transferred by this descending is attached to the work 17 before reaching the rear end portion. The pressure will be released, but the rear end is also shown in Fig. 6c.
As described above, by continuing the movement of the moving base 28, the moving base 28 is separated from the mount 16b and completely transferred onto the work 17. Therefore, it is possible to prevent the trouble that the front end portion of the next adhesive tape layer 16a continues to adhere onto the work 17 in advance. At the same time when the movable table 28 reaches the forward movement limit position, the drive roller 11 also stops, and at the same time, both slide frames 36, 36 of the chuck device 4 operate in the separating direction to release the chuck, and the adhesive tape layer 16a is adhered. The work 17 is carried out by the belt conveyor 2 at the end of the chute 2c.
Is conveyed to the subsequent step of attaching to the partner article. Also, on the belt conveyor 2, the second stopper 43
The first stopper 42 is projected at the same time when the work moves in and out, and the next workpiece 17 that has been waiting moves to the pasting position and is stopped. To stop.

After the chuck is released, the tape 16 is stopped, and the moving table 28 is returned to the chuck position during this period, and the cutting and the chucking and pressing of the work 17 are repeated again.

In the configuration of the above embodiment, the front and rear positions of the tape traveling table 3, the height of the sticking roller 10, and the left and right positions of the first stopper 42 can be adjusted, so that the thickness and width of the work,
It is possible to cope with changes in the width of the double-sided adhesive tape to be adhered, the starting position of the tape with respect to the work, the position in the width direction, and the like.

By the way, in the above-mentioned examples, an example of a flat plate-shaped work is shown, but the method and apparatus of the present invention can be applied to works of various shapes in which the sticking surface of the adhesive tape is flat,
For example, a work having a shape in which the surface on which the adhesive tape layer is to be stuck is recessed from the periphery, such as the inner surface side of various flat cases or the inner surface side of the lid, may be used.

Further, in the pasting device of the present invention, the structure of the tape running path, the reciprocating driving means of the disc blade, the chuck mechanism of the work,
Various design changes can be made to the detaching / attaching operation means of the work sticking roller, the work moving means synchronized with the tape running, and the like other than the embodiment.

(Effects peculiar to the invention) According to the pasting method and the pasting apparatus of the present invention, the double-sided adhesive tape is automatically and surely cut to a predetermined length with the double-sided adhesive tape being stuck to the backing sheet in an extremely simple cutting mechanism. In addition, after the cutting, the article can be automatically and continuously adhered to the surface of the work, which is one of the articles to be mutually adhered, in a state of being peeled from the mount, and the two articles are adhered to each other. The mass productivity of the product can be significantly improved and the manufacturing cost can be significantly reduced.

Moreover, in the above-mentioned pasting, it is possible to surely avoid the trouble that the one adhesive tape layer is pasted over the target work and the next work, or that the next adhesive tape layer is continuously attached to the work surface, It is not necessary to match the sticking length with the length of the work, and even if the adhesive tape layer is stuck on only a part of the work surface, there is no problem at all and a stable sticking state can be maintained at all times. It can be attached even when the surface to which the adhesive tape layer is to be attached is recessed from the surroundings, such as the inner surface side of the or the inner surface side of the lid, and there are few restrictions due to the shape and size of the work to be attached, It can be applied to a wide variety of workpieces.

Further, particularly in the pasting device of the present invention, since the holding position of the disc blade for cutting the adhesive tape layer can be displaced in the running direction of the tape, the size and type of the work targeting the pasting length of the adhesive tape layer. Even if the length is changed to either short or long according to the above, there is an advantage that it can be easily dealt with by the above displacement adjustment.

Further, in the pasting device of the present invention, the pressing force of the disc blade 25 against the tape can be adjusted by adjusting the spring force, and therefore, depending on the type and size of the work to be pasted, the target adhesive force, etc. Even when the adhesive tape is changed to one having a different material, thickness, etc. of the adhesive tape layer and the mount, it can be easily set so that only the adhesive tape layer can be reliably cut while leaving the mount.

In addition, the work supply means in the device of the present invention includes a belt conveyor for mounting and conveying the work, and first and second movable stoppers for stopping the work at the sticking position and the standby position before this which are set on the conveying path. According to the above configuration, there is an advantage that the work can be efficiently supplied and positioned at the pasting position.

Further, in the device of the present invention, the work moving means is composed of a horizontal reciprocating moving table which is interlocked with the driving roller at the time of forward movement,
If the separating / connecting means is composed of an elevating table attached to the horizontal reciprocating carriage so as to be able to ascend and descend, and the chuck mechanism is integrally provided on the elevating table, then a double-sided adhesive tape is provided via a sticking roller. A series of steps for transferring the sheet from the mount to the surface of the work and repetition of the steps can be efficiently performed with a simple device configuration.
