Description

[0001] TAPE APPLICATION DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape adhering apparatus for stripping a strip-shaped adhesive tape from a released paper and attaching an adhesive tape on a tape adhering surface formed on a work.

It is preferable to provide a black coating having no gloss on the interior side of the door sash of an automobile for the following reasons. That is, by suppressing the reflection of light on the interior side of the door sash when viewed from the outside of the vehicle, in particular, from the side of the vehicle body, a fresh appearance of the entire vehicle body can reliably be provided.

For this reason, spray painting of a delustering black paint on a door sash portion has been conventionally done. However, there are various problems such as the necessity of investment in auxiliary facilities for keeping the working environment well in the spray painting, and it takes time to dry the paint. As a solution to such a drawback, it has been proposed to attach a matte black adhesive tape having good weather resistance and abrasion resistance to the door cage in place, in Japanese Patent Application Laid-open No. 76-135015 or Japanese Patent Application Laid- 46780. In this case, as is well known, since most of the door chassis portion of the automobile is composed of the three-dimensional curved surface portion, the adhesive tape attaching device is inherently large in size. Further, when such an adhesive tape adhering apparatus is installed in an actual production line, the equipment cost for the production line becomes large. In addition, the ability to follow the design change of the door chassis portion is poor and the versatility is poor.

It can be considered that the work of attaching the adhesive tape is performed manually by an operator without using any device. However, in order to accurately perform an attaching operation at a speed suitable for an automobile production line, a high level of work skill is required.

Therefore, a tape adhering apparatus capable of easily and quickly attaching the adhesive tape without requiring a high degree of skill of the operator is proposed in Japanese Patent Laid-Open No. 93-338627. By using this tape attaching apparatus, it is possible to attach the adhesive tape to a predetermined position of the door chassis portion easily and quickly without requiring a high degree of skill of the operator.

Further, a device for automatically assembling a weather strip to a door cradle, for example, Japanese Patent Laid-Open Nos. 90-221582, 91-166068, and 93-65298 May also be applied.

In the conventional tape attaching apparatus disclosed in Japanese Patent Application Laid-Open No. 93-338627, there are a right-cut device and a left-cut device corresponding to a right door and a left door of an automobile. Therefore, in the case of a sedan passenger car, for example, four types of tape attaching devices are selectively used for the left front door, the left rear door, the right front door and the right rear door, respectively, .

In addition, when the shape of the door chassis portion varies depending on the vehicle type, a tape attaching device corresponding to the deformed shape must be prepared in all cases. That is, in the conventional tape attaching apparatus, flexibility corresponding to the change of the shape of the tape attaching surface is very insufficient.

On the other hand, when a weather strip mounting apparatus such as those disclosed in Japanese Patent Application Laid-Open Nos. 90-221582, 91-166068, and 93-65298 is applied to a tape attaching apparatus A space for installing a manipulator in addition to the maintenance and positioning device of the door panel is required. Therefore, if the manufacturing line of the automobile is not changed, such a demand can not be met.

It is therefore an object of the present invention to provide a tape attaching device which is highly adaptable to the shape of a tape attaching surface and which can accurately and easily attach the adhesive tape to predetermined positions of the left and right door caches without requiring a highly skilled worker.

According to the present invention, there is provided a tape attaching apparatus for attaching an adhesive tape on a tape attaching surface formed on a work, comprising: a device main body having a grip portion; A tape guiding portion having a pressing portion, a coupling means for slidably pressing the pressing portion on the tape attaching surface, and a protruding and retracting means capable of protruding and retracting the pressing portion along the pressing direction, A first engaging portion provided on the sliding block and having a first abutting portion detachably contacted with the work, and a second engaging portion provided on the sliding block so as to be opposed to the first engaging portion, And a second engaging portion having a second abutting portion which is provided on the workpiece and comes into contact with the work.

In the present invention, the leading end of the adhesive tape is attached to a predetermined position of the tape attaching surface of the work. Thereafter, the first contact portion and the second contact portion of the engaging means come into contact with the work so that the tape guide portion of the apparatus main body overlaps with the portion of the tape attaching surface to which the tip of the adhesive tape is attached. Thereby, the adhesive tape is pressed and held on the tape attaching surface by the pressing portion.

In this state, the apparatus main body moves along the tape attaching surface. An adhesive tape whose offset with respect to the tape attaching surface is limited by the tape guide portion is pressed on the tape attaching surface by the elastic deformation of the pressuring portion and is gradually attached to the tape attaching surface as the apparatus main body moves.

When the tape adhering apparatus is removed from the work, the slide block is operated to separate the first contact from the work. Then, the protruding means moves the pressing portion away from the tape attaching surface of the work.

In the present invention, the first contact portion may be a roller rotatably supported with respect to the sliding block. Similarly, the second contact portion may be a roller rotatably supported with respect to the apparatus main body. Thereby, the resistance when moving the tape adhering apparatus to the work can be reduced.

On the other hand, it is possible to arrange a plurality of second contact portions at predetermined intervals along the guiding direction of the adhesive tape by the tape guiding portion. Thereby, the tape attaching device can be engaged with the work without play.

It is also effective to form the surface of the pressing portion with an elastic body such as rubber. As a result, it is possible to uniformly adhere the adhesive tape on the tape attaching surface.

On the other hand, the sliding block can slide in the direction opposite to the first engaging portion and the second engaging portion. Thereby, when the sliding block slides so that the first engaging part moves away from the second engaging part, it becomes possible to attach and detach the tape attaching device to the work. In this case, it is preferable that a pressing means for pressing the first engaging portion toward the second engaging portion is provided between the apparatus main body and the sliding block. Thereby, the tape attaching device can be automatically positioned in a state of being coupled to the work.

The protruding means can be interlocked with the sliding block so as to operate in accordance with the sliding action of the sliding block. In this case, the protruding means includes a stepped shaft having a large diameter at its proximal end connected to the sliding block and a small diameter at its distal end connected to the large diameter via a tapered portion, a stepped shaft disposed coaxially with the stepped shaft, Wherein the tip end of the support pin is slidably engaged with the stepped shaft from the small diameter side and the pressurizing portion can have a stepped bore corresponding to the stepped shaft and rotatably supported on the stepped shaft .

That is, when the sliding block slides so as to move the first engaging part away from the second engaging part, the pressing part is separated from the tape attaching surface of the work by its own weight. Thereby, the large diameter bore of the pressing portion corresponding to the large diameter shaft of the stepped shaft is supported by the small diameter portion of the stepped shaft, and the small diameter bore portion of the pressing portion corresponding to the small diameter portion of the stepped shaft is supported by the support pin . On the other hand, when the sliding block slides so that the first engaging part moves toward the second engaging part, the pressing part protrudes against its own weight so as to come into press contact with the tape attaching surface of the work. Thereby, the large diameter bore portion of the pressing portion is supported by the large diameter portion of the stepped shaft, and the small diameter bore portion of the pressing portion is supported by the small diameter portion of the stepped shaft. In this case, the difference in diameter between the large diameter portion and the small diameter portion of the stepped shaft and the difference in diameter between the small diameter shaft and the support pin can be set substantially equal to each other. Thereby, the pressing portion can protrude and retreat in parallel with the axis of the stepped shaft.

According to the tape adhering apparatus of the present invention, the direction through which the adhesive tape passes does not have any directionality with respect to the tape guide portion of the apparatus main body. That is, along the longitudinal direction of the adhesive tape, the adhesive tape can pass through the tape guide in any direction. Therefore, the tape attaching apparatus of the present invention can be used for either the left work or the right work.

On the other hand, the first contact portion is displaced in the direction opposite to the second contact portion in accordance with the variation of the width or the shape of the work, in order to uniformly connect the apparatus main body to the work without clearance. As a result, even if it is not a skilled worker, the adhesive tape can be accurately attached on the tape attaching surface of the work. Further, the adaptability to the change of the shape of the work becomes better than the conventional one.

When the first and second contact portions are formed of rollers, the resistance upon movement of the tape adhering apparatus can be reduced. As a result, the tape attaching operation can be easily performed with a small operation force. Further, when the plurality of second contact portions are arranged along the guiding direction of the adhesive tape by the tape guiding portion, the tape attaching device can engage with the work without clearance. Therefore, the adhesive tape can be accurately attached on the tape adhering surface of the work.

When the surface of the pressing portion is formed of an elastic body such as rubber, the adhesive tape is uniformly attached to the tape attaching surface while preventing the incorporation of bubbles. In addition, when the protruding means is interlocked with the operation of the slide block, the tape attaching device can be easily attached to and detached from the work.

The invention will be more fully understood from the following detailed description of the preferred embodiments of the invention and the accompanying drawings, which are not intended to limit the invention, but merely for explanation and understanding.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without these specific details. Known structures are not shown in the detailed description, as they make the present invention unnecessarily obscure.

An end block 12 which is in contact with one side end face of the adhesive tape 11 and a holder block 13 which is in contact with the other side end face of the adhesive tape 11 are provided with a pair of tape guide portions (Not shown). That is, the pair of tape guides 14 has a length corresponding to the width of the adhesive tape 11 (the length in the vertical direction in Fig. 3). The surfaces of these tape guiding portions 14 are covered with a member 15 having a low coefficient of friction such as a high density polyethylene sheet. On the other hand, as the pressing portion of the present invention, the pressing drum 16 is disposed between the pair of tape guiding portions 14. The supporting structure of the pressure drum 16 will be described later.

A pair of locating rollers 18, which can be engaged with the outside of the front door cage 17, are rotatably mounted on the end block 12. A part of the outer peripheral portion of the positioning roller 18 protrudes just above the front end side (the lower side in Fig. 3) of the tape guide portion 14. [ The pair of positioning rollers 18 serve as a second engagement portion having the second contact portion of the present invention. The positioning roller 18 can be replaced with a roller having an optimal dimension and shape in accordance with the dimension and shape of the front door cage portion 17 in the width direction.

On the holder block 13, a pair of guide wall portions 19 are vertically installed parallel to each other. Between these guide wall portions 19, a sliding block 20 is slidably received so as to slide in the direction of the direction of the positioning roller 18. Further, the guide bar holder 21 is vertically extended at an end portion of the holder block 13 opposite to the tape guide portion 14. The guide bar holder 21 is opposed to the sliding block 20. [

The apparatus main body 22 in the present embodiment includes the end block 12, the holder block 13, the guide wall 19, the guide bar holder 21, and the gripping member 23 It should be noted.

And the holding plate 24 is fixed to the upper end of the guide wall portion 19 through the respective fixing screws 25. These retaining plates 24 serve to prevent the sliding block 20 from falling upward from the guide wall 19. On the other hand, the stopper 27 protrudes downward from the guide rod holder 21 side of the slide block 20. [ The stop 27 engages with a stepped portion 26 formed at the center of the holder block 13. Thus, the slidable block 20 is successfully prevented from falling to the end block 12 side. The proximal ends of the pair of guide rods 29 are fixed in the guide rod holder 21 by the fixing screws 30. [ The tip ends of the guide rods 29 are slidably engaged with the pair of guide holes 28. The pair of guide holes 28 are formed in the sliding block 20 parallel to each other along the direction in which the end block 12 and the holder block 13 are opposed to each other. And a compression coil spring 31 for pressing the sliding block 20 toward the end block 12 is wound on these guide rods 29. [ The compression coil spring 31 is disposed between the sliding block 20 and the guide bar holder 21. [

Thus, the sliding block 20 is urged toward the end block 12 by the compression coil spring 31. That is, the slide block 20 can move toward the guide bar holder 21 against the spring force of the compression coil spring 31. [

The side surface of the slide block 20 opposite to the end block 12 protrudes just above the pressure drum 16. [ A holding roller 32 acting as a first contact portion of the present invention is provided so as to protrude on this side of the slide block 20 opposite to the end block 12. [ The holding roller 32 can engage with the front door claw 17 together with the pair of positioning rollers 18. [ The apparatus main body 22 is engaged with the front door claw 17 by the holding roller 32 and the positioning roller 18. At this time, the pressing drum 16 is pressed onto the flat tape attaching surface 33 of the front door claw 17. Further, the grip portion 34 protrudes from the upper end of the sliding block 20. The handle portion 34 is used to retract the sliding block 20 toward the guide rod holder 21 against the spring force of the compression coil spring 31. [

A guide groove 35 extending along the direction opposite to the end block 12 and the holder block 13 is formed at the center of the rear surface of the slide block 20. [ A stepped shaft (38) is slidably disposed in the guide groove (35). The stepped shaft 38 is fixed to the slide block 20 on the side opposite to the guide rod holder 21 with the fixing screw 37 through the connecting plate 36. [ The stepped shaft 38 has a large diameter portion 39 having a proximal end portion fixed to the connecting plate 36 by a fixing screw 37, a small diameter portion 40 located at the distal end thereof, a large diameter portion 39, And a tapered portion 41 connecting the small-diameter portion 40 with each other. The axis of the stepped shaft is set parallel to the direction in which the end block 12 and the holder block 13 are opposed to each other.

A fixing groove 42 extending along the direction opposite to the end block 12 and the holder block 13 is formed on the center of the rear surface of the end block 12. [ The proximal end of the support pin 45 is fixed in the fixing groove 42. The support pin 45 is held on the back surface of the end block 12 via the fixing plate 43 with the fixing screw 44. The support pin 45 is set coaxially with the stepped shaft 38. The tip of the support pin (45) is slidably engaged with the pin engagement hole (46) formed from the tip end surface of the stepped shaft (38). That is, the tip of the stepped shaft 38 is supported by the support pin 45.

The pressure drum 16 has a large diameter bore portion 47 facing the stepped shaft 38 and a small diameter bore portion 48 and a taper bore portion 49. Thus, the pressure drum 16 is rotatably supported by the stepped shaft 38. [ The engagement length (the contact length in the lateral direction in Fig. 4) between the large-diameter bore portion 47 of the pressure drum 16 and the large-diameter portion 39 of the stepped shaft 38, The coupling lengths between the diameter bore 48 and the small diameter shaft 40 of the stepped shaft 38 are set to be equal to each other. 4 in which the step 26 of the holder block 13 contacts the stop 27 and the slide block 20 is retracted toward the guide rod holder 21 by a predetermined distance, The engaging position moves so that the small diameter bore portion 48 of the pressing drum 16 comes into contact with the supporting pin 45 by the own weight of the pressing drum. Diameter bore 47 is brought into contact with the small diameter portion 40 of the stepped shaft 38. At this time, Thus, as shown in Fig. 6, the pressing drum 16 is positioned floating with respect to the support pin 45 and the stepped shaft 38. As shown in Fig.

The coupling length between the large diameter bore 47 of the pressing drum 16 and the large diameter shaft 39 of the stepped shaft 38 in the state shown in Fig. It should be set appropriately according to the width of the sealing portion 17. Similarly, the coupling length between the small diameter bore portion 48 of the pressing drum 16 and the small diameter portion 40 of the stepped shaft 38 is determined by the length of the front door claw portion 17 It should be set appropriately according to the width. The surface of the pressure drum 16 should be covered with an elastic body 50 such as rubber such as foamed polyurethane, hard rubber or the like which can be deformed in the radial direction.

The difference in diameter between the large diameter portion 39 and the small diameter portion 40 of the stepped shaft 38 in this embodiment is the same as the difference between the diameter of the small diameter portion 40 and the diameter between the support pins 45 Is set. Thereby, when the sliding block 20 is retracted from the position shown in Fig. 4 to the position shown in Fig. 6, the pressing drum 16 is moved toward the gripping member 23 with its axis kept parallel .

The proximal end of the holding member 23 is fixed to the center of the holder block 13 by a fixing screw 52 through a pair of brackets 51. [ The gripping member 23 extends so as to protrude just below the pressing drum 16 along the direction opposite to the end block 12 and the holder block 13. [ The gripping member 23 forms a gap 53 with the pressing drum 16.

At the time of adhering operation, the leading end of the adhesive tape 11 is peeled off from the release paper 54 first. Thereafter, the tip of the adhesive tape 11 is attached to a predetermined position (generally, the attachment start position) of the flat tape attaching surface 33. Thereafter, the sliding block 20 is moved away from the end block 12 by using the grip portion 34. [ The apparatus main body 22 is placed in a state in which the holder block 13 of the apparatus main body 22 is positioned so as to overlap with the portion of the tape attaching surface 33 to which the tip of the adhesive tape 11 is attached, And is pressed onto the cyan portion 17. The positioning roller 18 and the holding roller 32 are engaged with the front door claw portion 17 by the spring force of the compression coil spring 31 by releasing the finger from the grip portion 34. [

As a result, the pressing drum 16 is pushed up toward the tape attaching surface 33. By further moving upward, the pressing drum 16 is brought into contact with the tape attaching surface, and elastic deformation is caused such that the elastic body 50 such as rubber on the surface thereof is pressed. Therefore, the adhesive tape 11 is kept pressed on the tape attaching surface 33. [ Further, when the sliding block 20 is pressed away from the end block 12, the distance between the pressing drum 16 and the roller is increased. Therefore, detachment and attachment of the tape attaching device to the front door claw 17 can be facilitated.

From this state, while peeling off the release paper 54, the apparatus main body 22 is moved along the tape attaching surface 33 toward the left side in Fig. The tape guiding portion 14 limits the offset of the adhesive tape 11 in the lateral direction with respect to the tape attaching surface 33. [ The adhesive tape 11 is pressed onto the tape attaching surface 33 by elastic deformation of the pressing drum 16. [ Therefore, the adhesive tape 11 can be stuck on the tape attaching surface 33 while maintaining the above-described state.

In this case, since the sliding block 20 is constantly urged toward the pair of positioning rollers 18 by the spring force of the compression coil spring 31, The front door sash 17 is displaced with respect to the width of the front door cushion 17 or the shape of the front door cushion 17. [ As a result, the apparatus main body 22 can be engaged with the front door claw 17 without clearance to the positioning roller 18. [ On the other hand, since the surface of the tape guiding portion 14 is covered with the member 15 of low coefficient of friction and the pressing drum 16 is rotatably supported on the stepped shaft 38, The frictional resistance when moving the apparatus main body 22 can be reduced. As a result, the tape attaching operation can be easily performed.

Thus, the adhesive tape 11 is attached to the tape attaching surface 33 of the front door claw 17. After completing the tape attaching operation, both ends in the width direction of the adhesive tape 11 are attached on the remaining portion of the front door claw 17 using a squeezing roller (not shown). Since the adhesive tape 11 is already positioned with respect to the front door claw 17, the attachment operation in this state can be carried out without any difficulty.

It is also possible to position the adhesive tape 11 and the release paper 54 in the forward direction as shown in Fig. In this case, the adhesive tape 11 and the release paper 54 pass through the gap 53 between the gripping member 23 and the tape guide 14. Then, the adhesive tape (11) is bent over the tape guide portion (14). Thereby, only the release paper 54 can be positioned in front of the moving direction of the apparatus main body 22. [ As a result, it is possible to improve the efficiency of the tape attaching operation.

On the other hand, the front door claw portions 17 are generally symmetrical on the left and right sides of the vehicle body. Therefore, the direction of passage of the adhesive tape 11 with respect to the tape guide portion 14 is reversed from the state shown in Figs. 5 and 7 in accordance with the left and right uses, and the apparatus main body 22 is moved in the forward door claw 17 In the opposite direction. Therefore, this embodiment of the tape-attaching apparatus can be applied to the left and right front door caches without any modification.

Further, when the width and shape of the front door claw portion 17 are significantly different depending on the vehicle type, by replacing the positioning roller 18 and the holding roller 32 with rollers having different sizes and / or shapes, This embodiment of the attachment device can be matched or adjusted.

While the present invention has been shown and described with respect to the preferred embodiments, those skilled in the art will be able to make modifications, omissions, and additions thereto without departing from the spirit and scope of the invention. It is therefore to be understood that the invention is not to be limited to the specific embodiments disclosed, but on the contrary, is intended to cover all possible embodiments which fall within the scope of protection and equivalence to the features disclosed in the appended claims. For example, although the present embodiment uses the cylindrical pressing drum 16 as the pressing portion, a flat pressing member can also be applied. In this embodiment, the stepped shaft 38 and the corresponding stepped bore are used as the protruding means for the pressing drum 16. However, any other structure capable of projecting and retracting the pressure drum 16 in conjunction with the sliding operation of the sliding block can be used.

According to the tape adhering apparatus of the present invention, the direction through which the adhesive tape passes does not have any directionality with respect to the tape guide portion of the apparatus main body. That is, along the longitudinal direction of the adhesive tape, the adhesive tape can pass through the tape guide in any direction. Therefore, the tape attaching apparatus of the present invention can be used for either the left work or the right work.

On the other hand, the first contact portion is displaced in the direction opposite to the second contact portion in accordance with the variation of the width or the shape of the work, in order to uniformly connect the apparatus main body to the work without clearance. As a result, even if it is not a skilled worker, the adhesive tape can be accurately attached on the tape attaching surface of the work. Further, the adaptability corresponding to the shape of the work is superior to the conventional one.

When the first and second contact portions are formed of rollers, the resistance upon movement of the tape adhering apparatus can be reduced. As a result, the tape attaching operation can be easily performed with a small operation force. Further, when the plurality of second contact portions are arranged along the guiding direction of the adhesive tape by the tape guiding portion, the tape attaching device can engage with the work without clearance. Therefore, the adhesive tape can be accurately attached on the tape adhering surface of the work.
