The engaging means includes a first contact element such as roller 32 attached to a sliding block 20 that is movably mounted in a holding block 13, and a second contact element such as rollers 18 mounted on the main body. The first and second contact elements may be biassed towards opposing sides of the work surface by compression springs 31. The pressing portion may be an elastically deformable roller 16 mounted on a stepped shaft (38, figs 4 and 6), which is connected to the sliding block. When the sliding block moves the first contact element into contact with the work surface, the stepped shaft also moves and forces the deformable roller into a pressing position.
Description
1 TAPE APPLICATION DEVICE 2320485 The present invention relates to a tape
application device peeling a strip form adhesive tape off a released paper and applying the adhesive tape on a tape applying surface formed on a work.
It is desirable to provide delustering black coating on the interior side of a door sash of an automotive vehicle, in view of the following reason.
Namely, as viewed from the outside of the vehicle, particularly from the side of a vehicle body, clear external appearance of a overall vehicle body can be certainly provided by restricting reflection of a light at the interior side of the door sash.
For this purpose, it has been conventionally performed to perform spray painting of delustering black paint on the door sash portion. However, spray painting encounters various problems as requiring investment for additional facility for maintaining work environment good enough, taking a long period for drying paint, and so forth. As a solution for such drawback, Japanese Patent Application Laying-open No. 135015/1976 or Japanese Patent Application Laying-open No. 46780/1987 proposes application of delustering black adhesive tape having high weather resistance and high wear resistance on a door sash portion, in place. In 2 such case, as is well known, since the most part of the door sash portion of an automotive vehicle is consisted of three-dimensional curved portion, the above-mentioned adhesive tape application apparatus inherently becomes large scale. Also, when such adhesive tape application apparatus is installed in a practical production line, an investment for production line becomes huge. In addition, it has poor flexibility in adapting to modification of design of the door sash portion, and has poor general-purpose properties.
It can be considered that the operation for application of the adhesive tape is performed manually by the worker without using any device.
However, in order to accurately perform applying operation at a speed adapted to the production line of the automotive vehicle, quite high skill is required. Thus, there has been proposed in Japanese Patent 20 Application Laying-open No. 338627/1993, a tape application device which can easily and quickly perform application of the adhesive tape without requiring high skill of the worker. By employing the tape application device, the adhesive tape can be accurately applied at a predetermined position of the door sash portion easily and quickly without requiring high skill of the worker.
1:
3 In addition, a device for automatically assembling a weatherstrip to a door sash portion, such as those disclosed in Japanese Patent Application Laying-open No. 221582/1990, Japanese Patent Application Laying-open No. 166068/1991 or Japanese Patent Application Publication No.
65298/1993, may also be applicable.
In the conventional tape application device, disclosed in Japanese Patent Application Laying-open No. 338627/1993, there are right-cut device and left-cut device adapting to a right side door and a left side door of the automotive vehicle.
Therefore, in case of sedan type passenger vehicle, for example, four kinds of tape application device respectively for a left front door, a left rear door, a right front door and a right rear door have to be used selectively to make tape applying operation complicate and troublesome.
Also, when shape, such as width of the door sash portion and so forth in one model of the vehicle is modified, the tape application device adapted to the modified shape has to be prepared at every occasion. Namely, the conventional tape application device has quite poor flexibility in adapting to modification of the shape of the tape applying surface.
On the other hand, when the weatherstrip installation device, such as those disclosed in 1 Japanese Patent Application Laying-open No. 221582/1990, Japanese Patent Application Laying-open No. 166068/1991 or Japanese Patent Application Publication No. 65298/1993 are converted over the tape application device, a space for setting up a manipulator in addition to a holding and positioning device of a door panel. Therefore, it becomes not possible to adapt to such requirement unless a manufacturing line of the automotive vehicle is 10 modified.
Therefore, it is an object of the present invention to provide a tape application device which has high flexibility in adapting to the shape of tape applying surfaces and thus permits accurate application of an adhesive tape at predetermined positions on left and right door sash portions, easily and quicklSr without requiring highly skilled worker. According to the invention, a tape application device for applying an adhesive tape on a tape applying surface formed on a work, comprising: a main body having a gripping portion; a tape guide portion provided in the main body and having a pressing portion for pressing the adhesive tape onto the tape applying surface; i engaging means for slidably pressing the pressing portion onto the tape applying surface; and projecting and retracting means for projecting and retracting the pressing portion along pressing direction; the engaging means including first engaging portion having a sliding block held slidably with respect to a holder block provided in the main body, and a first contact portion provided in the sliding block and releasably contacting with the work; and second engaging portion provided on the main body in opposition to the first engaging portion across the tape guide portion and having a second engaging portion with a second contact portion contacting with the work.
In the present invention, the distal end of the adhesive tape is affixed to the predetermined position of the tape applying surface of the work.
Next, the first contact portion and the second contact portion of the engaging means contact with the work so that the tape guide portion of the main body may overlap with the portion of the tape applying surface where the distal end of the adhesive tape is affixed. Hereby, the adhesive tape is held pressed onto the tape applying surface by the pressing portion.
6 - At this condition, the main body moves along the tape applying surface. The adhesive tape restricted offset with respect to the tape applying surface by the tape guide portion, is pressed onto the tape applying surface with elastic deformation of the pressing portion, and progressively affixed to the tape applying surface according to movement of the main body.
In the case where the tape application device is removed from the work, the slide block is operated to release the first contact portion from the work. Then, the projecting and retracting means moves the pressing portion away from the tape applying surface of the work.
In the present invention, the first contact portion may be a roller rotatably supported with respect to the slide block. Similarly, the second contact portion may be a roller rotatably supported with respect to the main body. Hereby, resistance uponmovement of the tape application device with respect to the work can be reduced.
on the other hand, it is possible to arrange a plurality of second contact portions with a given interval along guiding direction of the adhesive tape by the tape guide portion. Hereby, the tape application device can engage with the work without play.
7 Furthermore, it is effective to form the surface of the pressing portion with a rubber-like elastic body. Hereby, it is possible to apply evenly the adhesive tape on the tape applying surface.
On the other hand, the slide block may be slidable in opposing direction of the first engaging portion and the second engaging portion. Hereby, when the sliding block slides so that the first engaging portion moves away from the second engaging portion, it becomes possible to attach and detach the tape application device to and from the work.
In this case, it is preferred that biasing means for biasing the first engaging portion toward the second engaging portion is provided between the main body and the slide block. Hereby, the tape application device can be automatically placed in engaged condition to the work.
The projecting and retracting means may be associated with the sliding block for operation according to sliding operation of the latter. In this case, the projecting and retracting means may include a stepped shaft having a larger diameter portion at a proximal end portion connected to the slide block and a smaller diameter portion at a distal end portion connected to the larger diameter portion via a tapered position, and a holding pin arranged coaxially with the stepped shaft and 8 supported on the main body at a proximal end portion thereof, the distal end of the support pin is slidably engaged with the stepped shaft from the smaller diameter portion side, and the pressing portion may have a stepped bore corresponding to the stepped shaft and is rotatably supported on the stepped shaft.
Namely, when the slide block slides to shift the first engaging portion away from the second engaging portion, the pressing portion moves way from the tape applying surface of the work by own weight. Hereby, the larger diameter bore portion of the pressing portion corresponding to the large diameter portion of the stepped shaft is supported by the smaller diameter portion of the stepped shaft, and the smaller diameter bore portion of the pressing portion corresponding to the smaller diameter portion of the stepped shaft is supported by the support pin. Conversely, when the slide block slides so that the first engaging portion moves toward the second engaging portion, the pressing portion projects for pressure contact with the tape adhesive surface of the work against own weight. Hereby, the larger diameter bore portion of the pressing portion is supported by the larger diameter portion of the stepped shaft and the smaller diameter bore portion of the pressing portion is 1 9 supported by the smaller diameter portion of the stepped shaft. In this case, a difference of diameters between the larger diameter portion and the smaller diameter portion of the stepped shaft and a difference of diameters between the smaller diameter portion of the stepped shaft and the diameter of support pin may be set substantially equal to each other. Hereby, the pressing portion may project and retract in parallel to the axis of the stepped shaft.
According to the tape application device of the present invention, the direction to pass the adhesive tape has no directionality relative to the tape guide portion of the main body. Namely, along the longitudinal direction of the adhesive tape, the adhesive tape can pass the tape guide portion in either direction. Therefore, the device can be used in either of left-cut and right-cut works.
On the other hand, the first contact portion is displaced in opposing direction to the second contact portion following variation of the width of the work and variation of configuration to constantly engage the main body with the work without play. As a result, without requiring skilled worker, the adhesive tape can accurately affix on the tape applying surface of the work. In t 1 addition, adapting ability to variation of configuration of the work becomes superior that the conventional one.
In the case where the first and second contact portions are formed by rollers, resistance upon movement of the tape application device can be reduced. As a result, tape application work can be done easily with small operation force. Furthermore, in the case where a plurality of second contact portions are arranged along guiding direction of the adhesive tape by the tape guiding portion, the tape application device can engage with the work without any play. Therefore, the adhesive tape can be affixed on the tape applying surface of the work.
In the case where the surface of the pressing portion is formed with the rubber-like elastic body, the adhesive tape is applied to the tape applying surface with irregularity preventing admixing of the air bubble. In addition, in the case where the projecting and retracting means is associated with operation of the slide block, the tape application device can be easily attached and detached to and from the work.
The present invention will be understood more fully from the detailed description given herebelow
Z4 ' c and from the accompanying drawings of the preferred embodiment of the invention, which, however, should not be taken to be limitative to the present invention, but are for explanation n and understanding only.
In the drawings:
Fig. 1 is a perspective view showing an external appearance of one embodiment of a tape application device according to the present invention as applied for a front door inner sash portion of a passenger vehicle; Fig. 2 is an exploded perspective view of the embodiment shown in Fig. 1; Fig. 3 is a plan view of the embodiment shown in Fig. 1; Fig. 4 is a section taken along line IV IV of Fig. 3; Fig. 5 is a section taken along line V V of Fig. 3; Fig. 6 is a section corresponding to Fig. 4 but showing a condition where a slide block is operated; Fig. 7 is a front elevation of the embodiment of the tape application device shown in Fig. 1, in which the tape application device is coupled with the front door sash portion; and Fig. 8 is a left side elevation of the embodiment of the tape application device shown in 1 c 12 Fig. 1, in which the tape application device is coupled with the front door sash portion.
The present invention will be discussed hereinafter in detail in terms of the preferred embodiment of a tape application device as applied for a front door sash portion of a passenger vehicle, with reference to Fig. 1 showing an external appearance, showing in exploded condition, Fig. 3 showing a plan view, Figs. 4 and 5 respectively showing sections taken along line IV IV and line V - V, Fig. 6 showing a front elevation in a condition connected to a front door sash portion, and Fig. 7 is a left side elevation thereof. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be obvious, however, to those skilled in the art that the present invention may be practiced without these specific details. In other instance, well-known structures are not shown in detail in order to unnecessary obscure the present invention.
Namely, the end block 12 contacting with one side end face of the adhesive tape 11 and the holder block 13 contacting with the other side end face of the adhesive tape 11 are integrally coupled via a pair of tape guide portions 14 extending in parallel 13 - to each other. Namely, a pair of tape guide portions 14 have lengths corresponding to width of (length in vertical direction in Fig. 3) of the adhesive tape 11. The surfaces of these tape guide portions 14 are coated with members 15 having low friction coefficient, such as high density polyethylene sheet. On the other hand, between a pair of the tape guide portions 14, a pressure drum 16 is arranged as pressing portion of the present invention. A support structure of the pressure drum 16 will be explained later.
on the end block 12, a pair of positioning rollers 18 engageable with the outer side of the front door sash portion 17, are mounted rotatably.
Part of the outer peripheral portions of the positioning rollers 18 are projected right above the front end side (lower side in Fig. 3) of the tape guide portion 14. A pair of positioning rollers 18 serve as second engaging portion having the second contact portion of the present invention. The positioning rollers 18 can be exchanged to those of optimal dimension and configuration depending upon a dimension in the width direction and configuration of the front door sash portion 17.
On the holder block 13 set forth above, a pair of guide wall portions 19 are provided vertically in parallel relationship to each other. Between these 14 K 1 1 g'de wall portions 19, the slide block 20 is ul slidably received for sliding in the opposing direction to the positioning rollers 18. Also, at the end portion of the holder block 13 at the opposite side of the tape guide portions 14, the guide bar holder 21 is provided to extend vertically. The guide bar holder 21 opposes to the slide block 20.
It should be noted that the main body 22 in the shown embodiment is constructed with the foregoing end block 12, the holder block 13, the guide wall portion 19, the guide bar holder 21 and also a gripping member 23 and the like.
At the upper end of the guide wall portion 19, the holding plates 24 are fixed via respective fastening screws 25. These holding plates 24 serves for preventing the slide block 20 from loosing off the guide wall portion 19 in upward direction. on the other hand, at the guide bar holder 21 side of the slide block 20, a stopper portion 27 is projected downwardly. The stopper portion 27 engages with a stepped portion 26 formed at the center portion of the holder block 13. Thus, loosing off of the slide block 20 to the end block 12 side is successfully prevented. Also, in the guide bar holder 21, proximal end portions of a pair of guide bars 29 are fixed by fastening screws 30.
- 15 z -) The distal ends of these guide bars 29 are slidably engaged with a pair of guide holes 28. A pair of guide holes 28 are formed in the slide block 20 along opposing direction to the end block 12 and the holder block 13 in parallel relationship to each other. On these guide bars 29, compression coil springs 31 for biasing the slide block 20 toward the end block 12 are wound around. The compression coil spring 31 is arranged between the slide block 20 and the guide bar holder 21.
Accordingly, the slide block 20 is biased toward the end block 12 by the compression coil springs 31. Namely, the slide block 20 can move toward the guide bar holder 21 against the spring force of the compression coil spring 31.
The side of the slide block 20 opposing the end block 12 is projected right above the pressure drum 16. on this side of the slide block 20 opposing to the end block 12, a holing roller 32 serving as a first contact portion of the present invention is projectingly provided. The holding roller 32 is engageable with the front door sash portion 17 together with a pair of positioning roller 18. With this holding roller 32 and the positioning rollers 18, the main body 22 is engaged with the front door sash portion 17. Then, the pressure drum 16 is pushed upon a flat tape applying surface 33 of the 1 W-) front door sash portion 17. Also, on the upper end of the slide block 20, a finger grip portion 34 is projected. The finger grip portion 34 is useful for retracting the slide block 20 toward the guide bar holder 21 against the spring force of the compression coil springs 31.
At the center portion of back side of the slide block 20, a guide groove 35 extending along the opposing direction of the end block 12 and the holder 13, is formed. In the guide groove 35, a stepped shaft 38 is disposed in sliceable fashion. The stepped shaft 38 is fixed to the slide block 20 at the side opposing to the guide bar holder 21 by means of fastening screws 37 via a connecting plate 36. The stepped shaft 38 has a larger diameter portion 39 having the proximal end portion fixed to the connecting plate 36 by the screws 37, a smaller diameter portion 40 located at the distal end portion thereof, and a tapered portion 41 connecting these larger diameter portion 39 and the smaller diameter portion 40. The axis of the stepped shaft is set in parallel to the opposing direction of the end block 12 and the holder block 13.
On the center portion of the back side of the end block 12, a stationary groove 42 extending in opposing direction of the end holder 12 and the holder block 13 is formed. In the stationary block - 17 42, the proximal end portion of a supporting pin 45 is secured. The supporting pin 45 is held at the back side of the end block 12 by means of fastening screws 44 via a fastening plate 43. The support pin 5 45 is set coaxially with the stepped shaft 38. The distal end of the supporting pin 45 is slidably engaged with a pin receptacle hole 46 formed from the distal end face of the stepped shaft 38. Namely, the distal end of the stepped shaft 38 is supported by means of the supporting pin 45.
The pressure drum 16 has a larger diameter bore portion 47 opposing to the stepped shaft 38, a smaller diameter bore 48 and a tapered bore portion 49. Then, the pressure drum 16 is rotatably supported on the stepped shaft 38. An engaging length (contact length in the lateral direction in Fig. 4) between the larger diameter bore portion 47 of the pressure drum 16 and the larger diameter portion 39 of the stepped shaft 38 and engagement length between the smaller diameter bore portion 48 of the pressure drum 16 and the smaller diameter portion 40 of the stepped shaft 38 are set to be equal to each other. Accordingly, when the slide block 20 is retracted toward the guide bar holder 21 for a predetermined distance from the condition shown in Fig. 4 where the stepped portion 26 of the holder block 13 is in contact with the stopper i portion 27, these engaging positions are shifted so that the smaller bore portion 48 of the pressure drum 16 comes into contact with the supporting pin by the own weight of the pressure drum 16. Then, the larger diameter bore 47 comes into contact with the smaller diameter portion 40 of the stepped shaft 38. Thus, as shown in Fig. 6, the pressure drum 16 is placed in floating condition relative to the supporting pin 45 and the stepped shaft 38.
It should be noted that the engaging length of the larger diameter bore portion 47 of the pressure drum 16 and the larger diameter portion 39 of the stepped shaft 38 in the condition shown in Fig. 4 has to be set appropriately depending upon the width of the front door sash portion 17, on which the shown tape application device is to be used. Similarly, the engaging length between the smaller diameter bore portion 48 of the pressure drum 16 and the smaller diameter portion 40 of the stepped shaft 38 has to be set appropriately depending upon the width of the front door sash portion 17, on which the shown tape application device is to be used. Also, the surface of the pressure drum 16 has to be covered with a rubber-like elastic body 50, such as a foamed polyurethane, hard rubber and the like, which can be deformed in radial direction.
c 1 19 In the shown embodiment, a difference of the diameters of the larger diameter portion 39 and the smaller diameter portion 40 of the stepped shaft 38 is set to be equal to a difference of the diameter of the smaller diameter portion 40 and the diameter of the supporting pin 45. Hereby, when the slide block 20 is retracted from the position shown in Fig. 4 to the retracted position shown in Fig. 6, the pressure drum 16 can be shifted toward the gripping member 23 with maintaining parallelism of the axis thereof.
At the center portion of the holder block 13, the proximal end portion of the gripping member 23 is fixed by means of fastening screws 52 via a pair of brackets 51. The gripping member 23 extends along the opposing direction of the end block 12 and the holder block 13 to project right below the pressure drum 16. Then, the gripping member 23 defines a clearance 53 together with the pressure drum 16.
Upon applying operation, at first, the distal end portion of the adhesive tape 11 is peeled from the released paper 54. Then, the distal end of the adhesive tape 11 is applied to the predetermined position (generally, application start position) of the flat tape applying surface). Next, utilizing the finger grip portion 34, the slide block 20 is moved away from the end block 12. With maintaining this condition, the main body 22 is pressed onto the front door sash portion 17 so that the holder block 13 of the main body 22 is placed to overlap with the 5 portion of the tape applying surface 33 where the distal end portion of the adhesive tape 11 is affixed. Then, by releasing the finger from the finger grip portion 34, the positioning roller 18 and the holding roller 32 are engaged to the front door sash portion 17 by the spring force of the compression coil spring 31.
Hereby, the pressure drum 16 is pushed up toward the tape applying surface 33. By further upward movement, the pressure drum 16 contacts with the tape applying surface and causes elastic deformation in such a manner than the rubber-like elastic body 50 on the surface thereof is pressed. Thus, the adhesive tape 11 is in pressed condition onto the tape applying surface 33. Also, when the slide block 20 is forced away from the end block 12, the distance between the pressure drum 16 and the roller is increased. Therefore, attaching and detaching the tape application device to and from the front door sash portion ly can be facilitated.
From this condition, the main body 22 is moved toward left in Fig. 7 along the tape applying surface, with peeling off the released paper. The 11 4) 21 tape guide portion 14 restricts offset of the adhesive tape 11 in the lateral direction relative to the tape applying surface 33. Then, the adhesive tape 11 is pressed onto the tape applying surface 33 with elastic deformation of the pressure drum 16. Thus, the adhesive tape 11 can be affixed onto the tape applying surface 33 with maintaining the condition set forth above.
In this case, since the slide block 20 is constantly biased toward a pair of positioning rollers 18 by the spring force of the compression coil spring 31, the slide block 20 is displaced relative to the positioning roller 18 following to variation of the width or variation of the contour of the front door sash portion 17. As a result, the main body 22 can be engaged to the front door sash portion 17 without play with respect to the positioning rollers 18. On the other hand, since the surface of the tape guide portion 14 is covered with the member 15 having low friction coefficient and the pressure drum 16 is rotatably supported on the stepped shaft 38, frictional resistance upon moving the main body 22 along the tape applying surface 33 can be small. As a result, tape applying operation can be done easily.
Thus, application of the adhesive tape 11 onto the tape applying surface 33 of the front door sash 22 - f portion 17 is performed. After completion of the tape applying operation, by means of not shown squeezing roller, the both edge portions of the adhesive tape 11 in the width direction are affixed onto the remaining portion of the front door sash portion 17. The applying operation in this condition can be done without any difficulty since the adhesive tape 11 has already been positioned relative to the front door sash portion 17.
It is possible to place the adhesive tape 11 and the released paper 54 at the front side of the traveling direction as shown in Fig. 5. In this case, the adhesive tape 11 and the released paper 54 are passed through a clearance 53 between the gripping portion 23 and the tape guide portion 14. Then, the adhesive tape 11 is turned over the tape guide portion 14. Hereby, only the released paper 54 can be placed at the front side of the traveling direction of the main body. As a result, it is possible to enhance the efficiency of the tape applying operation.
On the other hand, the front door sash portion 17 is normally symmetric in left and rights of the vehicular body. Therefore, depending upon left- and right-cut, the direction to pass the adhesive tape 11 relative to the tape guide portion 14 is reversed from the condition shown in Figs. 5 and 7, and the 23 - main body 22 is shifted in the reverse direction relative to the front door sash portion 17. Thus, the shown embodiment of the tape application device can be adapted for left and right front door sash portions 17 without requiring any modifications.
Furthermore, when the width and configuration of the front door sash portion 17 are differentiated significantly depending upon kind of the vehicle, the shown embodiment of the tape application device can be adapted or adjusted by exchanging the positioning rollers 18 and theholding roller 32 with those having different size and/or configuration.
Although the invention has been illustrated and described with respect to exemplary embodiment thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions and additions may be made therein and thereto, without departing from the spirit and scope of the present invention. Therefore, the present invention should not be understood as limited to the specific embodiment set out above but to include all possible embodiments which can be embodied within a scope encompassed and equivalents thereof with respect to the feature set out in the appended claims. For instance, while shown embodiment employs the cylindrical pressure drum 16 - 24 1 in the pressing portion, a flat plate form depression member may also applicable. Also, in the shown embodiment, as projecting and retracting means for the pressure drum 16, the stepped shaft 38 and the corresponding stepped bore are employed. However, any other construction with permits the pressure drum 16 to be projected and retracted associated with sliding operation of the sliding block can be employed.
