The present invention relates to adhesive transfer devices, and more particularly to such an adhesive transfer device, which is capable of performing either of spot-like or point-like transfer and linear transfer of an adhesive carried on a backing material.
Conventionally, transfer tapes having an adhesive carried on one surface of a backing material have been used for pasting posters, pictures and the like or sealing envelopes. The transfer tapes are wound around a reel and set in a case of a transfer device before use.
The transfer device for transferring the adhesive from the transfer tape onto a transfer target surface includes a case having contained therein a rotatable supply reel around which a transfer tape having an adhesive provided on one surface of a backing material is wound, a rotatable take-up reel for taking up a portion of the backing material unwound from the supply reel, and a transfer head for transferring the adhesive of the transfer tape unwound from the supply reel onto the transfer target surface and having a flat transfer surface.
One example of such transfer device is disclosed in Japanese Patent Laid-open Publication (JP-A) No. 11-227386, which can perform spot-like transfer of the adhesive of the transfer tape to the transfer target surface by bringing the transfer head into contact with a desired position on the transfer target surface and compression deforming an elastic member of the transfer head by pressing. When performing linear transfer of the adhesive to the transfer target surface, a corner edge of the transfer surface is brought into contact with the transfer target surface and the body case of the transfer device is moved in a direction parallel to the transfer target surface with the body case pressed in a direction toward the transfer target surface.
Another example of the transfer devices is disclosed in International Publication (WO-A1) No. 2006-516931, which comprises a transfer head including a plurality of rollers that are rotatable about substantially parallel axes spaced apart from one another, and a closed-loop belt that is trained about the periphery of the rollers.
The transfer device described in JP 11-227386 A1 needs to be inclined relative to the transfer target surface during linear transfer operation so as to ensure that the corner edge of the flat transfer surface can move in a direction parallel to the transfer target surface with the corner edge pressed onto the transfer target surface. Movement of the transfer device while being kept in an inclined position renders a contact state in a width direction of the transfer tape unstable, which will result in insufficient transfer of the adhesive to the transfer target surface. Furthermore, since the corner edge of the flat transfer surface is forced against the transfer target surface, the transfer surface may be damaged due to application of excessively large force or pressure to a small area of the transfer target surface.
The transfer device described in WO 2006-516931 A1 allows the transfer head to be pressed onto the transfer target surface with a small force as compared to the transfer device of JP 11-227386 A1 because of the transfer head which is composed of a plurality of rollers that are rotatable about substantially parallel axes spaced apart from one another, and a closed-loop belt that is trained about the periphery of the rollers. However, due to the structure of the transfer head including the closed-loop belt trained around the periphery of the plural spaced rollers, the transfer device described in WO 2006-516931 A1 can encounter a problem that when the flat transfer surface of the transfer head is pressed onto the transfer target surface for performing spot-line transfer of the adhesive, part of the closed-loop located between the adjacent rollers tends to distort in a direction away from the transfer target surface, which will bring about insufficient transfer of the adhesive to the transfer target surface.
The present invention has been conceived in view of the foregoing problems and is aimed at the provision of an adhesive transfer device which can reliably transfer by simple operation an adhesive onto a transfer target surface by either of spot-like transfer and linear transfer that are alternately selected.
To solve the foregoing problems, the present invention provides an adhesive transfer device which includes a case, a supply reel rotatably mounted to the case and having a wound supply of transfer tape wound thereon, the transfer tape having a backing material and an adhesive provided on one surface of the backing material, a take-up reel rotatably mounted to the case for taking up a portion of the backing material of the transfer tape unwound from the supply reel, and a transfer head mounted to the case for transferring the adhesive of the transfer tape unwound from the supply reel onto a transfer target surface, characterized in that said transfer head has one end pivotally connected to the case and includes a first transfer section provided at a free end portion of the transfer head and having a circular arc-shaped contact surface for mutual contact between the first transfer section and the transfer tape, a second transfer section disposed between the first transfer section and a pivot portion of the transfer head and having a flat transfer surface, and a spring member for urging the free end portion of the transfer head toward the transfer target surface, wherein the transfer head is configured to selectively perform either of spot-like transfer of the adhesive onto the transfer target surface by first pressing the second transfer section onto the transfer target surface against the resilience of the spring member and subsequently moving the second transfer section back away from the transfer target surface, and linear transfer of the adhesive onto the transfer target surface by moving the first transfer section with the first transfer section pressed onto the transfer target surface by the resilience of the spring member.
With the adhesive transfer device thus arranged, the second transfer section is pressed onto the transfer target surface against the resilience of the spring member and subsequently the second transfer surface is moved back away from the transfer target surface whereupon that part of the adhesive of the transfer tape which has been pressed onto the transfer target surface by the flat transfer surface of the second transfer section is transferred to the transfer target surface in a spot-like state. Furthermore, the transfer tape unwound from the supply reel is continuously pressed by the first transfer section onto the transfer target surface by moving the first transfer section with the first transfer section pressed onto the transfer target surface by the resilience of the spring member, so that the adhesive of the transfer tape is transferred onto the transfer target surface in a linear fashion.
The first transfer section may be fixedly mounted to the transfer head provided that the transfer surface is shaped into a circular arc. However, it is preferable according to the present invention that the first transfer section comprises a roller rotatably mounted to the transfer head.
This arrangement ensures that the first transfer section can move smoothly on the transfer target surface after it is pressed onto the transfer target surface.
Preferably, the flat transfer surface of the second transfer section is formed by an elastic plate member.
With this arrangement, when the transfer surface of the second transfer section is pressed onto the transfer target surface, it is possible to take up or cancel out surface irregularities of the transfer target surface by a synergetic effect generated by the resilience of the spring member and the elastic deformation of the elastic plate member.
It is preferable according to the invention that a slippery cover member for smoothening movement of the transfer tape is attached to each of the transfer surface of the second transfer section and that part of the transfer head which excludes the first transfer section and which is subjected to mutual contact with the transfer tape.
With this arrangement, contact friction between the transfer head and the transfer target surface can be reduced, which will insure smooth movement of the transfer tape.
According to the invention, the adhesive transfer device may further comprise a take-up mechanism for taking up the transfer tape around the take-up reel when the second transfer surface is moved back away from the transfer target surface. Preferably, the take-up mechanism includes a sector gear mounted coaxially with the pivot portion of the transfer head, a supply gear that can mesh with the sector gear and is mounted coaxially with a cylindrical body of the supply reel for transmitting a rotary motion to the supply reel only in an unwinding direction of the transfer tape, a driving gear mounted coaxially with the supply gear, and a driven gear held in driven mesh with the driving gear via an intermediate gear and mounted coaxially with a cylindrical body of the take-up reel.
With this arrangement, the transfer surface of the second transfer section is first brought into contact with the transfer target surface and subsequently forced against the transfer target surface during which time the transfer head pivots in a direction to turn the sector gear in the same direction. The sector gear comes into meshing engagement with the supply gear mounted coaxially with the cylindrical body of the supply reel and turns the supply gear and the driving gear concurrently while the supply reel is kept immovable against rotation. With this rotation of the driving gear, the driven gear mounted coaxially with the cylindrical body of the take-up reel is driven via the intermediate gear to rotate in a direction to ensure that a portion of the transfer tape extending between the transfer head and the take-up reel is taken up around the take-up reel.
According to the invention, the adhesive transfer device may further comprise a confirmation sound generating mechanism for generating a confirmation sound when the transfer surface of the second transfer section is pressed against the resilience of the spring member onto the transfer target surface over the entire area thereof. Preferably, the confirmation sound generating mechanism includes a pivotally movable member mounted coaxially with the pivot portion of the transfer head, and a resilient pawl member fixed at one end thereof to the case and intermittently engageable with the pivotally movable member when the transfer surface of the second transfer section is pressed onto the transfer target surface over the entire area thereof and generating a sound by oscillation upon intermittent engagement with the pivotally movable member. The pivotally movable member may be formed by the sector gear that can mesh with the supply gear which is mounted coaxially with the pivot portion of the supply reel and rotatable only in the unwinding direction of the transfer tape.
With this arrangement, when the transfer surface of the second transfer section is brought into contact with the transfer target surface, the transfer head pivots to turn the pivotally movable member in one direction. When the entire area of the transfer surface comes in contact with the transfer target surface, the pivotally movable member intermittently engages the resilient pawl member to thereby cause the resilient pawl member to generate a sound by oscillation. The thus generated sound enables the user to confirm that the entire area of the transfer surface of the second transfer section has come in contact with the transfer target surface. In the case where the pivotally movable member is formed by the sector gear that can mesh with the supply gear which is mounted coaxially with the pivot portion of the supply reel and rotatable only in the unwinding direction of the transfer tape, a transfer tape take-up_mechanism can share the same structural member with the confirmation sound generating mechanism.
By virtue of the foregoing structure, the adhesive transfer device of the present invention is able to achieve various advantageous effects, as enumerated below.
(6) Furthermore, according to the invention, during the spot-like adhesive transfer operation, pivotal movement of the transfer head causes the pivotally movable member to move into intermittent engagement with the resilient pawl member and generate a sound by oscillation of the resilient pawl member. The thus generated sound enables the user to confirm that the entire area of the transfer surface of the second transfer section has come into contact with the transfer target surface. Thus, in addition to the advantageous effect mentioned in (1) through (5) above, the spot-like adhesive transfer operation can be achieved with high reliability. In the case where the pivotally movable member is formed by the sector gear that can mesh with the supply gear which is mounted coaxially with the pivot portion of the supply reel and rotatable only in the unwinding direction of the transfer tape, the confirmation sound generating mechanism can share the same structural member with the transfer tape take-up mechanism. This will achieve reduction in number of the structural members and downsizing of the adhesive transfer device.

As shown in
The transfer tape 1 is formed by a pressure-sensitive tape having a backing material 2 formed of a paper liner, for example, and an adhesive 3 consisting of acrylic pressure sensitive adhesive, for example, provided on one surface of the backing material 2 in a pattern arranged either zigzag or at regular intervals in both longitudinal and transverse directions of the backing material 2.
As shown in
The base portion 12 of the case body 11 is provided with a first support shaft 18a disposed at substantially the central portion of the base member 12 for rotatably supporting thereon the supply reel 20, a second support shaft 18b disposed at a position offset from the first support shaft 18a toward one end of the base portion 12 for rotatably supporting thereon the take-up reel 30, and a third support shaft 18c disposed adjacent to the opposite end of the base portion 12 located remotely from the second support shaft 18b for pivotally supporting thereon the transfer head 40.
A driving gear 51 and a supply gear 52 having a diameter smaller than that of the driving gear 51 are rotatably mounted on the first support shaft 18a. The driving gear 51 has a hub 51a provided protuberantly therefrom and rotatably mounted on the first support shaft 18a, and the supply reel 20 is removably mounted on the hub 51a. The supply gear 52 and the driving gear 51 have a built-in clutch mechanism which is configured to transfer a rotary motion to the supply reel 20 in a single direction (unwinding direction) to unwind the transfer tape 1 from the supply reel 20. As shown in
A driven gear 54 is rotatably mounted on the second support shaft 18b. The driven gear 54 has a flanged hub 54a provided protuberantly therefrom and rotatably mounted on the second support shaft 18b, and the take-up reel 30 is removably mounted on the hub 54a via a reverse rotation preventing mechanism 56 and a brake mechanism 57.
In the illustrated embodiment, as shown in
The take-up reel 30 has a plurality of small holes 32 formed in a front-side flange 31 thereof at regular intervals along a peripheral edge of the flange 31. The flange 31 has an arrow mark 33 provided on a front surface thereof for indicating a take-up direction. By thus providing the small holes 32 and the arrow mark 33 on the flange 31 of the take-up reel 30, if the transfer tape 1 becomes slack during use, the user can manually take up the slack by turning the take-up reel 30 in the take-up direction using a pin (not shown) which is inserted though a window opening 15a formed in the cover member 15 of the case 10 into one of the small holes 32.
The sector gear 41 is rotatably mounted on the third support shaft 18c. The sector gear 41 has a central hub 41a provided protuberantly therefrom and rotatably mounted on the third support shaft 18c. A pivot shaft 42 projecting from one end of the transfer head 40 is fitted in the hub 41a. The sector gear 41 further has a circular arc-shaped grooved portion 43 formed in a concentric relation to the sector gear 41 and protruding from an intermediate portion of a front surface of the sector gear 41. A circular arc-shaped projection 44 formed on the transfer head 40 is fitted in an opening or groove formed in the circular arc-shaped grooved portion 43 so that the transfer head 40 and the sector gear 41 are integrated into a single unitary member.
The take-up mechanism 50 has the sector gear 41 mounted on a pivot portion of the transfer head 40, the supply gear 52 that can mesh with the sector gear 41 and is mounted coaxially with a cylindrical body of the supply reel 20 for transmitting rotation to the supply reel a single direction (unwinding direction) to unwind the transfer tape 1, the driving gear 51 mounted coaxially with the supply gear 52, and the driven gear 54 which is in driven mesh with the driving gear 51 via the intermediate gear 53 and mounted coaxially with a cylindrical body of the take-up reel 30.
With the take-up mechanism 50 thus constructed, when a transfer surface 45c of a second transfer section 45b of the transfer head 40 is pressed against the transfer target surface 4, the transfer head 40 undergoes pivotal movement to turn the sector gear 41 in one direction. Thus, the sector gear 41 first comes into meshing engagement with the supply gear 52 and then turns the supply gear 52 and the driving gear 51 concurrently while the supply reel 20 is kept immovable against rotation. Rotation of the driving gear 51 causes the driven gear 54 to rotate via the intermediate gear 53 in the take-up direction so that a portion of the transfer tape 1 extending between the transfer head 40 and the take-up reel 30 is taken up around the take-up reel 30. A slack of the transfer tape 1, which is produced due to forced pivotal movement of the transfer head 40 occurring against the force or resilience of the spring member 46 during the spot-like transfer of the adhesive, can thus be taken up or removed.
The sector gear 41, supply gear 52, driving gear 51, intermediate gear 53 and driven gear 54, which jointly form the take-up mechanism 50, are each formed by a material having high tensile and bending strengths, such as a polyacetal resin or the like synthetic resin.
Since the pivot shaft 42 of the transfer head 40 is fitted in the hub 41a of the sector gear 41 rotatably mounted on the third support shaft 18c, the transfer head 40 has one end pivotally supported on the third support shaft 18c protruding from the base portion 12 of the case 10. The transfer head 40 includes a first transfer section 45a formed at a free end portion thereof and having a circular arc-shaped contact surface for mutual contact with the transfer target surface 4, the second transfer section 45b disposed between the first transfer section 45a and the pivot portion (corresponding to the third support shaft 18c) and having a flat transfer surface 45c, and the spring member 46 for urging the free end portion of the transfer head 40 toward the transfer target surface 4. The transfer head 40 is made up of a head base member 40a including the circular arc-shaped projection 44 protruding from a rear surface thereof and engaged with the circular arc-shaped grooved portion 43 of the sector gear 41, a head front member 40b connected to a front surface side of the head base member 40a, and a head cover 40c fitted over the thus connected head base member 40a and head front member 40b. The head base member 40a, head front member 40b and head cover 40c are each formed of a member made from a synthetic resin such as impact-resistant polystyrene resin.
In the illustrated embodiment, the first transfer section 45a includes a rotary shaft 48a rotatably received in an opening 47 formed at the free end portion of the transfer head 40, and a transfer roller 48b of silicone resin fitted around an outer circumferential surface of the rotary shaft 48a.
The second transfer section 45b is formed by a headpiece 49b of trapezoidal shape in cross section fitted into a cutout groove 49a provided between the first transfer section 45a and the pivot portion of the transfer head 40. The headpiece 49b is formed from a synthetic resin such as impact-resistant polystyrene resin and has a front surface forming the transfer surface 45c. An elastic plate such as a cushion member 90 formed, for example, by a nonwoven fabric or a synthetic rubber is attached to the transfer surface 45c. The cushion member 90 has a front surface side, and a first slippery cover member 101 for smoothening movement of the transfer tape 1 is attached to the front surface side of the cushion member 90. The second transfer section 45b need not necessarily be formed by the headpiece 49b but may be formed integrally with the transfer head 40.
Furthermore, a second slippery cover member 102 for smoothening movement of the transfer tape 1 is attached to that part of the transfer head 40 which excludes the first transfer section 45a and which is subject to friction contact with the transfer tape 1. A third slippery cover member 103 for smoothening movement of the transfer tape 1 is also attached to that part of the recessed portion 16 of the cover member 15 which faces the first transfer section 45a.
By thus providing the first and second slippery cover members 101 and 102 on the transfer head 40 in combination with the third slippery cover member 103 provided on that part of the cover member 15 facing the first transfer section 45a, movement of the transfer tape 1 on and along the transfer head 40 is made smooth and the transfer tape 1 is protected against damage which may otherwise occur due to undue friction between itself and the transfer head 40.
The spring member 46 is formed by, for example, a torsion coil spring fitted loosely around the hub 41a of the sector gear 41 rotatably mounted on the third support shaft 18c and having one end engaged with a recessed locking portion 12a protruding from the base portion 12 of the case body 11, the other end of the torsion coil spring 46 being anchored by a portion of the transfer head 40. With the spring member 46 thus arranged, the free end portion of the transfer head 40 is urged by the force or resilience of the spring member 46 toward the transfer target surface 4. The spring member 46 may be formed by a spring other than the torsion coil spring provided that it can produce a resilient force tending to urge the free end portion of the transfer head 40 including the first transfer section 45a toward the transfer target surface 4.
The confirmation sound generating mechanism 60 includes a pivotally movable member, such as the sector gear 41, mounted coaxially with the pivot portion of the transfer head 40, and a resilient pawl member 61 fixed at one end thereof to the base portion 12 of the case body 11 and intermittently engageable with the sector gear 41 when the entire area of the second transfer section 45b is pressed onto the transfer target surface 4 and capable of generating a sound by oscillation upon intermittent engagement with the sector gear 41. In the illustrated embodiment, the resilient pawl member 61 is formed by a substantially elliptical fixed portion 63 having a pair of engagement holes 62 fitted respectively with a pair of retaining posts 12b protruding from the base portion 12 of the case body 11, and a pawl portion 64 extending downwards from an upper end of the fixed portion 63 to assume an arcuately curved configuration and terminating in a pointed end. The resilient pawl member 61 is formed from a resilient material having high tensile and bending strengths, such as a polyacetal resin or the like synthetic resin.
Since the confirmation sound generating mechanism 60 is comprised of the sector gear 41 and the resilient pawl member 61 as described above, the confirmation sound generating mechanism 60 shares the sector gear 41 with the take-up mechanism 50. Therefore, it is possible to reduce the number of structural components or members and downsize the adhesive transfer device.
For installation into the case body 11, the sector gear 41 forming a common part of the take-up mechanism 50 and confirmation sound generating mechanism 60, the supply gear 52, driving gear 51, intermediate gear 53, driven gear 54 and resilient pawl member 61 are mounted on the partition plate 14 in advance and subsequently they are placed into the case body 11 together with the partition plate 14.
More particularly, as shown in
Subsequently, the sector gear 41, supply gear 52, driving gear 51, intermediate gear 53, driven gear 54, resilient pawl member 61, supply reel 20 and take-up reel 30 carried on the partition plate 14 are accommodated within the case body 11. In this instance, resiliently deformable locking prongs 14e projecting from the rear surface of the partition plate 14 are brought into snapping engagement with recessed retaining portions 12c protruding from the base portion 12 of the case body 11 so that the partition plate 14 is secured to the case body 11 (see
While the adhesive transfer device is not in use, a cap 19 formed from a synthetic resin material such as polypropylene is attached to a common side of the case body 11 and cover member 15 including the recessed portion 16 of the cover member 15 so that a portion of the transfer head 40 projecting from the recessed portion 16 of the cover member 15 is covered with the cap 19. The cap 19 is made transparent in the same manner as the case body 11 and cover member 15.
According to the foregoing construction, an internal space of the case 10 is divided by the opaque partition plate 14 into a front surface side and a rear surface side, and therefore, it is possible to place the sector gear 41, supply gear 52, driving gear 51, intermediate gear 53, driven gear 54 and resilient pawl member 61 on the rear surface side and also place the supply reel 20, take-up reel 30 and transfer tape 1 on the front surface side. With this arrangement, the supply reel 20, take-up reel 30 and transfer tape 1 can be visually observed through the transparent case 10 from the front surface side thereof. Similarly, the sector gear 41, supply gear 52, driving gear 51, intermediate gear 53, driven gear 54 and resilient pawl member 61 can be visually observed through the transparent case 10 from the rear surface side thereof.
When the transfer tape 1 is to be replaced, as shown in
The replacement cartridge 70 is formed from a synthetic resin material such as polypropylene. As shown in
When the transfer tape 1 is to be replaced by using the replacement cartridge 70 of the foregoing construction, a supply reel 20 and a take-up reel 30 that are rotatably retained by the locking prongs 81, 82 at opposite ends of the tape cartridge 80 with a new transfer tape 1 wound on the supply reel are temporarily held by the replacement cartridge 70. Then, as shown in
Operation modes of the adhesive transfer device of the foregoing embodiment will next be described below in detail.
In order to perform spot-like transfer of the adhesive 3 onto the transfer target surface 4, first, the adhesive transfer device is placed above a desired transfer position on the transfer target surface 4 (see
Then, the free end of the transfer head 40, namely the first transfer section 45a is brought into contact with the transfer target surface 4, and while keeping this condition, the second transfer section 45b is brought into contact with the transfer target surface 4 against the resilience of the spring member 46 (see
The angular movement of the sector gear 41 caused due to pivotal movement of the transfer head 40 brings the sector gear 41 into meshing engagement with the supply gear 52 and then turns the supply gear 52 and the driving gear 51 concurrently while the supply reel 20 is kept immovable against rotation. Rotation of the driving gear 51 causes the driven gear 54 to rotate via the intermediate gear 53 and the take-up reel 30 to also rotate in the take-up direction so that a portion of the transfer tape 1 (to be more precise, the backing material 2 of the transfer tape 1) extending between the take-up reel 30 and the free end portion of the transfer head 40 is taken up around the take-up reel 30. A slack of the transfer tape 1 occurring when the transfer head 40 pivots against the force or resilience of the spring member 46 can thus be taken up or removed.
Then, the second transfer section 45b is moved back away from the transfer target tape 4 and this movement enables the adhesive 3 of the transfer tape 1 to be transferred onto the transfer target surface 4 in a spot-like fashion (see
In order to perform linear transfer of the adhesive 3 onto the transfer target surface 4, the adhesive transfer device is first placed above a desired transfer position on the transfer target surface 4 (see
Then, the first transfer section 45a is brought into contact with the transfer target surface 4 and then depressed to such an extent that the first transfer section 45a is kept into pressure contact with the transfer target surface 4 by the resilience of the spring member 46 (see
When a desired length of adhesive 3 has been transferred onto the transfer target surface, advancing movement of the adhesive transfer device is terminated and the first transfer section 45a is moved back away from the transfer target surface 4 (see
Although in the illustrated embodiment discussed above, the adhesive 3 of the transfer tape 1 is provided on the backing material 2 in a pattern arranged either zigzag or at regular intervals in both longitudinal and transverse directions of the backing material 2, arrangement of the adhesive 3 should by no means be limited to the one shown in the illustrated embodiment but may include any other pattern in which the adhesive is carried on one surface of a backing material 2 in the form of, for example, a plurality of parallel spaced strips of adhesive material provided at predetermined intervals along the length of the backing material 2, or a row of pieces of adhesive material having a smaller surface area than the transfer surface 45c.
According to the invention, since the adhesive of the transfer tape can be transferred onto the transfer target surface either in a spot-like fashion by pressing or stamping the transfer surface of the second transfer section onto the transfer target surface against the resilience of the spring member and subsequently moving the second transfer section back away from the transfer target surface, or alternatively in a linear fashion by moving the first transfer section on the transfer target surface with the first transfer section pressed onto the transfer target surface by the resilience of the spring member, spot-like transfer of the adhesive to the transfer target surface and linear transfer of the adhesive to the transfer target surface can be selectively performed by simple operation with high reliability.
