Abstract
Description
[Technical Field]
[0001] The present invention relates to a transfer tool. [Background technology]
[0002] Conventionally, a transfer device has been known that includes a supply reel from which a transfer tape having a transfer material such as glue attached thereto is supplied, a take-up reel for taking up the transfer tape supplied from the supply reel, and a reel linkage mechanism that links the rotation of the supply reel and the take-up reel (see, for example, Patent Document 1).
[0003] In some transfer tools of this type, a slip clutch is configured to optimize the tension of the transfer tape by interposing a coil spring between the payout gear that constitutes the reel interlocking mechanism and a core member that can support the payout reel. While a slip clutch of this configuration can perform an excellent function of optimizing the tension of the tape, it has the dilemma that the coil spring is an essential component and therefore there is a certain limit to how much the number of parts and manufacturing man-hours can be reduced.
[0004] Therefore, attempts have been made to realize a slip clutch by simply engaging the payout gear and the payout reel without using a coil spring.
[0005] However, in conventional slip clutches, excessive deformation or damage to specific parts can occur when assembling the payout gear and payout reel, preventing the intended function of the slip clutch from being properly achieved. As a result, the precision of the slip clutch can vary from product to product, making it difficult to accurately and appropriately assemble the components that make up the slip clutch.

DETAILED DESCRIPTION OF THE INVENTION
[0022] Hereinafter, one embodiment of the present invention will be described with reference to FIGS.
[0023] In this embodiment, the present invention is applied to a transfer tool for transferring a transfer material, namely, glue (not shown), to a transfer target surface (not shown) such as paper. The transfer tool is configured so that transfer tape T is paid out from a payout reel C, passes through a transfer head B, and is wound onto a take-up reel D.
[0024] The transfer device is configured to transfer adhesive from the substrate t1 to the surface to be transferred by pressing the transfer tape T, which has adhesive applied to one side of a strip-shaped substrate t1, against the surface to be transferred using a transfer roller b4 provided at the tip of the transfer head B, and flowing and running the transfer tape T from the upstream side (the side of the supply reel C) to the downstream side (the side of the take-up reel D).
[0025] The transfer device comprises a case A capable of storing transfer tape T inside, a transfer head B disposed at the front end of the case A, a supply reel C stored in the case A and wound with transfer tape T holding adhesive, a take-up reel D stored in the case A for winding up the transfer tape T that is paid out from the supply reel C and passes through the transfer roller b4 of the transfer head B, and a reel linkage mechanism E that links the rotation of the supply reel C and the take-up reel D.
[0026] The reel linkage mechanism E is provided with a slip clutch S that causes slippage, i.e., relative rotation, between the payout gear M, which is a first rotating member that rotates around the first support axis j1, which is a common axis provided in the case A, and the payout reel C, which is a second rotating member, thereby optimizing the degree of tension of the transfer tape T.
[0027] Each component of the transfer tool will be described below.
[0028] <Case A> Case A is made of synthetic resin and has an internal storage space sp that can accommodate the supply reel C and the take-up reel D. Case A houses the supply reel C, supply gear M, take-up reel D, take-up gear N, and slip clutch S provided between the supply gear M and the supply reel C, which constitute the reel interlocking mechanism E.
[0029] The case A has left and right side walls 1 and 2, an upper wall 3 arranged between the upper ends of the left and right side walls 1 and 2, a rear wall 4 arranged between the rear ends of the left and right side walls 1 and 2, and a lower wall 5 arranged between the lower ends of the left and right side walls 1 and 2.
[0030] An opening 6 is formed on the front side of the case A for leading the transfer tape T to the transfer roller b4 of the transfer head B and for introducing the transfer tape T that has passed through the transfer roller b4 of the transfer head B into the interior of the case A.
[0031] The case A is composed of a left case member L and a right case member R attached to the left case member L.
[0032] The left case member L has a left side wall 1 and includes an upper left wall portion 31 that forms the upper wall 3, a rear left wall portion 41 that forms the rear wall 4, and a lower left wall portion 51 that forms the lower wall 5.

[0034] In this embodiment, the upper right wall portion 32, the right rear wall portion 42, and the right lower wall portion 52 provided on the right case member R are set to be longer in the horizontal direction than those of the left case member L so that they can form the main parts of the upper wall 3, the rear wall 4, and the lower wall 5.
[0035] In addition, the right side view of FIG. 5 shows the state in which the right case member R has been removed for the convenience of explaining the internal structure of the transfer tool.
[0036] A first support shaft j1 for rotatably supporting a payout reel C and a payout gear M that constitute a reel interlocking mechanism E is provided to protrude from the inner surface of the left side wall 1.
[0037] A second support shaft j2 protrudes from the inner surface of the left side wall 1 and rotatably supports the winding reel D and winding gear N that constitute the reel interlocking mechanism E. The second support shaft j2 is disposed behind the first support shaft j1.
[0038] The tip ends of the first and second support shafts j1 and j2 are connected to the inner surface of the right side wall 2, respectively.
[0039] A protective cover F that can cover the transfer head B when not in use is rotatably supported on the case A.
[0040] <Transfer head B> The transfer head B comprises left and right upright walls b1 and b2 provided on the case A, a roller support shaft b3 installed between the tips of the left and right upright walls b1 and b2, and a cylindrical transfer roller b4 supported by the roller support shaft b3.
[0041] The left upright wall b1 is provided integrally with the left case member L, and the right upright wall b2 is provided integrally with the right case member R.
[0042] The roller support shaft b3 is a cylindrical member protruding from the left case member L. The roller support shaft b3 is formed integrally with the left standing wall b1. The protruding end of the roller support shaft b3 is connected to the right standing wall b2.
[0043] The transfer roller b4 is cylindrical and has a shaft insertion hole that penetrates in the left-right direction and into which the roller support shaft b3 is inserted. The transfer roller b4 can rotate around the roller support shaft b3 during the transfer operation.
[0044] <Payment reel C> The payout reel C constitutes the reel interlocking mechanism E. The payout reel C is fitted onto the payout gear M. The payout reel C is rotatably supported on a first support shaft j1 protruding from the case A via the payout gear M. In this embodiment, the payout reel C is disposed in front of the take-up reel D.
[0045] The payout reel C comprises a cylindrical payout reel body c1 that extends in the left-right direction and has transfer tape T wound around its outer periphery, left and right side plate portions c2 provided in a flange-like shape on both left and right ends of the payout reel body c1, and an engaged portion c3 that protrudes inward from the inner periphery of the payout reel body c1, i.e., toward the center of rotation, in a flange-like shape and can engage with a separation restriction portion m2 provided on the payout gear M. The payout reel body c1, left and right side plate portions c2, and engaged portion c3 are integrally formed from synthetic resin.
[0046] The inner peripheral surface of the payout reel body c1 is provided with an abutment portion G against which the elastic engagement portion Q of the payout gear M elastically abuts. The abutment portion G is set in the widthwise center of the cylindrical inner peripheral surface of the payout reel body c1.
[0047] The left and right side plate portions c2 are capable of positioning the transfer tape T wound around the payout reel main body portion c1. The left and right side plate portions c2 are generally doughnut-shaped in side view.
[0048] The outer surface of the left side plate portion c2 facing the payout gear main body m1 is adapted to come into contact with a contact protrusion m12 protruding from the payout gear main body m1. The payout reel C is positioned relative to the payout gear M by coming into contact with the contact protrusion m12.
[0049] Additionally, recessed holes c21 are provided in parallel on the outer surface of the peripheral edge of the right side plate portion c2 to correct any looseness that may occur in the transfer tape T. The recessed holes c21 are of a known configuration that allows the slip clutch S to be forcibly operated by rotating the payout reel C.
[0050] The engaged portion c3 is annular in side view. The engaged portion c3 is located closer to the right side wall 2 than the abutment portion G on the payout reel body c1. The engaged portion c3 includes an inward extending portion c31 that extends inward from the payout reel body c1, i.e., in a direction approaching the axis cn, and a cylindrical portion c32 provided at the extending end of the inward extending portion c31. The cylindrical portion c32 is cylindrical and has a smaller diameter than the payout reel body c1.
[0051] The payout reel C is configured so as not to come off from the payout gear M by directly engaging the cylindrical portion c32 of the engaged portion c3 with the come-off restricting portion m2 provided on the payout gear M.
[0052] <Take-up reel D> The take-up reel D takes up the transfer tape T that has been fed from the supply reel C via the transfer roller b4 of the transfer head B. The take-up reel D has a roughly cylindrical take-up reel body d1 that extends in the left-right direction and is capable of taking up the transfer tape T around its outer periphery, and left and right flanges d2, d3 provided on both left and right ends of the take-up reel body d1. The take-up reel D is rotatably supported on a second support shaft j2 that protrudes from the case A.
[0053] A winding gear N is integrally provided on the outside of one of the flanges, i.e., the left flange d2. A claw d4 for preventing reverse rotation is provided on the outside of the other flange, i.e., the right flange d3, and can be engaged with a claw engagement portion (not shown) provided on the inner surface of the right side wall 2.
[0054] <Reel Linkage Mechanism E> The reel linkage mechanism E is composed of a payout reel C on which is wound transfer tape T with adhesive retained before transfer, a payout gear M rotatably supported on a first support shaft j1 and capable of rotating together with the payout reel C, a take-up gear N rotatably supported on a second support shaft j2 and meshing with the pay-out gear M, a take-up reel D integrally provided on the side with the take-up gear N and which takes up the transfer tape T with adhesive released after transfer, and a slip clutch S provided between the pay-out gear M and the pay-out reel C.
[0055] <Feeding gear M> The payout gear M has teeth ha on its outer periphery and a shaft hole H in its center into which the first support shaft j1 is inserted.
[0056] The payout gear M includes a payout gear main body m1 having a circular outer periphery on which a plurality of teeth ha are arranged in a row for meshing with the take-up gear N, a detachment prevention portion m2 having an axial hole H into which the first support shaft j1 is inserted and whose tip can engage with the cylindrical portion c32 of the payout reel C, a loop structure m3 arranged outside the detachment prevention portion m2, i.e., away from the axis cn, and formed in a continuous loop shape so as to surround the axis cn of the first support shaft j1, and a connecting portion m4 connecting the payout gear main body m1 and the detachment prevention portion m2 and between the loop structure m3 and the detachment prevention portion m2 so as to separate the detachment prevention portion m2 and the loop structure m3. The payout gear main body m1, detachment prevention portion m2, loop structure m3, and connecting portion m4 are integrally formed from synthetic resin.
[0057] The payout gear main body m1 comprises an outer annular portion m11 having a circular ring shape and a plurality of teeth ha arranged on its outer peripheral edge that can mesh with the winding gear N; a contact protrusion m12 that is protruded from the inner peripheral edge of the outer annular portion m11, i.e., closer to the axis cn than the teeth ha, and that can position the payout reel C by the payout reel C coming into contact with it; a plurality of, i.e., three, through holes I formed at regular intervals closer to the axis cn than the outer annular portion m11; and a plurality of, i.e., three, plate-shaped portions m13 that are interposed between the three through holes I and extend from the inner edge of the outer annular portion m11 in a direction approaching the axis cn.
[0058] The contact protrusion m12 is an annular portion protruding from the outer annular portion m11. The contact protrusion m12 cooperates with the locking claw m22 of the separation restricting portion m2 to position the payout reel C fitted onto the payout gear M relative to the payout gear M.
[0059] The through holes I are formed at three locations at regular intervals in the rotation direction of the payout gear M. The through holes I are provided between the outer annular portion m11 and the separation prevention portion m2. The loop structure portion m3 straddles the through holes I and connects adjacent plate-shaped portions m13.
[0060] The through hole I is provided in an area outside the separation prevention portion m2 having the axial hole H. The through hole I is provided so as to allow the three elastic engagement portions Q provided in the loop structure portion m3 to elastically deform in the radial direction.
[0061] The through hole I has an inner through hole portion i1 arranged adjacent to and radially inward of the elastic engagement portion Q in a side view, an outer through hole portion i2 arranged adjacent to and radially outward of the elastic engagement portion Q in a side view, and a central through hole portion i3 arranged adjacent to and overlapping with the elastic engagement portion Q in a side view.
[0062] The separation prevention portion m2 is capable of preventing the separation of the payout reel C fitted onto the payout gear M. In other words, the separation prevention portion m2 is intended to prevent the payout reel C from coming off. The separation prevention portion m2 also serves as a payout reel support shaft that can rotatably support the payout reel C.
[0063] The separation prevention portion m2 is provided at a position closer to the first support shaft j1 than the loop structure portion m3 having the elastic engagement portion Q. In other words, the separation prevention portion m2 is provided at a different position on the payout gear M from the loop structure portion m3.
[0064] The detachment prevention portion m2 comprises a detachment prevention portion main body m21 having an approximately cylindrical shape erected in the direction of the axis cn, and three locking claws m22 that protrude from the outer surface of the detachment prevention portion main body m21 and engage with the engaging portion c3 of the payout reel C to prevent the payout reel C from coming off.
[0065] A notch ka is formed on the protruding end of the separation restricting portion main body m21 to temporarily elastically deform the portion where the locking claw m22 is provided when the payout reel C is attached.
[0066] The locking pawls m22 are provided at three locations spaced at regular intervals. Each locking pawl m22 has a reel engagement surface me that faces the payout gear main body m1 and can slidably come into contact with the end surface of the cylindrical portion c32 of the payout reel C.
[0067] The loop structure m3 has a closed loop structure and is disposed outside the separation prevention portion m2, i.e., at a position away from the axis cn. The loop structure m3 has a roughly triangular shape in side view. The loop structure m3 has elastic engagement portions Q disposed at three locations farthest from the axis cn.
[0068] The loop structure portion m3 comprises multiple, i.e., three, base portions U erected in the direction of the axis cn from the inner end of the plate-shaped portion m13 in the payout gear main body portion m1, and an elastic engagement portion Q bridged between the tip ends of adjacent base portions U.
[0069] The base portion U has a partially cylindrical shape that is curved outwardly in a side view. The base portions U are arranged at three locations at regular intervals in the rotational direction of the payout gear M so as to surround the axis cn. The base portions U form a portion that rises from the plate-shaped portion m13 of the payout gear main body m1. A reinforcing rib ua protrudes from the outer peripheral surface of the base portion U.
[0070] The elastic engagement portion Q is configured to be easily elastically deformed in the radial direction. The elastic engagement portion Q is configured to elastically abut against the location of the abutment portion G (i.e., the center in the left-right direction of the payout reel body portion c1), which is set to maintain the appropriate posture of the payout reel C.
[0071] The elastic engagement portion Q is disposed at a position displaced in the direction of the axis cn of the first support shaft j1 so as to be located closer to the center of the payout reel body c1 in the left-right direction than the payout gear body m1.
[0072] The elastic engagement portion Q is bridged between adjacent base portions U. The elastic engagement portion Q is provided at a location facing the through hole I. The elastic engagement portion Q includes an elastic engagement portion main body q1 and an abutting portion q2 that is protruded from the elastic engagement portion main body q1 and abuts against the abutted portion G of the payout reel C.
[0073] The elastic engagement portion main body q1 has both ends connected to the base portion U. A protruding portion q11 that protrudes in the opposite direction from the payout gear main body m1 is provided at the center of the elastic engagement portion main body q1. A contact portion q2 that constitutes the slip clutch S mechanism is provided on the outer surface side of the protruding portion q11.
[0074] <Take-up gear N> The winding gear N has a plurality of teeth ha on its outer periphery that mesh with the payout gear M. The winding gear N is integrally formed on the winding reel D with its axis cn aligned with the winding reel D.
[0075] <Slip clutch S> The slip clutch S allows relative rotation (slippage) between the payout gear M and the payout reel C when tension in the transfer tape T exceeds a certain level, in order to optimize the degree of tension in the transfer tape T stretched between the payout reel C and the take-up reel D.
[0076] The slip clutch S comprises an elastic engagement portion Q provided on the payout gear M and an abutment portion G provided on the payout reel C against which the elastic engagement portion Q of the payout gear M elastically abuts.
[0077] The elastic engagement portion Q has both ends supported by the base portion U, and has adjacent through holes I. The abutting portion q2 protruding from the elastic engagement portion Q elastically contacts the abutted portion G by utilizing the elastic deformation of the member.
[0078] Next, the operation of the slip clutch S in the transfer tool of this embodiment will be described.
[0079] In the transfer tool, when the transfer tape T, which is backed by the transfer roller b4 of the transfer head B, is moved while contacting the surface to be transferred, the transfer tape T is sequentially paid out from the payout reel C. At the same time, the rotational force of the payout reel C generated by the movement of the transfer tape T is transmitted to the take-up reel D by the reel interlocking mechanism E, so that the transfer tape T is taken up by the take-up reel D.
[0080] The rotational force of the payout reel C is transmitted to the payout gear M via the slip clutch S. Furthermore, the rotational force of the payout reel C is transmitted to the take-up gear N meshed with the pay-out gear M and to the take-up reel D formed integrally with the take-up gear N. The take-up reel D then receives the rotational force and winds up the transfer tape T.
[0081] As the remaining amount of transfer tape T wound around the supply reel C decreases and the amount of transfer tape T wound around the take-up reel D increases, the rotation speed of the supply reel C increases and the rotation speed of the take-up reel D also increases. As a result, the tension, or degree of tension, of the transfer tape T between the take-up reel D and the supply reel C gradually increases. In addition, the rotational force transmitted from the supply reel C to the pay-out gear M also increases in proportion to the tension of the transfer tape T.
[0082] When this rotational force increases above a predetermined level, the rotational force of the payout reel C becomes greater than the frictional force between the payout reel C and the payout gear M, causing the payout reel C to slide in the rotational direction relative to the payout gear M. In other words, the payout reel C rotates faster in the rotational direction than the payout gear M.
[0083] In this embodiment, the abutment portion q2 of the elastic engagement portion Q provided on the loop structure portion m3 of the payout gear M elastically contacts the abutment portion G, which is the inner surface of the payout reel main body portion c1 of the payout reel C, so that the specified sliding function can be suitably exerted when necessary.
[0084] In addition, the elastic engagement portion Q, which can work in cooperation with the payout reel C to function as a slip clutch S, is provided in the loop structure portion m3 of the payout gear M, but the detachment prevention portion m2, which can function to prevent the payout reel C from coming off the payout gear M, is provided at a position closer to the axis cn than the loop structure portion m3 of the payout gear M (i.e., at a position different from the loop structure portion m3).
[0085] Therefore, with the configuration of the slip clutch S in this embodiment, the pressing force applied by the elastic engaging portion Q to the abutted portion G is unlikely to fluctuate during the assembly process, etc., and can be set to a stable value. In other words, with the slip clutch S in this embodiment, resin friction can be easily stabilized, allowing for favorable operation.
[0086] As described above in detail, the transfer tool according to this embodiment is configured so that the transfer tape T is fed from the feeding reel C, passes through the transfer head B, and is taken up by the take-up reel D.
[0087] The transfer device is equipped with a reel linkage mechanism E that links the rotation of the payout reel C and the take-up reel D, and a slip clutch S that constitutes the reel linkage mechanism E and causes slippage between the payout gear M, which is a first rotating member that rotates around the first support axis j1, which is a common axis, and the payout reel C, which is a second rotating member, thereby optimizing the degree of tension of the transfer tape T.
[0088] The slip clutch S comprises an elastic engagement portion Q provided on the payout gear M, and an abutment portion G provided on the payout reel fitted onto the payout gear M and against which the elastic engagement portion Q elastically abuts. The payout gear M is provided with a loop structure portion m3 that includes the elastic engagement portion Q and is continuous in a loop shape surrounding the axis cn.
[0089] Therefore, in this embodiment, it is possible to provide a transfer tool in which the payout gear M and the payout reel C, which constitute the slip clutch S, can be easily assembled.
[0090] In other words, the payout gear M is provided with a loop structure portion m3 that includes an elastic engagement portion Q and is continuous in a loop shape surrounding the axis cn, and by fitting a payout reel C that has an abutment portion G onto this loop structure portion m3, a slip clutch S that can perform the desired function can be easily constructed.
[0091] In other words, because the loop structure m3 is fitted inside the payout reel C, the biasing force of the elastic engagement portion Q, which may be generated by elastic deformation of the member, is generated stably. Therefore, with this embodiment, it is possible to effectively prevent the occurrence of variations in the function of the slip clutch S from product to product.
[0092] The payout gear M, which is the first rotating member, is provided at a location different from the loop structure portion m3 and includes a separation prevention portion m2 that can prevent the payout reel C from separating.
[0093] Therefore, even if the separation prevention portion m2 is deformed when attaching the payout reel C to the payout gear M, the function of the slip clutch S is unlikely to be affected.
[0094] A plurality of, that is, three, elastic engagement portions Q are provided in the loop structure portion m3.
[0095] Therefore, the three elastic engagement portions Q can bias the payout reel C in a balanced manner.
[0096] The payout gear M is provided with a through hole I adjacent thereto, which allows the elastic engagement portion Q to elastically deform in the radial direction.
[0097] Therefore, the elastic engagement portion Q is flexibly elastically deformed in the radial direction by the adjacent through holes I.
[0098] The loop structure m3 has a substantially triangular shape, and the loop structure m3 has elastic engagement portions Q disposed at three locations farthest from the axis cn.
[0099] Therefore, the three elastic engagement portions Q can bias the payout reel C in a balanced manner.
[0100] The elastic engaging portion Q includes an elastic engaging portion main body q1 and a contact portion q2 that is provided in a protruding manner on the elastic engaging portion main body q1 and that contacts the contacted portion G.
[0101] Therefore, the elastic engaging portion Q can be elastically deformed suitably by the elastic engaging portion main body q1. Furthermore, the portion of the elastic engaging portion Q that comes into contact with the abutted portion G is limited to the abutting portion q2, so that the slip clutch S can be set suitably.
[0102] The separation restricting portion m2 is provided at a position closer to the first support shaft j1, which is the common shaft, than the elastic engaging portion Q is.
[0103] Therefore, the separation restricting portion m2 can suitably prevent the payout reel C from coming off.
[0104] The payout gear M comprises a payout gear main body m1 having a plurality of teeth ha arranged in a row on its annular outer peripheral edge, and an elastic engagement portion Q arranged at a position displaced in the direction of the axis cn of the common shaft from the payout gear main body m1.
[0105] As a result, the elastic engagement portion Q can abut against the abutment portion G arranged at a suitable location on the payout reel C, and the payout reel C fitted onto the payout gear M is stably supported relative to the payout gear M.
[0106] The present invention is not limited to the above-described embodiment.
[0107] The transfer tool may be any tool that transfers the transfer material attached to the transfer tape to the transfer target. In other words, the transfer material is not limited to the glue shown in this embodiment, but may also be, for example, a thin film correction agent or a decorative decoration (decorative tape).
[0108] The first and second rotating members that rotate around a common axis are not limited to those shown in this embodiment.
[0109] The first rotating member may be a payout reel, and the second rotating member may be a payout gear.
[0110] Furthermore, one of the first rotating member and the second rotating member may be a take-up gear, and the other may be a take-up reel.
[0111] The first rotating member and the second rotating member may be separate members from the gear and reel that are interposed between the gear and reel that rotate around a common axis, for example, cylindrical members known as core members.
[0112] It is preferable that the first rotating member has a gear function, and it is preferable that the second rotating member has a function of winding and holding the transfer tape.
[0113] The position restricting portion may have any configuration as long as it is configured to position the second rotating member relative to the first rotating member.
[0114] The transfer head is not limited to the one shown in this embodiment as long as it can perform the function of pressing the transfer tape against the transfer target surface. Other transfer heads include, for example, those in which the tip of a plate-like member serves as a pressing part for pressing the transfer tape against the transfer target surface.
[0115] The transfer tool is not limited to a disposable type that cannot be used after the transfer tape runs out, but may be a refillable type that uses a refill that is a replacement part that holds the transfer material.
[0116] The reel interlocking mechanism can be modified in various ways without departing from the spirit of the present invention, as long as it can interlock the supply reel and the take-up reel. For example, it may be a mechanism in which one or more intermediate gears are interposed between the supply gear and the take-up gear.
[0117] Furthermore, the specific configuration of each part is not limited to the above embodiment, and various modifications are possible within the scope of the present invention. [Explanation of symbols]
