Description

Coating film transfer machine

Technical Field

The present invention relates to a coating film transfer tool, and more particularly to a coating film transfer tool in which a transfer head for pressing a transfer belt against a transfer target to transfer a coating film on the surface of the transfer belt to a transfer target surface is loaded in a housing so that the transfer head can be moved in and out.

Background

Various kinds of coating film transfer devices for attaching an adhesive or correcting misprints have been proposed. The structure of these coating film transfer tools includes: a supply reel equipped with a supply spool that winds an unused transfer belt in a housing; a take-up reel to which a used transfer belt take-up spool is attached after being drawn out from a supply spool for use; and a reel interlocking device for interlocking the supply reel and the take-up reel. In general, a sliding mechanism is formed on the shaft of the supply reel, and the sliding mechanism absorbs the difference in the transfer belt transfer amounts between the supply reel and the take-up reel, thereby keeping the transfer belt in a constant taut state. Further, as the transfer belt used here, a coating film which can be easily peeled off from the surface of a resin belt or a paper belt which is a transfer medium is provided on the surface.

These coating film transfer devices project a transfer head from a housing, suspend a transfer belt on the transfer head, and move the housing while pressing the transfer head in a state where the transfer head is in close contact with a transfer target surface such as a paper surface, thereby transferring a coating film of the transfer belt to the transfer target surface such as a paper sheet. At the same time, the transfer belt is sequentially paid out from the spool of the supply reel, and the used transfer belt is wound up by the spool of the take-up reel.

In these coating film transfer devices, there is a possibility that the transfer belt may fail when it is bent, and therefore, it is often necessary to make the transfer belt have a tension of a predetermined value or more. Therefore, the number of rotations of the take-up spool is adjusted to be larger than the number of rotations of the supply spool. However, when the coating film transfer machine is continuously used, the amount of the transfer belt wound around the supply spool is decreased, and the amount of the substrate tape wound around the winding spool is increased, so that the number of the wound substrate tapes per rotation of the winding spool is increased, the slippage of the sliding mechanism is increased, the transfer load required for the transfer is increased, and the transfer becomes difficult. Therefore, in order to prevent the entire rotation of the supply spool of the coating film transfer device from being transmitted to the take-up spool, it is necessary to appropriately idle the supply spool.

In japanese patent application laid-open No. 2002-283795, a technique is proposed in which a supply spool and a take-up spool are connected by a rubber tape, and a shaft of the take-up spool is moved. This proposal suggests that when the transfer head is pressed against the transfer object, the shaft of the take-up spool moves in the direction of the supply spool, and the distance between the spools decreases and the tension of the rubber tape decreases, so that the slip torque acting between the rubber tape and the shafts of the spools decreases, and the spools can slip under a small load.

Further, japanese patent laying-open No. 5-178525 proposes a technique in which a rubber slip ring is fitted between a gear rotated by a supply spool and the supply spool, thereby allowing the supply spool to slip relative to the gear.

As described above, when the transfer is performed by the coating film transfer device, the user needs to press the coating film transfer device against the transfer surface in the form of a transfer head with a load required for transferring the transfer film of the transfer belt to the transfer target. However, in the conventional coating film transfer device, since the number of idle running of the supply bobbin immediately after the use is increased as compared with the case of immediately starting the use of the transfer belt, the load required for pulling out the transfer belt is increased, and the load applied to the upper surface of the transfer head is also increased. However, it is difficult for the user to adjust the external force applied to the upper surface of the transfer head with the fingers, and there is a problem that the probability of transfer failure increases when the application film transfer unit is continuously used.

In addition, when the transfer head 24 is pressed and slid in a state of being transferred, the coating film transfer section 2 generates tension in the transfer belt 20 suspended on the transfer head 24, and a new transfer belt 20 is continuously unwound from the supply spool 21, and the supply spool 21 rotates while the transfer belt 20 is continuously unwound, and since the rotation of the supply spool 21 is transmitted to the take-up spool 22 by the transmission device, the take-up spool 22 rotates to take up the used transfer belt 20. Thus, if the transfer head 24 is slid in a state of being pressed against the transfer object, the transfer can be performed at all times.

Further, as shown in fig. 5, the operation control section 3 of the knock mechanism for sliding the coating film transfer section 2 back and forth so that the transfer head 24 can be inserted into and removed from the housing case 4 includes: a knocking member 51 which is operated while being put in and out of the housing case 4 of the transfer head 24, a rotation supporting member 55 which is disposed between the coating film transfer section 2 and the knocking member 51, and a rotating member 61 which is slidably and rotatably disposed inside the rotation supporting member 55.

The striking member 51 is composed of a hollow operation portion 52 having a front end provided with an opening and a rear end formed in a curved shape, and a cylindrical shaft body 53 extending in the axial direction from the rear end portion of the inner peripheral surface of the operation portion 52. The operation portion 52 has two slide protrusions 52a at positions where outer peripheral surfaces of the front end edges face each other, and the front end of the shaft body 53 is formed to protrude further than the front end edge of the operation portion 52. The shaft body 53 has a plurality of inclined portions at its distal end to form a tooth portion 53 a. The diameter of the outer periphery of the operation portion 52 is slightly smaller than a rear opening portion formed at the rear end of the storage case 4, which will be described later. By fitting the slide projection 52a into slide grooves 77a and 77b formed on the rear end side of the storage case 4, which will be described later, the operation portion 52 is not rotatable but slidable in the axial direction in a state where the rear end portion is projected from the rear opening portion of the storage case 4.

The rotation support member 55 is formed of a cylindrical main body 56 having an open front end and a rear end and having a substantially cylindrical shape, and two support arms 58 disposed in the vicinity of the front end of the outer peripheral surface of the cylindrical main body 56. The outer peripheral diameter of the cylindrical body portion 56 is formed smaller than the inner peripheral diameter of the operation portion 52 of the striking member 51, and the shaft body 53 of the striking member 51 can be inserted into the inner space. As shown in fig. 6, three guide groove portions 56a extending in the axial direction are formed at three places at equal intervals in the circumferential direction on the inner peripheral surface of the cylindrical main body portion 56, and the rear ends of the guide groove portions 56a include first locking portions 57 a. In addition, the portions sandwiched between the adjacent guide groove portions 56a are formed with: a first inclined portion 56b inclined rearward from the front end of the guide groove portion 56a and having a second locking portion 57b, a sliding wall portion 56c extending forward in the axial direction from the rear end of the first inclined portion 56b, and a second inclined portion 56d inclined rearward from the front end of the sliding wall portion 56c and connected to the guide groove portion 56 a.

Further, the two support arms 58 are formed at positions where the outer peripheral surfaces of the distal end sides of the cylindrical body portion 56 face each other, and as shown in fig. 7 and 8: a shoulder portion 58c protruding substantially perpendicularly to the outer peripheral surface of the cylindrical body portion 56, an arm base portion 58b connected to the shoulder portion 58c and extending forward in the axial direction, and a slope portion 58a connected to the arm base portion 58b and having a tip end side inclined outward. Therefore, when a pressing force is applied to the distal end portion of the support arm 58 from the outside, the support arm 58 can be bent in a direction in which the distal end portions approach each other. The support arm 58 is formed such that the arm base 58b and the inclined portion 58a are in contact with sliding support portions 75a, 75b formed in the housing case 4 described later, the cylindrical body portion 56 is supported by the concave portions 74a, 74b of the rear stop portions 73a, 73b of the housing case 4, the arm base 58b and the inclined portion 58a of the support arm 58 are disposed inside the housing case 4 in a state of being in contact with the sliding support portions 75a, 75b, and the shaft body 53 of the striking member 51 is inserted into the opening portion on the rear end side of the cylindrical body portion 56.

The rotating member 61 is formed of a large diameter portion 62 having a substantially cylindrical shape with an opening at the front end side, and a small diameter portion 63 provided behind the large diameter portion 62 via a tapered portion which is reduced in diameter from the rear end edge of the large diameter portion 62. The large diameter portion 62 includes linear protrusions 64 on the outer peripheral surface thereof, which are fitted in the three guide groove portions 56a of the rotation support member 65. The large diameter portion 62 has an outer diameter capable of being accommodated inside the rotary support member 55, and an inner diameter thereof is formed slightly larger than an outer diameter of the locking post 26d provided protruding on the first transfer section housing 26 of the application film transfer section 2, whereby the locking post 26d of the application film transfer section 2 can be inserted. The small diameter portion 63 can be inserted into the shaft body 53 by forming the outer diameter slightly smaller than the inner diameter of the shaft body 53 of the striking member 51. The linear protrusion 64 is formed between the front end of the small diameter portion 63 and the vicinity of the front end of the large diameter portion 62, and the rear end portion is formed to have an inclined surface in which the inclination of the first inclined portion 56b and the inclination of the second inclined portion 56d formed on the inner peripheral surface of the rotation support member 55 are kept substantially the same.

The housing case 4 in which the coating film transfer section 2, the knocking member 51, the rotation support member 55, and the rotation member 61 are loaded is configured by a first housing case 4a and a second housing case 4b as shown in fig. 9, and forms a front and rear elongated housing case 4 which can be handled with one hand as a whole.

The first storage case 4a is formed with a side plate portion having a front end and a rear end which are narrow when viewed from the front, and a peripheral edge portion which is substantially orthogonal to the side plate portion from both side edges of the side plate portion, and has a cross section in a substantially コ shape. The front portion 71a as a string step portion is formed in the vicinity of the front end of the inner peripheral surface of the side plate portion so as to extend in the width direction of the side plate portion, small projections are provided at two places on the rear side surface of the front portion 71a, and a locking portion 72a for locking the locking member 43 disposed on the coating film transfer portion 2 is formed at approximately the center.

Further, a rear stopper 73a having a height slightly shorter than the width dimension of the peripheral edge portion is formed in the vicinity of the rear end of the inner peripheral surface of the side plate portion so as to extend in the width direction of the side plate portion, and a recess 74a for disposing the rotation support member 55 is formed by cutting the side edge of the rear stopper 73a into an arc shape substantially conforming to the outer peripheral surface of the rotation support member 55 at substantially the center thereof. From the front side surface of the rear stopper 73a on the outer side of both sides of the recess 74a, a holding portion 76a is formed, the front end side of which is inclined toward the peripheral edge portion and the rear end side of which is along the axial direction of the first storage case 4a, and is positioned at a position where both sides are symmetrical about the central axis of the storage case, and is formed in a shape of almost ハ in front view. Further, on the outer surface of the holding portion 76a, slide supporting portions 75a are provided in parallel with the holding portion 76a, and the slide supporting portions 75a are formed to protrude from the holding portion 76 a. Further, a slide groove 77a into which the slide projection 52a of the striking member 51 is fitted is formed at a substantially central position of the side plate portion by two linear segment portions extending in the axial direction from the rear side surface of the rear portion 73a and having rear end portions connected to each other. Further, a winding hole 78 is formed near the center of the side plate portion, and the winding hole 78 is used to operate the winding auxiliary portion 39 of the coating film transfer portion 2 from the outside of the storage case 4 to adjust the tension state of the transfer belt.

The second housing case 4b is a member facing the first housing case 4a, and is formed with a side plate portion having a front end and a rear end which are narrowed when viewed from the front, and a peripheral edge portion substantially orthogonal to the side plate portion from both side edges of the side plate portion, and has a cross section of a substantially コ shape. The front portion 71b as a string segment portion extends in the width direction of the side plate portion and is formed near the front end of the inner peripheral surface of the side plate portion, small protrusions are provided at two places on the rear side surface of the front portion 71b, and a locking portion 72b for locking the locking member 43 disposed on the coating film transfer portion 2 is formed at a substantially central position.

Further, a rear stopper portion 73b is formed in the vicinity of the rear end of the inner peripheral surface of the side plate portion so as to extend in the width direction of the side plate portion and to be slightly shorter than the width dimension of the peripheral edge portion, and the side edge of the rear stopper portion 73b is cut into an arc shape substantially conforming to the outer peripheral surface of the rotation support member 55 at substantially the center portion thereof, so as to form a recess 74b for disposing the rotation support member 55. From the front side surface of the rear stopper 73b on the outer sides of both sides of the recess 74b, a holding portion 76b is formed, the front end side of which is inclined toward the peripheral edge portion and the rear end side of which is along the axial direction of the second storage case 4b, and is positioned with the central axis of the storage case as the axis of symmetry, and is formed in a shape of approximately ハ in front view. Further, on the outer surface of the holding portion 76b, a slide support portion 75b is provided in parallel with the holding portion 76b, and the slide support portion 75b is formed to protrude from the holding portion 76 a. Therefore, when the first storage case 4a and the second storage case 4b are integrated, a step portion is formed which can support the support arm 58 of the rotation support member 55 by the holding portions 76a and 76b and the sliding support portions 75a and 75 b. Further, a slide groove 77b into which the slide projection 52a of the striking member 51 is fitted is formed at a substantially central position of the side plate portion by two linear segment portions extending in the axial direction from the rear side surface of the rear portion 73b and having rear end portions connected to each other.

The first storage case 4a and the second storage case 4b have a concave portion or a convex portion formed so as to be able to fit together with the edge portions of the peripheral edge portions, and at the same time, have locking projections or locking receiving portions formed in the vicinity of the front end and the vicinity of the rear end, and have a coupling shaft portion 79a protruding from the peripheral edge portion from the inner peripheral surface of one of the side plate portions of the first storage case 4a or the second storage case 4b, and a bearing hole 79b formed in the inner peripheral surface of the side plate portion of the other of the cases so as to fit into the coupling shaft portion 79 a. Therefore, since the first accommodation case 4a and the second accommodation case 4b are connected to each other to form a hollow shape, a front opening portion is formed at the front end and a rear opening portion is formed at the rear end.

As shown in fig. 5 and 7, the coating film transfer section 2, the knocking member 51, the rotation support member 55, and the rotation member 61 are in a state where the locking portion 26d of the coating film transfer section 2 is inserted into the rotation member 61, the linear protrusion 64 is arranged at the position of the guide groove 56a when the rotation member 61 is fitted into the rotation support member 55, the shaft body 53 of the knocking member 51 is inserted from the opening on the rear end side of the rotation support member 55, the tooth portion 53a of the shaft body 53 and the linear protrusion 64 of the rotation member 61 are engaged with each other, and the respective members are arranged on the same shaft. The rotary support member 55 is supported by the recesses 74a and 74b of the rear portions 73a and 73b of the housing case 4 and the slide support portions 75a and 75b, and is loaded into the housing case 4 such that the locking claw 43a of the locking member 43 provided in the coating film transfer unit 2 engages with the locking portions 72a and 72b formed in the front portions 71a and 71b of the housing case 4, and the slide projection 52a of the striking member 51 engages with the slide grooves 77a and 77b formed behind the rear portions 73a and 73b of the housing case 4. At this time, the pressing spring 42 provided in the coating film transfer section 2 is extended to bias the coating film transfer section 2 rearward, the rotary member 61 is positioned on the rear end side of the rotary support member 55 to move the coating film transfer section 2 rearward, and the transfer head 24 is accommodated in the accommodation case 4.

Next, the operation of the coating film transfer tool 1 of the present invention will be described.

As shown in fig. 7, in a state where the transfer head 24 is retracted and stored in the storage case 4, as shown in fig. 6(a), the string protrusions 64 of the rotary member 61 are fitted into the guide groove portions 56a of the rotary support member 55, and the rear end portions of the string protrusions 64 are locked to the first locking portions 57a of the guide groove portions 56 a.

When the striking member 51 is struck from behind, the rear end portion of the linear projection 64 is pressed by the shaft body 53 of the striking member 51 against the pressing spring 42, and the linear projection 64 slides in the forward direction to guide the groove portion 56 a. At this time, the coating film transfer section 2 locked to the rotary member 61 by the locking column 26d also moves forward at the same time. If the rear end portion of the linear protrusion 64 slides beyond the front end portion of the slide guide groove portion 56a, as shown in fig. 6(b), the inclined surface of the rear end of the linear protrusion 64 comes into contact with the inclined portion of the tooth portion 53a of the front end portion of the shaft body 53, the rotary member 61 is biased rearward by the pressing spring 42, and the linear protrusion 64 moves rearward while rotating along the inclination of the tooth portion 53a because the striking member 51 is fitted in the housing case 4 and cannot rotate. When the inclined surface of the linear projection 64 of the rotating member 61 that rotates comes into contact with the first inclined portion 56b, the linear projection 64 slides backward along the inclination of the first inclined portion 56b, and is locked to the second locking portion 57b as shown in fig. 6 (c). Thus, as shown in fig. 8, the rotary member 61 is fixed in a state of protruding from the rotary support member 55, and the coating film transfer section 2 engaged with the rotary member 61 is also fixed at the advanced position, so that the transfer head 24 protrudes from the housing case 4. At this time, the locking member 43 provided in the coating film transfer section 2 is locked to the housing case 4, and the pressing spring 42 is compressed.

Further, if the striking member 51 is struck again, the linear projection 64 of the rotary member 61 locked to the second locking portion 57b is pushed by the tooth portion 53a of the striking member 51 and slides in the forward direction along the sliding wall portion 56c against the pressing spring 42. However, when the slide plate advances beyond the front end of the slide wall portion 56c, the guide groove portion 56a connected to the second inclined portion 56d is fitted into and locked to the first locking portion 57a while sliding rearward along the inclination of the second inclined portion 56d due to the biasing force exerted in the rearward direction by the pressure spring 42. When the rotary member 61 slides to the rear end position of the rotary support member 55, the application film transfer section 2 is also retracted by the biasing force of the pressing spring 42, and the transfer head 24 is stored in the storage case 4.

Next, the effects of the present invention will be described. Although the coating film transfer tool 1 has an optimum transfer load, in the conventional coating film transfer tool, a load required for pulling out the transfer belt 20 is greatly changed at the time of starting and finishing the use of the product, and it is difficult for a user to feel the optimum transfer load. That is, there are the following problems: when the slip torque between the clutch member 31 and the supply-side gear 32 is made larger in accordance with the timing at which the product is just started to be used, the transfer load at the time of the end of use becomes excessively large, and conversely, when the slip torque is made smaller in accordance with the timing at the end of use, the transfer load at the time of the start of use becomes excessively small.

However, since the coating film transfer device 1 of the present embodiment includes the load adjusting means for applying a load to the rotation of the supply spool 21, even if the slip torque between the clutch member 31 and the supply-side gear 32 is reduced, the transfer load immediately before the start of use is not excessively reduced by increasing the load of the load adjusting means, and even if the transfer load is not substantially changed due to the small slip torque between the clutch member 31 and the supply-side gear 32 at the end of use, the transfer load can be maintained at a constant value at the start and end of use. Therefore, the user can always apply a certain transfer load to perform the transfer. Thus, it is possible to prevent transfer failure due to a change in transfer load, and to provide the coating film transfer tool 1 capable of always performing stable transfer.

Further, the load adjusting device may have a different configuration from the above-described embodiment. For example, as shown in fig. 10, the load adjusting device may be configured by a relief edge 21d formed to protrude outward from the upper end of the supply bobbin 21, and a relief arm 27t formed on the second transfer section casing 27 to be locked to the relief edge 21d of the supply bobbin 21. Even in the case of such a configuration, by pressing the relief arm 27t of the second transfer section casing 27 against the relief edge 21d of the supply spool 21, a slip torque due to a frictional force is generated between the relief arm 27t and the relief edge 21d of the supply spool 21, and a load can be applied to the rotation of the supply spool 21.

As shown in fig. 11, the load adjusting device may be constituted by an inner cylinder protrusion 31d formed to protrude inward from a predetermined position of the inner cylinder of the clutch member 31 and a relief groove 26k formed at a position where the inner cylinder protrusion 31d of the holding shaft 26a of the first transfer unit housing 26 is pressed against. Even in the case of such a configuration, when the clutch member 31 is rotated on the outer peripheral edge of the holding shaft 26a by the rotation of the supply spool 21, a slip torque due to a frictional force is generated between the inner cylindrical protruding portion 31d of the clutch member 31 and the relief groove 26k of the holding shaft 26a, and a load can be applied to the rotation of the supply spool 21.

As shown in fig. 12, as the load adjusting device, a stopper member 38 having an elastic arm 38a and a fitting portion 38b fitted to the inner cylinder of the supply spool 21 is disposed between the supply spool 21 and the second transfer section housing 27, the second transfer section housing 27 forms a stopper relief wall 27j to which the elastic arm 38a of the stopper member 38 is pressed, and the stopper member 38 is fitted to the upper end of the supply spool 21 so as to rotate in conjunction with the supply spool 21, whereby the elastic arm 38a of the stopper member 38 can be slidably pressed against the stopper relief wall 27j of the second transfer section housing 27. Even in this case, a load can be applied to the rotation of the supply bobbin 21 because a slip torque due to a frictional force will be generated between the elastic arm 38a of the restrainer member 38 and the restrainer stopper wall 27j of the second transfer section housing 27.

Next, a modified example of the coating film transfer tool will be described. In the above embodiment, although the knock-type coating film transfer tool 1 has been described, the present modification example is constituted only by the coating film transfer section 2.

In the coating film transfer tool according to the present modification, the transfer section accommodating case formed by the first transfer section case and the second transfer section case is formed as an outer case, and the supply bobbin, the take-up bobbin, the transfer head holding member for holding the transfer head, the rotation transmitting device, and the load adjusting device are arranged on the outer case, and the outer case formed by the first transfer section case and the second transfer section case is held and slid in a state where the transfer head is pressed against the transfer object to perform the pressure-sensitive transfer.

In this case, the supply bobbin, the take-up bobbin, the transfer head, the rotation transmitting device, and the load adjusting device have the same configurations as those of the above-described embodiment. Since the retaining member and the pressing spring are not required, the transfer head holding member is constituted only by the mounting portion where the transfer head is mounted. The first transfer section housing and the second transfer section housing are also configured only by the bobbin holding section without requiring a sliding section, and it is sufficient that the transfer head is disposed so as to protrude outward on the tip end side of the bobbin holding section.

Even in such a coating film transfer machine, since the load adjusting means is provided to apply a load to the rotation of the supply bobbin 21, it is possible to form a small slip torque of the rotation transmitting means, and to constantly maintain the transfer load to a certain degree, prevent the transfer failure and the like due to the change in the transfer load.

The present invention is not limited to the above embodiments, and can be freely modified and improved within the scope not exceeding the gist of the present invention.
