Description

Printing type coating film transfer tool

Technical Field

The present invention relates to a printing type coating film transfer tool for transferring a coating film from a transfer belt to a transfer target surface.

Background

Conventionally, as such a transfer tool, the following are known: the transfer printing device comprises a supply reel and a take-up reel, wherein the supply reel and the take-up reel are respectively arranged in a shell of a cylinder body or a shaft cylinder in a freely rotating way and are used for winding a transfer printing belt after use; a pressing bar pressing the surface of the transfer belt; and a slider (slider) movably disposed in the case and held by elasticity of a spring member (spring or hairspring), and configured to engage a winding pawl provided in the slider with a gear (gear) provided coaxially with the winding reel only in a winding direction of the transfer belt (see, for example, patent document 1).

Patent document 1 discloses a print type configuration as follows: a groove portion for movably fitting a locking pin provided in a shaft tube is provided in a slider which is held in the shaft tube constituting a housing so as to be freely inserted and removed by the elasticity of a spring and a hairspring and has an opening at the tip end, and a pressure rod is inserted and removed from the opening at the tip end of the slider in accordance with the insertion and removal of the slider, whereby the pressure rod is pressed against the back surface of a transfer belt to perform transfer. The transfer belt is tensioned by 2 guide pins provided on the opening side of the slider.

In the configuration described inpatent document 1, since the supply reel and the take-up reel are rotatable, the rotation of the supply reel and the take-up reel is restricted by providing a reverse rotation preventing pawl in each of gears provided coaxially with the supply reel and the take-up reel.

Problems to be solved by the invention

However, in the structure described inpatent document 1, the guide pin that applies tension to the transfer belt is also pushed in at the time of transfer. At this time, the transfer belt may be loosened because winding cannot be performed. Further, there is also a fear that the transfer belt is undesirably pulled out due to a peeling force when the coating film is peeled off from the transfer belt.

Further, since the number of components is increased, the size of the transfer tool itself is increased, and the degree of freedom in design may be reduced, because the reverse rotation preventing mechanism needs to be provided at two positions in addition to the plurality of spring members.

The present invention has been made in view of the above circumstances, and provides a printing type coating film transfer tool capable of preventing the transfer belt from loosening during transfer, reducing the number of components, reducing the size, and improving the degree of freedom in design.

Further, as shown in the schematic diagram of fig. 15 c, since theratchet claw 34 is formed in a substantially triangular shape in cross section having theinclined surface 34a rising toward the tip end, when the take-up reel (spool) 30 rotates in the take-up direction (+ R), theplanar tooth portion 18 is not disturbed, and when the take-up reel (spool) 30 rotates in the opposite direction (-R), theratchet claw 34 engages with theplanar tooth portion 18 to prevent the reverse rotation of the take-up reel (spool) 30.

According to the reverse rotation prevention mechanism configured as described above, the following can be prevented: when theslide member 40 moves outward of thecase 10 by the elastic force of thespring portion 43, the take-up reel (spool) 30 rotates in the reverse direction, and thewound transfer belt 1 slacks.

In the above embodiment, the reverse rotation preventing mechanism is provided between the take-up reel (spool) 30 and the 2 nd take-upreel support shaft 15b provided so as to protrude from theupper case half 11, but the same effect can be obtained by providing the reverse rotation preventing mechanism between the take-up reel (spool) 30 and the 1 st take-upreel support shaft 15a provided so as to protrude from thelower case half 12.

Thelid 50 is formed of a synthetic resin member such as Polystyrene (PS) or ABS resin, and is formed in a bottomed cylindrical shape having a substantially rectangular cross section, which is fitted in theopening 10a of thecase 10. In this case, a plurality of (4)ribs 51 that abut against the end surface of thecase 10 to secure the storage space of theframe 41 are provided at the corners of the inner surface of thecover 50, and a plurality of (4)auxiliary ribs 52 having a rising slope from the opening end of thecover 50 to the bottom are provided at the centers of the sides between theribs 51.

According to thecover 50 formed as described above, even when thecover 50 is slightly deflected when thecover 50 is fitted to thecase 10, thecover 50 can be easily fitted, and the safety of theframe portion 41 protruding from thecase 10 can be protected by thecover 50.

In the coating film transfer tool of the embodiment configured as described above, thetransfer belt 1 having a width of 6.0mm and a length of 3.5m is wound around the take-out reel 20, and when the area of the transfer surface (print surface) is set to 6.0mm × 6.0mm, at least 500 transfers (prints) can be performed.

By using thetransfer belt 1 having the above dimensions, the overall dimensions of the coating film transfer tool can be set to 23.0mm × 23.0mm × 64.8mm, and the overall size can be reduced. Therefore, for example, as shown in fig. 16, the coating film transfer tool can be housed in apen case 62 that houses awriting tool 60 such as a pencil and aneraser 61. Alternatively, the coating film transfer tool may be housed in an office product housing tray provided in a drawer of the desk.

Then, in the case of using the coating film transfer tool configured as described above, first, thetransfer belt 1 pulled out from the pull-out reel 20 is set in a state of being wound around the take-up reel (reel) 30 in a state of being in contact with thepressing surface 13a of thetransfer pressing portion 13 and the adhesive 3 wound around the surface of thetransfer belt 1 of the pull-out reel 20.

In this state, when the user holds thecasing 10 with his hand and presses theframe portion 41 of theslide member 40 against the elastic force of thespring portion 43 against thetransfer target surface 4, thetransfer pressing portion 13 pressing the back surface of thetransfer belt 1 is relatively projected to the outside of theslide member 40 while theslide member 40 moves to the inside of thecasing 10, and the adhesive 3 (coating film) present corresponding to thepressing surface 13a of thetransfer pressing portion 13 is transferred to thetransfer target surface 4.

When theslide member 40 moves to the inside of thehousing 10, if therack gear 44 meshing with the windinggear 33 coaxial with the windingreel 30 moves to the bottom side of thehousing 10 and rotates the windingreel 30 in the winding direction (clockwise in fig. 4 a) together with the windinggear 33, the take-out reel 20 rotates in the take-out direction of the transfer belt 1 (counterclockwise in fig. 4 a) to take out thetransfer belt 1, and the transfer belt 1 (base material 2) used in the previous transfer (printing) is wound up, and thetransfer belt 1 having the adhesive 3 (coating film) moves to thepressing surface 13a of thetransfer pressing portion 13.

When the transfer tool is lifted up after the transfer of the adhesive 3 (coating film), theslide member 40 moves to the outside of thehousing 10 by the elastic force of thespring portion 43 to prepare for the next transfer (printing).

According to the coating film transfer tool of the embodiment configured as described above, thetransfer belt 1 drawn out from the take-out reel 20 is wound around the take-up reel (reel) 30 in a state in which thetransfer belt 1 is in contact with the adhesive 3 on the surface of thetransfer belt 1, and thereby the amount of thetransfer belt 1 drawn out from the take-out reel 20 rotated by friction caused by contact between the adhesive 3 (coating film) wound around the surface of thetransfer belt 1 on the take-out reel 20 and the used transfer belt, i.e., thebase material 2, can be controlled. Further, thetransfer belt 1 is not drawn out from the take-out reel 20 unless it is wound around the take-up reel (spool) 30, and therefore, thetransfer belt 1 can be prevented from being loosened.

Further, since theframe portion 41, the slidingportion 42, thespring portion 43, and therack gear 44 are integrally formed in the slidingmember 40, the number of components can be reduced, the size can be reduced, and the degree of freedom in design can be improved.

Further, since the windinggear 33 is provided on the circumferential surface of the axial end portion of therotating shaft 31 of the winding reel (spool) 30 and therack gear 44 is provided on the side surface of the plate-like projectingpiece 42g that is provided at the tip end of the slidingportion 42 so as to linearly extend and be elastically deformable, the engagement between the windinggear 33 and therack gear 44 can be ensured, and the space occupied by the windinggear 33 and therack gear 44 can be reduced.

Further, since the transfer position of the coating film can be confirmed through the window holes 42a for confirming the position provided on the frame side in theframe 41 formed in the cross shape and theslide portion 42 linearly connected to one side of theframe 41, the transfer (printing) of the coating film can be easily performed, and the transfer position can be accurately made.

Even if thetransfer belt 1 wound around the take-out reel 20 is slightly misaligned, the transfer belt can be corrected by the pair ofguide pieces 13d and 13e, and the used transfer belt (base material 2) can be wound around the take-up reel (spool) 30 without being displaced in the width direction, so that the coating film can be further easily transferred (printed).

Further, when theslide member 40 moves to the outside of thecase 10 by the elastic force of thespring portion 43, the take-up reel (spool) 30 is prevented from rotating in the reverse direction and thewound transfer belt 1 is prevented from being loosened. In this case, the reverse rotation prevention mechanism includes: aplanar tooth portion 18 provided on a circle concentric with the center of the 2 nd take-upreel support shaft 15b in theupper case half 11; and a plurality ofratchet pawls 34 that are provided at the tip end of therotating shaft 31 of the take-up reel (spool) 30 so as to project in an arc shape in the circumferential direction of the rotating shaft and are elastically deformable, and theplanar tooth portion 18 and theratchet pawls 34 are formed so as to be engageable when the take-up reel (spool) 30 is rotated in the direction opposite to the take-up direction, whereby the reverse rotation preventing mechanism can be easily assembled.

Further, even when thecover 50 is slightly deflected when thecover 50 is fitted to thecase 10, thecover 50 can be easily fitted, and the safety of theframe portion 41 protruding from thecase 10 can be protected by thecover 50.
