Description

The present invention relates to transfer devices for

  adhesive products and, more particularly, to devices of this type which allow the user to transfer an adhesive product while observing the end of a transfer element, from above, with its casing in the coated state, so that the adhesive product can be precisely placed and transferred to a desired location. The present invention also relates to a device for transferring adhesive products which is particularly useful and allows a regular unwinding and transfer of a low adhesion adhesive product, such as a correction tape for correcting letters or the like, a marking tape consisting by a colored thin film to accent letters or the like, as well as other papers allowing adhesive or the like to be applied to a transfer surface

  and repeatedly separated from it.

  Adhesive transfer devices have recently been created which can transfer a correction tape applied to a separable sheet of paper or a transparent colored marking tape on a transfer surface while the tape is unrolled from one end of a case. . These adhesive product transfer devices, unlike traditional type correcting liquids or marker pens, do not require any drying operation. In addition, these devices allow coating to a uniform thickness. In addition, the adhesive product once transferred to the transfer surface can be easily removed without the use of any rubber eraser or the like, so that it

  will not soil the transfer surface.

  Such a device for transferring a correction tape or a marking tape generally has a closed loop structure, in which a roll of correction tape or marking tape is placed in a housing and also a separable sheet of paper, remaining after transfer of the sheet, is wound on a roller provided in the housing and interdependent on the ribbon roll. Some transfer devices are used by pulling them along a transfer surface with their case held vertically above them. Other transfer devices are used by pulling them to the left or right with their casings in the coated state, so that the user can observe the end of a transfer element from above and place accurately and transfer the adhesive product to a desired location. In the above device for transferring a correction tape or a marking tape placed in a case, however, once the separable sheet of paper is broken, the tape can no longer be unwound from the roll of tape, which prohibits transfer. In addition, when the separable sheet of paper is excessively unwound, it is difficult to restore the ribbon to an appropriate state of tension. In addition, as long as the structure of the closed loop is complex, it is impossible to replace a new roll of tape after the tape has been used up completely. Therefore, the device must inevitably be discarded, which is undesirable in view of the current increase in economic trends. In the transfer device, which is used by pulling it to the left or to the right with its case kept lying down, the guide surface of the ribbon of the transfer element is substantially parallel to a lateral surface of the case coming in front of the transfer surface, which constitutes a change in orientation to 90 of the surface of a transfer element of the transfer device which is used with the case held vertically. This means that the adhesive transfer tape, unwound from the roll of tape which is mounted so as to be parallel to the lateral surfaces of the housing, has the surface of its reoriented tape of 90 in contact with two guide pins, which are respectively provided at an inlet and at an outlet of the transfer element. This structure creates a strong mechanical load on the tape, and it is inevitably difficult to feed and drive the adhesive transfer tape and the separable sheet of paper. More specifically, in the transfer device, the force required to unwind the tape depends on the friction force between the adhesive product at the end of the transfer element and the transfer surface. An adhesive product such as a correction tape or a marking tape has low adhesion and provides a low friction force, which makes it difficult to unwind the tape from the tape roll

  compared to a product with strong adhesion.

  The object of the present invention is thus to create an adhesive product transfer device which can be used repeatedly by replacing the tape with adhesive products instead of throwing it away, and which allows the user to transfer the adhesive product while observing the end of a transfer element

  from above with this one in a lying state.

  According to the invention, the adhesive product transfer device comprises a housing in which a roll of tape can rotate, the tape roll being a roll obtained by winding an adhesive product transfer tape having a separable sheet of paper and a adhesive product applied thereto so as to be transferable, and a transfer member projecting outwardly from the housing to guide the adhesive transfer tape unwound from the roll of the tape, presenting the surface of the adhesive product as external surface, the adhesive product being transferred to a transfer surface by pulling the casing in the direction of transfer of adhesive products while the adhesive surface of a portion of the transfer tape of adhesive products located at the free end of the transfer element is kept pushed against the transfer surface, the tape transfer device adhesive products being characterized in that it comprises: a first bevel gear arranged to rotate in the casing and engaging coaxially with the roll of tape, and a second bevel gear coupling with the first bevel gear in such a way that the axes of the two gears are at right angles to each other, the second bevel gear having a smaller number of teeth than that of the first bevel gear and being formed on one side of a roller disposed on the extension of the separable sheet of paper which is left after transfer of the adhesive product and brought back from the transfer element into the housing, the ribbon roller being capable of pulling off the separable sheet of paper which is left after the

transfer of the adhesive product.

  In the drawings, FIGS. 1 and 2 show a first embodiment of a device for transferring adhesive products according to the present invention, and more particularly illustrate the internal structure of the device inside its casing. The reference number 1 thus designates the adhesive product transfer device and the reference number 2 designates its synthetic resin casing, which can be held by the fingers of a user. Reference numeral 3 denotes a roll of adhesive product transfer tape 5, which includes a low adhesion adhesive product (such as a correction tape or a marking tape) applied to an elongated sheet of separable paper 4 so as to be able to to be transferred. The reference number 6 designates a support for the tape roll, which is arranged to rotate in the housing 2 and carries a roll of tape 3 which is detachably attached thereto. The tape roll support 6 has a first bevel gear 7 formed on the outer periphery of its lower part when the housing 2 is lying in the position of use. The reference number 8 designates a feed roller having a second bevel gear 9, which couples with the first bevel gear 7 so that its axis crosses the axis of the latter. Reference numeral 10 designates a beak-shaped transfer member, through which the adhesive transfer tape unwound from the roll of tape 3 is led by presenting the surface of adhesive products outside the outside of the housing. 2. With the surface of adhesive products held pushed against the transfer surface of a sheet of paper or the like, the adhesive product is transferred to the transfer surface by pulling the housing 2 in a direction of transfer of the adhesive product, that is i.e. to the right of Figure 1 in

this embodiment.

  The reference number 11 designates a pinch roller provided on the cover of the housing 2. In the closed state of the housing 2, the pinch roller 11 presses the separable paper sheet 4 against the feed roller 8 to bring out the sheet of separable paper 4. The reference number 12 designates an outlet formed in the housing just

  behind the feed roller 8 and the pinch roller 11.

  It is through the outlet 12 that the separable paper sheet 4 after transfer of the adhesive product is brought to exit towards the outside. Reference number 13 designates a guide pin which is arranged between the roll of tape 3 in the housing 2 and the transfer element 10. The guide pin 13 guides the adhesive transfer tape 5 unwound from the tape roll 3 to the transfer member 10 by changing the orientation of the adhesive transfer tape from 90 relative to the direction of movement of the tape. The guide pin 13 also guides the separable paper sheet 4 after transfer of the adhesive product in contact with an edge of the separable paper sheet 4. The tape roll support 6 and the first bevel gear 7 formed on the outer periphery of the lower part of the tape roll support 6, are parallel to the bottom of the case 2, that is to say to the surface of the case facing the transfer surface. Due to this structure, it is possible to form the adhesive transfer device 1 in such a way that it has a shape suitable for a transfer operation by pulling it to the left of

  Figure 1 with the housing 2 kept lying, that is

  say a thin shape so that it can be held with the thumb and index finger of the user's right hand. The tape roll 3 is an adhesive product transfer tape roll 5, which comprises a low adhesion adhesive product applied to the separable paper sheet 4, which is separable on these two faces. The ribbon roll 3 is detachably engaged with a central pin 6a of the ribbon roll support 6 which has a support surface parallel to the bottom of the housing 2. The housing 2 has a hinge 14 and, when the entire roll of ribbon 3 has been unrolled, the user can submit a

  new roll of ribbon by opening the casing 2.

  The transfer element 10, as shown in Figures and 6, is used to conduct the adhesive transfer tape 5, unwound from the roll of tape 3, towards the outside of the casing 2 for the transfer of the adhesive product to the surface transfer. The transfer element 10 has guide walls provided on the opposite sides of its end portion, which has substantially the same width as the adhesive product transfer tape 5. The transfer element 10 also has a contact surface. tape guide, which is parallel to the bottom of the housing 2. As shown in the figure, the adhesive transfer tape 5 unwound from the tape roll 3 is guided by the lower surface of a guide portion of the transfer 10 and positioning by the latter and, by pulling the housing 2 held by the fingers of the user, towards the user, while pushing the surface of adhesive products from the adhesive product transfer tape 5, brought to the beyond the end of the transfer element, against the transfer surface, the adhesive product is transferred thereto, while the separable sheet of paper 4 after transfer of the adhesive product is again brought around the end of the transfer member 10 and guided along the upper surface of the guide portion of the transfer member 10 in

the housing 2.

  As shown in Figures 3 and 4, the feed roller 8 has edges on the opposite sides of its outer periphery, edges which serve as a guide to prevent the separable sheet of paper from being detached. In order to be able to reliably take out the separable paper sheet, against which the feed roller 8 easily slides, in this embodiment, the outer periphery of the roller, with which the separable paper sheet is in contact, should have a high coefficient of friction. In this embodiment, a rubber belt is wound on the outer periphery of the roller, or else the outer periphery of the roller has a rough surface or a roller similar to that for a bundle of papers. The pinch roller 11 clamps and pulls the separable paper sheet 4 in cooperation with the feed roller 8. In the closed state of the housing 2, the pinch roller 11 which is provided on the cover of the housing 2, thus clamps the sheet separable paper 4 in cooperation with the feed roller 8 and, by opening the housing 2, the sheet

  separable paper 4 is released from its pinched state.

  The first bevel gear 7 of the tape roll holder 6 and the second bevel gear 9 of the feed roller 8 couple with each other in such a way that their axes cross each other as shown in FIG. 1. In this embodiment, the ratio of the teeth between the feed roller 8 and the tape roll support 6 is adjusted so that the speed of rotation of the feed roller 8 is higher than that of the roll support of tape 6. For example, the feed roller 8 makes about two rotations for one revolution of the tape roll support 6. Obviously, the ratio of the teeth is not limited to 2: 1,

  but can be adjusted in any other appropriate way.

  We will now describe a series of operations for transferring adhesive products from the transfer device.

  of adhesive products 1 having the above construction

  above according to the first embodiment of the present invention. First, the end of the transfer member 10 of the adhesive product transfer device 1 is held in contact with the transfer surface of a sheet of paper or the like at an appropriate angle thereto. . Next, the adhesive product transfer device 1 is pulled in the direction of transfer of the adhesive product, that is to the right of FIG. 1, while applying an appropriate pushing force thereto. In this way, the adhesive product at the end of the transfer member 10 is pushed against the transfer surface and transferred thereon, while the adhesive product transfer tape 5 between the support ribbon roll 6 and the transfer member 10 is pulled and unwound. The tape roll support 6 is thus caused to rotate anti-clockwise in FIG. 1, and it causes the feed roller 8 to rotate in the direction of

  clockwise in Figure 2.

  The separable sheet of paper 4 after transfer of the adhesive product is pinched between the feed roller 8 and the pinch roller 11, and is brought, due to the rotation of the feed roller 8, to the outlet 12 provided at the rear of these pebbles. As shown in Figure 2, in its path from the transfer element 10 to the outlet 12, the separable sheet of paper 4 moves in a substantially straight line without being folded up, down, to the left or to the right, or be made to twist. The separable sheet of paper 4 is only in contact on one side thereof with the guide pin 13, and it can be made to come out regularly without constituting a significant mechanical load with respect to its traction by the roller. feed 8. The adhesive product transfer tape 5, unwound from the roll of tape 3, and the separable sheet of paper 4, brought out by the feed roller 8, are obviously of equal length. However, due to the ratio of the teeth indicated above, the feed roller 8 is rotated at twice the speed of the tape roll holder 6, so that the separable sheet of paper 4 receives an appropriate tension around the transfer element 10 while undergoing sliding between the feed roller 8 and the pinch roller 11. The user transferring the adhesive product (that is to say the corrective tape in this embodiment) on the transfer surface, can thus observe the front end of the transfer element, through which the adhesive to be transferred on the transfer surface is brought out from above with the housing 2 to the lying state. The adhesive product can thus be transferred by placing it precisely at the location where the transfer must be made. The separable sheet of paper 4, after transfer of the adhesive product, is outside of its direction of movement relative to the fingers of the user who hold the case 2 of the adhesive product transfer device 1. Although this is not shown , it is possible to provide an appropriate cutting element at the outlet 12 of the housing 2 so that it is possible to easily

  cut the separable sheet of paper 4.

  Figures 7 to 9 show a second embodiment of the adhesive product transfer device according to the present invention. Unlike the first embodiment discussed above, the adhesive transfer device referenced as a whole by 15 has a construction in which the separable sheet of paper, left after transfer of the adhesive product, is wound in the casing. , and in that it is possible to use it again by simply replacing the ribbon cassette by a substitute ribbon cassette 16 containing a roll of ribbon, as shown in FIG. 10, instead of

throw it away.

  FIG. 10 shows the device with the substitution ribbon cassette 16 which has been removed from the housing 17. A frame element 18, which constitutes a base for the substitution ribbon cassette 16, is extended horizontally by a flange 19, which rotatably supports a roll of tape 3. The adhesive transfer tape 5 unwound from the tape roll 3 is guided towards a transfer element 10 by changing, from, the direction of travel of the tape. The transfer element 10 has the same structure as in the first embodiment. The adhesive product transfer tape 5 is brought out of the case 17 by presenting its adhesive surface as an external surface, and the adhesive product is transferred to the paper transfer surface or the like by pulling the case 17 in a direction of transfer of adhesive products by presenting the adhesive surface kept pushed against the transfer surface. The separable sheet of paper 4, left after the transfer of the adhesive product, is wound on a winding roller 22 having a second bevel gear 21, which mates with a first bevel gear 20 having its

  axis at right angles to the axis of the latter.

  The first bevel gear 20 is arranged to rotate in the housing 17, which is articulated by a hinge 23, on the side of the housing facing the transfer surface. The upper part of the first bevel gear 20 is engaged by a friction means 24. Due to the friction means 24, the first bevel gear 20 is caused to rotate at the same time as the ribbon roll 3 when the difference between the acting torque on the ribbon roll 3 and on it is below a predetermined value, and it slides and idles when the difference in torque exceeds the

predetermined value.

  As shown in Figures 11 and 12, the friction means 24 has an engagement shaft 24a extending upward and having raised and recessed surfaces in engagement with raised and recessed surfaces of the inner periphery of the roller. ribbon 3, and it also has a cylinder 24c extending downward and having a gear 24b with fine teeth formed on its internal periphery. The first bevel gear has its upper surface provided with five circumferentially spaced ratchet members 20a. The ratchet elements 20a are formed on the free end of a curved spring element. The gear 24b and the ratchet elements 20a mesh with each other, and constitute a friction means, which has a structure resembling a ratchet mechanism and can be driven relatively in opposite directions. Obviously, it is possible to adopt a structure

  different for the friction medium.

  While the tape roll 3 is unrolled, a length of adhesive transfer tape 5 equal to that of the separable sheet of paper 4 wound on the winding roller 22, with the ratio of the number of teeth between the first and second bevel gears 20 and 21 set to about 2: 1 as in the first embodiment, the winding roller 22 is caused to rotate at a speed twice that of the ribbon roll 3 as in the first embodiment . The transfer of adhesive products to the transfer surface causes the adhesive product transfer tape 5 to unwind, thereby applying a torque to the tape roll 3. This torque is transmitted to the winding roller 22 via the first

  and second bevel gears 20 and 21.

  However, with the rotation of the winding side (that is to say of the winding roller 22) at a speed greater than that of the unwinding side (that is to say of the ribbon roll 3), the tension exerted on the separable paper sheet 4 is gradually reduced. This tension is transmitted via the winding roller 22 and the second and first bevel gears 21 and 20 in the order indicated, thereby increasing the torque as a driving force to cause the rotation of the first bevel gear 20. When this torque is increased excessively, it may be such that it causes a reverse rotation of the tape roll 3 from which the adhesive transfer tape 5 is being unwound, finally bringing the sheet of separable paper 4 to break. To avoid this situation, in this embodiment with an increase in the torque applied to the first bevel gear 20, the ratchet elements 20a of the first bevel gear 20 are separated from the gear 24b of the friction means 24, thereby bringing the first bevel gear 20 to run idle with respect to the ribbon roll 3 and

adjusting the tension.

  In actual operation, by a continuous unwinding of the adhesive product transfer tape 5 from the tape roll 3, the winding roller 22 rotates to start and stop repeatedly the winding of the separable paper sheet, at a high frequency, while ensuring appropriate tension to a portion of the adhesive transfer tape 5 around

transfer element 10.

  In each of the embodiments described below

  above, the adhesive transfer tape has been described in such a way that an adhesive product having a low viscosity such as those used is used.

  for correction tapes and marker tapes.

  However, adhesive products with a higher viscosity can generally be transferred more easily than an adhesive product with a lower viscosity. Obviously, the adhesive product transfer device according to the invention can be used not only with a low viscosity adhesive product but also with a high viscosity adhesive product. As described in the foregoing, in the adhesive transfer device according to the present invention, a first bevel gear is arranged to rotate in the housing and is engaged coaxially with the roll of tape, and a second gear bevel is in coupling with the first bevel gear so that the axes of the two gears are at right angles to each other, the second bevel gear having a smaller number of teeth than that of the first bevel gear and being formed on one side of a roller arranged on the extension of the separable paper sheet which is left after the transfer of the adhesive product and brought back from the transfer element into the housing, the roller being able to pull the separable paper sheet which is left after transfer of the adhesive product. Thus, the user can transfer the adhesive product by observing the end part of the transfer element from above with the case maintained in the lying state. Also, even when the adhesive is weakly adhesive and provides little friction force, such as for a correction tape and a marking tape, the adhesive transfer tape and the separable sheet of paper can be brought out evenly. . In addition, the device can be used repeatedly by replacing the roller.

ribbon instead of throwing it away.

  In addition, the separable sheet of paper which is left after the transfer of the adhesive product is pulled by the roller and a guide in contact with the surface of the roller and is discharged towards the outside of the housing through an outlet provided in its extension behind a feed roller arranged in the housing. The separable sheet of paper can thus be discharged towards the outside of the housing without being collected in the housing. Similarly, the device is of relatively simple construction and can be used in a manner

  repeated by replacing the ribbon roll.

  Additionally, the housing further houses a winding roller for pulling and winding up the separable sheet of paper which is left after the transfer of the adhesive product, and a friction means arranged between the tape roller and the first bevel gear which can rotate by coaxially with it and causing the first bevel gear to be rotated at the same time as the ribbon roll when the torque supplied to the first bevel gear is below a predetermined value while causing the first bevel gear to slip and slip when the applied torque exceeds the predetermined value, thereby bringing the rotation of the winding roller to a speed of rotation greater than the speed of rotation of the tape roller which unwinds the adhesive transfer tape due to the difference in the number teeth between the first bevel gear and the second bevel gear which has a smaller number of teeth as the first bevel gear. The adhesive transfer tape thus receives an appropriate tension around the transfer member, and the separable sheet of paper can be reliably wound in the housing without

be broken.

  Still further, the ribbon roll, the transfer member and the roller having the second bevel gear formed thereon are detachably mounted in the housing. Thus, when the roll of tape is used until the end, the device can be used repeatedly by performing the simple operation of replacing only the cassette with another, which presents the roll of tape, the element of transfer and pebble

  with the second bevel gear.

  The invention is not limited to the embodiments shown and described in detail since various modifications can be made without departing from its scope.
