Description

The present invention relates to a tape cutter, and particularly to a technique for preventing cut tape from being rewound.

Conventional tape cutters have the disadvantage that the cut adhesive tape is rewound and stuck to the surface of the adhesive tape, making it difficult to remove it (see the abstract of Patent Document 1). Patent Document 1 discloses a tape cutter aimed at solving this problem.

In the tape cutter disclosed in Patent Document 1, two cuts are made in the tape mounting tube of the tape cutter to form a cushion mounting plate, a cushion is mounted on the cushion mounting plate, and a gap is formed between the inner circumference of the tape and the cushion. This paper attempts to solve the problem of unwinding by configuring the film to provide an appropriate contact resistance to the film (see the abstract of the same document). For this reason, a resistance force equivalent to the resistance force that prevents tape rewinding also acts when pulling out the tape, resulting in the problem that extra force is required to pull out the tape.

The tape cutter disclosed in Patent Document 2 was invented by the same inventor as the present application to solve this problem. This tape cutter has a pressing piece that prevents the rotation of the annular tape body by pressing the inner peripheral surface of the annular tape body made of an annularly wound adhesive tape. It is configured to be separated from the inner circumferential surface of the tape body.

Japanese Patent Application Publication No. 2018-140871 Patent No. 7076661

The inventor of the present application has proposed whether it is possible to create a mechanism to prevent the unwinding of an adhesive tape by utilizing the adhesiveness of the adhesive tape, instead of pressing the annular tape body to prevent its rotation. I thought. The present invention was made based on the inventor's awareness of this problem, and an object of the present invention is to provide a tape cutter that utilizes the adhesiveness of adhesive tape to prevent tape rewinding.

In order to achieve the above object, a tape cutter according to a first aspect of the present invention includes a main body, a tape cutting blade, a tape fixing member, and a movable member. The main body has a tape holder that detachably and rotatably holds an annular tape body formed by annularly wound adhesive tape. The tape cutting blade is supported by the main body and cuts the adhesive tape pulled out from the annular tape body. The tape fixing member is supported by the main body and fixes the adhesive tape by receiving adhesion from the adhesive surface of the adhesive tape. The movable member is movably supported by the main body so as to come into contact with and move away from the tape fixing member, and is urged by an elastic restoring force so as to press the tape fixing member. The tape fixing member and the movable member are positioned to sandwich the path of the adhesive tape that is pulled out from the annular tape body and reaches the tape cutting blade, and the tape fixing member is positioned to sandwich the path of the adhesive tape that is pulled out from the annular tape body and reaches the tape cutting blade. Located on the sticky side.

According to this configuration, when pulling out the adhesive tape from the annular tape body in order to use the adhesive tape, the movable member can be pushed away from the tape fixing member by the tension applied to the adhesive tape. Thereby, the adhesive tape is separated from the tape fixing member, so that the adhesive tape can be smoothly pulled out. After the adhesive tape is cut by the tape cutting blade, the pulled-out adhesive tape no longer has any tension, so the movable member presses the adhesive tape against the tape fixing member by elastic restoring force. Since the tape fixing member is located on the side of the adhesive surface of the adhesive tape, the pressed adhesive tape adheres to the tape fixing member. This prevents the adhesive tape from unwinding.

According to a second aspect of the present invention, there is provided a tape cutter according to the first aspect, in which the movable member is supported by the main body, and the movable member is moved by the elastic force such that the movable member presses the tape fixing member. It further includes a biasing member that biases by restoring force.

According to this configuration, the movable member is urged by the urging member so as to press the tape fixing member.

A third aspect of the present invention is a tape cutter according to the second aspect, in which the movable member includes a rotating body rotatably supported by the main body.

According to this configuration, when pulling out the adhesive tape, the rotating body that presses the adhesive tape to be pulled out rotates. Therefore, the adhesive tape can be pulled out more smoothly.

According to a fourth aspect of the present invention, there is provided a tape cutter according to the first aspect, wherein the movable member has a base end supported by the main body, and the movable member has elasticity of its own bending deformation as the elastic restoring force. It has a plate-like or sheet-like elastic body that is urged to press the tape fixing member by restoring force.

According to this configuration, the movable member is simply configured.

A fifth aspect of the present invention is the tape cutter according to any one of the first to fourth aspects, wherein the tape fixing member has a tape receiving surface that receives the adhesive surface of the drawn-out adhesive tape. At the destination of the adhesive tape, it escapes at an angle.

According to this configuration, the adhesive tape that has adhered to the tape receiving surface wraps around from the tape receiving surface and sticks to the tape fixing member, thereby preventing the adhesive tape from being obstructed from being pulled out.

As described above, according to the present invention, a tape cutter that utilizes the adhesiveness of adhesive tape to prevent tape rewinding is realized.

FIG. 7 is a side sectional view illustrating the configuration of a tape cutter according to still another embodiment of the present invention.

FIG. 1 is a perspective view illustrating the configuration of a tape cutter according to an embodiment of the present invention while holding an adhesive tape. FIG. 2 is a photograph of a prototype tape cutter illustrated in FIG. 1. The width of the adhesive tape 5 attached to the prototype is approximately 5 cm. Both FIG. 1 and FIG. 2 are expressed with some perspective taken into account. For example, the tape cutter 101 is configured as an industrial tape cutter that holds and cuts industrial adhesive tape. The tape cutter 101 has a main body 1 and a tape cutting blade 3.

The main body 1 has a tape holder 9 that removably and rotatably holds an annular tape body 7 in which an adhesive tape 5 is annularly wound. In the illustrated example, the tape holder 9 has a cylindrical shape and holds the annular tape body 7 by being inserted into the cavity of the annular tape body 7 . For example, the outer diameter of the cylindrical tape holder 9 is set to be smaller than the inner diameter of the annular tape body 7. Thereby, the tape holder 9 holds the annular tape body 7 with some play. The tape cutting blade 3 is supported by the main body 1, and is fixed to the main body 1 in the illustrated example. The tape cutting blade 3 is used to cut the adhesive tape 5 pulled out from the annular tape body 7. As an example, the main body part 1 is made of synthetic resin by integral molding, and the tape cutting blade 3 is made of metal.

A pair of tape fixing members 23 that fix the adhesive tape 5 by receiving adhesion from the adhesive surface of the adhesive tape 5 are supported on the main body 1 . In the illustrated example, the tape fixing member 23 is molded integrally with the main body portion 1 . A movable member 25 is further movably supported on the main body 1 so as to come into contact with and separate from the tape fixing member 23. In the illustrated example, the movable member 25 is a cylindrical rotating body. A rotating shaft 27 along the central axis of the movable member 25 is guided by a guide hole 31 formed in the main body portion 1 . Thereby, the movable member 25 is movably and rotatably supported by the main body portion 1. In the illustrated example, the guide hole 31 is formed as a long hole.

The main body 1 further supports a biasing member 33 that biases the movable member 25 so that the movable member 25 presses the tape fixing member 23 . In the illustrated example, the biasing member 33 is a leaf spring, and biases the movable member 25 by the elastic restoring force of bending deformation. The leaf spring constituting the biasing member 33 is made of metal or synthetic resin, for example. The tape fixing member 23 and the movable member 25 are arranged to sandwich the path of the adhesive tape 5 from the annular tape body 7 to the tape cutting blade 3 in the middle thereof. The tape fixing member 23 is located on the adhesive side of the adhesive tape 5, and the movable member 25 is located on the non-adhesive side.

In the illustrated example, the main body 1 includes, in addition to the tape holder 9, left and right side walls 11, and a head wall 12 that connects them. The tape holder 9 is divided into left and right parts, with the left-hand dividing piece 15 connected to the left-hand side wall 11 and the right-hand dividing piece 17 connected to the right-hand side wall 11. The tape cutting blade 3 is supported by the head wall 12 by being embedded in the head wall 12 with the tip remaining. A pair of tape fixing members 23 protrude from the left and right side walls 11 so as to face each other. In order to facilitate placement of the adhesive tape 5 between the tape fixing members 23 and the movable member 25, a gap is provided between the pair of tape fixing members 23. Guide holes 31 for guiding the movable member 25 are provided in the left and right side walls 11. The biasing member 33 that biases the movable member 25 has its base end (not shown) supported by the head wall 12 .

In the illustrated example, the main body 1 is configured to be openable and closable. A linear groove 13 is formed in the main body portion 1 along a linear connecting portion between the left and right side walls 11 and the head wall 12 . The left and right side walls 11 can be bent or extended with respect to the head wall 12 along the connecting portion where the wall thickness is reduced by the groove 13, thereby allowing the main body 1 to be opened and closed. It is now possible to do so. A linear groove 14 is formed in each of the left and right side walls 11 along a linear boundary dividing the left and right side walls 11 into an upper side wall 16 and a lower side wall 18. It is possible to open and close the left and right side walls 11 themselves along the thinned boundary portions formed by the linear grooves 14.

The left and right divided pieces 15 and 17 of the tape holder 9 are connected to a lower side wall 18. A pair of tape fastening members 23 are also connected to the lower side wall 18. A guide hole 31 for guiding the movable member 25 is provided in the upper part 16 of the side wall. In this way, the main body part 1 is configured to be able to be opened and closed in a double manner.By opening the main body part 1 along the groove 13, it is possible to attach and detach the movable member 25. This is to enable the annular tape body 7 to be replaced while the movable member 25 is attached by opening the main body 1 along the side.

FIG. 3 is a photograph of the prototype shown in FIG. 2 developed and with the annular tape body 7 removed. As shown in the illustrated example, the main body portion 1 (see FIG. 1) can be manufactured by integral molding of synthetic resin. In the illustrated example, the main body portion 1 is not opened along the groove 13 (see FIG. 1), but only along the groove 14 (see FIG. 1). That is, the side wall upper part 16 remains bent with respect to the head wall 12, and only the side wall lower part 18 is open to the side wall upper part 16. Therefore, the movable member 25 remains attached to the side wall upper part 16.

Thin portions 19 and 21 are formed at mutually opposing axial end portions of the left-hand divided piece 15 and the right-hand divided piece 17 that constitute the tape holder 9, respectively. One of the thin portions 19 is formed such that its inner circumferential surface recedes at the axial end of the left divided piece 15 . The other thin portion 21 is formed such that its outer circumferential surface recedes at the axial end of the right divided piece 17 . The left divided piece 15 and the right divided piece 17 are connected to each other in a state where the inner circumferential surface of the thin walled portion 19 and the outer circumferential surface of the thin walled portion 21 rub against each other. As a result, the connection state between the left side dividing piece 15 and the right side dividing piece 17 is maintained due to the frictional force between the circumferential surfaces that rub against each other. By applying a force that exceeds the frictional force with fingers, the left divided piece 15 and the right divided piece 17 can be separated from each other.

In this way, the left side dividing piece 15 and the right side dividing piece 17 are removable from each other. A convex portion and a concave portion are formed in corresponding portions of the inner circumferential surface of the thin wall portion 19 and the outer circumferential surface of the thin wall portion 21, and by engaging these portions, the left side dividing piece 15 and the right side dividing piece 17 are separated. The connection state may be maintained. When the left divided piece 15 and the right divided piece 17 are connected, a cylindrical tape holder 9 (see FIG. 1) is formed. At this time, the main body portion 1 is in a closed state along both the grooves 13 and 14, and has the shape illustrated in FIGS. 1 and 2.

As shown in the illustrated example, in order to maintain the state in which the side wall upper portion 16 is bent with respect to the head wall 12, the left and right side wall upper portions 16 are provided with protrusions that protrude toward each other. The protruding members 34 and 35 are connected to each other. In the illustrated example, the protruding members 34 and 35 are integrally molded with the main body portion 1. For example, thin-walled portions (not shown) are formed at the tips of the protruding members 34 and 35, similar to the left and right divided pieces 15 and 17 that constitute the tape holder 9, and these thin-walled portions provide friction. The protruding members 34 and 35 are connected to each other while rubbing against each other with force. Once the protruding members 34 and 35 are connected to each other as in the illustrated example, they cannot come any closer to each other, nor can they freely separate from each other due to frictional force, so that the left and right side walls The upper body part 16 maintains a posture bent at a set angle with respect to the head wall body 12, as shown in the illustrated example.

FIG. 4 is a side sectional view illustrating a state of the tape cutter 101 when the adhesive tape 5 is pulled out. In the illustrated example, the biasing member 33 that biases the movable member 25 is a leaf spring, and its base end is embedded in the head wall 12 . To use the tape cutter 101, the annular tape body 7 is attached to the tape holder 9, and the adhesive tape 5 is pulled out from the annular tape body 7. The drawn-out adhesive tape 5 is passed between the tape fixing member 23 and the movable member 25. The adhesive surface of the adhesive tape 5 passing between the tape fixing member 23 and the movable member 25 faces toward the tape fixing member 23.

In order to use the adhesive tape 5, when the adhesive tape 5 is pulled out in the direction approaching the tape cutting blade 3 as shown in the illustrated example, the movable member 25 is moved by the biasing member 33 due to the tension applied to the adhesive tape 5 being pulled out. It is pushed against the force and separates from the tape fixing member 23. The tip of the adhesive tape 5 that has been pulled out is affixed to an object such as the surface of a cardboard box, and while holding the main body 1 in the hand, the adhesive tape is removed by moving it in a direction away from the area where it was affixed. 5 is continuously fed out from the annular tape body 7, and the adhesive tape 5 can be continuously attached to the object. In this case as well, the pulled out adhesive tape 5 separates the movable member 25 from the tape fixing member 23 due to tension. When the movable member 25 is pushed away from the tape fixing member 23 by being pushed by the adhesive tape 5, the adhesive surface of the adhesive tape 5 separates from the tape fixing member 23. Therefore, the adhesive tape 5 can be pulled out smoothly.

FIG. 5 is a side sectional view illustrating a state of the tape cutter 101 when the adhesive tape 5 is not pulled out. When the pulled-out adhesive tape 5 is cut by the tape cutting blade 3, the pulled-out adhesive tape 5 loses tension, so the movable member 25 presses the adhesive tape 5 against the tape fixing member 23 by the urging force of the urging member 33. do. Since the tape fixing member 23 is located on the side of the adhesive surface of the adhesive tape 5, the pressed adhesive tape 5 adheres to the tape fixing member 23. This prevents the adhesive tape 5 from being rewound. When pulling out the adhesive tape 5 again, as described above, the movable member 25 moves in the direction away from the tape fixing member 23, so the adhesive tape 5 separates from the tape fixing member 23, and the adhesive tape 5 adheres to the tape fixing member 23. The condition is canceled. As described above, in the tape cutter 101, by utilizing the adhesive force of the adhesive tape 5, the unwinding of the pulled out adhesive tape 5 is prevented, and at the same time, the tape cutter 101 prevents the unwinding of the pulled out adhesive tape 5, and does not receive as much resistance as the resistance force that prevents unwinding. The adhesive tape 5 can be pulled out.

FIG. 6 is a perspective view illustrating various forms of the movable member 25 included in the tape cutter 101. The form illustrated in FIG. 6(a) is a cylindrical rotating body illustrated in FIGS. 4 and 5. The movable member 25 is rotatably and movably supported by the main body 1 by having a rotating shaft 27 guided through a guide hole 31 formed in the main body 1 . On the other hand, FIGS. 6(b) and 6(c) illustrate a configuration in which the movable member 25 is not rotatable. As illustrated in FIG. 6(c), the movable member 25 can also be shaped as a non-rotating body. 4(a), (b), and (c) show an example in which a leaf spring, which is already bent to some extent in its natural state, is further elastically bent as the urging member 33 that urges the movable member 25. Although shown, a flat leaf spring that does not bend may be used by simply bending elastically.

When the adhesive tape 5 is pulled out for use, the adhesive tape 5 presses the movable member 25 and separates from the tape fixing member 23. Since the adhesive surface of the adhesive tape 5 faces the tape fixing member 23 and the non-adhesive surface faces the movable member 25, the adhesive tape 5 does not adhere to the movable member 25. Therefore, even if the movable member 25 is not rotatably supported by the main body 1, the resistance force by the movable member 25 when pulling out the adhesive tape 5 is due to the adhesive tape 5 adhering to the tape fixing member 23. This is much smaller than the resistance force that prevents unwinding. Therefore, the adhesive tape 5 can be smoothly pulled out without being hindered by the tape fixing member 23 or the movable member 25.

In the form illustrated in FIG. 6A, the movable member 25 is rotatable, so when the adhesive tape 5 is pulled out, the movable member 25 rotates so as to send out the adhesive tape 5. Therefore, the resistance force exerted by the movable member 25 when pulling out the adhesive tape 5 is smaller than that in the embodiments illustrated in FIGS. 6(b) and 6(c). Furthermore, since the movable member 25 is rotatable, even when the adhesive tape 5 is of a double-sided tape type with adhesive surfaces on both sides, the resistance due to the movable member 25 can be kept low when pulling out the adhesive tape 5. That is, the form of FIG. 6(a) also makes it possible to use a double-sided tape type as the adhesive tape 5.

FIG. 7 is a side sectional view illustrating the configuration of a tape cutter according to another embodiment of the present invention. In this tape cutter 102, the movable member 25 has a plate-like or sheet-like shape whose base end is supported by the main body 1 and is biased to press the tape fixing member 23 by the elastic restoring force of its own bending deformation. It is constructed as an elastic body. In the illustrated example, the movable member 25 is a plate spring, and its base end is supported by the head wall 12 by being fitted into a support hole 37 formed in the inner wall surface of the head wall 12. . The leaf spring constituting the movable member 25 is made of metal or synthetic resin, for example.

In order to use the adhesive tape 5, when the adhesive tape 5 is pulled out in the direction approaching the tape cutting blade 3 as shown in the illustrated example, the movable member 25 presses the tape fixing member 23 due to the tension applied to the adhesive tape 5 being pulled out. It is pushed against its own biasing force and moves away from the tape fixing member 23 (see movable member 25 indicated by a solid line). In order to limit excessive movement of the movable member 25, the main body portion 1 is provided with a limiting member 39. For example, like the pair of tape fixing members 23, the limiting members 39 are integrally molded with the main body 1, and protrude from the left and right side wall upper portions 16 of the main body 1 so as to face each other. The limiting member 39 may also serve as the protruding members 34 and 35 illustrated in FIG. 3 . When the movable member 25 is pushed away from the tape fixing member 23 by being pushed by the adhesive tape 5, the adhesive surface of the adhesive tape 5 separates from the tape fixing member 23. Therefore, the adhesive tape 5 can be pulled out smoothly.

When the pulled out adhesive tape 5 is cut by the tape cutting blade 3, the pulled out adhesive tape 5 loses its tension, so the movable member 25 presses the adhesive tape 5 against the tape fixing member 23 by its own elastic restoring force ( (see movable member 25 represented by dotted lines). Since the tape fixing member 23 is located on the side of the adhesive surface of the adhesive tape 5, the pressed adhesive tape 5 adheres to the tape fixing member 23. This prevents the adhesive tape 5 from being rewound. When pulling out the adhesive tape 5 again, as described above, the movable member 25 moves in the direction away from the tape fixing member 23, so the adhesive tape 5 separates from the tape fixing member 23, and the adhesive tape 5 adheres to the tape fixing member 23. The condition is canceled.

As described above, in the tape cutter 102 as well, by utilizing the adhesive force of the adhesive tape 5, the unwinding of the pulled out adhesive tape 5 is prevented, and at the same time, the tape cutter 102 does not receive as much resistance as the resistance force that prevents unwinding. The adhesive tape 5 can be pulled out. Further, in the tape cutter 102, the movable member 25 is simply configured.

FIG. 8 is a perspective view illustrating various forms of the movable member 25 that can be used in the tape cutter 102. The form illustrated in FIG. 8(a) is the leaf spring illustrated in FIG. 7. The movable member 25 in the illustrated example has a proximal end bent such that it can be fitted into a support hole 37 provided in the head wall 12. The distal end portion of the movable member 25 is gently curved so as to smoothly follow the drawn-out adhesive tape 5. When the proximal end portion is pushed into the support hole 37, the proximal end portion is stably held in the support hole 37 by elastically deforming so as to open the bending angle. By holding the movable member 25 between fingers and pulling it with a certain amount of force, the proximal end portion can be pulled out from the support hole 37. In this way, the movable member 25 illustrated in FIG. 8(a) is easy to replace.

In the form illustrated in FIG. 8(b), a protective member 41 is provided at the tip of the leaf spring so that the tip of the leaf spring does not irritate the fingers. In the illustrated example, the protection member 41 has a cylindrical shape and is made of, for example, synthetic resin. The tip of the leaf spring is embedded in the protection member 41 and bonded, for example, with an adhesive. If both the leaf spring and the protection member 41 are made of synthetic resin, they may be integrally molded. In the form illustrated in FIG. 8(c), the protection member 41 is formed by curving the tip of a leaf spring into a cylindrical shape. Moreover, as illustrated in FIG. 8(c), a cavity may be formed in the leaf spring as appropriate.

As illustrated in FIG. 8(d), it is also possible to use a leaf spring whose tip portion is not curved as the movable member 25. Furthermore, as illustrated in FIG. 8(e), a flat leaf spring whose base end cannot be bent may be used as the movable member 25. The movable member 25 of this form is supported by the head wall 12 by having its base end embedded in the head wall 12, for example, similarly to the biasing member 33 illustrated in FIGS. 4 and 5. .

FIG. 9 is a side sectional view illustrating the configuration of a tape cutter according to yet another embodiment of the present invention. In this tape cutter 103, the movable member 25 has the form illustrated in FIG. 8(b), and has a protective member 41 at its tip. Similar to FIG. 7, the state of the movable member 25 when the adhesive tape 5 is pulled out is represented by a solid line. Furthermore, the state of the movable member 25 after the drawn-out adhesive tape 5 is cut by the tape cutting blade 3 is represented by a dotted line.

FIG. 10 is a side sectional view illustrating the configuration of a tape cutter according to yet another embodiment of the present invention. This tape cutter 104 has an external shape of the tape fixing member 23 in that the tape receiving surface 43, which is a surface for receiving the adhesive surface of the drawn-out adhesive tape 5, escapes at an angle at the destination of the adhesive tape 5. This is different from the tape cutter 102 illustrated in 7. In the illustrated example, the tape receiving surface 43 is connected to a flank surface 44 bent at an angle at the end in the direction in which the adhesive tape 5 is fed.

By providing such a relief angle on the tape receiving surface 43, the adhesive tape 5 stuck to the tape receiving surface 43 wraps around from the tape receiving surface 43 and sticks to the tape fixing member 23, and furthermore, It is possible to prevent the adhesive tape 5 from sticking to a portion of the pulled-out adhesive tape 5 closer to the annular tape body 7 than the tape fixing member 23 or to the annular tape body 7, thereby preventing the adhesive tape 5 from being obstructed from being pulled out. In the illustrated example, the relief surface 44 is bent at an acute angle with respect to the tape receiving surface 43. The relief angle may not be an acute angle, but may be a right angle or an obtuse angle.
