Description

Tape cutter

The present invention relates to a tape cutter for supplying an adhesive tape, and in particular, for a next cutting tape, a tab that becomes a non-adhesive picking portion in which adhesive surfaces are bonded to each other at a fixed length at the tip of the cut adhesive tape. The present invention relates to a tape cutter to be formed.

Conventionally, tape cutters for adhesive tapes have been used in a wide range of fields, and tape cutters have become established as indispensable instruments from daily life to business use. At present, many techniques for improving the function of the tape cutter and improving usability have been developed. For example, the applicant of this case is a developer of a tape cutter disclosed in Japanese Patent Application Laid-Open No. 2005-75560, Japanese Patent Application Laid-Open No. 2006-103808, etc., and is engaged in other research and development of a tape cutter with improved functionality. is doing.

The basic structure of a tape cutter consists of a tape cutter body, a tape holding part, and a tape cutting part. A roll-shaped tape with an adhesive tape wound around the tape holding part is installed, and the adhesive tape is pulled out. The tape holding part rotates and is cut by the tape cutting part. The leading end of the residual tape is in a state where it is used for the next use while being adhered to the tape cutting portion, and an arbitrary length of tape cutting pieces are sequentially supplied as necessary.

As a usage mode of the cut adhesive tape supplied with the tape cutter, it is considered that the purpose is often to adhere the packaging and the like so as not to peel off. For example, for business use, it is used for packing goods with packaging paper at supermarkets and department stores, and for packing envelopes and parcels. . For example, in order to prevent the parts from floating in the packaging during distribution of an electric product or the like, it is widely and generally performed to temporarily fasten each part with an adhesive tape.

However, depending on the degree of adhesion of the pressure-sensitive adhesive tape, the pressure-sensitive adhesive tape may be strongly adhered to the object and difficult to peel off. As one means of improving this, the end of the adhesive tape is folded to the adhesive tape side, the adhesive surfaces are bonded together to form a tab that becomes a non-adhesive knob, and this tab is easily picked. Ingenuity to make it peelable is routinely performed in various fields.

There is a technique disclosed in Japanese Patent Application Laid-Open No. 11-49419 as a technique related to a tape cutter in which the formation of a tab serving as a knob provided at the end of such an adhesive tape is semi-automated. In the present invention, when forming a tab at the tip of the cut tape, the tape cutter includes a cutter mechanism for cutting the adhesive tape, a folding mechanism for folding the tip surface of the residual tape, and a folding process for the folded portion. Each of the mechanisms has a folding mechanism, and the cams provided in each mechanism may cause a shift in the linkage operation of the adhesive tape cutting process, the remaining tape tip folding process, and the folding part folding process. A technique for forming a tab at the tip of an adhesive tape to be pulled out in preparation for the next cutting is disclosed.

According to the disclosed technology, although the tab is accurately formed at the end of the residual tape, the tape folding timing is delicate, so that there is a problem that the tab cannot be formed if the accuracy is slightly shifted. It was. In addition, since the accuracy of the equipment is required, there is a problem that the production cost of the tape cutter is high.

Further, in JP-A-2004-284687, the adhesive tape is cut in a state where the movable cutter portion is pivotally moved apart and temporarily adhered to the temporary attachment receiving portion, and the movable cutter portion is returned and rotated by a spring, whereby the tab is removed. A forming technique is disclosed. According to this technique, an inexpensive and highly durable tape cutter can be manufactured, but there is a problem that it is difficult to reliably form a tab in the upward direction. In addition, since there are various types of adhesive tapes depending on applications such as strength and width, it cannot be said that all types of adhesive tapes are supported. Furthermore, since the cutter is always exposed to the outside, there is a risk of accidental injury during use or storage.

Accordingly, there has been a demand for the development of a tape cutter that is capable of forming a tab as a knob accurately without making the structure too complicated and having excellent safety.

Hereinafter, a tape cutter according to the present invention will be described in detail based on an embodiment shown in the drawings. FIG. 1 is a perspective view of the tape cutter of the present invention. FIG. 2 is a perspective view of the tape cutter with the cover removed, and FIG. 3 is a transparent perspective view of the tape cutter. FIG. 4 is a side perspective view of the tape cutter in a standby state, and FIG. 5 is a side perspective view of the tape cutter when cutting is completed. 6 is a side perspective view of the tape cutter when the tab formation is completed, and FIG. 7 is a perspective view of the tape cutting portion.
As shown in FIG. 1, the tape cutter of the present invention includes a tape cutter main body 10, a tape holding unit 20, an adhesive tape 25, a tape delivery unit 30, a tab forming unit 40, and a tape cutting unit 50. .

As shown in FIG. 1, the tape holding unit 20 is configured to hold the wound adhesive tape 25 so as to be rotatable. In this embodiment, the tape holding part 20 uses a resin material. In order to prevent the posture of the tape cutter from becoming unstable due to the force with which the tape cutter body 10 pulls out the adhesive tape 25 when the adhesive tape 25 is pulled out, iron, lead, It is desirable to use heavy materials such as clay and concrete.

The adhesive tape 25 is rotatably held by the tape holding unit 20 in a wound state, and is sent out through the tape sending unit 30 that sends the adhesive tape 25 to the tape cutting unit 50 by a pulling operation. Adhesive surfaces are bonded to the leading end surface of the tape (the leading end of the pulled-out remaining tape) with a certain length to form a tab serving as a knob, and the tab of the tab is cut during the next tape cutting. The formed tape is sent to the tape cutting unit 50 so as to be cut.

The tape delivery unit 30 is configured to send the adhesive tape 25 from the tape holding unit 20 to the tape cutting unit 50. As shown in FIG. 2, the tape delivery unit 30 includes a swing plate 32, a tape feed roller 34 to which a swing gear 35 is fixed, and an urging roller 36.

The swing plate 32 is configured to swing back and forth by the pulling force / restoring force according to the pulling operation of the adhesive tape 25. In this embodiment, the swinging plate 32 swings around a shaft 37 provided between the urging roller 36 and the tape feed roller 34. The urging roller 36 is configured to oscillate the oscillating plate 32. When the adhesive tape 25 is pulled out, a force required to pull out the adhesive tape is applied to the urging roller 36. Is configured to swing back and forth around the center.

The tape feeding roller 34 is a roller body to which a swing gear 35 is fixed, and is rotatably held at an end opposite to the biasing roller 36 with the shaft interposed therebetween as shown in FIG. In this embodiment, the oscillating gear 35 is fixed at a position sandwiching the oscillating plate 32, and the oscillating gear 35 rotates in accordance with the rotation of the tape feed roller 34.

The tape delivery roller 34 is in contact with the adhesive surface of the adhesive tape 25 and rotates upon receiving the pulling force of the adhesive tape. As will be described later, the rotational force meshes with a fixed gear 66 (described later) via the swing gear 35 and transmits the rotational force to the tab formation control mechanism 60. For this reason, it is desirable that the adhesive tape slide on the tape feed roller 34 so that the rotational force is not lost. Therefore, in this embodiment, as shown in FIG. 2, tension rollers 39a and 39b are provided in the vicinity of the tape feed roller 34 of the swing plate 32 and the tape cutter body 10 so that the adhesive tape 25 is in contact with the tape feed roller 34. It is configured to increase.

The tab forming part 40 is a structure for forming a tab to be a knob part in which the adhesive surfaces are bonded to the tip of the remaining adhesive tape 25 with a certain length for the next cutting tape, the movable part 42, The load suppression roller 43, the tab formation base 44, and the tab formation control rod 46 are configured.

The movable part 42 is configured to hold the adhesive tape 25 delivered from the tape delivery part 30 in a horizontal contact with the adhesive surface down, and is mounted on the tape cutter body 10 so as to be movable back and forth. Since the adhesive tape 25 is sent toward a tab forming base 44 or a tape cutting unit 50 described later via the movable portion 42, it is desirable to suppress a load caused by friction generated when the movable portion 42 contacts the adhesive tape. In this embodiment, as shown in FIG. 2, a load suppression roller 43 is provided on the tab forming portion 40 side of the movable portion 42 to suppress a load caused by friction with the adhesive tape 25.

The tab forming base 44 is configured to form a tab having a non-adhesive surface on both sides that become the knobs at the tip of the remaining adhesive tape 25, and is held at a position in contact with the movable portion 42 in the standby state of the tape cutter. . When the adhesive tape 25 is pulled out, the tape is rotated in the direction in which the tape is pulled out together with the tape cutting unit 50, and when the tape cutting by the tape cutting unit 50 is completed, the remaining tape that has been pulled out, that is, the adhesive tape 25 of the cutting base. A series of operations are performed in such a manner that the tip of the lens is held and rotated back to the original position. During this reversal rotation, the remaining tape that has been pulled out and remains on the movable portion 42 is not reverted and is held in that position, so that the cut-out adhesive tape 25 held by the tab forming base 44 When the front end approaches the adhesive tape located on the movable portion 42 and the adhesive surfaces are bonded and bonded together, the adhesive surface is folded inward at the leading end of the drawn-out remaining tape, and the outer side becomes a non-adhesive surface. A tab is formed.

The tab formation control rod 46 is mounted in the vicinity of the rotation axis of the tab formation base 44, abuts on a tab formation portion control cam 64, which will be described later, receives the force transmitted by the rotational movement of the cam, and moves the tab formation base 44 back and forth. Move.

The tab forming unit 40 is further equipped with a tab forming control mechanism 60. The tab formation control mechanism 60 is a device for controlling the front and rear rotational operations for tab formation by the tab formation portion 40, and as shown in FIG. 3, a cam control gear 62, a tab formation portion control cam 64, Consists of.

The cam control gear 62 is a gear body that receives the rotational force from the rocking gear 35 during the tape drawing operation and rotates in accordance with the drawing of the adhesive tape 25. After the adhesive tape 25 is cut, the transmission of the rotational force from the swing gear 35 is released, and the cam control gear 62 can be rotated in the reverse direction and returns to the standby state.

The tab forming portion control cam 64 is a cam-like member that abuts on the tab forming control rod 46 and swings the tab forming base 44 according to the shape of the cam when the tab forming portion control cam 64 rotates. The cam control gear 62 is fixed and rotates together with the cam control gear 62.

When the tape is pulled out, the cam control gear 62 is rotated by the transmission of the rotational force from the rocking gear 35, and at the same time, the tab forming portion control cam 64 is rotated, whereby the force is transmitted to the tab forming control rod 46 to form the tab. The base 44 moves in the tape feeding direction. Since the transmission of the rotational force from the swing gear 35 is released after the tape cutting is completed, the cam control gear 62 rotates in the reverse direction, and the tab forming portion control cam 64 also rotates in the reverse direction to return to the original position. The transmission of force to the formation control rod 46 is also released, and the tab formation base 44 is also retracted and returned to its original position.

Next, the operation of the tape cutter according to the present invention will be described sequentially with reference to the drawings. In the tape cutter of the present invention, in the standby state before the tape is pulled out, as shown in FIG. 4, the swing plate 32 is a restoring force of the swing control elastic body 38 fixed to the tape cutter body 10 and the swing plate 32. It is fixed by. In this embodiment, in order to transmit the rotational force of the oscillating gear 35 to the cam control gear 62, a fixed gear 66 that is rotatably fixed to the tape cutter body 10 is provided. It is held away. In this state, the tab forming base portion 44 and the tape cutting portion 50 are held at a position in contact with the movable portion 42.

When pulling out the tape, the urging roller 36 of the tape delivery unit 30 swings the swinging plate 32 by the pulling force of the adhesive tape 25. With this operation, as shown in FIG. 5, the swing gear 35 fixed to the tape feed roller 34 moves and meshes with the fixed gear 66, so that the rotational force of the tape feed roller 34 can be transmitted. When the adhesive tape 25 is further pulled out, the tape feed roller 34 rotates, whereby the swing gear 35 and the fixed gear 66 rotate in conjunction with each other, and the rotational force is transmitted to the cam control gear 62. Since the tab forming portion control cam 64 rotates with the rotation of the control gear 62, the tab forming control rod 46 moves in accordance with the shape of the rotating tab forming portion control cam 64 as shown in FIG. The forming base 44 and the tape cutting unit 50 move in the tape feeding direction. Thereby, the adhesive tape 25 can be cut.

In this embodiment, as shown in FIG. 5, the two gears are provided between the fixed gear 66 and the cam control gear 62. However, the present invention is not limited to this embodiment, and the fixed gear 66 is not limited thereto. The cam control gear 62 may be directly connected. Further, it is conceivable that a rotational force is transmitted to the cam control gear 62 via a single gear or a plurality of gears.

When the tape cutting is completed, the end of the remaining tape from which the tab forming base 44 has been pulled out is stuck and held. Since the tape cutting part 50 is provided alongside the tab forming base 44 and has a cutter 52 and responds to the back and forth movement of the tab forming base 44, the tape cutting part 50 is pulled out as shown in FIG. It is desirable to have a configuration in which the remaining tape that remains is pasted and held, and the tab can be formed more reliably.

After completion of the tape cutting, the rocking gear 35 is moved in the reverse direction by the restoring force of the rocking control elastic body 38 and the meshing with the fixed gear 66 is released. Thereby, the rotational force to the cam control gear 62 is released, and the cam control gear 62 can rotate in the reverse direction.

The cam control gear 62 is provided with a tab forming elastic body (not shown). Due to the restoring force of the tab forming elastic body, the cam control gear 62 and the tab forming portion control cam 64 are reversely rotated, and accordingly, the tab forming base portion 44 and the tape cutting portion 50 are also reversely rotated. In this embodiment, the tab-forming elastic body uses a string spring, but is not limited to this.

At the time of this reverse rotation, as shown in FIG. 6, the remaining tape that has been pulled out and remains on the movable portion 42 is not reversed and is held in that position, so that the cut held by the tape holding portion 58 is retained. The leading end of the base adhesive tape approaches the adhesive tape 25 located at the tape locking portion 48 on the movable portion 42, and a tab is formed at the leading end of the drawn-out remaining tape.

The tape cutting unit 50 is configured to cut the drawn adhesive tape 25. As shown in FIG. 7, the tape cutting unit 50 includes a cutter 52, a cutter holder 54 that fixes the cutter, and a cutter cover 56 that is mounted so as to be movable up and down. Composed.

The tape cutting unit 50 can be separated and moved from the tab forming base 44 when the tape is pulled out, and can be engaged with the tab forming base 44 after the tape cutting is completed. With this configuration, when the tape cutting unit 50 is configured to affix and hold the pulled-out residual tape, a sufficient interval between the movable unit 42 and the tape cutting unit 50 is secured when the tape is pulled out, and the remaining tape is It becomes possible to make the structure easy to stick.

As shown in FIGS. 4 and 5, the tape cutting unit 50 can be cut by moving the cutter cover 56 downward to expose the cutter 52 when the tape is pulled out. The cutter 52 is stored and held by moving upward. Thereby, since the cutter 52 is not exposed in the standby state before the tape is pulled out, it is possible to prevent an injury caused by a finger or the like directly contacting the cutter 52 and to provide a safe tape cutter. .

The movable part 42 of the tab forming part 40 is configured to be attached to the tape cutter main body 10 so as to be movable back and forth in accordance with the tape drawing operation. The oscillating plate 32 and the cam control gear 62 are configured to rotate in reverse by the restoring force of the oscillating control elastic body 38 and the restoring force of the tab forming elastic body (not shown), respectively, when the tape cutting is completed. However, if the tension of the adhesive tape 25 is strong, the swing plate 32 cannot be rotated in the reverse direction, and the meshing between the swing gear 35 and the fixed gear 66 cannot be released.

In order to avoid this, the movable part 42 moves in the tape feeding direction when the tape is pulled out, and the movable part 42 moves backward when the tape cutting is completed. Thereby, since the tension of the adhesive tape 25 is released when the tape cutting is completed, the swing plate 32 easily reversely rotates, and the meshing between the swing gear 35 and the fixed gear 66 is released. As a result, the cam control gear 62 can rotate in the reverse direction and returns to the standby state. Since the tab forming base 44 and the tape cutting part 50 also surely return to their original positions, it is possible to form a tab on a stable adhesive tape.

As shown in FIGS. 2 and 7, the tape cutting unit 50 can be configured to include a tape holding unit 58 that holds the remaining tape drawn at the time of cutting. In other words, the tape cutting unit 50 rotates in the reverse direction and returns to the original position with the tape remaining at the time of cutting attached to the tape holding unit 58.

Further, as shown in FIG. 2, the movable portion 42 can be configured to include a tape locking portion 48 for preventing the pulled-out residual tape from peeling off. In order to form the tab on the correctly drawn remaining tape, the drawn remaining tape positioned on the movable portion 42 needs to be held in the position without being reversed. As a result, the pulled-out residual tape is held in a state of being bonded on the movable portion 42.

This makes it possible to prevent the remaining tape from being pulled off and to form a stable tab. Since the tape holding portion 58 and the tape locking portion 48 need to be securely attached and held on the adhesive tape, in this embodiment, urethane or the like is used as each material. However, the present invention is not limited to this. However, it is possible to select a material as appropriate.

The tab forming base 44 is equipped with a non-adhesive top surface 49. The non-adhesive upper surface 49 is made of a non-adhesive material and is made of a material to which the adhesive tape 25 does not adhere. As shown in FIG. 5, the non-adhesive upper surface 49 is mounted between the tape holding portion 58 and the tape locking portion 48 so as to contact the adhesive surface of the adhesive tape 25 and urge the tape upward when the tape is pulled out. Is done. Thereby, when forming a tab in the pulled-out residual tape, it became possible to prevent a tab from bending to the reverse side (downward), and to join adhesive surfaces reliably.

As the tape feed roller 34, the tension rollers 39a and 39b, the urging roller 36, and the load suppression roller 43, it is possible to use a barrel shape whose diameter increases from the roller end toward the center. If the straightness of the adhesive tape 25 in the tape cutter body 10 is impaired, it is difficult to form a reliable tab. By using the barrel shape, it is possible to ensure the straightness of the adhesive tape 25 when the adhesive tape is delivered, and a stable tab can be formed. In addition, the shape of each roller is not limited to a barrel shape, and it is possible to appropriately select a shape that allows straightness of the adhesive tape to be obtained.

Further, the tape holding unit 20 can be equipped with a torque adjusting mechanism 24. The torque adjusting mechanism 24 is configured to adjust the rotational torque of the reel 22 that holds the adhesive tape 25. In this embodiment, the torque adjusting mechanism 24 is configured to control the rotational torque by tightening the screws. As a result, even adhesive tapes with different widths, thicknesses, sizes, and adhesion levels can be stably introduced into the device to form tabs, and all types of adhesive tapes can be used. It became.
