Description

  The present invention relates to an electric tape cutter that supplies a pressure-sensitive adhesive tape that has been electrically cut, and in particular, forms a non-adhesive bonding surface that becomes a knob with adhesive surfaces adhered to the tip of the adhesive tape at a certain length. The present invention relates to an electric tape cutter that automatically supplies an adhesive tape with a knob in a state of being cut.

  Conventionally, a series of processes for automatically feeding adhesive tape by rotating an electric drive device, deriving only the required dimensions from the delivery port, and cutting and supplying with a cutting blade installed at the delivery port at a predetermined length are automatically performed. Electric tape cutters have been developed. For example, the applicant of this case is an applicant of an electric tape cutter disclosed in Japanese Patent Application Laid-Open No. 2006-103808, and is also engaged in research and development of this type of tape cutter.

  The basic structure of the electric tape cutter operates a drive mechanism consisting of a plurality of gears, rotation from the drive source is transmitted to the roller of the adhesive tape feeding mechanism, and the tape held by the tape holding mechanism is rotated by the rotation of the roller. It is an apparatus having a configuration in which the distal end portion is delivered from the delivery port, and is cut and discharged by a cutting mechanism provided at the delivery port at an appropriate length. This type of apparatus has a structure in which when the adhesive tape is taken out from the delivery port, the next tape is automatically delivered and repeatedly delivered and supplied one after another at an appropriate length. This apparatus is indispensable as a kind of automatic processing apparatus, and is used in various fields.

  The usage of the cut adhesive tape supplied by the electric tape cutter is overwhelmingly intended to stick packaging and not peel off, but on the other hand, tape is stuck Is often intended to be removed from the beginning. For example, in order to prevent the components from floating in the packaging during distribution of an electrical product or the like, each component is temporarily fastened with an adhesive tape. However, depending on the adhesive strength of the pressure-sensitive adhesive tape and the degree of temporary fastening, the pressure-sensitive adhesive tape may be difficult to peel off and may not be easily peeled off, which may be difficult to remove. Therefore, what is routinely performed in various fields is a device that folds the ends of the adhesive tape and sticks the adhesive surfaces together to form a non-adhesive bonding surface at the tip that becomes the knob. Yes. This makes it easy to remove the temporarily fixed adhesive tape.

  A technique disclosed in Japanese Patent Application Laid-Open No. 11-49419 is a technique that automates the formation of a non-adhesive joint surface that becomes a knob provided at the end of a temporary fastening adhesive tape. In this invention, in forming the non-adhesive joint surface, the adhesive tape cutter includes a cutter mechanism for cutting the adhesive tape, a folding mechanism for folding the cut portion, and a folding mechanism for folding the folded portion. Each is provided with a periodic motion by a cam provided in each mechanism, thereby forming a non-adhesive joint surface. Among them, by using a single drive motor for driving the tape feeding mechanism and the tape end processing mechanism, the adhesive tape cutting process, the cutting part folding process, by the first to third cams of the cam mechanism, The timing of the folding process of the folding portion is given, and it has been devised to ensure that a series of operations are performed without causing any deviation in the linked operations of these various processes.

  In the disclosed technology, the non-adhesive joint surface of the tape is accurately formed by a series of operations, but the timing of tape folding is delicate, and the timing is slightly due to wear and deformation of parts due to long-term use. If it deviates, there is a problem that it becomes impossible to form a non-adhesive bonding surface of the tape. In addition, since the processing requiring such delicate timing is performed, the configuration of the apparatus becomes complicated, and the production cost of the tape cutter increases. In addition, a series of tape folding operations need to be performed instantaneously at exquisite timing, and the bonding surfaces of the tape are bonded instantaneously. There was also a structural problem that would peel off.

Electric tape cutters are usually used continuously for a long time in factory production lines, product packaging, etc., and if the above problems occur, it means that the entire work is stopped. Therefore, it was a situation that the user naturally wanted to avoid.
Therefore, the electric tape has rigidity and durability that can withstand long-term use because it can form a non-adhesive bonding surface that accurately becomes a knob, at a low cost without being too complicated in structure. The development of a cutter was desired.

  In order to solve the above problems, the present invention is an electric tape cutter, particularly in a state in which the adhesive surfaces of the tape are bonded to each other with a certain length to form a non-adhesive bonding surface that becomes a knob. An object of the present invention is to provide an electric tape cutter that supplies an adhesive tape by cutting it into an appropriate length.

  In order to achieve the above object, an electric tape cutter according to the present invention includes a drive mechanism comprising a plurality of gears for transmitting rotation from a drive source to a roller of a tape feed mechanism, a tape holding mechanism for holding an adhesive tape, A tape feeding mechanism comprising a roller for feeding the tape held by the tape holding mechanism to a cutting mechanism, and a cutting mechanism for cutting the tape fed from the tape feeding mechanism to the delivery port, and is mounted on the roller. This is an electric tape cutter that feeds the tip of the adhesive tape from the delivery port and cuts it by a cutting mechanism provided at the delivery port at an appropriate length, and fixes the adhesive tape coated with adhesive on one side of the delivery. And a tape folding means that folds the fixed tip portion of the fixed tape in the direction of the adhesive surface with a fixed width. A structure for supplying and cutting the tape to a predetermined length in a state of forming a non-adhesive bonding surface to be bonded to the knob portion by the length of the constant.

The tape fixing means has a structure in which the surface of the tape having an adhesive applied on the back surface is sucked up and fixed by a tape suction mechanism that sucks up and sucks the surface of the tape using a suction device.
Further, the tape fixing means has a structure that is provided inside the tape delivery outlet for delivering the front end portion of the adhesive tape and on the upper surface side of the adhesive tape to be delivered.
Also, the tape folding means is composed of a rotatable flap, and the adhesive surface on the back surface of the tape with the tape adsorbed and fixed in order to form a non-adhesive joint surface that becomes a knob portion by sticking the adhesive surfaces together. By rotating to the side, the tape is folded at a certain length from the cut portion.

The tape folding means is a non-adhesive joint surface that performs a tape folding process after the tape delivered by the tape feeding mechanism is cut by the cutting mechanism, and presses the adhesive surfaces together to form a knob that is difficult to peel off. In order to form the tape, the flap after the rotation operation holds the tape pressing state until the tape is fed again even after the tape is folded.
Further, the tape folding means has a structure in which a tape floating preventing member is provided at the tip of the flap.
The anti-floating member has a configuration made of a rubber material.
Furthermore, the electric tape cutter is equipped with a tape support roller that is rotated by the rotation of the drive source to prevent the tape sent from the tape feeding mechanism to the tape cutting mechanism between the cutting mechanism and the tape feeding mechanism. It is also a configuration.

Since the present invention is configured as described in detail above, the following effects are obtained.
1. It is cut in a state where the tip of the adhesive tape with the adhesive applied only to the fed back surface is folded in the direction of the adhesive surface, which is the back surface, with a certain length to form a non-adhesive bonding surface that easily becomes a knob. Tape can be provided.
2. Since the means for fixing the tape is a structure that sucks and fixes the surface of the tape with a suction device, the tape can be fixed without touching the adhesive surface of the tape, and the reduction in the adhesive strength of the tape can be suppressed. it can. Further, since the structure is relatively simple, the manufacturing cost can be suppressed.

3. There is a means for adsorbing and fixing the tape inside the tape delivery outlet that feeds the tip of the adhesive tape, and it is installed above the surface of the tape, so it is possible to adsorb the tape at a position where blurring does not occur during folding operation it can. Moreover, since it attracts | sucks upwards, the operation | movement of the folding mechanism with respect to the back surface direction to which the adhesive material was apply | coated can be made easy.
4). Since the tape folding means comprises a simple rotatable flap, it has a simple structure that is not easily damaged. In addition, the tape is folded by rotating to the tape adhesive surface side in the tape adsorption fixed state, and the adhesive surfaces are adhered to each other to form a non-adhesive bonded surface. The structure can withstand the use of
5. Since the tape folding mechanism keeps the tape pressed down until the tape is fed again even after the tape is folded, the adhesive surfaces are crimped at least until the next use. A non-adhesive bonding surface that is difficult to peel off can be formed.

6). Since the tape anti-floating member is attached to the tip of the flap of the tape folding mechanism, the tape is not easily displaced when the non-adhesive bonding surface is formed by folding, and a clean and uniform non-adhesive bonding surface can be formed.
7). Since the anti-floating member is made of rubber, the tape is less likely to slip.
8). By providing a tape support roller that is rotated by a drive source between the tape cutting mechanism and the tape feeding mechanism, it is possible to prevent the tape fed from the tape feeding mechanism to the tape cutting mechanism from hanging down.

Hereinafter, an electric tape cutter according to the present invention will be described in detail based on an embodiment shown in the drawings.

FIG. 3 is a plan view of the electric tape cutter of the present invention, and FIG. 4 is a front view of the electric tape cutter of the present invention. FIG. 5 is a perspective view of the tape feeding mechanism, and FIG. 6 is a perspective view of the mechanism for fixing the adhesive tape. FIG. 7 is a perspective view of the tape folding mechanism, and FIG. 8 is a perspective view when the tape folding mechanism is operated. FIG. 9 is a perspective view of the tape cutting mechanism, and FIG. 10 is a perspective view when the tape support roller is used.
The electric tape cutter 10 of the present invention includes a main body 20, a driving mechanism 30, a tape holding mechanism 40, a tape feeding mechanism 50, a cutting mechanism 60, a tape feeding outlet 70, a tape fixing means 80, and a tape folding means. 90.

  The main body 20 is a frame member that includes the drive mechanism 30, the tape holding mechanism 40, the tape feeding mechanism 50, the cutting mechanism 60, the tape feeding outlet 70, the tape suction mechanism 81, the tape folding means 90, and other components. In this embodiment, the main body 20 uses a resin material, and an operation panel is installed on the upper cutting mechanism side. The operation panel is electrically connected to a control board (not shown), and is electrically connected so that the drive mechanism 30, the tape feeding mechanism 50, and the cutting mechanism 60 can be controlled from the board.

  The drive mechanism 30 is installed in the main body 20 of the electric tape cutter and includes a drive source (not shown) connected to a power supply source and a gear 54 for transmitting power. The driving source (not shown) uses a motor in this embodiment. The motor is supplied with electric power from an electric power supply source, and transmits power to the gear of the tape feeding mechanism 50 by a gear. In this embodiment, electric power is externally used as a power supply source (not shown).

The tape holding mechanism 40 is a mechanism for holding a roll-shaped adhesive tape 42 coated with an adhesive on the back surface. In this embodiment, the roll-shaped adhesive tape 42 wound around an annular reel is used as a holding portion. It is the structure fitted so that it could rotate with the reel.
The adhesive tape 42 is a tape in which an adhesive material is applied only to one side serving as a back surface. In this embodiment, a tape having a tape width of about 20 mm is used. However, there is no limitation on the width of the tape, and the width of the tape can be freely selected.
The non-adhesive bonding surface 44 formed on the pressure-sensitive adhesive tape 42 is a tab-shaped tape picking part formed by bonding the adhesive surfaces to the tip of the pressure-sensitive adhesive tape 42 with a certain length, and the adhesive surface on the back surface is folded back. Since the back surfaces (bonded surfaces) are joined in a state where they are in contact with each other, even if there is something that touches others, they will not be bonded. The non-adhesive part can be used for lifting the tape as an ear or a pick part, whereby the tape in a state of being bonded very easily can be lifted from the pick part to peel the entire tape.

  The tape feeding mechanism 50 includes a feeding roller 52 and a gear 54. The feed roller 52 may be a single roller, but it is possible to send the adhesive tape 42 to the tape suction mechanism 81, the tape folding means 90, and the cutting mechanism 60 in the absence of bending, and In order to prevent the adhesive tape 42 from slipping and to reliably deliver the adhesive tape 42, a configuration in which a plurality of adhesive tapes 42 are installed is desirable. For example, a small roller that holds a large roller and presses the tape from the top is installed, and a medium roller that works in conjunction with the large roller is installed, and the transfer roller is placed above the medium roller to reliably transfer the tape from the large roller to the medium roller. It is possible to consider a configuration in which

The feed roller 52 is formed of a cylindrical rotating body, and has a configuration in which the adhesive tape 42 does not adhere to the roller 52 more than necessary by forming a plurality of grooves in the direction perpendicular to the shaft on the surface of the roller. An embodiment is conceivable.
The adhesive tape 42 meanders manually or by using an elastic body such as rubber to narrow the width of the side wall provided in parallel to the tape in accordance with the width of the adhesive tape 42. You may install the tape adjustment mechanism which prevents this in the arbitrary places of a tape feed mechanism.

The tape support roller 56 is a guide roller that supports the adhesive tape 42 so that the non-adhesive bonding surface 44 is formed on the tape fed from the tape feeding mechanism 50 and then fed to the cutting mechanism 60 with certainty. The pressure-sensitive adhesive tape 42 on which the non-adhesive bonding surface 44 is formed may hang down due to its own weight before being sent to the cutting mechanism 60. Therefore, the tape support roller 56 is provided between the cutting mechanism 60 and the tape feeding mechanism 50 so that the adhesive tape 42 formed with the non-adhesive bonding surface 44 is reliably fed to the cutting mechanism 60 without adhering to the other. Installed.
With the structure in which the tape support roller 56 is driven, the adhesive tape 42 on which the non-adhesive bonding surface 44 is formed can be stably sent out to the cutting mechanism 60. As the driving force, a structure that rotates using the power transmitted from the driving mechanism 30 is conceivable. However, the driving force is a structure that obtains power by a motor or the like installed at an arbitrary position independently of the driving mechanism 30. Also good.

The cutting mechanism 60 is equipped with a cutting blade that cuts the adhesive tape 42. The adhesive tape 42 on which the non-adhesive bonding surface 44 is formed by the tape folding means 90 is delivered to the cutting mechanism 60.
The cutting mechanism 60 of this embodiment is equipped with cutting blades on the upper side and lower side, the upper cutting blade is fixed, and the lower cutting blade is the control board (see FIG. The adhesive tape 42 is cut by being moved while being controlled by (not shown).

  The tape delivery port 70 is an opening through which the adhesive tape 42 that has been cut by forming the non-adhesive bonding surface 44 is delivered. The width of the tape delivery port 70 is desirably an opening having a width that exceeds the width of the adhesive tape 42 that is held by the tape holding mechanism 40 and can be fed by the tape feeding mechanism 50. Since a finger of a hand enters the cutting mechanism 60 through the tape delivery port 70 and may be injured, an embodiment equipped with a cover or a safety device that prevents the fingers from entering the cutting mechanism 60 is desirable.

  The tape fixing means 80 is configured to suck and fix the adhesive tape 42 delivered from the tape feeding mechanism 50 by the tape suction mechanism 81. When the adhesive tape 42 is sent with the adhesive surface as the back facing downward, the adhesive tape 42 hangs down due to its own weight, so there is a possibility that it will be bonded (attached) to the cutting blade of the tape cutter. If even a part of the adhesive tape is affixed to this part, there is a problem that it is impossible to fold back and form the non-adhesive bonding surface 44 at the tip of the adhesive tape 42. In order to avoid this, a tape fixing means 80 for lifting and fixing the adhesive tape 42 delivered from the tape feeding mechanism 50 upward is provided. In this embodiment, a tape suction mechanism 81 for adsorbing the tape upward is provided as the tape fixing means 80, so that the tape does not hang down due to its own weight.

The tape suction mechanism 81 sucks air from the suction port 82, and by the suction force, the surface of the adhesive tape 42 located below the suction port 82 is sucked and floated, and the other adhesive surface is the back surface. Fix it so that it does not touch. As a result, a space is formed below the adhesive tape 42 fed from the tape feeding mechanism 50, so that the non-adhesive bonding surface 44 can be easily formed by the operation of the tape folding means 90.
The suction port 82 of the tape suction mechanism 81 that is a means for adsorbing and fixing is installed inside the tape delivery port 70 that feeds the tip portion of the adhesive tape 42 and above the adhesive tape 42. The suction port 82 is preferably installed in the vicinity of the tape folding means 90.
The suction pump 84 has a structure for sucking air from the suction port 82. In this embodiment, an electric suction pump is used.

The tape folding means 90 is a folding means that folds the tip portion of the adhesive tape 42 fixed by the tape fixing means 80 for fixing the adhesive tape 42 in the direction of the adhesive surface with a certain width. As a result, it is possible to form a non-adhesive bonding surface 44 in which the bonding surfaces are bonded to each other at a certain length at the tip of the adhesive tape 42.
The flap 92 is a member that folds the adhesive tape 42 sucked and fixed by the tape suction mechanism 81 at a fixed position from the cut portion.
The flap rotation motor 94 is an electric motor that gives rotational power to the flap 92. The flap 92 is rotatably installed, and a rotational force is transmitted from the flap rotation motor 94 via a drive gear (not shown). In a state where the adhesive tape 42 is adsorbed and fixed by the tape suction mechanism 81, the flap 92 is rotated about 180 degrees to the adhesive surface side of the adhesive tape 42 so that the adhesive tape 42 is folded, and the adhesive surfaces are adhered to each other for non-adhesive joining. A surface 44 is formed.

  The tape folding means 90 forms the non-adhesive bonding surface 44 by performing the folding process of the adhesive tape 42 after the adhesive tape 42 delivered by the tape feeding mechanism 50 is cut by the cutting mechanism 60. At this time, the adhesive surfaces which are the back surfaces of the adhesive tape 42 are pressed together to form a non-adhesive bonding surface 44 that is difficult to peel off. Therefore, after the tape is folded, until the adhesive tape 42 is next delivered. The flap 92 rotated about 180 degrees holds the state where the adhesive tape 42 is pressed. When the adhesive tape 42 is instructed to be sent, the flap 92 is reversed by about 180 degrees and returned to the original position, so that the adhesive tape 42 can be smoothly delivered.

The tape anti-floating member 96 is attached to the tip of the flap 92 and prevents the adhesive tape 42 from floating. Since the folding operation by the flap 92 is performed at a high speed, the adhesive tape 42 is not displaced during the rotating operation without hindering the formation of the non-adhesive bonding surface 44.
Various materials can be used for the anti-floating member 96 of the tape. In the embodiment, rubber is used as the material. However, any material having the frictional force capable of preventing the adhesive tape 42 from slipping can be used. It is not limited to.

Hereinafter, a series of operations of the electric tape cutter of the present invention will be described.
(1) The adhesive tape 42 is adsorbed and fixed by the tape suction mechanism 81, and then the non-adhesive bonding surface 44 is formed by the tape folding means 90. At this time, since the flap 92 rotates about 180 degrees and presses the folded adhesive tape 42 and keeps pressing until the next delivery instruction is given, the non-adhesive bonding surface 44 that is sufficiently pressed against each other and difficult to peel off is formed. It is formed and enters a standby state.
(2) When there is a delivery instruction, the adhesive tape 42 on which the non-adhesive bonding surface 44 is formed is conveyed to the cutting mechanism 60 via the tape support roller 56. At the same time, the adhesive tape 42 held by the tape holding mechanism 40 is carried to the tape suction mechanism 81 via the tape feeding mechanism 50.
(3) The pressure-sensitive adhesive tape 42 on which the non-adhesive bonding surface 44 is formed is cut by the cutting mechanism 60 and then taken out from the tape delivery port 70 to be ready for supply.
(4) Thereafter, the process returns to the above (1), and the processing is repeated thereafter.
