Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cutter device for automatically feeding an adhesive tape from a tape roll body wound in a roll shape.

[0002]

2. Description of the Related Art Conventionally, a tape roll body obtained by winding an adhesive tape in a roll shape is fitted in a tape holder, which is rotatably attached to a case, and an adhesive tape is pulled out from a cutting blade attached to the case. There is disclosed a tape cutter in which a case is provided with a scale for measuring the length of the adhesive tape along the line (Actual Kaihei 2-22968).
With this tape cutter, by measuring the length of the adhesive tape pulled out from the tape roll body with a scale,
The adhesive tape of the required length can be easily obtained. However, the conventional tape cutter described above has a relatively troublesome problem in that the feeding length of the adhesive tape must be manually adjusted. Further, in the above-described conventional tape cutter, when the adhesive tape is pulled out from the tape roll body, a relatively large force is required due to the adhesive force of the adhesive tape, so that the tape cutter itself does not move.
It is as heavy as 00g-1kg. Therefore, it was inconvenient to handle.

In order to solve these problems, as shown in FIGS. 4 and 5, a tape holder 4 fitted with a tape roll body 2 is rotatably attached to a case 1 and fed out from the tape roll body 2. A cutting blade 6 for cutting the adhered adhesive tape 2a is attached to the case 1 at a predetermined distance from the tape holder 4, and the adhesive surface side roller 8 and the non-adhesive side roller 8 which are pressed against each other by sandwiching the adhesive tape 2a from both sides thereof. There is known an electric tape cutter rotatably attached to the case 1 such that a rotary roller 7 having a surface side roller 9 is located near the cutting edge 6.

The adhesive surface side roller 8 is composed of a first roller 8 and a second roller 8.
a and 8b, the first and second rollers 8a and 8b have a plurality of knurls formed on the outer peripheral surface thereof and a plurality of first and second discs 8c arranged at predetermined intervals in the axial direction. 8
d respectively. The first and second rollers 8a and 8b are arranged so that the plurality of first and second discs 8c and 8d are inserted between the plurality of second and first discs 8d and 8c. Further, the non-adhesive surface side roller 9 is pressed against the second roller 8b obliquely from above by a spring (not shown), and the second disc 8d is pressed.
It has two thin disks 9a inserted between them. The non-adhesive surface side roller 9 is configured to be movable upwards against the elastic force of the spring. The cutting blade 6 is provided so as to project from between the first roller 8a and the non-adhesive surface side roller 9 toward substantially the center of the second roller 8b, and a saw-toothed blade edge is formed at the lower end thereof.

The first and second rollers 8a and 8b are driven by a driving means (not shown), and the driving means is operated by a push button switch (not shown) mounted on the outer surface of the case 1. Further, a cutting sensor (not shown) for detecting the upward movement of the non-adhesive surface side roller 9 is provided in the case 1, and a three-stage switch (not shown) is attached to the outer surface of the case 1. . A controller (not shown) is built in the case 1, and the controller controls the drive means based on the detection outputs of the disconnection switch and the three-stage changeover switch.

In the electric tape cutter configured as described above, the end portion of the adhesive tape 2a pulled out from the tape roll body 2 is attached to the upper portion of the outer peripheral surface of the first roller 8a by the adhesive, and in this state, the push button switch is pressed. When is pressed, the first roller 8a rotates in the direction of the solid arrow and the second roller 8b
Rotates in the direction of the dashed arrow, the end of the adhesive tape 2a is affixed to the upper part of the outer peripheral surface of the second roller 8b, and further passes between the second roller 8b and the non-adhesive surface side roller 9 and is delivered to the outside of the case 1. To be done. When the three-stage changeover switch is set to a desired position and the adhesive tape 2a fed out of the case 1 is pulled up and cut by the cutting edge 6, the controller drives the driving means to set the three-stage changeover switch. The adhesive tape 2a is automatically fed out for a predetermined length. As a result, the work of pulling out the adhesive tape 2a from the tape roll body 2 becomes unnecessary, and therefore the electric tape cutter itself does not have to be made heavy.

[0007]

However, in the above-mentioned conventional electric tape cutter, knurls are formed on the outer peripheral surfaces of the first and second discs of the first and second rollers, and the first and second rollers are formed. Since the two discs are arranged at predetermined intervals, the knurls and the streaks 3a, 3b (the outer peripheral edges of the first and second discs) are formed on the adhesive surface of the adhesive tape fed from the rotating roller. There was a problem that (Fig. 5) occurred. As a result, when the adhesive tape is transparent, there is a problem that when the cut adhesive tape is attached to a predetermined place, white lines are visible and the appearance is impaired. Further, in the above-mentioned conventional electric tape cutter, since the thin disc of the non-adhesive surface side roller is inserted between the second discs of the second roller, wrinkles occur in the adhesive tape, the knurled eye or the first disc. 1
Also, there is a problem that white streaks are further clearly generated due to the outer peripheral edge of the second disc.

A first object of the present invention is that the adhesive surface of the adhesive tape is not contaminated and wrinkles do not occur on the adhesive tape, and the adhesive tape can be smoothly delivered toward the cutting edge, and the tape roll body can be replaced. An object of the present invention is to provide a tape cutter device for automatically feeding out an adhesive tape, which can perform a simple operation in a short time. A second object of the present invention is that an adhesive tape does not get entangled when the end portion of the adhesive tape is attached to a cutting edge and the adhesive tape does not get entangled, and an operation of paying out the adhesive tape from a tape roll body is unnecessary. It is to provide a tape cutter device for automatically feeding the tape. A third object of the present invention is that the adhesive tape does not wind around the second adhesive surface side roller, the finger tip of the cutting blade does not touch the finger, and the adhesive of a required length is simply operated by operating the feeding switch. An object of the present invention is to provide a tape cutter device that can automatically dispense an adhesive tape, which can dispense the tape.

Connected to. 46 is a battery (FIGS. 1 and 2).

The method of use and the operation of the tape cutter device thus configured will be described. When setting the tape roll body 12 in the tape cutter device 10, first, the lid 11
b in the direction of the solid line arrow in FIG.
The opening (not shown) is opened, the tape holder 14 is taken out in this state, the tape roll body 12 is fitted therein, and then the tape roll body 12 is housed in the case body 11a again. Then, the end portion of the adhesive tape 12a is pulled out from the tape roll body 12 to the outside of the case body 11a from the feeding port 11c via the respective upper surfaces of the first adhesive surface side roller 21a, the second adhesive surface side roller 22a and the blade edge guard member 23. , The lid 11b is rotated in the direction of the dashed arrow to close the opening of the case body 11a. With such a simple operation, the tape roll body 12 can be set in the tape cutter device 10 in a short time.

Next, when the timer switch 38 is set to a desired time and the adhesive tape 12a drawn out of the case 11 is pulled down in the direction of the solid line arrow in FIG. 1, the second adhesive surface side roller 22a causes the compression coil spring. Descending against the elastic force of 26,
Moreover, since the cutting edge guard member 23 is elastically deformed to expose the cutting edge of the cutting edge 16, the adhesive tape 12a is smoothly cut by the sharp cutting edge 16. At this time, the compression coil spring 2
Since 6 and the blade edge guard member 23 are deformed with a relatively small force, the adhesive tape 12a can be cut without pressing the case 11. Further, since the cutting edge guard member 23 is formed of silicone rubber having weak adhesiveness, the cut adhesive tape 12a can be smoothly peeled off from the cutting edge guard member 23. When the cutting of the adhesive tape 12a is completed, the second adhesive surface side roller 22a rises by the elastic force of the compression coil spring 26 and pushes up the adhesive tape 12a, so the end portion of the adhesive tape 12a pulled out from the tape roll body 12 Is separated from the cutting edge of the cutting blade 16 and elastically deformed, the cutting edge guard member 2
Since 3 returns to cover the outer surface of the cutting edge of the cutting blade 16, even if the finger is inserted from the feeding port 11c, the finger does not touch the cutting edge.

When the adhesive tape 12a is cut, the controller 44 detects that the contact point of the cutting sensor 39 is closed due to the lowering of the second adhesive surface side roller 22a, and when the cutting is completed, the second adhesive surface side roller 22a is raised. Disconnection sensor 3
When it is detected that the contacts 9 are opened, the electric motor 29 is operated for the time set by the timer switch 38. When the electric motor 29 operates, the first and second adhesive surface side rollers 21a and 22a respectively rotate in the directions of solid arrows, and the adhesive tape 12a is drawn out from the payout opening 11c, and after a lapse of a predetermined time, the controller 44 causes the electric motor 2 to move.
Stop 9. At this time, the outer peripheral surfaces of the first and second adhesive surface side rollers 21a and 22a are formed of silicone rubber having a weak adhesive property, and the outer diameters of the first and second non-adhesive surface side rollers 21b and 22b are the first and second Second adhesive side roller 2
Since the outer diameters of the adhesive tapes 12a are smaller than the outer diameters of 1a and 22a, the adhesive tape 12a is composed of the first and second non-adhesive surface side rollers 21.
The first and second adhesive surface side rollers 2 are warped toward b and 22b.
It does not wind around 1a and 22a. As a result, the adhesive tape 12a is automatically fed out by a predetermined length.

Further, since the entire surfaces of both sides of the adhesive tape 12a are sandwiched by the rotating rollers 17, the adhesive tape 12a
Streaks occur on the adhesive surface of a, or the adhesive tape 12
Wrinkles do not occur on a. If an extremely long adhesive tape 12a is required, the controller 44
Since the electric motor 29 is operated only while the feeding switch 43 is turned on, it is sufficient to continue to push the feeding switch 43 until the adhesive tape 12a is fed to a desired length. Further, in the present invention, the adhesive tape 12a fed out of the case 11 is compared with a conventional electric tape cutter in which the case is pushed by hand at the time of cutting by pulling up the adhesive tape or the case is lifted unless a weight is provided in the case. Since it can be cut by pulling down, the case 11 does not lift and the weight of the tape cutter device 10 can be reduced.

In the above embodiment, the first and second adhesive side rollers are constituted by fitting the silicone rubber tube to the outer peripheral surface of the resin roller body, but the outer periphery of the resin roller body Alternatively, a tube formed of urethane rubber or other rubber having a weak adhesive property may be fitted on the surface. Further, the entire first and second adhesive surface side rollers may be formed of silicone rubber, urethane rubber, silicone resin, urethane resin, fluororesin or other rubber or resin having weak adhesion. Further, although the blade guard member is formed of silicone rubber in the above embodiment, urethane rubber or other rubber may be used as long as it is a rubber having a weak adhesive property and an elastic force.

Further, in the above embodiment, the outer diameter of the second non-adhesive surface side roller is set to 1/2 of the outer diameter of the second adhesive surface side roller, but this is an example, and the second non-adhesive surface side roller is an example. The outer diameter may be less than 1/2 of the outer diameter of the second adhesive surface side roller.
Also, the outer diameter of the first non-adhesive surface side roller is set to 1/2 of the outer diameter of the first adhesive surface side roller, but the outer diameter of the first non-adhesive surface side roller is smaller than the outer diameter of the first adhesive surface side roller. It may be less than 1/2. Further, in the above embodiment, the compression coil spring is used as the spring for pressing the second adhesive surface side roller to the second non-adhesive surface side roller, but a leaf spring, a tension coil spring or other spring may be used. Further, in the above embodiment, the cutting blade having a straight-lined cutting edge slightly inclined from the horizontal plane is mentioned, but the cutting edge having a straight-lined cutting edge extending horizontally is not limited to this, or a cutting edge having a saw-shaped cutting edge. You can use a blade.

[0024]

As described above, according to the present invention, at least the outer periphery of the roller on the adhesive surface side of the rotary roller that pulls out the adhesive tape from the tape roll body and sends it out toward the cutting edge is pressed against the adhesive tape. Since the surface is formed of rubber or resin having weak adhesiveness, the adhesive tape can be quickly peeled off from the adhesive surface side roller, and the adhesive tape can be smoothly delivered toward the cutting edge. As a result, the adhesive surface of the fed adhesive tape is not contaminated and wrinkles do not occur on the adhesive tape. In addition, an opening is formed on the upper surface of the case body, the opening is closed so that the lid can be opened, the adhesive side roller is rotatably attached to the case body, and the non-adhesive side roller is rotatably attached to the lid. Further, if the non-adhesive surface side roller and the adhesive surface side roller are configured to be in pressure contact with each other with the lid closed at the opening, the tape roll body can be replaced by a simple operation in a short time.

The rotating roller has a pull-out roller having a first adhesive surface side roller and a first non-adhesive surface side roller, and a second roller.
And a second non-adhesive surface side roller, and a delivery roller for delivering the adhesive tape so as to pass through a position separated by a predetermined distance from the cutting edge of the cutting blade. If the spring is urged to press against the second non-adhesive surface side roller, the second adhesive surface side roller is pressed against the second non-adhesive surface side roller by the elastic force of the spring when the cutting of the adhesive tape by the cutting blade is completed. In addition, since the end portion of the adhesive tape is separated from the cutting blade, the adhesive tape is not entangled by being fed out with the end portion of the adhesive tape attached to the cutting blade. Further, if the controller controls the driving means based on each detection output of the timer switch that adjusts the operating time of the driving means and the cutting sensor that detects that the adhesive tape has been cut by the cutting blade, Each time the adhesive tape is cut, the adhesive tape is fed out by a predetermined length, so that the work of feeding out the adhesive tape from the tape roll body becomes unnecessary.

If a cutting edge guard member having a weak adhesive force and having elastic force is provided adjacent to the cutting blade and protruding from the cutting edge of the cutting blade by a predetermined length, the cutting edge guard member is cut when the adhesive tape is cut by the cutting blade. Since the cutting edge is exposed by elastic deformation and the cutting edge guard member returns when the cutting of the adhesive tape by the cutting edge is completed, the outer surface of the cutting edge of the cutting edge is covered by the cutting edge guard member, and the finger does not touch the cutting edge. Also,
If the outer diameter of the second non-adhesive surface side roller is 1/2 or less of the outer diameter of the second adhesive surface side roller, the adhesive tape warps toward the second non-adhesive surface side roller. 2 It does not wrap around the adhesive side roller. Further, if the feeding switch is attached to the outer surface of the case and the driving means is operated only while the feeding switch is turned on, the adhesive tape having the required length can be fed only by operating the feeding switch. . Furthermore, if the cutting edge of the cutting blade is directed upward, it can be cut by pulling down the adhesive tape fed out of the case, so that the case does not lift and the weight of the tape cutter device can be reduced.
