Description

The present invention relates to an apparatus for quantitatively cutting an adhesive tape that can be attached to a tape cutter body.

  In order to use an adhesive tape such as a cellophane tape for sealing an envelope, a predetermined tape length corresponding to the width dimension (9 cm, 12 cm) of the envelope is required. However, a relatively large tape cutter used in the state of being placed on a table provided in the past, picks the tip of the tape and pulls it out to the desired amount, and guides the tape to the cutting blade formed on the tape cutter body. Since the tape is cut to an appropriate length by pressing, it is difficult to accurately cut the tape to the required length. That is, with existing tape cutters, the cut tape may be too long or too short, and cannot be used for cutting a tape with a desired fixed dimension.

For this reason, for example, Patent Document 1 provides a tape cutter in which a cylinder is disposed between a tape reel and a cutting blade. This is because when the tape is pulled out, the rotation distance of the cylinder that rotates due to friction with the non-adhesive surface of the tape that is in contact with the cylindrical surface is measured by a counter provided in the cylinder. Is measured, and a fixed tape length is quantitatively cut. Further, in Patent Document 1, the above-mentioned counter can be inserted by fixing the holder to the inner wall of the tape storage chamber between the tape reel and the cutting blade in the tape cutter body with double-sided tape or the like. The structure can be attached to the main body.
Patent Document 2 describes a tape cutter in which a cylinder is disposed in contact with a tape bonding surface between a tape reel and a cutting blade. Patent Document 3 describes a tape cutter with a counter having a tape reel and a stopper that stops at a predetermined tape length.

However, in any of the above-described Patent Documents 1 to 3, the obtained tape length does not necessarily match the desired length.
That is, in the invention described in Patent Document 1, depending on how the tape is taken up from the cutting blade and the cylindrical surface, there is a gap between the tape and the cylindrical surface, or there is slip between them. In some cases, the cylinder may not rotate by the length of the drawn tape. In addition, since the length of the drawn tape is measured between the tape reel and the cutting blade, the distance between the cellophane tape reel and the cutting blade may vary depending on the shape and type of the tape cutter body to which the counter is attached. Since it is short, the size of the cylinder in the counter is limited, and the degree of freedom in design is poor. Of course, it is difficult to measure the rotational distance of the cylinder in millimeters and display it on the counter. Therefore, in the invention described in Patent Document 1, the tape length cannot be cut by a length in millimeters, and the desired length may not match the cut tape length.
Further, in the invention described in Patent Document 2, since the tape length is calculated by calculating the length of the tape that has been pulled out by bringing the adhesive surface of the tape to be in contact with the cylindrical surface, depending on the direction in which the tape is pulled out. Since the adhesive surface of the tape does not come into contact with the cylindrical surface, there is a possibility that the length of the drawn tape cannot be measured. In the invention described in Patent Document 3, since the tape length is measured based on the rotation distance of the reel located inside the tape, it is impossible to accurately cut a tape having a desired fixed dimension.

  Therefore, the present invention has been made to solve such a problem, and the length of the drawn adhesive tape can be accurately measured, and there is an error between the desired cutting tape length and the cut adhesive tape length. An object of the present invention is to provide an apparatus for quantitatively cutting a small amount of adhesive tape.

The quantitative cutting device for an adhesive tape according to the invention of claim 1 is brought into contact with the outer peripheral surface of the adhesive tape formed by attaching an adhesive on one side and wound, and rotates around in accordance with the drawing distance of the adhesive tape. A tape through a rotating roller provided with an anti-slip material and having a scale around the periphery, a supporting shaft portion that rotatably supports the rotating roller, and a support member that holds the supporting shaft portion An attachment portion for attaching the rotating roller to the cutter body is provided, and an elastic force is applied to the central axis direction of the adhesive tape by the elastic force applying member, and the measurement is performed. The length of the drawn adhesive tape is measured with a pointer that indicates the scale of the rotating roller according to the rotation distance of the rotating roller.

By the way, the rotation roller having the anti-slip material has an outer peripheral surface made of elastomer, rubber, or plastic, and a material having high contact resistance can be used. In particular, it is common to use a rotating roller that is approximately equal to the tape width, but it does not require that the rotating roller be strictly equal. There is no problem even if it is wide or narrow.
Further, the relationship between the anti-slip material and the scale formed around the rotating roller only needs to make the anti-slip material transparent and confirm the scale formed around the rotating roller. And you may form with a color different from a scale with a colored non-slip prevention material.
In addition, the adhesive tape formed by applying an adhesive on one side and winding is usually a tape obtained by winding an elongated strip-shaped cellophane tape having an adhesive layer formed on one side in an annular shape.

As the attachment portion, the rotating roller is attached to the tape cutter body, and attachment portions such as clip-like fasteners or adhesives, double-sided adhesive tapes, screw stops, etc. can be employed to facilitate separation. Any of these may be selected, but it is desirable to use attachment means that stabilizes the mechanical attachment state as much as possible.

And the said elastic-force provision member gives an elastic force to the said adhesive tape side of the said rotation roller, and should just be a grade without slipping between both. It is preferable that an arrangement is provided in which an elastic force that biases the central axis of the rotating roller is applied to the central axis direction of the adhesive tape. However, this does not strictly require the central axis of the rotating roller to be biased with respect to the central axis direction of the adhesive tape, and the rotation around the adhesive tape is mechanically stable. Any device that can contact the periphery of the roller may be used. However, it is only necessary that the rotating roller is not lifted together with the adhesive tape when the adhesive tape is pulled out so that the drawing from the adhesive tape does not affect the contact between the two.

Further, the measuring unit rotates in conjunction with the rotation of the adhesive tape and measures the length of the tape drawn out by the rotational distance of the adhesive tape, and the rotating roller may be directly scaled. It is also possible to input the rotation of the rotating roller to a digital counter.
Furthermore, when the adhesive tape is not cut quantitatively, if it is attached to the tape cutter main body and resists the elastic force of the elastic force imparting member and is moved backward through the dead point, it is elastic at that position. It can be stopped by receiving the elastic force of the force applying member. That is, the use of the measurement function can be stopped while being attached to the tape cutter body.
The adhesive tape quantitative cutting device referred to in the present invention can be attached to the tape cutter main body, or can be configured as the tape cutter main body itself. That is, the mounting portion can be directly disposed on the tape cutter body.

The measuring unit of the adhesive tape quantitative cutting device according to the invention of claim 2 is provided for a disc having a gear having a fixed relationship with the scale of the rotating roller, and a gear around the disc. And a measurement auxiliary part having a spring that allows its rotation in the elastic contact state, and the measurement auxiliary part generates a sound in accordance with a pull-out distance of the adhesive tape.
The measurement assisting unit only needs to estimate the length of the adhesive tape drawn by the sound and the rhythm as the rotating roller rotates, and does not accurately determine the length by the sound and the rhythm. The disk on which the gear is formed needs a peripheral gear, and may be any one that generates sound by elastic contact with the gear. In particular, the teeth are preferably teeth that allow one rotation and prohibit the opposite rotation.

The measurement auxiliary part of the measuring unit of the quantitative tape cutting device according to the invention of claim 3 rotates integrally with the rotating roller, and gives a response to the puller side according to the length of the drawn adhesive tape. is there.
Responding to the puller side in accordance with the length of the drawn adhesive tape means that there is a change in the load, and the change in the load has only to have a predetermined relationship with the rotation distance of the rotating roller.

According to a fourth aspect of the present invention, there is provided a quantitative cutting apparatus for adhesive tape in which the circumference of the rotating roller is any one of 5 cm, 9 cm, 10 cm, 12 cm, 15 cm, and 20 cm. Depending on the intended use, for example, a standard mail can be sealed with 9 cm, and a non-standard mail can be sealed with 12 cm, so that it is possible to measure the length according to the purpose of use.

  The anti-slip material of the rotary roller of the adhesive tape quantitative cutting device according to the invention of claim 5 is made of an elastomer. However, when the present invention is carried out, it is sufficient if the contact resistance is high and the friction surface of the rotating roller and the adhesive tape is difficult to slip, and it can be formed from rubber or plastic.

  The measurement auxiliary section of the measuring section of the adhesive tape quantitative cutting apparatus according to the invention of claim 6 is detachable from the rotating roller and can be assembled. Here, the measurement auxiliary part of the measurement part can be formed integrally with the rotary roller, but various combinations are possible by making it separate.

According to a first aspect of the present invention, there is provided a quantitative cutting apparatus for an adhesive tape, wherein the adhesive tape is brought into contact with an outer peripheral surface of an adhesive tape formed by winding an adhesive on one side and is slipped about to rotate according to a pull-out distance of the adhesive tape. A stopper is disposed on the tape cutter main body via a support shaft that rotatably supports a rotating roller that is provided with a stop prevention material and that has a scale around the periphery, and a support member that holds the support shaft, and The adhesive pulled out by the rotational distance of the rotating roller that applies an elastic force that urges the central axis of the rotating roller relative to the direction of the central axis of the adhesive tape and rotates according to the pulling distance of the adhesive tape. The tape length is measured by a pointer indicating the scale of the rotating roller.
Accordingly, the length of the tape drawn by picking the tip of the adhesive tape can measure the distance drawn by the adhesive tape by measuring the rotational distance of the rotating roller. In this way, since the length of the drawn adhesive tape can be measured, by pulling out the adhesive tape by itself to the cutting blade formed on the tape cutter body when the desired fixed-size adhesive tape is pulled out, A desired fixed dimension of adhesive tape can be cut.

Further, since the rotating roller can come into contact with the adhesive tape by its own weight, the rotating roller is given an elastic force that biases the central axis of the rotating roller with respect to the central axis direction of the adhesive tape. Therefore, even if the outer diameter of the adhesive tape changes due to consumption of the adhesive tape, the outer peripheral surface of the rotating roller can always be brought into close contact with the outer peripheral surface of the adhesive tape, and accurate measurement can be performed.
And since the rotating roller contacts the non-adhesive surface of the adhesive tape, and the rotating roller has an outer peripheral surface made of an anti-slip material, the contact resistance between the rotating roller and the adhesive tape is high, The friction surface is not slippery and accurate measurement is possible.
Therefore, the rotating roller is always pressed against the adhesive tape, and the adhesive tape and the outer peripheral surface of the rotating roller are accurately moved by frictional conduction due to a constant contact pressure. Since the rotating roller rotates by the distance of the rotation, the length of the drawn adhesive tape can be accurately measured by measuring the rotating distance of the rotating roller.

Further, the length of the drawn adhesive tape is measured by the rotation distance of the rotating roller that is brought into contact with the adhesive tape. Usually, in a tape cutter in which an adhesive tape such as a cellophane tape is rotatably held. Since the outer peripheral surface of the adhesive tape that contacts the rotating roller is exposed, the size (diameter) of the rotating roller that contacts the outer peripheral surface of the upper half of the adhesive tape is not limited, High design freedom.
That is, since the size of the rotating roller can be freely set, for example, the rotating distance of the rotating roller can be measured in millimeter units using a large rotating roller.
Furthermore, switching between normal cutting and quantitative cutting can be facilitated by selecting the mounting portion.
In this way, by accurately measuring the length of the drawn adhesive tape, it is possible to provide an adhesive tape quantitative cutting device with less error between the desired length and the cut tape length.

According to a second aspect of the adhesive tape quantitative cutting device of the present invention, the measurement auxiliary section generates a sound in accordance with the pull-out distance of the adhesive tape. Therefore, in addition to the effect of the first aspect, by measuring the number of generated sounds, the distance drawn by the adhesive tape can be measured. The length of the tape drawn by picking the tip of the adhesive tape can assist the measurement of the length of the drawn tape by measuring the number of generated sounds.

The tape quantitative cutting device according to the invention of claim 3 rotates integrally with the rotating roller and gives a response to the puller side according to the length of the drawn adhesive tape. In addition to the above effect, the length of the pulled-out tape can be measured by obtaining the rhythm of the drawer by measuring the number of feeling this response.

In the adhesive tape quantitative cutting device according to the invention of claim 4, the circumference thereof is any one of 5 cm, 9 cm, 10 cm, 12 cm, 15 cm, and 20 cm. In addition to the effect described in any one of the above, it is possible to select an optimal rotating roller that is suitable for quantitative cutting of an adhesive tape having a desired fixed dimension that meets the purpose.

In the apparatus for quantitatively cutting an adhesive tape according to a fifth aspect of the present invention, since the anti-slip material of the roller is made of an elastomer, the contact resistance between the rotating roller and the adhesive tape is high, and the friction surface is difficult to slip. Therefore, in addition to the effect described in any one of claims 1 to 4, the outer peripheral surface of the adhesive tape and the rotating roller moves, and the rotating roller is surely secured by a distance that the adhesive tape rotates. Therefore, the length of the drawn-out adhesive tape can be measured more accurately.

Since the quantitative cutting device for adhesive tape of the invention of claim 6 is such that the measurement auxiliary part of the measurement part is detached from the rotating roller and can be assembled, it can be assembled as described in any one of claims 1 to 5. In addition to the effects described above, it is possible to select an optimum rotating roller and a measurement auxiliary unit that are suitable for quantitative cutting of a desired fixed-size adhesive tape that is most easily used and that matches the purpose.

In the embodiments, the same symbols and the same reference numerals mean the same or corresponding functional parts, and the same symbols and the same reference numerals are the functional parts common to those embodiments. The detailed description to be omitted is omitted.
First, the tape quantitative cutting apparatus of the present embodiment will be described with reference to FIGS.

FIG. 2A is a front view of the main part of the rotating roller, the measurement auxiliary unit, and the pointer of the adhesive tape quantitative cutting device according to the embodiment of the present invention, and FIG. 2B is the rotation roller and the measuring auxiliary unit.

FIG. 5 is an overall perspective view showing a state where the adhesive tape quantitative cutting device according to the embodiment of the present invention is attached to the tape cutter body.

In the figure, a scale 13 is provided at regular intervals on the outer peripheral surface 2 of the rotating roller 1 whose main body is formed in a bottomed cylindrical shape, and a support shaft is provided at one end (the left side surface in the drawing) of the rotating roller 1. A disk 11 having teeth 12 formed around the same axis as that of 26 is disposed. As shown in FIG. 2 (c), the disk 11 is joined to the left side surface on the opening side of the main body of the rotating roller 1, and the disk 11 and the rotating roller 1 are assembled together and rotated. The disk 11 also rotates integrally with the rotation of the roller 1. The rotating roller 1 and the disk 11 are rotatably mounted about the support shaft 26, and a pair of supporting members 21 (a supporting member 21a or a supporting member 21b on the side surfaces of the rotating roller 1 and the disk 11) ( In the case of a common expression that does not specify the right support member 21a or the left support member 21b, it is simply supported by the support member 21). One end of the support shaft 26 is fixed to the pair of support members 21 with a nut 27.

The rotating roller 1 has an outer peripheral surface 2 made of an elastomer 3. When the outer peripheral surface 2 (friction surface) of the rotating roller 1 rotates in conjunction with the rotation of the adhesive tape 42, the contact resistance is adjusted so that the outer peripheral surface 2 of the rotating roller 1 rotates in synchronization with the drawn-out adhesive tape 42. Any material can be used as long as it has a high anti-slip effect. For example, materials such as rubber, silicon, and plastic having a large coefficient of friction can be used in addition to a polymer material exhibiting elasticity such as an elastomer. In addition, since the outer peripheral surface 2 of the rotating roller 1 is in contact with the outer peripheral surface 42a of the adhesive tape 42, it is desirable to make it a smooth surface so as not to damage the adhesive tape 42. In particular, the elastomer 3 is suitable for these conditions.

One end of the pointer 15 is fixed to the front end of the support member 21a that pivotally supports the right side of the rotation roller 1 shown in the figure, and the tip of the pointer faces the rotation roller 1 side. In the present embodiment, the needle 15 protruding from the end of the support member 21a is punched out and bent at a right angle.
As shown in FIG. 4, the opening side (the left side in the figure) of the main body of the rotating roller 1 is held by a support member 21 b that pivotally supports the left side face in the figure of the disk 11, and the disk 11 is fixed. An elastic contact member 14 that is elastically contacted by a spring force with teeth 12 (concave portion or convex portion) provided on the outer periphery of 11 at regular intervals is attached. One end of the elastic contact member 14 is fixed to the support member 21a so that the elastic contact member 14 can come into contact with the rotating teeth 12 one after another. That is, the disk 11 is elastically attached to the elastic contact member 14 and is rotatably attached.

Here, in this embodiment, since the elastic contact member 14 made of a metal plate is elastically contacted with the teeth 12 of the plastic disc 11, the teeth 12 of the circular plate 11 rotate and elastic elastic members. A sound is generated each time the 14 contacts the tooth 12.
In the present embodiment, the impact when the teeth 12 come into contact with the elastic contact member 14 is vibrated and transmitted to the rotating roller 1 integrated with the disk. The vibration is applied to the pulling side of the adhesive tape 42 via the adhesive tape 42 as a touch.
In order to carry out the present invention, the shapes and materials of the teeth 12 and the elastic contact member 14 are not limited to the present embodiment, and a sound is generated each time the elastic contact member 14 comes into contact with the teeth 12. However, in order not only to generate sound when the teeth 12 come into contact with the elastic contact member 14, but also to provide a response to the pulling side of the adhesive tape 42, the teeth 12 are elastic members. It is desirable to use a material that does not absorb the shock when it contacts 14 and can transmit vibration to the adhesive tape 42.

The elastic contact member 14 does not stop the rotation of the teeth 12. That is, when the rotation of the disk 11 stops, it becomes difficult to measure the rotation of the rotating roller 1 according to the length of the drawn adhesive tape 42 in the structure in which the rotating roller 1 does not rotate. Each time the contact member 14 comes into contact with the teeth 12, a sound is generated, and the pulling side of the adhesive tape 42 is responsive.

In this embodiment, one end of the elastic contact member 14 is fixed to the base side of the support member 21b. However, the elastic contact member 14 is not limited to the position, and the elastic contact member 14 is a rotating disk 11. If it can be elastically contacted with the teeth 12, it can be installed at an arbitrary position. For example, the elastic contact member 14 can be provided so as to span a pair of the support member 21a and the support member 21b. Furthermore, it is possible to extend the pointer 15 so as to elastically contact the teeth 12 and to integrate the elastic contact member 14 and the pointer 15.

In FIG. 1, one end of a pair of support members 21 is connected to the upper ends of a pair of leg members 22 via a coil spring 31 a and a coil spring 31 b as elastic force applying members 31, respectively. It is free to turn as an axis. The coil spring 31a and the coil spring 31b give the rotating roller 1 an elastic force that biases the central axis of the rotating roller 1 with respect to the central axis direction of the adhesive tape 42 via the support member 21.
In the present embodiment, the elastic force applying member 31 is made of the elastically deformable coil springs 31a and 31b. However, the present invention is not limited to this, and the adhesive tape 42 is not limited to this. It is sufficient that an elastic force is applied to the rotating roller 1 with respect to the central axis direction so that contact between the adhesive tape 42 and the rotating roller 1 is prevented from causing a slip. For example, an elastically deformable rubber material may be used as the elastic force applying member 31 or a steel plate. Further, the elastic force applying member 31 may be one of a coil spring 31a and a coil spring 31b that can be elastically deformed.
In the present embodiment, the coil springs 31a and 31b as the elastic force imparting members 31 are mounted between the one end of the pair of support members 21 and the upper end of the pair of leg members 22, respectively. Is not limited to this position, and any number of positions may be used as long as an elastic force can be applied to the rotating roller 1. For example, an elastic force applying member 31 can be provided between the side surfaces of the rotating roller 1 and the disc 21 and the pair of support members 21.

And as shown in FIG.1 (b), a pair of leg member 22 to which the rotating roller 1 was attached is joined by the junction part 23 which consists of synthetic resins of a lower end. Furthermore, a space is provided in the holder 24 so that the joint 23 can be inserted, and the joint 23 is attached to the holder 24. A double-sided tape 25 for adhering to the tape cutter body 41 is attached to the surface of the holder 24.
As a result, if the holder 24 is previously attached to the tape cutter body 41 via the double-sided tape 25, when the adhesive tape 42 is quantitatively cut, it is possible to join the rotary roller 1 via the pair of support members 21. By attaching the portion 23 to the holder 24, the rotating roller 1 can be attached to the tape cutter body 41, and the adhesive tape 42 can be quantitatively cut.

Here, in the present embodiment, the elastomer 3 or the like is rotated around the outer peripheral surface 42a of the adhesive tape 42 formed by attaching an adhesive to one side and wound around the outer surface 42a of the adhesive tape 42. An anti-slip material is provided, and the rotary roller 1 is provided with a scale 13 around it.
The mounting portion for attaching the rotary roller 1 to the tape cutter body 41 via the support shaft portion 26 that rotatably supports the rotary roller 1 of the present embodiment and the support member 21 that holds the support shaft portion 26 is supported. It is comprised from the member 21 and the leg part 22. As shown in FIG.
The elastic force applying member 31 that applies an elastic force that biases the central axis of the rotating roller 1 with respect to the central axis direction of the adhesive tape 42 of the present embodiment is provided on the adhesive tape 42 via the support member 21. The central axis side of the rotating roller 1 is biased with respect to the central axis direction.
Further, in the present embodiment, on the support portion 21 side that indicates the scale 13 of the rotating roller 1 that measures the length of the drawn adhesive tape 42 according to the rotation distance of the rotating roller 1 that rotates according to the drawing distance of the adhesive tape 42. The measuring part having the provided pointer 15 is configured.

As shown in FIG. 5, when the adhesive tape 42 is not quantitatively cut, the holder 24 remains attached to the tape cutter body 41 and passes through the top dead center against the elastic force of the coil spring 31a and the coil spring 31b. If the pair of support members 21a and 21b are brought into contact with the stoppers 22a at the upper ends of the pair of leg members 22, the retreat is stopped, and the coil spring is stopped at that position. It can be stopped by receiving the elastic force of 31a and coil spring 31b. That is, the use of the measurement function can be stopped while the holder 24 is attached to the tape cutter body 41.
Of course, when the quantitative cutting of the adhesive tape 42 is not performed, it is possible to remove the joining portion 23 from the holder 24 while the holder 24 remains attached to the tape cutter body 41.
Therefore, in the present embodiment, when performing quantitative cutting of a desired constant dimension, the rotating roller 1 can be easily attached to the tape cutter body 41, and when the quantitative cutting is unnecessary, the function is provided. It is also possible to remove the rotating roller 1 from the tape cutter main body 41, and it is possible to easily switch between the quantitative cutting and the normal cutting, and to make the rotating roller 1 last longer.

Further, in the present embodiment, the double-sided tape 25 is attached to the holder 24 so that the holder 24 is attached to the tape cutter body 41 via the double-sided tape 25. However, the present invention is not limited to this. For example, the holder 24 can be attached to the tape cutter body 41 by attracting the holder 24 and the tape cutter body 41 with a magnet.
In addition, since the holder 24 can be easily attached to another tape cutter main body 41 by peeling the double-sided tape 25 of the holder 24 and attaching a new double-sided tape 25 to the holder 24, a plurality of tape cutter main bodies 41.

In the present embodiment, the holder 24 is provided, and the joining portion 23 in which the rotating roller 1 is disposed via the holder 24 can be attached to the tape cutter main body 41. The holder 24 can be attached to the tape cutter main body 41 by attaching the double-sided tape 25 directly to the tape cutter main body 41 or by attracting the holder 24 and the tape cutter main body 41 with a magnet. it can. Also by these, the rotating roller 1 can be easily attached to the tape cutter main body 41 when performing quantitative cutting of a desired fixed dimension, and the rotating roller 1 can be easily detached from the tape cutter main body 41 when not performing quantitative cutting. it can. That is, it is possible to easily switch between the quantitative cutting and the normal cutting, and it is possible to obtain the effect that the rotating roller 1 can be extended.

Next, an operation of quantitatively cutting the tape using the tape quantitative cutting apparatus according to the present embodiment will be described with reference to FIG.

In FIG. 5, a tape cutter main body 41 is a relatively large and manual one that is generally used in a state where it is placed on a desk that is widely used in homes and offices. When the tape is cut, an adhesive tape 42 such as a cellophane tape is used. The reel 49 is held on the outer periphery with the central axis of the adhesive tape 42 as the center of rotation. The adhesive tape 42 corresponds to a cellophane tape, a resin tape, a paper tape, a cloth tape, etc. having an adhesive layer formed on one side.

When performing quantitative cutting of the adhesive tape 42 having a desired fixed length, first, as shown in FIG. 1A, the joint portion 23 in a state where the rotating roller 1 according to the embodiment of the present invention is disposed. Is inserted into the holder 24. Then, the holder 24 in a state where the rotating roller 1 is connected is attached to the main body wall 43 on the back side of the tape cutter main body 41 via the double-sided tape 25. At this time, the rotating roller 1 contacts the outer peripheral surface 42 a of the adhesive tape 42, and the attachment position of the holder 23 to the main body wall 43 on the back side of the tape cutter main body 41 is rotated in conjunction with the rotation of the adhesive tape 42. Set with double-sided tape 25.
Next, in the present embodiment, the rotary roller 1 is set to rotate so that the numeral 0 attached on the scale 13 is positioned at the tip of the pointer 15 when viewed from the front. At this time, the elastic contact member 14 is in elastic contact with the teeth 12.

Thereafter, as in the case of cutting the adhesive tape 42 using a normal tape cutter, the tip of the adhesive tape 42 is picked and the adhesive tape 42 is pulled out. Then, like the normal tape cutter, the adhesive tape 42 also rotates by the amount that the adhesive tape 42 is pulled out. However, in this embodiment, the rotating roller 1 is in contact with the outer peripheral surface 2 of the adhesive tape 42. The adhesive tape 42 contacts the adhesive tape 42 and the outer peripheral surface 2 of the rotating roller 1 moves in the same manner, and the rotating roller 1 also rotates in the X direction in conjunction with the rotation of the tape 42 due to friction.
Here, since the rotating roller 1 has the outer peripheral surface 2 made of the elastomer 3, the contact resistance between the rotating roller 1 and the adhesive tape 42 is high.

Furthermore, even if the outer diameter of the adhesive tape 42 changes due to consumption (drawn and used) of the adhesive tape 42, it comes into contact with the adhesive tape 42 due to its own weight of the rotating roller 1 and the elastic force of the coil spring 31 a and the coil spring 31 b. However, since the rotating roller 1 is provided with an elastic force in the axial direction of the reel 49 by the coil spring 31a and the coil spring 31b, the rotating roller 1 is always applied to the outer peripheral surface 2 of the adhesive tape 42. Can be brought into close contact with each other.
Therefore, since the adhesive tape 42 is always pressed against the rotating roller 1, the outer peripheral surface of the adhesive tape 42 and the rotating roller 1 moves exactly the same due to frictional conduction by a constant contact pressure, and the adhesive tape 42 is bonded. The rotating roller 1 rotates by the distance that the tape 42 has rotated.

As the rotary roller 1 rotates, the scale 13 of the rotary roller 1 also rotates. Therefore, by reading the scale 13 at the tip of the pointer 15, the distance that the rotary roller 1 has rotated can be measured.
Further, as the rotating roller 1 rotates, the teeth 12 of the disk 11 integrally provided on the side surface of the rotating roller 1 also rotate together, so that one end is rotatably fixed to the support member 21b. The contact member 14 elastically contacts the rotating teeth 12 one after another. A sound is generated every time the tooth 12 and the elastic contact member 14 come into elastic contact, and a response is given through the adhesive tape 42 pulled out to the pull side of the adhesive tape 42.
Accordingly, by measuring the sound of the elastic contact member 14 elastically contacting the teeth 12 and the number of responses felt by the puller side via the adhesive tape 42, the rotation of the rotary roller 1 integrated with the disk 11 can be used for adhesion. The distance the tape 42 is pulled out can be measured.

Therefore, in the present embodiment, by reading the scale 13 at the position of the pointer 15, further, the number of responses that the elastic contact member 14 has elastically contacted with the teeth 12 and the feeling that the puller side felt through the tape. Can be measured to measure the distance the rotating roller 1 has rotated. Further, as described above, the length of the drawn adhesive tape 42 can be accurately measured by measuring the rotation distance of the rotating roller 1. Therefore, the length of the adhesive tape 42 drawn out in this way is measured, and the adhesive tape 42 is guided to the cutting blade 44 formed on the tape cutter body 41 when the adhesive tape 42 having a desired fixed dimension is drawn out. By pressing, it becomes possible to cut the adhesive tape 42 of a desired fixed dimension.
In this way, by accurately measuring the length of the drawn-out adhesive tape 42, a quantitative cutting apparatus for the adhesive tape with less error between the desired length and the length of the cut adhesive tape 42 is obtained.

Thus, the adhesive tape quantitative cutting device of the present embodiment is brought into contact with the outer peripheral surface 42a of the adhesive tape 42 formed by adhering the adhesive on one side and winding the adhesive tape 42 in accordance with the drawing distance of the adhesive tape 42. An anti-slip material such as an elastomer 3 is arranged around the rotation, and a rotary roller 1 is provided with a scale 13 around it, and a support shaft portion 26 and a support shaft that rotatably support the rotary roller 1. A support member 21 that attaches the rotating roller 1 to the tape cutter body 41 via the support member 21 that holds the portion 26, and a mounting portion that includes the leg portion 22, and the central axis of the rotating roller 1 with respect to the central axis direction of the adhesive tape 42. Rotation roller that measures the length of the drawn-out adhesive tape 42 according to the rotation distance of the elastic force applying member 31 that applies the elastic force that is biased and the rotation roller 1 that rotates according to the pull-out distance of the adhesive tape 42. Those comprising a measurement portion having a pointer 15 provided on the supporting portion 21 side for indicating the scale 13 in La 1.

Here, in the present embodiment, the length of the pulled-out adhesive tape 42 is determined by measuring the sound of the elastic contact member 14 elastically contacting the teeth 12 and the number of responses felt by the puller side via the adhesive tape 42. Therefore, when the adhesive tape 42 having a desired fixed dimension is pulled out, the adhesive tape 42 is guided to the cutting blade 43 formed on the tape cutter main body 41 and pressed, whereby the desired fixed constant is obtained. Since the adhesive tape 42 having a size can be cut, in the present embodiment, it is possible to cut the adhesive tape 42 having a desired fixed size without the puller side of the adhesive tape 42 looking at the scale 13.

That is, in the present embodiment, even if the pulling side of the adhesive tape 42 is away from the adhesive tape 42, it is possible to quantitatively cut the adhesive tape 42 having a desired fixed dimension. The operation of pulling out and cutting the tape 42 can be performed, and another operation can be performed simultaneously with another hand. Particularly when performing quantitative cutting of a tape having a desired fixed dimension repeatedly in large quantities, There is also an effect that the work can be performed quickly and efficiently.
In the present embodiment, when the elastic contact member 14 comes into elastic contact with the teeth 12 over the rotational distance of the rotary roller 1, a sound is generated, and the puller side gives a response through the adhesive tape 42. The above-described effect can be obtained even with either one that generates a sound or gives a response through the adhesive tape 42 drawn to the puller side.

Further, in the present embodiment, the pulling side of the adhesive tape 42 looks at the scale 13 and the number on the scale at the position of the pointer 15, and furthermore, the sound of the elastic contact member 14 elastically contacting the teeth 12. The length of the pulled-out adhesive tape 42 is measured by measuring the distance that the rotating roller 1 has rotated by measuring the number of responses that the puller side felt through the adhesive tape 42. When the present invention is carried out, any one of the measurement methods may exist.

The rotation of the rotating roller 1 rotating according to the pulling distance of the adhesive tape 42 is fixed to the support portion side including the pointer 15 indicating the scale 13 of the rotating roller 1 for measuring the length of the drawn adhesive tape 42. The measuring unit having the pointer 15 rotates in a state of elastic contact with the disk 11 having a gear 12 having a fixed relationship with the scale 13 of the rotating roller 1 and the gear 12 around the disk 11. A measurement auxiliary part having an elastic contact member 14 that allows movement is formed, and the measurement auxiliary part generates a sound according to the pull-out distance of the adhesive tape 42.
And when implementing this invention, it is not limited to the said measurement part, As long as the length of the pulled-out adhesive tape 42 can be measured, any may be sufficient. It is also possible to measure the length of the tape drawn by inputting the rotation distance of the rotating roller 1 as a counter.

As shown in FIG. 5, in the present embodiment, when the cutting blade 43 of the tape cutter main body 41 is the front, the adhesive tape quantitative cutting device applies the double-sided tape 25 to the main body wall 43 on the back side of the tape cutter main body 41. In the case of carrying out the present invention, a rotating roller that makes the distance of the wound adhesive tape 42 that rotates as the adhesive tape 42 is drawn contact the outer peripheral surface 42 a of the adhesive tape 42. 1, the length of the pulled-out adhesive tape 42 is measured, and the rotating roller 1 is brought into contact with the outer peripheral surface 42 a of the adhesive tape 42 to interlock with the rotation of the adhesive tape 42. If the rotary roller 1 can be rotated, the position for attaching the adhesive tape quantitative cutting device according to the present embodiment in the tape cutter body 41 is not particularly limited. . Of course, the position of the rotating roller 1 to be brought into contact with the adhesive tape 42 is not limited to the position shown in FIG.
For example, in the present embodiment, the joint portion 23 for joining the pair of leg members 22 is provided, but the holders 24 that can be respectively inserted into the pair of leg members 22 without joining the pair of leg members 22 are provided. By providing and attaching the holders 24 to the main body walls 43 on both sides of the tape cutter main body 41, the adhesive tape quantitative cutting device in the present embodiment can also be attached.

As described above, according to the present embodiment, the position for attaching the quantitative cutting device for the adhesive tape according to the present embodiment is not particularly limited, and therefore can be attached to the tape cutter body 41 of various forms.
Therefore, when performing quantitative cutting of the adhesive tape 42 having a desired fixed size, if there is one adhesive tape quantitative cutting device according to the present embodiment, it can cope with existing tape cutters of various forms, and bothersomely new tapes. There is no need to purchase a cutter. In particular, a relatively large and manual cellophane tape cutter that is normally used in a state of being placed on a table generally used in homes and offices is provided with a main body wall 43 on which an adhesive tape 42 is rotatably mounted. Therefore, the shape and type of the tape cutter to which the adhesive tape quantitative cutting device according to the present embodiment can be attached are not limited, and the degree of freedom of the attachable tape cutter is high.

Moreover, when implementing this invention, the attaching part which attaches the rotating roller 1 to the tape cutter main body 41 is not limited to this Embodiment. For example, it is possible to attach to the tape cutter body 41 via a clip. According to the clip, a part of the tape cutter main body 41 can be clamped by the biasing force of the spring, so that a storage chamber is provided between the wound adhesive tape 42 and the tape cutter main body 41 so that a pair of spring clamping pieces can be inserted. The tape cutter main body 41 having the tape cutter main body 41 can be attached to the main body wall 43 on the back surface side or the side surface side of the tape cutter main body 41. Of course, the tape cutter may be clamped via a vice or the like. Even in such a case, the rotating roller 1 can be easily attached to the tape cutter body 41 with a clip, and the adhesive tape 42 can be quantitatively cut. On the other hand, when the adhesive tape 42 is not quantitatively cut, the function can be removed, and the rotating roller 1 can be easily detached from the tape cutter body 41 by removing the clip. Therefore, the rotating roller 1 can be easily attached to the tape cutter body 41 when performing a fixed cutting with a desired fixed dimension, and the rotating roller 1 can be easily detached from the tape cutter body 41 when not performing a fixed cutting. Switching between the quantitative cutting and the normal cutting can be easily performed, and the rotating roller 1 can be made long-lasting.

In the present embodiment, the rotational distance of the wound adhesive tape 42 that rotates as the adhesive tape 42 is drawn is measured by the rotational distance of the rotating roller 1 that contacts the outer peripheral surface 42 a of the adhesive tape 42. In the tape cutter in which the adhesive tape 42 such as a wound cellophane tape is rotatably held, the outer peripheral surface of the adhesive tape 42 is usually measured. Since it is not covered with the main body wall 43 or the like, the outer peripheral surface 42a of the rotating adhesive tape 42 is exposed, and the size of the rotating roller 1 brought into contact with the outer peripheral surface 42a of the adhesive tape 42 is not limited. The size of the roller 1 can be set freely.

Further, the rotating roller 1 and the disc 11 are rotatably mounted about the support shaft 26, and are supported by a pair of support members 21 on the side surfaces of the rotating roller 1 and the disc 11, and one end of the support shaft 26 is provided. Is fixed with a nut 27. Therefore, by removing the nut 27, the rotating roller 1 and the disk 11 can be easily removed from the support member 21, and the rotating roller 1 and the disk 11 having different sizes (diameters) and intervals between the teeth 12 can be obtained. Can be exchanged. Here, since it is often necessary to quantitatively cut a tape of 5 cm, 10 cm, 15 cm, or 20 cm, it is possible to replace the rotating roller 1 with a circumference of any one of 5 cm, 10 cm, 15 cm, and 20 cm. It is preferable to keep it. Moreover, 9 cm and 12 cm are used for sealing of standard mail and non-standard mail.

In this way, by aligning the rotating rollers 1 having different sizes (diameters) and intervals between the teeth 12 and the corresponding discs 11, it is possible to quantitatively cut an adhesive tape having a desired fixed dimension that meets the purpose. It is possible to select the optimum rotating roller 1 and disc 11 combined, and quantitative cutting according to a desired constant dimension can be performed. For example, the scale 13 and the teeth 12 can be provided at fine intervals (for example, in units of 1 mm) by using the rotating roller 1 having a large circumference having a diameter of 20 cmm and the corresponding disk 11, so that the diameter is 5 mm. It can cope with a case where a fine length error range of a unit or less is desired. Further, as the length for which the tape according to the present invention is supposed to be quantitatively cut, a structure that changes the sound at a specific length on the premise of a length necessary for sealing an envelope of a size that can accommodate A4 size paper. Or it can also be set as the structure where a load changes.

In this case, even if a person who pulls out the adhesive tape 42 keeps an eye on the adhesive tape 42, the adhesive tape 42 is applied to the cutting blade 44 formed on the tape cutter body 41 immediately after hearing the sound or feeling the response. Since the adhesive tape 42 having a length corresponding to the width of the envelope of No. 4 can be quantitatively cut by guiding and pressing the adhesive tape 42, the adhesive tape 42 is drawn and cut with one hand as described above. It is also possible to carry out a work and perform another work with another hand at the same time. Particularly, when performing quantitative cutting of the adhesive tape 42 of a desired fixed dimension repeatedly in large quantities, both the above work can be performed quickly and easily. The effect that it can carry out efficiently is also acquired.

In the present embodiment, the rotation roller 1 can be replaced only by fixing and removing with the nut 27. However, the present invention is not limited to this embodiment. For example, the joining portion 23 in a state where the rotating roller 1 is connected is extracted from the holder 24, and the joining portion 23 in a state where the rollers are connected in different sizes (diameters) is inserted into the holder 24, so that the size ( It is also possible to replace the rotating roller 1 with a different diameter.
