Abstract

PURPOSE:To always automatically draw out a tape of predetermined length by providing a means which stops rotation of a tape roll when a drawn out length of the tape obtains the predetermined length by detecting the drawn out length of the tape when it is drawn out. CONSTITUTION:Drawn out length of a tape is detected by detecting a rotational amount of a roller 20 in a control part by an optical sensor 34. When a tape drawn out amount from this tape roller obtains a predetermined value, a solenoid 56 is excited, and rotation of the roller 20 is stopped by bringing a brake member 58 into contact with a peripheral surface of the roller 20. A brake is applied to rotation of a tape roll 10, with which this roller 20 is brought into press contact, to stop rotation of this tape roll 10. In this way, the length of the drawn out tape is always set to the predetermined value, and the tape 12, drawn out by this desired length, is cut by a cutter blade 6.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention is a tape holder, more specifically, a tape holder that rotatably supports a roll of adhesive tape or the like wound in a roll, and pulls out and cuts the tape at a fixed length. This relates to a tape holder.

(Prior art) Conventionally, as an adhesive tape holder, an adhesive tape roll wound into a roll is supported on a core having a spindle at the center.
It is known that the core is rotatably supported on a support base, and the adhesive tape pulled out from the adhesive tape roll is cut by a cutter blade provided on a part of the support base. This type of holder is relatively heavy and is used by pulling out the tape and cutting it while it is placed on a desk or the like.

(Problem to be Solved by the Invention) When using such an adhesive tape holder, the tape is pulled out from the tape roll to a desired length and cut, but this length is often a fixed length. . For example, to close the opening of a regular envelope, etc., lO~12C! It only needs to be about R, and in the case of a B5 or A4 square cylinder, it is sufficient to pull out the length to close the mouth of the fixed size. However, in this type of adhesive tape holder, the length of the tape to be drawn out is free, so the actual situation is that the length of the tape to be drawn out is measured by eye. For this reason, even if the length to be pulled out is determined, it is necessary to measure the length each time as a guide, which is not only inaccurate but also troublesome.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a holder for adhesive tape, etc., which automatically stops the drawer when a predetermined length of tape is pulled out, so that a predetermined length of tape can be automatically pulled out at all times. be.

(Means for Solving the Problems) The tape holder according to the present invention is a means for detecting the length of the tape when the tape is pulled out, and stopping the rotation of the tape roll when the length of the tape reaches a predetermined value. It is characterized by having the following.

For example, in the case of adhesive tape, this drawer length may be set to a fixed length for standard-sized envelopes, or may be switchable to several typical lengths, but is preferably set to the user's preference. It is better to be able to set the length to , and to be able to fix it at the set length. Further, since there may be cases where you want to freely draw out the length you like, it is preferable to make the above setting releasable.

Note that stopping the rotation of the tape roll does not only mean directly increasing the rotation of the tape roll, but also stopping the core that supports the tape roll or the roller that is in contact with the outer periphery of the tape roll, thereby indirectly increasing the rotation of the tape roll. This shall also include stopping the system.

Furthermore, various known sensors and mechanisms can be used as the mechanism for detecting or setting the tape draw-out length.

(Operations and Effects) According to the tape holder of the present invention, the rotation of the tape roll is stopped when the length of the tape to be pulled out reaches a predetermined length, so that the length of the tape that can be pulled out is always the predetermined length. There is no need to measure by eye.

(Example) Embodiments of the present invention will be described in detail below with reference to the drawings.

1.2.3 and 4 show one embodiment of the present invention, in which FIG. 1 is a perspective view, FIG. 2 is a partially cutaway side view, FIG. 3 is a plan view, and FIG. FIG. 3 is a block diagram showing the structure and circuit system of a control section.

The adhesive tape holder rotatably supports a core 4 on a support base 2, and the core 4 includes a cylindrical main body 42 that supports an adhesive tape roll 10 wound into a roll, and a main body 4.
The support shaft 44 is fixed at the center of the shaft 2 and protrudes from both sides in the axial direction. Furthermore, a cutter blade 6 is provided at one end of the support base 2 for cutting the adhesive tape 12 pulled out from the adhesive tape roll 1o. As is well known, the support base 2 is provided with a groove 14 for guiding the support shaft 44. These configurations are no different from known adhesive tape holders, so detailed explanations will be omitted.

In addition to the above-mentioned basic configuration, the adhesive tape holder according to the present invention detects the length of the adhesive tape I2 when it is pulled out, and when the length of the adhesive tape I2 reaches a predetermined value, the rotation of the adhesive tape roll IO is controlled. Means for stopping is provided. In the embodiment shown in FIGS. 1 to 4, a rotatable roller 20 is pressed against the outer circumferential surface of the adhesive tape roll IO, and the roller 20 rotates as the tape roll IO rotates. It is designed to measure the length of the drawer. This roller 20 is stopped when a predetermined length of tape is further drawn out, and has the function of stopping the rotation of the tape roll 10 that comes into contact with it.

The roller 20 is rotatably supported by an arm 2B biased by a spring 24 and supported by a shaft 22 at the bottom of the support base 2 so as to be elastically pressed against the outer peripheral surface of the tape roll IO. As a result, even if the diameter of the tape roll 10 decreases, the roller 20 is always in contact with the outer periphery of the tape roll 10.
The length of the tape 12 that rotates with the rotation of the tape roll 2o and is drawn out can be accurately measured.

An operation button 30 is provided on the upper surface of the support base 2 to control the stopping action of the tape roll 20 by the roller 20. These operation buttons 30 include a start button 32 for starting the measuring scale when setting the desired drawer length, a memory button 34 for storing the length of the tape 12 when the desired length is drawn out, and - There is a clear button 38 that releases the memory when you want to change the length that was previously stored, and a release button 38 that allows you to leave the memory as it is and release the set length at any time so that you can temporarily pull out a tape of the desired length. It consists of Also, operation button 3
A display window 35 is provided near o to display the length of the tape that has been pulled out.

When using, first press the start button 32, then pull out the tape 12 to the desired length while looking at the display window 35, and when the desired length is reached, press the memory button 34.
Press. Therefore, the tape 12 is cut with the cutter blade 6 and used for the first time. As a result, from now on, when the tape 12 is pulled out to the set length, the roller 20 stops rotating the tape roll IO, so if the tape 12 is cut at that point, a tape of the same length will always be obtained.

If you want to change the set length, press the clear button 36 to clear the memory and make a new setting. Leave the settings as they are, and if you occasionally want a tape with a length other than the settings, you can release the settings by pressing (while pressing) the release button 38, and then pull out the tape.

Various types and arrangements of the 30 operation buttons are possible, but as shown in FIG.
The configuration of the control unit including 0 will be explained.

A large number of marks 52 are provided on the side surface of the roller 20 to indicate the amount of rotation. This is a device in which a large number of optical marks that can be detected by optical reflection or transmission are provided radially at equal intervals, and an optical sensor 5 is provided facing the side surface of the optical mark.
4 to detect the amount of rotation of the roller 20. Since this principle and configuration are well known, detailed explanation thereof will be omitted.

Further, a brake member 58 is installed below the roller 20 and is moved up and down by a solenoid 56.
8 to stop the rotation of the roller 2o. roller 2
When the rotation of the sono tape roll 1o is stopped, this applies a brake to the rotation of the tape roll 1o that is in pressure contact with the sono tape roll 1o, and the rotation of the sono tape roll 1o is stopped.

Solenoid 56. Sensor 54. The operation button 3o is connected to a control circuit 60, and the control as described above is performed by the action of the control circuit 6o. That is, the start button 32
．． Memory button 34. The clear button 36 is the sensor 54
The start button 3 is also connected to the memory circuit 62.
The amount of rotation of the roller 2o from when 2 is pressed until the memory button 34 is pressed is stored in the memory, and the set tape length is set. Next, when the roller 2o rotates, a stop signal is sent to the solenoid drive circuit 63 when the amount of rotation reaches a magnitude corresponding to the set tape length, and the drive circuit 63 drives the solenoid 56 to stop the brake member 58. Push it upward to stop the rotation of the roller 20.

This control is repeated until the start button 32 is pressed again, but when the start button 32 is pressed, the previous memory is erased and new settings can be made.

If the user wishes to erase the memory without pressing the start button 32, the memory can be erased by pressing the clear button 36.

The sensor 5 of the roller 20 is configured so that the display window 35 displays the length of tape drawn out after the start button 32 is pressed.
The output from 4 is input through memory circuit 62. The display window 35 has a digital display using, for example, an LED or a liquid crystal, and the tape is pulled out to a desired length while looking at a display such as 10100 (for example).

Note that the display method of the display window 35 does not have to be a digital display, and may be, for example, a scale method in which the scale moves.

According to the above embodiment, when the length of the tape to be cut to a certain length is known, the user presses the start button 32 and then pulls out the tape 12 while looking at the display on the display window 35.
When the desired length is displayed, press the memory button 34 to set the predetermined length. After that, if the tape 12 is pulled out, the tape 12 will no longer be pulled out at the set length as described above, so the tape 12 can always be cut to the predetermined length.

In addition, if you do not know the length of the tape, press the memory button 3 when the length you pull out by hand reaches the desired length.
Just press .

Note that the start button 32 is used instead of the clear button 36.
Since similar settings can be changed by pressing , the clear button 36 does not necessarily need to be provided.

The release button 38 is connected to the solenoid drive circuit 63,
This function prevents the solenoid 56 from operating. If you press the release button 38 even after a predetermined length has been set in the memory, the solenoid 56 will temporarily stop operating without erasing the memory. 20 rotations can be made free. For this purpose, the release button 38 may be pressed while being pressed, or may be pressed once to release the release button, and pressed once again to complete the release.

In the above embodiment, the desired length is set by looking at the display window while pulling out the tape, or it is also possible to set the desired length in advance without pulling out the tape. Such an example is shown in FIG.

In the embodiment shown in FIG. 5, a dial-type scale 37 is provided, and by visually checking the scale and turning the dial by hand to set the desired length scale, the length of the tape cut is set to that length. It has been made possible. That is, for example, if the scale 37 of the dial is set at 7C1n, the rotation of the tape roll 10 will stop when the tape 12 is pulled out by 7CIi. In addition, in this embodiment as well, it is desirable to enable the button-type setting of the above embodiment so that you can freely set the predetermined length to the desired length, so press the start button 3.
Two operation buttons, 2' and a memory button 34', and a release button 38' are provided. In addition, this release button 3B
' does not need to be provided for the same reason as mentioned above.

In both of the above two embodiments, the set length can be set to an arbitrary length, but in this case, several known predetermined lengths are set and the lengths are selected. Good too. For example, it is conceivable to predetermine three types of lengths and provide three buttons for selecting them. Such an example is shown in FIG.

The embodiment shown in FIG. 6 is provided with three cut length selection buttons 72, 74, and 76, A, B, and C, and a release button 78 that allows the tape to be freely drawn out.

This allows the A button 72 to be set to about 10 to 12 on, which is just right for closing the opening of a standard envelope, and the B button.
As with the B button 74, which is set to a length that is just right for closing the opening of the envelope that contains the number 5, you can determine the set length for each button in advance, and easily change the set length by pressing these buttons. It can be selected and set.

For example, the setting length of these selection buttons may be determined by the manufacturer in advance and fixed at the time of manufacture, and displayed above or next to the button as ``Standard shape'' or ``B5'', etc., but the user can set the length himself/herself. You can do it like this. For example, by pressing the A button 72 for a long time (for example, 2 seconds or more), pulling out the tape, pulling it out by the desired setting length, and pressing the A button 72 again, the tape can be adjusted to the length that was pulled out at that time.
The length of the button 72 may be set. Thereby, the next time the user presses the A button 72 and pulls out the tape, it is possible to prevent the tape from being pulled out at that length.

In addition, such selection buttons 72, 74, 76, the start button 32, the memory button 34, or the display window 3
If a 5th grade unit is also installed, the usability will be further improved and it will be convenient for practical use.

In the embodiment shown in FIG. 5, instead of the dial scale 37, a numeric keypad 37' is provided as shown in FIG.
It is also possible to set a desired setting length using this numeric keypad 37'. That is, for example, with the numeric keypad 37',
60'' and then pull out the tape, the tape roll 10 can be made to stop at a length of 60 m.

Once set, the same length remains set unless the numeric keypad 37' (or start button 32') is pressed again.

Alternatively, instead of pressing the start button 32' and then pulling out the tape, the settings can be made by pressing the numeric keypad 37' and then pressing the memory button 34'.

In each of the above embodiments, the rotation of the tape roll 10 is stopped when the tape 12 is pulled out to the set length, and after the tape is cut, the tape 12 is further pulled out.
When attempting to pull out the tape, the tape roll 10 must be allowed to rotate, and for this purpose, the solenoid 5B that has been activated must be released before the next tape is pulled out. A conceivable method for this is to continue driving the solenoid 56 for a period of time after the tape 12 is stopped being pulled out until the tape is cut, and then to release the driving. This means, for example, that the solenoid 5B is
It is sufficient to drive with a pulse having a width of about seconds. If this length is too short, cut the tape roll 10cm before cutting the tape.
will start rotating again, and if it is too long, it will be inefficient during continuous work.

Although each of the above embodiments relates to an adhesive tape holder, the present invention can be applied to anything other than adhesive tape as long as it is supported in a roll like a paper tape and can be pulled out and cut with an attached cutter. Needless to say, it is also applicable.

Furthermore, in the above embodiment, stopping the rotation of the tape roll is as follows:
Although this is done by a roller in contact with the outer peripheral surface of the tape roll, any other type of braking mechanism may be used as long as it stops the rotation of the tape roll. Furthermore, it goes without saying that the formats of the operation buttons and display windows are not limited to those of the embodiments described above, and can be modified in various ways.
