Abstract
Description
Automatic paper cutting device and cutting method thereof
[0001] The present invention relates to an automatic tissue cutting device and a cutting method thereof, and more particularly, to a device that automatically unwinds a roll of tissue when the user wishes to use the tissue, and winds the unwound tissue to a predetermined length that can be used by the user. The present invention relates to an automatic tissue cutting device and a cutting method thereof, which comprises a cutting process that winds the tissue to a predetermined length during the tissue winding process, and naturally cuts the rolled tissue.
[0002] The information contained in this background section is intended to enhance understanding of the background of the invention and may include matters that are not prior art already known to a person of ordinary skill in the art to which this technology pertains.
[0003]
[0004] In general, toilet paper is used in a wide range of daily life, such as removing facial makeup, disposing of the toilet, and wiping moisture or foreign substances from the hands, so it is always close by and used frequently.
[0005] To make it easier to use this type of toilet paper, the toilet paper is rolled into a roll shape and stored in a built-in toilet paper holder. In the past, users would pull out the necessary amount of toilet paper by hand.
[0006] However, the toilet paper stored in the conventional toilet paper holders described above typically required users to tear the paper using both hands. However, if one hand was not fully functional, tearing the paper could be extremely inconvenient. In other words, existing toilet paper holders were a manual method that required users to manually pull and tear the paper, which was not only inconvenient, but also difficult for people with disabilities or those with limited mobility to use.
[0007] Additionally, since the amount of toilet paper to be withdrawn is determined by the user's subjectivity, there was a problem of toilet paper waste due to users habitually pulling and tearing off the toilet paper excessively.
[0008] Additionally, the toilet paper rolled into a roll was cut too short by the cutting line, so the user could not extract the amount of toilet paper they needed, and the process of pulling and cutting the toilet paper had to be repeated several times, which was inconvenient.
[0009] In addition, when the toilet paper holder is stored inside an opaque container, it is difficult to easily recognize the presence of toilet paper, so there is an inconvenient problem in that the user has no choice but to open the inside of the toilet paper holder to check when to replace the toilet paper.
[0010] In particular, in places like bathrooms where a lot of water is used and a humid atmosphere is maintained, there was also the problem that toilet paper stored inside a toilet paper holder that was not waterproof easily got wet, causing inconvenience in use.
[0011] Meanwhile, an "automatic toilet paper supply device" is disclosed in Patent No. 10-1723490 by the applicant. The automatic toilet paper supply device will be briefly described below.
[0012] An automatic toilet paper supply device includes a case in which toilet paper rolled in a roll shape is mounted on a supply shaft and installed widthwise on the inside, a driving unit including a driving shaft that rotates and is connected to a stepping motor installed on the lower side of the case, a rolling unit that rotates and rolls toilet paper according to a detection signal of a photocoupler installed on the driving shaft and detects the end position of the toilet paper, and a control unit connected to the driving unit and the rolling unit.
[0013] When the photocoupler detects the waste paper that has been released from the supply shaft and moved downward, the drive shaft rotates a set number of times to wind, fold, and cut the waste paper, and the rolling unit includes a winding unit installed on the drive shaft that catches the waste paper and rotates it according to the detection signal of the photocoupler.
[0014] The winding unit is composed of front and rear grippers spaced apart from each other, and the front and rear grippers are made of electromagnets and are connected to a control unit so as to repeatedly close and open each other to catch and fix or release the fixation of the tissue paper, and are connected to a drive shaft and a pair of connecting rods so as to have a shape that opens upward around the drive shaft, and the photocoupler is installed facing each other on a pair of connecting rods on the upper side of the drive shaft.
[0015] The purpose of the present invention is to solve the above-mentioned problem, and to provide an automatic tissue cutting device and a cutting method thereof, which enable tissue to be automatically cut by a cutting device without the user having to pull the tissue to cut the tissue.
[0016] Another object of the present invention is to provide an automatic tissue cutting device and a cutting method thereof that enable physically challenged users, such as patients, the elderly, and the disabled, to freely use cut tissue paper by taking it out without moving or moving their bodies.
[0017] According to one embodiment of the present invention, a tissue automatic cutting device comprises: a compression cutting member (130) configured with a driving motor and two rollers to compress tissue (10) and pull it out in a downward direction; and a tissue winding member (150) that rotates the driving motor to wind the tissue (10) pulled out by the compression cutting member (130) onto a winding unit within a rotating space, wherein when the tissue is wound onto the winding unit to a predetermined length, the two rollers of the compression cutting member (130) stop rotating while keeping the tissue compressed, and the winding unit of the tissue winding member continues to rotate, thereby providing a cutting line sequential breaking means that when the cutting line of the tissue is broken, the cutting line of the tissue starts to break from one end and then progresses to the entire cutting line; And it further includes an anti-static means for preventing static electricity, and the anti-static means is a conductive grid (125) or two rollers installed in the rotating space, and an earth wire for transmitting static electricity to the outside is connected to the conductive grid (125), and the two rollers are conductive.
[0018] Here, as a cutting line sequential breaking means, the two rollers of the compression cutting member (130) are composed of a horizontal roller (131) formed concentrically and an inclined roller formed with an inclined surface, and the horizontal roller and / or the inclined roller are made to have elasticity.
[0019] In addition, as a cutting line sequential breaking means, a slope winding unit is configured on the waste paper winding member (150).
[0020] In addition, the automatic tissue cutting device operates when the user presses a button or when a proximity sensor is installed and the proximity sensor recognizes the presence of the user's hand when the user's hand is positioned around the proximity sensor, thereby operating the automatic tissue cutting device.
[0021] In addition, after the tissue is broken, the rotation of the winding unit is stopped so that the user can take out the broken tissue, and the rotation of the winding unit is stopped when the virtual plane formed by the two straight bars and the connecting bar that constitute the winding unit is perpendicular to the ground.
[0022] Additionally, when the user takes out the broken tissue after the tissue has been broken, the sensor that recognizes the absence of the tissue sends a signal so that the plane formed by the two straight bars and the connecting bar that constitute the winding unit is arranged in a state parallel to the ground.
[0023] In addition, the automatic paper cutting device includes a front upper door (112) that is installed to be openable so that paper (10) can be inserted into a supply shaft (116), a front lower case (113) that is installed at the bottom of the front upper door (112), and a rear case (114) that is installed at the rear of the front upper door (112) and the front lower case (113).
[0024] In addition, the automatic paper cutting device includes a rotating space (120) in which a paper winding member (150) for winding paper on a rear case (114) can be rotatably installed; a dust suction hole (121) formed on one side of the rotating space (120) to suck up dust generated when paper is unwound; and a suction fan (122) installed inside the dust suction hole (121).
[0025]
[0026] A method for automatically cutting waste paper according to one embodiment of the present invention comprises the steps of: (S10) unwinding waste paper (10) wound around a waste paper supply shaft (117) through a compression cutting member (130); (S20) unwinding the waste paper (10) to a length that can be wound around a waste paper winding member (150) and lowering it; and (S30) detecting the waste paper lowered to the position of the compression cutting member (130) through a photocoupler (151) installed in a rotating space (120). A step (S40) of winding the tissue paper (10) released from the compression cutting member (130) onto the winding unit by the driving motor of the tissue paper winding member (150). In a state where the tissue paper is compressed by the compression cutting member (130), the rotation of the roller of the compression cutting member is stopped, and one end of the cutting line (11) of the tissue paper is first cut by the rotation of the tissue paper winding member (150), and then the remaining cutting lines are sequentially cut, which includes a sequential cutting step (S50).
[0027] As described above, according to the automatic tissue cutting device and cutting method according to the present invention, a user does not have to directly cut a roll of tissue paper, and the tissue paper can be easily cut by the rotation of the compression cutting portion of the compression cutting member and the winding unit, and the effect is obtained that the user can take out the tissue paper wound on the winding unit and use it without directly cutting the tissue paper.

[0039] The advantages and features of the present invention, as well as the methods for achieving them, will become clearer with reference to the embodiments described below, along with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms.

[0040]
[0041] Hereinafter, a paper automatic cutting device and a cutting method thereof according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.
[0042]
[0043] Figures 1 and 2 are explanatory drawings showing an automatic paper cutting device according to a preferred embodiment of the present invention.
[0044] According to a preferred embodiment of the present invention, an automatic tissue cutting device (110) has an opening / closing door that can be opened and closed so that a roll of tissue can be inserted into the supply shaft (116) inside the automatic tissue cutting device (110). The opening / closing door is opened and closed around a rotating hinge (115). In the present invention, this is referred to as a front upper door (112). A front lower case (113) is formed at the bottom of the front upper door (112).
[0045] A rear case (114) is formed on the rear of the front upper door (112) and the front lower case (113). A compression cutting member (130) is formed inside the front upper door (112) and the front lower case (113) for extracting tissue paper (10), and a tissue wrapping member (150) is formed below the compression cutting member (130). The tissue paper is lowered by the compression cutting member (130) and wrapped around the tissue wrapping member (150).
[0046] A paper towel automatic cutting device (110) according to a preferred embodiment of the present invention comprises a front upper door (112) that can be opened and closed so that paper towel (10) can be inserted into a supply shaft (116). The lower portion of the front upper door (112) comprises a front lower case (113), and a rear case (114) installed at the rear of the front upper door (112) and the front lower case (113).
[0047] A waste paper automatic cutting device (110) according to a preferred embodiment of the present invention includes a compression cutting member (130) that serves to pull out waste paper (10), and a waste paper winding member (150) that serves to wind the waste paper (10) lowered by the compression cutting member (130).
[0048] According to an embodiment of the present invention, a tissue cutting device (110) stores tissue (10) in a roll shape on a supply shaft (116). According to an embodiment of the present invention, a tissue cutting device (110) includes a compression cutting member (130) that performs the function of extracting the stored tissue (10), and a tissue winding member (150) that winds the extracted tissue.
[0049] The paper cutting device (110) comprises a front upper door (112) that can be opened and closed at the top to enable paper (10) to be fed in. The front case (111) comprises a front upper door (112) and a front lower case (113) formed at the bottom of the front lower door. A rear case (114) is formed at the rear of the front case (111).
[0050] A rotating hinge (115) is provided on the lower side of the front upper door (112) to enable the opening and closing of the front upper door (112). In order to release the tissue (10), a supply shaft (116) that is installed to be rotatable is provided on the front of the rear case (114).
[0051] The tissue cutting device (110) is largely composed of a front case (111) and a rear case (114). The front case (111) is composed of a front upper door (112) and a front lower case (113) that are installed to be openable so that roll-shaped tissue (10) can be fed.
[0052] The front upper door (112) is installed so as to be opened and closed around a rotating hinge (115), and various driving motors capable of supplying rotational power are installed in the rear case (114).
[0053] At the lower part of the rear case (114), a tissue paper winding member (150) for winding tissue paper (10) is configured to be driven by a driving motor. A rotating space (120) is configured at one side of the lower part of the rear case (114). The tissue paper winding member (150) rotates within the rotating space to wind tissue. At one side of the rotating space, a dust suction hole (121) and a suction fan (122) for sucking dust through the dust suction hole (121) are configured. Fine dust generated when tissue paper (10) is unwound through the dust suction hole (121) is absorbed.
[0054] In addition, a conductive grid (125) is installed in the rotating space (120) to prevent static electricity generated when the paper (10) is released, and a ground wire (not shown) that transmits static electricity to the outside is connected to the conductive grid (125). Static electricity generated by the operation of this device is induced to the conductive grid (125), and the induced static electricity is transmitted to the outside through the ground wire, thereby preventing problems caused by static electricity in advance.
[0055] In addition, since the two rollers (see Fig. 3) provided in the compression cutting member (130) also have conductivity, problems caused by static electricity generated when the paper (10) is released can be prevented in advance.
[0056] The conductor grid (125) and two rollers serve as antistatic measures.
[0057]
[0058] Figure 3 is a diagram illustrating a compression cutting member of an automatic paper cutting device according to a preferred embodiment of the present invention. In the present invention, the front upper door of the paper cutting device is configured to be openable and closable around a rotating hinge (115).
[0059] In the present invention, the compression cutting member (130) includes a drive roller (131) and an idle roller (132). The drive roller is fixedly installed on the main body of the automatic paper cutting device, and the idle roller is fixedly configured on the front upper door (112). As the front upper door (112) is opened and closed around the rotation hinge (115), the idle roller also moves. When the front upper door (112) is closed, the idle roller and the drive roller are pressed against each other, and when the drive roller rotates, the idle roller also automatically rotates. When the front upper door (112) is opened, the idle roller is separated from the drive roller.
[0060] In the present invention, the compression cutting member includes an idle roller and a driving roller. The tissue cutting device of the present invention stores a roll of tissue (10) on a supply shaft (116), and the function of pulling out the rolled tissue (10) in a downward direction is performed by the compression cutting member (130) including an idle roller and a driving roller.
[0061]
[0062] Figures 4 and 5 are front views of a paper-rolling member according to a preferred embodiment of the present invention.
[0063] The tissue paper winding member (150) includes a winding unit (153) and a driving motor. The winding unit (153) is configured to be connected by two straight bars (155) and one connecting bar (154). When the driving motor rotates, tissue paper supplied from the compression cutting member (130) is wound around the winding unit.
[0064] The waste paper winding member (150) is located inside the rotating space (120). The waste paper winding member (150) functions to wind the waste paper (10) that is being unwound downward, and also provides tensile force to cut a certain amount of the wound waste paper. The winding unit (153) is installed to be rotatable by a driving motor installed in the rear case (114).
[0065] The driving motor rotates the winding unit (153) installed in the rotating space (120), and a photocoupler (152) is installed in the rotating space (120) to detect the waste paper (10).
[0066] When the tissue is detected by the photocoupler (152), the winding unit is rotated by the driving motor, so that the tissue is wound on the winding unit. The driving motor rotates by the amount set by the user.
[0067] The tissue paper winding member (150) includes a driving motor that enables the winding unit (153) to rotate, and a winding unit (153) that is rotated by the driving motor. The winding unit cuts the tissue paper (10) compressed by the compression cutting member (130) while winding the tissue paper (10).
[0068] The waste paper winding member (150) winds the waste paper (10) that is released downward in the waste paper space (120) so that the waste paper (10) is cut. The winding unit (153) is installed so as to be rotatable by a driving motor installed in the rear case (114).
[0069] The driving motor rotates the winding unit (153) installed in the rotating space (120), and a photocoupler (152) that detects that the paper (10) has been unwound to a certain length is installed in the rotating space (120).
[0070] The photocoupler (152) detects the loosened tissue (10) to a certain length (for example, a length approximately 1.5 to 2 times the length of the connecting bar (154) of the winding unit (153)) and rotates the driving motor by the detection signal of the photocoupler (152).
[0071]
[0072] Figure 6 is a diagram illustrating a preferred embodiment of a power transmission structure of a compression cutting member. The compression cutting member (130) includes a drive roller and an idle roller. The waste paper cutting device of the embodiment of the present invention is configured such that the front upper door can be opened and closed around a rotating hinge, and an idle roller is formed on the front upper door.
[0073] When the front upper door is closed around the rotating hinge, the idle rollers provided in the front upper door press against the drive roller. In this state where the drive roller and idle roller are pressed, when the drive roller is rotated by the drive motor (not shown), the idle roller also automatically rotates.
[0074] The drive motor rotates the drive pulley (135), and the drive pulley rotates the driven pulley (136) via a belt (137). Various drive motors capable of supplying rotational force may be installed inside the rear case (114). The rotational force of the driven pulley (136) rotates the drive roller constituting the compression cutting member (130), and the rotation of the drive roller rotates the interlocked idle roller.
[0075] The paper cutting device is configured to open and close the front upper door around a rotating hinge, and an idle roller is formed on the front upper door. When the front upper door is closed around the rotating hinge, the idle roller contacts and presses the driving roller.
[0076] When the drive roller and the idle roller constituting the compression cutting member (130) are in contact and the drive roller rotates, the idle roller also automatically rotates.
[0077] In the paper cutting device of the present invention, when the front upper door (112) is opened to store paper (10) in roll form on the supply shaft, the idle roller is separated from the drive roller.
[0078] In the present invention, the compression cutting member (130) has the function of pulling out the roll-shaped waste paper (10) in a downward direction.
[0079]
[0080] Figure 7 is a diagram illustrating the driving roller and idle roller of the compression cutting member (130). In the present invention, the compression cutting member includes two rollers, one of which may be configured as a driving roller that transmits rotational force, and the other may be configured as an idle roller without rotational force.
[0081] The drive roller and idle roller can be configured as horizontal rollers or inclined rollers. Fig. 7 illustrates the horizontal roller (131) and the inclined roller (132) of the compression cutting member (130) spaced apart from each other. In the present invention, if the drive roller is configured as a horizontal roller, the idle roller becomes an inclined roller, and if the drive roller is configured as an inclined roller, the idle roller becomes a horizontal roller.
[0082] The compression cutting member (130) includes a horizontal roller (131) formed as a cylinder with the same diameter, and an inclined roller (132) formed in a cone shape that is engaged with the horizontal roller (131).
[0083] The compression cutting member (130) serves to transport the waste paper downward when rotating, and when stationary, it serves to enable one end of the cutting line (11, see FIG. 9) of the waste paper (10) to be cut first due to the tensile force generated by the waste paper winding member (150).
[0084] The inclined roller (132) is formed to be inclined at a predetermined angle and is composed of a compression cutting portion (133) that is combined in a compressed state with the horizontal roller (131), and a waste paper non-contact portion (134).
[0085]
[0086] Figure 8 is an explanatory drawing showing a state in which a horizontal roller (131) and an inclined roller (132) are interlocked.
[0087] The compression cutting member (130) is composed of a horizontal roller and an inclined roller, and the horizontal roller and the inclined roller are rotated or stopped by a driving motor while being interlocked with each other. The horizontal roller and / or the inclined roller are composed of an elastic body, and are characterized in that one end is compressed while the horizontal roller and the inclined roller are interlocked.
[0088] The horizontal roller and the inclined roller are arranged to hold the tissue paper between them. One end of the tissue paper is compressed, while the other end is not compressed. When the compression-cutting member stops rotating, the tissue paper winding member located below continues to rotate, causing the tissue paper to be subjected to a strong tensile force. At this time, the compressed side of the tissue paper is first broken at the cutting line. Of course, the cutting line on the non-compressed side of the tissue paper is also broken subsequently.
[0089] In the compression cutting section (133), the waste paper is positioned between the horizontal roller (131) and the inclined roller (132). One end of the waste paper is compressed, and the other end is not compressed.
[0090] The inclined roller (132) is made of soft rubber or synthetic resin so that it can be pressed against the horizontal roller (131). Elastic soft rubber or a soft elastic material is preferred. Of course, the horizontal roller can also be made of an elastic material.
[0091]
[0092] Fig. 9 is another embodiment of the compression cutting member of the present invention. The compression cutting member (141) is composed of a pair of interlocking rollers (142, 144), the first roller (142) is formed in a concentric circle, and roller protrusions (143) are formed on the surface of the first roller (142) at a regular interval so as to transport the waste paper (10). The second roller (144) is installed to be interlocked with the first roller (142), and the second roller (144) is composed of a third roller (144a) formed to half the length of the first roller (142) and a fourth roller (144b) on one side of the third roller (144a).
[0093] The first roller (142) is formed in a concentric shape with a certain diameter, and the second roller (144) that is engaged with the first roller (142) is configured with the same length and is configured with a third roller (144a) and a fourth roller (144b) that have different diameters. One of the third roller (144a) and the fourth roller (144b) is configured with a diameter so as to compress and press the toilet paper, and the other is configured so as not to compress the toilet paper. Of course, the rollers can be made elastic, and in particular, the roller protrusion (143) can be made elastic.
[0094] These compression cutting members (141) enable the tissue paper to remain compressed when releasing the tissue paper (10) or when cutting the tissue paper (10) while wrapping the tissue paper (10) around the tissue paper winding member (150).
[0095] The compression cutting member of Fig. 9 is characterized in that among the two rollers constituting the compression cutting member (130), one of the rollers includes a portion having a different diameter, thereby allowing the paper to be composed of a compressed portion and a non-compressed portion.
[0096]
[0097] Fig. 10 is a diagram illustrating a winding unit of a waste paper winding member according to a preferred embodiment of the present invention. The waste paper winding member (150) includes a winding unit (153) and a driving motor (151). The winding unit is configured in a form in which two straight bars (155, 156) are connected by a single connecting bar (154). When the driving motor (151) rotates, the waste paper supplied to the compression cutting member (130) is wound around the winding unit.
[0098] The waste paper winding member (150) is located inside the rotating space (120). The waste paper winding member functions to wind the waste paper (10) that is being unwound downward, and also provides tensile force to cut a certain amount of the wound waste paper. The winding unit (153) is installed to be rotatable by a driving motor (151) installed in the rear case (114).
[0099] The driving motor (151) rotates the winding unit (153) installed in the rotating space (120), and a photocoupler (152) is installed in the rotating space (120) to sense the presence of tissue (10). When tissue is recognized by the photocoupler (152), the driving motor rotates the winding unit, so that the tissue is wound around the winding unit. The driving motor rotates at a rotation speed set by the user.
[0100] The waste paper winding member (150) includes a driving motor (151) installed to rotate the winding unit (153, 157), and a winding unit (153) that rotates by the driving motor (151) to wind the waste paper (10) and cut the waste paper (10) pressed against the pressing cutting member (130).
[0101] The waste paper winding member (150) winds the waste paper (10) that is loosened to the lower side of the waste paper space (120) to enable cutting of the waste paper (10), and the winding unit (153) is installed to be rotatable by a driving motor (151) installed in the rear case (114).
[0102] The driving motor (151) rotates the winding unit (153) installed in the rotating space (120), and a photocoupler (152) that detects when the paper (10) is released by a certain length is installed in the rotating space (120).
[0103] The photocoupler (152) detects the loosened tissue (10) to a length of about 1.5 to 2 times the length of the connecting bar (154) of the winding unit (153), and the driving motor (151) rotates according to the detection signal of the photocoupler (152).
[0104] The automatic tissue cutting device of the present invention operates when the user presses a button or when a proximity sensor is installed so that the proximity sensor recognizes the presence of the user's hand when the user's hand is positioned around the proximity sensor, thereby operating the automatic tissue cutting device.
[0105] In addition, in the automatic tissue cutting device of the present invention, after the tissue is broken, the rotation of the winding unit is stopped at a position where the user can conveniently take out the broken tissue.
[0106] When the rotation of the winding unit is stopped while the virtual plane formed by the two straight bars and the connecting bar that constitute the winding unit is perpendicular to the ground, users with physical disabilities can more conveniently remove the broken tissue.
[0107] And, when the user takes out the broken tissue, the sensor recognizes the absence of the tissue, and the winding unit stops by moving to a horizontal state, that is, a state in which the plane formed by the two straight bars and the connecting bar is parallel to the ground, according to the control signal of the sensor.
[0108] Afterwards, when the user operates the device, the tissue paper sandwiched between the two rollers of the compression cutting member descends, and the descended tissue paper descends to a position near the center of the horizontal winding unit. By allowing the descending tissue paper to descend to a position near the center of the winding unit, the tissue paper can be easily wound on the winding unit without any mistakes.
[0109] When the paper is lowered through the two rollers of the press-cutting member, it is important to ensure that the paper is lowered to a position near the center of the winding unit. For this reason, when constructing the actual device, it is necessary to carefully adjust the position of the winding unit.

[0111] Fig. 11 is a diagram illustrating a slope winding unit of a waste paper winding member according to another preferred embodiment of the present invention. While the winding unit of Fig. 6 has two straight bars installed in parallel, the slope winding unit (157) is characterized in that the two straight bars are configured to form an inclined angle. The slope winding unit (157) has two straight bars (159, 160) connected by a connecting bar (158), and the two straight bars are configured to be non-parallel and form a predetermined inclined angle.
[0112] When toilet paper is wound on a slope winding unit that forms an inclined angle like this, some of the wound toilet paper is wound in contact with the straight bar, but some of the wound toilet paper is wound away from the straight bar without being in contact with the straight bar.
[0113] The reason why the tissue paper is wound in such a way that some parts of the tissue paper are in contact with the straight bar and other parts are not in contact with the straight bar is to enable the tissue paper to be cut sequentially.
[0114] When a slope winding unit is installed on a waste paper winding member, even when the compression cutting member (130) is composed of only horizontal rollers, one end of the cutting line (11, see Fig. 9) of the waste paper (10) may be cut first. In this case, the part where the waste paper is wound while in contact with the straight bar receives tensile force first, resulting in partial breakage.
[0115] After that, the cutting line is sequentially broken in the part where the tissue paper is not in contact with the straight bar.
[0116] The reason why one end of the cutting line is broken first and the other end is broken sequentially is to make it easier to cut the waste paper.
[0117] When the rotation of the compression cutting member stops and the paper is compressed on the compression cutting member, and the paper winding member continues to rotate, the paper is subjected to a tensile force, and the tensile force causes the paper to break first in the part where the paper is wound while in contact with the straight bar. In other words, the tensile force is concentrated on one end of the paper first, and then the other parts of the cutting line are sequentially broken.
[0118] Methods for causing sequential fractures in this manner include configuring the compression cutting member (130) with a horizontal roller and an inclined roller, or installing an inclined winding unit on the waste paper winding member. In an embodiment of the present invention, the two configurations can be performed separately or simultaneously.
[0119] The present invention is characterized in that it includes a sequential cutting means that, when the toilet paper is wound to an appropriate length in the winding unit, the rotation of the roller formed in the compression cutting member (130) is stopped, and only the toilet paper winding member is rotated so that one end of the cutting line of the toilet paper is broken first, and then the breaking proceeds along the entire cutting line of the toilet paper.
[0120] A representative example of a sequential cutting means is a compression cutting member (130) composed of a horizontal roller (131) formed in a concentric circle and an inclined roller having an inclined surface. The waste paper positioned between the horizontal roller and the inclined roller is compressed at one end and not compressed at the other end.
[0121] Another example of a sequential cutting means is a waste paper winding member (150) having an inclined winding unit. The inclined winding unit has two straight bars connected by a connecting bar, and the two straight bars have an inclined angle.
[0122]
[0123] Fig. 12 is a process diagram illustrating an automatic paper cutting method according to a preferred embodiment of the present invention. The cutting method of the automatic paper cutting device according to a preferred embodiment of the present invention comprises releasing the paper (10) installed on the supply shaft (117), lowering the paper sandwiched between two rollers of the compression cutting member (130), winding the paper by the paper winding member (150), and breaking the paper when a certain amount is wound around the paper winding member (150), and includes the following steps.
[0124] A roll-shaped waste paper (10) is inserted into the supply shaft (117), and the waste paper (10) is released through a driving motor (S10).
[0125] The waste paper (10) released from the supply shaft (117) is lowered while being sandwiched between two rollers of the compression cutting member (130) (S20).
[0126] (When using a sequential cutting means as a compression cutting member (130), the waste paper positioned between the horizontal roller and the inclined roller is configured so that compression occurs at one end and compression does not occur at the other end.)
[0127] The waste paper descending to the position of the compression cutting member (130) is detected through a photocoupler (151) installed in the rotating space (120) (S30).
[0128] In the photocoupler (151), the drive motor (151) of the paper winding member (150) is driven based on the detection of paper (10).
[0129] (If a photocoupler (152) is not used, the toilet paper (10) may be unwound to a length that can be wound around the winding unit, or the drive motor (151) of the toilet paper winding member (150) may be driven after the toilet paper has been unwound to a certain extent based on a certain period of time.)
[0130] The tissue paper (10) released from the compression cutting member (130) is wound by the winding unit driven by the driving motor of the tissue paper winding member (150) (S40).
[0131] (In the case where the sequential cutting means is a waste paper winding member (150) having a winding unit, the winding unit is made up of two straight bars connected by a connecting bar, and at least one of the two straight bars has an inclined angle.)
[0132] When a portion of the tissue paper is compressed in the compression cutting member (130), the rotation of the roller of the compression cutting member is stopped, and the tissue paper winding member (150) rotates to first cut one end of the cutting line (11) of the tissue paper, and then sequentially cut the remaining cutting lines.
