Description

Paper quantity measuring device using a magnetic turntable

[0001] The present invention relates to a paper remaining quantity measuring device using a magnetic rotating plate, and more specifically, to a paper remaining quantity measuring device using a magnetic rotating plate in which the magnetic rotating plate is connected to a paper transport device and rotates, and the rotational momentum is detected by a Hall sensor to measure the paper remaining quantity.

[0002] Office paper (e.g., A4 paper), widely used in companies and government offices, is packaged in units of hundreds of sheets. These small packages are then repackaged into bundles and supplied to consumers. When using the paper, consumers unpack the box, remove the individual wrappers, and load the paper into printers, copiers, and multifunction devices.

[0003] When using paper, consumers generally purchase it in box or small packages and do not constantly monitor the remaining amount; therefore, when the paper loaded in printers, copiers, and multifunction devices runs out, they only look for small or box-packaged paper to replenish the 부족. If there is no paper available or only a small amount remains at that point, they purchase or order it from online or offline stores. Users always purchase or order paper in box units to avoid experiencing paper shortages.

[0004] Accordingly, in the supply of office paper, there is a need for a solution that reduces the cost and waste of human and material resources caused by double packaging—such as packaging paper for small packages of hundreds of sheets or bundle-type box packaging—and reduces the inconvenience for consumers of having to constantly check the remaining quantity of paper to place orders or make purchases.

[0005]

[0006] Therefore, the purpose of the paper remaining quantity measuring device using a magnetic rotating plate according to the present invention, which solves the conventional problems described above, is to reduce the cost and resource waste caused by the double packaging of conventional small unit packaging and box packaging when supplying office paper, and to provide a convenient paper supply system that eliminates the need for consumers to constantly check the remaining quantity of paper.

[0007] Another objective of the paper remaining quantity measuring device using a magnetic rotating plate according to the present invention is to measure the remaining paper quantity in conjunction with a paper transport device.

[0008]

[0009] As an example of a paper remaining quantity measuring device using a magnetic rotating plate according to the present invention,

[0010] It comprises a motor, a feed screw connected to the shaft of the motor, a magnetic rotating plate connected to the top of the feed screw via a fixed hole and rotating by the rotation of the feed screw, magnets attached to the magnetic rotating plate at regular intervals, a paper support on which paper is placed and which is connected to the feed screw and capable of moving up and down by the rotation of the feed screw, and a control unit fixed within the device without vertical movement or rotational motion, which is equipped with a Hall sensor that converts the rotation of the magnets attached within the magnetic rotating plate into an electronic pulse value, calculates the pulse value, and converts the paper transport distance.

[0011] As another example of a paper remaining quantity measuring device using a magnetic rotating plate according to the present invention, the magnetic rotating plate has a circular structure and a plurality of magnets are attached thereto, and a fixing hole formed in the center of the magnetic rotating plate is fixed to a feed screw so that when the feed screw attached to the rotating shaft of the motor rotates, the magnetic rotating plate rotates together.

[0012] As another example of a paper remaining quantity measuring device using a magnetic rotating plate according to the present invention, when a certain amount of paper is removed, the control unit drives a motor to rotate the feed screw, the paper tray is raised, the magnetic flux rotating plate rotates, and the Hall sensor converts the magnetic value of the magnet into a pulse value, converts it into a distance value corresponding to the raising of the paper tray, and calculates the remaining amount of paper.

[0013]

[0014] The paper remaining quantity measuring device using a magnetic rotating plate according to the present invention has the effect of being simple in configuration, reducing costs, and increasing accuracy, because when the remaining paper quantity decreases, the paper support plate connected to the transfer screw moves upward by motor rotation, and at the same time, the magnetic rotating plate rotates to measure the remaining paper quantity.

[0015]

[0016] FIG. 1 is a configuration diagram of a paper remaining quantity measuring device using a magnetic rotating plate according to the present invention.

[0017] FIG. 2 is a plan view of a magnetic plate of a paper remaining quantity measuring device using a magnetic plate according to the present invention.

[0018]

[0019] The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0020] The present invention is not limited to the embodiments disclosed below but can be implemented in various different forms, and the embodiments provided are merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention.

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence of the invention, such detailed description is omitted.

[0022] FIGS. 1 and 2 illustrate embodiments of a paper remaining quantity measuring device using a magnetic rotating plate according to the present invention. The disclosed paper supply device automatically identifies and supplies the remaining quantity of office paper stacked within the device, thereby promoting convenience for consumers in office paper management and reducing costs and resource waste caused by conventional small packaging units and box packaging.

[0023] Referring to FIGS. 1 and 2, the paper feeder consists of a motor (10) and a feed screw (20) connected to the shaft of the motor (10). To measure the remaining amount of paper, the device is configured with a magnetic rotating plate (40) that rotates by the rotation of the feed screw (20) and is connected to the top of the feed screw (20) by a fixed hole (50), magnets (60) attached to the magnetic rotating plate (40) at regular intervals, a paper support (30) on which paper (not shown) is placed and which is connected to the feed screw (20) and can move up and down by the rotation of the feed screw (20), and a Hall sensor (80) that converts the rotation of the magnets (60) attached to the magnetic rotating plate (40) into an electronic pulse value, calculates the pulse value, and calculates the feed distance, and a control unit (70) that is fixed within the device without up-and-down movement or rotational movement.

[0024] The magnetic rotating plate (40) is designed to have a circular structure with a certain number of magnets (60) attached, and the fixing hole (50) formed in the center of the magnetic rotating plate (40) is fixed to the transfer screw (20), so that when the transfer screw (20) attached to the rotation axis of the motor (10) rotates, the magnetic rotating plate (40) rotates together. The material of the magnetic rotating plate (40) can be various types such as ABS, acrylic, PC, and aluminum, and it is designed as a semi-permanent structure using the method of utilizing magnets (60). The control unit (70) is composed of a PCB.

[0025] In the distance measurement method, when the magnetic rotating plate (40) rotates, the magnet (60) attached within the magnetic rotating plate (40) rotates, and the Hall sensor (80) located on the opposite side converts the magnetic value into an electronic pulse value and calculates the pulse value to detect the amount of rotation of the magnetic rotating plate (40). By doing so, the paper's upward transport distance is converted into a preset value, thereby measuring the remaining amount of paper. The position of the Hall sensor (80) is arranged to maintain a certain distance from the magnet (60) of the magnetic rotating plate (40) without contact. The output signal of the Hall sensor is linked with an MCU or logic element in the control unit (70) to calculate the distance value. Since the control unit (70) is electronic, a power supply unit must be configured together. The more magnets (60) of the magnetic rotating plate (40) there are, the higher the precision of the remaining amount of paper.

[0026] The operation method begins when the paper in the machine is full, with the paper tray (30) positioned at the bottom of the feed screw (20). When a certain amount of paper is removed, the control unit (70) drives the motor (10) to rotate the feed screw (20), causing the paper tray (30) to rise and the magnetic flux rotating plate (40) to rotate. The Hall sensor (80) converts the magnetic value of the magnet (60) into a pulse value and converts it into a distance value corresponding to the rise of the paper tray (30) to calculate the remaining amount of paper.

[0027] That is, when the remaining amount of paper decreases, the paper support plate (30) connected to the transfer screw (20) moves upward by the rotation of the motor (10), and the magnetic rotating plate (40) rotates.

[0028] In this invention, the magnet (60) of the magnetic rotating plate (40) and the Hall sensor (80) are connected to the paper transport device to measure the transport distance, so the configuration is simple, costs are reduced, and accuracy can be increased.

[0029] Although the present invention has been illustrated and described with preferred embodiments as described above, it is not limited to the embodiments described above, and it is obvious that various modifications and variations are possible within the scope of the technical concept of the present invention and the equivalent scope of the claims to be described below by those skilled in the art without departing from the spirit of the invention.
