Description

TECHNICAL FIELD

The present invention relates to a powder material measuring rotary valve device, and more particularly, to a powder material measuring rotary valve device for mechanically and quantitatively measuring and sequentially discharging a powder material in the form of powder.

BACKGROUND ART

Recently, interest in energy storage technology has been increasing.

In general, as the field of application expands to home appliances such as mobile phones, camcorders, laptops, and desktop computers, and even energy of electric vehicles, efforts for research and development of electrochemical devices are becoming more and more specific.

Among various electrochemical devices, aqueous electrolyte-based lithium secondary batteries and capacitors that are applicable to fields requiring high output characteristics are attracting attention.

These electrochemical devices generally include a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode. In this case, the positive electrode and the negative electrode are generally manufactured by a method of applying an electrode active material slurry containing an electrode active material, a polymer binder, and a solvent dissolving the polymer binder for uniform mixing of the electrode active material to a surface of a current collector to form an electrode active material layer.

The electrode active material slurry may also further include a conductive material to improve electrical conductivity of the electrode. Meanwhile, in order to form a superior electrode, a dispersion material that uniformly disperses at least one of the electrode active material and the conductive material may be further included. This is because the shape of the electrode varies depending on the extent of dispersion of the electrode active material and the conductive material, and the performance of the battery varies accordingly.

Here, in case of an active material in the form of powder, when the active material is transferred from an input hopper to an individual storage hopper, a transfer of a quantitative amount of active material is required.

However, since measuring of the active material according to a conventional technology uses a screw that rotates intermittently, there is a problem in that the quantitative measurement of the active material is not performed clearly.

The conversion module 40 is disposed to be coaxial with or parallel to the first virtual axis. The conversion module 40 converts a rotational force to rotate the distribution module 20 and delivers the rotational force to the distribution module 20. In one embodiment of the present invention, the conversion module 40 is illustrated to be coupled to the shaft coupling module 30 so as to be coaxial with the first virtual axis. However, this is not limited thereto and when the shaft coupling module 30 is omitted, the conversion module 40 may be coupled to one side of the measuring housing 10.

The conversion module 40 may include a conversion body 41 disposed on one side of the measuring housing 10 and coupled to the shaft coupling module 30 or the measuring housing 10, the delivery drive shaft portion 43 rotatably coupled to the conversion body 41 coaxially with the first virtual axis and a drive connection shaft portion rotatably coupled to the conversion body 41 in a state that is coaxial with or parallel to the second virtual axis perpendicular to the first virtual axis and engaged with the delivery drive shaft portion 43. In this case, the delivery drive shaft portion 43 is detachably coupled to the distribution module 20 such that the delivery drive shaft portion 43 rotates with the distribution module 20.

The delivery drive shaft portion 43 may include a conversion connection portion 43-1 rotatably coupled to the conversion body 41, and a distribution coupling connection portion 43-3 extending coaxially to the conversion connection portion 43-1 so as to be inserted and supported in the distribution hole portion 21-1 provided in the distribution module 20.

In one embodiment of the present invention, the fixing coupling portion 43-6 is illustrated to pass through the fixing bracket 435 and be screw-coupled to the delivery drive shaft portion 43.

The power generation module 50 is disposed to be coaxial with, parallel to or intersecting the first virtual axis. The power generation module 50 generates a rotational force to rotate the distribution module 20 by an applied power source.

The rotation sensing module 60 is disposed to be coaxial with the first virtual axis. The rotation sensing module 60 detects a position of the unit discharge groove portion 22 in the measuring housing 10. In one embodiment of the present invention, the rotation sensing module 60 is illustrated to be coupled to the conversion module 40 coaxially with the first virtual axis. However, when the conversion module 40 is omitted, the rotation sensing module 60 may be coupled to the shaft coupling module 30 or the measuring housing 10.

In the method of measuring a powder material using the conventional rotary valve, there has been a problem in that when the operation is stopped due to a mechanical structural characteristic, a stop position of the unit discharge groove portion 22 cannot be accurately identified, and when a set measurement value is reached, the closure of the exit 12 side of the measuring housing 10 is inaccurate, resulting in a high fluctuation of the discharged amount.

However, according to the coupling relationship between the distribution module 20 and the rotation sensing module 60 and the detailed coupling state of the rotation sensing module 60 according to one embodiment of the present invention, the problem described above can be solved, and the stop position of the unit discharge groove portion 22 can be stabilized, and the closure of the exit 12 by the distribution module 20 can be simplified by clearly securing the communication between the entrance 11 and the unit discharge groove portion 22 and the communication between the exit 12 and the unit discharge groove portion 22 in a state of stopping the operation.

In addition, in the distribution module 20 according to one embodiment of the present invention, at least any one of the unit discharge groove portions 22 disposed on both sides of the unit discharge groove portion 22 in communication with the exit 12 does not communicate with the exit 12 in response to the communication of the unit discharge groove portion 22 with the entrance 11 and the communication of the unit discharge groove portion 22 with the exit 12, so that the closure and sealing of the exit 12 can be stably maintained, and an error with respect to the receiving amount of the powder material can be minimized in a space between a pair of detection wings 62-3 that are adjacent to each other and a unit receiving space of the powder material determined by the unit discharge groove portion 22.

The rotation sensing module 60 may include a sensing paddle 62 rotatably coupled to the conversion module 40 the shaft coupling module 30 or the measuring housing 10 via a paddle shaft portion 62-1 that is coaxial with the first virtual axis and a speed sensor 63 that detects the sensing paddle 62.

Here, the sensing paddle 62 may include a paddle body 62-2 coupled to the paddle shaft portion 62-1, and the detection wings 62-3 disposed at equal intervals on the paddle body 62-2 along an outer circumferential surface of the paddle body 62-2 corresponding to the unit discharge groove portion 22. Then, the speed sensor 63 may detect the amount of rotation of the distribution module as the speed sensor 63 detects the detection wings 62-3.

In the sensing paddle 62, either the paddle body 62-2 or the detection wings 62-3 may be provided with a default setting portion 62-4 to ensure that the unit discharge groove portion 22 remains stably open at the entrance 11 of the measuring housing 10, and to promote initialization of the distribution module 20.

The rotation sensing module 60 may further include a sensing body 61 coupled to the conversion module 40 the shaft coupling module 30 or the measuring housing 10 such that some or all of the sensing paddle 62 and the speed sensor are embedded therein.

With reference to a first coupled state, as illustrated in FIG. 6, the detection wings 62-3 may be formed to be bent away from an edge of the paddle body 62-2. Further, the speed sensor 63 is coupled to the sensing body 61 by being spaced apart outside an imaginary cylinder connecting the detection wings 62-3. Then, the speed sensor 63 is spaced apart from the paddle body 62-2 and disposed to face only the detection wings 62-3, so that the speed sensor 63 may intermittently detect the detection wings 62-3 depending on the rotation of the paddle shaft portion 62-1. Since a width of the detection wing 62-3 corresponding to a rotational direction of the paddle shaft portion 62-1 forms a predetermined first detection width, the identification of the position of the unit discharge groove portion 22 relative to the entrance 11 or exit 12 is made clear, and when the rotational force of the distribution module 20 is adjusted by a speed control module 70, a predetermined fixed quantity of powder material is stably received in the unit discharge groove portion 22.

With reference to a second coupled state, as illustrated in FIGS. 7 and 8, the detection wings 62-3 may be formed to protrude in a normal direction from a circumferential surface of the paddle body 62-2. Further, the speed sensor 63 is coupled to the sensing body 61 by being spaced apart outside an imaginary cylinder connecting the detection wings 62-3. Then, the speed sensor 63 is disposed to face both the circumferential surface of the paddle body 62-2 and the detection wings 62-3, so that the speed sensor 63 may intermittently detect the detection wings 62-3 depending on the rotation of the paddle shaft portion 62-1. Since the width of the detection wing 62-3 corresponding to the rotational direction of the paddle shaft portion 62-1 forms a predetermined second width that is smaller than the predetermined first detection width, the identification of the position of the unit discharge groove portion 22 relative to the entrance 11 or exit 12 is made clear, and when the rotational force of the distribution module 20 is adjusted by a speed control module 70, a predetermined fixed quantity of powder material is stably received in the unit discharge groove portion 22.

With reference to a third coupled state, as illustrated in FIG. 9, the detection wings 62-3 may be formed to protrude in a normal direction from the peripheral surface of the paddle body 62-2. Further, the speed sensor 63 is coupled to the sensing body 61 such that the speed sensor 63 faces a side surface of the paddle body 62-2. Then, the speed sensor 63 is disposed to face only the detection wings 62-3 in a direction parallel to the paddle shaft portion 62-1, so that the speed sensor 63 may intermittently detect the detection wings 62-3 depending on the rotation of the paddle shaft portion 62-1. Since the width of the detection wing 62-3 corresponding to the rotational direction of the paddle shaft portion 62-1 forms the predetermined first detection width, the identification of the position of the unit discharge groove portion 22 relative to the entrance 11 or exit 12 is made clear, and when the rotational force of the distribution module 20 is adjusted by the speed control module 70, a predetermined fixed quantity of powder material is stably received in the unit discharge groove portion 22.

With reference to the detailed coupling relationship of the rotation sensing module 60, the width of the detection wing 62-3 corresponding to the rotational direction of the paddle shaft portion 62-1, the time at which the speed sensor 63 detects the detection wings 62-3 using an interval between two adjacent detection wings 62-3, the time at which the rotational force generated by the power generation module 50 is adjusted, and the like may be adjusted, and the powder material received in the unit distribution groove portion 22 may be clearly adjusted.

The speed control module 70 regulates the rotational force generated by the power generation module 50 according to the position of the unit discharge groove portion 22 of the distribution module 20 detected in the rotation sensing module 60. A method of adjusting the rotational force in the speed control module 70 may be divided into a fine deceleration method and a receptive acceleration method. Then, through the rotation sensing module 60, the position of the unit discharge groove portion 22 may be detected, and the measured value of the powder material accumulated in the unit discharge groove portion 22 may be calculated according to the control of the speed control module 70, and a weight of the powder material per the unit discharge groove portion 22 may be converted to apply an error value according to precise measuring to a minimum.

According to the fine deceleration method, the speed control module 70 may include a detection identification portion 71 that identifies whether a detection signal is generated in response to the amount of rotation of the distribution module 20, a reception control portion 72 that maintains the rotational force generated by the power generation module 50 when the detection signal is not generated as an identification result of the detection identification portion 71, and an adjustment control portion 73 that decreases the rotational force generated by the power generation module 50 to a preset deceleration when the detection signal is generated as an identification result of the detection identification portion 71.

According to the receptive deceleration method, the speed control module 70 may include the detection identification portion 71 that identifies whether a detection signal is generated in response to the amount of rotation of the distribution module 20, the reception control portion 72 that maintains the rotational force generated by the power generation module 50 when the detection signal is generated as an identification result of the detection identification portion 71, and the adjustment control portion 73 that increases the rotational force generated by the power generation module 50 to a preset acceleration when the detection signal is not generated as an identification result of the detection identification portion 71.

In one example, since the speed control module 70 makes the rotational force of the power generation module 50 relatively smaller and causes the distribution module 20 to rotate relatively slower while the speed sensor 63 detects the detection wings 62-3 of the sensing paddle 62, the time in communication of the unit discharge groove portion 22 at the entrance 11 is relatively longer, and 85 to 90% of the unit discharge groove portion 22 at the entrance 11 maintains a communication state, so that the powder material may be sufficiently supplied to the unit discharge groove portion 22. Furthermore, since the speed control module 70 causes the rotational force of the power generation module 50 to be relatively greater and the distribution module 20 to rotate relatively faster when the speed sensor 63 does not detect the detection wings 62-3 of the sensing paddle 62, the time in communication of the unit discharge groove portion 22 at the entrance 11 becomes relatively shorter, and only a portion of the powder material delivered from the hopper (10 to 15% of the powder material received per the unit discharge groove portion 22) may be supplied to the unit discharge groove portion 22.

In another example, since the speed control module 70 causes the rotational force of the power generation module 50 to be relatively smaller and the distribution module 20 to rotate relatively slower while the speed sensor 63 detects the detection wings 62-3 of the sensing paddle 62, the powder material may be delivered to the two adjacent unit discharge groove portions 22, respectively. Furthermore, since the speed control module 70 causes the rotational force of the power generation module 50 to be relatively greater and the distribution module 20 to rotate relatively faster when the speed sensor 63 does not detect the detection wings 62-3 of the sensing paddle 62, the time in communication of the unit discharge groove portion 22 at the entrance 11 becomes relatively shorter, and one of the two adjacent unit discharge groove portions 22 is rapidly moved to the exit 12, while the other of the two adjacent unit discharge groove portions 22 has an increased communicating area with the entrance 11. However, only a portion of the powder material delivered from the hopper (10 to 15% of the powder material received per the unit discharge groove portion 22) may be supplied to the unit discharge groove portion 22.

In addition, the powder material inside the measuring housing 10 can be prevented from leaking to the outside by the opening and closing joint member 31, the rotation of the distribution module 20 can be made clear, and a flow according to the rotation of the distribution module 20 can be prevented.

In addition, the delivery drive shaft portion 43, which is the first virtual axis, can be stably supported by the shaft joint member 32, and the rotation of the delivery drive shaft portion 43 can be made smooth.

In addition, the rotational force can be adjusted by the conversion module 40 to stably rotate the distribution module 20 with a uniform rotational force.
