Description

Technical Field

[0001] This application claims the benefit of priority to Korean Patent Application No. 10-2025-0014039, filed on February 4, 2025, the disclosure of which is incorporated herein by reference in its entirety.

[0002] This invention relates to conveying equipment, and more specifically, to conveying equipment capable of automatically adjusting the tension of a conveyor belt and removing foreign objects. Background Technology

[0003] Typically, conveyor systems are used in manufacturing plants or places where goods are loaded and stored to move manufactured or stored goods from one location to another.

[0004] Conveying equipment primarily operates by continuously rotating a belt made of rubber, plastic, metal, or similar materials to transport objects. The tension applied to the belt varies depending on the weight of the object being conveyed and resting on the belt, or the belt may contract or expand due to the repeated operation of the conveying equipment, thus altering the belt tension.

[0005] If the conveyor belt tension is too low, the belt may become loose, slip, or fail to move properly. Conversely, if the tension is too high, the belt may be overstretched or break. Therefore, it is necessary to check the belt tension regularly.

[0006] In addition, when the conveyor transports objects, foreign objects that fall from the transported objects may enter the interior of the equipment and accumulate or adhere to the inner surface of the conveyor belt.

[0007] In particular, when the object being transported is an electrode, if the active material detaches from the electrode, the active material may not only accumulate in the transport device, but may also adhere to the inner surface of the frame, which may lead to equipment blockage or malfunction.

[0047] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that these preferred embodiments can be readily implemented by those skilled in the art. However, in describing the operating principles of the preferred embodiments of the present invention, detailed descriptions of known functions and configurations incorporated herein may obscure the subject matter of the invention, and such detailed descriptions will be omitted.

[0048] Furthermore, throughout the accompanying drawings, the same reference numerals will be used to refer to parts that perform similar functions or operations. Throughout the specification, where a part is referred to as being connected to another part, a part may not only be directly connected to the other part, but also indirectly connected to the other part via other parts. Additionally, including a predetermined element does not mean excluding other elements, but rather means that such elements may be included unless otherwise specified.

[0049] The transmission device according to the present invention will be described below.

[0050] Figure 1 This is a perspective view of the transmission device according to the invention as viewed from one side, and Figure 2 This is a perspective view of the transmission device according to the present invention as viewed from another side. Additionally, Figure 3 This is a view showing the interior of the transmission device according to the invention as viewed from one side, and Figure 4 This is an enlarged view illustrating the conveyor belt constituting the conveying device according to the present invention.

[0051] Reference Figures 1 to 4 The conveying device according to the present invention includes a conveyor belt 100, a frame portion 200, a drive portion 300, a roller portion 400, a tension adjustment portion 500, a foreign matter removal portion 600, and a controller 700.

[0052] First, the conveyor belt 100 can be configured to allow objects to be transported to sit on the conveyor belt 100 and to transport objects along the X-axis to one side or the other. For example, the conveyor belt 100 can be a continuous belt made of rubber, plastic, metal or other materials; however, in this invention, the conveyor belt can be a chain belt configured such that multiple unit blocks 110 are connected to each other via multiple connecting shafts 120.

[0053] Unit block 110 may include a seating member 111 on which the transported object sits and a connecting member 112 configured to support one surface of the seating member 111. The seating member 111 may have a flat planar shape, allowing the transported object to sit on it. Additionally, the seating member 111 may have repeatedly formed recessed and protruding regions at its two ends, such that adjacent seating members 111 may interlock with each other when multiple unit blocks 110 are connected to each other.

[0054] A connecting member 112 may be disposed on one surface of the seating member 111 for connection to adjacent connecting members 112. For example, a connecting member 112 may include two members spaced apart from each other, wherein the distance between two members corresponding to one end may be less than the distance between two members corresponding to the other end. In this case, the distance between two members corresponding to the other end may be configured such that one end can be inserted between the two members corresponding to the other end. Therefore, when multiple unit blocks 110 are connected to each other, one end of the connecting member 112 can be inserted into the other end of its adjacent connecting member 112.

[0055] Additionally, a through hole may be formed in each of one end and the other end of the connecting member 112, and when the connecting shaft 120 is inserted through the through hole with one end of the connecting member 112 inserted into the other end of the adjacent connecting member 112, a plurality of unit blocks 110 may be connected to each other.

[0056] The conveyor belt 100 can be formed into a circular track shape in which multiple unit blocks 110 are continuously connected to each other.

[0057] The conveyor belt 100, which includes multiple unit blocks 110, is known to those skilled in the art; therefore, a more detailed description thereof will be omitted.

[0058] The frame portion 200 may include a first frame 210 and a second frame 220, which are configured to form an internal space S in which the remaining portion of the conveyor belt 100, except for the portion where the conveyor belt 100 houses the object being conveyed, is received. In this case, the first frame 210 may be a front frame and the second frame 220 may be a rear frame, or the first frame 210 may be a rear frame and the second frame 220 may be a front frame.

[0059] A portion of the conveyor belt 100, some components of the drive section 300, some components of the roller section 400, the tension adjustment section 500, and the foreign matter removal section 600 can be accommodated in the internal space S of the frame section 200.

[0060] Figure 5 This is an enlarged view of the drive portion constituting the transmission device according to the present invention, when viewed from one side. Figure 6 This is an enlarged view of the drive portion constituting the transmission device according to the invention when viewed from the other side, and Figure 7 This is an exploded perspective view illustrating the handle unit that constitutes the drive portion of the transmission device according to the present invention.

[0061] Reference Figures 1 to 7 The drive section 300 configured to drive the conveyor belt 100 to one side or the other side may include a first sprocket 310, a second sprocket 320, a third sprocket 330, a chain member 340, a motor 350, and a handle unit 360.

[0062] The first sprocket 310 contacts the conveyor belt 100 and transmits the driving force for conveying to the conveyor belt 100. The first sprocket 310 has teeth formed on its outer peripheral surface and is connected to a plurality of recesses formed by the plurality of teeth by a protruding member (not shown) extending in the front-back direction (Z-axis direction) from the connecting member 112 or by a connecting shaft 120 protruding in the front-back direction through a through hole, and the conveyor belt 100 is driven when the first sprocket 310 rotates.

[0063] The first sprocket 310 can be connected to the second sprocket 320 via a shaft member (not shown), and the second sprocket 320 can be connected to the third sprocket 330 via a chain member 340.

[0064] Here, the third sprocket 330 is connected to the rotating shaft of the motor 350, and when the motor 350 provides a driving force for rotation, the third sprocket 330 can rotate to transmit the driving force for transmission to the chain member 340. More specifically, the third sprocket 330 has teeth formed on its outer peripheral surface, and the chain member 340 is fastened to a plurality of recesses formed by the plurality of teeth. Therefore, when the third sprocket 330 is rotated by the motor 350, the third sprocket can transmit the driving force for transmission to the chain member 340.

[0065] Therefore, the chain member 340 can transmit the driving force for transmission received from the third sprocket 330 to the second sprocket 320, and the second sprocket 320 can transmit the driving force for rotation to the first sprocket 310 connected to the second sprocket 320 via the same axis of rotation.

[0066] Due to the transmission of the driving force for rotation, the first sprocket 310 can transmit the driving force for rotation provided by the motor 350 to the conveyor belt 100.

[0067] Additionally, the handle unit 360 may be configured to allow manual rotation of the first sprocket 310 in the event of a disruption in the supply of driving force for rotation from the motor 350, and may include a fastening shaft 361 axially connected to the first sprocket 310, an extension member 362, and a handle portion 363.

[0068] The fastening shaft 361 can be inserted into the center of the first sprocket 310. In this case, the center of the first sprocket 310 is the same as the axis of rotation of the first sprocket 310, and therefore the first sprocket 310 also rotates when the fastening shaft 361 rotates.

[0069] Additionally, the extension member 362 can extend vertically from the end of the fastening shaft 361. For example, the extension member 362 can extend along the XY plane from the fastening shaft 361 extending in the Z-axis direction.

[0070] The handle portion 363 can extend vertically from the extension member 362 and can extend in the same axial direction as the fastening shaft 361. That is, the handle portion 363 can extend from the end of the extension member 362, which extends along the XY plane, in the Z-axis direction, which is the same as the direction in which the fastening shaft 361 extends.

[0071] The handle unit 360 allows the first sprocket 310 to rotate and drive the conveyor belt 100 when the operator uses the handle portion 363 to rotate the fastening shaft 361. Therefore, the operator can manually drive the conveyor belt 100 to diagnose the condition of the conveyor belt 100 even when the supply of driving force for rotation from the motor 350 is interrupted.

[0072] The roller section 400 may include a first roller 410 and a second roller 420 configured to contact the conveyor belt 100 to change the conveying direction of the conveyor belt 100. Here, each of the first roller 410 and the second roller 420 is an idler wheel and does not transmit direct driving force to the conveyor belt 100, but can support the conveyor belt 100 to provide tension to the conveyor belt or change the conveying direction of the conveyor belt 100.

[0073] More specifically, the first roller 410 may be located between the conveyor belt 100 exposed from the interior space S of the frame portion 200 and conveyed above the frame portion 200 and the first sprocket 310, to change the conveying direction of the conveyor belt 100, such that the conveyor belt is conveyed to the first sprocket 310 or conveyed above the frame portion 200.

[0074] Additionally, the first roller 410 may contact the seating member 111 of the conveyor belt 100 to maintain the tension of the conveyor belt 100. The first roller 410 may contact the seating surface of the seating member 111 and may have a first friction member 411 disposed on the outer peripheral surface of the first roller 410. In this case, the first friction member 411 may be made of an elastic material, such as rubber or silicone, to prevent damage to the seating surface of the seating member 111.

[0075] The second roller 420 can be located between the conveyor belt 100, which is exposed from the interior space S of the frame section 200 and conveyed above the frame section 200, and the tension adjustment section 500, to change the conveying direction of the conveyor belt 100, so that the conveyor belt is conveyed to the tension roller 510 of the tension adjustment section 500 or conveyed above the frame section 200.

[0076] Additionally, the second roller 420 may contact the seating member 111 of the conveyor belt 100 to maintain the tension of the conveyor belt 100. The second roller 420 may contact the seating surface of the seating member 111 and may have a second friction member 421 disposed on the outer peripheral surface of the second roller 420. In this case, the second friction member 421 may be made of an elastic material, such as rubber or silicone, to prevent damage to the seating surface of the seating member 111.

[0077] Figure 8 This is an enlarged view illustrating the tension adjustment section constituting the conveying device according to the present invention. Figure 9 This is an enlarged view illustrating the cylinder portion constituting the tension adjusting section of the conveying device according to the present invention, and Figure 10 This is an internal cross-sectional view of the cylinder portion constituting the conveying device according to the present invention.

[0078] Reference Figures 1 to 10 The tension adjusting section 500 contacts a portion of the conveyor belt 100 and performs the function of adjusting the tension of the conveyor belt 100. The tension adjusting section 500 may include a tension roller 510, a cylinder section 520, a sensor unit 530, and an air supply section 540.

[0079] The tension roller 510 contacts the conveyor belt 100 and applies pressure to the conveyor belt 100 to adjust the tension of the conveyor belt 100. In this case, the tension roller 510 may contact the connecting member 112 of the conveyor belt 100 and may provide tension to the conveyor belt 100 by transmitting the pressure supplied by the cylinder section 520 to the conveyor belt 100.

[0080] The tension roller 510 can provide tension to the conveyor belt 100 and can rotate under the drive of the conveyor belt 100 so as not to interfere with the drive of the conveyor belt 100.

[0081] The tension roller 510 can be connected to the cylinder portion 520 via a fixing member 511 connected to the rotating shaft (not shown) of the tension roller 510 so as not to interfere with the rotation of the tension roller 510. For example, the fixing member 511 extends from both ends of the rotating shaft (not shown) of the tension roller 510 and is connected to the cylinder rod 521a, which will be described later.

[0082] The cylinder portion 520, connected to the tension roller 510, provides a forward or backward driving force to the tension roller 510. Here, based on... Figure 8 The forward driving force of the cylinder section 520 is provided to the tension roller 510 in the 9 o'clock direction, and the backward driving force of the cylinder section 520 is provided to the tension roller 510 in the 3 o'clock direction.

[0083] The cylinder portion 520 may include a cylinder unit 521 and a housing 522. The cylinder unit 521 includes a cylinder rod 521a connected to the tension roller 510 via a fixing member 511 and a cylinder head 521b, wherein the cylinder head 521b may be disposed in the internal space of the housing 522.

[0084] Additionally, the cylinder rod 521a can extend from the cylinder head 521b and connect to the fixing member 511 of the tension roller 510. In this case, for example, the fixing member 511 includes a floating connection, which can be connected to the cylinder rod 521a, so that even if eccentricity occurs due to the operating center of the cylinder portion 520 and the operating center of the fixing member 511 not coinciding with each other, the eccentricity can be compensated to ensure smooth linear movement of the cylinder portion 520.

[0085] The housing 522 may have an internal space to enable the reciprocating motion of the cylinder unit 521, and a portion of the cylinder unit 521 may be received within this internal space. Furthermore, the internal space may be divided into a first space 522a and a second space 522b by the cylinder head 521b.

[0086] In this case, the first space 522a of the housing 522 can be formed on the other side separated by the cylinder head 521b. Figure 10 (at the 3 o'clock position), and the second space 522b of the housing can be formed on the side where the cylinder rod 521a extends from the cylinder head 521b ( Figure 10 (The 9 o'clock direction).

[0087] Simultaneously, the cylinder portion 520 can be configured such that the cylinder unit 521 is driven forward and backward by the pressure difference between the first space 522a and the second space 522b. More specifically, the cylinder portion 520 can be configured such that the pressure provided in the first space 522a is higher than the pressure provided in the second space 522b, and the forward driving force is transmitted to the cylinder unit 521 due to the pressure difference between the second space 522b and the first space 522a.

[0088] At this time, the tension roller 510 can press the conveyor belt 100 due to the forward driving force of the cylinder part 520, thereby providing tension to the conveyor belt 100.

[0089] The sensor unit 530 may be disposed on a side surface of the cylinder portion 520, wherein the sensor unit 530 may be a position detection sensor configured to detect the position of the cylinder unit 521.

[0090] More specifically, the sensor unit 530 can detect the amount of tension supplied to the conveyor belt 100 by using a magnet embedded in the cylinder unit 521, such as the cylinder head 521b, to detect the position of the cylinder unit 521.

[0091] For example, sensor unit 530 can be configured to detect the position of cylinder unit 521 when the pressure provided by cylinder section 520 presses the conveyor belt 100. At this time, the position information signal of cylinder unit 521 detected by sensor unit 530 can be transmitted to controller 700 via wired or wireless connection.

[0092] The controller 700 can measure the tension value applied to the conveyor belt 100 based on the position information of the cylinder unit 521 detected by the sensor unit 530, and can execute control such that the cylinder part 520 provides pressure corresponding to the measured tension value.

[0093] For example, when the pressure provided by the cylinder section 520 presses the conveyor belt 100, the controller 700 can determine the tension of the conveyor belt 100 by comparing the position of the cylinder unit 521 with a position preset according to the pressure value, and can control the pressure of the cylinder section 520 so that if an error occurs, the corresponding pressure is provided.

[0094] More specifically, for example, if the position of the cylinder unit 521 is further forward than a preset position corresponding to the pressure value when the conveyor belt 100 is pressed by the cylinder section 520 (in... Figure 10 If the controller 700 determines that the conveyor belt 100 has become looser (in the 9 o'clock position), it can increase the pressure of the cylinder section 520.

[0095] Additionally, as another example, if the position of the cylinder unit 521 is further back than the preset position corresponding to the pressure value when the conveyor belt 100 is pressed by the cylinder section 520 (in... Figure 10 If the controller 700 is located at the 3 o'clock position, it can determine that the conveyor belt 100 has become tighter and can reduce the pressure of the cylinder section 520.

[0096] The controller 700 can measure the tension of the conveyor belt 100 detected by the sensor unit 530, and adjust the driving force of the cylinder section 520 via the air supply section 540. The air supply section 540 can inject air into the internal space of the housing 522 to regulate the pressure inside the housing 522.

[0097] At this time, the air supply section 540 can be connected to the first space 522a of the housing 522, and supply air to or exhaust air from the first space 522a to regulate the air pressure in the first space 522a. Here, the air supply section 540 can be an electric regulator capable of automatically controlling the air pressure in the first space 522a.

[0098] Meanwhile, the second space 522b of the housing 522 is not connected to the air supply section, and therefore the first space 522a can always have a higher pressure than the second space 522b. The cylinder unit 521 can be driven forward by the pressure in the first space 522a to measure the tension of the conveyor belt 100 when facing the conveyor belt 100.

[0099] However, the invention is not limited thereto. The second space 522b can be connected to an air supply section, and the air supply section connected to the second space 522b can adjust the air pressure in the second space 522b to be lower than the air pressure in the first space 522a, so that the cylinder unit 521 is driven forward. In addition, when the cylinder unit 521 needs to move backward based on the tension of the conveyor belt 100, the air supply section can adjust the pressure of the cylinder section 520, so that the cylinder unit 521 moves backward by increasing the air pressure in the second space 522b or stopping the air supply to be equal to the air pressure in the first space 522a.

[0100] Figure 11 This is an internal cross-sectional view of the conveying device according to the present invention, illustrating the foreign matter removal portion constituting the conveying device, and Figure 12 This is an enlarged view illustrating the first suction unit constituting the conveying device according to the present invention. Additionally, Figure 13 This is an enlarged view illustrating the second suction unit constituting the conveying device according to the present invention. Figure 14 This is an enlarged view illustrating the air jet unit constituting the conveying device according to the present invention, and Figure 15This is an enlarged view illustrating the vibration supply unit constituting the transmission device according to the present invention.

[0101] Reference Figures 1 to 15 The foreign object removal section 600 can be configured to remove foreign objects from the internal space S of the conveyor belt 100 and / or the frame section 200. The foreign object removal section 600 may include a suction section 610, an air jet unit 620, a vibration supply unit 630, and a dust collection chamber 640.

[0102] The suction section 610 may include a first suction unit 611, a second suction unit 612, and a dust collection unit 613 disposed in the internal space S of the frame section 200 to suction air and / or foreign matter from the conveyor belt 100.

[0103] The first suction unit 611 can be configured to suction air and / or foreign objects from the conveyor belt 100, which is exposed from the interior space S of the frame portion 200 and conveyed above the frame portion 200. That is, the first suction unit 611 can be configured to suction air and / or foreign objects from the conveyor belt 100, which is exposed from the interior space S and conveyed above the frame portion 200, thereby suctioning foreign objects from the conveyed object seated on the conveyor belt 100.

[0104] Additionally, the second suction unit 612 can be configured to suction air and / or foreign objects from the conveyor belt 100 conveyed in the internal space S of the frame portion 200. That is, the second suction unit 612 can be configured to suction air and / or foreign objects from the conveyor belt 100 conveyed to the internal space S and having foreign objects that have not been suctioned by the first suction unit 611.

[0105] Furthermore, the second suction unit 612 can be positioned lower than the first suction unit 611. Therefore, when a foreign object detaches from a conveyed object sitting on the conveyor belt 100, the second suction unit 612 can suction and remove the foreign object that was not suctioned by the first suction unit 611.

[0106] The dust collection unit 613 can be connected to the first suction unit 611 and the second suction unit 612 to collect foreign objects sucked up by the first suction unit 611 and the second suction unit 612. The dust collection unit 613 can provide a negative pressure state to the conveyor belt 100, so that the first suction unit 611 and the second suction unit 612 suck up air and / or foreign objects.

[0107] In other words, the dust collection unit 613 can be a known suction device (not shown), such as a vacuum pump, configured to provide suction force so that the first suction unit 611 and the second suction unit 612 can suction foreign objects. As another example, the dust collection unit can be a chamber connected to a known suction device (not shown), such as a vacuum pump.

[0108] The dust collection unit 613 can be disposed on the outside of the frame portion 200. For example, the dust collection unit 613 can be disposed on the outer surface of the second frame 220 and can be connected to the first suction unit 611 and the second suction unit 612 through through holes formed in the second frame 220.

[0109] Additionally, the air injection unit 620 can be disposed within the internal space S of the frame portion 200 and can be configured to inject air toward the conveyor belt 100. The air injection unit 620 can receive air from the air supply portion 540 and inject air toward the conveyor belt 100. The injected air can remove foreign matter deposited on or attached to the conveyor belt 100.

[0110] At this time, it is desirable that the air jetting unit 620 be configured to jet air toward the conveyor belt 100 that is being conveyed in the internal space S from its lower portion. Therefore, when the air jetting unit 620 jets air toward the conveyor belt 100, the air can be jetted downwards, thereby allowing foreign objects deposited on or attached to the conveyor belt 100 to fall downwards and be collected in the dust collection chamber 640 located at the bottom of the frame portion 200.

[0111] The vibration supply unit 630 can be disposed outside the frame portion 200 to provide vibration to the frame portion 200. The vibration supply unit 630 can remove foreign matter adhering to the inner surface of the frame portion 200 by providing vibration from the outside to the inside of the frame portion 200. For example, the vibration supply unit 630 can be disposed on the second frame 220.

[0112] When the vibration supply unit 630 provides vibration to the frame section 200 while the object being conveyed is seated on the conveyor belt 100, more foreign matter may be generated from the seated object. Therefore, the vibration supply unit can provide vibration to the frame section 200 even when no object being conveyed is seated on the conveyor belt 100. More preferably, the vibration supply unit 630 can provide vibration to the frame section 200 when power is supplied to the conveying equipment but the conveyor belt 100 is not being conveyed.

[0113] Here, the vibration providing unit 630 may be an air vibrator and may be configured to provide vibration via an internal turbine configured to rotate by means of air supplied from the air supply section 540. However, the invention is not limited thereto, and it will be apparent to those skilled in the art that the vibration providing unit 630 may be configured as any of a variety of vibrators, such as an electric vibrator configured to provide vibration using electricity, a hydraulic vibrator configured to provide vibration using hydraulic pressure, and a motor vibrator configured to provide vibration using a motor.

[0114] The dust collection chamber 640 has a space communicating with the interior space S of the frame portion 200 to collect foreign objects removed from the inner surface of the frame portion 200 by the vibration supply unit 630, and may be located at the bottom of the frame portion 200.

[0115] The dust collection chamber 640 may have dimensions capable of accommodating the entire lower portion of the frame portion 200 in order to collect at least a majority of foreign objects moving downward from the interior space S of the frame portion 200. That is, one end of the dust collection chamber 640 connected to the lower portion of the frame portion 200 may have a dimension equal to or greater than the cross-sectional dimension of the frame portion 200 cut along the XZ plane.

[0116] The dust collection chamber 640 can collect not only foreign objects removed by the vibration supply unit 630, but also foreign objects removed by the air jet unit 620.

[0117] Meanwhile, as described above, the controller 700 can measure the amount of tension of the conveyor belt 100 detected by the sensor unit 530 of the tension adjustment section 500, and adjust the driving force of the cylinder section 520 via the air supply section 540. Furthermore, the controller can perform overall control, ensuring that each component of the conveying device according to the present invention operates normally.

[0118] The controller 700 can be implemented in hardware, in software, or in a combination of hardware and software. The controller 700 can be implemented as a computing device (arithmetic device) such as a microprocessor, but is not limited thereto, and can be implemented in any of the various forms that will be apparent to those skilled in the art.

[0119] Additionally, the controller 700 can determine the amount of tension received from the tension regulating section 500 in real time and transmit an abnormal tension signal of the conveyor belt 100 to the operator. The signal can be displayed on a device monitor (e.g., a display) or transmitted to the operator's terminal (e.g., a mobile phone).

[0120] Figure 16 This is a view illustrating the state of tension being removed from the conveyor belt constituting the conveying device according to the invention.

[0121] Reference Figures 1 to 16 When the controller 700 receives a tension abnormality signal from the conveyor belt 100, the operator can release the pressure in the cylinder section 520 while the controller 700 stops the operation of the drive section 300 to remove the amount of tension supplied to the conveyor belt 100.

[0122] Therefore, the operator can adjust the length of the conveyor belt 100, which sags downward due to the removal of tension. For example, the operator can open the dust collection chamber 640 located at the bottom of the frame portion 200 to expose the conveyor belt 100 to the outside, and can adjust the length of the conveyor belt 100 in response to a tension abnormality signal of the conveyor belt 100 by removing or increasing the number of unit blocks 110 of the exposed conveyor belt 100 by one or more.

[0123] Although the specific details of the invention have been described in detail, those skilled in the art will understand that the detailed description only discloses preferred embodiments of the invention and therefore does not limit the scope of the invention. Therefore, those skilled in the art will understand that various changes and modifications are possible without departing from the scope and concept of the invention, and it will be apparent that such changes and modifications fall within the scope of the appended claims.
