Description

conveyor device

[0001] This application claims the benefit of priority based on Korean Patent Application No. 10-2025-0014039 dated February 4, 2025, and all contents disclosed in the document of said Korean patent application are incorporated herein as part of this specification.

[0002] The present invention relates to a conveyor device, and more specifically, to a conveyor device that automatically adjusts the tension of a conveyor belt and further provides a foreign matter removal function.

[0003]

[0004] Generally, conveyor devices are used in manufacturing plants or storage areas to transport manufactured or stored goods from one location to another.

[0005] These conveyor devices operate by continuously rotating a belt, mainly made of rubber, plastic, or metal, to carry objects. The tension applied to the belt varies depending on the weight of the conveyed object placed on the belt, or the tension changes as the belt contracts or expands due to the repeated operation of the conveyor device.

[0006] If the tension of the conveyor belt is too low, the belt may become loose and slip or not move properly, and conversely, if the tension is too high, there is a problem such as the belt stretching excessively or breaking, so the tension of the belt must be checked periodically.

[0007] In addition, when the conveyor device transports goods, foreign matter falling from the transported items may enter the interior of the conveyor device and cause problems such as accumulating or adhering to the inner surface of the conveyor belt.

[0008] In particular, when the conveyed material is an electrode, if the active material attached to the electrode detaches, it may accumulate inside the conveyor device or adhere to the inner surface of the frame, which may cause the device to become fixed or malfunction.

[0051] Embodiments that enable a person skilled in the art to easily implement the present invention are described in detail below with reference to the attached drawings. However, in describing the operating principles of preferred embodiments of the present invention in detail, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description is omitted.

[0052] In addition, the same reference numerals are used for parts having similar functions and operations throughout the drawings.

[0053]

[0054] Hereinafter, a conveyor device according to the present invention will be described.

[0055] FIG. 1 is a perspective view of a conveyor device according to the present invention viewed from one side, and FIG. 2 is a perspective view of a conveyor device according to the present invention viewed from the other side. Also, FIG. 3 is a drawing of the interior of a conveyor device according to the present invention viewed from one side, and FIG. 4 is an enlarged view for explaining a conveyor belt constituting a conveyor device according to the present invention.

[0056] Referring to FIGS. 1 to 4, the conveyor device according to the present invention comprises a conveyor belt (100), a frame part (200), a driving part (300), a roller part (400), a tension adjustment part (500), a foreign matter removal part (600), and a control part (700).

[0057] First, the conveyor belt (100) may be provided to receive a conveyed object and to transport the object to one side or the other side along the x-axis. For example, the conveyor belt (100) may be provided as a continuous belt made of rubber, plastic, metal, or other materials, but in the present invention, it may be provided as a chain belt in which a plurality of unit blocks (110) are connected by a plurality of connecting shafts (120).

[0058] A unit block (110) may be provided with a seating member (111) on which a transported object is placed, and a link member (112) that supports one side of the seating member (111). The seating member (111) may have a flat planar shape for seating the transported object. Additionally, when a plurality of unit blocks (110) are connected, the seating member (111) may have recessed and protruding areas repeatedly formed at both ends so that adjacent seating members (111) interlock with each other.

[0059] A link member (112) may be provided on one side of a seating member (111) and connected to an adjacent link member (112). For example, the link member (112) may be provided with two members spaced apart, such that the distance between the two members corresponding to one end is closer than the distance between the two members corresponding to the other end. At this time, the distance between the two members corresponding to the other end may be formed such that the one end can be inserted into the gap. Thus, when a plurality of unit blocks (110) are connected, the one end of the link member (112) adjacent to the other end of the link member (112) can be inserted.

[0060] Additionally, through holes may be formed at one end and the other end of the link member (112), and a plurality of unit blocks (110) may be connected by inserting a connecting shaft (120) through the through hole while the one end of the link member (112) adjacent to the other end of the link member (112) is inserted.

[0061] This conveyor belt (100) can be formed in the shape of an endless track in which a plurality of unit blocks (110) are connected in succession.

[0062] Since the conveyor belt (100) comprising a plurality of unit blocks (110) is obvious to a person skilled in the art, a more detailed description will be omitted.

[0063] The frame portion (200) may include a first frame (210) and a second frame (220) that form an internal space (S) for accommodating the remaining conveyor belt (100), excluding a portion of the conveyor belt (100) on which the conveyed material is placed. At this time, the first frame (210) may be a front frame and the second frame (220) may be a rear frame, but they may be opposite to each other.

[0064] The internal space (S) of the frame part (200) may accommodate a part of the conveyor belt (100), a part of the drive part (300), a roller part (400), a tension control part (500), and a part of the foreign matter removal part (600).

[0065] FIG. 5 is an enlarged view of a driving unit constituting a conveyor device according to the present invention viewed from one side, FIG. 6 is an enlarged view of a driving unit constituting a conveyor device according to the present invention viewed from the other side, and FIG. 7 is an exploded perspective view for explaining a handle unit of a driving unit constituting a conveyor device according to the present invention.

[0066] Referring to FIGS. 1 to 7 together, a driving unit (300) for driving a conveyor belt (100) to one side or the other 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).

[0067] The first sprocket (310) contacts the conveyor belt (100) and transmits a conveying driving force to the conveyor belt (100). The first sprocket (310) has teeth formed on its outer surface, and a protruding member (not shown) protruding in the front-rear direction (z-axis direction) from a link member (112) or a connecting shaft (120) protruding in the front-rear direction through a through hole is coupled to a plurality of grooves formed by the plurality of teeth, and the conveyor belt (100) is driven as the first sprocket (310) rotates.

[0068] This first sprocket (310) is connected to a second sprocket (320) by an axle member (not shown), and the second sprocket (320) can be connected to a third sprocket (330) through a chain member (340).

[0069] Here, the third sprocket (330) is connected to the rotation axis of the motor (350), so that as the motor (350) provides rotational driving force, the third sprocket (330) can be rotated to transmit a transfer driving force to the chain member (340). More specifically, the third sprocket (330) has teeth formed on its outer surface, and the chain member (340) is fastened to a plurality of grooves formed by the plurality of teeth, so that as the third sprocket (330) is rotated by the motor (350), a transfer driving force can be transmitted to the chain member (340).

[0070] Accordingly, the chain member (340) transmits the transfer driving force received from the third sprocket (330) to the second sprocket (320), and the second sprocket (320) can transmit the rotational driving force to the first sprocket (310) connected by the same rotation axis.

[0071] By transmitting this rotational driving force, the first sprocket (310) can transmit the rotational driving force provided from the motor (350) to the conveyor belt (100).

[0072] Additionally, the handle unit (360) may be provided with a connecting shaft (361), an extension member (362), and a handle portion (363) so as to be axially connected to the first sprocket (310) to manually rotate the first sprocket (310) when the rotational driving force of the motor (350) is interrupted.

[0073] The connecting shaft (361) may be provided to be inserted into the center of the first sprocket (310). At this time, the center of the first sprocket (310) is the same as the rotation axis of the first sprocket (310), and as the connecting shaft (361) rotates, the first sprocket (310) rotates together with it.

[0074] Additionally, the extension member (362) may be extended orthogonally from the end of the fastening shaft (361). For example, the extension member (362) may be extended along the xy-axis plane from the fastening shaft (361) which is extended in the z-axis direction.

[0075] The handle portion (363) may be extended orthogonally from the extension member (362) and may be extended in the same axial direction as the fastening axis (361). That is, the handle portion (363) may be extended in the z-axis direction in the same direction as the fastening axis (361) extending from the end of the extension member (362) which is extended along the xy-axis plane.

[0076] This handle unit (360) allows the first sprocket (310) to rotate as the operator rotates the fastening shaft (361) through the handle portion (363), thereby enabling the conveyor belt (100) to be driven for transport. Thus, the operator can manually drive the conveyor belt (100) to diagnose the condition of the conveyor belt (100) while the rotational driving force of the motor (350) is interrupted.

[0077] Additionally, the roller section (400) may include a first roller (410) and a second roller (420) to contact the conveyor belt (100) and change the conveying direction of the conveyor belt (100). Here, the first roller (410) and the second roller (420) are idlers and do not transmit direct driving force to the conveyor belt (100), but can support the conveyor belt (100) to provide tension or change the conveying direction of the conveyor belt (100).

[0078] To explain in more detail, first, the first roller (410) is exposed from the internal space (S) of the frame part (200) and is positioned between the conveyor belt (100) and the first sprocket (310) that are being transported from the upper side of the frame part (200), so that the conveyor belt (100) can change its transport direction to be transported to the upper side of the first sprocket (310) or the frame part (200).

[0079] Additionally, the first roller (410) may be provided to come into contact with the seating member (111) of the conveyor belt (100) so that the conveyor belt (100) maintains tension, and the first roller (410) may come into contact with the seating surface of the seating member (111), and a first friction member (411) may be provided on the outer surface. At this time, the first friction member (411) may be provided with an elastic material, for example, rubber or silicone material, to prevent damage to the seating surface of the seating member (111).

[0080] The second roller (420) is exposed from the internal space (S) of the frame part (200) and is positioned between the conveyor belt (100) and the tension control part (500) that are being transported from the upper side of the frame part (200), so that the conveyor belt (100) can change its transport direction to be transported to the tension roller (510) of the tension control part (500) or to the upper side of the frame part (200).

[0081] Additionally, the second roller (420) contacts the seating member (111) of the conveyor belt (100) to maintain tension on the conveyor belt (100), and the second roller (420) contacts the seating surface of the seating member (111), and a second friction member (421) may be provided on the outer surface. At this time, the second friction member (421) may be provided with an elastic material, such as rubber or silicone, to prevent damage to the seating surface of the seating member (111).

[0082] FIG. 8 is an enlarged view for explaining a tension control unit constituting a conveyor device according to the present invention, FIG. 9 is an enlarged view for explaining a cylinder part of a tension control unit constituting a conveyor device according to the present invention, and FIG. 10 is an internal cross-sectional view of a cylinder part constituting a conveyor device according to the present invention.

[0083] Referring to FIGS. 1 to 10, the tension adjustment unit (500) contacts a part of the conveyor belt (100) and performs the function of adjusting the tension of the conveyor belt (100). This tension adjustment unit (500) may include a tension roller (510), a cylinder unit (520), a sensor unit (530), and an air supply unit (540).

[0084] The tension roller (510) comes into contact with the conveyor belt (100) and provides pressure to the conveyor belt (100) to adjust the tension of the conveyor belt (100). At this time, the tension roller (510) comes into contact with the link member (112) of the conveyor belt (100) and can provide tension to the conveyor belt (100) by transmitting pressure provided by the cylinder part (520) to the conveyor belt (100).

[0085] The tension roller (510) can be provided to provide tension to the conveyor belt (100) and can be rotated by the conveying drive of the conveyor belt (100) so as not to interfere with the conveying drive of the conveyor belt (100).

[0086] The tension roller (510) can be connected to the cylinder part (520) through a fixed member (511) connected to the rotation axis (not shown) of the tension roller (510) so as not to interfere with the rotation of the tension roller (510). For example, the fixed member (511) extends from both ends of the rotation axis (not shown) of the tension roller (510) and is connected to the cylinder rod (521a) described later.

[0087] The cylinder part (520) coupled with the tension roller (510) provides forward or backward driving force to the tension roller (510). Here, the forward driving force of the cylinder part (520) is the driving force provided to the tension roller (510) in the 9 o'clock direction with reference to FIG. 8, and the backward driving force of the cylinder part (520) is the driving force provided to the tension roller (510) in the 3 o'clock direction.

[0088] This cylinder part (520) may include a cylinder unit (521) and a housing (522). The cylinder unit (521) includes a cylinder rod (521a) and a cylinder head (521b) so as to be coupled to a tension roller (510) by a fixing member (511), and the cylinder head (521b) may be placed in an internal space formed in the housing (522).

[0089] Additionally, the cylinder rod (521a) may extend from the cylinder head (521b) and be connected to the fixed member (511) of the tension roller (510). In this case, for example, the fixed member (511) may include a floating joint, and the floating joint may be connected to the cylinder rod (521a), so that even if the operating center of the cylinder part (520) and the operating center of the fixed member (511) do not coincide and eccentricity occurs, the eccentricity can be corrected to ensure smooth linear movement of the cylinder part (520).

[0090] The housing (522) has an internal space formed to enable reciprocating motion of the cylinder unit (521), and a part of the cylinder unit (521) can be accommodated in the internal space. In addition, this internal space can be separated into a first space (522a) and a second space (522b) by a cylinder head (521b).

[0091] At this time, the first space (522a) of the housing (522) may be formed on the other side partitioned from the cylinder head (521b) (3 o'clock direction in FIG. 10), and the second space (522b) may be formed on the one side where the cylinder rod (521a) extends from the cylinder head (521b) (9 o'clock direction in FIG. 10).

[0092] Meanwhile, the cylinder section (520) may be configured so 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 section (520) is provided with a pressure greater than the pressure provided to the second space (522b), and forward driving force can be transmitted to the cylinder unit (521) by the pressure difference between the pressure in the second space (522b) and the pressure in the first space (522a).

[0093] At this time, tension can be provided to the conveyor belt (100) as the tension roller (510) presses the conveyor belt (100) through the forward driving force of the cylinder part (520).

[0094] A sensor unit (530) is disposed on one side of the cylinder unit (520), and the sensor unit (530) may be a position sensing sensor that detects the position of the cylinder unit (521).

[0095] More specifically, the sensor unit (530) can detect the amount of tension provided to the conveyor belt (100) by using a magnet embedded in the cylinder unit (521), for example, the cylinder head (521b), to detect the position of the cylinder unit (521).

[0096] For example, the sensor unit (530) may be configured to detect the position of the cylinder unit (521) when the conveyor belt (100) is pressurized through the pressure provided by the cylinder unit (520). At this time, the position information signal of the cylinder unit (521) detected by the sensor unit (530) may be transmitted to the control unit (700) via wired or wireless means.

[0097] The control unit (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 control the cylinder unit (520) to provide pressure corresponding to the measured tension value.

[0098] For example, when the conveyor belt (100) is pressurized by the pressure provided by the cylinder unit (520), the control unit (700) can determine the tension of the conveyor belt (100) by comparing the position of the cylinder unit (521) with a preset position according to the pressure value, and can control the pressure of the cylinder unit (520) to provide a corresponding pressure when an error occurs.

[0099] For example, when the cylinder unit (520) pressurizes the conveyor belt (100), if the position of the cylinder unit (521) is advanced (9 o'clock direction according to FIG. 10) compared to a preset position according to the pressure value, the control unit (700) can determine that the conveyor belt (100) has become looser and increase the pressure of the cylinder unit (520).

[0100] In another example, when the cylinder unit (520) pressurizes the conveyor belt (100), if the position of the cylinder unit (521) is retracted (3 o'clock direction according to FIG. 10) from the preset position according to the pressure value, the control unit (700) can determine that the conveyor belt (100) is pulled further and reduce the pressure of the cylinder unit (520).

[0101] This control unit (700) can measure the tension amount of the conveyor belt (100) detected by the sensor unit (530) and adjust the driving force of the cylinder unit (520) through the air supply unit (540). The air supply unit (540) can adjust the pressure in the internal space of the housing (522) by injecting air into the internal space of the housing (522).

[0102] At this time, the air supply unit (540) is connected to the first space (522a) of the housing (522) and can regulate the air pressure of the first space (522a) by supplying or discharging air to the first space (522a). Here, the air supply unit (540) can automatically regulate the air pressure of the first space (522a) as an air pressure regulator.

[0103] Meanwhile, the second space (522b) of the housing (522) is not connected to the air supply unit, so the first space (522a) can always have a greater pressure than the second space (522b). Due to the pressure of the first space (522a), the cylinder unit (521) is driven forward to measure the tension of the conveyor belt (100) in opposition to the conveyor belt (100).

[0104] However, it is not limited to this, and the second space (522b) is connected to an air supply unit, and the air supply unit connected to the second space (522b) maintains the cylinder unit (521) by adjusting the air pressure of the second space (522b) so that it is lower than the air pressure of the first space (522a), and when the cylinder unit (521) needs to be moved backward according to the tension of the conveyor belt (100), the pressure of the cylinder unit (521) can be adjusted so that the air pressure of the second space (522b) is increased or the air supply is cut off to maintain it equal to the air pressure of the first space (522a) so that the cylinder unit (521) can be moved backward.

[0105] FIG. 11 is an internal cross-sectional view of a conveyor device for explaining a foreign matter removal unit constituting a conveyor device according to the present invention, and FIG. 12 is an enlarged view for explaining a first suction unit constituting a conveyor device according to the present invention. FIG. 13 is an enlarged view for explaining a second suction unit constituting a conveyor device according to the present invention, FIG. 14 is an enlarged view for explaining an air injection unit constituting a conveyor device according to the present invention, and FIG. 15 is an enlarged view for explaining a vibration providing unit constituting a conveyor device according to the present invention.

[0106] Referring to FIGS. 1 to 15, the foreign matter removal unit (600) may be provided to remove foreign matter from the internal space (S) of the conveyor belt (100) and / or frame unit (200). This foreign matter removal unit (600) may include a suction unit (610), an air injection unit (620), a vibration providing unit (630), and a dust collection chamber (640).

[0107] The suction unit (610) may include a first suction unit (611), a second suction unit (612), and a dust collection unit (613) that are positioned in the internal space (S) of the frame unit (200) and suck air and / or foreign matter toward the conveyor belt (100).

[0108] The first suction unit (611) may be provided to be exposed from the internal space (S) of the frame portion (200) and to suck air and / or foreign matter toward the conveyor belt (100) being transported from the upper side of the frame portion (200). That is, the first suction unit (611) is positioned in the internal space (S) and is provided to suck air and / or foreign matter toward the conveyor belt (100) being transported from the upper side of the frame portion (200), so as to suck up foreign matter falling off from the transported material placed on the conveyor belt (100).

[0109] Additionally, the second suction unit (612) may be provided to suck air and / or foreign matter toward the conveyor belt (100) being transported in the internal space (S) of the frame portion (200). That is, the second suction unit (612) may be provided to suck air and / or foreign matter toward the conveyor belt (100) that has been transported into the internal space (S) with foreign matter attached that was not sucked by the first suction unit (611).

[0110] Additionally, the second suction unit (612) is located relatively lower than the position where the first suction unit (611) is provided, so that when foreign matter falls off from a transported object placed on the upper side of the conveyor belt (100), it can suck up and remove foreign matter that was not sucked into the first suction unit (611).

[0111] A dust collection unit (613) may be connected to the first suction unit (611) and the second suction unit (612) to collect foreign matter sucked from the first suction unit (611) and the second suction unit (612). This dust collection unit (613) may provide a negative pressure state toward the conveyor belt (100) to suck air and / or foreign matter through the first suction unit (611) and the second suction unit (612).

[0112] That is, the dust collection unit (613) may be a known suction means (not shown), such as a vacuum pump, that provides suction power to suck up foreign matter through the first suction unit (611) and the second suction unit (612), and as another example, it may be a chamber connected to a known suction means (not shown), such as a vacuum pump.

[0113] Such dust collection units (613) may be positioned on the outside of the frame portion (200). For example, the dust collection unit (613) may be positioned on the outer surface of the second frame (220) and connected to the first suction unit (611) and the second suction unit (612) through a through hole formed in the second frame (220).

[0114] Additionally, the air injection unit (620) is positioned in the internal space (S) of the frame portion (200) and may be configured to inject air toward the conveyor belt (100). The air injection unit (620) can receive air through the aforementioned air supply unit (540) and inject air toward the conveyor belt (100), and can remove foreign matter settled or attached to the conveyor belt (100) through the injected air.

[0115] At this time, it is preferable that the air injection unit (620) be positioned to inject air toward the conveyor belt (100) being transported from the lower side among the conveyor belts (100) being transported in the internal space (S). Accordingly, when the air injection unit (620) injects air toward the conveyor belt (100), by injecting air toward the lower side, foreign matter settled or attached to the conveyor belt (100) can be displaced downward and collected in the dust collection chamber (640) located at the bottom of the frame part (200).

[0116] A vibration providing unit (630) may be positioned on the outside of the frame portion (200) to provide vibration to the frame portion (200). By providing vibration from the outside of the frame portion (200) toward the inside, this vibration providing unit (630) can remove foreign matter attached to the inner surface of the frame portion (200). For example, the vibration providing unit (630) may be positioned on the second frame (220).

[0117] At this time, the vibration providing unit (630) can provide vibration to the frame part (200) when no material is placed on the conveyor belt (100), because if the vibration is provided to the frame part (200) while the material is placed on the upper side of the conveyor belt (100), more foreign matter may be generated from the placed material. More preferably, the vibration providing unit (630) can provide vibration to the frame part (200) when power is supplied to the conveyor device but the conveyor belt (100) is not being driven for transport.

[0118] Here, the vibration providing unit (630) may be an air vibrator and may be configured to provide vibration by a rotating turbine that revolves internally by receiving air from the air supply unit (540). However, it is not limited thereto, and the vibration providing unit (630) may be provided as various vibrators obvious to a person skilled in the art, such as an electric vibrator that provides vibration by electricity, a hydraulic vibrator that provides vibration using hydraulic pressure, or a motor vibrator that provides vibration by a motor.

[0119] The dust collection chamber (640) forms a space communicating with the internal space (S) of the frame portion (200) to collect foreign matter removed from the inner surface of the frame portion (200) by the vibration providing unit (630), and can be located at the bottom of the frame portion (200).

[0120] The dust collection chamber (640) may have a size capable of accommodating the entire lower portion of the frame portion (200) so as to collect at least most of the foreign matter moving downward from the internal 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 be provided with a size greater than or equal to the cross-sectional size cut along the xz-axis plane of the frame portion (200).

[0121] This dust collection chamber (640) can collect foreign matter removed by the vibration providing unit (630) as well as foreign matter removed by the aforementioned air injection unit (620).

[0122] Meanwhile, as described above, the control unit (700) can measure the amount of tension of the conveyor belt (100) detected through the sensor unit (530) of the tension control unit (500) and control the driving force of the cylinder unit (520) through the air supply unit (540), and can also perform overall control so that each component of the conveyor device according to the present invention can perform its function normally.

[0123] This control unit (700) may be implemented in the form of hardware or software, or in a combined form of hardware and software. The control unit (700) may be implemented in the form of a computing device (computation device) such as a microprocessor, but is not limited thereto and may be implemented in various forms that are obvious to those skilled in the art.

[0124] Additionally, the control unit (700) can determine the amount of tension received through the tension control unit (500) in real time and transmit a signal of tension abnormality of the conveyor belt (100) to the operator, and can display such a signal on an equipment monitor (e.g., a display unit) or transmit it to the operator's terminal (e.g., a mobile phone).

[0125] FIG. 16 is a drawing illustrating the state in which tension is removed from a conveyor belt constituting a conveyor device according to the present invention.

[0126] Referring to FIGS. 1 to 16 together, when the control unit (700) receives a signal indicating an abnormal tension of the conveyor belt (100), the operator can remove the amount of tension provided to the conveyor belt (100) by removing the pressure of the cylinder unit (520) while the drive unit (300) is stopped through the control unit (700).

[0127] Accordingly, the operator can adjust the length of the conveyor belt (100) that has been lowered with tension removed. For example, the operator can open the dust collection chamber (640) located at the bottom of the frame part (200) to expose the conveyor belt (100) to the outside, and can respond to the tension abnormality signal of the conveyor belt (100) by adjusting the length of the conveyor belt (100) by removing or increasing one or more unit blocks (110) of the exposed conveyor belt (100).

[0128]

[0129] As specific parts of the present invention have been described in detail above, it is obvious to those skilled in the art that such specific descriptions are merely preferred embodiments and do not limit the scope of the invention, and that various changes and modifications are possible within the scope and spirit of the invention, and that such variations and modifications fall within the scope of the appended claims.
