Description

Technical Field

[0001] This invention relates to the field of glass deep processing, and in particular to a glass deep processing towing system and its control method suitable for ultra-large spans. Background Technology

[0002] In glass production lines, glass often needs to be transported over extremely long spans, exceeding 100 meters. Existing conveyor systems struggle to meet the requirements for stable transport over such long distances. The existing glass production conveyor systems suffer from the following two problems:

[0003] (1) The existing glass conveying system uses only one drive motor as the driving source. When the span of the conveying is large, the length and weight of the conveyor belt also increase. A single drive motor cannot drive the entire conveyor belt forward. The torque of the drive motor is difficult to transmit to the part of the conveyor belt far away from the drive motor. As a result, the conveyor belt cannot operate normally.

[0004] (2) Existing glass conveying systems use two or more drive motors as the driving source. However, both drive motors are the main motors, meaning they start simultaneously during conveying. During conveying, part of the conveyor belt is in a taut state, while the other part remains slack. Continuous operation of the conveyor belt in this state poses a risk of breakage, and the glass being hoisted onto the conveyor belt is prone to misalignment and displacement. Misalignment and displacement of the glass during conveying can occur. For example, when the first piece of glass on the conveyor belt reaches its designated position, the second or third piece, etc., may not reach their designated positions due to the different states of the conveyor belt at different locations. This not only affects the production line working in conjunction with the conveyor belt and subsequent glass processing steps, but also makes adjacent glass pieces prone to collisions, affecting the surface quality of the glass and potentially causing breakage, posing a significant safety hazard. Summary of the Invention

[0005] To overcome at least one of the defects described in the prior art, one of the objectives of this invention is to provide a glass deep processing dragging system suitable for ultra-large spans. By setting a main motor and an auxiliary motor as driving sources, the main motor drags the ultra-large span annular conveyor, while the auxiliary motor drags the ultra-large span annular conveyor and pushes it towards the main motor. The main motor and the auxiliary motor work together to ensure that the ultra-large span annular conveyor can move smoothly.

[0006] The second objective of this invention is to provide a control method for a glass deep processing towing system with an ultra-large span. By having the main motor, auxiliary motor, and tensioning mechanism work together to continuously adjust the tension of the annular conveyor, the entire annular conveyor with an ultra-large span is in a tensioned state when the auxiliary motor is working. In this way, the glass suspended on the annular conveyor with an ultra-large span can be smoothly transported to the predetermined position, thereby improving production efficiency.

[0007] One of the objectives of this invention is achieved through the following technical solution:

[0008] A towing system for deep glass processing suitable for ultra-large spans includes:

[0009] The drive mechanism includes a drive wheel, an auxiliary wheel, a main motor, and an auxiliary motor. The main motor drives the drive wheel to rotate, and the auxiliary motor drives the auxiliary wheel to rotate.

[0010] The tensioning mechanism includes at least one tensioning pulley assembly;

[0011] A ring-shaped conveyor is fitted onto the drive wheel, auxiliary wheel, and tension wheel assembly.

[0012] In a preferred embodiment, the power of the main motor is greater than the power of the auxiliary motor.

[0013] In a preferred embodiment, the annular conveyor body is generally trapezoidal in shape, narrower at the top and wider at the bottom, and includes an upper section, a middle section and a lower section.

[0014] In a preferred embodiment, the glass deep processing towing system suitable for ultra-large spans includes a support mechanism, which includes at least two support pulleys. The two support pulleys are disposed at the upper two ends of the annular conveyor body, and the drive wheel and the auxiliary wheel are disposed at the lower two ends of the annular conveyor body.

[0015] In a preferred embodiment, at least one tensioning wheel assembly is disposed in the middle region of the upper section of the annular conveyor body;

[0016] The tensioning wheel assembly includes a first tensioning wheel, a second tensioning wheel, a third tensioning wheel, and a lifting mechanism. The first and second tensioning wheels are respectively located on both sides of the third tensioning wheel. The lifting mechanism drives the third tensioning wheel to move up and down relative to the first and second tensioning wheels.

[0017] In a preferred embodiment, the lifting mechanism is a cylinder mechanism, a hydraulic cylinder mechanism, or a lead screw slide mechanism.

[0018] In a preferred embodiment, the glass deep processing towing system suitable for ultra-large spans includes a detection device, and the output shaft of the main motor is equipped with the detection device to detect the magnitude of the force applied by the main motor.

[0019] In a preferred embodiment, the glass deep processing towing system suitable for ultra-large spans includes a detection device, and the output shaft of the auxiliary motor is equipped with the detection device to detect the magnitude of the force on the auxiliary motor.

[0020] The second objective of this invention is achieved by the following technical solution:

[0021] A control method for a glass deep processing towing system suitable for ultra-large spans, wherein the control steps of the aforementioned glass deep processing towing system suitable for ultra-large spans are as follows:

[0022] S100: Before the main motor and the auxiliary motor are started, the tensioning mechanism is adjusted so that the upper section of the annular conveyor is in a tensioned state;

[0023] S200: Start the main motor, at which time the auxiliary motor is stationary;

[0024] S300: The main motor works in conjunction with the tensioning mechanism to adjust the upper section and the lower section of the annular conveyor body to be in a tensioned state;

[0025] S400: Start the auxiliary motor, which rotates in the same direction as the main motor, driving the annular conveyor body to move upward.

[0026] In a preferred embodiment, the control method for a glass deep processing towing system with ultra-large spans further includes the following control steps:

[0027] S500: When the detection device detects that the force applied to the auxiliary motor is lower than the predetermined value, or when the detection device detects that the force applied to the main motor is higher than the predetermined value, it is determined that the lower section of the annular conveyor is in a relaxed state. At this time, the auxiliary motor stops working, and the main motor and the tensioning mechanism work together to tension the annular conveyor.

[0028] S600: When the detection device detects that the force on the auxiliary motor reaches a predetermined value, or when the detection device detects that the force applied by the main motor reaches a predetermined value, it determines that both the upper section and the lower section of the annular conveyor are in a tensioned state, and the auxiliary motor restarts.

In this way, the glass suspended on the annular conveyor body with a large span can be smoothly transported to the predetermined position, thereby improving production efficiency.

[0039] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0042] See Figures 1-2 This invention discloses a glass deep processing towing system suitable for ultra-large spans, comprising: a drive mechanism 10, which includes a drive wheel 11, an auxiliary wheel 12, a main motor 13, and an auxiliary motor 14, wherein the main motor 13 drives the drive wheel 11 to rotate and the auxiliary motor 14 drives the auxiliary wheel 12 to rotate; a tensioning mechanism 20, which includes at least one tensioning wheel assembly 21; and an annular conveyor 30, which is sleeved on the drive wheel 11, the auxiliary wheel 12, and the tensioning wheel assembly 21.

[0043] Therefore, by setting a main motor 13 and an auxiliary motor 14 as driving sources, the main motor 13 drags the ultra-large span annular conveyor body 30, and the auxiliary motor 14, while dragging the ultra-large span annular conveyor body 30, also pushes the ultra-large span annular conveyor body 30 towards the main motor 13. The main motor 13 and the auxiliary motor 14 work together to ensure that the ultra-large span annular conveyor body 30 can move smoothly.

[0044] In this embodiment of the invention, the power of the main motor 13 is greater than that of the auxiliary motor 14. When the main motor 13 is working, it starts first and conveys the annular conveyor body 30 upward. The larger the span of the annular conveyor body 30 and the greater its own weight, the greater the power of the main motor 13 should be. The power of the main motor 13 should be selected to ensure that the horizontal tension can be transmitted to the position of the auxiliary motor 14, while not causing deformation of the lower section 33 of the annular conveyor body 30.

[0045] Specifically, see Figure 1The main motor 13 is located on the left side of the glass deep processing towing system suitable for ultra-large spans, and the auxiliary motor 14 is located on the right side of the glass deep processing towing system suitable for ultra-large spans. Alternatively, the main motor 13 can be located on the right side of the glass deep processing towing system suitable for ultra-large spans, and the auxiliary motor 14 can be located on the left side of the glass deep processing towing system suitable for ultra-large spans. The relative positions of the main motor 13 and the auxiliary motor 14 are determined according to the actual situation and are not limited to this.

[0046] In this embodiment of the invention, the annular conveyor 30 is generally trapezoidal in shape, narrower at the top and wider at the bottom. The annular conveyor 30 includes an upper section 31, a middle section 32, and a lower section 33. The auxiliary motor 14 applies a dragging force to the middle section 32 of the annular conveyor 30 and a pushing force to the lower section 33 of the annular conveyor 30.

[0047] It should be noted that the span of the annular conveyor 30 refers to the center distance between the drive wheel 11 and the auxiliary wheel 12.

[0048] Specifically, the annular conveyor 30 includes two intermediate sections 32. The upper section 31 and the lower section 33 of the annular conveyor 30 are parallel to each other. The intermediate sections 32 of the two annular conveyors 30 are inclined relative to the upper section 31 and the lower section 33 of the annular conveyor 30, and the intermediate sections 32 of the two annular conveyors 30 are symmetrically arranged.

[0049] Specifically, the included angle between the middle section 32 and the lower section 33 of the annular conveyor 30 is 30°, 45° and 60°. If the included angle between the middle section 32 and the lower section 33 of the annular conveyor 30 is too large or too small, the conveying resistance of the annular conveyor 30 will increase.

[0050] Therefore, when the angle between the middle section 32 and the lower section 33 of the annular conveyor 30 is 30°, 45° and 60°, it is beneficial for the conveying of the annular conveyor 30.

[0051] In this embodiment of the invention, the glass deep processing towing system suitable for ultra-large spans includes a support mechanism 40. The support mechanism 40 includes at least two support pulleys 41, which are disposed at the upper ends of the annular conveyor body 30. The drive wheel 11 and the auxiliary wheel 12 are disposed at the lower ends of the annular conveyor body 30, and at least one tensioning wheel assembly 21 is disposed in the middle region of the upper section 31 of the annular conveyor body 30. The support pulleys 41 not only support the annular conveyor body 30 but also provide steering. Therefore, the tensioning mechanism 20, disposed in the middle region of the upper section 31 of the annular conveyor body 30, facilitates the tensioning of the upper section 31 without affecting the product conveying function of the lower section 33 of the annular conveyor body 30.

[0052] In this embodiment of the invention, the tensioning wheel assembly 21 includes a first tensioning wheel 211, a second tensioning wheel 212, a third tensioning wheel 213, and a lifting mechanism 214. The first tensioning wheel 211 and the second tensioning wheel 212 are respectively disposed on both sides of the third tensioning wheel 213. The lifting mechanism 214 drives the third tensioning wheel 213 to move up and down relative to the first tensioning wheel 211 and the second tensioning wheel 212.

[0053] Specifically, the support pulley 41, the first tensioning pulley 211, and the second tensioning pulley 212 are all set at the same height. The annular conveyor 30 is wrapped around the top of the first tensioning pulley 211 and the second tensioning pulley 212, and the annular conveyor 30 is wrapped around the bottom of the third tensioning pulley 213. Thus, when the third tensioning pulley 213 moves downward relative to the first tensioning pulley 211 and the second tensioning pulley 212, the third tensioning pulley 213 applies tension to the annular conveyor 30, thus tensioning the upper section 31 of the annular conveyor 30.

[0054] In this embodiment of the invention, the lifting mechanism 214 is a cylinder mechanism, a hydraulic cylinder mechanism, or a lead screw slide mechanism.

[0055] Specifically, when the lifting mechanism 214 is a pneumatic or hydraulic cylinder mechanism, the telescopic end of the pneumatic or hydraulic cylinder mechanism is connected to the rotating shaft of the third tensioning wheel 213. The telescopic movement of the pneumatic or hydraulic cylinder mechanism drives the lifting and lowering of the third tensioning wheel 213 via an electrical signal. This allows for automatic and real-time tension adjustment of the upper section 31 of the annular conveyor body 30 using the tensioning wheel assembly 21. The pneumatic or hydraulic cylinder mechanism is fixedly connected to the frame. The selection of the pneumatic or hydraulic cylinder mechanism and the flow rate adjustment determine the magnitude of the tension force.

[0056] In this embodiment of the invention, the glass deep processing towing system suitable for ultra-large spans includes a detection device. The output shaft of the main motor 13 is equipped with a detection device, which detects the magnitude of the force applied by the main motor 13.

[0057] Specifically, the detection device includes an ammeter, which is mounted on the output shaft of the main motor 13.

[0058] Specifically, when the ammeter detects the current parameter of the main motor 13, and then estimates the torque based on the performance curve of the main motor 13, when the output torque of the main motor 13 is equal to the predetermined value, it is considered that the tension of the main motor 13 can be transmitted to the auxiliary motor 14 through the annular conveyor 30. In this way, the annular conveyor 30 between the main motor 13 and the auxiliary motor 14 is in a taut state, that is, the lower section 33 of the annular conveyor 30 is in a taut state. At this time, the auxiliary motor 14 can be started.

[0059] In this embodiment of the invention, the annular conveyor 30 is an annular conveyor chain, an annular conveyor belt, or an annular conveyor rope.

[0060] It should be noted that the specific type of the annular conveyor 30 depends on the actual scenario.

[0061] In this embodiment of the invention, the glass deep processing towing system suitable for ultra-large spans includes a frame, with a drive mechanism 10, a tensioning mechanism 20, and a support mechanism 40 all connected to the frame. The frame provides support for the drive mechanism 10, the tensioning mechanism 20, and the support mechanism 40.

[0062] See Figure 5 This invention discloses a control method for a glass deep processing towing system suitable for ultra-large spans, comprising the following control steps based on the aforementioned glass deep processing towing system suitable for ultra-large spans:

[0063] S100: Before the main motor 13 and the auxiliary motor 14 are started, the tensioning mechanism 20 is adjusted so that the upper section 31 of the annular conveyor body 30 is in a tensioned state.

[0064] S200: Start the main motor 13, at which time the auxiliary motor 14 is stationary;

[0065] S300: The main motor 13 and the tensioning mechanism 20 work together to adjust the upper section 31 and the lower section 33 of the annular conveyor 30 to be in a tensioned state, that is, the entire annular conveyor 30 is in a tensioned state.

[0066] S400: Start the auxiliary motor 14. The auxiliary motor 14 rotates in the same direction as the main motor 13, driving the annular conveyor body 30 to move upward.

[0067] When the forces exerted by the main motor 13 and the auxiliary motor 14 on the lower section 33 of the annular conveyor 30 are unbalanced, the tension of the lower section 33 of the annular conveyor 30 changes. When the force on the lower section 33 of the annular conveyor 30 is lower than the threshold, the auxiliary motor 14 will automatically stop until the force on the lower section 33 of the annular conveyor 30 reaches the threshold before the auxiliary motor 14 will be restarted.

[0068] Therefore, in this embodiment of the invention, the control method for a glass deep processing towing system with an ultra-large span further includes the following control steps:

[0069] S500: When the detection device detects that the force applied by the main motor 13 is higher than the predetermined value, it determines that the lower section 33 of the annular conveyor 30 is in a relaxed state. At this time, the auxiliary motor 14 stops working, and the main motor 13 and the tensioning mechanism 20 work together to tension the annular conveyor 30.

[0070] S600: When the detection device detects that the force applied by the main motor 13 reaches the predetermined value, it determines that the upper section 31 and the lower section 33 of the annular conveyor 30 are both in a tensioned state, that is, the entire annular conveyor 30 is in a tensioned state, and at this time the auxiliary motor 14 starts working again.

[0071] The process by which the main motor 13 and the tensioning mechanism 20 work together to tension the annular conveyor body 30 is as follows:

[0072] When the tensioning mechanism 20 adjusts the upper section 31 of the annular conveyor 30 to a tensioned state, the main motor 13 starts working and rotates upward, driving the annular conveyor 30 to convey upward. Thus, the upper section 31 of the annular conveyor 30 returns to a relaxed state, and the tensioning mechanism 20 continues to adjust the upper section 31 of the annular conveyor 30 back to a tensioned state. This process is repeated until the lower section 33 of the annular conveyor 30 is also in a tensioned state. At this point, both the upper section 31 and the lower section 33 of the annular conveyor 30 are in a tensioned state.

[0073] Specifically, the state of the upper section 31 of the annular conveyor 30 is determined by the magnitude of the thrust of the lifting mechanism 214. Based on calculations for a large-span glass deep-processing towing system, when the upper section 31 of the annular conveyor 30 is in a tensioned state, the lifting mechanism 214 needs a thrust of 'a' to push the upper section 31 of the annular conveyor 30 downwards. Therefore, if the thrust required by the lifting mechanism 214 to push the upper section 31 of the annular conveyor 30 downwards is less than 'a', the upper section 31 of the annular conveyor 30 is determined to be in a relaxed state; if the thrust required by the lifting mechanism 214 to push the upper section 31 of the annular conveyor 30 downwards is equal to 'a', the upper section 31 of the annular conveyor 30 is determined to be in a tensioned state.

[0074] Thus, the tension of the lower section 33 of the annular conveyor 30, which is applicable to ultra-large span glass deep processing towing system, is achieved by detecting the torque of the main motor 13. There is no need to set a tensioning mechanism 20 in the lower section 33 of the annular conveyor 30, thus avoiding its impact on the product conveying of the lower section 33 of the annular conveyor 30.

[0075] Therefore, this invention utilizes the coordinated action of the main motor 13, auxiliary motor 14, and tensioning mechanism 20 to adjust the tension of the annular conveyor body 30. This ensures that the entire annular conveyor body 30 with its large span is under tension when the auxiliary motor 14 is operating, preventing slackness, deviation, or slippage. Consequently, the glass suspended in the lower section 33 of the annular conveyor body 30 can be smoothly transported to the predetermined position, ensuring the stable operation of the towing system and improving production efficiency.

[0076] Steps S500 and S600 of this invention are feedback adjustment steps, ensuring that the glass deep processing towing system suitable for ultra-large spans is always in a dynamic adjustment process. This guarantees that the annular conveyor 30 is always under tension during transport, further ensuring that each piece of glass transported by the annular conveyor 30 reaches the predetermined position. Simultaneously, the entire process is smooth, preventing collisions between the glass pieces transported by the annular conveyor 30. This glass deep processing towing system and its control method suitable for ultra-large spans are particularly suitable for industrial products, such as glass, that require suspended transport with large dimensions and long travel spans.

[0077] Example 2

[0078] Specifically, the detection device includes a torque sensor, which is located on the output shaft of the auxiliary motor 14.

[0079] Specifically, when the torque sensor detects that the torque of the auxiliary motor 14 exceeds a predetermined value, it is assumed that the tension of the main motor 13 can be transmitted to the auxiliary motor 14 through the annular conveyor 30. Thus, the annular conveyor 30 between the main motor 13 and the auxiliary motor 14 is in a taut state, meaning the lower section 33 of the annular conveyor 30 is taut. At this time, the auxiliary motor 14 can be started. It is understood that the magnitude of the aforementioned predetermined torque value is determined based on the specific power of the main motor 13, the power of the auxiliary motor 14, and the size and model of the annular conveyor 30, depending on the actual application scenario.

[0080] In this embodiment of the invention, the control method for a glass deep processing towing system with an ultra-large span further includes the following control steps:

[0081] S500: When the torque sensor detects that the torque of the auxiliary motor 14 is lower than the predetermined value, it is considered that the tension of the main motor 13 is not transmitted to the auxiliary motor 14 through the annular conveyor 30. In this case, the annular conveyor 30 between the main motor 13 and the auxiliary motor 14 is in a relaxed state, that is, the lower section 33 of the annular conveyor 30 is in a relaxed state. At this time, the auxiliary motor 14 stops working, and the main motor 13 and the tensioning mechanism 20 work together to tension the annular conveyor 30.

[0082] S500: When the torque sensor detects that the torque of the auxiliary motor 14 has reached the predetermined value, it is considered that the tension of the main motor 13 has been transmitted to the auxiliary motor 14 through the annular conveyor 30. Thus, the annular conveyor 30 between the main motor 13 and the auxiliary motor 14 is once again in a tensioned state, that is, the lower section 33 of the annular conveyor 30 is in a tensioned state. At this time, the auxiliary motor 14 starts working again.

[0083] Example 3

[0084] See Figures 3-4 Unlike Embodiment 1 of the present invention, in this embodiment, the glass deep processing towing system suitable for ultra-large spans includes at least three tensioning wheel sets 21. Two tensioning wheel sets 21 are located at the upper ends of the annular conveyor body 30, and at least one tensioning wheel set 21 is located in the middle region of the upper section 31 of the annular conveyor body 30. The drive wheel 11 and the auxiliary wheel 12 are located at the lower ends of the annular conveyor body 30. Thus, there is no need for a separate support mechanism 40. The tensioning wheel sets 21 located at the upper ends of the annular conveyor body 30 not only provide support and steering for the annular conveyor body 30, but also facilitate tensioning of the upper section 31 of the annular conveyor body 30. Compared to setting tensioning wheel sets 21 only in the middle region of the upper section 31 of the annular conveyor body 30, setting tensioning wheel sets 21 at both upper ends of the annular conveyor body 30 results in a larger tension adjustment area and higher efficiency. Therefore, the tensioning mechanism 20 is located in the upper section 31 of the annular conveyor body 30, which is beneficial for the tensioning of the upper section 31 of the annular conveyor body 30, and will not affect the function of conveying products in the lower section 33 of the annular conveyor body 30.

[0085] In this embodiment of the invention, the tensioning wheel assembly 21 includes a first tensioning wheel 211, a second tensioning wheel 212, a third tensioning wheel 213, and a lifting mechanism 214. The first tensioning wheel 211 and the second tensioning wheel 212 are respectively disposed on both sides of the third tensioning wheel 213. The lifting mechanism 214 drives the third tensioning wheel 213 to move up and down relative to the first tensioning wheel 211 and the second tensioning wheel 212.

[0086] Specifically, the first tensioning roller 211 and the second tensioning roller 212 are both set at the same height. The annular conveyor 30 is wrapped around the top of the first tensioning roller 211 and the second tensioning roller 212, and the annular conveyor 30 is wrapped around the bottom of the third tensioning roller 213. Thus, when the third tensioning roller 213 moves downward relative to the first tensioning roller 211 and the second tensioning roller 212, the third tensioning roller 213 applies tension to the annular conveyor 30, thus tensioning the upper section 31 of the annular conveyor 30.

[0087] Example 4

[0088] Unlike Embodiment 1 of the present invention, in this embodiment, when the lifting mechanism 214 is a screw-slide mechanism, the screw-slide mechanism includes a linear track, a screw rod, a slider, and a motor. The linear track and the screw rod are arranged parallel or nearly parallel. The slider is fitted onto both the linear track and the screw rod. The slider and the linear track are in sliding engagement, and the slider and the screw rod are in threaded engagement. The motor drives the screw rod to rotate, thereby causing the slider to slide along the linear track. The slider and the rotating shaft of the third tension wheel 213 are connected by a bearing. The forward or reverse rotation of the motor is controlled by an electrical signal to drive the lifting and lowering of the third tension wheel 213. Thus, the tension wheel assembly 21 can be used to automatically and in real-time adjust the tension of the upper section 31 of the annular conveyor 30.

[0089] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
