Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and in particular to a transfer system and a control method for the transfer system. Background Technology

[0002] In a material transfer system that requires two transfer machines to dock and transfer materials, the two transfer machines are spaced apart and each includes a housing and a transfer device located inside the housing. The transfer device has a buffer flow channel. The docking flow channels of the two transfer machines extend out of the housing to dock, so as to realize the transfer of materials from one transfer machine to the flow channel of the other transfer machine.

[0003] However, because the docking channels of the two transfer machines connect at the gap between them, occupying the space between the two machines, maintenance personnel cannot pass through the space between them and can only rely on the ladder to enter the next work station for maintenance work, which brings inconvenience to the maintenance work. Moreover, to cross the taller transfer machine, the ladder also needs to be erected at a higher height, which increases the risk factor for maintenance personnel climbing the ladder and poses a high safety hazard.

[0004] Therefore, there is an urgent need for a transfer system and a control method for the transfer system to solve the above-mentioned problems in the prior art. Summary of the Invention

[0088] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0089] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0090] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0091] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0092] In this embodiment, the term "and / or" is merely a description of the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0093] In the embodiments of the present invention, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0094] like Figure 1The diagram shown is a structural schematic of the transfer system provided in this embodiment. The transfer system includes two transfer machines 1000 spaced apart, through which materials 2000 can be transferred. For example, materials 2000 on one transfer machine 1000 can be transferred to the other transfer machine 1000. The transfer system provided in this embodiment allows maintenance personnel to pass through the passage between the two transfer machines 1000 without climbing ladders, reducing the difficulty of maintenance work, improving maintenance efficiency, and reducing safety risks during maintenance operations.

[0095] Specifically, see Figure 1 and Figure 2 The transfer machine 1000 provided in this application embodiment includes a housing 1 and a transfer device 2. Each housing 1 of the two transfer machines 1000 has a through opening 11 on its side facing each other. The housing 1 has space inside for installing the transfer device 2, and the through opening 11 extends through the side wall of the housing 1. The transfer device 2 is movably disposed in the housing 1 between a first position and a second position, and moves through the through opening 11. The first position is the position where the transfer devices 2 of the two transfer machines 1000 are connected, and the second position is the position where the transfer devices 2 of the two transfer machines 1000 are separated; the distance between the transfer devices 2 of the two transfer machines 1000 in the second position is greater than or equal to a distance threshold.

[0096] In the aforementioned transfer system, by setting the transfer device 2 to be movable within the housing 1, when it is necessary to transfer material 2000 between two transfer machines 1000, the transfer devices 2 of the two transfer machines 1000 are controlled to move to the first position, so that they are connected to transfer the material 2000 on one transfer device 2 to the other transfer device 2. When maintenance personnel need to pass through, the transfer devices 2 of the two transfer machines 1000 are controlled to move from the first position to the second position, so that the transfer devices 2 of the two transfer machines 1000 are separated from each other, thereby clearing a passage for maintenance personnel to pass through. This allows maintenance personnel to pass through the passage between the two transfer machines 1000 without climbing ladders, reducing the difficulty of maintenance work, improving maintenance work efficiency, and reducing safety risks during maintenance work.

[0097] The aforementioned spacing threshold can be set to allow a single maintenance worker to pass through. For example, the spacing threshold is greater than or equal to 0.35m. For instance, the spacing threshold could be 0.35m, 0.4m, 0.45m, 0.5m, 0.55m, 0.6m, etc., but is not limited to the values ​​listed.

[0098] In some embodiments of this application, the transfer device 2, when in the second position, does not extend beyond the through opening 11, so that the passage size allowing maintenance personnel to pass between the two transfer machines 1000 is maximized. For example, see... Figure 1If the distance L between the two transfer machines 1000 is 0.5m, then when the transfer device 2 moves to the second position, a maintenance passage with a width of 0.5m can be formed between the two transfer machines 1000 for maintenance personnel to pass through.

[0099] In some embodiments, the transfer device 2 in the second position can be flush with the through opening 11. In other embodiments, the transfer device 2 in the second position can be located on the side of the through opening 11 closer to the interior of the housing 1. That is, in this case, the transfer device 2 is completely inside the housing 1 and there is a gap between it and the through opening 11. This can, to some extent, prevent maintenance personnel from accidentally touching the transfer device 2 when passing through the passage between the two transfer machines 1000, thereby improving safety.

[0100] For example, the distance between the two transfer machines 1000 is 0.5m. When the transfer device 2 moves to the second position, it is exactly flush with the through opening 11. On the one hand, it can form the maximum width maintenance passage between the two transfer machines 1000, that is, a maintenance passage of 0.5m. On the other hand, it can shorten the moving stroke of the transfer device 2, thereby helping to reduce the size of the transfer machine 1000 to a certain extent.

[0101] like Figure 3 As shown, in some embodiments of this application, the transfer machine 1000 further includes a first drive mechanism 3. The housing of the first drive mechanism 3 is connected to the housing 1, and the output end of the first drive mechanism 3 is connected to the transfer device 2 via a transmission connection. The first drive mechanism 3 is used to drive the transfer device 2 to move linearly relative to the housing 1, so that the transfer device 2 can switch between a first position and a second position. By setting the first drive mechanism 3, the automated and intelligent control of the transfer device 2 can be realized, making it easier to move the transfer device 2 to a second position that avoids the maintenance passage, thus improving the convenience of maintenance operations.

[0102] In other embodiments of this application, the entire transfer device 2 can also be manually moved between the first and second positions. For example, a slide rail can be provided inside the housing 1, and the transfer device 2 slides in conjunction with the slide rail, allowing manual switching of the position of the transfer device 2. Furthermore, a locking mechanism can be provided inside the housing 1 to lock the transfer device 2 when it moves to the first or second position, thus keeping the transfer device 2 in the first or second position.

[0103] In this embodiment, two transfer machines 1000 are set apart along the first direction, so the moving direction of the transfer device 2 is also the first direction, that is, the driving direction of the first driving mechanism 3 is the first direction, so that the transfer device 2 extends or retracts through the through-hole 11 along the first direction.

[0104] like Figure 3 and Figure 4As shown, the first direction is the X direction in the figure. Figure 4 The state shown is the state when the transfer device 2 is in the first position. The height direction of the transfer machine 1000 is the Z direction, and the width direction is the Y direction, wherein the X, Y, and Z directions are perpendicular to each other.

[0105] like Figure 3 and Figure 5 As shown, in some embodiments of this application, the first drive mechanism 3 is a linear drive mechanism, such as a cylinder, hydraulic cylinder, electric push rod, etc., and its output end is provided with a connecting component 4. The connecting component 4 is used to connect the output end of the first drive mechanism 3 and the transfer device 2. Combined with... Figure 6 The housing 1 has a first through-hole 51 on the support base 5. The first drive mechanism 3 is installed at the bottom of the support base 5, and the transfer device 2 is slidably connected to the upper part of the support base 5. The connecting component 4 passes through the first through-hole 51 and is connected to the transfer device 2. Placing the transfer device 2 and the first drive mechanism 3 at the top and bottom of the support base 5 respectively allows for better utilization of the space within the housing 1, resulting in a more rational and compact structural layout. The first through-hole 51 and the connecting component 4 facilitate the transmission connection between the first drive mechanism 3 and the transfer device 2.

[0106] In other embodiments, the first driving mechanism 3 may also include a motor, a gear, and a rack. The rack is disposed within the bearing base 5, the gear is connected to the output end of the motor, and the motor housing is slidably connected to the bearing base 5 and connected to the bottom of the transfer device 2, thus enabling the transfer device 2 to move. Alternatively, the first driving mechanism 3 may also include a motor and a lead screw and nut mechanism, which can also drive the transfer device 2 to move linearly.

[0107] Specifically, see Figure 5 The connecting component 4 includes a first connecting frame 41 and a second connecting frame 42. The first connecting frame 41 includes a connecting plate 411 and support plates 412 disposed at both ends of the connecting plate 411. The output end of the first driving mechanism 3 is provided with a floating joint 31. The second connecting frame 42 engages with the floating joint 31 and is connected to the connecting plate 411. The support plate 412 extends away from the second connecting frame 42, and the end of the support plate 412 away from the connecting plate 411 is connected to the transfer device 2. By providing the floating joint 31, the eccentricity angle between the output end of the first driving mechanism 3 and the driven transfer device 2 can be absorbed, reducing the transmission accuracy requirements between the two and ensuring safety and stability during transmission. The connecting plate 411 and the support plates 412 at both ends roughly form a U-shaped first connecting frame 41, which expands the support area of ​​the connecting component 4 for the transfer device 2, improves the stability when driving the transfer device 2 to move, and also helps to improve the force balance.

[0108] Furthermore, the second connecting frame 42 is roughly L-shaped plate structure. Its first end is fixedly connected to the connecting plate 411 of the first connecting frame 41, and the second end is provided with a bayonet 421. The floating joint 31 is provided with a recessed slot. The second end of the second connecting frame 42 engages with the slot on the floating joint 31 through the bayonet 421, making the connection convenient and stable.

[0109] See Figure 7 , Figure 8 as well as Figure 9 A guide rail 61 is provided on the support base 5, and the guide rail 61 extends along the moving direction of the transfer device 2, that is, along the first direction. A slider 62 is provided at the bottom of the transfer device 2, and the slider 62 slides in cooperation with the guide rail 61. When the transfer device 2 moves between the first position and the second position, the slider 62 slides along the guide rail 61 to improve the moving accuracy and stability of the transfer device 2 and avoid movement deviation.

[0110] Furthermore, two guide rails 61 are provided on the support base 5 along the Y direction, and sliders 62 are provided on the bottom of the transfer device 2 at the positions corresponding to the two guide rails 61. By providing two guide rails 61, the stability of the transfer device 2 during movement and the guiding accuracy of the transfer device 2 can be further increased, effectively preventing the transfer device 2 from moving off-center.

[0111] In some embodiments of this application, the transfer device 2 is provided with a first limiting component 7 and a second limiting component 8. The transfer device 2 in the first position abuts against the housing 1 via the first limiting component 7, causing the transfer device 2 to stop in the first position. The transfer device 2 in the second position abuts against the housing 1 via the second limiting component 8, causing the transfer device 2 to stop in the second position. By providing the first limiting component 7 and the second limiting component 8, overtravel of the transfer device 2 can be prevented, ensuring that the transfer device 2 accurately stops in the first or second position.

[0112] Specifically, see Figure 3 , Figure 7 and Figure 8Both the first limiting component 7 and the second limiting component 8 include a first mounting plate 71, a buffer 72, and a rigid stop 73. The first mounting plate 71 is fixedly connected to the transfer device 2, providing a mounting base for the buffer 72 and the rigid stop 73. The buffer 72 includes a fixed housing 721 and a buffer head 722. The fixed housing 721 is connected to the first mounting plate 71, and the buffer head 722 is elastically and telescopically disposed on the fixed housing 721, and the buffer head 722 elastically abuts against the housing 1. When the transfer device 2 is about to reach the first position or the second position, the buffer head 722 of the buffer 72 first contacts the inside of the housing 1, so that the buffer head 722 moves into the fixed housing 721 until the transfer device 2 stops at the first position or the second position, thereby playing a role in buffering, vibration absorption, and noise reduction. The rigid stop 73 is connected to the first mounting plate 71 and can rigidly abut against the housing 1. The rigid stop 73 only comes into rigid contact with the inside of the housing 1 after the buffer 72 comes into contact with the inside of the housing 1, preventing large collision noise. Due to the rigid contact, it can ensure that the transfer device 2 is stably stopped in the first or second position, effectively avoiding the phenomenon of overtravel.

[0113] For example, buffer 72 is a hydraulic buffer.

[0114] For example, the first mounting plate 71 is an L-shaped plate structure, with its first end fixedly connected to the transfer device 2, and its second end used to mount the buffer 72 and the rigid stop 73. The rigid stop 73 is a bolt that passes through the first mounting plate 71 and is locked in place by a nut.

[0115] More specifically, see Figure 3 and Figure 6 A limiting hole 53 is provided on the supporting base 5. A first limiting component 7 is connected to the bottom of the transfer device 2 and is movably inserted into the limiting hole 53. The first limiting component 7 can abut against the inner wall of the limiting hole 53, so that the transfer device 2 stops in a first position. Figure 7 and Figure 8 A stop plate 54 is connected above the support base 5, and the second limiting component 8 is located above the support base 5 and can abut against the stop plate 54 to stop the transfer device 2 in the second position. By providing limiting holes 53 and stop plates 54 on the support base 5, abutment surfaces can be provided for the first limiting component 7 and the second limiting component 8 respectively, ensuring that the transfer device 2 can accurately stop in the first and second positions, while making the structural layout more reasonable and compact.

[0116] For example, two first limiting components 7 arranged along the Y direction are provided at one end of the transfer device 2, and two second limiting components 8 arranged along the Y direction are provided at the other end of the transfer device 2 to ensure the reliability of stopping the transfer device 2. In other embodiments, the number of first limiting components 7 and second limiting components 8 can be one or more, and is not limited.

[0117] like Figure 3 , Figure 5 as well as Figure 9 As shown, the transfer device 2 is provided with a first positioning hole 211 and a second positioning hole 212. The transfer machine 1000 also includes a positioning mechanism 9, which includes a positioning housing 91 and a positioning end 92. The positioning housing 91 is connected to the housing 1, and the positioning end 92 is retractably disposed in the positioning housing 91. When the transfer device 2 moves to the first position, the positioning end 92 can be inserted and engaged with the first positioning hole 211 to make the entire transfer device 2 stably positioned in the first position and not move. When the transfer device 2 needs to move to the second position, the positioning end 92 moves relative to the positioning housing 91 to disengage from the first positioning hole 211. When the transfer device 2 moves to the second position, the positioning end 92 can be inserted into the second positioning hole 212 to make the transfer device 2 stably positioned in the second position and not move, so as to clear the maintenance passage for maintenance personnel. When the maintenance work is completed, the transfer device 2 needs to be moved to the first position to perform transfer work between the two transfer machines 1000 again. At this time, the positioning end 92 moves relative to the positioning housing 91 to disengage from the second positioning hole 212, and when the transfer device 2 stops in the first position, it is reinserted into the first positioning hole 211.

[0118] For example, the positioning mechanism 9 is a cylinder or a hydraulic cylinder. Taking a cylinder as an example, the positioning housing 91 is the cylinder body of the cylinder, and the positioning end 92 is the end of the telescopic rod of the cylinder or a positioning block installed at the end of the telescopic rod.

[0119] Further, see Figure 5 The positioning mechanism 9 is mounted on the bearing base 5 via the positioning mounting plate 93. The positioning mechanism 9 is arranged vertically so that its driving direction is the Z direction.

[0120] See Figure 5 and Figure 6 The support base 5 is provided with a second through hole 52. The positioning mechanism 9 is installed on the bottom of the support base 5 through the positioning mounting plate 93. Its positioning end 92 passes through the second through hole 52 and is inserted into the first positioning hole 211 or the second positioning hole 212.

[0121] The second through-hole 52 is connected to the first through-hole 51, making processing more convenient. For example, the second through-hole 52 extends along the Y direction and is connected to the first through-hole 51 to form a T-shaped hole structure. There are two positioning mechanisms 9. Correspondingly, there are also two first positioning holes 211 and two second positioning holes 212, which correspond one-to-one with the two positioning mechanisms 9. The positioning ends 92 of the two positioning mechanisms 9 pass through the two ends of the second through-hole 52 respectively and are inserted into the corresponding first positioning hole 211 or second positioning hole 212.

[0122] In this embodiment, see Figure 2 The transfer machine 1000 also includes a control unit (not shown) and an operation button 10. The operation button 10 is located on the outer wall of the housing 1 and is communicatively connected to the control unit. The control unit is also communicatively connected to the first drive mechanism 3. The operation button 10 is used to receive user operation commands. Upon receiving the operation command, the control unit controls the first drive mechanism 3 to start, so that the first drive mechanism 3 drives the transfer device 2 to switch between a first position and a second position. During maintenance work, maintenance personnel only need to operate the operation button 10 to automatically retract the transfer device 2 into the housing 1 and stop it in the second position, thereby clearing a maintenance passage between the two transfer machines 1000.

[0123] For example, the operation button 10 can be a button or a knob that can be pressed and turned by the operator to send operation commands. Alternatively, the operation button 10 can also be a selection button on a touch screen.

[0124] like Figure 4 , Figure 7 as well as Figure 8 As shown, the transfer device 2 includes a carrier unit 21, a transfer unit 22, and a docking channel unit 23. The carrier unit 21 is movably mounted on a support base 5 inside the housing 1. Specifically, the carrier unit 21 is provided with the aforementioned first positioning hole 211, second positioning hole 212, and slider 62. The first limiting component 7 and the second limiting component 8 are mounted on the carrier unit 21 and are respectively located on the upper and lower sides of the carrier unit 21. The transfer unit 22 is mounted on the carrier unit 21 and is used to transfer material 2000. The docking channel unit 23 is mounted on the carrier unit 21 and is used to convey material 2000. The docking channel units 23 of the two transfer machines 1000 can extend at least partially out of the through opening 11 and dock separately under the drive of the corresponding carrier unit 21. That is, when the transfer devices 2 of the two transfer machines 1000 move to the first position, their docking channel units 23 dock to convey material 2000. For example, material 2000 on one docking flow channel unit 23 is transferred to another docking flow channel unit 23. Transfer unit 22 is used to transfer material 2000 to docking flow channel unit 23 or to transfer material 2000 on docking flow channel unit 23 out.

[0125] In this embodiment, the transfer device 2 further includes a protective cover 24, which is connected to the carrier unit 21 and movably passes through the through opening 11. Figure 2 The protective cover 24 is provided with a first window 2421, through which the docking flow channel unit 23 extends at least partially to dock with the docking flow channel unit 23 of another transfer machine 1000. When the transfer device 2 is in the first position, the protective cover 24 extends at least partially beyond the through opening 11 to cover the docking flow channel unit 23 and / or the transfer unit 22. By providing the protective cover 24, effective protection can be provided for the part of the transfer device 2 extending outside the through opening 11 in the first position, preventing personnel or equipment from accidentally touching the transfer device 2. At the same time, the first window 2421 of the protective cover 24 facilitates the extension of the docking flow channel unit 23 to achieve docking with another transfer machine 1000.

[0126] Understandably, the transfer devices 2 of the two transfer machines 1000 are provided with protective covers 24 at the ends facing each other.

[0127] Specifically, see Figure 7 , Figure 9 as well as Figure 10 The protective cover 24 includes a surrounding plate 241 and a baffle 242. The baffle 242 is positioned directly opposite the through opening 11, meaning the normal to the plane containing the baffle 242 is parallel to the axis of the through opening 11. The surrounding plate 241 surrounds the circumference of the baffle 242, and a first window 2421 is opened on the baffle 242. The baffle 242 and / or the surrounding plate 241 are connected to the carrier unit 21. The surrounding plate 241 and the baffle 242 together create a protective space for covering one end of the transfer device 2, making manufacturing and installation relatively convenient.

[0128] See Figure 2 The enclosure 241 is also provided with a second window 2411, which is connected to the first window 2421. Through the second window 2411, part of the docking flow channel unit 23 can be exposed so that personnel can observe the material 2000 conveying status.

[0129] See Figure 7 , Figure 9 as well as Figure 10The side of the enclosure 241 is provided with a flange, which is installed on the carrier unit 21 by an L-shaped mounting bracket 27 and fasteners such as screws and bolts. The bottom of both the enclosure 241 and the baffle 242 are provided with flanges, which are fixed to the carrier unit 21 by fasteners such as screws and bolts. An extension plate 2422 extends inward from one side of the first window 2421. The end of the extension plate 2422 away from the first window 2421 is provided with a flange, which is installed on the carrier unit 21 by an L-shaped mounting bracket 27 and fasteners such as screws and bolts, ensuring that the protective cover 24 is stably and reliably fixedly connected to the carrier unit 21, thereby providing effective protection for the part of the transfer device 2 that extends out of the through opening 11.

[0130] See Figure 7 and Figure 8 The transfer unit 22 of the transfer device 2 provided in this embodiment includes a support frame 221, a second drive mechanism 222, a third drive mechanism 223, a first clamping mechanism 224, a fourth drive mechanism 225, a fifth drive mechanism 226, and a second clamping mechanism 227. In the figure, the X direction is defined as the first direction, the Z direction as the second direction, and the Y direction as the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0131] The support frame 221 is connected to the carrier unit 21, and the second drive mechanism 222 and the fourth drive mechanism 225 are respectively located on both sides of the support frame 221 along the third direction.

[0132] The third drive mechanism 223 is connected to the output end of the second drive mechanism 222, and the first clamping mechanism 224 is connected to the output end of the third drive mechanism 223. The second drive mechanism 222 is used to drive the third drive mechanism 223 to move along the first direction, and the third drive mechanism 223 is used to drive the first clamping mechanism 224 to move along the second direction. The first clamping mechanism 224 is used to clamp the material 2000, and under the drive of the second drive mechanism 222 and the third drive mechanism 223, it can move along the first direction and the second direction to transfer the material 2000 to the designated position and release it.

[0133] The fifth drive mechanism 226 is connected to the output end of the fourth drive mechanism 225, and the second clamping mechanism 227 is connected to the output end of the fifth drive mechanism 226. The fourth drive mechanism 225 is used to drive the fifth drive mechanism 226 to move in the first direction, and the fifth drive mechanism 226 is used to drive the second clamping mechanism 227 to move in the second direction. The second clamping mechanism 227 is used to clamp the material 2000, and under the drive of the fourth drive mechanism 225 and the fifth drive mechanism 226, it can move in the first direction and the second direction to transfer the material 2000 to the designated position and release it.

[0134] By distributing the second drive mechanism 222 and the fourth drive mechanism 225 on both sides of the support frame 221 along the Y direction, the material 2000 can be clamped and transferred on both sides of the support frame 221, thus enriching the transfer function.

[0135] For example, the second drive mechanism 222 and the fourth drive mechanism 225 are both linear modules, the third drive mechanism 223 and the fifth drive mechanism 226 are both cylinders or hydraulic cylinders, and the first clamping mechanism 224 and the second clamping mechanism 227 are both gripper cylinders.

[0136] Continue reading Figure 7 and Figure 8 The transfer device 2 further includes a first flow channel unit 25 and a second flow channel unit 26. The first flow channel unit 25, the second flow channel unit 26, and the docking flow channel unit 23 are arranged sequentially at intervals along a first direction (X direction). The first flow channel unit 25 and the second flow channel unit 26 both convey material 2000 along a third direction (Y direction), and the docking flow channel unit 23 conveys material 2000 along the first direction (X direction). The first clamping mechanism 224 is used to transfer material 2000 between the first flow channel unit 25 and the second flow channel unit 26 under the drive of the second drive mechanism 222 and the third drive mechanism 223. The second clamping mechanism 227 is used to transfer material 2000 between the first flow channel unit 25, the second flow channel unit 26, and the docking flow channel unit 23 under the drive of the fourth drive mechanism 225 and the fifth drive mechanism 226.

[0137] For example, in Figure 1 In the transfer machine 1000 on the left side, material 2000 entering the first end of the first flow channel unit 25 can be clamped and transferred by the first clamping mechanism 224 to the first end of the second flow channel unit 26, and then conveyed to the second end on the second flow channel unit 26, thus entering the next station; or, material 2000 entering the first end of the first flow channel unit 25 can be conveyed to the second end of the first flow channel unit 25, thus entering the next station. The second ends of the first flow channel unit 25 and the second ends of the second flow channel unit 26 are directly opposite the docking flow channel unit 23.

[0138] exist Figure 1In the right-hand transfer machine 1000, the material 2000 entering the first end of the first flow channel unit 25 moves in the same manner as the left-hand transfer machine 1000. Furthermore, the material 2000 conveyed to the second end by the first flow channel unit 25 and the material 2000 conveyed to the second end by the second flow channel unit 26 can be transferred to the docking flow channel unit 23 in the right-hand transfer machine 1000 under the drive of the second clamping mechanism 227. The conveying direction of the docking flow channel units 23 of the two transfer machines 1000 is the same, for example, both convey to the left. After the two docking flow channel units 23 dock, the material 2000 on the right docking flow channel unit 23 can be conveyed to the left docking flow channel unit 23. The material 2000 on the left docking flow channel unit 23 can then be clamped and transferred by the second clamping mechanism 227 to the second end of the second flow channel unit 26, and further flow to the next station.

[0139] like Figure 11 As shown, the docking flow channel unit 23 includes a first fixed frame 231, a first motor 232, a first belt drive mechanism 233, a first position detection mechanism 234, and a first blocking mechanism 235. The first fixed frame 231 is fixedly mounted on the carrier unit 21. Two sets of first belt drive mechanisms 233 are arranged along the Y direction and are connected in a transmission manner. The first motor 232 and the first belt drive mechanisms 233 are both mounted on the first fixed frame 231, and the first motor 232 is connected in a transmission manner to the drive wheel of one of the first belt drive mechanisms 233 to drive the two first belt drive mechanisms 233 to convey materials 2000 placed on the conveyor belt of the first belt drive mechanism 233 along the X direction. The first position detection mechanism 234 is located on the first fixed frame 231 and is used to detect whether there is material 2000 at the current position. The first blocking mechanism 235 is used to rise when the first position detection mechanism 234 detects the presence of material 2000 to block the material 2000 from continuing to move forward, facilitating the positioning of individual materials 2000.

[0140] For example, the first position detection mechanism 234 includes two through-beam fiber optic sensors, one of which is a transmitter and the other is a receiver. When the fiber optic cable emitted by the transmitter cannot be received by the receiver, it indicates that the fiber optic cable is blocked by material 2000, and material 2000 is detected at the position. The first blocking mechanism 235 includes a cylinder and a stop. The cylinder is mounted on the first fixed frame 231 and drives the stop to rise or fall to block or avoid material 2000.

[0141] The structures of the first flow channel unit 25 and the second flow channel unit 26 are similar. Taking the first flow channel unit 25 as an example, as follows: Figure 12As shown, the first flow channel unit 25 includes a second fixing frame 251, a second motor 252, a second belt drive mechanism 253, a second position detection mechanism 254, and a second blocking mechanism 255. The second fixing frame 251 is fixedly mounted on the carrier unit 21.

[0142] Two sets of second belt drive mechanisms 253 are arranged along the X direction and are connected in a transmission manner. The second motor 252 and the second belt drive mechanism 253 are both mounted on the second fixed frame 251. The second motor 252 is connected in a transmission manner to the drive wheel of one of the second belt drive mechanisms 253 to drive the two second belt drive mechanisms 253 to move along the Y direction, thereby conveying the material 2000 placed on the conveyor belt of the second belt drive mechanism 253. A second position detection mechanism 254 is located on the second fixed frame 251 and is used to detect whether material 2000 is present at the current position. A second blocking mechanism 255 is used to rise when the second position detection mechanism 254 detects the presence of material 2000 to block the material 2000 from continuing to move forward, facilitating the positioning of individual material 2000.

[0143] For example, the second position detection mechanism 254 includes two through-beam fiber optic sensors, one of which is a transmitter and the other is a receiver. When the fiber optic cable emitted by the transmitter cannot be received by the receiver, it indicates that the fiber optic cable is blocked by material 2000, and material 2000 is detected at the detection location. The second blocking mechanism 255 includes a cylinder and a stop. The cylinder is mounted on the second fixed frame 251 and drives the stop to rise or fall to block or avoid material 2000.

[0144] Further, see Figure 2 The box body 1 has a first conveying port 120 through both sides along the Y direction. The first conveying port 120 is directly opposite the first flow channel unit 25 and the second flow channel unit 26, so as to receive material 2000 or allow material 2000 to enter the next station through the first conveying port 120.

[0145] like Figure 13 and Figure 14 As shown, a conveying device 20 is also provided inside the housing 1 for conveying material 2000 along the Y direction. It is located below the transfer device 2 to make full use of the internal space of the transfer machine 1000 to transport material 2000.

[0146] See Figure 2 , Figure 4 and Figure 14The support base 5 is located in the middle of the housing 1, dividing the internal space of the housing 1 into an upper space and a lower space. The upper space is the first chamber 12, which is used to install the transfer device 2. The lower space is provided with a partition plate 15, which extends vertically to divide the lower space into a second chamber 13 and a third chamber 14. The second chamber 13 is provided with a power socket 30 and other electrical components, and the third chamber 14 is provided with the aforementioned transfer device 20.

[0147] like Figure 13 As shown, the conveying device 20 includes a third fixed frame and a third motor and a third belt drive mechanism mounted on the third fixed frame. The third fixed frame is located on the bottom wall of the third chamber 14. The third motor and the third belt drive mechanism are connected for transmission, used to convey the material 2000 along the Y direction. Further, combined with... Figure 14 The box body 1 has a second conveying port 130 through both sides along the Y direction. The second conveying port 130 specifically penetrates the side wall of the third chamber 14. The second conveying port 130 is directly opposite the conveying device 20 so as to receive material 2000 or allow material 2000 to enter the next station through the second conveying port 130.

[0148] See Figure 2 and Figure 14 The housing 1 is equipped with a first door 16, a second door 17, and a third door 18. The first door 16 is used to open or close the first chamber 12, the second door 17 is used to open or close the second chamber 13, and the third door 18 is used to open or close the third chamber 14, so as to facilitate maintenance and inspection of the devices or components inside the three chambers.

[0149] See Figure 14 The outer wall of the housing 1 is also provided with a first operation panel 19 and a second operation panel 110. The operator can operate the equipment through the first operation panel 19 and the second operation panel 110 to achieve human-machine interaction. For example, the first operation panel 19 is provided with buttons for start, stop, reset, lighting, and emergency stop, and the second operation panel 110 is provided with a power button, a gas source button, a pressure gauge, and a debugging interface, etc. The specific arrangement can be determined according to design requirements and is not limited to the buttons or instruments listed.

[0150] This embodiment also provides a control method for a transfer system, applied to the transfer system described above, the control method for the transfer system including:

[0151] S1. Receive operation instructions, including work instructions and maintenance instructions;

[0152] S2. When the received operation command is a work command, control the transfer device 2 to move from the second position to the first position;

[0153] When the received operation command is a maintenance command, the control transfer device 2 is moved from the first position to the second position.

[0154] The aforementioned work instructions are for docking the transfer devices 2 of the two transfer machines 1000, while the maintenance instructions are for separating the transfer devices 2 of the two transfer machines 1000 to create a maintenance passage for maintenance personnel. Specifically, the operator can issue an operation instruction via the operation button 10, which is then received by the control unit. If it is a maintenance instruction, the control unit controls the first drive mechanism 3 to move the transfer device 2 from the first position to the second position, facilitating passage for maintenance personnel. This allows maintenance personnel to pass through the passage between the two transfer machines 1000 without climbing a ladder, reducing the difficulty of maintenance work, improving maintenance efficiency, and reducing safety risks during maintenance operations.

[0155] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
