The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] Reference Figure 1 、 Figure 2The carrier 100 of the present invention has a frame 120 for carrying materials 110. The frame 120 can be carried by a carrying device 200 and docked with a first device 300 for processing the materials 110, so that the materials 110 can be transferred between the carrier 100 and the first device 300. The frame 120 is provided with: a conveying portion 130, a docking portion 140 and a blocking device 400, wherein the conveying portion 130 is used to convey the materials 110; the docking portion 140 is connected to at least one end of the conveying portion 130, and when the carrier 100 and the first device 300 are docked, it is connected to the power system 310 of the first device 300 and drives the conveying portion 130 to convey the materials 110; the blocking device 400 is provided in the direction of conveyance of the conveying portion 130 ( Figure 1 、 Figure 2 In the front and rear directions, the carrier 100 can block the material 110. When the carrier 100 and the first device 300 are docked, the carrier 100 is driven by the first device 300 to release the obstruction to the material 110.

[0041] In this embodiment, since the conveying part 130 for conveying the material 110 and the blocking device 400 for blocking the material 110 on the carrier 100 are driven by the first device 300 docked with the carrier 100, there is no need to set up an independent drive system on the carrier 100, which can reduce the cost of the carrier 100. In addition, since one set of power system 310 of the first device 300 can correspond to multiple sets of carriers 100 without independent drive systems, the cost of the production line can be greatly reduced.

[0042] It is conceivable that the material 110 should be understood in a broad sense. Materials 110 can include, for example, workpieces and products that need to be processed. These workpieces and products can be placed directly on the rack 120 or loaded using fixtures, jigs, pallets, etc., and then placed on the rack 120. In addition, processing should also be understood in a broad sense and can refer to any process in the production process of a workpiece or product, such as machining, welding, component assembly, coating, testing, etc.; it can also refer to auxiliary processes in the production process of a workpiece or product, such as downtime, manual intervention, and waste disposal. The first device 300 is any device that performs these processes or auxiliary processes. In addition, the device should also be interpreted in a broad sense. As long as it has an independent power system, there is no special limitation. For example, it can be an independent device fixed to the ground, an independent device with an assembly line, an assembly line, an elevator, etc.

[0043] It can be imagined that the rack 120 can be any form of rack 120 as long as it can carry the material 110 and be transported by the transport device 200. From the material point of view, for example, there can be listed: a rack using profile welding, a rack built with aluminum profiles, or a rack combining profile welding and aluminum profiles, etc.; from the structural point of view, for example, there can be listed: a rack with supporting feet, a rack with universal casters, or a rack with feet and universal casters, etc.; from the storage space point of view, for example, there can be listed: a single-layer rack that can carry materials 110, a rack with multiple layers up and down that can carry materials 110, a rack with multiple layers in the left and right directions and multiple layers in the upper and lower directions that can carry materials 110, etc.

[0044] It is conceivable that the form of the transport device 200 is not particularly limited as long as it can transport the carrier 100, and examples thereof include: an AGV vehicle (e.g. Figure 1 、 Figure 2 The transport device 200) is a transport robot mounted on a walking track, such as a three-axis manipulator, a six-axis robot, and other transport robots, and various conveyor lines with independent power such as roller lines and plate chain conveyor lines. In addition, in the case of manual operation, the operator can also be understood as a special transport device.

[0045] It can be understood that, according to the docking of the carrier 100 and the first device 300, the docking covers the entire process of the carrier 100 and the first device 300 from the moment of docking to the completion of docking, and the process includes: the trend of starting docking, docking, when docking is completed, and any stage of being in a stable docking state after docking is completed.

[0046] It can be imagined that driving the conveying part 130 to convey the material 110 should include various conveying situations, for example, the situation of conveying the material 110 from the carrier 100 to the first device 300, and the situation of conveying the material from the first device 300 to the carrier 100, etc.

[0047] Reference Figure 3 And continue to refer to Figure 1 、 Figure 2In some embodiments, in order to smoothly and continuously convey the material 110, the conveying unit 130 includes a logistics line 131, one end of which is provided with a first transmission shaft 132, and the connecting unit 140 is connected to the first transmission shaft 132. Specifically, the material 110 can be placed on the logistics line 131. After the carrier 100 and the first device 300 are docked, the logistics line 131 is connected to the power system 310 provided on the first device 300 through the connecting unit 140, and is thereby driven by the power system 310 on the first device 300. While carrying the material 110, the logistics line 131 is conveyed to the first device 300. The logistics line 131 can be selected from, for example, a belt line, a roller line, a roller chain line, a double-speed chain line, a plate chain line, etc. As a result, the conveying unit 130 can carry the material 110 and, after being driven, can also directly convey the material 110 to the first device 300.

[0048] It can be imagined that the first transmission shaft 132 can be a support shaft that directly supports and transmits pulleys, synchronous pulleys, rollers, sprockets, etc., or it can be a transmission shaft connected to these support shafts through belt transmission mechanisms, chain transmission mechanisms, gear transmission mechanisms, belt transmission mechanisms, couplings, etc.

[0049] In some embodiments, in order to achieve a smooth connection between the power system 310 of the first device 300 and the docking portion 140, the docking portion 140 may include a first engaging member 142, and the first engaging member 142 is connected to the first transmission shaft 132. Specifically, for example, the first engaging member 142 and the first transmission shaft 132 are coaxially connected. Correspondingly, the motor 311 of the power system 310 of the first device 300 is connected to a second engaging member 312 that can engage with the first engaging member 142, and drives the second engaging member 312 to rotate. The first engaging member 142 and the second engaging member 312 are not particularly limited as long as they can engage. The first engaging member 142 can be, for example, an inner hexagonal socket, a claw, etc., and correspondingly, the second engaging member 312 can be, for example, an outer hexagonal shaft that adapts to the inner hexagonal socket, a claw that adapts to the claw, etc. In order to engage or disengage the second engaging member 312 with the first engaging member 142, thereby achieving docking or disconnection between the power system 310 and the docking portion 140, the power system 310 further includes a driving element 313, such as a driving cylinder, that drives the motor 311 to switch positions. The driving element 313 drives the second engaging member 312 to approach the first engaging member 142 along the axial direction (left-right direction in the figure) of the first engaging member 142. In this way, a smooth docking between the power system 310 of the first device 300 and the docking portion 140 can be achieved. After the transport device 200 transports the carrier 100 and docks it with the first equipment 300, the driving element 313 of the power system 310 drives the motor 311 to switch position, for example, the driving motor 311 extends, and the second engaging member 312 engages with the first engaging member 142. Thus, when the motor drives the second engaging member 312 to rotate, it can drive the first engaging member 142 and the first transmission shaft 132 to rotate, thereby driving the logistics line 131 of the conveying part 130 to rotate.

[0050] It is conceivable that the motor 311 can be connected to the second engaging member 312 via a transmission mechanism 314 such as a belt transmission mechanism, a chain transmission mechanism, a gear transmission mechanism, a belt transmission mechanism, a coupling, etc.

[0051] Reference Figure 4 、 Figure 5In some embodiments, in order to achieve smooth docking between the power system 310 of the first device 300 and the docking portion 140, the docking portion 140 includes a first gear 141, and the first gear 141 is connected to the first transmission shaft 132. Specifically, the power system 310 of the first device 300 can be, for example, a power system 310 driven by a motor 311. The motor 311 of the power system 310 is connected to a second gear 315 that can mesh with the first gear 141 and drives the second gear 315 to rotate. In order to engage or disengage the second gear 315 with the first gear 141 to achieve docking or disengagement between the power system 310 and the docking portion 140, the power system 310 further includes a driving element 313, such as a driving cylinder, that drives the motor 311 to switch positions. The driving element 313 drives the second gear 315 to approach the first gear 141 along the radial direction of the first gear 141 (the up and down direction in the figure). After the transport device 200 transports the carrier 100 and docks it with the first equipment 300, the driving element 313 of the power system 310 drives the motor 311 to switch position, for example, the driving motor 311 extends, and the second gear 315 and the first gear 141 engage. Therefore, when the motor 311 drives the second gear 315 to rotate, it can drive the first gear 141 and the first transmission shaft 132 to rotate, thereby driving the logistics line 131 of the conveying part 130 to rotate.

[0052] Because the conveyor 130 lacks an independent drive system, the rotation of the conveyor 130 can cause the material 110 to move while the transport device 200 is transporting the carrier 100. Furthermore, due to inertia during transport, the material 110 can slip and fall off the conveyor 130. In the present invention, the blocking device 400 prevents the material 110 from falling off the carrier 100 during transport.

[0053] The following reference Figures 6 to 13 , the blocking device 400 is described in more detail.

[0054] Reference Figure 6 、 Figure 7 、 Figure 8 In some embodiments, the blocking device 400 includes: a blocking member 420, a first driving member 430, a first connecting member 440 and a first elastic member 450. The blocking member 420 is swingably mounted to the frame 120. The blocking member 420 can be driven by the first device 300, for example, by the protruding block 321 of the first device 300, and is moved from the blocking position 401 (refer to Figure 9 、 Figure 10 ), switches to the release position 402 for releasing the obstruction of the material 110 (refer to Figure 12The first driving member 430 is swingably mounted to the frame 120. The first connecting member 440 is connected to the blocking member 420 and the first driving member 430, respectively. The first connecting member 440 is connected to the blocking member 420 at a first connecting position 403 (see FIG. Figure 10 ), and the second connection position 404 (refer to Figure 11 ), at least one of which can be changed. When the carrier 100 and the first device 300 are docked, the first driving member 430 is driven by the first device 300 to swing, and by pulling the first connecting member 440, the blocking member 420 is driven to swing, switching from the blocking position 401 to the release position 402. The first elastic member 450 is configured to drive the blocking member 420 to the blocking position 401.

[0055] Since the first connecting member 440 is respectively connected to the blocking member 420 and the first driving member 430, when the first driving member 430 is driven, the first connecting member 440 drives the blocking member 420 to switch between the blocking position 401 and the release position 402. In addition, since the first elastic member 450 is provided to drive the first driving member 430 so that the blocking member 420 is in the blocking position 401, even if the carrier 100 does not have a driving system, it can still block the material 110 carried by the carrier 100.

[0056] It is conceivable that, referring to Figure 9 、 Figure 10 , the blocking position 401 refers to the position where the blocking member 420 limits the passage of the material 110, for example; Figure 12 The release position 402 refers to a position where the blocking member 420 allows the blocked material 110 to pass through.

[0057] In some embodiments, in order to facilitate the assembly and disassembly of the blocking device 400, the blocking device 400 may further include a mounting base 410. The mounting base 410 may be a single component that is integrally formed, or a component that is assembled from multiple sub-parts. The blocking device 400 may mount the blocking member 420, the first driving member 430, the first connecting member 440, and the first elastic member 450 to the frame 120 via the mounting base 410. Specifically, the blocking member 420 may be swingably mounted to the mounting base 410, and the first end portion 421 of the blocking member 420 may extend out of the mounting base 410 and may be moved to the blocking position 401 (refer to FIG. 1 ) as the blocking member 420 swings. Figure 9 、 Figure 10 ) and release position 402 (refer to Figure 12 ) switches between; the first drive member 430 is swingably mounted to the mounting base 410, and the second end portion 431 of the first drive member 430 extends out of the mounting base 410.

[0058] It can be imagined that, in the above description, although the first end 421 of the blocking member 420 is described as extending out of the mounting base 410, those skilled in the art should broadly understand that: the first end 421 extending out of the mounting base 410 is not limited to the first end 421 having to extend as a whole out of the mounting base 410, but means that as long as the first end 421 extends to a position where the mounting base 410 does not interfere with the material 110, it will suffice. For example, when the mounting base 410 is in the shape of a U-shaped groove, and the material 110 passes through the U-shaped groove of the mounting base 410, the first end 421 extends into the U-shaped groove, which means that the first end 421 extends out of the mounting base 410.

[0059] In addition, similarly, although it is described that the second end 431 of the first driving member 430 extends out of the mounting base 410, technical personnel in this field should broadly understand that: the second end 431 extending out of the mounting base 410 is not limited to the second end 431 having to extend as a whole out of the mounting base 410, but means that as long as the second end 431 extends to a position where the mounting base 410 does not interfere with, for example, a docking device, for example, when the mounting base 410 is in the shape of a U-shaped groove and the docking device partially extends into the U-shaped groove of the mounting base 410, as long as the second end 431 extends into the U-shaped groove, it means that the second end 431 extends out of the mounting base 410.

[0060] Reference Figure 8 、 Figure 10In some embodiments, the first connecting member 440 and the blocking member 420 are slidably connected to each other, allowing the first connection position 403 to be changed. Specifically, for example, the mounting base 410 is provided with a first mounting plate 412, on which a first rotating member 413, such as a rotating pin, is mounted. The first rotating member 413 extends in the front-to-back direction. Correspondingly, the first intermediate portion 423 of the blocking member 420 is provided with a first rotating hole 424. The first rotating hole 424 is adapted to fit within the first rotating member 413 and rotates about the first rotating member 413. The first end portion 421 is provided at the upper portion of the blocking member 420, connected to the upper end of the first intermediate portion 423, and extends outward at an acute angle R1, such as approximately 60°, relative to the upper end of the first intermediate portion 423. The third end portion 425 is provided at the lower portion of the blocking member 420, connected to the lower end of the first intermediate portion 423, and extends outward at an acute angle R2, such as approximately 60°, relative to the lower end of the first intermediate portion 423. The upper portion of the first connecting member 440 is slidably connected to the third end 425. As the first driving member 430 drives the first connecting member 440, the third end 425 of the blocking member 420 slides relative to the first connecting member 440, while the blocking member 420 rotates about the first rotating member 413, causing the first end 421 of the blocking member 420 to swing vertically. When the first end 421 swings downward, it is in a blocking position 401, which can restrict, for example, the material 110 and prevent it from falling. When the first end 421 swings upward, it is in a release position 402, which allows, for example, the material 110 to be transferred. By providing a slidable connection between the first connecting member 440 and the blocking member 420, allowing the first connection position 403 to change, the first connecting member 440 and the blocking member 420 can be prevented from getting stuck, thereby allowing the blocking member 420 to swing smoothly.

[0061] In some embodiments, one of the first connecting member 440 and the blocking member 420 is provided with a first guide portion 422, and the other is provided with a first sliding member 441. The first sliding member 441 is adapted to the first guide portion 422 and slides along the first guide portion 422. As a result, the first connecting member 440 and the blocking member 420 can be smoothly slidably connected to each other. For example, a groove can be provided at the third end 425 of the blocking member 420 as the first guide portion 422, and a sliding pin can be provided on the first connecting member 440 as the first sliding member 441. The first sliding member 441 is inserted into the first guide portion 422 in the front-to-back direction and slides along the first guide portion 422. As a result, when the first connecting member 440 is driven, for example, in the up-down direction, the first sliding member 441 simultaneously pulls the blocking member 420 in the up-down direction, thereby causing the blocking member 420 to swing.

[0062] It can be imagined that although the above description is based on setting the first guide part 422 to the blocking member 420 and setting the first sliding member 441 to the first connecting member 440, it is not limited to this. The first guide part 422 can also be set to the first connecting member 440, and the first sliding member 441 can also be set to the blocking member 420.

[0063] Reference Figure 11 、 Figure 13 In some embodiments, the first connecting member 440 and the first driving member 430 are slidably connected to each other so that the second connection position 404 can be changed. Specifically, for example, the mounting base 410 is provided with a second mounting plate 414, which is substantially perpendicular to the first mounting plate 412. A second rotating member 415, such as a rotating pin, is mounted on the second mounting plate 414. The second rotating member 415 extends in the left-right direction, that is, the second rotating member 415 is substantially perpendicular to the first rotating member 413. Correspondingly, the second intermediate portion 433 of the first driving member 430 is provided with a second rotating hole 434. The second rotating hole 434 and the second rotating member 415 are adapted to rotate around the second rotating member 415. The second end portion 431 is provided at the lower portion of the first driving member 430 and is connected to the lower end of the second intermediate portion 433. The second end portion 431 extends outward at an acute angle R3, such as 60°, relative to the lower end of the second intermediate portion 433. A fourth end portion 435 is provided at the upper portion of the first driving member 430. The fourth end portion 435 is connected to the upper end of the second intermediate portion 433 and extends outward at a substantially acute angle R4, for example, 60°, relative to the upper end of the second intermediate portion 433. The lower portion of the first connecting member 440 is slidably connected to the fourth end portion 435, thereby pulling the first connecting member 440 as the first driving member 430 swings.

[0064] In some embodiments, one of the first connecting member 440 and the first driving member 430 is provided with a second guide portion 432, and the other is provided with a second sliding member 442. The second sliding member 442 is adapted to the second guide portion 432 and slides along the second guide portion 432. In this way, the first connecting member 440 and the first driving member 430 can be smoothly slidably connected to each other. For example, a groove portion can be provided at the fourth end portion 435 of the first driving member 430 as the second guide portion 432, and a sliding pin can be provided at the first connecting member 440 as the second sliding member 442. The second sliding member 442 is moved in the left-right direction (in the right direction). Figure 11 、 Figure 13 The fourth end portion 435 is inserted into the second guide portion 432 (in the direction perpendicular to the paper) and slides along the second guide portion 432. Therefore, when the first driving member 430 is driven in the front-back direction, the first driving member 430 rotates around the second rotating member 415, and the fourth end portion 435 swings and pulls the first connecting member 440, thereby causing the blocking member 420 to swing.

[0065] It can be imagined that although the above description is based on setting the second guide part 432 to the first driving member 430 and setting the second sliding member 442 to the first connecting member 440, it is not limited to this. The second guide part 432 can also be set to the first connecting member 440, and the second sliding member 442 can also be set to the first driving member 430.

[0066] It is conceivable that although the above description uses the example that the first connecting member 440 is slidably connected to the blocking member 420 and the first driving member 430 respectively, so as to change the first connection position 403 where the first connecting member 440 connects to the blocking member 420 and the second connection position 404 where the first connecting member 440 connects to the first driving member 430, thereby realizing the mutual linkage of the first driving member 430, the blocking member 420, and the first connecting member 440, the present invention is not limited to this. For example, the first connecting member 440 may also be only slidably connected to the blocking member 420 (i.e., the first connection position 403 is changeable), and the first connecting member 440 is hinged to the first driving member 430 via a connecting rod (not shown), thereby realizing the mutual linkage of the first driving member 430, the blocking member 420, and the first connecting member 440. Alternatively, the first connecting member 440 may be only slidably connected to the first driving member 430 (i.e., the second connection position 404 is changeable), and the first connecting member 440 is hingedly connected to the blocking member 420 via a connecting rod (not shown), thereby realizing the mutual linkage of the first driving member 430, the blocking member 420, and the first connecting member 440. In addition, the first connecting member 440 may be directly used as a connecting rod, with one end slidably connected to one of the blocking member 420 and the first driving member 430, and the other end hingedly connected to the other of the blocking member 420 and the first driving member 430.

[0067] Continue to refer to Figure 8 In some embodiments, the first connecting member 440 is slidably mounted to the mounting base 410. One of the first connecting member 440 and the mounting base 410 is provided with a third guide portion 411, and the other is provided with a third sliding member 443. The third sliding member 443 fits with the third guide portion 411 and slides along the third guide portion 411. Specifically, for example, a groove extending in the up-down direction is provided on the inner side of the second mounting plate 414 as the third guide portion 411. The first connecting member 440 is plate-shaped, and the edge of the first connecting member 440 serves as the third sliding member 443 and is embedded in the third guide portion 411. When the first driving member 430 is driven, the first connecting member 440 is pulled to slide up and down in the third guide portion 411, thereby driving the blocking member 420 to swing.

[0068] Continue to refer to Figures 10 to 13 , and auxiliary reference Figure 6Thus, the blocking device 400 can achieve that when the first driving member 430 is driven in the front-to-back direction, the blocking member 420 swings in a plane defined by the vertical and horizontal directions. Such a blocking device 400 is suitable for use in a carrier 100 without driving power. For example, the carrier 100 is transported in the front-to-back direction by the transport device 200. A protrusion 321 is provided on the first device 300. When the carrier 100 and the first device 300 are docked, the protrusion 321 abuts the second end 431 of the first driving member 430 from the front, driving the fourth end 435 of the first driving member 430 to swing forward clockwise around the second rotating member 415. At the same time, the protrusion 321 pulls the first connecting member 440 downward to slide, thereby pulling the first end 421 of the blocking member 420 upward to swing, thereby switching the blocking member 420 from the blocking position 401 to the release position 402.

[0069] In some embodiments, the first elastic member 450 is an inwardly contracting first elastic member 450, such as a tension spring or an elastic belt. One end of the first elastic member 450 is connected to the mounting base 410, and the other end is connected to the first driving member 430. Specifically, taking the tension spring as an example, one end of the tension spring is connected to the mounting base 410, such as the second mounting plate 414 of the mounting base 410, and the other end of the tension spring is connected to the first driving member 430. More specifically, the tension spring is located at the rear side of the first driving member 430, with one end of the tension spring connected to the rear and upper portion of the second mounting plate 414 relative to the first driving member 430, and the other end of the tension spring is connected above the second rotation hole 434 of the first driving member 430, such as to the fourth end 435 of the first driving member 430. This ensures that the first driving member 430 is reliably pulled rearward, thereby reliably positioning the first end 421 of the blocking member 420 in the blocking position 401.

[0070] It can be imagined that although the above description uses the inward-contracting first elastic member 450 such as a tension spring as the reset member, it is not limited to this. The reset member can also be an outward-expanding first elastic member 450 such as a compression spring, a nitrogen spring, or an oil pressure buffer.

[0071] In addition, it can be imagined that although the above description is that one end of the first elastic member 450 is connected to the mounting base 410 and the other end is connected to the first driving member 430, it is not limited to this. The first elastic member 450 can also be connected to the mounting base 410 at one end and connected to one of the first connecting member 440 or the blocking member 420 at the other end.

[0072] Continue to refer to Figure 7 、 Figure 8In some embodiments, a non-metallic barrier 460 is provided at the first end 421. Specifically, the barrier 460 can be directly fastened to the rear of the first end 421 using a non-metallic fastener (not shown), such as a resin screw or a ceramic screw, to cushion the material 110 blocked by the barrier 420 while preventing metal from coming into contact with the material 110. The barrier 460 can be made of a highly compressible material, such as polyurethane, rubber, or silicone.

[0073] In some embodiments, the second end portion 431 is provided with a rolling element 470. Specifically, the rolling element 470 can be selected from bearings, rollers, and the like, and can be rotatably mounted to the second end portion 431 via a rotating shaft, thereby reducing wear on the second end portion 431 when impacted.

[0074] It is conceivable that, in the above embodiments, for example, the blocking member 420 may include two members, one located on the left and right sides of the mounting base 410, and the first elastic member 450 may also include two members, one located on the left and right sides of the mounting base 410. Correspondingly, the second mounting plate 414 may also include two members on the left and right sides. The two first elastic members 450 are each mounted at one end to one of the second mounting plates 414, and the other end thereof respectively pulls the first driving member 430. In this way, the left-right coordination and balance of the blocking device 400 can be improved.

[0075] Furthermore, while the above embodiment of the blocking device 400 is described as including a blocking member 420, a first driving member 430, a first connecting member 440, and a first elastic member 450, the present invention is not limited thereto. The blocking device 400 may also include only a blocking member and a first elastic member. The blocking member is pivotally mounted to the frame 120 and can be driven by the first device 300 to switch from a blocking position, where it blocks the material 110, to a release position, where it releases the material 110. The first elastic member is configured to drive the blocking member to maintain the blocking position. It is contemplated that the first device 300 may directly drive the blocking member to swing. For example, when the carrier 100 and the first device 300 are docked, the blocking member impacts the first device 300, causing the blocking member to swing. The first device 300 may also swing the blocking member using, for example, a pneumatic cylinder. For example, when the carrier 100 and the first device 300 are docked, the pneumatic cylinder provided in the first device 300 may propel the blocking member to swing.

[0076] In some embodiments, to control the operation or stopping of the carrier 100 being transported, the carrier 100 further includes an emergency stop device 500. The emergency stop device 500 is disposed on the frame 120 and can be switched to be sensed by the sensor 210 of the transport device 200, or disconnected from the sensor 210 to enable the transport device 200 to operate or stop. By providing the emergency stop device 500, the transport device 200 can be conveniently operated or stopped, thereby enabling the carrier 100 to operate or stop.

[0077] Reference Figures 14 to 17 Specifically, the emergency stop device 500 includes an emergency stop member 520 and a sensing portion 530. The emergency stop member 520 and the sensing portion 530 are mounted on the frame 120. To facilitate installation of the emergency stop device 500, the emergency stop member 520 can be mounted on the frame 120 via a mounting base 510. The mounting base 510 is provided on the frame 120, and the emergency stop member 520 is mounted on the mounting base 510 and can be driven to switch between an operating position 501 and a stop position 502. The sensing portion 530 is connected to the emergency stop member 520 and is sensed by a sensor 210 provided on the transport device 200 for transporting the carrier 100 as the emergency stop member 520 switches between the operating position 501 and the stop position 502, or is disconnected relative to the sensor 210, thereby causing the transport device 200 to operate or disconnect.

[0078] In the emergency stop device 500 of this embodiment, since a sensing part 530 is provided which can be sensed by the sensor 210 of the transport device 200 of the transport carrier 100 or be disconnected relative to the sensor 210 as the emergency stop part 520 is switched, the carrier 100 provided with such an emergency stop device 500 does not need a control system and can easily control the operation or stop of the transport device 200.

[0079] It is conceivable that the mounting base 510 can be installed on the rack 120 in any manner as long as it can mount the emergency stop part 520 , for example, it can be installed on the rack 120 by threaded connection, welding, clamping, etc., or it can be directly processed on the rack 120 .

[0080] It is conceivable that the operating position 501 and the stop position 502 of the emergency stop 520 can be any position, as long as the position of the sensing portion 530 can be changed. For example, the position where the emergency stop 520 enables the sensing portion 530 to be sensed by the sensor 210 of the transport device 200 can be used as the operating position 501, and the position where the emergency stop 520 disconnects the sensing portion 530 from the sensor 210 of the transport device 200 can be used as the stop position 502. Furthermore, it should be noted that the operating position 501 and the stop position 502 can also be interchanged. For example, the position where the sensing portion 530 can be sensed by the sensor 210 of the transport device 200 can be used as the stop position 502, and the position where the emergency stop 520 disconnects the sensing portion 530 from the sensor 210 of the transport device 200 can be used as the operating position 501. In this manner, only the control logic of the control system needs to be modified.

[0081] In some embodiments, to facilitate operator control of the emergency stop 520, the emergency stop 520 is mounted on the upper portion of the frame 120 via a mounting base 510, and the sensing unit 530 is mounted on the lower portion of the frame 120. The emergency stop 520 and the sensing unit 530 are connected via a transfer unit 540. Specifically, the emergency stop 520 can be mounted via the mounting base 510 to any location on the upper portion of the frame 120 that is convenient for an operator to directly operate manually, such as a side or top portion of the upper portion of the frame 120. Accordingly, since the sensing unit 530 is used to match the stopping (e.g., emergency stop) or operation (e.g., resumption of operation or normal operation) of the transport device 200, the sensing unit 530 is positioned according to the position of the transport device 200 in transporting the frame 120. Specifically, the sensing unit 530 can be positioned anywhere that can be easily sensed by the sensor 210 of the transport device 200, such as the sides or bottom portion of the lower portion of the frame 120.

[0082] In some embodiments, in order to facilitate the control of the sensing unit 530 via the emergency stop unit 520, the transfer unit 540 includes a flexible member 541, one end 541a of the flexible member 541 being connected to the emergency stop unit 520, and the other end 541b of the flexible member 541 being connected to the sensing unit 530. Specifically, the flexible member 541 may be a flexible member such as a wire rope, a rubber rope, a belt, a synchronous belt, or a chain. In order to guide the trajectory of the flexible member 541, the frame 120 may be provided with a plurality of idler pulleys 542 that are adapted to the shape of the flexible member 541. For example, these idler pulleys 542 may be smooth pulleys capable of guiding a wire rope or a belt, synchronous pulleys capable of guiding a synchronous belt, or sprockets capable of guiding a chain.

[0083] Thus, the transfer part 540 can configure the trajectory of the flexible part 541 according to the specific structure of the rack 120 to prevent interference between the installation space of the transfer part 540 and the rack 120. For example, when the rack 120 is a welded rack 120, these idler wheels 542 can be installed on the rack 120 by welding, so as to easily guide the flexible part 541 from the upper part of the rack 120 to the lower part of the rack 120, thereby connecting the emergency stop part 520 and the sensing part 530.

[0084] Furthermore, it is contemplated that the emergency stop member 520 and the sensing unit 530 may be connected to the flexible member 541 in any manner as long as they are compatible with the flexible member 541. For example, the emergency stop member 520 and the sensing unit 530 may be connected to the flexible member 541 via connecting portions 543, respectively. These connecting portions 543 may be, for example, clamps for clamping a wire rope, belt, or synchronous belt, or pins for connecting a chain. Furthermore, the flexible member 541 may also be directly connected to the emergency stop member 520 and the sensing unit 530, respectively, by various means, such as winding, thread locking, riveting, welding, or clamping.

[0085] It is conceivable that although the flexible part 541 is described as the transfer part 540, it is not limited to this. The transfer part 540 can also choose other connection methods such as a connecting rod (not shown) to connect the emergency stop part 520 and the sensing part 530 respectively.

[0086] Reference Figure 18 、 Figure 19 ,in, Figure 18 The sensing portion 530 and Figure 19 The sensing portion 530 is substantially the same except for the different directions, so they are described together here. Figure 18 、 Figure 19 , and auxiliary reference Figure 14In some embodiments, to facilitate control of the sensing portion 530 and prevent the sensor 210 from erroneously sensing the sensing portion 530 when the transport device 200 transports the rack 120, the sensing portion 530 includes a sensing member 531 and a blocking member 532. At least one of the blocking member 532 and the sensing member 531 is connected to the emergency stop member 520 and is driven as the emergency stop member 520 switches between the operating position 501 and the stop position 502, causing the blocking member 532 to block the sensing member 531 or reveal the sensing member 531 relative to the blocking member 532. Specifically, the sensing member 531 is fixed to the rack 120. The blocking member 532 is connected to the other end 541b of the flexible member 541. As the emergency stop member 520 switches between the operating position 501 and the stop position 502, the blocking member 532 is pulled by the flexible member 541 and switches position relative to the sensing member 531, revealing or blocking the sensing member 531. The shielding member 532 is plate-shaped. The frame 120 is further provided with a slide groove 533 below the sensing member 531. At least the edge of the shielding member 532 is inserted into the slide groove 533 and is slidable within the slide groove 533. The shielding member 532 is connected to the emergency stop member 520 disposed on the upper portion of the frame 120 via a clamp serving as a connecting portion 543 and a steel wire rope, for example, serving as a flexible member 541. When the emergency stop member 520 switches between the operating position 501 and the stop position 502, the steel wire rope, serving as the flexible member 541, is pulled, thereby causing the shielding member 532 to slide within the slide groove 533, for example, in the forward and backward direction in the accompanying drawings, thereby shielding the sensing member 531 or revealing the sensing member 531. When the sensing portion 530 is exposed, it can be sensed by the sensor 210 of the transport device 200, thereby inputting a signal (e.g., an ON control signal) to the transport device 200 to continue operation. When the sensing element 531 is blocked by the blocking member 532, the sensor 210 cannot sense the sensing element 531, and the sensor 210 can input an emergency stop signal (e.g., an OFF control signal) to the transport device 200. Thus, the transport device 200 can decide whether to continue operation or make an emergency stop based on whether the sensor 210 inputs a control signal.

[0087] Therefore, the carrier 100 of the present invention can also easily control the transport device 200 to stop or continue operation using the mechanical emergency stop device 500. In addition, the emergency stop device 500 can be easily installed at any position on the frame 120 via the transfer portion 540, so the emergency stop device 500 can be installed according to the operator's operating position.

[0088] It can be imagined that although the emergency stop member 520 is connected to the shielding member 532 through the flexible member 541 and drives the shielding member 532 to slide in the slide groove 533, it is not limited to this. For example, the emergency stop member 520 can also be connected to the sensing member 531 through the flexible member 541, the shielding member 532 is installed at the lower part of the frame 120, and the slide groove 533 is set on the upper part of the shielding member 532. The emergency stop member 520 pulls the sensing member 531 through the flexible member 541, so that the sensing member 531 is exposed relative to the shielding member 532 or is covered by the shielding member 532.

[0089] Furthermore, to reduce the driving stroke of the emergency stop 520, the shielding member 532 and the sensing member 531 can also be configured to be able to slide, and the shielding member 532 and the sensing member 531 can be connected via a transmission mechanism such as a gear rack, thereby enabling interlocking movement. Alternatively, the emergency stop 520 can be connected to both the shielding member 532 and the sensing member 531. For example, the emergency stop 520 can be connected to two flexible members 541, and the two flexible members 541 are respectively connected to the shielding member 532 and the sensing member 531, and guided by different intermediate idler pulleys 542, so that their sliding directions are opposite.

[0090] In some embodiments, an elastic driving member 550 is further included. The elastic driving member 550 is configured to drive the shielding member 532 or the sensing member 531 when the emergency stop member 520 switches from the operating position 501 to the stop position 502, so that the shielding member 532 blocks the sensing member 531 or the sensing member 531 is exposed from the shielding member 532. The following description uses the position where the emergency stop member 520 enables the sensing portion 530 to be sensed by the sensor 210 of the transport device 200 as an example of the operating position 501, and the position where the emergency stop member 520 disconnects the sensing portion 530 from the sensor 210 of the transport device 200 as the stop position 502. Furthermore, in this embodiment, the flexible member 541 is connected to the shielding member 532 as an example. Specifically, in this embodiment, one end of the elastic driving member 550 abuts the frame 120, and the other end abuts the shielding member 532. For example, to facilitate the elastic driving member 550 abutting the shielding member 532, a protruding sheet metal member 534 may be provided on the shielding member 532. A mounting shaft 535 may also be provided to mount the elastic driving member 550. When the emergency stop member 520 is in the operating position 501, the emergency stop member 520 pulls on the flexible member 541 to drive the shielding member 532. Simultaneously, the elastic driving member 550 is compressed, thereby exposing the sensing member 531 from the shielding member 532, allowing the sensor 210 of the transport device 200 to sense the sensing member 531. When the emergency stop member 520 switches from the running position 501 to the stop position 502 (i.e., when the emergency stop member 520 switches positions in the direction of releasing the flexible member 541), the compression of the elastic driving member 550 is released, thereby driving the shielding member 532 to slide in the sliding groove 533 (in the Figure 18 The elastic driving member 550 is provided so that the shielding member 532 can reliably shield the sensing member 531 or allow the sensing member 531 to be exposed from the shielding member 532, thereby improving the reliability of the operation or stop of the transport device 200.

[0091] It is contemplated that the elastic driving member 550 may be an outward-expanding elastic member, such as a coil spring, a nitrogen spring, or an oil pressure buffer, or an inward-contracting elastic member, such as a tension spring or an elastic belt. Those skilled in the art may appropriately adjust the relative positions of the elastic driving member 550 and the flexible member 541 based on the actual installation space.

[0092] It can be imagined that although the above description is made using the elastic driving member 550 driving the shielding member 532 as an example, it is not limited to this. For example, the elastic driving member 550 can also drive the sensing member 531 to make the shielding member 532 cover the sensing member 531 or make the sensing member 531 appear from the shielding member 532.

[0093] In addition, although the above description is based on the example that the sensing part 530 has a blocking member 532 and a sensing member 531, it is not limited to this. In some embodiments, for example, the sensing part 530 may only include the sensing member 531, and the sensing member 531 is connected to the emergency stop member 520, and is sensed by the sensor 210 as the emergency stop member 520 switches between the running position 501 and the stop position 502, or is disconnected relative to the sensor 210.

[0094] In some embodiments, to facilitate operators controlling the stopping or starting of the transport device 200 from various directions, the emergency stop members 520 and the shielding members 532 are provided at multiple locations. Each emergency stop member 520 is connected to a shielding member 532 and actuates the shielding member 532 to cause the shielding member 532 to block the sensing member 531 or to reveal the sensing member 531 relative to the shielding member 532. Specifically, for example, a mounting base 510 may be provided in the front and rear directions of the frame 120, each mounting base 510 being provided with an emergency stop member 520. Accordingly, the sensing portion 530 includes one sensing member 531 and two shielding members 532. The emergency stop members 520 located in the front and rear directions of the frame 120 are connected to two shielding members 532, respectively. Thus, the shielding members 532 can be independently actuated to cause the shielding member 532 to block the sensing member 531 or to reveal the sensing member 531 relative to the shielding member 532. Thus, in this embodiment, the operator can conveniently operate the emergency stop member 520 at various positions, thereby improving the safety of the transport device 200. Furthermore, because the sensing member 531 is fixed relative to the frame 120, there is no need to adjust the position of the sensor 210 relative to the sensing member 531, nor is there a need to increase the number of sensors 210. This not only makes it easier to control the operation or stop of the transport device 200, but also does not increase additional costs.

[0095] Continue to refer to Figure 15 、 Figure 16 , and auxiliary reference Figure 14 、 Figure 17 , the emergency stop component 520 is described in detail below.

[0096] As described above, as long as the position of the sensing portion 530 can be changed, the operating position 501 and the stop position 502 can be any position. It is conceivable that the emergency stop 520 can be switched from the operating position 501 to the stop position 502 by, for example, sliding, swinging, or rotating. For example, the emergency stop 520 can be slidably mounted to the mounting seat 510 to slide and switch from the operating position 501 to the stop position 502; or the emergency stop 520 can also be mounted on the mounting seat 510 by, for example, a hinged manner to swing and switch from the operating position 501 to the stop position 502; or the emergency stop 520 can also be set to rotate around its own axis relative to the mounting seat 510 to rotate and switch from the operating position 501 to the stop position 502; or the emergency stop 520 and the mounting seat 510 can also be assembled as a whole into the form of a manual quick clamp.

[0097] In some embodiments, to ensure that the emergency stop member 520 remains stably in the operating position 501 or the stop position 502, the emergency stop device 500 may further include an elastic limiting member 560. The elastic limiting member 560 is configured to limit the emergency stop member 520 when the emergency stop member 520 is in the operating position 501 or the stop position 502. Specifically, the elastic limiting member 560 may be an elastic pin, a roller plunger, a ball plunger, or the like. Furthermore, the elastic limiting member 560 may be mounted on either the mounting base 510 or the emergency stop member 520.

[0098] For example, to facilitate installation of the elastic limiting member 560, in some embodiments, the elastic limiting member 560 is mounted on the mounting base 510, and the emergency stop member 520 is provided with a first groove 521 and a second groove 522 spaced apart along the switching direction. When the emergency stop member 520 is in the operating position 501, the elastic limiting member 560 is inserted into the first groove 521; when the emergency stop member 520 is in the stop position 502, the elastic limiting member 560 is inserted into the second groove 522. This facilitates installation of the elastic limiting member 560 while stably maintaining the emergency stop member 520.

[0099] In some embodiments, to facilitate switching of the emergency stop member 520, a guide portion 511 is provided on the mounting base 510, and the emergency stop member 520 is slidably mounted within the guide portion 511. Specifically, for example, a guide hole 512 may be provided on the guide portion 511. Accordingly, the emergency stop member 520 is configured to be substantially axial, with a first groove 521 and a second groove 522 spaced apart along the axial direction of the emergency stop member 520. The emergency stop member 520 slides within the guide hole 512 of the mounting base 510. The elastic limiting member 560 is mounted on the mounting base 510 and partially extends into the guide hole 512 along the radial direction of the guide hole 512, inserting into the first groove 521 or the second groove 522. This facilitates the sliding switching of the emergency stop member 520 between the operating position 501 and the stop position 502.

[0100] In addition, although the example of limiting the emergency stop member 520 by the elastic limiting member 560 is described, it is not limited to this. For example, the emergency stop member 520 can also be stabilized in the operating position or the stop position by means of a connecting rod (for example, when the emergency stop member 520 and the mounting base 510 are assembled into the form of a manual quick clamp).

[0101] Therefore, the emergency stop device 500 as described above is provided with a sensing portion 530 that can be sensed by the sensor 210 of the transport device 200 of the transport carrier 100 or be disconnected relative to the sensor 210 as the emergency stop part 520 is switched. Therefore, the carrier 100 does not need a control system and can easily control the operation or stop of the transport device 200.

[0102] In addition, since the emergency stop member 520 is connected to the sensing portion 530 via the transfer portion 540 , such as the flexible member 541 , the emergency stop member 520 can be set at any position that is convenient for the operator to operate, thereby improving the safety of the transport device 200 .

[0103] Furthermore, since the emergency stop member 520 can be provided in multiple locations and each corresponds to a sensing member 531 , it is not only easy to control the operation or stop of the transport device 200 , but also does not require additional cost.

[0104] Furthermore, since the elastic limiting member 560 is provided, the emergency stop member 520 can be stably maintained in the operating position 501 or the stopping position 502 , thereby improving the reliability of the operation or stopping (continuing operation) of the conveying device 200 .

[0105] It is conceivable that the sensing portion 530 sensed by the sensor 210, such as the sensing element 531 of the sensing portion 530, can be a sheet-shaped or strip-shaped sensing element. Accordingly, the sensor 210 can be a sensor such as a photoelectric sensor, an ultrasonic sensor, a laser obstacle avoidance sensor, a proximity switch, or a sensor with a camera such as a smart camera, a CCD, a barcode scanner, or a barcode scanner box. Furthermore, the sensor 210 can also be a travel switch, etc.

[0106] In some embodiments, to improve sensing accuracy, the sensor 210 can be a sensor 210 with a camera, and the sensing unit 530 can be provided with an identification unit (not shown) that can be recognized by the camera. Specifically, for example, the sensor 210 can be a barcode scanner or a barcode scanning box installed on an AGV vehicle serving as the transport device 200. Correspondingly, the identification unit of the sensing unit 530 can be a QR code provided on the lower portion of the sensing element 531. This can improve sensing accuracy, thereby improving the reliability of the emergency stop device 500 in controlling the operation or stop of the transport device 200.

[0107] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
