Referring to fig. 1 and 2, the carrier 100 of the present invention has a rack 120 for holding the material 110, and the rack 120 is carried by a carrying device 200 and is docked with a first apparatus 300 for processing the material 110, so that the material 110 is transferred between the carrier 100 and the first apparatus 300. This frame 120 is provided with: a conveying part 130, a docking part 140 and a blocking device 400, wherein the conveying part 130 is used for conveying the material 110; the docking portion 140 is connected to at least one end of the conveying portion 130, and when the carrier 100 is docked with the first apparatus 300, is connected to the power system 310 of the first apparatus 300, and drives the conveying portion 130 to convey the material 110; the blocking device 400 is disposed in a direction (front-back direction in fig. 1 and 2) in which the conveying portion 130 conveys the material 110, and is driven by the first apparatus 300 to release the blocking of the material 110 when the carrier 100 and the first apparatus 300 are docked.

In the present embodiment, since the conveyor 130 for conveying the material 110 and the stopper 400 for stopping the material 110 are driven by the first equipment 300 docked with the carrier 100 on the carrier 100, it is not necessary to provide an independent driving system on the carrier 100, and the cost of the carrier 100 can be reduced, and since one set of the power system 310 of the first equipment 300 can be adapted to a plurality of sets of carriers 100 without independent driving systems, the cost of the production line can be greatly reduced.

It is contemplated that material 110 should be broadly understood, and material 110 may be exemplified by: the work, products, and the like to be processed may be directly placed on the frame 120, or may be loaded on the frame 120 by a jig, a tray, or the like. Further, processing is to be understood in a broad sense and can be any process in the production of a workpiece, product, such as machining, welding, component assembly, coating, inspection, etc.; and the method can also be an auxiliary procedure in the production process of workpieces and products, such as shutdown treatment, manual intervention, waste treatment and the like. The first apparatus 300 is any apparatus that performs these processes or auxiliary processes. In addition, the equipment should be interpreted broadly as long as it has an independent power system, and is not particularly limited, and may be, for example, an independent equipment fixed on the ground, an independent equipment having a flow line, an elevator, etc.

It is contemplated that the frame 120 may be any type of frame 120 as long as it can carry the material 110 and be handled by the handling device 200, and from a material perspective, for example: a rack made of profile welding, a rack made of profile, or a combined rack made of profile welding and profile, and the like; from the structural point of view, for example, there may be mentioned: a frame having feet for supporting, a frame having casters, or a frame having feet and casters, etc.; from the viewpoint of storage space, for example, there may be mentioned: a rack on which the material 110 can be placed in a single layer, a rack on which the material 110 can be placed in a plurality of layers in the up-down direction, a rack on which the material 110 can be placed in a plurality of layers in the left-right direction and a plurality of layers in the up-down direction, and the like.

As long as the carrier 100 can be transported, the form of the transport device 200 is not particularly limited, and examples thereof include: an AGV vehicle (for example, the transport apparatus 200 shown in fig. 1 and 2), various robots mounted on a travel rail, for example, transport robots such as a three-axis robot and a six-axis robot, and various transport lines such as a roller line and a plate chain transport line having independent power. In the case of manual operation, the operator may be understood as a special conveyance device.

It is understood that, according to the docking of the carrier 100 and the first apparatus 300, the docking covers the whole process from the ready docking to the completion of the docking of the carrier 100 and the first apparatus 300, which includes: a trend of starting docking, in docking, at the completion of docking, and in a stable docking state after the completion of docking.

It is conceivable that the conveyor 130 is driven to convey the material 110, and various conveying cases are included, for example, both the case where the material 110 is conveyed from the carrier 100 to the first equipment 300 and the case where the material is conveyed from the first equipment 300 to the carrier 100.

Referring to fig. 3 with continued reference to fig. 1 and 2, in some embodiments, in order to smoothly and continuously convey the material 110, the conveying portion 130 includes a material flow line 131, one end of the material flow line 131 is provided with a first transmission shaft 132, and the connection portion 140 is connected with the first transmission shaft 132. Specifically, the material 110 may be placed on the material flow line 131, after the vehicle 100 is docked with the first apparatus 300, the material flow line 131 is connected to the power system 310 disposed on the first apparatus 300 through the docking portion 140, so as to be driven by the power system 310 on the first apparatus 300, and the material 110 is conveyed to the first apparatus 300 while being placed, and the material flow line 131 may be selected from, for example: belt line, drum line, roller chain line, double speed chain line, plate chain line, etc. Accordingly, the transfer unit 130 can directly transfer the material 110 to the first facility 300 even after being driven while the material 110 is placed thereon.

It is contemplated that the first transmission shaft 132 may be either a support shaft directly supporting and transmitting, for example, a pulley, a timing pulley, a drum, a sprocket, etc., or a transmission shaft connected to these support shafts through, for example, a belt transmission, a chain transmission, a gear transmission, a belt transmission, a coupling, etc.

In some embodiments, to achieve smooth docking of the power system 310 and the docking portion 140 of the first apparatus 300, 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, and correspondingly, the motor 311 of the power system 310 of the first apparatus 300 and the second engaging member 312 capable of engaging with the first engaging member 142 are connected and drive 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 with each other, and for example, a socket head, a pawl, and the like can be selected as the first engaging member 142, and for example, a hexagon socket shaft fitted to the socket head, a pawl fitted to the pawl, and the like can be selected as the second engaging member 312. In order to engage or disengage the second engaging member 312 with or from the first engaging member 142, so as to achieve connection or disconnection between the power system 310 and the connection unit 140, the power system 310 further includes a driving element 313, such as a driving cylinder or the like, for driving the motor 311 to switch positions, and 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 drawing) of the first engaging member 142. Thereby, smooth docking of the power system 310 and the docking portion 140 of the first apparatus 300 can be achieved. When the carrier 100 is carried by the carrying device 200 and is docked with the first apparatus 300, the driving element 313 of the power system 310 drives the motor 311 to switch positions, for example, the driving motor 311 extends out, and the second engaging member 312 is engaged with the first engaging member 142, so that when the motor drives the second engaging member 312 to rotate, the first engaging member 142 and the first transmission shaft 132 can be driven to rotate, and the stream line 131 of the transmission portion 130 can be driven to rotate.

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

Referring to fig. 4 and 5, in some embodiments, in order to achieve smooth connection between the power system 310 of the first apparatus 300 and the connection portion 140, the connection 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 apparatus 300 may be, for example, a power system 310 driven by a motor 311, and the motor 311 of the power system 310 is connected with a second gear 315 capable of meshing with the first gear 141 and drives the second gear 315 to rotate. In order to engage or disengage the second gear 315 with or from the first gear 141 to achieve connection or disconnection between the power system 310 and the connection section 140, the power system 310 further includes a driving element 313, such as a driving cylinder or the like, for driving the motor 311 to switch positions, and the driving element 313 drives the second gear 315 to approach the first gear 141 along a radial direction (in the up-down direction in the drawing) of the first gear 141. After the carrier 100 is carried by the carrying device 200 and is docked with the first apparatus 300, the driving element 313 of the power system 310 drives the motor 311 to switch positions, for example, the motor 311 extends out, and the second gear 315 is meshed with the first gear 141, so that when the motor 311 drives the second gear 315 to rotate, the first gear 141 and the first transmission shaft 132 can be driven to rotate, and the stream line 131 of the conveying part 130 can be driven to rotate.

Since the conveying unit 130 has no independent driving system, when the carrier 100 is conveyed by the conveying device 200, the material 110 may move due to the rotation of the conveying unit 130. Further, due to inertia of conveyance or the like, the material 110 may slip off the conveyor 130. In the present invention, the stopper 400 is provided to prevent the material 110 from falling off the carrier 100 during the process of transporting the carrier 100.

The blocking device 400 is described in more detail below with reference to fig. 6-13.

Referring to fig. 6, 7, 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. Wherein the blocking member 420 is swingably mounted to the frame 120, the blocking member 420 is driven by the first apparatus 300, for example, by the protrusion 321 of the first apparatus 300, and is switched from the blocking position 401 (refer to fig. 9 and 10) for blocking the material 110 to the release position 402 (refer to fig. 12) for releasing the blocking of the material 110. The first driving member 430 is swingably mounted to the frame 120. The first link 440 is connected to the blocking member 420 and the first driving member 430, respectively, and at least one of a first connection position 403 (see fig. 10) where the first link 440 is connected to the blocking member 420 and a second connection position 404 (see fig. 11) where the first link 440 is connected to the first driving member 430 may be changed. When the carrier 100 and the first apparatus 300 are docked, the first driving member 430 is driven by the first apparatus 300 to swing, and is switched from the blocking position 401 to the release position 402 by pulling the first connecting member 440 so that the blocking member 420 is driven to swing. The first resilient member 450 is configured to actuate the blocking member 420 such that the blocking member 420 is in the blocking position 401.

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 releasing position 402 in a linkage manner, and further, since the first elastic member 450 is provided to drive the first driving member 430 so that the blocking member 420 is located at the blocking position 401, the material 110 carried by the carrier 100 can be blocked even if the carrier 100 has no driving system.

It is contemplated that, with reference to fig. 9, 10, blocking position 401 refers to a position where blocking member 420 restricts passage of, for example, material 110 blocked thereby; referring to fig. 12, the release position 402 refers to a position where the blocking member 420 allows passage of, for example, material 110 blocked by it.

In some embodiments, to facilitate the assembly and disassembly of the barrier 400, the barrier 400 may further include a mounting base 410, and the mounting base 410 may be a single component integrally formed or a component 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, the first elastic member 450, and the like to the frame 120 through the mounting base 410. Specifically, the blocking member 420 is swingably mounted to the mounting base 410, and the first end 421 of the blocking member 420 extends out of the mounting base 410 and is switchable between a blocking position 401 (refer to fig. 9 and 10) and a release position 402 (refer to fig. 12) with the swinging of the blocking member 420; the first driving member 430 is swingably mounted to the mounting base 410, and a second end 431 of the first driving member 430 extends out of the mounting base 410.

It is contemplated that although the above description describes the first end 421 of the blocking member 420 extending out of the mounting base 410, those skilled in the art should understand that: the extension of the first end 421 out of the mounting base 410 is not limited to the first end 421 having to extend out of the mounting base 410 entirely, but means that the first end 421 extends to a position where the mounting base 410 does not interfere with the material 110, for example, when the mounting base 410 has 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, that is, the first end 421 extends out of the mounting base 410.

Also, while the second end 431 of the first driving member 430 is illustrated as extending out of the mounting base 410, those skilled in the art should understand broadly that: the extension of the second end 431 out of the mounting base 410 is not limited to the second end 431 having to extend entirely out of the mounting base 410, but rather means that the second end 431 extends to a point where the mounting base 410 does not interfere with, for example, docking equipment, e.g., when the mounting base 410 has a U-shaped channel and the docking equipment partially extends into the U-shaped channel of the mounting base 410, meaning that the second end 431 extends out of the mounting base 410.

Referring to fig. 8 and 10, in some embodiments, the first connection member 440 and the blocking member 420 are slidably connected such that the first connection position 403 can be changed. Specifically, for example, the mounting base 410 is provided with a first mounting plate 412, a first rotating member 413 such as a rotating pin is mounted on the first mounting plate 412, the first rotating member 413 extends in the front-rear direction, and correspondingly, the first intermediate portion 423 of the blocking member 420 is provided with a first rotating hole 424, and the first rotating hole 424 is fitted with the first rotating member 413 and rotates about the first rotating member 413. The first end portion 421 is provided at an upper portion of the stopper 420, is connected to an upper end of the first intermediate portion 423, and extends outward at an acute angle R1, for example, approximately 60 ° with respect to the upper end of the first intermediate portion 423. The stopper 420 is provided at a lower portion thereof with a third end portion 425, and the third end portion 425 is connected to a lower end of the first intermediate portion 423 and extends outward at an acute angle R2, for example, approximately 60 ° with respect to the lower end of the first intermediate portion 423. Since the upper portion of the first link 440 is slidably connected to the third end portion 425, the first end portion 421 of the blocking member 420 can be swung in the vertical direction by rotating the blocking member 420 about the first rotating member 413 while the third end portion 425 of the blocking member 420 slides relative to the first link 440 in conjunction with the first link 440 driven by the first driving member 430. When first end 421 swings downward, first end 421 is in blocking position 401, which can restrain, for example, material 110 to prevent it from falling. When the first end 421 swings upward, the first end 421 is in the release position 402, allowing, for example, the material 110 to be transferred. By providing the first link 440 and the stopper 420 to be slidably coupled so that the first coupling position 403 is changed, it is possible to prevent the first link 440 and the stopper 420 from being stuck, thereby smoothly swinging the stopper 420.

In some embodiments, one of the first connector 440 and the blocking member 420 is provided with a first guide 422, and the other is provided with a first slider 441, and the first slider 441 and the first guide 422 are fitted and slide along the first guide 422. This allows the first connector 440 and the stopper 420 to be smoothly and slidably connected to each other. For example, a groove portion may be provided as the first guide portion 422 at the third end portion 425 of the blocking member 420, a sliding pin may be provided as the first slider 441 at the first link 440, and the first slider 441 may be inserted into the first guide portion 422 in the front-rear direction and slid along the first guide portion 422. Thus, when the first link 440 is driven, for example, in the up-down direction, the first slider 441 simultaneously pulls the stopper 420 in the up-down direction, thereby swinging the stopper 420.

Although the first guide 422 and the first slider 441 are provided to the stopper 420 and the first connecting member 440, the present invention is not limited thereto, and the first guide 422 and the first slider 441 may be provided to the stopper 420.

Referring to fig. 11 and 13, in some embodiments, the first link 440 and the first driving member 430 are slidably coupled such that the second coupling position 404 can be changed. Specifically, for example, the mounting base 410 is provided with a second mounting plate 414, the second mounting plate 414 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, i.e., the second rotating member 415 is substantially perpendicular to the first rotating member 413, and in correspondence with this, the second intermediate portion 433 of the first driving member 430 is provided with a second rotating hole 434, and the second rotating hole 434 and the second rotating member 415 are fitted to rotate around the second rotating member 415. The second end portion 431 is provided at a lower portion of the first driving member 430, is connected to a lower end of the second intermediate portion 433, and extends outwardly at a substantially acute angle R3, e.g., 60 °, relative to the lower end of the second intermediate portion 433. The upper portion of the first driving member 430 is provided with a fourth end portion 435, the fourth end portion 435 being connected to the upper end of the second intermediate portion 433 and extending outwardly at a substantially acute angle R4, for example, at an angle of 60 ° with respect to the upper end of the second intermediate portion 433. The lower portion of the first link 440 and the fourth end 435 are slidably coupled, thereby enabling the first link 440 to be pulled as the first driving member 430 swings.

In some embodiments, one of the first connecting member 440 and the first driving member 430 is provided with the second guiding portion 432, and the other is provided with the second sliding member 442, and the second sliding member 442 and the second guiding portion 432 are adapted to slide along the second guiding portion 432. This enables the first connector 440 and the first driver 430 to be smoothly slidably connected to each other. For example, a groove portion may be provided as the second guide portion 432 at the fourth end 435 of the first driving member 430, a slide pin may be provided as the second slider 442 at the first link 440, and the second slider 442 may be inserted into the second guide portion 432 in the left-right direction (the direction perpendicular to the paper surface in fig. 11 and 13) and slid along the second guide portion 432. Thus, when the first driving member 430 is driven in the front-rear direction, the first driving member 430 rotates about the second rotating member 415, and the fourth end 435 swings and pulls the first link 440, thereby swinging the blocking member 420.

Although the second guide part 432 and the second slider 442 are described above as being provided to the first driving member 430 and the first link 440, the present invention is not limited thereto, and the second guide part 432 and the second slider 442 may be provided to the first link 440 and the first driving member 430, respectively.

It is conceivable that the above though in terms of: the first connecting element 440 is slidably connected to the blocking element 420 and the first driving element 430, respectively, so as to change the first connection position 403 at which the first connecting element 440 is connected to the blocking element 420 and the second connection position 404 at which the first connecting element 440 is connected to the first driving element 430, respectively, thereby achieving the mutual linkage of the first driving element 430, the blocking element 420 and the first connecting element 440. For example, the first connecting member 440 may be slidably connected to only the blocking member 420 (i.e., the first connecting position 403 may be changed), and the first connecting member 440 is hinged to the first driving member 430 through a link member (not shown), so that the first driving member 430, the blocking member 420 and the first connecting member 440 are linked to each other. Alternatively, the first connecting member 440 may be slidably connected to only the first driving member 430 (i.e., the second connection position 404 may be changed), and the first connecting member 440 is hinged to the blocking member 420 through a link member (not shown), so that the first driving member 430, the blocking member 420 and the first connecting member 440 are linked to each other. In addition, the first connecting member 440 may be directly used as a link member, one end of which is slidably connected to one of the blocking member 420 and the first driving member 430, and the other end of which is hinged to the other of the blocking member 420 and the first driving member 430.

With continued reference to fig. 8, in some embodiments, the first connector 440 is slidably mounted to the mounting base 410, one of the first connector 440 and the mounting base 410 is provided with a third guide 411, the other is provided with a third slider 443, and the third slider 443 and the third guide 411 are fitted and slid along the third guide 411. Specifically, for example, a groove portion extending in the up-down direction is provided as the third guide portion 411 on the inner side of the second mounting plate 414, the first link 440 has a plate shape, an edge of the first link 440 serves as the third slider 443 and is embedded in the third guide portion 411, and when the first driving member 430 is driven, the first link 440 is pulled to slide up and down in the third guide portion 411, thereby driving the blocking member 420 to swing.

With continuing reference to fig. 10 to 13 and with additional reference to fig. 6, the blocking device 400 is thereby enabled to effect that the blocking member 420 swings in a plane composed of the up-down direction and the left-right direction when the first driving member 430 is driven in the front-rear direction. Such a stopper 400 is suitable for use in a vehicle 100 without driving power, for example, the vehicle 100 is transported in the front-rear direction by the transporting device 200, and a protruding block 321 and the like are provided on the first device 300, and when the vehicle 100 and the first device 300 are docked, the protruding block 321 abuts against the second end 431 of the first driving member 430 from the front direction, and the fourth end 435 of the first driving member 430 is driven to swing clockwise around the second rotating member 415 toward the front direction, and at the same time, the first connecting member 440 is pulled to slide downward, and thus the first end 421 of the stopper 420 is pulled to swing upward, so that the stopper 420 is switched from the stopping position 401 to the releasing position 402.

In some embodiments, the first elastic member 450 is an inwardly contracting type first elastic member 450, such as a tension spring, an elastic belt, etc., and has one end connected to the mounting base 410 and the other end connected to the first driving member 430. Specifically, taking a tension spring as an example, one end of the tension spring is connected to the mounting base 410, for example, to 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, a tension spring is located at the rear side of the first driving member 430, one end of the tension spring is connected to the second mounting plate 414 at the upper rear side with respect to the first driving member 430, and the other end of the tension spring is connected to the first driving member 430 above the second rotation hole 434, for example, the fourth end 435 of the first driving member 430. Thereby, the first driving member 430 can be reliably pulled in the rear direction, and thus the first end 421 of the blocking member 420 can be reliably placed in the blocking position 401.

Although the first elastic member 450 of the inward contracting type such as a tension spring has been described above as the restoring member, the present invention is not limited thereto, and the restoring member may be the first elastic member 450 of the outward expanding type such as a compression spring, a nitrogen spring, and an oil damper.

Further, although the first elastic member 450 is described above as having one end connected to the mounting base 410 and the other end connected to the first driving member 430, the present invention is not limited thereto, and the first elastic member 450 may have one end connected to the mounting base 410 and the other end connected to one of the first connecting member 440 or the blocking member 420.

With continued reference to fig. 7 and 8, in some embodiments, the first end 421 is provided with a blocking member 460 made of a non-metallic material. Specifically, the blocking member 460 can be directly locked to the rear of the first end 421 by a locking member (not shown) made of a non-metal material, such as a resin screw or a ceramic screw, so as to buffer the material 110 blocked by the blocking member 420 and prevent the metal material from contacting the material 110. The blocking member 460 may be made of a material with high compressibility, such as polyurethane, rubber, or silicone.

In some embodiments, the second end 431 is provided with a roller 470. Specifically, the rolling member 470 may be selected from rolling members 470 such as bearings, rollers, etc., and is rollably mounted to the second end portion 431 through a rotating shaft, whereby abrasion of the second end portion 431 when struck can be reduced.

It is contemplated that, in the above embodiments, for example, the blocking member 420 may include two pieces respectively located at the left and right sides of the mounting base 410, the first elastic member 450 may also include two pieces respectively located at the left and right sides of the mounting base 410, and correspondingly, the second mounting plate 414 may also include two pieces at the left and right sides, and the two pieces of the first elastic member 450 are respectively mounted at one end to one of the second mounting plates 414 and at the other end to respectively pull the first driving member 430. This improves the left-right coordination and balance of the baffle device 400.

Further, in the above embodiment of the barrier device 400, although the barrier device 400 has: the blocking member 420, the first driving member 430, the first connecting member 440 and the first elastic member 450 are exemplified and not limited thereto, and the blocking device 400 may also include only: a blocking member swingably mounted to the frame 120, the blocking member being drivable by the first apparatus 300 to switch from a blocking position to block the material 110 to a releasing position to release the blocking of the material 110; the first resilient member is configured to drive the blocking member to the blocking position. It is contemplated that the first device 300 may have the blocking member directly driven to swing, for example, when the vehicle 100 and the first device 300 are docked, the blocking member collides with the first device 300 and swings thereby. The first apparatus 300 may also swing the stopper by, for example, an air cylinder, and for example, when the vehicle 100 and the first apparatus 300 are docked, the stopper is pushed to swing by the air cylinder provided in the first apparatus 300.

In some embodiments, in order to control the operation or stop of the carrier 100 being transported, the carrier 100 further includes an emergency stop device 500, and 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 be switched off relative to the sensor 210 to operate or stop the transport device 200. By providing the scram device 500, the vehicle 100 can be operated or stopped by easily operating or stopping the transport device 200 in operation.

Referring to fig. 14 to 17, specifically, the scram apparatus 500 includes: the scram 520 and the sensing part 530, and the scram 520 and the sensing part 530 are mounted to the frame 120, and the scram 520 may be mounted to the frame 120 through the mounting seat 510 in order to facilitate the mounting of the scram device 500. The mounting seat 510 is disposed on the frame 120, the hard stop 520 is mounted to the mounting seat 510 and can be driven to switch between the operation position 501 and the stop position 502, the sensing part 530 is connected to the hard stop 520 and is sensed by the sensor 210 disposed on the carrying device 200 for carrying the vehicle 100 or is disconnected with respect to the sensor 210 as the hard stop 520 is switched between the operation position 501 and the stop position 502, so that the carrying device 200 is operated or disconnected.

In the emergency stop device 500 of the present embodiment, since the sensor unit 530 is provided which can be sensed by the sensor 210 of the transport device 200 which transports the vehicle 100 or is disconnected from the sensor 210 in accordance with the switching of the emergency stop 520, the vehicle 100 provided with the emergency stop device 500 can easily control the operation or stop of the transport device 200 without a control system.

It is contemplated that the mounting base 510 may be mounted to the frame 120 in any manner, such as by being threaded, welded, snapped, etc., or may be machined directly into the frame 120, as long as the hard stop 520 is mounted thereto.

It is contemplated that the operating position 501 and the stopping position 502 of the hard stop 520 may be any position as long as the position of the sensing portion 530 can be changed. For example, a position where the sensing part 530 can be sensed by the sensor 210 of the carrying device 200 with the scram 520 may be the operating position 501, and a position where the sensing part 530 is disconnected with respect to the sensor 210 of the carrying device 200 with the scram 520 may be the stopping position 502. It should be noted that the operating position 501 and the stop position 502 may be interchanged, for example, a position at which the sensor unit 530 can be sensed by the sensor 210 of the transport apparatus 200 is defined as the stop position 502, and a position at which the sensor unit 530 is disconnected from the sensor 210 of the transport apparatus 200 by the scram 520 is defined as the operating position 501. In this way, only the control logic of the control system needs to be modified.

In some embodiments, to facilitate operator control of the crash stop 520, the crash stop 520 is mounted to an upper portion of the frame 120 by a mounting base 510, the sensing part 530 is mounted to a lower portion of the frame 120, and the crash stop 520 and the sensing part 530 are connected by a transition part 540. Specifically, the crash stop 520 may be mounted to the upper portion of the frame 120 via the mounting base 510 at any location that facilitates direct manual operation by an operator, such as to a side of, or to the top of, the upper portion of the frame 120. In response to this, since the sensing part 530 is used to match the stop (e.g., emergency stop) or operation (e.g., recovery operation or normal operation state) of the carrying device 200, the sensing part 530 is disposed according to the position of the carrying device 200 carrying the rack 120, and particularly, the sensing part 530 may be disposed at any place that can be conveniently sensed by the sensor 210 of the carrying device 200, such as the sides or the bottom of the lower portion of the rack 120.

In some embodiments, in order to easily control the sensing part 530 through the crash stop 520, the transferring part 540 includes a flexible member 541, one end 541a of the flexible member 541 is connected to the crash stop 520, and the other end 541b of the flexible member 541 is connected to the sensing part 530. Specifically, the flexible element 541 may be a flexible element such as a steel wire rope, a rubber rope, a belt, a timing belt, a chain, etc., and in order to guide the track of the flexible element 541, a plurality of idle wheels 542 adapted to the shape of the flexible element 541 may be disposed on the frame 120, for example, the idle wheels 542 may be smooth wheels capable of guiding the steel wire rope or the belt, or a timing pulley capable of guiding the timing belt, or a sprocket capable of guiding the chain, etc.

Therefore, the transit part 540 can arrange the track of the flexible member 541 according to the specific structure of the frame 120, and prevent the installation space of the transit part 540 and the frame 120 from interfering, for example, when the frame 120 is a welded frame 120, the idle wheels 542 can be installed on the frame 120 by welding, so that the flexible member 541 can be easily guided from the upper part of the frame 120 to the lower part of the frame 120, and the scram 520 and the sensing part 530 can be connected.

Further, it is contemplated that the crash stop 520 and the sensing part 530 may be connected to the flexible member 541 in any manner as long as they are adapted to the flexible member 541, for example, the crash stop 520 and the sensing part 530 may be connected to the flexible member 541 through a connection part 543, respectively, and the connection part 543 may be, for example, a chuck for clamping a wire rope, a belt, or a timing belt, or a pin for connecting a chain, etc. In addition, the flexible member 541 can be directly connected to the emergency stop 520 and the sensing part 530 by various methods such as winding, screwing, riveting, welding, clamping, etc.

Although the flexible piece 541 is described as the relay unit 540, the present invention is not limited thereto, and the relay unit 540 may be connected to the scram 520 and the sensor unit 530 by another connection method, such as a link (not shown).

Referring to fig. 18 and 19, the sensing portion 530 of fig. 18 and the sensing portion 530 of fig. 19 are substantially the same except for the different directions, and therefore, will be described in conjunction therewith. Referring to fig. 18 and 19, with additional reference to fig. 14, in some embodiments, to easily control the sensing part 530, to prevent the sensor 210 from missensing the sensing part 530 when the carrying device 200 carries the rack 120, the sensing part 530 includes a sensing piece 531 and a shutter piece 532, and the shutter piece 532 and at least one of the sensing piece 531 are connected to the scram 520 and are driven as the scram 520 is switched between the operating position 501 and the stopping position 502, such that the shutter piece 532 shields the sensing piece 531, or the sensing piece 531 is exposed with respect to the shutter piece 532. Specifically, the sensing member 531 is fixed on the frame 120, and the shielding member 532 is connected to the other end 541b of the flexible member 541, and is pulled by the flexible member 541 and switches the position relative to the sensing member 531 as the scram 520 switches between the operating position 501 and the stopping position 502, so that the sensing member 531 is exposed or shields the sensing member 531. The shield 532 has a plate shape, the frame 120 is further provided with a sliding groove 533 at a lower portion of the sensing member 531, and at least an edge portion of the shield 532 is inserted into the sliding groove 533 and can slide in the sliding groove 533. The shield 532 is connected by a clamp as a connection portion 543 and a wire rope as a flexible member 541, for example, and thereby connected to the scram 520 provided at the upper portion of the housing 120. When the scram 520 is switched between the operating position 501 and the stop position 502, the wire rope as the flexible member 541 is pulled, thereby causing the shutter 532 to slide in the slide groove 533, for example, to move in the front-rear direction in the drawing, thereby shielding the sensor 531 or exposing the sensor 531. When the sensing part 530 is exposed, it can be sensed by the sensor 210 of the carrying device 200, so that the sensor 210 can input a signal (e.g., an ON control signal) for continuing the operation to the carrying device 200. When the sensing piece 531 is shielded by the shielding piece 532, the sensor 210 cannot sense the sensing piece 531, and the sensor 210 can input a signal of an emergency stop (e.g., an OFF control signal) to the handling device 200. Accordingly, the conveyance device 200 can determine the operation (continuous operation) or emergency stop according to whether the control signal is input from the sensor 210.

Therefore, the vehicle 100 of the present invention can easily control the conveyance device 200 to stop or continue the operation by the mechanical scram device 500. Further, the sudden stop device 500 can be easily installed to any position of the frame 120 through the transit part 540, and thus the sudden stop device 500 can be installed according to an operation position suitable for an operator.

It is conceivable that, although the example in which the scram 520 is connected to the shutter 532 via the flexible member 541 and the shutter 532 is driven to slide in the sliding groove 533 has been described, the invention is not limited thereto, and for example, the scram 520 may be connected to the sensor 531 via the flexible member 541, the shutter 532 may be attached to the lower portion of the housing 120, the sliding groove 533 may be disposed on the upper portion of the shutter 532, and the scram 520 may pull the sensor 531 via the flexible member 541 so that the sensor 531 is exposed with respect to the shutter 532 or is shielded by the shutter 532.

In addition, in order to save the driving stroke of the scram 520, the shutter 532 and the sensor 531 may be slidably provided, and the shutter 532 and the sensor 531 may be connected by a transmission mechanism such as a rack and pinion, and may be interlocked therewith. Alternatively, the crash stop 520 may be connected to both the blocking member 532 and the sensing member 531, for example, the crash stop 520 is connected to two flexible members 541, and the two flexible members 541 are connected to the blocking member 532 and the sensing member 531, respectively, and are guided by different idler pulleys 542 for rotation so that the sliding directions thereof are opposite.

In some embodiments, a resilient drive member 550 is further included, the resilient drive member 550 being configured to drive the shutter 532 or the sense member 531 such that the shutter 532 shields the sense member 531 or the sense member 531 is exposed from the shutter 532 when the crash stop 520 is switched from the run position 501 to the stop position 502. The following are: a position where the sensing portion 530 can be sensed by the sensor 210 of the conveying apparatus 200 by the scram 520 is described as the operation position 501, and a position where the sensing portion 530 is disconnected from the sensor 210 of the conveying apparatus 200 by the scram 520 is described as the stop position 502. In the present embodiment, the flexible member 541 and the shade 532 are connected to each other as an example. Specifically, in the present embodiment, one end of the elastic driving member 550 abuts against the frame 120, and one end abuts against the shielding member 532, for example, for convenience of abutting the elastic driving member 550 against the shielding member 532, a protruding sheet metal member 534 may be provided on the shielding member 532, and for attaching the elastic driving member 550, an attaching shaft 535 may be provided. When the scram 520 is in the operating position 501, the scram 520 drives the shutter 532 by pulling the flexible member 541, and at the same time, the elastic driving member 550 is compressed, so that the sensing member 531 is exposed from the shutter 532, and the sensing member 531 can be sensed by the sensor 210 of the carrying device 200. When the scram 520 is switched from the operating position 501 to the stopping position 502 (i.e., when the scram 520 is switched to the position in the direction of releasing the flexible member 541), the compression of the elastic driving member 550 is released, and thereby the elastic driving member 550 drives the shutter 532 to slide in the sliding groove 533 (in the front direction in fig. 18) and covers the sensing member 531, and the sensing member 531 is disconnected with respect to the sensing member 531 of the carrying device 200. By providing the elastic driving member 550, it is possible to reliably shield the sensor member 531 from the shutter member 532 or to expose the sensor member 531 from the shutter member 532, thereby improving the reliability of the operation or stop of the carrying device 200.

It is contemplated that the elastic driving member 550 may be an outwardly expanding type elastic member such as a coil spring, a nitrogen spring, a hydraulic buffer, or the like, or an inwardly contracting type elastic member such as a tension spring, an elastic belt, or the like. Those skilled in the art can appropriately change the mutual positions of the elastic driving member 550 and the flexible member 541 according to the actual installation space.

It is understood that although the above description has been given by taking the elastic driving member 550 as an example to drive the shutter 532, the invention is not limited thereto, and for example, the elastic driving member 550 may drive the sensing member 531 so that the shutter 532 shields the sensing member 531 or the sensing member 531 is exposed from the shutter 532.

In addition, although the sensing part 530 has the shielding member 532 and the sensing member 531 as an example, the invention is not limited thereto, and in some embodiments, for example, the sensing part 530 may include only the sensing member 531, and the sensing member 531 may be connected to the crash stop 520 and sensed by the sensor 210 or disconnected with respect to the sensor 210 as the crash stop 520 switches between the operating position 501 and the stopping position 502.

In some embodiments, in order to facilitate the operator to control the stopping or starting of the handling device 200 from various directions, the crash stops 520 include a plurality of positions, and the shutters 532 include a plurality of positions, and each of the crash stops 520 is respectively connected to the shutters 532 and respectively drives the shutters 532 so that the shutters 532 block the sensing members 531 or the sensing members 531 are exposed relative to the shutters 532. Specifically, for example, one mounting seat 510 may be respectively installed in the front-rear direction of the rack 120, one scram 520 may be respectively installed in each mounting seat 510, and correspondingly, the sensing part 530 includes one sensing piece 531 and two shielding pieces 532, and the scrams 520 located in the front-rear direction of the rack 120 are respectively connected to the two shielding pieces 532, so that the shielding pieces 532 can be independently driven to shield the sensing piece 531 or expose the sensing piece 531 relative to the shielding pieces 532. Thus, in the present embodiment, the operator can easily operate the crash stops 520 at various positions, and the safety of the conveying apparatus 200 can be improved. In addition, since the sensing member 531 is fixed to the frame 120, there is no need to adjust the position of the sensor 210 with respect to the sensing member 531, and there is no need to increase the number of the sensors 210, which not only facilitates the control of the operation or stop of the carrying device 200, but also does not require an additional increase in cost.

With continuing reference to fig. 15 and 16 and with additional reference to fig. 14 and 17, the scram 520 will be described in detail below.

As described above, the operating position 501 and the stopping position 502 may be any positions as long as the position of the sensing part 530 can be changed. It is contemplated that hard stop 520 may be switched from operating position 501 to stopping position 502 by, for example, sliding, swinging, or pivoting. For example, the hard stops 520 may be slidably mounted to the mount 510 to slidably switch from the run position 501 to the stop position 502; alternatively, the hard stop 520 may be mounted to the mount 510, for example, by a hinged connection, to swing from the run position 501 to the stop position 502; or the scram 520 can be arranged to rotate around the axis of the scram relative to the mounting seat 510 so as to be switched from the running position 501 to the stopping position 502; or the hard stop 520 and mount 510 may be integrally assembled in the form of a manual quick clamp.

In some embodiments, in order to stably maintain the scram 520 in the operating position 501 or the stopping position 502, the scram device 500 may further include an elastic restriction member 560, and the elastic restriction member 560 is configured to restrict the scram 520 when the scram 520 is located in the operating position 501 or the stopping position 502. Specifically, the elastic restriction member 560 may be selected from elastic restriction members 560 such as an elastic pin, a roller plunger, and a ball plunger. In addition, the elastic restriction member 560 may be installed on either the mount 510 or the hard stop 520.

For example, to facilitate installation of the elastic restriction member 560, in some embodiments, the elastic restriction member 560 is installed to the installation seat 510, the scram 520 is provided with a first slot portion 521 and a second slot portion 522 at intervals in the switching direction, and the elastic restriction member 560 is inserted into the first slot portion 521 when the scram 520 is located at the operation position 501; when the scram 520 is located at the stop position 502, the elastic restriction member 560 is inserted into the second groove portion 522. Thus, the installation of the elastic stoppers 560 can be facilitated while stably holding the hard stops 520.

In some embodiments, to facilitate the switching of the hard stops 520, the mounting seat 510 is provided with a guide portion 511, and the hard stops 520 are slidably mounted in the guide portion 511. Specifically, for example, the guide portion 511 may be provided with a guide hole 512, and in correspondence with this, the crash stop 520 is provided in a substantially shaft shape, the first groove portion 521 and the second groove portion 522 are respectively provided at intervals in the axial direction of the crash stop 520, the crash stop 520 slides within the guide hole 512 of the mount 510, and the elastic restriction member 560 is mounted to the mount 510 and partially protrudes into the guide hole 512 in the radial direction of the guide hole 512, being inserted into the first groove portion 521 or the second groove portion 522. Thereby, the scram 520 can be switched between the running position 501 and the stopping position 502 in a sliding manner.

Further, although the description has been made with an example in which the scram 520 is restricted by the elastic restricting member 560, it is not limited thereto, and for example, the scram 520 may be stabilized in the running position or the stopping position by means of a link (for example, when the scram 520 and the mount 510 are assembled in the form of a manual quick clamp).

Therefore, since the scram device 500 as described above is provided with the sensing part 530 that can be sensed by the sensor 210 of the transport device 200 that transports the carrier 100 or is disconnected from the sensor 210 in accordance with the switching of the scram 520, the carrier 100 can easily control the operation or stop of the transport device 200 without a control system.

In addition, since the scram 520 is connected with the sensing part 530 through the transferring part 540, such as the flexible part 541, the scram 520 can be disposed at any position convenient for the operator to operate, thereby improving the safety of the transportation device 200.

Further, since the scram 520 can be disposed at a plurality of positions corresponding to the sensing members 531, it is not only easy to control the operation or stop of the conveying apparatus 200, but also it is not necessary to increase the cost.

Further, since the elastic restricting member 560 is further provided, the scram 520 can be stably held at the operation position 501 or the stop position 502, and the reliability of the operation or the stop (continuation of the operation) of the conveyance device 200 can be improved.

As the sensing portion 530 sensed by the sensor 210, for example, the sensing element 531 of the sensing portion 530 may be a sensing element in a sheet shape or a strip shape, and correspondingly, the sensor 210 may be a sensor such as a photoelectric sensor, an ultrasonic sensor, a laser obstacle avoidance sensor, or a proximity switch, or may be a sensor having a camera such as a smart camera, a CCD, a code scanning gun, or a code scanning box. Further, the sensor 210 may be a travel switch or the like.

In some embodiments, in order to improve the accuracy of sensing, the sensor 210 may select the sensor 210 having a camera, and the sensing part 530 is provided with an identification part (not shown) that can be identified by the camera. Specifically, for example, the sensor 210 may be a code scanning gun or a code scanning cassette mounted to the AGV car as the transport device 200, and correspondingly, the recognition portion of the sensing portion 530 may be a two-dimensional code disposed at a lower portion of the sensing member 531, thereby improving the accuracy of sensing and improving the reliability of the scram device 500 in controlling the operation or stop of the transport device 200.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
