Description

Technical Field

[0001] The present invention relates to the technical field of warehouse cargo transportation, in particular to a warehouse cargo transportation device. Background Art

[0002] With the development of the domestic economy, especially the rapid development of manufacturing enterprises, more and more production needs to sort and transport a large amount of stored goods. The goods that need to be shipped out every day are large and diverse. Conveying equipment is especially important for manufacturing companies that produce fragile items. Moving the goods out of the warehouse on the conveying equipment can effectively avoid bumps and breakages of products during transportation.

[0003] Considering that the equipment may need to be shut down during operation, since the existing transmission unit is usually directly connected to the drive motor, it will stop instantly when the drive motor loses power, and the transmission unit will also stop. When transporting items, it may cause the items to fall due to inertia. When the items being transported are fragile items, they may fall and break, causing property loss. At the same time, power outages and other situations may also cause items to fall. Summary of the Invention

[0004] The object of the present invention is to provide a warehouse cargo conveying device to solve the problems raised in the above background technology.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a warehouse cargo conveying device, comprising a transmission unit, the transmission unit comprising a transmission belt, baffles fixedly connected to both sides of the transmission belt, a plurality of rotating shafts meshing with the inner surface of the transmission belt; the rotating shafts all pass through the baffles and are rotatably connected to the baffles; an isolation cover fixedly connected to one side of the baffle, a bracket fixedly connected to the bottom of the baffle and the isolation cover; the bracket is used to support the device; one side of the transmission belt is a feed port, and the other side is a discharge port;

[0007] The rotating shaft on the side close to the feeding port is the driving shaft, and the driving shaft is fixedly connected to the driving unit; the rotating shaft adjacent to the driving shaft is the slow-stop shaft, and the slow-stop shaft is slidably connected to the slow-stop unit; the rotating shaft close to the discharging port is the buffer shaft, and the buffer shaft is fixedly connected to the buffer unit; the driving unit and the slow-stop unit are both located inside the isolation cover, and the driving unit and the slow-stop unit are connected via a transmission unit;

[0008] The driving unit includes a motor frame, a driving motor and a locking unit, the motor frame is fixedly connected to the baffle, the motor frame is slidably connected to the driving motor, and a sliding hole is provided on the surface of the motor frame; the driving motor is fixedly connected to a hinge shaft on the side close to the motor frame, the hinge shaft is slidably connected to the sliding hole, and the hinge shaft is hinged to the transmission unit; a first spring is fixedly connected between the side of the driving motor away from the motor frame and the baffle, an electromagnet is provided at the output end of the driving motor, and the output shaft of the driving motor is slidably connected to the locking unit; the locking unit is fixedly connected to the driving shaft on the side away from the driving motor, and the locking unit is made of iron; the locking unit is used to lock with the output shaft of the driving motor for synchronous rotation.

[0009] With the above technical solution, when the device is operating normally, the magnetism between the electromagnet at the output end of the drive motor and the locking unit can attract each other. Since the locking unit is fixed to the drive shaft, only the drive motor will move. When the drive motor moves, it compresses the first spring. When the drive motor and the locking unit are locked, the drive motor can drive the transmission unit to transport the object.

[0010] When the present invention is shut down in a non-emergency situation or encounters a power outage, the drive motor will shut down due to power loss, and the electromagnet will lose its lock with the locking unit. The first spring will push the drive motor to disengage from the locking unit, and the transmission unit will be pushed to move while the hinge shaft moves. Since the transmission unit is not directly connected to the drive motor, the drive motor will not directly stop the transmission unit after the equipment is powered off, but will cause the transmission unit to continue to transmit according to inertia, so as to prevent the objects on the transmission unit from falling over due to inertia caused by the momentary stop, thereby avoiding damage to the objects caused by falling over.

[0011] Furthermore, the transmission unit includes a support frame and a connecting rod, the support frame is fixedly connected to the baffle, the support frame is hinged to the connecting rod, and the hinge point between the support frame and the connecting rod is away from the center of the connecting rod and close to the driving unit; the connecting rod is hinged to the hinge shaft of the driving motor;

[0012] The slow-stop unit includes a hinge block, which is hinged to the end of the connecting rod away from the hinge shaft, and the bottom of the hinge block is fixedly connected to a connecting block; a connecting hole is provided on the surface of the baffle, and the connecting block is slidably connected in the connecting hole. The length of the connecting hole is longer than the connecting block and serves as a redundant space for the connection block to be moved. A pressure hole is provided on the side of the connecting block close to the slow-stop shaft; a pressure unit is slidably connected in the pressure hole.

[0013] By adopting the above technical solution, since the hinge between the support frame and the connecting rod is closer to the driving unit, when the driving unit pushes the connecting rod, only a short stroke is needed to make the slow-stop unit move a larger stroke; when the connecting rod pushes the hinge block and the connecting block to move, the pressing unit will come into contact with the slow-stop shaft, and the equipment will be slowly stopped by friction; the transmission unit can be slowly stopped by stopping by friction, which can avoid the dumping of objects caused by rapid shutdown, and at the same time avoid the inertia of the transmission belt from impacting the stopped rotating shaft during emergency stop, thereby increasing the service life.

[0014] Furthermore, the pressing unit includes a pressing block, which is slidingly connected to the pressing hole, and a third spring is fixedly connected between the pressing block and the pressing hole. A rotation groove is provided on the side of the pressing block away from the third spring; a damping wheel is rotatably connected in the rotation groove, and the damping wheel is hollow and made of flexible material.

[0015] By adopting the above technical solution, when the connecting block moves, the pressure block will be driven to move as well. Through the setting of the damping wheel, the force of the third spring to reset the pressure block and the distance the connecting block moves are used to make the damping wheel generate pressure on the slow-stop shaft during use. At the same time, through contact, the damping wheel generates resistance in the rotation direction of the slow-stop shaft, but the generated resistance will not cause the slow-stop shaft to stop directly, so that the slow-stop shaft will stop slowly. When in use, the friction between the pressing unit and the slow-stop shaft can be converted into rotational friction, thereby reducing the wear caused by friction when in contact with the slow-stop shaft.

[0016] Furthermore, an extension plate is fixedly connected to the top of the hinge block, a hydraulic rod is fixedly connected to the bottom of one side of the extension plate, and the hydraulic rod is slidably connected to the buffer unit;

[0017] The gear train is connected with the gear shift lever, and the gear train is connected with the gear shift lever, and the gear train is connected with the gear shift lever on the left side of the gear shift lever.

[0018] With the above technical solution, when the equipment slowly stops, the hydraulic rod moves toward the inside of the hydraulic box by pressing down the hinge block, and the first gear is pushed to move by the hydraulic pipe. Since the connecting shaft is connected to the buffer shaft, the first gear generates power, and through engagement with the second gear, the second gear drives the connecting plate to rotate about the connecting rod as the axis, so that the connecting plate is lifted to prevent the objects on the transmission unit from continuing to move. At this time, the connecting plate is lifted by the remaining power of the buffer shaft, thereby achieving the goal of still being lifted even in a power outage and protecting the objects from falling or leaving the transmission unit.

[0019] When the lifting angle of the connecting plate is perpendicular to the transmission unit, the subsequent objects may collide with the objects in front and the force cannot be unloaded, causing fragile objects to be broken by the impact; since the transmission unit will be slowly stopped by the friction of the slow-stop unit, the angle at which the connecting plate can be lifted will not be perpendicular to the transmission unit, thereby causing the connecting plate to tilt outward. When the transmission unit slowly stops, some objects will slide onto the connecting plate due to inertia, but due to the inclination of the connecting plate, when subsequent objects collide, the objects in front can move toward the connecting plate to unload the force, and the inclined connecting plate can make the objects retreat under gravity, so that they will not stay on the connecting plate for a long time; at the same time, since the transmission unit is already in a slowly stopped state, the impact of subsequent objects will also be reduced;

[0020] During normal use, the first gear is not connected to the connecting shaft and the second gear. At this time, the connecting plate will rotate downward under the influence of gravity. At this time, the connecting plate can be placed on the subsequent device to transfer items to the subsequent device.

[0021] Furthermore, the locking unit includes a locking shell, which is fixedly connected to the drive shaft on the side away from the drive motor, and a locking hole is provided on the inner wall of the locking shell. A locking block is slidably connected to the inner wall of the locking hole, and the locking block is connected to the locking hole by a second spring; the locking block and the locking shell are both made of iron; two clamping blocks are fixedly connected to the side of the electromagnet close to the locking unit, and the clamping blocks are in contact with the locking block.

[0022] With the above technical solution, the arrangement of the clamping block and the locking block allows the locking block to be sucked outward when the electromagnet is energized. The contact between the clamping block and the locking block causes the output shaft of the drive motor to rotate when it rotates, thereby causing the drive shaft to rotate, thereby driving the transmission unit to operate.

[0023] When the device is powered off, the attraction of the electromagnet will disappear instantly. At this time, the locking block and the locking housing will lose the magnetic attraction of the electromagnet. The locking block will reset under the traction of the second spring. At the same time, the drive motor will also reset under the force of the first spring, thereby allowing the drive motor to detach from the locking housing.

[0024] Furthermore, a buffer plate is provided on the side of the extension plate away from the hydraulic rod, the buffer plate and the extension plate are connected by a fourth spring, and a buffer plate is slidably connected to the inner wall of the sliding groove away from the hydraulic box, and the buffer plate is in contact with the baffle.

[0025] By adopting the above technical solution, when the hinge block and the connecting block move, the buffer plate is always in direct contact with the baffle, and the setting of the fourth spring can enable the buffer plate to accumulate force due to the shortening of the distance between the buffer plate and the baffle. During the force accumulation process, the force of the driving unit on the transmission unit can be slowed down, thereby avoiding the pressure block from contacting the slow-stop shaft too quickly, and preventing the slow-stop shaft from being subjected to a large force and stopping quickly.

[0026] Furthermore, a tensioning unit is fixedly connected between the baffles, and the tensioning unit includes a fixing frame, both ends of the fixing frame are fixedly connected to the baffles, a plurality of tensioning holes are opened at the bottom of the baffle, the inner wall of the tensioning hole is slidably connected with the tensioning frame, the tensioning frame and the tensioning hole are connected by a fifth spring, and the tensioning frame is rotatably connected to the inner wall near the bottom with a tensioning wheel, and the tensioning wheel is rotatably connected to the transmission belt.

[0027] By adopting the above technical solution, in order to prevent the breakage, the transmission belt can use a longer redundancy, and the tension of the transmission belt is maintained by the tensioning unit. Under normal circumstances, the fifth spring will push the tensioning frame, so that the tensioning wheel contacts the transmission belt, and thereby tighten the redundancy of the transmission belt; when encountering heavier objects and the transmission belt is stretched, the transmission belt in contact with the tensioning wheel will be pulled, and the tensioning wheel will move upward. At this time, the tensioning frame will compress the fifth spring and keep the transmission belt in the appropriate tension range.

[0028] Furthermore, a pneumatic housing is fixed to the side of the connecting block away from the pressure block, and a pneumatic hole is opened on the same side of the connecting block; a pneumatic plate is slidably connected to the inner wall of the pneumatic housing, and the side of the pneumatic housing away from the connecting block is fixedly connected to the isolation cover through a pneumatic tube, and an emergency stop button is slidably connected to the end of the pneumatic tube away from the pneumatic housing; the emergency stop button is used to urgently stop the equipment, and the emergency stop button is electrically connected to the power supply of the equipment.

[0029] By adopting the above technical solution, when a person is caught in the transmission belt, the power of the equipment can be cut off by pressing the emergency stop button. At the same time, the air inside the pneumatic tube will be pushed, and the airflow will be introduced into the starting shell to push the pneumatic plate to move. At this time, the pneumatic plate will push the air from the pneumatic hole to the pressure hole. Since the air pressure in the pressure hole increases, it will continue to push the pressure block outward and make the pressure block unable to reset, thereby making the equipment shut down quickly, thereby achieving the effect of emergency stop.

[0030] The present invention has the following beneficial effects:

[0031] 1. When the present invention is shut down in a non-emergency situation or encounters a power outage, the drive motor will shut down due to power loss, and the electromagnet will lose its lock with the locking unit. The first spring will push the drive motor out of the locking unit, and the transmission unit will be pushed to move while the hinge shaft moves. Since the transmission unit is not directly connected to the drive motor, the drive motor will not directly stop the transmission unit after the power is cut off, but will cause the transmission unit to continue to transmit according to inertia, so as to prevent the objects on the transmission unit from falling due to inertia caused by the momentary stop, thereby avoiding damage to the objects caused by falling.

[0032] 2. In the present invention, since the hinge between the support frame and the connecting rod is closer to the driving unit, when the driving unit pushes the connecting rod, only a short stroke is needed to make the slow-stop unit move a larger stroke; when the connecting rod pushes the hinge block and the connecting block to move, the pressing unit will come into contact with the slow-stop shaft, and the equipment will be slowly stopped by friction; the transmission unit can be slowly stopped by stopping by friction, which can avoid the dumping of objects caused by rapid shutdown, and at the same time avoid the inertia of the transmission belt from impacting the stopped rotating shaft during emergency stop, thereby increasing the service life.

[0033] 3. The present invention moves the hydraulic rod toward the inside of the hydraulic box by pressing down the hinge block, and pushes the first gear to move through the hydraulic pipe. Since the connecting shaft is connected to the buffer shaft, the first gear will generate power, and through engagement with the second gear, the second gear drives the connecting plate to rotate with the connecting rod as the axis, so that the connecting plate is lifted to prevent the objects on the transmission unit from continuing to move. At this time, the connecting plate is lifted by the remaining power of the buffer shaft, thereby achieving the goal of still being able to lift even when the power is off, and protecting the objects from falling or leaving the transmission unit.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] See also Figures 1-10As shown, the present invention is a warehouse cargo conveying equipment, including a transmission unit 1, which includes a transmission belt 11. Both sides of the transmission belt 11 are fixedly connected to baffles 12. The inner surface of the transmission belt 11 is engaged with multiple rotating shafts 13; the rotating shafts 13 all pass through the baffles 12 and are rotatably connected to the baffles 12; one side of the baffle 12 is fixedly connected to an isolation cover 14, and the bottom of the baffle 12 and the isolation cover 14 are fixedly connected to a bracket 17; the bracket 17 is used to support the equipment; one side of the transmission belt 11 is a feed port, and the other side is a discharge port;

[0049] The rotating shaft 13 on the side close to the feeding port is the driving shaft, which is fixedly connected to the driving unit 2; the rotating shaft 13 adjacent to the driving shaft is the slow-stop shaft, which is slidably connected to the slow-stop unit 3; the rotating shaft 13 close to the discharging port is the buffer shaft, which is fixedly connected to the buffer unit 4; the driving unit 2 and the slow-stop unit 3 are both located inside the isolation cover 14, and the driving unit 2 and the slow-stop unit 3 are connected via the transmission unit 5;

[0050] The driving unit 2 includes a motor frame 21, a driving motor 22 and a locking unit 7. The motor frame 21 is fixedly connected to the baffle 12, and the motor frame 21 is slidably connected to the driving motor 22. A sliding hole is provided on the surface of the motor frame 21; the driving motor 22 is fixedly connected to a hinge shaft on the side close to the motor frame 21, the hinge shaft is slidably connected to the sliding hole, and the hinge shaft is hinged to the transmission unit 5; a first spring 24 is fixedly connected between the side of the driving motor 22 away from the motor frame 21 and the baffle 12, and an electromagnet is provided at the output end of the driving motor 22, and the output shaft of the driving motor 22 is slidably connected to the locking unit 7; the locking unit 7 is fixedly connected to the driving shaft on the side away from the driving motor 22, and the locking unit 7 is made of iron; the locking unit 7 is used to lock with the output shaft of the driving motor 22 for synchronous rotation.

[0051] In this embodiment, it is considered that the equipment may need to be shut down during operation. Since the existing transmission unit 1 is usually directly connected to the drive motor 22, the drive motor 22 will stop instantly when it loses power, and the transmission unit 1 will also stop. When conveying items, the items may fall due to inertia. If the conveyed items are fragile items, the fragile items may fall and break, causing property loss. At the same time, the items may fall when encountering power outages and tripping.

[0052] During normal operation of the device, the magnetism between the electromagnet at the output end of the drive motor 22 and the locking unit 7 can attract each other. Since the locking unit 7 is fixed to the drive shaft, only the drive motor 22 moves. When the drive motor 22 moves, it compresses the first spring 24. When the drive motor 22 and the locking unit 7 are locked, the drive motor 22 can drive the transmission unit 1 to transport the object.

[0053] When the machine is shut down in a non-emergency situation or encounters a power outage, the drive motor 22 will stop due to power loss. At the same time, the electromagnet will lose power and will lose its lock with the locking unit 7. At the same time, under the action of the first spring 24, the drive motor 22 will completely disengage from the locking unit 7, and the drive motor 22 will slide on the motor frame 21 through the hinge shaft. When the hinge shaft moves, it will push the transmission unit 5 to move.

[0054] Through the above method, the transmission unit 1 is not directly connected to the drive motor 22. After the power is cut off, the drive motor 22 will not directly stop the transmission unit 1, but will cause the transmission unit 1 to continue to transmit according to inertia, so as to prevent the objects on the transmission unit 1 from falling due to inertia caused by the momentary stop, thereby avoiding damage to the objects caused by falling.

[0055] Specifically, the transmission unit 5 includes a support frame 51 and a connecting rod 52. The support frame 51 is fixedly connected to the baffle 12. The support frame 51 and the connecting rod 52 are hinged. The hinge point between the support frame 51 and the connecting rod 52 is away from the center of the connecting rod 52 and close to the drive unit 2. The connecting rod 52 is hinged to the hinge shaft of the drive motor 22.

[0056] The slow-stop unit 3 includes a hinge block 31, which is hinged to the end of the connecting rod 52 away from the hinge axis, and the bottom of the hinge block 31 is fixedly connected to the connecting block 32; a connecting hole is provided on the surface of the baffle 12, and the connecting hole is slidingly connected to the connecting block 32. The length of the connecting hole is longer than the connecting block 32, and serves as a redundant space for the connection block 32 to be moved. A pressure hole is provided on the side of the connecting block 32 close to the slow-stop axis; the pressure unit 8 is slidingly connected in the pressure hole.

[0057] In this embodiment, considering that the transmission unit 1 will continue to transmit due to inertia after power failure, if the rear end of the transmission unit 1 is blocked, objects may collide with each other due to the blockage, which may cause damage to the objects or they may be thrown out of the device due to excessive inertia.

[0058] When the driving unit 2 pushes the transmission unit 5 to move due to a shutdown, since the hinge between the support frame 51 and the connecting rod 52 is closer to the driving unit 2, when the driving unit 2 pushes the connecting rod 52, only a short stroke is required to make the slow-stop unit 3 move a longer stroke.

[0059] When the connecting rod 52 pushes the hinge block 31 to move, it also pushes the connecting block 32 to move. Since the connecting rod 52 rotates in an arc when pushing the hinge block 31 to move, the hinge block 31 and the connecting block 32 will follow the arc rotation and make the connecting block 32 closer to the slow-stop shaft, so that the pressing unit 8 contacts the slow-stop shaft and the device is slowly stopped by friction.

[0060] Through the above operation, the drive unit 2 can cause the transmission unit 1 to stop slowly by friction after stopping. The transmission unit 1 can be stopped slowly by stopping by friction, which can avoid the objects from falling due to rapid stopping. At the same time, it can avoid the inertia of the transmission belt 11 from impacting the stopped slow-stop shaft during emergency stopping, thereby increasing the service life.

[0061] Specifically, the pressing unit 8 includes a pressing block 33, which is slidingly connected to the pressing hole. A third spring 35 is fixedly connected between the pressing block 33 and the pressing hole. A rotating groove is provided on the side of the pressing block 33 away from the third spring 35; a damping wheel 34 is rotatably connected in the rotating groove, and the damping wheel 34 is hollow and made of flexible material.

[0062] In this embodiment, it is considered that friction between the pressing unit 8 and the slow-stop shaft will cause loss. After long-term use, the contact area may become smaller or even lose contact due to friction, resulting in the inability to stop the transmission unit 1 by friction. At the same time, the loss caused by friction will also reduce the service life of the device.

[0063] When the connecting block 32 moves, it drives the pressing block 33 to move. Through the setting of the damping wheel 34, during use, the force of the third spring 35 to reset the pressing block 33 and the distance moved by the connecting block 32 are used to make the damping wheel 34 produce pressure on the slow-stop shaft. At the same time, through contact, the damping wheel 34 produces resistance in the rotation direction of the slow-stop shaft. However, the resistance produced will not stop the slow-stop shaft directly, so that the slow-stop shaft will stop slowly. When in use, the friction between the pressing unit 8 and the slow-stop shaft can be converted into rotational friction, thereby reducing the wear caused by friction when in contact with the slow-stop shaft.

[0064] Since the damping wheel 34 is hollow and made of flexible material, it is filled with air when in use. When the impact force with the slow-stop shaft is large, the internal air can be used for buffering. When the pressure is large, the slow-stop shaft can push the air inside the damping wheel 34 and make the slow-stop shaft directly contact with the pressure block 33, thereby obtaining a larger contact area and a faster braking speed.

[0065] Specifically, the top of the hinge block 31 is fixedly connected to an extension plate 312, and the bottom of one side of the extension plate 312 is fixedly connected to a hydraulic rod, which is slidably connected to the buffer unit 4;

[0066] The buffer unit 4 includes a connecting plate 18, which is located at the discharge port of the transmission belt 11. Both sides of the bottom of the connecting plate 18 are hinged to the baffle 12, and one side of the connecting plate 18 is fixedly connected to a connecting rod; the connecting rod passes through the baffle 12 and is rotatably connected to the baffle 12, and the end of the connecting rod away from the connecting plate 18 is fixedly connected to the second gear 45; the left side of the second gear 45 is meshed with the first gear 44; the side of the first gear 44 away from the baffle 12 is fixedly connected to the hydraulic column, and the side of the first gear 44 close to the baffle 12 is clamped with a connecting rod. The connecting shaft 46 is fixedly connected to the buffer shaft, and the length of the connecting shaft 46 is half the thickness of the second gear 45; the outer wall of the hydraulic column is slidably connected to the hydraulic gear rack 43; the hydraulic gear rack 43 is connected to the hydraulic box 41 through the hydraulic pipe 42; sliding grooves are provided on both sides of the end of the connecting block 32 close to the hinge block 31, and the inner wall of the sliding groove close to the hydraulic box 41 is slidably connected to the hydraulic box 41; the inner wall of the hydraulic box 41 is slidably connected to the hydraulic rod, and the side of the hydraulic box 41 close to the baffle 12 is slidably connected to the baffle 12.

[0067] In this embodiment, considering that the subsequent equipment may have problems when the equipment is actively stopped, the items on the transmission unit 1 may still be transferred to the subsequent equipment when the transmission unit 1 slowly stops;

[0068] While the equipment slowly stops, the hydraulic rod moves toward the inside of the hydraulic box 41 through the downward pressure of the hinge block 31, and the hydraulic power is transmitted to the hydraulic gear rack 43 through the hydraulic pipe 42, and the first gear 44 is pushed to move. Since the height of the connecting shaft 46 is half of the second gear 45, when the first gear 44 moves, it will first mesh with the second gear 45 and then engage with the connecting shaft 46. At this time, the connection between the connecting shaft 46 and the buffer shaft will generate power for the first gear 44, and through the meshing with the second gear 45, the second gear 45 drives the connecting plate 18 to rotate with the connecting rod as the axis, so that the connecting plate 18 is lifted to prevent the objects on the transmission unit 1 from continuing to move. At this time, the connecting plate 18 is lifted by the remaining power of the buffer shaft, thereby achieving the goal of still being able to lift even when the power is off and protecting the objects from falling. When the lifting angle of the connecting plate 18 is perpendicular to the transmission unit 1, the subsequent objects may collide with the objects in front and the force cannot be unloaded, causing fragile objects to be broken by the impact. Since the transmission unit 1 is slowly stopped by the friction of the slow-stop unit 3, the angle at which the connecting plate 18 can be lifted will not be perpendicular to the transmission unit 1, thereby making the connecting plate 18 tilt outward. When the transmission unit 1 slowly stops, some objects will slide onto the connecting plate 18 due to inertia. However, due to the inclination of the connecting plate 18, when subsequent objects collide, the objects in front can move onto the connecting plate 18 to unload the force, and the tilted connecting plate 18 can make the objects retreat under gravity, so that they will not stay on the connecting plate 18 for a long time. At the same time, since the transmission unit 1 is already in a slowly stopped state, the impact of subsequent objects will also be reduced.

[0069] During normal use, the first gear 44 is not connected to the connecting shaft 46 and the second gear 45. At this time, the connecting plate 18 will rotate downward under the influence of gravity. At this time, the connecting plate 18 can be placed on the subsequent device, thereby transferring items to the subsequent device.

[0070] Specifically, the locking unit 7 includes a locking shell 23, which is fixedly connected to the drive shaft on the side away from the drive motor 22. A locking hole is provided on the inner wall of the locking shell 23, and a locking block 26 is slidably connected to the inner wall of the locking hole. The locking block 26 is connected to the locking hole by a second spring 25; the locking block 26 and the locking shell 23 are both made of iron; two clamping blocks are fixedly connected to the side of the electromagnet close to the locking unit 7, and the clamping blocks are in contact with the locking block 26.

[0071] In this embodiment, it is considered that the magnetic attraction of the electromagnet may not be able to rotate normally due to insufficient magnetic attraction when encountering a heavy object; the arrangement of the clamping block and the locking block 26 can suck the locking block 26 outward when the electromagnet is energized. Through the contact between the clamping block and the locking block 26, the output shaft of the drive motor 22 drives the locking housing 23 to rotate when rotating, thereby rotating the drive shaft, thereby driving the transmission unit 1 to operate;

[0072] When the device is powered off, the attraction of the electromagnet will disappear instantly. At this time, the locking block 26 and the locking housing 23 will lose the magnetic attraction of the electromagnet. The locking block 26 will be reset under the traction of the second spring 25. At the same time, the drive motor 22 will also be reset under the force of the first spring 24, thereby allowing the drive motor 22 to detach from the locking housing 23.

[0073] Specifically, a buffer plate 36 is provided on the side of the hinge block 31 away from the hydraulic rod. The buffer plate 36 is connected to the extension plate 312 via a fourth spring 37. The inner wall of the sliding groove away from the hydraulic box 41 is slidably connected to the buffer plate 36, and the buffer plate 36 contacts the baffle 12.

[0074] In this embodiment, it is considered that when the hinge block 31 drives the connecting block 32 to move, the pressing unit 8 may directly contact the slow-stop shaft due to excessive speed and force, and generate a large pressure. This may cause the pressing unit 8 and the slow-stop shaft to be damaged by the high speed impact. At the same time, the large pressure may cause the slow-stop shaft to stop quickly, causing the objects on the transmission unit 1 to fall due to inertia.

[0075] When the hinge block 31 and the connecting block 32 move, the buffer plate 36 is in direct and constant contact with the baffle 12, and the setting of the fourth spring 37 allows the buffer plate 36 to accumulate force due to the shortening of the distance between the buffer plate 36 and the baffle 12. During the force accumulation process, the force of the drive unit 2 on the transmission unit 5 can be slowed down, thereby avoiding the pressure block 33 from contacting the slow-stop shaft too quickly, and preventing the slow-stop shaft from being subjected to a large force and stopping quickly.

[0076] Specifically, a tensioning unit 6 is fixedly connected between the baffles 12, and the tensioning unit 6 includes a fixing frame 61. Both ends of the fixing frame 61 are fixedly connected to the baffles 12. A plurality of tensioning holes are provided at the bottom of the baffle 12. The inner walls of the tensioning holes are slidably connected with a tensioning frame 62. The tensioning frame 62 is connected to the tensioning holes by a fifth spring 63. The inner wall of the tensioning frame 62 near the bottom is rotatably connected with a tensioning wheel 64, and the tensioning wheel 64 is rotatably connected to the transmission belt 11.

[0077] In this embodiment, the transmission belt 11 is generally provided with a redundant length to prevent breakage. However, if the redundant length is too short, it may still break when transmitting heavy objects. If the redundant length is too long, the shaft 13 may not be able to properly transmit the transmission belt 11, causing the transmission belt 11 to malfunction.

[0078] In order to prevent the transmission belt 11 from breaking, a longer redundancy can be used, and the tension of the transmission belt 11 is maintained by the tensioning unit 6. Under normal circumstances, the fifth spring 63 will push the tensioning frame 62, so that the tensioning wheel 64 contacts the transmission belt 11, and thereby tighten the redundancy of the transmission belt 11; when encountering heavier objects that cause the transmission belt 11 to be stretched, the transmission belt 11 in contact with the tensioning wheel 64 will be pulled, and the tensioning wheel 64 will move upward. At this time, the tensioning frame 62 will compress the fifth spring 63 and keep the transmission belt 11 in a suitable tensioning range.

[0079] Specifically, a pneumatic housing 38 is fixed on the side of the connecting block 32 away from the pressing block 33, and a pneumatic hole is opened on the same side of the connecting block 32; a pneumatic plate 39 is slidably connected to the inner wall of the pneumatic housing 38, and the side of the pneumatic housing 38 away from the connecting block 32 is fixedly connected to the isolation cover 14 through an air pressure tube 16, and the end of the air pressure tube 16 away from the pneumatic housing 38 is slidably connected to the emergency stop button 15; the emergency stop button 15 is used to stop the equipment urgently, and the emergency stop button 15 is electrically connected to the power supply of the equipment.

[0080] In this embodiment, when a person is caught in the transmission belt 11, the emergency stop button 15 can be pressed to cut off the power to the equipment. At the same time, the air inside the pneumatic tube 16 will be pushed, and the airflow will be introduced into the starting shell to push the pneumatic plate 39 to move. At this time, the pneumatic plate 39 will push the air from the pneumatic hole to the pressure hole. Since the air pressure in the pressure hole increases, it will continue to push the pressure block outward and make it impossible to reset the pressure block. This can make the equipment stop quickly, thereby achieving the effect of emergency stop.

[0081] When using,

[0082] First, during normal operation of the device, the arrangement of the clamping block and the locking block 26 allows the locking block 26 to be sucked outward when the electromagnet is energized. Since the locking housing 23 is fixed to the drive shaft, only the drive motor 22 moves. When the drive motor 22 moves, it compresses the first spring 24. Through the contact between the clamping block and the locking block 26, the output shaft of the drive motor 22 rotates, driving the locking housing 23 to rotate, thereby rotating the drive shaft, thereby driving the transmission unit 1 to operate;

[0083] During normal use, the first gear 44 is not connected to the connecting shaft 46 and the second gear 45. At this time, the connecting plate 18 will rotate downward under the influence of gravity. At this time, the connecting plate 18 can be placed on the subsequent device, thereby transferring items to the subsequent device.

[0084] Secondly, when the machine is shut down in a non-emergency situation or encounters a power outage, the drive motor 22 will shut down due to power loss. At the same time, the electromagnet will lose power and will lose its lock with the locking unit 7. At the same time, under the action of the first spring 24, the drive motor 22 will completely disengage from the locking unit 7, and the drive motor 22 will slide on the motor frame 21 through the hinge shaft. When the hinge shaft moves, it will push the transmission unit 5 to move. Since the transmission unit 1 is not directly connected to the drive motor 22, the drive motor 22 will not directly stop the transmission unit 1 after the power is cut off. Instead, the transmission unit 1 will continue to transmit according to inertia, so as to prevent the objects on the transmission unit 1 from falling due to inertia caused by the momentary stop, thereby avoiding damage to the objects caused by falling.

[0085] When the driving unit 2 pushes the transmission unit 5 to move due to a shutdown, since the hinge between the support frame 51 and the connecting rod 52 is closer to the driving unit 2, when the driving unit 2 pushes the connecting rod 52, only a short stroke is required to make the slow-stop unit 3 move a longer stroke.

[0086] When the connecting rod 52 pushes the hinge block 31 to move, it will also push the connecting block 32 to move. Since the connecting rod 52 will rotate in an arc when pushing the hinge block 31 to move, the hinge block 31 and the connecting block 32 will follow the arc rotation and make the connecting block 32 closer to the slow-stop shaft, so that the pressing unit 8 contacts the slow-stop shaft and the equipment is slowly stopped through friction.

[0087] At the same time, in order to prevent breakage, the transmission belt 11 can use a longer redundancy, and the tension of the transmission belt 11 is maintained by the tensioning unit 6. Under normal circumstances, the fifth spring 63 will push the tensioning frame 62 to make the tensioning wheel 64 contact with the transmission belt 11, thereby tightening the redundancy of the transmission belt 11; when encountering heavier objects that cause the transmission belt 11 to be stretched, the transmission belt 11 in contact with the tensioning wheel 64 will be pulled, and the tensioning wheel 64 will move upward. At this time, the tensioning frame 62 will compress the fifth spring 63 and keep the transmission belt 11 in a suitable tensioning range.

[0088] Finally, while the equipment slowly stops, the hydraulic rod is moved toward the inside of the hydraulic box 41 by pressing down the hinge block 31, and the hydraulic power is transmitted to the hydraulic gear rack 43 through the hydraulic pipe 42, and the first gear 44 is pushed to move. Since the height of the connecting shaft 46 is half of the second gear 45, when the first gear 44 moves, it will first engage with the second gear 45 and then engage with the connecting shaft 46. At this time, the connection between the connecting shaft 46 and the buffer shaft will generate power for the first gear 44, and through the engagement with the second gear 45, the second gear 45 drives the connecting plate 18 to rotate with the connecting rod as the axis, so that the connecting plate 18 is lifted to prevent the objects on the transmission unit 1 from continuing to move. At this time, the connecting plate 18 is lifted by the remaining power of the buffer shaft, thereby achieving the goal of still being lifted even when the power is off, and protecting the objects from The lifting angle of the connecting plate 18 is perpendicular to the transmission unit 1, which may cause subsequent objects to collide with the objects in front and fail to unload the force, causing fragile objects to be broken due to the impact. Since the transmission unit 1 will be slowly stopped by the friction of the slow-stop unit 3, the angle at which the connecting plate 18 can be lifted will not be perpendicular to the transmission unit 1, thereby causing the connecting plate 18 to tilt outward. When the transmission unit 1 slowly stops, some objects will slide onto the connecting plate 18 due to inertia. However, due to the inclination of the connecting plate 18, when subsequent objects collide, the objects in front can move onto the connecting plate 18 to unload the force, and the inclined connecting plate 18 can make the objects retreat under gravity, so that they will not stay on the connecting plate 18 for a long time. At the same time, since the transmission unit 1 is already in a slowly stopped state, the impact of subsequent objects will also be reduced.

[0089] When an emergency occurs,

[0090] Pressing the emergency stop button 15 can cut off the power to the device, and at the same time, the air inside the air pressure tube 16 is pushed, and the air flow is directed into the starting shell to push the pneumatic plate 39 to move. At this time, the pneumatic plate 39 pushes the air from the pneumatic hole to the pressure hole. As the air pressure in the pressure hole increases, it will continue to push the pressure block outward and make it unable to reset. This can quickly stop the device and achieve the effect of emergency stop.

[0091] When the pressure is high, the slow stop shaft can push the air inside the damping wheel 34 and make the slow stop shaft directly contact with the pressure block 33, thereby obtaining a larger contact area and a faster braking speed.
