Description

Technical Field

[0001] The present invention relates to the technical field of goods gripping and feeding, and particularly to an automatic identification and feeding device for goods in an automated production line. Background Art

[0002] With the continuous improvement of the level of industrial automation, especially in the manufacturing and logistics fields, the requirements for the efficiency and accuracy of production lines are gradually increasing. The application of automated production lines not only greatly reduces the need for manual operations, but also effectively improves production efficiency and reduces error rates, thus realizing refined and intelligent management of the production process. In this process, as one of the key equipment of the production line, the automatic feeding device plays an important role. At the same time, with the development of technology, the current automatic feeding device can also perform corresponding identification according to various synchronous factors such as the shape and weight of the goods, and then adopt corresponding grasping and feeding operations;

[0003] When the current automatic feeding device faces goods of different weights, it is difficult to meet different grasping operations. The common feeding and grasping operations mostly control mechanical claws to hold both sides of the goods box. When the goods are too heavy, the goods box may deform under the action of gravity and fall off the claws, resulting in poor stability and reliability of the traditional feeding device during the gripping and feeding process.

[0004] Therefore, how to provide an automatic identification and feeding device for goods in an automated production line is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] An object of the present invention is to provide an automatic identification and feeding device for goods in an automated production line. The present invention can effectively adapt to the gripping, transporting and feeding operations of goods boxes of different weights, and has a higher degree of automation, stronger reliability and greater stability compared with the traditional automatic feeding device.

[0006] An automatic identification and feeding device for goods in an automated production line according to an embodiment of the present invention includes a movable table and a gripping assembly. The gripping assembly is swingably arranged below the movable table through a control assembly. The gripping assembly includes a motor group, an adjusting assembly and two groups of claws. The motor group fixed at the bottom of the swing seat drives the two groups of claws to contract through the adjusting assembly to clamp the goods box on the top of the weight identification conveyor belt. A turning protrusion is separately arranged at the bottom of one side of the weight identification conveyor belt close to the goods box;

[0007] The control component includes a swing base and a motor. The motor is fixed to the bottom of one side of the movable table and is used to drive the swing base to swing at the bottom of the movable table. Rotating center rods are arranged at the middle positions on both sides of the swing base. The rotating center rods are rotatably connected to the frame plate at the bottom of the movable table through bushings. Stabilizing mechanisms are also arranged on both sides of the swing base. The stabilizing mechanisms include outer frames, two groups of planetary gears and sun gears. The two groups of planetary gears are rotatably arranged on the side surface of the swing base through shaft pins. The planetary gears are engaged between the sun gear and the outer frame;

[0008] A bottom support mechanism is arranged below one side of the movable table. The bottom support mechanism includes a sliding frame and a telescopic frame. The telescopic frame is slidably arranged up and down below the sliding frame. The top of the sliding frame is horizontally slidably connected to the movable table through a limit slider. An active belt component is vertically and fixedly arranged at the bottom of the telescopic frame.

[0009] Further, the output shaft of the motor is fixedly connected to a unidirectional lead screw. One end of the unidirectional lead screw is unidirectionally driven and connected to a reciprocating lead screw through a unidirectional ratchet component. One end of the reciprocating lead screw is rotatably connected to the movable table through a bearing.

[0010] Further, the surface of the unidirectional lead screw drives two groups of roller pushers to move horizontally on the top surface of the swing base through a nut pair. Oblique protrusions are respectively fixedly arranged on both sides of the top surface of the swing base. The roller pushers push against the oblique protrusions to drive the swing base to swing around the rotating center rod as the center.

[0011] Further, the reciprocating lead screw threadedly penetrates through the middle position of the sliding frame. The rotation of the reciprocating lead screw drives the sliding frame to reciprocate below one side of the movable table. Two groups of transmission shafts are rotatably arranged inside the sliding frame. Two groups of climbing teeth are fixed on the surfaces of the transmission shafts. The output shaft of a single group of transmission shafts is fixedly connected to the output shaft of a climbing motor. The climbing motor is fixed to the side surface of the sliding frame.

[0012] Further, climbing engaging grooves are formed at the positions of the telescopic frame close to the climbing teeth. The climbing engaging grooves are engaged with the climbing teeth. Opposite engaging teeth are fixedly arranged at one ends of the two groups of transmission shafts. The opposite engaging teeth are engaged with each other.

[0013] Further, the outer frame is fixedly connected to the movable table. Arc-shaped engaging grooves are respectively formed on both sides of the inner surface of the outer frame. The arc-shaped engaging grooves are engaged with the planetary gears. The sun gear is rotatably connected to one end of the rotating center rod.

[0014] Further, locking mechanisms are arranged above the positions close to the outer convex teeth on both sides of the movable table. The outer convex teeth are fixed at the center of the sun gear. The locking mechanisms include electric push rods, levers and tooth engaging protrusions. The electric push rods drive the tooth engaging protrusions to move up and down above the outer convex teeth through the levers. The tooth engaging protrusions are engaged with the top of the outer convex teeth.

[0015] Further, the electric push rod is fixed on the side of the movable table. Activity chutes are respectively opened on both sides of the lever. Sliding pins are slidably arranged in the activity chutes. One side of a single group of sliding pins is fixedly connected to the output end of the electric push rod through a connecting rod, and one side of the other group of sliding pins is fixedly connected to the tooth convex through a carriage.

[0016] Further, a return spring is also sleeved on the surface of the carriage between the sliding pin and the tooth convex. A bearing seat is arranged at the position of the movable table close to the return spring. The sliding pin is elastically connected to the movable table through the return spring.

[0017] Further, a through hole is opened at the position on the surface of the lever away from the electric push rod. An axle pin is rotatably arranged in the through hole, and the axle pin is fixedly connected to the movable table.

[0018] The beneficial effects of the present invention are as follows:

[0019] By arranging a control component between the movable table and the grasping component, after the motor is started, the pushing roller can be driven to move on the top of the swing seat by the rotation of the one-way lead screw, so as to push and squeeze the inclined convex, causing the swing seat to deflect with the rotation center rod as the center, thereby driving the lower holding claws to change the angle. During this process, the movable table continuously drives the grasping component to move as a whole, and the holding claws hook the cargo box. In this way, the cargo box will tilt to one side with the raised position of the flipping convex as the center on the top of the weight recognition conveyor belt, and at the same time, the reciprocating lead screw is driven to rotate and then drive the movable belt component to extend between the weight recognition conveyor belt and the cargo box. After completely entering, the movable table resets, and the cargo box can just fall on the movable belt component, so as to provide better bottom support force for the cargo box through the movable belt component, and further adapt to the heavier cargo box to prevent the cargo box from detaching from the holding claws during the handling and loading process.

[0020] By arranging a stabilizing mechanism on both sides of the swing seat, the outer frame is directly fixed to the movable table. During the deflection process of the swing seat, the swing seat will drive two groups of planetary gears to rotate between the arc-shaped meshing grooves and the sun gear through the shaft rod. During this process, the two groups of planetary gears drive the sun gear to rotate with the rotation center rod as the center. Under the connection of the bottom side plate of the movable table and the meshing action between the planetary gears and the arc-shaped meshing grooves and the sun gear, the stability during the deflection process of the swing seat is improved, and the deflection force actually borne by the rotation center rod is shared.

[0021] In the present invention, a locking mechanism is provided above the convex teeth. After the electric push rod is started, it can push one side of the lever downward through the sliding effect of a single set of sliding pins and the movable chute. At this time, the other side of the lever moves upward, lifting the engaging tooth convex to separate from the convex teeth. At this time, the swing seat can normally drive the planetary gear to engage and rotate between the arc-shaped engaging groove and the sun gear. The sun gear is stressed and rotates in cooperation with the planetary gear. On the contrary, when the engaging tooth convex abuts against the sun gear, the sun gear is limited by the engaging tooth convex and the movable table at this time and cannot continue to rotate. As a result, the outside of the planetary gear is restricted by the arc-shaped engaging groove, and the inside is restricted by the sun gear. Furthermore, by restricting the position of the planetary gear, the stability effect of the swing seat is provided, preventing the heavy weight of the cargo box from affecting the normal use of the control component and improving the reliability of the device.

Detailed implementation mode

[0033] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present invention in a schematic way, so they only show the components related to the present invention.

[0034] Reference Figures 1 - 8 , including a movable table 1 and a gripping component 3. The gripping component 3 is swingably arranged below the movable table 1 through a control component 2. The gripping component 3 includes a motor group 31, an adjustment component 32 and two groups of clamping claws 33. The motor group 31 fixed at the bottom of the swing seat 21 drives the two groups of clamping claws 33 to contract through the adjustment component 32 to clamp the cargo box 4 on the top of the weight identification conveyor belt 5. A flipping protrusion 6 is separately arranged at the bottom of one side of the weight identification conveyor belt 5 close to the cargo box 4;

[0035] The control component 2 includes a swing seat 21 and an electric motor 26. The electric motor 26 is fixed at the bottom of one side of the movable table 1 and is used to drive the swing seat 21 to swing at the bottom of the movable table 1. A pivot rod 23 is arranged at the middle position on both sides of the swing seat 21. The pivot rod 23 is rotationally connected to the frame plate at the bottom of the movable table 1 through a bushing. A stabilizing mechanism 7 is also arranged on both sides of the swing seat 21. The stabilizing mechanism 7 includes an outer frame 71, two groups of planetary gears 73 and a sun gear 74. The two groups of planetary gears 73 are rotationally arranged on the side surface of the swing seat 21 through a shaft pin, and the planetary gears 73 are engaged between the sun gear 74 and the outer frame 71;

[0036] A bottom support mechanism 9 is arranged below one side of the movable table 1. The bottom support mechanism 9 includes a sliding frame 91 and a telescopic frame 92. The telescopic frame 92 is slidably arranged up and down below the sliding frame 91. The top of the sliding frame 91 is horizontally slidably connected to the movable table 1 through a limit slider. An activity belt assembly 98 is vertically and fixedly arranged at the bottom of the telescopic frame 92.

[0037] In this embodiment, the control component 2 is connected to the movable platform 1 and the gripping component 3. Driven by the motor 26, the swing seat 21 can synchronously drive the gripping component 3 as a whole to perform a small-angle deflection operation, thereby changing the actual gripping angle position of the claw 33, so that it can adapt to the gripping operation of different cargo boxes and increase the gripping range.

[0038] Furthermore, after the claws 33 have normally grasped the cargo box 4, the motor 26 drives the grasping assembly 3 to deflect as a whole, at which time the claws 33 will hook the handle position of the cargo box 4, and the bottom of the cargo box 4 will be restricted by the flip protrusion 6 on one side of the weight recognition conveyor belt 5, so that the swinging effect will drive the cargo box 4 to deflect as a whole. This operation is suitable for grasping operations of heavier cargo boxes 4. In the process of driving the cargo box 4 to deflect, the motor 26 will synchronously drive the sliding frame 91 to slide on one side of the movable platform 1, and the sliding frame 91 will drive the telescopic frame 92 to move until the telescopic frame 92 drives the movable belt assembly 98 to be under the cargo box 4. At this time, if the reset operation is realized, a part of the bottom area of ​​the cargo box 4 will fall on the movable belt assembly 98, and the movable belt assembly 98 will perform a bottom supporting operation, thereby alleviating the force on the handle position of the cargo box 4 and the claws 33, thereby protecting the cargo box 4 from damage, which is suitable for loading and grasping operations of heavier cargo boxes 4.

[0039] refer to Figure 3 , Figure 5 and Figure 8 The output shaft of the motor 26 is fixedly connected to the one-way screw 25, one end of which is connected to the reciprocating screw 28 through the one-way ratchet assembly 27, and one end of the reciprocating screw 28 is rotatably connected to the movable platform 1 through a bearing. The surface of the one-way screw 25 drives two sets of push rollers 24 to move horizontally on the top surface of the swing seat 21 through a nut pair, and inclined protrusions 22 are fixedly arranged on both sides of the top surface of the swing seat 21. The push rollers 24 push the inclined protrusions 22 to drive the swing seat 21 to swing with the rotating rod 23 as the center.

[0040] In this embodiment, the output shaft of the motor 26 is first connected to the one-way screw 25, and the surface of the one-way screw 25 is threadedly connected to the nut pair. After the motor 26 drives the one-way screw 25 to rotate, the nut pair on its surface will drive the two sets of push rollers 24 below to move on the top surface of the swing seat 21, so that the push rollers 24 push the inclined protrusions 22 on the top of the swing seat 21, and the two sides of the swing seat 21 are limited by the side seats of the movable platform 1, so that the swing seat 21 can only rotate with the rotating rod 23 as the center, thereby controlling the actual deflection angle of the lower gripping component 3;

[0041] While driving the swing seat 21 to change the angle, one end of the one-way lead screw 25 is connected to the reciprocating lead screw 28 through the one-way ratchet assembly 27. When rotating in one direction, the reciprocating lead screw 28 is synchronously stressed and rotates, causing the control underframe mechanism 9 to perform a reciprocating motion. When resetting in the reverse direction, the one-way ratchet assembly 27 prevents the one-way lead screw 25 from transmitting the driving effect to the reciprocating lead screw 28. The underframe mechanism 9 can support the bottom of the cargo box 4 at a specified position, and the rotation of the one-way lead screw 25 makes the cargo box 4 gradually tend to be level. Specifically: Inside the one-way ratchet assembly 27, the one-way lead screw 25 can be connected to the ratchet frame, and the reciprocating lead screw 28 is connected to the ratchet teeth.

[0042] Reference Figure 3 , the reciprocating lead screw 28 threadedly penetrates through the middle position of the sliding frame 91. The rotation of the reciprocating lead screw 28 drives the sliding frame 91 to reciprocate under the side of the movable platform 1. Two groups of transmission shafts 94 are rotatably arranged inside the sliding frame 91. Two groups of climbing teeth 95 are fixed on the surface of the transmission shafts 94. A single group of transmission shafts 94 is fixed to the output shaft of the climbing motor 93, and the climbing motor 93 is fixed on the side surface of the sliding frame 91. A climbing engaging groove 97 is provided at a position of the telescopic frame 92 close to the climbing teeth 95, and the climbing engaging groove 97 meshes with the climbing teeth 95. Opposite engaging teeth 96 are fixedly arranged at one end of the two groups of transmission shafts 94, and the two groups of opposite engaging teeth 96 mesh with each other.

[0043] In this implementation scheme, the threaded transmission connection of the reciprocating lead screw 28 causes the sliding frame 91 to be stressed and move and perform a reciprocating folding motion at the limit position of the reciprocating lead screw 28 after the reciprocating lead screw 28 rotates, thereby driving the telescopic frame 92 and the movable belt assembly 98 below the sliding frame 91 to perform a reciprocating motion, enabling the movable belt assembly 98 to normally extend under the cargo box 4 and between the weight recognition conveyor belt 5. At the same time, after the climbing motor 93 is started, the two groups of transmission shafts 94 can rotate in opposite directions through the two groups of opposite engaging teeth 96 that mesh with each other. The rotation effect drives the two groups of climbing teeth 95 to rotate, and the two groups of climbing teeth 95 engage with the climbing engaging grooves 97 on the surface of the telescopic frame 92, causing the telescopic frame 92 to move up and down due to the rotation effect of the climbing teeth 95, changing the actual height position of the movable belt assembly 98, enabling the movable belt assembly 98 to provide a better bottom support effect for the bottom of the cargo box 4 during normal transportation, and at the same time satisfying the storage operation of the movable belt assembly 98 to prevent the lateral movement of the movable platform 1 from driving the movable belt assembly 98 to collide with other components.

[0044] Reference Figures 5 - 7 , the outer frame 71 is fixedly connected to the movable platform 1. Arc-shaped engaging grooves 72 are respectively provided on both sides of the inner surface of the outer frame 71, and the arc-shaped engaging grooves 72 mesh with the planetary teeth 73. The sun gear 74 is rotatably connected to one end of the rotating center rod 23.

[0045] In this embodiment, the sun gear 74 is movably mounted on one end of the swivel rod 23. During the deflection of the swing seat 21, the swing seat 21 drives the planetary gear 73 to move between the arc-shaped engaging groove 72 and the sun gear 74, causing the sun gear 74 to move synchronously. Compared with the swing seat 21 being directly pushed to deflect, this connection effect will improve the stability of the swing seat 21 during movement.

[0046] Reference Figures 5 - 7 , locking mechanisms 8 are provided at positions above the two sides of the movable table 1 near the outer convex teeth 75. The outer convex teeth 75 are fixed at the center of the sun gear 74. The locking mechanism 8 includes an electric push rod 81, a lever 82, and a tooth convex 83. The electric push rod 81 drives the tooth convex 83 to move up and down above the outer convex teeth 75 through the lever 82, and the tooth convex 83 engages with the top of the outer convex teeth 75.

[0047] In this embodiment, after the electric push rod 81 is started, it can push one side of the lever 82 downward, and the other side of the lever 82 will be forced to move upward, driving the separation between the tooth convex 83 and the outer convex teeth 75. At this time, the outer convex teeth 75 and the sun gear 74 can rotate normally.

[0048] Reference Figures 5 - 7 , the electric push rod 81 is fixed on the side of the movable table 1. Activity chutes 84 are respectively opened on both sides of the lever 82. Sliding pins 85 are slidably arranged in the activity chutes 84. One side of a single group of sliding pins 85 is fixedly connected to the output end of the electric push rod 81 through a connecting rod, and the other side of the other group of sliding pins 85 is fixedly connected to the tooth convex 83 through a sliding frame. A return spring 86 is also sleeved on the surface of the sliding frame between the sliding pin 85 and the tooth convex 83. A bearing seat is arranged at the position of the movable table 1 close to the return spring 86, and the sliding pin 85 is elastically connected to the movable table 1 through the return spring 86. A through hole is opened at a position on the surface of the lever 82 away from the electric push rod 81, and a shaft pin is rotatably arranged in the through hole, and this shaft pin is fixedly connected to the movable table 1.

[0049] In this embodiment, after the electric push rod 81 is started, first, the output rod of the electric push rod 81 drives the sliding pin 85 to slide inside the activity chute 84 on one side of the lever 82, causing the lever 82 to rotate around a certain point. This point is located at a position away from the surface of the lever 82 away from the electric push rod 81, reducing the actual required stroke of the electric push rod 81 and providing a greater lifting force. The lifting of the activity chute 84 on the other side of the lever 82 drives the sliding pin 85 to move upward. The sliding pin 85 drives the tooth convex 83 to separate from the outer convex teeth 75 through the sliding frame, and at the same time, the return spring 86 will be compressed. After the electric push rod 81 is released, the elastic action of the return spring 86 will drive the tooth convex 83 to engage with the outer convex teeth 75 again, providing a good locking effect for the sun gear 74.

[0050] Working principle: First, the movable table 1 moves on the crossbeam, driving the subsequent components above the weight recognition conveyor belt 5. After the weight recognition conveyor belt 5 works to drive the cargo box 4 under the gripping assembly 3, at this time, the motor group 31 drives the gripper 33 to approach the handle positions on both sides of the cargo box 4 through the adjustment assembly 32. Subsequently, the motor 26 works to drive the one-way lead screw 25 to rotate normally. The nut pair on the surface of the one-way lead screw 25 moves to drive the two sets of roller 24 to move on the top of the swing seat 21, so that the roller 24 contacts and abuts against the swing seat 21 with the inclined protrusion 22, causing the swing seat 21 to swing around the pivot rod 23. During the swing, the gripper 33 will change the inclined angle position. In this process, combined with the lateral movement of the movable table 1, the gripper 33 will pull the unilateral handle on the top of the cargo box 4, and the cargo box 4 will tilt with the flipping protrusion 6 as the base point at this time, and the bottom of one side of the cargo box 4 will be lifted;

[0051] Meanwhile, the lateral movement effect of the movable table 1 will drive the movable belt assembly 98 to move laterally. Before this, the rotation of the one-way lead screw 25 will synchronously drive the reciprocating lead screw 28 to rotate through the connection effect of the one-way ratchet assembly 27 and the reciprocating lead screw 28. The rotation of the reciprocating lead screw 28 will cause the sliding frame 91 to perform screw drive at the bottom of one side of the movable table 1, accelerating it to approach between the cargo box 4 and the weight recognition conveyor belt 5. At the same time, by starting the climbing motor 93, the climbing motor 93 drives the two sets of counter-rotating drive shafts 94 to rotate in opposite directions through the two sets of meshing counter-rotating teeth 96. The two sets of climbing teeth 95 on the surface of the drive shaft 94 will engage with the climbing tooth grooves 97 on the surface of the telescopic frame 92, causing the climbing tooth grooves 97 to move up and down a certain distance at the bottom of the sliding frame 91, so as to better align the movable belt assembly 98 with the cargo box 4 and the weight recognition conveyor belt 5, and finally until the movable belt assembly 98 is completely inserted between the cargo box 4 and the weight recognition conveyor belt 5;

[0052] By reverse-driving the motor 26, the one-way lead screw 25 reverses. Under the connection effect of the one-way ratchet assembly 27, the reciprocating lead screw 28 will not rotate, causing the gripper 33 to drive the cargo box 4 to reset until the bottom is completely flush with the movable belt assembly 98. At this time, the climbing motor 93 drives the movable belt assembly 98 to rise a certain distance again to provide a bottom support effect for the bottom of the cargo box 4, and cooperate with the clamping of the two sets of grippers 33 to achieve better clamping operation;

[0053] During the deflection of the pendulum seat 21, the two sides of the pendulum seat 21 will drive the planetary gears 73 to rotate between the sun gear 74 and the outer frame 71, and the inner position of the planetary gear 73 will engage with the arc-shaped groove 72 of the inner circle of the outer frame 71, so that the pendulum seat 21 is more stable during the deflection process. In the process of driving the cargo box 4 to move horizontally to achieve loading, the electric push rod 81 will pull one side of the lever 82 upward through the sliding effect of the sliding pin 85 sliding inside the movable slide groove 84, so that the other side of the lever 82 moves downward, driving the locking tooth 83 to resist the outer convex tooth 75 on one side of the sun gear 74, thereby preventing the sun gear 74 from rotating. At this time, the activity of the planetary gear 73 is limited, thereby stabilizing the state of the pendulum seat 21.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
