The two limit plates 13 are positioned above the upper belt surface of the rear conveying belt 2, and the width between the two limit plates 13 is slightly larger than or equal to the width of the workpiece 3; in an initial state, a larger distance exists between the positions of the two limiting plates 13 and the position of the sorting frame 6, so that after the sorting frame 6 rotates 180 degrees, the sorting frame 6 can be aligned to the two limiting plates 13, and the workpiece 3 on the sorting frame 6 can slide between the two limiting plates 13. As shown in fig. 4, in the initial state, one end of the sorting frame 6 where the ladder-type weight 22 is located exceeds the bandwidth of the front conveyor belt 1, so as to ensure that one end of the workpiece 3 does not fall above the ladder-type weight 22 when the workpiece 3 falls in the ladder-type space of the sorting frame 6, and ensure that the workpiece 3 can be sorted smoothly and orderly. The inner shaft 15 and the outer shaft 16 are inclined towards the direction of the front conveying belt, and an acute angle formed between the outer shaft 16 and the base 10 is 10-15 degrees, so that the sorting frame 6 is ensured to move obliquely upwards along the axial direction of the inner shaft 15 while moving in the rotating direction to the maximum extent, and the movement interference between the sorting frame 6 and the front output belt and the rear conveying belt 2 is avoided.

Because the workpieces 3 can basically fall or be put on the front conveyor belt 1 in an equidistant mode in the early stage of production and transmission, but the workpieces 3 are often not orderly arranged on the front conveyor belt 1, and in most cases, the workpieces 3 are randomly arranged on the conveyor belt, that is, the included angle between the workpieces 3 on the front conveyor belt 1 and the width direction of the front conveyor belt 1 is different. When the included angle between the individual workpiece 3 on the front conveying belt 1 and the front conveying belt 1 in the width direction is zero, the workpiece 3 can directly and completely fall into the trapezoidal space of the sequencing frame 6 under the conveying of the front conveying belt 1; when the included angle between most of the workpieces 3 on the front conveyor belt 1 and the width direction of the front conveyor belt 1 is not zero, one end of each workpiece 3 enters the ladder-shaped space of the sorting frame 6 from the end of the front conveyor belt 1 under the conveying of the front conveyor belt 1, and the other end of each workpiece 3 is still on the front conveyor belt 1; one end of the workpiece 3 can be pressed against the baffle 5 under the continuous conveying of the front conveying belt 1; however, since the electric drive module 19 of the present invention employs a self-locking motor, the gear a 18 will not rotate under the action of external force, and thus the gear B17, the outer shaft 16 and the inner shaft 15 will not swing freely, and the sequencing rack 6 and the baffle 5 will not swing. That is, when one end of the workpiece 3 abuts against the baffle 5, the baffle 5 does not act and the workpiece 3 automatically swings along with the conveying of the front conveyor belt; as the front conveyor belt 1 continues to convey, the other end of the workpiece 3 enters the ladder-shaped space of the sorting rack 6 from the end of the front conveyor belt 1, and during the time, the workpiece 3 is automatically swung from the inclined state to the direction consistent with the length direction of the sorting rack 6, namely, the workpiece 3 is parallel to the width direction of the front conveyor belt 1 under the blocking action of the baffle 5. After the workpieces 3 completely enter the trapezoidal space of the sequencing shelf 6, the inclined plate 24 without the baffle 5 is mainly used for preventing the workpieces 3 from falling off from the direction far away from the baffle 5, and the baffle 5 mainly plays a role of shielding the workpieces 3.

When the workpiece 3 completely enters the trapezoidal space of the sorting frame 6 and is stable, the electric driving module 19 is started to drive the gear A18 to rotate, the gear A18 drives the outer shaft 16 to rotate through the gear B17, the outer shaft 16 drives the inner shaft 15 to synchronously rotate through the guide block A27, the external threads on the inner shaft 15 are in threaded fit with the internal threads of the threaded sleeve, and the inner shaft 15 drives the sorting frame 6 to move in the rotating direction and also move obliquely upwards along the axial direction of the inner shaft 15; after the rotating inner shaft 15 drives the sorting frame 6 to rotate 180 degrees, as shown in fig. 17, the sorting frame 6 is aligned with the two limiting plates 13, and the heights of the two ends of the sorting frame 6 are different; one end of the sequencing frame 6 where the ladder-shaped weight 22 is located in the initial state is the high end of the sequencing frame 6 which is rotated by 180 degrees, and one end of the sequencing frame 6 where the ladder-shaped weight 22 is far away from in the initial state is the low end of the sequencing frame 6 which is rotated by 180 degrees; the lower end port of the sequencing frame 6 is close to and aligned between the two limit plates 13, and the lower end of the sequencing frame 6 does not interfere with the movement of the two limit plates 13. In the process that the sequencing frame 6 rotates 180 degrees, one end of the sequencing frame 6 where the ladder-type weight 22 is located is gradually raised, and one end of the sequencing frame 6 far away from the ladder-type weight 22 is gradually lowered; during this period, because the workpiece 3 is in friction contact with the wall surface where the trapezoidal space of the sorting frame 6 is located, the gliding force generated by the gravity of the workpiece 3 is not enough to overcome the friction between the workpiece 3 and the sorting frame 6, so the workpiece 3 cannot slide from the trapezoidal space of the sorting frame 6; during this period, since the height difference between the two ends of the sequencing frame 6 gradually increases, the downward sliding force of the ladder-type weight 22 under its own weight gradually presses the large-angle inclined surface 40 of the blocking block 35, the blocking block 35 slightly moves toward the headed screw 38, and the spring 37 is further compressed. After the sequencing frame 6 rotates 180 degrees, the height difference between the high end of the sequencing frame 6 and the low end of the sequencing frame 6 reaches the maximum, so that the downward sliding force generated by the ladder-type weight 22 under the self gravity can just overcome the large-angle inclined surface 40 of the blocking block 35, the ladder-type weight 22 can extrude and pass through the blocking block 35, the blocking block 35 moves towards the headed screw 38, and the spring 37 is further compressed; after ladder-type pouring weight 22 moves down a little distance, hinder piece 35 and the corresponding holding tank 34 on ladder-type pouring weight 22, so under spring 37's reset effect, hinder piece 35 and insert into holding tank 34 fast, slide along with moving down of ladder-type pouring weight 22, hinder piece 35 and slide in holding tank 34 relatively, just so can avoid ladder-type pouring weight 22 to move down the slip in-process, hinder piece 35 and cause the friction obstacle to the bottom surface of ladder-type pouring weight 22, guarantee that ladder-type pouring weight 22 can smoothly move the slip underground. During the downward sliding movement of the ladder weight 22, the interference block 35 is relatively disengaged from the receiving groove 34 of the ladder weight 22.

When the ladder-type weight 22 moves up and down and slides on the sequencing frame 6 by utilizing gravitational potential energy, the ladder-type weight 22 impacts one end of the workpiece 3, the pushing of the ladder-type weight 22 to the workpiece 3 is enough to overcome the friction between the workpiece 3 and the inner wall of the sequencing frame 6, and therefore the ladder-type weight 22 can push the workpiece 3 out of the sequencing frame 6 gradually. One end of the workpiece 3, which is far away from the ladder-shaped weight 22, penetrates out of the sequencing frame 6 and enters between the two limiting plates 13, and is gradually pushed out of the sequencing frame 6 along with the workpiece 3, one end of the workpiece 3, which is far away from the ladder-shaped weight 22, is in contact with the upper belt surface of the rear conveying belt 2, and the rear conveying belt 2 provides a pushing force for the workpiece 3, but at the moment, because the two limiting plates 13 limit the swinging of the workpiece 3, one end of the workpiece 3, which is far away from the ladder-shaped weight 22, is not swung after being in contact with the upper belt surface. When the ladder-shaped weight 22 completely pushes the workpiece 3 out of the sequencing frame 6, one end of the workpiece 3 close to the ladder-shaped weight 22 enters between the two limiting plates 13, and the workpiece 3 is still limited by the two limiting plates 13 and cannot swing; when the workpiece 3 is completely separated from the sorting frame 6, the workpiece 3 completely and automatically drops on the rear conveying belt 2 under the action of self gravity, and the distance between the two limiting plates 13 and the upper belt surface of the rear conveying belt 2 is greater than the height of the workpiece 3, so that the workpiece 3 is not limited by the two limiting plates 13, and the workpiece 3 is conveyed to the next procedure for sorting or packaging along with the rear conveying belt 2. When the work piece 3 does not completely slide from between two limiting plates 13, two limiting plates 13 play the effect of limit pendulum to work piece 3, prevent the work piece 3 conveying of transmission band 2 afterwards and swing, guarantee that work piece 3 can be carried with being on a parallel with back transmission band 2 bandwidth direction basically, the work piece 3 of landing on back transmission band 2 will become orderly like this, the arrangement or the packing of the next process of being convenient for very much.

After the workpiece 3 slides onto the rear conveyor belt 2, according to a set time instruction in the control system, the control system controls the electric drive module 19 to rotate reversely, the reversely rotating gear A18 drives the outer shaft 16 to rotate reversely through the gear B17, the outer shaft 16 drives the inner shaft 15 to synchronously rotate reversely through the guide block A27, the external thread on the inner shaft 15 is in threaded fit with the internal thread of the threaded sleeve, and the reversely rotating inner shaft 15 drives the sorting frame 6 to move in the rotating direction and also move obliquely downwards along the axial direction of the inner shaft 15; when the inner shaft 15 rotates reversely to drive the sorting frame 6 to rotate 180 degrees, the sorting frame 6 is restored to the initial state. In the initial state of the sequencing frame 6, the central line of the sequencing frame 6 in the length direction and the central axis of the carrier roller 4 where the front conveying belt 1 is located form an included angle of 4-6 degrees; that is to say the sorting shelf 6 is inclined; the ladder-type weight 22 will move back obliquely downward along the direction of the sequencing rack 6, the blocking block 35 will relatively enter the receiving slot 34 of the ladder-type weight 22 again, the side wall of the receiving slot 34 will press the small-angle inclined surface 41 of the blocking block 35, the design of the small-angle inclined surface 41 can make the ladder-type weight 22 easily pass over the blocking block 35, the ladder-type weight 22 presses and passes over the blocking block 35, the blocking block 35 moves toward the direction of the headed screw 38, and the spring 37 is further compressed; after the ladder-type weight 22 completely passes over the blocking block 35, the ladder-type weight 22 moves down along the sequencing frame 6 to the extreme position and stops, the blocking block 35 returns to the initial position under the reset action of the spring 37, and the large-angle inclined surface 40 of the blocking block 35 is matched with the ladder-type weight 22. Finally, the ladder-type weights 22 on the sequencing frame 6 are restored to the original positions, and the interference blocks 35 are also restored to the original positions. Then, after waiting for a certain time, the new workpiece 3 is completely located in the ladder-shaped space of the sorting frame 6 again, and the control system controls the electric drive module 19 to drive the gear a 18 to operate again under the set interval time instruction, so that the above-mentioned procedure of driving the electric drive module 19 to rotate forward and backward is repeated to complete the sorting of the new workpiece 3 on the rear conveyor belt 2.

As shown in fig. 15 and 16, for the arrangement scheme that the conveying direction of the front conveying belt 1 is the same as that of the rear conveying belt 2, the conveying device of the invention does not need a D support 12, an L shaping plate 14 and a limiting plate 13, the operation and the resetting process are repeated, the length direction of the sequencing frame 6 is consistent with that of the rear conveying belt 2 after the sequencing frame 6 rotates 180 degrees, the workpieces 3 pushed out of the sequencing frame 6 can be directly matched with the rear conveying belt 2, the workpieces 3 can be conveyed basically in the direction parallel to the conveying direction of the rear conveying belt 2, and therefore the workpieces 3 sliding on the rear conveying belt 2 become orderly, and the arrangement or the packaging of the next process is very convenient.

For the arrangement scheme that the conveying direction of the front conveying belt 1 is perpendicular to the conveying direction of the rear conveying belt 2, the thin pressure sensor is used for executing reciprocating periodic actions, and each periodic action carries out one-time sequential arrangement on the workpieces 3; taking the work flow of executing one cycle action of the invention as an example: in an initial state, as shown in fig. 1 and 2, the sorting frame 6 is positioned between the front conveying belt 1 and the rear conveying belt 2, and as shown in fig. 2 and 4, an included angle formed by a central line of the sorting frame 6 in the length direction and a central axis of the carrier roller 4 where the front conveying belt 1 is positioned is between 4 and 6 degrees; as shown in fig. 3, the ladder-type weight 22 is located on the leftmost end surface of the sequencing frame 6; in the initial state, the end of the sequencing frame 6 where the ladder-shaped weight 22 is located is lower than the end of the sequencing frame 6 far away from the ladder-shaped weight 22. As shown in fig. 10, the end side surface of the ladder-shaped weight 22 is in contact fit with the large-angle inclined surface 40 of the blocking block 35; the spring 37 is in a pre-compressed state; the baffle 5 on the sequencing frame 6 is in a vertical state, the baffle 5 is higher than the upper belt surface of the rear conveying belt 2, the inclined plate 24 of the sequencing frame 6, which is not connected with the baffle 5, is lower than the upper belt surface of the front conveying belt, and the inclined plate 24 of the sequencing frame 6, which is not connected with the baffle 5, is at a certain distance from the end part of the front conveying belt 1, so that the sequencing frame 6 has enough swing space, and meanwhile, the workpieces 3 can be prevented from being leaked from the inclined plate 24 to the end part of the front conveying belt 1. The two limit plates 13 are positioned above the upper belt surface of the rear conveying belt 2, and the width between the two limit plates 13 is slightly larger than or equal to the width of the workpiece 3; in an initial state, a larger distance exists between the positions of the two limiting plates 13 and the position of the sorting frame 6, so that after the sorting frame 6 rotates 180 degrees, the sorting frame 6 can be aligned to the two limiting plates 13, and the workpiece 3 on the sorting frame 6 can slide between the two limiting plates 13. As shown in fig. 4, in the initial state, one end of the sorting frame 6 where the ladder-type weight 22 is located exceeds the bandwidth of the front conveyor belt 1, so as to ensure that one end of the workpiece 3 does not fall above the ladder-type weight 22 when the workpiece 3 falls in the ladder-type space of the sorting frame 6, and ensure that the workpiece 3 can be sorted smoothly and orderly. The inner shaft 15 and the outer shaft 16 are inclined towards the direction of the front conveying belt, and an acute angle formed between the outer shaft 16 and the base 10 is 10-15 degrees, so that the sorting frame 6 is ensured to move obliquely upwards along the axial direction of the inner shaft 15 while moving in the rotating direction to the maximum extent, and the movement interference between the sorting frame 6 and the front output belt and the rear conveying belt 2 is avoided.

When the workpiece 3 completely enters the trapezoidal space of the sequencing frame 6 and is stable, the workpiece 3 can press the thin pressure sensing piece 30 positioned in the middle of the sequencing frame 6, the pressed thin pressure sensing piece 30 transmits a pressing signal to the control system, the control system sets a recognition signal and makes an instruction for starting the electric driving module 19 after analyzing the recognition signal, the control system controls the electric driving module 19 to drive the gear A18 to rotate, the gear A18 drives the outer shaft 16 to rotate through the gear B17, the outer shaft 16 drives the inner shaft 15 to synchronously rotate through the guide block A27, the external thread on the inner shaft 15 is in threaded fit with the internal thread of the thread sleeve, and the inner shaft 15 drives the sequencing frame 6 to move in the rotating direction and also move obliquely upwards along the axial direction of the inner shaft 15; after the rotating inner shaft 15 drives the sorting frame 6 to rotate 180 degrees, as shown in fig. 17, the sorting frame 6 is aligned with the two limiting plates 13, and the heights of the two ends of the sorting frame 6 are different; one end of the sequencing frame 6 where the ladder-shaped weight 22 is located in the initial state is the high end of the sequencing frame 6 which is rotated by 180 degrees, and one end of the sequencing frame 6 where the ladder-shaped weight 22 is far away from in the initial state is the low end of the sequencing frame 6 which is rotated by 180 degrees; the lower end port of the sequencing frame 6 is close to and aligned between the two limit plates 13, and the lower end of the sequencing frame 6 does not interfere with the movement of the two limit plates 13. In the process that the sequencing frame 6 rotates 180 degrees, one end of the sequencing frame 6 where the ladder-type weight 22 is located is gradually raised, and one end of the sequencing frame 6 far away from the ladder-type weight 22 is gradually lowered; during this period, because the workpiece 3 is in friction contact with the wall surface where the trapezoidal space of the sorting frame 6 is located, the gliding force generated by the gravity of the workpiece 3 is not enough to overcome the friction between the workpiece 3 and the sorting frame 6, so the workpiece 3 cannot slide from the trapezoidal space of the sorting frame 6; during this period, since the height difference between the two ends of the sequencing frame 6 gradually increases, the downward sliding force of the ladder-type weight 22 under its own weight gradually presses the large-angle inclined surface 40 of the blocking block 35, the blocking block 35 slightly moves toward the headed screw 38, and the spring 37 is further compressed. After the sequencing frame 6 rotates 180 degrees, the height difference between the high end of the sequencing frame 6 and the low end of the sequencing frame 6 reaches the maximum, so that the downward sliding force generated by the ladder-type weight 22 under the self gravity can just overcome the large-angle inclined surface 40 of the blocking block 35, the ladder-type weight 22 can extrude and pass through the blocking block 35, the blocking block 35 moves towards the headed screw 38, and the spring 37 is further compressed; after ladder-type pouring weight 22 moves down a little distance, hinder piece 35 and the corresponding holding tank 34 on ladder-type pouring weight 22, so under spring 37's reset effect, hinder piece 35 and insert into holding tank 34 fast, slide along with moving down of ladder-type pouring weight 22, hinder piece 35 and slide in holding tank 34 relatively, just so can avoid ladder-type pouring weight 22 to move down the slip in-process, hinder piece 35 and cause the friction obstacle to the bottom surface of ladder-type pouring weight 22, guarantee that ladder-type pouring weight 22 can smoothly move the slip underground. During the downward sliding movement of the ladder weight 22, the interference block 35 is relatively disengaged from the receiving groove 34 of the ladder weight 22.

When the ladder-type weight 22 moves up and down and slides on the sequencing frame 6 by utilizing gravitational potential energy, the ladder-type weight 22 impacts one end of the workpiece 3, the pushing of the ladder-type weight 22 to the workpiece 3 is enough to overcome the friction between the workpiece 3 and the inner wall of the sequencing frame 6, and therefore the ladder-type weight 22 can push the workpiece 3 out of the sequencing frame 6 gradually. One end of the workpiece 3, which is far away from the ladder-shaped weight 22, penetrates out of the sequencing frame 6 and enters between the two limiting plates 13, and is gradually pushed out of the sequencing frame 6 along with the workpiece 3, one end of the workpiece 3, which is far away from the ladder-shaped weight 22, is in contact with the upper belt surface of the rear conveying belt 2, and the rear conveying belt 2 provides a pushing force for the workpiece 3, but at the moment, because the two limiting plates 13 limit the swinging of the workpiece 3, one end of the workpiece 3, which is far away from the ladder-shaped weight 22, is not swung after being in contact with the upper belt surface. When one end of the workpiece 3 contacting the ladder weight 22 passes over the thin pressure sensing piece 30, the workpiece 3 will not press the thin pressure sensing piece 30 any more, and the ladder weight 22 will not press the thin pressure sensing piece 30 any more, because the thin pressure sensing piece 30 is located between the two sets of rollers 42 on the side inclined surface of the ladder weight 22; after the thin pressure sensing piece 30 is not squeezed any more, the thin pressure sensing piece 30 transmits the signal without being squeezed to the control system, and the control system sets up a signal and makes an instruction for delaying the start of the electric driving module 19 for a certain time after analyzing the signal. When the ladder-shaped weight 22 completely pushes the workpiece 3 out of the sequencing frame 6, one end of the workpiece 3 close to the ladder-shaped weight 22 enters between the two limiting plates 13, and the workpiece 3 is still limited by the two limiting plates 13 and cannot swing; when the workpiece 3 is completely separated from the sorting frame 6, the workpiece 3 completely and automatically drops on the rear conveying belt 2 under the action of self gravity, and the distance between the two limiting plates 13 and the upper belt surface of the rear conveying belt 2 is greater than the height of the workpiece 3, so that the workpiece 3 is not limited by the two limiting plates 13, and the workpiece 3 is conveyed to the next procedure for sorting or packaging along with the rear conveying belt 2. When the work piece 3 does not completely slide from between two limiting plates 13, two limiting plates 13 play the effect of limit pendulum to work piece 3, prevent the work piece 3 conveying of transmission band 2 afterwards and swing, guarantee that work piece 3 can be carried with being on a parallel with back transmission band 2 bandwidth direction basically, the work piece 3 of landing on back transmission band 2 will become orderly like this, the arrangement or the packing of the next process of being convenient for very much.

After the workpiece 3 slides onto the rear conveyor belt 2, a set delay time instruction is sent out in the control system, the control system controls the electric drive module 19 to rotate reversely at the moment, the reversely rotating gear A18 drives the outer shaft 16 to rotate reversely through the gear B17, the outer shaft 16 drives the inner shaft 15 to synchronously rotate reversely through the guide block A27, the external thread on the inner shaft 15 is in threaded fit with the internal thread of the threaded sleeve, and the reversely rotating inner shaft 15 drives the sorting frame 6 to move in the rotating direction and also move obliquely downwards along the axis direction of the inner shaft 15; when the inner shaft 15 rotates reversely to drive the sorting frame 6 to rotate 180 degrees, the sorting frame 6 is restored to the initial state. In the initial state of the sequencing frame 6, the central line of the sequencing frame 6 in the length direction and the central axis of the carrier roller 4 where the front conveying belt 1 is located form an included angle of 4-6 degrees; that is to say the sorting shelf 6 is inclined; the ladder-type weight 22 will move back obliquely downward along the direction of the sequencing rack 6, the blocking block 35 will relatively enter the receiving slot 34 of the ladder-type weight 22 again, the side wall of the receiving slot 34 will press the small-angle inclined surface 41 of the blocking block 35, the design of the small-angle inclined surface 41 can make the ladder-type weight 22 easily pass over the blocking block 35, the ladder-type weight 22 presses and passes over the blocking block 35, the blocking block 35 moves toward the direction of the headed screw 38, and the spring 37 is further compressed; after the ladder-type weight 22 completely passes over the blocking block 35, the ladder-type weight 22 moves down along the sequencing frame 6 to the extreme position and stops, the blocking block 35 returns to the initial position under the reset action of the spring 37, and the large-angle inclined surface 40 of the blocking block 35 is matched with the ladder-type weight 22. Finally, the ladder-type weights 22 on the sequencing frame 6 are restored to the original positions, and the interference blocks 35 are also restored to the original positions. Then, waiting for the new workpiece 3 to be completely located in the ladder-shaped space of the sequencing frame 6 again, the new workpiece 3 presses the thin pressure sensing piece 30 again, and the control system controls the electric driving module 19 to drive the a gear 18 to operate again according to the signal sent by the thin pressure sensing piece 30, so that the sequencing of the new workpiece 3 on the rear conveying belt 2 can be completed by repeating the flow of driving the electric driving module 19 to rotate forward and backward.

The invention carries out the implementation flow of the ordered ranking work of the workpieces 3 by installing the thin pressure induction sheet 30: for the invention to use the thin pressure sensor to execute the reciprocating periodic motion, the conducting wire 25 electrically connected between the thin pressure sensor and the control system passes through the arc groove 31 and the straight groove 26 and then passes out of the outer shaft 16, and then is electrically connected with the control system, the straight groove 26 is positioned on the central axis of the inner shaft 15 and the outer shaft 16, the arc groove 31 is positioned in the middle part of the sequencing frame 6, so that the conducting wire 25 electrically connected between the thin pressure sensor and the control system can not be stretched and bent in the process of rotating the inner shaft 15, the outer shaft 16 and the sequencing frame 6, and the service life of the conducting wire 25 is prolonged.

When the conveying device carries out orderly oriented arrangement on the workpieces 3, the arrangement precision of the workpieces 3 by using high-precision equipment or a mechanical arm is possibly not high, but the conveying device is a good choice for orderly arrangement of the workpieces 3 with low cost.
