Sorting device for sorting according to volume and use method thereof

Abstract

The present invention relates to the field of express delivery sorting. The present invention discloses a sorting device for sorting according to volume and a method for use. The problem to be solved by the present invention is that the existing equipment usually causes the packages to be blocked during the conveying process when screening the packages according to their volume, thereby affecting the entire conveyor line. In addition, the volume screening of the packages on a conveyor line is relatively single and it is impossible to screen packages of different volumes one by one, resulting in a poor volume screening effect. The present invention can screen packages of different volumes by setting up multiple groups of screening devices, thereby screening the packages on the conveyor belt from large to small in sequence, making it convenient for operators to collect and process packages of different volumes.

[0010] Preferably, a pushing frame is hingedly provided on the supporting frame, and the pushing frame is located above the circular opening. The other end of the resisting rod is rotatably provided with a hinged frame, and the hinged frame is hingedly matched with the pushing frame.

[0011] Preferably, the method for using the sorting device for sorting according to volume size comprises the following steps:

[0012] S1: When the parcel needs to be transported and sorted by the conveyor belt, the operator places the parcel on the conveyor belt, and the parcel moves toward the receiving box through the guide roller under the transportation of the conveyor belt. When the parcel passes the guide roller, the guide roller can trim the parcel so that the parcel is on the same horizontal axis as the screening channel when it is transported on the conveyor belt to the screening device. When the parcel is transported to the two barrier rollers, the smaller parcel will directly pass through the screening channel and continue to be transported to the next group of screening devices for volume screening, while the larger parcel cannot pass through the two barrier rollers and is blocked by the two barrier rollers. After the two barrier rollers block the larger parcel, the push cylinder will drive the push plate to move and move the larger parcel toward the circular opening on the screening element, and the larger parcel will be screened through the provided circular opening. Arranging multiple groups of screening devices on the conveyor belt can screen parcels of different volumes, so that the parcels on the conveyor belt can be screened in order from large to small, which is convenient for the operator to collect and process parcels of different volumes;

[0013] S2: When a larger parcel is pushed by the push plate to the circular opening on the support seat, if the parcel is just in the center of the circular opening, the parcel will fall directly into the circular opening and then fall into the receiving compartment for collection and processing. If the parcel fails to reach the center of the circular opening when being pushed by the push plate, the parcel will remain on the support seat. At this time, the swing device needs to move the parcel retained on the support seat so that the parcel can effectively fall into the circular opening;

[0014] S3: When the package is pushed onto the supporting seat by the pushing plate, the side wall of the package will contact the clamping plate, and the clamping plate will limit the package under the pressure of the two extrusion springs. Then the rotating motor drives the rotating rod to rotate, and the rotating rod causes the rotating block to rotate. Because the other end of the rotating block is tilted, when the rotating block rotates, the other end of the rotating block drives the swing column to swing obliquely. When the swing column swings, the limiting swing frame limits the swing column. The swinging of the swing column drives the swing disk to swing. The swinging of the swing disk drives the set clamping member to swing, so that the clamped package is continuously tilted at the circular opening, thereby adjusting the position of the package so that the package can effectively fall into the circular opening. This setting effectively solves the problem that the package cannot be aligned with the circular opening for unloading, thereby avoiding the phenomenon of the package being stuck on the supporting seat and causing material blockage, and improves the efficiency of package volume screening;

[0015] S4: When the rotating rod drives the rotating block to adjust the position of the package, the rotating rod rotates to drive the rotating disk to rotate. The rotating disk rotates the annular slide rail and contacts the sliding rod. At this time, the initial state of the arc frame is that the inner arc of the arc frame coincides with the outer arc angle of the annular slide rail. The arc frame contacts the first gear rod under the action of the tension spring. When the rotating disk rotates one circle, the sliding rod moves in the annular slide rail and contacts the end of the arc frame. When the end of the arc frame contacts the sliding rod When the rotating disk rotates to the second circle, the sliding rod will contact the outer wall of the arc frame when it moves in the annular slide rail, and the sliding rod will drive the interference rod to move forward in the limit seat. The movement of the interference rod will drive the articulated frame to deflect the push frame toward the direction of the circular opening. If the package does not fall into the circular opening after rotating two circles under the position adjustment of the swing device, the diameter of the circular opening is smaller than the diameter of the package. At this time, the pushing frame will push the package remaining on the supporting seat to the conveyor belt under the drive of the resistance rod, and then the packages that do not meet the standards will be transported and separated through the conveyor belt. This setting solves the problem that if the diameter of the package is larger than the diameter of the circular opening, it cannot be unloaded. Adjustments are made to the accidental volume screening during the package sorting process. The rotating part rotates two weeks before screening the packages that do not meet the volume, giving the swing device time to adjust the position of the package, reducing the error rate during the screening process. When the pushing frame transfers the package to the conveyor belt, the sliding rod moves to the end of the arc frame, causing the arc frame to deflect on the rotating disk, causing the arc frame to contact the first gear rod and then reset the arc frame. At the same time, the elastic spring will drive the resistance rod to reset, so that it can still cope with the situation where the package does not correspond to the circular opening next time.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the package is transported to the screening device, the guide roller can trim the package so that the package is on the same transverse axis as the screening channel when it is transported to the screening device on the conveyor belt. When the package is transported to the two isolation rollers, the smaller package will directly pass through the screening channel and continue to be transported to the next group of screening devices for volume screening, while the larger package cannot pass through the two isolation rollers and is blocked by the two isolation rollers. After the two isolation rollers block the larger package, the pushing electric cylinder will drive the pushing plate to move and move the larger package toward the circular opening on the screening element, and the larger package will be screened through the provided circular opening. Arranging multiple groups of screening devices on the conveyor belt can screen packages of different volumes, so that the packages on the conveyor belt can be screened in order from large to small, which is convenient for the operator to collect and process packages of different volumes.

[0018] In the present invention, when a larger package is pushed to the circular opening on the supporting seat by the pushing plate, if the pushed package is exactly in the center of the circular opening, the package will directly fall into the circular opening, and then fall into the receiving compartment to collect and process the larger package. If the package fails to be pushed to the center of the circular opening when being pushed by the pushing plate, the package will remain on the supporting seat. At this time, the swing device is required to move the package retained on the supporting seat so that the package can effectively fall into the circular opening.

[0019] In the present invention, when the package is pushed onto the supporting seat by the pushing plate, the side wall of the package will contact the clamping plate, and the clamping plate will limit the package under the pressure of two extrusion springs. Then the rotating motor drives the rotating rod to rotate, and the rotating rod causes the rotating block to rotate. Because the other end of the rotating block is tilted, when the rotating block rotates, the other end of the rotating block will drive the swing column to swing obliquely. When the swing column swings, the limiting swing frame limits the swing column. The swinging of the swing column will drive the swing disk to swing. The swinging of the swing disk will drive the set clamping part to swing, so that the clamped package will continue to tilt at the circular opening, thereby adjusting the position of the package so that the package can effectively fall into the circular opening. This arrangement effectively solves the problem that the package cannot be aligned with the circular opening for unloading, thereby avoiding the phenomenon of package being stuck on the supporting seat and causing material blockage, and improves the efficiency of package volume screening.

[0020] In the present invention, when the rotating rod drives the rotating block to adjust the position of the swing plate to the package, the rotating rod rotates to drive the rotating plate to rotate, and the rotating plate rotates the annular slide rail to contact the sliding rod. At this time, the initial state of the arc frame is that the inner wall arc of the arc frame coincides with the outer wall arc angle of the annular slide rail. The arc frame contacts the first gear rod under the action of the tension spring. When the rotating plate rotates one circle, the sliding rod moves in the annular slide rail and contacts the end of the arc frame. When the end of the arc frame contacts the sliding rod When the rotating disk is rotated to the second circle, the sliding rod will contact the outer wall of the arc frame when it moves in the annular slide rail, and the sliding rod will drive the resistance rod to move forward in the limit seat. The movement of the resistance rod will drive the articulated frame to deflect the push frame toward the direction of the circular opening. If the package does not fall into the circular opening after rotating two circles under the position adjustment of the swing device, the diameter of the circular opening is smaller than the diameter of the package. At this time, the pushing frame will push the package remaining on the supporting seat to the conveyor belt under the drive of the resistance rod, and then the packages that do not meet the standards will be transported and separated through the conveyor belt. This setting solves the problem that if the diameter of the package is larger than the diameter of the circular opening, it cannot be unloaded. Adjustments are made to the accidental volume screening during the package sorting process. The rotating part rotates two weeks before screening the packages that do not meet the volume, giving the swing device time to adjust the position of the package, reducing the error rate in the screening process. When the pushing frame transfers the package to the conveyor belt, the sliding rod moves to the end of the arc frame, causing the arc frame to deflect on the rotating disk, causing the arc frame to contact the first gear rod and then reset the arc frame. At the same time, the elastic spring will drive the resistance rod to reset, so that it can still cope with the situation that the package does not correspond to the circular opening next time.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] See also Figures 1 to 9 The present invention provides a technical solution: a sorting device for sorting according to volume size, comprising a carrying platform 1 placed horizontally on the ground, a conveyor belt 11 for transporting express items provided on the top of the carrying platform 1, a plurality of screening devices 2 arranged at equal intervals provided on the carrying platform 1, and the plurality of screening devices 2 are located beside the conveyor belt 11, the carrying platform 1 is further provided with a plurality of guide rollers 12 arranged opposite to each other, and the plurality of guide rollers 12 arranged opposite to each other are all located beside the conveyor belt 11, a material receiving box 13 is further placed on the carrying platform 1, and the movement direction of the conveyor belt 11 starts from one side of the guide roller 12 and moves toward the material receiving box 13.

[0033] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, several of the screening devices 2 include a support frame 21, a pushing electric cylinder 22, a pushing plate 23 and two spacer rollers 24. The support frame 21 is fixedly arranged on the top of the carrier platform 1. The two spacer rollers 24 are relatively rotatably arranged on the support frame 21, and the two spacer rollers 24 are located above the conveyor belt 11. The gap between the two spacer rollers 24 constitutes a screening channel 25. The diameter of the screening channel 25 of several of the screening devices 2 gradually decreases in the direction from the guide roller 12 to the material receiving box 13. The pushing electric cylinder 22 is fixedly arranged on the top of the carrier platform 1, and the pushing plate 23 is arranged on the telescopic end of the pushing electric cylinder 22 and is located beside the spacer roller 24 of the carrier platform 1.

[0034] When the parcel needs to be transported and sorted by the conveyor belt 11, the operator places the parcel on the conveyor belt 11, and the parcel passes through the guide roller 12 under the conveyance of the conveyor belt 11 and moves toward the receiving box 13. When the parcel passes through the guide roller 12, the guide roller 12 can trim the parcel so that the parcel is on the same horizontal axis as the screening channel 25 when it is transported to the screening device 2 on the conveyor belt 11. When the parcel is transported to the two isolation rollers 24, the smaller parcel will directly pass through the screening channel 25 and continue to be transported to the next group of screening devices 2 for volume screening, while the larger parcel will not be The method is to pass through the two isolation rollers 24 and be blocked by the two isolation rollers 24. After the two isolation rollers 24 block the larger package, the pushing electric cylinder 22 will drive the pushing plate 23 to move and thus move the larger package toward the circular opening 311 on the screening element 3. The larger package is screened through the provided circular opening 311. Multiple groups of screening devices 2 are set on the conveyor belt 11 to screen packages of different volumes, thereby screening the packages on the conveyor belt 11 in order from large to small, making it convenient for operators to collect and process packages of different volumes.

[0035] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 Some of the screening devices 2 are further provided with a screening element 3, which includes a bearing seat 31, a conveyor belt 32 and a material receiving compartment 33. The bearing seat 31 is fixedly arranged on the top of the bearing platform 1, and a circular opening 311 is opened on the bearing seat 31, and the circular opening 311 passes through the bearing platform 1. The diameter of the circular opening 311 is larger than the diameter of the screening channel 25 on the corresponding same group of screening devices 2. The material receiving compartment 33 is fixedly arranged on the bearing platform 1 and is located below the circular opening 311. The conveyor belt 32 is arranged on the bearing seat 31 and is located next to the circular opening 311.

[0036] When a larger package is pushed to the circular opening 311 on the supporting seat 31 by the pushing plate 23, if the pushed package is exactly at the center of the circular opening 311, the package will directly fall into the circular opening 311 and then fall into the receiving compartment 33 to collect and process the larger packages. If the package fails to reach the center of the circular opening 311 when being pushed toward the circular opening 311 by the pushing plate 23, the package will remain on the supporting seat 31. At this time, the swing device 4 needs to move the package retained on the supporting seat 31 so that the package can effectively fall into the circular opening 311.

[0037] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The support frame 31 is further fixedly provided with a support frame 34 at the top of the circular opening 311 on the support seat 31, and a swing device 4 is provided on the support frame 34. The swing device 4 includes a rotating motor 41, a rotating rod 42, a rotating block 43, a swing column 44, a swing plate 45 and a limited swing frame 46. The rotating motor 41 is fixedly provided on the top of the support frame 34, the rotating rod 42 is provided on the main shaft of the rotating motor 41, and the rotating rod 42 is rotatably matched with the support frame 34, one end of the rotating block 43 is fixedly provided on the rotating rod 42, and the other end of the rotating block 43 is inclined. The axis of the swing column 44 is provided at an end of the inclined rotating rod 42, and the limited swing frame 46 is rectangular. One side outer wall of the limited swing frame 46 is rotatably matched with the support frame 34, and the other side outer wall of the limited swing frame 46 is rotatably matched with the outer wall of the swing column 44. The swing plate 45 is fixedly provided on the end surface of the swing column 44 and is arranged in the direction of the circular opening 311;

[0038] The swing plate 45 is further provided with a clamping member 5 arranged opposite to each other. The clamping member 5 includes a connecting frame 51, a clamping plate 52, two connecting rods 53 and two extrusion springs 54. The connecting frame 51 is fixedly arranged at the bottom of the swing plate 45 and is arranged in the direction of the circular opening 311. The two connecting rods 53 are relatively slidably arranged on the connecting frame 51. The clamping plate 52 is fixedly connected to one end of the two connecting rods 53. The two extrusion springs 54 are respectively sleeved on the two connecting rods 53, and the two ends of the extrusion springs 54 are respectively connected to the connecting frame 51 and the clamping plate 52.

[0039] When the package is pushed onto the supporting seat 31 by the pushing plate 23, the side wall of the package will contact the clamping plate 52, and the clamping plate 52 will limit the package under the pressure of the two extrusion springs 54. Then the rotating motor 41 drives the rotating rod 42 to rotate, and the rotating rod 42 causes the rotating block 43 to rotate. Because the other end of the rotating block 43 is tilted, when the rotating block 43 rotates, the other end of the rotating block 43 drives the swing column 44 to swing obliquely. When the swing column 44 swings, the limiting swing frame 46 limits the swing column 44. The swing of the swing column 44 drives the swing plate 45 to swing. The swing of the swing plate 45 drives the set clamping member 5 to swing, so that the clamped package is continuously tilted at the circular opening 311, thereby adjusting the position of the package so that the package can effectively fall into the circular opening 311. This arrangement effectively solves the problem that the package cannot be aligned with the circular opening 311 for unloading, thereby avoiding the phenomenon of the package being stuck on the supporting seat 31 and causing material blockage, and improves the efficiency of package volume screening.

[0040] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, a rotating member 6 is further provided on the top of the carrier 34, and the rotating member 6 includes a rotating disk 61, an arc frame 64, a clamping rod 65, a tension spring 66, a limit seat 67, a sliding rod 68, a contact rod 69 and an elastic spring 691. The rotating disk 61 is fixedly arranged on the rotating rod 42, and an annular slide rail 611 is provided on the surface of the rotating disk 61. The clamping rod 65 is rotatably arranged on the rotating disk 61, and the arc frame 64 is fixedly arranged on the top of the clamping rod 65. The inner wall arc angle of the arc frame 64 is the same as the outer wall arc angle of the annular slide rail 611. When the inner wall arc angle of the arc frame 64 coincides with the arc angle of the annular slide rail 611, the tail end of the arc frame 64 is located in the annular slide rail 611, and the outer wall arc angle of the arc frame 64 coincides with the outer wall arc angle of the annular slide rail 611. The inner arc angles are the same, and the two ends of the tension spring 66 are respectively connected to the card rod 65 and the rotating disk 61. The rotating disk 61 is also fixed with a first gear rod 62 and a second gear rod 63. The first gear rod 62 and the second gear rod are respectively located on both sides of the annular slide rail 611 and conflict with the arc frame 64. The limit seat 67 is fixedly set on the top of the carrier 34. A slide groove is opened in the limit seat 67. The interference rod 69 slides with the slide groove on the limit seat 67. The sliding rod 68 is fixedly set at one end of the interference rod 69 and slides with the annular slide rail 611. The sliding rod 68 conflicts with the arc frame 64. The elastic spring 691 is sleeved on the interference rod 69 and the two ends of the elastic spring 691 are respectively connected to the interference rod 69 and the inner wall of the slide groove;

[0041] The carrier frame 34 is further hingedly provided with a push frame 7, which is located above the circular opening 311. The other end of the abutment rod 69 is rotatably provided with a hinge frame 71, which is hingedly matched with the push frame 7.

[0042] When the rotating rod 42 drives the rotating block 43 to adjust the position of the package, the rotating rod 42 rotates to drive the rotating disk 61 to rotate, and the rotating disk 61 rotates the annular slide rail 611 to contact the sliding rod 68. At this time, the initial state of the arc frame 64 is that the inner wall arc of the arc frame 64 coincides with the outer arc angle of the annular slide rail 611. The arc frame 64 contacts the first gear rod 62 under the action of the tension spring 66. When the rotating disk 61 rotates one circle, the sliding rod 68 moves in the annular slide rail 611 and contacts the end of the arc frame 64. When the end of the arc frame 64 When the sliding rod 68 contacts the arc frame 64, the arc frame 64 will be deflected on the rotating disk 61 through the card rod 65, and the tension spring 66 will make the arc frame 64 contact the second gear rod 63. At this time, the arc angle of the outer wall of the arc frame 64 will be the same as the inner arc angle of the annular slide rail 611. Then, when the rotating disk 61 rotates to the second circle, the sliding rod 68 will contact the outer wall of the arc frame 64 when moving in the annular slide rail 611. When the sliding rod 68 contacts the outer wall of the arc frame 64, it will drive the interference rod 69 to move forward in the limit seat 67. The movement of the interference rod 69 will drive the articulated frame 71 to The pushing frame 7 deflects toward the circular opening 311. If the package does not fall into the circular opening 311 after rotating twice under the position adjustment of the swing device 4, the diameter of the circular opening 311 is smaller than the diameter of the package. At this time, the pushing frame 7 will push the package remaining on the supporting seat 31 to the conveyor belt 32 under the drive of the resistance rod 69, and then the packages that do not meet the standards will be transported and separated by the conveyor belt 32. This setting solves the problem that if the diameter of the package is larger than the diameter of the circular opening 311, it cannot be unloaded, and addresses the accidental volume screening during the package sorting process. Adjustments are made, and the packages that do not meet the volume are screened after the rotating part 6 rotates two weeks, which gives the swing device 4 time to adjust the position of the package, reducing the error rate in the screening process. When the push frame 7 transfers the package to the conveyor belt 32, the sliding rod 68 moves to the end of the arc frame 64, which will deflect the arc frame 64 on the rotating disk 61, causing the arc frame 64 to contact the first gear rod 62 and then reset the arc frame 64. At the same time, the elastic spring 691 will drive the resistance rod 69 to reset, so that it can still cope with the situation that the package does not correspond to the circular opening 311 next time.

[0043] The use method and advantages of the present invention: The use method of the sorting device for sorting according to volume size, the working process is as follows:

[0044] like Figure 1、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown:

[0045] S1: When the parcel needs to be transported and sorted by the conveyor belt 11, the operator places the parcel on the conveyor belt 11. The parcel passes through the guide roller 12 under the conveyor belt 11 and moves toward the receiving box 13. When the parcel passes through the guide roller 12, the guide roller 12 can trim the parcel so that the parcel is on the same horizontal axis as the screening channel 25 when it is transported to the screening device 2 on the conveyor belt 11. When the parcel is transported to the two isolation rollers 24, the smaller parcel will directly pass through the screening channel 25 and continue to be transported to the next group of screening devices 2 for volume screening, while the larger parcel will be transported to the next group of screening devices 2 for volume screening. The larger parcel cannot pass through the two isolation rollers 24 and is blocked by the two isolation rollers 24. After the two isolation rollers 24 block the larger parcel, the pushing electric cylinder 22 drives the pushing plate 23 to move and thereby moves the larger parcel toward the circular opening 311 on the screening member 3. The larger parcel is screened through the provided circular opening 311. Arranging multiple groups of screening devices 2 on the conveyor belt 11 can screen parcels of different sizes, thereby screening the parcels on the conveyor belt 11 in order from large to small, making it convenient for the operator to collect and process parcels of different sizes.

[0046] S2: When a larger parcel is pushed by the pushing plate 23 to the circular opening 311 on the supporting seat 31, if the pushed parcel is exactly at the center of the circular opening 311, the parcel will directly fall into the circular opening 311 and then fall into the receiving compartment 33 for collection and processing of the larger parcels. If the parcel fails to reach the center of the circular opening 311 when being pushed by the pushing plate 23, the parcel will remain on the supporting seat 31. In this case, the swing device 4 needs to move the parcel retained on the supporting seat 31 so that the parcel can effectively fall into the circular opening 311.

[0047] When the package is pushed onto the supporting seat 31 by the pushing plate 23, the side wall of the package will contact the clamping plate 52, and the clamping plate 52 will limit the package under the pressure of the two extrusion springs 54. Then the rotating motor 41 drives the rotating rod 42 to rotate, and the rotating rod 42 causes the rotating block 43 to rotate. Because the other end of the rotating block 43 is tilted, when the rotating block 43 rotates, the other end of the rotating block 43 drives the swing column 44 to swing obliquely. When the swing column 44 swings, the limiting swing frame 46 limits the swing column 44. The swing of the swing column 44 drives the swing plate 45 to swing. The swing of the swing plate 45 drives the clamping member 5 to swing, so that the clamped package is continuously tilted at the circular opening 311, thereby adjusting the position of the package so that the package can effectively fall into the circular opening 311. This arrangement effectively solves the problem that the package cannot be aligned with the circular opening 311 for unloading, thereby avoiding the phenomenon of the package being stuck on the supporting seat 31 and causing material blockage, and improves the efficiency of package volume screening;

[0048] S4: When the rotating rod 42 drives the rotating block 43 to adjust the position of the package, the rotating rod 42 rotates to drive the rotating disk 61 to rotate, and the rotating disk 61 rotates the annular slide rail 611 to contact the sliding rod 68. At this time, the initial state of the arc frame 64 is that the inner wall arc of the arc frame 64 coincides with the outer arc angle of the annular slide rail 611. The arc frame 64 contacts the first gear rod 62 under the action of the tension spring 66. When the rotating disk 61 rotates one circle, the sliding rod 68 moves in the annular slide rail 611 and contacts the end of the arc frame 64. When the end contacts the sliding rod 68, the arc frame 64 will be deflected on the rotating disk 61 through the clamping rod 65, and the tension spring 66 will make the arc frame 64 contact the second gear rod 63. At this time, the arc angle of the outer wall of the arc frame 64 will be the same as the inner arc angle of the annular slide rail 611. Then, when the rotating disk 61 rotates to the second circle, the sliding rod 68 will contact the outer wall of the arc frame 64 when moving in the annular slide rail 611. When the sliding rod 68 contacts the outer wall of the arc frame 64, it will drive the interference rod 69 to move forward in the limit seat 67. The movement of the interference rod 69 will drive the articulated frame 7 1 causes the pushing frame 7 to deflect toward the circular opening 311. If the package does not fall into the circular opening 311 after rotating twice under the position adjustment of the swing device 4, the diameter of the circular opening 311 is smaller than the diameter of the package. At this time, the pushing frame 7 will push the package remaining on the supporting seat 31 onto the conveyor belt 32 under the drive of the resistance rod 69, and then the package that does not meet the standards will be transported and separated by the conveyor belt 32. This arrangement solves the problem that the package cannot be unloaded if its diameter is larger than the diameter of the circular opening 311, and solves the accidental volume screening during the package sorting process. The package that does not meet the volume requirement is adjusted after the rotating part 6 rotates two weeks, which gives the swing device 4 time to adjust the position of the package, reducing the error rate in the screening process. When the push frame 7 transfers the package to the conveyor belt 32, the sliding rod 68 moves to the end of the arc frame 64, which will deflect the arc frame 64 on the rotating disk 61, causing the arc frame 64 to contact the first gear rod 62 and then reset the arc frame 64. At the same time, the elastic spring 691 will drive the resistance rod 69 to reset, so that it can still cope with the situation that the package does not correspond to the circular opening 311 next time.

6. A method for using a sorting device for sorting by volume, comprising the following steps: S1: When the parcel needs to be transported and sorted by the conveyor belt (11), the operator places the parcel on the conveyor belt (11). The parcel moves toward the receiving box (13) through the guide roller (12) under the conveyance of the conveyor belt (11). The guide roller (12) can trim the parcel when the parcel passes through the guide roller (12) so that the parcel is on the same horizontal axis as the screening channel (25) when it is transported to the screening device (2) on the conveyor belt (11). When the parcel is transported to the two isolation rollers (24), the smaller parcel will directly pass through the screening channel (25) and continue to be transported to the next group of screening devices (2) for volume screening, while the larger parcel will be The parcel cannot pass through the two isolation rollers (24) and is blocked by the two isolation rollers (24). After the two isolation rollers (24) block the larger parcel, the electric cylinder (22) drives the push plate (23) to move and thus moves the larger parcel toward the circular opening (311) on the screening member (3). The larger parcel is screened through the provided circular opening (311). Multiple sets of screening devices (2) are provided on the conveyor belt (11) to screen parcels of different volumes, thereby screening the parcels on the conveyor belt (11) in descending order, making it convenient for operators to collect and process parcels of different volumes. S2: When a larger package is pushed by the push plate (23) to the circular opening (311) on the support seat (31), if the pushed package is just at the center of the circular opening (311), the package will directly fall into the circular opening (311) and then fall into the receiving compartment (33) to collect and process the larger package. If the package fails to reach the center of the circular opening (311) when being pushed by the push plate (23), the package will remain on the support seat (31). At this time, the swing device (4) needs to move the package retained on the support seat (31) so that the package can effectively fall into the circular opening (311); S3: When the package is pushed onto the supporting seat (31) by the pushing plate (23), the side wall of the package will contact the clamping plate (52), and the clamping plate (52) will limit the package under the pressure of the two extrusion springs (54). Then the rotating motor (41) drives the rotating rod (42) to rotate, and the rotating rod (42) causes the rotating block (43) to rotate. Because the other end of the rotating block (43) is tilted, when the rotating block (43) rotates, the other end of the rotating block (43) drives the swing column (44) to swing obliquely. When the swing column (44) swings, the limited swing frame (46) limits the swing column (44), and the swing of the swing column (44) drives the swing plate (45) to swing, and the swing of the swing plate (45) drives the clamping member (5) to swing, so that the clamped package is continuously tilted at the circular opening (311) and the position of the package is adjusted so that the package can effectively fall into the circular opening (311). This setting effectively solves the problem that the package cannot be aligned with the circular opening (311) for unloading, thereby avoiding the phenomenon of the package being stuck on the supporting seat (31) and causing material blocking, and improves the efficiency of package volume screening; S4: When the rotating rod (42) drives the rotating block (43) to adjust the position of the package by the swinging plate (45), the rotating rod (42) rotates and drives the rotating plate (61) to rotate. The rotating plate (61) rotates the annular slide rail (611) and contacts the sliding rod (68). At this time, the initial state of the arc frame (64) is that the inner wall arc of the arc frame (64) and the outer arc angle of the annular slide rail (611) coincide with each other. The arc frame (64) contacts the first gear rod (62) under the action of the tension spring (66). When the rotating plate (61) rotates one circle, the sliding rod (68) moves in the annular slide rail (611) and contacts the end of the arc frame (64). When the arc frame (64) rotates one circle, the sliding rod (68) moves in the annular slide rail (611) and contacts the end of the arc frame (64). When the end of the arc frame (64) contacts the sliding rod (68), the arc frame (64) is deflected on the rotating disk (61) through the clamping rod (65), and the tension spring (66) causes the arc frame (64) to contact the second gear rod (63). At this time, the outer wall arc angle of the arc frame (64) is the same as the inner arc angle of the annular slide rail (611). When the rotating disk (61) rotates to the second circle, the sliding rod (68) moves in the annular slide rail (611) and contacts the outer wall of the arc frame (64). When the sliding rod (68) contacts the outer wall of the arc frame (64), the resistance rod (69) is driven to move forward in the limit seat (67). The resistance rod (69) ) moves, which drives the hinged frame (71) to deflect the push frame (7) toward the circular opening (311). If the package does not fall into the circular opening (311) after rotating twice under the position adjustment of the swing device (4), the diameter of the circular opening (311) is smaller than the diameter of the package. At this time, the push frame (7) will push the package resting on the supporting seat (31) to the conveyor belt (32) under the drive of the resistance rod (69), and then the package that does not meet the standards will be transported and separated by the conveyor belt (32). This setting solves the problem that the package cannot be unloaded if its diameter is larger than the diameter of the circular opening (311). It is aimed at the volume screening during the package sorting process. The accidental adjustment is made, and the packages that do not meet the volume are screened after the rotating member (6) rotates two weeks, giving the swing device (4) time to adjust the position of the package, reducing the error rate in the screening process. When the push frame (7) transfers the package to the conveyor belt (32), the sliding rod (68) moves to the end of the arc frame (64), which will cause the arc frame (64) to deflect on the rotating disk (61), causing the arc frame (64) to contact the first gear rod (62) and then reset the arc frame (64). At the same time, the elastic spring (691) will drive the resistance rod (69) to reset, so that it can still cope with the situation that the package does not correspond to the circular opening (311) next time.
