Description

Technical Field

[0001] The present invention relates to the technical field of package conveyor belt equipment, and in particular to a conveying device capable of extending a large package spacing. Background Art

[0002] In actual parcel delivery work, conveyor belts are a common delivery method. At the same time, when conveying parcels on actual conveyor belts, in order to ensure that the parcels can have a longer spacing and facilitate subsequent sorting and inspection, two conveyor belts are usually docked. Through the speed difference of the two conveyor belts, when the two conveyor belts run at different speeds, the parcels placed on the conveyor belts will produce relative displacement due to the speed difference, thereby achieving adjustment of the parcel spacing. However, the current conveying device is mainly for single-displacement parcels with fewer parcels. When there are more parcels, the dispersion spacing is limited, which is not convenient for zoned differential speed dispersion. At the same time, the traditional conveyor belt is mainly a single-piece structure. The conveyor belt is a wearing part and is not convenient for replacement without stopping the machine. The risk of replacement without stopping the driving wheel is high. Once damaged, it is necessary to stop the machine for replacement, causing the parcel to stop running. At the same time, the docking point of the traditional conveyor belt is prone to causing bagged parcels to get stuck, causing parcel blockage and damage. Summary of the invention

The transmission member of the conveying device can facilitate the staff to independently control a single driving wheel to stop and replace the conveyor belt, thereby ensuring the continuity of operation of the structure and avoiding package congestion caused by shutdown.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1 to 13 :

[0038] The present invention proposes a conveying device capable of opening a large distance between packages, comprising a grading conveying part 1, wherein two grading conveying parts 1 are provided, and the two grading conveying parts 1 are symmetrically arranged; the structures of the two grading conveying parts 1 are the same; the two grading conveying parts 1 are respectively equipped with a differential driving device 2; a diversion auxiliary part 3 is installed on the front grading conveying part 1; the diversion auxiliary part 3 is used for pushing the package; two partition driving parts 4 are respectively installed on the two grading conveying parts 1; eight transmission parts 5 are respectively installed on the two grading conveying parts 1; belt detection parts 6 are respectively installed on the eight transmission parts 5; the eight transmission parts 5 are used for lifting and lowering control transmission; an incoming goods diversion part 7 is installed on the front grading conveying part 1; the front grading conveying part 1 An anti-pinch piece 8 is installed on it; the anti-pinch piece 8 is attached to the grading conveying part 1 on the rear side; the grading conveying part 1 includes: a conveying belt frame 101, a driven wheel 1011, a conveying belt 102 and a guide wheel 103, and the side of the conveying belt frame 101 is an inclined structure; eight conveying belts 102 are sleeved on the conveying belt frame 101, and the lengths of the eight conveying belts 102 are reduced successively; eight driven wheels 1011 are rotatably installed on the inclined surface of the side of the conveying belt frame 101, and the eight driven wheels 1011 are respectively rolled and attached to the eight conveying belts 102; a guide wheel 103 is fixedly installed on the bottom of the conveying belt frame 101, and the guide wheel 103 is attached to the outside of the conveying belt 102; the eight conveying belts 102 are respectively attached to the inside of the conveying belt frame 101.

[0039] In the disclosed embodiment, the graded conveying part 1 also includes: a driving wheel 104, eight driving wheels 104 are rotatably mounted on the conveying belt frame 101, and meshing teeth are respectively provided in the middle of the eight driving wheels 104; the eight driving wheels 104 are respectively connected to eight conveying belts 102 for transmission; the differential drive device 2 includes: a differential motor 201 and a transmission belt 202, two differential motors 201 are fixedly mounted on the conveying belt frame 101, and pulleys are respectively provided on the output shafts of the two differential motors 201; the outer side of the pulleys on the output shafts of the differential motors 201 is sleeved with a transmission belt 202; the two differential motors 201 are used to control the rotation of the eight driving wheels 104; the rotation speeds of the two differential motors 201 are different; the partition driving member 4 includes: a differential transmission shaft 401 and a differential gear 402, two differential transmission shafts 401 are rotatably mounted on the conveying belt frame 101, and pulleys are respectively provided at the ends of the two differential transmission shafts 401; the pulleys at the ends of the two differential transmission shafts 401 are respectively connected to the transmission belt On the two transmission belts 202; four differential gears 402 are respectively provided on the two differential transmission shafts 401, and the differential gears 402 are respectively aligned with the meshing teeth in the middle of the driving wheel 104. The graded conveying part 1 can be used in conjunction with the partition driving part 4 to realize partition controlled conveying, which can improve the dispersed spacing conveying effect of the structure, and can be more suitable for large-scale package dispersion work. The structure has efficient conveying, and the combined use is adopted. The four differential motors 201 are used to drive the conveyor belt 102, which can better disperse the differential spacing of large quantities of packages, avoid the staggering of multiple packages in the same row, improve the convenience of subsequent sorting, and relieve the conveying pressure at the same time. The inclined structure at the docking point of the two conveyor belt frames 101 is used. After the two conveyor belt frames 101 are docked, the eight conveyor belts 102 respectively arranged on the two conveyor belt frames 101 can form a stepped staggered layer, which can prevent the cylindrical packages from rolling at the conveyor belt docking point, causing material congestion, and the structure is more reasonable, as shown in the attached figure. Fig.13 As shown: four differential motors 201 are used to drive four conveyor belts 102 for conveying respectively, and the conveying speeds are different, so that four differential partitions can be formed, namely primary drive, secondary drive, tertiary drive and quaternary drive. The conveying speed can be adopted in a decreasing manner, and can also be adjusted by the staff according to needs. When the package is on the conveyor belt 102 at the third-level drive and fourth-level drive positions, the conveying speed of the conveyor belt 102 is different, and the existence of staggered packages can assist in differential separation. Then, when entering the conveyor belt 102 at the first-level drive and second-level drive positions, the conveying speed is accelerated again, and the spacing of the packages in the moving direction is increased, thereby realizing another package dispersion spacing.

[0040] In the embodiment of the present disclosure, the diversion auxiliary component 3 includes: a diversion support frame 301, a pushing hydraulic cylinder 302, a lifting plate 303 and an air connection pipe 304. The diversion support frame 301 is fixedly installed at the bottom of the conveyor belt frame 101 on the front side by bolts; a pushing hydraulic cylinder 302 is installed on the diversion support frame 301; a lifting plate 303 is fixedly installed on the output shaft of the pushing hydraulic cylinder 302, and the lifting plate 303 is slidably inserted on the conveyor belt frame 101 on the front side; jet grooves are provided on both sides of the lifting plate 303; an air connection pipe 304 is fixedly installed on the side of the lifting plate 303; the air connection pipe 304 is externally connected to an air pump; the top of the lifting plate 303 is flush with the top surface of the conveyor belt frame 101, and the diversion auxiliary component 3 is used, mainly for larger box-type packages, which can be pushed by the air force to prevent larger and heavier packages from being in the middle of the conveyor belt frame 101 because the conveyor belt frame 101 The eight conveyor belts 102 on the conveyor belts are transported by two differential motors 201. Four conveyor belts 102 form a group, and the speeds of the two groups are different. When a package is between the two groups of conveyor belts 102, under the friction of the package's own weight, the speed of the package is likely to be unable to reach the conveying speed of the faster group of conveyor belts 102, while the smaller packages or packages completely on the conveyor belts 102 on both sides are not affected. At this time, congestion is likely to occur if the speed of the heavier packages is reduced. The use of the lifting plate 303 can cause the package to deviate to one side by lifting, thereby achieving the effect of auxiliary isolation and ensuring the smooth flow of each partition. The lifting plate 303 is driven to rise in real time by the pushing hydraulic cylinder 302, and the package can be pushed to any side. During the process, the air pump connected to the air pipe 304 supplies air, which can assist in blowing the package and provide a certain lifting wind force to facilitate the sliding of the package. The structure is simple and automatically controlled.

[0041] In the embodiment of the present disclosure, the transmission member 5 includes: a transmission connecting frame 501 and a lifting slider 502. The transmission connecting frame 501 is fixedly installed at the bottom of the conveyor belt frame 101; the lifting slider 502 is slidably installed on the transmission connecting frame 501; the transmission member 5 also includes: an electric screw rod 503 and a connecting gear 504. The electric screw rod 503 is composed of a motor and a screw rod; the motor end of the electric screw rod 503 is fixedly installed at the bottom of the transmission connecting frame 501; the screw rod end of the electric screw rod 503 rotates through the transmission connecting frame 501; a connecting gear 504 is rotatably installed on the lifting slider 502; the connecting gear 504 is meshed with the differential gear 402; the transmission member 5 can be used This allows the staff to independently control a single drive wheel to stop and replace the conveyor belt 102, ensuring the continuity of the operation of the structure and avoiding package congestion caused by shutdowns. At the same time, replacement is safer and more convenient, and can be more suitable for conveying work that requires continuous operation. By using the eight conveyor belts 102 respectively set on the two conveyor belt racks 101, when a local conveyor belt is replaced, it will not cause a significant impact on the conveying work, and the structure is more reasonable. When any conveyor belt 102 on the two conveyor belt racks 101 is damaged or needs to be replaced, the electric screw 503 is directly controlled to drive the lifting slider 502 to move downward, which can drive the connecting gear 504 to disengage from the differential gear 402.

[0042] In the embodiment of the present disclosure, the belt detection member 6 includes: a lifting connection tube 601, a spring 602, a micro switch 603, a descending column 604, a lifting hydraulic cylinder 605 and a downward pressure tightening wheel 606. The lifting connection tube 601 is fixedly installed on the transmission connection frame 501 by bolts; the lifting connection tube 601 is sleeved with a spring 602; the lifting connection tube 601 is provided with a hexagonal hole; the lifting connection tube 601 is fixedly installed with a micro switch 603; the lifting connection tube 601 is slidably plugged with a descending column 604, and the descending column 604 is a hexagonal column structure; the descending column 604 is fixedly installed with a lifting hydraulic cylinder 605, and the lifting hydraulic cylinder 60 The output shaft of 5 is attached to the micro switch 603; the spring 602 is connected between the lifting connection tube 601 and the descending column 604; the bottom of the descending column 604 is rotatably installed with a downward pressure tightening wheel 606, and the downward pressure tightening wheel 606 rolls and fits the conveyor belt 102; the incoming diverter 7 includes: an axis frame 701, a swing rod 702 and an electromagnet 703, the axis frame 701 is fixedly installed on the front conveyor belt frame 101; eight swing rods 702 are rotatably installed on the axis frame 701; the eight swing rods 702 correspond to eight conveyor belts 102 respectively; eight electromagnets 703 are fixedly installed on the axis frame 701 through a bracket; the eight electromagnets 703 are electrically connected to two conveyor belts respectively The micro switch 603 on the same side of the rack 101 uses a belt detection member 6 to facilitate the staff to control the release of the tension conveyor belt 102, which is convenient for replacing the conveyor belt 102. At the same time, the belt detection member 6 used can automatically detect the replacement of the conveyor belt 102, and can control the incoming diversion member 7 to divert the parcels at the position of replacing the detection conveyor belt 102, so that the parcels are transported to the detection conveyor belt 102 on the adjacent side, which can further alleviate the congestion pressure and reduce the potential congestion. The structure is more reasonable and automatic control can be achieved to avoid manual forgetting. Stopping the introduction of parcels at the conveyor belt 102 that needs to be replaced is also convenient for replacing the conveyor belt 102 and controlling the lifting of the corresponding side. The lowering hydraulic cylinder 605 contracts, driving the lowering column 604 to move upward, which can drive the downward pressure tightening wheel 606 to release the squeezing of the conveyor belt 102. After the lowering column 604 rises, it is no longer relatively squeezed by the conveyor belt 102. Under the squeezing of the spring 602, the spring 602 squeezes the lifting hydraulic cylinder 605. At this time, the end of the lifting hydraulic cylinder 605 no longer squeezes the microswitch 603. The microswitch 603 is powered off to control the electromagnet 703 to be powered off, and the swing rod 702 is no longer magnetically attracted. The swing rod 702 naturally rotates and falls, and the feed point on one side of the conveyor belt 102 that needs to be replaced can be blocked. At this time, the connecting buckle position of the conveyor belt 102 can be found for disassembly and replacement.

[0043] Embodiment 2, on the basis of embodiment 1, the anti-clamping member 8 comprises: an anti-clamping shell 801 and an air nozzle 802, the anti-clamping shell 801 is fixedly mounted on the front conveyor belt frame 101; eight air nozzles 802 are fixedly mounted on the anti-clamping shell 801, and the eight air nozzles 802 are respectively attached to the conveyor belts 102 on the two conveyor belt frames 101; the anti-clamping shell 801 is externally connected to a fan; the air nozzle 802 is used to blow air to prevent the anti-clamping package, and the anti-clamping member 8 can be used to automatically pass the wind force to prevent the package from being stuck in the adjacent conveyor belt frame 101 at the joint of the two conveyor belt frames 101 during the conveying process. The belt 102 does not cause jamming, and the structure is more reasonable, which can improve practicality, optimize the current conveyor belt structure, and improve safety. The wind blowing method will not cause safety hazards. During the package transportation process, when the package is transported on the conveyor belt 102, the fan external to the anti-pinch shell 801 starts to exhaust air in real time, and controls the air nozzle 802 to spray. At this time, when the package passes through the air nozzle 802, the bag package will not be stuck. There is no need to use plastic baskets to carry out transportation like traditional bag packages. It is more convenient and reduces the workload of package transportation preparation.

[0044] The working principle of this embodiment is as follows: first, after the two conveyor belt frames 101 are docked, they are placed on the ground and installed on the ground with bolts, and the four differential motors 201 are controlled to be energized for conveying. After the package is placed on the front conveyor belt frame 101 by a package slide or manually, the differential motor 201 drives the transmission belt 202 to drive and control the differential transmission shaft 401 to rotate, and then the differential gear 402 engages with the connecting gear 504 to drive the guide wheel 103 to rotate, so as to drive the conveyor belt 102 to carry out conveying work, as shown in the attached figure. Fig.13 As shown: when the package is on the conveyor belt 102 at the third-level drive and fourth-level drive positions, the conveying speed of the conveyor belt 102 is different, and the existence of staggered packages can assist in differential separation. Then, when the package enters the conveyor belt 102 at the first-level drive and second-level drive positions, the speed is accelerated again, and the spacing of the packages in the moving direction is increased, so that the package dispersion spacing is achieved again. During the package transportation process, the fan connected to the anti-clamp shell 801 is started to exhaust air in real time, and the air nozzle 802 is controlled to spray air. At this time, when the package passes through the air nozzle 802, the bag package will not be stuck. The lifting plate 303 is driven to rise in real time by the pushing hydraulic cylinder 302, and the package can be pushed to any side. During the process, the air pump connected to the air pipe 304 is used to supply air, which can assist in blowing the package and provide a certain lifting wind force to facilitate the sliding of the package.

[0045] When any one of the conveyor belts 102 on the two conveyor belt frames 101 is damaged or needs to be replaced, the electric screw rod 503 is directly controlled to drive the lifting slider 502 to move downward, which can drive the connecting gear 504 to disengage from the differential gear 402. At this time, the driving wheel 104 on the corresponding side loses the power source and will stop rotating. The staff can quickly replace the conveyor belt 102. During the process, the differential motor 201 does not need to be stopped, and the normally operating conveyor belt 102 can be used for transportation; after the driving wheel 104 stops rotating, the lifting hydraulic cylinder 605 on the corresponding side can be controlled to contract, driving the descending column 604 to move upward, which can drive the downward pressure tightening wheel 606 to release the squeezing of the conveyor belt 102. After the descending column 604 rises, it is no longer relatively squeezed by the conveyor belt 102. Under the squeezing of the spring 602, the spring 602 squeezes the lifting hydraulic cylinder 605. 05. At this time, the end of the lifting hydraulic cylinder 605 no longer squeezes the micro switch 603. The micro switch 603 is powered off to control the electromagnet 703 to be powered off, and the swing rod 702 is no longer magnetically attracted. The swing rod 702 rotates and falls naturally, and the feeding point on one side of the conveyor belt 102 that needs to be replaced can be covered. At this time, the connecting buckle position of the conveyor belt 102 can be found for disassembly and replacement, and then the descending column 604 is controlled to descend, and the downward pressure tensioning wheel 606 is controlled to tighten the new conveyor belt 102. At this time, the micro switch 603 is squeezed and fitted by the lifting hydraulic cylinder 605 again, and the electromagnet 703 is controlled to be energized. After the swing rod 702 is manually lifted, the electromagnet 703 is magnetically attracted, and then the lifting slider 502 is controlled to rise, driving the connecting gear 504 to move up, meshing the differential gear 402 and the driving wheel 104, and the conveying work can be resumed.
