Description

Technical Field

[0001] The present invention relates to the field of transmission and conveying technology, and in particular to a linear transmission and conveying mechanism for logistics sorting. Background Art

[0002] Logistics sorting refers to the operation of stacking items according to their types and the order of entry and exit. With the popularization of healthy eating concepts and consumers' increasing requirements for food safety and freshness, especially in the process of urbanization, office workers find it difficult to buy fresh vegetables in person due to time constraints, making vegetable logistics sorting and delivery in the same city more and more common.

[0003] Currently, when sorting vegetables, the information of the vegetables to be sorted is obtained according to the customer's order, and a sorting plan is formulated. However, when sorting spherical vegetables such as tomatoes, onions and potatoes, during the period of high order demand, the sorting personnel in the vegetable sorting center are relatively busy, and there are many vegetables on the sorting conveyor belt, which can easily cause the spherical vegetables to roll, collide and squeeze each other, causing the vegetables to be damaged during the logistics sorting process. In addition, the vegetables are all in a single state, and the logistics sorting of vegetables is mostly based on the weight of the customer's order. In order to avoid the situation of short weight, it is necessary to continuously adjust the weighed vegetables, which reduces the subsequent sorting and packaging efficiency. At the same time, the vegetables are constantly replaced and adjusted during the weighing process, which can easily lead to confusion in the sorting and weighing area. Therefore, a linear transmission conveying mechanism for logistics sorting is proposed. Summary of the invention

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example, see Figures 1 to 7 A linear transmission conveying mechanism for logistics sorting includes a conveying platform 1 and a conveyor belt 2 for logistics sorting vegetables. A dispersion box 4 filled with clean water is fixedly connected to the top of the conveying platform 1. An obliquely arranged dumping hole plate 6 is fixedly connected to the inner end surface of the dispersion box 4 through a plurality of hydraulic push rods 5. A side wall of the dispersion box 4 located on one side of the conveyor belt 2 is connected to a sliding plate 8. The left and right side walls of the sliding plate 8 are both connected to side baffles 9. A guide buffer component for buffering the sliding vegetables is arranged between the two side baffles 9.

[0031] Furthermore, the top of the conveying platform 1 is connected to the inner wall of the conveyor belt 2 through the support frame 3, the dispersion box 4 is provided with a conveying notch on one side of the conveyor belt 2, the inner wall of the conveying notch is fixedly connected to the upper end of the slide plate 8, the lower end of the slide plate 8 contacts the upper surface of the conveyor belt 2, the side walls of the dispersion box 4 are respectively fixedly connected to the two side baffles 9, the upper end surfaces on both sides of the dumping hole plate 6 are fixedly connected to the inward inclined plate 7, the slide plate 8 is provided with a plurality of fine holes for drainage, the guide buffer assembly is composed of a fixed sleeve 11 and a plurality of guide buffer scrapers 12, the side wall of the side baffle 9 located on one side of the slide plate 8 is fixedly connected to the control motor 10 through a mounting seat, the output end of the control motor 10 is fixedly connected to the fixed sleeve 11 through a driving shaft, and the outer side wall of the fixed sleeve 11 is fixedly connected to the side walls of the plurality of guide buffer scrapers 12;

[0032] It should be noted that: when a certain type of spherical vegetables to be transported and sorted are poured into the dispersion box 4, most of the dirt on the surface of the poured spherical vegetables will be washed away by clean water, and then the hydraulic push rod 5 in the dispersion box 4 is synchronously controlled to start, so that the pouring hole plate 6 slowly moves up to push out the spherical vegetables to be transported. The starting and conveying method in which the pouring hole plate 6 is pushed out of the water can be better suitable for spherical vegetables that sink into the water (such as potatoes and onions) and float on the water (such as tomatoes);

[0033] During the first conveying stage of the spherical vegetables, the spherical vegetables are pushed out by the pouring hole plate 6 and enter the sliding plate 8 through the conveying gap of the dispersion box 4. When the spherical vegetables slide and roll on the sliding plate 8, part of the water they carry will flow down through the fine holes. The spherical vegetables that slide and roll obliquely and enter the conveyor belt 2 will maintain a kinetic energy converted from gravitational potential energy. In this process, the control motor 10 is kept in the starting state, and the plurality of guide buffer scrapers 12 are driven to rotate slowly through the fixing sleeve 11, so that the rotation speed of the guide buffer scraper 12 is synchronized with the conveying speed of the conveyor belt 2. When the spherical vegetables with kinetic energy move to the guide buffer scraper 12, they will be gradually offset by the rotating guide buffer scraper 12, so that the spherical vegetables can maintain a static and stable conveying state on the conveyor belt 2.

[0034] The above advantages are as follows: the spherical vegetables can be dispersed by the dispersion box 4 and pushed out in an orderly manner to the conveyor belt 2 for transportation, and the guide buffer component scrapes and blocks the spherical vegetables with kinetic energy, so that the spherical vegetables can maintain a subsequent stable transportation state under the action of guidance and buffering;

[0035] A two-way guide plate 13 is arranged above the conveyor belt 2, and a guide ring cover 14 is connected to both sides of the two-way guide plate 13. A directional assembly for determining the position of the spherical vegetables being transported is connected to the bottom of the guide ring cover 14, and a take-off and unloading mechanical arm 17 is arranged on one side of the directional assembly. A pneumatic gripper 18 is movably connected to the output end of the take-off and unloading mechanical arm 17, and a cleaning assembly is arranged below the pneumatic gripper 18;

[0036] Further, the upper end surface of the support frame 3 is fixedly connected to the bottom end of the two-way guide plate 13 through two pillars, the side wall of the two-way guide plate 13 is fixedly connected to the side wall of the receiving ring cover 14, the edge side wall of the two-way guide plate 13 and the inner side wall of the receiving ring cover 14 are located in the same vertical plane, the orientation component is composed of an electrically controlled rotating seat 15 and an orientation seat 16, the bottom end of the receiving ring cover 14 is fixedly connected to the top of the electrically controlled rotating seat 15, the inner side wall of the electrically controlled rotating seat 15 is rotatably connected to the orientation seat 16, and a plurality of orientation grooves are provided on the orientation seat 16, the cleaning component is composed of a cleaning table 21 and a plurality of limiting arc plates 23, the top of the conveying platform 1 is fixedly connected to a cleaning motor 19, the output end of the cleaning motor 19 is fixedly connected to a weighing seat 20 through a rotating shaft, the top of the weighing seat 20 is fixedly connected to the bottom end of the cleaning table 21, and the outer side wall of the cleaning table 21 is fixedly connected to the outer arc side wall of the limiting arc plate 23 through a plurality of electrically controlled push rods 22;

[0037] It should be noted that: during the second conveying stage of the spherical vegetables, the spherical vegetables will move to the two-way guide plate 13 along with the conveyor belt 2. During the movement, multiple spherical vegetables will be separated by the protruding part in the middle of the two-way guide plate 13 (the contact surface between the two-way guide plate 13 and the spherical vegetables will be smooth). Driven by the friction of the conveyor belt 2, the spherical vegetables will slide to the two sides of the two-way guide plate 13, so that the spherical vegetables move into the receiving ring cover 14, and the electric control rotating seat 15 drives the directional seat 16 to perform intermittent rotation at a fixed angle, so that the spherical vegetables entering the receiving ring cover 14 will continuously fall into the directional groove of the directional seat 16, and then the unloading robot arm 17 will control the pneumatic gripper 1 8. The spherical vegetables at the fixed position on the directional seat 16 are grasped, and the grasped spherical vegetables are placed on the top of the cleaning table 21. When the pneumatic gripper 18 grasps the spherical vegetables, the size is identified through the visual system to control the grasping force. The pneumatic gripper 18 synchronizes the identified size information to the electric control push rod 22, and synchronously controls the limiting force of the limiting arc plate 23. This is a prior art and will not be described in detail here. After the spherical vegetables are limited, the cleaning motor 19 will be controlled to start and drive the cleaning table 21 to rotate rapidly to ensure that the water and dirt on the spherical vegetables are centrifugally thrown out, and the weight of the spherical vegetables at this time is weighed by the weighing seat 20, and recorded in the entire conveying system;

[0038] The above advantages are as follows: the two-way guide plate 13 can be used for guiding and conveying, ensuring the guiding and separation of the spherical vegetables, avoiding the vegetables from being squeezed, collided or damaged during the conveying process, and the rotating cleaning table 21 centrifugally cleans the water and dirt on the spherical vegetables, ensuring the cleanliness of the vegetables in the subsequent logistics conveying system, and avoiding the excessive moisture on the vegetables, which may cause the subsequent weighing to be short of weight;

[0039] An annular auxiliary conveying disc 26 is provided on one side of the unloading robot arm 17, and a conveying and pushing assembly is provided in the annular auxiliary conveying disc 26. A guide notch is provided on one side of the conveyor belt 2, and a guide conveying ring 32 is connected between the two guide notches through a guide V-plate 31. The inner side wall of the bottom end of the guide conveying ring 32 is rotatably connected to a plurality of fan-shaped buffer baffles 33 through a torsion spring component.

[0040] Further, a circular conveying motor 24 is fixedly connected to the top of the conveying platform 1, and the output end of the circular conveying motor 24 is fixedly connected to the partition seat 27 through the control shaft 25. The side wall of the circular auxiliary conveying disc 26 is fixedly connected to the support frame 3 through the fixing frame, and the inner side wall of the circular auxiliary conveying disc 26 is rotatably connected to the partition seat 27. The conveying and pushing assembly is composed of a plurality of pushing push rods 28 and a plurality of fan-shaped push plates 29. The top of the partition seat 27 is fixedly connected to the bottom end of the fan-shaped push plate 29 through the pushing push rod 28. The outer side wall of the top of the control shaft 25 is fixedly connected to a plurality of distance sensors 30. The distance sensors 30 can synchronize with the system to determine whether the vegetables in the fan-shaped push plate 29 are pushed out;

[0041] It should be noted that: during the third conveying stage of spherical vegetables, the unloading robot arm 17 will control the pneumatic gripper 18 to grab the spherical vegetables and unload them on the fan-shaped push plate 29. The multiple fan-shaped push plates 29 in the annular auxiliary conveying tray 26 are all provided with system numbers. When the pneumatic gripper 18 places the spherical vegetables on a certain numbered fan-shaped push plate 29, the weight of the vegetables will also be recorded by the system at the same time. According to the customer orders received in the logistics conveying system, the specific weight of the vegetables required is determined, and by matching the weights of the vegetables on the different fan-shaped push plates 29 in the two annular auxiliary conveying trays 26 on both sides, the vegetables on the fan-shaped push plates 29 with specific numbers are quickly selected for combination, and the annular The fan-shaped conveying motor 24 will accurately control the rotation angle, rotate the fan-shaped push plate 29 with the selected number to the guide notch of the annular auxiliary conveying disk 26, and then start the push rod 28 to slowly push the vegetables in the fan-shaped push plate 29 into the guide V-plate 31 (the fan-shaped push plate 29 has a certain inclination angle), so that the spherical vegetables pass through the guide V-plate 31 and fall into the guide conveying ring 32, and press the fan-shaped buffer baffle 33 to make it flip, so that the spherical vegetables fall on the conveyor belt 2 with buffer, and the fan-shaped push plates 29 with the selected number will be pushed out in sequence to avoid collision or squeezing of the spherical vegetables during the guide conveying process, and the staff on the side can confirm and package according to the order;

[0042] The above advantages are as follows: in this way, multiple numbered fan-shaped push plates 29 can be used to separate and transport spherical vegetables of multiple weights, and the weights can be combined according to the weight standard of the customer's order, and the spherical vegetables in the fan-shaped push plates 29 with specific numbers can be selected to avoid the situation of short weight, and it can also ensure that the merchant can choose the appropriate weight match within a certain range, thereby ensuring the interests of customers and reducing the losses of merchants, and avoiding the chaos in the weighing area;

[0043] In this solution, the components that come into direct contact with the spherical vegetables designed for the purpose (except for structures with special instructions) are all made of rubber, and all structures used for transportation or guidance have small inclination angles, which will not cause the spherical vegetables to have large kinetic energy during transportation or guidance.

[0044] When the present invention is used, a certain type of spherical vegetables to be transported and sorted are poured into the dispersion box 4, and most of the dirt on the surface of the poured spherical vegetables will be washed away by clean water. Then, the hydraulic push rod 5 in the dispersion box 4 is synchronously controlled to start, so that the pouring hole plate 6 slowly moves upward to push out the spherical vegetables to be transported. The starting and conveying method in which the pouring hole plate 6 is pushed out of the water can be better suitable for spherical vegetables that sink into the water (such as potatoes and onions) and float on the water surface (such as tomatoes);

[0045] During the first conveying stage of the spherical vegetables, the spherical vegetables are pushed out by the pouring hole plate 6 and enter the sliding plate 8 through the conveying gap of the dispersion box 4. When the spherical vegetables slide and roll on the sliding plate 8, part of the water they carry will flow down through the fine holes. The spherical vegetables that slide and roll obliquely enter the conveyor belt 2 and maintain a kinetic energy converted from gravitational potential energy. In this process, the control motor 10 is kept in the starting state, and the fixed sleeve 11 drives a plurality of guide buffer scrapers 12 to rotate slowly, so that the rotation speed of the guide buffer scraper 12 is synchronized with the conveying speed of the conveyor belt 2. When the spherical vegetables with kinetic energy move to the guide buffer scraper 12, they will be gradually offset by the rotating guide buffer scraper 12, so that the spherical vegetables can maintain a static and stable conveying state on the conveyor belt 2. In this way, the dispersion box 4 can be used to disperse the spherical vegetables and orderly push them out to the conveyor belt 2 for transportation. The guide buffer component scrapes and blocks the pushed out spherical vegetables with kinetic energy, so that the spherical vegetables can maintain a subsequent stable conveying state under the action of guidance and buffering.

[0046] During the second conveying stage of the spherical vegetables, the spherical vegetables will move to the two-way guide plate 13 along with the conveyor belt 2. During the movement, multiple spherical vegetables will be separated by the protruding part in the middle of the two-way guide plate 13 (the contact surface between the two-way guide plate 13 and the spherical vegetables will be smooth). Driven by the friction of the conveyor belt 2, the spherical vegetables will slide to the two sides of the two-way guide plate 13, so that the spherical vegetables move into the receiving ring cover 14. The electrically controlled rotating seat 15 drives the directional seat 16 to rotate intermittently at a fixed angle, so that the spherical vegetables entering the receiving ring cover 14 will continuously fall into the directional grooves of the directional seat 16. Then the unloading robot arm 17 will control the pneumatic gripper 18 to grab the spherical vegetables at a fixed position on the directional seat 16, and place the grabbed spherical vegetables on the top of the cleaning table 21. The pneumatic gripper 18 will use the visual system to grasp the spherical vegetables when grabbing them. The system recognizes the size and controls the grasping force. The pneumatic gripper 18 will synchronize the recognized size information to the electric control push rod 22, and synchronously control the limiting force of the limiting arc plate 23. This is a prior art and will not be described in detail here. After the spherical vegetables are limited, the cleaning motor 19 will be controlled to start and drive the cleaning table 21 to rotate rapidly to ensure that the water and dirt on the spherical vegetables are centrifugally thrown out, and the weighing seat 20 is used to weigh the weight of the spherical vegetables at this time and record it in the entire conveying system. In this way, the two-way guide plate 13 can be used for guided conveying to ensure the guided separation of each spherical vegetable, and avoid squeezing, collision and damage to the vegetables during transportation. The rotating cleaning table 21 centrifugally cleans the water and dirt on the spherical vegetables, ensures the cleanliness of the vegetables in the subsequent logistics conveying system, and avoids excessive moisture on the vegetables, resulting in the subsequent weighing of short weight.

[0047] During the third conveying stage of the spherical vegetables, the unloading robot arm 17 will control the pneumatic gripper 18 to grab and unload the spherical vegetables onto the fan-shaped push plate 29. The multiple fan-shaped push plates 29 in the annular auxiliary conveying tray 26 are all provided with system numbers. When the pneumatic gripper 18 places the spherical vegetables on a fan-shaped push plate 29 with a certain number, the weight of the vegetables will also be recorded by the system at the same time. According to the customer orders received in the logistics conveying system, the specific weight of the vegetables required is determined, and the weights of the vegetables on the different fan-shaped push plates 29 in the two annular auxiliary conveying trays 26 on both sides are matched. The vegetables on the fan-shaped push plates 29 with specific numbers are quickly selected for combination. The annular conveying motor 24 will accurately control the rotation angle, rotate the fan-shaped push plates 29 with the selected number to the guide notch of the annular auxiliary conveying tray 26, and then start the pushing push rod 28 to slowly push the vegetables in the fan-shaped push plates 29 out of the slide The spherical vegetables are pushed into the guide V-plate 31 (the fan-shaped push plate 29 has a certain inclination angle), so that the spherical vegetables fall into the guide conveying ring 32 through the guide V-plate 31, and the fan-shaped buffer baffle 33 is pressed to make it flip, so that the spherical vegetables fall on the conveyor belt 2 with a buffer. The fan-shaped push plates 29 with selected numbers will be pushed out in sequence to avoid the spherical vegetables from colliding or squeezing during the guiding and conveying process. The staff on the side can confirm and package them according to the order. In this way, a plurality of fan-shaped push plates 29 with set numbers can be used to separate and convey spherical vegetables of multiple weights, and the weights can be combined according to the weight standard of the customer's order. The spherical vegetables in the fan-shaped push plates 29 with specific numbers are selected to avoid the situation of short weight, which also ensures that the merchants choose the appropriate weight match within a certain range, guarantees the interests of customers and reduces the losses of merchants, and avoids chaos in the weighing area.

[0048] 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.
