[0022] The following describes the details and working principle of the embodiments and examples of the present invention in conjunction with the accompanying drawings. The material sorting machine includes a sorting mechanism 1, 2, 3, 4, a lifting mechanism 7, 11 and a stacking mechanism, see the attached drawings. Figure 1 , X-axis is horizontal, also the left-right direction, Y-axis is longitudinal, also the front-back direction, and Z-axis is vertical, also the up-down direction. The lifting mechanism is provided with a feeding station 20 and a discharging station 19. The lifting mechanism includes a lifting support plate 16 passing through the feeding station and the discharging station. The lifting support plate delivers the paper tube 26 from the feeding station to the discharging station; the stacking mechanism includes a front push plate 9 that moves forward and backward and longitudinally arranged feeding channels 6 and 8. The feeding channel holds the paper tube 26, and the paper tube is arranged on the feeding channel. The feeding channel can use a longitudinally arranged support plate or the feeding channel can use two parallel guide rods 27. The spacing between the two guide rods is smaller than the outer diameter of the paper tube 26, and the paper tube is held by the guide rod 27; the arranging mechanism makes the paper tubes uniformly in a horizontal state, see attached Figure 7 The paper tube 26 in the figure is horizontal, the arranging mechanism is provided with at least two groups, the lifting mechanism is provided with a feed port corresponding to the discharge port of the arranging mechanism, the discharge port of the arranging mechanism is connected with the feed port of the lifting mechanism, the discharge port of the lifting mechanism is connected with the feeding channel, the discharge station of the lifting mechanism is provided with a pusher 10, the pusher can be driven by a screw mechanism or a cylinder to move left and right, or directly adopt a cylinder, that is, the piston rod of the cylinder is extended to push the paper tube into the feeding channel, see the attached Figure 4In this embodiment, the pushing member includes a cylinder 17 and a pushing plate 18. The cylinder drives the pushing plate 18 to move left and right, that is, to push the paper tube on the lifting support plate 16 into the feeding channels 6 and 8. When the pushing plate 18 is not in use, the cylinder drives the pushing plate away from the discharging station 19; the discharging port and the feeding port of the lifting mechanism are located at the feeding station 20 and the discharging station 19. In this embodiment, the discharging port of the sorting mechanism is arranged at the lower end of the frame, so the feeding port of the lifting mechanism connected thereto is also arranged at the lower end of the frame, the discharging station 19 and the feeding channel are arranged above the feeding station, and the lifting support plate feeds upward; conversely, if the discharging port of the sorting mechanism is arranged at the upper end of the frame, then the feeding station 20 of the lifting mechanism is also arranged at the upper end of the frame, and the discharging station 19 and the feeding channel are arranged below the feeding station 20. After being sorted by the sorting mechanism, the paper tube 26 is in a horizontal state, discharged from the discharge port of the sorting mechanism, and enters the lifting pallet 16 from the feed port of the lifting mechanism. The lifting pallet delivers the paper tube of the feed station to the discharge station, and the pushing member 10 pushes the paper tube of the discharge station into the feeding channel. The front push plate 9 of the stacking mechanism pushes the paper tube to move on the feeding channel so that the paper tube is arranged longitudinally in the feeding channel. After stacking to a certain number, the paper tubes are collected uniformly. The collection of the paper tubes can be done manually or by a robot. The robot is a receiving tube 25. The receiving tube is opposite to the tube core of the paper tube 26 on the feeding channel. The front push plate 9 pushes the paper tube backward so that the paper tube 26 is set on the receiving tube 25.

[0023] One group of sorting mechanisms is used for sorting paper tubes of one color number. The sorting mechanisms of the present invention are provided with at least two groups, which can be used for sorting paper tubes of at least two colors. When a paper tube with a good color needs to be sorted, the corresponding sorting mechanism is started to sort the paper tube of that color number, and the paper tube is sent to the feeding channel through the lifting mechanism and arranged neatly; when the machine sorts paper tubes of another color number, it only needs to start another group of sorting mechanisms, and there is no need to clean paper tubes of other colors, which saves the cleaning work and improves work efficiency; and the feeding channels provided are provided with two or more groups, so that paper tubes of multiple colors can be sorted at the same time. Of course, the cost of the equipment is higher. If only one group of feeding channels is provided, and the feeding channel is provided on the side of the lifting mechanism, then it can only be used for stacking paper tubes of one color number at a time. If two groups of feeding channels are provided, and the two feeding channels are respectively provided on the left and right sides of the lifting mechanism, then it can be used for stacking paper tubes of two colors at the same time, and the paper tubes on the lifting tray can enter the feeding channel on the left or right side respectively. , which is equivalent to the lifting mechanism having two discharge ports, namely the left discharge port and the right discharge port, then the corresponding pushing members are also provided with two groups, which are respectively used to push the paper tube from the left discharge port and the right discharge port, and then enter the left feeding channel and the right feeding channel respectively; in order to make the equipment structure more compact and lower the cost, one group of lifting mechanisms corresponds to two groups of sorting mechanisms, and the two groups of sorting mechanisms are symmetrically arranged on the left and right sides of the lifting mechanism. The lifting mechanism is provided with two feed ports, namely the left feed port and the right feed port, the left feed port is connected with the sorting mechanism on the left, and the right feed port is connected with the sorting mechanism on the right. In this way, two groups of sorting mechanisms are equipped with one group of lifting mechanisms, which has a more compact structure and lower cost; in order to further improve the efficiency, the lifting mechanism is provided with N groups, and they are arranged front and back, that is, the lifting mechanisms are all arranged on the side of the feeding channel, the sorting mechanism is provided with 2N groups, and two groups of sorting mechanisms are equipped with one group of lifting mechanisms. The more the number of sorting mechanisms is, the more it can be used to sort paper tubes of more colors. Of course, the number of sorting mechanisms is selected according to demand.

[0024] The sorting mechanism includes a silo 5, a material sorting component and an obliquely arranged discharge channel 13. The material sorting component sorts the paper tubes in the silo so that the paper tubes are in a horizontal state when they fall into the paper tube channel of the material sorting component. The specific structure of the material sorting component can adopt the existing technology, that is, the material sorting component includes a liftable material sorting plate, and the material sorting plates are provided with two pieces. The material sorting plates are arranged in the silo, and a paper tube channel is formed between the two material sorting plates. The width of the paper tube channel matches the thickness of the paper tube, so that the material sorting plate is lifted and lowered in the silo to push the paper tube in the silo, and the paper tube enters the paper tube channel when it is in a horizontal state, thereby ensuring that the paper tubes in the paper tube channel are all in a horizontal state; the upper end of the discharge channel 13 is the feed end, and the lower end of the discharge channel is the discharge end. The paper tube channel is connected with the feed end of the discharge channel, and the discharge end of the discharge channel 13 That is, the discharge port of the sorting mechanism, the paper tubes in the paper tube channel directly enter the discharge channel; in order to avoid paper tube blockage and ensure that the paper tubes enter the lifting support plate one by one, the discharge end is provided with a limit switch 21, and the discharge channel is provided with an isolating switch 23. An isolating chamber 22 is between the isolating switch and the limit switch, and the paper tubes in the isolating chamber are isolated from other paper tubes. When the limit switch 21 is turned on, only the paper tubes in the isolating chamber 22 enter the lifting support plate 16, ensuring that only one paper tube enters the lifting support plate at a time; the limit switch 21 and the isolating switch 23 can adopt a movable baffle, which can block the paper tube. When the baffle is removed, the paper tube enters the isolating chamber or the lifting support plate without being blocked. The limit switch and the isolating switch can also directly adopt a cylinder, and the piston rod of the cylinder can block the paper tube when it is extended, and the paper tube moves freely when the piston rod is retracted.

[0025] The paper tubes of the present invention are in a horizontal state from coming out of the sorting mechanism to being neatly arranged on the feeding channel. When the lifting support plate of the lifting mechanism is feeding the paper tube, in order to ensure that the paper tube remains stable during the rising process, the upper surface of the lifting support plate has an arc-shaped bracket 15, and the surface of the paper tube in the horizontal state coincides with the bracket, so that the paper tube is more stable on the lifting support plate 16; the lifting of the lifting support plate can be driven by a screw mechanism, a cylinder, a transmission belt, etc., see the attached Figure 4 In this embodiment, a plurality of lifting pallets are provided, and the lifting pallets are evenly mounted on a transmission chain 14, and the transmission chain is provided on a transmission wheel, and the transmission wheel is provided up and down, so that the transmission chain wound around the transmission wheel is vertically driven, and the transmission wheel is connected to a motor driving it to rotate, and the motor drives the transmission wheel to rotate, drives the transmission chain to transmit, and the lifting pallets on the transmission chain are moved by the transmission chain.

[0026] In order to ensure the stable forward and backward movement of the front push plate 9, the stacking mechanism also includes a linear guide rail 29, on which the front push plate is slidably arranged, and the linear guide rail is longitudinally installed on the frame. The front push plate 9 moves forward and backward along the linear guide rail 29, and the front push plate and the driving component that drives it to move forward and backward, the driving component can adopt a screw mechanism or a cylinder or a transmission belt, which are all conventional driving components and will not be described in detail. If the lifting mechanism is provided with two or more groups, in order to facilitate operation, the stacking mechanism also includes a rear push plate 12 for pushing the paper tubes on the feeding channel to move, and the rear push plate is also connected to the lifting component 24 that drives it to move up and down, that is, the front push plate 9 is arranged at the front end of the feeding channel, the front push plate pushes the paper tubes sent out by the front lifting mechanism backward, and the paper tubes are stacked backward, and the rear push plate 12 is arranged at the rear end of the feeding channel, the rear push plate pushes the paper tubes sent out by the rear lifting mechanism forward, and the paper tubes are stacked forward. When collecting them uniformly, the rear push plate moves up, and the paper tubes are discharged from the rear end of the feeding channel. The lifting and lowering of the rear push plate 12 can also be driven by a screw mechanism or a cylinder; if only a front push plate is provided and a rear push plate is not equipped, then the front push plate needs to be moved to the position of the lifting mechanism for operation to operate, and paper tube stacking can also be achieved, but the difficulty of controlling the front push plate will increase.

[0027] In order to realize automation, accurately control the number of paper tube stacks, and improve the efficiency of material sorting, a counter 28 is provided on the feeding channel, and the sorting mechanism, lifting mechanism, stacking mechanism, and counter are all connected to the electrical controller. The counter is provided at the junction of the feeding channel and the lifting mechanism, so that the counter can accurately detect the number of paper tubes entering the feeding channel from the lifting mechanism. The counter sends the detected information to the electrical controller, and the electrical controller sends instructions to the sorting mechanism, lifting mechanism, and stacking structure, so that each mechanism performs corresponding actions. If the paper tube needs to be coded, a coding station is provided on the lifting path of the lifting mechanism, and the lifting plate can be coded when it sends the paper tube from the feeding station to the discharging station. There is enough space to install the inkjet printer, and it will not affect the transportation of the paper tube.

[0028] The following describes the operation of the material sorting machine in conjunction with the accompanying drawings. In this embodiment, the lifting mechanism is provided with two groups, namely the front lifting mechanism 7 and the rear lifting mechanism 11, and the sorting mechanism is provided with four groups, namely the No. 1 warehouse 1, the No. 2 warehouse 2, the three warehouses 3 and the No. 4 warehouse 4. The stacking mechanism is provided with two groups, including a left feeding channel 6 and a right feeding channel 8. The left and right feeding channels are respectively arranged on both sides of the lifting mechanism, the No. 1 warehouse 1 and the No. 2 warehouse 2 are arranged on both sides of the front lifting mechanism 7, and the No. 3 warehouse 3 and the No. 4 warehouse 4 are arranged on both sides of the rear lifting mechanism 11, that is, the No. 1 warehouse and the No. 2 warehouse share The front lifting mechanism, the No. 3 warehouse and the No. 4 warehouse share the rear lifting mechanism, and the pushing piece 10 is provided with four groups, namely the No. 1 pushing piece, the No. 2 pushing piece, the No. 3 pushing piece and the No. 4 lifting piece; the four warehouses can store paper tubes of four different colors. When one of the paper tubes of one color needs to be sorted, the warehouse is started. For example, when the paper tubes in the No. 1 warehouse 1 need to be sorted, the No. 1 warehouse 1 is started, and the other warehouses are stopped. The No. 1 pushing piece is in motion, and the pushing plate of the No. 2 pushing piece is away from the discharging station to avoid blocking the paper tube from entering the feeding channel. The front push plate 9 is in operation, and the rear push plate 12 moves up to make way.The paper tubes in the silo of bin No. 1 are sorted by the feeding parts, and the paper tubes enter the discharge channel 13 in a horizontal state. Due to the inclined setting of the discharge channel, the paper tubes automatically move to the discharge end of the discharge channel, the isolating switch 23 is turned on, and a paper tube enters the isolation chamber 22. The isolating switch is closed to isolate the paper tube from the paper tube behind. Then, the limit switch 21 is turned on, and the paper tube in the isolation chamber enters the lifting support plate 16 of the lifting mechanism. The lifting support plate transports the paper tube to the discharge station 19 and sprays the code on the paper tube during the transportation process. On the other side, the limit switch 21 is closed, and the isolating switch 23 is turned on again, and the next paper tube enters In the isolation cavity 22, wait for the next lifting support plate 16 to move to the feeding station 20; when the lifting support plate sends the paper tube to the discharging station 19, the pushing plate 18 of the No. 1 pushing piece pushes the paper tube on the lifting support plate into the feeding channel, and the left feeding channel 6 or the right feeding channel 8 is selected according to the demand, and then the pushing plate 18 is reset. When the paper tube enters the feeding channel, the counter sends the detection information to the electrical controller, and the front push plate 9 moves backward to push the paper tube to move backward one station. The stroke of one station is equivalent to the length of one paper tube, so that the paper tube is arranged longitudinally on the feeding channel in a horizontal state. Then the front push plate 9 moves forward and resets, and the operation is repeated until the number of paper tubes on the feeding channel reaches a preset value, and the electrical controller sends instructions to each mechanism, at which time the front push plate 9 moves backward to push all the paper tubes on the feeding channel into the material receiving pipe 25, which collects them uniformly, and then the front push plate 9 resets; if paper tubes of another color number need to be sorted, only the No. 1 bin needs to be stopped and other bins can be started, and there is no need to clean the bin 5, saving manpower and cleaning time; and the present invention is equipped with two feeding channels, which can sort two groups of color numbers at the same time, such as the No. 1 bin 1 and the No. 3 bin 3, one Bin No. 1 and bin No. 4 can operate at the same time, and the two bins respectively use the left feeding channel 6 and the right feeding channel 8, and the working principle is the same as above; the present invention can also use two bins for paper tubes of the same color number, and sort them at the same time, doubling the speed; if bin No. 3 and bin No. 4 are sorting, the rear push plate 12 moves down, and each time the paper tube enters the feeding channel, the rear push plate 12 pushes the paper tube forward one station until the number of paper tubes on the feeding channel reaches a preset value, at this time the rear push plate 12 moves up to make way, and the front push plate 9 pushes out and collects the paper tubes on the feeding channel, that is to say, the paper tubes on the feeding channel are uniformly discharged from the rear end.
