Example 1

The following description of the sorting system according to the present invention is made with reference to the accompanying drawings, as shown in fig. 1, and the sorting system includes a plurality of balance sorter 100 and a plurality of conveyors 200 connected in a line, wherein the balance sorter 100 and the conveyors 200 are arranged alternately, that is, in the order of conveyor 200-balance sorter 100- … … -conveyor 200, and the specific number thereof is designed according to different application requirements, for example, 2 balance sorters and 3 conveyors, which are not limited herein.

The balance sorter 100 may be of any of the various possible configurations known in the art, such as those disclosed in prior art application nos. 202110141559.6, 201810597624.4, 202021492825.7, 202020105640.

As shown in fig. 2, the balance 121 of the balance sorter 100 according to the present embodiment is driven to rotate by the friction roller 130. Specifically, the balance sorter 100 includes a frame 110, a plurality of rows of balance sorting units 120 are provided to the frame 110 so as to be deflectable, and the wheel surfaces of balances 121 of two adjacent rows of balance sorting units 120 are frictionally connected to a friction roller 130 located therebetween. When the friction roller 130 rotates, the balance wheels of the two rows of balance wheel sorting units 120 can be driven to rotate.

As shown in fig. 2, driven wheels 140 are disposed at both ends of each of the friction rollers 130, and the driven wheels 140 at both ends of each of the even-numbered friction rollers 130 are connected to the driven wheels 140 at corresponding ends of the two odd-numbered friction rollers 130 at both sides thereof by a transmission belt (not shown). For example, the input end of the balance wheel sorting machine is used for numbering a plurality of friction rollers towards the output end, namely the friction roller closest to the input end is numbered as 1, the rear friction roller is numbered as 2, the rear friction roller is numbered as 3, and the like, and the last friction roller is numbered as n.

As shown in fig. 2, the number of the friction rollers is 6, in this case, the driven wheel at the first end of the friction roller 130 with number 1 is connected to the third transmission shaft of the balance sorter, the driven wheel 140 at the second end of the friction roller 130 with number 1 is connected to the driven wheel 140 at the second end of the friction roller 130 with number 2 through a transmission belt (not shown in the figure), the driven wheel 140 at the first end of the friction roller 130 with number 2 is connected to the driven wheel 140 at the first end of the friction roller 130 with number 3 through another transmission belt, the driven wheel at the second end of the friction roller 130 with number 3 is connected to the driven wheel at the second end of the friction roller with number 4 through another transmission belt, and so on, the driven wheels at the second end of the friction roller with number 6 are connected to the driven wheel at the second end of the friction roller with number 5 through a transmission belt, so that a plurality of transmission belts are distributed on two sides of the balance sorter in an interlaced manner. Such a structure allows the plurality of rubbing rollers 130 to be driven by one motor while rotating.

As shown in fig. 2, in order to facilitate tension adjustment of the transmission belts, each transmission belt is further connected with an adjusting wheel 150, the adjusting wheel 150 is located below the driven wheel and is rotatably located on the inner side of the transmission belt, and is arranged on the frame 110 of the balance sorting machine 100 in a position adjustable manner along a direction perpendicular to the conveying surface of the balance sorting machine 100, and the tension of each transmission belt is adjusted by adjusting the installation height of the adjusting wheel 150 to ensure the stability of transmission.

The conveyor 200 can likewise be any of various known conveying devices, such as a belt conveyor or a roller conveyor or a drag conveyor. As shown in fig. 3, in the present embodiment, the conveyor 200 is described by taking a belt conveyor as an example, the conveyor 200 includes a frame 230, two ends of the frame 230 are respectively provided with a rotating roller 240, and a belt 260 is sleeved on the two rotating rollers 240.

Usually, each balance sorter 100 has an independent motor to drive the balance to rotate, and each conveyor 200 has an independent motor to drive a roller, a belt, a chain or the like to rotate to realize conveying, so that a plurality of motors are needed, and such a structure requires more energy consumption, is obviously not economical, increases workload of wiring, motor installation and the like, and is not beneficial to equipment maintenance.

As shown in fig. 1, at least one balance sorter 100 in the line is connected to at least one conveyor 200 through a transmission mechanism 300 to drive them to be conveyed in the same direction by a motor (not shown), so that the number of motors can be effectively reduced.

The conveyor 200 and the balance sorter 100 may be two adjacent apparatuses in a line, or two apparatuses spaced apart from each other in the line. The plurality of conveyors 200 and the balance sorter 100 may be connected by one transmission mechanism 300, or may be connected by a plurality of transmission mechanisms 300.

As shown in fig. 4, in the present embodiment, each balance sorter 100 is connected to the conveyor 200 connected to both ends thereof through a transmission mechanism 300, and when the motor drives any balance sorter 100 or conveyor 200 to convey, the motors can drive other balance sorters 100 and conveyors 200 to convey simultaneously through a plurality of transmission mechanisms 300, so that the number of motors can be reduced to the maximum extent. It is of course also possible to connect only part of said balance sorter 100 to the conveyor 200, which is engaged at both ends, by means of the transmission 300 to realize one motor-driven three devices.

As shown in fig. 4, the transmission mechanism 300 may be a structure formed by a sprocket and a chain, a structure formed by a pulley and a synchronous belt, or a gear transmission structure. Specifically, the transmission mechanism 300 includes a first transmission wheel 310, a second transmission wheel 320, a third transmission wheel 330, a tension wheel 340 and a conveying belt 350, the first transmission wheel 310, the second transmission wheel 320, the third transmission wheel 330 and the tension wheel 340 may be pulleys or sprockets, and the conveying belt 350 is a belt or a chain. The first driving wheel 310, the second driving wheel 320, and the tension wheel 340 are connected to the inner side of the conveyor belt, and the third driving wheel is connected to the outer side of the conveyor belt 350, so that the rotation direction of the third driving wheel 330 is opposite to the rotation direction of the first driving wheel 310, the second driving wheel 320, and the tension wheel 340.

As shown in fig. 4, the first driving wheel 310 is coaxially connected to an end of the first driving shaft 210, and the first driving shaft 210 is rotatably provided on the conveyor 200 engaged with the input end of the balance conveyor 200. The second transmission wheel 320 is coaxially connected to the end of a second transmission shaft 220, the second transmission shaft 220 being rotatably arranged on the conveyor 200 engaged with the output end of the balance sorter 100. The third driving wheel 330 is coaxially disposed on the third transmission shaft 160 of the balance sorter 100, and the third driving wheel 330 is located outside the conveyor belt 350. The tension pulley 340 is disposed between the second transmission wheel 320 and the third transmission wheel 330, and is rotatably provided on the support shaft 170 of the balance sorter 100, and the support shaft 170 is movably provided on the frame of the balance sorter in a direction parallel to the conveying direction of the conveyor.

The transmission mechanism 300 can effectively make the rotation direction of the friction roller 130 opposite to the direction of the roller 240 of the conveyor 200 so that the rotation direction of the balance wheel is the same as the rotation direction of the roller 240, and can effectively reduce the possibility of unstable conveyor conveying caused by power loss in the conveying process of a conveying belt.

Of course, in another embodiment, the tension wheel 340 is not necessary, that is, only the first driving wheel 310, the second driving wheel 320 and the third driving wheel 330 may be provided, the conveyor belt is directly sleeved on the first driving wheel 310 and the second driving wheel 320, and the third driving wheel is also connected to the outer side of the conveyor belt.

As shown in fig. 3 and 4, the first transmission shaft 210 and the second transmission shaft 220 may be a central shaft 241 of the rollers 240 at both ends of the conveyor, and the third transmission shaft 160 may be a central shaft of one friction roller 130 of the balance sorter 100. Such a structure does not facilitate installation of the belt 350 and the belt between the friction rollers.

As shown in fig. 2 and 4, the third transmission shaft 160 is located below the swing sorting unit of the balance sorter 100, is rotatably disposed on the frame 110 of the balance sorter 100 and is parallel to the friction roller 130 driving the balance, and is close to one end of the balance sorter 100, as shown in fig. 4, which is close to the left end of the balance sorter 100. Meanwhile, a driving wheel 180 is coaxially arranged on the third transmission shaft 160, the driving wheel 180 is connected with a driven wheel 140 at one end of the friction roller 130 through a driving belt 190, and the driven wheel connected with the driving wheel is preferably arranged on the leftmost friction roller 130, so that the driving belt installation between the other friction rollers 130 is facilitated.

As shown in fig. 3 and 4, the heights of the first and second transmission shafts 210 and 220 correspond to the height of the third transmission shaft 160 in order to match the height of the third transmission shaft 160. Specifically, a first transmission shaft 210 located inside one of the rollers 240 of the conveyor is rotatably provided below the roller 240, a second transmission shaft 220 located inside the other roller 240 is rotatably provided below the roller, both the first transmission shaft 210 and the second transmission shaft 220 are provided with a roller body 250, and a belt 260 of the conveyor 200 is fitted over the rollers 240 and the roller body 250. Meanwhile, the outer diameters of the first driving wheel and the second driving wheel are larger than the outer diameters of the third driving wheel and the tensioning wheel, the tops of the first driving wheel and the second driving wheel are higher than the top of the third driving wheel, and the bottoms of the first driving wheel and the second driving wheel are lower than the bottom of the third driving wheel, so that the conveying belt can be in closer contact with the first driving wheel and the second driving wheel to ensure the stability of power transmission.

At this time, as shown in fig. 3, in order to avoid the belt 260 of the conveyor 200 occupying too much space and exposing the belt, a supporting roller 270 is disposed above the first transmission shaft 210 and the second transmission shaft 220, the supporting roller 270 is located below the belt 260 and is used for lifting the lower layer of the belt 260 upward, meanwhile, the supporting roller 270 located above the first transmission shaft 210 is biased to the right side of the first transmission shaft 210, and the supporting roller 270 located on the second transmission shaft 220 is biased to the left side of the second transmission shaft 220, so that the belt 260 can be contacted with the roller bodies on the first transmission shaft 210 and the second transmission shaft 220 as much as possible to ensure the stability of the conveying. Meanwhile, a protective cover 280 for shielding the roller body 250, the carrier roller 270 and the belt 260 at two ends is arranged on the frame.

As shown in fig. 1, when the conveyors 200 are located at the input end and the output end of the whole line, that is, when the conveyors 200 are the first conveyor and the last conveyor of the line, the first conveyor 200 only needs to be provided with the first transmission shaft; the last of said conveyors only needs to be provided with a second transmission shaft.

The motor (not shown) for driving the conveyor 200 and the balance sorter 100 to synchronously convey may be mounted on the conveyor or the balance sorter. It may be a motor integrated in one of the rollers of the conveyor, in this case the motorized roller. Alternatively, the motor may be located outside the conveyor or the balance sorter. Preferably, the motor is fixed on a frame of the balance wheel sorting machine and positioned in the frame, and is connected with the third transmission shaft and drives the third transmission shaft to rotate.

Example 2

This embodiment differs from embodiment 1 described above in that: as shown in fig. 5 and 6, adjacent balance sorter 100 and conveyor 200 are connected by a transmission 300, and the two transmissions 300 connected to balance sorter 100 are located on both sides thereof.

As shown in fig. 5, each of the balance sorter 100 is connected to the conveyor 200 on its right side by a transmission 300 on its upper side, and each of the balance sorter 100 is connected to the conveyor 200 on its left side by another transmission 300 on its lower side. At this time, the first transmission shaft and the first transmission wheel and the second transmission wheel on the conveyor 200 are located at the upper and lower sides of the conveyor 200.

As shown in fig. 6, the transmission mechanism 300 is constructed in accordance with the embodiment 1, but the second transmission shaft connected to the second transmission wheel 320 is not provided on the conveyor at the output end and/or the input end of the balance conveyor but on the balance sorter 100. Meanwhile, the second transmission wheels of the two transmission mechanisms connected to the two sides of the balance wheel sorting machine are arranged on the same second transmission shaft, namely the second transmission shaft is arranged on the frame of the balance wheel sorting machine in a rotatable manner, and the two ends of the second transmission shaft extend out of the two sides of the frame of the balance wheel sorting machine. At this time, the conveyor is still configured as in embodiment 1 above.

Example 3

This embodiment differs from embodiment 1 described above in that: instead of alternating the balance sorter 100 and the conveyor 200, two or more balance sorters 100 may be positioned in close proximity with a conveyor 200 at the input of the first balance sorter 100 and a conveyor 200 at the output of the last balance sorter 100. For example, the arrangement may be made in the order "conveyor 200-balance sorter 100-conveyor 200". Alternatively, the arrangement may be performed in the order "conveyor 200-balance sorter 100-conveyor 200", in which case all or part of balance sorter 100 and conveyor 200 may be connected by a transmission structure to share a motor.

At this time, each belt conveyor may have an independent motor.

That is, in the present embodiment, only the plurality of conveyors 200 in the wire body are connected by the transmission mechanism 300 so as to share one power source. At this time, each of the balance sorter 100 may have an independent power source.

Example 6

The present embodiment differs from the above embodiments in that: as shown in fig. 4 and 6, the balance sorter 100 has only one balance, and the number of the conveyors 200 is one or two, and when one, the conveyor 200 may be provided at the input end or the output end of the balance sorter 100, and when two conveyors 200 are provided, one is provided at the input end of the balance sorter 100 and the other is provided at the output end of the balance sorter 100, and in this case, the balance sorter 100 and the conveyors 200 are connected by a transmission mechanism 300 to drive them to be conveyed in the same direction by one motor.
