The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
The first embodiment is as follows:
the embodiment is a linear crossing sorting system, and as shown in fig. 1, the linear crossing sorting system in the embodiment includes a goods feeding portion and a linear crossing sorting machine, which are sequentially arranged, and an outlet of the goods feeding portion is in butt joint with a feeding port of the linear crossing sorting machine. The goods feeding part comprises a feeding conveyor belt which can continuously convey goods to the linear cross sorting machine.
Referring to fig. 2 and 5, the linear cross sorting machine in this embodiment includes a frame 1 and a circulating track 3 disposed on the frame 1, a plurality of connected trolleys 4 are sequentially disposed on the circulating track 3, each trolley 4 is used for sorting goods, each trolley 4 can circularly move along the direction of the circulating track 3 under the action of a forward driving mechanism, and the linear cross sorting machine further includes a power taking mechanism for realizing the electrical communication of the trolley 4. Each trolley 4 is independently provided with a material distribution belt 41, the material distribution belt 41 can be driven by a material distribution driving mechanism to rotate along the direction vertical to the feeding direction of the circulating track 3, and the material distribution of goods on the material distribution belt 41 of the trolley 4 is realized, and correspondingly, a plurality of material distribution outlets 2 are arranged on the rack 1.
Two ends close to the bottom of the trolley 4 are respectively provided with a roller, at least one of the rollers is a driving roller 410, and the transmission of the material distribution belt 41 can be realized by connecting the material distribution belt 41 with the rollers in a tensioning way. The forward driving mechanism of the trolley 4 along the direction of the circulating track 3 can be a linear driving motor, so that the forward process of the trolley 4 can be ensured to be stable, and the noise is low.
Referring to fig. 3, the circulating rail 3 of the present invention includes a straight rail portion 31 disposed opposite to each other in a vertical direction and two arc rail portions 32 symmetrically disposed at two ends of the straight rail portion 31, so that when the cart 4 moves to an area where the straight rail portion 31 located above is located, left and right sorting of goods is performed, that is, a linear cross sorting effect is formed on the straight rail portion 31 located above.
Referring to fig. 4(a), 4(b) and 5, the linear cross sorting system of the present invention further includes a control unit including a controller connected to the forward driving mechanism of the linear cross sorting machine for controlling the movement and the distribution of the carts 4, two transmitting sensors respectively provided on the frame 1 adjacent to each distribution outlet 2, and two receiving sensors respectively provided on each cart 4. The emission sensors comprise a forward emission sensor 51 and a reverse emission sensor 52 for sending signals to the trolley 4, the forward emission sensor 51 sends forward signals to the trolley, and the reverse emission sensor 52 sends reverse signals to the trolley. A driving card is arranged on the trolley 4, the receiving sensor is connected with the driving card, and the driving roller 410 of the trolley is also connected with the driving card. The forward rotation transmitting sensor 51 and the reverse rotation transmitting sensor 52 are normally in a normally closed state. Here, the transmission direction of the material separating belt 41 brought about when the cart 4 rotates forward is taken as a first direction; on the contrary, the transmission direction of the material separating belt 41 brought by the reverse rotation of the trolley 4 is taken as the second direction. Therefore, when the goods on the trolley 4 moving to the corresponding material distribution outlet 2 need to be distributed in the first direction, the forward rotation transmitting sensor 51 arranged at the corresponding material distribution outlet 2 is started and transmits a signal, when the trolley 4 moves to the area corresponding to the forward rotation transmitting sensor 51, one receiving sensor of the trolley 4 receives the signal, the driving card sends a forward rotation signal to the driving roller 410 of the trolley according to the received signal of the receiving sensor, so that the goods on the trolley 4 are distributed in the first direction, and conversely, the goods on the trolley 4 are distributed in the second direction. In the invention, the control system of the host is not directly connected with the trolley 4, but the transmitting sensor is arranged and is coupled with the signal of the receiving sensor on the trolley 4, so that the transmission of the control signal to the trolley 4 is realized, and each trolley 4 is not required to be provided with a group of wires connected with the control system, thereby avoiding the winding of a wire body.
Referring to fig. 6, the forward rotation transmitting sensor 51 and the reverse rotation transmitting sensor 52 of the present invention are provided on the lower side of the upper linear rail portion 31, which are sequentially provided from top to bottom through a vertically provided transmitter mounting plate 311, and correspondingly, a vertically provided receiver mounting plate 42 is also provided on the lower side of each cart 4. The two groups of transmitting sensors and the two groups of receiving sensors are arranged in the vertical direction, so that the accurate transmission of signals in the moving process of the trolley 4 can be ensured, and the signal interference between the two groups of sensors can not be caused.
The forward rotation transmitting sensor 51 and the reverse rotation transmitting sensor 52 of the present invention are located near the front half (the direction indicated by the black arrow in fig. 1 is "front") of each of the material discharge ports 2, and therefore, it is possible to ensure smooth discharge of large goods from the material discharge ports 2 without hitting the partition of the material discharge ports 2.
In some embodiments of the invention, the control unit further comprises a set of correlation photosensors 53 for sensing the cargo, arranged near the feed end of the upper linear track section 31, and a counter 54 is arranged on the machine frame 1 near the feed end of the upper linear track section 31, which is capable of counting the number of trolleys 4 that enter the linear track section 31. In some embodiments of the invention, the feed control unit further comprises a counting sensor for counting the number of trolleys 4, the counter 54 being located in the direction downstream of the correlation photosensor 53.
The length L of the goods can be calculated by sensing the time t when the goods pass through the correlation photoelectric sensor 53 and combining the conveying speed v of the loading conveyor belt to the goods, that is, L = v × t. Then, the controller calculates the required number of the trolleys 4 according to the length of the goods, and determines the steering direction of the distribution belt 41 of the trolleys 4 according to the goods sorting requirement, thereby realizing the conveying and distribution of the goods. Referring to fig. 7, in some embodiments of the present invention, the electricity taking mechanism of the linear crossing sorting machine of the present invention includes a trolley wire 61, and a current collecting arm guide portion, wherein the current collecting arm guide portion includes at least one current collecting arm guide groove 62 formed in the trolley wire 61 in a direction close to the direction of conveyance of the trolley 4, and the width of the current collecting arm guide groove 62 in the direction close to the direction of conveyance of the trolley 4 is gradually reduced from the upper edge of the current collecting arm guide groove 62 to the bottom of the groove. The depth of the collector arm guide groove 62 gradually decreases toward the trolley wire 61. Therefore, the collector arm 49 can be surely moved smoothly in the direction of the trolley wire 61 along the collector arm guide groove 62 without affecting the movement of the collector arm 49 due to the arrangement of the collector arm guide groove 62.
As shown in fig. 8, a first guide opening 63 is further provided at the end of the collector arm guide groove 62, and the width of the first guide opening 63 is gradually reduced along the advancing direction of the cart 4, so that the collector arm 49 can be positioned at the center of the groove bottom of the collector arm guide groove 62 after entering the first guide opening 63. The present invention further includes a second guide port 64 connected to the trolley wire 61, and the width of the second guide port 64 is gradually reduced along the advancing direction of the cart 4 (the direction of sliding into the trolley wire 61). The width of the second guide opening 64 near the end of the first guide opening 63 is greater than the width of the first guide opening 63 near the second guide opening 64. Therefore, the current collecting arm 49 can be further centered and guided by the second guide opening 64, and can be smoothly slid into the trolley wire 61 to be electrically conducted.
In some embodiments of the present invention, the trolley wires 61 include five groups arranged in parallel, and the number of the collector arm guide grooves 62 is three, that is, only one of the adjacent trolley wires 61 is connected to the collector arm 49. Therefore, the installation pitch of the current collecting arms 49 is increased, and the current collecting arms are surely guided into the trolley wire 61, so that the current collecting arms 49 are in good contact with the trolley wire 61, and the power supply is stable.
The design of the guide grooves 62 of the collector arms ensures that the collector arms can be guided into the trolley wire 61 even when the collector arms are deviated in all directions and vibrate.
The arrangement length of the sliding contact line of the electricity taking mechanism of the straight-line cross sorting machine is not arranged along the circumferential direction of the whole circulating track in the prior art, but is only arranged along a partial area of the circumferential direction of the circulating track. In addition, the present invention does not provide all the trolleys 4 with current collecting arms, but only provides a part of the trolleys 4 with current collecting arms, and electrically connects the trolleys 4 in series, so that at least one trolley can keep in contact with the trolley wire 61 to get electricity while each trolley 4 moves along the circulating track 3. Therefore, the number of the current collecting arms 49 is reduced, the cost of the trolley 4 is reduced, the number of times of contact between the current collecting arms 49 and the trolley wire 61 is reduced to the maximum degree, and the current collecting arms 49 of each trolley are stably connected with the trolley wire 61 by combining the structure of the current collecting arm guide part, so that the electricity taking process is stable.
In some embodiments, the trolleys 4 provided with the collecting arms 49 are arranged at equal intervals along the circulation track 3, so as to always ensure that at least one of the trolleys is in contact with the trolley line; it is clear that the trolleys 4 provided with the current-collecting arms 49 can also be arranged at unequal intervals, as required, just to ensure that during the movement of each trolley, one remains in electrical communication with the trolley line 61.
The trolley 4 comprises a driving roller 410, a driven roller and a material distribution belt 41 which is arranged on the driving roller 410 and the driven roller in a tensioning mode. The relative distance in the radial direction between the drive roller 410 and the driven roller of the carriage 4 is adjustable. This can be achieved by providing a trolley tensioning adjustment mechanism at the roller of the drive roller 410 or the roller of the driven roller of the trolley 4.
Referring to fig. 9, in some embodiments of the present invention, the trolley tension adjusting mechanism includes a connection plate 71 having two ends engaged with the roller shafts of the driving roller 410 and the driven roller, respectively, and the connection plate 71 is disposed at the side of the trolley 4. At least one end of the connecting plate 71 is provided with an adjusting groove 73 positioned on the side surface of the roller shaft of the driving roller 410 or the driven roller, an adjusting bolt 75 penetrating through the roller shaft is arranged in the adjusting groove 73, the adjusting bolt 75 is perpendicular to the roller shaft, and correspondingly, an adjusting screw hole for installing the adjusting bolt 75 is arranged on the roller shaft in a penetrating manner. The axial center line of the adjusting screw hole is arranged in a direction perpendicular to the roller shaft, one end of the roller shaft is abutted against the groove bottom of the adjusting groove 73 (the end is taken as a first end), the other end (the end is taken as a second end) extends into the adjusting screw hole, a jacking nut 76 is further arranged on one side, close to the first end, of the adjusting screw hole of the adjusting bolt 75, and the jacking nut 76 is abutted against the roller shaft in a normal use state. When the distance between the drive roller 410 and the driven roller of the trolley 4 needs to be adjusted, the jacking nut 76 is moved towards the direction far away from the roller shaft (namely the direction close to the first end), then the adjusting bolt 75 is rotated and the stretching length of the jacking nut in the adjusting screw hole is controlled, when the distance between the roller shafts of the drive roller and the driven roller needs to be increased, the adjusting bolt 75 is moved towards the direction close to the first end from the adjusting screw hole, after the distance is adjusted to a proper position, the jacking nut 76 is rotated to abut against the side surface of the roller shaft, and the tensioning adjusting effect of the drive roller 410 and the driven roller of the trolley 4 can be realized. The tensioning adjustment of the trolley 4 can be quickly realized by utilizing the flat head bolt structure which is very easy to obtain in industry and has low cost, the efficiency is high, and the cost cannot be obviously increased.
A clamping groove 72 for clamping the roll shaft is arranged on the connecting plate 71 at one end provided with the trolley tensioning adjusting mechanism, and the surface of the end part of the roll shaft, which is in contact with the clamping groove 72, is correspondingly set to be a plane.
A clearance groove 74 for accommodating an adjusting tool is correspondingly formed on the connecting plate 71 on a side close to the second end of the adjusting bolt 75. The width of the clearance groove 74 is greater than the width of the catch groove 72.
In other possible embodiments of the present invention, the structure of the connecting plate 71 may not be provided, and only the adjusting groove 73 is provided on the body of the trolley 4 where the roll shaft of the trolley tensioning adjusting mechanism needs to be provided, and the adjusting bolt 75 and the tightening nut 76 are correspondingly provided, which will not be described herein again.
Referring again to fig. 9, in some embodiments of the present invention, a wheel mounting plate 43 is further disposed directly below the bottoms of the two ends of the trolley 4, a side wheel 44 and a front wheel 45 are disposed on the wheel mounting plate 43, the two side wheels 44 of each trolley 4 are disposed near the ends of the trolley 4, and accordingly, a guide groove 33 (see fig. 3) for accommodating the front wheel 45 is disposed on the circulating track 3 along the circumferential direction thereof, so that the front wheel 45 can be ensured to move in the guide groove 33 along the direction of the circulating track 3. Meanwhile, the side wheels 44 are in contact with the outer surface of the bottom surface of the guide groove body 33, and thus, by disposing the side wheels 44 and the front wheels 45 at both sides of the main body of the circulation rail 3, it is ensured that the cart 4 is not separated from the circulation rail 3 and the cart 4 can be smoothly moved along the circulation rail 3.
Referring to fig. 10, mounting holes 431 are respectively formed at corners of two opposite edges of a plate body of the wheel body mounting plate 43 on which the front wheel 45 is mounted, the present invention further includes a fixing shaft 46 passing through the mounting holes 431, and a snap spring, a nut or other limiting structure may be provided at a distal end of the fixing shaft 46 to prevent the fixing shaft 46 from being separated from the mounting holes 431. Thus, the connection of two adjacent trolleys 4 can be achieved by connecting a connecting piece 48 between the wheel mounting plates 43 of two adjacent trolleys 4 by the fixed shaft 46. At the same time, the connecting piece 48 can rotate relative to the fixed shaft 46, so that the trolley 4 can smoothly turn when passing through the arc-shaped track part 32 of the circulating track 3.
In some embodiments of the present invention, the side wheels 44 and the front wheels 45 are located right under the body of the cart 4, so that the width of the cart 4 along the length direction of the circulating track 3 is relatively small, the gap between two adjacent carts 4 is small, the volume of the cart 4 is smaller, and the turning radius required by the cart 4 when passing through the arc-shaped track part 32 is reduced, thereby reducing the height of the arc-shaped track part 32, correspondingly reducing the height of the linear cross sorting machine, and correspondingly reducing the energy consumption and cost of the whole system in production and use.
In some embodiments of the present invention, a rail tensioning adjustment mechanism is further disposed between the linear rail portion 31 and the arc rail portion 32, and referring to fig. 3 again, the rail tensioning adjustment mechanism of the present invention includes an adjustment rod 81 connected to the linear rail portion 31 and the arc rail portion 32, respectively, an adjustment nut 82 abutting against the linear rail portion 31 and the arc rail portion 32 is disposed on the adjustment rod 81, respectively, the distance between the linear rail portion 31 and the arc rail portion 32 can be adjusted by rotating the adjustment rod 81, and when the distance between the two is adjusted to a proper position, the relative position between the two can be fixed by the adjustment nut 82.
Referring again to fig. 3, in some embodiments of the present invention, the mutual connection of the linear rail part 31 and the arc-shaped rail part 32 has an anti-seizing mechanism by controlling the shape of the seizing of the connection of the linear rail part 31 and the arc-shaped rail part 32. The present invention is formed by providing the linear rail portion 31 and the arc-shaped rail portion 32 at the connection portions thereof with the coupling heads 91 protruding toward each other, respectively, thereby forming a seam similar to a right-angled zigzag shape at the connection portions thereof. A first slit 92 is defined as a joint extending in parallel to the moving direction of the carriage 4, and two slits adjacent to the first slit 92 are defined as second slits 93. The first slot 92 is parallel to the direction of movement of the carriage 4 and the second slot 93 is perpendicular to the first slot 92, so that during mounting it is ensured that only a partial region of the wheel body (which means a partial width in the axial direction of the wheel body) presses through the second slot 93 when the side wheels 44 of the carriage 4 pass the anti-jamming mechanism, whereby the wheel body is still partially supported on the outer side of the connection heads 91 of the linear track portions 31 and the arcuate track portions 32. Thus, the problem of the prior art that when the wheel passes through the connecting portion between the linear track portion 31 and the arc-shaped track portion 32, the contact area of the wheel body with the track (the entire width of the wheel body in the axial direction) simultaneously passes through a vertical slit perpendicular to the moving direction of the cart 4 is solved.
In other possible embodiments of the present invention, the second slit 93 may not be perpendicular to the first slit 92.
Each of the seams described in the present embodiment is in a straight line shape, and obviously, may be in an arc shape.
Example two:
the embodiment is a linear cross sorting control method, which comprises the following steps:
cargo length identification: the length of the goods is determined by detecting the time that the opposite photoelectric sensor is shielded, and the number of the required trolleys is determined.
In the step, a feeding conveyor belt is butted with a feeding opening of the straight-line cross sorting machine, the feeding speed of the goods is preset to be v, a pair of opposite photoelectric sensors are oppositely arranged on two sides of the feeding conveyor belt, the length of the goods is obtained by calculation through acquiring information of the shielded time t of the opposite photoelectric sensors, and the number n = L/L of the required trolleys is calculated according to the width L of each trolley. For example, if v is 0.25m/s, t is 3s, and l is 0.2m, then the length of the cargo can be calculated to be 0.75m, and the number of required cars is 4.
In the step, the method also comprises the step of numbering the trolleys in the front, so that the number of the trolley to be selected can be determined according to the length of the goods. With reference to fig. 1, 2-5 cars are needed to start the contact with the cargo from the surface of the 2 nd car by calculating the number of cars to be 4 cars.
Determining a sorting position: the distance of the goods to the discharge opening 2 is determined. The target material distribution and discharge port 2 of the goods is determined by recognizing the recognition two-dimensional code arranged on the goods, and the distance from the material inlet to the target material distribution and discharge port 2 is calculated.
In this step, the number of vehicles passing by the first vehicle carrying the load when the first vehicle reaches the target material distribution outlet is calculated by increasing the count of the counter per vehicle passing by one by the distance D between the opposite photoelectric sensor 11 at the loading port and the emission sensor provided at the material distribution outlet 2 of the target, based on the width l of the vehicle, and based on the counter provided at the loading port. For example, D is 5m and l is 0.2m, so that after the counter counts 25 cars past, it can be determined that the car has reached the target feed discharge 2.
A material distribution direction control step: and the receiving sensor of the trolley determines the material distributing direction according to the signal of the transmitting sensor.
And calculating which trolleys need to be separated at the target material separating and discharging port 2 according to the distance D between the target material separating and discharging port and the opposite photoelectric sensor. For example, the material distributing belt of the trolley 4 at the material distributing outlet 2 of the target needs to be rotated in the forward direction, the forward rotation transmitting sensor 51 at the material distributing outlet 2 of the preset target is started, the first receiving sensor arranged on the body of the trolley 4 to be distributed receives the signal of the forward rotation transmitting sensor 51, and the material distributing belt 41 of the trolley 4 is controlled to push the goods out in the first direction; correspondingly, when the goods need to be pushed out in the second direction, the reverse rotation transmitting sensor 52 at the preset target material distribution outlet is turned on, and the forward rotation transmitting sensor 51 is in a closed state, so that the pushing out of the goods in the second direction is completed.
In some embodiments, the correlation photosensor is located in the area immediately adjacent to the loading port of the linear track section 31 to ensure accurate numbering of the required carts and to achieve more accurate delivery of the cargo to the corresponding material dispensing outlets.
Referring again to fig. 1, the number of required trolleys is 4 when the targeted material distributing outlet 2 is at the second outlet, the first trolley during loading of the goods is trolley No. 2, so that when 2-5 trolleys move the goods to the second outlet together, the forward rotation transmitting sensor 51 is turned on, the first receiving sensor of the trolley receives a signal to control the driving roller 410 of the trolley to rotate forward and push the goods out in the first direction.
In some embodiments of the present invention, the method further comprises a trolley numbering step performed in the preceding step, wherein the trolley numbering step is performed by numbering the trolleys and determining the serial numbers of the trolleys where each cargo stays; and the time of the trolley with the goods staying at the target material distribution outlet is calculated according to the distance between the goods feeding port and the corresponding emission sensor at the material distribution outlet 2, and after the trolley reaches the goods outlet, the corresponding emission sensor is opened, so that the sorting of the goods is completed. The determination step of the serial number of the trolley where the goods are stopped can be realized by continuously and circularly counting through a counter. With the width l of the trolley being 0.2m, the feeding speed v of the goods being 0.25m/s, and the number of trolleys 4 arranged on the whole circulation track being 100, in the first circulation, the counter has counted 20 trolleys 4, then the opposite-emitting photosensor 11 is shielded for 3s, and in the time period when the opposite-emitting photosensor 11 is shielded, the counter counts 4 trolleys, so that it can be determined that the number of trolleys where the goods stay is 21-24. After the counter counts up to 100, it is zeroed again and starts counting from 1.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the present invention is not limited thereto, and any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
