Specifically, the multiple rows of the rotating rollers 4100 form a conveying surface with a wide input end and a narrow output end, and a central conveyor, and each row of the rotating rollers uses the center line X of the conveying surface as a symmetry axis.

As shown in fig. 1 and 2, the axes of two rollers 4110 positioned in the middle of each row of rollers 4100 are perpendicular to the center line X, and the other rollers 4120 are inclined toward the center line X to move the articles thereon toward the center line X, specifically, the other rollers 4120 positioned on the left side of the center line X are inclined toward the right side, and the other rollers 4120 positioned on the right side of the center line X are inclined toward the left side. All the rollers 4110 at the intermediate position form the first conveyance zone, the other rollers 4120 at the left side of the center line X form the second conveyance zone, and the other rollers 4120 at the right side of the center line X form the third conveyance zone.

Therefore, when the articles are conveyed on the rows of the rotating rollers, the articles move towards the central line direction of the central conveyor under the action of the rotating rollers, so that the articles on two sides can be gathered towards the middle.

As shown in fig. 3, the mounting position of each of the rollers 4100 is fixed, they are respectively mounted on the supports 4600 provided on the frame 4500, the rollers 4100 are connected to the support shafts 4610 of the supports 4600 through bearings (not shown), and the supports 4600 on which the rollers of each row are located are respectively provided on a separate mounting plate 4520 on the frame 4500.

As shown in fig. 1, the number of rows of the rotating rollers 4100 can be designed as required, preferably, the rotating rollers 4100 are 18 rows, the number of the rotating rollers in each row can be designed as required, preferably, the number of the rotating rollers in the 1 st row to the 8 th row is the same, the number of the rotating rollers in the 9 th row to the 14 th row is the same, the number of the rotating rollers in each row is 1 less than that of the rotating rollers in the 1 st row to the 8 th row, and the number of the rotating rollers in the 15 th row to the 18 th row is the same, and is 1 less than that of the rotating rollers in the 9 th row to the 14 th row; meanwhile, except the rotating rollers at the middle position, the adjacent rotating rollers are staggered one by one to form central lines.

As shown in fig. 1 and 2, the inclination angles of the two sets of rollers on both sides of the center line X can also be designed according to the needs, and in the preferred embodiment, the inclination directions of the other rollers in each row are kept at an angle of 30 ° or less, further preferably 5 ° to 25 °, further preferably 10 ° to 20 ° with respect to the center line, except for the intermediate roller 110, and all the rollers 4120 on the same side of the center line X are inclined in the same direction except for the intermediate roller in each row.

As shown in fig. 1 and 2, each of the rotation rollers 4100 is driven by a drive roller 4200 in contact with the tread surface thereof, and the drive roller 4200 is connected to a drive mechanism 4300 for driving the rotation thereof. The adjacent two rows of rollers are driven by a drive roller 4200 located between them.

The driving roller 4200 may be a round shaft, and since the other rollers are inclined except for the roller at the middle position, the driving roller 4200 and the wheel surface of the inclined roller can only be in point contact, which is obviously disadvantageous to the stability of the friction driving.

Therefore, in a more preferable manner, it is necessary to make the driving roller 4200 in line contact with each of the rollers 10 in a row of rollers, thereby securing driving stability. Specifically, as shown in fig. 2, the driving roller 4200 includes a main shaft 4210, a boss 4220 abutting against a wheel surface of each of the rollers 4100 is formed on the main shaft 4210, the boss 4220 includes a first circular table 4221 and a second circular table 4222, the second circular table 4222 is symmetrical to the first circular table 4221, and small ends of the second circular table 4222 are arranged back to back, so that one boss 4220 can drive two rollers with the same number in two adjacent rows of rollers, for example, a tapered surface of the first circular table 221 abuts against a wheel surface of a first roller (leftmost side) of the first row of rollers, and a tapered surface of the second circular table 4222 abuts against a wheel surface of a first roller (leftmost side) of the second row of rollers, so that one driving roller 4200 can drive two adjacent rows of rollers to rotate.

As shown in fig. 4 to 5, each of the driving rollers 4200 is rotatably provided on the frame 4500 by two bearings (not shown) and driven by a driving mechanism 4300, the driving mechanism 4300 comprises a motor 4310, the motor 4310 can be any feasible servo motor, stepping motor, brush motor, brushless motor, etc., the motor 4310 is connected to one end of the driving roller 4200 through a first transmission structure formed by a pulley 4320 and a timing belt 4330, that is, a motor shaft of the motor 4310 is connected to a pulley 4320, in order to protect and facilitate assembly of the motor 4310, the motor 4310 is connected to a pulley 4320 through an expansion sleeve (not shown), one end of the driving roller 4200 is connected to another pulley 4320, the two pulleys are connected to each other through a timing belt 4330, the timing belt 4330 is preferably a V-belt, but may be a timing belt having a boss on an inner surface thereof.

Of course, the transmission mechanism may be other possible structures, such as a gear transmission mechanism or a transmission mechanism composed of a chain and a sprocket.

In order to adjust the tension of the timing belt 4330, the motor 4310 is adjustably disposed on the frame 4500, so that a tension wheel can be omitted and the tension structure of the timing belt 4330 can be simplified. For example, a set of waist-shaped holes (not shown) extending in parallel are formed in the frame 4500, and the motor 4310 is fixed to the frame 4500 by a set of bolts and nuts passing through the waist-shaped holes.

More preferably, as shown in fig. 4, the motor 4310 is fixed to an adapter plate 4340, and the adapter plate 4330 is adjustably mounted on the frame and connected to an adjusting support mechanism for driving the frame to move and providing an upward supporting force. Specifically, a kidney-shaped hole 4341 is formed in the adapter plate 4340, a corresponding connecting hole is formed in the rack, the connecting hole may be a circular hole or a kidney-shaped hole, and the adapter plate 4340 is fixed to the rack by a bolt (not shown) passing through the kidney-shaped hole 4341 and a connecting hole rear connecting nut (not shown). Meanwhile, the bottom of the adapter plate 4340 includes a flange 4342, at least one adjusting screw 4350 is vertically disposed on the flange 4342, the adjusting screw is fixedly connected to the flange 4342 through a fastening nut 4360, and the adjusting screw 4350 is further adjustably fixed to a support plate 4510 on the frame 4500 through two adjusting nuts 4370. This structure not only enables the tensioning of the timing belt 4330 to be effectively achieved by the movement of the motor 4310, but also does not require an additional tensioning structure. Meanwhile, the motor can be effectively supported by the adjusting nut 4360, so that the shearing force applied to the fixing bolt for connecting the adapter plate 4340 and the rack is reduced, and the reliability and stability of the installation of the motor 4310 are effectively ensured.

In addition, each of the driving rollers 4200 may be connected to a driving mechanism 4300, which increases the number of power sources, which is obviously disadvantageous for reducing the equipment cost and the operation cost, and in a preferred structure, a plurality of the driving rollers 4200 are driven by a motor 4310, that is, as shown in fig. 4 and 5, adjacent driving rollers 4200 are connected to a second transmission mechanism formed by a timing belt 4380 and a pulley 4390, and the tensioning of the timing belt 4380 is achieved by providing a movable tensioning wheel, where the structure of the movable tensioning wheel is known in the art and will not be described herein. Of course, the transmission mechanism may also be a gear transmission mechanism or a transmission mechanism consisting of a chain and a chain wheel.

In addition, since the friction driving method is adopted, the driving roller 4200 is likely to cause abrasion of the rotary roller 4100 after long-time friction between the driving roller 4200 and the rotary roller, so that the driving roller 4200 is not sufficiently contacted with the rotary roller, and the driving effectiveness is affected, in a more preferable configuration, the driving roller 4200 or the rotary roller 4100 is provided in an elastic mechanism.

In one embodiment, for example, when the height of the axis of the driving roller 4200 is higher than the height of the axis of the rotating roller 4100, the driving roller 4200 applies pressure to the rotating roller 4100, at this time, the rotating roller 4100 is disposed on the elastic mechanism, specifically, as shown in fig. 3, the support 4600 includes a base 4620, a guiding shaft 4630 is disposed on the base 4620, the guiding shaft 4630 is perpendicular to the two side plates 4621 thereof, and extends to the outer sides of the two side plates 4621, an H-shaped floating seat 4640 is movably disposed on the support 4620, the two side plates 4641 of the floating seat 4640 are attached to the outer sides of the two side plates 4621 of the base 4620, a vertically extending sliding slot or a kidney-shaped hole is formed on the two side plates 4641 of the floating seat 4640, the guiding shaft 4630 is disposed in the sliding slot or kidney-shaped hole and is non-rotatable therebetween, a torsion spring 4650 disposed between the floating seat 4640 and the base is further sleeved on the periphery of the guiding shaft 4630, one end of the torsion spring 4650 abuts against the floating seat 4640 and is normally in a pressure-deformed state. Therefore, when the roller 4100 is worn, the reaction force of the torsion spring 4650 when it is restored to its original state can drive the floating mount 4640 to move upward, so that the roller 4100 is moved upward to be kept in engagement with the driving roller 4200.

In another embodiment, as shown in fig. 6, the H-shaped floating seat 4640 may be rotated around the guiding shaft 4630 to adjust the position of the upper rotating roller 4100, in which the driving roller 4200 may be located at the middle position of the two rows of the rotating rollers 4100, the guiding shaft 4630 is a circle, the floating seat 4640 is in a tilted state in a normal state, and the torsion spring 4650 is kept in a compressive deformation state under pressure. When worn, the reaction force of the torsion spring 4650 drives the floating seat 4640 to rotate around the guide shaft 4630, i.e. the left floating seat rotates clockwise, and the right floating seat rotates counterclockwise, so that the roller on the floating seat is kept in fit with the driving roller.

In yet another embodiment, if the axis of the driving roller 4200 is located below the axis of the rotating roller 4100, the driving roller 4200 exerts an upward lifting force on the rotating roller 4100, and the driving roller 4200 is disposed on the elastic mechanism, which may refer to the structure disclosed in application No. 201711324626.8.
