Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0023] like Figures 1-3 As shown, in one embodiment of this utility model, the differential roller conveyor 100 includes a support 10, multiple rollers 20, and a power source 30. The support 10 includes a fixed support 11 and a movable support 12, with one end of the movable support 12 rotatably connected to the fixed support 11. The rollers 20 are mounted on the support 10 and form a conveying surface for conveying medicine boxes. Some rollers 20 are mounted on the movable support 12, and the remaining rollers are mounted on the fixed support 11. Excluding the portion covered by the movable support 12, the multiple rollers 20 mounted on the movable support 12 are located at the two rollers 20 on the fixed support 11. Figure 1 The movable support 12 is located between 20A and 20B in the fixed support 11, not at the end of the transmission surface. The power source 30 is connected to and drives the other end of the movable support 12 to move up and down.

[0024] In practical operation, when the first medicine box moves onto the rollers 20 at both ends of the movable support 12, that is, when the front end of the medicine box moves along the conveying direction onto the roller 20A at the rear end of the movable support 12, the power source 30 drives the other end of the movable support 12 to move downwards. At this time, the first medicine box continues to move backwards, while the subsequent medicine boxes move onto the rollers 20 on the movable support 12 under the action of gravity and are blocked by the rollers 20A, preventing them from moving backwards. The subsequent medicine boxes are also blocked by this medicine box and cannot move. After the first medicine box has moved backwards a certain distance, the power source 30 drives the other end of the movable support 12 to move upwards. At this time, the conveying surface is restored, and the subsequent medicine boxes can continue to move backwards. Through the cooperation of the movable support 12 and the power source 30, the medicine boxes passing through the movable support 12 have a stable and uniform interval, which helps with manual or mechanical sorting at the rear and prevents accumulation.

[0025] It is easy to think that the output interval of the power source 30 can be adjusted to adjust the distance between the rear medicine boxes, and the flexibility is higher. The output interval of the power source 30 can be manually controlled in real time, or the fixed interval can be set by program, of course, it can also be adjusted in real time by visual or other detection system, and the embodiment is not limited.

[0026] Specifically, the fixed support 11 includes a base 111, and two first mounting plates 112 fixed to the base 111 and parallel to each other, and the two ends of the partial roller 20 mounted on the fixed support 11 are connected to the two first mounting plates 112. The movable support 12 includes two second mounting plates 121 respectively rotationally connected to the two first mounting plates 112, and a connecting plate 122 connected to the other end of the second mounting plate 121, and the two ends of the partial roller 20 mounted on the movable support 12 are connected to the second mounting plate 121, and the power source 30 is connected to the connecting plate 122.

[0027] Preferably, to avoid interference with the transmission of the medicine box, the two second mounting plates 121 are arranged outside the first mounting plate 112. Because they are arranged outside, the length of the roller 20 is uniform, so the connecting shaft between the roller 20 and the second mounting plate 121 is relatively longer, and therefore a long slot 1121 opening downward is formed on the two first mounting plates 112. When the power source 30 drives the other end of the movable support 12 to move upward, the connecting shaft can move into the long slot 1121, so that the roller 20 mounted on the movable support 12 can move to be flush with the roller 20 on the fixed support 11, thereby restoring the transmission surface of the medicine box. Secondly, the long slot 1121 can also prevent the roller 20 from moving upward too much to ensure the stability of the transmission.

[0028] Of course, after the long slot 1121 is formed on the first mounting plate 112, the second mounting plate 121 can also be arranged in the long slot 1121, that is, the second mounting plate 121 can be embedded in the long slot 1121 when the power source 30 drives the movable support 12 to move upward, and at this time the first mounting plate 112 and the second mounting plate 121 are in the same plane.

[0029] Preferably, the two second mounting plates 121 are connected by a reinforcing rib 123 to improve the overall stability of the movable support 12. And to avoid affecting the transmission of the medicine box or the operation of the roller 20, the reinforcing rib 123 is arranged on the other side of the roller 20, that is, the bottom of the movable support 12. For example, in Figure 3 , the bottom of the second mounting plate 121 is provided with two reinforcing ribs 123, and the two reinforcing ribs 123 are arranged obliquely to cover the entire area of the movable support 12, further improving the stability.

[0030] In the embodiment as shown in Figure 1 , one of the rollers 20( Figure 1The roller 20B is connected to both the first mounting plate 112 and the second mounting plate 121. The roller 20B also serves as the rotation axis between the second mounting plate 121 and the first mounting plate 112. Therefore, there is no need to add an additional pivoting structure between the first mounting plate 112 and the second mounting plate 121, which further simplifies the structure, improves stability and reduces costs.

[0031] In this embodiment, the differential roller conveyor 100 can be a mechanically driven conveyor line, meaning the rollers 20 are mechanically driven to transport the medicine boxes. Alternatively, the differential roller conveyor 100 can also be a conveyor line that relies on the gravity of the medicine boxes for self-transportation, for example... Figures 1-3 In the middle, the bottom of the base 11 is provided with height-adjustable support legs 113. By adjusting the support legs 113 on different bases 11, an inclined transmission surface is formed on the roller 20. Without the aid of mechanical drive to rotate the roller 20, the medicine box can move on the roller 20 by its own weight. The entire differential roller line 100 can work with only one drive mechanism, the power source 30, which further reduces manufacturing and operating costs.

[0032] Preferably, a rotatable third mounting plate 114 is installed on the top of the base 11, and the first mounting plate 112 is fixed to the third mounting plate 114. The third mounting plate 114 is used to adjust the angle of the fixed bracket 11 in conjunction with the support leg 113 and the third mounting plate 114, and to increase the contact area with the bracket 11, thereby improving stability.

[0033] In such Figure 1 In the embodiment shown, the third mounting plate 114 is provided with mounting holes 1141 and arc-shaped holes 1142. Correspondingly, the base 11 is provided with two screw holes (not shown) that are coaxial with the mounting holes 1141 and arc-shaped holes 1142 respectively. The third mounting plate 114 can be fixed to the base 11 by bolts, and the angle of the third mounting plate 114 can be adjusted by the arc-shaped holes 1142.

[0034] Preferably, to prevent the medicine box from slipping during transport, the top of the first mounting plate 112 is higher than the medicine box transport surface, which can provide a barrier when the medicine box moves in other directions, further improving stability.

[0035] In one embodiment, the power source 30 is a cylinder, but other power output devices can also be selected, and this embodiment is not limited. Since the movable bracket 12 and the fixed bracket 11 are rotatably connected, when its other end moves in the vertical direction, it will generate a certain displacement in the horizontal direction. Therefore, the cylinder is pivotally connected to the mounting bracket 13, and its output end is also rotatably connected to the connecting plate 122, so that the cylinder can adjust its own posture to cooperate with the movement of the connecting plate 122 when outputting.

[0036] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
