Description

Technical Field

[0001] The utility model belongs to the technical field of roller conveying and relates to a roller conveying device. Background Art

[0002] As the name suggests, roller conveying uses rollers as the conveying medium to transport boxed objects, cylindrical objects or plate-shaped objects.

[0003] At present, the common roller conveying devices on the market mainly include a frame, multiple rollers located on the frame, and motors, chains or bevel gears for driving the rollers to rotate; when conveying, the object to be conveyed is first placed on the roller, and then the roller rotates to convey the object forward. If a cylindrical container is conveyed, a plate (such as a steel plate) is usually placed at the bottom of the roller first, and then the cylinder is placed on the plate, so that the position stability of the cylinder can be guaranteed to prevent it from tipping over. In practice, it is found that if the cylinder is filled with fluid or the height is high (the center of gravity is high), if the roller rotates too fast or stops too quickly, it is easy to cause the cylinder to tip over or spill, but if the roller rotates slowly or stops slowly, it is easy to cause low efficiency of conveying and poor use effect.

At this time, the support plate and the object continue to move forward under the force of inertia.

[0044] The utility model provides a roller conveying device. When conveying an object, the support plate 4 is first placed on the driving circle 3, wherein both sides of the support plate 4 are supported by a plurality of support circles. Therefore, even if the support plate 4 is separated from the driving circle 3 at the upstream end during the process of being supported and conveyed forward, the position stability of the support plate 4 and the object on the support plate 4 can be well maintained. Then the driving mechanism drives the roller 2 to rotate. When the support plate 4 and the object start, the support plate 4 and the object still have the effect of staying in place due to inertia. Therefore, at this time, relative sliding can occur between the driving circle 3 and the driving roller 2, that is, the acceleration of the support plate 4 when starting is small, and the speed can be increased slowly until it increases to a certain extent. At this time, the driving circle 3 located below the support plate 4 does not slide relative to the driving roller 2, and the speed of the support plate 4 reaches the maximum value. Similarly, before the support plate 4 and the object are transported to the designated position, the speed of the driving roller 2 slows down or stops rotating. At this time, the support plate 4 and the object continue to move forward under the force of inertia. At this time, the driving ring 3 can still rotate relative to the driving roller 2, thereby slowly slowing down the speed of the support plate 4, and making the support plate 4 slowly reduce its speed, and finally stop stably; the illustration in this application is only one unit of the conveying device, and in actual use, multiple units will be connected end to end and used; at the same time, after stopping, the downstream end of the support plate 4 is still supported by the driving ring 3 to prevent the support plate 4 from detaching from the bracket 1. The present application is mainly suitable for objects on the support plate 4 that are half-full of fluid, or objects with poor stability such as high height or high center.

[0045] Among them, in actual use, the more unstable the object is, the easier it is for the drive ring 3 and the drive roller 2 to rotate relative to each other, that is, the "set pressure" requires a lower value; on the contrary, if an object is more stable, it is more difficult for the drive ring 3 and the drive roller 2 to rotate relative to each other, or even no relative rotation is required. Therefore, in actual transportation, it is also necessary to adjust the relative rotation difficulty between the drive ring 3 and the drive roller 2 according to the object to be transported; if it is necessary for the drive ring 3 and the drive roller 2 to rotate relative to each other more easily, after rotating the adjusting bolt 11 through the operating hole 12, the pressure between the adjusting bolt 11 and the adjusting ring 9 is reduced, so that the pressure between the adjusting ring 9 and the stabilizing part 6 is also reduced, so that the drive ring 3 and the drive roller 2 can be easily rotated (if the adjusting bolt 11 is removed, the interaction force between the drive ring 3 and the drive roller 2 is very small, and the size of the interaction force between the two is almost adjusted by the adjusting bolt 11 in actual use).

[0046] During the adjustment process, the worker can also insert the force measuring rod into the force measuring hole 13, and rotate the driving ring 3 through the force measuring rod while keeping the driving roller 2 from rotating, and judge whether the friction between the driving ring 3 and the driving roller 2 is appropriate at this time, so as to achieve the purpose of rapid adjustment. During use, the anti-rotation part 10 on the outside of the adjustment ring 9 is inserted into the anti-rotation hole 8, so that the adjustment ring 9 cannot rotate relative to the driving roller 2, so that the friction force can be stably applied to the stabilizing part 6. The driving roller 2 and the driving ring 3 are engaged through the stabilizing groove 5 and the stabilizing part 6, so that the connection stability between the driving ring 3 and the driving roller 2 can be guaranteed.

[0047] During the process of transmitting objects, the driving motor 29 drives the support rod 26 at the upstream end to rotate, and the first support rod 26 and the second support rod 26 are transmitted through the transmission wheel 27 (preferably a sprocket) and the transmission belt 28 (preferably a chain), and the second support rod 26 and the third support rod 26 are also transmitted through the transmission wheel 27 and the transmission belt 28. Similarly, all the driving rollers 2 on the same side can rotate in the same direction and at the same speed through one driving motor 29; and the two support rods 26 at the upstream end are connected by a transmission rod 30, so one driving motor 29 can drive all the driving rollers 2 to rotate, or drive all the driving rollers 2 in the same unit to rotate.

[0048] When the support plate 4 is supporting an object, its two ends are movably pressed against the inner side of the limiting portion 14 by the drag-reducing balls 15, so that the position stability of the support plate 4 can be maintained; secondly, its bottom is supported by the auxiliary wheels 18, which can further improve the position and shape stability of the support plate 4, so that the transmission of the object can be carried out stably.

[0049] When conveying objects, the longitudinal limiting strip 20 and the transverse limiting strip 21 form a tic-tac-toe shape, and the space in the middle can be used to limit the container of the object, such as a paint bucket, a chemical bucket, or an explosive bucket, thereby improving the position stability of the container. After the container is placed, the transverse limiting strip 21 and the longitudinal limiting strip 20 respectively contact the bottom of the container on the outside to prevent the container from sliding off the support plate 4; at the same time, the transverse limiting strip 21 also has a certain elasticity, which can play a buffering role to a certain extent.

[0050] Since different containers have different sizes, the spacing between the longitudinal limit bar 20 and the transverse limit bar 21 needs to be adjusted; when adjusting the position of the longitudinal limit bar 20, it is only necessary to remove the positioning bolt 22, move the longitudinal limit bar 20 to a suitable position, and then thread the positioning bolt 22 with the positioning hole 19 at the corresponding position; when adjusting the position of the transverse limit bar 21, it is only necessary to engage the first engaging groove 24 from top to bottom at the position of the corresponding longitudinal limit bar 20, and at the same time, the second engaging groove 25 is also engaged on the other longitudinal limit bar 20, and at the same time, both sides of the transverse limit bar 21 are limited by the adjusting part 23, so that containers of different quantities or models can be limited, and the use effect is better.

[0051] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
