How to handle the deviation of conveyor belt of robot palletizer? Next, Shandong ellite Zhongshun intelligent palletizer will tell you the solution.
When the conveyor belt deviates, the belt pushes the vertical cone roller to deflect the seat fork fixed on the cone roller by an angle, and drives the cross pin to lean against the end face block of the side roller through the shifting pin, and the side roller is braked. The conveyor belt and its sliding friction make the roller frame rotate an angle around the vertical axis, so that the belt moves to the center.
The structure of the new type of powerful self-aligning roller frame group is similar to that of the traditional product, and the original rotary mechanism and girder are retained. The roller structure was changed into several sections, the vertical roller on both sides was changed into cone roller, and the seat fork for fixing the cone roller, the stop block at the end face of the roller and the cross pin under the cone roller were added.
The new type of idler is adopted. The existing idler structure is composed of pipe body, gasket, bearing seat, mandrel, bearing, inner and outer sealing ring, etc. Because of its large quantity and heavy weight, the connection reliability between bearing seat and pipe body is poor. Therefore, a new type of roller in the form of counter spiral spring can be used. Its structure is composed of bearing seat, counter rotating spring fixed on bearing seat, bearing, mandrel with hook head, sealing ring and retaining ring.
The irregular material falling on the conveyor belt in the feeding trough is easy to cause the deviation of the conveyor belt. Therefore, it is necessary to adjust the blanking point of the central dropping hopper to improve the deviation caused by the incorrect feeding point. Therefore, the baffle plates on both sides of the charging trough can be made to swing, and the position of the blanking point can be adjusted by adjusting the screw rod. When the conveyor belt is in normal operation, the vertical roller will not be pushed by the conveyor belt and reset under the action of spring, and the opposite side roller will be released automatically. This new type of powerful reversible self-aligning idler frame group overcomes the problems of small deflection moment and unsatisfactory effect of traditional alignment. It has good deflection adjustment effect, simple structure and easy maintenance.
