Description

Roller way pushing device

Technical Field

The utility model relates to a roller way conveying device, in particular to a roller way pushing device, and belongs to the technical field of mechanical conveying devices.

Background

In the existing barrel cake roller way conveying system, for two serial roller ways with power, as long as reasonable spacing and power are set, the barrel cake can be easily conveyed from one roller way to the other roller way, or the barrel cake can be stopped at any appointed position.

However, when the front roller way is powered and the rear working table is an unpowered roller way or a fixed plane, the barrel cake can not be driven to advance continuously in theory after leaving the last roller of the front roller way. Because the power of the front roller way (usually a motor) is required to overcome the friction force between the barrel cake and the workbench which is larger than the friction force of the roller besides the friction force between the barrel cake and the roller in the transition process from the front roller way to the rear workbench, the required transfer and conveying can be completed. Otherwise, the conveying process cannot be completed, and the roller table and the motor may be damaged. If the front roller way is equipped with enough power to overcome all friction, not only is the cost increased, but also most of the time is wasted power, especially when the weight of the transport bucket cake is heavy.

As can be seen from the search, the chinese patent document with application number 201921332151.1 discloses a roller way pushing device, which comprises a track supported on supporting legs, wherein the track is composed of a group of sequentially arranged power driven rollers which are driven from an inlet to an outlet, and the rollers comprise a plurality of long rollers at the inlet section and a plurality of pairs of short rollers with aligned axes at the outlet section; the lifting pushing device comprises a lifting pushing plate driven by a pushing device arranged at intervals between the paired short rollers, the pushing device comprises a linear air cylinder extending along the conveying direction, a rotary air cylinder is arranged on a sliding block of the linear air cylinder, a rotating arm of a rotating shaft of the rotary air cylinder is hinged with the lower end of a lifting rod of which the upper end is provided with the pushing plate through a connecting rod, and the lifting rod and a sliding sleeve arranged on a connecting plate assembly form a vertical moving pair.

The technical innovation of the pushing roller way can realize that the barrel cake is pushed out of the current roller way to the next station, but the barrel cake is difficult to be pushed to a proper position stably and reliably, and meanwhile, the specific information of the barrel cake cannot be measured.
