Elevator guide rail automatic stop and discharge device

Abstract

The invention discloses an automatic material blocking and feeding device for elevator guide rails. The automatic material blocking and feeding device comprises a longitudinal rack and a transverse rack, a transverse conveying belt is arranged on the transverse rack, a longitudinal conveying roller is arranged on the longitudinal rack, transverse supports are arranged on the front side and the rear side of the transverse rack below the transverse conveying belt respectively, a pair of lower guide rails is arranged on each transverse support, movable racks pushed by translation air cylinders to move are arranged on the lower guide rails, a lifting air cylinder is arranged on each movable rack in the vertical direction, a supporting head is arranged on a piston rod of each lifting air cylinder, the two supporting heads form a guide rail containing platform, material blocking blocks and approach switches are respectively arranged at the positions, above and below the transverse conveying belt, of the transverse rack, after the elevator guide rails are blocked, one single guide rail abutting against the material blocking blocks is exactly located over the approach switches, the piston rods of the lifting air cylinders stretch out, the guide rail over the approach switches can be supported, and the piston rods of the translation air cylinders stretch out to enable the supported guide rail to move to the longitudinal rack. The automatic material blocking and feeding device has the advantage of being high in work efficiency.

Description

technical field [0001] The invention relates to an automatic blocking and discharging device for elevator guide rails. Background technique [0002] In the production process of elevator guide rails, it is generally possible to move several elevator guide rails placed side by side on the horizontal conveyor belt one by one through the elevator guide rail automatic blocking and discharging device to the place where only a single elevator guide rail can be conveyed vertically. on the longitudinal conveyor belt. The structure of the elevator guide rail automatic stop and discharge device currently used is as follows: it includes a longitudinal frame and a horizontal frame that are arranged side by side, and a horizontal conveyor belt that can transport the elevator guide rails horizontally from left to right is arranged on the horizontal frame. The belt crosses the longitudinal frame and is located above the longitudinal frame. A pair of mounting plates distributed front and r...

AI Technical Summary

Problems solved by technology

The disadvantage of this elevator guide rail automatic stop and discharge device is: after the elevator guide rail is blocked by the material stop block, the two discharge arms are rotated upward around the connecting shaft, and the single elevator guide rail located directly above the first proximity switch is pushed upward. Then, the ejected single elevator guide rail will be located on the left side of the material stop block, while the rest of the elevator guide rails are still blocked by the material stop block and located at the stop block. Right side of the block, as the transverse conveyor belt moves the single elevator rail on the left side of the block to the left to the longitudinal rack, the rest of the elevator rails on the right side of the block also move to the left , but due to the blocking of the material stopper, the blades of the adjacent elevator guide rails on the right side of the material stopper are easily stacked together. For the elevator guide rails where these blades are stacked together, the discharging arm cannot complete the single At this time, manual correction is required, which greatly reduces the work efficiency; and because the horizontal conveying frame needs to cross the longitudinal frame, the overall occupied area of ​​the blocking and discharging device is increased, and the production cost of the enterprise is increased.
