A hollow guide rail foam strip filling device and working method

Abstract

The invention discloses a hollow rail foam strip stuffing device and a working method. The device includes a bracket, a foam crate arranged on the bracket, and a cutting and shifting part arranged at one end of the bracket for cutting the foam strip; the bottom of the foam crate is arranged There is a foam crate conveying part for controlling the horizontal and vertical movement of the foam crate; the other side of the foam crate is provided with a step pushing part for pushing the foam strip into the cutting and shifting part; one part of the step pushing part A foam strip pushing part is provided on the side for pushing the cut foam strip into the hollow elevator guide rail. The foam strip pushing part is installed on the bracket and is perpendicular to the cutting and shifting part in space. The whole process of cutting, chamfering and stuffing in the present invention is fully automated, the labor intensity of workers is small, and the production efficiency is high; the whole process of moving positioning, cutting, chamfering and stuffing can ensure the accurate posture of the foam strip and ensure that the foam strip can be inserted into the hollow In the elevator guide rail, the reliability of the system is guaranteed.

Description

technical field [0001] The invention relates to a hollow elevator guide rail assembly production equipment, in particular to a hollow guide rail foam strip filling device and working method. Background technique [0002] The elevator guide rail is an elevator component composed of steel rails and connecting plates. Existing guide rails can be divided into three types: T-shaped, L-shaped and hollow from the cross-sectional shape. Since the hollow elevator guide rail has a series of advantages such as light weight and material saving, it is widely used. Hollow elevator guide rails are generally filled with foam inside to make them have the performance of sound insulation, noise reduction and shock absorption. Most of the existing foam filling is carried out manually. In this kind of operation, workers need to repeat the same mechanical action all the time. Not only is the labor load large, the work efficiency of the workers is low, and the product quality cannot be guarantee...

Problems solved by technology

[0006] Further, in order to prevent the foam strips from being difficult to transport due to large shape errors and inability to maintain accurate posture during the grasping process, a step-by-step push component is used instead of a traditional manipulator to transport the foam strip; the step-by-step push The components include Y-direction motor, No. 2 drive plate, No. 2 polished rod, No. 2 lead screw, support base plate, No. 2 push head and No. 2 push rod; the support base plate is installed on the bracket, and the support base plate is arranged in parallel No. 2 polished rod and No. 2 lead screw, the No. 2 driving plate is installed on the No. 2 polished rod through a linear bearing, and is connected with the nut installed in cooperation with the No. 2 lead screw, and the Y-direction motor is fixedly installed on the supporting base plate The output shaft of the Y-direction motor is connected to one end of the No. 2 lead screw through a coupling transmission. One end of the No. 2 push rod is installed on the No. 2 drive plate, and the other end is installed on the support base plate through a linear bearing. , the end of the No. 2 push rod is provided with a No. 2 push head having the same cross-sectional shape as the foam bar. When the Y-direction motor rotates, the No. 2 screw drives the No. 2 drive plate and is installed on the No. 2 drive plate. The No. 2 push rod on the top moves along the No. 2 polished rod; due to the use of the push head with the same cross-sectional shape as the foam strip, the foam strips stored in the foam crate can move under the action of the push rod, and there will be no movement during the movement. Affected by external force, and the running trajectory of the foam strip is always on a straight line, which reduces the deviation during operation and ensures that the foam strip always maintains an accurate posture
