Design of the motion law of the pusher slider of the cartoning machine
In combination with the problems encountered in the actual production of the enterprise, the following work requirements are proposed for the above-mentioned cartoning machine:
1, the push is smooth. In order to improve production efficiency, the pusher slider of the cartoning machine (https://www.hlyj.net/Products/72/) must first approach the material conveying line at a large speed, such as plastic wrap, bag biscuits and In the case of bagged toys, etc., considering the material properties of different pushed products, the pushing motion curve should be as continuous and smooth as possible to ensure a smooth pushing process and a small impact.
2, the box location is accurate. In the process of pushing the material, the product with higher advancing speed and the baffle on the side of the carton conveying rail perpendicular to the pushing direction tend to collide rigidly, causing the product to bounce back to the pushing track, making the product incomplete. Enter the paper tray and deviate from the correct loading position. In order to prevent the push product from rebounding, it is required that the push block can still stay for a certain period of time after pushing the product into the paper box, thereby ensuring that the product is accurately inserted into the box without the card machine.
3, the quick return feature. It is required that the returning stroke of the pushing mechanism is faster than the pushing stroke, and the pushing cycle is shortened.
As shown in Fig. 4, the pushing stroke is 380 mm - 390 mm, and the pushing mechanism has a motion period of 2 S.
In order to meet the above requirements, considering that the acceleration curve of the fifth-order polynomial motion has no abrupt change, and its amplitude is small, it can effectively avoid the rigid impact and the flexible impact 10.7], and the push-slip is designed as shown in Fig. 1. Block motion regular curve. The motion law consists of three motion curves, namely 0-1s, 1.3s-2s is the 3-4-5 polynomial motion law, and 1s-1.3s is the linear motion law.
