Background
With the continuous promotion of pharmaceutical factories to the medicine packaging capacity, the packaging requirements of pharmaceutical factories can be met only by the packaging equipment with higher and higher speed. Aiming at the conveying problem of the punched medicine plate of the high-speed blister packaging machine, the traditional single-channel conveying belt conveying can not meet the conveying condition of the medicine plate. Along with the die-cut quantity of per minute medicine board constantly increases, the medicine board quantity that the conveyer belt per minute was carried also constantly increases, and under the certain condition of conveyer belt linear velocity, the increase of medicine board quantity can bring certain pressure for carrying undoubtedly, and the emergence of the condition of finally probably leading to the folded sheet leads to the medicine board to carry unstablely.
Especially, under the on-line state, when the lower extreme equipment was carried to the bubble cap plate, because the speed is too fast, the single track butt joint can cause the jam, feeding unstability scheduling problem, great influence the production efficiency of baling line.
The high-speed packaging line can adjust the typesetting of the medicine plates in the primary design stage, so that the medicine plates can be directly conveyed in two ways when being punched as far as possible, and unstable factors caused by single-way conveying are reduced. However, more times, the punching mode of the medicine plate is specified by a customer, after punching, the medicine plate is placed on the conveyor belt by the suction plate manipulator and conveyed to the next equipment, in order to solve the problem of instability of single-channel conveying, a servo plate pulling device is usually carried out on the conveyor belt at the rear end after the medicine plate is placed on the conveyor belt, and the single-channel medicine plate is conveyed in a channel-by-channel manner. As shown in figure 1, the butt joint inlet 22 is in butt joint with the front-end conveying belt, and the pulling piece 23 repeatedly swings left and right under the action of the pulling piece driving motor 24, so that the purpose of conveying the conveyed medicine plates on two conveying belts in a poking mode is achieved, when the pulling piece 23 swings left, the medicine plates enter the first conveying belt 25 channel, and when the pulling piece 23 swings right, the medicine plates enter the second conveying belt 26 channel, so that the effect of single-channel shunt conveying is achieved.
However, the above-mentioned conventional conveying and distributing mechanism has the following disadvantages: 1. a shunt conveyor belt needs to be installed in a longer workshop length; 2. the servo swing frequency is too high, and the medicine plate is unstable when being pulled; 3. the phenomenon of medicine clamping is easy to occur; 4. the phenomenon that the medicine board is pulled over easily occurs.
