Problems solved by technology

[0007] 1. Low rejection rate
In the prior art, the single-chip rejection pulse signal with the number of dies as the input variable has low resolution, which limits its applicable maximum tablet production speed (the single-discharge model does not exceed 140,000 tablets per hour), and the single-chip The structure of the hole nozzle and the control of the single electromagnetic reversing valve will cause the movement state of the waste film to be unstable before entering the recycling channel, which cannot meet the higher requirements of single-chip rejection and continuous two-piece or multi-piece rejection, resulting in waste The probability of mixing in qualified products is high, which affects the quality of tablets;

Embodiment 1

[0041] As shown in Fig. 1, upper and lower eccentric shafts 19 and 20 are respectively arranged on the base 29 and the support block 15 of the tablet press; upper and lower main pressure wheels 21 and 22 are respectively arranged on the upper and lower eccentric shafts 19 and 20, Cooperating with the upper and lower guide rails 31 and 32 respectively, the upper and lower punch rods 23 and 24 of each pair of dies are controlled to perform relative reciprocating motion, and the tablet is pressed into shape in the middle die 30 .

[0042] As shown in Figures 1, 2 and 4, the single-chip rejecting device of the high-speed rotary tablet press of this embodiment includes: a central control unit, a tablet weight detection mechanism, an advanced disc assembly 1 arranged on the main motor 17 of the tablet press, The output tray combination 2 and the pneumatic reject system 3 are arranged under the turntable of the tablet press.

[0043] The central control unit is a programmable logic c...

Embodiment 2

[0059] On the basis of Embodiment 1, the advanced disk combination 1 of this embodiment can also have the following deformations:

[0060] The leading disc assembly 1 includes: a compensation sensor 7 and a compensation code disc 6 arranged on the output shaft of the main motor 17 .

[0061] The compensation code wheel 6 is provided with 50 counting holes evenly distributed on a circumference. The number of punches and dies of the tablet press is 55.

[0062] The compensation sensor 7 includes an optical signal transmitter fixedly arranged on one side of the compensation code wheel 6 and an optical signal receiver fixedly arranged on the other side of the compensation code wheel 6 and connected to the central control unit. The straight line where the optical signal transmitter and the optical signal receiver are located is perpendicular to the circumference where the counting holes are located, so as to generate the compensation pulse signal when the compensation code wheel 6...

Abstract

The invention relates to a single-chip waste-rejection device of high-speed rotary performing machine and the working method. The device comprises central control unit, chip-weight measuring mechanism for recording main pressure values of all dies of performing machine by the central control unit, yield disk combination set under the rotary table of performing machine and generating counterpoint signals corresponding with main pressure actions of all dies, and pneumatic waste-rejection system. The device also comprises advance disk combination set on main electromotor of performing machine and generating compensation pulse signal corresponding with angle speed of output shaft of main electromotor. The central control unit estimate if waste-rejection program runs according to all main pressure values. When the waste-rejection program runs the central control unit calculates the time point when die with waste chip runs to the nozzle position of pneumatic waste-rejection system as the performing machine runs by said compensation pulse signals and counterpoint points and touches pneumatic waste-rejection system off at the time point. Waste-rejection accurate ratio of device is high and adaptability is good.

Description

technical field [0001] The invention relates to a single-chip rejecting device of a high-speed rotary tablet press used in the pharmaceutical machinery industry and its working method, in particular to a pharmaceutical device for removing waste tablets during the tablet pressing process of the tablet press. Machinery and its working methods. Background technique [0002] The working principle of the high-speed rotary tablet press to press powdery and granular raw materials into tablets is that the main motor drives the turntable to rotate through the transmission mechanism (that is, the pulley and the worm gear pair). Under the cooperation of the upper and lower guide rails, the reciprocating motion of the upper and lower punches is controlled, and the cycle action is completed: filling material-quantitative-pre-pressing-main pressing-discharging. [0003] Regarding the high-speed rotary tablet press, see: a kind of rotary tablet press disclosed in Chinese patent document C...
