Push bottle mechanism

Abstract

The invention discloses a bottle pushing mechanism which comprises a push plate which is movably arranged on the inner wall of a bottle sending groove of a bottle sending star wheel, a bottle supporting plate arranged below the bottle sending groove of the bottle sending star wheel, a control device fixed to the bottle sending star wheel, and a drive device connected with the control device. A drive rod of the drive device passes through an elastic assembly in a controlled manner so that a bottle can abut against a fence after the bottle sending groove is subjected to elastic thrust, wherein the elastic assembly exerts the elastic thrust on the push plate. When the bottle is sent to a preset bottle discharging position, the bottle is disengaged from the fence and is pushed out under the action of the elastic thrust. According to the bottle pushing mechanism, the elastic thrust can be exerted on the bottle under the cooperation of the control device, the drive device and the elastic assembly, when the bottle is sent to the preset bottle discharging position, the bottle is disengaged from the fence under the action of the elastic thrust to be pushed out, the bottle can be sent out from the preset bottle discharging position accurately and rapidly, in addition, the bottle exploding rate can be effectively reduced through the elastic thrust, and meanwhile the structure is easy to maintain.

Description

Technical field [0001] The invention relates to a bottle pushing mechanism. Background technique [0002] The light inspection machine is a fully automatic light inspection equipment that detects the quality of bottled liquid medicines. The detected bottled liquid and solid medicines need to be sorted according to the test results and sorting standards, and the bottled liquid and solid medicines must be sorted at a high speed. The bottle is discharged from the conveying device to two or more channels respectively to enter the next process. [0003] At present, many methods of discharging bottles use manual sorting or automatic sorting, but they all have certain disadvantages: (1) The efficiency of manual sorting of bottles is low; (2) The screw discharging method and swing block (such as swing rod) are only used for sorting. The bottle can be discharged to dual channels, which cannot be used for multi-channel sorting; (3) The motor drives the crank and connecting rod mechanism to ...

AI Technical Summary

Problems solved by technology

[0003] At present, many methods of bottle output adopt manual sorting or automatic sorting, but there are certain defects: (1) the efficiency of manual sorting out of bottles is low; It can realize bottle output to dual channels, and cannot be used in multi-channel sorting occasions; (3) the motor drives the crank linkage mechanism to push the bottle, which requires the use of a motor, which increases the equipment cost, and the fixed reciprocating motion of the motor will also bring There is a certain probability of bottle explosion. In such a scheme, the movement of the motor is the main movement. Regardless of whether the bottle is squeezed at the bottle outlet, the bottle pushing rod driven by the motor will give the bottle an impact. The bottle at the outlet will If it is squeezed and the impact force transmitted by the motor to the bottle at the same time, there is a danger that the bottle burst rate will increase rapidly.

However, this improvement not only increases the complexity and manufacturing cost of the mechanism, but also inevitably restricts the actual bottle output speed due to the complexity of the movement of the action mechanism, making it difficult to meet the requirements of high-speed sorting of bottles; (5) negative pressure type The bottle sorting mechanism is equipped with multiple negative pressure channels to suck out the corresponding bottles with negative pressure. It can achieve high-speed and multi-channel sorting purposes during normal operation, but its insurmountable defects lie in: negative pressure manufacturing equipment, negative pressure channels The system is complex and costly; the working condition of the negative pressure channel must be smooth and clean, and small foreign objects (such as glass chips, etc.) will destroy the pressure balance and hinder the smooth suction of the bottle; correspondingly, the bottle body must also be kept smooth, and the outer surface The protruding part (such as a manufacturing defect forming a protruding point) will also hinder the smooth suction of the bottle and even cause broken bottles and glass chips to enter the negative pressure channel

According to the current broken bottle rate of 3 / 10,000, (calculated by 500 bottles per minute), it is usually forced to stop for inspection and cleaning for 2-3 hours every eight working hours, which seriously affects the efficiency.
