Woodpecker type bottle preform box filler and bottle preform box filling method thereof

Abstract

The invention discloses a woodpecker type bottle preform box filler. The bottle preform box filler comprises a bottle preform box, a PLC control device, a bottle preform conveying device, a hydraulictransmission device and an ultrasonic distance measuring sensor; the bottle preform conveying device is in a woodpecker shape and is controlled by the PLC control device and is used for conveying thebottle preforms to the bottle preform box; the bottle preform conveying device comprises a horizontal part, a slope part and a part shaped like a woodpecker head, the bottom end of the slope part is hinged to the horizontal part, and the top end of the slope part is fixedly connected with the part shaped like a woodpecker head; the hydraulic transmission device is controlled by the PLC control device and used for supporting and adjusting the inclination angle of the slope part; and the ultrasonic distance measuring sensor is fixed to the bottom end of the part shaped like a woodpecker head andused for measuring the distance between the ultrasonic distance measuring sensor and the uppermost layer of bottle preform in the bottle preform box and transmitting the vertical distance value to the PLC control device. The invention further discloses a bottle preform box filling method of the woodpecker type bottle preform box filler. The bottle preform box filler has the advantages of being stable in lifting, high in positioning precision and capable of reducing the bottle preform damage risk.

Description

technical field [0001] The invention relates to a preform packing machine and a preform packing method thereof. Background technique [0002] The existing woodpecker type box packing machine uses a pneumatic transmission and control device. The working principle of the pneumatic transmission is to use the air compressor to convert the mechanical energy output by the motor into the pressure energy of the air, and then control the control components and cooperate with the auxiliary components. Next, the pressure energy of the air is converted into mechanical energy through the actuator, so as to complete the linear or rotary motion and perform work externally. Due to the high compressibility of the air, it is difficult to achieve accurate speed control and high positioning accuracy, and the stability of the system is poor when the load changes. It is easy to cause problems such as inaccurate positioning of the woodpecker head and large lifting errors during operation. At the ...

Problems solved by technology

[0003] When the existing woodpecker-type box packing machine is in use, after each machine produces a full product box, workers need to move and replace the empty box, which requires the boxer to always pay attention to the situation of the product box and manually move and change the box, increasing The workload of the packing workers or sometimes the failure to replace them in time will lead to more products being scrapped and causing unnecessary losses, greatly reducing work efficiency

Although some brands of cartoning machines have automatic carton changing devices, their working mechanism is to change the direction of the horizontal conveyor belt so that the preforms fall into the hoppers on both sides of the conveyor belt, and then fall into the boxes through the lifting of the hoppers. During the process, the preforms have to go through multiple drops and bumps, which can easily cause damage to the preforms and lead to waste products
