Rice Bag Inspection Solution

Rice Bag Inspection Solution

Production Process

The automatic rice packaging line integrates multiple packaging machines for packaging, case sealing and palletizing. Mature automated lines adopt vision inspection to detect defective products and stop them from flowing into the market.

Defect Analysis

Printing & coding defects on rice bags: missing codes, duplicate codes, incorrect codes and other related defects.

Customer Pain Points

Defects may occur due to objective factors, including unexpected on‑site machine shutdowns, shape variations of packaging bags during production, and coding errors caused by human interference. Manual inspection incurs high labor costs and delivers unstable results. Therefore, an automated solution is required to address these issues.

Solution Design

Tight integration with OEM equipment. Lighting schemes are customized according to equipment conditions. The overall vision system parameters are configured based on actual equipment operation. Customized solutions and deep‑learning modules are deployed to resolve on‑site pain points。

Overall Solution Overview

  • ● Well‑planned on‑site cabling supports multi‑camera operation while eliminating cabling‑induced interference for reliable communication and inspection. The layout remains tidy and professional.

  • ● Photoelectric hardware triggering is implemented: trigger signals feed into the Inovance PLC, which routes signals onward to camera trigger lines.

  • ● All camera Ethernet cables terminate at Inovance switches to facilitate dedicated, independent image transmission.

  • ● Image processing is completed on a PC, which delivers inspection results to the Inovance PLC. The Inovance PLC passes signals to the customer‑hosted PLC through digital output points, removing the need for direct PC‑to‑customer‑PLC communication.

  • ● The 1‑to‑6 multi‑camera architecture maximizes hardware utilization, addresses field‑level challenges and delivers superior cost‑performance.

Woven Rice‑Bag Inspection Solution Overview

  •  The camera is mounted downstream of the ink‑jet printer. Images are captured through cut‑outs on clamping steel plates immediately after coding, to guarantee flatness at the printing area.

  •  Camera triggering for image acquisition takes place during product conveyance. The camera faces directly toward the coding zone; its height is adjustable to align the center of field‑of‑view with the target printing position as the coding location varies.

  •  Rejection mechanisms are customized for site‑specific conditions to ensure convenient on‑site operation.
