As multihead weighers become more prevalent across industries, many users face common issues due to their mechanical complexity and high automation. This article summarizes typical problems and professional solutions provided by Guangdong Kenwei to help enterprises maintain smooth operations.
With the rapid development of China’s economy, the demand for automated and precise quantitative packaging has surged. Multihead computerized combination weighers have become increasingly popular in food, chemical, and hardware industries due to their high efficiency and accuracy. However, being advanced machinery with intelligent controls, users may encounter various issues during operation.
To help resolve these concerns, Guangdong Kenwei Intellectualized Machinery Co., Ltd., a global leader in weighing and packaging systems, provides technical insight and professional guidance for several frequently encountered problems.
🔧 Issue 1: Request Signal Must Be Turned On for Next Batch?
Situation:
Users report that after disconnecting the request signal, the machine won’t start the next batch unless the signal is turned on again.
Solution:
This typically occurs when the request signal detection mode is incorrectly set to 0 or 1 (pulse falling edge mode). To fix this, enter the system settings and change the request signal detection mode to 2 or 3 (level-triggered mode). This ensures smoother operation and avoids manual intervention after each batch.
🥟 Issue 2: Inaccurate Weighing of Frozen Dumplings (470g on 10-Head Weigher)
Problem:
Customers notice significant discrepancies in weight when weighing frozen dumplings.
Cause & Fix:
High ambient temperatures can cause the dumplings’ surfaces to melt, leading to sticky hoppers and slower operation. Follow these steps:
-
Clean and air-dry the device thoroughly.
-
Concentrate the feeding material and set the number of free combinations to 15 (parameter: Start 1000).
-
Set the request signal detection mode to 0 (with memory).
-
Adjust the signal delay before discharge to ensure materials fully settle before weighing.
🛑 Issue 3: Machine Slows Down After One Hopper is Disabled
Scenario:
When a weighing hopper is disabled, the running speed of a 10-head weigher significantly slows.
Explanation:
The system is typically set to use 9 out of 10 hoppers for each combination. If one hopper is cleared, only 8 remain, reducing the number of valid combinations. The system will pause (wait) when it cannot find a valid combination within the set parameters.
Solution:
Enter the system and update the "number of combined hoppers" to 8. Additionally, repair the disabled hopper as soon as possible to restore optimal performance.
🍬 Issue 4: 14-Head Weigher Weighing 100g Candy Causes Empty or Overfilled Bags
Problem:
Users report receiving empty bags or excessive product in a bag during candy packaging.
Reason:
This usually happens when the discharge signal is sent before the material reaches the packaging machine. If there’s no combination available at the moment, the system may still trigger discharge, but the collecting hopper may be empty or unevenly filled.
Solution:
-
Adjust the delay value for the collecting and weighing hoppers.
-
Ensure material flow is even and consistent.
-
Verify signal synchronization between the weigher and packaging machine.
