In the modern textile industry, which pursues the ultimate efficiency and quality, a well-known Japanese-owned textile enterprise took the lead in breaking the situation and deployed an unmanned forklift (AGV) cluster system covering multiple scenarios, realizing the full-link automation from loom dropping to warehousing and then to cross-workshop (including outdoor) transportation. The project not only opened up key logistics nodes, but also reshaped the efficiency and reliability of grey cloth circulation with the ability of 24-hour uninterrupted operation and multi-vehicle intelligent collaboration.
Customer needs
1. Whole-process automation breakpoints:
It is urgent to open up the whole chain automation of the recycling of empty trays → automatic cloth dropping of looms, warehousing (including loading and unloading), warehousing and cross-workshop (to dyeing), so as to eliminate manual dependence, especially to overcome the traditional difficulty of outdoor long-distance transportation.
2. Double pressure on efficiency and cost
Manual handling is slow, time-consuming, costly, and error-prone, which has become a bottleneck for capacity improvement and lean management.
3. Security and stability challenges
The outdoor environment is complex and changeable, which puts forward extremely high requirements for the safety and operational stability of transportation equipment.
Solution
1. Grey cloth drop-stacking area of weaving workshop
When the weaving of a single roll of grey cloth is completed and the cloth needs to be dropped, the V05F forklift AGV is manually called, and the AGV arrives near the machine, and the AGV automatically drops the cloth and the cloth is completed; The weaving workshop automatically drops the cloth, and the AGV automatically transports the single roll to the cloth roll stacking area (near the corresponding pallet storage location of each machine) and transports the pallets out of the warehouse.
2. Grey cloth storage
When the M20OR omnidirectional stacking forklift AGV forklifts the pallet of the corresponding machine, the AGV pallet is automatically dropped, and when it rises to exceed the height of the pallet, the grey cloth pallet is overturned, and the grey cloth is automatically rolled down to the pallet by gravity.
3、Grey cloth out of the warehouse
When the grey fabric needs to be shipped out of the warehouse, the omnidirectional stacking AGV will be manually called to carry the grey fabric from the shelves in the grey fabric temporary storage area to the grey fabric outbound storage area for temporary storage, and the omnidirectional stacking AGV will return to the parking point/charging point to wait for the next handling task.
4. Long-distance outdoor handling
The V20T outdoor handling forklift AGV transports the grey cloth pallet to the storage temporary storage position in the waiting area of the dyeing workshop, and then the manual forklift in the waiting area of the dyeing workshop transports it into storage.
Key pain points
1. Reliability of outdoor long-distance transportation
This is the core challenge of the project, the forklift AGV needs to maintain millimeter-level positioning accuracy, stable navigation (such as fusion of laser SLAM and inertial navigation), safe obstacle avoidance and stable operation in an uneven or obstructed outdoor road environment, so as to ensure that the transportation of grey fabrics is foolproof.
2. Efficient collaboration of multiple vehicles in complex scenarios
A variety of models (drop forklift AGV, counterbalanced forklift AGV, pallet handling forklift AGV) are mixed in dense workshops, warehouses, outdoor passages and other scenarios, and the intelligent dispatching system needs to have strong real-time calculation, optimal task allocation and dynamic traffic control capabilities to avoid congestion and waiting.
3. Seamless integration with existing production systems
It is necessary to deeply connect with the original MES/WMS system and loom control system of the enterprise to ensure the automatic issuance of task instructions and real-time feedback of status, so as to realize the real synchronization of information flow and logistics.
Benefits
1. Leap in efficiency: 30%-50% increase in logistics timeliness
The AGV cluster operates 24 hours a day, and with the intelligent scheduling system, the cross-workshop transfer time of grey cloth is shortened to 1/3 of the original manual handling, and the transportation cycle from loom to storage is reduced by 40%.
2. Sharp reduction in costs: saving more than 2 million yuan in manpower and loss annually
The handling error rate is reduced to less than 0.1% (the original manual error rate is about 3%), which reduces the loss caused by grey fabric damage by 1 million yuan and saves about 1 million yuan in labor costs annually.
3. Lean management upgrade: data-driven full-link optimization
Warehousing and warehousing efficiency increased by 9 times (lock-in time reduced from 30 minutes to 5 seconds), and inventory turnover increased by 25%.
