Logistical Automation Inside Factories

The manufacturing industry was an early adopter of optimization through automation. Within the industry, food and pharmaceutical manufacturers have to abide by much stricter rules and regulations, such as the HACCP, GMP, or GDP, compared to what other product manufacturers must follow. While the rules have their differences, the below must be heeded when considering implementing automated material handling systems.

  • Minimization of the emission, dispersal, and build-up of dust.
  • Ease of cleaning and maintenance.
  • Prevention of cross-contamination.
  • Prevention of human error.

At Daifuku, our material handling systems take the above points into account and provide our customers with optimized, labor-saving processes, such as raw material storage, work-in-progress storage, and finished product storage, as well as the transportation between production and storage.

Logistical automation inside factories

Automation of Raw and Packaging Material Arrival and Storage

Raw and packaging materials that have arrived from suppliers are inspected and then stored in an AS/RS. Afterward, each product lot is inspected. Until a lot is given a pass, it is prevented from moving to the manufacturing process. In cases where the manufacturing process takes place across multiple floors, the AS/RS also acts as an elevator.

(1) Raw and packaging materials are inspected upon arrival and then stored. (2) Raw materials are sampled and are prevented from being moved to production until they receive a pass. (3) Materials are quickly supplied based on the needs of the production line.

If a particularly clean environment is necessary (such as for pharmaceuticals), depalletizing robots will separate each case and individually send them through an air shower. Afterword, a palletizing robot will re-palletize the cases on new pallets for storage in the AS/RS.

(1) Cases of received raw and packaging materials are removed from the pallet. (2) The cases are moved through an air shower removing any dirt or dust. (3) Cases are re-palletized on new pallets and sent to the AS/RS. The clean area is kept at positive pressure.

System Examples

  • Robotic palletizer and depalletizer.

  • An AS/RS maintaining a clean environment using inside only pallets.

  • An AGV moves the raw and packaging materials from the AS/RS to the production line.

Work-in-Progress Storage and Automatic Resupply

Not only for food and pharmaceuticals, but for manufacturing in general, it can become necessary to temporarily store items mid-production due to factory uptime, the varying speeds of different production processes, or because the product requires rest before the next process. For these kinds of cases, by implementing an AS/RS, it becomes possible to temporarily store items and to JIT supply the production line. Compared to horizontal storage, using first-in/first-out (FIFO) storage to supply the production line helps prevent the use of items that fail inspection.

(1) Store work-in-progress product containers or pallets. (2) Products do not leave storage until they pass an inspection. (3) Based on the needs of the production line, goods are sent out using FIFO.

In addition, for certain products it is necessary to let them rest at controlled temperatures and humidity. For example, fermenting yogurt or aging chocolate. By using an AS/RS for these processes, it becomes possible to automatically have individual containers or pallets rest at a certain temperature for predetermined amounts of time. Due to it being unnecessary for personnel or forklifts to enter and exit the area, it is much easier to maintain the necessary storage environment. In addition to food processing, this system can be used in a wide variety of fields such as to maintain freshness of produce, preserve seafood, or in the production of reusable batteries.

(1) Containers of yogurt or packages of chocolate are loaded on a pallet and stored. (2) Stored items are fermented or aged at a controlled temperature and humidity. (3) After the set amount of time has passed, items are automatically removed from storage.

Automation of Product Shipping Preparation

Products that are finished and boxed are loaded onto an empty pallet which is then shrink-wrapped and stored. When an order arrives, the pallet is removed and products are loaded into trucks. If done manually, these processes demand a large amount of manpower.

With a combination of empty pallet delivering machines, robotic palletizers, automatic labelers, AS/RSs, AGVs, and other material handling systems, Daifuku provides a comprehensive automation solution for preparing products for delivery. At this stage as well, products can be blocked from shipping until they pass an inspection.

  • 1. The pallet dispensing machine dispenses empty pallets one at a time onto a conveyer.

  • 2. The palletizing robot stacks products onto the empty pallets.

  • 3. The pallet stretch wrapping machine wraps the pallets.

  • 4. Wrapped pallets are stored in an AS/RS.

  • 5. STVs bring the pallets to the truck lanes. For cases where one truck will make multiple deliveries, the system can be set to send products in reverse delivery order.

Solutions That Suit the Production Environment

At the production sites of food and pharmaceuticals, it is common to need to maintain certain storage conditions such as temperature, humidity, or cleanliness. Daifuku systems can support various environmental variables such as high humidity, high temperature, low temperature, cleanliness in line with ISO class 6-8 (Old federal U.S. standard class 1,000-100,000).

Maintaining a Clean Production Environment

Daifuku systems can provide various measures to match the level of cleanliness required.

  • Dust emission control: Stainless materials are used for racks that repeatedly come into contact with cases, totes, and other items.

  • Dust emission control: Dust emission from trollies is prevented by supplying electricity wirelessly.

  • Dust dispersion prevention: Covers are installed over the crane traveling rail, electric supply rail, and travelling guide rail.

  • Dust pile-up prevention: Racks have a closed section truss that prevents dust pile-up and makes cleaning easier.

  • Cleaning: Washable racks and conveyers with stainless materials, waterproofing, and oilless chains.

  • Cross-contamination prevention: Creating negative pressure and positive pressure areas or by using conveyers to send containers through a pass box when they move in and out of storage.

Other Specialty Solutions

  • Cold storage solutions: Stacker cranes, conveyers, and AGVs that can operate at up to -30°C.

  • 食

    Hot storage solutions: Automated yogurt fermentation with cranes and conveyers that operate at 40-45°C.
