MANUMEC–140 (120) MANUAL HANDLING AND PACKING SYSTEM

Products are stacked up using manual handling lifter and then taken to the curing storage by a forklift or crane. After setting the products are transferred with a forklift to the manual packing lifter where they are packed on pallets. Production pallets are taken back to the production machine.


MANUMEC – 140 ELECTRO

MANUMEC – 140 ELEKTRO is a technologically advanced production line for concrete blocks and landscaping products. The product line uses vibration press technology. Concrete is pressed into moulds giving the products their accurate shapes and dimension. Each different product has its own mould, which can be changed to the product machine. Mecmetal Ltd. also manufactures moulds. (link to moulds)

PRODUCT HANDLING AND PACKING

Concrete product handling and packing is done in a semiautomatic production line. Production pallets and the products on them are transferred with chain conveyors between different phases of the process. There is a product brushing device on the conveyor coming out of the production machine. It cleans off loose concrete and small stones from products’ upper surface ensuring that product surfaces will be undamaged when they are stacked.

At the stacking position production pallets with products are stacked to 6 - 10 layers using a handling lifter (manual). The chain conveyor coming out of the production machine works as a buffer stock giving flexibility to product stacking. Stacked products are transferred to a curing storage with a forklift. Additional heating is not usually needed for the curing. Normal room temperature and humidity are enough. In fact, the curing reaction is exothermic producing heat by itself. The production cycle is preprogrammed so that products stay in the curing storage for about 24 hours.

After curing, the products are transferred to an un-stacking station where the products are un-stacked using a handling lifter. The products are put on a packing line chain conveyor, which also works as a buffer stock for the products.

The chain conveyor takes the production pallets and the products to the packing station. The products are lifted off the production pallets using a four sided gripper (manual) and put on shipping pallets that lie on the out-feed conveyor. The stack of ready products is wrapped up using metal bands or plastic film. The package moves along a roller track out of the production area.

Empty production pallets move on the chain conveyor from the packing station to the pallet turner. Empty pallets are cleaned by a brushing device and then they are moved back to the production machine for another production cycle. The is always a fixed number of pallets in the production cycle. The duration of each phase in the process is set in a way that process time of the handling line matches the production speed of the production machine. To ensure proper operation, there is a limit switch in the packing line that oversees that empty pallets are returned into the production. If an interruption occurs and there are not enough empty pallets for the production machine, it stops automatically.
