EQUIPMENT FOR PACKING FASTENERS IN A PACKING CONTAINER

The process of packing and packaging machine-building fasteners on the line includes the following main technological operations:

1. Unloading a batch of fasteners from a factory container (ship shape bin) using a crane into a vibrating hopper of the packaging line;
2. Gradual transportation of fasteners from the vibrating hopper to the filling unit using a magnetic lifting conveyor. From the vibrating hopper, the fasteners are gradually poured under the influence of vibration and gravity onto the primary feed device. Under the influence of vibration, a uniform supply of the original product to subsequent units is ensured and the absence of clumping of lengthy fasteners.
3. Sequential operations of rough and precise packing of fasteners into batches with a predetermined weight. At the exit from the primary feeder, the fasteners are gravity fed into the secondary and tertiary feeders. The packing error of the weighing unit is not more than ±1% of the specified weight.
4. Delivery of the formed batch of fasteners to the packing vibrating chute. Formation of empty boxes is carried out by service personnel. The formed boxes are placed on a driven feed conveyor, from where, by means of a conveyor belt, a sensor system and a movable table, they are positioned in the position of loading the fasteners exactly under the electromagnet tray. When the gates of the storage hopper of the distribution unit are closed and a new batch of fasteners is set, the movable tray goes down, entering the corrugated cardboard container. Thus, when the fasteners are poured from the vibrating tray into the chute, the complete unloading of the collected batch into the container is ensured without spilling products outside the box. At this moment, the movable table moves to its original position to receive the next empty box. After the end of the cycle, the chute rises vertically upward, and the filled carton with oriented products is pushed by the movable table onto the discharge conveyor.
5. Gradual pouring of the formed batch of fasteners into the corrugated container with simultaneous electromagnetic orientation. When packing fasteners into corrugated cardboard containers, the assembled batch of products is gradually poured into the unit for electromagnetic orientation of fasteners. Such a feed allows avoiding damage to the bottom of the corrugated cardboard box when unloading a batch of large weight and creates optimal conditions for orienting the fasteners when passing through the electromagnet.
6. Transportation of the filled box to a vibration station for vibrating fasteners in a container. The driven discharge conveyor moves the filled carton of product onto the vibrating table. If the weight of the finished box does not match the specified parameters, the box is pushed onto a non-driven roller conveyor, where the service personnel can adjust the weight of the product in the box and then put the box back on the conveyor. On a vibrating table, vibro-laying (shaking) of products in a box is performed. The vibrating table is located at a slight angle, due to which the shaking box under its own weight moves to the accumulating non-drive roller table. Next, the service personnel manually close the box flaps and tap the seams with adhesive tape as the box passes through the conveyor.
7. The box arrives at the palletizing station. The formed box is transferred to an automatic pallet forming station (palletizer). Pallets are automatically fed to the station from the store for 5-6 pallets. The first operation is to turn the box to the required position on the rotary roller table. Further, a separate row is formed from the correctly rotated boxes, which is then shifted onto a pallet using a hydraulic pusher. When the next layer is collected, the pallet moves down to the height of the box, so that the pusher moves the next row of boxes to the previous layer. Cardboard spacers between layers, if necessary, are laid manually by service personnel. The finished pallet is transported by a forklift to an automatic pallet stretching machine.
8. Tightening of the formed pallet with stretch film. The pallet is installed on a rotating drive platform, the operator fixes the edge of the film on the pallet and starts the machine from the operator's console. The formed pallet is pulled by the film with a predetermined tension, overlapping height and the number of layers of the film. The packed pallet is transported by forklift to the finished product warehouse.
