The task was to solve the problem of transporting wrapped rectangular bales measuring 600x400x1200 mm or round ones measuring 600×1200 mm, with a weight of approx. 25 kg, from the production hall to two warehouses located in separate buildings. The system was based on belt conveyors; however, due to the shape of the transported material (cylindrical bales) and the route configuration, various design solutions were applied. Straight sections of the route consist of trough-shaped belts, while turns were made in the form of belt curves. “On the way” to Warehouse No. 2, it was necessary to direct a batch of loads to Warehouse No. 1 – according to the established program. For this purpose, a transfer unit was designed and manufactured in the form of a tilting belt conveyor section. This conveyor, when in a horizontal position, transfers loads straight ahead, and when tilted downwards, it allows the load to descend onto a belt curve, which directs the bale to the side, towards Warehouse No. 1. The adjustment of the tilting conveyor is performed by a pneumatic actuator controlled by an automation system.
Internal transport of mineral wool

It often happens that existing facilities are used in the investment process, where modern and efficient technological equipment is installed. However, a problem arises regarding the transport of the produced goods to the warehouse and then dispatching them efficiently to the customer.
Wandalex-ZUT – Zgierz encountered such an issue while implementing a project for the transport of mineral wool bales at PFLEIDERER Polska Sp. z o. o. in Dąbrowa Górnicza.
The trestles connecting the production hall with the warehouses could not interfere with transport routes around the buildings, so they were placed at a height of approx. 5 m. Consequently, a problem arose regarding how to lower the loads from this height to the “0” level without damaging them, and above all, ensuring full safety for the people receiving these loads. For this purpose, inclined double-belt conveyors were used, stacked one above the other, with identical belt speeds. Thanks to this, the descent of the load is controlled and safe for the operators.
An interesting solution is the unloading-loading conveyor in Warehouse No. 2. This conveyor consists of two belt conveyors placed one above the other. The upper conveyor is used for unloading bales into boxes located on both sides of the transport line.
