Detailed Description
The existing tray type steel coil conveying line is distributed in an up-down mode, an upper layer heavy-load roller bed conveys a steel coil and a trolley, a lower layer no-load roller bed only conveys a returned empty tray trolley, and the conveying line comprises the following basic equipment:
the steel coil lifting trolley comprises: the steel coil lifting trolley has 3 main working positions, namely a middle waiting position, a coil receiving position and a coil unloading position. The steel coil lifting trolley has the function of conveying steel coils from the bundling station to the conveying chain transverse moving roller bed in a circulating action of 'retreating- > lifting- > advancing- > descending- > retreating'. The main trigger condition of the automatic execution cycle action of the steel coil lifting trolley is that a cold metal detector arranged at a bundling station detects an occupying signal.
And (3) traversing the roller way: the transverse roller way consists of 2 groups of roller ways capable of moving in parallel and is divided into a coiler side roller way and a conveying line side roller way. And the side of the coiling machine is used for receiving the steel coil unloaded by the steel coil lifting trolley, and after the steel coil is transversely moved, the steel coil is conveyed to the side of the conveying line from the side of the coiling machine. And the side of the conveying line is only used for conveying general pallet trucks. The main trigger condition of the automatic execution cycle action of the transverse moving roller way is that a cold metal detector arranged at the station detects an occupancy signal. Each roller way is provided with 3 limit switches for detecting the position of the pallet trolley.
Lifting a roller way: the lifting roller way consists of 1 or 2 groups of lifting moving roller ways and is divided into a heavy-load roller way and an idle roller way. The heavy-load roller way can convey the steel coil to the ground from a low position to a high position, and the no-load roller way is used for conveying the tray trolley after coil unloading back for recycling. And 3 limit switches are arranged on the roller way and used for detecting the position of the tray trolley.

The basic transportation process of the tray type steel coil transportation line is as follows:
and after the hot rolling coiler finishes a coiling process, the steel coil is moved out of the coiler through a coil unloading vehicle and placed on a bracket of a steel coil bundling station, and bundling operation is performed according to needs. A cold metal detector is arranged at the bundling station to judge whether a steel coil occupies space.
And after bundling is finished, the steel coil is conveyed to the tray trolley of the transverse roller bed from the bundling station by the steel coil lifting trolley. The transverse roller way is used for horizontally moving the tray trolley carrying the steel coil from the side of the coiling machine to the side of the conveying line and then forwards conveying the tray trolley carrying the steel coil through a common heavy-load roller way.
When the weighing station is reached, the tray trolley stops moving forward, and automatic weighing operation is carried out; after weighing is completed, the tray trolley continues to advance.
When the pallet trolley reaches the rotary roller way, the rotation direction is issued by the secondary control system, and the pallet trolley continues to advance to each section.
When the tray trolley arrives at the lifting roller way, the steel coil is conveyed from the lower position to the higher position; then the coil is conveyed to each coil stripping position through a common heavy-load roller way. And cold metal detectors are arranged at the coil unloading positions, and when the coil occupying signals on the trays of the coil unloading positions cannot be detected, the lifting roller tables of the coil unloading positions drop the empty trays to the low positions and the empty trays are gradually transported back by the no-load roller tables.
