25-storey press

Composition of press with pressing mechanization and pre-press with mechanization of loading and unloading operations

1. Transporter of loading and unloading - for receiving of a stack of sheets and simultaneous pre-press unloading and loading.

2.Pre-press (force – 5000kN, individual pump hydraulic drive)

3.Output roller – for receiving a stack of pre-pressed sheets and their supply to the lifting table.

 

 

 

4.Lifting table with roller – for lifting of sheets stack to the level of supply of top sheet to shelving loading mechanism.

5. Shelving loading mechanism – for storey-loading of shelving.

6.Loading shelving – for horizontal transportation. Located near the press.

7. Loader – for partial ejection of pressed plywood from the press after its opening and subsequent loading of press.

8. 25-storey hydraulic press (force - 6300 kN, individual pump hydraulic drive).

9. Unloading shelving – for vertical transportation. Located near the press.

10. Discharge device – for storey discharging of unloading shelving.

11. Accumulator – for forming a plywood stack.

12. Receiving conveyor – for receiving a stack of plywood from accumulator and its subsequent transportation by means of workshop mechanization.

Composition of section of sheets assembly

1. Receiving conveyor (2 pcs) – for placing of alternate stack of veneer near glutinous roll machine.

2.Under stack lifting table (2 pcs) – for veneer stack lifting on the level of supply to glutinous roll machine.

3.Glutinous roll machine (2 pcs) – 4-roll with dosing rolls and glue circulation system.

4.Circular transporter (2 pcs) – for veneer feed from glutinous rolls to sheet assembling table.

5. Lifting table with roller (2 pcs) – lifting hydraulic table, on which manual assembly of sheets is performed with subsequent transfer of the stack on the rotary table.

6.Rotary table – for receiving a stack of sheets from two assembly tables and subsequently feeding on the pre-press conveyor.

7. Under stack conveyor (2 pcs) – for veneer supply to sheets assembly table. Capacity – 2 stacks.

8. Under stack tables (5 pcs) – for veneer stack and transport pallets for pre-pressing of stack of sheets.
