2. INDUSTRIAL ALLOCATION SCHEME


There is alternative industrial allocation scheme in a case of equipment set with 2 glueing machines:

Possible variants for equipment set #2:

• Steel forming machine without set of roof steel forming rolls (steel forming rolls - 72 items, spacing collars (separators) -28 items). Box dimentions 600mm х 600mm х 500mm, 250 kg.
• Additional set of profil knives for manual guillotine (installed after steel forming machine).

3. DESCRIPTION OF EQUIPMENT SET #3

De-coilling barrel, steel forming machine, guillotine, roll-table	Glueing device (with roll-table)	Thermo press roller-type, input roll-table

De-coiling barrel with actuator and speed control from central control unit. Maximal weight of steel - 5t (N = 2,2kW). Equipt with detector for definition of level of steel film sag for de-coiling speed control. Possible variants: 5, 7, 8 and 10t (the price will differ).

Guiding device with device of protective film covering and across cutting for the right orientation of steel (vertical and horizontal orientation before steel forming machine. It is equiped with input rolls, guid plankes, cutting device for across cutting of steel in a case of readjusting steel forming machine for another type of side-lock (change of steel forming rolls). Option: guiding device equiped with length cutting device.

Stell forming machine - designed for steel forming (preparaiton of sandwich panel steel cover) - forming of main profil and side-locks. Steel forming machine coud be readjusted for another type of steel forming (wall and roof sandwich panels). Steel forming machine has its own actuator (N=4.0 kW). It has a central control unit wich microprocessor. The control unit controls the stell forming machine and de-coiling barrel. Steel forming machine length = 2.4m. The machine has 7 mill for forming of side-locks (mill length - 300mm, stell forming rolls diameter - 150mm, total number of rolls - 78items, number of spacing collars (separators) - 22items). All rolls are driven with actuator by tooth gear drive. Readjustment for another type of side-locks takes nearly 15 minutes. Storage stand for set of changeable rolls is included in the price of stell forming machine. Un-coiling device is installed for the steel waste removing.

Manual guillotine with profile knives - designed for cutting formed steel, installed after steel forming machine. The length of formed steel is limited only by the lingth of receiving table (it is variable and non-discrete). Accuracy of cutting - ±1mm. Guillotine has 2 sets of changeable knives for cutting wall and roof sandwich panel covers.

Glueing device - delivered with modular-type roll-table with possibility of length increasing (1 module width is 1m). Roll-table doesn’t have and actuator, steel transferring – manual. The construction could be easily assembly or disassembly for transportation. Glueing is executed by pressing-out glue through nozzles. A glueing bogie with actuator goes along the steel (speed is variable). Glue is delivered with pump (final pressure is controlled and is constant). Provision of washing of system with solvent after finish of work.

Receiving roll-table is modular type with possibility of length increasing (1 module width is 1m). Roll-table doesn’t have and actuator, steel transferring – manual. The construction could be easily assembly or disassembly for transportation. 1 roll-table is installed after steel forming machine, 1 – after thermo-press.

Universal table for manual cutting out of grooves in polystyrene foam and mineral wool (for inserting into roof panels) is designed for cutting of technological grooves and for cutting of insert-element trapezium-shape of foam plastic for inserting to the waves of roof sandwich panles.

Additional Equipment

Stock shelves (mezzanine) is designed for intermediate storing of sandwich panel covers between operations of steel forming and pressing.

Sandwich panels packing platform is designed for special hard packing of sandwich panels packets in a case of transportation to 1000km or more.

Mini-laboratory (mini presses) is designed for definitions of modes and conditions of pressing and glue parameters. With each new batch of glue it is extremely advised to define the required pressure, time of pressing and other parameters using this mini-laboratory.

4. BRIEF DESCRIPTION OF TECHNOLOGICAL PROCESS

Preliminary steel forming operation:

1. Sandwich panel cover #1 forming operation – automatic, 40% of the shift
2. Transferring of cover #1 to stock shelves (mezzanine) by device for transferring of sandwich panels covers (telpher)
3. Go-to operation #1 till the required number of covers on stock shelves
4. Operation #1 for type-2 covers (in a case of roof panels production) – 5% of the shift

General operations:

1. Steel forming operation of cover #2 (automatically)
2. Transferring of cover #1 from stock shelves (mezzanine) by device for transferring of sandwich panels covers (telpher) to glueing machine
3. Glueing of cover #1 (automatically)
4. Transferring of cover #1 to stock shelves (mezzanine) by device for transferring of sandwich panels covers (telpher)
5. Transferring of cover #2 to glueing machine by device for transferring of sandwich panels covers (telpher) from receiving table of steel forming machine
6. Glueing of cover #2 (automatically)
7. Placing of mineral wool (foam plastic) on glued cover #2 (manual)
8. Transferring of glued cover #1 to stock shelves (mezzanine) by device for transferring of sandwich panels covers (telpher)
9. Input of assembled sandwich panel to thermo press (automatically)
10. Starting of the next cycle from operation #1
11. Pressing – passing of sandwich panel through thermo press (automatically)
12. Output of finished sandwich panel from thermo press (automatically)

The bottle-neck is pressing operation (6-meters long sandwich panel for 5 minutes).
Taking in account required time for execution of additional and preliminary operation, equipment set productivity is 50 sandwich panels (or 300 meters of panels) per shift (8 hours)

Annual productivity is 100’000sq.m. (single shift work) of 200’000sq.m. (double shift work)
