Big bag and sack discharge with forklift

‹‹ ››

Unloading of sacks and big bags on the same discharging point

Mild steel, stainless steel 304 and 316 manufacturing

Palamatic Process developed standard bulk bag unloader to meet the needs of powder handling industries charging their process with big bags and sacks (25/50 kg) on the same discharging point.

Two standard sizes available (short delivery time) ; passage width for big bags: 1250 mm & 1500mm.

This fibc emptying station allows deconditioning super sacks and sacks ergonomically using a forklift and a specific handling cross. The dust emissions are minimized by the introduction of effective containment devices (dustproof rubber seal, containment tube, nozzle for connection to dust collector). The product flow is optimized by the introduction of a vibrating plate (vibration motor) or a pneumatic massage system option.

The design office Palamatic Process is able to offer very specific solutions.

Reference codes: DP 125C & DP 150C

Specifications

Fibc discharging unit with forklift loading: reference codes: DP125C / DP150C

Equipment integrated on standard versions (excluding options) :

  • Structure supported frame with tracking railway: allows the setting up of the big bags via the forklift (adjustable height of the structure to fit different heights of big bags and locators to securise the setting up of the big bags)
  • Main tray: maintains the big bag when emptying and secures handling operations
  • Rubber seal on main tray: to optimize containment by capping the bottom of the big bag
  • Vibrating motor: to ensure the vibration of the main tray to help the extraction of the powder
  • Unlacing cabinet with dust-proof door : to provide a secure and ergonomic access to the spout of the super sack
  • Anti-overflow tube: channels the flow of product into the unlacing box and facilitates the handling of the operator
  • Protection screen: ensures feeding of powder without foreign body (mesh size 50 x 50)

The manufacturing of the units is possible in mild steel, galvanized steel, stainless steel 304L or 316L. The parts in contact with the product and the structure can be manufactured with different materials.

Operating mode

Big bag loading:

Chargement chariot

The setting up of big bags, made by the driver of the forklift, is securised by the specific handling cross and the use of locators implanted on the structure. When installing the big bag in on emptying station, the handling cross indexes in the locators locators providing safety and ease of positioning.

To meet the different dimensions of big bags, the station is adjustable in height via a telescopic sleeves system with locking rods.

This robust technology can empty big bags over 2200mm height.

Ergonomic access to the unlacing cabinet thanks to the adapted height of the box. The dustproof door and the anti-overflow tube ensure total containment during the phases of opening and emptying of the big bags.

Options

tension system for big bags

Handling cross with tension system

To allow optimum unloading of the big bag, an autonomous tension system of the sides of the super sack is offered as an option. This system avoids the retention pockets and ensures optimum emptying without loss of product and without operator intervention.

security baffle

Security baffle

Security baffle ensuring correct attachment of the straps of the big bag (possibility of a different design).

glove box on fibc unloading unit

Glove box

Handling of toxic chemicals and contaminants.

The gloves are installed on the door of the unlacing box and fitted on round PVC gloves. Spring clips ensure containment and closure. A neon implanted outside through a plexiglass facilitates the operations of opening the big bag.
The glove box allows the user to manipulate the big bag without being in contact with different products that may be toxic. Indeed, the glove box will allow the user to undo the knot of the big bag to allow its discharge. A screen is added in the cabinet to secure the process.

Gloves material manufacturing  is adapted to the requirements of your products.

dust proof telescopic tube

Dust proof telescopic tube

It allows a dust proof connection of the big bag and tension on the cuff of the super sack.

The double envelope telescopic tube is connected to a flat ring through spring clips. The pneumatic cylinder allows the operator to adjust the connection height to fit different types of big bags. The dust-proof connection is made with a sealing ring and an inflatables eal product to avoid the product retentions.

de dusting ring

Dedusting-ring

It enables to create a uniform air flow in the periphery of the tray to optimize the dust extraction when emptying the big bag. The ring is mounted on the receiver plate. It consists of a split tube and a pipe for connection to the de-dusting unit. It is manually operated to adjust or close off the suction flow.

v shape spike to burst the big bag

"V" shaped spike to burst the big bag

This spike allows the opening of the big bag without any direct action from the operator. It is especially utilized when using "full bleed" big bags ("V" shaped spike).

Once the big bag is placed on the unloading station, the operator takes the big bag down thanks to a hoist and put it down on the main tray. The force applied by the weight of the product on the blades allows a direct cut of the bottom of the big bag.

For the big bags with a spout, the spike is shaped like a “U”  and allows the opening of the big bag at the level of its spout.

massage flow system with continuous actuator

Fibc massage system

To improve the flow of the product : Pneumatic actuators implanted on the lower part of the structure break the domes and eliminate caking (2, 4 or 6 actuators depending on the type of powder).

Possible option : vibrating tray : tray implanted on silent-blocks to optimize the flow of the product. The massage solution may be offered as independent equipment to prepare the big bags before unloading.

control valve on big bag unloading system

Control valve

To stop or simply control the product flow.

The PALAMATIC control valve enables the operator to stop very flowing products or to control the flow : a pneumatic valve strangles the spout of the big bag.
This valve is actuated by pneumatic cylinders and allows the operator to stop or regulate the flow of the powders at any time by a switch located on the control panel.

commercial dosing and weighing

Commercial dosing and weighing

Weight of the big bag unloading unit for an accurate feeding of the downstream process.
The complete system for unloading the super sacks is set on 4 load cells. To avoid any risk of tipping of the structure, the wheelbase is increased.

lump breaker on fibc dumping unit

Lump breaker

 

Our lump breakers are the ideal solution for the crushing of materials that tend to form lumps.
The device permits to break the lumps that develop during the process of production or transportation of friable materials in powder or grain.

fibc compactor

Fibc compactor

The Palamatic big bag compactor reduces the volume of waste and keep a healthy atmosphere without dust. It can be fitted on one side or the other of the structure.

See our fibc compactor.
