Are you looking to add a vibratory table to the manufacturing and/or shipping processes of your facility? If yes, great! We’d be glad to help put our experience to work and point you in the right direction. There are a few things to review during the buying process and each of these forks in the road can have an impact on overall cost of the equipment.
For starters, what can vibratory tables do? We commonly see the following reasons to include a table:
- Flatten the mound build up or pile of material made from the filling station discharging into center of the Gaylord, tote, box or similar type packaging container
- Compact and stabilize bulk bags, FIBCs or super sacks for easier stacking and handling prior to storage or shipment
- Fully or semi automate packaging lines by integrating with rollers sections (CDLR and gravity) or belt conveyors
- Fill, weigh and compact material
- Remove air bubbles in molds and casted products for improved structural and surface finish
- Lower labor hours and costs for packaging and processing lines
Next, let’s look at some items to consider when costing the project before ordering the capital equipment. There are different aspects of the vibrator table designs that account for various portions of the purchase price:
Where am I installing this vibratory table in my process?
What kind of surface does my application require?
Flat decks (FA Models) are designed with a contact surface that is a flat plate of steel with air vibrators or electric vibratory motors installed underneath. For bag fill station or other container compaction applications which require a low profile design, a flat deck fit with outboard vibrators makes a great space saver option. You can see this design featured above for our example of the flat deck series.
Grid tops (GT Models) are designed with vertical grids that raise above and lower below the roller section (CDLR or gravity) the table is integrating with during installation in an automated or semi-automated packaging and filling processes.
Belt tables (BT Models) are designed with a flat deck vibratory table model that is built underneath the belt conveyor to allow for vibrating and conveying at the same time. The BT Model is ideal for applications that requires gentle vibration to remove air pockets in molds or flatten bags prior to palletizing. Think of your favorite pet food for your pet, we will bet that their food has been vibrated before it reached the shelves of your local pet store using a piece of equipment like the BT Model.
What type of surface material does my application require for the vibratory table construction?
Stainless steel costs can add up quickly, material alone can be two to three times more expensive than mild steel. Our cost-efficient solution, we can make the product contact areas stainless steel while all other components mild steel or use mild steel and finish the exterior with corrosion resistant coatings.
What kind of power supply does my application call for?
Pneumatic power typically uses our VMSAC Air Cushion Piston Vibrators which are manufactured here at Cleveland Vibrator. This is an economical option for applications that take place in hazardous environments. However, this power supply is limited to lighter design loads, usually around 2,000 lbs. max load capacity.
Electric power uses RE Rotary Electric Vibrators for tougher applications involving much larger max load capacities. The Rotary Electric Vibrators can handle up to 20,000 lbs. or more giving the user the independent control to adjust the the force and frequency that their application requires. This does require a higher price commitment into the investment of the piece of the equipment.
- Coil springs are most versatile and economical but can be noisy. These can be used on all frequencies.
- Marsh mellow mounts are great isolators but not effective for equipment with high frequency vibrators (1800 RPM/VPM or lower is suggested).
- Air bag isolators are, from our experience, the best isolation package available. However, this option is also the most expensive and air needs to be available to properly operate. But, these are needed for the grid top designs to allow for the raising and lowering of the vertical grids to get above or go below the top of roller height. As an added safety feature, these can also be programmed into the vibratory controls package to prevent vibration from turning on when the air bags are not inflated.
Does my application require load cell or weighing capabilities? When needed, load cells can be included in a vibratory table design to help with semi-automatic or fully-automated packaging and processing lines. These load cells are isolated from the vibration and installed under the supporting legs of the flat deck, low profile flat deck, grid deck or low profile grid deck table designs. When integrating the load cells into the vibratory table, it is possible for us to provide a controls package that can help communicate between the load cell modules, vibratory motors, fill device and/or CDLR roller sections.
Lastly, when compiling the list of “must haves” with the vibratory table equipment, these items listed all have an impact on performance of the equipment itself along with purchase price and required maintenance during operation. For an example, let’s take a look at some budget numbers of two units for a similar application – 48” x 48” flat deck table designed to compact and stabilize a 1000 lb bulk bag underneath a filling station:
Air powered unit with the following options:
- Low profile deck design
- Mild steel construction
- Air powered vibrators with solenoid valve controls package
- Coil spring isolators
- No load cells
Total Budget Price – Between $5,000 and $8,000
Electric powered unit with the following options:
- Low profile deck design
- Mild steel construction
- Vibratory motor controls package for on/off, frequency adjustment and quick stop (dynamic brake)
- Marsh mellow isolators
- Load cells controls package to integrate with the fill station (fast and dribble fill settings), load cell modules and vibratory motors
Total Budget Price Estimates – Between $20,000 and $25,000
The more automated the equipment, to higher the price tag. Unfortunately, that comes with the territory. However, with the increase in automation comes (usually) a decrease in labor hours to get the job done. Something to consider when looking at this type of equipment.
Keep in mind, these are rough numbers and can vary when specifically sizing the project for your needs. But, hopefully this helps give some idea of what to expect and what to consider when exploring the idea of adding a vibratory table to the production or packaging line of your facility.
