Information:

The very accurate and easy to operate Model S-5 semi-automatic scale has automatic tare, automatic feed and speed controls for both bulk and dribble feed rates, and automatic set points. The product flow from the hopper to the feed pan can also be controlled by an adjustable slide gate.

Example: To run a relatively free-flowing product into a 10lb. package, the product is loaded into the hopper, and the target weight is set at 10lb. The package is placed on top of the scale, and the table is adjusted (up/down) so that the funnel is inside the bag in order to keep the bag “standing” when empty. After starting the first fill cycle with the foot pedal, the controller will automatically switch into “learn mode” for the first cycle. During this time the controller tests the flow characteristics of the product and decides the best speeds and durations for bulk and dribble. The controller will automatically change the vibratory feed from bulk to dribble and stop the scale at 10lb. The bag is removed and sealed. Each successive container is now filled by placing it under the funnel and depressing the foot pedal.

All product contact surfaces are stainless steel and easily disassembled: two screw knobs hold the funnel, two screw knobs hold the vibratory feed, four nuts hold the hopper. If needed, the scale and control panel can be removed from the table, and the table can be removed from the frame.

Information:

The model S-7 two lane net weigher share many of the same basic characteristics of the S-4. A very accurate and easy to use controllerI allows for three different modes of operation. In simultaneous dump the machine fills both weigh hoppers at the same time, allowing for twice as much product flow as our S-4. In individual dump the machine dumps whichever weigh hopper is at weight. This gives twice the speed of our S-4 machine. Finally the model S-7 can mix products. The controller can be set to weigh two completely different products at different weights to easily mix products into a container.

Application Guide for Net Weight Filling 

Step 1 - Determine the volume of your fill

The first step in determining which of our net weight fillers is best for you application is to determine the weights you wish to fill, the containers you wish to fill into, and the volume of the fill. All products have different densities so this is very important!  5lbs of rice is a different density than flour or raisens. You will need to determine that in cubic inches (cu.in.).

(These calculations are not needed for the S-5 Bulk Weigh Filler).

For rectangular products multiply Length x Width x Height in inches.

Example 1: Filling into a box 4" x 2" x 8.5" = 68 cubic inches

Example 2: For cylindrical containers the calculation is:

3.14 x radius squared (radius is 1/2 diameter) x Height

Example: A can 8" diameter, with 10" height =

3.14 x 4 x 4 x 10= 502.4 cubic inches

We now know the size that the weigh bucket needs to be.

Example 1 above will easily fit the standard weigh scale for the S-4 which is 250 cu.in.

Example 2 will require the upgrade to the 650 cu.in. weigh hopper.

So if you are only filling productus under 250 cu.in. the standard will be fine. But if one or more products require over 250 cu.in., so long as none exceeds 650 cu. in., then the upgrade will be required.

Step 2 - Determine Production Requirements

Typically most products will run about 10 cycles or more per minute per scale (S-5 about half of that) with good accuracy. But there is no hard and fast rule for speeds as products have size, cost, and flow differences, and your accuracy requirements may be more stringent than are "typical". The S-7 has two scales so speed can be doubled over that of the S-4!

When we are discussing speeds there are other factors that "weigh in" that are beyond the weighing system's mechanical aspects.  For instance visualize a quart sized bottle with a 28 mm neck opening running a no quite so free flowing a product such as flour. Even though the weigh scale may be able to mearsure out the correct weight into the scale bucket at 10 cycles per minute, the restriction of flow due to the small neck opening can be so great that the flour would flow into the bottle through the funnels after dump so slowly that speed may be very restricted due to that factor alone. But switching to a wide mouth opening to the bottle would allow for much faster filling.

Still most free flowing products will run easily at about 10 cycles or more per minute or 600-800 cycles per hour, which is about the maximum rate that can be handled by an operator in semi-automatic mode. For extreme accuracy the rates could easily be half of the rate, in which case going with the two head S-7 weigh filler might be a good option, even in semi-automatic mode so as to get the rate back up to 600-800 cycles per hour.

For automated systems that can produce up to 1600 cycles per hour we highly recommend the S-7 two scale net weight filler.

Step 3 Determine the Accuracy Requirement

All of our scales can weigh down to 1 gram accuracy.  But just because the scales are very accurate does not mean that your fill will be that accurate. For instance envision a 2 lb bag of doggie bones where each bone weighs 1 oz. Running on an S-4 on the fast feed can load the bucket pretty quickly and let's say the fast feed cuts off at 1lb 12 oz before going into dribble feed mode. Depending on the height of the flow gate on the main hopper there may be as many as 5 to 8 bones that are nearly ready to drop into the scale. In this scenario we may end up with a fill of 2 pounds 4 oz. One way we can mitigate that is to add a dribble feed gate that allows only a narrow band of product to flow in, more or less dropping in one at a time until weight is made. Even so in a state where we have 1.99 pounds, if only one more piece drops in we will be overweight by almost 1 ounce. In other words, no scale system can fill more accurately than the heaviest particle or part in the batch.

But for ultimate accuracy the S-6 cascading style net weight filler is the answer for parts counting or the doggie bone above, or odd sized - hard to feed products like potato chips.

This is because there are two vibrating trays, the first set at the same speed as above in the doggie bone discussion, but the second tray is set to a faster speed to allow product to spread out to a thinner more manageable level, while allowing the same overall feed rate. So now when the scale system drops into dribble mode, there may only be one or two bones ready to drop into the scale.  Add in the dribble feed gate and you have the most accuracy available.
