CHAPTER 1

RECEIPT AND

ASSEMBLY


The CBE 900 Impeller Packer consists of the packer assembly and various items as ordered.

1. Receipt and Inspection After uncrating the packer, a check should be made to see that all items ordered have been received and that all equipment is in good condition. Any damage incurred in shipment should be reported immediately to the delivering carrier and a claim for the damage should be filed. Also notify Choice Bagging Equipment, Ltd. so that replacement or repair may be initiated. The CBE 900 Impeller Packer is shipped with locking bolts installed to secure and protect the bag post and weighing assembly during shipment.

2. Assembly Procedures 1. Mark the centerlines of the packer, reference the General Arrangement drawing. 2. Set the packer into place. It may be desirable to defer final anchoring to the floor until after testing. Place

the packer in the proper location, insuring the frame is level. Check the clearance and fit to the feed hopper and associated piping prior to securing it firmly to the floor.

3. Install rubber connection sleeve between bin and

hopper to isolate bin vibrations from packers. (Sleeve not provided with machine. Recommend 0.25” - 0.375” wall thickness. Sleeve can be purchased from CBE separately).

4. The weighing assembly is secured by a locking bolt

that protects the scale from any damage during shipment. Be sure to remove the locking bolt located underneath the top flexure plate before attempting to operate the machine. (Some models may contain 2 locking bolts).

5. If the equipment uses a load cell scale weighing unit, make certain that the load cell and parts suspended on it are free from side friction.

6. Adjust the fill tube on the bag post into alignment with the isolator tube and the chamber housing. This is

accomplished by loosening the fastening bolts that hold the bag post in position and adjusting the bag post either up or down into position.


CHAPTER 2

OPERATION


1. PRINCIPLE OF OPERATION The CBE 900 Impeller Packer is a semi-automatic gross weighing valve bag filler. It has a specially designed 4-blade powered by a vertical drive shaft. Product flows by gravity from the supply hopper into the product feed inlet at the top of the machine. When a fill cycle is initiated, the horizontal impeller creates a positive draw on the product moving it through the feeder and into the bag. The Model 900 is a gross weighing filler, meaning that it simultaneously fills and weighs product directly into the bag. To initiate a bag fill cycle, operator or automated bag applicator (sold separately) is required to put an empty bag on the filling spout activating the auto start with the empty bag in place. The bag is then filled and weighed automatically and when equipped with a powered bag chair (CBE Assembly # 106-300), it is discharged automatically when the target weight is reached. If for any reason it is desired to interrupt the filling operation in the middle of cycle, a STOP pushbutton is provided. This is the Red pushbutton facing the operator. Pushing this button stops the packer as a safety precaution also. An impeller feed assembly is the main feature of the CBE 900 Horizontal Impeller Packer. The impeller housing receives bulk product from a surge bin and supplies a steady stream into the bag utilizing a four blade impeller High-pressure air (80 PSIG), operates the solenoids and cylinders. On actuation of Start signal by the operator the bag clamp clamps the bag to the fill spout, a cutoff device opens to allow the air-solids mixture to be fed to the bag. The cutoff closes automatically when the material in the bag reaches a pre-determined weight. Bags are weighed during the filling operation on a unit consisting of bag support frame and filling tube mounted on the front of a scale beam. Filled bags are discharged automatically when the machine is equipped with an automatic discharge bag chair arrangement. All of the operation activity for each bag filling cycle takes place in a matter of seconds. This packing speed is important--not only to achieve high production rates, but also to achieve precise bag weight accuracy, the product must be delivered in a consistent, even flowing stream to the CBE 900 Horizontal Impeller Packer

2. SECUENCE OF OPERATION The CBE 900 has a TWO PHASE operational sequence for filling a bag. It should be noted, however, that a variety of optional functions and features are available for the CBE 900 and your machine may or may not be equipped with all of them. The sequences listed below, show the optional timed powered discharge and inflatable bag seal.

A. PHASE ONE Phase one is the condition in effect at the end of a filling cycle. After actuation of the Stop (or scale) signal the following sequences occur.

1. The flexible pinch tube cutoff closes, stopping the flow of material to the bag. 2. When the motor drive assembly stops and the impeller material feed assembly stops the flow

of material from the product surge bin above the machine to the bag. 3. The bag clamp releases and the bag is discharged from the machine. Since material gravity

flows into the machine it is continuously recharged.

Various optional features shown on the schematic op erate as follows: 1. The valve sealer deflates - this can be timed to ensure material stabilization in the bag. 2. The powered discharge bag chair tilts to discharge the filled bag at the end of the sealer

deflation and returns.


The speed of these features is controlled with special pneumatic controls. During Phase One, the operator also places an empty bag on the filling tube after discharge of the previous bag.

B. PHASE TWO Phase Two is the condition in effect during the filling cycle. After actuation of the start switch the following conditions occur:

1. The bag clamp secures the bag to the filling tube. 2. The bag sealer inflates inside the valve of the bag. 3. The drive assembly is activated by the motor controls spinning the impeller assembly and

starting product flow from the housing, through the pinch tube cutoff, and into the bag. 4. The material is weighed in the bag until the desired net weight is reached. 5. When the bag comes to weight, the "Stop" circuit energizes and the condition in Phase One is

in effect. If the packer is equipped with the optional automatic starting device, the start signal is obtained automatically when the bag is placed on the filling tube and contacts the starter lever.


CHAPTER 3

START-UP &

ADJUSMENTS


The CBE 900 is an automatic packer. The operator is required to put an empty bag on the filling spout activating the auto start with the empty bag in place. The bag is then filled and weighed automatically, and when equipped with powered bag chair, is discharged automatically upon weighment complete. If for any reason it is desired to interrupt the filling operation in the middle of a cycle, a Stop pushbutton is provided. This is the red pushbutton. It is recommended that the following adjustments be made to the packer before any material is delivered to the receiving hopper. Make sure all personnel are clear of machine. 1. PNEUMATIC CONTROL SYSTEM

1. Open manual valve for incoming high-pressure air. 2. Adjust pressure regulator to 80 PSIG (with power off). 3. Place an empty bag on the filling tube putting machine in filling mode.

NOTE: Components should now be in Phase Two operation.

4. Adjust the bag seal pressure to 3-7 PSIG (optional equipment). The bag seal should expand just enough to secure the valve of the bag. Further adjustment may be required during the next fill cycle.

NOTE: Excessive pressure may cause damage to the bag seal and tear the bag.

5. Press the Stop pushbutton to stop machine.

NOTE: Components should now be in Phase One operation.

2. SCALE BEAM SETUP

1. Place a weight equivalent to the desired bag weight on the Bag Chair. 2. Slide the scale weights (12 oz. or 8 oz.) on the Upper Pivot Beam until the wand just moves past the air receiver.

3. Remove weight. 4. Start packer.

5. Further Adjustment of the scale weight (12 oz. or 8 oz.) may be required until the desired weight is achieved. If the filled bag is underweight, adjust the weights further out on the Upper Scale Beam. If it is overweight, adjust the weights further in on the Upper Pivot Beam.

3. PNEUMATICS

1. Regulator- located on the back of the packer is a Filter, Regulator assembly. The plant air is introduced into this assembly through the filter and then to the regulator which is adjusted by turning the screw at the bottom of the regulator which is adjusted by turning the cap at the top of the regulator so that the pressure gauge registers a minimum of 80 pounds of pressure. 2. Flow Control Valve- The Flow Control Valve introduces a constant flow of air into the orifice of the housing. The primary purpose of this air is to fluidize the material as it enters the orifice thus preventing any plugging. This assembly is made up of a check valve ball, ball valve and pilot valve.


4. ADJUSTING THE BULK & DRIBBLE CUTOFF MECHANISM ( OPTIONAL; CBE Assembly # 103-300)

INSTRUCTIONS

1. Bulk solenoid gives signal to port #1. Cylinder retracts fully, material flow not restricted. Air exhausts through Ports #2 and #3.

2. First set point (Dribble) is reached. Bulk solenoid gives signal to port #3. Cylinder partially closes restricting material flow. Air exhaust through Ports #4 and #1.

3. Second set point (Final Cutoff) is reached. Signal goes to port #2 cutting off flow completely. Air exhaust

through Port #1.

4. To control dribble speed, material flow (more or less) adjust Knob #5 located on top of cylinder. Turn the knob counter clockwise (up) for less material flow, clockwise (down) for more material flow.

5. BAG CHAIR POSITIONNING Bag chair is raised and lowered manually to adjust to bag length. A series of holes in the bag post accepts a pin on the bottom of the chair assembly, resulting in a secure setting. Pasted Bags: Place a bag on the filling tube and smooth the body of the bag down. Unfold the

bottom of the bag to a Vertical position. Position the bag chair so that it touches the bag.

Sewn Bags: Place a bag on the filling tube and smooth the body of the bag down. For first setting, position the bottom of the bag chair 1" below the bottom of the bag.

Because of the wide variety of valve bags available, trial and error experimentation may be required to obtain the optimum bag chair adjustment. Correct adjustment is best made with a filled bag. Prior to removing the filled bag from the filling spout, verify that the weight of the bag is resting on the bag chair and not hanging from the packer spout. The paper (or plastic) at the top of the bag should not be under tension. Incorrect bag chair adjustment is a common cause of off weight and bag size problems. Care should be taken that the bag chair position is high enough to allow the bag to fill out properly at the end of the filling cycle, especially in the upper portion of the bag. If the chair is not high enough, the bag capacity may be greatly reduced.

CAUTION: Improper use of the bag chair can cause damage to the weigh beam. Do not drop, stand or jump on the bag chair.


6. Maintenance

The CBE 900 must be kept clean and inspected periodically to ensure dependable service. Special attention should be given to:

1. Flexure Plates - The flexure plates should be kept perfectly parallel to one another and should also be kept perfectly perpendicular to the bag post.

2. Rubber Pinch Tube and Tube Bars - Check periodically for cracks that may develop at the pinch

point or for product wearing the tube from the inside out. If ballooning or bulging areas or splits occur, the pinch tube should be replaced immediately.

3. Filter Regulator – A minimum of 80 PSI should be maintained on the filter regulator at all times

during normal operation. Air pressure can be adjusted by a large hand knob at the top of the regulator. There is also a ¼ turn needle valve at the bottom of the regulator underneath the water trap bowl. This devise serves to separate some of the water out of your supply air before allowing it to enter into the bag filler. DRY AIR IS REQUIRED FOR PROPER OPERATION OF THIS EQUIPMENT. THIS REGULATOR WILL NOT SEPARATE ALL WATER FROM YOUR AIR SUPPLY. Special care and consideration should be made to ensure that the compressed air being delivered to the filler is clean and dry. Drain and clean weekly or daily if necessary depending on the humidity of your environment. If excessive contamination and water accumulate in the transparent bowl, it should be cleaned more often.

4. V-Belts- Should be checked periodically for wear and adjustments made for proper tension.

5. Stuffing Box- The Stuffing should be kept tight around the shaft. This can be accomplished by

tightening the four nuts on the stuffing box covers / lids to keep the stuffing inside the stuffing box under constant compression.

6. Magnetic Starter- Keep magnet mating surface free of any accumulated dirt or dust. DO NOT OIL

OR GREASE THE MAGNET MATING SURFACE. The silver contacts need only to be replaced when nearly all tip material is gone and contact tip support material is exposed. DO NOT FILE THE CONTACTS. The ultimate tripping current of installed relay heater can be adjusted +/- 15% by using adjustment dial, if necessary.

7. Air Assist - The flow control valve introduces a constant flow of air into the orifice of the housing.

The primary purpose of this air is to fluidize the material as it enters the orifice thus preventing plugging.

8. Air Cylinders – Air cylinders should operate smoothly and without jerking or halting movements.

Repair kits are available for many cylinders.

9. Bag Chair - Incorrect bag chair adjustment is a common cause of off-weights and bag problems. Care should be taken that the bag position is high enough to allow the bag to fill out properly at the end of the filling cycle, especially in the upper portion of the bag. If the chair is not high enough, the bag capacity may be greatly reduced.

10. Impeller Feeder - New design style impellers prevent the erosion of old style impellers but care

should be taken to observe the wearing down of the blades on impellers and feed screws. Abrasive products wear the blades down so too much material is allowed to move from the hopper into the fill spout which attributes to off-weights. New style hubs have hardened, removable blades which provide easier maintenance and are inexpensive to keep in stock for quick repairs.


CHAPTER 4

MECHANICAL INFORMATION


The CBE 900 Impeller Packer can be both automated and mechanical. The operator is required to put an empty bag on the filling spout activating the auto start with the empty bag in place. The bag is then filled and weighed automatically and when equipped with a powered bag chair, it is discharged automatically upon target weights are reached. If for any reason it is desired to interrupt the filling operation in the middle of cycle, a STOP pushbutton is provided. This is the Red pushbutton facing the operator. Pushing this button stops the packer as a safety precaution also. The following items and adjustments should be check ed before the packer is set up for operation.

1. Scale beam set-up. 2. Definitions and adjustments

• Pasted Bags: Place a bag on the fill tube and smooth the body of the bag down so the valve is snug on

the tube. Unfold the bottom of the bag to a horizontal position. Position the bag chair so it contacts the bag.

• Sewn Bags: Place a bag on the fill tube and smooth body of the bag down so the valve is snug on the tube.

For the first setting, position the bottom of the bag chair slot one-inch below the bottom of the bag. As the first bags are filled, make sure the bag chair provides proper support for good bag filling and discharge. A chair set too high will not allow the bottom of the bag to open properly and a bag chair set too low will not support the bag adequately for good discharge. Re-adjust the bag chair height if necessary.

• Regulator: Located on the back of the packer is the Filter, Regulator and/or Lubricator Assembly. The plant

air is introduced into this assembly through the filter and then to the regulator which is adjusted by turning the screw at the bottom of the regulator so the pressure gauge registers from 65 to 80 pounds of pressure.

• Flow Control: The flow control valve introduces a constant flow of air into the orifice of the housing. The

primary purpose of this air is to fluidize the material as it enters the orifice thus preventing plugging. • Bag Chair: Incorrect bag chair adjustment is a common cause of off-weights and bag problems. Care

should be taken that the bag position is high enough to allow the bag to fill out properly at the end of the filling cycle, especially in the upper portion of the bag. If the chair is not high enough, the bag capacity may be greatly reduced.

The following items should be inspected frequently.

• Flexure Plates - these should be kept properly adjusted for accurate scale performance. • Load Cells - should be handled carefully and should properly register bag chair loads to the controller.

• Pinch tube- should be smooth and regular without ballooning or bulging areas or splits.

• V-Belts - check periodically for wear and adjustments for maintaining proper tension.

• Stuffing Box - covers / lids should be kept tight and the stuffing maintained in clean condition. To tighten lid

make sure the four nuts on the box are secure and tight. If excessive leaking is occurring, replacing of the stuffing boxes me be required.

• Cylinders - cylinders should operate smoothly and without jerking or halting movements. Repair kits are

available for many cylinders.


• Impellers - New design style impellers prevent the erosion of old style impellers but care should be taken to

observe the wearing down of the blades on impellers and feed screws. Abrasive products wear the blades down so too much material is allowed to move from the hopper into the fill spout which attributes to off-weights. New style hubs have hardened, removable blades which provide easier maintenance and are inexpensive to keep in stock for quick repairs.
