Then step on the switch. When the filling operation is just started, the operator should put the opening of the down and feather suction pipe close to the down and feather for quick suction; When the filled weight approaches 250 grams, the suction pipe should be raised a little for reducing the suction speed; when the filled weight reaches 250 grams, switch off the filling machine. Repeat the procedure for the next bar. When the operation goes on, the weight of down and feather in the box should be displayed as 1500, 1250, 1000, 750, 500, 250 and 0.
Advantage: There is no error in the total weight of each quilt.
Disadvantage: There may be errors for the weight filled in each bar if the operation is not done proper enough, and the over-filled down and feather in the bar is difficult to take out.
(3) Continuous filling method
Applicable for: Large scale production in factory
No. of Worker: 2
Equipment: 1 big down and feather holding box 750 x 650 x 700 (mm), 1 electronic desk scale with big weighing capacity ( 30 kilograms ± 2 grams ). 1 desk type down and feather stand with declined desk surface, length 1200 mm, one side is 1000 mm and the other side is 859 mm in height. The desk surface edge protrudes out for 150 mm over the big down and feather holding box. There is a 100 mm deep arc–shaped trough across the 600 mm wide desk surface to prevent the down and feather bag from rolling.
Method: Put a whole bag of down and feather on the stand. Fill the holding box full without caring about the weight. Press the “ tare deduction “ key to make the weight displayed as “0”. Then step on the switch. Switch on the filling fan. When the filling operation is just started, hold the suction pipe with your left hand close to the down and feather for quick suction. When the sucked weight approaches 250 grams, raise the suction pipe a little to reduce the suction speed. At the same time, feed the suction pipe with down and feather with your right hand until the sucked weight is exactly 250 grams. Switch off the down and feather filling machine. Repeat the operation for the next bar until all the 6 bars are filled with down and feather. The sucked weight should be displayed as 0, -250, -500, -750, -1000, -1250, -1500. During the waiting time for the filling operation between two quilts, add more down and feather into the holding box and loosen down and feather lumps to avoid blockage in the suction pipe during operation.
Advantage: It is the quickest filling method. Within 8 hours working time 200 pieces of 8-bar type down and feather quilts can be filled; What is more, the total weight error for each quilt or mattress is very small.
Disadvantage: The two operators must be well coordinated; There may be errors for the weight filled in each bar if the operation is not done proper enough, and the over-filled down and feather in the bar is difficult to take out.
(4) Automatic down and feather filling machine
Two automatic weighing barrels are used to weigh down and feather in turn. The operator need only insert the filling pipe into the quilt or mattress, and the machine will automatically blow in the weighed down and feather from the barrel.
Advantage: A. Filling speed is 30 % quicker than manual operation.
B. The working site is in good order and looks luxurious.
Disadvantage: Its price is expensive
The machine occupies 20-30 M2 of area.
Filling weight is sometimes more than fixed errors.
The feather automatically circles for many times, and the consumption is large.
