    [037] The function of the feeding device 3 is to also feed the goods on the multi-line vibrator 4.
    [038] The function of the multi-line vibrator 4 is to accelerate the goods on the inside of its channel and align all units on the inside of the channel in order to prevent the units from overlapping, and the units go down to storage channel 7 with a port.
    [039] Camera 5 coordinates with the light source 6 the scanning of the descending units by means of a high speed and transfers the images to the camera controller.
    [040] The camera controller analyzes the images and counts the number of units.
    [041] The function of storage channel 7 is, when the number of units reaches a certain number, the lower door of the storage channel will open and the units with the certain number will be weighed in the counting and weighing feeder, and when the feeder counting and weighing is used in conjunction with one of the weighing feeders, a lower door should be designed at the bottom of the storage channel.

    [061] The method for using the electronic weight control packer for weighing additionally comprises the fact that the method for calculating the number of units is: calculating the units of the small sample each time, and the unit weight is calculated by the moving average or heavy moving average.
    [062] According to a method of the present invention, the method of calculating the weight of the weight of the individual unit can vary according to the different characteristics of the different goods. The method can be as follows:
    [063] use the small number of samples to calculate the unit unit by the moving average or the heavy moving average.
    [064] use 3 (three) times as an example:
    [065] The individual unit weight for the first time is A;
    [066] The individual unit weight for the second time is B;
    [067] The individual unit weight for the third time is C.
    [068] The first individual unit weight a is obtained by averaging A, B, C (or heavy average).
