Obviously, the existing counting method cannot meet the working requirements of this new knitting control system and knitting needle combination
[0005] In addition, the method of using the electromagnetic proximity switch to determine the position of the knitting head still has the following disadvantages: first, the signal sent by the proximity switch only contains position information, not the running direction information; second, the price of the electromagnetic proximity switch is high and the installation requirements are high. (Because the magnetic induction range is within 1 mm, the installation accuracy is also within mm), which increases the manufacturing cost

Embodiment Construction
[0020] Referring to FIG. 1 , counting racks 10 are respectively arranged on both sides of the needle bed 30 , and the counting racks 10 are placed along the running direction of the flat knitting machine head. Three photoelectric sensors 20 are installed side by side on the flat knitting machine head 31, and its position corresponds to the position of the counting rack 10, so that when the flat knitting machine head is in operation, the counting teeth on the counting rack are on a pair of each photoelectric sensor 20. The light-emitting tube and the light-receiving tube pass through to generate a counting signal corresponding to the position of the needle slot on the needle plate corresponding to the position of the counting teeth.
[0021] With reference to Fig. 2, the counting rack 10 corresponding to one side of the movable needle plate 32 needs to move when performing transfer knitting, and the counting rack 10 must maintain a one-to-one correspondence with the needle groov...

The invention relates to a counting method of the transportation load of a flat knitting machine head with the one-to-one correspondence with a needle trough position. A machine tool and a knitting machine head are installed on a flat knitting machine. A counting rack is arranged on both sides of the machine tool. The counting rack corresponding to one side of a moving needle plate is linked with the side of the moving needle via a connecting plate. Three photoelectric sensors are arranged in parallel on the flat knitting machine head corresponding to the counting rack, so a counting gear on the counting rack moves between a pair of the luminescent tube and the photic tube of the photoelectric sensor to respectively generate a counting signal corresponding to the needle trough on the needle plate on both sides of the counting gear. The space width of the counting gear B is equal to 3t. The mounting distance between two photoelectric sensors and a standard photoelectric sensor respectively is that L1 is equal to nB+1 and L2 is equal to nB+2t. The counting method has the advantage that the signals of location counting and the signals of displacement direction have one-to-one correspondence with the needle troughs, thus facilitating a computer for controlling. Once the photoelectric sensor goes wrong, an error can be judged and eliminated at once. In addition, the sensor can sense the location accurately, and the cost in manufacturing and mounting is low.
Description
technical field [0001] The invention relates to a computerized flat knitting machine, in particular to a method for counting the running volume of a flat knitting machine head corresponding to the positions of needle grooves one by one. Background technique [0002] When the flat knitting machine performs pattern knitting, the knitting control mechanism on the knitting head needs to select the knitting needles in the corresponding needle slots on the needle bed, which requires measuring the running volume of the flat knitting head on the needle bed , to determine the position of the selected needle. [0003] At present, the measurement of the running amount of the horizontal knitting head on the needle bed is realized in this way: a counting rack is set on the needle bed along the running direction of the horizontal knitting head (that is, the direction in which the needle groove is arranged on the needle bed), and the counting rack is connected to the needle. The needle sl...
