Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Currently, the overseam needle pitch in industrial sewing machine is adjusted and is completed by mechanical linkage, with specific reference to the quarter on handwheel
Degree carries out rotation adjusting.This adjusting is by virtue of experience completed by staff, is not able to satisfy industrial high-precision.
The present invention detects the angle information of sewing machine hand-wheel and is converted to telecommunications by mechanical signal by angular transducer
Number, and then angle information is converted to by more intuitive needle gage value by controller, and show that staff is in hand using display
It takes turns in adjustment process using the needle gage value on display as adjusting according to, it can be achieved that efficient, accurate sewing needle distance is adjusted.
It is shown in Figure 1 the embodiment of the invention discloses a kind of detection regulating device of sewing needle distance, comprising:
Angular transducer 1, for obtaining the angle information of sewing machine hand-wheel；
Controller 2 is connect with the angular transducer 1, for the angle information to be converted to needle gage value；
Display 3, for being connect with the controller 2, showing the needle gage value, to adjust institute according to the needle gage value
State sewing machine hand-wheel.
Wherein, mechanical signal can be converted to electric signal by angular transducer 1, therefore angle information can be passed through route
It is sent to controller 2.Common angular transducer 1 includes Hall sensor and photoelectric encoder, because of the essence of photoelectric encoder
Du Genggao, therefore the present embodiment often selects photoelectric encoder.
By taking the photoelectric encoder of 720 lines as an example, sewing machine hand-wheel rotation one week is 360 °, and photoelectric encoder is according to AB signal
It is divided into 720*4 parts, that is, 2880 parts, minimum 0.125 ° of degree for can detecte, that is to say, that photoelectric encoder can for 360 °
The minimum degree numerical value for detecting sewing machine hand-wheel is 0.125 °, and precision is much higher than Hall sensor.
Specifically, angle information is converted to needle gage value by controller 2, then is shown by display 3, realize to needle gage value
Visualization regulation, staff can observe intuitive needle gage value on display 3 on one side, adjust on one side to sewing machine hand-wheel
Section, finally accurately obtains target needle gage value.
Further, the controller 2 can be also used for calculating the angle residual quantity of the angle information, and by the angle
Residual quantity is converted to needle gage residual quantity；The display 3 is also used to show the needle gage residual quantity simultaneously.
It is understood that needle gage residual quantity has extracted sewing needle distance adjusting by the multiple processing to angle information
The reference quantity needed in the process, further increases adjustment speed.Wherein, angle residual quantity can be angle information in detection twice
Residual quantity is also possible to angle information and the comparative quantity of preset angle angle value that angular transducer 1 is detected and sent.
It is understood that the preset angle angle value is corresponding with default needle gage value, controller 2 is removed when obtaining needle gage residual quantity
The sequence that angle residual quantity is converted into needle gage residual quantity again is first calculated, also can use the needle gage value of angle information conversion and default
Needle gage value is compared to obtain needle gage residual quantity.
Further, controller 2 can be the original mainboard controller MCU of sewing machine, and controller 2 can also utilize angle
The needle gage value that sensor 1 is sent, adjusts the other parameters of master control system, to cooperate the adjustment of needle gage value to reach more preferably control effect
Fruit.
It adjusts and shows on the display 3 that is, controller 2 can carry out various calculating using angle information, specifically
Suitable content the present embodiment is without limitation.
Wherein, display 3 is mainly used for showing needle gage value in the present embodiment, and type includes but is not limited to digital-scroll technique
Pipe and liquid crystal display.Other than display 3, other media can also be used to transmit the specific letter of needle gage value to staff
Breath, such as voice broadcast, can also when adjustment process mid-cut value exceeds allowed band in the form of acousto-optic etc. to master control system
Alarm is issued with staff to remind.
The invention discloses a kind of detection regulating devices of sewing needle distance, comprising: angular transducer, for obtaining sewing
The angle information of machine handwheel；Controller is connect with the angular transducer, for the angle information to be converted to needle gage value；
Display is connect with the controller, for showing the needle gage value, to adjust the sewing machine hand according to the needle gage value
Wheel.The present invention passes through angular transducer, detects the angle information of sewing machine hand-wheel and is converted to electric signal by mechanical signal, into
And angle information is converted to by more intuitive needle gage value by controller, and show that staff is in handwheel tune using display
Using the needle gage value on display as adjusting according to, it can be achieved that efficient, accurate sewing needle distance is adjusted during section.
The embodiment of the invention discloses a kind of detection regulating devices of specific sewing needle distance, implement relative to upper one
Example, the present embodiment have made further instruction and optimization to technical solution.Specific reference to shown in Fig. 2:
The detection regulating device further includes the adjusting sensor 4 connecting with needle gage adjusting rod, in which:
When the needle gage adjusting rod is pressed into predeterminated position, roll adjustment signal is sent to described by the adjusting sensor 4
Controller 2；
The controller 2 cuts off the control signal of motor.
It is understood that needle gage adjusting rod is equivalent to the whether adjustable switch of sewing machine hand-wheel, only when needle gage is adjusted
Bar is pressed into predeterminated position, and sewing machine hand-wheel just enters adjustable state.
And in the present embodiment, the location information of needle gage adjusting rod is converted to by electric signal by adjusting sensor 4 and is sent to
Controller 2 is learning that sewing machine hand-wheel in adjustable state, will appear the case where staff manually adjusts it at any time
Under, it is in security consideration, the control signal of motor is cut off by controller 2, leaves the motor off operation, guarantees worker safety.
Wherein, the adjusting sensor 4 is specially Hall sensor or limit switch.
By taking Hall sensor as an example, when using adjusting sensor 4, need that magnet steel is embedded in above needle gage adjusting rod in advance,
The installation and adjustment sensor 4 below needle gage adjusting rod, when needle gage adjusting rod is pressed against predeterminated position, magnet steel and adjusting sensor
High level signal is transmitted at controller 2 by 4 distance change so that adjusting the signal of sensor 4 becomes high level from low level
Reason；Once needle gage adjusting rod position is restored, adjust 4 signal of sensor becomes low level again, and controller 2 releases the stopping of motor
State.
As it can be seen that the signal of this circuit transmitting is sensitive reliable, safety is very high, can guarantee the safety in production of factory.
Correspondingly, the invention also discloses a kind of detection adjusting method of sewing needle distance, it is shown in Figure 3, comprising:
