Embodiment
The embodiment of the present invention is explained with reference to the accompanying drawings.
As depicted in figs. 1 and 2, yarn tension monitoring device of the invention, for monitoring relative second yarn of the first yarn 100
The Tensity size of line 200, including：Bottom plate 10, the first movable pulley 20, the second movable pulley 30, swept resistance silk 40, contact 50 and inspection
Survey module 60.
The bottom plate 10 is fixed provided with slide rail 11, the first fixed pulley 21, the second fixed pulley 22, the 3rd fixed pulley 31 and the 4th
Pulley 32, the fixed pulley 22 of the first fixed pulley 21 and second is located at the both sides of the slide rail 11, the 3rd fixed pulley respectively
31 and the 4th fixed pulley 32 respectively be located at the slide rail 11 both sides, the slide rail 11 be provided with the first sliding block 12 and the second sliding block
13, the sliding block 13 of the first sliding block 12 and second can relatively described slide rail 11 slide, the sliding block 13 of the first sliding block 12 and second
It is fixedly connected by connecting plate 14, the connecting plate 14 enables the sliding block 13 of the first sliding block 12 and second in the slide rail 11
Upper synchronizing moving.
First movable pulley 20 is arranged on first sliding block 12, and the first yarn 100 bypasses described first successively to be determined
Pulley 21, the first movable pulley 20 and the second fixed pulley 22, the first fixed pulley 21 and the second fixed pulley 22 can play seal wire effect.
Second movable pulley 30 is arranged on second sliding block 13, and the second yarn 200 bypasses the described 3rd successively to be determined
Pulley 31, the second movable pulley 30 and the 4th fixed pulley 32, the 3rd fixed pulley 31 and the 4th fixed pulley 32 can play seal wire effect；
The swept resistance silk 40 is arranged on the connecting plate 14, and its one end is provided with contact chip 41；
The contact 50 is fixed on the bottom plate 10, and its head is contacted with swept resistance silk 40, passes through the cunning
Move the movement of resistance wire 40 to change the contact point of the contact 50 and swept resistance silk 40, so that the contact chip 41
Different resistance values are obtained between contact 50；
The detection module 60 is electrically connected with the contact chip 41 and contact 50 respectively, for detecting the He of contact chip 41
Resistance value between contact 50.
The bottom plate 10 is provided with sheet metal 15, and the sheet metal 15 be arranged in parallel with the slide rail 11, the contact chip
41 head is contacted with the sheet metal 15.The contact chip 41 of 40 ends of swept resistance silk is electrically connected with detection module 60 by wire
Connect, because swept resistance silk 40 is moved left and right, and wire also can be moved and then, may result in wire dropping, therefore, set gold
Belong to piece 15, the sliding contact on sheet metal 15 of contact chip 41, wire just can be directly connected on sheet metal 15, it is ensured that electrical connection
Reliably.
The two ends of the slide rail 11 are provided with positive stop 16, prevent the first sliding block 12 and the second sliding block 13 from departing from slide rail 11.
The yarn tension monitoring device of the present invention, when starting working, the head of contact 50 and swept resistance silk
40 contact points are located at the centre position of swept resistance silk 40, in the present embodiment the yarn on the basis of the second yarn 200,
Tension force is regulated by more accurate yarn tension-adjusting gear, then compared the tension force of the first yarn 100 with it.If first
The tension force of the tension force of yarn 100 and the second yarn 200 is essentially identical, the contact point of the contact 50 and swept resistance silk 40
Position is basically unchanged, and the resistance value between the contact chip 41 and contact 50 keeps stablizing constant.If of the first yarn 100
Power is more than the tension force of the second yarn 200, and the first yarn 100 can then pull the first movable pulley 20 to move, i.e., as shown in Figure 1 to moving to left
It is dynamic, while swept resistance silk 40 is also moved to the left with the first movable pulley 20, it is at this moment described because contact 50 is fixed on bottom plate 10
Resistance value between contact chip 41 and contact 50 becomes big., whereas if the tension force of the first yarn 100 is less than the second yarn 200
Tension force, the first movable pulley 20 and second pulley 30 can be pulled and moved by the second yarns 200, i.e., move right as shown in Figure 1, this
Resistance value between Shi Suoshu contact chips 41 and contact 50 diminishes.
According to the change of the size of resistance value, it can be determined that tension force of the tension force of the first yarn 100 with respect to the second yarn 200
The change of size.Therefore, the resistance value size detected is transferred to control module (not shown) by detection module 60, described
One tension force of the tension-adjusting gear of circular knitting machine is adjusted after control module is analyzed and processed according to the change of resistance value size
Entire signal, the Tensity size of the first yarn 100 is adjusted, and makes the tension force of the first yarn 100 and the tension force of the second yarn 200
Keep identical.The present invention is contrasted by the tension force between yarn, and the tension force of adjacent yarn is adjusted using tension-adjusting gear,
Apparatus for adjusting force can utilize existing Thread-feeding device, and the regulation to Tensity size is realized by the defeated yarn wheel speed of regulation thereon.When
When defeated yarn wheel speed is fast, thread-feeding amount is big, and yarn tension declines；When defeated yarn wheel speed is slow, thread-feeding amount is small, yarn tension increase.
The present invention can carry out the monitoring of yarn tension when implementing using multiple yarn tension monitoring devices of the invention,
Single or threads are equally spacedly selected on large circle machine or other knitting equipments as benchmark yarn, the tension force of the yarn can lead to
Cross more accurate monofilament tension detecting apparatus and set basal tension to detect.Make the tension force and the first benchmark yarn of adjacent yarn
It is roughly the same, and using this two one thread as the second benchmark yarn, and gradually produce the three, the 4th ... N benchmark yarns.From
And under the conditions of realization low cost, the tension stability of single channel yarn and the tension force of multichannel yarn are roughly equal.
As described above, the exemplary embodiments of the present invention are described in detail referring to the drawings.Should
Solution, the present invention, which is not intended to, makes these details constitute limiting the scope of the invention.Without departing substantially from according to this hair
In the case of bright spirit and scope, equivalent or similar change can be carried out to the structure and features of exemplary embodiments
Become, these changes will also fall determined by claims appended hereto in protection domain.
