That is, in FIGS. 2 and 3, a knitting machine cylinder b is rotatably fitted through a bearing c to a machine frame a that is integral with the table of the circular knitting machine 1. A large number of needle grooves d are formed in the vertical direction on the outer circumference of b. A well-known jack (not shown) and a knitting needle e are provided in the needle grooves d so as to be slidable in the vertical direction, and the machine frame a located at the lower part of the jack on the rotary passage. Is provided such that a chevron-shaped lifting cam moves up and down the jack and the knitting needle e together. Further, a well-known sinker bed or top ring is attached to the upper part of the knitting machine cylinder b, and a large number of sinker grooves are formed in the sinker bed radially with respect to the axis of the knitting machine cylinder b. Has been done. Further, each sinker f for knitting a stitch is loosely fitted in each sinker groove, and this sinker f is a sinker cam of a sinker cap provided on an upper table integral with the machine frame a. The knitting machine cylinder b is provided slidably in the front-rear direction with respect to the axial direction.

On the other hand, in the machine frame a located outside the jack,
A box-shaped protective frame is attached, and a patterning device (needle selecting device) g is provided on the protective frame. Further, a dial member of the dial mechanism h is concentrically provided above the shaft center of the knitting machine cylinder b, and the rotary shaft of the dial shaft of the dial member is the rotation of the knitting machine cylinder b. It is mounted via a bearing so as to rotate synchronously. Further, a rotary disk i is horizontally extended to the upper part of the outer circumference of the knitting machine cylinder b on the rotary shaft, and a known transfer jack for knitting is used at the outer end of the rotary disk i. Is attached. Further, the dial member and the rotary disc i immediately above the transfer jack are provided with a thread cutting cutter composed of a fixed cutter and a movable cutter (circular cutter). The thread cutting cutter is used for cutting a thread end. It is designed to be applied. Furthermore, a yarn feeding device j having a large number of winding cones of knitting yarn is installed in the machine frame a near the dial mechanism h.

On the other hand, as shown in FIG. 3, a pulse motor 2 is installed below the machine casing a, and a rotary shaft (not shown) that rotates in synchronization with the knitting machine cylinder b has
A rotation speed detection sensor (knitting machine course) 3 is connected.
Further, as shown in FIG. 2, a rotary cam (drum cam) k is mounted on the rotary shaft 2a, and a swing arm rod m is provided on the machine frame a beside the rotary cam k. It is pivotably attached to a support shaft n. Furthermore, the free end m1 of this swing arm rod m
Is in contact with the outer periphery of the rotary cam k, and the engaging pin o attached to the middle of the swing arm rod m is the engaging portion of the lifting cylinder p provided below the knitting machine cylinder b. It is connected by engaging with p1.

On the other hand, as shown in FIG. 3, the rotation speed detection sensor 3 of the circular knitting machine 1 includes a main CPU (main central processing unit) 4
Are connected via an input / output control circuit (I / O controller) 5, and a main memory circuit 6 and an input / output circuit 7 are connected to the main CPU 4. In addition, this input / output circuit 7
For example, a data storage means 8 such as a floppy desk (FD) has previously inputted all the data necessary for knitting stockings, and this data storage means 8 passes through the input / output circuit 7 to the main CPU 4. Connected to enter. Further, the main CPU 4 is provided with a pulse motor driver 9 connected to the pulse motor 2.

That is, the knitting control device of the circular knitting machine shown in FIG. 3 is, for example, a knitting control device provided with a standard program (reference program) into which all data necessary for knitting stockings is input.

Therefore, the knitting control device of the circular knitting machine described above, for example, when knitting while adjusting the stitches of the stocking, stores the data previously stored in the main memory circuit 6 or the auxiliary memory circuit (not shown) in the main CPU 4 To the input / output control circuit (I / O controller) 5 based on the data calculated by the main CPU 4 by the signal from the main memory circuit 6
And the pulse motor 2 is transmitted to the pulse motor 2 via the pulse motor driver 9 to control the rotation angle of the pulse motor 2, so that the pulse motor 2 is connected to the rotation shaft 2a as shown in FIG. Since the integral rotary cam k rotates, the rotary cam k swings the swing arm rod m around the support shaft n. Then, since the locking pin o of the swing arm rod m moves up and down, the engaging portion p1 of the elevating cylinder p is moved up and down, so that the elevating cylinder p has the bearing c and the connecting rod. Since the knitting machine cylinder b is moved up and down via q,
As a result, the knitting needle e of the knitting machine cylinder b and the sinker f cooperate with each other to freely control the size of the stitches of the knitted fabric.

In this way, the knitting control device for the circular knitting machine described above is not limited to, for example, not only the stitch adjustment of stockings, but also, for example,
The pattern of the stocking and the size and shape of the stocking are knitted and controlled by the control circuit shown in FIG.

(Problems to be solved by the invention) However, the knitting control device of the circular knitting machine provided with the above-mentioned standard program, for example, not only adjusts the stitches of the stocking but also determines the pattern of the stocking and the size and shape of the stocking. Although knitting is controlled by the control circuit, this knitting yarn is caused by fluctuations in the tension of the cone around which the knitting yarn is wound during knitting of stockings, atmospheric temperature, atmospheric humidity, and material of the knitting yarn. Since it is easy to expand and contract to change the predetermined size and shape, stitches and patterns, and it is difficult to knit a product of uniform quality, conventionally, the operation of the circular knitting machine must be stopped each time. During the knitting of the stockings, the operator can "consider" the fluctuation of the tension of the cone around which the knitting yarn is wound, the atmospheric temperature, the atmospheric humidity and the material of the knitting yarn.
Since a product of uniform quality is knitted by making corrections depending on the above, it is not only difficult to knit a large number of products to uniform quality, but labor saving by mass production cannot be performed.

The present invention has been made in view of the above circumstances, while continuing the operation of the circular knitting machine, without relying on the intuition of the operator, for example, of a cone in which a knitting yarn is wound during knitting of stockings. Circular knitting machine designed to automatically detect and correct tension fluctuations, atmospheric temperature, atmospheric humidity, knitting yarn material, etc. with each detection sensor to knit products of uniform quality and to save labor through mass production. It is an object of the present invention to provide a knitting control device of the above.
