Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a forming flat knitting machine that is capable of continuously and automatically individually knitting knits one by one.

Traditional knitting methods for sweater fabric include fabric knitting (jersey), sweater knitting (garment lenguene), and molded knitting (full fashion). Since the fabric is knitted continuously, there are various tasks such as taking measurements after knitting, cutting according to the pattern, overlocking the edges with an overlock sewing machine, and sewing the elastic knitted parts. Post-processing is required, and there are many threads that are cut during cutting, which increases the cost and involves green stitching, which gives a poor texture and is uncomfortable to wear when sewn into a sweater. However, it has always had various drawbacks.

In addition, in the case of sweater knitting, compared to fabric knitting, the post-processes of measuring dimensions and sewing the elastic knitting part can be omitted, but the thread removal process increases, and there are still many post-processes, which still have the same disadvantages as mentioned above. It depends. Furthermore, in the case of molded knitting, compared to sweater knitting, post-processing of cutting and overseaming is not required, and the texture and comfort are improved. There is a post process such as removing the knitted part,
However, it still has a disadvantage in that there is some thread loss in the removed threads and the threads in the discarded knitting section.

However, in the present invention, the take-down rollers conventionally used for winding down the knitted fabric are not used, but a set-up comb fixed to a chain that descends at a speed synchronized with the knitting speed of the flat knitting machine is used. When the knitted fabric reaches the garment length, the set-up comb is gradually raised and the stitches are removed from the needle hooks in the final knitting of the fabric using a carriage. The knitted fabric is automatically removed by the wind pressure from the air outlet connected to several stages of blowers behind the comb, and each garment can be knitted automatically and continuously. Compared to molded knitting, it has various advantages such as post-processes such as thread removal and removal of waste knitted parts, lower costs, and can be supplied to the sewing process immediately after knitting.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference numeral 1 designates a flat knitting machine in which, as is well known, a front needle bed 2 and a rear needle bed 3 are attached to the machine frame 10 side of the horizontal m machine 1 in a chevron shape as shown in FIG. Reference numeral 4 designates a set-up comb, which has a number of set-up pins 5 whose tips are curved in a semicircular shape embedded in a set-up plate 6. The needle bed 2 is disposed in the needle bed 2 and moves up and down through a gap 7 formed between the chevron-shaped front needle bed 2 and rear needle bed 3. 8 is Yokozuna machine 1 as shown in Figure 1.
A set of chain wheels rotatably supported on both sides of the
It is arranged close to the gap 7 below the rear needle bed 3. Reference numeral 9 denotes a set of chain wheels installed below each of the set of chain wheels 8, and as shown in FIG. They are each fixed to a chain drive shaft 13 which is supported by a bearing plate 12. Reference numeral 14 designates a set of chain wheels installed behind the chain wheels 8.9, each of which is rotatably supported by bearings 15 fixed to the base plate 11.

],,6ii A set of chain wheels installed in front of the chain wheel 14 and behind the chain wheel /l/8.9, which is connected to the chain drive shaft 13 of the -set of bearing plates 12.
The arm 18 is rotatably supported at the tip of an arm 18 whose base part is rotatably supported on a shaft 17 fixed to a shaft. 19
is a set of endless chains, each of which is installed on a set of chain foils 8, 9, 14', and 16 as shown in Fig. 1, and fixed on both sides of the set-up comb 4 as shown in Fig. 5. be. Reference numeral 20 denotes a torque motor connected to the tip of the drive shaft 18, whose rotational force changes in proportion to changes in current value based on commands from a known controller (not shown). When the command rotates in the direction of the arrow a, the rotation is transmitted to the chain drive shaft 13 and the chain wheel 9, and sets out the - pair of chains 19 and moves the chain wheels s and 9 in the downward direction of the comb 4 (arrow b).
, 14 and 16, and when the motor 20 rotates in the opposite direction (arrow C), the chain 19 of the pair is similarly rotated in the upward direction (arrow d) of the set-up comb 4, and the set-up The comb 4 is moved up and down through a gap 7 between the front and rear beds 2 and 3. 21 is a dog protruding from the side of the set-up plate 6, and 22 is a microswitch installed on the lower surface of the front needle bed 2.As shown in FIG. When the dog 21 rises to a position suitable for hooking, the dog 21 comes into contact with the lever 23 of the micro switch 22, stopping the rotation of the motor 20 in the upward direction d of the set-up comb 4, and at the same time, the flat knitting machine 1 stops knitting. This enables rotation in the downward direction in synchronization with the speed. 24 is a blower installed in the machine frame 1o at the lower rear of the Yokozuna plane 1, and a sixth blower is installed in front of the net fabric 26 knitted from the air outlet 25.
ρ1 shown in the figure is for blowing out air. 27 (l
-1. It is a bellows-shaped tube connecting the air outlet 28 of the blower 24 and the outlet 25, and is for easily changing the position of the outlet 25 depending on the shape of the net fabric 26 to be knitted.

Next, when using this, first, with no stitches on the front and rear needle beds 2.3 as shown in FIG.
Moreover, when the flat knitting machine 1 starts knitting, the comb 4
The 1/' lug 21 on the side comes into contact with the lever 23 of the micro switch 22, stopping the raising of the knitting comb 4 by the motor 20, and at the same time causing the motor 20 to lower the comb 4 in synchronization with the knitting speed at the horizontal ma1. Rotate in the direction. At this time, the set-up pin 5 hooks the first hitch stitch knitted by the back kenpo 8, and descends while pulling the net fabric 26 with a constant tension due to the constant rotational force of the torque motor 20. In addition, the knitting speed of the Yokozuna machine 1 may be changed for various reasons, and in that case, the value of the current flowing through the torque motor 20 can be adjusted by turning a dial (not shown) provided on the controller. By adjusting the rotational force, a constant tension suitable for the knitted product can be obtained. The traction by the constant tension enables the next stitch to be knitted well, and the knitting is performed sequentially by the flat knitting machine 1. When the knitted fabric 26 reaches one garment length, by detecting the length, the controller stops the rotation of the knitting comb 4 of the motor 20 in the downward direction (arrow a), and at the same time A command is issued to cause rotation in the column direction (arrow C), and at the same time, the blower 24 is operated, and the net fabric 26 is rotated as shown in FIG.
Apply wind pressure in the front direction. At this time, the knitted fabric 26 swells up like a sail as shown in FIG. It will come off through the opening of the pin 5, which has an open direction. At the same time, by commanding the controller, the carriage performs a blank knit for the final knitting, and when the stitch is removed from the needle hook 30, the knitted fabric 26 is moved by the wind l1E31 of the blower 24, and the trajectory of the knitting comb 4. The knitted fabric 26 is blown forward from the surface, and the knitted fabric 26 can be automatically removed from the set-up comb 4. Further, the set-up comb 4 from which the knitted fabric 26 has been removed continues to rise, and when the dog 21 on the side comes into contact with the lever 23 of the microswitch 22, the motor 20 rotates the set-up comb 4 in the upward direction d (as shown by the arrow). C) is stopped, the cycle returns to the state shown in FIG. 2, and the cycle is completed. By repeating the cycles one after another, it is possible to automatically and continuously knit each garment individually in synchronization with the knitting speed of the flat knitting machine.
