Description

[Detailed Description of the Invention] The present invention relates to a device for dividing continuously knitted sock fabric, and is characterized in that a pre-knitted cutting course is evenly expanded, aligned, and divided.

Since the sock fabric knitted by conventional double-cylinder sock knitting machines (rib knitters) is continuously knitted, it must be divided into units and then transferred to the step of overlocking the open toe portion. This dividing work can be done manually by cutting and removing a part of the knitting yarn in the section of the long sock fabric that is removed from the sock knitting machine, or by using a machine attached to the double cylinder sock knitting machine. Remove the winding roll and install a new blower.
A separator device is used that removes the knitting yarn from the needle at the knitting opening of the cylinder and separates it using the suction force of air. However, the former is a work that is tiring for the eyes, has low work efficiency, and often results in defective products due to the scissors being accidentally inserted in a position other than the thread removal position, while the latter requires the needle or slider to be removed due to the thread being removed. In addition, there is a risk that the texture of the knitted fabric may be impaired because a certain tension is not applied to the knitted fabric by the take-up roll.

The present invention has been proposed in view of these circumstances, and its embodiment will be described in detail with reference to the drawings.The present invention will be described in detail with reference to the drawings.The present invention will be described in detail with reference to the drawings. 1' are erected in the longitudinal direction to form a lower guide member 1, and the lower guide member 1 is fixed to the upper surface of the side end portion of the substrate 2 with the blade portion 1' facing upward. An upper guide member 3 made of a long and thin sheet metal whose tip is cut obliquely is fixed to a bracket 4 standing on a substrate 2 so as to be vertically movable and with a desired gap maintained between it and the blade part 1' of the lower guide member 1. A platform 7 having a U-shaped cross section is slidably mounted on a flat prismatic guide member 6 fixed on the bed 5, and the tip of the elongated sheet metal is cut off diagonally, and the height and thickness are slightly reduced from the tip of the top surface. The movable lower guide member 8 is formed by vertically disposing a blade portion 8' having a blade portion 8′ upwardly, and the movable lower guide member 8 is placed on the upper surface of the side end of the pedestal 7 with the blade portion 8′ facing upward and the lower guide member It is fixed so that it is approximately at the same height as the blade part 1' of No. 1. The blade parts 1' and 8' are erected so that when the lower guide member 1 and the movable lower guide member 8 are joined together, the blade parts 1' and 8' are brought together. A bracket 9 having an L-shaped cross section is erected on the pedestal 7 so as to be attached to the side surface of the movable lower guide member 8, and an elongated hole 9' is bored in the rising surface of the bracket 9, and the tip of the elongated sheet metal is bent diagonally. The proximal end of the movable upper guide member 10 that has been cut out is fixed to the blade 8' of the movable lower guide member 8 with a fixing screw 11 inserted into the elongated hole 9' so that it can move vertically slightly and maintain a desired gap with the blade 8' of the movable lower guide member 8. do. A recessed groove 10' is obliquely cut out on the side surface facing the upper guide member 3 of the movable upper guide member 10, and a cutter 13 whose rear end is pivoted to the rear end of the lower guide member 1 with a pin 12 is used as an upper guide.

When the actuators of the switches 28 are brought into pressure contact with the discs 26 and the sock fabric 30 is brought into contact with the needle-like actuators of the micro-switches 29 fixed in place on the bed 5, the fabric expansion motor is activated.
When M ₂ is started and the disk 26 rotates once and the actuator of the micro switch 28 is indented into the recess 26', the fabric expansion motor M ₂ is stopped, and at the same time the disk 25 also rotates. When the actuator of the micro switch 27 enters the recess 25' with a delay, the micro switch 27 is activated and the cutter drive motor is activated.
(Time chart in FIG _. 7) The arrow shown in FIG. 8 indicates the cutting location of the sock fabric 30. Note that the sock fabric 30 has a cutting course 30' knitted in advance to be thinner than the fabric itself. In the figure, 31 is a gap adjustment screw.

Since the present invention is constructed in this manner, the lower guide member 1 and the movable lower guide member 8 are joined together, and the upper guide member 3 joins the sock fabric 30 together.
When the cutting course 30' of the sock fabric 30 is inserted into the gap formed between the movable upper guide member 10 and the micro switch 29 is touched, the fabric expansion motor _M2 is started and the cam C rotates. Fixed rod 19
