Description
Technical Field
The invention belongs to the technical field of circular knitting machines, and particularly relates to a device and a method with a translation function for sewing tubular fabrics.
Background
Circular hosiery knitting machines often require sewing of tubular fabrics after they have been knitted. Devices are known in the prior art for picking up the tubular fabric knitted by circular hosiery knitting machines and for transferring it to a sewing or looping station provided with a sewing or looping head through which the tubular fabric is sewn. In general, the pick-up device picks up the fabric from the circular hosiery knitting machine and transfers it to the transfer device, optionally by cooperating respectively with the loops of knitting of the row of knitting of the end of the fabric, so that the half-rows of loops of knitting of the row of knitting of the end of the fabric face respectively the other half-rows of loops of knitting before the sewing or looping, so as to join the two loops of the two half-rows of knitting of the row facing each other by means of the sewing or looping head, thus acting to close the end of the fabric.
In the process of automatically closing tubular knitted articles, the sewing or looping operation is usually carried out on fabrics turned inside out, so that almost no sewing or looping stitches are visible on the front side of the fabric, i.e. on the side not normally visible when the fabric is worn, so that fabrics such as hosiery can be obtained with good results in terms of precision and aesthetics. Tubular fabrics produced by circular knitting machines are generally right side out and therefore require a turner to turn the tubular fabric inside out before it is subjected to the sewing or looping operation when it is closed at the sewing or looping station.
The known flippers are basically tubular structures, which are positioned under a gripper or pick-up device that grips the bottom closed end of the tubular fabric, with the upper end of the tubular structure facing the suspended fabric, then the inside of the tubular structure is connected to a suction device, so that the suspended fabric is sucked through its upper end, and then the tubular structure is raised to pass with its upper end through the to-be-closed end of the tubular fabric, while during the passage the fabric is turned inside out onto the outer surface of the tubular structure, turning the inside out.
Patent No. 2009801088587 discloses a device for turning over a tubular knitted article, in particular for automatically closing a sewing or looping station of the tubular article at an axial end thereof, comprising a lower portion and an upper portion, the upper and lower portions being respectively arranged below and above a middle region at which is arranged or arrangeable a device for supporting the tubular article to be turned over, the tubular article being suspended and substantially vertically arranged at an axial end thereof; and a tubular body insertable with its upper axial end from the bottom upwards through the axial end of the article suspended on the support means after having sucked it through the upper axial end of the tubular body, so as to cause the article held by the support means to be everted onto the outer lateral surface of the tubular body, the article being progressively extracted from the upper axial end of the tubular body, the eversion means comprising auxiliary sliding means movable on command with respect to the tubular body parallel to the axis of the tubular body and periodically engageable and disengageable with respect to the article everted onto the outer lateral surface of the tubular body, so as to generate a sliding of the article towards the lower axial end of the tubular body. The auxiliary sliding device is used for pushing down the object outside the tubular body, and the air suction in the tubular part is used for sucking the object from the lower part of the tubular part, so that the object which is sewn and turned outwards is turned over again. Although the device basically meets the requirement of turning over the fabric, the whole device is too complex in structure, and the auxiliary sliding device frequently breaks down when in use, so that the machine is stopped due to failure or the tubular fabric is damaged, and the device is not suitable for wide-range popularization. And the final finished product of the tubular fabric is outward in front, the suture line or the crocheted line is inward, the tubular fabric still needs to be turned outwards during the quality inspection of a factory, and the sewing effect is detected, so that the device turns the front out from the inner side at last, the quality inspection process of the factory is increased, and the labor cost is increased.
