Description

[Technical field]

[0001] The present invention relates to the technical field of a tubular fabric knitting machine, in particular to the technical field of a tubular fabric turning device which can be moved transversely and has a top fabric device. [Background technology]

[0002] After the circular hosiery knitting machine has knitted the tubular fabric, it is often necessary to sew the tubular fabric. In the prior art, there is a device for picking up the tubular fabric woven by the circular hosiery knitting machine and transferring it to a sewing or crocheting station, where a sewing or crocheting head is provided, and the tubular fabric is sewed by the sewing or crocheting head. Usually, the picking device picks up the fabric from the circular hosiery knitting machine and optionally transfers it to the conveying device by respectively cooperating with the knitting coils on the knitting row at the end of the fabric, so that the knitting coils of the half row of the knitting row at the end of the fabric face the knitting coils of the other half row respectively before sewing or crocheting, so that the two coils of the two half rows facing each other of the knitting row are connected by the sewing or crocheting head, thereby playing the role of closing the end of the fabric.

[0003] In the process of automatically closing tubular knitted articles, the sewing or crocheting operation is usually performed on the fabric turned inside out, so that the sewing or crocheting chain loops are almost invisible on the front side of the fabric, that is, the side that is usually not visible when the fabric is worn, so that fabrics such as hosiery can achieve good results in terms of accuracy and aesthetics. The tubular fabric knitted by the circular knitting machine is usually facing outward, so when the tubular fabric is closed at the sewing or crocheting station, a turning mechanism is required to turn the tubular fabric inside out before undergoing the sewing or crocheting operation.

[0004] The most common type of turning mechanism is based on the use of a tubular body facing the fabric below, the fabric being supported at the axial end to be closed by a pick-up device or by an operating device, and the tubular body being arranged substantially vertically, the axial end pointing upward. The tubular body is also placed with its axis in a vertical position so that its upper axial end faces the suspended fabric. The inner part of the tubular body, in particular its bottom end, is then connected to a suction device so that the fabric is sucked in through its upper axial end, the fabric being held at the axial end to be closed by a pick-up device or an operating device. Thus, the fabric is placed in the tubular body. At this point, the tubular body is lifted through the axial end of the fabric, and the fabric engages with the pick-up device or the operating device. As a result, the inside of the fabric is turned out on the outer surface of the tubular body and gradually removed from the upper axial end of the tubular body, thereby turning it over. When the tubular fabric is too long, its drooping length is too long for the tubular fabric to enter the mouth of the suction pipe of the turning mechanism, and the tubular fabric cannot be sucked into the suction pipe.

[0005] Patent No. 2009801088587 discloses a turning device for tubular knitted articles, especially for automatically closing the sewing or crocheting station of the tubular articles at the axial end of the tubular articles, and discloses that, especially in the case of relatively long articles, the lower part can be tilted relative to the axis by a driving mechanism, so that the upper axial end of the tubular body connected to the suction device is closer to the machine for producing the articles. This proximity facilitates the article whose upper end is hung on the pick-up member of the pick-up device to be sucked into the tubular body through the upper axial end of the tubular body. Subsequently, the lower part is returned to position the axis of the tubular body at the axis. Although it can adapt to a range of tubular articles of a certain length, its tilting range is small, so that the adaptation to the range of tubular article lengths needs to be improved. In addition, socks such as harder or thicker socks (for example, made of special yarns) or constructed or shaped in a specific way (therefore with little elasticity) are difficult to be sucked into the suction tube. [Summary of the invention]
