Description

Method and device for turning without suction The present invention

  relates to a method and a non-suction turning device for returning articles

tubular elongated flexible.

  Some items usually require return during manufacture, including items of clothing

  such as unfinished hosiery. The return-

  swimming is a common means used, for example in hosiery, to close the toes and / or to check machines; it is usually carried out using suction tubes. Suction turning equipment

  satisfactory when it comes to returning

  individual keys, but they are not well suited to return very long items, such as the tube made of many hosiery items sewn end to end. In addition, it can be difficult and expensive to set up

such suction devices.

  An object of the invention is to provide a method and an arrangement

  fast, simple and low cost, which are not based on suction and involve a minimum of

  participation on the part of the user.

  According to a first aspect, the invention provides a method of turning a flexible elongated tubular article, wherein an end portion of this article is placed within an elongate gutter-shaped body, its end is manually threaded. through a ring at one end of the body, is manually turned back on itself on the ring and is pulled partially out of the body, a wheel

  or winding roller co-operating in rotation

  continuation with the end of the article placed outside the body to pull this article completely on the body after passing along the gutter and the ring, returning

so the article.

  In a second aspect, the present invention provides a non-aspirating turn-over device for turning a flexible elongate tubular article, having an elongated body on which the article will be turned and a winding wheel.

  can be rotated to pinch the article into

  its periphery and the outside of the body so as to pull the article on the body, the latter having a gutter to guide the article to return to a turn-ring at one end of the body adjacent to the wheel

  the article being, when using this provision,

  sitive, threaded through the ring and returned to him-mime

on the ring and on the body.

  The invention will be better understood on reading the description of

  detailed description, given below by way of example only, in conjunction with the attached drawing in which:

  FIG. 1 is a front perspective view of the device

  tif turning according to the invention.

  FIG. 2 is a side view of this return device

  swimming in cooperation with a vapor separator or water and steam, which is shown schematically in phantom. The turning device 10 is basically constituted

  by a vertical body 11, on which

  tubular keys, for example uncompleted socks,

  and a winding wheel or roller 12. The inferior end

  the upper body 11 is housed in a mounting boss 13, which is the only means of support of the body. In the body 11 is formed a gutter section 14 in which the tubular articles are drawn for turning purposes. At its upper end, the body has a turn-up ring 15, which is raised outward and upward like a funnel. To retain the tubular article within the gutter section 14, the body 11 is equipped with several (here two only) retaining members 16 and 17 spaced apart from each other. These retainers 16, 17 cover the gap between the edges 18 of the section

gutter 14.

  Most suitably, the body 11 is machined in a tube; the holding members 16, 17 may be integral with the tube or separate parts welded or brazed to the tube. The funnel-shaped ring 15 can likewise be attached to the body. The lower end

  of the latter has an enlarged opening 20 for ease of

  the introduction of the tubular article to return.

  The retainer 17 is located in the immediate vicinity of

the adjacent opening 20.

  The winding wheel 12 can have any axial profile suitable for

  and a soft coating, for example cellular rubber

  in order to have a good grip by friction on the tubular article. This wheel is rotated by

  an engine, not shown, in a direction such that the

  tubular ticle is pulled down on the body. In the neighborhood

  swimming from the lower end of the body 11 lies a

  stop collar 21 for the tubular article.

  the body 11 and the driving wheel 12 are arranged to be able to move towards and away from each other between an active position, of winding, and a rest position, of loading. the body 11 and the wheel 12 can either, or both, be mounted so as to be movable, but usually it is preferred that the wheel 12 rotates about an axis of rotation fixed and that the body It can pivot in both directions to cooperate with the wheel and disengage (see the arrow in Figure 2). For this purpose, the mounting boss 13 may be mounted on pivots (not shown) to allow pivoting movement

around the axis 22.

  In use, a tubular article, such as unfinished open end socks, connected end-to-end, is manually fed through one end into the bottom of the body 11 through the enlarged opening 20, and under (or

  behind the figure) the retainer 17. Oette

  mite is then drawn to the iut in the droplet section.

  14, behind the retaining element 16, and is finally

  The last manual operation is to turn this end over itself on the ring and see the bottom on the outside of the body until it is arranged. at the height of the winding wheel 12 or just below. At this stage, most of the tubular article is outside the body 11, and there is only its front end between the

  above the body and the winding wheel that is turned over.

  the body 11 is then tilted towards the winding wheel 12 to pinch the front end of the tubular article between

  the outside of the body and the wheel, which is then

  che to pull the tubular item down on the body.

  At this moment, the rest of the tubular article is pulled into

  inside the gutter, and upwards, which

  guide the article to the turn-up ring 15, the article finally being disposed outside the body at

the state completely returned.

  The length of the tubular article, and thus the number of unfinished socks that can be completely turned over, depend on the length of the body between the winding wheel 12 and the stop collar 21, the length

  each uncompleted individual sock and thick

  knitting. For men's socks of length and

  medium thickness, it is possible to return

  40 uncompleted socks connected together.

  After turning over, the tubular article is simply pulled by the upper body for further processing. For example, the tubular article can be separated into individual articles

not completed.

  Figure 2 schematically shows separation equipment

  Associated with which can be used the turning device 10, equipment in which the unfinished individual articles are sewn end to end by a wire sensitive to heat and moisture. The separator 30 comprises a box

  with steam or steam and water 31 having greater openings

  upper and lower, each of which is crossed by a pair

  pinch rollers 32, 32x opposite. What was

  Tially the rear end of the tubular article becomes, after turning, the front end which is brought into the upper part of the steam box 31 between the rollers 32. When the tubular article descends through the box, the atmosphere therein degrades the sewing thread connecting the adjacent individual articles, these separated articles being evacuated on a discharge conveyor 33. The separation is performed by the pair of rollers 32 'at the discharge end of the box 31, these rollers 32 'being driven at a peripheral speed greater than the rollers 32 to

the input end of the box.

  The turning device shown is vertically mounted.

  but it can be positioned differently, for example

  to be horizontal, in which case the open side of the

must look up.

  Although it has been described here in connection with articles

  hosiery, the turning device 10 can be used

  used to return other flexible tubular products.
