Definitions
- the present invention relates to a device for opening or spacing the end of a fabric tubular manufactured product, such as for example a knitted stocking.
- two manufactured products can be directed to a machine called "line-closer" which provides the longitudinal section of the portion more elastic of manufactured products, appropriately invested in pairs of shapes support twinned, to allow assembly in pairs by means of a seam in matching edges that have been cut.
- the main object of the present invention is that of proposing a device specially usable in the manufacture of products manufactured of the above type which allows integrating several parts of a productive installation including machines for closing the tip and / or for assembly of tights and automation of transfer phases of manufactured products in way from one machine to another.
- Another object of the present invention is that of achieve a good reduction in time relating to total processing cycle of manufactured products and, at the same time, improving the quality of finished manufactured product.
- the advantages which derive from the present invention basically consist of what is possible operate automate product transfer manufactured from one machine to another from the production facility, regardless of the nature of the manufactured product, i.e. either whether they are tubulars intended for production of each stocking and either be tubular intended for the assembly of tights; that it is possible to reduce the time and cost of each production cycle; that a device according to the invention is manufacturing simple, economical and reliable even after a while extended use.
- a device for the opening or spacing of the end elastic (10) of a tubular manufactured product (1) knitted, such as a stocking comprising a body (T) of basically tubular shape, with an inlet section (I) at the end elastic (10) of manufactured products (1) to dealing and communicating with a separate section (S) slaved to air suction means in programmable sequence, where between said two sections (I) and (S) is arranged a conduit (2) converge-divergent downstream of which, at a distance predetermined, there is a pin member (3) on which the elastic end (10) of the product manufactured is intended to invest spontaneously by effect of the suction carried out through said section (S) and expansion or opening following its passage in the zone (20) downstream of the conduit (2): said body (T) being in two separable portions from a plane central longitudinal (X-X) at least in correspondence of said pin member (3) for allow the removal of the manufactured product (1) with elastic (10) in the relaxed position determined for the separation of said two
- said body (T) can be produced by two equal coincident parts, in position closed, in correspondence of the simmetry plane longitudinal (X-X). Said two parts of the body (T) are opposite with respect to the plane (X-X) in position of the elastic (10) manufactured product (1).
- means for regulating the forward speed of the manufactured product (1) in the body are provided, with a pair of slave calender rollers (4) to elastic means - not shown - and intended to compress the fabric of the product manufactured (1) in progress.
- Means of speed regulation of the manufactured product (1) functionally equivalent to those that have been described can also be used.
- the body (T) in intermediate position between section (I) inlet of the manufactured product (1) and the conduit (2), has a plurality of holes peripherals (5) to create a zone corresponding turbulance in the body (T) which promotes the opening of the elastic (10) in the case it is wrapped on itself or in flattened position.
- Near section (S) subject to resources suction body (T) can have advantageously a plurality of openings or slots (6) capable of promoting greater uniformity of suction in correspondence of the pin (3).
- Food for manufactured products (1) that is to say the introduction of products through the mouth or entry section (I) of the body (T) can be done by hand or by placing the body (T) at the outlet of an apparatus for automatic debit of manufactured products of a container, for example of the type described in the IT patent application FI96A163.
- the elastic With the successive opening of the body (T), i.e. with the separation of its parts by relation to the central longitudinal plane (x-x), the elastic is moved aside later, as it is illustrated in Fig. 2, and it can be withdrawn even with mechanical means, for example of the type described later.
- Said separable parts of the body (T) can both be mobile on command of one or several mechanical or pneumatic devices separation correspondents or, as shown in Fig. 2, one part (A) is fixed and the other (B) movable and slaved to a pneumatic cylinder (100) which moves it from and to fixed part (A).
- said means comprise a system of air flow interceptors suction systems controlled by control means already known by the industrial automation technicians and, therefore, not described in detail.
- a device according to the invention can be used to feed the tubes (8) of a needle sewing machine (MC): the device is placed upstream of the machine (MC) and to that -this is associated with a transfer device for manufactured products (1) with the spread elastic, for example comprising a plurality of hooks (90) carried by movement chains (9) slaved to a drive member (92) with a chain transmission (93) closed in a ring and placed on two opposite sides of the device itself, which is arranged, for example, so as to result parallel to the tubes (8) and with the section (I) sufficiently close to the surface of the mouths ( 81) of these.
- a transfer device for manufactured products (1) with the spread elastic, for example comprising a plurality of hooks (90) carried by movement chains (9) slaved to a drive member (92) with a chain transmission (93) closed in a ring and placed on two opposite sides of the device itself, which is arranged, for example, so as to result parallel to the tubes (8) and with the section (I) sufficiently close to the surface of the
- the activated suction in the tubes (8) therefore determines the introduction into the latter of the end of the manufactured product (1) opposite that of the elastic (10).
- the stitch sewing machine (MC) is in itself already known.
- US patents 5,014,634, US 5,272,993 and US 4020775 describe sewing machines spikes for stockings.
- the device in question can also be used for feed the shapes of a sewing machine tights of the so-called "line-closer" type already known to those skilled in the art.
- US patents 4444140, US 5345889 and US 4303026 describe sewing machines for tights.
- a transfer apparatus at all analogous to that described with reference to Figg. 2 and 3 and intended for invest manufactured products with elastic open to the forms of the line-closer machine at place only on the tubes (8) on mentioned.
- manufactured products treatable by the present device can be also manufactured tubular fabric products non-elastic and that in the case of stocking manipulation, the elastic portion intended at the opening can be either the one in body correspondence as illustrated in the Figg. 2 and 3 of the drawings, that of the tip of the foot.
