Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cylindrical fabric, particularly a tights-like article (Co11ant).
), the openings of the cylindrical fabric are located at a distance from each other, and the internuclear [parts] are hung on a supporting hanger to maintain the open position; The present invention also relates to a device for transferring a cylindrical fabric to a rigid body adjacent to and in line with the hanger by inversion.

The device includes a slider that is longitudinally movable on a fixed guide member and pliers mounted on the slider. The device also includes four independent rotatable elements arranged in two pairs on two independent planes, and which protrudes in front of the slider and opposes the action of a spring to the slider. It includes a pan that can freely rotate axially. The plunger is supported by the plier element and can be extended for insertion into an opening in the cylindrical fabric as the slider moves forward. When the pliers are then unfolded, the cylindrical fabric is lifted from the support hanger.

The plier elements serve to place the cylindrical fabric onto the rigid body.

The pan then presses the joint of colant onto the hard object under the action of the spring, and when the plunger is retracted against the respective plier element, the tights are placed in an inverted position on the rigid object.

It is known that it is often necessary to transfer the cylindrical fabric from a supporting hanger onto another support object and to subsequently process the fabric further.

For example, in conventional equipment, a hanger is provided on which the cylindrical fabric containing the legs of the tights is manually hung over the two elements, allowing a series of modifications such as joining the cylindrical fabric to each other. It is well known that machines have been developed that can automatically carry out operations. Therefore,
At the exit of the machine, after the automatic sewing operation of the two legs of the tights-like object is completed, the finished tights-like object is in a state in which its opening is opened and hung on each pair of hangers. It is supported by a pair of rigid hangers that are part of the machine. A machine designed as described above is described, for example, in German Patent No. 2,432,941.

This machine is also automated and is equipped with a rigid cylinder or object. The first machine-made tights described are fitted manually. The tights are pressed or tightened by automated mechanical gripping members on each cylinder.

Therefore, a small reinforcing block or insertion piece is automatically applied to the inside of the tights (corresponding to the outer surface of each tights in this case) and automatically sewn onto the tights. A machine of such design is described in British Patent No. 2.001.238.

The tights produced by the automatic stitching machine are manually pulled out and automatically fed onto the machine's supporting cylinder, which attaches the block or insert, and is inverted. This has serious drawbacks.

The reason for this is that manual operation becomes very expensive and, moreover, the current high output speed required from machines is slow.

The first object of the invention is to provide an automated device. In this device, a cylindrical object (fabric) attached to a support (21) hanger is pulled out at a very high speed and then sent to another support object (21) by an operation of being reversed. The object is in sync with the hanger.

In particular, it is an object of the present invention that the tights-like article sewn by an automatic sewing machine are automatically pulled out and turned over on the cylinder, so that the tight-like article is placed on the supporting cylinder of the machine. The goal is to provide equipment that can be transferred. There is also a sleeve provided at the junction of tights.

A further object of the invention is to provide a device which is of very simple construction, easy to operate and designed to be easily adapted to the well-known machines currently in use.

A further object of the invention is achieved by means of a device for drawing out, inverting and transferring a cylindrical fabric supported by a support hanger onto a rigid body. The device comprises a slider adapted to be longitudinally movable on a fixed guide member. This ensures movement to and between the support hangers, and also movement to the free end of the rigid body and vice versa.

The device is mounted on the slider and is configured to be rotated by mechanical means between a position where the elements (plier elements) move closer to each other and a position where the elements are spread out. The pliers include at least four independent plier elements. Each plier element has a mandrel supported by it, and the position of the plier element remote from the support hanger for the cylindrical fabric and the llYJII body, ] The apparatus of the present invention is provided with a drive set for driving the slider in either direction between a close position acting on the end and a drive member for moving the plier element.

In order to more clearly understand the structure and characteristics of the device of the present invention, the present invention will be described below with reference to specific examples, but the present invention is not limited thereto.

In the accompanying drawings, FIG. 1 includes two interlocking parts and devices of a tights sewing machine and a machine for automatically attaching reinforcing blocks or inserts onto the tights. Figure 2 is an enlarged overall cross-sectional view of an assembly similar to the assembly shown in Figure 1 at a stage just before the start of work; Figures 3 and 4 are for suturing. Two overall cross-sectional views of the device showing the subsequent two steps of the operation for approaching the tights-like object hung on the hanger of the machine and the operation for processing the tights-like object, FIG. Figure 6 is a sectional view of the apparatus at the beginning of the operation of transferring the tights from the support hanger to the rigid cylinder and attaching the reinforcing blocks or inserts to the tights; Figure 2 is a cross-sectional view of the device in the final step of inverting the cylinder and attaching the block or insert inside the tight.

In Figure 1, part 1 is a tights-like item (col, 1-
is part of a machine of a known type for automatically sewing two cylindrical fabrics to make ant), and also the part forming the cylinder 2 of the machine with reinforcing blocks or inserts on the corant. This is of a known type for automatically applying and sewing.

The first machine described above includes two rigid metal hangers 3 onto which the opening of the tights is hung and pulled outward. The free end of the opening or waist of the tights is marked 4, while the leg of the tights is marked 5, and the intersection of the legs of the tights! 4rlshi;, 6 is attached. Two hangers 3 are placed over the first e)1+ opening 7, these hangers being movable relative to each other in a known manner. Two tubes 8 are provided below the end of the leg 1 (only one of the legs is shown). The two tubes are connected to a suction source to keep the free ends of the two legs 5 of each tights sucked downward, so that the entire tights are placed on the two hangers 3. held in tension.

The machine for sewing tights has a number of pairs of /'' trousers 3 arranged in the positions shown.

In front of the pair of hangers 3 is located the rigid body or cylinder 2 of an automatic machine, which is arranged to automatically sew blocks or inserts onto tights-like articles.

In each case, a transfer device according to the invention is arranged in line with the cylinder 2 and the pair of hangers 3, which device includes a rigid guide jolt comprising a metal beam 28.

A guide rod 9 extends from the beam.

The guide rod supporting the slider 10 is the beam 2
The piston rod 1 is movable within a hydraulic or hydraulic cylinder 12 supported by a piston rod 1 .

The slider is a pliers element 1 with 4 independent elements.
I support 3. The plier elements are fixed two-to-two to the two bins or parallel to the phase 77' and are supported by sliders, as shown in FIGS. 2-6.

Said plier element 13 is connected to the piston rod by a small connecting rod 14. The piston is movable in a pneumatic or hydraulic cylinder 5 which is supported by a slider 0.

The movement of the rod projecting from the cylinder 15 spreads the pliers or turns 11 of the plier element 13! J.
As a result, it is clear that the arrangement can be approached such that there are two on one plane and two on another plane parallel to the plane.

The distal portion of the pliers element 13 is hollow inside and receives the mandrel 16 therein (see Figures 3 to 6).
. The mandrel can be moved so as not to protrude beyond the 1-11 end of the element 13 (see Figures 1 and 2). (FIGS. 3 to 6).The protrusion or retraction movement of the mandrel within the element 13 can be carried out in a known manner.

For simplicity, barb springs (not shown) are shown in the accompanying drawings.
Contrary to the operation of the element November γrJ room 1j) 1
(The axles of four pistons are shown 41. The movement of the axles in the protruding direction is caused by supplying compressed air through the hose 17. (only two are shown).

Additionally, the device is shown with a pan 18 integral with a mandrel 19 that slides and moves freely in a suitable seat, with a pan 18 moving between the pan and the slider and wrapped around one mandrel. It includes a spring 20 that pushes the pan to the right.

Assuming that the apparatus is now in the state shown in FIGS. 1 and 2, the apparatus is either stopped or activated, and a pair of rigid hangers 3 are located coaxially at the front of the apparatus. The hanger is part of a machine for sewing tights, and the cylinder 2 of the machine is used to automatically sew blocks or inserts onto the tights. As shown in FIG. 1, the two hangers 3 are spread out from each other, and the opening of the tights is kept open. Part 1 above has been omitted in FIG. 2 for simplicity. Therefore,
When the device is activated, compressed air is supplied to the fluid cylinder from the conditions of FIGS. 1 and 2, thus causing the slider 10 to move to the right along with all elements held by the cylinder. During the first phase of the movement of the slider 10, the pan 18 enters the opening of the tights (FIG. 3), while the free end of the rigid pliers element 13 approaches the end 4 of the tights. move to.

During this first stage of movement, the device is subjected to a movement or control that causes the mandrel 16 to protrude from the respective seat of the member 13 as shown in FIG.

The slider continues to tighten to the right, the main stick is 16.
enters the inside of the tights-like object from the outside of the end 4 of the opening 11. On the other hand, the bread 18 moves adjacent to and in contact with the junction 6 of the tights-like article (FIG. 4).

As the slider continues to move, the pan 18 moves the abutment 6 of the tights along the free end 2'' of the cylinder 2'': A: so that it is in line with the free end of the cylinder. 5, the mandrel protrudes, and the rigid pliers element 13 is expanded as shown in FIG. Therefore, it is not shown in Figures 5 and 6).Now,
When the slider continues to move to the right, the tights are lifted and pulled out from the pair of hangers that were previously held, and the tights are opened as shown in the figure. It is carried into the cylinder 2 and finally the junction 6 of the tights is pressed by the pan 18 onto its own 111 end of the cylinder. Tights-like! It rises and falls on the opposite cylinder, and is also reversed.

The mandrel 16 is now re-accommodated within each seat of the rigid assembly 13. The tights-like end 4 is pushed forward. The waist portion and free end of the tights therefore fall from the position of the hanger 3 in an inverted state into the cylinder 2''. The device is changed from said position to the rest or operating position shown in FIGS. 1 and 2 by a reverse movement.

As soon as the inverted tights are placed on the cylinder 2, the forming part of the machine jaws 20 is automatically pressed against the cylinder. The machine is designed to automatically apply and sew reinforcing blocks or inserts at the junction of tights.

From the above description, the operation of the device is fully automated and has a very high working speed.

On the other hand, conventional methods required a lot of manpower and a long period of time.

If it is possible to achieve the same purpose and function as that achieved by the automatic device for inverting cylindrical fabrics as described in the attached drawings, It is clear that a) can also be used in anisotropic manner as a member for regulating the movement of the movable parts of the device.

As explained above and as shown in the drawings, although the device is fully functional and suitable for achieving the desired purpose, some parts of the device are It must be pointed out that Masatomo can be done without departing from the scope of the invention. For example, instead of the mandrel 16 being able to be mounted on each plier element 13'', the mandrel 16 can be fixed onto the plier element. On the other hand, the pan 18 with the mandrel 19 and spring 20 does not have to be mounted. In addition, the device can efficiently transfer the cylindrical fabric onto a hard object (cylinder) and invert it in this case as well.

Finally, in the specific example illustratively shown above,
A case is described in which the mandrel 16 is inserted into the opening I-1 of the sea urchin strike of a tights-like object, but β140 where the mandrel is inserted is
The part may be a part other than the waist of the tights-like article, for example, an opening at the junction of the tights-like article. It is important to note that in this case the reinforcing blocks or inserts must be sewn on after the tights have been transferred onto the rigid object 2 and turned over.
