Device for the fully automatic laying and folding of elongated textile goods, such as stockings, tights, etc.

The invention relates to a device for laying and folding elongated

shaped textile goods, such as women’s tights, stockings and

together with a winding card and, if necessary, a plug-in card

The known devices for semi-automatic or automatic folding of long-shaped textile goods to be packaged, for example women's tights, pantyhose and stockings and the like, have a large number of work steps that do not meet today's requirements. The folding and laying of the machines known to date takes place too slowly.

The advantage of the device according to the invention over previously known devices is that this machine works faster and more efficiently. The further advantage is that it works more variably than previous ones. This is due, among other things, to the variably adjustable photocells and also to the ability to convert the rake. By simply moving this rake, you can switch from right folding to left folding. The electronic speed control of the folding belts is also advantageous. This is necessary because the different types of stockings (types of fabric) in conjunction with the winding card prevent them from slipping. This is controlled by the electronic control. Correspondingly, it is also advantageous to reduce or increase the number of cycles for the types of stockings to be laid or packaged.

After production, hosiery, e.g. women's tights, stockings and the like, are picked up by a correspondingly aligned device that dries the stockings and checks them for material and color defects. If the tights prove to be satisfactory, they are transferred via a conveyor device to the device according to the invention, which is arranged on one level and at the same height in four stations, which causes the corresponding types of stockings and the like to be inserted fully automatically.

This object is achieved according to the invention in that the stocking...

trousers, socks and the like from the conveyor belt of the drying and inspection device with the foot shape in the working direction coming from the····

The first folding belt, which is a continuous, all-round belt that is advantageously coated with silicone, is picked up. The picking up takes place via a photocell, which, in conjunction with the control program and the corresponding electric motor, transports the elongated textile product via folding belt 1 to the all-round folding belt 2, which is also located at the same level and height (Figure 1 schematic drawing). Slipping or warping is prevented according to the invention by the uniform speed of the two all-round belts and the applied silicone coating. Depending on the length of the textile product, the process of taking it over or applying it to the first two folding belts is controlled electronically.

In a certain position of the tights after reaching the second folding belt, which is caused by the upstream light barrier, folding belts (2) and (3) are pneumatically raised and also pneumatically opened (Figure 2 schematic drawing).

In this position, the electronic control lowers the wrapping card with the wrapping card laying arm onto the end of the first folding belt. At the same time, the running direction of the second folding belt changes to the left, thus causing the card to be pulled in.

of the tights between folding bands (2) and (3), so that the stocking* is now folded in the first third onto the folding band (4) with the eight endlessly circulating and silicone-coated bands!"*" (Figure 4 schematic drawing). **

Two adjustable photocells are integrated into the folding belt (4) which determine the positioning of the elongated textile goods. Using a folding rake at the beginning of the folding belt (4), the thickened end of the tights is inserted by folding it to the right (Figure 5 schematic drawing).

When the second folding rack is reached, the tights are folded to the right again (Figure 6 schematic drawing).

The last right fold is made at folding rake 3, so that the stocking is now finally folded (Figure 7 schematic drawing).

By adjusting the folding rake three by 180° according to the invention, a left-hand fold is achieved in the last laying process (Figure 8 schematic drawing). This has the advantage that when packing the tights and the like in a transparent bag, the color impression and the quality are visible from the outside through the only double layer of fabric, while with the right-hand fold, an equally desirable, stronger color tone is visible. Furthermore, this results in

inventive implementation of the folding rake (58) the possibility of a*····

Light window insert.

The elongated and inserted textile goods are transferred to the last belt, J^, _the conveyor belt, which is arranged at the same height and level. The function of this conveyor belt according to the invention is that the incoming stocking can be electronically controlled to both slow down and accelerate. This depends on the weight of the folded stocking. This conveyor belt has the further task of transferring the folded textile goods to the packaging belt.

The invention is described below in drawings, wherein further advantageous details can be taken from the drawings.

The drawings show in detail:

The folding system consists of two folding stations (5) and (46) and a conveyor belt (61).

The first folding station (5) consists of three folding belts (1-3) whose transport belts are closed and endless all the way around. The second folding station (46) consists of the folding belt (4) and the transport belt (61).

The conveyor belts of the folding belts are inventive on the surface;··

with a silicone coating. This advantageous feature

design means that the load on the conveyor belt(s) to *·

The stocking being transported does not slip and is thus positioned. The stocking cannot get pulled between the folding bands and no creases are created. The stocking is smoothly taken over by the folding band (4).

The all-round closed transport belts of the folding belts (1-3) are fixed to the drive and deflection rollers (6) by a specific system in such a way that they are prevented from running off. For this purpose, there is a web (7) on the underside of the transport belts, which runs in a groove (8) of the drive and deflection rollers (6) of the folding belts (1-3).

The folding belts (1) and (2), which are arranged one behind the other at the same height and level, initially run in the same direction, and the stocking is transported towards the folding belt (2) by the circular movement of the folding belt (1). According to the invention, the elongated

Textile goods are moved into the intended position according to the upstream light barrier (9). After inserting the wrapping card··*· (10), the folding belt (2) runs in the opposite direction, namely to the left and pulls the stocking with the wrapping card* (10) lying on it between it and the folding belt (3). By pulling in **.

Between the folding tape (2) and the folding tape (3) the stocking is folded over the* wrapping card sheet for the first time. The length of this first fold can be varied.

When the stump with the wrapping card resting on it is positioned on belts (1) and (2), the conveyor belts (2) and (3) are each raised on axially mounted shafts (6a) by means of a pneumatic system, cylinder (11), the upper belt (2) is opened in conjunction with two other smaller pneumatic cylinders (12) attached to the folding belt (3) so that the stocking with the wrapping card can be inserted. After the wrapping card or plug-in card and stocking have been inserted, the two folding belts (2) and (3) close pneumatically again and the stocking with the wrapping card is ejected from the folding belts (2) and (3) in the appropriately folded form. The stocking and the like is now folded in a third over the wrapping card in the direction of the adjacent folding belt (4) (Figure 1-4 schematic drawing).

The pneumatic cylinder (11) according to the invention causes the pneumatic lifting of the belts (2) and (3) via a ball joint (13)

ball joint bearing connected to a shaft (14), as well as a Zu;···

!Air line (15) for the cylinder (11). _; *

Folding belt (1) is driven by a small electric motor (16).*"·* The axially mounted motor (16) is connected to a** * chain wheel (18) via the shaft (17). This chain wheel (18) is connected to a smaller chain wheel (20) via a chain _# (19). This rotating chain (19) drives folding belt (1) via the motor (16).

The folding belts (2) and (3) are driven by a small electric motor (21) by means of sprockets (22) and chains (23). On the drive axle (6) there is a toothed belt drive (24) which drives a second axle (25). On the opposite side of the second axle (25) there is a spur gear (26). This meshes with a second spur gear (27) on the drive axle (6) of the conveyor belt (2) and thus drives belt (2) via the connection according to the invention.

In a preferred embodiment, a winding card laying station (28) is provided. This winding card laying station (28) consists of the winding card magazine (15) and the winding card laying arm (29), the function of which according to the invention is achieved by the cylinder (30) of the laying arm (29) moving forward and removing the winding card (10) from the magazine (15) by means of four suction cups (32). Four hoses (33) are connected to the four suction cups (32) via supply lines, which in turn correspond to a vacuum pump (34). This vacuum pump

(34) causes the acceptance of the winding card via the four suction cups (32),

(10). The laying arm (29) with the suctioned winding card (10) moves ·

in a horizontal direction towards the coated conveyor belt (1J···· of the first folding belt and the stocking (31) positioned there in a horizontal·**· direction (Figure 1-3 schematic drawing). :

The drive (35) of the wrapping card laying arm (29) is located on a holder (36). On this holder (36) there is a rotary cylinder drive (35) with initiators (37). These electrical contacts control the position of the rotary cylinder. The rotary cylinder (35) is supported by spring force (2 tension springs) (38), which overcomes the inertia of the cylinder. The force of the rotary cylinder (35) is transmitted to the laying arm (29) via a toothed belt (39). The appropriate swivel angle is achieved by translating the two toothed belt rollers (40). When the laying arm (29) is swiveled down, the two conveyor belts (2) and (3) open. The entire laying arm mechanism moves towards the folding belts (2) and (3) by means of a second cylinder (41) and thus pushes the wrapping card (10) between the first two rollers of the folding belts (2) and (3). In this position, the suction process is terminated and the wrapping card (10) is released. Due to the material of the textile goods, the stocking, etc., as well as the type and thickness of the cardboard from which the wrapping card is made, it tends to spring back again after the suction process has ended. A

The retaining plate (42) holds the winding card (10) in position under the pressure of a tension spring (43) and thus prevents it from jumping back!*"

the same. After inserting the wrapping card (10) and the stocking (31), the folding bands (2) and (3) close. From this position ¹ .·.· the folding bands (2) and (3) start again and pull the stocking with··*·

of the winding card by the conveyor belts (2) and (3). The winding card (10) and the stocking (31) are transported by the movement of the preceding Baader on belt (4). This completes the first folding of the elongated textile product.

The thickened end of the elongated textile goods, such as women's tights, pantyhose, etc., requires a further step according to the invention, namely that when the stocking (31) is pulled in with the winding card (10) after the previous pulling-in process, the folding bands (2) and (3) open again briefly in order to reduce the strong pressure on the first two waves (5) of the folding bands. The pressure reduction is necessary because the elastic at the end of the stocking forms a thickening. This thickening causes an improper folding when the band is permanently closed and the upper folding band (2) to hit when the elastic passes this point. After this process, the folding bands (2) and (3) close again. The brief opening and closing is caused by the electronic control program (44), which works with the tension springs (45) and the two pneumatically operating cylinders firmly connected to the band (3).

(12) interacts.

The elongated textile, such as women's tights and the like, is now transferred to the folding belt (4) by the all-round folding belts (2) and (3). The folding belt (4) has eight individual conveyor belts (47) running all the way around, which are also coated with silicone on the surface. The centering of each individual conveyor belt (47) is carried out on the drive or deflection roller, which each have eight elevations (48) and thereby prevent the conveyor belts (47) from running off. The folding belt (4) has two speed levels. Below the conveyor belts in the middle of each of them are two photo switches (49) and (50) which regulate these speeds and are connected to the electronic program (44).

The stocking arrives at the beginning of the folding belt (4) at a higher speed and is controlled to a lower speed by the first photocell (49). This is intended to prevent the stocking from slipping with the winding card (10) and to ensure the exact positioning of the stocking. This is variable. Depending on the length of the elongated textile goods, the light barriers (49) and (50) are adjusted manually by moving them. The first light barrier (49) causes the stocking to stop, the second light barrier (50) ends the transport of the stocking on this conveyor belt (4) at exactly this point.

The conveyor belt (4) is driven by a small electric motor (51).

This axially mounted motor (51) is connected to the shaft (52)....

with a chain wheel (53). This chain wheel (53) is connected to,·***

a chain (54) is connected to a smaller sprocket (55). This ·

Circulating chain drives folding belt (4) via motor (51). *.···

In the laying and folding device according to the invention, the folding:

rake (56), which is generally present in the device or can be installed there later, is used for oversized stockings. Folding rake (56) has the function of first folding the trouser part (Figure 5 schematic drawing). Folding rake (57) folds the trouser part again (Figure 6 schematic drawing). If there are no oversized stockings, the folding rake (56) takes over the function of folding rake (57). The folding rake (58) takes over the final folding by swinging upwards like the two previous rakes and thus completing the last fold (Figure 7 schematic drawing).

This system can be varied by rebuilding the folding rake (58) so that it is axially mounted in the same place, i.e. it is now offset by 180° on the opposite side and now folds the stocking in the left fold (Figure 8 schematic drawing). In the first position, the folding rake

(58) the right folding. The preferred design of the respective folding direction is based on the needs of the user.

At the point where the axis of the folding rake (58) is located,

a pin (59) is attached which is extended pneumatically (60) _;

to prevent the winding card (10) and the stocking (31) from moving. The pin (59) is in the extended position at right angles and parallel directly above the eight transport belts (47). The pin (59) moves vertically up and down depending on the cycle of the folding belt. These movements of the pin (59) are also achieved with the electronic control program (44).

The movements of the pin (59) are necessary to initially hold the stocking and the wrapping card together in this position and then release them again.

The folding described on the folding bands (1-3) and (4) also works without inserting the wrapping card (10). In this case, instead of the wrapping card, a plug-in card pushes the stocking (Figure 3a schematic drawing) between the folding bands (2) and (3). The further folding is carried out as shown in (Figures 4-8 schematic drawing). This procedure is chosen when folding without a wrapping card (10) is desired.

A conveyor belt (61) is arranged at the same height as the folding belt (4). This also consists of eight circumferential and silicone-coated conveyor belts (62) and has the function of both braking and accelerating the incoming stocking. This depends on the weight of the folded stocking. The regulation of this

The conveyor belt (61) is driven by an adjustable direct current motor (63). The centering (64) of the eight conveyor belts on the acceleration or braking belt (61) is carried out in the same way as with the folding belt (4). In the transition from the folding belt (4) to the conveyor belt (61) and at the end of the conveyor belt (61) there are seven stripping or overrunning fingers (55) arranged _between the eight conveyor belts (62). Their arrangement and bending (Figure 19) prevent parts of a stocking from being pulled between _the drive or deflection rollers (66) by the grip of the conveyor belts (62) and destroying the stocking. At this point the elongated textile product is folded fully automatically and can be packaged.
