Description

Field of application of the invention

The invention relates to a device for folding for textile Flechengebilde, said belonging to this device folding flap has a flat Auflaufstellung and a steeper waste position for the textile Gefächengebilde.

Characteristic of the known technical solutions

It is already a Abwäizfaltvorrichtung for items of laundry known (DE-GM 7 317 606; D 06 f, 89/00), in which the folding flap device in a slipping off the initial edge of the laundry piece when releasing the clamping favoring steeper position. This is achieved in that the folding flap as one in a Kipphebe! pivotally arranged ramp surface is formed, which is held by a tilting lever arranged on the torsion spring in a flat Auflaufstellung. When swinging the folding flap, the laundry between the front edge of the clamping plate and a stop is clamped. The further upward movement of the rocker arm causes the rear edge of the clamping plate abuts against another stop. As a result, the angle of the clamping plate is increased to the rocker arm, so that engages actuated by a torsion spring pawl under opposite to the beginning edge of the laundry item detecting side of the ramp surface.

When lowering the rocker arm causes the actuated pawl, that the clamping plate is brought into a steeper position and thus a slight slipping of the laundry item is accessible from the clamping plate. After another piece of laundry to be folded presses a button, the Kipphebe! further lowered down, so that the ramp surface slides past the pawl and is brought by the tilting lever arranged on the torsion spring in the laundry upright position.

However, this device has the disadvantage that the fixedly arranged bearings of the rocker arm and the pivotable ramp surface requires a relatively large distance of the folding bridge to the conveyor belts and at the same time requires a non-variable angle of contact.

Another disadvantage is also to be seen in the fact that can not be excluded by the stationary stop, which serves to clamp the laundry, when pivoting the clamping plate in a steeper position a delay of the laundry item, which inevitably leads to a non-quality folding.

On the other hand, the device has a plurality of stops and actuated by Torsionsiedern pawls and clamping plates. However, these components hardly allow a largely quiet operation of the folding device.

Furthermore, by dia variety of parts that are necessary to achieve the steeper position of the clamping plate, a relatively high effort in the production and maintenance required.

Object of the invention

The aim of the invention is to form the device for folding so that a delay of the beginning edge of the laundry item when pivoting the folding flap is avoided in a steeper position. The aim of the invention is also to achieve a reduction in the number of parts and thus the associated cost of manufacturing and maintenance and a largely quiet operation and, if necessary, a change in the angle of attack of the folding flap.

Essence of the invention

In the known technical solution of the delay of the laundry item is due to the fact that the folding flap is pivoted in clamping position to the stop and thus there is a relative movement between the folding flap and the stop.

On the other hand, the present on the known device torsion springs when released a relatively fast movement of the pawl or clamping plate, so that despite existing attacks a noise of the folding device can not be completely excluded or requires considerable effort.

In order to avoid these disadvantages, the folding device according to the invention for textile fabrics has at least one folding flap arranged over a conveyor, at least one stop and at least one working cylinder, through which the folding flap moves from a position detecting the leading edge of the textile fabric into a leading edge between the two Stop and the folding flap clamped and then in a steeper, the sliding of the leading edge of the laundry favoring position is movable, the bearing of the folding flap including the folded flap, the folding flap actuated working cylinder and the stop are pivotally mounted about a common pivot point. This pivot point is formed as a mounted shaft to which the bearing of the folding flap by a connection and a receptacle for the working cylinder and the stop are rigidly mounted. The pivoting movement about the fulcrum is achieved by at least one working cylinder fixed to a folding bridge, the piston rod of which acts on a lever rigidly connected to the shaft. Conveniently, the working cylinders are designed as pneumatic cylinders.

When folding the laundry item, the starting edge of the textile fabric runs on the folding flap until the actuation of a switching element. By this operation, the working cylinder is subjected to compressed air and causes the pivoting of the folding flap, so that the starting edge of the laundry between the folding flap and the stop is clamped. After reaching this position, the loading of a likewise arranged at the fulcrum working cylinder takes place, wherein the extending piston rod, the pivotal movement of the stop, the working cylinder, the bearing of the folding flap and the folding flap carried out without loosening the clamping and thus the folding flap is pivoted to a stiffer position. If the end edge of the item of laundry passes a switching element provided for its scanning, the unwinding or opposing loading of the working cylinder required for the gripping and clamping of the starting edge of the textile fabric takes place. The beginning edge thus falls from the folding flap, so that the folding process is completed.

After the expiration of this folding process, arranged for the pivoting of the entire folding device working cylinder is relaxed or counteracted with compressed air, so that the folding device moves back to its starting position and in a the leading edge of the textile sheet detected position. By this solution, it is possible that the folding device operates with low noise and distortion of the leading edge of the textile fabric is avoided when pivoting the folding flap in a steeper position. On the other hand, a low overall height of the entire device is achieved.

embodiment

The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawing shows:

1 shows a schematic representation of the folding device in which the folding flap is in the laundry emergence position,

2: schematic representation of the folding device, wherein the laundry item is clamped between the folding flap and the stop,

3 shows a schematic representation of the folding device, wherein the folding flap assumes an angle of inclination to the conveying plane and

4 shows a schematic representation of the folding device, wherein the folding flap is in the laundry waste position.

The folding device is located above the conveyor belts 1 in a folding bridge 2, wherein the folding bridge 2 is fixed laterally by walls 3 fixed on the machine frame, not shown.

In the folding bridge 2 is a suspension 4 for a working cylinder 5. The piston rod 6 of Arbeitszyiinders 5 stands with a lever 7 in connection. This lever 7 is rigidly connected to a square shaft 8 which is rotatably mounted in the bearing 9. The bearing 9 is located at the bottom of the folding bridge. 2

On the square shaft 8, another lever 10 is rigidly fixed, which serves as a suspension for the working cylinder 11. Furthermore, located on the square shaft 8, a support arm 12 whose end is angled and this end has a bearing point 13. This bearing point 13 serves to receive a square shaft 14. At this square shaft 14 are once a lever 15 with a receiving pin 16 for the piston rod 17 of the working cylinder 11 and on the other hand, the folding flap 18 is arranged.

For secure clamping and holding the starting edge of the laundry item 19, the square shaft 8 has an elastic stop 20, which consists for example of a rubber profile. To trigger the folding operation, scanning elements 21, 22 for scanning the beginning and end edge of the respective item of laundry 19 are arranged in front of the folding bridge 2 and in the region of the folding flap 15.

In order to achieve a safe emergence of the leading edge of the laundry item 19 on the folding flap 18, 18 casserole 23 are arranged in the direction of movement of the conveyor belts 1 in front of the Fa'tklappe.

Furthermore, in front of and above and parallel to the front edge of the folding flap 18 is provided with a nozzle tube 24 which is fixed to the folding bridge 2.

Upon emergence of the laundry article 19 on the folding flap 18, the light beam of the scanning element 21 is interrupted and thus acted upon via a control device, not shown, of the working cylinder 11 with compressed air. As a result, the protruding piston rod 17 moves the lever 15, whereby the arranged on the square shaft 14 folding flap 18 pivots upward and the front edge of the laundry item 19 between the stopper 20 and the folding flap 18 is clamped.

Due to the continuous movement of the conveyor belt 1, the further movement of the laundry item 19 in the conveying direction, so that a fold is formed. To assist in this process, compressed air exits the nozzles of the tube 24, which blows into the forming wash fold. After the starting edge of the laundry item 19 has been clamped between the stop 20 and the folding flap, the loading of the working cylinder 5 is carried out with compressed air. This causes the extending piston rod 6, which is mounted on the lever 7, a rotation of the square shaft 8 and thus arranged on the square shaft 8 elements (lever 10, cylinder 11, support arm 12, square shaft 14, bearing point 13, lever 15th , Folding flap 18 and stop 20) causes. By this work cycle, the angle of the folding flap 18 to the conveyor belt 1 changes. The folding flap 18 now assumes a steeper position.

After the end edge of the laundry article to be folded 18 has released the light beam of the sensing element 22, the working cylinder 11 is relaxed or counteracted with compressed air, so that the folding flap 18 swings down and thus releases the beginning edge of the laundry article. It falls on the end edge of the laundry, so that the folding process is completed. About a delay member, not shown, the folding device is brought back into the laundry flow position, in which the working cylinder 5 is relaxed or counteracted with compressed air.

The control and regulating devices required for actuating the working cylinders 5, 11 have not been shown, with the exception of the scanning members 21, 22.
