to.

In such, / DE-GBMS 72 13 450 known input device, the laundry item is manually clamped in the gripper with its corners, whereupon the gripper perform a movement away from each other and thus spread the laundry. In the expanded condition, the cross member is now moved in the conveying direction of the input conveyor, whereafter the grippers are opened and the laundry item released over the input conveyor in a certain partial area is released, whose leading edge drops onto the input conveyor. During the collection of the laundry item, the cross member returns to its original position and can be charged with another piece of laundry.

When releasing and falling of the leading laundry edge, the laundry is temporarily left to itself. It may therefore easily happen that the leading edge overturns or the item of laundry shifts on the input conveyor , so that no correct angle insertion of the laundry item in the defect or the like. becomes possible. Quite apart from the considerable design effort is also not ensured that the laundry can be introduced exactly in the middle of the defect, which is particularly important when connected to the defect folding devices.

J & 2-el the invention;

The invention has for its object to simplify the clamping and spreading of the laundry, to achieve a choice of exactly centered or laterally offset input of the laundry and voifallem the transfer of WäschestOckes on the Eingangseforderer to improve so that a right-angled or edge-appropriate introduction of Garment is guaranteed in the defect or other laundry treatment machine

 the essence of the invention:

To solve the problem, the invention of the above-mentioned prior art document and proposes that the cross member is rotatably mounted about its longitudinal axis and a motor pivoting about a specific pivot angle coupling and that the upper part of the two mutually fe¬dernden clamping plates existing gripper over is the lower part hinausr _a GT and provided with a parallel to the transverse support axis extending roll, the free edge of the lower part a non-touching the input conveyor pivoting, on the other hand the role of a plane of the input conveyor (thought) describes penetrating pivoting.

With such a type of input device, a particularly simplified movement during insertion of the laundry into a deficiency o.dgi. be brought, which provides the security, the laundry piece kanten_gerecht and to introduce at the choice centered or off-center. This advantage is related to the fact that the gripping arrangement according to the invention does not store the laundry item on the input

can drop off conveyor but this, input conveyor forcibly in the desired position passes, so that the known input devices alleged deficiencies can not eintre th. Characterized in that the roller connected to the upper part of the gripper describes a pivoting path, which is thought to pass through the plane of the input conveyor, it is achieved that the roll during the pivotal movement of the cross member, the leading edge portion of the laundry article during this begins to release from the gripper , presses against the input conveyor and, to a certain extent, eliminates it. Since the upper part of the gripper, on which the roller is arranged, is arranged resiliently and pivotably with respect to the lower part, the roller does not actually penetrate the plane of the input conveyor but is guided along this plane under springing pressure, which at the same time has the consequence that the clamped Wäschestückbereich fei is. Because by the impact of the roller on the input conveyor automatic opening of the gripper, during the pivotal movement of the cross member by the pivotally mounted upper part - away from the action of a spring force from the rigid base, which during the pivotal movement of the cross member is not in contact with the Input conveyor arrives.

In this way, it can also be ensured that the opening of the gripper, which begins when the laundry item is placed on the input conveyor, remains locked until the gripper returns to the position for

21 3 264

the application of the next piece of laundry has returned.

The solution possibilities suitable for this purpose can be taken from the subclaims, for example.

It is now possible to arrange only one pair of grippers on the cross member according to the invention, which results in the cross member having to rotate 360 during an input movement. But it is also possible, at the Que

rträger two gripper pairs opposite to arrange,

so that the cross member only needs to be swiveled by 180 "

The invention further relates to an arrangement according to the subclaims and the described embodiment, which ensures that the gripper or the like via simple gear arrangements either in a precisely central location to the defect. or · can be placed in an off-center position.

Finally, the object of the invention is a simple arrangement which makes it possible to carry out the movements of the individual grippers moving toward or away from one another, wherein it is advisable to carry out the individual gripper movements in opposite directions, for example such that the grippers located on the operating side allow the gripper to spread out clamped laundry items move away from each other while the opposite gripper, already the laundry item

handed over to each other.

The object of the invention will become apparent from the claims, the description and the drawings, even if features shown in the drawing are not expressly mentioned in the description.

8 and 9. In the embodiment of FIGS. 1 and 2, the basic arrangement of the input device according to the invention is shown.

At a distance above an input conveyor Π is cross member 1 rotatably disposed about its longitudinal axis. On this cross member 1 gripper pairs 2 and optionally 3 are guided displaceably along the longitudinal axis. The cross member 1 is, in contrast to m state of the art, not moved transversely to its axis. The pivot drive of the cross member 1 is carried out by a motor which acts on gears 5,6 and a chain 7 on the axis of the cross member 1 »On this axis is also a disc 8, which is provided with recesses, which are tapped by locking elements 9 become. These locking elements 9 have the property of a coupling. As soon as the latching element 9 engages in a recess of the disk 8, the rotary drive of the motor 4 is blocked. If only one gripper pair 2 is arranged on the cross member 1, the Getaebeanordnung 8.9 acts as a toe clutch. However, are, as Figs. 1 and show the cross member 1, two opposing pairs of grippers provided 2.3, then, the disk has 8 two opposing recesses, so that a completion of the pivoting movement takes place after IBO degree of rotational movement of the cross member 1.

The functioning input device is shown in Figs

constructive embodiment of a single gripper shown in Fig. 6 in perspective, with 12 schematically a defect

and TO are the laundry item.

According to Fig. 3, the leading edge of the laundry item 1 between the upper part 14 and lower part 13 of the single gripper (see Fig .. 6) is arranged, wherein in Figs. 2 to 5 of the gripper is shown schematically with 2 and 3 respectively. The cross member 1 is now rotated from the representation shown in Fig. 3 about its pivot axis 33 in the clockwise direction, so that the gripper assembly 2 approaches the input conveyor 11.

In the intermediate position shown in Fig. 4, a roller 15 located on the upper part 14 of the gripper 2 has approached the input conveyor so far that this roller 15 begins to press the laundry article 10 against the input conveyor 11. The lower part 13 of the gripper 2 does not come into contact with the input conveyor 11 during the pivotal movement of the cross member 1.

Upon impact of the roller 15 on the input conveyor 11, the upper part 14 of the gripper 2 is pivoted about the pivot axis 34 in the counterclockwise direction and against the action of a spring 16. As a result, upper part 14 and lower part 13 separate from each other, resulting in the release of the leading, previously clamped © edge of the laundry article

21.3 2 64

leads. This position is shown in Fig. 5. In the further course of the pivoting movement of the cross member 1, the roller 15 now deletes the free-coming edge of the laundry item on the input conveyor 11 and forms with the input conveyor a pair of clamping rollers, which the secure collection of the laundry item 10 in the defect 12 o.dgl. brought about, without the leading, free-coming edge of the laundry item 10 is moved or turned over gaif.

In the further course of the pivoting movement of the cross member 1 then the Greiferpdar 2 comes away from the input conveyor 11, while the gripper pair 3 enters a receiving station for the entrapment of a new laundry item.

To accomplish this function of the gripper according to the invention, some conditions must be met. As has already been mentioned previously, the lower part 13 of the gripper 2 or 3 shown in FIG. 6 must have a dimension which allows the free edge of the lower part 13 not to come into contact with the input conveyors, if at all. This lower part 13 of the gripper 2,3 is rigid in the design game, It has a clamping plate 35 which is rounded or bevelled at its free edge, so that no edges can exert adverse effects on the trapped * garment 10.

The upper part 14 of the gripper 2,3 is fixed in the pivot axis 34 ^

3 2

Lower part 13 rotatably mounted and loaded with a spring 16 whose spring force is directed so that the two gripper parts 13,14 are normally clamped against each other. At the free edge of the upper part 14 is a rotatably mounted roller 15, the axis of which extends parallel to the pivot axis 33 of the cross member 1. This roller 15 projects beyond the free edge of the lower part 13 and its clamping plate 35 also. The distance of the roller 15 from the Schwenkachee

, Schwenkbewegun g of, 33 of the cross member 1 is dimensioned so that during a ^ cross member, the roller 15 would theoretically hfndurch run through the upper run of the input conveyor 17. However, since the upper part 14 are pivotally and resiliently mounted with the roller 15, the roller 15 along the upper run of the input conveyor 11 along, whereby, as already said, a pivoting movement of the upper part 13 in the counterclockwise direction about the 'axis 34 results.

This pivotal movement of the upper part 14 can now be exploited to ^! to lock the forming opening point of the parts 13,14 of the gripper 2,3 as shown in FIG. 5 in the further course of movement of the cross member 1. For this purpose, a lock is arranged on the underside of the upper part 14, which is directed against the lower part 13 and the clamping plate 35. At this clamping plate 35 is a leaf spring 18 with cam or counter-stop 32, against which the lock 17 acts during the pivoting movement. In this case, the lock 17 skips the stopper 32 and engages against the leaf spring 18, so that in this, in Fig.6

Directed motion sequence, the opening position of the parts 13,14 is locked. In this position shown in Fig. 6, the single gripper returns to the operating station. If you want to pinch a laundry item 10 in the gripper 2,3, you need only slightly depress the leaf spring 18. As a result, the lock 17 is released from the leaf spring 18, which causes the upper part 14 is depressed under the action of the spring 16 against the lower part 13,35 and clamps the garment 10. FIG. 6 further shows that the individual gripper 2, 3 is movably guided along a running rail 20, which forms part of the cross member 1, which is shown in greater detail in FIG. The lateral movement of the gripper 2,3 is brought about by a cable 21, which is jammed with the lower part 13 of the gripper 2,3. This lower part 13 is also connected by means of angles 19 to the guiding members within the running rail 20. ,

In the examples of Figs. 7 and 8 will now be shown how the individual gripper 2 can be adjusted from a laterally offset position by simple means in a central position, based on the insertion level of the defect. The cable 21 (see Fig. 6) is guided circumferentially and endlessly within the cross member 1. At the upper run of the cable 21 of a gripper, attached to the lower run of the cable 21 of the other gripper. The cable 21 is

over pulleys 24, 25,26,27 endlessly guided. The deflection roller 24 is connected to a lifting motor 29 and guided along the longitudinal axis of the cross member 1 movable. The two pulleys 25,27 are stored stationary, whereas the Umlerikrolle 26 in turn guided movably in the longitudinal direction of the cross member 1 and is loaded by a spring 28. ,

It is assumed that the two grippers 2 in their initial position

Take 3 eccentric position, the one gripper the

Distance y and ^{1 of} the other grippers have the distance χ to the central axis of the input device. This eccentric starting position of the gripper 2 is recommended because it is often necessary or expedient, the laundry items off-center in the shortage or the like. which is especially true for small parts. Are two gripper pairs arranged opposite each other on the cross member 1, then a mirror image off-center basic position of the gripper 2,3, especially for the operation of the entire arrangement by two is recommended

To induce people in an alternating rhythm, whereby it can be assumed that one person positions himself at the left and the other person at the right entry point.

However, an advantageous for the practice input device must also have the opportunity to introduce laundry items exactly in the middle of the defect. For this purpose, the lifting motor 29 is provided, which is able to

the deflection roller 24 by the amount -r- * to put. This displacement movement obtains a reaction on the guide roller 26, which due to the tightening of the cable 21 from the position according to FIG. 7 goes into the position shown in FIG. 8 and thereby biases the spring 28. By this action on the cable 21, which takes place according to the principles of a pulley, the individual grippers 2 are set at the same distance χ {relative to the central longitudinal axis of the input device). In the recognizable in Fig. 8 position is now ensured that an insertable into the gripper 2 piece of laundry can actually be introduced exactly in the middle of the defect.

FIG. 9 shows the mirror-inverted basic position of the grippers 2, 3 relative to the central longitudinal axis of the input device.

When clamping the laundry item in the gripper 2, these grippers 2 are in a highly approximate position. The laundry must therefore be spread out before it can be transferred to the input conveyor 11. For this purpose J.st now in each cable 21 a Kubmoior 22 arranged, the cylinder is preferably held stationary, whereas the piston rod 23 is fixedly connected to the upper run of the cable 21. If one now moves the piston 23 with respect to the lifting motor 22 by means of a suitable hydraulic or pneumatic medium, the movement takes place according to the direction of advance of the piston 23

an Annah_erungs- or distancing movement of the individual gripper 2. In the latter case, the laundry, which is clamped in the grippers 2, spread. In the expanded state now acts a frictional force between the grippers 2,3 and the laundry item 10, the size of which can be used as a control means to end the lifting movement of the lifting cylinder 22. As a result of switching the rotational movement of the cross member 1 can now be set in motion.

If now, as shown in FIG. 9, two gripper pairs 2, 3 are arranged on two opposite sides of the cross member 1, it is recommended

it is to control the lifting motors 22, 30 in opposite directions, namely, that on the input side, the grippers 2 are moved apart, while on the opposite side, the grippers 3 are approached each other and vice versa. In this way it is achieved that an approach of the opposite gripper takes place during the spreading of the laundry article to be inserted, which thus occupy a position upon arrival in the input position, which makes it possible to clamp the next laundry item comfortably in the gripper. For this purpose, it is only necessary, the lifting motors 22,30, based on the pivot axis 33 of the cross member 1 diagonally opposite an_zuordnen, as can be seen from Fig. 10. It will be

With the piston rod 37 of the otherwise Hubmotores 36, the two Umlenkroilen 41, 42 are connected, via which the cable 21 is guided. The one cable end is attached via a spring 37 on the lifting motor 38 / the other end of the rope is clamped orstfest. A displacement of the deflection roller 41. to the left has a direction indicated by arrows movement of the cable 21 result, causing the gripper pair 2 moved apart and the gripper pair 3 approaches each other. In this case, one gripper of the gripper pairs are 2.3 at the upper run, the other gripper of the gripper pairs 2.3 cm lower run of the cable 21 attached, the wfederum: on the pulleys 39, 40 is guided.
