Description

The invention relates to a device on a card for filling a round can with sliver, for. B. cotton, man-made fibers or the like, in which the sliver can be dispensed from a rotatable depositing head and deposited in rings in the round can, during the filling process the depositing head is arranged above the round can and the round can is fixed on a rotatable can plate around a vertical one Axis rotates, and in the case of filling a full can and before filling an empty can, the local assignment between the storage head on the one hand and the full can and the empty can on the other changes (can change), and a full can can be removed and an empty can can be fed (can replacement).

1. 1. Leer- oder Reserve-Position
2. 2. Füllposition
3. 3. Vollkannenposition

Rotation can changers are used to change round cans on a card ( US 4208768 ) and linear can changer ( EP 967169 B ) known. These can changers are basically designed so that at least three possible can positions are available:

1. 1. Empty or reserve position
2. 2. Filling position
3. 3. Full can position

When changing cans, the round cans are moved and change positions. To do this, the depositing speed must generally be reduced, since otherwise fiber material is conveyed between the round cans. From the customer's point of view, however, a quick change of the round cans is desirable, so that the production of the card does not have to be significantly reduced. Furthermore, in the case of major changes, the Delivery speed fluctuations in the belt weight, which can negatively influence the technological result right down to the end product. A quick change of the round cans is associated with various difficulties. The round cans do not have a consistently stable structure and can therefore be damaged by high forces. On the other hand, the round cans differ from customer to customer, which makes the adaptation of recordings difficult. Furthermore, when filled, the round cans have a high weight, which causes high forces during short changeover times during acceleration.

In the known devices, the turntable (storage head) remains permanently stationary. The round cans are moved below the turntable, with the rotary can changer on a semicircular path and with the linear can changer on a straight line. With the help of the can changer, an empty round can provided in a reserve position for filling with sliver can be brought into a filling position below the turntable and, after filling, a round can filled with sliver can be brought into a discharge position from the filling position below the turntable.

In the US 2,571,880 describes a can changer with a swiveling storage head over two fixed but rotatable can plates. When changing the jug, the depositing head swivels from the full to the empty jug, with the pivoting movement simultaneously pivoting a drive element below the can plate.

The invention is therefore based on the object to provide a device of the type described above, which avoids the disadvantages mentioned, in particular when changing the can, ie when changing the local assignment between the storage head on the one hand and a full can and an empty can on the other, a movement of the round cans avoids, the time required to change the can can be shortened and the can plate drive can be easily implemented.

This object is achieved by the characterizing features of claim 1.

The fact that the storage head can be moved from a full can to an empty can to be replaced, preferably moved, and that the full can can be removed and a new empty can be fed in while an empty can is being filled, and the new can can be fed, the possible can positions are reduced from three positions to two positions . According to the invention, the round cans are no longer - as in the known devices - under the storage head, but the storage head is moved over the round cans. In contrast to the known displacement of the round cans, the displacement of the depositing head achieves high accelerations of the depositing head and thus short changeover times. In particular, the full cans can only be moved with high forces and not in a short time in the known devices because of their high weight. The operator removes the full cans and replaces them with an empty can, so that only two can positions have to be kept. The space requirement of the device according to the invention is significantly less than that of the known devices. In particular with regard to steadily increasing card production, an increase in the can diameter can be expected, which is then possible with the device according to the invention without having to increase the card spacing. Another advantage is that there are two can plates, each for a full can and an empty can, which has only one drive device for the rotary drive of the two can plates. This makes it possible that only the round can located in the filling position rotates, while the round can outside Filling position not rotated. The round jug outside the filling position can be a full jug for removal or an empty jug for feeding. The particular advantage is that both the full cans and the empty cans can be conveyed from or onto the non-rotating can plate without any problem.

The dependent claims contain advantageous developments of the invention.

The invention is explained in more detail below with reference to exemplary embodiments illustrated in the drawings.

The directions of rotation of the rollers are shown with curved arrows. M is the center (axis) of the drum 4. 4a indicates the clothing and 4b indicates the direction of rotation of the drum 4. The arrow A denotes the working direction of the card K. The card K is upstream of a flake feed device 17. The storage head 19 is rotatably mounted in the storage plate plate 18. The storage head 19 comprises a belt channel 20 with an inlet and an outlet for fiber sliver and a turntable 21, on the underside of which there is a cover. When the can 15 ^I is rotated at the same time, the sliver 14 is deposited in the can 15 ^I in a cycloidal manner, whereby a uniform filling of the can 15 ^I with sliver is possible. To Fig. 1 an empty can is filled with 15 ^I sliver while a full can is conveyed away 15 "with fiber tape (see FIG. Fig. 5c ).

The storage head 19 is a displaceable housing 22 (see FIG. Fig. 4 ) arranged. In front of the depositing head 19, two upstream take-off rollers 23a, 23b with a band funnel 24 are arranged, which are arranged in the common housing 22.

Between the belt deflection roller 32 and the belt funnel 24, a card drafting device 35 can be present, which accordingly Fig. 1a by doing Housing 22 is arranged. The card drafting unit 35 can also (not shown) be positioned upstream of the displaceable housing 22.

The device for filling round cans 15 ₂ , 15 ₃ with sliver 14 detects Fig. 2 a base frame 25 consisting of a support structure. The height of the upper support rods is greater than the height of the round cans 15 ₂ , 15 _3, which are each arranged on a can parking space 26a or 26b. Each can position 26a or 26b has one in Fig. 2a shown in the direction of arrows E, F rotatable can turntable 27a, 27b (known per se) on which the cans 15 ₂ and 15 _{3 are} slowly rotatable in one direction. Between the upper support rods parallel to the plane through the centers of the cans 15 ₂ and 15 _3, two guide means 28a and 28b of an auxiliary frame 29 are mounted, on which the auxiliary frame 29 is slidably mounted in the illustrated embodiment. The housing 22 (see. Fig. 4 ) contains the turntable 21 of the storage head 19 provided with the band channel 20. The curved arrow indicates the direction of rotation of the turntable 21. The sliver 14 runs through the sliver channel 20 and is separated from the card K (see FIG. Fig. 1 ) is supplied. The turntable 21 is in a known manner, for. B. connected by a (not shown) drive belt with a (not shown) drive mechanism.

The auxiliary frame 29 is assigned an adjustment device which, in the exemplary embodiment shown, consists of two double-acting pneumatic cylinders 30a, 30b mounted on the base frame 25 parallel to the guide means 28a, 28b. The pneumatic cylinders 30a, 30b are arranged on the opposite sides of the subframe 29, and their pistons are connected to this subframe 29. The interior of the pneumatic cylinders 30a, 30b is not known in a known manner Actuator shown connected to a source of pressure medium, not shown.

The sliver 14 is from a sliver 14 producing machine, e.g. B. from a card K, the can tray in a known manner and introduced there into the band channel 20 of the rotating turntable 21. Simultaneously with the rotation of the turntable 21, the round can 15 ₃ executes a rotary movement about its axis of rotation on the rotating can plate 27a, so that the sliver 14 is deposited in a cycloid shape.

As soon as the round can 15 ₃ stored under the depositing head is full, the adjusting device of the auxiliary frame 29 starts and very quickly adjusts the auxiliary frame 29 over the next empty round can 15 ₂ , so that the depositing head without stopping the turntable 21 and without lowering its speed of rotation comes to lie over the empty round can 15 ₂ , whereupon the sliver 14 is interrupted, which passes through the band channel of the turntable 21 at unchanged speed without lowering the speed of its supply and is deposited in the empty round can 15 ₂ . After filling the round can 15 _2, the adjusting device (pneumatic cylinder 30a, 30b) moves the auxiliary frame 29 in the direction of the arrows, so that the turntable 21 comes to rest on a new empty can.

In the exemplary embodiment shown, the adjusting device of the auxiliary frame 29 consists of two double-acting pneumatic cylinders 30a, 30b.

In Fig. 3 a plan view of two cards K ₁ , K _{2 is} shown, each of which is followed by a device KW ₁ , KW ₂ according to the invention. In the Devices KW ₁ and KW ₂ each show an empty jug 15 ^I ₁ , 15 ^II ₁ and a full jug 15 ^I ₂ , 15 ^II ₂ . The distance between the cards K ₁ and K ₂ is denoted by a and z. B. be about 1300 to 1400 mm.

The filled arrows indicate the direction of removal of a full can and the empty arrows indicate the direction of supply of an empty can from or to the devices KW ₁ and KW ₂ .

Corresponding Fig. 4 has the sliver 14 between the output of the card K (take-off rollers 11, 12, sh. Fig. 1 ) and a first rotatable belt guide roller 31 a belt section 14 ^I , between the belt guide roller 31 and a second belt guide roller 32 a belt section 14 "and between the belt guide roller 32 and the passage opening into the interior of the housing 22 a belt section 14 ^III . The belt section 14 ^I the shape of an arched loop hanging downwards and forms a belt store.At the same time, when the housing 22 is moved with the storage head 19 in the direction of the arrows B, C by the belt loop 14 ^I , ie the belt storage device, a length compensation of the sliver 14 ^{I takes place} without that the sliver 14 experiences an undesirable change in distortion.

In the 5a to 5e Various phases of the can change (local change of the depositing head 19 from a full can to an empty can) and the can exchange (supply of an empty can and removal of a full can) are shown schematically.

Fig. 5a shows the starting position, in which an empty can 15 _{1 is} arranged below the turntable 21 of the storage head 19 on the can parking space 26a, while another empty can 15 _{2 is} fed to the can parking space 26b in the direction G. To Fig. 5b is the jug 15 ₃ (Full can) on the can space 26a filled with sliver 14, while the empty can 15 _{2 is} present in the can space 26b. Corresponding Fig. 5c the turntable 21 is moved horizontally in the direction B over the empty can 15 ₂ to the can parking space 26b, whereupon the full can 15 _{3 is} removed from the can space 26a in the direction of the arrow H. To Fig. 5d the can 15 ₄ (full can) on the can position 26b is filled, while the can position 26a is supplied with an empty can 15 ₅ in the direction I. According to Fig. 5e the turntable 21 is moved in the direction C over the empty can 15 ₅ , whereupon the full can 15 _{4 is} conveyed in the direction L.

A major advantage is that during the filling (see 5b, 5d ) a full can on a can space below the turntable, which takes a certain amount of time, both a full can and an empty can can be fed to the other can space without time pressure (see 5c and 5d ).

A particular further advantage of the device according to the invention is that the circular cans do not have to be moved while the filling position is being changed and, at the same time, the possible can positions are reduced from 3 to 2. This is achieved by means of a sliding storage head. This means that it is no longer the round cans under the storage head, but this that is moved over the round cans. For this purpose, the head is mounted on a linear guide and moved by a drive when changing. The design of the storage head can be selected so that high accelerations and thus short changeover times are achieved.

The round cans rotate during the filling process to create the typical deposit pattern (cycloids). Now that there are two fill positions, two can plates must also be provided for this rotational movement. However, the two can plates can be driven by a motor, as this is harmless when the full can is replaced by an empty can. That is, both can plates rotate continuously.

With this arrangement, the operator removes the full round can and replaces it with an empty one, which means that only two can positions have to be kept. The space requirement of such a changer is significantly less than the conventional changer.

Especially with regard to steadily increasing card production, an increase in the can diameter is to be expected, which is then possible without the card spacing a (see Fig. 3 ) need to enlarge.

Fig. 6 shows the front view of the device according to the invention Fig. 1 . The storage head 19 is arranged so that it can be pushed back and forth in the direction of the arrows B, C. According to the representation Fig. 6 is the storage head 19 above the round can 15 ₂ , which is filled with sliver 14 ^IV laid in a ring on top of each other. With 15 ₁ an empty round jug is called. The round cans 15 ₁ and 15 ₂ are each arranged on a rotatable can plate 27a or 27b. The can plates 27a, 27b are driven by a controllable drive motor 43, the direction of rotation of which can be reversed in the direction of the arrows N, O. 44a, 44b denote pulleys which are connected to the shaft of the drive motor 43 via belts 45a and 45b, respectively.

To Fig. 7 is an electronic control and regulating device 36, z. B. microcomputer, to which are connected: a control device 37 for the displacement device 38 (z. B. pneumatic cylinder 30a, 30b), a sensor 39 for filling a full can with sliver 14 ^IV , one Motor control device 40 for the drive motor 41, e.g. B. electric motor, for the storage head 19 and a motor control device 42 for the drive motor 43 for the can plate 27a, 27b.

Corresponding Fig. 8a there is a belt drive as a drive means. A drive motor 43 has two pulleys 49a and 49b on its drive shaft. Belt wheel 49a drives belt 45a for can plates 27a; Belt wheel 49b drives belt 45b for can plates 27b. This prevents the driving force from reaching the can plate 27a when the can 15 _{2 is} filled (see Fig. 6 ) and vice versa.

After the in the 8a, 8b In the embodiment shown, two freewheels 47a, 47b are present. Technically, a freewheel is implemented in the prior art by a roller bearing, in which the balls are blocked in one direction of rotation and thus their power transmission is made possible (see Fig. 8c ). The freewheel 47a only transmits clockwise rotation forces.

The function of the freewheels 47a, 47b results, for example, in that the central drive motor 43 rotates counterclockwise to drive the can plate 27b. To drive the can plate 27a, it must turn clockwise.

To fill the can, however, both can plates 27a, 27b must turn in the same direction. In the example mentioned, the direction of rotation must be reversed. When using a belt, the direction of rotation is reversed by crossing (see 9a, 9b ).

In a ball bearing freewheel, the balls lie in a solid cage, which corresponds accordingly Fig. 8c simultaneously leads a number of individually sprung clamping bodies 48. The sprags 48 have in the freewheeling direction their geometric shape "lifting tendency", which leads to the rings (inner ring 49 and outer ring 50) at high speeds up to complete freedom from contact. It is important to have a sufficient relative cage speed from a sufficient radial load on the bearing. This sprag freewheel works continuously and non-positively. The clamping bodies 48 lift off in the freewheeling direction (forward direction) due to the centrifugal force. In the return direction there is a clamping action and thus the locking action due to the pressure of the spring of the clamping body 48 against the rings 49, 50. The inner ring 49 is fixed, for. B. as a press fit, arranged on the drive shaft for the pulleys 44a, 44b, whereby the locking effect against the drive shaft occurs. The outer ring 50 does not rotate.

The invention is illustrated using the example of a sprag freewheel, but also includes other non-positive freewheels, e.g. B. Pinch roller freewheels. Furthermore, the invention includes both unsupported freewheels in which the shaft by separate bearings, for. B. roller bearings, is also stored as freewheels (combination), in which the freewheel and z. B. the rolling bearing (ball bearings, cylindrical roller bearings, needle bearings, barrel bearings) form an integral component.

The 9a, 9b show the reversal of the direction of rotation of the drive motor 43 and the uncrossed and crossed drive belts assigned to the drive shaft.

There are several known principles for reversing the direction of rotation. For example, it can be after 10, 10a a gear 53 (z. B. gears 51, 52) are presented.

According to the invention, an economical implementation of the can plate drive is made possible for a device in which two can positions can be filled with a displaceable storage head 19.
