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 is not significantly reduced must become. Furthermore, with large changes in the delivery speed, fluctuations in the belt weight occur, which can have a negative impact on the technological result up 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 known devices, the storage head is stationary over the rotating round can to be filled and deposits the sliver in a cycloid shape. A disadvantage of this storage is that the so-called crossing points of the cycloids of all layers lie one above the other in the vertical direction in the can. At each of these crossing points, two strip sections lie one above the other within a layer, which leads to a local increase in thickness at these points. As a result, the fill level increases more rapidly in the area of the crossing points than in the other areas of the storage area, which means that the available space Filling volume of the jug is not optimally used. With constant rotation speeds of the depositing head and the round can, the deposit density of the sliver in the round can is not uniform. In the vicinity of the axis of rotation of the round can and near the inner circumferential surface of the round can, more sliver is accumulated due to the above-mentioned superimpositions than in the concentric central region (depression) located between the two regions. The crossing points are both inside and outside - seen in plan view - each on a circle. The stored sliver is compressed unevenly by the turntable and the capacity of the round jug is not fully used.

The US 2571880 A discloses a device whose storage head can be pivoted back and forth between the filling positions of two cans.

The invention is therefore based on the object of creating a device of the type described at the outset which avoids the disadvantages mentioned, which occur in particular when changing cans, i.e. H. when changing the local assignment between the storage head on the one hand and a full can and an empty can on the other hand, prevents movement of the round cans, allows a shorter time for changing the cans and allows the storage density of the sliver in the round can to be evened out in a simple manner.

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

The fact that the storage head can be moved locally from a full can to an empty can to change the can, and that the can can be exchanged even while an empty can is being filled Full can can be removed and a new empty can can be fed in, the possible can positions are reduced from three positions to two positions. According to the invention, the round cans are no longer displaced under the depositing head, as in the known devices, but the depositing head is displaced 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 a view to steadily increasing card production, an increase in the can diameter is to be expected, which is then possible with the device according to the invention without having to increase the card spacing. The fact that the storage head is displaced locally during the filling is a further advantage in that the position of the crossing points is varied, ie the crossing points are freely distributed. The intersection points are preferably as congruent as possible in the vertical direction, ideally not at all. As a result, the storage density of the sliver in the round can is evened out. A further particular advantage is that the displacement of the depositing head is accomplished in a structurally simple manner both during the filling process in order to homogenize the sliver deposit as well as to change the can from a full can to an empty can.

The dependent claims contain advantageous developments of the invention.

According to the invention, the can change is preferably carried out when a round can is filled with sliver.

Alternatively or additionally, the storage head can be linearly displaceable. The storage head can be moved linearly, for. B. linear guide. He can also on a circular path, for. B. around a fulcrum. It is also possible for the storage head to be mounted such that it can be moved back and forth.

The storage head is preferably moved pneumatically, e.g. B. impression cylinder. Mechanical displacement, e.g. B. gear or the like, possible. The storage head can be driven by a motor, e.g. B. electric motor. The direction of rotation of the electric motor can be reversible. The storage head can be accelerated and braked for displacement.

The storage head is rotatably mounted on a carrier which can be driven to oscillate.

Alternatively or additionally, the storage head can be arranged on a straight-guided, oscillatingly driven auxiliary frame. The subframe can be a sled or the like.

The oscillating movements of the carrier preferably take place by means of a driven gear, such as a crank gear or a push crank. The transmission can also have a crank epicyclic gear and / or a rack that meshes with a driven gear.

The storage head can be arranged so as to be adjustable in the direction of the plane by the axes of rotation of the round cans.

The storage head is preferably mounted on an auxiliary frame which is adjustable on the guide means attached to the base frame in the direction of the plane by the rotary machine and which is coupled to an adjusting device of the auxiliary frame. The adjustment device of the subframe preferably consists of two double-acting pneumatic cylinders.

The tray head is preferably moved in the horizontal direction to change the can.

When changing the jug, the full jug and the empty jug are preferably stationary. More preferably, the round can is stationary during the filling process below the storage head. With the relocation of the depositing head, the filling position preferably changes when the can is changed. By means of the displaceable storage head, two empty cans can be filled with sliver one after the other.

To change the can, the storage head is moved essentially perpendicular to the working direction of the card.

A belt storage device (take-off rollers, belt deflection roller) is preferably present between the depositing head and the exit of the card.

The position of the storage head before the displacement and the position of the storage head are arranged immediately next to one another after the displacement, the respective axes of rotation being at a shorter distance from one another.

The drive for the displacement of the depositing head and a measuring device for filling the round can with fiber sliver are preferably connected to a common electrical control and regulating device.

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

Trützschler card TC, with feed roller 1, dining table 2, licker-in 3a, 3b, 3c, drum 4, taker 5, doctor roller 6, pinch rollers 7, 8, fleece guide element 9, pile funnel 10, take-off rollers 11, 12, revolving cover 13 with cover deflection rollers and Flat bars, cans 15 ', 15 "and can stick 16. The directions of rotation of the rollers 3a-c, 4, 5 are shown with curved arrows. M _T denotes the center (axis) of the drum 4. 4a gives the set and 4b gives 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 depositing head 19 is rotatably mounted in the depositing plate 18. The depositing head 19 comprises a belt channel 20 with an inlet and an outlet for sliver and a turntable 21, on the underside of which there is a cover, and when the can 15 'is rotated at the same time, the sliver 14 is deposited in a cycloidal shape in the can 15', resulting in a uniform Filling the can 15 'with sliver 14 is possible.

To Fig. 1 an empty jug 15 'is filled with sliver, while a full jug 15 "is removed with sliver 14 (cf. 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 is arranged in the housing 22. 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 25a, 25b parallel to the plane through centers of the cans 15 ₂ and 15 _3, two guide means 28a and 28b of a subframe 29 are mounted, on which the subframe 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, not designated, 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 z. 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 connected in a known manner to a source of pressure medium, not shown, via an actuating device, 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 19 is full, the adjusting device 30a, 30b 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 19 without stopping the Turntable 21 and without lowering its speed of rotation comes to rest on the empty round can 15 ₂ , whereupon the sliver 14 is interrupted, which passes through the band channel 20 of the turntable 21 at unchanged speed without lowering the speed of its supply and placed in the empty round jug 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 one of the arrows B, C, so that the turntable 21 comes to rest on a new empty can.

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 devices KW ₁ and KW ₂ , an empty can 15 ' ₁ , 15 " ₁ and a full can 15' ₂ , 15" ₂ are shown. 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 H ₁ , H ₂ , J ₁ , J ₂ show the direction of the removal of a full can 15 ' ₂ , 15 " ₂ and the empty arrows G ₁ , G ₂ , I ₁ , I ₂ , the direction of the supply of a Empty jug 15 ' ₁ , 15 " ₁ 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 ', 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"'. The band section 14 'has the shape of a band loop sagging downward and forms a band store. At the same time, when the housing 22 is displaced with the storage head 19 in the direction of the arrows B, C through the band loop 14 ', ie the band storage device, the length of the sliver 14 is compensated for without the sliver 14 experiencing 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 the can 15 ₃ (full can) on the can position 26a is filled with sliver 14, while on the can position 26b there is an empty can 15 ₂ . 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 H.

A major advantage is that during the filling (see 5b, 5d ) a full can 15 ₃ , 15 ₄ on a can position 26a, 26b below the turntable 21, which takes a certain amount of time, both a full can and an empty can 15 ₂ , 15 ₅ on the other can position 26a, 26b without time pressure can be supplied (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 the possible can positions at the same time to reduce from three to two. This is achieved by means of the displaceable depositing head 19. This means that it is no longer the round cans under the depositing head 19 that are moved over the round cans. For this purpose, the head 19 is mounted on a linear guide and is moved by a drive when changing. The design of the storage head 19 can be selected so that high accelerations and thus short change times are achieved.

The round cans rotate during the filling process to create the typical deposit pattern (cycloids). Since there are now two filling positions, two can plates 27a, 27b must also be provided for this rotational movement. However, the two can plates 27a, 27b can be driven by a motor 43, since 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 the storage head 19 is located above the round can 15 ₂ , which are ring-shaped one above the other stored sliver 14 ^{IV is} filled. 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 L, M. 44a, 44b denote pulleys which are connected to a 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. microcomputers, to which are connected: a control device 37 for the displacement device 38 (e.g. pneumatic cylinder 30a, 30b), a sensor 39 for filling a full can with sliver 14 ^1V , a motor control device 40 for the drive motor 41, z. 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.
