Description

Title: Device for filling a jug with sliver

Description The invention relates to a device for filling a can with sliver, which is used in a spinning preparation plant, e.g. Track, carding or combing machine is produced, wherein the device is adapted to receive an empty and a full pot at the same time, comprising a storage head with an integrated turntable. In the known state of the art, the sliver supplied by the spinning preparation machine is taken over by a so-called sliver deposit. The sliver is guided via guide aids via a sliver funnel to a calender roll pair, which deposits the sliver on a turntable in the waiting cans. If the jug is filled, the sliver is cut through, at the same time the full jug is removed and an empty jug is nachgeschoben. The can changers have linear or rotary can changers, which have different advantages depending on the shape and size of the can and the space available. In contrast to rotary can changers, linear can changers have a very compact design and are used where the concept of the spinning preparation machine only allows for a narrow installation space.

When the can is changed, the round cans are moved and change positions. For this purpose, the filing speed must be reduced as a rule, since otherwise fiber material is conveyed between the round cans. However, from the customer's point of view, a quick change of the round cans is desirable, so that the production of the card is not worth mentioning must be reduced. Furthermore, fluctuations in the weight of the band occur during large changes in the delivery speed, which can adversely affect the technological result up to the end product. However, a quick change of the round cans is associated with various difficulties. The round cans have no 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, the round cans have a high weight in the filled state, which causes high forces during short change times during acceleration.

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

In spinning mills, more sliver is often filled into the cans than they can absorb. Thus, the spirally laid slivers are strongly compressed, the counterforce must be absorbed by the holder of the turntable. If the jug is overfilled, creates a strong pressure on the holder of the turntable by the overflowing sliver when removing the pot. If the jug is removed, the friction between the pressed sliver and the turntable can cause the upper layers of sliver to slip and be pulled out of the jug. Another Processing the sliver on a subsequent machine thus becomes time consuming.

For example, according to DE 4333730 A1 a can changer for elongated non-circular cans, for example rectangular cans, with a movable bottom or conveyor, in which the cans can be moved linearly under a turntable. Orthogonal to the conveying direction of the cans a turntable is slidably disposed, which can move along a guide over the full length of the can. When changing from a full to an empty can, both the bottom or the conveyor can be moved linearly, as well as the turntable with its guide in the opposite direction. Again, there is the problem of overloading on all moving parts when the pot is overcrowded and should be promoted under the turntable out.

Furthermore, the movement of the tray or turntable within the subframe results in a relative movement between the tray and the frame, which is undesirable. The components are to be adjusted to each other and additional elements such as sheet metal covers must be used to close openings that result from the process of the storage tray again. Also, the wear and the sensitivity to dirt between the moving components is undesirable. Another major disadvantage is the multiple support of the frame structure to all four sides, so that the space for the accessibility of the cans is limited. The object of the invention is the development of a device for linear change of a pot. In particular, the device should be structurally simple and be freely accessible from three sides for a flexible and easy can change. This object is achieved with the features of claim 1, with a device for filling a pot with sliver, which is produced in a spinning preparation plant, such as track, carding machine or comber, the device is adapted to receive an empty and a full pot at the same time, and a storage head with an integrated turntable.

The invention includes the technical teaching that the storage head is slidably mounted from a first position above a first can to a second position above a second can. In contrast to the prior art, not the turntable within the storage head is moved horizontally, but the entire storage head, which significantly facilitates the extension of the full pot, especially a crowded jug. Another important advantage of the invention is that the storage head can be moved at a higher speed, since it is not as unstable as cans and whose mass is less than the mass of a filled pot. Due to the shorter changeover time from the filling of a full to an empty can, the card during the change time can be driven at a higher speed than in the prior art, since the speed produced by the carding sliver does not have to be lowered significantly in speed. The productivity of the card increases thereby. An integration of the turntable in the storage head allows a flat design and a flat bottom of the storage head, whereby the discarded sliver of a possibly overcrowded pot is not dragged when moving the storage head. In a preferred embodiment, the device has a base plate with a rear wall, which is designed as a frame, wherein the storage head is arranged exclusively directly or indirectly on the frame displaceable. This can be dispensed with the front wall and the side walls of the can changer, so that a can changer is created, which is completely accessible from three sides. The storage head can be arranged and stored directly on the frame or on the rear wall, for example via an angular arrangement or extension of the storage head. But it can also be arranged and stored indirectly on the frame or the rear wall, for example by a drive housing connected to the storage head in a rigid construction and both combined. Preferably, two guides are arranged to support the storage head on the frame, which are spaced apart in the vertical direction. Thus, both the weight forces as well as the resulting on and through the storage head torques can be absorbed. As a space-saving solution has been found to connect the storage head with a drive housing, which is arranged between the guides. The vertical distance of the guides thus substantially corresponds to the height of the drive housing, which can accommodate the drive elements such as gear motor, drive elements, etc. and builds very flat.

In a preferred embodiment, the drive housing has bearings that interact with the guides. In this case, a bearing is always arranged above and below the drive housing.

Characterized in that an upper bearing has at least one pair of rollers, with a perpendicular to the base plate arranged leg of the Guiding cooperates, and that a lower bearing has at least one pair of rollers which are arranged at right angles to each other interact with the guide, can be lifted by the disassembly of the leg of the entire drive head and maintained.

For this purpose, the lower guide has a convex contour, which may preferably be formed as a round rod.

A further improvement is achieved in that the device comprises two guide rollers which are arranged on the storage head, wherein at least one guide roller is pivotable such that the

Sliver is guided perpendicular to the axis of rotation. By the

Pivoting the guide rollers in each procedure or

Moving the storage head is a perpendicular to the sliver running direction ensures leadership, with a

Jump off the sliver from the guide roller and thus a

Band break is avoided.

Further, measures improving the invention will be described in more detail below together with the description of a preferred embodiment of the invention with reference to FIGS. Show it:

Storage of the storage head.

The can changer according to FIGS. 1 to 3 essentially comprises a rectangular base plate 10, in which two can plates 11, 12 are rotatably arranged. The base plate 10 serves as a standing or moving surface for the cans, which are moved or transported transversely to the longitudinal direction of the base plate 10. The base plate 10 has substantially a size or length which is suitable to receive two cans side by side. In the illustration of Figure 1, a full or to be filled can 31 is shown on the left and an empty can 30 on the right. Each can 30, 31 stands on its own rotatably driven can plate 11, 12, the drive is integrated in the base plate 10. Above the full or to be filled can 31 is a Storage head 13 with an integrated turntable 14 is arranged. Not shown sliver is guided, for example, from a card over the guide rollers 16 and 17 to an opening in the storage head 13 to the turntable 14, which rotates within the storage head 13. Due to the rotation of the full can 31 due to the rotating can plate 12 in combination with the rotation of the turntable 14, the sliver is deposited within the can 31 in the form of a cycloid. Below the storage head 13, a cover 15 is mounted, with which the upper open side of the pot 31 can be completely covered, so that especially at the end of the filling process, the sliver can not laterally between the storage head 13 and pot 31. The storage of the storage head 13 with the turntable 14 and the cover 15 takes place exclusively on the frame 18, which extends only on a single longitudinal side of the can changer 1 , The can changer 1 thus has three completely open sides without supports, etc., and a rear wall, which is designed as a frame 18 and on which the storage head 13 including the turntable 14 and the cover 15 is arranged displaceably or movably. For this purpose, the frame 18 has at least two lateral supports 19a, 19b which are fastened to the base plate 10 in the region of the narrow end faces. Substantially perpendicular to the supports 19a, 19b, additional supports 20a, 20b are arranged on them, which form part of a rear wall for the can changer 1. This rear wall has a cladding 21, which can cover other mechanical elements such as drive elements or supply lines (power cable, exhaust, etc.). The cladding 21 serves, inter alia, as pinch protection for the operator when the storage head 13 moves horizontally. Below and above the panel 21 18 guides 25, 26 are arranged on the frame, which cooperate with bearings 23, 24 of a drive housing 22 to which the storage head 13 is attached. In Figure 1, the storage head 13 is positioned over the full or to be filled can 31. The empty can 30 can be moved during the filling process in the retraction or extension direction 32, 33.

If the can 31 is filled, the storage head 13 (see FIG. 2) moves into a position over the empty can 30, so that the full can 31 can be removed and a new empty can can be positioned on the can plate 12. FIG. 2 also shows an attached ramp 10a, via which the cans can be moved in or out more easily onto the can plates 11, 12. To change the cans, the sliver is separated within the storage head 13. Simultaneously with the sliding movement of the storage head 13 into a position above the empty can 30, at least the guide rollers 17 are pivoted such that the sliver always runs perpendicular to the rotation axis via the guide rollers 16, 17. This simultaneous pivoting of the guide roller 17 with the sliding movement of the storage head 13 allows only the displacement of the storage head 13 with the turntable 14, otherwise the band can jump down from the roll 17, which in turn can lead to band breakage. The storage head 13 moves with the turntable 14 and the cover 15 horizontally to the base plate 10 along the guides 25 and 26, which are arranged on the frame 18. With the guides 25, 26 bearings 23, 24 cooperate, which are arranged on a drive housing 22.

According to Figure 4, the drive housing 22 is in turn connected in one piece or in several parts with the drive head 13, wherein the compound has a high rigidity. The drive head 13 is arranged parallel to the base plate 10, whereas the drive housing 22 is arranged perpendicular to the base plate 10. The drive housing 22 is thus arranged at right angles to the drive head 13, or parallel to the frame 18. The drive housing 22 receives the drive components, not shown, for example, a geared motor, which moves with a gear along a toothing, which is arranged behind the panel 21. At the upper portion of the drive housing 22, a bearing 23 is arranged, which is supported on a guide 25. The guide is L-shaped, wherein a leg 25a of the guide 25 is perpendicular to the base plate 10. At least two rollers 23 a, 23 b cooperate with this leg, which thus prevent sagging or pushing up of the cover 15 with the storage head 13. Preferably, at least two pairs of rollers 23a, 23b are arranged distributed over the width of the drive housing 22. They absorb the forces acting horizontally or parallel to the base plate 10 on the storage head 13 and caused by the weight of the storage head 13 with the turntable 14 and the cover 15, or by the push-up force of the deposited fibers. The rollers 23a, 23b thus rotate in the horizontal direction.

The bearing 24, which is arranged below the drive housing 22, has at least two rollers 24a, 24b, which are arranged substantially at right angles to each other and cooperate with a guide whose guide surfaces are also arranged complementary to the bearing 24. In this embodiment, the guide 26 is formed with its guide surfaces as a round bar on which the rollers 24a, 24b are supported with a complementary concave radius. Since the weight of the storage head 13 with the rotary divider 4, the cover 15 and the drive housing load on this guide, and at the same time a tilting or torque due to the support acts on the upper bearing 23, an arrangement of the rollers 24a, 24b in an angle of 45 ° to the vertical or horizontal proved optimal. Again, at least two pairs of rollers 24a, 24b are preferably distributed over the width of the drive housing 22. In contrast to the prior art, not the turntable 14 is moved horizontally within the storage head 13, but the entire storage head 13, which significantly facilitates the extension of the full pot 31, in particular a crowded jug. Characterized in that the storage head 13 is movably mounted on a frame 18 which extends perpendicular to only one side of the base plate 10, there is a can changer, the three sides and about half of the top - when the storage head 13 has been moved - completely is accessible.

Due to the displacement of the drive components of a displacement device of the cans to an integrated solution in the rear wall for moving the storage head results in a flat-built can changer, in which the can almost at ground level can enter the can changer and no major differences in height when driving in and out has to overcome , This also allows a minimum distance from the top can edge to the storage tray are maintained. Alternatively, however, the can change with the base plate can be easily integrated into the hall floor to eliminate the approximately 5 cm difference in height from the hall floor to the base plate. Another significant advantage of the invention is that the storage head can be moved at a higher speed, since its mass is less than the mass of a filled pot. Due to the shorter changeover time from the filling of a full to an empty can, the card during the change time can be driven at a higher speed than in the prior art, since the speed produced by the card sliver does not have to be lowered significantly in speed. The productivity of the card increases thereby. reference numeral
