Definitions

  • 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 has been produced, wherein the device is adapted to receive an empty and a full can at the same time, comprising a storage head with a turntable.
  • a spinning preparation plant e.g. Track, carding or combing machine has been produced
  • the device is adapted to receive an empty and a full can at the same time, comprising a storage head with a turntable.
  • 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.
  • 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.
  • the round cans 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.
  • a quick change of the round cans is desirable, so that the production of the card is not worth mentioning must be reduced.
  • 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.
  • 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.
  • the round cans differ from customer to customer, which makes the adaptation of recordings difficult.
  • the round cans have a high weight in the filled state, which causes high forces during short change times during acceleration.
  • 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.
  • 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.
  • 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.
  • 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.
  • both the bottom or conveyor can be moved linearly, as well as the turntable with its guide in the opposite direction.
  • 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.
  • 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 changing a jug.
  • the device should be structurally simple and be freely accessible from three sides for a flexible and easy can change.
  • This object is achieved by a device for filling a can with sliver, which is used in a spinning preparation plant, e.g. Track, carding or comber was made, the device is adapted to receive an empty and a full can at the same time, solved according to the preamble of claim 1 and with the respective characterizing features.
  • the invention includes the technical teaching that a pivotally mounted storage head during the pivoting movement, when the full pot has to be changed, is supported by the pressed sliver in the vertical movement.
  • the device with the pivotable storage head can be designed so that after lifting the storage head only the full pot is removed, and an empty pot is moved from a waiting position to a filling position.
  • the base plate is indeed suitable to accommodate two cans, but in this variant only equipped with a turntable.
  • the storage head is pivotable from a first position above a first can to a second position above a second can.
  • the second can already be positioned.
  • the storage head pivots in a radius of the filled first Jug over the empty second jug.
  • the upper deposited layer sliver is not moved and the pivoting device is structurally much easier to implement than a sliding solution, since it can be worked with larger tolerances.
  • the storage head can be supported by at least two supports.
  • the storage and pivoting of the storage head by at least two supports allows maximum access to the space under the storage head to change the cans. This makes it possible for the device to be completely accessible from three sides.
  • the at least two supports are pivotable by at least one drive element. It is thus an automatic can change possible.
  • the drive element may be designed as a cylinder which is pneumatically actuated. The result is a kinematics, which provides no clamping points and thus is very safe for the operator.
  • the pivoting movement of the at least two supports takes place about the pivot points A and B, which are arranged in the region of the base plate.
  • the time to change the jug is minimized because most of the pivoting movement is in the horizontal direction.
  • the storage head is pivotably supported by two further supports.
  • the storage head thus receives a high stability.
  • one or more supports may be formed to receive electrical leads or air ducts and lead to the storage head.
  • the distance of the storage head to the top of the pot can be adjusted.
  • the device is adjustable to the different can sizes of customers.
  • Fig. 1 is a side view of the invention
  • FIG. 2 is a perspective view of the can changer according to the invention in a second embodiment
  • Fig. 3 is a detail of a support.
  • the can changer according to FIG. 1 essentially comprises a rectangular base plate 10 into which a first and a second can plate 11, 12 are integrated.
  • the base plate 10 thus has substantially a size or length which is suitable to receive two cans in a row.
  • a full can 31 or an almost filled can is shown in the left-hand region, and an empty can 30 is shown in the right-hand region.
  • the can plates 11, 12 are rotatably disposed within the base plate 10 and can be rotated by a common drive, not shown.
  • the drive is preferably also arranged in or under the base plate 10 and can simultaneously or alternately drive the can plates 1, 12.
  • An almost full can 31 is in the left position, with a storage head 13 with an integrated turntable 14 located above the upper can edge.
  • About the turntable 14 sliver, for example, from a card, promoted in the pot.
  • the sliver is deposited as a cycloid in the can 31 in a known manner.
  • the storage head 13 is supported by a system of at least two supports adapted to pivot the storage head 13 from a first position above a first can to a second position above a second can.
  • the storage head 13 is held and pivoted by four supports 15a, b and 16a, b, in which representation only the front supports 15a, 16a are visible.
  • the rear supports 15b, 16b are arranged on the opposite side of the storage head 13, which extends over the full can width, so that the cans fit between the supports 15a, b, 16a, b.
  • a drive element acts on at least one support 16a, in this exemplary embodiment a cylinder 17 which is suitable for pivoting the supports 15a, b and 16a, b about a pivot point A, B, C, D, respectively.
  • the sliver If the full can 31 is finally filled and possibly also overfilled, the sliver generates a compressive force between the storage head 13 and the can plate 11. After severing the sliver by a separating device, not shown, which is integrated in the storage head 13, the storage head 13 pivots from the full pot 31 over to the empty pot 30, which has been positioned in the meantime on the tray 12 and is already turning.
  • the pivotal movement of the storage head 13 is supported by the pressure force of the filled or overfilled jug, which has the advantage in comparison to the prior art that there is no friction-loaded relative movement between the sliver and the storage head 13.
  • the cylinder 7 pulls on the support 16a such that all the supports 15a, b, 16a, b pivot about their respective pivot points A, B, C, D and thus the storage head 31 from the first position over the full can 31 Move a second position over the empty can 30 (dashed line).
  • the final position of the storage head 13 in the first and in the second position can by a stop are limited, for example, with at least one of the supports 15a, b, 16a, b cooperates.
  • the stop can also fix the position of the storage head 13, so that first the fixation must be released before a new pivoting movement. This can be done automatically, semi-automatically or manually.
  • Figure 2 shows a second embodiment of the can changer according to the invention 1.
  • the storage head 13 extends with the turntable 14 only over part of the can width and is thus designed much narrower.
  • the storage head 13 is supported only by two supports 15a, 16a, which are stabilized for reasons of stability, each with its own further support 18, 19.
  • These smaller supports 18, 19 are fastened in the lower region to about half the height of the supports 15a, 16a with and on these.
  • the pivot points A and B thereby lengthen, since the supports 15a and 18 and the supports 16a and 19 each form a kinematic triangle, which is pivotable about the pivot points A and B respectively.
  • the pivot points A and B are designed as sealed against dirt spherical roller bearings or ball bearings, as they must absorb the weight of the storage head 13, but with a crowded pot and the load from the pressure force of the compressed fiber slivers must withstand.
  • the pivot points C and D are performed with closed bearings to prevent contamination.
  • the storage head 13 sits with the turntable 14 on the full pot 31.
  • the empty pot is not yet positioned, so that here the can plate 12 can be seen. If a new empty can 30 is driven onto the base plate 10 via the ramp 10a and then positioned on the can plate 12, the sliver can be separated and the tray 13 is pivoted to the position above the empty can.
  • the storage head 13 lifts from the full pot 31, wherein the pressure of the compressed fiber sliver the Take off and thus support the panning process.
  • the pivoting movement is effected by a drive, which can be advantageously designed as a pneumatic cylinder.
  • the pivoting movement can be modified so that the lifting and placing of the storage head is carried out slowly, but the movement in the central area is faster.
  • the kinematics of the pivoting device can be designed and encapsulated so that no nips arise that could endanger the operator.
  • the respective end position can be adjusted by stops, for example by stop screws. Also in this embodiment, the stop for the respective end position can be formed to fix the supports 15a, 16a.
  • the supports 15a, 16a may be formed as at least partially hollow profile to receive a suction or electrical supply line. It would be useful to have a support 15a or 16a adapted to receive a pipe or hose for the suction. The other support 15a or 16a would then receive the electrical and / or pneumatic supply line.
  • supports 15a, 16a, 15b, 16b are useful, which are telescopically extendable. This can be done - under magnification or reduction of the swivel angle - an adaptation to different can heights. For example, both cans with a height of 1,000 mm, as well as cans with a height of 1,200 mm can be used. The adjustment of the swivel angle via the drive and the adjustable stops.
  • a modified support which may be the support 15 a or 16 a of Figure 2.
  • the support 15a is connected to the support 18 of Figure 2 by means of a welded connection combined.
  • the support 15 a has a cavity 20, can be routed through the lines or a suction (arrow), which extend up to the storage head 13.
  • the opening 21 for the cavity 20 is disposed above the bearing 22, which thus forms the pivot point A.
  • the bearing 22 may be formed as a ball bearing, which is correspondingly encapsulated against dirt.
  • the can changer according to the invention has over the prior art has the advantage that it is fully accessible from three sides, which facilitates the can change.
  • the swivel device is much more robust and dirt-resistant and can be equipped with larger tolerances, as a sliding storage head.
  • the system can be used both for round cans, as well as rectangular cans.
