Definitions

  • the invention relates to a device for filling a jug with sliver, which is used in a spinning preparation plant, e.g. Draw frame, card or combing machine was produced, the device being suitable for receiving an empty and a full can at the same time, comprising a depositing head with a turntable.
  • a spinning preparation plant e.g. Draw frame, card or combing machine was produced
  • the sliver supplied by the spinning preparation machine is taken over by a so-called sliver reel.
  • the fiber sliver is guided via guide aids via a belt funnel to a pair of calender rollers, which deposits the fiber sliver into the ready cans via a rotary plate.
  • the jug is full, the sliver is cut, the full jug being removed and an empty jug being pushed at the same time.
  • There are linear or rotary can changers for the 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 are very compact and are used where the concept of the spinning preparation machine allows only a small space.
  • the round cans 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 worth mentioning must be reduced. 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.
  • 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.
  • 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.
  • a can changer for elongated, non-round cans for example rectangular cans, with a movable floor or conveyor, in which the cans can be moved linearly under a turntable.
  • a turntable is slidably arranged orthogonally to the conveying direction of the cans and can move along a guide over the entire length of the cans.
  • both the bottom or conveyor can move linearly, as can the turntable with its guide in the opposite direction.
  • the movement of the storage plate or turntable within the subframe leads to a relative movement between the storage plate and the frame, which is undesirable.
  • the components have to be adjusted to each other and additional elements such as sheet metal covers have to be used to close openings that result from the movement of the storage plate. Wear and dirt sensitivity between the moving components is also undesirable.
  • Another major disadvantage is the multiple support of the frame construction on all four sides, so that the space for the accessibility of the cans is restricted.
  • the object of the invention is the development of a device for changing a jug.
  • the device should be of simple construction and should be freely accessible from three sides for a flexible and easy can change.
  • the invention includes the technical teaching that a pivoted storage head during the pivoting movement, when the full can has to be replaced, is supported in the vertical movement by the pressed fiber sliver. Because the storage head is swiveled away from the top of the can within a radius, there is no friction between the underside of the storage plate and the sliver, so that this is not changed in the storage (cycloid shape).
  • the device with the pivotable depositing head can be designed such that after the depositing head has been lifted off, the full can is only removed and an empty can is moved from a waiting position into a filling position.
  • the base plate is suitable for holding two cans, but in this variant it is only equipped with a turntable.
  • the storage head can be pivoted from a first position above a first can to a second position above a second can. This means that the second can can already be positioned while the first can is being filled.
  • the storage head swivels in a radius from the filled first Jug over the still empty second jug.
  • the upper layer of fiber sliver is not shifted and the pivoting device is structurally much easier to implement than a sliding solution, since larger tolerances can be used.
  • the storage head is supported by at least two supports.
  • the storage and swiveling of the storage head by at least two supports enables maximum access to the space under the storage head in order to change the cans. It is therefore possible for the device to be fully accessible from three sides.
  • the at least two supports can be pivoted by at least one drive element. An automatic can change is therefore possible.
  • the drive element can preferably be designed as a cylinder which can be actuated pneumatically. The result is kinematics that do not provide any clamping points and are therefore very safe for the operating personnel.
  • 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.
  • this results in a very gentle swiveling movement due to the length of the support and thus the swivel radius, in which the depositing head only slightly lifts off the full can.
  • the time for changing the jug is minimized because the majority of the swivel movement is in the horizontal direction.
  • the supports are arranged parallel to one another in the pivoting direction, that is to say form a parallelogram when pivoting, the maximum free space for changing the cans is achieved, since three sides of the device are fully accessible.
  • the storage head is pivotably supported by two further supports. This gives the storage head a high degree of stability.
  • One or more supports can preferably be designed to receive electrical lines or air lines and to lead them to the storage head.
  • the distance between the storage head and the upper edge of the jug can be adjusted.
  • the device can thus be adjusted to the different sizes of cans of the customers.
  • cans are to be used that are, for example, 100 mm higher than the previous cans, it makes sense to design the supports so that they can be extended telescopically. This means that the swivel angle becomes smaller with a larger radius, which in turn can be set or limited by the stops.
  • the can changer after Figure 1 essentially comprises a rectangular base plate 10, in which a first and a second can plate 11, 12 are integrated.
  • the base plate 10 thus essentially has a size or length that is suitable for accommodating two cans in a row.
  • a full can 31 or an almost full can is shown in the left area, and an empty can 30 is shown in the right area.
  • the can plates 11, 12 are rotatably arranged within the base plate 10 and can be set in rotation via 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 11, 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 edge of the can.
  • Sliver for example from a card, is fed into the can via the turntable 14.
  • the turntable 14 By rotating the turntable 14 in combination with the rotation of the can 31 the sliver is deposited as a cycloid in the can 31 by the can plate 11 in a known manner.
  • the storage head 13 is supported by a system of at least two supports which are suitable for pivoting 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, only the front supports 15a, 16a being visible in this illustration.
  • the rear supports 15b, 16b are arranged on the opposite side of the storage head 13, which thus extends over the full width of the can 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 respective pivot point A, B, C, D. 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 the sliver has been cut by a separating device, not shown, which is integrated in the storage head 13, the storage head 13 pivots from the full can 31 over to the empty can 30, which has been positioned in the meantime above the tray 12 and is already rotating.
  • the pivoting movement of the depositing head 13 is supported by the pressure force of the filled or overfilled can, which has the advantage in comparison with the prior art that there is no frictional relative movement between the sliver and the depositing head 13.
  • the cylinder 17 pulls on the support 16a in such a way that all 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 in 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 can be limited, which interacts, for example, with at least one of the supports 15a, b, 16a, b.
  • the stop can also fix the position of the storage head 13, so that the fixation has to 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 1 according to the invention.
  • the storage head 13 In contrast to the embodiment of the Figure 1 extends the storage head 13 with the turntable 14 only over part of the can width and is thus made much narrower.
  • the storage head 13 is only supported by two supports 15a, 16a, each of which is stabilized with its own further support 18, 19 for reasons of stability.
  • These smaller supports 18, 19 are fastened with and to the lower region up to approximately half the height of the supports 15a, 16a.
  • the pivot points A and B are extended because the supports 15a and 18 and the supports 16a and 19 each form a kinematic triangle which can be pivoted about the pivot points A and B, respectively.
  • the fulcrums A and B are designed as spherical roller bearings or ball bearings, which are encapsulated against dirt, since they have to absorb the weight of the storage head 13, but also have to withstand the load from the compressive force of the compressed fiber slivers in the case of an overfilled can.
  • Pivots C and D are also designed with closed roller bearings to prevent contamination.
  • the storage head 13 with the turntable 14 sits over the full can 31. The empty can has not yet been positioned, so that the can plate 12 can be seen here. If a new empty can 30 is moved over the ramp 10a onto the base plate 10 and then positioned on the can plate 12, the sliver can be separated and the storage head 13 is pivoted into the position above the empty can.
  • the storage head 13 lifts off the full can 31, the pressure of the compressed fiber sliver Take off and thus supports the swiveling process.
  • the pivoting movement is carried out by a drive, which can advantageously be designed as a pneumatic cylinder.
  • the swiveling movement can be modified in such a way that the lifting and placing of the storage head is carried out slowly, but the movement takes place more quickly in the central area.
  • the kinematics of the swivel device can be designed and encapsulated in such a way that there are no clamping points that could endanger the operating personnel.
  • the respective end position can be adjusted by stops, for example by stop screws.
  • the stop can be designed for the respective end position to fix the supports 15a, 16a.
  • the supports 15a, 16a can be designed as an at least partially hollow profile in order to receive a suction or electrical supply line.
  • a support 15a or 16a would expediently be designed to receive a tube or a hose for the suction.
  • the other support 15a or 16a would then take up the electrical and / or pneumatic supply line.
  • supports 15a, 16a, 15b, 16b are expedient, which can be extended telescopically. This allows you to adapt to different can heights - by increasing or decreasing the swivel angle. For example, both cans with a height of 1,000 mm and cans with a height of 1,200 mm can be used.
  • the swivel angle is adjusted via the drive and the adjustable stops.
  • a modified support which consists of the support 15a or 16a Figure 2 can be.
  • the support 15a is made with the support 18 Figure 2 by means of a welded joint been combined.
  • the support 15a has a cavity 20 through which lines or a suction (arrow) can be laid, which extend into the storage head 13.
  • the opening 21 for the cavity 20 is arranged above the bearing 22, which thus forms the fulcrum A.
  • the bearing 22 can be designed as a ball bearing which is encapsulated accordingly against dirt.
  • the can changer according to the invention has the advantage over the prior art that it is completely accessible from three sides, which makes it easier to change the can.
  • the swivel device is significantly more robust and less sensitive to dirt and can be equipped with larger tolerances than a sliding storage head.
  • the system can be used for both round cans and rectangular cans.
