Definitions

  • the invention relates to a device for conveying and separating essentially cylindrical workpieces.
  • a conveyor system for transporting workpieces that are at least partially circular and cylindrical is known from the German patent DE 100 51 217 C2. This conveyor system shows several roller tracks for these workpieces and makes it clear that the transport of essentially cylindrical workpieces is very special and differs significantly from the transport of general bulk goods.
  • WO 2021/008646 A1 discloses a conveyor pot for a vibratory conveyor device for moving the components to be conveyed by oscillations or vibrations which act on a conveyor structure in which the components are arranged.
  • a similar system for handling bulk material along a handling line is known from the German utility model DE 20 2022 103096U1.
  • the bulk material is conveyed by means of a vibration conveyor.
  • Vibration conveying is also known for a variety of applications, for example in the wood, feed and food industries.
  • the vibration excitation is generated, for example, by unbalanced masses or thrust ball drives, which cause differently shaped conveyor units to vibrate linearly or circularly through their rotational and translational movements.
  • This form of vibration excitation results in a relative movement between the material being conveyed and the geometrically shaped conveyor unit.
  • the relative movement is often referred to as a micro-throw movement.
  • the bulk material to be conveyed can be fed to the handling section at an inlet in bulk form using a tilting device, and can be discharged individually or essentially individually at an outlet of the system.
  • the vibration conveyor for conveying the workpieces is arranged downstream of the system's inlet, which is designed as a tilting device.
  • the system shown is not suitable for the targeted handling of essentially cylindrical workpieces, in particular for conveying and possibly for separating them.
  • the invention is based on the object of specifying a device for conveying and separating essentially cylindrical workpieces which is improved compared to the prior art.
  • This device is intended to be particularly suitable for cylindrical filter elements made of fiber material, textile material, sintered material, composite material or the like, which tend to change their shape due to protrusions or adhesions or the like and thus form a non-homogeneous quantity of workpieces.
  • protrusions or Adhesions are regularly referred to as flash.
  • These cylindrical filter elements are used, for example, in the manufacture of medical test equipment.
  • the devices according to the invention are suitable for conveying and separating essentially cylindrical workpieces along a handling section which has a feed for the essentially cylindrical workpieces at its beginning, to which the workpieces can be fed in bulk.
  • a removal point is provided, from which the essentially cylindrical workpieces can be removed, in particular individually.
  • a first vibration conveyor which enables the conveying of essentially cylindrical workpieces, is arranged downstream of the feeder, whereby the first vibration conveyor has several parallel slots for receiving and conveying the essentially cylindrical workpieces.
  • the width of the slots i.e. the free width of the slots, is selected to be slightly smaller than the diameter of the essentially cylindrical workpieces.
  • the slots of the first vibration conveyor have openings in the lower area so that cylindrical workpieces with a smaller diameter than the width of the slots can be fed through these openings. can fall through openings and thus be removed from the handling section.
  • the slots can have a rectangular cross-section or a trapezoidal or tapered cross-section.
  • a first separating unit for separating the essentially cylindrical workpieces is arranged directly or indirectly downstream of the first vibrating conveyor and a second vibrating conveyor is arranged downstream of the first separating unit.
  • the second vibration conveyor has a plurality of parallel slots for receiving and conveying the essentially cylindrical workpieces, wherein the width, i.e. the free width, of the slots of the second vibration conveyor is selected to be essentially slightly larger than or equal to the diameter of the essentially cylindrical workpieces.
  • the slots of the second vibration conveyor are designed such that they are slots closed at the bottom for receiving and conveying the essentially cylindrical workpieces, whereby the receiving and conveying along the length of the slots and thus of the second vibration conveyor is very reliable.
  • the second vibration conveyor is suitable according to the first vibration conveyor and is intended to enable the conveying of essentially cylindrical workpieces, wherein it receives the individual essentially cylindrical workpieces at one end and conveys them to the other end by means of micro-throwing movements.
  • the second vibration conveyor is followed by the removal system, in which the essentially cylindrical workpieces, arranged one behind the other in a row, are made available individually for removal.
  • This design of the device according to the invention for conveying and separating essentially cylindrical workpieces along a handling path makes it possible to keep the quality of the conveyed and separated workpieces particularly high, particularly with regard to dimensional accuracy.
  • the provision of two vibration conveyors with their long, differentiated slots and the design of the separating unit with these dimensions ensures advantageous conveying reliability and, on the other hand, high quality and thus particularly pronounced dimensional accuracy of the conveyed essentially cylindrical workpieces.
  • This is of particular importance because even small deviations in size or, in particular, in shape, for example due to appendages on the workpieces, can particularly disrupt conveying and subsequent processing after the device due to these deviations.
  • These deviations occur in particular with cylindrical filter elements made of fiber material, such as those used in the manufacture of medical test equipment.
  • the proposed device thus enables particularly reliable conveying of these cylindrical filter elements made of fiber material, which act as filters.
  • the slots of the two vibration conveyors are straight or largely straight and are oriented so that they are horizontal or largely horizontal. This makes it possible for the conveying in the slots to be particularly efficient and safe, which in connection with the design of the two vibration conveyors leads to a very efficient and safe conveying in the device for the essentially cylindrical workpieces.
  • an erecting unit for deflecting the essentially cylindrical workpieces into an essentially upright position is arranged downstream of the second vibration conveyor, and the removal is arranged downstream of the erecting unit, the erecting unit making the erected workpieces arranged in a row available for removal in the removal.
  • This deflection is ensured, for example, by conveying the essentially cylindrical workpieces fed by the upstream second vibration conveyor in closed and thus covered slots in the erecting unit, these slots being provided with a transition from the horizontal to the vertical and being oriented in such a way that the transition from the slots of the second vibration conveyor to the slots of the erecting unit takes place as smoothly as possible, that is to say in particular without offset.
  • By erecting it is possible to remove the upright, cylindrical workpieces arranged in a row particularly efficiently and safely, thus preventing disruptions.
  • the first separation unit has several essentially vertically running tubes whose diameter is the same as or only slightly larger than the diameter of the essentially cylindrical workpieces and the tubes are intended to accommodate the essentially cylindrical workpieces.
  • This achieves very effective separation and, on the other hand, the dimensions enable very reliable selection of undesirable, oversized, particularly cylindrical workpieces that are too large in diameter. This makes it possible to guarantee the quality of the conveyed and separated workpieces, particularly with regard to dimensional accuracy.
  • the diameter of the tubes is preferably chosen so that it is a maximum of 10 % larger , in particular a maximum of 5 % larger than the nominal diameter of the desired cylindrical workpieces .
  • the same applies to the width of the slots which is a maximum of 10 % smaller , in particular a maximum of
  • the maximum deviation from the target diameter can be adjusted and selected depending on the quality of the workpieces. This makes it possible to keep the efficiency of the process particularly high.

  • the length of these tubes is selected such that one or a maximum of two of the cylindrical workpieces can be received without protrusion and thus transported individually and fed to a discharge in the removal area.
  • At least one cleaning unit is provided, which is intended for cleaning at least one separating unit, a deflection unit, an erecting unit and/or at least one vibration conveyor. Furthermore, it has proven particularly effective to carry out the cleaning using compressed air.
  • At least one cleaning unit has at least one compressed air nozzle which is assigned to one or a few tubes and/or one or at least a few slots and is suitable for cleaning them.
  • this device for conveying and separating workpieces is provided with at least one sensor for detecting blockages in at least one separating unit, a deflection unit, an erecting unit and/or at least one vibration conveyor.
  • This at least one sensor is connected in particular to a control for controlling at least one cleaning unit.
  • a control system for at least one cleaning unit, which enables cleaning to be carried out in a sensor-controlled and/or time-controlled manner.
  • time-controlled cleaning it is possible to keep the risk of a slot or tube becoming blocked particularly low, which is possible with little design effort and control effort in the device for conveying or separating cylindrical workpieces. This allows the efficiency of the device to be increased very efficiently.
  • At least one return line is provided for feeding essentially cylindrical workpieces removed from the handling section. Since, particularly during the separation of the first separating unit, not every cylindrical workpiece can penetrate into the tubes provided in the first separating unit and is thus rejected during the separation, which can happen due to the diameter being too large or simply by chance, the non-separated cylindrical workpieces are fed to the feeder via a return line, so that these non-separated cylindrical workpieces are fed back via the first vibration conveyor and then to the first separating unit in a kind of circulatory process until separation has been successfully carried out.
  • a preferred development of the device according to the invention shows a spiral conveyor which is provided as part of the feed. This makes it possible to ensure an advantageous continuous feed of essentially cylindrical workpieces, in particular cylindrical filters, without the space required for the feed being particularly large. This applies in particular if a return of cylindrical workpieces rejected in particular during the separation is provided.
  • This continuous feed in particular where space is limited, enables very efficient conveying and separation.
  • a bunker for the cylindrical workpieces to be conveyed is arranged upstream of the latter. From this bunker, the essentially cylindrical workpieces stored therein are fed to the spiral conveyor as required, i.e. in a discontinuous process, which then conveys the essentially cylindrical workpieces to the first vibration conveyor in a continuous process, possibly with return.
  • the dimensions of the bunker are adapted to the desired or planned throughput through the device. This makes it possible to keep the efficiency and the degree of protection of the essentially cylindrical workpieces during conveyance particularly high, especially in the case of return.

  • the common structural frame is firmly connected to the individual units and is designed in particular so that its position can be adjusted.
  • the common structural frame makes it possible to define the spatially precise allocation of the individual units on the structural frame uniformly and fixedly and thus to define the arrangement, in particular the orientation of the units to one another and thus the precise transition of the units, in particular their slots or tubes to one another.
  • the vibration conveyors of the device are particularly efficient when they are aligned in such a way that their essentially straight slots are aligned horizontally or largely horizontally and thus have no incline or at most a slight incline.
  • the second The singulation unit is designed to be laterally movable and in particular to be laterally separable from the unit upstream in the conveying direction of the handling section.
  • the bilateral mobility of the singulation unit makes it possible to move it from an active state to an inactive state and vice versa and thus to control the singulation in a targeted manner, which proves to be advantageous with regard to the removal of the separated, essentially cylindrical workpieces in the area of subsequent removal. In the inactive state, it has proven useful to carry out the removal from the singulation unit.
  • the second separating unit of which has one or more rows of tubes for separating the number of tubes in the row or rows is equal to the number of slots in the upstream erecting unit.

  • the first vibration conveyor 3 has several pa- parallel slots 31 for receiving and conveying the essentially cylindrical workpieces, the width of the slots 31 being selected such that it is slightly smaller than the diameter of the essentially cylindrical workpieces.
  • the slots 31 are open at the top and at least partially open at the bottom, so that the cylindrical workpieces fall through the slots downwards if their diameter is smaller than the target diameter of the essentially cylindrical workpieces. This is often the case with essentially cylindrical workpieces made of fiber material for filters due to the manufacturing process.
  • the cylindrical workpieces which are too small in diameter and which have fallen through the openings of the slots 31 are collected in a reject container 21 below the first vibration conveyor 3 and are thus removed from the production or conveying process.
  • the first vibration conveyor 3 is followed by a first separation unit 4 for separating the essentially cylindrical workpieces.
  • the first separation unit 4 is designed in such a way that it sorts out cylindrical workpieces with a diameter that is too large and conveys them back in the direction of the feed 2 via a return line 20 and thus feeds them through the first vibration conveyor 3 or the first separation unit 4 repeatedly or multiple times. This is of particular importance, especially when the essentially cylindrical workpieces are made of fiber material, as is used, for example, in the production of filters. With these cylindrical workpieces made of fiber material, it is very common for individual fiber overlaps to occur. Projections exceed the diameter of the structure of the cylindrical workpieces and are therefore not suitable for further processing as part of the conveying process or the separation process or for subsequent production.
  • Projections of this type can even lead to a blockage of the conveying process or the separation process or even the subsequent production process, which should be avoided if possible because these disruptions lead to considerable losses in the efficiency of the device. It has been shown that when the first vibration conveyor 3 or the first separation unit 4 is repeatedly passed through, these projections are lost and this results in sufficiently precise, essentially cylindrical workpieces, which can increase the efficiency of the device.

  • Figure 4 schematically shows a part of the device 1 in a view obliquely from above, showing the second vibration conveyor 6, followed by the erecting unit 7 and the subsequent second separating unit 8.
  • the slots 61 of the second vibration conveyor 6 are aligned horizontally and thus enable very effective transport and thus very effective conveying of the essentially cylindrical workpieces by means of micro-throwing movements in the direction of the subsequent erecting unit 7, which is provided with slots 71 corresponding to the slots 61 and which is suitable for transferring the horizontally fed cylindrical workpieces from a horizontal orientation to a vertical or essentially vertical orientation. This is done by means of appropriately curved slots 71, which in conjunction with a cover form a type of channel and safely guide the fed cylindrical workpieces in order to subsequently deliver them to the second separating unit 8.
  • the second vibration conveyor 6 and the erection unit 7 are connected to a common structural frame 30, which defines a secure assignment of these units 6, 7 to one another and enables a common adjustment, in particular with regard to the horizontal orientation of the second vibration conveyor 6 but also of the first vibration conveyor 3.
  • the second separation unit 8 has as its essential component a horizontally arranged, essentially rectangular metal plate, which can be displaced laterally as required both in the longitudinal direction 83 and in the transverse direction 83 can.
  • the rectangular metal plate has two rows of spaced-apart tubes 81 which run parallel to one another and are spaced from one another.
  • the position of the tubes 81 in a row corresponds to the vertical ends of the slots 71 of the erecting unit 7. This correspondence occurs both in terms of number and spacing and also in terms of orientation or positioning.
  • the tubes 81 have a fall-through protection 82 which is formed by a cuboid arranged beneath the rectangular plate. This limits the passage of the tubes 81 downwards so that the cylindrical workpieces inserted in the tubes 81 cannot fall through. This enables the cylindrical workpieces to be separated.
  • the two rows are filled one behind the other using the cylindrical workpieces, which is accompanied by a corresponding separation, and then moved out of the area of the vertical ends of the slots 71 by displacement in a lateral direction of movement 83 so that these are closed and the filled tubes 81 are brought into a removal position 9.
  • the separated, selected and conveyed essentially cylindrical workpieces are removed from the device 1 and fed to a further production process.
  • the two-stage design of the device 1 for conveying, separating and selecting the essentially cylindrical workpieces makes it possible to keep production reliability and conveying quality particularly high since, on the one hand, in a first step the quality of the cylindrical workpieces conveyed to the end is ensured and, on the other hand, in a second process the quantity of conveyed, separated and selected workpieces is made evenly high.
  • the device 1 shown therefore proves to be particularly advantageous and in particular very robust with regard to possible malfunctions caused by contamination or by deviations in the shape or size, in particular by lint attached to cylindrical workpieces made of fibrous material, as is very frequently used in the medical environment, especially for test equipment.
