Definitions

  • valve bags are used for cement and similar bulk goods used, the filling openings with a filling valve are equipped, which is under the pressure of the contained in the sack Guts closes. Special measures for closing the bags are therefore usually unnecessary. However, can Filling valves prevent small quantities of fine filling from escaping do not prevent. There is therefore a desire to have valve bags to be closed by a welding process.
  • the invention requires that the bags be filled continuously rotating carousel is used on the a plurality of filling devices is arranged, each of which a sack holder and a filler neck is assigned.
  • a filling device runs at a plug-on station over, a sack to be filled is opened with its opening the filler neck. Then the sack is filled, while being held by the bag holder. Finally he reaches a dropping station, in which the filled sack one Hand over the conveyor to remove the filled sacks becomes. If you want to close the bags before dropping them, you have to to provide welding equipment on the filling carousel. Since the Welding equipment is expensive, it is disadvantageous to everyone individual filling device of the filling carousel with a Equip welding equipment.
  • the solution is that one or more welding devices on a separate Circulation conveyor, preferably a welding carousel, are arranged, which is arranged approximately tangentially to the filling carousel and for the radial withdrawal of the bags from the filling carousel is set up.
  • the welding device should have no or the least possible changes on the filling carousel, with proven Constructions a radial arrangement of the filler neck and Has bag holders; i.e. that the filler neck and mounting surfaces are designed so that they are approximately radial Require insertion and removal movement of the bags. Only in Tangent point of the orbits of the interacting carousels their radii are aligned. It is therefore conceivable that one of the bag holders of the filling machine requested, for example, radial transfer movement at short notice around the tangent point of the two carousels leaves. This is possible, for example, in that At this point, a slider removes the sack concerned the holder of the filling carousel slides over into a holder of the welding carousel.
  • the invention is such Solution does not exclude, it pulls a transfer movement that accelerates slowly and therefore slowly. This can be done by essentially sacking the bags tangential run from the filling carousel to the welding carousel pass. Such a takeover movement takes a certain one Arch distance in claim. Therefore can not be expected that the radius direction of the receiving bag holder over the entire length of this arch so far with the Radius direction matches how this is the filler neck and request the bag holder of the filling carousel.
  • This problem solves the invention in that the bag holders of the Welding carousels around an axis parallel to the carousel axis are pivotable.
  • the separation of the bags from the Bag holders of the filling carousel can be done simply by that the arcs on which the bag holders of both Move carousels after their tangent point, move apart. During this divergence, the held by the bag holder of the welding carousel Pull the sack out of the sack holder of the filling carousel.
  • the radius of the circle of the welding carousel on which the pivot axes of its bag holders lie is less than the radius of its Sack arch of the filling carousel tangent arch.
  • the pivot axis of each bag holder is not middle in the area in which the sack to be held is but closer to the center of rotation of the welding carousel.
  • the bag holders of the welding carousel are expediently of pliers clamping the bags in the circumferential direction educated. Before picking up a sack, they approach the relevant holder of the filling carousel in the open state and then grab the sack on both sides. The latter happens expediently at the tangent point at which the two sides meet Orbits come closest. Strictly necessary but it is not. Following the point in which the bag holders of the welding carousel are one Sack closed, they pull the gripped sack from the bag holder of the filling carousel because of the diverging the double-sided letterhead.
  • the bag holders lead on the welding carousel after grabbing a sack an inward swing through which the gripped sack closer to the axis of rotation of the welding carousel.
  • This Inward swiveling inevitably results in part, namely on the one hand by aligning the bag holder of the Welding carousels on the changing orientation relative to it the associated bag holder of the filling carousel, and on the other hand, because the welding carousel runs in opposite directions to the sack holder.
  • This relative movement can be used to attach the bag to the welding device to close it. Because the relative rotation mainly on the movement of the carousel and only to a lesser extent Dimension is based on the rotation of the bag holder the gripped sack no significant acceleration exposed to the location and condition of his could adversely change the weld.
  • valve sacks Although the invention is primarily for use with Valve sacks, it is also used for other sacks, that do not contain a filling valve, can be used.
  • the filling and welding carousel can run at a constant speed operate.
  • the invention therefore includes for cases particularly high demands on the radial withdrawal of the bags from Filling carousel the proposal, the relative speed of the Vary carousels during withdrawal so that a bag holder of the welding carousel on the radius of the interacting with it Bag holder of the filling carousel aligned remains.
  • the rotational speed is expediently of the welding carousel varies while that Filling carousel revolves constantly. You can also use the welding carousel let it circulate constantly and the sack holder on it move periodically in the circumferential direction.
  • the filling carousel 1 has eight evenly distributed around the circumference Filling devices 2, three of which are shown.
  • the Filling carousel turns in at constant speed Arrow direction 3 around the axis of rotation 9.
  • Each filling device has a filler neck 4, which is aligned approximately radially and to a hopper 5 or the like for feeding of the bulk goods to be filled is connected.
  • the filling device has a bag holder 6 which a suitable carrier 7 is held and for example by two V-shaped sheets arranged to each other is formed.
  • the shape, arrangement and function of these bag holders is is known and therefore needs no further description here.
  • the bag holder 6 is in a known manner with a weighing device connected to the filling weight of the sack during the Control the filling process.
  • the bag holders 6 of the filling carousel 1 move during the carousel rotation on a circular arc 10 (sack arc).
  • the sheets forming the bag holder form for the floor or lower edge of the dot-dash line indicated at 8 Sacks a radial guide. From this The sack can only be guided in essentially once it has been filled radial direction. It is also therefore necessary because the filler neck 4 radially into the Filling opening of the sack 8 protrudes.
  • There may be orders in which the bag holder 6 and the nozzle 4 are formed in this way are that the filled sacks also in a different than can be taken from the radial direction. For these cases the explanation of the invention applies in an analogous manner.
  • the filling carousel 1 is a feed conveyor 11 for filling Sacks 8 upstream of this in the initially lying position and then in a vertical position Filling devices 2 of the filling carousel 1 supplies. Always then, when a free filling device 2 runs past the conveyor 11, a sack to be filled is shot onto the filler neck 4, to get filled during the rotation of the carousel become. After filling is complete, it reaches the transfer station 12, in which it is handed over to the welding carousel 13.
  • the welding carousel has a center column 15, which at 16 rotatably mounted about its vertical axis 18 and by means of a Motor 17 driven at a constant rotational speed becomes. It carries rigid support arms 19, which in the end are vertical Form pivot bearing 20.
  • a carrier 23 is arranged thereon. On a part 21 rotatably connected to the carrier 23 a roller 24 is provided, which has a control cam 25 interacts and the respective angle setting of the wearer 23 determined in relation to the radius direction.
  • the carrier 23 carries two gripper axes 27, which are parallel to the pivot bearing 20th run. They are equidistant from the pivot bearing 20.
  • the gripper plates 28 can be designed as suction plates that adhere to the surface of the bag due to negative pressure. Thereby is a secure grip even with little or no Clamping force guaranteed.
  • Each bag holder 28 of the welding carousel is one Assigned welding device 30, which is preferably stationary is arranged on the welding carousel.
  • the one to be welded Opening 29 of sack 8 reaches welding device 30 by that the bag holder 28 with the associated carrier 23rd is rotated about the pivot axis 20 in the direction of arrow 31. in the example shown, the angle of rotation is about 90 °.
  • a discharge conveyor 33 is arranged on which the filled and sealed bags 8 are dropped. So that she have the desired orientation there, they are suitable pivoting movement of the bag holder 28 with the carrier 23 in the direction of arrow 34 (FIG. 1) into the desired position rotated before the bag holder opens.
  • the sack 8 to be pulled off has and the associated bag holder 6 of the filling carousel already far apart from each other.
  • the opened bag holder 28 is symmetrical again to the direction of radius 36 to focus on sensing of a new sack in the transfer position 12 according to Prepare Fig. 1.
