Definitions

  • the invention relates to a method for transporting the molding box consisting of the upper box and the lower box in a foundry molding system with two parallel transport tracks, one molding machine each for the upper box and the lower box on one of the two transport tracks and transfer stations for moving the upper box and the lower box from one to the other conveyor.
  • the invention relates to molding systems for box casting, in which a part of the mold is molded in a lower box and an upper box, usually by compacting molding sand over a corresponding model.
  • the upper box and lower box are molded separately and - usually after inserting cores in the lower box - added to form the casting mold.
  • Molding plants of high performance have two molding machines. In one the upper box shape, in the other the lower box shape. Nevertheless, with the known molding plants, the high hourly output of modern molding machines, which is possible per se, cannot be exploited, or can only be exploited with considerable design effort in the area of the transport devices.
  • Known molding plants of the structure mentioned at the outset have two transport tracks, the molding machines for the upper box and lower box being arranged one behind the other at one of the two transport tracks in the transport direction.
  • the empty molding box consisting of upper box and lower box is fed to a translation device on a first transport path, which is usually designed as a pallet path.
  • the translator has two box positions one behind the other and bridges the distance to the second transport path which is passed through the two molding machines.
  • the translation device is designed as a double device and takes over the upper box and, at a lower level, the lower box and moves both parts of the box simultaneously to two empty spaces on the second transport path.
  • the lower box and the upper box are fed one behind the other on the second transport track by means of a pusher drive to the molding machines one behind the other.
  • the feed drive on the second transport path must overcome a transport path with every work cycle that is twice the size of a box in the transport direction corresponds.
  • This Transport route can reach more than three meters with large box division.
  • the feed drive usually a hydraulic cylinder, is therefore to be designed accordingly in a complex manner. Considerable acceleration and deceleration forces must also be mastered.
  • a substantially simpler thrust drive can be selected for the first transport path, since it only has to overcome half the transport path.
  • the lower box is molded on the first molding machine in the transport direction and the upper box on the second molding machine.
  • the top box and bottom box then go into a second translation device, which resets the molded top box back onto the first transport path, while the molded bottom box on the second transport path reaches the subsequent core insertion path.
  • the molded upper box is moved on the first transport path parallel to the core insertion section. Because of this transport principle, the work cycle behind the second translator must be shortened to half the transport route. This initially requires a braking device acting against the thrust drive and a further drive in the core insertion section, as well as a further braking device to be provided at the end of the core insertion section.
  • a funnel drilling device for producing the bores for the casting funnel, risers, ventilation openings, etc. is arranged in the top box shape on the first transport path behind the second translating device.
  • the available machine time is shortened by approximately half the time required for the transport route required for two box parts in the second transport path. They are not only the drives for the crates in the second transport path are complex and functionally sensitive, but the two translators are also different, in particular the first translator for the top box and bottom box is very expensive. Finally, the pallets on the first transport path between the two translators run empty, so that unnecessary drive energy is consumed in the first transport path.
  • the invention is based on the object of proposing a transport method and a molding system which allows full utilization of the machine power, the molding system also being to be simplified in terms of construction and function.
  • the object of the invention is achieved in that at the first translation station in the direction of transport, the upper box (OK) of the empty molding box fed on the first transport path is separated from the lower box (UK) and only he (OK) is separated from the second
  • the conveyor belt is transferred with the two molding machines and fed to the first molding machine, while the empty lower box (UK) moves on the first transport to the second translation station arranged between the molding machines and to an empty space immediately in front of the first molded upper box coming out of the molding machine (OK ) is transferred on the second transport path, and the first molded upper box (OK) is moved to the translation station in the next work cycle and transferred to the previously occupied empty space on the first transport path and moved there, while the lower box (UK) moves to the second Molding machine and then moved to the core insertion section, with upper box (OK) and Lower box (UK) can be moved on the two transport tracks with an offset transport cycle at the same cycle length, which corresponds to the mold box dimension in the transport direction.
  • the method proposed according to the invention treads a completely new path compared to the prior art, in that the upper box is transported on a first section of the first transport path, namely between the two translators, the lower box, on the parallel section of the second conveyor path, the upper box in the first molding machine is molded.
  • the top box and bottom box then change the transport tracks by moving the molded top box back to the first transport track, transferring the empty bottom box to the second transport track and transporting it to the second molding machine for molding.
  • the lower box and upper box therefore make a complete change of lane.
  • This transport principle makes it possible to work on the second transport path with the molding machines with a simple feed, ie the top boxes moved there to the first section are shifted by only one haste length with each work cycle.
  • the lower boxes on the first section of the first transport path and the upper boxes on the second section of each are only moved by one haste length per work cycle.
  • only simple feed drives with a short stroke length are required.
  • the main advantage is that the shortest possible transport stroke for a given box length means that the performance of the molding machines can be used in the best possible way. Also there is no reduction of the transport route from a double stroke to a simple transport stroke.
  • an equal number of box places is provided between the two translation stations and that an upper box (OK) of the first one is emptied when the molding system is started up on or before the first translation station Form box is discarded or only an empty upper box or an empty lower box is provided.
  • the offset work cycle on both transport lanes ensures that the empty space on one of the two transport tracks in the area of the second translation station is always maintained.
  • the mold in the upper box (OK) is provided with bores for the casting funnel and / or riser and / or ventilation openings behind the first molding machine and from the second transfer station.
  • the reworking of the first molded upper box can be carried out in front of the second molding machine for the lower box, so that the molding sand obtained there can be easily removed by means of the conveyor, which is different from the molding machine for the lower box via the molding machine for the upper box extends and takes away the molding sand accumulating there.
  • the invention is based on a foundry molding system for box casting, consisting of two parallel transport tracks with pusher drives, two molding machines arranged along a transport track, two translation devices for moving the upper box (OK) or lower box (UK) from one to the other transport path, of which the translating device arranged in front of the first molding machine in the transport direction separates the upper box (OK) from the molding box fed empty on the first transport path and feeds it to the second transport path with the molding machines, and a core insertion path for the molded lower box connected to this transport path ( UK), behind the top box and bottom box.
  • a foundry molding system for box casting consisting of two parallel transport tracks with pusher drives, two molding machines arranged along a transport track, two translation devices for moving the upper box (OK) or lower box (UK) from one to the other transport path, of which the translating device arranged in front of the first molding machine in the transport direction separates the upper box (OK) from the molding box fed empty on the first transport path and feeds it to the second transport path with the molding machines,
  • This known molding system is characterized according to the invention in that the first molding machine for Impression of the upper box (OK) and the second molding machine for molding the lower box (UK) is set up, and that the second translation device is arranged between the two molding machines and in a first route the empty lower box arriving on the first transport path to an empty space immediately in front of the transfers the first molded upper box (OK) on the second transport path for the transport to the second molding machine and, after a further transport cycle, translates the molded upper box that has entered the translation station on the way back to the first transport path, and that the thrust drives for the first and second transport paths move the top box and bottom box one box length at a time.
  • the translator can move the molded upper box to an empty space on the first transport path on the first route and an empty lower box to the second transport path on the way back.
  • the linear actuators only have to cover a distance that corresponds to the box length measured in the transport direction. This reduces the design effort.
  • the two translation devices can have a simpler structure.
  • the second translating device is optimally used because it carries out a translating process on the way there and back.
  • only one braking device is required at the end of the core insertion section, which counteracts the thrust drive of the second transport path. Due to the less complex and fewer drives, there are corresponding cost savings.
  • the control technology can be simplified accordingly.
  • the first transport path is a pallet path and the second transport path is a roller conveyor, and that the translation devices have grippers which engage under the upper box or lower box by means of rollers.
  • rollers on the gripper-like translating device are designed such that they are aligned with the roller conveyor provided there in the second transport path.
  • the design of the molding system according to the invention enables a funnel drilling device to be arranged between the first molding machine and the second translating device.
  • Thrust drives preferably hydraulic cylinders, whose working stroke corresponds to the mold box dimension in the transport direction serve as the transport drive for both transport tracks.
  • a braking device which counteracts the thrust drives and which ensures that the fasteners keep contact with one another on each transport path.
  • the invention is based on an exemplary embodiment shown schematically in the drawing of the molding plant explained.
  • the molding system shown in the drawing has two parallel transport tracks 1, 2, each of which is assigned a linear actuator 3 or 4 and at the end a braking device or 6.
  • the second transport path passes through two molding machines 7 and 8, which have a filling vessel 10 and a compression unit 11 on a shuttle 9 running in or against the transport direction.
  • a number of model plates 12 are arranged on a carrier, possibly again on a shuttle, which can optionally be moved into the molding machine.
  • a translating device 13 or 14 is arranged, which bridges the distance between the two transport tracks 1, 2.
  • the empty molding box 15 composed of the upper box and lower box are conveyed up on the transport path 1 by means of the linear drive 3 and reach the translating device 13.
  • There the upper box OK is removed and transferred to the transport path 2, while the lower box UK remains on the transport path 1.
  • the upper box OK is transported by means of the thrust drive 4 on the transport path 2 into the molding machine 7, filled with molding sand there and the sand filling compacted over the model.
  • the molded upper box finally arrives at a funnel drilling machine in front of the second translating device 14 and then into a turning device 16, in which it is turned by 180 °.
  • On the conveyor track 2 is in the translator 14 first an empty space.
  • An empty lower box is transferred to this empty space by the conveyor track 1 by means of the translation device 14.
  • the molded upper box which has arrived directly in front of the translating device 14, arrives in the translating device and, when it returns, is transferred to the then empty space on the first transport path 1, which the lower box had previously occupied.
  • the sub-box which is clocked further by one box position, finally arrives in the molding machine 8, is filled there with molding sand from the filling vessel 10 and this is compacted above the model by means of the compacting device 11.
  • the molded lower box UK arrives behind the molding machine 8 in a turning device 17 and then on a core insertion section on the transport track 2, while at the same time the molded upper box is clocked further on the parallel section of the transport track 1.
  • the lower box and upper box are kept in contact by means of the braking devices 5, 6, which counteract the linear actuators in 3, 4.
  • the upper and lower boxes are put together behind the core insertion section and the completed molded box is brought to the casting section.
  • both transport tracks 1, 2 which only have to overcome the minimally necessary transport path, namely the box length, per work cycle.
  • the translation devices 13 and 14 can be of the simplest design, and that the performance of the translation device 14 can also be optimally utilized by translating a box each way there and back. Furthermore, all sections of both transport tracks 1, 2 are covered with boxes, so that the drive or braking energy is used in the best possible way.
