Definitions

  • the invention relates to a system for pressing fiber cement slabs, which first lie in the form of a fiber cement mat in the middle on a press base with symmetrically arranged, lateral manipulation surfaces between them and into a press point of a press and then as pressed plates on the press base from the press point can be transported by means of a transport device.
  • a prefabricated fiber cement mat is transferred to a delivered press base.
  • the loaded underlay is transported to a press in a pressing point and, positioned there, pressed with the mat.
  • the base with the pressed plate is transported out of the pressing point.
  • the plate is then removed from the base and the empty base is transported back to the start of the system in order to be loaded again with a fiber cement mat to be pressed.
  • a number of the press pads circulate in the process at a speed of, for example, 3 m / sec and in a sequence of, for example, 12 seconds.
  • tilting or slipping of the press documents to be transported is to be avoided, thereby ensuring their exact positioning in the individual treatment or manipulation stations without bruising.
  • the transport device should be relatively simple and also applicable for systems with presses with two pressing points arranged one above the other.
  • the transport device in order to accommodate the pressing pads with the plates, has two conveyor belts running parallel to one another along the pressing point, the relative spacing and width of which is the distance and the width of the manipulation surfaces of the pressing pads, which are exposed on the belts for transport come, correspond to which tapes, both of the same length, are provided with their length in a regular spaced succession to the tape, fixed engagement points, to which tapes a drive device is assigned, which has engagement points designed for engaging the engagement points, the drive device to synchronous movement of the two belts, ie at the same speed at the same time.
  • the conveyor belts are designed as toothed belts, the regularly arranged teeth of which form the engagement points, the pitch and tooth shape of the toothed belts being provided in accordance with toothed drive gearwheels which form the engagement elements of the drive device.
  • timing belts are available on the market and the transport device equipped with them works reliably and practically maintenance-free.
  • the system shown in FIG. 1 is used to press fiber cement boards 1.
  • fiber cement boards 1 First, in the form of a fiber cement mat, these are, as shown in FIG. 2, on a press base 2 which has lateral manipulation surfaces 3 arranged symmetrically in parallel.
  • the plate 1 thus lies between the manipulation surfaces 3.
  • the base 2 is perforated in the area covered by the plate 1, for removing the liquid to be pressed out of the mat during pressing.
  • the underlay 2 is corrugated in this area.
  • the M anipulations vom 3 are each planar and lie in the same plane.
  • the base 2 with the plate 1 is transported into a pressing point 4 of a press 5 and after the pressing, when the plate 1 has been pressed, the base 2 with the plate 1 transported out of the pressing point 4.
  • the pressing point is formed by pressing stamps 7, which cover the format of the plate 1, so that the manipulation surfaces 3 of the base 2 lie outside and parallel along the pressing point when the plate 1 with the base 2 is positioned in the pressing point 4.
  • the transport device 6 has two conveyor belts 8. They run parallel to each other along the pressing point 4 through the press 5.
  • the distance between the belts 8 and their width correspond to the relative distance and the width of the manipulation surfaces 3 of the press pads 2.
  • the spacing between successive engagement points 9 which are fixed to the belt 8 is provided.
  • a drive device 10 is assigned to these conveyor belts 8, which has engagement elements 11 which are designed corresponding to the engagement points 9 and engage in the engagement points.
  • the drive device 10 is designed to move the belts 8 synchronously. It thus serves to move the belts 8 at the same speed and at the same time.
  • the conveyor belts are designed as toothed belts 8, the teeth 9 of which are regularly arranged in length and form the engagement points.
  • the drive device 10 has a drive gear 11 assigned to each toothed belt 8, which is toothed according to the pitch and tooth shape of the toothed belt 8 and forms the mentioned engagement element.
  • only one side of the toothed belt 8 is toothed and the other side is smooth. It can be seen that the toothed belt 8, with its toothed side, faces a press base 2 to be transported, which is transported exposed on the toothed belt 8.
  • the toothed belt 8 is guided by means of two deflection rollers 12, so that it forms a loop around the drive toothed wheel 11. There is a loop in the range of 180 °.
  • the deflection rollers 12 serve as tension rollers for the toothed belt 8.
  • a toothed belt made of reinforced plastic is best suited for this transport device. Its smooth side should have good sliding properties compared to a guide pad 13, which is provided for its guidance and is made of plastic, for example. Such a timing belt is available on the market. It is also conceivable to use a liquid film, e.g. to provide a hydrostatically constructed liquid layer between the toothed belt 8 and the guide pad 13 in order to achieve wear-free conditions in the present case.
  • the two toothed belts 8 move absolutely synchronously and conformally. This means that there is no relative instantaneous displacement of one toothed belt relative to the other in the pair.
  • the relatively heavy press pad 2 with the plate 1 is free but non-slipping on the toothed belt and cannot be shifted and / or tilted due to the momentary delay or advance of one belt relative to the other and can thus be positioned exactly at a desired point on the transport route.
  • the surfaces of the conveyor belts 8 and the manipulation surfaces 3 of the press pads 2 facing or coming into contact with one another are to be provided with a non-slip surface in the case of the toothed belt only for the manipulation surfaces . Then a non-slip fit of the press pad on the belts is safely achieved.
  • the transport device 6 is divided into three sections: a section 6 1 , which leads through the press 5, is preceded by a section 6 2 , which serves as a waiting station , and a section 6 3 downstream, which serves as a parking station.
  • Each of the three sections 6 1 , 6 2 , 6 3 has a pair of conveyor belts 8 1 , 8 2 , 8 3 in its area.
  • Each pair is separated from the other in terms of drive and is equipped with its own, specifically commanded and adjustable drive device 10 1 , 10 2 , 10 3 . Every drive forward direction is driven by its own, specially commanded and adjustable DC motor M.
  • the system shown in Figure 1 is equipped with a press 5 with two pressing points 4 1 and 4 2 arranged one above the other.
  • This press presses two plates at once in one work cycle.
  • Each of the pressing points 4 1 and 4 2 is assigned a transport device 6.
  • the transport of the press documents 2 with the plates 1 takes place simultaneously in the same cycle in a lower and in an upper floor.
  • the upper floor is shown in dashed lines in the drawing.
  • Prefabricated fiber cement mats are placed on the press pads in a charging station 14.
  • the pad lies on a conveyor belt 15 of the station and waits there until the mat is put on.
  • the finished pressed fiber cement boards are removed from the press documents into a removal station 16, on the left in the picture, lying on a conveyor belt 17 of the station.
  • the conveyor belts 15 and 17 of the loading and unloading stations are at the level of the lower transport floor mentioned above.
  • Every second loaded press pad coming from the charging station is raised from the level of the lower level to the level of the above-mentioned upper level and, after pressing, is lowered to the level of the lower level. This happens in the area of the waiting station 6 2 or in the area of the parking station 6 3 .
  • a waiting or parking station for this purpose is shown in more detail in FIG. 3.
  • the conveyor belts 8 of the upper floor are arranged on a frame 20 so as to be laterally displaceable, so that the relative distance between the belts can be increased over the width of the press base. If the tapes are in this spread position, the press pad can be transported between them in the vertical direction.
  • This vertical transport is provided by a lifting table with a horizontal table top 21, which can be moved by means of a lifting device 22 into an upper position above the level of the upper level and into a lower position below the level of the lower level.
  • the base After simultaneous movement of the belts 15 and the adjoining belts 8 2 , the base is positioned in the waiting station 6 2 on the lower belts 8 2 .
  • the table top 21 is in its lower position.
  • the upper conveyor belts of the waiting station 6 2 are spread and are in the position shown at the top right in FIG. 3, so that the underlay can be transported between them.
  • the table top 21 moves to its upper position and lifts the support above the level of the upper floor.
  • the upper bands return and are below the manipulation areas of the underlay. This position can be seen in the top left of Figure 3.
  • the table top 21 returns to its lower position and the first mat comes to rest on the upper belts.
  • a second, meanwhile loaded document comes to the lower level of the waiting station 6 2 .
  • the pressing points 4 1 and 4 2 of the press 5 open.
  • the first and the second loaded underlay are positioned in the relevant pressing points.
  • the pressing process is completed and the pressing points 4 1 and 4 2 are opened.
  • the first and the second support are simultaneously moved into the parking statutes 6 3 and positioned there.
  • the belts 8 2 and 8 1 on the two floors transport the next two waiting documents to the pressing points 4 1 and 4 2 .
  • the underlay located on the lower level is moved into the unloading station 16 by simultaneously moving the lower belts 8 3 and the adjoining belts 17 and the pressed plate is removed from the underlay.
  • the empty pad is transported back to the charging station 14 via a transport path.
  • the table top 21 in the parking station 6 3 goes into its upper position and thus lifts the surface previously lying on the upper belts.
  • the upper belts return to their closer position and are thus ready to take over another press pad.
  • the base which has been converted from top to bottom is inserted into the unloading station drive and after removal of the fiber cement board, the empty base is transported back to the charging station 14 via the above-mentioned transport route.
  • the system works continuously and the described transport of the documents is regulated in accordance with the cycle of the press 5.
  • the loading and unloading of the documents takes place in stations 14 and 16 in half a cycle.
  • the transfer of every second document from one floor to the other in stations 6 2 and 6 3 also takes place within the period of half a cycle.
  • the transport devices in stations 14 and 16, i.e. the conveyor belts 15 and 17 and the drive devices 18 and 19 are also designed in accordance with the described invention. With the same means, the return of the empty documents can be solved.
