DE1930171B1 - Device for placing or removing clay moldings on a roof tile revolver press - Google Patents

Description

The invention relates to a device for the task or removal of clay moldings on a Roof tile revolver press with at least two compression molds, which have a specific, given lateral Have a spacing, while the briquettes and support frames conveyed in and out are tight lie against each other, each of which is picked up from a base by a lifter assigned to each form, to be offset laterally and stored by the dimension to be offset.

The transfer of clay moldings from one side to another is done with crank relocators carried out. These have the disadvantage that they are heavy and space consuming and a Have a number of bearing and sliding surfaces that require constant maintenance. It is also disadvantageous that the transfer is carried out in a combined vertical and horizontal movement, so that the clay cakes were picked up by dragging from their base and then dragged on again be dropped off; be discontinued; be deducted; be dismissed. This is for clay moldings with a high water content, as it is for high-quality, Flat roof tiles are required, disadvantageous because these are relatively soft and by the Grinding movement can be damaged.

It is therefore the object of the invention to provide a light and simple transfer device in which the grinding of the clay moldings on their base when they are lifted and placed is excluded. Furthermore, the transfer device should be less prone to failure and low maintenance. With the device It should also be possible to use finished pressed roof tiles or the like from those located at a distance Remove molds from the turret press and lined up closely for the following drying forward.

This object is achieved according to the invention in a device of the type described above solved that a vertically adjustable, substantially horizontal guide frame is provided on which the jacks can be moved by the amount to be moved, and that fixed to the guide frame connected, acting with their free ends on the lifters adjusting means are arranged which the Lifters on the guide frame between positions with different spacing dimensions only then move if the level of the jack differs from that of the base.

It can thus be achieved that with a certain lateral distance, mostly directly next to each other in several parallel rows arriving clay cakes through the elevator first lifted vertically from a roller chair, then moved apart laterally to the new distance and then placed back on the roller chair in a vertical lowering movement, after which the jacks are moved back to their original position, so that they are for a new one Work cycle ready.

On the other hand, it is possible to feed side by side on the removal side of a revolver press To raise the support frame, to drive to the required distance under the molds and after the bricks have been picked up from the press molds, the frames for forwarding on transport routes lower and collapse.

The guide frame preferably has a pair of rails and as control means for lifting and lowering the pair of rails is a unilaterally fixedly supported piston-cylinder drive, which engages with its piston rod on the pair of rails via levers which are also pivotally mounted in a stationary manner. The levers can consist of two identical ones, connected to one another by a link on their first lever arms Be formed angle levers which are fixedly mounted in their vertices and with the engage the second lever arms at two points on the guide frame near the ends of the pair of rails.

The angle levers preferably each have a pair of levers connected to one another by an axis lever arms arranged in parallel that engage the rails of the pair of rails.

Through these embodiments it is achieved that the starting from a single drive Force is evenly distributed on the pair of rails, so that this is lifted exactly vertically, what

ao means that the clay cakes are so careful when shifting sideways despite the high working speed treated as possible.

It is useful if sliding slots in the lever arms of the angle lever that act on the guide frame, Sliding pins on the guide frame that engage in the sliding slots, and a vertical guide of the Are arranged guide frame.

The actuating means for moving the jacks are advantageously made up of piston-cylinder drives formed that automatically return to their original position.

If more than two adjacent briquettes are to be moved, this can be done by doing this happen that the actuator of the actuating means at the first lifter located away from its fixed point attacks and a sliding guide is provided on the closer second lifter through which one on first lifter attached tie rod with limit stop is passed.

Preferably, the stop is on the spacing the shapes of the turret press adjustable.

This arrangement makes it possible to simultaneously pull out two jacks by means of a shifting unit a first position, in which both are close together, to move into a second position, in which both lifters also have a different distance from one another. The number of needed Piston-cylinder drives are thus kept small, so that the entire arrangement is cheap.

In addition, if an adjustable stop is provided, the turnover device can move slightly Adjust the changed spacing dimensions by changing the shapes in the assigned Turret press are conditional.

The device can be designed so that a two-armed lever is attached in the guide frame is, the pivotable about a vertical axis and attached to the lever arms with the handlebars Is connected to lifters.

If there is more than one jack on either side of the pivot point of the two-armed lever, so the lifter located away from the fulcrum can be attached to the extreme ends of the lever arms, the closer located lifter be hinged to further inward sections of the lever arms.

The drive of the two-armed lever is expediently mechanical or pneumatic or hydraulic actuated.

By extending and retracting the piston rods of the drives 39 α, 39 &, the lift trucks 36 a, 36 d are moved into their two extreme displacement positions (FIGS. 2 and 3). The resetting can take place by spring force or by acting on the piston from the second side.

In order to be able to move the internal lift trucks 36 b, 36 c from the narrow position into the wide delivery position for the clay cakes, the lift trucks 36 b, 36 c slide guides 42 b, 42 c through which tie rods 43 are guided are, which are attached to the outer lift truck 36 a, 36 d . Adjustable stops 44 near the end of the tie rods 43 ensure that when the lift trucks 36 a, 36 d move apart by means of the drives 39 α, 39 & the internal lift trucks 36 b, 36 c are moved outwards when the outer lift trucks 36 a , 36 d by the distance by which they are apart in the extended position (FIG. 3). In this way, the inner lift trucks 36b, 36c also reach the desired spacing.

The inner lift trucks 36 b, 36 c are moved back to their starting position by the outer lift trucks, which are each connected to the piston rod of the drive 39 a and 39 b , come up against them and move them back.

The timing of the relocating process is as follows: The clay cakes 20 α to 20d, which have passed through the cutting wires 17 and are on the roller chair 18 via the lift truck 36 a to 36 d , are initially raised above the level of the rollers by the fact that the drive 31 is fed with a pressure medium and thereby lifts the guide frame 34. Subsequent to this lifting movement, the drives 39 a, 39 & receive pressure medium supply, so that first the outer lifting trucks 36 a, 36 d and after driving a certain distance also the inner lifting trucks 36 b, 36 c due to the coupling with the tie rods 43 to the outside be moved to the delivery distance. Then the pressure medium supply to the drive 31 is interrupted so that the entire guide frame 34 lowers, which has the consequence that the clay cakes 20a to 20a "come to rest on the rollers 19 of the roller chair in the disengaged position. At this moment can the second transport of the clay cakes to the turret press takes place, while at the same time the pressure medium supply to the drives 39 α, 39 b is interrupted so that the lift trucks, whose lifters are below the level of the rollers 19, return to their starting position start all over again.

F i g. 5 shows a further exemplary embodiment, with the device on the delivery side of the turret press 50 is provided. The individual press molds 51 lying next to one another of the turret press have a certain distance to each other. The ready-pressed bricks must be taken from the removal device be included in the distance between the molds of the turret press. This distance S-measure is indicated by the brick 52 'shown in dash-dotted lines. The support frame 53, on which the bricks 52 are picked up and transported away, come close together in the Recording device, which is designated as a whole with 54. The device must therefore be immediate Take up adjacent support frames 53, lift them and adjust to the required distance the brick press molds 51 move apart, in this position the bricks 52 on the Pick up frames 53, lower the frames 53 again and return them to

ίο move together positions that are close to one another and finally place the frames 53 on a transport device which they in the form shown in FIG. 6th and 7 transported away in the direction indicated by an arrow.

According to FIG. 5, the device 54 has a stationarily attached in the frame 55 of the transport device Piston-cylinder drive 56, which with its piston rod 57 on an angle lever 58 attacks, the fulcrum of which is also mounted in a stationary manner in the rack frame 55. The bell crank 58 is connected to the same angle lever 59 by a handlebar 60, so that the also on the frame 55 fixedly mounted second angle lever 59 performs the same angular movement as the angle lever 58. With their second lever arms, which have a longitudinal slot 60 and 61, the overlap Angle levers 58 and 59 slide pins 62, 63 which are fastened to a guide frame 64 that can be raised and lowered in the frame 55. This guide frame 64 is guided vertically in the frame 55. By pivoting the angle levers 58 and 59 with the aid of the drive 56, the pins 62 and 63 slide in the slots 60 and 61 so that the guide frame 64 has a and move down.

A lever 65 is rotatably mounted about a vertical shaft 66 in the guide frame 64. This lever 65 is shown in plan view in FIGS. 6 and 7 shown. It can be rotated about its central axis by adjusting means 67.

In the guide frame 64 there are guide rails 68 on which jacks 69 with sliders, rollers or the like 70 are guided. The lifters 69 can be moved together into the narrowest position in which they touch one another (see FIG. 6), or they can be moved apart, as shown in FIG. 7.

In order to achieve this displacement movement of the lifters 69 on the guide rails 68, the individual Lifter with lever 65 through handlebar 71, 71 '

Connected in such a way that when the rotary lever 65 is rotated about its central axis, the lifter 69 is displaced will.

In order to achieve a different displacement of the individual jacks, they are the pivot point 66 most distant lifters 69 hinged to the outer portions of the lever arms, while the jacks 69 located further inside are articulated at points of the lever arms of the lever 65, which are closer to its axis of rotation.

The removal device 54 now interacts with the turret press 50 in the following way: On the transport path 55 are by means of rollers or tapes on acquisition ähmchen 53 up to a stop 72 advanced. The jacks 69 are in their narrowest position at this point in time. The drive 56 now lifts the guide frame 64 so that the frames 53 are lifted over the transport path 55 are, and at the same time issued the actuating means 67 to the

Lever 65 a rotary movement, so that the lifters 69 via the links 71, 71 'on the guide rails 68 to be moved. The rotation of the lever 65 is stopped when the jack 69 is accurate driven under the mold 51 of the turret press 50 are. At this point in time, the highest position of the guide frame 64 is reached, so that the pressed moldings 52 can be placed on the frames 53.

By reversing the movement process just described the frames are moved back together and downwards so that they are placed on the transport device 55 in their narrowest position and are transported on by this.
