EP3715075B1 - Plate production system with attached distribution device - Google Patents

Description

The present invention relates to a distribution device for a facing material or generally flowable material for use in a slab production plant. Such slab production plants and facing distribution devices are known from the prior art. The term facing refers to the material which is later pressed together with backing concrete to form a slab.

It is known, for example, that several stations are arranged on and/or next to a rotary table, which treat the material to be processed in succession, for example filling the material into a mold, pressing the material and the like. The attachment distribution device serves to distribute the attachment material introduced into a mold, in particular by means of distribution devices within a mold. For example, servo motors with absolute value encoder devices can be used.

In the documents CN 107 650 246 A , EP 1 767 320 A1 and CN 108 214 852 A Distribution devices are already presented which distribute a facing material by inserting pin-like elements into the facing material and moving these elements. Here, CN 107 650 246 A a plate production line according to the preamble of claim 1 and a method for producing plates according to the preamble of claim 11.

In GB 906 542 A A system is shown in which a facing material is distributed by inserting a flat surface into the receiving container with the facing material.

Such forms include slab shapes, such as terrazzo and concrete stone slabs, hermetic-quality paving stones, terrace and pavement slabs or single-layer and double-layer plates, manufactured using combined filter and hermetic press processes.

Such panels are pressed within molds using a hermetic pressing process, with typical pressing pressures ranging between 4 and 24 N/mm ^2. Typical panel product thicknesses range between 8 and 140 mm.

In order to process such facing materials within a press mold, different immersion depths of the facing distributor into the mold are desired due to various circumstances. For this purpose, it is necessary to know that such facing distributor devices are usually introduced into the mold from above by means of a lifting movement.

If the immersion depth is too low, the material may not be distributed sufficiently. If the immersion depth is too great, this may result in material being forced out of the mold.

In the prior art, it is known that such pre-distributor devices are introduced into the mold from above by means of a lifting movement. Such immersion depths could previously only be set up by a system operator using a tool and with great effort during a production shutdown.

The present invention is therefore based on the object of providing a plate production plant with a pre-distribution device which, in the case of such a hermetic press, enables a pre-distribution with different parameters, in particular a different penetration depth of the distribution device.

This object is achieved according to the invention by the subject matter of the independent patent claims. Advantageous embodiments and further developments are the subject matter of the subclaims.

A panel production plant according to the invention with a distribution device for a flowable material and in particular for a facing material, has a receiving container for receiving the flowable material, as well as at least one distribution body which can be at least partially immersed in the flowable material, wherein this distribution body is in a immersion direction. Furthermore, a drive device is provided to effect these movements in the immersion direction, wherein an immersion depth of the distribution body in the flowable medium is adjustable.

According to the invention, the front distributor device is adjustable by means of an adjusting device, wherein this adjusting device has a drive device.

Within the scope of the invention, an automated setting of the penetration depth of an attachment distributor device of the plate production system within a mold is therefore proposed. For example, an attachment distributor device can be provided which has an arm which is arranged above a mold. In addition, however, the mold can also be arranged below the attachment distributor device. The attachment distributor device is preferably arranged above the receiving container, at least in a working mode.

The actuating device particularly preferably has a drive device in the form of an electric drive, in particular a linear motor drive, a pneumatic drive, a hydraulic drive and/or the like. The distribution body is advantageously movable between two end positions. One position can be a position in which the distribution body is at least partially immersed in the flowable material. The second position can be an upper position, in particular a position in which the distribution body is spaced apart from the flowable material.

According to the invention, the receiving container can be moved relative to the front distributor device in a transport direction that deviates from the immersion direction. This transport direction preferably runs perpendicular or essentially perpendicular to the immersion direction. Essentially perpendicular is understood to mean a deviation of less than 10°, preferably less than 5°, from the perpendicular direction. The receiving container can particularly preferably be moved along a circular path. In a preferred embodiment, the receiving container is arranged on a movable and in particular rotatable carrier.

In a preferred embodiment, the adjusting device is an automatic adjusting device. For example, the immersion depth can be controlled via a computer program It is also possible for an operator to enter the corresponding immersion depth. It is also possible for the stroke or the immersion depth to depend on a measured value, for example on the thickness of a plate to be pressed, and/or to be set depending on this plate thickness.

It is possible to use an attachment distributor device that can be moved upwards and downwards. In particular, a lifting cylinder can be provided that is itself movable relative to a stationary sleeve body.

According to the invention, the immersion depth of the front distributor device is adjustable and in particular automatically adjustable. A further drive device, for example a servo motor and/or an absolute encoder device, can be present for adjustment.

In a further advantageous embodiment, the adjusting device adjusts the penetration depth depending on the amount of the flowable material in the receiving container. The device preferably has a control device for controlling the adjusting device. As mentioned, this control device can also check the amount of the material in the receiving container and/or a value characteristic of this amount and/or mass and/or the volume of the facing material can be fed to this control device.

In a further advantageous embodiment, the distribution body is arranged on a carrier plate. Rod-like elements can be provided which arrange the distribution body on the carrier plate.

The distribution body can also have a plate-like or honeycomb-like structure, which causes a distribution of the facing material present in the receiving container.

In a preferred embodiment, the distribution body performs a predetermined stroke in the immersion direction and this stroke is preferably limited on one side by the adjusting device and/or an element of the adjusting device.

It is possible that the position of this adjusting device can be changed in order to change the immersion depth, as mentioned above.

In a further advantageous embodiment, the adjusting device has a stop that is adjustable in the immersion direction and that limits the movement of the distributor device and/or the distributor body in the immersion direction in at least one and preferably in exactly one direction of movement. For example, an element that carries out the lifting movement can be provided that strikes this stop so that the movements in this position are hindered or stopped. This means that the element that moves to the stop is changed in position, so that the stroke is changed as a result. The position of this stop can be changed by the adjusting device. In addition, it is also conceivable that the stop itself is carried along or moved along with the lifting movement.

In a further advantageous embodiment, the distributor device has a guide device for guiding the movement in the immersion direction. For example, at least one or preferably at least two guide rods can be provided, which particularly preferably run in guide sleeves in order to guide the movement.

In a further advantageous embodiment, the adjusting device is arranged above the distributor device. In this way, the lifting movement can be carried out in a particularly convenient manner. The adjusting device is advantageously arranged on a boom and in particular on a pivotable boom. This boom can preferably be pivoted in a plane which also contains the immersion direction. This pivotability allows the distributor device to be pivoted away from the receiving container so that a machine operator can carry out work on the receiving container.

Furthermore, a further drive device, such as a pneumatic or hydraulic drive device, is preferably provided for this pivoting movement of the boom.

In a further preferred embodiment, the receiving container is also movable in the immersion direction. A drive device can be provided for this purpose. In a further preferred embodiment, vibrating devices can also be provided which cause the receiving container to vibrate. In this way, the facing material can be distributed even better within the receiving container. Vibration in different directions is possible, for example in the immersion direction or perpendicular to it.

The present invention is directed to a panel production plant with a front distributor device, wherein a transport device movable relative to this front distributor device is also provided for transporting the flowable material.

This transport device can, for example, be a rotatable carrier on which the receiving container for receiving the flowable material is arranged.

According to the invention, the plate production plant has a measuring device for measuring a quantity of the flowable material present in the receiving container and/or the facing material to be fed to the receiving container.

In a further preferred embodiment, the plate production system has a dosing device which is arranged in front of the front distributor device, in particular in a transport direction of the material or a direction of movement or transport direction of a carrier on which the receiving container is arranged.

In a further preferred embodiment, the plate production system has a control device which serves to control the actuating device, wherein the actuating device is controlled as a function of a value determined by the measuring device. In particular, a control circuit is provided for controlling this actuating device.

In a preferred embodiment, the measuring device is a volume measuring device and/or a weight measuring device. For example, a volumetric measurement or a weight measurement of the material in the receiving container and/or the material to be fed to the receiving container can be carried out.

In a further preferred embodiment, the plate production device has a dosing device for dosing the flowable material into the receiving container, and preferably also a pressing device for pressing the material arranged in the receiving container.

Preferably, this dosing device is arranged in the transport direction of the flowable material upstream of the front distributor device described here and the pressing device is arranged correspondingly downstream of the front distributor device.

This means that the material is first dosed into the mold, then the distribution device distributes the material and finally the pressing device presses the material into the plates.

The present invention is further directed to a method for producing panels, wherein a flowable material and in particular a facing material is introduced into a receiving container and then a distribution body (of the distribution device) is at least partially immersed in the flowable material, wherein the distribution body is moved in an immersion direction to introduce the flowable material and wherein a drive device causes these movements of the immersion direction and wherein an immersion depth of the distribution device in the flowable material is set.

According to the invention, the distribution device is adjusted by means of an adjusting device, wherein this adjusting device has a drive device. An immersion depth of the distribution body in the flowable material is adjusted by the adjusting device.

Advantageously, a vertical lifting movement of the distribution device and/or the distribution body is carried out for immersion. Advantageously, this movement of the distribution device and/or the distribution body is limited in at least one movement device by an adjusting element.

In a further preferred method, the immersion depth is adjusted taking into account an amount of flowable material received in the receiving container.

It is also possible for an immersion depth to be adjusted several times and, for example, to be changed with each stroke of the distribution device.

In a preferred method, a path directed in one direction, for example downwards, is limited by an adjustment element and in particular an adjustment element arranged on the top, which preferably has a stop under its underside. This adjustment element can be automatically adjusted in an automated manner (for example via a control circuit or remotely controlled (for example by an operator) according to a predetermined control and possibly a program.

This results in an automatic adjustment of the immersion depth of the attachment distributor device in a vertical direction, i.e. in a form in which the attachment is already contained, in particular by means of a servo motor and absolute rotary encoder devices.

In a preferred method, the immersion depth is set taking into account the amount of flowable material held in a receiving container. As mentioned above, this amount can be determined, for example, by a volumetric measurement or a weight measurement.

In a preferred method, the immersion depth can be changed for each individual stroke of the distribution device.

The amount of material introduced into the receiving container is determined by means of a measuring device. It is particularly preferred if this amount is determined during or immediately after dosing the material into the receiving container. This can be determined using a flow measuring device or a weight measuring device or a fill level measuring device. However, it would also be conceivable for the amount of material in the receiving container of the distribution device to be determined, for example using a fill level measurement.

These measurements can be automated. It would also be possible to make manual adjustments to these measuring devices or to a fill level, even during ongoing operation. The immersion depth of the distribution device can also be adjusted or changed, even during ongoing operation.

Fig.1 shows a plate production system 50 according to the invention. This has a turntable on which a plurality of processed processing stations are arranged. This reference number 1 refers to a dosing device which doses the material to be fed into a press mold.

The reference number 2 designates a distribution station or the attachment distribution device described in more detail here, which distributes the material filled into a mold, for example a press mold, by the dosing device 1 or effects a uniform distribution of this material.

The reference number 3 refers to a free station. This can be occupied to carry out additional, optional work steps, for example to produce special models of plates.

The reference number 4 designates a back concrete filling station. This can, for example, add another layer of material. In this way, multi-layer panels can be produced. When producing single-layer panels, this station can also be omitted.

The reference number 5 shows a pre-compaction device. This station pre-compacts the material filled into the mold (before the actual pressing process).

The reference number 6 shows the pressing station in which the panels to be produced are pressed.

The reference number 7 designates an output station or removal station in which the manufactured plates are removed or pressed out of their mold.

The reference number 52 designates a rotating transport carrier. By means of this transport carrier, the material is transported from one station to the next station in cyclic operation. The individual stations 1 - 7 are arranged stationary relative to this rotary movement of the transport carrier.

Figure 2 shows a side view of an attachment distributor device. This attachment distributor device has a main carrier 22 on which the actual attachment distributor device is arranged via a boom or arm 11. The reference number 24 designates a drive for pivoting the said arm with respect to a pivot axis S. In this way, for example, repairs can be carried out.

The reference number 14a designates a retractable element of the attachment distributor device or the above-mentioned distributor body. This retractable element can, for example, have a waffle-like structure or generally a structure that is suitable for distributing a flowable material within a receiving container 30.

This retractable element or the distribution body 14a is arranged on an intermediate support or a format plate 14b. For example, four rod-like elements 32 can be provided for fastening. This design has the advantage of a small volume, which could be a hindrance when immersing into the receiving container.

The reference numeral 13 designates a drive or a cylinder which serves for an up and down movement in the direction of the arrow 15b.

The reference number 19 designates an adjustment element for changing and/or limiting the stroke movement of the retracting element. The reference number 16 designates a corresponding drive, for example an electric motor drive, for adjusting a position of the adjustment element 19. In particular, this can be an electric drive, but possibly also a pneumatic or hydraulic drive.

The reference number 13a designates a guide rod. A further guide rod 13b is, however, hidden here by the actual drive.

Figure 3 shows the device from Figure 2 , but here the distribution body is immersed in the receiving container 30. The receiving container is arranged on a carrier. The reference symbol T indicates the immersion depth at which the distribution body is immersed or is immersed in the receiving container 30. This immersion depth is adjustable or can be adjusted as described above. Preferably, an adjustment is also possible during ongoing machine operation.

Figure 4 shows a further front view of the attachment distributor device according to the invention. Here, too, the adjusting element 19 is shown, as well as a lower end 19a thereof.

Figure 5 shows an enlarged view of the Figure 4 shown illustration. Here again the lower end 19a of the adjusting element 19 is shown. This element represents a stop. The front distributor device can be moved downwards until this lower end 19a of the adjusting element 19 hits a stop surface 20 arranged on the top of the cylinder frame of the cylinder 13.

Further downward movement is then no longer possible, since the lower end 19a presses against this upper side of a stop element or an end stop element. In this way, the maximum depth or penetration depth of the distribution body 14a within the mold is ie of the receiving container 30. This penetration depth can be individually reset with each stroke by the adjustment element 19 being reset in a preferably automated manner by means of a predetermined program or control circuit independently of various parameters and thus representing a higher or lower stop relative to the stop element.

When comparing the Figures 6 and 7 It can be seen that when, as in the case with arrow direction 15a, the front distributor device is in an upper position, the guide rods 17a and 17b, which preferably move within guide and fastening sleeves 18a and 18b, have moved upwards.

For this purpose, the cylinder 13, which can be designed as a pneumatic cylinder here, has retracted its cylinder rod 13a for this stroke, whereby the plates 14a and 14b attached to it are moved upwards. This means that the rod elements 17a and 17b in the upper area are moved upwards, as is the adjustment element 19 with its lower stop 19a.

Figure 7 shows a position in which the front distributor device has moved downwards, ie in particular has dipped into the receiving container 30. In other words, the two plates 14a and 14b have moved downwards due to the cylinder rod 13a of the cylinder being extended. The guide rods 17a and 17b have also been moved downwards relative to the fastening element 12.
