Description

The invention relates to the use of a device for Loading and unloading a firing table assembly with firing material.

According to the invention, the term “firing table” is first used generally understood a document on which the Firing material placed before, during or after the firing process can be.

It is usually a kiln car, one Plate (a so-called kiln furniture) or around one several "spaced apart roles" formed "area". The kiln is on directly or with the interposition of a plate put on the burning table.

According to the invention, the term “firing stock” includes in particular ceramic parts such as porcelain, sanitary ware etc. The Fired goods can be fired in different types of furnaces. From tunnel ovens and roller ovens are of particular importance as ver continuous ovens and hood ovens or Bogie hearth furnaces as representatives working discontinuously Ovens.  

A firing table for holding items to be burned can vary be constructed.

Various new types have recently appeared in the applicant's house Superstructures for a burning table have been developed.

In one embodiment, the firing table structure looks as follows:
from a support, for example the firing table, at least four supports extend upwards at a distance from one another,
at least two supports are connected to each other by at least one rail,
at least two rails arranged along a common horizontal plane run parallel to one another at a distance from one another and serve to receive the firing material or to receive plates on which the firing material is placed.

A device with a conveyor belt, over the material is stored on a shelf, describes GB 1.109.906. The shelf is placed vertically in the respective loading position procedure.

DE-AS 953 270 describes a device for automatic Charging a trolley revealed. The device includes a kind of support frame with a vertical and horizon Valley movable conveyor belt, which is guided on the support frame becomes. Plates are placed on the conveyor belt and in the Trolley cart placed on bars.

The object underlying the invention is a possibility for loading and unloading a firing table structure, in particular of the aforementioned type, to offer a  automation as far as possible and flexible to the local conditions of the firing table structure is adaptable.

Specifically, the use of a device for loading and Unloading a firing table assembly with the characteristics of Claim 1 proposed.

In this embodiment, the support arms are always from an area outside the firing table structure horizontally below or above the level of the focal to be loaded or unloaded led table structure. To unload the support arms or Then the conveyor belts are raised so far that - depending on Orientation of, for example, rods to accommodate the Kiln furniture and kiln goods - the (at least two) Rods on which the kiln and / or the kiln furniture rest, or directly the kiln furniture lift slightly with the firing material lying on top. After that that or the conveyor belts driven, so the rods (with the firing material or the firing aids) or kiln furniture (with kiln) from the Bring the firing table assembly away. When loading is reversed proceeded. In the latter case, the position is done the rods or kiln furniture then an Absen ken of the support arms or conveyor belts, so that the Rods / kiln furniture on appropriate holders of the Burn table assembly come to the edition.

In these embodiments, even with only one Support arm to be worked, the one or more Conveyor belts (conveyor belts) picks up and guides.

For all embodiments, the support arms next to their vertical adjustability along one horizontal plane can be movable, for example the support arms between or next to a horizontal plane of the To lead the firing table assembly.  

When different support arms move towards and from each other can be moved away from each other easily adapt to local spatial conditions.

The drive of the support frames, support arms and conveyor belts is preferably done by motor. It can be designed that the support arms and conveyor belts individually, in groups or driven together.

In order to safely record or hand over the burning tools (plates) or the fired goods on the transport belts or from the conveyor belts should at least the upper run of the conveyor belts each protrude above the hearing arm.

In the simplest embodiment, a conveyor belt articulated on the associated support arm. It is also possible to support the arm with a recess to accommodate the training associated conveyor belt, then at for example, the upper run of the conveyor belt above the Support arm and the lower run of the conveyor belt below the Support arm runs.

Instead of a single, relatively wide conveyor belt several transport belts can also be spaced apart to be ordered. The leadership and drive of the Trans Port straps are carried out via appropriate drive rollers, tooth wheels or the like.

Another embodiment of the invention provides that the conveyor belts cover only part of the length of the extend associated support arm, so for example with End the distance in front of the free end of the support arm.  

In this way, the front, free end of the support arms Latching means are provided for the non-positive on serve in another support frame, which ent speaking on the opposite of the first support frame Side of the firing table structure is arranged. This further Support frame has the sense and purpose of being absolutely horizontal Alignment of the support arms or conveyor belts ensure, especially when the support arms (Conveyor belts) raised for loading and unloading or be lowered. In this embodiment, the Support arms thus guided at the ends by both support frames, the drive members of the two supporting frames preferred are synchronizable.

The locking of the free ends of the support arms in the further Support frame can be done in any way; it it is only necessary to ensure that the support arms are precise horizontally aligned vertically.

Basically, the device fulfills its purpose with a single support arm and a hinged conveyor belt. It is also possible, for example two, spaced apart mutually arranged support arms with appropriate transport to provide bands that are synchronized in the respective Position can be moved. The two trans port straps to hold one or more plates used one or more parts to be burned will. It is within the scope of the invention, also three, four or more support arms or conveyor belts see a variety of side by side or in a row other arranged burning aids (plates) or burning share record or feed together. Especially with  this embodiment is the synchronization of the individual drive of great importance.

To also the feed to the firing table structure respectively takeover of the firing material from the firing table assembly automate, provides another embodiment, the Carrying a storage for storing the firing material in it assign to several horizontal levels. After another Optimization is suggested to be a height adjustable Guide and removal device for the firing material with the pre connect direction that runs away from the end of the support arms, so that an immediate transfer of material can take place. At In this embodiment, the handover end is always on the support arms connected while the other end area the feed and removal device adjustable in height can be formed. To populate the top level of the The device can then set up the firing table, for example run diagonally upwards, while with a medium one A horizontal feeder or level of the firing table assembly Removal takes place and at the lowest level of the firing table construction the device is inclined downwards. In one In the simplest case there is the feeding and removal device from a conveyor belt or a roller conveyor.

A particular advantage is that the device can be retrofitted to existing systems and only a small one requires mechanical effort.

While previously a burning table or burning table construction manually loaded, especially when it is complicated shaped parts, such as dishes, allows the device according to the invention a fully automatic loading and Unloading a kiln car.  

Further features of the invention emerge from the note paint the subclaims and other registration documents.

Fig. 6 is a perspective view of a support frame according to FIGS. 1 to 3.

In order to clarify the functioning of the device, First, the firing table structure will be described.

With the reference numeral 10 , a firing table is provided overall. A total of ten supports 12 a-k are arranged on the firing table 10 , specifically five supports 12 a-e; 12f-k spaced apart in the longitudinal direction of the firing table 10 .

The supports 12 a-k are inserted in corresponding bores in the firing table 10 .

On each support, a plurality of sleeves 22 are arranged one above the other, between which rails 18 run, which are provided for receiving plates 20 a, 20 d, on which the firing material can be placed. The rails 18 are designed as T-rails, the free T-leg 18 f verti cal and the associated base leg 18 b runs horizontally. The base leg 18 b consists of two sections 18 b ', 18 b'', on each of which a plate 20 a, 20 d can be placed.

The vertically stacked T-rails are separated from each other by sleeves 22, wherein the base leg 18 b rests on a sleeve 22 and arranged the next sleeve on the free vertical T-leg 18 f.

While the car structure with regard to the supports 12 and rails 18 remains unchanged even over several firing cycles, according to the invention, the plates 20 a, 20 d fitted with the firing material are each placed on the rails 18 before the furnace and after the firing process for occupying the firing table 10 removed from the firing table 10 again.

Figs. 1 to 3 and 5 show the associated apparatus.

Referring to FIG. 6, the device comprises a first support frame 50 to which a support arm 52 in a horizontal orientation is articulated. The support arm 52 is vertically adjustable on the vertical legs 50 a, b of the support frame 50 (arrow P1). The support arm 52 consists of a frame 54 . Between the legs 54 a, 54 b of the frame 54 running in the longitudinal direction (arrow P2), at a distance from one another, run two axes 56 a, b, on which rollers 58 are rotatably guided, the drive unit for the rollers 58 not being shown here.

A conveyor belt 60 runs around the rollers 58 and can be driven alternately in the direction of arrow P2.

The upper run 60 a projects above the frame 54 upwards.

From the connecting leg 54 c at the free end of the support arm 52 protrudes a locking lug 62 which fits in a form-fitting manner in a corresponding receptacle 64 of a cross member 66 which is vertically movable on a second support frame 68 .

The support arm 52 is not only adjustable in the direction of arrow P1 (i.e. vertically), but also in the direction of arrow P2 (i.e. horizontally) on the support frame 50 and its maximum extension position in the horizontal direction is reached when the latch 62 rests in the receptacle 64 and the connecting leg 54 c abuts the crossmember 66 .

The vertical drive for the traverse 66 is synchronized with the vertical drive for the support arm 52 on the support frame 50 , so that when the support arm 52 is moved up and down, an exact horizontal alignment of the support arm 52 and thus the conveyor belt 60 is always ensured.

The function of the device according to FIG. 6 is shown in FIGS. 1 to 3, the second support frame 68 being omitted there for reasons of better clarity, especially since it is not a mandatory feature of the device according to the invention.

In Fig. 1, a kiln car 70 with a burning table 10 and a burning table structure according to FIGS . 4, 5 can be seen first. The kiln car 70 can be moved perpendicular to the plane of the drawing. The loading or removal of the fuel plates 20 a, d takes place from the side (here on the right).

For this purpose, the support frame 50 is arranged on the right at a distance from the kiln car 70 . At a distance to the right there is a further support frame 72 , which corresponds in structure to the support frame 50 . From the frame-shaped support frames 50 , 72 , the support arm 52 shown in FIG. 6 in detail is accommodated, which is designed telescopically so that it can be moved not only vertically along the support frames 50 , 72 in the arrow direction P1, but also in the arrow direction P2 (horizontally) and thus under or in the firing table assembly 10 .

The support frame 50 further receives a feed belt 74 which is guided at its opposite end to a support frame 76 arranged to the right of the support frame 72 . The feed belt 74 is arranged to be vertically displaceable along the support frames 50 , 76 in the direction of arrow P1.

In the figure to the right of the support frame 76 there is a shelf-like storage 78 in which the plates 20 a, d with the firing material arranged thereon are (temporarily) stored.

When unloading the firing material from the firing table 10 , the support frame 50 and the arm 52 are first guided into the desired position outside the firing table 10 . Thereafter, the support arm 52 is extended telescopically under or between the plates 20 a, d of the firing table structure until the catch 62 engages in the receptacle 64 of the support frame 68 (not shown in FIGS . 1 to 3).

Thereafter, the support arm 52 and thus the conveyor belt 60 are moved vertically upwards along the support frames until the corresponding plate rests on the conveyor belt 60 and a small piece of the corresponding receiving rails has been lifted off.

In the next step, the support arm 52 moves back and transfers the plate with the firing material via the conveyor belt 60 to the feed belt 74 , which has been correspondingly lowered between the legs 54 a, b of the frame 54 with its corresponding end and becomes the plate with the firing material then brought into the storage 78 via the feed belt 74 and stored there.

The procedure is reversed when loading. The Loading is preferably from the top to the bottom Level performed. Infestation of the goods with foreign particles is prevented at the same time. The device enables but also flexible (variable) loading / unloading individual trim levels, panels or burned parts.

Figs. 2 and 3 show examples of different positions of the support arm 52 (conveyor belt 60) and the feed belt 74 at the loading / unloading of the firing table structure in different positions (heights).
