Description
Technical Field
The invention relates to a discharge base for two belt deflecting rollers of a double belt press, which are arranged one above the other and have a left and a right roller frame, each of which has an upper and a lower bearing surface for a roller bearing having a structural height, wherein at least one roller bearing can be moved in a press-through direction on the bearing surfaces, and at least one roller frame has a substantially horizontal partition, and the upper roller frame part formed by the partition can be connected to the lower roller frame part formed by the partition by means of a connecting element.
Background
The double belt press has two endless press belts, between which the product is compacted using pressure and optionally heat, which act on the belts and thus on the product within at least one belt cycle. The product passes through an extrusion zone in which the strips adjoin one another. The invention is explained below in connection with a double belt press for manufacturing wood fibre boards by compacting wood fibres, fibre tows or fibre chips. Such a double belt press is sold by the applicant under the name ContiRoll. The invention should not be limited to such products. Rather, nonwovens or plastics are also compacted in such presses. The press is therefore usually a double belt press for producing plate-shaped or mat-shaped materials, in particular wood material plates, which is also used, if necessary, for heating material fibers, chips or other loose materials during the production of the plate-shaped or mat-shaped materials, in particular wood material plates.
The two closed-loop belts are each guided by at least two belt deflecting rollers. The upper and lower belt deflecting rollers are mounted on top of each other at the beginning and end of the double belt press. Belt deflecting rollers, which are arranged one above the other at the end of the press nip formed by the two belts, are supported on both sides of the product conveying path in a roller frame, wherein the upper belt deflecting roller guides the upper circulating press belt back upwards and the lower belt deflecting roller guides the lower circulating press belt back downwards. The two rollers thus rotate in opposite directions. The two roll stands are called discharge stands. The roller frame does not necessarily have to be supported on the base of the double belt press, but can also be fixed to its frame.
At least one roll support of the belt deflecting roll is often arranged to be movable in order to be able to counteract lateral belt excursions.
A typical known outfeed roller block is shown in fig. 3 and 4. More precisely, these figures show a side view of one of the two roller stands 5 on one side of the double belt press with the roller bearings 8.1, 8.2 accommodated for the upper and lower belt deflecting rollers 3.1, 3.2. The roller circumference of the belt deflecting roller for pressing the belt is shown in fig. 3 in a dashed and dotted line. Similarly, directly behind it there is a second roll stand, not visible in the figures, which supports two further roll supports of the upper and lower belt turning rolls. The distance between the two roll stands corresponds to the support distance of the belt deflecting rolls.
Here, the roll stand has a single division 10 so that the weight of the stand is not excessive for the lifting device when installed in a factory workshop. The two roll stand parts 6.1, 6.2 are connected (for example by screwing) after the roll has been mounted, for example, to the flange 16 by means of the connecting element 17.
The drive roller of the double belt press is mounted movably in the roller frame of the outfeed block. The bearing window 18, in which the roller bearings 8.1, 8.2 are arranged displaceably on the bearing surfaces 7.1, 7.2, is either in the undercut formation of the roller frame 5 and is closed continuously around (fig. 3) or is closed by a closing element 12, preferably at the end of the double belt press (fig. 4), in order to be able to easily gain access for opening. The bearing surfaces 7.1, 7.2 can be formed by sliding rails, rolling elements or the like.
The lower and upper roll frame parts 6.1, 6.2 of the outfeed base 2 can be either brought to the construction site in the pre-installed state or installed on the construction site itself. According to this prior art, it is difficult to install or introduce the belt deflecting roller or its roller bearing 8.1, 8.2 into the bearing window 18. Or the belt deflecting rollers are held in a crane and the roller bearings have to be threaded into the roller frame parts with continuously closed bearing windows transversely to the direction of belt travel with a second crane (arrangement according to fig. 3). Or the belt deflection roller is guided with its roller support in two pre-installed roller frame parts from behind into the support window and then closed by means of the closing element 12. In this case, the closing element 12 must be screwed after the installation of the lower belt deflection roller in order to serve as a support to prevent the upper roller part from bending when the lower roller or its roller bearing is loaded. The situation is, on the other hand, particularly complicated when the belt deflecting roller has to be replaced at a certain moment.
Such a tapping seat is also shown on the right in fig. 1 of DE19931176B 4. The roller housing is referred to herein as a side plate.
Disclosure of Invention
The aim of the invention is to improve the installation feasibility of the discharge base with its belt deflecting roller.
This object is achieved according to the invention by a double belt press having two endless press belts, in which the product is compacted under operating pressure in a press nip between the press belts, and having a delivery shoe in which two belt deflecting rollers are arranged one above the other, the delivery shoe having a left and a right roller frame, each having an upper and a lower bearing surface for a roller bearing having a structural height, wherein at least one roller bearing can be moved in the press-through direction on the bearing surfaces, and each roller frame has a substantially horizontal partition, and the upper roller frame part formed by the partition can be connected to the lower roller frame part formed by the partition by means of a connecting element, it being provided according to the invention that each roller frame is divided into three parts and has an upper roller frame part, A middle roller frame part and a lower roller frame part, and each roller frame has a partition within the structural height of the roller support for the upper belt deflecting roller and the lower belt deflecting roller.
The term "within the structural height" is to be understood as meaning the span "B" of the height level at which the roll support is arranged. The partition is thus located at a height level within the span. This arrangement results in: at least one roller can be simply placed on the mounted lower roller housing part with the aid of a lifting tool onto the support surface and only then the upper roller housing part can be placed with the aid of a crane. The roller frame parts are connected by means of connecting elements, i.e. screwed to one another, for example on flanges.
However, it is particularly preferred if the roller stand has a partition within the structural height of the roller support for the upper and lower belt deflecting rollers.
This results in a triple division of the roller frame which is particularly easy to handle. The lower roller part can then be fastened, for example, to the base or to the frame structure of the double belt press. The bearing surface for the lower belt deflecting roller is freely accessible in this embodiment from above, so that the arrangement of the lower belt deflecting roller is very simple. The middle roller frame part can then be arranged subsequently and the upper belt deflecting roller and the upper roller frame part can then be arranged subsequently. With this design of the discharge shoe, the end construction of the double belt press is significantly simplified. But there is another advantage that cannot be underestimated. With the triple split, in the case of the current structural dimensions of the double belt press, these three roller frame parts are in the order of magnitude of the dimensions with which they still fit into standard freight containers. Thereby significantly saving freight costs to the installation site.
It is advantageous that: at least the lower belt deflecting roller can be removed from the rack in the pressing direction without releasing the connecting element.
This generally means: openings which are closed by closing elements are provided at the ends of the bearing surfaces of the roll supports for the belt deflecting rolls. After removal of the closing element, the roller bearing and/or the roller shaft can be withdrawn from the outlet socket.
It is preferable that: the roller frame is formed from a 50 to 100mm thick metal plate.
The construction with such thick metal sheets is stable and requires significantly less effort in production than a welded construction.
Preferably: the bearing surfaces are located in the recesses of the roller frame or parts of the roller frame.
This avoids the need to apply the bearing surfaces of the roller bearings for the belt deflecting rollers to the roller stand. That is to say, for example, the thickness of the sheet metal of the frame is used to form the bearing surface.
Provision is advantageously made for: in the roller frame, a bearing window is introduced, in which the roller bearing is movable.
In the case of thick metal plates for use as roller frames or roller frame components, such support windows may be removed by burning.
It is then particularly preferred that: the partition extends through the support window.
The support window is thus opened upwards before the next roll stand component is arranged. This enables easy insertion of the roller support or the entire belt deflecting roller from above. By providing the next roller housing part, the window is also closed upwards and the belt deflecting roller support is in the roller housing window without penetration costs.
Provision is advantageously made for: the frame parts can be arranged one above the other in a form-fitting manner.
Thereby avoiding the following risks: the roller frame part may slip before being connected to the second frame part via the connecting element and in the worst case even damage the belt deflecting roller and its roller bearing. A more stable and more precise tapping seat structure is also obtained as a whole.
Preferably: an adjusting element for orienting the belt deflecting roller is supported on the roller frame.
Thus, a reference surface for adjusting the roll inclination in the direction of belt travel is provided directly on the carriage.
Drawings
The invention is explained in detail below with reference to the drawings. Shown here are:
figure 1 shows a schematic view of a first embodiment of a tapping seat according to the invention,
figure 2 shows a schematic view of a second embodiment of the outfeed seat according to the invention,
FIG. 3 shows a first embodiment of the prior art, and
fig. 4 shows a second embodiment of the prior art.
Detailed Description
Fig. 3 and 4 have already been explained in the description of the prior art.
In contrast, fig. 1 shows a first embodiment according to the invention, and fig. 2 shows a second embodiment. Both figures show side views of the rearmost end of the double belt press 1. The roller frame 5 for the two belt deflecting rollers, namely the upper belt deflecting roller 3.1 and the lower belt deflecting roller 3.2, whose circumference is shown by a dashed line, can be seen. The diverted press belt 4 is shown at the top and also at the bottom. Between the upper and lower press belts 4, a press gap 19 is present, in which a plate-like or mat-like material, not shown, is compacted. The actuators for applying pressure and the heating devices for applying heat required for this purpose are not shown for reasons of clarity.
The outfeed seat 2 is formed by an invisible second roll stand on the other side of the extrusion gap 19. The roll supports 8.1, 8.2 are understandably supported in the roll stand on both sides of the product to be treated.
For this purpose, the roller frame is divided into three parts in these embodiments. The components 6.1, 6.2, 6.3 are formed from thick sheet metal, for example 80mm thick, and have recesses 11.1, 11.2 which form the support windows 18 in the assembled state. The structural height of the roll supports 8.1, 8.2 corresponds approximately to the height of the support window 18.
Here, it is ensured for the gap that the roller support remains movable. For support and better sliding properties between the roll bearings 8.1, 8.2 and the bearing window surface, a sliding lining 9 is used.
The lower roll stand part 6.3 has a bearing surface 7.2 on which the roll supports of the lower belt deflecting roll 3.2 are movable. The middle roller frame part 6.2, which is placed as positively as possible on the lower roller frame part 6.3, also has a bearing surface 7.1 in the recess. The third roller housing part 6.1 covers the other two roller housing parts.
The division between the roller frame parts 6.1, 6.2, 6.3 is at a height level within the structural height B of the roller bearings 8.1, 8.2 including their sliding linings 9. The partition thus extends through the support window 18. It is thus possible to: in the lower roller housing part, the roller bearing pieces 8.1, 8.2 are simply placed from above onto the bearing surfaces 7.1, 7.2 before the roller housing part located above the lower roller housing part is placed and connected to said lower roller housing part by means of the connecting elements 17, for example screw elements and flanges 16.
The two embodiments according to the invention according to fig. 1 and 2 are distinguished only by the following: the adjusting element 13, in this case the hydraulic cylinder-piston system, is supported once on the closing element 12 bearing the window 18 and once on the legs of the recesses 11.1, 11.2. In the embodiment of fig. 1, the lower roll can be removed in the pressing direction F without having to loosen the connecting element. For this purpose, only the lower closing element has to be removed, wherein the load of the upper belt deflecting roller has to be supported if necessary. The embodiment according to fig. 2 has the following advantages: the roller frame parts can be stacked in a simple manner.
With both exemplary embodiments according to the invention, the individual frame parts 6.1, 6.2, 6.3 do not exceed the dimensions of a standard transport container and can be transported in this respect easily to the installation site, taking into account the current structural dimensions of the material holders, by the triple division of the frame 5.
