Ströanordning för framstäl1 Ning av en spänbana

For the production of a chip web for compression into chipboards, spreading devices are used which, by blowing or throwing the chip goods from the warehouse, can land on a forming belt or similar device arranged under them. In such a spreading device, the rollers must be constructed in such a way that they can be monitored, cleaned and replaced. Until now, this has been done in such a way that the private rollers have to be lowered from their operating position all the way to the forming belt under the spreading machine. The high cost of such a way of working is obvious. In addition, the private roller must be disassembled into its parts, such as the roller body and bearings.

The object of the present invention is to improve a spreading device of the above-mentioned nature in such a way that the installation and disassembly times of private rolls are substantially shortened and, moreover, simple handling of the rollers is possible.

Thus, the invention relates to a chip web spreading device for use in connection with chipboards, which has bearing-mounted dosing, feeding and spreading rollers arranged in the housing, preferably with actuators arranged on the same side 2 6801 9 of the housing. Each roll together with its bearings forms a unit to be treated together and the side walls of the housing have at least one opening through which the rollers with their bearings can be mounted and removed. The invention is characterized in that at least one edge of said opening has U-shaped notches formed for mounting and supporting the bearings, the opening being provided with a closure which, when closed, locks the bearings in place in the notches.

A particular advantage of the invention is that the dosing and feeding rollers, when installed, can be monitored very well and, moreover, that their disassembly becomes substantially simpler, since the private roll does not have to be lowered to the forming belt. Thanks to the compact design of the rollers, damage to the roller body or the roller shaft support bearing the bearing cannot occur, since the assembly or disassembly of the unit comprising the roller and bearings can be carried out outside the device without damaging the dust.

According to the invention, at least one edge of the closure of the closable openings delimits a U-shaped notch in the wall of the housing. Thanks to the arrangement of the closure according to the invention, the notches in the wall of the housing, which are intended for the unit formed by the bearing housings plus the roller, can be closed at the same time, so that disassembly can be carried out in the simplest way.

In the accompanying drawings, the invention is illustrated by a schematic representation. In the drawings:

Figure 1 shows a sprinkler according to the invention;

Fig. 2 shows the spreading device partially opened ·,

Figure 3 shows the spreading device seen from the operating side.

As can be seen from Fig. 1, the spreading device 1, which is arranged above the forming belt 2, is arranged in pairs with metering rollers 3, feed rollers 4 and spreading rollers 5. Below the feed rollers 4 there are openings 6 through which both the feed rollers 4 and the metering rollers 3 can be take out. One edge 7 of each closable opening 6 is covered by a closure 8 (see Fig. 2) and thus makes it possible to close the U-shaped notches 9 (see Fig. 2), into the openings 6 of which e.g. complete feed rollers 4 can be inserted.

In order to also be able to take out the dosing rollers 3 through the closable openings 6, there are still other U-shaped openings 10, 3 6801 9 which terminate in the second edge 11 of the closable opening 6.

Figure 2 shows one of the U-shaped openings 9, the others being still closed by the flange bearings 12 of the feed rollers 4 still in place. As can also be seen from Fig. 2, the spreading rollers 5 with their flange bearings 13 are also held by U-shaped slots, so that they can be easily disassembled downwards.

Figure 3 shows the spreading device 1 seen from the operating side. Doors 17 enclose actuators for metering, feeding and spreading rollers. Only the use of motors, e.g. bracket 19 carried by the metering roller 3 a drive motor 18, projects from the use of an enclosed side wall.
