Abstract

The supply container (1) for melting adhesive on a woodworking machine is designed to prevent settlement of heated adhesive on the bottom and sides where it may harden or burn. It has a cylindrical internal wall (2), and is fitted with a rotatable agitator (10). - The agitator can be a double-vaned arm (12) sealed against sidewalls (2) and base (5), and extending at least to filling level. This prevents excessive heating of parts of the adhesive, esp. in automatic gluing mechanisms.

Heatable storage container for hot melt adhesive or the like.

The invention relates to a heatable storage container for hot melt adhesive or the like on wood processing machines. The previously known containers have the disadvantage on that the continuously heated hot melt adhesive, which is at rest, adheres to the walls and the floor, coked or even burned. This can lead to difficulties in further processing, especially in automatic glue application devices. To this one

To eliminate the disadvantage, the container according to the invention has a cylindrical inner wall and is with a rotatable stirring device provided. If this stirrer is rotated at certain intervals, the entire mass in motion and is mixed with each other, so that too great a heating of parts of the same with their disadvantages outlined above can no longer occur. The stirring device is expediently on an im Container mounted on a fixed axis. To prevent the hot melt adhesive from the rotatability of the stirrer impaired, ends the free end of the axis above the level of the container.

According to a further feature of the invention, the stirring device consists of an at least two-winged rotating arm, the Seals tightly on the side walls as well as on the bottom and extends at least up to the filling level of the container. This divides the storage container into two separate rooms, and one can use it on one side Fill in dark glue and light glue on the other. Since there is only one outlet, you can get the one you want Use the swivel arm to bring the glue into the room, which

is provided with the outflow opening. Should then If the other glue is used, the swivel arm is swiveled 180, and after the one is used up it is still in the The other adhesive can then be used as the outlet opening new ones are used.

The drawing shows an embodiment of the invention, namely a heatable storage container in section.

The container 1 has a cylindrical inner wall and is provided at 3 with an outlet opening which opens in channel 4. This leads in a manner not shown to the actual working container. The bottom 5 of the Container 1 is provided with heating elements 6, which the hot melt adhesive to be filled to the required temperature bring. The container 1 is filled up to the mark indicated by 7. In the middle of A shaft 8 is attached to the container 1, the free end of which is above the filling level 7. The stirring device 10 consists of a bearing sleeve 11 with a bearing shaft 14 and the preferably two-wing rotating arm 12. The bearing sleeve is provided with a through-hole or a thread into which a handle 13 can be attached during manual operation,

909813/0590

which is used to rotate the stirring device 10. When the engine is running, the bearing sleeve 11 is directly or indirectly with connected to a preferably electric drive motor. The in particular two-wing rotating arm 12 closes close to the inner wall 2 and the bottom 5 and moreover protrudes beyond the filling level / so that two separate spaces are created, in which, if necessary different or different colored adhesives can be filled, which can then be pressed alternately into the space part having the outlet opening 3. With a three-wing rotating arm 12, three separate rooms are created, etc.

If the outflow opening 3 is attached to the container side wall instead of the bottom part 5, the heating elements can be used 6 or arrange heating channels within a common plane, which simplifies the construction.

A slowly running motor has the advantage that the rotary arm can easily be stopped in a predetermined rotary position, which is particularly important when using different adhesives and only one outlet opening. Precise positioning can also be achieved in a simple manner with an intermittent drive.
