Method and apparatus for serially applying an adhesive onto members of one or more wood stacks
View Patent ↗Serial application of adhesive onto members of one or more wood stacks has controllable supply of pressurized adhesive dispensed onto one face of the member from the adhesive supply, and a mechanism operable to advance stacked supply of members to a platform for adhesive application and a conveyor operable to position a next stack, upon exhaustion of a current stack, in a position from which a member can be adhesively coated. The invention also provides a method in order to operate the apparatus.
1. An apparatus for serially applying an adhesive onto members of a plurality stacks of building elements to provide for subsequent adhesive assisted attachment of the members to a surface, the apparatus comprising:
an elongate element having an upper elongate contact face for members to which a coating, preferably adhesive, is to be applied;
a coating applicator arranged above the contact face;
a storage site for a current stack of articles at one end of the elongate contact face;
one or more bars projecting sideways out from the elongate element;
a pusher means for pushing a lowermost member in the current stack onto and along the elongate contact face, under and past the coating applicator; and
conveyor means for storing a plurality of stacks and operable to place a next stack, upon exhaustion of the current stack, in a position at one end of the elongate contact face from which the lowermost member of the next stack can be pushed onto and along the elongate contact face, under and past the coating applicator for applying the adhesive onto members of the plurality of stacks of building elements.
2. The apparatus according to claim 1 , wherein the bar or bars are pivotally connected to the elongate element about a vertical axis.
3. The apparatus according to claim 1 , wherein the bar or bars and the elongate element are provided with supporting wheels that allow translational movement along an underlying surface such as a floor.
4. The apparatus according to claim 1 , wherein the storage site includes at least one vertical bar which projects upwards from one side of the elongate element.
5. The apparatus according to claim 4 , wherein the vertical bar or bars are pivotally mounted on the elongate element about a horizontal axis.
6. The apparatus according to claim 1 , wherein the coating applicator is mounted on the elongate element by means of a vertical bar which preferably is pivotally mounted on the elongate element about a horizontal axis.
7. The apparatus according to claim 6 , wherein the coating applicator is connected to a coating container which is supported by a bar projecting horizontally from the elongate element, the bar preferably being pivotally mounted on the elongate element about a vertical axis.
8. The apparatus according to claim 1 , wherein the pusher means receives motive force from an electric motor.
9. The apparatus according to claim 1 , wherein the pusher means receives motive force from a compressor.
10. The apparatus according to claim 1 , wherein the conveyor means is pivotally mounted to the apparatus.
11. The apparatus according to claim 1 , wherein the conveyor means operation is selectable as automatic or manually controlled.
