Definitions
- a device for applying glue or the like to the edges of plate-like workpieces of material such as veneer or the like comp-rises a glue applying means and a sensing means on each side of the material and operatively connected with the glue applying means in such a way as to apply glue evenly to the edge of the said workpieces, even though irregularities exist along the surface of the workpiece.
- gluing device for applying glue to the edges of veneers gluing nozzles which are rigidly mounted so that they can distribute the glue only along a straight line. This is a disadvantage in cases where glue is to be applied to edges other than straight edges, for example to irregular undulated edges of thin veneers.
- sensing means are provided which are operatively connected with the glue applying means and adapted to sense at least one of the surfaces of the workpiece.
- Such sensing means may be constantly in sensing contact with the surface of the workpiece, thereby to transmit any surface irregularities to the glue applying means so that this is made to follow such surface irregularities and thus the edge to be glued.
- such sensing means are provided in the form of a pair of contact rollers supported by the free ends of rotatably mounted levers, one of which is preferably an angle lever, the two levers being rotatable about a common axis. At least one of the levers may be resiliently mounted so that the respective contact roller will be automatically urged r 0 against the surface of the workpiece.
- Contact rollers arranged in this manner are interdependent in operation and adapted to securely guide a gluing nozzle or the like coupled therewith so as to exactly follow the run of an edge.
- FIG. 3 is a side evelational view of the gluing device
- FIG. 4 is a top plan view of a machine for the tooling of veneer edges, incorporating the gluing device ;of the invention.
- an L-shaped angle 12 (FIGS. 1, 2,. and 3) is fixed which has an outwardly directed horizontal leg 12a and a vertical leg 12]) and which mounts a gluing device 10 including a gluing nozzle 11 for applying glue to the edges of veneers or the like;
- a vertical screw 13 In the outerrregion of the horizontal leg 12a of the angle 12 a vertical screw 13 is arranged, whereas in the'upper region of its vert ical leg 12b an angle lever 15 rotatable about-a pivot 14 is mounted on a pin, bolt or the like.
- the angle lever 15 has a verticalbearing leg 15a which on the level of the pivot 14 is provided with a lever arm 151) preferably extending outwardly (rearwardly) at right angles therefrom and having in its end portion a vertical bore 16 surrounding the screw 13 with large clearance.
- a helical compression spring 17 is arranged on the screw 13.
- the springs 17 are provided to hold the lever arm 15b of the angle lever 15 in a horizontal plane and parallel to the horizontal leg 12a of the angle 12 (mounting plane), that is, in the inoperative position and when a straight workpiece 18a, 18b is passing through the device (cf. FIGS. 2 and 3).
- the two springs 17 are so rated as to obtain an equilibrium of forces.
- leg 15c extends at right angles therefrom toward the side of the veneer and is provived at its free end with a pin or the like mounting a contact roller 19a having a preferably convex contact surface over which the workpieces, such as the veneers 18a, 18b, will pass with their undersurfaces (cf. FIGS. l--3).
- a twoarmed lever 21 rotatable about a pivot 20 and extending in the inoperative position parallel to the leg 1500f the angle lever 15 is mounted on a pin, bolt or the like.
- the lever 21 On its lever arm on the side of the veneer, the lever 21 is provided with a pin or the like mounting a contact roller 19b adapted to be pressed against, and roll on, the upper surface of the veneer.
- the rearward and preferably shorter lever arm of the lever 21 accommodates in its end portion a sliding block 22 receiving with large lateral clearance the shank of an eye bolt 23 provided with a nut 23a.
- the eye bolt 23 is pivotally mounted on a pivot 24 on the lever arm 15b of the angle lever 15.
- a helical compression spring 26 hearing, on the one hand, against the slide block 22 and, on the other hand, against a lug 25 bent at right angles from the lever arm 15b is disposed on the eye bolt 23.
- the rearward lever arm of the lever 21 is urged upwardly by the spring 26, whereby the forward lever arm is pressed with its contact roller 19b onto the upper surface of a passing veneer 18a, 18b (cf. FIGS. 1-3).
- the described gluing device operates as follows:
- the upper contact roller 19b is lifted and the two-armed lever 21 carrying this contact roller 19b urged down onto the veneer by the helical compression spring 26 is rotated about the pivot 20, whereby the eye bolt 28 mounted on the lever 21 and supporting the glue nozzle 11 is pulled up. Since the spacing between the center of the contact roller 1% and the pivot 27 of the eye bolt 28 corresponds to the spacing between the pivot 27 and the pivot 20, the gluing nozzle 11 will be pulled up only by an amount corresponding to half the thickness of the veneer and thus adjusts itself to the middle of the thickness of the veneer.
- the gluing nozzle 11 may be arranged between two parallel twoarmed levers on a rod supported at both ends.
- Such two-armed levers would be mounted on a stationary upright at an infinitely variable distance from each other and connected by a compression spring fixed to their rearward lever arms and urging their forward lever arms provided with contact rollers toward each other.
- the described gluing device for applying glue to edges of veneer or the like by means of a gluing nozzle stands out for simplicity in manufacture, assembly and operation.
- a particular advantage is to be seen in the fact that the gluing nozzle will be always directed to the middle of the thickness of the veneer irrespective of varying thicknesses or undulatory surfaces of the veneer.
- the machine frame 9 of the machine for the tooling of veneer edges supports two pairs of longitudinal beams 30a, 30b and 31a, 31b below which shafts 32 and 33 are supported carrying each a plurality of endless conveyor belts 34 and 35, respectively, arranged side by side and susceptible of being rotated by the shafts 32 and 33 for feeding plate-like workpieces in the direction indicated by an arrow.
- a synchromesh gear 36 is provided for driving the shafts 32 and 33 .
- two lateral milling attachments 37 and 38 are arranged on the machine frame, by means of which the workpieces are machined previous to the gluing operation.
- the other side thereof Whilst one side of the machine frame 9 is stationary, the other side thereof is displaceable by means of two parallel guide rails 39 transversely of the workpiece feed direction, thereby to adapt the machine to the width of the workpiece.
- a pressure cylinder 40, 41 is provided on each side.
- a device for applying material such. as glue or the like to the edges of plate-shaped workpieces of material such as veneer or the like comprising:
- (0) means urging said rollers toward each other to contact both sides of the workpiece.
- one of the said levers is an angle lever and the other lever is pivoted to the free end of said angle lever.
- a device as defined in claim 5 including a threaded bolt provided between the said free end of said one lever and said angle lever to adjust the spacing between said contact rollers.
