The kind of floor known as a mosaic parquet, which consists of a number of small wooden strips not directly connected to one another, is generally, with a view to being subsequently laid in a building, prepared on the manufacturers premises by the assembly of small wooden strips into a pattern, the strips so assembled being then connected together by means of a sheet of paper or other suitable means. In the past this assembly of the individual wooden strips has been performed almost exclusively by manual labor, the individual wooden strips,
preferably of rectangular shape, being assembled in different directions in order to impart a pleasing appearance to the finished floor. A pattern of chess-board type, in which a specific number of strips with their graindirections parallel are assembled into squares, the squares then being laid side by side with their respective graindirections offset by 90", is very popular.
The object of the present invention is a machine characterized by the fact that the individual wooden strips are conveyed by two feed devices, which are approximately at right angles to each other, to a gate portion whose positively controlled gates open the exit from the feed devices for a certain number of strips at a time in the sequence necessary for the assembly of the desired mosaic pattern.
A typical embodiment of the machine is illustrated in the annexed drawing, in which:
Fig. l is a plan view of the machine,
Fig. 2 is a view in the direction of the arrow a in Fig. 1,
Fig. 3 is a sectional view taken along the line II in Fig. 1,
Fig. 4 is a plan view of an alternative machine in which one conveyor belt is used to carry away the strips fed by two conveyor belts,
Fig. is a view taken in the direction of the arrow b in Fig. 4,
Fig. 6 is a section of the common conveyor belt according to Fig. 4, and
Fig. 7 is a plan view of another alternative machine in which a table is used as the common conveying means for the strips.
Conveyor belts 1 and 2, running over rollers 1a and 2a, lead from machines or strip discharge stations (Figs. 1 and 2) to shaking devices 3 and 4 or other suitable strip feed means in which the strips are aligned by channels 5 formed by ribs 4b and are discharged on to conveyor belts 6 and 7 in a position transverse to the centerlines of said belts. Said shaking devices are disposed between at least one strip discharge station and one conveyor belt each. One of said conveyor belts, 7, leads via rollers 7a to the block assembly device 8, while the conveyor belt 6 abuts the conveyor belt 7 via rollers 6a at an at least approximately right angle between the block assembly device 8 and the shaking device 3. A gate 10 is disposed above the conveyor belt 7, and the conveyor belt 6 is blocked by the gate 11. The flow of strips 12 and 13, which lie on the belt transversely to the centerline thereof and in such a manner as to be ICC freely displaceable thereupon, is arrested or released by the alternate opening and closing of the gates 10 and 11. The gates 10 and 11 can be controlled through control devices in accordance with av specific rhythm so that, as is shown, the alternate squares of strips conveyed from the common region adjacent the discharge portions of the belts 6 and 7 to the assembly device 8 by part 7b of the conveyor belt 7 are disposed transversely and longitudinally of said belt, respectively. In the assembly of the individual blocks or squares into a composite block of sixteen squares, it is necessary that the last square in every group of four squares should be aligned in the same direction as the firstsquare in the group of four squares succeeding it on the conveyor belt. If a block consisting of, for example, sixteen squares of strips is assembled on the assembly device 8, then through a gear not shown in the drawing the group is pushed forward on the assembly device by a pusher 15 and a sheet of paper is glued over it so that the strips are held together. For this purpose a paper spool 16, paper feed rollers 17, gluing rollers 18 and cutting-01f knives 19 are provided alongside the assembly device 8 and are set in operation through a gear not shown in the drawing, by the operation of a pedal 20 by the operator, to coat the underside of a strip of paper with glue and cut it to the desired length. Said strip of paper, coated with glue on its underside, is applied to the blocks by the operator, whereupon the assembled composite mosaic block 22 is discharged under elastic press-up rollers 23 by the pusher 15 on to an automatically lowered stacking table 24.
Fig. 3 shows a cross-sectional view of a strip feeding means in the form of a shaking table. The strips 12 are raised by means of the conveyor belt 2 from a machine or discharge station and fall on to the shaker plate 4a. Said plate is loosely attached to the frame 26 by means of springs 25, so that it can be shaken by a vibrator not shown in the drawing. The shaker plate 4a is provided with ribs 4b forming the channels 5 in which the strips are aligned in a direction transverse to the conveyor belt and are transferred to the conveyor belt 6 via the transfer plate 27 at the lower end of the shaker plate 4a.
Instead of only two conveyor belts, it is also possible to use a larger number of conveyor belts converging upon one such belt.
An alternative embodiment of the machine is shown in Figs. 4 to 7.
The strips are brought up by the conveyor belt 31 and by the conveyor belt 32 approaching said belt at a right angle. Between said two conveyor belts is disposed at common conveyor belt 33 which merely receives squares of strips from the two conveyor belts and conveys them to the collecting table 34, said conveyor belt 33 moving intermittently.
Said conveyor belt 33 is provided at both edges, over a distance equal to the length of one square of strips, with stops 37 to 40 arranged in such a manner that they permit the forward feed of strips from belt 31, at the same time blocking the feed of strips from belt 32, and vice versa. By means of the pushers 35 and 36 squares of strips are fed alternately on to the conveyor belt 33, which moves forward by paces each equal to the length of one square. As each successive group of four squares of strips used for the formation of a block of sixteen squares has a different sequence of longitudinally and transversely aligned squares, the stops must be arranged accordingly, that is to say in such a manner that on the side of the belt that is the left side in the direction of travel the stops 37 and 38 permit the charging of the transversely aligned strips and on the right-hand side of the belt the stops 39 and 40 permit the charging of Patented Apr. 1, 1958 the strips aligned in the direction of conveyance, from belt 32. If the first sequence terminates with a square of transversely aligned strips, then the next sequence likewise begins with a square of transversely aligned strips, the following sequence being thereby yielded: ll- 1 1 1ll -1-1 11- and so forth. Four squares at a time are discharged by a pusher 42 on to the block assembly device or table 34, on which sixteen individual blocks or squares of strips are joined together into a composite block by the gluing on of a sheet of paper or the like.
Belts 31 and 33 are led over the common roller 43, which is given a rotary pacing motion by means not shown;
Fig. 6 shows a longitudinal sectional view of a part of the belt 33 in which the groups of stops 37 and 38 and 39 and 40 respectively are mounted. The movement of the pushers 35 and 36, which must likewise take place in accordance with the aforesaid rhythm, may be elfected by a pressure medium controlled by a control instrument and acting upon a piston, none of these instrumentalities being shown.
A further alternate embodiment is illustrated in Fig. 7. In this embodiment the conveyor belt 33 is replaced by a pusher 4-5 which pushes forward the squares of strips discharged by the pushers 35 and 36 on to the common conveyor table 46. This embodiment necessitates the use of stops 4? which arrest or release the supply from belt 32. Said stops 47, andthe pushers 35, 36 and 45 may likewise be operated by a pressuremedium or electrically through a control instrument.
Various changes and modifications may be made without departing from the spirit and scope of the present invention and it is intended that such obvious changes and modifications be embraced by the annexed claims.
