Description

The proposed machine is intended for the manufacture of construction mats made of wood, which are wooden sticks, interlaced, depending on the length of the latter, in several places with wire filaments, which serve as the basis. The pharynx is formed by threads protruding through holes in the rods, connected by connecting rods to the crankshaft. The surf of wooden weft boards is accomplished by the pusher. The fabric feed is made by asterisks sitting together with the transfer gears on the shafts, the latter being driven by the gear with incomplete, to stand at the time of the weft, the number of teeth.

FIG. 1 shows a schematic front view of a machine for manufacturing building mats; FIG. 2 is a side view of it; FIG. 3-gear rotation from the crankshaft to the sprockets to feed the fabric into the machine.

The crankshaft 1, which lies on bearings 2 and 3, has a certain number of pairs of knees depending on the interlaced bars (in practice, at least two pairs of knees, the most running number of knees is three pairs), at one of its ends is equipped with a driving pulley 4 receiving rotation through the belt 5 from the corresponding engine (Fig. 1 and 2). Near pulley 4

A bevel gear b is inserted, transmitting the rotation through shaft 7, at both ends of which nonic gears 10 and 13 are fixed to shaft 12 ,. whose rotational speed is twice as large as that of the crankshaft 1, since the binding is obtained in half a turn, the pusher 13 must nail, the boards too, twice. On shaft 12, a crank is fastened, which transforms the rotational movement into reciprocating through an intermediate pull 15. A pusher 13, moving in the guide 16, nails the weft: the bars 47 during their weaving, wedge them into an angle formed by 17-18 wire ( Fig. 1 and 2). To ensure that the tape of the mat, obtained as a result of the smack, does not remain in the set-up, but is removed during its operation and at certain time intervals; stopped, giving the opportunity for interlacing the strips with wire, at the other end of the drive shaft 1 a bevel gear 19 was placed, which gives rotation to the shaft 20 rotating in bearings 21 and 22, on which the bevel gear 23 sits, giving rotation to the wadik 24 (Fig. 3). The gear 25 is fixed on the latter with an incomplete number of teeth in such a way that during one revolution of the roller 24 the gear 25 feeds six diameters 26 and 27 between the bars of the mate. Having an incomplete number of teeth, the gear 25, when rotated, rotates the gears 26 and 27, which have intermeshing between them at certain intervals of time (Fig. 3). The gears 26 and 27 are seated on: shafts 28, and 29, on which the sprockets 30, 31 and 32, 33 are attached, whose pitch must be equal to the supply of fabric on the shaft 34. In order for the gears 1 to not interfere with the interlacing of the slats , as the pusher presses 13, the ratchet 35 is fastened to praise 34, and the corresponding dog 36 is attached.

The weave is as follows. The crank mechanism 1 crankshafts connecting rods 37 and 38, terminated by pins 39 and 40, to which are litanges 41 and 42, which run in guide bearings 43 and 44 and convert the oscillatory movement into reciprocating. In the rods 41 41 42, in the area between the bearing-bearings 43 and 44, there are guide holes 45 and 46 arranged in such a way that if the hole 46 is in the highest position, then the Hole 45 is in the lowest position. Thus, the wire wires passing through the openings 46 to 45 form threads 17-18 to form a pharynx, the meaning of which was mentioned above. Wire strands 17 and 18 for weaving during machine operation, due to the movement of rods 41 and 42, will approach holes 45 and 46 in the rods, at different angles to the axis of the latter, and extreme; holes 45 and 46 will break wire wires . In order to avoid this, in the rods 41 and 42 there are arranged guide holes 45 and 46, which have both the upper and the lower cost, carefully machined. Yet,

no matter how close the guide bars 43 and 44 are, between the MK wire. 17 and 18 there will be some distance, which is undesirable. It is necessary that the wire strands 17 and 18 passing in the rods 41 and 42 lie flat during the interlacing one next to the other. This forces the guide strips 48 and 49 to be placed in front of the woven wooden weft bars 47, the distance between which is equal to two wire diameters and is a certain reserve against sticking or tearing of the wire strands 17 and 18 about the edge 49 and 48. the wire, before reaching the holes in the rods, passes through the fixed guide holes 50 and 51, which are for the same purpose as the guide holes 45 and 46, are carefully machined from the inside (Fig. 1).

The subject matter of the invention.

A machine for the manufacture of construction mats, characterized by the use of rods 41 and 42, receiving movement from the crankshaft 1 by means of connecting rods 37 and 38 and provided with holes 45 and 46, into which the main wires 17 and 18 pass, in order to form a pharynx, which serves to laying in it weft timber bars 47, pushed by the pusher 13, by means of a pull 15 of the crank 14 and gear gears 6, 10 and 11, and for feeding the fabric serve asterisks 30, 31 and 32, 33, sitting together with gear gears 26 and 27 on shafts 28 and 29 receiving rotation from cogs gear 25 with an incomplete number of teeth, in order to form a height, and gear pairs 23 and 19.
