Description

At present, the selection of netting sheets is made manually, which hinders the growth of labor productivity in this operation.

The described network sowing machine eliminates this disadvantage by the fact that it mechanizes the fit of mesh screens. At the same time, in order to carry out the attachment of the planting thread to the selection of both a single node such as a dandy and a half-and-half and threading a planting thread of a different quantity with its sagging, the machine is made in the form of kinematically connected mechanisms. These are: the mechanism for spreading the extreme tea netting, equipped with pairwise placed hooks for manually put on them, and the hooks are fixed on spring-loaded rods, equipped with rollers, run in fixed guides and placed movably on two parallelly arranged intermittently moving endless chains x; the mechanism for moving the pick, provided with a discontinuously rotated pair of moving the selection of rollers and a pick-up picker, swinging the drive eccentric; the mechanism for moving the shuttle with the landing thread shap through the mesh cloth through two electromagnets interacting with the tips of the shuttle nz ferromagnetic material and moved vertically by a Krivoshchip-Shatunnymi drives; a mechanism for forming a closed loop of a yarn consisting of a sleeve with grooves covering the shuttle in its position with grooves for passing the yarn that is wound onto the sleeve when it is rotated by means of a gearshift drive; the mechanism of the yarn flint thread, provided with a strap coaxially fastened to the slide, interacting with a drive crank moving along it; a software control device in which

No. 130607-2, four electromagnetic clutches are used, installed one at a time in the distribution mechanisms, moving the pickups, pulling the thread and forming a loop of the thread, and coaxially mounted rotating contact disks that are selectively included in the power supply circuits of the electromagnets and electromagnetic clutches; a device for turning off the drive of the machine when the thread is coming off, made in the form of contacts placed in the shuttle, turning off the relay and clamping the normal end of the thread placed in the slide and when the thread closing the closure contacts of the shuttle.

The mechanism for moving the shuttle 21 with the bobbin of the planting thread 22 through the wires 9 of the net 10 consists of two electromagnets 23 and 24 interacting with the tips 25 of the shuttle made of ferromagnetic material and moved vertically by curvature shaft drives 26, which also receive movement from the camshaft 3 through conical gears 27 and 28. The mechanism for the formation of a closed loop of the thread 22 consists of a sleeve 29 covering the lower position of the sleeve 29 with grooves for the passage of the thread wound on the sleeve 29 when it is rotated. e by means of a gear drive 30 from the camshaft 3 through the electromagnetic coupling 31 and the tongs 32, which hold the landing thread loop 22 on the sleeve. The tongs 32 are driven by an electromagnetic drive, one of the electromagnets 33 of which is fixed on the frame 34 of the machine, and the other electromagnet 35- on the mechanism of 36 ticks 32.

When a pulse of electric current is applied to the electromagnets, the latter are brought together, driven by the tongs 32. The mechanism 37 for the flashing 38 (Fig. 3) of the landing thread 22 is equipped with a bar coaxially fixed with the slide 39, which interacts with the crank 40 moving along it, receiving movement from camshaft; through the electromagnetic clutch 41 clutch.

All mechanisms are controlled using a software device, in which the above-mentioned four electromagnetic clutches 4, 20, 31 and 41 and coaxially mounted rotatables are applied: with contact disks 42, selectively activated in the 23w 24 power supply circuit and electromagnetic clutch 4, 20, 31 and 41 Switching off the drive of the machine when the thread 22 is coming off is made in the form of contacts 43 placed in the shuttle 21, turning off the relay 44 turned on by these contacts, and clip 45 of the initial end of the SNP 22 placed in the shaft and when the thread is coming off 43 shuttle 2},

The operation of the network sowing machine is carried out as follows; som

The mating machine makes the landing of the nettings 10 for the selection 13. On the machine there are two types of planting with four or two (Fig. 3), and the fitting of the landing thread 22 to the selection 13 is carried out as a single node, 46, like a dandy (FIG. 3), as well as with a single half node 47 (FIG. 2).

The mechanism for distributing the extreme ones of the net canvas is jammed. oast the movement and movement of the edge of the mounted web (Fig. 4). Before the gripper, whose 9 rods 7 endless chains 6, abutting rollers 1 against guide rails 12, approach each other, and their hooks 8 come close to each other.

The hooks 8 are manually put on the end cheeks 9 of the net cloth 10, upon further movement of which the rods 7 under the action of springs disperse and stretch the cheeks, thus placing them in the working position for flashing the net leaf 10 with a landing thread 22 and hooking it to the selection 13 - This operation is carried out with the help of a shuttle 21, in which a landing thread 22 is placed on the shank. The thread is exited from the shuttle through a hole in its wall. With the help of a push-pull actuator drive 26 with electromagnets 23 and 24 connected in series, the shuttle 21 makes a reciprocating movement in a vertical plane by flashing through the 9 moving edge of the netting 10. After flashing a certain number of those, the shuttle along with the sleeve 29 is in where it is located, rotates 360 ° (Fig. 5); when this happens, a circulating 22 occurs around the sleeve 29, after which the shuttle 21 begins to move upwards (Fig. 6). At this moment, the "32" pliers close, preventing the landing thread 22 from descending from the sleeve 29.

Having reached the top dead center position, the shuttle then begins to move downward, and the pickup 13, located from the right of the sleeve 29, moves the spreader 18 to the left side, as a result of which the landing thread 22 is circumvented around the rebounds 13.

When the shuttle enters the sleeve 29, the tongs 32 move apart, the landing thread slides freely from the sleeve; in this case, due to the downward movement of the shuttle and its rotation with the sleeve in the opposite direction, the landing thread 22 is tightened. As a result, a half loop is formed on the selection 13. By repeating this operation, a second half loop is formed, forming a single node, 46, of a dandy type (Fig. 3), and by repeating this operation, a one and a half half-headed dangle (Fig. 2) is formed again. The process then repeats, i.e., the hooking of the webbing thread of the netting takes place, and after a certain number of people a NEW node, a dandy, sets up.

Regulation of the flow of the landing thread to the sag of the flap 38 produces a mechanism 37 for delaying the flint of the thread, depending on the type and type of landing chosen. The fire control knob is triggered only during the start of the knotting and after the last knotting by moving the adjustable curl-up spindle 40.

No. 130607 .- 4 Regulation of the supply of electric current pulses to the electromagnetic clutches 4, 20, 31 and 4 T to the electromagnets 33 and 35 of the tongs 32 is carried out using software control (Fig. 8), which provides several options for planting depending on which one and character knots type dandy. By pressing the corresponding buttons 48 on the program panel 49, a program is required. The impulses of electric current, coming from the distributing disks 42, gfivodimy in rotation from the common drive, go through the software console to the corresponding mechanisms.

When the landing thread 22 in the shuttle 21 descends, the drive of the machine is automatically turned off, because at this time the 4-j contacts are activated. When the contacts are closed, the electrical circuit is turned on. The electromagnetic relay 44 which turns off the machine turns on. After replacing the shuttle 21, they tie in a new landing thread to the previous thread thread 22 and again start up the machine with the starting pedal.
