Description

2. An apparatus according to claim I, characterized in that the outer plates of the bush-roller chains of the conveyors are made in the form of triangular-shaped necks having holes in the apexes for the hinges of the struts.

3. The device according to PP. 1 and 2, characterized in that the pillars of the hinge four-link units for interacting with the first skein of the group are set at an angle of 85-87 ° to the chains of conveyors.

 The invention relates to devices for packing wire reels, namely, devices for feeding wire reels. The known wire wrapping line includes two packaging machines, a feeder for delivering single coils to packaging machines, two chain conveyor belts With resistant stands, as well as two rotary air lifts that serve to transfer packaged coils to conveyor drives when grouping coils | 1J. . The disadvantage of this line is that the transfer of packaged coils from packaging machines to chain conveyors and formation of cages is carried out by rotary air lifts, with the operations of securing the coil on the pneumatic lifter, turning the latter, orientation of the coils on the conveyors and returning the empty pneumatic lifts to the packing machine zones It is carried out manually, as a rule, by the operator of the packaging machines, which sharply reduces the productivity of the lines. In addition, the presence of removable support posts, which need to be manually mounted on the chain of queue drives after accumulating each load, causes the line to stop; mounting these racks on chains is unreliable, which can lead to a drop in the charge and additional m just. The closest to the one proposed. There is a device for feeding coils of wire containing a feeder, tray, a mechanism for forming groups of windings, chain conveyors with clamps of groups (21; A disadvantage of the known YaVL13 device is that the clamps predetermine the operation of the line when each skein is installed on the receiving conveyor drive and cleaning each group from the conveyor drive, which reduces productivity. The purpose of the invention is to increase the productivity of the work. This goal is achieved by the fact that clamper, tray, mechanisms for forming groups of coils, chain conveyors with clamps of groups, clamps of groups are made in the form of racks hinged on chains of conveyors, while racks fixed on one chain are pairwise connected to one another by means of hingedly fortified crossing legs t g, which form with them hinge four-links, of which the opposing on parallel chains are rigidly connected to each other by means of parallel transverse straps attached to the base of the posts. The outer plastic shells of the roller-roller chains of conveyors are made in the form of triangular-shaped cheeks that have holes in the tops for the hinges of the posts. Racks of hinged four-links for interaction with the first coil of the group are set at an angle of 85-87 ° to the chain of conveyors. FIG. 1 shows the proposed device in the plan; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. ; in fig. 4 - view along the arrow. In FIG. ; in fig. 5 is a cross-section of the FIG. four; in fig. 6 is a software view of arrow D in FIG. . The line contains a feeder, which is a rotary column 1 with two cantilevers 2 and 3 located at an angle of 180 °. Each of the consoles is enclosed by endless roller chains 4c driven to move the coils 5 along the consoles 2 and 3 and to drop them into the tray 6 of the task of the coils (alternately in each of the packaging machines 7 and 8). In the central part of the tray 6 {FIG. 3) there is a rotary platform 9, on both sides of which there are inclined trays 0 having angular levers 11 and pushers 12 serving for pushing out packed hanks 3 from packing machines 7 and 8. Machines 7 and 8 contain driving 14 and supporting 15 rollers and shuttles 6, which carry out the actual packaging of the coils of wire. At the exit of the machines 7 and 8 are installed inclined trays I, for | 1ne and side walls 18 of which are located directly above the sleeve-roller. chains 19 of conveyors 20 and 21. On chains 19, there are articulated clamps 22 attached to them, which serve to keep the cage of packed hanks i3 from sprawling; The rear walls 18 of the chutes 7 have slots 23 for the passage of the clips 22 and the self-folding thrust plates 24, which serve to prevent the skeins 13 from tilting to the left (Fig. 4) during their removal by the chains 19 from the chutes 17 when forming the cage from the dam to the left when the next hank 13 is absent in the tray 17. The plates 24 are hinged on the tracking carriages 25 and, to prevent the plates 24 from turning to the left of the vertical, the carriages 25 are equipped with stops 26 (Fig. 4). Darties 25 are provided with individual pri-, water 27, carrying out their reciprocal movement. The drives 27 of the carriages 25 and the drives of the circuits ix ... ..... ... 19 are controlled automatically by limit switches 28 and 29 and photosensors 30 using copiers 31 mounted on the carriages 25 and ski 32 tracking, which are hinged between chains of 19 bearing branches of conveyor drives. Skis 32 are slightly spring-loaded up and interact simultaneously with the skeins 13 and limit switches 28. Photo sensors 30 are installed on the outer sides of the rear walls 18 of the chutes 17 at the slots 23. Instead of some standard outer plates of the bush-roller chains 19, special D-shaped plates 33 are installed . On these plates there are fasteners 22, made in the form of hinged 4-links, the pillars 34 of which are fixedly connected in pairs by crossbars 35 in the joints. Limit switches 36 are installed in the head part of the conveyors 20 and 21, when interacting with crossbars 35, for disconnecting the drives of these conveyors. For the interaction of the final switch 36 with the crossbars 35 serves ski 37.. . Lini works as follows. in a way. A cargo bracket (not shown) on the console 3 is visited by the coils 5 of the wire, after which the column is rotated 180 °. The console 3 is located above the turntable 9, and the console 2 is located next to the loading bracket for the next load. For feeding the coils 5 to the package, an endless roller chain drive is included. four,. spanning console 3. Chain 4, relocated & the whole package of hanks 5 drops the last hank onto the turntable 9, which is installed with an inclination towards one of the packaging machines 7 or 8. As the hanks 5 are packed, the console 3 is gradually unloaded, alternately dumping the unpacked hanks to the platform 9, which directs them into one or the other side., After the console 3 is completely unloaded, column I reverts to G80, disposal unit. The console 2 loaded with time over the turntable 9. Taking into account the complete symmetry of the withdrawn line, for simplicity, only one side’s work will be considered later (the second side runs in parallel) /; The coil 5 of the wire, dropped on the turntable 9, rolls over it and lies on the long arm of the corner lever P. When turning the lever P, the coil 5, lowering together with the lever P, rolls into the drive 14 and supporting 15 rollers of the packing mask 7, and the corner lever 11 returns to the original position and takes another coil 5, fed by a feeder. Turning on the integrated drive (not shown) of the shuttle 16 and the drive rollers 14, the process of winding the bundle 5 of wire with packaging materials begins (not shown in Fig. 1-5). . ti g% 4m1 With ttf El LI 1 After the packaging is finished by the pusher 12, the packed hank 13 is placed in the tray 17 and, rolling down to the side wall 18, turns onto the chain 19 of the storage conveyor 21 in a vertical position, while supporting it On one side is the rear wall 18 of the tray, and on the other, the slightly tilted front leg of the retainer 22 (at the beginning of the formation of the load), or the previous packaged skein 3. The carriage 25 is at this time in the forward position (Fig. 4) at the retainer 22 or keeps overturning a part of the previously formed motkvs cages. The hank 13 rolled along the chain 19 presses neither the ski 32, which, in turn, presses the limit switch 28. At his command, the drive, 27 of the carriage 25 turns on and it starts moving to the left (Fig. 4), while the stop plate 24 is freely retracted up, and slipping along the surface of the newly arrived skein, passes through the slot 23 of the rear wall 18, while the photo sensor 30 does not work (as the plate 24 passes over the beam of the illuminator. As soon as the copier 31 hits the limit switch 29, the carriage 25 stops and immediately starts moving right, n In this case, plate 24 is already in a vertical position and rests on stop 26. Moving to the right, plate 24 crosses the beam of the photosensor 30, command to move the chains 19, and plate 24 comes into contact with the skein 13. Next, roller chains 19 begin to blow the coil 13, and the carriage 25, moving at the same speed, plate 24 only accompanies the coil (or charge), preventing it from tilting to the left. After the descent of the coil 13 off the ski 32, the latter deflects upwards, lowers the limit switch 28, which interrupts the circuit feeding the drives of the carriage 25 and chains 19. Thus, the coil 13 reaches the previously formed load of the IJ and the yoke of the latch 22. The carriage 25 remains in the right position, supporting the plate 24 with one coil 13 or a group of coils from the opro. being thrown to the left until the next packing hank is rolled onto the chain 19. Thus, each packaged coil of wire, and therefore, a fully formed cage in one cycle, moves a distance equal to the thickness of the next coil 13. After filling the entire coil between the two latches 22 of the chain 19, it moves to a distance equal to the lattice width 22, since in this case the ski 32 will interact with the crossbar 35 of the latch 22. In the event that an extreme preload is not removed from the conveyor-drive in a timely manner, the latter will be stopped, as the crossbar 35 at the next step moving the accumulator will ski 37, which, acting on the limit switch 36, will disconnect the conveyor drive. Equipping the chain conveyors of the coils of wire with locks hinged on the outer plates of the roller chains eliminates the manual operations of shifting the locks on the accumulators, reducing unproductive line downtime, which ultimately leads to an increase in packaging productivity by 8-10%. The proposed economic effect from the use of the invention in the industry, only with the release of part-time packers will be 25-30 thousand.
