Description

O) N9 The invention relates to overhead conveyors. According to the main author. St. No. 1081090, a device for unloading suspensions of a load carrying conveyor is known, which includes a frame mounted on the base through a plate of a moving load carrier and a frame with articulated dumpers connected to each other by a pull connected to the mechanism of rotation of the jumpers jawed on the plate of the swing arm with a roller and a rotatable spring-loaded cam mounted on the base with the rotary lever roller interacting with it, and the plate is mounted on base via parallel rods and hinge. A disadvantage of the known device is unreliability or the impossibility of working during transportation of wired products, since when dropping products from a scoop, the latter is deflected in the direction of dropping. Moreover, the work of a known device becomes unreliable when throwing small (narrow) products with extended suspension with a large number of products on the suspension) or with an asymmetrical filling of the suspension, in this case, it is possible that the dumper pole gets on the suspension rod, resulting in a deviation suspension or deformation of the article without discarding. The aim of the invention is to improve the reliability of the device. cam pivotally mounted on a movable frame with the ability to interact with an additional roller and connected dstvom flexible connection with forcipate levers. 1 shows a device for unloading suspensions of a heavy-duty conveyor, the general view in FIG. 2 is the same, left view; FIG. 3 is a section A-A in FIG. G; figure 4 - section bb in fig. one; on fig.Z - view In figure 4; figure 6 - section GG in figure 1; Fig. 7 is a section of D-D in Fig. 1 (the moment of dropping products from the suspension; Fig. 8 is a view D in Fig. 4; in Fig. 9 a view E in Fig. 3. A device for unloading the suspensions comprises a base 1 mounted on the monorail 2 of the load carrying conveyor. The connecting rods 3, pivotally mounted in the base 1, and the plate 4 pivotally connected to the rods 3, form together with the base 1 a movable parallelogram. forked chippers 7, interconnected tgdy 8. Swivel ha ha connects. 7 with a pivot arm 10 movably mounted on the plate 4 by means of an axis 11 and equipped with a roller 12. The rotary cam 13 and the lever 14 are rigidly fixed on the axis 15 placed in the base 1 (FIG. 4). The spring 16 presses the lever 14 against the stop 17 On the basis of reinforced also limiter 18 With Fig. 2. On the rod of the power cylinder 19, mounted on the plate 4, mounted roller 20. The power cylinder of unilateral action 21 is pivotally fixed on the monorail 2, and its rod is connected to the plate 4. Carriage 22 of load-carrying conveyor equipped with suspension brackets 23, on the bearing hooks the transported products 24 are hung. In the frame 5 spring-loaded springs 25 clamp-shaped levers 26 and an additional cam 27 interconnected by cables 28 through blocks 29. An additional roller 30 is mounted on the lower ejector 7, on which an additional cam 27 is supported. The device works as follows in a way. When entering the unloading zone of the carriage 22 moving along the monorail 2 of the load carrying conveyor, a command device (not shown) switches on the compressed air supply to the piston cavity of the power cylinder 19. The roller 20 moves to the left (Fig. 4) and is set in the path of the carriage 22, then The latter approaches the roller 20 (at this moment, the suspension 23 is combined with the dumpers 7) and moves it to the right (FIG. 6). As a result, the plate 4 of the mobile parallogram, together with the frame 5 and the dumpers 7, performs a plane-parallel motion along the trajectory 1 f ig.c), with the horizontal component of the speed of their movement being equal to the speed of movement of the carriage 22, and the roller 12 of the lever 10 runs onto the cam 13 and rolls along it along the left along the path And (fig. 9). Pivot 10 rotates around axis 11 and, through 9, lifts forks 7, turning them around axes 6. When the eaves 7 is rotated, roller 30 acts on the additional cam 27, pressing it upwards. Connected to the additional cam 27, the cables 28 rotate the levers 26, which, as a result of the rotation, enclose the suspension 23, locking it relative to the frame 5, moving synchronously with the suspension SPHIG (7). Upon further rotation of the ejector 7, the additional cam 27 and the levers 26 stop (the additional roller 30 goes to the section of the additional cam 27, the passage of which corresponds to the movement trajectory of the additional roller 30) The dumpers 7 comb the suspension 23, dropping it from the hooks of the product 24 the top of the lak kuk 13, and the limiter 18 eliminates the further rise of the roller) 2. Since at this moment the plate 4 is moving steeply upwards, the lever 10 rotates in the opposite direction, lowering the release devices 7, i.e. their removal from the suspension 23. Next, the roller 20 goes to the top of the carriage 22 (Fig. 8) and the movement of pastine 4 stops. After the carriage 22 leaves the roller 20 to the right, the commander (not shown) activates the return stroke of the power cylinder 19 and the air supply to the piston cavity of the power cylinder 21. As a result, the roller 20 moves away from the path of the carriages and the plate 4 returns to its original position. In this case, the roller 12 is lowered to the right of the cam 13 along the path W (Fig. 9) and the rotation of the lever 10 does not occur. Approaching the cam 13 from the bottom right, the roller 12 deflects it left to up. As soon as the roller 12 comes out from under the cam 13, the spring 16 rotates into the initial position (with the support of the lever 14 against the support 17). Under the influence of the spring 25, the levers 26 also return to their original position. At this, the operation cycle of the device ends and repeats only after the corresponding command is given. Thus, the proposed device ensures the fixation of the unloaded suspension relative to the movable frame, thereby eliminating the suspension deviation and the release of the resetters on its rods. This makes it possible to drop heavier as well as narrow products that require a small gap in the forked dumpers and increases the reliability of the device.
