Description

The invention relates to equipment for the machining of polymeric material and can be used in shoe factories for sorting sheet blanks according to specified dimensions in groups. A device for sorting sheet blanks is known, comprising a table for blanks movable in a vertical plane, a bracket with sheet-mounted stacker, consisting of a plate with vacuum grippers and a pull-pull, drive and flooring for collecting, sorted blanks. The device has a carousel column mounted on a base with the POSSIBILITY of intermittent rotation by means of a Maltinsky mechanism, on which a bracket with sheet-foldrs is attached, each of which has measuring and clamping mechanisms 1. The disadvantage of the kain device is that the vacuum-gripper causes the device to work intermittently that limits its performance. In addition, vacuum grippers complicate the design due to a number of additional mechanisms, which in the tsiannoy case provide an intermittent movement of sheet bricks, as well as provide their movement in a vertical plane to capture the next billet from the common stack to measure them, and so on. The goal of the invention is to increase the productivity and simplify the design of the device. The goal is achieved by the fact that the presser mechanism of each stacker sheet consists of a thrust plate mounted on the lower plane of the stacker plate, two rotatable spring-loaded grippers mounted on opposite sides of the stacker plate, and a vertical spring-loaded pusher connected by flexible cables with rotary grippers, the workpiece table is provided with a horizontal plate with slots for the passage of the clamps, and the carousel column is made with the possibility of continuous rotation from the drive year Figure 1 shows schematically the proposed device, a common vice; in fig. 2 - sheetlayer in the collection; in fig. 3 sheet workers in work; in fig. 4 - measuring mechanism. A device for sorting sheet blanks to a product cutting press consists of a carousel column 1 mounted on a bed 2 with the possibility of uniform rotation, a dispensing arm 3 carrying evenly spaced six similar sheets of sheets 9-9. Each stacker is equipped with a transverse and longitudinal grooves Yu made from its two sides on the middle part. Along the sides of the sheet crushers in the recesses on the rollers 11 and 12, hinged clamps 13 and 14 are installed in pairs to clamp the sheet blanks 15. The rollers 11 and 12 for turning are provided with gears 16 which engage with the toothed racks 17 and 18 interacting with the stop 19 based on. In this case, for fixing the clamps 13 and 14 in the initial and in the working position, the rollers 11 and 12 are provided with a double acting spring 20 and levers 21 for returning. The levers 21 by flexible cables 22 are connected to a squeezing plate 23, which is made with the possibility of vertical movement and is spring-loaded downward on a pusher 24 mounted on a sheet-laying machine. In the middle part of the sheet paver, measuring mechanisms are mounted in the area of the guide grooves 10, which consist of a spring-loaded control rotary plate 25 (with limited rotation), having thrust protrusions 26 at the ends for contact with the sheet stock and an emphasis 27. The control plates 25 in the original position recessed in the recess a, performed on the lower plane of the sheet-laying machine. Thrust plates 28 are also installed on the bottom of the sheet stacker. The control plates 25 are mounted eccentrically on the carriage 29 and are equipped with a spring-loaded retainer 30 fixing its initial position, interact with the release bar 31 and contact through the stop 27 with the limit switch 32. In the carriage 29 the limit switch 33 is installed, to which electr0101 wire is connected. 34. The carriage 29 of the measuring mechanism is made in the form of a sleeve, which is mounted on a horizontal guide rod 35 fixed to the plate of the stacker. A spring 36 is fixed on the carriage 29. The guide rod 35 is hollow with a groove 37 and a screw 38. The screw 28 moves along the groove 37 an emphasis 39, which interacts with a limit switch 33, which is sequentially electrically connected to the switch 32. In addition, on the carriage 29 is mounted reading line 4O. To force the measuring mechanisms to return to their initial position at the top of the sheet-laying machine, a spring-loaded squeeze frame 42 with fixed ends of flexible cables 43 attached to it is connected to the corresponding carriages 29 of the measuring mechanisms on the guide rod 41. The release frame 42 is provided with a lever 44 connected to an electromagnet 45, and a locking lever 46 in contact with an electromagnet 47. On the sheet stacker, one of the measuring mechanisms is equipped with a lever 48 which moves together with the carriage 29 carrying a limit switch 49 to which all limit switches 33 are connected in series. The sheet paver is also equipped with a limit switch 5O, which interacts with the stop 51 on the base, giving the command to release the lever 44. On the base 2 under the bracket 3 there is a distribution disk 52, abraded with six stops 53 moving relative to the reading lines 54 by means of screws 55. To achieve uniform rotation of column 1, the device is equipped with a drive mechanism consisting of an electric motor 56, a belt drive 57 ,, gearbox, made in the form of a worm gear 58, associated with gear 59, which is connected via an intermediate gear 60 with a bevel gear pair 61. Under the spreading machine 5, a table 62 movable in a vertical plane is mounted, which is held on chains 63, enveloping sprockets 64, They are mounted on axles 65 mounted on base 66. A ratchet 67 is mounted on the top axis 65 to move the table up, which is equipped with an adjusting stop 68 that interacts with a tapered protrusion 69 on the bracket 3. On the base 66 on both sides (FIG. 1 and 2), restrictive plates 70 and limiting square 71 are installed, which are intended to be the initial layout of the sheet; workpieces 15. In addition, table 62 is equipped with a shift fork 72, which holds gear 73 on axle 65 in engagement with gear 74 mounted on base 66, which is rotatably drunk only in the direction of table lifting 62, which prevents the table from spontaneously lowering under the weight of the sheet blanks laid on it 15. Table 62 is equipped with a handwheel 75, designed to lift the table in those cases where there are not enough sheet blanks and the table is lowered. Under the sheet-laying machines 4–9, the floorings 76 are installed for dumping sorted sheet blanks 15 on them with a corresponding sheet metal sheet (one flooring is shown), and a restrictive plate 77 for stacking the sheet blank 15 displaced during the movement of the sheet stacker is installed above the floorings. In addition, the device is equipped with a control limit switch 78 installed on the sheet stacker, and a stop 79 fixed on the base 2 and interacting with the switch 78 {stop 79 is shown in understated position). The device is also equipped with a spring-loaded retainer 80, which is mounted on the pressing frame 42 and communicates with the stop 81, and the pad 82, made in the vice plate with grooves b.

A device for sorting sheet blanks works as follows.

At the stop 62, which is lowered to its original position, sheet blanks 15 are placed in a stack, intended for sorting by size. The shift knob 72 is rotated to the working position, i.e., by means of a slit connection of the gears 73 and 74, wherein the squeeze frames 42 are on sheet-and-sheet metal. are in the raised position, all measuring mechanisms on the sheet pavers are also in the initial position for holding d4eT with flexible cables 43, and the release bar 31 holds the control plate 25 in the initial position, while the latter is slightly raised up under the action of a spring in the deepening Q of the layer-laying machine, and its stop 27 touches the switch 32. The ha ha 48 together with the switch 49 is in the initial position. Also in the initial, raised position are the clamps 13 and 14,

they are fixed in this position by the spring 20.

Each sheet-laying machine adjusts to one of the specified sheet dimensions.

blanks, for which the stop wheel 39 is moved in the slot 37 of the carriage 29 to the desired division on the 4O ruler. Accordingly, on the distribution disk 52, by means of screws 55, each stop 53 is moved relative to the rulers S4. From the electric motor, the column 1 rotates uniformly with the bracket 3, as well as with the sheet-laying machines 4 - 9 fixed to it.

over the table 62, the conical protrusion 69 on the bracket 3 reaches the head of the adjusting stop 68 of the stopper 67 and, thanks to the conical shape, turns the ratchet 67 in the direction of

A clockwise movement, from which the axes 65 turn and, by means of the chains 63, raise the table 62 by a predetermined distance. Thus, the top sheet blank 15 is raised

above the limiting plates 7o and

Square 71. Due to the fact that the control plates 25 are recessed into the holes of the sheet paver, the latter does not impede the free movement of the sheet paver. When the thrust plates 28 reach the sheet stock, they pick up the sheet stock from both sides, thus eliminating its displacement, and transport it in the direction of movement of the sheet spreading machine. The sheet blank at the same time enters the platform 82. The protrusion of the rack 17 reaches the stop 19, while interacting with the gear 16. The rollers, along with the clamps 13 turn

Sharpened in working position. Subsequently, under the action of the spring, the clamps 13 pass through the grooves at the platform, 82, and hold the front edge of the sheet blank. Along with this, the

Tel 5O on sheet-sucker 5 reaches abutment 51 on the base, contacts with it, and gives the command to activate an efect-: romagnet 45, which through the lever 44 moves down the squeeze frame 42,

under the action of the spring, the lever 46 fixes this position. At the moment of lowering the squeeze frame 42 on the sheet stacker 5, the flexible cables 43 no longer hold in the initial position two measuring mechanisms which, under the action of the springs 36, move towards the sheet blank together with the control plates 25. At the same time the control plate 25, which is on the front

In this part of the sheet-knife 5 in the recess a slides over the bevel, is pressed and then leaves the recess a. The control plates 25 reach the two measured sides of the sheet blank, while the carriages under the action of the spring 36 still tend to move forward, but with a light touch of the control plates 25 to the sheets; because of the eccentricity, the sheet blank 15 is moved, its wedging on the rod 35. B. Further force of the spring 36 reliably fixes this position, while the bar 31 with a weakened flexible cable of 43 l. is easily pressed.

At the time of stopping the carriage. 29, the switch 33 interacts with the anvil 39, after which the inlet of the switch 49 per ton 48 performs the role of a general switch for the entire stacker 5. At the specified moment, the measured sheet stock, pressed with the front side of the stacker, presses 13, leaves the platform 82 and the opposite end sheet procurement enters the platform 82. At this point, the protrusion of the second toothed rack 18 also reaches the stop 19 on the base, interacts with it, from which the gear 16 rotates and turns with the rollers 12 the clamps 14 into the working floor voltage. Under. the action of the spring 20, the clamps continue to abruptly continue to rotate, pass through the grooves of the b pad of the pad 82, and press the specified end of the sheet blank 15 on the pad 82 itself. The sheet layer 5, moving evenly with the clamped and measured sheet blank, moves to the side of the floor 76, which is installed immediately behind the table 62. The switch 49 touches the stop 53 (if the dimensions of the sheet 15 correspond to the adjustment of this, the stop and the stops 39), turns on the electromagnet 47, which gives the command to rotate the locking lever 46. The lever 46 out Moving from the locking groove of the frame 42, the latter, under the action of a spring, begins to be pressed to the upper position, while the spring-loaded stop 80 picks up the pressing plate 23 from the bottom, lifts it to the upper position. When lifting the squeeze frame 42 under the action of the spring, the cables 43 tighten and squeeze the strips 31, which wedge the measuring mechanisms on the rod 35 and return them to their original position, and the AOR latch fixes the initial position of the control plates 25. With the further movement of the squeezing frame 42, the cables 43, continue for the squeeze bars 31, together with it,

The measuring mechanisms are moved on the sheet stacker 5 to the initial position, overcoming the force of the springs 36. When the squeeze frame 42 begins to reach the upper position, the spring-loaded abutment 80 reaches the abutment 81, is squeezed and moves away from the spring plate 23). So the sheet harvesting after

as the clamps 13 and 14 cease to hold it, it falls on the floor 76. Simultaneously with the reset of the sheet blank on the floor 76, the sheet-laying machine 5 seizes the next sheet-shaped sheet in the specified manner by the sheet-laying machine 4.

Thus, the sheet-laying machines 4 - 9 alternately (they pick up the sheet stock, measure and reset it

on the appropriate flooring 76 according to size.
