SU1395406A1 - Arrangement for separating upper sheet from a stack and feeding it to the working station - Google Patents

Abstract

The invention relates to the field of cold metal forming and can be used to separate the top sheet from the foot and feed it into the treatment area. The goal is to simplify the design, increase the reliability of work and the performance of the separation and supply process. The sheet separates from the foot and moves to the treatment area by the gripping organs. The gripping organs are mounted on rods hinged to traction organs. The latter have a horizontal section located above the sheet of sheets, and a vertical section located on the side of the sheet of sheets. The traction organs are made in the form of four closed chains arranged in parallel, each of which covers double sprockets. The reciprocating movement of chains with gripping organs is provided from the pneumatic cylinder. 3 il. g

The invention relates to the cold treatment of metals by pressure and can be used to separate the top sheet from the foot and feed it to the treatment area.

The aim of the invention is to simplify the design, increase the reliability of work and the performance of the separation and supply process.

FIG. 1 shows a device for separating a top sheet from a foot and feeding it to a treatment zone; in fig. 2 shows a section A-A in FIG. ; in fig. 3 is a view B in FIG. 2; in fig. 4 shows a section f5 -B in FIG. 3

The device contains grips (vacuum or magnetic) suspended on two rods x 2 and 3, the ends of which are hingedly mounted to the racks 4 fixed on chains x 5, 6 and 7, 8., and the front rod 2 is mounted on internal chains x 6 and 7, and the rear rod 3 - on the outer chains x 5 and 8.

Chains 5, 6 and 7, 8 g are sparsely distributed in the front part of the mechanism on double sprockets 9 and 10. And in the rear part internal chains b and 7 are on asterisks II and 12, external chains 5 and 8 are on asterisks 13 and 14, shifted with respect to asterisks 11 and 12 in .. aol of chains by the value of /. Equal to the distance between rods 2 and 3 in their current position; 1 price to m.

External chains 5 and 8 are provided with deflecting sprockets. L 15 and 16.

The reciprocating movement of chains with gripping bodies 1 is provided from a pneumatic-hydraulic actuator 17 through double sprockets 18 and 19.

The device is equipped with sensors for the extreme positions of the opi aHOB of the same-sized sheets; 1, for ensuring its automatic operation: the sensor of the rearmost position and the sensor of the extreme anterior position (not shown).

Two conveyors are also built into the feed mechanism: one is 20 for stacking the supplied iron stacks, and the second is 21 for receiving and transporting the gripper and iron sheets for the next process operation.

On the conveyor 20, there is a stack of iron and iron 22 of 23. The grips of 1 sn are bristles by stops 24, interoperable: -1-m with the bar 25.

The extreme rear position sensor contains a bracket 26, which is in toothing with I.IJTOKOM 27 of the pneumo-hydraulic drive 17 and freely rotates the shaft with the shaft 28, and the Cropnngain 29, which is fastened to the shaft 28 by means of crankshaft and 30. On the bracket 26, a freely rotating axis 31 is installed, on which: 1 an arm 32 with a pc is fixed. ; IC 33. Axis 31 is made in the form of a rod with a flat .Ц.

On the crown plate 29. The support 34 is rigidly fixed. In addition, the bracket 29 is equipped with an inductive sensor 35, and the bracket 26 is with a) 36. 32 is connected with the bracket

No. 26 with a spring of 37. The stop 38 is rigidly fixed on the mechanism bed. The sprockets 18 and 19 are fixed on the shaft 28. The bracket 29 is fixed on the sleeve 39. The bracket 26 is fixed on gear 30.

The device works as follows.

When the pneumatic-hydraulic actuator 17 is turned on, the movement of the rod 27 through a gear transmission informs the gear 30 with the bracket 26 a rotational movement. The axis 31 of the bracket 26, abutting the cylindrical part against the stop 34, transmits the rotation into a screw; 1ke 39 s crown1, which, using the keys 30, transfers the rotation to the shaft 28. Dual sprockets 18 and 19, on the shaft 28, r, in the movement of price 5, 6 and 7, 8.

The grippers 1 with chains 6, 5 and 7, 8 begin to move to the extreme rear position; reach the stars 11, 12 and 13, 14 they begin to move vertically.

During the reverse of the grippers 1, the stars 18 and 19 do not complete a full turn in the direction of arrow B.

When the feed mechanism approaches the rearmost position, i.e., when the grippers 1 approach the iron sheet stacks 22, the roller 33 runs onto the stationary stop 38 and during further movement: the mechanism 32 is deflected by the lever 32 fixed on the axis 31, which rotates counterclockwise. The cyl m cylindrical part of the axis 31 comes out of contact with the stop 34, since there is an understatement on the axis (Fig. 4).

Further movement of the feed mechanism is prevented by friction between the axle 31 and the anvil 34, i.e., a rigid connection between the leading crown-ng 26 and the follower 29 is eliminated. As a result, the impact of the grips 1 on the stop 22 is prevented.

When the grippers 1 are pressed onto the stack of sheets 22, the rotation of the shaft 28 stops at the same time the axis 31 slips relative to the stop 34. The crowns 26 and 29 are displaced relative to each other, while the flag 36 enters the slot of the inductive sensor 35, which gives n. on rev: 1 stroke of hydraulic drive 17. The movement of the movement to the shaft 28 at the same time through other yi: opbi (not shown).

The spring 37 returns the axis 31 and the roller 33 to the original position. Survival.

The reversing of the pneumatic drive 17 and the grip 1 with the upper sheets taken from the stacks start to lift and then move horizontally to the extreme (e front position where the seized sheets are dumped onto the receiving vehicle) 21. The reset will occur, for example, by pressing the stop 24 n fixed strap 25, located in front of the feed mechanism.

The new feet of the sheets 23 are instead replaced by the use of () to- BaniibiM 22 to the working area of the feed mechanism by means of the conveyor 20, to the free part of which they were previously laid, and so on, the cycle repeats.
