Description

one

i The invention relates to the transport of parts and can be used, for example, for supplying: wrenches to a press working area.

The aim of the invention is to improve the performance of the device. FIG. 1 shows the proposed device; in fig. 2 - view A on; FIG. G.

 The device contains stationary step-like directions 2 fixed on the base 1, mounted on racks 3, parallel moving step beams 4 mounted on the base 1 with the possibility of reciprocating movement. Mounted on the carriage 5 moving on the sliders 6 in the guides 7 mounted on the base The carriage 5 has a window 8 allowing the carriage to move relative to the uprights 3. The drive for moving the movable beams 4 has a sprocket 9 mounted on the shaft of the press caster. The sprocket 9 is connected by a chain 10 with a driven sprocket 11, which is mounted on the shaft 12, on which gear 13 and the driving drum 14 are also mounted. The gear 13 is in engagement with the driving gear 16 mounted on the axis 15 and placed on the fixed gear. The fixed guides 2 are placed on a reciprocating movement mounted on the base in the direction of movement of the movable beams 4 of the movable plate 17. The driving gear wheel 16 has an opening in which the crank 18 is connected to a detachable rod 19 connected to movable beams 4. In the drive gear wheel, additional holes 20 are made, located around the axis 15 at different distances from it, the river radially through 60. All holes are cylindrical. For each hole, the radius is increased by a specified amount (depending on the maximum size of the pitch control). ,

The device has mounted on the base of the sleeps 21 and a driven drum 22. The drive drum 14 and the driven drum 22 are interconnected by a conveyor belt 23. On t 19, the hinge is fixed and spring-loaded relative to it to the stop 24 by a spring

25 load dumper 26 (parts 27) with a leash 28.

When using the device, it may be necessary to change the step size (for example, associated with an increase in the dimensions of the workpiece). In order not to violate the consistency between the size of the step on the drive and the size of the steps of the beams 4 and guides 2, regulators 29 are installed on them, with the help of which it is possible to change the size of the length of the steps depending on the step size on the drive. Regulation is accomplished by moving the knobs 29.

The device has at least three parallel movable stepped beams 4. With such a number of beams 4, it is possible to transport asymmetric parts with a displaced center of gravity relative to the longitudinal axis (for example, a wrench for round splined nuts. Three bearing surfaces prevent the parts from tipping over during the movement.

The device works as follows.

From the drive shaft, on which the driving sprocket 9 is installed, the chain 10 transmits the rotation of the driven sprocket 11 mounted on the shaft 12, and from the shaft 12 through the gear 13 to the gear wheel 16. From the wheel 16 through the curve, the hub 18 transmits a detachable movement 19, which drives the carriage 5 with stepped beams 4. Carriage 5 moves in guides 7 at a predetermined pitch. Moving parts 27 speed. With each movement of the moving stepped beams 4 forward, the part 27 is moved one step equal to the pitch. When the beams 4 move backwards, the part 27 is lowered by an amount equal to the height of the step. Moving from step to step, the part enters the stamp area, then part 27 is processed and removed from the stamp area by leads 28 of the ejector. 26. The drop is carried out as follows. First, the carriage 5 is in the rightmost position and the leash 28 of the ejector 26 is on the stamp. The crank 18 rotates clockwise. When the carriage 5 moves forward, the leash 28 of the ejector 26 under the influence of

the spring 25 is pressed against the stamp and sliding along it moves the processed part 27 by the clamp 21. When the carriage 5 moves backwards, the resetter 26 is fixed on the stop 24 and the leash 28. moves along the path of the upper half-ellipse over the part 27 to its original position. From slide 2, part 27 gets to the conveyor belt 23. If necessary, the part can be transferred to another conveyor.

The adjustment of the device to another step is carried out by changing the radius of the crank 18 by swapping it into the corresponding hole 20 of the gear 16, taken out of the press zone, and installing knobs 29 located on the steps of the fixed guides 2 and the movable beams 4. A quick readjustment to another step, as well as the presence of a diverter 26 fixed to the motor 19, greatly improves the performance of the device. The presence of three parallel movable beams 4 allows us to expand the range of processed products.
