Abstract

This invention relates to stepper conveyors. The purpose of the invention is to increase the reliability of the conveyor while increasing its pitch. On the base, there are successively located carrier rods (W) 1 and 2, a drive for lifting and a drive for longitudinal movement, a fixed copier 13 with a groove (P) 12 and a lever fixed on the axis of two shoulders. One shoulder 8 of the latter is located in P 12 of copier 13. Brackets 4 and 15 with vertical P 10 and 16 are mounted on W 1 and 2. In P 10 there is a slider 9, and the drive is made with a carriage mounted with reciprocating motion on the base ( TO). The other arm of the lever is pivotally connected to the slider 9, the axis of the lever is hinged to K, and W 2 is connected to K by means of a leash, one finger of which is fixed to K, and the other is placed in P of the corresponding bracket. At the same time P 12 copier is located at an angle to the direction of transportation. When moving, KW 2 moves to step T. The roller moves along P 12 by the amount of ΔТ and moves the slider 9, and W 1 at the same time moves to the distance T + ΔT. 3 IL.

Description

The invention relates to a machine tool industry, in particular to vehicles of automatic lines of machine tools, and is intended for step-by-step transfer of parts from one line segment to another with a change in tag.

The purpose of the invention is to increase the reliability of the conveyor while increasing its uiaia.

FIG. 1 is a schematic representation of the proposed project; in fig. 2 - the same plan view; in fig. 3 - fragment of an automatic line.

The conveyor contains two support rods 1 and 2 successively located on it, supported on roller 3, bracket 4 rigidly mounted on rod I, mounted ng (the base is longitudinal reciprocating movement 5. On axis 6 of drive 5, there is a double-arm lever with arms 7 and 8. The shoulder 7 of the two shoulders lever is pivotally connected to the slide 9, located in the groove 10 of the bracket 4, mounted on the first pole I. During the transport, the shoulder 8 of the double shoulders has supplied

The roller 11 is installed in the groove 12 of the fixed cam 13 fixedly mounted on the base of the 1D conveyor. The carrier bar 2 is provided with a bracket 15 with a vertical groove 16 in which the end of the driver 17 is located. The actuator 5 comprises a fixed body 18 and a carriage 19. The bar 2 is connected to the carriage 19 by means of a carrier 17, one end of which is fixed to the carriage 19. Groove 12 The copier 13 is angled to the direction of transport.

Next is the lowering of the rods 1 and 2 on the rollers 3 and moving them to its original position.

Invention Formula A step conveyor containing two successively located on the base of the support rods, a drive for lifting the supporting rods and a drive for the longitudinal reciprocating movement of them with a fixed copier with a groove and two shoulders fixed on the axis The rods 1 and 2 have a common actuator 20jj with a lever, one arm of which is separate from the actuator 5. The synchronous lifting of the rods 1 and 2 takes place through a common tram 21. Step change is as follows. For example, take equal length arms 7 and 8 of the lever, i.e. the ratio of their lengths. When moving the carriage 19 of the actuator 5 in the direction of movement of the part 22, the rod 2 moves to step t. At the same time, the roller 11 moves along the groove 12 of the copier 13 by the value of & t and through the arms 7 and 8 of the lever and the axis 6 moves the slider 9 relative to the axis of the drive 5 by the value of & t. In this case, the bar 1 will receive a displacement equal to t, + + iU K. 12 copier 13 is located at an angle to the direction of transport Paz LOM ol neither Y arctg TO t where t is the step size; & t - step change value; K - the ratio of the lengths of the arms of the lever It is placed in a groove of a fixed copier, characterized in that, in order to increase the reliability of the operation of the conveyor with an increase in its pitch, it is equipped with two brackets fixed to the support rods with a vertical groove on each of them and a slide located in the groove of the bracket fixed on one of the rods, the longitudinal movement drive being made with the carriage mounted reciprocally along the base, and the second shoulder of the two arms the lever is pivotally connected to the slide, while the axis of the two shoulders lever is hinged on the carriage, and the other carrying bar is connected to the carriage by means of a leash, one end of which is locked flax on the carriage, and the other is placed in a groove corresponding to the bracket, wherein an immobile copier groove is at an angle to the direction of conveying.  t + ut ,:   "H # FIG.
