Description

one

The invention relates to mechanical engineering and can be used in machine tool construction for stirring, blanks for workplaces, in the food industry for moving cans to can packing machines, etc.

a step conveyor is known which contains an endless belt with deflecting drums and supporting rollers, in which the belt is moved to step 1.

The disadvantage of this conveyor is the complexity of its design.

The closest known solution is a stepping conveyor that includes a belt, envelopes, a mechanism for moving the belt and a drive 2.

The disadvantage of this conveyor is that, in order to achieve a shaggy movement of the belt, it is clamped between the grooved cross member and the guide, which are included in the stepwise movement mechanism of the belt. The constant interaction of the stepping mechanism with the belt leads to an increased belt wear, as a result of which the reliability of the operation of the conveyor is reduced.

The aim of the invention is to increase the reliability of the conveyor.

This goal is achieved by the fact that the stepping mechanism is made of a rod mounted with the possibility of a reciprocal movement, on which two sprockets are installed, the drive also has a drive sprocket, and the drum shaft is equipped with a driven sprocket, and the sprockets on the rod lead and the stars are connected by a chain.

10 FIG. 1 shows a general view of the step conveyor; in fig. 2 is a view along arrow A in FIG. one.

The conveyor includes a drum 1 envelope, a drive- that contains a drive sprocket 2 mounted on a shaft

15 of the drum driven sprocket 3, which by means of chain 4 is connected with the driving sprocket 2, a tape moving mechanism comprising sprockets 5 and 6 fixed on the shack 7, made with the possibility of reciprocating movement in supports 8, sprockets 5 and 6 are connected with leading 2 and driven 3 asterisks by means of chain 4 through guide sprockets 9, leading 10 and driven 11 gears, additionally known asterisk 12 mounted on the swivel bracket 13 of the housing 14. On the rod 7 there are mounted stops 15 and 16 Additional leading star Cup 17 is installed on the shaft of the drive sprocket 2 and through the chain 18 is connected to an additional driven sprocket 12. The conveyor operates as follows. Drive sprocket 2 via chain 4 transmits rotation of driven sprocket 3 and belt 1. Chain 4 is engaged with guide sprockets 9 and sprockets 5 and 6 with sprocket 7. Rod 7 performs reciprocating movement with an additional drive sprocket 17 additional driven sprocket 12, chain 18, and a pair of gears 10 and 11, which alternately engage with the rod 7, thanks to the swivel bracket 13 and the stops 15 and 16. When the driving sprocket 2 rotates, the asterisk 17 transmits the rotational movement of the asterisk ke 12 and gear 10 that is engaged with the rack 10. The rod 7 with the stars 5 and 6 moves downwards. The speed of rotation of the sprocket 3 and, consequently, the speed of the belt 1 will be greater than the speed of rotation of the leading sprocket 2 by an amount equal to half the speed of the translational movement of the rod 7. When it comes to its lowest position, the rod 7 with its support 15 turns the brace 13 around the axis, gear 10 disengages from the rail and gear 11 engages with the rail of rod 7. Rotating in the direction opposite to the rotation of the pinion 10, gear 11 moves the rod 7 with the sprockets 5 and 6 fixed on it upwards. Moreover, if the speed of movement of the rod 7 is 2 times less than the peripheral speed of the driving sprocket 2, then the speed of the driven sprocket 3 and the belt will be equal to O, i.e. the conveyor 1 will stand. Bringing to the extreme position, the rod 7, by means of the stop 16, rotates the bracket 13 and engages the gear 10 with the rack and the cycle repeats. The described cycle of the conveyor is one of the possible. The number of teeth on the sprockets 17 and 12, i.e. the speed of bar 7, is changed; instead of a stepping conveyor, you can get a conveyor with a variable speed of movement. If the speed of the boom 7 is greater than the speed of the leading sprocket 2, then when the boom 7 moves upwards, the conveyor will move in the opposite direction, i.e. the conveyor cycle will be: a long way forward and a short backward course. Thus, the step conveyor has wide operational capabilities: a simple conveyor, a step conveyor, a variable speed conveyor and a conveyor having a return stroke in the cycle. The conveyor can be used to feed the cans in a packaging machine when, during a stop, the cans are removed from the conveyor by the working tool of the packaging mashine. The movable rod 7 can be driven by hydraulic pneumatic or other means. In this case, it is possible to control the speed of movement of the movable bar 7, which will further extend the operational capabilities of the conveyor. The invention includes a stepper conveyor, including a belt, an envelope of drums, a mechanism for moving the tape and an actuator, characterized in that, in order to increase the reliability of the conveyor, the drive mechanism is made of a reciprocating movement on the shaft, on which two sprockets are mounted, and the drive has a drive sprocket, and the drum shaft is provided with a driven sprocket, while the sprockets on the rod, the drive spindle and the drive sprocket are connected by a chain.
