Description

The known machine for turning the bags in, including the entrance to the bag, which is not inside the bag of the rolling pin, making a reciprocating movement, and grips for pulling the bags from the rolling pin, does not have a high productivity.

To eliminate this drawback, the described machine is equipped with a carriage, laying, guiding it, strips with hooks and rollers, as well as spring-loaded blades swiveling on fixed axles, and rollers that meet facing one another are used as grippers.

FIG. 1 shows a front view of the machine; in fig. 2 - the same, side view.

On the frame 1 of the machine, the guides, 2 are mounted, along which the upper carriage 5 moves, and the guides 4, along which the lower carriage 5 moves. The carriages 5 and 5 are driven from the electric motor 6 through the gearbox 7, the belt transmission 8 and the crank - crank mechanisms 9 and 10. Above the upper carriage 3 rotary blades mounted on fixed axes are mounted) / under the influence of a helical spring 12. For putting on the bag, the carriage 3 carries spring-loaded guide bars 13 with hooks 14 and rollers 15 that move when carriage movement and 3 on the blade m //. Rolling pins 16 are fastened on the lower carriage 5 for turning the bag and feeding it to the grippers in the form of rollers 17 rotating towards each other. The rollers 17 are rotatably driven by a drive 18 from a pulley 19 of a crank mechanism 9.

The work of the machine is as follows. In the process, both carriages 5 and 5 perform a systematic reciprocating movement up and down along guides 2 and 4 along the frame / machine using crank mechanisms 9 and 10.

The bag is loaded into the car in the lower position of the carriage 3. When the carriage 3 moves down, it is fixed on the guides of the plan No. 125537

13, the rollers 15, moving the blades m //, squeeze them, overcoming the resistance of the spring 12. When the carriage 5 comes to its lowest position, a bag is put on the hooks 14 (not shown). Then the carriage 3 begins to move upwards and there is no bag behind it that is attached to the hooks 14. At the same time, the blades 11 are released from pressing the rollers 15 on them and under the action of the spring 12 they disperse, straighten and pull the bag.

Then, the upper carriage 3 with the stretched bag goes down and the lower carriage 5 rises up. Rolling pins 16 fixed on it abut the bottom of the bag, its bag, turn it over and fed to rollers 17. Rollers 17 pick up the bag, remove it from hooks 14 of upper carriage 5 and from blades 11 and remove it from the car. At the same time, the released hooks 14 put on a new bag. At this time, carriages 3 and 5 begin to diverge. The carriage 3 moves up with the new bag, which is flattened by the blades 11, and the bottom carriage 5 is returned to its original position downwards.

During the next run of carriages 5 and 5, the top carriage 5 lowers and feeds the straightened bag, and the bottom carriage 5 rises, rests against the bottom of the bag, with its rolling pins 16 twists it and feeds it to the exciting rollers 17.

The feeding and turning of the bags in this way takes place continuously, which dramatically increases the productivity of the machine.

Subject invention

A bag reversing machine, including rolling pins entering the bag, reciprocating, and pulling the bags from the rolling pins, characterized in that, in order to increase productivity, it is equipped with a carriage carrying guide bars with hooks and rollers, and spring-loaded blades pivoting on fixed axles, and rollers rotating towards one another are used as grippers.
