SU114598A1 - Capping machine for cans - Google Patents

Description

Machines for packing caps of rigid cans are known, consisting of a kinematically interconnected textrop conveyor and roller flare receiving rotational and reciprocating motion. However, in such machines, the internal flaring of the capsule is carried out in a mobile jar, which leads to a complex construction of the machine and complicates its operation.

In addition, in the known machines, there is no device for returning the flapping rollers to their original position, and there is also no device protecting the cone from the cone from overloading. These circumstances also reduce the performance of the machine and its scope.

The described machine is devoid of these disadvantages. In the proposed machine, the flaring is made in the form of a roller holder mounted on the can, pivotally connected to the tail end of the rollers, produced by sh. Flaring. The latter is made by pressing a cone and a bar on the tail of the rollers, causing the rollers to move apart and to press them on the inner side wall of the caps. In this case, the rod with a cone is connected to the eccentric via a lever system, which is equipped with a device that prevents the rod from breaking. The device is made in the form of an adjustable spring, worn on a finger sliding along the eccentric, which transmits a reciprocating movement to the flaring.

A spring was installed between the ends of the tails of the rollers to ensure the rollers returned to their original position, after the expansion process, and to release the rollers from the action of a cone, a louga spring was used, which is located between the shoulder (the bar and the roller holder.

The drawing shows a diagram of the machine.

The machine is made in the form of kinematically interconnected conveyor and roller expansion. Transporter consists of two: x:

textrop belts / and two pulleys 2. The upper branch of the belts passes in the grooves of the base plate 3, through which two locking pins 4, working from eccentrics 5, pass.

Roller flare consists of a roller holder 6, a rotating bar 7 with a cone 8, flare rollers 9, set loosely on the ends of the levers 10. The upper ends of the latter are equipped with rounded bevels. The middle parts of the arms 10 are hingedly connected to the roller holder 6.

The rod 7 is connected by means of levers, 12, and a finger 13 with a rotating cam M.

To protect the bar 7 from breakage when overloaded, a device consisting of a spring 15 is put on the lever 12 and a finger 13 which rests on the upper lip, in which the lever 12 moves freely.

To release the cone 8 from the upper ends of the arms after expansion, a cylindrical spring 16 is applied, located between the collar of the shaft 7 and the roller holder 6. To return the rollers 9 together with the arms 10 to the initial position after the expansion process, the spring / 7

The machine is driven by an electric motor with a gearbox (not shown in the drawing).

When approaching under the flaring, the cans 18, the last stop, are fixed by the locking finger 4. The 19 shtangs 7 with the cone 8 rotate from the gear and the roller holder 6 with the roller 9 under the action of the eccentric 14, on which the finger 13 slides, lower. In doing so, the rollers 9 are inserted into the can cap, and the ring 20 rests on the side of the can. At this moment, the forward movement of the roller holder is stopped, and the rod 7, together with the cone, continues to fall. When lowering the cone 8, it presses on the upper ends of the levers 10 and causes them to move apart, and the rollers 9 press on the inner side wall of the capsule, as a result of which the flaring process takes place.

After the flaring process, the finger 13, interacting with the eccentric 14, is located at the last radius of the latter, the rod 7 with the cone 8 under the action of the spring 21 returns to its original position. The freed upper ends of the levers 10 from the cone 8 under the action of the springs 17 return the rollers 9 to their original position. The process then repeats.

Claims (2)

1. Mask for capping with a cap: there is x cans consisting of a kinematically interconnected textrop conveyor and roller flare receiving rotational and reciprocating motion, characterized in that, in order to simplify the design by carrying out the process of internal flaring capsule in a fixed jar, flaring made in the form of a roller holder mounted on the jar, pivotally connected to the tail part of the rollers that produce flaring when pressed by means of a cone and shtang and, connected through the lever system with the eccentric, onto the tail parts of the rollers, causing the latter to move apart and press on the inner side wall of the caps. 2. The form of the machine according to claim 1, characterized by applying between the ends of the tails of the rollers of the spring, returning them to their original position, after the process of flaring when returning through another spring, located
