Cap taking and feeding mechanism for eye drops filling machine

Abstract

The invention discloses a cap taking and feeding mechanism for an eye drops filling machine. The cap taking and feeding mechanism for the eye drops filling machine comprises a bottle cap gripping device, wherein the bottle cap gripping device is arranged on a piston rod, which extends downwards, of a lifting cylinder; the bottle cap griping device comprises a vacuum sucker with a recessed bottom; the vacuum sucker is connected with a vacuum generator through a tube; the shape of the recessed bottom of the vacuum sucker is matched with that of a bottle cap; the lifting cylinder is arranged on a moving rack through a cylinder seat; the moving rack is arranged on a horizontal sliding track through a sliding seat; a lead screw is parallel to the sliding track; a nut which is combined to the lead screw in a screwed manner is arranged on the moving rack; and a shaft end of the lead screw is connected to an outputting shaft of the servo motor. The bottle cap is gripped in a vacuum absorption manner; the cap taking and feeding mechanism is simple in structure, accurate in action and long in service life, and is accurately positioned by a servo moving mechanism; and requirements of continuous and normal production of the eye drops filling machine can be met.

Description

(1) Technical field: [0001] The invention relates to packaging equipment components, in particular to a cover-feeding mechanism for an eye drop filling machine. (two) background technology: [0002] In the automatic production line of an eye drop filling machine of the applicant company, the cap of the eye drop bottle is screwed on the body of the eye drop bottle using a cap feeding and removing mechanism. In the cap feeding and removing mechanism, a pneumatic three-claw assembly The reciprocating motion from the cap removal position to the cap screwing position is driven by a horizontal push cylinder, and the telescopic movement of the piston rod of the push cylinder drives the pneumatic three-claw assembly to move back and forth, which has the problem of inaccurate positioning, causing the pneumatic three-claw to fail to take the bottle cap. However, running empty or the bottle cap is skewed to cause waste products; in addition, the secondary aspect, the pneumatic three-cl...

[0002] In the automatic production line of an eye drop filling machine of the applicant company, the cap of the eye drop bottle is screwed on the body of the eye drop bottle using a cap feeding and removing mechanism. In the cap feeding and removing mechanism, a pneumatic three-claw assembly The reciprocating motion from the cap removal position to the cap screwing position is driven by a horizontal push cylinder, and the telescopic movement of the piston rod of the push cylinder drives the pneumatic three-claw assembly to move back and forth, which has the problem of inaccurate positioning, causing the pneumatic three-claw to fail to take the bottle cap. However, running empty or the bottle cap is skewed to cause waste products; in addition, the secondary aspect, the pneumatic three-claw will clamp the vase cap, and the main aspect, due to the complex structure and fine coordination of the pneumatic three-claw, it is easy to open and close repeatedly and frequently. Causes damage to the pneumatic three-jaws. During the maintenance or replacement of the pneumatic three-jaws, the automatic production line of the eye drop filling machine will work intermittently, affecting work efficiency.
