一种瓶盖上料拧紧装置

Abstract

本实用新型涉及瓶盖拧紧技术领域，提供了一种瓶盖上料拧紧装置，包括上料组件，以将瓶盖输送到目标位置，还包括：用于抓取瓶盖的抓取机构；旋拧机构，包括旋拧驱动件和旋拧座，所述抓取机构弹性连接于旋拧座的下方，旋拧驱动件用于驱动旋拧座转动；移动机构，用于驱动抓取机构移动，以使抓取机构在目标位置和瓶体固定位置之间移动；以及升降机构，用于驱动旋拧机构、移动机构及抓取机构整体升降，以将抓取的瓶盖压向瓶口。本实用新型抓取机构与旋拧座之间弹性连接，通过旋拧机构转动瓶盖时，瓶盖也会受到向下的弹力，即通过转动瓶盖即可实现瓶盖的拧紧动作，无需使瓶体升降，简化了拧盖动作。

The top of the clamping drive is provided with a guide rod, which slides through the inside of the screw seat and is circumferentially fixed. A limit member is connected to the guide rod above the screw seat, and a spring is sleeved on the guide rod between the screw seat and the clamping drive.

5. The bottle cap feeding and screwing apparatus according to claim 4, wherein The clamping drive is a finger cylinder, and the clamping components are connected one-to-one with the output fingers of the finger cylinder.

6. The bottle cap feeding and screwing apparatus according to claim 1, wherein The gripping mechanism includes a negative pressure component, an adsorption seat, and a vacuum adsorption plate. The vacuum adsorption plate is installed at the bottom of the adsorption seat. The negative pressure component provides negative pressure to the vacuum adsorption plate to adsorb the top surface of the bottle cap. A guide rod is provided at the top of the adsorption seat. The guide rod slides through the inside of the screw seat and is circumferentially fixed. A limit component is connected to the guide rod above the screw seat. A spring is sleeved on the guide rod between the screw seat and the clamping drive component.

7. The bottle cap feeding and screwing apparatus according to claim 1, wherein The lifting mechanism includes a lifting slide, a lifting guide rod, a top plate, a lifting screw, and a lifting drive component. The lifting guide rod is fixedly installed, the top plate is fixedly installed on the top of the lifting guide rod, the lifting drive component is installed on the top plate and drives the lifting screw to rotate, the moving mechanism is installed on the lifting slide, the lifting slide is sleeved on the lifting guide rod and is threadedly engaged with the screw.

8. The bottle cap feeding and screwing apparatus according to claim 7, wherein The feeding assembly includes an upper cover seat, a cap storage component, a pusher plate, and a cap pushing drive component. The upper cover seat is fixedly installed and has a limiting groove on its top. The cap storage component is fixedly installed on the top of the upper cover seat and has open top and bottom to store bottle caps by stacking. The cap pushing drive component is fixedly installed at one end of the limiting groove and drives the pusher plate to move so as to push the bottle caps that fall into the limiting groove to the target position.

9. The bottle cap feeding and screwing apparatus according to claim 8, wherein The lower side of the cap holder is provided with a cap assembly, which includes a stop bar and a cap drive component. The cap drive component is fixed to the side of the cap holder, and the stop bar, under the action of the cap drive component, will tighten or loosen the next cap to be screwed on.

10. The bottle cap feeding and screwing apparatus according to claim 9, wherein The lower side of the cap holder is equipped with a detection sensor to detect whether there is a cap between the next cap to be screwed on and the cap to be screwed on.
