RU1784573C - Device for closing bottles with screw caps - Google Patents

Abstract

Use in closures, for example for closure of threaded neck vials with screw caps. SUMMARY OF THE INVENTION: A cartridge driven by a pneumatic cylinder is lowered onto a bottle with a pre-mounted cap. The head abuts the cover, aligns it, grabs it with threaded bushings and tightens. At the end of tightening, the drag moment increases to a maximum, and fortWtfa starts to scroll in the bearings. The time relay trips and the device rises 2 sludge.

Description

The invention relates to closures for closing threaded bottles with screw caps and can be used in packaging and sealing equipment of the food and pharmaceutical industries

A device for sealing bottles with screw caps, a magnifying body and spring-loaded jaws pivotally mounted thereon is known. However, this device is characterized by the complexity of the design and insufficient reliability

Closest to the proposed technical solution is the twisting head of the capping cartridge to a device for screwing caps on the neck of the vials, including a housing mounted on the shaft and spring-loaded jaws.

The disadvantage of this design is its complexity, insufficient ability to center the caps relative to the neck of the bottle, since the sponges, when entering the cap, are spring-loaded by mini

small size The torque limit clutch has large dimensions. In addition, when the clutch slips, there is a lot of noise.

The purpose of the invention is to increase reliability, productivity and reduce noise during operation of the device, as well as simplifying the design by reducing the dimensions of the device.

This is achieved by the fact that sponges are used in the screw head of the device, each of which is a sleeve freely fixed on the axis, on the outer surface of which a threaded carriage is formed, increasing the entry cone and facilitating the head entry onto the cover due to replacing friction sliding friction The limit clutch is made with a friction unit in the form of textolite discs, which reduces the dimensions of the device and makes it silent.

Figure 1 shows the proposed device; figure 2 is a view of figure 1.

The closure cartridge includes a rod 1, a housing 2, a spring-loaded spring 3, heads 4 with jaws in the form of threaded bushings

5. The threaded bushings rotate freely in the grooves of the head on the axes. The thread pitch corresponds to the corrugations on the cap. The housing 2 is connected to the rod by a pin 6, which protects the housing from falling out and from turning. The limit torque coupling consists of textolite discs 7 and an adjusting nut 8.

The device operates as follows. To screw the lid of the cap previously attached to the neck of the bottle, the cartridge is fed down from the pneumatic cylinder while clamping the bottle against rotation (clamping device and pneumatic cylinder are not shown). The head 4 abuts the lid, aligns it, grips it with threaded bushings and tightens. At the end of tightening, the moment of resistance increases

to the maximum, and the head starts to scroll in bearings 9, the time relay trips, and the device rises. The cycle repeats.
