EP2251301A2 - Device for applying caps on containers - Google Patents

Abstract

The device has a machine element drivable around a horizontal axis, on whose periphery multiple pressing elements are provided for receiving a cap (1) on a cap removal and for pressing the cap on a container. The container stands upright on a container carrier and arranged at a sealing position. The container carrier is provided in the form of a transport star for moving the container at the sealing position.

Description

The invention relates to a device according to the preamble of claim 1. The object of the invention is to provide a device which allows a simplified design training closure of containers by simply pressing caps of plastic.

To solve this problem, a device according to the patent claim 1 is formed. Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and from the figures. In this case, all described and / or illustrated features alone or in any combination are fundamentally the subject of the invention, regardless of their summary in the claims or their dependency. Also, the content of the claims is made an integral part of the description.

In the figures, 1 caps, which are made as molded plastic parts and serve to seal containers in the form of bottles 2, by simply pressing and elastic locking the caps 1 at the mouth of the respective container. 2

With 3 is generally designated a device which serves to press the caps 1 on the container 2. The device 3 consists essentially of a about a horizontal axis in the direction of arrow A circumferentially drivable machine element 4, which is designed as a wheel or disc and on the periphery of a plurality of stamp-like Verschließ- or pressing elements 5 is provided, namely parallel to axes controlled to the horizontal axis of rotation of the machine element 4 pivotally by a non-rotating with the machine element 4 control cam. 6

Denoted by 7 is a cap feeder via which the caps 1 are fed close together to a cap removal 8 formed at the end of the cap guide 7, at which the respectively first, ready-made cap 1 is tangential to the rotational movement from the respective pressing element 5 moving past the cap removal 8 of the machine element 4 and withdrawn in the axial direction of the cap guide 7 and then carried on the pressure element 5 with its closed cap top 1.1, for example, held by vacuum, up to a Kappenandrück- or Verschließposition 9, at the respective cap 1 with its open side the mouth of a there below the movement path of the pressing elements 5 waiting container is pressed for closing. The containers 2 are moved past the closing position 9 in synchronism with the movement of the machine element 4, in each case in such a way that when a pressing element 5 is at the closing position 9 there is also a container standing upright, i. is arranged oriented with its container axis in the vertical direction. The closing position 9 is located for example in the region of an imaginary, the axis of rotation of the machine element 4 enclosing vertical plane.

In order to achieve the synchronous movement of the container 2, a conveyor in the form of a transport star 10 driven in rotation around a vertical axis is provided for these containers, which is driven in synchronism with the machine element 4 by means of a transmission.

The device 1 can for example be easily integrated into an existing system in the area of a transport star existing there.

The invention has been described above by means of an embodiment. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention.
