Problems solved by technology

However, this solution is still dangerous, because in the confluence area the covers collide and thus block each other, resulting in a blockage of the covers
It must be noted that, in addition to the necessary downtime to straighten the cover, the collision of the cover often results in poor surface condition of the cover

Embodiment Construction

[0018] see figure 1 , shows a cap supply unit 1 as part of a container processing machine in which molded containers are cleaned, filled and then capped. The caps 2 are placed in bulk into at least one hopper (not shown), for example of the rotating / vibrating plate type, located on the upper part of the machine frame.

[0019] Caps 2 are fed from the hopper into at least two cap supply lines, eg a first cap supply line 3 receiving a first row 5 of caps 2 and at least one second cap supply line 4 receiving a second row 6 of caps 2 . All covers 2 in the same row have the same concave orientation, preferably facing upward relative to the frame.

[0020] The cap supply lines 3, 4 can be connected to a common hopper or to different hoppers. The cap supply lines 3, 4 preferably consist of stainless steel wire guides.

[0021] The cap feed lines 3, 4 have a horizontal section which can move longitudinally or laterally along all or part of the frame, depending on the speed and / or p...

Abstract

A cap feeding unit (1 ) comprising : a first cap feeding line (3) receiving a first row of caps (2), at least one second cap feeding line (4) receiving a second row of caps (2), said first and second cap feeding lines (3, 4) merging into one single cap feeding line (10) at a junction area (9), a rotary drive unit (11 ) positioned in the vicinity of the junction area (9) and including: a first starwheel (13) comprising a plurality of radial arms (15) engaging the first row of caps (2), at least one second starwheel (14) comprising a plurality of radial arms (16) engaging the second row of caps (2) and positioned with an angular shift with respect of the first starwheel (13).

Description

technical field [0001] This invention relates to the container industry, and more particularly to closures for containers. [0002] Once the containers are filled, they are immediately capped on a capping unit, the caps being supplied by a cap supply unit at a rate equal to the capping rate (ie filling rate). At present, this rate can reach tens of thousands of pieces per hour. Therefore, it is very critical that the cap supply unit works at maximum speed with minimum downtime. Background technique [0003] In a conventional cap supply unit, caps enter a cap supply line from a hopper, and a single row of caps moves towards the capping unit by gravity. A disadvantage of this technique is that, due to the high speed of the caps, the caps run the risk of jamming along the supply line. Some manufacturers solve this problem by providing error proofing solutions, eg European patent EP0782888 (Lenzi). However, this sub-solution increases the complexity of cap handling, since th...
