Description

Device for feeding crown closures to closure devices

Field of application of the invention

The invention is applied to high performance capping machines and relates to a device for feeding crown closures to capping devices in bottle capping machines from a sorter via stationary feed channels to circlip moving occlusion members, the feed channels having a merge path and sensing members on the delivery channels as well as locks are arranged.

Characteristic of the known solutions

As a result of the constant increase in the capacity of beverage filling lines, the number of bottles to be closed in a certain time unit and thus the number of closures to be supplied to the closure members also increases. Here are difficulties, especially in crown closures with respect to the sorting and di'e supply in the Verschließorganen on.

To overcome these difficulties, a device for feeding Piaschenverschlüssen known (DE 2 119 497), which has a plurality of alignment devices. Each of these

209677

The devices convey the closures into one channel at a time, of which at least two are brought together. In this case, each channel leading to a connection point can be shut off in the direction of closure conveying before or at each connection point by means of a blocking device. In each last channel part, a control sensing element is provided, which is always active only when the channel is before the control sensing element and thereby locks the last feeding channel by its signal and opens another channel. In this case, the last channel part is in each case so large that the closures contained in it are sufficient for closing until the last Vers.chließeinrichtung feeding channel locked and another is open. ,

Furthermore, each channel after the alignment is associated with a switching sensing element, which, when the channel is empty before the Schaltfühlglied, the commissioning of the associated Ausriehteinrichtung triggers and when the channel is full in front of the Schaltfühlglied, the shutdown of the associated alignment effected. These switching sensing elements have electronic delay elements.

The channels are in the known device, as usual, rectangular and have at the merge point a peelable switch · As Sehaltfühlglieder light sources and photocells or mechanical Kihlglieder have been proposed, the latter consisting of levers, which under the influence of a weight in provided recesses of the channels einschwenken and so the Vorenbzw. Determine the presence of closures.

This device has the disadvantage that the mechanical locks by means of tongues and levers are mass-afflicted, d. H. have a certain inertia and so can only be used up to a certain power limit of the capping machine. Furthermore, mechanical barriers are noisy.

Even when transferring from the supply devices to the Verschließorganen itself, interference, in particular by unprocessed closures · This from the slide, for example, when the machine is idling, the Verschließköpfen supplied, in the absence of ingrained vessels, however, not subjected to the Verschließvorgang.en locks block the on the free end of the slideway ready for insertion available closures, so that it. Stowage and bridging during closure transport comes. Of serious nature, however, are disturbances of the closing work by an additionally inserted into the pocket of an already occupied capping closure. Especially in high-performance machines, this circumstance usually leads to vessel rupture and prolonged machine downtime. To overcome this deficiency, it is known (DE 1 939 545) to perform j shutters in a slideway with the assistance of compressed air up to a closure stop and remove it from a driver in the tangential direction. Each locking head is associated with such a driver, which, however, only becomes effective when a likewise associated with each locking head button signals that not already a closure is in the respective pocket of the capping head. In this case, the probe and the driver are arranged with each perpendicular to each other movements in the closing head, wherein a probe and the driver arranged in each case with mutually perpendicular movements in the capping, wherein the probe from a horizontally in the horizontal. movable pin which can be inserted into the pocket and facing a closure stop with the closure diameter matched distance in the same plane · The driver is controlled by the button and engages moved from above radially to the closure. The further transport of the closure takes place up to a fixing in the processing position fixing member z. For example, a mag-
