Description

The invention relates to a push chain link of a conveyor chain of a conveyor system for the transport of objects hanging on holding adapters, which has a base body, and at least one protruding driver is arranged on an underside of the base body of the push chain link. The invention also relates to a conveyor chain with such a push chain link.

From the European patent application EP 2 818 434 A1 a conveyor chain of a conveyor system is known, which serves for the transport of objects hanging on holding adapters and which consists of several chain links. Each chain link has a base body with lateral Reibungsrollenandruckflächen on which friction rollers can be pressed to drive the conveyor chain in a first, upper track of a rail profile in the conveying direction. Furthermore, the chain links are designed as connecting chain links or as push chain links. The link chain links are flat on their underside, or have short lands sized to not abut with retaining adapters traversed beneath the first track on a second track. The push chain links have on their underside two protruding drivers. A first, front driver is shorter than a second, rear driver. Both drivers are dimensioned in their longitudinal extent down, in the direction of the second career so that they abut a guided in this career holding adapter, detect this and move in the conveying direction.

The drivers can wear out and break. To change then the entire conveyor line must be stopped and the affected part of the plant to be stopped. This leads to downtime of the system and is associated with great time and cost.

The invention is therefore based on the object to provide a push chain link with at least one driver, in which a repair and replacement of the driver is simplified. Also, a conveyor chain with such a simplified interchangeable push chain link is proposed.

This object is achieved by a push chain link with the features of claim 1 and a conveyor chain with the features of claim 15. In the dependent claims 2 to 14 advantageous embodiments of the invention are given.

Advantageously, in a push chain link of a conveyor chain of a conveyor for transporting objects hanging on holding adapters, which has a base body, and at least one protruding driver is arranged on a lower side of the base body of the push chain link, a simplified repair and an improved replacement is achieved in that the at least a driver with the base body of the push chain link via a detachable connection can be fastened.

In other words, the at least one driver, which may be designed in several parts and in particular in two parts, is fastened via a detachable connection with or on the push chain link, so that the driver is easily replaceable if necessary.

The detachable connection between the base body and driver has the further advantage that driver and base body need not be made of the same material. In particular, a wide variety of materials can be used to make the driver in terms of, for example, elasticity, hardness, etc., e.g. to increase the breaking strength or to be resilient at higher resistance and not to break. Also allow the different materials to adapt to the required flexibility in each application, z. B. for the Drüberrutschen etc. In addition, the facilitated changeability of the driver allows a variable configuration of the shape of the driver. Depending on the application differently configured drivers can be arranged in a conveyor chain and replaced quickly and inexpensively with changing application. So it can be used a basic conveyor chain from always the same base bodies, which are equipped only with specific drivers depending on the purpose.

For the exchangeability of the driver, it is preferably provided that the detachable connection between the at least one driver and the base body is designed positively and / or non-positively and / or cohesively.

In this case, in particular for the positive connection, for example, a tongue and groove connection, dovetail connection, feather key connection, etc. in question.

It is also conceivable that the releasable connection positively and non-positively, such. is a screw or a bolt connection. Thus, the driver could be screwed into the base body, fitted or pressed.

Preferably, the releasable, material-locking connection is an adhesive connection. Particularly preferably, this releasable adhesive bond is curable by means of ultraviolet light and also soluble by means of ultraviolet light again.

In a preferred embodiment of the invention, it is provided that the detachable connection additionally comprises a fixing means, wherein the releasable connection between the base body and driver can be fixed by the fixing means. This fixing means may in particular be a bolt, a screw or releasable snap connection. In other words, drivers and base bodies can be fastened together for releasable connection with a fixing agent. This is preferably possible in addition to a form, force or material connection and serves to counteract the falling out of the driver in a direction in which the positive and / or non-positive connection does not work.

In a particularly preferred embodiment of the invention, the driver consists of a base member and a neck member, wherein the base member is fixedly or detachably attached to the base body of the push chain member and extends the neck member, starting from the base member of the base body of the push chain link away.

It is advantageous to attach the base element via a detachable connection to the base body. Alternatively, it is advantageously possible that the base element can be fastened via a detachable connection with the neck element. Particularly advantageous is the basic element both via a releasable connection with the base body of the push chain link, as well as a further releasable connection with the neck element, fastened. In the latter case, therefore, a tripartite is given.

In a further preferred embodiment of the invention, the releasable connection has a latching nose for releasably locking the driver in the form and / or adhesion. This locking lug is to prevent the driver can slip out of the detachable connection in particular transversely to the conveying direction.

In an advantageous manner may alternatively be provided that the base body has at least one recess for receiving the driver. The recording is preferably positive and / or non-positive and / or material fit. In particular, the recess is a downward, ie in the direction of the driver, open threaded bore and the driver at its, the base body end facing equipped with a corresponding thread.

According to a particularly preferred embodiment of the push chain link two protruding and detachably connectable to the base body driver are arranged on the underside of the base body of the push chain link. Due to the arrangement of two carriers on the push chain link, a holding adapter can be received without play or at least largely free of play between the first driver and the second driver.

It is advantageous that for backlash-free or at least largely free of play recording of the holding adapter in the conveying direction front, first driver is shorter than a rear, second driver, wherein the positioning between the two drivers can be advantageously carried out in a coupling region.

A particular advantage of the invention is that it is possible by the detachable attachment of the driver on the base body of the push chain link, that the driver and the base body of different plastic materials can be made in one or two pieces, in particular by injection molding. In particular, it is therefore no longer necessary for the base body and the driver to be made of the same material. Thus, the driver may for example be designed to be particularly elastic, whereas the base body may be made of a less or not elastic material, which allows the more robust design.

In addition, it can be provided that the driver is detachably attachable to the base body at an angle to the conveying direction. The angle is preferably different from 90 ° and particularly preferably has a value less than 90 °. The arrangement of the driver at an angle to the conveying direction allows the driver analogous to the European patent application EP 2 752 378 A1 can be used as a spring element for pressing push elements to be transported to holding adapter. For this purpose, a thrust element is arranged in particular at the end remote from the base body of the driver, as is also known from the European patent application EP 2 752 378 A1 is known.

In a preferred embodiment, a conveyor chain of a conveyor system for the transport of objects hanging on holding adapters, which has a plurality of, in particular interconnected, chain links, in part chain links, which are designed as push chain links according to the preceding explanations.

The invention also allows for an automatic checking and changing method for detecting and to perform changes of drivers to be replaced.

By an automatic testing device missing or defective carriers can be determined during operation and the maintenance personnel so the absence and possibly also the indication of the specific location are displayed so that they can be identified and replaced or change times can be scheduled.

In addition, the tester can be supplemented with a changing device which laterally pushes out the driver to be changed by inserting a new driver, with simultaneous introduction of the new driver, especially when the releasable connection is configured as a tongue and groove connection, dovetail connection or feather key connection. Thus, a fully automatic detection and change can be done.
