Description

Conveyor device for piece goods, in particular arranged on pallets

The invention relates to a conveying device for piece goods, in particular arranged on pallets with a track formed for example by rollers and movable along the conveyor Drivers, one behind the other on a drive part that can be moved in the longitudinal direction of the track mounted to be movable transversely to the conveying direction from a driving position into a non-driving position are and with each of which a mounted on the drive part, lying in front of it in the conveying direction and in the movement path of the piece goods protruding feeler member is mechanically connected in such a way that when it runs into

of the sensing element on a piece of goods, the driver moves into the non-entrainment position.

It fet a conveyor known in which the leg feed grabbing the piece goods by control levers, the feeler arms of the Scan forecourt of the respective driver engagement position, are actuated to the feed device to be disengaged if the forecourt on the running track is occupied. The uterine arms and drivers are connected to one another by a tension spring, which is why these two organs must be close to each other. The pieces to be collected can therefore not keep a distance and the carriers cannot attack on the back, but only on the front part of the piece goods, which is why only very specific piece goods can be transported with it. Leave with this device So the piece goods to be moved are only lined up with a stop, but not with spacing gaps. In addition, the connecting spring is also due to the high risk of breakage and signs of fatigue disadvantageous.

The invention is based on the object of providing a conveying device of the type described at the beginning to be trained in such a way that the Mitneller control also has a simple structure and reliable function a request for piece goods with gaps is possible.

In the case of a conveying device for piece goods, in particular arranged on pallets, with a, for example track formed by rollers and carriers movable along the conveying device, the one behind the other on a Trdlebteil movable in the longitudinal direction of the track to the conveying direction from a sewing position in a non-entrainment position are movably mounted and with each one on the drive part stored, in the forward direction lying in front of it and protruding into the movement path of the piece goods is mechanically connected in such a way that when the sensing element is loaded onto a piece of goods, the driver moves into the Moved non-entrainment position, according to the invention, the tactile organ (via a linkage or the like.

The linkage can in a simple manner by a rod, preferably a push rod and a be formed with this articulated, hinged to the support part lever. That is useful Rod with the end facing away from the sensing element on the preferably angular, on the drive part hinged lever, which is articulated to the driver, so that a smooth-running Linkage connection between the sensing element and driver is achieved. The angle lever is an advantage of the ixKX with the end of one arm on the deirilriebteil articulated, the end of the other arm being articulated to the driver and in between the pivot point of the rod lies; as a result, the arm articulated with the driver can the angle lever are arranged approximately in an extension of the rod in advantageous catfish. Appropriate the arrangement is made so that In the

Carry-along position two arms of the angle lever for the feeler element and the angle lever connected to this via the rod are approximately parallel.

A further simplification in the connection of the tactile element with the driver results when the driver, preferably designed as a one-armed lever, with a pivot pin in a slot of the angle lever engages.

The sensing element can be provided in a very simple manner only with a stop cam for scanning if the driver is spring-loaded or weight-loaded towards the take-away point. Appropriate 1st a spring is hinged to the tactile organ.
