The invention relates to an apparatus for removing successively conveyed similar objects, e.g. dough pieces, from a continuously moving conveyor on a substrate below the conveyor. The conveying end of the conveyor of the equipment is moved stepwise against the direction of travel of the conveyor by means of the conveying equipment, and the ejection head is taken to its starting point with a single pull after the removal event. The system has a switching device which moves with the end of the conveyor and is operated by the objects to be removed, and a second control device, independent of the objects to be removed, for controlling the step length.

An apparatus such as that described above is known from DE 1 273 419. It has fixed, similar pieces of rails and openings at the same distances along the trajectory of the object-conveying conveyor 2 60345. the discharge end has traveled a distance along the rail body and the opening. The length of each rail section then corresponds to the length of the object plus the distance between the objects on the substrate, whereby the division of the rows of objects removed on the substrate is determined to be fixed. Although this known apparatus fulfills its purpose perfectly and still removes irregularly placed objects on the substrate at exactly the same distances, certain difficulties arise when the apparatus has to be adapted to different lengths of objects and / or different distances of objects. This is when it is necessary to change the rail pieces and openings of the known equipment, which, above all with frequent changes, leads to annoying interruptions in operation.

In order to overcome the above-mentioned disadvantages, another photoelectric device is arranged behind a photocell-like switching device arranged at the outlet end of the conveyor in another known removal device at a distance corresponding to the desired distance between two successively removed objects (DE-AS 1 956 697).

The removal step for this hardware begins when the object starts the first photocell and ends when the object has passed the second photocell.

However, the distances between different objects are always the same in this system, but the length of the removal step still varies according to the length of the object. The latter, when the object is, for example, a piece of dough, is not always exactly the same, which makes it difficult to remove the dough pieces on a baking sheet or the like.

The object of the invention is to adapt the control of an apparatus such as the one mentioned above so that the stride length of the removal and at the same time the distances of the objects on the substrate can be changed without interruptions and modifications, but in this case the stride length and distances must be consistent.

According to the invention, this task is solved in such a way that the control device, which is independent of the objects to be removed, is a timer which can be started after the switch-on device is actuated and which stops the conveyor outlet after a set time. Thus, in order to change the step length, the 5 60345 only needs to change the time setting of the switching clock, which can be performed without interruptions. If the dimensions and / or distances of the objects on the drop platform often change, the necessary changes can even be made automatically, for example by means of program control.

An embodiment of the invention is shown in the schematic diagram and will be described below.

The apparatus consists essentially of an endless conveyor 1 passing over the movable end rollers 2, 3 and fixed pivot rollers 4 · 5 »6, 7 and a paired endless chain-like conveying device which passes over the sprockets 9, 10, 11, 12 and to which chains the end rollers 2, 3 are attached. The motor 13 drives the conveyor 1 continuously. The second motor 14 drives the chains 8, so that - from the state shown - formed by the end roller 2 of the conveyor 1 is pushed step by step the outlet indicated by the arrow against the travel direction of the strip. Arbitrarily consecutive objects carried by the conveyor 1, e.g. dough pieces 3 », then leave at exactly the same distances on the base 16 below the conveyor 1. At the end of the removal, when the tray 16 thus has a full row of dough pieces, the direction of rotation of the motor 14 detectable initial state.

At the outlet end of the conveyor 1 and moving with it there is a switching device similar to a photocell, a capacitive limit switch or the like 17 *

As soon as the dough piece 13 conveyed by the conveyor 1 raises the coupling device, the motor 14 starts and the chains 8 move the outlet end of the conveyor 1 against the direction of the belt, whereby the dough piece 13 enters the base 16. Simultaneously with starting the motor. After a set time, which time, when the chains 8 move at a constant speed, corresponds to the distance traveled by the end roller 2 during the drop step, the motor is stopped and the conveyor outlet movement stops until the next dough piece 13 raises the coupling device 17.

The starting point of the outlet end of the conveyor 1, as can be seen from the drawing, is determined in a manner known per se by a limit switch acting on the motor 14, not shown here. Correspondingly, the change in the direction of movement of the discharge head is also controlled after the end of the complete discharge series.

The control according to the invention can be used particularly advantageously in cases where the dough pieces 15 are conveyed in rows opposite each other but removed at regular intervals in rows on the substrate 16. It is only necessary to ensure that the discharge operation alternates This can be done, for example, by means of an additional limit switch located at a distance corresponding to the first limit switch and controlled alternately with it.
