DESCRIPTION:
BRIEF SUMMARY
BACKGROUND AND OBJECT OF THE PRESENT INVENTION
The present innovation relates to a device for the insertion of transportation anchors into a casting mold for concrete parts, preferably into a casting mold for concrete pipes.
The weight of concrete parts is often so great that the laying is only possible with the aid of a lifting apparatus. This is particularly true for concrete pipes laid in the ground. In order to fasten chains, ropes or the like, at least one transportation anchor should be provided on the outside surfaces and must not stand out from the outside surfaces, because otherwise a considerable risk of breaking during transportation would exist.
Concrete parts are produced in a casting mold corresponding to their respective shape which is referred to in the pertinent branch as the concrete form. The transportation anchors have to be inserted in their right position before the liquid concrete is filled into the casting mold.
For inserting the transportation anchors support means are used whereby the tranportation anchor is held in the casting mold by magnetic forces. When the concrete is filled in it often occurs that the transportation anchors are displaced out of their desired position. The arresting means which are especially provided for the transportation anchors can then only be fastened to the head end of the transportation anchor with difficulty or not at all during laying. The companies that use the concrete parts then often file complaints. Furthermore, a reduction in efficiency can be seen in the way the transportation anchors are inserted in the casting mold in an installation which produces concrete parts.
The object of the present innovation is to develop a device of the initially described type which increases the efficiency of a machine producing concrete parts and works as automatically as possible and safely, so that the desired position of the transportation anchors to be cast is maintained precisely.
BRIEF SUMMARY OF THE INVENTION
This object is attained according to the innovation by providing a magazine to hold the transportation anchors to be inserted at disposal, wherein a multitude of transportation anchors can be stored with their longitudinal axes parallel to one another, an output device that can be moved perpendicular to the longitudinal axis of each transportation anchor between two terminal positions to deliver a transportation anchor each time to a gripper which grips the transportation anchor at its head end and holds it and which is attained to a sled which is displaceable in the direction of the longitudinal axis of the transportation anchor, by which means the transportation anchor can be inserted with its free end into the casting mold. It is now possible to keep a larger amount of transportation anchors on hand in the magazine for working.
Depending on the performance of the machine producing the concrete parts the magazine must be refilled in certain intervals. During production of a concrete part, the operating personnel do not have to take any measures to insert the transportation anchor into the casting mold, because the device works automatically. Care must only be taken that the magazine is refilled before it is completely empty. With the output device which can be moved perpendicularly to the longitudinal axis of the respective transportation anchor, a sure delivery to the gripper inserting the transportation anchor into the casting mold is guaranteed, because the transportation anchor offers a large working surface. Because the respective transportation anchor is taken over by a gripper, not only a sure delivery is guaranteed, but also an insertion in the right position into the casting mold. Because the gripper is furthermore attached to a displaceable sled, the control can be set in such a way, that the gripper only releases the transportation anchor after the casting mold is filled. If necessary, the gripper can continue to hold the transportation anchor during the setting period of the concrete filled in. Deviations from the desired position
