Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention involves repeatedly lifting a tangled block of assembled parts, repeating the lifting until the block of assembled parts separates, and removing the separated assembled parts. The present invention relates to a method for separating entangled or intertwined solids into pieces for discharge, and an apparatus for carrying out this method.

PRIOR ART A method of this type is known from U.S. Pat. No. 3,118,564, in which a mass of coil springs is repeatedly removed from a support in order to separate entangled coil springs. It is lifted and dropped, thereby ejecting the separated coil springs. In that case, this process is carried out until the nodules are finally separated. For this purpose, a mass of entangled coil springs is placed in a reservoir, which reservoir is surrounded by an electrical winding. The windings are periodically loaded with a current, resulting in the formation of a magnetic field within the nodule, which field is opposite to the magnetic field of the coil. As a result, depending on the frequency of the current load on the coil, the nodule is lifted as a whole, and when the current is interrupted, it falls again onto the support provided below the storage tank. The reservoir itself is open downward and supported on legs;
An outlet is formed between the legs for the discharge of the coil spring separated by the process.

A disadvantage of this known method is that the mass is always lifted up as a whole and dropped as a whole onto a support, on which a possibly separated helical spring may already be present. Therefore, there is a risk that the coil spring, which has already been separated, may be reattached to the mass or lifted up again. Already for this reason, the separation efficiency with this known method is relatively poor.

Moreover, the magnetic field generated within the nodules causes the nodules to be fixedly brought together to form a virtually undeformable block, so that the efficiency when separating the individual coil springs is almost zero. This known method is therefore virtually unsuitable for individual separations and cannot even be used in practice.

Assemblies for mass production, such as springs, contacts, electronic elements, pins, tubes, hooks, discs, rings, etc., are placed in a storage tank for individual separation and then placed in a storage tank or stirred by a stirring device. It is also already known to move the motor through a flow medium or by means of a flow medium, such as blown air and injected fluid, and to discharge through an outlet adapted to the dimensions of a single assembly. However, this type of method has only a very low separation efficiency and can only be used effectively in the pre-relaxed state of the assembly nodules. Moreover, the implementation of this method requires complex and uneconomical equipment, the operation of which is highly trouble-prone.

Additionally, intertwined or intertwined assemblies may be removed from vortex chambers, vibrating stations,
It is also known to separate by guiding by linear conveyors, entraining belts, brush conveyors, guide surfaces, separating edges, deflectors, sheave belts, chutes, balancing rods, collision surfaces, etc. When properly combined, it is possible to separate highly intertwined assembly parts from each other and break up the entire assembly mass.

Problems to be Solved by the Invention It is an object of the invention to provide a method and a device with which highly entangled or intertwined assembly parts can be separated individually more effectively.

Means for Solving the Problems The gist of the method of the present invention, which solves the above problems, is to grasp the tangled mass of assembly parts from above, hook it up, lift it, and release it at a predetermined position. be.

The gist of the device according to the invention for carrying out the method according to the invention is that it is provided with a storage tank for the entangled mass of assembly parts, which storage tank has an outlet leading to a removal point for the separated assembly parts. and is provided with a device for repeatedly lifting and lowering the nodules on a support, this device consisting of a gripper that can be lowered into the area of the support. It is in.

Effects and Effects of the Present Invention According to the method of the present invention, the nodules of the assembled parts are grasped from above, hooked and lifted, and released at a predetermined position. When it is pulled vertically, it becomes thinner, and when it is released and supported on a support table, it is compressed vertically and becomes thicker, so that the nodule loosens with each cycle of tension and compression, and when it is lifted, it is separated into pieces. Or a slightly tangled assembly is left on the support. The assembly parts separated in this way are immediately discharged from the outlet and fed to a removal point or to a further subsequent separating device. Depending on the type and strength of the assembly, the separation process can be facilitated by releasing the lifted nodule to fall onto a support or by shaking it. This is because the inertial force of the nodule generated when the nodule hits the support base or when the nodule vibrates is used to disentangle the assembled parts.
This dropping or shaking of the nodules is not absolutely necessary and may be avoided in the case of sensitive assemblies to avoid damage. The separated assembly parts are
Since it is ejected while the nodule is being lifted, a situation in which the separated assembly parts become entangled with the nodule again when the nodule is lowered is avoided.

The inlet of the take-off point, the conveyor leading to the take-off point, or another separating device, sorting device, etc. can be connected directly to the outlet of the device according to the invention. The point is that the gripping claws can automatically grasp the nodules charged into the storage tank from above, lift them up and release them again. The supply of fresh nodules can take place in any manner, for example via an openable side wall flap of the reservoir.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The apparatus shown in the drawings comprises a storage tank 1 for the assembly parts to be separated, the bottom of which forms a chute 3 which is guided towards a slit-shaped outlet 2 . A drivable roller-like brush 4 is provided in the region of the outlet 2, which brush forms a device which serves to separate the individual assembly parts. In order to achieve uniform discharge and to control the discharge rate, the effective length of the brush can be varied, for example by changing the brush. The assembly parts discharged by the brush 4 through the outlet 2 fall via the impact and deflection body 5 onto the sliding surface 6 and are then transferred onto the linear conveyor 7 . The linear conveyor 7 supplies the assembly parts in a completely separated state to a removal point (not shown).

In order to enable this device to separate even large clusters of assembled parts that are strongly entangled, a lifting mechanism 8 is disposed opposite to the storage tank 1. It is possible to enter inside. The upper region of the assembly nodules inserted into the storage tank 1 via the openable side wall flaps 10 of the storage tank 1 is gripped by gripping pawls 9, by means of which the assembly nodules are moved into the brush 4. and chute 3, and then lowered onto this support again and released, or released and allowed to fall before being lowered. This process continues until the entire mass of assembly parts is separated, and the individual assembly parts separated during this process are caught by the brush 4 and discharged.
By suitably selecting the effective length of the brushes 4, a uniform amount of separated assembly parts is always ejected through the outlet 2, even when a very large number of assembly parts suddenly hits, so that a significantly larger Separation efficiency is guaranteed. Because the assemblies that are entangled or stuck together can be lifted up and released again by the gripping pawls 9, even highly entangled assemblies are separated.
