Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handling device in a plastic injection molding machine having a transport arm with a replaceable gripping mechanism for the removal of parts from the injection molding machine.

BACKGROUND OF THE INVENTION Handling devices of this type, which are equipped with suitable control devices, are used in particular for removing workpieces (injection molded parts) from the tooling of injection molding machines and into material storages. It is used to deliver workpieces. Depending on the type, shape and size of the workpieces produced on the injection molding machine, an adapted gripping mechanism must be fastened to the transport arm. Replacing such a gripping mechanism is
It is cumbersome, requires a lot of work, and consumes time.

This is because not only does the gripping mechanism itself have to be removed from or fixed to the transport arm (which, as usual, requires a number of loosening and tightening screws). , of the drive and control devices necessary for carrying out the operation of the gripping mechanism,
This is because the connection of the gripping mechanism with the associated element must be released or re-established.

Problem to be Solved by the InventionThe invention is therefore based on the problem of simplifying the exchange process in such a way that it can be carried out essentially automatically and without complicated manual operations. It is.

Means for Solving the Problem In order to solve this problem, the handling device according to the invention is provided with a coupling device between the transport arm and the gripping mechanism, in which a coupling device is provided between the transport arm and the gripping mechanism. , all in addition to a locking device for a releasable rigid connection with the gripping mechanism.
It is characterized in that the simultaneously pluggable and removable joints required for the releasable connection of the energy and signal conducting elements are integrated.

A magazine device is provided in which this arrangement has a holding element for the gripping mechanism, in which case insertion and removal of the coupling takes place by relative movement between the transport arm and the gripping mechanism holding element; On the other hand, it is expedient for the locking device to be operable automatically or manually.

EXAMPLES Hereinafter, the present invention will be explained based on FIGS. 1 to 1j of the accompanying drawings showing examples thereof.

First, in Fig. 1, a horizontal rail guide is indicated by /, on which a carrier is guided so as to be movable horizontally, but this carrier is movable vertically. It supports the transportation arm 3. As will be explained in more detail below with reference to FIG. 1, the transport arm 3 is located in a first position a in the region of the tool holder of the injection molding machine, the rest of which is not shown, and in a workpiece storage. 6 and a third position C in the area of the gripping mechanism magazine device 5. The displacement movement of the carrier and of the transport arm 3 is effected by means of an actuating device, which is not shown in detail and is provided with a suitable simple or computerized control system.

A first portion a of a coupling device 7 is fixed to the lower free end of the transport arm 3, and the other portion 7b of the coupling device is
It is attached to the carrier part a of the gripping mechanism g, which is only shown schematically. The coupling device @7 is provided with a locking device t. As shown in Figures 2 (and 1I), the locking device 9 can be actuated, for example by water or air pressure, and it may also be useful for the purpose to be actuated or deactivated automatically. And in this case, both of the fitting parts? Is the tightening arm ya pivoted to a a joint part in the operating position? Grasp tlft from below and both joints? a. Avoid 7bi separation. Third
As shown in the figure, the locking device may also have a manually operable tightening lever qk11.

The handling device described above operates as follows. In the tool device DA of the injection molding machine, the molded product W is finished, and the gripping mechanism g connected to the transport arm 3 is connected to the first
For example, a conveyor bell (as shown on the right in the figure)
transported to a workpiece storage member 6 formed as 6a;
It is also assumed that the gripping mechanism is correspondingly replaced by other gripping mechanisms for the production of other types of workpieces.

After opening the gripping mechanism and correspondingly releasing the workpiece W,
The coupled gripping mechanism t' (the provided transport arm 3 is moved to the magazine device 5, where the gripping mechanism t is
It enters into the semi-vacation 5a attached to it. Subsequently, the locking device 9 is opened and the coupling device 7 is removed by upward movement of the transport arm 3 (center position in FIG. 7). The transport arm 3 is now in a similar half 5a,
moved onto the new gripping mechanism g to be replaced;
In this case, the coupling 7 is inserted by lowering the transport arm 7 and secured by operating the locking device. In this way, the transport arm 3 equipped with a new gripper wt is
Thereafter, the workpiece to be newly manufactured is withdrawn from the tooling device ψ and transported by the gripping mechanism j to the workpiece storage 6 until it has to be replaced again.

All conduits, conductors, etc. necessary for the control or operation of the gripping mechanism t and for the feedback of the signals emanating from them are provided with suitable connections inside the coupling device 7; The connector is the joint device 70 and both members 7fL.

When 7b is moved in the above-mentioned opposite or mutual direction, it is automatically inserted or removed. Mechanical forces, electrical energy or signals, or pneumatic or hydraulic media can be transmitted by means of such connections. A coupling device is shown that includes a power or media connector. Therein, IO is a centering pin that ensures correct connection engagement; // is a connector for electrical signal conductors; /2 is a connector for electrical energy conductors; /3 is a connector for electrical energy conductors; Ill indicates a compressed air or vacuum connector, and llI indicates a water pressure connector, respectively.

In such a relative movement of the parts a, 7b, the pluggable or removable connector automatically
It is believed that they are known per se and do not require any more detailed explanation here.

Effects of the Invention According to the present invention, as described above, all the connectors provided between the transport arm 3 and the gripping mechanism g, which are necessary for controlling or operating the gripping mechanism g, are included therein. Due to the above-mentioned formation of the integrated handling device of the coupling device, the replacement of the gripping mechanism is possible without labor-consuming operations.
This takes place within a short time, so that the downtime of the injection molding machine when changing the gripping mechanism can also be significantly shortened.
