Abstract

The handling device is intended for unattended workplaces with a technological pallet in automatic production systems. It consists of a fixed stand equipped with two roller tracks and at least one feeder, which moves the technological pallet from the stand to the machine tool fixture and vice versa with multiple strokes. The technological pallet is inserted and removed from the handling device by an inter-operation transport means

The invention solves the manipulation device of the automatic exchange of technological machine tool pallets.

For chip machining, workpiece machining is used in machine tool technology pallets. On the technological side, the workpiece is fixed and is inserted into the machine tool chuck with the bracket. Several methods of handling are currently used in the automated manufacturing system for loading, unloading and returning pallets. Other ways can be divided into: a) solutions not used for manipulation of the machine tool drift b) solutions utilizing the drift movement with the switch.

A solution that does not use adit with a machine tool switch is based, for example, on a pallet exchange from one central location. At this point, the pallet is inserted, picking and machining in the machine tool. Such operating handling devices interconnecting machine tools and intermediate conveying are displaceable or rotatable. No intermediate stock for machining is required for the displacement handling device. In addition, the displacement devices, due to an inappropriate delivery system, occupy a larger area than is needed. At the time of manipulation, the machine tool is waiting for interoperative transport. The rotatable embodiment of the device creates the necessary intermediate stock but occupying handling surface and requires more complex mechanics.

Solutions utilizing the adit movement with the clamp are based on the fact that the necessary intermediate storage is created in two places by the pre-machine and the manipulation between them is performed by the machine table itself with the clamp. Handling the pallet into these locations is carried out by two separate displacement manipulation devices. The disadvantage of the solution is a large built-up area in front of the machine and the complexity of the moving devices.

Up to now, the handling devices used for the automatic exchange of technological pallets have always only dealt with one automatic interconnection, namely the machine tool - the manipulation device and they do not have the interconnection for inter-operation transport, or they merge by adding another complicated mechanical device.

The above-mentioned disadvantages of hitherto used manipulation devices are removed by a manipulation device for automatic exchange of technological pallets in machine tools consisting of a fixed stand, roller tracks and a feeder, the base of which is that the fixed stand is fitted with two roller tracks formed by two rows roller rollers, with at least one feeder placed on the fixed stand. Cylindrical rollers are provided with a conical collar from the outside. Alternatively, loose cylindrical rollers may be associated with the rollers, the axis of which coincides with the axis of the cylindrical roller tracks an obtuse angle.

The device according to the invention solves the insertion of the removal of the technological pallet from the clamping machine and the machine and the transfer and take-over of the pallet from the in-service transport by a single device, the main advantage of which is the minimal built-up area and simple construction, replacing the set of devices used up to now. The application of the equipment is most common in automated production systems. An example of an embodiment of a device constructed according to the invention is shown schematically in FIG.

The device consists of a fixed stand 1, which is fitted with two roller tracks 9 and a feeder 5 arranged in the center between the roller tracks 9. The roller tracks 9 are fitted with cylindrical rollers 10 with conical beads 6.

The pulleys 10 with tapered shoulders β can be replaced by assigning free roller pulleys whose axes have an obtuse angle to the oscillating pulleys 10.

The means of in-service transport places the process pallet 8 in one of the free roller tracks 9. The identification of the technological pallet 8 and the axis of the roller tracks 9 in the case of inaccuracies in the stopping of the transport operation is transferred by the conical beads 6 or by two rows of free cylindrical rollers. which provide an obtuse angle to the rollers of the rollers 19. The machine tool clamp 7 is moved to the axis of the roller track 8, into which the technology pallet 8 has been laid. The conveyor 5 moves the machine pallet 8 by repeatedly moving it from the machine to the machine tool clamp 7. The second machine pallet 8 is placed on a free roller track 9. After machining the machine located on the machine pallet 8 in the machine tool 7, the machine tool switch 7 is moved to the free-roll track 9. Feeder 5 moves the pallet 8 from the fixture machine 7 to the handling device. The chuck moves to the axis of the roller track 9 with the second process pallet 8 supplied by the co-machine. The feeder 5 moves the pallet 8 into the machine tool clamp 7. During processing of the intermediate conveyor blank, the pallet is removed by the finished workpiece and the cycle is repeated.

The invention is suitable for flexible manufacturing systems operating with technological pallets.
