Problems solved by technology

Precisely in older injection molding machines, the problem arises that the opening stroke is carried out without tolerance, which makes it difficult to pick up the workpiece with the gripper
Inaccurate gripping of workpieces can lead to production defects or production interruptions
Likewise, when handling injection molded parts by suction nozzles, for example when dismantling buffer stacks, inaccurate gripping can lead to malfunctions in the production process

Embodiment Construction

[0027] according to figure 1 The injection molding machine 1 is shown with the mold halves 2 , 3 open. The robot 4 enters the opened tool halves 2 , 3 for removal of the workpiece 5 . Position A of the robot 4 is entry into the open mold, wherein in position A the robot 4 has reached the point for releasing the measurement of the reference plane 9 .

[0028] In position B, the robot 4 is located in the region of the workpiece 5 .

[0029] The automatic manipulator 4 can be moved by means of a drive which can be acted upon by a programmable control and regulating unit. The robot 4 is provided with a gripper 6 and has at least one suction nozzle 7 . A programmable control and regulation unit 10 is provided in the robot 4 , which optionally has a separate sensor evaluation unit.

[0030] A distance measuring device 8, such as a TOF sensor, is arranged in the gripper 6 of the automatic manipulator 4, and the distance measuring device is used to detect the distance a from the g...

Abstract

The invention relates to a device for transferring and / or handling and transporting workpieces (5), in particular for removing injection-moulded objects from an injection molding machine, wherein the automatic handling machine (4) is provided with a programmable control and regulation unit (10), the automatic manipulator is provided with a gripper (6), and the gripper has at least one suction nozzle (7) for grabbing or sucking the workpiece (5). The distance measuring device (8) is arranged in the gripper (6) of the automatic manipulator (4), and the distance measuring device is used to detect the distance (a 1 +a 2 ) for the preferably movable tool half ( 2 ) with the workpiece ( 5 ), for example. The measured values ​​of the distance measuring device ( 8 ) are supplied to the control and regulation unit ( 10 ). The distance measuring device ( 8 ) can be an optical time-of-flight-measuring device, in particular a time-of-flight (TOF) sensor.

Description

technical field [0001] The invention relates to a device for transferring and / or handling and transporting workpieces, in particular for removing injection-moulded objects from an injection molding machine, wherein the automatic handling machine is provided with a programmable control and regulation unit, the automatic handling machine A gripper is provided which has at least one suction nozzle or gripper for gripping or suctioning the workpiece. Background technique [0002] The problem of removing workpieces from injection molds has been raised several times. Especially older injection molding machines or machines of the Asian construction type open the injection mold to a slightly different degree each cycle. Likewise, the operator of the injection molding machine can adjust the mold opening position at the control unit in any operating mode. Reliable gripping of the injection molded parts by means of the grippers on the removal robot is therefore not guaranteed. There...
