Problems solved by technology

[0015] The disadvantage of this design is that the construction of the swivel and displacement mechanism leads to a large height of the structure, which conflicts with the requirement of a good freedom of movement in the loading and unloading of workpieces
Furthermore, in this design it is not possible for the two drive motors to operate in a fixed manner relative to the beam

Embodiment Construction

[0030] Figure 1 shows an electronic transfer system 2 which functions to remove formed workpieces 3 from the final forming section 1 of a multi-slide transfer press or press line and deposit them onto one of the conveyor belts 4,5 . These conveyor belts 4 , 5 , which move continuously or clockwise in the direction of the arrow 6 , are used for stacking the prepared shaped workpieces 3 into stacking containers, which are not shown in more detail here.

[0031] In order to synchronize with the maximum press stroke rate during the stacking process, two conveyor belts 4, 5 running in parallel are used in this particular embodiment. The workpiece 3 shown is a large-area, rectangular shaped part. Therefore, during the transfer out of the final forming stage 1 or out of the lower die 7 , the workpiece 3 is rotated such that it is deposited longitudinally on the conveyor belt 5 . Since the conveyor belt 5 is not aligned centrally in the direction of the passage through the press, it...

Abstract

Method and related apparatus for generating an output signal with audio reverberation effect according to an input signal. In the invention, a constant echo interval is chosen, then a plurality of delay signals, which are delayed signals of the input signal, are generated such that a delay signal and its adjacent delay signal has a delay time equal to the echo interval; and a quantity of the delay signals is adaptively determined according to how many echo intervals are covered in an early reflection portion of the reverberation effect. These delay signals are low-pass filtered for forming the early reflection portion of the output signal, and comb filtering is performed on these delay signals for forming a late reverberation portion of the output signal.

Description

technical field [0001] The invention relates to a device for transferring and changing the position of blanks, shaped workpieces and paired parts, especially in the loading and unloading phases of a metalworking process with several machining stages and press lines. Background technique [0002] The production of workpieces that require multiple process operations, such as die forging or cutting, is usually produced on so-called multiple-slide transfer presses or press lines. The number of tools corresponds to the number of steps required for production. There is a transfer device between each step to transfer the workpiece from one processing position to the next processing position. In conventional designs of these conveyors, grippers or transport rails extending the entire length of the press are moved by cam-controlled drives. On these rails there are grippers or holding elements which hold the workpieces during their transfer. [0003] On the one hand, this type of d...
