Problems solved by technology

This in turn can lead to tablet jams in the tablet discharge and shut-off of the rotary tablet press due to switch failure
This significantly limits the usability of the rotary tablet press and the manual effort for the operator to eliminate faults is high
Therefore, the housing of the rotary tablet press needs to be opened in order to eliminate tablet jams, which leads to increased health risks, especially in the case of toxic extrusion materials

Embodiment Construction

[0031] Unless otherwise stated, the same reference numerals in the figures denote the same objects.

[0032] exist figure 1 The rotary tablet press shown in includes a rotor with a mold disk 10 having a plurality of cavities 12 rotatably driven by a rotary drive not shown in more detail. The cavity 12 can be formed, for example, by drilling the mold plate 10 . Further, the rotor includes a plurality of upper punches 14 and lower punches 16 which revolve synchronously with the die plate 10 . In this case, a pair consisting of an upper punch 14 and a lower punch 16 is each assigned to a cavity 12 . The axial movement of the upper punch 14 and the lower punch 16 during the rotation of the rotor is controlled by an upper control curve element 18 and a lower control curve element 20 . Furthermore, the rotary tablet press comprises a filling device 22 having a filling chamber 24 . Furthermore, the filling device 22 comprises a funnel-shaped filling material reservoir 26 which is...

Abstract

The invention relates to a switch of a tablet discharge part of a tablet press, wherein a control device and a drive device are provided, and the drive device makes the switch switch between a first switching position and at least one second switching position according to a switching signal of the control device. To move between two switch positions, at least one sensor is provided to detect the arrival of the first switch position and / or at least one second switch position by the switch, the detection signal of the at least one sensor is applied to the control device, and the control The device is designed to output, in the event of a switching signal for moving the point switch from an initial switching position into a target switching position and no detection signal for the arrival of the target switching position, an output for partially moving the point switch. Or completely return the switching signal for the movement into the initial switching position, and then output the switching signal for moving the switch back into the target switching position. The invention also relates to a rotary tablet press and a method for operating a switch.

Description

technical field [0001] The invention relates to a switch of a tablet press, in particular of a tablet discharge section of a rotary tablet press, wherein a control device is provided, and wherein a drive device is provided for making the switch according to the control The switching signal of the device moves between a first switching position, in which the tablet is delivered to the first tablet output, and at least one second switching position, in which the tablet is delivered For the at least one second tablet discharge, at least one sensor is provided for detecting the arrival of the first switching position and / or the at least one second switching position by the switch. [0002] Furthermore, the invention relates to a method for actuating a switch of a tablet discharge of a tablet press, in particular of a rotary tablet press, in which method the switch is switched between a first switch position and at least one second switch position. movement between two switch posi...
