Definitions

the invention relates to a device for producing compacts, preferably a tablet machine according to the preamble of claim 1.
the object of the invention is to remedy the abovementioned situation.
the dosage should be further improved and the appearance of black Stains on the surface of the tablet or tablet should be minimized.
Claim 1 is accordingly based on a device for production of compacts and in particular of tablets, according to the preamble of Claim 1 of the filling shoe via a servomotor opposite the surface of the rotating die table with adjustable height.
the distance between the base plate of the filling shoe and the die table so far to optimize that depending on the composition and grain of the pressing material loss of material can be individually minimized.
the distance can be chosen so that there is no abrasion of the Sealing strips and thus to form the black spots to be avoided is coming.
the base plate of the filling shoe can be placed on one in the machine frame arranged motor height-adjustable base.
a measuring device can be provided, by means of which the distance between the base plate of the filling shoe and the surface of the rotating die table is measured. This means that the setting values are based on the product quality on the one hand, it can be monitored and, on the other hand, it can be recorded in a reproducible manner.
an output device for the measured values can be used.
the gap width can be adjusted also by means of a control loop in which the gap width is used as the controlled variable is adjustable, even if guaranteed during the rotational movement Differences in height occur on the rotating die plate.
a machine frame 12 there is not a die plate 14 over one here shown motor in the direction of arrow a in incremental rotation. This incremental rotation results in one not shown here in each case Press chamber for receiving the filling material to be pressed into its receiving position brought.
the recording position is defined by a stationary filling shoe 16, through which the filling material to be pressed is filled.
a filling shoe for example a paddle pad 16 known in the art is used become.
the agitator paddle shoe 16 is via its base plate 18 on a base 20 mounted that it rotates in the manner shown in the figure Die plate 14 is positioned. In this partially overlapping position there is a gap 22, the width of which depends on the distance between the underside of the Bottom plate 18 of the filling shoe 16 and the surface of the rotating die plates 16 depends.
the base 20 is used to adjust the width of the gap 22 adjustable in double arrow direction b via a highly accurate servomotor 24.
the engine 15 and the transmission are however so designed that an adjustment of the width of the gap 22 to 100th mm possible is.
the width of the gap 22 can here in a not shown in the figure Be measured by means of a measuring device and by means of a Output device can be displayed graphically. This allows each optimally set values can be recorded reproducibly. Instead of a graphic The values can also be stored in an electronic memory become.
the width of the gap 22 can also be used as a controlled variable of a control loop serve. This allows an optimal distance between the filling shoe 16 and the Die plate 14 are set, based on empirical values for certain pressing feed materials in an otherwise well-known machine are based.
the application of the device according to the invention is not for pressing Tablets, but can be limited to pressing any compact in extend such compression devices.
