Dosing machine for hard gelatin capsules

Abstract

The carousel (14) that carries the holder (4) with the product to be dosed, with the lower disc (1) fitted with peripheral sets of dosing holes (2) into which the static stations of plungers (7) insert and press in successive stages the doses of product, carries on board itself, on the periphery, the fixed bodies (11) and the radially moveable bodies (11') with seatings for supporting the tops (C1) and bottoms (C2) of the hard gelatin capsules. The lower bodies support extensions (111) that are oriented towards the centre of the carousel and that are used to close the lower ends of the said sets of dosing holes (2) in the successive stages forming the doses of product. Opposing members (15) are provided to support the moveable assemblies (111, 11') during the stages of formation of the product doses. With only one dosing disc (1) it is possible to form doses of product of different densities and masses and different heights by varying the heights of the sets of plungers, and ensuring that one station of plungers completes the filling of the dosing holes without pressing the corresponding quantity of product (Q4) as happened with the previous quantities (Q1-Q3). The chamber defined by the sweeper wall (10) and containing no product is provided with a plunger station (K5) that completes the pressing of this final quantity of product (Q4) and, if required, of the complete carrots of product isolated within the dosing holes, before a subsequent plunger station (K6) discharges these carrots of product into the capsule bottoms. The doses of product can be checked for mass by force transducers (T, T') fitted to at least the plungers of the final pressing of the doses and connected to the processor that controls the dosing machine.

Description

technical field [0001] The present invention relates to a disc-plunger metering device particularly suitable for packaging a quantity of loose granular material in a hard capsule or other container, which can be operated intermittently, and in this particular field to which the present invention relates, the present invention The invention relates to improvements that make such metering devices more reliable, accurate and easier to use when changing the volume of ingredients to be produced, as well as improvements that reduce product loss and eliminate wear on parts of the device. Background technique [0002] like figure 1 , 2 As shown in and 3, the prior art device is mainly composed of two carousel belts A and B on the vertical axis, they rotate in the same direction, for example, in the direction shown by arrow F and the amplitude of their intermittent motion is equal to that of the carousel belt The angle occupied by each section. Carousel B is used for forming ingre...

AI Technical Summary

Problems solved by technology

[0004] exist figure 1 , 2 In the known devices shown in 3 and 3, the following disadvantage is encountered: the ingredients pressed into the holes 2 of the disc 1 during the circular rotation of the disc rub against the fixed partial ring 3 and eventually produce a Dents through which some filler may be lost and which make ingredient dosing inaccurate

More filler may be lost through the gap between disc 1 and seat 11'

When the holes 2 containing the filling are positioned on the seat 11', these holes go over all the seats with the bottom of the capsule and may randomly scatter the ingredients in the bottom of the capsule, making the dosage inaccurate

Another disadvantage arises from the need to change the disc 1 when changing the dose of the ingredient to be formed, even if the dose is changed slightly

Attempts have been made to use discs with telescoping supports whose height can be varied as a function of the dose of ingredient to be produced, but when using bulk material that adheres to the handling device, since in this case the device would gets stuck and degrades its performance, so this design solution is unsuccessful
