Abstract

The apparatus makes possible the automatic successive drawing-off of samples of liquid from different containers into correspondingly different bottles. The apparatus has a pipe (4) which is connected at one end to a chamber (5) and at the other end to one end of a tube (3). The tube (3) has an aperture (17) in its wall in the region of its other end and can be moved longitudinally through a stroke (H) which is sufficiently large for the said aperture (17) to be situated in the bottle (14), into which the sample of liquid is to be drawn off, when the lower end of the stroke is reached and for the aperture (17) to be situated in a cavity (19), into which opens out one end of a second pipe (1) which is connected at its other end to a low-pressure source, when the upper end of the stroke is reached. The chamber (5) is penetrated by a slide (7) which is connected to the tube (3) in such a way that the said slide (7) connects the chamber (5) to a container (B), which contains the liquid to be drawn off, when the upper end of the stroke is reached and to a space, in which a pressure prevails which is greater than the pressure prevailing in the second pipe mentioned, when the lower end is reached.

Description

(54) APPARATUS FOR AUTOMATIC FILLING OF LIQUID
SAMPLE CONTAINERS
(71) We, WALTER JANSKY TANK
und Apparatebau, a Kommanditgesellschaft
of Taubenstrasse 25-43, D-4407 Emsdetten,
West Germany, do hereby declare the
invention for which we pray that a Patent
may be granted to us and the method by
which it is to be performed, to be particular
ly described in and by the following state
ment:
The invention relates to apparatus for
automatic bottling of fluid samples taken
successively from various containers into a
corresponding number of bottles.
It is known that with this type of appar
atus, measures must be taken to ensure that
fluid samples are not contaminated by the
residues from previous bottling or by any
other materials. In such apparatus interme
diate containers are provided to receive
fluid, as well as a pump which may be
switched on and off at each sampling opera
tion, forwarding the fluid under pressure
into a metering arrangement, and a com
pressed air feed for the purpose of cleaning
the apparatus after each sampling opera
tion.
The object of the invention is to provide
apparatus for automatic successive bottling
of fluids from various containers into a
corresponding number of bottles, which is
simple and can be cleaned automatically
after each sampling operation without the
introduction of an additional medium.
According to the invention there is pro
vided apparatus for automatic bottling of
fluid samples successively from various con
tainers into a corresponding number of
bottles, wherein a first duct is connected at
one of its ends to a chamber and at the other
of its ends to one end of a tube, near the
other end of which tube an aperture is
provided in a wall thereof, the tube being
movable longitudinally through a stroke of such a length, that the said aperture is
located, in use, within a bottle on reaching the lower stroke-end and is located within a compartment on reaching the upper strokeend, into which compartment one end of a second duct leads, whereas the other end is connected to a negative pressure source, the chamber being traversed by a ram which is connected with said tube in such a manner, that on reaching the upper end of said stroke, in use. it connects the chamber with a container holding the fluid to be sampled and on reaching the lower end of the stroke connects it with a source of pressure greater than the pressure within said second duct.
The arrangement is preferably such that said tube, to which said first duct leads, is in the form of a double-tube, with an inner tube open at its ends, with one of its ends passing through the wall of the outer tube of the double tube, at a distance from said aperture in the wall of the outer tube. which is substantially equal to said stroke of said tube. Advantageously the double tube is in the form of a filler tube. the outer tube being closed at its end opposite to that at which it is connected to said first duct and being pointed. and the inner tube passes through said end of the outer tube and being pointed at its end.
The ram of the apparatus is preferably in the form of a tube connected mechanically with the first duct, with side openings spaced apart by a distance corresponding to the stroke. and between which said tube is closed against any flow, a lower part of said tube leading. in use, to the container holding the fluid to be bottled, and an upper part leading to atmosphere or into a compartment under a pressure greater than that within the second duct. Furthermore, beneath said chamber a further chamber connected with the second duct and also traversed by the ram is located at such a distance, that when the ram reaches the lower end of the stroke. a lower one of said side openings of the ram is located in this further chamber.The connection between the outer tube of the double-tube and the ram is preferably such, that the stroke of the double-tube, in use, in the direction of the bottle only commences, after the ram has blocked the connection between said chamber and the container holding the fluid to be bottled.
Figures 1 and 2 show two different working positions of apparatus constructed according to the invention.
The apparatus as illustrated serves to bottle samples of fluid from containers B into bottles 14, more particularly for the purpose of bottling a sample from a milk container B into a bottle 14.
The apparatus comprises a fixed duct 1, connected at one end with a container under negative pressure or with the intake end of a pump. The other end of the duct 1 leads into a hollow compartment 19 of a stationary end-piece 2. From the duct 1 another duct la branches off leading into a lower chamber 6 of a fixed component 9 of the apparatus. Above the chamber 6, component 9 has an upper chamber 5 to which is connected a duct 4, having a filler-needle 3, in the form of a double-tube. at its other end, the part secured to the filler-needle moving axially thereto. A small inner tube 18 is located along the axis of the outer tube of the filler-needle 3, passing through a front closed end of the filler-needle and being pointed at its extreme forward end 18a by means of a slanting cut.An upper end of the small tube 18 is curved in relation to the side wall of the outer tube of the filler-needle where it has an aperture 18b open to the outside. In the vicinity of its point the outer tube of the filler-needle 3 has a side-aperture 17 in its wall.
The filler-needle 3 and the part of the duct 4 immediately connected to it. which may be in the form of a hose. can be moved through a stroke H by means of a piston rod 11, of a pneumatically- or hydraulicallyactuated piston within a cylinder 10, the rod 11 being connected to a cross-head 13. The stroke is in the longitudinal axis of the filler-needle 3. and substantially equal to the distance between apertures 17 and 18b.
Through the two chambers 5 and 6 and seals for sealing off in relation to component 9, passes a tube 7 connected with the cross-head of the piston rod 11 and consequently movable in the same manner as the filler needle 3. The tube 7 has a side aperture 16, leading into chamber 5 when the tube is in the position illustrated in
Figure 1, i.e. the side aperture 17 of the filler-needle 3 leads into the hollow compartment 19. A further aperture X is located in the sidewall of the tube 7. spaced from the aperture 16 by a distance equal to the length of the stroke H. The tube 7 is closed by an insert 7c between the apertures 16 and 18, this part of the tube 7 constituting a ram traversing the chambers 5 and 6. The lower end of the tube 7 is in the form of a hose 7a and leads into the container B.
The end of the crosshead 13 moving the filler-needle is not securely fixed to it, the end of the crosshead 13 being located between two flanges 12 and 12a, which are arranged in such a manner that on the downwards stroke of the cross-head 13 the filler-needle movement only commences after the aperture 16 has moved outside the chamber 5, so that chamber 5 is consequently no longer connected with the container B.
The arrangement as shown operates as follows when taking milk samples from milk churns.
The hose 7a is introduced into a container
B. As a result of the negative pressure in duct 1 which is also applicable to chamber 5 as a result of the duct 4 connected by aperture 17 with duct 1, milk is drawn from the container B through the hose 7a into chamber 5, duct 4, the filler-needle 3 and from thence by way of aperture 17 also in duct 1. The crosshead 13 is then moved downwards bv means of the piston rod 11.
The tube 7 is then promptly moved downwards by the same amount, being connected to it. so that the aperture 16 moves outside of chamber 5. It is only after this has taken place. that the right-hand end of the crosshead 13 butts against the flange 12. The tube 7 as well as the filler-needle 3 together with the adjoining part of the duct 4 is then moved in a downwards direction. The point 18a and the front end of the filler-needle 3 then pierce a closure 15 of the bottle 14. At the end of the downwards stroke H. the side aperture 17 of the filler-needle 3 lies inside the bottle 14 and the aperture 18b of the small inner tube 18 is inside the hollow compartment 19. At the same time the aperture 16 of the tube 7 lies inside the chamber 6 and the aperture 8 of the tube 7 lies inside the chamber 5. This condition is represented in Figure 2.
In this condition, the negative pressure is transmitted through the duct 1, the hollow compartment 19 and the small tube 18 to the inside of the bottle 14. As a result thereof milk is drawn into the bottle 14, out of the inside of the filler needle 3, the duct 4 and the chamber 5, since this is now connected by way of aperture 8 with the duct 7 which is open to atmosphere at the end. In this manner the volume of milk held within the filler-needle. the duct 4 and the chamber 5 is accurately forwarded into the bottle 14. The volume of milk to be transferred to the bottle 14 in this manner can be modified, by replacing the duct 4 with a duct having a different internal volume.
In the event of a sample of milk from another milk container B being required in another bottle 14, after the initial sampling from a container B into a bottle 14, while the arrangement is still in the possition illustrated in Figure 1, the hose 7a is introduced into the other milk container B, and the full sample bottle 14 is replaced by another empty bottle 14. The filling operation is then repeated.
In the position represented in Figure 1, milk is also forwarded out of container B by way of duct 7 into chamber 6 as a result of the negative pressure in duct 1, and is then ejected through duct la.
Components 1, 3, 4, 5, 7a and 16 of the
arrangement through which the milk passes during a bottling operation, are flushed before the start of the following bottling
operation by means of the milk which is then bottled.
In a simpler design of the arrangement, in which open-topped bottles 14 are filled, the
duct 3 has no small tube 18 and the upper
end of the tube 7 is connected to a container, with a limited atmospheric overpressure. When the tube 3 in this type of
design is in the upper stroke position, it is filled with fluid from the container B, just as
represented in Figure 1. On reaching the
lower stroke position, the fluid passes
through the aperture 17 into the bottle 14.
