Abstract
The invention relates to a filling machine for the filling of an amount of edible ice into a container. The machine includes: space for containing said edible ice, filling unit, which contains a piston and a volume with at least one inlet and at least one outlet, where these create connections respectively to the space and container for the filling unit, and at least one valve. The at least one valve is an integrated part of the filling unit. The invention also relates to a method for the filling of an amount of edible ice into a container with a filling machine, and the use hereof.
Description
- The present invention relates to a filling machine for the filling of an amount of edible ice or an amount of a mixture which contains edible ice into a container, a method and use hereof.
- It is known to measure out a predetermined amount of edible ice in connection with transfer to a cup, ice boats, cone, freezing pockets or other similar containers.
- Existing techniques for the measuring out and distribution of edible ice contains e.g. a piston and a cylinder for driving the mass forwards, and subsequent valves for opening and closing in the transfer of the edible ice, where the opening time and frequency of the valve determine respectively the volume of the edible ice which is distributed and containers which can be filled.
- The independent functions make it complicated to get the individual components to work together, which makes this a troublesome and expensive process to establish. Moreover, several independent movable parts give rise to a greater uncertainty in the amount of edible ice which is measured and distributed in each case, which is undesirable when the demand is for many portions of sizes corresponding to one another. Also, a frequent cleaning of the components is necessary in order to ensure operational reliability, which is troublesome and delays the process.
- The invention creates a filling machine for edible ice which does not involve the problems for the above-mentioned known technique. The invention especially creates a filling machine with a simple and efficient construction. The invention also creates an operationally reliable filling machine which doses the edible ice quickly and precisely into cups, ice boats, cone, freezing pockets and other similar containers.
- Particularly, the invention comprises a filling machine where at least one valve is an integrated part of the filling unit.
- The present invention solves the above-mentioned problems with the known technique by providing a filling machine for edible ice which has integrated filling/pumping and valve mechanism in one unit. It is hereby possible to create a filling machine with a simple and efficient construction.
- With one embodiment, the piston is connected to drive means which can drive the piston to describe both linear and rotational movements, where the movements are simultaneous or one after the other, and each from a first position to a second position and vice versa. With the rotational movement of the piston, an advantageous possibility is achieved of being able to integrate a further functionality in the filling machine in addition to the pumping of the edible ice forwards to a container.
- With one embodiment, at least a part of the piston has a circular cross-section and at least one longitudinal narrowing-down in the shape of the piston such as a notch or a groove in relation to the circular cross-section. Hereby opens possibility of defining a passage between the volume and the inlet or outlet when the piston moves in the volume, and herewith creating an advantageous, integrated filling/pumping and valve mechanism.
- It shall be noted that the piston can be provided with other mechanisms than a narrowing-down for creating a valve mechanism in connection with the filling unit.
- With one embodiment, the narrowing-down (12) in the shape of the piston can be up to 90% of the cross-sectional area of the piston, such as up to half and e.g. between 20 and 40% of the cross-sectional area of the piston. Hereby advantageous relations are achieved between the following conditions: distance that the piston has to rotate, necessary precision of the rotational movement and complete closing of the inlet or outlet and production of the piston. In particular there is also achieved a sufficiently large passage so that plugs of edible ice are avoided.
- With one embodiment, the piston is provided with mixing means such as one or more projections placed on that part of the piston which is moved in said space. It is hereby possible to utilize the piston movement also for stirring the edible ice and for the stirring of other ingredients such as pieces of fruit, chocolate, nuts or other firm or fluid ingredients into the edible ice.
- With one embodiment, the openings for said at least one inlet and at least one outlet in said volume are placed at the same or substantially the same level.
- With one embodiment, the maximum amount of said volume corresponds to the amount of edible ice which is desired to be transferred to the container.
- With one embodiment, said narrowing-down has a length which at least corresponds to the distance from the bottom of said volume to the openings for said least one inlet and/or least one outlet.
- With one embodiment, said space, apart from said inlet, is e.g. a space closed with a cover where pressure can be applied to this closed space with pressure-creating means. There can hereby be created an overpressure in the space which presses edible ice or ice cream with higher viscosity more efficiently through the filling machine when this is allowed by the position of the piston.
- The invention also comprises a method for use in connection with the filling machine.
- With one execution of method, a rotation of a piston in the filling machine respectively opens and closes for a passage selected between inlet and outlet for edible ice to or from the filling machine's volume, while a linear movement of the piston presses edible ice for the volume through the passage for outlet.
- With a second execution of method, a narrowing-down in the piston establishes said passage for inlet or outlet after the rotation of the piston from a first position to a second position.
- With a further execution of method, a linear movement for pressing ice mass out of said volume is followed by a shorter linear movement in the opposite direction before a rotation of the piston. It is hereby possible to suck a possible remainder of edible ice out of the outlet so that this does not drip out of the filling machine.

FIG. 1 shows afilling machine 1 for measuring-out and transfer of predetermined amounts of edible ice tocontainers 2 which pass under anoutlet pipe 8 for the machine. In the figure, the containers are shown as cones which are fed successively under said outlet pipe by aconveyor belt 3. In addition to cones, the containers can also be other forms of containers for edible ice such as ice boats, ice cups or freezing pockets and paper or plastic packaging for edible ice. - A freezing pocket forms part of a mould unit for ice mass. The mould unit is hollow, where a coolant runs in the inside while a part of the surface consists of a number of moulds called freezing pockets. The freezing pockets are filled with edible ice, after which the coolant transfers cold through the material in which the freezing pockets are formed and herewith ensures a quick freezing-down of the edible ice. After the freezing-down, each edible ice items can be removed from their freezing pockets.
- The
filling machine 1 further consists of afunnel 5 secured on top of afilling unit 6, which at the bottom terminates with a bottom-plate 7 and the earlier-mentionedoutlet pipe 8. In the figure it is also shown that the end of apiston 4 protrudes out from thefunnel 5. -

In the figure it is also shown that the uppermost part of thepiston 4 is provided with an arm which works as anengagement 10 for a driving means for the piston, which will be explained in more detail in the following. - The
funnel 5 can be formed with a side length of at least 150 mm in the uppermost cross-section, such as 200 mm, with side lengths respectively at least 40 mm and at least 50 mm in the lowermost cross-section, such as 50 respectively 60 mm. - The
piston 4 mainly has a circular cross-section with a diameter of at least 20 mm and a length of at least 350 mm, such as 30 respectively 450 mm. -
FIGS. 3 and 4 show cross-sections of an embodiment of thefilling machine 1. It is shown that thepiston 4 is placed in the centre of the fillingmachine 1, and with a linear movement can be moved forwards and backwards in the longitudinal direction between two end positions. The two end positions for the piston are both placed in thefilling unit 6 which is also shown with avolume 13 which varies in size with the movement and position of the piston. The filling unit is provided with aninlet 11 which has theopening 9 in the bottom of the space of the funnel, and anoutlet 14 which has anopening 15 in the end of theoutlet pipe 8 over a container. - Moreover, the inlet and the outlet have
openings volume 13 through a narrowing-down 12 in a lowermost part of the side of the piston. - In the first end position shown in
FIG. 3 , thepiston 4 has been moved down to a position immediately above thebottom plate 7, so that thevolume 13 is as small as possible. At the same time, the narrowing-down 12 is positioned so that there is a passage from the space with the edible ice through theinlet 11 and the narrowing-down 12 to thevolume 13. The volume will thus be filled up with edible ice when thepiston 4 moves upwards. It is also shown in the figure that theopening 22 for theoutlet 14 is closed by the normal shape of the piston, and thus that there is no passage for edible ice from the volume to the outlet. - In the second end position of the
piston 4 as shown inFIG. 4 , the piston is rotated a half a turn after it has been raised linearly to the end position. Theopening 21 for the inlet is hereby now closed and the supply of edible ice is stopped. At the same time, a passage is created from thevolume 13 to the outlet through the narrowing-down 12 and thus further to the container when the piston is moved linearly downwards. - The end positions from
FIGS. 3 and 4 are naturally defined by thebottom plate 7 and by the placing of theopenings outlet piston 4 will not be raised over the openings, since there would otherwise be passage between inlet and outlet and thus no valve mechanism. - In

FIG. 4 it is also illustrated how driving means 16 a, 16 b are connected to thepiston 4, including to the arm 10 (as shown inFIG. 2 ), so that the piston can describe linear and rotational movements. The drive means can, among other things, be electric, pneumatic or hydraulic actuators, where the piston's movements e.g. are controlled with end stops. -
FIGS. 5 a to 5 b show cross-sections primarily of the filling unit and the piston in a first and a second embodiment. -
FIG. 5 a corresponds to an enlarged section of the filling unit shown inFIG. 3 , where inFIG. 5 a it is particularly shown that the piston is to be moved linearly upwards. - The inlet in the filling unit is shown as a closed passage down to an opening for inlet to the circular insides of the filling unit. The inlet can, e.g., be a vertical passage which is drilled down into the filling unit with said opening in the side.
-
FIG. 5 b shows an alternative embodiment forFIG. 5 a, where the inlet is shown as a slit which is open in towards the circular space in the filling unit. The inlet can, e.g., be a vertical milling in the filling unit's inner side in towards the piston. -
FIGS. 6 a and 6 b show cross-sections of the embodiment fromFIG. 5 a during different positions of thepiston 4. The figures also illustrate the course of the edible ice primarily in the filling unit during use of the filling machine. -
FIG. 6 a shows the linear movement of thepiston 4 upwards after a passage has been created through theinlet 11 and the narrowing-down 12 to thevolume 13 for theedible ice 17 in thespace 5. By the movement of the piston, there thus occurs a filling of thevolume 13 with theedible ice 17 from thespace 5, where the path of the edible ice is shown with thick arrows and black color in the volume. At the same time, it is shown that theopening 22 for theoutlet 14 is closed by thepiston 4, so that the edible ice can not come further from thevolume 13 during this upwards movement. -
FIG. 6 b shows the linear movement of thepiston 4 downwards after the movement inFIG. 6 a has reached its end the end position and the piston is rotated a half turn. By the rotation, passage was created from thevolume 13 through the narrowing-down 12 to theoutlet 14, and thus finally to the container. At the same time, theopening 21 for theinlet 11 has been closed, so that no further flow of edible ice from thespace 5 to thevolume 13 can take place during this downwards movement. By the movement downwards, thepiston 4 will little by little press the edible ice out of thevolume 13 through the narrowing-down 12 in the piston and theoutlet 14. - Since the
volume 13 becomes completely filled with edible ice by the upwards movement, the downwards movement of the piston will result in a transfer of a defined or measured amount of edible ice to the container under theoutlet pipe 8. -
FIG. 7 shows a cross-section of the funnel and thespace 5 containingedible ice 17 or a mixture of edible ice and additional firm or liquid ingredients such as pieces of fruit, chocolate, nuts or the like. The part of thepiston 4 in the space has fastened mixing means 18 a, 18 b for creating movement in the edible ice when the piston is in movement. - The figure shows the means as two displaced plates which are secured at right-angles to the piston, where especially the linear movement of the piston will create movement in the edible ice, and thus stir the edible ice and mix possible further ingredients into the edible ice before it continues down into the filling unit. This movement and stirring are illustrated in the figure with the two thick arrows.
- The mixing means can also consist of plates, blades, rods or the like attached to the
piston 4, where these are angled in relation to the horizontal plane. It is hereby also possible to take advantage of the rotating/linear movements of the piston to create movement in the edible ice. -
FIG. 8 shows thefunnel 5 provided with acover 19. Since the funnel can be tightly sealed, apart for theopening 9 for the inlet, it is possible with pressure-creatingmeans 20 to create an overpressure in the space. The edible ice can hereby be pressed through the inlet to the volume for the filling unit and sucked, due to the pressure difference, and thus not only be directed forwards by the force of gravity. The use of overpressure in the space will particularly be useful and expedient with edible ice of a more viscous kind. -
FIGS. 9 a to 9 c show an embodiment for thepiston 4 where particularly the narrowing-down 12 in the lowermost part is shown and defined in more detail. -
FIG. 9 a shows thepiston 4 seen from the side and in its full length. Also shown in the lowermost part of the piston is the narrowing-down 12, where this is defined with a length l and a thickness x in relation to the piston's cross-sectional diameter d. -
FIG. 9 b shows the cross-section of the piston at the cut-through line A-A and seen in the direction towards the uppermost end of the piston. -
FIG. 9 c shows the cross-section of the piston at the cut-through line A-A and seen in the direction towards the lowermost end of the piston. In this figure it is particularly clearly shown how a section is removed from the piston's circular cross-section. However, other forms of narrowing-down in the piston can be envisaged, including hollowing-out of the piston as exemplified inFIGS. 9 d to 9 f. - The thickness x will most often be between 20 and 40% of the piston's area in order to create a suitable passage for the edible ice, but in special embodiments can be right up to 80-90%. The diameter d of the piston can, e.g., be 30 mm at a length of 450 mm for the piston as a whole.
-
FIG. 9 d shows a further embodiment of the piston for use in the filling machine according to the invention, where the piston's narrowing-down 12 ends in a protruding bottom part with a hole in it. -
FIGS. 9 e and 9 f show other embodiments of the piston with narrowing-down seen in the direction towards the uppermost end of the piston. In the upper figure, the narrowing-down is shown with a relatively open hollowing-out, and while the lower figure shows a much closed hollowing-out. With the shown embodiments, the narrowing-down will take up a large part of the piston's circular cross-section. -
FIGS. 10 a and 10 b show an alternative embodiment of the fillingmachine 1, where the fillingunit 6 containing thepiston 4 is placed at right-angle to thefunnel 5 and inlet andoutlet - The fuctionality of this alternative embodiment is fundamentally the same as mentioned above in connection with FIGS. 3 to 6 b. For example,
FIG. 10 a shows the piston in an end position corresponding to that shown inFIG. 3 , whileFIG. 10 b shows the piston in an end position corresponding to that shown inFIG. 4 . - It shall be noted that the filling machine will most often be one among several filling machines placed side by side for simultaneous feeding of a number of containers which are conveyed successively by means of a conveyor belt or the like.
