- the supply means can be formed by a feed belt.
- the supply means comprise a crate tipper arranged above the buffer bin. It is hereby possible to also use the device for transferring product.
- a sack can be arranged in the buffer bin, the end of which sack is situated in the outflow opening of the buffer bin.
- the trunk-like outer end of the sack then serves as the actual outflow opening of the buffer bin.
- the pivoting flap(s) serve(s) to regulate the size of the outflow opening, or a piece of string can be tied round the trunk.
- a container can be filled very quickly and without disruption, and without damaging product herein.
- the invention has for its object to provide an improved method for filling a container for storage and/or transport with product as according to the type described in the introduction.
- a method for filling a container for storage and/or transport with product, in particular crops, for instance potatoes comprising the steps of:
- the preferably empty container is herein positioned at the filling location such that a closable outflow opening of the buffer bin is placed close to the bottom of the empty container. It is hereby possible to have the product drop into the container from a minimal drop height without herein damaging the product.
- the bottom of the container is moved an increasingly larger distance from the outflow opening of the buffer bin. In this manner the content of the buffer bin is transferred to the container quickly and without damaging the product.
- the content thereof is preferably weighed and, when a preset weight is reached, the supply of product is interrupted in order to then empty the content of the buffer bin into the container in one operation by opening the closable outflow opening, wherein the product falls into the container from a minimal drop height.
- a crate or a big-bag can be chosen as container for storage and/or transport.
- Step a) can further be carried out using a feed belt or a crate tipper, which is placed above the buffer bin for filling purposes.
- Product can be transferred in simple manner with a crate tipper.
- a sack can be arranged in the buffer bin for filling purposes, the end of which sack is situated in the outflow opening of the buffer bin.

Description
- The present invention relates to a device and method for filling a container for storage and/or transport with product, in particular crops, for instance potatoes. The device comprises supply means and a filling location where an empty container can be positioned for filling, wherein the supply means carry the products to the container. The method comprises the steps of a) supplying product in the direction of the container, and b) dropping the product into the container from a minimal drop height.
- Many crates are filled every year with agricultural products such as potatoes, onions, chicory root, carrots, flower bulbs and so on. During filling of the crate it is important to place the product in the crate without damage. In addition, the crate must be properly filled. If a crate is too full, the product is then damaged when a subsequent crate is placed thereon, and there is a chance of spillage. If a crate is not full enough, this signifies a less than optimal utilization of the available space.
- Different devices and methods for filling crates with for instance potatoes are known from the prior art. A first prior art crate filler is provided with a horizontal adjustable feed belt, wherein a filling location for a crate is situated at each end surface thereof. The end surfaces of the horizontal feed belt can be tilted into the crate, so that the reversing end of the belt reaches close to the bottom of the crate. The crates are filled in turn with potatoes. During filling the downward tilted end of the feed belt is returned slowly to the horizontal position and the horizontal feed belt is displaced in the direction of the empty crate placed opposite in order to lower the other end into the crate.
- In a second crate filler known from the prior art, vertically adjustable filling belts with finger-like carrier members are provided on the ends of the horizontal adjustable feed belt, which carrier members are lowered into the crate and drop the product layer by layer into the crate from a minimal drop height.
- Although these known crate fillers place the product in the crate without damage, they have the following drawbacks. Firstly, the known crate fillers take up a lot of space due to the configuration of two filling locations the size of a crate and the feed belt with drive construction situated therebetween. In addition, these crate fillers are subject to malfunction and wear as a result of the moving construction components. Although it appears to be a dual system, doubling of the capacity relative to a single crate filler is not achieved since the second crate is only filled once the first crate has been completely filled. The filled crate is collected by a fork-lift truck driver who, as a result of protruding machine components, must be alert when removing a full crate and placing an empty crate. A final drawback is that the driver has different routes to cover, which can cause a delay in the filling process.
- Known from the Netherlands patent application 9201646 is a filling device wherein materials are carried on a conveyor belt into a buffer bin or filling holder, which is arranged between the conveyor belt and a crate in which the products must be received. The filling holder has a bottom formed by pivoting flaps. The side of the filling holder directed toward the conveyor belt is closed by a screening wall. The filling holder is moved downward in each case during filling thereof. The filling holder is moved into a crate situated thereunder. During pouring the filling holder is moved upward. The known construction is however rather complicated.
- The object of the present invention is to provide a device wherein the above stated drawbacks are obviated.
- According to a first aspect of the invention, there is provided for this purpose a device for filling a container for storage and/or transport with product, in particular crops, for instance potatoes, comprising:
- supply means for supplying the product to a filling location where an empty container can be positioned for filling purposes;
- a frame;
- a stationary buffer bin, positioned between the supply means and the filling location and arranged on the frame, for receiving a determined quantity of product before the container is filled;
- The device according to the invention has a buffer bin which is arranged between the supply means and the filling location and which has a closable outflow opening for receiving a determined quantity of product before the container is filled. Because a buffer bin is used, a more compact device is obtained compared to the prior art, while this is not to the detriment of the filling capacity of the device.
- In a preferred embodiment lifting means are provided at the filling location for lifting the bottom of the container to a position close to the outflow opening and for lowering the bottom during filling of the container. The lifting means can for instance be formed by a fork-lift truck or by a lifting mechanism designed especially for the device. Because the buffer bin remains stationary and the container is displaced up and downward, it is possible to suffice with a relatively simple construction. The device can moreover be modified quickly and easily for application of different types (dimensions, form, material, etc.) of containers.
- The buffer bin is preferably provided with at least one pivoting flap for closing the outflow opening. Opening and closing of the pivoting flap can take place automatically or on command using suitable means.
- In an advantageous embodiment the outflow opening is arranged in or close to the bottom of the buffer bin. The filling location is in that case situated under the buffer bin, whereby a further space saving is achieved compared to the prior art.
- The container for storage and/or transport is preferably a crate or a big-bag.
- In order to enable proper filling of a crate, there is preferably arranged a transverse partition dividing the outflow opening in two. Filled crates are often stacked on top of each other. On the underside the crates have a supporting beam in the centre which can damage the product when a crate is overfilled. Because the outflow opening is now divided in two, the product from the buffer bin is placed in the crate such that two peaks of product are created at the top of the crate, with space between the peaks for the cross beam on the underside of the crate for stacking thereon.
- In order to collect the dirt still present in the product and not allow the outflow opening to become blocked, a blocking member is arranged in the buffer bin at a distance from the transverse partition.
- The device is further provided with weighing means for weighing the content of the buffer bin. At a command from the weighing means the pivoting flap or flaps is or are opened. It is hereby possible to fill the containers precisely with a preset weight so that it is known how many kilograms of product in total are stored or delivered.
- One or more fall breakers are further arranged in the buffer bin in order to also transfer the product from the supply means to the buffer bin without damage.
- The supply means can be formed by a feed belt. According to another embodiment, the supply means comprise a crate tipper arranged above the buffer bin. It is hereby possible to also use the device for transferring product.
- Finally, a sack can be arranged in the buffer bin, the end of which sack is situated in the outflow opening of the buffer bin. The trunk-like outer end of the sack then serves as the actual outflow opening of the buffer bin. The pivoting flap(s) serve(s) to regulate the size of the outflow opening, or a piece of string can be tied round the trunk.
- With the device according to the invention a container can be filled very quickly and without disruption, and without damaging product herein.
- In addition, the invention has for its object to provide an improved method for filling a container for storage and/or transport with product as according to the type described in the introduction. According to the invention there is provided for this purpose a method for filling a container for storage and/or transport with product, in particular crops, for instance potatoes, comprising the steps of:
- a) supplying product in the direction of the container, and
- b) dropping the product into the container from a minimal drop height, wherein during step a) and before step b) the following steps take place of:
- c) arranging product in a buffer bin from above until the buffer bin is filled with a determined quantity of product,
- d) subsequently emptying the content of the buffer bin in one operation into the container, wherein the bottom of the container is moved an increasingly greater distance from the outflow opening of the buffer bin during step d).
-
- The preferably empty container is herein positioned at the filling location such that a closable outflow opening of the buffer bin is placed close to the bottom of the empty container. It is hereby possible to have the product drop into the container from a minimal drop height without herein damaging the product.
- During emptying of the buffer bin into the container the bottom of the container is moved an increasingly larger distance from the outflow opening of the buffer bin. In this manner the content of the buffer bin is transferred to the container quickly and without damaging the product.
- During filling of the buffer bin the content thereof is preferably weighed and, when a preset weight is reached, the supply of product is interrupted in order to then empty the content of the buffer bin into the container in one operation by opening the closable outflow opening, wherein the product falls into the container from a minimal drop height.
- A crate or a big-bag can be chosen as container for storage and/or transport.
- Step a) can further be carried out using a feed belt or a crate tipper, which is placed above the buffer bin for filling purposes. Product can be transferred in simple manner with a crate tipper.
- Finally, a sack can be arranged in the buffer bin for filling purposes, the end of which sack is situated in the outflow opening of the buffer bin. The trunk-like end of the sack then serves as the actual outflow opening of the buffer bin. The size of the outflow opening can be readily modified to the desired outflow of product.
- The invention will be elucidated with reference to the annexed drawings. In the drawings:

- Figures 4A-4G show a schematic representation of the filling of a crate according to the method of the invention,
- Figures 5A and 5B show a schematic representation of the removal of dirt from an outflow opening of a buffer bin,
- Figure 6 is a perspective view of a device according to the invention provided with a crate tipper,
- Figure 7 is a partly cut-away perspective detail view of the buffer bin,
- Figure 8 shows a device according to the present invention deployed as big-bag filler, and
- Figure 9 shows a schematic representation of another application of the device according to the present invention.
-
- Figure 1 shows a perspective view of a device for filling
crates 1 with forinstance potatoes 2. The device comprises afeed belt 3 which debouches on the top side of abuffer bin 4.Buffer bin 4 is mounted on aframe 5 such that space is created underbuffer bin 4 for positioning anempty crate 1 that has to be filled. The positioning of anempty crate 1 and discharge of the filledcrate 1 take place by means of a fork-lift truck 6. Sensors 7 andconnectors 8 are mounted onframe 5 for the purpose, among others, of controllingfeed belt 3. - The partly cut-away detail view of figure 2 shows that fall
breakers 9 are provided inbuffer bin 4. Thesefall breakers 9 break the fall of the potatoes as they are transferred fromfeed belt 3 to bufferbin 4. On the underside thebuffer bin 4 is provided with an outflow opening which can be closed by means of two pivoting flaps 10. Each pivotingflap 10 pivots about apivot shaft 11, which is connected via apivot arm 12 to acylinder 13. On the underside ofbuffer bin 4 is further arranged atransverse partition 14 dividing the outflow opening in two.Transverse partition 14 is a reverse V-shaped beam to which the free ends of pivotingflaps 10 connect for the purpose of closing the outflow opening ofbuffer bin 4. - With reference to figure 3 it can be clearly seen that above and at a distance from transverse partition 14 a blocking member 15 is arranged in
buffer bin 4. This blocking member 15 prevents foliage and the like present betweenpotatoes 2 from remaining on the upper side oftransverse partition 14 and impeding closing of pivoting flaps 10. Blocking member 15 can optionally be rotated through one turn when flaps 10 open, so that the foliage falls intocrate 1 along withpotatoes 2. In figure 3 it is further just possible to see astop sensor 16 which is mounted onframe 5 at the position ofpivot shaft 11 offlap 10. A similar stop sensor (not shown in the drawing) is situated on the other side ofbuffer bin 4. Stopsensors 16 detect when anempty crate 1 is in position for receivingpotatoes 2 frombuffer bin 4. -
Buffer bin 4 is arranged on either side on weighingbeams 17 in order to weigh the content ofbuffer bin 4. The signals from weighingbeams 17 are converted incontrol unit 18 into control signals forfeed belt 3 andcylinders 13. - The method according to the invention will be elucidated hereinbelow with reference to figures 4A-4G.
- Before the supply of
potatoes 2 can be started, weighingbeams 17 are set to 0 kg, whereafter filling ofbuffer bin 4 can begin.Feed belt 3supplies potatoes 2 abovebuffer bin 4.Potatoes 2 enter thebuffer bin 4 viafall breakers 9 without being damaged (figure 4A). A fork-lift truck driver drives beneathbuffer bin 4 with anempty crate 1 and liftscrate 1 upward so thatbuffer bin 4 lowers intocrate 1 and the outflow opening ofbuffer bin 4 is situated close to the bottom of crate 1 (figures 4A and 4B). Whencrate 1 has been moved far enough upward, it comes into contact withstop sensors 16. The sensors generate a signal to controlunit 18 as an indication that anempty crate 1 lies ready to be filled. As soon as the content ofbuffer bin 4 reaches the preset weight, feedbelt 3 is immediately stopped and the two pivotingflaps 10 are immediately opened using cylinders 13 (figure 4C). At the moment the two pivotingflaps 10 open, thepotatoes 2 fall intocrate 1, wherein the drop height is minimal so that no damage occurs (figure 4D). The fork-lift truck driver quickly lowerscrate 1 so thatcrate 1 is rapidly filled with potatoes 2 (figures 4D and 4E). As soon ascrate 1 is at the bottom, the fork-lift truck driver can drive away therewith to the storage area. Whencrate 1 is at the bottom, contact is made with sensors 7 which generate a signal to controlunit 18, which in turn gives the command to close the two pivotingflaps 10 and to drive feed belt 3 (figure 4F). While the fork-lift truck driver places thefull crate 1 in storage and returns with anempty crate 1,buffer bin 4 is filled once again with potatoes 2 (figure 4G) until the preset weight is reached, so that the content ofbuffer bin 4 can be discharged rapidly intocrate 1. - Due to the
transverse partition 14 two peaks of product are created at the top ofcrate 1 during filling (see figure 4E), and since the crates have on the underside a cross beam in the centre a crate can now be placed on top of the filled crate without therein damaging product. - Figures 5A and 5B show how flaps 10 close. Owing to the closing position of
flaps 10 not being the same (figure 5B), dirt such as foliage which has come to lie ontransverse partition 14 is easily removed. When no blocking member 15 (figure 3) is provided in the buffer bin, the foliage and the like falls directly ontotransverse partition 14. By now closing theflaps 10 to the dissimilar closing position shown in figure 5C after emptying of the buffer bin, and from a position of open flaps 10 (figure 5A), the foliage will automatically drop downward when flaps 10 are opened again. - Figure 6 shows a device according to the invention with
crate tipper 19. The crate tipper is a per se known device for tipping and emptying crates. Thecrate tipper 19 comprises a basic frame 20 and atilting frame 21 tiltable relative to basic frame 20. Amotor 22 is provided for tilting the tiltingframe 21. Tiltingframe 21 comprises a fixed bottom 23 and a partlypivotable cover 24. Using a fork-lift truck a filled crate can be placed via the front side intocrate tipper 19, between bottom 23 andcover 24. Usingmotor 22 the tiltingframe 21 is then tilted rearward relative to basic frame 20. The crate is rotated through more than 90° so that the top side of the crate is then directed downward in the direction ofbuffer bin 4, and the partly pivotingcover 24 opens. The content of the crate is hereby gradually tipped over intobuffer bin 4. Once the desired quantity of product has been tipped intobuffer bin 4, tiltingframe 22 is returned to its starting position. - In the device of figure 6 two
flaps 27 are further mounted on the underside ofbuffer bin 4.Flaps 27 are attached tochains 25 which are fixed to theextended pivot arms 12. When flaps 10 are opened, flaps 27 will be lowered and descend into the container to ensure that no product falls out of the container during the downward movement of the container. - In the device of figure 6 is also shown that
frame 5 is height-adjustable using a pin/hole connection 17 arranged in each leg. - The configuration shown in figure 6 can be used for tipping product from a crate into a crate of different or the same type. In the case of onion sets, potatoes, grass seed and such products, which are placed in front of a drying wall in wet conditions, it is sometimes suitable to transfer the product. The drying time is sometimes hereby shortened by as much as 60 to 70%.
- Figure 7 shows a partly cut-away perspective detail view of
buffer bin 4. Corresponding components are designated with the same reference numerals. - Figure 8 shows a device according to the present invention applied as big-bag filler. The big-bag filler is substantially identical to the crate filler, with the difference that
transverse partition 14 and blocking member 15 have been omitted, thatparts 26 of the outflow opening are folded away, and that asack 30 is optionally arranged inbuffer bin 4, theend 31 of which sack is situated in the outflow opening ofbuffer bin 4. Theend 31 ofsack 30 is held closed by the two pivotingflaps 10 and extends downward beyond theseflaps 10. A trunk-like outflow opening is hereby obtained, the diameter of which, and therefore the quantity of product dispended thereby per unit of time, can be regulated by means offlaps 10. An empty big-bag 32 is suspended from theforks 33 of the fork-lift truck. Alifting platform 34 places the bottom of the big-bag a short distance from the outflow opening in order to reduce the drop height of the products during filling of the big-bag. During filling of the big-bag the lifting platform will move downward under the increasing weight. It is also possible to fill big-bags without making use ofsack 30. - Big-bags are used increasingly more often to package agricultural products, and in particular planting material. A drawback of big-bags is that they take up a lot of floor space, since the filled big-bags can hardly be stacked. If the potatoes will not be removed immediately after sorting, it is then possible to store the potatoes in the correct quantities, preferably depending on the weight, in crates which can be stacked. When the potatoes are collected, the crates can be tipped into big-bags quickly and easily for transport using the device of figure 8 extended with the
crate tipper 19 of figure 6. - Figure 9 shows a variant of the configuration shown in figure 8. The trunk-
like outflow opening 31 is used here as dispensing means for dosed delivery of product. Instead offlaps 10, a piece of string tied round the trunk-like end 31 can also serve as regulating means for regulating the size of the outflow opening. Under the outflow opening can be placed aconveyor belt 35 with speed control which discharges the products to a truck, sorting machine, clod separator, cutting machine or the like. The device then in fact functions as dispensing bunker for the following truck or machine. The device of figure 9 can also be combined with a crate tipper 19 (figure 6). - Using the device and method according to the invention it is possible to know precisely how many kilograms of product are in storage. This can be particularly important for the buyer of the product. Everything can be planned better in advance so that no surpluses or shortages result. In addition, it is possible to deliver a batch of product to the exact kilogram, as the buyer desires.
- The speed of the device is high, sixty tons per hour being readily feasible, and the device is also only 2 to 2.5 metres wide. Compared to traditional crate fillers, the device according to the present invention has much fewer rotating structural parts, whereby fewer malfunctions occur as well as less maintenance being necessary.
- The invention is not limited to the embodiment shown in the accompanying drawings.
