The present invention relates to a bag filing machine, and in particular to a bag filling machine that may be used by an individual and controlled by hand.
Often it may be useful to fill a bag with material. The material may be sand, for example, to fill numerous sand bags as may be required to act against the ingress of water in a storm. Councils, emergency services, and other groups often will provide a pile of sand and empty bags for a person to fill. Sand is heavy and awkward to convey efficiently into a bag. If only a single bag were needed this may not be such a problem to shovel by hand, but for the use in a potential flood or storm a great many sand bags will be needed to be filled for use. Where the council may be assisting people to do so they may be filling hundreds of bags, which is hard physical work and will take a considerable length of time.
On a mine site or construction site, flowable materials such as gravel or sand may be moved in large volumes from one location to another, through use of large expensive equipment. Use of a loader or other large earthmoving machinery may be used, and in some cases tipper trucks to be filled with the material, before it is driven to another location and tipped out somewhere else for use. These large pieces of equipment are suitable on a mine site, but may be too costly for councils or smaller business or for emergency use. Further, in an emergency there needs to be ready access to the equipment, which may not be possible due to location.
Some large machinery may be known that includes a means to pick up flowable material, or may include a conveyor. However, large mining machines are very costly, and require large storage areas and large areas in which to work. There has long been a need for an improved method to fill sand bags and the like that automates the process, when compared to hand shovelling, in a compact and hand operated or personal operated way. Such a small machine may then be purchased by a council, or similar organisation, for regular use in day-to-day construction as well as being an essential part of their emergency deployment for use to rapidly fill sand bags for distribution. Due to the easy use by any person with minimal training, and the small profile, the machine can rapidly be deployed across a city in an emergency, located in many locations even if only a small area is available for the pile of sand to give access, and will dramatically improve the ability to quickly fill the sand bags. The invention provides a cost effective and realistic solution to a real problem.
The invention removes the need for the large earthmoving equipment, and, due to the inventive machines compact size, enables access to restricted spaces. The inventor has designed a small, personal machine that is easy to operate, so that a person could readily make use of it as need be, which compares to large mining machines that require lengthy training and certification before use may be made of the machine. The small personal machine means it can be used on a roadside or other suitable location for emergency sand bag deployment as often is the case when a storm or a cyclone is imminent or there is a high risk of flooding. The subject invention is quick and easy to use but is powered and automated so that the sand bags can be filled quickly and distributed where needed. A person can come along and quickly fill some bags and get back to their property at the earliest time to install the sand bags and hopefully for flood prevention. The compact design of the inventive apparatus allows for one or several to operate simultaneously at the same pile, approaching from all sides without clashing. In this way access to the pile is maximised, and bags and can be filled efficiently.
When compared to hand filling the sand bags the invention is a dramatic improvement. Use of large machinery or vehicles may be able to relieve the physical burden on a person when needing to fill numerous sand bags, but these large, costly and cumbersome machines and so are just not a practical solution to this problem. Further, public safety may be at risk in uncontrolled conditions such as an emergency where heavy machinery may be operated.
Through clever design and hand operated features, the inventor has provided a new way to fill sand bags much more easily than by hand, and in a machine that is suitable for domestic, council or other business use. The machine is easily moved by a single person, by hand and yet is a powerful machine that can run economically, efficiently and safely for many hours to fill the necessary bags, as required. The invention is likely to be very well received by the target market once known about, and will replace conventional hand filling methods.
The following describes a non-limiting example of the invention being used with reference to filling sand bags as a particularly useful application of the invention. However, the subject invention is a surprisingly clever and useful way to fill bags, or any receptacle, with any kind of flowable material. It is not intended that the invention be limited in anyway including to use for sand bags, other than is defined in the claims to invention. The invention may be useful in a wide range of application and industries.

The invention will now be described in connection with non-limiting preferred embodiments with reference to the accompanying drawings, in which:
Referring to
Manual control by person 2 has significant advantages over filling the bags by hand with a shovel, and large machines are often not suitable or may not be accessible where a person needs to fill the bags. The present invention instead provides a convenient machine that is able to be used at smaller sites, such as a council site. Further, for small businesses the invention will be most useful, where the cost of a large machine (which may only be used a few times a year) would otherwise be prohibitive to purchase and due to the need for registration and licenses to operate.
Bag filling machine 1, has handle 10, connected to frame 12 and it is through handle 10 that person 2 can easily manipulate and move the bag machine to effectively fill bags. Frame 12 with handle 10 form the strong basis for the machine to enable manipulation by a person by hand without the need for a vehicle engine or movement. The advantage to a shovel is that sand 3 can be shoveled even in small amounts into a bag and easily be manipulated in small areas. The cost of use of shovel is also low, but it is hard work and after a while the person will tire. If many bags are to be filled then using a shovel may quickly become a problem. Emergency situations may lead to people who are not used to physical activity needing to be involved in filling sand bags, which is hard physical work. Such intense bursts of physical activity can result in many injuries, such as back injuries, as well as general aches and pains. It would be most advantageous to lift some of the physical burden of filling sand bags in these circumstances. However, the subject invention shares some of the advantages of use of a shovel as the person can in a similar way push the machine into a thicker area of sand 3, so as to convey the sand towards a bag for filling but as the machine carries the material, the strength and energy needed by the person is much less. A motorised version is envisaged, which will still be controlled by hand by the person but additional power provided to assist the moving back and forth. In this form of the invention a motor would be included to help move the machine, with controls on the handle for ready access.
Steel tubing is used for frame 12, with shaping to the steel handle 10 for more comfortable use. Other strong materials could be used instead. Grips and covers can also be used to protect the hands of the user, for more convenient use. Or a shaped plastic or rubber handle can be included. Through pushing forward or back, and tipping the front of the machine into the sand the person can easily find a suitable amount of sand to fill onto the conveyor. A person can also use their feet on frame 12 to add additional strength and support movement in 360 degrees as needed while using the machine.
Conveyor 14 is mounted on frame 12 so that it is carried thereby and moved with the movement of handle 10. Conveyor 14 has conveyor belt 16 on conveyor support plate 17, the conveyor being driven by drive chain 18 powered by petrol engine 20 coupled with reduction gear box 21. As power is supplied the coupled reduction gear box drives the conveyor system moving the conveyor from the front towards the top. Pulley drum 22 supports front part 24 of conveyor belt 16, and pulley drum 26 supports top 28 of conveyor belt 16. It is from this top part that directed flowable material leaves the conveyor to fall under gravity into bag 30 mounted in bag mount 32. The flowable material can be small powder or grain such as sand but could also be gravel or pebbles or anything that can be conveyed to the top and fall into the bag. Different forms of the apparatus may be configured accordingly.
Conveyor belt 16 is a polyurethane belt with fins mounted in the usual manner to carry material directed from point a to point b. The fins pick up and move the flowable material with the movement of the conveyor in a smooth, and continuous action.
Bag mount 32 includes a bag support 34 (as shown ties for bag 30 to bag mount 32) and platform 36 and is a standard hessian bag. Different sizes of platform 36, frame and bag 30 can be used depending on the material. All of these flowable materials may be heavy or dense and so a small bag may be preferred. The bag may be a bag of canvas, or woven plastic suitably strong to hold the material of a typical form used to be loaded with sand or the like. Platform 36 is particularly useful to assist to accommodate different sized bags as it can be moved up and down accordingly. As the height of platform 36 is adjusted, this enables convenient filling of bags of different sizes.
Movement of machine 1 is achieved through use of rear wheels 38 and front wheels 40, which although not powered enable movement forward and back. Part of why the invention is so useful is that it uses the strength of a person but in such a way as it is not as tiring as using a shovel, and much more efficiently. Motorised versions would have similar advantages, as they are likewise manually manipulated but the extra motorisation would reduce fatigue.
Cover 42 covers the flowable material for the majority of the journey on the conveyor so that the maximum volume is able to be captured and bagged. Cover 42 is formed of a thick rubber material in the illustrated example. Material can be fed directly into feed box 44, including manually with a shovel to increase efficiency in which case flap 46 prevents loss of material. Material may also enter through on the conveyor when pushed into the material through flap 46 to be conveyed towards the top. The wide mouth to captures the most material, in this case sand, until it is directed within cover 42. Cover 42 is most useful so that spillage is minimised again improving efficiency. Also, to reduce spillage, side cover 48 can be seen. The covers are useful for additional safety to act against people putting their hands in or close to the conveyor. Likewise flap 46 keeps the moving material away from the user.
Push bar 50 aids pushing the apparatus into the pile of sand, using the strength of the legs of the person, to feed the conveyor. Push bar 50 can be seen located at the convenient lower location so that the person can apply or withdraw their foot as needed.
Useful features as shown include viewing window 52 of chute 54 so the person can see the material flowing in and the filling state of the bag. The bag is clipped or tied in place and the person can see what is happening through viewing window 52, to check that filling through the chute to the bag is happening and to stop as the bag becomes full.
In use, person 3 can push the front of the machine into sand 3 so the material starts to be moved up the conveyor disappearing over entrance 44, and flap 46 prevents the material falling out so it may be conveyed on and up towards the top. Use of adjustable wheels is envisaged so that height clearance can be adjusted to particular applications. This may be useful to adjust the fin distance of the conveyor and the ground, for example. Several of the apparatus may be used at the same time around a sand pile, due to the compact size and easy, hand operated use, a significant advantage over the prior art. It is anticipated for example, that four or more machines could be operating easily around a single sand pile for a significant improvement in efficiency. The invention is useful in small areas to minimise effort and reduce waste as the bags are easily filled.
Overall, the invention is a very useful invention that will replace manual bag filling and loading materials in smaller applications, where it is useful to have a small maneuverable machine to do so. The apparatus removes the potentially harmful bending and straining for manual shovelling and is replaced by an easy to use and efficient apparatus.

Steel tubing is used for frame 112, with shaping to the steel handle 110 for more comfortable use. Alternative materials may be used as would be understood. The handle may take any suitable form to facilitate the manual movement to use the machine. The handle is useful to give a full control to the operator.
Conveyor 114 is mounted on frame 112 so that it is carried thereby and moved with the movement of handle 10. Conveyor 114 has conveyor belt 116, conveyor support plate 117, and the conveyor is driven by drive chain 118 powered by petrol engine 120 and connected reduction gear box 121. Pulley drum front 122 supports front part 124 of conveyor belt 116, and pulley drum top 126 supports top 128 of conveyor 116. In the same way, material is caused to enter front of conveyor and be carried up and over the top to fall under gravity to the bag.
Again, bag mount 132 includes a bag support 134 (as shown ties for bag 130 to bag mount 132) and platform 136. Different sizes of platform 136, frame and bag 130 can be used depending on the material. All of these flowable materials may be heavy or dense and so a small bag may be preferred. The bag is shown as a hessian bag. Platform 136 is particularly useful to assist to accommodate different sized bags as it can be moved up and down accordingly.
Movement of machine 101 is achieved through use of rear wheels 38 and front wheels 140, which although not powered enable movement forward and back. Part of why the invention is so useful is that it uses the strength of a person but in such a way as it is not as tiring as using a shovel, and much more efficiently.
Cover 142, feed box 144, flap 146 are all as described for the first embodiment enabling the flowable material to enter and travel the conveyor. Again, the progress of the filling of the bag can be checked the viewing window 152 of chute 154.
The invention is clearly most advantageous and is used in the same way as described for the first embodiment to easily and efficiently fill as many sand bags as are needed, such as in preparation for a storm, cyclone or flood. The illustrated apparatus provides a faster and more efficient way to fill sand bags or the like.

Steel tubing is used for frame 212, with shaping to the steel handle 210 for more comfortable use. The handle may take any suitable form to facilitate the manual movement to use the machine. Conveyor 214 as shown is similar to as described elsewhere and is mounted on frame 212 so that it is carried thereby and moved with the movement of handle 210. Conveyor 214 has conveyor belt 216, conveyor support plate 217 all driven by drive chain 218 powered by petrol engine 220 and with reduction gearbox 221. Pulley drum 222 supports front part 224 of conveyor belt 216, and pulley drum top 226 supports top 228 of conveyor 216. In the same way, material is caused to enter front of conveyor and be carried up and over the top to fall under gravity to the bag.
Again, bag mount 232 includes a bag support 234 (as shown ties for bag 230 to bag mount 232) and platform 236. Different sizes of platform 236, frame and bag 230 can be used depending on the material. All of these flowable materials may be heavy or dense and so a small bag may be preferred. The bag may be a standard material bag, of canvas, or woven plastic suitably strong to hold the material. Platform 236 is particularly useful to assist to accommodate different sized bags as it can be moved up and down accordingly.
Movement of machine 201 is achieved through use of rear wheels 38 and front wheels 240 in tracks 237. Track 237 allow easy movement over any ground surface include in mud, rough ground, or where there is not clear path. Away from town, such as on a farm, or in a time of disaster where paths are not clear the use of tracks 237 will be most useful.
Cover 242, feed box 244, flap 246 all work as described for the other embodiments to capture and contain the flowable material so that it is conveyed to the top and over to the bag. Viewing window 252 of chute 254 are useful inclusions to monitor the bag filling as it happens.
Use of the tracks instead of just wheels in the other forms of the invention will allow use in different environments, such as on a farm or off road where wheels may be not be able to be used.

Bag filling machine 301, has handle 310, connected to frame 312 and it is through handle 310 that the person can easily manipulate and move the bag machine to effectively fill bags. Pushing down can allow full manipulation as described elsewhere. Frame 312 with handle 310 form the strong support basis for the machine to enable manipulation by a person by hand without the need for a vehicle engine or movement. Other forms and arrangements may be used instead.
Steel tubing is used for frame 312, with shaping to the steel handle 310 for more comfortable use. A person push and rotate frame 312 to add additional strength and support movement in 360 degrees as needed while using the machine.
Conveyor 314 is mounted on frame 312 so that it is carried thereby and moved with the movement of handle 310. Conveyor 314 has conveyor belt 316 on conveyor support plate (not labelled), the conveyor being driven by drive chain 318 powered by petrol engine 320 coupled with reduction gear box (not labelled). As power is supplied the coupled reduction gear box drives the conveyor system moving the conveyor from the front towards the top. Pulley drum 322 supports front part 324 of conveyor belt 316, and pulley drum 326 supports top 328 of conveyor belt 316. It is from this top part that directed flowable material leaves the conveyor to fall under gravity into bag 330 mounted in bag mount 332. Other forms of power and control to the conveyor could be used in alternative forms of the invention.
Conveyor belt 316 is a polyurethane belt, and in this form of the invention instead of fins, includes pockets (not labelled) cast into conveyor belt 316 and so carried therewith on operation of the machine. The pockets are sized to readily capture material, carry the material and not to loose it on the way up. Having a smaller pocket of 30 to 50 millimetres assists to rapidly and efficiently carry the material from the front of the machine up to be bagged. Smaller or larger pockets can be used instead. A conventional straight conveyor could not capture the material, but through use of these inventive pockets small incremental portions of the flowable material are taken from the pile and carried up and directed away for bagging.
Bag mount 332 includes a bag support 334 (as shown ties for bag 330 to bag mount 332) and platform 336 and is a standard hessian bag. Different sizes of platform 336, frame and bag 330 can be used depending on the material. All of these flowable materials may be heavy or dense and so a small bag may be preferred. The bag may be a bag of canvas, or woven plastic suitably strong to hold the material of a typical form used to be loaded with sand or the like. Platform 336 is particularly useful to assist to accommodate different sized bags as it can be moved up and down accordingly. As the height of platform 336 is adjusted, this enables convenient filling of bags of different sizes.
Movement of machine 1 is achieved through use of rear wheels 338 and front wheels at location 340, which although not powered enable movement forward and back. Part of why the invention is so useful is that it uses the strength of a person but in such a way as it is not as tiring as using a shovel, and much more efficiently. Motorised versions would have similar advantages, as they are likewise manually manipulated but the extra motorisation would reduce fatigue.
Cover 342 covers the flowable material for the majority of the journey on the conveyor so that the maximum volume is able to be captured and bagged. Cover 342 is formed of a thick rubber material in the illustrated example. Material can be fed directly into feed box 344, including manually with a shovel to increase efficiency in which case flap 346 prevents loss of material. Material may also enter through on the conveyor when pushed into the material through flap (not labelled) to be conveyed towards the top. The wide mouth to captures the most material, in this case sand, until it is directed within cover 342.
The use of the capturing pockets in the conveyor is advantageous to maximise the capture and retaining of the flowable material to quickly move material from the pile on the ground to the bag.
In all forms of the invention the person can easily turn on the motor and start the movement of the conveyor in the usual way. The covered section prevents accidental loss of the material making the system efficient. Then the person can use their own strength to push the front of the conveyor into the material which can then start to be conveyed up to the top. As the material reaches the top if falls into the bag and once full the bag removed and sealed. Multiple bags can be quickly and easily filled in this way.
The inventor has through careful development provided an invention that surprisingly addresses a problem that has not been solved until now.
The machine may be manufactured industrially and supplied either direct to government or other organisations, or to retailers or wholesalers.
It will be apparent to a person skilled in the art that changes may be made to the embodiment disclosed herein without departing from the spirit and scope of the invention in its various aspects.
