Definitions
- the present invention relates to a filling system for filling substance into containers.
- the invention further relates to a method of operating such filling system.
- Filling of containers with one or more substances is a common task of packaging substance e.g. for transportation or storage purposes.
- gas such as liquid petroleum gas - also known as LPG
- filling turntables and carrousels are often used.
- Containers are conveyed and transferred to the turntable or carrousel, where they are received by filling units and each continuously weighed on an electronic scale.
- the scales are connected to a control system, which controls filling of the containers in response to signals from the scales, the signals being proportional to the amount of substance filled into the containers.
- This type of filling is used for filling several hundreds or even thousands of containers per hour with LPG.
- the turntables or carrousels are equipped with multiple, normally at least a dozen, filling units, each having a scale included, for filling many containers at a time and it is performed in a cycle where containers are received in a first position, filled during rotation of the turntables or carrousels to bring the filled containers to a second position where they are unloaded.
- this known method of filling containers functions very well, it does, however, require a large number of scales and corresponding control equipment.
- a system of this type is e.g. known from WO 9939130 A2.
- One object of the invention is to provide a filling system with a reduced number of scales included as well as a corresponding method of operating such system. Another object is to provide a filling system having at least a capacity which is equal to the known type of filling systems as well as a method of operating the system to obtain such capacity.
- a first aspect of the invention involves a filling system comprising:
- a substance distribution system comprising filling means arranged relative to the transport units for filling substance into at least one container while said at least one container is transported by a transport unit,
- At least one electronic scale incorporated in each of at least two separate and substantially horizontal sections of the track, where said sections are adapted to provide individual weighing sections distributed in the track, said weighing sections being arranged to weigh the transport units individually, including any present containers and substance, while the transport units are passing the weighing sections when being moved by the driving means, and where operation of the filling system includes operations in relation to weighing information obtained from the weighing sections.
- the filling system may include only two scales, i.e. one for each of the at least two weighing sections, although there may be any number of transport units. This is significantly less than the known systems, which include a scale for each transport unit and thereby normally at least twelve scales for a system having twelve transport units.
- the filling system may include any number of transport units, such as from 6 to 36, such as 6, 12, 24, or 36, or any other number in between the mentioned numbers or a higher number, and be operated using two scales only. Additional scales may be used for increasing precision, performing further operations, checking weighing etc.
- the scales are incorporated in separate weighing sections of the track, said sections being placed with a distance in the direction of the track.
- the weighing sections are arranged to weigh the transport units individually, including any present containers and substance, while the transport units are passing the weighing sections.
- Information with regard to the amount of filled substance in at least two instances in the filling sequence, may hereby be obtained.
- This weighing information forms a basis for operating the filling system, such as enabling calculation of a total filling time, which is necessary for appropriately filling the containers, as well as operating the filling means accordingly.
- the features of the filling system may be implemented in a carrousel or turntable system whereby the filling capacity, i.e.
- the track may be circular and the filling system implemented as a carrousel, or it may be oval or having a polygon-like shape, where the transport units are transported in a loop, and where filling may take place during most of the loop. Or the part of the track where filling takes place may have any shape.
- This may include a linear part where the containers are transported in one linear direction only.
- the track may be elevated e.g. to an overhead position where the transport units are hanging downwards from the track.
- the transport units and the filling means may be integrated. This may include an embodiment where the containers are engaged only at their filling opening, e.g. a bottleneck, by the transport units/fillings means and are transported also in that way at least during the filling operation.
- a preferred embodiment of the filling system involves placing at least two weighing sections in positions downstream of a position of the track where filling is to be started and upstream of a position where filling is to be completed.
- the term "downstream” indicates a position positioned in the direction in which the transport units are moved and the term “upstream” indicates a position positioned in a direction which is opposite to the direction in which the transport units are moved.
- a first weighing section placed after a position of the track where filling is to be started may provide a first indication of an amount filled into the container, which amount may be used to calculate a filling rate, i.e. the amount of substance filled per time unit. The filling rate may then be used to calculate the filling time for reaching a first predetermined filling level.
- a second weighing section placed before a position where filling is to be completed may provide a second indication of an amount filled into the container, e.g. to check whether the first predetermined level has been obtained, and/or to calculate the filling rate again based on a longer time period than the first calculated filling rate.
- the second indication of filled amount may also be used to calculate a remaining amount still to be filled into the container as well as a remaining filling time for a top-up filling operation.
- Another preferred embodiment of the system includes that at least one weighing section is placed in a position downstream of a position of the track where filled containers are unloaded from the transport units and a position upstream of a position where containers to be filled are received by the transport units.
- a weighing section may be used to obtain a tare weight of the transport unit. Any spilled substance or other generally undesired matter randomly present on the transport unit would otherwise compromise the precision of the filling operation, e.g. lead to filling less substance into the container than intended.
- a further preferred embodiment of the system includes that at least one weighing section is placed in a position downstream of a position of the track where containers to be filled are received by the transport units and upstream of a position where filling is to be started. Such weighing section may be used to obtain a tare weight of the transport unit including a container.
- a yet further preferred embodiment of the filling system includes that at least one weighing section is placed in a position downstream of a position of the track where filling is to be completed and upstream of a position where filled containers are unloaded from the transport units.
- Such weighing section may be used to check the weight of the transport unit, the container and the substance filled into the container. When the tare weight of the transport unit and the container is known, this may provide information regarding the amount of substance which has actually been filled into the container, such that e.g. the filled amount may be checked against a desired amount, an acceptance interval, a maximum amount, a minimum amount, etc.
- Another preferred embodiment of the filling system includes that at least one wheel or roller is arranged between each transport unit and the track to provide movable support for the transport unit.
- at least one sliding shoe may be arranged in a similar manner. This provides a suitable direct contact between the transport unit via the wheel, roller or sliding shoe to the track, and hence also to the weighing sections incorporated in the track.
- One wheel is preferred, because it provides opportunity to weigh the transport unit etc. over the entire length of the weighing section and hence provide maximum time for performing the weighing operation. This is advantageous since the length of the weighing section must be less than the width of a transport unit, here the centre to centre distance between the wheels of two adjacent transport units, since only one transport unit may be present on the weighing section at a time to perform an individual weighing. This highly increases the capacity of the filling system, since the transport units may be moved fast and the weighing operations still be made with sufficient precision.
- a further preferred embodiment of the filling system includes that the track is made in sections made from rails or rail-like metal profiles. Rails and metal profiles provide a solid, durable structure at a reasonable cost.
- An additional preferred embodiment of the filling system includes each transport unit having at least two supporting arms, said supporting arms being hinged to the transport units in one end and hinged to a central section of the driving means in an opposite end, where each transport unit, a set of two arms and said central section are arranged to structurally form a parallelogram which supports said transport unit.
- the two supporting arms hinged to the transport unit and arranged to form a parallelogram in combination with the other components provide the function that when the container carrying part of the transport unit is horizontal when the transport unit is installed, then it is kept horizontal at all times despite any minor variations in the track, such as a small deviation from a common horizontal plane of the track. If the container carrying part of the transport unit is not horizontal, load from the container will be introduced in the supporting arms, whereby the full load is not transferred to the weighing sections. This is avoided by the parallelogram and the precision in the weighing is maintained.
- the filling system according to the invention may be used for any substance, e.g. a powder, a gas, a fluid or a liquid, or a combination of such substances, or it could be granules, or a plurality of pieces of different size, even larger pieces e.g. vegetables such as carrots, potatoes, etc.
- a preferred use of the system is for filling containers with a liquefied gas, in particular a liquid petroleum gas (LPG).
- LPG liquid petroleum gas
- Another aspect of the invention relates to a method of operating a filling system for filling substance into containers, where operation of the filling system for filling a container includes steps of:
- the filling system may be operated on the basis of input from only two scales.
- the risk that too much or too little substance is filled into the container is reduced, i.e. a high degree of precision is obtained in the filling although only two scales are used.
- Filling may be continued or discontinued while weighing is performed, i.e. there may be or may not be a delay between the time periods t2 and tl as well as t3 and t2.
- a further operation of the filling system includes that steps a) - m) are followed by steps of:
- a preferred operation of the filling system includes that steps a) - k) or steps n) - s) are followed by steps of:
- the total amount filled is found and may then be compared with a predetermined minimum amount, maximum amount, etc.
- Another preferred operation of the filling system includes that a ratio of the predetermined amounts A2 and A3 defined as (A3-A2)/A3 is less than 0.25, preferably less than 0.1 and more preferred between 0.001 and 0.1.
- the first predetermined amount A2 is quite close to the second predetermined amount A3, whereby filling until the amount A2 is reached is a top-up filling.
- Reaching A2 may bring the filling close to a desired end amount, and a small top-up amount is calculated and filled which provides a precise method of reaching said desired end amount.
- a further preferred operation of the filling system includes, while the transport unit is passing a weighing section of the track, a prior step of weighing the transport unit to obtain a tare mass of the transport unit. Any spilled substance or other generally undesired matter randomly present on the transport unit may hereby be compensated for in the filling operation.
- a yet further preferred operation of the filling system includes, between steps a) and b), intermediate steps of:
- the filling may hereby be compensated according to the calculated residual substance, which is often present when refilling containers for LPG and other gasses, wherein the residual substance may be of an acceptable quality.
- the invention is described in further details below and with reference to the appended figures.

The invention may, however, also be employed in other applications. Figs.
- FIG. 2 and 3 display a container 1 supported by a container carrying part of a transport unit 1 and filling means 3 provided for filling a substance into the container 1.
- a wheel is arranged between the transport unit 2 and the track 5 to provide a movable support 10 for 5 the transport unit such that the weight of the transport unit 2, the container 1, the filling means 3 and any present substance is supported largely by the support 10 and transmitted directly to the track 5 and from there to an electronic scale 6 (figs. 4 and 5) comprising a weighing cell 16.
- An electronic scale 6 (figs. 4 and 5) comprising a weighing cell 16.

- FIG. 2 shows that two supporting arms 10 11 are hinged with hinges 15 to the transport unit 2 in one end and hinged to a central section 12 of the driving means in an opposite end, whereby the transport unit 2, a set of two arms 11 and the central section 12 structurally form a parallelogram which supports the transport unit 2.
- Fig. 4 and 5 display the filling system without transport units 2 and filling means 3 for showing information regarding the electronic scales 6 and weighing sections 7 of the track 5.
- Containers 1 are transported to the filling site by a conveyor 14 and enter at a position 9 and exit at a position 8.
- the electronic scales 6 are in Fig. 4 incorporated in two separate sections of the track to provide individual weighing sections 7a and 7b, which are
- Each electronic scale 6 preferably comprises one or more electronic weighing cells 16, depending on the size and dimensions of the weighing section.
- the weighing sections 7a and 7b are arranged to weigh the transport units 2 individually, including any present containers and substance, while the transport units 2 are passing the weighing sections 7a and 7b while being moved by the driving means 4,
- the operation of the filling system includes operations in relation to weighing information obtained from the weighing sections 7a and 7b.
- a transport unit will first pass a first weighing section 7a where the weight of a transport unit is determined individually, including any present containers and substance, while the transport unit 2 is passing said first section 7a.
- a while later the transport unit will pass the second weighing section 7b,
- Another weight determination is performed. From the two individual weighings it may e.g. be calculated how much the total weight has increased between the two weighings, whereby an indication is obtained with respect to an amount of substance filled between the two weighings.
- Fig. 5 the system involves five scales 6 and five individual weighing sections 7a-7e, which are incorporated in separate sections of the track 5 to provide individual weighing sections distributed along the track 5.
- This displayed system in fig. 5 is preferably adapted for filling LPG gas in recycled gas bottles.
- Each electronic scale 6 preferably comprises one or more electronic weighing cells 16, depending on the size and dimensions of the weighing section.
- the weighing sections 7a - 7e are arranged to weigh the transport units 2 individually, including any present containers and substance, while the transport units 2 are passing the weighing sections, while being moved by the driving means 4, 12.
- the operation of the filling system includes operations in relation to weighing information obtained from the weighing sections 7a - 7e.
- a transport unit 2 at a position 9 receives a container 1 to be filled. Before the container 1 is received, the tare weight of the empty transport unit 2 is determined at a weighing section 7e. This is done after a filled container has been unloaded at an exit position 8. The transport unit 2 will then pass a weighing section 7a, where the weight of the transport unit 2 and the container 1 is determined, including any residual substance present in the container, while the transport unit 2 is passing said section 7a. At a previous occasion the individual tare weights of the containers have been determined and the information is stored in the control system controlling the filling operation.
- the weight obtained at section 7a is compared with the stored information regarding the tare weight of the container 1 and the tare weight of the transport unit 2 determined at section 7e in order to calculate the presence and amount of any residual substance in the container 1. This information is used to determine how much substance is needed to fill the container to a predetermined level. Filling is now started and the starting time is registered. A while later the transport unit 2 passes weighing section 7b, where a weight determination is performed and the time passed since filling began is registered. A flow rate of the filling is determined from the filling time and the amount filled. This is used to extrapolate necessary filling time to obtain a first filling level to be reached before a further weighing is performed at section 7c. Filling is started again and the starting time is noted.
- the filling is stopped.
- the total weight is determined at section 7c, where a flow rate is determined for the filling performed between section 7b and 7c.
- the amount of substance filled up to this point is compared to a predetermined second filling level and a second calculation in the form of an extrapolation is made to determine a necessary filling time for reaching the second filling level based on the flow rate.
- Filling is started again and the starting time is noted.
- the second extrapolated filling time runs out, the filling is stopped.
- the total weight is checked at section 7d to verify that the amount of substance present in the container is within a predetermined tolerance interval.
- a further preferably short filling may additionally be performed before unloading, or the container 1 may be given an extra filling cycle by passing sections 7e and 7a-7d again to obtain a correct amount of substance. In the latter event, no tare weight is obtained in section 7e, since this was already obtained previously. The filled container 1 is unloaded at position 9, and the transport unit 2 is ready to receive a new container after its tare weight has been obtained at section 7e.
- Example 1 In a filling system according to the invention including five weighing sections the following steps are performed to fill 8,000 g (8 kg) of LPG into a gas bottle:
- the transport unit and the container are weighed together on a second weighing section and have a total mass of 40,570 g,
- the transport unit, the container and the LPG content are weighed together on a fourth weighing section and have a total mass of 47,899 g,
