Definitions
- This invention relates to an automatic combination weighing apparatus comprising a supply conveyor unit, a conical dispersion table, first conveying means to cause arti- cles fed from said dispersion table to move outwardly and circumferentially thereon, a plurality of feed troughs arranged around said conveying means to receive articles from said dispersion table, and in connection with said feed troughs a plurality of second conveyor means for advancing articles thereon towards the front end thereof, a plurality of pool hoppers below the front ends of said conveyor means, a plurality of weighing means positioned below said pool hoppers, each weighing means including at least a weighing hopper and a weighing mechanism, control circuit means coupled to said weighing means for calculating combinations of weights on the basis of values of weight of articles measured by said weighing means wherein the sum weight of the combination of articles is equal to or closest to within a preset range of allowance to a predetermined weight value of a measured portion of articles, and means for discharging articles from the weighing
- the most essential factors influencing on said important parameters are: -the necessity of an effective distribution of the items so they approach the pool hoppers in a uniform layer. This is best achieved by having as long a vibrating way of transport as possible, i.e. a dispersion table with as large diameter as possible, and long second conveyor means between the periphery of the dispersion table and the pool hoppers.
- any contamination will end in the product zone together with the measured batch.
- the weighing units comprising said pool hoppers, weighing hoppers and weighing cells, are extending outwardly from the body of the apparatus, and thus being located outside the product zone, which provide for easy access in connection with making service on said items.
- the feed troughs, radially extending from the periphery of the dispersion table, and the vibrating means in connection therewith are located in the product zone, and are thus exposed to contamination of the products supplied from the dispersion table.
- the location of said vibrating means in the body zone makes it very difficult to make service. Further does the disclosed apparatus not provide a long vibrating distance of transport before dispensing, and neither a short steep tapering distance of the walls of the chute through which the batches are supposed to slide to away from the weighing apparatus.
- the second conveying means in connection with each trough consists of at least one vibrator means for driving said items in the troughs in an inclined linear reciprocating vibrating motion, advancing them to the front end thereof.
- the troughs and the second vibrating means are integrated.
- the first conveying means below said dispersion table to cause articles fed on said dispersion table to move outwardly and circumferentially thereon consists of a cricoid shaped vibrating distributor, which performs spiral reciprocating vibratory motion, as stated in claim 4.
- the surface of the vibrating distributor extends at least from the edge of the conical dispersion table to the feed troughs, and the items are transported horizontally and circular along the outer edge of the cricoid shaped vibrating distributor. This means that if one or more openings of the troughs are closed, the items will not clog, but be transported to the next open trough, and pass on to the pool hoppers via the second conveying means.
- the items are transported from the center of the weighing apparatus to its periphery and down into the troughs and further via the second conveying means to the pool hoppers, located in a circle close around the center axis of the chute.
- the second conveying means to the pool hoppers, located in a circle close around the center axis of the chute.
- the dispersion table is rotating during the dispersion of items.
- the level of articles supplied from the supply conveyor to be dispensed in portions in the automatic combination weighing apparatus according to the invention is controlled by a level control.
- the level control comprises e.g. photoelectric cells located at the periphery of the first conveying means and/or a weighing cell on said first conveying means, said photoelectric cells and/or weighing cell being connected with the con- trol circuit means, which is also connected with the supply conveyor to control the supply velocity/volume/amount of articles, where said control circuit means in case of registered deviations from a preferred level/weight of articles on the first conveying means, will adjust the supply velocity/volume/amount of articles, supplied from the supply conveyor.
- the supply conveyor unit comprises the conical shaped dispersion table located below the front end of the supply conveyor, said conveyor unit being mounted on a pivot joint and/or displaceable on a rail system, for the displacement of the supply conveyor unit and the dispersion table away from the center of the weighing apparatus, as stated in claim 5.
- This feature provides for full access to the entire top side of the weighing apparatus, as the conical shaped dispersion table and the supply conveyor can be displaced to a location outside the top side.
- the body can be shaped as a hollow, preferably rectangular ring, surrounding the product zone, on which body are mounted pool hoppers and weighing hoppers extending towards the center axis of the weighing apparatus.
- This opens for a more stable and rigid construc- tion of the carrying parts of the weighing apparatus, since these are not to be arranged in the product zone in the center of the apparatus, where the space for such constructions are narrow.
- vibrations from the vibrating means of the first and second conveying means will not propagate and influence the weighing cells. Further there is provided enhanced access to the sensitive, and the mechanical parts of the weighing apparatus.
- the shape of the body opens also for a more appropriate location of the vibrating means of first conveying means and the second conveying means as it will be possible to locate these outside the product zone. This will enhance the access to these me- chanical parts in connection with service, and further these parts will not be expelled to contamination of the articles.

- Fig. 2 shows the same as in figure 1, bur with the supply conveyor and the dispersion table displaced apart from the top side of the weighing apparatus
- Fig. 3 is a top view of the combination weighing apparatus in figure 1
- Fig. 4 is a top sectional view along the line A- A, in figure 1, showing the upper surface of the first vibrating conveying means
- Fig. 5 is a top sectional view along the line B-B, in figure 2, showing a top view of the troughs and the second vibrating conveying means
- Figs. 6 & 7 are schematic diagrammatical views of the combination weighing appara- tus shown I figure 1 , in different operating positions.
- Fig. 1 shows on diagrammatical form an embodiment of the combination weighing apparatus 2 according to the invention comprising a supply conveyor unit 4 for supplying the weighing apparatus 2 with articles 10.
- a supply conveyor unit 4 for supplying the weighing apparatus 2 with articles 10.
- a conical shaped dispersion table 6 which preferably is rotably connected to said supply conveyor unit 4.
- the dispersion table 6 might comprise a driving unit (not shown) to perform a rotably movement during dispersion of articles.
- a circular shaped vibrating distributor 8 which performs spiral reciprocating vibratory motion, transporting the items 10 towards feed troughs 12 located along the periphery 13 of said vibrating distributor 8.
- the distributor 8 causes a movement of the articles 10, in a direction illustrated by the arrows 11 in figure A, showing the upper surface 9 of the first vibrating conveying means 8.
- the direction of movement 11 of the articles 10 causes a longer distance of vibrating transport, which provides for a better straightening out the items to be feed to the second conveyor means 14, in connection with the feed troughs 12.
- the second conveyor means 14 in connection with each feeding trough 12 consists in the shown embodiment of one vibrating means 14 (the second conveyor means 14 and the their respective feeding troughs 12 are integrated), driving the articles in an inclined linear reciprocating vibrating movement, advancing them to the front end 16, as it appears from figure 1.
- the vibrating means 14 are, as it appears from figure 3 and 5, extending in an oblique manner against the vertical center axis 30 of a chute 28 disposed at the lower end of the automatic weighing apparatus 2.
- Below the front ends 16 of each said vibrating means 14 are located pool hoppers 18 arranged in a circle.
- the outlet openings 19 of said pool hoppers 18 are located above weighing hoppers 22, also arranged in a circle.
- Said weighing hoppers 22 stands in connection with weighing mechanisms 24, attached in a known manner to control circuit means 26, for calculating combinations of weights on the basis of values of weight of articles 10 measured by said weighing means (20) wherein the sum weight of the combination of articles (10) is equal to or closest to within a preset range of allowance to a predetermined weight value, and for discharging articles to the weighing hoppers (22) of the weighing means (20) corresponding to the predetermined weight value.
- a chute 28 for the receive of portions of measured articles 10 to be carried on to e.g. a not shown packaging device.
- Said chute 28 has a short steep tapering wall 42, on which the measured portions 32 of articles 10 passes. This provides for the preferred short steep sliding distance for the articles in an acute angle, and thus for increasing the capacity of the weighing apparatus according to the invention.
- FIG. 3 shows the directions of vibrating movement of the articles 10 between the supply conveyor 14 and the pool hoppers 18.
- figure 4 is the direction of vibrating movement of articles supplied from the disper- sion table 6 shown by the arrows 11, as a combination of a radial movement from the center 30, and a parallel movement with the periphery 13 of the vibrating conveyor 8.
- figure 6 and figure 7 is the automatic combination weighing apparatus 2 shown in operation.
- FIG 6 is shown how samples 32 of measured articles are discharged via the outlet openings 23 of the weighing hoppers 22 into the chute 28, and with simultaneous loading the pool hoppers 18 with articles via the second vibrating conveying means 14.
- FIG 7 is shown how successive samples 32' are discharged to the weighing hoppers from the pool hoppers 18 via the opened outlet opening 19, and where the previous samples 32 of articles 10, are sliding downwards on the short steep tapering wall 42 towards the discharge opening 40 in the chute 28.
- the mechanical parts such as the second vibrating means 14, the weighing mechanisms 24, and other mechanical features necessary for the weighing apparatus, are located on the inward facing side 46 of the body 36, the technical parts of said mechanical features extending into the hol- low body 36, and openings in the outward facing side 44, provides for a excellent accessibility to these parts in connection with repair works and service. Further and very important, the mechanical parts are located outside the product zone 38, and thus, these parts are not expelled to contamination of the articles 10 supplied via the supply conveyor 4.
- Said arrangement of the mechanical parts makes cleaning up the automatic combination weighing apparatus 2 much easier, since the mechanical parts does not take up space in the product zone 38, thus there will be full access to the product zone 38, and accordingly the pool hoppers 18, the weighing hoppers 22 and the inside of the chute 28. Further the excellent accessibility to the mechanical parts makes it possible to make repairs on one or more of the mechanical/technical features, taking these out of operation, without the necessity of closing down the entire operation with the automatic weighing apparatus according to the invention.
- the body enable an efficient support of all parts of the automatic combination weighing apparatus 2 according to the invention, without the necessity of legs, beams or supports extending through intermediate wall constructions in chutes or the like.
