Technical Field
The present specification relates to methods and systems for weighing and collecting solid food products having an adhesive coating.
Background
In industries such as the food industry weighing systems have been described in publications such as US6015049, WO9849892, US5526437, US4569434, EP0909601 and WO12104404, all of which are incorporated herein by reference and into the present specification.
In the food industry, there is a need to sort products or items according to various physical characteristics, such as size, color or weight, or by any combination of these, at high speed or high throughput.
Accordingly, many solid food packages include more than individual products, i.e., the package typically includes at least two solid food products. product packages, such as chicken breast packages, typically include three pieces in each package, however, the number can be larger, such as four or five pieces in the same package, so long as the packages all have approximately the same weight.
To ensure that different weights of food items can be combined in packages having approximately the same weight, a multi-head scale may be used.
examples of solid food products (as opposed to liquids) are poultry, while examples of viscous coatings are marinades.

Detailed Description
These aspects may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like reference numerals refer to like elements throughout. Therefore, the same elements will not be described in detail with respect to the description of the respective drawings.
Fig. 1 shows a perspective view of a
The multi-head scale includes a receiving
During operation of the multi-head scale, when solid food products are received from above, the solid food products are generally randomly dispensed onto the receiving section, and due to gravity and the tapered shape of the receiving section, the solid food products will slide downward at the bottom end of the receiving section toward the periphery of the receiving section.
The receiving section may be selectively rotated or vibrated to more evenly distribute the food product along the perimeter of the receiving section and to avoid any food product from remaining on the receiving section for longer periods of time.
Sixteen pool hoppers (feed conveyors) are positioned around the perimeter of the receiving section, along the ring and up to 360 ° around the receiving section, without suffering any interruption, such as parts of the frame system for supporting the conveyor structure used in conjunction with a multi-head scale.
Each pool hopper comprises a feed channel in which a
Solid food products entering the receiving section will be randomly distributed in the pool hopper.
When the solid food products enter the inlet end of the pool hoppers, they are carried by the auger along the feed path toward the outlet end and discharged into the weighing hopper constituting the
The multi-head scale includes receptacles for each well hopper, well hopper and receptacles together constitute a scale head accordingly, there are sixteen receptacles (up to nine receptacles can be seen in the perspective view of the multi-head scale shown in FIG. 1).
The separate receiver will be described in more detail in connection with fig. 2.
Further below the plane of the receiver is a collector, which may be of the four different collectors described more closely in connection with fig. 4 a-4 e.
Fig. 2 shows an enlarged perspective view of
The receiver is supported by the receiver support.
The receiver has a shape similar to a hollow half cylinder, i.e., it is defined by an th end wall 22 and a second end wall 24 opposite the th end wall.
The th axis 36 extends through the th end wall and the second end wall.
Between the th end wall and the second end wall is a bent rectangular receiver wall, i.e. the receiver wall has an inner surface constituting a cylindrical surface with a rotation axis coinciding with the th axis.
The inner surface extends angularly about the axis from the edge 32 to the second edge 34 at a angle phi, the angle being 170 deg. (or about 170 deg., such as 179 deg. or 178 deg. or 177 deg., or within 170 deg. + -9 deg. or 170 deg. + -8 deg. + -170 deg. + -7 deg. + -170 deg. + -6 deg. or 170 deg. + -5 deg.). this means that the receptacle is open, i.e., solid food product can fall into the receptacle in the receptacle opening between the th edge and the second edge.
The receiver may be oriented such that the axis is parallel or substantially parallel to the feed channels, each feed channel of the pool hopper having a second axis extending through the inlet end and the outlet end.
The receiver is rotatably mounted to the receiver support such that the receiver is rotatable about an th axis.
The rotation and orientation of the receptacle and the discharge of the solid food product from the pool hopper are controlled such that the opening is upward when the solid food product is discharged from the pool hopper.
If a plurality of receptacles have solid food products with a combined weight suitable for batching and packaging in a package at target weight , the respective receptacles are rotated upside down so that the solid food products fall out and into a collector located below the receptacles, the different collectors will be described in more detail in connection with fig. 4 a-4 e.
The multi-head scale is used to handle solid food products having an adhesive coating that may adhere to the interior surface and possibly to the th and second end walls.
The scraper has a scraper edge contacting the inner surface the scraper edge is less than 10 ° proximal to said th edge, i.e. the scraper edge is less than 10 ° from the th edge.
The scraper is U-shaped such that the base of the scraper scrapes the inner surface, the th leg of the scraper scrapes the inside of the th end wall, and the second leg of the scraper scrapes the inside of the second end wall.
The scraper is supported by the scraper mount and is stationary as the receiver rotates about axis .
The receiver is connected to an actuator that rotates the receiver such that the inner surface moves along the scraper until the second edge reaches the scraper edge, wherein the receiver has been rotated 170 ° minus the angle (less than 10 °) of the scraper edge away from the th edge.
Alternatively, the receptacle may continue to rotate and rotate straight, thereby being ready to receive a continuous solid food product.
Fig. 3 a-3 c show perspective views of
In fig. 3a the receptacle is facing upwards, i.e. the receptacle opening is facing upwards, and the
In fig. 3b the receptacle has been rotated about 30 °, i.e. the second edge has moved closer to the scraper edge than the position in the receiving mode, and the th edge has moved further away from the scraper edge than the position in the receiving mode, the receptacle has been said to have entered the second mode/state of operation constituting the discharge mode when it has the position shown in fig. 3 b.
In fig. 3c the receptacle has been rotated so that it is more or less upside down, i.e. with the receptacle opening facing downwards, a cross section of the receptacle with a normal parallel to axis will show that the receptacle is concave, the second edge is moved until meeting the scraper edge, in this way the area of the inner surface between the line (where the scraper edge is in contact with the inner surface in the operating mode) and the second edge is scraped.
The solid food product will be discharged from the receptacle due to a combination of gravity and the solid food product being pushed by the receptacle wiper.
When the receiver is emptied, it rotates back to the position it was in the th mode of operation described in connection with fig. 3 a.
The receptacles cycle between th and second modes of operation as successive solid food products are discharged from the outlet end of the feed head above the respective receptacle.
Fig. 4a shows a perspective view of a
As described in connection with fig. 1, the collector is located below a multi-head scale, which may be of the type described in connection with fig. 1. The multi-head scale is not shown in fig. 4 a.
The collector is formed as an annular compartment having an upwardly facing th opening for receiving solid food products discharged from the receptacle located above the annular compartment.
The amount of discharged solid food depends on the weight of the individual solid food and the target weight of the packaging in which the amount of solid food is to be batched and packaged, i.e. the target weight may be in the range between e.g. 100g and 10 kg. In fig. 4a, two solid food products have been discharged into the receptacle.
The ring-like compartment has a center that coincides with a vertical axis that also passes through the center of the multi-head scale, i.e., the center is along a common vertical axis at different heights.
The th opening is defined by two concentric side walls extending upwardly from the
The radial distance between the inner and outer walls (the width of the compartment) is greater than the distance between the th end wall 22 and the second end wall 24 so that the solid food product does not fall outside the collector when discharged from the feeding and weighing system.
The collector has
The collector also has a dividing
In the th embodiment of the collector, the dividing wall can move in and out of the annular compartment in either a horizontal or vertical direction when the dividing wall is within the annular compartment, the dividing wall is adjacent the fourth edge.
In a second embodiment of the collector, the partition wall is fixed. In a second embodiment, the partition wall is adjacent to the fourth edge.
A third embodiment of the collector 40' is described in connection with fig. 4b, in which the partition wall is replaced by a second scraper.
A fourth embodiment of a
Returning to the embodiment, the two solid food products that have drained into the collector will be collected and drained from the collector, to this end, the dividing wall is removed from the annular compartment and does not interfere with the scraping member, the dividing wall is connected to an actuator for moving the dividing wall into and out of the annular compartment, the scraping member is then moved from a position adjacent the third edge, through the second opening and past the position where the dividing wall is located, and can begin to scrape the bottom wall of the annular compartment.
The th wiper has a
The th scraper has a second scraper edge for scraping the bottom surface of the annular compartment the th scraper also has a third scraper edge and a fourth scraper edge for scraping the surface of the inner and outer walls, respectively.
When the th wiper scrapes the annular compartment, the dividing wall returns into the annular compartment.
On the way around the annular compartment, the th wiper collects both solid food products and moves back to a position at the third edge.
When two solid food products are collected, the th wiper forms an evacuation compartment within the annular compartment at the th edge together with the separation wall , and the
The collected solid food product is then discharged from the discharge compartment through the second opening. This is achieved by displacing the piston in the radial direction. At the same time, the piston scrapes the bottom and side surfaces of the discharge compartment, leaving as little viscous coating as possible in the discharge compartment. This process constitutes the discharge mode.
The surface of the partition wall facing the discharge compartment is in a vertical plane, which is parallel to the direction of movement of the piston, so that the piston can scrape the surface of the partition wall facing the discharge compartment (when the collector is in the discharge mode).
The th face faces the discharge compartment in the discharge mode and is in a plane parallel to the direction of movement of the piston, i.e. in a plane parallel to the radial direction along which the piston moves, which means that the radial direction does not intersect this plane.
The th wiper has a thickness (measured in the angular direction) that increases from the inner wall to the outer wall.
The piston has fifth, sixth and eighth scraper edges for scraping the bottom wall, the partition wall and the th face, respectively.
After the discharge compartment has been emptied, the collector is ready to receive a continuous quantity of solid food products discharged from the plurality of receptacles (receiving mode).
The collector according to embodiment cycles between a receiving mode, a collecting mode, and a discharging mode the collector according to embodiment can be in both the receiving mode and the discharging mode.
In a second embodiment (where the dividing wall is permanently fixed at the third edge), the th wiper rotates back and forth.
After the discharge compartment is emptied (and before successive quantities of solid food particles are discharged into the annular compartment), the th scraper is rotated in a scraping direction away from the second edge in a reverse direction and turned to a position adjacent the dividing wall.
The collector according to the second embodiment cycles between a receiving mode, a collecting mode and a discharging mode. The collector according to the second embodiment cannot be in the receiving mode and the discharging mode at the same time.
Fig. 4b shows a perspective view of a collector 40' for collecting a plurality of solid food products which have been emptied from a corresponding number of
As described in connection with fig. 1, the collector is located below a multi-head scale, which may be of the type described in connection with fig. 1. The multi-head scale is not shown in fig. 4 b.
In contrast to the collector according to the th embodiment, the collector according to the third embodiment has second wipers instead of partition walls the second wipers are identical to the th wiper moreover, each of the th and second wipers has a
The second scraper further has a tenth scraper edge and a tenth scraper edge for scraping the surface of the inner wall and the outer wall, respectively.
In fig. 4b, the collector is in a state where the th wiper is located near the third edge, with the th face facing the discharge compartment and the th back face facing the opposite direction.
The second scraper is located near the fourth edge and the second rear face faces the discharge compartment and has a second face facing in the opposite direction (away from the discharge compartment).
The second back face is in a vertical plane that is parallel to the direction of movement of the piston so that the piston can scrape the second back face (when the collector is in the discharge mode).
the scrapers and the second scrapers are interchangeable, i.e. during operation of the collector according to the third embodiment, the collector alternates between scraping the annular compartment with the scrapers and the second scrapers the th scrapers rotate with the second scrapers only in the scraping direction.
In order to collect the two solid food products that have been discharged to the collector in fig. 4b, the second scraper is rotated in a scraping direction away from the position at the fourth edge, at the same time, the th scraper is rotated in a scraping direction away from the position at the third edge, through the second opening and to the position at the fourth edge, where,
the second scraper is pre-positioned before the start of scraping the annular compartment.
In contrast to the previous discharge mode, the two scrapers have now changed position, i.e. the th back face is in a vertical plane parallel to the direction of movement of the piston, so that the piston can scrape the th back face, and the second face faces the discharge compartment.
The collector according to the third embodiment cycles between the receiving mode, the collecting mode and the discharging mode. The collector according to the third embodiment can be in the receiving mode and the discharging mode at the same time.
Fig. 4c shows a perspective view of a
As described in connection with fig. 1, the collector is located below a multi-head scale, which may be of the type described in connection with fig. 1. The multi-head scale is not shown in fig. 4 c.
The collector according to the fourth embodiment additionally has second scrapers compared to the collector according to the embodiment the second scrapers are identical to the scrapers.
In fig. 4c, the collector is in a state where the th wiper is located near the third edge with the th face facing the discharge compartment, the separation wall is located in the annular compartment, and the second wiper is adjacent the separation wall on the opposite side of the separation wall from the th wiper.
The two solid food products that drain into the collector will be collected and discharged from the collector, for which purpose the second scraper rotates in a scraping direction away from the position adjacent to the partition wall, at the same time the partition wall is removed from the annular compartment and does not interfere with the th scraper the th scraper then moves from a position adjacent to the third edge, through the second opening and past the position where the partition wall is located, this is shown in fig. 4d, where the image of the partition wall is shown in a dashed circle as it has been removed from the annular compartment.
The dividing wall is then moved back into the annular compartment again, and the th wiper is positioned adjacent to the dividing wall.
In contrast to the previous discharge mode, the two scrapers have now changed position, i.e. the second scraper has a second face facing the discharge compartment, said second face being in a vertical plane parallel to the direction of movement of the piston, so that the piston can scrape the second face.
Finally, the piston can discharge the collected solid food product out of the compartment through the second opening, which is shown in fig. 4 e.
the scraping members scrape the annular compartment in turn with the second scraping members.
