Description

The present invention relates to a tray assembling method for sliced meat pieces of meat, and in particular, relates to a placing method for discharging a tray on which sliced meat pieces having a fat portion ratio outside an allowable range are discharged from a conveyor.

Japanese Patent Application Laid-Open No. H10-228707 discloses a technique for detecting a lean portion and a fat portion by using a photoelectronic unit on a cut surface of a sliced meat piece group, and providing a weighting coefficient for each of them.

At present, sliced meat pieces cut out from the slicer are manually placed on the tray, and the proportion of the fat portion occupying the sliced meat pieces allowed is discriminated visually.
When slice meat pieces cut out from the slicer are dropped directly into the tray as shown in the present invention, the ratio of the fat portion of the slice meat pieces to be placed on one tray is a product as a product. Exceeds the allowable range of.
In addition, in sliced meat pieces that are partly stacked and placed on a tray, or in a piece of komagire meat in which small pieces of meat are gathered, the sliced meat pieces are polymerized and sold from above without confirming the proportion of the fat portion. Happens.

In the present invention, when automating the placement of sliced meat pieces on a tray, the fat portion ratio that is outside the allowable range can be reliably discharged without reducing the work speed so as not to be conveyed to the next process. The object is to provide a method for tray mounting of sliced meat pieces.

In the present invention, a belt conveyor that receives sliced meat pieces intermittently cut out from a slicer in a substantially expanded state and conveys them in the cutting direction, and a tray that supplies the tray to a serving position below the end of the belt conveyor. In the apparatus for stacking slice meat pieces with the supply means and the transport conveyor for transporting the tray on which the sliced meat pieces are stacked to the next process, the fat portion on the cut surface of the sliced meat pieces being transported by the belt conveyor When the proportion of fat in the sliced meat pieces arranged on one tray is determined to be outside the allowable range by detecting the proportion occupied by the sensor, the tray is transported with the sliced meat pieces arranged. Tray stacking of sliced meat pieces characterized by being discharged by sorting means provided on the conveyor To achieve the purpose by the law.
In addition, the sliced meat piece is a piece of chopped meat, and the amount of chopped piece of meat cut at a time is used as a unit and is placed on the tray. The proportion of fat detected by the sensor is cut out on a single tray. It is preferable to discriminate by the average value for the number of times.
Furthermore, it is preferable that a sorting unit that is provided on the transfer conveyor and receives a signal from another detection unit to discharge the tray is used as the sorting unit.

According to the method for stacking sliced meat pieces according to the present invention, since the ratio of the fat portion is detected in a state where the sliced meat pieces are substantially widened, the sliced meat pieces in which the proportion of the fat portion is outside the allowable range are accurate. Since the stacked trays are discharged from the conveyor by the sorting means, the quality is improved.
In addition, since the entire tray is discharged, the working speed is not reduced, and even soft raw meat is not discharged onto the conveyor and is reliably discharged.
In addition, the distribution means becomes simple when a distribution means for discharging the tray based on another detection result is used.

  It is a top view of the Example of the arrangement apparatus used for this invention.   It is a side view mainly of a slicer.

With reference to FIGS. 1-2, the Example of the tray mounting apparatus of the slice meat piece used for this invention is described.
The meat slicer S (hereinafter simply referred to as slicer) provided for the present invention is not particularly limited, but the basic configuration in this example is disclosed in Japanese Patent Application Laid-Open No. 2011-115931 by the present applicant. Since what has been described is diverted, the details will be omitted and only the main points will be described.
The meat box 1 is supported so as to be able to swing up and down within a certain angle range in the vicinity of the horizontal position around a support shaft 3 integrally protruding from the left and right side walls of the rear portion of the machine base 2.
At the bottom of the meat box 1, a bottom conveyor 4 is laid across the width from the rear to the outlet, and is a widely used means, so that it is appropriately connected to a servomotor and driven, although not described in detail. In addition, side walls are erected on both the left and right sides of the meat box 1 from the rear part to the outlet, and an upper pressing member 5 is provided at an upper position near the outlet of the meat box 1. The upper pressing member 5 is not necessarily a conveyor but may be a simple flat plate. Further, the side wall may be a simple flat plate, but if it is constituted by a conveyor, the feeding performance is improved and the variation in slice thickness is reduced.

In this way, the outlet of the meat box 1 having the bottom conveyor 4 at the bottom, the side walls on both sides, and the upper pressing member 5 at the top is provided with a contact plate 6 that is adjusted in the feeding direction and regulates the slice thickness. It has been. A band knife 7 is hung around the upper end of the abutting plate 6 so as to be able to run in a horizontal direction with a cut-out opening, and is held in the meat box 1 when the meat box 1 reciprocating in the vertical direction moves up. The front end of the meat chunk in a state of being cut is cut out from the cut-out opening as a sliced meat piece by the band knife 7.

A belt conveyor 8 having a smooth surface as a transfer surface facing the start end is provided at a position below the cut-out opening of the slicer S. The belt conveyor 8 is extended to a loading position on a tray where sliced meat pieces, which will be described later, are loaded and stacked so that the belt conveyor 8 travels in the direction of being cut out after receiving the sliced meat pieces.

Next, a description will be given of a configuration relating to the laying of sliced meat pieces on the sales tray 9 on which the sliced meat pieces are placed, which waits at the laying position below the end portion of the belt conveyor 8.
On the transfer surface near the terminal end of the belt conveyor 8, a roller 10 for stripping the transferred piece of meat is brought close to or in contact with the transfer surface of the belt conveyor 8 so that the gap between the transfer surface is equal to or less than the thickness of the sliced meat pieces. It is provided so as to run in the direction opposite to the running direction of the belt conveyor 8.

There is provided a tray supply means 11 for transferring the tray 9 to a position where the sliced meat pieces are arranged at a position below the roller 10 and separated by a predetermined fall distance of the sliced meat pieces.
Since the configuration of the tray supply means 11 itself is a known technique, it will not be described in detail, but in this example, as shown in FIG. 1, it is provided so as to be orthogonal to the machine 2 of the meat slicer. 9 From the tray tank that is stacked and held in the vertical direction, the trays 9 are taken out one by one in accordance with a command from the control means in relation to the cutting out of the sliced meat pieces, and transferred to the loading position by a transfer tool composed of an endless belt.

The end portion of the belt conveyor 8 is configured to be able to reciprocate within a predetermined range within the width of the tray 9 along the traveling direction of the belt conveyor 8 by an appropriate mechanism.
Then, the end portion is moved together with the roller 10 in association with the cutting of the sliced meat pieces, and the sliced meat pieces are sequentially dropped and arranged at different locations in the tray for each amount cut out at a time. At this time, the end portion of the belt conveyor 8 can be stopped and dropped to a fixed position for placement, or the sliced meat pieces can be dropped and placed thinly and widely while being moved.

The tray 9 on which the sliced meat pieces are arranged in this way is taken over by the transfer conveyor 13 including the curve conveyor 12 and is transferred to the next process.
The transport conveyor 13 is provided with a rotatable stop plate 14 that receives a signal from the detection means, blocks the destination of the tray 9 being transported by the transport conveyor 13, changes the transport direction, and discharges it to the side. Distribution means 15 is provided.

In the present embodiment, the weighing means 16 of the tray 9 on which sliced meat is arranged is provided on the upper side of the sorting means 15 to determine whether the weight is within the allowable range. In this configuration, the stop plate 14 is rotated to the transport surface side of the transport conveyor 13 and is discharged to the side by sending a signal to 15. The measuring means 16 may be replaced with a foreign object detecting means.

Next, by detecting the proportion of the fat portion in the cut surface of the sliced meat piece that is the gist of the present invention, it was determined that the proportion of the fat portion of the sliced meat piece placed on the tray was outside the allowable range. A processing method in this case will be described.
The sliced meat piece cut out from the slicer S is transported along the receiving and cutting out direction in a state where the belt conveyor 8 having the start end approached the cutting out port is run so as to be related to the cutting speed and is substantially spread.
Above the belt conveyor 8, the proportion of fat in the cut surface of the sliced meat piece cut out at one time during conveyance (the proportion of the area of the fat in the area of the cut surface of the sliced meat piece) is detected. A sensor 17 (for example, Keyence Corporation image discrimination sensor IV series) is provided.
The sliced meat pieces in which the proportion of the fat portion is detected by the sensor 17 are arranged on one tray 9 every predetermined number of times of cutting, and the fat in the sliced meat pieces arranged on one tray 9 at this time If it is determined that the ratio of the portion is outside the preset allowable range, a signal is sent to the sorting means 15 so that the stop plate 14 is rotated to the conveying surface side and the tray 9 is discharged to the side.
Here, if the distributing means 15 is the same as the distributing means 15 that rotates the stop plate 14 by the signal from the measuring means 16 and discharges the tray 9, the configuration is simplified.
If necessary, another stop plate 14 may be provided at the opposite position so as to be discharged.

The sliced meat pieces cut out from the slicer S are usually a single piece of sliced meat obtained by slicing a relatively large single piece of meat, and the sliced meat pieces cut out intermittently by the sensor 17 one after another. A predetermined number of sheets are arranged on the tray 9 after the ratio of the portions is detected.
At this time, in setting the allowable range of the proportion occupied by the fat portion, since the number of sliced meat pieces to be placed on one tray is relatively small, an allowable range is set for the ratio in a single sliced meat piece, for example 3 If one of the stacked sheets is out of the permissible range, the tray is preferably discharged out of the permissible range, but can be set as appropriate.
In sliced meat pieces in which multiple pieces of meat obtained by slicing together and slicing together multiple pieces of small meat called komagire meat, they are arranged on the tray in units of the amount of piece of piece However, it is preferable that a permissible range is set and discriminated with respect to an average value of the number of cutouts arranged on one tray of the ratio of the fat portion detected by the sensor 17.

In any case, in the present invention, since the ratio of fat content in the cut surface is detected by the sensor while the sliced meat piece cut out from the slicer is substantially spread on the belt conveyor, it can be accurately detected.
In addition, the sliced meat pieces are dropped from the end of the belt conveyor 8 into the tray 9 and placed, and the proportion of fat in the process of transporting the tray 9 on which the sliced meat pieces are placed to the next process by the transport conveyor 13 is as follows. The tray 9 on which the sliced meat pieces outside the allowable range are arranged is discharged sideways by the sorting means 15 together with the tray 9 in which the sliced meat pieces are arranged, so that the operation speed is maintained as it is.
When sliced meat pieces are soft raw meat and sliced, it is difficult to attach sliced meat pieces that are outside the allowable range even if they are removed from the conveyor and difficult to handle in post-processing, but they will be discharged together with the tray. This can be easily done in the present invention.
