1 shows a sorting system according to the present embodiment.

As shown in Figure 1, the sorting system 100 of the present embodiment, the discharge conveyor 20 is disposed along the conveying conveyor 10, the conveying conveyor 10, the object is placed and conveyed, discharge portion 20 for discharging and discharging the object, discharge The return line 30 disposed on the exit side of the unit 20 and a weight measuring device 40 installed on one side of the transport conveyor 10 to measure the weight of the object moved to the discharge unit 20 may be included.

Hereinafter, the present embodiment will be described as an example of a sorting system for transferring a product using a free conveying tray (hereinafter referred to as a tray P) for measuring and sorting the weight of an object. This embodiment is, of course, also applicable to a structure for directly transporting and sorting products that are objects in addition to the sorting system using a tray.

Tray P can be understood as a container containing a product. Products such as apples and pears can be damaged if they bump into each other during the transfer. Tray P is transported along the conveying conveyor 10 in a state of wrapping each product such as an apple to prevent damage to the product.

The trays P are all made of the same shape and size, and are provided separately from the conveying conveyor 10 so as to be freely placed on the conveying belt of the conveying conveyor 10 and conveyed. The tray P is, for example, a container structure of a circular cross-sectional structure having a flat bottom to be placed on a transport belt of the transport conveyor 10, and has a space in which a product is accommodated.

The conveying conveyor 10 is driven by a support frame 12 installed on the floor of the facility, a rotating belt 14, a drive pulley and driven pulley for rotating the conveying belt 14, the driven pulley, the drive pulley to rotate the rotation It may include a drive for making. The conveying belt 14 is continuously rotated according to the driving of the driving pulley. Thus, the tray P placed on the conveyance belt 14 is conveyed along the traveling direction of the conveyance belt 14. The length of the transfer conveyor 10 or its arrangement may be variously modified depending on the equipment conditions and is not particularly limited.

In this embodiment, the conveyance belt 14 is adapted to sequentially move the tray P placed thereon at appropriate intervals. To this end, the transfer belt 14 may include a protrusion 16 installed to protrude on the surface and disposed at intervals along the moving direction of the transfer belt 14 to catch the tray P. Accordingly, the tray P supplied to the conveying conveyor 10 is sequentially moved one by one by the projections 16 installed along the conveying belt 14 to pass through the weighing device 40. The structure and operation of the protrusion 16 will be described later.

The discharge part 20 may include, for example, a plurality of ramps 22 disposed in the width direction perpendicular to the traveling direction of the transfer conveyor 10 and down which the tray P rides down. Thus, the discharge unit 20 may push the tray P from the transport conveyor 10 to the slope 22 at the entrance side of each slope 22 to discharge it. An ejector (not shown) may be provided on the conveying conveyor 10 to push the tray P laterally corresponding to the positions of the respective ramps 22. When the tray P, the weight of which is detected, moves on the conveyance belt 14 to reach the corresponding ramp 22 position, the ejector is driven to push the tray P to the ramp 22. The ramp 22 is provided in accordance with the number of classification by weight is disposed along the exit end of the conveying conveyor (10).

The discharge unit 20 calculates the tray moving distance according to the tray feed speed after measuring the weight of the tray P in the weighing device 40. When the tray P reaches the grade 22 corresponding to the measured weight, the ejector pushes the tray P to the grade 22. The tray P pushed away from the conveying conveyor 10 flows down to the exit side in the corresponding ramp 22 and is classified by weight. Accordingly, only the tray P having the same grade for each weight is collected on each of the inclined paths 22. The structure of the discharge unit 20 including the ejector 20 for pushing the tray P to the ramp 22 or the ramp 22 is variously modified and is not particularly limited.

The return line 30 may include a conveying conveyor disposed at the discharge portion 20 exiting side and transferring the tray P. The conveying conveyor may be connected to, for example, the inlet side of the conveying conveyor 10. Thus, the worker separates the product from the tray (P) descending the ramp 22 in the discharge portion 20, and only the empty tray (P) to the entrance side of the transport conveyor 10 through the return line 30 easily. Can be returned.

The weighing device 40 is located before the discharge unit 20 along the conveying conveyor 10 to measure the weight of the tray P, which is moved along the conveying belt 14, that is, the weight of the product loaded in the tray P. Measure Since the size and weight of all trays (P) are the same, the weight of the product can be accurately determined by excluding the weight of the tray (P) itself from the weight measured through the tray (P).

In the present embodiment, the weighing device 40 may be provided separately from the conveying conveyor 10 and may be installed at any position of the conveying conveyor 10. In the case of such a structure, the weighing apparatus 40 of this embodiment can be simply installed and used also in the sorting installation conventionally constructed. In addition, it is possible to freely arrange the weighing position along the conveying conveyor (10). Accordingly, the degree of freedom in designing the arrangement of the weighing device 40 can be increased, and the facility can be implemented in various forms according to the space.

As shown in FIG. 1, the weighing device 40 may be located immediately before the discharge part 20 of the conveying conveyor 10 along the tray P conveying direction. Thus, after measuring the weight of the tray (P) can be sorted out immediately, it is possible to minimize the total length of the installation, including the conveying conveyor (10).

2 shows a weighing apparatus according to the present embodiment.

The weighing apparatus 40 of the present embodiment is arranged along the conveying belt 14 of the conveying conveyor 10 to which the tray P is conveyed, and lifts the tray P conveyed apart from the conveying belt 14 upwardly. The measuring unit 42 is disposed at the rear end of the rising unit 41 along the moving direction of the conveying belt 14 of the conveying conveyor 10 and measures the weight of the tray P spaced apart from the conveying belt 14. ), Which is disposed at the rear end of the measuring unit 42 along the moving direction of the conveying belt 14 of the conveying conveyor 10 to lower the tray P spaced apart from the conveying belt 14 to the conveying belt 14. It may include a lower portion (43).

Thus, the tray P is measured in the measuring unit 42 in the state of lifting from the conveying belt 14 by the rising unit 41 in the process of moving on the conveying belt 14. And it is placed in the original state on the conveyance belt 14 along the lower portion 43 is conveyed to the discharge portion (20). Therefore, since only the tray P is placed on the measuring unit 42 without interfering with the conveying belt 14, more accurate weight measurement is possible.

The weighing device 40 of the present embodiment has a frame 45 in which the rising part 41, the measuring part 42, and the lowering part 43 are installed so that the weighing device 40 can be disposed separately from the conveying conveyor 10, and the frame. It may further include a support 46 installed on the 45 and supported on the equipment floor to position the frame on the transfer belt 14 at any position of the transfer conveyor 10.

Thus, the weighing device 40 of the present embodiment may be installed upright on the installation floor at a desired position by the support 46 separate from the transfer conveyor 10.

As shown in FIG. 2, the frame 45 may have a structure extending from the lower portion of the transfer conveyor 10 to both side ends in the width direction. The rising part 41, the measuring part 42, and the lowering part 43 are provided in the both sides of the frame 45, respectively. The support 46 is installed under the frame 45 to support the frame.

Since the weighing device 40 is disposed separately from the conveying conveyor 10, the vibration or shock caused by the conveying conveyor 10 is not transmitted to the weighing device 40. Therefore, the weight of the tray P can be measured more precisely without being affected by the transport conveyor 10.

3 and 4 show still another embodiment of the weighing apparatus, in which the weighing apparatus is fixed to the support frame of the conveying conveyor.

Except that the weight measuring device 40 of the present embodiment is a structure that is installed in the support frame 12 of the conveying conveyor 10, the other configuration is the same as the structure described above. The same configuration will be described using the same reference numerals.

As shown, the weight measuring device 40 of the present embodiment may include a rising part 41, a measuring part 42, and a lowering part 43. In addition, the weighing device 40 may further include a fixing bracket 48 installed on the support frame 12 of the transport conveyor 10 to support the measurement unit 42.

The rising part 41 and the lowering part 43 may be directly installed in the support frame 12. The measuring unit 42 may be installed to the support frame 12 through the fixing bracket 48.

The dustproof pad 49 may be further installed between the fixing bracket 48 and the support frame 12. The anti-vibration pad 49 absorbs vibrations or shocks transmitted through the support frame 12 according to the transfer conveyor 10 and prevents the vibration pads 49 from being transmitted to the measuring unit 42 installed in the fixing bracket 48. Thus, even if the weighing device 40 is installed in the conveying conveyor 10, it is possible to measure the weight of the tray (P) more precisely through the measuring unit 42.

The rising part 41 is for lifting the tray P from the conveying belt 14 and may include a pair of upwardly inclined members 51 disposed at both ends along the width direction of the conveying belt 14. have.

The upward inclined member 51 has a structure in which the upper end is gradually inclined upward along the conveying belt 14 in the traveling direction to protrude above the conveying belt 14. The upward inclination means that the inclined upward direction with respect to the horizontal plane when the conveying belt is a horizontal plane. The upper end of the upward inclination member 51 may extend horizontally, such as a conveyance belt. The upwardly inclined member 51 is sufficient to be able to gently separate the tray (P) from the conveyance belt 14, the inclination angle of the upwardly inclined member 51 with respect to the horizontal plane or the upwardly inclined member 51 with respect to the conveyance belt (14). ) The degree of protrusion can be variously modified. The lower end of the upward inclination member 51 may extend to a position lower than the conveyance belt 14 height.

The upwardly inclined member 51 protrudes upwardly from the conveyance belt 14, so that the tray P moves up the inclined member 51 and moves away from the conveyance belt 14 in the process of moving on the conveyance belt 14. do. The pair of upward tilting members 51 are spaced apart to support both sides of the tray P. The tray P may be stably moved by riding two spaced up inclined members 51.

The lowering portion 43 is for lowering the tray P lifted from the conveying belt 14 back to the conveying belt 14, and is disposed at both ends along the width direction of the conveying belt 14 to form a pair. It may include a downward slope member 53.

The downward inclined member 53 has a structure in which an upper end protrudes above the conveyance belt 14 and gradually inclines downward along the advancing direction of the conveyance belt 14. Downward inclination means that when the conveying belt is a horizontal plane, it is inclined downward with respect to the horizontal plane. Upper ends of the downward inclination members 53 and 51 may extend horizontally, such as a conveyance belt. The downward inclination member 53 is sufficient if the tray (P) can be seated gently on the transfer belt 14, the inclination angle of the downward inclination member 53 with respect to the horizontal plane can be variously modified.

In the present embodiment, the downward inclination member 53 may have the same shape as the upward inclination member 51 and may be symmetrically disposed with the measurement unit 42 interposed therebetween. The downward slope member 53 is lowered below the end of the conveyance belt 14, so that the tray P moves down the downward slope member 53 in the process of moving on the conveyance belt 14, and the conveyance belt 14 ) The pair of downward slope members 53 are spaced apart to support both sides of the tray P. The tray P may be stably moved by riding two spaced downward inclined members 53.

The measuring unit 42 is for measuring the weight applied by the tray P. The measuring unit 52 is disposed at both ends along the width direction of the conveying belt 14 to form a pair of measuring table 52 and measuring table 52. It may include a load cell 55 is installed at the lower end for detecting the load applied to the measuring table 52. The measuring table 52 has a structure in which the upper end protrudes above the conveying belt 14 and the tray P is placed and freely flows in the vertical direction to transmit the load of the tray P to the load cell 55.

The measuring table 52 is disposed between the upward tilting member 51 and the downward tilting member 53. The measuring table 52 may be formed at a height equal to or less than an upper height of the upward tilting member 51. Thus, the tray P passing through the upward tilting member 51 can smoothly move upwards to the measuring table 52 without being caught by the measuring table 52.

The upper end of the measuring table 52 is formed horizontally. Accordingly, the tray P on the conveying belt 14 is moved upward along the inclined surface of the upwardly inclined member 51 and then placed in a horizontal state on the measuring table 52 so that the accurate weight is measured, and then the downwardly inclined member 53 is removed. It is moved downward and placed on the conveyance belt 14 again.

The specific configuration of the rising portion 41 and the lower portion 43 and the measuring portion 42 is the same as the embodiment shown in FIG. 2 as well as the embodiment shown in FIG. 4, the same reference numerals are used and the detailed description thereof Replace this.

The measuring table 52 is arranged at both ends along the conveyance belt 14 in the width direction to form a pair. In the embodiment shown in Figure 4, the connecting member 56 is installed between the lower end of the measuring table 52, the load cell 55 may be installed below the connecting member (56). Thus, the load of the tray P applied to both measuring table 52 is applied to the single load cell 55 through the connecting member 56 is detected.

In addition to the above structure, in the embodiment shown in FIG. 2, both measuring stands 52 are separated from each other, and load cells 55 may be installed between the lower ends of the measuring stands 52 and the frame 45, respectively. Thus, each load cell 55 can detect the respective loads on the measuring table 52 and finally calculate the load on each load cell 55 to detect the total weight of the tray P.

As mentioned, the transfer belt 14 may be formed with a projection 16 for pushing the tray P so as to continue to move up the spaced tray (P) is lifted up.

The projection 16 is installed to protrude on the surface of the conveyance belt 14 so that the side of the tray P is caught. In the present embodiment, two projections 16 may be formed in pairs and arranged at intervals along the width direction of the conveyance belt 14. Accordingly, the circular tray P is pushed in the same direction as the moving direction of the conveying belt 14 by the two projections 16 in a state of being lifted on the upward inclined member 51. In this embodiment, the protrusion 16 may be formed in a circular cross-sectional structure. Therefore, the contact area between the protrusion 16 and the tray P can be minimized. As the transport belt 14 is moved, the protrusion 16 moves the tray P in a state of being in contact with the tray P, thereby moving upwards of the measuring table 52.

As such, the contact between the protrusions 16 and the tray P is minimized, thereby minimizing the influence of the protrusions 16 in the process of measuring the weight of the tray P above the measuring table 52. Will be.

In the present embodiment, the protrusions 16 are arranged at intervals along the traveling belt 14 in the traveling direction. As shown in FIG. 5, the arrangement gap D between the protrusions 16 along the moving direction of the conveying belt 14 is formed to be longer than the length L of the measuring table 52 along the moving direction of the conveying belt 14. Can be. Thus, after the tray P caught on the one side protrusion 16 completely passes the measuring table 52, the tray P caught on the next protrusion 16 may be moved to the measuring table 52. Therefore, each tray P passes through the measuring table 52 without interference, so that the weight of each tray P can be accurately measured. If the arrangement gap D between the projections 16 along the conveying belt travel direction is smaller than the length L of the measuring table 52, the rear tray may not be able to exit the measuring table 52. (P) is moved to the measuring table 52 may cause interference between the two trays (P).

In addition, as shown in FIG. 5, the protruding height H of the protrusion in the conveyance belt 14 along the upward direction may be equal to or greater than the height S of the measuring table 52 extending upward from the conveying belt. That is, the protrusions 16 may be formed to protrude upward from the upper end of the measuring table 52. The degree of protrusion of the protrusion 16 relative to the side bottom 52 is sufficient to push the tray P to move. The protrusion 16 keeps protruding upward from each member in the course of passing the upward tilting member 51, the measuring table 52, and the downward tilting member 53. As a result, the projection 16 is continuously pushed up from the conveyance belt 14 and is in a non-contact state so that the protrusion 16 can continue to move in the advancing direction of the conveyance belt 14. If the projection height H of the projection 16 is lower than the upper height S of the measuring table 52, it does not touch the tray P which is spaced apart from the conveying belt 14 and placed on the measuring table 52, so that the tray ( P) cannot be moved.

Hereinafter, the operation of the weighing device 40 will be described with reference to FIG. 6.

When the sorting system is driven, products such as apples are supplied to the conveying conveyor 10 in the state contained in the tray (P). The tray P is moved to the conveyance belt 14 of the conveying conveyor 10, and is conveyed at regular intervals one by one by the projections 16 installed on the conveying belt 14. The tray P conveyed by the conveying conveyor 10 is passed through the weighing device 40, each weight is measured.

Each tray P is spaced upwardly from the conveying belt 14 while passing through the upward tilting member 51 of the weighing device 40. As the tray P passes through the upwardly tilting member 51, the protrusion 16 provided on the conveying belt 14 continues to contact the tray P, and the tray P is pushed upward by the protrusion 16. The inclined member 51 is raised. As the transfer belt 14 continues, the tray P is moved above the measuring table 52 through the upward tilting member 51. In this process, the protrusions 16 may continue to move the tray P on the measuring table 52. Thus, the tray (P) is completely lifted from the conveying belt 14 is placed on the measuring table 52.

The measuring table 52 is provided on the load cell 55, and the load of the tray P mounted on the measuring table 52 is applied to the load cell 55 via the measuring table 52. Therefore, the weight of the tray P is accurately detected through the load cell 55. Since the weight of the tray P is already set, the weight of the product directly loaded on the tray P can be detected through the detection result of the load cell 55.

As the conveying belt 14 continues to move, the tray P is moved to the downward tilting member 53 through the measuring table 52. The tray P is lowered through the downward inclination member 53 while being continuously pushed and moved by the projection 16 of the conveyance belt 14 and placed on the conveyance belt 14 again. This process is performed continuously, the weight of each product is detected as the trays P pass through the measuring table 52 continuously.

After passing through the weighing apparatus 40, the tray P is discharged and sorted by each inclined path 22 of the discharge part 20 according to the weight. Through the traveling speed of the conveyance belt 14, after passing through the weighing device 40, the transport distance and time for the tray P to reach each ramp 22 can be calculated. Thus, the tray P can be accurately discharged to the ramp 22 for each grade according to the moving distance and time of the tray P.

While the exemplary embodiments of the invention have been illustrated and described as described above, various modifications and other embodiments may be made by those skilled in the art. Such modifications and other embodiments will be considered and included in the appended claims without departing from the true spirit and scope of the invention.
