In this state, the tilting arm 703 is held upright with respect to the substrate 701. When the piston rod 711a is contracted from this state, the tilting arm 703 tilts rearward in the direction of arrow C about the rotation shaft 702d.

  A rotating lever 702f is fixed to the other end of the rotating shaft 702d along with the lower sprocket 702e described above. At the rear end of the substrate 701, the piston rod 712a of the table rotating cylinder device 712 attached to the other end in the width direction is connected to the rotating lever 702f.

  Between the upper sprocket 703e and the lower sprocket 702e, two intermediate sprockets 703g rotating integrally are attached to the tilting arm 703, and an endless chain 712b is hung between the upper sprocket 703e and one intermediate sprocket 703g. The endless chain 712b is similarly hung between the lower sprocket 702e and the other intermediate sprocket 703g. When the rotating lever 702f is rotated in the direction of arrow E in FIG. And the lower sprocket 702e also rotates in the same direction. Then, the upper sprocket 703e rotates in the same direction through the two endless chains 712b and the two intermediate sprockets 703g that rotate integrally, the table support shaft 703d rotates, and the product box mounting table 704 moves in the direction of arrow G. Tilt.

  When the product box mounting table 704 is tilted in the direction of arrow G, the product box 1 held by the holding mechanism 709 on the second transport conveyor 2b, which is the product box mounting table of the product box mounting table 704, is the product box. Although the opening is directed upward in the exchange position, the opening is lifted so that the opening is gradually directed forward. At that time, the tilting arm 703 also tilts in the direction of arrow C in synchronization with the rotation of the product box mounting table 704 and stops at the agricultural product supply start position indicated by the two-dot chain line in FIG. At this agricultural product supply start position, the empty product box 1 rotates to an inclined angle close to 90 degrees from the product box replacement position, and the supply conveyor 110 rotates in the direction of arrow A to continuously feed the carrots V as agricultural products. The supply end of the supply conveyor 110 enters the product box 1 in the large supply unit 110b to be supplied.

  Then, the tilting arm 703 is also tilted in the direction of arrow D while tilting the product box mounting table 704 in the direction of arrow H from this agricultural product supply start position. At that time, the supply end in the large supply section 110b of the supply conveyor 110 and the drop position in the product box 1 of the carrot V which is the agricultural product falling from the supply end are the front side of the product box (as in the above case) The product box conveying device 2 gradually moves backward from the downstream side in the conveying direction to the front side and the upstream side to the rear side. This operation will be described below with reference to FIGS.

  FIG. 7A shows a state in which the empty product box 1 with the flap 1a opened is transferred from the first transport conveyor 2a of the product box transport device 2 to the second transport conveyor 2b, and the tilt arm of the product box tilting device 7 is shown. Reference numeral 703 stands substantially upright, and the product box mounting table 704 is in a standby state in which the second transport conveyor 2b is maintained at a horizontal position that coincides with the transport surface of the product box transport device 2. The hook portion 708 c of the stopper driving device 708 stops at the uppermost position and allows the stopper rod 705 to protrude by the spring force of the spring 707. Further, the holding pressure release device 709 is in a holding pressure release state in which the movable box press pad 709a is positioned at one end in the width direction until the empty product box 1 is transferred to the second conveyor 2b. After confirming that the empty product box 1 is in contact with the stopper rod 705 and stopped at a predetermined position of the second conveyor 2b (for example, it is detected by detecting that the product box detection sensor has been transferred to the second conveyor 2b. After a lapse of time), the rod of the air cylinder device 710a is contracted so that the movable presser pad 709a is brought into contact with the side surface of the product box 1 by the spring force of the spring 709h, and the pair of presser pads 709a and 709b sandwich the product box 1 Holding is performed to prevent the product box 1 from being displaced from the second transport conveyor 2b during rotation described later. When this product box replacement operation is completed, a product box mounting table lift operation is started by a product box tilt control device (not shown) to pack carrots V as agricultural products in the product box 1. The operation procedure of the product box tilt control device is performed according to the timing chart shown in FIG. 8, and each product box mounting table lift operation is performed based on the measured value measured by the weighing machine 3. In addition, about the measured value which performs a product box mounting base lift operation | movement, it can set arbitrarily.

  In the product box mounting table lift operation, first, the table rotating cylinder device 712 is driven so that the product box mounting table 704 rotates to half the angle until the product box mounting table 704 reaches the ginseng input position. When the product box mounting table 704 is moved to this half angle, a reset time for resetting the weighing machine 3 is awaited. The tilt arm 703 stops at the product box replacement position until the reset time, and when the reset time has elapsed, as shown in FIG. 7B, the tilt arm 703 and the product box mounting table 704 are synchronized to a predetermined loading position. Tilt. The position at which the weighing machine is reset is in a state where the product box 1 has entered the large-out portion 110b of the supply conveyor 110, and if the product box mounting table 704 is tilted as it is, it will collide with the large-out portion 110b. From here, the tilting arm 703 is tilted to tilt the product box 1 in the upright direction while keeping the product box 1 away from the conveyance end of the large-out portion 110b, and the large-out portion is placed on the front wall of the product box 1 at the bottom position. The conveyance end of 110b approaches. This position is defined as the first input position.

  When the product box mounting table 704 arrives at the first input position, a large-out process is started in which the supply conveyor 110 is driven to rotate forward and the carrot V is input into the product box 1 from the large-out portion 110b. At that time, the carrots V are put into the product box 1 with the length direction aligned in the width direction. The carrot V that is put into the product box 1 at the first putting position is dropped onto the front wall of the product box 1. Since the carrot V input in the first input process is accumulated from the front wall surface to the bottom surface of the product box 1, when the carrot V having a predetermined weight is input, as shown in FIG. Only the pedestal 704 is rotated in the down operation direction opposite to the above-described lift operation direction by an angle of about a quarter of the total rotation angle (hereinafter referred to as the down rotation angle) and stopped (this stop position). Is hereinafter referred to as a second position for input). Although the product box mounting table 704 is rotated to the charging second start position, the tilting arm is still maintained at the tilting position at the charging first position.

  As the product box mounting table 704 is rotated from the first input position to the second input position, the carrot V in the product box 1 is adjusted to a V-shaped corner formed by the front wall and the bottom surface. The volume of the product box 1 which moves and exists below the conveyance end of the large-out portion 110b increases.

  When a predetermined weight of ginseng V is introduced from the large projecting portion 110b at the second charging position, as shown in FIG. 7D, the tilt arm 703 is moved to a predetermined tilt angle (from the charging start position to the above-described product box replacement position). The product box mounting table 704 is generally moved toward the downstream side in the transport direction by tilting in the plus direction by about one third of the total tilting angle), and the product box mounting table 704 is moved by the down rotation angle. Rotate to stop (this stop position will be referred to as the third position for input hereinafter).

  When the product box mounting table 704 rotates from the second loading position to the third loading position, the product box 1 held on the product box mounting table 704 is entirely downstream in the transport direction of the product box transporting device 2. The carrot V that moves and falls from the conveyance end of the large-out portion 110 b moves to the rear side of the product box 1. Then, at the third input position, the carrot V is newly input in an area where there is little existing carrot V, and the height of the input carrot V can be flattened without being biased. it can. Then, as shown in FIG. 7 (e), when the product box mounting table 704 is tilted from the third input position to the fourth input position, the carrots V in the product box 1 are generally leveled and raised. Are averaged.

  The product box mounting table 704 is rotated from the third input position by the down rotation angle, and the tilt arm 703 is further tilted in the plus direction by a predetermined tilt angle. Then, the product box mounting table 704 moves further downstream in the transport direction of the product box transport device 2 as a whole, and the carrot dropping position falling into the product box 1 from the supply end of the large-out portion 110b is the product box 1 It approaches the rear wall of the product box 1 and is put into an area where the carrot V already put in the product box 1 is small. By rotating the product box mounting table 704 while tilting and moving the product box as a whole from the first input position to the fourth input position, the carrots are inserted into the product box 1 at each position, so The input position of V can be shifted from the front wall to the rear wall of the product box 1, and when the product box 1 is gradually rotated to the horizontal position, the packaging height of the carrot V is leveled. It can be flattened.

  The tilting arm 703 returns to the original product box replacement position in the charging fourth position, and when the weighing machine 3 detects that the previous weight has been reached by charging the carrot V in the charging fourth position, the supply conveyor 110 is driven. It stops, and the supply of the carrot V from the large-out part 110b is stopped.

  When the preset processing time at the fourth input position (the time during which the weighing machine 3 can stably measure the weight) is completed, the product box mounting table 704 is rotated to the original product box replacement position. Let the carrots V pack up.

  The product box 1 in which the carrot V is charged up to the previous weight and returned to the product box replacement position is transferred to the third transport conveyor 2c and is supplied with the carrot V from the dispensing unit 110c. The mechanism 709 drives the air cylinder device 710a for releasing the clamping of the product box 1 held on the second conveyor 2b by the mechanism 709, extends the piston rod 710b, and moves the movable rod 709f to the spring 709h. The movable box presser pad 709a is moved away from the side of the product box 1 against the spring force.

  The product box 1 is released from the holding pressure, and the stopper driving device 708 is driven to move the hook portion 708c downward so that the stopper rod 705 is immersed below the conveying surface. As shown, the product box 1 on the second transport conveyor 2b can be transported to the third transport conveyor 2c. At this time, the second stopper 2e provided on the third transport conveyor 2c is in a state of protruding upward from the transport surface, and the product box 1 sent from the second transport conveyor 2b to the third transport conveyor 2c is the second stopper. By 2e, the conveyance is immediately stopped and the dispensing box 5 stops.

  In the dispensing boxing unit 5, the conveyance end of the dispensing unit 110c of the supply conveyor 110 is positioned directly above the product box 1 stopped by the second stopper 2e, and the driving direction of the supply conveyor 110 is switched to the reverse direction. This switching timing can be switched, for example, after a predetermined timer time elapses after the rotation in the forward direction is stopped.

  In the case of supplying carrots V in large scale, even if the supply of carrots V is stopped at the last weight, the same previous weight is not always supplied into the product box 1, and the remaining weight is also converted into the number of carrots, for example. Therefore, the number of carrots V corresponding to the remaining weight actually obtained from the weight immediately before measurement is calculated. Then, the number of carrots V calculated from the conveyance end of the dispensing unit 710c of the supply conveyor 110 are dropped and supplied to the product box 1 to perform boxing.

  When boxing in the dispensing boxing unit 5 is completed, the second stopper 2e is released, and the product box 1 packed with carrot V having a predetermined weight is moved toward the transfer end of the third transfer conveyor 2c.

  The product conveyance conveyor 8 is arrange | positioned at the conveyance termination of the 3rd conveyance conveyor 2c, and the product box 1 in which the box of the carrot V is packed is supplied to this product conveyance conveyor 8 from each 3rd conveyance conveyor 2c.

  In the present embodiment, the switching from the first loading position to the fourth loading position and the end of the fourth loading position are performed based on the measured values, but the switching may be performed based on the loading time. .

  The supply conveyor 110 is fixed to a fixed frame member (not shown) arranged on one side or both sides of the supply conveyor 110 and protrudes so that the large protruding portion 110b can cover the product box 1. 110 and the fixed frame member are connected to each other via a linear movement mechanism, and when the carrot is outfed and supplied, the linear movement mechanism is moved to the large portion 110b side, so that the carrot V is dropped relative to the product box 1. It becomes possible to change. In this case, the carrot V can be dropped directly to the vicinity of the rear wall of the product box 1 which cannot be reached only by the rotation of the product box mounting table 704 and the tilting arm 703.

  In addition, by moving the linear movement mechanism back and forth, the carrot V can be dropped from the product box 1 between the front wall and the rear wall of the product box 1. The thickness can be made even more uniform.

  Further, in the present embodiment, the product box 1 is placed on the product box mounting table 704 by driving the supply conveyor 110 in one direction, increasing the supply speed at the time of large delivery, and slowing the supply speed at the time of small delivery. In this state, the number of carrots V corresponding to the remaining weight can be charged. However, considering efficient carrot packaging, the product box mounting table 704 can be turned off by the end of the large-out as in this embodiment. If the product box 1 is discharged, the next empty product box 1 is placed on the product box mounting table 704, and the above-described lift operation is executed, the carrot can be input from the dispensing portion 110c of the supply conveyor 110 during that time. The ginseng can be thrown out immediately after the lift operation is completed. Therefore, the time for the lift operation can be shortened, and the processing capacity is increased accordingly.

  Further, in order to accurately measure the measured value, the supply speed of the large-out conveyor can be changed based on the measured value. Accordingly, by changing (slowing) the supply speed of the impact that occurs when dropping when continuously supplied, the impact at the time of dropping can be suppressed, and the measurement value of the weighing machine can be prevented from becoming unstable.

Second Embodiment FIGS. 9 and 10 show a second embodiment of the present invention.

  The present embodiment illustrates a case where the supply direction of the supply conveyor 2 is orthogonal to the conveyance direction of the product box conveyance device 2 that conveys the product box 1.

  As shown in FIG. 10, the product box transport device 2 includes a first transport conveyor 2 a that transports an empty product box 1, a second transport conveyor 2 b that forms a product box mounting table of the product box mounting table 704, 2 A third transport conveyor 2c to which a product box 1 in which carrots V are boxed in the weight immediately before the transport conveyor 2b is sent out is arranged in a straight line, and the first transport conveyor 2a and the third transport conveyor 2c The configuration in which the weighing machine 3 is arranged between them and the product box tilting device 7 is mounted thereon is the same as in the first embodiment.
