[0013]

The ginseng 1 after cleaning and sorting is sent by the conveyor 2 in a disordered state, and is delivered to the trough-shaped conveyor 3 whose conveyance direction is different by 90 degrees. Trough type conveyor 3
As the width of the conveyor at the center of the trough is narrow and the conveyors on both sides are slanted, the carrots 1
Are necessarily oriented vertically with respect to the direction of travel of the trough conveyor 3. Since there is no element in which the carrot 1 reaches the conveyor 2 and the head of the carrot 1 is biased in one direction on the conveyor 2, the carrot when it is transferred from the conveyor 2 to the trough-shaped conveyor 3 With respect to the direction of travel of the head, the head side head and the tail side head are naturally sent in a roughly half-divided state.

Since the discharge portion of the trough type conveyor 3 also forms a trough shape like the intermediate portion of the conveyor, the carrot 1 is rotated in the horizontal direction of the rotary disk device 5 through the chute 4 in the same state. The disc 6 is fed in a tangential direction on the outer periphery of the disc 6. That is, the trough type conveyor 3 is a carrot 1.
Has a function of vertically aligning with the traveling direction and discharging in that state. The outer part of the disk 6 is from the introduction part of the carrot 1.
The discharge portion at a position advanced by approximately half a turn is covered with a side wall 7 fixed to the frame 9 and a side wall 8 adjacent to the frame 7 and formed of an endless belt that is pressed by the side surface of the disk 6 and moves with the movement of the disk 6. .

On the other hand, the disk 6 is rotating in the direction in which the fed carrot 1 advances, and the fed carrot 1 is received in the longitudinal direction by the series of side walls 7 and 8 by the centrifugal force of rotation. Moves in a state. The speed of the outer peripheral portion of the disk 6 is set to such a speed that the carrots 1 do not overlap on the disk 6 and are always in one column.
With this configuration, the rotating disk device 5 is arranged such that the carrots 1 on the disk 6 are head-side heads and tail-side heads almost half-divided in the direction of travel, and in a vertical line in the direction of travel. It has the effect of becoming a uniform state. The carrots 1 pass through the chutes 10 from the discharge part of the disk 6 and are arranged in a row so that the carrots 1 and 12 are provided with skirts having narrow inner widths so that the carrots can pass vertically without resistance. It is sequentially conveyed by 13. Conveyor 1
The transport speed of 1 is set faster than the outer peripheral speed of the disk 6,
Further, the conveyors 12 and 13 are sequentially increasing in speed with respect to the conveyor 11. The purpose of this setting is to keep a sufficient space between the carrots 1 at the position of the conveyor 13 so as not to hinder the subsequent processing.

The conveyor 16 changes its traveling direction by 90 degrees with respect to the conveyor 13, and has the function of always receiving the carrots 1 one by one between the crosspieces 17 and transporting them to the box packing position.
The position of the discharge part of the conveyor 13 is configured so as to coincide with the storage part of the carrot 1 partitioned by the crosspieces 17 fixed on the belt of the conveyor 16 when the conveyor 16 is stopped. Is transferred to the conveyor 16. At this time, the sensor 20 detects the carrot 1, the conveyor 16 is driven, and the conveyor 16 is conveyed in the filling direction. When the sensor 21 for detecting the crosspiece 17 detects the next crosspiece 17, the conveyor 16 conveys the signal. Stops. Conveyor 13
1 provided between the discharge part of the conveyor and the conveyor 16
4 is lowered when the accommodating portion of the conveyor 16 is empty, and the carrot 1 is transferred from the conveyor 13 to the conveyor 16, but at this time, the conveyor 16 moves by one pitch of the crosspiece 17, so during this movement The signal from the sensor 20 prevents the carrot 1 from entering the conveyor 16
Is arranged so as to prevent the carrot 1 from entering, and when the conveyer 16 is stopped next time, the signal from the sensor 21 causes the stopper 14 to move down and the next carrot 1 to be fed to the conveyor 16.

With this structure, the carrots 1 are conveyed while being surely housed one by one between the bars 17 of the conveyor 16. The leading end of the conveyor 16 is bent downward by 90 degrees, and the carrot 1 is conveyed directly downward and discharged at that portion. The carrying surface of the part for carrying the carrot 1 in the directly downward direction is provided with a pressing plate 18, and is configured so that the tension spring 19 gently presses the carrying surface. The holding plate 18 has the function of preventing the carrot 1 from deviating from the crosspiece 17, and prevents the carrot 1 from falling obliquely downward when the carrot 1 is discharged at the lower end of the carrot 1 so that the carrot 1 may fall directly downward. It also has an inducing action. Further, since the tip of the crosspiece 17 tends to bend downward due to the weight of the carrot 1 in the portion conveyed immediately below, the crosspiece 17 is slightly inclined in the direction opposite to the traveling direction of the belt with respect to the conveyor belt. It has been configured.

As described above, the carrot 1 is discharged from the lower end of the conveying section directly below the conveyor 16 in the direction directly below, and is filled in the cardboard box 24. The cardboard boxes 24 are supplied by the conveyor 41, and at the position of the operation conveyor 30, the cylinders 241 press the cardboard boxes 241 onto the operation conveyor 30, and the motor rollers 31 drive them to move forward.
It stops by hitting the first one of the stoppers 32 arranged in parallel. The rod of the cylinder 42 is located at the position where the cardboard box 24 is pushed down, and the switch 4 mounted on the cylinder 42
When 4 is operated, it is retracted to its original position and is in a standby state. At the same time as the cardboard box 24 hits the first stopper 32, the sensor 34 detects the arrival of the cardboard box 24, the cylinder 37 is activated, and its rod is lifted by a lift 36.
Is pushed up to the filling work position of the cardboard box 24. At this time, the partition frame 22 is located at a position corresponding to the cardboard box 24 coming up from the bottom, and the cardboard box 24 is fitted into the partition frame 22. The position of the partition frame 22 at this time is the conveyor 1
It is set so that the position of the carrot 1 falling from the discharge part 6 and the position of the endmost filling section partitioned by the partition plate 23 of the partition frame 22 are aligned.

When the lift table 36 is fully raised to a predetermined position, the switch 46 of the cylinder 37 is actuated to move the conveyor 16
The transportation of all the equipment up to is started, and the filling of carrot 1 is started. Ginseng 1 is a cardboard box 2 in a narrow partition
From the bottom of 4, the direction of the head and the direction of the tip of the tail are approximately half and opposite, and the particles are sequentially filled upward in parallel, and the filling weight is the predetermined total filling weight divided by the number of partition sections. When the weight reaches the predetermined weight, that is, the predetermined filling weight per one section, the first stopper 32 is lowered by the signal from the load cell 35, the cardboard box 24 moves on the operation conveyor 30 and stops by hitting the next stopper 32. Then, the carrot 1 is filled in the next compartment. At this time, since the partition frame 22 fitted in the cardboard box 24 is slidably supported by the shaft 29, it moves together with the cardboard box 24.

This operation is sequentially and automatically performed for each compartment, and when the filling of the last compartment is completed, the load cell 3
The signal from 5 causes the last stopper 32 to remain raised and to stop all devices carrying the carrot 1, including the conveyor 16, and lower the rod of the cylinder 37. That is, the corrugated cardboard box 24 filled with the carrot 1 descends while being separated from the partition plate 23 and the partition frame 22, but the carrot 1 is naturally moved and filled in the gap where the partition plate was present. The carrots 1 are stored in the cardboard boxes 24 in an average and even manner. When the lowering is completed, the last stopper 32 is lowered by the signal from the switch 47 installed in the cylinder 37, and the restraint on the corrugated cardboard box 24 is released. It is delivered to and sent out from the conveyor 43 that is connected to this.

At the same time, the signal from the switch 47 raises the stopper 32 to restore the original state, and the cylinder 48 pushes the partition frame 22 to return it to the initial position. The rod of 48 returns to the original position and enters the standby state. In this state,
The next cardboard box 24 is again supplied to the operation conveyor 30 by the cylinder 42, and the same operation is repeated. When the carrot 1 to be boxed is no longer on the conveyor 16, the functions of the sensors 20 and 21 are stopped, and the conveyor 16 is driven by a separate switch to complete the work.

The position of the partition frame 22 at this time is the conveyor 1
It is set so that the position of the carrot 1 falling from the discharging section 6 and the position of the endmost section of the filling section partitioned by the partition plate 23 of the partition frame 22 coincide with each other.

When the lift table 36 is fully raised to a predetermined position, the switch 46 of the cylinder 37 is actuated to start driving all the conveyors up to the conveyor 16 and the filling of the carrot 1 into the cardboard box 24 is started. It In the carrot 1, the head side and the caudal side of the carrot box 24 are reversed in a half direction from the bottom of the corrugated cardboard box 24 in the endmost partition among the plurality of narrow partitions partitioned by the partition plate 23. In this state, they are stacked in parallel and upward, and when the filling weight reaches the set weight per division, the signal from the load cell 35 lowers the first stopper 32 and the cardboard box 2
4 is the operation conveyor 3 because the constraint at that position is released.
0, and hit the next stopper 32 to stop,
Carrot 1 is filled into the next compartment. At this time, since the partition frame 22 fitted in the cardboard box 24 is slidably supported by the shaft 29 via the bearing 25, it moves together with the cardboard box 24. This operation is automatically performed sequentially for each compartment, and when the filling into the last compartment is completed,
The last stopper 3 by the signal from the load cell 35
2 is raised, that is, with the cardboard box 24 held in that position, all the devices that convey the carrot 1, including the conveyor 16, are stopped and the rod of the cylinder 37 is lowered. That is, the elevator 36 is lowered.

At this time, a cardboard box 2 filled with carrot 1
4 also descends while being separated from the partition plate 23 and the partition frame 22, but the carrot 1 is naturally moved and filled in the space where the partition plate 23 was present, so that the carrot box 24 is filled with the carrot 1. They are stored on average and in an orderly manner. When the lowering of the platform 36 is completed, a signal from a switch 47 installed in the cylinder 37 lowers the last stopper 32 to release the restraint on the cardboard box 24, so that the cardboard box 24 is moved and operated. From the conveyor 30, it is delivered to the conveyor 43 connected to the conveyor 30 and sent out. On the other hand, at the same time, the signal from the switch 47 causes the stopper 32 to be fully raised and returned to its original state, and the cylinder 48 pushes the partition frame 22 to return it to the initial position. The rod of 48 contracts and returns to its original position, and enters the standby state. This completes the carrot 1 filling work into one of the corrugated boxes 24. In this state, again by the cylinder 42,
The next empty cardboard box 24 is fed to the operation conveyor 30 and the same operation is repeated. When the carrot 1 to be packed is no longer on the conveyor 16, the sensor 2
The functions of 0 and 21 are stopped, the conveyor 16 is driven by a separate switch, the carrot 1 is discharged, and the work is completed.

Since the present invention is configured as described above, it has the following effects. The carrot 1 conveyed in a messy state by the conveyor 2 is transferred to the trough-shaped conveyor 3 so that it is oriented vertically with respect to the conveying direction, and the head side head and the tail side head are It is conveyed in a roughly half-spread state and sent out to the rotating disk device 5 via the chute 4, but the trough-shaped conveyor 3 also has a trough-shaped discharge part, so the arrangement of the carrots 1 is not disturbed. Is discharged. The rotating disk device 5 has an effect of surely separating the supplied carrots 1 one by one. That is, the carrots 1 supplied from the trough-shaped conveyor 3 may be discharged in an overlapped state depending on the supply amount thereof. Therefore, if the carrots 1 remain in this state, the next process will be hindered. On the outer periphery, set the rotation speed so that one carrot and one carrot will always be in one column.

The outer peripheral portion of the disk 6 is provided on the introduction portion of the carrot 1 and is fixed to the frame 9, and the side wall 8 is connected to the side wall 7 and extends to the discharge portion and moves with the outer periphery of the disk 6. Carrot 1 is a disc 6 because it is covered by
Due to the centrifugal force of the rotation of (1), while being received by the side walls 7 and 8, it is moved forward in a single column in a vertical state, and is discharged from the discharge section provided at a position about half a rotation from the introduction section. As described above, the side wall 8 moves together with the outer circumference of the disk 6, so that the carrot 1
Since there is no relative movement in the part of the side wall 8 and therefore there is no resistance to the carrot 1, it can be transported smoothly, and at the same time, it has the effect of protecting the carrot 1 from scratches. Granted. The cylindrical enclosure 73 provided at the center of the disk 6 has an effect of guiding the carrot 1 toward the side wall 7 when the carrot 1 is supplied in an overlapping manner. The guide plate 83 has an effect of guiding the carrot 1 to be surely discharged into the chute 10 at the discharging portion.

For the above reasons, in the discharge part of the rotary disk device 6, the carrot 1 has a head-side head and a tail-side head which are distributed approximately half and half. On the other hand, the effect of arranging them in a vertical line is obtained, and the condition for performing the subsequent work is satisfied. Conveyors 11, 12 and 13 connected from chute 10 each have one
The carrot 1 has a pair of skirts vertically narrowed in the direction of travel and having an inner width narrow enough to pass without resistance, and is set so as to be faster than the outer peripheral speed of the disk 6 and to be gradually increased in speed from the conveyor 11. There is. With this configuration, the carrot 1 has an effect that the carrots 1 are not laid sideways in the conveyors 11, 12 and 13 with respect to the traveling direction, and on the conveyor 13, the carrots 1 are sufficiently spaced from each other. . The conveyor 16 receives the carrot 1 from the conveyor 13 and conveys the carrot 1 to the position of the corrugated cardboard box 24, and the conveying direction is arranged at a 90 degree difference from the conveyor 13.

The carrots 1 are supplied to the conveyor 16 one by one from the conveyor 13, and the carrots are fed in every time the carrots are supplied, and the carrot boxes 24 are filled with the carrots 1. Carrot 1 is conveyor 1
Although one by one is sent to the storage section partitioned by the crossbar 17 of 6, the sensor 20 detects that one carrot 1 has been supplied and conveys the conveyor 16 by one partition.
The sensor 21 for detecting the next carriage detects the next crosspiece 17, stops the conveyance of the conveyor 16, and waits for the next supply of the carrot 1.
While the conveyor 16 is stopped, the stopper 14 is lowered, and the carrot 1 can be supplied to the conveyor 16. However, when the conveyor 16 is being conveyed, the stopper 14 goes up due to a signal from the sensor 21, and The discharge part is closed to prevent the carrot 1 from entering the conveyor 16. When the conveyor 16 conveys by one pitch of the crosspiece 17 and is stopped, the signal from the sensor 21 causes the stopper 14 to move down, and the carrot 1 can be supplied to the conveyor 16 again.

With this structure, the carrots 1 are surely supplied one by one to the storage section partitioned by the crosspieces 17 of the conveyor 16. As described above, the carrots 1 are conveyed to the conveyor 13 in a vertical direction in a row in which the head-side heads and the tail-side heads are distributed in approximately half and half. When the ginseng 1 is supplied on top of 16, the heads of the carrots 1 are distributed in an alternating manner, and the carrots 1 are conveyed one by one between the crosspieces 17. At the end of the conveyor 16 at the destination, the frame 77 is bent 90 degrees downward, and the frame 77 is conveyed immediately below and discharged. The pressing plate 18 is gently pressed by the tension spring 19 on the conveying surface of the conveying unit in the immediately downward direction. With this configuration, since the position at which the carrot 1 is discharged can be lowered to the limit with respect to the cardboard box 24 that receives the carrot 1 on the lower side, the head can be suppressed to a minimum and the carrot 1 at the time of falling can be reduced. In addition to preventing damage, the presser plate 18 prevents the carrot 1 from deviating,
At the lower end portion, the carrot 1 is prevented from being discharged in an oblique direction and guided so as to be discharged directly below, so that it has an effect of dropping it to a stable position.

Next, the above effect is obtained in the case of a horizontal conveyor, that is, the construction of other parts is the same as that of the conveyor 16,
This will be described in comparison with the case of a conveyor that does not have a conveying section in the directly downward direction. When the carrot 1 is discharged from the end of the horizontal conveyor and stored in the cardboard box 24 placed below, the lower end of the bar 17 on the return side of the conveyor does not hit the upper end of the lid of the cardboard box 24. You have to put the conveyor in. Therefore, the height of the central portion of the carrot 1 with respect to the cardboard box 24 is such that the height of the crosspiece 17 on the return side, the outer diameter of the conveyor head pulley, the thickness of two conveyor belts, and the maximum outside of the carrot 1. Only the size of half the diameter added,
Minimum required. Further, the position where the carrot 1 is discharged is a portion where the crosspiece 17 turns downward in the head pulley portion, that is, at this position, the speed of the crosspiece 17 becomes faster than the conveying speed, so the carrot 1 is stored in the cardboard box 24. With a big head,
Moreover, it is thrown diagonally downward with a large initial velocity.

In this case, since the head drop is large, the amount of increase in speed due to the free fall acceleration is also large at the position received in the cardboard box 24. As a result, there is a high possibility that the carrot 1 will be damaged, and at the same time, the state of filling the carton box 24 will be disordered. On the other hand, in the conveyor 16 according to the present invention, since the conveyor 16 and the discharge portion are provided in the direct downward direction and the conveying surface is guided by the pressing plate 18, the crosspiece 17 is provided on the upper end of the lid of the corrugated cardboard box 24. The carrot 1 can be brought close enough to avoid hitting it, and the drop is minimized, and the initial speed of the carrot 1 at the time of discharge is only the transfer speed of the conveyor 16, which depends on the acceleration of free fall at the position received in the cardboard box 24. The amount of increase in speed can be suppressed to a small value because the head difference is small, and the impact on the carrot 1 can be minimized. Moreover, the holding plate 18
By the effect of, the carrot 1 is guided in a direct downward direction, so that the carrot 1 is filled in a predetermined position and is stored in an orderly state. In addition, the crosspiece 17 has a carrot
Due to the weight of the
To prevent it from becoming
It is configured to be inclined by the angle of.

Next, effects related to the operation of the cardboard box 24 for filling the carrot 1 will be described. The empty cardboard box 24A is supplied by the conveyor 41, and one of the cardboard boxes 24 is pushed out onto the operation conveyor 30 by the cylinder 42 at a position corresponding to the operation conveyor 30 and driven by the motor roller 31 to move in the traveling direction. It stops by hitting the first one of the stoppers 32 arranged in parallel toward each other. At that time, when the sensor 34 detects the arrival of the cardboard box 24, the cylinder 37 is actuated, and the rod thereof causes the load cell 35, the operation conveyor 30, and the lift table 36 on which the cardboard box 24 sent thereon is placed. Push up.

At this time, since the partition frame 22 is located at a position corresponding to the rising cardboard box 24, the cardboard box 24
Are sequentially fitted into the partition frame 22 from the upper lid portion. Each side surface of the partition frame 22 and both end surfaces of the partition plate 23 fixed to the lower part of the partition frame 22 are configured so that the lower side is narrowed in a tapered shape to facilitate the fitting of the cardboard box 24, while the partition frame is provided. The upper part of 22 is formed in a tapered shape that widens upward, and has an effect of smoothly receiving the carrot 1 supplied from above. When the cardboard box 24 is fitted into the partition frame 22 to a predetermined position, the upright part of the lid of the cardboard box 24 is guided by the taper part of the upper part of the partition frame 22 and obliquely opens outward to escape. The distance of the cardboard box 24 to the discharge part of the conveyor 16 above it can be shortened to the utmost, that is, the effect of minimizing the head of the carrot 1 is given.

When the cardboard box 24 is raised to a predetermined position, a signal from the switch 46 of the cylinder 37 drives all the conveyors up to the conveyor 16 to start the filling of the carrot 1 into the cardboard box 24. Carrot 1
In the partition at the end of the narrow partition section divided by the partition plate 23, the heads are filled alternately in parallel in an upwardly distributed state. When the carrot 1 reaches a predetermined weight for one section, the first stopper 32 is lowered by the signal from the load cell 35, and the corrugated cardboard box 24 is transported and the next one installed according to the mounting interval of the partition plate 23. It stops by hitting the stopper 32, and filling into the next partition section is performed. When the cardboard box 24 moves, the partition frame 22 fitted therein also moves along with the cardboard box 24 because the upper part thereof is slidably supported by the shaft 29 via the bearing 25. By partitioning the inside of the cardboard box 24 narrowly by the partition plate 23, when the carrot 1 falls into the cardboard box 24, the carrot 1 is prevented from dancing and the orientation of the carrot 1 is disturbed, and the carrots 1 are packed in parallel in an orderly manner. Is given.

The filling work of the carrot 1 is sequentially performed from the end section as described above, and when the filling of all the sections is completed,
By the signal from the load cell 35, all the transportation devices up to the conveyor 16 are stopped, and the cardboard box 24 is lowered while being held by the last stopper 32.
The signal from the switch 47 causes the final stopper 32
When the cardboard box 24 is lowered, the cardboard box 24 is conveyed on the operation conveyor 30, is transferred to the conveyor 43, is sent out, and all the stoppers 32 are raised to return to the original state, and the cylinder 48 pushes the partition frame 22 to return to the original position. Return to. When the cardboard box 24 descends, the partition plate 23 is attached to the cardboard box 24.
The carrot 1 will naturally move and fill the void. Since the partition plate 23 is extremely thin, the arrangement of the carrots 1 will not be disturbed. The above is the description of the procedure and effect of filling the carrot 1 into one cardboard box 24, and the operation can be repeated to continue the work. With the above-mentioned series of devices, it is possible to perform the packing work of the carrots 1 and the alignment work of the carrots 1 which is indispensable as a pretreatment thereof without manpower. The automation of the boxing work makes a great contribution to the processing work of the carrot 1.
