Abstract

PURPOSE:To wash small turnips without direct contact with water by providing means for transferring the small turnips and means for measuring the outside diameters in the root parts of the small turnips under transfer. CONSTITUTION:The small turnips are placed by each piece onto attachments 4 from a supplying section 1A. The pawl attachment mounted to an endless roller chain is inclined by a pawl attachment inclining bar 6B when the attachment comes to the supplying section. The rear end 4D1 of a lower pawl 4D comes into contact with a pawl opening guide bar 6A, by which the lower pawl is opened. The small turnips enter a draining chamber where water drops are removed. The small turnips are thereafter introduced into a sensor box section 8. Contact plates 8E2, 8F2 in the sensor box section 8 open by tracing the outside diameter of the small turnips upon entry of the small turnips. A tuning gear rotates to rotate a pinion 8G which in turn rotates a slit plate 8H to measure the diameter of the small turnips and to classify the small turnips. Thus, the small turnips are classified by standards.

In the figure, 4E is a shaft that supports these claws, 4F is a torsion coil spring for causing both claws to act inwardly, and 4G is a projection that restricts openings of the upper claw 4C and the lower claw 4D beyond a certain level.

Therefore, when the horizontal portion of the bracket 4B is pushed from below, it will be bent upward about the hinge 4A.

5 is a proximity detection plate disposed between adjacent claw attachments 4 in the roller chain 2C.

Therefore, an opening 2D11 is opened in the front wall 2DI of the case 2D in the left-right direction so that the claw attachment 4 that moves as the roller chain 2C moves from left to right is exposed.

Reference numeral 6 denotes a bracket for a claw-opening guide bar provided in the opening 2D11 at a portion slightly to the right of the center in the elongated direction, and a claw-opening guide bar 6A is stretched from the left to the right at the lower end of this bracket. has been done.

Reference numeral 6B denotes a claw attachment inclined bar stretched in the left-right direction on the back side of the claw opening guide bar 6A, and the claw attachment moved by this inclined bar is inclined diagonally upward.

In this state, the leaf 7A of the small fever 7 is held down between the upper claw 4C on the left and the lower claw 4D on the right.

Claw opening guide bar 6A and claw attachment inclined bar 6B
The installation location becomes the supply section LA.

Here, the effects of each of the above configurations will be explained.

The operator places small pieces of heat one by one on the claw attachment 4 from the supply section IA.

That is, the claw attachment attached to the endless roller chain is tilted by the claw attachment inclination bar 6B when it comes to the supply section, and furthermore, the rear end 4D1 of the lower claw 4D contacts the claw opening guide bar 6A. It will open with.

As a result, a small amount of heat can be easily supplied.

Once past the supply section, the claws disengage from each guide and pinch the neck of the small heat to prevent it from falling off in the draining chamber where the water droplets are blown away by the cleaning and wind.

After feeding, the plants go into the washing room and wash off the soil attached to the roots, necks, and leaves.

Cleaning method: Removal is carried out using an appropriate combination of commercially available pumps and nozzles.

Next, in the draining room, excess water droplets are blown away using a commercially available turbo blower.

Reference numeral 8 denotes a sensor box part provided in the left part of the case 2D, which measures the outer diameter of the root part 7B of the small heat 7 and delivers it to the subsequent delivery part 9 for each standard.

Therefore, the configuration of the sensor box section 8 is as follows.

A ring bracket 8A is installed above the roller chain 2C in a direction perpendicular to the longitudinal direction of the roller chain, and a pair of parallel links 8B are pivotally connected to the ring bracket 8A horizontally in the direction of movement of the roller chain 2C. 8C, one sensor plate 8D pivoted to the tips of the parallel links 8B and 8C, and a pair of synchronized gears 8E connected to the left and right corners of the sensor plate 8D via gear shafts 8E1 and 8F1. 8F and gear shaft 8
A pair of contact plates 8E2°8F2 are fixed to the lower ends of E1 and 8F1 so as to act inwardly to each other, and a pair of tuning gears 8

It is composed of an appropriate number of photomicro switches 8■ arranged around the outer periphery of the 8H.

8F21 is a tension spring for the contact plates 8E2 and 8F2 to act in the center direction, and 8J is a sensor style "non" that receives the photomicro switch 8.

8 is the casing.

Therefore, the operating state of the sensor box section 8 will be explained.

The contact plates 8E2, 8F2 are normally closed by the drawstring respring 8F21, but when the small heat enters the position shown in the figure, the contact plates 8E2, 8F2 open by following the outer diameter of the small heat, and the synchronizing gear rotates, turns the pinion 8G, and turns the slit plate 8H.

Photomicro switch 8I with multiple slit plates 8H
If you cut off which number of them, the standard based on the diameter of the small fever is "large" r3L, J , r2LJ , rLJ , rMJrSJ
, rssJ.

In this case, the parallel links 8B and 8C are designed to move the contact plates 8E2 and 8F2 in parallel so as to always catch the center of the small heat, since there may be cases where the small heat does not advance in a straight line. .

Reference numeral 9 denotes a delivery section provided at a position to the left of the supply section IA on the front wall 2D1 of the case 2D, where the pick-up rail lO1 feed vane 11. It consists of a hanger yard 12.

The delivery section 9 is arranged independently to correspond to the small fevers of "large J, r3LJ, r2LJ, rLJ, rMJ, rSJ, rS, SJ" determined by the sensor box section 8.

Pick up rail 10 is roller chain 2C from case 2D.
a horizontal plate-shaped cylinder bracket IOA projecting forward in a direction perpendicular to the direction of movement; an air cylinder 10B for driving the pick-up rail that acts on the lower surface of this bracket 10A in the front-rear direction;
It consists of a metal fitting 10C which is connected to the tip of the metal fitting 10C and has a substantially downward C-shaped front face, and a pick-up rail body lOD which is connected to this metal fitting 10C horizontally in the direction of the roller chino 2C, and further,
This pick-up rail body 10D is composed of a single rail 10Dl on the left and a single rail 10D2 on the right. The tip of the single right rail is bent into a hook shape, and the small heat 7 is conveyed while being held by a claw attachment. It is configured so that the neck can be locked and guided into the pick-up rail body 10D.

The timing of the exit and return of the pick-up rail 10 is determined by the proximity detection plate 5 and a proximity switch 13 disposed at a position to the left of the pick-up rail 10.

In this case, the double-opening of the claw attachment 4 is effective during delivery.

The sending vane 11 is for feeding the small heat on the pick-up rail body 10D to the round belt of the hanger yard 12, and is protruded horizontally from the lower end of the shaft 11A hanging on the side of the pick-up rail body 10D. The shaft 11A is configured to be driven by a timing belt IID from a sprocket IIC that meshes with a roller chain 2C according to each standard.

Therefore, regardless of the speed and extension of the roller chain, the feed blade 11 always rotates once per pitch of the pawl attachment 4, and the timing belt also causes the pick-up rail body 10D to return to the standby position. At times, the position of the feed blade 11 comes to the above-mentioned fixed position.

Hanger yard 12 is a hanging system that also serves as a drainer.
The small pieces of heat that have been delivered one after another are discharged in an orderly manner.

Therefore, this hanger yard 12 has a frame 12A configured with a vibrator, etc., and has a direction perpendicular to the traveling direction of the roller chain 2C so as to correspond to each of the above-mentioned pick-up rails 10, and is attached to the frame so as to have a H-shaped cross section. a pair of left and right conveyor frames 12B, a round belt pulley 12C rotatably provided at the end of the conveyor frame 12B on the low-couple chain 2C side, and a bearing with a pulley connected to the rear of the round belt pulley 12C; It consists of a round belt 12D that is wound around this bearing with a pulley.

Furthermore, the operation of the round belt pulley 12C is configured as follows.

That is, the air cylinder 10B for driving the pick-up rail
When moving from the standby position to the receiving position, the ratchet arm 12E is rotated via the ratchet bracket 12G and tie rod 12F and the round belt pulley 1
Drive 2C.

When returning to the standby position, the ratchet mechanism idles and the round belt pulley 12C does not rotate.

In addition, by changing the arm length C of the ratchet arm 12H, the air cylinder 10B for driving the pick-up rail has a stroke between each standard, but the stroke of the ratchet arm 12E
The rotation angle of the round belt 12D changes, and therefore the moving distance of the round belt 12D changes.

12G is a frame diagonally installed on the hanger yard 12 side from the C-shaped metal fitting 10C, to which the tip of the tie rod 12F is connected.

In other words, since the pick-up rail 10 and the drive source are the same, each time a small heat of that standard arrives, the round belt 12D advances by the same distance as the outer diameter of the small heat of that standard. Therefore, each size is lined up without any gaps. be able to.

The small heat on the round belt 12D does not slide on the round belt by pushing it, but the round belt moves while resting on the round belt, so there is no protrusion or crushing damage.
They line up in an orderly manner and move to the tip.

When the top of the round belt 12D is full, the worker grabs it and performs work such as banding.

Here, the effects of each of the above configurations will be explained.

Each standard has the structure shown in this figure, and when a small fever occurs, a command is sent to the air cylinder IOB for driving the pick-up rail, the pick-up rail 10 moves to the receiving position, and at the same time the delivery to the hanger yard 12 is also carried out. Once completed, return to the standby position with a return command.

[Effects of the Invention] Since the present invention is configured as described above, it produces the following effects.

1. The harvested turnips can be washed, the outer diameter of the root part measured, and sorted into each standard.

2. It is possible to work with high sorting accuracy, and
Do not damage the turnips.

Furthermore, turnips can be discharged in an orderly manner.

In particular, in the case of the present application, there is no release or dropping from supply to discharge i.

3. Two workers are sufficient: the supplier and the final processor.

4. Suppliers do not need to be skilled.
