Description

[Detailed Description of the Invention] This invention provides agricultural products such as fruits and potatoes with 1
It involves 11 mK of uniform scissors that measure at least IILJi and divide it into several classes according to its relative determination.

For example, collected potatoes are usually weighed one by one, divided into several classes according to weight, and each class is packaged according to a predetermined weight.

For fruits, etc., we further select colors and shapes.
It's packaged.

In order to improve the measurement efficiency when sorting by measuring the weight of the objects to be sorted, the weights are sequentially measured on the continuously conveyed peltone conveyor, and the measured objects are then sorted. Place the sorted cumbate on a conveyor for 9 meters and set the sorting positions according to weight class sequentially in the flow direction of the sorted cumbate.
These position sorting and sorting devices are respectively provided, and when the objects to be sorted corresponding to the classified weights 11 arrive at the corresponding sorting positions, the sorting and sorting devices are operated.
The applicant had previously filed a patent application in 1973 for a device that divides into several classes according to weight.
It was developed as 6-51673. 4 However, in the device 111c of this prior application, when the object to be sorted is transferred from the output end of the peltone conveyor of the measuring device to the input end of the sorting conveyor, the shape is like that of a potato or an apple.
! If the shape is similar, the slight impact received by the joints of the conveyor may cause the object to be sorted to roll on the sorting conveyor, causing its position to shift or falling off the sorting conveyor. Subsequent operation of the sorting and sorting device may result in incorrect sorting or failure.

Furthermore, if a device is provided that sequentially accumulates the measured values for each class, it will also include items that have fallen from the sorting conveyor, resulting in incorrect calculations.

The purpose of this invention is to improve the shortcomings of the prior invention as mentioned above, and to further improve the classification effect by class and the accuracy of cumulative calculation.

The invention is provided with a measuring device that sequentially measures the objects to be sorted one by one while being conveyed by a peltone conveyor, and a sorting conveyor very close to the discharge side, and a sorting conveyor is provided at a position above the sorting conveyor. Sorting and sorting devices are installed at predetermined intervals one after another in correspondence with the weight class from which the sorted items on the conveyor are to be removed. A confirmation station is provided to confirm whether or not a different object has arrived or passed over the Kunbe 1 Niki, and the measured weight of each object to be sorted is divided into several classes according to weight, and each The system calculates cumulatively, temporarily stores which class the object to be measured belongs to, and activates the sorting and sorting device when the object to be sorted reaches the position of the sorting and sorting device corresponding to this weight. In a device that sorts objects that are sequentially conveyed on a sorting conveyor.

The length between the carry-in end of the sorting conveyor and the sorting and sorting device located closest to the carry-in side is made slightly longer than the length sufficient for the objects to be sorted carried in from the carry-in end to be in a stable state. and two sensors for confirming the passage of objects to be sorted are provided at positions sufficient to achieve the stable state, and the objects to be sorted after passing through the sensor of the measuring device are conveyed via the two conveyors. , only when the passing signal of the spear 2 sensor is emitted within the permissible time before and after the set time, from the cumulative calculated value for each weight class, it is determined that the t-2 sensor position tK is reached within the permissible time 1 period. This continuous sorting device for agricultural products, fruits, etc. is equipped with a combinator that performs control and calculation to cancel the weight values corresponding to unsorted items.

Another invention provides a measuring device for sequentially measuring the number of objects to be sorted one by one while being conveyed by a peltone conveyor, and
111&Cff1< A sorting conveyor is provided in close proximity to the sorting conveyor, and at a position above the sorting conveyor, a sorting and sorting device is provided for each λ weighing lath, which removes the objects to be sorted on the sorting conveyor from above, in order at predetermined intervals. In addition, an M sensor is installed near the conveyor of the measuring device to check whether the object to be sorted has reached or passed onto the I/veyor of the measuring device. The measured weight of each item to be sorted is divided into several classes by weight.

The cumulative total of each is 1, and the class to which the object to be measured belongs is temporarily stored, and the sorting and sorting device is activated when the object to be sorted corresponds to the position of the sorting and sorting device corresponding to this weight. In a device for sorting objects to be sorted that are sequentially conveyed on a sorting conveyor, the objects carried in from the carrying-in end of the sorting conveyor are passed between the sorting and sorting device located on the farthest carrying-in side. The length is slightly longer than the length sufficient for the object to be sorted to be in a stable state, and the object to be sorted after passing through the two sensors is provided at a position sufficient for the object to be sorted to be in a stable state. 1. A passage confirmation signal when the passing signal of the two sets/su is issued within the allowable range of time before and after the set time when the two conveyors are transferred and conveyed; ? When the two confirmation signals are the 7V signal, the passing signal of the previous object to be sorted from the second sensor and the interval confirmation signal when the interval between the arrival signal of the object to be sorted is longer than the unacceptable time, When the object to be sorted reaches the position of the sorting and sorting device corresponding to this weight, the sorting and sorting device is activated, and when at least one of the two confirmation signals is a knot signal, K is the corresponding one. When the object to be sorted reaches the sorting and sorting device that corresponds to this weight, the sorting and sorting device does not operate and the above-mentioned knot signal is generated based on the accumulated value for each weight class. This is a continuous sorting device for patented materials, fruits, etc., characterized in that it is equipped with a computer that performs control and calculation to cancel the weight value of the object to be sorted.

The invention will now be described on the basis of exemplary embodiments shown in the drawings.

In the figure, reference numeral ``mu'' is a weight measuring device for measuring the Xt of an object to be sorted, for example, potatoes
The weight jl of potatoes B conveyed on the belt I/veyor 10 is measured several times and the average tiI&c
Therefore, measure the amount of CIL.

Reference numeral 12 denotes a sensor for confirming that the object B to be sorted has arrived at or passed through the measurement position, and is usually composed of an optical sensor having a light-emitting element and a light-receiving element.

Reference numeral 16 denotes a long sorting conveyor, which is also usually a rubber peltone conveyor, and includes a pel of the weight measuring device.
:':/The incoming end of the sorting conveyor 13 is located close to the outgoing end of the conveyor 10, and the rollers 10a are engaged with the belts at the ends of the two conveyors 10.degree. 13 that are close to each other.

The diameter of 13 m is about 173 to 115 times smaller than the diameter of the material to be sorted B, and in the case of potatoes, the diameter of the rollers 10a and 13a is 1 to 20 mm.

14 is a pulse oscillation device, and the shaft 1 of the roller 13a
A motor encoder 5 is provided to emit pulses by means of a beam of light which is determined by a gear-shaped disc 16 that rotates integrally with the conveyors 10 and 13, and emit one pulse every time the conveyors 10 and 13 move by 10 mm. It is.

Reference numeral 17 denotes a sensor 2, which is installed at a position approximately Ig from the input end of the sorting conveyor 1 in the actual drawing.
Like the spear 1 sensor, it is an optical sensor consisting of a light emitting element and a light receiving element, and is used to confirm that the object B to be sorted reaches and passes on the sorting conveyor 13. As long as the size is sufficient for the object B to be sorted to be in a stable state after transferring over two conveyors (but not limited to the above dimensions, for example, the distance between the spear 1 sensor 12 and the spear 2 sensor 17) is sufficient. The pulse oscillator [14
It is provided at a position corresponding to, for example, 130 pulses, counting the number of pulses.

Reference numerals 18 and 19 denote a sorting and sorting device which is sequentially provided on the output side of the spear 2 sensor 17, and each has the following structure in the representative embodiment shown in the figure. That is, the motor 21 of the sorting and sorting devices 1B and 19 is attached to a support frame 20 that supports the sorting roller 13, and this shaft 2
The cattle are placed directly above the sorting conveyor 16 and parallel to the transport direction, and four blade plates 22 of the same size are fixed radially to the shaft 21.
The trajectory of the tip of the conveyor 13 is arranged so as to pass close to the upper surface of the sorting conveyor 13.

It is provided so that it operates and stops by one blade interval angle for each operation command signal, and each stop position is exactly the same as each blade plate 22.
The intermediate position of the sorting conveyor 13 is the position of the sorting conveyor 13.
when it is stopped.

When the object B on the sorting conveyor 16 passes without hitting the blade plate 22 and passes exactly the position of the blade plate 22, this is one movement, that is, if there are four blade plates 22, it is 1.
When rotated by /4, the object to be sorted B is discharged from the sorting conveyor 16 and dropped onto a box 26 or a carry-out conveyor provided at the lower part of the sorting conveyor 16.

In the illustrated example, the above-mentioned sorting and sorting device is explained as two for convenience of explanation, but normally there are 5 or 6 devices, and they can be divided into 4C5-classes, rt-tF-classes, and these The installation position is such that the position of each blade plate 22 (for example, the position of the trailing edge of the blade plate) is 500 from the IF2 sensor 17.
It is provided at a distance such as pulse, 1000 pulses, etc.

Next, the above-mentioned machines and devices are controlled and operated by a computer C that performs the following control and calculations.

First, when the conveyors 10 and 13 are continuously operated at the same speed and the objects B to be sorted are sequentially fed at predetermined intervals onto the conveyor 10 of the measuring device, the weight of each M object to be sorted is sequentially measured by the weight sensor. At the same time, the weight values are divided into several stages, that is, the number of classes within the range of the number of installed sorting and sorting devices 18, 19, and these classified weight values are sequentially and independently accumulated for each class. On the other hand, the individual objects to be sorted into classes are confirmed to have passed by a spear 1/f'''12, and transferred to a sorting conveyor 13.

The object to be measured transferred to the sorting wheel 13 moves or rolls for a while due to the impact at that time, but soon becomes stable, and when it passes the position of the spear 2 sensor 17, for example, from the spear 1 sensor? Assuming that the distance to the two sensors is 160 pulses, the pulse oscillator starts measuring the number of pulses at the same time as the signal that the object to be sorted passes through the first sensor 12, and starts oscillating. In the vicinity of the eye pulse.

When the second sensor 17 passes and outputs an iM confirmation signal, this signal indicates that the object to be sorted (By) has passed the second sensor 17.
It becomes one of the AND inputs of the sorting and sorting device 18 or 19 corresponding to IiJlm and is temporarily stored in the computer, and the number of pulses from the spear 2 sensor 17 to the sorting and sorting device 181$19 is input manually. Counting begins,
For example, when 500 pulses are measured for a weight value to be distributed by the sorting and sorting device 18, an AND input with the stored signal is performed and an activation signal is given to the sorting and sorting device 18. In one movement, the objects to be sorted on the sorting conveyor are removed from the sorting conveyor 13 by the vane plate 22 of the sorting sorter 18.

Thereafter, the corresponding sorting and sorting device 18 or 19 is operated and sorted in the same manner depending on the weight of the measured value.

Next, in the specific invention of this invention, the computer further operates as follows. If the sorted object B deviates from the spear 1 sensor 12 to the spear 2 sensor 17 by more than the allowable drying time - for example, the signal that activates the 1 minute device is not memorized, and therefore even if the sorted object B Even if it reaches the position of the sorting and sorting device 18 or 19 corresponding to the weight, these are not activated and the object to be sorted is classified as non-equal class.

It is conveyed to the discharge end of the sorting conveyor 13.゛At the same time, the oscillation timing of the spear 2 sensor 17 starts.

When the period is outside the allowable range, the quantity value of the object to be sorted, which has already been accumulated or should be accumulated by the computer, is canceled from that class.

In the computer 0 of the second invention, in addition to the above-mentioned functions, the distance from when one object to be measured B passes the second sensor 17 until the first object to be measured B reaches it is too close. In other words, even when this interval is within an unacceptable range, even if the following two □ corresponding to the latter object B reach the position of the sorting and sorting device 18 or 19. It is not operated, and rather than accumulating weight values, the weight values of the two objects to be sorted that are close to each other are canceled together.

As described above, since the specific invention of this invention is constructed and operates as described above, the position of the object to be sorted B is significantly changed due to the impact when the object to be sorted is carried from the measuring device to the sorting conveyor 13. Since the sorting/distributing device 18 or 19 does not dispense the misaligned items, there is no risk of dispensing the misaligned items, and the accumulated value is also corrected. Also, even if something falls outside the sorting conveyor 16, it will be canceled from the cumulative value.
This has the effect that the amount of sorted objects of each class sorted and sorted from the sorting conveyor and the accumulated value calculated by the computer always match exactly.

In addition, in the invention of the 2nd month of the spear, even when the front and back are too close, the sorting and sorting device does not pay out the latter of these, so it is possible to accidentally put things in another class. Since there is no fear of dispensing, and even if K is not cumulatively calculated, it has the effect that the amount of sorted -B of each class sorted and distributed from the sorting conveyor always matches the cumulative value determined by the computer.

In the above-mentioned 3tF second invention, the 1,1'F2 sensor 17 issues a passage confirmation signal at the rear end of the object to be sorted, and uses the rear end of the sorting and sorting device 18 and 190 blade plate 22 as its reference position. When two objects B to be sorted in the front and back approach each other and are conveyed late, only the preceding object is brushed off by the sorting and sorting device 18 or 190 vane plate 22, and the subsequent object is sorted by another sorter. Although we have explained an example in which the separating device te↓ and not being brushed off, the reference for the n separate sorting device 18 and 190 positions is the blade p.
When it is at the center of the width of the blade plate 22, neither the front nor the front is paid out, and the reference position is set as the front rut of the blade plate 22,
The arrival signal of the tip of the object B to be sorted is used as a passing Mu signal, and of the two objects B to be sorted that are being transferred in close proximity, the following one is selected by the sorting and sorting device 118 corresponding to its weight. Or, it is an equivalent means for this invention even if 5KL is paid out by 19, and the scream suppressor 0 is used which pays out 5&C and the other one is not paid out at all.

Both the specified invention and I-2nd invention: Spear 2 Sensor 7
Since the position of the sorting conveyor is set at a sufficient size to stabilize the objects to be sorted from the carry-in end position of the sorting conveyor, the object to be sorted B after passing through the second sensor 7.
There is almost no possibility that the particles will move or fall from the belt surface of the sorting conveyor, which significantly improves sorting and cumulative accumulation.

In addition, in the control device, when the two objects B to be sorted are too close to each other and are in contact with each other (although this rarely happens), the control device is configured to prevent either object B from being dispensed. If a function is added to prevent these from operating no matter which sorting and sorting device they reach, and to cancel the two weights from the respective class-specific system integrations, the sorting accuracy will be further improved.

In addition, the temperature of the am, in which the rear edges of the sorting and sorting devices 18 and 190 vane plates 22 are the reference positions, is
A
When the preceding items are discharged by the sorting and sorting device on the upstream side of the sorting conveyor 13, the remaining items to be sorted are discharged by the sorting and sorting device corresponding to the weight of the remaining items on the downstream side. If the control device is provided with the ability to issue commands to operate, the IF-selection power is further improved. However, in this case, the following item cannot be paid out first.

If the reference position of the sorting and sorting devices 18 and 19 is set at the front track of the vane plate 22, when two objects 1 to be sorted are placed in a row, contrary to the above, the following one will be taken out first, and the remaining one will be taken out. Things,
The controller 04C may control the controller 04C so as to perform the dispensing function on the downstream side.
