Description

Combine {COMBINE}

The present invention relates to a combine having a conveying device for conveying a cutaway section.

As a combine capable of generating a quantity map by measuring the quantity of curled grains with time and correlating the yield of the grain with the harvest position in packaging, for example, the one disclosed in Patent Document 1 is already known.

According to this combine, a quantity map can be generated. Then, the operator can know the distribution of the quantity in the packaging by looking at the generated quantity map.

Japanese Patent Application Laid-Open No. 2008-212102

In the combine described in Patent Document 1, it is conceivable to construct a structure in which the quantity of the curved grain and the position of the combine at the measured timing correspond to each other as a specific structure for associating the yield of the grain with the harvest position .

However, generally, in the harvesting operation of the combine, the cut grooves are conveyed by the conveying device. Then, the interstices are tumbled during transportation or after transportation by the transportation device. After this threshing process, the number of the curved grains obtained from this trough is measured.

That is, there is a time difference between the timing at which the grooved grooves are wrapped in the packaging and the timing at which the number of grooved grooves obtained from the cut grooved grooves is measured. Between these time differences, the position of the combine changes.

As a result, the position of the combine in the timing at which the number of the grooves is trimmed is different from the position at which the number of the grooves obtained from the cut grooves is measured. That is, in the structure in which the number of the curled papers and the position of the combine in the timing at which the quantity is measured are associated with each other, the harvesting position corresponding to the quantity of the curled papers is displaced from the position where the curtains are actually cut.

Here, in the case where the time difference between the timing at which the grooved grooves are wrapped in the packaging and the timing at which the number of the grooved grooves obtained from the cut grooves are measured is constant, if the position of the combine is always detected, It is possible to calculate the position of the combine at the preceding timing by the time difference from the timing.

And, if the position thus calculated corresponds to the quantity of the curl, it is possible to avoid that the harvest position corresponding to the quantity of the curl is deviated from the position where the curl is actually cut.

However, even in this configuration, when the conveying speed in the conveying apparatus is changeable, the harvesting position corresponding to the number of the grain curls is displaced from the position where the grooves are actually cut. This is because the time difference between the timing at which the grooves between the grooves in the packaging are cut and the timing at which the number of grooves obtained from the cut grooves are measured changes with the change in the conveying speed in the conveying device.

It is an object of the present invention to provide a combine in which a deviation between a harvesting position corresponding to the number of grain ridges and a position where yarn is actually cut is less likely to occur even when the conveying speed of the conveying apparatus is changed.

A feature of the present invention is that,

A conveying device configured to convey the cut curtain along the conveying path and to change the conveying speed between the cut curtains;

A conveying speed detecting section for detecting the conveying speed,

A metering section provided below the conveying device in a conveying direction, for measuring the number of the curled pieces per unit time;

A first gas position, which is a position of the gas when the cutting gap has passed through the first point in the conveyance path, and a second position where the gap between the cut points is positioned below the first point in the conveyance direction, A position detection unit capable of detecting a position of a second base,

A conveying distance calculating section for calculating a conveying distance between the cut-out curves for each unit time based on the conveying speed and the unit time;

Based on the transfer distance calculated by the transfer distance calculating unit, the distance between the first point and the second point, the first base position, and the second base position, And a measurement position calculation section for calculating the measurement position.

In the present invention, the conveying distance is calculated on the basis of the conveying speed of the conveying apparatus. The ratio of the ratio of the transport distance to the distance between the first point and the second point and the ratio of the distance from the first base position to the actual measurement position with respect to the distance from the first base position to the second base position is a correlation . Therefore, the measurement position can be calculated with high accuracy by calculating the measurement position based on the conveyance distance, the distance between the first point and the second point, the first base position, and the second base position.

If the calculated measurement position is made to correspond to the number of the curled pieces, even when the conveying speed in the conveying device is changed, it is hard to cause a displacement between the harvesting position corresponding to the number of curled pieces and the position where the curled pieces are actually cut.

In other words, even when the conveying speed of the conveying apparatus changes, it is difficult for the present invention to cause a deviation between a harvesting position corresponding to the number of curled sheets and a position where the curtain is actually cut.

Further, in the present invention,

It is preferable that the measurement position calculation section calculate the measurement position by proportionally calculating position coordinates between the first base position and the second base position by the ratio of the carrying distance to the separation distance.

As described above, the ratio of the conveying distance to the separation distance between the first point and the second point and the ratio of the distance from the first base position to the actual measurement position with respect to the distance from the first base position to the second base position The ratios are correlated.

Therefore, when the measurement position is calculated by proportionally calculating the position coordinates between the first base position and the second base position by the ratio of the conveyance distance to the separation distance, as described above, the measurement position is calculated with high accuracy can do.

Therefore, according to the above-described configuration, it is difficult for the harvesting position corresponding to the number of the curling papers to deviate from the position where the curved portion is actually cut.

Further, in the present invention,

The conveying device is a waste conveying device having a cutting portion,

The cut waste conveying apparatus is suitably configured so as to be capable of changing the conveying speed.

In the harvesting operation of the combine, the amount of the cut-tin curves that the cut waste conveying device needs to convey per unit time varies depending on the state of the combine.

For example, the higher the traveling speed of the combine, the greater the amount of interrupted tracks per unit time. Further, the larger the amount of interrupted cuts per unit time, the greater the amount of cut-out cuts that the cut waste conveying device needs to convey per unit time.

That is, the higher the traveling speed of the combine, the greater the amount of cut-away curves that the cut waste conveying device needs to convey per unit time.

According to the above configuration, it is possible to realize a configuration in which the conveying speed of the cut waste conveying apparatus changes in accordance with the state of the combine. Therefore, it is possible to realize a configuration capable of transporting the cut slices at a conveying speed suitable for the state of the combine.

Further, in the present invention,

The cutting portion has a cutting device for cutting the grooves,

The first point is set in the vicinity of the cutting device,

And a first point passing sensor for detecting that the cutting track has passed the first point.

When the first point is set at a relatively far position from the cutting device, the time difference between the timing at which the grooves are cut and the timing at which the grooves pass through the first point becomes relatively large. As a result, the position of the base body and the position of the first base body at the timing at which the grooves are cut out are relatively large.

And, as described above, the measurement position to correspond to the quantity of the curled papers is calculated based on the first base position. Therefore, when the first point is set at a position relatively far away from the cutting apparatus, the accuracy of the measurement position to correspond to the quantity of the curled papers is relatively lowered.

According to the above configuration, the time difference between the timing at which the grooves are cut and the timing at which the grooves pass through the first point is relatively small. As a result, the position of the base body and the position of the first base body at the timing at which the grooves are cut out are relatively small.

That is, according to the above-described configuration, the accuracy of the measurement position to correspond to the quantity of the curled papers is improved.

Further, in the present invention,

A curled-up sensor for detecting the presence or absence of a curved portion is provided at a front end portion of the cut waste conveying apparatus,

The first point passing sensor is suitable if it is the curtain sensor.

According to this configuration, the manufacturing cost can be suppressed as compared with the case where the first point passing sensor is provided separately from the curved sensor.

Further, in the present invention,

The second point is suitable if it is set at the entrance of the threshing device.

When the first point and the second point are set close to each other, the first gas position and the second gas position are close to each other. And, the closer the first gas position to the second gas position, the larger the relative error of the distance from the first gas position to the second gas position.

According to the above arrangement, the first point and the second point are distant from each other as compared with the case where the second point is set above the inlet of the threshing apparatus in the transport direction. Accordingly, the relative error of the distance from the first gas position to the second gas position becomes small.

Further, in the present invention,

It is preferable that the corrugation obtained from the cut slit passing through the entrance of the threshing device is configured to be an object to be measured by the gauging section after a lapse of a predetermined time from the point of time when passing through the entrance of the threshing device.

According to this constitution, the curved grains obtained from the curved curved portions are to be measured by the measuring portion after a predetermined time elapses after the curved portions reach the second point. Thereby, the measurement at the measuring unit is started after the lapse of a predetermined time from the time when the interval reaches the second point, and the quantity is measured every unit time, and the measured quantity is sequentially associated with each of the calculated measuring positions , It becomes possible to appropriately correspond the quantity to each measurement position.

A crawler type traveling device 6 is provided under the gas of the combine A. The combine A is frequently possible by the traveling device 6.

The curtain cut by the pre-loading unit (1) is conveyed by the cut waste conveying apparatus (10) to the threshing unit (4) along the conveying path (T).

Here, the combine A is provided with an engine (not shown). The power of the engine is transmitted to a transmission (not shown) and a cut HST (not shown), respectively. Then, the power is transmitted from the transmission to the traveling device 6, and the power is transferred from the cut HST to the cut waste conveying device 10. As a result, the conveying speed of the cut waste conveying path in the cut waste conveying apparatus 10 changes substantially in conjunction with the traveling speed of the combine A. That is, the cut waste conveying apparatus 10 is configured to be capable of changing the conveying speed.

As described above, the combine A is provided with a transport device configured to transport the cut track along the transport path T and to change the transport speed between the cut grooves. In the present embodiment, the transport apparatus is the waste pick-and place carrier apparatus 10 possessed by the pre-loading unit 1.

In the threshing device (4), the cut grooves are subjected to a threshing process. The grains obtained by the threshing treatment are stored in the grapefruit tank 3. The curled piles stored in the curling tank 3 are discharged to the outside of the machine by the unloader 5, if necessary.

More specifically, the first point PA1 is set in the vicinity of the cutting apparatus 10a. The second point PA2 is set at the entrance of the threshing device 4. [ Then, the inter-curser sensor S can detect that the cut track has passed through the first point PA1.

Thus, the combine A has a first point-pass sensor that detects that the cut track has passed through the first point PA1. In the present embodiment, the first point passing sensor is the interunit sensor S.

[Configuration relating to measuring unit]

As shown in Fig. 2, the threshing device 4 is provided with a horizontal screw 41. As shown in Fig. The horizontal screw 41 extends in the lateral direction of the base body. The horizontal screw 41 transports the curl obtained by the threshing process in the threshing device 4 toward the grapefruit tank 3.

As shown in Figs. 1 and 2, a gravity device 9 is provided between the grapefruit tank 3 and the threshing device 4. As shown in Fig. The grain machine (9) has a vertical screw (91).

The curled papers conveyed by the horizontal screw 41 are conveyed upward by the vertical screws 91. [ Then, the curl carried to the upper end of the vertical screw 91 is discharged into the curling tank 3.

A measuring section M is provided near the upper end of the vertical screw 91. The metering section M measures the amount of the curved grains discharged into the curling tank 3 every unit time tu. That is, the measuring section M measures the quantity of the curled grains every unit time tu.

More specifically, the measuring section M is configured to receive a pressing force by a curvature emitted from the upper end of the vertical screw 91. Then, the measuring section M detects this pressing force. The metering section M calculates the quantity of the curled grains based on the detected pressing force. Thereby, the measuring section M measures the quantity of the curved grain.

Further, the measuring section M is provided below the waste cutting and conveying apparatus 10 in the conveying direction.

As described above, the combine A is provided below the waste cutting and conveying apparatus 10 in the conveying direction, and has a measuring section M for measuring the number of the curled pieces at each unit time tu.

[Configuration of Control Unit]

As shown in Fig. 3, the combine A is provided with a conveying speed detecting section H and a control section 7. The control unit 7 has a transport distance calculating unit 71, a measured position calculating unit 72, a quantity assigning unit 73 and a quantity distribution data storage unit 74.

The conveying speed detecting section H is configured to detect the conveying speed of the cut trail in the cut waste conveying apparatus 10 over time. The conveying speed detected by the conveying speed detecting section H is conveyed to the conveying distance calculating section 71. [

Thus, the combine A has the conveying speed detecting section H for detecting the conveying speed.

The conveying distance calculating unit 71 is configured to calculate the conveying distance between cut troughs per unit time tu on the basis of the conveying speed received from the conveying speed detecting unit H and the unit time tu.

More specifically, the conveying distance calculating unit 71 calculates the conveying distance on the basis of the conveying speed received from the conveying speed detecting unit H. The conveying distance is the distance conveyed from the first point PA1 in the conveying path T between the cut grooves.

In the present embodiment, the maximum value of the transport distance is the separation distance LM between the first point PA1 and the second point PA2. The conveying distance and the separation distance LM are all along the conveying path T.

The conveyance distance calculating unit 71 starts to calculate the conveyance distance from the point at which the cut slice started to be cut passes the first point PA1. Then, when the conveying distance reaches the separation distance LM, the conveying distance is reset and increases again from zero. Thereafter, each time the conveying distance reaches the separation distance LM, the conveying distance is reset.

In Fig. 6, an example of the transition of the conveyance distance is shown. Hereinafter, the case where the conveying distance is changed as shown in Fig. 6 will be described.

First, at time t00, the calculation of the conveyance distance starts. When the calculation of the conveying distance starts, the calculated conveying distance increases with the lapse of time. Then, at time t35, the conveying distance reaches the separation distance LM.

At time t35, the conveying distance is reset and increases again from zero. Then, between time t50 and time t60, the conveying distance reaches the separation distance LM. At this point, the conveying distance is reset and increases again from zero.

The conveying distances at eight time points from time t10 to time t80 are L1 to L8, respectively. These transport distances are calculated by the transport distance calculating unit 71 based on the transport speed and the unit time tu received from the transport speed detecting unit H and are transmitted to the measurement position calculating unit 72. [

Here, as shown in Fig. 6, the time interval between eight time points from time t10 to time t80 is unit time tu. In other words, L1 to L8 shown in Fig. 6 are conveyance distances between cut tours per unit time tu. The time interval between time t80 and time t90 is also unit time tu.

The transport distance between cut traverses per unit time tu is calculated, for example, by accumulating the product of the transport speed and the unit time tu.

Thus, the combine A has a conveying distance calculating unit 71 for calculating the conveying distance between the cut curves for each unit time tu on the basis of the conveying speed and the unit time tu.

As shown in Fig. 3, the conveying distance calculated by the conveying distance calculating unit 71 is transferred to the measuring position calculating unit 72. Fig.

3, the position detection unit 20 transfers the position information of the base of the combine A to the measurement position calculation unit 72. [

More specifically, the position detection section 20 detects the position of the gas of the combine A with a lapse of time. The position detected by the position detecting section 20 includes the first base position and the second base position.

The first base position is the position of the base when the cut-off curved line passes the first point PA1 in the conveying path T. The position of the second base is the position of the base when the second cut point PA2 passes the second cut point PA2.

Then, the position detected by the position detecting section 20 is sent to the measuring position calculating section 72 as positional information. That is, the position information transmitted to the measurement position calculation section 72 includes the position information indicating the first base position and the position information indicating the second base position.

As described above, the combine machine A is arranged such that the first gas position, which is the position of the gas at the time when the cutting track passes through the first point PA1 in the transporting path T, and the second gas position, And a position detector 20 capable of detecting a position of a second body, which is a position of the body when passing through a second point PA2 located below the first point PA2.

Further, as described above, the inter-curser sensor S detects that the cut track has passed through the first point PA1. 3, the detection result in the intergul sensor S is sent to the measurement position calculation section 72. [

The measurement position calculation section 72 calculates the measurement position of the first base body 1 from the position information received from the position detection section 20 based on the conveyance distance received from the conveyance distance calculation section 71 and the detection result received from the inter- Position information indicating a position and position information indicating a second base position are extracted.

More specifically, the measurement position calculation section 72 extracts, as positional information indicating the first base position, positional information at a time point at which the intermittent sensor S has detected that the interrupted track has passed through the first point PA1 . The measurement position calculation section 72 also extracts the position information at the time when the conveyance distance between the cut traces reaches the separation distance LM as position information indicating the second base position.

The measurement position calculation section 72 calculates the measurement position corresponding to the quantity of the curled pieces based on the conveyance distance received from the conveyance distance calculation section 71, the separation distance LM, the first base position and the second base position Is calculated.

As described above, the combine A is arranged so that, based on the conveying distance calculated by the conveying distance calculating unit 71, the separation distance LM between the first point PA1 and the second point PA2, the first base position and the second base position And a measurement position calculation unit 72 for calculating a measurement position for matching the quantity.

As shown in Fig. 3, the measurement position calculated by the measurement position calculation section 72 is transferred to the quantity assignment section 73. [ The quantity measured by the measuring section M per unit time tu is transferred to the quantity assigning section 73. [

The quantity assigning unit 73 associates the measurement positions received from the measurement position calculating unit 72 with the respective quantities per unit time tu received from the measuring unit M. [ Thereby, the quantity distribution data is generated. The quantity distribution data is data representing the distribution of the number of the curled grains in the package.

The quantity distribution data generated by the quantity allocation unit 73 is stored in the quantity distribution data storage unit 74. [ The worker can use the quantity distribution data by accessing the quantity distribution data storage section 74 through an operation terminal (not shown) or the like.

[Calculation of measurement position]

Hereinafter, the calculation of the measurement position by the measurement position calculation unit 72 will be described in detail.

As shown in Fig. 4, the combine A runs linearly in a package and turns. Thereafter, while repeating the straight traveling and turning, the intercepting grooves in the packaging are cut off.

Fig. 5 shows an example of a linear portion of the traveling path of the combine A in the package. In the harvesting operation of the combine A, as described above, the measuring section M counts the number of curved grains per unit time tu. Then, the measurement position calculation section 72 calculates the measurement position for matching each quantity in the linear travel route.

6 shows the transition of the transport distance of the cut trail calculated by the transport distance calculating unit 71 when the combine A travels on the traveling path shown in Fig. Is shown.

Hereinafter, the calculation of the measurement position by the measurement position calculation section 72 will be described with reference to Figs. 5 and 6. Fig. In addition, in the following, when the combine A travels as shown in Fig. 5, and the conveying distance between the cut-out curves changes as shown in Fig. 6, and the quantity per unit time tu is as shown in Fig. 6 .

First, in the harvesting operation of the combine A, the slit where the slicing is started passes through the first point PA1. At this time, it is detected by the inter-curved sensor S that the cut-off track has passed through the first point PA1. Accordingly, the position information of the combine A at this point is extracted by the measurement position calculation section 72 as position information indicating the first base position. In Fig. 5, the first base position at this time is shown as the position G1.

At this point, calculation of the conveying distance by the conveying distance calculating unit 71 is started. In Fig. 6, this point in time is shown as time t00.

When the calculation of the conveying distance starts at time t00, the calculated conveying distance increases as time elapses, as described above. At time t10, the conveying distance reaches L1. Thereafter, at time t20, the conveying distance reaches L2. Thereafter, at time t30, the conveying distance reaches L3. In addition, as described above, the time interval between eight time points from time t10 to time t80 is unit time tu.

Then, at time t35, the conveying distance reaches the separation distance LM. At this time, the measurement position calculation section 72 extracts the position information of the combine A at the time when the conveyance distance reaches the separation distance LM, as the position information indicating the second base position. In Fig. 5, the second base position at this time is shown as the position G2.

Here, in the present embodiment, the cut curved portion passes through the inlet of the threshing device 4, is then subjected to a threshing process in the threshing device 4, and the obtained curved grain is conveyed by the horizontal screw 41 and the vertical screw 91 And the time until the quantity of the curled grains is measured by the measuring section M becomes a fixed time tp.

That is, the combine A is configured such that the curl obtained from the cutting gap passed through the inlet of the threshing device 4 becomes the measurement target of the measuring portion M after a predetermined time tp elapses from the point of time when passing through the inlet of the threshing device 4 .

Then, based on this constant time tp, the starting point of measurement in the measuring section M is determined. More specifically, after a predetermined time tp from the point at which the conveying distance reaches the separation distance LM, the measurement of the number of the curled pieces in the measuring section M is started. After the counting of the number of the curled pieces in the measuring section M is started, the quantity is measured every unit time tu.

As shown in Fig. 6, at the time t35, the conveying distance reaches the separation distance LM. Then, at the time t85 which is after the predetermined time tp from the time t35, the counting of the number of the curled pieces in the measuring section M is started. Then, after the time t85, the number of the curled pieces is measured every unit time tu.

As shown in Fig. 6, the quantities measured at time t85, t95, and t105 are W1, W2, and W3, respectively.

In the present embodiment, the quantity of curls obtained from the interrupted tracks in unit time tu from time t00 to time t10 is regarded as the quantity W1 measured at time t85. Then, the measurement position calculation unit 72 calculates the position of the combine A at time t10 as a measurement position to correspond to the quantity W1.

Further, the quantity of the curl obtained from the interrupted tracks in the unit time tu from time t10 to time t20 is regarded as the quantity W2 measured at time t95. Then, the measurement position calculation unit 72 calculates the position of the combine A at time t20 as a measurement position to correspond to the quantity W2.

Further, the quantity of the curl obtained from the interrupted tracks in the unit time tu from time t20 to time t30 is regarded as the quantity W3 measured at time t105. Then, the measurement position calculation unit 72 calculates the position of the combine A at the time t30 as a measurement position to correspond to the quantity W3.

Here, the position of the combine A at time t10, t20, and t30 is calculated by proportionally squaring the position coordinates between the positions G1 and G2 by the ratio of the carrying distance to the separation distance LM.

More specifically, the position of the combine A at time t10 is calculated by proportionally roughing the position coordinates between the positions G1 and G2 by the ratio of the carrying distance L1 to the separation distance LM.

In other words, as shown in Fig. 5, the distance between the position G1 and the position G2 is the distance D1. The measurement position corresponding to the quantity W1 is the position of the distance di1 from the position G1. This distance di1 is calculated by multiplying D1 by the ratio of the conveying distance L1 at the time t10 to the separation distance LM.

In other words,

di1 = D1 x (L1 / LM)

.

Here, the positional coordinates in the package are expressed in the form of (X, Y) as a combination of the X coordinate and Y coordinate, the position coordinate of the position G1 is (x1, y1), the position coordinate of the position G2 is , y2).

At this time, the X-coordinate of the measurement position corresponding to the quantity W1,

x1 + (x2-x1) x (di1 / D1)

.

That is, the X-coordinate of the measurement position to correspond to the quantity W1,

x1 + (x2-x1) x (L1 / LM)

.

Likewise, the Y coordinate of the measurement position corresponding to the quantity W1,

y1 + (y2-y1) x (L1 / LM)

.

Further, the measurement position to correspond to the quantity W2 is the position from the position G1 to the distance di2. This distance di2 is calculated by the product of D1 and the ratio of the transport distance L2 at time t20 to the separation distance LM.

In other words,

di2 = D1 x (L2 / LM)

.

The X-coordinate of the measurement position to correspond to the quantity W2,

x1 + (x2-x1) x (di2 / D1)

.

That is, the X-coordinate of the measurement position to correspond to the quantity W2,

x1 + (x2-x1) x (L2 / LM)

.

Similarly, the Y coordinate of the measurement position to correspond to the quantity W2,

y1 + (y2-y1) x (L2 / LM)

.

The measurement position to correspond to the quantity W3 is the position from the position G1 to the distance di3. This distance di3 is calculated by multiplying D1 by the ratio of the conveyance distance L3 at time t30 to the separation distance LM.

In other words,

di3 = D1 x (L3 / LM)

.

The X-coordinate of the measurement position to correspond to the quantity W3,

x1 + (x2-x1) x (di3 / D1)

.

That is, the X-coordinate of the measurement position to correspond to the quantity W3,

x1 + (x2-x1) x (L3 / LM)

.

Likewise, the Y coordinate of the measurement position to correspond to the quantity W3,

y1 + (y2-y1) x (L3 / LM)

.

In this manner, the measurement position calculation section 72 calculates the measurement position by proportionally calculating the position coordinates between the first base position and the second base position by the ratio of the transfer distance to the separation distance LM.

Then, at time t35, when the conveying distance reaches the separation distance LM, the conveying distance is reset. After the time t35, the position G2 is treated as the first base position.

After the time t35, the conveying distance increases again with time from zero. Then, at time t40, the conveying distance reaches L4. Thereafter, at time t50, the conveying distance reaches L5.

Then, between time t50 and time t60, the conveying distance reaches the separation distance LM. At this time, the measurement position calculation section 72 extracts the position information of the combine A at the time when the conveyance distance reaches the separation distance LM, as the position information indicating the second base position. In Fig. 5, the second gas position at this time is shown as the position G3.

As shown in Fig. 6, the quantities measured at times t115 and t125 are W4 and W5, respectively.

In the present embodiment, the quantity of curls obtained from the interrupted tracks in the unit time tu from time t30 to time t40 is regarded as the quantity W4 measured at time t115. Then, the measurement position calculation unit 72 calculates the position of the combine A at time t40 as a measurement position to correspond to the quantity W4.

In addition, the quantity of the curled pieces obtained from the interrupted grooves in the unit time tu from the time t40 to the time t50 is regarded as the quantity W5 measured at the time t125. Then, the measurement position calculation unit 72 calculates the position of the combine A at the time t50 as a measurement position to correspond to the quantity W5.

More specifically, the position of the combine A at time t40 is calculated by proportionally roughing the position coordinates between the position G2 and the position G3 by the ratio of the carrying distance L4 to the separation distance LM.

In other words, as shown in Fig. 5, the distance between the position G2 and the position G3 is the distance D2. The measurement position to correspond to the quantity W4 is the position from the position G2 to the distance di4. This distance di4 is calculated by multiplying D2 by the ratio of the transport distance L4 at time t40 to the separation distance LM.

Then, between time t50 and time t60, when the conveying distance reaches the separation distance LM, the conveying distance is reset. Further, after this point, the position G3 is treated as the first base position.

After this point, the conveying distance increases again with time from zero. Then, at time t60, the conveying distance reaches L6. Thereafter, at time t70, the carrying distance reaches L7. Thereafter, at time t80, the conveying distance reaches L8.

Then, between time t80 and time t90, the conveying distance reaches the separation distance LM. At this time, the measurement position calculation section 72 extracts the position information of the combine A at the time when the conveyance distance reaches the separation distance LM, as the position information indicating the second base position. In Fig. 5, the second base position at this time is shown as the position G4.

Further, the quantity of the curl obtained from the interrupted track in the unit time tu from time t60 to time t70 is regarded as the quantity W7 measured at time t145. Then, the measurement position calculation unit 72 calculates the position of the combine A at time t70 as a measurement position to correspond to the quantity W7.

Further, the quantity of the curl obtained from the interrupted tracks in the unit time tu from time t70 to time t80 is regarded as the quantity W8 measured at time t155. Then, the measurement position calculation unit 72 calculates the position of the combine A at the time t80 as a measurement position to correspond to the quantity W8.

Here, the position of combine A at time t60, t70, and t80 is calculated by proportionally squaring the position coordinates between position G3 and position G4 by the ratio of the carrying distance to the separation distance LM.

More specifically, the position of the combine A at the time t60 is calculated by proportionally squaring the position coordinates between the position G3 and the position G4 by the ratio of the carrying distance L6 to the separation distance LM.

In other words, as shown in Fig. 5, the distance between the position G3 and the position G4 is the distance D3.

.

Likewise, the Y coordinate of the measurement position to correspond to the quantity W6,

y3 + (y4-y3) x (L6 / LM)

.

Further, the measurement position to correspond to the quantity W7 is the position from the position G3 to the distance di7. This distance di7 is calculated by multiplying D3 by the ratio of the transport distance L7 at time t70 to the separation distance LM.

In other words,

di7 = D3 x (L7 / LM)

.

The X-coordinate of the measurement position to correspond to the quantity W7 is,

x3 + (x4-x3) x (di7 / D3)

.

x3 + (x4-x3) x (L7 / LM)

.

Likewise, the Y coordinate of the measurement position to correspond to the quantity W7,

y3 + (y4-y3) x (L7 / LM)

.

Further, the measurement position to correspond to the quantity W8 is the position from the position G3 to the distance di8. This distance di8 is calculated by multiplying D3 by the ratio of the transport distance L8 at time t80 to the separation distance LM.

In other words,

di8 = D3 x (L8 / LM)

.

The X-coordinate of the measurement position to correspond to the quantity W8,

x3 + (x4-x3) x (di8 / D3)

.

That is, the X-coordinate of the measurement position to correspond to the quantity W8,

x3 + (x4-x3) x (L8 / LM)

.

Similarly, the Y-coordinate of the measurement position to correspond to the quantity W8,

y3 + (y4-y3) x (L8 / LM)

.

As described above, the positions of combine A at times t10 to t80 are calculated as measurement positions for respectively corresponding to the quantities W1 to W8. The positions of the combine A at times t10 to t80 are associated with each other in the order of measurement, starting from the quantity W1.

According to the structure described above, the conveying distance is calculated on the basis of the conveying speed of the cut waste conveying apparatus 10. The ratio of the conveyance distance to the separation distance LM between the first point PA1 and the second point PA2 and the ratio of the distance from the first base position to the actual measurement position with respect to the distance from the first base position to the second base position The ratios are correlated. Therefore, the measurement position can be calculated with high accuracy by calculating the measurement position based on the transport distance, the separation distance LM between the first point PA1 and the second point PA2, the first base position, and the second base position .

When the measured position thus calculated corresponds to the number of the curled pieces, even if the conveying speed in the cut waste conveying apparatus 10 is changed, a deviation between the harvesting position associated with the number of curled pieces and the position where the curled yarn is actually cut It is difficult to occur.

In other words, even if the conveying speed in the cut waste conveyer 10 is changed, it is difficult to cause a deviation between the harvesting position associated with the number of the curled pieces and the position where the curtain is actually cut off.
