The present invention relates to a combine equipped with a threshing device for performing a threshing process on a cutting gap, a grapefruit tank for storing a threshing lip, and a transfer device for transferring the threshing lip to the inside of the grapefruit tank.

The present invention also relates to a grapefruit conveying device for conveying grains from a threshing device to a grape tanks and discharging the grains to the inside of the grape tanks, And a detecting section for detecting a yield by a pressure based on the amount of the curl passing through the harvesting section.

Background Art [0002] Conventionally, as a conveying device provided in a combine of this kind, there has been known a conveying device in which, from the discharge port formed in the inside of the curling tanks, by rotation of the blade portion around the horizontal axis of the blade portion provided at the tip end portion of the screw conveyor extending in the transverse direction, (See, for example, Patent Document 1), or by rotation of the blade portion provided at the tip end portion of the longitudinally extending screw conveyor around the vertical axis, (For example, refer to Patent Document 2). [0004] In order to solve the above problems, the present invention has been made in view of the above problems.

In addition, a discharge port (" a curved discharge port ") for discharging the curved granule fed from the threshing device to the curled tank is formed in the upper portion of the curled tank, and the amount of the curled discharge discharged from the discharge port is detected Quot; pitching sensor ") disclosed in Japanese Patent Application Laid-Open No. 2001-325899. The detection portion is provided in a state of being supported on the ceiling of the grapefruit tank at a position apart from the discharge port.

Japanese Patent Application Laid-Open No. 2017-046641 (see Fig. 11) Japanese Patent Application Laid-Open No. 2014-068562 (see Fig. 4) Japanese Patent Application Laid-Open No. 2017-077204

In the case of the above-described configuration in which the threshing lips are discharged to the rear side inside the grapefruit tank by rotation of the blade around the horizontal axis, at least a part of the discharged threshing lips touches the ceiling plate of the grapefruit tank, As a result, there is a case where the slanting lip is shifted in the longitudinal direction of the inside of the grainy tank.

Further, in the case of a configuration in which the threshing lip is discharged to the front region of the discharge port by rotation of the blade portion around the vertical axis, the thrown amount with respect to the region on both the left and right sides of the discharge port is relatively small compared with the front region of the discharge port, have. In other words, when the discharge port is formed in the front-rear direction middle portion of the side wall of the curling tanks on the threshing device side, the thrown amount with respect to the front side and the rear side inside the curled tank may be relatively small. There is a case where the threshing lips are inclined in the interior of the grape-shaped tanks.

Particularly, in the case where a conveyance loop measurement device for detecting a load corresponding to the amount of the threshing lips and measuring the yield of the threshing lips is provided in the vicinity of the discharge port, the threshing lips are guided to the conveyance loop measurement device State, and it tends to be thrown to the ceiling plate of the grape-fed tank or the forward region of the discharge port, so that the above-mentioned slanting of the threshing lips becomes more conspicuous.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a combine capable of solving the above-described problem and capable of throwing a threshing liquor in a state where there is little bias in a grape tanks.

Further, in the configuration in which the curved lid is diffused and discharged from the discharge port, in the configuration in which the detection portion is disposed at a position spaced apart from the discharge port, the detection portion can detect only a part of the curved lid diffused and emitted. For this reason, for example, when a deviation occurs in the diffusion direction depending on the magnitude of the discharge amount of the grain, there is a possibility that the accuracy of the quantity detection is lowered. Therefore, the applicant of the present application proposes a combine in which a detection section (a "load detector" in the literature) is installed in a discharge case (a "discharge case" in the literature) in which a discharge port is formed in Japanese Patent Application No. 2015-254614. Thereby, the detection unit can detect all the curves sent from the threshing unit to the grape tanks.

In this proposal, vibration caused by rotation of the rotating blade is transmitted as noise to the load cell through the discharge case, though the load cell is generally used for detection of the quantity. For this reason, the load cell can not accurately detect the load of the curved line completely, and the improvement of the detection accuracy is hindered.

In view of the above, there is a demand for a harvester capable of accurately detecting the quantity of the curled pellets discharged from the curly ply conveying apparatus into the interior of the curling tanks.

A feature of the present invention resides in a trolley for trolling a cut-

A grapefruit tank for storing threshing lips,

A conveying device for conveying the threshing lips and discharging the threshing lips to the inside of the curling tanks,

And a guide portion provided on the discharge trajectory of the discharged threshing lip to change the advancing direction of the threshing lip.

According to the present invention, since the guide portion for changing the advancing direction of the threshing lips is provided on the ejection trajectory of the discharged threshing lips, the throwing direction of the threshing lips in the graining tank can be changed.

Therefore, in the case of a configuration in which the threshing lips are discharged to the rear side of the inside of the tearing tank by rotation of the blade around the horizontal axis, even if the discharged threshing lips are once thrown in the direction of the ceiling plate of the tearing tank, It is prevented from touching the ceiling plate so that it is easily thrown to the rear side of the inside of the grapefruit tank. Therefore, the thrown threshing lips can be prevented from being biased in the grapefruit tank, and can be stored in a well-balanced distribution state .

Further, in the case of a configuration in which the threshing lips are discharged in the front region of the discharge opening by rotation of the blade portion around the vertical axis, even if the discharged threshing lip is struck once in the direction of the front region of the discharge opening, It is easy to throw into the area on both left and right sides of the discharge port, that is, the front side and the back side inside the grapefruit tank. Therefore, even in this case, the thrown thrown lip can be prevented from being biased in the grapefruit tank, So that it can be stored in a good distribution state.

In the present invention, it is suitable if a direction adjusting mechanism for adjusting the traveling direction is provided.

According to this configuration, the advancing direction of the threshing lips can be changed in various directions by the direction adjusting mechanism. This makes it possible, for example, to change the proceeding direction of the threshing lips appropriately in different directions so as to be thrown to other areas in the tearing tank, if the thrown threshing lips begin to deviate to any area in the graining tank . Therefore, it is possible to more reliably prevent the threshing lips from being shifted, and to maintain the balance in a good distribution state. Further, since the traveling direction of the threshing lips guided by the guide portion may be different depending on the type and condition of the crop, the direction adjusting mechanism is provided, so that it is easy to adjust the threshing lips to thrown in a more suitable direction Loses.

In the present invention, it is preferable that the direction adjusting mechanism is capable of adjusting the traveling direction in multiple steps.

According to this configuration, since the direction adjusting mechanism can be adjusted in multiple stages, it is possible to finely set the proceeding direction of the threshing lips and prevent the threshing lips from being more reliably prevented.

In the present invention, it is preferable that the guide portion is supported by a ceiling plate of the grape tanks.

According to this configuration, since the guiding portion is supported on the ceiling plate of the grape tanks, the installation space of the guiding portion can be minimized and the storage space for the threshing lips can be sufficiently secured.

In the present invention, the ceiling plate is provided with a check port, and the guide is preferably provided on a lid for opening and closing the check port.

According to this configuration, since the guide portion is provided on the lid for opening and closing the inspection port portion, maintenance can be easily performed by removing the lid when maintenance of the guide portion is performed.

In the present invention, a check port is provided on the ceiling plate, and the guide is suitably provided in the vicinity of the check port.

According to this configuration, since the guide portion is provided in the vicinity of the check hole portion, when the maintenance of the guide portion is performed, the operator can easily carry out the operation through the check hole portion.

In the present invention, it is preferable that the guide portion is provided with a base and a liner for protecting the base.

According to this configuration, since the guide portion is provided with the liner for protecting the base portion, when the guide portion is deteriorated due to abrasion, only the liner is required to be replaced. Thus, compared with the case where the liner is not provided, .

In addition,

There is provided a detecting section which is provided at a discharge port of the curled-conveying device and which detects the quantity by the pressure based on the amount of the curled matter passing through the curled-

And the detecting unit is supported by the curling tank.

According to the present invention, since the detection portion is supported by the grapefruit tank, even if the detection portion is provided at the discharge port, the detection portion can be separated from the grapefruit transfer device. This makes it difficult for the vibration of the curled-paper conveying device to be transmitted to the detecting portion, thereby improving the detection accuracy of the quantity in the detecting portion. As a result, it is possible to detect the amount of the curled grains discharged from the curled-feed conveying apparatus into the inside of the curling tanks with high accuracy.

In the present invention,

A transverse conveying portion extending and protruding from the wall portion of the corrugated tank to the inside of the corrugated tank is provided at a longitudinal end portion of the conveying direction of the corrugated conveying device,

Wherein the discharge port is formed in an outer peripheral portion of the transverse conveyance portion,

It is preferable that the detection portion is supported by a support frame provided on a wall portion of the curled tank.

In this configuration, the wall portion and the support frame of the grapefruit tank can be used well, and the detection portion can be disposed at a position apart from the wall portion of the grape tanks. Thus, even if the discharge port is formed at a position spaced apart from the wall portion of the curling tank, the detection portion can be provided at the discharge port while being separated from the curled-type transfer device.

In the present invention,

A rotary blade is provided in the transverse conveyance portion,

And the position of the detection portion with respect to the rotating blade is adjustable.

With this configuration, since the separation distance between the rotating blade and the detection portion can be adjusted, the pressing force of the curled-up portion in the detection portion can be adjusted. Further, since the gap distance between the transverse conveying section and the detecting section can be adjusted, it is possible to prevent the grit from being caught in the gap between the transverse conveying section and the detecting section by adjusting the gap distance according to the type of grain.

In the present invention,

It is preferable that the position of the detection frame relative to the rotating blade is adjustable by changing the position of the support frame with respect to the wall portion of the curling tank.

With this configuration, the position of the detection portion relative to the rotating blade can be easily adjusted by a simple mechanism that only moves the support frame.

In the present invention,

It is preferable that the position of the detection part with respect to the support frame is changed so that the position of the detection part with respect to the rotary blade can be adjusted.

With this configuration, the position of the detection portion relative to the rotating blade can be easily adjusted by a simple mechanism that moves the detection portion relative to the support frame.

In the present invention,

It is preferable that the width of the detecting portion in the transversal direction of the gas is formed to be wider than the width of the rotating blade in the transverse direction of the gas.

According to this configuration, the curved portion extruded by the rotating blade is widely accepted by the detecting portion. Thereby, the detecting section can detect the curved portion without fail.

In the present invention,

It is preferable that the support frame extends over the side wall opposite to the curved tank.

With this configuration, since the support frame is supported at both ends in the grape tanks, the support frame is less likely to vibrate, so that the vibration of the curled-conveying device is less likely to be transmitted to the detection portion.

In the present invention,

It is preferable that the width of the detection portion in the transverse direction of the gas extends over both ends of the discharge port in the gas transverse direction.

With this configuration, the curled-up portion discharged from the discharge port is widely accepted by the detection portion. Thereby, the detecting section can detect the curved portion without fail.

The combine 1 is provided with a base frame 8 connecting a plurality of steels such as a groove shape member and a pipe material. A pair of right and left crawler type traveling devices 9 are provided under the base frame 8. On the front side of the right half of the base frame 8, an engine 11 is mounted, and an operation section 10 having a cabin structure is formed on the engine 11.

The rear portion of the base frame 8 is provided with a tilting device 2 for tilting the cutaway portion supplied from the preloading portion 2 3, a conveying device for conveying the threshing lips and discharging the same into the interior of the grapefruit tank 5, a grapefruit tank 5 for storing the threshing lips, and a threshing lips stored in the grapefruit tank 5 to the outside The unloader 12 is equipped.

The preloading section 2 is configured to be vertically liftable around the transverse shaft X1 in the transverse direction of the machine. During the non-harvesting operation such as turning, the preloading section 2 is in an elevated state, It is brought into a lowered state close to the packaging surface. The preloading section 2 is provided with a pair of right and left dividers 20 for bending the grooves and a raking reel 21 for raking the grooves backward by being rotationally driven and scraped by the raking reel 21 An auger drum 23 for feeding the cut slices cut by the cutter 22 to the rear and a cut slice sent from the auger drum 23 to the slagger 3 And a feeder 24 for feeding it to the front end.

The threshing device (3) is configured to perform a threshing process on a cutaway section supplied from a feeder (24) by a rotary motion (30) that is rotationally driven.

3, the conveying device 4 includes a threshing water collection screw 40 provided on the bottom of the threshing device 3, a lifting conveyor 41, a lateral conveying conveyor 42, 49, and is configured to be driven by receiving power from the engine 11. The lifting conveyor 41 is set up almost vertically so as to send the threshing lips discharged from the threshing device 3 upward. The lifting conveyor 41 is a bucket conveyor in which a plurality of buckets 45 are provided at regular intervals on the outer circumferential side of the endless turn chain 44 wound around the drive sprocket 43 and the driven sprocket to be.

The lifting conveyor 41 is a bucket conveyor for feeding the threshing lips discharged from the threshing device 3 upward. The lateral conveying conveyor 42 is a screw conveyor connected to the conveying end portion of the lifting conveyor 41 and for delivering the threshing lips conveyed from the lifting conveyor 41 to the inside of the graining tank 5. The lateral conveying conveyor 42 is extended in the lateral direction from the upper end of the lifting conveyor 41 and inserted in the upper portion on the front side in the left side wall 52 of the curling tank 5, (Which may be octagonal or other polygonal shape). The lateral conveying conveyor 42 has a screw shaft 47 and a screw body 48 fixed to the screw shaft 47. [

As shown in Fig. 4, a graviton discharging device 49 for diffusing and discharging the threshing lips to the inside of the grapefruit tank 5 is provided at the end area of the lateral conveying conveyor 42. As shown in Fig. The curled-paper discharging device 49 includes a discharge rotating body 412 and a discharge case 411 covering the periphery of the discharge rotating body 412. The discharge rotating body 412 is a rotating blade composed of a rotating shaft 413 extending from the screw shaft 47 and a blade plate 414 provided on the rotating shaft 413. The blade plate 414 is fixed to the rotary shaft 413 so as to protrude from the rotary shaft 413 in the radially outward direction. The blade plate 414 has a substantially flat extruded surface for extruding the threshing lips in the rotational direction thereof. The discharge case 411 is a cylindrical shape having an inner diameter slightly larger than the rotational locus of the blade plate 414. [ A part of the peripheral surface of the discharge case 411 is cut out. By this cutting, the curved discharge port 410 for discharging the threshing lips to the rear side in the interior of the grapefruit tank 5 is formed by the rotation of the blade plate 414.

The screw shaft 47 and the rotary shaft 413 rotate integrally around the horizontal shaft X2. In this embodiment, the rotation direction is set to a leftward rotation along the horizontal axis X2 with reference to the line of sight from the base end side of the screw shaft 47 to the tip end side. That is, the blade plate 414 rotates counterclockwise (around the horizontal axis) in Fig.

As shown in Figs. 4 and 5, the curved discharge port 410 is formed so as to extend in the axial direction of the discharge case 411 substantially in the circumferential direction of the discharge case 411 from the width of the blade plate 414 And a cutout opening extending from the lower end to a length of one third of the circumference in the rotational direction. The threshing lips pushed by the blade plate 414 are discharged from the discharge case 411 to the inside of the grapefruit tank 5 through the curved discharge port 410.

On the lower side of the curved discharge port 410, a load detector 7 is provided. The load detector 7 is fixed to a stay 72 straddling the support member 71 of the left side wall 52 from the support member 71 of the right side wall 51 of the grapefruit tank 5. The load detector 7 is configured to detect a load applied to the pushing action portion 70 and a load cell is provided in the pushing action portion 70. [ The pressing force of the blade plate 414 due to the rotational force of the blade plate 414 is transmitted to the pressing operation portion 70 through the threshing lips at the time of release of the threshing lip by the blade plate 414. [ And the pressure caused by this pressing causes the pressing operation portion 70 to be deformed. As the amount of the threshing lip conveyed by the conveying device 4 increases, the pressure to the threshing lip by the blade plate 414 increases. Therefore, the electric signal generated in the load cell due to the deformation of the pushing action portion 70 has a strength depending on the amount of threshing lips transported (amount of threshed lips collected: quantity), and therefore, It can be handled as a detection signal for evaluating the fluctuation or the amount.

As shown in Fig. 3, a food taste measuring device 15 for measuring the taste of the threshing lips is provided below the curved discharge port 410. As shown in Fig. The threshing lips are temporarily stored in the tasting measuring container 151 of the food-grade measuring device 15 and the curl components such as moisture and protein are measured through spectroscopic measurement for the threshing lips.

The graininess measuring device 15 is configured to measure the graininess of the grains discharged from the grazing discharge port 410 because the grains fed by the transverse conveying conveyor 42 are going to fall on the same track as when the horizontally projected object falls freely, But is located at a position slightly offset toward the right side wall 51 of the grapefruit tank 5, as shown in Fig. As a result, it is possible to efficiently store the threshing lips in the tasting measuring container 151 of the tasting device 15.

The curling tanks 5 are disposed on the right rear side of the base frame 8 and are positioned on the rear side of the operation section 10 on the right side adjacent side of the threshing device 3. A lifting conveyor 41 for supplying a threshing liquor from the threshing device 3 to the grapefruit tank 5 is disposed between the threshing device 3 and the grapefruit tank 5.

As shown in Figs. 4 and 5, a planar guide portion 6 is supported on the ceiling plate portion 50 of the grapefruit tank 5. In the present embodiment, since the guiding portion 6 is supported on the ceiling plate portion 50 of the grape tanks, the installation space of the guiding portion 6 can be minimized and the storage space for the threshing lips can be sufficiently secured .

The guide portion 6 is welded to the rotating rod 61 through the connecting portion 60. The rotating rod 61 is supported by the supporting member 62 fixed to the ceiling plate portion 50, As shown in Fig. The rotating rod 61 is provided with one end pierced through a through hole (not shown) formed in the left side wall 52 of the grape tanks.

4 and 6, the threshing lips K discharged from the curled-up discharger 49 are struck once in the direction of the ceiling plate portion 50 of the grapefruit tank 5 The traveling direction of the water surface is changed by the guide portion 6 and is prevented from touching the ceiling plate portion 50 so that it is liable to be thrown to the rear side (the right side of the paper in Figs. 4 and 6) inside the grapefruit tank 5 It is possible to prevent the projected threshing ribs K from being biased in the grapefruit tank 5 and to store the grains in a well-balanced distribution state.

The rotation rod 61 and the connecting portion 60 and the guide portion 6 are rotated in the horizontal direction X3 by rotating the operation lever 63 around the horizontal axis X3 of the rotary bar 61, So that it can rotate integrally. Therefore, it is possible to change the angle of the guide portion 6 by operating the operation lever 63, whereby the advancing direction of the threshing lips can be adjusted. That is, in this embodiment, the direction adjusting mechanism for adjusting the advancing direction of the threshing lips is constituted by a supporting member, a rotating rod 61, a connecting portion 60, and a manipulating lever 63.

According to the above configuration, the advancing direction of the threshing lips can be changed in various directions by the direction adjusting mechanism. Therefore, for example, if the projected threshing lips begin to deviate to some area in the grapefruit tank 5, the progress direction of the threshing lips is appropriately changed in the other direction, . Therefore, it is possible to more reliably prevent the threshing lips from being shifted, and to maintain the balance in a good distribution state. The direction of the threshing lips guided by the guide portion 6 may differ depending on the type and condition of the crop, so that the threshing lips can be thrown in a more suitable direction by providing the direction adjusting mechanism It becomes easy to adjust.

In addition, the direction adjusting mechanism is not limited to the above-described configuration. For example, the guide portion 6 may be suspended at two points, that is, the front end and the rear end, (For example, a stay having a plurality of bolt holes and a bolt may be combined to adjust the length of the stay by changing the hole through which the bolt is inserted), or alternatively, A motor or the like, or may be configured to be adjustable in orientation by using a known automatic tension system without regard to manual or motorized operation.

It is preferable that the direction adjusting mechanism is configured to be able to adjust the traveling direction in multiple steps. For example, in the above-described embodiment, a known configuration capable of changing and maintaining an angle around the horizontal axis X3 of the operation lever 63 may be employed.

According to the above configuration, since the direction adjusting mechanism can be adjusted in multiple steps, it is possible to finely set the proceeding direction of the threshing lips and prevent the threshing lips from being more reliably prevented.

The direction adjusting mechanism may be provided as required. That is, the guide portion 6 is fixed to the ceiling plate portion 50 of the grapefruit tank 5, and the angle can not be changed.

The position where the guide portion 6 is provided is not limited to the above-described embodiment and the position of the installation of the guide portion 53 is not limited to the above- The guide portion 6 may be provided on the lid 54 for opening and closing the check valve portion 53 or may be provided near the check valve portion 53 on the front side.

[ In the case where the guide portion 6 is provided in the vicinity of the check valve portion 53 and the maintenance of the guide portion 6 is performed, the operator can easily carry out the inspection through the check valve portion 53. [

Particularly, in the case where the guide portion 6 is provided on the lid 54, in order to prevent the rising pressure of the stored threshing lip from being caught by the guide portion 6, for example, a suitable rod member and a rod member And the lid 54 is pushed up by a predetermined upward pressure by the threshing lips to act on the lid 54 so that the rod member is held by the leaf spring 54. [ So that the lid 54 is opened.

[Grain-fed conveying device]

As shown in Fig. 14, the threshing apparatus 1006 and the grapefruit tank 1007 are connected to each other by a grained paper transporting apparatus 1010. Fig. A curling conveyance screw 1010A provided at the bottom of the curling apparatus 1006 and a lifting conveyor 1010B disposed between the curling apparatus 1006 and the curling tank 1007 are provided in the curling conveyance apparatus 1010, There is provided a transverse conveying section 1011 penetrating through the front upper portion of the left side wall 1007a of the curling tank 1007. [ The lifting conveyor 1010B is a bucket conveyor in which the endless rotary chain 1010E is wound around the sprocket 1010D to extend across both ends of the lifting conveyor 1010B in the conveying direction, And buckets 1010F are installed at regular intervals. The curl recovered at the bottom of the curling apparatus 1006 is discharged to the right lateral side of the curling apparatus 1006 by the curling conveying screw 1010A and then conveyed to the outside of the curling tank 1007 by the lifting conveyor 1010B. And is conveyed inward from the outside of the grapefruit tank 1007 by the transverse conveyance unit 1011. [

14 and 15, a lateral conveying screw 1012, a flat plate-like rotating blade 1013, and a discharge case (not shown) for covering the periphery of the rotating blade 1013 are attached to the transverse conveying portion 1011 1014 are provided. The rotary shaft 1012a extends from the transverse conveying screw 1012 toward the end in the conveying direction and the rotary shaft 1012a rotates integrally with the transverse conveying screw 1012. [ The rotating blade 1013 extends in one direction from the rotating shaft 1012a and the rotating blade 1013 rotates about the axis P100 of the rotating shaft 1012a. A discharge port 1014a is formed in a C shape as viewed from the base side of the discharge case 1014 at the back side of the base body, that is, at a portion indicated by the one-dot chain line in Fig. The width of the discharge port 1014a in the axial direction of the rotary blade 1013 is set larger than the width of the rotary blade 1013. [ The rotary blade 1013 rotates in the direction indicated by the arrow R and the curl sent out to the discharge case 1014 is extruded from the discharge port 1014a into the interior of the curling tank 1007 by the rotary blade 1013 .

The protruding portion 1015 is provided so as to protrude from the rotating shaft 1012a to the opposite side of the rotating blade 1013. [ The rotation of the projection 1015 is detected by a rotation sensor (not shown), and a rotation pulse is generated at the timing when the projection 1015 passes the rotation sensor, and one rotation is counted.

[Detector]

As shown in Figs. 15 to 17, a detection unit 1020 for measuring the amount of discharge of the curled-up material is provided adjacent to the discharge port 1014a. The detection portion 1020 is supported by the support frame 1030 and the support frame 1030 extends over the left side wall 1007a and the right side wall 1007b among the wall portions of the grapefruit tank 1007. [ A detection plate 1021 and a load cell 1022 are provided in the detection unit 1020 with a spacer 1023 interposed therebetween. As shown in Fig. 16, one end 1022A of the load cell 1022 is supported by a support frame 1030 with a spacer 1024 interposed therebetween. A detecting plate 1021 is provided above the other end 1022B of the load cell 1022 with a spacer 1023 therebetween.

The detection plate 1021 is formed in a flat plate shape and is inclined rearward and upward along the tangential direction of the rotating blade 1013 in a state in which the tip of the rotating blade 1013 closest to the detection plate 1021 . The width of the detection plate 1021 extends to the left and right width of the ejection opening 1014a and the detection plate 1021 is formed such that the width of the detection plate 1021 is wider than the width of the left and right sides of the rotation blade 1013 have. Thus, all of the curled particles discharged over the entire width of the left and right width of the discharge port 1014a are pressed against the detection plate 1021 and the detection unit 1020 removes the curled particles discharged from the curled- Can be detected. Further, since the detection plate 1021 is inclined rearward and upward, the curled-up pushed against the detection plate 1021 is blown to the rear portion of the curled-up tank 1007.

As shown in Fig. 17, a screw hole 1022a opened downward is formed at one end 1022A of the load cell 1022. As shown in Fig. The bolt is inserted through the elongated hole 1031c formed in the support frame 1030 and penetrates through the insertion hole 1024a formed in the spacer 1024 and is bolted to the screw hole 1022a. Thereby, the one end 1022A of the load cell 1022 is cantilevered to the support frame 1030 with the spacer 1024 interposed therebetween.

Although not shown, a screw hole opened upward is formed in the other end portion 1022B of the load cell 1022. A bolt insertion through hole corresponding to this is formed in the detection plate 1021 and the spacer 1023 have. A bolt is inserted through the insertion hole formed in the detection plate 1021 and through the insertion hole formed in the spacer 1023 and is bolted to the other end 1022B of the load cell 1022. [

As described above, the load cell 1022 is cantilevered to the support frame 1030 and the spacers 1023 and 1024 are arranged symmetrically with respect to the load cell 1022, Stress is more likely to be concentrated on the upper surface 22C. That is, when the load cell 1022 receives a load from the detection plate 1021, a moment load is applied to the other end portion 1022B, and deformation occurs in the center portion 1022C.

A deformation occurs in the central portion 1022C of the load cell 1022, so that an electrical signal is generated from the load cell 1022. [ This electric signal is used as a detection signal for evaluating the number of the curled pieces, and the electric signal is indicated by, for example, a voltage value or a current value. As the discharge amount of the curled paper fed from the curled-paper conveying apparatus 1010 increases, the pressing force of the curled paper against the detection plate 1021 increases, and the detection signal of the load cell 1022 also increases.

With the configuration in which the detection plate 1021 and the discharge port 1014a are adjacent to each other, the detection portion 1020 can easily detect the curvature discharged from the discharge port 1014a, and therefore the detection accuracy of the quantity is improved. Since the centrifugal force is applied to the rotating blade 1013 and the protruding portion 1015 when the rotating blade 1013 rotates, the centrifugal force of the rotating blade 1013 and the centrifugal force of the protruding portion 1015 are balanced The rotational center of gravity is biased, and vibration due to the rotation of the rotating blade 1013 occurs. The rotational vibration of the rotating blade 1013 is transmitted to the detection plate 1021 through the discharge case 1014 and the load cell 1022 ). Therefore, the rotational vibration of the rotating blade 1013 becomes noises and is detected by the detecting unit 1020, which hinders the accuracy improvement of the quantity detection. The support frame 1030 for solving this problem will be described below.

[Support frame]

15 to 17, the detection unit 1020 is provided at the discharge port 1014a in a state of being separated from the transverse conveyance unit 1011, and the detection unit 1020 is supported by the support frame 1030 have. Wall frames 1071 and 1071 are installed horizontally on the left and right walls 1007a and 1007b of the wall of the curling tank 1007 along the gas longitudinal direction. The support frame 1030 is composed of, for example, a combination of a mountain type steel, and includes a support member 1031 extending across the left and right ends of the graining tank 1007, a pair of right and left welded and fixed to both left and right ends of the support member 1031 And a mounting member 1032 for mounting the light emitting diodes. The mounting member 1032 is bolted to the left and right wall frames 1071 and 1071 so that the support frame 1030 is supported at both ends of the grappling tank 1007.

As shown in Fig. 17, the support member 1031 is formed in an L-shape as viewed in section. The support member 1031 is formed in such a shape that the V-shaped member is inverted in the vertical direction as viewed from the side of the base and has a rear upper inclined portion 1031a inclined rearwardly upward, And a rear lower inclined portion 1031b that is inclined rearward and downward. Since the rear upper inclined portion 1031a supports the detection portion 1020, the rear upper inclined portion 1031a is formed wider than the lower surface of the spacer 1024 in the front-rear width. The left and right end portions of the rear upper inclined portion 1031a are formed with cutout portions 1031d and 1031d. The cutout portions 1031d and 1031d are formed in a flat plate shape bent against the rear upper inclined portion 1031a and in parallel with the left and right side walls 1007a and 1007b. The left and right cutouts 1031d and 1031d and the side portions 1032b and 1032b formed on the left and right mounting members 1032 and 1032 are welded and fixed, respectively.

15 and 17, in the rear upper inclined portion 1031a, elongated holes 1031c and 1031c along the forward and backward direction are provided at positions corresponding to the base end side of the cantilever support of the load cell 1022 And are arranged in the left and right directions. Two bolts are inserted and fastened to the respective long holes 1031c and 1031c, so that the detecting portion 1020 is bolted to the supporting member 1031. [

In this way, the detecting portion 1020 is supported by the support frame 1030 and separated from the transverse conveying portion 1011, and the detection plate 1021 and the ejection orifice 1014a are adjacent to each other, It is difficult for the detection unit 1020 to detect the pressing force of the curled particles discharged from the rotating blade 1013 and to transmit the vibration caused by the rotation of the rotating blade 1013 to the detection unit 1020. [

The detecting portion 1020 is configured to be slidable along the elongated hole 1031c on the supporting member 1031 in a state where the bolt joining the detecting portion 1020 and the supporting member 1031 is not fastened. Here, the rear upper inclined portion 1031a of the support member 1031 is inclined so as to be parallel to the inclination angle of the detection plate 1021, corresponding to the inclination of the detection plate 1021 of the detection portion 1020 upward Loses. The long hole 1031c follows the tangential direction of the rotating blade 1013 when the tip of the rotating blade 1013 comes closest to the detecting plate 1021. [ Therefore, the position of the detection portion 1020 relative to the support frame 1030 can be changed along the tangential direction of the rotating blade 1013. In this manner, the position of the detecting portion 1020 relative to the rotating blade 1013 can be adjusted. The gap between the lower front end of the detection plate 1021 and the lower end of the discharge case 1014 can be adjusted along the tangential direction of the rotary blade 1013. The gap may be appropriately changed, but it is preferable that the clearance is 8.5 mm or so, for example, so that the gap is not caught.

As shown in Figs. 15 to 18, the left and right mounting members 1032 and 1032 are formed in an L-shaped cross section, and in the state in which the long side direction is along the gas longitudinal direction, , And 1032 are horizontally stacked on the wall frame 1071 and 1071. [ The mounting member 1032 has a lower portion 1032a abutted against the wall frame 1071 and a side portion 1032b welded and fixed to the half portion 1031d of the support member 1031. [ Long holes 1032c and 1032c along the gas longitudinal direction are formed in the lower portion 1032a in a state in which they are arranged in the gas front and rear direction of the mounting member 1032. [ Bolt insertion through holes 1071a and 1071a are formed in the wall frame 1071 so that the mounting holes 1071a and 1071a engage with the long holes 1032c and 1032c.

The mounting holes 1071a, 1071a, 1071a and 1071a formed in the right and left wall frame frames 1071 and 1071 are engaged with the long holes 1032c, 1032c, 1032c and 1032c formed in the right and left mounting members 1032 and 1032, The bolts are inserted and fastened in the joined state, so that the support frame 1030 is bolted to the left and right wall frames 1071 and 1071. [

The right and left mounting members 1032 and 1032 are attached to the left and right wall frames 1071 and 1071 in a state in which the bolts joining the left and right mounting members 1032 and 1032 and the left and right wall frames 1071 and 1071 are not fastened. 1071 are slidable along the long hole 1032c. Therefore, the position of the support frame 1030 relative to the left and right side walls 1007a, 1007b of the curling tank 1007 can be changed. In this respect, the distance between the rotating blade 1013 and the detection plate 1021 can be adjusted along the horizontal direction, and the pressing force of the curved surface against the detection plate 1021 can be adjusted. The clearance between the lower front end of the detection plate 1021 and the lower end of the discharge case 1014 can be adjusted along the horizontal direction.
