BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention detects a so-called rooting material from logs to be lumbered, and, for example, a rooting material detection device for discharging the rooting material from a regular transport line, The present invention relates to a peeling facility incorporating a rooting material detection device.

[0002]

2. Description of the Related Art Normally, when felling lumber, a so-called "first ball" (a portion of a predetermined length from the root of the timber, a portion above it is sequentially called a "second ball", "Third ball"
In order to secure as long as possible, the timber is cut down at the thick part of the root. The root portion of the timber has a shape in which the diameter is enlarged in a tapered shape with respect to the upper portion, and this is called "rooting". In other words, the timber felled for the above purpose is
The root is provided with the above-mentioned rooting. still,
The same applies to domestic timber and imported timber.

[0003]

The above-mentioned conventional configuration has the following problems. That is, as described above, the felled log has a rooted portion on the root side of the log, that is, a portion in which its diameter is enlarged in a taper shape, regardless of whether it is domestic timber or imported timber. There is a problem in that the smoothing of the subsequent lumbering work is impaired. For example, when the log is conveyed by a roller conveyor or the like, the root of the log may be caught on each roller, which may stop the log conveyance. In addition, there is a peeling process for peeling off the logs from the logs during the lumbering process, which is performed by a peeling device such as "Ring Barker (trade name)". that time,
A device with a large diameter is required in accordance with the diameter of the root of the log, which leads to an increase in the size of the peeling device. Also, due to the presence of the root portion, the outer circumference of the log is in contact with the arm part of the peeling device, and not in contact with the cutter part located slightly on the inner circumference side of the arm part. However, it may be gripped by the peeling device side, which makes it impossible to perform the necessary peeling treatment. Further, usually, the remaining material after removing a necessary portion (for example, a square material) from a log is sent to a paper manufacturing process as a wood chip. However, there is a case where the peeling is insufficient for the rooted portion, and therefore, the skin may be mixed in the wood chip. This significantly reduces the quality of the paper obtained by papermaking. Further, the work of removing the skin portion from the wood chip is also extremely difficult. As described above, the presence of rooting has been a factor causing many problems in the subsequent lumbering process and the like.

The present invention has been made on the basis of such a point, and an object of the present invention is to make it possible to detect whether or not a log is a rooting material, thereby causing the above-mentioned problems. An object of the present invention is to provide a rooting material detection device capable of preventing the occurrence of the above-mentioned occurrence, and a peeling facility incorporating such a rooting material detection device.

[0005]

In order to achieve the above-mentioned object, a rooting material detecting device according to the present invention has a projecting section and a log at the projecting section at least at a front end portion or a rear end portion of a transported log. A log outer diameter measuring mechanism that continuously or intermittently measures the outer diameter of the log by an optical sensor or a touch sensor that is arranged so as to face each other, and a log measured by the log outer diameter measuring mechanism. If the variation of the outer diameter of the above exceeds a preset set value, it is treated as a rooting material, and a discriminating mechanism is provided. At that time, a log position detecting mechanism for detecting the front end or the rear end of the log is installed in the middle of the log transport path, and the outer diameter of the front end or the rear end of the log is continuously determined based on the signal from the log position detecting mechanism. It is conceivable to install a log outer diameter measuring mechanism that measures intermittently or intermittently. Further, by arranging one set of optical sensors each consisting of a light projecting section and a light receiving section in two directions orthogonal to each other, the discriminating mechanism preliminarily detects fluctuations in the outer diameter of the log measured by at least one of the optical sensors. When the set value exceeds the set value, it may be treated as a rooting material.

Further, the peeling equipment according to the present invention comprises a peeling device comprising a peeling portion and a log feeding conveyor mechanism arranged before and after the peeling portion and a log feeding conveyor mechanism, and the above log feeding conveyor mechanism or log feeding conveyor mechanism. The rooting material detection device according to any one of claims 1 to 3, which is arranged on an arbitrary conveyance path in front of the device. At that time, the transport path is arranged in front of the log feeding conveyor mechanism of the peeling device, a plurality of logs are carried in, a log feeding mechanism that feeds the logs laterally by a conveyor and supplies the logs to the log feeding conveyor mechanism side, A log separating mechanism arranged between the log supply mechanism and the log feeding conveyor mechanism to separate the log supplied from the log feeding mechanism while laterally feeding it by a separating conveyor; and the log separating mechanism and the log feeding conveyor mechanism. A first rooting material detection unit that receives one log that is separated and supplied by the log separation mechanism and is transported in the longitudinal direction of the log by a conveyor, and a first rooting material detection unit that transports it. A second rooting material detecting section that receives the logs to be transported and conveys them to the log feeding conveyor mechanism side by a conveyor as they are. A rooting material detecting device is arranged between the projecting portion and the second rooting material detecting portion, and the second rooting material detecting portion is rotatably arranged on the log feeding conveyor mechanism side and the opposite side thereof. When the log is detected as a rooting material by the tensioning material detection device, the log is rotated to the side opposite to the log feeding conveyor mechanism side to eliminate the log and the discrimination mechanism determines that the log is not a rooting material. In this case, it is conceivable to provide a distribution mechanism that rotates to the log feeding conveyor mechanism side to supply the log to the log feeding conveyor mechanism side. or,
A bypass mechanism is arranged between the log separating mechanism and the log feeding conveyor mechanism, and the bypass mechanism is arranged so as to straddle the first rooting material detecting section, and the conveyor mechanism is arranged so as to have the first rooting member. It is conceivable that it is composed of a cylinder mechanism that appears and disappears on the material detection unit. Further, it is conceivable to provide a log stocking mechanism composed of a conveyor between the second rooting material detecting section and the log feeding conveyor mechanism for stocking logs. Also, a log traverse mechanism that traverses logs by rollers is installed at the rear end of the log separating mechanism, and a stopper is arranged at one end of the log traverse mechanism and a log cutting mechanism is arranged at the other end. However, it is conceivable to provide a control mechanism for controlling the log cutting mechanism to cut and remove a portion exceeding a predetermined length in a state where the log is laterally fed by the log lateral feeding mechanism until it abuts the stopper. Further, a pressing mechanism is arranged in front of the peeling device, the rooting material detection device detects whether or not the log is the rooting material, and when the log is determined to be the rooting material, It is conceivable to provide a control mechanism that delays and controls the timing of pressing by the pressing mechanism and the timing of closing the cutter portion of the peeling device by a predetermined amount. Further, a detection mechanism for detecting the rear end of the log is installed in the second rooting material detection unit, and when the rear end of the log is detected by the detection mechanism, the log of the log by the conveyor of the second rooting material detection unit is detected. It is conceivable to provide a control mechanism for stopping the transport and thereby determining the position of the logs.

[0007]

In other words, the rooting material detection device according to the present invention is
First, the outer diameter of a log that is conveyed is measured continuously or intermittently at a certain distance from at least the front end or the rear end. Then, when the variation of the outer diameter exceeds a preset value, this is discriminated as a rooting material and, for example, it is discharged from a regular conveying line.

Further, in the peeling equipment according to the present invention, the rooting material detecting device as described above is arranged at the log feeding conveyor mechanism of the peeling device or at an arbitrary conveying position before this, and before the logs are put into the peeling device. In addition, whether or not the material is a rooting material is determined, and when the material is a rooting material, for example, the material is discharged without being put into a peeling device.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.
An example will be described. This embodiment shows a stripping equipment having a construction in which the rooting material detecting device according to the present invention is incorporated on the primary side. As shown in FIG. 1, there is a peeling device 1, and this peeling device 1 includes a peeling portion 3 and a primary side of the peeling portion 3 (in FIG. 1).
And log infeed conveyor mechanism 5 disposed on the right side), and a conveyor mechanism 7 for feeding logs arranged on the secondary side of the stripping section 3 (left side in FIG. 1). The peeling part 3
Includes a plurality (for example, three) of arm portions 3a (shown in FIG. 9) that can be freely opened and closed.
A cutter portion 3b (shown in FIG. 9) is attached to the tip of the. The log 9 is thrown into the space between the three arm portions 3a of the peeling section 3 by the log feeding conveyor mechanism 5 and is peeled off by the three cutter sections 3b when passing therethrough. Then, it is discharged by the log delivery conveyor mechanism 7.

On the primary side of the peeling device 1 having the above structure,
First, the log supply mechanism 11 is arranged. A plurality of logs 9 are carried into the log supply mechanism 11 by, for example, a forklift. In addition, the plurality of logs 9 carried into the site may have non-uniform origins and end openings, non-uniform lengths, or misaligned axial positions. Particularly, when a plurality of logs 9 are carried in by a truck or the like, it is usual to stack them by alternately arranging the main opening and the end opening due to the efficiency of loading. As you can see, the front end and end end are not aligned. Then, if it is directly loaded onto the log supply mechanism 11 by a forklift or the like, it is natural that the front end and the end end are not uniform, the lengths are not uniform, and the axial position is not fixed. It may be out of alignment. A log separating mechanism 13 for separating and supplying a plurality of logs 9 one by one is arranged on the secondary side (upper side in FIG. 1) of the log supplying mechanism 11 by a forklift or the like. The logs 9 continuously supplied from the log supply mechanism 11 are separated and supplied one by one by the log separation mechanism 13. The logs 9 separated one by one by the log separating mechanism 13 are supplied to a first rooting material detection unit 15 for determining whether or not the logs 9 are rooting materials. A second rooting material detection unit 17 is also arranged on the right side of the first rooting material detection unit 15 in FIG. 1, and the log 9 is moved from the first rooting material detection unit 15 to the second rooting material detection unit 15. 17
While being conveyed to the side, the rooting material detection mechanism 19 detects the rooting material. That is, log 9
The outer diameter is measured at a predetermined interval over the entire length of the, and it is determined whether or not the variation in the measured value exceeds a preset value within a predetermined distance from the rear end. It is used as upholstery material. In addition, the front end referred to here is a front end and a rear end in the transport direction from the first rooting material detection unit 15 to the second rooting material detection unit 17, and for the peeling device 1, after all, The rear end becomes the front end. When there is a variation in the measured value that exceeds the set value at the rear end portion (between the rear end and the predetermined distance), this is used as the rooting material. In addition, when measuring the outer diameter, as described above, in addition to being performed at a predetermined interval in the entire length of the log 9, for example, the rear end of the log is provided with another sensor 20 (with respect to the rooting material detection mechanism 19, It is arranged at the rear of the conveying direction by a predetermined interval), and when the sensor 20 detects the outer diameter, the rooting material detecting mechanism 19 starts to measure the outer diameter, and then the rear end of the log 9 is reached. The outer diameter may be measured only during the period. Also, while measuring the outer diameter of the rear end of such a log 9,
It is conceivable to do this at the tip as well. In this case, for example, if it is detected by measuring the outer diameter of the tip portion that the root is located at the tip, the root is the rear end for the peeling device 1. However, it does not cause any trouble, and is therefore treated as a non-rooting material at that stage.

Whether the log 9 is a rooting material is determined by the first rooting material detecting unit 15 and the second rooting material detecting unit 17, and if the log 9 is not the rooting material, the upper side in FIG. It is conveyed to the log stock mechanism 21 side which is arranged. On the other hand, when the log 9 is the lining material, it is discharged to the lower side in FIG. Then, it is inverted by 180 ° by a forklift or the like, and in the state where its orientation (the orientation of the end opening and the original opening) is changed, it is loaded again on the log supply mechanism 11 already described. That is, even if the log 9 is a lining material, if the log 9 is put into the peeling section 3 of the peeling apparatus 1 from the end opening side thereof, no trouble occurs in the peeling section 3. On the other hand, when the peeling device 3 is put into the peeling portion 3 of the peeling device 1 from the side having the root, the obstacle may occur in the peeling portion 3. Therefore, in this case, after being once discharged, it is inverted by 180 ° as described above, and then it is charged again on the log supply mechanism 11. As a result, the root with the roots becomes the rear end with respect to the peeling portion 3,
The peeling section 3 will not cause any trouble. The rate at which the peeling device 1 causes a trouble due to the lining material will be described. Generally, a peeling device 1
The rate of the tying material that causes problems for the
%. Further, as described above, when the peeling device 1 is inserted in such a positional relationship that the root having the root is the rear end, no trouble occurs. Then, about half of the logs 9 are put into the peeling device 1 through the end opening, so that about 10% of the 20% of the logs 9 are eventually removed as the rooting material. And about them,
In the case of this embodiment, the peeling device 1 is turned over after being discharged.
I am trying to throw it in.

The logs 9 conveyed to the log stock mechanism 21 are supplied one by one from there to the log feeding conveyor mechanism 5 side of the peeling device 1 already described, and then fed into the peeling section 3 from there. Become. A bypass mechanism 23 is arranged on the upper side in FIG. 1 of the first rooting material detection unit 15.
The bypass mechanism 23 serves to bypass the second rooting material detection unit 17 and directly supply the log 9 that does not require rooting detection to the peeling device 1 side.

The above description is a schematic configuration of the peeling equipment according to the present embodiment, and the configuration of each part will be described in detail below. First, the log supply mechanism 11 and the log separation mechanism 13 are configured as shown in FIGS. 2 and 3.
First, the log supply mechanism 11 is configured as a feed conveyor by stretching a plurality of transport chains 27 on the stacking table 25 in parallel. Further, as shown in FIG. 3, a drive motor 29 for rotating the plurality of transport chains 27 is arranged on the stacking table 25, and the rotation of the drive motor 29 is transmitted via a rotation transmission mechanism 31. , Will be transmitted to the side of the plurality of transport chains 27. And a plurality of logs 9 supplied by the forklift
Are sequentially supplied to the log separating mechanism 13 side by rotating intermittently.

Further, the log separating mechanism 13 is configured as a so-called separating conveyor, and first, in a state where two pairs of left and right (four in total) first transport chains 33a ---- are inclined upward. It is arranged. Further, on the secondary side in the transport direction of the first transport chains 33a, another pair of left and right second transport chains 33b (four in total) are similarly arranged in an upwardly inclined state. The first transport chain 33a and the second transport chain 33b are installed on the base 35. Among the first transport chains 33a, the left side pair of first transport chains 33a, 33a has a log 9
A receiving member 37 having a level lower than the outer diameter of the is attached at a predetermined interval. Further, a receiving member 37 having a level lower than the outer diameter of the log 9 is attached to the pair of first transport chains 33a, 33a on the right side at a predetermined interval. This is the same on the side of the second transport chain 33a, and the receiving members 37 having the same structure are attached at predetermined intervals.

Support frames 39 and 39 are installed on the left and right sides of the four first transport chains 33a, and resistors 41 and 41 are fixed to the support frames 39 and 39, respectively. The upper surfaces of these resistors 41 are, as shown in FIG.
It is formed in a sawtooth shape. This is the same on the side of the four second transport chains 33b, and support frames 39 and 39 are installed on the left and right sides of the second transport chain 33b. 41 and 41 are fixed respectively. The upper surfaces of these resistors 41 are formed in a sawtooth shape as shown in FIG. And the log 9 is
It is conveyed while being supported by the receiving member 37. At this time, the logs 9 are separated one by one by the action of the resistor 41. That is, if two logs 9 are supported by the receiving member 37, a rotating force in the clockwise direction in FIG. 3 is applied to the log 9 in the front in the transport direction by the action of the resistor 41. At the same time, a rotational force in the counterclockwise direction in FIG. 3 is applied to the log 9 behind it. Thereby,
The log 9 at the rear is in a state of easily overcoming the receiving member 37 and is pushed to the rear of the receiving member 37. As a result, only one log 9 is eventually supported and conveyed by the receiving member 37. In this way, the plurality of logs 9 are separated. Incidentally, reference numeral 4 in FIG.
Reference numerals 3 and 45 are drive motors.

Next, the configurations of the first and second rooting material detectors 15 and 17 will be described. As shown in FIGS. 2 to 4, the first rooting material detection unit 15 and the second rooting material detection unit 17 connect one log 9 supplied from the log separating mechanism 13 in the axial direction of the log 9. It is configured as a conveyor for transporting. Then, as described above, the tying material detection mechanism 19 for detecting the tying of the log 9 is arranged near the outlet of the first tying material detection unit 15. As shown in FIG. 8, the rooting material detection mechanism 19 uses an optical sensor, and measures the outer diameter of the log 9 from two directions orthogonal to each other, and the log 9 is the root. It is to determine whether the material is upholstery. First, there are light projecting units 47, 47, and light receiving units 49, 49 are arranged so as to face the light projecting units 47, 47, respectively. The outside diameter is intermittently measured by the rooting material detection mechanism 19 having such a configuration, and if the measured value fluctuates by a value exceeding a predetermined set value, this is fixed. It will be determined as a material.

Here, the rooting of the log 9 will be described. In the case of the arrangement example shown in FIG. 1, the first rooting material detecting section 1 is used.
In the log 9 from 5 to the second rooting material detection unit 17,
If the tip end side has a root, it is fed from the rear end when fed to the peeling device 1, so that the peeling device 1
There is no particular problem for the person, so it is sent as it is. On the other hand, in the log 9 from the first rooting material detection unit 15 to the second rooting material detection unit 17, when there is rooting on the rear end side, the peeling device 1
Since it is fed from the rear end when it is sent to, the peeling device 1 is particularly troubled, and therefore, in such a case, it is discharged.

As described above, the log 9 is detected during its conveyance from the first rooting material detecting unit 15 toward the second rooting material detecting unit 17, and the rooting is detected. The log 9 that has finished the procedure is used as it is for the second rooting material detection unit 17
Will be transported to the side. The log 9 conveyed to the second rooting material detection unit 17 side is discharged downward in FIG. 1 when it is the rooting material (when there is rooting at the rear end), and when it is not the case. Is transported to the upper side of the log stock mechanism 21 in FIG. The distribution mechanism 51 shown in FIGS. 5 to 7 realizes this. The distribution mechanism 51 is installed at two positions in the axial direction in the second rooting member detection unit 17. That is, there is a rotatable arm portion 53,
This arm portion 53 is moved to the position shown in FIG.
Rotate appropriately in the left and right directions. When the log 9 is a lining material, the arm portion 53 is rotated counterclockwise in FIG. 7, whereby the log 9 placed on the arm 53 is discharged to the left side in FIG. 7. . On the other hand, when the log 9 is not the lining material, the arm portion 53 is rotated clockwise in FIG. 7, whereby the log 9 placed thereon is arranged on the right side in FIG. The log is transported to the log stock mechanism 21 side.

The log stock mechanism 21 is constructed as a conveyor mechanism as shown in FIG. That is,
There are rotating bodies 57, 57, and an endless body 59 is wound around these rotating bodies 57, 57. The endless member 59 has a plurality of receiving members 61, and the logs 9 are supplied to the log feeding conveyor 5 side of the peeling device 1 while being supported by the receiving members 61. Also, the second
In the rooting material detection unit 17, as shown in FIG. 1, the rear end of the log 9 is detected by the first log rear end detection mechanism 63, at which point the transportation of the log 9 is stopped and the log 9 is positioned. I'm trying to do. The log 9 thus positioned is conveyed as it is to the log stock mechanism 21 side, and then transferred to the log feeding conveyor mechanism 5 side of the peeling apparatus 1.

Also in the log feeding conveyor mechanism 5 of the peeling device 1, the rear end of the log 9 is detected by the second log rear end detecting mechanism 65. In this case, the timing for receiving the next log 9 is determined, and when the second log trailing end detection mechanism 65 detects the trailing end of the log 9, the log stock mechanism 21 is driven,
The next log 9 is the log feeding conveyor mechanism 5 of the peeling device 1.
Transfer to the side. Further, the timing of the transportation of the logs 9 from the first rooting material detection unit 15 to the second rooting material detection unit 17 side is to be carried out sequentially at the timing when the operation of the distribution mechanism 51 is completed. ing. It should be noted that how to take these timings and which signal is used to perform them may be set arbitrarily. Also, at the timing of turning on / off the log separating mechanism 13, when the log 9 is present at the log receiving position of the first rooting material detecting unit 15, the log separating mechanism 13 is stopped and is in a standby state. . The standby state is a state in which one log 9 is positioned at the tip thereof, which is detected by a sensor (not shown) of the log separating mechanism 13. Then, after confirming that there is no log 9 at the log receiving position of the first rooting material detection unit 15 (for example, by a sensor not shown), one log 9 is supplied to the first rooting material detection unit 15. . When the log 9 is directly transferred to the log feeding conveyor 5 side of the peeling device 1 by using the bypass mechanism 23, it is possible to detect whether or not the log 9 is present at the log receiving position of the log feeding conveyor 5. The log separation mechanism 13 is controlled to be turned on / off.

Next, regarding the structure of the bypass mechanism 23,
This will be described with reference to FIGS. 4 and 5. First, there is a conveyor mechanism 67, and the conveyor mechanism 67 includes the first rotating body 6
9, a second rotating body 71, and an endless body 73 wound around the first rotating body 69 and the second rotating body 71. The rotation is transmitted from the drive motor 75 to the first rotating body 69 via the rotation transmitting mechanism 77. The entire conveyor mechanism 67 is rotated by the cylinder mechanism 79. Then, in the case of the log 9 which does not require the detection of the rooting material, the conveyor mechanism 67 is brought into the state shown by the phantom line in FIG. 4, and the log 9 from the log separating mechanism 13 is transferred to the peeling device 1 side as it is. On the other hand, in the case of the log 9 that needs the rooting material detection, the conveyor mechanism 67 is set to the state shown by the solid line in FIG. 4, and the log 9 from the log separating mechanism 13 is set to the first rooting material detection unit. It is allowed to transfer to the 15 side.

As described above, according to this embodiment, the following effects can be obtained. First, on the primary side of the peeling device 1, it is determined whether or not the log 9 is a rooting material, and if there is a possibility that the log 9 will be supplied to the peeling part 3 of the peeling device 1 from the original mouth side with the rooting. Since this is eliminated in advance, it is possible to prevent occurrence of various problems due to rooting. Also, for the logs 9 that have been eliminated, since this is inverted by 180 ° and then input again,
A desired peeling treatment can be applied to them as well.
Further, since the log stocking mechanism 21 is arranged, a certain amount of logs 9 can be stocked there, and therefore, it is assumed that several logs 9 will all interfere with the peeling part 3. Even if it is excluded as a material, the operation rate on the peeling device 1 side does not decrease. Further, since the bypass means 23 is provided, for example,
When the log 9 does not need to detect the tension, for example, if it has a relatively small diameter, it can be transferred as it is to the peeling device 1 side, and efficient lumbering can be realized. Further, since the optical sensor is used to measure the outer diameter of the log 9 from all directions when detecting the root, it is possible to perform a more accurate process.

Next, a second embodiment will be described with reference to FIGS. 8 and 9. That is, in the case of the first embodiment, the primary side of the peeling device detects the rooting material and eliminates it. However, in this embodiment, the rooting material is detected. Accordingly, the operations of the peeling device 1 and the transport mechanism in front of the peeling device 1 are controlled to prevent the occurrence of troubles due to rooting. First, in front of the peeling unit 3 of the peeling device 1, a transport mechanism 81 that supports the log 9 from below and transports it, and a pressing mechanism 83 that presses the log 9 from above are installed. The transport mechanism 81 is composed of rotating bodies 85 and 85, an endless body 87 wound around these rotating bodies 85 and 85, and a drive motor 89 that drives the endless body 87. In addition, the pressing mechanism 83 includes the rotating body 9
1, 91, a cylinder mechanism 93, and a drive motor (not shown). The means for detecting the outer diameter of the log 9 is the same as in the case of the first embodiment.

First, the tip of the log 9 is detected by the sensor 95, and the outside diameter of the log 9 is measured by the rooting material detecting mechanism 19 at that time. The measured value at this time is the first memory 9
9, stored in the second memory 101. Next, the tip of the log 9 is detected by the sensor 97, and at that time, the outer diameter of the log 9 is measured again by the rooting material detection mechanism 19. This measured value is stored in the third memory 103 and the fourth memory 105. The outer diameter is measured separately in the X direction and the Y direction. Next, the first comparing means 107 and the second comparing means 109.
The difference between the first outer diameter and the second outer diameter is calculated by. Then, it is determined whether the difference is less than or equal to a preset set value or exceeds the preset value by the first determination unit 111 and the second determination unit 111.
The determination means 113 determines. Then, the third discriminating means 115 is further provided to the first discriminating means 111 and the second discriminating means 111.
If at least one of the determination results of the determination means 113 exceeds the set value, the log 9 is determined to be a rooting material. Note that reference numerals 117 and 119 in the figure denote first display means and second display means for digitally displaying the respective measurement results. Explaining the display by the first display means 117 and the second display means 119, for example, the light receiving portions 49, 49
If the photocell is composed of a plurality of photocells, only the part of the phototube outside the outer diameter part of the log 9 will receive light, whereby the shadow part, that is, the length of the outer diameter part of the log 9, will be It is automatically calculated from the number of photocells in the area not receiving light, which is, for example, in units of mm, the first display means 1 described above.
17 and the second display means 119 respectively.

Next, how to control the pressing mechanism 83 and the cutter portion 3b of the peeling portion 3 when the log 9 is the lining material and when it is not the lining material will be described.
When the log 9 is not the lining material, the pressing mechanism 83 starts pressing when the log 9 is conveyed by the distance (L ₁ ) after the tip of the log 9 is detected by the sensor 95.
The distance is calculated based on the signal from the encoder 90. Further, after the tip of the log 9 is detected by the sensor 95, the cutter portion 3b is closed when it is conveyed by the distance (L ₂ ) (shown by the solid line in FIG. 9). The distance is detected by the first counter 121 and the second counter 123.
The control signals to the pressing mechanism 83 and the cutter unit 3b are output from the first switching circuit 125 and the second switching circuit 127.

On the other hand, when the log 9 is a lining material, when the tip of the log 9 is detected by the sensor 95 and then the pressing mechanism 83 is carried by the distance (L ₁ + L ₁ ′). Start pressing by. Also, after the tip of the log 9 is detected by the sensor 95, the distance (L ₂ + L ₂ ')
After being conveyed, the cutter unit 3b is closed.
The distance is detected by the first counter 121, the second counter 123, the third counter 129, and the fourth counter 131, and the control signals to the pressing mechanism 83 and the cutter unit 3b are the first switching circuit 125 and the first switching circuit 125. It is output from the 2-switching circuit 127. That is, after the root portion of the log 9 has passed, it is pressed by the pressing mechanism 83 or is gripped by the cutter portion 3b (shown by a virtual line in FIG. 9). This prevents the occurrence of defects due to rooting.

Next, a third embodiment will be described with reference to FIG. In this case, the mechanical touch sensor 141 is arranged in a cantilever manner as the rooting material detection mechanism 19. Further, in the case of the fourth embodiment shown in FIG. 11, the mechanical first touch sensor 143 and the second mechanical touch sensor 145 are similarly arranged on the left and right sides of the log 9.
