DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic long wood supply apparatus.

[0002]

2. Description of the Related Art Conventionally, after a high-quality thin veneer is adhered to the surface of long wood, a plurality of steps are performed, such as cutting off the ears of the side edge of the adhered thin veneer. In the case of processing, after transporting long wood in the longitudinal direction, it may be necessary to carry it out in the lateral direction (side direction) and further in the longitudinal direction.

More specifically, when the long wood W is automatically transported as described above, as shown in FIG. 13, the long wood W carried in the longitudinal direction is temporarily moved in the lateral direction (side direction). On the transfer belts 2a, 2b for
By driving the b simultaneously, it is conveyed in the lateral direction, hits the stopper 1 and is aligned at a predetermined position, and is then conveyed in the longitudinal direction by the convey roller 3 which rises relatively.

[0004]

However, in the automatic feeding device, for example, the long wood Wa is transported by the conveyor belt 2.
a, 2b, when supplied obliquely, this long wood Wa
First hits the stopper 1a, and the movement of this portion is prevented. The transport belts 2a and 2b carry out a transport operation until the long wood Wa hits the stopper 1d to correct the inclination, while the next long wood Wb is moving. That is, since the two conveyor belts 2a and 2b remain driven, even if the interval between the long woods Wa and Wb is L1 at first, the tip of the long wood Wa hits the stopper 1a to prevent the movement thereof. The long wood Wb has moved by a distance L2 until the rear end portion hits the stopper 1d. Therefore, the interval between the long lumber Wa and Wb is reduced from L1 at first to L3 (L1-L2).

Therefore, when the initial dimension L1 is small, or when L1 is reduced due to several inclination corrections, when the long wood Wa is placed on the carry-out roller 3, one piece of the long wood Wb Part is also placed on the carry-out roller 3,
A situation occurs in which only the long wood Wa cannot be carried out. In this case, it is necessary to adjust the transport time of the long wood W in the lateral direction or to adjust the position manually, which causes deterioration in workability in each step.

Accordingly, an object of the present invention is to provide an automatic long-timber supply device that can be efficiently transported.

[0007] In order to achieve the above object, the present invention provides a side transport section for transporting long timber in a side direction orthogonal to the longitudinal direction and positioning the long timber at a carry-out position; In the automatic feeding device for long timber, which is automatically supplied by a longitudinal unloading unit for unloading in the longitudinal direction, the lateral transport unit supports the long timber at at least two positions on both ends, and independently. A plurality of lateral transfer devices provided so as to be driven, and a plurality of position detection sensors are arranged at the carry-out position on the same straight line parallel to the longitudinal carry-out portion, corresponding to the lateral transfer device. Then, based on a detection signal output by any of the position detection sensors detecting long timber, sequentially stop the lateral conveyance device corresponding to the sensor to align the long timber at the unloading position. And then the longitudinal unloading section It is provided with a control unit for outputting a control signal to be driven.

[0008] In order to achieve the above object, the present invention also provides a side transport section for transporting a long piece of wood in a side direction perpendicular to the longitudinal direction and positioning the piece at a carry-out position; In the automatic feeding device for long timber, which is configured to automatically supply the timber with a longitudinal unloading unit that unloads the timber in the longitudinal direction, the lateral transport unit supports the long timber at at least two locations on both ends, and is independent. A plurality of lateral transfer devices provided so as to be driven, and a plurality of position detection sensors, corresponding to the lateral transfer device, at a discharge preparation position on the upstream side of the discharge position. If there is a long piece of timber at the unloading position, it is output by detecting one of the next long pieces of timber at the unloading preparation position. Based on the detected signal By sequentially stopping the lateral transfer devices corresponding to, the long timber is aligned with the unloading preparation position, the longitudinal unloading unit is driven to unload the long timber at the unloading position, and the all-side transfer is performed. A control device is provided for outputting a control signal for driving the longitudinal discharge portion again after restarting the driving of the device and aligning it at the discharge position.

Further, in order to achieve the above object, the present invention provides a side transport section for transporting a long piece of wood in a side direction orthogonal to the longitudinal direction and positioning the piece at a carry-out position; In the automatic supply device for long timber, which is configured to automatically supply the timber with a longitudinal discharge unit that conveys the lumber in the longitudinal direction, the longitudinal discharge unit is vertically movable and freely movable in the lateral direction, and is controlled by the lateral transport unit. An edge detection sensor, which is located in the transport area of the long piece of timber conveyed in the lateral direction and detects the side edge of the long piece of timber, is provided in the longitudinal discharge section. By moving the direction discharge section in the lateral direction, in the discharge area of the longitudinal direction discharge section, the side edge on the side upstream side substantially coincides with the side edge on the side upstream side of the long wood. , Elevating the longitudinal discharge section After holding the, it is provided with a control unit for outputting a control signal for driving the longitudinal unloading unit.

According to the automatic feeding device having the above structure, when the longitudinal discharge portion is moved and stopped when the edge detection sensor detects the side edge portion of the long timber on the upstream side in the lateral direction, the longitudinal discharge portion is stopped. A side edge of the carry-out area on the upstream side in the lateral direction substantially coincides with a side edge of the long wood on the upstream side in the lateral direction. Therefore, when the longitudinal discharge portion is raised, the longitudinal discharge portion holds the long timber without hardly protruding from the side edge on the upstream side in the lateral direction. It is possible to carry out only the long timber located at the carry-out position without interference.

By detecting the distance from the next long piece of wood (the position of the next long piece of wood) by the edge detection sensor or another position detection sensor, the longitudinal discharge section is moved to the next long piece of wood. After being moved to a position where it does not interfere with the wood, it may be raised.

[0012] Further, in the automatic long-timber feeding apparatus having the above-mentioned configuration, a long-direction carry-in section for carrying the long timber in the longitudinal direction and stopping at a predetermined position according to the difference in the length is provided. The directional conveyance unit has side conveyance devices at a plurality of locations in accordance with long woods having different dimensions, and the control device is configured to control the side conveyance unit based on a position at which the long direction wood unit carries in the long wood. It is preferable to adopt a configuration for determining which one of the side transport devices is driven.

[0013] The longitudinal carry-in section may be composed of a plurality of independently driven rollers or belts juxtaposed in the longitudinal direction which is the carry-in direction of the long timber. Thereby, even if the intervals between the long timbers are different, the long timbers can be stopped in order from those transported to the regular position by the longitudinal loading section, and the transport by the lateral transport device can be performed reliably.

[0014] The automatic supply device may have, for example, a configuration having a plurality of position detection sensors juxtaposed in the longitudinal direction of long wood. This makes it possible to stop the driving of the longitudinal loading section based on the difference in the loading position and length of the long timber detected by each position detection sensor.

The drive motors 26a and 26b (see FIG. 6, only the drive motor 26a is shown in FIG. 3)
The support rollers 23 disposed on the lower surfaces of both end portions of the drive rollers and positioned on the upper surfaces thereof are rotated via the drive chains 31. The drive motor 26a rotates each support roller 23 of one block on the side of the veneer adhering device 11. On the other hand, the drive motor 26b rotates each of the support rollers 23 of the two blocks on the opposite side to the single-plate sticking device 11. The drive chain 3

The longitudinal carry-in section 17 is provided with a total of five sets of position detection sensors 17a to 17e, one set on each side.

[0027] As shown in FIG.
The side transport devices 33a, 33b,... Are arranged in four rows in a direction orthogonal to the direction in which the support rollers 23 of the longitudinal direction loading portion 17 are arranged.
33c and 33d are provided. Lateral transfer device 3
3a, 33b transports the shortest long lumber W1; lateral transport devices 33a, 33b, 33c transport normal-sized long lumber W2; and lateral transport devices 33a, 33b, 33.
The longest lumber W3 of c and 33d can be transported. Moreover, it is also possible to convey the shortest long wood W1 by each of the side direction conveying devices 33c and 33d. In this case, the movement control to the unloading position C, which will be described later, may be sequentially performed from those positioned at the unloading preparation position B.

And a chain 37. One of the sprockets 36 is rotated by driving a motor 38 (see FIGS. 5 and 6). A plurality of support plates 39 (see FIG. 6) are continuously attached to the chain 37, and the long wood W
Is to be placed.

As shown in FIGS. 5 and 6, the longitudinal discharge section 19 is composed of a plurality of discharge rollers 41 juxtaposed at a predetermined interval in a direction orthogonal to the direction of conveyance by the side conveyance section 18. The carry-out roller 41 has both ends rotatably connected to one end of a substantially L-shaped arm 42. An intermediate portion of the arm 42 is rotatably mounted on a gantry 43 around a support shaft 42b, and a lower end thereof is rotatably connected to a slider 43a that moves on the gantry 43 by a cylinder 44. Therefore, the cylinder 44
Is driven, the slider 43a slides via the rod 44a, and moves the arm 42 about the support shaft 42b to move up and down the carry-out roller 41. The lifting position of the carry-out roller 41 is the vertical position above the support plate 39 as a boundary. The gantry 43 is reciprocally movable in a lateral direction on a rail 21b provided on the upper surface of the base 21, and reciprocates via a chain 43d by driving a motor 43c.

Further, the base 43 of the longitudinal discharge portion 19
Are provided with position detection sensors 40a and 40b and an edge detection sensor 40c, respectively. Sensor 40a
Is the side transport device 33 in front of the unloading position C described below.
In the vicinity of b and 33c, they are arranged at a deceleration position A on the same straight line. The sensor 40b includes the unloading position C and the sensor 4
In the interval 0a, one for each of the lateral conveyance devices 33a, 33b, 33c, 33d is disposed at the unloading preparation position B on the same straight line. Edge detection sensor 40c
Denotes a pair of photosensors arranged at predetermined intervals in the lateral direction, each being provided on the same straight line between the carry-out position C and the sensor 40b. Each sensor 40c outputs an ON signal when there is no long timber W at the opposing position, and outputs an OFF signal when there is no long wood W. Therefore, if one sensor 40c (the left side in FIG. 6) outputs an ON signal and the other sensor 40c (the right side in FIG. 6) outputs an OFF signal, the long timber W is placed between the two sensors 40c. The presence of the (right) side edge can be detected. In addition,
Both the sensor 40c and the carry-out roller 41
At the time when the (right) side edge of the
When the is moved upward, the edge is in a positional relationship that substantially coincides with the side edge of the long piece of wood W. In addition, at the unloading position C on the same straight line perpendicular to the transport direction, the position detection sensor 21a (see FIG. 1) is provided on the base 21 for each of the pair of lateral transport devices 33a, 33b and 33c, 33d. 6) is provided.

The control device 20 includes the position detecting sensors 17a to 17a.
17e, 40a, 40b, the drive motors 26a, 26b,
The drive control of the air cylinder 29, the cylinder 44 and the like is performed.

Next, the operation of the automatic supply device will be described with reference to the flowcharts of FIGS. In the present embodiment, the automatic transport control of the long lumber W is performed by a loading process (step S1) and a lateral transport process (step S1) shown in FIG.
2) and carry-out processing (step S3).

First, the loading process will be described.

In the loading process, as shown in FIGS. 8 and 9, once the veneer is pasted on the long wood W by the veneer pasting device 11, the previous process is completed (step S11). Then, the cylinder 29 of the longitudinal loading section 17 is driven to move the loading roller 23 above the side transport section 18 via the gantry 22 (step S12). Then, the carry-in belt 16 and both drive motors 26a and 26b are driven (step S13), and the long wood W is moved in the longitudinal direction by the carry-in belt 16 and then by the belt 25b.

Next, if the sensor 17b detects the front end of the long wood W (step S14), it is determined whether the sensor 17a has detected the rear end (step S15). At this time, if the sensor 17a does not detect the long timber W, it is determined that the long timber W1 is the shortest, and if the sensor 17a has detected, it is determined that the long timber W2 or W3 has another dimension. .

If it is determined that it is the long timber W1, it is determined whether it is the first long timber W1 (step S).
16). For example, the determination may be made based on whether the detection by the sensor 17a within the predetermined time is the first time or the second time. If it is the first line, the sensor 17e detects the front end (step S1).
7) If the sensor 17c has not detected the rear end (step S18), the drive motor 26b is stopped (step S19). As a result, the long wood W1 can be transported by the lateral transport devices 33c and 33d.

Since the next long piece of wood W1 is determined to be the second piece in step S17, the sensor 17b
Detects the front end (step S14), and if the sensor 17a does not detect the rear end (step S15), stops the drive motor 26a (step S20). As a result, the next long lumber W1 is transferred to the side transport devices 33a, 33a.
It becomes possible to carry at b.

As described above, when the object to be conveyed is long timber W1 having a small size, the first long timber W1 and the next long timber W1 are separated by the drive motors 26a and 26b which are driven independently. Even if the interval is not constant, each long wood W1
Can be accurately positioned so that they can be transported by the lateral transport devices 33a, 33b or 33c, 33d, respectively.

On the other hand, in step S15, the long timber W
If it is determined that it is 2 or W3, at the time when the sensor 17c detects (step S21), it is determined whether or not the sensor 17a detects (step S22). If it has not been detected, it is determined to be long wood W2, and if it has been detected, it is determined to be long wood W3.

If it is determined that the piece is long wood W2, both drive motors 26a and 26b are stopped (step S23), and can be transported by the lateral transport devices 33a, 33b and 33c. If it is determined that the piece is long wood W3, the sensor 1
7e detects (step S24), and if the sensor 17a does not detect (step S25), the two drive motors 26
a, 26b are stopped (step S23), and the transfer can be performed by the side transfer devices 33a, 33b, 33c, 33d.

Next, the side-direction transport process will be described.

In the lateral conveyance process, as shown in FIGS. 10 and 11, the cylinder 29 is driven to lower the carry-in roller 23 via the gantry 22 (step S31), and the long wood W is laterally conveyed. It is placed on the upper surface of the support plate 39 of the device 33. Therefore, the corresponding motor 38 is driven based on the estimation result in step S18 (step S32), and the transport of the long wood W to the side is started.

When the sensor 40a detects the side edge of the long piece of wood W in the transport direction (step S33), the corresponding side transport device 33 is sequentially decelerated (steps S34 and S35). Thereafter, it is determined whether or not the sensor 21a has detected the side edge of the long piece of wood W in the transport direction (step S36).

If the sensor 21a has not detected the side edge of the long piece of wood W in the transport direction, it is determined that there is no long piece of wood W being unloaded in the longitudinal direction at that time, and the transport in the side direction is performed. continue. Then, when the sensor 21a detects the side edge of the long piece of wood W in the transport direction (step S37), the corresponding lateral transport device 33 is sequentially stopped (steps S38 and S39). In this case, since one sensor 21a is provided for each of the pair of lateral transport devices 33a, 33b and 33c, 33d, one of the sensors 21a is provided at the side edge of the long wood W in the transport direction. Is detected, the corresponding lateral transport device 33a, 33b or 33
c and 33d are stopped. Thereby, the interval between the long woods W is not reduced in the transport path in the lateral transport devices 33a, 33b or 33c, 33d.

On the other hand, if the long wood W is detected by the sensor 21a, it cannot be directly conveyed to the carry-out position C. Therefore, when the sensor 40b detects the long wood W (step S40), the corresponding side-direction conveyance devices 33 are sequentially turned on. Stops (step S41,
S42), the long wood W is positioned at the unloading preparation position B. That is, the sensor 40b is connected to the
a, 33b, 33c, and 33d, respectively, so that if any one of the sensors 40b detects the long wood W, the corresponding lateral transport device 33a,
33b, 33c or 33d is stopped (because the long wood W is rod-shaped, it is actually sequentially detected from one of the sensors 40b located at both ends). afterwards,
The omnidirectional conveyance devices 33 are simultaneously driven (step S4).
3) The long wood W is moved to the unloading position C.

According to this, even if the long timber W is being unloaded in the longitudinal direction, the next long timber W can be aligned at the unloading preparation position B close to the unloading position C. Efficient.

As described above, when the next long timber W is to be aligned at the unloading preparation position B, if the long timber W1 is used, each side direction transfer device 33 corresponding to each sensor 40b.
a, 33b or 33c, 33d as one unit, and the lateral transport devices 33a, 33b, 33c, or 33d are sequentially stopped. However, in the case of long wood W2 or W3, the lateral transport devices 33a, 33b, 33c or 33a, 33b, 3
3c and 33d may be stopped as one unit.

When the long lumber W is positioned at the carry-out position C in this way, first, it is determined whether the ON signal from the sensor 40c is 0, 1, or 2 (step S44). S45). That is, when the long wood W is located at any opposing position of the pair of sensors 40c arranged side by side, the ON signal becomes 0, and FIG.
When the long timber W is located only at the corresponding position of the middle left sensor 40c, the ON signal is 1, and when the long timber W is not located at any opposing position, the ON signal is 2
Becomes

Therefore, when the number of ON signals is 2 (pieces),
Since it is determined that the upper part of the sensor 40c is completely covered with the long wood W, the gantry 43 is moved to the right in FIG. 6 (step S46). If the ON signal is 0 (number), it is determined that there is no long wood W above the sensor 40c, and the gantry 43 is moved to the left side in FIG. 6 (step S47). After that, the ON signal becomes 1
If the number of pieces is (pieces), the long wood W is positioned only above one sensor 40c (right side in FIG. 6), and the (right) side edge of the long wood W is positioned between the two sensors 40c. Since it has been detected, the movement of the gantry 43 is stopped (step S
48). Thereby, as shown in FIG. 6, the position of the edge of the ascending and descending discharge roller 41 of the longitudinal direction discharge portion 19 and the edge of the long wood W detected by the sensor 40c substantially coincide with each other in the side direction. It becomes possible.

Finally, the unloading process will be described.

In the unloading process, as shown in FIG. 12, the unloading roller 41 is moved upward (step S51), and a long piece of wood W is placed thereon. In this case, based on the detection signal of the sensor 40c, as described above, the position of the side edge of the long wood W and the position of the edge of the carry-out roller 41 can be substantially matched in the side direction. The unloading roller 41 does not interfere with the next long wood W. And the unloading roller 4
By driving 1 (step S52), the long wood W is carried out to the ear catching device 13.

[0052]

As is apparent from the above description, according to the automatic long wood supply apparatus of the present invention, the position detection sensor detects the long wood, and the corresponding side-to-side transport device is sequentially operated. Since it is stopped, the distance from the long timber W located on the upstream side of the transport path corresponding to each lateral direction transport device is not reduced, and a constant interval is maintained. Therefore, complicated adjustment work as in the related art is not required, and efficient conveyance becomes possible.

Further, by moving the longitudinal discharge section based on the detection signal from the edge detection sensor, the side edge portion on the upstream side in the lateral direction and the side of the long wood in the discharge area of the longitudinal discharge section. The long timber is held at the position where the side edge on the upstream side almost coincides, so that the longitudinal unloading section does not interfere with the next long timber and ensures reliable transport. Can be.
