Description

[0001]
[Industrial application fields]
The present invention provides a method and apparatus for smoothly and accurately dropping and depositing a plate-like body such as a veneer veneer, a plywood, a synthetic resin plate, etc., which is conveyed on a conveyor at a high speed from the previous step, above a deposition position. It is about.
[0002]
[Prior art]
Conventionally, a conveyor that can expand and contract toward the upper side of the stacking position of the plate-shaped body is provided, and the plate-shaped body is dropped to the stacking position when the expandable conveyor is extended while the plate-shaped body is placed and contracted. Methods are known.
[0003]
However, when the plate-like body is dropped from the stretched conveyor to the deposition position and dropped to the deposition position, it may not be able to accurately deposit at the deposition position due to the distance until it falls, the plate-like body rising due to negative pressure, etc. . For this reason, variation occurs in the accumulation state of the plate-like body, resulting in an obstacle to the taking-out operation in the next stage.
[0004]
[Problems to be solved by the invention]
In particular, the veneer veneer that is deposited includes a random veneer that does not have a predetermined length with respect to the transport direction even though it has a length in a direction that intersects the transport direction. This irregular single plate is used as a so-called repair single plate, and the length in the conveying direction is not constant but is indefinite and varies. This irregular single plate is usually conveyed in a mixed state with a regular veneer single plate having a predetermined length, and is deposited in a deposition box installed at each deposition position.
[0005]
As described above, since the length in the transport direction is not constant as described above, it is impossible to deposit this irregular single plate in a dedicated deposition box having a constant length in the transport direction. In other words, even if the length of the irregular single plate is the longest in the conveyance direction, it does not reach the predetermined length, and the length is unspecified, so that it cannot be deposited in a specific dedicated deposition box. For this reason, in the actual state of work, the same accumulation box as a regular veneer veneer having a predetermined length is used. For example, when depositing the irregular veneer sequentially with the front end side in the transport direction of the deposition box as the deposition reference, the front end portion of the deposition box is filled with the irregular veneer, but the space part is extended to this rear end portion. Deposition in a noticeable distorted state.
[0006]
If the deposition in the distorted state continues and the balance between the front end filling portion and the rear end space portion is lost, the deposition failure of the once-deposited random plate occurs. Therefore, despite the fact that there is still room for deposition in the random-sized single-plate stacking box, in the actual work, the stacking height is about half the height of the stacking box before the above-mentioned deposition collapse occurs. When the time reaches, the deposition box is replaced.
[0007]
[Means for Solving the Problems and Effects of the Invention]
  In order to solve the above problems, the plate-like body of the present invention is deposited.Device configurationIs
  A pair of fixed pulleys supported at a fixed interval before and after the machine frame, a movable frame that is movable forward and backward with respect to the deposition position of the plate-like body located in front, with the upper part of the machine frame as a guide, A pair of front and rear movable pulleys supported at an arbitrary interval on the movable frame, a belt rotating prime mover for driving a belt wound endlessly while being folded back between the pulleys, and the movable movable forward and backward. A movable frame advancing and retracting motor that moves the frame between the forward position and the backward position;
The belt wound between the pulleys driven by the belt rotating prime mover constitutes an extendable conveyor that conveys the plate-like body on the movable frame, and the plate conveyed by the extendable conveyor moved to the advance position. A plate-like body depositing device that leaves the plate-like body, the telescopic conveyor moves from the advance position to the retreat position, and drops the plate-like body onto the lifting platform at the deposition position;
A plate-like body that is placed on the telescopic conveyor and conveyed to the deposition position,A downstream stop position where the front end portion of the plate-like body is the stop position regulating side downstream of the deposition position, and an upstream stop position where the rear end portion of the plate-like body is the stop position regulating side upstream of the deposition position 2 stop positionsPosition control system that controls the position by selecting eitherWithThe position control system includes a detector that detects the passage of the transported plate-like body, and a controller that controls the belt rotating prime mover and the movable frame advance / retreat prime mover. A selection command device is connected to select one of two stop positions, a downstream stop position and an upstream stop position, as the body deposition position,
The controller stops the telescopic conveyor at the stop position selected by the selection commander based on the signal of the plate detected by the detector, and conveys the plate up above the deposition position. The belt rotating prime mover is decelerated and stopped just before the deposition position, and then the movable frame advance / retreat prime mover is driven to move the movable frame to the retracted position, and the plate loaded on the lifting platform A height control detector in which the upper surface of the plate-like body is always constant, the telescopic conveyor is installed in a descending gradient with the plate-like body stacking position side being low, and the plate-like body is approaching the lifting platform on the tip side Falling toward the elevator with the height controlled to a certain levelIt is characterized by that.
[0008]
The telescopic conveyor can be expanded and contracted to a plate-like body deposition position using a machine frame installed in a pair of left and right in the conveying direction of the plate-like body as a guide. That is, a slide rail or a linear way is laid on the upper surface of the machine frame, and a linear block is attached on each moving member. The movable frame is attached in a cantilever manner by connecting the front and rear portions of this linear block. The plate-like body transport surface of the telescopic conveyor may be installed in a substantially horizontal state to move forward and backward, but is preferably installed in a downward gradient toward the plate-like body deposition position. In this way, if the plate-like body transport surface of the telescopic conveyor is inclined downward in the transport direction, the movable frame portion is separated from the plate-like body deposition position by the lifting angle corresponding to the gradient when the telescopic conveyor is retracted. . Therefore, even if the plate-like body immediately after deposition is soared, bent, twisted, warped, particularly warped upward, contact between the rear end portion of the plate-like body and the retractable telescopic conveyor is avoided. The Therefore, the height of the upper surface on which the plate-like body is deposited can be as close as possible to the conveying surface of the telescopic conveyor, and the deposition cycle can be shortened by reducing the fall distance of the plate-like body.
[0009]
Then, the plate-like body conveyed by the telescopic conveyor is once decelerated immediately before being deposited on either the downstream stop position or the upstream stop position. The plate-like body is selected and deposited at either the downstream stop position or the upstream stop position, and the order, stop position, and number of times are arbitrary. For example, an arbitrary number of plates are continuously deposited on the downstream stop position where the front end side of the deposition position is the stop position, and then the plate is continuously connected to the upstream stop position where the rear end side of the deposition position is the stop position. It is also optional to deposit an arbitrary number of sheets. Preferably, the plate-like body is alternately deposited on the downstream stop position side and the upstream stop position side. Therefore, even if the plate has a length in the direction intersecting the conveyance direction, a plate-like body that does not have a predetermined length with respect to the conveyance direction can maintain a deposition balance.
[0010]
The plate-like body may be transferred manually onto the telescopic conveyor, but is usually transferred from the preceding stage via, for example, a relay conveyor. Next, when the pair of left and right belt conveyors are rotated at a high speed, the plate-like body is conveyed forward. That is, when the movable frame is advanced from the retracted limit position on the moving member laid on the machine frame via the linear block, the front and rear movable pulleys supported in a pair of front and rear maintain the distance, and the belt It moves rapidly while maintaining tension. Then, the movable frame is stopped while decelerating immediately above the position where the plate-like body is deposited, that is, before the telescopic conveyor reaches its forward limit position. At this time, the plate-like body placed on the telescopic conveyor is restrained at its front by the restraining body and is prohibited from moving in the transport direction. This constrained part may be one place at the front end of the plate-like body or a plurality of places at arbitrary intervals in the direction intersecting the transport direction. This constraining body is preferably in a state of being sandwiched from the thickness direction of the plate-shaped body, that is, from the vertical direction thereof.
[0013]
  The deposition position of the plate-like body is selected from either a downstream stop position or an upstream stop positionPosition control system,Based on the detection command of the detector that detects the passage of the plate-like body, the controller sets the speed of the telescopic conveyor to a deceleration state, and then stops the telescopic conveyor. A selection command unit is connected to the controller, and the plate-like body is selected and distributed to one of two stop positions, a downstream stop position and an upstream stop position. This detector may be either a limit switch for detecting a plate-like body that is placed on a telescopic conveyor and conveyed to the deposition position, or a non-contact type such as a transmission type or a reflection type photoelectric tube. It is sufficient to detect that the front end or rear end of the body has passed.
[0014]
And when detecting the front end part of the plate-shaped body placed on the stretchable conveyor by the detector, the drive speed of the stretchable conveyor is reduced by an arbitrary time via a delay circuit such as a timer, and then the stretchable conveyor is Stop. The plate-like body can be deposited at either the downstream stop position or the upstream stop position of the deposition position by detecting the passage by a single detector. Further, there may be a case where a plurality of detectors, for example, two detectors are installed at a certain interval in a direction crossing the transport direction to detect a plate-like body. This is because, if the plate-like body is a veneer single plate, the presence of the plate-like body cannot be confirmed due to defects inherent in the plate-like body itself, such as node holes, tears, and cracks, mainly to prevent false detection. belongs to.
[0015]
Further, the detector is installed at a position separated from the deposition position, and detects the front end and the rear end of the plate-like body that is placed on the telescopic conveyor and conveyed. Then, when the position to be deposited is instructed by the selection commander as the upstream stop position, the driving speed is set via a delay circuit such as a timer after the telescopic conveyor moves forward by a predetermined distance based on this front end detection signal. After decelerating for an arbitrary time, the telescopic conveyor is stopped. In addition, when the position to be deposited is instructed to the upstream stop position from the selection commander, the drive speed is reduced by an arbitrary time via a delay circuit such as a timer based on the rear end detection signal, and then the telescopic conveyor Stop.
[0016]
For example, if the selection commander is used to alternately deposit and deposit the downstream stop position and the upstream stop position, when the front end of the plate body is detected by a single detector, the plate-like body is based on this detection signal. Deposit body to downstream stop position. Next, the detector outputs the rear end detection signal of this plate-like body and the front end detection signal of the next plate-like body to the controller, and these detection signals are received by the command from the selection commander in the controller. Not adopted. Then, the plate-like body is deposited at the upstream stop position by the rear-end detection signal output when the rear end of the next plate-like body is detected.
[0017]
Also, the detector can be installed exclusively for the case where the plate-like body is deposited at the downstream stop position and the case where the plate body is stopped at the upstream stop position. That is, a front end detector for depositing the plate-like body at the downstream stop position based on the detection signal of the front end portion of the plate-like body, and the upstream stop of the plate-like body based on the detection signal of the rear end portion of the plate-like body The detector for the rear end to be deposited at the position is installed, and the plate-like body to be deposited at the downstream stop position and the upstream stop position is detected by the dedicated detector. In this case, after detecting the plate-like body, the respective detectors are installed at positions separated by a predetermined distance for performing deceleration control of the driving speed of the telescopic conveyor. Preferably, the detector for the front end that detects the front end portion of the plate-like body is spaced above the deposition position, and the detector for the rear end that detects the rear end portion of the plate-like body is spaced behind the deposition position. Each of the telescopic conveyors is decelerated and controlled via a delay circuit, and deposited at a downstream stop position or an upstream stop position.
[0018]
Instead of the delay circuit described above, the following conveyance control can be performed. That is, it comprises a pulse transmitter installed on the telescopic conveyor, and a distance setting device for setting the distance from the detector position for the front end to the downstream stop position, and the distance from the detector position for the rear end to the upstream stop position. ing. Then, the telescopic conveyor is controlled to be decelerated based on the front end detection signal of the front end detector or the rear end detection signal of the rear end detector in the controller, and the pulse amount of the set distance is counted up. By stopping the telescopic conveyor. For convenience of control, it is preferable to set the predetermined distance from the front end detector to the downstream stop position and the rear end detector to the upstream stop position as the actual work.
[0019]
On the other hand, the telescopic conveyor supports a pair of fixed pulleys at regular intervals before and after the machine frame, and the movable frame that is movable forward and backward with respect to the deposition position of the plate-like body located in front by using the upper part of the machine frame as a guide. In addition, a pair of front and rear movable pulleys are supported by placing at least the length of the plate-like body to be accumulated, and the belt is wound endlessly between the pulleys.
[0020]
Machine frames constituting the telescopic conveyor are installed on both sides in the conveying direction of the plate-like body, and a rail running surface is provided on the upper surface via a moving member. The machine frame may be installed in a substantially horizontal state to move forward and backward, but is preferably installed in a downward gradient toward the direction of the plate-like body deposition position. In this way, if the plate-like body transport surface of the telescopic conveyor is inclined downward in the transport direction, the movable frame portion is separated from the plate-like body deposition position by the lifting angle corresponding to the gradient when the telescopic conveyor is retracted. .
[0026]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the telescopic conveyor used in the method of the present invention will be described.
A pair of shafts 2 and 3 are supported on the front and rear of the machine frame 1 so as to be orthogonal to the conveying direction, and front and rear fixed pulleys 4 and 5 are fixed to both ends of each shaft portion. Moving members 6 such as slide rails or linear ways as shown are laid on the upper surface of the machine frame 1, and linear blocks 7 moving on the moving members 6 are arranged at an arbitrary interval in the front and rear directions. The front and rear comrades of the linear block 7 are connected to each other via a connecting beam 8, and the rear part of the movable frame 9 is attached to the front and rear connecting beams 8, and the movable frame 9 is in a cantilever state. It can move back and forth along the moving member 6 as it is.
[0027]
A front movable pulley 10 is supported at the front part of the pair of movable frames 9, and a rear movable pulley 11 is placed at a certain distance from the front movable pulley 10 at the rear lower part of the front movable pulley 10. It is supported rotatably. The front and rear movable pulleys 10 and 11 are interposed between the fixed pulleys 4 and 5, that is, the front movable pulley 10 of the movable frame 9 and the rear movable movable frame 9 from the rear fixed pulley 5 of the machine frame 1. The pulley 11 is sequentially folded back to the front fixed pulley 4 of the machine frame 1, and the belt 12 is endlessly attached to the rear fixed pulley 5 of the machine frame 1 and is in a tensioned state via a balance weight, a tie pulley, etc. (not shown). A conveyor is configured by winding the sheet-like member 17, and the plate-like body 17 is conveyed by the conveyor.
[0028]
The rear shaft 3 around which the belt 12 is wound is connected to a motor 13 for rotating the belt via a chain wheel, and the driving, deceleration, and stop of the belt 12 are controlled by the control of the motor 13 for rotating the belt. . In addition, a drive shaft 14 driven by a motor 15 for moving the movable frame forward and backward is provided before and after the machine frame 1, and the movable frame 9 is attached to a chain wheel that interlocks the front and rear drive shafts 14. The advancing / retracting prime mover 15 rotates the drive shaft 14 at the rear via a chain wheel to control the advancing / retreating movement of the movable frame 9 along the moving member 6. Further, in front of the machine frame 1 and below the forward limit position of the movable frame 9, an elevating table 18 is provided that constitutes a deposition position of the plate-like body 17 for depositing the plate-like body 17 on the pallet. The elevator 18 is provided with a detector for detecting the height of the upper surface of the deposited plate-like body 17, and the elevator table so that the upper surface of the deposited plate-like body 17 is always constant according to the signal of the detector. 18 is height controlled. Since the movable frame 9 in FIGS. 1 to 3 is cantilevered, the plate-like body 17 conveyed on the conveyor is not limited in length perpendicular to the conveying direction.
[0029]
When the prime mover 15 for moving the movable frame back and forth is driven, the movable frame 9 located at the retreat limit moves forward on the moving member 6 via the linear block 7 while maintaining the cantilever state. Then, the front and rear movable pulleys 10 and 11 supported by the pair of front and rear are rapidly moved forward in the horizontal plane while maintaining the interval L and maintaining the tension state of the belt 12. Further, when the movable frame advancing / retracting prime mover 15 is driven in reverse from this state, the movable frame 9 located at the forward limit rapidly moves backward, so that the telescopic conveyor moves forward and backward above the deposition position of the plate-like body 17. 16 can be configured. Then, the plate-like body 17 conveyed on the telescopic conveyor 16 is dropped and deposited at the deposition position of the lower plate-like body 17 as the telescopic conveyor 16 advances and retreats.
[0030]
At a position corresponding to the forward limit of the telescopic conveyor 16, a restraining means 51 for restraining the front end portion of the transported plate-like body 17 is installed. A plurality of the restraining means 51 are arranged at a substantially central portion in the interval of the machine frame 1 extending in a pair on the left and right with respect to the transport direction or at an arbitrary interval in a direction crossing the transport direction. In FIG. 1, one restraining means 51 is installed at the central portion within the interval, and as shown in detail in FIG. 11, the base ends 54 and 55 of a pair of upper and lower clamping pieces 52 and 53 are sandwiched. Each of the cylinders 56 is pivotably attached. The pair of upper and lower sandwiching pieces 52 and 53 are in the form of leaf springs in order to increase the sandwiching force, and when the fluid cylinder 56 is operated, the front end portion of the plate-like body 17 located at the substantially central portion in the direction crossing the transport direction is The pair of sandwiching pieces 52 and 53 are sandwiched from above and below, and the sandwiching operation restrains the plate-like body 17 and prohibits the movement in the return direction accompanying the backward movement of the telescopic conveyor 16.
[0031]
Further, in order to drop and deposit the plate-like body 17, in addition to dropping due to its own weight, the front end portion may be forced down. In order to push down the plate-like body 17 to the elevator 18, it is sufficient to move the pair of upper and lower clamping pieces 52, 53 that restrain the front end in the vertical direction, but the following configuration is also possible. It is. As shown in FIG. 1, push-down means 61 that can protrude and retract with respect to the front end portion of the plate-like body 17 and can move up and down is installed at both end positions of a pair of upper and lower clamping pieces 52 and 53. The front end of the plate-like body 17 is brought into contact with the lifting platform 18 of the plate-like body 17 so as to be pushed down.
[0032]
Specifically, as shown in FIG. 12, the push-down means 61 has a vertically moving fluid cylinder 63 attached to a guide body 62 installed in the vertical direction, and a push-down body 65 is connected to the piston rod 64. The push-down body 65 can be moved up and down along the guide body 62 by supplying and discharging fluid to and from the cylinder chamber. On the other hand, the push-down body 65 is attached to the piston rod 67 of the fluid cylinder 66 that is attached to the tip of the piston rod 64 and moves up and down, and can protrude and immerse above the lifting platform 18. Then, the protrusion is held above the front end portion of the plate-like body 17 and is retracted from the front end portion of the plate-like body 17 so as to be immersed. In addition to the above-described fluid movement, the push-down body 65 is engaged with the pinion gear by rotating the pinion gear by rotating the pinion gear with the crank movement or the rack gear laid in the vertical direction. It is also possible to move 65 up and down and move up and down. Then, while retracting the telescopic conveyor 16, the push-down body 65 advances above the plate-like body 17, and if the push-down body 65 of the push-down means 61 descends while opening the holding pieces 52, 53, the plate-like body 17 Can be correctly dropped onto the lift 18 which is the deposition position.
[0033]
Furthermore, as shown in FIG. 13, in order to push down the front end of the plate-like body 17, in addition to the above-described protrusion / displacement movement and vertical movement, it is also possible to use a turning movement that is a combined trajectory. That is, the shaft 68 is provided on an extension line of the plate-like body 17 in the transport direction, and the push-down body 65 attached to the shaft 68 can rotate at least a certain angle around the shaft 68 portion. Then, after the distal end side of the push-down body 65 is positioned above the plate-like body 17, when the push-down body 65 is rotated by a fluid cylinder or the like, the front end portion of the push-down body 65 is pushed down, and the plate-like body 17 is moved up and down. Drops can be deposited on the table 18. In this case, the distal end side of the push-down body 65 that pushes down the plate-like body 17 draws an arc-like locus, but the distance to push down the plate-like body 17 is the same as that of the plate-like body 17 deposited on the lifting platform 18. It is limited to the upper surface, and the arc-shaped trajectory is a trajectory that is substantially close to a linear region.
[0034]
In addition, a restricting means 71 may be installed in front of the lifting platform 18 of the plate-like body 17 so as to be able to move forward and backward with respect to the lifting platform 18 while being spaced forward in the conveying direction of the lifting platform 18. . For example, as shown in FIG. 14, a plate-like regulating body 74 is attached to the tip of the piston rod 73 of the fluid cylinder 72, and the accumulated plate-like body 17 and / or the deposit by the fluid supply / discharge to the fluid cylinder 72. In the middle of the plate-like body 17, the regulating body 74 is pressed against the front end portion thereof, and the plate-like bodies 17 can be aligned and stacked.
[0035]
As shown in FIG. 3, when the belt-rotating prime mover 13 is driven while the telescopic conveyor 16 is held at the extended position, the plate-like body 17 is conveyed on the telescopic conveyor and reaches above the accumulation position. Then, when the motor 13 for rotating the belt is stopped to stop the rotation of the belt 12 of the telescopic conveyor 16, and then the motor 15 for moving the movable frame forward / backward is activated, the belt is positioned at the forward limit which is a component of the telescopic conveyor 16. The movable frame 9 to be moved back on the moving member 6 via the linear block 7. At this time, the front and rear movable pulleys 10 and 11 supported by the pair of front and rear of the movable frame 9 are rapidly retracted while maintaining the distance L and while maintaining the tension state of the belt 12 and above the lifting platform 18. The telescopic conveyor 16 reaches the retracted position.
[0036]
On the other hand, the fluid cylinder 56 for clamping the plate-like body 17 is operated at the position where the front end portion of the plate-like body 17 protrudes with the movement of the telescopic conveyor 16 to the retracted position, and is on the stretchable conveyor 16. The substantially central portion of the front end portion of the plate-like body 17 is sandwiched and restrained by a pair of sandwiching pieces 52 and 53 from above and below, and the plate-like body 17 holds the restrained position by the sandwiching pieces 52 and 53. In synchronization with this, the push-down body 65 that appears and disappears by the fluid cylinder 66 is projected above the front end portion of the plate-like body 17. Thereafter, when the telescopic conveyor 16 reaches the retracted position, since the two push-down means 61 are disposed in the embodiment of FIG. 1, the fluid cylinder 63 for the vertical movement of the push-down means 61 is lowered and the plate 17 The plate-like body 17 is deposited on the lifting platform 18 by pushing down the two portions of the front end portion. In addition, by operating the fluid cylinder 72 of the restricting means 71 for the plate-like body 17 deposited on the lifting platform 18, the plate-like body 17 is being deposited on the lifting platform 18 or on the lifting platform 18. Then, the regulating body 74 advances toward the lifting platform 18 and aligns the front end portions of the plate-like bodies 17 deposited on the lifting platform 18.
[0037]
After that, when the fluid cylinder 72 of the restricting means 71 is reversely operated to return the restricting body 74 to the old position, and when the fluid cylinder 56 of the restricting means 51 is reversely operated, the pair of sandwiching pieces 52 and 53 are rotated. The front end portion of the rod-like body 17 is opened, and the push-down means 65 is returned to the current position by reversely operating the vertical movement fluid cylinder 63 and the intrusion fluid cylinder 66 of the push-down means 61. The restricting means 71, the restricting means 51, and the push-down means 61 are retracted from the plate-like body 17 deposited on the lifting platform 18 and / or the front end portion of the deposited plate-like body 17.
Further, the rear part of the telescopic conveyor 16 that has reached the retracted position is connected to the relay conveyor 25 to which the next plate 17 is conveyed, and the next plate 17 conveyed from the relay conveyor 25 is conveyed. Therefore, when the prime mover 15 for moving the frame forward and backward is activated, the front and rear movable pulleys 10 and 11 of the movable frame 9 maintain the tension state of the belt 12 and maintain the interval L while maintaining the plate-like body 17. The front part of the movable frame 9 is advanced above the lifting platform 18 by rotating in the direction opposite to that during the conveyance. Then, the next plate-like body 17 transported on the relay conveyor 25 is placed on an extendable telescopic conveyor 16 that is rotated by a motor 13 for rotating the belt, and is transported above the elevator platform 18.
[0038]
Thereafter, by repeating the above operation, the plate-like body 17 conveyed from the preceding stage by the relay conveyor 25 is conveyed at a high speed on the telescopic conveyor 16 and is sequentially deposited on the elevator platform 18 from above the elevator platform 18. At this time, the detector operates in accordance with the amount of the plate-like body 17 deposited on the elevator 18 and the elevator 18 descends while maintaining an arbitrary distance from the telescopic conveyor 16 at the forward limit position. It will be.
[0039]
Note that the distance L that moves when the movable frame 9 moves forwards and backwards is set based on the length of the plate-like body 17 deposited on the lifting platform 18 in the transport direction. In the embodiment shown in FIGS. The length is comparable to the distance between the rear movable pulleys 10 and 11 before and after the cantilevered movable frame 9 is supported in a horizontal plane, but the movable frame 9 is a linear block at the rear as in this embodiment. The linear block 7 may be attached to the front and rear of the movable frame 9 so as to be movable on the moving member 6. In this case, the moving member 6 needs to be laid to the accumulation position which is the forward limit position of the movable frame 9, and the length perpendicular to the conveying direction of the plate-like body 17 is limited to the interval between the opposing moving members 6. Will be.
Also, as shown in FIG. 4, the front and rear fixed pulleys 40 and the rear movable pulley 50 are installed in a plurality of pairs while being folded back in multiple stages at arbitrary intervals in the vertical direction, so that the front and rear fixed parts attached to the machine frame 1 are fixed. The distance between the pulleys 40 and 50 can be reduced, and the installation area can be reduced. As shown in the embodiment of FIG. 4, if two pairs of the front fixed pulley 40, the rear fixed pulley 50, the front movable pulley 100, and the rear movable pulley 111 are used, the movement distance L of the front movable pulley 100 is determined. The movement interval of the rear movable pulley 111 in the horizontal plane is L / 2.
[0040]
Further, the one shown in FIG. 5 replaces the moving interval L of the movable frame 9 that moves forward and backward in the horizontal direction in the vertical direction. This is the portion of the movable frame 9 that moves forward and backward in the horizontal direction and is movable in this horizontal direction. It consists of a vertically movable frame 90 portion that replaces the distance L in which the frame 9 moves forward and backward in the vertical direction. That is, a moving member 60 such as a slide rail or a linear way is laid in the vertical direction of the machine frame 1, and a linear block 77 that moves on the moving member 60 is arranged at an arbitrary interval in the vertical direction. A vertical movable frame 90 is attached, and the linear block 77 and the vertical movable frame 90 are attached so as to be positioned below the front and rear fixed pulleys 40 and 50. A front movable pulley 100 is installed at the front of the movable frame 9, and a rear movable pulley 111 is installed at the lower part of the vertical movable frame 90. The vertical movable frame 90 is positioned at the upper limit position in the horizontal forward limit position of the movable frame 9. In addition, if the vertical movable frame 90 is controlled so as to reach the lower limit position at the horizontal retreat limit position of the movable frame 9, the installation area of the telescopic conveyor 16 and the machine frame 1 can be greatly reduced. .
[0041]
Furthermore, what is shown in FIG. 6 is that a plurality of pairs of rear movable pulleys 111 that move back and forth in the up-down direction are installed at an arbitrary interval in the front-rear direction while being folded back in multiple stages. The movement distance in the vertical direction of the rear movable pulley 111 installed on the vertical movable frame 90 can be made smaller than the movement distance L of the front movable pulley 100 of the movable frame 9 in the direction, and the installation area in the vertical direction can be reduced. Reduction is also possible. If two pairs of the front fixed pulley 40, the rear fixed pulley 50, the front movable pulley 100, and the rear movable pulley 111 are used as in the embodiment of FIG. 6, the movement distance L in the horizontal direction of the front movable pulley 100 is reduced. On the other hand, the vertical movement distance of the rear movable pulley 111 is L / 2.
[0042]
By the way, in the case where the plate-like body 17 is a veneer single plate, it is a random single plate that does not have a predetermined length with respect to the transport direction even though it has a length in the direction that intersects the transport direction in particular. There are times when the plate 17 must be deposited. This irregular veneer is used as a so-called repair veneer, and the length in the transport direction is not constant, but is indefinite and uneven. When depositing such plate-like body 17 at the deposition position, When the front end of the plate-like body 17 is aligned and deposited by the restraining means 51 or the like, the front end portion is stacked higher on the lifting platform 18, but the rear portion of the plate-like body 17 that is easily bent cannot be stacked higher than the front end. , It is easy to collapse backward at a low height. The present invention makes it possible to stably deposit such irregular single plates. As shown in FIG. 2, the elevator 18 is stopped on the downstream side corresponding to the tip portion of the plate-like body 17. A downstream stop position 19 whose position is regulated is provided, and an upstream stop position 20 which is regulated at a stop position on the upstream side where the rear end portion of the plate-like body 17 is located, and the plate-like body 17 has both stop positions 19 and 20. It will be deposited anywhere in between.
[0043]
The position control system for depositing the plate-like body 17 as described above is installed in the telescopic conveyor 16, a detector 21 for detecting the passage of the plate-like body 17 above the telescopic conveyor 16 in the retracted position, and this A selection command unit 23 is provided which includes a motor 13 for rotating the belt and a controller 22 for controlling the motor 15 for moving the frame forward and backward according to the output of the detector 21 and further commands how the plate-like body 17 is deposited. The controller 22 is connected. The detector 21 is installed on the retractable conveyor 16 or the like in the retracted position, which is a position separated from the deposition position, and detects the limit switch in contact with the conveyed plate-like body 17 or a non-contact transmission type, Any of a reflection type phototube or the like can be used, and it is detected that the front end or the rear end of the plate-like body 17 conveyed on the telescopic conveyor 16 has passed. The selection commander 23 instructs the controller 22 to stop the transported plate-like body 17, and the controller 22 sets the transported plate-like body 17 between the downstream stop position 19 and the upstream stop position 20. While being stopped at one of the two stop positions, the conveyance is stopped, and the plate-like body 17 is deposited on the lifting platform 18 with the front end or the rear end aligned.
[0044]
The controller 22 is connected to a delay circuit 24 such as a timer that decelerates the driving speed of the telescopic conveyor 16 for a set time, and the position where the plate-like body 17 conveyed from the selection commander 23 is to be deposited is downstream. When the stop position 19 is instructed, the telescopic conveyor 16 advances by a predetermined distance based on the front end detection signal of the plate-like body 17 output from the detector 21 and the action of the delay circuit 24. After the driving speed is reduced by the time set by the delay circuit 24, the front end of the plate-like body 17 is positioned above the downstream stop position 19 and the telescopic conveyor 16 is stopped. Further, when the upstream stop position 20 is instructed by the selection commander 23 as the position to be deposited, the rear end detection signal output from the detector 21 and the delay circuit 24 function. Based on this, after the telescopic conveyor 16 moves forward by a predetermined distance, the drive speed is reduced by the time set by the delay circuit 24, and then the rear end of the plate-like body 17 is positioned above the upstream stop position 20 to expand and contract the conveyor. 16 is stopped.
[0045]
For example, if the plate-like body 17 is alternately distributed and accumulated at the downstream stop position 19 and the upstream stop position 20 by the selection commanding device 23, when the front end of the plate-like body 17 is detected by the detector 21, the detection signal Based on the above, the front end of the plate-like body 17 is deposited at the downstream stop position 19. On the other hand, the detector 21 continuously outputs the rear end detection signal of the plate-like body 17 and the front end detection signal of the next plate-like body 17 to the controller 22. Is not adopted in response to a command from the selection commander 23, and thereafter, the plate-like body 17 is deposited on the upstream stop position 20 by a rear end detection signal output when the rear end of the next plate-like body 17 is detected. become. Moreover, the detector 21 of another Example can be installed not only in one piece but in a plurality, for example, two pieces at a certain interval in the direction crossing the transport direction. This is because if the plate-like body 17 is a veneer single plate, defects inherent in the plate-like body 17 itself, such as joint holes, creases and cracks, cannot be eliminated, and the plate-like body 17 can be obtained with only one detector 21. The presence of the true front end of the detector is inconvenient, and a plurality of detectors 21 are mainly installed to prevent erroneous detection.
[0046]
As another embodiment, the detector is provided with a dedicated detector for the case where the plate-like body 17 is deposited at the downstream stop position 19 and the case where the plate-like body 17 is deposited at the upstream stop position 20. The front end and the rear end of the body can be detected. That is, as shown in FIG. 10, a front end detector 41 for depositing the plate body 17 on the downstream stop position 19 based on the detection signal of the front end portion of the plate body 17 is installed above the lifting platform 18. In addition, based on the detection signal of the rear end portion of the plate-like body 17, the rear end detector 42 for depositing the plate-like body 17 at the upstream stop position 20 is deposited, and the plate-like body 17 to be conveyed is deposited. It is installed above the telescopic conveyor 16 and the like in front of the lifting platform 18. The detectors 41 and 42 are installed at positions separated by a predetermined distance L until the plate 17 can stop at the downstream stop position 19 and the upstream stop position 20 by controlling the driving speed of the telescopic conveyor 16 to be decelerated. . If the respective detectors 41 and 42 are installed at this position, the transport speed of the plate-like body 17 transported by the delay circuit 24 is slowed down so that the downstream stop position 19 and the upstream stop position 20 are accurately set. The plate-like body 17 can be stopped, and the controller 22 can deposit the plate-like body 17 at the downstream stop position 19 or the upstream stop position 20 commanded by the selection commander 23.
[0047]
The operation of the delay circuit 24 described above can be replaced with the transport control of another embodiment as shown in FIG. In other words, a belt rotating prime mover 13 for driving the telescopic conveyor 16 and a controller 22 for controlling the movable frame advancing / retracting prime mover 15 for expanding and contracting the telescopic conveyor 16 are provided, and the downstream stop from the position of the front end detector 41 is provided. A distance setter 44 that outputs a predetermined distance L from the position 19 and the detector 42 position for the rear end to the upstream stop position 20 to the controller 22, and a plate-like body that is installed on the telescopic conveyor 16 and conveyed. 17 includes a pulse transmitter 43 that outputs one pulse to the controller 22 when it has moved a predetermined distance. Further, the controller 22 includes a detector 41 for the front end and a detector 42 for the rear end. Detection output is input. The predetermined distance L from the position of the front end detector 41 to the downstream stop position 19 and the position of the rear end detector 42 to the upstream stop position 20 may be set to be the same for convenience of control and actual work. preferable.
This transport control is performed by the controller 22 based on the front end detection signal of the front end detector 41 or the rear end detection signal of the rear end detector 42 for detecting the transported plate-like body 17. The pulse generator 43 is instructed to instruct the moving prime mover 13 to perform deceleration control to place the telescopic conveyor 16 in a decelerating state, and that the plate 17 has moved the predetermined distance L set and input by the distance setting device 44. When the amount of pulses transmitted from is detected by counting up, the telescopic conveyor 16 is stopped. Next, the movable frame advancing / retracting prime mover 15 is activated to retract the telescopic conveyor 16, and the plate-like body 17 is dropped and accumulated at the downstream stop position 19 or the upstream stop position 20 of the lift 18.
[0048]
Further, the embodiment shown in FIG. 10 does not have a configuration in which the upper part of the machine frame 1 on which the telescopic conveyor 16 is arranged is installed in a substantially horizontal state so that the telescopic conveyor 16 moves forward and backward. The body 17 is installed with a downward gradient toward the direction of the deposition position. If the machine frame 1 on which the telescopic conveyor 16 is arranged is inclined downward in the conveying direction in this way, when the telescopic conveyor 16 is retracted, the movable frame 9 portion is moved from the deposition position of the plate-like body 17 by the lifting angle corresponding to the gradient. In addition to being able to be separated from each other, the accumulated plate-like body 17 and the front portion of the telescopic conveyor 16 can be brought close to each other at the advanced position. Accordingly, even if the plate-like body 17 immediately after deposition is swung up by negative pressure while the telescopic conveyor 16 is moving backward, or the plate-like body 17 is bent, twisted, warped, particularly upwardly warped, the plate-like body 17 is Contact between the end portion and the retractable telescopic conveyor 16 is avoided.
[0049]
FIG. 7 and FIG. 8 show an embodiment in which a plurality of the stretchable conveyors 16 are arranged in series in the transport direction, and an elevator base 18 that constitutes a deposition position of the plate-like body 17 is arranged therebetween. The sorting position is determined according to the grade, type, quality, etc. of the plate-like body 17 to be delivered, and this plate-like body 17 is sorted and deposited on the designated lifting platform 18. The stretchable conveyor 16 in the illustrated example is composed of three pieces. For convenience, a method is adopted in which the stretchable conveyor 16 extends and contracts in the horizontal direction via a vertical movable frame 90 that moves in the vertical direction of the machine frame 1 shown in FIG. Three elevators 18 that are positions where the plate-like body 17 is deposited are installed, and usually one of the plurality of deposition positions is adopted as the elevator 18 that deposits a random single plate. At the accumulation position, as described above, the downstream stop position 19 in which the front end portion of the plate-like body 17 is set as the stop position regulating side, and the rear end portion of the plate-like body 17 at the upstream side of the deposition position is regulated at the stop position. Two stop positions, the upstream stop position 20 on the side, are prepared, and are accumulated based on a command from the selection commander 23. In addition, when there is a clearance between the forward limit position of the movable frame 9 of the telescopic conveyor 16 positioned at the rear stage and the rear fixed pulley 5 of the telescopic conveyor 16 positioned in front of the movable frame 9, a relay conveyor 25 that performs delivery within this clearance is provided. The movable frame 9 of the telescopic conveyor 16 that is installed or rearward is transported on the telescopic conveyor 16 as a position where the advance limit position of the movable frame 9 is slightly complicated in the rear fixed pulley 5 of the telescopic conveyor 16 positioned in front of it. It is assumed that the plate-like body 17 is transferred to the front telescopic conveyor 16.
[0050]
In the illustrated example, there is a clearance between the operating position of the movable frame 9 of the telescopic conveyor 16 positioned at the rear and the rear fixed pulley 5 of the telescopic conveyor 16 positioned at the front thereof. This clearance is as described above. A relay conveyor 25 is interposed. The relay conveyor 25 has the same conveying surface as the stretchable conveyor 16 located at the rear, and the plate-like body 17 can be smoothly transferred to the relay conveyor 25 from the stretchable conveyor 16 located at the subsequent stage. In addition, the rear portion is positioned at least in front of the position where the telescopic conveyor 16 located behind the plate-like body 17 is deposited, and the plate-like body 17 is not obstructed by the relay conveyor 25 and is placed on the lifting platform 18. It can be deposited. Further, the front position of the relay conveyor 25 is set to a position that does not interfere at least when the movable frame 9 of the telescopic conveyor 16 positioned in front is operated. In the illustrated example, the transport surface of the telescopic conveyor 16 located in front is set slightly lower than the transport surface of the relay conveyor 25. For this reason, the plate-like body 17 can shorten the conveyance distance ahead without being influenced by the operating state of the telescopic conveyor 16 located in front. In the case where three telescopic conveyors 16 are installed in series in the transport direction as in the embodiment, the transport surface of the plate-like body 17 is set to be low over three stages.
[0051]
In the illustrated example, a carry-in conveyor 27 is installed at the rear end position of the telescopic conveyor 16 located at the rearmost portion in the same manner as the relay conveyor 25. The carry-in conveyor 27 is driven via a continuously variable transmission 26. The speed of the carry-in conveyor 27 is changed by the continuously variable transmission 26, and the plate-like body 17 conveyed from the previous stage is finally finished at an appropriate timing. It can be put on the telescopic conveyor 16 located in the section. The carry-in conveyor 27 is provided with a sorting position 28 of the plate-like body 17 to be conveyed. At this sorting position 28, the sorting of the plate-like body 17 conveyed from the preceding step is artificially determined or the plate-like body 17 is separated. A detector for detecting the grade, properties, and defects of the body 17 is installed, and in the embodiment, a sorting signal 29 for sorting and depositing the plate-like body 17 on any of the three elevators 18 is transmitted. In order to eliminate the clearance between the carry-in conveyor 27 and the start end position of the telescopic conveyor 16 located at the rearmost part, the front end of the carry-in conveyor 27 is slightly inserted into the rear fixed pulley 5 of the telescopic conveyor 16. Alternatively, the relay conveyor 25 can be interposed between the carry-in conveyor 27 and the starting end position of the telescopic conveyor 16. Further, instead of the carry-in conveyor, the relay conveyor 25 itself may function as the carry-in conveyor 27.
[0052]
At the sorting position of the carry-in conveyor,
As a control system for sorting and depositing the plate-like bodies 17 that have been sorted and sorted on each lifting platform 18, the plate-like bodies 17 up to each lifting platform 18 set to sort and deposit from the sorting position 28 on the carry-in conveyor 27 are used. When the movement distance is set as a predetermined distance and the operation system of the telescopic conveyor 16 is controlled at the time when the predetermined distance is measured, or when the discriminated plate-like body 17 reaches the lifting platform 18 to be sorted Therefore, the operating system of the telescopic conveyor 16 is controlled.
[0053]
Specifically, according to the former control system shown in FIG. 7, the sorting signal 29 at the sorting position 28 on the carry-in conveyor 27 is linked to the distance setting device 31, and the plate-like body 17 conveyed from the sorting position 28. The distances S1, S2, and S3 to the deposition position are converted into a pulse amount in which a predetermined moving distance of the plate-like body 17 in the telescopic conveyor 16 is one pulse, and the memory corresponding to each plate-like body 17 to be conveyed is stored. The data is output to a storage device 32 having an element and stored in the storage element. The continuously variable transmission 26 of the carry-in conveyor 27 is linked to a pulse transmitter 30 that emits a pulse amount in which the predetermined moving distance of the plate-like body 17 associated with the drive rotation of the carry-in conveyor 27 is one pulse. The pulse transmitter 30 is connected to the distance setting device 31, and the moving pulse amount of the plate-like body 17 on the carry-in conveyor 27 is output to the storage device 32 via the distance setting device 31. The storage device 32 is connected in series to the belt-rotating prime mover 13 and the movable-frame advance / retreat prime mover 15 which are operating systems of the telescopic conveyor 16, and controls them.
[0054]
According to this control circuit, the sorting signal 29 of the plate-like body 17 at the sorting position 28 on the carry-in conveyor 27 is converted into a pulse amount and stored in the storage device 32 from the distance setting device 31 and is conveyed. The total of the movement pulse amount on the carry-in conveyor 27 which is a variable speed of the body 17 and the movement pulse amount on the telescopic conveyor 16 sent at a constant speed is the distance to the deposition position stored in the storage element 28. When each storage element in the device 32 counts up, the storage device 32 stops the prime mover 13 for rotating the belt of the telescopic conveyor 16, resets the storage device, and activates the prime mover 15 for moving the frame forward and backward. Then, the movable frame 9 located at the forward limit is moved backward, and the plate-like body 17 is deposited on the lifting platform 18 at the set deposition position, which is the sorting position of the carry-in conveyor 16.On the stretchable conveyor 16 on which the plate-like bodies 17 are sorted and deposited, control is performed to reduce the inertia of the plate-like body 17 at the stop position by reducing the rotational speed of the belt 12 of the stretchable conveyor 16 just before stopping. When the correction setter 33 is connected to the distance setter 31 in the circuit and the accumulated pulse amount approaches the count up, the correction setter 33 sends a deceleration command to the motor 13 for rotating the belt of the telescopic conveyor 16. May be transmitted in a plurality of stages to control the speed corresponding to the position of the plate-like body 17 in the course of conveyance.
[0055]
As the latter control system, as shown in FIG. 8, each time the plate-like body 17 that has been classified at the sorting position 28 of the carry-in conveyor 27 passes, a counter 34 that detects the carrying order is provided. The sorting signal 29 for specifying the deposition position of the plate-like body 17 transmitted from the sorting position 28 of the carry-in conveyor 27 is stored in synchronization with the detection signal 35 of the plate-like body 17 from the counter 34. Output to each storage element in the device 32. On the other hand, a detector 36 such as a photoelectric tube or a limit switch for detecting the front end of the plate-like body 17 conveyed on the stretchable conveyer 16 is provided above the elevator 18 installed at each deposition position of the plate-like body 17. The output of the detector 36 is connected to the storage device 32, and the detection output by the detector 36 of the plate-like body 17 conveyed on the telescopic conveyor 16 is output to the storage device 32. The storage device 32 is based on the stored sorting data, the storage data by the counter 34 for specifying the plate-like member 17 to be conveyed, and the detection output of the plate-like member conveyed on the telescopic conveyor 16 from the detector 32. When the plate-like body 17 is transported to the sorting position 28 and reaches the determined lifting platform 18 to be sorted, the operating system of the telescopic conveyor 16 is controlled.
[0056]
That is, if the plate-like body 17 determined at the sorting position 28 is deposited on the third elevator 18 which is the foremost part, the detectors 36 installed in the first and second units are provided. Even if the plate-like body 17 can be detected on the telescopic conveyor 16, an output prohibition signal 37 for the operating system of the telescopic conveyor 16 is transmitted from the storage element in the storage 32 based on the stored data from the counter 34. Thus, the plate-like body 17 passes over the belt 12 of the first and second extendable conveyors 16 that continue to rotate. When the detector 36 detects the plate-like body 17 on the belt 12 of the third telescopic conveyor 16, the memory 32 stores the motor 13 for rotating the belt of the third telescopic conveyor 16, as in the former control system. Is stopped, the storage element is reset, the movable frame advance / retreat motor 15 is activated to move the movable frame 9 located at the forward limit, and the plate-like body 17 is moved to the sorting position of the carry-in conveyor 27. It is deposited on the lifting platform 18 at the set deposition position. Similarly to the former control system, on the stretchable conveyor 16 on which the plate-like bodies 17 are sorted and deposited, the rotational speed of the belt 12 of the stretchable conveyor 16 just before stopping is reduced to reduce the plate-like body 17 at the stop position. When the inertia is attenuated, a correction detector 38 is installed at a position before the detector 36, and the belt rotation of the telescopic conveyor 16 is performed by a correction circuit corresponding to the correction detector 38 provided in the storage device 32. Speed control may be performed in accordance with the position of the plate-like body 17 in the course of conveyance by transmitting a deceleration command to the driving prime mover 13 in a plurality of stages.
