DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for unloading only the uppermost sheet from a pile of veneer veneers, plywood, laminated veneer, etc., deposited on an elevator, to the next step. It concerns the device.

[0002]

2. Description of the Related Art Conventionally, when supplying only the uppermost plate from a pile of plates, it is held by suction through a vacuum suction mechanism or by sticking operation of a needle-like body. Although it was held, two or more plate bodies were often unloaded at the same time, so that workability in the next step was significantly reduced.

[0003] In the former suction holding method, the second and subsequent sheets are frequently held at the same time based on the properties inherent in the woody plate. That is, among the wood-based plates, veneer veneers, regardless of the thickness of the veneer, can be used to simultaneously hold the second and lower plates through the conduit grooves, knot holes, crevices, cracks, etc. through suction during suction. In addition, not only veneer veneer, but also veneer veneer veneer veneer laminated with fiber perpendicular to each other, veneer veneer veneer veneer veneer veneer veneer veneer veneer veneer veneer veneer Due to the adhesive leaked from the adhesive layer, the wet state of the wood, etc., it is lightly adhered to each other during the deposition and rises together, and further, this negative rise also occurs due to the negative pressure acting between the layers of each plate. Had occurred.

[0004] In the latter stab holding method, not only the uppermost plate but also the uppermost plate due to excessive or insufficient pressing force at the time of stabbing.
In some cases, the second and lower sheets may be simultaneously stabbed, or a sufficient holding force to raise the plate may not be obtained.

[0005] With respect to the above description, as disclosed in, for example, JP-A-51-95357, a head having a bottom having substantially the same size is provided on the top of a veneer veneer stack. A roller conveyor that sends veneer veneer to the next process in the head, and two telescopic pipes are arranged in the space between the roller conveyors. A suction pipe is connected to the end of each pipe via a joint, and the telescopic pipe is lowered. When the veneer veneer is sucked and lifted by the suction pipe, the veneer is bent inward or outward with the joint as a fulcrum. When two or more veneers are simultaneously sucked, the first and second veneers are bent by this bending. If a gap occurs between the close contact portions, the close contact is released, and the entire upper surface of the veneer is sucked by the roller conveyor in the head as the telescopic pipe rises, and is supplied to the next process. Is shall.

[0006] Japanese Patent Publication No. 2-37283 discloses that
Similarly, from the pile of veneer veneer placed on the elevator,
A technique for separating and supplying the top veneer veneer has been disclosed.According to this, from the pile of veneer veneers placed on the elevating platform, when separating and supplying the top veneer veneer, A suction device having a carrier is fixedly arranged above and arranged,
In addition, the separate suction mechanisms that give buoyancy to the veneer veneer at the front and rear positions can be moved up and down, and the three-part vacuum suction mechanism separates and holds the veneer veneer separately while bending the first half slightly. By restraining the driving force of the transporting body applied to the veneer veneer to a slip state, then, by lowering the regulating plate covering the bottom in the front suction mechanism, and lowering the detachment operating body in the rear suction mechanism, The driving force of the carrier is passively supplied to the veneer veneer and supplied forward.

[Problems to be solved by the invention]

However, in each of the above-mentioned conventional examples, the target plate is a veneer veneer which is relatively vulnerable. It separates layers from the second and lower sheets, and is not suitable for relatively rigid plate bodies such as plywood and veneer laminates. In addition, the adjoining of the second and lower veneer sheets during adsorption of veneer veneers. Regardless of the ascent, the bending operation is repeated, so if the second and subsequent veneer veneers are not simultaneously sucked, this bending operation step becomes an extra operation in the unloading step, and the work efficiency is inevitably reduced. I was letting it.

[0008] In particular, even among wood-based boards, the occurrence of polymerization feed varies depending on the properties of the board carried out to the next step, for example, a relatively large amount of fat,
When the raw veneer veneer in the wet state is carried out to the drying process, when the veneer veneer after drying is carried out to the mechanical process, or when several tens of sets are temporarily applied by applying an adhesive between the layers of the veneer veneer. In the piles of the bonded plate bodies, in particular, the grease, the adhesive applied between the layers of the veneer veneer, etc., are leaking out. In the present situation, when a plate body after hot pressing is carried out one sheet at a time to the next four-circle sawing process, the frequency of carrying out two or more plate bodies at the same time differs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. The pile 4 of the plate body 3 is placed on the elevator 2 located in the gate-shaped machine frame 1, and the height of the upper surface is detected by a detector (not shown) such as a photoelectric tube and a limit switch. , Is always maintained at a constant height. A drive shaft 5 and a driven shaft 6 are supported at the front of the machine frame 1 in the plate body unloading direction, and a chain wheel 7 is mounted on the drive shaft 5 and the driven shaft 6 so as to be located at the four corners of the machine frame 1. A pair of chains 8 is placed between the front and rear chain wheels 7 orthogonal to the plate body unloading direction, and a lifting body 9 is provided at the front end of each chain 8 and a lifting body 9 is provided at the rear end of each chain 8.
Is connected to a rod of a fluid cylinder or a balance weight 10 as shown in the drawing, and the elevating body 9 is suspended and supported in a normal state.

The elevating body 9 has a pair of guide rollers 11 supported at arbitrary intervals in the vertical direction. The elevating body 9 is slidable with a front support 1A constituting the machine frame 1 as a guide. The drive of a fluid cylinder installed on the upper part of the motor or a prime mover 12 as shown in the figure is transmitted to the drive shaft 5 so that the elevating body 9 can be raised and lowered.

On both sides of the lifting / lowering body 9 in the direction in which the plate is carried out,
A guide rod 13 is attached along the plate body unloading direction, and both ends of the frame 14 are fitted into the guide rod 13 to
In accordance with the size of the plate 3 deposited on the lift 2 by a motor, a crank mechanism, or a fluid cylinder 15 as shown, the frame 14 is moved in the plate discharge direction.
Is adjustable. The dimensions of the plate 3 are constant,

In the frame 14, a pair of lifting and lowering mechanisms 16 including a motor, a crank mechanism, and a fluid cylinder as shown in FIG. Either a suction member 18 is attached to a supporting member 17 linked to each lifting mechanism 16 to enable a pair of suction members 18 to be individually operable, or the suction member 18 is provided at a substantially central portion in a direction orthogonal to the plate body unloading direction. A single lifting mechanism 16 is mounted, and a pair of suction tools 18 are installed on a support member 17 linked to the lifting mechanism 16 at an arbitrary interval in a direction orthogonal to the plate body unloading direction. Is connected to a vacuum generator (not shown) via a suction duct (not shown). The suction device 18 is pivotally supported so as to be capable of tilting so as to enable the supporting state of the plate body 3 to be suction-held and the equilibrium support to the tilt support. The support member 17 has a weighing scale for measuring the weight of the plate 3, and in the illustrated example, one load cell 19 of a strain gauge type is provided for each suction tool 18, and the plate 3 held by suction is held. This is captured as a signal of a physical quantity proportional to the load.

A reciprocating mechanism 20 comprising a motor, a crank mechanism, and a fluid cylinder as shown in FIG. Are mounted in pairs, and each reciprocating mechanism 20
A guide mechanism including a pair of guide shafts 21 is laid with the reciprocating mechanism 20 interposed therebetween in order to guide the reciprocating movable range.
The extruding piece 2 that engages the rear portion of the plate 3 with the reciprocating mechanism 20
2 is attached. The surface of the extruded piece 22 that engages with the rear portion of the plate 3 depends on the properties of the plate 3 to be carried out. Dozens of sets are temporarily adhered by applying the agent, and the four peripheral edges are irregular and in a temporarily adhered state, so that they are curved in order to prevent separation between the layers, or after hot pressing from the pressing step In the case where one plate 3 is carried out one by one to the next four-circle sawing step, the four peripheral edges are in an adhesive state, so that the section 3 having the receiving portion of the plate 3 has a U-shape. Things.

Further, a motor, a crank mechanism, and a fluid cylinder 23 as shown in the drawing are attached to the support member 17, and an impact is applied to the top of the plate 3 at the tip of the piston rod 24. A detachable operating body 25 to be provided is attached, and when the load cell 19 of the strain gauge type exceeds an arbitrarily set load, a circuit is configured to operate arbitrarily a number of times or continuously for an arbitrary time.

An unloading conveyor 26 is installed upstream of the machine frame 1 in the sheet unloading direction, and a pair of upper and lower pinch rolls 27 installed downstream of the unloading conveyor 26 in the unloading direction.
In the vicinity of the unloading side, contact type detectors such as limit switches and cam floors can be adjusted in the vertical direction according to the thickness of the plate 3 so that the thickness of one unloaded plate 3 is slightly reduced. When the detector is installed with a margin, and the upper surface of the plate 3 to be carried out is detected by this detector, it is determined that the stacking feed is performed,
Alternatively, a phototube, an ultrasonic wave, a laser displacement type non-contact type detector 28 as shown in the illustrated example is installed at a position above the transport surface,
By subtracting a value obtained by adding a margin to the thickness of one plate 3 from the position of the detector 28 and the distance to the transport surface, the upper surface of the plate 3 to be carried out is detected by the detector 28. If the detected distance is equal to or longer than the set distance, it is determined that the overlap feed is performed, and the driving of the pinch roll 27 is controlled.

Next, the operation will be described. First, the upper surface of the pile of the plate 3 is set to a constant height by the operation of the elevator 2, and the fluid cylinder is operated according to the dimensions of the plate 3 to adjust the position of the frame 14 with respect to the plate discharge direction. The vertical position is adjusted in the case of a contact type detector according to the thickness of the plate 3 to be carried out, and the set distance is adjusted in the case of a non-contact type detector 28 as shown. At this time, it is assumed that the load per sheet 3 to be carried out is set to the load cell 19 of the strain gauge type according to the illustrated example. Specifically, the load of the plate 3 is calculated by a calculation formula based on each element such as the length, width, thickness, specific gravity, etc. of the plate 3, or the plate 3 is actually replaced by one sheet as described later. By holding by suction, a signal of a physical quantity proportional to the load applied at this time is set.

In this state, as described above,
For example, in unloading the plate 3 to a pressing step in which the simultaneous feeding of two sheets frequently occurs, the support member 17 is lowered by operating the elevating mechanism 16 attached to the frame 14, and the support member 17 is removed. The attached suction tool 18 reaches the rear upper surface of the pile, and sucks the rear portion of the uppermost plate 3 at two points perpendicular to the unloading direction. After the suction, the lifting mechanism 1 is held while holding the plate 3 by suction.
6, the supporting member 17 is moved up, and the pair of suction tools 18 are temporarily stopped at the upper limit. The suction tool 18 is in a state of being inclined downward in the plate body unloading direction, and the plate body 3 held by suction is lifted at the rear,
The front part is in a so-called cantilever state, in which it is grounded on a pile.

The plate body 3 which is once sucked and held at the upper limit is captured by the strain gauge type load cell 19 as a signal of a physical quantity proportional to the load each time, and a predetermined plate per sheet is set. The load of the body 3 will be compared. As a result of this comparison, if the load is substantially the same as the initially set load, it is determined that the plate body 3 held by suction is a single sheet, and a pair of extruded pieces waiting on the downstream side in the plate body unloading direction. The suction tool 18 is moved by the operation of the reciprocating mechanism 20.
At this time, the suction operation from the suction tool 18 is temporarily stopped to release the suction of the plate 3, and then the reciprocating mechanism is further engaged. 20 is moved forward and carried out between the pair of pinch rolls 27 while the front portion of the plate 3 is guided by the delivery guide. If the suction of the plate 3 is not released only by stopping the suction action from the suction tool 18, the suction action from the suction tool 18 is temporarily stopped, and conversely, compressed air is injected from the suction tool 18. Accordingly, the suction between the suction tool 18 and the plate 3 may be forcibly released.

If the load of the plate 3 held by suction is different from the initially set load, it is determined that the number of sheets is two or more. An impact is applied to the upper surface of the body 3 by the detachment operating body 25, and this operation is continuously performed an arbitrary number of times or for an arbitrary time until the value of the strain gauge type load cell 19 reaches the set load. The plate 3 is dropped. If the value of the strain gauge type load cell 19 does not change during this work process, the work is temporarily stopped and the second and subsequent plates 3 are artificially removed.

Next, as described above, a pair of extruded pieces 2
2 is engaged with the rear portion of the plate 3, and the reciprocating mechanism 20
Is carried forward and is carried out between the pair of pinch rolls 27 while the front portion of the plate 3 is guided by the delivery guide. At this time, the plate 3 to be carried out has an extruded piece 2 at the rear.
2, the front part is in a cantilever shape with the ground contacting on the pile, but the front part of the uppermost plate 3 and the second plate 3 on the pile are still interlayer-separated. Not particularly fat,
When the adhesive or the like applied between the layers of the veneer veneer is leaking, it is in a temporarily bonded state, and the two plate members 3 are simultaneously carried out to a pair of upper and lower pinch rolls 27. When two plates 3 pass the pinch roll 27 at the same time, the detector 28 detects the upper surface of the plate 3 to be carried out, and determines that it is a stacking feed. Or simultaneously stop the driving of the pinch roll 27 to prevent the simultaneous transport of the two plates 3 onto the carry-out conveyor 26, and also temporarily stop the next plate suction step, and The second plate 3 is removed.

Further, when the plate 3 is carried out to the above-described four-turn sawing step where the frequency of simultaneous suction of two sheets is relatively low, for example, the plate 3 held by the strain gauge type load cell 19 is held one by one. Without measuring the load, the pair of suction mechanisms on the frame 14 are moved and adjusted to both ends orthogonal to the plate unloading direction, and then each suction tool 18 is moved to the upper surface of the plate 3 at the top of the pile. Lower it. Next, when the suction of one of the suction devices 18 is first started, the layer between the uppermost plate 3 on the suction side and the second sheet is placed on the other suction device 18 side where suction has not yet started. Is lifted up slightly with the fulcrum as a fulcrum, and the other suction device 18 is suctioned with a time lag, and the suction device 18 is raised to the upper limit while the plate body 3 is suction-held. At this time, if the thickness of the plate 3 is relatively small, the detaching operation body 25 is lowered to release the suction of the suction tool 18 while giving an impact to the plate 3, and
If the thickness is relatively large, the suction of the suction device 18 is released without operating the detachment operation body 25, and compressed air is injected from the released suction device 18 onto the surface of the plate 3, and the rear portion of the plate 3 is released. The plate 22 is moved forward in the sheet discharging direction with the extruded piece 22 interposed therebetween.

Thereafter, the unloading operation of the plate 3 is repeated, but when the plate 3 to be unloaded is lost on the elevator 2 and a pile of the plate 3 for one lot is newly loaded, or At the time of maintenance and inspection, the prime mover is operated to raise the elevating body 9 along the machine frame 1 to open the vertical space in the machine frame 1. After carrying in the plate body 3 or checking, the elevating body 9 is moved. It is to return to the original position.

[0032]

As described above, according to the present invention, the adsorbent is lowered from the frame by an arbitrary distance, and the uppermost plate of the pile of the plates placed on the elevating table is moved to either one of the piles. Suction is performed with a time lag from the suction device in order, the suction device is lifted up while holding the plate body to reach the upper limit, the suction of the suction device is released, and compressed air is ejected from the suction device, and then the plate body is Since the extruded piece is interposed in the rear part and reciprocated in the direction of carrying out the plate body, firstly, interlayer separation from the second sheet can be achieved at the time of suction of the uppermost plate body, and compressed air immediately after the suction is released by the suction tool itself. To separate and drop the second and lower plates. In addition to the above operation, by lowering the detachable operating body when the plate body is sucked and held to give an impact to the plate body, it is particularly effective for separating and dropping the second or lower plate body in a thin plate body. is there.

Further, the suction device is lowered from the frame by an arbitrary distance to suction the uppermost plate of the pile of piles of the plates placed on the elevating table, and the suction device is raised while holding the plate by suction. When the weight reaches the upper limit and the weight of the plate body held by suction exceeds the weight per sheet, the release operating body is lowered to release the suction of the suction tool while giving an impact to the plate body, and then Since the extruded piece is interposed in the rear part of the plate and moved forward in the plate unloading direction, it is possible to accurately cope with the simultaneous holding of two sheets, and in addition to this, the compressed air is jetted to the suction tool itself immediately after the suction is released. Thus, the second and subsequent plates can be separated and dropped.
