Description

  In the present invention, a finger joint process is applied to both ends, and a wood element row formed by connecting a plurality of wood elements coated with an adhesive to the finger joints by temporary press-fitting of the finger joints is added from the length direction. The present invention relates to a finger joint rotary pressing device that obtains a wood joined body by pressing and pressing the finger joint.

  In order to obtain a long wood, as shown in FIGS. 14A and 14B, finger joints b are processed at both ends of the wood element a in the longitudinal direction, and a plurality of wood elements a are joined by the finger joints b. Thus, there is a method of obtaining a wood joined body, and a finger joint pressing device is used for joining the wood elements a.

  Conventionally, as shown in FIGS. 12 and 13, a pressing device (finger composer) 1 for pressing wood element rows is used in combination with a feeding mechanism 2 and a temporary press-fitting device 3 arranged in the preceding stage. A wood element a having an adhesive applied to a finger joint b processed into a mouth end is supported by a feeding mechanism 2 and sent to a temporary press-fitting device 3, and the temporary press-fitting device 3 is fed to the finger joint b of the wood element a being fed. Is press-fitted into a wood element row A, which is fed into the pressing device 1 located in the front, and the wood element row A cut into a predetermined length by the pressing device 1 is subjected to the main pressing. .

  In order to connect the wood elements a, in FIGS. 12A and 12B, the wood elements a are sequentially fed forward in series by the feed mechanism 2, and the feed speed of the feed mechanism 2 is changed to the feed speed of the temporary press-fitting device 3. The finger joint b, to which the adhesive of the front and rear wood elements a is applied, is continuously temporarily press-fitted while the wood element a is being fed by the temporary press-fitting device 3 due to the speed difference. When the wood element row A is fed onto the receiving line L of the pressing device 1 and the leading end of the wood element row A is detected by the set length determining sensor 4, the feeding mechanism 2 and the temporary press-fitting device 3 are stopped. Then, the wood element row A is cut into a fixed length by a fixed cutting saw 5 provided on the entry side of the receiving line L of the pressing device 1.

The wood element row A on the receiving line cut to a predetermined length in this way is a transverse feed pusher using a cylinder from one lateral direction perpendicular to the feed direction of the wood element row A as shown in FIG. 6 is traversing on pressing the line L _1, in on the clamping line L _1, is brought into contact with the head portion of the cylinder 7 to the cut end of the timber element column a by the action of the clamping cylinder 7, wood element sequence When A is pressed in the row direction, the leading end of the preceding wood element abuts against the stopper 8 and the movement in the row direction stops.

  As a result, the wood element row A is sandwiched between the stopper 8 and the head portion of the compression cylinder 7 and is subjected to main compression, so that the finger joint b that has been press-fitted into the wood element row A is opposed to the opposing surface by an adhesive. Are bonded and integrated into a long wood joined body having a predetermined length.

  The buckling in the upper direction and the lateral direction of the wood element row A at the time of pressing is prevented by applying pressure by the upper surface presser 9 and the side surface pressers 10 and 10-1.

The conventional finger joint pressing device 1 as described above cuts the wood element row A in a temporarily press-fitted state into a set length, and then feeds the wood element row A to the wood element row A. from one lateral direction perpendicular to the direction, but is adapted to the transverse feed on pressing the line L ₁ in the transverse feed pusher 6 with cylinders, movement of the lateral feeding pusher 6 is reciprocally by an air cylinder for exercise, because, in a state in which the piston rod protrudes on the line receive when traversing pusher 6 is moved forward to traversing the timber element column a on clamping line L _1, the following The wood element row A cannot be fed onto the receiving line L. For this reason, in the feeding of the wood element row A, a long time is required until the lateral feed pusher 6 moves backward and the shutter descends. Latency occurs, the waiting time is disadvantageously inhibits raise the productivity of the timber assembly.

  Accordingly, an object of the present invention is to solve the above-described problems, in the case where the wood element row is laterally fed from the receiving line to the pressing line, the subsequent wood element row is received on the receiving line simultaneously with the completion of the lateral feed. It is an object of the present invention to provide a finger joint pressing device that can improve the productivity of a wood joined body by shortening the waiting time for feeding wood element rows.

  In order to solve the above-mentioned problem, the present invention provides a wood element row formed by connecting a plurality of wood elements having finger joints processed at both ends of the length direction by temporary press-fitting of the finger joints, and the length direction A receiving line that supports the wood element row fed along the cutting line and cuts it to a predetermined length, and is provided at one side of the receiving line and supports the wood element row fed from the receiving line. A pressing line that presses the wood element row from the length direction, and the receiving line and the pressing line are arranged at a plurality of positions in the length direction of the wood element row, and the wood element row on the receiving line is pressed to the pressing line. It is composed of a lateral feed mechanism that moves up, and the lateral feed mechanism uses an endless chain in which the upper straight running part is arranged perpendicular to the receiving line and the pressing line. By giving the endless chain an intermittent rotation with a driving means by a driving means, a pusher attached to this chain at a fixed interval so that the wood element row on the receiving line is laterally fed onto the pressing line. The formed structure is adopted.

  A pusher rodless cylinder in which the driving means of the lateral feed mechanism is arranged in parallel with the lower position of the upper running portion of the endless chain and reciprocates a pusher pawl that can be raised and lowered by a fixed stroke in the rotation direction of the chain. The pusher claw is engaged with the receiving claw attached to the endless chain at regular intervals during its forward movement, so that the chain is fed by a fixed stroke, and when it moves backward, it passes over the next position receiving claw. Thus, the structure can be made so as to return to the position where it can be engaged with the next position receiving claw.

  Further, the rodless cylinder used for the driving means of the lateral feed mechanism may be adjustable in the reciprocating direction of the pusher claw.

  Furthermore, the driving means of the lateral feed mechanism may be a servo motor, and one of the sprockets positioned at both ends of the upper running portion of the endless chain is driven by the servo motor, so that the chain is fed at a constant stroke. it can.

  Here, in the endless chain forming the lateral feed mechanism, when the upper surface of the upper straight running portion is at the same level as the receiving line and the pressing line, and the driving means is given a certain stroke, the upper surface of the straight running portion is The pusher located at the position engages with the wood element row on the receiving line, and this wood element row is to be laterally fed onto the pressing line.

  The upper surface of the upper straight running part of the above endless chain is at the same level as the receiving line and the pressing line, and the wood element row is laterally fed by the pusher attached to this chain, so the wood element row is laterally fed onto the pressing line. In this state, there are no protrusions on the receiving line, so that the next wood element row can be fed onto the receiving line without any trouble as soon as the lateral feed is completed, and the waiting time for feeding the next wood element row is shortened. be able to.

  According to the present invention, the endless chain in which the upper straight running portion is disposed perpendicular to the receiving line and the pressing line is used as the lateral feed mechanism for transferring the wood element row on the receiving line to the pressing line. Because the pusher attached to the chain at a fixed interval by giving the chain to the chain for a certain stroke by driving means, the row of wood elements on the receiving line is formed to be laterally fed onto the pressing line. In the state where the wood element row is laterally fed on the pressing line, there is no protrusion on the receiving line, and the next wood element row can be fed onto the receiving line at the same time as the horizontal feeding of the wood element row is completed. It is possible to reduce the waiting time for feeding the next wood element row and improve the productivity of the long wood joined body.

As shown in FIG. 1, the lateral feed mechanism 18 is arranged at predetermined positions at predetermined positions in the middle of the receiving line L and the pressing line L _{1 in} the longitudinal direction, and is endless for the lateral feed of the wood element row A. using thien 45, a straight running portion of the upper portion of the endless chain 45 and arranged perpendicular to the receiving line L and clamping the line L _1, by providing the intermittent rotation of the fixed stroke driving means to the endless chain 45, this pusher 46 attached to the chain 45 in the arrangement of regular intervals, it is formed wood element sequence a on receiving the line L such that the transverse feed on pressing the line L _1.

As shown in FIGS. 2 and 3, the endless chain 45 is wound around the outer periphery of chain guides 49, 50 mounted between the sprockets 47, 48 mounted on both upper sides of the support frame 19 and on both lower sides of the support frame 19. , a straight upper running portion 45a in the horizontal between the sprockets 47 and 48, the upper running portion 45a is perpendicular to the line L and the clamping line _{L 1} receives, receives the line L and clamping the bottom plate 20 of the line _{L 1} is The upper part of the bottom plate 20 and the upper part of the upper traveling part 45a supported at the lower part by the chain receiver 51 have the same plane height and are arranged in the wood element row to the receiving line L. Can enter without any trouble.

  Pushers 46 in the form of a belt plate having a length corresponding to the substantially entire length of the support frame 19 are fixed to the outer circumference of each endless chain 45 at regular intervals in the traveling direction, and the upper traveling portion 45a is rotated when the endless chain 45 is rotated. The pusher 46 positioned at the side moves laterally on the bottom plate 20.

  A pusher receiving pawl 52 that protrudes toward the inner peripheral side of the endless chain 45 is fixed to one side of the endless chain 45 at a portion where the endless chain 45 is sandwiched on the lower surface side of each pusher 46. As shown in FIG. 7, a pusher positioning tool 53 is fixed to the other side. Therefore, the pusher 46, the receiving claw 52, and the pusher positioning tool 53 are attached to each endless chain 45 at the same constant interval in the rotation direction of the chain 45.

  A rodless cylinder 54 serving as a driving means for intermittently running the endless chains 45 in a position directly below the receiving claws 52 below the upper running sections 45a of the endless chains 45 is parallel to the upper running sections 45a. The rodless cylinder 54 is placed and fixed on a movable plate 56 provided so as to be movable on the upper surface of a fixed plate 55 attached to the support frame 19, and is positioned in the traveling direction of the upper traveling portion 45a. It can be adjusted.

  The rodless cylinder 54 is provided with a linear advancing / retracting member 57 which reciprocates a stroke equal to the arrangement interval of the pushers 46 by supplying / discharging the pressure fluid, and a pusher claw 58 is attached to the upper surface of the linear advancing / retracting member 57. ing. The pusher claw 58 is elastically supported in a direction in which the lower part is pivotally supported by the linear advancing / retracting member 57 with a pin so that the pusher claw 58 can be laid down from the standing state to the front side in the traveling direction of the upper traveling part 45a. Is energized.

As shown by the solid line in FIG. 3, the pusher pawl 58 of the rodless cylinder 54 stands at the rear of the receiving pawl 52 when in the retracted position, and the pusher pawl 58 moves forward together with the linear advance / retreat member 57. When it moves, it engages with the receiving claw 52 and moves the upper running portion 45a through the receiving claw 52 by a stroke equal to the arrangement interval of the pushers 46, so that the entire chain 45 is rotated. pusher 46 is pressed by traversing the timber element rows a, located on the line L is received by the wood element row a in the forward stop position of the pusher pawl 58 is fed into position on the clamping line L ₁ It will be.

  When the pusher claw 58 returns to the retreat limit position, the standing pusher claw 58 moves away from the engaged receiving claw 52 and interferes with the receiving claw 52 at the subsequent position during the movement, When the pusher claw 58 is in contact with the receiving claw 52, the pusher claw 58 passes below the receiving claw 52 by declining on the lower pivot point as a fulcrum, and returns to the standing posture by the spring 59 in the retracted position. Will do.

As described above, the lateral feed mechanism 18 reciprocally moves the endless chain 45 at a pitch equal to the arrangement interval of the pushers 46 by the reciprocating motion of the rodless cylinder 54, thereby receiving the wood element row A and receiving line L. it is intended to transverse feed on pressing the line L ₁ from the top.
In order to cope with a change in the width dimension of the wood element row A, the lateral feed mechanism 18 is a male screw supported by a fixed female plate 56 on a lower female screw member 60 of a movable plate 56 to which a rodless cylinder 54 is attached as shown in FIG. When the shaft 61 is screwed, the adjustment shaft 62 attached along the length direction of the support frame 19 and the male screw shaft 61 are interlocked by the bevel gear 63, and the adjustment shaft 62 is rotated by the handle 64 shown in FIG. The rodless cylinder 54 in each lateral feed mechanism 18 moves in synchronism with the lateral feed direction of the pusher 46 so that the backward limit position of the pusher pawl 58 relative to the receiving pawl 52 of the chain 45 can be changed. ing.

For example, when the width dimension of the wood element row A is wider than a prescribed value, the backward limit position of the pusher claw 58 is set to the rear of the prescribed position, and the wood element row A on the receiving line L is increased by the width. by shifting the extrusion start position behind the tip end edge of the lateral feeding wood element rows a to ensure a constant position on the clamping line L _1.

  FIGS. 11A and 11B show a second example of the lateral feed mechanism 18 in which a servo motor 65 is used as an intermittent drive means for the chain 45 in place of the rodless cylinder 54. Note that the same parts as those in the first example are denoted by the same reference numerals and are not described.

  In this second example, the sprocket 47 meshing with the endless chain 45 is intermittently driven by the servo motor 65, the distance traveled by the endless chain 45 is calculated and instructed to the servo motor 65, and the lateral movement stroke of the pusher 46 is set. I try to control it.

  The finger joint pressing device according to the present invention is configured as described above. Next, the operation of the device using the transverse feed mechanism 18 of the first example will be described.

  When the finger joint b is processed at both ends of the lengthwise direction and the wood element a with the adhesive applied to the finger joint b is fed from the feeding mechanism toward the temporary press-fitting device 3, the finger joint b shown in FIG. As described above, the press-clamping device 11 stands by while the shutter 24 is lowered to the lower limit, and the upper feed roll 15 of the temporary press-fitting device 3 is rotated by detecting the lower limit of the elevating cylinder 28.

  In the lateral feed mechanism 18, the pusher pawl 58 of the rodless cylinder 54 stands by at the retreat limit position.

  The wood elements a sent from the feeding mechanism to the temporary press-fitting device 3 in FIG. 10 are fed by the upper and lower feeding rolls 14 and 15 while being pressed against the brake 16, so that each wood element a has a difference from the feeding speed of the feeding mechanism. The finger joint b is temporarily press-fitted to form a wood element row A to which the wood elements a are connected, and the finger joint b is supplied onto a receiving line L serving as a regular cutting portion of the pressing device 11.

  As shown in FIG. 4A, the wood element row A sent onto the receiving line L advances in the length direction while being pressed and guided by the shutter 24 and the leaf spring 30 attached to the shutter 24. When the set length determining sensor 23 detects the tip of the element row A, the feeding mechanism is stopped, and the dimension cutting saw 25 moves up and down with respect to the stopped wood element row A, and the wood element row A is set. Cut to a standard length.

  When the cutting of the wood element row A is completed, as shown in FIG. 4B, the shutter 24 and the leaf spring 30 are lifted by the contraction of the lift cylinder 28, the cylinder 42 is extended, and the lift stopper 32 is lowered. The rodless cylinder 54 of the lateral feed mechanism 18 moves forward by detecting the lower limit position 42, the upper limit of the shutter 24, and the upper limit of the lifting cylinder 38 of the upper material presser 31.

As shown in FIG. 4B, when the pusher claw 58 of the rodless cylinder 54 moves forward from the retreat limit position, the pusher claw 58 is located on the upper running portion 45a of the endless chain 45. When the endless chain 45 is engaged and pushed, the upper travel part 45a moves by the stroke of the rodless cylinder 54, and the pusher 46 of the upper travel part 45a attached to the chain 45 is moved. There forward, the wood element sequence a that has been cut to a fixed size length on receiving line L shown in FIG two-dot chain line, thereby traversing movement over the clamping line L ₁ as shown in Fig solid.

  At this time, at the position where the pusher 46 has advanced to the advance limit of the rodless cylinder 54, the rod of the chain positioning cylinder 66 rises, and its tip fits into the hole of the chain positioning tool 53, and the position of the chain 45 at the time of pressure clamping The occurrence of deviation will be prevented.

  When the pusher claw 58 of the rodless cylinder 54 moves forward to the forward limit position and the sensor detects this forward limit, the lift cylinder 28 extends and the shutter 24 drops to the lower limit as shown in FIG. When the lowering limit of the cylinder 28 is detected, the feeding mechanism is actuated to start feeding the next waiting wood element row A onto the receiving line L.

  When the pusher pawl 58 of the rodless cylinder 54 moves forward to the forward limit position and the forward limit lead switch of the cylinder 54 operates, the pusher pawl 58 of the rodless cylinder 54 returns to the backward limit position. The pusher claw 58 that stands up is separated from the receiving claw 52 that has been engaged, and interferes with the receiving claw 52 that is in the subsequent position during the movement. When it comes into contact, the lower pivot point falls on the fulcrum and escapes, returning to the standing posture at the retreat limit position.

  When the pusher claw 58 of the rodless cylinder 54 moves forward to the forward limit position and the forward limit lead switch of the cylinder 54 is actuated, the upper material presser 31 is lowered by the extension of the cylinder 38 as shown in FIG. While pressing the upper surface of the wood element row A with the pressing member 31, the lifting stopper 32 is positioned on the side surface of the wood element row A to prevent the buckling of the wood element row A during pressing and The stopper 34 is also lowered together with the material presser 31.

Upon detecting the descent of the elevating stoppers 32 and the upper material presser 31, wood element rows A sent is cut into fixed-length in clamping line L ₁ is pressurized in the column direction at an elongation of clamping cylinder 33, the When the tip of the wood element row A comes into contact with the protrusion 34a of the stopper 34 shown in FIG. 9, the pressure is applied between the pressing cylinder 33 and the stopper 34 in FIG. 1, and the press-fit adhesion of the finger joint b is completed. A wood joined body is obtained.

As described above, when the press-fitting adhesion of the finger joint b is completed and the retraction of the clamping cylinder 33 is detected, the cylinders 38 and 42 are contracted, and the elevating stopper 32 and the upper material presser 31 are returned to the ascent limit position. Upon detecting the return to the raised limit position, raised to the upper descending limit shutter 24, by lateral feed movement for the next timber element sequence a that standard dimension are cut to a length of the receive line L on clamping line L ₁ The wood joined body in which the press-fitting adhesion of the finger joint b is completed is pushed by the pusher 46 and discharged out of the machine at the time of the lateral feed process of the next wood element row A as shown in FIG.

Said transverse feed mechanism 18, and the upper surface of the upper running portion 45a of the endless chain 45, since the bottom surface of the receiving line L and clamping the line L ₁ is in the same plane, finger joints b in clamping the line L ₁ upon stuffing bonding process, no generation of projections onto receiving line L, Thus, when the press-fitting bonding finger joints b on clamping the line L ₁ is completed, the next timber element sequence on the receiving line L A can be fed, and the waiting time for feeding the next wood element row A onto the receiving line L can be shortened, thereby improving the productivity of the wood joined body.
