Description

  The present invention relates to a wood pressure processing machine, and more particularly to a wood pressure processing machine that compresses wood into compressed wood by applying a compressive force in the radial direction of the wood.

  Conventionally, wood used for building materials or the like has been subjected to wood treatment in which a treatment liquid such as a preservative or a flame retardant is infiltrated in order to maintain the quality of the wood.

  And in order to make this processing liquid penetrate | infiltrate favorably to wood, the method of immersing in a processing liquid after compressing wood into compressed wood is also employ | adopted generally. In this case, the compressed wood immersed in the treatment liquid absorbs the treatment liquid when restored from the compressed state. As a result, the treated liquid can be satisfactorily absorbed by the compressed wood.

  In order to compress wood into compressed wood, a wood pressure processing machine that includes a compression roller that is rotated by a driving force supplied by a drive unit and compresses the wood in a central direction is generally used.

  When this wood pressure processing machine is used, the wood is compressed into compressed wood by being compressed while being sent in one direction by a rotating compression roller.

  However, in the above-described wood pressure processing machine, when the rotation speed of the compression roller is high or when the contact surface of the compression roller with the wood is slippery, the wood may not follow the rotation of the compression roller. . In this case, since slip occurs between the outer peripheral surface of the compression roller and the surface of the wood, there is a possibility that the surface of the wood may be scratched or compressed, and the quality of the compressed wood may be deteriorated.

  Moreover, when the above-mentioned wood pressure processing machine is provided with a plurality of compression rollers, there may be a deviation in the peripheral speed of rotation of the plurality of compression rollers.

  In this case, it is difficult to smoothly pass the wood that is moved by the rotation of the compression roller, and slipping easily occurs between the surface of the wood and the rotating compression roller. As a result, scratches, uneven compression, and the like occur on the surface of the wood, which may reduce the quality of the compressed wood.

  In view of the above circumstances, an object of the present invention is to provide a wood pressure processing machine in which slippage hardly occurs between a compression roller and wood.

The means taken by the present invention to solve the above-mentioned problems are as follows:
“A wood compression device having a compression roller that is rotatably supported and compresses the wood into compressed wood by applying a compressive force in the radial direction of the wood, and a wood feeding device that feeds wood into the wood compression device The wood feeding device includes a support base that supports the wood, and an abutting member that abuts against an end of the wood supported by the support base, and is arranged in the axial direction of the wood by a feed screw mechanism. A timber transport body that is driven to move, and the timber transport body displaces the contact member between a contact position that contacts the wood and a non-contact position that does not contact the wood. A displacement mechanism, wherein the displacement mechanism positions the abutting member at the abutting position when the timber transporter moves closer to the timber compressing device, and the timber transporter is moved from the timber compressing device. Before moving away Wood pressure processing machine, characterized in that to position in the non-contact position "
It is.

  Here, as the wood compression device, for example, a pair of compression rollers that compress wood from the vertical direction to the center direction and another pair of compression rollers that compress the wood from the left-right direction to the center direction are alternately arranged in a freely rotatable manner. Can be illustrated.

  In the wood pressure processing machine configured as described above, the wood is sent to the wood compression device by the wood feeding device. Since the compression roller of this wood compression device is rotatably supported, it rotates by contact with the wood sent to the wood compression device. As a result, the peripheral speed of the compression roller and the speed at which the wood moves can be made substantially the same. Therefore, according to the wood pressure processing machine of the said structure, it can be set as the wood pressure processing machine with which a slip hardly arises between a compression roller and wood.

  Further, in the wood pressure processing machine having the above-described configuration, the compression roller of the wood compression device is rotatably supported, so that a drive unit for supplying drive force is not required. Therefore, according to the wood pressure processing machine having the above-described configuration, the structure of the wood compression apparatus can be simplified.

Further, in the wood pressure processing machine having the above-described configuration, the wood feeding device pushes and moves the wood in the axial direction by moving and driving the wood transport body in contact with the end of the wood in the axial direction of the wood. Thereby, the wood is fed into the wood compression device.

  And in the wood pressure processing machine of the said structure, the feed screw mechanism is employ | adopted as what drives a wood conveyance body to move. Here, the feed screw mechanism includes a screw shaft and a screw member that is threaded through the screw shaft and attached to the wood transfer body. By rotating the screw shaft in the circumferential direction, a propulsive force is applied to the screwing member, and the screw shaft and the screwing member can be relatively moved along the screw shaft.

  As a result, the wood transport body can be moved forward with respect to the wood compressing device to feed the wood, and then retracted with respect to the wood compressing device so that it can come into contact with the end of the new wood. It becomes. Therefore, according to the wood pressure processing machine having the above-described configuration, the wood feeding device can continuously feed wood to the wood compression device.

  Further, in the wood pressure processing machine having the above-described configuration, in the wood feeding device, the power required to move and drive the wood transfer body is reduced by adopting a feed screw mechanism as a drive for moving the wood transfer body. It becomes possible. Therefore, according to the wood pressure processing machine of the said structure, it can be set as the wood pressure processing machine which reduced the required motive power.

  As described above, when the feed screw mechanism is adopted as the drive for moving the wood transport body, the wood feed device can continuously feed the wood into the wood compression device by moving the wood transport body forward and backward. . In this case, the work of supporting the new timber on the support after the timber has been sent to the timber compressing device is to transfer the timber to the timber compressing device in order to avoid collision between the new timber and the timber transport. It must be done after the work of retracting the body to a state where it can abut against the end of the new wood is completed.

  In the wood pressure processing machine having the above configuration, when the wood transport body is advanced with respect to the wood compression device, the contact member is located at the contact position. Thereby, the timber supported by the support stand is sent into the timber compression apparatus. When the wood transport body is moved backward with respect to the wood compression device, the contact member is located at the non-contact position. Thereby, a timber transport body does not contact the timber supported by the support stand.

  As a result, after one piece of wood is sent to the wood compression device, the work to support the new wood on the support stand and the work to retreat the wood transporter that has sent the wood to the wood compression device are performed at the same time. Time can be reduced. Therefore, according to the wood pressure processing machine having the above-described configuration, it is possible to efficiently perform the work of feeding wood to the wood compression apparatus.

  As described above, according to the wood pressure processing machine of the present invention, it is possible to provide a wood pressure processing machine in which slippage hardly occurs between the compression roller and the wood.

As shown in FIGS. 3 to 5, the wood feeding device 7 includes a support base 4 for supporting the wood 2 and a pair of wood transport bodies 5a for moving the wood 2 supported by the support base 4 in the axial direction. , 5b and a pair of feed screw mechanisms 6a, 6b for moving and driving the pair of wood transport bodies 5a, 5b in the axial direction of the wood 2.

  The support base 4 of the wood feeding device 7 will be described in more detail.

  As shown in FIG. 3, the support table 4 supports the wood 2 fed into the wood compression device 3 in front of the pressure unit 10, and includes a plurality of support columns 12 that support the wood 2 from below. It is composed.

  Next, the wood transfer body 5a of the wood feeding device 7 will be described in more detail. The wood transfer body 5b has the same configuration as the wood transfer body 5a, and thus the description thereof is omitted.

  As shown in FIGS. 3 to 5, the wood transport body 5 a includes a contact member 13 a that can contact the wood 2, a base member 14 that is disposed on the side of the wood 2 and supports the contact member 13 a, The slide member 15 includes a slide means 15 that slidably supports the base member 14 along the axial direction of the wood 2, and a displacement mechanism 16 that displaces the contact member 13 a relative to the base member 14.

  As shown in FIG. 5, the contact member 13a is formed in a substantially rod shape, and two slide shafts 17 project from the side surface. The base member 14 is formed with a bearing (not shown) through which the slide shaft 17 of the abutting member 13a is inserted, and the slide shaft 17 is slidably supported. As shown in FIG. 3, the slide means 15 is supported by a pair of support pillars 18 erected from the installation base F of the wood feeding device 7, and is provided with a rail 19 and a base member 14 arranged in the horizontal direction. And a slide member 20 attached to the rail 19. A roller 21 that can rotate along the rail 19 is attached to the base 20. As a result, the base 20 can move stably along the rail 19 in the horizontal direction.

  The displacement mechanism 16 includes a shaft 22 having one end attached to the side surface of the contact member 13a, a fluid pressure cylinder 23 attached to the other end of the shaft 22 and moving the shaft 22 in the axial direction, and a fluid pressure cylinder. And a fluid pressure circuit (not shown) for determining and operating the operation direction. When the fluid pressure cylinder 23 is operated in the pushing direction, the contact member 13 a is pressed in a direction away from the base member 14 via the shaft 22 and displaced to a contact position capable of contacting the wood 2. On the other hand, when the fluid pressure cylinder 23 is operated in the pulling direction, the contact member 13a is pulled in a direction approaching the base member 14 via the shaft 22 and is displaced to a non-contact position that does not contact the wood 2. .

  Next, the feed screw mechanism 6a of the wood feeding device 7 will be described in more detail.

  As shown in FIGS. 3 and 4, the feed screw mechanism 6a includes a screwing member 24a attached to the base 20 of the wood transfer body 5a and a lower part of the rail 19, and penetrates the screwing member 24a. The screw shaft 25a is screwed, and the drive unit 26 is connected to the screw shaft 25a and serves as a drive source for rotating the screw shaft 25a.

  In the feed screw mechanism 6a, when the drive unit 26 is driven, the screw shaft 25a starts to rotate. The rotational movement of the screw shaft 25a is converted into a linear movement of the screwing member 24a that is screwed into the screw shaft 25a. Thereby, the screwing member 24a can be advanced and retracted along the axial direction of the screw shaft 25a. Therefore, the wood transfer body 5a can be advanced and retracted along the axial direction.

  The feed screw mechanism 6b uses the same drive unit 26 as the feed screw mechanism 6a described above, and the other configurations have the same configuration as the feed screw mechanism 6a, and thus the description thereof is omitted. To do.

  Next, the drive unit 26 that supplies drive force to the feed screw mechanisms 6a and 6b will be described in more detail.

  As shown in FIGS. 3 and 4, the drive unit 26 includes a motor 27, a motor-side sprocket 28 that outputs the rotational force of the motor 27, and screw shaft-side sprockets 29a fixed to the screw shafts 25a and 25b. 29b, a chain (not shown) connecting the motor side sprocket 28 and the screw shaft side sprockets 29a and 29b, and between the screw shaft 25a and the screw shaft side sprocket 29a or between the screw shaft 25b and the screw shaft side sprocket 29b. It has a reverse gear (not shown) interposed on one side.

  As described above, the drive unit 26 has the reverse gear interposed only between the screw shaft 25a and the screw shaft side sprocket 29a or between the screw shaft 25b and the screw shaft side sprocket 29b. Thereby, the screw shaft 25a and the screw shaft 25b always rotate in the opposite directions. As a result, the wood transport body 5b moves in a direction opposite to the wood transport body 5a.

  The wood feeding device 7 is provided with control means for controlling the motor 27 of the drive unit 26 and the fluid pressure circuit of the displacement mechanism 16 based on preset setting conditions. Specifically, the control means controls the motor 27 and the fluid pressure circuit based on a signal from a detector that detects the movement position of the wood transfer bodies 5a and 5b, such as a limit switch (not shown). Not). The screw shaft side sprockets 29a and 29b are provided with clutches that can transmit or block the rotation of the motor 27. By the control means and the clutch, the wood transfer bodies 5a and 5b are independently driven to move based on the set conditions.

  In this embodiment, by setting the control means in advance, the wood transporters 5a and 5b are on the opposite side of the wood compression device 3 with the support base 4 interposed therebetween (hereinafter referred to as a feed start position). When the wood transfer body 5a moves between the support table 4 and the same side as the wood compression device 3 (hereinafter referred to as a feed completion position), and further moves to the feed start position, a fluid pressure cylinder It is assumed that the fluid pressure cylinder 23 is actuated in the pulling direction when the actuator 23 is actuated in the pushing direction and moved to the feeding completion position.

  Next, the operations of the first compression rollers 8a and 8b and the second compression rollers 9a and 9b of the wood compression device 3 when the wood 2 is fed will be described in detail with reference to FIGS.

  First, before use of the wood compression device 3, the interval between the first compression rollers 8a and 8b and the interval between the second compression rollers 9a and 9b are set to a predetermined interval so as to perform compression processing to a desired external dimension as compressed wood. Keep it. Specifically, the wood pressure device 3 can change the interval between the first handle 50 and the second compression rollers 9a and 9b, which can change the interval between the first compression rollers 8a and 8b. A second handle 60 is provided on the outer surface of the cover 11, and by rotating the first handle 50 and the second handle 60, between the first compression rollers 8a and 8b and the second compression rollers 9a and 9b. Change the interval between.

  In addition, as a dimension of the interval to be set, in order to allow the wood 2 to be easily received in the pressure unit 10, the interval between the pair of first compression rollers 8a and 8b installed at the left end is: It is preferable to set the interval substantially equal to the diameter of the wood 2. And in order to suppress the damage of the timber 2, the space | interval etc. between subsequent 2nd compression rollers 9a and 9b are gradually narrowed toward the advancing direction of the timber 2, and the 1st compression roller 8a installed in the right end, It is preferable to set the interval between 8b and the interval between the second compression rollers 9a and 9b to a desired external dimension as compressed wood.

  The wood 2 fed from the left side by an external force moves in the traveling direction between the first compression rollers 8a and 8b installed at the left end in the pressure unit 10. At this time, the first compression rollers 8 a and 8 b start to rotate by contact with the wood 2. The wood 2 that has passed between the pair of first compression rollers 8a and 8b moves between the second compression rollers 9a and 9b. Then, like the first compression rollers 8a and 8b, the second compression rollers 9a and 9b also start to rotate in accordance with the movement of the wood 2. Thereafter, the first compression rollers 8a and 8b and the second compression rollers 9a and 9b arranged side by side are rotated by contact with the wood 2 moving in the traveling direction. As described above, the first compression rollers 8a and 8b and the second compression rollers 9a and 9b of the wood compression device 3 rotate.

  Note that, as described above, the compression roller 8a and the like included in the wood compression device 3 in the present embodiment have the V-shaped groove portions 30 and 40 formed in the outer peripheral surfaces thereof. For this reason, the upper surface and the lower surface of the wood 2 are compressed into a surface having a 135 ° corner by being compressed by the outer peripheral surfaces of the first compression rollers 8a and 8b (see FIG. 2A). Further, the left surface and the right surface of the wood 2 in FIG. 2 are compressed into a surface having a corner portion of 135 ° by being compressed to the outer peripheral surfaces of the second compression rollers 9a and 9b (see FIG. 2B). ). Thereby, the wood 2 is compressed into a compressed wood having an octagonal cross section.

  Next, the operation of the wood feeding device 7 will be described based on FIG. 3 and FIG. As described above, it is assumed that the control unit is set in advance.

  First, the wood transport body 5a is positioned at the feed start position on the screw shaft 25a, and the wood transport body 5b is positioned at the feed completion position on the screw shaft 25b (see FIG. 5A). Next, the motor 27 starts rotating a predetermined number of times in one direction based on the setting of the control means. By this rotation, the wood transport body 5a moves to the feed completion position, and at the same time, the wood transport body 5b moves to the feed start position (see the arrow in FIG. 5B). At this time, the contact member 13a of the wood transport body 5a is located at the contact position, and the contact member 13b (see FIG. 5) of the wood transport body 5b is located at the non-contact position.

  The wood transfer body 5a that has moved to the feeding completion position stops moving and displaces the contact member 13a to the non-contact position based on the installation of the control unit. Moreover, the wood transport body 5b moved to the feed start position stops moving and displaces the contact member 13b to the contact position based on the installation of the control unit.

  And when each of the timber transporters 5a and 5b moves to the feed completion position or the feed start position, the motor 27 switches the rotation direction based on the setting of the control means and starts to rotate in the reverse direction. Thereby, the wood transfer body 5a is moved to the feed start position in a state where it is displaced to the non-contact position of the contact member 13a, and at the same time, the wood transfer body 5b is displaced to the contact position of the contact member 13b. In this state, move to the feed completion position. Thereafter, the wood transporters 5a and 5b repeat the above-described series of operations.

  Next, operation | movement of the whole wood pressure processing machine 1 of this embodiment is demonstrated.

  First, as shown in FIGS. 3 and 5A, the wood 2 is supported on the support base 4 of the wood feeding device 7. In addition, as a method of installing wood on the support base 4, it may be a method in which an operator manually installs wood, or a method using a separate device.

  Then, the wood feeding device 7 starts the above-described operation based on the setting of the control unit (see FIG. 5B), and the wood 2 moves the wood in a state where the contact member 13a is located at the contact position. It is pushed and moved by the body 5 a and fed into the wood compression device 3.

  When the wood 2 is fed, the first compression rollers 8a and 8b and the second compression rollers 9a and 9b of the wood compression device 3 start the above-described operation. Thereby, the wood 2 moves in the advancing direction between the rotating first compression rollers 8a and 8b and between the second compression rollers 9a and 9b while being compressed by the compression surface of each compression roller.

  Then, the wood transport body 5a that has moved to the feed completion position and the wood transport body 5b that has moved to the feed start position stop moving. At this time, the wood 2 that has been moved in accordance with the movement of the wood transfer body 5 a stops moving in the pressure unit 10.

  Further, the contact member 13a of the wood transport body 5a that has stopped moving is displaced to the non-contact position, and the contact member 13b of the wood transport body 5b that has stopped moving is displaced to the non-contact position. At the same time, new wood is installed on the support base 4.

  Then, the timber transport body 5a and the timber transport body 5b resume moving in the opposite direction, and the new timber supported by the support base 4 is the timber transport body 5b in a state where the abutting member 13b is located at the abutting position. And is fed into the wood compression device 3.

  The new wood fed into the wood compression device 3 moves while pushing the wood 2 that has stopped moving in the pressurizing unit 10 in the traveling direction. As a result, the wood 2 is pushed out of the pressure unit 10. The new wood is compressed by the first compression rollers 8a and 8b and the second compression rollers 9a and 9b as in the case of the wood 2.

  The wood 2 is compressed into compressed wood by the series of operations described above. And the wood pressure processing machine 1 of this embodiment can perform the compression process of wood continuously by repeating this series of operation | movement.

  By the way, in the case of the wood pressure processing machine 1 of the present embodiment, when the use is finished, the wood that is finally fed into the wood compression device 3 remains in the pressure unit 10. Therefore, an alternative material may be used instead of the wood that remains in the pressurizing unit 10. Note that this alternative material is pushed out of the pressurization unit 10 by the wood first fed into the wood compression device 3 when the wood pressure processing machine 1 is used again.

  Thus, according to the wood pressure processing machine 1 of the present embodiment, the wood is provided with the first compression rollers 8a and 8b and the second compression rollers 9a and 9b that are rotatably supported by the wood. 3 is compressed into compressed wood. For this reason, each compression roller is rotated by contact with the wood 2 fed by the wood feeding device 7. As a result, the peripheral speed of the compression roller and the speed at which the wood 2 moves can be made substantially the same. Therefore, it can be set as the wood pressurization processing machine 1 with which a slip hardly arises between the compression roller 8a etc. and the wood 2. FIG.

  In particular, as described above, when a conventional wood pressure processing machine is provided with a plurality of compression rollers that are rotationally driven, the circumferential speed of rotation of the plurality of compression rollers also causes a shift. There could be slippage between the surface of the wood and the rotating compression roller. On the other hand, in the wood pressure processing machine 1 according to the present embodiment, although the plurality of compression rollers are provided, the rollers themselves are not rotationally driven, so that it is difficult for slippage to occur between the compression rollers 8 a and the wood 2. The wood pressure processing machine 1 can be obtained.

  Further, in the wood feeding device 7, feed screw mechanisms 6a and 6b are employed as the ones for moving and driving the wood transport bodies 5a and 5b. And the wood compression apparatus 3 becomes a structure which does not require motive power. Thereby, it becomes possible to reduce the power required to move and drive the wood transporter, and the wood pressure processing machine 1 can reduce the required power.

  Furthermore, in this embodiment, the two timber transport bodies 5a and 5b are used, and the timber transport bodies 5a and 5b alternately feed the timber into the timber compressing device 3. As a result, it is possible to use the time for one of the timber transporters to move from the feed completion position to the feed start position for the time for the other timber transporter to feed the timber, and to efficiently compress the wood. it can.

  Further, when the wood transfer bodies 5a and 5b move from the feed completion position to the feed start position, the contact members 13a and 13b are positioned at the non-contact positions by the displacement mechanisms 16 of the wood transfer bodies 5a and 5b. Thereby, the timber transporter can move from the feed completion position to the feed start position without obstructing the movement of the timber.

  The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the embodiments, and as described below, improvements and designs can be made without departing from the scope of the present invention. It can be changed.

  That is, in the wood feeding device 7 of the wood pressure processing machine 1 of the present embodiment, an example having two wood transport bodies is illustrated, but the present invention is not limited to this. It does not matter.

  Moreover, in the drive part 26 of the wood pressure processing machine 1 of this embodiment, in order to drive the wood transporters 5a and 5b to move in the opposite directions, between the screw shaft 25a and the screw shaft side sprocket 29a or between the screw shaft 25b and the screw. Although the reverse rotation gear is interposed between either one of the shaft side sprockets 29b and the screw shaft 25a and the screw shaft 25b are rotated in reverse, the present invention is not limited to this. For example, in the motor side sprocket 28 and the screw shaft side sprockets 29a and 29b connected by the chain, the screw shaft side sprockets 29a and 29b are positioned so as to be opposed to each other with the chain interposed therebetween. By changing the screw shafts 25a and 25b, the screw shafts 25a and 25b may be reversely rotated. Further, as the screw shaft included in the wood transport body 5b, the wood transport bodies 5a and 5b are driven to move in the reverse direction by using the screw shaft formed on the reverse screw of the screw shaft 25a included in the feed screw mechanism 6a. It doesn't matter.

  Moreover, although the thing provided with two or more compression rollers was illustrated in the wood compression apparatus 3 of the wood pressure processing machine 1 of this embodiment, it is not limited to this. For example, when the compression ratio desired as the compressed wood is low, or when the length of the compressed wood is short, the number of compression rollers included in the wood compression device 3 is at least one. It does not matter as long as it is provided.

Above, the timber infeed device 7 of timber pressure processing machine 1 of the present embodiment, the contact member 13a, two-body of the timber conveying member 5a with 13b, is exemplified ones having a 5b, then, the present invention The thing using the wood feeder 7 as shown in FIG.6 and FIG.7 which is not directly related to FIG. 7 is illustrated.

  The operation when this wood feeding device 7 is used will be described.

  First, the first transfer body 51a moves from the feed start position to the feed completion position while gripping the vicinity of the end of the rod-like body 52 on the wood 2 side (see FIG. 7A), and then moves the gripping body. Release (see FIG. 7B). Thereby, the rod-shaped body 52 pushes and moves the wood 2 abutting on the end toward the wood compressing device 3. As a result, the wood 2 is fed into the wood compression device 3 and compressed by the rotating first compression rollers 8a and 8b and the second compression rollers 9a and 9b in the same manner as the wood 2 of the present embodiment.

  And the 2nd transfer body 51b is the state which hold | gripped the vicinity of the edge part on the opposite side to the edge part vicinity which the 1st transfer body 51a of the rod-shaped body 52 moved with the 1st transfer body 51a (FIG.7 (b)). (Refer to FIG. 7 (c)). Thereby, the rod-shaped body 52 is fed into the wood compression device 3 and pushes the wood 2 remaining in the pressurizing unit 10 to the outside of the pressurizing unit 10. By the above operation, the wood 2 is compressed into compressed wood.

  According to the wood feeding device 7 in this case, the wood 2 is fed into the wood compressing device 3 and further pushed out from the pressurizing part 10 of the wood compressing device 3. Thereby, when the use of the wood pressure processing machine 1 is finished, the wood does not remain in the wood compression device 3. Therefore, it is possible to provide an efficient wood pressure processing machine 1 that does not generate waste wood.

  In this case as well, the screw shafts 25a and 25b are rotated by using the common motor 27 by providing the screw shafts 25a and 25b with a clutch capable of transmitting or blocking the rotation of the motor. It is possible to employ the feed screw mechanisms 6a and 6b in the present embodiment.
