  According to the wood rollover device of the present invention, when the vertical portion is tilted toward the L-shaped back surface, the bent portion is moved in the direction opposite to the tilting direction. As a result, the wood received by the horizontal portion is rolled over while moving the lower end corner portion on the vertical portion side in the direction opposite to the falling direction. Therefore, in addition to the force to slide toward the back side of the wood, a force to move in the opposite direction to the back side is also applied, and when it rolls over 90 degrees, it starts to slide back and roll out greatly. There is nothing to do. In addition, as a result of the lower end of the back side being moved in the direction opposite to the falling direction, it is possible to roll over 90 degrees without largely moving to the back side from the position before rollover. In this way, it is possible to quickly execute the rollover operation because the sliding and rolling of the wood can be prevented.

  According to the wood rollover device also having the configuration of (2A) and (2B), the L-shaped cradle is supported so that the vertical side link member and the horizontal side link member are in a C shape with respect to the main body. Therefore, when the bent portion is moved in the direction opposite to the tilting direction, the L-shaped cradle can be caused to rotate so that the vertical portion falls to the back side while the horizontal portion stands. At this time, the bent portion moves in the direction opposite to the falling direction, so that the wood can be rolled over by 90 degrees without largely moving the wood to the back side, and further without sliding down or rolling down.

  According to the wood rollover device having the configurations of (3A) and (3B), when a force is applied to rotate the bent portion link member in the direction opposite to the falling direction, the vertical portion of the L-shaped cradle is It is possible to execute rotation for raising the horizontal portion while falling in the direction.

  When the piston rod of the fluid cylinder is moved forward, the main body swings to the tip side as a whole while turning the tip upward, and when the piston rod of the fluid cylinder is moved backward, the body turns as a whole while turning the tip downward. Swing to the original side. As a result, when the main body is rotated to a horizontal state, the L-shaped cradle stands up so as to wrap around in the distal direction. The L-shaped cradle turns the timber by tilting the vertical part to the back side, so even if the back side of the timber is away from the vertical part in the state before the rollover, at an early stage during the rollover Abut. Therefore, it is only necessary to prevent interference with the maximum width of wood. After the rollover is completed, when the piston rod of the fluid cylinder is retracted, the main body is retracted so that the tip is rotated downward while swinging to the original side as a whole. Accordingly, the L-shaped cradle rotates downward while being separated from the tumbled wood, and can be retracted without interference.

  According to the present invention, it is possible to roll over quickly and reliably without spilling wood from an L-shaped cradle.

  Examples to which the present invention is applied will be described below.

  As shown in FIGS. 1 and 2, the wood rollover device 1 of this embodiment is installed at a wood discharge position of a precut processing facility in which a roller conveyor 10 and a caterpillar conveyor 20 are installed. In the following description, when distinguishing front and rear, the lower side in FIG. 2 is referred to as “front” and the upper side is referred to as “rear”.

  The roller conveyor 10 has a plurality of roller units 11 to 16 arranged in series. The plurality of roller units 11 to 16 are arranged in a line with their centers aligned so that wood can be fed vertically and with a predetermined space between the units. Each of the roller units 11 to 16 is a free roller, and it is possible to support the wood conveyed by a vertical feeding device (not shown) from below with a roller surface and move it in the vertical direction. Yes.

  The caterpillar conveyor 20 has a plurality of caterpillar units 21 to 25 arranged in parallel. The plurality of caterpillar units 21 to 25 are installed so that the wood can be laterally fed by inserting the tip between the roller units 11 to 16. Moreover, each caterpillar unit 21-25 is connected with the connection rod 26 at the front end side. The connecting rod 26 constitutes a mechanism that is moved up and down by two hydraulic cylinders CYL21 and CYL22 that are installed with a space left and right. The hydraulic cylinders CYL21 and CYL22 are normally in a state in which the connecting rod 26 is lowered, and after the rollover by the wood rollover device 1 is completed, the connecting rod 26 is raised and the wood is lifted at the tip of each of the caterpillar units 21-25. The operation received from the roller type conveyor 10 is executed. Further, the sprocket 27 provided on the base side of each of the caterpillar units 21 to 25 has a common drive shaft 28 and is driven by a lateral feed motor MT20.

  The wood rollover device 1 has a plurality of rollover units 31 to 35 arranged in parallel. The plurality of rollover units 31 to 35 are installed along the caterpillar units 21 to 25 on either the left or right side of the caterpillar units 21 to 25.

  2 to 5, the wood rollover device 1 includes a front and rear base frame 41 extending in parallel with the caterpillar units 21 to 25, a portal column 42 erected from the front end of the front and rear base frame 41, A front end frame 43 fixed in the middle of the rear end surface of the mold column 42 and extending in the left-right direction, and a left and right base frame installed so as to extend in the left-right direction so as to be orthogonal to the front-rear base 41 in front of the portal column 42 44 is provided. And each rollover unit 31-35 is attached to the bracket 51 for rotation fixed to the upper surface of the front-end frame 43 so that rotation is possible, and pierces in the left-right direction on both sides of the portal column 42 It is integrated by the square frame 36 delivered in the same manner.

  In addition, an elevating front bracket 52 is attached to the rear upper portion of the portal column 42 positioned inside the rollover units 31 and 35 at both ends, and the rectangular frame 36 at a position corresponding to the rear of the elevating front bracket 52. A rear bracket 53 for raising and lowering is also attached to the upper surface. The front and rear brackets 52 and 53 for raising and lowering are connected by an upper link bar 54 so as to be joined at both ends. A lower swinging member 56 is attached to the upper surface of the left and right base frames 44 so as to correspond to the rear lifting bracket 53.

A piston rod of hydraulic cylinders CYL31 and CYL32 for raising and lowering the rollover unit is connected to an upper end of the lower swing member 56, and a rack bar 58 installed so as to be parallel to the piston rod is also connected. The rack bar 58 is meshed with a pinion gear 59a attached to a pinion shaft 59 extending in the left-right direction. The rack bar 58 serves to stabilize the swinging motion of the lower swinging member 56 with respect to the operation of the piston rod.

  Each rollover unit 31 to 35 includes a main body 60 attached so that the square frame 36 is pierced, and an L-shaped pedestal 70 attached to the rear end side (front end side) of the main body 60. .

  The main body 60 constitutes a rigid frame 62 in which two left and right side plates 61 are connected at a predetermined interval. The rigid frame 62 has a front end (original side) connected to the pivot bracket 51 via an H-shaped swing member 63. When the piston rods of the hydraulic cylinders CYL31 and CYL32 are retracted, the rollover units 31 to 35 move the lower end of the H-shaped swing member 63 to the original side as shown in FIG. The rigid frame 62 swings to the original side as a whole and has its tip lowered, and when the piston rods of the hydraulic cylinders CYL31 and CYL32 are moving forward, as shown in FIG. The lower end of the moving member 63 moves to the front end side, and the rigid frame 62 is configured to swing to the front end side as a whole and become almost horizontal.

  At this time, as indicated by an arrow in FIG. 5C, the rigid frame 62 swings in the distal direction while rotating clockwise in the drawing. When the hydraulic cylinders CYL31 and CYL32 are moved from the state shown in FIG. 5C to the piston rod retracted state, the rigid frame 62 rotates counterclockwise as shown by the dotted arrow in FIG. 5A. While swinging to the original side as a whole. The reason why the rigid frame 62 is not simply rotated but is pivoted in the front-rear direction is that the middle and the original end are suspended.

  Each rollover unit 31 to 35 is in a piston rod advance state in the piston rod retracted state, as shown in FIG. 5 (A), with the L-shaped pedestal 70 sinking below the roller surface. At this time, as shown in FIG. 5C, the L-shaped pedestal 70 is configured so as to protrude above the roller surface.

  The L-shaped pedestal 70 is composed of a horizontal plate 71 having substantially the same size as the width of the maximum dimension horizontal member that can be processed, and 1/2 of the maximum dimension horizontal material. The horizontal plate 71 extends from the lower end of the vertical plate 72 toward the front (original side) with respect to the valley-side surface of the two L-shaped plates 73. It is a fixed configuration. In the present embodiment, the height of the vertical plate 72 is set to 2/3 of the maximum dimension of the horizontal member.

  Further, the upper end side of the first link member 74 is rotatably connected to the L-shaped plate 73 so as to extend rearward and obliquely downward from the L-shaped bent portion, and the lower end side of the first link member 74. On the other hand, the other end of the second link member 75 is connected to the tip of the rigid frame 62 so that one end of the rigid frame 62 is swingable. Further, the upper end side of the third link member 76 is connected to the L-shaped plate 73 so as to extend from the vertical portion toward the obliquely lower side at the rear (front end side), and obliquely downward from the horizontal portion at the front (original side). The upper end side of the fourth link member 77 is connected so as to extend toward the side, and the lower end sides of the third link member 76 and the fourth link member 74 are connected to the rigid frame 62.

  A drive shaft 81 common to the rollover units 31 to 35 is inserted in the middle of the rigid frame 62. The drive shaft 81 is driven by a rollover motor MT30, and rotates a drive gear 82 attached so as to be positioned at the center between the side plates 61 of the rollover units 31 to 35. Each rollover unit 31 to 35 is provided with a driven gear 84 that transmits the rotation of the drive gear 82 via a chain 83. The driven gear 84 has a diameter larger than that of the drive gear 82 and is attached with a crank arm 85 extending from the center of rotation. One end of a connection rod 86 is connected to the crank arm 85.

  The other end of the connection rod 86 is connected to a position closer to the upper side than the center of the first link member 74. In this embodiment, a position where the length between the upper end connection position and the lower end connection position of the first link member 74 is divided into 4: 6 is defined as a connection portion with the connection rod 86.

  Here, the third and fourth link members 76 and 77 are formed in a frame shape so as to bend the steel plate. In particular, the fourth link member 77 has a window 77a for allowing the connection rod 86 to pass therethrough. The connection rod 86 has a shape in which the vicinity of the insertion position is curved upward so that the connection rod 86 can be operated while avoiding interference with the window 77a.

  Next, operation | movement of the wood rollover apparatus 1 of a present Example is demonstrated. As shown in FIG. 6, the horizontal member W that has been processed and printed is conveyed onto the roller conveyor 10. At this time, the caterpillar type conveyor 20 is in a standby state where it is kept below the upper surface of the roller R. The wood rollover device 1 is also in a state in which the hydraulic cylinders CYL31 and CYL32 are in the piston rod retracted state and the tip of the rigid frame 62 is lowered downward. As a result, the L-shaped pedestal 70 is also tilted rearward (front end side) and is kept below the upper surface of the roller R.

  Next, as shown in FIG. 7, the hydraulic cylinders CYL31 and CYL32 of the wood rollover device 1 are driven to the piston rod advance state. As a result, the upper end of the lower swinging member 56 is pushed rearward (front end side), and the lower link bar 57 rotates toward the front (original side) while pushing up the lower end. Thereby, the raising / lowering front bracket 53 is lifted. As a result, the upper link bar 54 rotates upward, and the rigid frame 63 is rotated horizontally. At this time, the H-shaped swinging member 63 swings so that the lower end swings backward (front end side), thereby smoothly executing a series of operations.

  Thus, when the rigid frame 62 is rotated to the horizontal state, the L-shaped pedestal 70 rises to the upper surface of the roller R while the horizontal plate 72 is horizontal. As a result, the horizontal member W is lifted from the upper surface of the roller R while its weight is supported by the horizontal plate 71 of the L-shaped pedestal 70. At this time, the vertical side plate 72 is vertical and can hold the side surface of the horizontal member W.

  After the horizontal member W is lifted so as to be lifted from the roller R, the roll motor MT30 is driven to rotate the crank arm 85 by 180 degrees. The movement of the L-shaped cradle 70 during this period will be described with reference to FIG.

  Before driving the rollover motor MT30, as shown in FIG. 8A, the crank arm 85 is in a horizontal state with its tip directed rearward (left side in the figure). When the rollover motor MT30 is driven, the crank arm 85 starts to rotate clockwise as indicated by an arrow A in the figure (hereinafter, the direction of rotation / rotation will be described as clockwise or counterclockwise in the figure). ). As a result, the connection rod 86 starts to move so that the original side is lifted diagonally upward (right side in the figure) as indicated by the arrow B.

  At this time, the first link member 74 starts to rotate clockwise around the connecting portion with the connection rod 86. As a result, as shown in FIG. 8B, the second link member 75 whose right end in the figure is connected to the first link member 74 is connected to the tip end (the left end in the figure) connected to the rigid frame 62. ) As shown by the arrow C, and begins to rotate obliquely downward (leftward in the figure). Further, the L-shaped plate 73 having the bent portion connected to the first link member 74 is rotated counterclockwise as a whole as a result of the bent portion being lifted obliquely upward as indicated by an arrow D. start. As the L-shaped plate 73 rotates counterclockwise, the third link member 76 whose upper end is connected to the middle of the vertical side of the L-shaped plate 73 faces the right side in the drawing as indicated by an arrow E. The fourth link member 77, which begins to rotate in the direction of lowering the upper end and is connected to the vicinity of the end of the horizontal side of the L-shaped plate 73, also has its upper end toward the right side of the figure as indicated by the arrow F. Begins rotating in the direction of lifting.

  Thus, the L-shaped plate 73 performs an operation of raising the bent portion obliquely upward on the right side in the figure and tilting the vertical side plate 72 toward the left side in the figure and raising the horizontal side plate 71 toward the left side in the figure. During this time, the bent portion is moved in the direction opposite to the direction of falling. When the crank arm 85 rotates 180 degrees, as shown in FIG. 8C, the vertical plate 72 is turned over 90 degrees so that the horizontal plate 71 becomes horizontal and the horizontal plate 71 becomes vertical. At this time, the third link member 76 rotates counterclockwise as indicated by the arrow G while the crank arm 85 rotates from 90 degrees to 180 degrees.

Thus, as shown in FIG. 9, the horizontal member W is rolled over by 90 degrees. Then, as shown in FIG. 10, the hydraulic cylinders CYL 21, CYL 22 are driven to raise the tip of the caterpillar conveyor 20 , so that the roll member W in a rollover state is received from the wood rollover device 1.

  When the rollover and delivery of the horizontal member W are thus completed, the hydraulic cylinders CYL31 and CYL32 of the wood rollover device 1 are driven to lower the rigid frame 62 to a position where the tip end is lowered in the initial state. At this time, since the rigid frame 62 swings counterclockwise as a whole and swings to the original side, the L-shaped pedestal 70 rotates downward while being separated from the horizontal member W to avoid interference. Is done. When the rigid frame 62 is returned to the initial state in this way, the rollover motor MT30 is reversely rotated to return the L-shaped cradle 70 to the initial state. In addition, you may rotate 180 degree | times to the same direction.

  Then, the transverse feed motor MT20 is rotated, and the horizontally placed horizontal member W is discharged by transverse feed. At this time, since the printing surface is not down, it is not rubbed by horizontal feeding and cannot be seen.

  As described above, according to this embodiment, when the distal end of the rigid frame 62 is rotated upward, the rigid frame 62 swings in the distal direction as a whole. As a result, the horizontal member W placed on the roller conveyor 10 can be scooped up by the L-shaped pedestal 70 so as to wrap around from behind.

  When the roll motor MT30 is driven to rotate the crank arm 85 to retract the connection rod 86, the first link member 74 moves the bent portion of the L-shaped plate 73 forward while moving the entire L-shaped pedestal 70. Knock backwards. Thereby, it can roll over, making the lower side corner | angular part of the horizontal member W closely_contact | adhere to the L-shaped bending part.

  In the L-shaped cradle 70, the horizontal side plate 71 having the same dimension as the width of the largest horizontal member that can be processed, and 1/2 of the material of the largest horizontal member. Since the center of gravity of the horizontal member W during the rollover operation is always in the L-shaped valley of the cradle, the balance of the center of gravity is maintained during the rollover operation. Never lose.

  By these actions, it becomes possible to increase the operation speed at the time of rollover. Further, since the rigid frame 62 is supported by suspending the middle frame and the front end (original side end) so as to be swingable, interference when the rigid frame 62 is returned to the standby state is also avoided. Is able to.

  As mentioned above, although the Example of this invention was described, this invention is not restricted to the Example mentioned above, In the range which does not deviate from the summary, it can implement in a various aspect further.

  For example, before driving the wood rollover device 1, the wood rollover device 1 may be driven after scooping up the wood on the roller type conveyor 10 by the caterpillar type conveyor 20.

  It can be used in a wood precut factory for wooden houses.
