Description

  The present invention relates to a plate material carry-in structure and a plate material carry-out structure of a horizontal multi-stage press apparatus that heats and presses a plate to be processed, and also relates to a horizontal multi-stage press apparatus using them.

  In a multi-stage press device (hot press) that heats and presses a plate material (processed plate material) such as plywood, decorative board, fiber board, particle board, veneer veneer, etc., to a predetermined plate thickness, a plurality of pieces held in an upright state A horizontal type is known in which a plurality of plate materials are carried between heated plates arranged and heated and pressed. This horizontal method (horizontal hot press) is a plate material and hot plate compared to the vertical method (vertical hot press) in which plate materials and hot plates held in the horizontal direction are alternately stacked in the vertical direction and heated and pressed. It has the advantage that molding unevenness (uneven thickness) due to its own weight is less likely to occur.

  Then, in such a horizontal hot press, the applicant of the present application continuously changes the posture of a large number of plate materials to be processed from a stacked horizontal state (falling state) to a vertical state (standing state) arranged at predetermined intervals ( A loader shelf) was proposed (see Patent Document 1). According to Patent Document 1, it is possible to change the posture of a large number of processed plate materials in a short time, and to carry processed plate materials aligned in an upright state simultaneously between hot plates of a hot press unit (heating and pressing unit). This makes it possible to improve work efficiency.

Japanese Patent Publication No. 3-77761

  However, in patent document 1, there exists a possibility that it cannot respond to the enlargement of the processing number of the board material currently processed. For example, in the past, models that heated and pressed several tens of sheets at a time were common, but recently, there are more than a hundred models, and the weight that is transported at a time is increasing due to the increase in length. is there. In connection with this, since a large amount of processed plate materials are carried into the hot press section, the carry-in section may become enormous and equipment costs and energy consumption may increase. The same applies to the carry-out section for carrying out the processed plate material from the hot press section.

  An object of the present invention is to cope with an increase in the number of processed sheets and to suppress an increase in equipment cost and energy consumption, and to use a plate material carrying structure and a plate material carrying structure of a horizontal multi-stage press apparatus having high versatility, and using them. An object of the present invention is to provide a horizontal multi-stage press apparatus.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the plate material carrying structure of the horizontal multi-stage press device of the present invention is
A plurality of processed plate materials whose postures are changed from a lying state to a standing state on the carry-in side are respectively carried between a plurality of heat plates parallel to the conveyance direction by a conveyance body arranged across the individual conveyance paths of the heating and pressing unit. The plate material carrying structure of a horizontal multi-stage press device that heats and presses the thickness direction of each plate material to be treated simultaneously with the plurality of hot plates as a pressing direction,
A carry-in body having a conveyance surface that can be maintained at the same height as the conveyance surface of the conveyance body in order to hold the plate to be treated in a standing state along the conveyance direction at a predetermined interval and to transfer the processed plate material to the conveyance body; ,
A plurality of loader shelves for raising and lowering the position of the processed plate material from the lying down state to the standing state along the transfer direction are introduced into the carry-in body from the introduction direction intersecting the conveying direction. A pair of carry-in endless bodies erected,
A loading body rotation mechanism for adjusting the rotation of the loading body around a rotation axis disposed along the conveyance direction;
The carrying surface of the carry-in body supports the lower end surface of the plate material to be processed in an upright state by rotating the carry-in body around the rotation axis by the carry-in body turning mechanism. A predetermined positional relationship is maintained between the trajectory of the support surface formed on the endless loader shelf and the transport surface of the transport body.

  In such a plate material carry-in structure, the structure is simplified by including a carry-in body rotation mechanism (for example, a carry-in hydraulic cylinder) for adjusting the carry-in body (for example, a carry-in roller conveyor) around the rotation axis. Therefore, versatility can be improved by suppressing an increase in equipment cost and energy consumption. For example, when the entire frame on which the loading body is placed is adjusted up and down, it is necessary to provide four loading hydraulic cylinders at the four corners of the loading frame. By reducing (dispersing) the load, it becomes possible to reduce the number (for example, halve) or downsize the carry-in hydraulic cylinder.

  Moreover, by adjusting the rotation of the loading body rotation mechanism, the conveyance surface of the loading body, the trajectory of the support surface formed on the loader shelf of the loading endless body (for example, loading chain conveyor), and the conveyance body (for example, roller conveyor) The relative positional relationship with the transport surface can be maintained (maintained). Therefore, the processed plate material whose posture has been changed from the lying down state to the standing state by the loader shelf of the loaded endless body can be inherited to the loaded body and further transferred to the conveying body, and the processed plate material (work) to the hot press section Supply can be performed smoothly without delay. In addition to the hydraulic cylinder, a fluid pressure cylinder (linear drive source) such as an air cylinder or a fluid pressure motor (rotary drive source) such as a hydraulic motor can be used as a drive source for the carry-in body rotation mechanism.

  Then, the rotation axis of the loading body rotating mechanism is arranged on the introduction end side of the plate material to be processed in the loading body, and the loading body can be adjusted up and down on the introduction start side of the plate material to be processed by the rotation adjustment by the loading body rotation mechanism. It is desirable that In this way, by arranging the rotation axis of the carry-in turning mechanism on the introduction end side of the plate material to be processed in the carry-in body, the near side (introduction end side; downstream in the introduction direction) of the carry-in body is the front side. (Introduction start side) can be adjusted up and down. Therefore, if the front side (introduction start side; upstream side in the introduction direction) of the carry-in body is lowered for introduction (supply) of the plate-to-be-treated material into the carry-in part such as a carry-in endless body, It can be carried in smoothly.

  Specifically, when the introduction start side of the carry-in body is moved downward by rotation adjustment by the carry-in body turning mechanism, the carrying surface of the carry-in body is maintained at a lower position than the carrying surface of the carry body, and the carry-in endless It may be located at least partially lower than the trajectory of the support surface formed on the body loader shelf. That is, when the processed plate material is changed from the lying down state to the standing state by the loader shelf of the loaded endless body and aligned at a predetermined interval, the alignment state of the processed plate material is disturbed by the rotation adjustment by the loaded body rotating mechanism. The carry-in body can be evacuated to a position where it does not exist. Thereby, the carrying-in body and the carrying-in endless body can be arranged so as to overlap each other while avoiding mutual interference, and the plate material carrying-in structure can be simplified.

  Further, when the introduction start side of the carry-in body is lifted and displaced by the rotation adjustment by the carry-in body turning mechanism, the carrying surface of the carry-in body is maintained at the same height as the carrying surface of the carry body, The whole can be positioned higher than the trajectory of the support surface formed on the loader shelf. In other words, the processed plate material whose posture is changed from the lying down state to the standing state by the loader shelf of the carry-in endless body and aligned at a predetermined interval is transferred to the carry-in body by the rotation adjustment by the carry-in body turning mechanism, and further to the transport body. Can be transported. Thereby, the carrying-in body and the carrying-in endless body can be arranged so as to overlap each other while avoiding mutual interference, and the plate material carrying-in structure can be simplified.

On the other hand, in order to solve the above problems, the plate material carry-out structure of the horizontal multi-stage press device of the present invention is:
A plurality of processed plate materials whose postures are changed from a lying state to a standing state on the carry-in side are respectively carried between a plurality of heat plates parallel to the conveyance direction by a conveyance body arranged across the individual conveyance paths of the heating and pressing unit. The heating plate is heated and pressed all at once by the plurality of hot plates with the thickness direction of each plate to be processed as the pressing direction, and then the plurality of processed plate members carried along the carry-in path are raised on the carry-out side. It is a plate material carrying structure of a horizontal multi-stage press device that changes its posture from a state to a lying state,
An unloading body having a transport surface that can be maintained at the same height as the transport surface of the transport body in order to hold the processed plate material in a standing state along the transport direction at a predetermined interval and transfer the processed plate material from the transport body; ,
A plurality of unloader shelves for undulating each of the unloaded shelves for deriving the processed plate material from the unloading body in a deriving direction intersecting the conveying direction and changing the posture of the processed plate material from a standing state to a lying state along the deriving direction. A pair of unfinished unfinished bodies,
An unloading body rotation mechanism for rotating and adjusting the unloading body around a rotation axis disposed along the transport direction;
By adjusting the unloading body around the rotation axis by the unloading body rotating mechanism, the carrying surface of the unloading body supports the lower end face of the processed plate material in the standing state. A predetermined positional relationship is maintained between the trajectory of the support surface formed on the endless unloader shelf and the transport surface of the transport body.

  In such a plate material carry-out structure, the structure is simplified by including a carry-out body rotation mechanism (for example, a carry-out hydraulic cylinder) for rotating and adjusting the carry-out body (eg, carry-out roller conveyor) around the rotation axis. Therefore, versatility can be improved by suppressing an increase in equipment cost and energy consumption. For example, when the entire carry-out frame on which the carry-out body is placed is adjusted up and down, it is necessary to provide four carry-out hydraulic cylinders at the four corners of the carry-out frame. By reducing (dispersing) the load to be carried out, it is possible to reduce the number (for example, halve) or downsize the carry-out hydraulic cylinder.

  Moreover, by adjusting the rotation of the unloading body rotating mechanism, the conveying surface of the unloading body, the locus of the support surface formed on the loader shelf of the unloading endless body (for example, unloading chain conveyor), and the conveying body (for example, roller conveyor) The relative positional relationship with the transport surface can be maintained (maintained). Therefore, the processed plate material transported from the transport body can be transferred to the transport body and transferred to the transport endless body, and the posture can be changed from the standing state to the lying state by the unloader shelf. The plate material (work) can be picked up smoothly without delay. In addition to the hydraulic cylinder, a fluid pressure cylinder (linear drive source) such as an air cylinder or a fluid pressure motor (rotary drive source) such as a hydraulic motor can be used as a drive source for the unloading body rotation mechanism.

  The rotation axis of the unloading body rotating mechanism is arranged on the discharge start side of the processed plate material in the unloading body, and the unloading body can be adjusted up and down by the rotation adjustment by the unloading body rotating mechanism. It is desirable that In this way, by arranging the rotation axis of the unloading body rotating mechanism on the discharge start side of the processed plate material in the unloading body, the front side with respect to the back side (leading start side; upstream side in the discharging direction) of the unloading body (Driving end side; downstream side in the derivation direction) can be adjusted up and down. Therefore, if the front side (leading end side) of the unloading body is moved downward in order to lead out (take out) the processed plate material to the unloading part such as the unloading endless body, the processed plate material can be smoothly unloaded and led out. The

  Specifically, when the unloading end side of the unloading body is moved downward by the rotation adjustment by the unloading body rotating mechanism, the conveying surface of the unloading body is maintained at a lower position than the conveying surface of the conveying body, and the unloading endless It can be located at least partially lower than the trajectory of the support surface formed on the body unloader shelf. In other words, when the processed plate material is changed from the standing state to the lying down state by the unloader shelf of the unloaded endless body, the alignment state of the processed plate material is not disturbed by the rotation adjustment by the unloading body rotation mechanism. The carry-out body can be retracted. Accordingly, the carry-out body and the carry-out endless body can be arranged so as to overlap each other while avoiding mutual interference, and the plate material carry-out structure can be simplified.

  Also, when the unloading end side of the unloading body is lifted and displaced by the rotation adjustment by the unloading body rotating mechanism, the conveying surface of the unloading body is maintained at the same height as the conveying surface of the conveying body, and the unloaded endless body The whole can be positioned higher than the trajectory of the support surface formed on the unloader shelf. That is, the processed plate material transferred from the transport body can be transferred to the carry-out body, and can be derived by changing the posture from the standing state to the lying-down state by the unloader shelf of the carry-out endless body. Accordingly, the carry-out body and the carry-out endless body can be arranged so as to overlap each other while avoiding mutual interference, and the plate material carry-out structure can be simplified.

Next, in order to solve the above problems, the horizontal multi-stage press apparatus of the present invention is:
While providing the plate material carry-in structure as described above on the carry-in side,
Equipped with the above plate material carry-out structure on the carry-out side,
On the carry-in side, the pair of loadless endless loader shelves change the posture from the lying down state to the upright state, and a plurality of processed plate materials that support the lower end surface with the support surface of the loader shelves, the loader and the transporter Are carried in between a plurality of heat plates parallel to the conveying direction, and heated and pressed by the plurality of heat plates all at once with the thickness direction of each processed plate material as a pressing direction, and then carried in by the conveying body and the unloading body. At the unloading side, a plurality of processed plate materials unloaded along the path are supported at the lower end surface by the unloader shelf support surface of the pair of unloaded endless bodies, and the posture is changed from the standing state to the lying down state by the unloader shelf. It is characterized by doing.

  Thus, by adjusting the rotation of the loading body (unloading body) around the rotation axis, it is possible to suppress an increase in equipment costs and energy consumption, so the number of processed plate materials (processed plate materials) is processed. Therefore, it is possible to realize a horizontal multi-stage press apparatus with high versatility.

Driven, the transmission structure is simplified. Note that the link speed of the auxiliary carry-in chain is smaller than the link pitch of the carry-in chain (for example, about half), and the moving speed of the auxiliary carry-in chain conveyor 220 and the carry-in chain conveyors 202L and 202R (that is, the introduction speed of the plate material W1 to be processed). Are set equal.

  As shown mainly in FIGS. 8 and 9, the conveyance surface 210 a connecting the upper edges of the claw rollers 211 of the carry-in roller conveyor 210 is adjusted by the carry-in body turning mechanism 215 to adjust the carry-in chain conveyor 202 </ b> L, The mutual positional relationship is changed with respect to the trajectory of the support surface 203a of the loader shelf 203R of 202R and the conveyance surface 160a connecting the upper edges of the claw rollers 161 of the roller conveyor 160. The outline is as follows.

  That is, when the rods 217a of the carry-in side hydraulic cylinders 217L and 217R are contracted and the introduction start side of the carry-in roller frame 212 (the carry-in roller conveyor 210) is lowered, the transfer surface 210a of the carry-in roller conveyor 210 is It is positioned lower than the transfer surface 160a. At this time, as shown in FIG. 9B, the transport surface 210 a of the carry-in roller conveyor 210 is lowered with respect to the locus of the support surface 203 a of the loader shelf 203, leaving a part of the introduction end side (back side). positioned. Accordingly, as the loading chain conveyors 202L and 202R rotate, the loader shelf 203 changes the posture of the plate material W1 from the lying down state to the upright state, and the support surface 203a of the loader shelf 203 supports the lower end surface of the plate material W1. Then, it can be introduced sequentially to the rear side (back side).

  On the other hand, when the rods 217a of the carry-in side hydraulic cylinders 217L and 217R are extended and the introduction start side of the carry-in roller frame 212 (the carry-in roller conveyor 210) is displaced upward, the carrying surface 210a of the carry-in roller conveyor 210 is carried by the roller conveyor 160. It is maintained at the same height as the surface 160a (see FIG. 7). At this time, as shown in FIG. 9A, the entire conveyance surface 210 a of the carry-in roller conveyor 210 is positioned higher than the trajectory of the support surface 203 a of the loader shelf 203. Therefore, with the rotation of the carry-in roller conveyor 210, the lower end surface of the processed plate material W1 is supported by the carrying surface 210a, and can be carried all at once into the carry-in path K (roller conveyor 160).

  The operation of the plate material carry-in structure 200 shown in FIGS. 6 to 9 will be described. First, when the rods 217a of the carry-in side hydraulic cylinders 217L and 217R are contracted and the introduction start side of the carry-in roller frame 212 (load-in roller conveyor 210) is lowered, the carry-in roller conveyor 210 as shown in FIG. 9B. Most of the transfer surface 210 a is positioned lower than the locus of the support surface 203 a of the loader shelf 203. Next, the drive motors 205c and 202c are driven to rotate the introduction conveyor 205, the carry-in chain conveyors 202L and 202R, and the auxiliary carry-in chain conveyor 220. When the board material W1 to be processed is introduced from the front-side introduction conveyor 205, the posture of the board material W1 is changed from the lying state to the standing state along the conveying direction by the loader shelves 203 of the carry-in conveyors 202L and 202R. The support surface 203a of the shelf 203 supports the lower end surface of the plate to be processed W1 and sequentially introduces it to the rear side. At this time, the auxiliary carry-in chain conveyor 220 supports the lower end surface of the processing target plate material W1 tilted to the left and right with respect to the introduction direction when the posture is changed. When a predetermined number (for example, 100 sheets) of the plate materials W1 to be processed are accommodated between the loader shelves 203 in a form that matches the interval between the hot plates 130 (the carry-in path K), the drive motors 205c and 202c are stopped.

  Thereafter, when the rods 217a of the carry-in side hydraulic cylinders 217L and 217R are extended and the introduction start side of the carry-in roller frame 212 (the carry-in roller conveyor 210) is moved upward, the carrying surface 210a of the carry-in roller conveyor 210 is carried by the roller conveyor 160. It is maintained at the same height as the surface 160a (see FIG. 7). Next, the electric motor 213 is driven to rotate the carry-in roller conveyor 210. At this time, as shown in FIG. 9A, the entire conveying surface 210a of the carry-in roller conveyor 210 is positioned higher than the trajectory of the support surface 203a of the loader shelf 203. The lower end surface of the plate material W1 to be processed is supported and carried into the carry-in path K (roller conveyor 160) all at once (see FIG. 7), and the drive of the electric motor 213 is stopped.

  By the way, as shown in FIG. 6, by providing the loading side hydraulic cylinders 217L and 217R for adjusting the rotation of the loading roller conveyor 210 around the loading side rotation axis O1, the structure can be simplified, and the equipment cost and Increase in energy consumption can be suppressed and versatility can be improved. In other words, such a rotation type reduces (disperses) the load to be supported, and there is no need to provide hydraulic cylinders at the four corners of the carry-in roller frame 212 as in the prior art, so the load-side hydraulic cylinders 217L and 217R The number can be reduced by half.

  Moreover, by adjusting the rotation of the loading body rotation mechanism 215, the conveyance surface 210 a of the loading roller conveyor 210, the trajectory of the support surface 203 a formed on the loader shelf 203 of the loading chain conveyors 202 </ b> L and 202 </ b> R, and the conveyance of the roller conveyor 160. The relative positional relationship with the surface 160a can be maintained (maintained). Therefore, the processed plate material W1 whose posture has been changed from the lying down state to the standing state by the loader shelves 203 of the carry-in chain conveyors 202L and 202R can be transferred to the carry-in roller conveyor 210 and further passed to the roller conveyor 160. It is possible to smoothly supply the plate material W1 to be processed without any delay.

Are arranged along the conveying direction. Further, on the derivation end side (front side; derivation direction downstream side) of the processed plate material W2, a pair of left and right unloading side hydraulic cylinders 317L and 317R (unloading side linear drive source) are connected to the unloading roller frame 312 and the standing frame 304L, It is installed between 304R and the lifting / lowering adjustment is performed on the lead-out end side of the carry-out roller conveyor 310 by expansion and contraction of the rod 317a (see FIGS. 12 and 13). Each claw roller 311 is synchronously rotated by a single electric motor 313 (rotation drive source) via a plurality of (for example, three) drive chains 314 (see FIG. 11).

  The pair of left and right carry-out chain conveyors 302L and 302R lead the processed plate material W2 to the carry-out roller conveyor 310 from the rear side (upstream side) in the lead-out direction that intersects (for example, orthogonal) with the transport direction.

The same number of unloader shelves 303 are erected in a undulating manner (see FIG. 12). Therefore, when the carry-out roller frame 312 (carry-out roller conveyor 310) is displaced upward, the unloader shelf 303 (carry-out chain conveyors 302L and 302R) is stopped in a form that matches the interval between the hot plates 130 (carry-in path K). The processed plate material W2 can be unloaded from the roller conveyor 160 to the unloading roller conveyor 310 all at once. Further, when the carry-out roller conveyor 310 is displaced downward, the left and right carry-out chain conveyors 302L and 302R change the posture of the processed plate material W2 from the standing state to the lying state by the unloader shelf 303 along with the rotation, and the unloader shelf 303 The lower end surface of the processed plate material W2 is supported by the support surface 303a (see FIG. 12).

  The unloader shelf 303 is located on the rear side (upstream side; hot press unit 100 side) in the transport direction and protrudes wide and long in the radial direction, and on the front side (downstream side) in the transport direction. It includes a sub guide plate 303c that protrudes narrowly and short in the radial direction, and a connecting plate 303d that is arranged along the transport direction and connects both guide plates 303b and 303c. Further, the main guide plate 303b and the connection plate 303d are connected by a guide frame 303e bent in an L shape, and the side of the guide frame 303e along the lead-out direction is positioned near the extension line of the auxiliary carry-out chain conveyor 320.

  The auxiliary carry-out chain conveyor 320 is arranged in parallel between the left and right carry-out chain conveyors 302L and 302R and offset (biased) toward the carry-out chain conveyor 302L on the rear side (left side; upstream side) in the transport direction. Yes. Therefore, the auxiliary carry-out chain conveyor 320 supports the lower end surface of the processed plate material W2 tilted to the left and right with respect to the lead-out direction when changing the posture from the standing state to the lying down state by the carry-out chain conveyors 302L and 302R. (See FIG. 11).

  The auxiliary carry-out chain conveyor 320 is provided between two rollers on the rear end side (left end side; upstream end side) in the transport direction among the five claw rollers 311. Accordingly, the processed plate material W2 can be smoothly transferred from the claw roller 311 to the carry-out chain conveyors 302L and 302R and the auxiliary carry-out chain conveyor 320, and the processed plate material W2 is inclined when being taken out from the carry-in path K or when the posture is changed. Can be prevented.

  The auxiliary carry-out chain conveyor 320 hangs a chain on a sprocket fixed to the drive shaft 302a (common drive shaft) and the driven shaft 302b of the carry-out chain conveyors 302L and 302R, and is coaxial by a single drive motor 302c (carry-out drive source). Driven, the transmission structure is simplified. The link speed of the auxiliary carry-out chain is smaller than the link pitch of the carry-out chain (for example, about half), and the moving speed of the auxiliary carry-out chain conveyor 320 and the carry-out chain conveyors 302L and 302R (that is, the derivation speed of the processed plate material W2). Are set equal.

The outline is as follows.

  That is, when the rod 317a of the carry-out side hydraulic cylinders 317L and 317R is extended and the lead-out end side of the carry-out roller frame 312 (the carry-out roller conveyor 310) is displaced upward, the carrying surface 310a of the carry-out roller conveyor 310 is carried by the roller conveyor 160. It is maintained at the same height as the surface 160a (see FIG. 11). At this time, as shown in FIG. 13A, the entire conveyance surface 310 a of the carry-out roller conveyor 310 is located at a higher level than the locus of the support surface 303 a of the unloader shelf 303. Therefore, with the rotation of the carry-out roller conveyor 310, the lower end surface of the processed plate material W2 is supported by the carrying surface 310a and can be carried out from the carry-in path K (roller conveyor 160) all at once.

  On the other hand, when the rod 317a of the carry-out side hydraulic cylinders 317L and 317R is contracted and the lead-out end side of the carry-out roller frame 312 (the carry-out roller conveyor 310) is moved downward, the transfer surface 310a of the carry-out roller conveyor 310 is It is positioned lower than the transfer surface 160a. At this time, as shown in FIG. 13B, the transport surface 310 a of the carry-out roller conveyor 310 is lowered with respect to the trajectory of the support surface 303 a of the unloader shelf 303, leaving a part of the derivation start side (back side). positioned. Accordingly, the unloader shelf 303 changes the posture of the processed plate material W2 from the standing state to the lying down state as the carry-out chain conveyors 302L and 302R rotate, and the support surface 303a of the unloader shelf 303 supports the lower end surface of the processed plate material W2. Then, it can be sequentially derived to the front side (front side).

  The operation of the plate material carry-out structure 300 shown in FIGS. 10 to 13 will be described. First, when the rod 317a of the carry-out side hydraulic cylinders 317L and 317R is extended and the lead-out end side of the carry-out roller frame 312 (the carry-out roller conveyor 310) is lifted and displaced, as shown in FIG. The transport surface 310a is maintained at the same height as the transport surface 160a of the roller conveyor 160 (see FIG. 11). Next, the electric motor 313 is driven to rotate the carry-out roller conveyor 310. At this time, as shown in FIG. 13A, the entire conveying surface 310a of the carry-out roller conveyor 310 is positioned higher than the locus of the support surface 303a of the unloader shelf 303. 160), the lower end surfaces of all the processed plate materials W2 that are unloaded all at once are supported by the conveying surface 310a (see FIG. 11), and the electric motor 313 is stopped.

  Thereafter, when the rod 317a of the carry-out side hydraulic cylinders 317L and 317R is contracted and the discharge end side of the carry-out roller frame 312 (the carry-out roller conveyor 310) is lowered and displaced, as shown in FIG. Most of the transfer surface 310 a is positioned lower than the locus of the support surface 303 a of the unloader shelf 303. Next, the drive motors 305c and 302c are driven to rotate the lead-out conveyor 305, the carry-out chain conveyors 302L and 302R, and the auxiliary carry-out chain conveyor 320. The unloader shelves 303 of the carry-out chain conveyors 302L and 302R change the posture of the processed plate material W2 from the standing state along the conveying direction to the lying down state, and the support surface 303a of the unloader shelf 303 supports the lower end surface of the processed plate material W2. Derived sequentially forward. At this time, the auxiliary carry-out chain conveyor 320 supports the lower end surface of the processed plate material W2 tilted to the left and right with respect to the lead-out direction when the posture is changed. The processed plate material W2 in the lying state is led out from the lead-out conveyor 305 on the front side, and the drive motors 305c and 302c are stopped.

  By the way, as shown in FIG. 10, by providing unloading-side hydraulic cylinders 317L and 317R for rotating the unloading roller conveyor 310 around the unloading-side rotation axis O2, the structure can be simplified, and the equipment cost and Increase in energy consumption can be suppressed and versatility can be improved. That is, the load to be supported is reduced (distributed) by using such a rotation type, and there is no need to provide hydraulic cylinders at the four corners of the carry-out roller frame 310 as in the prior art, so the carry-out side hydraulic cylinders 317L and 317R The number can be reduced by half.

  Moreover, by adjusting the rotation of the unloading body rotation mechanism 315, the conveyance surface 310a of the unloading roller conveyor 310, the locus of the support surface 303a formed on the unloader shelves 303 of the unloading chain conveyors 302L and 302R, and the conveyance of the roller conveyor 160 are carried out. The relative positional relationship with the surface 160a can be maintained (maintained). Accordingly, the processed plate material W2 unloaded from the roller conveyor 160 is transferred to the loading roller conveyor 210, and further transferred to the unloading chain conveyors 302L and 302R, and the posture can be changed from the standing state to the lying down state by the unloader shelf 303.
