Description

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

  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.

  In the horizontal hot press, the applicant of the present invention uses a loaded roller conveyor (carrying body) of the loader unit (carrying unit) and a hot press unit (heating pressurizing unit) for the plate materials to be processed which are arranged in a standing state at predetermined intervals. ) And a conveying roller conveyor (conveying body), and proposed that these roller conveyors be constituted by rollers with claws (projections) (see Patent Document 1). According to Patent Document 1, even if the processed plate material is bent and warped, the claw of the roller is locked to the processed plate material. Can be smoothly carried into

Japanese Patent Publication No.7-115324

  However, in Patent Document 1, when the inertial force of the processed plate material stopped on the carry-in roller conveyor is larger than the frictional force between the clawd roller and the processed plate material, the clawd roller is idle (sliding). May occur, and the board material to be processed may not be carried in smoothly.

  The object of the present invention is to smoothly carry in the plate material to be processed from the carry-in body of the carry-in section into the hot plate interval of the heating and pressurizing section, thereby preventing the occurrence of clogging and the like during the conveyance and causing the device failure. It is an object of the present invention to provide a plate material carrying-in structure for a horizontal multi-stage press apparatus that can reduce and improve the product yield.

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 pressing member for assisting the transfer by the carry-in body by pressing the end surface on the rear side in the carrying direction against the plate to be processed which is transferred to the carry body in a standing state by the carry-in body. It is characterized by that.

  In such a plate material carrying-in structure, in order to assist the transfer to the conveyance body (for example, roller conveyor) by the carry-in body (for example, the carry-in roller conveyor), the pressing for pressing the end surface on the rear side in the conveyance direction of the plate material to be processed to the front side By providing a member (for example, a pressing frame), the to-be-processed board | plate material which has stopped on the carrying-in body can be smoothly transferred to the conveyance body of the conveyance direction front side. Therefore, it is possible to smoothly carry in the processed plate material from the carry-in body of the carry-in unit into the hot plate interval of the heating and pressurizing unit, prevent occurrence of clogging in the middle of conveyance and reduce the apparatus failure, Product yield can be improved. The pressing member includes a cross-sectional shape such as a plate shape, a fence shape, a frame shape, a rod shape, and a tubular shape, a single shape across all the carry-in paths, and a shape divided in the pressing direction. Further, the pressing member can be moved along the transport direction using a fluid pressure cylinder (linear drive source) such as an air cylinder or a hydraulic cylinder.

  It is desirable for such a pressing member to be able to start pressing the processed plate material before the carry-in body starts an operation for transferring the processed plate material. The pressing force of the pressing member may be exerted on the processed plate material before the conveying force of the loaded member acts on the processed plate material stopped on the loaded body (or almost simultaneously with the conveying force). As a result, the plate material to be processed can be more smoothly transferred to the carrier by the carry-in body.

  In addition, when the pressing member releases the pressing action on the plate to be processed, it is desirable that the carry-in body continues to transfer the plate to be processed to the transport body. In this way, the driving force (consumed energy) is not wasted because the pressing force of the pressing member only needs to act on the processed plate material only at the initial stage of transfer of the processed plate material by the carry-in body. Note that the operation timing of the pressing member and the carry-in body may be precisely controlled by a timer or the like, but when the air cylinder or the like that drives the press member reaches the stroke end, the carry-in body continues to transfer the plate material to be processed. Thus, it is sufficient to set the operating time of the carry-in body.

  The pressing member can press a lower position than the central position of the height in the vertical direction on the end surface on the rear side (upstream side) in the conveying direction of the plate to be processed that is transferred to the conveying body in the standing state. As a result, the pressing member can press the plate to be processed with a relatively small pressing force, so that it is easy to prevent clogging during the conveyance of the plate to be processed regardless of the vertical height (plate width). Can do.

  Alternatively, the pressing member can press higher than the central position of the height in the vertical direction on the end surface on the rear side (upstream side) in the transport direction of the plate to be processed that is transferred to the transport body in the standing state. As a result, the pressing force of the pressing member is likely to act on the carry-in body on the front side (downstream side) of the processed plate material, so that the plate thickness is large, wide, and heavy, so that the processed plate material is clogged. The pressing force of the pressing member can be effectively applied.

  6 is a plan view of the plate material carrying-in structure according to the present invention, FIG. 7 is a front view thereof, and FIG. 8 is a left side view thereof. As shown in FIG. 6, the board | plate material carrying-in structure of this invention is mainly comprised by the loader part 200 (carrying-in part) installed in the carrying-in side of the hot press part 100 (heating-pressing part). Specifically, the plate material carry-in structure 200 includes a carry-in roller conveyor 210 (carry-in body), a pair of left and right parallel carry-in chain conveyors 202L and 202R (carry-in endless body), an introduction conveyor 205 (introduction endless body), and an auxiliary carry-in chain. A conveyor 220 (auxiliary carrying endless body) and a pressing frame 230 (pressing member) are provided. The plate material carrying-in structure 200 rises from the left and right ends of the gantry 201 (see FIG. 7) and is held by the standing frames 204L and 204R extending in the front-rear direction (see FIG. 8) and arranged in the hot press unit 100. The processed plate material W1 is carried into the roller conveyor 160 (conveyance body) described above.

  As described above, the carry-in roller conveyor 210 is configured to hold a plurality of standing plate materials W1 in the front-rear direction at a predetermined interval (hot plate 130 interval) along the conveying direction, and to deliver them to the roller conveyor 160 (see FIG. For example, five claw rollers 211 are provided. These claw rollers 211 are transported to a rectangular frame-shaped carry-in roller frame 212 (carry-in support frame) that is placed on the standing frames 204L and 204R and can be displaced in the vertical direction by an elevating mechanism (not shown). It is constructed in a form along the front-rear direction at a predetermined interval in the direction. Each claw roller 211 is synchronously rotated by a single electric motor 213 (rotation drive source) via a plurality of (for example, three) drive chains 214 (see FIG. 7).

  The pair of left and right carry-in chain conveyors 202 </ b> L and 202 </ b> R introduce the plate material W <b> 1 to the carry-in roller conveyor 210 from the front side (upstream side) in the introduction direction that intersects (for example, orthogonally) the transport direction. On the front side of each of the standing frames 204L and 204R, both ends of the drive shaft 202a that drives the carry-in chain conveyors 202L and 202R are rotatably supported, while on the rear side of each of the standing frames 204L and 204R Both ends of the driven shaft 202b following the chain conveyors 202L and 202R are rotatably supported. Each of the carry-in chain conveyors 202L and 202R is configured such that a chain is wound around a sprocket fixed to the drive shaft 202a and the driven shaft 202b, and the drive shaft 202a is connected (directly connected) to a single drive motor 202c (rotation drive source). Driven by rotation.

  Further, a plurality of (hot plates 130) for changing the posture of the plate material W1 to be processed from a lying state (for example, a horizontal state) to a standing state (for example, a vertical state) along the conveying direction between the left and right carry-in chain conveyors 202L and 202R. The same number of loader shelves 203 are erected so as to be undulated (see FIG. 8). Therefore, when the carry-in roller frame 212 (carry-in roller conveyor 210) is moved downward, the left and right carry-in chain conveyors 202L and 202R change the posture of the processed plate material W1 from the lying down state to the upright state by the loader shelf 203 as it rotates. At the same time, the lower end surface of the processed plate material W1 is supported by the support surface 203a of the loader shelf 203 (see FIG. 8). Further, when the loader shelf 203 (loading chain conveyors 202L and 202R) stops in a form that coincides with the interval between the hot plates 130 (loading path K), the processed plate materials W1 are simultaneously transferred to the roller conveyor 160 by the lifted and shifted loading roller conveyor 210. (See FIG. 7).

  The loader shelf 203 is located on the front side (downstream side; hot press unit 100 side) in the transport direction and protrudes wide and long in the radial direction, and on the rear side (upstream side) in the transport direction. It includes a sub guide plate 203c that protrudes narrowly and short in the radial direction, and a connecting plate 203d that is arranged along the transport direction and connects both guide plates 203b and 203c. Further, the sub guide plate 203c and the connecting plate 203d are connected by a guide frame 203e bent in an L shape, and the side of the guide frame 203e along the introduction direction is located near the extension line of the auxiliary carry-in chain conveyor 220. Is arranged.

  The introduction conveyor 205 is provided with a plurality of (for example, four) flat belt conveyors that are parallel to each other in order to introduce the processing target plate material W1 from the front side to the loader rack 203 (the carry-in chain conveyors 202L and 202R). Have. On the front side of each of the standing frames 204L and 204R, both end sides of the drive shaft 205a for driving each introduction conveyor 205 are rotatably supported, while on the rear side of each of the standing frames 204L and 204R, each introduction conveyor Both ends of a driven shaft 205b following 205 are rotatably supported. Each introduction conveyor 205 is driven to rotate by a flat belt wound around a pulley fixed to the drive shaft 205a and the driven shaft 205b, and the drive shaft 205a is connected (directly connected) to a single drive motor 205c (rotation drive source). Is done.

  The auxiliary carry-in chain conveyor 220 is arranged between the left and right carry-in chain conveyors 202L and 202R in parallel and offset (biased) toward the carry-chain conveyor 202L on the rear side (left side; upstream side) in the transport direction. Yes. Therefore, the auxiliary carry-in chain conveyor 220 supports the lower end surface of the plate material W1 that is inclined to the left and right with respect to the introduction direction when the posture is changed from the lying down state to the standing state by the carry-in chain conveyors 202L and 202R. (See FIG. 7).

  The auxiliary carry-in chain conveyor 220 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 211. Thus, the plate material W1 can be smoothly inherited from the carry-in chain conveyors 202L and 202R and the auxiliary carry-chain conveyor 220 to the claw roller 211, and the inclination of the plate material W1 when the posture is changed or the carry-in path K is loaded. Can be prevented.

  The auxiliary carry-in chain conveyor 220 hangs a chain on a sprocket fixed to the drive shaft 202a (common drive shaft) and the driven shaft 202b of the carry-in chain conveyors 202L and 202R, and is coaxial by a single drive motor 202c (load-in drive source). 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 in FIG. 6 or FIG. 7, the pressing frame 230 is arranged by extending, for example, a square pipe so as to have a width in the front-rear direction across all the plate materials W <b> 1 (loading path K). . The pressing frame 230 presses the end surface on the rear side in the transport direction toward the processing plate material W <b> 1 transferred to the roller conveyor 160 in a standing state by the carry-in roller conveyor 210, so that the initial stage in the carry-in roller conveyor 210 is pressed. It has a function to assist (complement) transport delay.

  Specifically, the moving air cylinder 231 (linear drive source) of the pressing frame 230 is fixedly disposed on the standing frame 204L located on the rear side (upstream side) in the transport direction. Then, when the rod 231a of the moving air cylinder 231 extends, the pressing frame 230 presses the processing target plate material W1 on the carry-in roller conveyor 210 from the rear side in the transport direction to the front side. At this time, as shown in FIG. 7, the moving air cylinder 231 (rod 231a) presses the lower end of the center position of the height in the vertical direction on the end surface on the rear side in the transport direction of the processed plate material W1. The frame 230 can press the processed plate material W1 with a relatively small pressing force.

  Further, the pressing frame 230 starts pressing the processed plate material W1 before the carry-in roller conveyor 210 starts an operation for transferring the processed plate material W1. Further, when the rod 231a of the moving air cylinder 231 extends to the stroke end and the pressing frame 230 releases the pressing action on the plate material W1, the carry-in roller conveyor 210 moves the plate material W1 on the roller conveyor 160 to the plate material W1. Continue the transfer.

  Therefore, regardless of the vertical height (plate width) of the plate material W1 to be processed, the pressing frame 230 can be used to transfer the plate material W1 that is stopped on the carry-in roller conveyor 210 to the front side in the conveyance direction. By pushing toward, clogging at the initial stage of conveyance can be easily prevented. In addition, since the pressing force of the pressing frame 230 only needs to be applied to the processed plate material W1 only at the initial stage of the transfer of the processed plate material W1 by the carry-in roller conveyor 210, the driving force (consumed energy) of the moving air cylinder 231 is increased. There is no waste.

  The operation of the plate material carry-in structure 200 shown in FIGS. 6 to 8 will be described. As shown in FIG. 8, when the carry-in roller frame 212 (carry-in roller conveyor 210) is displaced upward, the transport surface 210a of the carry-in roller conveyor 210 is maintained at the same height as the transport surface 160a of the roller conveyor 160 (FIG. 7). reference). At this time, the entire conveyance surface 210a of the carry-in roller conveyor 210 is positioned higher than the locus of the support surface 203a 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).

  Then, the carry-in roller conveyor 210 moves before starting the operation (rotation) for transferring the plate materials W1 to be processed aligned in the standing state at intervals of the hot plate 130 (carry-in path K) to the roller conveyor 160. The rod 231a of the air cylinder 231 starts to extend. As a result, when the pressing frame 230 presses the processed plate material W1 in the stopped state from the rear side in the transport direction to the front side, and the processed plate material W1 starts to move in the transport direction, the carry-in roller conveyor 210 operates. Start. Eventually, the rod 231a of the moving air cylinder 231 extends to the stroke end, and the pressing frame 230 does not press the processed plate material W1, but the carry-in roller conveyor 210 operates until the processed plate material W1 is transferred to the roller conveyor 160. Continue.

  In this manner, the processing target plate material W1 can be smoothly carried into the gap between the hot plates 130 (the carry-in path K) of the hot press unit 100 from the carry-in roller conveyor 210 of the loader unit 200. Occurrence of clogging and the like can be prevented, failure of the horizontal multi-stage press apparatus 1 can be reduced, and product yield can be improved.

  Note that the pressing frame 230 may press higher than the central position of the height in the up-down direction on the end surface on the rear side in the transport direction of the processing target plate material W1 transferred to the roller conveyor 160 in the standing state. In this case, the pressing force of the pressing frame 230 is likely to act on the carry-in roller conveyor 210 on the front side in the transport direction of the plate material W1. That is, since it becomes easy to bite into the claw roller 211, the pressing force of the pressing frame 230 can be effectively exerted against clogging of the processed plate material W1, which has a large plate thickness, a wide width, and a large weight.
