Description

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

  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, the applicant of the present application in such a horizontal hot press, a stopper for stopping at a predetermined stop position when carrying a plurality of plate materials into a pressing position on the hot plate (based on the ram position of the cylinder) ( Proposed to provide a stop member (see Patent Document 1)

JP 60-118526 A

  According to Patent Literature 1, it is possible to stop a plurality of plate materials aligned at a predetermined pressing position at the time of carry-in simply by aligning the stopper with the pressing position on the hot plate. Difficult to produce uneven thickness on finished plate material. However, the plate material to be treated before heating and pressurization is different in each plate material or even in a single plate material even if the moisture content is taken, for example, bending (warping), twisting (twisting), etc. Not like that. When such plate materials are carried in all at once by a conveying body such as a roller conveyor straddling the carry-in path, the plate material does not reach the stopper even after a predetermined time and is likely to stay on the way. Thus, if the board to be processed is not loaded properly (stop position unevenness), the entire apparatus must be stopped to remove the remaining board by human power or move to a predetermined stop position. There is a risk that the efficiency of the sheet will be reduced, or the processed plate material may have uneven thickness.

  The problem of the present invention is that the plate material of the horizontal multi-stage press apparatus that can correct the insufficient loading state of the plate material to be processed and efficiently execute the heating and pressurizing process, and can prevent the occurrence of defective products such as uneven thickness of the processed plate material. It is to provide a positioning structure.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the plate material positioning structure of the horizontal multi-stage press device of the present invention is:
A plurality of plates to be processed held in an upright state are respectively carried between a plurality of hot plates by a carrier disposed across individual loading paths formed along the surface to be pressed, and each substrate to be processed It is a plate material positioning structure of a horizontal multi-stage press device that heats and presses the processed plate materials all at once with the plurality of hot plates, with the thickness direction of the plate material as the pressing direction,
Plate material detecting means that is disposed on the front side or the rear side in the conveying direction of the carry-in path of the plate material to be processed and detects that each plate material to be processed has been carried to a predetermined stop position;
When it is detected by the plate material detection means that an insufficient carry-in state that is not carried into the stop position in any of the plate materials to be processed is activated before the heating and pressurization by the hot plate, And an auxiliary conveyance body that re-introduces the to-be-processed plate material in a state of insufficient conveyance along the corresponding conveyance path to the stop position.

  In this way, the plate material detecting means is arranged in the carry-in path of the plate material to be processed, and when the occurrence of an insufficient loading state is detected by the plate material detecting means, the auxiliary conveyance body is operated to return the plate material to be processed to a predetermined stop position. Carry in. Therefore, a plurality of plate materials to be processed can be aligned at a predetermined stop position (pressing position) and heated and pressed (press-molded) all at once by a plurality of hot plates that sandwich the plate materials to be processed. As a result, the insufficient loading state of the plate material to be processed is corrected, and the heating and pressing process can be executed efficiently. In addition, unevenness of the plate thickness is less likely to occur in the processed plate after heating and pressing, and the product yield can be improved (the occurrence of defective products can be reduced).

In such a plate material positioning structure,
(1) A system in which plate material detection means is provided in a state where all the carry-in paths are seen, and an auxiliary transport body is provided across all the carry-in paths;
(2) A system in which plate material detection means is provided in a state where all the carry-in paths are seen, and an auxiliary transport body is provided for each carry-in path;
(3) A system in which plate material detection means is provided for each carry-in path and an auxiliary transport body is provided across all the carry-in paths;
(4) A method of providing a plate material detecting means and an auxiliary transport body for each carry-in path;
Any of these may be adopted. In the cases (1) and (2), a transmissive non-contact sensor such as a transmissive photoelectric sensor or a transmissive ultrasonic sensor is desirable as the plate material detecting means. In the case of (3) and (4), as a plate material detecting means, a proximity switch such as a capacitance type, a reflection type non-contact sensor (a reflection type photoelectric sensor, a reflection type ultrasonic sensor, etc.) or a contact sensor ( Limit switches, micro switches, etc.) are desirable. However, regardless of (1) to (4), the plate material detection means may be provided on either the front side (leading side) or the rear side (tail side) in the carrying direction of the carry-in path.

The auxiliary conveying body of the plate material positioning structure has an operating state in which the processed plate material is reintroduced to the stop position by pushing the rear end in the conveying direction of the processed plate material that is not fully loaded into the carry-in path, and the plate material detecting means It is possible to switch (displace) to a non-operating state that retreats outside the carry-in path on the rear side in the transport direction and allows passage of the plate material to be processed in the next process,
The auxiliary transport body is kept in an inactive state when the processed plate material is carried in by the transport body, and shifts to an operating state (displacement) when the plate material detecting means detects the processed plate material that is insufficiently loaded. It is desirable to return (displace) to a non-operating state by the time of carrying in a to-be-processed board | plate material.

  In this way, the auxiliary transport body is switched (displaced) between an operating state in which the plate material to be processed is reintroduced and a non-operating state in which it is retracted out of the carry-in path. Therefore, when supplying the plate material to be processed between the heat plates (carry-in path) by the transport body, the auxiliary transport body only needs to be retracted outside the carry-in path and switched to the non-operating state so as not to hinder the carry-in. . On the other hand, once there is a shortage of loading in the plate to be processed, the auxiliary transporter is in an operating state, and the plate to be processed in which the shortage of loading has occurred can be reloaded to a predetermined stop position. The pressurization process can be executed with high efficiency without stagnation.

The stop position includes a receiving state that enters the carry-in path to receive the front end of the processed board material in the conveyance direction, and a processed board that has retreated outside the carry-in path and has finished performing the heating and pressurization by the hot plate. A stop member that can be switched (displaced) to a retracted state that allows passage is disposed,
The stopping member holds the receiving state when the processed plate material is carried in by the conveying body, maintains the receiving state when the auxiliary conveying member is operated, and is retracted until the processed plate material is carried out by the conveying body. It is desirable to shift to (displace) and return (displace) to a receiving state by the time of carrying in the board material to be processed in the next process.

  In this manner, the stop member is switched (displaced) between the receiving state when the processed plate material is carried in and the retreat state where the stopping member is retreated outside the carrying-in path. Therefore, when supplying the plate material to be processed between the heat plates (carrying-in path) by the transport body or re-loading it by the auxiliary transport body, the stop member enters the transport-in path and sets the front end in the transport direction of the plate material to be processed. Since it can be received, each plate material to be processed can be stopped at a fixed position (stop position), and the heating and pressurizing process for the plate material to be processed can be executed with high efficiency without stagnation. On the other hand, when the processed plate material is carried out by the carrier, the stop member can be retracted outside the carry-in path prior to the carry-out process, so that the carry-out process can be performed without delay by using the carry-in path as it is as the carry-out path. . As a result, the next process can be smoothly started.

  By the way, when viewed from the pressing direction, the plate material detection means is arranged in the carry-in path of the plate material to be processed, in front of the rear end edge in the conveyance direction of the hot plate held in the suspended state, and the plate material detection means is insufficiently loaded. When the processed plate material in the state is detected, the auxiliary conveyance body can re-load the processed plate material in the insufficiently loaded state from the rear side in the conveyance direction to the stop position. Re-loading from the rear-side stay position to the front-side stop position even when re-loading along a transport path where there is a transport stop (for example, a roller conveyor that has stopped rotating for transport) Since the direction of is coincident with the transport direction, the situation in which the stop transport body acts as a resistance or a brake on the re-loading plate material (for example, the state where the feeding protrusion on the roller surface bites into the re-loading plate material) is relatively It is hard to occur. Therefore, there is little risk of damaging the re-loading plate material (processed plate material) by re-loading using the auxiliary transporter, and the heating and pressurizing process can be started after all the processed plate materials are aligned at the pressing position.

  Specifically, when viewed from the pressing direction, the plate material detection means is provided between the conveyance surface of the processed plate material formed by the conveyance body and the lower end surface (lower edge) of the hot plate positioned higher than that. It can be arranged in the carry-in path. Thus, if the plate material detection means is arranged higher than the conveying surface and lower than the lower end surface of the hot plate, regardless of the type of the plate material detection means (for example, contact type or non-contact type) (regardless of the type) The presence or absence can be reliably detected without hindering the carrying-in.

  In addition, the auxiliary conveyance body is located at a position rearward of the plate material detection unit before the operation, and moves until it passes the plate material detection unit (passes) and moves to a front position in the conveyance direction along with the operation. As a result, the processed plate material whose presence has been detected by the plate material detection means (detection of insufficient loading state) is pushed from the rear by the auxiliary carrier until the plate material detection means detects the absence (detection of the completion of loading). By carrying in, all the plate materials to be processed can be aligned at a predetermined pressing position.

  On the other hand, when viewed from the pressing direction, the plate material detection means is disposed in the carry-in path of the plate material to be processed behind the rear end edge in the conveyance direction of the hot plate held in a suspended state, and the plate material detection means is in an insufficiently loaded state. When the plate material to be processed is detected, the auxiliary conveyance body can re-load the plate material to be processed, which is insufficiently loaded, from the rear side in the conveyance direction to the stop position. Therefore, there is little risk of damaging the re-loading plate material (processed plate material) by re-loading using the auxiliary transporter, and the heating and pressurizing process can be started after all the processed plate materials are aligned at the pressing position. Moreover, since the plate material detection means is disposed behind the rear edge in the conveyance direction of the hot plate, when the carry-in is stopped due to a significant shortage of loading state that part of the plate material to be processed protrudes from the pressing surface of the hot plate However, it is possible to detect the occurrence of the insufficient loading state by the plate material detection means, and operate the auxiliary conveyance body to re-load the processed plate material in the insufficient loading state.

  Also in this case, the auxiliary transport body is in the rear position in the transport direction with respect to the plate material detection means before the operation, and moves to the front position in the transport direction after passing (passing) the plate material detection means with the operation. To do. Similarly to the above, the plate material to be processed whose presence has been detected by the plate material detection means (detection of an insufficient carry-in state) is pushed from the rear by the auxiliary conveyance body until the plate material detection means detects the absence (detection of the carry-in completion state). By re-loading, all the plate materials to be processed can be aligned at a predetermined pressing position.

  In any case, the auxiliary conveyance body is arranged across all the carry-in paths so that a plurality of processed board materials in a shortage of carry-in state can be simultaneously re-loaded to the stop position. In some cases, it is configured by a non-contact sensor that detects the presence or absence of a plate material to be processed that is not loaded properly. In such a case, the plate material detection means detects the entire carry-in path, and the auxiliary transport body conveys across the entire carry-in path, so that when the plate material detection means detects the presence of a plate material to be processed in an insufficiently loaded state, Immediately, the auxiliary carrier can be actuated to simultaneously carry in all of the board materials that are under-loaded. Accordingly, it is possible to efficiently complete the re-introduction of the plate material to be processed which is in a shortage of the in-carried state, and to quickly move to the next process (heat pressurizing process), thereby shortening the cycle time. The auxiliary transport body 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 form across all the carry-in paths, a form divided in the pressing direction, and the like.

In the plate material positioning structure of the horizontal multi-stage press apparatus as described above,
In the vicinity of the auxiliary transport body and on the front side in the transport direction, when the transported plate material is carried in by the transport body, the lower surface of the processed plate material is supported from below, so that the processed plate material spans all the carry-in paths. A processing target plate material supporting means having a supporting surface;
The processed plate material support means conveys the processed plate material whose processed plate material support surface is formed by the conveyance body regardless of whether the auxiliary conveyance body is in an activated state or inactive state (regardless of that). In addition to being positioned on the extension of the surface, it is also possible to move (displace) in the direction of pushing the plate to be processed together with the auxiliary transport body in the operating state of the auxiliary transport body.

  As described above, the auxiliary transfer body that can be switched between the operating state and the non-operating state is accompanied by a change in position (especially, retreating out of the carrying-in path in the non-operating state), which may hinder the loading of the plate material to be processed. In the vicinity of the auxiliary conveyance body, there is provided a processing plate material support means for supporting the processing plate material from below. Therefore, by providing the processed plate material support means, the holding posture (supported state from the lower side) of the loaded processed plate material becomes unstable and tilts in the movement area of the auxiliary transport body (with respect to the transport direction). Inclining). At that time, regardless of whether the auxiliary transport body is in an activated state or inactive state (that is, regardless of whether or not the auxiliary transport body is retracted out of the carry-in path), the processing target plate material support surface is transported. Since it is located on the extension of the surface and is disposed across all the carry-in paths, the plate material to be processed can be held stably at all times. In addition, a to-be-processed board | plate material support means is comprised, for example with a cylindrical roller, and it can convey (carry in), driving and rotating independently, supporting a to-be-processed board | plate material from lower side.

Similarly, in the plate material positioning structure of the horizontal multi-stage press device,
While the stop member is arranged across all the carry-in paths so that the stop position of each plate to be processed can be defined and received simultaneously in the receiving state,
An adjusting means for moving and adjusting the disposition position of the stop member in the transport direction according to the size of the pressed surface of the processed plate material carried in by the transport body;
In the vicinity of the stop member and on the front side in the transport direction, when the processed plate material is carried out by the transport body, the processed plate material is supported across all the carry-in paths in order to support the lower end surface of the processed plate material from below. A treated plate material support means having a surface,
The processed plate material support means is a conveyance surface of the processed plate material on which the processed plate material support surface is formed by the conveyance body regardless of whether the stop member is in a receiving state or in a retracted state It is also possible to move (displace) in the transport direction together with the stop member in a state where the stop member is positioned by the adjusting means.

  As described above, the stop member that can be switched between the receiving state and the retracted state is accompanied by a change in position (especially, retracting out of the loading path in the retracted state) so as not to hinder the unloading of the processed plate material. In addition, a processed plate material support means for supporting the processed plate material from below is provided in the vicinity of the stop member. Therefore, by providing the processed plate material support means, the holding posture (supported state from the lower side) of the processed plate material to be carried out is inclined in the movement region of the stop member (inclined with respect to the conveyance direction). To prevent). At that time, regardless of whether the stop member is in the receiving state or in the retracted state (that is, regardless of whether or not the stop member is retracted outside the carry-in path), the processed plate material support surface is Since it is located on the extension and disposed across all the carry-in paths, the processed plate material can be held stably at all times. The processed plate material support means is constituted by, for example, a cylindrical roller, and can be transported (carried out) while being driven and rotated independently to support the processed plate material from below.

The press plates 140F and 140B are disposed to face the respective heat plates 130 located on both sides in the front-rear direction of the hot plate group, and the upper sides of the press plates 140F and 140B are connected to the moving rollers 105L and 105R to move forward and backward. Suspend freely in the direction. Further, the pressing plates 140F and 140B are connected to the rams 151L and 151R of the hydraulic cylinders 150L and 150R provided on the fixed frames 103F and 103B, and can be reciprocated in the front-rear direction by the rams 151L and 151R. Note that the pressing plates 140F and 140B in FIG. 3 reciprocate in the front-rear direction with respect to the fixed frames 103F and 103B.

  The hot plates 130 in the hot plate group, and the hot plates 130 at both ends and the press plates 140F and 140B are connected to each other by a space restricting tool 131 in order to maintain a predetermined front-rear space when the press is released.

  In addition, a plurality of claw rollers 161 that carry in, support, and carry out the processing target plate material W1 in an upright direction are provided below the hot plate 130 in the suspended hot plate group. A roller conveyor 160 is disposed, and the upper surface of the plurality of claw-equipped rollers 161 serves as a conveyance surface.

  Next, FIG. 6 is a front view of the plate material positioning structure, FIG. 7 is an enlarged front view of the main part, and FIG. 8 is an enlarged plan view of the main part. As shown in FIG. 6, in the hot press unit 100 (heating and pressing unit; press structure), a stopper 170 (stop member; disposed on the front side (leading side; right side) of the carry-in path K of the plate material W1 to be processed. A plate material positioning structure), a transmission type photoelectric sensor 10 (transmission type non-contact sensor; plate material detection means; plate material positioning structure) disposed on the rear side (tail side; left side) of the carry-in path K of the processed plate material W1; A moving plate 180 (auxiliary transport body; plate material positioning structure) disposed on the rear side of the carry-in path K of the plate material W1 to be processed is provided.

  The stopper 170 is disposed at the loading stop position of each processed plate material W1, the photoelectric sensor 10 detects that each processed plate material W1 has been loaded to the stop position (stopper 170 position), and the movable plate 180 is in an insufficiently loaded state. The plate material W1 to be processed is reintroduced to the stop position (stopper 170 position) along the corresponding carry-in path K. That is, the carry-in stop position of the processing target plate material W1 where the stopper 170 is arranged represents the pressing position (heating and pressing position) of the processing target plate material W1 by the hot plate 130.

  As shown in an enlarged view in FIG. 7, the photoelectric sensor 10 is disposed in the carry-in path K of the processed plate material W <b> 1 at the front lower side than the rear end edge in the transport direction of the hot plate 130. Specifically, the photoelectric sensor 10 carries in between the conveyance surface 160a of the processed plate material W1 formed by the roller conveyor 160 and the lower end surface 130a (lower end edge) of the hot plate 130 positioned higher than that. It is arranged in the path K. This photoelectric sensor 10 detects the presence or absence of the to-be-processed board | plate material W1 of the under-loading state which is not carried in to a stop position (stopper 170 position) in the state which sees all the carrying-in paths K in the front-back direction (pressing direction) ( (See FIG. 8).

  Then, when the photoelectric sensor 10 detects the board material W1 that is in an insufficiently loaded state in any of the carry-in paths K, the movable plate 180 is unprocessed in the loading board W1 before the heating plate 130 performs the heating and pressurization. Is controlled from the rear side (left side) in the transport direction to carry in again to the stop position. The photoelectric sensors 10 are installed at a plurality of locations (for example, 4 locations) along the delivery path K in the left-right direction (conveyance direction) so that the stop position of the processing target plate material W1 is near the center of the hot plate 130. In addition, the photoelectric sensor 10 used for the carry-in control is selected and set according to the size of the pressed surface of the processed plate material W1.

  As shown in FIG. 7, the movable plate 180 can be switched (displaced) between an operating state Q1 (operating position) and a non-operating state Q2 (non-operating position). In the operating state Q1, the moving plate 180 enters the carry-in path K and pushes the rear end (left end) in the conveyance direction of the plate material W1 that is not fully loaded, thereby stopping the plate material W1 at the stop position (stopper 170 position). Re-load until. On the other hand, in the non-operating state Q2, the moving plate 180 retreats out of the carry-in path K and allows the plate material W1 to be processed in the next process to pass. Therefore, the moving plate 180 maintains the non-operation state Q2 when the processed plate material W1 is carried in by the roller conveyor 160, and shifts to the activated state Q1 when the photoelectric sensor 10 detects the processed plate material W1 in an insufficiently loaded state. (Displacement), and return (displace) to the non-operational state Q2 by the time of carrying in the plate material W1 to be processed in the next process.

  In other words, the moving plate 180 in the non-operating state Q2 is positioned lower than the transport surface 160a of the roller conveyor 160 on the rear side in the transport direction (left side; for example, the position corresponding to the rear edge of the heat plate 130 in the transport direction). is doing. In addition, the moving plate 180 in the operating state Q1 has a photoelectric path along the carry-in path K between the conveying surface 160a of the roller conveyor 160 and the lower end surface 130a (lower end edge) of the hot plate 130 positioned higher than that. From the rear side (left side) of the sensor 10, the light beam of the photoelectric sensor 10 crosses and moves to the front side (right side) of the photoelectric sensor 10. The movable plate 180 is disposed across all the carry-in paths K so that a plurality of the plate materials W1 in the carry-in insufficient state can be simultaneously re-loaded to the stop position (see FIG. 8).

  Switching between the non-operating state Q2 and the operating state Q1 of the moving plate 180 is performed by a moving plate elevating cylinder 181 (linear drive source; see FIG. 9) and a moving plate moving cylinder 182 (linear drive source; see FIG. 8). Done.

  The support structure of the moving plate 180 will be further described. As shown in FIGS. 7 and 8, a pair (four in total) of columns 123 are installed on the front and rear and on the left and right below the roller conveyor 160. Among these, the left and right lower horizontal beams 102L and 102R are bridged between the front and rear columns 123, and a plurality of (for example, two) moving plates are provided between the lower left horizontal beam 102L and the moving plate 180 at a predetermined interval in the front-rear direction. The moving cylinder 182 is bridged.

  Specifically, as shown in FIG. 7, the support frame 185 (support body; see FIG. 9) that is below the moving plate 180 and supports the moving plate 180 is supported in the left-right direction (conveying direction). The distal end of the rod 182a of the moving plate moving cylinder 182 disposed at is fixed. Further, as shown in FIG. 8, the support frame 185 is penetrated in the left-right direction between the horizontal beam 187 that is fixed to the left lower beam 102 </ b> L and extends rearward (left side) in the conveyance direction. A plurality of (for example, four) movement guides 186 (guide bodies) are fixed. Accordingly, the moving plate moving cylinder 182 is guided by the moving guide 186 by the expansion and contraction of the rod 182a and slides the support frame 185 left and right. Each claw roller 161 is supported by a pair of front and rear fixed beams 163 spanned between the left and right lower horizontal beams 102L and 102R, and a roller conveyor motor 162 (rotation drive source) is also provided on the left lower horizontal beam 102L. (Or fixed beam 163).

  As shown in FIG. 9, the lower end of the moving plate elevating cylinder 181 disposed so as to vertically penetrate the supporting frame 185 is fixed to the support frame 185, and the upper end of the rod 181 a of the moving plate elevating cylinder 181 is fixed. Is fixed to the horizontal portion 180a of the moving plate 180 formed in a right-angle shape (for example, L-shape). The lower end of a lifting guide 188 (guide body) arranged in a form penetrating in parallel with the moving plate lifting cylinder 181 is fixed to the support frame 185, and the upper end of the lifting guide 188 is the horizontal portion 180 a of the moving plate 180. And protrudes in parallel with the vertical portion 180b. Accordingly, the moving plate lifting / lowering cylinder 181 is guided by the lifting guide 188 by the expansion and contraction of the rod 181a to slide the moving plate 180 up and down.

  As shown in FIG. 8, the moving plate 180 is provided with a carry-in side auxiliary roller 183 (processed plate material support means), and is independently rotated by a carry-in side auxiliary roller motor 184 (rotation drive source). The carry-in side auxiliary roller 183 is disposed on the front side (right side) in the conveyance direction in the vicinity of the moving plate 180, and supports the lower end surface of the processed plate material W1 from below when the processed plate material W1 is loaded by the roller conveyor 160. Therefore, it has the to-be-processed board | plate material support surface 183a (refer FIG. 7) ranging over all the carrying-in paths K. FIG.

  As shown in FIG. 7, since the carry-in side auxiliary roller 183 is attached to the support frame 185, the processed plate material support surface 183a is related to whether the movable plate 180 is in the operating state Q1 or the non-operating state Q2. It is always located on the extension (same height) of the conveyance surface 160a of the roller conveyor 160. Then, the carry-in side auxiliary roller 183 pushes the processed plate material W1 in a state of insufficient carry-in together with the moving plate 180 in the operating state Q1 of the moving plate 180 accompanying the retraction of the rod 182a of the moving plate moving cylinder 182 (forward in the carrying direction). Side). Accordingly, the carry-in side auxiliary roller 183 moves (displaces) by the moving plate moving cylinder 182, but does not move up and down (displaced) by the moving plate elevating cylinder 181.

  In FIG. 7, the stopper 170 can be switched (displaced) between a receiving state P1 (stop position) and a retracted state P2 (retracted position). In the receiving state P1, the stopper 170 enters the carry-in path K and receives the front end (right end) of the processed plate material W1. On the other hand, in the retracted state P2, the stopper 170 allows passage of the processed plate material W2 that has been retracted out of the carry-in path K and the heating and pressurization by the hot plate 130 has been completed. Therefore, the stopper 170 holds the receiving state P1 when the processed plate material W1 is carried in by the roller conveyor 160, and maintains the receiving state P1 when the moving plate 180 is operated (operating state Q1). By the time 160, the processed plate material W2 is transferred (displaced) to the retracted state P2 by the time when the processed plate material W2 is unloaded, and is returned (displaced) to the receiving state P1 by the time the next processed plate material W1 is loaded.

  That is, the stopper 170 is always disposed at the front end (right end) of the loading stop position of the processed plate material W1. The stopper 170 in the received state P1 is positioned higher than the transport surface 160a of the roller conveyor 160 and receives the front end (right end) of the loaded plate material W1. Further, the stopper 170 in the lowered and retracted state P <b> 2 is positioned lower than the conveying surface 160 a of the roller conveyor 160. And the stopper 170 is arrange | positioned ranging over all the carrying-in paths K so that the stop position of each to-be-processed board | plate material W1 may be prescribed | regulated and received simultaneously in the receiving state P1 (refer FIG. 8).

  Switching between the retracted state P2 and the receiving state P1 of the stopper 170 is performed by a stopper lifting cylinder 171 (linear drive source; see FIG. 9). In addition, the stopper 170 is set to a stop position below the hot plate 130 in the horizontal direction by a stopper moving cylinder 172 (linear drive source; adjusting means; see FIG. 8) according to the size of the pressed surface of the plate material W1. The movement can be adjusted in the (conveyance direction).

  The support structure for the stopper 170 will be further described. As shown in FIGS. 7 and 8, a pair (four in total) of columns 123 are installed on the front and rear and on the left and right below the roller conveyor 160. Among these, the left and right lower horizontal beams 102L and 102R are bridged between the front and rear columns 123, and a plurality of (for example, two) stoppers are moved between the right lower horizontal beam 102R and the stopper 170 at a predetermined interval in the front-rear direction. The cylinder 172 is bridged.

  Specifically, as shown in FIG. 7, the support frame 175 (support body; see FIG. 9) below the stopper 170 and supporting the stopper 170 is arranged in the left-right direction (conveyance direction). The tip of the rod 172a of the stopper moving cylinder 172 is fixed. Further, as shown in FIG. 8, the horizontal frame 177 is fixed to the right lower horizontal beam 102 </ b> R and extends forward (right side) in the conveyance direction, and the lower horizontal beam 102 </ b> R penetrates the support frame 175 in the left-right direction. A plurality of (for example, four) movement guides 176 (guide bodies) are fixed. Thus, the stopper moving cylinder 172 is guided by the movement guide 176 by the expansion and contraction of the rod 172a and slides the support frame 175 left and right.

  As shown in FIG. 9, the lower end of the stopper lifting cylinder 171 arranged in a form penetrating the support frame 175 in the vertical direction is fixed to the support frame 175, and the upper end of the rod 171 a of the stopper lifting cylinder 171 is It is fixed to a horizontal portion 170a of a stopper 170 formed in a right angle (for example, L shape). Further, the lower end of a lifting guide 178 (guide body) disposed in a form penetrating in parallel with the stopper lifting cylinder 171 is fixed to the support frame 175, and the upper end of the lifting guide 178 passes through the horizontal portion 170 a of the stopper 170. Thus, it protrudes in parallel with the vertical portion 170b. Accordingly, the stopper elevating cylinder 171 is guided by the elevating guide 178 by the expansion and contraction of the rod 171a to slide the stopper 170 up and down.

  As shown in FIG. 8, the stopper 170 is provided with a carry-out side auxiliary roller 173 (processed plate material support means), and is independently rotated by a carry-out side auxiliary roller motor 174 (rotation drive source). The carry-out side auxiliary roller 173 is disposed on the front side (right side) in the transport direction in the vicinity of the stopper 170, and supports the lower end surface of the processed plate material W2 from below when the processed plate material W2 is transferred by the roller conveyor 160. Furthermore, it has the processed board material support surface 173a (refer FIG. 7) over all the carrying-in paths K.

  As shown in FIG. 7, since the carry-out side auxiliary roller 173 is attached to the support frame 175, the processed plate material support surface 173a has no relation to whether the stopper 170 is in the receiving state P1 or the retracted state P2. It is always located on the extension (same height) of the conveying surface 160a of the roller conveyor 160. The carry-out side auxiliary roller 173 moves (displaces) together with the stopper 170 in the left-right direction (the front side or the rear side in the conveying direction) in a state in which the stopper 170 is disposed in accordance with the expansion and contraction of the rod 172a of the stopper moving cylinder 172. . Accordingly, the carry-out side auxiliary roller 173 moves (displaces) by the stopper moving cylinder 172, but does not move up and down (displaced) by the stopper lifting cylinder 171.

  FIG. 10 is a block diagram schematically showing an electrical configuration of plate material positioning control. A control board 20 that is a plate material positioning control unit of the hot press unit 100 includes a CPU 21 (auxiliary transport body control means) that is an arithmetic device, a ROM 23 that is a read-only storage device, and a readable / writable main storage device that serves as a work area. The RAM 22 used and an input / output interface (I / O) 24 are mainly configured. These devices are connected via a bus 25 so as to be able to transmit and receive each other. The ROM 23 stores and stores in advance a control program 23a for executing the plate material positioning process, a setting table 23b for initially setting the size of the pressed surface of the processed plate material W1, and the like.

As shown in FIG. 10, the following signals are input to the control board 20 from each unit of the hot press unit 100 via the input / output interface 24.

Stopper moving cylinder 172: The rod 172a is expanded and contracted, and the position of the stopper 170 (loading start position of the processed plate material W1) is moved together with the discharge-side auxiliary roller 173 in accordance with the size of the pressed surface of the processed plate material W1. Control output signal to adjust;
A moving plate lifting / lowering cylinder 181: a control output signal for expanding and contracting the rod 181a to move the moving plate 180 up and down between the operating state Q1 and the non-operating state Q2;
-Moving plate moving cylinder 182: The rod 182a is expanded and contracted, and the stop position of the moving plate 180 (the loading end position of the processed plate material W1) is set in accordance with the size of the pressed surface of the processed plate material W1. And a control output signal for moving and displacing the moving plate 180 together with the carry-in side auxiliary roller 183 between the operating state Q1 and the non-operating state Q2.

Unloading side auxiliary roller motor 174: Control output signal for rotating / stopping the unloading side auxiliary roller 173;
A carry-in auxiliary roller motor 184: a control output signal for rotating / stopping the carry-in auxiliary roller 183.

  Next, the plate material positioning control in the hot press unit 100 will be described with reference to the flowchart of FIG. 11 and the operation explanatory diagram of FIG. The flowchart of FIG. 11 corresponds to the control program 23a stored in the ROM 23 of FIG.

  First, in S1, the size of the pressed surface of the processed plate material W1 is manually input by the setting switch 20a. Based on the input contents, initial setting is performed with reference to the setting table 23b (FIG. 10) of the ROM 23. Specifically, in S2, the photoelectric sensor 10 to be used is selected according to the size of the processed plate material W1, the stopper moving cylinder 172 moves and adjusts the arrangement positions of the stopper 170 and the carry-out side auxiliary roller 173, and moves The stop position of the moving plate 180 and the carry-in side auxiliary roller 183 is moved and adjusted by the plate moving cylinder 182 (see FIG. 7). Next, in S3, the stopper 170 is lifted and displaced to the receiving state P1 by the stopper lifting cylinder 171. At the same time, in S4, the moving plate 180 is moved to the non-actuated state Q2 by the moving plate lifting cylinder 181 and the moving plate moving cylinder 182. (See FIG. 12A).

  Further, in step S5, the roller conveyor 160 is driven and rotated by the roller conveyor motor 162 for a predetermined time, and in step S6, the loading-side auxiliary roller 183 is driven and rotated for a predetermined time by the loading-side auxiliary roller motor 184. Is carried into the carry-in path K (see FIG. 12A). In S <b> 7, it is confirmed whether the photoelectric sensor 10 detects the processed board material W <b> 1 ′ (refer to FIG. 12A) that is in an insufficiently loaded state in any of the loading paths K. If the photoelectric sensor 10 has detected a shortage state (YES in S7), the moving plate lifting cylinder 181 and the moving plate moving cylinder 182 hold the moving plate 180 in the operating state Q1 for a predetermined time in S8, At the same time, the loading-side auxiliary roller 183 is driven and rotated for a predetermined time by the loading-side auxiliary roller motor 184 in S9, and the board material W1 ′ to be processed is loaded again along the loading path K (FIG. 12B). reference).

  Thereafter, in S10, it is confirmed whether or not the photoelectric sensor 10 detects the completion of the loading of all the processed plate materials W1. If the photoelectric sensor 10 detects completion of loading (YES in S10), the hot plate 130 is closed by the hot press cylinders 150L and 150R in S11, and the processed plate material W1 is hot pressed (heated) for a predetermined time in S12. Pressure), and the hot plate 130 is opened in S13. In S14, the stopper 170 is moved downwardly to the retracted state P2 by the stopper lifting / lowering cylinder 171 (see FIG. 12C). Subsequently, in S15, the roller conveyor 160 is driven and rotated by the roller conveyor motor 162 for a predetermined time, and at the same time, the unloading side auxiliary roller 173 is driven and rotated by the unloading side auxiliary roller motor 174 in S16. W2 is carried out from the carry-in path K (see FIG. 12C). Then, it returns to S3 and starts carrying in the to-be-processed board | plate material W1 of the next process.

  If no carry-in shortage state has occurred in all carry-in paths K (NO in S7), hot-pressing after S11 is executed without performing re-loading with the moving plate 180. Further, if the carry-in insufficient state has not been resolved even after re-carrying by the moving plate 180 (NO in S10), an alarm “under carrying-in insufficient state” is issued in S17 and the control is stopped.

  As described above, the transmission type photoelectric sensor 10 is arranged in the carry-in path K of the plate material W1 to be processed, and when the photoelectric sensor 10 detects the occurrence of an insufficient carry-in state, the movable plate 180 is operated to operate the plate material to be processed. Reload W1 to a predetermined stop position (stopper 170 position). In this way, after the plurality of plate materials W1 are aligned at a predetermined stop position (pressing position), the hot plate molding can be performed simultaneously by the plurality of hot plates 130 sandwiching the plate materials W1 to be processed. Therefore, the insufficient loading state of the plate material W1 to be processed is quickly corrected, and the hot press process can be executed efficiently. Further, unevenness of the plate thickness is less likely to occur in the processed plate material W2 after the hot pressing, and the product yield is improved (the occurrence of defective products is reduced). In addition, by using the transmissive photoelectric sensor 10, it is possible to detect the occurrence of an insufficient loading state in a narrow space in the loading path K without hindering the flow of the processing target plate material W1.

  Since the driven plate-type auxiliary roller 183 is attached to the movable plate 180, the plate material W1 to be processed can be loaded and re-loaded smoothly. Furthermore, since the driven carry-out auxiliary roller 173 is attached to the stopper 170, the processed plate material W2 can be carried out smoothly. Since the roller conveyor 160, the stopper 170, the carry-out side auxiliary roller 173, the moving plate 180, and the carry-in side auxiliary roller 183 are all disposed across all the carry-in paths K, the configuration is simplified and the cycle time is shortened. be able to.

(Modification)
FIG. 13 shows an example of changing the arrangement of the photoelectric sensor and the moving plate. In FIG. 13, the photoelectric sensor 10 is arranged in the carry-in path K of the plate material W <b> 1 behind the rear edge (left side) of the heat plate 130 in the conveyance direction (left end). Therefore, the moving plate 180 in the non-operating state Q2 is positioned lower than the conveying surface 160a of the roller conveyor 160 on the rear side (left side) in the conveying direction further than the photoelectric sensor 10. Also in this example, when the photoelectric sensor 10 detects the processed board material W1 ′ that is in an insufficiently loaded state, the movable plate 180 moves the processed board material W1 ′ that is in an insufficiently loaded state from the rear side (left side) in the transport direction to the stop position (stopper). 170 position).

  In this manner, by disposing the photoelectric sensor 10 behind the rear edge in the conveyance direction of the hot plate 130, even the processed plate material W 1 ′ that has become large and short enough to protrude from the hot plate 130 is moved by the moving plate 180. It can be re-loaded to the stop position. According to this example, it is possible to avoid the occurrence of molding defects (such as uneven thickness of the plate) in the processed plate W2 due to the protrusion from the hot plate 130, thereby further improving the product yield.
