Description

  The present invention relates to a hot plate holding 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.

  In this horizontal hot press, the applicant of the present application holds each hot plate in a suspended form by a bracket (hot plate holding member) with a moving roller (moving member) and releases the pressure after the hot press process. In some cases, it has been proposed that the mutual spacing between the hot plates is regulated by a spacing regulator (spacing holding member) (see Patent Document 1). According to Patent Document 1, since the hot plate is held in a suspended shape, for example, twisting of the hot plate is less likely to occur during opening and closing as compared with a case where the hot plate is supported vertically. In addition, since the mutual spacing of the hot plates when releasing pressure can be kept constant, even if the hot plate spacing is relatively narrow, loading and unloading the plate material to be processed into the loading path formed between the hot plates It is possible to smoothly carry out the processed plate material from the path. In this way, the hot plate and thus the entire horizontal hot press apparatus is reduced in thickness and size.

Japanese Patent Publication No. 3-67482

  However, in patent document 1, the space | interval control tool which hold | maintains the hot plate | board space | interval at the time of pressurization release is being fixed to the bracket which attaches a moving roller and hold | maintains a hot plate | board in a suspended form. For this reason, when the bracket holds the hot plate near the end in the conveying direction (outside), the distance between the moving rollers (tread; wheel ring) is relatively large, and therefore due to thermal expansion of the hot plate. The elongation (absolute value) of the tread becomes large, and there is a risk of hindering the smooth movement of the moving roller on the rail. On the other hand, when the bracket holds the hot plate near the center in the conveyance direction (inner side), the spacing regulator is also located near the center in the conveyance direction, so that the heat plate is heated by thermal expansion such as bending (warping). When the deformation occurs, the hot plate intervals (pitch) at the time of releasing the pressure are likely to be uneven, and there is a risk that the carrying-in of the plate material to be processed and the carrying-out of the processed plate material may be hindered. In addition, when exchanging the worn / deformed moving roller, it may be necessary to attach and detach the interval restricting tool to / from the bracket.

  The problem of the present invention is that the hot plate holding member and the gap holding member are rationally arranged with respect to the hot plate, thereby suppressing a problem associated with the thermal expansion of the hot plate and facilitating replacement of the moving member. The object is to provide a hot plate holding structure of a multistage press apparatus.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the hot plate holding 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 each carried between a plurality of suspended hot plates by means of a carrier arranged across individual carry-in paths formed along the surface to be pressed. A heat plate holding structure of a horizontal multi-stage press device that heats and presses the processed plate materials simultaneously with the plurality of hot plates, with the thickness direction of the processed plate materials as a pressing direction,
A plurality of parallel rails fixedly arranged along the pressing direction;
In order to support the moving member that moves along the rail, and to hold the hot plate in a suspended manner on both sides in the conveying direction, a hot plate holding member that is attached in pairs for each hot plate;
On both outer sides in the conveying direction of the pair of hot plate holding members, there are provided gap holding members that are attached in pairs for each hot plate in order to regulate the mutual distance between adjacent hot plates when the hot plate is pressurized and released. ,
The spacing member and the hot plate holding member are separately fixed to the hot plate, and the mounting span of the pair of spacing members is different from the mounting span of the pair of hot plate holding members for each hot plate. Is also configured to be large.

  By providing such a hot plate holding structure, the gap holding member (for example, the gap regulating tool) is positioned relatively closer to the outer end (outside) of the hot plate in the conveyance direction, so that the hot plate bends due to thermal expansion ( Even when thermal deformation such as warping occurs, the hot plate interval (pitch) at the time of releasing the pressure is made uniform, and it is possible to smoothly carry in the plate material to be processed and carry out the processed plate material after the heat and pressure treatment. In addition, since the moving member (for example, the moving roller) can be disposed relatively closer to the center (inner side) in the conveyance direction of the hot plate, the extension amount of the distance between the moving members (tread; (Absolute value) becomes smaller and can move smoothly with respect to the rail (rail) over a long period of time. Furthermore, since the gap holding member and the hot plate holding member (for example, a bracket) are separately fixed to the hot plate, when replacing a worn / deformed moving member, it is possible to hold the hot plate without removing the gap holding member. What is necessary is just to attach and detach (exchange) a member.

  As described above, the occurrence of problems associated with the thermal expansion of the hot plate is suppressed, the replacement of the moving member is facilitated, and the working accuracy of the hot plate holding structure can be increased.

In addition, the rails are fixedly arranged on each side of the conveyance direction,
The moving member is attached to the hot plate via the hot plate holding member, and is configured as a (single) rotating wheel that rotates and moves any one of the rails on both sides in the transport direction,
When viewed from the standing direction of the hot plate, the rotating wheels attached to the hot plate holding member are alternately displaced along the pressing direction with respect to a pair of rails arranged on one side in the conveying direction (in a staggered pattern) ) Can be placed.

  In this way, by placing the rotating wheels alternately with respect to the pair of rails (that is, in a staggered pattern), the distance between the rotating wheels (tread; the wheel range) can be further shortened. Therefore, the rotating wheel can move more smoothly with respect to the rail (rail).

Therefore, in order to solve the above problem, the hot plate holding 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 each carried between a plurality of suspended hot plates by means of a carrier arranged across individual carry-in paths formed along the surface to be pressed. A heat plate holding structure of a horizontal multi-stage press device that heats and presses the processed plate materials simultaneously with the plurality of hot plates, with the thickness direction of the processed plate materials as a pressing direction,

In order to support a rotating wheel that moves along one of the rails on both sides in the transport direction and to hold the hot plate in a suspended form on both sides in the transport direction, A hot plate holding member attached one by one;
On both outer sides in the conveying direction of the pair of hot plate holding members, there are provided gap holding members that are attached in pairs for each hot plate in order to regulate the mutual distance between adjacent hot plates when the hot plate is pressurized and released. ,
The spacing member and the hot plate holding member are separately fixed to the hot plate, respectively, and when viewed from the standing direction of the hot plate, the rotating wheel is disposed on a pair of rails arranged on one side in the transport direction. On the other hand, the mounting position of the hot plate holding member supporting the rotating wheel to the hot plate is changed by being placed in a form shifted alternately along the pressing direction,
Regardless of the change of the mounting position of the hot plate holding member, the mounting span of the pair of gap holding members is configured to be larger than the mounting span of the pair of hot plate holding members for each hot plate. And

  Thus, as the rotating wheels are mounted alternately in a staggered manner with respect to the pair of rails (in a staggered pattern), the attachment spans of the pair of hot plate holding members are in the hot plate array direction (pressing If the long span L1 and the short span L2 are alternately arranged along the direction), a shorter span state can be realized. Moreover, even in this case, since the attachment span of the pair of spacing members is configured to be larger than the attachment span of the pair of hot plate holding members, the occurrence of problems associated with the thermal expansion of the hot plate is suppressed, The replacement of the rotating wheel is facilitated, and the working accuracy of the hot plate holding structure can be increased.

  At this time, if a plurality of pairs of the spacing members are provided on both outer sides in the conveyance direction across the rails and straddle between the adjacent hot plates and are sequentially offset (shifted) in the conveyance direction, heating is performed. The interval between the hot plates can be reduced during pressurization, and can be easily applied to a thin plate to be processed.

Therefore, in order to solve the above problem, the hot plate holding 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 each carried between a plurality of suspended hot plates by means of a carrier arranged across individual carry-in paths formed along the surface to be pressed.

By arranging a plurality of pairs while sequentially turning in the direction, the mounting position of the spacing member to the hot plate is changed,
Regardless of the change in the mounting position of the spacing member, the mounting span of the pair of spacing members is configured to be larger than the mounting span of the pair of heating plates for each hot plate. To do.

  As a result, the distance between the hot plates can be reduced during heating and pressurization, so that the apparatus can be made more compact and compact. Moreover, even in this case, since the attachment span of the pair of spacing members is configured to be larger than the attachment span of the pair of hot plate holding members, the occurrence of problems associated with the thermal expansion of the hot plate is suppressed, The replacement of the rotating wheel is facilitated, and the working accuracy of the hot plate holding structure can be increased.

Furthermore, in order to solve the said subject, the hot plate holding structure of the horizontal type multistage press apparatus of this invention is the following.

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.

  Next, FIG. 6 is a plan view of a hot plate holding structure according to the present invention, FIG. 7 is a side view of an essential part thereof, and FIG. 8 is an explanatory view showing a mounting structure of a bracket and a moving roller. As shown in FIG. 6, the hot plate holding structure 120 of the present invention is provided with rails 104 </ b> L and 104 </ b> R along the pressing direction on the cross beams 101 </ b> L and 101 </ b> R provided on the fixed frames 103 </ b> F and 103 </ b> B. Each rail 104L, 104R includes a pair of parallel rails 104L1, 104L2 and rails 104R1, 104R2.

  The pair of rails 104L1 and 104L2 and the rails 104R1 and 104R2 include guide grooves 104a (see FIG. 8) formed in a concave groove shape, and are fixedly arranged on both sides in the transport direction. Further, the moving rollers 105L and 105R (moving members) moving along the rails 104L and 104R are respectively attached to the hot plate 130 via a pair of brackets 132 (hot plate holding members). The moving rollers 105L and 105R are configured as a single rotating wheel that rotationally moves one of the pair of rails 104L1 and 104L2; 104R1 and 104R2 on both sides in the transport direction.

  On the other hand, a pair of space | interval control tools 131 (space | interval holding member) are each attached to the hot platen 130 via a pair of connection tool 135 (intermediate member), and are separated and fixed separately from the bracket 132. The attachment of the coupler 135 is directly fixed to the upper part of the hot plate 130 with a fastening member 170 such as a bolt at different positions on both outer sides in the conveying direction with respect to the attachment position on the pair of brackets 132 (FIG. 7). FIG. 9).

  Thus, the space | interval control tool 131 and the bracket 132 are formed separately, and are each fixed to the hot platen 130.

  The bracket 132 is directly fixed by a fastening member 170 such as a bolt as shown in FIG. Further, the bracket 132 has an attachment base portion 132a for attachment to the heat plate 130, a support portion 132b is erected from the attachment base portion 132a, and the moving rollers 105L and 105R are attached to the upper portion of the support portion 132b. It has a mounting part 132c oriented in the horizontal direction.

  FIG. 6 shows two types of fixing the bracket 132 with the moving rollers 105 </ b> L and 105 </ b> R to the hot plate 130. In the first fixing mode, the mounting portions 132c of the pair of brackets 132 are arranged to face each other and fixed to the heat plate 130, and the moving rollers 105L and 105R mounted on the inner side are placed on the outer rails 104L1 and 104R2, respectively. It is a form to do. In the second fixing mode, the mounting portions 132c of the pair of brackets 132 are arranged back to back and fixed to the heat plate 130, and the moving rollers 105L and 105R attached to the outside are mounted on the inner rails 104L2 and 104R1, respectively. It is a form to put. The hot plates 130 to which the brackets 132 are fixed in such two types are arranged alternately in the pressing direction (front-rear direction) to form a hot plate group.

  By the way, when paying attention to the pair of rails 104L1 and 104L2 (or 104R1 and 104R2) arranged on one side in the transport direction, the above two types can be expressed as follows. In other words, the moving rollers 105L and 105R are placed in a staggered manner (in a state of being alternately displaced along the pressing direction) in a state where the moving rollers 105L and 105R are displaced back and forth in the transport direction in the pressing direction.

  Accordingly, the attachment spans (intervals in the conveying direction) of the pair of brackets 132 are long span L1 (first fixed form) and short span L2 (second fixed form) along the hot plate array direction (pressing direction). ) And are repeated alternately. In other words, the treads (ring distance) of the moving rollers 105L and 105R are large in the first fixed form and small in the second fixed form, and are repeated alternately along the front-rear direction. However, the attachment span L (the mutual distance in the transport direction) of the pair of spacing restriction tools 131 is set to be larger than any of the attachment spans (long span L1, short span L2) of the pair of brackets 132. .

  As shown in FIG. 9, the coupler 135 has a fixed base portion 135a for fixing to the upper portion of the heat plate 130, and a fixed engagement portion 135b is erected from the fixed base portion 135a. An attachment portion 131A on one end side of the spacing restriction tool 131 formed in a gate shape is fixed to the fixed engagement portion 135b with a bolt 170. Note that an engaging portion 131B oriented in the pressing direction is formed at the free end, which is the other end side of the space restricting tool 131, and the fixed engaging portion 135b of the connecting tool 135 engages with the space restricting tool 131 when pressure is released. It contacts (contacts) the inner surface of the part 131B.

  In addition, the engaging portion 131 </ b> B that is a free end of the space restricting tool 131 is disposed across the hot plates 130. Between the attachment portion 131A and the engagement portion 131B of the spacing restriction tool 131, the fixed engagement portion 135b of the coupling tool 135 is inserted and positioned. Therefore, when the hot plate 130 is released from pressure, the fixed engaging portion 135b of the coupling tool 135 abuts on the inner surface of the engaging portion 131B of the interval restricting tool 131, and the mutual interval between the adjacent hot plates 130 is restricted. .

  The space restricting tool 131 fixed to the heat plate 130 via the connecting tool 135 is in the transport direction with other space restricting tools 131 fixed to the adjacent heat plate 130 on both outer sides in the transport direction across the rails 104L and 104R. A plurality of pairs (for example, 6 pairs; see FIG. 6) are disposed so as to be displaced so that they do not overlap and are sequentially offset in the conveying direction. Accordingly, the interval between the hot plates 130 can be narrowed during heating and pressurization, and can be easily applied to a thin plate material W1.

  As shown in FIG. 10, the spacing restricting tool 131 is disposed between the adjacent heat plates 130 and sequentially arranged in the conveying direction, so that the mounting span L of the spacing restricting tool 131 is the innermost side. From the shortest span La formed between the space restricting tools 131a and 131a, a wide span Lb (between the space restricting tools 131b and 131b), Lc (between the space restricting tools 131c and 131c),... However, since the attachment span L (La, Lb, Lc,...) Of the pair of spacing restriction tools 131 is configured to be larger than the attachment spans L1, L2 of the pair of brackets 132 in any case, the hot plate The occurrence of problems associated with the thermal expansion of 130 is suppressed, the replacement of the moving rollers 105L and 105R is facilitated, and the working accuracy of the hot plate holding structure can be increased.

  Next, the operating state of the hot plate holding structure will be described. First, in order to heat and pressurize the plate material W1 to be processed, the rams 151L and 151R are degenerated by the operation of the hydraulic cylinders 150L and 150R (see FIG. 4). As a result, as shown in FIG. 9, the movable-side pressing plate 140F and the adjacent heat plate 130 are gradually opened in the pressing direction. Eventually, the engaging portion 131B of the space restricting tool 131 fixed to the pressing plate 140F and the fixed engaging portion 135b of the connecting tool 135 fixed to the adjacent heat plate 130 come into contact with each other. As described above, the interval between the pressing plate 140F and the heat plate 130 is regulated by the interval regulating tool 131.

  When the pressing plate 140F is further moved in the opening direction from this state, the mutual spacing with the next heat plate 130 is regulated by the next spacing regulating tool 131 in the same manner as described above, and this movement sequentially moves toward the pressing plate 140B on the fixed side. It repeats to the heat plate 130 arrange | positioned. Thus, the space | interval control tool 131 can control the mutual space | interval of each hot plate 130 to a fixed width (pitch), and can be in a press open state (refer FIG. 6).

  And while supporting the to-be-processed board | plate material W1 in an upright state, it carries in along the carrying-in path K with the roller conveyor 160, and inserts the to-be-processed board | plate material W1 between each heat plate 130 (refer FIG. 4). Thereafter, the rams 151L and 151R are extended by the operation of the hydraulic cylinders 150L and 150R, whereby the pressing plate 140F comes into contact with the adjacent heat plate 130. Each hot plate 130 is moved in a direction in which the space between the hot plates 130 is contracted by the pressing plate 140F. The processed plate material W2 formed into a predetermined thickness by pressing and closing the processed plate material W1 between the hot plates 130 and heating and pressing for a predetermined time is carried out by the roller conveyor 160 (see FIG. 5).

  As described above, the moving rollers 105L and 105R are disposed closer to the center (inner side) of the heating plate 130 in the conveyance direction and with a shorter span (tread) than both outer sides in the conveyance direction, so that the heating plate 130 is heated. The eccentric amount of the moving rollers 105L and 105R when expanded is relatively smaller than both outer sides in the transport direction. For this reason, when the moving rollers 105L and 105R move in the guide groove 104a, the edges in the width direction of the moving rollers 105L and 105R are less likely to interfere with both side walls of the guide groove 104a, and smooth movement can be maintained. In this way, the moving rollers 105L and 105R and the guide groove 104a are less likely to interfere with each other, and the gap in the width direction between the moving rollers 105L and 105R and the guide groove 104a can be reduced. Therefore, due to the displacement of the hot plate 130 itself in the transport direction. The backlash can be reduced. In addition to the thermal expansion of the hot plate 130, even when the hot plate 130 is inclined with respect to the transport direction, the smooth movement of the moving rollers 105L and 105R can be maintained in the same manner as described above.
