Description

  The present invention is a horizontal hot press in which a plurality of sheets to be processed such as veneer veneer (hereinafter simply referred to as veneer) and plywood are individually hot-pressed in a vertically aligned state (standing state). It is about improvement.

  Conventionally, using a suitable heat source such as heating steam, heating oil, or an electric heater, a plurality of heating plates heated to a desired temperature are arranged in the vertical direction and supported (held) so as to be movable in the horizontal direction. At the same time, various horizontal hot presses have been proposed for hot-pressing the plate to be processed by inserting the plate to be processed between the hot plates and then pressing each hot plate in the horizontal direction perpendicular to the heating surface. As a typical structure, for example, a structure disclosed in Patent Document 1 can be given.

  Thus, the specific structure of the horizontal hot press disclosed in Patent Document 1 is such that a pair of fixed frames arranged in the front-rear direction (pressing direction of the plate to be processed) are arranged in the vertical direction (standing up of the plate to be processed). Direction) and left and right direction (conveying direction of the plate to be processed), which are arranged in parallel at an appropriate interval and fixedly connected to each other using a pair of upper and lower horizontal beams, and rails laid on the upper pair of horizontal beams A single or a pair of pressing plates are suspended inside one or both of the fixed frames so as to be movable in the front-rear direction via a pair of roll-shaped moving members that engage with each other. A single-sided heating type heating plate is attached inside or inside the single pressing plate and the opposite fixed frame (usually with a heat insulating material in between), and the single-sided heating type heating plate Inside, a plurality of moving members having the same configuration as the moving member are provided. The double-sided heating type hot platen is suspended so as to be movable in the front-rear direction, and an interval regulating member is provided in the vicinity of the moving member so as to regulate the open interval between the hot plates to be constant. By moving the single or a pair of pressing plates in the front-rear direction via a hydraulic cylinder attached to one or both of the frames, a heat plate other than the heat plate attached to the fixed frame is moved in the front-rear direction to generate heat. The hot plate processing and the opening of the plate material to be processed by the panel are alternately performed, and the plate material to be processed is carried in and out through a carrier such as a roll conveyor disposed below the hot platen.

  However, according to the structure as described above, it is sufficient to move each of the heating plates from the position where the heating plates are most separated from each other to a position where the plate material to be processed can be hot-pressed via the pressing plate. It is essential to have a precise and long hydraulic cylinder, so there is a problem that the manufacturing cost of the entire device including the hydraulic pump that can operate the long hydraulic cylinder quickly increases. As a result, the planar occupied space of the entire apparatus (particularly in the front-rear direction) is also long. For this reason, it is assumed that the maximum interval between the heating plates is 50 to 100 mm (generally, an appropriate required maximum interval is determined according to the processing conditions such as the thickness of the plate to be processed and the warpage). If the maximum number of sheets to be treated is 40, the required stroke of the hydraulic cylinder sufficient to perform the heat pressure treatment is about 2 m to 4 m. If the maximum number of sheets to be inserted is 60, the required stroke is about 3 m to 6 m. Therefore, even if a configuration is adopted in which a hydraulic cylinder is provided opposite to each of the pair of fixed frames, as a result, the rear portion of the long hydraulic cylinder is forced to protrude from the fixed frame.

The present invention, the be those developed in order to solve the problems of the conventional horizontal hot pressing, specifically, fixed frame fixedly provided to one longitudinal side of the pressing direction of the processed sheet material And a movable frame provided on the opposite side of the fixed frame and arranged to be movable in the pressing direction along a pair of frame guides disposed on the left and right of the pressing direction, and between the two frames. A pressure plate that is positioned and movable in the pressing direction along a pair of pressure plate guides disposed on the left and right of the pressing direction, and the inner side of either the fixed frame or the movable frame and the pressure plate And a pair of hot plate guides located on the inner side of the single-side heating type hot plate and disposed on the left and right sides of the pressing direction. It is possible to move in the pressing direction along A plurality of double-sided heating type heating plates, an interval regulating member that is disposed at an appropriate position to engage with each of the heating plates, and regulates the opening interval between the heating plates, and each of the heats A support member that supports the lower side of the plate to be processed that is inserted between the heating plates, and an appropriate position that engages the movable frame. A frame moving mechanism that moves forward and backward in the pressing direction, a hydraulic cylinder that is attached to one of the two frames, moves the pressure plate forward and backward in the pressing direction, and the both An appropriate number of hooking portions provided on the left and right sides of either one of the frames, and hooks that can engage with the hooking portions when the movable frame approaches a fixed distance to the fixed frame. Has a part on the tip side, An appropriate number of hooked arms each having a proximal end pivotally attached to the left and right of the frame opposite to the frame having the hooking portion; and a swing mechanism for swinging the hooked arm. The horizontal hot press (Claim 1) characterized in that the movable frame and the frame guide are engaged with each other via a roller. (Claim 2) The horizontal hot press according to claim 1 or 2, further comprising a hot plate guide, and a press plate being engaged with the hot plate guide serving as the press plate guide via a single-side heating type hot plate. The horizontal hot press (Claim 4), the fixed frame and the movable frame according to claim 1 or 2 or 3, wherein 3) and a hot platen and a hot plate guide are engaged via a roller. Two hooks on each side and two A horizontal hot press (claim 5) according to any one of claims 1 to 4 is provided.

  When the horizontal hot press according to claim 1 of the present invention is compared with the conventional horizontal hot press, the frame guide of the movable frame, the frame moving mechanism, the hooked arm, the swinging mechanism and the like are required, but the frame moving Through the mechanism, the movable frame is brought close to the fixed frame to a predetermined distance (for example, a distance at which all the plate materials to be processed and the heating plate approach almost closely), and then, through the swing mechanism, After swinging the hook part so that it engages with the hook part, pressing each hot platen via the hydraulic cylinder and pressurizing plate allows the plate material to be processed to be subjected to the desired hot-pressure treatment. In addition, the required stroke of an expensive hydraulic cylinder that requires precision can be significantly shortened compared to the conventional method, and the capacity of the hydraulic pump can be reduced, so that overall manufacturing costs can be reduced. Next, since Thus even be shortening the hydraulic cylinder, it made possible also to narrowing of planar footprint.

  Thus, in the horizontal hot press according to the present invention, it is possible to adopt an engagement form in which the movable frame is directly placed on the frame guide and to slide back and forth. As disclosed in FIG. 2, if the engagement form via the roller is adopted, smooth movement is possible, and the frame moving mechanism can be simplified and saved in power, which is effective. Further, although it is possible to adopt a configuration in which the pressure plate guide and the heat plate guide are separately provided, as disclosed in claim 3, the pressure plate guide and the heat plate guide are also provided. Accordingly, it is effective to employ a configuration in which the pressure plate is engaged with the pressure plate guide serving as a heat plate guide, since the structure is further simplified. Further, as in the case of the movable frame, the hot platen is placed on the hot platen guide without using the roller, as disclosed in claim 4, by engaging the hot platen guide with the hot plate guide. As compared with the case where the engagement form is slid back and forth, smooth movement is possible, which is generally effective. In addition, the number of hooked arms (and hooked portions) disposed in consideration of the stability of engagement between the two frames and the simplicity of the mechanism during hot pressing, as disclosed in claim 5. It is appropriate that there are four (four places), two (two places) on each side of both frames.

It is provided so as to be movable in the front-rear direction along a hot plate guide 5 described later via a roller 4b attached to 4A. Based on the control of a control mechanism (not shown), an appropriate arrangement provided on the fixed frame 1A is provided. The operation of several hydraulic cylinders 3a (two in the embodiment, which can be changed as necessary) is obtained and moved forward and backward in the pressing direction of the plate to be processed as appropriate.

  Reference numeral 5 denotes an inverted L-shaped hot plate guide also serving as an inverted L-shaped pressure plate guide, one end of which is fixed to the fixed frame 1A and the other end of the base 2 via a roller 4b mounted on the upper surface. The forward / backward movement of the single-sided heating type hot platen 4A and the double-sided heating type hot platen 4B integrated with the pressure platen is guided. If necessary, it is possible to further stabilize the guide by providing the guide groove 5a as in the embodiments described later.

  Reference numerals 6 and 6a denote two sets of interval regulating members each provided separately on the adjacent heating plates 4A and 4B or adjacent heating plates 4B, and each of the right and left in the pressing direction of the plate to be processed. An appropriate number (at least the same number as the number of processed plate materials to be processed) is attached (the embodiment is attached to the side surface of the heat plate), and the access between the heat plates is unconditionally allowed (see FIG. 6), and The separation between the heat plates is restricted so as to allow only a certain limit.

  7 is a strip-shaped support member, and when the heating plates 4A and 4B are separated from each other, a plurality of strips (implemented) are formed so as to block the intervals between the heating plates 4A and 4B from below. In the example, Article 7) is attached above the base 2 via a connection support 7a, and supports the lower side of the veneer 11 inserted between the heating plates 4A and 4B. Prevent falling from inside. Incidentally, when the plate to be processed is a relatively soft plate such as a single plate, it is unsuitable for loading (and unloading) between the hot plates directly from the side (left and right direction). Therefore, an appropriate sandwiching and transporting mechanism, not shown, is used, for example, by using a sandwiching and transporting mechanism in which a plate member is sandwiched and transported by a sandwiching member suspended from above, as shown by an arrow in FIG. It is desirable to hold (and carry out) by sandwiching from above, and in the case of a plate material having anisotropy in strength, such as a single plate, it is desirable that the direction having a relatively high strength is directed in the vertical direction. .

  Reference numeral 8 denotes a frame moving mechanism having a drive source 8g including a shaft 8a, a bearing 8b, a chain wheel 8c, an endless chain 8d, a locking tool 8e, a connecting tool 8f, an electric motor with a speed reducer, etc. Based on the control of the control mechanism, the driving source 8g is driven forward and backward to move the movable frame 1B forward and backward as appropriate.

  9 is a hook part 9a that engages with the hook part 1a of the movable frame 1B on the tip side (however, the part that is substantially directly engaged with the hook part 1a corresponds to the inner side surface of the hook. The base end side is pivotally supported via a pivot bearing 9b attached to the fixed frame 1A and a pivot 9c fitted to the pivot bearing 9b. Based on the control of a control mechanism (not shown), an operation of a swing mechanism 10 described later is obtained, and the single plate 11 is pressed prior to the heat and pressure treatment of the single plate 11 by swinging as indicated by the arrow in a timely manner. The locking of the fixed frame 1A and the movable frame 1B with respect to the direction is made possible, and the locking is made unnecessary after the end of the hot press process.

  Reference numeral 10 denotes an oscillating mechanism having an operating member 10a composed of a fluid cylinder and the like, a connector 10b, a support bearing 10c, and the like. Rock.

  The horizontal hot press according to the present invention is configured, for example, as described above. Initially, each brazed arm 9 is moved outward via a swing mechanism 10 based on control of a control mechanism (not shown). The movable frame 1B is attached to the movable frame 1B via the spacing regulating members 6 and 6a by swinging and waiting at the standby position indicated by the solid line and by retracting the movable frame 1B to the front end side via the frame moving mechanism 8. The plurality of double-sided heating type heating plates 4B engaged with the single-sided heating type heating platen 4A are sequentially moved to the front end side, and the adjacent heating plates 4A, 4B and the heating plates 4B are moved to each other. It is set as the state which mutually separated (refer FIGS. 2-4).

  The single plate 11 to be processed is sandwiched separately using an appropriate sandwiching and transporting mechanism (not shown), and once from the side of the upper part of the horizontal hot press, once above the interval between the heating plates 4A and 4B. After being transferred to the heating platen, the platen is lowered between the heating plates 4A and 4B, and the holding is simultaneously released at an appropriate position, preferably just before the lower side comes into contact with the support member 7 (FIGS. 1 and 3). reference).

  Thereafter, based on the control of the control mechanism, the movable frame 1B is advanced to the rear end side via the frame moving mechanism 8 as illustrated in FIGS. 4B stops moving forward at a position where it lightly contacts with all the single plates 11 or immediately before it, and then, through the swing mechanism 10, is a standby position indicated by a dotted line in FIG. Each of the arm 9 with the hooks is moved to the engagement position indicated by the solid line and then the hydraulic cylinder 3a is operated to move the heating plates 4A and 4B through the pressurizing plate 3. The single plate 11 is pressed against the frame 1B and subjected to hot-pressure treatment.

  After applying the desired heat and pressure treatment to each single plate 11, the operation of the hydraulic cylinder 3 a is returned based on the control of the control mechanism, and each barbed arm 9 is connected to the engagement mechanism 10 via the swing mechanism 10. The single-sided heating type attached to the movable frame 1B via the spacing regulating members 6 and 6a by swinging from the combined position to the standby position and further retracting the movable frame 1B to the front end side via the frame moving mechanism 8. A plurality of double-sided heating type heating plates 4B engaged with the heating platen 4A are sequentially moved to the front end side, and the adjacent heating plates 4A and 4B are returned to a separated state.

  After that, each single plate 11 that has been subjected to hot-pressure treatment is sandwiched separately using an appropriate sandwiching and transporting mechanism, and once transported to above the interval between the respective heating plates 4A and 4B, it is opposite to the time of loading. Carry out to the side of the upper side. In addition, preferably, after the plurality of single plates 11 to be subjected to the heat and pressure treatment next are transferred to the upper part of the interval between the respective heating plates 4A and 4B by the holding conveyance mechanism, It is lowered in between and the clamping is released at an appropriate position. Thereafter, by repeating the same operation, a desired hot-pressure treatment can be performed on a plurality of single plates each time.

  On the other hand, when the plate to be processed is a strong plate such as a plywood, it is easy to carry (and carry out) between each hot platen directly from the side (left and right direction). As in the embodiment illustrated in FIGS. 7 to 10, a configuration different from the configuration of the above-described embodiment can be adopted.

  That is, as illustrated in FIGS. 7 to 10, instead of the movable frame 1 </ b> B in the embodiment illustrated in FIGS. 1 to 4, the movable frame 1 </ b> A has window-like hooking portions 1 a on the left and right sides of the upper and lower surfaces. In addition to the frame 1C, the fixed frame 1A is provided with hooked arms 9 on the left and right of the upper and lower surfaces, respectively, and the swinging mechanism 10 is attached to each of the hooked arms 9, so that a standby position and a dotted line indicated by solid lines It is comprised so that it may rock | fluctuate alternately between engagement positions shown by.

  Further, instead of chamfering above the heating surface of each heating platen 4A, 4B, a saddle-like processed plate material guide 4d is attached to either the left or right side surface of each heating platen 4A, 4B, and a roller support 4c. The roller 4b is attached to each desired heating platen 4A, 4B, and the height of the heating plate guide 5 is set higher than the height of the heating plate guide 5 of the embodiment illustrated in FIGS. By setting the distance restricting members 6 and 6a to the upper surface side of each of the heating plates 4A and 4B, the left and right sides of each of the heating plates 4A and 4B are completely opened. As illustrated in FIG. 10, the guide can be further stabilized by providing a guide groove 5 a in the hot plate guide 5.

  Furthermore, instead of the belt-like support member 7 and the connection support 7a, a plate material transport mechanism 12 including a transport roll 12a that also serves as a support member, a bearing 12b, a drive source (not shown), and the like is provided on the base 2. A configuration in which the plywood 14 which is a plate to be processed can be directly carried in (and carried out) between the heating plates 4A and 4B from the side (left and right direction) of the heating plates 4A and 4B by being attached to the upper side. And

  The horizontal hot press according to the present invention may have, for example, the above-described configuration. Like the above-described embodiment, the horizontal hot press is initially set on the upper side via the swing mechanism 10 based on the control of the control mechanism. The barbed arm 9 is swung up and the lower barb arm 9 is swung down to stand by at the standby positions indicated by solid lines, and the movable frame 1B is moved back to the front end side via the frame moving mechanism 8. As a result, a plurality of double-sided heating type hot plates 4B, which are engaged with the single-sided heating type hot platen 4A attached to the movable frame 1B via the spacing regulating members 6 and 6a, are sequentially moved to the front end. It moves to the side and it is set as the state which mutually separated the adjacent heat | fever platen 4A, 4B and heat | fever platen 4B.

  Then, the plywood 14 to be subjected to the heat pressure treatment is subjected to an appropriate plate material transfer mechanism, for example, a plate material transfer mechanism 13 having a configuration according to the configuration of the plate material transfer mechanism 12 and the plate material transfer mechanism 12, as indicated by an arrow in the drawing. From the side of each heating platen 4A, 4B, it is carried directly between each heating platen 4A, 4B. After that, although not shown in the figure, based on the control of the control mechanism, via the frame moving mechanism 8, The movable frame 1C is advanced to the rear end side, and the advancement is stopped at an appropriate position, for example, at a position where each of the heating plates 4A and 4B is in light contact with all the plywoods 14 or at a position immediately before it. 9, after swinging each brazed arm 9 that has been waiting at the standby position indicated by the solid line in FIG. 9 to the engagement position indicated by the dotted line, the hydraulic cylinder 3 a is moved. By operating it, each pressure platen 4A via the pressure platen 3, B and presses the on the movable frame 1B, each plywood 14 heat and pressure treatment.

  After the desired heat and pressure treatment is performed on each plywood 14, the operation of the hydraulic cylinder 3 a is returned based on the control of the control mechanism, and each barbed arm 9 is engaged with the engagement via the swing mechanism 10. The single-sided heating type attached to the movable frame 1C via the spacing regulating members 6 and 6a by swinging from the position to the standby position and further retracting the movable frame 1C to the front end side via the frame moving mechanism 8. A plurality of double-sided heating type heating plates 4B engaged with the heating platen 4A are sequentially moved to the front end side, and the adjacent heating plates 4A and 4B are returned to a separated state.

  Thereafter, the plywood 14 subjected to the heat and pressure treatment is carried out to the side opposite to the time of carrying in via the plate material transport mechanism 12 and the plate material transfer mechanism 13. In addition, preferably, a plurality of plywoods 14 to be subjected to the heat and pressure treatment next are carried into the respective hot plates 4A and 4B through the plate material transfer mechanism 13 and the plate material transport mechanism 12 together. Thereafter, by repeating the same operation, a desired heat and pressure treatment can be applied to a plurality of plywoods each time.

  As is clear from both of the above embodiments, the horizontal hot press according to the present invention requires a frame guide of a movable frame, a frame moving mechanism, a hooked arm, a swinging mechanism, and the like. Then, the movable frame is moved close to the fixed frame to a predetermined distance, and then the swinging mechanism is swung so that the hooked part of the hooked arm is engaged with the hooking part, and then the hydraulic cylinder and the pressure plate are moved. By pressing each hot platen, the plate material to be processed can be subjected to the desired hot-pressure treatment, so that the required stroke of an expensive hydraulic cylinder that requires precision can be significantly shortened compared to the prior art. (It is sufficient to change the thickness of the plate to be processed and the number of processed sheets is sufficient.) And the capacity of the hydraulic pump can be reduced, so overall the manufacturing cost of the entire device can be reduced. Conversion Possible and will, Thus also because the hydraulic cylinders may be shortening, it made possible also to narrowing of planar footprint. For this reason, the required stroke of the hydraulic cylinder in such a configuration is sufficient to cope with a change in the thickness of the plate to be processed with a slight margin. For example, 60 to 60 plywood having a thickness of 2 to 12 mm is sufficient. When processing sheets, there is no problem with 12 × 60 + α≈0.75 m, and the length can be reduced to 1/4 to 1/8 of the conventional one.

  Further, in the horizontal hot press according to the present invention, it is possible to adopt a configuration in which the movable frame is directly placed on the frame guide and can be slid back and forth. As described above, if the engagement form through the rollers is adopted, smooth movement is possible, and the frame moving mechanism can be simplified and power saving, which is effective. In addition, although it is possible to adopt a configuration in which the pressure plate guide and the heat plate guide are separately provided, as in both the above-described embodiments, the pressure plate guide is also used as a pressure plate guide and is provided via a single-side heating type heat plate. If the structure in which the pressure plate is engaged with the pressure plate guide also serving as the pressure plate guide is adopted, it is effective because the structure is further simplified. In addition, as in the case of the movable frame, the hot plate is also placed on the hot plate guide without the roller, as in both the above embodiments, by engaging the hot plate with the hot plate guide. Compared with the case of adopting an engagement form that slides back and forth, smooth movement is possible, which is generally effective. In addition, from the viewpoint of the stability of engagement between the two frames at the time of hot pressure, the simplicity of the mechanism, etc., the number of hooked arms (and hooked portions) is as in both the above embodiments. It is appropriate to use four (four locations), two (two locations) on each side of both frames.

  In both of the above embodiments, a pressure plate is provided on the fixed frame side and pressed using a hydraulic cylinder, but conversely, a pressure plate is provided on the movable frame side, There is no problem even if the cylinder is pressed. Also, as shown in the figure, if the main body portion of the hydraulic cylinder is provided so as to be housed inside the frame, there is an advantage that the space occupied by the device can be very narrow, but the rib placement position that ensures the rigidity of the frame For example, when the maintenance and inspection of the hydraulic cylinder is performed or the size (width and length) of the plate to be processed is changed, the position of the hydraulic cylinder is moved. It is inconvenient or inconvenient when adopting a configuration to do so. Therefore, although not shown in the drawing, if necessary, the hydraulic cylinder used in the present invention has a short required stroke itself even if the hydraulic cylinder body is provided between the pressure plate and the frame so as to be exposed. There is no particular problem in practical use.If such a configuration is adopted, the occupied space is somewhat widened, but there is almost no restriction on the position of the ribs. Alternatively, it is convenient when adopting a configuration in which the arrangement position of the hydraulic cylinder is moved.

  In both of the above embodiments, the hooked arm is provided on the fixed frame side and the hooked portion is provided on the movable frame side. Conversely, the hooked arm is provided on the movable frame side. At the same time, there may be a configuration in which a hooking portion is provided on the fixed frame side. In addition, as the hooking portion that engages with the hook portion of the hooked arm, the window-like hooking portion is exemplified, but the shape of the hooking portion is not limited to the window shape, and the illustration is omitted. For example, even if it is a hook-like hooking part, the point is that when the plate material to be processed is subjected to hot-pressure processing, the relative distance between the fixed frame and the movable frame is regulated to be constant for a while. Any form that can engage with the hook part is sufficient, and there is no particular restriction on the form of the hooked arm. In short, any form that has a hook part that can be stably engaged with the hooking part is sufficient.

  In both of the above embodiments, the movable frame is simply placed on the frame guide via the roller. However, if necessary, the movable frame is attached to the heating plate in the example of FIG. In the same manner as the engagement between the roller and the guide groove provided on the hot plate guide, it is possible to further stabilize the guide by providing a guide groove in the frame guide, although illustration is omitted. If necessary, instead of the guide groove, an appropriate number of rails are attached on each guide, and a hooked roller that engages with the rail is attached to each heating plate or movable frame, It does not matter if the guide is stabilized.

  Further, the form of the spacing regulating member is not limited to the form shown in both the above-described embodiments. Although not shown, for example, a bar with a stopper attached to one member is drilled in the other member. A configuration in which the amount of movement of the bar material passing through the hole is uniformly regulated by the stopper, or, for example, a chain in which both ends are fixed to different heating plates, or both ends Are attached to different heating plates, and the center plate is connected to each other by a knuckle joint. It is sufficient to use a member having a function that allows the separation between the heating plates only to a certain limit, and there is no particular limitation on the form of the interval regulating member.

  Also, the form of the support member is not particularly limited, but a form in which wastes such as wood chips that are missing from the processed plate material do not stay and accumulate is preferable. Each is relatively long and narrow, and is preferably arranged in multiple rows with gaps through which debris can fall.

  In addition, the heating surface of each hot plate is usually formed in a smooth shape, but if necessary (for example, when hot pressing is performed to dry an undried veneer), An appropriate number of narrow grooves with appropriate cross-sectional width and depth are drilled on the heating surface of each hot platen, which is effective in facilitating the discharge of steam generated from the plate material to be treated. However, the extending direction of the narrow groove is preferably a direction intersecting the fiber direction of the single plate.

  In addition, the shape of the lower end portion of each heating plate is not necessarily required to be linearly positioned above the support member as in the illustrated example, and is not shown in the figure. In other words, only the portion facing the support member is somewhat scraped, in other words, the portion other than the portion facing the support member is somewhat lower than the portion facing the support member. If the lower end portion of each heating plate is made into such a shape, it is possible to project a large portion of the lower end portion of the plate to be processed (other than the vicinity of the portion supported by the support member). This part is effective for equalizing the processing.
