Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a horizontal multi-stage press in which a plurality of heat plates are disposed between left and right frames that can be freely opened and closed. From the loader side to the hot plates, the plates to be treated, such as plywood, decorative boards, veneer veneers, etc., to be heated and pressed are carried in, and from the hot plates to the unloader side, the treated boards after being heated and pressed are carried. This relates to a device for removing a body.

``Prior art'' The multi-stage press, which is usually used mainly in the plywood manufacturing process, has a movable platen that can be raised and lowered by a ram cylinder installed in the lower frame, and is equipped with multiple stages of hot plates between the upper and lower frames. After inserting and placing the plates to be processed between these hot plates, the Machido Iwa is raised and the hot plates above are successively pushed up, starting with the lowest hot plate, and the press is closed. A treated plate was obtained by heating and pressing for a period of time.

However, in this type of multi-stage press having multiple upper and lower heating plates, when supporting each stage of heating plates,
A system is adopted in which support claws are attached to the four corners, and these support claws are sequentially placed on ladder-like supports attached to pillars. Therefore, when determining the thickness of each stage of hot plates, in addition to the strength required for heating and pressing the plate to be processed, which is the main purpose, consider the strength corresponding to the deflection and bending caused by the distance between the supporting points. Taking this into account, the thickness is greater than necessary in order to provide rigidity.

Furthermore, arranging hot plates that are thicker and heavier than necessary in multiple stages means that the upper and lower parts of the plate placed on the hot plate are Not only does this increase the variation in pressurizing force at each stage, resulting in poor adhesion and thinning of the treated plate, but also the diameter of the ram cylinder, which is the means to raise and lower the hot plates at each stage, and the supply of fluid to the cylinder. This caused an increase in the pump capacity and the load on the fluid pressure unit, forcing the multistage press to become larger.

For this reason, by adopting a horizontal multi-stage press with hot plates arranged side by side in the horizontal direction, as opposed to a vertical multi-stage press with multiple hot plates arranged above and below, the variation in pressurizing force can be corrected.
Attempts have been made to eliminate poor adhesion to processed plates after heating and pressurizing, to reduce the weight of hot plates, or to downsize fluid pressure units and the like. In parallel, between the hot plates of the horizontal multi-stage press, which are arranged side by side at equal intervals when the press is opened,
A device is required to carry in the plate to be processed in an upright position, or to carry out a processed plate in an upright position.

In order to overcome the above-mentioned situation, the applicant of the present application
Publication No. 9118 (filed on May 29, 1980), JP-A-60-250901 (published on December 11, 1982), title of invention: "Devices for loading and unloading plates in horizontal multi-stage presses" As shown in FIGS. 1 and 2 attached to the specification of the present application, there are directions for carrying in and carrying out the plate 2 to be processed into the horizontal multistage press 1, and for carrying out the processed plate 3. Orthogonally supporting a chain conveyor 4 and a belt conveyor 5 having an upper conveying surface higher than the upper conveying surface of the chain conveyor 4, running in parallel, and controlling the rotation of both conveyors at approximately the same speed; Further, a loader 1ljI7 or an unloader shelf 8, which is in phase with the spacing of the hot plates 6 arranged in parallel when the press is opened, is fixed to the chain conveyor 4, and is further provided above the belt conveyor 5. To provide a device for loading and unloading plates in a horizontal multi-stage press l equipped with an loading conveyor 9 or an unloading conveyor 10 that can freely move in and out of the conveying surface,
When the press is opened, the loader m7 of the plate 2 to be processed
It became possible to carry the processed plates 3 between the hot plates 6 and the unloader shelf 8, and some results were obtained.

"Problems to be Solved by the Invention" However, the individual veneer veneers constituting the plate body 2 to be heated and pressurized are subject to considerable warping, bending, and bending.
There are twists, etc., and depending on the difference in the type of raw wood mochi, these may occur noticeably during or immediately after cutting the veneer veneer, and these veneer veneers may be polymerized and temporarily bonded. The plate body 2 to be processed is driven by the carry-in conveyor 9 and the conveyor 11 as the same conveyance surface, and the loader fence 7
If the front side of the plate 2 to be processed collides with the insertion guide 12 of the hot plate 6 when it is carried into the gap between the hot plates 6, or even if the front part is carried in, the hot plate 6
The particles become clogged within the space and cannot be completely carried into the hot plate 6, making it impossible to heat and pressurize them.

Furthermore, as described above, the treated plate 3 after heating and pressurizing may warp due to the stress during heating depending on the species of the raw wood, and the treated plate 3 may become sandwiched between the hot plates 6. , is pushed down onto the conveyor ll by the pushing body 13, and when the conveyor 11 and the carry-out conveyor 10 work together to carry it out between the unloaders fl18, it gets stuck within the spacing of the hot plates 6 and collides with the unloader fl8. As a result, the processed plate 3 cannot be completely removed.

Under these circumstances, the applicant further filed the patent application No. 61-2864.
Publication No. 37 (filed on December 1, 1986), the title of the invention is "A device for transporting plate bodies in a horizontal multi-stage press", in which all or some of the rolls constituting the conveyor, the carry-in conveyor, and the carry-out conveyor are , by arranging a protrusion that locks at the bottom of the plate, and causing the bottom of the plate in an almost upright state to lock on the protrusion to apply forced feeding,
Bending, warping, etc. of the plate body 2 to be treated and the treated plate body 3 were dealt with.

However, the plate itself is relatively heavy,
If the width of the plate is thick, it will be placed on the protruding object under its own weight, and the locking area will be large, so good locking and conveyance will be achieved, but the opposite will occur. In addition, the plate itself is relatively lightweight, and if the width of the plate is thin, it will be lightly placed on the protrusion, and the stopping area will be small, so it will not be affected by bending, warping, etc. , the plate body lifts up during locking and conveyance, resulting in the inability to achieve the intended purpose.

"Means for Solving the Problems" In view of the above, the present invention provides a horizontal multi-stage press comprising a plurality of rows of hot plates that can be opened and closed at equal intervals between left and right opposing frames. , a pinch roll is positioned below each stage hot plate, and is supported vertically within the interval between each stage hot plate when the press is opened, and engages with both sides of the lower part of the plate, which is in an almost upright state, to pinch and feed it. By carrying the plate to be processed into the space between the hot plates when the press is opened and carrying out the processed plate, even if the plate to be processed and the processed plate are lightweight,
Even if the width of the material is thin and bends, warps, etc. occur, the material can be carried in and taken out easily due to the clamping and feeding force.

``Example'' Hereinafter, an example of the present invention will be described based on the accompanying drawings, starting from the configuration. It should be noted that parts that have already been explained will be given the same numbers and will not be explained repeatedly.

First, the configuration of the horizontal multi-stage press 1 will be explained in more detail.

Frames 16.17 are installed on the left and right sides via a pair of upper and lower cross beams 14.15 arranged at arbitrary intervals in the vertical and longitudinal directions, and rails 18 laid on the upper cross beams 14. A ruler 19 is attached to one of them. Between the rails 18, a plurality of heat plates 6 are attached, protruding from both sides of the upper part, and movable. A board 22 is suspended. A plurality of fluid cylinders 23 are fitted into the left frame 16 at approximately equal intervals, and the tips of their rams 24 are absorbed by the movable platen 22, and the plates 2 to be processed are An insertion guide 12 having a substantially triangular cross section with a sharp tip is formed on the side surface located on the carry-in side.

Further, brackets 25 are attached to the left and right upper and lower parts of the hot plate 6 and the movable platen 22, or both upper and lower sides as shown in the figure, that is, near the four corners that do not interfere with the loading and unloading of the plate 2 to be processed, A gate-shaped regulating device 26 is bridged between these adjacent brackets 25, one end of which is absorbed into the bracket 25, and the other end is a free end, so that the free end of the regulating device 26 is attached to the bracket 25 when the press is released. Lock and heat plate 6
In addition, the left and right spacing of the movable platen 22 is maintained evenly.

Next, a pair of notch grooves 27 are bored at an arbitrary interval in the lower part of the hot plate 6, and a plurality of belts supporting the plate 2 to be processed or a plurality of belts as shown in the figure are placed below the notch grooves 27. A conveyor 11 consisting of rolls 28 is arranged between machine frames 29 on the upper cross beam 15.

Furthermore, on the unloading side of this conveyor 11, there is also a stopper 30 whose stopping position is movable in the conveyance direction by means of a screw mechanism and fluid movement supported on the upper cross beam 15 as appropriate. In between, a pair of push-up bodies 31 intervening in the pair of notch grooves 27 are arranged so as to be able to move in and out of the conveyance surface of the conveyor 11 and have a length that is approximately equivalent to the length of the hot plates 6 of all stages when the press is opened. On the other hand, a pair of connecting beams 32 are arranged between the left and right frames 16 and 17 so that they can be raised and lowered by fluid movement. Push bodies 13 are attached at every interval.

On the loading side of the horizontal multi-stage press 1 for the plate bodies 2 to be processed and on the unloading side of the processed plate bodies 3, there is a carrying device 3 as shown below.
3. An unloading device 34 is provided respectively.

That is, a pair of endless chain conveyors 4 are arranged at arbitrary intervals on a frame 35, and a loader shelf 7 or an unloader shelf without the regulating member 37 installed on the upper part is connected via the attachment 36 of the chain conveyor 4. 8 are installed at intervals of the hot plates 6.

On the other hand, at the inner position of each chain conveyor 4, a large diameter pulley is arranged at each folded part to transfer the plate 2 to be processed or the processed plate 3 at each folded part, or
Alternatively, as shown in the illustrated example, a belt conveyor 5 is provided which rotates at approximately the same speed as the chain conveyor 4 and supports the lower end of the plate 2 to be processed or the processed plate 3. Further, on the pedestal 35, an incoming conveyor 9 or an outgoing conveyor 10 is disposed, which can freely move in and out of the conveying surface of the belt conveyor 5, and which is on the same conveying surface as the conveyor 11 at the upper limit.

Next, the areas to be further processed or located between the lower end surface of the hot plate 6 and the conveyance surface of the conveyor 11 in the vertical direction, and at the intervals between the hot plates 6 of each stage when the press is opened in the left and right direction. The rolls 2 constituting the conveyor 11 are arranged at arbitrary intervals in the conveying direction of the processed plate 2.3.
Pinch rolls 38 that pinch and feed the lower part of the plate 2°3 that is to be processed or has been processed in an almost upright state from within the 8 interval.
(In the illustrated example, two locations are installed, but the number is arbitrary depending on the size, weight, and width of the processed plates 2 and 3.), and the machine frame 29 It is rotatably supported vertically on the top. The interval between the pinch rolls 38 is adjustable within the range of the interval between the hot plates 6 when the press is opened. For example, in the embodiment shown in FIGS. A slide plate 39 is disposed on the machine frame 29 and moves forward a certain distance by screwing or fluid motion, and when the slide plate 39 is released, the number of six heating plates installed at every interval of six hot plates is determined. Almost the same number of bases 40. A driven side roll 41 for sandwiching the plate is attached to one end via a shaft part, a driving side roll 42 is arranged at the other end, and a pin is installed in the center. 43, and the slide plate 39 is advanced a certain distance when the plate body is held and fed, and the driven side rolls 41. The rolls 42 on the drive side are brought close to each other using the pin 43 as a fulcrum, and the chain 44 is driven from the gear 45 fitted on the pin 43 to the gear 46 fitted on the roll 42 on the drive side.
In addition, in order to reliably transmit the rotational force, the engaging surface has knurled grooves or is wrapped with an elastic material such as rubber to create a high friction state. It is desirable to do so.

Next, the action will be explained.

When the fluid cylinder 23 is operated to retract the ram 24, the movable platen 22. The heat plates 6 at each stage are moved along the rails 18 between the upper cross beams 14 via the moving members 21, with the − side kept in a parallel state by the engagement portions of the ruler 19 and the engagement portions 20. During this movement, the hot plate 6 located at the left end
The free ends of the regulating devices 26 contact the brackets 25 of the adjacent heating plates 6 at the four corners of the brackets, thereby sequentially regulating the maximum opening of the brackets 6, thereby maintaining the equal left-right spacing between the heating plates 6 of each stage. , the press becomes open.

During this time, in the carrying-in device 33, the chain conveyor 4,
By driving the belt conveyor 5 or pulley, each time the loader shelf 7 rises from the insertion surface, one plate 2 to be processed is inserted, and the plate 2 to be processed is inserted between each loader shelf 7. is fully loaded, and each loader shelf 7 is placed on standby at a position that is in the same phase as the spacing between the hot plates 6 when the press is opened.

When the press is opened, the carry-in conveyor 9 protrudes from the conveyance surface of the chain conveyor 4 or the belt conveyor 5, and supports the lower end of the plate 2 to be processed on the same conveyance surface as the conveyor 11.

Next, first, the carry-in conveyor 9 is driven to pinch the plate 2 to be processed between the pinch rolls 38 located at the rear end of the hot plate 6 in the conveying direction. At this time, the pinch rolls 38 and the conveyor 11 are driven synchronously and at the same speed as the carry-in conveyor 9, and when the lower both sides of the front end of the plate 2 to be processed are sandwiched between the pinch rolls 38, Thereafter, by the pinching rotational force of the pinch rolls 38, the heating medium is supplied and carried simultaneously between the hot plates 6 of each stage, which are maintained at the required temperature.

When the plate 2 to be processed is carried in, the lower front end of the plate 2 is supported by rolls 28 arranged at appropriate intervals.
Also assisted by the rotational force of the roll 28, the next pinch roll 3
8, and the center position in the conveying direction reaches the position of the stopper 30, which is set so that the center position in the conveying direction reaches the center position in the front-rear direction of the hot plate 6 of each stage. At this time, a detector such as a phototube (
(not shown) detects this and stops the driving of the carry-in conveyor 9, conveyor 11° pinch roll 38. Also, if the stopping position of the plate 2 to be processed shifts forward, The stopper 30 is swung from the retracted position to the stop position to uniformly align the front ends of the plates 2 to be processed that have been carried in between the hot plates 6 of all stages.

When it is detected that all the plates 2 to be processed have been carried into the space between the hot plates 6 from the loader fences 7 of all stages, the carry-in conveyor 9 descends to the lower limit position, and in preparation for the next operation, the above-mentioned process is carried out. As shown, the plate 2 to be processed is inserted between each loader fence 7. Moreover, if the drive of the conveyor 11 is stopped and the push-up body 31 is made to protrude from below the conveyance surface into the notch groove 27,
The plate 2 to be processed on the conveyor 11 is lifted up and inserted between the hot plates 6. As shown in FIG.
It is also possible to use it instead of this push-up body 31.

Under this condition, the operation of the fluid cylinder 23 causes the ram 2 to
When the ram 24 is expanded, the press is closed contrary to the above description, and the plate 2 to be treated is heated and pressurized to become the processed plate 3.9 After heating and pressurizing, when the ram 24 is contracted, the heat The plate 6 and the movable platen 22 move from the hot plate 6 located on the right frame 17 to the brackets 25 of the adjacent hot plate 6 at the four corners by the engagement movement of the movable member 21 and the rail 18. The pressing body 31 is brought into contact with the heat plates 6 in order to equalize the left and right spacing of each stage, and the press is opened.
A pushing body 13 is interposed between each stage of hot plates 6, and the lower end of the treated plate body 3 after heating and pressurization is pushed down onto the conveyor 11 through pinch rolls 38 which are opened up to the distance between the hot plates 6. During this time, in the unloading device 34, each empty unloader shelf 8 is placed on standby at a position with the same phase as the interval between the hot plates 6 when the press is opened, and the unloading conveyor 10 is moved to the chain conveyor 4 or the belt conveyor 5. It is made to protrude from the conveyance surface of the conveyor 11 and is kept on standby on the same conveyance surface as the conveyor 11.

The processed plate 3 pushed down onto the conveyor 11 is moved toward the space between the unloader shelves 8 of each stage due to the drive after the pinch rolls 38 are shortened and closed, and the conveyor 11 and the carry-out conveyor 10 are driven synchronously. - They will be carried out all at once. At this time, since the pinching rotational force of the pinch rolls 38 is transmitted to the lower end portion of the processed plate 3 as described above, even if the processed plate 3 is warped after heating and pressurizing. Even if it is, it is forcibly carried between the unloader shelves 8.

When it is detected that all the processed plates 3 have been transferred from between the hot plates 6 of all stages to between the unloader shelves 8, the plates 2 to be processed are transferred from the carry-in conveyor 9 to between the hot plates 6 as described above. is carried in, and the drive of the carry-out conveyor 10 is stopped, and at the same time, it is lowered to the lower limit position, and the processed plate 3 is
The lower end of the plate body 3 is supported on a chain conveyor 4 or a belt conveyor 5, and when the unloader shelf 8 is folded down at the folding position, the processed plate body 3 is taken out.

In this embodiment, the pinch rolls 38 are disposed at two locations in the conveying direction, but especially the unused l! ! If one type of raw wood is used as a raw material and bending, warping, etc. occur more significantly, it is optional to increase the number of pinch rolls 38 to increase their forced driving force.

Furthermore, although the hot plate 6 and movable platen 22 of the horizontal multi-stage press 1 in this embodiment are suspended from both sides of the upper part for convenience, rails 18' are also laid on the upper cross beam 15,
By supporting at least the upper or lower part of the upper and lower rails 18, 18' so as to be able to slide along the upper cross beam 14 or the upper cross beam 15, and by resiliently mounting the moving member 21, The configuration may be such that the hot plate 6 and the movable platen 22 are elastically supported at four points 9. For example, one embodiment of this structure will be explained based on the front view shown in FIG. 7. It is slidable along the guide surface 47 of the casing 15, and fittings 48 are accommodated on the upper surface of the upper cross beam 15 and the lower surface of the lower rail 18' facing each other at appropriate intervals. A spring member 49 is fastened and connected between 48,
Under normal conditions, the lower rail 18' is pressed down with a constant pressure. Although not shown, swing members are attached to the lower surface of the upper cross beam 14 and the upper surface of the upper rail 18, so that the upper rail 18 can freely slide along the guide surface of the upper cross beam 14, and the spring member It is also possible to change the biasing force to fluid pressure or the like.

"Effects" As described above, according to the present invention, in a horizontal multistage press in which a plurality of rows of hot plates that can be opened and closed are arranged in parallel at equal intervals between left and right frames, each of the hot plates is Pinch rolls are located below and are supported vertically within the interval between each stage of hot plates when the press is opened, and engage with both sides of the lower part of the plate, which is in an almost upright state, to pinch and feed the plate. Since the plate to be processed is carried into the hot plate interval and the processed plate is carried out, the plate to be processed 2 and the processed plate 3 are placed with a bend 9,
Even if warpage or the like occurs, the board 2 to be processed is carried from the loader shelf 7 to the space between the hot plates 6, and the processed board 3 is transported to the hot plate 6.
This allows for smooth unloading from the storage space to the unloader shelf 8.

In addition, even if the thickness of the plate 2 to be processed increases beyond the initial setting due to a change in specifications, etc., the work can be done without having to widen the interval between the hot plates 6 of the horizontal multi-stage press 1.
This can be handled easily and effectively.

Furthermore, as described above, the forced drive for the plate 2 to be processed and the processed plate 3 is not by the locking force by the protrusions proposed earlier by the applicant, but by the pinch roll 38.
Because of the clamping and feeding force, damage to the plate is prevented, such as the lower part of the plate in an almost upright state being scraped off or scraped, and the generation of dust, cutting pieces, etc. is reduced. It has a certain effect.
