Description

  The present invention relates to a multistage cold press.

  Conventionally, a plywood / single plate laminate (LVL) or the like is manufactured by laminating and bonding a plurality of veneer veneers (hereinafter simply referred to as a veneer) through an appropriate adhesive. In the case of using a curable adhesive, for the purpose of adhering while maintaining the pressed state of the unbonded semi-finished product (hereinafter simply referred to as semi-finished product) for the time required for curing the adhesive. Or, for example, when a thermosetting adhesive is used, the adhesive applied to the required veneer and the adhesive facing the veneer to which the adhesive is applied are not applied. For the purpose of temporary bonding to improve the handling of semi-finished products in the subsequent hot-pressing process while promoting the familiarity (affinity) with the veneer and the adhesive throwing action on the veneer. As a press that presses semi-finished products at room temperature, the so-called cold press is used. However, the cold press currently widely used in this field is one of a pair of upper and lower pressure plates each having a pressure surface sufficient to cover a semi-finished product as disclosed in Patent Document 1, for example. The fixed pressure plate is the fixed pressure plate and the other is a movable pressure plate that can be moved up and down. A mechanism is attached, and the operating end of the operating mechanism is locked to the movable pressure plate. Through the operating mechanism, the movable pressure plate is intermittently separated and approached to the fixed pressure plate at appropriate times. Because it is a type that repeats loading and unloading (and unloading) of semi-finished products at the pressure processing place secured within the space between the pressure plates, that is, a single-stage cold press. There are inherent disadvantages as described below.

  That is, in order to improve productivity by using such a single-stage cold press, it is necessary to increase the total amount of semi-finished products that are pressed at each time at the pressing processing place. Even in actual plywood factories, semi-finished products are piled up to a height of about 1m to 1.5m (if necessary, a wooden platen for preventing load collapse is placed at intervals of about 30cm to 35cm. In this case, the adhesive applied to the veneer incorporated in the semi-finished product at an early stage is inevitably left until it is pressed. Since it gradually increases and curing proceeds gradually in an unpressed state, the compatibility with single plates to which no adhesive is applied and the anchoring effect on each single plate tend to gradually deteriorate, which is slow. Adhesive performance is lower than adhesive applied to veneers that are incorporated into semi-finished products It has inherent disadvantages easy and, sometimes, has become a Akuin to induce adverse effects such as insufficient adhesion-punk phenomenon.

  As a means for avoiding the disadvantages of the single-stage cold press, a relatively small amount of semi-finished products, which are divided into appropriate amounts, are individually conveyed to a plurality of pressing locations at appropriate times, and individually pressed. It is conceivable to use a multi-stage cold press having a function to perform the above. In this field, for example, a multi-stage press as disclosed in Patent Document 2 has been proposed. Discloses different types of multi-stage cold presses that can be used for different industries, but these known multi-stage presses all have weak points as described later. Therefore, the configuration was slightly unsuitable for practical use in this field.

Japanese Patent Publication No.54-28445 Japanese Patent Publication No.43-2180 Japanese Patent No. 3101849

  That is, the multistage press disclosed in Patent Document 2 is a plurality of single-stage presses stacked one above the other, and in addition to the liquid cylinder attached to the bottom fixed surface plate, Each of the appropriate number of intermediate surface plates located between the fixed platen and the uppermost fixed pressure plate is also provided with a liquid cylinder used for raising and lowering the movable pressure plate disposed above each intermediate platen. Therefore, as the required mode of the intermediate surface plate, sufficient rigidity is sufficient to accommodate the liquid cylinder and to hold the liquid cylinder so as to exert the required pressing force. Since a sturdy intermediate surface plate with a thickness (height) that can be guaranteed is required, the height of the press body becomes extremely high, as is apparent from the drawings of the publication, and of course, semi-finished products , Carry it to the pressing processing place of each stage, and carry it from the pressing processing place The loading / unloading mechanism used to do this also needs to be increased in accordance with the height of the press body. It has a weak point that operability, maintenance and manageability deteriorate.

  On the other hand, the multistage press disclosed in Patent Document 3 is a cold press used for removing distortion of a multilayer printed wiring board (hereinafter simply referred to as a board), and includes a lower elevator board provided with a hydraulic cylinder, An appropriate number of cooling plates having appropriate engaging means are provided between the upper pressing plate provided with the cylinder, and each cooling plate is engaged with the engaging means of each cooling plate to place each cooling plate at a predetermined position. A desired cooling plate is moved to a predetermined position by raising and lowering the lower lifting plate at appropriate times through the hydraulic cylinder, and via the engagement means. Then, a desired cooling plate is supported at a predetermined position, and the cooling plate located below the supported cooling plate is further lowered by a predetermined distance to thereby support the cooling plate supported at the predetermined position. In the space below Secure a processing place, carry in the substrate, then raise the cooling plate located below the supported cooling plate with a hydraulic cylinder, and if necessary, via the air cylinder In this case, the substrate is pressed and cooled by pressing the pressing plate downward. When the multi-stage cold press having such a configuration is used as a cold press for use in the field, As described later, efficiency is a weak point.

  That is, as is well known, the pressing force required for bonding of semi-finished products such as plywood / single plate laminate or temporary bonding is approximately 0.6 to 1 MPa (approximately 6 to 10 kgf / square 糎). Therefore, when the multi-stage cold press for different industries is diverted to a cold press used in this field, a relatively large capacity (hydraulic working surface is required) as a hydraulic cylinder to be attached to the elevator. In the case of using a large area and a plurality of hydraulic cylinders, it is necessary that the total working surface is a large area). In order to raise and lower all the appropriate number of cooling boards to a predetermined position, As for the lifting / lowering process length, a considerably long process length is necessary, and it is unavoidable that the equipment cost of the entire operation mechanism including the hydraulic pump for supplying oil to the hydraulic cylinder is expensive. No problem, but the problem is semi-finished at the bottom (or top) When the stage to be processed is switched from end to end so as to resume the pressing of the semi-finished product at the uppermost stage (or the lowermost stage) after the completion of the pressing, the large-capacity hydraulic cylinder Must be continuously lowered (or increased) over a long process length, and the period is substantially idle, so that the efficiency is higher than when the stages to be processed are switched one by one. It is a very bad point, for example, when the total number of press stages is relatively large, the required process length of the large capacity hydraulic cylinder becomes remarkably long, and the idle operation period is inevitably redundant. Conversely, if the total number of press stages is relatively small, the frequency of switching the stage to be processed from end to end will inevitably increase even if the required process length of a large capacity hydraulic cylinder is slightly short. Even so, weaknesses that reduce overall efficiency It made.

  The present invention was developed to eliminate the above-mentioned weak points of the multi-stage cold press. Specifically, the base of the press body is provided with a base for holding an operating mechanism for moving up and down the movable pressure clamp. In addition, the lowermost movable pressure clamping machine among an appropriate number of movable pressure clamping machines, which is disposed in a facing distance between the base and a fixed pressure clamping machine fixedly provided above the base. In addition, the multi-stage cold press is formed by locking the operating end of the operating mechanism, and at an appropriate number of two end surfaces parallel to each other on the uppermost movable pressure clamping machine, on the outside of the end surface. Protruding fixed stoppers, and appropriate shapes that can be advanced and retracted to positions corresponding to the fixed stopper mounting positions in the intermediate movable pressure clamping machines, excluding the uppermost and lowermost movable pressure clamping machines. Appropriate number of actuating members to attach and move each movable stopper and to move each movable stopper. Each of the stoppers is provided with an appropriate number of restricting members, such as hydraulic cylinders, which are disposed at appropriate positions and which can be moved up and down and have a restricting end portion which can be stopped for a while at a desired height. And a control mechanism for controlling the operation of the desired operation member and the operation of the regulating member in association with the operation of the operation mechanism. A cold press (claim 1) is proposed as a basic invention.

  2. The multi-stage type according to claim 1, further comprising stoppers respectively attached to at least one part of any one end face of each movable pressure clamping machine and at least two parts of the other end face parallel to the end face. A cold press (Claim 2) and a substantially sector-shaped movable stopper that can be reciprocally swiveled or intermittently rotated in the horizontal direction along a guide member provided on each movable pressure clamp. A multistage cold press according to item 2 (claim 3) and a flat plate-like movable stopper that can be reciprocated in the horizontal direction along the guide member provided in each movable pressure clamp. A multistage cold press according to claim 1 or claim 2 (claim 4) is proposed as a more practical invention.

  According to the multi-stage cold press according to the first aspect of the present invention, an appropriate number of movable pressure clamps can be obtained in a timely manner only through an operation mechanism in which an operation end is locked to the lowermost movable pressure clamp. Since the pressing force is applied, the height of the press body and the height of the entire pressing processing equipment including the loading / unloading mechanism are the same as those of the multistage press disclosed in the above-mentioned Patent Document 2. Thus, it does not become excessively high, and the equipment cost can be reduced, and the operability and maintenance management of the whole equipment can be facilitated. Based on this, the restriction member is operated in a timely manner (if necessary, the desired actuating member is operated to move the desired movable stopper into and out), and the desired movable pressure platen is moved to the desired position. By supporting it for a while, the location of the clamping process is secured below the desired movable clamping machine. Then, since the pressing process of the semi-finished product is performed, the operation process length required for the operation of the operation mechanism is only required for at most one stage, even when switching any stage. Even when the stages to be processed are switched from end to end, it is not necessary to lengthen the operation process length of a large-capacity hydraulic cylinder or the like regardless of the total number of press stages. This multi-stage press is more efficient and practical than the case of diverting it to other uses.

  Thus, as the number of locations where each stopper is provided, one location of any one end face of each movable pressure clamping machine and two locations of the other end face parallel to the end face are determined by the movable pressure clamping machine. Although it is mentioned as the minimum necessary number of places suitable for ensuring stable support, as disclosed in claim 2, if necessary, an appropriate number can be increased, for example, the area of one tatami mat. In the case of a movable pressing machine that presses a semi-finished product having a surface exceeding 50 mm, it is practical to attach two parts each (preferably near the corners of the end face) to two parallel end faces. is there. In addition, various forms of the movable stopper are assumed, but for example, a substantially fan shape as disclosed in claim 3 or a flat plate shape as disclosed in claim 4 is representative. As a typical form.

  Reference numeral 5A denotes a tongue-shaped fixing stopper, which protrudes from the corners of the left and right end surfaces of the uppermost movable pressure clamp 4D, one by one (for convenience), and is a regulating member to be described later When the restriction end portion 8a comes into contact, a position where the uppermost movable pressure clamping machine 4D should stop for a while is determined.

  Reference numeral 5 denotes a substantially fan-shaped movable stopper, which conforms to the attachment position of the fixed stopper 5A in the intermediate movable pressure clamps 4B and 4C, excluding the uppermost and lowermost movable pressure clamps 4A and 4D. One position at a time (four at each stage) is reciprocated in the horizontal direction along the guide member 4a having a U-shaped cross section, as illustrated in FIGS. It is attached so as to be able to turn (or intermittently rotate), and is normally immersed (stored) inside the guide member 4a as illustrated in FIG. As shown in FIG. 3 (b), the operation of the operation member 6 based on the above control is advanced to the outside of the guide member 4a and the restriction end 8a of the later-described restriction member comes into contact. In this case, a position where the intermediate movable clamping machine 4B (or 4C) should stop for a while is determined.

  Reference numeral 6 denotes an actuating member composed of a servo motor, a rotary cylinder, etc., and is attached to each of the substantially fan-shaped movable stoppers 5 (for convenience, four at each stage). Based on this control, as shown in FIGS. 3A and 3B, the substantially fan-shaped movable stopper 5 is reciprocated in the horizontal direction (or intermittently rotated).

  Reference numeral 7 denotes an operating mechanism including a pair of left and right hydraulic cylinders, and the operating end is locked to the lowermost movable pressure clamping plate 4A via the locking tool 4, and a control mechanism 9 which will be described later.

The position where any desired movable pressure clamping machines 4B, 4C, and 4D should be stopped for a while is determined.

Reference numeral 9 denotes a control mechanism that controls the operation of the operating member 6, the operating mechanism 7, and the restricting member 8 to raise and lower the movable pressure clamps 4A, 4B, 4C, and 4D as desired.
In addition, since various aspects are mentioned about the detailed control aspect of a control mechanism, it is explained in full detail anew later, in order to demonstrate the operation | movement aspect of the whole processing equipment.

  Reference numerals 11 and 12 are examples of auxiliary equipment attached to the press body as necessary, and are a carry-in mechanism and a carry-out mechanism composed of a table lifter and the like. The carry-in mechanism is provided on the front side of the press, and the back side of the press. FIG. 4 shows a mode in which each of the unloading mechanisms is provided, for example, by operating switches (not shown) based on the operator's eye measurements, or although not shown, the control mechanism 9 uses the movable pressure clamping machine 4A. By control related to the raising / lowering of 4B, 4C, and 4D, it raises / lowers up and down timely, and assists in carrying in the semi-finished product 10 to the press main body and carrying out the processed semi-finished product 10a.

  The multi-stage cold press according to the present invention is configured, for example, as described above, and a specific operation mode will be described in detail below together with an example of a control mode of the control mechanism 9. 5 to 14 illustrate the operation modes illustrated in FIGS. 5 to 14, in which the semi-finished products are carried in order from the uppermost stage to the lowermost stage. This is an example of repeatedly carrying in (and carrying out) a semi-finished product.

  That is, initially, when the semi-finished product 10 is carried onto the movable pressure disc 4D, as shown in FIG. The operation of the actuating member 6 and the regulating member 8 is controlled by the control mechanism 9 so that the regulating end 8a is located at the lowermost part, and the interval h between the fixed pressure clamping machine 2 and the movable pressure clamping machine 4D is half The operation of the operation mechanism 7 is controlled by the control mechanism 9 so as to raise the movable pressure clamping machine 4D together with the movable pressure clamping machines 4A, 4B, and 4C until reaching a size suitable for carrying in the product 10.

  In addition, by adjusting the height of the carry-in mechanism 11 on which the semi-finished product 10 is previously placed so as to be suitable for carrying in the semi-finished product 10, the semi-finished product 10 is moved in the direction of the arrow shown in the drawing, The semi-finished product 10 is carried onto the movable pressure clamping machine 4D, and then the movable pressure clamping machine 4D is clamped together with the movable pressure clamping machines 4A, 4B, and 4C as illustrated in FIG. The operation of the operating mechanism 7 is controlled by the control mechanism 9 so as to be raised to a height suitable for the semi-finished product 10, and a pressing action is applied to the semi-finished product 10.

Next, when the semi-finished product 10 is carried onto the movable pressure clamping machine 4C, as shown in FIG. 7, the regulation end 8a of the regulation member is fixed to the fixed stopper 5A attached to the movable pressure clamping machine 4D. The operation of the restricting member 8 is controlled by the control mechanism 9 until it reaches the height at which it is in contact with the movable member, and the movable pressure platen 4D is supported at the illustrated position for a while, and the movable pressure platen 4D and the movable pressure platen are supported. The operation of the operating mechanism 7 is controlled by the control mechanism 9 so that the movable pressure clamping machine 4C is lowered together with the movable pressure clamping machines 4A and 4B until the distance h of 4C reaches a size suitable for carrying in the semi-finished product 10. Control by.
The regulating force necessary for the regulating member 8 is the total weight (the total weight (the sum of the weight of the movable pressure clamping machine 4D for regulating the position) and the weight of the semi-finished product 10 mounted on the movable clamping machine 4D). Ultimately, it should be sufficient to support for a while the total weight of the movable pressure clamping machines 4C and 4B and the weight of the semi-finished product 10 mounted on the movable pressure clamping machines 4C and 4B. Needless to say, it does not require a sufficient regulating force to give a required pressing action to the semi-finished product 10.
Further, regarding the restriction position of the movable pressure clamp 4D by the restriction end portion 8a of the restriction member (and the restriction position of the movable pressure clamps 4C and 4B in the subsequent processing steps), as shown in the drawing, The semi-finished product 10 placed on the clamp 4D is not limited to the position where the semi-finished product 10 contacts the fixed pressure clamp 2 and is not shown in the figure. Even if it is a position where a slight gap is formed between the fixed pressing machine 2 and the fixed pressing machine 2, there is no practical problem.

At the same time, the semi-finished product 10 to be carried in next is replenished to the carry-in mechanism 11, the height of the carry-in mechanism 11 is adjusted, and the semi-finished product 10 is moved in the direction of the arrow shown in the figure. Then, the semi-finished product 10 is carried on the movable pressure clamping machine 4C, and then the movable pressure clamping machine 4C is clamped together with the movable pressure clamping machines 4A and 4B as shown in FIG. The operation of the operating mechanism 7 is controlled by the control mechanism 9 so as to be raised to a height suitable for the semi-finished product 10, and a pressing action is applied to the semi-finished product 10.
In addition, regarding the control of the regulating member 8 by the control mechanism 9 after the pressing action is applied to the semi-finished product 10, as shown in FIG. 8, the regulating end 8a of the regulating member is lowered to the lowest position each time. Control can be used, but when it is necessary to raise again in the next process, the operation of the movable stopper 5 to be operated in the next process is not hindered as in another control mode described later. It is possible to adopt a configuration in which the operation of the regulating member 8 is controlled by the control mechanism 9 so that the regulating end 8a of the regulating member is in a standby state at the intermediate position.

  Next, when the semi-finished product 10 is carried onto the movable pressure clamp 4B, as shown in FIG. 9, all the movable stoppers 5 attached to the movable pressure clamp 4C are set to the advanced state. In addition, the operation of the operation member 6 is controlled by the control mechanism 9 and the restriction end 8a of the restriction member 8 reaches the height at which it comes into contact with the movable stopper 5 where the movable pressure clamp 4C has advanced. By controlling the operation by the control mechanism 9, the movable pressure clamping machine 4 </ b> C is supported for a while at the position shown in the figure, and the distance h between the movable pressure clamping machine 4 </ b> C and the movable pressure clamping machine 4 </ b> B is The operation of the operation mechanism 7 is controlled by the control mechanism 9 so as to lower the movable pressure clamp 4B together with the movable pressure clamp 4A until reaching a size suitable for carrying in.

At the same time, the semi-finished product 10 to be carried in next is replenished to the carry-in mechanism 11, the height of the carry-in mechanism 11 is adjusted, and the semi-finished product 10 is moved in the direction of the arrow shown in the figure. Thus, the semi-finished product 10 is carried onto the movable pressure clamping machine 4B, and then the movable pressure clamping machine 4B is suitable for pressing the semi-finished product 10 together with the movable pressure clamping machine 4A as illustrated in FIG. The operation of the operation mechanism 7 is controlled by the control mechanism 9 so as to rise to the height, and a pressing action is applied to the semi-finished product 10.
The restricting member 8 is once controlled by the control mechanism 9 so that the restricting end 8a is lowered to the lowest position and the support of the movable pressure clamp 4C with respect to the movable stopper 5 is released. The movable stopper 5 of the panel 4C controls the operation of the operating member 6 by the control mechanism 9 so that the movable stopper 5 returns to the initial immersion state at an appropriate time.

  Next, when the semi-finished product 10 is carried onto the movable pressure clamp 4A, as shown in FIG. 11, all of the movable stoppers 5 attached to the movable pressure clamp 4B enter the advanced state. In addition, the operation of the operation member 6 is controlled by the control mechanism 9 and the restriction end 8a of the restriction member 8 reaches a height at which the restriction end 8a contacts the movable stopper 5 where the movable pressure clamp 4B has advanced. By controlling the operation by the control mechanism 9, the movable pressure clamping machine 4B is supported for a while at the illustrated position, and the distance h between the movable pressure clamping machine 4B and the movable pressure clamping machine 4A is set to The operation of the operation mechanism 7 is controlled by the control mechanism 9 so as to lower the movable pressure clamp 4A until reaching a size suitable for carrying in.

At the same time, the semi-finished product 10 to be carried in next is replenished to the carry-in mechanism 11, the height of the carry-in mechanism 11 is adjusted, and the semi-finished product 10 is moved in the direction of the arrow shown in the figure. Thus, the semi-finished product 10 is carried onto the movable pressure clamping machine 4A, and then the movable pressure clamping machine 4A is raised to a height suitable for the clamping of the semi-finished product 10 as illustrated in FIG. The operation of the operation mechanism 7 is controlled by the control mechanism 9 to apply a pressing action to the semi-finished product 10.
The restricting member 8 is controlled by the control mechanism 9 so that the restricting end 8a is lowered to the lowest position and the support of the movable pressure clamp 4B to the movable stopper 5 is released. The movable stopper 5 of the panel 4B controls the operation of the operation member 6 by the control mechanism 9 so that the movable stopper 5 returns to the initial immersion state at an appropriate time.

  Thus, when the required pressing time for the semi-finished product 10 carried on the movable pressing machine 4D has elapsed, as illustrated in FIG. 13, the interval h between the fixed pressing machine 2 and the movable pressing machine 4D is The operation of the operating mechanism 7 is controlled by the control mechanism 9 so as to lower the movable pressure clamping machine 4D together with the movable pressure clamping machines 4A, 4B, and 4C until it reaches a size suitable for carrying out (carrying in) the semi-finished product 10. By controlling and adjusting the height of the carry-out mechanism 12 at an appropriate time, by moving the pressed semi-finished product 10a (in the case of normal temperature bonding, it becomes a bonded semi-finished product) in the direction of the arrow, The semi-finished product 10a that has been pressed is carried out from above the movable pressure platen 4D onto the carry-out mechanism 12.

  At the same time, the semi-finished product 10 to be carried in next is replenished to the carry-in mechanism 11, the height of the carry-in mechanism 11 is adjusted, and the semi-finished product 10 is moved in the direction of the arrow shown in the figure. Then, the semi-finished product 10 is carried onto the movable pressure clamping machine 4D, and then, as illustrated in FIG. 14, the movable pressure clamping machine 4D is moved together with the movable pressure clamping machines 4A, 4B, and 4C. The operation of the operating mechanism 7 is controlled by the control mechanism 9 so as to be raised to a height suitable for pressing, and a pressing action is applied to the semi-finished product 10.

Next, when the required pressing time for the semi-finished product 10 carried on the movable pressure clamping machine 4C has elapsed, the regulating end 8a of the regulating member is attached to the movable pressure clamping machine 4D as illustrated in FIG. The operation of the restricting member 8 is controlled by the control mechanism 9 until it reaches the height at which it comes into contact with the fixed stopper 5A, and the movable pressure clamping machine 4D is supported at the illustrated position for a while and movable with the movable pressure clamping machine 4D. The operating mechanism 7 is moved so that the movable pressure clamping machine 4C is lowered together with the movable pressure clamping machines 4A and 4B until the distance h between the pressure clamping machines 4C reaches a dimension suitable for carrying out (carrying in) the semi-finished product 10. The operation is controlled by the control mechanism 9, and the height of the unloading mechanism 12 is adjusted at an appropriate time, and the pressed semi-finished product 10a is moved in the direction of the arrow in the drawing, thereby From above, onto the carry-out mechanism 12, the pressed semi-finished product 10 At the same time, the semi-finished product 10 to be carried in next is replenished to the carry-in mechanism 11, the height of the carry-in mechanism 11 is adjusted, and the semi-finished product 10 is moved in the direction of the arrow shown in the figure. Thus, the semi-finished product 10 is carried onto the movable pressure clamping machine 4C, and then the movable pressure clamping machine 4C is moved together with the movable pressure clamping machines 4A and 4B as shown in FIG. The operation of the operating mechanism 7 is controlled by the control mechanism 9 so as to be raised to a height suitable for pressing, and a pressing action is applied to the semi-finished product 10.
Regarding the regulating member 8, after the movable pressure clamping machine 4C is lifted to a height suitable for the clamping of the semi-finished product 10 together with the movable pressure clamping machines 4A and 4B, the regulation end 8a is once set. Is controlled by the control mechanism 9 so that the support to the fixed stopper 5A of the movable pressure clamp 4D is released.

Next, when the required pressing time for the semi-finished product 10 carried on the movable pressing machine 4B has elapsed, as shown in FIG. 17, all the movable stoppers 5 attached to the movable pressing machine 4C are in the advanced state. The operation of the actuating member 6 is controlled by the control mechanism 9 so that the regulating member 8 reaches the height at which the regulating end 8a of the regulating member comes into contact with the movable stopper 5 of the movable pressure clamp 4C. Is controlled by the control mechanism 9 so that the movable pressure clamping machine 4C is supported for a while at the position shown in the drawing, and the distance h between the movable pressure clamping machine 4C and the movable pressure clamping machine 4B is set to the semi-finished product 10. The operation of the operation mechanism 7 is controlled by the control mechanism 9 so as to lower the movable pressure clamping machine 4B together with the movable pressure clamping machine 4A until reaching a size suitable for unloading (carrying in). Adjust the height of the carry-out mechanism 12 at the appropriate time. By moving the pressed semi-finished product 10a in the direction of the arrow, the pressed semi-finished product 10a is carried out onto the carry-out mechanism 12 from the movable pressure clamping plate 4B, and at an appropriate time. Then, after the semi-finished product 10 to be loaded next is replenished to the carry-in mechanism 11, the height of the carry-in mechanism 11 is adjusted, and the semi-finished product 10 is moved in the direction of the arrow in the drawing, thereby The semi-finished product 10 is carried in, and then, although not shown in the drawing, together with the movable pressure clamping machine 4A, the movable pressure clamping machine 4B is raised to a height suitable for the clamping of the semi-finished product 10.

The operation of the operation member 6 is controlled by the control mechanism 9 so that the movable stopper 5 of the movable pressure clamp 4C is returned to the original immersion state at an appropriate time.

  In the following, by repeating the same operation, it is possible to carry in (save out) the semi-finished products sequentially from the uppermost movable pressure clamping machine to the lowermost movable pressure clamping machine. Only the operating mechanism with the operating end locked to the pressing machine is used to apply pressing force to the appropriate number of movable pressing machines in a timely manner, so that the height of the press body and the loading / unloading mechanism The overall height of the pressing processing equipment, including the above, is not excessively high as in the multistage press disclosed in the above-mentioned Patent Document 2, and the equipment cost is reduced and the operability of the whole equipment is improved.・ As well as ease of maintenance management, as is clear from the illustrated embodiment, when switching the stage to be processed, the regulating member is operated in a timely manner based on the control of the control mechanism (necessary) Depending on the condition, the desired actuating member is operated and the desired movable stopper is advanced.・ Immerse) and support the desired movable pressure clamping machine at the desired position for a while, so that a clamping processing place is secured below the desired movable pressure clamping machine and the semi-finished product is pressed. Therefore, in any case of switching between the stages, the operation process length required for the operation of the operation mechanism is at most one stage (except for the initial start-up, the semi-finished product) A very short process length is sufficient to ensure a gap suitable for unloading and loading (see FIGS. 13 to 17). Even if the stages to be processed are switched from end to end, regardless of the total number of stages in the press, Since it is not necessary to lengthen the operation process length of a large-capacity hydraulic cylinder or the like, it is more efficient than the case where the multistage press disclosed in the above-mentioned Patent Document 3 is diverted to other uses. It is excellent in practicality since it can be processed easily.

  Thus, the number of locations where each of the stoppers is provided is that one of the end faces of each movable pressure clamping machine and two places on the other end face parallel to the end face are movable pressure clamping machines. The minimum number of places suitable for securing stable support is listed, but if necessary, an appropriate number can be increased, for example, a semi-finished product with a surface exceeding the size of one tatami mat. In the case of a movable pressing machine to be pressed, it is practical to attach two each to two parallel end faces as shown in the illustrated embodiment.

If necessary, the shape / attachment position of the fixed stopper attached to the uppermost movable pressure clamping machine, or the arrangement position of the restricting member (and the support base), corresponding to the form / attachment position of the movable stopper, etc. However, in any case, the form of the movable stopper is not limited to the illustrated substantially fan-shaped or flat-plate shape. It is enough to support the lathe for a while A Jo, so as not to inhibit the operation of the regulating end portion of the regulating member, sufficient if provided so as to be advanced and absorption.

Further, the operation of the regulating member 8 is controlled by the control mechanism 9.

  Next, when a required pressing time for the semi-finished product 10 carried on the movable pressure clamping machine 4B has elapsed, as shown in FIG. 29, all the movable stoppers 5 of the movable pressure clamping machine 4C enter the advanced state. Further, the operation of the operating member 6 is controlled by the control mechanism 9, and the regulating end 8a of the regulating member is brought into contact with the movable stopper 5 of the movable pressure clamping machine 4C so that the movable pressure clamping machine 4C is brought into the illustrated position.

  Hereinafter, by repeating the same operation, it is possible to carry in and out semi-finished products in order from the lowermost movable pressure clamping machine to the uppermost movable pressure clamping machine. Even in the case of carrying out unloading and loading of the semi-finished product with respect to any stage of the movable pressure clamping machine, as in the case of the control mode, except at the time of initial start-up, The length of the operation process required for the operation mechanism is not limited to the total number of stages in the press, and a very short process length is sufficient to ensure a gap suitable for unloading and loading a half-finished product. It is beneficial that the pressing process can be repeated. Furthermore, although not necessarily actively recommended, if necessary, the control mechanism also has a manual operation function, and is manually operated by an operator each time without any fixed order. It is not impossible to adopt a control mode for carrying out and carrying in a semi-finished product with respect to the movable movable clamping plate of the stage, and there is no particular restriction on the control mode of the control mechanism.

As the operating mechanism and the restricting member, a hydraulic cylinder is used because it is easy to stop the operation for a while at a desired position in the operation process. Although not shown in the figure, it is convenient because it can be very easily adapted to carry in, press and carry out semi-finished products even when the thickness of semi-finished products is changed as necessary. .
However, it is not necessarily limited to the hydraulic cylinder, and as described above, except for the initial start-up, even when carrying out unloading / loading of the semi-finished product with respect to any stage of the movable pressure clamping machine, The length of the operation process required for the operation mechanism is extremely short, so that, for example, a known screw mechanism composed of a combination of a male screw and a female screw has no practical problem and a restriction member is also necessary. Depending on the situation, the semi-finished product can be preliminarily prepared by changing the position of the regulating end to the vicinity of the required position in the next process at an appropriate time, such as during clamping of the semi-finished product. Since the length of the operation process necessary for the actual unloading / carrying in can be shortened, even with a known screw mechanism, there is no particular problem in practical use, the shape of the regulated end, or the location of the regulated end, etc. Since there are no special restrictions, Regardless of the shape and location (upper end), for example, by obtaining the action of the screw by the male screw member, the control end is projected on the side of the female screw member that moves up and down along the guide member. It can be changed.

  Further, the form of each movable pressure clamp is not limited to a simple flat plate shape as shown in the illustrated embodiment, and is not shown. However, if necessary, each movable pressure clamp is disclosed in Patent Document 1. Or other known roll conveyors, belt conveyors, etc. (if necessary, attachable to the pressing surface of each movable pressing machine). It is possible to adopt a structure that makes it easy to move and load semi-products in and out (or semi-automatic), and is similar to the loading mechanism and unloading mechanism. It is possible to automate (or semi-automate) the entire processing process by adopting a configuration in which conveyors are provided.

  Further, in the embodiment, the width of the base and the fixed pressing machine with respect to the longitudinal direction of each pressing machine is set wide, the longitudinal direction side is set to the front (and the back), and the vertical machine frame is set to the side. The semi-finished product is loaded and unloaded in the direction perpendicular to the longitudinal direction of each pressing machine, but if necessary, contrary to the illustrated example, The width of the base and the fixed pressure clamping machine with respect to the longitudinal direction and the direction perpendicular to the longitudinal direction is set wide, and a vertical machine frame and the like are arranged on the longitudinal direction side so that the semi-finished product is in the same direction as the longitudinal direction of each pressure clamping machine. There is no problem even if the design is changed to a type that carries in and out, and there is no problem if the design is changed to increase or decrease the number of movable pressure clamps as required.

  In the above embodiment, only the semi-finished product is carried into each stage of the press and pressed, and if necessary, the semi-finished product is placed on a floor plate having an appropriate width. In addition, it is also possible to adopt a processing mode in which the semi-finished product is carried into each stage of the press together with the floor plate. Further, for example, in the case where a semi-finished product having a relatively small number of layers is to be processed, It is possible to adopt a processing mode in which a small number of semi-finished products are made into one set and each set is carried into each stage of the press.

  As is apparent from the above, the multi-stage cold press according to the present invention can reduce the equipment cost and facilitate the operability and maintenance management of the entire equipment as compared with the known multi-stage cold press. Compared with the case where the multi-stage cold press of different industries disclosed in Patent Document 3 is diverted to a multi-stage cold press for this industry, the semi-finished product can be pressed more efficiently. There are advantages, and the effect of implementing the present invention in this field is remarkable.
