Description

Detailed Description of the Invention

[0001]

[Industrial application] The panel bending machine is a thin plate (Ch
apa) bending machine, in particular, for forming metal panels (for office and industrial metal furniture, home appliances, etc.) by weaving the periphery of a thin plate.

This panel machine can reach higher production levels by specializing in production. Then, one of these panels is manufactured as a thin plate having a thickness of 3 mm in a more concrete manner in a wide range of dimensions and shapes. This allows production to be more advanced (for this product) than previous folding machines. On the other hand, this latest one has the ability to manufacture a wide variety of products and can accommodate most sheet thicknesses.

A feature of the panel manufacturing machine is that the thin plate to be bent is two jaws (M) of a vise (Mordaza).
sandwiched by the anddibulas). The vise determines the fold line along one of the vertical edges and is closed. In addition, one of the jaws is usually on the upper side and the rolling mill (Pisado)
r), which moves vertically due to the cylinders installed between the fixed framework of the machine and the body supporting the rolling mill, typically a double cola de milan.
The gears inserted in o) move to connect to the support body and the rolling mill. On the other hand, the other jaw, which is generally the lower jaw, is fixed and is called by the name of the nail holder. This normal arrangement is for rolling mills and
The specific relative position of the tralama) should be considered even if it does not affect the essence of the invention.

On the other hand, recent thin plate folding machines have associated operating means. That is, it is an operation facility for supplying a thin plate for bending and disposing the thin plate at an accurate position where it can be bent.

This operating facility not only replaces some actions that had to be performed manually by the operator until now, but also by the connection with a central control computer in combination with a numerical control device CNC. , Automatically, based on a sufficient information program, it is possible to realize the continuous operation of the forward movement, the backward movement, and the rotation of the thin plate necessary for performing the specific work of bending.

Among the presently claimed objects of the invention, a manipulator designed according to the new concept of rolling means and rolling action of sheet metal, as well as means for determining and controlling the length position and angle of the sheet metal, is a central control. Connected with computer, bring more accurate, reliable, active and efficient operation.

Regarding the implementation of folding, essentially one of the folding machines is a rolling mill stand, a receiver.
a) That is, it is a set of nail holders, in which the thin plate is fixed, and at the inner edge of the thin plate, a fold line is marked on the edge of the edge or the decorative portion, where the upper bending claw bends the lower part of the thin plate. Perform the upper folding process with the lower folding claws.

In particular, one of the improvements of the invention is that the structure of the folding machine can be moved independently and integrated into a more sophisticated production system, and its special purpose is tangential. Folding has become possible with regard to bending angle, thin plate thickness, and complicated folding due to its extremely high operating efficiency and high versatility.

When integrated into a high-level production system, the folding machine has the sheet feeding assisting means and the automatic placing means installed on the workbench, and is properly fixed by the rolling mill-receiver set.

2. Description of the Related Art In order to manufacture a panel, continuous operation by a panel manufacturing machine captures a sheet material, and then bends all or part of each side of the sheet according to the intended panel. Except for the case of the first two parallel side folds of sheet metal, the continuous folds of the remaining sides (fold all sides, considering the more usual case) are the active lengths of the rolling mill. Is desired to be applied exactly to the length to be folded. If the rolling mill were longer than the side it was supposed to fold, this fold would be blocked by an edge that was already folded on the adjacent side. If the rolling mill is shorter than the side surface, the fold lines defined by it will not reach all the planned fold lines, and the folds will go out of the limit frame surrounded by the rolling mill. Let's do it.

In the usual case, each side of the sheet material is provided with a second crease which creates an edge parallel to the panel surface,
It is necessary that the working edge of the rolling mill be lowered into the shape of a labio so that it enters under the edge during the panel forming process. Therefore, the lips must also extend to each end of the rolling mill.

Along with these aspects, the known weaving and bending machine (Salva
gnini Transferica S. p. Company A's European Patent EP 0274159 and Maru Kik
ai Kogyo Co. European patent EP01
5091). It is equipped with a rolling mill, which is based in the central part and has an adjusting mechanism, each end part being composed in particular of two adjacent (longitudinal and lateral) lip-shaped sides, and sometimes also of longitudinal replenishment. There is also a middle part for. In this way, the minimum operating length of the rolling mill is the central part plus 2
The combined length of the two end portions can be secured by adding the intermediate replenishment portion.

In order to obtain the correct dimension (above the minimum) with this system, it takes a lot of work, the time to retract the auxiliary part, the size of the substitute and the panel material to match the required length. Efforts need to be made to adapt to the process and even to perform the process inside the panel. This is because the required dimensions are diverse, so it is necessary to replenish various dimensions, and accurate calculation for required replenishment (combination of replenishment parts) and operation to alternate auxiliary parts with each other. There will be a delay in production.
This delay diminishes the benefits of automation offered by other machinery of the machine and computer management.

To date, the only excuse for this problem has been to prepare for the automation of costly and complex auxiliary parts. In the end, the only excuse that follows is to seek enough auxiliary parts, but one needs to consider the calculation of sufficient combinations and the slow and expensive replacement work. Thus, it has been found that efforts made in designing highly specialized and automated machines to maximize productivity are futile.

On the other hand, with respect to the thin-plate manipulator-feeder, its general structure consists of a pedestal that moves in two directions.
One direction is the longitudinal direction, which intersects at right angles to the vertical plane created by the machine tool for the fold. This movable pedestal provides a wide garage for thin sheet passages.
and has a vise composed of upper and lower half vises. As a result, the thin plate is held on the horizontal surface of the work table, and the bending work of the thin plate is performed vertically.

Then, by making a rotation and moving vertically, the thin plate is secured in its proper working position. Similarly, check for a secure fixation during the folding process. The movement of the lamellas in the lateral direction is not intended to always carry out the same operation and to be originally fixed so that the lamellas are fed to the vertical surface of the workbench. The means will be considered further down.

For a vise jaw, see (Sarlvgni
ni Transfereria S. p. Company A's Italian patent P-1086365) is known, but the lower half vise surface lies in the same plane as the working horizontal plane and rotates. On the other hand, the upper half vise has a gyro loco device which vertically captures and releases the thin plate and is rotated by the lower half vise through the trapping pressure of the thin plate. In this method, the vise set envisions that thin plate capture should be performed, and that longitudinal and angular pulling movements are continued. It has a relatively small holding surface area to the plane of the lamellae, and in particular in the case of angular tension, it has a relative gliding between the vise and the lamellae. Automatic position measurement with this system is done with respect to the vertical axis of the vise. This gliding causes a discrepancy between the theoretical dimensional position and the actual position. The folding device is then stopped, resulting in excessive fold edges and lack of width, and its width changes in the case of sliding with relative angles.

From another point of view, the exact position of the lamella is very important for obtaining accurate results,
Accuracy is required to determine the initial position of the sheet as it is fed onto the workbench and as before it was clamped by the vise.

In this respect, the supply of lamellas is such that the lamellas are placed between three mechanical braking devices installed on the workbench, and the geometric center of which is that of the movable pedestal, e.g. When in a confirmed position, such as at the rear end of the stroke (or farther away from the crease plane), it is in the vertical line of the vise axis of movement. This position will be adopted as the first position for later positions in order to carry out the work in succession. Sometimes the final precise position defined by this system depends directly on the precision made to the geometric center. This exact content cannot be guaranteed in practice due to the unique difficulty of determining the axes that belong to the moving system independent of the geometrical position. Therefore, the geometric center position of the lamella will occupy its theoretically ideal position with these three mechanical brakes. Also, the position error with respect to these three mechanical brakes that is likely to occur is not for proof purposes. This causes the edges of the lamella to move relative to the theoretical position based on the theoretical center. And this will coincide with the vertical plane of the fold. Therefore, all performed creases will result in being affected by this discrepancy, resulting in more or less defective decisions for the width of the edges or the fold edges.

For the various steps of the fold, the tangential fold reduces wear between the fold claw and the sheet, which results in a high quality, non-grooved sheet. It is suitable for bending thin sheets before painting.

Machines known for this process (Sa
lvgnini Transferica S. p.
In European patent EP 0274159) of company A, there are two folding pawls, an upper pawl (for downward folding) and a lower pawl (for upward folding), which are of a single-part abutment. It is installed at each edge of the cross section at "C". It has up-and-down motion by a vertical hydraulic cylinder and has only one rear axle. The first problem with such an arrangement is that the tangent conditions are insufficient during folding (same axis for two pawls in a firm support) resulting in a right angle (90 °) weave. Much of what is done, including bending, needs to be coupled with movements of tangential fold rotation angles, especially referred to, to correct dimensional differences due to insufficient tangents with increasing radius of gyration. Come on. This correction applies to work intensity rather than when spinning. That is, in addition to the functional complexity of this, continuous operation is required, and as a direct result, the production rhythm is reduced. Another problem with this construction is that it occurs when the two pawls of a vertical cylinder folding machine are in operation and they have to be enlarged to work. This operation has worse consequences than when pressure is applied when one of the two pawls is activated and when the other pawl is activated. This is due to the scale of the cylinder
For o), the function of further expansion work is forced.

In another arrangement, the rolling mill is known to be connected to the rear. This is a stroke in which the movable edge operates in an arch shape. This is not absolutely essential for folding, as the complete folding process will carry out additional longitudinal movements on the sheet.

Rather, the only way to correct the equipment configuration in the direction of the arc-shaped rolling stroke of the rolling mill is to change the position of the strips according to the crease line and the height of the fold edge. You have to secure it when you pull it back.

[0024]

The proposed improvement, on the one hand, is, on the one hand, a rolling mill without the need for peripheral auxiliary parts and with the ability to make an exact determination of the length of the rolling mill required at each point in time. It provides automatic vertical adjustment.

According to the present invention, the rolling mill has a structure in which each end portion is attached to the central portion by appropriately inserting the intermediate auxiliary portion. Also specially, between the central part and each end section, and by a combination of appropriately assisted auxiliary parts, at least by means of a package of single parts of reduced thickness, and for determining the play of each single part. There is a stretchable part constituted by a spacing stretcher inserted between the auxiliary parts, by external means for creating oppositional movement of the spacer and by means of limiting the maximum play between these single parts. .

In fact, with this new construction of the rolling mill, maximum pressure conditions and secant elastic
The difference that exists between the maximum loosening states of a) is the working length. This would be sufficient if a simple replacement of the auxiliary part in changing the dimensions of the rolling mill is achieved to the desired length, but not an exact approximation, and further based on the auxiliary part's dimensional function. Fine adjustments to be accurate will suffice.

Certainly, in order to adjust the size of the variability of the stretchable portion, the auxiliary portion (seccion co
Replacing the mplntaria) alone may not be appropriate, and likewise, repeating the stretchable portion cannot at all produce the effect required to replace the auxiliary portion.

To date, the concept of high quality finishing of the folds in the panel has been such that the rolling mill has been adjusted to perform continuously throughout its length, so that the problem of length adjustment is It was inseparable from the fact that a complex combination of parts and operations had to be solved. Mathematically new concept of rolling mill was created by telescopic vertical adjustment, and non-contiguous or otherwise interrupted surface support of edges interrupted by play between individual parts, a technique for solving length adjustment problem However, to date, the notion of the need for continuous surface rolling mills has not worked at all.

Therefore, in addition to the theoretical development of the product,
The actual experiment of the product content was advanced in the manufacturing process.
For that purpose, a controlled inspection of the folded panels was carried out using the classical method of quality inspection. Basically, the quality control method of the edge is by palpation and visual inspection. For some products, palpation is more accurate than just visual inspection, and regarding visual inspection for edge defects, quality control by palpation is done by eye with a smooth paint finish. Required depending on the case of inspection.

On the basis of these assumptions, bending tests of thin plates of various qualities and various thicknesses were conducted, and excellent results as described below were obtained.

One of the qualities of the thin plate tested is 40 kg per square millimeter, and an iron plate having a thickness of 0.5, 1, 1.5, or 2 mm is provided with a play of 0.5 in the stretchable portion. And 1 mm, the final product of the panel is unpainted and painted.

All subsequent palpation and visual inspections show the correct quality of the folds, no defects, and edge finish with a continuous surface (superficie).
Continua) indistinguishable from what was caught using the rolling mill.

The quality of another experimental thin plate is a stainless thin plate, 304 of AISI standard, and a thickness of 0.5,
1.5 mm, single play between the stretchable parts is 0.5 and 1 mm. Similarly, a palpation test and a visual inspection gave an indication of the correct quality of the fold compared to the fold made by the continuous surface mill.

From what has been shown so far, the special construction of the telescoping part gives a simple and efficient solution to the longitudinal adjustment problem of the rolling mill, and in addition to its quality level (separate various mounting parts The traditional continuous edge rolling mill did what it could while maintaining quality standards. Furthermore, it was shown that the concept that the movable edge of the rolling mill had to be continuous could be broken.

Although the invention has the greatest general versatility, in essence, two attached telescoping sections are attached to each side of the central section and each has a 9 mm longitudinal variable capability. . This adjusts the perimeter so that one of the possible combinations of auxiliary parts can be rapidly determined in the longitudinal variables of the stretch part. As a result, the vertical adjustment operation can be substantially simplified, and the necessity of storage of these elastic portions, storage means and automatic transportation can be remarkably saved. In many cases, it is possible to dispense with the need to replace the auxiliary part.

Although the solution as shown here has been very advantageous so far, it has not been absolutely effective. Because (it is taken over by the fine adjustment of the stretchable part)
In order to insert the auxiliary part needed for a rough adjustment, it is necessary to determine a non-automated substitute of the auxiliary part and maintain its inventory. Of course, now they are the same. After all, there are enough simple parts (med
This is because, depending on the ida unitary part, there is always diversity following the expansion and contraction width of the fine adjustment. On the other hand, there remains a variable width that has not been adopted as a more convenient structural solution under other conditions. For the middle auxiliary parts are all the same 20 mm and the total width of the single piece stretch package is 9 mm. This leaves 10 mm openings unopened for removing 20 mm (addition or removal) of successive auxiliary parts in each symmetrical half of the rolling mill.

To this end, the invention is characterized in that each symmetrical half of the rolling mill consists of: That is, the end portions of the vertical and horizontal activity sides. It belongs to the positionally changing part, in which there is a cabeza with means of blocks in relation to the gears of the hauling mill.
l), and it is also firmly connected to the screw fastening means that operates according to the external clasping means.

An exchange table equipped with means for moving and moving along the rolling mill. With this stand, the clasp of the transport head at the end (en
means are activated.

Means for the movable position of the clasping means on the exchange table.

Horizontal and vertical removal means at the end of the hauling mill.

Means for withdrawing the end part on the front or fixed side of the rolling mill and means for reinserting the end part in the new position of the longitudinal adjustment of the rolling mill.

Means for opening holes between auxiliary portions for reinsertion of the distal portion.

Dimensional compression and adjustment means for the length of the rolling mill.

Suitable detachable means for the selective auxiliary portion of the end portion.

In essence, the idea and function of the new method of constructing a rolling mill is that the various parts to be modulated (center, telescopic part,
Each of the auxiliary parts and end parts has its own tolerance range, which works in all cases, the end parts modify their relative position, and the specific position of each is determined by the rolling mill. Apply to determine the length. When applying the maximum possible length (during the manufacture of the rolling mill), it is common for the entire length of the rolling mill to have only an availability that falls between these end sections. Therefore, the end part
It is formed by two adjacent lip-like sides (longitudinal, lateral or lateral). It is also integrated into a cradle with optional blocks associated with the transport gear. It is also fixed and moved by automated means incorporated in the rolling mill. Small head,
It also incorporates an isolation section and creates space at its end for vertical (horizontal and lateral) operation (for continuous folding of adjacent sides of sheet material of different sizes).

In particular, the retention of space can be selectively defeated, providing great selective applicability during the working process. In addition, automatic selective assistance of each end section is considered as an additional assistance of 10 mm in length, covering dimensional spacing that has traditionally disrupted the continuity and progression of longitudinal adjustment. . It is also based on the 9 mm variable capacity of each telescoping section and the use of 20 mm auxiliary sections.

As a result, this new method is for manufacturing panels on a rolling mill, but its operating length (between the minimum and maximum lengths in manufacturing) is controlled by a numerical control system. The continuous progressive method is applied, and the maximum level of productivity can be achieved. Conceptually, it is simplified to a vertical adjustment operation (which is now also automated). In addition, it is possible to eliminate wasted time, promise high machine productivity, pursue high profits, and eliminate auxiliary parts and their storage means.

Regarding the thin plate operating device, the following new contents are included.

Means for rolling and rotating thin plates. It is connected off-center to the central vise. The upper vise jaw spins and the lower vise jaw rotates.

An operating means that rotates in synchronization with the lower central vise jaw. Also an additional, off-center means of rolling and rolling of sheet metal.

A direct angle means (endoder) connected to the axis of the lower vise jaw. It operates by connecting to a central management computer with an operating program and the necessary corrective measures.

Circulating ball bearings (balas re)
The operating means for the vertical movement of the operation support base by the spindle with the circuit (circles).

Mechanical type for detecting and measuring the position dimension of the thin plate,
Electrical inspection means. It operates by connecting to a central management computer.

An important feature of these proposed structures is that in addition to the central vise described above, a conical pad (zap) is used.
atas conicas) to the vise. Aligned with the second fastening point of the sheet, it is very efficient and has the function of eliminating relative slip reduction in vertical and angular slip. This feature is that the rotational movement of the lamella results from the decentering addition of this conical pad. Also, the new lower pad rotates in sync with the lower half vise.
Similar to the central part of the vise and on the basis of other characteristics of the invention, this additional, decentered means of rolling and rolling of sheet metal was made with two conical pads operating through the sides. Have power. The upper conical pad idles at the movable point of the rod of the second hydrodynamic cylinder, and the lower conical pad is connected to the oblique shaft which rotates in tune with the lower vise. For the other schemes, the presence of a second grasping rotary operation makes the force for rotation relatively small, has little effect on the relative slip, and facilitates the accurate handling of heavier sheets, In addition, it is always desirable from the viewpoints of material durability, mechanical failure, and extending the service life.

When there is no relative slip, with respect to the vertical axis of the central vise, the longitudinal and angular measurements are very advantageous and indeed an exact match. Also, the combined work will be very accurate.

As already mentioned, the final accuracy depends not only on what the device does, but also on the initial exact position of the sheet. This invention emphasizes this point of view, but not by pursuing accuracy to determine the initial position of the sheet, but by making automatic corrections and making inspection and sizing systems. . this is,
It is the theoretical center of operation of the thin plate, and we will calculate what is efficiently held by the vise there.

As described above, according to the present invention, the inspection device and the measuring device for the position of the thin plate are provided. They are the mechanical brakes installed on the opposite side when the lamellas on the workbench come in, installed against the third hydrodynamic cylinder propulsion unit that opposes the regulator of this brake. There is. A visual ruler is used to detect and measure the vertical position in the stroke of the movable support. Therefore, Vise uses the data of the central management computer to capture the thin plate.

The vertical barrea of the laser bundle is
Aligned with the folding plane, they detect the front edge of the sheet and also send the data to the computer, which first serves two purposes. The first is to correct the computer work program appropriately so that the theoretical center position that matches the vertical dimension is taken on the thin plate, and the front edge of the thin plate simultaneously cuts into the laser fence. Secondly, when one part of the laser fence reacts ahead of the other, the sheet rotates,
At that time, an accurate rotation command is sent to the vise, and new angular position data is sent to the work program, which is the basis of rotation for performing the bending process. A direct angle sizing device (protractor) senses the lower half vise axis angle and feeds that data to a computer. This special position is
It has the advantage of producing fast and accurate work, eliminating the need to hold the lamella precisely due to its geometric center and to determine the movable support (and also the central vise axis). However, a protractor, visual ruler, and sensor system formed by a laser, combined with a management computer, introduces accurate dimensional numerical values into its internal data, which allow vertical position, precise angle to relate to vise. Is determined by these sensors. That is, the new system modifies the true center of trapping of the lamella to move to the theoretical center of motion. This causes each edge of the lamella to first of all approach the laser fence. the same way,
If the edges are correctly located, a detection is made to correct the initial angular position, and if the edges are not, then a correction is made that matches the computer data.

In the detailed description, regarding this new operating device, the maximum number of movable devices will be shown in the additional drawings.
The various methods and the special method of lower half vise and the synchronized rotation of the conical pad are appreciated.

As for the movable means for the vertical movement of the movable pedestal by the spindle with the circulating ball bearing having the maximum accuracy, the maximum operability and the minimum maintenance are required as compared with other hydraulic devices. Regarding the method of raising the thin plate separated from the support on the workbench,
Its operability is simple.

In another aspect, in the tangential folding process, the proposed new structure has upper and lower pawls, which are individually supported by each up and down moving arm. At this distal front, and near the outer flank, it is moved by a vertical hydraulic cylinder so that the upper arm moves up and down with respect to the upper folding claw, the lower arm moves up and down with respect to the lower folding claw, and has its own axis of rotation, Located parallel to these claws, on a table that can move horizontally and transversely to these claws. This platform has horizontal mechanical pressure means for adjusting the points of action of the pawls for bending the thickness of the sheet. This is a hydraulic horizontal pressure device, with the pawl working so that it can be bent over a right angle.

The first advantage of this new method is that it achieves a perfect tangent condition that can be folded to a right angle,
There is no need for an additional series of corrective movements as well as up and down movements of the nail carrier arm. This leads to great structural and functional simplicity and high productivity. Furthermore, it operates efficiently and the product quality is high. In the mechanical structure, the axes of rotation of the upper and lower arms are parallel to each other, and they are in a position where they can be supplied vertically to each side surface of the work horizontal plane and exchanged with each other. The axis of the folding claw carrying arm from below the horizontal plane appears, and the axis of the folding claw carrying arm from above the horizontal plane appears.

Other advantages of the proposed structure are:
A hydraulic vertical cylinder, which moves the folding pawls, is installed whenever it is independent, which makes it possible to carry out the rolling process and to be dimensioned with minimal force.

According to a suitable implementation of the invention, the mechanical means for the horizontal push-out of the hauling abutment of the arm are such that, on the side of the back, the hauling is tied to a fixed wedge and connected to the movable pawl to rotate the motor. It runs along a continuous, fixed-axis, moving spindle. This pawl system structure is for adjusting the functional parameters (approach or distantness of the bending pawl) in idle according to the thickness of the thin plate. This is much easier and more accurate than other lever systems or other hydraulics that are always running at compression ratios that prevent accurate adjustment. Moreover, the forces can be distributed appropriately to provide structural support.

The hydraulic method of horizontal pushing out of the carrier is, in particular, that each hydraulic cylinder operates between its base and the machine frame, with its axis aligned with the working horizontal plane. This method ensures that the movement of the cylinder is above the right angle (90 degrees) in the upper fold. At this time,
The thin plate thickness adjusting means is not connected to the thin plate thickness adjusting means so that the thin plate can be efficiently processed.

Regarding the rolling machine for fixing the thin plate,
According to the invention, it is supported by a hydraulic vertical cylinder which is connected to vertical linear guide means and which carries out the steps for fixing the sheet and releasing it after folding.

Based on the above-mentioned design drawing, its related matters, and the attached drawings, an optimum example among various methods for satisfying the object of the present invention will be described. This relates to the panel manufacturing machine shown in Fig. 1, which is usually supplemented with a workbench (2) and a manipulator (3), by which a fixed vise jaw (5) and a movable type at the bottom are attached. The upper vise jaw, that is, the rolling mill (4), holds the thin plate in an appropriate position (FIG. 2A) and creates various types of thin plate (19). By this method, the bent edges (20, 144a) of the panel are continuously formed (FIGS. 2A and 9 <19> in the drawing).

The object of the invention is focused on the peculiarities (FIGS. 4 and 5) of the stretchable part (9) in the structure of the rolling mill (4) (FIG. 3). In the best case, there is a multiplicity of individual unit parts (10), a pair of inserts in each recess (10a) of the internal expansion-contraction part (11), and also each continuous expansion part (10). Make a play (12) in between (Fig. 5A). At the same time, all the telescopic parts (10) are pierced by a spindle (13) fixed to the shaft, joined by a movable shaft nut and joined to each telescopic part (10). Thus, the device rotates and determines the pressure against the force that causes the telescopic deformation of the washer (11) for mounting the successive parts (10) (Fig. 4A).

In this construction, between the minimum value in the installed state (maximum pressure) and the maximum value of all the sum of play created between these elastic parts, all elastic parts (10) are You can adjust the length. A very suitable shape would have up to 1 mm of new play.

Based on this, the optimum one of the structure of the rolling mill (4) for each side of the central part (6) shown in FIG. 3 is adapted to the respective expandable part (9) and auxiliary part (7). And tailored to the end portion (8) to the required dimensions. In particular, this structure can be applied up to 18 mm in length, creating maximum play (Fig. 4).
And part 26 shown in FIG. 5).

Each play (12) is between the washers (11)
Each padding (14) was connected to each of the individual parts (10) one by one so as not to exceed its maximum limit by compromising the uniformity between the. In this way there is one flat eyelet (15) in the center and also the screw (17)
Fix this filling with. Each simultaneously adjacent individual part (10) is properly connected to the rod with a screw (18) so that it moves smoothly into the measured hole (16). In terms of expansion and contraction, this should be within the range that allows the required movement of the screws (18) (and thus also the movement of each individual part). In this way the play (12) remains the same and of maximum size for all parts.

With a sufficient array of these paddings (14), for example, as shown in FIGS. 4 and 5, each single piece (10) is at least continuous in its continuity by at least one padding (14). And make sure that none of them are separated by more than the size of the corresponding hole (16).

Similarly, according to the design drawing and the related instruction,
The optimum continuous method for automatically adjusting the length of the rolling mill (4) in the panel manufacturing machine will be described in detail below. For a non-limiting arrangement, the movable rolling mill (4) has already been illustrated in the process as being placed on the sheet (19).

Considering the special means of making this new method, it essentially consists of a terminal portion (118) with vertical and horizontal active sides, which is also replaceable (10).
8), which is positionally tightly connected with a head (120) attached to the means of the block which is connected to the gear (104) of the rolling mill (4).
Also, fix the screw so that it works in accordance with the clasp that is exposed to the outside. A transmission (111) equipped with a transmission installation running along the rolling mill (4) drives a catching device of a removable head (120) of the end part (118).
This transmission (111) determines the movable position of the clasp device. Attachable rolling mill (4) gear (104)
To effect horizontal and vertical removal of this end portion (118). Withdrawal of the end part (118) is carried out by the stationary part at the front of the rolling mill (4). Further, the reinsertion is performed by placing the rolling mill (4) at a new position by adjusting the longitudinal length. The hole between these auxiliary portions (7) is used for reinsertion of the end portion (1118). The length of the rolling mill (4) is adjusted and packed. Terminal part (11
Appropriately apply the movable parts and auxiliary parts of 8).

Subsequently, different desirable steps will be explained.
The function of the change cycle, as well as the length of the rolling mill and the auxiliary part of the end part (118) installed on the replaceable part (108) will be detailed. As shown in the previous document, in some cases the expression "cylinder retracted or pulled out" is a simple descriptive method, where each of its rods is not actually a contraction or extension of the cylinder. It will be used to show in a simple descriptive way what is associated with the cylinder body of.

The rolling mill (4) is supported by the gear (104).
The dovetail tenon (104a) is used, and dovetail tenon (with its own block material) is similarly connected. This is designed to be movable vertically with respect to the framework (1) based on the support (103). Cylinder (1
According to 43), when it is operated, it is in a logically extended state.

Since there are many working positions of the small head (120) in relation to the dovetail (104a) of the gear, the method for making the necessary blocks is a dovetail made of the small head (120). It is on the movable side (123) that fits the female part of (Fig. 11, Fig. 13, Fig. 14), and its side (123)
Are integrated at least at the rod of the horizontal cylinder of the block. In particular, there are two cylinders of the block (122), which act on the movable part (123) only once or on each independent part of the movable part (123).

In order to supplement the small head (120),
To extend or reinsert it in relation to the rolling mill, such as to pre-draw it,
The wedges of the small head (120) are placed in the holes of the clasp (121) so that they work transversely in union with the components for proper expansion and contraction. At the same time, the external clasps have bearings (1) corresponding to these clasp holes (121) respectively.
33). It is connected to a telescopic adjuster, and its protrusions are replaceable, allowing a vertical cylinder (13
It can be removed horizontally with respect to the clasp of 4). This cylinder moves according to the length of the exchange table (111),
This bearing (133) and cylinder (134)
They are joined by a clasp head (132).

The part for moving the exchange table (111) is shown as a horizontally fixed auxiliary spindle (FIG. 8), which is rotated by the servomotor (114) and its rotary exchange table ( 111). These are replaced by a framework stand of the folding machine, and in parallel with this spindle, a horizontal plane is formed in parallel, in which each slide (127) connected to the exchange stand (111) moves smoothly.

The exchange base is provided to take the preferred operating position of the head (132) for the clasp bearing (133) and the horizontal cylinder (134) to be connected by the clasp head (132). It is operated by a drawer (115) that can be slid vertically on the slide and by a sliding part (129) that slides into each vertical groove (128) connected to the wheel base (111).

The withdrawal operation of the replaceable part (108) requires horizontal and vertical (FIG. 12, FIG. 15) removal in connection with the dovetail (104a). As a result, horizontal removal by the horizontal cylinder (134) is performed on the second table. In succession, the first clasp and also one or more of the cylinders of the block (122) create a retraction of the movable side surface and retract. The platform that is moved horizontally and removed is wider than the horizontal section connected to the dovetail (104a). It is also carried out on a table (115) that is forced by a second vertical cylinder (131) and installed on this exchange table. These means also allow the replaceable portion (108) to be reattached by a series of reverse operations.

The means for pulling out the end portion (118) by the front portion of the rolling mill (4), that is, the immovable portion (FIG. 12, FIG.
6) and with respect to its reinsertion means, this horizontal cylinder (134) is retracted and extended on each successive stage. It has the same width as an enlarged version of two consecutive pedestals of the small head (120). Also, the corresponding portion of the dovetail (104a) is taken horizontally. Also, they partially conflict with or coincide with these platforms.
This same means allows reinsertion, followed by the reverse operation.

The means envisaged to adapt the opening of the hole to the auxiliary part required for reinsertion into the replaceable part are at least horizontally extending for operating on this platform. Install the pawl (116) (FIG. 16) and also at the end of the rod of the horizontal cylinder thruster (136). The reciprocating box (142) installed between the two auxiliary parts (17) is provided with the claws (116) so as to move vertically at the same height. These vertical cylinders (130 and 131) are in the extended state when the arrangement is adjusted to a modified position or when the rolling mill (4) is fully lifted by the cylinders with length adjustment. The pawl (116) can also be selectively replaced for some of these boxes (142) by horizontal movement of the platform (111). This movement creates a slip of the auxiliary part (7) in the hole and reinsertion of the end part (118). Especially in (Fig. 9),
The pedestal (115) is supported by a pair of pawls (116) and corresponding cylinders (136) and is symmetrically placed on the head of each clasp, optionally with a hole in each part (7). It is designed to move faster than the opening. They are located lower than the clasp head (132),
It is supported by a vertically extending portion of the table (115).

As shown in FIG. 8, the related means for reducing the working length of the rolling mill (4) and adjusting the dimensions is supported by the main body (103) based on the maximum length applied by the rolling mill (4). The
In addition, the propulsion unit (14
The operation according to 5) is tied to the end of the rolling mill (4) and fixedly and auxiliaryly screwed onto a sinfin spindle. It is driven by a servomotor, firstly the holes are made smaller by changing the position of the end part (118) and secondly the length is adjusted in proportion to the capacity of the telescoping part (9).

Regarding the selectively movable part of this end part, the additional part (117) moves on the support (137) and the cylinder (138) placed at a long distance with respect to the rolling mill (4). ) Is mounted on this stand (115).
This auxiliary part (117) comprises a scissors (13) driven by an associated vertical starting cylinder unit (140).
It is pressed down by 9). Also this end part (118)
Placed in a moving position with respect to. The modified position then has complementary wedges (141-125) that capture this end portion by the retracted cylinder and the extended cylinders (130) and (131) and join them together. These movable means do not necessarily have a special structure in which the length is adjusted by the movement of changeable parts. However, these structures are modified by the terminal auxiliary part (1
It is used for operating 17) and has a movable length of 10 mm so that it can be applied to the adjustment length of the vertical edge of the rolling mill (4), and gradually extends it. However, 9 mm of the exact adjustment dimension of the stretchable part and 2 of the auxiliary part (7)
Exceptions are intervals of 0 mm.

Also in the present invention, in the replaceable portion (108) there is a vertically moving isolation portion (119) additionally located on the side of the end portion. This part (119) has a small head (120) and a cylinder (12).
4) movably tied through, and in the distal working position, this section (118) and (119) separate and a continuous cross-section appears at the working longitudinal edge of the terminal section (118). Here, the maximum capacity of operation is given to the planned bending portion.

Despite its operational adjustment being performed at a different time than the length application cycle, due to the similarity of its method and function, the two vertical cylinders (130) (13
In position 1) there can be vertical cylinders which can reactivate these platforms in an independent manner.

On the basis of the details made for the scheduled process, the automatic cycle of longitudinal adjustment of the rolling mill (4) is subsequently described exactly. Cylinder (1
Starting from the extended position of 44), the thin plate (144) is placed on the rolling mill (4) and the thin plates are pushed into the cylinders (130) (131) so that in the rolling mill (4) these replaceable parts (108) Integrated.

Thus, this repositioning cycle or repositioning of the changeable portion (108) along the rolling mill (4) proves to have the following consequences. That is, the support cylinder (14
3) is pulled and the rolling mill (4) rises to its tip. The first vertical cylinder (132) of the drawer (115) is withdrawn throughout its travel. The horizontal cylinder (134) of the clasp head (132) extends its pawl claw travel and stops at these replaceable portions (108). Pull out one or more of the cylinders of the dovetail (104a) block of the gear (104) on the rolling mill (4).

That is, the horizontal cylinder (134) of this pawl provides the horizontal removal of the base of the replaceable part associated with the dovetail (104a). Drawer (11
The second vertical cylinder of 5) provides vertical removal of the replaceable part (131) associated with the dovetail (115). The horizontal cylinder of the pawl (132) is withdrawn complementarily and the convertible part (108) is withdrawn by the (fixed) front of the rolling mill (4). Conversion stand (111)
Moves to the pawl (116) chosen for maximum performance in line with the box (142) of the auxiliary box (7) and is occupied by the replaceable part (108). Go to the position. The selected nail (116) is extended and inserted into the box (142). The conversion table (111) is moved to puncture and the replaceable part (108) is reinserted. The selected nail (116) is pulled out. The horizontal cylinder (134) of the pawl (132) is fully opened to create a reinsertion stroke, which is the total stroke of the pawl that can be removed horizontally, but the second vertical cylinder (134). Is pulled out, there is a tenon (104
Vertical removal is possible in a). On the scale of the horizontal removal process, the horizontal cylinder of the ratchet head (132) is pulled out, allowing horizontal removal on the dovetail (104a).

Creating an expansion of the cylinders (122) of these blocks, in relation to the arbor (104a),
Fix the new position of the replaceable part (108). With this end portion (118), the new rolling distance of the rolling mill (4) is defined, and this isolation portion (119) is at the location separated from the end portion (118). The horizontal cylinder (134) of the ratchet head (132) is pulled out of the ratchet stand and the stand comes out. This first vertical cylinder (130) is fully withdrawn and the drawer (115) remains in its starting position. The rolling mill (4) already has a new working length applied and stays in operation as the cylinder extends. The cylinder is supported through the carriage (103). The transport-roller (4) gear (104) reinsertion is also done if necessary.

With respect to the selective assistance of the end portion (118), in relation to the additional portion (117) towards the end portion (118) of the modifiable portion (108) (or vice versa), the support (137). ) Of the rolling mill (4) during the vertical mounting operation of the rolling mill (4) when the rolling mill (4) is raised to the uppermost position and when the drawer (118) is lowered to the maximum. And based on a series of sequences relating to the operation of the auxiliary part of the end part (118). Through the vertical cylinder of the support (137), the end portion (11
Slide in the attachment of the terminal auxiliary portion related to 8). Through the longitudinal cylinder (138) of the support (137), in relation to the end portion (118), the end auxiliary portion (11)
The unintended movement of 7) occurs. In this case, the wedge (141) is installed between the wedge holes (125). The vertical cylinder (140) exposes the opening of the clipper (139) to release the stop of the distal auxiliary portion (117). Finally, waiting for the distal auxiliary portion (117) to be pulled out by a series of reverse operations to the above, by moving the vertical cylinder (138) in the opposite direction, the support (138) is separated. Return to the position.

With respect to the operations of assisting and unassisting, the operation of dimension adjustment is repeated, and the following four different distinct situations are shown. That is, a) end portion (11
8) There is no 10mm gap between the end support part and they must be lined up. b) Where the end portion (118) is attached to the end aid and must be retracted. c) and d) Terminal part (11
8) is not attached to the terminal auxiliary portion (117),
And if it is not needed, or if it needs to be stuck and still stuck there. In the two cases, it would not be necessary to perform any movement when dimensional adjustments should be performed in this cycle.

In FIG. 11, the unique means of the dovetail (104) block (104b) in the gear (104) of the hauling mill (103) is well known,
It is also used for fixing all rolling mill (4) parts throughout the work cycle.

In some well-known panel-making machines, the short sides of the sheet (144) are continuously subjected to the first bending work, and then the long sides are bent to make each end lip-shaped on the sides of the rolling mill. Allow the parts to be placed beforehand. This also prevents some folding operations at each end from joining the short side in a moving manner after the side of the long section (eg folding the short side over the long side). In FIG. 21, according to the invention, when the replaceable part of the rolling mill (4) is assembled with the end part (118) in the isolation part, the “continuous” of the isolation part (119).
It is intended to make sure that the two are glued together in position (119a) so that the end piece (118) can bend the machine continuously on the long side of the sheet (144) before the short side. And, I acquire the operation method that I could not do until now.

The proposed operator preferred implementation is relevant for a given configuration of the movable support (3), by means of vertical wheels (223) and horizontal wheels (224) which are movable based on a ruler (204a). A vertical plane (20), which is supported by a frame base (204) and is bent.
It can move vertically at a right angle to 2). According to the invention, the power means for the vertical movement of the movable support (3) is a second motor, which comprises a pulley (226).
-227) transfer its rotation to a continuous horizontal spindle with a fixed rotating bearing (222), and the rotating or screwed capsule is connected to the base (203a) of the rotary support (3). There is. This system provides the accuracy of operation described above and requires less maintenance management than any other.

With this operating type support (3), the central vise set (206-207) is operated, and the conical pad (2
15-218) The same applies to the set. At the same time, the two perform vertical and angular formation and transport of the sheet metal (19) in its correct working position. The lower part of the central small vise (107) and the lower conical pad are simultaneously driven by the first motor (204). The motor is rotated by a vertical shaft while the horizontal axis (212) runs continuously and meshes with a gearbox (210) pinned to the shaft in the lower part of the small vise.
At the same time, on the other hand, pin the pinion (221) attached to the diagonal shaft of the lower conical pad (218). On the other hand, the upper part (206) of the central small vise and the upper part (215) of the conical pad move vertically and first of all, the rod (208) of the first hydrodynamic cylinder (208).
a) and then these vise (206) and conical pad (215) by means of a second hydrodynamic cylinder (216) externally coupled to a vertical gear (217) for its activity. Is a rod (208a, 216)
It is attached to the location of a) so that it can rotate freely. It also rotates freely to move the lower side (207) of the small vise and the conical pad (298).

Upper small vise and upper conical pad (206,
215), the lower small vise and the lower conical pad (207, 2
When a lamella (19) is inserted between 18), the lamella is moved at an angle to the length to reach the working position, where one of the edge fringes or rims is folded. As already explained, this new method is suitable for thin plates (19).
Allows additional isolation to allow work without relative slippage. The efficiency and accuracy of this work can be done easily and with little effort. In addition, a thicker and heavier sheet (19) is possible, which the folding machine (1) can accept.

Particularly, the control of the operating position of the thin plate (2
28) is executed by the following. That is, the axis (20
The adjuster (211) and the visual ruler (231) that determine the angular position of the rotation of 9) determine the true position and movement of the shaft, and the operating support (3) with respect to the bending surface (202). Move with distance. Move the laser fences installed along the folding surface (202) and the means used in those elements to give execution commands and shift the true position of the axis (209) from the theoretically expected position. If there is a central management computer that makes corrections to the work program data.

The proposed new function starts with the material supply side. There, the lamella (19) is pushed along the worktable (2) by a third hydrodynamic cylinder (Fig. 26). The appropriate execution is performed on the side end portion (229) opposite the entrance end. At this time,
The lamella (19) is simultaneously sandwiched by the central vise (206-207) and the conical pad (215-218), sent to the working position, and its front edge has a laser fence (23).
Go to where it is detected by 2). At this time, one of two things happens. That is, all front edges of the thin plate (19) are simultaneously detected by the laser fence (232).

In this case, the central control computer compares the position measurement of the axis (209) with the programmed position. If they match, start the program,
If they do not match, modify the program, measure the correct position, determine the new associated position and put it into action. The lamella (19) is then moved to the rotational position, and its front end does not activate all of the laser fences (232) simultaneously. Then, before putting the program into operation, make sure that you have the right perspective (215-21
8), the executed rotation data support the correction criteria of the program, and finally become the new criteria of rotation of the achieved angle and position.

It is desirable that the inspection means and the measuring device of the position of the thin plate (19) are of a well-known, mechanically, regular, controlled and centralized type.

The lower conical pad (218) for versatility in the operation of the thin plate (19) on the workbench (2).
A vertical rod (233) is installed near the. It can be moved axially by the operation of the hydrodynamic cylinder chamber (234). This is a position that is hidden under the work horizontal surface (2), and pushes out the lower end position in a stopped state and the thin plate (19) whose point is not in contact on the work horizontal surface. Between the movable upper end position to be driven.

As shown in FIG. 24, the supporting angle changing device attached to the upper vise is connected between two parallel halves by an intermediate ball joint (206c), and is connected to the lower half. On the other hand, a variable supporting angle can be applied to the thin plate (19). In this way, the irregularities on the surface of the thin plate (19) are corrected.

For angled continuous folds, the special positions planned are clearly shown in FIG. 27, where the upper fold claw (305) and the lower fold claw (306) are each individually distal. Mounted as independent arms (307, 308) on each of which, as each vertical hydraulic cylinder (311, 312) moves, the shaft (309, 310) is correspondingly moved up and down. For example, if you want to bend up, lower cylinder (312) and lower arm (30
8) moves towards the work surface (2) (see position of line). The maximum movement is possible according to an angle made more or less at right angles or less. Therefore, for bending up to 90 degrees,
Up and down movements of the arm (307 or 308) are sufficient. For bending over 90 degrees, it is necessary to combine horizontal movement with the thin plate (19).

In order to obtain the proper condition of the tangent line in the working stroke of the arm (307, 308), its up and down axis (30
9, 310) are superposed so that they are simultaneously opposite with respect to the work surface (2).

The rolling lines made by the inner edges of the rolling mill-cradle set (4-5), in the absence of anything,
According to the thickness and bending angle of the thin plate (19), the working point of the bending claw must be corrected so that it can be accurately applied, and in addition, it must be able to be bent vertically by 90 degrees or more in the operating state. I have to. In order to make such positional movements interchangeable, these axes (309, 310) are mounted on a platform (313) which is movable transverse to the folding line.

At this time, the movement in the empty state is performed by the motor, and the fixed axis infinite spindle (31
6) (Fig. 29) through the vertically movable wedge (31
5) to move the fixed wedge (314) connected to the base (313) to make a right-angled (horizontal) movement.
Further, the movement in the movable state moves the horizontal cylinder (318) installed at the fixed point of the table (313) and the framework (1).

27 and 28, the installation of the rolling mill (4) supported by the cylinder (304) and set so that its ascending / descending stroke is vertical and straight is clearly illustrated. Shows.

Although the contents of the present invention and the realization of industrialization thereof have been sufficiently clarified, the last thing to be added to the whole or part of the contents is to change the form, material and position within the scope of the contents of the invention. It is possible. In that case, those modifications must not distort the basics of the invention.
