Description

[Detailed description of the invention] Contains a thin layer of adhesive on the receiving conveyor.

Uncured thin sheets of soaked slag cotton Delivery method and device The present invention feeds a receiving conveyor with uncured sheets of slag cotton impregnated with a thin layer of adhesive. With respect to the step of performing It also concerns the location.

When manufacturing a mineral wool sheet, it should be made as uniform as possible because it produces a high degree of insulation performance. However, it is difficult to finish the product uniformly, and on top of that, the density is low. The material should be as elastic as possible, and the fibers should be stretched primarily on the sheet surface. Due to its elasticity, this sheet is compressed for the filling and transport stages.

In order to achieve this, the basis weight is in the range 110 to 450 g/m2 The thin primary lamina varying within the range preferably has a thickness of lOO to 200 g/m. 2 are collected on a collection conveyor immediately after fiber disassembly. −Next, the thinner the thin plate, the better the finish. The product quality is good, keeping the force at the desired level when producing thin primary sheets. In order to The speed of the −th sheet is more than 100 m 7 minutes, but the basis weight of the −th sheet is simply in the range of 100 to 200 g/m2 and maintain the capacity at the desired level. A constant high speed is required to achieve this.

US Patent No. 1 from 1948 on various methods of folding slag cotton, No. 2,450,916, and more recent patents among other patents. It is disclosed in British Patent No. 772,828. These patents are a pendulum Next, we completed a method for folding primary thin plates using a type conveyor.

When a pendulum type conveyor is used to deliver the primary sheet, the speed at the sending end is faster than the primary sheet. is the same as the speed and thus the folding or pulling of the sheet at the moment of delivery. It is designed to avoid stretching. That is important.

Currently, this pendulum mechanism generally operates only when its distal point is connected to the receiving conveyor. the highest point above the conveyor, and the bottom dead center of the pendulum is closest to the receiving conveyor. ing. To provide the desired capacity for thin primary sheets, the delivery speed of the pendulum conveyor must be should be increased, but this is not possible with the known device. In fact, light A high-speed pendulum type conveyor with a high period of pendulum conveys a large amount of thin plate and There are inaccuracies in the placement of the plates. Driven in a known manner by connecting rods and arc A pendulum conveyor that is oscillated along adds velocity to the delivery end of the conveyor, This conveyor is at its highest point when the pendulum is in its central position, and at its distal point. , it decreases to zero in a sinusoidal manner, and from this distal point it decreases in a sinusoidal manner. Acceleration occurs again. At its lowest point, the delivery end of a pendulum conveyor is -thin To place the boards in an even layer on the receiving conveyor without being stretched, The length of the thin cotton board is approximately 0.2 times the length of the sending section, which is generally 2 m, but this is the case. The distance between the pendulum and the receiving conveyor, which must be placed or longer, the edges of the delivery lamina are uneven, and the delivery speed is approximately 13 0 m/min, and the degree of irregularity of the formed secondary thin plate is about ±5% of the sending part.

This fact indicates that the secondary sheet must be made dependently larger in order to achieve a defect-free sheet with the desired width. A wide width must be provided because the undesired material has already been cut. This is because that. This represents a significant loss of material.

Pendulum delivery mechanisms are known in which a folding process is carried out, It continuously delivers the primary sheet while maintaining a constant height on the support. Receipt One joint that maintains the delivery end of a pendulum conveyor at a constant height above the conveyor. system is provided, and the chain/connecting rod mechanism provides free movement/approach movement. . Looking at the speed of this vibration movement, it is constant in the center and at both ends. Therefore, a synoidal deceleration and acceleration phase occur.

The pendulum must be decelerated quickly and then accelerated at the end; this is a change in the feed rate of the primary thin plate per unit time while creating a large strain in the machine structure. This is because the Riko movement responds. Therefore, this mechanism can be used for transport of approximately 100 m or less in 7 minutes. Used only for exit speed.

Another disadvantage of pendulum mechanisms with high pendulum frequencies is the large surface area of the thighs. This is a strong airflow caused by the rapid back and forth movement of the pendulum mechanism. This air flow Prevents deposition of thin primary plates on the substrate surface.

In conventional technology, the digging mechanism is used to collect overlapping layers on the receiving conveyor. A thin primary sheet is then fed. However, all these conventional techniques are quite lacking. There are points: the edges are not flat, there is a lot of material loss, and the speed is too slow for the desired The deceleration and acceleration forces are strong and cause large mechanical stresses due to the structure; Air flow problems compromise the deposition of the primary sheet.

The object of the invention is to reduce or eliminate these disadvantages, in particular to It is important to perform the setting accurately and to set a highly homogeneous thin plate, and also to The method whose main features are as set out in claims 1 and 9 This has been achieved by providing a device as well.

In a preferred embodiment of the invention, a known drive device is used, hereinafter the pendulum For a vibrating pendulum conveyor called a and the sinusoidal function at both distal ends of the pendulum motion, respectively. This is causing a decline and an increase in the rate of decline. During the period of constant speed, the pendulum oscillates completely. It is in the range of 30 to 60%. Even in the center, the constant speed of the pendulum is linear At approximately half of the distance given entirely or mostly to the sheet delivery speed. This causes the pendulum to be set close to the receiving conveyor surface, resulting in It is guaranteed that the deposition and fixing of the primary sheet on the receiving conveyor will be carried out in a very good manner. ing.

In the outer wall of the motion phase with constant speed, each pendulum has a sinusoidal function. Reduce the rate at which it is driven to increase, while the pendulum continues its pendulum motion. pendulum During the movement, at the distal end of the rocking movement the respective increase rate decreases, At least the delivery end of the pendulum is arranged to rise during the final phase of the pendulum movement. It is arranged so that it sinks during the rising motion phase. Deceleration of each phase of acceleration motion Due to the change in the pendulum height over time, the sending end of the pendulum changes over the entire swinging process of the pendulum. This creates a stress in the mechanism that is less than that created when drawing a horizontal path across the .

A central part with a constant speed and two distal parts with both deceleration and acceleration speeds. The pendulum motion consisting of the endless drive chain running on the coplanar clearance chain wheel 29a can be obtained appropriately using The connecting rod thus transports the pendulum on the driving chain. Connect to the body. The center distance of the chain wheel corresponds to part of the pendulum motion with constant speed. Moreover, the half circumference length of each car corresponds to pendulum motion with deceleration and acceleration speeds. .

A central part with a constant speed and two distal parts with both deceleration and acceleration speeds. The pendulum motion consisting of the In this case, the rotational movement is transmitted by an elliptical gear wheel.

The sending end of the pendulum moves along different shaped paths within the path of pendulum movement. You will be guided. The simplest implementation is an arcuate fixed-angle orbit, which allows the bearing to A pendulum swings around a stationary point. In such embodiments, the actuation of the pendulum is Very accurate and maintaining a delivery speed of approximately 200 m/min, this means that the delivery end of the pendulum are placed on the receiving conveyor very close together, with the most conveyor As a result, the delivered primary sheet is immediately fixed onto the lower delivered cotton sheet. and thus remains undisturbed by the airflow caused by the pendulum movement. situation manifest the state of affairs. In both distal portions of the pendulum motion, the lower end of the pendulum is approximately 0.0 mm of the delivery width. Only 1 times higher. In other words, if the sending end is 200 cm, there will be a rise of about 20 cm and a bend at the end. It is in a more accurate position relative to the bend. This is because the bent part of the cotton thin plate is small. evening. Another advantage of this embodiment is that the pendulum is relatively short, The mass of the tip is small relative to the delivery width, that is, about 140 to 200 cm, Stresses in the drive are low, and air flow disturbances are also reduced due to the short pendulum. It will be done.

In this embodiment, the pendulum has an approach point 5 to 10 cm above the receiving conveyor. It can be adjusted so that it can be placed on the As soon as it enters the central part of the fixed angle orbit, it becomes fixed and usable. As a result, 1Is-th The lamina will have an averaged edge. At a constant speed of approximately 50% or more of the delivery width, That is, at 200 cm, the maximum pendulum swing is 80% and the pendulum is approximately 75% of the delivery width. length, i.e. 150 cm, the pendulum at its distal point is about 12%, i.e. 2 Go up 4cm.

In another preferred embodiment of the invention, the pendulum and its delivery end are arranged in a pendulum oscillating motion. In the central part of the movement, horizontal movement is forced at a certain height above the receiving conveyor, and It rises more to this extent in the outer position.

The upward motion begins at any point after the pendulum passes the center point of its swinging motion. , but if carried out in this way on the primary plate at the most delayed position during the deceleration phase during the pendulum motion, The sending end of the pendulum is sent out at a constant speed, and in this case, the thin plate is placed well below the sending end. This delivery end is then operated at a speed slower than the delivery speed of the primary sheet. It will be done. As shown above, the upward movement is at its earliest just after passing the central part of the pendulum movement. starting at a point, the pendulum and its sending end then trace a continuous arc, or The child movement starts at the latest point before reaching the distal point. And swing There is enough space for the pendulum to swing, and there is space under the rising pendulum. The interval is to keep the deposition loop under control and also to form a flat end during the inversion operation. This is for the purpose of

The path drawn by the delivery end rises in a straight line, and also has a circular continuous arcuate line, Or various combinations of these.

Various guiding devices allow the pendulum and its delivery end to oscillate naturally with a circular delivery path. deflected from the riko motion. From that moment on, there is a deviation from the pendulum movement of nature. The pendulum's oscillation point can be moved vertically, or the oscillation radius of the sending end can be changed. Must be movable.

A fixed-angle delivery trajectory consisting of a mainly horizontal central portion and an arcuate terminal portion is desired; The arm provided on the circular bearing consists, for example, of a lower end, which lower end is attached to the upper part of the bearing on the pendulum side. This actuating part is connected to the lock shaft and thus pendulums in a generally horizontal path. During the period, the pendulum's oscillation point sinks/rises. The vibration point is located at a stop point or other The pendulum reaches a stopping point in its outermost region at any other stopping point. Furisen, which performs an upward movement in the area and a downward movement in the same area during the reversal operation. The arrangement of the arm attachment part relative to the circular bearing is such that the pendulum vibrates relative to the arm at this stage. For example, use a fork bearing or the like so that the The top of the pendulum connecting rod and the swing A spring is appropriately installed between the lever and the height position guide arm, which allows acceleration and deceleration. forces are kept partially parallel at both distal points of the pendulum.

The operation of the pendulum can also be guided, for example by a fixed guide, The guide is provided symmetrically with respect to the solid axis, and the 1,000 yen guide is provided along this axis. A wheel is attached to the bearing, or a sliding body is movably provided. delivery end The constant angle trajectory thus corresponds to the shape of the guide. Height of the guide above the delivery end is determined by the shape and mass size.

The oscillating points of the pendulum can alternately be at rest, while the sending end can be at the oscillating point. radially possible.

The invention is described below with reference to a number of preferred embodiments of the invention, as well as the accompanying drawings. Let's give a detailed explanation with reference to Figure 1; FIG. 1 is a schematic representation of pendulum motion in two preferred embodiments; The child motion shows constant velocity motion and motion with deceleration and acceleration speeds, while The sending end of the pendulum traces a circular path, (A), respectively after constant speed deceleration and It also depicts the motion of a pendulum with an accelerating speed, while on the other hand, it depicts the motion of a pendulum with a constant speed. The sending end moves at a constant height above the receiving conveyor, and the sending end moves at a constant height above the receiving conveyor, and the sending end moves in the deceleration and acceleration motion phases respectively. moves along an arcuate path (B).

FIG. 3 shows another preferred embodiment of the pendulum with associated drive and three different positions. shows the pendulum at

In Figure 1, case (A) is shown on the right side of Figure 1, and in this (A), the speed is constant. The pendulum during both the period of , and the period of deceleration and acceleration speed is around point P. The point P is stationary in this (A), and the sending end draws an arc and is oscillating. The rover is driven by a low speed chain using a guiding device. The connecting rod ■ is on the conveyor It is attached to the bearing and connected to the drive chain at point T, and connected to the pendulum mechanism at point KA. It will be done. Each point from 1 to 12 is marked in the drive chain, which allows points 1 and 12 to be marked. 7 indicates the center point of the pendulum, 4 and lO are the distal points of the pendulum, and 12 and 2 means that the T point of the connecting rod is at position 1, which together with 6 and 8 respectively indicate the limit of the constant speed region. , the pendulum is suspended at the vibration point P and the sending end position indicated by 1 (A). . When the connecting rod moves from 1 to 2 at a constant speed, the vibration point P remains stationary, so the delivery end forms an arc. When the pendulum moves from 2 to 4 and decelerates, the direction of movement changes at point 4, and 1 point 4. accelerates from point 6 to point 6 and moves from point 6 to point 7 while the delivery end moves in an arc of rise and fall. , the tightening on the pendulum may be more or less depending on the position of part KA with respect to drive unit HD. A symmetrical figure is formed. That is, 1 point 3 and 5, and 2 and 6 are each other. Slightly deflected. This can be seen in the rough diagram. The pendulum is approximately 24 cm at distal point 4 Rise. This is also clear from the figure drawn at a scale of 1/10, and the Forming controlled loops of the primary lamina at points. Sending end and receiving conveyor SA Due to the small distance between them, and due to the delivery speed and vibration speed of the delivery end, The delivered primary thin plate is quickly fixed to the base, and this base is also roughly The movement of the pendulum from point 0 7 to 1 seen in the figure is considered to be the reversal of the movement from point l to 7. It is not shown because it can be

The left side of Figure 1 shows the case (B), in which the pendulum has a constant speed period of The sending end of the middle pendulum operates at a constant height above the receiving conveyor, causing deceleration and acceleration. During the motion, the center point of the pendulum, 7, moves along a circular path. The moving point is at P', but while being moved to point 8, it sinks to point P, thus sending The edges move along the horizontal line 0 Deceleration phase from point 8 to 10 and acceleration from point 10 to 12 In the phase, the vibration point P is kept stationary, and the sending end is an arc, as can be seen from the diagram 0. uni, the receiving conveyor SR is located higher than in case (A), and this is due to the pendulum. This is because the vibration point of is higher than the center position in case (B).

The pendulum rises approximately 16 cm at its highest point. This position is as shown in the diagram. be. The looping of the thin plate is well controlled in this case, and it is This is because the distance to the base of the board is short, especially between points 7 and 8 and 12 and l. Furthermore, due to the synchronization between the delivery speed and vibration speed of the delivery end at these distances, It is from.

To operate the pendulum delivery end horizontally over most of its length, the pendulum For 50% of the child's oscillation, the oscillation point must move from Po to P point, that is. Special dimensions required. Two preferred embodiments of such a configuration are shown in FIG. Each figure in FIG. 3 is shown.

Figure f:t42 and Figure 3 show the pendulum part and related parts of the machine for producing slag cotton sheets. The receiving conveyor for the next thin plate is 1, and the associated pendulum hole The conveyor is 2, the two opposing conveyors are 2a and 2b, and the conduction at the delivery end is The rollers are designated 3a and 3b respectively.

The receiving conveyor is shown at 4, the drive mechanism is at 5, and the two wheels of the drive mechanism are at 5a. and 5b, and the connecting rod is shown as 6. Parts from 1 to 6 are shown in Figure 2 and at Taga position. They correspond to each of the figures in FIG. 3 and are designated by the same number.

In Figure 2, the ring that transmits the motion of the pendulum to the guide gear is shown as 7, and The axis of the wheels fixed to the child conveyor is along which the zero wheel 7 shown as 7a runs, and The guide for determining the constant angular trajectory at the end is indicated by 9, and the delivery end of the pendulum hole conveyor is indicated by 10. It is.

When producing slag cotton sheets, the second sheet is sent onto a receiving conveyor and further coated. It travels between the conveyors 2a and 2b, enters the pendulum mechanism 2, and comes out from the delivery end 1o. It will be done. - When the next thin plate is fed between the conduction rollers 3a and 3b, the pendulum swings back and forth. swing in the direction. When the connecting rod moves the distance #bl between the drive wheels 5a and 5b, the car 7 is subjected to constant velocity movement and at the same time actuates the flat part of the guide 9. This allows conduction The rollers 3a and 3b are connected to cover a distance Bl at a certain height above the receiving conveyor. When the rod moves on the circumference of the drive wheel by a length equal to distance #b2, the wheel 7 is above the guide 9. moving over the bent end, the sending end of the pendulum follows the corresponding arc over distance #B2 , the position of the guide 9 is determined by the desired kinematic geometry. pendulum vibration Point 22 is transformable along the line indicating the locus of the central pendulum motion, and is The receiving conveyor l is connected so that it can operate vertically according to the movement of the delivery end of the pendulum. It is mounted on the bearing by a knot.

FIG. 3 shows another preferred embodiment of the pendulum according to the invention, in which the lower end of the arm 20 is It is fixed on a bearing on the outside of the pendulum on the center line of vibration, and its upper end is placed on the pendulum. is mounted on the fork bearing provided at the bearing point 8 of the connecting rod 6. Bearing point 8 is on the arm It is provided to run within the fork 21 at the end. The pendulum's vibration point 22 is It is exchangeable vertically along the center line of its movement, and - the receiving conveyor of the next thin plate l , as in the previous case, at the joints so that they can follow the pendulum motion perpendicularly Therefore, it is mounted on the bearing. The connecting rod runs across the horizontal section between the drive wheels. When the pendulum is pulled into one angular position, the point of oscillation moves downward. , moves until it reaches the stopping point 23 at the bond point of the constant speed cycle, this stopping point is the vibration point. To prevent the pendulum from falling further, the pendulum is allowed to oscillate around the previously fixed oscillation point P. Be strong. During this deceleration movement, the tightening point 8 is displaced upward within the fork 21. , thus preventing the pendulum from rising along the arcuate line. Tong〈 During the acceleration phase, the pendulum swings downward and the delivery end lO traces a similar arc, while the tightening The plating point 8 is simultaneously displaced towards the bottom of the fork 21. A similar movement Repeated in opposite positions.

A spring is installed between the central axis and the arm 20 to prevent deceleration and acceleration caused by the vibration of the pendulum. It is beneficial to take out the pieces.

In the pendulum motion shown in each of the embodiments shown in FIGS. 2 and 3, the horizontal In particular, the nearly horizontal delivery motion coincides with a motion phase with constant velocity, and and the respective motions of sedimentation are consistent with the respective velocity phases of deceleration and acceleration. . The controlled constant angle trajectory of the delivery end deviates from the circular constant angle trajectory, but the constant speed b1 open at any point throughout the period or period of deceleration or acceleration motion b2. Of course adjusted to start.

As mentioned above, the deceleration and acceleration forces are smaller than in the methods used in the prior art. , and this is partly due to the upward movement on the delivery side, and partly due to the upward movement on the delivery side. This is caused by a small pendulum with a small mass.

By adding several different methods to the implementation described above, the It rises at a high level and has a constant speed during the movement phase of the central part of the movement. It is said that implementing the idea of the present invention of making a pendulum move is a rotation part. That is clear.
