Description Elastic plate roll removal support device Technical field

The present invention relates to an elastic plate winding / removing support device capable of winding / removing a large elastic plate having a large weight and a large area on a plate cylinder of a printing roll by saving labor and labor. Background art

As a device for forming a polymer or inorganic material used for electronic components such as a liquid crystal alignment film in a thin or thick film pattern, for example, an intaglio roll 16 having many ink cells, and filling the ink in the ink cells Fixing the ink supply device 20, the printing roll 14 on which the elastic plate 1 to which the ink of the intaglio roll 16 is transferred is wound on the plate cylinder, and the printing medium to which the ink of the printing port 14 is transferred There is a film forming apparatus consisting of a printing table to be filled and a doctor blade 19 for surely filling the ink cells of the intaglio roll 16 with ink (see FIG. 19). A first plate holder 2 and a second plate holder 3 are attached to both ends of the elastic plate 1. The plate cylinder of the printing roll 14 is provided with two first and second chuck portions 150, 15 at two locations for hooking and fixing the holes of the first plate holder 2 and the second plate holder 3. ing.

With the recent increase in size of electronic components, the size of the elastic plate also inevitably increases (for example, the size of the elastic plate is approximately lm in the winding direction, approximately 8 Ocm in the width direction, and the weight of the elastic plate 1). Taking into account 1. O kg and two plate holders, some have a total weight of about 3.4 kg.) When winding or removing the elastic plate 1 around the plate cylinder of the printing opening 14, a person lifts the first plate holder 2 of the elastic plate 1 and another person holds the second plate holder 3. It is necessary to hook and fix the second chuck portion 15 of the plate cylinder of the printing roll 14 and to rotate the printing roll 14 (hereinafter, the elastic plate causing such inconvenience is called “large elastic Version.)

Therefore, when the large elastic plate 1 is wound around the plate cylinder of the printing roll 14 in the film forming apparatus, at least two workers (hereinafter, a first worker and a second worker) are required. And ). Hereinafter, the work of winding and removing the conventional large elastic plate 1 will be described in detail.

First, the first worker climbs on the base 10 of the film forming apparatus, stands up with the first honoreder 2 attached to the large elastic plate 1, and suspends the second holder 3 and the large elastic plate 1 by gravity. Lower. While maintaining the suspended state, the first worker brings the second holder 3 close to the second chuck portion 15 formed on the plate cylinder of the printing roll 14. Next, the second operator hooks the second plate holder 3 on the second chuck portion 15 formed on the plate cylinder of the printing roll 14 with the hand of a second worker to fix the second plate holder 3. Next, the second worker, having confirmed the completion of the fixing, rotates the printing roll 14 at a low speed by the motor 14M, and gradually winds the large elastic plate 1 around the plate cylinder of the printing roll 14. At this time, while the large elastic plate 1 is wound on the plate cylinder of the printing port 14, the first worker holds the large plate 1 with the first plate holder 2 and the large elastic plate 1 raised. Apply pressure to the arm to maintain a certain level of tension on 1 and lean forward until the first plate holder 2 approaches the first chuck 1 ・ 50 formed on the plate cylinder of the printing roll 14. In this state, the first plate holder 2 and the large elastic plate 1 are kept lifted. Next, when the rotation of the printing roll 14 advances and the first plate holder 2 approaches the first chuck portion 150 formed on the plate cylinder of the printing roll 14, the second worker presses the printing roll 14. Is stopped, and the first plate holder 2 is hooked and fixed to the first chuck portion 150 formed on the plate cylinder of the printing roll 14 by the hand of the second worker. The first worker confirming the completion of the fixing releases the first edition holder 2. This completes the winding.

In addition, when removing the large elastic plate 1 from the plate cylinder of the printing roll 14, it must be performed by at least two people (hereinafter, referred to as a first worker and a second worker). First, the first worker climbs on the base 10 of the film forming apparatus and holds the first plate holder 2 attached to the large elastic plate 1 by leaning forward. The second operator removes the first plate holder 2 from the first chuck portion 150 formed on the plate cylinder of the printing roller 14. Next, the second worker, who has confirmed the removal, rotates the print roll 14 at a low speed by the motor 14M in a direction opposite to the above-described winding. At this time, the first worker lifts the first plate holder 2 so that the large elastic plate 1 does not hang down due to gravity and come into contact with the film forming apparatus. 1 The whole is peeled from the plate cylinder of the printing roll 14 Until the first plate holder 2 and the large elastic plate 1 are lifted. Next, when the entire large elastic plate 1 is peeled off from the plate cylinder of the print roll 14, the second worker stops the rotation of the print roll 14, and the second plate holder 3 is formed on the plate cylinder of the print roll 14. Remove it from the second check section 15 with the hand of a second worker. The first worker suspends the large elastic plate 1 and the plate holders 2 and 3 at both ends only by own force. This completes the removal.

The conventional technology has the following problems.

(1) Hold the first plate holder 2 of the large flexible plate 1 and lift it on the film forming apparatus, and hook the second plate holder 3 on the second chuck portion 15 of the printing roll 14 and fix it. It is labor intensive and very inefficient because it requires people and people separately.

(2) It is necessary to pull up the large elastic plate 1 so that a certain tension is applied to the large elastic plate 1 so that the large elastic plate 1 does not undulate until the large elastic plate 1 is completely wound. Since the first plate holder 1 and the first plate holder 2 are heavy, a heavy load is imposed on a person who holds the first plate holder 2 of the large elastic plate 1 and lifts it on the film forming apparatus. In addition, since the large elastic plate 1 has a large area and the first plate holder 2 is long, a person who lifts the large elastic plate 1 spreads his arms widely and holds the first plate holder 2. The feeling of weight of 1 plate holder 2 is further amplified.

(a) Due to this, unless careful work is performed in accordance with the prescribed manual, the large elastic plate 1 will drop onto the print rolls 14 and there is a danger that both the large elastic plate 1 and the film forming device will be damaged. Was.

(b) In addition, the first plate holder 2 is liable to shake, so that the first plate holder 2 cannot be kept horizontal at all times, and when the large elastic plate 1 is wound around the plate cylinder of the printing roll 14, a large size is required. It is difficult to lower the large elastic plate 1 substantially in synchronization with the rotation of the printing roll 14 while maintaining the tension applied to the elastic plate 1 uniformly and uniformly over the entire surface. Therefore, the large elastic plate 1 wound on the plate cylinder is wavy and crisp.

(3) Until the large elastic plate 1 is completely wound around the plate cylinder of the printing roll 14, the person must hold the first edition honoreder 2 from beginning to end. You will hold the large elastic plate 1 for a long time. Therefore, the dust and oil adhere to the large elastic plate 1 and the large elastic plate 1 is easily stained. (4) The first worker holding the first plate holder 2 and hanging the second plate holder 3 moves the large elastic plate 1 in parallel with the second plate holder 3 hanging, and moves the second plate holder 3 Is moved closer to the second chuck portion 15, but the large elastic plate 1, the first plate holder 2, and the second plate holder 3, which have a large weight, must be moved in parallel while bearing all the weights. Also, since the first plate holder 2 is held and supported directly above the print roll 14, the print roll 14 cannot stand stably because of obstruction. As described above, it is difficult to move the second plate holder 3 to an accurate position of the second chuck portion 15 due to the movement of a heavy object and a poor scaffold.

(Explanation of large elastic version)

The large elastic plate 1 as an example of the elastic plate will be described.

The large elastic plate 1 is a soft plate made of rubber, nylon resin, etc. There is a so-called elastic letterpress having a convex portion 17 formed in a desired pattern on the surface. Alternatively, an intaglio plate having a concave portion formed on the surface by a pattern or a planographic plate may be used.

The large elastic plate 1 has a rectangular shape with a winding direction of about 140 cm, a width direction of about 795 cm, and a weight of about 1.0 kg (2 plate holders are required to be 2. 4 kg) and one with a winding direction of about 1158 cm, width direction of about 93.5 cm, and weight of about 1.3 kg (2.8 kg with two plate holders).

The large elastic plate 1 has horizontally long plate holders attached to both ends. The plate holder that is held by being held by the holding unit 7 of the large-sized elastic plate winding / removing support device is the first plate holder 2, and the second chuck unit 1 formed first on the plate cylinder of the print roll 14 4 The second plate holder 3 is a plate holder that is hooked and fixed to a plurality of locking projections 15 a as an example of 5. As the first edition holder 2, there is one in which two kinds of holes are formed. An example of a plurality of rectangular support device holding holes 4 to be hooked by the holding portion 7 of the large elastic plate winding and removing support device, and a first chuck portion 150 formed on the plate cylinder of the printing roll 14 And a plurality of circular chuck holes 5 for hooking and fixing the plurality of locking projections 150a. The plurality of support device holding holes 4 and the plurality of chuck holes 5 are holes formed by arranging several at equal intervals in the longitudinal direction of the first plate holder 2 (see FIG. 4). The support device holding hole 4 may be formed at only one location in the center of the first plate holder 2 (see FIG. 10), or may be formed at two or more locations. In the case of only one location, the large elastic plate 1 is hung in a pendulum-like manner on the holding part 7, so that the free movement of the first plate holder 2 causes wrinkles and wavings to occur on the large elastic plate 1. This is effective because it can be wound around the plate cylinder of the print roll 14 in a well-balanced manner while absorbing. Since the second plate holder 3 is not held by the holding portion 7 of the large-sized flexible plate winding / unloading support device, a plurality of the second chuck portions 15 formed on the plate cylinder of the print roll 14 are provided. Only a plurality of circular chuck holes 5 for hooking and fixing by the locking projections 15a are formed side by side at equal intervals in the longitudinal direction (see FIG. 4). The large elastic plate 1 is wound on a plate cylinder of a cylindrical printing roll 14, printing ink is attached to the top of the convex portion 17, and the convex portion 17 comes into contact with the surface of the printing medium. In this way, the ink is transferred from the top of the convex portion 17 to the surface of the printing medium and printing is performed. The printing roll 14 on which the large elastic plate 1 is wound is, for example, a printing roll of a film forming apparatus. The film forming apparatus is an apparatus for forming a polymer or inorganic material used for electronic components such as a liquid crystal alignment film in a thin film or a thick film in a pattern, and includes an intaglio roll having a large number of ink cells, and an ink plate in the ink cells.

(Description of arm)

The arm portion 6 is a horizontally long member that can move up and down in parallel.

The reason why it is horizontally long is to hold only the end of the large elastic plate 1 in the width direction. In the end portion 6, several holding portions 7 are formed at equal intervals in the longitudinal direction at locations corresponding to the plurality of support device holding holes 4 of the first plate holder 2 of the large elastic plate 1. . The support device holding hole 4 may be formed at only one location in the center of the first plate holder 2. When the large elastic plate 1 is wound on the plate cylinder of the print roll 14, it can be moved up and down almost in synchronization with the rotation of the print roll 14 by the motor 14 M for the IJ roll. This is because when the large elastic plate is removed from the plate cylinder 14, the plate is raised substantially in synchronization with the rotation of the print roll 14 by the print roll motor 14 M. Fitting holes (not shown) may be formed at both ends of the arm 6 so as to fit the two rails 9 and move smoothly when moving up and down. The width of the arm 6 is preferably slightly wider than the width of the first plate holder 2 and the second plate holder 3 attached to the large elastic plate 1. This is to make it easy to apply uniform tension to the entire surface of the large elastic plate 1. Examples of the material of the arm 6 include a metal such as stainless steel and a resin material. Considering the strength for supporting the area and weight of the large elastic plate 1 and the lightness for lifting up to the arm 6, aluminum is preferable.

The arm 6 rotates around the longitudinal direction, or moves in the longitudinal direction of the arm 6. It may be one that slides linearly.

(Description of holding unit)

Each holding part 7 is a member formed on the arm part 6 for holding the first plate holder 2 of the large elastic plate 1. Examples of the holding unit 7 include a metal hook-shaped hook and a bar-shaped member provided with a notch at the tip. The hooks and the cutouts are provided so that the support device holding holes 4 of the first plate holder 2 do not easily slip off.

In order to suspend the large elastic plate 1 in a well-balanced manner in the left-right direction, the same number of the holding portions 7 may be formed on the arm portion 6 in a symmetrical manner. The holding unit 7 may be a magnetic type or a vacuum suction type. The holding section 7 is not limited to a plurality of holding sections, and may be provided only at one location.

(Description of drive unit)

The drive unit 800 is a member that translates the arm unit 6 up and down along the two rails 9. The drive unit 800 can move the arm unit 6 while maintaining the tension applied to the large elastic plate 1 constant. The drive unit 800 includes, for example, two rails 9 erected on the base 10 of the film forming apparatus at intervals about the length of the rotation axis of the print roll 14, and two Air cylinder 11 fixed to the base of one of the rails 9 and two chambers divided by the piston in the air cylinder 11 1, that is, the upper pressurization chamber and the lower pressurization The air cylinder drive controller 900 controls the operation of the air cylinder 11 by controlling the intake and exhaust operations of the chambers. Some parts are in contact with the lower surface 18 of the part 6 (see FIGS. 4 to 6). Since both ends of the arm 6 are movably fitted to the two rails 9 through the fitting holes (not shown), when the push rod 12 of the air cylinder 11 is protruded, the arm 6 is pushed up along the two rails 9 and rises to near the top of the two rails 9. The air in the lower pressurizing chamber in the air cylinder 11 is exhausted by the air cylinder drive controller 900, and the arm 6 is lowered again to the base of the two rails 9 due to the weight of the arm 6. Will come. The control of the descent speed of the arm 6 The air cylinder drive control unit 900 controls the amount of air exhausted from each pressurizing chamber in the air cylinder 11 per hour. As an alternative to the hair cylinder 111 of the drive unit 800, a drive device that moves the arm unit 6 by hydraulic pressure, water pressure, or a motor may be used.

Further, at least one of the two rails 9 may be provided with a linear guide 13 for guiding the arm 6 so as to be able to perform a straight-line operation during a parallel movement along the up-down direction of the arm 6. .

(Simultaneous lifting and lowering operation of the arm unit 6) When the arm unit 6 winds the large elastic plate 1 around the plate of the print roll 14 while keeping the tension applied to the large elastic plate 1 constant, the print roll motor When descending substantially in synchronization with the rotation of the print roll 14 by 14 M, when removing the elastic plate from the plate cylinder of the print roll 14, the rotation of the print roll 14 by the motor 14 M It is possible to rise in synchronization. The mechanism for lowering and rising substantially synchronously with the rotation of the printing roll 14 while maintaining the tension applied to the large elastic plate 1 constant is as follows. As described above, an example in which the air cylinder 11 is used as the drive unit 800 and the tip of the push rod 12 is in contact with the lower surface 18 of the arm unit 6 will be described.

(In case of lowering arm)

A large elastic plate is attached to the plural holding parts 7 of the arm part 6 which has been pushed up by the protrusion of the extrusion cylinder 12 of the air cylinder 11 by the air cylinder drive controller 900 and raised to near the top of the rail 9. The first plate holder 2 holds a plurality of supporting devices 4 of the first plate holder 2 (see FIG. 4), while the second plate holder 3 of the large elastic plate 1 is the second plate of the printing roll 14 It is hooked on the chuck part 15 to be fixed. After that, when the printing roll 14 is rotated at a low speed by a motor 14M in the direction in which the large elastic plate 1 is wound, the large elastic plate 1 is pulled downward, but the printing roll motor 1 of the printing roll 14 is pulled down. Calculation unit 10000 based on 4M rotation speed data Air cylinder

1 Calculate the volume of air to be exhausted from the lower calo-pressure chamber in 1 and supply the calculated volume of air to the inside of the air cylinder 11 by the air cylinder drive control device 900 of the drive unit 800. The arm 6 is properly adjusted in synchronization with the rotation of the print roll 14 while maintaining the tension applied to the large elastic plate 1 at a constant level. Start descending at a reasonable speed (see Figure 5). The value of the tension applied to the large elastic plate 1 is, for example, one having a winding direction of about 140 cm, a width direction of about 795 cm, and a weight of about 1.0 kg (with two plate holders). (2.4 kg) with the second plate holder 3 fixed to the printing roll 14, the tip of the panel scale was hung on the second plate holder 3 and suspended, and the printing roll 14 was rotated at a low speed for measurement. Sometimes it is a constant value between 2 and 5 kg.

When the rotation of the print roll 14 is stopped, the lowering of the arm 6 also stops. By completely exhausting the air in the lower pressurizing chamber in the air cylinder 11 by the air cylinder drive control unit 900, the arm unit 6 descends to a predetermined position (see FIG. 6).

(In the case of raising the arm)

An arm 6 located at the base of the rail 9 with the large elastic plate 1 wound around the printing roll 14 on the plate and the second plate holder 3 fixed to the second chuck 15 of the plate cylinder. The first plate holder 2 of the large elastic plate 1 is held by the holding portion 7 of the first plate. After that, when the print roll 14 is rotated at a low speed by the print roll motor 14M in the direction to remove the large elastic plate 1, the air cylinder drive control is performed with the amount of air calculated based on the rotation speed of the print roll 14. By gradually press-fitting into the caropressure chamber below the air cylinder 11 of the drive unit 800 by the device 900, the arm unit 6 is rotated at an appropriate speed in synchronization with the rotation of the print roll 14. Start climbing. For this reason, the large-sized transparent plate 1 is lifted up without sagging on the base 10 of the film forming apparatus. When the rotation of the print roll 14 is stopped, the lifting of the arm 6 is also stopped. By further pressurizing the air into the air cylinder 11 by the air cylinder drive controller 900, the arm 6 rises to the top of the two rails 9.

An example of a case where a single first worker removes and winds a large elastic plate using the large elastic plate winding / unmounting support device of the first embodiment will be described.

(In the case of winding)

The first worker hooks the plurality of support device holding holes 4 of the first plate holder 2 of the large elastic plate 1 with the plurality of holding portions 7 of the arm unit 6 of the support device, and lifts the second plate holder 3 by gravity. (See Fig. 4). In the suspended state, the second plate holder 3 holds the printing roll 14 plate It comes to the front of the second chuck part 15 formed on the body. This is because if the large elastic plate 1 having a predetermined area is suspended, the second plate holder 3 can be automatically adjusted to the height of the arm 6.

Next, the first worker inserts the plurality of chuck holes 5 of the second plate holder 3 into the plurality of locking projections 15 a of the second chuck portion 15 formed on the plate cylinder of the printing roll 14 to perform the first work. Hook with the person's hand and fix it. Next, the first worker, having confirmed that the fixing is completed, rotates the printing roll 14 at a low speed with the motor 14M, and gradually winds the large elastic plate 1 around the plate cylinder of the printing roll 14. The arm 6 holding the first plate holder 2 is provided with an air cylinder based on the air volume in the air cylinder 11 calculated by the arithmetic unit 100 based on the rotation speed data of the printing roll 14. By controlling the amount of air exhausted from the caropressure chamber below the air cylinder 11 with the drive control unit 900, the first version of the large elastic plate 1 is automatically maintained while maintaining appropriate tension. The descent is continued until the holder 2 approaches the first chuck portion 150 formed on the plate cylinder of the printing roller 14. Next, when the first plate holder 2 of the large elastic plate 1 approaches the first chuck portion 150 formed on the plate cylinder of the printing roll 14, the first worker stops the motor 14M and performs printing. Stop the rotation of the roll 14, remove the multiple support device holding holes 4 of the first plate holder 2 from the multiple holding units 7 of the support device, and print the multiple chuck holes 5 of the first plate holder 2. The plurality of locking projections 150a of the first chuck portion 150 formed on the plate cylinder of the roll 14 are hooked and fixed by the first worker's hand. This completes the winding of the printing roll 14 of the large flexible plate 1 around the plate.

The arm unit 6 of the support device stands by as it is in preparation for the removal of the large elastic plate 1 until the film forming operation is completed.

(In case of removal)

The first operator prints the plurality of chuck holes 5 of the first plate holder 2 of the large elastic plate 1 The plurality of locking projections 15 of the first chuck portion 15 formed on the plate cylinder of the port 14 Remove from a and hook the plurality of supporting device holding holes 4 of the first edition holder 2 with the plurality of holding portions 7 of the supporting device.

Next, the first worker, having confirmed the fixation, rotates the print roll 14 at a low speed by the motor 14M in the opposite direction to the above-described winding. Arm holding first edition holder 2 6 is an air cylinder drive controller 900, which is based on the amount of pressurized air in the air cylinder 11 calculated by the arithmetic unit 100 based on the data of the number of rotations of the print roll 14 (1) By controlling the amount of air injected into the lower pressurization chamber (1), the ascent continues automatically while maintaining the appropriate tension, causing the large elastic plate (1) to fall down due to gravity and form a film forming device. Never touch.

Next, with the entire large elastic plate 1 peeled off from the plate cylinder of the printing roll 14, the first operator stops the motor 14 Μ to stop the rotation of the printing roll 14, and the second plate holder 13 The plurality of chuck holes 5 are removed from the plurality of locking projections 15 a of the second chuck portion 15 formed on the plate cylinder of the printing port 14 by a first operator's hand. This completes the removal of the printing roller 14 of the large elastic plate 1 from the plate cylinder.

As a result, the large elastic plate 1 is suspended by the support device, and the plurality of support device holding holes 4 of the large elastic plate 1 are removed from the plurality of holding portions 7 of the arm portion 6 to form another large elastic plate. Replace with 1.

The large-sized elastic plate winding / removing support device according to the first embodiment of the present invention has the following configuration, and thus has the following effects.

(1) The large elastic plate 1 can be held by the large elastic plate winding / removing support device while the print roll 14 is wound on or removed from the plate cylinder on the film forming apparatus. There is no need for a person to lift the individual version 1, which is very labor-saving and very efficient.

(2) Even if the large elastic plate 1 and the plate holders 2 and 3 are heavy, the large elastic plate 1 can be held by the large elastic plate winding / unloading support device. No load is applied.

(a) For this reason, the large elastic plate 1 does not drop onto the printing roll 14, and there is no danger that both the large elastic plate 1 and the film forming apparatus are exposed.

(b) In addition, since the first plate holder 2 is mechanically lowered by the large elastic plate winding and removing support device, it is difficult for the large elastic plate 1 to shake, and the first plate holder 1 is always kept horizontal. When the large elastic plate 1 is wound around the plate cylinder of the printing roll 14, the tension applied to the large elastic plate 1 can be maintained at a uniform and constant value over the entire surface. Therefore, the large elastic plate 1 may be wound around the plate cylinder in a wavy state. Nare,

(3) The large elastic plate 1 can be held by the large elastic plate winding / unloading support device until the large elastic plate 1 is completely wound around the plate cylinder of the printing rolls 14. Since there is no need to hold it with human hands, it is not necessary to hold the large elastic plate 1 for a long time with hands that have garbage, oil, or sweat. Therefore, the dust and oil do not adhere to the large elastic plate 1 and the large elastic plate 1 does not easily become dirty.

(Second embodiment)

Hereinafter, the second embodiment of the present invention will be described in detail with reference to FIGS. 7 to 9 and FIG.

The large elastic plate winding and removing support device according to the second embodiment of the present invention is shown in FIGS.

As shown in FIG. 18, the second plate holder 3 of the first plate holder 2 at one end of the elastic plate 1 and the second plate holder 3 at the other end is mounted on the plate cylinder of the printing roll 14. An elastic plate winding / removing support device used when attaching or detaching the first plate holder 2 of the elastic plate 1 to or from the plate cylinder of the printing roll 14, wherein the first plate holder of the elastic plate 1 is provided. The holding unit 107 holding the holding plate 107 is held substantially in synchronization with the rotation of the printing roll 14 in the elastic plate winding direction while maintaining the tension applied to the elastic plate 1 constant. While the print roll 14 is approached to the plate cylinder, the holding portion 107 is moved substantially in synchronization with the rotation of the print roll 14 in the unwinding direction of the elastic plate, and the plate 107 of the print roll 14 is rotated. The elastic plate moving device 810, 910, 1010, which is separated from the cylinder, is located above the printing roll 14 above. A base plate 109 which is attached to the base plate 109, and a rotary arm unit 100 which is rotatable about one end attached to the base plate 109 and the other end of which is rotatably mounted with the holding unit 107. And 6. As an example, the elastic plate moving device 8100, 910, 11010 includes a driving unit 8110 for controlling the rotation of the rotating arm unit 106, When the elastic plate 1 is wound around the plate cylinder, the printing unit 14 rotates the printing roll 14 in the elastic plate winding direction by the drive unit 810 while maintaining the tension applied to the elastic plate 1 constant. Approximately in synchronization, the other end of the rotary arm 106 is rotated down while rotating, and the holding unit 107 is brought closer to the plate cylinder of the print roll 14, and the print roll 14 is rotated. So that the elastic plate 1 can be wound on the plate cylinder of On the other hand, when removing the elastic plate 1 from the plate cylinder of the printing roll 14, the drive unit 8 10 is used to substantially synchronize with the rotation of the printing roll 14 in the unwinding direction of the elastic plate. The other end of the rotating arm 106 is raised while rotating, and the holding unit 107 is separated from the plate cylinder of the printing roller 14, and the holding unit 107 is separated from the plate cylinder of the printing roll 14. Help elastic plate 1 to be removed.

(Explanation of large elastic version)

The large elastic plate 1 used in the second and subsequent embodiments is the same as in the first embodiment.

That is, the large elastic plate 1 has a horizontally long plate holder attached to both ends. The plate holder that is hooked and held by the holding portion 107 of the large elastic plate winding and removal assisting device is the first plate holder 2, and the second chuck portion 15 formed on the plate cylinder of the printing roll 14 The plate holder to be hooked and fixed to the plurality of locking projections 15a is referred to as a second plate holder 3. As the first edition holder 2, there is one in which two kinds of holes are formed. A plurality of rectangular support holes 4 for holding the support device to be hooked by the holding portion 107 of the large elastic plate winding / removing support device, and a plurality of first chuck portions 150 formed on the plate cylinder of the print roll 14. A plurality of circular chuck holes 5 for hooking and fixing the locking projections 150a. The support device holding holes 4 and the plurality of chuck holes 5 are holes formed at regular intervals in the longitudinal direction of the first plate holder 2. The support device holding hole 4 may be formed at only one location in the center of the first plate holder 2 (see FIG. 10), or may be formed at two or more locations. If only one part, large elastic plate

1 is suspended in a pendulum-like manner on the holding portion 107, so that the free shaking of the first plate holder 2 absorbs wrinkles and waving that is likely to occur on the large elastic plate 1, and the printing roller 14 It is effective because it can be wound around the plate cylinder in a well-balanced manner. Since the second plate holder 3 is not held by the holding portion 107 of the large elastic plate winding / unloading support device, a plurality of second chuck portions 15 formed on the plate cylinder of the printing roll 14 are provided. Only a plurality of circular chuck holes 5 for hooking and fixing by the locking projections 15a are formed side by side at equal intervals in the longitudinal direction (see FIG. 10). The large elastic plate 1 is wound around a plate cylinder of a cylindrical printing roll 14, a printing ink is attached to the top of the convex portion 17, and a convex portion 17 is formed on the surface of the printing medium. Is brought into contact with the projection 1 Ink is transferred from the top of 7 to the surface of the printing medium and printed.

(Description of base plate)

The base plate 109 is located above the print roll 14.

The base plate 109 may be extended downward from the ceiling beam of the factory where the flum forming device is installed. Alternatively, the base may be installed at a location remote from the film forming apparatus, and may be extended above the printing roll 14 from there.

In the first modified example of the second embodiment shown in FIG. 10, two base plates 109 are installed at intervals larger than the width of the first plate holder 2 in the longitudinal direction. ing. This is for mounting each of the two rotating arms 106. The material of the base plate 109 is aluminum or the like. Rotating arm part 106 and large elastic plate

Since it is necessary to support heavy objects such as the first plate holder and the second plate holder, those having high rigidity are preferable.

(Explanation of movable turn roll)

As shown in Fig. 15, each base plate 109 forms an angle in the tension direction of the large elastic plate 1 during rotation of the rotary arm 106 (in other words, the large elastic plate 1 1) A movable turn roll 21 for tilting the large elastic plate 1 along the tangential direction of the plate cylinder where it is wound around the plate cylinder of 4) is attached to the end of a rod 2 2 extending from the base plate 109. It may be installed. By installing the movable turn roll 21, from the first plate holder 2 (that is, the tip of the rotary arm 106) to the movable turn roll 21, according to the rotation angle of the rotary arm 106. The tension direction of the large elastic plate 1 from the movable turn roll 21 to the second plate holder 3 can be made different from the tension direction of the large elastic plate 1.

In the second modification of the second embodiment shown in FIG. 15, the movable turn roll 21 is installed at the tip of a rod 22 extending from the base plate 109, and the large elastic plate 1 is moved to the right. It is pressing in the direction.

In the series of processes in Fig. 16A, Fig. 16B, and Fig. 16C, as shown in Fig. 16A to Fig. 16C, the pressing force of the movable turn roll 21 on the large elastic plate 1 is reduced. The angle 0 1, Θ 2, and Θ 3 formed by the movable arm 6 and the large elastic plate 1 are always about irrespective of the rotating state of the movable turn roll 2 1 90 degrees can be maintained. In this manner, the tensions t1, t2, and t3 applied to the large elastic plate 1 can be kept almost constant at all times. Therefore, the large elastic plate can be applied to the plate cylinder of the print roll 14 with a constant tension. There is an advantage that version 1 can be wound.

In addition, by installing the movable turn roll 21 so as to reach the lower right of the rotating arm 106, it is possible to prevent the rotating arm 106 from erroneously turning counterclockwise.

(Description of rotating arm)

Each rotating arm 106 is rotatable about a rotating shaft 113 attached to a base plate 109.

The material of each rotary arm 106 is preferably a lightweight and highly rigid material such as aluminum. This is because the movement of each rotary arm 106 can be performed by a low-power drive source.

The rotating shaft 113 of each rotating arm 106 with respect to the base plate 109 can be formed at any position in the longitudinal direction or width direction of the rotating arm 106. Suck

(The size of ^ of the printing roll 14 and the length of the base plate 109) may fluctuate. Therefore, the turning radius of the rotating arm 106 is adjusted to form the first plate holder 2 to be formed. Is also required to change the circular orbit.

The rotation of the two rotating arms 106 is controlled not by free rotation but by two air cylinders 111 and a panel. The reason for this control is to wrap the plate cylinder of the printing port 14 without undulating, and to prevent the large elastic plate 1 from unnecessarily loosening and coming into contact with the adjacent machine or the ground. It can also be controlled to keep the tension of the large elastic plate 1 constant.

Since the rotary arm 106 rotates, the large elastic plate 1 can be moved not only vertically but also horizontally.

Therefore, when the second plate holder 3 is fixed to the second chuck portion 15, the work can be performed safely without worrying about the weight and the scaffold of the large elastic plate 1. Further, the second plate holder 3 can be automatically moved to the vicinity of the second chuck portion 15. For this reason, the distance for manually moving the second edition holder 3 is completely unnecessary. Or, if necessary, it is very short and efficient.

Further, when fixing the first plate holder 2 to the first chuck portion 150, the first plate holder 2 can be moved to a position close to the first chuck portion 150. For this reason, the distance for manually moving the first plate holder 2 is not required at all, or even if necessary, it is extremely short and the efficiency is high.

In the first modified example of the second embodiment shown in FIG. 10, the rotating arm portion 106 is composed of two rotating arm portion main bodies 61 and 62 and a connecting member 60 connecting them. I have. The two rotating arm unit main bodies 61 and 62 are rotatably attached to the two base plates 109, respectively. At a substantially central portion of the connecting member 60, a holding portion 107 described later is rotatably attached to the connecting member 60.

(Description of holding unit)

In FIG. 10, the holding portion 107 is a member rotatably attached to the connecting member 60 to hold the first plate holder 2 of the large elastic plate 1. Examples of the holding portion 107 include a metal hook-shaped hooking portion 70 and a bar-shaped member provided with a notch at the tip thereof. The hooks and the notches are provided so that the support device holding holes 4 of the first plate holder 2 do not easily slip off. The hook portion may be an immovable type, or may be a movable type that is moved by an air cylinder or the like and tightens the inner wall of the support device holding hole 4 of the first plate holder 2 of the large elastic plate 1. The holding portion 107 may be formed at only one portion at the center portion, or may be formed at two or more portions at intervals.

Since the holding portion 107 is rotatably attached to the connecting member 60, the large elastic plate 1 and the first plate holder 2 are always connected regardless of the rotation angle of the rotating arm portion 106. They can be parallel (see Figure 7, Figure 8, Figure 9, Figure 15).

Although two or more hook portions 70 of the holding portion 107 may be attached, in the first modification of the second embodiment of FIG. 10, the hook portions 70 of the holding portion 107 are 2 It is attached to only one central part of the connecting member 60 that connects the two rotating arm bodies 61 and 62. If the large elastic plate 1 is free to oscillate by setting the holding part 107 at one place, the distortion when the large elastic plate 1 is wound is absorbed by the free sway of the large elastic plate 1 and printed. This is because the large elastic plate 1 can be wound around the plate cylinder of the roll 14 without generation of a seal. The holding portion 107 may be of a magnetic type or a vacuum suction type.

(Description of drive unit)

The drive section 8 10 controls the rotation of the rotary arm section 10 6. The driving section 8100 can rotate while maintaining the tension applied to the large elastic plate 1 constant. As the driving unit 8110, the two chambers divided by the pistons in the two air cylinders 111, that is, the pressurizing chamber on the rotating shaft 113C side and the rotating shaft 113C side By controlling the intake and exhaust operations of the opposite side of the caropressure chamber and synchronizing and exhausting the air, the two push rods 11 and 12 are projected or retracted in synchronization. The rotation speeds of the two rotating arms 106 are controlled by the pressure chamber on the rotating shaft 1 13 C side of the two air cylinders 1 11 and the pressure chamber on the opposite side of the rotating shaft 1 13 C side. This is done by controlling the amount of air per hour. The driving unit 8100 may be configured to rotate the rotating arm unit 106 by hydraulic pressure, hydraulic pressure, or a motor.

In the first modification of the second embodiment shown in FIGS. 11 to 13, the rotation of the two rotating arms 106 is controlled using two air cylinders 111. The tip of the extrusion port 1 1 2 of each air cylinder 1 1 1 is free to rotate with respect to the left ^ f rule overhanging section in Fig. 11 of inverted L shape of each rotating arm section 106. And the lower end of the body of each air cylinder 1 11 is mounted so as to rotate with respect to the base plate 109. That is, the holding portion 107 holding the first plate holder 2 is at the upper end position. As shown in Fig. 11, the lower end of the body of each air cylinder 1 11 1 is attached to the base plate 109 so that it can be rotated. The lower end is located at the position where the rotating shafts 1 1 3 る rotatably mounted on the base plate 1 09 are aligned side by side, and the longitudinal direction of each rotating arm 106 and the air cylinder 1 1 1 So that the tip of the extrusion port 1 1 2 of the air cylinder 1 1 1 is almost parallel to the inverted L-shaped figure 11 of the rotating arm 106. It is rotatably mounted on the side overhang with the rotating shaft 1 13 B. When the protruding amount of the two push rods 1 1 and 2 is small, the connecting members 60 are attached to the two rotating arms 106. (See Fig. 11) If the protrusions of the two push rods 1 1 2 are increased, the two rotating arms 106 will move to the rotating shaft 1 1. The connection material 60 is taken around 3 The attached end rotates to the right (see Figure 12). At the time of FIG. 12, the protrusion amount of the two extrusion ports 1 and 12 is almost the maximum. If the protrusion amount of the two push rods 1 12 is made smaller than the maximum protrusion amount, the two rotating arms 106 will be further attached at one end where the connecting member 60 is mounted around the rotating shaft 113. Turn to the right (see Figure 13). FIG. 13 shows a state where the state of FIG. 11 is rotated by 180 ° or more through the state of FIG. 12. By increasing and then decreasing the amount of protrusion of the two push rods 11, the state of FIG. 13 returns to the state of FIG. 11 via the state of FIG. 12.

On the other hand, in the third modified example of the second embodiment shown in FIGS. 17 to 18, the front view is the same as FIG. 10, but the lower end of the main body of the two air cylinders 11 and the two bases This shows a case in which the position of the rotating shaft 113C connecting the plate 109 is changed to a vertical position instead of a horizontal position as shown in FIG. That is, as shown in FIG. 17 in which the holding portion 107 holding the first plate holder 2 is located at the upper end position, the lower end of the body of each air cylinder 111 rotates to the base plate 109. The lower end of each rotary arm 106 is mounted on the base plate 109 so that it can be mounted on the base plate 109, above the rotary shaft 113C that can be mounted. The tip of the extrusion port 1 1 2 of the air cylinder 1 1 1 is inverted L-shaped with the rotating arm 1 1 6 so that the longitudinal direction of the 106 and the longitudinal direction of the air cylinder 1 1 1 1 intersect. It is rotatably mounted on the left overhang in Fig. 11 with the rotating shaft 113B. Further, in the third modified example of the second embodiment, the protrusion amounts of the two push rods 111 of the two air cylinders 111 are controlled without particularly controlling the exhaust or press-in amounts. The rotation force of the print roll 14 is transmitted through the large elastic plate 1 to rotate the two rotation arms 106 so that the two air cylinders 1 1 1 The amount of protrusion of the two extrusion ports 112 may be reduced while the air in the pressurized chamber on the rotating shaft 113C side is compressed. In this case, it is not necessary to control the intake and exhaust operations of the two air cylinders 111 from the outside, and the structure is simplified. In this example, when the protruding amount of the two push rods 11 and 12 is large, the two rotating arms 106 are positioned with the one end where the connecting member 60 is attached facing upward. See 17). Fig. 17 Large elastic plate winding of printing roll 14 from the state of 7 When the tensile force due to the rotational force in the mounting direction is transmitted to the two rotating arms 106 via the large elastic plate 1, the two rotating arms 106 are connected around the rotating shaft 113A, respectively. Each end where the material 60 is attached is rotated clockwise to the right, and the air in the caropressure chamber on the rotating shaft 1 13 C side of the two air cylinders 1 1 1 is compressed, and the two The protrusion of the push rod 1 12 becomes smaller (see Fig. 18). At point B in Fig. 18, the protrusion of the two extrusion ports 1 1 and 2 is minimal. When the tensile force acting on the large elastic plate 1 decreases due to the rotation of the printing roll 14 in the direction of removing the large elastic plate from the state shown in Fig. 18, the rotation shaft 1 1 3 C side of the two air cylinders 1 1 1 decreases. The air compressed in the pressurized chamber of the refrigeration chamber tries to return to the original state, and conversely, by continuing to increase the protruding amount of the two extrusion rods 11, the state of FIG. I will return to the state. As described above, the amount of protrusion of the push rods 1 1 2 of the two air cylinders 1 1 1 can be adjusted by rotating the print rolls 14 transmitted via the large elastic plate 1 without any external control operation. It can be made to fluctuate by the force and the restoring force of the air compressed in the pressurizing chamber on the C side of the rotating shaft in the two air cylinders. The air supply / exhaust operation of the two air cylinders 11 can also be controlled by the air cylinder drive control device 9 10 of the drive unit 8 10 so as to vary independently of the rotational force of the air cylinder. In FIGS. 17 to 18, if there is no rotational force of the print port 14, the state automatically returns to the state of FIG. 11. This is because a force is always applied to the air cylinder 111 in the direction in which the pushing rod 112 protrudes.

In the first modified example of the second embodiment shown in FIGS. 11 to 14, a force in which the protrusion amount of the tip of the push rod 1 12 of the air cylinder 11 changes from large to small to large is shown in FIG. In the third modified example of the second embodiment, the one-way operation is performed from large to small.

(Rotating operation of the rotating arm)

Rotating arm 1 0 6 force When winding the large elastic plate 1 around the plate of the printing roll 14, it is almost synchronized with the rotation of the print roll 14 while maintaining the tension on the large elastic plate 1 constant. When the elastic plate 1 is removed from the plate cylinder of the print roll 14, it is possible to rise while rotating substantially in synchronization with the rotation of the print roll 14. When the operator removes and winds up the large elastic plate by himself while lowering or raising it while rotating the print roll 14 substantially in synchronization with the rotation of the print roll 14 while maintaining the tension applied to the large elastic plate 1 constant. An example will be described.

(In the case of winding)

The operator adjusts the amount of protrusion of the extrusion ports 1 1 2 of the two air cylinders 1 1 1, and moves the two rotating arms 106 to the position at 12 o'clock in FIG. Stop) by rotating it slightly clockwise (clockwise) from The support device holding hole 4 of the first plate holder 2 of the large elastic plate 1 is hooked and fixed to the hook 70 of the holding portion 107 of the rotary arm 106, and the second plate holder 3 is gravity-fixed. (See Fig. 7). By rotating the two rotating arm sections 106 clockwise (clockwise) in FIG. 7, the holding section 107 of each rotating arm section moves rightward and downward in FIG. From the vertical position along 109, at the maximum left and right about the length of each rotating arm 106, and from the rotation axis 113 of each rotating arm 106, The first plate holder 2 can be hung on the rotating arm 106 at a position approximately up and down the length of the rotating arm 106 so that it can be suspended safely and securely with little force. The second plate holder 3 can be fixed to or removed from the locking projection 15a of the second chuck portion 15.

Since the holding portion 107 is rotatably attached to the connecting member 60, the first plate holder 2 and the large elastic plate 1 can be rotated no matter how the rotating arm portion 106 rotates. Is a parallel relationship according to the direction of the tension applied to the large elastic plate 1 without excessive bending (in other words, the tension is applied to the large elastic plate 1 along the tangential direction of the plate cylinder of the printing roll 14). (When the large elastic plate 1 is inclined along the tangential direction of the plate cylinder, it can be maintained at all times.)

Next, the worker who has confirmed that the holding portion 107 of the rotating arm portion 106 of the first plate holder 2 has been hooked on the hook portion 70 of the first plate holder 2, pushes the two air cylinders 1 1 1 out of the pushing rod 1 1. Adjust the protruding amount of 2 and synchronize the two rotating arms 106 to the left (counterclockwise) in Fig. 7 to rotate the suspended second plate holder 2 in the horizontal direction. For example, the printing roll 14 is moved in the horizontal direction to approach the locking projection 15a of the second chuck portion 15 of the printing roll 14 (see FIG. 14). The operator lifted the second edition holder 3 It is not necessary to move it horizontally, and the chuck hole 5 of the second plate holder 3 is inserted into the locking projection 15 a of the second chuck part 15 formed on the plate cylinder of the print roll 14 by hand or magnet. It only needs to be hooked and fixed.

Next, after confirming that the second chuck 15 of the second plate holder 3 has been fixed to the locking projection 15a, the operator drives the motor 14M to move the printing roll 14 to the motor 14M. And slowly rotate the large elastic plate 1 around the plate cylinder of the print roll 14. The two rotating arms 106 holding the first edition holder 2 are calculated and calculated by the arithmetic unit 100 based on the data of the rotation speed of the motor 14 M of the printing roll 14. Of air with the volume reduced is gradually exhausted from the pressurized chamber on the opposite side of the rotating shaft 1 13 C side of the two air cylinders 1 11 by the air cylinder drive control device 9 10 of the drive unit 8 10 As a result, while automatically maintaining an appropriate tension, the first plate holder 2 of the large elastic plate 1 is rotated until it approaches the first chuck portion 150 formed on the plate cylinder of the printing roll 14. Continue descending (see Figures 8 and 14). The tension value applied to the large elastic plate 1 is, for example, about 104 O mm along the winding direction, about 795 mm along the Ψΐ direction, and about 1.0 O in weight. With the 2nd plate holder 3 of 2 kg (2.4 kg with 2 plate holders) fixed to the printing port 1 4, the tip of the panel scale is hooked on the 2nd plate holder 3 for hanging printing. When roll 14 is rotated at low speed and measured, it is a constant value of 2 to 5 kg. When the rotation of the motor 14 M of the print roll 14 is stopped, the lowering of the rotating arm 106 is also stopped.

Next, when the rotation of the two rotating arms 106 advances, and the first plate holder 1 2 of the large elastic plate 1 approaches the first chuck portion 150 formed on the plate cylinder of the printing roll 14, The operator stops the rotation of the motor 14 M of the printing roll 14, removes the support device holding hole 4 of the first plate holder 2 from the holding device 107 of the support device, and checks the first plate holder 2. The holes 5 are hooked and fixed to the locking projections 150a of the first chuck portion 150 formed on the plate cylinder of the printing roll 14 (see FIG. 9). In FIG. 13, the holding member (not shown) of the rotating arm portion 106 has reached further leftward than immediately below the base plate 109. The first plate holder 2 is moved to the left from the vertical position of the base plate 109 by the length of the maximum rotating arm 106 by rotating the rotating arm 106 right. It can be securely and securely hooked and fixed with little force.

This completes the winding of the printing roll 14 of the large elastic plate 1 around the plate cylinder. (In case of removal)

The operator removes the chuck hole 5 of the first plate holder 2 of the large elastic plate 1 from the locking projection 15 of the first chuck portion 150 formed on the plate cylinder of the printing roll 14, and removes it. The support device holding hole 4 of the first edition holder 2 is hooked on the holding portion 107 of the rotary arm 106 of the support device.

Next, the operator confirming the fixation drives the motor 14M in a direction opposite to the direction of the above-described winding when the print roll 14 is rotated to rotate the print roll 14 at a low speed. First edition holder

The two rotating arms 106 holding the 2 are mounted on the air based on the air press-in amount calculated by the arithmetic unit 110 based on the rotation speed data of the motor 14 M of the printing roller 14. The cylinder drive controller 9 10 automatically controls the amount of air injected into the pressurizing chamber on the opposite side of the rotating shaft 1 1 3 C side of the air cylinder 1 1 1 to maintain an appropriate tension automatically. As it continues to rise, the large elastic plate 1 does not hang down due to gravity and contact the film forming device or the ground.

Next, with the entire large elastic plate 1 peeled off from the plate cylinder of the print roll 14, the operator stops the rotation of the motor 14 M of the print roll 14 and checks the second plate holder 3. The hole 5 is removed from the locking projection 15 a of the second chuck portion 15 formed on the plate cylinder of the printing roller 14.

This completes the removal of the printing roll 14 of the large elastic plate 1 from the plate cylinder.

As a result, the large elastic plate 1 is suspended by the support device, and the support device holding hole 4 of the large elastic plate 1 is removed from the holding portion 107 supported by the two rotating arms 106. And replace it with another large elastic plate 1.

The large elastic stencil winding / unloading support device according to the second embodiment of the present invention has the following configuration, and thus has the following effects.

(1) When removing the printing roll 14 from the plate cylinder, the large elastic plate 1 can be held by the large elastic plate winding and removing support device. Since there is no need to lift people, it is very efficient because it does not require labor. (2) Even if the large elastic plate 1 and the plate holders 2 and 3 are heavy, the large elastic plate 1 can be held by the large elastic plate winding / unloading support device. No load is applied.

(a) Therefore, the large elastic plate 1 does not fall onto the printing roll 14 and there is no danger of damaging the large elastic plate 1 or the film forming apparatus.

(b) In addition, since the first plate holder 2 is mechanically lowered by the large elastic plate winding and removing support device, it is difficult for the large elastic plate 1 to shake, and the first plate holder 1 is always kept horizontal. When the large elastic plate 1 is wound around the plate cylinder of the printing roll 14, the tension applied to the large elastic plate 1 can be maintained at a uniform and constant value over the entire surface. Therefore, the large elastic plate 1 does not wind around the plate cylinder in a wavy state.

(3) The large elastic plate 1 can be held by the large elastic plate winding / unloading support device until the large elastic plate 1 is completely wound around the plate cylinder of the printing rolls 14. There is no need to hold it with human hands, so you do not have to hold the plate holder 1 for a long time with hands that have garbage, oil, or sweat. Therefore, dust, oil, and scattered sweat do not adhere to the large elastic plate 1 and the large elastic plate 1 does not easily become dirty.

(4) Since the rotary arm unit 106 was used to mechanically fold the large elastic plate 1 around the plate cylinder of the printing roll 14, the second plate holder 3 was held accurately by the second chuck unit 15. Can be moved to any position.

Note that by appropriately combining any of the above-described various embodiments, the effects of the respective embodiments can be achieved.

The elastic plate winding / removing support device according to the present invention has the following configuration, and has the following effects.

(1) A person who lifts the elastic plate on the film forming device because the elastic plate can be held by the elastic plate winding and removing support device when the printing unit is wound around the plate cylinder. It is very efficient because it does not require labor.

(2) Even if the elastic plate and the plate holder are heavy, the elastic plate can be held by the elastic plate winding / unloading support device, so that a heavy load is not applied to the operator.

(a) For this reason, the elastic plate does not fall on the printing roll, There is no risk of damaging the film forming apparatus.

(b) Also, since the plate holder is mechanically lowered by the elastic plate winding / unloading support device, it is difficult for the elastic plate to sway, and the plate holder can be kept horizontal at all times. When the elastic plate is wound on the plate, the tension applied to the elastic plate can be maintained at a uniform and constant value over the entire surface. Therefore, the elastic plate does not wind around the plate cylinder in a wavy state.

(3) It is not necessary to hold one plate holder by hand until the elastic plate is completely wound around the printing roll plate cylinder. I don't need to grab it. Therefore, garbage, oil, and splattering sweat do not adhere to the aqueous version and the elastic version does not easily become dirty.

(4) Since the rotation plate is used for mechanization, the second plate holder can be moved to an accurate position on the second chuck when the elastic plate is wound around the plate cylinder of the printing roll.

Although the present invention has been fully described in connection with preferred embodiments thereof with reference to the accompanying drawings, various changes and modifications will be apparent to those skilled in the art. It is to be understood that such changes and modifications are intended to be included therein without departing from the scope of the invention as set forth in the appended claims.
