Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a detachment method and a detachment mechanism for attaching and / or detaching a metal endless belt formed in advance in an endless manner to a plurality of belt rotation rolls arranged in a space surrounded by a frame.
[0002]
[Prior art]
In recent years, various products have been processed and manufactured using metal endless belts. These processing and manufacturing machines are often simply referred to as belt machines. The advantages of this belt machine are that various processes can be performed continuously on the same belt under various conditions on the workpiece, processing can always be performed on a flat surface, Tension may not be applied until the belt is released. There are various types of belt machines, for example, a film forming machine that directly manufactures a film while pouring a molten resin onto a belt, or a coating machine that coats a thin film on the surface of a sheet product conveyed on the belt. is there. For these belt machines, a single metal endless belt is used, and a single belt machine that performs desired processing on the workpiece on the belt and a workpiece between the upper and lower metal endless belts. There are double belt machines that perform various types of processing.
[0003]
As a single belt machine, for example, there is a film casting device for optical use, and a metal endless belt having a mirror-finished surface that travels in one direction from a specially designed T-die through a liquid resin supplied from a high-precision gear pump. It is supplied to the upper side, and is taken out in a film or sheet shape while being desolved or polymerized with the rotation of the belt. At this time, the width and thickness of the film or sheet are controlled with high precision, and the product film is manufactured without any tension in all directions, so that a high-quality film without optical distortion can be manufactured. It is.
[0004]
As an example of the single belt machine, there is a single belt machine disclosed in Patent Document 1, for example. This single belt machine is a drop forming machine for forming a fluid chemical product into particles. This drop forming machine generates a fluid pressure by rotating a rotating screen having an internal chamber for accommodating a flowable chemical product under atmospheric pressure and causing the flowable chemical product to collide with a pressure member in the room. The fluid chemical is extruded through an opening in the screen to form a drip, which is dropped onto the conveying surface of a metal endless belt traveling on one side. The drip dropped on the transport surface is transported and solidifies into particles, from which it is removed and collected. The particles are, for example, particles made of chemical products such as drugs, seasonings, fragrances, synthetic detergents, and resin stabilizers.
[0005]
On the other hand, a double belt machine continuously performs various processes such as heating / cooling, reaction, pressurization / lamination, and mirror-surface transfer while conveying a workpiece between upper and lower belts. Heat treatment equipment for boards, rubber, composite sheets or boards, resin coating equipment for printed circuit board surfaces, equipment for mass production of bonded products with metal and rubber, laminating equipment for flexible substrates specially treated at high temperatures, etc. Can be mentioned. For example, according to Patent Literature 2, a work W in which an inlet sheet having an IC chip mounted on a coil antenna is arranged between card base materials is made of a metal endless, which is arranged vertically and runs in one direction in a facing belt region. There is disclosed a double belt machine which manufactures a resin card with a built-in IC chip by holding it between belts, heating it with a heating / pressing device, and then applying pressure and cooling.
[0006]
Further, as another example of this double belt machine, for example, in Patent Document 3, two or more sets of a pair of metal endless belts traveling in the same direction and at the same speed are installed in series, and the unfoamed resin sheet is formed as described above. A method for continuously producing a foamed sheet having uniform air bubbles while nipping and transporting with a pair of belts is disclosed. In this method, at least both sides of the foamed sheet conveyed while being pressed by the endless belts of the first set and the second set are controlled to a temperature equal to or lower than the melting point of the resin used. The second set of endless belts is advanced at a speed 5 to 1000% higher than that of the first set, and the third and subsequent endless belts are advanced at substantially the same speed as the immediately preceding endless belt. In the endless belts of the first set and the second set, the temperature of the sheet pressing belt on the inlet side and the temperature of the sheet pressing belt on the outlet side are controlled respectively, and the endless belts of the third and subsequent sets are controlled. Is controlled to a predetermined temperature.

[Problems to be solved by the invention]
By the way, as described above, all of Patent Documents 1 to 3 use a metal endless belt, but there is no description on how to mount the metal endless belt on a machine. This type of metal endless belt has a large thickness (0.6 to 3 mm) and a length of more than 8 m in many cases, and is heavy and difficult to handle easily. In addition, the surface roughness and the processing accuracy of the belt required by the product to be processed are various, and the method of mounting on a drive roll or the like must be changed depending on the application. For example, when extremely strict accuracy is required for thickness accuracy such as optical products and IT products, it is necessary to mirror-process the entire surface of the belt, not to mention the seam of the belt. There must be no irregularities on the surface of the belt.
[0009]
Normally, to attach this kind of metal endless belt to a belt drive roll, etc., (1) hang the metal belt around the drive roll at the installation site of the belt machine, butt the ends of the belt and weld by welding. A method of manufacturing an endless belt by connecting it and mounting it on a drive roll. (2) A metal endless belt is manufactured in advance at a location away from the installation site of the belt machine, and this is installed at the installation site of the belt machine. And a belt-mounting method in which the belt is mounted on a driving roll or the like. After the mounting of the belt is completed, a predetermined tension is applied to the belt by a tension roll or the like. This tension is also up to 7-10kg / mm ² It is necessary to secure sufficient tensile strength against these strong pulls, especially at the seam portion of the endless belt.
[0010]
Although the belt mounting method described in (1) above is common, when the belt ends are connected at the belt mounting site by welding or the like, even if welding is possible, additional processing accompanying welding is required. Attempting to do so is difficult in a narrow work space, and often the required processing accuracy cannot be obtained. In particular, even if the wall thickness is to be made uniform between the welded portion and other parts, when welding is performed on site, the welded part is slightly dented than the other parts, and the product is processed with high precision. If this is required, the belt cannot be used. Therefore, especially in the case of a belt machine that requires high-precision processing of a product, the belt mounting method described in (2) above is adopted.
[0011]
By the way, as described above, the metal endless belt mounted on this type of belt machine is not only heavy but also extremely long. In addition, even when the belt is driven, the belt must not fluctuate not only in the width direction but also in the thickness direction under severe processing conditions such as high-temperature heating, cooling, and pressing. As a result, in most belt machines, in addition to the heating device, the cooling device, the pressing device, and the like, a tension applying device and the like are installed inside and outside the endless belt. Further, a large number of support frame frames are arranged around the belt for fixing and supporting these devices, and the frame frame surrounds most of the endless belt.
[0012]
Therefore, as described above, an endless belt is manufactured in advance at a place other than the site, and when the belt is to be carried into the site and replaced when the belt is replaced, the support frame must be disassembled and reassembled. This not only wastes a lot of labor and time, but also makes it necessary to adjust various devices each time the system is restarted, further adding time and maintenance costs, and greatly reducing productivity. Let me.
[0013]
The present invention has been developed in view of such a situation, and its purpose is to provide a belt machine of this type, which does not require special disassembly or assembly of a frame or the like, and furthermore, peripheral devices based on disassembly or assembly. It is an object of the present invention to provide a method and a mechanism for attaching and detaching a metal endless belt which does not require readjustment.
[0014]
Means for Solving the Problems and Functions and Effects
In order to achieve the above object, a basic configuration of a method for attaching and detaching a long metal endless belt according to the present invention includes a main frame surrounded by a first frame having at least one first vertical frame and a horizontal frame. A method of attaching and detaching a long metal endless belt that rotates in a space to a pair of front and rear belt rotation rolls, at a portion orthogonal to the rotation direction of the metal endless belt and adjacent to the main space, In relation to the vertical and horizontal frames, providing an auxiliary space having a volume equivalent to the main space by a second frame frame having a second vertical frame and a horizontal frame, wherein a metal endless belt is provided in the auxiliary space. Loading a part or all of the belt, removing a vertical frame piece attached to the interference portion of the first vertical frame that interferes with the endless belt from the first vertical frame to form a belt insertion gap. Inserting the metal endless belt into the main space through the belt insertion gap, and attaching the metal endless belt to the belt rotation roll; and attaching the metal endless belt to each belt rotation roll, Reattaching the vertical frame piece to the belt insertion gap formed in the vertical frame.
[0015]
In order to carry out this attaching / detaching method efficiently, the attaching / detaching mechanism of the long metal endless belt according to the present invention is characterized in that the metallic endless belt which is wound around at least the belt rotating rolls disposed in the front and rear directions is rotated by the belt. A mechanism for attaching and detaching to and from a rotating roll, wherein the metal endless belt includes one or more first frame frames having a plurality of first vertical frames and horizontal frames arranged so as to surround a belt width direction of a main rotating space of the metal; The pivot main body formed inside a second frame having a second vertical frame and a horizontal frame disposed adjacent to the main pivot space and associated with the first vertical and horizontal frames. An auxiliary space having a volume space equivalent to that of the space, and a part of one or more first vertical frames disposed at a boundary between the pivoting main space and the auxiliary space so as to be attachable to the auxiliary space. belt It is characterized in that it comprises at least a vertical frame piece forms a belt insertion gap for excessive.
[0016]
For example, when a new metal endless belt created at a place other than the site is to be wrapped around the belt rotating roll from which the metal endless belt has been removed, first, the main belt space is set. The metal endless belt is carried into an auxiliary space adjacent to the space. In this loading, the second vertical frame arranged outside the auxiliary space is configured to be removable, and the second vertical frame is removed and removed, and then loaded. In this case, since no particular load is applied to the horizontal frame other than its own weight, there is no inconvenience in terms of safety even if the horizontal frame is temporarily put in a cantilevered state.
[0017]
The new metal endless belt is carried into the auxiliary space, and is once hooked on a horizontal frame constituting the auxiliary space. In this case, it is preferable to wind a soft material such as flannel around the horizontal frame so as not to damage the metal endless belt. Next, after the second vertical frame is newly set at the original position, the vertical frame piece attached to the first vertical frame is removed. When the vertical frame piece is removed, a belt insertion gap is formed in the middle of the first vertical frame, through which the metal endless belt can be inserted horizontally. After inserting a new metal endless belt through the belt insertion gap, the endless belt is mounted around belt rotation rolls disposed in front and behind the main space. At this time, the tension roll and the like are at the standby position, and the belt can be easily mounted on the belt rotation roll because the belt has a sufficient length to be mounted when the belt is mounted. When this mounting is completed, the vertical frame piece detached from the first vertical frame is fitted into the original belt insertion gap, and then fixed by an appropriate fixing means such as a bolt.
[0018]
As is apparent from the above description, the metal endless metal, which is a heavy object manufactured in advance by a simple operation of merely attaching and detaching a vertical frame piece which is a part thereof without dismantling the first frame frame surrounding the main space. The belt can be easily worn. As a result, the operation of adjusting the peripheral devices after mounting can be simplified, and the operating efficiency is greatly improved.
[0019]
Further, after a new metal endless belt is mounted as described above, when the replacement time comes due to long-term operation, the endless belt must be removed from the belt rotation roll. In the method for attaching and detaching the metal endless belt of the present invention, in such replacement, the vertical frame piece attached to the interference portion of the first vertical frame that interferes with the metal endless belt is attached to the first vertical frame. Removing the belt from the frame again to form a belt insertion gap, pulling out the metal endless belt mounted around the belt rotating roll through the belt insertion gap, into the auxiliary space, and then carrying it out of the frame. Also included.
[0020]
In addition, the method of attaching and detaching the metal endless belt of the present invention may also include, at the time of the above-mentioned belt attaching / detaching operation, supporting the roll surface of the belt rotating roll with a support block from below so as not to rotate. If the roll surface of the belt rotation roll is non-rotatably supported from below by the support block, the rolls do not rotate when the belt is attached or detached, and the detachment operation can be performed smoothly.
[0021]
