Metal endless belt loading and unloading mechanism and loading and unloading method

The invention relates to a loading and unloading mechanism and a loading and unloading method for a metal endless belt of a belt type machine.

A belt machine is a machine that processes and manufactures various products using a metal endless belt. The advantages of the belt type machine include that the various treatments of the workpiece under various conditions such as high pressure and high temperature can be continuously performed on the same endless belt, and can be processed on the plane at all times until it leaves the endless belt at all. Will apply tension to the processed product, and so on. The type of the belt type machine is various, for example, a film forming machine that directly injects a molten resin onto an endless belt to form a film, or a coating machine that applies a film to the surface of a sheet-like product conveyed on the same endless belt. . These belt machines include a single-belt belt using a single metal, a single-belt machine for performing the required processing on the endless belt, and a double processing of the processed product between the upper and lower metal endless belts. Belt machine.

The thickness of the metal endless belt is 0.6 to 3 mm, and if the length exceeds 8 m, the weight is large, and it is difficult to operate easily. Further, the surface roughness and the processing accuracy of the endless belt required for the product to be processed are also various, and it is necessary to appropriately mount the driving roller or the like according to the use thereof. In particular, in the case of optical products, IT products, etc., where the thickness precision is extremely strict, the seam portion of the endless belt is of course, and the entire surface of the endless belt must be mirror-finished, and not only that, but also special attention is required. The installation does not allow for a slight bump on the surface of the endless belt.

In general, as one of the methods of attaching such a metal endless belt to a belt drive roller or the like, there is a method of attaching a metal belt cover to a drive roller or the like at a setting place of the belt type machine, so that The ends of the metal tape are butted against each other and joined by welding to form an endless belt, which is attached to the drive roller.

In this regard, a method and mechanism for attaching and detaching an elongated metal endless belt are disclosed in Japanese Laid-Open Patent Publication No. 2004-324667 (Patent Document 1). According to this Patent Document 1, when a new endless belt is attached to a rotating roller in a main space surrounded by the first frame, the endless belt is fed into a second frame provided at a position adjacent to the main space. In the auxiliary space, the vertical frame piece attached to the interference portion of the first frame body is removed to form a tape insertion gap, and the endless belt is inserted through the gap, and the endless belt is attached to the rotating roller in the main space. Further, when the metal endless belt attached to the main space is detached from the rotating roller and carried out from the belt type machine, the vertical frame body attached to the interference portion of the first frame body is removed as described above. a sheet forming a belt insertion gap through which the endless belt is pulled out, carried out to the outside of the machine through the auxiliary space, and then the new metal endless belt to be replaced is fed into the auxiliary space, and the rotation roller is mounted to the main space in the above-described order. On the child. After these operations are completed, the frame sheets are reinstalled into the gap. Therefore, it is not necessary to disassemble and assemble the frame of the belt machine in particular, and it is not necessary to adjust the peripheral equipment.

On the other hand, a method of replacing a ring-shaped conveying member of an unspecified material and a replacing device thereof are disclosed in Japanese Laid-Open Patent Publication No. Hei 7-10237 (Patent Document 2). In this method, when both ends of the rotating shaft are supported by bearings, when the annular conveying member stretched on the pair of front and rear rotating bodies fixedly disposed at the center of the rotating shaft is replaced, one end of the rotating shaft and the supporting end are supported. Between the bearings of the portion, there is provided a support member that can support the rotating body by a cantilever type by a rotating shaft, and the bearing on the other side without the supporting member is removed, and the tension of the toroidal conveying member that is stretched is relaxed Next to the endless transfer member, a new endless transfer member is installed. After the installation is completed, the removed bearing is again mounted to the original location. The method is particularly suitable for the replacement of a shorter annular conveying member and a light weight annular conveying member, and the applicable member is a relatively small device having no frame in the middle portion of the two rollers.

Patent Document 2; Japanese Patent Laid-Open No. Hei 7-10237

In the method of attaching and detaching a metal endless belt disclosed in Patent Document 1, since it is necessary to secure a space above the width of the replaced endless belt for replacing the endless belt between the vertical frame sheet and the first and second support blocks, In order to avoid interference between the first and second support blocks and the endless belt, it is necessary to arrange it at the outer end position of the main space.

Further, regarding the above-described rotating roller for driving the endless belt, in order to insert the endless belt, the vertical frame piece needs to be detached from the vertical frame in any case. The vertical frame piece is detachably disposed at a tape insertion position of the vertical frame body, and the vertical frame body is disposed between the main space and the auxiliary space. On the other hand, a bearing for supporting the above-described turning roller is fixedly disposed to the vertical frame body, and once the vertical frame body piece is removed, the turning roller becomes a cantilever support. The maximum load applied to the rotating roller in the cantilever state is increased by a part of the weight of the endless belt, becoming extremely large.

In general, if the width of the endless belt is widened, the amount of the cantilever is also increased. Regardless of the outer diameter of the rotating roller, when the width is narrow, the bending is small, and the load that can be withheld is large, so that the design and work can be easily performed. When the endless belt is widened, a complicated structure and an excessive wall thickness of the component are required, the design is extremely difficult, and the deformation and damage of the peripheral component are easily caused, and the replacement work of the endless belt is also very difficult and dangerous, and therefore, it is necessary to make The cantilever has a strength that is sufficient to withstand.

In addition, the vertical frame disposed outside the main space is also the same, and it is necessary to ensure sufficient strength to support the rotating roller in the cantilever state, and as the maximum load increases, the frame also becomes large, and not only the width of the endless belt but also There are also restrictions on the design of weight and space, and it is the main reason for the increase in cost. Further, the method of replacing the endless belt by the auxiliary space formed by the second frame having the horizontally extending frame and the vertical frame is used, and in the case where the endless belt is long, the number of the mounts is increased, and it is necessary to load and unload them. More time and effort.

On the other hand, even if the ring-shaped transport member disclosed in Patent Document 2 is replaced, it is necessary to separately support the front and rear two rollers when replacing the endless belt, and if it is a short and small-weight annular belt, there is substantially no danger. Since there are no pillars between the two rollers, only the roller portion can be considered. However, if the ring belt is long, the pillars are used between the two rollers, and the construction of the pillar portion also needs to be considered.

The present invention provides a metal endless belt loading and unloading mechanism which is applied to a belt type machine having: a metal endless belt, at least two rollers for rotating the endless belt, and a bearing through a bearing A pair of front and rear roller supports at both ends of the rotating shaft of the roller, the endless belt loading and unloading mechanism having at least two sets of mounting brackets having horizontally extending frames and auxiliary struts.

The horizontally extending frame of the mounting bracket has a dimension in the width direction of the endless belt above the width of the endless belt. One end of the horizontally extending frame body is engageable with a part of the roller support body on the endless belt side in a state in which the extending direction of the horizontally extending frame body is parallel to the width direction of the endless belt. The other end of the horizontally extending frame can be connected and separated from the auxiliary pillar.

In addition, the present invention also provides an endless belt loading and unloading method in which a metal endless belt is inserted in advance into each horizontal extending frame of at least two sets of mounting brackets to which a horizontally extending frame body and an auxiliary pillar are connected. After the body is attached, one end of the horizontally extending frame body is engaged with the roller support body, and the support body block is removed to form an insertion gap of the endless belt, and the endless belt is taken from the roller support body. The insertion gap is inserted, the sleeve is hung on the roller and mounted on the belt machine, the support body block is reinstalled, and one end of the horizontally extending frame body is removed from the roller support body and separated The mount.
