Dande in which a wire mesh processed for each type of work is wound around the cell
It is necessary to prepare a number of dandy rolls of the same mark due to wear, deformation and breakage of the mark due to use , fine fibers in the stock , and clogging of the filler. Further, when the insertion mark requires a fixed position, it is necessary to provide a mark whose position is changed according to the papermaking shrinkage ratio which changes depending on the stock and the processing conditions. The factories that manufacture many kinds of papermaking papers with the insertion mark in this way have tens of dandy rolls. The work of processing the plow put mark in wire mesh is required a special technology and many days, also in cell

Means for Solving the Problems A cell having rims at both ends and fitted with a wire mesh provided with a clearance mark, and a journal are detachable by being fitted to the rim, and are separated and assembled. Open paper type piercing dandy roll for paper machine, perfect circular shape retention of separated cell and protection of rims at both ends of the cell as well as screw holes for auxiliary equipment in transportation and storage In order to assemble integrally the dandy roll component parts divided into three parts, a shape retaining plate, a cell and both end journals having a fixing hole, while supporting both end journals, it is freely rotatable, and with respect to the base. And a mechanism to rotate the cell with a worm mechanism while supporting it at the four points in order to attach the wire mesh to the wire mesh and to perform the wire mesh insertion mark processing. A configuration of bets the papermaker open journal type plow inserting type dandy roll assembly apparatus wherein. That is, in the present invention, the joint between the cell and the journal portion is of a separated and assembled type so that only the cell can be handled separately. Since the cell is cage-shaped and it is difficult to maintain a cylindrical shape in terms of strength, attach a rim at the end of the cell to ensure roundness, and align the axis of the rim and the journal straight when assembling. Both are spigot-type fittings for connection. However, since the cell must be made lightweight, there is a limit to the strength of the rim that maintains the roundness. The shape-retaining plate is light in weight for easy attachment and detachment. Since it is impossible to manually assemble both the cell and the journal due to its weight, an assembling device is provided to enable easy and safe separation and assembly. In addition, this assembling apparatus is also used as a work table for setting a wire mesh on a dandy roll cell or performing a penetration mark processing on the wire mesh, so that this work table can perform all operations for forming a use condition of a dandy roll. To In order to reduce the storage area and eliminate deformation due to storage, the cells separated from the journal will be in a vertical storage format. In addition, a shape retaining plate having a larger diameter than the rim end surface is attached to the rim end surface of the cell serving as the installation surface, and in addition to preventing damage to the end surface, the area of the rim end surface is increased to increase the installation stability. Further, since the diameter of the shape retaining plate is larger than the end surface of the rim, the wire mesh is protected when the cell falls. Also, make the required holes in the shape retention plate,
By using this hole in combination with various auxiliary mechanisms, it is possible to prevent a fall during storage, a fall during transportation, and a smooth operation of verticalizing the shaft from a horizontal position.

[0007]

[Action] open journal type dandy roll of the present invention, detach the cells and the journal, since only a separate cell, external dimensions only journal portion becomes small, and
Is lighter al, transportation, it is easy to handling and storage
You. Also, it is sufficient to provide only a few journals for several tens of cells, and the production cost per dandy roll is significantly reduced. Easily it is possible assembly of the cell and the journal, also work and that Ru sticking cells, workability now work to plow insertion mark processing on gold network can be set enhanced by the assembling apparatus by assembling apparatus I do. Since it is a single cell, it can be stably stored vertically due to its shape, and the storage area can be greatly reduced.
In addition, the rotating operation required for preventing the occurrence of bending due to the conventional horizontal placement becomes unnecessary. And the use of the shape-retaining plate allows the separated cells to be kept in a circular shape, so the cell structure
Dandy roll light weight
Conditions are maintained. Further attaching the shape retention plate to the cell
Accordingly, the protection and the gold net surface during cell falls, enables vertical hanging transportation required for upright storage of upright storage can prevent damage to the rim <br/> end surface of the cell. Also, in combination with a fixing bracket with protrusions to prevent falling during transportation by a transport vehicle
Thus, the gold net unit cell Ki de be safely supported by the outer position, it's still <br/> in combination with shape retaining plate and the vertical hanging guide bracket, from a horizontal position on the transportation vehicle A body that can be suspended smoothly vertically
Can be transferred to shape. In addition, it is easy to use in combination with a swing type double claw hook, and the fall prevention can be secured safely .

[0011]

The open- dwell type dandy roll according to the present invention has the following features. [1] Since the cell and the journal are separated and only the cell is separated, the outer dimensions are reduced by the journal . Further, the weight is reduced and the handling becomes easy. [2] It is sufficient to provide only a few journals for several tens of cells, and the production cost per dandy roll is significantly reduced. [3] Easy with assembly equipment
The cell and the journal can be assembled, and the assembling apparatus allows a series of operations for attaching a wire mesh and making a cut mark on the wire mesh, thereby improving workability. [4] Since only cells are used, vertical storage can be stably performed from the shape thereof, and the storage area can be significantly reduced. In addition, the rotating operation required for preventing the occurrence of bending due to the conventional horizontal placement becomes unnecessary. [5] shape-retaining plate
