Description

  The present invention relates to a cylindrical honeycomb element substrate used as a support substrate for a catalyst or an adsorbent and a method for forming the same.

  A conventionally known method for manufacturing the cylindrical honeycomb 101 using paper as a base material will be described below with reference to FIGS. 4, 5, and 6. This type of cylindrical honeycomb 101 uses a paper or non-woven fabric containing ceramic fibers, glass fibers, or a mixture thereof as a base paper, and one of the two base paper pairs is a flat sheet that remains flat. 102, the other is formed into a corrugated sheet 103 having a corrugated shape, and these are joined at the ridge line portion of the corrugated sheet 103 to form a single-stage sheet 104, and then the single-stage sheet 104 is laminated in a cylindrical shape to form a honeycomb structure Although the method to do is known, when laminating | stacking the said single stage sheet | seat 104, it is necessary to laminate | stack without crevice and without crushing a waveform shape.

  When there is a gap between the stacks of the single-stage sheets 104, the number of winding stages when winding to a predetermined product size is reduced, so that the number of honeycomb cells is also reduced. When it is carried, the carrying amount decreases and the product performance deteriorates. Further, since the gap between the laminated single-stage sheets 104 becomes a gap, the bonding force between the laminated single-stage sheets 104 is partially extremely weakened, and the rigidity of the cylindrical honeycomb 101 at the time of completion is lowered.

  Also, when the tension of the single-stage sheet 104 is excessive and the corrugated shape is crushed, the number of winding cells increases when the sheet is wound up to a predetermined product size, and the number of cells of the honeycomb also increases. The supported amount of the catalyst or adsorbent increases excessively, or the pressure loss increases when the fluid to be treated is passed through the cylindrical honeycomb cell, resulting in a decrease in product performance.

  In order to prevent laminating gaps between the single-stage sheets, the single-stage sheets 104, which are generally formed by a corrugator, are wound up into a large number of cylinders in a form that temporarily stocks rather than the final product dimensions, The single-stage sheet 104 wound up in large quantities is mounted on the shaft of the feeding device 105 and is wound up again to the product dimensions. Here, in order to wind up the single-stage sheet 104 without a gap, a brake 106 having a torque adjustment function is applied to the shaft of the feeding device 105, or tension is applied to the single-stage sheet 104 immediately before winding up to the final product dimensions. A method is known in which an appropriate tension is applied to the single-stage sheet 104 to be wound by attaching the device 107, and the single-stage sheet 104 is laminated in a cylindrical shape without a gap.

  In addition, in the method of forming a cylindrical metal catalyst alone, it is known that the method of referring to Japanese Patent Application Laid-Open No. 9-38504 prevents collapse of the honeycomb shape at the center and ensures sufficient strength. Yes.

  Hereinafter, a method for forming the single-stage sheet laminated in the cylindrical shape will be described with reference to FIG.

As shown in FIG. 6, in a state where the flat plate material 108 and the corrugated material 109 are alternately stacked, the core portion 110 is manufactured by winding up the plate material 108 and the corrugated material 109 while applying a predetermined tension to the plate material 108 by the tension applying device 107. In the metal catalyst carrier manufacturing method, the core core 110, which is the center of the core, is reduced by reducing the tension applied to the flat plate material 108 in accordance with an increase in the number of turns of the manufacturing core 110 that is rolled up in a circular shape and expanded. The tension acting on the core core portion 110 can be prevented from being crushed.
Japanese Patent Laid-Open No. 9-38504

  In such a conventional method for laminating a cylindrical honeycomb using paper as a base material, the tension applied to the fed single-stage sheet varies depending on the diameter of the single-stage sheet that is attached to the delivery apparatus and delivered, and the diameter of the single-stage sheet is as described above. When is large, the tension is small, and when the diameter is small, the tension is large. As a result, the honeycomb shape of the wound single-stage sheet has a tendency that the height of the honeycomb shape is crushed and lowered at the central portion and is increased at the outer peripheral portion.

  Further, in the method of forming a cylindrical metal catalyst alone, the tension of the corrugated material at the time of winding is adjusted to be constant, but the base material can be manufactured only with a metal or other highly rigid material. In the case of paper having low rigidity such as paper, the corrugated material is crushed or deformed, so that appropriate tension cannot be applied.

(Embodiment 1)
FIG. 1 shows a view of a cylindrical honeycomb winding and laminating apparatus. Paper or non-woven fabric containing ceramic fiber, glass fiber, or a mixture thereof is used as a base paper, and one of the two base paper pairs is formed into a flat sheet 102 while the other is formed into a waveform. The corrugated sheet 103 is joined, and the single-stage sheet 104 joined by the ridge line part of the corrugated sheet 103 is corrected to meander by the winding introduction part 1 and guided to the winding shaft 2, and one end of the single-stage sheet 104 is connected to the corrugated sheet 103. And fixed to the take-up shaft 2.

  The fixing method may be any method as long as the single-stage sheet 104 in the winding process does not slide out of the winding shaft 2. In the embodiment of the present invention, the outer peripheral surface of the take-up shaft 2 is divided into three parts, and is structured to be movable about 2 millimeters radially about the center of the take-up shaft 2. The outer diameter of the sheet is expanded and contracted by about 4 mm so that the single-stage sheet 104 does not slide from the winding shaft 2.

  First, prepare a flat sheet separately, with a length that is equal to or greater than the circumferential dimension of the winding shaft and the width of the single-stage sheet 104 that winds the width, and wind the winding shaft 2 with the outer diameter dimension reduced. The honeycomb center shaft 3 is formed by fixing the ends so as not to be peeled off with an adhesive or an adhesive tape, and the outer diameter of the winding shaft 2 is expanded so that the honeycomb central shaft 3 and the winding shaft 2 do not slide. Like that. Here, the outer diameter of the take-up shaft is set to be the inner diameter of the target cylindrical honeycomb 101 when the expansion / contraction mechanism is expanded.

  One end of the single-stage sheet 104 is fixed to the honeycomb central shaft 3 with an adhesive tape or an adhesive, and the winding end 4 that is the outermost end of the single-stage sheet 104 in the lamination process is pressed against the cylindrical honeycomb. The winding shaft 2 is wound around the winding shaft 2 by the rotational movement of the motor 6 attached to one end of the winding shaft 2. Here, the position of the winding shaft 2 is linearly moved so that the winding gap, which is the distance between the outermost arc of the cylindrical honeycomb in the stacking process and the pressing roller 5, is always constant regardless of the number of stacking stages.

  Any method may be used for moving the take-up shaft, but in the embodiment of the present invention, there is a slide plate 7 to which the take-up shaft 2 is attached, and a linear movement is provided between the slide plate 7 and the main frame 8. A guide rail 9 and a ball screw 10 are attached to each other, and a moving motor 11 is attached to one end of the ball screw 10. The ball screw 10 is rotated by driving the moving motor 11, the slide plate 7 is linearly moved on the main frame 8, and the winding shaft 2 attached to the slide plate 7 is linearly moved. Yes.

  The position of the winding shaft 2 is determined and controlled with a correlation with the number of stacked layers. The position of the take-up shaft is equal to the sum of the heights existing between the take-up shaft 2 and the pressing roller 5 at any time when the single-stage sheets 104 are laminated, or one sheet of the single-stage sheets 104 from the sum. It is appropriate to maintain a value obtained by subtracting an interference dimension of about 10 percent of the molding height and at most 20 percent. Specifically, the sum of the thickness of the flat sheet of the central shaft 3 and the product of the height of the single-stage sheet 104 and the number of winding stages is about 10% of the molding height of one single-stage sheet 104, and at most 20%. By controlling to the value obtained by subtracting the following dimensions, it is possible to form the cylindrical honeycomb 101 by stacking the single-stage sheets 104 so that there is no gap between the single-stage sheets 104 and the cells are not crushed.

  The method of moving the take-up shaft 2 here is an example of motor drive, but the purpose can be achieved if it is synchronized with the rotational motion of the take-up shaft 2.

  Therefore, instead of motor driving, a cam is attached to the take-up shaft, the rotational motion is converted into a linear motion, and the amount of this linear motion is determined at any time when the cylindrical honeycomb 101 is laminated. Equal to the sum of the heights of the ones existing between the presser roller 5 or the sum of the heights minus about 10 percent of the molding height of one single-stage sheet 104 and a maximum of 20 percent or less. It can be replaced by setting.

  Further, instead of the motor drive, the rotational motion from the pinion attached to the take-up shaft is transmitted to the rack through the speed reducer and converted into linear motion, and the amount of this linear motion is stacked on the cylindrical honeycomb 101 described above. At any point in time, the sum of the heights existing between the take-up shaft 2 and the pressing roller 5, or from the sum, about 10 percent of the molding height of one single-stage sheet 104, and at most 20 percent. It can be replaced by setting to the value obtained by subtracting the following dimensions.

  In the drive of the winding shaft 2 described above, the interval between the winding shaft 2 and the pressing roller 5 exists between the winding shaft 2 and the pressing roller 5 at any time when the cylindrical honeycomb 101 is laminated. It is appropriate to maintain a value that is equal to the total sum of the heights of the objects to be processed, or that is obtained by subtracting a maximum of 20 percent or less from the total sum, which is about 10 percent of the molding height of one single-stage sheet 104. The linear movement timing of the winding shaft 2 is one linear movement per rotation of the winding shaft 2. When the number of stacking steps of the cylindrical honeycomb 101 is relatively small, the step that is the forming height of the first single-stage sheet 104 that is the start of winding appears remarkably on the outermost periphery, so the linear movement timing of the winding shaft 2 is also 1 However, when the number of stacking steps of the cylindrical honeycomb becomes relatively large, the step which is the forming height of the single-stage sheet 104 at the first stage of winding becomes inconspicuous, and the outer shape of the stacked honeycomb becomes circular. In some cases, the linear movement timing of the take-up shaft 2 may not match the actual timing once per rotation.

  In order to solve this, the height of what exists between the winding shaft 2 and the pressing roller 5 is theoretically calculated, and the straight line that the winding shaft 2 should move per rotation is calculated based on the calculated value. The dimension is calculated, the winding clearance is determined with the calculated value, the timing of linear movement of the winding shaft 2 is subdivided so as to satisfy it, and the winding shaft 2 is rotated several times per rotation, or There is a method of moving continuously. Further, the calculated value is set to about 10% of the molding height of one single-stage sheet 104, and a tightening margin obtained by subtracting a dimension of 20% or less at maximum can be wound and laminated without any gap. .

  Further, as a method of laminating the single-stage sheets 104 without any gaps, the outer diameter of the cylindrical honeycomb 101 in the winding and laminating process is measured with a contact or non-contact sensor, and the measured value and the winding in any laminating process are measured. By comparing the theoretical calculation value that is the position of the take-up shaft 2 and making corrections so as to match the measured dimensions, slippage occurs between the take-up shaft 2 and the single-stage sheet 4 and the number of take-up steps is affected. Can be avoided.

  Here, the driving for securing the winding gap described above has been described by moving the winding shaft 2, but the same effect can be obtained by moving the pressing roller 5. . Moreover, the press roller 5 only needs to be able to fulfill the role of pressing, and even if it is not a roller, a plate-like one may be used as long as the surface is smooth.

  FIG. 2 shows a configuration for preventing the looseness of the single-stage sheet 104. Immediately after the single-stage sheet 104 passes through the winding gap and is laminated on the cylindrical honeycomb 101, the belt 12 is pressed against the outer peripheral curved surface of the cylindrical honeycomb 101 in the lamination process, so that the cylindrical honeycomb 101 The frictional force between the outermost surface and the belt 12 can prevent sagging of the single-stage sheet 104 and prevent a gap from being generated between the single-stage sheets 104.

  Further, as a method for adjusting the frictional force, one end closer to the cylindrical honeycomb 101 is fixed, a weight 13 is hung on the other end, and the load of the weight 13 is changed. .

The sheet was formed into a corrugated sheet with a dedicated corrugator at 2.65 mm and a height of 1.5 mm to form a single-stage sheet 104. The single-stage sheet 104 is passed through the winding introduction part 1 of the winder, and the meandering in the direction perpendicular to the flow direction of the single-stage sheet is restricted to wind up, thereby aligning the end face at the end of the winding lamination.

  First, a base paper of the same type as that of a single-stage sheet was cut into a honeycomb central shaft 3 having a width of 155 mm and a length of 120 mm, wound around the winding shaft 2, and the end portion was fixed with an adhesive tape. The material dimensions of the honeycomb central shaft 3 are the same as the width of the single-stage sheet and the length is the inner diameter dimension of the cylindrical honeycomb when completed, and is about 1.3 times the circumference of the winding shaft 2. did.

  Next, the single-stage sheet 104 was fixed to the honeycomb central shaft 3 with an adhesive tape, and the distance between the winding shaft 2 and the pressing roller 5 was set to 1.5 mm. The above-mentioned 1.5 mm is from 1.66 mm which is the sum of the paper thickness of the winding center shaft 3 of 0.16 mm and the molding height of the single-stage sheet 104 of 1.56 mm to the molding height of the single-stage sheet 104. It was obtained by subtracting 10 percent 0.15 millimeters and rounding off to three decimal places. The position of the winding shaft 2 at this time is the origin, and when the winding shaft 2 makes one rotation, the winding shaft 2 is on the side opposite to the pressing roller 5 and the molding height of the single-stage sheet 104 is 1.5 mm. Moved straight. The linear movement was divided so that the winding shaft 2 performs four linear movements per rotation, and the linear movement amount per one time was set to 0.375 mm.

  The linear movement method of the winding shaft 2 includes a slide plate 7 to which the winding shaft 2 is attached, and a guide rail 9 and a ball screw 10 for linear movement are attached between the slide plate 7 and the main frame 8. The motor 6 is attached to one end of the ball screw 10. The ball screw 10 is rotated by driving the motor 6, the slide plate 7 is linearly moved on the main frame 8, and the take-up shaft 2 attached to the slide plate 7 is linearly moved.

  The single-stage sheet 104 was laminated to a predetermined size, and the end portion was fixed with an adhesive tape to form a cylindrical honeycomb 101.

  The cylindrical honeycomb manufactured using the method of the present invention has the effect of stabilizing the cell shape, dimensions and dimensions of the honeycomb at the center and outer periphery of the cylinder, and the catalyst or adsorbent is added to the cylindrical honeycomb. The supported filter can exhibit a stable purification or adsorption action.
