[Conventional technology]

A strip-shaped material impregnated with a fixative is continuously bent into a wave shape, and the wave-folded material is rolled up so that both ends thereof are joined. Then, this rolled material is molded into a predetermined shape, and the final shape is held and fixed by fixing the material with a fixing agent impregnated into the material. In the manufacturing process of such filter elements, there is a need for a rounding device that can automatically and quickly round the corrugated material.

[Purpose of the invention]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rounding device that can automatically and quickly roll a band-shaped corrugated material in response to the requirements of conventional rounding devices.

[Structure of the invention]

In order to achieve the above problems, the present invention has the following configuration. That is, a holding block divided into a plurality of pieces holding the filter element material bent into a wave shape is arranged on the back plate. Two adjacent holding blocks among the plurality of holding blocks are connected to be rotatable on the plane of the back plate. Further, any two holding blocks among the plurality of holding blocks are each rotatable, and at the same time,
It is also rotatably fixed to the back plate.
The holding blocks located at both ends of the holding blocks are connected to rounding moving means for moving the holding blocks located at both ends so that they are connected to each other. The position of this rounded holding block is secured by fixing the holding blocks located at both ends thereof using connecting means.

The strip material 110 with lines carved on its surface further enters the shaping roller 112, and the shaping roller 1
12, it is bent and shaped into a continuous wave shape. Then, it is further cut into a predetermined length by the cutting device 114, and the feed chain 116
conveyed in its longitudinal direction by

The element 113 cut into a size corresponding to the length of one filter element is conveyed from the folding device 100 onto the guide plate 209 of the shrinking device 200 manually or by a moving device (not shown). The element 113 conveyed into the contraction device 200 is moved by the upper guide arrow 220 of the expansion and contraction device 201.
, the part where the wave height is the smallest is supported from above, and the lower guide arrow 227 supports from below at the position where the wave height is the highest. When the drive source 253 is driven, the chain 213 is driven in the direction of arrow A in FIG. 1 via the joint 251 and sprocket 211. Block 207 also moves in the direction of arrow A in the figure via attachment 241 that engages with chain 213. That is, block 207
If moves, move the upper guide bar 20 to this block.
The upper block 202 and the lower block 203a, which are connected to each other by the lower guide bar 205a and the lower guide bar 205b, also move in the direction of arrow A in the figure. At this time, the upper block 202 is connected by a pantograph 223, and the lower block 202 is connected to each other by a pantograph 223.
03, the lower guide arrow 227 connected thereto moves along the guide groove 235, thereby narrowing the interval toward the center of each. As a result, the element 113 slides on the guide plate 209 in the direction of arrow A in the figure, and at the same time is contracted in the wave pitch direction along the upper and lower guide arrows.

The element 113 that has been reduced to a predetermined size reaches the shaping gate 290, and at that position is pushed out by the extrusion device 390 toward the rounding device 300 side.

That is, element 113 is rounding device 300
The elements are pushed into element insertion spaces 350 formed in each of the blocks 331 to 341.

Then, by driving the actuator 375, the rack 373, the first gear, the second gear 3
71, 372, levers 369, 370, and link plates 365, 366, the linear state is rolled into a cylindrical shape around the fixing pin 391 as shown in FIG. As shown in FIG. 5, each rounded block 331, 341 is a link 361.
By inserting the pins into the pin insertion holes 362 of a and 361f, the rounded shape is maintained. In this way, when the rounding of the shaping block is completed, the actuator 409 is driven to remove the back plate 20.

When the shaping block 600 has completed its movement, the actuator 401 is driven to push out the pushing rod 405.
is pushed out and driven in the direction of arrow S in the figure. The extrusion rod 405 passes through the extrusion rod insertion hole 381 formed in the back plate 301 and is inserted into the rounding device 30.
Push out the filter elements held within each block of 0. The element pushed out by this pushing rod 405 is transferred to the shaping block 60.
0 into the shaping space 605. When one filter element is housed in the shaping block 600, the shaping block 600 is returned to the position shown by the solid line in FIG. 9, and then the back plate 301 is returned to the position shown by the solid line in FIG.

By repeating the above-described operations, the filter element is again loaded into the rounding block, and the second filter element is pushed into the shaping block 600 from the upper opening end. As a result, the first filter element is pushed out toward the lower opening end by the next inserted filter element, and by repeating this operation, the filter elements are pushed one after another from the upper opening toward the lower opening end. being pushed out. At this time,
The filter element inserted from the upper opening end is gradually shaped into the final shape as it passes through the shaping space 605, since the shaping space 605 is gradually changing to the final shape. Ru.

Filter element 11 shaped into the final shape
3 is loaded into the pallet space 510 of the pallet 501 located in the pallet space 611, and by driving the pallet unloading actuator 455 rightward in FIG. 9, the pallet 501 is conveyed rightward in the figure. be done.

Note that when transferring elements from the shaping block 600 to the palette 501,
01 is lifted up most upwardly (in the direction of arrow U) by the actuator 449, and the pallet 50
After loading of the element 113 into the element 113 is completed, the actuator 449 is driven in the direction of arrow U' and returns to its original position. Then, in this restored state, the actuator 4 is activated as described above.
55 is activated, and the pallet 501 is discharged.

The discharged pallet 501 is transferred to the element 11
3 is transported to the next step, an element curing device (not shown), with the material loaded.

Note that when the element 113 is transferred from the shrinking device 200 to the rounding device 300, the rounding device 3
00 blocks 331 to 341 are arranged on a straight line. Also, when loading the shaping block 600 from the rounding device 300, the block 331
341 has a rounded shape as shown in FIG. Further, in the extrusion device 390, an actuator 391 drives the extrusion rod 395 in the directions of arrows Q and Q' in the figure, and an actuator 425 drives the extrusion rod 395 in the directions of arrows P and P' in the figure. .

Further, the back plate 301 is driven in the directions of the arrows R and W' by the actuator 409.
A rotational drive is performed in the R′ direction. Further, the shaping block 600 is reciprocated by the actuator 453 from the position shown by the chain double-dashed line to the position shown by the solid line in FIG. 9 every time the filter element 113 is discharged onto the pallet 501. The filter element shaped by this operation is shaped into a shape having a plurality of pleats as shown in FIG. 15.

Claims (1)

[Scope of Claims] 1. A rounding device for shaping a continuous wave-folded band-shaped filter element material so that both ends thereof are joined, the rounding device comprising: a plate-shaped back plate having one plane; A holding block that is divided into a plurality of parts while continuously having a holding space for holding the filter element material bent in a wave shape and arranged on one plane of the back plate; holding block connecting means for connecting each of two adjacent holding blocks so as to be rotatable on one plane of the back plate; a holding block fixing means that is rotatably fixed to the back plate; and a holding block that is connected to holding blocks located at both ends of the holding blocks, and held so that the holding blocks located at both ends are in contact with each other. A rounding device for filter element material, comprising: a shaping drive means for moving the block; and a connecting means for connecting holding blocks at both ends that are in contact with each other at that position.
