Abstract
An absorbent product manufacturing apparatus comprises a pulp feed mechanism (2) for feeding a pulp sheet along a lower surface of a pulp guide part (2411) and a pulp crushing mechanism (3) for crushing the pulp sheet from the pulp feed mechanism (2). The pulp crushing mechanism (3) crushes the pulp sheet with a first crushing cylinder (312) and a second crushing cylinder (322) provided, being inclined with respect to a direction of feeding the pulp sheet. This reduces a force of drawing the pulp sheet in the feeding direction and suppresses an increase in movement speed of the pulp sheet in crushing a near-rearend portion of the pulp sheet. As a result, it is possible to increase the amount of crushed pulp to be generated in a unit time and uniformity in quality thereof.

Adsorption production manufacturing equipment 1 comprises along (X) the pulp feed mechanism 2 of direction conveying pulpboard 9 of predetermined pipeline at Fig. 1, the pulping mechanism 3 that the pulpboard of pulp feed mechanism 2 being carried in pulp feed mechanism 2 downstreams 9 is pulverized, adsorption production by the molded formation adsorption production 90 of pulping that pulping mechanism 3 is produced forms mechanism 4, and the control section 5 of controlling these mechanisms.Prepare in the equipment 1 at adsorption production, pulp feed mechanism 2 and pulping mechanism 3 pulverize pulpboard 9 as pulp crushing apparatus and are used for adsorption production.
The pulpboard that is placed with many stratiform pulpboards 9 above pulp feed mechanism 2 comprises is stacked part 21, stack the pulpboard feel trim actuator 22 that part 21 unloads pulpboard 9 one by one from pulpboard, reception from the pulpboard 9 of pulpboard feel trim actuator 22 with its along (X) conveyer 23 carried of direction, and be in conveyer 23 (X) a side directed pulpboard 9 arrives the pipeline 24 of pulping mechanisms 3.
Fig. 2 and Fig. 3 amplify expression pipeline 24 and pulping mechanism 3 and near front view and plane thereof.For the ease of explaining, in Fig. 2, changed the direction of expression part pulping mechanism (second disintegrating mechanism 32), the internal representation (situation of Fig. 5 and Fig. 7 is identical therewith) in Fig. 3 of part pulping mechanism (first disintegrating mechanism 31 and second disintegrating mechanism 32).
As shown in Figure 2, pipeline 24 comprises upper plate 241 and lower plate 242, and each is tabular substantially, respectively (+Z) and (Z) the main surface of side contacts pulpboard 9.Pulp feed mechanism 2 also comprises and is positioned at pulping mechanism 3 (+X) first top roll 243 of side, with first top roll, the 243 opposite pulpboards 9 that make between first lower roll 244 between the two, be positioned at first top roll 243 (+X) second top roll 245 of side, and with second top roll, the 245 opposite pulpboards 9 that make between second lower roll 246 between the two.First top roll 243 and second top roll 245 by the opening 2410 (Fig. 3) in the upper plate 241 on (+Z) the main surface of side contacts pulpboard 9.First lower roll 244 and second lower roll 246 by the opening in the lower plate 242 on (Z) the main surface of side contacts pulpboard 9.First top roll 243 and second top roll, 245 pressurized frames are pressed to lower roll.
In pulp feed mechanism 2, first top roll 243 and second top roll 245 are respectively by being with 2481 and 2482 to be driven by motor 247 and 250 and to turn clockwise synchronously.First lower roll 244 and second lower roll 246 are connected to first top roll 243 and second top roll 245 by gear 2491 and 2492, and the rotation with first top roll 243 and second top roll 245 is rotated counterclockwise in Fig. 2, thereby the guiding respectively by upper plate 241 and lower plate 242 is transported to pulping mechanism 3 reposefully with pulpboard 9.In adsorption production manufacturing equipment 1, the operation of control pulping mechanism 3 is the rotating speeds (that is, the transporting velocity of pulpboard 9) according to motor 247, and rotating speed of motor is by control section 5 controls (below will go through this control).First lower roll 244 and second lower roll 246 can rotate with the motion of pulpboard 9 passively.
It is close to each other that the first pulverizing cylinder 312 and second is pulverized cylinder 322, the center line 91 of pipeline 24 (+Y) and (Y) side is symmetrical, and the clockwise direction that is driven at Fig. 2 by the cylinder rotating mechanism rotates, thereby the width of pulpboard 9 is pulverized whole pulpboard 9 relatively.Fig. 1 and Fig. 2 represent second disintegrating mechanism 32 (situation of Fig. 5 is identical therewith) seen from the direction of the parallel second titling axis line 321.
As shown in Figures 2 and 3, second pulverizes cylinder 322 comprises 30 pulverizing cuttves 33 arranging along the second titling axis line 321, and each pulverizes cutter 33 is disc substantially, with the second titling axis line 321 as the center, and perpendicular to the second titling axis line 321.Each is pulverized cutter 33 and comprises a plurality of teeth 331 (being 12 in this preferred embodiment), arranges by regular spaces on its excircle.Equally, first pulverizes cylinder 312 comprises 30 pulverizing cuttves 33 arranging along the first titling axis line 311, and each pulverizes cutter 33 is disc substantially, with the first titling axis line 311 as the center, and perpendicular to the first titling axis line 311.
To be expression second pulverize the external peripheral surface of cylinder 322 and near enlarged drawing thereof from what the direction that is parallel to the second titling axis line 321 was seen to Fig. 4.As shown in Figure 4, because 30 pulverizing cuttves 33 have tooth 331, these teeth 331 are along with near the center line 91 (referring to Fig. 3) of pipeline 24 in second direction of rotation of pulverizing cylinder 322 (promptly, the clockwise direction of Fig. 4) skew 1 degree, tooth 331 end portion are the external peripheral surface that the center is arranged in the second pulverizing cylinder 322 in a spiral manner with the second titling axis line 321, as shown in Figure 3.Equally, pulverize in the cylinder 312 first, the end portion of tooth 331 is that the center is arranged in first external peripheral surface of pulverizing cylinder 312 in a spiral manner with the first titling axis line 311, the tooth 331 that first tooth 331 and second of pulverizing cylinder 312 is pulverized cylinder 322 the center line 91 of pipeline 24 (+Y) side and (Y side) are symmetrical.
In pulping mechanism 3, pulverize cylinder 322 and rotate synchronously by belt pulley 313 and belt pulley 323 and not shown synchronous band respectively because first pulverizes cylinder 312 and second, pulpboard 9 is arranged in these teeth 331 orders of pulverizing on cylinder external peripheral surfaces and is pulverized by spiral way.Therefore, can prevent that these a large amount of teeth 331 of pulverizing on cylinders from contacting pulpboard 9 simultaneously, thereby put on the maximum of the active force of pulpboard 9 when reducing to pulverize.Since these pulverize tooth 331 on cylinders outside center line 91 1 side direction of pipeline 24 (promptly, along away from the direction of center line 91) sequentially contact pulpboard 9, pulpboard 9 is pulverized, therefore can be prevented to produce towards center line 91 and promote and the active force of crooked pulpboard 9 is also stably pulverized pulpboard 9.Because these teeth 331 of pulverizing on the cylinder contact pulpboard 9 symmetrically with respect to center line 91, pulpboard 9 is pulverized, therefore the active force that puts on pulpboard 9 is symmetrical with respect to center line 91, thereby can prevent that pulpboard 9 is along Y direction (perpendicular to the direction of carrying pulpboard 9) skew.
In adsorption production manufacturing equipment 1, as shown in Figures 2 and 3, the leading edge of upper plate 241 and lower plate 242 the center line 91 of pipeline 24 (+Y) side is abreast near first external peripheral surface of pulverizing cylinder 312, and center line 91 (Y) side is abreast near second external peripheral surface of pulverizing cylinder 322.When first pulverize cylinder 312 and second pulverize cylinder 322 rotations from (+Z) during side contacts pulpboard 9, the end portion 2421 of lower plate 242 is as supporting from (Z) side enters these support sections of pulverizing the pulpboard 9 of cylinder, resist the rotation that these pulverize the external peripheral surface of cylinder, the result guarantees to pulverize pulpboard 9.End portion 2421 with lower plate 242 is called " pulpboard support section 2421 " below.
When the pulverizing of pulpboard 9 is proceeded, the rearward end of pulpboard 9 ((+X) lateral edges) is through first top roll 243 and first lower roll 244, and when leaving pulp feed mechanism 2, the active force that pulpboard 9 is applied by first rotation of pulverizing the cylinder 312 and the second pulverizing cylinder 322 (moves pulpboard 9 towards (X) active force of direction pulling) pulpboard 9 automatically along throughput direction.
In pulping mechanism 3, as mentioned above, owing to have the first pulverizing cylinder 312 and the second pulverizing cylinder 322 that the throughput direction of relative pulpboard 9 tilts, therefore putting on the active force movement velocity of throughput direction (perhaps along) of pulpboard 9 along throughput direction, is these components that put on the active force (or movement velocity) of pulpboard 9 when pulverizing cylinders rotation along throughput direction.As a result, compare perpendicular to the situation of throughput direction, can reduce along the active force (or movement velocity) of throughput direction pulling pulpboard 9 with the rotation of pulverizing cylinder, and near the increase of pulpboard 9 movement velocitys can suppress to pulverize the pulpboard rearward end time.This has also suppressed to be transported in the unit interval number change of the pulpboard 9 of pulping mechanism 3 near pulpboard 9 rearward end, thereby can improve the quantity of the pulping of producing in the unit interval and the uniformity of quality thereof.
Because pulpboard 9 is pulverized tooth 331 orders of arranging in a spiral manner on cylinder 312 and the second pulverizing cylinder, 322 external peripheral surfaces by first and is pulverized, therefore can further reduce (promptly along the active force of throughput direction pulling pulpboard 9, prevent that big active force from putting on pulpboard 9 discontinuously), near the increase of pulpboard 9 transporting velocities in the time of more effectively inhibition pulverizing pulpboard 9 rearward end.
Because from (+Z) with (Z) the pulpboard leader 2411 of side contacts pulpboard 9 and pulpboard support section 2421 are pulverized the external peripheral surface of cylinders near these, even in the time of therefore near pulverizing pulpboard 9 rearward end, the pulpboard 9 that also can prevent to leave first top roll 243 and first lower roll 244 is because crooked or similar problem and do not pulverized and just be drawn into pulping mechanism 3, thereby guarantees that every pulpboard 9 can thoroughly pulverize.As a result, can improve the output of pulping.
In pulping mechanism 3, as shown in Figure 3, because pulverizing cylinder 322, the first pulverizing cylinder 312 and second tilts with respect to the direction of carrying pulpboard 9, therefore near the center line 91 at pipeline 24 between first disintegrating mechanism 31 and second disintegrating mechanism 32, have and the opposite stop 34 of pulpboard 9 leading edges of carrying and pulverizing along pipeline 24.If because some abnormal conditions increases near the transporting velocity of pulpboard 9 rearward end, then stop 34 contacts the leading edge of pulpboards 9, thereby mandatory reduction transporting velocity.As a result, even the transporting velocity of pulpboard 9 changes, can prevent that also the pulping that pulping mechanism 3 produces from becoming too thin, and keep the uniformity of pulping quality.
In adsorption production manufacturing equipment 1, for example, stack part 21 delays if cause pulpboard 9 to be fed to pulpboard for some reason, in order to prevent to stop for a long time 3 input pulpboards 9 to pulping mechanism, the slow down transporting velocity of pulpboard 9 of motor 247 that can be by reducing pulp feed mechanism 2 and 250 rotating speed.In this case, according to the rotating speed (that is, the transporting velocity of pulpboard 9) of motor 247, first of control section 5 controls first disintegrating mechanism 31 is pulverized second of the cylinder 312 and second disintegrating mechanism 32 and is pulverized cylinder 322, thereby reduces the rotating speed that these pulverize cylinder.As a result,, under the situation that does not stop 1 operation of adsorption production manufacturing equipment, can prevent that also the pulping of pulping mechanism 3 generations is too thin, keep the quality uniformity of pulping even the transporting velocity of pulpboard 9 changes.If the transportation lag of pulpboard 9 is higher than the rotating speed of motor 247 by the rotating speed that makes motor 250, the new pulpboard of carrying 9 can be caught up with last pulpboard 9, therefore improves the output of pulping.
The structure of adsorption production manufacturing equipment 1 in pulping mechanism 3 downstreams will be described below.The pulping that pulping mechanism 3 produces is transferred to adsorption production by pipeline 41 by not shown spraying and blowing organ and is formed mechanism 4, and the water absorbent polymer of carrying with polymer transport part 421 (for example, SAP (hypersorption polymer)) mixes, jet to tubulose absorption drum 42.Absorption drum 42 turns clockwise in Fig. 1, and the not shown attraction mechanism that utilize to connect its inboard is adsorbed onto its external peripheral surface with pulpboard and the water absorbent polymer of pulverizing, and wherein provides very little vacuum hole up to a predeterminated level.The absorption affinity required according to adsorption production 90 can be omitted the mixture of water absorbent polymer.
Be adsorbed onto the pulping of absorption drum 42 external peripheral surfaces and water absorbent polymer when absorption drum 42 rotates towards absorption drum 42 (Z) lateral movement, and transfer to from roll up 43 launch and by conveyer 401 towards (X) on the thin paper 92 that direction is carried.Binding agent (for example, hot melt) is applied to the upper surface of thin paper 92 in advance by binding agent supply section 431, the pulpboard of pulverizing and water absorbent polymer are combined on the thin paper 92, forms pulpboard layer 900.
Pulpboard layer 900 by conveyer 401 towards (when X) direction is carried, binding agent is applied to from another by binding agent supply section 441 and rolls up on the side of 44 thin papers 93 that launch, thin paper 93 is combined on pulpboard layer 900 and the thin paper 92 then, makes thin paper 92 have a side of binding agent towards pulpboard layer 900.Will be respectively from (Z) and (+Z) side by thin paper 92 and the 93 pulpboard layers 900 that twine by cutting part 471 cut into pieces 901 (below be called " absorbent core 901 ", because these fragments are used as the core of adsorption production 90), each fragment 901 has predetermined length, and a plurality of absorbent core 901 by conveyer 402 towards (X) direction is carried with preset space length.
Launch top flat 94 and egative film 95 from rolling up 45 and 46, binding agent is applied to their a corresponding side from binding agent supply section 451 and 461.Top flat 94 and egative film 95 are combined on the thin paper 92 and 93 of parcel absorbent core 901, and form adsorption production 90 by cutting part 472 cuttings of the gap location between the adjacent absorbent core 901.Then, unload the adsorption production 90 of manufacturing like this from adsorption production manufacturing equipment 1 by conveyer 403.
In adsorption production manufacturing equipment 1, as mentioned above, owing to improved the quantity and the quality thereof of the pulping that produces in the unit interval by pulping mechanism 3, so can improve the quality uniformity of adsorption production 90.If the rotating speed for transporting velocity that reduces pulpboard 9 and pulverizing cylinder is made such control, then control the operating rate of forming in the downstream and reduce in proportion.
Pulp crushing apparatus (pulp feed mechanism and pulping mechanism) according to second preferred embodiment will be discussed below.Fig. 5 and Fig. 6 amplify expression according to the part pipeline 24 of the pulp crushing apparatus of second preferred embodiment and the front view and the plane of pulping mechanism 3.In the pulp crushing apparatus of second preferred embodiment, pipeline 24 (X) side has as pressures partially the leading section of pulpboard 9 is pressed onto pulpboard pressing mechanism 26 on the pulpboard support section 2421.Component part except that above-mentioned and Fig. 1 be to shown in Figure 4 identical, and represent by identical Reference numeral.
As illustrated in Figures 5 and 6, pulpboard pressing mechanism 26 is between first disintegrating mechanism 31 and second disintegrating mechanism 32, (is positioned in this preferred embodiment on the center line 91) near the center line 91 of pipeline 24.Pulpboard pressing mechanism 26 comprises basic for cylindrical but terminally be conical pressing means 261, and pressing means 261 is contained on the support 263, can be around rotating shaft 262 rotations.In the pulp crushing apparatus in second preferred embodiment, have from (X) end of side is towards the (+X) breach 2412 that extends of side at the pulpboard leader 2411 of upper plate 241, and pressing means 261 is (X) in the breach 2412 of the tip portion of side insertion pulpboard leader 2411, relative with the pulpboard support section 2421 of lower plate 242.
In pulpboard pressing mechanism 26, pressing means 261 and support 263 (+Y) and (Y) side, torsionspring 264 is housed on the outside of rotating shaft 262, and an end portion of each torsionspring 264 from its winding part basically towards (+Z) direction is outstanding, another end portion is basically towards (X) direction is outstanding.Towards (+end portion contact that Z) direction is outstanding from support 263 towards (+Y) and (Y) axle 265 that direction is outstanding (X) side, towards (X) another end portion contact that direction is outstanding from pressing means 261 towards (+Y) and (Y) (+Z) side of the axle 266 that direction is outstanding.
Owing to torsionspring 264 is compressed on the direction near another end portion that contacts with axle 265 in Fig. 5 clockwise in the end portion that contacts with axle 266, therefore (Z) depress by direction by the thrust of torsionspring 264 court for axle 266.The result, produced the active force that the counter clockwise direction of pressing means 261 in Fig. 5 rotated around rotating shaft 262, thereby pressing means 261 (X) between the tip portion of side and the pulpboard support section 2421, ((X) end portion of side) is pressed onto on the pulpboard support section 2421 pressing means 261 with the leading section of pulpboard 9.
Have two pins 267 that extend along the Z direction on the support 263, pin 267 (Z) tip of side axle 266 (+Z) have little gap (for example, apart from the diameter wiry that forms torsionspring 264 no better than) between side and the axle 266.In the pulp crushing apparatus of second preferred embodiment, though pressing means 261 (X) tip portion of side is acted on impact on the pulpboard 9 along the upspringing clockwise of Fig. 5 in pulpboard 9 crushing process, axle 266 towards (+Z) motion of side also can be controlled by pin 267.
In the pulp crushing apparatus of second preferred embodiment, as first preferred embodiment, pulping mechanism 3 comprises first disintegrating mechanism 31 and second disintegrating mechanism 32 that is parallel to pulpboard 9 widths (Y direction) arrangement, and first disintegrating mechanism 31 and second disintegrating mechanism 32 comprise that respectively first pulverizes the cylinder 312 and the second pulverizing cylinder 322, are used to pulverize the pulpboard 9 that enters external peripheral surface.It is close to each other that the first pulverizing cylinder 312 and second is pulverized cylinder 322, (+Y) side and (Y) side is symmetrical at the center line 91 of pipeline 24, and along with first rotation of pulverizing the cylinder 312 and the second pulverizing cylinder 322, (+Y) is with (Y) the part pulpboard 9 of side is pulverized, and pulverizes pulpboard 9 at whole width then.
The first titling axis line 311 and the second titling axis line 321 are corresponding rotations that the first pulverizing cylinder 312 and second is pulverized cylinder 322, and every titling axis line leaves the far-end of center line 91 towards pulp feed mechanism 2 inclinations.The first titling axis line 311 and the second titling axis line, 321 (see figure 3)s are with respect to center line 91 symmetries of pipeline 24, and the angle between every titling axis line and the center line 91 is not less than 30 degree and is not more than 60 degree (being 45 degree) in this preferred embodiment.
In the pulp crushing apparatus of second preferred embodiment, as first preferred embodiment, proceed when pulverizing pulpboard 9, the rearward end of pulpboard 9 ((+X) lateral edges) (see figure 2) during through first top roll 243 of pulp feed mechanism 2 and first lower roll 244, pulpboard 9 is pulverized cylinder 312 and second first and is pulverized under the rotation of cylinder 322 automatically along (X) direction motion.
In pulping mechanism 3, as first preferred embodiment, because pulverizing cylinder 322, the first pulverizing cylinder 312 and second tilts with respect to pulpboard 9 throughput directions, therefore compare perpendicular to the situation of throughput direction with the rotation of pulverizing cylinder, can reduce along the active force (or movement velocity) of throughput direction pulling pulpboard 9, and the movement velocity of pulpboard 9 increases can further suppress to pulverize near pulpboard 9 rearward end time.This also can be suppressed at pulpboard 9 rearward end and be transported to the number change of the pulpboard 9 of pulping mechanism 3 near the unit interval, thereby can increase the quantity and the quality uniformity thereof of the pulping that produces in the unit interval.
As first preferred embodiment, pulverize the transporting velocity (referring to Fig. 2) that the movement velocity of the pulpboard 9 of cylinder 322 pullings is lower than pulp feed mechanism 2 owing to pulverized cylinder 312 and second by first, last pulpboard 9 is after through first top roll 243 and first lower roll 244, back one pulpboard 9 promote its rear end subordinates according to be transported to pulping mechanism 3 through the identical speed of the speed before these rollers, and in this pulverizing.Therefore, pulpboard 9 can be transported to pulping mechanism 3 by constant speed always, thereby can keep the quantity uniformity of the pulping of generation in the unit interval always.
Because from (+Z) and (Z) the pulpboard leader 2411 of side contacts pulpboard 9 and pulpboard support section 2421 are in first and pulverize near the external peripheral surface of the cylinder 312 and the second pulverizing cylinder 322, even when pulverizing the rearward end of pulpboard 9, can prevent that also the pulpboard 9 that leaves first top roll 243 and first lower roll 244 is not drawn into pulping mechanism 3 by pulverizing, thereby guarantee thoroughly to pulverize pulpboard 9.
In the pulp crushing apparatus of second preferred embodiment, particularly, pulpboard 9 is pressed onto on the pulpboard support section 2421 in very close first position (that is last part of carrying of pulpboard 9 rearward end) of pulverizing the cylinder 312 and the second pulverizing cylinder 322 by pulpboard pressing mechanism 26 away from pulp feed mechanism 2.Therefore, the rearward end of pulpboard 9 remains between pulpboard pressing mechanism 26 and the pulpboard support section 2421, and before just being transported to pulping mechanism 3, thereby can guarantee to prevent is not drawn into pulping mechanism 3 by pulverizing near the rearward end of pulpboard 9.As a result, in the pulp crushing apparatus of second preferred embodiment, can guarantee thoroughly to pulverize pulpboard 9.
In the pulp crushing apparatus of second preferred embodiment, pressing means 261 is not to be necessary for substantially cylindrical, for example, can use the polygon cylindrical member as pressing means.In this case, from pulverizing the position of cylinder 322 and guarantee and thoroughly push down near pulpboard 9 rearward end viewpoint very pulverizing cylinder 312 and second near first, preferably, (X) tip portion of the pressing means of side should have the cusp configuration as pyramid.
Though the preferred embodiments of the present invention have been discussed above, and the present invention is not limited to above-mentioned preferred embodiment, but allow different variations.
For example, angle between every first titling axis line 311 and the second titling axis line 321 and the center line 91, according to the kind of pulverized pulpboard 9 and transporting velocity, required quality uniformity or the conditions of similarity of pulverizing pulpboard, can be greater than 0 with less than a suitable numerical value between 90 degree.But from suppressing near the transporting velocity increasing angles of pulping mechanism 3 pulpboard 9 when Y direction width dimensions increases and pulverize pulpboard 9 rearward end, preferred angle should be not less than 30 degree and be not more than 60 degree.
First pulverizes cylinder 312 and second pulverizes cylinder 322 unnecessary center line 91 symmetric arrays with respect to pipeline 24, but, for example, in order to guarantee that near the part of pulpboard 9 center line 91 of pipeline 24 pulverized, can adopt such arrangement, be about to these positions of pulverizing cylinder along directions X (throughput direction) skew, and make one (or two) pulverizing cylinder stride across center line 91.
In pulping mechanism 3,, can provide other pulverizing cylinder though pulpboard 9 can pass through close to each other and pulverize cylinder 322 with respect to the center line 91 symmetrically arranged first pulverizing cylinders 312 and second of pipeline 24 and stably pulverize.For example, as shown in Figure 7, between the first pulverizing cylinder 312 and the second pulverizing cylinder 322, pulverize cylinder 35 and be arranged on the center line 91 of pipeline 24, thereby use three pulverizing cylinders to pulverize whole pulpboard 9 at its width with the 3rd.
In pulp crushing apparatus, for example, the web-like pulpboard that is wrapped on the drum can be launched and is transported in the pulping mechanism 3.
Though it is detailed icon and illustrated that the present invention, above-mentioned explanation are indicative in all respects, rather than restrictive.Therefore, it should be understood that under the situation that does not depart from scope of the present invention and can design many modifications and variations.
