As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 3, the waste smoke winnowing device 14 according to one embodiment of the present invention includes a wind box 142, a blowing device 144 and a first partition 146.

The first partition 146 is disposed in the bellows 142, and divides the inner cavity of the bellows 142 into a first winnowing cavity 141, a second winnowing cavity 143, and a winnowing channel 145 communicating the first winnowing cavity 141 and the second winnowing cavity 143. The air box 142 is provided with a feed inlet 158 for feeding from the first air separation cavity 141, and an airflow port of the blowing device 144 is arranged towards the feed inlet 158. When the waste smoke winnowing device 14 is in an operating state, the air flow direction flows through the winnowing channel 145 along the feeding direction and enters the second winnowing cavity 143.

During the air separation process, the air flow opening of the blower 144 is oriented toward the inlet 158 such that the air flow of the air separation follows a path, specifically in one embodiment, in direction E as shown in fig. 3. In this manner, the rejects/waste tobacco that falls into the windbox 142 from the inlet 158 is blown away by the winnowing air flow. Because the inner cavity of the air box 142 is circumferentially closed, after the inferior/waste cigarettes are blown away by the winnowing airflow, the winnowing airflow continues to flow along the winnowing channel 145 to drive the inferior/waste cigarettes to flow along the winnowing channel 145. The defective/waste cigarettes in various states fall faster due to the heavier weight, and the first partition plate 146 plays a role of blocking, so that the defective/waste cigarettes in various states are blocked and fall into the first air separation cavity 141. The tobacco shreds, the paper sheets and the like are relatively light and have relatively low falling speed, and the tobacco shreds, the paper sheets and the like continuously move along the air separation channel 145 without being blocked by the first partition plate 146 to fall into the second air separation cavity 143, so that the air separation of defective/waste cigarettes is realized, the air separation effect is good, the production efficiency is high, and the cost is low.

In one embodiment, a second baffle 148 is disposed in the bellows 142 in spaced relation to the first baffle 146, and the feed opening 158 is disposed in the space between the first baffle 146 and the second baffle 148. Specifically, the first partition plate 146 and the second partition plate 148 are disposed in the inner cavity of the bellows at intervals along a predetermined direction to form a first winnowing cavity 141 and a second winnowing cavity 143 arranged along the predetermined direction, and a winnowing channel 145 respectively communicating the first winnowing cavity 141 and the second winnowing cavity 143.

More specifically, the first partition 146 and the second partition 148 are disposed at intervals from right to left along the lengthwise extension direction of the bellows 142, and divide the inner chamber of the bellows into three chambers. The first separator 146, the second separator 148 and the inner wall of the inner cavity of the bellows form a first air separation cavity 141, and the second separator 148 and the inner wall of the inner cavity of the bellows form the second air separation cavity 143. The blower 144 is disposed in the inner chamber of the windbox and is located substantially above the chamber formed between the first baffle 146 and the inner wall of the inner chamber of the windbox, i.e., the chamber to the right as viewed in FIG. 3.

It should be understood that in actual production and manufacture, the one end of the bellows has an opening in consideration of the cost and the manufacturing difficulty of the bellows, and the installation difficulty of the blowing device. Therefore, in order to prevent the collected cigarettes and/or a small amount of cut tobacco and paper scraps from floating out of the air box, the second partition plate 148 is arranged, so that the cigarettes are convenient to collect, and the environment is ensured not to be polluted. Of course, in other embodiments, the second partition 148 may be omitted, and is not limited herein. Note that the predetermined direction is a longitudinal extending direction of the bellows 142, and as shown in fig. 3, in one embodiment, the bellows 142 has a substantially rectangular parallelepiped shape, and the predetermined direction is a left-right direction shown in the drawing.

In one embodiment, the feed port 158 is disposed at the top of the windbox 142. Thus, the cigarette and/or a small amount of cut tobacco and paper scraps have enough falling time after entering from the feeding hole 158, and are convenient for more accurate winnowing. Specifically, this feed inlet is located first baffle 146 with in the interval between the second baffle 148, also follow first selection by winnowing cavity 141 and feed, blast apparatus 144 sets up in an end of bellows 142, and the relative lengthwise extending direction tilt up of bellows 142 of direction of blowing to when cigarette gets into bellows 142, make the selection by winnowing air current blow to the cigarette, and make the cigarette remove along selection by winnowing passageway 145, realize the selection by winnowing of cigarette. More specifically, the blowing device 144 is disposed obliquely upward relative to the longitudinal extension direction of the air box 142, and is located at a side of the feeding port 158 away from the second partition 148, and the air flow port thereof is generally aligned with the position where the cigarettes fall from the feeding port 158 of the air box 142, as a preferred embodiment, the angle between the blowing device 144 and the longitudinal extension direction of the air box 142 is 0-60 degrees, preferably 45 degrees.

In one embodiment, the first partition 146 and the bellows 142 extend lengthwise perpendicular to each other. Specifically, the first partition plate 146 and the second partition plate 148 are vertically connected to the bottom of the bellows 142 and are arranged in parallel along the longitudinal extension direction of the bellows 142, so that the partition plates have a good blocking effect, and the air separation is performed more accurately. More specifically, if the first partition 146 and the second partition 148 are inclined at an angle with respect to the longitudinal extension of the air box 142, a portion of the cut tobacco and the paper sheet will fall into the first air separation chamber 141 without being separated by the partitions, and therefore, in a preferred embodiment, the first partition 146 should be perpendicular to the flow direction of the air flow along the air separation channel 145.

In one embodiment, the height of the first partition 146 is greater than the height of the second partition 148. Specifically, the cigarettes fall into the bellows 142 from the feeding port 158, and under the action of the blowing device 144, the cigarettes move along the passage of the bellows 142, and the first air separation cavity 141 and the second air separation cavity 143 respectively accommodate the air-separated cigarettes and at least one of the cut tobacco and the paper scraps. The first partition 146 is higher than the second partition 148 to prevent the cigarettes entering the first air separation chamber 141 from falling into the right side chamber of the first partition 146, i.e. the chamber below the blowing device 144. In a preferred embodiment, the first partition 146 is at a height approximately flush with the bottom of the blower 144, and the bottom of the chamber defined by the first partition 146 and the inner wall of the bellows chamber is provided with a collection device 156 for collecting a small amount of cigarettes, tobacco and/or paper scraps that may be present therein.

It should be understood that when the defective/waste cigarette falls into the air box 142 from the inlet 158 of the air box 142, due to the difference between the windward area and the density of the cut tobacco and the shredded paper and the waste cigarette in the cigarette receiving state, the cut tobacco and the shredded paper will be blown out to a greater distance and fall into the second air separation cavity 143 which is further away from the blowing device 144 under the action of the air separation flow, and the waste cigarette in the cigarette receiving state will fall into the first air separation cavity 141 to a lesser extent. The above-mentioned winnowing effect is a better winnowing effect, and certainly, the distribution of the cut tobacco scraps and the waste tobacco branches in the rolling and connecting state falling into the first winnowing cavity 141 or the second winnowing cavity 143 is not absolute, that is, a small amount of cut tobacco and scraps may fall into the first winnowing cavity 141, and a small amount of waste tobacco branches in the rolling and connecting state may fall into the second winnowing cavity 143.

To further enhance the air separation effect, in one embodiment, the waste smoke air separation device 14 further includes an adjusting plate 147, and the adjusting plate 147 is installed on one side of the second partition 148 and is adjustable in position relative to the second partition 148. Specifically, the adjusting plate 147 is detachably mounted on a side of the second partition 148 facing the first partition 146, and has an adjustable height, so as to adjust the blocking of the cigarettes, tobacco shreds and/or paper scraps moving along the air separation channel 145 along with the air separation flow, thereby further improving the air separation effect. For example, if the height of the adjusting plate 147 is higher, the amount of the waste tobacco falling into the first winnowing chamber 141 in the rolled state is smaller, and the amount of the cut tobacco and the paper scrap falling into the second winnowing chamber 143 is increased. When the height of the adjusting plate 147 is lower, the amount of the waste tobacco falling into the first winnowing cavity 141 and the amount of the cut tobacco and the paper scrap falling into the second winnowing cavity 143 are opposite to the above-mentioned situation, and will not be described herein again. Specifically, in one embodiment, a mounting hole may be formed in the second partition 148 along the vertical direction, that is, in the height direction of the second partition 148, and the adjusting plate 147 is mounted on the second partition 148 through the mounting hole, so that the height of the adjusting plate 147 is adjustable.

Further, in order to adjust the air separation effect, the adjusting plate 147 is rotatably installed at one side of the second partition 148. In the foregoing embodiment, the adjusting plate 147 may be hinged to the mounting hole by a pivot shaft to be rotatably coupled to the second partition 148.

It should be understood that the position of the adjusting plate 147 relative to the second partition 148 is not limited to the two adjusting manners, and for example, the position is also adjustable in the direction perpendicular to the longitudinal extension direction of the air box 142, i.e., in the direction perpendicular to the paper as shown in fig. 3.

In one embodiment, the blowing device 144 further comprises a flow guide plate 149, the flow guide plate 149 is located between the feeding hole 158 and the air flow port of the blowing device 144, and the lower end of the flow guide plate 149 faces the second air separation cavity 143. In particular, the guide plate 149 is arranged at one side edge of the feed opening 158 close to the blowing device 144, i.e. at the right side edge as viewed in fig. 3, and extends obliquely in a direction away from the blowing device 144, i.e. in the flow direction of the winnowing gas flow, towards the second winnowing chamber 143. Therefore, the winnowing airflow can be guided, so that the defective/waste cigarettes entering the inner cavity of the air box from the feeding hole 158 of the air box 142 selectively fall into the first winnowing cavity 141 and the second winnowing cavity 143 under the blowing of the guided winnowing airflow, and the winnowing effect is improved.

It should be noted that, since the principle of air separation is to utilize the difference between the windward areas and the densities of different materials for air separation, the blowing device 144 needs to be generally aligned with the feeding port 158 for obtaining a better air separation effect. However, in order to have sufficient time for the defective/waste cigarette to fall, i.e., move along the air separation channel 145, the feed opening 158 is preferably located at the top of the windbox 142. Therefore, the guide plate 149 extends obliquely toward the second air separation cavity 143 along a direction away from the blowing device 144, so that the air separation airflow flows obliquely toward the first air separation cavity 141 and the second air separation cavity 143, thereby improving the air separation effect and preventing the air separation airflow from being too dispersed to affect the air separation effect.

In one embodiment, the angle of the blower 144 relative to the inlet 158 is adjustable. Specifically, the blowing device 144 is movably connected to the air box 142 to adjust an angle between the blowing device 144 and the feeding port 158. In one embodiment, the blowing device 144 is hinged to the air box 142 to adjust the angle of the blowing device 144 relative to the feeding opening 158, so that the air flow direction of the air separation can be adjusted by adjusting the angle of the blowing device 144 relative to the feeding opening 158, the air flow size of the cigarettes entering the feeding opening 158 can be adjusted, different types of cigarettes can be separated, and the universality of the air separation is improved.

It should be understood that in other embodiments, the blower 144 is movably coupled to the blower 142, and can be moved relative to the feed opening 158, for example, but not limited to, along a guide slot, to further facilitate adjustment. It should also be understood that the blowing device 144 may be mounted to the bellows 142 without limitation, such as by a bracket extending into the bellows 142 or other connection.

In one embodiment, the waste tobacco winnowing device 14 further comprises a receiving hopper 150, and the receiving hopper 150 is disposed at the feeding port 158 of the wind box 142 to receive the tobacco rods falling into the receiving hopper 150. Specifically, the hopper 150 includes an open end and a discharge end communicating with the feed opening 158 of the bellows 142, and the hopper 150 includes a guide surface as an inner wall of the hopper 150, the guide surface being disposed obliquely with respect to the open end and the discharge end. Therefore, the cigarettes falling into the material receiving hopper 150 have a buffering process, so that the cigarettes can uniformly enter the air box 142 for air separation, and the air separation effect is improved.

In one embodiment, the waste smoke winnowing device 14 further includes a first material receiving hopper 152 and a second material receiving hopper 154, the first material receiving hopper 152 is communicated with the discharge port of the first winnowing cavity 141, and the second material receiving hopper 154 is communicated with the discharge port of the second winnowing cavity 143. Thus, under the action of the air current, the waste cigarette in the rolling state falls into the first air separation cavity 141 and falls into the first receiving hopper 152 from the discharge port of the first air separation cavity 141, so that the waste cigarette sorting mechanism 16 can perform sorting in the next step. The cut tobacco and the paper scrap fall into the second winnowing cavity 143 and fall into the second receiving hopper 154 from the discharge port of the second winnowing cavity 143 to collect the cut tobacco, the paper scrap and the like.

Based on the above-mentioned waste cigarette winnowing device 14, as shown in fig. 1 and fig. 2, the present invention further provides a cigarette sorting system 10, wherein the cigarette sorting system 10 further includes a lifting device 12 and a waste cigarette sorting mechanism 16.

In one embodiment, the elevator 12 includes a feed end 122 and a discharge end 124, the waste tobacco separator 14 is disposed below the discharge end 124 of the elevator 12, and the waste tobacco sorting mechanism 16 is disposed below the discharge outlet of the waste tobacco separator 14. The lifting device 12 is used for lifting defective/waste cigarettes to a certain height, the waste cigarette winnowing device 14 is used for winnowing the defective/waste cigarettes conveyed by the lifting device 12, so that cut tobacco and lighter paper scraps are separated out, cigarettes with heavier weight fall into the waste cigarette sorting mechanism 16, and the waste cigarette sorting mechanism 16 is used for arranging the winnowed defective/waste cigarettes along the conveying direction of the waste cigarette sorting mechanism 16 and sorting out cigarettes with preset length ranges, such as filter tips, broken cigarettes, bent cigarettes, double-mouth cigarettes and non-filter cigarettes.

It should be understood that the transfer of the cigarettes between the elevator 12 and the waste tobacco winnowing device 14, and between the waste tobacco winnowing device 14 and the waste tobacco sorting mechanism 16, is effected by the gravity of the cigarettes. In other embodiments, however, the conveying may be performed by other means, such as a conveyor belt, which may increase the cost compared to the gravity conveying, but should not be construed as a factor limiting the scope of the present invention.

In one embodiment, the lifting device 12 includes a driving wheel 126, a driven wheel 128, and a transmission belt 129 connected between the driving wheel 126 and the driven wheel 128, the transmission belt 129 extends obliquely upward at an angle with respect to the horizontal direction, and the lifting device 12 further includes lifting plates 123, and the lifting plates 123 are disposed at intervals along the extending direction of the transmission belt 129. Thus, the defective/waste cigarettes are placed on the conveyor belt 129 from the feed end 122 of the lifting device 12, and because the conveyor belt 129 is inclined upward at an angle relative to the horizontal, the lifting plate 123 acts as a support and prevents the cigarettes from sliding downward, thereby lifting the cigarettes to the discharge end 124 of the lifting device 12. Wherein, the contained angle of conveyer belt 129 relative horizontal direction is 5 degrees ~70 degrees, preferably 60 degrees.

Specifically, a driving wheel 126 is disposed at the top (discharge end 124) of the lifting device 12, a driven wheel 128 is disposed at the bottom (feed end 122) of the lifting device 12, the driving wheel 126 is driven by a motor 125, and a conveyor belt 129 is respectively sleeved on the driving wheel 126 and the driven wheel 128 in a tensioning manner to circularly move forward under the rotation of the driving wheel 126. The lifting device 12 further comprises a feeding hopper 121, the feeding hopper 121 is disposed at the feeding end 122 of the lifting device 12, in the practical operation process, the defective/waste cigarettes are poured into the feeding hopper 121, the conveyor belt 129 circularly moves forward under the rotation of the driving wheel 126, and the cigarettes are lifted to the discharging end 124 of the lifting device 12 under the action of the lifting plate 123.

Further, the lifting plates 123 are the same in height and are disposed at regular intervals in the extending direction of the conveyor belt 129. Specifically, the lifting plates 123 are substantially vertically arranged on the conveying surface of the conveying belt 129 and are spaced at a certain distance, so that the cigarette quantity lifted by each lifting plate 123 is certain due to the same height of the lifting plates 123 and the certain spacing between the adjacent lifting plates 123, and therefore, the purpose of uniformly lifting cigarettes can be achieved when the cigarettes are poured into the feeding hopper 121, and the waste cigarette winnowing device 14 can perform winnowing conveniently.

In one embodiment, referring to fig. 2, 4 and 5, the waste smoke sorting mechanism 16 includes a vibratory sorting device 162 and a length sorting device 164, wherein the length sorting device 164 is connected to one end of the vibratory sorting device 162 along a feeding direction of the vibratory sorting device 162. The vibrating sorting device 162 includes a vibrating machine 1622 and an arrangement portion 1626 disposed on the vibrating machine, the arrangement portion 1626 is configured to longitudinally arrange the cigarettes along a feeding direction, and the length sorting device 164 is configured to sort the cigarettes within a predetermined length range from the arranged cigarettes.

So, through the range of vibration sorting unit 162 to divide through length sorting unit 164 and elect the cigarette that predetermines the length scope, can with the band filter, comparatively complete cigarette is selected out from defective/waste cigarette branch, and does not need manual operation, degree of automation is high, and it is good to select separately the effect.

In one embodiment, the waste smoke sorting mechanism further includes a sieving portion 1624, the sieving portion 1624 and the arrangement portion 1626 are sequentially arranged on the vibrating machine 1622 along the feeding direction, the sieving portion 1624 includes a sieving plate, a plurality of sieve holes 1628 (see fig. 6) are formed on the sieving plate, and a filtering cavity 1629 is formed between the sieving plate and the vibrating machine 1622. Specifically, the screening board is a rectangular flat board, a plurality of sieve holes 1628 which are at least one of circular, kidney-shaped and rectangular are arranged on the screening board, and a filtering cavity 1629 is formed between the screening board and the supporting surface of the vibrating machine 1622 and is used for filtering exposed cut tobacco or fine cigarettes or cigarette paper fragments mixed in the waste cigarettes. A funnel (not shown) is further provided at the bottom of the filtering cavity 1629 to collect at least one of cut tobacco, fine tobacco rods, and tobacco paper fragments collected in the filtering cavity 1629. Therefore, sundries such as tobacco shreds, small paper scraps and the like which pass through the air separation field are further sorted and cleaned, so that the impurities in the cigarettes entering the arrangement part 1626 are reduced and the corresponding requirements are met.

It will be appreciated that the sifting portion 1624 is not required, that is, in other embodiments, only the arrangement 1626 may be provided without the sifting portion 1624.

It should be noted that the vibrating machine 1622 is well known in the art, and the detailed structure and principle thereof will not be described herein since it can be obtained by those skilled in the art according to the conventional art. As a preferred embodiment, the vibrating machine 1622 may be a linear vibrating machine 1622, and may be a mechanical linear vibrating machine 1622, a motor driven linear vibrating machine 1622, or an electromagnetic force driven linear vibrating machine 1622.

In one embodiment, the vibratory sorting device 162 further includes a receiving portion 1621, the receiving portion 1621 being disposed on the vibrating machine 1622 and located at an end of the arrangement portion 1626 remote from the length sorting device 164. Specifically, the receiving portion 1621 is located below the first receiving hopper 152 of the waste tobacco winnowing device 14 to receive cigarettes winnowed by the wind in the first winnowing cavity 141, and the sieving portion 1624 is located at the rear end of the receiving portion 1621. It should be understood that the receiving portion 1621 is not open to the screen opening 1628, but the cigarettes may be conveyed in the feeding direction at the receiving portion 1621 to the screening portion 1624 for sorting. In one embodiment, receiving portion 1621 includes a receiving plate, and receiving portion 1621 is angled relative to screening portion 1624 to facilitate transporting received cigarettes to screening portion 1624.

Therefore, in the process that the cigarette moves along the conveying direction under the action of the vibrating machine 1622, the cigarette within the preset length range is sorted out through the first leaking groove 1641, the second leaking groove 1643 and the third leaking groove 1645.

In one embodiment, the widths of the plurality of discharge chutes increase sequentially along the feeding direction. Specifically, the widths of the first leaking groove 1641, the second leaking groove 1643 and the third leaking groove 1645 are sequentially increased, and when the waste cigarette moves from the guide plate 1625 of the arrangement portion 1626 to the first sorting section 1644, cigarettes with smaller lengths are sorted by the first leaking groove 1641, for example, filters, non-filter cigarettes, broken cigarettes, and the like. When the waste cigarette is conveyed to the second sorting section 1646, the cigarettes with shorter length are further sorted out, and when the waste cigarette is conveyed to the third sorting section 1648, the more complete waste cigarette, namely the cigarettes with longer length are sorted out by the third leaking groove 1645. In this way, through the sorting of three sections, the cigarette of different length is separated and collected.

It will be appreciated that the number of sorting sections and the width of the aforesaid chutes may be determined according to the actual situation, for example, a plurality of sorting sections may be included, and the widths of some chutes in the middle may be equal, so as to realize multiple sorting, but it should be avoided that the width of the chute positioned at the front is not too large, so that the cigarettes may not drop down by sorting layers.

The length sorting device 164 may be a conveyor belt 129 or the linear vibrator 1622 described above, and in short, the cigarettes arranged by the arrangement portion 1626 may be conveyed in the conveying direction.

In one embodiment, the length sorter 164 further includes a divider mechanism including a plurality of baffles 1647, the baffles 1647 being disposed in the sorting section and extending generally in the feeding direction with adjacent baffles 1647 being spaced apart. Specifically, baffle 1647 sets up along defeated material direction parallelly to each other, and along length sorting unit 164's width direction, the same distance setting of the upper and lower direction interval as shown in fig. 10 promptly, so, make cigarette when moving along first sorting section 1644, second sorting section 1646 and third sorting section 1648, the condition that a large amount of cigarettes overlap can not appear, reduce the interference between cigarette and the cigarette to improve the sorting effect.

It will be appreciated that in other embodiments, the baffles 1647 may not be parallel to each other and may move in the feeding direction, but it should be noted that the angle between the baffles and the feeding direction is not too large to affect the sorting of the cigarettes. In one embodiment, the waste sorting mechanism 16 further includes a collector located below the chute to collect the sorted cigarettes.

Based on the cigarette sorting system 10, the invention also provides a cigarette sorting method, which comprises the following steps:

conveying the defective/waste tobacco branches to a waste tobacco winnowing device 14 for winnowing through a lifting device 12;

specifically, the cigarettes poured from the feeding hopper 121 are lifted to the discharging end 124 of the lifting device 12 by the lifting plate 123 and dropped into the receiving hopper 150 of the waste cigarette winnowing device 14 by being circularly moved upward by the conveyor belt 129, and are winnowed by the waste cigarette winnowing device 14.

The cigarettes after air separation are further screened by the screening part 1624 and are arranged on the arrangement part 1626 lengthways along the material conveying direction;

specifically, under the action of the vibrating machine 1622, the cigarettes collected by the first receiving hopper 152 and falling to the sieving section are conveyed along a preset direction, and the exposed cut tobacco or the fine cigarettes or the cigarette paper fragments mixed in the cigarettes are further sorted out. And are arranged in rows one by one in the arrangement portion 1626 along the longitudinal direction of the guide slot 1630.

The cigarettes arranged lengthwise along the feeding direction are conveyed to the length sorting device 164 and sorted out within a predetermined length range.

Specifically, the arranged cigarettes are conveyed to the length sorting device 164, and the cigarettes in the preset length range are sorted layer by layer through the leakage grooves.

In the waste cigarette sorting mechanism 16 and the cigarette sorting system 10, the blowing device 144 is disposed toward the feeding port 158 during the air separation process, and the defective/waste cigarettes falling into the air box 142 from the feeding port 158 are blown away by the air flow of the air separation. Because the inner cavity of the air box 142 is circumferentially closed, after the defective/waste cigarettes are blown away by the winnowing airflow, the winnowing airflow continues to flow along the winnowing channel 145 to drive the defective/waste cigarettes to flow along the winnowing channel 145. The defective/waste cigarettes in various states fall faster due to the heavier weight, and the first partition plate 146 plays a role of blocking, so that the defective/waste cigarettes in various states are blocked and fall into the first air separation cavity 141. The tobacco shreds, the paper sheets and the like are relatively light and have relatively low falling speed, and the tobacco shreds, the paper sheets and the like continuously move along the air separation channel 145 without being blocked by the first partition plate 146 to fall into the second air separation cavity 143, so that the air separation of defective/waste cigarettes is realized, the air separation effect is good, the production efficiency is high, and the cost is low. In addition, through the screening and the range of vibration sorting unit 162 to divide through length sorting unit 164 and elect the cigarette that predetermines the length scope, can with the filter tip, comparatively complete cigarette is selected out from defective/waste cigarette, and does not need manual operation, degree of automation is high, and it is good to select separately the effect.
