Detailed Description
Referring to fig. 1 and 2, the intelligent detection system for winding the chopped strand mats is mainly used for intelligently picking broken needles mixed in the chopped strand mats before a winding station and preventing the broken needles from entering a winding bag.
The method specifically comprises the following steps:
the feeding part 1 is positioned at the rear part of the drying station and is used for guiding the chopped strand mats and consists of a pair of extrusion paired rollers.
And the discharging part 5 is positioned at the front part of the winding station and is used for guiding out the chopped strand mats and consists of a pair of extrusion paired rollers. A console 6 is arranged at one side of the discharging part 5, and a control unit is arranged in the console.
The feeding part 1 is higher than the discharging part, a detection area is arranged between the feeding part 1 and the discharging part, the detection area comprises two side supports which are symmetrically arranged, the two side supports are obliquely arranged between the feeding part 1 and the discharging part 5 along the transmission direction of the chopped strand mats, and the area between the two side supports is divided into a front detection area 2, a vibration detection area 3 and a rear detection area 4 from top to bottom. The front detection area 2 is used for sucking out the needle at the upper part of the chopped strand mat, the oscillation detection area 3 is used for sucking out the needle at the lower part of the chopped strand mat, and the rear detection area 4 is used for re-detection.
Looking first at the front detection zone 2, it specifically comprises:
a first bottom support 21, arranged between the upper parts of the two side supports, is used for chopped strand mat transport. The specific structure of the first bottom support 21 will be described below with reference to fig. 7.
The first bottom support 21 comprises a first bottom plate 211 connected to the upper surfaces of the two side supports, and an extension part is arranged on one side close to the feeding part 1.
The upper beam 212 is fixed at the position of the first bottom support 21 close to the top end of the side support, a first height adjusting piece 213 is arranged on one side of the feeding portion 1 facing the front detection area 2, and the upper beam 212 is clamped in the height adjusting piece 213. Thus, the upper supporting point position of the whole detection area can be adjusted, and the inclination of the detection area can be adjusted by matching with the height adjusting piece of the rear detection area 4.
A first metal detector 22 is disposed transversely above the chopped strand mat conveying surface for detecting the presence of metal objects, such as needles, in the web passing thereunder.
A first electromagnet 24 is disposed transversely above the chopped strand mat transport surface behind the first metal detector 22.
The first electromagnet 24 has a rectangular structure, and the bottom surface is arranged parallel to the first bottom support 21.
The first metal detector 22 and the first electromagnet 24 are both connected with the control unit, and when the control unit receives a signal fed back by the first metal detector 22, the first electromagnet 24 is controlled to be electrified.
The arrangement of the first electromagnet 24 is described below in connection with fig. 9.
The first electromagnet 24 is supported above the chopped strand mat transport surface by two side supports, two oppositely disposed side brackets 23.
The side bracket 23 includes a U-shaped holding frame 231 with an opening facing upward, the upper portion of which is used for the first electromagnet 24 to be placed in, and the bottom of which is provided with a height adjusting member 232 for adjusting the height of the first electromagnet 24.

The height of the supporting plate can be adjusted by rotating the handle.
Since the first electromagnet bottom surface is arranged parallel to the first bottom support 21, the side supports must also be arranged obliquely, resulting in a center back, and therefore triangular reinforcement 233 is also provided on the side support behind the side support 23, connected thereto.
Since the needles are all adsorbed at the bottom of the first electromagnet 24 and the detection area is wide, it is very difficult to manually clean the needles adsorbed at the intermediate position, and therefore, the first needle retracting device 25 is also provided to solve this problem.
Referring to fig. 3-6, a first needle retraction device 25 is provided below the first electromagnet 24 for collecting the needles adsorbed below the first electromagnet 24.
As one embodiment, the first narrowing means 25 specifically includes:
the fixed seats 251 are respectively positioned outside the two side brackets 23 which are oppositely arranged;
the first sliding rod group 252 is positioned at two sides of the first electromagnet 24 and comprises a threaded rod and a guide rod which are arranged in parallel, two ends of the threaded rod are respectively connected to the fixed seat 251, and one end of the threaded rod is provided with a first power unit;
the collector 253 is slidably connected to the first sliding rod set 252, and can scrape the metal adsorbed on the lower surface of the first electromagnet 24 from one end to the other end.
To facilitate the back and forth movement of the collector 253, the collector 253 and the first slide bar set 252 are both made of non-metallic materials from the influence of magnetic forces.
In the present embodiment, the collector 253 includes:
the first sliding seat 2531 comprises two sliding seats, which are positioned at two sides of the first electromagnet 24, respectively sleeved on the threaded rod and the guide rod of the first sliding rod group 252, and the inner sides of the sliding seats are attached to the outer side surface of the first electromagnet 24 and are higher than the bottom surface of the first electromagnet 24.
A collection box 2532 located below the first sliding seat 2531;
the middle connecting plate 2533 comprises two middle connecting plates, and is connected between the first sliding seat 2531 and the collecting box 2532 in a flaring shape.
Specifically, one end of the middle connecting plate 2533 is connected to the top angle position of the collecting box 2532, and the other end of the middle connecting plate is connected to the bottom of the rear side of the first sliding seat 2531 and is close to the outer side surface position of the first electromagnet 24. Facilitating the retraction of the needle adsorbed on the bottom surface of the first electromagnet 24.
The first scraping plate 2534 is connected to one side of the closing end of the two middle connecting plates 2533, and the top of the first scraping plate is abutted against the lower portion of the first electromagnet 24.
As a preferred embodiment, the first scraper 2534 is fastened at both ends to the outer surfaces of the two intermediate link plates 2533, as shown in FIG. 6, to prevent leakage of the needle.
When the collector 253 moves, the middle connecting plate 2533 guides the needle extending out of the edge of the first electromagnet 24 to the inner side, the first scraping plate 2534 is preferably made of elastic materials, can push the needle to move forwards and gather at one end of the lower surface of the first electromagnet 24, and after power is off, the gathered needle falls into the lower collecting box 2532. The collection box 2532 may be configured to have a lower opening to facilitate removal of the needle, or may be configured to place the buffer 254 on the first bottom support 21 below one end of the first electromagnet 24 during needle removal to collect the needle.
As a more preferable technical solution, the number of the intermediate connecting plates 2533 may be 4, and the intermediate connecting plates 2533 are symmetrically connected between the first sliding seat 2531 and the collecting box 2532 in a flaring shape, so that the collector 253 is beneficial to pushing the needle at the lower part of the first electromagnet 24 to the two ends. The embodiment shows a collector 253 of which one side is flared, since the number of broken needles is not too large.
To prevent the collector 253 from affecting the suction of the first electromagnet 24 during operation, the first power unit is connected to the control unit, and the forward running of the first power unit is controlled for T0 seconds and the reverse running of the first power unit is controlled for T0 seconds at intervals of a preset period.
During the period, the control unit controls the first power unit to act according to the feedback signal of the first metal detector 22, and collects the time Tn (n=1, 2) of each action of the first power unit;
when the single action time or the accumulated action time reaches the single cycle time T0 seconds, the control unit controls the first power unit to change or stop.
If the first action time T1 of the first power unit is more than or equal to T0, the control unit empties the timer and reckons the timer after the first power unit runs for T0 seconds;
if the first power unit operation time T1 is less than T0, the control unit accumulates the first power unit operation time until reaching T0 seconds, then the control unit empties the timing and reckons.
The rear detection zone 4 is seen to comprise in particular:
the second bottom support 41, which is arranged between the lower parts of the two side supports and is used for conveying the chopped strand mats, is positioned in the same inclined plane with the first bottom support 21, and ensures that the fiber mat always moves against the bottom support when conveyed in the detection area, and prevents deformation.
The specific structure of the second bottom support 41 will be described below with reference to fig. 11.
Similar to the first bottom support 21, the second bottom support 41 includes a second bottom plate 411 attached to the upper surfaces of the two side supports. The lower cross beam 412 is fixed at the position of the second bottom support 41 near the bottom end of the side support, and a second height adjusting member 413 is arranged at one side of the blanking portion 5 facing the rear detection area 4 and is matched with the first height adjusting member 213 to adjust the inclination of the detection area.
A second metal detector 42 is disposed laterally above the chopped strand mat transport surface. As a safety measure, the secondary detection is carried out.
The second metal detector 42 is connected to the control unit, and when the control unit receives the signal fed back by the second metal detector 42, the control unit controls the production line to be suspended. Since the second metal detector 42 is located at the lower end of the detection zone, a worker can conveniently pick out the needle.
The oscillation detection zone 3 is described below with reference to fig. 8 to 10, and specifically includes:
the oscillator 32 is located below the plane of the first bottom support 21 and the second bottom support 41, and is perpendicular to the first bottom support 21 to perform reciprocating vibration.
The oscillator 32 is connected to the control unit, and when the control unit receives the signal fed back by the first metal detector 22, the control unit controls the oscillator 32 to operate.
The third bottom plate 31 is located on the upper surface of the oscillator, the front end is in clearance fit with the edge of the first bottom support 21, a needle falling space is reserved between the rear end and the second bottom support 41, and the width of the needle falling space is not too large, so that the fiber web cannot sag excessively when passing through the space, and the fiber web is prevented from sagging, deforming or scraping on the second bottom support 41.
Moreover, the third bottom plate 31 forms a larger angle with the horizontal plane than the first bottom support 21.
A second electromagnet 34 is arranged laterally below the needle drop space for sucking the needle dropped from the needle drop space.
In order to facilitate needle taking, a second needle retracting device 33 is further arranged above the second electromagnet 34 and is used for collecting the needles adsorbed above the second electromagnet 34. The second needle retracting device 33 can scrape the needle on the upper surface of the second electromagnet 34 to the two end positions, so that a worker can conveniently take the needle from the side support.
Referring to fig. 10, in the present embodiment, the second narrowing device 33 specifically includes:
the arc-shaped supporting plate 331 is transversely fixed on the upper portion of the second electromagnet 34, the opening faces upwards, and the width of the arc-shaped supporting plate is larger than that of the second electromagnet 34.
The second sliding rod group 332 is positioned at two sides above the arc-shaped supporting plate 331 and comprises a threaded rod and a guide rod which are arranged in parallel, two ends of the threaded rod are respectively connected to the inner side of the side support, and one end of the threaded rod is provided with a second power unit;
the second sliding seat 333 comprises two sliding seats which are respectively sleeved on the threaded rod and the guide rod of the second sliding rod group 332;
the second scraping plate 334 has two upper sides respectively connected with the second sliding seat 333, and the lower part abuts against the inner side of the arc-shaped supporting plate 331.
Thus, by the back and forth movement of the second scraper 334, the needle on the second electromagnet 34 can be scraped to the two end positions which are convenient for the worker to take. Moreover, due to the arrangement of the arc-shaped carrier plate 331, the second narrowing device 33 does not need to be suspended from the first metal detector 22 feedback signal as the first narrowing device 25 does. All the metal objects falling from the needle falling space are sucked into the arc-shaped supporting plate 331 on the second electromagnet 34.
In order to improve the overall strength of the detection area, the two sides of the oscillation detection area 3 are provided with side connecting plates 7, a first bottom support 21 and a second bottom support 41 are connected, the oscillator 32 is fixed on the side connecting plates 7, and the lower part of the oscillator is provided with a support to reduce the stress of the side support.
The intelligent monitoring system firstly acquires the information of broken needles in the fiber web through the first metal detector 22, and then based on the characteristics that the chopped strand mat is soft in texture, and cannot be transported to a winding station in a floating manner and must be transported against a bottom support, the needles positioned at the lower part of the chopped strand mat cannot be taken out from the upper part. And then, the upper and lower two-stage needle picking structures are specially designed to take out all the needles on the upper surface or the lower surface of the chopped strand mats, and the normal winding of the chopped strand mats is not affected. The needle picking device is a core invention point of the application, and can really and completely realize the needle picking effect only by simultaneously providing an upper-lower two-stage needle picking structure.
Moreover, in the system, the third bottom plate 31 above the oscillator 32 is in clearance fit with the edge of the first bottom support 21, and the oscillator 32 acts perpendicular to the first bottom support 21, so that the third bottom plate 31 can be always aligned with the edge of the first support in the movement process, and the needle can not leak from the gap between the third bottom plate 31 and the first support. Because the third bottom plate 31 is greater than the first bottom support 21 and the horizontal plane, the needles hung on the lower surface of the fiber net fall on the third bottom plate 31 under the vibration action when passing through the vibration detection area 3, and only the upper half part of the third bottom plate 31 can jack up to contact with the fiber net under the action of the vibrator 32, and the lower half part is inclined downwards and far away from the fiber net and cannot contact with the fiber net, so that the needles falling on the third bottom plate 31 can not scrape the bottom of the fiber net any more, but slide down to the needle falling space along the third bottom plate 31 and are sucked on the second electromagnet 34.
Meanwhile, the system is also provided with a rear detection area 4 for secondary detection to prevent the needle which is difficult to take out from entering the winding station, and the probability of occurrence of the needle is extremely low, so that the cost performance of the needle taking equipment is increased, and a mode of manual picking by stopping the thread can be adopted.
