Description

Technical Field

[0001] This utility model relates to the field of automatic fabric dropping equipment, and in particular to a roller picking device for an automatic fabric dropping robot. Background Technology

[0002] Automated fabric dosing robots are core automation equipment in industries such as textiles, nonwovens, and automotive interiors. Their core value lies in automating the picking, placing, transferring, and conveying of fabric rolls (cloth rolls). By replacing traditional manual operations, they effectively reduce labor intensity, minimize human error, and thus improve the overall operating efficiency and product quality stability of the production line. Currently, mainstream automated fabric dosing robots generally integrate a transport vehicle, a fabric dosing device, and roller picking devices. These components work together to complete the entire process from fabric dosing to subsequent processing. Among these, the roller picking device, as a key link in the transfer of the roll, directly determines the overall operational performance of the equipment through its structural rationality and functional integrity.

[0003] In the prior art, a typical automatic fabric dropping robot roller picking device (such as the patent with announcement number CN120308728A) mainly consists of a shell, a top rod, a limiting cylinder and a conveyor belt.

[0004] However, the existing roller-taking devices described above have significant drawbacks in practical applications, making it difficult to meet the demands for efficient and stable production: 1. The lack of independent roller storage and layered limiting structure means that the temporary storage of rollers relies entirely on the conveying device, which makes it impossible to achieve orderly storage of multiple rollers. This results in the equipment having to wait frequently for external roller transfers during continuous operation, thus restricting the continuous operation capability. 2. The roller picking device lacks a stable waiting area and an orderly feeding mechanism. There is no fixed waiting space before the rollers enter the conveyor belt, and it cannot feed each roller individually. This easily leads to blockages caused by multiple rollers entering the conveyor belt simultaneously, directly affecting the smooth operation of the production line. These problems result in insufficient stability and efficiency of the roller picking process in existing automatic fabric unloading robots. Utility Model Content

[0005] To address the current issues of unorganized storage of multiple rollers and the tendency for conveyor belts to cause clogging when transporting rollers, this invention provides a roller-picking device for an automatic fabric unloading robot.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: An automatic fabric dropping robot has a roller-picking device, comprising a housing with an open front side, a vertical limiting component disposed on the rear inner side of the housing, the vertical limiting component and the rear wall of the housing forming a roller dropping channel; a transverse limiting component for placing rollers and a feeding plate forming an acute angle α with the rear wall of the housing are also disposed on the inner side wall of the housing, the rollers on the transverse limiting component can fall onto the feeding plate through the roller dropping channel; a baffle is disposed at the end of the feeding plate away from the rear wall of the housing; a material blocking component is also disposed inside the housing; the space between the material blocking component, the baffle and the feeding plate forms a roller-picking area, and the rollers on the feeding plate can enter the roller-picking area one by one through the material blocking component. The automatic fabric dropping robot uses a roller-picking device. The roller-picking device, formed by the front open shell, vertical limiting component, and rear wall, guides the rollers on the horizontal limiting component to fall onto the inclined feeding plate, avoiding roller transfer deviation and jamming. At the same time, the horizontal limiting component can realize the orderly storage of multiple rollers, eliminating the dependence on temporary storage of external conveying devices and improving continuous operation capability. Furthermore, the material blocking component, baffle, and feeding plate enclose the roller-picking area, allowing the rollers to enter the roller-picking area one by one, eliminating the blockage problem caused by multiple rollers being conveyed at the same time, and significantly improving the stability and operation efficiency of the roller-picking process.

[0007] Preferably, the material blocking assembly includes a rotating shaft and a cover plate fixedly disposed within the housing; the cover plate is positioned above the feeding plate; one end of the cover plate is fixedly connected to a vertical limiting component, and the other end of the cover plate extends above the rotating shaft; both ends of the rotating shaft are rotatably disposed on the housing below the feeding plate; a feeding wheel is mounted on the rotating shaft; the rotating shaft is connected to a drive unit; a proximity switch is installed on the inner wall of the housing in conjunction with the roller area to be picked up; the proximity switch is electrically connected to the drive unit. In this material blocking assembly, the cover plate above the feeding plate can limit the roller shaft, preventing the roller shaft from shifting or stacking during the feeding process, ensuring a stable feeding path; the rotating shaft drives the feeding wheel in conjunction with the drive unit, which can actively control the roller shaft conveying rhythm; and the proximity switch in the roller area to be picked up is electrically connected to the drive unit, which can automatically detect the status of the roller shaft in the roller area to be picked up, and trigger the feeding wheel as needed to send the roller shaft into the roller area one by one, realizing the automation and orderliness of roller picking and feeding, further reducing the risk of multi-roller blockage, and improving the accuracy and efficiency of the roller picking process.

[0008] Preferably, the distance between the cover plate and the feeding plate is equal to 1.1 to 1.3 times the outer diameter of the roller. This provides sufficient clearance for the roller to ensure smooth movement on the feeding plate and avoid jamming, while precise control of the spacing prevents the roller from tilting, misaligning, or stacking during conveying. This further ensures that the rollers enter the roller-retrieving area one by one in an orderly manner, providing precise dimensional support for the stable and efficient roller-retrieving process.

[0009] Preferably, the proximity switch is mounted on a fixed plate; the fixed plate is fixedly positioned below the area where the rollers are to be picked up. The mounting position below the area where the rollers are to be picked up allows the proximity switch to directly and accurately detect the presence or status of the rollers in the area, ensuring timely feedback of signals to the drive unit to trigger material feeding as needed, effectively avoiding feeding disorder caused by false detection, and further ensuring the orderly feeding of the rollers.

[0010] Preferably, the feeding plates include two plates, which are respectively installed on the left and right side walls inside the housing; the feeding wheels include two wheels, which are keyed to both ends of the rotating shaft; the feeding wheels are positioned between the two feeding plates. The two feeding plates, located on the left and right side walls inside the housing, can provide stable support to the roller shaft from both ends, preventing the roller shaft from tipping over or shifting during feeding; the two feeding wheels, keyed to both ends of the rotating shaft and located between the two feeding plates, can apply a feeding force to the roller shaft synchronously and symmetrically, avoiding jamming of the roller shaft due to uneven force, ensuring that the roller shaft moves smoothly along the feeding plates, and further ensuring that it enters the waiting roller area one by one in an orderly manner.

[0011] Preferably, the feeding wheel includes a wheel body; a plurality of arc grooves are evenly arranged on the outer wall of the wheel body along the circumference. The arc grooves on the outer wall of the feeding wheel can be precisely matched with the outer wall of the roller shaft, increasing the contact area between the two to prevent the roller shaft from slipping or deviating during feeding, ensuring stable feeding of the roller shaft; and the even distribution of the arc grooves along the circumference makes the feeding action regular and controllable, ensuring that only one roller shaft is moved at a time, accurately controlling the feeding rhythm, and further ensuring that the roller shafts enter the waiting roller area one by one in an orderly manner, avoiding feeding disorder.

[0012] Preferably, the drive unit includes a motor; the motor output shaft is connected to a rotating shaft; the motor is connected to a controller; both the controller and the motor are housed in a mounting slot on the outer wall of the housing; a proximity switch is electrically connected to the controller. The integration of the controller and motor into the mounting slot on the outer wall of the housing avoids occupying the internal roller conveying space, prevents interference with internal components, and facilitates later inspection and maintenance.

[0013] Preferably, the vertical limiting assembly includes two sets of vertical partitions; the two sets of vertical partitions are respectively fixedly installed on the left and right walls inside the housing; each set of vertical partitions includes several vertical plates; the several vertical plates are located in the same vertical plane, and adjacent vertical plates are spaced apart; the lower end of the lowermost vertical plate is connected to a cover plate. The two sets of vertical partitions are located on the left and right walls inside the housing, which can form vertical limiting from both sides of the roller shaft, preventing the roller shaft from shifting left or right when falling or transferring in the roller drop channel; the several vertical plates in each set are located in the same vertical plane and spaced apart, which can ensure the unobstructed flow of the roller drop channel and provide stable guidance for the roller shaft; the lowermost vertical plate is connected to the cover plate, which can also realize the smooth connection between the roller drop channel and the feeding plate, ensuring that the roller shaft falls smoothly onto the feeding plate, laying the foundation for subsequent orderly feeding.

[0014] Preferably, the lateral limiting component includes two sets of lateral support plates; the two sets of lateral support plates are respectively fixedly installed on the left and right walls inside the housing; each set of lateral support plates includes several horizontal plates; each horizontal plate end is correspondingly connected to the upper end of a vertical plate; the horizontal plates are arranged parallel to the feeding plate. The two sets of lateral support plates are respectively located on the left and right walls inside the housing, which can form a stable support from both ends of the roller shaft, preventing the roller shaft from tipping over or falling during storage; each set of horizontal plates is correspondingly connected to the upper end of the vertical plate, which can work together with the vertical limiting component to form a layered storage structure, realizing the orderly storage of multiple roller shafts and eliminating the dependence on temporary storage of external conveying devices; and the parallel arrangement of the horizontal plates and the feeding plate can ensure that the roller shaft falls smoothly from the horizontal plate through the roller drop channel to the feeding plate, reducing jamming problems caused by angular deviations, and laying a stable foundation for subsequent orderly feeding.

[0015] Preferably, a bending plate is fixedly provided at the end of each horizontal plate away from the vertical plate. The bending plate at the end of each horizontal plate away from the vertical plate can form an outer limit for the rollers stored on the horizontal plate, effectively preventing the rollers from slipping off the outer end of the horizontal plate due to slight vibration of the equipment or storage offset.

[0016] As can be seen from the above technical solutions, the advantages of this utility model include: the automatic fabric dropping robot uses a roller picking device that guides the rollers on the lateral limiting component to fall onto the inclined feeding plate through the roller dropping channel formed by the front open shell, the vertical limiting component, and the rear wall, thus avoiding roller transfer deviation and jamming; at the same time, the lateral limiting component can realize the orderly storage of multiple rollers, eliminating the dependence on temporary storage of external conveying devices and improving continuous operation capability; and the material blocking component, the baffle, and the feeding plate enclose the roller picking area, which allows the rollers to enter the roller picking area one by one, eliminating the blockage problem caused by the simultaneous conveying of multiple rollers, and significantly improving the stability and operation efficiency of the roller picking process.

Detailed Implementation

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0026] like Figure 1-4 As shown, an automatic fabric dropping robot roller-picking device includes a housing 1 with an open front side. A vertical limiting component is provided on the rear inner side of the housing 1, and the vertical limiting component and the rear wall of the housing 1 form a roller dropping channel 2. A transverse limiting component for placing rollers 3 and a feeding plate 4 forming an acute angle α with the rear wall of the housing 1 are also provided on the inner side wall of the housing 1. The rollers 3 on the transverse limiting component can fall onto the feeding plate 4 through the roller dropping channel 2. A baffle 5 is provided at the end of the feeding plate 4 away from the rear wall of the housing 1. A material blocking component is also provided inside the housing 1. The space between the material blocking component, the baffle 5 and the feeding plate 4 forms a roller-picking area 11, and the rollers 3 on the feeding plate 4 can enter the roller-picking area 11 one by one through the material blocking component. In this embodiment, the acute angle α is 85°.

[0027] The automatic fabric dropping robot uses a roller-picking device that guides the rollers 3 on the lateral limiting component to fall onto the inclined feeding plate 4 through the roller dropping channel 2 formed by the front open housing 1, the vertical limiting component, and the rear wall, thus preventing the rollers 3 from shifting, deviating, or getting stuck. At the same time, the lateral limiting component can achieve orderly storage of multiple rollers 3, eliminating the dependence on temporary storage of external conveying devices and improving continuous operation capability. Furthermore, the material blocking component, the baffle 5, and the feeding plate 4 enclose the roller-picking area 11, which allows the rollers 3 to enter the roller-picking area 11 one by one, eliminating the blockage problem caused by the simultaneous conveying of multiple rollers and significantly improving the stability and operation efficiency of the roller picking process.

[0028] In the above configuration, the vertical limiting assembly includes two sets of vertical partitions; the two sets of vertical partitions are respectively fixedly installed on the left and right walls inside the housing 1; each set of vertical partitions includes several vertical plates 14; the several vertical plates 14 are located in the same vertical plane, and adjacent vertical plates 14 are spaced apart; the lower end of the lowest vertical plate 14 is connected to a cover plate 6. The lateral limiting assembly includes two sets of lateral support plates; the two sets of lateral support plates are respectively fixedly installed on the left and right walls inside the housing 1; each set of lateral support plates includes several horizontal plates 15; each horizontal plate 15 is connected to the upper end of a vertical plate 14 at its end; the horizontal plates 15 are arranged parallel to the feeding plate 4. A bending plate 16 is fixedly installed at the end of each horizontal plate 15 away from the vertical plate 14.

[0029] Two sets of vertical partitions are respectively installed on the left and right walls inside the housing 1, which can form vertical limits from both sides of the roller 3 to prevent the roller 3 from shifting left or right when falling or transferring in the roller drop channel 2; several vertical plates 14 in each set are located on the same vertical plane and are spaced apart, which can not only ensure the unobstructed flow of the roller drop channel 2, but also provide stable guidance for the roller 3; the bottom vertical plate 14 is connected to the cover plate 6, which can also realize the smooth connection between the roller drop channel 2 and the feeding plate 4, ensuring that the roller 3 falls smoothly onto the feeding plate 4, laying the foundation for subsequent orderly feeding. Two sets of transverse support plates are respectively located on the left and right walls of the housing 1, which can form a stable support from both ends of the roller shaft 3 to prevent the roller shaft 3 from tipping over or falling during storage. Each set of transverse plates 15 is connected to the upper end of the vertical plate 14, and can work with the vertical limiting component to form a layered storage structure, realizing the orderly storage of multiple roller shafts 3 and eliminating the dependence on external conveying devices for temporary storage. Moreover, the transverse plates 15 are set parallel to the feeding plate 4, which can ensure that the roller shaft 3 falls smoothly from the transverse plate 15 through the drop roller channel 2 to the feeding plate 4, reducing jamming problems caused by angular deviations and laying a stable foundation for subsequent orderly feeding. The bent plate 16 at the end of each transverse plate 15 away from the vertical plate 14 can form an outer limit for the roller shaft 3 stored on the transverse plate 15, effectively preventing the roller shaft 3 from slipping off the outer end of the transverse plate 15 due to slight vibration of the equipment or storage offset.

[0030] In other alternative embodiments, the two vertical plates 14 at the same height are replaced by a single plate, the two ends of which are fixedly mounted on the left and right walls inside the housing 1, respectively. The horizontal plates 15 at the same height are replaced by a single plate, the two ends of which are fixedly mounted on the left and right walls inside the housing 1, respectively.

[0031] The material blocking assembly includes a rotating shaft 7 and a cover plate 6 fixedly installed inside the housing 1. The cover plate 6 is positioned above the feeding plate 4. One end of the cover plate 6 is fixedly connected to a vertical limiting component, and the other end of the cover plate 6 extends above the rotating shaft 7. Both ends of the rotating shaft 7 are rotatably mounted on the housing 1 below the feeding plate 4. A feeding wheel 8 is installed on the rotating shaft 7. The rotating shaft 7 is connected to a drive unit. A proximity switch 9 is installed on the inner wall of the housing 1 to match the area to be picked up from the roller. The proximity switch 9 is electrically connected to the drive unit. The distance between the cover plate 6 and the feeding plate 4 is equal to 1.2 times the outer diameter of the roller shaft 3. In this material blocking assembly, the cover plate 6 above the feeding plate 4 can limit the roller shaft 3, preventing the roller shaft 3 from shifting or stacking during the feeding process and ensuring the stability of the feeding path; the rotating shaft 7 drives the feeding wheel 8 in conjunction with the drive unit, which can actively control the conveying rhythm of the roller shaft 3; and the proximity switch 9 of the waiting roller area 11 is electrically connected to the drive unit, which can automatically detect the status of the roller shaft 3 in the waiting roller area 11, and trigger the feeding wheel 8 as needed to send the roller shaft 3 into the waiting roller area 11 one by one, realizing the automation and orderliness of roller feeding, further reducing the risk of multi-roller blockage, and improving the accuracy and efficiency of the roller feeding process.

[0032] The proximity switch 9 is mounted on the fixed plate 10; the fixed plate 10 is fixedly positioned below the roller-taking area 11. Two feeding plates 4 are included, each mounted on the left and right side walls of the housing 1. Two feeding wheels 8 are included, each keyed to both ends of the rotating shaft 7; the feeding wheels 8 are positioned between the two feeding plates 4. The drive unit includes a motor 12; the output shaft of the motor 12 is connected to the rotating shaft 7; the motor 12 is connected to a controller 13; both the controller 13 and the motor 12 are located in the mounting groove 101 on the outer wall of the housing 1; the proximity switch 9 is electrically connected to the controller 13. The mounting position below the roller-taking area 11 allows the proximity switch 9 to directly and accurately detect the presence or status of the rollers 3 within the area, ensuring timely feedback signals to the drive unit to trigger feeding as needed, effectively avoiding feeding disorder caused by false detection, and further ensuring the orderly feeding of the rollers. Two feeding plates 4 are respectively located on the left and right side walls inside the housing 1, providing stable support from both ends of the roller shaft 3 to prevent it from tipping over or shifting during feeding. Two feeding wheels 8 are keyed to both ends of the rotating shaft 7 and located between the two feeding plates 4, enabling them to apply feeding force to the roller shaft 3 synchronously and symmetrically, preventing the roller shaft 3 from jamming due to uneven force, ensuring that the roller shaft 3 moves smoothly along the feeding plates 4, and further ensuring that it enters the waiting roller area 11 one by one in an orderly manner. The controller 13 and the motor 12 are integrated into the mounting groove 101 on the outer wall of the housing 1, which does not occupy the conveying space of the roller shaft 3 inside the housing 1, avoids interference with internal components, and facilitates later inspection and maintenance.

[0033] like Figure 5As shown, the feeding wheel 8 includes a wheel body 801; several arc grooves 802 are evenly arranged on the outer wall of the wheel body 801 along the circumferential direction. The arc grooves 802 on the outer wall of the feeding wheel 8 wheel body 801 can be precisely matched with the outer wall of the roller shaft 3, increasing the contact area between the two to avoid the roller shaft 3 slipping and deviating during feeding, ensuring stable feeding of the roller shaft 3; and the even distribution of the arc grooves 802 along the circumference makes the feeding action regular and controllable, ensuring that only one roller shaft 3 is moved each time, accurately controlling the feeding rhythm, and further ensuring that the roller shafts 3 enter the waiting roller area 11 one by one in an orderly manner, avoiding feeding disorder.

[0034] The working principle of the automatic fabric dispensing robot's roller-picking device is as follows: First, the bearings 301 on the roller necks at both ends of the roller shaft 3 are placed on the horizontal plates 15 on the left and right inner walls of the housing 1 of the roller taking device. The bending plates 16 at the ends of the horizontal plates 15 form an outer limit on the bearings 301 to prevent the roller shaft 3 from slipping off the outer end of the horizontal plates 15 due to equipment vibration or storage offset. At the same time, the two sets of horizontal support plates and the vertical limiting components work together to achieve layered and orderly storage of multiple roller shafts 3. When it is necessary to feed material to the roller taking area 11, the roller shaft 3 on the horizontal plate 15 falls directionally along the roller falling channel 2 formed by the vertical limiting components (two sets of vertical partitions) and the rear wall of the housing 1 under the action of gravity. Since the horizontal plate 15 is set parallel to the feeding plate 4, the roller shaft 3 falls smoothly onto the feeding plate 4, which forms an acute angle with the rear wall of the housing 1. At this time, the controller 13 of the drive unit receives the detection signal from the proximity switch 9 below the roller area 11 to be picked up: if there is no roller 3 in the roller area 11 to be picked up, the controller 13 starts the motor 12, the output shaft of the motor 12 drives the rotating shaft 7 to rotate, and the feeding wheels 8 at both ends of the rotating shaft 7 rotate synchronously. The arc groove 802 of the wheel body 801 of the feeding wheel 8 is precisely matched with the roller 3 on the feeding plate 4, and the roller 3 is pushed one by one to the roller area 11 to be picked up; if the proximity switch 9 detects that there is already a roller 3 in the roller area 11 to be picked up, the controller 13 controls the motor 12 to stop running to avoid multiple rollers entering the roller area 11 to be picked up at the same time. After the subsequent roller picking operation, the above feeding process is repeated to achieve the orderly supply of roller 3.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
