Description

Technical Field

[0001] This application relates to the field of material distribution technology, and more specifically, to a swing arm material distribution device and a material distribution equipment. Background Technology

[0002] Soft materials (such as napkins, bath towels, and cut pieces of garment substrate) are typically stacked before being sorted. During sorting, packaging, or further processing, each piece needs to be manually removed, resulting in repetitive labor and low production efficiency. In related technologies, some production lines use adsorption sorting for soft materials, but the results are unsatisfactory. For example, in the mass production of disposable medicine packs, each medical handkerchief is folded and stacked. Conventional adsorption sorting methods struggle to adsorb and distribute each handkerchief to its respective packaging box due to the softness of the material. Insufficient suction leads to unsuccessful adsorption or the handkerchief falling during distribution, resulting in a low success rate. Excessive suction, on the other hand, causes wrinkles, affecting aesthetics and failing to meet production standards. Summary of the Invention

[0003] The purpose of this application is to provide a swing arm material feeding device and a material distribution device to solve the material distribution problem, ensure that the distributed material meets the production qualification standards, and improve the aesthetics.

[0004] To achieve the above objectives, in a first aspect, the present invention provides a swing arm feeding device, which includes a drive mechanism, a first swing arm mechanism, a second swing arm mechanism, and a frame, wherein:

[0005] The drive mechanism, the first swing arm mechanism, and the second swing arm mechanism are all mounted on the frame.

[0006] Both the first swing arm mechanism and the second swing arm mechanism are connected to the drive mechanism in a transmission manner;

[0007] The first swing arm mechanism includes an adsorption arm located at the drive end, and the second swing arm mechanism includes a material-pulling arm located at the drive end. The material-pulling arm moves alternately with the adsorption arm in a cycle, and the material-pulling arm can pass under the adsorption arm in each alternation cycle.

[0008] In an optional embodiment, the drive mechanism provides a forward drive and a reverse drive in each of the alternating cycles; the adsorption arm moves to fit the workpiece under the forward drive and moves in the reverse under the reverse drive.

[0009] In an optional embodiment, the feeding arm can pass under the adsorption arm under the reverse drive.

[0010] In an optional embodiment, the frame includes a first fixed plate, and the first swing arm mechanism further includes a first transmission component. The first transmission component is disposed on the first fixed plate, and the input end of the first transmission component is throttlely connected to the drive mechanism, and the output end of the first transmission component is slidably connected to the first fixed plate.

[0011] In an optional embodiment, the frame includes a second fixed plate, and the second swing arm mechanism further includes a second transmission component. The second transmission component is disposed on the second fixed plate, and the input end of the second transmission component is throttlely connected to the drive mechanism, and the output end of the second transmission component is slidably connected to the second fixed plate.

[0012] In an optional embodiment, the second fixing plate is provided with a groove, the shape of which is adapted to the moving path of the feeding arm.

[0013] In an optional embodiment, the second swing arm mechanism further includes an elastic element and a toggle block. The elastic element is disposed on the second fixed plate and acts on the toggle block. The toggle block is disposed in the slide groove and divides the slide groove into a first sub-slide and a second sub-slide. The slide groove further includes a third sub-slide, which connects the first sub-slide and the second sub-slide respectively.

[0014] In an optional embodiment, the swing arm feeding device further includes a switching mechanism. The frame includes a third fixed plate. The switching mechanism includes a control component, a guide structure, and a shifting module disposed on the third fixed plate. The control component acts on the guide structure, causing the guide structure to have a first guide channel and a second guide channel. The shifting module is linked with the feeding arm and moves along the first guide channel or the second guide channel during the linkage process.

[0015] In an optional embodiment, the shifting module is provided with a linkage groove adapted to the feeding arm, and the extension direction of the linkage groove is perpendicular to the axial direction of the feeding arm.

[0016] Secondly, the present invention provides a material sorting device, which includes a feeding device, a conveying device, and a swing arm material sorting device as described in the foregoing embodiments. The feeding device provides a plurality of material picking positions, which are close to the feeding end of the swing arm material sorting device. The conveying device provides a plurality of material discharging positions, which are close to the discharging end of the swing arm material sorting device.

[0017] Compared to existing technologies, the beneficial effects of this application are:

[0018] First, this application uses a drive mechanism to connect with the first swing arm mechanism and the second swing arm mechanism. On the one hand, the drive mechanism simultaneously drives the first swing arm mechanism and the second swing arm mechanism to move, which is efficient and low-cost. On the other hand, it realizes the cyclical alternation of the adsorption arm and the material feeding arm, so as to separate the stacked materials into individual workpieces. This not only improves the level of automation of material distribution, but also improves the success rate of material distribution.

[0019] Secondly, this application utilizes a design where the feeding arm can pass under the adsorption arm in each cycle. After the adsorption arm adsorbs the workpiece, the workpiece is fed from below, which improves the workpiece distribution level, reduces wrinkles caused by distribution, and ensures that the product meets production standards.

[0043] Example 1

[0044] Please see Figure 2 Multiple workpieces (i.e., the soft material mentioned in the background art above, hereinafter referred to as workpieces) are stacked vertically, and each workpiece is in a folded state, and can be configured as follows: the workpiece includes a first part 11 and a second part 12, and the first part 11 and the second part 12 are at least partially connected.

[0045] For ease of description and understanding, this application embodiment selects a medical handkerchief 10 as the workpiece. Specifically, the medical handkerchief 10 is rectangular, and the medical handkerchief 10 is folded in half along the center line 13, that is, the first part 11 and the second part 12 of the medical handkerchief 10 are connected at the center line 13.

[0046] Please see Figure 1 This application provides a swing arm feeding device, which includes a frame 500, a drive mechanism 100, a first swing arm mechanism 200 and a second swing arm mechanism 300. The drive mechanism 100, the first swing arm mechanism 200 and the second swing arm mechanism 300 are all mounted on the frame 500.

[0047] First, the frame 500 includes at least a first fixing plate 510, a second fixing plate 520, a third fixing plate 530, and a fourth fixing plate 540, and can be configured as follows: the first fixing plate 510 and the second fixing plate 520 are parallel to each other, the third fixing plate 530 and the fourth fixing plate 540 are parallel to each other, and the third fixing plate 530 is perpendicularly connected to the first fixing plate 510 and the second fixing plate 520 respectively, and the fourth fixing plate 540 is perpendicularly connected to the first fixing plate 510 and the second fixing plate 520 respectively. That is, the first fixing plate 510, the second fixing plate 520, the third fixing plate 530 and the fourth fixing plate 540 enclose a receiving cavity, and the two ends of the receiving cavity are respectively provided with a first opening and a second opening.

[0048] In this embodiment, the first fixing plate 510 is located on the right side, the second fixing plate 520 is located on the left side, the third fixing plate 530 is located on the lower side, the fourth fixing plate 540 is located on the upper side, the first opening is located on the front side, and the second opening is located on the rear side.

[0049] Please refer to further information. Figure 3 The first fixed plate 510 is provided with a first slide rail 511 and a second slide rail 512. The first slide rail 511 and the second slide rail 512 are arranged at intervals in the vertical direction, and the first slide rail 511 is closer to the fourth fixed plate 540 relative to the second slide rail 512, that is, the first slide rail 511 is located above the second slide rail 512.

[0050] Please see Figure 4 The second fixed plate 520 is provided with a sliding groove 521, the shape of which is adapted to the moving path of the feeding arm 310 described later.

[0051] Please see Figure 6 and Figure 7The third fixing plate 530 is provided with a first guide channel 421 and a second guide channel 422, and the first guide channel 421 and the second guide channel 422 intersect and are connected. In this embodiment, the first guide channel 421 and the second guide channel 422 are set in a zigzag or herringbone shape, and the herringbone shape is used as an example for illustration.

[0052] Please continue reading. Figure 1 In some other embodiments, the first fixing plate 510, the second fixing plate 520, the third fixing plate 530 and the fourth fixing plate 540 are independent mounting plates to fix the various components described below.

[0053] Furthermore, to improve the dustproof and safety performance of this embodiment, the frame 500 also includes a fifth fixing plate and a sixth fixing plate. The fifth fixing plate and the sixth fixing plate are parallel to each other, and the fifth fixing plate covers the first opening and the sixth fixing plate covers the second opening, so that the first fixing plate 510, the second fixing plate 520, the third fixing plate 530, the fourth fixing plate 540, the fifth fixing plate (not shown in the figure), and the sixth fixing plate (not shown in the figure) form a sealed box.

[0054] Secondly, the drive mechanism 100 provides forward and reverse driving actions in each alternating cycle. In this embodiment, the drive mechanism 100 may include a motor 110, a driving pulley 120, a driven pulley 130, a timing belt 140, and an output shaft 150.

[0055] The motor 110 is adapted to rotate forward or reverse, thereby providing forward and reverse driving forces in each alternating cycle. In this embodiment, the motor 110 is mounted on the side of the fourth fixing plate 540 away from the third fixing plate 530, that is, the motor 110 is placed on the fourth fixing plate 540, which provides support to ensure that the motor 110 can be placed stably. Moreover, the motor 110 is located outside the receiving cavity, which facilitates the connection between the motor 110 and the external power supply through wires, avoiding the placement of wires inside the receiving cavity and reducing the interference of wires on the operation of this embodiment.

[0056] In addition, the motor 110 is provided with an output terminal, from which torque is output.

[0057] The drive wheel 120 is fixedly connected to the output end of the motor 110 and is driven by the motor 110 to rotate forward or in reverse.

[0058] Driven wheel 130 and driving wheel 120 are connected by a synchronous belt 140, that is, driven wheel 130, driving wheel 120 and output end rotate synchronously, and synchronous rotation includes aspects such as direction of rotation and speed.

[0059] The synchronous belt 140 passes through the fourth fixed plate 540, that is, the synchronous belt 140 passes from outside the receiving cavity into the receiving cavity.

[0060] The output shaft 150 is installed between the first fixed plate 510 and the second fixed plate 520, and the output shaft 150 is located in the receiving cavity. The driven wheel 130 is installed at the left end of the output shaft 150.

[0061] Furthermore, in this embodiment of the application, a planetary reducer 160 is installed on the motor 110 to reduce the speed of the motor 110, thereby ensuring the stable operation of the output shaft 150 and subsequent components and improving operational reliability.

[0062] Furthermore, please refer to Figure 3 The first swing arm mechanism 200 is connected to the drive mechanism 100 in a transmission manner. The first swing arm mechanism 200 includes a first transmission component 220 and an adsorption arm 210.

[0063] The first transmission component 220 is disposed on the first fixed plate 510, and the input end of the first transmission component 220 is connected to the drive mechanism 100, and the output end of the first transmission component 220 is slidably connected to the first fixed plate 510.

[0064] In this embodiment, the first transmission component 220 may include a first gear 221, a second gear 222, a third gear 223, a first connecting rod 224, and a first bushing 225 connected in sequence.

[0065] The first gear 221 is installed at the right end of the output shaft 150 and serves as the input end of the first transmission assembly 220. Since the driven wheel 130 is installed at the left end of the output shaft 150, the left and right ends of the output shaft 150 are in a balanced state, thus avoiding the problem of the output shaft 150 tilting left and right due to uneven gravity during operation.

[0066] The second gear 222 meshes with the first gear 221, and the third gear 223 meshes with the second gear 222. Considering that the first swing arm mechanism 200 and the second swing arm mechanism 300 in this embodiment have different ranges and modes of motion, and are driven by the same motor 110, it is necessary to configure the three gears. Specifically, to ensure that the first swing arm mechanism 200 and the second swing arm mechanism 300 can cooperate under the positive and negative driving forces of the motor 110 without interfering with each other. Here, it is preferable to set the rotational speed of the first gear 221 and the second gear 222 to be equal to that of the motor 110, and the number of teeth of the first gear 221 and the second gear 222 to be equal. The rotational speed of the second gear 222 is defined as n1, and the number of teeth of the second gear 222 is defined as Z1. The rotational speed of the third gear 223 is defined as n2, and the number of teeth of the third gear 223 is defined as Z2. According to n1 / n2=Z2 / Z1, the number of teeth of the third gear 223 should be increased proportionally. Here, it is preferable to set Z2 / Z1=2.

[0067] In some other embodiments, the gear ratio of the first gear 221, the second gear 222, and the third gear 223 can be adaptively adjusted according to actual operating conditions.

[0068] One end of the first connecting rod 224 is connected to the third gear 223 via a flat key, which is located on the rotating shaft of the third gear 223.

[0069] The first bushing 225 is connected to the first connecting rod 224, and the first bushing 225 is slidably connected to the first fixed plate 510 and serves as the output end of the first transmission assembly 220. Specifically, the first bushing 225 slides within the first slide rail 511.

[0070] In this embodiment, the first gear 221, the second gear 222, and the third gear 223 are respectively mounted on the first fixed plate 510 via three bearings 226. The three bearings 226 are arranged to correspond to the mounting configuration of the three gears, satisfying the rotational mounting requirements of the three gears. Simultaneously, the rotation axes of the first gear 221, the second gear 222, and the third gear 223 are all perpendicular to the first fixed plate 510, and the axial direction of the first bushing 225 is also perpendicular to the first fixed plate 510. Thus, the first transmission assembly 220 achieves the linkage between the first swing arm mechanism 200, the second swing arm mechanism 300, and the motor 110 through gear transmission.

[0071] Understandably, the first swing arm mechanism 200 and the second swing arm mechanism 300 can also be driven separately by two motors 110 or two sets of power sources, but their coordination efficiency must be ensured. For example, Figure 3In the specific structure shown, when two motors 110 are driven separately, the parameters and operating conditions of the two motors 110 are consistent. Simultaneously, one motor 110 drives 130 to rotate, while the other motor 110 drives the second gear 222 to rotate. The first gear 221 is removed, while the remaining settings remain unchanged. This also achieves the linkage control between the first swing arm mechanism 200 and the second swing arm mechanism 300. However, it is clear that the linkage between the first swing arm mechanism 200 and the second swing arm mechanism 300, driven synchronously by a single motor 110, provides better operational stability.

[0072] Furthermore, the adsorption arm 210 is located at the driving end or output end of the entire first transmission assembly 220, and the adsorption arm 210 is rotatably connected to the first bushing 225. Under the forward driving action, the adsorption arm 210 moves to fit the workpiece, and under the reverse driving action, it moves in the opposite direction.

[0073] Thus, in the first swing arm mechanism 200 provided in this application embodiment, the third gear 223, the first connecting rod 224, the first bushing 225 connected in sequence and the adsorption arm 210 slidably connected to the first fixed plate 510 form a structural component that is similar to a crank-slider structure, and the swing of the adsorption arm 210 can be realized by the forward and reverse rotation of the third gear 223.

[0074] Based on this, Figure 3 The first slide rail 511 and the second slide rail 512 shown in the diagram, which slide in conjunction with the adsorption arm 210, also have a certain design background. Specifically, assuming that the adsorption arm 210 is only connected to the first bushing 225, it can also swing under the drive of the motor 110, but due to the lack of restriction and constraint, its swing trajectory is not fixed and its working stability is poor. Therefore, the working stability of the adsorption arm 210 is improved by sliding connection with the first slide rail 511 and the second slide rail 512.

[0075] Please refer to further information. Figure 3 The first slide rail 511 is designed to be arc-shaped, with its curvature center located at the rotation center of the first connecting rod 224. The second slide rail 512 can be the same arc shape as the first slide rail 511 or a straight shape, etc. Adjusting the shape of the second slide rail 512 can finely adjust the swing path of the adsorption arm 210, and can also further improve the working stability of the adsorption arm 210.

[0076] Obviously, even without the second slide 512, the adsorption arm 210 can still work under the guidance of the first slide 511, but its stability is poor.

[0077] In this embodiment, the first slide rail 511 and the second slide rail 512 are set to be arc-shaped, and the arc of the second slide rail 512 faces the second opening. The included angle of rotation of the second slide rail 512 is defined as ∠α.

[0078] Compared to other shapes of the second slide rail 512, the arc-shaped structure allows the adsorption arm 210 mentioned later to have a horizontal displacement vector after adsorbing the first part 11 of the medical towel 10, ensuring that the adsorption arm 210 only pulls the first part 11 of the medical towel 10, and does not simultaneously pick up the first part 11 and the second part 12, thereby improving the neatness and aesthetics of the medical towel 10. In addition, the arc-shaped structure can ensure the success rate of adsorption and material removal.

[0079] Please refer to it again. Figure 3 The adsorption arm 210 includes a first arm 211, a second arm 212, and a second bushing 213. The first arm 211 is connected to the first bushing 225 and extends vertically. The second arm 212 is fixedly connected to the first arm 211 and extends in a first direction perpendicular to the first fixing plate 510 and is provided with multiple adsorption holes. The multiple adsorption holes are spaced apart and face the medical square towel 10, that is, the second arm 212 and the first arm 211 form an L-shaped structure. The second bushing 213 is disposed on the first arm 211 and is slidably connected to the second slide rail 512, so that the first arm 211 swings along the second slide rail 512, thereby fixing the movement shape of the first arm 211 and the second arm 212.

[0080] Specifically, the adsorption pores are achieved through the principle of vacuum adsorption, that is, the adsorption pores are connected to an external vacuum device.

[0081] Understandably, when the motor 110 rotates forward, the first transmission component 220 is driven by the forward drive of the motor 110, and drives the first arm 211 to slide downward along the first slide rail 511 and the second slide rail 512, so that the second arm 212 swings downward along the preset trajectory to the lowest position and absorbs the medical towel 10.

[0082] When the motor 110 reverses, the first transmission component 220 is driven by the reverse drive of the motor 110, and drives the first arm 211 to slide upward along the first slide rail 511 and the second slide rail 512, so that the second arm 212 swings upward to the highest position along the preset trajectory, the medical towel 10 opens at a preset angle, and the second arm 212 releases the adsorption under certain conditions.

[0083] Finally, please refer to the following: Figure 1 , Figure 4 and Figure 5The second swing arm mechanism 300 is connected to the drive mechanism 100 in a transmission manner. In this embodiment, the second swing arm mechanism 300 may be configured to include a second transmission component 320, a toggle block 340, an elastic element 330, and a material toggle arm 310.

[0084] The second transmission component 320 is disposed on the second fixed plate 520. Specifically, the second transmission component 320 is located on the side of the second fixed plate 520 away from the first fixed plate 510, that is, the second transmission component 320 is located outside the receiving cavity, and the input end of the second transmission component 320 is connected to the drive mechanism 100, and the output end of the second transmission component 320 is slidably connected to the second fixed plate 520.

[0085] In this embodiment, the second transmission assembly 320 may include a second connecting rod 321 and a third bushing 322 connected in sequence.

[0086] The second connecting rod 321 is installed at the left end of the output shaft 150 and serves as the input end of the second transmission assembly 320. The second connecting rod 321 is provided with a through groove 3211. The through direction of the through groove 3211 is perpendicular to the second fixed plate 520, and the extension direction of the through groove 3211 is along the axial direction of the second connecting rod 321. In this embodiment, the included angle of rotation of the second connecting rod 321 can be set as ∠β, and Z2 / Z1=2, ∠β=2∠α.

[0087] The third bushing 322 passes through the through groove 3211, and one end of the third bushing 322 is connected to the feeding arm 310 mentioned later, while the other end is slidably connected to the slide groove 521. Due to the restriction of the third bushing 322 and the feeding arm 310, the second connecting rod 321 can only swing within a preset angle (i.e., ∠β).

[0088] The actuating block 340 rotates relative to the second fixed plate 520, and the rotation axis of the actuating block 340 is perpendicular to the second fixed plate 520. The actuating block 340 is disposed in the slide groove 521 and divides the slide groove 521 into a first sub-slide 5211 and a second sub-slide 5212. The slide groove 521 also includes a third sub-slide 5213, which is connected to the first sub-slide 5211 and the second sub-slide 5212 respectively.

[0089] The elastic element 330 is disposed on the second fixed plate 520 and acts on the actuating block 340. In this embodiment, the elastic element 330 can be set as a tension spring. When the actuating block 340 is pushed upward to cut off the second sub-slide 5212, the first sub-slide 5211 can pass smoothly. At this time, the tension spring deforms. When the actuating block 340 is not subjected to force, the tension spring returns to its original deformation, so that the actuating block 340 is pushed downward to cut off the first sub-slide 5211. At this time, the second sub-slide 5212 can pass smoothly.

[0090] In some other embodiments, the elastic element 330 may be configured as a coil spring, torsion spring, or other alternative.

[0091] The material-pulling arm 310 is located at the drive end and is connected to the third bushing 322. The material-pulling arm 310 is moved along the moving path under the drive of the motor 110.

[0092] Specifically, the feeding arm 310 includes a third arm 311 and a fourth arm 312. The third arm 311 is connected to the third bushing 322 and extends in a vertical direction. The fourth arm 312 is fixedly connected to the third arm 311 and extends in a second direction parallel to the first direction. That is, the fourth arm 312 and the third arm 311 also form another L-shaped structure. The two L-shaped structures are arranged facing each other, and the fourth arm 312 and the second arm 212 are always misaligned.

[0093] In order to achieve the cyclical alternation of the adsorption arm 210 and the feeding arm 310, and to ensure that the feeding arm 310 can pass under the adsorption arm 210 in each alternation cycle, that is, the feeding arm 310 can pass under the adsorption arm 210 under the reverse driving action, the embodiments of this application can be set so that the feeding arm 310 and the adsorption arm 210 can be located above or below each other during the alternation process, thereby ensuring that the travel path does not interfere with each other.

[0094] In this embodiment, the moving path of the feeding arm 310 essentially includes a first stroke and a second stroke. The second stroke is located above the first stroke. When the feeding arm 310 moves within the first stroke, the feeding arm 310... Figure 4 The material feeding arm 310 moves horizontally in the third direction along the middle; when the material feeding arm 310 moves within the second stroke, the material feeding arm 310 is in... Figure 4 It moves upwards to avoid the adsorption arm 210, and then downwards to the starting point of the first stroke.

[0095] Understandably, the first and second strokes here correspond to the forward and reverse driving forces of the motor 110. When the motor 110 rotates forward or reverse, the feeding arm 310 moves along the first or second stroke. Simultaneously, the adsorption arm 210 also needs a corresponding forward or reverse stroke to cooperate with the feeding arm 310 in adsorption and feeding operations.

[0096] Furthermore, since the shape of the chute 521 is adapted to the moving path of the feeding arm 310, the design of the chute 521 can ensure that the feeding arm 310 achieves cyclic movement along the moving path. The shape of the chute 521 includes, but is not limited to, shapes with closed contours such as triangles and quadrilaterals. In this embodiment, a triangle is used as an example. The triangle includes a first side, a second side, and a third side connected end to end. The first side extends along the third direction. The second side and the third side are both located above the first side, and the connection point of the second side and the third side serves as a clearance point between the feeding arm 310 and the adsorption arm 210.

[0097] The actuating block 340 is disposed in the slide groove 521, and the actuating block 340 cooperates with the first side to form a first sub-slide 5211, the actuating block 340 cooperates with the second side to form a second sub-slide 5212, and the actuating block 340 cooperates with the third side to form a third sub-slide 5213; the third sub-slide 5213 is located between the first sub-slide 5211 and the second sub-slide 5212, and the connection between the third sub-slide 5213 and the second sub-slide 5212 serves as a clearance position between the material feeding arm 310 and the adsorption arm 210.

[0098] When the motor 110 rotates forward, the third bushing 322 slides along the third direction in the first sub-slide rail 5211. The actuating block 340 is pushed upward by the third bushing 322. At this time, the feeding arm 310 moves within the first stroke. When the third bushing 322 slides out of the first sub-slide rail 5211, the motor 110 reverses. The actuating block 340 is pushed downward and reset by the elastic force of the elastic element 330. The third bushing 322 can continue to slide along the third direction in the opposite direction in the second sub-slide rail 5212 and the third sub-slide rail 5213. At this time, the feeding arm 310 moves within the second stroke.

[0099] The connection between the first sub-slide 5211 and the third sub-slide 5213 is the starting point of the first journey and the ending point of the second journey. The connection between the first sub-slide 5211 and the second sub-slide 5212 is the ending point of the first journey and the starting point of the second journey.

[0100] It is understandable that when the third bushing 322 slides on the first sub-slide rail 5211, the material feeding arm 310 is located below the adsorption arm 210, and when the third bushing 322 slides to the connection between the second sub-slide rail 5212 and the third sub-slide rail 5213, the material feeding arm 310 is located above the adsorption arm 210.

[0101] In this embodiment, the combined action of the slide groove 521, the agitator block 340, and the elastic element 330 not only realizes the cyclic movement of the feeding arm 310, but also ensures the reliability of the alternating movement of the feeding arm 310 and the adsorption arm 210.

[0102] In this embodiment, the folding direction of the medical towel 10 can be set to face away from the swing arm feeding device, and the center line 13 is located behind the adsorption arm 210. Therefore, when the adsorption arm 210 adsorbs the first part 11 and rises to a preset height, the first part 11 and the second part 12 are set at an angle. The feeding arm 310 moves alternately to the angle position relative to the adsorption arm 210, and the medical towel 10 is moved by the angle, so that the adjacent medical towels 10 are separated.

[0103] Since the chute 521 is triangular, the third bushing 322 moves along the triangular outline of the chute 521 to realize the alternating movement of the feeding arm 310 and the adsorption arm 210.

[0104] In some other embodiments, the chute 521 is square, and the third bushing 322 moves along the square outline of the chute 521 to achieve the staggered movement of the feeding arm 310 and the adsorption arm 210.

[0105] In some other embodiments, the chute 521 is semi-circular, and the third bushing 322 moves along the semi-circular contour of the chute 521 to achieve the alternating movement of the feeding arm 310 and the adsorption arm 210.

[0106] For further information, please refer to [link / reference]. Figure 4 and Figure 5 The second swing arm mechanism 300 also includes a sliding block 350, a first linear guide rail 360 and a second linear guide rail 370. The sliding block 350 is slidably engaged with the first linear guide rail 360. The first linear guide rail 360 is parallel to the pushing direction of the feeding arm 310. That is, the first linear guide rail 360 is mounted on the second fixed plate 520 and extends in the third direction, and the second linear guide rail 370 is mounted on the sliding block 350 and extends in the vertical direction.

[0107] Specifically, when the motor 110 rotates forward and drives the second connecting rod 321 to swing along the third direction, the third bushing 322 is driven by the second connecting rod 321 to slide along the third direction in the first sub-slide rail 5211. At this time, the sliding block 350 moves relative to the first linear guide rail 360 along the third direction, and the third arm 311 does not move relative to the second linear guide rail 370.

[0108] When the motor 110 reverses and drives the second link 321 to swing in the opposite direction of the third direction, the third bushing 322 is driven by the second link 321 to slide in the second sub-slide rail 5212 in the opposite direction of the third direction. At this time, the sliding block 350 moves relative to the first linear guide rail 360 in the opposite direction of the third direction, the third arm 311 moves upward relative to the second linear guide rail 370, and the third bushing 322 is driven by the second link 321 to slide in the third sub-slide rail 5213 in the opposite direction of the third direction. At this time, the sliding block 350 continues to move relative to the first linear guide rail 360 in the opposite direction of the third direction, and the third arm 311 moves downward relative to the second linear guide rail 370.

[0109] The embodiments of this application, by setting the first linear guide rail 360 and the second linear guide rail 370, make the movement of the feeding arm 310 more stable, ensuring that the feeding arm 310 moves along the movement path and preventing the feeding arm 310 from leaving the movement path due to inertia.

[0110] Please refer to further information. Figure 6 and Figure 7 The material taking position and the material discharging position 570 of the swing arm feeding device are set in equal proportion. For example, there is one material taking position and one material discharging position 570, or there are two material taking positions and two material discharging positions 570.

[0111] Please refer to the following: Figure 8 , Figure 9 and Figure 10 Based on the specific details of the above embodiments, the operating principle of the swing arm feeding device within one alternating cycle is explained as follows:

[0112] S100. When the motor 110 rotates forward, the first transmission component 220 drives the adsorption arm 210 to swing downward to fit the medical towel 10 to be adsorbed. The second transmission component 320 is driven by the forward drive of the motor 110. The third bushing 322 slides along the first sub-slide rail 5211. The material-dispensing arm 310 moves within the first stroke. When the adsorption arm 210 swings to the lowest position, the material-dispensing arm 310 moves to the end of the first stroke, realizing the dispensing of the previous medical towel 10.

[0113] S200. When the motor 110 reverses, the first transmission component 220 drives the adsorption arm 210 to swing upward. The second transmission component 320 is driven by the reverse drive of the motor 110. The third bushing 322 slides along the second sub-slide 5212 and the third sub-slide 5213. The material-pulling arm 310 moves within the second stroke. When the adsorption arm 210 swings to the highest position, the medical square towel 10 opens at a certain angle. The material-pulling arm 310 passes the clearance position and moves to the end of the second stroke. At the same time, it can be further set that the adsorption arm 210 releases its adsorption effect at the moment the material-pulling arm 310 pulls the medical square towel 10 or after a certain period of time.

[0114] Example 2

[0115] Please refer to the following: Figure 1 and Figure 5 Based on Embodiment 1, this application provides a swing arm material feeding device, which further includes a switching mechanism 400. The switching mechanism 400 includes a control component 410, a guide structure 420, and a shifting module 430 disposed on a third fixed plate 530.

[0116] The control component 410 acts on the guide structure 420. Specifically, the control component 410 includes a first actuating cylinder 411, a second actuating cylinder 412, and related controllers and control circuits.

[0117] The guide assembly includes two zigzag or herringbone-shaped guide channels, and the guide structure 420 is formed by the control assembly 410 to form a first guide channel 421 and a second guide channel 422. The first guide channel 421 is correspondingly arranged with the first actuating cylinder 411, and the second guide channel 422 is correspondingly arranged with the second actuating cylinder 412.

[0118] When the first actuating cylinder 411 retracts and the second actuating cylinder 412 extends, the first guide channel 421 opens and the second guide channel 422 closes. Similarly, when the first actuating cylinder 411 extends and the second actuating cylinder 412 retracts, the first guide channel 421 closes and the second guide channel 422 opens.

[0119] The shifting module 430 is linked with the feeding arm 310 and moves along the first guide channel 421 or the second guide channel 422 during the linkage process. The shifting module 430 is provided with a linkage groove 4321 adapted to the feeding arm 310. The extension direction of the linkage groove 4321 is perpendicular to the axial direction of the feeding arm 310. Specifically, the extension direction of the linkage groove 4321 is perpendicular to the axial direction of the third arm 311.

[0120] Please refer to the following: Figure 6 and Figure 7 In this embodiment of the application, the feeding arm 310 can be set to move from the first station 550 or the second station 560 to the discharge station 570. The first guide channel 421 and the second guide channel 422 are arranged in a herringbone shape, and the included angle between the first guide channel 421 and the second guide channel 422 is an acute angle, which is directed toward the discharge station 570.

[0121] When the shifting module 430 moves along the first guide channel 421, the feeding arm 310 feeds material at the first station 550. When the shifting module 430 moves along the second guide channel 422, the feeding arm 310 feeds material at the second station 560. The second station 560 and the first station 550 are arranged at an axial interval along the fourth arm 312.

[0122] Please continue reading. Figure 5 The linkage between the transposition module 430 and the feeding arm 310 is implemented as follows:

[0123] The switching mechanism 400 also includes a third linear guide rail 440 and a fourth linear guide rail 450. The third linear guide rail 440 is disposed on the fourth fixed plate 540, and the extension direction of the third linear guide rail 440 is the same as the extension direction of the first guide channel 421. The fourth linear guide rail 450 is slidably connected to the third linear guide rail 440, and the extension direction of the fourth linear guide rail 450 is perpendicular to the extension direction of the third linear guide rail 440.

[0124] The switching module 430 includes a body 431, a material feeding plate 432, and a fourth bushing 433. The body 431 is slidably connected to the fourth linear guide rail 450. The material feeding plate 432 is fixedly connected to the body 431 and is provided with the aforementioned linkage groove 4321. The fourth arm 312 moves up and down within the linkage groove 4321. The fourth bushing 433 is installed on the body 431 and is slidably connected to the first guide channel 421 or the second guide channel 422. Under the action of the first guide channel 421 or the second guide channel 422, the fourth bushing 433 causes the body 431 to slide along the fourth linear guide rail 450.

[0125] Please refer to the following: Figure 6 and Figure 7 Based on the specific details of the above embodiments, the linkage operation principle of the material feeding arm 310 and the switching mechanism 400 in the swing arm feeding device is explained as follows:

[0126] S310. The material-pulling arm 310 actuates the medical square towel 10, and the movement of the material-pulling arm 310 can drive the switching mechanism 400 to move along the third linear guide rail 440;

[0127] S320. If the first guide channel 421 is opened and the second guide channel 422 is closed, the fourth bushing 433 slides in the first guide channel 421, and the feeding arm 310 moves along the first linear guide rail 360, thereby moving the medical towel 10 from the first station 550 to the discharge station 570.

[0128] S330. If the second guide channel 422 is opened and the first guide channel 421 is closed, the fourth bushing 433 slides in the second guide channel 422, the feeding arm 310 moves along the first linear guide rail 360, and the feeding plate 432 moves along the fourth linear guide rail 450, thereby moving the medical towel 10 from the second station 560 to the discharge station 570.

[0129] By setting the switching mechanism 400, the switching and material allocation between the first station 550 and the second station 560 is realized. When the material at the first station 550 is used up, the material allocation at the second station 560 continues in this embodiment. The operator can use the time difference to replenish the material at the first station 550. Similarly, when the material at the second station 560 is used up, the material allocation at the first station 550 can continue in this embodiment. The operator can use the time difference to replenish the material at the second station 560. Therefore, this embodiment can realize uninterrupted material allocation, reduce waiting time for replenishment, and save production costs.
