Description

Technical Field

[0001] This utility model relates to the field of material sorting equipment technology, and in particular to a cloth sorting machine. Background Technology

[0002] In the packaging process of the sweeper, a specific number of rags need to be stacked and packed into boxes. Currently, this rag counting and stacking operation mainly relies on manual labor. However, with manual operation, operators are prone to missing or repeating counts due to visual fatigue or distraction during continuous counting, resulting in rag quantities that do not meet actual requirements and making it difficult to guarantee consistent product quality. Secondly, the low efficiency of manual counting has become a bottleneck restricting the speed of the entire packaging process. In addition, assigning dedicated personnel to this repetitive, low-value-added work also results in a waste of human resources.

[0003] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a cloth sorting machine that can automatically stack cloths of a preset number of layers, thereby improving packaging efficiency and quality and reducing costs.

[0005] The purpose of this utility model is achieved through the following technical solution: a cloth sorting machine, comprising:

[0006] The hopper mechanism includes a storage component for storing a number of cloths to be sorted.

[0007] The palletizing mechanism is adapted to grab a single cloth from the hopper mechanism and stack the cloths one by one to the palletizing station according to a preset number of palletizing layers.

[0008] The transfer mechanism is adapted to transfer the entire stack of cloths to the unloading station when the number of layers of cloths on the stacking station reaches a preset number.

[0009] The storage component is a rod arranged in a vertical direction. A hole is opened in the middle of the cloth. Several cloths are suitable for being stacked and sleeved on the outside of the storage component through the hole in the middle. A flange for supporting the cloth is provided on the outer periphery of the storage component near the bottom.

[0010] Furthermore, the hopper mechanism includes:

[0011] A lifting component is located below the cloth in the storage component and is used to lift the cloth.

[0012] The first lifting module is connected to the lifting member in a transmission manner to drive it to move up and down in the vertical direction;

[0013] The lifting component responds to the lifting of the first lifting module, placing the topmost cloth in the loading position for the palletizing mechanism to pick up.

[0014] Furthermore, the lifting member is a plate, which includes a lifting surface for lifting the rag, and the lifting surface has a clearance portion extending downward in the vertical direction, and the storage member passes through the clearance portion;

[0015] The lifting member is adapted to move to a first position or a second position under the drive of the first lifting module. When in the first position, the lifting surface is not higher than the bearing surface of the flange. When in the second position, the lifting surface is not lower than the top of the storage member.

[0016] Furthermore, the hopper mechanism includes a feeding station for the palletizing mechanism to grab the cloth, the hopper mechanism is adapted to feed the cloth to the feeding station, and the palletizing mechanism is adapted to move back and forth between the feeding station and the palletizing station;

[0017] The transfer mechanism is disposed on the palletizing mechanism. When the palletizing mechanism moves from the loading station to the palletizing station, it is adapted to drive the transfer mechanism to move from the palletizing station to the unloading station.

[0018] Furthermore, the palletizing mechanism includes:

[0019] Transfer module;

[0020] The palletizing gripper is connected to the transfer module via a transmission and is used to pick up and place rags;

[0021] The palletizing gripper is adapted to move to the loading station or the palletizing station under the drive of the transfer module.

[0022] Furthermore, the transfer module is a linear module arranged along a first horizontal direction, and the loading station, the stacking station, and the unloading station are arranged sequentially along the first horizontal direction.

[0023] Furthermore, the transfer mechanism includes:

[0024] The second lifting module is connected to the palletizing gripper via a connector at the output end of the transfer module.

[0025] The push plate is connected to the second lifting module for transmission, so as to switch to the rising position or the falling position under the drive of the second lifting module;

[0026] When the pusher plate is in the descending position, it pushes the entire stack of cloths at the palletizing station to the unloading station in response to the palletizing gripper moving from the loading station to the palletizing station; when the pusher plate is in the ascending position, it avoids the cloths at the palletizing station in response to the palletizing gripper moving from the loading station to the palletizing station.

[0027] Furthermore, at least one palletizing gripper is arranged side by side along a second horizontal direction perpendicular to the first horizontal direction, and the loading station, the palletizing station, the unloading station, and the transfer mechanism are all corresponding to the palletizing grippers one by one.

[0028] Furthermore, the cloth sorting machine includes:

[0029] The housing, the hopper mechanism, the palletizing mechanism and the transfer mechanism are all disposed inside the housing;

[0030] A palletizing station is disposed inside the machine housing and extends partially out of the machine housing. The palletizing station is provided with a palletizing station and a material unloading station. The palletizing station is located inside the machine housing, and the material unloading station is located outside the machine housing.

[0031] Furthermore, the palletizing platform is provided with a blocking structure to keep the cloths in the palletized state.

[0032] Compared with existing technologies, this utility model has the following advantages: Through the automated collaborative operation of the hopper mechanism, palletizing mechanism, and transfer mechanism, this utility model can replace manual labor in automatically stacking cloths according to a preset number of stacking layers, and then transfer the stacked cloths to the unloading station. During the packaging process, operators or the automated handling structure only need to remove the cloths at the unloading station and package them, achieving efficient and precise operation, reducing labor costs and labor intensity, avoiding problems such as uneven placement and counting errors that exist in manual operation, and improving packaging efficiency and quality. The hopper mechanism adopts a rod-shaped storage component, which is arranged vertically. The cloths are layered and stacked on the outside of the storage component through the central opening, achieving tight vertical stacking of the cloths, greatly improving efficiency. This design saves on the floor space of the storage unit, resulting in a compact structure. The cloths to be sorted are arranged in a fixed direction and order, preventing clutter at the storage unit and providing a foundation for the palletizing mechanism to accurately pick up individual cloths each time, ensuring the orderliness and positional certainty of the supply. Furthermore, a flange is provided on the outer periphery near the bottom of the storage unit. This flange reliably supports the entire stack of cloths. When the bottom of the storage unit is fixed to the mounting surface, the flange prevents the bottom layer of cloths from contacting the mounting surface, improving the cleanliness of the cloths on the storage unit. This gap also allows operators or automated conveying structures to easily reach under the entire stack of cloths to remove them from the storage unit in case of sorting machine malfunction or maintenance.

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0041] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0042] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0043] Please see Figure 1 and Figure 2 As shown, a rag sorting machine corresponding to a preferred embodiment of the present invention includes a hopper mechanism 100, a stacking mechanism 200, and a transfer mechanism 300. The hopper mechanism 100 stores a number of rags 400 to be sorted. The stacking mechanism 200 is adapted to grab a single rag 400 from the hopper mechanism 100 and stack the rags 400 one by one to the stacking station 720 according to a preset stacking layer number. The transfer mechanism 300 is adapted to transfer the entire stack of rags 400 to the unloading station 730 when the number of rags 400 on the stacking station 720 reaches the preset layer number.

[0044] This utility model, through the automated collaborative operation of the hopper mechanism 100, the palletizing mechanism 200, and the transfer mechanism 300, can replace manual labor to automatically stack the cleaning cloths 400 according to the preset number of stacking layers, and then transfer the stacked cleaning cloths 400 to the unloading station 730. During the packaging process, the operator or the automatic handling structure only needs to remove the cleaning cloths 400 at the unloading station 730 and package them, achieving efficient and precise operation, reducing labor costs and labor intensity, avoiding problems such as uneven placement and counting errors that exist in manual operation, and improving packaging efficiency and quality.

[0045] Furthermore, referring to Figure 3As shown, the hopper mechanism 100 includes a storage unit 110 for storing the cloths 400 to be sorted. The storage unit 110 is adapted to guide the cloths 400 to be arranged in a certain pattern, such as horizontal and / or vertical, so as to facilitate the palletizing mechanism 200 to pick up the cloths according to a preset path. In this embodiment, several cloths 400 are stacked vertically, so that they are tightly packed in the vertical direction, which greatly saves the planar space of the hopper mechanism 100, making the structure compact. Moreover, the cloths 400 to be sorted are arranged in a fixed direction and order, avoiding messy accumulation at the storage unit 110. This provides a basis for the palletizing mechanism 200 to accurately pick up a single cloth 400 each time, ensuring the orderliness and positional certainty of the material supply.

[0046] Preferably, in this embodiment, the storage component 110 is a rod arranged vertically, and the rag 400 has a hole in the middle. Several rags 400 are suitable for being stacked and sleeved on the outside of the storage component 110 through the hole in the middle. Its structure is simple, low in cost, and the replenishment of rags 400 is very convenient. In addition, the storage component 110 has a flange 111 on its outer periphery near the bottom for supporting the rags 400. The storage component 110 with the above structure has a flange 111 that can reliably support the entire stack of cloths 400. When the bottom of the storage component 110 is fixed to the mounting surface, the bottom layer of cloths 400 in the storage component 110 is blocked by the flange 111, and there is a certain gap between the bottom layer of cloths 400 in the storage component 110 and the mounting surface, which avoids contact with the mounting surface and improves the cleanliness of the cloths 400 on the storage component 110. At the same time, this gap also allows operators or robotic arms and other automatic handling structures to reach under the entire stack of cloths 400 to remove the cloths 400 from the storage component 110 when the sorting machine malfunctions or is under maintenance.

[0047] Furthermore, the hopper mechanism 100 also includes a lifting member 120 and a first lifting module 130. The lifting member 120 is located below the cloth 400 of the storage member 110 and is used to lift the cloth 400. The first lifting module 130 is drively connected to the lifting member 120 to drive it to move up and down in the vertical direction. In response to the lifting of the first lifting module 130, the lifting member 120 positions the topmost cloth 400 at the loading station 710 for the palletizing mechanism 200 to pick up.

[0048] By setting up the lifting component 120 and the first lifting module 130, the material picking position of the palletizing mechanism 200 is kept constant. The palletizing mechanism 200 can grab the cloth 400 with the same posture and stroke each time, ensuring the continuity and high efficiency of the grabbing operation, and the positioning of the palletizing mechanism 200 is more accurate.

[0049] Furthermore, the lifting member 120 is a plate, which includes a lifting surface 121 for lifting the cloth 400. The lifting surface 121 has a clearance portion 122 extending vertically downwards. The storage member 110 passes through the clearance portion 122 to avoid obstructing the lifting member 120's movement. By adopting a plate-like structure with a clearance portion 122, the lifting member 120 can reliably support and lift the cloth 400, while the overall structure of the lifting member 120 is simple and easy to manufacture.

[0050] The lifting component 120 is adapted to move to a first position or a second position under the drive of the first lifting module 130. When in the first position, the lifting surface 121 is not higher than the bearing surface 112 of the flange 111 to avoid obstructing the replenishment operation of the rag 400. When in the second position, the lifting surface 121 is not lower than the top of the storage component 110 so as to lift the bottom layer of rag 400 to a position higher than the top of the storage component 110, simplifying the material transfer action of the palletizing mechanism 200. The details will be described in detail later.

[0051] The clearance portion 122 can be an opening of any shape, but in this embodiment, a circular opening is preferred, which reduces the gap between the clearance portion 122 and the storage component 110, thereby increasing the contact area between the lifting component 120 and the rag 400. Preferably, the inner wall of the clearance portion 122 has a notch 123 extending radially to the side of the lifting component 120, and the notch 123 extends to the upper and lower sides of the clearance portion 122. The notch 123 facilitates the removal of the rag 400 from the storage component 110 by operators during maintenance, and when an automated handling structure such as a robotic arm is needed to load the rag 400, the notch 123 can also avoid the robotic arm, so that the lifting component 120 does not need to descend a large distance to avoid the robotic arm, which helps to reduce the overall height and size of the hopper mechanism 100.

[0052] Admittedly, in other embodiments, when the rag 400 does not have a hole in the middle, the storage member 110 can be a cylindrical structure or other frame structure. The rag 400 is housed in the storage member 110, and its outer edge is restricted radially by the inner wall of the storage member 110. The storage member 110 has openings at both the top and bottom. The lifting member 120 can be a top rod structure, which extends into the storage member 110 through the bottom opening to lift the rag 400. The top opening of the storage member 110 allows for replenishment of the rag 400 or retrieval by the stacking mechanism 200.

[0053] Furthermore, the first lifting module 130 is a linear module arranged vertically, including a motor 131 and a lead screw 132 connected to the motor 131. A lead screw nut 133 is sleeved on the lead screw 132, and the lifting member 120 is sleeved on the lead screw 132 and fixed to the lead screw nut 133. With the above structure, the first lifting module 130 can drive the lifting member 120 to lift a preset height each time, ensuring that the topmost cloth 400 is accurately positioned at the loading station 710.

[0054] In addition, the hopper mechanism 100 also includes a mounting frame 140, which includes a base plate 141 and a top plate 142. The top plate 142 is positioned directly above the base plate 141 via a column 143. The lower end of the lead screw 132 is connected to the output end of the motor 131, and the upper end is rotatably connected to the top plate 142. The lifting member 120 is located between the base plate 141 and the top plate 142. The height of the top plate 142 is higher than the height of the loading station 710 to avoid obstructing the lifting member 120 from rising to the loading station 710. At least one guide rod 144 arranged vertically is also connected between the base plate 141 and the top plate 142. The lifting member 120 is sleeved on the guide rod 144, and a linear bearing 145 is provided between the lifting member 120 and the guide rod 144. The guide rod 144 is adapted to guide the lifting member 120 to rise and fall vertically.

[0055] Preferably, the lower end of the storage component 110 is fixedly connected to the base plate 141, meaning that all components of the hopper mechanism 100 are mounted on the mounting frame 140. The hopper mechanism 100 can function as a complete module, facilitating pre-assembly, debugging, and functional testing. Once confirmed to be functioning correctly, it is then loaded into the sorting machine as a whole. Preferably, the palletizing mechanism 200 is mounted on the top plate 142 of the mounting frame 140, connecting it to the hopper mechanism 100 as a whole, facilitating pre-assembly, debugging, and functional testing of the palletizing mechanism 200.

[0056] Furthermore, referring to Figure 4 and Figure 5 As shown, the palletizing mechanism 200 includes a transfer module 210 and a palletizing gripper 220. The transfer module 210 is disposed on the top plate 142 of the mounting frame 140. The palletizing gripper 220 is pulsatorically connected to the transfer module 210 and is adapted to move to the loading station 710 or the palletizing station 720 under the drive of the transfer module 210. In this embodiment, the palletizing gripper 220 is a needle-type suction cup, which is adapted to extend the needle to insert the cloth 400 to grasp the cloth 400, or retract the needle to separate the cloth 400 from the palletizing gripper 220. The needle-type suction cup is a known structure, and its structure will not be described in detail here.

[0057] Furthermore, the transfer mechanism 300 is disposed within the palletizing mechanism 200. When the palletizing mechanism 200 moves from the loading station 710 to the palletizing station 720, it is adapted to drive the transfer mechanism 300 from the palletizing station 720 to the unloading station 730. With this design, the transfer mechanism 300 does not require an additional moving module to travel back and forth between the palletizing station 720 and the unloading station 730, simplifying the structure of the transfer mechanism 300 and reducing costs. Admittedly, in other embodiments, the transfer mechanism 300 may also be provided with an independent moving module to achieve its travel back and forth between the palletizing station 720 and the unloading station 730.

[0058] Furthermore, since the hopper mechanism 100 is adapted to load the cloths 400 to the loading station 710 at a preset height, and when the lifting member 120 is in the second position, its lifting surface 121 is not lower than the top of the storage member 110. In addition, the palletizing gripper 220 is disposed after the transfer module 210, and its height is higher than the preset maximum palletizing height of the cloths 400 at the palletizing station 720. Therefore, in this embodiment, the transfer module 210 can be simply a straight module arranged in the horizontal direction to realize the transport and palletizing of the cloths 400.

[0059] During operation, the palletizing gripper 220 grasps the rag 400 and moves horizontally under the drive of the transfer module 210. The rag 400 is not obstructed horizontally by the storage component 110. When the palletizing gripper 220 moves above the palletizing station 720, it releases the rag 400, allowing it to fall to the palletizing station 720 without obstructing the palletizing gripper 220.

[0060] With the above structure, the palletizing mechanism 200 can pick up and palletize the rags 400 without the need for an additional lifting module, and the structure and operation of the palletizing mechanism 200 are simpler.

[0061] Preferably, the loading station 710, palletizing station 720, and unloading station 730 are arranged sequentially along a first horizontal direction. In this case, the transfer module 210 can be a linear module arranged along the first horizontal direction, instead of being composed of linear modules arranged along different horizontal directions. Since the transfer action performed by the transfer module 210 is relatively simple, requiring only the palletizing gripper 220 to move to two positions, the transfer module 210 can use a linear cylinder to reduce costs. More specifically, the transfer module 210 is a rodless cylinder, which provides smoother and more reliable movement.

[0062] Furthermore, the transfer mechanism 300 includes a second lifting module 310 and a pusher plate 320. The second lifting module 310 and the palletizing gripper 220 are connected to the output end of the transfer module 210 via a connector 211. The pusher plate 320 is drivenly connected to the second lifting module 310 to switch between an upward or downward position under the drive of the second lifting module 310. Since the second lifting module 310 only needs to move the pusher plate 320 to two positions, it also uses a linear cylinder to reduce costs.

[0063] When the pusher plate 320 is in the descending position, it pushes the stack of cloths 400 at the palletizing station 720 to the unloading station 730 in response to the palletizing gripper 220 moving from the loading station 710 to the palletizing station 720. When the pusher plate 320 is in the loading position, it avoids the cloths 400 at the palletizing station 720 in response to the palletizing gripper 220 moving from the loading station 710 to the palletizing station 720. The transfer mechanism 300 with the above structure can avoid un-palletized cloths 400 or transfer palletized cloths 400 without the need for a complex gripping structure.

[0064] Furthermore, the connector 211 is a plate extending along a second horizontal direction perpendicular to the first horizontal direction. At least one palletizing gripper 220 is arranged side-by-side along the second horizontal direction; in this embodiment, there are two, located on either side of the transfer module 210 in the second horizontal direction. In other embodiments, three, four, or more may be provided. Preferably, the number of palletizing grippers 220 on both sides of the transfer module 210 in the second horizontal direction is the same to balance the weight on the connector 211, making the transfer module 210 run more smoothly. Correspondingly, the loading station 710, palletizing station 720, unloading station 730, and transfer mechanism 300 each correspond one-to-one with the palletizing gripper 220. Each loading station 710 is equipped with a corresponding storage unit 110. The lifting unit 120 has a clearance part 122 that corresponds to the storage unit 110. The lifting unit 120 can simultaneously lift the top layer of the rag 400 of each storage unit 110 to the corresponding loading station 710.

[0065] With this design, a single transfer module 210 is suitable for driving multiple palletizing grippers 220 to simultaneously pick up and palletize materials, and the palletized cloths 400 can be pushed to the corresponding unloading station 730 by each transfer mechanism 300, so that one sorting machine can replace multiple sorting positions.

[0066] Furthermore, sensors (not shown) are installed at both the loading station 710 and the unloading station 730. The sensors can detect the presence or absence of the rag 400 at the loading station 710 and the unloading station 730, thus ensuring the coordinated operation of the hopper mechanism 100, the palletizing mechanism 200 and the transfer mechanism 300.

[0067] Furthermore, referring to Figure 1 and Figure 2 As shown, the cloth sorting machine also includes a housing 500 and a palletizing platform 600. The hopper mechanism 100, the palletizing mechanism 200, and the transfer mechanism 300 are all located inside the housing 500. The palletizing platform 600 is located inside the housing 500 and partially extends out of the housing 500. The housing 500 may be provided with a pick-up and drop-off port 510 corresponding to the storage component 110, or part of the housing 500 may be made into a door structure for operators or handling structures to load materials.

[0068] The palletizing table 600 is equipped with a palletizing station 720 and a material unloading station 730. The palletizing station 720 is located inside the machine housing 500, and the material unloading station 730 is located outside the machine housing 500, thereby effectively avoiding the safety hazards of operators retrieving materials inside the sorting machine. When the push plate 320 is in the descending position, the lower side of the push plate 320 is in contact with the table surface of the palletizing table 600, or there is a gap between the lower side of the push plate 320 and the table surface of the palletizing table 600, and this gap is less than the thickness of the cloth 400, so as to ensure that the push plate 320 can reliably push the entire stack of cloths 400.

[0069] Preferably, the palletizing table 600 is provided with a blocking structure to keep the rag 400 in a stacked state. The blocking structure includes two baffles 610, which are vertically arranged on the table surface of the palletizing table 600. The two baffles 610 are arranged opposite each other on both sides of the palletizing table 600 in the second horizontal direction, forming a barrier area between the two baffles 610 to accommodate the rag 400 and prevent the rag 400 from collapsing. The baffles 610 extend along the first horizontal direction to the palletizing station 720 and the unloading station 730 to provide guidance during the process of the transfer mechanism 300 pushing the rag 400.

[0070] The working process of this utility model cloth sorting machine is as follows: First, the lifting component 120 moves to the first position under the drive of the first lifting module 130, and the cloths 400 to be sorted are stacked on the storage component 110 by manual or automatic handling structure; then, the lifting component 120 rises to a preset height under the drive of the first lifting module 130 to lift the cloths 400 in the storage component 110, and the top layer of cloths 400 is placed at the loading station 710; then, the transfer module 210 drives the palletizing gripper 220 to move to the loading station 710, the palletizing gripper 220 grabs the cloths 400 and moves them above the palletizing station 720, and then the palletizing gripper 220 releases the cloths 400, and the cloths 400 fall to the palletizing station 720; the above actions are repeated until the palletizing station 720 is reached. The rags 400 on the 20 are at the preset stacking layer. During this process, the push plate 320 is always in the rising position to avoid affecting the stacking of the rags 400 at the stacking station 720. After the rags 400 at the stacking station 720 are at the preset stacking layer, the push plate 320 moves down to the lower position under the drive of the second lifting module 310. The push plate 320 continues to grab the rags 400 from the loading station 710 and transfer them to the stacking station 720 along with the stacking gripper 220, thus pushing the entire stack of rags 400 at the stacking station 720 to the unloading station 730. Then, the push plate 320 moves up again to the rising position under the drive of the second lifting module 310. After the rags 400 at the stacking station 720 are at the preset stacking layer again, it moves down to the lower position.
