Description

Technical Field

[0001] This utility model relates to the field of feeding home textile products, and in particular to a feeding unit and feeding device for home textile products. Background Technology

[0002] Currently, the production and packaging of home textile products are completed through assembly lines. After a stack of bed sheets and other home textile products are transported to the loading position, they are loaded manually. Manual loading has technical problems of high labor intensity and low efficiency.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN222555933U discloses an automatic fabric gripping and feeding device, including a laser cutter and a robot. The end flange of the robot is equipped with flexible mechanical grippers. During operation, after the laser cutter delivers the cut fabric pieces to the designated position, the vision module on the laser cutter can detect the closed-loop contour of each fabric piece and communicate with the controller of the robot to provide the gripping coordinate points of each fabric piece. The robot moves the flexible mechanical grippers directly above the fabric piece, lowers the flexible mechanical grippers, and applies 5mm of pressure when the flexible mechanical grippers contact the fabric piece. The three-axis cylinder on the flexible mechanical grippers closes the two claws, separating and gripping the fabric piece from the fabric strip. The robot then moves the fabric piece above the material box ejection position, drives the cylinder on the flexible mechanical grippers to open the two claws, and drops the fabric piece into the turnover box.

[0004] In the above technical solutions, flexible grippers are used to transfer the fabric to the turnover box. However, in the production line of home textile products, the products are stacked on the rack and need to be continuously transferred to the automated production line for clamping. After clamping, the products undergo ironing, quality inspection, or folding processes. These processes require accurate clamping and positioning of the home textile products to ensure full-width processing. However, using flexible grippers to directly grasp the products will cause wrinkles on the lower layers, causing the gripping position of the lower layers to shift, affecting continuous feeding, interrupting production, and impacting production efficiency. Utility Model Content

[0005] In order to solve the technical problem in the prior art that the flexible gripper feeding causes wrinkling and movement of the lower layer products, affecting the continuous feeding, this utility model provides a home textile product feeding unit and feeding device, which can greatly avoid wrinkling of the feeding clamping part of the lower layer products, thus affecting the feeding accuracy, reliability and continuity.

[0006] In a first aspect, this utility model provides a home textile product feeding unit to solve the above-mentioned technical problems, including a connected mounting flange and a transfer assembly. The transfer assembly can drive the mounting flange to move up and down and horizontally. It also includes: a suction cup assembly, which includes a suction cup disposed on the end face of the mounting flange and can be connected to a control air circuit; and a flexible gripper assembly, which includes at least two flexible fingers, with multiple flexible fingers disposed on the end face of the mounting flange and surrounding the suction cup, and the flexible fingers can be connected to a control air circuit.

[0007] This invention uses suction cups to provide planar adsorption force to stabilize the fabric body, while flexible grippers wrap around the product from all sides. On the one hand, when gripping the fabric, the upper product is first separated from the lower product through the synergistic action of the suction cups and the transfer components. After separation, the flexible grippers then hold the fabric, which can effectively avoid wrinkles caused by the flexible grippers directly holding the lower product, ensuring the accuracy, reliability and continuity of the feeding. On the other hand, it forms a dual fixing mechanism of "central adsorption + multi-point gripping", which effectively prevents the fabric from sliding, shifting or falling off in high-speed movement or complex paths.

[0008] Furthermore, the mounting flange is provided with corresponding adjustment holes, which are straight slot holes. The adjustment holes are connected to a connecting block by adjustment bolts. The flexible finger includes a mounting base, which is movably mounted on the connecting block. The adjustment direction of the mounting base on the connecting block is perpendicular to the adjustment direction of the connecting block and the mounting flange.

[0009] This invention, through adjustment holes and mounting bases, allows for adjustment of the position of the flexible fingers on the mounting flange according to the material and thickness of the home textile products, ensuring smooth clamping.

[0010] Furthermore, four flexible fingers are provided.

[0011] Furthermore, the transfer assembly employs a robotic arm, and the actuator of the robotic arm is connected to the mounting flange via a connecting shaft.

[0012] Furthermore, the robotic arm is a six-axis robotic arm.

[0013] Secondly, this utility model also provides a home textile product feeding device, including two of the above-mentioned home textile product feeding units, two robotic arms arranged opposite to each other, and the two home textile product feeding units are capable of gripping two feeding clamping parts of the home textile product respectively.

[0014] This invention enables the feeding of home textile products in a flat manner by setting up two home textile product feeding units, ensuring the smooth operation of processes such as ironing, lint removal, and quality inspection.

[0015] Furthermore, it also includes a control air path one, which includes an air pipe one. Along the air intake direction, the air pipe one is connected to the suction cup in sequence through a solenoid valve one and a vacuum generator. A negative pressure gauge is also connected between the solenoid valve one and the vacuum generator.

[0016] This invention can monitor whether the suction cup assembly can reliably perform suction work by setting a negative pressure gauge.

[0017] Furthermore, it also includes a second control air path, which includes a second air tube. The second air tube is connected to four bypasses via a second solenoid valve, and the four bypasses are respectively connected to the corresponding flexible fingers.

[0018] Furthermore, it also includes a support frame, which has a U-shaped structure and is positioned along the product movement direction. The support frame is located between the two robotic arms and the stack of products. The support frame includes horizontally arranged support rods. The length of the support rods is not less than the distance between the two robotic arms, and the height of the support rods is greater than the height of the stack of products. The products can reach the loading position via the support rods.

[0019] This invention, by setting up a support rod, can lift the upper layer of products, reduce the contact area between the upper and lower layers of products during the transfer process, thereby reducing the friction between the products and ensuring that the loading position of the lower layer of products will not move due to the transfer of the upper layer of products, further ensuring the accuracy and continuity of loading.

[0020] Furthermore, the support rod is fitted with a scratch-resistant sleeve.

[0021] As can be seen from the above technical solutions, this utility model has the following advantages:

[0022] This utility model provides a feeding unit and device for home textile products. Suction cups provide planar adsorption force to stabilize the fabric body, while flexible grippers wrap around the product from all sides. Firstly, when gripping the fabric, the upper layer can be first lifted by the suction cups and separated from the lower layer. After separation, the flexible grippers then hold the fabric, effectively preventing wrinkles caused by direct gripping of the lower layer and ensuring accurate, reliable, and continuous feeding. Secondly, it forms a dual fixing mechanism of "central adsorption + multi-point gripping," effectively preventing the fabric from sliding, shifting, or falling off during high-speed movement or complex paths. Adjustment holes and mounting bases allow for... Adjust the position of the flexible fingers on the mounting flange according to the material and thickness of the home textile products to ensure smooth clamping; by setting up two home textile product feeding units, it is possible to feed the products in a flat manner, ensuring the smooth operation of ironing, lint removal, quality inspection and other processes; by setting up a negative pressure gauge, it is possible to monitor whether the suction cup assembly can reliably perform its suction work; by setting up a support rod, it is possible to lift the upper layer of products, reduce the contact area between the upper and lower layers of products during the transfer, thereby reducing the friction between the products and ensuring that the feeding position of the lower layer of products will not move due to the transfer of the upper layer of products, further ensuring the accuracy and continuity of feeding.

Detailed Implementation

[0030] 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. Specific Implementation Method 1

[0032] like Figure 1 and Figure 2 As shown, this specific embodiment provides a home textile product feeding unit, including a transfer component 1, a mounting flange 2, a suction cup component 4, and a flexible gripper component 3. The transfer component 1 can drive the mounting flange 2 to move up and down and horizontally. The suction cup component 4 includes a suction cup, which is disposed on the end face of the mounting flange 2 and can be connected to a control air circuit. The flexible gripper component 3 includes at least two flexible fingers 6, and multiple flexible fingers 6 are disposed on the end face of the mounting flange 2 and surround the suction cup. The flexible fingers 6 can be connected to a control air circuit. In this specific embodiment, four flexible fingers 6 are provided. During operation, the suction cup component 4 first adsorbs the product, the transfer component 1 lifts the mounting flange 2, so that the upper product is separated from the lower product, and then the flexible gripper component 3 clamps the product.

[0033] In this specific embodiment, the suction cup assembly 4 provides planar adsorption force to stabilize the fabric body, and the flexible gripper assembly 3 wraps around the product from all sides. On the one hand, when gripping the fabric, the upper product is first separated from the lower product through the synergistic action of the suction cup and the transfer assembly 1. After separation, the flexible gripper assembly 3 then clamps the product, which can effectively avoid the phenomenon of wrinkles caused by the flexible gripper assembly 3 directly clamping the lower product, ensuring the accuracy, reliability and continuity of the feeding. On the other hand, a dual fixing mechanism of "central adsorption + multi-point clamping" is formed, which effectively prevents the fabric from sliding, shifting or falling off in high-speed movement or complex paths.

[0034] like Figures 2 to 4As shown, due to the diverse materials and varying thicknesses of home textile products, to improve the applicability of this feeding assembly, in this specific embodiment, the mounting flange 2 is provided with corresponding adjustment holes 201. There are two adjustment holes 201, which are straight slots. The adjustment holes 201 are connected to a connecting block 202 via adjustment bolts 5. The flexible finger 6 includes a mounting base 7 and a clamping airbag. The mounting base 7 is movably mounted on the connecting block 202, and the adjustment direction of the mounting base 7 on the connecting block 202 is perpendicular to the adjustment direction of the connecting block 202 on the mounting flange 2. Specifically, the connecting block 202 is provided with screws... The adjusting bolt 5 is screwed into the screw hole at one end and extends out of the adjusting hole 201 at the other end. The mounting base 7 has an L-shaped structure, including a vertically arranged mounting part 702 and a horizontally arranged connecting part 701. The connecting part 701 is provided with a groove 703. The cross-section of the groove 703 is T-shaped. The connecting block 202 can extend into the groove 703. The connecting part 701 is also provided with a locking bolt. The locking bolt can extend into the groove 703 from one side and abut against the side of the connecting block 202 to achieve position locking. The airbag is connected to the mounting part 702 by bolts. The inner side of the fingertip of the airbag is provided with anti-slip texture.

[0035] like Figure 1 As shown, the transfer component 1 can adopt a three-dimensional conveying mechanism, including a conveyor frame. A crossbeam is set on the conveyor frame via guide rails. A motor is set on the crossbeam. Through a gear and rack mechanism, the motor can drive the crossbeam to move. A movable seat is set on the crossbeam via guide rails. A motor is set on the movable seat. Through a gear and rack mechanism, the motor can drive the movable seat to move. The moving direction of the movable seat is perpendicular to the moving direction of the crossbeam. A lifting plate is set on the movable seat via a motor + screw mechanism. A mounting flange 2 is installed at the lower part of the lifting plate, which can realize the lifting, lateral movement and longitudinal movement of the mounting flange 2. In this specific embodiment, in order to reduce space occupation and improve the flexibility of use, the transfer component 1 adopts a robotic arm. The execution end of the robotic arm is connected to the mounting flange 2 via a connecting shaft 8. To ensure the flexibility of operation, the robotic arm is a six-axis robotic arm.

[0036] In this specific embodiment, both the flexible gripper assembly 3 and the suction cup assembly 4 are existing technologies, and their specific structures and working principles will not be described in detail here. Specific Implementation Method Two

[0038] like Figure 4 As shown, this specific embodiment provides a home textile product feeding device, including two home textile product feeding units of Specific Embodiment 1, two robotic arms arranged opposite to each other, and the two home textile product feeding units can respectively grab two feeding clamping parts of the home textile product.

[0039] This specific embodiment sets up two home textile product feeding units, which can clamp the two feeding clamping parts at the end of the product during feeding, so that the end is flat. This enables feeding in a flat manner, avoiding wrinkles and ensuring the smooth progress of ironing, lint removal, quality inspection and other processes.

[0040] Furthermore, this specific embodiment also includes a control air path one, which includes an air pipe one. One end of the air pipe one is connected to an air source. Along the air intake direction, the air pipe one is connected to the suction cup in sequence through a solenoid valve one and a vacuum generator. The solenoid valve one controls the air intake and exhaust of the suction cup assembly 4. A negative pressure gauge is also connected between the solenoid valve one and the vacuum generator. The negative pressure gauge can transmit the monitored pressure to the control terminal, so that personnel can monitor the adsorption status of the suction cup assembly 4 through the negative pressure gauge. When the product cannot be adsorbed, the parameters can be adjusted or replaced in time to ensure smooth feeding.

[0041] Preferably, this specific embodiment also includes a second control air path, which includes a second air tube. One end of the second air tube is connected to an air source. The second air tube is connected to four bypasses through a second solenoid valve. The four bypasses are respectively connected to the corresponding flexible fingers 6. The second solenoid valve controls the intake and exhaust of the gripping airbag of the flexible fingers 6 to achieve gripping and release.

[0042] Because the stacked products are placed flat at the loading position, the contact area between adjacent layers is large, resulting in significant friction. When the upper layer is moved, the lower layer inevitably moves as well. This causes the loading position of the lower layer to shift, making it difficult for the robotic arm to grip the loading area, resulting in inaccurate positioning on the production line and affecting subsequent processes. Therefore, in this specific embodiment, a support frame is also included. The support frame has a U-shaped structure and is positioned between the two robotic arms and the stacked products along the product movement direction. The support frame includes horizontally arranged support rods 9. To reduce frictional resistance, the support rod 9 is rotatably mounted at the ends of the support frame's uprights via bearings. The length of the support rod 9 is not less than the distance between the two robotic arms, and the height of the support rod 9 is greater than the height of the stacked products. Products can reach the loading position via the support rod 9. The support rod 9 is fitted with a scratch-resistant sleeve made of hard plastic. During the robotic arm's transfer process, the support rod 9 can support the products being transferred, reducing the contact area between the upper and lower products, thereby reducing friction between the products and ensuring that the loading position of the lower product will not move due to the transfer of the upper product, further ensuring the accuracy and continuity of loading.

[0043] Understandably, the size of the home textile products can be input through the control terminal, and the robotic arm can automatically position the feeding position according to the product size. As long as the stack of products is placed in place, accurate feeding can be achieved. Therefore, setting a positioning block at the feeding position can position the material rack 10 that holds the stack of products.

[0044] The working process of this device is as follows:

[0045] During loading, the robotic arm moves to the loading position, the suction cup assembly 4 adsorbs the product, the robotic arm is slightly raised, the flexible gripper gathers and grabs the product, the robotic arm is raised above the support rod, and then moves horizontally to transfer the product. At this time, the product is raised under the support of the support frame and separates from the lower product. After the robotic arm moves horizontally to the position, the flexible gripper assembly 3 releases the grip, the suction cup assembly 4 releases the air, and the product clamping part is placed in the corresponding position on the production line.

[0046] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0047] 1. The suction cup provides planar adsorption force to stabilize the main body of the fabric. The flexible gripper assembly 3 wraps around the product from all sides. On the one hand, when gripping the fabric, the upper product can be first picked up by the suction cup and separated from the lower product. After separation, the flexible gripper assembly 3 clamps it, which can effectively avoid the phenomenon of wrinkles caused by the flexible gripper directly clamping the lower product, ensuring the accuracy, reliability and continuity of feeding. On the other hand, a dual fixing mechanism of "central adsorption + multi-point clamping" is formed, which effectively prevents the fabric from sliding, shifting or falling off in high-speed movement or complex path.

[0048] 2. By adjusting the holes and mounting base 7, the position of the flexible fingers 6 on the mounting flange 2 can be adjusted according to the material and thickness of the home textile products to ensure smooth clamping;

[0049] 3. By setting up two home textile product feeding units, it is possible to feed the products in a flat manner, ensuring the smooth operation of processes such as ironing, lint removal, and quality inspection;

[0050] 4. By setting a negative pressure gauge, it is possible to monitor whether the suction cup assembly 4 can reliably perform suction work;

[0051] 5. By setting the support rod 9, the upper layer product can be lifted, reducing the contact area between the upper and lower layers during the transfer process, thereby reducing the friction between the products and ensuring that the loading position of the lower layer product will not move due to the transfer of the upper layer product, further ensuring the accuracy and continuity of loading.

[0052] 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.
