Description

Technical Field

[0001] This utility model relates to the field of intelligent manufacturing or shoemaking technology, and in particular to a separation and palletizing device for shoe tongues. Background Technology

[0002] In the shoe manufacturing industry, the production, processing, and transportation of shoe tongues are an important part of shoemaking, especially for shoes with laces. The shoe tongue is an important component of the shoe, serving as the part between the bottom of the shoelaces and the top of the foot, and reducing friction between the shoelaces and the instep. Generally, the shoe tongue is a separate piece of material on the shoe upper. Usually, a label containing the shoe brand's logo or QR code is printed on the shoe tongue.

[0003] The cutting process of the shoe tongue results in freshly produced shoe tongues being in a state of two layers attached together, which needs to be separated. Currently, the separation of the double-layered shoe tongues is mostly done manually. This requires manually separating each layer of the tongue, arranging them neatly, and finally applying heat-pressed labels. Manual separation is labor-intensive and inefficient.

[0004] In summary, the existing technology has the following technical problems:

[0005] 1. Separating the shoe tongue is done manually, requiring a large amount of labor;

[0006] 2. Low separation efficiency. Utility Model Content

[0045] Exemplary embodiments of the present invention are described in detail below with reference to the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements. Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the drawings.

[0046] The current shoe tongues are manufactured as two tongues attached together, and need to be separated. Figure 1 A separating and stacking device 100 for shoe tongues is shown, which is used to separate and neatly stack double-layer shoe tongues, such as... Figure 1 As shown, the separating and palletizing device 100 includes a fixed frame 1, a conveyor 3, a tongue supply unit 2, a robotic arm 4, and a tongue separation unit 5. The fixed frame 1 is a square frame that directly or indirectly supports all components of the separating and palletizing device 100. The conveyor 3 is fixed to the fixed frame 1 and installed on the opposite side of the tongue supply unit 2. It is used to transport the disassembled and neatly stacked tongues away from the palletizing position. The tongue supply unit 2 is placed upstream of the conveyor 3 and installed on the fixed frame 1. It is used to store and supply tongues and is responsible for supplying tongues to the robotic arm 4. The tongue separation unit 5 is installed between the conveyor 3 and the tongue supply unit 2. It is used to work with the robotic arm 4 to complete the separation of the tongues. It is used to grab the lower layer of the double-layered tongue when separating the tongues. The robotic arm 4 is installed above the tongue separation unit 5. It is responsible for taking the tongues out of the tongue supply unit 2 and working with the tongue separation unit 5 to complete the separation of the tongues. Finally, the tongues are palletized on the conveyor 3.

[0047] The shoe tongue separation unit 5 includes a separation platform 18 and a third needle-type suction cup 17. The separation platform 18 is fixed on the fixed frame 1. The separation platform 18 has square holes, and the number of square holes can be multiple. In the illustrated example, there are two square holes. Each square hole of the separation platform 18 is equipped with a third needle-type suction cup 17. Note that the third needle-type suction cup 17 is used to fix the lower layer of the shoe tongue when separating it. The number of square holes is the same as the number of third needle-type suction cups 17, and the positions of the square holes correspond to the positions of the third needle-type suction cups 17.

[0048] The shoe tongue supply unit 2 is mounted on the fixed frame 1 and is used to store and supply shoe tongues. It utilizes a drive mechanism and sensors to control the height of the shoe tongue within the supply unit 2, ensuring that the height of the shoe tongue within the supply unit 2 is always the same as the upper surface of the shoe tongue separation unit 5, thus facilitating the picking up of the shoe tongue by the robotic arm 4. The shoe tongue supply unit 2 is not the focus of this invention; it can be implemented using existing technology, as described in the inventor's previous utility model patents.

[0049] According to an embodiment of this utility model, the robotic arm 4 includes: a drive base 6; an operating arm, which is convexly connected to the drive base 6 and driven by the drive base 6; at least two first needle-type suction cups 7 for adsorbing the upper shoe tongue; and at least two second needle-type suction cups 8 for adsorbing the lower shoe tongue. The robotic arm 4 also includes a mounting plate 9, on which at least two of the first needle-type suction cups 7 and at least two of the second needle-type suction cups 8 are fixedly mounted. The operating arm includes: a first arm 10, which is convexly connected to the drive base 6 and configured to rotate about an axis; a second arm 11, whose two ends are hinged to the first arm 10 and the mounting plate 9 respectively; a third arm 12, which is convexly connected to the drive base 6 and configured to rotate about an axis; and a fourth arm 13, whose two ends are hinged to the third arm 12 and the mounting plate 9 respectively. It should be noted that the robotic arm 4 is not the focus of this utility model; it can be implemented using existing equipment, as described in the inventor's previous utility model patents.

[0050] Furthermore, the robotic arm 4 also includes a stationary platform 14, which is mounted on the drive base 6. The first arm 10 and the third arm 12 are respectively connected to the drive base 6 via the stationary platform 14. The operating arm also includes a first adjusting rod 15 and a second adjusting rod 16. The combination of the first adjusting rod 15 and the second adjusting rod 16 is used to adjust the mounting plate 9 so that the mounting plate 9 always remains horizontal. One end of the second adjusting rod 16 is hinged to the stationary platform 14. The first adjusting rod 15 and the second adjusting rod 16 are connected by a triangular plate, and the lower end of the first adjusting rod 15 is hinged to the mounting plate 9.

[0051] The robotic arm 4 includes a first needle-type suction cup 7 and a second needle-type suction cup 8. These are two types of needle-type suction cups that perform different functions during the operation of the separation and palletizing device 100. They are fixed together and can always move synchronously. The first needle-type suction cup 7 can remove the shoe tongue from the shoe tongue supply unit 2 and place it in the shoe tongue separation unit 5. At this time, the third needle-type suction cup 17 in the shoe tongue separation unit 5 grabs the lower layer of the double-layer shoe tongue. The first needle-type suction cup 7 moves upward to separate the double-layer shoe tongue. After separation, the third needle-type suction cup 17 releases the lower layer of shoe tongue, and then the second needle-type suction cup 8 removes the lower layer of shoe tongue placed on the shoe tongue separation unit 5. The distance between the two needle-type suction cups is the same as the distance between the third needle-type suction cup 17 and the shoe tongue supply unit 2, and the height of the shoe tongue in the shoe tongue supply unit 2 is the same as the height of the upper surface of the shoe tongue separation unit 5. This allows the second needle-type suction cup 8 to simultaneously grab the lower layer of shoe tongue left in the shoe tongue separation unit 5 while the first needle-type suction cup 7 grabs the shoe tongue in the shoe tongue supply unit 2.

[0052] When the robotic arm 4 controls the mounting plate 9 to move, since the first needle suction cup 7 and the second needle suction cup 8 (two in the illustrated embodiment) are mounted on the mounting plate 9, they move synchronously. First, the first needle-type suction cup 7 moves above the tongue supply unit 2, while the second needle-type suction cup 8 moves above the square hole of the separation platform 18. The first needle-type suction cup 7 is controlled to suck (vacuum), which can suck up the double-layer tongue (not separated, attached together) on the tongue supply unit 2. Then, the robot arm 4 moves the mounting plate 9, so that the second needle-type suction cup 8 moves above the conveyor 3 while the first needle-type suction cup 7 moves above the square hole of the separation platform 18. Since the third needle-type suction cup 17 is located in the square hole, the third needle-type suction cup 17 is controlled to suck (vacuum), so the upper layer of the double-layer tongue is held on the first needle-type suction cup 7, while the lower layer of the double-layer tongue is sucked by the third needle-type suction cup 17. When the first needle-type suction cup 7 moves upward, the two layers of tongue separate. Then the mounting plate 9 is moved above the conveyor 3, and the first needle-type suction cup 7 is controlled to release the tongue. Then, the mounting plate 9 moves so that the first needle suction cup 7 moves above the shoe tongue supply unit 2, while the second needle suction cup 8 moves above the square hole of the separation platform 18. The first needle suction cup 7 picks up the next double-layer shoe tongue, and the second needle suction cup 8 picks up the lower layer shoe tongue left on the separation platform 18 in the previous step. Then, the upward movement of the first needle suction cup 7 is repeated to separate the double-layer shoe tongue. Then, the mounting plate 9 is moved above the conveyor 3, and the first needle suction cup 7 and the second needle suction cup 8 are controlled to release the shoe tongue synchronously. This process is repeated.

[0053] The conveyor 3 is mounted on the fixed frame 1. The robotic arm 4 places the separated shoe tongues onto the conveyor 3. The conveyor 3 is set to move intermittently. When the conveyor 3 is stationary, the robotic arm 4 places the shoe tongues in the same position on the conveyor 3, so that the shoe tongues are neatly stacked together. That is, when the conveyor 3 stops moving, the robotic arm 4 can stack the shoe tongues. After the shoe tongues are stacked, the conveyor 3 starts moving and sends the shoe tongues out of the stacking area. Each time the robotic arm 4 places a shoe tongue, the stacking height of the shoe tongues increases by one shoe tongue thickness. The number of shoe tongues can be controlled by the stacking height. After a certain number of shoe tongues have accumulated, they are sent away from the stacking position for manual sorting, which can reduce the workload of manual sorting of shoe tongues.

[0054] Advantageously, the distance between the third needle suction cup 17 and the tongue supply position of the tongue supply unit 2 is equal to the distance between the first needle suction cup 7 and the second needle suction cup 8. There are multiple first needle suction cups 7, multiple second needle suction cups 8, and multiple third needle suction cups 17; the distance between adjacent first needle suction cups 7 is the same as the distance between adjacent second needle suction cups 8, and also the same as the distance between adjacent third needle suction cups 17.

[0055] This invention provides a separation and stacking device for shoe tongues. This device can automatically complete the separation and stacking of double-layer shoe tongues, effectively reducing manual labor and improving the automation level and efficiency of shoe tongue processing. The double-layer shoe tongue separation and stacking device is an automated device capable of separating double-layer shoe tongues and neatly stacking the separated tongues. Its existence greatly improves the mechanization and automation of shoe manufacturing.

[0056] This invention provides a separating and stacking device for shoe tongues, which can quickly separate double-layered shoe tongues and then stack them neatly. Shoe tongues processed by this device can be directly placed into a labeling device for labeling. It can replace manual separation of shoe tongues and reduce the time spent manually arranging them.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
