Description

Technical Field

[0001] This utility model relates to shoe manufacturing equipment, specifically to a feeding device for a shoe sole pressing machine. Background Technology

[0002] In the footwear industry, automatic edge-sealing and pressing machines are used to press and bond the side panels of shoes to ensure a strong bond. Currently, most production lines use a fixed-height shoe input conveyor in conjunction with the edge-sealing and pressing machine. Because the conveyor height varies between different production lines, the input height of the edge-sealing and pressing machine needs to be customized individually. This forces equipment manufacturers to redesign and process for each production line, increasing material waste and labor costs, and extending delivery cycles. Furthermore, existing equipment often only performs edge-sealing and pressing on one side or a portion of the shoe, making it difficult to simultaneously complete multi-directional edge-sealing in a single process, affecting production efficiency and product quality stability.

[0003] Therefore, there is an urgent need for an automated device that can flexibly adapt to different conveyor heights and complete multi-directional edge pressing of shoes in one go, so as to reduce customization costs and improve versatility and production efficiency. Utility Model Content

[0021] like Figure 1 — Figure 6 As shown, this embodiment discloses a feeding device for a shoe sole pressing machine, including a frame 101, a shoe sole pressing station 102, a shoe input conveyor 103, a first conveyor 104, and a liftable second conveyor 105.

[0022] 1. Overall Layout

[0023] The first conveyor 104 is located in front of the sole pressing station 102, and the second conveyor 105 is located at the input end of the first conveyor 104 and connected to the shoe input conveyor 103 connected at a higher position. A conveying assembly is provided between the first conveyor 104 and the second conveyor 105 to smoothly transfer the shoes on the second conveyor 105 to the first conveyor 104, and then the robotic arm 117 will transfer them to the sole pressing station 102.

[0024] 2. Shoe input conveyor 103 structure

[0025] The shoe input conveyor 103 includes a first support 113, on which a first transmission belt 114 driven by a first motor is mounted. The first transmission belt 114 is arranged in a continuous conveying surface. A first side frame 115 is fixed to the side of the first transmission belt 114, and multiple first rollers 116 are arranged in a straight line facing the side wall of the first transmission belt 114. The first rollers 116 prevent the shoes from shifting during conveying and reduce contact friction to avoid damage to the shoe upper. Workers place the finished shoe pieces on the first transmission belt 114, which is then driven by the first motor to be fed into the second conveyor 105.

[0026] 3. Structure and lifting principle of the second conveyor platform 105

[0027] The second conveyor 105 includes a vertical linear motion module 106 mounted vertically on the frame 101, with its slider fixedly connected to a slide block 107. A second transmission belt 108 driven by a second motor is mounted on the slide block 107, and the second transmission belt 108 is arranged around to form a conveying surface. A second side frame 109 is fixed to the side of the second transmission belt 108, and the second side frame 109 has second rollers 110 arranged sequentially facing the side wall of the second transmission belt 108, which function similarly to the first rollers 116. A linearly arranged conveyor guide roller 111 is installed at the output end of the second transmission belt 108.

[0028] The vertical linear motion module 106 can drive the slide 107 and the entire second conveyor 105 to rise and fall in the vertical direction, thereby adjusting the height of the second transmission belt 108 so that it can smoothly connect with the high shoe input conveyor 103 and dock with the low first conveyor 104, realizing a flexible transition between conveyor platforms of different heights and avoiding repeated customization of the input end height.

[0029] 4. First teleportation station 104 and teleportation components

[0030] The first conveyor platform 104 includes several transversely arranged and surrounding third transmission belts 112, which are independently driven by a third motor. Conveyor guide rollers 111 are located at the output end of the second transmission belt 108 and can float up and down along the intervals between the third transmission belts 112, thereby maintaining smooth connection with the second transmission belt 108 and the third transmission belts 112 when the height changes, achieving impact-free transfer of shoes from the second conveyor platform 105 to the first conveyor platform 104.

[0031] 5. Robotic Arm 117

[0032] A robotic arm 117 is installed between the first conveyor 104 and the sole pressing station 102. The robotic arm includes a linear motion module. A sliding bracket is installed on the slider of the linear motion module. A feeding gripper 140 is installed on one side of the bracket, and a discharging gripper 150 is installed on the other side. The feeding gripper 140 and the discharging gripper 150 have the same structure. Both are driven by a cylinder to open and close the two clamping plates to realize the gripping, transfer and unloading of shoe parts.

[0033] 6. Structure of sole pressing station 102

[0034] The sole pressing station 102 includes a base 118. Shoe side edge pressing blocks 119 are symmetrically arranged on the left and right sides of the upper surface of the base 118, and shoe end edge pressing blocks 120 are symmetrically arranged on the front and back sides.

[0035] Lateral movement mechanism: A lateral guide rail 122 is provided on the base 118, and two lateral sliders 123 are provided on the guide rail. Each lateral slider 123 is connected to the corresponding shoe end edge pressing block 120 through the connecting seat 124, and is pushed by the first driving device (cylinder) to slide along the lateral guide rail 122 to achieve multi-point synchronous pressing of the shoe end.

[0036] Longitudinal moving mechanism: The base 118 is also equipped with a longitudinal guide rail, and two longitudinal sliders 127 are provided on the guide rail. The two shoe side edge pressing blocks 119 are respectively fixed on the corresponding longitudinal sliders 127 and pushed by the second drive device (cylinder) to slide along the longitudinal guide rail to complete the synchronous pressing of the shoe side.

[0037] Linkage control: The two first drive devices are connected to the air pump through a solenoid valve, and the two second drive devices are connected to the air pump through another solenoid valve, ensuring that the pressing blocks on the same side move in unison and are subjected to uniform force.

[0038] Bottom pressing mechanism: The end face of the base 118 is provided with slots 129 arranged in sequence. A lifting block 130 is provided below the base 118. A top block 121 that can pass through the slots 129 is mounted on the lifting block 130. The top block 121 is adapted to the shape of the slots 129 and its height is greater than the depth of the slots 129. It can extend upward under the drive of the lifting cylinder 131 to press the sole from the bottom surface, so that the sole and the upper are fully bonded.

[0039] 7. Work Process

[0040] (1) The worker places the hemmed shoe pieces on the first transmission belt 114 of the shoe input conveyor 103, and the first motor transports them to the second conveyor 105.

[0041] (2) The vertical linear motion module 106 adjusts the lifting position of the second conveyor 105 according to the actual height of the production line so that it smoothly connects with the second transmission belt 108 and the third transmission belt 112 of the first conveyor 104.

[0042] (3) The second transmission belt 108 transports the shoe parts to the output end, and guides them into the third transmission belt 112 section of the first transmission table 104 via the conveyor guide roller 111.

[0043] (4) The feeding gripper 140 of the robot arm 117 picks up the shoe piece and transfers it to the center position of the base 118 of the shoe sole pressing station 102 via the linear motion module.

[0044] (5) The first driving device pushes the shoe end edge pressing block 120 to clamp the shoe end along the transverse guide rail 122, and the second driving device pushes the shoe side edge pressing block 119 to clamp the shoe side along the longitudinal guide rail, so as to realize the synchronous edge pressing of the shoe side and shoe end.

[0045] (6) The lifting cylinder 131 drives the lifting block 130 to rise, and the top block 121 passes through the through slot 129 to press the sole, so that the sole and the bottom area of ​​the upper are tightly bonded.

[0046] (7) After pressing, the discharge clamp 150 removes the finished shoe and proceeds to the next process.

[0047] With the above structure, this device achieves adaptive docking of conveyor platforms of different heights, eliminating the need for repeated customization, and completing the synchronous pressing of the shoe side, shoe end and sole in one process, thereby improving production efficiency and bonding quality.
