Description

Technical Field

[0001] This utility model relates to the field of shoe support technology, and in particular to a shoe support machine that integrates material handling and stacking. Background Technology

[0002] A shoe tree is an inner mold used to support the upper of a shoe and maintain its shape. It is typically made of plastic through a thermoforming process. In the automated production of shoe trees, a shoe tree forming machine uses the closing action of an upper and lower mold base to form a three-dimensional shoe tree with a toe, body, and heel structure. After forming, the shoe trees need to be removed from the mold and stacked for subsequent packaging and transportation.

[0003] Currently, existing shoe tree machines that integrate material handling and stacking typically use a horizontal stacking method in the discharge stage: the discharge suction cup removes the formed shoe tree from the mold, moves it to the unloading area, and releases it horizontally, allowing the shoe tree to lie flat on the unloading table. Then, subsequent shoe trees are stacked directly on top of the previous one. However, for shoe trees with heel structures (i.e., the rear end of the shoe tree has a concave structure that matches the heel of the shoe), the concave structure at the heel can easily cause misalignment and collision between the upper and lower shoe trees during horizontal stacking, resulting in unstable stacking. In practice, for shoe trees with heels, a tilted stacking method is usually adopted, with the front end raised and the rear end on the ground, so that the concave structure at the heel faces upward to support the next shoe tree, thereby achieving stable vertical stacking. For ordinary shoe trees without heels, no tilting is required; they can be placed horizontally to achieve vertical stacking.

[0004] However, existing equipment has significant shortcomings when dealing with these two different types of shoe trees: when handling shoe trees without heels, there is no need to set up a tilting stop, and the shoe tree must be released horizontally onto the unloading platform surface. Since the release height of the suction cups is usually fixed, if the height of the unloading platform is not adjustable, as the number of stacked layers increases, the falling distance of the shoe tree when released from the suction cup will become increasingly larger, easily leading to shoe tree misalignment, uneven stacking, or even scattering. For shoe trees with heels, there are also specific requirements for the initial receiving height of the unloading platform when stacking at an angle. Existing equipment generally lacks a height-adjustable unloading receiving platform, making it impossible to flexibly adjust the dropping distance according to the type of shoe tree or the stacking height. Therefore, it is difficult to simultaneously meet the requirements of both tilted stacking of shoe trees with heels and horizontal stable stacking of shoe trees without heels, limiting the versatility of the equipment and the stacking quality. Utility Model Content

[0005] The purpose of this invention is to provide a shoe tree machine that integrates material handling and stacking, in order to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A shoe tree machine integrating material handling and stacking includes a frame. The frame is equipped with a lower mold base, an upper mold base, a mold base drive component, a discharge suction cup, and a discharge drive component. The lower mold base is fixed to the frame, and the upper mold base is located directly above it. The mold base drive component is connected to the upper mold base to drive the upper mold base to move up or down towards or away from the lower mold base. The discharge suction cup is used to pick up or release shoe trees formed by the lower and upper mold bases. The discharge drive component is connected to the discharge suction cup to drive the discharge suction cup to move.

[0008] The frame is equipped with a lifting platform, and the lifting platform has at least one set of unloading stations. Each unloading station includes two opposing baffles, forming an unloading area between the two baffles. A baffle is provided in the unloading area, and the baffle is movably inserted through the baffle and can extend into or out of the unloading area, so that the shoe support can be placed at an angle on the baffle, or placed horizontally at the bottom of the unloading area when the baffle is out of the unloading area. The lifting platform is driven by a lifting drive assembly to achieve lifting and lowering, thereby adjusting the height position of the shoe support relative to the discharge suction cup in different placement states.

[0009] By adopting the above technical solution, and by setting a stop bar on the lifting platform that can extend into or retract from the unloading area, the unloading area has two working modes: when the stop bar is extended, the shoe supports can be placed at an angle on the stop bar, achieving stable tilted stacking of shoe supports with heels raised at the front and lowered at the rear; when the stop bar is retracted, the shoe supports can be placed horizontally at the bottom of the unloading area, meeting the horizontal stacking requirements of shoe supports without heels. Simultaneously, by driving the lifting platform as a whole through the lifting drive component, the relative height between the shoe supports at the bottom of the unloading area or on the stop bar and the discharge suction cup can be adjusted according to different placement states and stacking heights of the shoe supports, thereby controlling the dropping distance when the shoe supports are released and preventing the shoe supports from shifting or scattering due to excessive dropping height. This application can accommodate the stacking requirements of both shoe supports with and without heels, and ensure the neatness of dropping under different stacking methods, significantly improving the versatility and stacking quality of the equipment.

[0010] A further configuration is as follows: the lifting drive assembly includes a lifting screw and a handwheel drive seat; the two sides of the lifting platform are slidably guided to the frame via guide rods; the lifting screw is rotatably mounted on the bottom of the lifting platform and threadedly connected to the handwheel drive seat.

[0011] By adopting the above technical solution, and by setting up a lifting screw, a handwheel drive seat, and a guide rod guiding structure, the two sides of the lifting platform slide against the frame via guide rods. The lifting screw is rotatably installed at the bottom of the lifting platform and is threadedly driven by the handwheel drive seat. The operator can rotate the handwheel of the handwheel drive seat to drive the lifting screw to rotate, thereby driving the lifting platform to rise and fall smoothly. The structure is simple and the operation is labor-saving.

[0012] A further feature is that an oblique adjustment hole is provided on the outer side of the baffle plate, and the baffle rod extends into the feeding area after passing through the adjustment hole. The baffle rod can be slidably adjusted along the length direction of the adjustment hole.

[0013] By adopting the above technical solution, the tilt angle can be flexibly adjusted according to different models or sizes of shoe trees, ensuring that the orientation and opening size of the concave structure at the heel of the shoe tree always match the shoe trees to be stacked, so that shoe trees of different specifications can obtain the best stacking posture.

[0014] A further feature is that a connecting support fixed to the frame is provided on the outer side of the baffle, and the connecting support has a mating hole corresponding to the adjustment hole; the stop rod is fixed to the connecting support, thereby maintaining the stability of the support height after the position of the stop rod is adjusted.

[0015] By adopting the above technical solution, the baffle bar can be effectively prevented from shifting, shaking or deflecting during the impact of the shoe support falling or during long-term use, thus ensuring that the baffle bar is in the preset support position each time it is stacked, and ensuring the consistency of the shoe support stacking posture.

[0016] A further feature is that a linear actuator is fixedly mounted on the connecting support, and the stop bar is the output shaft of the linear actuator.

[0017] By adopting the above technical solution, the automatic retraction of the stop bar can be achieved, providing flexibility for subsequent material discharge or avoidance actions.

[0018] A further feature is that the frame is also provided with two material collection areas separated by extension plates, and the material collection areas are connected to the material collection areas; the material discharge drive is also provided with a lever driven by it, and the lever can move to the outer side of the heel of the shoe support at the rear end in the material collection area under the drive of the material discharge drive, and then push the shoe support to the material collection area.

[0019] By adopting the above technical solution, when a set of shoe supports is stacked to a certain number in the unloading area, the lever can be moved to the outer side of the heel of the shoe support at the rear end of the unloading area under the drive of the unloading drive component, and smoothly push the entire set of shoe supports into the unloading collection area, thereby clearing the unloading area in time for the stacking of the next set of shoe supports, realizing continuous stacking and collection operations.

[0020] A further feature is that the discharge drive unit includes a first cylinder and a second cylinder that can respectively control the lifting and lowering of the discharge suction cup and the lever to achieve obstacle avoidance.

[0021] By adopting the above technical solution, the discharge suction cup and the lever are controlled by the first cylinder and the second cylinder respectively, complementing each other and enabling them to move independently.

[0022] A further configuration is as follows: the discharge drive component includes a drive motor fixedly mounted on the top of the frame, the output shaft of the drive motor is provided with drive teeth, a transmission belt that meshes with the drive teeth is provided on the frame, a connecting plate is fixedly mounted on the transmission belt, a stroke seat is fixedly mounted on the connecting plate, the lever and the discharge suction cup are both mounted on the stroke seat and move with the stroke seat; a guide shaft is provided on the frame for the stroke seat to pass through and serve as a guide.

[0023] By adopting the above technical solution, the horizontal drive control of the lever and the discharge suction cup was achieved.

[0024] In summary, this utility model has the following beneficial effects: When the discharge suction cup moves the shoe support above the stop bar and releases it, the front end of the shoe support will contact the stop bar and be supported by it, while the rear end will naturally sink down, so that the shoe support is placed in an inclined posture with the front end raised and the rear end sinking down. At this time, the concave structure at the heel of the rear end of the shoe support is facing upwards. The subsequent shoe supports will be embedded in the concave structure of the previous shoe support in turn. Thus, the shoe supports can be automatically, neatly, and stably stacked without relying on manual intervention. This effectively solves the problem of random shoe support posture and chaotic stacking when the existing shoe support machine that integrates material picking and stacking is unloading, and provides a uniform and orderly material state for subsequent automated handling or packaging.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figures 1-7 As shown;

[0035] This embodiment discloses a shoe tree machine integrating material handling and stacking, including a frame 11. The frame 11 is equipped with a lower mold base 21, an upper mold base 22, a mold base drive, a discharge suction cup 31, and a discharge drive. The lower mold base 21 is fixed to the frame 11, and the upper mold base 22 is located directly above it. The mold base drive is connected to the upper mold base 22 and is used to drive the upper mold base 22 to move up or down towards or away from the lower mold base 21, thereby completing the stamping and forming of the shoe tree. The discharge suction cup 31 is used to pick up or release the shoe tree formed by the lower mold base 21 and the upper mold base 22. The discharge drive is connected to the discharge suction cup 31 and is used to drive the discharge suction cup 31 to move between workstations on the frame 11, thereby transferring the shoe tree from the mold area to the material handling area 41. It should be noted that the mold base drive can adopt a conventional lifting drive structure in the field, such as any one of hydraulic cylinder, pneumatic cylinder or electric cylinder, and the output shaft can be directly connected to the upper mold base 22. Its specific structure and working principle belong to the prior art.

[0036] A lifting platform 23 is provided on the frame 11, and the lifting platform 23 is provided with at least one set of unloading stations; the unloading station includes two opposing baffles 42, and an unloading area 41 is formed between the two baffles 42; a stop bar 51 is provided in the unloading area 41, the stop bar 51 is movably inserted through the baffles 42 and can extend into or out of the unloading area 41, so that the shoe support can be placed at an angle on the stop bar 51, or placed horizontally at the bottom of the unloading area 41 when the stop bar 51 is out of the unloading area 41; the lifting platform 23 is driven by a lifting drive assembly 24 to achieve lifting and lowering, thereby adjusting the height position of the shoe support relative to the discharge suction cup 31 in different placement states.

[0037] By installing a baffle 51 on the lifting platform 23 that can extend into or retract from the unloading area 41, the unloading area 41 has two working modes: when the baffle 51 is extended, the shoe supports can be placed at an angle on the baffle 51, achieving stable tilted stacking with the front end of the heeled shoe supports raised and the rear end on the ground; when the baffle 51 is retracted, the shoe supports can be placed horizontally at the bottom of the unloading area 41, meeting the horizontal stacking requirements of shoe supports without heels. Simultaneously, the lifting drive assembly 24 drives the lifting platform 23 to lift as a whole, adjusting the relative height between the shoe supports at the bottom of the unloading area 41 or on the baffle 51 and the discharge suction cup 31 according to different placement states and stacking heights of the shoe supports. This controls the dropping distance when the shoe supports are released, preventing the shoe supports from shifting or scattering due to excessive dropping height. This application can accommodate the stacking requirements of both heeled and non-heeled shoe supports, while ensuring the neatness of dropping under different stacking methods, significantly improving the versatility and stacking quality of the equipment.

[0038] When the discharge suction cup 31 moves above the stop bar 51 and releases the shoe support, the shoe support falls under its own weight. At this time, the front end of the shoe support will first contact the stop bar 51 and be supported by it, while the rear end of the shoe support will continue to fall because it is unsupported, until the overall weight of the shoe support is borne by the stop bar 51 and the bottom surface of the discharge area 41. Finally, the shoe support is tilted with the front end raised and the rear end lowered. In this tilted posture, the concave structure at the heel of the shoe support will naturally face upward. This concave structure is used to wrap the heel when molding the shoe body, and at this time, it forms a positioning cavity 61 for receiving the next shoe support. When the second shoe support falls in the same way, its front end will also be supported by the stop bar 51, while its rear end will fall into the positioning cavity 61 of the first shoe support, thereby realizing the automatic fitting and stacking of the upper and lower shoe supports. This process is repeated, with each newly dropped shoe tree stacking on top of the previous one, forming a neat, layered queue of shoe trees. The shoe trees can be automatically stacked and arranged without manual intervention.

[0039] The lifting drive assembly 24 includes a lifting screw 25 and a handwheel drive seat 26. The two sides of the lifting platform 23 are slidably guided to the frame 11 by guide rods 27. The lifting screw 25 is rotatably mounted on the bottom of the lifting platform 23 and is threadedly connected to the handwheel drive seat 26.

[0040] By setting up a lifting screw 25, a handwheel drive seat 26, and a guide rod 27, the two sides of the lifting platform 23 are slidably engaged with the frame 11 via the guide rod 27. The lifting screw 25 is rotatably mounted on the bottom of the lifting platform 23 and threadedly driven by the handwheel drive seat 26. The operator can rotate the handwheel of the handwheel drive seat 26 to drive the lifting screw 25 to rotate, thereby driving the lifting platform 23 to rise and fall smoothly. The structure is simple and the operation is labor-saving. It is understood that although the lifting drive component 24 in this embodiment is described using a handwheel drive screw as an example, it is not the only implementation method. In other embodiments, the lifting drive component 24 can also be electrically adjusted by directly driving the lifting screw 25 to rotate with a motor, or by directly driving the lifting platform 23 to rise and fall with a linear actuator 52 such as a cylinder or electric cylinder. Regardless of whether manual adjustment or automatic drive is used, as long as the height adjustment function of the lifting platform 23 can be achieved, it falls within the protection scope of this application.

[0041] To accommodate the varying support height requirements of different shoe trees of different models or sizes, an oblique adjustment hole 421 is provided on the outer baffle 42. The stop rod 51 passes through the adjustment hole 421 and extends into the feeding area 41. The stop rod 51 can be slidably adjusted along the length of the adjustment hole 421 (i.e., adjusting the position of the linear actuator 52; how to fix it after adjustment is not the focus of this application, but can be achieved by screw connection, etc.), thereby changing its support height in the feeding area 41. By changing the height of the stop rod 51, the tilt angle of the shoe tree when placed at an angle can be adjusted, thereby controlling the orientation and opening size of the concave structure at the heel of the shoe tree's rear end, enabling it to fit well with shoe trees of different sizes, ensuring the stability and consistency of stacking.

[0042] To further improve the support stability of the stop bar 51 after position adjustment, a connecting support 71 fixed to the frame 11 is provided on the outer side of the outer baffle 42. The connecting support 71 has a mating hole 711 corresponding to the adjustment hole 421. The stop bar 51 is fixed to the connecting support 71, thereby maintaining the stability of the support height after the stop bar 51 is adjusted. As a fixing structure for the stop bar 51, the connecting support 71 can effectively prevent the stop bar 51 from shifting or shaking when it is impacted by the shoe support falling, ensuring that the stop bar 51 is in the preset support position every time the shoe support falls, thereby ensuring the consistency of the stacking posture.

[0043] As a more automated implementation, a linear actuator 52 is fixedly mounted on the connecting support 71, and the stop lever 51 serves as the output shaft of the linear actuator 52. The linear actuator 52 can be a cylinder, an electric cylinder, or other drive element capable of linear reciprocating motion. By controlling the extension length of the linear actuator 52, the length of the stop lever 51 extending into the feeding area 41 can be precisely adjusted. This structure enables automated and rapid retraction of the stop lever during subsequent material discharge.

[0044] Furthermore, the frame 11 is also equipped with two unloading collection areas 82 separated by extension plates 81, which are connected to the unloading area 41. The unloading drive unit is also equipped with a lever 32 driven by it. Driven by the unloading drive unit, the lever 32 can move to the outer heel of the rear end of the shoe support in the unloading area 41, and then push the shoe support to the unloading collection area 82. When a group of shoe supports is stacked to a certain number in the unloading area 41, the lever 32 will push the entire stacked group of shoe supports from the unloading area 41 into the adjacent unloading collection area 82, thereby freeing up the unloading area 41 for the continued stacking of subsequent shoe supports.

[0045] The discharge drive unit includes a first cylinder 91 and a second cylinder 92 that can independently control the raising and lowering of the discharge suction cup 31 and the lever 32 to avoid interference. Through the independent control of the first cylinder 91 and the second cylinder 92, the discharge suction cup 31 and the lever 32 can be raised and lowered during horizontal movement to avoid interference with the already stacked shoe supports. For example, when the discharge suction cup 31 needs to move above the unloading area 41 to release the shoe support, the first cylinder 91 drives the discharge suction cup 31 down to the release position. After release, the first cylinder 91 then drives the discharge suction cup 31 up to its reset position. When the lever 32 needs to push the shoe support, the second cylinder 92 drives the lever 32 down to a position contacting the outer side of the heel at the rear end of the shoe support. After pushing, the second cylinder 92 then drives the lever 32 up to its reset position. This separate raising and lowering control method allows the discharge suction cup 31 and the lever 32 to work independently without interference, improving the flexibility and reliability of the equipment.

[0046] The discharge drive unit includes a drive motor 93 fixedly mounted on the top of the frame 11. The output shaft of the drive motor 93 is provided with drive teeth 931. A transmission belt 94 is mounted on the frame 11 and meshes with the drive teeth 931. The inner side of the transmission belt 94 is provided with tooth-like protrusions that match the drive teeth 931. The meshing of the drive teeth 931 and the transmission belt 94 is a very basic structure and is existing technology. A connecting plate 95 is fixedly mounted on the transmission belt 94, and a stroke seat 96 is fixedly mounted on the connecting plate 95. The lever 32 and the discharge suction cup 31 are both mounted on the stroke seat 96 and move with the stroke seat 96. The drive motor 93 drives the transmission belt 94 to rotate through the drive teeth 931. The transmission belt 94 then drives the stroke seat 96 to move horizontally through the connecting plate 95, thereby realizing the reciprocating motion of the lever 32 and the discharge suction cup 31 between the unloading area 41 and the mold area. To ensure the stability and positional accuracy of the travel seat 96 during movement, a guide shaft 97 is provided on the frame 11 for the travel seat 96 to pass through and act as a guide. The travel seat 96 is fitted onto the guide shaft 97 and slides along the guide shaft 97. The length direction of the guide shaft 97 is consistent with the movement direction of the travel seat 96, thereby providing precise guidance for the movement of the travel seat 96.

[0047] In actual operation, the mold base drive first drives the upper mold base 22 to descend, working together with the lower mold base 21 to stamp the shoe support material into a shoe support with a concave heel structure. Then, the upper mold base 22 rises and resets, and the ejector drive drives the ejector suction cup 31 to move above the formed shoe support. The first cylinder 91 drives the ejector suction cup 31 to descend and applies negative pressure to lift the shoe support. Then, the first cylinder 91 drives the ejector suction cup 31 to rise, and the ejector drive continues to drive the ejector suction cup 31 to move above the stop bar 51 in the unloading area 41. After reaching the predetermined position, the first cylinder 91 again drives the ejector suction cup 31 to descend to a position close to the stop bar 51, and then releases the shoe support. The shoe support falls under gravity, its front end contacting and being supported by the stop bar 51, while the rear end continues to fall until the entire shoe support is tilted with the front end higher than the rear end, at which point the concave heel structure at the rear end of the shoe support faces upwards. After the first shoe support lands in the material feeding area 41 in this posture, its heel concave structure becomes a positioning cavity 61. When the second shoe support lands in the same way, its front end is also supported by the stop bar 51, and its rear end falls precisely into the positioning cavity 61 of the first shoe support, forming a stable interlocking stack of the two shoe supports. As the number of shoe supports increases, all shoe supports are stacked in sequence to form a neat stack of shoe supports. When the number of stacks reaches a preset value, the discharge drive unit drives the lever 32 to move to the rear of the stacked shoe supports, and the second cylinder 92 drives the lever 32 to descend to a position that contacts the outer heel of the last shoe support. Then, the discharge drive unit continues to drive the lever 32 to move towards the material feeding collection area 82. At this time, the stop bar 51 will retract to avoid interference with the lever 32. The lever 32 pushes the entire set of shoe supports from the material feeding area 41 into the material feeding collection area 82. After the push is completed, the lever 32 rises and resets under the drive of the second cylinder 92. The discharge drive unit drives the lever 32 back to the initial position, waiting for the next push action. Throughout the process, since the height of the stop lever 51 can be precisely adjusted through the adjustment hole 421 or the linear actuator 52, it can be ensured that shoe trees of different sizes can obtain the best tilt angle and stacking posture, thereby realizing the automatic, orderly, and stable stacking and placement of shoe trees, effectively reducing manual handling and improving the automation level and production efficiency of the production line. It should be noted that the shoe tree machine integrating material picking and stacking provided in this application is not only suitable for shoe trees with heel structures, but also for shoe trees without heel structures. When the shoe trees produced are ordinary shoe trees without heels, there is no need to use the tilting stacking method. At this time, the stop lever 51 can be retracted from the feeding area 41 (for example, by driving the stop lever 51 out of the feeding area 41 through the linear actuator 52), so that the feeding area 41 forms a flat dropping space. After the discharge suction cup 31 moves above the unloading area 41, it directly releases the shoe support horizontally. The shoe support can then be placed horizontally and stably at the bottom of the unloading area 41 or on top of the already stacked shoe supports, thus achieving conventional vertical stacking.

[0048] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
