Description

Technical Field

[0001] This utility model relates to the field of shoemaking machinery, and in particular to an automatic memory device for the front and rear height positions of the inner support platform of a vamp machine and a vamp machine. Background Technology

[0002] Thanks to technological advancements, the shoemaking industry now widely utilizes shoemaking machines. Common shoe lasting machines are divided into fore-upper lasting machines and mid-to-rear lasting machines. The sequence is as follows: the fore-upper lasting machine lasts the toe section first, followed by the mid-to-rear lasting machine lasts the mid-to-rear section. The fore-upper lasting mechanism mainly includes a tightening mechanism, a gripper mechanism, and a fore-upper support mechanism. During lasting, the inner support platform mechanism first supports the shoe upper, making it fit tightly against the last. The fore-upper hand then inserts the shoe upper into the open gripper, which clamps the upper. The sweeping blade then completes the lasting action. However, since the inner support platform mechanism is fixed to the machine frame panel and cannot be moved, each time the last is changed, only the gripper mechanism can be adjusted to match the last size. Furthermore, when the last is placed on the flat inner support platform, the fore-upper last needs to be held down for initial clamping, which is inconvenient.

[0003] Therefore, some people have improved the structure of the inner support platform to make it movable. For example, patent document TWM271432 discloses a front lasting machine support platform adjustment mechanism, which uses a hydraulic cylinder to adjust the up and down movement of the inner support platform and is designed with a touch switch to limit the up and down movement position. However, since the lasting position of different shoe styles, sizes, or even left and right feet are not the same, the conventional inner support platform can only move up and down within the set stroke. Therefore, every time a different size or shoe style is changed, the position of the touch switch must be adjusted manually, which causes inconvenience to work and cannot increase production capacity. This is one of the defects. Furthermore, if the touch switch of the conventional inner support platform is not adjusted properly, it will still cause the inner support platform to rise too much and tear the fabric. This is the second defect.

[0004] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an automatic memory device for the front and rear height positions of the inner support platform of the front laster and the front laster. It mainly uses a position ruler to sense the front and rear height positions of the inner support platform and provides the information to the machine controller for memory. This allows the machine controller to control the inner support platform to the required position for different shoe styles or sizes based on the pre-memorized position, which can save the time of manual adjustment and greatly improve production capacity.

[0006] Secondly, the objective is to provide an automatic memory device for the front and rear height positions of the inner support platform of the front forming machine and the front forming machine itself. The device mainly uses a position ruler to memorize the front and rear height positions of the inner support platform, so that the machine controller can accurately control the position of the inner support platform to ensure the quality of forming and improve the yield.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An automatic memory device for the front and rear height positions of a support platform inside a front-end machine includes a support platform, a first drive member, a first position ruler, a second drive member, and a second position ruler. The first drive member is used to drive the support platform to move vertically, the first position ruler is used to sense the vertical position of the support platform and transmit the sensed position signal to the controller of the front-end machine for memory, and the second drive member is used to drive the support platform to move back and forth, the second position ruler is used to sense the back and forth position of the support platform and transmit the sensed position signal to the controller of the front-end machine for memory.

[0009] As a preferred embodiment, the support platform is mounted on a column, the column is mounted on a lifting platform, the lifting platform is mounted on a displacement platform, the first driving member is located inside the displacement platform to drive the displacement platform to move up and down, and the first position ruler has a fixed end and a movable end, the fixed end is connected to the displacement platform, and the movable end is connected to the lifting platform to sense the position of the lifting platform and transmit it to the controller for memory.

[0010] As a preferred embodiment, the second driving member is disposed on one side of the displacement stage to drive the displacement stage to move back and forth. The second driving member has a telescopic rod connected to the displacement stage, and the second position ruler has a fixed end and a movable end.

[0012] As a preferred embodiment, the second driving component is a hydraulic cylinder.

[0013] A front-end machine, employing an automatic memory device for the front and rear height positions of the inner support platform as described in any of the preceding claims.

[0014] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves the arrangement of a support platform, a first driving component, a first position ruler, a second driving component, and a second position ruler. The first driving component drives the support platform to move up and down, and the first position ruler senses the position of the support platform's vertical movement and transmits the sensed position signal to the controller of the upper-mounting machine for memory. The second driving component drives the support platform to move back and forth, and the second position ruler senses the position of the support platform's back and forth movement and transmits the sensed position signal to the controller of the upper-mounting machine for memory. Thus, the machine controller can control the inner support platform to the position required for different shoe styles or sizes according to the pre-memorized position, saving time for manual adjustment and greatly increasing production capacity. At the same time, the machine controller can precisely control the position of the inner support platform to ensure the quality of the upper assembly and improve the yield rate.

[0015] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0020] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] It should be noted that the front-vaulting machine is a common shoe-making machine, so the components such as the tightening mechanism, the gripper mechanism, and the front-vaulting support mechanism will not be described in detail. The main focus will be on the inner support platform 1.

[0023] An automatic memory device for the front and rear height positions of a front-end machine support platform includes a support platform 11, a first drive member 12, a first position ruler 13, a second drive member 14, and a second position ruler 15. The support platform 11 is mounted on a column 11, which is mounted on a lifting platform 112. The lifting platform 112 is mounted on a displacement platform 113. The first drive member 12 is located inside the displacement platform 113 to drive the displacement platform 112 to move up and down. In this embodiment, the first drive member 12 is a hydraulic cylinder. The first position ruler 13 has a fixed end 131 and a movable end 132. The fixed end 131 is connected to the displacement platform 113, and the movable end 132 is connected to the lifting platform 112 to sense the position of the lifting platform 112 and transmit it to the machine's controller (not shown in the figure).

[0024] The second driving member 14 is located on one side of the displacement stage 113 to drive the displacement stage 113 to move back and forth. In this embodiment, the second driving member 14 is a hydraulic cylinder with a telescopic rod 141 connected to the displacement stage 113. The second position ruler 15 has a fixed end 151 and a movable end 152. The fixed end 151 is connected to one end of the second driving member 14, and the movable end 132 is connected to the telescopic rod 141 to sense the position of the telescopic rod moving back and forth and transmit it to the controller of the machine.

[0025] During operation, as shown in Figures 2 and 3, when the first drive unit 12 drives the lifting platform 112 to rise and fall, the movable end 132 of the first position ruler 13 also rises and falls accordingly. When it rises and falls to the predetermined position, the first position ruler 13 will transmit the sensed position signal to the controller for memory, as the basis for the next rise and fall. Similarly, when the second drive unit 14 drives the displacement platform 113 to move back and forth, the movable end 152 of the second position ruler 15 will also move accordingly. When it moves back and forth to the predetermined position, the second position ruler 15 will transmit the sensed position signal to the controller for memory, as the basis for the next displacement. Utilizing the characteristic that the position ruler can sense the displacement, the memorized position data is input into the machine's controller. When the controller controls the inner support platform 1 to rise and fall, it automatically reaches the memorized position by using the sensing of the first position ruler 13. When the controller controls the inner support platform 1 to move back and forth, it automatically reaches the memorized position by using the sensing of the second position ruler 15. In this way, by utilizing the displacement sensing capability of the position ruler, the sensed position data is input into the machine controller for memory, and the inner support platform is controlled to the position required for different shoe styles or sizes. This can save time for manual adjustment and greatly increase production capacity. At the same time, the position ruler is used to memorize the front and rear height positions of the inner support platform, so that the machine controller can accurately control the position of the inner support platform to ensure the quality of the lasting and improve the yield rate.

[0026] Furthermore, a front-upper machine is provided, which utilizes an automatic memory device for the front-to-back height position of the inner support platform as described in any of the preceding claims. Front-upper machines are conventional shoe-making machinery, typically including components such as a tightening mechanism, a gripper mechanism, and a front-upper support mechanism. In this document, the tightening mechanism, gripper mechanism, and front-upper support mechanism will not be described in detail; the main focus is on the innovative design of the inner support platform. The application of this utility model's automatic memory device for the front-to-back height position of the inner support platform to the front-upper machine falls within the protection scope of this utility model.

[0027] The key design feature of this invention lies in its arrangement of a support platform, a first driving component, a first position ruler, a second driving component, and a second position ruler. The first driving component drives the support platform to move vertically, and the first position ruler senses the vertical position of the support platform and transmits the sensed position signal to the controller of the upper-mounting machine for memory. The second driving component drives the support platform to move back and forth, and the second position ruler senses the back and forth position of the support platform and transmits the sensed position signal to the controller of the upper-mounting machine for memory. This allows the machine controller to adjust the inner support platform to the required position for different shoe styles or sizes based on the pre-memorized position, saving time spent on manual adjustments and significantly increasing production capacity. Simultaneously, the machine controller can precisely control the position of the inner support platform to ensure the quality of the upper assembly and improve yield.

[0028] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
