Description

Technical Field

[0001] This invention relates to the field of shoe cover technology, and in particular to an automatic demolding method for shoe covers. Background Technology

[0002] Shoe covers, also known as shoe covers, are common waterproof and stain-resistant protective products used to prevent shoes from getting wet in rainy weather. Shoe covers can be molded from shoe molds, and after molding, the shoe covers need to be manually removed from the molds. This manual process is inefficient and costly, hindering large-scale production. Furthermore, the molds are still hot when the shoe covers are removed, which can cause burns to the hands of workers during prolonged work. Summary of the Invention

[0003] The present invention provides an automatic demolding method for shoe covers, which solves the problems of low efficiency and high labor costs in the process of shoe covers being immersed and molded in a shoe mold, and the need for manual removal of the shoe covers from the mold after molding, which is not conducive to the large-scale production of shoe covers. In addition, the mold is still at a high temperature when the shoe cover is removed from the mold, which can cause burns to the hands of workers during prolonged work.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An automatic demolding method for shoe covers, comprising:

[0006] A shoe mold and a shoe cover formed and adhered to the outer surface of the shoe mold are provided, the shoe cover having a ribbed opening;

[0007] The nozzle of the compressed gas blowing device is arranged along the shoe cover opening on the shoe mold, so that the nozzle blows air through the gap between the shoe cover opening and the shoe mold. The compressed gas enters the contact surface between the shoe cover and the shoe mold through the gap. Since the shoe cover is elastic, it bulges and deforms under the action of the compressed gas, causing the contact surfaces between the shoe cover and the shoe mold to separate from each other.

[0008] In one embodiment, after the step of separating the surfaces in contact between the shoe cover and the shoe mold is completed, the nozzle of the compressed gas blowing device is moved along the axis of the shoe mold, so that the compressed gas blown out by the nozzle drives the shoe cover to detach from the shoe mold.

[0009] In one embodiment, while the nozzle of the compressed gas blowing device is moved along the axis of the shoe mold, the nozzle of the compressed gas blowing device is also moved in rhythm with the detachment of the shoe cover opening as the shoe cover opening falls / detaches, so that the compressed gas can be continuously blown into the gap between the shoe cover and the shoe mold.

[0010] In one embodiment, the step of blowing compressed gas through the nozzle of the gas blowing device along the gap between the shoe cover opening and the shoe mold specifically involves placing two sets of nozzles on opposite sides of the shoe mold and blowing compressed gas along the gap between the shoe cover opening and the shoe mold.

[0011] In one embodiment, after the steps of separating the surfaces in contact between the shoe cover and the shoe mold are completed, a non-corrosive liquid is injected into the shoe cover through the gap between the crease and the shoe mold. The liquid flows into the toe area of ​​the shoe cover, causing the shoe cover to detach from the shoe mold under the gravity of the injected liquid.

[0012] In one embodiment, the step of blowing air through the nozzle of the compressed gas blowing device along the gap between the rib and the shoe mold specifically involves: placing two sets of nozzles on opposite sides of the shoe mold and blowing air along the gap between the rib and the shoe mold; and simultaneously, the step of injecting non-corrosive liquid into the shoe cover through the gap between the rib and the shoe mold specifically involves: injecting the liquid into the shoe cover through the gap between the rib and the shoe mold on opposite sides of the shoe mold.

[0013] In one embodiment, after completing the step of separating the surfaces in contact between the shoe cover and the shoe mold, the automatic demolding method further includes the following step: inserting a push rod into the shoe cover through the gap between the ribbing and the shoe mold, with the push rod located at the heel and moving from the ribbing toward the side where the sole is located, so that the push rod drives the shoe cover to detach from the shoe mold.

[0014] In one embodiment, after the step of separating the surfaces in contact between the shoe cover and the shoe mold is completed, the automatic demolding method further includes the following steps: grabbing the shoe cover near the heel of the shoe with a first gripper, and after grabbing, moving the first gripper along the central axis of the shoe mold from the heel toward the toe of the shoe to drive the shoe cover to detach from the shoe mold.

[0015] In one embodiment, while the first gripper grips the shoe cover near the heel of the shoe, the automatic demolding method further includes the following steps: the second gripper grips the shoe cover near the toe of the shoe, and after gripping, the second gripper moves with the first gripper from the heel toward the toe of the shoe, so as to detach the shoe cover from the shoe mold.

[0016] In one embodiment, after the step of separating the surfaces in contact between the shoe cover and the shoe mold is completed, the automatic demolding method further includes the following steps: grabbing the toe part of the shoe cover with a first gripper, and after grabbing, moving the first gripper from the heel toward the side where the toe is located, so as to drive the shoe cover to detach from the shoe mold.

[0017] The automatic demolding method for shoe covers in this embodiment of the invention uses an air blowing method. The nozzle of the compressed gas blowing device can continuously blow air along the gap between the rib and the shoe mold, so that the gas has sufficient pressure to directly drive the shoe cover off the surface of the shoe mold, thus realizing the removal of the shoe cover. In this method, the machine has a high degree of automation, which reduces the use of personnel and effectively improves production efficiency. The compressed gas blowing device can work for a long time, which helps to reduce costs. At the same time, it can also reduce human intervention, so as to avoid the mold being still at a high temperature when the shoe cover is removed from the shoe mold, which could cause burns to the hands of people working for a long time.

[0023] First Embodiment

[0024] refer to Figure 1 This invention provides an automatic demolding method for shoe covers, comprising the following steps:

[0025] Step S10: Provide a shoe mold and a shoe cover that is applied to the outer surface of the shoe mold, the shoe cover having a ribbed opening;

[0026] In step S20, the nozzle of the compressed gas blowing device is arranged along the shoe cover opening on the shoe mold, so that the nozzle blows compressed gas through the gap between the shoe cover opening and the shoe mold. The compressed gas enters the contact surface between the shoe cover and the shoe mold through the gap. Since the shoe cover is elastic, it bulges and deforms under the action of the compressed gas, so that the contact surfaces between the shoe cover and the shoe mold separate from each other.

[0027] Specifically, in this embodiment, the edges of the rib opening are neat, which facilitates the blowing of compressed gas between the air nozzle and the shoe mold. It is understood that in other embodiments, the edges of the rib opening may not be neat.

[0028] In the automatic demolding method of this invention, the shoe cover is a latex shoe body formed by impregnating a shoe mold with liquid latex. The latex material of the shoe cover has good elasticity and toughness. The shoe cover, also known as a shoe cover, can be placed over the outer surface of the shoe in rainy weather to prevent the shoe from getting wet, thus facilitating the user's travel. The shoe cover can also be used in industrial environments to protect shoes from dust.

[0029] Meanwhile, by using the blowing method, the nozzle of the compressed gas blowing equipment can continuously blow air along the gap between the shoe mold and the shoe cover, so that the gas has sufficient pressure to directly lift the shoe cover off the surface of the shoe mold, thus achieving the removal of the shoe cover. In this method, the machine has a high degree of automation, which reduces the use of personnel and effectively improves production efficiency. The compressed gas blowing equipment can work for a long time, which helps to reduce costs. At the same time, it can also reduce human intervention, so as to avoid the mold being still at a high temperature when the shoe cover is removed from the shoe mold, which could cause burns to people's hands from prolonged work.

[0030] It should be noted that after step S20 is completed, i.e., after the surfaces of the shoe cover and the shoe mold that are in contact with each other are separated, the nozzle of the compressed gas blowing device moves along the axis of the shoe mold, causing the compressed gas blown by the compressed gas blowing device to detach the shoe cover from the shoe mold. During this process, the nozzle of the compressed gas blowing device moves along the axis of the shoe mold, that is, it moves from the heel towards the toe. This movement of the nozzle from the heel towards the toe can be driven by a drive structure, such as a drive motor, thereby enabling the nozzle to move back and forth along the side where the heel towards the toe is located. Furthermore, during this process, the nozzle moves slowly along the axis of the shoe mold. It can be understood that in other embodiments, the nozzle can also move rapidly along the axis of the shoe mold.

[0031] It is understood that in other embodiments, the step of moving the nozzle of the compressed gas blowing device along the direction from the heel towards the toe can be omitted. Simultaneously with the step of blowing air through the gap between the shoe cover and the shoe mold, the shoe cover can be manually detached from the shoe mold. Alternatively, while blowing air through the gap between the shoe cover and the shoe mold, the nozzle of the compressed gas blowing device can simply expel a sufficiently large amount of compressed gas.

[0032] It should be noted that while moving the nozzle of the compressed gas blowing device along the axis of the shoe mold, it also moves rhythmically along the shoe cover's opening as the shoe cover detaches from it. This ensures that compressed gas is continuously blown into the gap between the shoe cover and the shoe mold, thus detaching the shoe cover from the shoe mold. During this process, the downward movement of the compressed gas nozzle can be driven by a drive structure, such as a drive motor, thereby achieving an automated demolding process.

[0033] It is understood that in other embodiments, the step of moving the nozzle of the compressed gas blowing device along the rhythm of the shoe cover opening falling / loosening as the shoe cover opening falls / loosens can be omitted. In this case, the nozzle of the compressed gas blowing device can simply move along the axis of the shoe mold.

[0034] It should be noted that the step of blowing compressed gas through the gap between the shoe cover opening and the shoe mold is as follows: place two sets of nozzles on opposite sides of the shoe mold and blow compressed gas through the gap between the shoe cover opening and the shoe mold.

[0035] In the pneumatic demolding method of the present invention, the two sets of air nozzles can move back and forth along the direction from the heel towards the toe, and simultaneously, as the ribbing descends, they can move along the ribbing towards the sole, improving the demolding efficiency of the shoe cover. In other embodiments, the two sets of air nozzles are positioned on opposite sides of the shoe mold and blow air along the gap between the ribbing and the shoe mold; in this case, the two sets of air nozzles cannot move.

[0036] Second Embodiment

[0037] Continue to refer to Figure 1 This invention provides an automatic demolding method for shoe covers, comprising the following steps:

[0038] Step S10: Provide a shoe mold and a shoe cover that is applied to the outer surface of the shoe mold, the shoe cover having a ribbed opening;

[0039] In step S20, the nozzle of the compressed gas blowing device is arranged along the shoe cover opening on the shoe mold, so that the nozzle blows compressed gas through the gap between the shoe cover opening and the shoe mold. The compressed gas enters the contact surface between the shoe cover and the shoe mold through the gap. Since the shoe cover is elastic, it bulges and deforms under the action of the compressed gas, so that the contact surfaces between the shoe cover and the shoe mold separate from each other.

[0040] It should be noted that after completing step 20, i.e., after separating the contact surfaces between the shoe cover and the shoe mold, a non-corrosive liquid is injected into the shoe cover through the gap between the crease and the shoe mold, allowing the shoe cover to detach from the shoe mold under the force of gravity. Specifically, the liquid at this point has a certain pressure to facilitate the detachment of the shoe cover from the shoe mold under gravity and pressure, and the flow rate and pressure of the liquid can be determined by the user according to the actual situation.

[0041] It should be noted that the step of blowing compressed gas through the gap between the shoe cover opening and the shoe mold using the air nozzle device specifically involves: placing two sets of air nozzles on opposite sides of the shoe mold and blowing air along the gap between the shoe cover opening and the shoe mold; and simultaneously injecting liquid into the shoe cover through the gap between the opening and the shoe mold, specifically involving injecting a non-corrosive liquid into the shoe cover from opposite sides of the shoe mold through the gap between the opening and the shoe mold. Injecting the liquid into the shoe cover from opposite sides of the shoe mold improves the injection efficiency, allowing the shoe cover to be removed from the shoe cover more quickly. Specifically, the liquid here can be liquid water or other inert liquids.

[0042] It is understood that, in other embodiments, the step of blowing compressed gas through the gap between the shoe cover opening and the shoe mold using the air nozzle device specifically involves: blowing air through one air nozzle along the gap between the shoe cover opening and the shoe mold; and simultaneously injecting liquid into the shoe cover through the gap between the shoe cover opening and the shoe mold, specifically involves injecting liquid into the shoe cover from one side of the shoe mold through the gap between the shoe cover opening and the shoe mold. Alternatively, in other embodiments, the step of blowing compressed gas through the gap between the shoe cover opening and the shoe mold using the air nozzle device specifically involves: arranging multiple air nozzles at intervals around the circumference of the shoe mold and blowing air through the gap between the shoe cover opening and the shoe mold; and simultaneously injecting liquid into the shoe cover through the gap between the shoe cover opening and the shoe mold, specifically involves injecting liquid into the shoe cover along the circumference of the shoe mold through the gap between the shoe cover opening and the shoe mold.

[0043] Third Embodiment

[0044] Continue to refer to Figure 1 This invention provides an automatic demolding method for shoe covers, comprising the following steps:

[0045] Step S10: Provide a shoe mold and a shoe cover that is applied to the outer surface of the shoe mold, the shoe cover having a ribbed opening;

[0046] Step S20: Arrange the shoe cover opening on the shoe mold with the air nozzle of the compressed gas blowing device, so that the air nozzle blows compressed gas through the gap between the shoe cover opening and the shoe mold. The compressed gas enters the contact surface between the shoe cover and the shoe mold through the gap. The shoe cover is elastic, so the shoe cover bulges and deforms under the action of the compressed gas, causing the contact surfaces between the shoe cover and the shoe mold to separate.

[0047] It should be noted that after completing step S20, i.e., after separating the contacting surfaces between the shoe cover and the shoe mold, the automatic demolding method further includes the following step: inserting a push rod into the shoe cover through the gap between the ribbing and the shoe mold. The push rod is located at the heel and moves from the ribbing towards the sole, causing the push rod to detach the shoe cover from the shoe mold. During this process, the movement of the push rod can be accomplished by a drive structure, such as a drive motor, thereby achieving an automated shoe cover removal process.

[0048] It should be noted that the step of blowing compressed gas through the gap between the shoe cover opening and the shoe mold using the air nozzle device is as follows: Two air nozzles are positioned on opposite sides of the shoe mold, each blowing air along the gap between the shoe cover opening and the shoe mold; simultaneously, two push rods are inserted into the shoe cover through the gap between the shoe cover opening and the shoe mold. These push rods then detach the shoe cover from the shoe mold. The two push rods balance the force on opposite sides of the shoe cover, allowing it to detach more smoothly.

[0049] It is understood that, in other embodiments, the step of blowing compressed gas through the gap between the shoe cover opening and the shoe mold using the air nozzle device specifically involves: blowing air through the gap between the shoe cover opening and the shoe mold using an air nozzle; and simultaneously inserting a push rod into the shoe cover through the gap between the shoe cover opening and the shoe mold, specifically involves: inserting a push rod into the shoe cover through the gap between the shoe cover opening and the shoe mold to drive the shoe cover away from the shoe mold.

[0050] Fourth embodiment

[0051] Continue to refer to Figure 1 This invention provides an automatic demolding method for shoe covers, comprising the following steps:

[0052] Step S10: Provide a shoe mold and a shoe cover that is applied to the outer surface of the shoe mold, the shoe cover having a ribbed opening;

[0053] In step S20, the nozzle of the compressed gas blowing device is arranged along the shoe cover opening on the shoe mold, so that the nozzle blows compressed gas through the gap between the shoe cover opening and the shoe mold. The compressed gas enters the contact surface between the shoe cover and the shoe mold through the gap. Since the shoe cover is elastic, it bulges and deforms under the action of the compressed gas, so that the contact surfaces between the shoe cover and the shoe mold separate from each other.

[0054] It should be noted that after completing step S20, i.e., after separating the contacting surfaces between the shoe cover and the shoe mold, the automatic demolding method further includes the following steps: The first gripper grasps the shoe cover near the heel cuff, and after grasping, moves along the central axis of the shoe mold from the heel towards the toe, simulating the action of a person removing socks, thereby detaching the shoe cover from the shoe mold. The first gripper can grasp the shoe cover by clamping. During this process, the movement of the first gripper from the heel towards the toe can be driven by a drive structure, such as a drive motor, thus achieving an automated demolding process.

[0055] It should be noted that while the first gripper grips the shoe cover near the heel cuff, the automatic demolding method also includes the following steps: the second gripper grips the shoe cover near the toe, and after gripping, the second gripper moves along with the first gripper from the heel towards the toe, thereby detaching the shoe cover from the mold. The simultaneous action of the second and first grippers makes it easier for the shoe cover to detach from the mold. During this process, the movement of the second gripper from the heel towards the toe can be driven by a drive structure, such as a drive motor, thus achieving an automated demolding process.

[0056] It is understood that in other embodiments, the step of the first gripper gripping the shoe cover near the bottom of the heel can be omitted, and in this case, the step of the second gripper gripping the shoe cover near the toe can be retained. Alternatively, the step of the second gripper gripping the shoe cover near the toe can be omitted, and in this case, the step of the first gripper gripping the shoe cover near the bottom of the heel can be retained.

[0057] It should be noted that the step of blowing compressed gas through the gap between the shoe cover opening and the shoe mold using the air nozzle device is as follows: two sets of air nozzles are positioned on opposite sides of the shoe mold, and both sets blow air along the gap between the shoe cover opening and the shoe mold. The fact that both sets of air nozzles blow air along the gap between the opening and the shoe mold allows the contacting surfaces of the shoe cover and the shoe mold to separate fully, and also facilitates the first and second gripping components in lifting the shoe cover off the shoe mold.

[0058] It is understood that, in other embodiments, the step of blowing compressed gas through the gap between the shoe cover opening and the shoe mold using the nozzle device is specifically: blowing air through a nozzle along the gap between the shoe cover opening and the shoe mold.

[0059] Fifth embodiment

[0060] Continue to refer to Figure 1 This invention provides an automatic demolding method for shoe covers, comprising the following steps:

[0061] Step S10: Provide a shoe mold and a shoe cover that is applied to the outer surface of the shoe mold, the shoe cover having a ribbed opening;

[0062] In step S20, the nozzle of the compressed gas blowing device is arranged along the shoe cover opening on the shoe mold, so that the nozzle blows compressed gas through the gap between the shoe cover opening and the shoe mold. The compressed gas enters the contact surface between the shoe cover and the shoe mold through the gap. Since the shoe cover is elastic, it bulges and deforms under the action of the compressed gas, so that the contact surfaces between the shoe cover and the shoe mold separate from each other.

[0063] It should be noted that after completing step S20, i.e., after separating the contacting surfaces between the shoe cover and the shoe mold, the automatic demolding method further includes the following step: the first gripper grips the toe portion of the shoe cover, and after gripping, the first gripper moves from the heel towards the toe side to detach the shoe cover from the shoe mold. During this process, the movement of the first gripper from the heel towards the toe side can be driven by a drive structure, such as a drive motor, thereby achieving an automated demolding process.

[0064] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
