Description

Technical Field

[0001] This invention relates to the field of escalator roller manufacturing technology, and particularly to an automatic trimming machine and trimming method for escalator rollers. Background Technology

[0002] Escalators are a type of escalator with circulating steps, and are fixed, electrically driven devices used to transport passengers upwards or downwards at an incline. Escalators are characterized by their large transport capacity, durability, and smooth operation, and are widely used in public places with high passenger traffic, such as department stores, supermarkets, airports, and subway stations. The rollers are a crucial component of escalators, and their quality and lifespan determine the overall quality and lifespan of the escalator.

[0003] Escalator rollers consist of rolling bearings, an aluminum core, and an outer ring. The outer ring is made of plastic and is injection molded in a mold during the escalator roller manufacturing process. However, during mass production of escalator rollers, the sidewalls of the produced rollers often have burrs, requiring trimming. Currently, most burr removal is done by hand using a scraper. Manual operation often results in operator injury due to difficulty in controlling the trimming force, and inconsistent trimming force affects the flatness of the escalator roller's sidewalls, thus impacting product quality and lifespan. Furthermore, manual trimming is inefficient in mass production. Summary of the Invention

[0006] The technical solution of this invention realizes the loading and unloading of the trimming machine through the feeding mechanism and the unloading mechanism.

[0009] As an optimization, the rotary mechanism includes: a drive assembly and a chuck; the chuck is rotatably connected to the drive assembly, and the drive assembly is fixedly mounted on the frame.

[0011] As an optimization, the drive assembly includes a drive motor and a rotary cylinder; the rotary cylinder is connected to the drive motor via a transmission belt, the drive motor is located on one side of the rotary cylinder, and the chuck is connected to the rotary cylinder.

[0012] The drive motor and rotary cylinder in the technical solution of the present invention can drive the chuck to rotate. At the same time, the rotary cylinder causes the escalator roller to expand and tighten when it is fitted onto the chuck. After the escalator roller is trimmed, it contracts to disengage from the chuck. This can achieve limit control of the escalator roller and realize the trimming operation of the escalator roller.

[0013] As an optimization, the drive assembly is provided with an ejection assembly, which includes an ejection cylinder and a push plate; one end of the push plate is connected to the ejection cylinder, and one side of the push plate is used to push the escalator roller onto the unloading mechanism after the escalator roller has finished trimming.

[0014] In the technical solution of this invention, the ejector cylinder and the push plate can eject the escalator roller from the clamp after the escalator roller trimming is completed.

The trimming is achieved by the rotational cooperation of the trimming tool and the escalator roller, and the overall structure is simple.

[0017] As an optimization, the trimming tool includes a first trimming head and a second trimming head, which are symmetrically arranged on the mounting base; a protrusion is provided at one end of the trimming tool near the wheel mechanism, and the protrusion cooperates with the escalator roller during trimming; the first trimming head, the second trimming head and the mounting base are U-shaped.

Detailed Implementation

[0033] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention. Content not described in detail below is common knowledge in the art.

[0034] See Figures 1 to 8 An automatic trimming machine for escalator rollers includes a frame 14, on which are provided: a feeding mechanism 1, which includes a feeding rail 2 connected to an external material tray and a support assembly 3 for transporting escalator rollers 13; a rotating wheel mechanism 4, which limits the escalator rollers 13 and drives them to rotate during trimming; a trimming part 5, which is located on one side of the rotating wheel mechanism 4 and trims both sides of the escalator rollers 13 during the operation of the trimming machine; a pushing wheel mechanism 6, which is located on one side of the frame 14 and pushes the escalator rollers 13 on the support assembly 3 onto the rotating wheel mechanism 4 during the operation of the trimming machine; and a unloading mechanism 7, which is located on one side of the rotating wheel mechanism 4 for transporting the trimmed escalator rollers 13.

[0035] When the trimming machine is working: the escalator roller 13 rolls onto the support assembly 3 via the feeding track 2. The support assembly 3 transports the escalator roller 13 to the coaxial position of the rotating mechanism 4. The pusher mechanism 6 pushes the escalator roller 13 onto the rotating mechanism 4, allowing the trimming part 5 to trim the escalator roller 13. The feeding mechanism 1 and the unloading mechanism 7 realize the loading and unloading of the trimming machine. The support assembly 3 can push the escalator roller 13 on the feeding mechanism 1 to the rotating mechanism 4, and use the trimming part 5 to perform trimming. This can realize the automated trimming of the escalator roller 13, meet the needs of mass production of escalator rollers, have high production efficiency, and the trimming force of the automated trimming machine is uniform, effectively improving the product quality of escalator rollers.

[0036] See Figures 4-7 In a specific embodiment, the support assembly 3 includes: a wheel frame 301 and a wheel frame moving cylinder 302 fixedly mounted on the frame 14; one end of the wheel frame moving cylinder 302 is connected to the wheel frame 301.

[0037] The escalator roller 13 rolls onto the wheel frame 301 of the support assembly 3 via the feeding mechanism 1. The moving cylinder drives the wheel frame 301 to move, so that the central axis of the escalator roller 13 corresponds to the central axis of the rotating wheel mechanism. The wheel frame 301 and the wheel frame moving cylinder 302 can support and limit the escalator roller 13 of the feeding mechanism 1 and transport it to the position corresponding to the rotating wheel mechanism 4. The overall structure is reasonably designed.

[0038] See Figure 4 and Figure 7 In a specific embodiment, the rotating wheel mechanism 4 includes: a drive component 401 and a chuck 402; the chuck 402 is rotatably connected to the drive component 401, and the drive component 401 is fixedly mounted on the frame 14.

[0039] The chuck 402 limits the movement of the escalator roller 13 and drives the roller to rotate. The escalator roller 13 is rotated by the drive assembly 401, and the chuck 402 can limit the movement of the roller 13, thereby enabling the trimming work of the trimming part 5 on the escalator roller 13 and achieving a better clamping effect on the roller 13.

[0040] See Figure 4 and Figure 7 In a specific embodiment, the drive assembly 401 includes a drive motor 411 and a rotary cylinder 421; the rotary cylinder 421 is connected to the drive motor 411 via a transmission belt 12, the drive motor 411 is located on one side of the rotary cylinder 421, and the chuck 402 is connected to the rotary cylinder 421.

[0041] The clamp 402 includes an expansion block and a rotating shaft; one end of the rotating shaft is tapered and engages with the expansion block; when the escalator roller 13 is mounted on the clamp 402, the rotary cylinder 421 pulls the rotating shaft to move inward, so that the tapered block at its end engages with the expansion block; after the escalator roller 13 has finished trimming, the rotary cylinder 421 pushes the rotating shaft to move outward, and the tapered block disengages from the expansion block.

[0042] See Figure 3 and Figure 4 In a specific embodiment, the drive assembly 401 is provided with an ejection assembly 8, which includes an ejection cylinder 801 and a push plate 802. One end of the push plate 802 is connected to the ejection cylinder 801, and one side of the push plate 802 is used to push the escalator roller 13 onto the unloading mechanism 7 after the escalator roller 13 has been trimmed.

[0043] After the escalator roller 13 is trimmed, the push cylinder 801 drives the push plate 802 to push the escalator roller 13 out of the chuck 402, so that the escalator roller 13 falls onto the unloading mechanism 7. The push cylinder 901 and the push plate 802 can push the escalator roller 13 out of the spring 402 chuck after the escalator roller 13 is trimmed. The automated control operation does not require manual handling of the escalator roller 13, and the overall work efficiency is high.

[0044] See Figure 3 , Figure 5 and Figure 6 In a specific embodiment, the trimming component 5 includes: a mounting base 501 and a trimming cutter 502; the trimming cutter 502 is fixedly mounted on the mounting base 501, and a receiving area 9 is provided on the trimming cutter 502. During trimming, one end of the escalator roller 13 is located in the receiving area 9 so that both sides of it contact the trimming cutter 502 for trimming.

[0045] The trimming tool 502 can perform trimming treatment on the side wall of the escalator roller 13 after injection molding, eliminating the traditional manual operation method. The trimming is achieved by the rotation of the trimming tool 502 and the escalator roller 13, and the overall structure is simple.

[0046] See Figure 8 In a specific embodiment, the trimming cutter 502 includes a first trimming cutter head 512 and a second trimming cutter head 522, which are symmetrically arranged on the mounting base 501. A protrusion 10 is provided at one end of the trimming cutter 502 near the wheel mechanism 4. The protrusion 10 cooperates with the escalator roller 13 during trimming. The first trimming cutter head 512, the second trimming cutter head 522 and the mounting base 501 are U-shaped.

[0047] The first trimming cutter head 512 and the second trimming cutter head 522 trim the edges on both sides of the escalator roller 13 respectively, effectively improving the trimming efficiency. The setting of the protrusion 10 makes the overall structure reasonable.

[0048] See Figure 8 In a specific embodiment, the frame 14 is provided with a first slide rail 1101 and a second slide rail 1102. The mounting base 501 is slidably mounted on the first slide rail 1101 by a driving device, and the first slide rail 1101 is slidably mounted on the second slide rail 1102. The first slide rail 1101 and the second slide rail 1102 are at a vertical angle.

[0049] The first slide rail 1101 and the second slide rail 1102 can adjust the position of the trimming part 5 without affecting the feeding, installation and unloading of the escalator roller 13, resulting in a high degree of automation.

[0050] See Figure 2 and Figure 4In a specific embodiment, the pusher mechanism 6 includes a pusher cylinder 601 and a pusher plate 602, with the pusher plate 602 rotatably connected to the cylinder rod of the pusher cylinder 601. The pusher cylinder 601 and the pusher plate 602 enable the escalator roller 13 on the support assembly 3 to be pushed onto the rotating wheel mechanism 4, so that the trimming part 5 can perform trimming work on the escalator roller 13.

[0051] An automatic trimming method is used for escalator rollers, which is implemented using an automatic trimming machine for escalator rollers. Specifically, the escalator roller 13 is transported to the wheel frame 301 of the support assembly 3 via the feeding rail 2. The escalator roller 13 is positioned on the wheel frame 301. The moving cylinder 302 pushes the wheel frame 301 to position the escalator roller 13 at the position corresponding to the rotating wheel mechanism 4. The pushing cylinder 601 pushes the push plate 602 so that one side of the push plate 602 acts on the escalator roller 13 and pushes the escalator roller 13 onto the rotating wheel mechanism 4. The drive motor 411 works and drives the rotating cylinder 421 through the transmission belt 12. The rotating cylinder 421 works to tighten the clamp 402 and limit the escalator roller 13. The escalator roller 13 rotates under the action of the rotating cylinder 421 and is trimmed by the trimming part 5. After trimming, the ejection assembly 8 acts on one side of the escalator roller 13 to disengage it from the clamp 202 and drop it to the unloading mechanism 7 for discharge.

[0052] This embodiment achieves automatic feeding and unloading of escalator rollers through a feeding mechanism and an unloading mechanism. Automatic trimming of the escalator rollers is achieved through a rotating wheel assembly and trimming parts. The overall structure is simple, and the automated operation can meet the needs of mass production of escalator rollers. It also eliminates traditional manual operation methods, effectively improving production efficiency and the trimming quality of the escalator rollers. Furthermore, this embodiment uses an automatic trimming method for escalator rollers, automating the feeding, limiting rotation, trimming, and unloading processes. This results in high production efficiency, good burr removal after injection molding of the escalator rollers, reduced manual operation requirements, and meets the needs of mass production of escalator rollers.

[0053] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
