Description

Technical Field

[0001] This utility model relates to the field of frame strip feeding device, specifically to a frame strip spring clip feeding device and a frame strip feeding line. Background Technology

[0002] Wrapped frame strips are strip-shaped materials used for decoration, sealing and reinforcing edges. They are commonly found in picture frames, furniture, doors and windows, and are made of materials such as solid wood, aluminum alloy, and PVC. They are both practical and aesthetically pleasing. Wrapped frame strips generally include the following types: (1) Solid wood wrapping: using pine, oak and other wood substrates, with wood veneer or PVC film on the surface. They are suitable for high-end decorative picture frames and furniture frames and have natural textures; (2) Aluminum alloy wrapping: using hot melt adhesive or wood grain film coating technology to achieve the same color effect as the board. They are mostly used for door and window sealing strips and elevator door frame trims; (3) MDF / PVC wrapping: using high-density board as the substrate, with paper or acrylic covering. It is low in cost and scratch-resistant. It is commonly used for picture frames and tabletop frames. Frequently used in: (1) Decoration: Customized home frame doors and wall panel edging to enhance the three-dimensionality of cabinet doors; L-shaped edging for photo frames and certificate frames to enhance structural stability; (2) Building materials: Door seam windproof sealing strips (PU or foam material), aluminum alloy door and window frame trim, which also have sound insulation and moisture-proof functions; (3) DIY crafts: Used for handmade covering of specimen display stands and dried flower photo frames, supporting personalized designs such as 45-degree splicing. In the existing technology, in order to improve output and efficiency, loading and unloading mechanisms are usually used to achieve high-speed production when designing the feeding equipment of the coating machine. Traditional feeding belt devices cause the belt to wear out quickly because the belt is constantly rubbing against the frame.

[0003] To address the above issues, there is an urgent need to invent a spring clip-type feeding device and a feeding line for the wrapping frame strips, in order to ensure stable and efficient operation during the feeding of the wrapping frame strips. Utility Model Content

It is simple to use, inexpensive and efficient, with a long stable operating cycle and significant economic benefits.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A clip-on feeding device for covering frame strips includes a conveying device and a clip-on feeding device. The clip-on feeding device is disposed above the conveying device and extends along the conveying direction of the conveying device. The clip-on feeding device is configured to periodically drop n covering frame strips vertically from top to bottom onto the conveying device. The conveying device is configured to convey the covering frame strips to a covering line. Wherein, n is a positive integer less than 5.

[0009] According to the above-described clip-on feeding device for covering frame strips, the clip-on feeding device includes a clip mechanism, a material support and release mechanism, and a pressing mechanism; wherein the clip mechanism is configured to hold the covering frame strips, the material support and release mechanism is configured to lift the covering frame strips and release them onto the conveying device at intervals, and the pressing mechanism is configured to press the covering frame strips onto the conveying device when the material support and release mechanism releases them.

[0010] According to the above-described frame strip spring clip feeding device, the spring clip mechanism includes a V-shaped discharge port with an opening at the lower end and two limiting rods connected to the lower opening of the V-shaped discharge port. The material feeding and discharging mechanism includes two symmetrically arranged pressure plates and a driving mechanism that drives the two pressure plates to move relative to each other or towards each other. The driving mechanism drives the movement of the pressure plates to realize the feeding or discharging of the covering frame strip. The pressure strip mechanism includes a lower pressure plate and a lower pressure driving mechanism, wherein the lower pressure driving mechanism drives the lower pressure plate to press down the covering frame strip.

[0011] According to the above-described frame strip spring clip feeding device, the spring clip mechanism and the material support and release mechanism are both mounted on the conveying device via an L-shaped fixing plate.

[0018] Compared with the prior art, the present invention has the following technical effects: This utility model provides a spring-loaded feeding device and a wrapping frame strip production line. It employs a spring-loaded mechanism and an adjustable material support and release mechanism to ensure the frame strips fall layer by layer onto the conveyor belt. Only 3-5 frame strips are on the feeding belt, reducing belt friction loss and allowing the pressure strip mechanism to provide sufficient power to the frame strips. Through analog signal interaction, the speeds of the feeding belt and the wrapping machine are synchronized, ensuring the feeding belt speed is always 10-20% higher than the wrapping machine speed (this can be adjusted via the analog signal interaction module according to actual conditions), meeting the continuous feeding requirements of the wrapping machine.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] In the description of this utility model, it should be understood that the use of terms such as "first" and "second" to define the components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this utility model.

[0025] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please see Figure 1-2 A clip-on feeding device for covering frame strips includes a conveying device 1 and a clip-on feeding device 2. The clip-on feeding device 2 is disposed on the upper part of the conveying device 1 and extends along the conveying direction of the conveying device 1. The clip-on feeding device 2 is configured to periodically drop n covering frame strips vertically from top to bottom onto the conveying device 1. The conveying device 1 is configured to convey the covering frame strips to a covering line. Wherein, n is a positive integer less than 5.

[0027] Specifically, the coating frame strip clip-type feeding device provided by this utility model combines a traditional conveying device and a clip-type feeding device. Its core advantages lie in its high efficiency, stability, space saving, and high degree of automation. It achieves extremely high feeding efficiency and continuity. Operators or robotic arms can load multiple coating frame strips into the clips at once, establishing a small material buffer zone. Furthermore, the device drops the frame strips from the clips in batches according to a preset rhythm (meaning that each batch consists of 5 or fewer coating frame strips), synchronized with the rhythm of the conveying device. This ensures that the feeding process perfectly matches the production rhythm of the downstream coating line, achieving continuous production of coating frame strips. The coating frame strips fall vertically with precise positioning: the frame strips fall vertically, and their trajectory is simple and controllable, making them less prone to rolling or jamming. This ensures that the frame strips land on the conveying device with a consistent posture, laying a solid foundation for subsequent precise coating. Simple structure and low failure rate: The "clip" and release mechanism are typically mechanical or simply pneumatically controlled, with a simple structure, reliable operation, and convenient maintenance, making them ideal for high-intensity use in industrial environments. Vertical utilization: Placing the feeding device above the conveyor fully utilizes vertical space, rather than occupying a large area horizontally; this is a significant advantage for production workshops with limited space. Compact layout: The entire device extends along the conveying direction, integrating seamlessly with the production line, ensuring a smooth flow and reducing the transfer distance and complexity of materials between processes. Through the ingenious combination of "clip buffer" and "vertical dropping," a compact spatial layout and efficient continuous operation are achieved, while ensuring the stability and reliability of the feeding process and good protection of materials. This is an excellent solution for improving the automation level and overall efficiency of the coating production line.

[0028] In one specific embodiment, the covering frame clip-type feeding device further includes a control system 3, which is configured to control the clip feeding device 2 to release material intermittently; wherein, the control system includes a PLC controller or a microcontroller.

[0029] Specifically, the control system can precisely control the timing and frequency of "intermittent feeding". It can ensure that the next frame bar is released only after the previous frame bar has been safely transported away by the conveyor device, perfectly avoiding collisions, overlaps or congestion between two frame bars at the landing point.

[0030] This directly ensures the continuity and stability of the production process, forming the foundation for efficient, unmanned automated production. Seamless integration and linkage with the entire production line are key advantages: PLCs are the standard control core in industrial automation. They can easily receive signals (such as "ready" or "feeding required") from other parts of the production line (e.g., conveyors, coating machines) and issue control commands (such as "start feeding"). This makes the feeding device no longer an isolated unit, but an organic component of the entire coating production line, achieving collaborative operation and greatly improving overall line efficiency. High flexibility and adjustability are also key advantages: By modifying the program within the PLC or microcontroller, the feeding interval can be easily adjusted to adapt to different production speeds, different frame specifications, or different process requirements. When changing product models or adjusting the production cycle, no complex mechanical adjustments are needed; only parameters need to be modified in the program, greatly improving the adaptability and production efficiency of the equipment. In this embodiment, a Siemens series PLC or a Mitsubishi series PLC can be used. For example, the PLC models include Siemens SINAMICS V90 series (S7-1200 series, such as CPU 1212C), Mitsubishi Electric MELSEC (FX series, such as FX3S-10MT / ESS or FX5S-30MT / ESS), Omron (CP1E series or CP1L series), etc.

[0031] In one specific embodiment, the control system 3 includes an analog signal interaction module 31, which is configured to control the conveying speed of the conveying device 1 and the wrapping speed of the wrapping line; wherein the conveying speed of the conveying device 1 is higher than the wrapping speed of the wrapping line.

[0032] Specifically, the conveyor speed (Vconvey) > the coating line speed (Vcoating). This inevitably leads to a tendency for the frame bars to "pil up" or "crowd together" between the two processes. This intentional speed difference creates a small, continuous, flexible buffer zone between the two devices. The frame bars are no longer rigidly pulled into the coating machine one by one, but rather slightly clustered before entering the coating machine, and smoothly pulled in by static friction between them. This completely eliminates rigid impacts, frame bar deformation, or end damage caused by the start-up or slight speed asynchrony of the two devices. It achieves the most ideal production mode—the downstream process drives the upstream process (pull production). The actual demand of the coating line directly determines the rate of material consumption, and the conveyor only needs to ensure that there is always material in front. This allows the entire system to automatically adjust the material flow according to the actual operating conditions of the coating machine (such as acceleration, deceleration, and constant speed) without the need for complex synchronization control algorithms. Since Vconvey > Vcoating, the frame bars will naturally "align" themselves before entering the coating machine. The traction mechanism of the coating machine will capture the leading frame bar and precisely align it with the machining center. Even if there is a slight deviation in the position of the frame strip falling from the conveyor, this speed difference can be automatically eliminated before entering the critical station. This ensures that each frame strip starts the wrapping process in a consistent and correct position, thereby significantly improving the wrapping quality and consistency of the product and reducing waste caused by misalignment. The system is more fault-tolerant and operates more stably. The small buffer formed by the speed difference can absorb short-term fluctuations within the system. It can tolerate short-term uneven intervals in the feeding of the conveyor; it can tolerate small speed fluctuations between the two drive systems. There is no need to use expensive and complex electronic gears or high-precision synchronization control cards to achieve absolute speed synchronization between the conveyor and the wrapping line. The control system only needs to send a constant speed setpoint (one slightly larger, one slightly smaller) to the inverters or drivers of the two devices through an analog signal interaction module, and the logic is very simple. This reduces the difficulty of program development, debugging time, and hardware performance requirements, thereby saving overall costs.

[0033] In one specific embodiment, the magazine feeding device 2 includes a magazine mechanism 21, a material support and release mechanism 22, and a pressing mechanism 23; wherein the magazine mechanism 21 is configured to hold the covering frame strip, the material support and release mechanism 22 is configured to lift the covering frame strip and release the covering frame strip onto the conveying device 1 at intervals, and the pressing mechanism 23 is configured to press the covering frame strip onto the conveying device 1 when the material support and release mechanism 22 releases the material.

[0034] Specifically, the combined design of this three-mechanism system (clamp mechanism 21, material feeding and unloading mechanism 22, and pressure bar mechanism 23) (storage, control, and release) breaks down a simple "material unloading" action into three controllable and reliable sub-steps. Through functional specialization and coordinated action, it transforms a potentially faulty and unreliable process into a robust, stable, and efficient automated core module. In short, its advantages can be summarized as: orderly storage, precise control, and reliable release, ultimately ensuring the flawless operation of the material loading process and providing a solid foundation for continuous, high-quality production in subsequent processes.

[0035] In one specific embodiment, the magazine mechanism 21 includes a V-shaped feed port 211 with an opening at the lower end and two limiting rods 212 connected to the lower opening of the V-shaped feed port; The material feeding and discharging mechanism 22 includes two symmetrically arranged pressure plates 221 and a drive mechanism 222 that drives the two pressure plates to move relative to each other or towards each other (exemplarily, the drive mechanism is a cylinder or a hydraulic cylinder, preferably a cylinder). The drive mechanism 222 drives the movement of the pressure plates 221 to realize the feeding or discharging of the covering frame strip. The pressing strip mechanism 23 includes a lower pressing plate 231 and a pressing drive mechanism 232 (exemplarily, the pressing drive mechanism can be a cylinder or a hydraulic cylinder, preferably a cylinder), the pressing drive mechanism 232 drives the lower pressing plate 231 to press down the covering frame strip.

[0036] Specifically, the V-shaped discharge port: The V-shaped structure naturally guides frame bars of different diameters or slight bends to the center position. This ensures that the material is in a predictable and consistent position before release, laying a solid foundation for subsequent stable discharge. The inclined V-shaped wall reduces the contact area and friction between the material and the silo wall, allowing the frame bars to slide down more smoothly under their own weight, avoiding the "bridging" or jamming phenomena that are prone to occur in rectangular silos. Two limit rods: These two limit rods are the core mechanical structure preventing "collapse".

[0037] Two symmetrical pressure plates and a drive mechanism: The two pressure plates move inward from both sides, firmly supporting the entire stack of frame strips. This symmetrical design ensures even force distribution, preventing the frame strips from tilting or jamming due to unilateral force. When material needs to be released, the drive mechanism causes the two pressure plates to move synchronously in opposite directions (while simultaneously retracting outward), and the frame strips fall through the gaps in the limit rods. All the frame strips above remain firmly supported by the pressure plates, completely eliminating the risk of multiple strips falling simultaneously. This "lift-release" mechanism is the most reliable of all magazine-type designs.

[0038] The pressure plate and pressure drive mechanism: Even if the frame bar is correctly released, it may get stuck on the limit bar due to friction, slight deformation, or center of gravity issues, and not fall completely onto the conveyor belt. The pressure plate mechanism, as a component that "ensures the execution of the action," actively presses down to ensure that the released frame bar completes 100% of the dropping action. Controlling the falling posture: Active pressure provides better control over the frame bar's falling trajectory and final posture than free fall, allowing it to land more smoothly and "correctly" on the conveyor, reducing bounce and deviation.

[0039] In one specific embodiment, both the magazine mechanism 21 and the material feeding and discharging mechanism 22 are mounted on the conveying device 1 via an L-shaped fixing plate 24. The L-shaped fixing plate 24 includes a vertical part and a horizontal part, and the L-shaped fixing plate 24 is inverted. The horizontal part is provided with an elongated through hole. The magazine mechanism 21 or the material feeding and discharging mechanism 22 is adjustablely mounted on the horizontal part via bolts, nuts and the elongated through hole.

[0040] Specifically, the magazine mechanism 21 and the material support and release mechanism 22 can be adjusted to accommodate different sizes and specifications of the covering frame strips by adjusting their relative positions in the horizontal section.

[0041] In one specific embodiment, the conveying device 1 includes a drive power source 11, a conveyor belt 12, and a frame 13. The drive power source 11 (exemplarily, the drive power source may be a servo motor) is disposed at one end of the frame 13, and the drive power source 11 is configured to drive the conveyor belt 12 to move.

[0042] In one specific embodiment, n is 3, 4, or 5.

[0043] A frame strip feeding device includes a frame strip spring clip feeding device.

[0044] In one specific embodiment, the wrapping frame line includes a wrapping frame spring clip feeding device and a wrapping line, and the control system simultaneously controls the wrapping frame spring clip feeding device and the wrapping line.

[0045] The above description is only an exemplary embodiment of the present utility model and is not intended to limit the present utility model.
