Description

Technical Field

[0001] This invention relates to the field of window manufacturing, and more particularly to a window and door production line and manufacturing method. Background Technology

[0002] Doors and windows generally consist of sashes and frames. Therefore, the production of doors and windows involves the production, processing and assembly of sashes and frames. The production and processing of sashes and frames generally includes steps such as machining, assembly, bonding, and installation of hardware. Finally, the corresponding frames and sashes are assembled to form finished products. During the assembly process, the sash is first installed on the frame by hinges using a CNC vertical hanging sash adjustment frame. The gap between the two after installation is checked to ensure it is up to standard and then adjusted.

[0003] In the existing technology, the door and window production line includes a frame production line, a sash production line and a frame-sash assembly line. The frame and sash are manufactured on their respective production lines and then shipped out for assembly. Because the frame is larger in size and requires more holes and slots to be machined and more hardware to be installed, the overall processing efficiency of the frame is lower than that of the sash. Therefore, a sash temporary storage area is set up at the unloading end of the sash production line so that they can be assembled together after the matching frames are shipped out.

[0004] The above technical solutions require manual transfer of window sashes and frames from the sash storage area and frame production line to the assembly area for assembly, resulting in long logistics distances and long distances for operators to pick up and drop materials, leading to low production efficiency. Summary of the Invention

[0005] To address the technical problem of low assembly efficiency in the prior art, this invention provides a door and window production line and production method that can improve the transfer efficiency of window frames and sashes, thereby greatly improving the production efficiency of windows.

[0006] To solve the above-mentioned technical problems, in a first aspect, the present invention provides a door and window production line, including a sash storage system and a frame storage system, wherein the sash storage system and the frame storage system are parallel, and both the sash storage system and the frame storage system include a first transport device, the first transport device including a first track and a first transport vehicle, the first transport vehicle being movable along the first track, and a first support frame being rotatably mounted on the first transport vehicle; it also includes a first turnover device, the first turnover device including a second track and a second transport vehicle, the second transport vehicle being movable along the second track, the length direction of the second track being perpendicular to the length direction of the first track, and the second track being located at the discharge end of the sash storage system and the frame storage system; it also includes an assembly line, the loading end of the assembly line being located on one side of the second track. By setting up the first turnover device, the frames and sashes can be automatically unloaded to the loading end of the assembly line instead of manually, which shortens the material transportation distance and helps to improve production efficiency. At the same time, the rotatable support frame can change the material transportation direction, so that the sashes and frames can be unloaded from the warehouse using a single transport vehicle, which improves the utilization rate of the transport vehicle, reduces the need for the deployment of corresponding transportation devices, and saves costs and space.

[0007] Furthermore, the transport vehicle is equipped with a drive assembly, which includes a drive motor and a drive gear connected to each other. The drive gear meshes with a gear ring, and the gear ring is connected to the lower part of the support frame.

[0008] Furthermore, at least two transport vehicles are provided. Using multiple transport vehicles improves the efficiency of outbound shipments of frames and panels.

[0009] Furthermore, the bottom of the support frame one is provided with a conveyor belt one, the conveyor belt one includes a conveyor motor one, the transport vehicle two includes a support frame two, the bottom of the support frame two is provided with a conveyor belt two, the conveyor belt two includes a conveyor motor two.

[0010] Furthermore, it also includes at least two parallel hanging fan debugging devices, which are located between the first turnover device and the loading end of the assembly line, along the material movement direction. Each hanging fan debugging device includes a fan storage rack, a hanging fan debugging rack, and a conveying device in sequence. A frame storage rack is also provided on one side of the fan storage rack. The frame storage rack and the fan storage rack are arranged side by side on one side of the second track. The frame storage rack and the hanging fan debugging rack are arranged side by side. The second transport vehicle can transport the frames to the frame storage rack and the second transport vehicle can transport the fans to the fan storage rack.

[0011] Furthermore, the fan storage rack, the frame storage rack, the hanging fan debugging rack, and the conveying device all include a storage rack, and a conveyor belt three is provided at the lower part of the storage rack, and the conveyor belt three includes a conveyor motor three.

[0012] Furthermore, the conveying device includes a conveying frame with a base plate at its lower part, the base plate being placed on the ground. A second drive motor and a second drive gear are connected to the base plate. The second drive gear meshes with a second gear ring, which is rotatably mounted on the base plate and connected to the conveying frame. By making the conveying device rotatable, multiple hanging fan adjustment devices are prevented from forming a closed area, thus avoiding inconvenience for personnel and materials to enter and exit.

[0013] Furthermore, the assembly line includes a loading and conveying device, which comprises a parallelly arranged temporary storage rack and a conveying device three. The temporary storage rack is located at the unloading end of multiple hanging fan debugging devices. The conveying device can transport the frame after hanging the fan to the corresponding support frame of the temporary storage rack. The conveying device three includes a track three and a transport vehicle three. The transport vehicle three can move along the track three. The transport vehicle three is equipped with a support frame three, and the bottom of the support frame three is equipped with a conveyor belt three, which includes a conveyor motor three. By setting up the loading and conveying device, the automatic conveying and storage of the frame after hanging the fan is achieved, eliminating the need for manual handling.

[0014] Furthermore, the assembly line also includes at least two assembly workbenches located at the unloading end of the feeding and conveying device. Multiple assembly workbenches are arranged along the length of track three. A feeding device is provided between the assembly workbenches and track three. The feeding device includes a support frame, one end of which is rotatably equipped with a tilting frame. A tilting drive is provided between the tilting frame and the support frame, and a conveyor belt is provided at the bottom of the tilting frame. The feeding device automatically tilts the frame behind the hanging fan to a horizontal position, replacing manual tilting.

[0015] Secondly, the present invention provides a door and window production method. Using the above-mentioned door and window production line, when the first transport vehicle moves to the vicinity of the first turnover device, the first support frame rotates 90° and the sash or frame is transferred to the second transport vehicle. The second transport vehicle transfers the sash or frame to the corresponding hanging sash debugging device. The frame after hanging the sash is transferred by the third transport vehicle to the feeding device or temporarily stored in the temporary storage rack.

[0016] As can be seen from the above technical solutions, the present invention has the following advantages:

[0017] This invention provides a door and window production line and production method. By setting up a first turnover device, the frame and sash can be automatically unloaded to the loading end of the assembly line, replacing manual labor. This shortens the material transportation distance and improves production efficiency. At the same time, the rotatable support frame can change the material transportation direction, allowing the sash and frame to share a single transport vehicle, improving the utilization rate of the transport vehicle and reducing the need for additional transport devices, thus saving costs and space. By making the conveying device rotatable, multiple sash hanging and debugging devices are prevented from forming a closed area, which would be inconvenient for personnel and materials to enter and exit. The loading and transporting device enables the automatic conveying and storage of the frame after the sash is hung, eliminating the need for manual handling. The loading device automatically flips the frame after the sash is hung to a horizontal position, replacing manual flipping. Attached Figure Description

[0028] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1

[0030] like Figures 1 to 4 , Figure 6 and Figure 7As shown, this specific embodiment provides a door and window production line, including a sash storage system 27 and a frame storage system. In this specific embodiment, two frame storage systems are arranged in parallel, including frame storage system one 3 and frame storage system two 11. The sash storage system 27 is parallel to frame storage system one 3 and located between frame storage system one 3 and frame storage system two 11. The sash storage system 27, frame storage system one 3, and frame storage system two 11 all include a transport device one. The transport device one includes a track one 14 and a transport vehicle one 26. The transport vehicle one 26 can move along the track one 14. The transport vehicle one 26 includes a base frame 13. A drive assembly and a support frame one 12 are arranged on the base frame 13. The drive assembly can drive the support frame one 12 to rotate. Specifically, the drive assembly includes a drive motor one 23 and a drive gear one 22 connected to each other. The drive motor one 23 and the drive gear one 22 are mounted on a mounting plate 21, which is set on the base frame 13. The gear ring 15 is mounted on the mounting plate 21 via bearings. The drive gear 22 meshes with the gear ring 15, and the gear ring 15 is connected to the connecting plate 18 at the lower part of the support frame 12. The system also includes a first turnover device, which comprises a second track 4 and a second transport vehicle 28. The second transport vehicle 28 can move along the second track 4. The length direction of the second track 4 is perpendicular to the length direction of the first track 14, and the second track 4 is located at the discharge end of the fan storage system 27. The system also includes an assembly line, the loading end of which is located on one side of the second track 4. Furthermore, the system includes at least two hanging fan debugging devices 5, located between the first turnover device and the loading end of the assembly line. Multiple hanging fan debugging devices 5 are arranged along the length direction of the second track 4, and are located on one side of the second track 4. In this specific embodiment, four hanging fan debugging devices 5 are arranged in parallel. The second transport vehicle 28 can transfer fans or frames from the first transport vehicle 26 to the loading end of the hanging fan debugging device 5. By cooperating with the rotating transport vehicle 26 of the support frame 12 and the first turnover device, the direction of material transportation is adjusted, which provides a prerequisite for the automatic transportation of materials to the assembly line. At the same time, it also realizes that the transfer of frames and fans can share a turnover device, eliminating the need for the installation of conveying devices at the discharge end of the frame storage system and the fan storage system, improving the utilization rate of the transport vehicle 28, and saving costs and space.

[0031] like Figure 1 As shown, in order to improve the efficiency of the outbound of frames or fans, at least two transport vehicles 28 are provided. In this specific embodiment, two transport vehicles 28 are provided.

[0032] like Figure 2As shown, in order to improve transportation efficiency, in this specific embodiment, a conveyor belt 17 is provided at the bottom of the support frame 12. The conveyor belt 17 includes a conveyor motor 16. The transport vehicle 28 includes a support frame 2. The bottom of the support frame 2 is provided with a conveyor belt 2. The conveyor belt 2 includes a conveyor motor 2. Both the conveyor belt 17 and the conveyor belt 2 can achieve autonomous transportation. When it is necessary to transfer the frame or the fan, the conveyor belt 17 and the conveyor belt 2 can be aligned and rotated in the same direction to achieve transportation.

[0033] like Figure 8 As shown, in this specific embodiment, along the material movement direction, the hanging fan adjustment device 5 sequentially includes a fan storage rack 10, a hanging fan adjustment rack 32, and a conveying device 29. A frame storage rack 31 is also provided on one side of the fan storage rack 10. The frame storage rack 31 and the fan storage rack 10 are arranged side by side on one side of the second track 4. The frame storage rack 31 and the hanging fan adjustment rack 32 are arranged side by side. The second transport vehicle 28 can transport the frames to the frame storage rack 31 and the fans to the fan storage rack 10. Specifically, the fan storage rack 10, the frame storage rack 31, the hanging fan adjustment rack 32, and the conveying device 29 all include storage racks. A conveyor belt 3 is provided at the bottom of the storage rack. The conveyor belt 3 includes a conveyor motor 3. The storage racks are all fixed to the ground by mounting brackets. Since the number of fans in a set of windows is more than the number of frames, in this specific embodiment, the fan storage rack 10 includes four sub-racks that can accommodate four fans.

[0034] like Figure 5 As shown in this specific embodiment, four hanging fan debugging devices 5 are arranged side by side, and a first turnover device and an assembly line are set at both ends, forming a closed area, which makes it difficult to transport materials and allow personnel to enter and exit. To avoid this technical problem, the conveying device 29 includes a conveying frame 20, and a base plate 30 is set at the bottom of the conveying frame 20. The base plate 30 is set on the ground, and a second drive motor and a second drive gear are connected to the base plate 30. The second drive gear meshes with a second gear ring, which is rotatably set on the base plate 30 and connected to the conveying frame 20. The second drive motor can rotate the conveying frame 20 by a certain angle, so that the discharge end of the hanging fan debugging device 5 is in the open state, which meets the requirements of material transportation and personnel entry and exit.

[0035] like Figure 1As shown, in order to automatically transport the adjusted fan frame to the next process, in this specific embodiment, the assembly line includes a feeding and conveying device. The feeding and conveying device includes a parallel temporary storage rack 6 and a conveying device 7. The temporary storage rack 6 is also parallel to the track 4. The temporary storage rack 6 is located at the unloading end of multiple fan adjustment devices 5. The conveying device 29 can transport the fan frame to the corresponding support frame of the temporary storage rack 6. The conveying device 29 includes a conveyor frame, a conveyor belt 4 is provided at the bottom of the conveyor frame, and a motor 4 is provided on the conveyor belt 4. The temporary storage rack 6 includes multiple support frames. The conveyor belt 4 can transfer the frame behind the hanging fan to the corresponding support frame. The transport device 3 7 includes the track 3 and the transport vehicle 3. The transport vehicle 3 can move along the track 3. The transport vehicle 3 is equipped with a support frame 3. The bottom of the support frame 3 is equipped with a conveyor belt 3. The conveyor belt 3 includes a conveyor motor 3. The transport vehicle 3 can transfer the frame behind the hanging fan on the support frame to the next process. Alternatively, since the assembly cycle is slower than the hanging fan debugging, in order to ensure the continuous and smooth feeding of the conveyor device 29, the transport vehicle 3 can transfer the frame behind the hanging fan on the support frame to the empty support frame of the temporary storage rack 6 for temporary storage.

[0036] like Figure 1 As shown, the assembly production line also includes at least two assembly workbenches 9. The assembly workbenches 9 are located at the unloading end of the transport device 3 7. Multiple assembly workbenches 9 are arranged along the length of the track 3. In this specific embodiment, two assembly workbenches 9 are provided. A loading device 8 is provided between the loading end of the assembly workbench 9 and the track 3. Since the frame after hanging the fan needs to be in a horizontal state during assembly, but the frame after hanging the fan is in a vertical state during transportation, in order to replace manual flipping, the loading device 8 includes a support bracket. A flipping frame is rotatably provided at one end of the support bracket. A flipping drive is provided between the flipping frame and the support bracket. A conveyor belt 4 is provided at the bottom of the flipping frame.

[0037] In this specific embodiment, the frame storage system 3 and the second frame storage system 11 have the same structure, both including a first transport device and a first storage device 25. The structure of the first transport device (not mentioned in this specific embodiment) and the structure of the first storage device 25 are the same as those of the transport device and storage device in the intelligent frame storage system published in patent CN 115489955 A, and therefore will not be described in detail. The frame storage system 3 and the second frame storage system 11 are symmetrically arranged about the fan storage system 27. The structure of the fan storage system 27 (not mentioned in this specific embodiment) is basically the same as that of the intelligent frame storage system published in CN 115489955 A, and therefore will not be described in detail. The feeding device 8 in this specific embodiment has the same structure as the storage device, transport device, and feeding device in the intelligent frame storage system published in CN 115489955 A, where the flipping frame in the feeding device 8 is equivalent to the conveyor frame in the intelligent frame storage system, and therefore its detailed structure will not be described in detail here. The first turnover device is the same as that in CN 115489955 A. The transport device in the intelligent frame storage system has the same structure, so its structure will not be described in detail; the hanging fan debugging frame 32 is a finished product that can be purchased on the market, so its structure will not be described in detail.

[0038] like Figure 1 As shown, this specific embodiment also includes a fan production line 2 and two frame production lines 1. The fan production line 2 is located at the feeding end of the fan storage system 27, and the two frame production lines 1 are located at the feeding ends of the frame storage system 1 3 and the frame storage system 2 11, respectively. The fan storage system 27, the frame storage system 1 3 and the frame storage system 2 11 can all be used for fan and frame gel curing. Specific Implementation Method Two

[0040] This specific embodiment provides a door and window production method, using the door and window production line of Specific Embodiment 1. When the frames in frame storage system 1 (3) and frame storage system 2 (11) meet the outbound conditions, the corresponding transport vehicle 26 transports the frames out of the warehouse. At the same time, the sashes that are part of the same frame are taken out of the sash storage system 27 by the corresponding transport vehicle 26. When the transport vehicle 26 moves close to the first turnover device, the support frame 12 rotates 90°, and the transport vehicle 28 moves into position to receive the material. The sashes or frames are transferred to the transport vehicle 28. The sashes or frames are transferred to the sash storage rack 10 and frame storage rack 31 by the transport vehicle 28. The operator controls the sash hanging and debugging rack to transfer the frames to the sash hanging and debugging rack 32. At the same time, the sashes are manually moved for hanging, inspection, and adjustment. After adjustment, the frames with sashes are transferred from the sash hanging and debugging rack 32 to the temporary storage rack 6 via the conveying device 29. The frames with sashes are then transferred by the transport vehicle 3 to the loading device 8 or temporarily stored in the temporary storage rack 6.

[0041] When materials need to be conveyed to the hanging fan test frame, the four conveying devices 29 rotate at a set angle to form a conveying channel.

[0042] When multiple feeding devices 8 have materials, the transport vehicle 3 moves the frame behind the hanging fan to the temporary storage rack 6 on the support frame that is not opposite to the corresponding conveying device.

[0043] As can be seen from the above specific embodiments, the present invention has the following beneficial effects:

[0044] 1. By setting up the first turnover device, the frames and sashes can be automatically discharged to the loading end of the assembly line instead of manually, which shortens the material transportation distance and helps to improve production efficiency. At the same time, through the cooperation of the rotating transport vehicle 26 of the support frame 12 and the first turnover device, the sashes and frames can be discharged from the warehouse using a single transport vehicle 28, which improves the utilization rate of transport vehicle 28, reduces the layout of corresponding transport devices, and saves costs and space.

[0045] 2. By making the conveyor device 29 rotatable, the multiple hanging fan debugging devices 5 are prevented from forming a closed area, which would be inconvenient for personnel and materials to enter and exit;

[0046] 3. By setting up a feeding and transportation device, the frame after the hanging fan is automatically transported and temporarily stored, eliminating the need for manual handling;

[0047] 4. The feeding device 8 automatically flips the frame behind the hanging fan to a horizontal position, replacing manual flipping.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
