Description

Our Ref: 43970-19 CA National Phase of PCT/CN2021/111374 (FS2214P-CA-PCT) FULLY AUTOMATIC FRAMING MACHINE FOR ALUMINUM PROFILE
TECHNICAL FIELD
[0001] The present disclosure relates to the field of aluminum profile production, and in particular to a fully automatic framing machine for aluminum profiles.
BACKGROUND

[0002] During production of aluminum profiles, the aluminum profiles are layered and separated by parting strips to prevent surface damages and frictions between upper and lower layers of aluminum profiles. For ease of use, the parting strips are uniformly stored in a parting strip frame. Currently, parting strips are usually manually taken out from the parting strip frame.
Moreover, the parting strips taken out are placed randomly and cannot meet the requirements on automatic production.

[0003] After the parting strips are placed, the parting strips and rows of aluminum profiles are lifted and framed manually, which is time-consuming, laborious and cost-ineffective. Some aluminum profile production enterprises employ an automatic framing machine to frame the aluminum profiles. It mainly includes a longitudinal movement mechanism and a gripping mechanism. The gripping mechanism is configured to grip the parting strips of the aluminum profiles. The longitudinal movement mechanism is configured to deliver the aluminum profiles and the parting strips together to the material frame. Nevertheless, the parting strips are placed manually. In order to align the parting strips and the grid mechanism, there are usually three or less parting strips. As a result, the aluminum profiles are supported insufficiently and are easily damaged in delivery.

[0018] The present disclosure has the following beneficial effects.

[0019] With the cooperation between the parting strip frame, the parting strip delivery device and the aluminum profile framing device, the present disclosure can take out and place the parting strips automatically, and deliver and frame the aluminum profiles automatically, with stable and reliable operation and no manual intervention.

[0020] The parting strip frame can accommodate more parting strips, because the parting strips can be layered and stacked in the frame body, and the parting strips are arranged closely. The bottommost parting strips are supported by the bottom support members. The bottom center of the frame body is hollow, such that the automatic lift mechanism moves up the parting strips from the bottom of the frame body. The end limit members are narrower than the parting strips.
After the parting strips abut against the end limit members, there is a gap between the ends of the parting strips and the frames, and the parting strips can swing horizontally within certain limits.
As a result, the two ends of the parting strips are not stuck in the frame body and are smoothly discharged from the top of the frame body.

[0021] The lift mechanism can lift the parting strips layered and stacked in the parting strip frame. Specifically, an uppermost layer of the parting strips enter the layering mechanism, with two ends of the parting strips pressed and fixed by the layering mechanism.
Then, the lift mechanism drives parting strips other than the uppermost layer of the parting strips to move down, such that the uppermost layer of the parting strips are separated from the parting strips thereunder. The guide rails are stretched out. The guide rails are located between the uppermost Our Ref: 43970-19 CA National Phase of PCT/CN2021/111374 (FS2214P-CA-PCT) layer of the parting strips and the parting strips thereunder. The layering mechanism releases the uppermost layer of the parting strips, such that the uppermost layer of the parting strips are carried on the guide rails. At last, the uppermost layer of the parting strips are pushed forward by the push assembly along the guide rails. Whenever the push assembly pushes the uppermost layer of the parting strips by a distance equivalent to a width of one parting strip, the endmost parting strip on the guide rails falls onto a feeding conveyor belt of a parting strip placement mechanism, thereby implementing the one-by-one delivery of the parting strips.
With the stable and reliable operation, and the high storage density of the parting strips, the present disclosure can meet the use requirements on the parting strips for a long time after adding one frame of the parting strips.

[0022] The parting strip gripping frame is sequentially connected to the lateral movement mechanism, the vertical movement mechanism and the longitudinal movement mechanism to ensure the stable movement of the parting strip gripping frame. The lateral movement mechanism for stretching a lower end of the parting strip gripping frame to a bottom of each of the parting strips is in the last among the three movement mechanisms.
Therefore, there are fewer components that need to move left and right, and the parting strip gripping frame moves left and right more accurately and sensitively.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the drawings. It should be noted that the orientational terms illustrated or to be illustrated in the specification, such as up, down, left, right, forward, backward, inside and outside, are only based on the accompanying drawings of the present disclosure, and do not form specific limits to the present disclosure.

[0040] As shown in FIG. 1 to FIG. 3, an embodiment of the present disclosure provides a fully automatic framing machine for aluminum profiles, including a parting strip frame 100, a parting strip delivery device 101 and an aluminum profile framing device 102. The parting strip frame 100 includes a frame body 8, end limit members 91 and bottom support members 92. The frame body 8 is composed of rectangular frames 81. The bottom support members 92 are provided at a bottom of the frame body 8 in parallel and configured to support parting strips 3'. The end limit members 91 are vertically provided inside the frame body 8. The end limit members 91 are narrower than the parting strips 3'.

[0041] The parting strip frame can accommodate more parting strips 3', because the parting strips 3' can be layered and stacked in the frame body 8, and the parting strips 3' are arranged closely. The bottommost parting strips 3' are supported by the bottom support members 92. The bottom center of the frame body 8 is hollow, such that the automatic lift mechanism lifts the parting strips 3' from the bottom of the frame body 8. The end limit members 91 are narrower than the parting strips 3'. After the parting strips 3' abut against the end limit members 91, there is a gap between the ends of the parting strips 3' and the frames 81, and the parting strips 3' can swing horizontally within certain limits. As a result, the two ends of the parting strips 3' are not Our Ref: 43970-19 CA National Phase of PCT/CN2021/111374 (FS2214P-CA-PCT) stuck in the frame body 8, and the parting strips 3' are smoothly discharged from the top of the frame body 8.

[0042] Preferably, referring to FIG. 4, the end limit members 91 are of an elongated shape and are arranged in the frame body 8 at a predetermined distance. More preferably, central positions of ends of the parting strips 3' directly face the corresponding ones of the end limit members 91.
With the end limit members 91 directly facing the central positions of the ends of the parting strips 3', point contacts are formed between the parting strips 3' and the end limit members 91 and at the central positions of the ends of the parting strips 3'. Therefore, the parting strips 3' can rotate to some extent while limited, ensuring that multiple layers of stacked parting strips 3' move up and down smoothly in the frame body 8.

[0043] Preferably, the frame body 8 is provided with baffles 82 at two sides corresponding to the ends of the parting strips 3' and hollow portions 83 at the other two sides. With the baffles 82, the parting strips 3' cannot be stretched out from an end direction. Through the hollow portions 83, the use of the parting strips 3' is directly observed by an operator. In order to better support the parting strips 3', the bottom support members 92 each are composed of two rectangular tubes 921 at the bottom of the frame body 8. The rectangular tubes 921 are stretched out from the bottoms of the frames 81 to the center of the frame body 8, and support the two ends of the parting strips 3'.

[0044] As shown in FIG. 5 to FIG. 7, the parting strip delivery device 101 includes a lift mechanism 5, a layering mechanism 6 and a conveyance mechanism 7. The lift mechanism 5 is provided below the parting strips 3', and configured to lift parting strips 3'. The layering mechanism 6 is provided above the lift mechanism 5, and includes a clamping cylinder 61 and clamping plates 62. The clamping plates 62 are provided on a piston rod of the clamping cylinder 61. The clamping plates 62 are symmetrically provided at two sides close to the ends of the parting strips 3'. The clamping plates 62 can move horizontally under the driving of the clamping cylinder 61, thereby fixing or loosening the parting strips 3'. The conveyance mechanism 7 includes guide rails 71, a guide cylinder 72 and a push assembly 73. The guide rails 71 are provided on the guide cylinder 72. The guide rails 71 can be stretched out or retracted back under the driving of the guide cylinder 72. The push assembly 73 is configured to push forward parting strips 3' on the guide rails 71.

[0045] Referring to FIG. 9, the push assembly 73 includes a push frame 731 arranged above the guide rails 71. Two ends of the push frame 731 each are provided with a chainwheel 732. A chain 733 is provided on the chainwheel 732. A push claw 734 is provided on the chain 733. The chainwheel 732 is connected to a push motor 103. The lift mechanism 5 includes a lift plate 51, a lift leadscrew 52 and a leadscrew drive mechanism 53. The lift plate 51 is configured to push a Our Ref: 43970-19 CA National Phase of PCT/CN2021/111374 (FS2214P-CA-PCT) row of parting strips 3 to move up and down together. The lift leadscrew 52 is connected to the lift plate 51, and can move up and down vertically under the driving of the leadscrew drive mechanism 53. The leadscrew drive mechanism 53 includes a motor and a nut. The motor rotationally drives the nut. The nut is sleeved on the lift leadscrew 52.

[0046] In the embodiment, referring to FIG. 11, the lift mechanism 5 can lift the parting strips 3' layered and stacked in the parting strip frame. Specifically, an uppermost layer of the parting strips 3' enter the layering mechanism 6, with two ends of the parting strips 3' pressed and fixed by the layering mechanism 6. Then, the lift mechanism 5 drives parting strips 3b' other than the uppermost layer of the parting strips 3a' to move down, such that the uppermost layer of the parting strips 3a' are separated from the parting strips 3W thereunder. The guide rails 71 are stretched out. The guide rails 71 are located between the uppermost layer of the parting strips 3a' and the parting strips 3b' thereunder. The layering mechanism 6 releases the uppermost layer of the parting strips 3a', such that the uppermost layer of the parting strips 3a' are carried on the guide rails 71. At last, the uppermost layer of the parting strips 3a' are pushed forward by the push assembly 73 along the guide rails 71. Whenever the push assembly 73 pushes the uppermost layer of the parting strips 3a' by a distance equivalent to a width of one parting strip 3a', the endmost parting strip on the guide rails 71 falls onto a feeding conveyor belt 5' of a parting strip placement mechanism, thereby implementing the one-by-one delivery of the parting strips 3'.

[0047] In order to reliably clamp the parting strips 3', as shown in FIG. 8, telescopic posts 621 are provided at sides of the clamping plates 62 close to the parting strips 3', and the telescopic posts 621 are elastically connected to the clamping plates 62. Specifically, limiting holes 622 are formed in the clamping plates 62. The telescopic posts 621 are provided in the limiting holes 622.
Springs 623 are provided between the telescopic posts 621 and bottoms of the limiting holes 622, such that the telescopic posts 621 can be stretched out or retracted back relative to the clamping plates 62. When the clamping plates 62 get close oppositely to firmly press the parting strips 3', the telescopic posts 621 contact the ends of the parting strips 3' first. Any telescopic post 621 corresponding to a longer parting strip 3' has a large retracting amount, such that all parting strip 3' can be reliably clamped.

[0048] In order to clamp the parting strips 3' more reliably and prevent clamped parting strips 3' from turning over, as shown in FIG. 9, locating holes 41 extending inward to the parting strips 3' are formed in the ends of the parting strips 3'. The telescopic posts 621 can be stretched into the locating holes 41. Preferably, two or more telescopic posts 621 can be stretched into each of the parting strips 3'. With the horizontal arrangement of the telescopic posts 621, the parting strips 3' keep horizontal. It is also proposed to design the rectangular telescopic posts 621, such that the Our Ref: 43970-19 CA National Phase of PCT/CN2021/111374 (FS2214P-CA-PCT) single telescopic posts 621 stretched into the locating holes 41 can abut against upper and lower inner walls of the parting strips 3' to prevent the parting strips 3' from turning over.

[0049] Similarly, in order to move the parting strips 3' up and down more stably, as shown in FIG. 6, elastic support posts 511 are provided at two sides of the lift plate 51. The elastic support posts 511 are elastically connected to the lift plate 51. Support trays 512 are provided on tops of the elastic support posts 511. The support trays 512 abut against bottom surfaces of the parting strips 3'. Each of the support trays 512 contacts a corresponding one of the parting strips 3'. The elastic support posts 511 are also connected to the lift plate 51 through springs, such that the elastic support posts 511 can move up and down relative to the lift plate 51, a same vertical row of the parting strips 3' are independently stressed in the lifting process of the parting strips 3', and the phenomenon that the parting strips 3' move up and down unsmoothly due to mutual squeezing and friction is prevented.

[0050] In order to deliver the framed parting strips 3' to the lift mechanism 5, referring to FIG. 6 and FIG. 10, the fully automatic framing machine for aluminum profiles in the embodiment may further include a parting strip frame conveyance mechanism 104. The parting strip frame conveyance mechanism 104 includes a conveyance slide rail 74 and a conveyance slide block 75.
The conveyance slide block 75 is stretched between the lift mechanism 5 and the layering mechanism 6. The conveyance slide block 75 can be slidable on the conveyance slide rail 74. A
bottom of the parting strip frame can be matched with the conveyance slide block 75. The parting strip frame can move on the conveyance slide rail 74 with the conveyance slide block 75.

[0051] As shown in FIG. 12, the aluminum profile framing device 102 includes a longitudinal movement mechanism 1, a lateral movement mechanism 2, a vertical movement mechanism 3 and a parting strip gripping frame 4. The longitudinal movement mechanism 1 is configured to drive the vertical movement mechanism 3 to move forward and backward. The vertical movement mechanism 3 is configured to drive the lateral movement mechanism 2 to move up and down. The lateral movement mechanism 2 is configured to drive the parting strip gripping frame 4 to move left and right. The parting strip gripping frame 4 includes a frame body 41.
Gripping claws 42 extending downward are symmetrically provided at two sides of the frame body 41.

[0052] In the embodiment, the parting strip gripping frame 4 is sequentially connected to the lateral movement mechanism 2, the vertical movement mechanism 3 and the longitudinal movement mechanism 1 to ensure the stable movement of the parting strip gripping frame 4. The lateral movement mechanism 2 for stretching a lower end of the parting strip gripping frame 4 to a bottom of each of the parting strips is in the last among the three movement mechanisms.
Therefore, there are fewer components that need to move left and right, and the parting strip Our Ref: 43970-19 CA National Phase of PCT/CN2021/111374 (FS2214P-CA-PCT) gripping frame 4 moves left and right more accurately and sensitively.

[0053] Referring to FIG. 13, the longitudinal movement mechanism 1 includes a bracket 11, a longitudinal guide rail 12, a longitudinal movement frame 13 and a longitudinal drive mechanism 14. The bracket 11 is stretched across an aluminum profile discharging station l' and a framing station 105. The longitudinal guide rail 12 is provided on the bracket 11. The longitudinal movement frame 13 is supported on the bracket 11, and can move forward and backward along the longitudinal guide rail 12. The longitudinal drive mechanism 14 is configured to drive the longitudinal movement frame 13 to move forward and backward relative to the bracket 11.

[0054] The longitudinal drive mechanism 14 includes a longitudinal drive motor 141, a first synchronizing shaft 142, first synchronizing gears 143, and first racks 144 in a same direction as the longitudinal guide rail 12. The first racks 144 are provided on the bracket 11. The longitudinal drive motor 141, the first synchronizing shaft 142 and the first synchronizing gears 143 are arranged on the longitudinal movement frame 13. The synchronizing gears are provided at two ends of the synchronizing shaft 142. The first synchronizing gears 143 are meshed with the first racks 144. The longitudinal drive motor 141 is configured to rotationally drive the first synchronizing shaft 142. When the longitudinal movement frame 13 is necessarily driven to move forward and backward, the longitudinal drive motor 141 rotationally drives the first synchronizing gears 143 through the first synchronizing shaft 142. As the first racks 144 fixed on the bracket 11 rotate with the first synchronizing gears 143, the longitudinal movement frame 13 moves forward and backward relative to the bracket 11. The longitudinal guide rail 12 provides a guiding function for the longitudinal movement frame 13.

[0055] As shown in FIG. 14, the vertical movement mechanism 3 includes a vertical guide post 31, a vertical guide sleeve 32, a vertical movement plate 33 and a vertical drive mechanism 34.
The vertical guide sleeve 32 is provided on the longitudinal movement frame 13. The vertical movement plate 33 is provided at a lower end of the vertical guide post 31.
The vertical guide post 31 is nested in the vertical guide sleeve 32. The vertical drive mechanism 34 is configured to drive the vertical guide post 31 to move up and down relative to the longitudinal movement frame 13.

[0056] The vertical drive mechanism 34 includes a lift drive motor 341, a second synchronizing shaft 342, second synchronizing gears 343, and second racks 344. The lift drive motor 341, the second synchronizing shaft 342 and the second synchronizing gears 343 are arranged on the longitudinal movement frame 13. The second racks 344 are fixedly connected to the vertical movement plate 33. The second synchronizing gears 343 are provided at two ends of the second synchronizing shaft 342. The second synchronizing gears 343 are meshed with the second racks Our Ref: 43970-19 CA National Phase of PCT/CN2021/111374 (FS2214P-CA-PCT) 344. The lift drive motor 341 is configured to rotationally drive the second synchronizing shaft 342. When the longitudinal movement frame 13 is necessarily driven to move up and down, the lift drive motor 341 rotationally drives the second synchronizing gears 343 through the synchronizing shaft, thereby driving the second racks 344 to move up and down.
The longitudinal movement frame 13 connected to the second racks 344 also moves up and down therewith. With the vertical guide post 31 and the vertical guide sleeve 32, the longitudinal movement frame 13 moves up and down more stably.

[0057] As shown in FIG. 16, the lateral movement mechanism 2 includes a vertical movement plate connecting frame 21, a lateral slide mechanism 22 and a lateral drive mechanism 23. The vertical movement plate connecting frame 21 is connected to the frame body 41 through the lateral slide mechanism 22. The frame body 41 can move left and right relative to the vertical movement plate connecting frame 21. The lateral drive mechanism 23 is configured to drive the frame body 41 to move left and right relative to the vertical movement plate connecting frame 21.
The vertical movement plate connecting frame 21 is fixedly connected to the vertical movement plate 33. Preferably, the lateral drive mechanism 23 may be a cylinder connected to the frame body 41 and the vertical movement plate connecting frame 21. The lateral slide mechanism 22 may include a slide rail 221 and a slide block 222. Either the slide rail 221 or the slide block 222 is connected to the frame body 41, and the other is connected to the vertical movement plate connecting frame 21. When the frame body 41 is necessarily driven to move left and right, the cylinder is stretched out or retracted back, such that the frame body 41 moves left and right relative to the vertical movement plate connecting frame 21.

[0058] Referring to FIG. 15, the lift drive motor 341 as the component with the maximum mass in the whole vertical movement mechanism is crucial to the stability of the longitudinal movement frame 13 in operation. Preferably, the lift drive motor 341 is fixed at a horizontal center of the longitudinal movement frame 13 through a motor fixing frame 345, such that a center of gravity of the lift drive motor 341 is located at the horizontal center of the longitudinal movement frame 13. Therefore, during movement of the longitudinal movement frame 13, the longitudinal movement frame 13 moves more stably with less shaking of the longitudinal movement frame 13.

[0059] More preferably, in order that an overall center of the lift drive motor 341 and a gearbox matched with the lift drive motor 341 is located at a same height as the longitudinal movement frame 13, the motor fixing frame 345 is composed of two symmetrical U-shaped rods. The lift drive motor 341 and the gearbox 346 matched with the lift drive motor 341 are arranged on the U-shaped rods. With the above design, when a movement speed of the longitudinal movement frame 13 changes, the longitudinal movement frame 13 is not turned over for the lift drive motor Our Ref: 43970-19 CA National Phase of PCT/CN2021/111374 (FS2214P-CA-PCT) 341 and the gearbox 346 matched with the lift drive motor 341, and the longitudinal movement frame 13 can be stopped accurately at a predetermined position.

[0060] Preferably, as shown in FIG. 17, the gripping claws 42 each include a connection rod 421 and a carrier plate 422 at a tail end of the connection rod 421. A
position sensor 411 for sensing a position of the aluminum profile is further provided on the frame body 41. A sensing position of the position sensor 411 is as high as a position of the carrier plate 422.

[0061] Preferably, a pressure sensor 412 is provided on the carrier plate 422 or at a junction between the carrier plate 422 and the connection rod 421. The pressure sensor 412 is configured to detect a pressure of the aluminum profile or each of the parting strips to a bottom of the carrier plate 422. When any parting strip is located at an inaccurate position, the carrier plate 422 moving down may press the parting strip. In this case, the pressure sensor 412 senses the pressure and can give an alarm and control the system to shut down, for fear of the snap of the parting strip or damage to the carrier plate 422, etc.

[0062] Descriptions will be made below in detail to the working principle in the embodiment:

[0063] I. Taking-out and placement of the parting strips

[0064] 1. The framed parting strips 3' are placed on the conveyance slide block 75, and the parting strip frame slides to the lift mechanism 5 along the conveyance slide rail 74.

[0065] 2. The leadscrew drive mechanism 53 of the lift mechanism 5 drives the lift leadscrew 52 to move up. The lift plate 51 on the lift leadscrew 52 pushes the bottoms of the parting strips 3' to move up the parting strips 3' overall.

[0066] 3. When the uppermost layer of the parting strips 3' reaches a predetermined height, the clamping plates 62 are stretched out under the pushing of the clamping cylinder 61 to clamp and fix the uppermost layer of the parting strips 3'.

[0067] 4. The lift mechanism 5 drives remaining parting strips 3' to move down, such that the uppermost layer of the parting strips 3a' are separated from the remaining parting strips 3b'.

[0068] 5. The guide rails 71 are stretched out under the driving of the guide cylinder 72. The guide rails 71 are located between the uppermost layer of the parting strips 3a' and the parting strips 3b' thereunder. The layering mechanism 6 releases the uppermost layer of the parting strips 3a', such that the uppermost layer of the parting strips 3a' are carried on the guide rails 71.

[0069] 6. Referring to FIG. 19, the push motor rotationally drives the chainwheel 732, such that the chain 733 on the chainwheel 732 rotates therewith. The push claw 734 on the chain 733 contacts the uppermost layer of the parting strips 3', and pushes the parting strips forward along the guide rails 71. Whenever the push assembly 73 pushes the uppermost layer of the parting strips 3' by a distance equivalent to a width of one parting strip 3', the endmost parting strip 3' on the guide rails 71 falls onto the feeding conveyor belt 5' of the parting strip placement Our Ref: 43970-19 CA National Phase of PCT/CN2021/111374 (FS2214P-CA-PCT) mechanism, thereby implementing the one-by-one delivery of the parting strips 3'.

[0070] The solution can separate and deliver the parting strips 3' one by one.
With the stable and reliable operation, and the high storage density of the parting strips 3', the present disclosure can meet the use requirements on the parting strips 3' for a long time after adding one frame of the parting strips 3'.

[0071] II. Delivery and framing of the aluminum profile

[0072] 1. The feeding conveyor belt 5' of the parting strip placement mechanism conveys the parting strips at a predetermined distance to be below the aluminum profile to be delivered.

[0073] Referring to FIG. 18, in an initial state, the carrier plate 422 is located above the aluminum profile discharging station l', and the vertical movement mechanism 3 drives the carrier plate 422 to move downward. When moving to be below the parting strips 3', the carrier plate 422 is driven by the lateral movement mechanism 2 to translate toward the parting strips, such that the carrier plate 422 is located below the parting strips 3'.

[0074] 2. While the vertical movement mechanism 3 drives the carrier plate 422 to move up, the parting strips 3' and the aluminum profile 4' on the parting strips 3' move up, either.

[0075] 3. Once being in place, the parting strips 3' and the aluminum profile 4' are delivered by the longitudinal movement mechanism 1 to the framing station at a side of the aluminum profile discharging station. There is a material frame 2' at the framing station 105.

[0076] 4. The vertical movement mechanism 3 drives the carrier plate 422 to move down. When the parting strips 3' and the aluminum profile 4' are delivered to the material frame, the carrier plate 422 is separated from the parting strips 3'. The lateral movement mechanism 2 drives the carrier plate 422 to translate toward a direction away from the parting strips, and the carrier plate 422 leaves away from the parting strips 3'.

[0077] 5. The carrier plate 422 is restored to deliver a next batch of aluminum profiles.
