Description

Technical Field

[0002] In the existing separation membrane shell production technology, membrane shells removed from the mold by membrane shell demolding equipment are supported by fixed supports or movable supports on ground rails. Once the membrane shells are removed from the mold, they cannot be connected to automated transfer equipment such as AGVs due to limitations on the ground rails or fixed supports. They must be hoisted, which is inefficient. Furthermore, the next demolding operation requires manual return of the ground rail supports, and integration with modern intelligent logistics technologies is impossible. Due to these traditional structural limitations, intelligent logistics transfer technologies in membrane shell production cannot be implemented.

[0062] The working process of the supporting connection device of the membrane shell demoulding equipment:

[0063] The membrane shell demolding equipment's supporting connection device is equipped with multiple sensors, controlled by a PLC. These sensors can be installed on the multi-station demolding machine 100 or at a designated location as needed. Initially, the front follower trolley 2 is attached to the end of the multi-station demolding machine 100, the front membrane shell support base 2-3 drops, and the rear power trolley 3 is attached to the end of the front follower trolley 2. The front membrane shell support base 2-3 drops, the electromagnetic clutch 3-12 loses power, and the powered directional wheels of the rear wheel assembly are in a free-wheeling state. The multi-station demolding machine 100 ejects the membrane shell. The end of the ejected membrane shell blank 200 strikes the workpiece stop bar 3-6 of the rear power trolley 3, pushing the rear power trolley 3 backward. Guided by the side guide brackets 3-10 and guide pulleys 3-11, as well as the C-channel steel track, the rear power trolley 3 moves backward along the predetermined path. When the membrane shell blank 200 hits the workpiece blocking rod 3-6, the rear vehicle proximity switch 3-15 is triggered first. When the rear vehicle proximity switch 3-15 is triggered, the rear vehicle DC hydraulic pump station receives a signal and supplies oil to the lifting direction of the rear vehicle hydraulic cylinder 3-2, thereby raising the rear vehicle membrane shell lifting seat 3-3 and the rear vehicle hydraulic cylinder limit plate. After the rear vehicle limit protrusion on the rear vehicle hydraulic cylinder limit plate triggers the rear vehicle upper limit proximity switch, the rear vehicle membrane shell lifting seat 3-3 stops rising. The friction between the rear vehicle membrane shell lifting seat 3-3 and the membrane shell blank 200 can also cause the rear power trolley 3 to move backward with the membrane shell blank 200. Under the action of the workpiece blocking rod 3-6 and the rear vehicle membrane shell lifting seat 3-3, the rear power trolley 3 moves backward with the membrane shell blank 200.

[0064] The multi-station demoulding machine 100 has a moving device on the demoulding device. When the leading edge of the moving device on the demoulding device approaches the first front vehicle proximity switch 2-8 of the front follower trolley 2, the first front vehicle proximity switch 2-8 is triggered. The front vehicle DC hydraulic pump station 2-11 of the front follower trolley 2 receives the signal and supplies oil to the lifting direction of the front vehicle hydraulic cylinder 2-2. The front vehicle membrane shell lifting seat 2-3 rises, and the front vehicle hydraulic cylinder limit plate 2-5 rises accordingly. After the front vehicle limit protrusion on the front vehicle hydraulic cylinder limit plate 2-5 triggers the front vehicle upper limit proximity switch 2-6, the front vehicle membrane shell lifting seat 2-3 stops rising. Under the action of the friction between the front vehicle membrane shell lifting seat 2-3 and the membrane shell blank 200, the front follower trolley 2 moves backward synchronously with the membrane shell blank 200.

[0065] A limit switch is installed at the end of the multi-station demoulding machine 100. This limit switch is triggered when the multi-station demoulding machine 100 reaches its maximum travel, indicating that the demoulding operation is complete. This signal is then sent to the front follower trolley 2 and the rear power trolley 3, causing the front and rear DC hydraulic pump stations 2-11 and 3-2 to operate simultaneously, supplying oil to the front and rear hydraulic cylinders 2-2 and 3-2, respectively, in the downward direction. The front limit protrusion on the front hydraulic cylinder limit plate 2-5 triggers the front lower limit proximity switch 2-7, causing the front DC hydraulic pump station 2-11 to stop operating. The rear limit protrusion on the rear hydraulic cylinder limit plate triggers the rear lower limit proximity switch, causing the rear DC hydraulic pump station to stop operating. At this point, the membrane shell blank 200 has been released from the multi-station demoulding machine 100 and is supported by the front follower trolley 2 and rear power trolley 3, ready for transport. At this time, the middle position between the front follower trolley 2 and the rear power trolley 3 allows automatic logistics equipment such as AGV to enter, and lift and transport the membrane shell blank 200 away.

[0066] After the membrane shell blank 200 is transported away, the call button is pressed, and the electromagnetic clutch 3-12 of the rear power trolley 3 is energized and attracted. At the same time, the reduction motor 3-16 is activated, which drives the driving sprocket 3-13 at the end of the electromagnetic clutch 3-12 to rotate. The driving sprocket 3-13 drives the driven sprocket 3-14 through the chain. The driven sprocket 3-14 is fixed to the axle of the rear power directional wheel 3-5, driving the rear power directional wheel 3-5 toward the multi-station demoulding machine 100. Under the constraints of the side track 1 and the guide track 4, the rear power trolley 3 returns along the original path. When the rear power trolley 3 reaches the front follower trolley 2, it pushes the front follower trolley 2 back together. When the front follower trolley 2 approaches the multi-station demoulding machine 100, the second front vehicle proximity switch 2-9 of the front follower trolley 2 is triggered, the electromagnetic clutch 3-12 is de-energized, and the rear power trolley stops and waits for the next work.

[0067] The membrane shell demolding equipment is equipped with a connecting device that automatically connects the membrane shell blank 200 during the demolding process, moving it synchronously with the workpiece. After demolding, it can be returned to its original position with a single click. This device, while providing automatic connection during demolding, avoids the need for laying tracks along the route, providing support for existing automated navigation technologies such as magnetic strip navigation and laser navigation.
