[0003] In the intelligent hanging conveying technology disclosed in the existing patent, the workstation guide rail can only be extended from the input end to the output end. The guiding track is horizontally arranged at the bottom of the workstation by bending through a bending disc. This design occupies a relatively large volume of the overall device. At the same time, space needs to be reserved for setting up sewing processing positions. Since each workstation occupies a relatively large space, the number of workstations set will be limited, and the working efficiency needs to be improved. At the same time, the existing hanging has high space requirements, and many factories with low ceiling heights cannot arrange hanging, which affects the installation and application of hanging.

[0020] The following further describes the embodiments of the present utility model in detail with reference to the drawings.

[0022] The reference numerals therein are: main rail 1, first workstation guide rail 2, in-station cylinder 3, in-station cylinder joint 4, swing drive handle 5, swing head 6, guiding slideway 7, backing plate 8, flow control cylinder 9, flow control mounting seat 10, flow control cylinder joint 11, drive handle 12, limit hook 13, control handle 13a, cylinder mounting bracket 14, rodless cylinder 15, cylinder housing 16, spiral groove 17, drive mounting seat 18, guiding rod 19, lifting and conveying seat 20, lifting connecting plate 20a, input part 20b, staying part 20c, left baffle 20d, right baffle 20e, docking opening groove 20f, second workstation guide rail 21, first staying section 21a, lifting section 21b, second staying section 21c, docking guide rail 22, chain mounting seat 23, first motor 24, motor mounting seat 25, conveyor chain 26, driving gear 27, gear mounting vertical plate 28, first gear 29, second gear 30, third gear 31, upper fixing plate 32, lower fixing plate 33, lifting seat 34, lifting connecting plate 34a, lifting bottom plate 34b, lifting vertical plate 34c, top plate part 34d, mounting bracket 35.

[0023] As Figure 1 and Figure 2 shown, the intelligent hanging production line of the present utility model includes a main rail 1 for conveying material hangings, and a plurality of workstation units are arranged along the main rail 1. The workstation unit includes a mounting bracket 35, a first workstation guide rail 2, a spiral descending mechanism, a lifting arm mechanism, and a second workstation guide rail 21 fixed on the mounting bracket 35. The material hanging is input from the main rail 1 to the first workstation guide rail 2, the spiral descending mechanism descends and rotates the material hanging by a certain angle and then transports it to the second workstation guide rail 21, the lifting arm mechanism conveys the sewn material hanging upward along the second workstation guide rail 21, and finally the second workstation guide rail 21 controls the output of the material hanging to the main rail 1.

[0024] As Figure 3 shown, an in-station mechanism connected to the main rail 1 is installed at the front end of the first workstation guide rail 2. The in-station mechanism includes an in-station cylinder 3 and a swing head 6 equipped with a guiding slideway 7. The in-station cylinder 3 is connected to the in-station cylinder joint 4, the in-station cylinder joint 4 is rotatably connected to the swing drive handle 5, and the swing drive handle 5 is fixedly connected to the swing head 6. The in-station cylinder 3 drives the swing head 6 to swing up and down. The front end of the swing head 6 has a guiding slideway 7 and a backing plate 8. The in-station cylinder 3 can drive the swing head 6 to drop, so that the guiding slideway 7 contacts the main rail 1, guiding the hanging roller to enter the first workstation guide rail 2 along the guiding slideway 7. The in-station cylinder 3 drives the swing head 6 to lift, the guiding slideway 7 leaves the main rail 1, and the hanging roller on the main rail 1 can cross this workstation and continue to be conveyed.

[0025] The rear end of the first workstation guide rail 2 extends to the upper working position of the spiral descending mechanism. A first flow control mechanism is installed at the rear end of the first workstation guide rail 2. After multiple material suspension hangers slide from the main rail 1 to the first workstation guide rail 2 of the same workstation, they can temporarily stay at the rear end of the first workstation guide rail 2, and the first flow control mechanism controls the quantity and timing of the material suspension hangers output to the spiral descending mechanism.

[0026] As Figure 4 shown, the first flow control mechanism includes a flow control mounting seat 10, a flow control cylinder 9, and a rotatable limit hook 13. The flow control mounting seat 10 is fixedly connected to the mounting bracket 35. The cylinder body of the flow control cylinder 9 is rotatably installed on the flow control mounting seat 10, and the piston rod of the flow control cylinder 9 is connected to the flow control cylinder joint 11. The flow control mounting seat 10 has a mounting groove, and the limit hook 13 is rotatably installed below the mounting groove. The driving handle 12 of the limit hook 13 passes upward through the mounting groove and is rotatably connected to the flow control cylinder joint 11. The limit hook 13 has a control handle 13a extending forward.

[0027] The flow control cylinder 9 can drive the limit hook 13 to rotate to lift the rear part of the limit hook 13, facilitating the output of the last hanger roller on the first workstation guide rail 2 along the track. At this time, the front control handle 13a is in a lowered state, blocking other hanger rollers from sliding out of the first workstation guide rail 2. Subsequently, the flow control cylinder 9 drives the limit hook 13 to rotate to lower the rear part. At this time, the front control handle 13a is in a raised state, and the hanger roller blocked by the control handle 13a can move a certain distance and be blocked by the rear part of the limit hook 13, causing the hanger roller to stop.

[0028] As Figure 5 shown, the spiral descending mechanism includes a cylinder mounting frame 14, a rodless cylinder 15, and a cylinder housing 16 sleeved outside the rodless cylinder 15. The upper and lower ends of the rodless cylinder 15 are respectively fixedly connected to the mounting bracket 35 through the cylinder mounting frame 14. The rodless cylinder 15 is vertically arranged, and the cylinder housing 16 is installed outside the rodless cylinder 15. The cylinder housing 16 is provided with a spiral groove 17 along the movement direction of the slider. One end of the spiral groove 17 is located at the upper end of the cylinder housing 16, and the other end of the spiral groove 17 is located at the lower end of the cylinder housing 16.

[0029] A rotatable driving mounting seat 18 is provided on the slider of the rodless cylinder 15. A guide rod 19 is fixed to the driving mounting seat 18. The guide rod 19 passes through the spiral groove 17 and is connected to the lifting and conveying seat 20. When the slider of the rodless cylinder 15 drives the driving mounting seat 18 to move up and down, the guide rod 19 moves along the spiral groove 17, driving the driving mounting seat 18 to rotate in the horizontal direction. In this embodiment, when the driving mounting seat 18 descends from the upper end to the lower end, the driving mounting seat 18 rotates about 90 degrees, so that the lifting and conveying seat 20 just docks with the input end of the second workstation guide rail 21.

[0030] As needed, the helical groove 17 of the cylinder housing 16 can have different helix angles, and the corresponding driving mounting seat 18 can rotate at an angle of 60 degrees to 360 degrees in the horizontal direction. The helical descent mechanism is arranged between the output end of the first workstation guide rail 2 and the input end of the second workstation guide rail 21, enabling a relatively large drop between the output end of the first workstation guide rail 2 and the input end of the second workstation guide rail 21, avoiding the defect in the prior art that a track rotary connection must be used, resulting in a large space occupation of the workstation.

[0031] As Figure 6 shown, the lifting and conveying seat 20 includes a lifting connection plate 20a fixedly connected to the guide rod 19, an input portion 20b and a stay portion 20c integrally connected to the lifting connection plate 20a. The bottom surface of the stay portion 20c has an integrally concave arc surface, and the arc surface conforms to the radian of the hanging roller in the material hanging. When the lifting and conveying seat 20 conveys the hanging roller, the hanging roller can stay stably. The input portion 20b has an input plate that docks with the hanging roller at the end of the first workstation guide rail 2, and the hanging roller can slide into the stay portion 20c along the input plate. The stay portion 20c has a left baffle 20d and a right baffle 20e that bend upward in the middle. The left baffle 20d and the right baffle 20e extend towards the input portion 20b and just fit into the groove in the middle of the hanging roller, preventing the hanging roller from detaching from the lifting and conveying seat 20 due to shaking. The stay portion 20c is provided with a docking opening groove 20f between the left baffle 20d and the right baffle 20e, and the docking opening groove 20f extends straight to the rear of the stay portion 20c. The width of the docking opening groove 20f is greater than the distance between the left baffle 20d and the right baffle 20e.

[0032] After the first flow control mechanism is opened, the last material on the first workstation guide rail 2 is hung under the action of gravity, causing the hanging roller to slide into the lifting and conveying seat 20 at the upper working position. The helical descent mechanism spirally conveys the material hanging to the lower working position and makes the hanging roller slide into the input end of the second workstation guide rail 21.

[0033] The second workstation guide rail 21 includes a first stop section 21a, a lifting section 21b, and a second stop section 21c. At the input end of the first stop section 21a, a docking guide rail 22 is installed. The docking guide rail 22 can pass through the docking opening slot 20f and is exactly inserted between the left baffle 20d and the right baffle 20e. When the lifting and conveying seat 20 slides downward, the docking guide rail 22 picks up the hanging roller between the left baffle 20d and the right baffle 20e, and the hanging roller slides along the docking guide rail 22 into the first stop section 21a. The first stop section 21a is a slightly downward-sloping track, and the clothing hanging guide slides to the end of the first stop section 21a for convenient sewing processing. The second stop section 21c is located above the main rail 1. A second flow control mechanism is installed on the second stop section 21c, and the structure of the second flow control mechanism is the same as that of the first flow control mechanism. An outbound mechanism is installed at the end of the second stop section 21c, and the structure of the outbound mechanism is the same as that of the inbound mechanism. After the sewn materials are hung and conveyed to the second stop section 21c, they are controlled by the second flow control mechanism and output to the main rail 1. The lifting section 21b connects the first stop section 21a and the second stop section 21c. A lifting arm mechanism is provided on one side of the lifting section 21b for lifting the hanging materials along the lifting section 21b to the second stop section 21c.

[0034] As Figure 7 shown, the lifting arm mechanism includes a chain mounting seat 23 fixed on the mounting bracket 35. A first motor 24, a driving gear 27, a first gear 29, a second gear 30, a third gear 31, a transmission chain 26, and a lifting seat 34 are installed on the chain mounting seat 23. The first motor 24 is installed at the end of the chain mounting seat 23 through a motor mounting seat 25, and the power output shaft of the first motor 24 is connected to the driving gear 27. A gear mounting vertical plate 28 is fixed at the other end of the chain mounting seat 23. The first gear 29, the second gear 30, and the third gear 31 are distributed in a triangle and are rotatably installed on the gear mounting vertical plate 28. The transmission chain 26 is sleeved on the driving gear 27, the first gear 29, the second gear 30, and the third gear 31.

[0035] The upper part of the chain mounting seat 23 is connected with an upper fixing plate 32, and the lower part of the chain mounting seat 23 is connected with a lower fixing plate 33. The upper fixing plate 32 and the lower fixing plate 33 are fixedly connected to the second workstation guide rail 21.

[0036] The first motor 24 drives the driving gear 27 to rotate, the driving gear 27 drives the transmission chain 26 to move, and the lifting seat 34 on the transmission chain 26 pushes the hanging roller located on the first stop section 21a and moves upward along the lifting section 21b to the second stop section 21c.

[0037] As Figure 8 shown, the lifting seat 34 includes a lifting connecting plate 34a fixedly connected to the link of the transmission chain 26. A lifting bottom plate 34b is rotatably installed on the lifting connecting plate 34a, and a lifting vertical plate 34c is made on one side of the lifting bottom plate 34b.

[0038] The lifting base plate 34b has a groove, and the radian of the groove exactly corresponds to the outer shape of the guide rail 21 of the second workstation. When the lifting seat 34 rises, the guide rail 21 of the second workstation is located in the groove of the lifting base plate 34b. The hanging roller is located between the lifting connection plate 34a and the guide rail 21 of the second workstation, can stably stay on the lifting base plate 34b, and can be lifted along the lifting section 21b of the guide rail 21 of the second workstation.

[0039] As Figure 9 shown, a rotating shaft is installed between the lifting connection plate 34a and the lifting base plate 34b. The lifting vertical plate 34c extends towards the back of the lifting connection plate 34a and is provided with a top plate portion 34d extending upwards. When the lifting seat 34 rises, the lifting connection plate 34a and the lifting base plate 34b are in an unfolded state, and the top plate portion 34d of the lifting vertical plate 34c abuts against the back of the lifting connection plate 34a, restricting the unfolding angle between the lifting connection plate 34a and the lifting base plate 34b. When the lifting seat 34 descends, under the action of gravity, the lifting base plate 34b rotates around the rotating shaft and folds onto the lifting connection plate 34a.

[0040] The best embodiments of the present invention have been illustrated, and various changes or modifications made by those of ordinary skill in the art will not depart from the scope of the present invention.
