Description

Technical Field

[0001] This invention relates to the field of suspended conveyor technology, specifically to an adjustable suspended conveyor system for decorative printed materials. Background Technology

[0002] Common decorative printed materials that require the use of suspended conveyors include rigid cardboard boxes such as paper gift boxes, cosmetic packaging boxes, and electronic product boxes, which need to be kept flat by suspension clamps to avoid compression and deformation; promotional banners and large posters, which can be prevented from curling and wrinkling by suspension transport; or some decorative ornaments and printing consumables.

[0003] Patent document CN108840031B discloses a convenient suspended conveying system and a suspended conveyor for spraying, including a track system, an accumulation train set, and a control system. The track system includes a linear conveying section supported by a steel structure frame, a traversing device, a turnout device, and a slewing device. The linear conveying section includes a straight rail and a traction drive device. The straight rail includes parallel reinforcing beams and C-shaped rails, with a connecting beam perpendicularly arranged between the reinforcing beams and the C-shaped rails. The C-shaped rails open downwards. This application possesses the operating characteristics of a continuous and accumulation suspended conveying device, enabling interval operation, reducing energy consumption, and improving efficiency.

[0004] As mentioned in the prior art of the aforementioned patent, suspended transportation requires a suspension mechanism, a steel structure guide rail, and a drive mechanism. The common suspension mechanism is fixed to a conveyor chain, which drives the suspension mechanism to move. However, in production and transportation, different items require either a suspended type or a clamping type. When using it, one clamp needs to be removed before another clamp can be installed, resulting in frequent changes. In addition, there are irregularly shaped products, such as curved products, where common clamps have limitations and can easily reduce the clamping effect, leading to the risk of items falling. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable suspended conveyor system for decorative printed materials, which solves the problems mentioned in the background section.

[0018] In the above technical solution, the beneficial effects of the present invention are: by pointing the heavier side of the irregularly shaped item toward the guide post, when the item enters the mounting slot, the bottom of the drive rod will drive the first rack, causing the counterweight to move, thereby adjusting the center of gravity of the device and improving its balance. On the other hand, when the lower side of the item is in the mounting slot, the square plate will elastically clamp the side of the item, realizing clamping of the upper and lower sides of the item and improving its stability.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1: Please refer to Figures 1 to 7 The present invention provides a technical solution: an adjustable hanging conveyor system for decorative printed materials, including a guide rail 1 and a drive mechanism disposed on the guide rail 1;

[0036] It also includes a suspension assembly, which includes a first clamping wheel 2 and a second clamping wheel 21 that are movably installed on both sides of the guide rail 1. A locking block 24 is provided in the first clamping wheel 2. A first bolt 25 is threadedly connected to the locking block 24, and a hook 26 is fixedly installed at the bottom of the first bolt 25.

[0037] The clamping assembly includes a mounting module and a clamping module. The mounting module includes a fixing plate 3 disposed on the hook 26 and a second nut 31 threadedly connected to the hook 26, which is used to mount the clamping module, simplify the chuck replacement process, and improve usage efficiency.

[0038] The clamping module includes a bidirectional electric push rod 32 mounted on the hook 26, and an adjusting stud 33 fixedly mounted on the output shaft of the bidirectional electric push rod 32. A mounting bracket 35 is movably mounted on the adjusting stud 33, and a first electric push rod 36 is fixedly mounted on the mounting bracket 35. An adaptive spring 38 is fixedly mounted between the two mounting brackets 35.

[0039] Specifically, the drive mechanism includes a servo motor 11 fixedly mounted on the guide rail 1, and a transmission disk 12 fixedly connected to the output shaft of the servo motor 11. A transmission chain 13 is driven onto the transmission disk 12. The suspension assembly also includes a first stud 22 and a first nut 23. In use, the first clamping wheel 2 and the second clamping wheel 21 are first placed on both sides of the guide rail 1, the first stud 22 is passed through the first clamping wheel 2 and the second clamping wheel 21, and the two first nuts 23 on the outer surface of the first stud 22 are tightened to make them in close contact with the first clamping wheel 2 and the second clamping wheel 21, thereby completing the installation of the first clamping wheel 2 and the second clamping wheel 21. Next, the transmission chain 13 is placed inside the first clamping wheel 2 and secured by the locking block 24. Then, the first bolt 25 is screwed into the first clamping wheel 2 through the locking block 24 to complete the installation. The installation between the transmission chain 13, the first clamping wheel 2, and the second clamping wheel 21 is carried out, and the hook 26 is designed on the nut of the first bolt 25. When tightening or loosening the first bolt 25, the hook 26 can be used to assist the force, thus eliminating the need to use a screwdriver. The hook 26 has an external thread on its vertical part. When some items are not suitable for hanging with the hook, a clamping module can be used. In traditional applications, the hook needs to be disassembled and the clamping module needs to be installed, which is cumbersome. In this invention, the clamping module can be directly connected to the hook 26 through the external thread design of the hook 26. During operation, the bidirectional electric push rod 32 is first placed inside the hook 26, then the fixing plate 3 is snapped onto the outside of the hook 26 and the bidirectional electric push rod 32 is pressed. Then the second nut 31 is tightened to complete the installation of the bidirectional electric push rod 32.

[0040] Furthermore, the clamping module also includes a third nut 34 threaded onto the outer surface of the adjusting stud 33, and a support plate 37 hinged to the output shaft of the first electric push rod 36. In this invention, both sides of the adjusting stud 33 are provided with adapting springs 38 for clamping the item. Before clamping, the mounting bracket 35 is adjusted according to the thickness of the item so that the two adapting springs 38 are close to the item. Then, the third nut 34 is tightened, and the first electric push rod 36 is activated so that the support plate 37 presses against the adapting springs 38 to complete the clamping of the item. On the other hand, during production, in addition to flat items, there are also items with curved ends. In this case, the bidirectional electric push rod 32 needs to be activated to move the mounting bracket 35, so that the mounting bracket 35 presses against the adapting springs 38, causing them to bend and then make the adapting springs 38 fit against the curved surface of the item. Then, the first electric push rod 36 is activated so that the support plate 37 clamps the item, completing multi-point clamping, as shown in the attached instruction manual. Figure 7 As shown.

[0041] Example 2: Please refer to Figures 8 to 12It also includes a load-bearing component, which includes a telescopic module, a load-bearing module, a limiting module and a balancing module. The telescopic module includes a connector 4 fixedly connected to the mounting bracket 35, and a second electric push rod 42 fixedly installed on the connector 4. A connecting block 43 is fixedly installed on the output shaft of the second electric push rod 42.

[0042] The load-bearing module includes a balance plate 44 disposed on the connecting block 43, a bracket 45 movably mounted on the balance plate 44, and a load-bearing plate 46 movably mounted on the other end of the bracket 45.

[0043] The limiting module includes a guide post 48 disposed on the bearing plate 46 and a first spring 49 sleeved on the outer periphery of the guide post 48. An adjusting block 410 is movably mounted on the outer surface of the guide post 48. A rotating shaft 411 is provided on the adjusting block 410. A drive rod 412 is movably mounted in the middle of the outer surface of the rotating shaft 411.

[0044] The balance plate 44 is fixedly installed with a second stud 415 on one side and the bottom. The outer surface of the second stud 415 is threaded with a fourth nut 416. The connecting block 43 is provided with a through groove that matches the second stud 415.

[0045] A square plate 413 is fixedly installed on the side of the drive rod 412 near the rotating shaft 411, and a third bolt 414 is threadedly connected to one end of the drive rod 412.

[0046] The balancing module includes a second spring 5 disposed on the balancing plate 44 and a first rack 51 fixedly connected to the second spring 5. A gear 52 is engaged on one side of the first rack 51, and a second rack 53 is engaged on the other side of the gear 52. A counterweight 54 is provided at one end of the second rack 53.

[0047] The balance plate 44, the bracket 45 and the bearing plate 46 are all provided with screw holes, and the fourth bolt 417 is threaded into the screw holes.

[0048] A mounting frame 55 is fixedly installed at the bottom of the balance plate 44. The gear 52 is movably installed with the mounting frame 55. The mounting frame 55 is installed in a staggered manner with the counterweight 54. Similarly, the second stud 415 at the bottom of the balance plate 44 also needs to be staggered with the counterweight 54 to prevent interference with the movement of the counterweight 54.

[0049] Specifically, traditional equipment is limited to fixed and hanging regular-shaped items such as square boxes and roll labels. Irregularly shaped printed materials or heavy items require a supporting structure for clamping and transport. In this invention, the telescopic module also includes a second bolt 41. Screw holes are provided on both the mounting frame 35 and the connector 4. The second bolt 41 secures the mounting frame 35 and the connector 4, completing the installation of the telescopic module. Alternatively, a locking groove can be provided on the surface of the mounting frame 35 near the lower position of the first electric push rod 36, and then secured with the second bolt 41 and a locking nut. Thus, the telescopic module can be installed at any time while the bidirectional electric push rod 32 adjusts the position of the mounting frame 35. Then, the second stud 415 is passed through the connecting block 43 and the fourth nut 416 is tightened to fix the load-bearing module onto the connecting block 43, as shown in the attached instruction manual. Figure 8 As shown, the support plate 46 can support the items, improve their conveying stability, and reduce the risk of items falling. Both the balance plate 44 and the support plate 46 are provided with mounting grooves 47. When supporting items with a narrow bottom, the drive rod 412 needs to be in a horizontal state. The third bolt 414 is tightened to make it in close contact with the rotating shaft 411 to position the drive rod 412. Alternatively, the rotating shaft 411 can be a self-locking rotating shaft. When the drive rod 412 is in a horizontal state, it can support items with a narrow bottom.

[0050] Furthermore, irregularly shaped items, due to their special shape, may experience a shift in their center of gravity, making them prone to falling during transportation or causing eccentric loads on the first clamping wheel 2 or the second clamping wheel 21. When clamping, the heavier side of the item can be aligned with the guide post 48, and the third bolt 414 can be loosened so that the lower side of the item is in the mounting groove 47. At this time, the drive rod 412 will flip. During the flipping process, the bottom of the drive rod 412 will drive the first rack 51, causing the first rack 51 to drive the gear 52 to rotate, thereby moving the second rack 53. The second rack 53 can then drive the counterweight 54 to move, thus adjusting the center of gravity of the equipment and balancing it. The counterweight 54 can be installed using a weight-adding mode to adapt to different... For items of varying weights and degrees of bias, the first rack 51 and gear 52 are both installed in the mounting slots 47 on the balance plate 44. T-shaped protrusions can be added to the sides of the first rack 51 and second rack 53, and corresponding sliding grooves can be formed on the balance plate 44 for positioning and guiding the first rack 51 and second rack 53. Furthermore, when the lower side of the item is in the mounting slot 47, the square plate 413 clamps the side of the item. Guide posts 48 are fixedly installed on both sides of the mounting slot 47. In conjunction with the guide posts 48, the adjusting block 410 compresses the first spring 49 according to the item's width. This not only adapts to items of different sizes but also provides elastic clamping, achieving clamping of the item from both the top and bottom sides. (See attached instruction manual.) Figure 11As shown; it should be noted that among the irregularly shaped items, there are items with a wide bottom, and the lower part of the item is difficult to fully enter the mounting groove 47. This will cause the mounting groove 47 to only support the bottom, and the drive rod 412 will not rotate fully. In this case, the drive rod 412 can be manually rotated to drive the first rack 51 to achieve center of gravity adjustment, and the third bolt 414 can be tightened or the self-locking shaft can be used to position the drive rod 412.

[0051] Furthermore, for paper-based printed promotional materials weighing less than 200 grams, the device is prone to tearing due to inertia when it jams or stops abruptly. In this invention, the balance plate 44 is changed from a horizontal state to a numerical state, and then it is installed on the connecting block 43 by the second stud 415 and the fourth nut 416. Next, the bracket 45 and the support plate 46 are rotated to make them both vertical, and the fourth bolt 417 is screwed into the balance plate 44 and the support plate 46 through the screw holes to complete the fixing of the shape. In this way, it is changed into a blocking surface, which blocks the stroke caused by inertia when conveying paper-based printed promotional materials weighing less than 200 grams, thereby avoiding the tearing problem.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
