Abstract
Description
Technical Field
[0001] This application relates to the field of packaging equipment technology, and more specifically to telescopic conveyor components, telescopic carton loading machines, and carton opening systems. Background Technology
[0002] With the continuous development of social industrialization, cardboard boxes are widely used in the food industry, paper industry, pharmaceutical industry, and machinery industry. In the cardboard box forming process, the box feeding machine conveys the original cardboard board to the box opening station of the box opening machine, and the box opening machine then opens the original cardboard board to form a standard cardboard box.
[0003] Before the cardboard board is made into a standard cardboard box, when the carton loading machine transports the cardboard board to the carton erecting machine, it usually picks up the cardboard board one by one through the suction and transfer device and places it in the carton placement station of the carton erecting machine. However, in this process, the suction and transfer device needs to lift and lower once and move horizontally back and forth once for each cardboard board it picks up, resulting in low loading efficiency.
[0004] Therefore, how to improve the efficiency of loading boxes is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] In view of this, in order to solve the above-mentioned technical problems, this application provides a telescopic conveyor assembly, a telescopic loading machine, and an unloading system.
[0006] To address the aforementioned technical problems, this application provides a telescopic conveyor assembly, which includes a crossbeam frame, a telescopic crossbeam, a first wheel, a second wheel, a third wheel, a fourth wheel, and a conveyor belt. The third and second wheels are mounted on the telescopic crossbeam, while the first and fourth wheels are mounted on the crossbeam frame.
[0007] The conveyor belt comprises, in sequence and distributed from top to bottom, a cardboard board conveying section, a first return section, an adjustment and reservation section, and a second return section. The cardboard board conveying section is located between the first and second wheels, the first return section is located between the second and third wheels, the adjustment and reservation section is located between the third and fourth wheels, and the second return section is located between the fourth wheel and the first wheel.
[0008] The telescopic crossbeam can extend or retract relative to the crossbeam frame. When the telescopic crossbeam extends relative to the crossbeam frame, the third wheel moves closer to the fourth wheel to supplement the length of the adjustment reserve section needed to extend the length of the carton board conveying section. When the telescopic crossbeam retracts relative to the crossbeam frame, the third wheel moves away from the fourth wheel to retract the length of the adjustment reserve section needed to shorten the length of the carton board conveying section.
[0009] To address the aforementioned technical problems, another technical solution adopted in this application is to provide a telescopic box-loading machine, which includes a first telescopic conveying assembly, a second telescopic conveying assembly, a first drive assembly, and a second drive assembly. Both the first and second telescopic conveying assemblies are the aforementioned telescopic conveying assemblies.
[0010] The first and second telescopic conveyor assemblies are arranged in parallel and at intervals. A first drive assembly is used to drive at least one of the first to fourth wheels of both the first and second telescopic conveyor assemblies to move the conveyor belts in both assemblies. A second drive assembly is used to drive the telescopic beams in both the first and second telescopic conveyor assemblies to extend or retract relative to the corresponding beam frames.
[0011] To address the aforementioned technical problems, another technical solution adopted in this application is to provide a carton opening system, which includes a rope-cutting machine, a telescopic carton loading machine, and a carton opening machine. The telescopic carton loading machine is the aforementioned telescopic carton loading machine, which is used to convey a stack of cardboard boxes to the rope-cutting machine. The stack of cardboard boxes consists of multiple cardboard boxes stacked together and bound with binding ropes.
[0012] The cord-cutting machine cuts the binding cords of the cardboard box stack to release them from the confinement. The carton erector has a box-feeding station, and a telescopic box-feeding machine outputs the cardboard box stack after the cord-cutting machine to the box-feeding station of the carton erector. The carton erector then opens the cardboard boxes in the box-feeding station to form new cartons.
[0013] Beneficial effects: When the telescopic crossbeam extends relative to the crossbeam frame, the cardboard board conveying section can be extended above the box-laying station, allowing it to transport the cardboard board stacks to the top of the box-laying station. When the cable crossbeam retracts relative to the crossbeam frame, the cardboard board conveying section can be shortened to just above the box-laying station, allowing the cardboard board stacks to fall to the box-laying station. Thus, the cardboard board conveying section can transport multiple cardboard boards to the box-laying station in a stacked manner at once, improving box-laying efficiency. Attached Figure Description

[0041] See Figures 1-2 The carton opening system 10 includes a rope cutter 100, a telescopic carton loading machine 200, and a carton opener 300. The telescopic carton loading machine 200 conveys a stack of cardboard prefabricated panels 20 to the rope cutter 100. The stack of cardboard prefabricated panels 20 is composed of multiple stacks of cardboard prefabricated panels 20 and is bound with strapping rope. The rope cutter cuts the strapping rope binding the stack of cardboard prefabricated panels 20 to release the binding rope from the stack. The carton opener 300 has a box placement station. The telescopic carton loading machine 200 outputs the stack of cardboard prefabricated panels 20 after the rope cutter to the box placement station of the carton opener 300. The carton opener 300 opens the cardboard prefabricated panels in the stack of cardboard prefabricated panels 20 placed at the box placement station to form cartons.
[0042] Combination Figures 1-2 See Figures 3-10 The telescopic loading machine 200 includes a telescopic conveying assembly 210, a first drive assembly 220, and a second drive assembly 230.
[0043] The telescopic conveyor assembly 210 includes a crossbeam frame 2101, a telescopic crossbeam 2102, a first wheel 2103, a second wheel 2104, a third wheel 2105, a fourth wheel 2106, and a conveyor belt 2107. Among these, Figure 6 Only a portion of the conveyor belt 2107 is shown in the image. Figures 8-10 The direction of the conveyor belt 2107 is indicated by a line with an arrow. The second wheel 2104 and the third wheel 2105 are set on the telescopic crossbeam 2102, and the first wheel 2103 and the fourth wheel 2106 are set on the crossbeam frame 2101.
[0044] Combination Figures 7-8 See Figures 9-11 As shown, the conveyor belt 2107 sequentially passes through the first wheel 2103, the second wheel 2104, the third wheel 2105, and the fourth wheel 2106 before returning to the first wheel 2103. The conveyor belt 2107 includes a carton board conveying section 31, a first return section 32, an adjustment and reservation section 33, and a second return section 34, which are connected sequentially from top to bottom. The end of the second return section 34 is connected to the beginning of the carton board conveying section 31.
[0045] The cardboard board conveying section 31 is located between the first wheel 2103 and the second wheel 2104, the first return section 32 is located between the second wheel 2104 and the third wheel 2105, the adjustment and reservation section 33 is located between the third wheel 2105 and the fourth wheel 2106, and the second return section 34 is located between the fourth wheel 2106 and the first wheel 2103.
[0046] Combination Figures 1-2 See Figures 3-11 The telescopic crossbeam 2102 can extend or retract relative to the crossbeam frame 2101. When the telescopic crossbeam 2102 extends relative to the crossbeam frame 2101, the third wheel 2105 moves closer to the fourth wheel 2106 to allow the adjusting reserve section 33 to supplement the length that needs to be extended in the carton board conveying section 31. When the telescopic crossbeam 2102 retracts relative to the crossbeam frame 2101, the third wheel 2105 moves away from the fourth wheel 2106 so that the adjusting reserve section 33 can retract the length that needs to be shortened in the carton board conveying section 31.
[0047] The first drive assembly 220 drives at least one of the first wheel 2103 to the fourth wheel 2106 to move the conveyor belt 2107 in the telescopic conveyor assembly 210. The second drive assembly 230 drives the telescopic beam 2102 to extend or retract relative to the beam frame 2101 in the telescopic conveyor assembly 210.
[0048] In this manner, when the telescopic crossbeam 2102 extends relative to the crossbeam frame 2101, the cardboard board conveying section 31 can be extended above the box-laying station, allowing it to transport the cardboard board stack 20 to the top of the box-laying station. When the rope crossbeam retracts relative to the crossbeam frame 2101, the cardboard board conveying section 31 can be shortened to exit above the box-laying station, allowing the cardboard board stack 20 to fall to the box-laying station. Thus, the cardboard board conveying section 31 can transport multiple cardboard boards to the box-laying station at once in the form of a cardboard board stack 20, improving box-laying efficiency.
[0049] Optionally, combined Figure 7 See Figure 8 The telescopic conveyor assembly includes a limiting channel 2117, which is located at the top of the crossbeam 2101 and extends along the length of the crossbeam 2101. The carton board conveying section 31 is slidably disposed within the limiting channel 2117. The limiting channel 2117 is used to guide the carton board conveying section 31 to prevent it from deviating from its original conveying path.
[0050] Optionally, combined Figures 4-8 See Figures 9-11The telescopic beam 2102 is hollow inside, with the first wheel 2103 and the second wheel 2104 located at both ends of the telescopic beam 2102. The cardboard board conveying section 31 extends from the upper edge of the first wheel 2103 to the upper edge of the second wheel. To reduce the volume of the telescopic conveyor assembly 210, the first return section 32 can extend diagonally upwards from the lower edge of the second wheel 2104 through the interior of the telescopic beam 2102 to the upper edge of the third wheel 2105. Furthermore, the adjustment reserve section 33 can extend from the lower edge of the third wheel 2105 to the upper edge of the fourth wheel 2106. The second return section extends from the lower edge of the fourth wheel to the lower edge of the first wheel 2103. It should be understood that this is merely an example, and the specific connection method of the conveyor belt 2107 is not limited to this.
[0051] Furthermore, combined Figures 3-6 See Figures 7-11 The telescopic conveyor assembly 210 includes a guide wheel assembly 2108. The first wheel 2103, the third wheel 2105, and the second wheel 2104 are arranged sequentially along the length of the telescopic beam 2102. The fourth wheel 2106 is located on the side of the third wheel 2105 along the length of the telescopic beam 2102, away from the first wheel 2103. The guide wheel assembly 2108 is located on the side of the third wheel 2105 along the length of the telescopic beam 2102, close to the first wheel 2103 and below the third wheel 2105. The second return section 34, after passing the fourth wheel 2106, is guided by the guide wheel assembly 2108 to the first wheel 2103.
[0052] In this manner, when the telescopic beam 2102 extends relative to the beam frame 2101, the third wheel 2105 can move closer to the fourth wheel 2106, so that the adjusting reserve section 33 can supplement the length that needs to be extended in the carton board conveying section 31. Furthermore, when the telescopic beam 2102 retracts relative to the beam frame 2101, the third wheel 2105 can move away from the fourth wheel 2106, so that the adjusting reserve section 33 can retract the length that needs to be shortened in the carton board conveying section 31.
[0053] Furthermore, since the guide wheel assembly 2108 is located on the side of the third wheel 2105 along the length direction of the telescopic beam 2102, close to the first wheel 2103 and below the third wheel 2105, guiding the second return section 34 via the guide wheel assembly 2108 can prevent the portion of the second return section 34 located between the guide wheel assembly 2108 and the fourth wheel 2106 from contacting the adjustment reserved section 33 or other components between the adjustment reserved section 33 and the second return section 34.
[0054] Optionally, in one example, the first wheel 2103, the second wheel 2104, the third wheel 2105, the fourth wheel 2106, and the guide wheel assembly 2108 are divided into two columns distributed from top to bottom. The first wheel 2103, the third wheel 2105, and the second wheel 2104 are arranged in one column along the length of the telescopic beam 2102. The guide wheel assembly 2108 and the fourth wheel 2106 are arranged in one column along the length of the telescopic beam 2102.
[0055] Alternatively, in another example, the first wheel 2103, the second wheel 2104, the guide wheel set 2108, and the fourth wheel 2106 are divided into two columns distributed from top to bottom. The first wheel 2103 and the second wheel 2104 are in one column and arranged sequentially along the length of the telescopic beam 2102. The third wheel 2105 is offset downward from the column formed by the first wheel 2103 and the second wheel 2104. The guide wheel set 2108 and the fourth wheel 2106 are in one column and arranged sequentially along the length of the telescopic beam 2102.
[0056] Optionally, in another example, the first wheel 2103, the second wheel 2104, the third wheel 2105, the fourth wheel 2106, and the guide wheel assembly 2108 are divided into three columns distributed from top to bottom. The first wheel 2103 and the second wheel 2104 are in one column and arranged sequentially along the length of the telescopic beam 2102. The third wheel 2105 is in another column. The guide wheel assembly 2108 and the fourth wheel 2106 are in another column and arranged sequentially along the length of the telescopic beam 2102. The third wheel 2105 is located below the column formed by the first wheel 2103 and the second wheel 2104, and the fourth wheel 2106 is located below the third wheel 2105.
[0057] Furthermore, combined Figure 4 See Figures 5-6 The side of the crossbeam frame 2101 is provided with a crossbeam clearance groove 41, and the telescopic crossbeam 2102 is movably disposed in the crossbeam clearance groove 41 so that the telescopic crossbeam 2102 can extend or retract relative to the crossbeam frame 2101.
[0058] By employing the above methods, the exposed gap between the telescopic beam 2102 and the beam frame 2101 can be reduced, thereby decreasing the probability of accidental contact with the gap by human hands. Furthermore, the beam frame 2101, through the beam clearance groove 41, covers the telescopic beam 2102, providing a certain degree of dust protection for the telescopic beam 2102.
[0059] Furthermore, combined Figure 7 See Figure 12The telescopic conveying assembly 210 includes a first guide block 2109 and a first guide bar 2110. One of the first guide block 2109 and the first guide bar 2110 is disposed on the inner wall of the crossbeam clearance groove 41, and the other of the first guide block 2109 and the first guide bar 2110 is disposed on the telescopic crossbeam 2102. The first guide block 2109 is provided with a first guide groove 2111, and the first guide bar 2110 is guided and engaged with the first guide groove 2111 to allow the telescopic crossbeam 2102 to extend or retract relative to the crossbeam frame 2101.
[0060] In the above manner, the telescopic beam 2102 can slide relative to the beam frame 2101 to move along the length direction of the telescopic beam 2102, so that the telescopic beam 2102 extends or retracts relative to the beam frame 2101.
[0061] Furthermore, combined Figure 7 See figure - Figure 11 The guide wheel assembly 2108 includes a pressure wheel 2112 and a support wheel 2113. The support wheel 2113, the pressure wheel 2112, and the fourth wheel 2106 are arranged sequentially along the length of the telescopic beam 2102. The support wheel 2113 is located on the side of the pressure wheel 2112 along the length of the telescopic beam 2102, closer to the first wheel 2103.
[0062] The pressing wheel 2112 is used to press down the portion of the second return section 34 located between the fourth wheel 2106 and the pressing wheel 2112, thereby forming a first clearance space 2114 between the second return section 34 and the adjustment reserved section 33. The support wheel 2113 is used to support the portion of the second return section 34 located between the pressing wheel 2112 and the first wheel 2103, thereby forming a second clearance space 2115 below the portion of the second return section 34 located between the support wheel 2113 and the first wheel 2103. In this way, the second return section 34 can avoid other components located in the second clearance space 2115, thereby making full use of the second clearance space 2115 to install other components.
[0063] Optionally, the first wheel 2103, the second wheel 2104, the fourth wheel 2106, and the lower pressure wheel 2112 are sprockets, the third wheel 2105 and the support wheel 2113 are pulleys, and the conveyor belt 2107 is a chain conveyor belt 2107, but is not limited thereto. Furthermore, the telescopic conveyor assembly 210 includes a guide wheel assembly mounting plate 2116, and the guide wheel assembly 2108 can be fixed to the upper and lower side walls of the opening of the crossbeam clearance groove 41 via the guide wheel assembly mounting plate 2116.
[0064] Furthermore, combining 1- Figure 3 See Figures 13-14The telescopic conveyor assembly 210 includes a second guide member 2118, which is disposed at the bottom of the crossbeam frame 2101. The second guide member 2118 is used for sliding engagement with a second guide mating member 2119, which is fixed to a fixed frame (not shown). The telescopic conveyor assembly 210 also includes a locking member (not shown), which is disposed on the crossbeam frame 2101 or other components fixed to the crossbeam frame 2101 and is removably engaged with the fixed frame to prevent the crossbeam frame 2101 from sliding relative to the fixed frame. It should be understood that the fixed frame can be the fixed frame in the rope cutter 100, the fixed frame in the box opener 300, a fixed frame shared by the rope cutter 100, the box opener 300, and the telescopic conveyor assembly 210, or an additional separately provided fixed frame.
[0065] In this manner, when the telescopic conveyor assembly 210 is being maintained or temporarily out of service, the locking member can be pulled out of the fixed frame, allowing the crossbeam frame 2101 to slide relative to the second guide fitting 2119, thereby detaching the telescopic conveyor assembly 210 from the fixed frame. When installing the telescopic conveyor assembly 210 on the fixed frame, the second guide member 2118 can slide along the second guide fitting 2119 into the predetermined installation position, and then the pulled-out locking member can be reinserted into the fixed frame, thus achieving the installation of the telescopic conveyor assembly 210 on the fixed frame. This allows for quick detachment and installation of the telescopic conveyor assembly 210 relative to the fixed frame. Optionally, the locking member can be, but is not limited to, a positioning plunger.
[0066] Furthermore, combined Figures 2-6 See Figures 15-18 The telescopic conveyor assembly 210 is divided into a first telescopic conveyor assembly 210a and a second telescopic conveyor assembly 210b. The first telescopic conveyor assembly 210a and the second telescopic conveyor assembly 210b are arranged in parallel and at intervals. The first drive assembly 220 is used to drive at least one of the first wheel 2103 to the fourth wheel 2106 of both the first telescopic conveyor assembly 210a and the second telescopic conveyor assembly 210b to move the conveyor belt 2107 of both the first telescopic conveyor assembly 210a and the second telescopic conveyor assembly 210b synchronously. The second drive assembly 230 is used to drive the telescopic crossbeam 2102 of both the first telescopic conveyor assembly 210a and the second telescopic conveyor assembly 210b, so that the telescopic crossbeam 2102 of both the first telescopic conveyor assembly 210a and the second telescopic conveyor assembly 210b extends or retracts relative to the corresponding crossbeam frame 2101.
[0067] In the above manner, compared to using a single telescopic conveyor assembly 210 to convey the carton board stack 20, using the parallel first telescopic conveyor assembly 210a and the second telescopic conveyor assembly 210b to jointly convey the carton board stack 20 enables the telescopic loading machine 200 to provide a larger support area for the bottom surface of the carton board stack 20, thereby enabling the conveying of the carton board stack 20 with a larger bottom surface area and good support stability.
[0068] Furthermore, compared to separately and independently providing the first drive component 220 for the first telescopic conveyor component 210a and the second telescopic conveyor component 210b, since the first drive component 220 is used to drive at least one of the first wheel 2103 to the fourth wheel 2106 of the first telescopic conveyor component 210a and the second telescopic conveyor component 210b, the first drive component 220 can be shared by the first telescopic conveyor component 210a and the second telescopic conveyor component 210b, thereby enabling the telescopic loading machine 200 to be miniaturized.
[0069] Furthermore, compared to the separate and independent provision of the second drive component 230 for the first telescopic conveyor component 210a and the second telescopic conveyor component 210b, the second drive component 230 is used to drive the telescopic crossbeam 2102 in both the first telescopic conveyor component 210a and the second telescopic conveyor component 210b together, so that the first telescopic conveyor component 210a and the second telescopic conveyor component 210b can share the second drive component 230, thereby enabling the telescopic loading machine 200 to be miniaturized.
[0070] Furthermore, combined Figures 2-6 See Figures 17-18 The second drive assembly 230 includes a second drive member 61, a timing belt assembly 62, and an adapter 63. The timing belt assembly 62 is disposed between the first telescopic conveyor assembly 210a and the second telescopic conveyor assembly 210b. The adapter 63 is disposed on the timing belt assembly 62 and is connected to the telescopic crossbeam 2102 of the first telescopic conveyor assembly 210a and the telescopic crossbeam 2102 of the second telescopic conveyor assembly 210b, respectively. The second drive member 61 drives the timing belt assembly 62 to drive the adapter 63, thereby causing the telescopic crossbeam 2102 to extend or retract relative to the crossbeam frame 2101. Optionally, the openings of the crossbeam clearance groove 41 of the first telescopic conveyor assembly 210a and the crossbeam clearance groove 41 of the second telescopic conveyor assembly 210b are arranged opposite to each other. This facilitates the adapter 63 connecting to the telescopic crossbeam 2102 through the opening of the crossbeam clearance groove 41.
[0071] Optionally, the first wheel 2103 is a sprocket, the fourth wheel 2106 is a sprocket, and the conveyor belt 2107 is a chain conveyor belt 2107. The first drive assembly 220 includes a first drive member 51, a drive shaft 52, and a connecting shaft 53. The drive shaft 52 is rotatably connected between the crossbeam frame 2101 of the first telescopic conveyor assembly 210a and the crossbeam frame 2101 of the second telescopic conveyor assembly 210b. The first wheel 2103 of the first telescopic conveyor assembly 210a and the first wheel 2103 of the second telescopic conveyor assembly 210b are connected via the drive shaft 52, and the first drive member 51 is used to drive the drive shaft 52 to rotate. The fourth wheel 2106 of the first telescopic conveyor assembly 210a and the fourth wheel 2106 of the second telescopic conveyor assembly 210b are rotatably connected via the connecting shaft 53 between the crossbeam frame 2101 of the first telescopic conveyor assembly 210a and the crossbeam frame 2101 of the second telescopic conveyor assembly 210b.
