Description

Technical Field

[0001] This invention belongs to the field of palletizing system technology, and specifically relates to a palletizing system for printed products. Background Technology

[0002] A palletizing system is an automated device primarily used to stack packaged products into pallets according to a specific arrangement. It is widely used in various industries such as printing, food, beverage, chemical, pharmaceutical, and building materials. When using a palletizing system to palletize printed materials, the packaged printed materials are first tied together, and then conveyed into the palletizing area by a conveyor. Subsequently, a robotic arm or gripper grabs the product according to a preset program and moves it to the designated position. The products are then neatly stacked according to the set pattern (such as staggered, layered, etc.).

[0003] In existing technologies, there are problems with the connection between the flipping process and the first strapping process in the printed matter palletizing system. After the flipping device completes a 180° flip and releases the package, the package is moved to the output conveyor belt and is in a free state. At this time, the packaging paper on the surface of the package (especially the harder kraft paper) is prone to curling up due to the combined effect of gravity and the elastic recovery of the paper itself. This curled edge of the packaging paper is difficult to flatten itself during strapping. In other words, when the packing machine straps it, the curled edge of the packaging paper will cause the strapping tape to shift, making it difficult for the strapping tape to adhere tightly to the surface of the package, resulting in a problem of insecure strapping, which in turn affects the strapping quality and the operational stability of the entire production line. Summary of the Invention

[0004] The purpose of this invention is to provide a printed product palletizing system that, after the printed product package is turned over, presses down the raised edge of the packaging paper before it enters the first bundling stage, thereby avoiding technical problems such as the bundling straps shifting position and the bundling not being secure.

[0005] According to one aspect, to achieve the above objectives, embodiments of the present invention provide a printed article palletizing system, including a book packaging machine, and further comprising: A bag-turning frame, located at the output end of the book packaging machine; The first packing machine, located at the output end of the flipping machine frame, is used to perform the first bundling of printed matter packages; A flipping assembly, which is disposed inside the flipping machine frame, is used to flip the packaged printed materials 180°. A pressing assembly is disposed between the flipping machine frame and the first packing machine, and is used to press down the raised edges of the package after the flipping of the printed package is completed and before the first binding of the printed package is completed; A second packing machine is provided with a first conveying device between the input end of the second packing machine and the output end of the first packing machine, for the second bundling of printed matter packages; A reversing assembly, disposed on the first conveying device, is used to rotate the printed material package by 90°; A palletizing assembly is disposed at the output end of the second packing machine and is used to stack packaged printed materials.

The drive shaft is rotatably mounted on the side of both the input frame and the output frame away from the bag-turning frame; The second motor is installed on both the input frame and the output frame, and the output end of the second motor is fixedly connected to the drive shaft.

[0008] Each of the conveying supports and each of the discharging supports is provided with a conveying structure, which consists of a drive shaft, several support shafts, and a conveyor belt tensioned and fitted outside the drive shaft and several support shafts. The drive shafts located inside the plurality of conveying brackets are arranged coaxially, and the drive shafts located inside the plurality of conveying brackets are all coaxially and fixedly connected to the drive shaft located on the input frame; The drive shafts located inside the plurality of discharge brackets are arranged coaxially, and each drive shaft located inside the plurality of discharge brackets is coaxially and fixedly connected to the drive shaft located on the output frame.

[0009] To secure the printed materials package during the unpacking process, the clamping mechanism includes: The tilting frame has two sliding frames that are symmetrically and slidably arranged inside it. Clamping drive components: Two sets of clamping drive components are symmetrically arranged inside the flipping frame, and the output end of the clamping drive components is fixedly connected to the sliding frame. The rotating cylinder is provided with a fixed clamping frame and a movable clamping frame. The two fixed clamping frames are respectively fixedly installed on both sides of the rotating cylinder, and the two movable clamping frames are respectively fixedly installed on the two sliding frames. In the initial station, one fixed clamping frame and one movable clamping frame are arranged opposite each other to clamp the upper and lower sides of the printed package entering the flipping frame. After the rotating cylinder rotates 180°, another movable clamping frame and another fixed clamping frame switch to an opposite arrangement to support the printed package that has been flipped.

[0010] The fixed clamping frame and the movable clamping frame are each provided with a number of supporting comb teeth, and the number of supporting comb teeth are staggered from the number of conveying brackets and the number of discharging brackets.

[0011] To prevent the printed parcels from curling up before moving to the first packing machine, the packing assembly includes: The mounting frame is disposed between the bag-turning machine frame and the first packing machine; A lifting drive component is fixedly mounted on the top of the mounting frame, and a hanging frame is fixedly mounted on the output end of the lifting drive component; The lower press frame has several lower press frames arranged at equal intervals at the bottom of the suspended frame. Each of the several lower press frames corresponds to a certain number of discharge brackets. Each lower press frame has a pressing bracket slidably arranged inside. Springs are provided between the lower press frame and the material pressing support.

[0012] To adjust the position of the bundled printed materials package, the reversing assembly includes: A reversing frame and a straightening frame are mounted on the first conveying device; A reversing roller, which is rotatably mounted on the reversing frame; A straightening drive component, which is fixedly disposed on one side of the straightening frame; The straightening frame has two clamps symmetrically arranged inside it. One clamp is fixedly arranged inside the straightening frame, and the other clamp is fixedly connected to the output end of the straightening drive.

[0013] To arrange packaged printed materials according to a pre-defined pattern, the palletizing assembly includes: A positioning conveyor, wherein a second conveying device is provided between the input end of the positioning conveyor and the output end of the second packaging machine; The movable baffle and the positioning baffle are provided. The positioning baffle is fixedly installed at one end of the positioning conveyor away from the second conveying device, and the movable baffle is slidably installed on the side of the positioning conveyor.

[0014] Furthermore, a stacking robot is provided on the side of the positioning conveyor away from the movable baffle, and the working end of the stacking robot is provided with a clamping mechanism, which can clamp the packaged printed materials.

[0015] The significant technical effects of the embodiments of the present invention are as follows: 1. The printed product palletizing system provided in this embodiment of the invention, when the printed product package that has been flipped is output from the flipping machine frame and enters the conveyor belt of the discharge bracket, the lifting drive is activated to drive the hanging machine frame to descend, so that the pressing brackets at the bottom of all the pressing machine frames contact the top of the package. At this time, the spring is compressed. During the entire process of the package moving from the flipping machine frame to the first packing machine, the pressing brackets rely on the elastic force of the spring to continuously and stably press the top of the printed product package. The bottom of the package is driven forward by the conveyor belt, and its top slides and cooperates with the smooth bottom surface of the pressing bracket, thereby preventing the edges of the packaging paper of the printed product package from curling up, ensuring that the end face of the package is flat when entering the first packing machine, thereby avoiding the problems of the strapping strap position deviation and loose strapping.

[0016] 2. The printed product palletizing system provided in this embodiment of the invention allows the first motor to drive the rotating drum to rotate 180° after the package is clamped. At this time, the two fixed clamping frames on the rotating drum also rotate. The movable clamping frame, which was originally located at the top, moves to the bottom, and the fixed clamping frame, which was originally located at the bottom, moves to the top. The positions of the fixed clamping frame and the movable clamping frame are interchanged. After the sliding frame is released, the movable clamping frame at the bottom automatically assumes the supporting role. At the same time, the supporting comb teeth on the clamping frame are staggered with the conveyor support and the discharge support to avoid mechanical interference. This structure ensures that the package is reliably fixed or supported before, during, and after flipping, achieving a smooth handover with the conveyor belt before and after flipping and improving the stability of the system operation.

[0027] Please see Figure 1 , Figure 2 This illustration shows a printed product palletizing system according to an embodiment of the present invention, including a book packaging machine 1, a flipping frame 2, a first packing machine 3, a flipping assembly, a pressing assembly, a second packing machine 4, a reversing assembly, and a palletizing assembly. The flipping frame 2 is located at the output end of the book packaging machine 1, and the first packing machine 3 is located at the output end of the flipping frame 2, used for the first bundling of the printed product packages. The flipping assembly is disposed inside the flipping frame 2, used to flip the packaged printed products 180°. The flipping assembly includes a flipping frame 101, a first motor 103, an input frame 104, an output frame 105, a conveying mechanism, and a clamping mechanism 406, as shown below. Figures 3 to 7 As shown, a rotating cylinder 102 is coaxially fixed at the rotation center position of the flipping frame 101. The rotating cylinder 102 is rotatably disposed inside the flipping frame 2. A first motor 103 is fixedly disposed on the flipping frame 2. The output end of the first motor 103 is coaxially fixedly connected to the rotating cylinder 102. An input frame 104 is fixedly disposed between the flipping frame 2 and the output end of the book packaging machine 1. An output frame 105 is fixedly disposed between the flipping frame 2 and the input end of the first packing machine 3. Both the input frame 104 and the output frame 105 are provided with conveying mechanisms for conveying the printed matter packages to be bundled. A clamping mechanism 406 is provided on the flipping frame 101 for fixing the printed matter packages to be bundled.

[0028] It should be noted that in the attached diagram, arrow A indicates the direction of movement of the printed materials package. That is, after the printed materials package is packaged by book packaging machine 1, it undergoes a series of processes including flipping, first packaging, reversal, and second packaging, finally stacking the packaged printed materials neatly. Figure 1 and Figure 2 In the middle section, area B is the loading position for printed materials. Its structure is the same as that of the palletizing assembly. During operation, the complete set of printed materials is first moved to the transfer position, and then the complete set of printed materials is stacked on the designated shelf according to the set pattern. After completion, it is moved to the vicinity of the input end of the book packaging machine 1 by a forklift or other transfer equipment. Then, the complete set of printed materials can be put into the book packaging machine 1 in sequence. After several subsequent steps, the packaging of the printed materials is completed and they are stacked on the designated shelf.

[0029] After the complete set of printed materials is placed on the shelf in area B according to the set pattern, the shelf is transferred to the vicinity of the input end of the book packaging machine 1. At this time, the staff puts the printed materials into the book packaging machine 1 in sequence and uses the book packaging machine 1 to complete the outer packaging operation of the printed materials, outputting a packaged printed material package. After the printed material package is removed from the book packaging machine 1, it enters the flipping frame 2. The conveying mechanism completes the movement of the printed material package in and out. When the printed material package moves into the clamping mechanism 406 on the flipping frame 101, the clamping mechanism 406 is used to fix the printed material package. Then, the first motor 103 is turned on to drive the rotating cylinder 102 to rotate 180°, flipping the printed material package as a whole. After the flipping is completed, the clamping mechanism 406 releases the printed material package, and the printed material package is output from the flipping frame 2.

[0030] During the flipping of the printed package, when the flipping is complete but the clamping of the printed package has not yet been released, the pressing component is activated to press down on the top of the printed package from above. At this time, the clamping of the printed package is slowly released. During this process, the pressing component always maintains contact with the top of the printed package until the printed package falls onto the conveyor mechanism. The pressing component is kept in its current state so that the top of the printed package is always in contact with the pressing component before the first binding.

[0031] The printed package continues to move forward while being pressed until it enters the first packing machine 3. The first packing machine 3 performs the first binding of the printed package. After the first binding is completed, the pressing component is retracted. Subsequently, the printed package enters the reversing component through the first conveyor 5. The reversing component rotates the printed package 90° in place. The rotated printed package enters the second packing machine 4. The second packing machine 4 performs the second binding of the printed package. The binding direction is perpendicular to the first binding direction. The printed package, which has been bound twice, enters the palletizing component through the second conveyor 402. The palletizing component stacks it on the designated shelf according to the preset pattern to complete the work.

[0032] The conveying mechanism includes a conveying bracket 106, a discharge bracket 107, a drive shaft 108, and a second motor 109, such as... Figures 4 to 6 As shown, several conveying supports 106 are evenly spaced on the input frame 104, and several discharging supports 107 are evenly spaced on the output frame 105. A drive shaft 108 is rotatably mounted on the side of both the input frame 104 and the output frame 105 away from the bag-turning frame 2. A second motor 109 is mounted on both the input frame 104 and the output frame 105, and the output end of the second motor 109 is fixedly connected to the drive shaft 108. A conveying structure is provided on each conveying support 106 and each discharging support 107. The conveying structure consists of a drive shaft 110 and several... The system comprises a support shaft 111 and a conveyor belt 112 tensioned and fitted around the drive shaft 110 and the support shaft 111. The drive shafts 110 located inside the several conveyor supports 106 are arranged coaxially. The drive shafts 110 located inside the several conveyor supports 106 are all coaxially and fixedly connected to the drive shaft 108 located on the input frame 104. The drive shafts 110 located inside the several discharge supports 107 are arranged coaxially. The drive shafts 110 located inside the several discharge supports 107 are all coaxially and fixedly connected to the drive shaft 108 located on the output frame 105.

[0033] When the packaged printed materials enter the repackaging frame 2, the second motor 109 on the input frame 104 is turned on. The drive shaft 108 drives the drive shafts 110 in all the conveyor brackets 106 to rotate synchronously. The drive shafts 110 then drive the conveyor belt 112 to rotate, so that the printed materials package on the conveyor belt 112 in the input frame 104 is conveyed in the direction of arrow A.

[0034] After the printed package is flipped, it needs to be moved into the first packaging machine 3. At this time, the printed package is moved to the output frame 105. Then, the second motor 109 on the output frame 105 is turned on, and the drive shaft 108 drives the drive shafts 110 in all the discharge brackets 107 to rotate synchronously. The drive shafts 110 then drive the conveyor belt 112 to rotate, so that the printed package on the conveyor belt 112 in the output frame 105 is conveyed in the direction of arrow A.

[0035] It should be noted that the conveyor belt 112 is arranged in an alternating manner with the subsequent support comb structure to avoid mechanical interference and realize the handover of the package between different workstations.

[0036] The clamping mechanism 406 includes a sliding frame 113, a clamping drive component 114, a fixed clamping frame 115, and a movable clamping frame 116, such as Figure 5 , Figure 7As shown, two sliding frames 113 are symmetrically and slidably arranged inside the tilting frame 101. Two clamping drive units 114 are symmetrically arranged inside each tilting frame 101. The output end of the clamping drive unit 114 is fixedly connected to the sliding frame 113. The clamping drive unit 114 is preferably an electric cylinder. Two fixed clamping frames 115 are respectively fixedly arranged on both sides of the rotating cylinder 102, and two movable clamping frames 116 are respectively fixedly arranged on the two sliding frames 113. In the initial working position, one fixed clamping frame 115 and one movable clamping frame 116 are arranged opposite each other to accommodate the incoming... The printing package is clamped on both the top and bottom sides of the flipping frame 101. After the rotating cylinder 102 rotates 180°, another movable clamping frame 116 and another fixed clamping frame 115 are switched to be set opposite each other to support the printed package after flipping. Both the fixed clamping frame 115 and the movable clamping frame 116 are provided with several support combs. The support combs are staggered with several conveying brackets 106 and several discharge brackets 107 to ensure that the package will not be stuck when clamped and released, and to achieve a smooth handover before and after flipping.

[0037] When the printed package enters the flipping frame 101, the clamping drive 114 at the corresponding position is activated to push the sliding frame 113 to move, thereby moving the movable clamping frame 116 to the fixed clamping frame 115, and the two clamp the printed package from the top and bottom.

[0038] After the package is clamped, the first motor 103 can be turned on to drive the rotating cylinder 102 to rotate 180°. At this time, the two fixed clamping frames 115 on the rotating cylinder 102 also rotate. The movable clamping frame 116, which was originally located at the top, moves to the bottom, and the fixed clamping frame 115, which was originally located at the bottom, moves to the top. The positions of the fixed clamping frame 115 and the movable clamping frame 116 are interchanged.

[0039] At this point, the clamping drive 114 is activated again to release the sliding frame 113. The movable clamping frame 116 located below supports the package. As the movable clamping frame 116 is lowered, the package can be placed on the conveyor belt 112 on the output frame 105, and then the printed package can be moved to the next stage.

[0040] The packing assembly is positioned between the packing frame 2 and the first packing machine 3. It is used to press down any raised edges of the printed material package after it has been turned over and before the first binding of the package. Figure 8As shown, the pressing assembly includes a mounting frame 201, a lifting drive 202, a pressing frame 204, and a spring 206. The mounting frame 201 is positioned between the bag-turning frame 2 and the first packing machine 3. The lifting drive 202 is fixedly mounted on the top of the mounting frame 201. A hanging frame 203 is fixedly mounted at the output end of the lifting drive 202. The lifting drive 202 is preferably an electric cylinder. Several pressing frames 204 are evenly spaced at the bottom of the hanging frame 203. Each pressing frame 204 corresponds to one of several discharge supports 107. A pressing support 205 is slidably mounted inside each pressing frame 204. The bottom of each pressing support 205 is set as a smooth plane, thereby reducing the conveying resistance and not affecting the normal movement of the package. A spring 206 is provided between the pressing frame 204 and the pressing support 205.

[0041] When the printed package that has been flipped is output from the flipping frame 2 and enters the conveyor belt 112 of the discharge bracket 107, the lifting drive 202 is activated to drive the hanging frame 203 to descend, so that the pressing brackets 205 at the bottom of all the pressing frames 204 contact the top of the package. At this time, the spring 206 is compressed. During the entire process of the package moving from the flipping frame 2 to the first packing machine 3, the pressing brackets 205 rely on the elastic force of the spring 206 to continuously and stably press the top of the printed package. The bottom of the package is driven forward by the conveyor belt 112, and its top slides and engages with the smooth bottom surface of the pressing bracket 205, thereby preventing the edges of the packaging paper of the printed package from curling up and ensuring that the end face of the package is flat when entering the first packing machine 3, thereby improving the positional accuracy and binding strength of the strapping.

[0042] A first conveying device 5 is provided between the input end of the second packing machine 4 and the output end of the first packing machine 3 for secondary bundling of printed materials packages. A reversing component is provided on the first conveying device for rotating the printed materials packages by 90°. Figure 9 As shown, the reversing assembly includes a reversing frame 301, a straightening frame 302, a reversing roller 303, a straightening drive 304, and a clamping plate 305. The reversing frame 301 and the straightening frame 302 are mounted on the first conveying device 5. The reversing roller 303 is rotatably mounted on the reversing frame 301. The straightening drive 304 is fixedly disposed on one side of the straightening frame 302. The straightening drive 304 is preferably an electric cylinder. Two clamping plates 305 are symmetrically arranged inside the straightening frame 302. One clamping plate 305 is fixedly disposed inside the straightening frame 302, and the other clamping plate 305 is fixedly connected to the output end of the straightening drive 304.

[0043] After the printed package is first bundled, it moves to the second packing machine 4 under the operation of the first conveyor 5. During this process, the printed package first contacts the reversing roller 303, which uses friction to rotate the package 90° in place. Then, the printed package enters the straightening frame 302. At this time, the straightening drive 304 is activated to push the corresponding clamping plate 305 to move to another clamping plate 305. The two clamping plates 305 clamp the package from both sides and adjust it to a state that is completely perpendicular to the conveying direction. This makes it easier to use the second packing machine 4 to perform a second bundled strapping that is perpendicular to the first bundled strapping, thus forming a cross-shaped strapping band and increasing the strength of the packaging.

[0044] The palletizing assembly is located at the output end of the second packaging machine 4 and is used to stack the packaged printed materials. The palletizing assembly includes a positioning conveyor 401, a movable baffle 403, and a positioning baffle 404. Figure 10 As shown, a second conveying device 402 is provided between the input end of the positioning conveyor 401 and the output end of the second packaging machine 4. A positioning baffle 404 is fixedly provided at the end of the positioning conveyor 401 away from the second conveying device 402. A movable baffle 403 is slidably provided on the side of the positioning conveyor 401. A stacking robot 405 is provided on the side of the positioning conveyor 401 away from the movable baffle 403. A clamping mechanism 406 is provided at the working end of the stacking robot 405, which can clamp the packaged printed materials.

[0045] After the bundled printed materials package enters the positioning conveyor 401 through the second conveyor 402, it moves until it touches the positioning baffle 404. At this point, the printed materials package stops moving forward. Then, the movable baffle 403 is pushed from the side of the printed materials package to the clamping position of the clamping mechanism 406. Then, the clamping mechanism 406 is activated to clamp the printed materials package, lifts it up, and stacks it on the designated shelf according to the preset stacking pattern.

[0046] After the complete set of printed materials is placed on the shelf in area B according to the set pattern, the shelf is transferred to the vicinity of the input end of the book packaging machine 1. At this time, the staff put the printed materials into the book packaging machine 1 in sequence and use the book packaging machine 1 to complete the outer packaging operation of the printed materials, outputting a packaged printed material package. After the printed material package is removed from the book packaging machine 1, it enters the repackaging frame 2. At this time, the second motor 109 on the input frame 104 is turned on, which drives the drive shaft 108 to drive the drive shaft 110 in all the conveyor brackets 106 to rotate synchronously. The drive shaft 110 then drives the conveyor belt 112 to rotate, so that the printed material package on the conveyor belt 112 in the input frame 104 is conveyed in the direction of the arrow A.

[0047] Once the printed package is clamped, the clamping drive 114 at the corresponding position is activated to move the sliding frame 113, thereby moving the movable clamping frame 116 towards the fixed clamping frame 115. The two clamp the printed package from both the top and bottom. After clamping the package, the first motor 103 is activated to drive the rotating drum 102 to rotate 180°. At this time, the two fixed clamping frames 115 on the rotating drum 102 also rotate. The movable clamping frame 116, which was originally located at the top, moves to the bottom, and the fixed clamping frame 115, which was originally located at the bottom, moves to the top. The positions of the fixed clamping frame 115 and the movable clamping frame 116 are interchanged. Then, the clamping drive 114 is activated again to release the sliding frame 113. The movable clamping frame 116, which is located at the bottom, then supports the package. As the movable clamping frame 116 is lowered, the package can be placed on the conveyor belt 112 on the output frame 105, and then the printed package can be moved to the next stage.

[0048] When the printed package that has been flipped is output from the flipping frame 2 and enters the conveyor belt 112 of the discharge bracket 107, the lifting drive 202 is activated during this process, causing the hanging frame 203 to descend, so that the pressing brackets 205 at the bottom of all the pressing frames 204 contact the top of the package. At this time, the spring 206 is compressed. Then, the second motor 109 on the output frame 105 is activated, which drives the drive shaft 108 to drive the drive shafts 110 in all the discharge brackets 107 to rotate synchronously. The drive shafts 110 then drive the conveyor belt 112 to move. The rotation causes the printed packages on the conveyor belt 112 entering the output frame 105 to be conveyed in the direction of arrow A. During this process, the pressure bracket 205 continuously and stably presses down on the top of the printed package by the elastic force of the spring 206. The bottom of the package is driven forward by the conveyor belt 112, while its top slides against the smooth bottom surface of the pressure bracket 205, thereby preventing the edges of the packaging paper of the printed package from curling up and ensuring that the end face of the package is flat when entering the first packing machine 3, thus improving the positional accuracy and binding strength of the strapping.

[0049] The printed package continues to move forward while being pressed down until it enters the first packaging machine 3. The first packaging machine 3 performs the first binding of the printed package. After the first binding is completed, the lifting drive 202 is retracted. After the first binding is completed, the printed package moves to the second packaging machine 4 under the operation of the first conveying device 5. During this process, the printed package first contacts the reversing roller 303. The reversing roller 303 uses friction to make the package rotate 90° in place. Then, the printed package enters the straightening frame 302. At this time, the straightening drive 304 is activated to push the corresponding clamping plate 305 to move to another clamping plate 305. The two clamping plates 305 clamp the package from both sides and adjust it to a state that is completely perpendicular to the conveying direction. Then, it enters the second packaging machine 4. The second packaging machine 4 performs the second binding of the printed package. The binding direction is perpendicular to the first binding direction. The printed package that has completed the two bindings enters the positioning conveyor 401 through the second conveying device 402.

[0050] As the printed package moves, it stops moving forward when it touches the positioning baffle 404. Then, the movable baffle 403 is pushed from the side of the printed package to the clamping position of the clamping mechanism 406. The clamping mechanism 406 is then activated to clamp the printed package, which is then lifted and stacked on the designated shelf according to the preset stacking pattern.
