The film-tearing support platform adsorbs and positions the product that needs to be peeled.

[0014] Furthermore, the film-tearing mechanism also includes a film-tearing assembly disposed above the other end of the film-tearing linear guide rail. The film-tearing assembly includes a film-tearing mounting side plate, on which are mounted a film-tearing rubber wheel, a film-tearing guide roller, a longitudinally moving lifting film-tearing wheel, and a film-tearing belt arranged around the film-tearing rubber wheel, the film-tearing guide roller, and the longitudinally moving lifting film-tearing wheel, respectively.

[0059] The present invention will now be described in detail with reference to the accompanying drawings.

[0060] like Figure 1-9As shown, a product reversing machine includes a device platform 1, which is provided with a feeding mechanism 10 and a discharging mechanism 9. A first processing platform 101 and a second processing platform 102 are provided between the feeding mechanism 10 and the discharging mechanism 9. Both the first processing platform 101 and the second processing platform 102 include a reversing mechanism 5 and a pressure holding mechanism 8.

[0061] The feeding mechanism 10 includes a horizontally arranged feeding line 12, the feeding line 12 is equipped with a feeding gantry 13, the feeding gantry 13 is equipped with a feeding positioning plate 14 that can move along the width direction of the feeding line 12; the feeding gantry 13 is equipped with a transverse telescopic cylinder 15 arranged perpendicular to the product forward direction, the transverse telescopic cylinder 15 drives the feeding positioning plate 14 to move the product closer to the clamping point, which facilitates the accuracy of subsequent feeding.

[0062] A flipping platform 11 is provided on the side of the feeding line 12. The flipping platform 11 is equipped with a rotating component that can rotate laterally. The drive end of the rotating component is equipped with a feeding suction cup that can pick up the product of the feeding line 12. The rotating component located on the flipping platform 11 picks up the product through the feeding suction cup. Then the rotating component rotates 180 degrees so that the bottom surface of the product faces upwards for transfer to the next process.

[0063] Preferably, the rotating component is a first lifting cylinder 16 installed on the flipping platform 11. A first rotary cylinder 17 is installed on the driving end of the first lifting cylinder 16. An infeed suction rack 18 is installed on the driving end of the first rotary cylinder 17. The infeed suction cup component consists of multiple first suction cups 19 arranged on the infeed suction rack 18. Under the drive of the first lifting cylinder 16, the first suction cups 19 can adsorb the products located on the infeed line 12. Then, under the drive of the first rotary cylinder 17, the bottom surface of the products is turned upwards for transfer to the next process.

[0064] The feeding mechanism 10 also includes a transfer gantry 2 located above the feeding line 12. The transfer gantry 2 has two transfer linear guides 21 arranged along its length, one of which is arranged laterally to the left, and the other laterally to the right. A feeding transfer seat 22 is slidably mounted on the transfer linear guide 21. The feeding transfer seat 22 is equipped with a first loading robot 23 and a second loading robot 24 capable of longitudinally moving and adsorbing the product. The first loading robot 23 and the second loading robot 24 are arranged laterally at intervals. The first loading robot 23 can adsorb the flipped product and transfer it to the next process for film removal.

[0065] Preferably, the first feeding robot 23 includes a first feeding linear guide 25 longitudinally mounted on the feeding transfer seat 22, a feeding drive seat 26 slidably mounted on the first feeding linear guide 25, a first feeding rotary cylinder 27 mounted on the feeding drive seat 26, a first transfer adsorption frame 28 mounted on the drive end of the first feeding rotary cylinder 27, and the first transfer adsorption frame 28 is provided with a plurality of second suction cups for adsorbing products.

[0066] Preferably, the second loading robot 24 has a similar function to the first loading robot 23, except that the transfer adsorption frame only moves in the vertical direction.

[0067] The transfer gantry 2 is equipped with a film-tearing mechanism 3 along the direction of travel. The film-tearing mechanism 3 includes a film-tearing linear guide rail 31, a film-tearing base 32 is slidably mounted on the film-tearing linear guide rail 31, and a film-tearing support platform that can slide perpendicular to the film-tearing linear guide rail 31 is mounted on the film-tearing base 32. The film-tearing support platform adsorbs and positions the product that needs to be peeled.

[0068] In this embodiment, the product transferred by the first feeding robot 23 enters the film-tearing mechanism 3, the product is transferred to the film-tearing support table, and the product is adsorbed onto the film-tearing support table by a suction cup, and then the film-tearing operation is performed.

[0069] The film-tearing mechanism 3 also includes a film-tearing assembly 33 disposed above the other end of the film-tearing linear guide rail 31. The film-tearing assembly 33 includes a film-tearing mounting side plate 34. The film-tearing mounting side plate 34 is equipped with a film-tearing rubber wheel 35, a film-tearing guide roller 36, a longitudinally moving lifting film-tearing wheel 37, and a film-tearing belt 45 arranged around the film-tearing rubber wheel 35, the film-tearing guide roller 36, and the longitudinally moving lifting film-tearing wheel 37. The lifting film-tearing wheel 37 is located at the bottom of the film-tearing mounting side plate 34. The servo motor drives the film-tearing guide roller 36 to rotate, and the film-tearing belt 45 moves accordingly.

[0070] After positioning, the product slides along the film-tearing linear guide rail 31 to the top of the film-tearing assembly 33 via the film-tearing support platform. The film-tearing belt 45 moves under the drive of the film-tearing rubber wheel 35, the film-tearing guide roller 36, and the longitudinally moving lifting film-tearing wheel 37. The lifting film-tearing wheel 37 descends to contact the film of the product with the film-tearing belt 45. The film-tearing belt 45 and the film make frictional contact and peel off the protective film of the product, completing the film-tearing process, which facilitates subsequent folding.

[0071] Preferably, the film-tearing mounting side plate 34 is also equipped with a plurality of spaced tensioning rollers 4 and a tensioning guide rail 41 for mounting one of the tensioning rollers 4. The film-tearing belt 45 is also arranged around the tensioning rollers 4. A tensioning support seat 42 is slidably mounted on the tensioning guide rail 41. The tensioning roller 4 is rotatably mounted on the tensioning support seat 42. The film-tearing mounting side plate 34 is equipped with a tension telescopic cylinder 43. The tension telescopic cylinder 43 telescopically drives the tensioning support seat 42 to slide along the tensioning guide rail 41, so that the tension of the film-tearing belt 45 around the tensioning guide rail 41 can be adjusted.

[0072] Preferably, to prevent the friction belt from carrying the product away when the film is being peeled off, a pressing stop block 44 is installed at the bottom that can move up and down to press down a part of the product. Driven by the lifting cylinder, the pressing stop block 44 can hold the area where the film does not need to be peeled off, and the friction belt contacts the protective film to peel off the protective film of the product, thus completing the film peeling.

[0073] After the film is torn off, the film-tearing support platform slides along the film-tearing linear guide rail 31 and approaches to the bottom of the transfer gantry 2. The second loading robot 24 moves to a position directly above the film-tearing support platform and uses the second loading robot 24 to adsorb and transfer the film-tearing product to the folding mechanism 5 for folding operation.

[0074] The folding mechanism 5 includes a folding platform 51 for positioning the product and a folding mechanism 6 for folding the product. The folding platform 51 is provided with a folding positioning structure 52 that can adjust the positioning size. The folding positioning structure 52 includes a positioning suction cup 58 that can adsorb the product onto the folding platform 51. The product is fixed on the folding platform 51 by the positioning suction cup 58 and the folding positioning structure 52.

[0075] Preferably, there are multiple positioning suction cups 58, which are evenly arranged on the folding table 51.

[0076] The folding mechanism 6 includes a rotatable rotating shaft 65, a folding arm 66 vertically mounted on the rotating shaft 65, a first folding strip 7 vertically mounted on the folding arm 66 with adjustable position along the length direction, a second folding strip 71 vertically mounted on the first folding strip 7 with adjustable position along the length direction, and two or more folding suction cups 76 mounted on the second folding strip 71 to attract the part of the product that needs to be folded.

[0077] After the product that needs to be folded enters the first processing platform 101 or the second processing platform 102, the positioning suction cup 58 of the folding table 51 will adsorb the area that does not need to be folded. The first folding bar 7 of the folding mechanism 6 can be adjusted to a horizontal position, which will drive the folding suction cup 76 installed on the second folding bar 71 to adsorb the area of ​​the product that needs to be folded. Both parts of the product are adsorbed. Then the rotating shaft 65 rotates to fold the folded area back to fit the area that does not need to be folded. During the folding process, the product is adsorbed and positioned and will not lift up, which can improve the alignment after folding and result in better quality.

[0078] Preferably, the folding positioning structure 52 includes a positioning groove 53 arranged along the width direction of the folding table 51. A side positioning block 54 for positioning the side of the product is slidably installed in the positioning groove 53. The position of the side positioning block 54 can be adjusted according to the width of the product. When the product is placed on the folding table 51, the side of the product can be positioned by the side positioning block 54, so that it is not easy to tilt or shift during subsequent folding operations.

[0079] Furthermore, a folding extension platform 55 is installed at one corner of the folding platform 51. The folding extension platform 55 is equipped with an L-shaped strip 56 that moves along the diagonal length of the folding platform 51. The L-shaped strip 56 can position one corner of the product. Driven by the positioning telescopic cylinder 57, the L-shaped strip 56 moves along the diagonal length of the folding platform 51, so that one corner of the product located on the folding platform 51 abuts against the side positioning block 54, and the other diagonally opposite corner of the product is positioned by the L-shaped strip 56, thus positioning the product.

[0080] Preferably, the folding base plate 61 is equipped with a first support platform 50 for mounting the folding stage 51 and a folding linear guide rail 62 located beside the first support platform 50. The folding linear guide rail 62 is parallel to the pressure-holding linear guide rail 81. A vertically arranged folding telescopic cylinder 63 is slidably mounted on the folding linear guide rail 62. A folding rotary cylinder 64 is mounted on the drive end of the folding telescopic cylinder 63, and a rotating shaft 65 is mounted on the folding rotary cylinder 64. In this embodiment, before the product is folded, the folding telescopic cylinder 63 slides along the folding linear guide rail 62, away from the folding table 51. After the product is positioned, the folding telescopic cylinder 63 slides along the folding linear guide rail 62 closer to the folding table 51. Then, the folding telescopic cylinder 63 extends, driving the folding rotary cylinder 64 closer to the folding table 51. The first folding bar 7 can adjust its lateral position, driving the folding suction cup 76 installed on the second folding bar 71 to suction the area of ​​the product that needs to be folded. Both parts of the product are suctioned. Then, the rotating shaft 65 rotates, folding the folded area back to fit the area that does not need to be folded. During the folding process, the product is suctioned and positioned, and will not lift up, which can improve the alignment after folding and result in better quality.

[0081] Specifically, one end of the folding arm 66 is formed with a nesting hole 77 that nests into the rotating shaft 65, and one end of the folding arm 66 is fixed to the rotating shaft 65 through the nesting hole 77. The folding arm 66 has a first long groove 72 formed along its length. One end of the first folding strip 7 has a first connecting hole 73 that coaxially engages with the first long groove 72. The first folding strip 7 has a second long groove 74 formed along its length. One end of the second folding strip 71 has a second connecting hole 75 that coaxially engages with the second long groove 74. The folding suction cup 76 can be two suction holes formed in the second folding strip 71. In this embodiment, the first folding strip 7 is fixed to the folding arm 66 by inserting a screw into the first long groove 72 through the first connecting hole 73. Similarly, the second folding strip 71 is fixed to the first folding strip 7 by inserting a screw into the second long groove 74 through the second connecting hole 75. This allows for adjustment of the positions of the first folding arm 66 and the second folding arm 66, enabling reverse folding of products of different sizes.

[0082] The pressure holding mechanism 8 includes a pressure holding platform 86 that can move longitudinally; the pressure holding mechanism 8 also includes a pressure holding linear guide rail 81, and a folding bottom plate 61 is slidably mounted on the pressure holding linear guide rail 81. The folding bottom plate 61 can slide along the length direction of the pressure holding linear guide rail 81. The folded product moves to the pressure holding platform 86 through the pressure holding linear guide rail 81. The pressure holding platform 86 applies pressure to the folded product to further increase the bonding stability after folding and further improve the product quality.

[0083] Preferably, the pressure holding mechanism 8 further includes a pressure holding column 82 arranged on the equipment platform 1. A horizontally arranged pressure holding drive seat 83 is installed on the top of the pressure holding column 82. A longitudinally arranged pressure holding telescopic cylinder 84 is installed on the pressure holding drive seat 83. A pressure holding platform 86 is installed on the drive end of the pressure holding telescopic cylinder 84. A pressure holding fixing plate 85 is installed on the drive end of the pressure holding telescopic cylinder 84. The bottom surface of the pressure holding fixing plate 85 is attached and fixedly connected to the pressure holding platform 86, so that the pressure holding platform 86 remains horizontal. The pressure holding telescopic cylinder 84 extends and drives the pressure holding platform 86 to press down to press the folded product together, thereby improving its fit.

[0084] The unloading mechanism 9 includes an unloading gantry 91 arranged on the equipment platform 1. A feeding linear guide 92 is arranged along the length of the unloading gantry 91. An unloading drive seat 93 is slidably mounted on the feeding linear guide 92, and an unloading robot 94 is mounted on the unloading drive seat 93. The unloading robot 94 can slide along the feeding linear guide 92 via the unloading drive seat 93 to directly above the outer end of one of the pressure-holding linear guides 81, and can transfer and unload the folded and pressure-holding product.

[0085] Preferably, the unloading robot 94 includes an unloading linear guide 95 arranged longitudinally along the length of the unloading drive base 93. An unloading mounting base 96 is mounted on the unloading linear guide 95, and an unloading rotary cylinder 97 is mounted on the unloading mounting base 96. An unloading suction frame 98 is mounted on the drive end of the unloading rotary cylinder 97, and the unloading suction frame 98 is equipped with multiple unloading suction cups 99 for adsorbing the product. After the unloading robot 94 is transferred to a position directly above the product via the unloading suction frame 98, it descends and adsorbs the product via the unloading suction cups 99. Then, it rotates to a suitable angle and moves along the unloading linear guide 92 to unload the product.

[0086] Preferably, a discharge assembly line 90 is provided below the discharge gantry 91. The discharge assembly line 90 and the infeed assembly line 12 are horizontally aligned. A first processing platform 101 is arranged on one side of the discharge assembly line 90 and the infeed assembly line 12, and a second processing platform 102 is arranged on the other side. The two processing platforms simultaneously perform film tearing, folding and pressure holding on the product. Then, the product is transferred together to the discharge assembly line 90 by the discharge robot 94 for outward conveying and unloading.

[0087] Preferably, the discharge gantry 91 and the transfer gantry 2 are arranged in parallel and spaced apart, and the discharge gantry 91 and the transfer gantry 2 have the same length, making the structural layout of the equipment platform 1 more reasonable.

[0088] In addition, the discharge line 90 is equipped with a coding gantry, which has longitudinally arranged coding terminals. The coding terminals perform coding operations on the folded products to mark them.
