Abstract
Description
Technical Field
[0001] The invention relates to the technical field of printing consumables manufacturing, and in particular to a rewinding and shaping machine for a printing consumables tape box. Background Art
[0002] In the automated production of printing consumables tape cassettes, after the carbon ribbon is rewound by the rewinder, it is necessary to shape the carbon ribbon by a shaping machine before loading it into the tape cassette to ensure that the carbon ribbon conforms to the tape track in the tape cassette when it is loaded into the tape cassette.
[0003] An existing carbon ribbon shaping machine includes an unwinding shaft holding device, a rewinding shaft holding device and a bending position guide rod group, and each guide rod in the bending position guide rod group can be moved from its own starting position to its own corresponding bending position. The carbon ribbon that has been rewound has an extension section involved between the unwinding shaft and the rewinding shaft. After the carbon ribbon that has been rewound is transferred to the carbon ribbon shaping device, the unwinding shaft and the rewinding shaft of the carbon ribbon are first matched to the unwinding shaft holding device and the rewinding shaft holding device respectively, and at this time, multiple guide rods are located in the same plane of the carbon ribbon. Subsequently, the guide rods are all moved from their own starting positions to their own corresponding bending positions. During the process, the extension sections of the carbon ribbon are pulled by each guide rod and moved to each bending position. Finally, the extension sections of the carbon ribbon conform to the tape running track in the tape box. The carbon ribbon that has been shaped is placed in the tape box and the carbon ribbon correctly falls within the preset track position in the tape box.
[0004] This type of ribbon shaping machine shapes the ribbon based on the fact that the ribbon has an unwinding shaft and a rewinding shaft. The situation is different for the printing paper roll in the ribbon box together with the ribbon. The printing paper roll in the ribbon box will be taken out of the ribbon box after printing. That is, the printing paper roll is only wound on the unwinding shaft and has a free lead-out section and tends to be loose. Not only is it difficult to transfer from the rewinding machine to the shaping machine, but also because there is no rewinding shaft, it cannot be shaped by the existing shaping machine. Summary of the invention
[0005] The main purpose of the present invention is to provide a rewinding and shaping machine for printing consumable paper rolls, which can complete rewinding and shaping at the same workstation, reduce the difficulty of automated rewinding and shaping, and improve the efficiency of paper roll rewinding and tape box assembly.
[0006] The rewinding and shaping machine provided by the present invention comprises a shaping device, the shaping device comprises a reel mechanism and a first guiding rod mechanism, the reel mechanism is provided with a first belt winding position located on a first plane, the first plane is perpendicular to the first axis of the reel mechanism, the first guiding rod mechanism comprises a first rod group coplanar with the first belt winding position, the first rod group can move in an axial plane perpendicular to the first axis; the rewinding and shaping machine also comprises a rewinding device, the rewinding device comprises a guiding wheel group, the rewinding device and the shaping device share the reel mechanism; the first rod group is arranged along a first trajectory, the first rod group can translate from the first position to the second position in the first plane, the first position Located between the guide wheel group and the first tape roll position, the first rod group can move axially along the first axis and leave the first plane; the rewinding device also includes a second guide rod mechanism and a compression mechanism; the second guide rod mechanism includes a second rod group arranged along a second trajectory, the rod extension directions between the second rod group and the second rod group are opposite, and the second rod group can move axially to the second position; the compression mechanism includes a profiling member, and the profiling member can move in the first plane to a third position opposite to the second position; a shaping position is formed between the first rod group located at the second position and the profiling member located at the third position, and the first rod group and the second rod group can exchange paper tape at the second position.
[0007] It can be seen from the above scheme that in order to solve the problem of transfer difficulty in the process of rewinding, transferring and reshaping the paper roll, the present invention first considers combining the rewinding and shaping of the paper roll in the same workstation. Such a setting can avoid transfer. After the rewinding is completed at the first belt roll position of the reel mechanism, the paper tape of the paper roll has not been cut yet and is tensioned by the guide wheel group. At this time, the first guide rod mechanism is controlled to move axially to the first plane, and then the first rod group is controlled to move horizontally from the first position to the second position, and the paper tape is pulled and guided to deform in the process; then the profiling member moves to the third position and squeezes the paper tape in the shaping position from both sides with the first rod group in the second position to achieve primary shaping. Then the first rod group and the second rod group are connected axially to hand over the paper tape to the second rod group and the second rod group performs secondary shaping. Among them, when the first rod group shapes the paper tape, in fact all the first rods are located on one side of the paper tape, and can only perform outward support shaping but cannot complete inward bending shaping. Although the profiling member can force the paper tape to move inside and outside, the profiling block and its horizontally arranged driving unit hinder the box loading; therefore, the profiling member presses from the outside to the inside to keep the paper tape in the inward bending state, and then the second rod group is axially inserted and extended to both sides of the paper tape to keep the paper tape in the inward bending trend. Subsequently, the shaped paper tape can be easily loaded into the tape box.
[0008] A further solution is that the profiling member includes a convex portion, on which a concave portion is arranged; when the profiling member is located at the third position, the convex portion protrudes toward the second position and the concave portion is recessed away from the second position; when the profiling member is located at the third position and when the first rod group is located at the second position, the first rod group is located outside the concave portion; when the profiling member is located at the third position and when the first rod group is located at the second position, a second guide rod in the second rod group is located in the concave portion.
[0009] As can be seen from the above, since the profiling member is provided with a convex portion that can force the paper tape to bend inward, and the convex portion is provided with a concave position, a position for the second rod to be inserted is formed between the outer side of the paper tape that is forced to bend inward and stretched straight and the concave position. By utilizing this position, after the second rod group arranged along the fixed track hands over the paper tape, at least one second guide rod of the second rod group can reach the outside of the paper tape to keep the paper tape in an inward bending state before boxing, thereby meeting the shaping requirements.
[0010] A further solution is that the first rod group includes multiple first guide rods, at least one first guide rod is arranged to float along the axial direction, and / or at least one first guide rod can be rotatable around its own axis; during the process of docking the belt between the first rod group and the second rod group at the second position, the second rod group forces the first guide rod to float and tend to leave the first plane.
[0011] As can be seen from the above, in order to avoid interference between the first rod and the second rod located at the same position and the inability to complete the handover when docking, the present invention also arranges the first rod to be axially floating, and when the second rod enters the first plane axially, the first rod is forced to leave the first plane, thereby avoiding interference and achieving paper tape handover at the same time.
[0012] Another further solution is that the rewinding and shaping machine includes a driving mechanism, which includes a rotation drive unit, a track assembly, a dual-axis module and a moving part; the track assembly includes a track part and a swinging part, and the track part is provided with a track groove, and the plane where the track groove is located is parallel to the first plane; under the drive of the rotation drive unit, the swinging part can swing around the third axis; the track groove is located on the outer periphery of the third axis, and a linear hole is provided on the swinging part which penetrates axially and is connected to the track groove; the dual-axis module includes a movable end, the moving part and the first guide rod mechanism are both connected to the movable end, and the moving part is located in the linear hole and in the track groove.
[0013] As can be seen from the above, the first rod group needs to translate from the first position from the periphery of the first axis to the second position, and its moving path will be restricted by other devices arranged nearby, and the special trajectory that is not a straight line or a circular arc cannot be achieved by a simple linear drive unit or a rotation drive unit. To this end, the present invention designs a driving mechanism, when the rotation drive unit drives the swinging member to swing, the moving member is forced to move along the trajectory of the trajectory groove, and the first guide rod mechanism also moves with the moving member, so that the first rod group translates along the special trajectory, solving the problem of limited trajectory path.
[0014] Another further solution is that the reel mechanism includes a winding shaft that can rotate around a first axis, the winding shaft includes two half shafts that are spaced apart on both sides of the first axis, and the two half shafts can move axially and leave the first tape roll position; the rewinding device also includes a first clamping mechanism and a tape cutting mechanism; the first clamping mechanism includes a first clamping portion, the first clamping portion can move from a fourth position in a first plane and pass through the first tape roll position, the fourth position is between the guide wheel group and the first tape roll position; the tape cutting mechanism can move to a fifth position in the first plane, and the fifth position is between the fourth position and the first tape roll position.
[0015] As can be seen from the above, the reel mechanism is used for rewinding a coreless paper roll.
[0016] A further solution is that the rewinding device also includes a tightening mechanism that can rotate around the second axis, the tightening mechanism includes an inner support member and an outer clamping member, a pair of inner support members are respectively arranged on both sides of the second axis at intervals, and a pair of outer clamping members are respectively arranged on both sides of the second axis at intervals, the inner support member is located on the inner periphery of the outer clamping member, and a second belt roll position is formed between the inner support member and the outer clamping member, and both the inner support member and the outer clamping member can move and change the distance from the second axis; the tightening mechanism can move and make the first belt roll position coincide with the second belt roll position.
[0017] As can be seen from the above, since one end of the paper tape led out of the paper roll is free and the paper roll has no core, the positioning of the two semi-axes alone cannot prevent the paper roll from loosening. If the secondary shaping does not process the paper roll, the paper roll will be loose and cannot achieve the shaping effect. For this reason, the present invention also provides a tightening mechanism. When the second rod group is docked with the first rod group, the first axis coincides with the second axis, and the tightening mechanism is also docked with the two semi-axes. After the paper roll is handed over, it is located in the second roll position between the inner support member and the outer clamp of the tightening mechanism. At this time, the inner support member and the outer clamp are controlled to move to narrow the second roll position, so that the paper roll can be supported from the inside and clamped from the outside to prevent the paper roll from loosening. Then, the tightening mechanism is controlled to reverse in the opposite direction of the rewinding direction around the second axis to tighten the paper tape and make the paper tape further fit the track. This setting improves the shaping effect for coreless paper rolls.
[0018] A further solution is that the tightening mechanism includes a linear drive unit and a forcing member, the linear drive unit drives the forcing member to move axially along the second axis; the forcing member and the inner support member are transmitted via a first wedge surface structure, and the axial movement of the forcing member along the second axis can force the inner support member to move radially along the second axis; and / or the forcing member and the outer clamp are transmitted via a second wedge surface structure, and the axial movement of the forcing member along the second axis can force the outer clamp to move radially along the second axis.
[0019] As can be seen from the above, under this arrangement, the planar translation of the inner support member and the outer clamping member can be achieved through a rotation drive unit, and the wedge surface structure has a good locking effect to ensure the clamping effect of the paper roll.
[0020] A further solution is that the shaping device also includes a second clamping mechanism, the second clamping mechanism includes a second clamping part, the second rod group and the second clamping part are arranged in sequence along the belt path; the second clamping part can be moved to a sixth position, the sixth position is located in the first plane, and the fifth position is located between the fourth position and the sixth position.
[0021] As can be seen from the above, the second clamping mechanism cooperates with the first clamping mechanism to clamp the paper tape from both sides of the cutting position to prevent the paper roll from loosening after being cut. Among them, the first clamping mechanism simultaneously takes into account the dual functions of rewinding and feeding the tape and cutting and clamping the tape.
[0022] A further solution is that the tightening mechanism of the rewinding device, the second guide rod mechanism of the shaping device and the second clamping mechanism are integrated into the same robot; when the first belt roll position coincides with the second belt roll position, the first rod group and the second rod group dock the belt at the second position, and the second clamping part reaches the sixth position.
[0023] As can be seen from the above, under this setting, after the manipulator moves, the tightening mechanism and the second guide rod mechanism can reach the corresponding docking positions at the same time, and the second clamping mechanism can also reach the sixth position. The automation integration is high, and the investment in the drive unit is reduced to reduce costs and reduce the difficulty of control.
[0024] A further solution is that the manipulator includes a third connecting seat and a sliding seat vertically floatingly connected to the third connecting seat; the second guide rod mechanism and the second clamping mechanism are connected to the third connecting seat, and the tightening mechanism is connected to the sliding seat.
[0025] As can be seen from the above, the vertical floating design of the sliding seat enables the inner support member and the outer clamping member to have a buffering ability when they move downward and dock. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The rewinding and shaping machine of this embodiment is used for performing the rewinding and shaping process of coreless paper rolls.
[0044] See also Figure 1The rewinding and shaping machine of this embodiment includes a guide wheel group 1, a first clamping mechanism 2, a reel mechanism 3, a first guide rod mechanism 4, a driving mechanism 5, a pressing mechanism 6, a tape cutting mechanism 7 and a manipulator 8, combined with Fig.11 The manipulator 8 is integrated with a second guide rod mechanism 80, a tightening mechanism 82 and a second clamping mechanism 83. The rewinding and shaping machine includes a rewinding device and a shaping device. The rewinding device and the shaping device share a reel mechanism 3, that is, the reel mechanism 3 serves as a rewinding reel mechanism of the rewinding device and also as an axis positioning mechanism of the shaping device. The rewinding device also includes the above-mentioned guide wheel set 1, the tape cutting mechanism 7 and the tightening mechanism 82, and the shaping device also includes the above-mentioned first guide rod mechanism 4, the driving mechanism 5, the pressing mechanism 6, the second guide rod mechanism 80 and the second clamping mechanism 83.
[0045] Among them, the guide wheel group 1, the first clamping mechanism 2, the reel mechanism 3, the first guide rod mechanism 4, the driving mechanism 5, the pressing mechanism 6 and the tape cutting mechanism 7 are all arranged on a horizontally arranged workbench, and the robot 8 can be controlled to move horizontally or vertically, and the rewinding and shaping of the paper roll 9 are carried out in the horizontal first plane.
[0046] The guide wheel group 1 includes a plurality of guide wheels 11 and a tensioning wheel 12 arranged in a first plane. The tensioning wheel 12 is arranged between the last two guide wheels 11. The tensioning wheel 12 is connected to the end of the piston rod of the tensioning cylinder 121. The extension of the piston rod of the tensioning cylinder 121 can drive the tensioning wheel 12 forward and tension the paper belt.
[0047] The first clamping mechanism 2 includes a horizontal linear module 21, a vertical linear module 22, a first pneumatic finger 23 and two first clamping members connected in sequence. The two first clamping members serve as the first clamping portion 24 of the present invention. Driven by the horizontal linear module 21 and the vertical linear module 22, the first clamping portion 24 can translate linearly within the first plane, and can also leave the first plane vertically. Driven by the first pneumatic finger 23, the first clamping portion 24 can clamp or release the paper tape.
[0048] Combination Figure 3 The reel mechanism 3 of this embodiment is a reel mechanism for rewinding a coreless paper roll. The reel mechanism 3 includes a first vertical cylinder 38, a first motor 39, a first vertical slide rail member 33, a first mounting frame 32 and a winding shaft 31. The cylinder body of the first vertical cylinder 38 is fixedly connected to the first mounting frame 32. The first motor 39 is connected to the end of the piston rod of the first vertical cylinder 38 and is vertically slidably connected to the first mounting frame 32 through the first vertical slide rail member 33. The winding shaft 31 is connected to the output shaft of the first motor 39 and rotates coaxially. The winding shaft 31 is arranged in the barrel 321 of the first mounting frame 32.
[0049] Driven by the first motor 39 , the winding shaft 31 can rotate around the first axis 300 , and driven by the first vertical cylinder 38 , the winding shaft 31 can be extended and retracted along its own axis between the inside and outside of the barrel 321 .
[0050] Furthermore, the winding shaft 31 includes two half shafts 311 which are arranged at intervals on both sides of the first axis 300. When the winding shaft 31 is extended and retracted in the axial direction, the two half shafts 311 can move in the axial direction and leave the first tape roll position 909. A tape running interval 310 connected in the horizontal direction is formed between the two half shafts 311. The axial direction of the winding shaft 31 is vertical, and when the winding shaft 31 is extended out of the barrel 321, the two half shafts 311 are in the first plane and in the first tape roll position 909. When the winding shaft 31 is retracted into the barrel 321, the two half shafts 311 leave the first plane and leave the first tape roll position 909.
[0051] Furthermore, the first mounting frame 32 also includes a turntable 322 rotatably mounted on the upper end of the cylinder 321 through a bearing, the upper surface of the turntable 322 is the bearing surface of the paper roll 9, the first plane is located above the bearing surface, and the bearing surface of the turntable 322 is provided with two half-axle grooves penetrating vertically, and the two half-axles 311 are respectively slidably mounted in the two half-axle grooves vertically, and the two half-axles 311 can extend above the bearing surface.
[0052] Combination Figure 4 As shown in the schematic diagram of state a, after the rewinding and shaping of the previous paper roll 9 is completed, the end of the paper tape will be clamped by the first clamping portion 24 at the fourth position 904. As shown in the schematic diagram of state a, when the rewinding starts, the winding shaft 31 at the sinking position is located outside the first plane, which will not hinder the translation of the first clamping portion 24 in the first plane. Combined with the schematic diagram of state b, at this time, the first clamping portion 24 can start from the fourth position 904, pass through the first tape roll position 909 and reach the seventh position 907.
[0053] By controlling the first motor 39, the straight-line tape-feeding interval 310 can always maintain an angle matching the straight line through which the paper tape passes at the beginning of each rewinding. At this time, the two semi-axles 311 can be controlled to rise to allow the paper tape to enter the tape-feeding interval 310. As shown in the schematic diagram of state c, the first motor 39 then drives the two semi-axles 311 to rotate to wind the paper tape into a paper roll 9. During the process, the first clamping portion 24 can be controlled at an appropriate time to loosen the clamping of the paper tape.
[0054] After the paper roll 9 is rewound, it is first shaped and then cut. The shaping includes a primary shaping and a secondary shaping which are performed successively. The primary shaping is performed by the first guide rod mechanism 4 and the pressing mechanism 6.
[0055] See also Figure 5The first guide rod mechanism 4 includes a first rod group 42, and the first rod group 42 includes five first guide rods 421 arranged in the same horizontal plane and along a first track, and the first track is roughly "L" shaped. Among them, all the first guide rods 421 are arranged to float vertically, and two of the first guide rods 421 can also be rotated around their own axes. Further, the first guide rod mechanism 4 also includes a first connecting seat 41, and the first guide rod mechanism 4 also includes a second vertical slide rail component 431 and a first vertical spring 432 arranged between the first guide rod 421 that only floats and the first connecting seat 41.
[0056] The first guide rod mechanism 4 also includes a rotating drum 441, a bearing 442 and a second vertical spring 443, that is, the floating and rotatable first guide rod 421 is installed in the middle hole of the rotating drum 441 together with the second vertical spring 443, and the extended two ends of the second vertical spring 443 are respectively abutted between the first guide rod 421 and the rotating drum 441, so that the first guide rod 421 can float vertically relative to the rotating drum 441; and the rotating drum 441 is connected to the first connecting seat 41 through the bearing 442, so that the rotating drum and the first guide rod 421 therein can rotate.
[0057] In fact, it is better that all the first guide rods 421 can float and rotate. However, since the first rod group 42 is used for shaping, the first consideration is that the multiple first guide rods 421 conform to the first trajectory, so that the multiple first guide rods 421 are arranged more closely, and the components required for the first guide rods 421 that both float and rotate occupy a larger space. Therefore, under the premise of satisfying the first trajectory setting, this embodiment selects to set two of the first guide rods 421 to be both floating and rotating, and the remaining three first guide rods 421 can only float but not rotate.
[0058] See also Figure 5 The first guide rod mechanism 4 further includes a second vertical cylinder 48 and a second connection seat 49, the second connection seat 49 is fixedly connected to the cylinder body of the second vertical cylinder 48, and the first connection seat 41 is fixedly connected to the end of the piston rod of the second vertical cylinder 48. In this way, driven by the second vertical cylinder 48, the first rod group 42 can move vertically to enter or leave the first plane.
[0059] Combination Figures 5 to 7 The first guide rod mechanism 4 is horizontally moved by a driving mechanism 5. The driving mechanism 5 includes a rotation driving unit 51, a track assembly, a dual-axis module 54, a moving member 55 and a mounting platform 59; the track assembly includes a track member 53 and a swing member 52.
[0060] The rotation driving unit 51 is a motor. The motor body of the rotation driving unit 51 is located below the mounting platform 59, and its output shaft passes through the mounting platform 59 upward and extends to the top of the mounting platform 59. The output shaft of the rotation driving unit 51 extends vertically and is located at the third axis 500. One end of the swinging member 52 is connected to the output shaft of the rotation driving unit 51. When driven by the rotation driving unit 51, the swinging member 52 can swing around the third axis 500.
[0061] The track member 53 is a plate member and is overlapped and mounted on the upper surface of the mounting platform 59 and is located below the swing member 52. The track member 53 is provided with a track groove 530 which is open upward. The plane where the track groove 530 is located is parallel to the first plane, that is, the plane where the track groove 530 is located is a horizontal plane; the track groove 530 is located on the outer periphery of the third axis 500, and the track groove 530 extends along a non-circular curved track 5309.
[0062] A linear hole 520 is provided on the swing member 52, which penetrates axially and is connected to the track groove 530. In the present embodiment, the linear hole 520 is a straight hole whose extension direction is consistent with the extension direction of the swing member 52. The linear hole 520 penetrates the swing member 52 vertically, and when the swing member 52 rotates around the third axis 500, the linear hole 520 and the track groove 530 remain vertically connected.
[0063] Furthermore, the driving mechanism 5 also includes two detection devices 538 for respectively detecting the forward rotation limit position and the reverse rotation limit position, and the extended end of the swing member 52 is provided with a detection protrusion 528. When the swing member 52 swings to the two limit positions respectively, the detection protrusion 528 can enter the detection range of the two detection devices 538 respectively.
[0064] Furthermore, the driving mechanism 5 also includes a limit block 539 for limiting rotation in two directions. The limit block 539 is a rubber block. When the swing member 52 swings to two extreme positions respectively, the corresponding limit blocks 539 can block the swing member 52 from the front in the rotation direction.
[0065] The dual-axis module 54 includes a first slide rail component 541 and a second slide rail component 542. The first slide rail component 541 includes a first slide rail and a first slider connected in a sliding manner, and the second slide rail component 542 includes a second slide rail and a second slider connected in a sliding manner. The first slide rail of the first slide rail component 541 is fixed on the mounting platform 59 along the first horizontal direction, the second slider of the second slide rail component 542 is cross-connected with the first slider of the first slide rail component 541, and the second slide rail of the second slide rail component 542 extends along a second horizontal direction perpendicular to the first horizontal direction. The second slide rail of the second slide rail component 542 serves as the movable end 543 of the present invention, which can be translated along the first horizontal direction or the second horizontal direction.
[0066] The moving member 55 is a pulley with a rotating axis extending vertically. The moving member 55 is connected to the lower side of the first extension end of the movable end 543 and is placed in the linear hole 520 and located in the track groove 530. The second extension end of the movable end 543 is fixedly connected to the second connecting seat 49. Under this setting, when the rotation driving unit 51 is started, the swinging member 52 swings to force the moving member 55 to translate along the curved track 5309 in the track groove 530, and the first guide rod mechanism 4 will also be driven to translate along the curved track 5309 synchronously.
[0067] See also Figure 8 The pressing mechanism 6 comprises a pressing cylinder 61 and a profiling member 62, wherein the pressing cylinder 61 is arranged horizontally, and the profiling member 62 is connected to the end of the piston rod of the pressing cylinder 61; the profiling member 62 comprises a base surface 621 facing away from the pressing cylinder 61, and the profiling member 62 comprises a convex portion 622 protruding relative to the base surface 621 facing away from the pressing cylinder 61, and a concave position 6220 recessed toward the pressing cylinder 61 is arranged at the protruding end of the convex portion 622, and the concave position 6220 has an inner contour of a circular arc, and the concave position 6220 is vertically penetrated, and the convex portion 622 forms a supporting protrusion 6221 on both sides of the concave position 6220. In addition, a avoidance opening 623 recessed in the base surface 621 facing the pressing cylinder 61 is also arranged at another position in the length direction of the profiling member 62. In addition, a convex edge 624 protruding relative to the base surface 621 facing away from the pressing cylinder 61 is also arranged at the end in the length direction of the profiling member 62. Along the length direction of the profiling member 62 , the convex portion 622 , the avoidance opening 623 and the convex edge 624 are arranged in sequence, and the convex edge 624 is located at the extended end of the profiling member 62 .
[0068] See also Fig. 9 Combined with Figures 5 to 8 As shown in the schematic diagram of state d, when a shaping starts, the first rod group 42 is located in the first plane and at the first position 901, the first position 901 is located between the last guide wheel 11 and the first tape roll position 909, and the first position 901 is located on the inner side of the paper tape.
[0069] As shown in the e state diagram, combined with Fig.10 The driving mechanism 5 drives the first rod group 42 to translate along the curved trajectory 5309 and move from the first position 901 to the second position 902. During the process, the paper tape 91 is guided and deformed, but at this time, the paper tape 91 is not in contact with all the first guide rods 421 on the first rod group 42.
[0070] As shown in the schematic diagram of state f, the pressing mechanism 6 then works, and the profiling member 62 moves in the first plane to the third position 903 opposite to the second position 902. At this time, a shaping position is formed between the first rod group 42 located at the second position 902 and the profiling member 62 located at the third position 903, wherein, under the pressure of the convex portion 622 and the convex edge 624, all the first guide rods 421 of the first rod group 42 are tightly attached to the paper tape, and the paper tape is squeezed in the shaping position to complete a shaping.
[0071] Since the paper tape is stretched at this time, the stretched paper tape is supported on the two supporting protrusions 6221 of the convex part 622, and the concave part 6220 is opposite to the outer side of the paper tape, and the concave part 6220 serves as the second guide rod 811 ( Fig.17 shown).
[0072] See also Figures 11 to 16 The robot 8 integrates a second guide rod mechanism 80 , a tightening mechanism 82 and a second clamping mechanism 83 .
[0073] The manipulator 8 includes a third connection seat 891, a third vertical slide rail member 892, a sliding seat 893 and a third vertical spring 894. The third connection seat 891 is connected to the driving device of the manipulator 8. The sliding seat 893 is vertically slidably connected to the third connection seat 891 through the third vertical slide rail member 892. The third vertical spring 894 is a tension spring and is pulled between the third connection seat 891 and the sliding seat 893. The third connection seat 891 is provided with a vertical limiting groove 8911, and the sliding seat 893 is provided with a limiting column 8931, which is inserted into the limiting groove 8911. In this way, the sliding seat 893 is vertically connected to the third connection seat 891 in a floating manner and the vertical floating amplitude of the sliding seat 893 is limited.
[0074] See also Figures 11 to 14 The tightening mechanism 82 is connected to the sliding seat 893. The tightening mechanism 82 includes a linear drive unit 829, a second motor 828, a reduction wheel assembly 827, a rotating sleeve 825, an outer clamp 822, an inner support member 821 and a forcing member 84.
[0075] The linear drive unit 829 is a vertically arranged cylinder, and the linear drive unit 829 and the second motor 828 are both fixedly connected to the sliding seat 893; the rotating sleeve 825 is vertically arranged and can be rotatably connected to the sliding seat 893 around the second axis 800, and the output shaft of the second motor 828, the reduction wheel assembly 827 and the rotating sleeve 825 are sequentially connected in transmission; the forcing member 84 is inserted in the rotating sleeve 825 and can slide vertically, and the forcing member 84 is connected to the end of the piston rod of the linear drive unit 829; the outer clamp 822 and the inner support member 821 are both slidably installed in the rotating sleeve 825 along the radial direction of the second axis 800.
[0076] Furthermore, combined with Fig.15 The forcing member 84 is in the shape of a trident, and includes a central shaft 841 and a branch structure 842. The top end of the central shaft 841 is connected to the linear drive unit 829, and the bottom end of the central shaft 841 is set to a cone 8411; the two branch structures 842 extend out along the radial direction of the second axis 800 away from the second axis 800 and then bend, and continue to extend along the axial direction of the second axis 800 toward the direction close to the cone 8411 to its end, and the extended end of the branch structure 842 is connected to a roller 843, and the rotation axis of the roller 843 is perpendicular to the axial and radial directions of the above-mentioned second axis 800, and the two rollers 843 and the cone 8411 are located in the same plane.
[0077] Furthermore, the rotating sleeve 825 includes a sleeve portion 8251, a transverse portion 8252 and a turntable portion 8253 which are sequentially arranged from top to bottom. The sleeve portion 8251 is rotatably connected to the sliding seat 893 through a bearing and is fitted with the driven wheel of the reduction wheel assembly 827. The spindle 841 is vertically slidably arranged in the middle hole of the sleeve portion 8251; the transverse portion 8252 is provided with a transverse hole 8250 which penetrates radially along the second axis 800 and is axially connected to the middle hole of the rotating sleeve 825. The lower part of the spindle 841 is located in the transverse hole 8250, and two bifurcated structures 842 extend from the transverse hole 8250 to the outside of the rotating sleeve 825.
[0078] The two inner support members 821 and the two outer clamping members 822 are both slidably installed in the turntable portion 8253 along the radial direction of the second axis 800. A pair of inner support members 821 are respectively arranged on both sides of the second axis 800 at intervals, and a pair of outer clamping members 822 are respectively arranged on both sides of the second axis 800 at intervals. The inner support members 821 are located on the outer periphery of the outer clamping members 822, and radial compression springs (not shown in the figure) are abutted between the inner support members 821 and the outer clamping members 822 located on the same side of the second axis 800. Under the restoring force of the compression springs, the inner support members 821 are maintained at the first inner limit position and the outer clamping members 822 are maintained at the second outer limit position.
[0079] The upper part of the inner support member 821 is provided with a first wedge surface structure 8211 facing the second axis 800, and the upper part of the outer clamping member 822 is provided with a second wedge surface structure 8221 facing away from the second axis 800. The cone portion 8411 and the roller 843 can be inserted into the turntable portion 8253 along the axial direction and reach the position of the inner support member 821 and the position of the outer clamping member 822 respectively. When the linear drive unit 829 drives the forcing member 84 to move downward, the cone portion 8411 abuts against the first wedge surface structure 8211 to force the inner support member 821 to translate radially along the second axis 800 from the first inner limit position to the first outer limit position. At the same time, the roller 843 abuts against the second wedge surface structure 8221 to force the outer clamping member 822 to translate radially along the second axis 800 from the second outer limit position to the second inner limit position.
[0080] A second tape roll position 908 is formed between the lower portion of the inner support member 821 and the lower portion of the outer clamp member 822. The linear drive unit 829 drives the forcing member 84 to move downward, thereby increasing the distance between the inner support member 821 and the second axis 800 and reducing the distance between the outer clamp member 822 and the second axis 800, thereby reducing the size of the second tape roll position 908, so that the paper roll 9 located at the second tape roll position 908 can be clamped by the lower portion of the inner support member 821 and the lower portion of the outer clamp member 822.
[0081] See also Fig.16 The second guiding rod mechanism 80 includes a third vertical cylinder 819 and a second rod group 81 arranged along a second trajectory. Between the second rod group 81 and the first rod group 42, the extension directions of the first guiding rod 421 and the second guiding rod 811 are opposite. Specifically, the first guiding rod 421 extends upward and the second guiding rod 811 extends downward. The cylinder body of the third vertical cylinder 819 is fixedly connected to the third connecting seat 891, and the base plate of the second rod group 81 is connected to the end of the piston rod of the third vertical cylinder 819. Driven by the third vertical cylinder 819, the second rod group 81 can translate vertically.
[0082] See also Fig.16 The second clamping mechanism 83 includes a second pneumatic finger 839 and two clamping members connected to the second pneumatic finger 839. The two clamping members serve as the second clamping portion 831 of the present invention. Driven by the second pneumatic finger 839, the second clamping portion 831 can clamp or release the paper tape.
[0083] Also, see Fig.12 The second tape roll position 908, the second rod group 81 and the second clamping portion 831 are sequentially arranged along the tape path from the paper roll to the paper tape.
[0084] See also Fig. 9 , Fig.10 , Fig.16 and Fig.17As shown in state f, after completing one shaping, the robot arm 8 is controlled to translate and make the second axis 800 coincide with the first axis 300, and then the robot arm 8 is controlled to move vertically downward until the first tape roll position 909 coincides with the second tape roll position 908.
[0085] Before the first belt roll position 909 coincides with the second belt roll position 908, the half-shaft 311 cooperates with the downward movement of the inner support member 821 and the outer clamp member 822 and is controlled to retract downward into the cylinder 321 to avoid interference; wherein, the vertical floating design of the sliding seat 893 enables the inner support member 821 and the outer clamp member 822 to have a buffering ability when moving downward and docking.
[0086] like Fig.17 As shown in state g, after the first tape roll position 909 overlaps with the second tape roll position 908, the two inner supporting members 821 are controlled to move away from each other and the two outer clamping members 822 are controlled to move closer to each other to clamp the paper roll 9.
[0087] See also Fig.16 as well as Fig.17 In the state g shown, while the first tape roll position 909 and the second tape roll position 908 overlap, the first rod group 42 and the second rod group 81 are docked at the second position 902 , and the second clamping portion 831 reaches the sixth position 906 .
[0088] During the tape docking process between the first rod group 42 and the second rod group 81 at the second position 902, the second rod group 81 driven to move downward in the axial direction forces the first rod group 42 to float and leave the first plane. After the paper tape is joined, the second guide rods 811 of the second rod group 81 are located inside the paper tape, and one of the second guide rods 811 is inserted into the recess 6220 and is located outside the paper tape. Then, the second motor 828 controls the tightening mechanism 82 to reverse in the direction opposite to the rewinding direction to tighten the paper tape, thereby completing the secondary shaping.
[0089] Continue to see Fig.17 The g state shown in the figure is followed by the tape cutting action. The second clamping portion 831 located at the sixth position 906 is located at the avoidance opening 623. The setting of the avoidance opening 623 makes the loosening action of the second clamping portion 831 unimpeded. Before the cutting knife is operated, the first clamping portion 24 returns to the fourth position 904, the second clamping portion 831 is located at the sixth position 906, and the tape cutting mechanism 7 moves to the fifth position 905 in the first plane to cut the paper tape. The fifth position 905 is located between the fourth position 904 and the first tape roll position 909.
[0090] The free end of the cut paper tape is clamped by the second clamping portion 831, and the paper roll 9 is clamped by the tightening mechanism 82. The paper tape maintains a trajectory that completely matches the position in the tape box under the support of the second rod group 81. After the robot 8 moves to the box loading station and aligns with the half box of the tape box from above, it moves down to easily and accurately load the paper roll 9 and the paper tape into the box.
[0091] The present invention provides a rewinding and shaping machine for coreless paper rolls. The present invention combines rewinding and shaping into the same workstation to avoid the transfer action and avoid the loosening of paper rolls during the transfer process. The present invention also designs a first clamping mechanism and a winding shaft with two half shafts to complete the rewinding of the coreless paper roll, and the first clamping mechanism is also used for the final tape cutting and fixing, while taking into account the dual functions of rewinding tape feeding and tape cutting clamping. The present invention also designs an inner support and outer clamping tightening mechanism to cope with the rewinding and shaping of coreless paper rolls, avoiding the looseness of paper rolls and affecting the shaping effect or tape cutting. Finally, the present invention also integrates the tightening mechanism, the second guide rod mechanism and the second clamping mechanism on the same mechanical arm to reduce the obstacles to the translation of the first clamping mechanism, with high automation integration, and reduces the investment in the rotation drive unit to reduce costs and reduce the difficulty of control.
[0092] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
