Description

Technical Field

[0001] The present invention relates to a packaging machine, in particular to a full-automatic packaging machine. Background Art

[0002] Existing packaging machines, especially in the textile industry, are mainly used for home textile products such as blankets, curtains, and four-piece quilts. When folding and packing the fabrics, the folding effect of the product is mainly achieved by the cooperation between the belt groups, or by laying the fabrics flat on the template and then folding the template in different directions to achieve the folding effect of the product.

[0003] Objectively speaking, some home textile products need to be folded with linings (the inner lining of the folded fabric), which is time-consuming and labor-intensive to place manually. At least two people are required to place the fabrics neatly in the folding equipment, which makes it easy to get them messy, especially for large fabrics such as curtains and large blankets. In addition, these fabrics are folded in a relatively simple way using existing packaging machines, usually by folding them in half and then in half again.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] See Figures 1 to 11 The fully automatic packaging machine can automatically fold and roll cloth products, including but not limited to blankets, curtains, four-piece sets, small quilts and other home textile products. It can also automatically place lining when the cloth is folded.

[0038] The machine comprises a frame, on which are mounted, in order, a loading unit 1, a lining unit 2, a folding unit, and a discharge unit 5. The loading unit 1 is mounted above the infeed end of the folding unit, the lining unit 2 is positioned above the folding unit, and the discharge unit 5 is positioned at the discharge end of the folding unit. Typically, if lining is not required during fabric folding, the lining unit 2 can be stopped. Furthermore, if fabric needs to be rolled or folded for discharge, the discharge unit 5 can be stopped or moved as needed.

[0039] The feeding unit 1 uses a clamping mechanism to stretch the fabric to both sides until it is flattened and then transported to the folding unit. After being transported to the right position by the first group of front and rear belt conveyors that make up the folding unit, the feeding part 2A that makes up the lining board unit 2 takes the lining and the unloading part 2B places the lining board between the front and rear belt conveyors. The lining board drag plate that makes up the unloading part is driven by an oblique insertion power mechanism to be inserted and pushed into the next group of front and rear belt conveyors of the folding unit to complete the folding.

[0040] After the fabric is folded, it is transported by the discharging unit through the upper and lower belt groups and sucked between the two groups until the fabric is rolled up.

[0041] The implementation principle of the present invention is as follows:

[0042] The worker places the two corners of the fabric on the clamping mechanism of the loading unit 1, which then activates to stretch the fabric until it is flattened. The clamping mechanism then carries the fabric forward and, at the end of its travel, conveys it to the surface of the front belt conveyor group of the first group of front and rear belt conveyors in the folding unit. The first group of front and rear belt conveyors conveys the fabric surface through the gap between the front and rear belt conveyors. The large liner drag plate of the unloading part of the liner placement unit 2 then inserts and pushes the liner onto the fabric at the corresponding gap position. It then cooperates with the first group of front and rear belt conveyors to fold it into the next group of front and rear belt conveyors, where it is folded again as needed before being discharged from the folding unit. This process perfectly combines lining placement and folding, and the number of folds can be reduced or increased as needed by the folding mechanism of the folding unit.

[0043] After coming out of the folding unit, it is transported by the upper and lower belt groups of the discharging unit and then rolled.

[0044] The present invention has a reasonable layout and is easy to operate. Only one person is needed to place the finished product on the loading unit 1, and the loading unit 1 can neatly spread the cloth on the folding unit. The folding unit folds the cloth horizontally according to different folding modes. After the horizontal folding is completed, the cloth can be rolled vertically or folded again vertically according to needs.

[0045] Continue reading Figure 3 、 Figure 4Further, as an improvement to the present invention, the loading unit 1 is installed above the feeding end of the folding unit, and the loading unit 1 includes a loading beam 11 installed on the side frame of the folding unit, and a synchronous belt 13 powered by a servo motor 12 is provided on the loading beam 11; an upper linear guide slider 14 and a lower linear guide slider 15 constituting a clamping mechanism are fixed on the synchronous belt 13, and the upper linear guide slider 14 is installed above the synchronous belt 13, and the lower linear guide slider 15 is installed below the synchronous belt 13, so that when the synchronous belt 13 rotates, the upper linear guide slider 14 and the lower linear guide slider 15 will move in two opposite directions.

[0046] Pneumatic fingers 16 and 17 are installed on the upper and lower linear guide sliders 14 and 15, respectively. In this example, the manual fingers 16 and 17 are installed on the side of the mobile bracket extending from the upper and lower linear guide sliders 14 and 15. A transmission shaft 18 is installed under the loading beam 11. Left and right gears 19 and 20 are installed at both ends of the transmission shaft 18. A drive gear 21 is installed on the transmission shaft 18. A horizontal movement motor 22 engages with the drive gear 21 through a power gear 23 to provide rotation of the left and right gears 19 and 20. Left and right racks are provided on the frame corresponding to the left and right gears 19 and 20. The left and right gears 19 and 20 are matched to engage with the left and right racks, and a longitudinal linear guide 25 is also provided on the frame in the same direction as the left and right racks. This part of the frame is the side frame above the folding unit.

[0047] When this technical solution is implemented, workers place the two right angles of the cloth in the pneumatic fingers 16 and 17 respectively. The pneumatic fingers 16 and 17 clamp the two corners of the cloth and then stretch them to both sides until the cloth is longitudinally flattened. In this process, the servo motor 12 provides the synchronous belt 13 to rotate, and the synchronous belt 13 drives the upper linear guide slider 14 and the lower linear guide slider 15 to move to both sides, thereby realizing the movement of the two corners of the cloth to both sides, and realizing the approach and distance between the finger cylinder 16 and the finger cylinder 17, that is, implementing the stretching of the cloth.

[0048] During the process, when the cloth is lifted and longitudinally flattened by the pneumatic fingers 16 and 17, the bottom of the cloth is laid on the folding unit due to its own gravity, and the top is perpendicular to the horizontal plane. Then the power gear 23 at the output end of the transmission shaft 18 drives the drive gear 21 to drive the transmission shaft 18 to rotate, and the left and right gears 19 and 20 installed at both ends of the transmission shaft 18 rotate. Due to the limiting effect of the longitudinal linear guide 25, the entire loading unit 1 is moved forward or backward on the left and right racks of the folding unit toward the folding unit. When it reaches the set position, the set position is respectively realized by the sensor 2T arranged on the upper and lower linear guide sliders 14 and 15. The sensor 2T can be a proximity switch. The principle is that when the corners of the cloth are placed in the finger cylinders 16 and 17, the sensor 2T controls the finger cylinders 16 and 17 to clamp. When the loading unit 1 completes loading, a touch switch is finally set on the side frame of the folding unit. The entire longitudinal linear guide rail 25 moves to contact the touch switch. The touch switch controls the finger cylinders 16 and 17 to open, and then all the fabrics fall onto the folding mechanism of the folding unit.

[0049] Continue reading Figure 1 、 Figure 5 Further, as an improvement to the present invention, the folding unit includes at least one transverse folding unit 3; the transverse folding unit 3 includes at least two groups of folding mechanisms, each group of folding mechanisms is arranged up and down, and each group of folding mechanisms includes front and rear belt conveyor groups driven by corresponding motors, the motors are servo motors and can independently control the steering speed of each corresponding conveyor group; a position sensor is provided on the front or rear belt conveyor group of each folding mechanism; except for the topmost folding mechanism corresponding to the lining plate unit 2, a lower insert plate is provided in the middle and upper part of the front and rear belt conveyor groups of the folding mechanism below, and the lower insert plates are equipped with independent power cylinders for supplying driving force.

[0050] In the present invention, the equipment is usually equipped with three groups of folding mechanisms when it leaves the factory, including the top first group of front and rear belt conveyor groups 31, 32, the second group of front and rear belt conveyor groups 33, 34 below the first group, and the third group of front and rear belt conveyor groups 35, 36 at the bottom. A finished product conveyor belt group 37 is also provided below the third group. The first group of rear belt conveyor groups 32, the second group of rear belt conveyor groups 34, and the third group of front belt conveyor groups 35 can independently convey fabrics back and forth, ensuring that they can accommodate fabrics of varying thicknesses.

[0051] During the implementation of this technical solution, when the feeding unit 1 delivers the cloth to the folding mechanism at the feed end of the initial folding unit, that is, the cloth is brought to the first front belt conveyor group 31, the motors of the first front belt conveyor group 31 and the first rear belt conveyor group 32 are driven to convey the cloth clockwise simultaneously. When the cloth passes the position sensor S on each folding mechanism, the motors of the first front belt conveyor group and the first rear belt conveyor group 32 stop driving, the lining plate placing unit 2 sucks the lining plate, and then the oblique insertion power mechanism drives the large lining plate drag plate to insert and push it into the gap between the first front belt conveyor group 31 and the first rear belt conveyor group 32. After that, the first front belt conveyor group 31 conveys the cloth clockwise, and the first rear belt conveyor group 32 rotates counterclockwise, pushing the cloth into the gap, completing the first transverse fold.

[0052] After the first transverse folding is completed, the second group of front belt conveyor groups 33 conveys clockwise, and the second group of rear belt conveyor groups 34 also rotates clockwise. When the cloth passes through the position sensor S on the second group of folding mechanisms, the motor controlling the second group of front and rear belt conveyor groups 33 and 34 controls the second group of front and rear belt conveyor groups 33 and 34 to stop conveying. The lower insert plate L set in the middle and upper part of the second group of front and rear belt conveyor groups 33 and 34 is pushed by the power cylinder to assist the cloth to enter the gap of the second group of folding mechanisms. At the same time, the second group of front belt conveyor groups 33 continues to rotate clockwise under the power provided by the motor, and the second group of rear belt conveyor groups 34 rotates counterclockwise under the power provided by the motor, and the cloth completes the second transverse folding through the gap.

[0053] Usually, the fabric only needs to be folded horizontally twice. If only two folds are needed, the fabric can be directly conveyed in the same direction (usually clockwise, depending on the connection direction of the discharge unit) when entering the third group of front and rear belt conveyor groups 35 and 36, and conveyed out of the horizontal folding unit 3 from the side and into the rear discharge unit 5 for finished product folding or rolling.

[0054] If three horizontal foldings are required, at this time, the third group of front and rear belt conveyor groups 35 and 36 both convey counterclockwise. After the cloth passes through the position sensor S of the third group, the motors of the third group of front and rear belt conveyor groups 35 and 36 stop driving at the same time, and the lower insert plate L of the third group is driven downward by the corresponding power cylinder to push the cloth into the gap between the third group of front and rear belt conveyor groups 35 and 36. At this time, the third group of front belt conveyor group 35 continues to convey counterclockwise, and the third group of rear belt conveyor group 36 conveys clockwise. The cloth is further pushed through the gap by friction and enters the finished product conveying belt group 37. At the same time, the finished product conveying belt group 37 conveys clockwise to catch the finished product until the cloth completely falls on the finished product conveying belt group 37, thereby completing the third horizontal folding.

[0055] Afterwards, the finished product conveying belt group 37 continues to convey the finished product toward the discharge unit connected to the folding unit (usually clockwise), and after entering the discharge unit 5, the finished product is folded or rolled.

[0056] Continue reading Figure 1 、 Figure 5 、 Figure 7 Further, as an improvement to the present invention, the feeding part 2A includes a liner placement unit arranged on a parallel fixed guide rail 38, and the liner placement unit includes a left side plate 39 and a right side plate 40. A left liner support plate 41 is fixed on the left side plate 39, and a right liner support plate 42 is fixed on the right side plate 40. The left and right liner support plates 41 and 42 form a certain angle with the horizontal plane, which facilitates the liner placed between the left and right side plates 39 and 40 to slide down; a forward and reverse screw rod 43 passes through the sides of the left and right side plates 39 and 40, and a positive screw nut 44 and a reverse screw nut 45 are respectively installed on the forward and reverse screw rod 43 near the sides of the left and right side plates 39 and 40, so that the distance between the left and right side plates 39 and 40 changes when the forward and reverse screw rod 43 rotates.

[0057] During implementation of this technical solution, the feeding portion 2A adjusts the separation and merging of the left and right liner support plates 41 and 42 by rotating the forward and reverse screw rods 43, thereby varying the spacing between the left and right side plates 39 and 40, thereby accommodating the placement of liners of varying sizes. The liner placement unit is mounted on parallel fixed rails 38, allowing it to be moved longitudinally to any position on the parallel fixed rails 38 manually or by a servo motor. Furthermore, the number of liner placement units can be increased as needed, such as to form two or more groups, to meet customer liner placement requirements.

[0058] Continue reading Figure 1 、 Figure 5 、 Figure 6 、 Figure 8, further, as an improvement to the present invention, the unloading part 2B includes left and right columns 46, 47 respectively fixed on the side frames of the folding unit, a lining board taking beam 48 installed on the left and right columns 46, 47, and a left linear guide 49 and a right linear guide 50 are respectively installed below the left and right columns 46, 47; a lining board large drag plate 51 is fixed on the left and right linear guide rails 49, 50, an oblique insertion cylinder 52 is fixed on the back of the lining board taking beam 48, and the output end of the oblique insertion cylinder 52 is fixed on the lining board large drag plate Plate 51; A longitudinal guide rail 53 is also provided on the lining plate drag plate 51, and a lining plate taking cylinder 54 is fixed on the longitudinal guide rail 53, and a suction cup bracket is installed on the lining plate taking cylinder 54, and a suction cup bracket is provided on the suction cup. One end of the suction cup is connected to the vacuum generator, and the trigger point of the vacuum generator is placed on the output end of the lining plate taking cylinder 54; A lining auxiliary plate 55 is also provided on the lining plate drag plate 51; The lining auxiliary plate 55 is fixed between the left and right columns 46 and 47 and close to the end of the lining plate large drag plate 51.

[0059] When this technical solution is implemented, the end of the lining cylinder 54 is extended, and the vacuum generator is triggered at the same time. The suction cup on the suction cup bracket starts to work, and the suction cup is pushed out to the lining plate along with the output end at the same time. The suction cup sucks the lining plate of the feeding part 2A, and then retracts and is placed on the lining plate large drag plate 51. The output end triggers the vacuum generator trigger point again to turn off the vacuum generator, and the lining plate is completely dragged by the lining plate large drag plate 51.

[0060] When the folding unit needs to fold for the first time, the obliquely inserted cylinder 52 pushes the lining plate slide 51 downward to assist the folding unit in folding the fabric horizontally. At the same time, as the lining plate slide 51 further descends, the lining plate auxiliary plate 55 is first pushed onto the lining plate auxiliary plate 55. As the lining plate slide 51 further descends, the friction between the two contact points changes, and the lining plate is then smoothly placed into the fabric being folded.

[0061] Continue reading Figure 1 、 Figure 9 Further, as an improvement to the present invention, the folding unit also includes a longitudinal folding unit 4, which includes a scissor-type lifting mechanism 3A and a clamping mechanism 3B installed on the scissor-type lifting mechanism 3A; the scissor-type lifting mechanism includes a base 56 and an upper main frame 57, and the upper main frame 57 is provided with a longitudinal conveying belt group. At least one lifting unit is arranged between the base 56 and the upper main frame 57. During implementation, there are preferably 4 lifting units, which are distributed in four positions below the upper main frame 57; the lifting unit is composed of a lifting cylinder 58, an extension support rod 59 pushed by the forward and backward extension of the output end of the lifting cylinder 58, and a passive support rod 60 hinged to the extension support rod 59 and fixed at least one end to the base 56 or the upper main frame 57.

[0062] Usually lifting cylinder 58 is installed on the base 56, stretches support rod 59 other end and is hinged on the upper main frame 57 like this. If lifting cylinder 58 is installed on the upper main frame 57, stretches support rod 59 other end and is hinged on the base 56.

[0063] One end of the passive support rod 60 is fixed on the base, and a limit groove or limit frame is set under the upper main frame 57. A roller is set at the other end of the passive support rod 60. The roller is limited to rolling in the limit groove or limit frame and slides in the limit groove or limit frame when the output end of the lifting cylinder 58 is extended or retracted, thereby extending the support rod 59 and the passive support rod 60 to open, so that the upper main frame 57 is away from the base 56, and the height of the upper main frame 57 is increased.

[0064] During implementation, both ends of the passive support rod 60 can be hinged to the base 56 and the upper main frame 57 respectively.

[0065] Continue reading Figure 1 、 Figure 9 、 Figure 10 Further, as an improvement to the present invention, the clamping mechanism 2B includes a front support frame 61 and a rear support frame 62, and the front and rear support frames 61 and 62 are respectively mounted on the sides of the upper main frame 57, and the front and rear support frames 61 and 62 are respectively provided with front and rear linear guide rails 63 and 64, and a slide cylinder 65 is installed on the front linear guide rail 63 or the rear linear guide rail 64; a front side plate 66 is installed on the front linear guide rail 63, and a rear side plate 67 is installed on the rear linear guide rail 64, and the front and rear side plates 66 and 67 are fixedly connected to the side of a clamping jaw 68, and the clamping jaw 68 is connected to a clamping jaw 69 by a hinge; the front and rear side plates 66 and 67 are connected by a bridging profile 70, and a bite cylinder 71 is fixed on the bridging profile 70, and the output end of the bite cylinder 71 is fixed to the clamping jaw 69.

[0066] When this technical solution is implemented, the lower jaw 68 and the upper jaw 69 of the clamp are pushed by the slide cylinder 65 to the edge of the last belt conveyor group of the folding mechanism where the folding unit is scheduled to discharge the material, and the cloth is transported between the lower jaw 68 and the upper jaw 69 of the clamp. At this time, the engaging cylinder 71 activates and pushes the upper jaw 69 to merge toward the lower jaw 68 to achieve engaging the cloth. Then the slide cylinder 65 retracts to drag the cloth to the belt surface of the longitudinal conveying belt group on the upper main frame 57.

[0067] Continue reading Figure 1 、 Figure 9 、 Figure 10As a further improvement to the present invention, the upper main frame 57 is provided with a longitudinal folding mechanism. The longitudinal folding mechanism includes a longitudinal conveying belt assembly 72, a belt servo motor 73 that drives the longitudinal conveying belt assembly 72, and a Y-shaped flip paddle 74 disposed at the other end of the longitudinal conveying belt assembly 72. The Y-shaped flip paddle 74 is driven by a flip servo motor 75. Gaps are left between the longitudinal conveying belts that make up the longitudinal conveying belt assembly 72. The Y-shaped flip paddle 74 is disposed below the gaps and is indirectly or directly coupled to the output end of the flip servo motor 75.

[0068] During implementation of this technical solution, the fabric that has been folded laterally is pulled by the clamping mechanism 2B onto the longitudinal conveyor belt assembly. The fabric is then driven by the belt servo motor 73 to move backward. The belt servo motor 73 rotates for a predetermined period of time, and the flip servo motor 75 is activated. The flip servo motor 75 drives the Y-shaped flip paddle 74 to rotate counterclockwise. The Y-shaped flip paddle 74 flips upward through the gap between the longitudinal conveyor belts, thereby completing the folding of one end of the fabric that is passing above. The belt servo motor 73 rotates to cause the fabric to continue moving backward. The flip servo motor 75 again reverses and drives the Y-shaped flip paddle 74 to rotate clockwise, completing the folding of the other end of the fabric.

[0069] In actual implementation, if there are more folding requirements, the above steps can be repeated.

[0070] Continue reading Figure 1 、 Figure 11 , Figure 12 The discharging unit 5 includes a main frame 76, an upper belt group 77 and a lower belt group 78 which are arranged at an angle. The upper belt group 77 is equipped with an upper servo motor 79 to provide conveying power. At least one edge detection sensor 89 is installed on the main frame 76 corresponding to the cloth entrance. The lower belt group 78 is equipped with a lower servo motor 80 to provide conveying power. The upper and lower servo motors 79 and 80 can rotate forward and backward independently. The upper belt group 77 is suspended on the main frame 76 by a front linear guide 81 and a rear linear guide 82, and a transverse servo motor 83 provides transverse movement of the upper belt group 77 through a screw rod 87. The edge detection sensor is connected to the circuit that controls the upper servo motor 79 and the transverse servo motor 83. The lower belt group 78 is installed on the main frame 76 by a left linear guide 84 and a right linear guide 85, and a longitudinal servo motor 86 provides the lower belt group 78 with forward and backward movement through a longitudinal screw rod (not marked in the figure), adjusting the size of the gap between the two belt groups to adapt to different winding diameters. A push-out cylinder 88 is also provided on one side between the upper and lower belt groups.

[0071] When this technical solution is implemented, the discharge unit 5 is usually connected to the front of the longitudinal folding unit 4. The lower belt group 78 of the discharge unit 5 conveys counterclockwise, and the upper belt group 77 conveys clockwise. Friction suction is generated between the upper and lower belt groups 77 and 78 to frictionally suck the fabric between the two belt groups.

[0072] The edge detection sensor 89 is used to sense the entry of cloth, and then the edge detection sensor cooperates with the upper belt group 77 and the lower belt group 78. At a predetermined time (actually, the number of revolutions of the upper and lower servo motors 79 and 80 is the time limit), when the cloth enters the center position between the upper and lower belt groups, the upper servo motor 79 is controlled to rotate in the opposite direction, so that the upper belt group 77 is transported counterclockwise, while the lower belt group 78 continues to transport counterclockwise. The upper and lower surfaces of the cloth are subjected to opposite friction forces, so that the edge of the cloth rubbing against the surface of the upper belt group 77 is rolled up.

[0073] When the upper side edge of the cloth is rolled up, the lower belt group 78 continues to push the lower surface of the cloth forward, and the upper belt group 77 continues to push the upper surface of the cloth backward, so the cloth begins to roll up in the middle position of the upper and lower belt groups 77 and 78.

[0074] The cloth in the middle of the upper and lower belt groups 77 and 78 is rolled into a circle, which compresses the surfaces of the upper and lower belt groups 77 and 78 to concave inward and deform them. Because the belt in the middle of the upper and lower belt groups 77 and 78 has no support, it can be seen that the belt in the middle slowly concave and forms an arc shape from the beginning of rolling.

[0075] As the roll gets bigger, the surface tension of the upper and lower belt groups 77 and 78 in contact with the cloth becomes tighter and reacts to the surface of the rolled cloth, making the roll tighter.

[0076] When the number of winding turns, that is, the number of rotations of the upper or lower servo motor reaches a certain value, the longitudinal servo motor 86 is started, so that the lower belt group 78 is appropriately withdrawn forward, leaving more space at the rear to accommodate winding until the finished product is completely rolled up.

[0077] During the fabric rolling process, when the edge detection sensor 89 detects that the fabric is offset in the lateral direction, the lateral servo motor 83 is controlled to move the upper belt group in the lateral direction, so that the fabric can be rolled more neatly.

[0078] When the finished product is completely rolled up, the sensor at the entry end does not sense any cloth entering, and the upper and lower belt groups 8 continue to roll for a period of time (the time determination principle is the same as described above). The upper and lower servo motors 79 and 80 stop, and then the push-out cylinder 88 pushes the rolled cloth out from the side between the upper and lower belt groups 77 and 78, making it convenient for workers to bag the rolled cloth.
