Description

Technical Field

[0001] The present invention relates to the technical field of packaging bag processing equipment, and particularly to a finished packaging bag bag-making and sorting device and its usage method. Background Technique

[0002] A packaging bag refers to a bag used for packaging various items, which facilitates the transportation and storage of goods during the production and circulation process. It is widely used in daily life and industrial production. After the packaging bags are processed, a sorting operation needs to be carried out on the packaging bags. The finished packaging bag bag-making and sorting equipment is one of the most commonly used equipment for sorting packaging bags. It can mainly perform sorting operations on packaging bags to facilitate subsequent transportation operations on the packaging bags.

[0003] For example, in the patent with the publication number: CN217911628U, a sorting device for a plastic woven bag production line is disclosed. It avoids the inclination of the woven bags caused by the simultaneous backward and rightward acting forces during collection, ensures that the woven bags can stably fall into the collection box, improves the stability of the device during use, and at the same time facilitates adjusting the position of the infrared scanning head according to the actual size of the woven bags, reduces the limitations of the device during use, and replaces manual adjustment, saving time and effort and improving the automation ability of the device; it includes a base, a conveying device, a control device, a collection box, a connecting block, a first motor, a rotating block, and multiple groups of rubber plates. The conveying device is fixed on the left side of the top of the base. It is characterized in that it further includes an adapter plate, an infrared scanning head, a power mechanism, two groups of screw sleeves, a fixing plate, two groups of screw rods, and a connecting plate. The adapter plate is fixed on the right side of the top of the conveying device, and the top of the adapter plate is flush with the top of the collection box.

[0004] Although the above-mentioned patented equipment can perform sorting operations on finished packaging bags, it is not convenient to synchronously detect the sizes of the packaging bags, and thus it is not convenient to classify and sort the sorted packaging bags, reducing the adaptability and efficiency of the equipment for sorting packaging bags. Therefore, a finished packaging bag bag-making and sorting device and its usage method are needed to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide a finished packaging bag bag-making and sorting device and its usage method to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: A finished product packaging bag making and sorting device, including a support base seat. At the front and rear of the inner end face of the support base seat, conveying guide rollers are rotationally and detachably connected. The front and rear groups of the conveying guide rollers are meshed and connected by a synchronous conveyor belt. The upper end face of the synchronous conveyor belt is equidistantly provided with packaging bag grooves. At the position of the front conveying guide roller on the side end face of the support base seat, a servo motor is provided. Near the middle of the upper end face of the support base seat, a limit base seat is provided. And at the side end face of the limit base seat, a support guide plate is provided. At the center of the upper end face of the limit base seat, a pen-shaped cylinder is provided. Near the side part of the upper end face of the support guide plate, a rodless cylinder is provided. And at the inner end face of the rodless cylinder, a cylinder slide seat is slidably arranged. At the lower end face of the support guide plate, two linear guide rails are provided. At the lower end faces of the two linear guide rails, linear sliders are slidably arranged.

[0007] A detection device, which is fixedly arranged at the output end of the pen-shaped cylinder, and the detection device is used to detect the size of the packaging bag inside the packaging bag groove;

[0008] A sorting device, which is fixedly arranged at the rear of the cylinder slide seat. The cylinder slide seat is fixedly connected with the linear slider. The sorting device is used for discharging and sorting the packaging bags.

[0009] Preferably, the sorting device includes an L-shaped slide seat. At the middle of the upper end face of the L-shaped slide seat, a mini cylinder is provided. And at the output end of the mini cylinder, a cylinder guide seat is provided. At the center of the lower end face of the cylinder guide seat, a swing cylinder is provided. And at the bottom of the swing cylinder, a fixed base seat is provided. At both sides of the inner end face of the fixed base seat, air guide pipes are fixedly and detachably connected. And at the bottom of the air guide pipe, a vacuum suction cup is fixedly arranged.

[0010] Preferably, the detection device includes a positioning slide seat. At the inner end face of the positioning slide seat, two driven bevel gears are rotationally and detachably connected. And at the rear of the positioning slide seat, a stepping motor is provided. At the output end of the stepping motor, a driving bevel gear is provided. At the inner end faces of the two driven bevel gears, second bidirectional lead screws are fixedly and detachably connected. The inner end face of the positioning slide seat is threadedly connected with a threaded guide seat through the second bidirectional lead screw. And at the center of the lower end face of the threaded guide seat, a positioning base seat is fixedly arranged. At the side end face of the positioning base seat, a guiding motor is provided.

The inner end face of the positioning base seat is threadedly connected with two ball sliders through the first bidirectional lead screw. At the center of the lower end face of the ball slider, a detection module is provided.

[0011] Preferably, both the vacuum suction cup and the alignment slide are aligned with the packaging bag slot, which can effectively improve the accuracy of the subsequent adsorption and sorting of the packaging bags inside the packaging bag slot by the vacuum suction cup. At the same time, the alignment of the alignment slide with the packaging bag slot also facilitates the subsequent rapid and convenient detection operation of the size of the packaging bag slot.

[0012] Preferably, the length and width of the vacuum suction cup are equal to the length and width of the packaging bag slot. The mini cylinder drives the vacuum suction cup to move up and down through the cylinder guide seat, which is convenient for the mini cylinder to drive the cylinder guide seat to move down during subsequent sorting, so as to provide sufficient guiding basis for the vacuum suction cup to adsorb the packaging bags inside the packaging bag slot.

[0013] Preferably, the rodless cylinder drives the sorting device to perform lateral displacement on the upper part of the support clamp through the cylinder slide. When the detection module detects an unqualified packaging bag, the rodless cylinder can drive the sorting device to move laterally to the unqualified packaging bag recycling place through the cylinder slide, so that the standard sorted and discharged packaging bags and the unqualified sorted and discharged packaging bags are misaligned, improving the accuracy of sorting and discharging.

[0014] Preferably, the driving bevel gear is meshed with the two driven bevel gears, and the pen-shaped cylinder drives the alignment slide to move up and down at the bottom of the limit clamp, which is convenient for the subsequent rapid and accurate detection operation of the packaging bags fed into the packaging bag slot.

The servo motor can drive the synchronous conveyor belt and the packaging bag slot to rotate intermittently on the upper part of the support clamp through the two conveying guide rollers, so that the synchronous conveyor belt can position the packaging bags to be detected and sorted to the bottom of the detection device and the sorting device through the packaging bag slot respectively.

[0018] S3: Detecting the packaging bags. The pen-shaped cylinder can drive the alignment slide to move down, and then the alignment slide can drive the threaded guide seat and the four detection modules to move down. The four detection modules can perform positioning detection on the lengths and widths of each side of the packaging bag. If it is necessary to detect packaging bags of different sizes;

[0019] S4: Sort and unload the packaging bags. The mini cylinder can drive the cylinder guide seat and two groups of vacuum suction cups to move downward. At this time, the vacuum suction cups can adsorb the packaging bags. At the same time, the cylinder guide seat can drive the fixed clamping seat to rotate by a certain degree, so that the vacuum suction cups adsorbing the packaging bags rotate to the qualified packaging bag unloading position, and the rodless cylinder for unqualified ones drives the vacuum suction cup to move to the unqualified sorting and unloading position through the cylinder slide seat.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. By setting the sorting device and the rodless cylinder, when sorting the packaging bags, the swing cylinder can drive two groups of vacuum suction cups to alternately sort and unload the packaging bags inside the packaging bag slot, effectively improving the sorting efficiency of the equipment for the packaging bags. At the same time, when sorting the unqualified packaging bags, the rodless cylinder can drive the vacuum suction cup to move synchronously to the unqualified packaging bag sorting and unloading position, effectively improving the classification and sorting efficiency of the equipment for the packaging bags, and also improving the practical performance of the equipment.

[0022] 2.

A rodless cylinder 10 is arranged near the side of the upper end face of the support guide plate 11, and a cylinder slide seat 9 is slidably arranged on the inner end face of the rodless cylinder 10. Two linear guide rails 8 are arranged on the lower end face of the support guide plate 11, and linear sliders 14 are slidably arranged on the lower end faces of the two linear guide rails 8,

[0036] A detection device 4, the detection device 4 is fixedly arranged at the output end of the pen-shaped cylinder 7, and the detection device 4 is used to detect the size of the packaging bag inside the packaging bag groove 6;

[0037] A sorting device 3, the sorting device 3 is fixedly arranged at the rear of the cylinder slide seat 9, the cylinder slide seat 9 is fixedly connected with the linear slider 14, and the sorting device 3 is used for discharging and sorting the packaging bags.

[0038] The sorting device 3 includes an L-shaped slide seat 37. A mini cylinder 31 is arranged in the middle of the upper end face of the L-shaped slide seat 37, and a cylinder guide seat 36 is arranged at the output end of the mini cylinder 31. A swing cylinder 32 is arranged at the center of the lower end face of the cylinder guide seat 36, and a fixed clamping seat 35 is arranged at the bottom of the swing cylinder 32. Guide air pipes 33 are fixedly clamped on both sides of the inner end face of the fixed clamping seat 35, and vacuum suction cups 34 are fixedly arranged at the bottom of the guide air pipes 33.

[0039] The detection device 4 includes a positioning slide seat 41. Two driven bevel gears 49 are rotatably clamped on the inner end face of the positioning slide seat 41, and a stepping motor 46 is arranged at the rear of the positioning slide seat 41. A driving bevel gear 410 is arranged at the output end of the stepping motor 46. Second bidirectional lead screws 48 are fixedly clamped on the inner end faces of the two driven bevel gears 49. Threaded guide seats 42 are threadedly connected to the inner end face of the positioning slide seat 41 through the second bidirectional lead screws 48, and a positioning clamping seat 43 is fixedly arranged at the center of the lower end face of the threaded guide seat 42. A guiding motor 411 is arranged on the side end face of the positioning clamping seat 43, and a first bidirectional lead screw 45 is arranged at the output end of the guiding motor 411. Two ball slide seats 47 are threadedly connected to the inner end face of the positioning clamping seat 43 through the first bidirectional lead screw 45, and a detection module 44 is arranged at the center of the lower end face of the ball slide seat 47.

[0040] The vacuum suction cup 34 and the alignment slide 41 are both facing the packaging bag groove 6, which can effectively improve the accuracy of the subsequent vacuum suction cup 34 in adsorbing and sorting the packaging bags inside the packaging bag groove 6. At the same time, the alignment slide 41 is facing the packaging bag groove 6, which can also facilitate the subsequent quick and convenient detection of the size of the packaging bag groove 6.

[0041] The length and width of the vacuum suction cup 34 are equal to the length and width of the packaging bag groove 6. The mini cylinder 31 drives the vacuum suction cup 34 to move up and down through the cylinder guide seat 36, so that when sorting is performed later, the mini cylinder 31 can drive the cylinder guide seat 36 to move downward, thereby providing sufficient guiding basis for the vacuum suction cup 34 to absorb the packaging bag inside the packaging bag groove 6.

[0042] The rodless cylinder 10 drives the sorting device 3 to move laterally on the upper part of the supporting base 5 through the cylinder slide 9. When the detection module 44 detects unqualified packaging bags, the rodless cylinder 10 can drive the sorting device 3 to move laterally to the unqualified packaging bag recycling area through the cylinder slide 9, so that the packaging bags for standard sorting and the packaging bags for unqualified sorting are misaligned, thereby improving the accuracy of sorting and unloading.

[0043] The active bevel gear 410 is meshedly connected with the two sets of driven bevel gears 49, and the pen-shaped cylinder 7 drives the alignment slide 41 to move up and down at the bottom of the limit clamp 13, which can facilitate the subsequent rapid and accurate detection operation of the packaging bags loaded into the packaging bag slot 6.

[0044] A method for using a finished product packaging bag making and sorting device comprises the following steps:

[0045] S1: Pre-installation, the vacuum conduit can be connected to the air guide tube 33 to provide enough negative pressure inside the vacuum suction cup 34 for operation, and the packaging bag unloading module can be positioned at the rear of the support base 5 to provide enough packaging bags for loading inside the packaging bag slot 6;

[0046] S2: For the conveying and positioning of packaging bags, the servo motor 12 can drive the synchronous conveyor belt 1 and the packaging bag slot 6 to intermittently rotate on the upper part of the supporting base 5 through two sets of conveying guide rollers 2, so that the synchronous conveyor belt 1 can position the packaging bags to be inspected and sorted to the bottom of the inspection device 4 and the sorting device 3 respectively through the packaging bag slot 6;

[0047] S3: For packaging bag inspection, the pen-shaped cylinder 7 can drive the alignment slide 41 to move downward, and then the alignment slide 41 can drive the thread guide 42 and the four detection modules 44 to move downward. The four detection modules 44 can perform positioning inspection on the length and width of each side of the packaging bag, if it is necessary to inspect packaging bags of different sizes;

[0048] S4: Sort and discharge the packaging bags. The mini cylinder 31 can drive the cylinder guide seat 36 and two groups of vacuum suction cups 34 to move downward. At this time, the vacuum suction cups 34 can adsorb the packaging bags. At the same time, the cylinder guide seat 36 can drive the fixed clamping seat 35 to rotate 180 degrees, so that the vacuum suction cups 34 adsorbing the packaging bags rotate to the qualified packaging bag discharging place, and the unqualified rodless cylinder 10 drives the vacuum suction cup 34 to move to the unqualified sorting and discharging place through the cylinder sliding seat 9.

[0049] Working principle: Before use, the staff can connect the vacuum conduit with the air guide pipe 33 to facilitate subsequent work with sufficient negative pressure inside the vacuum suction cup 34. Then, the staff can position the packaging bag feeding module at the rear of the support clamping seat 5 to facilitate subsequent continuous positioning of the packaging bags to be sorted into the packaging bag slot 6. When sorting and conveying the packaging bags, the staff can start the servo motor 12. At this time, the servo motor 12 can drive the synchronous conveyor belt 1 and the packaging bag slot 6 to rotate intermittently above the support clamping seat 5 through two groups of conveying rollers 2, so that the synchronous conveyor belt 1 can position the packaging bags to be detected and sorted to the bottom of the detection device 4 and the sorting device 3 through the packaging bag slot 6 respectively. When detecting the packaging bags, the pen-shaped cylinder 7 can drive the alignment sliding seat 41 to move downward. Then, the alignment sliding seat 41 can drive the threaded guide seat 42 and four groups of detection modules 44 to move downward. The four groups of detection modules 44 can perform positioning detection on the length and width of each side of the packaging bag. If it is necessary to detect packaging bags of different sizes, the staff can start the stepping motor 46 and the guiding motor 411. The stepping motor 46 can drive two groups of driven bevel gears 49 and the second bidirectional lead screw 48 to rotate through the driving bevel gear 410, so that the second bidirectional lead screw 48 can drive the threaded guide seat 42 to move longitudinally. At the same time, the guiding motor 411 can synchronously drive two groups of ball sliding seats 47 to move horizontally through the first bidirectional lead screw 45, so as to adaptively control the horizontal and vertical displacements of the four groups of detection modules 44. After the detection is completed, if the packaging bags in the packaging bag slot 6 are qualified, when the packaging bags move to the bottom of the sorting device 3, at this time, the mini cylinder 31 can drive the cylinder guide seat 36 and two groups of vacuum suction cups 34 to move downward. At this time, the vacuum suction cups 34 can adsorb the packaging bags. At the same time, the cylinder guide seat 36 can drive the fixed clamping seat 35 to rotate 180 degrees, so that the vacuum suction cups 34 adsorbing the packaging bags rotate to the qualified packaging bag discharging place. Then, the vacuum suction cups 34 release the adsorption of the packaging bags. On the contrary, if they are unqualified, after the vacuum suction cups 34 complete the adsorption and rotation, the rodless cylinder 10 can drive the L-shaped sliding seat 37 and the vacuum suction cup 34 to move laterally through the cylinder sliding seat 9, and then drive the vacuum suction cup 34 to move to the unqualified packaging bag sorting and discharging place to complete the classification and discharging.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
