Description

Technical Field

[0001] The utility model relates to the field of packaging machines, in particular to a full-automatic hanging bag folding, compressing, shaping and packaging and sorting mechanism. Background Art

[0002] In order to facilitate the preservation and transportation of food, food needs to be packaged. When packaging some snacks, adjacent two small packages are usually packaged in a head-to-tail connection manner. The number of small packages connected in series is generally ten or twenty small packages connected head-to-tail. The number of small packages connected in series is mainly determined by the number that can be accommodated in the large package. In order to facilitate sales, multiple small connected packages of snacks need to be folded and compressed and then bagged in a large package. Some food packaging equipment on the market uses the method of hanging bags to carry out folding and gathering. Multiple small connected packages need to use multiple hanging rods to support the joints between every two small packages among the first, second, third, fourth, fifth, sixth, etc. small packages respectively to complete the upward folding of adjacent two small packages. All the hanging rods are moved closer to each other to fold and gather the small packages to the smallest volume. Such packaging equipment has the disadvantages of complex structure, high cost and troublesome maintenance, which is not conducive to the development of the industry. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a full-automatic hanging bag folding, compressing, shaping and packaging and sorting mechanism.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions: The full-automatic hanging bag folding, compressing, shaping and packaging and sorting mechanism includes a first fixed bracket and a second fixed bracket arranged in parallel with it. On both sides of the first fixed bracket and the second fixed bracket, there are respectively a first fixed large plate and a second fixed large plate. One end side of the first fixed large plate is provided with a feeding conveyor line for feeding and conveying food connected packages. Above the first fixed large plate, there is a leveling brush assembly for conveying food connected packages and limiting and preventing arching of food connected packages. One side of the leveling brush assembly is provided with a blowing and folding assembly for blowing air at the joints of food connected packages to fold the joints downward. On the side of the first fixed large plate facing away from the second fixed large plate, there is a hanging bag assembly, which hangs and drives the movement of food connected packages. On one side surface of the first fixed large plate, there is a double-sided synchronous conveyor belt for limiting and conveying folded packages in a slack state during conveying. On the second fixed large plate, there is a tail pushing assembly for pushing and compressing folded packages. On the second fixed large plate, there is a side pushing assembly for laterally pushing folded packages in a compressed state.

[0005] Preferably, the bag hanging assembly includes a lifting large plate. On one side of the lifting large plate facing away from the first fixing bracket and the second fixing bracket, there is a first motor. The output end of the first motor is provided with a speed reducer. The output end of the speed reducer is provided with a driving sprocket. On the same side surface of the lifting large plate, there is a first driven sprocket. The driving sprocket is drivingly connected to the first driven sprocket through a first chain. On the other side of the lifting large plate, there are respectively a second driven sprocket, a third driven sprocket, a fourth driven sprocket and a fifth driven sprocket. The first driven sprocket is fixedly connected to the second driven sprocket through a rotating shaft. The second driven sprocket, the third driven sprocket, the fourth driven sprocket and the fifth driven sprocket are sequentially drivingly connected through a second chain. On the second chain, there is a hanging rod for hanging food connecting bags. The hanging rod is installed on the second chain through a hanging rod bracket. On one side surface of both ends of the lifting large plate facing the first fixing large plate, there are respectively linear bearings. On the first fixing bracket and the second fixing bracket, there are respectively first guide rods. The first guide rods and the linear bearings are adaptively installed. The lifting large plate slides up and down on the first fixing bracket and the second fixing bracket through the linear bearings and the first guide rods. On one side of both ends of the lifting large plate facing the first fixing large plate, there are respectively handwheel screw rod kits. On both ends of the first fixing large plate, there are respectively nut seats. The handwheel screw rod kits and the nut seats are adaptively installed. By rotating the handwheel screw rod kits, the lifting large plate is driven to slide up and down on the first fixing large plate. At one end of the lifting large plate close to the feeding conveyor line, there is a detection photoelectric eye for detecting that the food connecting bags are conveyed in place on the feeding conveyor line. The detection photoelectric eye is fixedly installed on the lifting large plate through a first mounting bracket. The detection photoelectric eye can adopt a detection photoelectric eye with the model KJT-FS3-40NT, but is not limited thereto.

[0006] By adopting the above technical solution, since the forward and reverse rotation of the handwheel screw rod kit can drive the lifting large plate to move up and down along the first guide rod, the hanging rod can move up and down with the lifting of the lifting large plate to adjust the height of the hanging rod relative to the double-sided synchronous conveyor belt. The above design can ensure that the joints of the two frontmost packages of the food continuous package can be hung on the hanging rod, and at the same time, the adjacent downward-folded joints can fall on the double-sided synchronous conveyor belt to be applicable to hanging packages of food continuous packages with different lengths of single packages. The detection photoelectric eye can automatically monitor the food continuous package. When the detection photoelectric eye detects that the food continuous package is conveyed in place, the first motor drives the driving sprocket to rotate. When the driving sprocket rotates, the first driven sprocket can be driven to rotate synchronously through the first chain. Since the first driven sprocket is fixedly connected to the second driven sprocket through a rotating shaft, the second driven sprocket can rotate with the rotation of the first driven sprocket. The rotation of the second driven sprocket and its cooperation with the third driven sprocket, the fourth driven sprocket and the fifth driven sprocket can drive the second chain to rotate. When the second chain rotates, it can drive the hanging rod to reach below the front end of the feeding conveyor line in the conveying direction. The feeding conveyor line automatically conveys the food continuous package. When the two frontmost packages of the food continuous package fall from the feeding conveyor line, the joints of the two frontmost food packages in the food continuous package will be placed on the hanging rod, causing the joints of the two frontmost food packages to fold upward. When the first motor in the hanging package assembly drives the second chain to drive the food continuous package to move forward at a speed slower than the conveying speed of the feeding conveyor line, the conveying speed of the feeding conveyor line for the food continuous package is faster than the speed of the hanging rod driving the food continuous package. The feeding conveyor line conveying the food continuous package can prompt the subsequent food packages to be automatically folded, enabling it to automatically fold the food continuous package.

[0007] Preferably, the leveling brush assembly includes a second motor, a roller brush is provided at the output end of the second motor, and the second motor is fixed on the lifting large plate through a motor mounting plate; the air blowing and folding assembly includes a second guide rod, the second guide rod is fixedly installed on one side surface of the motor mounting plate, a clamping member is provided on the second guide rod, a second mounting bracket is provided on the clamping member, and an air nozzle for blowing air on the joints of the food continuous package is provided on the second mounting bracket.

[0008] By adopting the above technical solution, when the second motor in the leveling brush assembly drives the roller brush to rotate, it can drive and convey the food continuous package and limit the food continuous package to prevent the food continuous package from arching. By externally connecting the air nozzle in the blowing and folding assembly to a gas supply device, when the airflow of the gas supply device blows towards the food continuous package through the air nozzle, it can cause the next joint adjacent to the joint where the food continuous package folds upward to fold downward. Since the folded-down joint is located below the surface position of the feeding conveyor line, and the leveling brush assembly can limit the food continuous package to prevent arching, when the conveying speed of the feeding conveyor line is faster than the speed at which the bag hanging assembly drives the food continuous package to move, it can cause the next joint of the currently downward-folded joint of the food continuous package to automatically fold upward, and the blowing and folding assembly blows air to the next joint adjacent to the currently upward-folded joint to make it automatically fold downward, realizing automatic folding of the food continuous package until it becomes a folded package.

[0009] Preferably, the double-sided synchronous conveyor belt includes a driving synchronous wheel and a driven synchronous wheel installed on one side of the first fixed large plate facing away from the second fixed large plate. A third motor is provided on the other side of the first fixed large plate, and the output shaft of the third motor is connected to the driving synchronous wheel. The driving synchronous wheel is drivingly connected to the driven synchronous wheel through a synchronous belt. The synchronous belt is provided with grooves, and the grooves limit the joints where the food continuous package folds downward.

[0010] By adopting the above technical solution, when the third motor drives the synchronous belt to rotate through the driving synchronous wheel and in cooperation with the driven synchronous wheel, the grooves on the synchronous belt can be driven to rotate when the synchronous belt rotates; when the conveying speed of the double-sided synchronous conveyor belt for the folded package formed by folding is the same as the speed at which the bag hanging assembly drives the food continuous package to move, the joints where the food continuous package folds downward will fall into the grooves of the synchronous belt in the double-sided synchronous conveyor belt. The grooves can limit the joints where the food continuous package folds downward to shape the folded package formed by folding, preventing the folded package from sliding on the synchronous belt and becoming loose and flattened. The synchronous belt plays a role in folding and shaping the food continuous package in a loose folded state. When the double-sided synchronous conveyor belt conveys the folded package to the front end position in its conveying direction, the food continuous package is in a loose folded and shaped state, and subsequent pressing and shaping are required.

[0011] Preferably, the tail pushing assembly includes a fourth motor installed on one side of one end of the second fixed large plate. A linear module is provided on the second fixed large plate, and a first cylinder is provided on the linear module. The first cylinder can slide on the linear module. A synchronous belt and synchronous wheel kit is provided on the other side of the second fixed large plate. The fourth motor drives the first cylinder to slide on the linear module through the synchronous belt and synchronous wheel kit. A connecting plate is provided on the output shaft of the first cylinder, and a first pushing plate is provided on the connecting plate.

[0012] Preferably, a platform for carrying the folded package is provided on one side of the double-sided synchronous conveyor belt, and a side plate is provided at one end of the platform away from the double-sided synchronous conveyor belt.

[0013] By adopting the above technical solution, since the fourth motor can drive the first cylinder to reciprocate linearly on the linear module through the synchronous belt and synchronous pulley kit, when the fourth motor in the tail pushing assembly drives the first cylinder to move to the side away from the side pushing assembly on the linear module through the synchronous belt and synchronous pulley kit, the first push plate extends to the side of the folded package under the drive of the first cylinder. The first motor in the bag hanging assembly drives the second chain to drive the hanging rod to move, thereby driving the folded package to move towards the platform at a speed faster than the conveying speed of the continuous package on the double-sided synchronous conveyor belt. At the same time, the fourth motor drives the first push plate to push the compressed package to compress the folded package at a speed faster than the direction in which the current hanging rod drives the folded package to move towards the side plate. The speed at which the first push plate pushes the folded package in the relaxed state is faster than the speed at which the hanging rod drives the folded package to move, which is beneficial to realizing that the first push plate pushes and compresses the folded package at the same time. With the side plate of the platform as a reference, the first push plate pushes and presses the folded package into a folded and compressed state until the food continuous package is folded and compressed into a folded and compressed body with the smallest volume, realizing the full-automatic compression of the folded package.

[0014] Preferably, the side pushing assembly includes a mounting bottom plate mounted on the first fixed large plate. A cylinder mounting plate is provided on the mounting bottom plate, a second cylinder is provided on the cylinder mounting plate, a second push plate is provided on the output shaft of the second cylinder, and a guide rod bearing assembly is also mounted on the cylinder mounting plate. One end of the guide rod bearing assembly is fixedly connected to the second push plate. The second cylinder pushes the folded package in the compressed state through the second push plate, and the guide rod bearing assembly guides the second push plate.

[0015] By adopting the above technical solution, when the second cylinder in the side pushing assembly pushes the second push plate to extend, it can push the folded and compressed body of the food continuous package away from the platform and be pushed to the next station, thus completing the folding and compression of the food continuous package. After the food continuous package is folded and compressed, it is convenient for subsequent packaging bagging. The bag hanging assembly can realize hanging the food continuous package with only one connecting rod, and it can cooperate with the first push plate of the tail pushing assembly to compress the folded package in the relaxed state, replacing the method of using multiple hanging rods to close and compress the folded package in the existing food packaging equipment on the market. It has the advantages of simple structure, low production cost, simple maintenance, low maintenance cost, and can reduce the food packaging cost.

[0016] Preferably, a controller or control system is provided for signal control with components such as the feeding conveyor line, leveling brush assembly, bag hanging assembly, double-sided synchronous conveyor belt, tail pushing assembly, and side pushing assembly. The controller is a PLC programmable logic controller, and the PLC programmable logic controller can adopt a programmable logic controller with the model XDS-40T-D, but it is not limited thereto.

[0017] It should be noted that both the motor mounting plate and the cylinder mounting plate are functional descriptions of the mounting plate. The mounting base plate is a functional description of the base plate. The handwheel screw rod kit includes a handwheel and a ball screw fixedly connected to the handwheel, and the ball screw is rotatably connected to the nut seat. The guide rod bearing assembly includes a bearing and a guide rod passing through the bearing. The synchronous belt and pulley kit includes two belt pulleys and a belt connecting the two belt pulleys. The linear module includes a slide rail and a slider sliding on the slide rail, and the first cylinder is mounted on the slider. The belt in the synchronous belt and pulley kit is connected and mounted to the first cylinder through a belt fixing clip.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. By providing a hanging bag assembly on the side of the first fixed large plate facing away from the second fixed large plate and designing the structure of the hanging bag assembly, it ensures that the joints of the two frontmost packages of the food continuous bag can be hung on the hanging rod, and at the same time, the adjacent downward-folded joints in the food continuous bag can fall on the double-sided synchronous conveyor belt, making it applicable to hanging bags for food continuous bags with single packages of different lengths; after the joints of the two frontmost food packages in the food continuous bag are placed on the hanging rod, the joints of the two frontmost food packages in the food continuous bag will automatically fold upward; when the first motor in the hanging bag assembly drives the second chain to drive the food continuous bag to move forward at a speed slower than the feeding conveyor line, the feeding conveyor line conveys the food continuous bag at a speed faster than the hanging rod drives the food continuous bag, so that when the feeding conveyor line conveys the food continuous bag, it can prompt the subsequent food packages to automatically fold. It realizes hanging bags for food continuous bags with only one connecting rod and cooperates with the first push plate of the tail pushing assembly to compress the folded bag in a relaxed state. It has the advantages of simple structure, high packaging efficiency, good packaging effect, low production cost, low packaging cost and easy maintenance, and effectively solves the problems of complex structure, high production cost, high maintenance cost and high packaging cost of the existing food packaging equipment that uses multiple hanging rods to converge with each other to compress the folded bag.

[0019] 2. By providing a leveling brush assembly at the output end of the feeding conveyor line and designing the structure of the leveling brush assembly, the leveling brush assembly can limit and prevent the food continuous bag passing through it from arching. When the conveying speed of the feeding conveyor line is faster than the speed at which the hanging bag assembly drives the food continuous bag to move, it can prompt the next joint of the currently downward-folded joint in the food continuous bag to fold upward. At the same time, it also uses the leveling brush assembly in cooperation with the blowing and folding assembly. The blowing and folding assembly can blow air to the next joint adjacent to the currently upward-folded joint in the food continuous bag, enabling it to automatically fold downward, and realizing automatic folding of the food continuous bag until completion.

[0020] 3. It is provided with a double-sided synchronous conveyor belt on one side of the first fixed large plate for limiting and conveying the folded package in a slack state, and the structure of the double-sided synchronous conveyor belt is designed such that the groove of the synchronous belt in the double-sided synchronous conveyor belt can limit the joints folded downward in the food continuous package to shape the folded package after folding, preventing the folded package from sliding on the synchronous belt and becoming loose and flattened. The synchronous belt can play a role in folding and shaping the food continuous package in a slack folded state, ensuring good folding and shaping effect and high folding and shaping efficiency of the food continuous package.

[0021] 4. It is provided with a tail-pushing component for pushing and compressing the folded package on the second fixed large plate and the structure of the tail-pushing component is designed. When the first motor in the bag-hanging component drives the second chain to drive the hanging rod to move, thereby driving the folded package to move towards the platform at a speed faster than the speed at which the double-sided synchronous conveyor belt conveys the food continuous package, the fourth motor in the tail-pushing component drives the first push plate to push and compress the package towards the side plate at a speed faster than the speed at which the current hanging rod drives the folded package and compress the folded package. And the speed at which the first push plate pushes the folded package in a slack state is faster than the speed at which the hanging rod drives the folded package, which is beneficial to realizing that the first push plate can push and compress the folded package at the same time. The folded package is based on the side plate of the platform. When the first push plate pushes and presses the folded package to the folded and compressed state, the food continuous package is folded and compressed into the smallest volume of folded and compressed body, realizing the full-automatic compression of the folded package.

[0022] 5. It is provided with a side-pushing component for laterally pushing the folded package in a compressed state on the second fixed large plate and the structure of the side-pushing component is designed, enabling it to push the folded and compressed body formed by folding and compressing the food continuous package away from the platform and push it into the next working station through the side-pushing component to complete the automatic discharging of the folded and compressed body.

[0042] In one embodiment, a platform 95 for carrying the folded package is provided on one side of the double-sided synchronous conveyor belt 9. A side plate 96 is provided at one end of the platform 95 away from the double-sided synchronous conveyor belt 9.

[0043] In another embodiment, the present utility model further provides a material handling process for a fully automatic bag hanging, folding, compressing, shaping, and packaging material handling mechanism: the connected food bag segments (referred to as food continuous bags) are conveyed and loaded through the feeding conveyor line 5 and conveyed towards the bag hanging assembly 8. The bag hanging assembly 8 can drive the lifting large plate 80 to move up and down along the first guide rod 804 through the rotating handwheel screw rod kit 805 to adjust the height of the hanging rod 801 relative to the double-sided synchronous conveyor belt 9, ensuring that the joints of the two food packages at the front of the food continuous bag can be hung on the hanging rod 801, and at the same time, the joints of adjacent two food packages folded downwards can fall on the double-sided synchronous conveyor belt 9 to be applicable to hanging bags for food continuous bags with single packages of different lengths; the detection photoelectric eye 807 monitors the food continuous bag. When it detects that the food continuous bag is conveyed in place, the first motor 81 drives the second chain 89 to rotate through the driving sprocket, the first chain 84, the first driven sprocket 83, and the second driven sprocket 85. When the second chain 89 rotates, it can drive the hanging rod 801 to reach below the front end of the conveying direction of the feeding conveyor line 5. As the feeding conveyor line 5 continuously conveys the food continuous bag, the two food packages at the front of the food continuous bag will fall from the feeding conveyor line 5, enabling the joints of the two food packages at the front to be placed on the hanging rod 801 and the joints of the two food packages at the front to be folded upwards; when the first motor 81 in the bag hanging assembly 8 drives the second chain 89 to drive the food continuous bag to move forward at a speed slower than the conveying speed of the feeding conveyor line 5, the conveying speed of the feeding conveyor line 5 for the food continuous bag is faster than the speed of the hanging rod 801 driving the food continuous bag. At this time, the conveying of the food continuous bag by the feeding conveyor line 5 prompts the subsequent food packages to be automatically folded.

[0044] When the food continuous bag is conveyed past the leveling brush assembly 6, the second motor 61 in the leveling brush assembly 6 drives the roller brush 62 to rotate to drive and convey the food continuous bag and limit the food continuous bag to prevent it from arching; since the air nozzle 74 in the blowing and folding assembly 7 is externally connected to a gas supply device, the airflow of the gas supply device blows towards the food continuous bag through the air nozzle 74, causing the next joint adjacent to the joint of the food continuous bag folded upwards to be folded downwards; and since the folded-down joint is located below the surface position of the feeding conveyor line 5, when the leveling brush assembly 6 limits the food continuous bag to prevent arching and the conveying speed of the feeding conveyor line 5 is set to be faster than the speed of the bag hanging assembly 8 driving the food continuous bag to move, it can prompt the next joint of the currently folded-down joint to be automatically folded upwards, and when the blowing and folding assembly 7 blows air to the next joint adjacent to the currently folded-up joint, it can make it automatically fold downwards, realizing the automatic folding of the food continuous bag.

[0045] It is provided with grooves 90 on the synchronous belt 94 in the double-sided synchronous conveyor belt 9. When the speed of the double-sided synchronous conveyor belt 9 for conveying the folded and formed folded package is the same as the speed of the bag hanging assembly 8 for driving the food connected bags to move, the downward-folded joints in the food connected bags can fall into the grooves 90 of the synchronous belt 94 in the double-sided synchronous conveyor belt 9. The grooves 90 can limit the downward-folded joints falling into them to shape the folded and formed folded package, preventing the folded package from sliding and spreading out flat on the synchronous belt 94. The synchronous belt 94 with the grooves 90 designed can play a role in folding and shaping the food connected bags in a loose folded state.

[0046] When the food connected bags are conveyed past the tail pushing assembly 10, the fourth motor 101 in the tail pushing assembly 10 drives the first cylinder 103 to move on the linear module 102 to the side away from the side pushing assembly 11 through the synchronous belt and synchronous pulley kit 104. The first cylinder 103 drives the first push plate 106 to extend to the side of the folded package. The first motor 81 in the bag hanging assembly 8 drives the second chain 89 to drive the hanging rod 801 to move, thereby driving the folded package to move in the direction of the platform 95 at a speed faster than the speed of the double-sided synchronous conveyor belt 9 for conveying the food connected bags. At the same time, the fourth motor 101 drives the first push plate 106 to push the compressed package to move in the direction of the side plate 96 at a speed faster than the speed of the current hanging rod 801 driving the folded package and compress the folded package. When the speed of the first push plate 106 pushing the loose folded package is faster than the speed of the hanging rod 801 driving the folded package, it is beneficial to realize that the first push plate 106 pushes the folded package while compressing the folded package. Taking the side plate 96 of the platform 95 as a reference, the first push plate 106 pushes and presses the folded package to the folded and compressed state until the food connected bags are folded and compressed into the folded and compressed body with the smallest volume, and its realization can fully automatically compress the folded package. Then, the second cylinder 113 in the side pushing assembly 11 pushes the second push plate 114 to push the connected bag folded and compressed body away from the platform 95 to the next working station. Thus, the folding and compression of the food connected bags are completed, and the food connected bags are convenient for subsequent packaging bag installation after being folded and compressed.

[0047] Its overall structural design realizes a series of operations, such as automatically conveying food continuous packages, automatically adjusting the height of the hanging rod 801 for hanging packages, automatically hanging food continuous packages with single packages of different lengths, automatically limiting the conveyance of food continuous packages and preventing the food continuous packages from arching, automatically folding down the next joint adjacent to the joint that folds the food continuous package upward, automatically limiting the joint that folds down the food continuous package falling into the groove 90 of the synchronous belt 94 in the double-sided synchronous conveyor belt 9 to shape the folded package formed by folding, automatically folding and compressing the food continuous package into a folded compression body with the minimum volume, and automatically pushing the folded compression body with the minimum volume to the next working station. It has the advantages of simple structure, high packaging efficiency, good packaging effect, low production cost, low packaging cost and easy maintenance. Moreover, its hanging package component 8 can realize hanging packages with only one connecting rod, and cooperate with the tail pushing component to compress the folded package in a relaxed state, so as to replace the problem that the existing food packaging equipment on the market uses the method of mutually closing multiple hanging rods 801 to compress the folded package, resulting in complex structure, high production cost, high maintenance cost and high packaging cost.

Any technical solutions that are the same as or equivalent to the content described in the claims of the present invention shall be included within the protection scope of the present invention.
