Conveyors are used to transport food between each step. In addition, puffed food often requires multiple small bags to be neatly arranged and packed into large bags. Therefore, the bagging step also requires the arrangement and arrangement of small bags, the conveying and positioning of group bags, the supply and opening of large bags, the loading of small bags into large bags, and the sealing of large bags. The core lies in precise, stable and coordinated material handling and filling.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a conveying device and an energy-saving conveying method for food packaging.

[0036] Example 1: Please refer to Figure 1-Figure 4 , a conveying device, comprising a conveyor 1 for conveying small bag workpieces, wherein one end of the conveyor 1 is provided with a discharge port 2, and the discharge port 2 is connected to the surface of the conveyor 1 through a guide slope 3;

[0037] A workbench 4 is provided below the material discharge port 2, on which an arranging rack 5 and a driving assembly 6 are mounted, a packaging assembly 7 is provided on the edge of the workbench 4, and a plurality of semi-open cavity chambers 51 arranged in parallel are provided on the arranging rack 5, the semi-open cavity chambers 51 matching the width of the small bag workpiece, the driving assembly 6 is used to drive the semi-open cavity chambers 51 on the arranging rack 5 to move sequentially to the bottom of the material discharge port 2 to receive the small bag workpiece, the packaging assembly 7 includes a positioning sleeve 71 provided on the edge of the workbench 4, the positioning sleeve 71 is used to support the large packaging bag, and the driving assembly 6 is further used to drive the arranging rack 5 to move into the positioning sleeve 71, forcing the small bag workpiece in the arranging rack 5 to enter the large packaging bag;

[0038] When the conveyor 1 is running, the small bag workpiece is transported, and the guide slope 3 forces the small bag workpiece to turn over and fall from the discharge port 2;

[0039] When the driving assembly 6 is running, it first forces the arranging rack 5 to move to the bottom of the discharge port 2 in sequence, and collects and arranges the small bag workpieces through multiple half-open chambers 51. When the driving assembly 6 is running, it also drives the arranging rack 5 to move into the positioning sleeve 71, forcing the small bag workpieces on the arranging rack 5 to enter the large packaging bag.

[0040] The small bag workpiece in this embodiment is a small bag of food that has been packaged and inflated, and is placed flat on the surface of the conveyor 1. The semi-open cavity 51 is arranged in a rectangular parallelepiped shape, and has openings on the top and the side facing the positioning sleeve 71. The structure and function of the positioning sleeve 71 are conventional technologies of existing packaging machines and will not be described in detail.

[0041] When in use, the conveyor 1 is started, and the conveyor 1 conveys multiple small bags of food to the lower feeding port 2. The small bags of food slide down the guide slope 3 one by one, and then fall through the feeding port 2. In this process, the small bags of food are flipped and adjusted from flat to tilted. At the same time, after the driving component 6 is operated, it drives the arranging rack 5 to move intermittently toward the bottom of the lower feeding port 2, so that the half-open cavity chamber 51 moves to the bottom of the feeding port 2 in turn, so that the small bags of food fall into each half-open cavity chamber 51 respectively, and the shape of the small bags of food matches the shape of the half-open cavity chamber 51, so as to realize the arrangement and positioning of multiple small bags of food, and then the driving component 6 is started again. The driving component 6 drives the arranging rack 5 along the workbench 4 through the positioning sleeve 71, driving the multiple small bags of food to move after arrangement, and finally pushing the small bags of food into the large packaging bag sleeved outside the positioning sleeve 71, so that the small bags of food are evenly arranged in the large packaging bag, and finally starting the packaging component 7 to seal the large packaging bag;

[0042] By arranging a discharge port 2 and a guide slope 3 at the end of the conveyor 1, it is beneficial to flip the small bags of food into a tilted state. By arranging a driving component 6 and an arranging frame 5, the flipped small bags of food can be collected and arranged first, and then pushed into a large packaging bag. Finally, the large bag is sealed using the packaging component 7. This conveying method can arrange the small bags of food and then uniformly package them into large bags, which can prevent the small bags of food from tipping over or tilting due to their own center of gravity problems, thereby ensuring the stability of the bag-in-bag packaging process. It also has a simple and efficient structure and a high degree of automation.

[0043] Example 2: See Figure 5, different from the above embodiment, an outer baffle 8 and an inner baffle 9 are fixed at the output end of the conveyor 1, the discharge port 2 is located between the outer baffle 8 and the inner baffle 9, the bottom end of the guide ramp 3 is rotatably connected to the top edge of the inner baffle 9, and the top end of the guide ramp 3 is tangent to the end of the conveyor 1. The width of the discharge port 2 and the width of the semi-open cavity 51 match the thickness of the small bag workpiece.

[0044] The outer baffle 8 and the inner baffle 9 are both arranged vertically, and the bottom of the outer baffle 8 and the bottom of the inner baffle 9 are at the same height. When in use, when the small bag of food moves to the end of the conveyor 1, it slides down along the guide slope 3, and then falls vertically along the discharge port 2, so that the small bag of food is flipped from a flat state to a tilted state, which is conducive to the subsequent accurate arrangement of the small bag of food.

[0045] Example 3, see Figure 4-Figure 9 , different from the above embodiment, the driving assembly 6 includes a main slide 61 arranged just above the workbench 4, one end of the main slide 61 extends toward the positioning sleeve 71, a support leg is fixed on the main slide 61, a main slide 62 is provided on the surface of the main slide 61, a mounting frame 63 is fixed to the bottom of the main slide 62, a transverse slide 64 is fixed to one end of the mounting frame 63, one end of the transverse slide 64 extends toward the lower feed port 2, a transverse slide 65 is provided on the transverse slide 64, the arrangement frame 5 is fixedly connected to the transverse slide 65, and the driving assembly 6 also includes a longitudinal slide fixed to the bottom of the mounting frame 63 66. The longitudinal slide 66 is in the same direction as the main slide 61. A longitudinal slide 67 is provided at the bottom of the longitudinal slide 66. A base plate 68 is fixed to the bottom of the longitudinal slide 67. A strip plate 69 is provided on the side of the base plate 68 close to the arrangement frame 5. A plurality of insert tubes 610 are fixedly connected to one side of the strip plate 69. The plurality of insert tubes 610 respectively correspond to each semi-open cavity 51. The end of the insert tube 610 away from the strip plate 69 is inserted into the semi-open cavity 51 and is fixed with a push plate 60. A spring 611 is provided on the outside of the insert tube 610. The two ends of the spring 611 are respectively fixedly connected to the strip plate 69 and the arrangement frame 5.

[0046] Among them, in the initial state, the push plate 60 is in contact with the inner wall of the half-open cavity chamber 51, and the longitudinal slide 66, the main slide 61 and the transverse slide 64 are all configured as electric slides. When in use, the transverse slide 64 is started first. When the transverse slide 64 is running, the transverse slide 65 is driven to slide. When the transverse slide 65 slides, the arranging rack 5 is driven to move to the bottom of the lower feeding port 2, so that the half-open cavity chamber 51 is just moved to the bottom of the lower feeding port 2. When the small bag of food falls into the half-open cavity chamber 51, the transverse slide 64 is used to continue to drive the arranging rack 5 to move, so that each half-open cavity chamber 51 receives the small bag of food in turn. When all the half-open cavity chambers 51 receive the small bag of food, the transverse slide 64 drives the arranging rack 5 to reset, and then the main slide 61 is started. When the main slide 61 is running, the main slide 62 moves to the fixed position. When the positioning sleeve 71 moves, the main slide 62 drives the mounting frame 63, the transverse slide 64, the transverse slide 65, and the arranging rack 5 to move toward the positioning sleeve 71, so that the arranging rack 5 and the small bags of food are inserted into the positioning sleeve 71, and then the longitudinal slide 66 is started. When the longitudinal slide 66 is running, it drives the longitudinal slide 67 and the base plate 68 to move. The base plate 68 contacts the strip plate 69 and pushes the strip plate 69. When the strip plate 69 moves, it drives the insertion tube 610 and the push plate 60 to move, and also compresses the spring 611. When the push plate 60 moves along the inside of the semi-open oral chamber 51, it pushes the small bags of food, so that multiple small bags of food move to the outside of the arranging rack 5 at the same time. Finally, all the small bags of food leave the arranging rack 5 and enter the large packaging bag. Then the main slide 61 and the longitudinal slide 66 are started to reset the arranging rack 5.

[0047] By providing the main slide 61 and the transverse slide 64, it is convenient to drive the arrangement rack 5 to move, so that the arrangement rack 5 first receives a plurality of small bags of food and then pushes the small bags of food into the positioning sleeve 71. By providing the longitudinal slide 66 and the push plate 60 located in the arrangement rack 5, the longitudinal slide 66 drives the push plate 60 to move when it is in operation, and pushes the small bags of food in the arrangement rack 5 into the large packaging bag, which is convenient for automatically pushing the arranged small bags into the large bag.

[0048] Example 4, see Figures 9-11 , different from the above embodiment, the packaging component 7 also includes a bracket 72 arranged at the pipe mouth of the positioning sleeve 71, and a discharge channel 73 is fixed to the side of the bracket 72 away from the positioning sleeve 71. A fixer 74 for fixing the workpiece inside the large packaging bag and a welder 75 for sealing the mouth of the large packaging bag are provided on the top of the bracket 72. The welder 75 includes two groups of symmetrically distributed synchronous wheel driving members 751 installed on the inner side of the bracket 72, and a strip welding head 752 is fixed between the two groups of synchronous wheel driving members 751. Both ends of the strip welding head 752 are vertically slidably connected to the bracket 72.

[0049] Among them, one end of the discharge chute 73 is tilted downward, which helps the large packaging bag to slide. The packaged large packaging bag is pushed by the drive component 6 and discharged along the discharge chute 73. There is no need to use electric conveying equipment. The width of the discharge chute 73 matches the width of the large packaging bag. The synchronous wheel driving component 751 includes an upper synchronous wheel movably mounted above the bracket, a lower synchronous wheel movably mounted below the bracket, a synchronous belt connected between the upper synchronous wheel and the lower synchronous wheel, and a servo motor fixed on the bracket. The output end of the servo motor is fixed to the center of the lower synchronous wheel, and the synchronous belt is fixed to the strip welding head 752. When the servo motor is running, it can drive the synchronous belt to move, and then drive the strip welding head 752 to slide up and down. In use, when the small bag packaging enters the large packaging bag, it drives the fixer 74 and the welder 75. The fixer 74 fixes multiple small bags of food in the large packaging bag at the same time. When the welder 75 is running, the servo motor on the synchronous wheel driving component 751 is started, causing the strip welding head 752 to move downward, contact the large packaging bag, and weld and seal the large packaging bag.

[0050] Example 5, see Figure 7-10 , different from the above embodiment, the fixer 74 includes a vertical cylinder 741 fixed on the bracket 72, the output end of the vertical cylinder 741 faces downward and is fixed with a horizontal upper pressure plate 742, and the upper pressure plate 742 is fixed with a vertical side pressure plate 743 on the edge of the positioning pipe mouth. The push plate 60 includes a flat shell 601 at the bottom and a plug plate 602 at the top. The side wall of the flat shell 601 is fixed to the end of the plug tube 610, and the bottom of the plug plate 602 is inserted into the inner cavity of the flat shell 601. A vertical groove 603 is opened on the surface of the plug plate 602, and the edge of the vertical groove 603 is set There is a rack 604, and the cannula 610 is internally rotatably connected to a base shaft 605. One end of the base shaft 605 extends into the vertical groove 603 and is fixed with a gear 606. The gear 606 is engaged with the rack 604. The other end of the base shaft 605 passes through the strip plate 69 and is fixed with a worm gear 607. Two symmetrically distributed base blocks 608 are fixed on the strip plate 69. A worm 609 is movably connected between the two base blocks 608. The worm 609 is engaged with the worm gear 607. A drive motor 600 is fixed on one of the base blocks 608, and the output shaft of the drive motor 600 is fixed to the end of the worm gear 609.

[0051] Among them, the worm 609 is meshed with multiple worm gears 607 at the same time. When in use, after the push plate 60 pushes multiple small bags of food into the large packaging bag, the fixer 74 is started. At this time, the vertical cylinder 741 extends, driving the upper pressure plate 742 and the side pressure plate 743 to move downward. When the side pressure plate 743 moves downward, it squeezes the large packaging bag and moves to the side of the inserting plate 602 away from the small bags of food. Then the drive motor 600 is started. When the drive motor 600 is running, it drives the worm 609 to rotate. When the worm 609 rotates, it drives multiple worm gears 607 to rotate. When the worm gear 607 rotates, it drives the base shaft 605 and the gear 606 to rotate. When 606 rotates, it drives the rack 604 to move downward, thereby driving the entire inserting plate 602 to move toward the inside of the flat shell 601. When the height of the inserting plate 602 is less than the bottom of the side pressure plate 743, the longitudinal slide 66 and the main slide 61 can be started to move the arrangement rack 5 and the push plate 60 back to their original position. At this time, the side pressure plate 743 is located on one side of the multiple small bags of food. The vertical cylinder 741 extends again, driving the upper pressure plate 742 and the side pressure plates 743 to continue to move downward, so that the upper pressure plate 742 presses on the top of the small bag of food and the side pressure plates 743 are completely blocked by the side of the small bag of food. Finally, the welder 75 is started to perform the welding work.

[0052] By setting the push plate 60 as a flat shell 601 and a retractable insert plate 602, and setting the fixer 74 as a side pressure plate 743 and an upper pressure plate 742 that can move vertically, before welding, the side pressure plate 743 is first driven to move down to the side of the push plate 60, and then the push plate 60 is driven to first retract and then separate from the small bag of food, and finally the side pressure plate 743 is continued to move down to the side of the small bag of food. This method can block the end of the small bag of food before welding. Compared with the existing technology, it avoids the strip welding head 752 contacting the edge of the small bag of food when welding a large packaging bag, thereby avoiding the situation where the small bag and the large bag are welded together, thereby improving the packaging quality.

[0053] Example 6, see Figure 5 , different from the above embodiment, a sensor 10 for detecting blockage inside the discharge port 2 is fixed on the outer baffle 8, and an oblique cylinder 11 for driving the guide ramp 3 to rotate is installed on the outer wall of the inner baffle 9. The two ends of the oblique cylinder 11 are hinged to the inner baffle 9 and the guide ramp 3 respectively. An angle steel 12 is also provided on the top edge of the outer baffle 8, and a third vertical cylinder 13 is fixed on the angle steel 12. The output end of the third vertical cylinder 13 faces the discharge port 2 and is fixed with a push block 14.

[0054] The sensor 10 is an infrared sensor. When the small bag of food slides smoothly down from the discharge port 2, it blocks the infrared light for only a short time. When the small bag of food is locked at the discharge port 2, the oblique cylinder 11 and the third vertical cylinder 13 are activated. When the oblique cylinder 11 extends, it pushes the guide slope 3, causing the guide slope 3 to gradually rotate to a vertical state, so that the small bag of food stranded on the guide slope 3 moves into the discharge port 2. When the third vertical cylinder 13 extends, it drives the push block 14 to move downward and insert into the discharge port 2, pushing the small bag of food in the discharge port 2 downward, causing it to fall.

[0055] By setting up the sensor 10, the third vertical cylinder 13, the push block 14 and the oblique cylinder 11, when the sensor 10 detects that the small bag of food is blocked in the discharge port 2, the blocked small bag of food can be pushed out of the discharge port 2 by driving the guide slope 3 to rotate and driving the push block 14 to move downward into the discharge port 2, thereby avoiding the blockage of the discharge port 2 and affecting the subsequent packaging work.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
