Description

Technical Field

[0001] The utility model belongs to packaging machinery, in particular to a counting and sorting mechanism of a strip bag elevator. Background Art

[0002] Currently, pharmaceuticals such as granules and liquid solutions, as well as foods like milk powder and coffee, are typically packaged in back-seal strip bags. These are packaged into individual strip bags using a back-seal strip bag packaging machine. A subsequent sorting machine then sorts and conveys the bags. A weighing module marks any unqualified items, which are then removed by a reject mechanism. Acceptable items are then conveyed to the conveyor belt of the packaging line. Because the exit of the back-seal strip bag packaging machine is at a height difference from the entrance of the subsequent cartoning machine, an elevator is added to the line to elevate the material. A counting and sorting mechanism counts and sorts the back-seal strip bags, arranging them into the required number of bags for subsequent cartoning. These bags are then placed in the same hopper for subsequent cartoning and packaging.

[0003] Existing lifting and counting systems for back-seal strip bags mostly utilize cam-operated lifting and single-track stock counting. The cam-operated lifting system alters the line layout, changing the straight line to a 90-degree angle, increasing the space available for the line. Single-track stock counting systems sequentially push back-seal strip bags from the back-seal packaging machine onto a stocking plate for storage. When the material on the stocking plate meets the requirements for downstream packaging, the corresponding amount of material is pushed onto the counting plate. This structure suffers from low counting and sorting efficiency and a complex mechanism, impacting the production capacity of the front-end back-seal strip bag packaging machine.

The driving wheels at the lower right corners of the two groups of lifting synchronous belt assemblies share a driving shaft and one end of the driving shaft is connected to a stepper reduction motor arranged on one side of the machine body.

[0031] like Figures 1-9 As shown, the utility model relates to a counting and sorting mechanism for a strip bag elevator, comprising a strip bag elevator, wherein the strip bag elevator comprises a rectangular body 1 formed by a combination of metal plates, and two groups of lifting synchronous belt assemblies 2 arranged in a rectangular shape are symmetrically provided on both sides of the body 1, each group of lifting synchronous belt assemblies 2 comprises a driving wheel 17 and three driven wheels 11, wherein the driving wheel 17 is located in the lower right corner, and the remaining three driven wheels 11 are respectively installed on the side plates on both sides of the body 1 through wheel axles and bearings; the driving wheels 17 at the lower right corner of the two groups of lifting synchronous belt assemblies 2 share a driving shaft and one end of the driving shaft is coaxially connected to a stepping reduction motor 6 provided on one side of the body 1, and a plurality of silo seat plates 3 are evenly connected between the synchronous belts of the two groups of lifting synchronous belt assemblies 2, and a plurality of groups of strip bag silos 4 are evenly fixed on the silo seat plates 3. This embodiment takes 10 groups of strip bag silos as an example and each group of strip bag silos has 6 material troughs for loading strip bags and continuously lifting them to the height of the sorting plate.

[0032] A pair of longitudinal guide wheels 7 and a transverse guide wheel 8 are installed at both ends of the silo base plate 3 through short shafts, and two transverse guide rails 9 arranged up and down and two longitudinal guide rails 5 arranged left and right are fixed on the side panels on both sides of the body 1. When the bag elevator is running, the longitudinal guide wheels 7 are respectively inserted into the sliding grooves of the transverse guide rails 9 or the longitudinal guide rails 5 to ensure that the bag silo 4 is arranged horizontally when it is lifted in the vertical direction; the transverse guide wheels 8 are respectively against the inner ends of the transverse guide rails 9 or the longitudinal guide rails 5 to ensure the transverse position of the bag silo 4 when it rotates in a cycle.

[0033] A support plate 16 is fixed in the middle of the body 1 of the bag elevator. The support plate 16 is fixed between the side plates on both sides of the body 1. A sorting plate 22 is supported above the support plate 16 by a number of pillars 21. A plurality of sorting channels 221 are provided on the sorting plate 22. Each sorting channel has a plurality of bag chutes 222. A plurality of grouping chutes 224 are formed on the front end of the sorting plate 22 by a plurality of pairs of limit plates 24. The grouping chutes 224 correspond to the sorting channels one by one and are used to temporarily store the sorted groups of bag.

[0034] In this embodiment, there are six groups of sorting channels 221, and each group of sorting channels has 10 bag chutes. Each bag chute 222 is in a broken line shape, and two adjacent bag chutes are separated by a partition 223, and the lengths of the hypotenuses of two adjacent partitions 223 are different.

[0035] A support frame 12 is fixed within the machine body 1, below the support plate 16. A synchronous belt mechanism 20 driven by a servo motor 18 is mounted on the support frame 12. Two slides 32 are slidably mounted on the support plate 16 via two symmetrically arranged guide rails 37. A sliding frame 33 is provided above the finishing plate 22. Two support plates 31 connect the two ends of the two slides 32 to the two ends of the two slides 32. The bottoms of the two slides 32 are connected to the synchronous belt of the synchronous belt mechanism 20, driving the slides 33 to slide back and forth. A slat 38 is connected to the middle of the bottom surface of the two slides 32. A U-shaped clamp 19 is connected to the synchronous belt of the synchronous belt mechanism 20 via a clamping plate. The U-shaped clamp 19 and the slat 38 are fixedly connected by screws.

[0036] The sliding frame 33 is composed of two side panels and multiple connecting plates connected between the side panels. Multiple rotatable scraper frames 26 are evenly distributed on the sliding frame 33 via rotating shafts 25. A scraper cylinder 30 is hinged to one side of the sliding frame 33. The piston rod of the scraper cylinder 30 is connected to one end of the corresponding rotating shaft via a swing arm 29. The swing arm 29 is clamped to one end of the rotating shaft at the feed end of the corresponding sorting plate 22. The piston rod of the scraper cylinder 30 is hinged to the upper end of the swing arm 29 to adjust the angular position of the scraper frames 26. The multiple rotating shafts 25 are interconnected by multiple connecting blocks 27 and a connecting plate 28. One end of the connecting block 27 is clamped to one end of the corresponding rotating shaft 25. The connecting plate 28 is connected to the other end of the multiple connecting blocks 27 via evenly distributed bearings and short shafts, enabling the synchronous rotation of the multiple scraper frames 26.

[0037] This embodiment takes four scraper frames 26 as an example, and both ends of the rotating shaft 25 are respectively mounted on the sliding frame 33 through bearings. The scraper frame 26 is composed of a scraper and three clamping blocks evenly connected to the scraper, wherein the clamping blocks are sleeved and fixed on the rotating shaft 25 by screws.

[0038] A rotatable push plate frame 23 is installed on the sliding frame 33 near the front end of the sorting plate 22 through a rotating shaft. The push plate frame 23 has the same structure as the scraper frame 26 and is used to push the sorted groups of strip bags to the rear-end in-line conveyor belt; a push plate cylinder 34 is hinged on one side of the sliding frame 33, and the piston rod of the push plate cylinder 34 is connected to one end of the rotating shaft corresponding to the push plate frame 23 through a swing arm, which is used to adjust the position of the push plate frame 23 to achieve reciprocating pushing.

[0039] A pusher cylinder 14 is mounted on the body 1 at the loading end of the bag elevator at a height corresponding to the finishing plate 22 via a cylinder base plate 13. The pusher cylinder 14 is a double cylinder with a pusher plate 15 connected to one end of its piston rod. The pusher cylinder 14 is used to push the bag lifted by the bag elevator onto the finishing plate 22. Guide blocks 35 are fixed to both ends of the cylinder base plate 13, and guide posts 36 are symmetrically connected to both ends of the pusher plate 15, and the guide posts are respectively inserted into the corresponding guide blocks 35.

[0040] During installation, insert the rear section inline conveyor belt 10 into the machine body 1 and close to the front end of the finishing plate 22. During operation, the specific steps are as follows;

[0041] 1. The strip bag materials are conveyed to one end of the inlet of the strip bag elevator via the front-section inline conveyor belt. The bag replenishing and pushing mechanism located outside the inlet of the strip bag elevator pushes the 60 strip bags on the front-section inline conveyor belt into the 10 groups of strip bag silos 4 on the corresponding silo base plate 3, thus realizing intermittent feeding of the strip bag silos 4.

[0042] 2. The stepper reduction motor 6 of the bag elevator is started, and each silo base plate 3 and multiple groups of bag silos 4 are driven to move upward in a cycle through two sets of lifting synchronous belt assemblies 2. Each time the bag silos 4 move up to the height of the sorting plate 22, the stepper reduction motor 6 is paused, and the pushing cylinder 14 is started, and the bag materials in the bag silos 4 are pushed into the six groups of sorting channels on the sorting plate 22 through the pushing plate 15;

[0043] 3. Start the servo motor to drive the sliding frame 33 to slide back and forth through the synchronous belt mechanism 20; when the sliding frame 33 slides to the feeding end close to the sorting plate 22, the scraper cylinder 30 and the push plate cylinder 34 are controlled to extend, pushing the scraper frame 26 and the push plate frame 23 to flip and fall close to the sorting plate 22. As the sliding frame 33 slides, the strip bag materials can be scraped forward through the six groups of sorting channels to achieve group counting and sorting; each time the strip bag materials are scraped forward a certain distance by the scraper frame 26, the scraper cylinder 30 and the push plate cylinder 34 are quickly reset, thereby driving the scraper frame 26 and the push plate frame 23 to lift and move away from the sorting plate 22, thereby preventing the scraper frame 26 and the push plate frame 23 from carrying the strip bag materials behind when the sliding frame 33 is reset;

[0044] 4. When 60 strip bags are delivered to the multiple grouping chutes 224 at the front end of the sorting plate 22 by the scraper frame 26, the push plate frame 23 can push the sorted six groups of strip bags to the rear section of the inline conveyor belt, and the sorted strip bags can be continuously output by the operation of the inline conveyor belt.

[0045] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
