[0031] Example

[0032] like Figures 1 to 17 As shown, the present invention is an intelligent counting and sorting production line, including a counting sensor 1, a height detection sensor 2, a counting pallet detection sensor 3, a push plate rear limit detection sensor 4, a pull-distance conveyor belt 5, a counting chain conveyor belt 6, a stacking conveyor belt 7, a pancake bag 8, an L-shaped baffle 9, a bag collection basket 10 for unqualified products, a qualified push plate cylinder 11, a counting pallet 60, and a roller 601.

[0033] The pull-distance conveyor belt 5 and the stacking conveyor belt 7 are respectively arranged on one side of the counting chain conveyor belt 6, the pull-distance conveyor belt 5 is arranged at the tail outlet of the packaging machine, the counting sensor 1 is arranged above the tail of the pull-distance conveyor belt 5, the qualified push plate cylinder 11 is arranged below the tail of the pull-distance conveyor belt 5, the qualified push plate cylinder 11 is provided with a push plate rear limit detection sensor 4, the roller 601 is installed on the counting and collecting pallet 60, the counting and collecting pallet 60 is vertically installed on the counting and collecting chain conveyor belt 6, the counting and collecting pallet 60 is provided with a counting and collecting pallet detection sensor 3, and the counting and collecting pallet detection sensor 4 is provided. The measuring sensor 3 is arranged below the qualified push plate cylinder 11, the counting chain plate conveyor belt 6 is vertically arranged at the tail outlet of the pull-distance conveyor belt 5, the counting sensor 1 and the push plate rear limit detection sensor 4 are electrically connected to the counting chain plate conveyor belt 6, the bag collection basket 10 for unqualified products is arranged below the counting chain plate conveyor belt 6, the stacking conveyor belt 7 is arranged at the lower side of the counting chain plate conveyor belt 6, the height detection sensor 2 is arranged above the entrance of the stacking conveyor belt 7, and the height detection sensor 2 and the counting pallet detection sensor 3 are electrically connected to the qualified push plate cylinder 11.

[0034] Specifically, the L-shaped baffle 9 is arranged at the tail of the tension conveyor belt 5 and on one side of the counting chain conveyor belt 6. The top of the L-shaped baffle 9 is at least ten millimeters higher than the tension conveyor belt 5. The L-shaped baffle 9, the counting chain conveyor belt 6, the tension conveyor belt 5, and the counting pallet 60 form a counting basket.

[0035] Specifically, the number of metering plates 60 installed on the metering chain conveyor belt 6 is not less than six, each metering plate 60 is installed with not less than five rollers 601, and the gap between two adjacent rollers 601 is not greater than five millimeters.

[0036] The intelligent counting and sorting production line of this embodiment also includes a programmable controller for controlling the actions of each actuator, including the motors, solenoid valves and circuits between electrical components required to execute the actions. Those skilled in the art can clearly know the installation and connection of these basic components and circuits based on the above description, which will not be repeated here.

[0037] Working method description:

[0038] During operation, the counting chain conveyor belt 6 first drives the counting pallet 60 to descend, and the counting pallet detection sensor 3 stops after detecting the counting pallet 60. At this time, there is just a counting pallet 60 parked at the bottom of the L-shaped baffle 9. At this time, the L-shaped baffle 9, the counting chain conveyor belt 6, the pulling conveyor belt 5 and the counting pallet 60 form a counting basket; when the packages of pancakes 8 coming out of the front packaging machine enter the pulling conveyor belt 5, the distance between the pancake packages 8 is pulled apart by the pulling conveyor belt 5, and the counting sensor 1 detects that each package of pancakes 8 has completely entered the counting pallet 60 at the bottom of the L-shaped baffle 9, the counting chain conveyor belt The conveyor belt 6 drives the counting and collecting pallet 60 to immediately descend the height of a pack of pancake packages 8 for stacking. When the counting sensor 1 detects that the number of pancake packages 8 that have completely entered the counting and collecting pallet 60 is exactly equal to the set number of packages, the counting and collecting pallet 60 carrying the counted and stacked pancake packages 8 descends along with the counting and collecting chain conveyor belt 6. The counting and collecting pallet detection sensor 3 just detects the counting and collecting pallet 60 and the counting and collecting chain conveyor belt 6 stops. At this time, another counting and collecting pallet 60 stops at the bottom of the L-shaped baffle 9. The height detection sensor 2 measures the height of the pancake package 8 on the counting and collecting pallet 60 that stops at the counting and collecting pallet detection sensor 3.

[0039] When the height detection sensor 2 measures that the stacking height of the pancake package 8 reaches the set height value, the stacking height of the pancake package 8 staying on the counting pallet 60 at the counting pallet detection sensor 3 is qualified, and the qualified push plate cylinder 11 is actuated to push the neatly stacked pancake package 8 on the counting pallet 60 to the stacking conveyor belt 7 and then immediately return it. Before the push plate rear limit detection sensor 4 detects that the qualified push plate cylinder 11 returns, the counting sensor 1 only counts the stacking each time it detects that a pack of pancake package 8 has completely entered the counting pallet 60 at the bottom of the L-shaped baffle 9. When the push plate rear limit detection sensor 4 detects that the qualified push plate cylinder 11 has returned, the counting chain plate conveyor The conveyor belt 6 drives the counting and collecting pallet 60 to immediately descend the total height of the currently counted stacked pancake packages 8. When the counting sensor 1 detects that the pancake packages 8 that have completely entered the counting and collecting pallet 60 are exactly equal to the set number of packages, the current counting and collecting pallet 60 carrying the counted and stacked pancake packages 8 descends along with the counting and collecting chain plate conveyor belt 6. After it descends to the counting and collecting pallet detection sensor 3 and just detects the counting and collecting pallet 60, the counting and collecting chain plate conveyor belt 6 stops. The height detection sensor 2 measures the height of the pancake packages 8 on the counting and collecting pallet 60 that is resting on the counting and collecting pallet detection sensor 3. When the height detection sensor 2 measures that the stacked height of the pancake packages 8 is less than When the height value is set, the stacking height of the pancake packages 8 on the counting pallet 60 is unqualified, and the qualified push plate cylinder 11 does not work. When the counting sensor 1 detects that a pack of pancake packages 8 has completely entered the counting pallet 60 at the bottom of the L-shaped baffle 9, the counting chain plate conveyor belt 6 drives the counting pallet 60 to correspondingly descend the height of a pack of pancake packages 8 for stacking. When the counting sensor 1 detects that the number of pancake packages 8 entering the counting pallet 60 is exactly equal to the set number of packages, the current counting pallet 60 carrying the counted and stacked pancake packages 8 descends with the counting chain plate conveyor belt 6 until the counting pallet detection sensor 3 has just detected the counting pallet 6 0, the counting chain conveyor belt 6 stops, and the height detection sensor 2 automatically measures the height of the pancake pack 8 on the counting and collecting pallet 60 resting on the counting and collecting pallet detection sensor 3, and the counting, stacking and sorting are carried out in this cycle. Unqualified pancake packs 8 are finally discharged into the unqualified pack collection basket 10 as the counting chain conveyor belt 6 descends; since the highly qualified pancake packs 8 pushed out to the stacking conveyor belt 7 have been neatly stacked, the workers do not need to collect and sort the products for boxing, and can directly put the neatly stacked pancake packs 8 into cartons; for bagged products, the stacking conveyor belt directly sends them to the packaging machine at the rear stage for automatic packaging.

[0040] It needs to be further explained that, in the process of the counting sensor 1 detecting and counting the stacked pancake packages 8, if the counting sensor 1 is affected by the outside world or the line contact is poor, such as a worker accidentally blocks the counting sensor 1 once, then when the number of stacked packages is set to 6, although the counting sensor 1 has counted 6 times which is equal to the set value, there are only 5 pancake packages 8 actually stacked on the counting pallet 60 this time. When the counting pallet 60 descends to the counting pallet detection sensor 3 and stops, the height detection sensor 2 automatically measures the height of the pancake packages 8 on the counting pallet 60. If the stacking height of the pancake packages 8 is less than the set height value, the qualified push plate cylinder 11 does not operate, and the pancake packages 8 on the counting pallet 60 are discharged into the unqualified package collection basket 10 as the counting chain conveyor belt 6 descends. If the stacking height of the counted stacked pancake packages 8 is less than the set height value for two consecutive times, the buzzer alarm will be used to remind the operator to confirm.

[0041] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0042] The above is a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
