[0031] The utility model will be described below in conjunction with the drawings of the embodiments of the utility model. Figures 1-6 The technical scheme in the embodiments of the utility model is described clearly and completely, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.

[0032] In order to solve the problems in the prior art, the embodiment provides a multi-bag type multi-film material collinear packaging production device, which comprises five parts:

[0033] The first part is a conveying system: comprising conveying belt one 1, the conveying belt one 1 end is equipped with reversible belt conveyor 5, the reversible belt conveyor 5 both ends are equipped with 90 ° turning belt conveyor 10, and the output ends of the two turning belt conveyors 10 are respectively connected with conveying belt two 2 and conveying belt three 3.

[0034] The conveying belt one 1, the conveying belt two 2, the conveying belt three 3, the reversible belt conveyor 5 and the turning belt conveyor 10 are all electric roller belt lines, and all include a conveying frame, bearings are embedded in the conveying frame at intervals on both sides of the conveying frame. The inner rings of a corresponding set of bearings are jointly embedded with a transmission shaft, so that the transmission shaft is rotatably installed on the conveying frame. The end portions of the transmission shafts on the same side are all fastened with sprockets, and the sprockets are jointly sleeved with a chain, forming chain transmission. All the transmission shafts are driven to rotate synchronously through the chain transmission, and the transmission of the chain transmission is stable, and the probability of slipping is greatly reduced compared with belt transmission. A belt is jointly sleeved on the transmission shafts, and the belt is frictionally matched with the transmission shafts, and the belt is driven to move along the length direction of the conveying frame through the rotation of the transmission shafts, forming a turn. The transmission shafts on the most side are connected to the speed regulating motor arranged on the side of the conveying frame through chain transmission again.

[0035] The speed regulating motor is an electric motor that can adjust and change the speed as required, and the speed is controlled by changing the frequency, current, voltage and the like of the motor. According to the principle of frequency regulation, the input frequency of the motor is changed to control the speed, and the speed is increased when the frequency is increased. The principle of voltage regulation is to control the speed by changing the input voltage of the motor, and the motor speed increases when the voltage increases; and the motor speed decreases when the voltage decreases. In the embodiment, a transformer is arranged between the speed regulating motor and the power supply, and the voltage is regulated through the transformer, thereby controlling the speed of the speed regulating motor.

[0036] The reversible belt conveyor 5 can convey in the forward direction and in the reverse direction, and is also called a forward and reverse belt conveyor. Its operating principle is also relatively simple, that is, a reversing mechanism is added between the output end of the speed regulating motor in the above belt transmission mechanism and the chain transmission of the transmission shaft, so that the belt can change the running direction as required.

[0037] The difference between the structure of the turning belt conveyor 10 and the conventional straight belt transmission is that the conveying frame and the outer extension surface of the belt of the turning belt conveyor 10 are both arc-shaped. Under the traction of the belt, the infusion bag 9 is subjected to the action of centrifugal force and moves along the curve, and finally enters the next straight section through the fence on the eaves of the conveying frame. The turning belt conveyor 10 is arranged between the two branch lines and the input line, so as to realize the turning conveying of the infusion bag 9 product at this station, so that the two branch lines and the input line are aligned, the occupied space of the whole production line is shortened, and the installation and arrangement of the production line are more reasonable.

[0038] The second part is a quality inspection system, which includes a plurality of groups of light inspection machines 4 arranged at intervals along the length direction of the conveying belt one.

[0039] The lamp inspection machine 4 is composed of a lamp inspection box, a lamp inspection table and a lamp inspection instrument. According to the principle of machine vision, a sequence image (qualified product image) of the qualified infusion bag 9 is shot by a camera and transmitted into a computer. Then, during the running of the production line, multi-directional imaging is carried out again by the camera on the lamp inspection machine 4, and the computer judges whether the liquid medicine contains visible impurities or not through a software algorithm. If yes, an instruction is sent out to sort out the substandard product through the PLC control; if no, the qualified product enters the next process.

[0040] The third part is a packaging system, which includes two sets of pillow packaging machines 7, and the input belts of the two sets of pillow packaging machines 7 are respectively connected with the output ends of the conveying belts two 2 and three 3.

[0041] The pillow packaging machine 7 is mainly composed of a feeding mechanism, a film feeding mechanism and a packaging mechanism. The feeding mechanism includes an input belt and a discharge belt, and the input belt and the discharge belt are arranged at intervals at the ends. The film feeding mechanism conveys two groups of films standing opposite to each other, and the starting end of the lower film is inserted into the output end of the conveying belt two 2 / conveying belt three 3 to ensure that the input belt on the conveying belt two 2 / conveying belt three 3 can fall onto the lower film. The lower film is attached to the input belt to provide support for the infusion bag 9 on the lower film. The upper film is finally covered on the infusion bag 9 under the traction of the guide roller. The cutter in the packaging mechanism is arranged between the input belt and the discharge belt, and the cutter is connected with a heating element. The infusion bag 9 wrapped by the upper film and the lower film moves to the front of the cutter, the input belt stops, the cutter cuts the film on the front side of the infusion bag 9 by heat pressing, that is, the upper seal; then the input belt starts to move the infusion bag 9 to the discharge belt, and the input belt and the discharge belt stop synchronously, and the cutter cuts the film on the back side of the infusion bag 9 by heat pressing, that is, the lower seal. The infusion bag 9 is completed packaging, and then is sent out by the discharge belt.

[0042] The fourth part is an alarm system, which includes one or more buzzer alarms arranged in each system. It is responsible for the alarm reminder when an abnormality occurs at each station.

[0043] The fifth part is a control part, which includes a PLC controller and three sets of camera identifiers 6. The three sets of camera identifiers 6 are arranged at the side of the conveying belt one 1 near one end of the reversible belt conveyor 5 and at the side of the two turning belt conveyors 10. The three sets of camera identifiers 6 are responsible for detecting the bag type of the infusion bag 9 and identifying the running conveying speed of the infusion bag 9. After identification, the data is transmitted to the PLC controller. The PLC controller is responsible for the signal, judgment, logical operation, output control of the belt running, the pillow packaging machine 7 running and the lamp inspection machine 4 running in the buoyancy system. So that the whole system is in an automatic control running state.

[0044] The upper computer touch screen control system is responsible for displaying the running state of the whole system, such as the running state of each station, the display of the packaging quantity of different varieties and different film materials, the running time, parameter adjustment, equipment failure, etc.

[0045] In the embodiment, two groups of U-shaped slides 8 are further included, the input ends of the two groups of slides 8 are respectively connected with the output ends of the corresponding pillow type packaging machines 7, and the output ends of the two groups of slides 8 are connected. The height of the two groups of slides 8 gradually decreases from the input end to the output end, forming a height difference. The packaged infusion bags 9 slide off from the slides 8 and slide out at the same place, realizing the centralized collection of the infusion bags 9.

[0046] In the embodiment, the lamp inspection machine 4 is a manual lamp inspection machine 4. The manual lamp inspection machine 4 mainly includes light, and the infusion bag 9 packaging defects and internal foreign matters are identified by human eyesight, and unqualified products are manually removed.

[0047] According to the above technical scheme, there are multiple use modes:

[0048] Mode 1: One product is divided into two same-speed running packaging. That is, after the qualified infusion bag 9 product after the lamp inspection machine 4 is identified by the camera recognizer 6 at the conveying belt one 1, when it is one type of bag, after logical operation of the PLC controller, the infusion bag 9 is conveyed to the reversible belt conveyor 5 by the conveying belt one 1, and then is alternately conveyed to the turning belt conveyors 10 on both sides by the reversible belt conveyor 5, and is conveyed to the two groups of pillow type packaging machines 7 by the conveying belt two 2 and the conveying belt three 3. Thus, the two groups of pillow type packaging machines 7 simultaneously package the same type of product, realizing even distribution packaging. Moreover, at the reversible belt conveyor 5, manual correction (when producing different types of products, there is a small probability that two types of products are incorrectly divided into two channels, so manual correction is set at this station) is not needed, so as to eliminate manual sorting, save labor, and save 50% of the single machine running time.

[0049] Mode 2: One product is divided into two different-speed running packaging. That is, after the qualified infusion bag 9 product after the lamp inspection machine 4 is identified by the camera recognizer 6 at the conveying belt one 1, when it is one type of bag, after logical operation of the PLC controller, the infusion bag 9 is conveyed to the reversible belt conveyor 5 by the conveying belt one 1, and then is alternately conveyed to the turning belt conveyors 10 on both sides by the reversible belt conveyor 5, and is conveyed to the two groups of pillow type packaging machines 7 by the conveying belt two 2 and the conveying belt three 3.

[0050] The running speed of the infusion bag 9 on each turning belt conveyor 10 is identified by the camera identifier 6 on the two turning belt conveyors 10, the relative speed of the running of the conveying system is calculated, the PLC reads the running speeds of the two sets of pillow packaging machines 7 and compares them, and the PLC controller is logically operated to determine that ① when the running speed of the camera identifier 6 and the pillow packaging machine 7 of the first path is slower than that of the camera identifier 6 and the pillow packaging machine 7 of the second path, the reversible belt conveyor 5 is automatically increased in running time by xx seconds (the actual PLC logical operation time) in the forward direction to realize the multi-distribution of the infusion bag 9 to the pillow packaging machine 7 of the first path for production. ② When the running speed of the camera identifier 6 and the pillow packaging machine 7 of the first path is slower than that of the camera identifier 6 and the pillow packaging machine 7 of the second path, the reversible belt conveyor 5 is automatically increased in running time by xx seconds (the actual PLC logical operation time) in the reverse direction to realize the multi-distribution of the infusion bag 9 to the pillow packaging machine 7 of the second path for production. The infusion bag 9 is distributed for pillow packaging according to the actual running speed, avoiding the influence of the different tempos of the speed fast and slow on the blockage of the conveying belt and the infusion bag 9.

[0051] Mode 3: Redundant configuration, which can also be backup for each other. That is, when the production line automatically produces and runs one kind of product, one set of the two sets of pillow packaging machines 7 and the matching conveying belt normally runs, and the other set is stopped. When the infusion bag 9 in any one of the two paths does not move or the pillow packaging machine 7 fails, the reversible belt conveyor 5 automatically switches and single-conveys to the pillow packaging machine 7 that does not fail to run, avoiding the production stop of the whole line due to the failure of a conveying belt or a pillow packaging machine 7. It can ensure that the production line continues to run without stopping production.

[0052] Mode 4: The production line automatically produces and runs two kinds of products with one kind of film material. After the product passes through the lamp inspection machine 4, it passes through the conveying belt one 1 and is identified by the corresponding camera identifier 6. When it is two kinds of bag types, after the PLC logical operation, the infusion bag 9 is conveyed to the reversible belt conveyor 5 from the conveying belt one 1, so that the same type of infusion bag 9 is conveyed to the same direction. And through the camera identifier 6 on the two turning belt conveyors 10, whether the bag type of the infusion bag 9 on each conveying belt is the same as the bag type set in the touch screen and the PLC. If the actual bag type is consistent with the set bag type in the program picture, the two sets of turning belt conveyors 10 run respectively. If not, the buzzer alarm will alarm and stop. The two kinds of bag type products are automatically distributed to the two sets of pillow packaging machines 7 for production, which can realize the same path quality inspection and separate packaging of the two kinds of products, breaking through the limitation that one line can only pillow package one kind of bag type product at the same time.

[0053] Mode 5: When two groups of products and two kinds of film materials are automatically produced, the two kinds of bag type infusion bags 9 are sent to the conveying belt one 1 after passing through the lamp inspection machine 4, and are identified by the corresponding camera identifier 6. When the two kinds of bag type are identified, the infusion bags 9 are sent to the reversible belt conveyor 5 through the PLC logical operation. The camera identifier 6 of the two groups of turning belt conveyors 10 identifies whether the bag type of the infusion bags 9 on the conveying belt is the bag type set in the touch screen and the PLC. The two groups of pillow type packaging machines 7 are respectively installed with different pillow packaging film materials. Through the formula logical operation set in the program, such as according to two kinds of bag type, two kinds of film material, through the respective conveying and time period conveying of the forward and reverse conveyor, through the formula setting in the PLC, the number of pillow packaging of different film materials, the number of different bag type and other corresponding combinations. It breaks through the simultaneous realization of packaging two kinds of bag type (such as bag type 1, 2), two kinds of outer packaging film (such as film material A, B) corresponding to four kinds of pillow packaging products (1A, 1B, 2A, 2B four kinds of pillow packaging products).

[0054] Mode 6: When the production line is discontinuous production, single channel operation. The infusion bags 9 of multiple bag types can be placed on the lamp inspection table at the same time, and the products pass through the lamp inspection machine 4. After the multiple different bag type products pass through the conveying belt one 1 and are identified by the corresponding camera identifier 6, the different bag types identified by the camera identifier 6 are classified and counted in quantity and sent to the next station through the PLC logical operation. Automatic statistics is realized, and quantity errors and deviations caused by manual point inspection are eliminated.

[0055] Mode 7: When the production line is discontinuous production, single channel operation. The infusion bags 9 of multiple bag types can be placed on the lamp inspection table at the same time, and the products pass through the lamp inspection machine 4. After the multiple different bag type products pass through the conveying belt one 1 and are identified by the corresponding camera identifier 6, the different bag types identified by the camera identifier 6 are classified and counted in quantity and sent to the next station through the PLC logical operation. Automatic statistics is realized, and quantity errors and deviations caused by manual point inspection are eliminated.

[0056] The above seven modes are identified by the three sets of camera identifiers 6 equipped after the infusion bags 9. After the infusion bags 9 are abnormally damaged, quantitatively packaged, and packaged in a certain bag type, the excess infusion bags 9, damaged, and abnormal products are removed at the position of the pillow type packaging machine 7.

[0057] The whole system realizes the functions of the seven different modes, and in the seven modes, any one mode can realize different production speed operation.
