An orderly full-automatic sterilization line for liquid strip bags

Abstract

The present invention discloses a fully automatic sterilization line for liquid strip bags, which includes an inner packaging area, a sterilization area, a first buffer area, a second buffer area, and a secondary packaging and boxing area, arranged in sequence. During the sterilization and transportation processes, the protection of products is more comprehensive, greatly reducing the loss of products during sterilization and transportation. In the entire line of equipment, the strip bags are always in an orderly state, and the large-scale turnover of the strip bags is achieved through a sterilization transfer device. The carriers containing the strip bags are installed on the sterilization transfer device in the form of N*N, and the entire line is transported orderly. Especially during sterilization in the sterilization cabinet, all-round protection of products can be achieved, and strip bags in different time periods will not be in the same sterilization cabinet. Since the packaging material of the entire line of strip bags is a roll film, equipment such as the lamp inspection machine, bottle washing machine, and bottle drying machine are removed, simplifying the entire line process, reducing the number of workshop personnel, and at the same time, due to the reduction of equipment with complex operations, the operation intensity and difficulty are greatly reduced.

Description

Technical Field

[0001] The present invention relates to the field of sterilization packaging production lines, and particularly to an orderly full-automatic sterilization line for liquid strip bags. Background Art

[0002] At present, most domestic liquid packaging products are bottled. The cost of the whole-line bottled consumables is relatively high. When the whole line runs automatically for sterilization, there are risks such as broken bottles. The whole line also needs to be equipped with a lamp inspection machine to detect broken bottles, leakage, etc., resulting in a large cost investment and a large floor area.

[0003] For example, the Chinese patent with the publication number CN206590875U discloses a beverage filling and disinfection control system, which includes a PLC controller and at least two filling production lines. The outlet of the filling production line is connected to a tunnel sterilization production line, and the end of the tunnel sterilization production line is connected to a coding and labeling machine. The PLC control system can comprehensively control multiple filling production lines, and enable multiple filling production lines to share the disinfection production line and the coding and labeling equipment. The PLC controller can control the frequency converter of the coding and labeling machine to set the conversion frequency of the coding and labeling machine, so as to label different products respectively, thus facilitating the control of the entire filling and disinfection process and improving production efficiency according to the actual production requirements of different filling products.

[0004] Another example is the foreign patent with the publication number RU63792U1, which discloses a food packaging and packaging line including a stage of rinsing containers before filling. The food filling and packaging production line includes conveyors, inlet and outlet containers, and is interconnected by an endless transport loop system to rinse the containers, fill the products into the containers and seal the containers. The transport loop consists of interconnected trolleys for gripping the containers that move in a first movement direction in a first process plane and return in a second movement plane parallel to the second movement direction. The system for rinsing the containers is located on the return movement of the transport loop in the second direction. This product can reduce the volume and area of the production line, reduce material consumption and operating costs, and improve the reliability of work.

[0005] For another example, a Chinese patent with the publication number CN1559880A discloses a beer filling process for plastic beer bottles. A blow molding machine and an ultraviolet sterilization device are added to the beer filling production line. The air top pressure of the existing beer filling production line is reduced from the original 4 - 5 Kg to within 2 Kg to relieve the pressure on the bottles. The beer liquid is instantaneously sterilized at a high temperature before filling to reduce or avoid the impact of the instantaneous high pressure generated inside the bottle due to high temperature on the plastic beer bottle. The process steps are as follows: a / Blow molding the bottle - Ultraviolet sterilization - Standby on the filling line; b / Instantaneous sterilization of the beer liquid before filling - Filling by the filling machine - Foaming and exhausting - Capping - Wine inspection - Rinsing with water - Air drying - Labeling - Heat shrink packaging - Storage in the warehouse. Compared with the prior art, the application technology of the plastic beer bottle in the beer filling line of the present invention has the characteristics of reasonable process, reduced production cost, reduced waste of water resources, environmental protection, prevention of bottle explosion accidents, and reduction of transportation pressure. It not only has good economic benefits but also good social benefits. Therefore, it has good promotion and application value.

[0006] Based on the deficiencies of the above prior art, the actual problems to be solved by the present invention are:

[0007] 1. Currently, if bottled is used as the consumable for liquid packaging, first, if the consumable is fragile such as glass, it may break at any time during transportation and sterilization.

[0008] 2. Secondly, if the bottled consumable is other consumables such as plastic, as described in the prior art with the publication number CN1559880A of the third document, it is particularly time-consuming and laborious to add equipment such as a blow molding machine for pre-sterilization preparation before sterilization.

[0009] 3. During the process of adding stoppers and sealing conventional glass bottles, a bottle washing machine + bottle drying machine + stopper adding machine, etc. are required accordingly. At the same time, after the product is sealed, cracks may appear in the glass bottle packaging, affecting production efficiency and wasting resources.

[0010] 4. Adding a lamp inspection machine is required to detect whether the bottled consumable leaks after containing the liquid, which is very complicated.

[0011] 5. How to solve the problems of large floor area of traditional equipment and inability to synchronize the work progress of front and back-end workers.

[0012] 6. At the same time, the disordered arrangement during transportation and sterilization will also increase the process of sorting in an orderly manner before secondary packaging. Summary of the Invention

[0013] In view of the deficiencies of the prior art, the present invention provides an automatic sterilization line for liquid strip bags in an orderly manner to solve the above problems.

[0014] To achieve the above objectives, the present invention is realized through the following technical solutions.

Especially when sterilizing in the sterilization cabinet, all-round protection of products can be achieved, and strip bags in different time periods will not be in the same sterilization cabinet; because the packaging material of the whole line of strip bags is a roll film, equipment such as a lamp inspection machine, bottle washing machine, and bottle drying machine are removed, simplifying the whole line process, reducing the number of workshop personnel, and at the same time, because the equipment with complex operations is reduced, the operation intensity and difficulty are greatly reduced; compared with the sterilization process of conventional hard packaging (such as glass bottles), the floor area of the whole line is only half of that of hard packaging, and at the same time, the equipment is reduced by about one-third, greatly reducing the investment in equipment and factory buildings; the strip bag packaging of the whole line uses a roll film packaging material, which is small in volume and storage space, and the storage and transportation costs of the packaging material are greatly reduced; through the cooperation of the first buffer area and the second buffer area, the whole line realizes the disconnection of the front and rear production processes, improving the operation efficiency of the whole line. At the same time, because the process connection is disconnected, the personnel management is more flexible. The whole line uses two buffer areas to separate the products produced on the current day and the previous day, physically avoiding the risk of batch mixing. At the same time, through this solution, the working hours of the front-end and back-end workshop operators can be synchronized, avoiding the situation where the back-end production personnel have to wait for the front-end production sterilization to be completed before starting production, and simplifying the shift management of the workshop; the zoning of the whole line is simple and clear (the high-humidity places in the sterilization area and the drying area are separated from the front and rear packaging sections), simplifying the design and planning of the factory building.

[0026] 1. The strip bags are arranged in an orderly manner during the transportation and sterilization process of the whole line. The protection of the products is more comprehensive during sterilization and transportation, greatly reducing the loss of products during sterilization and transportation. In the whole line of equipment, the strip bags are always in an orderly state (in inner packaging, sterilization, and secondary packaging). The large-scale turnover of the strip bags is realized through the sterilization transfer device, and the carriers loaded with strip bags are loaded on the sterilization transfer device in the form of N*N. The whole line is transported orderly. Especially when sterilizing in the sterilization cabinet, all-round protection of the products can be achieved, and strip bags in different time periods will not be in the same sterilization cabinet.

[0027] 2. Since the packaging material of the whole line of strip bags is a roll film, equipment such as the lamp inspection machine, bottle washing machine, and bottle drying machine are removed, simplifying the whole line process, reducing the number of workshop personnel. At the same time, because the equipment with complex operations is reduced, the operation intensity and difficulty are greatly reduced.

[0028] 3. Compared with the sterilization process of conventional hard packaging (such as glass bottles), the floor area of the whole line is only half of that of hard packaging, and at the same time, the equipment is reduced by about one-third, greatly reducing the investment in equipment and workshops.

[0029] 4. The strip bag packaging of the whole line uses a roll film packaging material, which is small in volume and storage space, and greatly reduces the storage and transportation costs of the packaging material.

[0030] 5. The whole line cooperates with Buffer Zone 1 and Buffer Zone 2 to disconnect the production processes before and after, improving the operating efficiency of the whole line. At the same time, due to the disconnection of the process association, the personnel management is more flexible. The whole line uses two buffer zones to separate the products produced on the current day and the previous day, physically avoiding the risk of batch mixing. At the same time, through this solution, the working hours of the operators in the front and back workshops can be synchronized, avoiding the situation where the back-end production personnel have to wait for the front-end production sterilization to be completed before starting production, simplifying the shift management in the workshop;

[0031] 6. The whole line is simply and clearly partitioned (the high-humidity places in the sterilization area and the drying area are separated from the front and back packaging sections), simplifying the design and planning of the workshop. Each functional area of the whole line solution is clearly distinguished, and targeted planning can be carried out according to the characteristics of each functional area. For example, the internal packaging has a higher purification level, the sterilization area has a higher humidity and temperature, and the external packaging has a lower purification level;

[0032] 7. The palletizing and depalletizing integrated machine includes a roadway vehicle, an integrated machine main body, and a pallet group. The three are combined and used together to realize the functions of depalletizing and palletizing the carrier in the three-dimensional space at the same time, saving the floor space of the equipment. The palletizing and depalletizing functions of the equipment are realized by the same power, with a simple, stable and reliable structure. At the same time, it also saves energy consumption, reduces the intensity of secondary sorting in the back-end and the equipment R & D cost. The equipment is equipped with upper and lower double-layer conveyors according to the processes of palletizing and depalletizing. Through the carrier buffer on the double-layer conveyor, while the front-end strip packages are loaded into the carrier, the back-end can perform the functions of palletizing or depalletizing. The process planning is more reasonable, the continuity of the whole line is better, and the stability is higher. After the strip bags are loaded into the carrier, the entire transfer and palletizing functions of the pallet group are realized. The transfer process is short and controllable.

[0070] A carrier detection photoelectric sensor 02091 is also provided on the upper conveyor 0209.

[0071] The tunnel vehicle 010 includes a lifting frame 0100, a lifting power mechanism 0101, a horizontal moving power mechanism 0102, and a telescopic fork 0103. The lifting frame 0100 is arranged on the lifting power mechanism 0101, and the lifting frame 0100 can move vertically up and down in the lifting power mechanism 0101. The lifting power mechanism 0101 is connected to the horizontal moving power mechanism 0102, and the lifting power mechanism 0101 can move horizontally on the horizontal moving power mechanism 0102. The telescopic fork 0103 is telescopically arranged on the lifting frame 0100.

[0072] The stack group 030 is composed of several pallets (also called carriers), which can accommodate and protect the transported liquid strip bags. The liquid strip bags on the pallet body can be arranged in order during transportation and sterilization, and the pallet body can be stacked, which can maximize the utilization rate of the sterilization equipment.

[0073] The main steps are as follows:

[0074] (1) The lane vehicle 010 uses the telescopic fork 0103 to lift the stack groups 030 (such as Figure 6 As shown), and sent to the unloading station in the integrated machine body 020 (as shown Figure 2 As shown), the lifting power mechanism 0101 of the lane vehicle 010 is synchronously used to lower the telescopic fork 0103 and the stack group 030 until the stack group 030 is placed on the unloading clamping device. The unloading low material level photoelectric 0207 receives a signal. At this time, the telescopic fork 0103 and the stack group 030 are disengaged, and the lane vehicle 010 synchronously retracts the telescopic fork 0103 to the origin and waits for the next instruction. At this point, the process of transporting N*N groups of stack groups 030 arranged in a single lane vehicle 010 is completed (as shown in FIG. Figure 8 shown);

[0075] (2) The unloading low material level photoelectric device 0207 of the integrated machine body 020 detects a signal, and the telescopic fork 0103 of the lane vehicle 010 is at the origin. At this time, the integrated machine body 020 performs the unloading process, and the lifting power device 0206 (such as Figure 9 As shown in the figure, the servo motor 02061 drives the crank 02063 to rotate, and the destacking lifting plate 0210310 is lifted by the power lifting connecting rod 02062, and the stacking group 030 is lifted by about 5-10mm. At this time, the destacking clamping device is opened (as shown in the figure). Figure 11As shown in the figure, the servo motor 02061 continues to work, the power lifting connecting rod 02062 lowers the height of about one layer of the stacking group 030, the unloading clamping device is closed, clamping the second to last layer of the stacking group 030 below, and then the servo motor 02061 returns to the origin, while returning to the origin, it drives the power unloading lifting plate 02064 and the single-layer stacking group 030 to descend to the lower conveyor 0211, and the whole single-layer unloading work is completed (the stacking action is the opposite process of the unloading action). If there is no signal detected by the unloading low material level photoelectric 0207 after completion, it indicates that the unloading has been completed and the step (1) process action needs to be repeated;

[0076] (3) The second separation cylinder 02102 is in the extended state by default (such as Figure 12 As shown), it is used to block the stack group 030 on the lower conveyor 0211. If there is no signal from the first lifting photoelectric 02106, the first lifting mechanism 021031 is at the origin position (as shown in FIG. Figure 13 As shown), and when the first separation detection photoelectric 02104 has a signal and the second separation detection photoelectric 02105 has a signal, the first separation cylinder 02101 extends to block the current stack group 030 and the subsequent stack groups 030, and so on, and the second separation cylinder 02102 retracts to release the current stack group 030, until a section of the lifting photoelectric 02106 has a signal, the second separation cylinder 02102 extends, and the first separation cylinder 02101 retracts, and the single stack group 030 separation process is completed;

[0077] (4) Following step (3), a lifting mechanism 021031 lifts the stack group 030 to a feeding or discharging position (e.g. Figure 14 As shown), the subsequent equipment or the preceding equipment scrapes the strip bag out of the main body of the stack group 030 by means of a scraper or a pusher, or pushes the strip bag into the main body of the stack group 030 (as shown). Figure 15 As shown), at the same time, the horizontal material receiving device 0213 extends (as shown Figure 17 As shown), after the scraping of the subsequent equipment is completed or the pushing of the previous equipment is completed, a section of the lifting mechanism 021031 returns to the origin. Since the horizontal receiving rod 02133 is under the lifting plate 0210310 (as shown in FIG. Figure 16 As shown in the figure, the gap left on the lifting plate 0210310 just avoids the horizontal material receiving rod 02133, so after a section of the lifting mechanism 021031 returns to the origin, the stack group 030 will remain on the horizontal material receiving rod 02133. Then the horizontal material receiving rod 02133 retracts and waits for the next step instruction;

[0078] (5) After the horizontal material receiving device 0213 retracts, the second-stage lifting device 0212 operates. The second-stage lifting chain 02123 drives the lifting blocks on both sides to lift upward. During the upward movement of the lifting blocks, they contact the stack group 030 and drive the stack group 030 to lift upward. When the lower surface of the stack group 030 is 110 mm higher than the upper material receiving rod 02081, the lifting stops. At the same time, the upper discharge mechanism 0208 operates (as Figure 20 shown). When the upper material receiving rod 02081 runs forward to directly below the stack group 030, it stops operating. At this time, the second-stage lifting device 0212 moves downward. After exactly placing the stack group 030 on the upper material receiving rod 02081, the second-stage lifting device 0212 is exactly in the original position. Subsequently, the upper discharge mechanism 0208 continues to operate until the stack group 030 is pushed to the upper conveyor 0209 (as Figure 19 shown), and then reciprocates back to the origin;

[0079] (6) As the stack group 030 is lifted and pushed from the lower conveyor 0211 to the upper conveyor 0209 one by one, the full-load carrier blocking cylinder 0203 is in the default extended state. When there is a signal from the 4-piece carrier detection photoelectric sensor 02091 and the palletizing lifting plate 0210310 is in the original position, at this time, the 4-piece carrier blocking cylinder 0201 extends to block the 5th carrier, and at the same time, the full-load carrier blocking cylinder 0203 retracts, sending carriers 1 - 4 into the palletizing station. When the presence / absence detection devices for carriers 1 - 4 in the palletizing station all detect signals, the full-load carrier blocking cylinder 0203 extends again, and at the same time, the 4-piece carrier blocking cylinder 0201 retracts. This above-mentioned action is repeated. When multiple presence / absence detection devices in the palletizing station all have signals, the full-load carrier blocking cylinder 0203 extends, indicating that the single-layer stack group 030 in the palletizing station is full, and then the palletizing process is carried out. The palletizing process shares the lifting mechanism with the unstacking process in step (1), so the actions are similar and will not be elaborated here. When there is a signal at the high palletizing level, the lifting mechanism of the roadway vehicle 010 operates, and together with the telescopic forklift 0103, the stacked N*N stack group 030 is taken into the lifting frame 0100 and then moved into the sterilization vehicle subsequently.

[0080] In the sterilization area, the strip bags delivered from the inner package are loaded into the pallet, and then the pallet passes through the first-stage lifting mechanism 021031 and the second-stage lifting device 0212 of the palletizing machine. The motor drives the synchronous belt to rotate, thereby driving the lifting connecting rod 0210314 to move. The lifting connecting rod 0210314 connects the upper and lower lifting plates 0210310, so that the lifting plate 0210310 can rise or fall. The lifting plate 0210310 lifts the upper pallet 030 to the clamping station. After the palletizing clamping device 0204 clamps the pallet, the lifting station is returned to the original state position to complete a single cycle. After multiple cycles, the pallet is stacked into a stack group 030 of N*N units, which is then extended by the telescopic fork 0103 of the lane vehicle 010. After the lifting power mechanism 0101 inserts the entire stacked stack group 030 of N*N units, the telescopic fork 0103 is retracted into the lifting frame 0100, and the stacked unit stack group 030 is transported to the corresponding sterilization transfer device by the translation force. The telescopic fork 0103 is also used to extend the telescopic fork 0103 of the lane vehicle 010. The retracting fork 0103 and the lifting power mechanism 0101 deliver the N*N unit stack group 030 from the palletizing station of the palletizing machine to the sterilization transfer device. The conveyor line delivers the sterilization transfer device into the sterilization cabinet for sterilization. After sterilization, the sterilization transfer device is sent to the buffer area 1 for air drying through the positioning transmission conveying mechanism in the new sterilization cabinet. After drying, the sterilization transfer device in the buffer area 1 is transported to the buffer area 2. There is equipment in the buffer area 2 to unload the N*N units on the sterilization transfer device into a single carrier, and then the strip bags on the carrier are sent to the regularization mechanism through the mechanism. After regularization by the regularization mechanism, they are sent to the cartoning machine for cartoning. In the whole line solution, the liquid strip bags are always in an orderly state (in inner packaging, sterilization, secondary packaging, etc.), and the large-scale turnover of the strip bags is realized by the sterilization vehicle, and the carriers with strip bags are installed on the sterilization vehicle in N*N form. The whole line is transported in an orderly manner, especially for sterilization in a sterilizer, which can achieve all-round protection for the product. There will be no situation where strip bags of different time periods are in the same sterilizer. Because the whole line uses buffer area 1 (with air drying function) and buffer area 2 to operate in coordination, the production correlation between the previous and next processes is disconnected, which greatly improves production efficiency. For example: On the first day, product a produced on working day A is transported to the sterilization cabinet in the sterilization conveyor 1 for sterilization. When the production on working day A is completed, all the products of the day will be transported to the drying channel through the conveyor line for drying. On the second day, product b produced on working day A+1 will also be transported to the sterilization cabinet for sterilization via the sterilization conveyor. At this time, product a has reached the boxing requirements after drying in the drying channel and is circulated in the buffer area 2 through the second conveyor (buffer area 2). At this time, the sterilization transfer device in the drying channel is transferred to the second conveyor, so the drying channel is empty at this time. The stack group 030 is taken out of the sterilization transfer device by the telescopic fork 0103 of the aisle vehicle 010 and placed in the palletizing machine. The carrier lifting feeding / discharging mechanism of the palletizing machine pushes the strip packages in the carrier into the regular steering device to realize the collection, sorting and steering of the strip packages, and then pushes them into the cartoning machine for boxing.If a fault occurs in the previous in-package filling area at this time, the product a in the latter buffer area two will continue to be disassembled, sorted and boxed, and at the same time, it will circulate internally according to the green arrow, and will not stop due to the fault in the previous process; if a fault occurs in the latter box-filling process, etc., the sterilization vehicle in the cyan area will continue to load the N*N carriers, and then go for sterilization. The sterilized product b can be stored in buffer area one (because the product a in buffer area one has been transferred to buffer area two), and the whole line will not stop due to the downtime of the latter equipment such as box-filling, greatly improving the efficiency of the whole line.
