Description

Technical Field

[0001] This invention relates to the field of logistics system technology, and in particular to a solid alcohol packaging and transportation logistics system. Background Technology

[0002] Solid alcohol is a block-shaped fuel product formed by thickening and solidifying ethanol, methanol, or other combustible alcohols as the main fuel. It is characterized by its portability, stable combustion, and high safety during storage and transportation, and is widely used in catering heating, self-heating food, field operations, emergency rescue, military supplies, and industrial auxiliary heating. With the continuous growth of market demand, solid alcohol manufacturers are gradually developing towards large-scale, continuous, and automated production, placing higher demands on the production efficiency, packaging precision, and quality control capabilities of the downstream packaging and logistics systems.

[0003] Currently, the production of solid alcohol typically involves a series of processes including carton forming, product counting, packing, sealing, palletizing, and warehousing and transportation. Among these, the packing process is one of the most critical steps affecting production efficiency and packaging quality. Common packaging methods in the industry include manual packing, semi-automatic packing, and simple automatic unloading packing.

[0004] When packing by hand, workers need to count each piece of solid alcohol before placing it into a carton and then sealing it. This method is not only labor-intensive, but also prone to visual fatigue and counting errors due to prolonged repetitive work, resulting in inconsistent product quantities within the carton. Furthermore, the efficiency of manual operation is greatly affected by the number of workers and their skill level, making it difficult to meet the demands of continuous, high-speed production lines.

[0005] Some companies use semi-automatic packing equipment, which transports solid alcohol to the packing station via a conveyor system, and then relies on manual labor to sort the products and confirm quantities. While this can reduce labor intensity to some extent, it still depends on manual counting and quality judgment, resulting in a low level of automation and limited improvement in production efficiency. Furthermore, when the production cycle time increases, manual counting is prone to problems such as omissions and duplicates, leading to discrepancies in the number of boxes packed.

[0006] For existing automated packaging equipment, most machines use a continuous conveying and free-fall packing method, where solid alcohol is directly conveyed to the top of the carton via a conveyor belt and then falls into the carton. Because solid alcohol blocks are small and the conveying speed is high, accumulation, collisions, flipping, and overlapping easily occur during the falling process, resulting in a difference between the actual number of products entering the carton and the theoretical number. Especially when switching between producing multiple product specifications, traditional equipment struggles to quickly adapt to different packaging quantity requirements, leading to a decrease in packing accuracy.

[0007] Meanwhile, existing automated packaging production lines generally lack reliable single-item counting and quantitative control mechanisms. Although some equipment is equipped with counting sensors, the high product conveying speed or uneven spacing between products can easily lead to false triggers and missed detections, resulting in discrepancies between the counting results and the actual number of items packed. When abnormal packaging quantities occur, traditional equipment often cannot correct them in time during the packing process, relying solely on subsequent manual sampling to identify the problem, which not only increases quality management costs but also reduces production efficiency.

[0008] On the other hand, in the process of carton transportation, existing logistics transportation systems usually adopt a single transportation path structure, lacking an efficient logistics distribution mechanism between workstations. When multiple solid alcohol production equipment are running simultaneously, it is difficult to effectively match the material supply and carton transportation between different packaging workstations. This can easily lead to situations where some workstations are waiting for cartons and others are waiting for materials, resulting in uncoordinated production rhythm and affecting overall capacity utilization.

[0009] In addition, cardboard boxes also have the following problems during conveying, reversing, and transfer: (1) When the specifications of the carton change, the guide mechanism on both sides of the traditional conveyor line is inconvenient to adjust, and the carton is prone to offset, tilting or even jamming. (2) When the carton is switched between different conveyor lines, the conveying direction changes, which can easily cause the carton to collide, pile up or be interrupted. (3) After the carton is packed, it usually goes directly into the sealing process. There is a lack of effective online quality inspection methods, and it is impossible to detect packaging defects such as under-packing or over-packing in a timely manner. (4) For cartons with abnormal weight, most production lines require manual re-inspection and manual rejection, which not only increases labor costs but also affects the continuous operation of the production line.

[0010] Therefore, existing solid alcohol packaging and logistics systems generally suffer from technical problems such as low automation, insufficient precision in quantitative packing, weak online quality inspection capabilities, low efficiency in multi-station logistics coordination, and poor stability in carton conveying. How to construct a solid alcohol packaging and transportation logistics system that integrates automatic carton opening, automatic logistics allocation, precise counting and quantitative packing of solid alcohol, online weighing and inspection, automatic rejection of defective products, and automatic sealing, thereby achieving continuous, intelligent, and high-precision control of the packaging process, has become an urgent problem to be solved.

[0033] The logistics transportation system includes a first belt conveyor assembly 4, a second belt conveyor assembly 5, a third belt conveyor assembly 6, a fourth belt conveyor assembly 7, a first roller conveyor assembly 8, a material loading assembly 9, and a discharge hopper 10.

[0034] Case opener 1 ( Figure 13 A carton opener 1) is placed at point a) to process folded flat cartons into shaped empty cartons, and a first belt conveyor assembly 4 is provided at the lower end of the carton outlet.

[0035] Multiple material mounting components 9 are set at certain intervals along the upper edge of the first belt conveyor assembly 4.

[0036] Each solid alcohol packaging machine 2 ( Figure 13 At point b, a second belt conveyor assembly 5 is installed at the lower end of the solid alcohol outlet of the solid alcohol packaging machine 2). The output end of each second belt conveyor assembly 5 is connected to the inlet end of a material installation assembly 9.

[0037] Each material installation component 9 is equipped with a discharge hopper 10 at its outlet end, and a third belt conveyor component 6 is installed below each discharge hopper 10.

[0038] The input end of the multi-row third belt conveyor assembly 6 is arranged adjacent to the first belt conveyor assembly 4 and the conveying directions are perpendicular to each other. The output end of the multi-row third belt conveyor assembly 6 is arranged adjacent to the fourth belt conveyor assembly 7 and the conveying directions are perpendicular to each other.

[0039] The fourth belt conveyor assembly 7 is connected to the first roller conveyor assembly 8, and the first roller conveyor assembly 8 is equipped with a box sealing machine 3.

[0040] The belt conveying direction of the first belt conveyor assembly 4 is parallel to the belt conveying direction of the fourth belt conveyor assembly 7. The belt conveying direction of the second belt conveyor assembly 5 is parallel to the belt conveying direction of the third belt conveyor assembly 6. The belt conveying direction of the first belt conveyor assembly 4 is perpendicular to the belt conveying direction of the third belt conveyor assembly 6.

[0041] The second belt conveyor assembly 5 is mounted on the base frame 11, and its belt height is higher than that of the third belt conveyor assembly 6 to ensure that the solid alcohol can fall smoothly into the carton below.

[0042] Each material mounting assembly 9 includes a mounting frame 901, a material baffle 902, a cylinder 903, a housing 904, a first pin connecting rod 905, a second pin connecting rod 906, a first pin connecting block 907, and a second pin connecting block 908. The housing 904 is located above the mounting frame 901 and is connected to the edge of the second belt conveyor assembly 5. The housing 904 has a partition 909 inside, with a through discharge channel 910 between the two partitions 909. The space between the partitions 909 and the housing 904 is a mounting cavity 911. The second belt conveyor assembly 5 extends into the discharge channel 910. Two cylinders 903 are located in the mounting cavity 911, on either side of the second belt conveyor assembly 5. The piston rod of each cylinder 903 passes through the partition 909. A first pin 905 is longitudinally inserted through one end of the cylinder piston rod extending from the partition 909. The upper and lower ends of the first pin 905 are respectively pinned to one end of a first pin block 907. A second pin 906 passes through the pin holes at the other ends of both first pin blocks 907 and the pin hole of a second pin block 908. The second pin block 908 is fixedly connected to a material baffle 902, and the material baffle 902 is pinned to the partition 909. In the initial state, the two material baffles 902 are attached to the upper end of the belt of the second belt conveyor assembly 5 and are inclined, with a gap between the two material baffles 902 for only one solid alcohol to pass through.

[0043] Two material baffles 902 are located inside the outer casing 904. The outlet end of the outer casing 904 is provided with a discharge hopper 10, which is located below the output end of the second belt conveyor assembly 5.

[0044] When the piston rod of cylinder 903 extends or retracts, it drives the material baffle 902 to open and close through the pin connection mechanism, thereby controlling the solid alcohol to pass through one by one and counting.

[0045] The second belt conveyor assembly 5 is equipped with an optical fiber sensor 12 near the edge of the outer casing 904, which is used to count the number of solid alcohol blocks passing through the material baffle 902.

[0046] To prevent the cartons or solid alcohol from deviating during transport, the system is equipped with adjusting rod assemblies 13 at multiple locations.

[0047] Adjusting rod assemblies 13 are provided on both sides of the first belt conveyor assembly 4, but no adjusting rod assembly 13 is provided at the position corresponding to the mounting bracket 901. Adjusting rod assemblies 13 are provided on both sides of the second belt conveyor assembly 5. Adjusting rod assemblies 13 are provided on both sides of the third belt conveyor assembly 6. Adjusting rod assemblies 13 are provided on both sides of the fourth belt conveyor assembly 7, but no adjusting rod assembly 13 is provided in the area where it connects to the output end of the third belt conveyor assembly 6.

[0048] Adjusting rod assemblies 13 are respectively provided on both sides of the first roller conveyor assembly 8.

[0049] Each adjusting rod assembly 13 includes an adjusting seat 1301, an adjusting rod 1302, a fastener 1303, and an adjusting plate 1304. The adjusting seat 1301 has a transversely extending adjusting hole 1305 at its side end, and a threaded hole 1306 communicating with the adjusting hole 1305 at its upper end. The adjusting rod 1302 passes through the adjusting hole 1305, and the adjusting plate 1304 is mounted on the adjusting rod 1302, facing the middle of the belt of each belt conveyor assembly or the middle of the roller of the first roller conveyor assembly 8. The fastener 1303 is screwed into the threaded hole 1306, with its bottom end abutting against the adjusting rod 1302. Tightening the fastener 1303 fixes the extension length of the adjusting rod 1302.

[0050] Each mounting bracket 901 has a first jet seat 14 at its bottom, located on the outer edge of the first belt conveyor assembly 4 away from the third belt conveyor assembly 6. The first jet seat 14 is connected to an air supply device (not shown) via a pipe, and an air pump is installed on the pipe. Each first jet seat 14 has a first photoelectric sensor 15 at its upper end, used to detect whether an empty carton has reached below the material mounting assembly 9 on the first belt conveyor assembly 4.

[0051] A second photoelectric sensor 16 is provided at the upper edge of the third belt conveyor assembly 6 in each row. The second photoelectric sensor 16 corresponds to the outlet position of the discharge hopper 10 and is used to detect whether the empty carton has been in place.

[0052] A weighing device 17 and a second roller conveyor assembly 18 are provided between the fourth belt conveyor assembly 7 and the first roller conveyor assembly 8. The weighing device 17 includes a weighing frame (not shown in the figure), a conveyor belt 1701, a weighing idler (not shown in the figure), a weighing sensor (not shown in the figure), and a weighing display instrument 1702. The weighing idler is mounted on the weighing frame, the conveyor belt 1701 passes over the weighing idler, and the weighing sensor is located on the weighing frame. During the operation of the conveyor belt 1701, the weight of the conveyor belt 1701 itself and the weight of the material on the conveyor belt are transmitted to the weighing sensor through the weighing idler. The weighing sensor outputs a corresponding weight electrical signal to the weighing display instrument 1702 to realize weight detection and display.

[0053] A second jet seat 19 is provided on one side of the second roller conveyor assembly 18. The second jet seat 19 is connected to an air supply device through a pipe. An air pump is provided on the pipe to blow cartons that do not meet the weight requirements away from the main conveyor line.

[0054] The system also includes a controller (not shown in the figure). The controller's inputs are electrically connected to the load cell, the first photoelectric sensor 15, the second photoelectric sensor 16, and the fiber optic sensor 12, respectively. The controller's outputs are electrically connected to all the air pumps and cylinders 903, respectively.

[0055] Several steering wheels 20 are rotatably arranged on the upper edge of the fourth belt conveyor assembly 7. Each steering wheel 20 corresponds to the output edge of each third belt conveyor assembly 6 and is used to assist the carton in turning from the third belt conveyor assembly 6 to the fourth belt conveyor assembly 7.

[0056] The working principle of this invention is as follows: The carton opener 1 processes the folded flat carton into a shaped empty carton, and the shaped empty carton falls onto the first belt conveyor assembly 4, which then conveys it forward.

[0057] When the first photoelectric sensor 15 detects that an empty carton has arrived below the material mounting assembly 9, the controller controls the corresponding air pump to start, and the first air jet seat 14 sprays out gas to blow the empty carton from the first belt conveyor assembly 4 to the corresponding third belt conveyor assembly 6.

[0058] The third belt conveyor assembly 6 transports the empty carton to directly below the discharge hopper 10. After the second photoelectric sensor 16 detects that the empty carton has arrived, it sends a signal to the controller.

[0059] The solid alcohol packaging machine 2 sequentially conveys solid alcohol packaged in plastic film to the second belt conveyor assembly 5.

[0060] The controller controls the piston rod of cylinder 903 to open the material baffle 902. Solid alcohol passes through the gap between the material baffles 902 one by one and slides down the inclined material baffles 902 to the output end of the second belt conveyor assembly 5, and then falls into the empty carton below through the discharge hopper 10.

[0061] The fiber optic sensor 12 counts the number of solid alcohol blocks that pass through. When the count reaches the set value, the controller controls the piston rod of the cylinder 903 to move in the opposite direction, and the material baffle 902 returns to the initial closed state, stopping the material from falling.

[0062] The cartons containing a fixed amount of solid alcohol continue to move forward with the third belt conveyor assembly 6 until they reach the junction with the fourth belt conveyor assembly 7.

[0063] With the help of the steering wheel 20, the carton is reversed 90° and enters the fourth belt conveyor assembly 7, and then conveyed to the conveyor belt 1701 of the weighing device 17.

[0064] The weighing sensor converts the total weight of the carton and conveyor belt 1701 into an electrical signal and outputs it to the weighing display instrument 1702, while also transmitting the signal to the controller.

[0065] The carton continues to move forward into the second roller conveyor assembly 18. At the same time, the controller compares the actual weight with the preset standard weight: if the weight does not meet the standard (i.e. the amount of solid alcohol in the carton is incorrect), the controller controls the air pump corresponding to the second jet seat 19 to work, and sprays gas to blow the unqualified carton to the side that deviates from the conveyor track; if the weight meets the standard, the carton continues to move forward into the first roller conveyor assembly 8.

[0066] The cartons are conveyed on the first roller conveyor assembly 8 and sealed by the carton sealing machine 3 at the same time, thereby completing the packaging process of a set weight of solid alcohol in a single carton.

[0067] The first belt conveyor assembly 4, the second belt conveyor assembly 5, the third belt conveyor assembly 6, and the fourth belt conveyor assembly 7 all use commercially available conventional belt conveyors, and their specific structures will not be described in detail here. Similarly, the first roller conveyor assembly 8 and the second roller conveyor assembly 18 also use commercially available conventional roller conveyors, and their details will not be described in detail here either.

[0068] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention should fall within the protection scope of the present invention.
