Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical devices for packaging objects or materials of IPC classification B65B, and particularly relates to an innovative technology for a structurally improved packaging machine. The improved packaging machine is equipped with a simple and easy-to-use automatic online weighing device and a device for judging and rejecting defective and waste products based on the weighing device. Background Art

[0002] With the continuous advancement of technology and the expansion of application fields, packaging machines are widely used in many industries, such as food processing, pharmaceutical manufacturing, logistics distribution, etc. In these fields, packaging machines can effectively improve production efficiency, reduce labor costs, and enhance the reliability and aesthetics of product packaging.

[0003] In particular, the popularity of card entertainment game products has promoted the rapid development of related printing and packaging sub-industries and technologies. Card packaging machines are a type of mechatronic automatic machine based on this, which can automatically and accurately package complete sets of cards in a standardized and complex manner to protect their beauty. Card packaging machines are mainly divided into two categories: assembly line overall production packaging and product peripheral packaging equipment.

[0004] In the prior art, the disclosed automatic packaging machine equipment technology is limited. For example, patent application No. 202022487171.5 discloses an automatic packaging machine, including a support plate, a collecting wheel fixedly connected to the support plate, a turret fixedly connected to the collecting wheel, a control box fixedly connected to the side of the support plate, a gear fixedly connected to the support plate, a main conveyor belt in rolling contact with the gear surface, a conveying wheel provided at the upper end of the main conveyor belt, a pre-sealing device fixedly connected to the conveying wheel, a motor box fixedly connected to the lower end of the support plate, a base fixedly connected to the lower end of the motor box, a secondary conveyor belt fixedly connected to the side of the control box, one end of the secondary conveyor belt is rotatably connected to a rotating shaft, a ramp bracket fixedly connected to the rotating shaft, a feeding slope fixedly connected to the feeding slope, a feeding slope provided at the upper end of the secondary conveyor belt, a unloading conveyor belt provided at the other end of the secondary conveyor belt, a unloading trough fixedly connected to one end of the unloading conveyor belt, a finished product box provided at the lower end of the unloading trough, and a finished product box fixedly connected to one side of the control box.

[0005] Usually, since the unit price of a single printing and packaging product of this type of product is high, but the quantity is limited, it is rarely produced with full-process automatic equipment. Moreover, since the processing procedures and molds involved in each product are different, it is common to use a single-process production device at the production site. According to the product process needs, it is necessary to combine the processes in a modular manner. However, in this case, there is a lack of simple and easy-to-use online automatic weighing and waste rejection special devices, which requires manual operation for this important process, seriously restricting the overall production speed, reducing the packaging efficiency, and causing damage to the card product body due to manual misoperation.

[0006] Patent application No. 202120142374.2 discloses a waste collection and recycling device for a book-shaped box assembly machine, including a book-shaped box assembly machine body, a conveyor belt is provided on the book-shaped box assembly machine body, a drive groove is drilled on the book-shaped box assembly machine body, a screening mechanism is provided in the drive groove, and the screening mechanism includes a first support seat, a first support rod is connected to the first support seat, a first arc gear is sleeved on the first support rod, and a support plate is connected to the end of the first support rod away from the first support seat, and an upper contact piece and a lower contact piece are provided on one surface of the support plate. The deflated book-shaped boxes will be picked out during the transportation process and are not easy to be transported to the packaging position, so that the staff no longer need to perform selection and screening. It can be seen that online waste rejection of packaging equipment is an important process. However, the simple waste rejection technology suitable for brand packaging machines is less disclosed. Manual selection and screening are still required, which increases the workload of staff. In addition, the speed is extremely slow and the work efficiency is extremely low. In addition, manual selection and screening detection operations are prone to omissions and errors, resulting in the appearance of defective products, which damages the reputation of enterprises and distributors, and also brings economic losses to consumers and users while affecting their normal consumption experience. Utility Model Content

[0007] The technical problem to be solved by the utility model is that the existing weighing and rejecting process in the packaging process lacks corresponding mechanical devices. In view of the above problems and technical requirements, the utility model proposes an automatic weighing and rejecting improved packaging machine, which replaces manual operation with high speed, safety and reliability, automatically weighs the finished products after packaging, detects and rejects the finished products with abnormal weighing results due to over-packing or under-packing, so as to ensure the product quality.

[0008] The utility model comprises: a workbench, a feeding conveyor belt, a waste rejection push block, a purge pipe and a discharging conveyor belt; the feeding conveyor belt and the discharging conveyor belt are connected and installed in the same direction on the workbench; an automatic weighing station and an automatic waste rejection station are arranged on the workbench above or on both sides of the feeding conveyor belt or the discharging conveyor belt; a weighing table is installed on the workbench surface on the automatic weighing station, and the center of the weighing table is located in the moving direction of the feeding conveyor belt or the discharging conveyor belt; a waste rejection push block and a purge pipe are installed on the workbench surface on the automatic waste rejection station, that is, beside the feeding conveyor belt or the discharging conveyor belt; the forward moving direction of the waste rejection push block and the airflow blowing direction of the purge pipe are toward the feeding conveyor belt or the discharging conveyor belt.

[0013] The waste rejection power device is installed beside the waste rejection push block and the purge pipe.

[0014] The control cabinet is installed at the bottom or side of the workbench.

[0015] The finished product box is installed at the tail end of the discharge conveyor belt, that is, the rear end of the workbench, and an inclined finished product groove is opened at the edge of the workbench at this location; at the same time, a waste box is installed on the side of the workbench opposite to the waste rejection push block at the automatic waste rejection station, and an inclined waste groove is opened at the edge of the workbench.

[0016] By adopting the above technical solution, in particular, the automatic weighing station and the automatic waste rejection station are separated and arranged front and back along the moving direction of the feeding conveyor belt or the discharging conveyor belt; or, the automatic weighing station and the automatic waste rejection station are overlapped and combined into the same station and arranged centrally.

[0017] Compared with the prior art, the beneficial effects of the utility model are: through online weighing and timely launching of substandard packages, after the automatic weighing and rejection device is installed in the line, it can automatically identify and reject substandard products, thereby further ensuring the packaging quality to ensure that the number or weight of products in each package meets the preset standards. It overcomes the bottleneck link of manual inspection that unblocks the original production speed, improves the accuracy and consistency of packaging, and significantly improves the level of automated rapid packaging of the overall equipment of the packager. It improves packaging efficiency and reduces manual operations. The detection accuracy is guaranteed, thereby reducing the workload of staff and minimizing the probability of defective products.

DETAILED DESCRIPTION

[0022] It should be noted that:

[0023] If the word “a” or “an” appears in the present invention, it should be read as including one or at least one, and the singular form of elements or components also includes the plural form unless the number is obviously intended to be in the singular form.

[0024] In the description of the present utility model, the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The principle of the utility model is that, after the front printing, die-cutting, card sorting and card packaging, the materials are sent for positioning, packaging and labeling, and necessary online weighing and detection are performed before formal production. The dead weight of standard products is stable. If weighing abnormality occurs, it can be reasonably inferred that there is an erroneous packaging event in which components are missing or added. It can be further determined as waste and needs to be detected and rejected. Obviously, this process cannot detect single products with printing errors or wrong contents of the same dead weight. However, big data research shows that the proportion of weighing abnormalities in waste products exceeds 85%. Therefore, the detection and rejection problems can be basically solved through online automatic weighing and rejection. Other undetected defects can be visually assisted by the operator.

[0027] The utility model comprises: a workbench 1, a feeding conveyor belt 2, a waste rejection push block 7, a purge pipe 8 and a discharging conveyor belt 10.

[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The content of the present invention can be more easily understood by referring to the following preferred implementation method of the present invention and the embodiments included.

[0029] Embodiment 1: As attached Figure 1 As shown, a feed conveyor 2 and a discharge conveyor 10 are installed on the workbench 1 in the same direction; an automatic weighing station and an automatic waste rejection station are arranged on the workbench 1 above or on both sides of the feed conveyor 2 or the discharge conveyor 10; a weighing table 16 is installed on the surface of the workbench 1 on the automatic weighing station, and the center of the weighing table 16 is located in the moving direction of the feed conveyor 2 or the discharge conveyor 10; a waste rejection push block 7 and a purge pipe 8 are installed on the surface of the workbench 1 on the automatic waste rejection station, i.e., next to the feed conveyor 2 or the discharge conveyor 10; the forward moving direction of the waste rejection push block 7 and the airflow blowing direction of the purge pipe 8 are toward the feed conveyor 2 or the discharge conveyor 10.

[0030] In the above, a card wrapping station is arranged on the workbench 1, and a card wrapping device 3 is installed on the station. Specifically, the card wrapping device 3 is installed above the infeed conveyor belt 2 or the outfeed conveyor belt 10 at the front or rear of the workbench 1.

[0031] In the above, a weighing box 4 is installed on the automatic weighing station, and the weighing box 4 is mounted across the weighing platform 16.

[0032] In the above, the display control board 14 and the warning light 15 are installed on the automatic weighing station. Specifically, the display control board 14 and the warning light 15 are installed on the weighing box 4.

[0033] In the above, a drive box 9 is installed at the rear of the waste rejection push block 7 and the purge pipe 8.

[0034] In the foregoing, the detector 6 is installed beside the waste rejection push block 7 and the purge pipe 8.

[0035] In the foregoing, the waste rejection power device 5 is installed next to the waste rejection push block 7 and the purge pipe 8.

[0036] In the foregoing, the control cabinet 11 is installed at the bottom or side of the workbench 1.

[0037] In the above, a finished product box 13 is installed at the tail end of the discharge conveyor belt 10, that is, the rear end of the workbench 1, and an inclined finished product groove 12 is opened at the edge of the workbench 1 at this location; at the same time, a waste box 18 is installed on the side of the workbench 1 opposite to the waste rejection push block 7 at the automatic waste rejection station, and an inclined waste groove 17 is opened at the edge of the workbench 1 at this location.

[0038] In the embodiment of the utility model, the drive box 9 is powered by the motor or air pump of the waste rejection power device 5; the purge pipe 8 is powered by the air pump; the power source of the purge pipe 8 and the drive box 9 can be shared by the waste rejection power device 5, or the air pump power source of the purge pipe 8 can be installed separately in the control cabinet 11. Similarly, the waste rejection power device 5 can be installed in the control cabinet 11, on the workbench 1, or outside the control cabinet 11.

[0039] In the embodiment of the utility model, further, the weighing box 4 is not a necessary structure, and is mainly used to clearly mark the automatic weighing station. It can be replaced in parallel with a station bracket, a display board, or omitted. At this time, the display control panel 14 and the warning light 15 can still be installed on the simplified or replaced structure of the weighing box 4, or can be installed together or dispersedly on the workbench 1, or other parts.

[0040] In the embodiment of the utility model, the automatic weighing station and the automatic waste rejection station can be set separately in the front and back direction of the conveyor belt, or they can be combined into the same station and set centrally. In this case, the wrapped workpiece stays at the station and is first weighed automatically, and then rejected as needed. Furthermore, the wrapping device 3 can also be simplified in some scenarios. In this case, only the automatic weighing station and the automatic waste rejection station are set on the workbench 1, and no wrapping station is set.

[0041] In the embodiment of the utility model, there are two ways to connect the feed conveyor belt 2 and the discharge conveyor belt 10. One is to connect them into an integral conveyor belt; the other is to connect two sets of independent conveyor belts connected front and back, that is, the end of the feed conveyor belt 2 and the front end of the discharge conveyor belt 10 are respectively installed on the front and rear sides of the weighing platform 16 on the surface of the workbench 1 in the direction of movement of the conveyor belt.

[0042] Preferably, a transmission mechanism is installed in the drive box 9. A power supply device, a motor power device and an automatic control system device are installed in the control cabinet 11.

[0043] Preferably, the waste rejection power device 5 is an electric motor or an air pump device.

[0044] The implementation principle of this embodiment is:

[0045] 1) The product components enter the packaging device 3 from the feeding conveyor 2 installed on the workbench 1;

[0046] 2) The products processed by the labeling device 3 enter the weighing box 4 along the feeding conveyor belt 2. The products in the weighing box 4 are just located on the upper side of the weighing platform 16 and are weighed quickly. The weighing result is displayed on the display control board 14 located in the weighing box 4. The result of this data after being compared with the pre-stored preset standard value is also displayed on the display control board 14. If there is no abnormality, the product is loaded and moved out of the weighing box 4 by the discharging conveyor belt 10;

[0047] 3) The product after being removed from the weighing box 4 is placed on the discharge conveyor belt 10 and moves online to the position of the detector 6;

[0048] 4) Products weighed normally are loaded and moved forward by the discharge conveyor belt 10 to the end of the workbench 1, and then collected into the finished product box 13 by the finished product slot 12;

[0049] 5) For products with abnormal weighing, the warning light 15 lights up, and after being identified and recorded by the detector 6, the reject power device 5 servo-starts the drive box 9 to work, and the reject push block 7 moves forward to contact the abnormally weighed product to overcome the friction and push it to move horizontally. The purge pipe 8 only needs to apply a momentary slight air pressure to make the abnormal product laterally separate from the discharge conveyor belt 10 and enter the waste box 18 along the waste chute 17.

[0050] Preferably, the abnormally weighed products collected in the waste box 18 and pushed out from the discharge conveyor belt 10 need to be manually sorted and inspected later to maintain the sensitivity and accuracy of the online weighing-waste rejection mechanism.

[0051] Preferably, in the connection direction from the infeed conveyor belt 2 to the outfeed conveyor belt 10, the card wrapping device 3 can have two setting positions relative to the weighing-rejection process, namely: the first is that the card wrapping device 3 is set on the infeed conveyor belt 2 side of the weighing box 4, that is, the card wrapping is performed first and then the weighing and rejection is performed; the second is that the card wrapping device 3 is set on the outfeed conveyor belt 10 side of the latter section of the weighing-rejection process, that is, the weighing and rejection is performed first and then the card wrapping and output are performed. Select according to actual needs.

[0052] It can be seen that the complex and expensive equipment with automatic weighing and automatic rejection functions in the existing technology can be simplified at low cost to obtain more practical economic performance. Moreover, since installation, modification, replacement and maintenance are cheap and convenient, it is beneficial to the promotion and application in the industry. Combined with an intelligent management system, it can collect and analyze production data in real time, help enterprises realize the visualization and optimization of the production process, and improve the overall level of automation of the production process.

[0053] It should be noted that although the packaging machine with automatic weighing and rejection functions of the utility model can greatly improve production efficiency and product quality, it also needs regular maintenance and calibration during use to ensure long-term stable operation.

[0054] The above embodiments are only examples for more clearly explaining the technical solutions, and are not intended to limit the implementation methods of the present utility model. For those skilled in the art, other different forms of replacement or changes can be made based on the above description. This is to avoid exhaustively listing all implementation methods that are not necessary and cannot be fully listed. Therefore, the derived content may be within the scope of protection of the present utility model.
