Abstract
Description
Technical Field
[0001] This utility model relates to the field of dairy processing equipment, and in particular to a lid-printing system for dairy product packaging cups. Background Technology
[0002] In dairy product processing and production, it is usually necessary to mark the packaging surface with identifying text or patterns, such as production date, batch number, and expiration date, to meet the needs of product traceability and anti-counterfeiting.
[0003] The traditional process for labeling and coding cup-packaged dairy products is as follows: First, the dairy product is filled into the cup; then, a cap film is fixed to the cup opening and coded; next, the cup is conveyed to a capping machine for capping; after that, a second code is coded on the cap; finally, the packaged dairy product is sent to the next processing stage. However, in actual production, occasionally uncapped defective products appear. These uncapped products are still incorrectly coded when passing through the cap coding machine, resulting in double coding on the cap film, thus classifying the product as defective. This leads to a high defect rate and, in severe cases, may cause quality complaints, thereby increasing production costs. Utility Model Content
[0004] The purpose of this invention is to overcome the problem that the failure to promptly detect uncapped dairy products in the existing technology leads to a high rate of defective products and even quality complaints. This invention provides a capping and coding system for dairy product packaging cups. This system allows for the effective identification of uncapped products as soon as they are moved to the capping coding machine, enabling timely response, reducing the rate of defective products, controlling costs, and facilitating widespread use.
[0005] In a first aspect, this utility model provides a lid-printing system for dairy product packaging cups.
[0006] A lid-mounting coding system for dairy product packaging cups includes the following structure:
[0007] A capping device for capping dairy product packaging cups;
[0008] The first main transmission channel is connected to the outlet of the capping device and is used to receive and transport the capped dairy product packaging cups.
[0009] The first coding device is positioned above the first main transmission channel and is used to print codes on the lid of the dairy product packaging cup.
[0010] A sensing device is disposed on the side of the first main transmission channel between the capping device and the first coding device; the sensing device is used to detect whether the dairy product packaging cup has been capped, and the sensing device is connected to an alarm unit.
[0011] This utility model relates to a capping and coding system for dairy product packaging cups. Its structure includes a capping device, a first main conveying channel, and a first coding device located above the channel, all connected in sequence. Furthermore, a sensing device is provided on the side between the capping device and the first coding device. During operation, the dairy product packaging cups move along the first main conveying channel after being discharged from the capping device. When passing the sensing device, if an uncapped cup is detected, the sensing device will issue an alarm through an alarm unit, prompting the worker to handle the situation. For capped packaging cups, the system continues to be conveyed to the first coding device for cap coding. This system allows for effective identification of uncapped products as soon as they reach the cap coding device, enabling timely response, reducing defective product rates, controlling costs, and facilitating widespread adoption.
[0012] As a preferred embodiment of this utility model, the sensing device includes an infrared sensor, an ultrasonic sensor, or a laser sensor.
[0013] As a preferred embodiment of this utility model, the height of the sensing device is adjustable. The adjustable height of the sensing device can accommodate products of different heights. The height of the sensing device is within the height range of the lid of the covered dairy product packaging cup. When the covered dairy product packaging cup passes the sensing device, the signal emitted by the sensing device encounters the lid and responds, indicating the presence of a lid. When the uncovered dairy product packaging cup passes the sensing device, the signal emitted by the sensing device does not encounter the lid and does not receive a response, indicating the absence of a lid, and the sensing device issues an alarm.
[0014] The height of the sensor is adjustable to accommodate lids of products of different heights, ensuring that the sensor can accurately detect whether packaging cups of various sizes are covered.
[0015] As a preferred embodiment of this utility model, a first guardrail assembly is provided on the side of the first main transmission channel. The provision of the first guardrail assembly can better protect the transportation safety of the product.
[0016] As a preferred embodiment of this utility model, a lateral transmission channel is connected to the side of the first main transmission channel between the sensor and the first coding device.
[0017] A redirection mechanism is provided at one end of the lateral transmission channel near the first main transmission channel. The redirection mechanism is used to redirect the dairy product packaging cups on the first main transmission channel to the lateral transmission channel.
[0018] In use, when the sensor detects that the passing product is an uncapped dairy product packaging cup, the redirection mechanism is activated, redirecting the dairy product packaging cup on the first main transport channel to the lateral transport channel, and then the redirection mechanism is closed. This allows for the centralized collection of defective products without manual supervision, reducing labor costs.
[0019] As a preferred embodiment of this utility model, the redirection mechanism is a baffle structure, and the angle formed between the baffle structure and the conveying direction of the first main transmission channel is adjustable.
[0020] Different products have different production and conveying speeds. To ensure accurate and stable replacement of the conveying channel, the tilt angle of the baffle can be adjusted according to the actual speed.
[0021] In a preferred embodiment of this invention, the reversing mechanism is connected to an automated control system, which monitors and adjusts the opening and closing of the reversing mechanism and its angle adjustment in real time. Simultaneously, the automated control system is electrically connected to the sensing device. When the automated control system receives an alarm signal from the sensing device, it activates the reversing mechanism.
[0022] As a preferred embodiment of this utility model, a dairy product packaging cup receiving pool is provided at the other end of the lateral transmission channel away from the first main transmission channel.
[0023] As a preferred embodiment of this invention, second guardrail assemblies are provided on both sides of the lateral transmission channel. The provision of second guardrail assemblies can better protect the safety of the product during transportation.
[0024] As a preferred embodiment of this utility model, the inlet of the capping device is connected to a second main transmission channel, and a second coding device is provided on the second main transmission channel. The second coding device is used to print codes on the cap film on the top of the dairy product packaging cup, and the second main transmission channel is used to transport the dairy product packaging cup to the capping device for capping processing.
[0025] The dairy product packaging cup with a lid is moved on the second main transport channel. When it moves to the position of the second coding machine, a code is printed on the lid of the dairy product packaging cup. After that, the coded dairy product packaging cup is transported to the capping device for capping.
[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0027] This utility model relates to a capping and coding system for dairy product packaging cups. Its structure includes a capping device, a first main conveying channel, and a first coding device located above the channel, all connected in sequence. Furthermore, a sensing device is provided on the side between the capping device and the first coding device. During operation, the dairy product packaging cups move along the first main conveying channel after being discharged from the capping device.

[0038] Example 1
[0039] like Figure 1 and 2 As shown, a lid-printing system for dairy product packaging cups includes the following structure:
[0040] Lid-applying device 1, which is used to cover dairy product packaging cups;
[0041] The first main transmission channel 2 is connected to the outlet of the capping device 1 and is used to receive and transport the capped dairy product packaging cups.
[0042] The first coding device 3 is disposed above the first main transmission channel 2 and is used to print codes on the lid of the dairy product packaging cup.
[0043] The sensing device 4 is disposed on the side of the first main transmission channel 2 between the capping device 1 and the first coding device 3; the sensing device 4 is used to sense whether there is a cap on the top of the dairy product packaging cup, and the sensing device 4 is connected to an alarm unit.
[0044] During operation, dairy product packaging cups are discharged from the capping device and move along the first main conveyor channel. When passing the sensing device, if the cup is detected as uncapped, the sensor will sound an alarm, prompting the worker to handle the situation. Capped cups continue to the first coding machine for cap coding. This system allows for effective identification of uncapped products as soon as they reach the cap coding machine, enabling timely responses, reducing defective product rates, controlling costs, and facilitating widespread adoption.
[0045] In some embodiments, the sensing device 4 includes an infrared sensor, an ultrasonic sensor, or a laser sensor.
[0046] In some embodiments, the height of the sensing device 4 is adjustable. The adjustable height of the sensing device can accommodate products of different heights. The height of the sensing device is within the height range of the lid of the covered dairy product packaging cup. When the covered dairy product packaging cup passes the sensing device, the signal emitted by the sensing device encounters the lid and responds, indicating the presence of a lid. When an uncovered dairy product packaging cup passes the sensing device, the signal emitted by the sensing device does not encounter the lid and does not receive a response, indicating the absence of a lid, and the sensing device issues an alarm.
[0047] The sensor's height is adjustable to accommodate lids of products of different heights, ensuring accurate detection of whether cups of various sizes are covered.
[0048] In some embodiments, a first guardrail assembly 21 is provided on the side of the first main transmission channel 2. The provision of the first guardrail assembly can better protect the safety of the product during transportation.
[0049] In some embodiments, such as Figure 3 As shown, a lateral transmission channel 22 is connected to the side of the first main transmission channel 2 between the sensing device 4 and the first coding device 3.
[0050] A redirection mechanism 221 is provided at one end of the lateral transmission channel 22 near the first main transmission channel 2. The redirection mechanism 221 is used to redirect the dairy product packaging cups on the first main transmission channel 2 to the lateral transmission channel 22.
[0051] In use, whenever the sensor detects an uncapped dairy product cup passing by, the redirection mechanism is activated, diverting the dairy product cups on the first main transport channel to the lateral transport channel, and then the redirection mechanism is deactivated. This allows for the centralized collection of defective products without manual supervision, reducing labor costs.
[0052] In some embodiments, the redirection mechanism 221 is a baffle structure, and the angle formed between the baffle structure and the conveying direction of the first main conveying channel 2 is adjustable. Different products have different production conveying speeds; to ensure accurate and stable switching of the conveying channel for the packaged goods, the tilt angle of the baffle can be adaptively adjusted according to the actual speed.
[0053] In some embodiments, the reversing mechanism 221 is connected to an automated control system, which monitors and adjusts the opening and closing of the reversing mechanism 221 and its angle adjustment in real time; simultaneously, the automated control system is electrically connected to the sensing device 4. When the automated control system receives an alarm signal from the sensing device, it activates the reversing mechanism.
[0054] The automated control system receives alarm signals from the sensing device 4 via an electrical connection and controls the starting and stopping of the redirection mechanism 221 accordingly to automatically separate defective products.
[0055] In some embodiments, a dairy product packaging cup receiving pool 222 is provided at the other end of the lateral transmission channel 22 away from the first main transmission channel 2.
[0056] In some embodiments, second guardrail assemblies are provided on both sides of the lateral transmission channel 22. The provision of second guardrail assemblies can better protect the safety of the product during transportation.
[0057] In some embodiments, the inlet of the capping device 1 is connected to a second main transmission channel 5, and a second coding device 6 is provided on the second main transmission channel 5. The second coding device 6 is used to print codes on the cap film on the top of the dairy product packaging cup, and the second main transmission channel 5 is used to transport the dairy product packaging cup to the capping device 1 for capping processing.
[0058] The dairy product packaging cup with a lid is moved on the second main transport channel. When it moves to the position of the second coding machine, a code is printed on the lid of the dairy product packaging cup. After that, the coded dairy product packaging cup is transported to the capping device for capping.
[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
