Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automation packaging, especially a packaging equipment integrating visual counting and buffer conveying functions, which is suitable for intelligent packaging of granular materials such as medicines, foods, and electronic components. BACKGROUND

[0002] In modern industrial production, the packaging demand of various materials is increasing, and the visual particle counting and packaging all-in-one machine, as one of the key equipment for material packaging, is widely used in many fields. However, the existing visual particle counting and packaging all-in-one machine has many shortcomings in actual use.

[0003] Firstly, the feeding height is high, which brings many inconveniences to production operation. The high feeding height increases the labor intensity of manual feeding, increases the labor cost, and to some extent, reduces the production efficiency. At the same time, for some materials or production scenes that have strict restrictions on the feeding height, the high feeding requirement of the existing equipment cannot meet the application demand, limiting its application range.

[0004] Secondly, the existing equipment lacks a buffer bin. This defect limits the packaging speed and efficiency. In the packaging process, the visual particle counting assembly must wait for the packaging assembly to complete the bag making before starting the visual counting, and the counted materials directly enter the bag. This working mode makes the cooperation between the assemblies not smooth enough, and it is difficult to realize efficient continuous production. The bag making process and the particle counting process cannot be carried out synchronously, resulting in waiting time in the whole packaging process, which cannot fully exert the performance of the equipment, and cannot meet the demand of enterprises for high efficiency packaging.

[0005] In addition, the existing visual particle counting and packaging all-in-one machine does not have a cleaning and excess rejection channel. This makes it difficult for the operator to effectively handle the situation of material excess during the packaging process. The unqualified packaging or excess material cannot be cleaned or rejected in time, which not only affects the product quality, but also may cause equipment failure, increases the maintenance cost and downtime of the equipment. At the same time, this also brings many inconveniences to the operator, reduces the controllability and stability of the production process, and is not conducive to the fine management of the production process. INVENTION CONTENTS

[0006] The utility model overcomes the shortcomings of the prior art, provides a visual particle counting and packaging all-in-one machine based on a buffer belt line body, solves the problems of the existing visual particle counting and packaging all-in-one machine in feeding, buffering, and material processing, improves the efficiency, quality, and convenience of material packaging, and meets the demand of modern industrial production.

[0007] In order to solve the above technical problems, the utility model adopts the technical scheme: a kind of vision grain counting packaging integrated machine based on buffer belt line body, including vibration feeding mechanism, vision grain counting mechanism, buffer conveying mechanism and bag making and packaging mechanism connected in sequence, the buffer conveying mechanism includes reversible belt line body, motor driving the line body, the first flap door and the second flap door of first flap door and second flap door located at the both ends of line body can be pneumatically opened and closed.

[0008] Further, the buffer conveying mechanism is integrally formed with the vibration feeding mechanism, or is separately provided, and the buffer conveying mechanism and the vibration feeding mechanism are arranged perpendicular to each other, the receiving and feeding functions of the buffer conveying mechanism are used to reduce the overall height of the vision grain counting packaging integrated machine.

[0009] Further, the buffer conveying mechanism can be integrated with a weighing sensor for real-time detection of the weight of the material on the line body, and when the weight or quantity exceeds a preset threshold, the motor is reversed, and the excess material is discharged into the waste bin through the second flap door. This function can expand the product line with strict weight requirements and assist the grain counting mechanism to accurately package the finished product.

[0010] Further, the first flap door is linked with the signal processor of the vision grain counting mechanism, and is opened when the counting is up, allowing the material to enter the material hopper of the shaper of the bag making and packaging mechanism.

[0011] Further, the surface of the belt line body of the buffer conveying mechanism is provided with a polyurethane anti-slip pattern.

[0012] Further, the vision grain counting mechanism includes a line array camera and a bar-shaped LED backlight source annular infrared light supplementing device.

[0013] Further, a vision grain counting packaging integrated machine based on a buffer belt line body works in the following steps:

[0014] Step S1: the vibration feeding mechanism uniformly delivers the granular material to the scanning area of the vision grain counting mechanism;

[0015] Step S2: the line array camera captures the material image in real time, and completes counting through a vision algorithm;

[0016] Step S3: the material that meets the counting requirement is forwardly conveyed to the bag making and packaging mechanism by the buffer conveying mechanism, and the excess material is discharged in reverse direction by reversing the belt line body.

[0017] Further, in step S3, the forward conveying speed of the buffer conveying mechanism is synchronized with the bag making period of the bag making and packaging mechanism, to realize parallel operation of vision counting and bag making.

[0018] Further, the motor of the buffer conveying mechanism is controlled by an industrial computer program, supports pulse signals, and interacts with the counting result of the vision grain counting mechanism in real time.

[0019] Compared with the prior art, the utility model has the following beneficial effects.

[0020] 1. Breakthrough in space efficiency: the utility model replaces the traditional vertical silo with a horizontal buffer conveying mechanism, reducing the total height of the equipment by 40% (from 2.5 m to 1.8 m), adapting to the height limit of standard factory buildings (≤3 m), and reducing the cost of infrastructure.

[0021] 2. Enhanced fault tolerance: the utility model is designed with reversible belts, allowing excess material to be discharged in reverse within 0.5 seconds, reducing the fault handling time by 80%, reducing downtime losses, and reducing annual maintenance costs by 150,000 yuan (based on single-line production capacity).

[0027] The utility model will be further described below in conjunction with Figure 1 , Figure 2 and Figure 3 , through specific embodiments.

[0028] Example 1: medicine capsule packaging scenario

[0029] Device configuration:

[0030] The vibration feeding mechanism 1 is made of stainless steel, with an adjustable amplitude range of 0.1-3 mm, and is suitable for capsules with a diameter of 3-8 mm;

[0031] The visual particle counting mechanism 3 selects a 2K linear array camera and an 850 mm long LED light source;

[0032] The anti-slip pattern of the buffer conveying mechanism 4 has a depth of 1.0 mm, and the motor speed is adjustable from 0 to 200 rpm;

[0033] The bag-making and packaging mechanism 5 adopts a heat-sealing bag-making machine, and the bag-making cycle is 0.3 seconds / bag.

[0034] Workflow:

[0035] 1. Feeding and counting: the capsules are fed into the visual scanning area by vibration, and the line array camera captures images at a frequency of 10000 times / s.

[0036] 2. Buffering and conveying: the counted capsules (such as 100 capsules per bag) enter the buffer conveying mechanism, and the belt line body is conveyed forward at a speed of 1.5 m / s to the receiving hopper, at which time the bag-making machine synchronously completes the preparation of empty bags;

[0037] 3. Abnormal processing: when the visual particle counting mechanism 3 detects that the line body material exceeds the quantity, the main control board controls the motor to reverse for 1 second, and the excess capsules are discharged into the waste bin through the second flap door, and the system records the fault times and triggers an alarm;

[0038] 4. Packaging and quality inspection: the capsules fall into the pre-made bag, and the heat-sealing mechanism completes the sealing.

[0039] The above excess refers to the quantity that exceeds during the visual particle counting process. The reasons for the excess are: one is that the brake does not stop at the end of the counting stage; two is that the particles fall abnormally during the counting process. The embodiment solves the above problems.

[0040] Example 2: Food nut packaging scenario

[0041] Device improvement:

[0042] The device height is reduced from the traditional multi-stage buffer storage design of 2.5 m to the current integrated buffer material and conveying material of 1.75 m, saving vertical space in the factory building;

[0043] Parallel operation makes the packaging speed increase from 120 bags / min to 200 bags / min, with a capacity increase of 66.7%.

[0044] The depth of the anti-slip pattern is adjusted to 0.8 mm, which is suitable for rough nuts (such as cashews, almonds);

[0045] The visual mechanism adds a polarizing filter to eliminate the reflection of oily surfaces;

[0046] The buffer conveying mechanism is provided with a air cooling device to prevent nuts from seeping oil due to friction heating.

[0047] Effect verification:

[0048] In 8 hours of continuous operation, the device handled 96,000 bags, with only 2 times of fault downtime (due to foreign matter jamming), and the average fault-free time (MTBF) was more than 4000 hours.

[0049] Further, the embodiment can adjust the angle of the belt line body and the vibrating feeding mechanism according to the specific site space, without requiring that the two are perpendicular.

[0050] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model.
