Abstract
Description
Technical Field
[0001] This utility model relates to the field of air bottle processing, and more specifically, to an automatic air bottle feeding device. Background Technology
[0002] In the automated unloading process after injection molding of air bottle / conical bottle bodies, traditional vibratory feeder sorting devices have serious technical defects, such as:
[0003] 1. When the product falls along the vibratory feeder track by its own weight, due to the curvature of the cone surface and the electrostatic adsorption, the large ends of multiple pots interlock, causing material stacking and jamming, requiring manual intervention to clean, resulting in adhesion and obstruction.
[0004] 2. Traditional solutions rely on vibration probability to adjust direction, but the center of gravity of the cone-shaped air bottle is biased towards the larger end, making it prone to random flipping during descent, resulting in loss of product direction control and blockage in the channel;
[0005] 3. Vertical drop feeding causes impact deformation of the spout, and the damage rate of soft materials under the residual temperature of injection molding is ≥5%, which poses a risk of damage. Utility Model Content
[0006] The purpose of this utility model is to provide an automatic air bottle feeding device that can overcome technical problems such as air bottle sticking, random rotation, and damage from drops and impacts during the production process.
[0007] The embodiments of this utility model are implemented as follows:
[0008] An automatic air bottle dispensing device includes:
[0009] The vibration sorting mechanism includes an inclined vibratory plate, the width of the inlet end of the vibratory plate is greater than the width of the outlet end, the width of the outlet end is matched with the length of the cone-shaped air bottle product, and a product detection sensor is provided at the inlet end.
[0010] A directional material conveying mechanism includes at least one material conveying channel, which is composed of a falling section, a buffer section and a horizontal conveying section connected in sequence.
[0011] The pneumatic attitude adjustment mechanism is located in the falling section. It acts on the conical air bottle product through directional airflow and uses the difference in cross-sectional area at both ends of the product to make the product enter the horizontal conveying section with the small end facing forward and the large end facing backward.
[0012] In a preferred embodiment of this utility model, the vibratory plate has a symmetrical trapezoidal structure.
[0013] In a preferred embodiment of the present invention, the falling section is a quasi-vertical channel, the buffer section is an arc-shaped channel of 85-95°, the horizontal conveying section is a trough with an open top, and the channel cross-section of the buffer section gradually changes from the isosceles trapezoid of the falling section to the trough shape of the horizontal conveying section.
[0014] In a preferred embodiment of this utility model, the aforementioned quasi-vertical channel is a nearly vertical channel with a slight inclination angle of 1-3°. The width of the upper base of the isosceles trapezoid is greater than the diameter of the small end of the product and less than the diameter of the large end of the product; the width of the lower base of the isosceles trapezoid is greater than the diameter of the large end of the product.
[0015] In a preferred embodiment of the present invention, a guide rail is provided at the end of the horizontal conveying section.
[0016] In a preferred embodiment of this utility model, the product detection sensor includes a photoelectric sensor or a proximity switch, which is installed above the feed end of the vibratory feeder.
[0017] In a preferred embodiment of the present invention, the above-mentioned pneumatic attitude adjustment mechanism includes a fan and a nozzle connected to the fan. The nozzle's air outlet is horizontal or tilted upward at <5°, and its air outlet direction is directly opposite the smaller end of the middle of the area through which the product's body passes.
[0018] In a preferred embodiment of this utility model, the aforementioned falling section is further provided with an attitude pre-detection sensor, and the pneumatic attitude adjustment mechanism includes two independently controlled airflows: one is a weak airflow that continuously blows the bottom of the falling section; the other is a strong pulse airflow that acts directionally on the product with abnormal attitude, triggered by the attitude pre-detection sensor signal or at a time.
[0019] The beneficial effects of this utility model embodiment are:
[0020] 1. This utility model achieves source screening by redesigning the vibratory feeder structure and combining the width of the guide channel of the vibratory feeder with the physical limitation of the isosceles trapezoidal channel of the falling section, ensuring that only products with the small end facing forward enter the material transfer channel.
[0021] 2. The pneumatic attitude adjustment mechanism utilizes the airflow at the smaller end of the product to generate a differential wind resistance torque, forcibly flipping products with abnormal attitudes, thus greatly improving the success rate of orienting the smaller end forward.
[0022] 3. The feed detection sensor monitors the feeding status and the discharge port posture. The pre-inspection sensor identifies abnormal products in real time and triggers a strong pulse airflow for precise correction, reducing the scrap rate. The pneumatic mechanism and the physical constraints of the channel complement each other, forming a dual protection mechanism to adapt to the flexible production of cone products of different sizes.
[0023] 4. The new feeding device uses a fan to further cool down the material, accelerating the hardening of the soft material under the residual temperature of injection molding and preventing deformation from collision. Attached Figure Description

[0034] First Embodiment
[0035] Please refer to Figure 1-3 This embodiment provides an automatic air bottle feeding device, including a vibration sorting mechanism 1, a directional material conveying mechanism 2, and a pneumatic attitude adjustment mechanism 3.
[0036] The vibration sorting mechanism 1 includes an inclined vibratory plate 11, with the width of the inlet end of the vibratory plate 11 greater than the width of the outlet end. In this embodiment, the vibratory plate 11 has a symmetrical trapezoidal structure. The inlet end of the vibratory plate 11 is a wide-mouth area, and the outlet end is a gradually narrowing guide channel 111. The width of the outlet end matches the length of the conical air bottle 6 product, and guide ribs are provided on the inner wall of the guide channel 111. By constraining the width of the guide channel 111 of the vibratory plate 11 and the guide ribs on the inner wall, combined with the physical limitation of the falling section channel, source screening is achieved to ensure that only products with the smaller end facing forward enter the material transfer channel.
[0037] A product detection sensor 12 is installed at the feed end of the vibratory feeder 11. The data acquired by the product detection sensor 12 is transmitted to the microprocessor 4 of the automatic feeding device. Vibration is only activated when an air bottle 6 is detected entering the vibratory feeder 11, thus improving the energy efficiency of the device. The product detection sensor 12 can be a common photoelectric sensor or a proximity switch, and is installed above the feed end of the vibratory feeder 11.
[0038] The directional material conveying mechanism 2 includes at least one material conveying channel 21, which is composed of a falling section 211, a buffer section 212, and a horizontal conveying section 213 connected in sequence. In this embodiment, a total of four parallel material conveying channels 21 are provided to improve material feeding efficiency.
[0039] Specifically, the falling section 211 is a near-vertical channel, which is a nearly vertical channel with a slight inclination angle of 1-3°. The upper base width of the isosceles trapezoid is greater than the diameter of the small end of the product and less than the diameter of the large end of the product; the lower base width of the isosceles trapezoid is greater than the diameter of the large end of the product.
[0040] The buffer section 212 is an 85-95° arc-shaped channel; in this embodiment, it is a 90° arc-shaped channel. The horizontal conveying section 213 in this embodiment is a square trough with an open top; in other embodiments, it can be V-shaped, U-shaped, or a horizontal slope. The cross-section of the buffer section 212 gradually changes from the isosceles trapezoid of the falling section 211 to the square of the horizontal conveying section 213. The falling section 211 uses a 1-3° inclination angle design, and the buffer section 212 uses a 90° arc-shaped gradient trough design to eliminate the impact of vertical drops and achieve smooth turning.
[0041] The horizontal conveyor section 213 is equipped with a guide rail at its end. The horizontal conveyor section 213 is a square trough with an open top. Its width is greater than the diameter of the product's small end but less than its large end diameter, and the entire horizontal conveyor section 213 has a downward tilt angle of 0.5°-2°. The depth of the square trough in the horizontal conveyor section 213 is greater than half the diameter of the product. The horizontal conveyor section 213 uses a 0.5-2° micro-tilt angle to provide continuous sliding force, combined with the 15-30° downward-sloping flared guide rail at the end, utilizing the product's inertia to accelerate its sliding into the basket, avoiding mechanical impact damage. The guide rail outlet matches the turnover basket's compartment, ensuring that the product falls accurately into the designated position without the need for manual secondary handling.
[0042] The pneumatic attitude adjustment mechanism 3 is located in the falling section 211. It acts on the conical air bottle 6 product through directional airflow and uses the difference in cross-sectional area at both ends of the product to make the product enter the horizontal conveying section 213 with the small end facing forward and the large end facing backward.
[0043] The pneumatic attitude adjustment mechanism 3 includes a fan 31 and a nozzle 32 connected to the fan 31. The outlet of the nozzle 32 is horizontal or tilted upward at <5°, and its air outlet direction is directly facing the smaller end of the product's body passing through the area. It covers the entire bottom surface of the falling section, blows away the accumulated product, and can utilize the effect of airflow at the smaller end of the product to generate differentiated wind resistance torque. This makes the smaller end of the product less affected by the upward airflow of the fan, while the larger end of the product is more affected by the upward airflow of the fan, resulting in the product being arranged with the smaller end in front and the larger end behind.
[0044] Second Embodiment
[0045] Please refer to Figure 1-3 This embodiment provides an automatic feeding device for an air bottle 6, which is largely the same as the automatic feeding device for an air bottle 6 in the first embodiment. The difference is that the falling section 211 of this embodiment is also equipped with an attitude pre-detection sensor 22, and the pneumatic attitude adjustment mechanism 3 includes two independently controlled airflows: one is a weak airflow that continuously blows the bottom of the falling section 211; the other is a strong pulse airflow that acts directionally on products with abnormal attitudes, triggered by the attitude pre-detection sensor 22 signal or timed.
[0046] The attitude pre-detection sensor 22 is connected to the microprocessor 4. When it detects that the air bottle 6 entering the drop section 211 is reversing, it triggers a strong pulse airflow. The attitude pre-detection sensor 22 can use a laser rangefinder to emit a laser beam to measure the distance to the product surface, output contour data in real time, and directly determine the orientation of the large and small ends. Alternatively, it can use photoelectric through-beam sensors symmetrically installed on both sides of the drop section 211 to determine the orientation based on the height difference caused by the smaller end being shorter and the larger end being taller. A camera can also be used in conjunction with an AI algorithm to identify the orientation, or a capacitive proximity switch can be used to determine the product's orientation by detecting changes in capacitance when different ends approach each other. Considering cost, response speed, and accuracy, 2-3 sets of longitudinally arranged photoelectric through-beam sensors are preferred.
[0047] The pneumatic attitude adjustment mechanism 3 uses a centrifugal fan 31, similar to the first embodiment. However, it adds a three-way proportional valve 33, connecting the input airflow and two output airflows. 90% of the output airflow is weak airflow, while 10% is strong airflow on standby. One output airflow, the weak airflow, is a constant branch connected to the wide-mouth flat nozzle 32. The other output airflow connects to the strong pulse solenoid valve 34 and the directional narrow slit nozzle 35. The strong pulse solenoid valve 34 is connected to the microprocessor 4 and opens upon receiving a control signal from the microprocessor 4, focusing the airflow energy onto the 1 / 3 position of the kettle body. The powerful impact causes the air kettle 6 to reverse direction. The directional narrow slit nozzle 35 is positioned above the wide-mouth flat nozzle 32.
[0048] If the budget allows, it can be upgraded to a dual-pressure control fan 31 system, with the low-pressure fan 31 responsible for weak airflow and the high-pressure fan 31 responsible for strong pulses, further improving the response speed, but the cost will increase by about 50%.
[0049] To prevent the air tank 6 from being ejected by the strong pulse airflow, a protective cover 5 is installed on the top of the falling section 211. A through hole for the air tank 6 to enter is provided between the protective cover 5 and the falling section 211.

It should be understood that the embodiments in the specification can be implemented in various alternative forms.
