Description

Technical Field

[0001] This utility model belongs to the technical field of automated bottle transportation equipment, specifically relating to an automatic feeding mechanism for FOB bottles. Background Technology

[0002] In the packaging industry, FOB bottles specifically refer to plastic bottles that use a "press-screw-open" mechanism. The core characteristic of FOB bottles is that to open them, you must press down on the cap to release the internal safety latch before you can rotate it open. This design aims to prevent children from easily opening the bottle and accidentally ingesting the liquid. Compared to ordinary screw-top bottles, FOB bottles have more complex latches, grooves, and spring structures inside the cap and neck, requiring higher mold costs and manufacturing precision. After filling and capping, FOB bottles are typically disordered and inconsistently oriented when they exit the filling line's discharge track. To organize them into a neat arrangement and package them, a bottle-sorting-rowing-packaging process is generally used. Existing automated equipment usually uses vibratory feeders to sort and orient the disordered bottles. However, vibratory feeders have poor adaptability to changes in bottle shape; the internal tracks and orienting devices of the vibratory feeder are custom-designed for specific bottle shapes. Once you change to bottles of different shapes and sizes, you must replace or significantly adjust the vibratory feeder's liner and tracks. This work is very time-consuming and requires specialized technicians, leading to extended changeover times on the production line and impacting production efficiency. Furthermore, within the vibratory feeder, bottles constantly rub and collide with each other and with the tracks. While plastic bottles are relatively sturdy, there is still a risk of scratching the bottle or abrading the labels, especially for high-end cosmetic bottles or bottles with elaborate printing and labels. The vibratory feeder also generates continuous and significant noise during operation, which is detrimental to the workshop environment. Utility Model Content

[0003] To address the aforementioned problems and technical needs, this utility model provides an automatic feeding mechanism for FOB bottles. This mechanism can automatically sort and position filled FOB bottles and use pneumatic blowing to transport them. It can quickly change shapes, adapt to multi-variety production, avoid damage to the bottle body, reduce noise, and form a well-paced processing line.

[0004] The technical solution of this utility model is as follows: An automatic feeding mechanism for FOB bottles includes a filling machine, a positioning and sorting mechanism, a compressor, a feeding pipe, an inclined feeding platform, and a discharging assembly. The end of the filling machine is connected to the positioning and sorting mechanism. Bottles output from the filling machine sequentially enter the positioning and sorting mechanism. The positioning and sorting mechanism is located on the top surface of the compressor housing. A row of bottle grooves is provided inside the positioning and sorting mechanism, and multiple bottles are neatly arranged within these grooves. The overall positioning mechanism clamps and positions the bottles from both sides. The bottom of the positioning and sorting mechanism is connected to... Multiple feeding pipes correspond one-to-one with the bottle body grooves, and the compressor inputs compressed air into the feeding pipes; the inclined discharge platform is built on a fixed support opposite the compressor housing, and a discharge assembly is installed on the inclined discharge platform. Multiple feeding pipes pass out from the bottom of the compressor housing, and the other end of the feeding pipes is connected to the top of the discharge assembly. The bottles in the feeding pipes are blown into the discharge assembly, and the discharge assembly can drive the bottles to slide on the inclined discharge platform, position the bottles to the discharge position, and then release the bottles. The bottles are arranged in an array at the bottom of the inclined discharge platform.

[0005] Furthermore, the positioning and sorting mechanism includes a positioning bracket, a first clamping assembly, and a second clamping assembly. The positioning bracket is suspended and one end is connected to the end of the filling machine. The positioning bracket has a channel in the middle to accommodate the bottle, and opposing positioning plates on both sides of the channel. The bottle's recess is located inside one of the positioning plates. Correspondingly, the two positioning plates have perforated push-material windows, which are aligned with the bottle's arrangement. The positioning bracket has a first clamping assembly and a second clamping assembly on its two sides. The first clamping assembly includes a first bracket, a first cylinder, and a first push-material plate. The first cylinder is fixedly mounted on the top of the first bracket, and the front end of the first cylinder...

The second clamping assembly includes a second bracket, a second cylinder, a second pusher plate, and a telescopic bottom plate. The second cylinder is fixedly installed on the top of the second bracket, and the front end of the second cylinder is connected to the second pusher plate. The second pusher plate is pushed into the channel through a pusher window on the other side. A third cylinder is also connected to the side of the second bracket, and the front end of the third cylinder is connected to the telescopic bottom plate. The bottom of the channel of the positioning bracket is hollowed out. The third cylinder drives the telescopic bottom plate to move telescopically at the bottom of the channel, so that the telescopic bottom plate opens or closes the bottom surface of the channel. All bottles entering the channel are supported by the telescopic bottom plate.

[0006] Furthermore, a telescopic baffle is provided at one end of the positioning bracket connected to the filling machine. When the telescopic baffle extends, it can close the channel entry end and block the bottle body to the outside. A buffer spring is provided at the connection between the first cylinder and the first pusher plate, and a buffer spring is also provided at the connection between the second cylinder and the second pusher plate.

[0007] Furthermore, a receiving end is provided directly below the channel, and a through hole is provided inside the receiving end for the bottle to pass through. The feeding pipe is connected to the bottom of the receiving end. After the bottle falls, it enters the feeding pipe through the through hole. Air source interfaces are also provided on both sides of the receiving end. The air source interfaces are connected to the compressor. The compressor inputs compressed air into the feeding pipe through the air source interfaces, driving the bottle to move in the feeding pipe.

[0008] Furthermore, the feeding assembly includes support rods, sliding rods, cylinders, and a feeder. Support rods are fixedly installed on both sides of the inclined feeding platform, with the support rods perpendicular to the inclined feeding platform. The top of each support rod is provided with a fixing block and a cylinder, and a sliding rod is connected to the top of each support rod. The sliding rods are parallel to the inclined feeding platform. One sliding rod is connected to the cylinder, and the other sliding rod passes through the fixing block. The upper ends of the two sliding rods are fixedly connected by a crossbar, and the lower ends of the two sliding rods are connected to the feeder. The cylinder drives the sliding rods to reciprocate along the inclined surface, and the sliding rods drive the feeder at the bottom to slide up and down on the inclined feeding platform.

[0009] Furthermore, a return spring is provided on the slide rod on the fixed block, and a retaining ring is fixedly connected to the slide rod. The return spring is located on the outside of the slide rod, with one end connected to the retaining ring and the other end connected to the side of the fixed block.

[0010] Furthermore, a clamp is provided on the outside of the slide rod connecting the cylinder, which can clamp or release the slide rod.

[0011] Furthermore, the feeder includes a support, a discharge conduit, a hopper, and a door panel. The support is fixedly connected to slide rods on both sides. The hopper is located at the bottom of the support and is divided into multiple compartments. Each compartment contains one bottle. Each compartment is equipped with a discharge conduit at the top. The outlet end of the feed pipe is sealed to the discharge conduit. Bottles blown out from the feed pipe fall into the compartments in the hopper through the discharge conduit. The back of the hopper is equipped with a door panel that can be opened and closed freely. Opening the door panel releases the bottles in the hopper.

[0012] Furthermore, the bracket is equipped with a vertical cylinder at the top, and a door panel is connected to the bottom of the vertical cylinder. Slots are provided on both sides of the door panel. The vertical cylinder drives the door panel to move up and down along the slots to open or close the back of the hopper.

[0013] The beneficial effects of this utility model are: 1) Compared with traditional vibratory feeder feeding, this mechanism has great flexibility and fast ring function, which is suitable for small batch and multi-variety production lines. When changing the type, it is only necessary to adjust the size of the bottle groove and channel in the positioning bracket, as well as adjust the blowing time and blowing force, so as to adapt to bottles of different sizes and weights. It has better applicability and simpler maintenance. 2) The non-contact air-blowing conveying mode of pipeline feeding can make the bottle and pipeline almost frictionless, which can perfectly protect the appearance of the bottle, avoid friction caused by high frequency vibration, avoid scratches and wear on the bottle body, and reduce physical damage to the surface of the bottle product. 3) The mechanical structure of this device is simple, with low maintenance threshold and cost. Moreover, the noise only comes from the instantaneous exhaust sound of the compressor and solenoid valve, resulting in a low overall noise level. This can significantly improve the working environment and enable continuous operation. It is suitable for designing a continuous production line with a clear rhythm, which can accelerate the process of bottle assembly and packaging. Attached Figure Description

The telescopic baffle 451 retracts, and the third cylinder 45 extends the telescopic bottom support plate 44 forward. The telescopic bottom support plate 44 is positioned directly below the channel 22. Bottles enter the channel 22 one after another.

Bottle 11 enters the feeding pipe 6 through the receiving end 51. Compressor 5 blows compressed air into the feeding pipe 6 through the air source interface 52. The compressed air drives bottle 11 to slide forward in the feeding pipe 6. Bottle 11 slides to the other end of the feeding pipe 6 and enters the discharge pipe 82 from the feeding pipe 6, and then enters the hopper 83 from the discharge pipe 82. One bottle 11 falls into each compartment of the hopper 83. Cylinder 73 drives slide rod 72 to slide backward on the inclined discharge platform 9. Both slide rods 72 simultaneously drive the feeder 8 to slide backward, so that the feeder 8 approaches the discharge height and clamps when it reaches the discharge position. The clamp 75 clamps the slide bar 72, keeping the feeder 8 fixed. The vertical cylinder 85 pulls the door plate 84 upward, and the door plate 84 slides along the slot, opening the hopper 83. The bottles 11 in the hopper 83 slide out of the hopper 83 simultaneously and are stacked in an array at the bottom of the inclined drop platform 9, completing the feeding. Then the vertical cylinder 85 resets, the door plate 84 closes, the clamp 75 releases the slide bar 72, and the slide bar 72 resets under the action of the reset spring 722, waiting for the next feeding. When the array of bottles stacked at the bottom of the inclined drop platform 9 reaches the preset size, the downstream equipment removes them as a whole or pushes them into the packaging machine for packaging and feeding.
