Description

Technical Field

[0001] The present invention relates to the technical field of packaging bottle sorting, and more specifically to a waste gas packaging bottle feeding device and sorting equipment. Background Art

[0002] In the field of waste recycling, the recycling of packaging bottles can generate great economic value. Packaging bottles are generally classified according to their shapes, materials and colors, and then sorted by visual recognition cameras. However, there are many types of recycled packaging bottles, which are gathered together in a messy way, making it difficult to adjust the posture and transport the packaging bottles one by one, which makes it inconvenient for subsequent sorting.

[0003] The inventor attempted to use a rotating conical disk to achieve posture adjustment and directional conveying of packaging bottles. Specifically, a rotating conical disk and a circular disk are provided, a portion of the structure of the conical disk is superimposed on the upper surface of the circular disk, and a loading line along its own tangent direction is provided on the outer periphery of the conical disk, and the width of the loading line only allows a single packaging bottle to be conveyed.

[0004] When in use, the disc rotates to feed the conical disc, and the bottles on the conical disc roll downward along the conical surface until they come into contact with the enclosure assembly of the conical disc. The bottles are driven by the rotating external force of the conical disc during the downward rolling process, so that the axial direction of the bottles in contact with the enclosure is roughly along the tangential direction of the conical disc, and then the bottles with the axial direction along the tangential direction of the conical disc are discharged one by one from the outlet in a directed manner.

[0005] However, in the above technical solution, the method of adjusting the posture of the packaging bottles by rolling downward along the cone surface alone may easily cause a large deviation between the axial direction and the tangential direction of the cone disk of some packaging bottles that are in contact with the enclosure assembly, and as the rotation speed of the cone disk increases, the adjustment effect of the assembly on the position and posture of the packaging bottles becomes worse, which makes it difficult to further increase the feeding speed of the packaging bottles discharged from the outlet of the feeding device, and further makes it difficult to improve the sorting efficiency of the sorting equipment. Summary of the invention

[0006] The purpose of the present invention is to overcome or at least alleviate the deficiencies of the above-mentioned prior art, so as to solve at least one of the above-mentioned technical problems.

[0007] In order to achieve the above-mentioned purpose, the present invention provides a waste gas packaging bottle feeding device, including a workbench, which has a first direction and a second direction which are horizontal and perpendicular to each other, and a conveyor belt and a disc and a cone disc with the same rotation direction are sequentially arranged on the workbench along the first direction, and the conveyor line conveys along the first direction, and the lower surface of the cone disc is in contact with the upper surface of the disc, and the lower surface of the disc is in contact with the upper surface of the end of the conveyor line; the workbench is provided with an enclosure assembly surrounding the conveyor belt, the disc and the cone disc, and the enclosure assembly has an outlet tangential to the cone disc on one side of the cone disc along the second direction; the size of the outlet is set to: allow a single packaging bottle to be output in a manner that the angle between its own central axis and the outlet direction is less than 10 degrees.

[0008] A plurality of air nozzles are evenly distributed on the upper surface of the cone disk around the central axis of the cone disk, and the jet directions of the plurality of air nozzles are inclined downward and parallel to the generatrix direction of the cone disk; the cone disk has a first area, a second area, a third area and a fourth area which are arranged in sequence along the circumferential direction and are respectively fan-shaped, the first area fits the disc, the fourth area is opposite to the opening, the third area and the fourth area have the same fan-shaped angle, the angle α0 of the jet direction between adjacent air nozzles is greater than the fan-shaped angle α1 of the fourth area; and α0 is smaller than the fan-shaped angle α2 of the first area and the fan-shaped angle α3 of the second area; a baffle sleeve is fixed above the cone disk, which can block the gas from the air nozzle toward the first area and the third area, and does not block the airflow from the air nozzle toward the second area and the fourth area.

[0009] The present invention also provides a packaging bottle sorting device, including the above-mentioned waste gas packaging bottle feeding device, and also including a sorting conveyor line, which can receive packaging bottles output one by one from the waste gas packaging bottle feeding device, and the sorting conveyor line has a plurality of visual recognition cameras arranged at intervals along the conveying direction, and a pushing component is provided at each visual recognition camera, and the pushing component is used to push the packaging bottle at the current visual recognition camera away from the sorting conveyor line.

[0010] The beneficial effects of one or more of the above technical solutions are:

[0011] In this solution, a plurality of air nozzles are added when a conveyor belt is used to feed the disc, the disc feeds the conical disc, and the conical disc rotates to adjust the position and posture of the packaging bottle. The air nozzles can only blow toward the second area away from the disc and the third area opposite to the outlet during the rotation of the conical disc. This makes it convenient to use the air nozzles to assist the packaging bottle in falling and adjust the direction of its own axis while avoiding affecting the packaging bottle.

[0012] Specifically, when the retaining sleeve and the air nozzle cooperate: first, the air nozzle will not blow toward the first area where the conical disk and the circular disk meet, thereby avoiding affecting the airflow and affecting the feeding of the circular disk to the conical disk, so that a sufficient amount of packaging bottles can be quickly transported to the upper surface of the conical disk and move toward the outlet along with the upper surface of the conical disk. Secondly, the air nozzle can blow toward the second area, thereby increasing the power of the packaging bottles in the second area to move downward, accelerating the speed of the packaging bottles to move downward, and cooperating with the rotation of the conical disk to provide a torsional force to the packaging bottles, so that the central axis of the packaging bottles in contact with the enclosure assembly is roughly along the tangent direction of the conical disk, so as to facilitate subsequent discharge. Finally, the airflow blows toward the fourth area instead of the third area, which causes the end of the packaging bottle close to the outlet to be subjected to external force, while the end away from the outlet is not subjected to external force, and then the packaging bottle undergoes a small range of torsion, and the head end of the packaging bottle close to the outlet is more closely fitted with the enclosure assembly, reducing the position deviation of the head end of the packaging bottle, so that it can be accurately discharged from the outlet.

[0023] Specifically, the stopper sleeve 108 in this embodiment is installed above the cone disk 1 through a bracket (not shown in the figure), and the stopper sleeve 108 does not rotate with the cone disk 1. The stopper sleeve 108 is fixed to the bracket, and the bracket is fixed to the workbench 10.

[0032] Specifically, the straight baffle includes a first straight baffle 7 and a second straight baffle 8. The first straight baffle 7 is directly formed by the side wall of the workbench 10. The second straight baffle 8 is connected between the first straight baffle 7 and the cone disk 1.

[0033] In the embodiment, an output line is also included, and the width of the conveying line 4 is set to be larger than the width of a single packaging bottle and smaller than the width of two packaging bottles, and the conveying direction of the conveying line 4 is the same as the opening direction of the outlet.

[0034] Specifically, the conveyor line 4 is supported by the mounting frame 2, and an inclined guide plate 3 is provided between the conveyor line 4 and the outlet of the cone disk 1. The inclined guide plate 3 is tangent to the outer periphery of the cone disk 1, and the inner side surface of the conveyor line 4 is also tangent to the outer periphery of the cone disk 1. The inclined guide plate 3 connects the outer periphery of the cone disk 1 and the outer side surface of the conveyor line 4 to form an outlet.

[0035] In addition, there is a fifth area 105 between the end where the outer periphery of the cone disk 1 intersects with the head of the conveyor line 4 and the position where the cone disk 1 and the disk 9 are attached, and the fifth area 105 is between the fourth area 104 and the first area 101. Then, the first area 101, the second area 102, the third area 103, the fourth area 104 and the fifth area 105 are enclosed as a whole to form a cone disk 1 with a whole arc of 2π.

[0036] The present embodiment also provides a packaging bottle sorting device, including the above-mentioned waste gas packaging bottle feeding device, and also including a sorting conveyor line 13, the sorting conveyor line 13 can receive the packaging bottles output one by one from the waste gas packaging bottle feeding device, the sorting conveyor line 13 has a plurality of visual recognition cameras arranged at intervals along the conveying direction, and a pushing component is provided at each visual recognition camera, and the pushing component is used to push the packaging bottle at the current visual recognition camera away from the sorting conveyor line 13.

[0037] Specifically, the sorting conveyor line 13 is supported by a frame 12, and a top frame 14 is provided above the sorting conveyor line 13, and the top frame 14 is used to support structures such as a visual recognition camera and a push component.

[0038] In some specific embodiments, the pushing component includes a cylinder or a high-pressure nozzle, and the pushing direction of the pushing component is perpendicular to the conveying direction of the sorting conveying line 13.

[0039] Working principle: When in use, first place a sufficient amount of various types of packaging bottles on the conveyor belt 6 on the workbench 10 and the loading slide 5. The packaging bottles are transported along the conveyor belt 6 toward the disc 9 along the first direction. Figure 1 For example, the disc 9 rotates clockwise to convey the packaging bottle to the cone 1, and the cone 1 rotates clockwise to convey the packaging bottle to the exit position. During the transportation of the packaging bottle on the cone 1, the packaging bottle rolls downward from the top of the cone surface of the cone 1, and then part of the packaging bottle falls to the inner side surface of the enclosure assembly, and at this time, the center axis of the packaging bottle is roughly parallel to the tangent direction of the outer periphery of the cone 1.

[0040] When the packaging bottles roll downward along the cone disk 1, the packaging bottles in the second area 102 are driven by the downward airflow of the air nozzle 106 along the generatrix direction of the cone disk 1, which can accelerate the driving force for the packaging bottles to roll downward, so that the cone disk 1 can still enable the lowest packaging bottles to move downward until they stop at the enclosure assembly when rotating rapidly.

[0041] When the bottle just moves to the exit position where the inclined guide plate 3 is located, part of the bottle is in the fourth area 104 and the other part is in the third area 103. The part of the bottle in the fourth area 104 is impacted by the airflow, while the part in the third area 103 is not impacted by the airflow. This makes it easy for the part of the bottle in the fourth area 104 to break away from the contact with the upper surface of the cone and be gradually pushed to the exit formed by the inclined guide plate 3, the conveyor line 4 and the outer periphery of the cone 1, so that the bottle can quickly break away from the cone 1 and enter the conveyor line 4.

[0042] It can be seen that when a sufficient number of packaging bottles are intermittently placed on the conveyor line 4 and supplied to the disc 9 and the cone 1, a large number of packaging bottles will accumulate on the upper surface of the cone 1, and some packaging bottles rotating with the cone 1 will be stacked upward along the generatrix direction of the cone 1 without contacting the enclosure assembly. The packaging bottles that move to the exit but do not contact the enclosure assembly and the inclined plate cannot enter the exit, and then these packaging bottles will move to the fifth area 105 with the cone 1, and then move back to the disc 9 from the fifth area 105, waiting to move along the cone 1 again for one circle, until they abut against the enclosure assembly and move from the exit to the conveyor line 4.

[0043] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make various combinations and modifications to the above-mentioned embodiments of the present invention under the guidance of the present invention without departing from the scope of the present invention.
