Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, a feeding device for a gasket in a bottle cap comprises a feeding mechanism 1, a material arranging mechanism 2 and a linkage mechanism 3.

In this embodiment, the feeding mechanism 1 includes a hopper 100 and an air duct 101, a material inlet 102 facing the bottom outlet of the hopper 100 is disposed on a wall of the air duct 101, and a chute 103 is connected between the bottom outlet of the hopper 100 and the material inlet 102.

It should be noted that, in the present embodiment, the height from the ground of the bottom outlet of the hopper 100 is greater than the height from the ground of the material inlet 102.

Further, the hopper 100 is fixed on a first bracket (not shown in the drawing), and an openable first transparent end cover 104 is installed at the top inlet of the hopper 100; the air inlet end of the ventilation pipeline 101 is connected with a blower 105; an openable second transparent cover 106 is installed at the upper end of the chute 103, a vibrator 107 is installed at the bottom of the chute 14, a plurality of air outlet holes 108 which are uniformly distributed are respectively arranged on the second transparent cover 106, and the aperture of each air outlet hole 108 is smaller than the outer diameter of the gasket 4.

It should be noted that, by using the first transparent end cap 104 and the second transparent end cap 106, on one hand, a dust-free environment can be maintained to the maximum extent, and external dust is prevented from adhering to the gasket 4; on the other hand can be convenient for the staff from the outside observation to and in time add the material, and in time handle proruption situation such as card material, long-pending material.

In addition, when the air blower 105 is used, air is blown into the air duct 101 from the air inlet end thereof during operation, so that an air flow moving to the material arranging side is formed in the air duct 101.

It should be noted that, by using the vibrator 107, the vibration force generated during the operation is transmitted to the chute 103, so that the gasket 4 leaking from the bottom outlet of the hopper 100 can rapidly enter the air duct 101 through the chute 103 and the material inlet 102.

It should be noted that, the plurality of air outlet holes 108 uniformly distributed on the second transparent cover 106 are used to perform a pressure relief function, so that a normal air pressure condition inside the chute 103 (a relatively closed space is formed inside the chute 103 after the second transparent cover 106 is covered) can be maintained, and normal material sliding can be ensured.

It should be noted that, the aperture of each of the plurality of air outlets 108 is smaller than the outer diameter of the gasket 4, so that the gasket 4 can be blocked while the air flow is normally discharged, and the air flow cannot be discharged from the plurality of air outlets 108.

In this embodiment, the material arranging mechanism 2 includes a cylindrical box 200 with an open upper end, the air outlet end of the air duct 101 leads to the upper port of the cylindrical box 200, a large rotary disc 201 capable of rotating is arranged at the bottom of the cylindrical box 200, a discharge port 202 is arranged at one side of the bottom of the cylindrical box 200, a small rotary disc 203 capable of rotating is arranged at the inner side of the discharge port 202, and a plurality of clamping grooves 204 are respectively arranged around the small rotary disc 203.

Further, the cylindrical box 200 is fixed on a second bracket (not shown in the drawings, the same below), an openable third transparent end cover 205 is installed at the upper port of the cylindrical box 200, and a first motor (not shown in the drawings) for driving the large turntable 201 to rotate is installed on the second bracket; the lower edge of the discharge port 202 is flush with the upper surface of the large turntable 201, a second motor (not shown in the drawing) for driving the small turntable 203 to rotate is mounted on the outer wall of the cylindrical box body 200 above the small turntable 203, the small turntable 203 is close to the large turntable 201 from the upper side and is not in contact with the large turntable 201, and the small turntable 203 and the large turntable 201 rotate in the same direction and both rotate clockwise or anticlockwise; in this embodiment, the small turntable 27 and the large turntable 22 both rotate clockwise.

On one hand, the third transparent end cover 205 can maintain a dust-free environment to the maximum extent and prevent external dust from attaching to the gasket 4; on the other hand, the device can be conveniently observed by workers from the outside and can timely process emergencies such as material blocking, material accumulation and the like.

It should be noted that the lower edge of the discharge port 202 is flush with the upper surface of the large turntable 201, and there is no height difference, which is beneficial to transferring the gasket 4 out through the discharge port 202.

It should be noted that the small turntable 203 is close to the large turntable 201 from above and is not in contact with the large turntable 201, so that the large turntable 201 and the small turntable 203 can operate independently without affecting each other and can be matched with each other; in addition, the small turntable 203 and the large turntable 201 rotate in the same direction, which is beneficial for the small turntable 203 to convey the gasket 4 out through the discharge hole 202 in a 'nearby' manner.

In this embodiment, the linkage mechanism 3 includes a baffle 300, an air cylinder 301, a dial 302, a blocking piece 303, a photoelectric switch 304, an electromagnetic valve 305 and a PLC306, the baffle 300 is rotatably installed in the chute 103 and is arranged along the width direction thereof, a channel 307 for the gasket 4 to pass through is provided between the bottom end of the baffle 300 and the inner bottom surface of the chute 103, the air cylinder 301 drives the baffle 300 to deflect, and the electromagnetic valve 305 is installed in an air supply loop of the air cylinder 301; the shifting sheet 302 is rotatably arranged in the cylindrical box body 200, a gap 308 for the gasket 4 to pass through is formed between the bottom end of the shifting sheet 302 and the upper surface of the large turntable 201, and the blocking sheet 303 deflects synchronously with the shifting sheet 302 on one hand and is matched with the photoelectric switch 304 on the other hand; the PLC306 is electrically connected to the photoelectric switch 304 and the solenoid valve 305, respectively.

In this embodiment, the pick 302 is made of a light material, and has high sensitivity, such as a plastic sheet or a silicone sheet.

Further, a first rotating shaft 109 arranged along the width direction of the chute 103 is rotatably mounted in the chute 103, the upper end of the baffle 300 is fixedly connected to the bottom of the first rotating shaft 109, and the height of the channel 307 is larger than the thickness of one gasket 4; one end of the first rotating shaft 109 extends to the outer side of the chute 103 and is fixedly connected with a rotating arm 110, the air cylinder 301 is rotatably installed on the outer wall of the chute 103, and the end part of a piston rod of the air cylinder 301 is rotatably connected with the lower end of the rotating arm 110.

It should be noted that, with the above structure, the baffle 300 is rotatably installed in the chute 103, and the air cylinder 301 drives the baffle 300 to deflect.

It should be noted that the height of the channel 307 is greater than the thickness of one spacer 4, so that the spacers 4 can pass through the channel 307 in a single flat state, or in a plurality of stacked states, or in a single upright state. When the gasket 4 passes through the channel 307 in a single upright position, it can rapidly pass through the channel 307 in a rolling manner, and when reaching the inlet 102, it will enter the vent duct 101 again in a single flat position through the inlet 102, limited by the height of the inlet 102.

That is, the height of the channel 307 needs to be determined according to the actual use situation, and is not limited herein. The theoretical height of the channel 307 is the internal height of the chute 103 at this point.

Further, a second rotating shaft 206 is rotatably mounted on the inner wall of the cylindrical box body 200, the pick 302 is fixedly connected to one end of the second rotating shaft 206, and the height of the gap 308 is slightly larger than the thickness of one gasket 4; the other end of the second rotating shaft 206 extends to the outside of the cylindrical case 200 and is fixedly connected to a blocking piece 303, and the blocking piece 303 blocks the photoelectric switch 304 from the outside.

It should be noted that, with the above structure, it is realized that the pick 302 is rotatably installed in the cylindrical box 200, and at the same time, the blocking piece 303 and the pick 302 can be synchronously deflected and cooperate with the photoelectric switch 304.

It should be noted that the height of the gap 308 is slightly greater than the thickness of one spacer 4, so that the spacer 4 can be flatly laid around the turntable 201, when the spacer 4 on the turntable 201 is excessive, the spacer 4 will be stacked, if the stacking area is large, in the process of rotating along with the turntable 201, the paddle 302 is pushed, so that the paddle 302 is forced to deflect, the blocking plate 303 is driven to synchronously deflect, the photoelectric switch 304 is further caused to generate a switching signal (level signal), the cylinder 301 is controlled to perform a corresponding action, and the baffle 300 is driven to deflect, thereby controlling the channel 307 to perform an adaptive adjustment.

That is, the gap 308 is used to "limit the height" of the spacer 4, so that the height is determined to be slightly greater than the thickness of one spacer 4, specifically, determined by the actual thickness of the spacer 4.

The invention is further described below with reference to the accompanying drawings:

when the automatic gasket arranging machine works, a large number of gaskets (to-be-printed products) are poured into the hopper 100 by a worker through the top inlet of the hopper 100, the blower 105 and the vibrator 107 work respectively, the gaskets 4 fall through the bottom outlet of the hopper 100, sequentially enter the air duct 101 through the chute 103 and the feeding port 102, and move to the material arranging side along the air duct 101 under the action of air flow; then the gasket 4 falls onto the rotating disc 201 through the upper port of the cylindrical box 200, the large rotating disc 201 and the small rotating disc 203 rotate clockwise, the gasket 4 moves to and is tiled around the large rotating disc 201 under the action of centrifugal force and rotates along with the large rotating disc 201, then the gasket enters the clamping grooves 204 around the small rotating disc 203 one by one, and the gasket is transferred to the conveying mechanism 5 (conveying belt) equipped in the subsequent laser printer one by one through the discharge port 202 under the drive of the small rotating disc 203.

In the above process, when the amount of the gasket 4 on the turntable 201 exceeds, the gasket 4 may be stacked and exceed the gap 308, if the stacked area is large, in the process of rotating along with the turntable 201, the dial 302 is pushed, so that the dial 302 is forced to deflect, the blocking piece 303 is driven by the second rotating shaft 206 to synchronously deflect, the blocking piece 303 no longer shields the photoelectric switch 304 from the outside, so that the photoelectric switch 304 sends a corresponding switch signal (level signal) to the PLC306, the PLC306 sends a control signal to the electromagnetic valve 305, the electromagnetic valve 305 performs a corresponding action, the piston rod of the cylinder 301 is contracted, the blocking piece 300 is driven by the rotating arm 110 and the first rotating shaft 109 to deflect counterclockwise, the height of the channel 307 is reduced, even the channel 307 is cut off, and thus the feeding amount of the feeding mechanism 1 is reduced, even the feeding is suspended.

When the gaskets 4 on the large turntable 201 are restored to the normal amount, the gaskets 4 are not stacked, the poking piece 302 is not pushed, the poking piece 302 naturally resets under the action of gravity, the blocking pieces 303 synchronously reset, the blocking pieces 303 shield the photoelectric switch 304 from the outer side again, so that the photoelectric switch 304 sends corresponding switch signals (level signals) to the PLC306, the PLC306 sends control signals to the electromagnetic valve 305, the electromagnetic valve 305 makes corresponding actions, the piston rod of the air cylinder 301 extends out and resets, the blocking plate 300 is driven by the rotating arm 110 and the first rotating shaft 109 to deflect clockwise and reset, the set height of the channel 307 is restored, and the feeding mechanism 1 restores the original feeding.
