Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic bottle assembly equipment, in particular to a bottle cap feeding machine. Background Art

[0002] The mouth of a cosmetic bottle is generally covered with a bottle cap, for example, a cosmetic bottle for nail polish has a semi-conical shape with a hollow interior, that is, the outer diameter of the bottle cap gradually increases from the upper end to the lower end, and the upper end of the bottle cap is closed, and the lower end is open; on the automatic assembly line of cosmetic bottles, it is required that the closed end of the bottle cap is all facing in one direction and loaded one by one in sequence. If a vibration plate is still used for loading, although the bottle caps can be arranged neatly in sequence, it is difficult to make the closed end of the bottle cap all face in one direction. Some small and medium-sized enterprises still use manual sorting to send the bottle caps to the production line in sequence. This method obviously leads to higher labor costs and is prone to low production efficiency due to human factors. In this context, the applicant is committed to developing a bottle cap loader to realize automatic loading instead of manual sorting, further reduce labor costs and improve production efficiency. Summary of the invention

[0003] The utility model aims to realize automatic feeding instead of manual sorting, further reduce labor costs and improve production efficiency.

Several groups of fixed ladder blocks are arranged in an equidistant array, and the upper ends gradually increase in height. Several groups of movable ladder blocks are arranged in an equidistant array, and the upper ends gradually increase in height. Several groups of fixed ladder blocks and several groups of movable ladder blocks are cross-arranged with each other. A first inclined surface is provided at the upper end of the fixed ladder block, and a second inclined surface is provided at the upper end of the movable ladder block. The lifting cylinder drives the movable ladder block to move up and down.

[0009] Furthermore, the lifting mechanism also includes a baffle plate for preventing bottle caps from standing, and the baffle plate for preventing bottle caps from standing is fixedly arranged above the conveying mechanism.

[0010] Furthermore, the forward and reverse detection mechanism includes a first optical fiber sensor and a second optical fiber sensor, both of which are electrically connected to the controller, the sensing end of the first optical fiber sensor faces the transmission direction of the transmission mechanism, and the second optical fiber sensor is located on the side of the transmission mechanism.

[0011] Furthermore, the forward and reverse detection mechanism also includes a stopper, the stopper is fixedly arranged at one end of the transmission mechanism, and the first optical fiber sensor is fixedly arranged on the stopper.

The rotating cylinder drives the Z-axis driving cylinder to rotate, and the Z-axis driving cylinder drives the finger cylinder to move back and forth. The finger cylinder is located above the conveying mechanism.

[0014] The beneficial effects of the utility model are as follows: when it is necessary to load bottle caps, people directly pour the bottle caps into the hopper, lift the bottle caps in the hopper onto the conveying mechanism through the lifting mechanism, the conveying mechanism conveys the bottle caps to the front and back detection mechanism, the front and back detection mechanism performs front and back detection on the bottle caps on the conveying mechanism, the detected reverse bottle caps are blown into the hopper through the air blowing rejection mechanism, the detected forward bottle caps are clamped by the clamping claw mechanism and unloaded to the production line for the next operation, so that the utility model realizes automatic loading.

[0028] The utility model is further described below with reference to the accompanying drawings.

[0029] like Figures 1 to 6 The bottle cap loading machine shown includes: a controller, a hopper 1, a conveying mechanism 2, a lifting mechanism 3 for lifting the bottle caps in the hopper 1 onto the conveying mechanism 2, a front and back detection mechanism 4 for performing front and back detection on the bottle caps on the conveying mechanism 2, an air blowing and rejecting mechanism 5 for blowing the reverse bottle caps on the conveying mechanism 2 off into the hopper 1, and a clamping mechanism 6 for unloading the forward bottle caps on the conveying mechanism 2.

[0030] The controller controls the conveying mechanism 2, the lifting mechanism 3, the positive and negative detection mechanism 4, the air blowing and rejecting mechanism 5, and the clamping mechanism 6 to work respectively.

[0031] The hopper 1 and the air blowing and rejecting mechanism 5 are respectively located on both sides of the conveying mechanism 2, the lifting mechanism 3 cooperates with the conveying mechanism 2, the front and back detection mechanism 4 is fixedly arranged at the unloading end of the conveying mechanism 2, and the clamping mechanism 6 and the air blowing and rejecting mechanism 5 cooperate with the front and back detection mechanism 4 respectively.

[0032] The transmission mechanism 2 includes a driving motor 21 , a pivot wheel 22 and two sets of round belts 23 . The two sets of round belts 23 are pivotally connected to the pivot wheel 22 in parallel. The driving motor 21 drives the pivot wheel 22 to rotate.

[0033] The lifting mechanism 3 includes several groups of fixed ladder blocks 31, several groups of movable ladder blocks 32, a lifting cylinder 33, and a bottle cap standing baffle 34. The fixed ladder blocks 31 and the movable ladder blocks 32 are both located in the hopper 1. Several groups of fixed ladder blocks 31 are arranged in an equidistant array, and the upper ends are gradually increased. Several groups of movable ladder blocks 32 are arranged in an equidistant array, and the upper ends are gradually increased. Several groups of fixed ladder blocks 31 and several groups of movable ladder blocks 32 are arranged crosswise with each other. The upper end of the fixed ladder block 31 is provided with a first inclined surface 310, and the upper end of the movable ladder block 32 is provided with a second inclined surface 320. The lifting cylinder 33 drives the movable ladder block 32 to move up and down.

[0034] The lifting cylinder 33 drives the movable ladder block 32 to move upward, lifts up some of the bottle caps in the hopper 1, and after the bottle caps roll along the second inclined surface 320 to the upper end of the next fixed ladder block 31, the lifting cylinder 33 drives the movable ladder block 32 to move up and down, and the bottle caps on the upper end of the fixed ladder block 31 continue to roll along the first inclined surface 310 to the next movable ladder block 32, and so on and so forth until the bottle caps are delivered between the two groups of round belts 23 of the conveying mechanism 2.

[0035] The two sets of circular belts 23 have the function of center positioning for the bottle caps. When the bottle caps are located between the two sets of circular belts 23 and move, they are not easily stuck and more grasping space is provided for the subsequent grasping of the clamping mechanism 6. The design of the two sets of circular belts 23 can also be compatible with the transportation of more types of bottle caps, and the center of the bottle cap can be more accurately located at the center of the first optical fiber sensor 41 to prevent misjudgment.

[0036] The anti-bottle cap standing baffle 34 is fixedly arranged above the conveying mechanism 2, and the distance between the anti-bottle cap standing baffle 34 and the two groups of round belts 23 is greater than the thickness of the bottle caps but less than the height of the bottle caps, so that the standing bottle caps can be prevented from being sent between the two groups of round belts 23. That is to say, when the standing bottle caps are about to be sent to the conveying mechanism 2, they will be blocked by the anti-bottle cap standing baffle 34 and will be blocked and fall back into the hopper 1.

[0037] The forward and reverse detection mechanism 4 includes a first optical fiber sensor 41, a second optical fiber sensor 42, and a block 43. The first optical fiber sensor 41 and the second optical fiber sensor 42 are both electrically connected to the controller. The sensing end of the first optical fiber sensor 41 faces the transmission direction of the transmission mechanism 2, and the second optical fiber sensor 42 is located on the side of the transmission mechanism 2. The block 43 is fixedly set at one end of the transmission mechanism 2, and the first optical fiber sensor 41 is fixedly set on the block 43.

[0038] The driving motor 21 drives the pivot wheel 22 to rotate, thereby driving the circular belt 23 to transfer the bottle cap to the block 43. After the second optical fiber sensor 42 senses the bottle cap, it gives a signal to the controller. The controller controls the first optical fiber sensor 41 to start working. If the first optical fiber sensor 41 senses the bottle cap at this time, it means that the direction of the bottle cap is forward, that is, the closed end of the bottle cap is facing the sensing end of the first optical fiber sensor 41. At this time, the controller controls the clamping mechanism 6 to clamp the forward bottle cap and unload it to the production line for the next operation; if the first optical fiber sensor 41 does not sense the bottle cap at this time, it means that the direction of the bottle cap is reverse, that is, the open end of the bottle cap is facing the sensing end of the first optical fiber sensor 41. At this time, the controller controls the air blowing and rejection mechanism 5 to work, and blow the reverse bottle cap into the hopper 1.

[0039] The air blowing and rejecting mechanism 5 includes a solenoid valve and an air blowing head. The solenoid valve is communicated with the air blowing head, and the solenoid valve is electrically connected to the controller. The air blowing head is located on the side of the conveying mechanism 2.

[0040] When in use, the solenoid valve is connected to an external blower. When the controller controls the solenoid valve to open, the air inside the blower is blown out through the blowing head to blow the reverse bottle caps on the conveying mechanism 2 into the hopper 1.

[0041] The gripper mechanism 6 includes a rotating cylinder 61 , a Z-axis driving cylinder 62 , and a finger cylinder 63 . The rotating cylinder 61 drives the Z-axis driving cylinder 62 to rotate, and the Z-axis driving cylinder 62 drives the finger cylinder 63 to move back and forth. The finger cylinder 63 is located above the conveying mechanism 2 .

[0042] After the finger cylinder 63 grabs the forward bottle cap on the conveying mechanism 2, under the dual-axis linkage of the rotating cylinder 61 and the Z-axis driving cylinder 62, the finger cylinder 63 cooperates to unload the forward bottle cap to the production line.

[0043] The working principle of the utility model is as follows: when bottle caps need to be loaded, people directly pour the bottle caps into the upper hopper 1, and the lifting cylinder 33 drives the movable ladder block 32 to move upward to lift up some of the bottle caps in the hopper 1, and the bottle caps at the upper end of the movable ladder block 32 roll along the second inclined surface 320 to the upper end of the next fixed ladder block 31, and then the lifting cylinder 33 drives the movable ladder block 32 to move up and down, and the bottle caps at the upper end of the fixed ladder block 31 continue to roll along the first inclined surface 310 to the next movable ladder block 32, and so on and so forth until the bottle caps are delivered between the two sets of round belts 23 of the conveying mechanism 2.

[0044] The driving motor 21 drives the pivot wheel 22 to rotate, thereby driving the round belt 23 to convey the bottle cap to the stopper 43. After the second optical fiber sensor 42 senses the bottle cap, it sends a signal to the controller, and the controller controls the first optical fiber sensor 41 to start working. If the first optical fiber sensor 41 senses the bottle cap at this time, it means that the direction of the bottle cap is positive, that is, the closed end of the bottle cap is facing the sensing end direction of the first optical fiber sensor 41. At this time, the controller controls the finger cylinder 63 to grab the positive bottle cap on the conveying mechanism 2, and then under the dual-axis linkage of the rotating cylinder 61 and the Z-axis driving cylinder 62, the finger cylinder 63 is cooperated to unload the positive bottle cap to the production line;

[0045] If the first optical fiber sensor 41 does not sense the bottle cap at this time, it means that the direction of the bottle cap is reverse, that is, the open end of the bottle cap is facing the sensing end of the first optical fiber sensor 41. At this time, the controller controls the solenoid valve to open, and the air inside the blower is blown out through the blowing head to blow the reverse bottle cap on the conveying mechanism 2 into the hopper 1.

Therefore, equivalent changes made within the scope of the patent application of the present invention still fall within the scope covered by the present invention.
