Description

Technical Field

[0001] The invention relates to the technical field of packaging machinery, and in particular to a bottle cap unscrambling machine. Background Art

[0002] The bottle caps of beer and beverage bottles are usually round, including metal caps, plastic caps, and crown caps. The specification characteristics are usually that the height of the bottle cap h is less than the diameter of the bottle cap d. In the production and processing of bottle caps or the beer and beverage filling industry, in order to achieve large-scale automated production, the output speed and stability of the bottle cap material flow are required to be high. Usually, a bottle cap sorting machine is used to sort the disordered round bottle caps into a posture with the cap openings facing the same direction and output them in sequence, so as to meet the working requirements of subsequent production or filling equipment. Existing bottle cap sorting equipment usually uses mechanisms such as vibration plates and posture adjustment slides. By driving the bottle caps to move one by one along the posture adjustment slide and gradually adjusting the posture, the orientation of the bottle caps is adjusted to be consistent.

[0003] However, the existing bottle cap sorting equipment has a relatively complex structure, and the posture adjustment slide must be strictly matched with the bottle caps of corresponding specifications. It is not compatible with bottle caps of various specifications. When replacing the bottle caps, the corresponding sorting mechanism must be replaced, and the equipment utilization rate is low. Summary of the invention

By using this equipment, circular bottle caps with a height dimension h smaller than a diameter dimension d can be quickly and efficiently sorted from a disordered state to an arrangement with the cap openings facing the same direction and output in sequence. It only needs to adjust the settings of individual components of the equipment to adapt to bottle caps of different specifications, and the applicability is greatly improved.

[0006] The specific structures of the components of the present invention are described as follows: The spindle assembly is fixed to the upper part of the top plate of the frame assembly through its internal bearing seat; the motor assembly is installed and fixed to the lower interior of the frame assembly, and drives the spindle to rotate through gears or belts, chains, friction wheels or other transmission methods, thereby driving all parts fixed on the spindle to rotate together.

[0007] The turntable is connected and fixed together with the main shaft; the positioning plate is fixed to the outside of the lower plate of the turntable, and a number of positioning grooves of inverted "U"-shaped structure are evenly arranged on the circumference of the positioning plate; on the lower plate of the turntable, with the center of the plate as the center of the circle, a number of linear bearings and core shaft assemblies are evenly arranged, and the linear bearings are fixed on the lower plate of the turntable, and a core shaft assembly is arranged inside each linear bearing; when the main shaft drives the turntable to rotate, under the joint action of the cylindrical cam and the positioning plate, all the core shaft assemblies can slide up and down in the linear bearings while orbiting around the axis of the main shaft.

[0008] The rotating disk is fixedly connected to the turntable as a whole; the hopper assembly is supported on the upper end of the main shaft by a lower bearing and is fixedly connected to the frame assembly through a side connecting plate.

[0009] Furthermore, the core shaft assembly includes a mounting seat, on which an outer bearing, an inner bearing and a core shaft are fixedly mounted, and the positioning block is fixed to the top of the core shaft by screws; the inner bearing cooperates with the cam groove on the outer circumferential surface of the cylindrical cam, and when the turntable rotates, the inner bearing slides up and down in the linear bearing under the action of the cam groove of the cylindrical cam; the outer bearing cooperates with the inverted "U"-shaped structural positioning groove at the circumferential position of the positioning plate, and the outer bearing slides up and down in the positioning groove, thereby preventing the core shaft assembly from rotating around the axis centerline of the core shaft while sliding up and down.

[0010] Furthermore, the bottle cap unscrambling machine is provided with a compressed air blowing device at the cap feeding point, and the air outlet of the compressed air blowing device is aligned with the semicircular slot position of the dial.

[0011] Furthermore, the front cap outlet channel and the rear cap outlet channel are both provided with inner and outer fork plates for guiding the bottle caps out.

[0012] Furthermore, the bottom surface of the front cover outlet channel is flush with the upper surface of the dial, the bottom surface of the rear cover outlet channel is flush with the upper surface of the turntable, the bottom surface of the front cover outlet channel is higher than the bottom surface of the rear cover outlet channel, and the height difference is greater than the height of the bottle cap.

[0013] Furthermore, the guide plate is provided with a height adjustment mechanism, which can adjust the distance between the guide plate and the dial.

[0014] The working principle of the bottle cap unscrambling machine of the present invention is: During operation, the round bottle caps are poured into the hopper assembly, and some of the bottle caps flow into the vibrating screen first. When the vibrating screen vibrates, some of the bottle caps in the vibrating screen fall onto the surface of the rotating disk. Under the centrifugal force generated by the rotation of the rotating disk, all the bottle caps on the surface of the rotating disk flow outward in a circular manner. When the bottle caps pass through the guide plate, the bottle caps with the cap openings facing upward or downward can enter directly under the guide plate and be pushed into the dial. The bottle caps in other postures are blocked by the guide plate and cannot enter directly under the guide plate. As the rotating disk rotates, the bottle caps slide backward in the direction of rotation, and are pushed by new bottle caps to adjust their posture. After sliding for a circle, they are ready to enter under the guide plate again.

[0015] The bottle caps that are diverted and enter under the guide plate are blown to the semicircular slots of the dial by compressed air at the entry point. Since a boss is set between every two semicircular slots, the bottle caps can only enter the slots. A mandrel assembly is set under each semicircular slot. When entering the caps, the mandrel assemblies are in a high position, and the top surface of the positioning block is flush with the upper surface of the dial.

[0016] When the bottle cap with the lid facing upward enters the semicircular slot of the dial, the bottom of the bottle cap contacts the top surface of the positioning block, the bottle cap will not fall, and the bottle cap is in a high position on the surface of the positioning block. When the bottle cap with the lid facing downward falls into the dial slot, due to the gap between the circular positioning block and the semicircular slot of the dial, the bottle cap falls, the cap wall is inserted into the gap, the bottom surface of the bottle cap contacts the top surface of the positioning block, and the bottle cap is in a low position.

[0017] Under the control of the cam groove of the cylindrical cam, the mandrel assembly is in a high position from the cap entry point to the front cap exit point. When the bottle cap moves to the front cap exit point, the inner and outer fork plates provided in the front cap exit channel are used to guide the bottle caps in a high position with the cap opening facing upwards into the front cap exit channel one by one in sequence. From the front cap exit point to the rear cap exit point, the mandrel assembly descends from a high position to a low position, and the bottle cap falls with the positioning block on the top of the mandrel assembly until the cap mouth contacts the upper surface of the turntable and stops falling. When the bottle cap moves to the rear cap exit point, the inner and outer fork plates provided in the rear cap exit channel are used to guide the bottle caps in a low position with the cap opening facing downwards into the rear cap exit channel one by one in sequence.

[0018] When the main shaft rotates counterclockwise, the front cap outlet channel outputs the bottle cap material flow with the cap opening facing upward, and the rear cap outlet channel outputs the bottle cap material flow with the cap opening facing downward. The front and rear cap outlet channels are connected to the bottle cap conveying channels respectively, and one of the conveying channels is used to flip the bottle cap material flow 180°, and then merge with the bottle cap material flow of the other conveying channel. After the merging, the cap material flow faces the same direction and enters the rear process.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. This equipment is suitable for sorting round bottle caps with height h<diameter d. It can be used to sort the caps from a disordered state to the same direction and output them in order. It only needs to adjust the height adjustment structure of the guide plate to adapt to bottle caps of different heights. As long as the height of the bottle cap is h<diameter d, it can be used, and the applicability is greatly improved.

[0020] 2. This equipment has two cap discharging channels. Through clever design, it can output the caps with the cap opening facing upward and downward respectively. Then, it uses the conveying channel to turn one of the cap material flows 180° and merge it with the caps in the other conveying channel to complete the cap sorting work. The whole equipment does not involve the overly complex structure and posture adjustment slideway, and is easy to maintain, with a large processing volume per unit time and high work efficiency.

[0024] The structures of various parts of the present invention are further explained.

[0025] See also Figure 3 The spindle assembly 3 is fixed to the upper part of the top plate of the frame assembly 2 through the bearing seat 31 inside it; the motor assembly 1 is fixed to the lower part of the frame assembly 2, and drives the spindle to rotate through gears or other transmission methods such as belts, chains, friction wheels, etc., thereby driving all the parts fixed on the spindle 32 to rotate together; The turntable 33 is connected and fixed to the main shaft 32; the positioning plate 34 is fixed to the outside of the lower plate of the turntable 33, and a number of positioning grooves of an inverted "U"-shaped structure are evenly arranged on the circumference of the positioning plate 34; on the lower plate of the turntable 33, with the center of the plate as the center of the circle, a number of linear bearings 39 and core shaft assemblies 4 are evenly arranged, and the linear bearings 39 are fixed on the lower plate of the turntable 33, and a core shaft assembly 4 is arranged inside each linear bearing 39; when the main shaft 32 drives the turntable 33 to rotate, under the joint action of the cylindrical cam 30 and the positioning plate 34, all the core shaft assemblies 4 can slide up and down in the linear bearings 39 while orbiting around the axis of the main shaft 32.

[0026] The rotating disk 36 is fixedly connected to the rotating disk 33 as a whole; the hopper assembly 37 is supported on the upper end of the main shaft 32 by the lower bearing, and is fixedly connected to the frame assembly 2 through the side connecting plate.

[0027] See also Figure 4 The spindle assembly 4 includes a mounting seat 40, on which an outer bearing 41, an inner bearing 42 and a spindle 44 are fixedly mounted, and a positioning block 45 is provided and fixed to the top of the spindle 44 by screws; the inner bearing 42 cooperates with the cam groove on the outer circumferential surface of the cylindrical cam 30, and when the turntable 33 rotates, the inner bearing 42 slides up and down in the linear bearing 39 under the action of the cam groove of the cylindrical cam 30; the outer bearing 41 cooperates with the inverted "U"-shaped structure positioning groove at the circumferential position of the positioning plate 34, and the outer bearing 41 slides up and down in the positioning groove, preventing the spindle assembly 4 from rotating around the axis of the spindle 44 while sliding up and down.

[0028] See also Figure 2 , Figure 5 The cap unscrambler is provided with a compressed air blowing device at the cap feeding point A, and the air outlet of the compressed air blowing device is aligned with the semicircular slot position of the dial 35. The front cap outlet channel 6 and the rear cap outlet channel 7 are both provided with inner and outer fork plates for guiding the bottle caps out.

[0029] See also Figure 7-9 The bottom surface of the front cap outlet channel 6 is flush with the upper surface of the dial 35, and the bottom surface of the rear cap outlet channel 7 is flush with the upper surface of the turntable 33. The bottom surface of the front cap outlet channel 6 is higher than the bottom surface of the rear cap outlet channel 7, and the height difference is greater than the height of the bottle cap. The guide plate 5 is provided with a height adjustment mechanism to adjust the distance between the guide plate 5 and the dial 35.

[0030] See also Figure 1-9 , introduce the working principle of the bottle cap unscrambling machine of the present invention: When working, the bottle caps 8 are poured into the hopper assembly 37, and some of the bottle caps first flow into the vibrating screen 38. When the vibrating screen 38 vibrates, some of the bottle caps in the vibrating screen 38 fall onto the surface of the rotating disk 36. As the rotating disk 36 rotates, the cap sorting action is started. When the vibrating screen 38 stops vibrating, the bottle caps in the vibrating screen 38 stop falling, so as to avoid too many bottle caps piling up on the upper surface of the rotating disk 36, thereby affecting the normal cap sorting action.

[0031] Under the action of the centrifugal force generated by the rotation of the turntable 36, all the bottle caps on the surface of the turntable 36 flow toward the outer circumference. When the bottle caps pass through the guide plate 5, the bottle caps with the cap openings vertically upward or vertically downward can enter directly under the guide plate 5 and be pushed into the dial 35, while the bottle caps in other postures are blocked by the guide plate 5 and cannot enter directly under the guide plate 5; as the turntable 36 rotates, the bottle caps slide backward in the rotation direction, are pushed by new bottle caps to adjust their posture, and are ready to enter under the guide plate 5 again after sliding for one circle.

[0032] For further details on the bottle cap diversion principle of the guide plate: see Figure 5 , Figure 6 , the distance between the lower surface of the guide plate 5 and the upper surface of the dial 35 is H, and the distance H is set to be slightly larger than the cap height h (the clearance value Δ is generally 0.2-1.5mm). At this time, only the bottle caps with the cap openings facing upward or downward (i.e. Figure 6 In the two cases (a) and (b) above), the round bottle cap can enter the space between the lower surface of the guide plate 5 and the upper surface of the dial 35. Figure 6 In the two cases (e) and (f), the cap is horizontally facing left or right (limited by the cap diameter d> cap height h, i.e. Figure 6 In the two cases (c) and (d), the bottle caps cannot smoothly enter the space between the lower surface of the guide plate 5 and the upper surface of the dial 35. Then, they are diverted by the guide plate 5 to the surface of the rotary disk 36 during the rotation process. As the rotary disk 36 rotates, the bottle caps slide backward. During the sliding process, they merge with the newly dropped bottle caps, adjust their posture during the rotation process, and after one rotation, they enter the lower part of the guide plate assembly again.

[0033] The bottle caps that are diverted and enter the bottom of the guide plate 5 are blown to the semicircular slots of the dial 35 by compressed air at the entry point A. Since a boss is arranged between every two semicircular slots, the bottle caps can only enter the slots. A spindle assembly 4 is arranged under each semicircular slot. When the caps are entered, the spindle assembly 4 is in a high position, and the top surface of the positioning block 45 is flush with the upper surface of the dial 35.

[0034] When the bottle cap with the lid facing upward enters the semicircular slot of the dial 35, the bottom of the bottle cap contacts the top surface of the positioning block 45, the bottle cap does not fall, and the bottle cap is in a high position on the surface of the positioning block 45. When the bottle cap with the lid facing downward falls into the semicircular slot of the dial 35, due to the gap between the circular positioning block 45 and the periphery of the semicircular slot of the dial 35, the bottle cap falls, the cap wall is inserted into the gap, the bottom surface of the bottle cap contacts the top surface of the positioning block 45, and the bottle cap is in a low position.

[0035] Under the control of the cam groove of the cylindrical cam 30, the spindle assembly 4 is in a high position from the cap entry point A to the front cap exit point B. When the bottle cap moves to the front cap exit point B, the bottle caps in a high position with the cap opening facing upward are introduced into the front cap exit channel 6 in sequence one by one by using the inner and outer fork plates provided in the front cap exit channel 6. From the front cap exit point B to the rear cap exit point C, the spindle assembly 4 descends from a high position to a low position, and the bottle cap falls along with the positioning block 45 at the top of the spindle assembly 4, and stops falling when the bottle cap opening contacts the upper surface of the turntable. When the bottle cap moves to the rear cap exit point C, the bottle caps in a low position with the cap opening facing downward are introduced into the rear cap exit channel 7 in sequence one by one by using the inner and outer fork plates provided in the rear cap exit channel 7.

[0036] When the main shaft 32 rotates counterclockwise, the bottle cap material flow with the cap opening facing upward is outputted from the front cap outlet channel 6, and the bottle cap material flow with the cap opening facing downward is outputted from the rear cap outlet channel 7. The front and rear cap outlet channels are respectively connected to the bottle cap conveying channels, and the posture of the bottle cap material flow is turned 180° by one of the conveying channels, and then merged with the bottle cap material flow of the other conveying channel. After the merging, the cap material flows all face the same direction and enter the rear process.

[0037] At this point, all the cap sorting actions of this equipment are completed, and the bottle caps can enter the subsequent production process. This equipment quickly and efficiently sorts the round bottle caps whose height dimension h is smaller than the diameter dimension d from a disordered state to arrange the caps facing the same direction and output them in order. It has strong applicability, easy maintenance and high efficiency.
