Description

Technical Field

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

[0002] In the packaging of many products, packaging bottles are used, especially plastic packaging bottles, which are not only beautiful and varied in shape, but also light in weight and low in production cost. They have long been popular in all walks of life.

[0003] The bottle unscrambler sorts the randomly stacked bottles and arranges them in order and direction on the conveyor belt, and transfers the bottles to other machines for the next process (such as filling, labeling, boxing, etc.) at high speed and efficiency to improve the production efficiency of the entire production line.

[0004] The traditional bottle unscrambler cannot correct the bottle mouth in the up and down direction when unscrambling bottles, and the consistency of the bottle mouth direction on the conveyor line is very important. If the bottle mouth direction is inconsistent, it will have a great impact on the subsequent filling and packaging operations. Therefore, in the actual production process, it is necessary to manually regularize the bottles so that the bottle mouth directions of the bottles are completely consistent, which results in a high labor intensity for the workers and certain requirements for the conveying speed of the bottles, resulting in low production efficiency; and for bottles with pull tabs at the bottle mouth (pull tabs are used to open the bottle mouth), in order to facilitate subsequent conveying, labeling and outer packaging operations, it is generally necessary to make the pull tabs on each bottle completely consistent in direction. However, the existing bottle unscrambler cannot rotate and correct the direction of the pull tabs on such bottles when unscrambling bottles, and adjust the pull tabs on the bottles to face a specific direction. Based on this, in order to meet the bottle unscrambling requirements of such bottles, it is necessary to develop a bottle unscrambling and feeding machine that can correct the bottle mouth in the up and down direction and make the pull tabs on the bottles face a specific direction. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a bottle unscrambler, which can automatically convey and sort the packaging bottles with pull tabs at the bottle mouths, so that they are completely consistent in the up and down directions of the bottle mouths and the directions of their pull tabs, so as to facilitate subsequent conveying, labeling and outer packaging operations. The adopted technical solution is as follows:

The bottle feeding trough is arranged downwardly inclined, and the front end opening of the bottle feeding trough is connected with the upper end opening of the corresponding bottle unscrambling and lifting channel; the bottle mouth up and down direction correction mechanism includes at least one lower bottle turning unit, the number of the lower bottle turning units is the same as that of the bottle feeding trough and corresponds to each other, and the lower bottle turning unit is arranged between the corresponding bottle feeding trough and the bottle feeding device, and the lower bottle turning unit is used to receive the packaging bottle of the corresponding bottle feeding trough and automatically correct it in the up and down direction of the bottle mouth to an upright state with the bottle mouth facing upward and the bottle bottom facing downward; the bottle feeding device is used to receive the packaging bottle from each lower bottle turning unit and convey it to the bottle mouth rotation correction mechanism.

[0007] During operation, the packaging bottles to be sorted can be put into the bottle storage container, and the packaging bottles in the bottle storage container are lifted to the front end openings of each bottle inlet slot by each bottle unscrambling and lifting channel of the bottle unscrambling and lifting device. The packaging bottles entering each bottle inlet slot slide backward along the corresponding bottle inlet slot under the action of their own gravity, and then enter the corresponding lower bottle turning unit respectively, and each lower bottle turning unit automatically corrects the packaging bottles in the up and down directions of the bottle mouth to an upright state with the bottle mouth facing upward and the bottle bottom facing downward; the bottle feeding device then receives the packaging bottles from each lower bottle turning unit and conveys them to the bottle mouth rotating correction mechanism; finally, the bottle mouth rotating correction mechanism automatically rotates and corrects each packaging bottle with a pull tab at the bottle mouth, so that the pull tab of each packaging bottle faces a specific direction, which is convenient for subsequent transmission, labeling and outer packaging.

The lower limit position remains unchanged, and the bottom of the bottle of the packaging bottle will gradually swing and tilt downward (the packaging bottle swings downward around the bottle mouth with the limiting plate as the fulcrum, and when the bottle mouth of the packaging bottle is separated from the limiting notch of the bottle mouth, the bottle bottom is at the lower side of the bottle mouth), and then slides down along the lower inner wall of the sorting hopper, thereby automatically correcting the packaging bottle to an upright state with the bottle mouth upward and the bottle bottom downward; if the bottle mouth of the packaging bottle on the bottle supporting movable plate is tilted toward the upper front, the bottle bottom of the packaging bottle cannot pass through the limiting notch of the bottle mouth and is supported by the limiting plate. When the bottle supporting movable plate swings downward around its side part, the packaging bottle slides from the rear end of the plastic bottle sorting groove, and the bottle bottom is at the lower side of the bottle mouth, and then slides down along the lower inner wall of the sorting hopper, thereby automatically correcting the packaging bottle to an upright state with the bottle mouth upward and the bottle bottom downward, and comes out from the lower end of the bottle sorting hopper and falls on the bottle feeding device.

When working, the bottle-feeding translation frame and each front-to-back translation slider can be driven to translate forward or backward along each front-to-back translation guide rail by extending and retracting the piston rod of the front-to-back translation cylinder.

[0028] As a further preferred embodiment of the present invention, the left-right translation mechanism includes at least one left-right translation cylinder and at least one left-right translation guide rail, the left-right translation guide rail is installed on the bottle-feeding translation frame and runs left-right, the left-right translation guide rail is installed with left-right translation sliders that slide with the left-right translation sliders, and each left-right translation slider is connected to the corresponding second translation seat; the cylinder body of the left-right translation cylinder is installed on the bottle-feeding translation frame and runs left-right, and the piston rod of the left-right translation cylinder is connected to the corresponding second translation seat.

During operation, the bottle-feeding translation frame 61 and each front-to-back translation slide block can be driven to translate forward or backward along each front-to-back translation guide rail 622 by extending and retracting the piston rod of the front-to-back translation cylinder 621.

[0067] In this embodiment, the left-right translation mechanism 65 includes a plurality of left-right translation cylinders 651 and a plurality of left-right translation guide rails 652. The left-right translation guide rails 652 are mounted on the bottle-feeding translation frame 61 and extend left-right.

[0068] The following is a brief description of the working principle of this bottle unscrambler:

[0069] In the initial state, the front end of each variable pitch chute 93 is aligned with the rear end of the corresponding bottle inlet trough 41; the first position switching mechanism 96 first switches the position of the first bottle dividing baffle 95, and the rear end of each variable pitch chute 93 is separated from the front end of each bottle unscrambling trough 5111 by the first bottle dividing baffle 95.

[0070] During operation, the packaging bottles 100 to be sorted can be put into the bottle storage container 2, and the packaging bottles 100 in the bottle storage container 2 automatically fall into each bottle unscrambling and lifting channel 301 of the bottle unscrambling and lifting device 3, and are lifted to the front end opening of each bottle inlet groove 41 by each bottle unscrambling and lifting channel 301. The packaging bottles 100 entering each bottle inlet groove 41 slide backward along the corresponding bottle inlet groove 41 under the action of their own gravity, and then enter the corresponding variable-pitch chute 93 and are blocked by the first bottle-dividing baffle 95; after a row of packaging bottles 100 enters each variable-pitch chute 93, the second position switching mechanism 98 switches the position of the second bottle-dividing baffle 97, and the front end of each variable-pitch chute 93 is separated from the rear end of each bottle inlet groove 41 by the second bottle-dividing baffle 97;

[0071] Subsequently, the opening and closing control mechanism 90 drives the leftmost variable-pitch translation seat 92 and the rightmost variable-pitch translation seat 92 to translate toward each other, and drives the other variable-pitch translation seats 92 to move inwards through the retractable connecting rods 99 (at this time, the retractable connecting rods 99 are in a shortened state), thereby driving the variable-pitch chutes 93 and the packaging bottles 100 thereon to move inwards, so that the rear ends of the variable-pitch chutes 93 are respectively aligned with the rear ends of the corresponding bottle unscrambling troughs 5111; subsequently, The first position switching mechanism 96 switches the position of the first bottle dividing baffle 95, so that the first bottle dividing baffle 95 moves away from between the rear end of each variable pitch chute 93 and the front end of each bottle unscrambling groove 5111. At this time, the packaging bottles 100 in each variable pitch chute 93 slide down to each bottle unscrambling groove 5111 of the corresponding bottle lowering and turning unit 51 under the action of their own gravity, and reach the position matched with the limiting plate 512 of the packaging bottle 100, and the bottle mouth or bottle bottom is limited by the limiting plate 512 of the packaging bottle 100;

[0072] Subsequently, the bottle supporting movable plate 511 is driven by the swing mechanism 514 to swing downward around its side portion, and the bottle 100 limiting plate 512, the bottle supporting movable plate 511, and the bottle unscrambling bucket 513 cooperate to automatically flip a bottle 100 on the bottle supporting movable plate 511 to an upright state with the bottle mouth facing upward and the bottle bottom facing downward, thereby completing the automatic correction of the bottle mouth in the up and down direction of the bottle mouth of the bottle 100: if the bottle mouth of the bottle 100 in the bottle unscrambling groove 5111 faces downward and backward, Then, the mouth 101 of the packaging bottle 100 will be inserted into the corresponding bottle mouth limiting notch 5121. When the bottle supporting movable plate 511 swings downward, the mouth 101 of the packaging bottle 100 remains in the position limited by the bottle mouth limiting notch 5121, and the bottom of the packaging bottle 100 will gradually swing downward (the packaging bottle 100 swings downward around the bottle mouth with the bottle mouth limiting plate 512 as the fulcrum. When the bottle mouth of the packaging bottle 100 is separated from the bottle mouth limiting notch 5121, the bottle mouth 101 of the packaging bottle 100 will be lifted up and lowered. When the bottle bottom is below the bottle mouth, it will slide down along the lower inner wall of the bottle sorting bucket 513, so that the packaging bottle 100 is automatically corrected to an upright state with the bottle mouth facing upward and the bottle bottom facing downward; if the bottle mouth of the packaging bottle 100 on the bottle supporting movable plate 511 is tilted toward the front and upward, the bottle bottom of the packaging bottle 100 cannot pass through the bottle mouth limiting notch 5121 and is supported by the limiting plate 512. When the bottle supporting movable plate 511 swings downward around its side portion, the packaging bottle 100 is The bottle 100 slides down from the top, with the bottom of the bottle at the lower side of the bottle mouth, and then slides down along the lower inner wall of the bottle unscrambling bucket 513, so that the packaging bottle 100 is automatically corrected to an upright state with the bottle mouth facing upward and the bottle bottom facing downward, and falls out of the lower end of the bottle unscrambling bucket 513 onto the bottle feeding device 6 (at this time, the packaging bottle 100 enters the bottle body accommodating cavity from the top of the bottle body accommodating cavity, and is supported by the bottle supporting bottom plate 66, and the two left limiting rods 631 and the two right limiting rods 632 of the limiting rod group 63 jointly limit the bottle body of the packaging bottle 100);

[0073] Subsequently, the front-to-back translation mechanism 62 drives the bottle-feeding translation frame 61 and the two left-to-right translation mechanisms 65, the two second translation seats 64 and the respective limiting rod groups 63 to translate forward, and delivers the packaging bottles 100 in the respective limiting rod groups 63 to the position directly below the respective bottle mouth limiting sleeves 73; subsequently, the lifting mechanism 72 of the bottle mouth rotation and deviation correction mechanism 7 drives the lifting seat 71 and the rotating mechanism 74 and the bottle mouth limiting sleeves 73 to descend, so that the bottle mouth limiting sleeves 73 are sleeved on the packaging bottles 100 through the bottle mouth accommodating cavity 731 thereof. The bottle mouth portion 101 and the pull tab 102 of the packaging bottle 100 are placed on the bottle mouth portion 101 and the pull tab 102 (at this time, the bottle mouth portion 101 of the packaging bottle 100 will support the lower push block 747, so that the lower push block 747 and the bottle ejection push rod 745 move upward), and then the rotating mechanism 74 drives each bottle mouth limiting sleeve 73 to rotate one circle and then stop rotating. In this process, since the position of the bottle mouth limiting component 75 is lower than the bottle mouth limiting sleeve 73 and the bottle rotating block 732, it will not affect the rotation of the bottle mouth limiting sleeve 73, and no matter which direction the pull tab 102 at the bottle mouth of the packaging bottle 100 is facing, In each direction, the bottle rotating block 732 will drive the packaging bottle 100 to rotate after contacting the pull tab 102, until the pull tab 102 contacts the bottle mouth limiting component 75 and the packaging bottle 100 stops rotating, so that the pull tab 102 of the packaging bottle 100 faces a specific direction; then, the lifting mechanism 72 drives the lifting seat 71 and the rotating mechanism 74 and the bottle mouth limiting sleeve 73 thereon to rise and reset (at this time, the bottle ejector rod 745 and the lower ejector block 747 move downward under the action of their own gravity, and the bottle mouth portion 100 of the packaging bottle 100 is pressed against the bottle mouth portion 102). 1 applies a downward force so that the bottle mouth portion 101 can be smoothly separated from the bottle mouth limiting sleeve 73); then, the two left and right translation mechanisms 65 drive the two second translation seats 64 to translate, driving the two left limiting rods 631 and the two right limiting rods 632 of the limiting rod group 63 to move backwards, so that the distance between the left limiting rod 631 and the right limiting rod 632 becomes larger (usually larger than the size of the bottle body of the packaging bottle 100), so that the packaging bottle 100 can be moved out from between the left limiting rod 631 and the right limiting rod 632.
