A rapid cup sorting device for thermoforming plastic cups

Abstract

The present invention relates to the technical field of cup sorting machines, and more specifically to a rapid cup sorting device for thermoforming plastic cups, comprising a frame, a material guide plate, a material collecting mechanism, a conveying mechanism, a distance adjusting mechanism, a toggle mechanism, a direction adjusting mechanism, and a shaking mechanism. The present invention provides a distance adjusting mechanism, so that when the cups stacked in the collecting trough reach a preset length, the cups in the corresponding conveying channel are moved upward, and the toggle mechanism toggle them to other conveying channels, thereby making the number of sorted cups in multiple collecting troughs similar. This solves the problem of excessive difference in the number of cups in different channels in the prior art, and improves the cup sorting efficiency. Furthermore, since the lengths of the sorted cups in the collecting trough tend to be consistent in the front-to-back direction, the rear end is pushed by the cups, and the front end abuts against the induction block, so that the cups are stacked more tightly, achieving a better cup sorting effect. This solves the problem in the prior art that sorted cups become loose and detached under the action of the shaking mechanism, and are not stacked tightly enough.

Description

Technical Field

[0001] The invention relates to the technical field of cup unscrambling machines, and in particular to a fast cup unscrambling device for thermoforming plastic cups. Background Art

[0002] A cup sorter is a mechanical device specifically designed for collecting and organizing disposable cups. Its core function is to quickly and accurately arrange and stack the disorganized cups on the production line. It usually receives the cups via a conveyor belt and uses cleverly designed guide rails, baffles, or rotating mechanisms to quickly straighten and align the cups in various postures, ultimately outputting them in an orderly and stable queue or stack. Traditional cup sorting devices require manual collection and bagging after the cups are sorted, which is labor-intensive and inefficient.

[0003] To this end, patent publication number CN211495547U discloses a highly efficient cup sorting machine that automatically transfers and collects stacked plastic cups, resolving the inefficiency and high cost of traditional manual collection methods. However, during the sorting process, the cup sorting devices described in the aforementioned patent and prior art often have inconsistent numbers of cups in different channels. When stacking cups in a channel, some channels may have a large number of stacked cups, making it impossible to receive subsequent cups, while other channels may have fewer organized cups. Consequently, the number of cups in multiple channels varies significantly. Furthermore, during the stacking process, the cups may not be stacked tightly enough, resulting in loose cups. This necessitates secondary sorting for subsequent transfer, leading to low cup sorting efficiency. Summary of the Invention

When the length of the cups stacked in the collecting trough reaches a preset value, the distance adjusting mechanism reduces the width of the conveying channel corresponding to the collecting trough. Since the cup body is tapered, the cup moves upward in the process of gradually reducing the width of the conveying channel. However, since the distance between the lower end of the shifting mechanism and the conveying mechanism is less than the distance the cup moves upward, the cups in the conveying channel with reduced width are shifted to other channels and moved to other collecting troughs, so that the distances of the cups stacked in multiple collecting troughs in the front-to-back direction tend to be consistent, thereby making the number of sorted cups in multiple collecting troughs similar, solving the problem of excessive difference in the number of cups in different channels of the cup sorting device in the prior art, and improving the cup sorting efficiency of the cup sorting device.

[0026] In addition, since the lengths of the sorted cups in the trough tend to be consistent in the front-to-back direction, the front end abuts against the sensing block. During the subsequent movement of the cups toward the trough, a forward force is applied to the sorted cups in the trough, thereby making the cups in the trough stacked more tightly. This solves the problem in the prior art that the cups sorted by the cup sorting device are not stacked tightly enough and are loose and detached, and has a better cup sorting effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0051] like Figures 1 to 13 As shown, a rapid cup sorting device for thermoforming plastic cups provided by an embodiment of the present invention includes a frame 100, a material guide plate 200, a material collecting mechanism 300, a conveying mechanism 400, a distance adjustment mechanism 500, a toggle mechanism 600, a direction adjustment mechanism 700 and a shaking mechanism 800.

[0052] The guide plate 200 is tilted, with the rear end higher than the front end, and is fixedly connected to the frame 100; the guide plate 200 is used to receive cups produced from the production machine, and the cups include a tapered cup body and a cup rim.

[0053] The material collecting mechanism 300 includes a plurality of partition plates 310; the partition plates 310 are vertically arranged and fixedly connected to the front of the frame 100; the plurality of partition plates 310 are spaced apart along the left and right directions, and two adjacent partition plates 310 define a material collecting trough 320; the width of the material collecting trough 320 is greater than the diameter of the cup rim.

[0054] There are multiple conveying mechanisms 400, which are spaced apart in the left-right direction and correspond to multiple aggregate troughs 320 respectively; the conveying mechanism 400 includes two conveying units, which define a conveying channel; the width of the conveying channel is equal to the maximum diameter of the cup body, but smaller than the diameter of the cup rim; the rear end of the conveying mechanism 400 is lower than the front end of the guide plate 200; the conveying mechanism 400 is used to convey the cup to the aggregate trough 320.

[0055] The conveying unit includes a first rotating wheel 410, a second rotating wheel 420, a third rotating wheel 430 and a conveying bar 440; a first rotating shaft, a second rotating shaft and a third rotating shaft are rotatably installed on the frame 100; the first rotating shaft is located below the guide plate 200, and the first rotating shaft is connected to a conveying drive member, which can be a motor; the second rotating shaft is located between the guide plate 200 and the collecting mechanism 300, and the height of the second rotating shaft is higher than the first rotating shaft; the third rotating shaft is located behind the guide plate 200, and the first rotating wheel 410 is synchronously rotated and installed on the first rotating shaft; the second rotating wheel 420 is synchronously rotated and installed on the second rotating shaft; the third rotating wheel 430 is synchronously rotated and installed on the third rotating shaft; the first rotating wheel 410, the second rotating wheel 420 and the third rotating wheel 430 are all provided with mounting grooves on their circumferences, and the conveying bar 440 passes through the mounting grooves on the first rotating wheel 410, the second rotating wheel 420 and the third rotating wheel 430 in sequence, and the conveying bar 440 is in a tensioned state.

[0056] There are multiple distance adjustment mechanisms 500, each corresponding to the multiple conveying mechanisms 400. The distance adjustment mechanism 500 is used to reduce the width of the corresponding conveying channel when the cups stacked in the collecting trough 320 reach a preset length in the front-to-back direction, so that the cups engaged in the conveying channel move upward by a preset distance.

[0057] The shifting mechanism 600 is arranged between the material guide plate 200 and the material collecting mechanism 300; the distance between the lower end of the shifting mechanism 600 and the conveying mechanism 400 is smaller than the distance the cup body moves upward when the width of the conveying channel is reduced.

[0058] The direction adjustment mechanism 700 is provided at the front side of the toggle mechanism 600 . The direction adjustment mechanism 700 is used to adjust the cup passing over the toggle mechanism 600 to an inclined state with the cup opening facing forward and upward.

[0059] The shaking mechanism 800 is arranged below the rear end of the collecting trough 320 and is used to drive the cups at the rear end of the collecting trough 320 to shake back and forth up and down.

[0060] After the cups are produced, they are transferred to the guide plate 200. Under the action of gravity, the cups slide forward and downward along the guide plate 200 and fall onto the conveyor bar 440. Some cups are clamped between the two third rotating wheels 430 under the action of their own gravity, with the cup edges overlapping the conveyor bar 440; some cups have their cup bodies overlapping the conveyor bar 440, and some cups have their axes perpendicular to the conveyor bar 440 and are overlapping the conveyor bar 440 with their bottoms facing upwards. The motor drives the first rotating shaft to rotate, thereby driving the first rotating wheel 410 thereon to rotate synchronously. Under the action of the conveying bar 440, the second rotating wheel 420 and the third rotating wheel 430 are driven to rotate synchronously, thereby conveying the cups thereon to the collecting mechanism 300. During the conveying process of the conveying mechanism 400, the shifting mechanism 600 shifts the cups located above the conveying bar 440 so that the cups passing through the shifting mechanism 600 all face upward. Thereafter, the adjusting mechanism 700 changes the orientation of the cups passing through the shifting mechanism 600, adjusting them to an inclined state with the cup mouth facing forward and upward, and maintains the inclined state before reaching the collecting mechanism 300.

[0061] The cups keep moving forward, and the cups behind push the cups in front forward. The cups enter the collecting trough 320. The shaking mechanism 800 shakes the cups on it back and forth, so that the bottom of the cup in front is inserted into the rim of the cup behind. As the conveying work proceeds, the cups are stacked on each other, and the length of the cups in the collecting trough 320 in the front-to-back direction gradually increases. When the length reaches a preset value, the distance adjustment mechanism 500 reduces the width of the conveying channel corresponding to the collecting trough 320. Due to the tapered shape of the cup body, as the width of the conveying channel gradually decreases, the cups However, because the distance between the lower end of the toggle mechanism 600 and the conveying mechanism 400 is less than the distance the cups move upward, the cups in the conveying channel with a reduced width are toggled to other channels and moved to other collection troughs 320, making the distance between the stacked cups in the multiple collection troughs 320 in the front-to-back direction closer together. This, in turn, makes the number of stacked cups in the multiple collection troughs 320 similar. In addition, during the subsequent forward conveying of cups, a forward force is applied to the stacked cups, making the cups in the collection trough 320 stacked more tightly. This solves the problem of excessive discrepancies in the number of cups in different channels of the cup sorting device in the prior art, as well as the problem of the stacked cups not being tightly enough or being loose and detached, thereby improving the cup sorting efficiency of the cup sorting device and the efficiency of subsequent cup transfer.

[0062] In a further embodiment, the width of the mounting grooves on the first rotating wheel 410 and the second rotating wheel 420 is greater than twice the diameter of the conveying bar 440; the width of the mounting groove on the third rotating wheel 430 is equal to the diameter of the conveying bar 440; the third rotating wheel 430 is mounted on the frame 100 for left-right movement; and the distance adjustment mechanism 500 is used to move the corresponding two third rotating wheels 430 closer to each other when the cups stacked in the chute 320 reach a preset length in the front-to-back direction.

[0063] The distance adjustment mechanism 500 includes an induction component, a return spring 510 and two movable guide plates 520; an adjustment plate 530 is provided on the rear side of the partition plate 310, the adjustment plate 530 is vertically arranged and fixedly connected to the frame 100; and is located between two adjacent conveying mechanisms 400; the left and right sides of the adjustment plate 530 are symmetrically provided with slide grooves 531, the slide grooves 531 are inclined, and the distance between the two slide grooves 531 toward one end of the guide plate 200 is smaller than the distance between the two ends toward the partition plate 310.

[0064] The two movable guide plates 520 are arranged at intervals on the left and right, and the movable guide plates 520 are arranged between the adjustment plate 530 and the third rotating wheel 430. A slider 521 is fixedly connected to the side of the movable guide plate 520 facing the adjustment plate 530. The slider 521 is arranged at an angle, and the slider 521 is slidably installed in the slide groove 531. The slope of the slider 521 is consistent with the slope of the corresponding slide groove 531; in the initial state, the slider 521 is inserted into the slide groove 531; the return spring 510 is arranged between the two third rotating wheels 430 of the same conveying mechanism 400, and the return spring 510 makes the two third rotating wheels 430 tend to move away from each other, so that the width of the conveying channel is exactly equal to the maximum diameter of the cup body. At this time, the lower surface of the cup rim of the cup overlaps the conveying bar 440.

[0065] The sensing component is used to drive the movable guide plate 520 corresponding to the collecting trough 320 to move forward when the length of the stacked cups in the collecting trough 320 in the front-to-back direction reaches a preset value.

[0066] During the cup sorting process, when the cups in the collection chute 320 are stacked to a predetermined length, the sensing assembly drives the corresponding movable guide plate 520 forward. Due to the interaction between the chute 531 and the slider 521, the movable guide plates 520 move forward and approach each other. As the two movable guide plates 520 approach each other, they drive the two third rotating wheels 430 toward each other, compressing and accumulating force in the return spring 510. The distance between the conveying bars 440 near the third rotating wheel 430 decreases. As the third rotating wheel 430 continues to rotate, the distance between the conveying bars 440 passing through the third rotating wheel 430 gradually decreases, thereby driving the conveying bars 440 on the first rotating wheel 410 to move along the axial direction of the first rotating wheel 410 and approach each other. Thereafter, the conveying bars 440 on the second rotating wheel 420 move along the axial direction of the first rotating wheel 410 and approach each other. The cup originally located behind the toggle mechanism 600 gradually moves upwards during the process of narrowing the width of the conveying channel between the first rotating wheel 410 and the second rotating wheel 420. When the cup contacts the toggle mechanism 600, it is toggled to another conveying channel. Afterwards, the conveying bars 440 between the third rotating wheel 430 and the second rotating wheel 420 are moved upwards. Figure 11 The status shown first changes to Figure 12 The state shown then changes to Figure 13 The cups originally located in front of the toggle mechanism 600 have already been moved to the collection trough 320 before the width of the conveying channel between the second rotating wheel 420 and the third rotating wheel 430 changes. The number of cups in the collection trough 320 no longer changes, and the cup sorting work of the collection trough 320 is completed.

[0067] In a further embodiment, the sensing assembly includes a sensing block 540 and two sensing steel wires 550; the sensing block 540 is installed on the frame 100 for forward and backward movement and is located at the front end of the frame 100; the two sensing steel wires 550 correspond to the two movable guide plates 520 respectively, one end of the sensing steel wire 550 is fixedly connected to the movable guide plate 520, and the other end is fixedly connected to the sensing block 540.

[0068] During the cup sorting process, the number of cups in the hopper 320 gradually increases, the length of the cups in the hopper 320 in the front-to-back direction gradually increases, and the distance between the frontmost cup and the sensing block 540 gradually decreases. When the cups stacked in the hopper 320 reach a preset length, the frontmost cup contacts the sensing block 540, but the cups on the conveying bar 440 between the second rotating wheel 420 and the third rotating wheel 430 continue to move forward under the action of the conveying bar 440, exerting a forward force on the cups stacked in the hopper 320, so that the cups in the hopper 320 are stacked more tightly.

[0069] When the cups in the hopper 320 are stacked tightly and continue to be pushed by subsequent cups, the cups drive the sensing block 540 to move forward. When the sensing block 540 moves, the corresponding two movable guide plates 520 are driven to move forward synchronously through the sensing wire 550. The movable guide plates 520 drive the third rotating wheels 430 at the corresponding positions to move closer to each other, thereby reducing the width of the conveying channel, so that cups no longer enter the conveying channel.

[0070] After the cups in the hopper 320 are taken out, the sensing block 540 corresponding to the hopper 320 is no longer pushed by the cups, and the return spring 510 releases its elastic force, causing the corresponding two third rotating wheels 430 to move away from each other. When the third rotating wheels 430 move away from each other, they push the two movable guide plates 520 away from each other. With the cooperation of the sliding groove 531 and the slider 521, the movable guide plates 520 move away from each other and move backward synchronously, and pull the sensing block 540 to move backward to restore to its initial state. The conveying channel corresponding to the hopper 320 restores its initial width, and then the hopper 320 can carry out cup sorting work.

[0071] In a further embodiment, the toggle mechanism 600 includes a toggle shaft 610 and a toggle plate 620; the toggle shaft 610 extends in the left and right directions and is rotatably installed on the frame 100, and the toggle shaft 610 is connected to a motor; the toggle plate 620 extends radially along the toggle shaft 610 and is evenly distributed and fixedly connected to the toggle plate 620 along the circumference of the toggle shaft 610; the distance between the end of the toggle plate 620 away from the toggle shaft 610 and the conveying bar 440 is less than the distance the cup body moves upward when the width of the conveying channel is narrowed.

[0072] The steering mechanism 700 includes a steering assembly 710 and a support assembly 720, arranged in order from back to front. The steering assembly 710 adjusts the angle between the cup axis and the conveyor bar 440, thereby aligning the cup's rim with the front and the top. The support assembly 720 maintains the cup's rim facing forward and upward. The steering assembly 710 includes a plurality of steering rods 711 extending left and right, spaced apart in the front-to-back direction. The steering rods 711 are located below and in front of the second rotating wheel 420, tilting the cup so that the rim faces upward and forward after the cup passes through.

[0073] The bottom support assembly 720 includes multiple first supporting wheels 721, multiple second supporting wheels 722 and multiple supporting bars 723; the frame 100 is rotatably installed with a first supporting shaft and a second supporting shaft, both of which extend in the left and right directions; the first supporting shaft is located below the adjustment grid, and the second supporting shaft is located below the partition plate 310; the number of first supporting wheels 721 and second supporting wheels 722 is the same; at least one first supporting wheel 721 and one second supporting wheel 722 are arranged below each conveying channel; the first supporting wheel 721 and the second supporting wheel 722 are respectively mounted on the first supporting shaft and the second supporting shaft for synchronous rotation; the bottom bar 723 passes through the first supporting wheel 721 and the second supporting wheel 722 and is in a tensioned state; the first supporting shaft is connected to the bottom driving member, which is a motor, which drives the first supporting shaft to rotate and makes the bottom bar 723 and the conveying bar 440 move at the same speed.

[0074] After the cups are produced, they slide from the guide plate 200 onto the conveyor bar 440. The motors are activated, and the motors drive the first rotating shaft, the first supporting shaft, and the shifting shaft 610 to rotate about their respective axes. Under the action of their own weight, some cups on the conveyor bar 440 are clamped between the two third rotating wheels 430, with their rims overlapping the conveyor bar 440. Some cups have their bodies overlapping the conveyor bar 440, while others have their axes perpendicular to the conveyor bar 440, with their bottoms facing upwards. The first rotating shaft drives the first rotating wheel 410 to rotate, which in turn drives the conveyor bar 440. As the conveyor bar 440 conveys the cups, the shifting shaft 610 drives the shifting plate 620 on it to rotate, continuously shifting the cups in contact with it until the cups are clamped between the conveyor channels and their rims overlap the conveyor bar 440. The cups then pass between the shifting plate 620 and the conveyor bar 440.

[0075] After that, the conveyor bar 440 drives the cup to continue moving forward. The cup body continues to move forward under the action of the friction between the cup and the conveyor bar 440, but the bottom of the cup is blocked by the adjustment rod 711 and cannot move synchronously with the cup body. At this time, the angle between the cup and the conveyor bar 440 is reduced, and the cup mouth faces forward and upward. By setting multiple adjustment rods 711, it is ensured that all cups that pass the adjustment rod 711 are facing forward and upward; the cup that passes the frontmost adjustment rod 711 has a tendency to rotate, but when rotating, it is blocked by the bottom support bar 723, and the moving speeds of the conveyor bar 440 and the bottom support bar 723 are equal. The cup keeps the cup mouth facing forward before moving to the collection trough 320.

[0076] In a further embodiment, the shaking mechanism 800 includes a shaking shaft and multiple cams 810; the shaking shaft extends in the left and right directions, and the shaking shaft is rotatably installed on the frame 100, and the shaking shaft is located below the rear end of the partition plate 310; the cam 810 is synchronously rotatably installed on the shaking shaft, and the multiple cams 810 are arranged at intervals along the left and right directions, and are respectively located in multiple aggregate troughs 320; the shaking shaft is connected to a motor.

[0077] After the cup enters, the shaking shaft drives the cam 810 to rotate synchronously. From the time when the remote point of the cam 810 contacts the cup at the rear end of the collection trough 320 to the time when the remote point reaches the highest position, the cup is pushed upward. After the remote point passes the highest position, the cup moves downward under the action of its own gravity. As the cam 810 continues to rotate, the cup shakes back and forth up and down, and the cup at the back moves forward, is sleeved on the outside of the cup in front, and is stacked in the collection trough 320. When the length of the cups stacked in the collection trough 320 reaches a preset value, the sensing block 540 is pushed forward, prompting the sensing block 540 to move forward. The sensing wire 550 and the movable guide plate 520 drive the third rotating wheel 430 at the corresponding position to approach each other, thereby narrowing the width of the conveying channel and preventing the cup from entering the conveying channel.

[0078] In a further embodiment, a conveyor belt is provided at the front end of the frame 100; push blocks are provided on the left and right sides of the frame 100, and the push blocks are installed on the frame 100 for sliding up and down. A push plate is installed between the two push blocks for sliding back and forth, and the push plate has an insertion portion for inserting into the aggregate trough 320. In the initial state, the lower end of the push plate is located above the aggregate trough 320.

[0079] The frame 100 is slidably mounted with a moving block, which is fixedly connected to a plurality of mounting shafts. The sensing blocks 540 are respectively mounted on the plurality of mounting shafts so as to move forward and backward. The moving block is connected to a driving member, which may be a hydraulic cylinder.

[0080] When the width of all conveying channels is reduced, the motor connected to the first rotating shaft is turned off to stop conveying the conveying bar 440; and the driving member is started. The driving member drives the sensing member to disengage from the frontmost cup in the hopper 320 via the moving block and the mounting shaft, prompting the push block to move downward by a preset distance, so that the insertion portion of the push plate extends into the rear end of the hopper 320. Thereafter, the push plate moves forward to push the cups in the hopper 320 toward the transmission belt, which drives the stacked cups to be transferred to the next process.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
