Description

[Technical field]

[0001] The utility model belongs to the technical field of cup dropping equipment, in particular to an automatic cup dropping device with high versatility. [Background technology]

[0002] Cup packaging is widely used in the food industry and the beverage industry. The competition in food packaging machinery is becoming increasingly fierce. In the future, food cup packaging machinery will cooperate with industrial automation. Therefore, an automatic cup dropping device needs to be set in the automated equipment, which is mainly used to automatically separate the vertically stacked cups in an orderly manner and provide subsequent loading vessels. For example, a cup dropping device disclosed in Chinese Patent Publication No. CN219098106U includes a frame and a cup separation mechanism. The frame is provided with a stacking guide rail for vertically stacking cups. The cup separation mechanism is arranged below the stacking guide rail. The cup separation mechanism includes a cup dropping rotating seat with a cylindrical outer circumference and a rotating driving mechanism. The rotating driving mechanism is used to drive the cup dropping rotating seat to rotate. The outer circumference of the cup dropping rotating seat is provided with a cup entry notch, a dislocation guide rail, and a cup exit notch. The cup entry notch, the dislocation guide rail, and the cup exit notch are sequentially downward vertically and are sequentially connected. The dislocation guide rail is arranged in a ring shape, and the cup entry notch and the cup exit notch are vertically dislocated. Although the above scheme can realize automatic cup dropping, there are still the following problems:

[0003] (1) The outer circumference of the cup-dropping rotating seat is provided with a cup-entry notch, an offset guide rail, and a cup-discharging notch from top to bottom in sequence. The cup-entry notch and the cup-discharging notch are vertically offset, and first guide surfaces are provided on both sides of the cup-dropping rotating seat along the circumference of the cup-dropping rotating seat, and second guide surfaces are provided on both sides of the cup-discharging notch along the circumference of the cup-dropping rotating seat. The cup-dropping rotating seat has to meet multiple functional requirements, so its design structure is relatively complex, which makes the processing technology of the cup-dropping rotating seat complex. In addition, the current cups are all light and thin, which leads to high processing accuracy requirements for the cup-dropping rotating seat, increasing the production cost. Moreover, when replacing cups of different sizes, the cup-dropping rotating seat needs to be replaced as a whole, which has poor versatility. Therefore, different cup-dropping rotating seats need to be prepared according to cups of different sizes or thicknesses, which leads to high production costs.

[0004] (2) The stacking guide rails are generally distributed in a horizontal straight line, which is only suitable for linear filling machines and not for disc-type filling machines.

[0005] Therefore, it is necessary to provide a highly versatile automatic cup dropping device to solve the above technical problems. [Contents of the utility model]

[0036] Please refer to Figure 1-Figure 9 The present embodiment is a highly versatile automatic cup dropping device, which comprises a frame 1, a cup rack 2 disposed on the frame 1 and used for storing vertically stacked cups 200, a cup separation module 3 correspondingly disposed below the cup rack 2, and a rotating drive mechanism 4 for driving the cup separation module 3 to rotate so as to achieve a cup dropping action; there are two cup separation modules 3 corresponding to each cup rack 2, and the two cup separation modules 3 are relatively disposed on the left and right sides of the cup rack 2, and the cup separation module 3 comprises a rotating seat 31 for blocking the lowest cup 200 and a toggle support plate 32 for separating the lowest cup 200 from the second-to-last cup 200 and supporting the second-to-last cup 200 at the same time.

[0037] In the present embodiment, three cup racks 2 are provided and the three cup racks 2 are arranged in a triangular structure. Correspondingly, three pairs of cup dividing modules 3 are provided. The inner pair of cup dividing modules 3 are arranged along the X direction, and the outer two pairs of cup dividing modules 3 are arranged along the Y direction. The three pairs of cup dividing modules 3 are arranged in two rows. The three pairs of cup dividing modules 3 are compactly arranged and suitable for disc-type filling equipment. Three cups 200 can be filled at the same time, which can improve production efficiency.

[0038] The cup rack 2 includes a plurality of guide posts, which together enclose a vertical passage for accommodating the cup 200. The cup 200 is stacked in the cup rack 2 with the opening facing upward. The rack 1 includes a through hole 11 corresponding to the cup 200 falling and an avoidance hole for avoiding the cup separation module 3, which is opened at the bottom of the cup rack 2. The avoidance hole is provided with an opening on the side facing the through hole 11 so that the avoidance hole is connected with the through hole 11, so that the cup separation module 3 can enter the through hole 11 from the opening to block the cup 200 or separate the cups, thereby realizing the cup dropping action. A support platform 14 is provided at the lower end of the rack 1, and the through hole 11 and the avoidance hole are provided on the support platform 14. All the cup separation modules 3 are located in the avoidance hole and the lower end is slightly higher than the support platform 14. The lower surface of the support platform 14 is a plane and a disc mold plate is provided below, so that the cup 200 can fall completely into the disc mold plate. The frame 1 is also provided with a sensor for sensing whether a cup 200 is placed in the cup rack 2 .

[0039] A storage bin 21 for temporarily storing cups 200 is provided on one side of the cup holder 2. The storage bin 21 includes a cup slot 211 arranged at an angle to the horizontal axis. One end of the cup slot 211 opens toward the cup holder 2 and the other end is provided with a limiting plate 212 for limiting the cup 200 in the cup slot 211.

[0040] The rotary drive mechanism 4 includes a plurality of rotary shafts 41 rotatably arranged on the frame 1 for mounting a plurality of cup-dispensing modules 3, a driven wheel 42 fixed to the upper end of the rotary shaft 41, a rotary drive member 43 mounted on the frame 1, and a driving wheel 44 driven to rotate by the rotary drive member 43. The driving wheel 44 and the driven wheel 42 are connected together by a transmission belt 45 to realize rotary transmission.

[0041] A plurality of bearings 46 are arranged on the outer periphery of the rotating shaft 41. The rotating shaft 41 is mounted on the frame 1 through the bearings 46. A limiting sleeve 49 is arranged between two adjacent bearings 46 to limit the bearings 46. The bearings 46 can make the rotating shaft 41 run smoothly and flexibly, and can limit the position of the rotating shaft 41. When there is mechanical loss and the load changes, the rotating shaft 41 can still maintain its original position. The driven wheel 42 is fixed to the upper end of the rotating shaft 41 by a key.

[0042] The rotating shaft 41 is provided with a mounting boss 411 for mounting the cup-dispensing module 3 , and the mounting boss 411 is provided with a threaded hole 412 .

[0043] A tensioning wheel 47 for controlling the tensioning force of the transmission belt 45 is rotatably arranged between two adjacent driven wheels 42. The tensioning wheel 47 is rotatably arranged on a pin shaft 48. The lower end of the pin shaft 48 is installed on the frame 1. One or two tensioning wheels 47 are arranged between two adjacent driven wheels 42. The number of tensioning wheels 47 can be increased or decreased according to the distance between the driven wheels 42, which is not limited here.

[0044] The cup-dividing module 3 is roughly cylindrical and is installed on the lower surface of the mounting boss 411. A mounting hole 33 is provided in the middle of the cup-dividing module 3 to cooperate with the lower end of the rotating shaft 41. The cup-dividing module 3 is also provided with a waist-shaped hole 34 which is opposite to the threaded hole 412 up and down. The cup-dividing module 3 is inserted into the lower end of the rotating shaft 41 through the mounting hole 33 and contacts with the lower surface of the mounting boss 411. Bolts or pins are then inserted into the threaded hole 412 and the waist-shaped hole 34 to fix the cup-dividing module 3 on the lower surface of the mounting boss 411, thereby realizing the installation and fixation of the cup-dividing module 3 and the rotating shaft 41.

[0045] The support plate 32 is fixed to the upper end of the rotating seat 31 through a cylindrical pin 35 .

[0046] The rotating seat 31 is generally cylindrical in structure. A cup outlet notch 36 extending from the upper end face to the lower end face is arranged on the outer periphery of one side of the rotating seat 31. The cup outlet notch 36 is formed by cutting a vertical plane from the upper end face to the lower end face of the rotating seat 31, so that the cup 200 can fall from this point. Therefore, when the two cup outlet notches 36 of the two corresponding cup dispensing modules 3 are opposite to each other, the distance between the two cup outlet notches 36 is greater than the diameter of the cup mouth 201. An annular groove 37 for avoiding the cup mouth 201 is arranged on the outer edge of the upper end of the rotating seat 31. The vertical height of the annular groove 37 is similar to the vertical height of the cup mouth 201. The side of the annular groove 37 opposite to the cup outlet notch 36 is a cup inlet 38 for the cup 200 to fall into. After the cup 200 falls into the cup, the cup mouth 201 is supported on the groove bottom of the annular groove 37 at the cup inlet 38. Therefore, when the two cup inlets 38 of the two corresponding cup dispensing modules 3 are opposite to each other, the distance between the two cup inlets 38 is smaller than the diameter of the cup mouth 201. The vertical height of the annular groove 37 is similar to the vertical height of the cup mouth 201, so that only one cup 200 falls into the cup inlet 38 each time, and the rotating seat 31 can rotate at the cup inlet 38 to extend into the through hole 11 to support the cup 200.

[0047] The rotating seat 31 includes a first mounting hole centrally arranged and matched with the lower end of the rotating shaft 41 , a first waist-shaped hole vertically opposite to the threaded hole 412 , and a first cylindrical hole matched with the cylindrical pin 35 .

[0048] The toggle support plate 32 is a disc structure, and includes a second mounting hole that is mounted in cooperation with the lower end of the rotating shaft 41 and is opposite to the first mounting hole up and down, a second waist-shaped hole that is opposite to the threaded hole 412 up and down and is opposite to the first waist-shaped hole up and down, and a second cylindrical hole that is matched with the cylindrical pin 35 and is connected to the first cylindrical hole up and down. The second mounting hole is arranged offset from the center of the toggle support plate 32, so that the toggle support plate 32 is eccentrically arranged above the rotating seat 31. Therefore, one side of the toggle support plate 32 is provided with a toggle support portion 324 extending from the cup outlet notch 36 and extending into the through hole 11 to separate the bottommost cup 200 from the penultimate cup 200 and simultaneously support the penultimate cup 200, and the other opposite side of the toggle support portion 324 is located on the inner side of the annular groove 37 so that the cup 200 can fall into the cup inlet 38. The eccentric arrangement of the toggle support plate 32 can not only realize the falling of the cup 200, but also separate the cups and support the cup 200 at the same time.

[0049] The circumferential outer edge of the support plate 32 is provided with a guide surface 325 which can be smoothly inserted into the two cup openings 201. The thickness of the guide surface 325 increases gradually from the outer edge to the inner side so that the support plate 32 can smoothly enter between the two cup openings 201. The increasing thickness can separate the bottom cup 200 from the second to last cup 200, so that the bottom cup 200 can fall smoothly.

[0050] If the thickness of the cup 200 remains unchanged, and only the diameter of the cup body 202 and the diameter of the cup mouth 201 are changed when changing the cup 200 of different sizes, the position of the rotating seat 31 and the support plate 32 can be adjusted to adapt to different sizes without the need for overall replacement, and the versatility is higher.

[0051] When the highly versatile automatic cup dropping device 100 provided by the present solution is used, the cup 200 is placed in the storage bin 21, and the cup 200 is pushed toward the cup rack 2. The cup 200 enters the cup rack 2 and moves upward along the column of the cup rack 2 so that all the cups 200 in the storage bin 21 enter the vertical channel in the cup rack 2, and the cups 200 are stacked in the cup rack 2 with their openings facing upward. The rotary drive mechanism 4 starts to work, and the rotary drive member 43 drives the driving wheel 44 to drive the rotary shaft 41 to rotate so that the cup inlets 38 of the cup dispensing modules 3 on both sides are opposite to each other. At this time, the lowest cup 200 is blocked at the two cup inlets 38, and the cup mouth 201 of the lowest cup 200 is supported on the groove bottom of the annular groove 37 at the cup inlet 38. The driving member 43 drives the driving wheel 44 to drive the rotating shaft 41 to rotate so that the two cup outlet notches 36 of the cup dividing modules 3 on both sides are opposite to each other. During the rotation of the cup dividing module 3, the support plate 32 is gradually inserted horizontally between the cup mouth 201 of the bottom cup 200 and the cup mouth 201 of the second to last cup 200. When the support plate 32 is moved to be opposite to each other, the bottom cup 200 is squeezed downward while supporting the second to last cup 200. At this time, since the two cup outlet notches 36 are opposite to each other, the horizontal insertion depth of the moving support part 324 is the deepest. After the support plate 32 is moved to squeeze the bottom cup 200 downward, the bottom cup 200 automatically falls from the cup outlet notch 36 and falls onto the mold plate below (not shown in the figure), completing the cup dropping action.

[0052] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
