Description

Technical Field

[0001] The utility model relates to material sorting equipment, in particular to a device for replenishing special-shaped square cigarettes in whole pieces, and more particularly to a sorting and replenishing device. Background Art

[0002] In the field of logistics, sorting equipment is indispensable, and sorting equipment is also used for sorting cigarette strips. The size of conventional cigarette strips is generally 27.5cm*8.5cm*4cm, and general sorting equipment can quickly and automatically sort this size of cigarette strips. However, in actual terminal delivery, not only ordinary-sized cigarette strips are needed, but also various types of special-shaped cigarettes and square cigarettes. These types of cigarettes are sorted into ordinary cigarette strips for subsequent packaging. As for the sorting of special-shaped and square cigarettes, the conventional method is to manually put the cigarettes into the cigarette bin in stacks in units of strips, and then according to the terminal order requirements, the corresponding number of cigarette strips are taken out and mixed into the normal cigarette strips. This method of replenishing special-shaped square cigarettes is inefficient and the labor intensity of the operators is relatively high. At the same time, the existing method of replenishing cigarettes in the cigarette bin is to push the cigarette strips in from the side. Due to the different sizes of different special-shaped and square cigarettes, the pushing force is difficult to control, resulting in the cigarette strips being unable to be centered when they are added to the main conveyor line, causing the sorting system to frequently alarm and requiring manual processing.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0039] Example 1: See Figure 1-7 As shown, a device for replenishing special-shaped square cigarettes in one piece comprises a frame 1, a cigarette loading mechanism 2, a conveying line 3, a separating mechanism 4 and a cigarette dropping mechanism 5 which are sequentially arranged on the frame from left to right;

[0040] The smoke loading mechanism 2 includes a smoke loading portion 21, a first conveyor belt 22, and a first driving cylinder 23. The right end of the smoke loading portion 21 is rotatably connected to the frame 1. The first driving cylinder 23 drives the smoke loading portion 21 to rotate around the frame 1. The first conveyor belt 22 is provided at the bottom of the smoke loading portion 21.

[0041] The separation mechanism 4 includes a longitudinal pushing mechanism and a transverse pushing mechanism. The longitudinal pushing mechanism is provided with a longitudinal pushing plate 41 that moves forward and backward, and the transverse pushing mechanism is provided with a cigarette pushing plate 42 that moves transversely.

[0042] The cigarette dropping mechanism 5 includes a cigarette bin 51 and a cigarette supporting plate 52. The cigarette bin 51 is arranged opposite to the cigarette pushing plate 52, and the cigarette supporting plate 52 is arranged in the cigarette bin 51; a supporting plate cylinder 53 is provided on the outer wall of the cigarette bin 51, and the supporting plate cylinder 53 is configured to drive the cigarette supporting plate 52 to move, so that the cigarette supporting plate 52 extends into the cigarette bin 51 or exits the cigarette bin 51.

[0043] In this embodiment, in actual use, the cigarette bin is set directly above the main sorting line. In this way, cigarettes that fall from the cigarette bin can fall in the middle of the main sorting line, which can solve the problem of irregularly shaped cigarettes and square cigarettes not being sorted in the center and reduce the alarm frequency of the sorting system. During the cigarette replenishment process, multiple unpacked and stacked cigarettes (or multiple cigarettes sorted in sequence) can be placed in the upper cigarette section manually, by a conveyor belt, or by a robot. Then, the first drive cylinder drives the upper cigarette section to rotate so that the top surface of the first conveyor belt is facing the conveyor line. At this time, the stacked cigarettes will abut against the first conveyor belt. The first conveyor belt will feed the cigarettes to the right onto the conveyor line. The conveyor line will then feed the cigarettes to the right into the separation mechanism. The stacked cigarettes are first pushed backwards by the longitudinal push plate to between the cigarette bin and the cigarette push plate. The cigarette push plate then moves horizontally to the right to push them into the cigarette bin. The cigarette support plate supports at least one cigarette stacked from bottom to top. Then, according to the cigarette replenishment signal, when cigarette replenishment is needed, the output shaft of the support plate cylinder retracts, driving the cigarette support plate to move outward, causing the cigarette support plate to exit the cigarette bin. At this time, the cigarette strips lack support and will fall downward onto the main sorting line, realizing the cigarette replenishment action. In this way, according to the position of the cigarette bin, the cigarette replenishment position can fall directly above the main sorting line, making the main sorting line less likely to cause an alarm. At the same time, according to the different sizes of special-shaped cigarettes and square cigarettes, corresponding-sized cigarette replenishment devices can be installed on the main sorting line. Then, the same cigarette replenishment device can replenish special-shaped cigarettes and square cigarettes of corresponding sizes, realizing automatic cigarette replenishment.

[0044] In this embodiment, the length of the replenishing bin is greater than the length of the cigarette carton, and the width is adapted to or slightly greater than the width of the cigarette carton. If the width of the conveyor line is the width of three cigarette cars, the width of the rack at the grading mechanism is the width of four cigarette cars. The width of three cigarette cars of the rack at the separating mechanism is directly opposite the right end of the conveyor line, and the width of the last cigarette carton of the rack at the separating mechanism is located behind the right end of the conveyor line, directly opposite the cigarette push plate and the bin.

[0045] See also Figure 1-3 As shown, the interior of the smoke-loading section 21 has a chamber 24, the top and right side of the chamber 24 are respectively connected to the top and right side of the smoke-loading section 21, the first conveyor belt 22 is arranged at the bottom of the chamber 24, and the frame 1 is provided with a first conveying motor 25, which is configured to drive the first conveyor belt 22;

[0046] The fixed end at the bottom of the first driving cylinder 23 is rotatably connected to the frame 1, and the output shaft at the top of the first driving cylinder 23 is rotatably connected to the bottom of the smoke raising part 21;

[0047] When the output shaft of the first driving cylinder is extended, the right end of the chamber is arranged opposite to the left end of the conveying line; when the output shaft of the first driving cylinder is retracted, the chamber is arranged toward the left side.

[0048] In this embodiment, the first driving cylinder is an air cylinder. When the output shaft of the first driving cylinder is extended, the top surface of the first conveyor belt is flush with the top surface of the conveyor line, and the right end of the first conveyor belt is close to the left end of the conveyor line. At this time, the top surface of the first conveyor belt is parallel to the horizontal plane. When it is necessary to load cigarettes, the output shaft of the first driving cylinder retracts, driving the cigarette loading section to rotate counterclockwise, so that the chamber faces left, and the original left inner wall of the chamber is at the bottom. At this time, a robot, a conveyor line or manual labor can be used to put the cigarettes into the chamber. It will use the original left inner wall of the chamber to support the cigarettes. This method is particularly convenient for manual loading. Of course, it is also suitable for conveyor belts of lower heights to deliver the unpacked cigarettes to the chamber of the cigarette loading section. The most convenient way is: after unpacking the box, place the cigarette strips in a vertical state directly on the left inner wall of the chamber (the left inner wall of the chamber is facing downward at this time), and then lift the box to separate the cigarette strips and the box, and the cigarette strips are in the chamber. Then the output shaft of the first drive cylinder extends, pushing the upper cigarette part to rotate clockwise, so that the originally vertically arranged cigarette strips can be placed flat on the first conveyor belt, and then the first conveying motor drives the top of the first conveyor belt to the right, and the cigarette strips in the chamber are sent to the right to the conveyor line, and then the cigarette strips are transported to the right through the conveyor line.

[0049] See also Figure 1-3 As shown, the conveyor line 3 includes a plurality of at least two second conveyor belts 31 arranged sequentially from left to right, with a slight gap between two adjacent second conveyor belts 31, and the top plane of each second conveyor belt 31 is arranged on the same plane;

[0050] The frame 1 is provided with second motors 32 corresponding one to one with the second conveyor belts 31 , and each second motor 32 is configured to drive the corresponding second conveyor belt 31 and transport the top of the second conveyor belt toward the right.

[0051] In this embodiment, the conveyor line includes three secondary conveyor belts arranged sequentially from left to right. By providing multiple secondary conveyor belts, each can be used to temporarily store cigarette cartons, giving the loading section ample time to load cigarettes, preventing problems such as missing cigarettes due to insufficient loading time and the need for manual restocking. Furthermore, different secondary conveyor belts can be used to store different cigarette cartons based on the order, allowing for the placement of a cigarette restocking device on the main sorting line, reducing costs.

[0052] In this utility model, the chamber has drive rollers at both ends. The first conveyor belt is wound around the two drive rollers, and the first motor drives one of the drive rollers to rotate, so that the top of the first conveyor belt is driven to the right and the cigarettes are transported to the conveyor line. Each second conveyor belt is also wound around the two drive rollers, and each second motor also drives a drive roller to rotate, driving the top of the second conveyor belt to the right, and then driving the cigarettes above it to be transported to the adjacent second conveyor belt on the right, or to the frame at the separation mechanism.

[0053] See also Figure 2-4 As shown, the longitudinal pushing mechanism includes a longitudinal pushing plate 41 and a longitudinal driving part, and the longitudinal driving part includes a longitudinal guide rod 43, a longitudinal lead screw 44 and a longitudinal motor 45. Both ends of the longitudinal guide rod 45 and the longitudinal motor 45 are installed on the frame 1, and the longitudinal lead screw 44 is arranged parallel to the side of the longitudinal guide rod 43, and both ends of the longitudinal lead screw 44 are rotatably connected to the frame 1; wherein, the longitudinal guide rod and the longitudinal lead screw are arranged perpendicular to the transmission direction of the conveyor line, and are arranged longitudinally.

[0054] The top of the longitudinal push plate 41 is slidably connected to the longitudinal guide rod 43 via a longitudinal slider 46, and the longitudinal screw 44 is screwed to the longitudinal slider 46. The longitudinal motor 45 is configured to drive the longitudinal screw 44 to rotate and drive the longitudinal push plate 41 to move forward and backward.

[0055] The transverse pushing mechanism includes a cigarette pushing plate 42, a transverse cylinder 47 and a transverse slide 48. The transverse slide 48 is arranged on the rear side of the longitudinal push plate 41. The top of the cigarette pushing plate 42 is slidably connected to the transverse slide 48 via a transverse slider 49. The transverse cylinder 47 is installed on the frame 1. The output shaft at the right end of the transverse cylinder 47 is connected to the transverse slider 49. The transverse cylinder 47 drives the cigarette pushing plate 42 to move left and right.

[0056] When the horizontal cylinder output shaft retracts, the right end plane of the cigarette pushing plate is arranged on the left side of the left end plane of the longitudinal push plate; when the horizontal cylinder output shaft extends, the right end of the cigarette pushing plate is inserted into the cigarette bin.

[0057] In this embodiment, a right baffle 401 is set on the frame at the right end of the longitudinal push plate. The distance between the baffle and the second conveyor belt on the far right is slightly larger than the length of the cigarette strip. The rear end of the right baffle is in contact with the front side of the left end of the cigarette bin. A rear baffle 402 is set at the rear end of the longitudinal push plate, and the right end of the rear baffle is connected to the rear end of the left side of the cigarette bin. In the initial state, the longitudinal push plate moves at the front end, which is at the front side of the right end of the conveyor line, and the cigarette pushing plate is at the left end. After the conveyor line transports the cigarettes to the right to the rear end of the longitudinal push plate (taking the conveyor line as an example, which can place 3 rows of cigarettes in sequence from front to back, then the frame at the separation mechanism can be spaced from front to back to prevent at least 4 rows of cigarettes), the longitudinal motor drives the longitudinal screw to rotate and pushes the longitudinal push plate to move backward. The backward movement of the longitudinal push plate pushes the cigarettes backward and against the rear baffle, so that the last row of cigarettes faces the cigarette bin, wherein, there is a vertical channel 54 in the cigarette bin 51, and the upper left side of the vertical channel is connected to the left side wall of the cigarette bin, and the bottom of the vertical channel is connected to the bottom of the cigarette bin, and the vertical channel faces the cigarette pushing plate. When the last row of cigarettes hits the rear baffle, the output shaft of the horizontal cylinder extends, pushing the row of cigarettes (each row of cigarettes includes at least one cigarette, or at least multiple cigarettes stacked from below) to the right and into the vertical slot of the cigarette bin, where the bottom of the group of cigarettes is supported by the cigarette support plate. Then, according to the cigarette replenishment signal, when cigarette replenishment is needed, the output shaft of the support plate cylinder retracts, driving the cigarette support plate to move outward, causing the cigarette support plate to exit the cigarette bin. At this time, the group of cigarettes lacks support and will fall downward onto the main sorting line, completing the cigarette replenishment action.

[0058] Furthermore, an extension support plate 55 is provided on the left side of the cigarette bin 51, and is disposed on the upper left side of the cigarette support plate 52. The extension support plate serves to support the cigarettes as they are pushed rightward by the cigarette push plate into the vertical passage of the cigarette bin, thereby extending the support distance for the cigarettes and allowing the cigarettes to be smoothly supported by the cigarette support plate.

[0059] See also Figure 4-7 As shown, the cigarette supporting plates 52 and supporting plate cylinders 53 are respectively provided in two groups. A through slot 56 communicating with the vertical channel is respectively provided on the front side wall and the rear side wall of the cigarette bin 51. Each supporting plate cylinder 53 is respectively mounted on the frame 1 outside a group of through slots 56. The outer end of each cigarette supporting plate 52 is connected to the output shaft of the corresponding supporting plate cylinder 53.

[0060] When the output shaft of the support plate cylinder is extended, the cigarette support plate passes through the through slot and is arranged in the vertical channel; when the output shaft of the support plate cylinder is retracted, the support plate moves outward and leaves the vertical channel.

[0061] Two groups of cigarette supporting plates are used, which are driven by a group of supporting plate cylinders to move in and out, so that the cigarette supporting plates can be inserted into the vertical channel or detached from the vertical channel. When the output shaft of the supporting plate cylinder is extended, the cigarette supporting plate is in the vertical channel, and the top plane height of the cigarette supporting plate will be slightly lower than the top plane height of the extended supporting plate, so that when the cigarette pushing plate pushes the cigarette to the right, the bottom of the cigarette can be smoothly supported by the cigarette supporting plate. And the two cigarette supporting plates support the front and back sides of the bottom of the cigarette respectively. When the cigarette needs to be dropped (replenished), the output shafts of the two groups of supporting plate cylinders retract at the same time, so that the two cigarette supporting plates are separated from the cigarette at the same time. Compared with the method of setting the cigarette supporting plate only on one side, when the single-sided cigarette supporting plate is separated from the cigarette, the cigarette will tilt to one side, which may cause the cigarette to be stuck in the vertical channel, that is, smoke blockage occurs. The two supporting plates are set to separate from the cigarette strip synchronously, so that the cigarette strip will not tilt, and will not get stuck or blocked, thus ensuring the normal dropping and replenishing of cigarettes.

[0062] In the present invention, the cigarette bin is positioned directly above the main sorting line, which transports cigarettes from front to back or back to front. The bottom of the vertical channel faces the main sorting line, and there is no obstruction to the bottom of the vertical channel. This arrangement is particularly suitable for transporting one cigarette at a time. That is, each group of cigarettes contains only one cigarette, there is only one cigarette on the right side of the cigarette push plate, and there is only one cigarette in the vertical channel of the cigarette bin at a time. When the cigarette support plate is separated from the vertical channel, only one cigarette falls onto the main sorting line. Alternatively, the arrangement is suitable for replenishing a predetermined number of cigarettes at a time, that is, the cigarette bin can simultaneously place 2-5 cigarettes onto the main sorting line at a time.

[0063] However, this efficiency will be relatively low (only one cigarette is released at a time, and the speed will be relatively slow), or the cigarettes will be stacked on the main sorting line and affect the subsequent normal sorting. Therefore, in order to improve the efficiency of cigarette replenishment and prevent it from affecting the subsequent normal sorting, a support plate 61 is further provided on the frame below the cigarette bin, and there is a vertical distance between the support plate 61 and the bottom of the cigarette bin 51; the support plate 61 is also provided with a cigarette falling groove 62, and the cigarette falling groove 62 is arranged on the front side of the cigarette bin 51.

[0064] The support plate 61 is provided with a smoke drop component, which includes a smoke drop plate 63, a smoke drop cylinder 64 and a smoke drop guide rod 65. The smoke drop guide rod 65 is longitudinally arranged on the left side of the smoke drop groove 62. The smoke drop plate 63 is arranged on the rear side of the smoke drop groove 62 and is arranged within the vertical spacing between the support plate 61 and the smoke bin 51.

[0065] One end of the smoke falling plate 63 is slidably connected to the smoke falling guide rod 65 via the smoke falling slider 66, the fixed end of the smoke falling cylinder 64 is connected to the frame 1, and the output shaft of the smoke falling cylinder 64 is connected to the smoke falling slider 66. The smoke falling cylinder drives the smoke falling plate to move forward and backward, so that the smoke falling plate is close to or away from the smoke falling groove.

[0066] The distance between the support plate and the bottom of the cigarette bin is slightly greater than the thickness of a cigarette. Each time the push plate pushes a group of cigarettes into the bin and is held by the support plate, the group is relatively large, at least two cigarettes, and can be stacked from bottom to top. In this method, after the output shaft of the support plate cylinder retracts, the support plate disengages from the vertical channel, and multiple cigarettes fall downward. The bottommost cigarette passes through the support plate, while the upper cigarettes remain in the bin. Then, according to the cigarette replenishment signal, the output shaft of the cigarette drop cylinder retracts and extends as a cigarette replenishment action. When the output shaft of the cigarette drop cylinder retracts, it drives the cigarette drop plate to move forward, and the cigarette drop plate pushes the bottom cigarette forward and enters the cigarette drop trough. The sorting main line passes under the support plate, and the cigarette falls from the cigarette drop trough to the sorting main line. At the same time, the cigarette drop plate will be below the vertical channel, blocking the cigarette above. Then the output shaft of the cigarette drop cylinder extends, driving the cigarette drop plate to move backward and leave the vertical channel of the cigarette bin. Since the cigarettes in the cigarette bin lose the limit of the cigarette drop plate, they will automatically fall under the weight. The bottom cigarette falls onto the support plate and waits for the next cigarette replenishment action, and the cycle repeats. In this way, the cigarette bin can be replenished continuously, so that there are always cigarettes in the vertical channel of the cigarette bin. The movement of the cigarette drop plate can realize the delivery of one cigarette to the sorting main line at a time, which has high sorting efficiency, no stacking, and does not affect the normal sorting of the sorting main line. It has good stability.
