Description

Technical Field

[0001] This invention relates to the field of telescopic machinery technology, specifically to an auxiliary device for a chain telescopic machinery used for unloading cigarettes. Background Technology

[0002] A telescopic conveyor refers to a telescopic belt conveyor, a logistics transport device that can freely extend and retract in length and adjust in height to a certain extent, and can transport materials in both directions. When used for loading and unloading vehicles, telescopic conveyors can shorten the distance that manual material handling can cover, reduce loading and unloading time, reduce labor intensity, minimize damage to goods, lower loading and unloading costs, and improve work efficiency.

[0003] Telescopic conveyors are commonly used in warehousing and e-commerce express logistics loading and unloading processes. They extend into the cargo compartment of trucks, automatically conveying goods from inside the compartment to the warehouse in a semi-automated system, facilitating unloading for workers. Alternatively, the end of the telescopic belt conveyor can be connected to a conveyor sorting line for automated operation. Telescopic conveyors are widely used in industries such as chemical, light industry, machinery, electronics, pharmaceuticals, food, tobacco, postal services, and warehousing terminals.

[0004] Cigarettes, as a type of item transported by telescopic conveyors, are made by rolling tobacco into strips using cigarette paper and then sealing them in cigarette boxes for storage. During the transport process using telescopic conveyors, multiple packs of cigarettes sealed into strips, or multiple strips of cigarettes sealed in boxes, move from one end of the telescopic conveyor belt to the other.

[0005] Patent document CN216971028U discloses an auxiliary device for a chain telescopic conveyor for unloading cigarettes. Before using the chain telescopic conveyor, the height of the support plate is adjusted by a lifting mechanism, allowing the support plate to support the extended end of the chain telescopic conveyor, thus preventing cigarette boxes from hitting the conveyor and falling from a height during unloading. When unloading cigarette boxes from a high position is required, one end of the guide plate is placed on the connecting hook plate on the support mechanism, and then the bolts on the limit plate are unscrewed. The guide plate is then activated by a power component. The end of the plate furthest from the support mechanism is lifted, causing the guide plate to tilt until the higher end of the guide plate reaches the appropriate position for unloading. During unloading, the cigarette box is placed on the guide plate, and under the action of gravity, the cigarette box slides down. The pulleys can accelerate the sliding of the cigarette box and reduce the friction between the cigarette box and the guide plate. The baffle is set to block the cigarette box and prevent it from falling outside the guide plate. Under the action of the guide plate, the cigarette box falls onto the chain telescopic mechanism on the support mechanism, and the chain telescopic mechanism transfers the cigarette box.

[0006] However, in the process of implementing the above technical solution, the following technical problems were found:

[0007] When the cigarette boxes are placed at an angle, they are difficult to place horizontally or vertically when protected by support plates. When using a telescopic conveyor for unloading, the telescopic ends are raised and extended sequentially to accommodate the height and distance of the unloading position. This allows workers to place the cigarette boxes on top of the innermost movable end for transport by the conveyor belt. However, in order to ensure unloading efficiency, workers do not control the angle of the cigarette boxes on the conveyor belt, which can easily lead to the cigarette boxes tilting. During the descent, they are difficult to be received and protected by the support plates, requiring manual handling. Summary of the Invention

[0008] To overcome the shortcomings of existing auxiliary devices for cigarette unloading chain telescopic conveyors, which tend to cause cigarette boxes to tilt when receiving them on the conveyor belt using a support plate, making it difficult for the support plate to receive and protect them during the descent phase and requiring manual handling, this application provides an auxiliary device for cigarette unloading chain telescopic conveyors. By having the cigarette packs transported by the telescopic conveyor to the top of the transition plate, they first come into contact with the straightening roller sleeve. Under the influence of the straightening spring, resistance is applied to the movement of the cigarette packs, which can correct the placement angle of the cigarette packs and allow them to continue moving. After the straightening roller sleeve drives the shaft seat and support slide plate to compress the straightening spring, the cigarette packs can be prevented from sliding on the top of the conveyor belt.

[0009] Meanwhile, by moving the cigarette pack from the top of the conveyor belt to the top of the transition plate, the transition plate is moved away from the hinge point between itself and the fixed base frame, thus causing the transition plate to rotate around the hinge point between itself and the fixed base frame and tilt towards the bottom, so that one end of it overlaps the receiving structure. This prevents the cigarette pack from falling from one end of the conveyor belt to the bottom, making it easier for the cigarette pack to be received at a horizontal and vertical angle without manual adjustment.

[0010] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0011] An auxiliary device for unloading cigarettes using a chain telescopic conveyor includes a release structure, a straightening structure, and a telescopic conveyor, wherein the straightening structure is located inside the release structure.

[0012] The cigarette pack box moves from one end of the telescopic conveyor to the other. The release structure and the correction structure are both located at one end of the telescopic conveyor. The top of the correction structure forms an obstruction on one side of the top of the cigarette pack box. The telescopic conveyor controls the movement of the cigarette pack box and corrects the placement angle of the cigarette pack box. After overcoming the resistance of the correction structure, the cigarette pack box moves from the top of the telescopic conveyor to the top of the release structure and is released to the bottom side under the control of the release structure.

[0013] In one possible implementation, the correction structure includes two symmetrical diagonal braces, one end of each of the two diagonal braces is machined with a support slide, a support slide plate is provided inside the support slide plate, a correction spring is provided at one end of the support slide plate, a bearing is machined on the top of the support slide plate, and a correction roller sleeve is provided between the two bearings.

[0014] In one possible implementation, the release structure includes a transition plate, with fixed base frames on both sides of one end of the transition plate, a support roller sleeve at the bottom of the transition plate, and support arms connected to both ends of the support roller sleeve via the same shaft. A connecting strip is machined between one end of the two support arms, and a tension spring is provided on one side of the connecting strip.

[0015] In one possible implementation, the telescopic conveyor includes a conveyor frame, with first bases machined at two corners at one end of the conveyor frame and second bases machined at two corners at the other end of the conveyor frame. Hydraulic push rods are hinged to one side of each of the two second bases. A frame is mounted on the top of the conveyor frame, and a conveyor belt is mounted on the top of the frame. An end plate is assembled to one end of the frame. The two sides of the frame near the release structure and the straightening structure are hinged to the top of the two first bases. One end of each of the two hydraulic push rods is hinged to the two sides of the other end of the frame.

[0016] In one possible implementation, both ends of the straightening roller sleeve are provided with positioning shafts. One end of the positioning shaft is machined with a mounting screw, and one end of the mounting screw is threadedly connected to a fixing nut. A limiting plate is machined on the outside of the positioning shaft. Bearings are embedded inside both sides of the shaft seat. One end of the positioning shaft is plugged into the inside of one end of the straightening roller sleeve. One side of the limiting plate is supported at the end face of the straightening roller sleeve. The mounting screw is sleeved inside the two bearings. One end of the positioning shaft and one side of the fixing nut are respectively supported at the inner ring of the two bearings.

[0017] In one possible implementation, the internal ends of the supporting slide plate are connected to limiting slide rods by pins, the internal parts of the supporting slide block are machined with receiving slide grooves and limiting slide grooves, one end of each of the two diagonal braces is respectively assembled and connected to the two ends of the end plate, the receiving slide grooves and limiting slide grooves are interwoven, the supporting slide plate is slidably connected to the inside of the receiving slide groove, and the two ends of the limiting slide rod are slidably connected to the inside of the limiting slide groove.

[0018] In one possible implementation, a positioning sleeve is machined at one end of the supporting slide plate, and an adjusting screw is sleeved to the outside of the positioning sleeve. A support plate is machined at one end of the adjusting screw, and a corrective spring is sleeved to the outside of the positioning sleeve. The corrective spring is supported between the surface of one end of the supporting slide plate and the surface of one side of the support plate.

[0019] In one possible implementation, a control handle is externally assembled to one end of the adjusting screw sleeve, the adjusting screw sleeve is threadedly connected to the inside of one end of the support slide, and the support plate is movably connected to the inside of the receiving slide groove and the outside of one end of the positioning sleeve rod.

[0020] In one possible implementation, the bottom supports of the two fixed base frames are machined with connecting plates, a first hook is machined on one side of the connecting bar, a second hook is machined on one side of the end plate, one end of the two support arms is hinged to the top of the connecting plate, one side of the two fixed base frames is respectively assembled and fixed to both ends of the end plate, and both ends of the tension spring are respectively hooked to the first hook and the second hook. The tension spring pulls the two support arms to rotate through the first hook and the connecting bar, so that the surface of the support roller sleeve is supported on the bottom end of the transition plate, and the support roller sleeve rotates outside its internal shaft.

[0021] The beneficial effects of this application are as follows:

[0022] Firstly, in this solution, during the process of transporting the cigarette packs to the top of the transition plate by the telescopic conveyor, they first come into contact with the straightening roller sleeve. Under the influence of the straightening spring support, resistance is applied to the movement of the cigarette packs, which can correct the placement angle of the cigarette packs and make them move continuously. After the straightening roller sleeve drives the shaft seat and support slide plate to compress the straightening spring, it can prevent the cigarette packs from sliding on the top of the conveyor belt, making it easy for the cigarette packs to be received at a horizontal and vertical angle without manual adjustment.

[0023] Secondly, in this solution, by moving the cigarette pack from the top of the conveyor belt to the top of the transition plate, the transition plate is moved away from the hinge point between itself and the fixed base frame, thus the transition plate rotates around the hinge point between itself and the fixed base frame and tilts to the bottom, so that one end of it overlaps the receiving structure, preventing the cigarette pack from falling from one end of the conveyor belt to the bottom. This helps to further ensure that the cigarette pack is received at a horizontal and vertical angle, which is simple and convenient.

[0024] Thirdly, in this solution, by adjusting the correction resistance applied to the cigarette pack by the correction spring through the bearing seat, mounting screw, positioning shaft and correction roller sleeve according to the actual correction requirements of the cigarette pack, the control screw sleeve can be rotated to adjust the threaded connection between the adjustment screw sleeve and the support slide, providing a means to adjust the compression of the correction spring between the support plate and the support slide plate, which is simple and convenient.

[0042] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0043] Example 1:

[0044] This embodiment describes the specific structure of an auxiliary device for a chain telescopic conveyor used for unloading cigarettes. See details below. Figures 1-11 As shown, it includes a release structure 3, a correction structure 4 disposed inside the release structure 3, and a telescopic conveyor 1;

[0045] Among them, the telescopic conveyor 1 is an existing device, which includes a conveyor base frame 103. A first base 102 is machined at two corners at one end of the conveyor base frame 103. After a second base 104 is machined at two corners at the other end of the conveyor base frame 103, the two sides of the telescopic conveyor 1 frame 106 near the release structure 3 and the straightening structure 4 are hinged to the top of the two first bases 102.

[0046] Meanwhile, one end of each of the two hydraulic push rods 105, which are respectively hinged to one side of the two second bases 104, is respectively hinged to the two sides of the other end of the frame 106. The top of the frame 106 is provided with a conveyor belt 101. When the telescopic conveyor 1 is used, referring to the existing control technology, the frame 106 is controlled to extend step by step, so that the transmission surface of the conveyor belt 101 is adapted to increase. The tilt angle of the movable end of the frame 106 is controlled by the hydraulic push rods 105 to control one end of the frame 106 to extend to a suitable height.

[0047] like Figure 2 , Figure 8As shown, the straightening structure 4 includes two symmetrical inclined support arms 403. One end of each of the two inclined support arms 403 is machined with a support slide 402. The support slide 402 is provided with a support slide plate 408 inside. One end of the support slide plate 408 is provided with a straightening spring 415. The top of the support slide plate 408 is machined with a bearing seat 407. A straightening roller sleeve 401 is provided between the two bearing seats 407.

[0048] The cigarette pack box 2 is located on top of the conveyor belt 101. Driven by the drive assembly inside the frame 106, it moves from the movable end to the fixed end of the frame 106, thus moving to one side of the straightening structure 4. When a corner of the cigarette pack box 2 contacts the surface of the straightening roller sleeve 401, it is supported by the straightening spring 415, which applies resistance to the movement of the cigarette pack box 2. As the cigarette pack box 2 continues to move, the placement angle of the cigarette pack box 2 is gradually corrected, and the straightening roller sleeve 401 drives the shaft seat 407 and the support slide plate 408 to compress the straightening spring 415, thus preventing the bottom end of the cigarette pack box 2 from sliding between the surface of the conveyor belt 101.

[0049] Secondly, in order to install the straightening roller sleeve 401 between the two bearing seats 407, as follows Figure 8 As shown, both ends of the straightening roller sleeve 401 are provided with positioning shafts 405. One end of the positioning shaft 405 is machined with a mounting screw 406. The outside of the positioning shaft 405 is machined with a limiting plate 404. By inserting one end of the positioning shaft 405 into the inside of one end of the straightening roller sleeve 401, and threading a fixing nut 410 to one end of the mounting screw 406, the bearing seat 407 can be mounted between the two bearing seats 407.

[0050] Meanwhile, in order to ensure that the straightening roller sleeve 401 can rotate between the two bearing seats 407, such as Figure 8 As shown, by embedding bearings inside both sides of the bearing seat 407, and with the mounting screw 406 passing through the inside of the bearing seat 407, one side of the limiting plate 404 is supported at the end face of the straightening roller sleeve 401. The mounting screw 406 is sleeved inside the two bearings, and can be supported at the inner ring of the two bearings by means of one end of the positioning shaft 405 and one side of the fixing nut 410. Relying on the characteristics of the bearings, the straightening roller sleeve 401 can rotate between the two bearing seats 407, which facilitates the bottom tilting of the contact position between the cigarette packaging box 2 and the straightening roller sleeve 401, and reduces frictional resistance.

[0051] Furthermore, in order to ensure the supporting slide plate 408 is stably supported by the corrective spring 415, and to compress the corrective spring 415 when correcting the placement angle of the cigarette pack box 2, such as... Figure 8As shown, the internal parts of both ends of the support slide plate 408 are connected by pins to limit slide rods 409. The internal parts of the support slide block 402 are machined with a receiving slide groove 5 and a limiting slide groove 6. By making the receiving slide groove 5 and the limiting slide groove 6 interlaced, the support slide plate 408 is slidably connected to the inside of the receiving slide groove 5, and the two ends of the limiting slide rod 409 are slidably connected to the inside of the limiting slide groove 6, which can restrict the up and down movement of the support slide plate 408 inside the receiving slide groove 5.

[0052] In some examples, to facilitate adjustment of the resistance applied by the straightening roller sleeve 401 to the cigarette packaging box 2, so that the cigarette packaging box 2, after being straightened, can smoothly fall between one end of the straightening roller sleeve 401 and the conveyor belt 101, such as... Figure 8 As shown, a positioning sleeve rod 411 is machined at one end of the supporting slide plate 408. An adjusting screw sleeve 412 is externally connected to the positioning sleeve rod 411. A support plate 413 is machined at one end of the adjusting screw sleeve 412. A control handle 414 is externally assembled at one end of the adjusting screw sleeve 412.

[0053] In this way, by connecting the corrective spring 415 to the outside of the positioning sleeve rod 411, after the corrective spring 415 is supported between the surface of one end of the support slide plate 408 and the surface of one side of the support plate 413, the corrective spring 415 can be restricted by the positioning sleeve rod 411 when it is compressed, thus avoiding bending and deformation.

[0054] Meanwhile, by threading the adjusting sleeve 412 to the inside of one end of the support slide 402, the threaded connection between the adjusting sleeve 412 and the support slide 402 can be adjusted when the adjusting sleeve 412 is rotated by the control lever 414. This does not affect the movable connection of the support plate 413 to the inside of the storage groove 5 or the outside of one end of the positioning sleeve rod 411, thus providing adjustment support for the straightening roller sleeve 401 to straighten the placement of the cigarette pack box 2.

[0055] Example 2:

[0056] Based on Example 1, this example describes the specific structure of the release structure 3, such as... Figure 3 , Figures 5 to 7 As shown, the release structure 3 includes a transition plate 301. Fixed base frames 303 are provided on both sides of one end of the transition plate 301. A support roller sleeve 302 is provided at the bottom of the transition plate 301. Support arms 304 are connected to both ends of the support roller sleeve 302 through the same shaft. A connecting strip 309 is machined between one end of the two support arms 304. A tension spring 308 is provided on one side of the connecting strip 309.

[0057] To facilitate the installation of the release structure 3 and the straightening structure 4 onto one end of the telescopic conveyor 1, such as... Figure 3As shown, one end of the frame 106 is assembled with an end plate 107. By assembling one end of the two diagonal braces 403 to the two ends of the end plate 107 respectively, and assembling and fixing one side of the two fixed base frames 303 to the two ends of the end plate 107 respectively, the straightening structure 4 and the release structure 3 can be fixed to the telescopic conveyor 1. Moreover, one end of the diagonal brace 403 leans against one side of the fixed base frame 303, which can enhance the integrity of the diagonal brace 403 and the fixed base frame 303 and improve the connection stability of the release structure 3 and the straightening structure 4 with the telescopic conveyor 1.

[0058] Secondly, the bottom supports of the two fixed base frames 303 are machined with connecting plates 305, and one end of the two support arms 304 is hinged to the top of the connecting plate 305. To facilitate the fixing of the tension spring 308 between the connecting bar 309 and the end plate 107, as follows... Figure 6 As shown, a first hook 306 is machined on one side of the connecting bar 309, and a second hook 307 is machined on one side of the end plate 107. By hooking the two ends of the tension spring 308 onto the first hook 306 and the second hook 307 respectively, the tension spring 308 can pull the two support arms 304 to rotate through the first hook 306 and the connecting bar 309, so that the surface of the support roller sleeve 302 is supported on the bottom end of the transition plate 301, keeping the surface of the transition plate 301 parallel to the surface of the conveyor belt 101, so that the cigarette pack box 2 can move smoothly from the top of the conveyor belt 101 to the top of the transition plate 301.

[0059] Meanwhile, when the transition plate 301 is pressed away from the hinge point between it and the fixed base frame 303, the transition plate 301 rotates around the hinge point between it and the fixed base frame 303 and tilts to the bottom, increasing the distance between the straightening roller sleeve 401 and the bottom of the transition plate 301, so that the cigarette pack box 2 slides down the surface of the transition plate 301 to the bottom. During this process, the support arm 304 rotates around the hinge point between it and the connecting plate 305, and the support roller sleeve 302 rotates outside its internal shaft and rolls at the bottom end of the transition plate 301.

[0060] Specifically, when using this chain telescopic conveyor auxiliary device for unloading cigarettes to unload cartons of cigarettes 2:

[0061] First, by utilizing the existing control methods of the telescopic conveyor 1, such as Figure 1As shown, the frame 106 extends step by step, and the transmission surface of the conveyor belt 101 adapts to the increase. The hydraulic push rod 105 is controlled to lift one end of the fixed end of the frame 106, so that the two sides of the frame 106 near the release structure 3 and the straightening structure 4 rotate around the hinge point with the top of the two first bases 102, thereby controlling the tilt angle of the multi-stage movable end extending from the inside of the fixed end of the frame 106, and finally controlling the height of the position where the cigarette pack 2 is placed, and so that the existing receiving structure of the cigarette pack 2 performs the receiving work at the bottom of the fixed end of the frame 106.

[0062] Then, the workers placed the cigarette pack boxes 2 one after another on top of the conveyor belt 101, causing the conveyor belt 101 to rotate cyclically under the existing drive components inside the frame 106, so that the cigarette pack boxes 2 could move from one end of the top of the telescopic conveyor 1 to the other end. Figure 9 As shown, when the cigarette pack 2 moves to one side of the straightening structure 4 and a corner of the pack contacts the surface of the straightening roller sleeve 401, it is supported by the straightening spring 415 inside the receiving chute 5, which applies resistance to the movement of the cigarette pack 2. Furthermore, as the cigarette pack 2 continues to move, as... Figure 10 As shown, the placement angle of the cigarette pack box 2 is gradually corrected, and the correcting roller sleeve 401 drives the shaft seat 407 and the support slide plate 408 to move, so that the support slide plate 408 compresses the correcting spring 415 on one side of the support plate 413, and the positioning sleeve rod 411 slides inside the adjusting screw sleeve 412, so as to prevent the bottom end of the cigarette pack box 2 from sliding between the bottom end of the cigarette pack box 2 and the surface of the conveyor belt 101.

[0063] At the same time, after the cigarette pack box 2 overcomes the resistance of the straightening spring 415 through the straightening roller sleeve 401, the bearing seat 407 and the support slide plate 408, as Figure 11 As shown, the transition plate 301 moves from the top of the conveyor belt 101 to the top of the transition plate 301. After the transition is completed, the transition plate 301 is pressed away from the hinge point between it and the fixed base frame 303. This compresses the tension spring 308, which is connected between the connecting plate 305 and the connecting bar 309 by the first hook 306 and the second hook 307. This causes the transition plate 301 to be supported by the support roller sleeve 302 between one end of the two support arms 304. The transition plate 301 rotates around the hinge point between it and the fixed base frame 303. The support roller sleeve 302 rotates outside its inner shaft, which stretches the tension spring 308 connected between the first hook 306 and the second hook 307 and tilts it to the bottom. One end of the spring overlaps the receiving structure, which can prevent the cigarette pack box 2 from falling from one end of the conveyor belt 101 to the bottom.

[0064] During this process, one end of the positioning shaft 405 and one side of the fixing nut 410 are respectively supported at the inner ring of the two bearings, while the mounting screw 406 is sleeved into the inside of the two bearings, and the other end of the positioning shaft 405 is inserted into the inside of one end of the straightening roller sleeve 401. Relying on the characteristics of the bearings, the straightening roller sleeve 401 rotates between the two bearing seats 407. When the distance between the straightening roller sleeve 401 and the bottom of the transition plate 301 increases, the frictional resistance applied by the straightening roller sleeve 401 to the top surface of one side of the cigarette packaging box 2 is small. As the cigarette packaging box 2 tilts, the thrust applied to the straightening roller sleeve 401 gradually increases, thereby facilitating the tilting of the contact position between the cigarette packaging box 2 and the straightening roller sleeve 401 towards the bottom, so that the cigarette packaging box 2 slides down the surface of the transition plate 301 to the bottom.

[0065] Next, when the position correction of a single cigarette pack 2 is completed, the compressed correction spring 415 moves back to its original position outside the positioning sleeve 411, pushing the support slide plate 408 to slide back to its original position inside the receiving slide 5 under the cooperation of the two limiting slide rods 409 and the limiting slide groove 6. Thus, the correction roller sleeve 401 is driven to reset by the bearing seat 407, the mounting screw 406 and the positioning shaft 405. If two adjacent cigarette packs 2 are corrected at the same time, the cigarette pack 2 transported first is corrected by the correction roller sleeve 401, and the cigarette pack 2 transported later is corrected by the cigarette pack 2 transported first. It is worth noting that during the unloading of multiple cigarette packs 2, there will be no two cigarette packs 2 stacked on top of the telescopic conveyor 1 or two cigarette packs 2 leaning tightly together.

[0066] At the same time, the connecting bar 309 is pulled by the tension spring 308 and controls the two support arms 304 to rotate with the help of the first hook 306, so that the surface of the support roller sleeve 302 is supported on the bottom end of the transition plate 301, keeping the surface of the transition plate 301 parallel to the surface of the conveyor belt 101, so that the cigarette packaging box 2 in the subsequent conveying process can move smoothly from the top of the conveyor belt 101 to the top of the transition plate 301.

[0067] Furthermore, during the normal operation of the release structure 3 and the straightening structure 4, the adjustment sleeve 412 can be rotated by controlling the control lever 414, and the threaded connection between the adjustment sleeve 412 and the support slide 402 can be adjusted. This allows for adjustment of the compression of the straightening spring 415 between the support plate 413 and the support slide plate 408. This facilitates adjusting the resistance applied to the cigarette packaging box 2 by the straightening spring 415 through the bearing seat 407, the mounting screw 406, the positioning shaft 405, and the straightening roller sleeve 401, according to the actual straightening requirements of the cigarette packaging box 2.
