Description

Technical Field

[0001] The present invention relates to the technical field of material transfer, and in particular to a mechanically actively triggered double conveyor belt transfer device and a transfer method. Background Art

[0002] The use of logistics transfer devices not only improves the efficiency and economy of logistics transportation, but also promotes the sustainable development of the logistics industry through technological innovation and green energy-saving design, which is of great significance to environmental protection and social and economic development.

[0003] Transfer devices are widely used between two sets of conveyor belts. Mechanical handling replaces manual handling, reducing the amount of manual work.

[0004] Specifically, the existing transfer device realizes the grabbing and lifting of materials by combining two sets of driving modes. The driving directions of the two driving modes are arranged vertically. One set is responsible for clamping the materials, and the other set is responsible for lifting the materials to separate from the conveyor belt to prevent the materials from scratching against the conveyor belt during the transfer process, resulting in unstable material clamping. Most of these two driving modes use separate driving sources, which makes the structure of the transfer device more complicated and more expensive. In addition, the two sets of driving sources require specific driving programs to perform corresponding actions. Once a program error occurs, the transfer device cannot work normally. Moreover, the above-mentioned driving sources are mostly hydraulic, which leads to higher precision requirements for the stroke of the hydraulic device during the clamping process. Inaccurate stroke will directly cause the material to be squeezed and deformed or unable to be stably clamped. Summary of the invention

[0033] A method of using the mechanically actively triggered dual conveyor belt transfer device as described, comprising the following steps:

[0034] Step 1: When the material moves to a predetermined position on one of the conveyor belts, the electric telescopic rod starts to move, so that the engaging wheel can move along the No. 1 horizontal groove, the No. 2 vertical groove, the No. 2 horizontal groove and the No. 1 vertical groove under the action of the switching structure;

[0035] Step 2: When the engaging wheel moves along the No. 1 horizontal groove, the abutting wheel can abut against the abutting plate, and drive the two clamping plates to move away from each other. When the engaging wheel moves along the No. 2 vertical groove, the two clamping plates remain away from each other and move downward at the same time. When the engaging wheel moves along the No. 2 horizontal groove, the two clamping plates move toward each other to clamp the material. When the engaging wheel moves along the No. 1 vertical groove, the two clamping plates can lift the material.

[0036] Step 3: The linear drive module drives the transverse moving part to move along the length direction of the beam, and under the action of the pressure component, the No. 3 spring is further stretched to increase the clamping force between the two clamping plates;

[0037] Step 4: The traverse member continues to move, and then under the action of the deflection assembly, the rotation axis rotates 180°;

[0038] Step 5: When the material moves to a predetermined position on another conveyor belt, the electric telescopic rod moves again, allowing the engaging wheel to move along the No. 1 horizontal groove, so that the two clamping plates move away from each other and slowly release the material.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] The material is clamped by the elastic force provided by the No. 3 spring. Compared with the clamping method using a cylinder, hydraulic cylinder or other driving method in the prior art, it can effectively avoid the phenomenon that the material is compressed and deformed or cannot be stably clamped due to the influence of the stroke accuracy of the cylinder, hydraulic cylinder or other driving methods;

[0041] Only a single electric telescopic rod can be used to clamp, lift and release materials, which reduces the number of driving sources used. On the one hand, it can reduce the production and use costs of the device. On the other hand, the mechanical coordination can improve the stability of the device operation and avoid the occasional disorder of the action sequence caused by the use of a driver to control multiple driving sources, so that the transfer process can be carried out stably and orderly.

[0042] Reducing the span of the beam can, on the one hand, avoid physical deformation of the beam when the transverse member carries the material and prevent metal fatigue of the beam; on the other hand, it can reduce the space occupancy rate of the device, so that the device can be used in a relatively small space;

[0043] When the material switches its position, the clamping force of the clamping plate on the material is increased, which can avoid the separation of the material and the clamping plate caused by the centrifugal force generated when the material makes a circular motion to switch its position, further improving the stability during the transfer process. When the material completes the position switch, the clamping force of the two clamping plates will return to the initial state, thereby avoiding the deformation of the material under the action of long-term large clamping force and reducing the damage to the material structure during the transfer process.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0056] See also Figure 1 to Figure 9 In an embodiment of the present invention, a mechanically actively triggered dual conveyor belt transfer device includes: a guide plate 11, an electric telescopic rod 10, a switching structure, a side plate 20 and a lifting plate 27, so that only a single electric telescopic rod 10 can be used to clamp, lift and release the material, reducing the number of driving sources used. On the one hand, it can reduce the production and use costs of the device, and on the other hand, the mechanical coordination can improve the stability of the device operation, and avoid the occasional disorder of the action sequence caused by the use of a driver to control multiple driving sources, so that the transfer process can be carried out stably and orderly, as follows:

[0057] The guide plate 11 is formed with a "mouth"-shaped groove. Specifically, the "mouth"-shaped groove includes a first vertical groove 1101 and a second vertical groove 1102 and a first horizontal groove 1103 and a second horizontal groove 1104 arranged in parallel. The first vertical groove 1101, the first horizontal groove 1103, the second vertical groove 1102 and the second horizontal groove 1104 are connected end to end in sequence.

[0058] The electric telescopic rod 10 is rotatably mounted on a rotating shaft 4 connected to a guide plate 11, and an engaging wheel 15 is rotatably mounted on an action end of the electric telescopic rod 10. Specifically, the electric telescopic rod 10 is tilted and rotatably connected to a support beam 402 on the rotating shaft 4.

[0059] The switching structure is arranged at the connection between the first vertical slot 1101 and the first horizontal slot 1103 and the second vertical slot 1102 and the second horizontal slot 1104, and the switching structure can make the engaging wheel 15 move along the track of the "mouth"-shaped slot when the electric telescopic rod 10 moves;

[0060] The switching structure includes two retractable parts 12 that can slide along the length direction of the No. 1 horizontal groove 1103 and the No. 2 horizontal groove 1104. The retractable parts 12 are slidably connected to the horizontal axis 13 arranged on the guide plate 11. A No. 2 spring 14 is sleeved on the horizontal axis 13. One end of the No. 2 spring 14 is connected to the end of the horizontal axis 13, and the other end is connected to the retractable part 12.

[0061] In the initial state, the electric telescopic rod 10 is in a tilted state, so that when the electric telescopic rod 10 is controlled to move at this time, the action end of the electric telescopic rod 10 will drive the engaging wheel 15 to move along the length direction of the No. 1 horizontal groove 1103, and then after the engaging wheel 15 moves to the end of the No. 1 horizontal groove 1103, the engaging wheel 15 will move along the No. 2 vertical groove 1102, and after the engaging wheel 15 moves to the end of the No. 2 vertical groove 1102, the engaging wheel 15 will abut against the contraction piece 12 at the lower end of the No. 2 vertical groove 1102, and drive the contraction piece 12 to move along the length direction of the No. 2 horizontal groove 1104, and compress the No. 2 spring 14, until the engaging wheel 15 moves to the connection between the No. 2 vertical groove 1102 and the No. 2 horizontal groove 1104, the contraction piece 12 will be compressed. The retracting member 12 will be reset, and when the action end of the electric telescopic rod 10 is retracted, the engaging wheel 15 will move along the second horizontal groove 1104 again, and when the engaging wheel 15 moves to the end of the second horizontal groove 1104, the engaging wheel 15 will move into the first vertical groove 1101 again, and when the engaging wheel 15 moves to the end of the first vertical groove 1101, the engaging wheel 15 will abut against another retracting member 12, and drive the retracting member 12 to retract, so that the engaging wheel 15 can be reset, and the engaging wheel 15 can move along the trajectory of the "mouth"-shaped groove, and after the engaging wheel 15 is reset, when the electric telescopic rod 10 performs the telescopic action again, the above process can be repeated, so that the movement path of the engaging wheel 15 has the characteristics of fixedness and repeatability.

[0062] In the above process, when the electric telescopic rod 10 is extended or retracted, the engaging wheel 15 has two completely different motion states, which are specifically manifested as follows:

[0063] One is that the engaging wheel 15 first moves horizontally and then moves downward, the horizontal movement can drive the clamping structure to open, and the downward movement can make the clamping structure change in height;

[0064] The second is that the engaging wheel 15 first moves in the reverse horizontal direction and then moves upward. The reverse horizontal direction movement can close the clamping structure to clamp the material, while the upward direction movement can lift the material through the clamping structure.

[0065] The significance of the above process is that the clamping structure can move upward after completing the clamping of the material, and the material can be separated from the conveyor belt during the material transfer process, avoiding dragging and causing material breakage or separation of the material from the clamping structure, thereby improving the stability of material transfer.

[0066] See also Figure 6~Figure 8The side plate 20 is fixedly connected to the guide plate 11, and a lifting member connected to the electric telescopic rod 10 is slidably mounted on the side plate 20. The lifting member is slidably arranged in a No. 1 slide groove 2001 formed on the side plate 20. The lifting member includes a connecting frame 19 connected to the lifting plate 27 and a transverse plate 18. A No. 1 engaging groove 1801 is arranged on the transverse plate 18, and a groove wheel 16 coaxially connected to the engaging wheel 15 can roll in the No. 1 engaging groove 1801;

[0067] The lifting plate 27 is connected to the connecting frame 19. A clamping structure is provided on the lifting plate 27. The abutment wheel 17 installed on the electric telescopic rod 10 cooperates with the clamping structure, so that when the electric telescopic rod 10 moves, the clamping structure can perform opening and releasing and closing and clamping actions.

[0068] The clamping structure includes a second slide groove 2701 provided on the lifting plate 27, a slider 25 is slidably installed in the second slide groove 2701, a clamping plate 26 is connected to the slider 25, and a connecting plate 24 is connected to the slider 25;

[0069] The clamping structure further includes a guide rod 2002 disposed on the side plate 20, an abutment plate 22 is slidably mounted on the guide rod 2002, a pulling rod 23 is rotatably mounted on the abutment plate 22, and one end of the pulling rod 23 away from the abutment plate 22 is rotatably connected to the link plate 24;

[0070] A third spring 21 is also connected to the abutment plate 22 , and one end of the third spring 21 away from the abutment plate 22 is connected to a pulling member 34 disposed on the transverse plate 18 .

[0071] When the engaging wheel 15 moves along the No. 1 horizontal groove 1103, the groove wheel 16 and the abutting wheel 17 will move horizontally with the engaging wheel 15. At this time, the groove wheel 16 can move in the No. 1 engaging groove 1801, so that the height of the lifting plate 27 remains unchanged, and the abutting wheel 17 can move toward the abutting plate 22. As the engaging wheel 15 moves, the abutting wheel 17 will abut against the abutting plate 22 and drive the abutting plate 22 to move toward the side plate 20. At this time, the abutting plate 22 can move along the length direction of the guide rod 2002, stretching the No. 3 spring 21 while making the two clamping plates 26 move away from each other. After the engaging wheel 15 moves to the end of the No. 1 horizontal groove 1103, the distance between the two clamping plates 26 reaches the maximum value (this distance is greater than the distance between the two clamping surfaces of the material), and then the engaging wheel 15 will move along the No. 2 vertical groove 1102 Movement, at this time the groove wheel 16 and the abutment wheel 17 will follow the engaging wheel 15 to move downward, during this process, the abutment wheel 17 maintains abutment with the abutment plate 22 to keep the two clamping plates 26 away from each other, and the groove wheel 16 will drive the lifting plate 27 to move downward through the transverse plate 18 and the connecting frame 19, then, the engaging wheel 15 will move along the second horizontal groove 1104 again, at this time the No. 3 spring 21 can release elastic potential energy, and drive the two clamping plates 26 to move closer to each other to clamp the material, and at the same time the groove wheel 16 moves in the opposite direction in the No. 1 engaging groove 1801 to keep the height of the lifting plate 27 unchanged, then, the engaging wheel 15 moves along the No. 1 vertical groove 1101, at this time the groove wheel 16 will drive the lifting plate 27 to move downward through the transverse plate 18 and the connecting frame 19, so that the material clamped by the clamping plate 26 can be lifted upward.

[0072] In this embodiment, the material is clamped by the elastic force provided by the No. 3 spring 21. Compared with the clamping method using a cylinder, hydraulic cylinder or other driving method in the prior art, it can effectively avoid the phenomenon that the material is compressed and deformed or cannot be stably clamped due to the influence of the stroke accuracy of the cylinder, hydraulic cylinder, etc.

[0073] Furthermore, in the present embodiment, the clamping, lifting and releasing of materials can be achieved only by a single electric telescopic rod 10, which reduces the number of driving sources used. On the one hand, it can reduce the production and use costs of the device, and on the other hand, it can improve the stability of the device operation through mechanical coordination, and avoid the occasional disorder of the action sequence caused by the use of a driver to control multiple driving sources, so that the transfer process can be carried out stably and orderly.

[0074] See also Figure 1 to Figure 6 , a mechanically actively triggered double conveyor belt transfer device, also includes: a crossbeam 1, a deflection component and a pressure component.

[0075] The cross beam 1 is provided with a transverse member 3, the transverse member 3 is connected to a linear drive module 2 provided on the cross beam 1, and the transverse member 3 is rotationally connected to the rotating shaft 4;

[0076] The deflection assembly is disposed between the transverse member 3 and the cross beam 1, and the deflection assembly can rotate the rotation shaft 4 180° when the transverse member 3 moves along the length direction of the cross beam 1;

[0077] The deflection assembly includes a gear 5 coaxially fixedly connected to the rotating shaft 4 and a rack plate 35 arranged on the crossbeam 1, and the rack plate 35 is adapted to the gear 5;

[0078] The deflection assembly further comprises a follower shaft 9 coaxially fixedly connected with the rotating shaft 4, a limiting sleeve 6 is slidably sleeved on the follower shaft 9, the limiting sleeve 6 and the follower shaft 9 are connected via a limiting structure, the limiting structure comprises a convex shaft 601 arranged on the inner wall of the limiting sleeve 6 and a convex ring arranged on the follower shaft 9, and two limiting grooves 901 are equidistantly arranged on the circumference of the convex ring;

[0079] The limiting sleeve 6 is connected to a connecting shaft 7 that passes through the transverse member 3 and is slidably arranged. A No. 1 spring 8 is sleeved on the connecting shaft 7. One end of the No. 1 spring 8 is connected to the transverse member 3, and the other end is connected to the end of the connecting shaft 7.

[0080] When in use, the beam 1 is located between two conveyor belts. After completing the clamping of the material, the linear drive module 2 can drive the transverse member 3 to move along the length direction of the beam 1, and when the transverse member 3 moves to the middle of the beam 1, the gear 5 on the rotating shaft 4 can engage with the rack plate 35 on the beam 1, so that the gear 5 can drive the rotating shaft 4 to rotate, wherein the gear 5 can rotate 180°, so that the material is switched from the side away from the movement direction of the transverse member 3 to the side of the movement direction of the transverse member 3, so that when the transverse member 3 moves to the end of the stroke, the material can be at a predetermined position on the other conveyor belt. Based on this setting, the span of the beam 1 can be reduced. On the one hand, physical deformation of the beam 1 is avoided when the transverse member 3 carries the material to move horizontally, and metal fatigue of the beam 1 is prevented. On the other hand, the space occupancy rate of the device is reduced, so that the device can be used in a relatively small space.

[0081] It is worth noting that when the rotating shaft 4 rotates, the follower shaft 9 will also rotate accordingly, and in the initial state, the cam 601 is in the limiting groove 901, so that when the follower shaft 9 rotates, the cam 601 can be disengaged from the limiting groove 901, and when the rotating shaft 4 and the follower shaft 9 rotate 180°, the cam 601 can engage with another limiting groove 901, thereby avoiding the gear 5 from continuing to rotate due to inertia after rotating 180°, thereby improving the position accuracy of the material after the orientation of the material relative to the rotating shaft 4 changes, so that the material can accurately fall on the predetermined position of the conveyor belt.

[0082] See also Figure 1~Figure 3 , Figure 5 , Figure 6 The pressure component is disposed on the rotating shaft 4 and connected to the pulling member 34. The pressure component can move the pulling member 34 away from the side plate 20 before the traverse member 3 moves and the rotating shaft 4 rotates;

[0083] The transverse plate 18 is also provided with a second fitting groove 1802, and the pulling member 34 is slidably disposed in the second fitting groove 1802;

[0084] The pressure-applying assembly includes a hysteresis groove 401 formed on the rotating shaft 4, a follower sleeve 30 and a pressing sleeve 31 are slidably installed in the hysteresis groove 401, a triangular piece 29 is connected to the follower sleeve 30, the triangular piece 29 abuts against the abutting shaft 28 connected to the pulling member 34, and a vertical shaft is provided on the pressing sleeve 31 to penetrate the transverse member 3 and slide therein;

[0085] The pressure-applying assembly further includes a trigger structure connected to the pressing sleeve 31;

[0086] The trigger structure includes a roller 32 rotatably connected to the pressing sleeve 31 and a trapezoidal member 33 disposed on the crossbeam 1 . The roller 32 cooperates with the trapezoidal member 33 to enable the pressing sleeve 31 to drive the follower sleeve 30 to move away from the transverse member 3 .

[0087] When the material to be transferred is a packaging box, excessive clamping force may cause its deformation, and excessive clamping force over a long period of time may cause permanent deformation. Taking this into consideration, in this embodiment:

[0088] In the initial state, the triangular member 29 is in contact with the abutment shaft 28, and when the material is transported, the transverse member 3 will drive the rotating shaft 4 to move transversely, and the material will follow the movement. Before the gear 5 is meshed with the rack plate 35, the roller 32 abuts against the side of the trapezoidal member 33, and then the roller 32 will drive the pressing sleeve 31 to move downward, acting on the follower sleeve 30, so that the follower sleeve 30 moves downward. At this time, the triangular member 29 will also move downward. At this time, the side of the triangular member 29 can be used to drive the abutment shaft 28 away from the rotating shaft 4, thereby driving the pulling member 34 to move away from the rotating shaft 4 along the length direction of the second interlocking groove 1802, so that The No. 3 spring 21 is further stretched, and the force of the abutment plate 22 pulled by the No. 3 spring 21 increases, which increases the force of the two clamping plates 26 acting on the material clamping surface, that is, the clamping force of the clamping plate 26 on the material is increased, so as to avoid the centrifugal force generated when the material makes a circular motion to switch the orientation, causing the material and the clamping plate 26 to separate, further improving the stability during the transportation process, and when the material completes the orientation switching, the clamping force of the two clamping plates 26 will return to the initial state, thereby avoiding the deformation of the material (packaging box) under the action of a long-term large clamping force, and reducing the damage to the material structure during the transportation process.

[0089] As an embodiment of the present invention, a method for using the mechanically actively triggered dual conveyor belt transfer device is also proposed, comprising the following steps:

[0090] Step 1: When the material moves to a predetermined position on one of the conveyor belts, the electric telescopic rod 10 starts to move, so that the engaging wheel 15 can move along the first horizontal groove 1103, the second vertical groove 1102, the second horizontal groove 1104 and the first vertical groove 1101 under the action of the switching structure;

[0091] Step 2: When the engaging wheel 15 moves along the first horizontal groove 1103, the abutting wheel 17 can abut against the abutting plate 22, and drive the two clamping plates 26 to move away from each other. When the engaging wheel 15 moves along the second vertical groove 1102, the two clamping plates 26 remain away from each other and move downward at the same time. When the engaging wheel 15 moves along the second horizontal groove 1104, the two clamping plates 26 move toward each other to clamp the material. When the engaging wheel 15 moves along the first vertical groove 1101, the two clamping plates 26 can lift the material.

[0092] Step 3: The linear drive module 2 drives the transverse member 3 to move along the length direction of the beam 1, and under the action of the pressure component, the third spring 21 is further stretched to increase the clamping force between the two clamping plates 26;

[0093] Step 4: The traverse member 3 continues to move, and then under the action of the deflection assembly, the rotation axis 4 rotates 180°;

[0094] Step 5: When the material moves to a predetermined position on another conveyor belt, the electric telescopic rod 10 moves again, so that the engaging wheel 15 can move along the first horizontal groove 1103, so that the two clamping plates 26 move away from each other, and the material is slowly released.

[0095] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
