Description

Technical Field

[0001] The invention relates to the field of conveying devices, in particular to an accumulation roller conveying device. Background Art

[0002] The accumulation roller conveyor is a conveying device that can stop the goods at the workstation through a blocker without stopping the driving device. It uses the rotation of the roller and the friction between the roller and the workpiece to realize the transmission of the workpiece, and has the function of accumulating goods at a specific position. The working principle of the accumulation roller conveyor is to control the running resistance torque to exceed or be lower than the specified working torque through friction conversion, so as to realize the accumulation function. When the goods reach the specified position, the blocker will act on the goods to stop them from moving forward, while the conveying wheel continues to rotate but no longer pushes the goods. In this way, the goods can be accumulated at the work station and wait for the next step of processing.

[0003] In the prior art, when the blocker acts on the goods, causing them to stop moving, if the conveying wheel continues to rotate, it will generate unnecessary friction with the placement plate carrying the goods.

DETAILED DESCRIPTION

[0016] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] For example, see Figure 1 - Fig. 9 The present invention provides a technical solution for an accumulating roller conveyor device: the accumulating roller conveyor device comprises: a conveying frame 1, a motor 11 is fixedly connected to one side of the inner wall of the conveying frame 1, a driving wheel 16 is fixedly connected to the output end of the motor 11, a synchronous shaft 12 is rotatably connected to both sides of the inner wall of the conveying frame 1, and a conveying mechanism is fixedly connected to the outer walls at both ends of the synchronous shaft 12.

[0018] When the driven wheel 18 drives the synchronous shaft 12 to rotate, the synchronous shaft 12 can drive the two conveying mechanisms to move at the same time, avoiding the conveying frame 1 from being out of sync when conveying objects, correspondingly reducing the tilting of objects during the conveying process, and ensuring the stability of the objects during the conveying process.

[0019] Embodiment 2, on the basis of embodiment 1, a transmission mechanism includes a second pulley 15, the inner walls of the axes of the two second pulleys 15 are fixedly connected to the two ends of the outer wall of the synchronous shaft 12, the outer wall of one end of the synchronous shaft 12 is fixedly connected to a driven wheel 18 near the outer wall of the second pulley 15, the outer wall of the driven wheel 18 is rotatably connected to a first belt 17, one end of the inner ring wall of the first belt 17 is rotatably connected to the outer wall of the driving wheel 16, the upper part of the inner wall of the conveying frame 1 is rotatably connected to pulleys 13, the outer wall of the pulley 13 is rotatably connected to a conveyor belt 14, and the inner ring walls of the two conveyor belts 14 are rotatably connected to the outer wall of the second pulley 15.

[0020] By setting the pulley 13, it is avoided that the conveyor belt 14 forms a three-star shape only through the cooperation of the pulley 2 15 and the driving wheel 4 when moving back, thereby optimizing the movement trajectory of the conveyor belt 14. Correspondingly, the setting of the pulley 13 not only limits the movement trajectory of the conveyor belt 14, but also enables the conveyor belt 14 to move horizontally under the driving wheel 4, thereby reducing the space occupied by the conveyor belt 14 on the conveying frame 1, making the entire conveying system more compact and efficient, and further increasing the smoothness and beauty of the movement trajectory of the conveyor belt 14 on the conveying frame 1.

[0021] Embodiment three, on the basis of embodiment two, circular holes are opened on both sides of the inner wall of the conveying frame 1, a plurality of circular holes are fixedly connected with a rotating shaft 51 inside, the outer wall of the rotating shaft 51 is rotatably connected with a driving wheel 4, the outer walls of the plurality of driving wheels 4 are rotatably connected with the inner ring wall of the conveyor belt 14, the outer wall of one side of the driving wheel 4 is fixedly connected with a connecting sleeve 41, the outer wall of the connecting sleeve 41 is rotatably connected with a conveying wheel 2, the outer wall of the connecting sleeve 41 is fixedly connected with an anti-skid pad 2 42, an axial hole is opened on the conveying wheel 2, the inner wall of the axial hole is fixedly connected with an anti-skid pad 1 22, the inner ring wall of the anti-skid pad 1 22 is in movably contact with the outer ring wall of the anti-skid pad 2 42.

[0022] By setting the anti-skid pad 2 42 on the connecting sleeve 41 and the anti-skid pad 1 22 on the transmission wheel 2, the friction between the transmission wheel 2 and the connecting sleeve 41 is further increased, and the friction is then used to ensure that the transmission wheel 2 can be driven to rotate when the driving wheel 4 rotates, and then the contact between the transmission wheel 2 and the placement plate 3 is used to push the placement plate 3 when the transmission wheel 2 rotates, so that the placement plate 3 drives the objects to be transported to the end point, and the transmission of the objects is completed. The material of the transmission wheel 2 is polyurethane, which has good properties such as strong wear resistance, chemical corrosion resistance, high strength, high elasticity, low pressure resistance, strong shock absorption, tear resistance, radiation resistance, high load-bearing and shock absorption, avoiding the shortcomings of conventional chains and belts that will fall off powder and chips after long-term use, and correspondingly solves the extremely high requirements of the medical industry and the semiconductor industry on the cleanliness of objects, thereby improving product quality and qualified rate.

[0023] Embodiment 4, on the basis of embodiment 3, the outer wall of the transmission wheel 2 is fixedly connected with a plurality of limit rods 2 31, the outer wall at the top of the transmission wheel 2 is in interactive contact with the placement plate 3, the outer wall at the bottom of the placement plate 3 is fixedly connected with a plurality of limit rods 2 31, and the outer wall of the limit rod 2 31 is in movably contact with the outer wall of the limit rod 1 21.

[0024] By limiting the limit rod 1 21 by the limit rod 2 31, the state in which the conveying wheel 2 continues to move with the connecting sleeve 41 can be stopped, thereby avoiding the friction on the placement plate 3 caused by the conveying wheel 2 continuing to move with the connecting sleeve 41 when the placement plate 3 stops. Such friction will not only wear the surface of the placement plate 3, but also accelerate the loss of the conveying wheel 2. Accordingly, when the placement plate 3 stops moving, the conveying wheel 2 also stops moving, thereby reducing the friction between the conveying items and the conveying wheel 2, ensuring that the product does not drop powder or chips, and improving the integrity and quality of the product.

[0025] Embodiment 5, on the basis of embodiment 4, a square groove 53 is provided inside the rotating shaft 51, an outer wall at one end of the rotating shaft 51 is fixedly connected with an elastic pad 52, and limiting grooves 511 are provided on both upper and lower sides of the inner wall of the square groove 53, an outer wall at one end of the elastic pad 52 is movably contacted with a baffle 5, an outer wall on one side of the baffle 5 is fixedly connected with a memory elastic plate 58, and an outer wall on the opposite side of the two memory elastic plates 58 is fixedly connected with a limiting block 510, and the outer wall of the limiting block 510 is movably plugged into the inner part of the limiting groove 511, and one side of the baffle 5 is fixedly connected with a memory elastic plate 58. The outer wall of the rotating shaft 51 is fixedly connected with a push rod 59, and a cylindrical groove 54 is opened at one end of the inner part of the rotating shaft 51 near the square groove 53. A return spring 55 is fixedly connected to the inner wall of the cylindrical groove 54, and a mounting plate 56 is fixedly connected to the outer wall of one end of the return spring 55. A support ball 57 is fixedly connected to the outer wall of one end of the mounting plate 56. The outer wall of the support ball 57 is in active contact with the outer wall of the opposite side of the two memory elastic plates 58, and the outer wall of the mounting plate 56 is slidably connected to the inside of the cylindrical groove 54, and a rubber ring is fixedly connected to the outer wall of the mounting plate 56.

[0026] The memory elastic plate 58 is expanded by the expansion ball 57. As the expansion process proceeds, the limiting block 510 on the memory elastic plate 58 is inserted into the limiting groove 511, so that the memory elastic plate 58 can be limited, so that the baffle 5 is fixed to one end of the rotating shaft 51, and the transmission wheel 2 can be fixed to the connecting sleeve 41, thereby preventing the transmission wheel 2 from falling off from the connecting sleeve 41 during operation, and correspondingly increasing the stability of the transmission wheel 2; Through the action of the push rod 59, the expansion ball 57 will be pushed into the inside of the cylindrical groove 54, and the support of the expansion ball 57 on the memory elastic plate 58 will be released, so that the memory elastic plate 58 can return to its original position under the elasticity of the memory elastic plate 58 itself, thereby releasing the fixation of the limit block 510 on the limit groove 511, and the baffle 5 drives the memory elastic plate 58 to be taken out from the inside of the square groove 53, so that the connecting sleeve 41 on the transmission wheel 2 can be removed, which is convenient for maintenance of the transmission wheel 2 and avoids the threaded connection between the baffle 5 and the rotating shaft 51. Tools are needed when removing the baffle 5 from the rotating shaft 51, which correspondingly increases the efficiency of removing the baffle 5, and further improves the efficiency of replacing or maintaining the transmission wheel 2.

[0027] In actual use, first, start the motor 11 on the conveying frame 1 to work, and then through the movement of the motor 11, the driving wheel 16 can be driven to rotate, and through the movement of the driving wheel 16, the first belt 17 can drive the driven wheel 18 to rotate accordingly, and then the driven wheel 18 and the synchronous shaft 12 are fixedly connected. When the driven wheel 18 drives the synchronous shaft 12 to rotate, the synchronous shaft 12 can drive the two conveying mechanisms to move at the same time, avoiding the conveying frame 1 from being out of sync when conveying objects, and correspondingly reducing the inclination of objects during the conveying process, ensuring the stability of objects during the conveying process.

[0028] The rotation of the synchronous shaft 12 simultaneously drives the two pulleys 15 to rotate, which further drives the conveyor belt 14 to form a reciprocating cycle between the pulley 2 15 and the driving wheel 4, and the setting of the pulley 13 limits the movement trajectory of the conveyor belt 14, ensuring that the conveyor belt 14 runs stably and orderly between the pulley 2 15 and the driving wheel 4, avoiding the conveyor belt 14 from forming a three-star shape only through the cooperation of the pulley 2 15 and the driving wheel 4 when moving back, thereby optimizing the movement trajectory of the conveyor belt 14, and correspondingly, the setting of the pulley 13 not only limits the movement trajectory of the conveyor belt 14, but also enables the conveyor belt 14 to move horizontally under the driving wheel 4, thereby reducing the space occupied by the conveyor belt 14 on the conveying frame 1, making the entire conveying system more compact and efficient, and further increasing the smoothness and beauty of the movement trajectory of the conveyor belt 14 on the conveying frame 1.

[0029] After the accumulation roller conveyor device is started, the items can be placed on the placement plate 3. At this time, the driving wheel 4 drives the connection sleeve 41 to rotate, and the anti-skid pad 2 42 arranged on the connection sleeve 41 and the anti-skid pad 1 22 arranged on the transmission wheel 2 can further increase the friction between the transmission wheel 2 and the connection sleeve 41. Then, the friction force is used to ensure that the transmission wheel 2 can be driven to rotate when the driving wheel 4 rotates. Then, the contact between the transmission wheel 2 and the placement plate 3 is used to push the placement plate 3 when the transmission wheel 2 rotates, so that the placement plate 3 drives the items to be transported to the end point, and the transmission of the items is completed. The material of the transmission wheel 2 is polyurethane, which has good properties such as strong wear resistance, chemical corrosion resistance, high strength, high elasticity, low pressure resistance, strong shock absorption, tear resistance, radiation resistance, high load-bearing and shock absorption and buffering, which avoids the shortcomings of conventional chains and belts that will fall off powder and chips after long-term use, and correspondingly solves the extremely high requirements of the medical industry and the semiconductor industry for the cleanliness of items, thereby improving product quality and qualified rate.

[0030] When the object is conveyed to the end point and the operator applies pressure to the placement plate 3 to stop it, the limit rod 2 31 arranged at the bottom of the placement plate 3 can cooperate with the limit rod 1 21, so that the limit rod 2 31 can be inserted into the gap between the two limit rods 21 when the placement plate 3 is pressed and moves downward, thereby limiting the limit rod 1 21. By limiting the limit rod 1 21 by the limit rod 2 31, the state in which the conveying wheel 2 continues to move with the connecting sleeve 41 can be stopped, avoiding the friction of the conveying wheel 2 on the placement plate 3 when the placement plate 3 stops. This friction will not only wear the surface of the placement plate 3, but also accelerate the loss of the conveying wheel 2. Accordingly, when the placement plate 3 stops moving, the conveying wheel 2 also stops moving, thereby reducing the friction between the conveyed object and the conveying wheel 2, ensuring that the product does not drop powder or chips, and improving the integrity and quality of the product.

[0031] When the transmission wheel 2 is inserted into the connecting sleeve 41, the baffle 5 can drive the memory elastic plate 58 to be inserted into the inside of the square groove 53. When the inclined surface on the memory elastic plate 58 contacts the opening ball 57, the operator continues to push the baffle 5. Since the opening ball 57 is in the shape of a hemisphere, the memory elastic plate 58 can be opened by the opening ball 57 when the memory elastic plate 58 moves along the edge of the opening ball 57. As the opening process proceeds, the limiting block 510 on the memory elastic plate 58 is inserted into the inside of the limiting groove 511, so that the memory elastic plate 58 can be limited. Therefore, the baffle 5 is fixed to one end of the rotating shaft 51, and the transmission wheel 2 can be fixed to the connecting sleeve 41, so as to prevent the transmission wheel 2 from falling off from the connecting sleeve 41 during operation, and correspondingly increase the stability of the transmission wheel 2.

[0032] Then, through the device of the elastic pad 52, the baffle plate 5 will be pushed toward the outside of the rotating shaft 51. When the memory elastic plate 58 is driven by the baffle plate 5 to move outward inside the rotating shaft 51, the limit block 510 can be tightly fitted with one side of the inner wall of the limit groove 511, thereby ensuring the stability of the memory elastic plate 58 inside the square groove 53.

[0033] It should be noted that the length of the limiting groove 511 is greater than the length of the limiting block 510 .

[0034] The elastic pad 52 connected to one end of the rotating shaft 51 can be used to shorten the elastic pad 52 through the pressure applied by the baffle 5 to the elastic pad 52 when the operator continues to push the baffle 5. At this time, the push rod 59 will push the expansion ball 57 into the inside of the cylindrical groove 54, releasing the support of the expansion ball 57 on the memory elastic plate 58, so that the memory elastic plate 58 can return to its original position under the elasticity of the memory elastic plate 58 itself, thereby releasing the fixing of the limit block 510 to the limit groove 511, so that the baffle 5 can drive the memory elastic plate 58 to be taken out from the inside of the square groove 53, and the baffle 5 can be separated from the rotating shaft 51, The connecting sleeve 41 on the transmission wheel 2 can be removed, which is convenient for maintenance of the transmission wheel 2, and avoids the threaded connection between the baffle 5 and the rotating shaft 51. When the baffle 5 is removed from the rotating shaft 51, a tool is still needed, which correspondingly increases the efficiency of removing the baffle 5, and further improves the efficiency of replacing or maintaining the transmission wheel 2.

[0035] By setting a rubber ring on the outer wall of the mounting plate 56, the friction between the mounting plate 56 and the cylindrical groove 54 can be increased by the rubber ring, thereby slowing down the efficiency of the reset spring 55 in pushing the propeller ball 57 to return to its original position, leaving enough time for the memory elastic plate 58 to be pulled out from the square groove 53.

[0036] It should be noted that the elastic force of the return spring 55 itself is greater than the force of deformation of the memory elastic plate 58 .

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
