Description

Technical Field

[0001] The present invention particularly relates to a conveying and transferring structure, method, product balanced conveying system and product production line, belonging to the technical field of product conveying and transferring. Background Art

[0002] In the production lines of some cylindrical products, it is often necessary to add a conveying line between different process main equipment, and this conveying line has the function of balancing the rotation speeds of the front and rear different process main equipment and the buffer area. At the same time, this conveying line needs to meet the requirements such as no surface scratches on the product, high production line speed, and large production line buffer capacity. However, most current production line conveying equipment often cannot meet these requirements simultaneously.

[0003] The balancer disclosed in CN 114408540A can solve the above problems, but because it uses magnetic adsorption, this method can only be used for steel products. CN 115285615A discloses a balancer conveying system using pin suspension, but this method requires a complex upper and lower pin mechanism handover, and a large amount of negative pressure air is required during the handover, resulting in high noise and energy consumption; in addition, this method is only applicable to hollow products. Therefore, it is necessary to design a new conveying system to meet the above requirements. Summary of the Invention

[0005] To achieve the foregoing invention object, the technical solutions adopted by the present invention include:

[0009] In the product transfer section of the conveying and transferring structure, a part of the second transmission mechanism is arranged between the first transmission mechanism and the third transmission mechanism along the direction of gravity. The distance between the third transmission mechanism and the second transmission mechanism gradually decreases along the direction approaching the end of the product transfer section. Both the third transmission mechanism and the second transmission mechanism operate along the direction approaching the end of the product transfer section. During the process that the pushing mechanism approaches the end of the product transfer section, the pushing mechanism has a translational displacement along the operating direction of the second transmission mechanism and a jacking displacement towards the first transmission mechanism. The product located on a second carrier is gradually jacked up by the pushing mechanism and taken away from the second carrier, and is jacked up by the pushing mechanism onto a first carrier.

[0023] Further, the clamping arm has a clamping surface facing the clamping space. The clamping surface includes a first flat section, an arc section, a second flat section, and a third flat section arranged in sequence. The first flat section and the second flat section are on the same side of the arc section. Both the first flat section and the second flat section are inclined planes tending towards the arc section. The second flat section and the third flat section are arranged at an angle. An entrance of the clamping structure is formed between the arc sections of the two clamping arms. The clamping space is located between the second flat sections and the third flat sections of the two clamping arms. The first flat section forms a guiding surface for guiding the product into the clamping space.

[0024] Further, the second carrier includes a carrier plate part and a baffle part. The baffle part is cross-fixed on the carrier plate part. The baffle part and the carrier plate part enclose an open limiting structure.

[0025] Further, the second carrier is an overall L-shaped structure.

[0029] Place the product on the second carrier, and the second transfer mechanism transfers the product to the product transfer section. In the product transfer section, while the pusher mechanism generates a translational displacement along the running direction of the second transfer mechanism together with the third transfer mechanism, it also generates a lifting displacement towards the first transfer mechanism.

[0051] In view of the deficiencies in the prior art, the inventors of this case have proposed the technical solution of the present invention through long-term research and a large number of practices. The following will further explain the technical solution, its implementation process and principle in combination with the accompanying drawings and specific embodiments. Unless otherwise specified, the conveyor belts / synchronous belts, drive chains (chains), sprockets, belt pulleys, motors / cylinders, etc. involved in the embodiments of the present invention are all known in the art. The configuration structures / methods between the conveyor belts / synchronous belts and the belt pulleys, and the drive configuration structures / methods between the drive chains (chains) and the sprockets are also known in the art, and will not be specifically limited herein.

[0052] In a more specific implementation manner, please refer to Figure 1 , a product production line includes a product balance conveying system, a first process equipment 001, and a second process equipment 004. The product balance conveying system is located between the first process equipment 001 and the second process equipment 004. The product balance conveying system is used to convey products from the first process equipment 001 to the second process equipment 004, and to cache products.

[0053] Specifically, the first process equipment 001 can be a product processing and forming process equipment, or a process equipment for polishing and other post-processing or inspection of products. The second process equipment 004 can be a process equipment for polishing, inspecting or packaging products. The first process equipment 001 and the second process equipment 004 are all known equipment in the art, and they are not the improvements of the present invention. Therefore, the specific equipment structures and models thereof will not be limited herein.

[0054] Specifically, please refer to again Figure 1, the product balanced conveying system includes an in-plant synchronous conveying balancer 003, an upper balancer assembly 002, and a lower balancer assembly 005. The upper balancer assembly 002 and the lower balancer assembly 005 are respectively arranged at the upstream end and the downstream end of the in-plant synchronous conveying balancer 003. The in-plant synchronous conveying balancer 003 includes a product conveying line and a balancer auxiliary assembly (for the specific structure of the in-plant synchronous conveying balancer 003, reference can be made to the in-plant synchronous conveying balancer 003 in CN114408540A). The upper balancer assembly 002 is used to transfer the product output from the first process equipment 001 to the product conveying line of the in-plant synchronous conveying balancer 003, and the lower balancer assembly 005 is used to unload the product from the product conveying line of the in-plant synchronous conveying balancer 003. The product unloaded by the lower balancer assembly 005 can enter the second process equipment 004.

[0055] Specifically, the product conveying line includes a balancer chain 201 and a plurality of first carriers 204. The first carriers 204 can be assembled on the balancer chain 201 through structures / methods known in the art and can move synchronously with the balancer chain 201. The first carriers 204 can detachably carry the product. Specifically, the balancer chain 201 is a closed-loop transmission mechanism to achieve continuous cyclic operation between the first process equipment 001 and the second process equipment 004 and realize the cyclic transfer of the first carriers 204 between the first process equipment 001 and the second process equipment 004.

[0056] Of course, the product conveying line also includes balancer sprockets 205, tension wheels and other auxiliary components that cooperate to realize the operation of the balancer chain 201, which are all known in the art. The balancer chain 201 is in transmission cooperation with a plurality of balancer sprockets 205. At least one of the plurality of balancer sprockets 205 is used as a driving sprocket and is directly connected to the balancer driving mechanism, and the remaining balancer sprockets 205 are used as driven sprockets, and the driven sprockets are also in transmission cooperation with the balancer chain 201. In the product conveying line of the embodiment of the present invention, except that the structure of the first carrier 204 is different from the structure of the product fixing mechanism of the in-plant synchronous conveying balancer 003 in CN114408540A, the remaining structural components can be the same or similar. It should be noted that the structure and method of fixing the first carrier 204 on the balancer chain 201 can adopt any method and structure known in the art, as long as it can keep the first carrier 204 moving with the balancer chain 201 on the balancer chain 201 and does not affect the transfer of the product between the upper balancer assembly 002 and the product conveying line. It should be noted that the balancer chain 201 can also be a conveyor belt / synchronous belt, etc.

[0057] Specifically, the upper balancer assembly 002 includes a first product transfer device. The first product transfer device includes a discharge chain 210, a plurality of second carriers 211, a pusher chain 206, and a plurality of pusher mechanisms 207. The plurality of second carriers 211 are fixedly assembled on the discharge chain 210 by a method / structure known in the art and move synchronously with the discharge chain 210. The plurality of pusher mechanisms 207 are assembled on the pusher chain 206 by a method / structure known in the art and move synchronously with the pusher chain 206. Specifically, both the discharge chain 210 and the pusher chain 206 are closed-loop transmission mechanisms, and the discharge chain 210 is distributed around the periphery of the pusher chain 206.

[0058] Of course, the first product transfer device further includes auxiliary components such as a discharge sprocket and a tensioning wheel that are in transmission cooperation with the discharge chain 210 to realize the operation of the discharge chain 210, and auxiliary components such as a pusher sprocket 209 and a tensioning wheel that are in transmission cooperation with the pusher chain 206 to realize the operation of the pusher chain 206. The discharge chain 210 is in transmission cooperation with a plurality of discharge sprockets, and at least one of the plurality of discharge sprockets is directly connected to the discharge drive mechanism as a driving wheel, and the remaining discharge sprockets are driven wheels and are also in transmission cooperation with the discharge chain 210. The pusher chain 206 is in transmission cooperation with a plurality of pusher sprockets 209, and at least one of the plurality of pusher sprockets 209 is directly connected to the pusher drive mechanism as a driving wheel, and the remaining pusher sprockets 209 are driven wheels and are also in transmission cooperation with the pusher chain 206. All of these are known in the art. Exemplarily, both the discharge drive mechanism and the pusher drive mechanism can be a rotary drive motor or the like.

[0059] It should be noted that the present invention preferably uses the balancer chain 201 as the first transmission mechanism, the discharge chain 210 as the second transmission mechanism, and the pusher chain 206 as the third transmission mechanism. Of course, the first transmission mechanism, the second transmission mechanism, the third transmission mechanism, etc. can also be replaced with a conveyor belt or a timing belt.

[0060] Specifically, please refer to Figure 1 、 Figure 2 and Figure 3, the upstream section of the product balanced conveying system close to the first process equipment 001 serves as the upstream product transfer section, and the upper balancer assembly 002 is arranged on the upstream product transfer section. In the upstream product transfer section, the product can be transferred from the second carrier 211 on the discharge chain 210 to the first carrier 204 on the balancer chain 201 by the pusher mechanism 207. More specifically, in order to realize the transfer of the product during transportation, in this upstream product transfer section, the discharge chain 210 is arranged between the pusher chain 206 and the balancer chain 201 along the gravity direction. The discharge chain 210 is parallel to the balancer chain 201 and runs in the same direction. The overall running direction of the pusher chain 206 is the same as that of the discharge chain 210 (here the overall same is relative to the opposite running direction). The pusher chain 206 is inclined towards the discharge chain 210 along the running direction of the discharge chain 210, that is, the distance between the discharge chain 210 and the pusher chain 206 gradually decreases along the running direction of the discharge chain 210. When the product on the second carrier 211 passes through the upstream product transfer section, the pusher mechanism 207 moving with the pusher chain 206 can push the product on the second carrier 211 onto the first carrier 204 on the balancer chain 201, thereby realizing the transfer of the product during the conveying process of the product.

[0061] Specifically, in the upstream product transfer section, the distance between the pusher chain 206 and the discharge chain 210 gradually decreases along the direction of the end of the upstream product transfer section (the end of the upstream product transfer section is taken as the reference standard by the running direction of the pusher chain 206 / discharge chain 210 or the running direction of the product). The balancer chain 201, the pusher chain 206, and the discharge chain 210 all run along the direction towards the end of the upstream product transfer section. Correspondingly, in the upstream product transfer section, the first carrier 204, the second carrier 211, and the pusher mechanism 207 also move along the direction towards the end of the upstream product transfer section with the balancer chain 201, the discharge chain 210, and the pusher chain 206 respectively. Moreover, since the balancer chain 201 is parallel to the discharge chain 210 and the pusher chain 206 is inclined towards the discharge chain 210, during the process of the pusher mechanism 207 approaching the end of the upstream product transfer section, the pusher mechanism 207 has a translational displacement along the running direction of the pusher chain 206 and a jacking displacement towards the balancer chain 201. Therefore, while the pusher mechanism 207 moves synchronously with the discharge chain 210, it also moves upwards along the gravity direction towards the balancer chain 201, and takes the product away from the second carrier 211 and pushes it into the first carrier 204 on the balancer chain 201. Specifically, in the upstream product transfer section, each pusher mechanism 207 corresponds to a second carrier 211 and a first carrier 204 one by one. A second carrier 211 and a first carrier 204 are both located on the jacking displacement track of the pusher mechanism 207 and move synchronously in the running direction of the discharge chain 210, thereby realizing the continuous conveying and transfer of the product.

[0062] For details, please refer to Figure 2 In order to realize the synchronous movement of the pushing mechanism 207 and the second carrier 211, the pushing chain 206 and the discharging chain 210 are preferably connected by a transmission structure, and the discharging drive mechanism and the pushing drive mechanism that drive the pushing chain 206 and the discharging chain 210 are the same. Specifically, the transmission structure can be a synchronous chain 208, and the synchronous chain 208 is respectively connected by transmission with at least one pushing sprocket 209 directly matched with the pushing chain 206 and at least one discharging sprocket directly matched with the discharging chain 210.

[0063] Specifically, in order to better cooperate with the transfer of products in the upstream product transfer section, the first carrier 204 adopts a clamping structure to receive and fix the product, and the entrance 305 of the clamping structure is opposite to the balancer chain 201. In the upstream product transfer section, the entrance 305 of the clamping structure faces the discharge chain 210. The side of the second carrier 211 opposite to the discharge chain 210 is a bearing surface for bearing the product. The bearing surface only has a limiting effect on the product to limit the translation of the product along the bearing surface. The second carrier 211 has no restriction on the movement of the product in the direction perpendicular to the bearing surface. Through such a design, in pushing the material As the mechanism 207 moves with the pushing chain 206, the pushing mechanism 207 moves upward and approaches the balancer chain 201. The pushing mechanism 207 first contacts the product on the second carrier 211 from the bottom of the product. As the pushing mechanism 207 continues to move, the product is pushed upward from the second carrier 211 by the pushing mechanism 207 and taken away from the second carrier 211. Afterwards, as the product is pushed up by the pushing mechanism 207 and begins to contact the clamping structure of the first carrier 204, it is stuck into the clamping structure from the entrance 305 of the clamping structure and is captured and fixed by the clamping structure, thereby realizing the transfer of the product.

[0064] For details, please refer to Figure 4, the clamping structure can clamp the product separably. The width of the inlet 305 of the clamping structure < the maximum width of the product < the maximum width of the internal clamping space of the clamping structure. The width of the inlet 305 of the clamping structure can undergo recoverable changes under the action of external extrusion. It can be understood that the product enters the clamping structure under the extrusion of the pushing mechanism 207 and the first carrier 204 when it is in contact with the pushing mechanism 207 and the first carrier 204 simultaneously. Specifically, in order to realize the change of the size of the inlet 305 of the clamping structure, the clamping structure is preferably a flexible clamping structure. More specifically, the clamping structure includes two clamping arms (which can also be called clamping claws). One end of the two clamping arms is connected, and the other end is separated. A clamping space is formed between the two clamping arms. An inlet 305 of the clamping structure is formed between the separated ends of the two clamping arms. At least one clamping arm is a flexible structure. More specifically, the clamping arm has a clamping surface facing the clamping space. The clamping surface includes a first flat section 301, an arc section 302, a second flat section 303, and a third flat section 304 arranged in sequence. The first flat section 301 and the second flat section 303 are on the same side of the arc section 302. Both the first flat section 301 and the second flat section 303 are inclined planes tending to the arc section 302. The second flat section 303 and the third flat section 304 are arranged at an angle. An inlet 305 of the clamping structure is formed between the arc sections 302 of the two clamping arms. The clamping space is located between the second flat sections 303 and the third flat sections 304 of the two clamping arms. The first flat section 301 forms a guiding surface for guiding the product into the clamping space. When the product 203 enters the clamping structure by more than half, it can automatically enter the clamping structure to complete the handover.

[0065] It should be noted that, in order to reduce the wear on the surface of the product when the first carrier contacts the product, the part of the clamping structure of the first carrier in contact with the product is a smooth structure and / or a flexible structure, such as a silica gel layer, etc.

[0066] Specifically, the second carrier 211 includes a carrier plate part and a baffle part. The baffle part is cross-fixed on the carrier plate part. The baffle part and the carrier plate part enclose an open limiting structure. The second carrier 211 is an L-shaped structure as a whole. More specifically, in order to facilitate the transfer of the product, there is no direct fixing relationship between the second carrier 211 and the product. Please refer to Figure 1 and Figure 3 , in the upstream product transfer section, the balancer chain 201 and the discharge chain 210 are arranged to be inclined upward along their own running directions. The baffle part of each second carrier 211 is arranged on the side opposite to its own running direction of the carrier plate part. Thus, the product can be prevented from falling off the second carrier 211.

[0067] It should be noted that, in order to reduce the wear on the surface of the product when the second carrier contacts the product, the surface of the part of the second carrier in contact with the product is a smooth structure and / or a flexible structure, such as a silica gel layer, etc.

[0068] For details, please refer to Figure 2 The pushing mechanism 207 includes two pushing heads, which are arranged at intervals along the width direction of the pushing chain 206. In the upstream product transfer section, the two pushing heads included in each pushing mechanism 207 are arranged at intervals on both sides of the second carrier 211 and the first carrier 204, thereby improving the stability of the pushing mechanism 207 in supporting the product when lifting the product, preventing the product from falling, and at the same time ensuring that the product can be stably received by the first carrier 204. It should be noted that in order to reduce the wear of the product surface caused by the pushing mechanism 207 when contacting the product, the surface of the pushing mechanism 207 that contacts the product is a smooth structure and / or a flexible structure, such as a silicone layer.

[0069] For details, please refer to Figure 1 , Figure 2 and Figure 5 The downstream section of the product balance conveying system close to the second process equipment 004 is used as the downstream product transfer section, and the lower balancer assembly 005 is arranged in the downstream product transfer section. In the downstream product transfer section, the lower balancer assembly 005 can unload the product from the first carrier 204 of the balancer chain 201. Specifically, the lower balancer assembly 005 includes a second product transfer device, and the second product transfer device includes a discharge drive mechanism 502 and a discharge mechanism 501. The discharge mechanism 501 is connected to the discharge drive mechanism 502 in a transmission manner and can reciprocate along a selected trajectory under the discharge drive mechanism 502. In addition, the selected trajectory intersects with the running trajectory of the discharge chain 210 / product. The discharge mechanism 501 can contact the product at the intersection with the running trajectory of the discharge chain 210 / product and make the product separate from the first carrier 204. Specifically, the unloading mechanism 501 includes two unloading blocks that are spaced apart and arranged in parallel, and the top of the unloading block is a hook-shaped structure. When the unloading block is driven to move downward, the hook-shaped structure of the unloading block will contact the product on the first carrier 204 and drive the product to move downward together, so that the product can be released from the clamping structure of the first carrier 204. The product separated from the first carrier 204 can fall to the second process equipment 004 under the action of its own gravity. Of course, additional functional mechanisms can also be set to receive the product separated from the first carrier 204.

[0070] It should be noted that the product can be a cylindrical product, or of course, a product of other shapes. For example, the product can also be a battery shell or a can or other products.

[0071] Please also read Figure 1 , Figure 2, the product is output from the self-produced product 006 of the first process equipment 001 and is received by the second carrier 211. The product is conveyed backward along with the discharge chain 210. When the second carrier 211 carrying the product 203 runs to the upstream product transfer section, the pusher mechanism 207 moves downstream synchronously with the second carrier 211. At the same time, the pusher mechanism 207 also gradually moves upward and approaches the second carrier 211 until the pusher mechanism 207 lifts the product on the second carrier 211 and takes it away from the second carrier 211. At this time, the first carrier 204 on the balancer chain 201 has moved downstream along with the second carrier 211 and the pusher mechanism 207. The pusher mechanism 207 moves upward and pushes the product into the clamping structure of the first carrier 204 and is fixed by the first carrier 204. At this time, the transfer of the product between the second carrier 211 and the first carrier 204 is completed. The second carrier 211, the first carrier 204, and the pusher mechanism 207 that cooperate to complete the product transfer run to the end of the upstream product transfer section or are about to run to the end of the upstream product transfer section. Subsequently, the pusher mechanism 207 gradually disengages from the product 203 and starts to move back upstream. The product 203 fixed by the first carrier 204 continues to move downstream. After passing through the in-equipment synchronous conveying balancer 003 and being output from the in-equipment synchronous conveying balancer 003, it reaches the downstream section near the second process equipment 004. In the downstream product transfer section, the product on the first carrier 204 is unloaded by the second product transfer device, the empty first carrier 204 moves upstream, and the unloaded product enters the second process equipment 004 from the product inlet 007.
