[0047] The present invention will now be described in further detail with reference to the accompanying drawings.

[0048] Please see Figures 1 to 3 A transfer conveying device 100 provided in this embodiment of the present utility model includes a frame 110, a first conveying mechanism 120, a second conveying mechanism 130, a first lifting mechanism 141, and a second lifting mechanism 142. The first conveying mechanism 120 is disposed on the frame 110 and is used to convey products. The second conveying mechanism 130 is disposed on the frame 110 and is used to convey products. The second conveying mechanism 130 is located above the first conveying mechanism 120, and the conveying directions of the first conveying mechanism 120 and the second conveying mechanism 130 are opposite. The first lifting mechanism 141 is disposed below the first conveying mechanism 120 and is used to lift the products conveyed by the first conveying mechanism 120 and drive the products to rotate around a vertical axis. The second lifting mechanism 142 is disposed below the second conveying mechanism 130 and is used to lift the products conveyed by the first conveying mechanism 120 and drive the products to rotate around a vertical axis.

[0049] The product includes a carrier and a workpiece placed in the carrier; or, the product can be understood as a workpiece, or the product is only a workpiece, which is not specified in detail in this application.

[0050] In practical applications, when the transfer conveyor 100 is used between two devices 200, the two ends of the first conveyor 120 are respectively connected to the return lines 230 of the two devices 200, and the two ends of the second conveyor 130 are respectively connected to the working lines 220 of the two devices 200.

[0051] In one possible conveying configuration, the workline 220 of one device 200 conveys the product to a second conveying mechanism 130. The second conveying mechanism 130 conveys the product directly above a second lifting mechanism 142, which lifts the product upward and rotates it 180 degrees around its vertical axis, thus reversing the product's orientation. Then, the second lifting mechanism 142 places the product back onto the second conveying mechanism 130, which then feeds the product into another device 200. The other device 200 switches the product from a high position to a low position and uses its return line 230 to feed the product into a first conveying mechanism 120. The first conveying mechanism 120 conveys the product directly above a first lifting mechanism 141, which lifts the product upward and rotates it 180 degrees around its vertical axis, thus reversing the product's orientation and restoring it to its previous direction. The first lifting mechanism 141 places the product back onto the first conveying mechanism 120, and the first conveying mechanism 120 re-inputs the product into the previous device 200.

[0052] As can be seen from the above, the transfer conveying device 100, through the arrangement of the first conveying mechanism 120 and the second conveying mechanism 130, can transport the product of one device 200 to another device 200. During the process of the product passing through the second conveying mechanism 130, the second lifting mechanism 142 can adjust the direction of the product, without the need for manual mechanical reversal of the product. Similarly, the first conveying mechanism 120 can return the product of the next device 200 to the previous device 200. During the process of the product passing through the first conveying mechanism 120, the first lifting mechanism 141 can adjust the direction of the product, without the need for manual reversal of the product.

[0053] Therefore, the transfer conveyor 100 of this application not only realizes the cyclical transport of items between the two devices 200, but also realizes that the direction of the product is restored to the state of transmission during the reciprocating motion, instead of relying on manual adjustment of the product's direction, thus reducing the workload of the staff and ensuring the efficiency of the two devices 200 working together.

[0054] In some embodiments, please refer to Figures 1 to 3 The first lifting mechanism 141 and the second lifting mechanism 142 adopt approximately the same structure, and therefore, they can be collectively referred to as lifting mechanism 140. Lifting mechanism 140 includes a first driving member 143, a second driving member 144, and a support platform 145. The first driving member 143 is disposed on the frame 110 and is used to provide an upward driving force; the second driving member 144 is connected to the first driving member 143 and is used to provide a circumferential rotational force about a vertical axis; the support platform 145 is connected to the second driving member 144 and is used to support the product.

[0055] The first driving component 143 can be a driving module such as a cylinder or an electric push rod, and the second driving component 144 can be a motor, a hydraulic cylinder or a pneumatic cylinder.

[0056] Specifically, when the product is conveyed above the first lifting mechanism 141 or the second lifting mechanism 142, the first driving member 143 drives the second driving member 144 and the support platform 145 to move upward, with the support platform 145 abutting against the bottom of the product. If the first driving member 143 continues to provide upward driving force, the support platform 145 lifts the product upward and separates from the conveying mechanism. When the support platform 145 moves to a sufficient height, the conveying mechanism cannot interfere with the circumferential rotation of the support platform 145. Therefore, the second driving member 144 can drive the support platform 145 to rotate 180 degrees around the vertical axis, and the support platform 145 drives the product to rotate 180 degrees, thereby realizing the product reversal. After the product reversal is completed, the first driving member 143 drives the support platform 145 to move downward, and the support platform 145 drives the product to move downward as well, until the product on the support platform 145 is placed back on the conveyor belts 1525 on both sides of the conveying mechanism.

[0057] In some embodiments, please refer to Figures 3 to 4 The transfer conveying device 100 also includes a lifting conveying mechanism 150, which includes a lifting drive module 151 and a conveying module 152 connected to each other. The lifting drive module 151 is located on one side of the frame 110, and the conveying module 152 is connected to the lifting platform of the lifting drive module 151. The lifting drive module 151 is used to drive the conveying module 152 to move vertically, so that the lifting drive module 151 can be adjusted at multiple height positions.

[0058] Specifically, when the conveying module 152 needs to be connected with the first conveying mechanism 120, the lifting drive module 151 drives the conveying module 152 to move up and down to the height of the first conveying mechanism 120. At this time, the conveying module 152 can be connected with the first conveying mechanism 120, thereby realizing the conveying of the product. When the conveying module 152 needs to be connected with the return line 230 of the external equipment, the lifting drive module 151 drives the conveying module 152 to move up and down to the height of the first conveying mechanism 120. At this time, the conveying module 152 can be connected with the return line 230 of the external equipment, thereby realizing the conveying of the product.

[0059] Furthermore, there are two lifting and conveying mechanisms 150. One lifting and conveying mechanism 150 has a conveying module 152 that is connected to the input end of the first conveying mechanism 120, and the other lifting and conveying mechanism 150 has a conveying module 152 that is connected to the output end of the first conveying mechanism 120.

[0060] It is understandable that, through the setting of the lifting and conveying mechanism 150, when the first conveying mechanism 120 is connected to the return line 230 of other equipment 200, the lifting drive module 151 adjusts the up and down position by driving the conveying module 152, so that it can be connected to the return line 230 of the external equipment 200, thereby allowing the transfer conveying device 100 to be used flexibly.

[0061] In other possible embodiments, in order to enable the first lifting conveyor 150 to be flexibly connected to the return lines 230 of the two devices 200, the first conveyor 120 is correspondingly provided with a lifting power module (not shown in the figure). The lifting power module is located on one side of the frame 110. The first conveyor 120 is connected to the lifting seat of the lifting power module. The first conveyor 120 is used for conveying products. The two ends of the first conveyor 120 are respectively connected to the return lines 230 of the two devices 200.

[0062] Understandably, when the first conveyor mechanism 120 needs to connect with the return lines 230 of the two devices 200, the lifting power module drives the first conveyor mechanism 120 to move up and down, thereby adjusting the height of the first conveyor mechanism 120. This configuration allows both ends of the first conveyor mechanism 120 to connect with the return lines 230 of the two devices 200. For example, if multiple return lines 230 are located on the lower side of the two devices 200, the lifting power module can adjust the first conveyor mechanism 120 to different heights according to actual needs, enabling the first conveyor mechanism 120 to connect with return lines 230 at different positions.

[0063] Further, please refer to Figures 4 to 5The conveying module 152 includes a mounting frame 1521, two sets of roller assemblies 1523, two conveyor belts 1525, a connecting shaft 1526, and a drive assembly 1527. The mounting frame 1521 has two opposing side plates 1522, and the two sets of roller assemblies 1523 are respectively mounted on the two side plates 1522. Each set of roller assemblies 1523 includes multiple rollers 1524 rotatably mounted on the side plate 1522, arranged sequentially along the product conveying direction. The two conveyor belts 1525 are respectively wound around the rollers 1524 of the two sets of roller assemblies 1523, and the product is placed on the two conveyor belts 1525. The connecting shaft 1526 is rotatably mounted on the two side plates 1522 of the mounting frame 1521, and one roller 1524 of each set of roller assemblies 1523 is fixed to the connecting shaft 1526. Therefore, when the rollers 1524 of a set of roller assemblies 1523 rotate, the rollers 1524 drive the rollers 1524 of another set of roller assemblies 1523 to rotate via the connecting shaft 1526. The drive assembly 1527 includes a motor, which is mounted on the frame 110 or the mounting bracket 1521. A drive wheel is provided on the drive shaft of the motor, and a transmission belt 1525 is wound around the drive wheel. Thus, the motor drives one transmission belt 1525 to move via the drive wheel. The transmission belt 1525 drives the corresponding roller assembly 1523 to rotate, and the roller assembly 1523 drives the other roller assembly 1523 to rotate, thereby driving the other transmission belt 1525 to move synchronously.

[0064] This application discloses a device line; please refer to [link / reference]. Figures 1 to 3 It includes two devices 200 and the aforementioned transfer conveyor 100, with the transfer conveyor 100 connected between the two devices 200.

[0065] In practical application, the workline 220 of one device 200 conveys the product to the second conveying mechanism 130. The second conveying mechanism 130 conveys the product directly above the second lifting mechanism 142. The second lifting mechanism 142 lifts the product upward and rotates it 180 degrees around its vertical axis, thus reversing the product's orientation. Then, the second lifting mechanism 142 places the product back onto the second conveying mechanism 130, which then inputs the product into another device 200. The other device 200 switches the product from a high position to a low position and uses its return line 230 to transfer the product into the first conveying mechanism 120. The first conveying mechanism 120 conveys the product directly above the first lifting mechanism 141. The first lifting mechanism 141 lifts the product upward and rotates it 180 degrees around its vertical axis, thus reversing the product's orientation, i.e., restoring it to its previous direction. The first lifting mechanism 141 places the product back onto the first conveying mechanism 120, which then inputs the product back into the first device 200.

[0066] As can be seen from the above, the transfer conveying device 100, through the arrangement of the first conveying mechanism 120 and the second conveying mechanism 130, can transport the product of one device 200 to another device 200. During the process of the product passing through the second conveying mechanism 130, the second lifting mechanism 142 can adjust the direction of the product, without the need for manual mechanical reversal of the product. Similarly, the first conveying mechanism 120 can return the product of the next device 200 to the previous device 200. During the process of the product passing through the first conveying mechanism 120, the first lifting mechanism 141 can adjust the direction of the product, without the need for manual reversal of the product.

[0067] Therefore, the transfer conveyor 100 of this application not only realizes the cyclical transport of items between the two devices 200, but also realizes that the direction of the product is restored to the state of transmission during the reciprocating motion, instead of relying on manual adjustment of the product's direction, thus reducing the workload of the staff and ensuring the efficiency of the two devices 200 working together.

[0068] In some embodiments, please refer to Figures 1 to 3 Each piece of equipment 200 includes a machine base 210, a working line 220, a return line 230, and a lifting conveyor line 240. The working line 220 is located on top of the machine base 210. One end of a second conveying mechanism 130 is connected to the working line 220 of one piece of equipment 200, and the other end is connected to the working line 220 of another piece of equipment 200. Thus, products from one piece of equipment 200 can be transferred to another piece of equipment 200 via the second conveying mechanism 130. The return line 230 is located inside the machine base 210, below the working line 220, and its conveying direction is opposite to that of the working line 220. One end of a first conveying mechanism 120 is connected to the return line 230 of one piece of equipment 200, and the other end is connected to the return line 230 of another piece of equipment 200. Thus, products from one piece of equipment 200 can be returned to another piece of equipment 200 via the first conveying mechanism 120. The lifting conveyor line 240 is located on the side of the machine base 210 away from the frame 110 and is used for conveying products between the working line 220 and the return line 230.

[0069] In the specific working process, after passing through one piece of equipment 200, the product is conveyed from the work line 220 of that equipment 200 and then transferred to the second conveyor mechanism 130. The second conveyor mechanism 130 then transfers the product to the work line 220 of the next piece of equipment 200. After processing at the next piece of equipment 200, the product is conveyed through the work line 220 to the corresponding lifting conveyor line 240. Upon receiving the product, the lifting conveyor line 240 moves the product to the return line 230 and transfers it to that line. Then, the return line 230 transfers the product to the first conveyor mechanism 120, which in turn transfers the product to the return line 230 of another piece of equipment 200. The return line 230 can then transfer the product to the lifting conveyor line 240 corresponding to the previous piece of equipment 200. Finally, the lifting conveyor line 240 transfers the product back to the work line 220 of the previous piece of equipment 200, thus achieving product circulation.

[0070] Furthermore, the return line 230 is provided with multiple layers, and the multiple return lines 230 are arranged sequentially along the height direction of the machine platform 210. Each layer of return line 230 can be used to store products, and the lifting conveyor line 240 can sequentially transfer the assembled products to different return lines 230, thereby achieving product pressure holding.

[0071] In order to enable the first conveying mechanism 120 to be connected to each return line 230, in one possible embodiment, the first conveying mechanism 120 is provided with lifting conveying mechanisms 150 at both ends. The conveying module 152 of the lifting conveying mechanism 150 can move up and down, so as to be connected to each return line 230 to realize the conveying of products. Similarly, the conveying module 152 of the lifting conveying mechanism 150 can move up and down, so as to be connected to the first conveying mechanism 120. Thus, the conveying module 152 can realize the transfer of products between the first conveying mechanism 120 and the return line 230.

[0072] To enable the first conveying mechanism 120 to connect with each return line 230, in another possible embodiment, a lifting power module is provided on one side of the frame 110. The lifting power module drives the first conveying mechanism 120 to move up and down, thereby enabling the first conveying mechanism 120 to connect with the return lines 230 on both sides. For example, when the first conveying mechanism 120 connects with the return line 230 of one device 200, the lifting power module drives the first conveying mechanism 120 to the corresponding height, thereby achieving docking between the first conveying mechanism 120 and the return line 230 of that device to achieve product conveying; when the first conveying mechanism 120 connects with the return line 230 of another device 200, the lifting power module drives the first conveying mechanism 120 to the corresponding height, thereby achieving docking between the first conveying mechanism 120 and the return line 230 of the other device to achieve product conveying.

[0073] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
