[0056] At present, in the production scene of lithium battery, optical film, printing and papermaking and cable industry, the full roll material cylinder and the empty roll material cylinder required for production need to be carried by the transportation device and connected with the machine table for taking and placing. Therefore, how to improve the transportation efficiency of the transportation device has become a problem to be solved.

[0057] Based on the above technical problem, the application provides a transportation device, which comprises a base, a first lifting mechanism and a second lifting mechanism. The first lifting mechanism can be used to support the full roll material cylinder, and the second lifting mechanism can be used to support the empty roll material cylinder. By setting the transportation device as a double-station structure, the transportation process can be simplified, thereby facilitating the improvement of the transportation efficiency of the transportation device in the transportation process.

[0058] The transportation device provided by the embodiments of the application can be applied to a battery production equipment as a component thereof, and of course, the transportation device can also be used independently.

[0059] Please refer to Figures 1 to 3 According to the embodiment of the present application, a conveying device is provided, comprising a base 1, a first lifting mechanism 2 and a second lifting mechanism 3. The first lifting mechanism 2 comprises a first support 21, a first lifting piece 22 and a first driving assembly 23. The first support 21 is arranged on the top of the base 1. The first lifting piece 22 comprises a pair of first lifting frames 221 arranged in pairs and spaced along the length direction Y of the base 1. Each first lifting frame 221 is provided with a first bearing groove 2211 on the side away from the base 1 along the height direction X of the base 1. The first driving assembly 23 is in driving connection with each first lifting frame 221, so as to drive the first driving assembly 23 to move relative to the first support 21 along the height direction X. The second lifting mechanism 3 is arranged on one side of the first lifting mechanism 2 along the width direction Z of the base 1. The second lifting mechanism 3 comprises a second lifting piece 31 and a second driving assembly 32. The second lifting piece 31 comprises a pair of second lifting frames 311 arranged in pairs and spaced along the length direction Y. Each second lifting frame 311 is provided with a second bearing groove 3111 on the side away from the base 1 along the height direction X. The second lifting frame 311 is arranged in one-to-one correspondence with the first lifting frame 221. The second driving assembly 32 is in driving connection with each second lifting frame 311, so as to drive the second lifting frame 311 to move relative to the first lifting frame 221 along the first direction A. The first direction A intersects with the height direction X, the length direction Y and the width direction Z.

[0060] The height direction X is a direction perpendicular to the plane of the base 1. The length direction Y is a direction extending along the long side of the base 1. The width direction Z is a direction extending along the short side of the base 1. The first direction A can be an inclined direction or a composite direction.

[0061] It should be noted that the conveying device provided by the embodiment of the present application can be an AGV (Automated Guided Vehicle). The conveying device is used for conveying full roll material cylinders and empty roll material cylinders. The base 1 can be the body of the AGV. The base 1 can comprise a driving wheel system, a battery module, an obstacle avoidance / navigational radar, a safety warning light, a safety touch edge and the like.

[0062] The base 1 can be understood as the chassis of the conveying device, which is used for driving and positioning. The first lifting mechanism 2 is used for supporting the full roll material cylinder and connecting the full roll material cylinder with a machine table (a gravure machine, a coating machine or a cold press machine) and a shelf. The second lifting mechanism 3 is used for supporting the empty roll material cylinder and connecting the empty roll material cylinder with the machine table (the gravure machine, the coating machine or the cold press machine) and the shelf.

[0063] Of course, the first lifting mechanism 2 can also be used for supporting the empty roll material cylinder, and the first lifting mechanism 2 can also be used for supporting the full roll material cylinder. For the convenience of description, the first lifting mechanism 2 will be used for supporting the full roll material cylinder, and the second lifting mechanism 3 will be used for supporting the empty roll material cylinder in the following description.

[0064] The full roll material cylinder refers to a cylinder in which a substrate is wound, and the empty roll material cylinder refers to a cylinder in which no substrate is wound. Specifically, the full roll material cylinder can be supported in the first bearing groove 2211 of one of the first lifting frames 221 along one side of the axial direction of the full roll material cylinder, and can be supported in the first bearing groove 2211 of the other first lifting frame 221 along the other side of the axial direction of the full roll material cylinder. The empty roll material cylinder can be supported in the second bearing groove 3111 of one of the second lifting frames 311 along one side of the axial direction of the empty roll material cylinder, and can be supported in the second bearing groove 3111 of the other second lifting frame 311 along the other side of the axial direction of the empty roll material cylinder. The axial direction of the full roll material cylinder and the empty roll material cylinder is the length direction Y of the base 1.

[0065] It should be noted that the first lifting mechanism 2 can be provided as one or multiple, and correspondingly, the second lifting mechanism 3 can be provided as one or multiple.

[0066] The first support 21 is fixed to the top of the base 1, and is used to support the first lifting member 22. The first lifting member 22 includes two first lifting frames 221 to ensure the stability of supporting the full roll material cylinder. The first lifting frame 221 is recessed inward to form a first bearing groove 2211 along the height direction X away from the side surface of the base 1, and the first bearing groove 2211 is used to bear the full roll material cylinder or to be connected with other mechanisms.

[0067] Optionally, in the projection plane perpendicular to the length direction Y, the orthographic projection of the first bearing groove 2211 can be one of a U-shaped structure and a V-shaped structure.

[0068] In this way, the positioning of the full roll material cylinder is facilitated, and the support of the full roll material cylinder is also improved to prevent it from being pulled out of the first bearing groove 2211 along the width direction Z, which is beneficial to improve the reliability of the conveying device.

[0069] The first driving assembly 23 is connected between the first lifting frame 221 and the first support 21, and is used to drive the first lifting frame 221 to move relative to the first support 21 along the height direction X respectively, so as to realize the lifting of the first lifting frame 221 along the height direction X, and to realize the taking and placing of the full roll material cylinder by being connected with the machine table.

[0070] The second lifting member 31 includes two second lifting frames 311 to ensure the stability of supporting the empty roll material cylinder. The first lifting frame 221 can also be used to support the second lifting frame 311, and by arranging the second lifting frame 311 on the side of the first lifting frame 221 along the width direction Z, the space of the base 1 in the width direction Z can be fully utilized, and the layout is reasonable.

[0071] The second lifting frame 311 is recessed inward along the height direction X from a side surface of the base 1 to form a second bearing groove 3111, and the second bearing groove 3111 is used to bear the empty roll cylinder or to be connected with other mechanisms.

[0072] Optionally, in a projection plane perpendicular to the length direction Y, the orthographic projection of the second bearing groove 3111 can be one of a U-shaped structure and a V-shaped structure.

[0073] In this way, the positioning of the empty roll cylinder is facilitated, and the support of the empty roll cylinder is also improved to prevent it from being pulled out of the second bearing groove 3111 along the width direction Z, thereby improving the reliability of the conveying device.

[0074] The second driving assembly 32 is connected to the first lifting frame 221 and the second lifting frame 311, and is used to drive the second lifting frame 311 to move relative to the first lifting frame 221 along the first direction A to realize the lifting of the second lifting frame 311 along the height direction X to be connected with the machine table to realize the taking and placing of the empty roll cylinder.

[0075] It should be noted that although the second lifting frame 311 can move relative to the first lifting frame 221 along the first direction A, the first direction A is arranged to intersect the height direction X, so that the second lifting frame 311 can also change the position along the height direction X, and in this way, the second lifting frame 311 can be prevented from moving directly along the height direction X to interfere with the full roll cylinder supported on the first lifting mechanism 2, thereby improving the reliability of the conveying device.

[0076] The connection task of the conveying device with the machine table roll end includes taking down the empty roll cylinder and connecting and placing the full roll cylinder, and the conveying device in the related art usually only has one lifting mechanism, and the connection task needs to be divided into two tasks for execution, which has a long process and low transportation efficiency.

[0077] However, in the embodiment of the present application, the first lifting mechanism 2 capable of supporting the full roll cylinder and the second lifting mechanism 3 capable of supporting the empty roll cylinder are arranged on the base 1, and the first lifting mechanism 2 and the second lifting mechanism 3 are independently driven to operate, which can increase the single carrying capacity of the conveying device, so that more transportation tasks can be completed in the same time, thereby improving the transportation efficiency. In addition, since the conveying device provided by the embodiment of the present application can simultaneously process the materials of two stations, the accumulation and waiting time of the materials on the production line can be reduced, the production process is optimized, and the space occupation is reduced.

[0078] In some optional embodiments, the included angle between the first direction A and the height direction X is greater than or equal to 5° and less than or equal to 30°.

[0079] If the included angle between the first direction A and the height direction X is set too large, i.e. greater than 30°, the overall size of the conveying device in the width direction Z will be increased, which increases the size limit of the conveying device in the width direction Z, and in order to ensure that the second lifting frame 311 can be lifted to the corresponding height, the overall size of the conveying device in the height direction X may also be increased, which increases the size limit of the conveying device in the height direction X, and in addition, due to the too large inclination angle of the second lifting frame 311, it is also easy to cause uneven stress and affect the stability of movement. If the included angle between the first direction A and the height direction X is set too small, i.e. less than 5°, it is possible that the empty roll cylinder supported on the second lifting frame 311 will interfere with the full roll cylinder supported on the first lifting frame 221.

[0080] Therefore, by setting the included angle between the first direction A and the height direction X to be between 5° and 30°, and including both end values of 5° and 30°, it is possible to ensure that the empty roll cylinder and the full roll cylinder supported on the conveying device will not interfere, and it is also possible to reduce the size limit of the conveying device in the width direction Z and the height direction X, thereby facilitating the improvement of the structural compactness of the conveying device.

[0081] Further, in some alternative embodiments, the included angle between the first direction A and the height direction X is greater than or equal to 5° and less than or equal to 20°.

[0082] Further, in some alternative embodiments, the included angle between the first direction A and the height direction X is greater than or equal to 8° and less than or equal to 15°.

[0083] By setting in the above manner, the structural compactness of the conveying device can be further improved.

[0084] Please continue to refer to Figure 1 and Figure 2 In some alternative embodiments, along the length direction Y, the first support 21 and the first driving assembly 23 are both located between the pair of first lifting frames 221.

[0085] By setting in the above manner, the overall size of the conveying device in the length direction Y can be reduced, so as to reduce its limit in the length direction Y, which is conducive to improving the structural compactness of the conveying device.

[0086] As shown in Figure 1 In some alternative embodiments, the first support 21 includes a pair of first supports 211 which are spaced apart along the length direction Y and correspondingly arranged with the first lifting frames 221.

[0087] Each first support 211 corresponds to support a first lifting frame 221, and the above arrangement is favorable to reduce the weight of the first support 21, thereby being favorable to reduce the weight of the whole transportation device, and can prevent the first support 21 from interfering with the full roll material cylinder supported by the first lifting mechanism 2.

[0088] Please refer to Figure 2 In some optional embodiments, the transportation device further comprises a first guide assembly 4, and each first lifting frame 221 is provided with the first guide assembly 4 between the first lifting frame 221 and the first support 21 along the length direction Y. The first guide assembly 4 comprises a first guide rail and a first sliding block in sliding connection. The first guide rail extends along the height direction X. One of the first support 21 and the first lifting frame 221 is provided with the first guide rail, and the other is provided with the first sliding block.

[0089] The transportation device provided by some embodiments of the present application further comprises the first guide assembly 4 to ensure the stability of the lifting movement of the first lifting frame 221 relative to the first support 21. The first guide rail extends along the height direction X, which is favorable to improve the accuracy of the movement of the first lifting frame 221 along the height direction X and prevent the first lifting frame 221 from deviating and shaking, so as to ensure that the first lifting frame 221 can move to the corresponding position accurately and improve the docking accuracy between the transportation device and the machine table.

[0090] In addition, the first guide assembly 4 is arranged between the first lifting frame 221 and the first support 21 along the length direction Y, which is reasonable in layout and facilitates assembly.

[0091] Optionally, the number of the first guide assemblies 4 is four, and each first lifting frame 221 is provided with two first guide assemblies 4 between the first lifting frame 221 and the first support 211, and the two first guide assemblies 4 located between the first lifting frame 221 and the first support 211 are distributed along the width direction Z, which is favorable to better improve the stability of the movement of the first lifting frame 221 along the height direction X.

The first driving member 231 is connected with the first gear set 232 and configured to drive the first gear set 232 to rotate to drive the first transmission shaft 2331 and the lead screw 2332 to rotate.

[0099] The first driving member 231 is a power source for driving the first lifting frames 221 to move along the height direction X, which can be an electric motor or a motor for providing driving force. The first gear set 232 is used for transmitting power and can distribute torque and change the transmission direction to connect the first driving member 231 and the first transmission member 233. The first transmission shaft 2331 connects the first gear set 232 and the lead screw 2332 for transmitting rotary motion. The lead screw 2332 converts the rotary motion into the linear motion of the nut 2333 along the height direction X through threaded rotation. The nut 2333 is connected with the first lifting frame 221 to drive the first lifting frame 221 to move along the height direction X.

[0100] The first lifting mechanism 2 provided by some embodiments of the present application can realize the synchronous movement of the first lifting frames 221 on both sides by using one first driving member 231, which can ensure the synchronization of the two first lifting frames 221 and also help to reduce the cost and weight of the transport device.

[0101] Optionally, the first driving assembly 23 further comprises a speed reducer, which is connected between the first driving member 231 and the first gear set 232 along the width direction Z, and is used to convert the high rotation speed and low torque output by the first driving member 231 into low rotation speed and high torque to adapt to the input requirements of the first gear set 232.

[0102] Optionally, the first driving assembly 23 further comprises a shaft coupling, and the first gear set 232 and the first transmission shaft 2331 are provided with the shaft coupling. The shaft coupling can allow a certain degree of angular deviation compensation to reduce the stress caused by assembly errors or thermal deformation and help to ensure the stability of the transmission between the first gear set 232 and the first transmission shaft 2331.

[0103] Optionally, a shaft coupling is arranged between the first transmission shaft 2331 and the lead screw 2332, which helps to ensure the stability of the transmission between the first transmission shaft 2331 and the lead screw 2332.

[0104] Optionally, a gear is arranged between the first transmission shaft 2331 and the lead screw 2332, and the gear is used to transmit power.

[0105] Specifically, the working principle of the first lifting mechanism 2 is that the first driving member 231 and the speed reducer output power at the middle position of the conveying device along the length direction Y, so as to drive the first gear set 232 to transmit power, and the first gear set 232 synchronously transmits power to the shaft couplings arranged on both sides of the first gear set 232 and the first transmission shaft 2331. Each first transmission shaft 2331 drives the gear to rotate through the shaft coupling, and the gear drives the lead screw 2332 to rotate. The nut 2333 can move along the height direction X under the rotation of the lead screw 2332, so as to drive the first lifting frame 221 to move along the height direction X.

[0106] The first lifting frame 221 can move along the height direction X under the synchronous action of the first guide assembly 4 and the nut 2333, which is beneficial to improve the stability of the lifting of the first lifting frame 221.

[0107] In some optional embodiments, the first transmission shaft 2331 extends along the length direction Y.

[0108] The conveying device provided by some embodiments of the present application can rotate the first transmission shaft 2331 around the length direction Y as the axis, which is beneficial to the transmission layout between the first transmission shaft 2331 and other components, and the layout is reasonable.

[0109] In some optional embodiments, the first driving member 231 is connected to the side of the first gear set 232 away from the second lifting mechanism 3 along the width direction Z.

[0110] The conveying device provided by some embodiments of the present application can fully utilize the space on the side of the first lifting mechanism away from the second lifting mechanism along the width direction Z, so as to reduce the volume of the conveying device, prevent the first driving member 231 from interfering with the second lifting mechanism, and improve the compactness of the conveying device.

[0111] In some optional embodiments, the first driving member 231, the first gear set 232 and the first transmission shaft 2331 are arranged in the base 1, and the lead screw 2332 and the nut 2333 are arranged in the first support member 21.

[0112] The first driving member 231, the first gear set 232 and the first transmission shaft 2331 are all arranged in the base 1, which means that the base 1 further comprises a housing, at least one of the modules included in the base 1, such as the driving wheel system and the battery module, can be arranged in the housing or can be arranged in the housing, and the first driving member 231, the first gear set 232 and the first transmission shaft 2331 are all arranged in the housing to achieve the protective effect of the first driving member 231, the first gear set 232 and the first transmission shaft 2331, and also make the whole transportation device more clean and beautiful. In addition, such a design can make full use of space, reasonable layout, and help to improve the space utilization rate of the transportation device.

In addition, such a design can make full use of space, reasonable layout, and help to improve the space utilization rate of the transportation device.

[0114] Please refer to Figures 2 to 4 In some optional embodiments, the second driving assembly 32 comprises a second driving member 321, a second transmission shaft 322 and two second transmission members 323, the second transmission member 323 is arranged one-to-one with the second lifting frame 311, the second transmission member 323 comprises a second gear set 3231 and a rack guide 3232 engagedly connected, the rack guide 3232 extends along the first direction A, the first lifting frame 221 is provided with the rack guide 3232 along the width direction Z towards one side of the second lifting frame 311, and the second lifting frame 311 is provided with the second gear set 3231 along the height direction X towards one side of the base 1. The second driving member 321 is connected with one of the second gear sets 3231 and is configured to drive the one of the second gear sets 3231 to rotate to drive the second transmission shaft 322 and the other of the second gear sets 3231 to rotate.

[0115] The second driving member 321 is a power source for driving the second lifting frame 311 to move along the first direction A, which can be an electric motor or a motor for providing driving force. The second transmission shaft 322 is connected between the two second gear sets 3231 for power transmission. The second transmission shaft 322 is engagedly connected with the rack guide 3232 to convert the rotary motion into linear motion along the first direction A to drive the second lifting frame 311 to move linearly along the first direction A.

[0116] The transportation device provided by some embodiments of the present application is characterized in that the second lifting mechanism 3 is provided with a second driving member 321 to realize synchronous movement of the two second lifting frames 311, which can ensure the synchronization of the two second lifting frames 311 and reduce the cost and weight of the transportation device.

[0117] In addition, the transmission mode of the gear and the rack is adopted, which can ensure the stable lifting of the second lifting frame 311 and improve the load capacity and the service life of the transportation device.

[0118] Optionally, the second driving assembly 32 further comprises a speed reducer connected between the second driving member 321 and the second gear set 3231 along the length direction Y, which is used to convert the high rotation speed and low torque output by the second driving member 321 into low rotation speed and high torque to meet the input requirement of the second gear set 3231.

[0119] Specifically, the working principle of the second lifting mechanism 3 is that the second driving member 321 and the speed reducer on one side of the transportation device along the length direction Y output power to drive the second gear set 3231 on the same side to rotate along the rack guide rail 3232, and the second gear set 3231 on the other side of the transportation device along the length direction Y is driven by the second transmission shaft 322 to rotate along the rack guide rail 3232 synchronously, so as to drive the second lifting frame 311 to move linearly along the first direction A.

[0120] The second lifting frame 311 can move along the first direction A under the synchronous action of the second guide assembly 5 and the second transmission member 323, which can improve the stability of the lifting of the second lifting frame 311.

[0121] Please refer to Figure 1 and Figure 5 In some optional embodiments, the transportation device further comprises a limiting member 6, and the second lifting mechanism 3 further comprises a second support member comprising a pair of second supports 331 arranged and spaced apart along the length direction Y, and the second lifting member 31 is located between the pair of second supports 331 along the length direction Y, and each second support 331 is provided with a limiting member 6 on the side away from the base 1 along the height direction X. The second lifting frame 311 can be switched between the first position and the second position, and the height of the second lifting frame 311 in the first position is higher than that in the second position along the height direction X, and in the second position, the orthographic projection of the second bearing groove 3111 in the length direction Y at least partially falls into the limiting member 6.

[0122] It should be noted that the limiting piece 6 is arranged on the second support 331, and its position will not change with the lifting of the second lifting frame 311. The second lifting frame 311 can move relative to the first lifting frame 221 along the first direction A to switch between the first position and the second position. In the first position, the second lifting frame 311 can be docked with the machine table to take or place materials. Then the second lifting frame 311 can be lowered to the second position to facilitate subsequent transportation by the transportation device.

[0123] It can be understood that the empty roll material cylinder is relatively light in weight, and in the transportation process of the transportation device, the empty roll material cylinder can be displaced along the length direction Y, or even fall out of the second bearing groove 3111. Therefore, the transportation device provided in some embodiments of the present application can limit the two sides of the empty roll material cylinder along the length direction Y by arranging the limiting piece 6, so as to ensure that the empty roll material cylinder will not fall out of the second bearing groove 3111 along the length direction Y in the transportation process of the transportation device, so as to ensure that the empty roll material cylinder is always supported in the second bearing groove 3111, and the docking accuracy of the second lifting piece 31 with the machine table is ensured.

[0124] Optionally, the limiting piece 6 can be arranged as a baffle or other structure.

[0125] As shown in Figure 5 some optional embodiments, the limiting piece 6 includes a limiting plate 61 arranged apart from the second lifting frame 311 along the length direction Y.

[0126] The spacing between the limiting plate 61 and the second bearing groove 3111 determines the range in which the empty roll material cylinder can move along the length direction Y. Through the above arrangement, it can be ensured that the empty roll material cylinder will not fall out of the groove, and the freedom of movement of the empty roll material cylinder along the length direction Y can be provided.

[0127] Optionally, in the second position, the orthographic projection of the second bearing groove 3111 along the length direction Y at least partially falls into the limiting plate 61.

[0128] Optionally, the extension surface of the limiting plate 61 can be arranged inclined relative to the height direction X.

[0129] As shown in Figure 5 some optional embodiments, the limiting piece 6 further includes a limiting body 62 connected to one side of the limiting plate 61 along the length direction Y facing the second lifting frame 311. The limiting body 62 is recessed inward on the side facing away from the second support 331 along the height direction X to form a limiting groove 621. The limiting groove 621 is in communication with the second bearing groove 3111 along the length direction Y.

[0130] When the second lifting frame 311 supports the empty roll material cylinder in the first position and moves to the second position, a part of the empty roll material cylinder can be supported in the second supporting groove 3111, and another part can be supported in the limiting groove 621. Due to the limitation of the limiting plate 61, the empty roll material cylinder can only be supported in the second supporting groove 3111 and the limiting groove 621.

[0131] In addition, during the transportation process, the empty roll material cylinder supported by the second lifting frame 311 can move in the length direction Y due to vibration. Specifically, the empty roll material cylinder can move between the second supporting groove 3111 and the limiting groove 621. The limiting groove 621 is used to constrain the movement track of the empty roll material cylinder to prevent it from falling out. In addition, the limiting body 62 is connected with the limiting plate 61, which can also improve the structural strength of the limiting plate 61 to prevent it from deforming, thereby improving the overall structural strength of the limiting piece 6.

[0132] In some optional embodiments, in a projection plane perpendicular to the length direction Y, the orthographic projection of the limiting body 62 is one of a U-shaped structure and a V-shaped structure.

[0133] In this way, the positioning of the empty roll material cylinder is facilitated, and the support of the empty roll material cylinder is also improved to prevent it from falling out of the second supporting groove 3111 or being deflected in the width direction Z, thereby improving the reliability of the transportation device.

[0134] Please refer to Figures 1 to 3 In some optional embodiments, the transportation device further comprises a first detection assembly 7 and a controller. Each first lifting frame 221 is provided with a first detection assembly 7 on the side facing away from the second lifting mechanism 3 in the width direction Z. The first detection assembly 7 is configured to detect the distance between the full roll material cylinder supported by the first lifting mechanism 2 and the first detection assembly 7 in the length direction Y. The controller is electrically connected with the first detection assembly 7, the first driving assembly 23, and the second driving assembly 32 and is configured to control the base 1, the first driving assembly 23, and the second driving assembly 32 to stop running.

[0135] The controller can be arranged in the base 1.

[0136] By arranging the first detection assembly 7 on the side of the first lifting frame 221 facing away from the second lifting mechanism 3 in the width direction Z, interference between the first detection assembly 7 and the second lifting frame 311 can be prevented, and the layout is reasonable, thereby improving the structural compactness of the transportation device.

[0137] The first detection assembly 7 is arranged in one-to-one correspondence with the first lifting frame 221. In this way, the accuracy of the detection structure of the first detection assembly 7 can be improved.

[0138] The first detection assembly 7 is configured to detect the distance between the first detection assembly 7 and the full roll cylinder supported by the first lifting mechanism 2 in the length direction Y, so as to detect whether the full roll cylinder is deviated, and to ensure the accuracy of the position of the full roll cylinder.

[0139] The controller is electrically connected with all the first detection assemblies 7, and the first detection assemblies 7 can transmit the detected distance data to the controller in the form of electrical signals. The controller can determine whether the full roll cylinder supported by the first lifting mechanism 2 is deviated according to the received signals. When the full roll cylinder is deviated, the controller controls the base 1, the first driving assembly 23 and the second driving assembly 32 to stop running, so as to remind the worker to timely adjust the position of the full roll cylinder. After the full roll cylinder is returned to the correct position, the base 1 resumes running.

[0140] In the above manner, the position of the full roll cylinder can be detected in real time, so as to prevent the collision or material jam caused by the deviation of the full roll cylinder, to ensure the stable running of the conveying device, and to ensure the accuracy of the subsequent docking with the machine table, which is beneficial to improve the docking efficiency between the conveying device and the machine table. In addition, the need for manual inspection can be reduced, and the working difficulty can be reduced.

[0141] Optionally, the first detection assembly 7 can include but is not limited to any one of a laser ranging assembly, an ultrasonic detection assembly and a photoelectric sensor.

[0142] For example, the first detection assembly 7 can emit a first light beam along the length direction Y to obtain the distance between the first detection assembly 7 and the full roll cylinder supported by the first lifting mechanism 2 in the length direction Y. When the obtained distance is not equal to a preset distance value, or exceeds a limit deviation of the preset distance value, the controller controls the base 1 to stop running.

[0143] In some optional embodiments, the conveying device can further include an alarm module, and the controller is electrically connected with the alarm module and is configured to control the start and stop of the alarm module. When the controller controls the base 1 to stop running, the controller also controls the alarm module to start. The alarm module can emit sound or light to prompt the worker to timely adjust the position of the full roll cylinder.

[0144] Please refer to Figure 2 In some optional embodiments, the conveying device further includes a second detection assembly 8, and the controller is further electrically connected with the second detection assembly 8. The second detection assembly 8 is arranged in the first bearing groove 2211 and is configured to detect whether the full roll cylinder is loaded in the first bearing groove 2211.

[0145] The second detection assembly 8 can transmit the detection result to the controller in the form of an electrical signal. If the full roll material cylinder is detected in the first bearing groove 2211, the conveying device continues the conveying process, such as driving or lifting of the first lifting mechanism 2. If the full roll material cylinder is not detected in the first bearing groove 2211, the controller controls the base 1, the first driving assembly 23 and the second driving assembly 32 to stop running.

[0146] In some optional embodiments, the second bearing groove 3111 is provided with a second detection assembly 8, and the first detection assembly 7 is configured to detect whether the empty roll material cylinder is carried in the second bearing groove 3111.

[0147] The second detection assembly 8 can transmit the detection result to the controller in the form of an electrical signal. If the full roll material cylinder is detected in the first bearing groove 2211, the conveying device continues the conveying process, such as driving or lifting of the first lifting mechanism 2. If the full roll material cylinder is not detected in the first bearing groove 2211, the controller controls the base 1, the first driving assembly 23 and the second driving assembly 32 to stop running.

[0148] Optionally, the second detection assembly 8 can include, but is not limited to, any one of a photoelectric sensor, a pressure sensor and a trigger limit switch.

[0149] In some optional embodiments, the first detection assembly 7 includes an emitter 81 and a receiver 82 which are spaced apart along the width direction Z. The emitter 81 is configured to emit a light beam along the width direction Z, and the receiver 82 is configured to receive the light beam.

[0150] For example, when the full roll material cylinder is carried in the first bearing groove 2211, the light beam emitted by the emitter 81 is blocked by the full roll material cylinder, and the receiver 82 does not receive the light beam, and the conveying device runs normally. When the receiver 82 receives the light beam, it indicates that the light beam emitted by the emitter 81 is not blocked by the full roll material cylinder, i.e., the first bearing groove 2211 does not carry the full roll material cylinder, and the controller controls the base 1 to stop running.
