[0017] S2: When the tray device is about to reach the disk stopping device, the tray device continues to move, and the latch in the disk stopping device extends into the latch opening of the tray device facing the latch.

[0032] See also Figure 1 and Figure 2 The present invention provides a tray-type fixed-point conveying system, comprising: a conveying line 1, the conveying line 1 comprising a conveying driving surface 101 and a non-driving surface 102; a tray device 2, the tray device 2 is arranged on the conveying line 1, and a locking port 201 is arranged on the side of the tray device 2; and a disk stopping device 3, the disk stopping device 3 is arranged on one side of the conveying line 1; wherein, when the conveying line 1 drives the tray device 2 to reach one side of the disk stopping device 3, the disk stopping device 3 is locked into the tray device 2 through the locking port 201, so as to insert and stop the disk of the disk stopping device 3, and at the same time, the tray device 2 leaves the conveying driving surface 101 of the conveying line 1 and contacts with the non-driving surface 102 of the conveying line 1; after the insertion and stopping of the disk is completed, the disk stopping device 3 transfers the tray device 2 to the other side for storage in sequence along the height direction, and continues to switch to the disk stopping waiting state for other tray devices 2.

[0033] It is not difficult to find from the above content that in the process of conveying the pallet device 2 by the pallet-type fixed-point conveying system of the present invention, the conveyor line 1 is used to drive the pallet device 2 to move back and forth along the arrangement direction of the conveyor line 1. In the process of the conveyor line 1 driving the pallet device 2, the conveying drive surface 101 is used to contact the bottom side of the pallet device 2, thereby driving the pallet device 2 to move. Before the pallet device 2 is driven by the conveying drive surface 101 to reach the stopping device 3 at one end of the conveyor line 1 to stop and unload, when the stopping device 3 is gradually inserted into the locking port 201 on the pallet device 2, the pallet device 2 gradually leaves the conveying drive surface 101, and contacts the non-driving surface 102 to support the pallet device 2 through the non-driving surface 102, so as to achieve no influence of the driving of the conveying drive surface 101, thereby achieving pre-stop processing. As the disk-stopping device 3 is gradually inserted into the latch port 201, the tray device 2 will further drive the disk-stopping device 3 to be inserted into the tray device 2 until one side surface of the tray device 2 contacts the side surface of the disk-stopping device 3, thereby completing the complete insertion and stopping of the disk. In this way, the tray device 2 can be stably docked on one side of the disk-stopping device 3 to avoid the collision of the tray device 2 with the docking surface when docking. Moreover, since the bottom of the tray device 2 leaves the conveying drive surface 101, the problem that the tray device 2 still has power when the tray device 2 is stopped due to the continued driving of the conveying drive surface 101 and the bottom of the tray device 2 is worn by the conveying drive surface 101 can also be solved. In addition, the tray device 2 can be docked on one side of the disk-stopping device 3 while the conveying line remains in a non-stop state. After the tray device 2 is completely inserted into the disk-stopping device 3, the disk-stopping device 3 can also insert and rotate the locked tray device 2 to the other side of the disk-stopping device 3 after the tray device 2 is unloaded, and the other side of the disk-stopping device 3 can be transferred after each tray device 2 is unloaded, so as to realize the stacking storage of each tray device 2, reduce the space occupation, and do not need manual operation to complete the stacking process of the tray device 2. Similarly, when it is necessary to use the tray device 2 on the disk-stopping device 3, it is also possible to directly leave the disk-stopping device 3 from the disk-stopping device 3 through the drive of the tray device 2 to realize the removal of the tray device 2 from the disk-stopping device 3. Of course, it is also possible to use the disk-stopping device 3 as the starting point and transfer each tray device 2 on the disk-stopping device 3 to the conveyor line 1 in turn to complete operations such as return transportation.

[0034] It is worth noting that the pallet device 2 in the present invention can not only realize the stop control when reaching the stop assembly 3, but also can stop moving at any position of the conveyor line 1 by leaving the conveying drive surface 101 and contacting the non-drive surface 102 when the pallet device 2 is at any position of the conveyor line 1.

[0035] See also Figure 1and Figure 2 , Figure 1 and Figure 2 In one embodiment, the conveyor line 1 is a chain conveyor line, the conveying driving surface 101 corresponds to the top side of the chain of the chain conveyor line, and the non-driving surface 102 corresponds to the non-driving table surface of the chain conveyor line on the side of the conveying driving surface 101.

[0036] In one embodiment of the present invention, when the conveyor line 1 is a chain conveyor line, the upper part of the chain is arranged on one side of the top of the conveyor line 1 and corresponds to the conveying drive surface 101, that is, the upper part of the chain moves to drive the pallet device 2 above it to move together. When the pallet device 2 leaves the conveying drive surface 101, the corresponding pallet device 2 will contact the non-driving surface 102 of the conveyor line 1, that is, the pallet device 2 will contact the non-driving table surface on one side of the top of the chain conveyor line. Of course, the conveyor line 1 can also be other types of conveyor lines, such as roller conveyor lines, belt conveyor lines, etc., which can also drive the pallet device 2 of the present invention to move back and forth in the same way, and can also achieve the stop movement of the pallet 2 on the roller conveyor line or belt conveyor line through the corresponding structural form.

[0037] See also Figures 3 to 7 , Figures 3 to 7 In one embodiment, the tray device 2 includes: a tray shell 21, a telescopic slot 211 is provided at the bottom of the tray shell 21, and a locking port 201 is provided on the side of the tray shell 21; a locking assembly 22, the locking assembly 22 is installed in the tray shell 21, so that when the disk stopping device 3 is inserted into the locking port 201 and contacts with the locking assembly 22, the disk stopping device 3 continues to be driven to be locked along the guide direction of the locking port 201; a support frame 23, the support frame 23 is installed at the bottom of the tray shell 21 and is located above the non-driving surface 102; and a friction plate assembly 24, the friction plate assembly 24 is inserted in the telescopic slot 211, and one side of the bottom of the friction plate assembly 24 is located above the conveying drive surface 101; when the friction plate assembly 24 is retracted into the tray shell 21 along the guiding direction of the locking port 201, the support frame 23 contacts with the non-driving surface 102, so that one side of the bottom of the friction plate assembly 24 leaves the conveying drive surface 101.

[0038] In one embodiment of the present invention, the tray device 2 can be structurally configured so that the tray device 2 can be brought into contact with the conveying drive surface 101 through the friction plate assembly 24, so as to enable the tray device 2 to move along the guide direction of the conveying drive surface 101; after the friction plate assembly 24 leaves the conveying drive surface 101, the tray device 2 can be brought into contact with the non-driving surface 102 through the support frame 23, so as to enable the tray device 2 to stop at any position on the conveyor line 1.

[0039] In a preferred embodiment of the present invention, when the tray device 2 reaches one side of the disk stopping assembly 3, the disk stopping assembly 3 will gradually be inserted into the tray shell 21 through the locking port 201 on one side of the tray shell 21. As the disk stopping assembly 3 is continuously inserted, it will contact the locking assembly 22. When the disk stopping assembly 3 contacts the locking assembly 22, it may also correspond to the disk stopping assembly 3 contacting the pressure sensor installed on the tray shell 21 located on one side of the locking assembly 22, so that when the pressure sensor senses the arrival of the disk stopping assembly 3, it will automatically control the locking assembly 22 to drive the disk stopping device 3 to continue to lock into the tray shell 21; at the same time, the friction plate assembly 24 will gradually leave the conveying drive surface 101 of the conveyor line 1, and contact and support the non-driving surface 102 through the support frame 23, so that the tray device 2 is no longer affected by the driving force of the conveying drive surface 101, but through the self-driving action of the locking assembly 22, the tray device 2 is stably locked on one side of the disk stopping device 3, solving the problem of the tray device 2 hitting the docked surface when stopping.

[0040] See also Figure 5 and Figure 6 , Figure 5 and Figure 6 In a given embodiment, the locking assembly 22 includes: a mounting seat 221, which is mounted in the tray shell 21; a driving gear 222, which is mounted between the mounting seat 221 and the tray shell 21; and a driving motor 223, which is mounted on the mounting seat 221. When the disk-stopping device 3 contacts the driving gear 222, the driving gear 222 is connected to the disk-stopping device 3 in transmission.

[0041] In one embodiment of the present invention, the locking assembly 22 is transmission-connected with the disk-stopping device 3 so as to gradually stop at one side of the disk-stopping device 3. When the disk-stopping device 3 contacts the driving gear 222, the corresponding disk-stopping assembly 3 will also contact the pressure sensor installed on the tray shell 21. Thus, according to the pressure signal of the disk-stopping assembly 3 obtained by the pressure sensor, the driving motor 223, which is preferably a servo motor, is operated to drive the driving gear 222 to rotate. Through the mutual transmission between the driving gear 222 and the disk-stopping assembly 3, the tray device 2 continues to stably stop toward one side of the disk-stopping device 3 without directly colliding with the side of the disk-stopping device 3, thereby ensuring the stability of the tray device 2 when docked.

[0042] See also Figure 3 and Figure 4 , Figure 3 and Figure 4In one embodiment, the support frame 23 includes: a base frame 231; and a guide wheel 232, the guide wheel 232 is columnar, and the guide wheel 232 is installed at the bottom of the base frame 231 so as to contact the non-driving surface 102 when the friction plate assembly 24 leaves the conveying drive surface 101.

[0043] In one embodiment of the present invention, when the friction plate assembly 24 leaves the conveying drive surface 101 of the conveyor line 1, the corresponding support frame 23 will contact the non-driving surface 102 on the top side of the conveyor line 1 through the guide wheel 232 at the bottom of the base frame 231, so as not to be affected by the driving force of the conveying drive surface 101. At the same time, when the disk stopping assembly 3 contacts the locking assembly 22, the driving gear 222 is driven to rotate by the driving motor 223 to drive the disk stopping assembly 3, so that when the tray device 2 moves toward one side of the disk stopping device 3, it rolls and contacts the non-driving surface 102 through the guide wheel 232, so as to facilitate the mobility of the tray device 2 when it moves toward the disk stopping device 3, and solve the friction formed by the support frame 23 on the surface of the non-driving surface 102 when the tray device 2 moves.

[0044] See also Figure 4 , Figure 7 and Figure 8 , Figure 4 , Figure 7 and Figure 8 In one embodiment, the friction plate assembly 24 includes: a friction telescopic block 241, the lower end of the friction telescopic block 241 is movably inserted in the telescopic groove 211, a guide groove 2411 is provided on the side of the friction telescopic block 241, and the first surface 24111 at the bottom of the guide groove 2411 is arranged in an inclined shape, and the top side of the friction telescopic block 241 is elastically connected to the inner top of the tray shell 21 through an elastic member 2412; a guide block 242, one end of the guide block 242 is movably inserted in the guide groove 2411, and the plane where the second surface 2421 on the bottom side of one end of the guide block 242 is located is parallel to the plane where the first surface 24111 is located and contacts each other, and the guide length of the second surface 2421 is greater than the width of the first surface 24111; and a driving assembly 243, the driving assembly 243 is installed in the tray shell 21, and the power output end of the driving assembly 243 is connected to the guide block 242.

[0045] In one embodiment of the present invention, during the up-and-down movement of the friction plate assembly 24 in the telescopic groove 211, the friction telescopic block 241 is slidably inserted into the telescopic groove 211, and the top side of the friction telescopic block 241 is connected to the inner top of the tray housing 21 through an elastic member 2412 which is preferably a spring. When the friction telescopic block 241 is in an extended state, so that the bottom of the friction telescopic block 241 contacts the conveying drive surface 101, the guide block 242 at this time reaches the maximum stroke under the driving action of the driving assembly 243, and at the maximum stroke, the guide block 242 is completely inserted into the guide groove 2411, and because the second surface 2421 of the guide block 242 contacts the first surface 24111 of the guide groove 2411, the friction telescopic block 241 is pushed out toward the bottom side of the tray housing 21, so that the bottom of the friction telescopic block 241 contacts the surface of the conveying drive surface 101, thereby realizing the driving movement of the tray device 2 through the conveying drive surface 101. It is worth noting that the straight track formed by the movement of the friction telescopic block 241 driven by the driving assembly 243 is arranged parallel to the top surface of the tray shell 21, and the first surface 24111 and the second surface 2421 are arranged inclined relative to the top surface of the tray shell 21.

[0046] When it is necessary to move the friction telescopic block 241 away from the conveying drive surface 101 and make the bottom side of the support frame 23 contact the surface of the non-driving surface 102, the driving component 243 will pull the guide block 242 to gradually move in the direction of leaving the guide groove 2411. At this time, the second surface 2421 and the first surface 24111 remain in contact with each other under the pulling force of the elastic member 2412 on the friction telescopic block 241, so that the friction telescopic block 241 moves toward the tray shell 21, and when the height of the bottom of the friction telescopic block 241 from the bottom of the tray shell 21 is less than the height of the bottom of the support frame 23 from the bottom of the tray shell 21, the bottom of the support frame 23 will contact the surface of the non-driving surface 102, thereby realizing the mutual switching of the friction telescopic block 241 and the support frame 23 when providing support.

[0047] It is worth noting that a friction plate is installed at the bottom of the friction telescopic block 241 to improve the driving performance of the conveying driving surface 101 on the friction telescopic block 241 through the contact between the friction plate and the conveying driving surface 101 .

[0048] See also Figure 5 and Figure 7 , Figure 5 and Figure 7In a given embodiment, the driving assembly 243 includes: a driving screw rod 2431, and both ends of the driving screw rod 2431 are respectively threadedly connected to a guide block 242; a gear box 2432, the gear box 2432 is installed in the tray shell 21, and the transmission force output end of the gear box 2432 is connected to the driving screw rod 2431; and a driving unit 2433, and the power output end of the driving unit 2433 is connected to the transmission force input end of the gear box 2432.

[0049] In one embodiment of the present invention, when the driving component 243 drives the guide block 242 to move toward the maximum stroke and the minimum stroke, a thread groove corresponding to the driving screw 2431 is opened on the guide block 242, so that the driving unit 2433, which is preferably a servo motor, can drive the gear box 2432, so that the driving screw 2431 is driven to rotate by the gear box 2432, so that the two ends of the driving screw 2431 are respectively extended and retracted in the corresponding thread grooves on the guide block 242, so that the guide block 242 is driven to move back and forth along the axial direction of the driving screw 2431, so that when the guide block 242 moves toward the direction away from the end of the driving screw 2431, it moves toward the direction of the maximum stroke; and when the guide block 242 moves toward the direction close to the end of the driving screw 2431, it moves toward the direction of the minimum stroke.

[0050] See also Fig. 9 and Fig.10 , Fig. 9 and Fig.10 In one embodiment, the disk stopping device 3 includes: a plug-in assembly 31, wherein a plurality of plug-in assemblies 31 are stacked and transmission-connected between the upper and lower plug-in assemblies 31 so that the upper plug-in assembly 31 can rotate relative to the lower plug-in assembly 31; a lifting unit 32, wherein the lifting unit 32 is disposed below the plug-in assembly 31, and a power output end of the lifting unit 32 is connected to the bottom of the plug-in assembly 31 at the bottom layer; and a guide bracket 33, wherein the lifting unit 32 is installed on the bottom side of the guide bracket 33, and the top side of the guide bracket 33 is disposed on a guide space 331 for guiding the plug-in assembly 31 that has completed rotation.

[0051] In one embodiment of the present invention, when the tray device 2 stops on the stop device 3, the corresponding layer of the stacked plug-in components 31 will pass through the latch port 201 on one side of the tray device 2, so that when the plug-in components 31 reach the maximum depth of the tray device 2, the tray device 2 stops moving, thereby achieving a stable parking of the tray device 2 on one side of the plug-in components 31. At the same time, after the tray device 2 has completed the parking of the plug-in components 31, the lifting unit 32 will first move the stacked plug-in components 31 upward for a short distance, so that the tray device 2 moves upward away from the conveyor line 1. Then, a plug-in assembly 31 located at the lower layer will drive a plug-in assembly 31 on the upper layer that has just been plugged into the tray device 2 to rotate to the other side. Then, the lifting unit 32, which is preferably a push rod motor, drives the stacked plug-in assemblies 31 to move downward by at least the height of a tray device 2 again, so that the two ends of the tray device 2 that has just rotated to the other side enter the guide space 331 on the top side of the guide bracket 33, so that the guide space 331 limits each plug-in assembly 31 moving downward, and each plug-in assembly 31 limited by the guide space 331 is plugged with a tray device 2, so that the tray devices 2 are stored in sequence using each plug-in assembly 31 located in the guide space 331. When it is necessary to put the tray device 2 back on the conveyor line 1, the lifting unit 32 can also be used to drive the plug-in assembly 31 of each layer to move upward, and then the tray device 2 can be rotated to the conveyor line 1 again, so that the tray device 2 can be reversely transported through the conveyor line 1.

[0052] See also Fig.10 , Fig.10 In a given embodiment, the plug-in assembly 31 includes: a steering seat 311, a mounting groove is provided in the middle of the top of the steering seat 311; a locking member 312, the locking member 312 is installed on one side of the steering seat 311, and the locking member 312 and the locking port 201 are correspondingly arranged; and a driving motor 313, the driving motor 313 is installed in the mounting groove, and the power output end of the driving motor 313 is connected to another steering seat 311 corresponding to its top.

[0053] In one embodiment of the present invention, when the plug-in assembly 31 is rotated and switched, the tray device 2 is docked and locked by inserting the latch 312 into the tray device 2 through the latch port 201. After the tray device 2 completes the locking of the latch 312, the steering seat 311 of one plug-in assembly 31 below the plug-in assembly 31 that has just completed the locking can be driven by the rotation motor 313 on the steering seat 311 of the top plug-in assembly 31 to rotate to another, so that the latch 312 on one side of the steering seat 311 will be inserted with the tray device 2 and transferred to the other side to store the tray device 2.

[0054] Preferably, the latch 312 is a rack, and one end of the latch 312 is elastically and rotationally connected to the steering seat 311. In this embodiment, the driving gear 222 on the locking assembly 22 of the tray device 2 and the tooth surface on the latch 312 which is a rack are meshed and transmitted, so that the latch 312 can be driven by the driving gear 222 to move back and forth along the guide direction of the latch port 201. And when the latch 312 is gradually inserted, the latch 312 can adaptively find the corresponding driving teeth on the driving gear 222 to mesh with the driving gear 222. It is worth noting that the rotation angle range of the latch 312 is relatively small to prevent the latch 312 from being separated from the driving teeth of the driving gear 222 along the radial direction of the driving gear 222 when the latch 312 rotates due to elasticity.

[0055] In summary, the present invention discloses a pallet-type fixed-point conveying system, which, through the mutual cooperation between the conveyor line 1 and the pallet device 2, can realize that when the pallet device 2 contacts the conveying drive surface 101 of the conveyor line 1, the conveying drive surface 101 moves the pallet device 2, and when the pallet device 2 leaves the conveying drive surface 101 and contacts the non-driving surface 102, the pallet device 2 can be stopped at any position on the conveyor line 1 without stopping the conveyor line 1, and is not affected by the driving force of the conveying drive surface 101. Through the cooperation between the tray device 2 and the disk stopping device 3, it can be realized that when the tray device 2 is driven by the conveying driving surface 101 and is about to reach the side of the disk stopping device 3, the tray device 2 leaves the conveying driving surface 101 and contacts the non-driving surface 102 during the process of inserting the disk stopping device 3 into the latch port 201 of the tray device 2, and switches to the transmission of the disk stopping device 3 by the tray device 2, so that the tray device 2 can automatically dock the disk stopping device 3 without stopping the operation of the conveying line 1 by self-driving, solving the problem of the tray device 2 hitting the docking surface when docking. Moreover, after the tray device 2 docks the disk stopping device 3, the tray device 2 can be transferred to the other side by the disk stopping device 3 for automatic stacking storage, reducing the space occupied by the tray device 2. At the same time, when the tray device 2 needs to be reused, the disk stopping device 3 can be used to transfer the tray devices 2 of each layer to the conveying line 1 one by one for continued transportation, so as to ensure the flexibility of the use of the tray device 2 during transportation. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0056] The present invention also provides a method for using a tray-type fixed-point conveying system, comprising the following steps:

[0057] S1: placing the goods to be transported on the pallet device 2, and driving the pallet device 2 and the goods through the conveying driving surface 101 in the conveying line 1;

[0058] S2: When the tray device 2 is about to reach the disk stopping device 3, the tray device 2 continues to move, and the latch 312 in the disk stopping device 3 extends into the latch opening 201 of the tray device 2 facing the latch 312. At this time, the driving motor 223 drives the driving gear 222 to rotate, so that the driving gear 222 and the latch 312 are engaged;

[0059] S3: When the latching member 312 is inserted into the latching port 201, the guide block 242 is pulled from the guide groove 2411 on the friction telescopic block 241 toward the middle of the tray housing 21 through the driving assembly 243. At this time, the linkage elastic member 2412 simultaneously pulls the friction telescopic block 241 toward the inside of the tray housing 21, so that the friction plate at the bottom of the friction telescopic block 241 leaves the conveying drive surface 101 and switches to be supported by the support frame 23 on the non-driving surface 102, and the latching member 312 continues to complete the insertion action of the tray device 2;

[0060] S4: After the insertion and stopping of the tray device 2 and the latch 312 are completed, the goods on the tray device 2 are unloaded, and the steering seat 311 on which the tray device 2 is parked is driven to rotate by the driving motor 313. The steering seat 311 drives the tray device 2 to rotate synchronously through the latch 312, and the tray device 2 is turned to the rear of the stopping device 3. Then, the stacked insertion components 31 are lowered to at least the height of the tray device 2 by the lifting unit 32, so that the two ends of the tray device 2 just rotated to the other side enter the guide space 331 on one side of the top of the guide bracket 33, so as to store the tray device 2 once.

[0061] S5: Cargo transportation to the next stage.
