Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to an automatic delivery line for tooling vehicles. Background Art

[0002] The palletizing unloading robot uses a tooling cart to place the products that need to be palletized. Currently, the tooling cart is generally sent manually. The tooling cart is sent manually to the left and right workstations of the palletizing unloading robot. When one workstation is full, it will automatically switch to another workstation.

[0003] The applicant has found that the prior art has at least the following technical problems:

[0004] When the docking cycle is fast, the tooling carts will be frequently turned over. However, when the palletizing robot quickly fills up the tooling carts (for example, one cart every 3 minutes), since there are only 2 workstations for the tooling carts, if the manual placement of the carts is not completed within 3 minutes, the equipment will stop. In addition, manual transportation often requires finding the tooling carts and then pulling the carts. The 3-minute cache time is often not enough, causing the palletizing equipment to stop frequently. Summary of the invention

[0091] The transposition unit 7 is disposed between the first buffer unit 1 and the second buffer unit 2, and can perform unit transposition of the tooling vehicles 200 on the two buffer units.

[0092] The automatic conveyor line for tooling vehicles 200 provided by the present invention can realize automatic delivery of tooling vehicles 200 and has the function of positioning the tooling vehicles 200. The tooling vehicles 200 have the function of caching multiple tooling vehicles 200 for loading and unloading, thereby reducing the turnover frequency of the tooling vehicles 200 and reducing the situation of stacking shutdown caused by the tooling vehicles 200 not being in place. Manual transportation is not required, which greatly improves efficiency, shortens transportation time, and improves stacking rhythm.

[0093] The automatic conveying line of the tooling vehicle 200 of the present invention solves the distribution problem of the tooling vehicle 200 and also solves the buffering problem of the tooling vehicle 200.

[0099] As an optional embodiment of the present invention, Figure 24-26 As shown, the first stacking unit 5 and the second stacking unit 6 have the same structure, both comprising a stacking frame 51, a stacking chain 52, a stacking motor 53, and a stacking lifting cylinder 54; wherein:

[0100] The stacking chain 52 is arranged on the top of the stacking frame 51;

[0101] The stacking motor 53 is in driving connection with the stacking chain 52;

[0102] There are four stacking lifting cylinders 54 , which are arranged in a rectangular shape inside the stacking frame 51 .

[0103] Specifically, the stacking lifting cylinder 54 is installed on the base at the bottom and connected to the stacking frame 51 at the top, which can drive the stacking frame 51 to rise and fall, thereby achieving a height match with the unloading height of the unloading robot 9 and the height between the first cache unit 1 and the second cache unit 2.

[0104] As an optional embodiment of the present invention, Figure 27-Figure 29 As shown, the transposition unit 7 includes a trolley track 71, a transfer trolley 72, a transfer track 73, a transfer motor 74143, a translation motor 75, and a translation chain 76; wherein:

[0105] The translation chain 76 is arranged in the trolley track 71 and connected to the transfer trolley 72;

[0106] The transfer trolley 72 is movably arranged on the trolley track 71 and can translate along the trolley track 71. It should be noted that in order to prevent the transfer trolley 72 from leaving the trolley track 71, the transfer trolley 72 and the trolley track 71 should be connected by a limited sliding connection. Specifically, the tire of the transfer trolley 72 is a triangular structure with a concave middle, that is, there is a slot in the middle of the tire, and the angle iron of the trolley track 71 is flattened into a convex triangle, that is, the cross-section of the trolley track 71 is a triangle. The tire of the transfer trolley 72 is clamped on the trolley track 71 through the slot and will not derail.

[0107] The translation motor 75 is in transmission connection with the translation chain 76;

[0110] As an optional embodiment of the present invention, Figure 1-Figure 4 As shown, the first cache unit 1 and the second cache unit 2 have the same structure, and both include a rotation module 11, a cache module 12 and a positioning module 13 arranged in sequence; the transposition unit 7 is connected to the cache module 12; the positioning module 13 is arranged outside the first stacking unit 5 or the second stacking unit 6 to position the transported tooling vehicle 200.

[0111] Further, such as Figure 5-Figure 8As shown, the buffer module 12 includes multiple sections of transfer lines 14 , each section of the transfer line 14 can carry a tooling vehicle 200 ; all the transfer lines 14 are connected end to end; and the transposition unit 7 is connected between two adjacent sections of the transfer line 14 .

[0112] The present invention forms a plurality of buffer stations by setting up a plurality of transfer lines 14. By increasing the buffer stations and automatically conveying materials between adjacent transfer lines 14, the tooling vehicles 200 on the transfer lines 14 can be conveyed to the stacking unit in sequence for palletizing, and then the palletized tooling vehicles 200 are automatically transported to the unloading unit 4 for conveying.

[0113] As a further improvement of the present invention, Figure 9-12 As shown, the rotating module 11 includes a base plate 111, a three-stage reduction gear set 112, a rotating motor 113, a first lifting cylinder 114, a top plate 115, a rotating seat 116, a rotating belt 117, and a transmission motor 118; wherein:

[0114] The three-stage reduction gear set 112 is arranged on the base plate 111; it should be noted that the three-stage reduction gear set 112 is composed of three transmission gears of different specifications, specifically, a small gear, a middle gear and a large gear, and the small gear, the middle gear and the large gear are arranged in sequence;

[0115] The rotating motor 113 is drivingly connected to the pinion gear in the three-stage reduction gear set 112;

[0116] The top plate 115 is drivingly connected to the large gear in the three-stage reduction gear set 112;

[0117] The rotating seat 116 is connected to the top plate 115 through the first lifting cylinder 114; the rotating seat 116 can be raised and lowered by the first lifting cylinder 114 to match the height of the loading unit 3 and the transfer line 14;

[0118] The rotating belt 117 is arranged on the rotating seat 116;

[0119] The transmission motor 118 is transmission-connected to the rotating belt 117 .

[0120] As a further improvement of the present invention, Figure 18-Figure 20 As shown, the positioning module 13 includes a positioning frame 131, a hooking cylinder 132, a side push cylinder 133, a first roller group 134 and a second roller group 135; wherein:

[0121] The first roller set 134 is disposed on a side wall inside the positioning frame 131;

[0122] The second roller set 135 is placed on the other side wall inside the positioning frame 131;

[0123] The side thrust cylinder 133 is disposed outside the positioning frame 131 and is connected to the second roller assembly 135 after passing through the positioning frame 131;

[0124] There are two hooking cylinders 132 , which are respectively arranged on both sides of the positioning frame 131 .

[0125] As a further improvement of the present invention, Figure 13-Figure 17 As shown, the transfer line 14 includes a transfer frame 141, a transfer chain 142, a transfer motor 74143, and a chain tensioning mechanism 144; wherein:

[0126] The transfer chain 142 is arranged on the top of the transfer frame 141;

[0127] The transfer motor 74143 is in driving connection with the transfer chain 142;

[0128] The chain tensioning mechanism 144 is disposed between the transfer chain 142 and the transfer frame 141 .

[0129] As a further improvement of the present invention, Fig.14 As shown, the chain tensioning mechanism 144 includes a tensioning sprocket mounting plate 1441, a fixing plate 1442, an adjusting screw 1443, an adjusting hole 1444, and a pin 1445; wherein:

[0130] Two rows of waist-shaped adjustment holes 1444 are provided on the tensioning sprocket mounting plate 1441;

[0131] The pin 1445 passes through the adjustment hole 1444 and is connected to the transfer frame 141;

[0132] The driven sprocket of the transfer chain 142 is rotatably arranged on the tensioning sprocket mounting plate 1441 via a rotating shaft;

[0133] The fixing plate 1442 is fixed on the transfer frame 141;

[0134] The adjusting screw 1443 is threadedly connected to the fixing plate 1442 , and is connected to the tensioning sprocket mounting plate 1441 after passing through the fixing plate 1442 .

[0135] When in use, the depth of the adjusting screw 1443 screwed into the fixing plate 1442 is controlled, thereby driving the tensioning sprocket mounting plate 1441 to move forward and backward, thereby achieving the tensioning of the transfer chain 142 .

[0136] The automatic conveyor line for tooling vehicles 200 provided by the present invention increases the number of tooling vehicles 200 cached. Originally, there was only one tooling vehicle 200 waiting, but now there can be at least four. Originally, the tooling vehicle 200 needed to be manually turned over every 3 minutes, but now it can be turned over every 12 minutes, thereby reducing equipment downtime caused by untimely turnover of the tooling vehicles 200. The extra tooling vehicles 200 can be automatically, quickly and accurately transported to the stacking station.

[0137] It should be noted that any unit with a chain is also provided with a sprocket tensioning mechanism for adjusting the tension of the chain.

[0138] It should also be noted that the chain structure in all units of the present invention includes a chain, a driving sprocket and a driven sprocket. The motor drives the driving sprocket, and the rotation of the driving sprocket drives the chain and the driven sprocket to move, thereby completing the movement of the tooling vehicle 200 located on the chain.

[0139] In the present invention, the KIVA trolley 100 is used to transport the tooling vehicle 200 in the loading unit 3 and the unloading unit 4. The KIVA trolley 100 is a prior art, which is a back-loaded logistics robot that can carry the tooling vehicle 200 for movement. However, since it is relatively wide, it can only enter from the long side of the tooling vehicle 200. After entering, the KIVA trolley 100 will lift the tooling vehicle 200 and carry the tooling vehicle 200 to the loading position. Since the KIVA trolley 100 is a prior art, the present invention will not elaborate on it. The unloading robot 9 is also a prior art product, and the present invention does not make any improvements on it, so it will not be elaborated on.

[0140] like Fig.32 As shown, it is a transportation flow diagram of the tooling vehicle 200 in the automatic conveyor line of the tooling vehicle 200 of the present invention. It can be seen that the transportation flow direction of the tooling vehicle 200 in the first cache unit 1 is from the loading unit 3 to the first cache unit 1 and finally enters the first stacking unit 5. When there is a tooling vehicle 200 in the first stacking unit 5, the tooling vehicle 200 sent to the first cache unit 1 again will enter the second cache unit 2 and then enter the second stacking unit 6 under the drive of the transposition unit 7. When the tooling vehicle 200 in the first stacking unit 5 is full, it moves in the opposite direction from the first stacking unit 5 to the transposition unit 7, and then passes through the second cache unit 2 to the unloading unit 4, and then is sent away; when the tooling vehicle 200 in the second stacking unit 6 is full, it moves in the opposite direction from the second stacking unit 6 to the second cache unit 2, and then is transported to the unloading unit 4, and finally is transported away by the KIVA trolley 100.

[0141] The working principle of the automatic conveyor line of the tooling vehicle 200 of the present invention is:

[0142] After the KIVA cart 100 moves to the loading unit 3 with the empty tooling cart 200, it puts down the tooling cart 200. Since the KIVA cart 100 is relatively wide, it can only enter from the long side of the tooling cart 200. Then the KIVA cart 100 rises and lifts the tooling cart 200 to the same height as the loading unit 3. After putting down the tooling cart 200, the KIVA cart 100 leaves. At this time, the tooling cart 200 falls on the loading and unloading conveying chain 32 of the loading unit 3. The rotation of the loading and unloading conveying chain 32 can drive the tooling cart 200. At this time, there is a height difference with the rear section of the tooling cart 200 rotating module 11, so the loading unit 3 also needs to be lifted as a whole to dock the tooling cart 200 rotating module 11. After the height is aligned, the loading and unloading motor 33 drives the loading and unloading conveying chain 32 to send the tooling cart 200 on the loading and unloading conveying chain 32 to the next process: the tooling cart 200 rotating module 11.

[0143] The unloading unit 4 has the same structure as the loading unit 3. When the tooling vehicle 200 is transported to the unloading unit 4, the KIVA vehicle 100 is called to pull the tooling vehicle 200 away into the warehouse.

[0144] Rotation module 11: The main function of this station is to rotate the tooling vehicle 200 90°, so that the horizontal tooling vehicle 200 becomes a vertical tooling vehicle 200, which is convenient for the robot behind to load the product. This rotation module 11 drives the reducer through a rotating motor 113, and then drives two large reduction gears (three-stage reduction gear set 112). The last large gear is connected to the rotating seat 116, so that the rotating seat 116 can carry the tooling vehicle 200 to rotate. There is a rotating belt 117 on the rotating seat 116 to drive the tooling vehicle 200. There are also two first lifting cylinders 114 on the rotating seat 116 for lifting the rotating seat 116 to make it the same height as the transfer line 14 station behind. After the height is the same, the rotating motor 113 drives the rotating belt 117, and the rotating belt 117 drags the tooling vehicle 200 to transport the tooling vehicle 200 to the empty transfer line 14.

[0145] There are three empty vehicle transfer lines 14 (caching stations): these three transfer lines 14 are used to cache the tooling vehicles 200. When there are vacancies in these three transfer lines 14, the tooling vehicles 200 will park on the front transfer line 14 first. When the front is full, they will retreat in turn. When there is a vacancy in the front, the rear will fill it up immediately. The transfer line 14 is also driven by the transfer motor 74143 to drive the transfer chain 142, and the transfer chain 142 drags the tooling vehicles 200 to run. It should be noted here that the front transfer line 14 refers to the transfer line 14 close to the stacking unit.

[0146] There are three full-car transfer lines 14 (buffer stations): the structures of these three transfer lines 14 are exactly the same as those of the empty-car transfer lines 14, and they are all used to buffer the full-carriage tooling vehicles 200. The loaded vehicles will be parked on the rear transfer line 14 first, and the rear ones will be moved forward in turn when they are full. When there is a vacancy at the rear, the front ones will be filled immediately. The full-car transfer line 14 is also driven by the transfer motor 74143 to drive the transfer chain 142, and the transfer chain 142 drags the tooling vehicle 200 to run;

[0147] Transposition unit 7 (horizontal transfer station): It is composed of a horizontal transfer trolley and a horizontal trolley track 71. This transposition unit 7 is a link between the previous and the next. First, the empty tooling trolley 200 must be transported to the two stacking units in front. The stacking unit will also transport the full tooling trolley 200 to the full-car transfer line 14 through the horizontal transfer trolley. The structure of the transposition unit 7 is mainly that the tooling trolley 200 transfer trolley moves left and right on the trolley track 71. The horizontal transfer trolley has tires that are stuck on the trolley track 71. The translation motor 75 carries the translation chain 76 to drag the horizontal transfer trolley to move left and right. At the same time, the horizontal transfer trolley itself has a transfer track 73 that moves forward and backward, and the transfer motor 74143 drags the transfer track 73 to move forward and backward. Therefore, the tooling trolley 200 can move forward, backward, left and right at this station, and the front and rear tooling trolleys 200 can be reasonably mobilized according to needs.

[0148] There are two stacking stations 8, which are located on the left and right sides of the unloading robot 9 respectively. These two stacking stations 8 are the working positions of the unloading robot 9. When the work truck 200 stops at this station, the unloading robot 9 can place the products in the work truck 200 in turn. If one of the stacking stations 8 is full, it will be stacked in the other stacking station 8. After the work truck 200 at the first stacking station 8 is full, it will be transported away. After the work truck 200 at the second stacking station 8 is full, it will be transported away. Moreover, when the second stacking station 8 is full, the full work truck 200 at the first stacking station 8 has also been circulated, and the products can continue to be stacked on the empty work truck 200 located at the first stacking station 8, and the operation is circulated left and right.

[0149] Corresponding to the two stacking stations 8, a first stacking unit 5 and a second stacking unit 6 are respectively provided. The structures of the two stacking units are exactly the same. The two stacking units have the function of overall rising and falling, and are lifted as a whole by four stacking lifting cylinders 54. Because the tooling vehicle 200 needs to be placed on the ground and accurately positioned by the tooling vehicle 200 positioning module 13 to meet the requirements of the unloading robot 9 for loading materials, but during the transportation of the tooling vehicle 200, each station lifts the tooling vehicle 200. The tires of the tooling vehicle 200 are off the ground at other stations, and this station needs to put them down, so there is an overall lifting mechanism. There are two positioning modules 13 for the tooling vehicle 200, which are located at two stacking units respectively: after the tooling vehicle 200 flows to the stacking unit and is put down, the three side push cylinders 133 in the positioning module 13 push the tooling vehicle 200 to one side, and then the two hooking cylinders 132 fix the tooling vehicle 200 front and back. The side push fixes the left and right positions, and the hook fixes the front and back positions. Therefore, the front, back, left and right positions of the tooling vehicle 200 are fixed. Each tooling vehicle 200 is positioned by this positioning module 13 to ensure that each tooling vehicle 200 stops at exactly the same position, which is convenient for the unloading robot 9 to operate.

[0150] The operation process of the automatic conveyor line of the tooling vehicle 200 of the present invention is shown in Fig.32 :

[0151] The unloading robot 9 loads products in the tooling carts 200 of the first stacking unit 5 and the second stacking unit 6 of the two stacking stations 8. If the tooling cart 200 of the first stacking unit 5 is full of products, the tooling cart 200 of the first stacking unit 5 is transported to the horizontal transfer trolley in the transposition unit 7 through the transfer line 14. The horizontal transfer trolley moves the fully loaded tooling cart 200 horizontally to the transfer line 14 in the second buffer unit 2, and the fully loaded tooling cart 200 is buffered from back to front. The tooling cart 200 is placed on the chain of the transfer line, and the tooling cart 200 will move forward and backward with the control motor.

[0152] Turnover: The KIVA trolley 100 transports the empty tool cart 200 to the loading unit 3, and the transfer line 14 of the first buffer unit 1 will be filled with empty carts from front to back in sequence, so as long as there is a vacant position, the tool cart 200 can be placed at the end of the empty car transfer line 14. The transfer line 14 in the second buffer unit 2 will also preferentially transport the full tool cart 200 to the end of the full car transfer line 14 to facilitate manual forklift turnover. As long as there is no car at the end of the full car transfer line 14, the full car will move to the end station.

[0153] It should be noted that the number of the transfer lines 14 in the first buffer unit 1 and the second buffer unit 2 can be increased or decreased according to actual needs.

[0154] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
