[0039] Example 1

[0040] See also Figure 1-10 , the present invention provides a technical solution:

[0041] An automatic tray feeding mechanism includes a bracket 1 and a full material seat 2. The bracket 1 and the full material seat 2 are both common existing structures and will not be described in detail herein. The mechanism also includes:

[0042] A material taking seat 10, which is movably arranged on the bracket 1;

[0043] The mobile material taking unit 3 is arranged on the bracket 1 and connected to the material taking seat 10, and is used to control the material taking seat 10 to shift to the bottom of the full material seat 2, and can take away the bottom tray and put the product on the tray;

Through the setting of the feeding assembly 4, the three-axial adjustment of the product box 410 is realized, which is conducive to putting the products into the partition layer in the tray in sequence;

[0046] The middle part of the material taking seat 10 is a hollow structure, and the adjusting member 5 includes a cylinder 51 arranged on the bracket 1, and a receiving plate 52 for placing a tray is arranged at the end of the cylinder 51, and the receiving plate 52 can movably penetrate the material taking seat 10;

[0047] The shift assembly 6 includes a driving motor 61 disposed on the bracket 1, a driving screw 62 is disposed at the output end of the driving motor 61, one side of the material taking seat 10 is threadedly connected to the driving screw 62, and the material taking seat 10 is slidably disposed on the bracket 1, and a clamping member 7 is disposed on the material taking seat 10 for clamping and positioning the tray;

[0048] The clamping member 7 includes two cylinders 71 respectively arranged on both sides of the material taking seat 10, and the ends of the cylinders 71 are provided with positioning side plates 72. The two sides of the material taking seat 10 are respectively provided with blanking side plates 73. The positioning side plates 72 cooperate with the tray structure, which is conducive to improving the positioning effect of the tray.

[0049] The pallet control unit 8 is arranged on the bracket 1, and is used to control the pallet on the full material seat 2, and can cooperate with the mobile material taking unit 3 to release the lowermost pallet;

[0050] The tray control unit 8 includes two lifting frames 81 slidably arranged on the bracket 1, the tops of the lifting frames 81 are connected to the full material seat 2, the bracket 1 is provided with a cylinder 3 82, the end of the cylinder 3 82 is connected to any lifting frame 81, the bracket 1 is provided with a blanking support plate 83 for guiding the pallet filled with products, the full material seat 2 is provided with a positioning member 9 for positioning the pallet on the full material seat 2, and the position of the blanking support plate 83 is provided with a transfer structure for transporting the pallet with the product placed to the next station, which is a common existing structure and will not be described in detail here. The blanking support plate 83 is provided to facilitate the normal falling of the product through the guidance of the blanking support plate 83 after the product is placed, which is conducive to avoiding the misalignment of the pallet and improving the accuracy of pallet unloading;

[0051] The positioning member 9 includes two cylinder fours 91 respectively arranged at the bottom of the full-filled seat 2, and a positioning plate 92 is arranged on each of the cylinder fours 91. The positioning plate 92 is slidably arranged on the full-filled seat 2. By setting the positioning plate 92 and cooperating with the adjustment of the lifting frame 81 and the full-filled seat 2 by the cylinder three 82, the pallet at the bottom of the full-filled seat 2 can be positioned and released. As shown in the accompanying drawings of the specification, there are inwardly recessed grooves on both sides of the pallet in the figure, which allows the positioning plate 92 to be inserted exactly between the two pallets, and then after the lowermost pallet is released, the positioning of the second-to-last pallet can be achieved.

[0052] When in use, in the initial state, the material taking seat 10 is located at the initial position, not in contact with the bottom of the full material seat 2, and the trays are stacked on the full material seat 2 and positioned by the positioning member 9;

[0053] During operation, the shifting assembly 6 of the mobile material taking unit 3 is started, and the driving motor 61 drives the material taking seat 10 to move toward the bottom of the full material seat 2. The cylinder 3 82 of the tray control unit 8 drives the lifting frame 81 to descend, so that the lowermost tray descends slightly, and the cylinder 2 71 of the clamping member 7 pushes the positioning side plate 72 to clamp the tray. Then, the cylinder 4 91 controls the positioning plate 92 to cancel the positioning of the lowermost tray, and the cylinder 3 82 drives the lifting frame 81 to rise, so that the full material seat 2 releases the lowermost tray. After rising to a certain position, the cylinder 4 91 controls the positioning plate 92 to position the second to last tray, and the material taking seat 10 carries the tray out from under the full material seat 2.

[0054] The loading assembly 4 starts working, the cylinder 1 51 pushes the receiving plate 52 up, and drives the shift frame 41, the shift frame 1 44 and the shift frame 2 47 to move through the first motor 42, the second motor 45 and the third motor 48, and puts the products in the product box 410 into the tray in turn. After that, the mobile picking unit 3 moves the tray with the products to the blanking support plate 83 position, and controls the positioning side plate 72 through the cylinder 2 71 to cancel the positioning of the tray, and the tray falls along the blanking support plate 83 to the next workstation. At this time, the picking seat 10 is also located under the full material seat 2, which avoids the need for the mobile picking unit 3 to be adjusted again, which is beneficial to reducing the workload. The cylinder 3 82 of the tray control unit 8 drives the lifting frame 81 to rise again to prepare for the next tray feeding.

[0055] According to the above content, when there are inwardly recessed grooves on both sides of the tray, the second-to-last tray can be positioned by extending the positioning side plate 72 between the two trays. However, if the side of the tray to be fed is a smooth flat structure, how should it be designed?

[0056] Example 2

[0057] See also Figure 11-13 , the present invention provides a technical solution:

[0058] Different from Example 1, the present scheme provides another implementation manner of the positioning member 9: the positioning member 9 includes a fixed shaft 93 rotatably arranged at the bottom of the full-filled seat 2, a gear 94 is arranged on the fixed shaft 93, a shift rack 95 used in conjunction with the gear 94 is slidably arranged on the bracket 1, a connecting plate 96 is arranged at the end of the shift rack 95, a spring 97 is arranged on the connecting plate 96, a bonding plate 98 is arranged at the end of the spring 97, and a fixed rack 99 used in conjunction with the gear 94 is arranged on the frame body. The setting of the fixed rack 99 enables the gear 94 to rotate when the cylinder three 82 drives the lifting frame 81 and the full-filled seat 2 to shift, thereby driving the shift rack 95 to shift, thereby realizing the forward movement of the connecting plate 96 and the bonding plate 98. The setting of the spring one 97 improves the clamping effect of the pallet.

[0059] When in use, in the initial state, the material taking seat 10 is located at the initial position, not in contact with the bottom of the full material seat 2, and the trays are stacked on the full material seat 2 and positioned by the positioning member 9;

[0060] During operation, the shifting assembly 6 of the mobile material taking unit 3 is started, and the driving motor 61 drives the material taking seat 10 to move toward the bottom of the full material seat 2. The cylinder 3 82 of the tray control unit 8 drives the lifting frame 81 to descend, so that the lowermost tray descends slightly, and the cylinder 2 71 of the clamping member 7 pushes the positioning side plate 72 to clamp the tray. When the lifting frame 81 and the full material seat 2 descend, the fixed fixed rack 99 can drive the gear 94 to rotate, driving the shift rack 95 to shift, thereby realizing the displacement of the connecting plate 96 and the bonding plate 98 to both sides, that is, The positioning of the pallet is cancelled, and the cylinder 3 82 drives the lifting frame 81 to rise, so that the full material seat 2 releases the lowermost pallet. When the lifting frame 81 and the full material seat 2 rise, the gear 94 rotates in the opposite direction, driving the shift rack 95 to shift in the opposite direction, thereby realizing the displacement of the connecting plate 96 and the bonding plate 98 toward the penultimate pallet, that is, realizing the positioning of the pallet, and the material taking seat 10 carries the pallet out from under the full material seat 2, which can be applicable to a variety of pallet structures with different sides, and also reduces the setting of electric drive equipment, which is energy-saving and environmentally friendly;

[0061] The loading assembly 4 starts working, the cylinder 1 51 pushes the receiving plate 52 up, and drives the shift frame 41, the shift frame 1 44 and the shift frame 2 47 to move through the first motor 42, the second motor 45 and the third motor 48, and puts the products in the product box 410 into the tray in turn. After that, the mobile picking unit 3 moves the tray with the products to the blanking support plate 83 position, and controls the positioning side plate 72 through the cylinder 2 71 to cancel the positioning of the tray, and the tray falls along the blanking support plate 83 to the next workstation. At this time, the picking seat 10 is also located under the full material seat 2, which avoids the need for the mobile picking unit 3 to be adjusted again, which is beneficial to reducing the workload. The cylinder 3 82 of the tray control unit 8 drives the lifting frame 81 to rise again to prepare for the next tray feeding.

[0062] According to the above content, pallets are all of fixed height, but if the height of the pallets to be fed is of different sizes, how should they be designed?

[0063] Example 3

[0064] See also Figure 14-15 , the present invention provides a technical solution:

[0065] Different from Example 2, a positioning ring 11 is provided on the full-filled seat 2, a boss 12 is provided on the fixed shaft 93, the boss 12 and the positioning ring 11 are coaxially arranged, a plurality of circular grooves 13 are provided on the positioning ring 11, springs 14 are provided in the circular grooves 13, a locking ball 15 is provided at the end of the spring 14, a slot 16 for cooperating with the locking ball 15 is provided on the boss 12, the slot 16 on the boss 12 can cooperate with the locking ball 15, so that when the gear 94 is disengaged from the fixed rack 99, the fixed shaft 93 will not rotate, thereby ensuring the positioning of the pallet, that is, no matter what the height of the pallet is, the normal positioning effect can be achieved. Of course, this clamping force is certain, but it is sufficient for an empty shell pallet without products.

[0066] When in use, in the initial state, the material taking seat 10 is located at the initial position, not in contact with the bottom of the full material seat 2, and the trays are stacked on the full material seat 2 and positioned by the positioning member 9;

[0067] During operation, the shifting assembly 6 of the mobile material taking unit 3 is started, and the driving motor 61 drives the material taking seat 10 to move toward the bottom of the full material seat 2. The cylinder three 82 of the tray control unit 8 drives the lifting frame 81 to descend, so that the lowermost tray descends slightly, and the cylinder two 71 of the clamping member 7 pushes the positioning side plate 72 to clamp the tray. When the lifting frame 81 and the full material seat 2 descend, the fixed fixed rack 99 can drive the gear 94 to rotate, driving the shifting rack 95 to shift, thereby realizing the displacement of the connecting plate 96 and the bonding plate 98 to both sides, that is, canceling the positioning of the tray, and the cylinder three 82 drives the lifting frame 81 to rise, so that the full material seat 2 is released. For the tray at the bottom, when the lifting frame 81 and the full material seat 2 rise, the gear 94 rotates in the opposite direction, driving the shift rack 95 to shift in the opposite direction, thereby realizing the displacement of the connecting plate 96 and the bonding plate 98 toward the penultimate tray, that is, realizing the positioning of the tray. If the tray is higher, the gear 94 and the fixed rack 99 need to be disengaged. At this time, the locking ball 15 is engaged in the slot 16 under the action of the spring 2 14, realizing the positioning of the tray. The material taking seat 10 carries the tray out from under the full material seat 2, which can be applicable to a variety of tray structures with different sides, and also reduces the setting of electric drive equipment, which is energy-saving and environmentally friendly.

[0068] The loading assembly 4 starts working, the cylinder 1 51 pushes the receiving plate 52 up, and drives the shift frame 41, the shift frame 1 44 and the shift frame 2 47 to move through the first motor 42, the second motor 45 and the third motor 48, and puts the products in the product box 410 into the tray in turn. After that, the mobile picking unit 3 moves the tray with the products to the blanking support plate 83 position, and controls the positioning side plate 72 through the cylinder 2 71 to cancel the positioning of the tray, and the tray falls along the blanking support plate 83 to the next workstation. At this time, the picking seat 10 is also located under the full material seat 2, which avoids the need for the mobile picking unit 3 to be adjusted again, which is beneficial to reducing the workload. The cylinder 3 82 of the tray control unit 8 drives the lifting frame 81 to rise again to prepare for the next tray feeding.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
