[0025] A second aspect of the present invention provides a method for tray loading of a filled or bottled product, comprising the following steps:

[0026] (1) The empty conveying station moves to the bottom of the tray dispensing module;

[0027] (2) A stack of pallets is placed in the tray separation module. The upper and lower pallets are moved inward and inserted between the two pallets on the bottom layer. The upper pallet moves upward and lifts all the pallets except the bottom pallet. At the same time, the lower pallet presses the edge of the bottom pallet, separating the bottom pallet from the other pallets and dropping it into the conveying station below.

[0028] (3) The conveying station carries the pallet and moves to the bottom of the machine head;

[0029] (4) a product conveying mechanism delivers the filled or bottled products in batches to the die head, and the die head positions the plurality of filled or bottled products and drops them into the tray;

[0031] In a preferred embodiment, in step (4), the product conveying mechanism diverts the product to multiple conveying channels via multiple spacers;

[0032] Move the partitions of the die head so that the product channel formed between the partitions is connected to the corresponding conveying channel. At this time, the support rod is located below the product channel to receive the product;

[0033] When a predetermined number of products enter each of the product channels, the partition is moved so that the support rod avoids the bottom of the product channel, the can drop channel between the product channel and the support rod is aligned in the vertical direction, and the products fall onto the positioning plate of the machine head; at this time, the positioning plate is carried upward by the can drop plate to the bottom of the support rod, and the second through hole on the positioning plate is opposite to the bottom of the can drop channel, and the products fall into the second through hole through the positioning guide pillars around the second through hole, and the first through hole and the second through hole on the can drop plate of the machine head are staggered with each other;

[0034] The can dropping plate carries the positioning plate downward to the top of the tray, and the positioning plate is moved horizontally to align the first through hole and the second through hole, so that the product falls into the tray below the can dropping plate.

[0035] The present invention adopts the above solution and has the following advantages compared with the prior art:

[0036] The pallet loading machine of the present invention has an unloading mechanism located below the product conveying mechanism and aligned with the pallet conveying mechanism, resulting in a relatively small overall footprint. Upper and lower pallets separate the bottommost pallet, which is then moved to the bottom of the machine head by the pallet conveying mechanism. The machine head then positions the product received from the product conveying mechanism and drops it onto the pallet. Finally, the conveying station carries the loaded pallet to the unloading mechanism, where it is unloaded. This results in a high degree of automation for product loading, improving both work efficiency and production capacity. Furthermore, the machine can be easily adapted to the specifications of the pallets to meet varying loading requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] Reference Figures 14 to 18 As shown, the machine head 4 includes a frame 50, a mounting frame 41, a plurality of partitions 42 arranged on the mounting frame 41, a plurality of support rods 43 arranged on the mounting frame 41, a can drop plate 44 movably arranged on the mounting frame 41 in the up and down directions, and a positioning plate 45 movably arranged on the can drop plate 44 in the horizontal direction.

[0075] Reference Figure 1 As shown, the frame 50 is sleeved on the mounting frame 41 and is higher than the mounting frame 41 . A door panel 502 is provided on the front side of the frame 50 , and the rear side and left and right sides of the frame 50 are all open.

[0076] The machine head 4 is provided with a first cylinder 47, a second cylinder 48 and a third cylinder 49. The mounting frame 41 includes a flat plate 411, and the first cylinder 47 is provided on the flat plate 411 to drive the plurality of partitions 42 to move forward and backward. More specifically, referring to Figure 15 As shown, the lower surface of the flat plate 41 is provided with a slide rail 412 extending left and right, and the partition 42 is guided by the slide rail 412 to move in the front and rear directions; there are two second cylinders 48, which are set on the left and right sides of the can drop plate 44; the third cylinder 49 is used to drive the positioning plate to move horizontally.

[0077] Furthermore, a plurality of partitions 42 are spaced apart from each other and product channels 46 are formed between adjacent partitions 42. Figure 15As shown, in this embodiment, there are four product channels. The product conveying mechanism 3 includes a plurality of conveying channels 31 separated by spacers 32. There are also four conveying channels 31, and the product channels 46 interface with corresponding conveying channels 31. That is, canned or bottled products enter the product channels 46 from the conveying channels 31. In this embodiment, each product channel 46 can hold three products, for a total of 12 products.

[0078] Reference Figure 14 As shown, multiple support rods 43 are arranged at intervals in front and back, and a can dropping channel 431 for products to fall is formed between two adjacent support rods 43. The partition 42 has a first position and a second position. In the first position, the can dropping channel 431 and the product channel 46 are staggered, and the support rods 43 are located between adjacent partitions 42; in the second position, the can dropping channel 431 is directly below the product channel 46.

When the can dropping plate 44 is in the second position, the second through hole 451 and the first through hole are aligned with each other.

[0081] This embodiment also provides a method for loading a tray for a filled or bottled product, comprising the following steps:

[0082] (1) The empty conveying station 21 moves to the bottom of the tray module 1;

[0083] (2) A stack of pallets is placed in the tray separation module 1. The upper pallet 14 and the lower pallet 13 move inward and are inserted between the two pallets on the bottom layer. The upper pallet 14 moves upward and lifts the pallets except the pallet on the bottom layer. At the same time, the lower pallet 13 presses the edge of the pallet on the bottom layer, separating the pallet on the bottom layer from the other pallets and dropping it into the conveying station 21 below.

[0084] (3) The conveying station 21 carries the tray and moves to the bottom of the machine head 4;

[0085] (4) The product conveying mechanism 3 delivers the filled or bottled products in batches to the die head 4, and the die head 4 positions the multiple filled or bottled products and drops them into the tray;

[0086] (5) The conveying station 21 carries the tray loaded with products to the unloading mechanism 5, and the unloading mechanism 5 unloads the products.

[0087] Specifically, in step (4), the product conveying mechanism 3 diverts the product to multiple conveying channels 31 through multiple spacers 32. The partitions 42 of the die head 4 are moved by the first cylinder 47 so that the product channels 46 formed between the partitions 42 are connected to the corresponding conveying channels 31. At this time, the support rods 43 are located below the product channels 46 to receive the products. The can drop channels 431 and the product channels 46 are staggered, and the support rods 43 are located between adjacent partitions 42.

[0088] After a predetermined number of products enter each product channel 46, the partition 42 is moved so that the support rod 43 avoids the bottom of the product channel 46. The partition 42 is located in the second position, and the can drop channel 431 between the product channel 46 and the support rod 43 is aligned in the vertical direction. The products fall onto the positioning plate 45 of the machine head 4; at this time, the positioning plate 45 is carried upward by the can drop plate 44 to the bottom of the support rod 43. The second through hole 451 on the positioning plate 45 is opposite to the bottom of the can drop channel 431. The products fall into the second through hole 451 through the positioning guide columns 452 around the second through hole 451. The first through hole 441 and the second through hole 451 on the can drop plate 44 of the machine head 4 are staggered with each other.

[0089] Finally, the second cylinder 48 is used to move the can drop plate 44 carrying the positioning plate 45 downward to the top of the pallet, and the third cylinder 49 is used to move the positioning plate 45 horizontally so that the first through hole and the second through hole 451 are aligned, and the product falls into the pallet below the can drop plate 44.

[0090] The pallet loading machine of this embodiment only requires one operator to place a stack of pallets in the material discharge space, and the rest of the work can be completed automatically. The degree of automation is high, which improves production efficiency and capacity.

[0091] When the product is loaded on a tray, the conveying station 21 first moves to the bottom of the tray sub-module 1, and the upper card plate 13 and the lower card plate 14 in the tray sub-module 1 separate the bottom tray from the other trays, and the bottom tray falls into the conveying station 21 below; then, the conveying station 21 moves with the tray to the bottom of the machine head 4, and the product conveying mechanism 3 delivers the product to the product channel 46. The can drop channel 431 and the product channel 46 are staggered, and the support rod 43 is located between the adjacent partitions 42 to receive the product 100. After all the products 100 enter the product channel 46, the partition 42 is moved so that the product channel 46 and the can drop channel 431 are aligned in the vertical direction. Under the action of the second cylinder 48, the can drop plate 431 is moved. 31 moves upward, and the positioning plate 45 is carried by the can-dropping plate 431 to move upward to the bottom of the support rod 43. The second through hole 451 on the positioning plate 45 is opposite to the bottom of the can-dropping channel 431. The positioning guide slope 4521 is used to make multiple products 100 fall into the second through hole 451. Finally, the can-dropping plate 431 is driven downward by the second cylinder 48 again, and the positioning plate 45 moves downward with the can-dropping plate 431 to the top of the tray. The positioning plate 45 is moved horizontally by the third cylinder 49, and the first through hole and the second through hole 451 are aligned. The product 100 falls into the tray, and the conveying station 21 carries the tray to the unloading mechanism 5, and the unloading mechanism 5 (such as a robot or a conveyor belt, etc.) is used to unload the product.
