[0035] During the production process of small boxes such as cigarette boxes and tea boxes, due to the large quantity, it is not suitable to use the method of single picking by a manipulator to achieve the stacking of box bodies. For small objects such as formed box blanks and rectangular molds in the production workshop of small box packaging, a relatively large degree of manual participation is still required during the collection and transportation process. Therefore, it is necessary to develop a palletizer with a relatively high degree of automation and capable of improving production efficiency to meet the needs of stacking materials such as cigarette boxes, tea boxes, premium gift boxes, as well as block semi-finished products and molds during the workshop production process.

[0036] To solve the above problems, the present invention proposes a palletizer. Please refer to Figures 1-6, which is an embodiment of the palletizing machine proposed by the present invention. In this embodiment, the palletizing machine includes a frame 1, a sorting device, and a blanking device. On the frame 1, a feeding station 11, a palletizing station 12, and a blanking station 13 are sequentially formed. The feeding station 11 is used to supply a plurality of molds 5 to be arranged in sequence along the front-back direction of the frame 1 to form a mold queue 51. The feeding station 11 and the palletizing station 12 are arranged at intervals along the left-right direction of the frame 1, and the palletizing station 12 and the blanking station 13 are arranged at intervals along the up-down direction of the frame 1. The sorting device is arranged on the frame 1 and is used to move the mold queue 51 from the feeding station 11 to the palletizing station 12. The blanking device is arranged on the frame 1 and is used to move the mold queue 51 from the palletizing station 12 to the blanking station 13.

[0037] Please refer to Figure 1 , on the frame 1 of the palletizing machine proposed by the present invention, a feeding station 11 is provided. At the feeding station 11, a plurality of molds 5 are arranged in sequence along the front-back direction of the frame 1 to form a mold queue 51. The molds 5 can be arranged to form the mold queue 51 through a conveyor belt 3, a manipulator, or other means. Then, the sorting device moves the mold queue 51 to the palletizing station 12, and the blanking device transfers the mold queue 51 at the palletizing station 12 to the blanking station 13. Its moving method can be determined according to the structure of the frame 1 and the actual processing production process. Specifically, in this embodiment, the blanking device is transferred by a lifting movement method. The space below the palletizing station 12 is the blanking station 13. During the process of removing the mold queue 51 at the palletizing station 12, the sorting device can repeat the movement to stack a plurality of mold queues 51 from bottom to top at the palletizing station 12, and then make a plurality of mold queues 51 located in the blanking station 13 at the same time. In this way, the degree of automation is high and the efficiency is high. Of course, in other embodiments, if the blanking device is transferred by other movement methods, the sorting device can also move only one mold queue 51 each time. The palletizing machine proposed by the present invention palletizes the molds 5 in the form of a mold queue 51, with high working efficiency and high degree of automation. Its mold queue 51 is also palletized by stacking, further improving the working efficiency.

[0038] Further, the palletizing machine further includes a conveyor belt 3 for carrying a plurality of molds 5. The conveyor belt 3 has a moving stroke along the front-back direction to drive a plurality of molds 5 to reach the feeding station 11 in sequence and form a mold queue 51.

[0039] Please refer to Figures 1-6 , the palletizing machine of the present invention conveys a plurality of molds 5 in the form of a conveyor belt 3, which is easy to control the conveying speed and the conveying quantity, and at the same time can also simplify the moving stroke of the sorting device.

[0040] Furthermore, the distribution device includes a distribution plate 2 , which is movably installed at the loading station 11 and has a movable stroke along the left and right directions. The distribution plate 2 is used to push the mold queue 51 to the stacking station 12 .

[0041] The palletizer of the present invention moves the mold queue 51 through the distribution plate 2. Its structure is simple and effective, and it is not easy to interfere with the conveyor belt 3 or other devices. Figure 1 The palletizer also includes a linear cylinder for driving the distribution plate 2. The linear cylinder is connected to the right end surface of the distribution plate 2. The linear cylinder can effectively control the movement accuracy of the distribution plate 2 and its shifting working cycle.

[0042] Furthermore, a conveyor belt baffle 31 is provided on the left side of the conveyor belt 3, which can play a role of limiting when the distribution plate 2 moves along the left direction of the frame 1 to the loading station 11.

[0043] Furthermore, the front end of the distribution plate 2 protrudes toward the right side of the frame 1 to form a front baffle 22, and the front baffle 22 is used to limit the multiple molds 5 from escaping the loading station 11 forward. The rear end of the distribution plate 2 protrudes toward the left side of the frame 1 to form a rear baffle 21. The rear baffle 21 is used to limit the mold 5 located behind the loading station 11 from entering the loading station 11 when the distribution plate 2 moves to the stacking station 12.

[0044] The front baffle 22 of the distribution plate 2 can effectively limit the multiple molds 5 from escaping forward from the loading station 11. Since the distribution plate 2 is moved very quickly, in this embodiment, when the distribution plate 2 is moved, the conveyor belt 3 keeps running. In order to further ensure that the number of molds 5 moved each time is consistent and that the molds 5 that have not reached the loading station 11 collide with the molds 5 at the loading station 11, the distribution plate 2 is also provided with a rear baffle 21 to cut off the multiple molds 5 on the conveyor belt 3. Accordingly, the conveyor belt baffle 31 is provided with a notch 32 for the rear baffle 21 to pass through.

[0045] In this embodiment, the palletizer is provided with a plurality of position sensors for detecting whether the mold 5 is in place. Figure 1 Taking the rear baffle position sensor 33 in the figure as an example, when it detects that the mold 5 has entered the loading station 11 and has reached the correct position, it sends a signal that the distribution plate 2 can be distributed, and then the distribution plate 2 performs a shifting action to ensure that the number of molds 5 shifted each time is consistent. Obviously, a better embodiment is that a position sensor is also provided at the front baffle 22, so that the distribution plate 2 can accurately switch positions between the loading station 11 and the stacking station 12.

[0046] Further, the blanking device includes a lifting mechanism. The lifting mechanism includes a palletizing plate 61 installed at the palletizing station 12. The palletizing plate 61 has an up-and-down movement stroke along the rack 1. The palletizing plate 61 is used to stack a plurality of mold queues 51 sorted by the sorting plate 2 from bottom to top in sequence, so that the mold queue 51 at the uppermost position is at the same height as the feeding station 11.

[0047] Specifically, when the sorting plate 2 deflects a mold queue 51 onto the palletizing plate 61, the palletizing plate 61 descends by a height value of one mold 5. At this time, the height of the mold queue 51 is consistent with the height of the feeding station 11. The sorting plate 2 can continue to deflect the next mold queue 51, and then the palletizing plate 61 continues to descend by a height value of one mold 5. This cycle continues. Finally, when the palletizing plate 61 descends to the lowest position, the palletizing plate 61 carries a large number of mold queues 51 in a stacked manner, greatly improving the work efficiency.

[0048] Further, please refer to Figures 2-4 , the lifting mechanism further includes a palletizing fence arranged along the circumference of the palletizing plate 61 to jointly define a palletizing groove with the palletizing plate 61. An inlet for the mold queue 51 is provided on one side of the palletizing groove close to the sorting plate 2. The palletizing fence can ensure that when the sorting plate 2 deflects the mold queue 51, the position of the mold queue 51 does not exceed the palletizing station 12, thereby ensuring the neatness and accuracy of palletizing. In this embodiment, the palletizing fence includes a right fence plate 62, a front fence plate 63, and a rear fence plate 64.

[0049] Further, on both sides of the palletizing fence connected to the inlet, guiding inclined surfaces 63a inclined inward are provided at the inlet to prevent the mold 5 from colliding with the equipment and being damaged. Please refer to Figure 3 , which is an embodiment of the guiding inclined surface 63a of the front fence plate 53.

[0050] Further, the rack 1 is provided with a storage area 14 for storing a plurality of mold queues 51. The storage area 14 is arranged at the front side of the lifting mechanism for the forklift board 8 to enter the storage area 14 to remove the mold queue 51. The palletizing machine further includes a pushing plate 77. The pushing plate 77 is movably installed below the conveyor belt 3 and has a left-right movement stroke. The pushing plate 77 is used to push the mold queue 51 from the blanking station 13 to the storage area 14.

[0051] In this embodiment, in order to further improve the palletizing efficiency and the number of palletized items, the rack 1 is also provided with a storage area 14 to store a large number of mold queues 51, so that the forklift board 8 can remove them all at once. Specifically, when the palletizing plate 61 descends to the lowest position, it is pushed into the storage area 14, that is, onto the forklift board 8, by the pushing plate 77, which is highly efficient and can ensure the neatness of a plurality of mold queues 51 at the same time.

[0052] Further, please refer toFigure 1 Moreover, the rack 1 is further provided with two guiding and limiting plates 4 located in the storage area 14. The two guiding and limiting plates 4 are respectively arranged on the left and right sides of the storage area 14 and have a movable stroke in the front-back direction. When the pushing plate 77 pushes the die queue 51 to the storage area 14, the two guiding and limiting plates 4 move towards the die queue 51 and respectively abut against the front and rear ends of the die queue 51.

[0053] When stacking the die queue 51, there may still be offset. In order to rectify the offset, two guiding and limiting plates 4 are provided, which are distributed on the left and right sides of the storage area 14. The two guiding and limiting plates 4 move towards each other to pat and rectify the die queue 51, maintaining the neatness of the stacking.

[0054] Furthermore, please refer to Figure 6 Moreover, the rack 1 is further provided with two forklift plate guiding blocks 9, which are respectively arranged on the front and rear sides of the storage area 14 to jointly limit the front and rear sides of the forklift plate 8. Among them, the side wall of each forklift plate guiding block 9 abutting against the forklift plate 8 is arc-shaped to form a guiding arc surface 91 inclined to the right of the rack 1, facilitating the alignment of the forklift plate 8, so that the staff can quickly and accurately extend the forklift plate 8 into the storage area 14, further improving the work efficiency.

[0055] Furthermore, please refer to Figure 6 Moreover, the rack 1 is further provided with a forklift plate baffle 81, which is arranged on the right side of the stacking area to limit the forklift plate 8 and prevent it from colliding with the equipment.

[0056] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
