Description

Technical Field

[0001] The utility model relates to the technical field of logistics transmission equipment, in particular to a palletizing and stacking device based on chain transmission. Background Art

[0002] A palletizer automatically stacks cartons packed into containers onto pallets and pallets in a specific arrangement. It can stack multiple layers and then push them out for forklift transportation to the warehouse for storage. A palletizer automatically stacks bags, cartons, or other packaging materials delivered by a conveyor into stacks according to the customer's process requirements and then transports the stacked materials. A palletizer is a machine used in conjunction with a palletizer. The palletizer is a mechanism that supplies pallets for goods during production. Pallets are needed to stack goods for easy transportation and packaging. The palletizer can continuously and orderly supply pallets based on the needs of the goods, without the need for manual labor. The pallets are uniformly and promptly supplied, improving production efficiency.

[0003] Given the low dimensional accuracy of pallets, pallets typically wear out during repeated use, causing variations in the height of stacked pallets. Consequently, height errors can occur after long-term use, preventing the traversing mechanism from entering the pallet openings and triggering fault alarms. While using a motor-driven screw mechanism to lift the traversing mechanism can mitigate height variations, ensuring accuracy and reducing failure rates, it occupies a significant amount of floor space, resulting in excessive overhang at the bottom of the pallet crane and reduced pallet storage space.

DETAILED DESCRIPTION

[0032] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiment of the present utility model: Figure 1-Figure 3 As shown, the utility model proposes a stacking and supplying device based on chain transmission, including a main frame 1, a pallet output line 2, a traverse assembly 3 and a chain lifting assembly 4; the main frame 1 is mainly used to support and fix the entire stacking device, and its inner side wall has a pallet positioning function. Specifically, a pallet positioning surface 11 is provided on the inner side wall of the main frame 1. The pallet positioning surface 11 is vertically arranged. There are multiple pallet positioning surfaces 11, and multiple pallet positioning surfaces 11 can be arranged on adjacent and opposite sides of the main frame 1. The pallets are positioned by the pallet positioning surfaces 11, so that the pallets can be placed in the main frame 1 neatly in sequence, which is convenient for subsequent operations.

[0034] The pallet output line 2 is arranged below the main frame 1 and is used to transport the pallets out of the stacking device;

[0035] There are two traverse assemblies 3, which are symmetrically arranged on both sides of the main frame 1. The traverse assemblies 3 can move up and down along the main frame 1; the traverse assembly 3 is mainly used to support the second pallet from the bottom to the top, thereby supporting the entire stack of pallets, thereby separating from the first pallet and allowing it to remain on the pallet output line 2.

[0036] The chain lift assembly 4 is connected to the traverse assembly 3 and can drive the traverse assembly 3 up and down along the main frame 1. The chain lift assembly 4 mainly drives the left and right traverse assemblies 3 to the appropriate position, completing the two actions of lifting the second pallet to the upper stack of pallets and dropping them onto the pallet output line 2.

[0037] See Figure 4-Figure 5 As shown, as an implementation method, the traverse assembly 3 includes a base 31, two struts 32, and a telescopic mechanism 33. The base 31 is slidably connected to the main frame 1. The chain lifting assembly 4 is fixedly connected to the base 31. The two struts 32 are slidably mounted on the base 31 and arranged in parallel. Specifically, two guide rails 37 can be fixedly mounted on the base 31, and sliders that slide with the guide rails 37 can be installed on the guide rails 37, and the two struts 32 are fixedly connected to the two sliders. The struts 32 can be plates with a U-shaped cross-section, with the openings of the U-shaped plates facing the corresponding guide rails 37. The struts 32 are located above the pallet output line 2. The ends of the two struts 32 away from the main frame 1 are fixedly connected by a connecting plate 34. The telescopic mechanism 33 is fixedly mounted on the base 31 via a mounting base, and the telescopic end of the telescopic mechanism 33 is fixedly connected to the connecting plate 34 by welding or bolting. The telescopic mechanism 33 can be a hydraulic cylinder, a pneumatic cylinder, etc. The telescopic mechanism 33 drives the support rod 32 to move, so that the support rod 32 extends into the side opening of the pallet, and then the chain lifting assembly 4 drives the traverse assembly 3 to move upward to lift the pallet.

[0038] In order to reduce the space occupied by the traverse assembly 3 , the telescopic mechanism 33 and the support rod 32 may be arranged on the same side of the connecting plate 34 .

[0039] Description of the usage process: First, manually use a forklift or lift to place the standard-sized pallets into the main frame 1 in order, and the entire stack of pallets falls on the pallet output line 2. Then start the chain lifting assembly 4 to make the two traverse assemblies 3 rise upward to the side opening position of the second pallet from the bottom up. After that, the traverse assembly 3 extends the support rod 32 into the side opening of the pallet. At this time, the chain lifting assembly 4 is started again to lift the second and above stacks of pallets upward, leaving only the first pallet on the pallet output line 2. Then the pallet output line 2 transports the pallet out of the stacking device. After the pallet is sent out, the chain lifting assembly 4 drops the entire pallet onto the pallet output line 2, and then repeats the previous action, thereby achieving the purpose of automatically sending pallets.

[0040] See Figure 1 As an implementation method, the chain lifting assembly 4 includes a first sprocket 41, a second sprocket 42, a first chain 43 and a transmission motor 44;

[0041] A first sprocket 41 is rotatably mounted on the bottom of the main frame 1; a second sprocket 42 is rotatably mounted on the top of the main frame 1; a first chain 43 is drivingly connected to the first sprocket 41 and the second sprocket 42; the first chain 43 is fixedly connected to the base 31; and a transmission motor 44 is drivingly connected to the second sprocket 42. In actual application, the two second sprockets 42 can be fixedly connected via a rotating shaft 8, a third sprocket 9 is disposed on the rotating shaft 8, the output shaft of the transmission motor 44 is fixedly connected to a fourth sprocket 10, the third sprocket 9 and the fourth sprocket 10 are drivingly connected via a second chain 12, and the transmission motor 44 is fixedly mounted on the main frame 1.

[0042] See Figure 4-Figure 6 As shown, in order to prevent the traverse assembly 3 from tilting during the up and down movement, which may cause the pallet to fall, the following measures are adopted: two sliders 35 are fixedly installed on the side of the base 31 close to the main frame 1 by screws, and the two sliders 35 are respectively located on both sides of the telescopic mechanism 33; a slide rail 5 that cooperates with the slider 35 is fixedly installed on the main frame 1, and the slide rail 5 is vertically arranged. Through the cooperation between the slider 35 and the slide rail 5, the traverse assembly 3 can be effectively prevented from tilting during the up and down movement.

[0043] To facilitate the installation of the traverse assembly 3 on the chain lifting assembly 4, a mounting bracket 36 is fixedly mounted on the side of the base 31 near the main frame 1 by welding. The mounting bracket 36 can be a rectangular frame and is arranged perpendicular to the base 31. The telescopic mechanism 33 passes through the mounting bracket 36. The upper crossbar of the mounting bracket 36 has a first threaded hole 361, and the lower crossbar of the mounting bracket 36 has a second threaded hole 362. The center lines of the first threaded hole 361 and the second threaded hole 362 coincide. The two ends of the first chain 43 are respectively threadedly connected to the first threaded hole 361 and the second threaded hole 362 by bolts 6. Specifically, the first chain 43 of the circular chain is disconnected, and a bolt 6 is rotated and installed at each end of the first chain 43. By threading the two bolts 6 into the first threaded hole 361 and the second threaded hole 362, the traverse assembly 3 is fixed to the first chain 43.

[0044] In order to avoid injury to the staff during the up and down movement of the traverse assembly 3, the following measures are adopted: Figure 1 、 Figure 2 、 Figure 7 As shown, it also includes two protection frames 7, which are respectively corresponding to the two traversing assemblies 3. The protection frames 7 are fixedly connected to the main frame 1, and the traversing assemblies 3 are located in the protection frames 7.

The above are only preferred embodiments of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
