Description

Technical Field

[0001] The present invention relates to the field of product packaging, and particularly to a double - outlet stacking machine with buffer fins. Background Art

[0002] During the production process of products such as diapers, generally, manual labor is used to put stacks of diapers into packaging bags. In existing stacking machines, there is generally a straight conveyor line with one inlet and one outlet. The products after stacking are conveyed to the outlet through a conveyor belt, and the operator places the stacked products into the packaging bag at the outlet. The production efficiency of this stacking machine is low. Summary of the Invention

[0003] The purpose of the present invention is to provide a double - outlet stacking machine with buffer fins to improve production efficiency.

[0004] To solve the above - mentioned technical problems, an embodiment of the present invention provides a double - outlet stacking machine with buffer fins, including:

[0005] A frame;

[0006] A chain conveyor line, which is looped around the frame. The chain conveyor line has a plurality of fins, and adjacent fins are used to clamp products;

[0007] A first driving component and a second driving component, both of which are arranged on the frame and are used to drive the chain conveyor line to convey products; when the chain conveyor line conveys products, the first driving component and the second driving component are also respectively used to give the chain conveyor line the conveying power in opposite directions to make the chain conveyor line relatively stationary;

[0008] A first pushing device and a second pushing device, which are arranged on different sides of the frame and are used to push out products in different areas of the chain conveyor line;

[0009] A first buffer driving component, which is arranged on the frame and is used to drive the area of the chain conveyor line adjacent to the first pushing device to move relative to the first pushing device and is used to tighten the chain of the chain conveyor line;

[0010] A second buffer driving component, which is arranged on the frame and is used to drive the area of the chain conveyor line adjacent to the second pushing device to move relative to the second pushing device and is used to tighten the chain of the chain conveyor line.

[0011] In the embodiment of the present invention, compared with the prior art, through the chain conveyor line arranged around the frame, a first pushing device and a second pushing device are arranged on different sides of the frame. The first pushing device and the second pushing device can respectively push the products on the corresponding chain conveyor line into the packaging bag, that is, the stacker has two product outlets, thereby improving the production effect. In addition, a first driving component and a second driving component are provided to drive the chain conveyor line. When the chain conveyor line transports the products to a suitable position where they can be pushed out by the first pushing device and the second pushing device, the first driving component and the second driving component are controlled to make the chain conveyor line receive driving forces in opposite directions at the same time, so that the chain conveyor line is relatively stationary, and the products on the chain conveyor line in the corresponding area can be pushed out in cooperation with the first pushing device and the second device. At the same time, when the chain conveyor line is made relatively stationary by the first driving component and the second driving component, the chains on the chain conveyor line will be slightly slack. At this time, the areas of the chain conveyor line corresponding to the first pushing device and the second pushing device where the products can be pushed out will also shift, so that the products cannot be pushed out. However, by setting the first buffer driving component and the second buffer driving component to move the chain conveyor line, the chains can be tightened, so that the areas of the chain conveyor line where the products need to be pushed out correspond to the first pushing device and the second pushing device, realizing the smooth pushing out of the products by the first pushing device and the second pushing device.

[0042] Embodiments of the present invention will be described below with reference to the drawings.

[0043] One embodiment of the present invention relates to a double - outlet buffer vane stacker 100. As Figure 1 and Figure 2As shown in the figure, the double - outlet buffer - equipped fin stacker 100 includes: a frame 1, a chain conveyor 2, a first driving assembly 5, a second driving assembly 6, a first pushing device 7, a second pushing device 8, a first buffer driving assembly 3, and a second buffer driving assembly 4. The chain conveyor 2 is looped around the frame 1. The chain conveyor 2 has a plurality of fins 20, and products 200 are clamped between two adjacent fins 20. The first driving assembly 5 and the second driving assembly 6 are both arranged on the frame 1 and are used to drive the chain conveyor 2 to convey the products 200. A plurality of fins 20 are arranged along the direction of the chain conveyor 2, and the products 200 are clamped between two adjacent fins 20. When the chain conveyor 2 conveys the products 200, the first driving assembly 5 and the second driving assembly 6 are also respectively used to give the chain conveyor 2 the conveying power in opposite directions, making the chain conveyor 2 relatively stationary. The first pushing device 7 and the second pushing device 8 are arranged on different sides of the frame 1 and are used to push out the products 200 in different areas of the chain conveyor 2. The first buffer driving assembly 3 is arranged on the frame 1 and is used to drive the area of the chain conveyor 2 adjacent to the first pushing device 7 to move relative to the first pushing device 7 and is used to tighten the chain of the chain conveyor 2. The second buffer driving assembly 4 is arranged on the frame 1 and is used to drive the area of the chain conveyor 2 adjacent to the second pushing device 8 to move relative to the second pushing device 8 and is used to tighten the chain of the chain conveyor 2. The products 200 can be, for example, diapers, sanitary pads, etc. The first pushing device 7 corresponds to one outlet on the chain conveyor 2, and the second pushing device 8 corresponds to the other outlet on the chain conveyor 2.

[0044] Specifically, the first driving assembly 5 includes a motor and transmission parts. The transmission parts can include gears, etc. By driving the transmission parts with the motor, the transmission parts drive the chain of the chain conveyor 2 to rotate, thereby making the conveyor belt connected to the chain move. The structure of the second driving assembly 6 can be similar to that of the first driving assembly 5, and will not be elaborated here. In this example, by making the motors of the first driving assembly 5 and the second driving assembly 6 rotate in opposite directions, the chain conveyor 2 is made almost stationary. Among them, the motor of the first driving assembly 5 can rotate reversely while the motor of the second driving assembly 6 rotates forward; or the motor of the first driving assembly 5 can rotate forward while the motor of the second driving assembly 6 rotates reversely.

[0045] Through the chain conveyor line 2 looped around the frame 1, a first pushing device 7 and a second pushing device 8 are arranged on different sides of the frame 1. The first pushing device 7 and the second pushing device 8 can respectively push the products 200 on the corresponding chain conveyor line 2 into the packaging bags. That is, the stacker has two product 200 outlets, thereby improving the production effect. In addition, a first driving component 5 and a second driving component 6 are provided to drive the chain conveyor line 2. When the chain conveyor line 2 conveys the product 200 to a suitable position where it can be pushed out by the first pushing device 7 and the second pushing device 8, the first driving component 5 and the second driving component 6 are controlled to make the chain conveyor line 2 receive driving forces in opposite directions simultaneously, so that the chain conveyor line 2 is relatively stationary, and it can cooperate with the first pushing device 7 and the second device to push the product 200 on the chain conveyor line 2 in the corresponding area. At the same time, when the chain conveyor line 2 is made relatively stationary by the first driving component 5 and the second driving component 6, the chain on the chain conveyor line 2 will be slightly slack. At this time, the area of the chain conveyor line 2 corresponding to the first pushing device 7 and the second pushing device 8 where the product 200 can be pushed out will also shift, so that the product 200 cannot be pushed out. However, by setting the first buffer driving component 3 and the second buffer driving component 4 to move the chain conveyor line 2, the chain can be tightened, so that the area of the chain conveyor line 2 where the product 200 needs to be pushed out corresponds to the first pushing device 7 and the second pushing device 8, realizing the smooth pushing out of the product 200 by the first pushing device 7 and the second pushing device 8.

[0046] Further, in the circumferential direction of the frame 1, there are successively an inlet area, a first buffer area, a first pushing area, a second buffer area, and a second pushing area. As Figure 1 , Figure 2 shown, along the conveying direction of the chain conveyor line 2, the parts of the chain conveyor line 2 located in the inlet area, the first buffer area, the first pushing area, the second buffer area, and the second pushing area are successively the film inlet 21, the first buffer section 22, the first pushing section 23, the second buffer section 24, and the second pushing section 25. That is to say, the part of the chain conveyor line 2 transmitted to the inlet area is the film inlet 21, the part of the first buffer area is the first buffer section 22, the part of the first pushing area is the first pushing section 23, the part of the second buffer area is the second buffer section 24, and the part of the second pushing area is the second pushing section 25. The first buffer section 22 is adjacent to the first pushing section 23, and the first pushing device 7 is used to push the product 200 on the first pushing section 23. The second buffer section 24 is adjacent to the second pushing section 25, and the second pushing device 8 is used to push the product 200 on the second pushing section 25. The structures of the first pushing device 7 and the second pushing device 8 are substantially the same, and the corresponding areas of the first pushing device 7 and the second pushing device 8 are both the outlets of the chain conveyor line 2. Taking the first pushing device 7 as an example Figure 5The first pushing device 7 includes: a support frame 71 fixed to the machine frame 1, a pushing motor 72 arranged on the support frame 71, a conveyor belt 73 driven by the pushing motor 72, a guide rail 74 extending along the extending direction of the conveyor belt 73, a fixed block 75 fixed on the conveyor belt 73, and a pushing arm 76 movably connected to the fixed block 75. The fixed block 75 is slidably connected to the guide rail 74. The conveyor belt 73 drives the fixed block 75 to move along the guide rail 74, and the fixed block 75 drives the pushing arm 76 to move. The pushing arm 76 has a plurality of pushing teeth, and one pushing tooth is inserted between two fins 20 to push the product 200 away from the fins 20. The first pushing device 7 further includes a rotating motor 77 for driving the pushing arm 76 to rotate, so that the pushing arm can be lifted or lowered.

[0047] In addition, as Figure 1 , Figure 2 shown, the first buffer drive assembly 3 and the second buffer drive assembly 4 are arranged on different sides of the machine frame 1.

[0048] In addition, as Figure 1 , Figure 2 shown, the machine frame 1 has a first installation side 11, a second installation side 12, a third installation side 13 and a fourth installation side 14 connected in sequence, wherein the first installation side 11 and the third installation side 13 are arranged opposite to each other, and the second installation side 12 and the fourth installation side 14 are arranged opposite to each other. The chain conveyor line 2 has a first conveying section located on the first installation side 11, a second conveying section located on the second installation side 12, a third conveying section located on the third installation side 13, and a fourth conveying section located on the fourth installation side 14. The first pushing device 7 is arranged on the first installation side 11, and the second pushing device 8 is arranged on the second installation side 12. The first buffer drive assembly 3 includes: a first buffer motor 31, a first pulley group 32, a first track 33, and a first sprocket group 34. The first track 33 extends along the extending direction of the first conveying section, and the first buffer motor 31 is used for driving the first pulley group 32 to drive along the extending direction of the first conveying section; the first sprocket group 34 is fixedly connected to the first base 26 of the chain conveyor line 2 and meshes with the chain 27 of the chain conveyor line 2. The first sprocket group 34 is slidably arranged on the first track 33. When the first pulley group 32 drives, it drives the first sprocket group 34 to slide along the first track 33. When the first sprocket group 34 slides along the first track 33, it drives the first base 26 of the chain conveyor line 2 to move, so as to drive the chain 27 of the stretching chain conveyor line 2. Specifically, the rotation of the main shaft of the first buffer motor 31 drives the driving wheel 322 of the first pulley group 32 to rotate. The driving wheel 322 drives the conveyor belt 321 of the first pulley group 32 to drive. The conveyor belt 321 drives the first sprocket group 34 to move along the first track 33. Thus, the first sprocket group 34 drives the chain 27 of the chain conveyor line 2 to move together, so that the chain 27 of the chain conveyor line 2 can be tightened, and the product 200 on the chain conveyor line 2 can be moved to the position of the first pushing device 7 and be accurately pushed out.

[0049] Further, as shown in Figure 1 and Figure 3 , the first sprocket set 34 includes: a first main sprocket 341 and a first mounting base 342 connecting the first main sprocket 341. The first mounting base 342 is slidably connected to the first track 33. The bottom of the first mounting base 342 has a first fixing block 3411 fixed to the conveyor belt 321 of the first pulley set 32. Thus, the conveyor belt drive can drive the first mounting base 342, which can drive the first sprocket set 34. The first buffer drive assembly 3 further includes: a first auxiliary sprocket 35, which is mounted on the frame 1. The first auxiliary sprocket 35 is spaced apart from the first main sprocket 341 along the extension direction of the second conveying section. The first main sprocket 341 is located at the corner of the first conveying section and the second conveying section.

[0050] In addition, as shown in Figure 1 and Figure 3 , the first buffer drive assembly 3 further includes: a first auxiliary track 36, and a first roller 37 fixed to the first base 26. The first roller 37 is operably rolled along the first auxiliary track 36. And the first roller 37 is arranged on the second conveying section. The distance between the first roller 37 and the first main sprocket 341 is less than the distance between the first roller 37 and the first auxiliary sprocket 35.

[0051] Further, as shown in Figure 1 and Figure 3 , the first auxiliary track 36 extends towards the fourth conveying section and bends towards the third conveying section.

[0052] In addition, as shown in Figure 1 and Figure 4 , the second buffer drive assembly 4 includes: a second buffer motor 41, a second pulley set 42, a second track 43, and a second sprocket set 44. The second track 43 extends along the extension direction of the fourth conveying section. The second buffer motor 41 is used to drive the second pulley set 42 to drive along the extension direction of the fourth conveying section. The second sprocket set 44 is fixedly connected to the second base of the chain conveyor line 2 and meshes with the chain 27 of the chain conveyor line 2. The second sprocket set 44 is slidably arranged on the second track 43. When the second pulley set 42 drives, it drives the second sprocket set 44 to slide along the second track 43. When the second sprocket set 44 slides along the second track 43, it drives the second base of the chain conveyor line 2 to move. The structure and working principle of the second buffer drive assembly 4 are basically the same as those of the first buffer drive assembly 3, and will not be repeated here.

[0053] In addition, as shown in Figure 1 and Figure 4As shown, the second sprocket set 44 includes: a second main sprocket 441 and a second mounting seat 442 connecting the second main sprocket 441. The second mounting seat 442 is slidably connected to the second track 43. The second buffer driving assembly 4 further includes: a second auxiliary sprocket 45. The second auxiliary sprocket 45 is mounted on the frame 1. The second auxiliary sprocket 45 is spaced apart from the second main sprocket 441 along the extending direction of the third conveying section. The second main sprocket 441 is located at the corner of the third conveying section and the fourth conveying section. The structure and working principle of the second buffer driving assembly 4 are basically the same as those of the first buffer driving assembly 3, and will not be repeated here.

[0054] Further, as Figure 1 、 Figure 4 shown, the second buffer driving assembly 4 further includes: a second auxiliary track 46, and a second roller 47 fixed to the second base. The second roller 47 is operably rolled along the second auxiliary track 46. And the second roller 47 is arranged on the third conveying section. The distance between the second roller 47 and the second main sprocket 441 is less than the distance between the second roller 47 and the second auxiliary sprocket 45. The second auxiliary track 46 extends toward the third mounting side 13 and bends toward the second conveying section. The structure and working principle of the second buffer driving assembly 4 are basically the same as those of the first buffer driving assembly 3, and will not be repeated here.
