Description

Technical Field

[0001] This utility model relates to the field of product packaging, and in particular to a dual-outlet stacker with buffered feathers. Background Technology

[0002] In the production of products such as diapers, stacked diapers are typically placed into packaging bags manually. Existing stacker cranes are generally linear conveyor lines with one inlet and one outlet. Products are transported by a conveyor belt to the outlet, where operators place the stacked products into packaging bags. This type of stacker crane has low production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a dual-outlet stacker with buffered feathers, thereby improving production efficiency.

[0004] To solve the above-mentioned technical problems, embodiments of this utility model provide a dual-outlet stacker with buffered feathers, comprising:

[0005] frame;

[0006] A chain conveyor line is arranged around the frame, and the chain conveyor line has multiple blades, with products clamped between two adjacent blades;

[0007] The first drive assembly and the second drive assembly are both mounted on the frame and are used to drive the chain conveyor line to transport products. When the chain conveyor line is transporting products, the first drive assembly and the second drive assembly are also used to provide the chain conveyor line with power in opposite directions, so that the chain conveyor line is relatively stationary.

[0008] The first ejection device and the second ejection device are located on different sides of the frame and are used to eject products from different areas of the chain conveyor line.

[0009] A first buffer drive assembly is disposed on the frame for driving the area of ​​the chain conveyor adjacent to the first ejection device to move relative to the first ejection device, and for tensioning the chain of the chain conveyor.

[0010] A second buffer drive assembly, disposed on the frame, is used to drive the area of ​​the chain conveyor adjacent to the second ejector to move relative to the second ejector, and to tension the chain of the chain conveyor.

[0011] Compared to existing technologies, this embodiment of the invention utilizes a chain conveyor line encircling the frame, with a first ejector device and a second ejector device positioned on different sides of the frame. These devices eject products from their respective chain conveyor lines and place them into packaging bags, effectively giving the stacker crane two product outlets and improving production efficiency. Furthermore, a first drive assembly and a second drive assembly drive the chain conveyor line. When products are conveyed to a suitable position to be ejected by the first and second ejector devices, the first and second drive assemblies are controlled to apply opposing driving forces to the chain conveyor line simultaneously, keeping it relatively stationary. This allows the first and second ejector devices to work together to eject products from their corresponding areas on the chain conveyor line. Meanwhile, when the chain conveyor line is relatively stationary by the first drive component and the second drive component, the chain on the chain conveyor line will be slightly slack. At this time, the area of ​​the chain conveyor line where the product can be ejected by the first ejection device and the second ejection device will also be offset, so that the product cannot be ejected. However, by setting the first buffer drive component and the second buffer drive component to move the chain conveyor line, the chain can be tightened, so that the area of ​​the chain conveyor line where the product needs to be ejected corresponds to the first ejection device and the second ejection device, so that the product can be smoothly ejected by the first ejection device and the second ejection device.

[0012] In one embodiment, the frame has, in sequence, an inlet area, a first buffer zone, a first ejection area, a second buffer zone, and a second ejection area along its circumferential direction;

[0013] Along the conveying direction of the chain conveyor line, the chain conveyor line is located at the inlet area, the first buffer zone, the first ejection zone, the second buffer zone, and the second ejection zone, which are respectively the inlet, the first buffer section, the first ejection section, the second buffer section, and the second ejection section;

[0042] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0043] One embodiment of this utility model relates to a dual-outlet feather stacker 100 with buffer. For example... Figure 1 and Figure 2As shown, the dual-outlet stacker crane 100 with buffered feathers includes: a frame 1, a chain conveyor line 2, a first drive assembly 5, a second drive assembly 6, a first ejection device 7, a second ejection device 8, a first buffer drive assembly 3, and a second buffer drive assembly 4. The chain conveyor line 2 is looped around the frame 1 and has multiple feathers 20, with adjacent feathers 20 used to clamp products 200. The first drive assembly 5 and the second drive assembly 6 are both mounted on the frame 1 and are used to drive the chain conveyor line 2 to convey products 200. Multiple feathers 20 are arranged along the direction of the chain conveyor line 2, with adjacent feathers 20 clamping products 200. When the chain conveyor line 2 conveys products 200, the first drive assembly 5 and the second drive assembly 6 are also used to provide power to the chain conveyor line 2 in opposite directions, keeping the chain conveyor line 2 relatively stationary. The first ejection device 7 and the second ejection device 8 are located on different sides of the frame 1 and are used to eject products 200 from different areas of the chain conveyor line 2. A first buffer drive assembly 3, mounted on the frame 1, drives the area adjacent to the first ejector 7 of the chain conveyor 2 to move relative to the first ejector 7, and also tensions the chain of the chain conveyor 2. A second buffer drive assembly 4, mounted on the frame 1, drives the area adjacent to the second ejector 8 of the chain conveyor 2 to move relative to the second ejector 8, and also tensions the chain of the chain conveyor 2. This product 200 can be, for example, diapers or sanitary pads. The first ejector 7 corresponds to one outlet on the chain conveyor 2, and the second ejector 8 corresponds to the other outlet on the chain conveyor 2.

[0044] Specifically, the first drive assembly 5 includes a motor and a transmission component, which may include gears, etc. The motor drives the transmission component, which in turn drives the chain of the chain conveyor line 2, thereby moving the conveyor belt connected to the chain. The structure of the second drive assembly 6 is similar to that of the first drive assembly 5, and will not be described in detail here. In this example, the chain conveyor line 2 is kept almost stationary by making the motors of the first drive assembly 5 and the second drive assembly 6 rotate in opposite directions. Specifically, the motor of the first drive assembly 5 can rotate in reverse while the motor of the second drive assembly 6 rotates forward simultaneously; or the motor of the first drive assembly 5 can rotate forward while the motor of the second drive assembly 6 rotates in reverse simultaneously.

[0045] The stacker crane has two product outlets: a first ejector device 7 and a second ejector device 8, which are arranged around the frame 1. The first ejector device 7 and the second ejector device 8 can respectively eject the corresponding product 200 from the chain conveyor 2 and send it into a packaging bag. This means the stacker crane has two product outlets 200, thereby improving production efficiency. Additionally, a first drive assembly 5 and a second drive assembly 6 drive the chain conveyor 2. When the chain conveyor 2 transports the product 200 to a suitable position where it can be ejected by the first ejector device 7 and the second ejector device 8, the first drive assembly 5 and the second drive assembly 6 are controlled to simultaneously apply opposing driving forces to the chain conveyor 2, thus keeping the chain conveyor 2 relatively stationary. This allows the first ejector device 7 and the second device to eject the product 200 from the corresponding area of ​​the chain conveyor 2. Meanwhile, when the chain conveyor 2 is relatively stationary by the first drive component 5 and the second drive component 6, the chain on the chain conveyor 2 will be slightly slack. At this time, the area of ​​the chain conveyor 2 that the first ejection device 7 and the second ejection device 8 correspond to that of the product 200 will also be offset, so that the product 200 cannot be ejected. However, by setting the first buffer drive component 3 and the second buffer drive component 4 to move the chain conveyor 2, the chain can be tightened, so that the area of ​​the chain conveyor 2 that the product 200 needs to be ejected corresponds to the first ejection device 7 and the second ejection device 8, so that the product 200 can be smoothly ejected by the first ejection device 7 and the second ejection device 8.

[0046] Furthermore, along the circumferential direction of frame 1, there are sequentially an inlet area, a first buffer zone, a first ejection area, a second buffer zone, and a second ejection area. For example... Figure 1 , Figure 2 As shown, along the conveying direction of the chain conveyor line 2, the inlet area, first buffer zone, first ejection zone, second buffer zone, and second ejection zone are sequentially located as inlet 21, first buffer section 22, first ejection section 23, second buffer section 24, and second ejection section 25. That is, the portion of the chain conveyor line 2 that drives to the inlet area is inlet 21, the portion in the first buffer zone is first buffer section 22, the portion in the first ejection zone is first ejection section 23, the portion in the second buffer zone is second buffer section 24, and the portion in the second ejection zone is second ejection section 25. First buffer section 22 is adjacent to first ejection section 23, and first ejection device 7 is used to eject the product 200 on first ejection section 23. Second buffer section 24 is adjacent to second ejection section 25, and second ejection device 8 is used to eject the product 200 on second ejection section 25. First ejection device 7 and second ejection device 8 have roughly the same structure, and the areas corresponding to first ejection device 7 and second ejection device 8 are both outlets of the chain conveyor line 2. Taking first ejection device 7 as an example... Figure 5The first ejection device 7 includes: a support frame 71 fixed on the frame 1; a push motor 72 mounted on the support frame 71; a conveyor belt 73 driven by the push motor 72; a guide rail 74 extending along the extension direction of the conveyor belt 73; a fixing block 75 fixed on the conveyor belt 73; and a push arm 76 movably connected to the fixing block 75. The fixing block 75 is slidably connected to the guide rail 74. The conveyor belt 73 carries the fixing block 75 along the guide rail 74, and the fixing block 75 carries the push arm 76. The push arm 76 has multiple push teeth, one of which is inserted between two feathers 20 to push the product 200 away from the feathers 20. The first ejection device 7 also includes a rotary motor 77 that drives the push arm 76 to rotate, thereby allowing the push arm to be raised or lowered.

[0047] In addition, such as Figure 1 , Figure 2 As shown, the first buffer drive assembly 3 and the second buffer drive assembly 4 are disposed on different sides of the rack 1.

[0048] In addition, such as Figure 1 , Figure 2 As shown, the frame 1 has a first mounting side 11, a second mounting side 12, a third mounting side 13, and a fourth mounting side 14 connected in sequence, wherein the first mounting side 11 and the third mounting side 13 are arranged opposite to each other, and the second mounting side 12 and the fourth mounting side 14 are arranged opposite to each other. The chain conveyor line 2 has a first conveying section located on the first mounting side 11, a second conveying section located on the second mounting side 12, a third conveying section located on the third mounting side 13, and a fourth conveying section located on the fourth mounting side 14. A first ejection device 7 is disposed on the first mounting side 11, and a second ejection device 8 is disposed on the second mounting 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 extension direction of the first conveying section. The first buffer motor 31 drives the first pulley group 32 to transmit power along the extension 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 is in motion, 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, thereby driving the chain 27 of the stretch chain conveyor line 2. Specifically, the rotation of the main shaft of the first buffer motor 31 drives the drive wheel 322 of the first pulley group 32 to rotate. The drive wheel 322 drives the conveyor belt 321 of the first pulley group 32. The conveyor belt 321 carries the first sprocket group 34 to move along the first track 33. Thus, the first sprocket group 34 carries 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, allowing the product 200 on the chain conveyor line 2 to move to the first ejection device 7 and be accurately ejected.

[0049] Furthermore, such as Figure 1 , Figure 3 As shown, the first sprocket assembly 34 includes: a first main sprocket 341 and a first mounting base 342 connected to 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 assembly 32, so that the conveyor belt drive can drive the first mounting base 342, which in turn drives the first sprocket assembly 34. The first buffer drive assembly 3 also 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, such as Figure 1 , Figure 3 As shown, 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 being operable to roll along the first auxiliary track 36. The first roller 37 is disposed on the second conveying section, and 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] Furthermore, such as Figure 1 , Figure 3 As shown, the first auxiliary track 36 extends toward the fourth conveyor section and bends toward the third conveyor section.

[0052] In addition, such as Figure 1 , Figure 4 As shown, the second buffer drive assembly 4 includes: a second buffer motor 41, a second pulley assembly 42, a second track 43, and a second sprocket assembly 44. The second track 43 extends along the extension direction of the fourth conveying section, and the second buffer motor 41 drives the second pulley assembly 42 to move along the extension direction of the fourth conveying section. The second sprocket assembly 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 assembly 44 is slidably mounted on the second track 43. When the second pulley assembly 42 is in operation, it drives the second sprocket assembly 44 to slide along the second track 43. When the second sprocket assembly 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, such as Figure 1 , Figure 4As shown, the second sprocket assembly 44 includes a second main sprocket 441 and a second mounting base 442 connected to the second main sprocket 441. The second mounting base 442 is slidably connected to the second track 43. The second buffer drive assembly 4 also includes a second auxiliary sprocket 45, which is mounted on the frame 1. The second auxiliary sprocket 45 is spaced apart from the second main sprocket 441 along the extension direction of the third conveying section. The second main sprocket 441 is located at the corner between the third and fourth conveying sections. 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.

[0054] Furthermore, such as Figure 1 , Figure 4 As shown, the second buffer drive 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. The second roller 47 is located in the third conveying section, and 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 towards the third mounting side 13 and bends towards the second conveying section. 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.
