Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, and in particular to a rapid counting, grouping and bag discharging device. Background Art

[0002] During the production process of some bags, it is necessary to count, group and stack the produced bags for subsequent packaging and transportation.

[0003] However, in the prior art, for example, a bag counting and receiving device disclosed in CN211336704U can only count bags, but cannot automatically group them, thus failing to meet the production requirements.

[0004] Moreover, when some bags are conveyed on a conveyor belt, a part of adjacent bags overlaps, making it more difficult to group them. That is, it is difficult to accurately and quickly group and separate the bags using conventional devices.

[0005] In addition, conventional rapid counting, grouping and bag discharging devices for bags are usually only applicable to the same type of bags and are difficult to produce bags of different sizes. That is, when the paper bag specifications vary greatly, it is very difficult to adjust the number of discharged bags, and the applicability is poor.

[0006] The present invention is made based on this situation. Summary of the Invention

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0029] Such as Figures 1 to 5A rapid counting and grouping bag discharging device as shown in the figure includes a frame 1. On the frame 1, a first conveying mechanism 2, a second conveying mechanism 3, and a bag receiving mechanism 4 capable of receiving the bags output by the second conveying mechanism 3 are sequentially arranged along the conveying direction. The rapid counting and grouping bag discharging device of the present invention can be applied to the counting, grouping, and grouped stacking of various bags, and can also be used for bags in stacked transmission (with overlapping edges between adjacent bags during transmission), such as Figure 1 as shown in the figure.

[0030] Among them, the first conveying mechanism 2 includes a first conveyor belt 21 and a first driving device 22 for driving the first conveyor belt 21 to run at a constant speed. Usually, the first conveyor belt 21 runs at a constant speed. Of course, the first driving device 22 is preferably an ordinary driving motor.

[0031] The second conveying mechanism 3 includes a second conveyor belt 31 and a second driving device 32 for driving the second conveyor belt 31 to run at a variable speed. The second driving device 32 is preferably a frequency conversion motor. The second conveyor belt 31 has two working states. One is to run at a constant speed the same as that of the first conveyor belt 21, and the other is to quickly increase the speed. That is, whenever the counting sensor 51 detects that a predetermined number of bags have passed, the second driving device 32 will accelerate to quickly convey the bags on it forward. When the second conveying mechanism 3 accelerates to work, the conveying line speed can be increased by 8 times based on the original speed.

[0032] Such as Figure 1 , Figure 4 as shown in the figure, a counting and bag separating mechanism 5 is further provided on the frame 1. The counting and bag separating mechanism 5 includes a counting sensor 51 arranged above the first conveyor belt 21 and a tail bag pushing device 52 arranged below the first conveyor belt 21 and capable of quickly pushing the bags on the first conveyor belt 21 forward onto the second conveyor belt 31 at a speed faster than that of the first conveyor belt 21. The counting sensor 51 is usually an optical sensor, such as a laser counting sensor, mainly used for counting the number of passing bags. In the present invention, whenever the counting sensor 51 detects that a predetermined number of bags have passed, the tail bag pushing device 52 will be activated to quickly send the counted bags forward onto the second conveyor belt 31, and the uncounted bags will still move slowly on the first conveyor belt 21, so that the uncounted bags and the counted bags can be separated.

[0033] More specifically, such as Figure 4 , Figure 5As shown, the tail bag pushing device 52 includes a pushing block 521 that can extend upward the first conveyor belt 21 to lift the bag body and can quickly push the bag body forward onto the second conveyor belt 31 at a speed faster than that of the first conveyor belt 21, and a pushing driving device 522 for driving the pushing block 521 to operate. Of course, at least one pushing block 521 is just located below the tail bag when starting. Here, the tail bag refers to the last bag body that has been counted in each group. It should be noted that this way of lifting the bag body is not affected by the size and specification of the bag body. As long as the counting sensor 51 detects that the bag body meets the predetermined quantity, the pushing block 521 will push the counted bag bodies forward all at once, and this process has nothing to do with the size and specification of the bag body. Therefore, the applicability of the present invention is high, and when conveying bag bodies of different sizes and specifications, no major adjustment is required.

[0034] Furthermore, as Figure 4 , Figure 5 shown, the pushing driving device 522 includes at least two driving wheels 5221 provided on the frame 1, a transmission belt 5222 provided between the driving wheels 5221, and a pushing driver 5223 for driving the driving wheels 5221 to rotate. One section of the transmission belt 5222 is arranged along the conveying direction; the pushing block 521 is fixed on the transmission belt 5222. Preferably, the driving wheels 5221 are sprockets, the transmission belt 5222 is a chain, and the pushing driver 5223 is preferably a servo motor or a stepping motor. The pushing driver 5223 usually stops running. When the counting sensor 51 detects that a predetermined number of bag bodies pass by, the pushing driver 5223 immediately starts and runs for a short period of time, and this speed is much faster than the speed of the first conveyor belt 21. After the pushing driver 5223 starts, the pushing block 521 will extend from below the first conveyor belt 21 and travel a certain distance along the conveying direction, so as to quickly push all the counted packages onto the second conveyor belt 31.

[0035] More specifically, an origin sensor 53 for detecting the position of the pushing block 521 is provided on the frame 1. The running time of the pushing driver 5223 is the same each time it starts. The origin sensor 53 is used to correct the staying position of the pushing block 521. Usually, when the pushing driving device 522 is stationary, at least one pushing block 521 stays at the origin sensor 53. When the pushing driving device 522 starts for a period of time and the origin sensor 53 detects the pushing block 521 again, the pushing driver 5223 just stops.

[0036] More specifically, at least two of the above-mentioned pushing blocks 521 are provided on the transmission belt 5222, and the pushing blocks 521 are evenly spaced on the transmission belt 5222. As Figure 4 , Figure 5In the shown figure, there are two evenly distributed pushing blocks 521. When one of the pushing blocks 521 reaches the origin sensor 53, the other pushing block 521 is just at the rear end of the conveyor belt 5222 and exactly below the first conveyor belt 21. And once the conveyor belt 5222 starts, this pushing block 521 immediately extends upward out of the first conveyor belt 21.

[0037] The working principle of the present invention includes the following steps:

[0038] 1) The bag bodies are continuously input into the first conveyor belt 21 in sequence and are conveyed forward at a uniform speed on the first conveyor belt 21. At the same time, the second conveyor belt 31 also keeps running at a uniform speed, and its speed is the same as that of the first conveyor belt 21.

[0039] 2) When the bag body enters the recognition range of the counting sensor 51, the counting sensor 51 starts this counting.

[0040] 3) When the counted number of bag bodies reaches the preset value, the pushing drive 5223 is quickly started. Driven by the conveyor belt 5222, the pushing block 521 starts to lift the bag body, holds up the tail bag and a part of the bag bodies in front of the tail bag that have been counted, and quickly pushes these bag bodies forward, and this speed is much greater than the speed of the first conveyor belt 21. After pushing for a short time, the pushing block 521 reaches the position of the origin sensor 53, and the pushing drive 5223 immediately stops. Due to the boost of the pushing block 521 and the inertia of the bag body itself, the bag body will be pushed onto the second conveyor belt 31. And these bag bodies have all been counted, and the bag bodies that have not been counted are still slowly running at a uniform speed on the first conveyor belt 21. Therefore, a large gap will be generated between the counted and uncounted bag bodies, and the two are actually separated.

[0041] 4) At the same time when the counted number of bag bodies reaches the preset value and the pushing drive 5223 is started, the second conveyor belt 31 will also immediately increase its speed, increasing to about 8 times the original linear speed, and quickly conveys the bag bodies on it forward to the bag receiving mechanism 4. When the above-mentioned pushing block 521 reaches the position of the origin sensor 53, the second conveyor belt 31 first continues to run at a high speed for a short period of time, and then resumes running at a low speed and at a uniform speed.

[0042] 5) The bag bodies output from the second conveyor belt 31 will fall into the third conveyor belt 41 (detailed later) in sequence, and are quickly stacked and aligned, and finally grouped and discharged.

[0043] The present invention can quickly and accurately count and group the bag bodies, and finally stack and discharge them in groups. This process is fully automated, without manual intervention, and is fast and efficient.

[0044] In addition, the pushing driving device of the present invention uses the method of pushing up the bag body by the pushing block 521 and then accelerating it forward onto the second conveyor belt 31, and the second conveyor belt 31 then conveys it forward at a high speed together, so as to realize the rapid counting and grouping of the bag body. Moreover, since the method of pushing up the bag body in this way is not affected by the size and specification of the bag body, it has a high adaptability to bag bodies of different specifications.

[0045] More specifically, a first spacing adjustment structure 5224 is provided between the two driving wheels 5221. The first spacing adjustment structure 5224 can conveniently adjust the spacing between the two driving wheels 5221 for assembly. For example, Figure 5 As shown, a preferred structure of the first spacing adjustment structure 5224 is as follows: The first spacing adjustment structure 5224 includes a mounting frame. Strip-shaped holes are provided on the left and right sides of the mounting frame. Mounting rods are respectively provided in the strip-shaped holes. Mounting plates perpendicular to the mounting rods are provided on the mounting rods, and the two driving wheels 5221 are respectively arranged on the two mounting plates. Therefore, the spacing between the two driving wheels 5221 can be adjusted by adjusting the spacing between the two mounting rods.

[0046] More specifically, as Figure 1 shown, a guiding and flattening device 33 is provided at the output port of the second conveyor belt 31. The guiding and flattening device 33 mainly plays the roles of guiding and flattening, that is, one is to prevent the bag body from flying away directly, and the other is to flatten the bag body, which is beneficial for subsequent stacking.

[0047] Further, the guiding and flattening device 33 includes a large wheel 331 that is movably connected to the frame 1 and can float up and down, and the large wheel 331 presses on the second conveyor belt 31 due to gravity. Further, the guiding and flattening device 33 further includes a swing rod 332. The middle of the swing rod 332 is rotatably connected to the frame 1. The large wheel 331 is rotatably connected to one end of the swing rod 332. A small wheel 333 is rotatably connected to the other end of the swing rod 332. A belt 334 connecting the two is provided between the large wheel 331 and the small wheel 333. The large wheel 331 is relatively heavy, and the small wheel 333 is relatively light. Neither the large wheel 331 nor the small wheel 333 has an active driving force and is rotated passively.

[0048] More specifically, as Figures 2 - 3 shown, the frame 1 includes a left support 11 and a right support 12. First conveying mechanisms 2 and second conveying mechanisms 3 are provided on both the left support 11 and the right support 12. A second spacing adjustment structure 13 is provided between the left support 11 and the right support 12. The second spacing adjustment structure 13 is mainly used to adjust the spacing between the left support 11 and the right support 12, so as to adjust the spacing between the two first conveying mechanisms 2 on the left and right, and the spacing between the two second conveying mechanisms 3 on the left and right, so as to adapt to the transmission of bag bodies of different widths, making the applicability wider.

[0049] As Figure 3As shown, a preferred specific structure of the second pitch adjustment structure 13 is as follows: The second pitch adjustment structure 13 includes a cross-type telescopic frame 131 connected between the left bracket 11 and the right bracket 12, and a lead screw pair 132 for adjusting the pitch between the left bracket 11 and the right bracket 12. Of course, the two first conveying mechanisms 2 on the left bracket 11 and the right bracket 12 can share the same driver (the first driving device 22), but a telescopic transmission shaft needs to be used for transmission. Similarly, a telescopic transmission shaft can also be used for transmission between the two second conveying mechanisms 3 on the left bracket 11 and the right bracket 12.

[0050] More specifically, as Figures 1 - 3 shown, the bag collection mechanism 4 includes a third conveyor belt 41, a third driving device 42 for driving the third conveyor belt 41, and an automatic gate device 43 provided above the third conveyor belt 41. The automatic gate device 43 includes an intercepting gate 431 and an intercepting driving device 432 for driving the intercepting gate 431 to flip up and down for opening and closing. The third driving device 42 is preferably a motor. The intercepting driving device 432 is preferably a cylinder.

[0051] As Figure 1 shown, the front part of the third conveyor belt 41 is lower than the second conveyor belt 31. The bags ejected from the second conveyor belt 31 fall onto the third conveyor belt 41 in sequence and are continuously stacked layer by layer. The third conveyor belt 41 keeps moving forward slowly. When the bags touch the intercepting gate 431, they stop moving forward and wait for the stacking of the bags to be completed. At the same time, the bags will be aligned due to the interception of the intercepting gate 431. When the stacking of the set number of bags in this group is completed, the intercepting gate 431 opens, and this group of bags passes through and is conveyed forward to the receiving area.

[0052] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
