[0002] In automated control systems, especially in the logistics sorting and packaging industries, packages often need to be transported and sorted. Among them, the pendulum device is a commonly used device that drives the package forward by rotating to achieve the purpose of transportation. In practical applications, since the size, shape and weight of packages may vary, the distance between two packages may be too close during transportation, which brings inconvenience to subsequent sorting.

The conveying channel conveys products (e.g., Figure 7 The product A and product B shown in the figure are, for example, express boxes, etc. The conveying channel includes an input channel 100 and an output channel 101. A balance wheel device 200 described later is provided between the input channel 100 and the output channel 101. That is, the balance wheel device 200 connects the input channel 100 and the output channel 101, and moves along a first direction (i.e. Figure 1 The sorting channels are located on both sides of the balance wheel device 200. For ease of understanding, the sorting channel located on the left side of the balance wheel device 200 is named the first sorting channel 103, and the sorting channel located on the right side of the balance wheel device 200 is named the second sorting channel 104. The direction change driving unit 203 of the balance wheel device 200 is used to drive at least one bearing unit 202 of the balance wheel device 200 to rotate around the third direction (i.e. Figure 2 Z direction) to rotate the product relative to the second direction (i.e. Figure 1 The sorting channel 104 is deflected (in the Y direction shown) to the first sorting channel 103 or the second sorting channel 104.

[0053] For example, the product is fed through the input channel 100 along the Figure 1 The product is transported to the balance wheel device 200 in the direction a shown in the figure. The specific transport path of the product is determined according to the encoder on the product. If it is shown that the product should be transported to the output channel 101, the balance wheel device 200 moves along the Figure 1 The product is transported to the output channel 101 in the direction shown in a. If the product is shown to be transported to the first sorting channel 103, the balance wheel device 200 moves along Figure 1 The product is transported from the first chute (not shown) to the first sorting channel 103 in the direction b shown in the figure. If the product is shown to be transported to the second sorting channel 104, the balance wheel device 200 moves along Figure 1 The product is transported from the second chute (not shown) to the second sorting channel 104 in the direction c shown.

[0054] Combine the following Figures 2 to 7 , the structure of the balance wheel device 200 is introduced in detail.

[0055] Exemplarily, the balance wheel device 200 includes: a panel 201, a plurality of bearing parts 202 corresponding to a plurality of balance wheels 205, a direction change driving part 203 and a plurality of speed change driving parts 204. The panel 201 is provided with a plurality of balance wheels 205, and the plurality of balance wheels 205 are used to rotate in a first direction (i.e. Figure 2 X direction) to transport the product along the second direction (i.e. Figure 2Each balance wheel 205 and its corresponding bearing portion 202 move forward in a first direction (i.e. Figure 2 The direction change driving unit 203 includes an output shaft, which is rotatable in the third direction (ie Figure 2 The output shaft is connected to at least one bearing portion 202 and is used to drive at least one bearing portion 202 to rotate in a third direction (ie, Figure 2 Z direction) to rotate the product relative to the second direction (i.e. Figure 2 Each speed change driving unit 204 is electrically connected to at least two balance wheels 205 for changing the operating speed of at least two balance wheels 205 at the same time.

[0056] Specifically, combined Figure 6 , product A is conveyed to the balance wheel 205, and as the balance wheel 205 rotates in the first direction (i.e. Figure 6 The X direction shown in the figure) rotates, and when rotating, provides a second direction (i.e. Figure 6 The driving force of the direction change driving unit 203 (in the Y direction shown in the figure) is used to convey the products on the balance wheel 205 forward along the second direction to complete the conveying function. At the same time, a direction change driving unit 203 is provided. The output shaft of the direction change driving unit 203 is connected to at least one bearing unit 202. The bearing unit 202 is connected to the balance wheel 205 in a rotatable manner along the first direction. When the products on the balance wheel 205 need to be sorted, the direction change driving unit 203 drives the bearing unit 202 to rotate around the third direction to drive the balance wheel 205 to rotate around the third direction, so that the products on the balance wheel 205 are subjected to a force of deflection in the second direction relative to the forward movement, for example, the balance wheel 205 rotates to the left around the third direction, so that the product A on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, so that the product A is moved forward along the balance wheel 205. Figure 6 The movement in direction b shown is the conversion of the movement trajectory of product A into the movement trajectory of product A', thereby driving the product on the balance wheel 205 to deflect in the second direction to achieve sorting.

[0057] A speed change driving unit 204 is provided, and the speed change driving unit 204 is electrically connected to at least two balance wheels 205. When the distance between two products is too close, the speed change driving unit 204 can be started to change the movement speed of at least two balance wheels 205, thereby changing the running speed of the products on at least two balance wheels 205, so as to increase the distance between the products and the products close to them, thereby preventing the problem of sorting failure caused by the close distance between the two products.

[0058] The first direction (i.e. Figure 2 The X direction shown), the second direction (i.e. Figure 2 The Y direction shown) and the third direction (i.e. Figure 2In the Z direction shown in the figure, they intersect respectively. For the convenience of demonstration, the embodiment of the present application is explained by taking the first direction, the second direction and the third direction being perpendicular to each other as an example.

[0059] Exemplarily, the direction change driving unit 203 is a servo motor, but is not limited thereto, and may also be a linear motor, a stepping motor, etc., and the speed change driving unit 204 is a balance wheel driving card.

[0060] It should be noted that the embodiment of the present application does not limit the number of the balance wheels 205, the number of the bearing parts 202, the number of the direction change driving parts 203, and the number of the speed change driving parts 204. The number of the balance wheels 205 can be 30, 40, 45, 50, 59, etc., and the number of the bearing parts 202 is the same as the number of the balance wheels 205. The number of the direction change driving parts 203 can be the same as the number of the balance wheels 205, that is, one direction change driving part 203 drives one bearing part 202 to rotate, or it can be less than the number of the balance wheels 205, that is, one direction change driving part 203 drives multiple bearing parts 202 to rotate. The number of the speed change driving parts 204 is less than the number of the balance wheels 205, that is, one speed change driving part 204 changes the movement speed of multiple balance wheels 205.

[0061] Exemplarily, the balance wheel device 200 also includes a bottom plate 206 and four side plates 207. The bottom plate 206, the four side plates 207 and the panel 201 together form a quadrilateral placement space 208. Multiple bearing parts 202, direction change drive parts 203 and multiple speed change drive parts 204 are located in the placement space 208 to prevent the external environment from affecting the various components, such as dust ingress, and affecting their working conditions.

[0062] It should be noted that the embodiment of the present application does not limit the number of side panels 207, that is, there is no restriction on the shape of the placement space 208. The number of side panels 207 can also be five, which together with the bottom plate 206 form a pentagonal placement space 208, as long as it can accommodate multiple bearing parts 202, direction change drive parts 203 and multiple speed change drive parts 204.

[0063] Exemplarily, the balance wheel device 200 further includes four legs 209 , which are connected to a side of the bottom plate 206 facing away from the panel 201 . The legs 209 can be used to contact the ground or a workbench to ensure the stability of the entire balance wheel device 200 .

[0064] Exemplarily, the panel 201 is provided with a plurality of circular through holes 210 corresponding one by one to the plurality of balance wheels 205, and a fixing member 211 is provided in the through hole 210. The fixing member 211 is located on both sides of the balance wheel 205, and the fixing member 211 abuts against the balance wheel 205 so that a part of the balance wheel 205 is located in the through hole 210, so as to ensure the normal operation of the balance wheel 205 on the panel 201.

[0065] Exemplarily, the bearing portion 202 includes a bearing bottom plate 212 and four bearing side plates 213, which together form a quadrilateral bearing space, and the bearing space is connected to the above-mentioned through hole 210. Another part of the balance wheel 205 is placed in the bearing space, and the balance wheel 205 is rotatably connected to two of the bearing side plates 213 of the bearing space, so that the balance wheel 205 can rotate around a first direction to transport the product on the balance wheel 205 forward along a second direction to complete the conveying function.

[0066] It should be noted that the embodiment of the present application does not limit the number of the load-bearing side plates 213, that is, there is no restriction on the shape of the load-bearing space. The number of the load-bearing side plates 213 can also be five, which together with the load-bearing bottom plate 212 form a pentagonal load-bearing space as long as the balance wheel 205 can be placed.

[0067] Exemplarily, the balance wheel device 200 also includes a first connecting member 214 and a second connecting member 215, one end of the first connecting member 214 is connected to the supporting base plate 212 of at least two supporting parts 202, and the other end is connected to one end of the second connecting member 215, and the other end of the second connecting member 215 is connected to the output shaft of the direction change driving part 203, so that the direction change driving part 203 can simultaneously control the at least two supporting parts 202.

[0068] When a row of the load-bearing parts 202 needs to be controlled, the entire row of the load-bearing parts 202 can be connected together through a cross bar, and then connected to the first connecting member 214 and the second connecting member 215 .

[0069] Exemplarily, the balance wheel device 200 further includes a heat dissipation unit 216, which is disposed on one of the four side panels 207. The heat dissipation unit 216 is, for example, a fan, which dissipates heat from the direction change drive unit 203 and the speed change drive unit 204 to prevent overheating and affecting their performance and service life. Each side panel 207 is provided with a plurality of heat dissipation holes 217, through which the heat inside the placement space 208 can be dissipated to the outside, preventing the excessive heat inside the placement space 208 from affecting the performance and service life of its internal parts (such as the direction change drive unit 203 and the speed change drive unit 204).

[0070] Exemplarily, the plurality of balance wheels 205 are arranged in ten rows, and the plurality of balance wheels 205 are arranged in rows to form three conveying zones, wherein the balance wheels 205 are arranged in a row to form three conveying zones, wherein the balance wheels 205 are arranged in a row to form three conveying zones, and ... Figure 2 The first three rows are the first conveying area 218, the next three rows are the second conveying area 219, and the last four rows are the third conveying area 220. That is, the first conveying area 218 includes three rows of balance wheels 205, the second conveying area 219 includes three rows of balance wheels 205, and the third conveying area 220 includes four rows of balance wheels 205, and the first conveying area 218, the second conveying area 219 and the third conveying area 220 are respectively along the second direction (i.e. Figure 2 At least two balance wheels 205 in the same conveying area are electrically connected to the same speed change driving unit 204, and at least one bearing unit 202 in the same conveying area is connected to the output shaft of the same direction change driving unit 203.

[0071] By adopting the above technical solution, the balance wheels 205 are arranged in a row to form multiple conveying areas. The speed and direction of the balance wheels 205 in each conveying area can be changed at the same time, so that the speed and direction of products located in the same conveying area can be kept consistent, which is convenient for sorting and spacing control.

[0072] It should be noted that the embodiment of the present application does not limit the number of rows of balance wheels 205, the number of conveying zones, and the number of rows of balance wheels 205 included in each conveying zone. It can also be nine rows of balance wheels 205, twelve rows of balance wheels 205, etc., and each conveying zone includes three rows of balance wheels 205 or four rows of balance wheels 205, etc.

[0073] The embodiment of the present invention also discloses a control method, referring to Figure 7 and Figure 8 Combined with Figure 1 and Figure 2 First, a plurality of products are provided. The plurality of products are placed on the conveyor belt of the input channel 100 manually or by machine, and move along the input channel 100 at a first speed in sequence under the action of the conveyor belt; for example, the first speed is 2 m / s, but it is not limited thereto, and may also be 1.5 m / s, 2.1 m / s, 2.15 m / s, etc. A photoelectric sensor 300 is provided on the input channel 100, and the plurality of products pass through the photoelectric sensor 300 in sequence, and the signal is transmitted to the PLC (Programmable Logic Controller). The PLC calculates the distance between two adjacent products according to the speed of the conveyor belt. For example, at this time, two adjacent products (i.e. Figure 7 The distance between product A and product B shown (i.e. Figure 7 The L1) shown is 400mm and the first distance is 450mm.

[0074] And determine the two adjacent products (i.e. Figure 7 The target channels of product A and product B) shown in the figure, for example, product A needs to be conveyed to the first sorting channel 103, and product B needs to be conveyed to the second sorting channel 104. As mentioned above, the sorting channels are located on both sides of the balance wheel device 200, the first sorting channel 103 is located on the left side of the balance wheel device 200, and the second sorting channel 104 is located on the right side of the balance wheel device 200.

[0075] Determine two adjacent products among multiple products (i.e. Figure 7 The spacing between product A and product B) shown is smaller than the first distance, that is, 400mm is smaller than 450mm, that is, the spacing between product A and product B is smaller, but the size of the first distance is not limited to this, and can be set according to actual needs, for example, it can also be 500mm, 550mm, 570mm, etc.

[0076] If the distance between the two products is not increased, if the two products need to be sorted to different sorting channels, sorting failure will occur.

[0077] At this time, combined with Figure 3 , the PLC sends a sawing instruction to the speed change driving unit 204. Specifically, in the first time, for example, the first time is 5s, but not limited to this, it can also be 4s, 6s, 6.5s, etc. The speed change driving unit 204 increases the speed of all the balance wheels 205 in the first conveying area 218 to the second speed, for example, the second speed is 2.5m / s, but not limited to this, it can also be 2.15m / s, 2.6m / s, 3.15m / s, etc. The second speed is greater than the first speed, and the first conveying area 218 includes the above-mentioned three rows of balance wheels 205.

[0078] At the same time, the PLC issues a command to the direction change driving unit 203, and the direction change driving unit 203 drives the carrying portion 202 of the first conveying area 218 to rotate around the third direction, so as to drive the balance wheel 205 to rotate around the third direction, so that the product A on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, for example, the balance wheel 205 rotates to the left around the third direction, so that the product A on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, so that the product A is moved along the Figure 6 The movement in direction b shown is the conversion of the movement trajectory of product A into the movement trajectory of product A′, thereby driving product A on the balance wheel 205 to deflect and move in the second direction.

[0079] The first time is the product located in front of the two adjacent products (i.e. Figure 7 The time when the product A) is conveyed to the first conveying area 218, the distance between the photoelectric sensor 300 and the first conveying area 218 (i.e. Figure 7L2 shown in FIG. 1 is determined, the conveying speed of the conveyor belt of the input channel 100 is determined, and the product located in front of the two adjacent products (i.e. Figure 7 The time required for the product A) to be conveyed to the first conveying area 218 after passing through the photoelectric sensor 300 is referred to as the first time.

[0080] The second speed is such that product B is conveyed to the first conveying area 218 at the same time or after product A leaves the first conveying area 218 .

[0081] Then, when product A leaves the first conveying area 218, product B is conveyed to the first conveying area 218. The PLC receives the signal and sends an instruction to the speed change drive unit 204 to drive the balance wheel 205 in the first conveying area 218 to return to the first speed and convey product B at the first speed.

[0082] At the same time, the PLC issues a command to the direction change driving unit 203, and the direction change driving unit 203 drives the carrying unit 202 of the first conveying area 218 to rotate around the third direction, so as to drive the balance wheel 205 to rotate around the third direction, so that the product B on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, for example, the balance wheel 205 rotates rightward around the third direction, so that the product B on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, so that the product B is moved along the Figure 1 The movement in the c direction shown drives the product B on the balance wheel 205 to deflect and move relative to the second direction.

[0083] In the second time, for example, the second time is 7s, but not limited thereto, and may also be 6.5s, 7.15s, 7.5s, etc. The speed change driving unit 204 increases the speed of all the balance wheels 205 in the second conveying area 219 to the second speed, the second time is greater than the first time, the second conveying area 219 includes the above-mentioned three rows of balance wheels 205, the first conveying area 218 and the second conveying area 219 are spaced apart along the second direction, and the first conveying area 218 is closer to the product.

[0084] At the same time, the PLC issues a command to the direction change driving unit 203, and the direction change driving unit 203 drives the carrying unit 202 of the second conveying area 219 to rotate around the third direction, so as to drive the balance wheel 205 to rotate around the third direction, so that the product A on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, for example, the balance wheel 205 rotates to the left around the third direction, so that the product A on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, so that the product A is moved along the Figure 6 The movement in direction b shown is the conversion of the movement trajectory of product A into the movement trajectory of product A′, thereby driving product A on the balance wheel 205 to continue to deflect and move relative to the second direction.

[0085] The first speed is determined, and the length of the first conveying area 218 (i.e. Figure 7 L3) shown in the figure has been determined, from which it can be concluded that the product located in front of the two adjacent products (i.e. Figure 7 How long does it take for the product A) shown in the figure to travel from the first conveying area 218 to the second conveying area 219? Assuming that this time is the interval time, for example, the interval time is 2s, then the second time 7s is equal to the first time 5s plus the interval time 2s.

[0086] Then, when product A leaves the second conveying area 219, product B is conveyed to the second conveying area 219. The PLC receives the signal and sends an instruction to the speed change drive unit 204 to drive the balance wheel 205 in the second conveying area 219 to return to the first speed and convey product B at the first speed.

[0087] At the same time, the PLC issues a command to the direction change driving unit 203, and the direction change driving unit 203 drives the carrying unit 202 of the second conveying area 219 to rotate around the third direction, so as to drive the balance wheel 205 to rotate around the third direction, so that the product B on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, for example, the balance wheel 205 rotates rightward around the third direction, so that the product B on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, so that the product B is moved along the Figure 1 The movement in the c direction shown drives the product B on the balance wheel 205 to continue to deflect and move relative to the second direction.

[0088] Similarly, at the third time, for example, the third time is 9s, but not limited thereto, and may also be 8.5s, 9.15s, 9.5s, etc. The speed change driving unit 204 increases the speed of all the balance wheels 205 in the third conveying area 220 to the third speed, the third time is greater than the second time, the third conveying area 220 includes the above-mentioned four rows of balance wheels 205, and the calculation method of the third time is the same as the second time, which will not be repeated here.

[0089] At the same time, the PLC issues a command to the direction change driving unit 203, and the direction change driving unit 203 drives the carrying portion 202 of the third conveying area 220 to rotate around the third direction, so as to drive the balance wheel 205 to rotate around the third direction, so that the product A on the balance wheel 205 is subjected to a force deflecting in the second direction relative to the forward movement, for example, the balance wheel 205 rotates to the left around the third direction, so that the product A on the balance wheel 205 is subjected to a force deflecting in the second direction relative to the forward movement, so that the product A is moved along the Figure 6 The movement in direction b shown is the conversion of the movement trajectory of product A into the movement trajectory of product A′, thereby driving the product A on the balance wheel 205 to deflect relative to the second direction, so that product A flows into the first sorting channel 103 .

[0090] Then, when product A leaves the third conveying area 220, product B is conveyed to the third conveying area 220. The PLC receives the signal and issues an instruction to the speed change drive unit 204 to drive the balance wheel 205 in the third conveying area 220 to return to the first speed and convey product B at the first speed.

[0091] At the same time, the PLC issues a command to the direction change driving unit 203, and the direction change driving unit 203 drives the carrying unit 202 of the third conveying area 220 to rotate around the third direction, so as to drive the balance wheel 205 to rotate around the third direction, so that the product B on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, for example, the balance wheel 205 rotates rightward around the third direction, so that the product B on the balance wheel 205 is subjected to a force of deflection in the second direction relative to the forward movement, so that the product B is moved along the Figure 1 The movement in the c direction shown drives the product B on the balance wheel 205 to deflect relative to the second direction, so that the product B flows into the second sorting channel 104.

[0092] Through the above process, when product A enters the first conveying area 218 and leaves the third conveying area 220, the balance wheel 205 conveys product A at the second speed, and when product B enters the first conveying area 218 and leaves the third conveying area 220, the balance wheel 205 conveys product B at the first speed, thereby increasing the distance between product A and product B. That is, when product A and product B leave the third conveying area 220, the distance between product A and product B is the second distance, for example, 500 mm, but not limited thereto, and may also be 450 mm, 490 mm, 600 mm, etc., which is greater than the distance of 400 mm between product A and product B before they enter the first conveying area 218.

[0093] However, it should be noted that the embodiment of the present application does not limit the specific number of conveying zones. It can be three conveying zones as shown in the embodiment of the present application, or it can be two, four, etc., as long as the distance between product A and product B can be increased.

[0094] First, a plurality of products are provided. The plurality of products are placed on the conveyor belt of the input channel 100 manually or by machine, and move along the input channel 100 at a first speed in sequence under the action of the conveyor belt; for example, the first speed is 2 m / s. A photoelectric sensor 300 is provided on the input channel 100. The plurality of products pass through the photoelectric sensor in sequence, and the signal is transmitted to the PLC. The PLC calculates the distance between two adjacent products according to the speed of the conveyor belt. For example, at this time, two adjacent products (i.e. Figure 7 The distance between product A and product B shown (i.e. Figure 7 The L1) shown is 470mm and the first distance is 450mm.

[0095] Determine two adjacent products among multiple products (i.e. Figure 7 The spacing between product A and product B shown in the figure is greater than the first distance, that is, 470 mm is greater than 450 mm, that is, the spacing between product A and product B is larger, and the PLC sends an instruction to the speed change drive unit 204 to drive the balance wheels 205 in the first conveying area 218, the second conveying area 219 and the third conveying area 220 to run at the first speed to convey product A and product B at the first speed.

[0096] In summary, the balance wheel drum can be divided into three conveying areas (i.e., the first conveying area 218, the second conveying area 219, and the third conveying area 220) according to the direction of product delivery, and each conveying area can independently accelerate the pulling distance. In the case where the spacing is small and is not conducive to sorting, the first package that arrives at the balance wheel can be accelerated, and the acceleration can be stopped before the next package arrives to achieve accelerated pulling distance. At the same time, it involves the configuration of the balance wheel drive card and the communication configuration. According to the balance wheel controlling different positions, the balance wheel drive card (i.e., the speed conversion drive unit 204) is dialed to configure the address, and the PLC is used to communicate the message to the balance wheel drive card to control its speed conversion to achieve sawing.

[0097] The photoelectric detection in front of the balance wheel detects whether the adjacent packages (such as the above-mentioned product A and product B) are too close to each other for judgment. If it is judged that they are too close, the PLC communicates with the balance wheel drive card (that is, the above-mentioned speed conversion drive unit 204) through a message to control its speed conversion to achieve sawing. If it is judged that they are not too close, it will operate normally without sawing.

[0098] It should be noted that the above-mentioned relevant data are only provided as examples for the convenience of understanding and can be adjusted accordingly according to actual work, and do not limit the scope of protection of this application.
