Background

Currently, in the global manufacturing industry field, the quality requirements of various enterprises on products produced by the enterprises are increasingly stringent, and the types of product detection are continuously increased. The introduction of a large number of automated inspection equipment is certainly the preferred strategy for large manufacturers in order to be able to control the quality of the product accurately. However, after the automated inspection equipment is introduced, enterprises face compatibility and matching problems in the process of implementing inspection, and the compatibility and matching problems exist between the automated inspection equipment and the original production line as well as between a plurality of automated inspection equipment. Because of the different design parameters of the devices, compatibility and matching issues are widespread.

The compatibility and matching problems are manifested by a plurality of problems such as size difference, running environment difference, data synchronization problem and the like, wherein the most important problem is the matching problem of the production rate and the detection rate, and the influence of the rate between devices caused by the failure of good matching is that the detection effect of the automatic detection device cannot reach the expected value and the quality control cannot be performed.

For example, in the tobacco production industry, as consumers have increasingly required appearance quality of products, cigarette manufacturers have introduced cigarette packet appearance detection devices for effectively controlling the appearance quality of cigarette packets. However, when the packaging machine runs at a high speed, the tobacco packages at the outlet of the packaging machine are closely arranged, so that the high-speed camera of the appearance detection device for the tobacco packages cannot capture images of two surfaces of the tobacco packages, corresponding detection tasks cannot be completed, and the accuracy of quality detection cannot be guaranteed.

As shown in fig. 3, the operation state of the first product arrangement device in embodiment 1 of the present invention is schematically shown. The adjusting device is connected with the elastic sheet structure to adjust the elastic range of the elastic sheet structure. In this embodiment, the adjustment means preferably comprises an adjustment screw set, a set of tightening nuts and a set of locking nuts. One end of the jacking nut group is connected with the adjusting screw group, and the other end is connected with the elastic piece structure in a contact way. The adjusting screw group adjusts the deformation of the elastic sheet structure by tightly pushing the nut group. The adjusting screw group is arranged on the fixed plate component. The locking nut group is sleeved on the adjusting screw group and used for locking the adjusting screw group.

Through holes are formed in both the first fixing plate 41 and the second fixing plate 42, and in this embodiment, the through holes are preferably screw holes for mounting the set of adjusting screws.

One end of the first jack nut 91 is connected to the first adjusting screw 81, and the other end of the first jack nut 91 abuts against the first elastic piece 61. The first tightening nut 91 is provided inside the first fixing plate 41. The first adjustment screw 81 compresses the first elastic piece 61 by driving the first jack nut 91, and the degree of compression of the first jack nut 91 to the first elastic piece 61 can be changed by adjusting the first screw 81. A second tightening nut 92 is disposed on the inside of the second fixed plate 42. One end of the second jack nut 92 is connected to the second adjusting screw 82, and the other end of the second jack nut 92 abuts against the second elastic piece 62. The second adjusting screw 82 compresses the second elastic sheet 62 by driving the second tightening nut 92, and the compression degree of the second tightening nut 92 to the second elastic sheet 62 can be changed by adjusting the second screw 82.

The lock nut assembly includes a first lock nut and a second lock nut, the first lock nut is sleeved on the first adjusting screw 81, the first lock nut is used for locking the position of the first adjusting screw 81, and the first lock nut is disposed at the outer side of the first fixing plate 41. A second locking nut is sleeved on the second adjusting screw 82, the second locking nut is used for locking the position of the second adjusting screw 82, and the second locking nut is arranged on the outer side of the second fixing plate 42.

Preferably, the contact end of the first tightening nut 91 contacting the first elastic sheet 61 is hemispherical, and the contact point of the first elastic sheet 61 contacting the first tightening nut 9 is located on the geometric center of the first elastic sheet body 64. The contact end of the second tightening nut 92 contacting the second elastic sheet 62 is hemispherical, and the contact point of the second elastic sheet 62 contacting the second tightening nut 92 is located on the geometric center of the second elastic sheet body 67. The first tightening nut 91 is coaxial with the second tightening nut 92. By adjusting the positions of the first and second adjustment screws 81 and 82, the width of the slow flow passage 7 at the position defined by the first and second jack nuts 91 and 92 can be changed. For example, if the product 5 is a tobacco packet, the width of the slow flow channel 7 at the position defined by the first tightening nut 91 and the second tightening nut 92 is adjusted to be 24±0.5mm.

The conveyor belt assembly 1 extends through the first inlet channel 23, the first outlet channel 33 and the slow flow channel 7. The conveying path of the conveyor device 1 passes through the first input passage 23, the slow flow passage 7, and the first output passage 33 in this order.

The working principle of the embodiment is as follows: first, closely spaced products 5 enter the first inlet channel 23 and are conveyed by the conveyor device 1 such that the closely spaced products 5 pass through the first inlet channel 23 in sequence into the slow flow channel 7. When the product 5 passes through the slow flow channel 7, the first elastic sheet 61 and the second elastic sheet 62 respectively act on the product 5, sliding friction is generated between the first elastic sheet 61 and the second elastic sheet 62 and two sides of the product 5, and the movement of the product 5 along the conveying direction of the conveyor belt device 1 is blocked by the friction force generated by the sliding friction. The product 5 of the slow flow path 7 is decelerated, and the passing speed of the product 5 in the slow flow path 7 is smaller than the conveying speed of the conveyor device 1.

When the product 5 continues to move to leave the slow flow channel 7, the product 5 enters the first output channel 33, and the product 5 is driven by the conveyor belt device 1 to accelerate, so that the distance between the product 5 and the product which is not separated from the slow flow channel 7 is pulled. This first product arrangement device has realized the function that peels off closely arranged product 5, and the interval between the product 5 when can also control the output simultaneously, and then realizes the product and arranges according to the demand.

The method of controlling the spacing between the products 5 at the time of output is: the first step controls the spacing between the first and second tightening nuts 91, 92 by adjusting the first and second adjusting screws 81, 82, i.e., adjusts the speed at which the product 5 passes within the slow flow channel 7.

The compression degree of the first elastic piece 61 and the second elastic piece 62 to the product 5 is controlled by adjusting the first adjusting screw 81 and the second adjusting screw 82 under the premise that the width of the slow flow channel 7 at the position defined by the first tightening nut 91 and the second tightening nut 92 is ensured to meet that the product 5 can pass through the slow flow channel 7. The smaller the distance between the first and second jack nuts 91, 92, the greater the degree of compression of the first and second elastic pieces 61, 62 against the product 5. If the distance between the first and second jack nuts 91, 92 is smaller, the greater the elastic stress of the first and second elastic pieces 61, 62 due to deformation is when the product 5 passes through the slow flow path 7, the greater the sliding friction force exerted by the first and second elastic pieces 61, 62 on the moving product 5 is, and the slower the product 5 passes through the slow flow path 7. Since the speed of the product 5 passing through the slow flow passage 7 is a controllable variable, the control of the speed of the product 5 passing through the slow flow passage 7 can affect the product pitch at the time of output.

In a second step, the conveying rate of the conveyor belt device 1 is adjusted.

Through the two steps, the purpose of controlling the spacing of the products 5 during output can be achieved. The two steps have no time sequence requirement in the implementation process. The two steps may be alternatively or jointly performed without considering the time sequence.

Example 2

This embodiment differs from embodiment 1 in that: the side of the first elastic sheet 61 close to the second elastic sheet 62 is provided with a rubber gasket, and the side of the second elastic sheet 62 close to the first elastic sheet 61 is also provided with a rubber gasket. The beneficial effects are that: the speed reduction effect on the product 5 in the slow flow channel 7 is increased, the buffer effect is achieved, and the probability of mechanical damage to the product 5 caused by the elastic sheet structure is reduced.

The working principle of the embodiment is as follows: firstly, an air pump is used for inflating the first air bag 51 and the second air bag 52, the width of the narrowest part of the slow flow channel 7 is not larger than the width of the first input channel 23, then the closely arranged products 5 enter the first input channel 23, and the closely arranged products 5 sequentially pass through the first input channel 23 and enter the slow flow channel 7 after being conveyed by the conveyor belt device 1. When the product 5 passes through the slow flow passage 7, the first air bag 51 and the second air bag 5 respectively act on the product 5, sliding friction is generated between the first air bag 51 and the second air bag 5 and two sides of the product 5 respectively, and the movement of the product 5 along the conveying direction of the conveyor belt device 1 is hindered by friction force generated by the sliding friction. The product 5 of the slow flow path 7 is decelerated, and the passing speed of the product 5 in the slow flow path 7 is smaller than the conveying speed of the conveyor device 1.

The method of controlling the spacing between the products 5 at the time of output is:

In the first step, the speed of the product 5 passing through the slow flow passage 7 is controlled by adjusting the amount of inflation of the air pump to the first air bag 51 and the second air bag 52. On the premise of ensuring that the product 5 can pass through the slow flow channel 7, the compression degree of the first air bag 51 and the second air bag 52 on the product 5 is controlled by adjusting the inflation amount of the first air bag 51 and the second air bag 52. When the product 5 passes through the slow flow passage 7, if the inflation amount of the first air bag 51 and the second air bag 52 is larger, the contact area between the product 5 and the first air bag 51 and the second air bag 52 is larger, the pressure exerted by the first air bag 51 and the second air bag 52 on the product 5 is larger, and the sliding friction force exerted by the first air bag 51 and the second air bag 52 on the moving product 5 is larger, so that the speed of the product 5 passing through the slow flow passage 7 is slower. Since the speed of the product 5 passing through the slow flow passage 7 is a controllable variable, the control of the speed of the product 5 passing through the slow flow passage 7 can affect the product pitch at the time of output.

In a second step, the conveying rate of the conveyor belt device 1 is adjusted.

Example 4

This embodiment differs from embodiment 3 in that: the first product arrangement device further comprises a control device, a product interval detection device and an interaction device. The control device is electrically connected with the product interval detection device, the interaction device, the adjusting device and the conveying device respectively. In this embodiment, the conveying device is preferably a conveyor device 1, and the adjusting device is preferably an air pump. The interval detecting device is used for detecting the interval between the products 5 in the first output channel 33 and feeding back interval information of the products 5 to the control device. The distance detection device and the control device together form a feedback system. The interaction device is used for providing a human-computer interaction path, and an operator can check and set the operation parameters of the first product arrangement device through the interaction device. In this embodiment, the operating parameters of the first product arrangement include the transfer rate of the conveyor device 1 and the amount of inflation of the first and second air bags 51, 52.

The control means controls the first product arrangement means, in particular the spacing between the products 5 at the output, in dependence on the first product arrangement means operating parameters set in the interaction means.

The method of controlling the spacing between the products 5 at the time of output is: the control device simultaneously controls the conveying rate of the conveyor belt device 1 and the inflation amount to the first airbag 51 and the second airbag 52 so that the interval between the products 5 at the time of output reaches a set value. The control device also compares the set value of the product pitch with the actual measured value, and adjusts the conveyance rate of the conveyor belt device 1 and the inflation amount to the first air bag 51 and the second air bag 52 if a deviation occurs.

Example 5

Fig. 5 is a schematic structural view of a first product arrangement device in embodiment 5 of the present invention. The first product arrangement device provided in embodiment 5 of the present invention includes:

The fixing plate assembly includes a first fixing plate 41 and a second fixing plate 42, the first fixing plate 41 being connected with the first input side plate 21 and the first output side plate 31, respectively, and the second fixing plate 42 being connected with the second input side plate 22 and the second output side plate 32, respectively. The first and second fixing plates 41 and 42 are provided with through holes, respectively.

The slow flow device is a compression elastic piece symmetrically arranged at two sides of the conveyor belt device 1. In this embodiment, the slow flow device is preferably an elastic bag structure having a shear thickening fluid therein, and the elastic bag structure includes a first elastic bag 71 and a second elastic bag 72. The first elastic pocket 71 is installed at a side of the first fixing plate 41 adjacent to the second fixing plate 42. The front end of the first elastic bag 71 is detachably connected between the first input-end side plate 21 and the first fixing plate 41. The rear end of the first elastic bag 71 is detachably connected between the first output end side plate 31 and the first fixing plate 41. The second elastic pocket 72 is installed at a side of the second fixing plate 42 adjacent to the first fixing plate 41. The front end of the second elastic bag 72 is detachably connected between the second input-side plate 22 and the second fixing plate 42. The second elastic bag 72 is detachably connected at the rear end between the second output end side plate 32 and the second fixing plate 42. A slow flow passage 7 is formed between the first elastic bag 71 and the second elastic bag 72. The maximum width of the slow flow channel 7 is not greater than the width of the first input channel 23. The first elastic bag 71 and the second elastic bag 72 each have a D-shaped profile in the slow flow passage 7. The first elastic bag 71 and the second elastic bag 72 are arranged opposite to each other, so that the width of the slow flow channel 7 is in a non-fixed gradual change state.

The shear thickening fluid inside the first and second elastic bags 71, 72 comprises, in mass percent: 0.2 to 3.3 percent of polyethylene oxide, 0.5 to 2.2 percent of nano silicon dioxide colloidal particles and the balance of deionized water. The shear thickening fluid has the beneficial effects that: the particles in the shear thickening fluid do not settle, and the dispersion effect is good, and the reason is that:

1. The nano silicon dioxide colloidal particles have the same negative charge, the colloidal particles are mutually repelled, and large particle precipitates cannot be aggregated among the colloidal particles to be separated out from the dispersing agent.

2. The colloidal particles are small, the weight is light, and the self Brownian movement can overcome the sedimentation effect caused by gravity.

3. The nano silica gel particles can adsorb polyethylene oxide molecules, and because a large number of ether bonds exist on the molecular chain of the polyethylene oxide, C-O bonds can be broken and hydrolyzed into hydroxyl groups, and the hydroxyl groups have negative charges, the polyethylene oxide molecules can have repulsive interaction.

The viscosity of the shear thickening fluid in the first and second elastic bags 71 and 72 increases with the increase of the shear rate of the product 5, that is, the greater the original speed of the product 5 entering the slow flow channel 7, the greater the viscosity of the shear thickening fluid, the greater the resistance generated by the shear thickening fluid, and the more obvious the deceleration effect of the shear thickening fluid on the product 5, with the constant addition of the shear thickening fluid in the first and second elastic bags 71 and 72.

The elastic bag structure containing the shear thickening fluid has the advantages of being good in elasticity, high in impact strength, good in ageing resistance and good in antifriction and wear resistance. The resilient bag structure, which contains the shear thickening fluid inside, can increase the durability of the device, reduce the chance of mechanical damage to the product 5, and in addition, can be easily controlled.

The adjusting device is connected with the elastic bag structure to adjust the elastic range of the elastic bag structure. In this embodiment, preferably, the adjusting means is injection means, which communicates with the first elastic bag 71 through a through hole in the first fixing plate 41; the injection means is also in communication with the second elastic bag 72 through a through hole in the second fixing plate 42, and is used for injecting the shear thickening fluid into the first and second elastic bags 71 and 72.

The working principle of the embodiment is as follows: firstly, the shear thickening fluid is injected into the first elastic bag 71 and the second elastic bag 72 by using an injection device, so that the width of the narrowest part of the slow flow channel 7 is not larger than the width of the first input channel 23, then the closely arranged products 5 enter the first input channel 23, and the closely arranged products 5 sequentially enter the slow flow channel 7 through the first input channel 23 by being conveyed by the conveyor belt device 1. When the product 5 passes through the slow flow passage 7, the first and second elastic bags 71 and 72 and the shear thickening fluid therein respectively act on the product 5, the first and second elastic bags 71 and 72 respectively generate sliding friction with both sides of the product 5, and the movement of the product 5 in the conveying direction of the conveyor belt device 1 is hindered by friction force generated by the sliding friction and resistance from the shear thickening fluid. The product 5 of the slow flow path 7 is decelerated, and the passing speed of the product 5 in the slow flow path 7 is smaller than the conveying speed of the conveyor device 1. The greater the original velocity of the product 5 entering the slow flow channel 7, the greater the viscosity of the shear thickening fluid, and the more pronounced the retarding effect of the first and second elastic bags 71, 72 on the product 5.

One method of controlling the pitch of the product 5 at output is: the conveying rate of the conveyor belt device 1 is adjusted. The greater the conveying rate of the conveyor belt device 1, the greater the resistance of the shear thickening fluid to the products 5, the more pronounced the decelerating effect of the shear thickening fluid on the products 5, the greater the spacing of the products 5 at the time of output, with the amount of shear thickening fluid added inside the first and second elastic bags 71, 72 unchanged. The conveyor belt device 1 has a reduced conveying rate, the resistance of the shear thickening fluid to the products 5 is reduced, and the product 5 pitch at the time of output is reduced.

Another method of controlling the pitch of the product 5 at output is: the addition of the shear thickening fluid in the flexible bag structure was adjusted. The contact area between the product 5 and the first and second elastic bags 71 and 72 can be changed by adjusting the addition amount of the shear thickening fluid, and the larger the contact area is, the stronger the deceleration effect of the first and second elastic bags 71 and 72 on the product 5 is; the smaller the contact area, the weaker the decelerating effect of the first and second elastic bags 71 and 72 on the product 5.

In addition, the two methods for controlling the spacing between the products 5 during output provided in this embodiment may be used in combination. The conveying speed of the conveying belt device 1 is regulated, and the addition amount of the shear thickening fluid in the elastic bag structure is regulated so as to achieve the purpose of controlling the spacing of the products 5 during output. The adjustment of the conveying rate of the conveyor belt device 1 and the addition amount of the shear thickening fluid in the elastic bag structure is not sequential, and has no time sequence requirement.

Example 6

This embodiment differs from embodiment 5 in that: the first product arrangement device provided in this embodiment further includes a control device, a product interval detection device, and an interaction device. The control device is electrically connected with the product interval detection device, the interaction device, the adjusting device and the conveying device respectively. In this embodiment, the conveyor is preferably a conveyor 1 and the adjustment device is preferably an injection device. The interval detecting device is used for detecting the interval between the products 5 in the first output channel 33 and feeding back interval information of the products 5 to the control device. The distance detection device and the control device together form a feedback system. The interaction device is used for providing a human-computer interaction path, and an operator can check and set the operation parameters of the first product arrangement device through the interaction device. In this embodiment, the operating parameters of the first product arrangement include the transfer rate of the conveyor means 1 and the amount of shear thickening fluid added to the flexible bag structure. The control means controls the first product arrangement means, in particular the spacing between the products 5 at the output, in dependence on the first product arrangement means operating parameters set in the interaction means.

The control device simultaneously controls the conveying rate of the conveyor belt device 1 and the addition amount of the shear thickening fluid in the elastic bag structure so that the spacing between the products 5 at the time of output reaches a set value. The control device also compares the set value of the product pitch with the actual measured value, and if a deviation occurs, the conveying rate of the conveyor belt device 1 and the addition amount of the shear thickening fluid in the elastic bag structure are adjusted by the control device.

In the present embodiment, the number of throttle modules 701 in the throttle device is preferably 3, and the throttle modules 701 are provided on the support housing 601. The throttle module 701 includes a U-shaped mounting fork 801, a fixing lever 802, an elastic member, and a roller 703. The resilient member in this embodiment is preferably a spring 702. The roller 703 is connected with the U-shaped mounting fork 801 through a pin shaft. The spring 702 is sleeved on the fixed rod 802. FIG. 10 is a schematic view showing the structure of a U-shaped mounting fork according to embodiment 7 of the present invention; the U-shaped mounting fork 801 is fixedly connected with the fixing rod 802.

The roller 703 is disposed between the U-shaped mounting fork first side plate 804 and the U-shaped mounting fork second side plate 805. A U-shaped mounting fork top plate 803 is mounted between the support housing first side plate 604 and the support housing second side plate 605. The roller fixing bolt is connected with the roller 703 through a U-shaped mounting fork first side plate through hole 806. The roller fixing bolt is connected to the roller 703 through a through hole 807 of the second side plate of the U-shaped mounting fork. The roller 703 is rotatable along a rotational axis defined by the U-shaped mounting fork first side plate through hole 806 and the U-shaped mounting fork second side plate through hole 807.

The lower end of the fixed rod 802 is fixedly connected with a U-shaped mounting fork top plate 803. The spring 702 is sleeved on the fixed rod 802. One end of the spring 702 abuts against the U-shaped mounting fork top plate 803, and the other end abuts against the support housing top plate 603.

Fig. 11 is a schematic view showing an operation state of the second product arrangement device in embodiment 7 of the present invention. The working principle of the embodiment is as follows: first, closely spaced products 5 enter the first product channel 501 and are conveyed by the product conveyor 201 such that closely spaced products 5 pass through the first product channel 501 and enter the deceleration channel 503. As the product 5 passes through the deceleration channel 503, rollers 703 above the deceleration channel 503 act on the product 5 from the top end of the product 5 such that the product 5 is pinched between the rollers 703 and the product conveyor 201. The product 5 generates a pushing force on the throttle module 701, pushing the throttle module 701 upward, and the spring 702 is further compressed. The resultant force of the spring 702 and the gravity of the throttle module 701 acts on the product 5 to compress the product 5, so that sliding friction force is generated between the product 5 and the roller 703. The sliding friction force hinders the movement of the product 5 in the conveying direction of the product conveying device 201. The product 5 in the deceleration path 503 is decelerated, and the passing speed of the product 5 in the deceleration path 503 is smaller than the conveying speed of the product conveying device 201.

When the product 5 continues to move to leave the deceleration channel 503, the product 5 enters the second product channel 502, the product 5 is driven by the product conveying device 201 to accelerate, the distance between the product 5 and the product which is not separated from the deceleration channel 503 later is further pulled, the second product arrangement device realizes the function of stripping the closely arranged product 5, and meanwhile, the distance between the products 5 during output can be controlled, so that the function of arranging the products according to requirements is realized.

The method of controlling the spacing between the products 5 at the time of output is: the adjusting nut 808 is screwed or loosened to adjust the distance between the U-shaped mounting fork 801 and the product conveying device 201, that is, the distance between the roller 703 and the product conveying device 201 is adjusted by screwing or loosening the adjusting nut 808, so as to control the compression degree of the roller 703 on the product 5. The greater the degree of compression of the product 5 by the roller 703, the longer the product 5 passes through the deceleration channel 503, and the greater the spacing of the products 5 within the second product channel 502, and vice versa.

Another method of controlling the spacing between products 5 at output is: the conveyance rate of the product conveyor 201 is adjusted.

By the two methods for controlling the spacing between the products 5 during output provided in this embodiment, the purpose of controlling the spacing between the products 5 during output can be achieved. The two methods have no time sequence requirement in the implementation process. The two methods can be alternatively implemented, or can be implemented together without considering time sequence.

In this embodiment, the number of the throttling modules 701 in the throttling device is preferably 3, and the compression degree of each roller 703 on the product 5 is set to be different, so that the 3 throttling modules 701 can perform the sectional deceleration on the product 5, thereby not only obtaining a stable deceleration effect, but also easily controlling the spacing of the products 5 entering the second product channel 502. In addition, the probability of mechanical damage to the product 5 is reduced.

Example 8

This embodiment differs from embodiment 7 in that: in this embodiment, the number of the throttling modules 701 in the throttling device is preferably 1, which has the beneficial effects that the product arrangement function can be realized, and meanwhile, the structure is compact, and the throttling device is suitable for the situation that the space in the installation environment is limited.

Example 9

This embodiment differs from embodiment 7 in that: a rubber gasket is provided on the outer side of the roller 703. The beneficial effects are that: the speed reducing effect on the product 5 in the speed reducing channel 503 is increased, the buffer function is achieved, and the probability of mechanical damage to the product 5 caused by the roller 703 is reduced.

Example 10

This embodiment differs from embodiment 7 in that: the second product arrangement device further comprises a pump body structure, and the pump body structure is a first pump body in the embodiment. The periphery of the roller 703 is annularly coated with an elastic bag body, in this embodiment, the elastic bag body is a roller air bag, and preferably, the roller air bag is made of high-strength polyamide fiber coated with silicone rubber or neoprene high-strength polyamide fiber. The advantages are that: the air bag made of the high-strength polyamide fiber coated with the silicone rubber or the chloroprene rubber high-strength polyamide fiber has the characteristics of good elasticity, high impact strength, good ageing resistance and good antifriction and wear resistance. The first pump body is communicated with the roller air bag and is used for adjusting the inflation amount in the roller air bag.

The working principle of the embodiment is as follows: first, in preparation for operation, the adjustment nut 808 is tightened or loosened, and the amount of inflation of the first pump body to the roller bladder is adjusted to bring the roller 703 into position. Then, closely spaced products 5 begin to enter the first product channel 501 and pass through the product conveyor 201, causing closely spaced products 5 to pass through the first product channel 501 and into the deceleration channel 503.

As the product 5 passes through the deceleration channel 503, rollers 703 above the deceleration channel 503 act on the product 5 from the top end of the product 5 such that the product 5 is pinched between the rollers 703 and the product conveyor 201. The product 5 generates a thrust force on the throttle module 701, the thrust force compresses the roller air bag, the thrust force also pushes the throttle module 701 to move upwards, and the spring 702 is further compressed. The resultant force of the spring 702, the air pressure in the roller air bag and the gravity of the throttle module 701 acts on the product 5 to compress the product 5, so that sliding friction force is generated between the product 5 and the roller 703. The sliding friction force hinders the movement of the product 5 in the conveying direction of the product conveying device 201. The product 5 in the deceleration path 503 is decelerated, and the passing speed of the product 5 in the deceleration path 503 is smaller than the conveying speed of the product conveying device 201.

One way to control the spacing between products 5 at output is to:

In the first step, the adjusting nut 808 is screwed or loosened to adjust the distance between the U-shaped mounting fork 801 and the product conveying device 201, that is, the distance between the roller 703 and the product conveying device 201 is adjusted by screwing or loosening the adjusting nut 808, so as to control the compression degree of the roller 703 on the product 5. The greater the degree of compression of the product 5 by the roller 703, the longer the product 5 passes through the deceleration channel 503, and the greater the spacing of the products 5 within the second product channel 502, and vice versa.

In the second step, the speed of the product 5 passing through the deceleration channel 503 is controlled by adjusting the inflation amount of the first pump body to inflate the roller air bag. The larger the inflation amount of the first pump body for inflating the roller air bag, the larger the contact area between the roller air bag and the product 5, and the larger the gas pressure inside the roller air bag. Therefore, the degree of compression of the roller air bag on the product 5 can be controlled by adjusting the air charging amount of the first pump body for charging the roller air bag. The greater the sliding friction of the roller bladder against the moving product 5, the slower the speed of the product 5 through the deceleration channel 503. The speed of the product 5 through the deceleration channel 503 is a controllable variable, and therefore, control of the speed of the product 5 passing through the deceleration channel 503 can affect the product pitch at the time of output.

Third, the transfer rate of the product conveyor 201 is adjusted.

Through the three steps, the purpose of controlling the spacing of the products 5 during output can be achieved. The three steps have no time sequence requirement in the implementation process. The three steps can be alternatively implemented, or can be implemented in any combination without considering the time sequence.

Example 11

This embodiment differs from embodiment 10 in that: the second product arrangement device further comprises central control equipment, a laser ranging device and a man-machine interaction device. The central control device is electrically connected with the laser ranging device, the man-machine interaction device, the first pump body and the product conveying device 201 respectively, and the laser ranging device is used for detecting the distance between the products 5 in the second product channel 502 and feeding back the distance information of the products 5 to the central control device. The central control device and the laser ranging device together form a feedback system. The man-machine interaction device is used for providing a man-machine interaction path, and an operator can check and set the operation parameters of the second product arrangement device through the man-machine interaction device.

In this embodiment, the operating parameters of the second product arrangement include the transfer rate of the product conveyor 201 and the amount of inflation of the roller bladder. The central control device controls the second product arrangement device according to the operation parameters of the second product arrangement device set in the man-machine interaction device, and particularly controls the interval between products 5 during output.

One way to control the spacing between products 5 at output is to: the central control device simultaneously controls the conveying rate of the product conveying device 201 and the inflation amount in the roller air bags so that the distance between the products 5 at the output time reaches a set value. The central control device also compares the set value of the product interval with the actual measured value, and if deviation occurs, adjusts the conveying rate of the product conveying device 201 and the inflation amount in the roller air bag.

the second product arrangement device further comprises a pump body structure, and the pump body structure is a second pump body in the embodiment. The periphery of the roller 703 is annularly coated with an elastic bag, in this embodiment, the elastic bag is a roller-wheel fluid bag, and the interior of the roller-wheel fluid bag is filled with a shear thickening fluid. The second pump body is communicated with the roller fluid bag and is used for adjusting the addition amount of the shear thickening fluid in the roller fluid bag.

The shear thickening fluid inside the roller rotor fluid bag comprises the following components in percentage by mass: 0.2 to 3.3 percent of polyethylene oxide, 0.5 to 2.2 percent of nano silicon dioxide colloidal particles and the balance of deionized water. The shear thickening fluid has the beneficial effects that: the particles in the shear thickening fluid do not settle, and the dispersion effect is good, and the reason is that:

The viscosity of the shear thickening fluid in the roller rotor fluid bags increases with the increase of the shear rate of the product 5, that is, the greater the original speed of contact between the product 5 and the roller fluid bags, the greater the viscosity of the shear thickening fluid, the greater the friction coefficient of the shear thickening fluid, and the more obvious the deceleration effect of the shear thickening fluid on the product 5, under the condition that the addition amount of the shear thickening fluid in the roller rotor fluid bags is unchanged.

The roller fluid bag containing the shear thickening fluid has the advantages of being good in elasticity, high in impact strength, good in ageing resistance and good in antifriction and wear resistance. The roll-in-roll fluid bladder, which contains a shear thickening fluid therein, can increase the durability of the device, reduce the chance of mechanical damage to the product 5, and in addition, can be easily controlled.

The working principle of the embodiment is as follows: first, in preparation for operation, the adjustment nut 808 is tightened or loosened, and the amount of shear thickening fluid added to the interior of the roller wheel fluid pockets is adjusted, so that the roller 703 is in place. The closely spaced products 5 then begin to enter the first product channel 501 and pass through the product conveyor 201, causing the closely spaced products 5 to pass through the first product channel 501 and into the deceleration channel 503.

As the product 5 passes through the deceleration channel 503, rollers 703 above the deceleration channel 503 act on the product 5 from the top end of the product 5 such that the product 5 is pinched between the rollers 703 and the product conveyor 201. The product 5 generates a thrust on the throttling module 701, which acts on the roller-wheel fluid pockets, which also pushes the throttling module 701 upwards, the spring 702 being further compressed. The resultant force of the spring 702 and the gravity of the throttle module 701 acts on the product 5 to compress the product 5, so that sliding friction force is generated between the product 5 and the roller-rotor fluid bag. The sliding friction force hinders the movement of the product 5 in the conveying direction of the product conveying device 201. The product 5 in the deceleration path 503 is decelerated, and the passing speed of the product 5 in the deceleration path 503 is smaller than the conveying speed of the product conveying device 201.

One way to control the spacing between products 5 at output is to:

In the second step, the rate of passage of the product 5 in the deceleration channel 503 is controlled by adjusting the amount of shear thickening fluid added inside the roller-wheel fluid bladder. The contact area of the product 5 and the roller-wheel fluid bags can be changed by adjusting the addition amount of the shear thickening fluid, and the larger the contact area is, the stronger the resistance and the deceleration effect of the roller-wheel fluid bags on the product 5 are; the smaller the contact area, the weaker the roller fluid pockets will have resistance and deceleration effects on the product 5. Control of the speed at which the product 5 passes within the deceleration channel 503 can affect the product pitch at the time of output.

Third, the transfer rate of the product conveyor 201 is adjusted. The greater the transfer rate of the product conveyor 201, the greater the initial speed at which the product 5 contacts the roller fluid pockets, the greater the viscosity of the shear thickening fluid, the greater the coefficient of friction of the shear thickening fluid, the greater the sliding friction of the roller fluid pockets against the product 5, the greater the retarding effect of the shear thickening fluid against the product 5, and vice versa, with the constant amount of shear thickening fluid added inside the roller fluid pockets.

Through the three steps, the purpose of controlling the spacing of the products 5 during output can be achieved. The three steps have no time sequence requirement in the implementation process. The three steps may be alternatively or jointly performed without considering the time sequence.

The central control device and the laser ranging device together form a feedback system. The man-machine interaction device is used for providing a man-machine interaction path, and an operator can check and set the operation parameters of the second product arrangement device through the man-machine interaction device.

In this embodiment, the operating parameters of the second product arrangement include the rate of delivery of the product conveyor 201 and the amount of shear thickening fluid added to the interior of the roll fluid pockets. The central control device controls the second product arrangement device according to the operation parameters of the second product arrangement device set in the man-machine interaction device, and particularly controls the interval between products 5 during output.

One way to control the spacing between products 5 at output is to: the central control device simultaneously controls the conveying rate of the product conveying device 201 and the addition amount of the shear thickening fluid in the roller wheel fluid bags so that the interval between the products 5 at the output time reaches a set value. The central control device also compares the set value of the product interval with the actual measured value, and if deviation occurs, adjusts the conveying rate of the product conveying device 201 and the addition amount of the shear thickening fluid in the roller-wheel fluid bags.
