[0031] 3. In scheme three and its preferred implementation, the control member sequentially obtains the sensing information of the sensing member in the opposite direction of the first direction, and controls the state of the driving member according to the sensing information of each sensing member, so that the sensing member on the side close to the next workstation is actuated first, which can speed up work efficiency.

[0032] 4. In scheme 4 and its preferred implementation, the control member is also suitable for obtaining the amount of materials within the first spacing, and controlling each driving member when the amount of materials within the first spacing is equal to a threshold value, so as to adjust the transfer speed of each of the transfer members, and adjust the transfer speed of each transfer member to increase or decrease according to the working state of the next station. If it is working, the transfer speed of all or part of the transfer members is reduced to prevent collision. If it is in a state of waiting for incoming materials, the transfer speed of all or part of the transfer members is accelerated to speed up the beat, so as to prevent the harm caused by further accumulation of materials when the materials are about to accumulate. Of course, it can also be adjusted according to the above method, that is, when there is material on the transfer member, the transfer speed of the previous transfer member is increased, and when there is no material on the transfer member, the transfer speed of the previous transfer member is reduced, so that the amount of materials within the first spacing is equal to the threshold value to reduce material accumulation.

[0033] 5. In scheme five and its preferred implementation manner, the sensing element comprises a first counting element and a second counting element, the spacing between the first counting element and the second counting element is a first spacing, the size of a single material is obtained and a threshold is obtained based on the size of the single material and the first spacing, and the threshold is obtained by using the original sensing element, which is simple and convenient; the number of materials within the first spacing is obtained by calculating the difference between the number of materials passing through the first counting element and the second counting element, and the number of materials within the first spacing is obtained by using the original sensing element, which is simple, convenient, and has a small amount of calculation and is relatively simple.

[0034] 6. In scheme six and its preferred implementation manner, each transfer member is tilted downward along the same side perpendicular to the first direction, so as to facilitate the materials to be located on the same side, which is convenient for subsequent workstation actions.

[0036] 8. In scheme eight and its preferred implementation manner, the sensing element on the rear side is arranged close to the transfer element, and the control element is suitable for calculating the number of materials passing through the sensing element on the rear side, and when the number of materials passing through the sensing element on the rear side reaches the single pushing number, the pushing element is controlled to push the materials, so that the pushing element can push multiple materials at the same time, thereby reducing the working frequency of the pushing element and increasing work efficiency.

In scheme nine and its preferred implementation, the single push quantity is obtained according to the size of a single material and the size of the transfer piece, or the single push quantity is obtained according to the size of a single material and the size of the pushing piece, which is simple and convenient.

[0038] 10. In scheme ten and its preferred embodiment, a conveying device includes at least two transfer members, a driving member, a sensing member and a control member. Each transfer member is arranged in sequence along a first direction, and transfers the materials thereon in sequence along the first direction. The number of driving members is the same as the number of transfer members, and they correspond one to one to control the transfer speed of each transfer member, so that the transfer speed of each transfer member is independent.

[0039] 11. In the eleventh scheme and its preferred embodiment, a control method for a transfer member senses whether there is material on a transfer member. When there is no material on the transfer member, the transfer speed of the previous transfer member is increased; when there is material on the transfer member, the transfer speed of the previous transfer member is reduced.

In addition, the sensing method is used to obtain whether there is material on the transfer member, which does not require a lot of analysis and is simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] refer to Figure 1 , Figure 2 A conveying device includes a transfer member 1, a driving member 2, a sensing member 3, a control member (not shown in the figure), a transfer member 4, a conveying member 5 and a pushing member 6.

[0053] The output member is connected to the conveying device, and the output member is suitable for outputting materials along the first direction 7 to the frontmost transfer member 1. In this embodiment, the frontmost transfer member 1 is Figure 1 The leftmost transfer member 1; in this embodiment, the output member is an edge banding machine for performing edge banding processing on the plate.

[0054] The transfer member 1 is used to sequentially transfer the materials thereon along the first direction 7. Each transfer member 1 is tilted downward along the same side perpendicular to the first direction 7 so that the materials slide to the same side of the transfer member 1 due to their own gravity, thereby facilitating the transmission and subsequent pushing of the pushing member 6. There are at least two transfer members 1, and each transfer member 1 is sequentially arranged along the first direction 7. In this embodiment, the transfer member 1 can be a roller, or a conveyor belt composed of a roller and a belt. In this embodiment, there are four transfer members 1. The transfer member 1 on the rear side is suitable for conveying materials to the transfer member 4.

[0055] Drive 2 (in Figure 3 The number of the transfer members 1 is the same as that of the transfer members 1 and corresponds one to one to control the transfer speed of each transfer member 1, so that the transfer speeds of the transfer members 1 can be independent of each other and will not affect each other.

[0056] There are several groups of sensing elements 3, and they are used to sense whether there is material on each transfer element 1. One transfer element 1 may be provided with only one group of sensing elements 3, or may be provided with two or more groups of sensing elements 3. The sensing element 3 may sense whether there is material on only a part of the transfer element 1, or may sense whether there is material on the entire transfer element 1. The sensing element 3 may be a through-beam sensor (including a transmitting end 31 and a receiving end 32), a distance sensor, a capacitive sensor, a photoelectric sensor, etc., and the sensing direction may be a horizontal direction (such as Figure 1 ), vertical direction (such as Figure 3 , Figure 4 ). Specifically, Figure 1 There are five sensors, which are the initial position photoelectric sensor (the leftmost sensing element 3), the first beam sensor, the second beam sensor, the third beam sensor and the fourth beam sensor in sequence along the first direction 7, wherein the first beam sensor and the fourth beam sensor are the first counting element and the second counting element respectively, and the first counting element and the second counting element can respectively count the passing materials. The third beam sensor and the fourth beam sensor correspond to the last transfer element 1 at the same time, and the fourth beam sensor is the last sensing element 3 and is arranged close to the transfer element 4. The spacing between the first counting element and the second counting element is the first spacing 33.

[0057] The transfer member 4 connects the rearmost transfer member 1 and the conveying member 5 . The transfer member 4 is suitable for receiving the material conveyed by the rearmost transfer member 1 and allowing the material to enter the conveying member 5 .

[0058] The conveying member 5 is suitable for transferring materials thereon along a second direction 8 , and its structure may be the same as that of the transferring member 1 . In this embodiment, the second direction 8 is perpendicular to the first direction 7 .

[0059] The pushing member 6 is suitable for pushing the material on the transfer member 4 onto the conveying member 5 along the second direction 8 .

[0060] Before the device is turned on, the size of a single material is obtained by user input or by importing drawings. In this embodiment, the size of the material along the first direction 7 is obtained, and a threshold is obtained according to the size of the single material and the first spacing 33. The threshold is the maximum number of materials stored in the first spacing 33. If the size of a single material is a, the size of the first spacing 33 is b, and the reasonable interval between adjacent materials is c, then the threshold = b / (a+c), and it is rounded down.

[0061] The single push quantity is obtained according to the size of the single material and the size of the transfer member 4 (the size along the first direction 7). For example, if the size of the single material is a and the size of the transfer member 4 is d, the single push quantity = d / a, and round down. Or, the single push quantity is obtained according to the size of the single material and the size of the push member 6 (the size along the first direction 7). For example, if the size of the single material is a and the size of the transfer member 4 is e, the single push quantity = e / a, and round down. In other embodiments, the threshold and the single push quantity can also be set directly.

[0062] In normal use, the control element is suitable for controlling the previous driving element 2 to increase the transfer speed of the previous transfer element 1 when a sensing element 3 senses that there is material on the corresponding transfer element 1. The control element is suitable for controlling the previous driving element 2 to reduce the transfer speed of the previous transfer element 1 when a sensing element 3 senses that there is no material on the corresponding transfer element 1. The control element sequentially obtains the sensing information of the sensing elements 3 in the opposite direction of the first direction 7, and controls the state of the driving element 2 according to the sensing information of each sensing element 3, that is, first obtains whether there is material on the last transfer element 1, and if there is no material, controls the third transfer element 1 to accelerate, and at the same time determines whether there is material on the third transfer element 1, and if there is still no material, controls the second transfer element 1 to accelerate.

[0063] During operation, the controller also obtains the number of materials within the first spacing 33 by calculating the difference between the number of materials passing through the first counting piece and the second counting piece. For example, if the number of materials passing through the second counting piece is X and the number of materials passing through the first counting piece is Y, then the number of materials within the first spacing 33 is YX. The number of materials passing through can be determined by the on and off times of the sensing signal of the first counting piece.

[0064] The control unit also controls each driving unit 2 to adjust the transfer speed of each transfer unit 1 when the amount of material within the first spacing 33 is equal to the threshold value. The transfer speed of each transfer unit 1 can be adjusted to increase or decrease according to the working state of the next station. If the next station is working, the transfer speed of all or part of the transfer units 1 is reduced to prevent collision. If the next station is in a state of waiting for incoming materials, the transfer speed of all or part of the transfer units 1 is accelerated to speed up the beat. The working state of the next station can be determined by the instructions of the control unit. In other embodiments, the adjustment can also be carried out according to the above method, that is, when there is material on the transfer unit 1, the transfer speed of the previous transfer unit 1 is increased, and when there is no material on the transfer unit 1, the transfer speed of the previous transfer unit 1 is reduced, so that the amount of material within the first spacing 33 is equal to the threshold value to reduce material accumulation. Furthermore, the control member is adapted to control the output member to stop when the amount of materials within the first spacing 33 is equal to a threshold value and the first sensing member 3 (ie, the initial position photoelectric sensor) senses that there is material on the frontmost transfer member 1 .

[0065] The control component is suitable for calculating the amount of materials passing through the sensing component 3 on the rear side, and when the amount of materials passing through the sensing component 3 on the rear side (the fourth corresponding sensor) reaches the single push amount and the push will not collide with the machine, the push component 6 is controlled to push the materials so that the materials enter the conveying component 5 from the transfer component 4.

[0066] The combination of the transfer member 1, the driving member 2, the sensing member 3 and the control member can be used for both loading and unloading of materials, by sensing whether there is material on a transfer member 1. When there is material on the transfer member 1, the transfer speed of the previous transfer member 1 is increased; when there is no material on the transfer member 1, the transfer speed of the previous transfer member 1 is reduced. In some embodiments, the reduction in transfer speed also includes reducing it to zero to increase the working rhythm or protect the device.

[0067] Compared with the prior art, this embodiment has the following beneficial effects:

[0068] In an exemplary embodiment, a conveying device includes at least two transfer members 1, a driving member 2, a sensing member 3 and a control member.

[0069] The transfer members 1 are arranged in sequence along the first direction 7 , and transfer the materials thereon in sequence along the first direction 7 .

[0070] The number of the driving members 2 is the same as the number of the transfer members 1 and corresponds to each other, so as to control the transfer speed of each transfer member 1, so that the transfer speed of each transfer member 1 is independent.

[0071] There are several groups of sensing elements 3, and they are used to sense whether there is material on each transfer element 1;

[0072] The control member is suitable for controlling the previous driving member 2 to increase the transfer speed of the previous transfer member 1 when a sensing member 3 senses that there is no material on the corresponding transfer member 1, thereby increasing the transfer speed, and ensuring that the distance between materials meets the requirements through the differential coordination of multiple transfer members 1, thereby preventing the distance between materials from being too large, ensuring the production rhythm of the next workstation, and thus speeding up work efficiency. And the sensing member 3 obtains whether there is material on the transfer member 1 by sensing, without a lot of analysis, which is simpler.

[0073] In an exemplary embodiment, the control component is suitable for controlling the previous driving component 2 to reduce the transfer speed of the previous transfer component 1 when a sensing component 3 senses that there is material on the corresponding transfer component 1, and ensures that the distance between materials meets the requirements through the differential coordination of multiple sections of transfer components 1, thereby preventing the distance between materials from being too small, resulting in material accumulation or collision, and affecting the production rhythm of the next workstation.

[0074] In an exemplary embodiment, the control component sequentially obtains the sensing information of the sensing components 3 in the opposite direction of the first direction 7, and controls the state of the driving component 2 according to the sensing information of each sensing component 3, so that the sensing component 3 on the side close to the next workstation is activated first, which can speed up work efficiency.

[0075] In an exemplary embodiment, the control member is also suitable for obtaining the amount of material within the first spacing 33, and controlling each driving member 2 when the amount of material within the first spacing 33 is equal to a threshold value, so as to adjust the transfer speed of each of the transfer members 1, and adjust the transfer speed of each transfer member 1 to increase or decrease according to the working state of the next station. If the next station is working, the transfer speed of all or part of the transfer members 1 is reduced to prevent collision. If the next station is in a state of waiting for incoming materials, the transfer speed of all or part of the transfer members 1 is accelerated to speed up the beat, so as to prevent the harm caused by further accumulation of materials when the materials are about to accumulate. Of course, the adjustment can also be carried out according to the above method, that is, when there is no material on the transfer member 1, the transfer speed of the previous transfer member 1 is increased, and when there is material on the transfer member 1, the transfer speed of the previous transfer member 1 is reduced, so that the amount of material within the first spacing 33 is equal to the threshold value to reduce material accumulation.

[0076] In an exemplary embodiment, the sensing element 3 includes a first counting element and a second counting element, and the spacing between the first counting element and the second counting element is a first spacing 33. The size of a single material is obtained and a threshold is obtained based on the size of the single material and the first spacing 33. The threshold is obtained by using the original sensing element 3 (that is, the sensing element 3 used to measure whether there is material on the transfer element 1, and some sensing elements 3 are also used as conditions for obtaining the threshold), which is simple and convenient. The number of materials within the first spacing 33 is obtained by calculating the difference between the number of materials passing through the first counting element and the second counting element. The number of materials within the first spacing 33 is obtained by using the original sensing element 3, which is simple and convenient, with a small amount of calculation and is relatively simple.

[0077] In an exemplary embodiment, the output member is suitable for outputting materials to the frontmost transfer member 1 along a first direction 7, and the control member is suitable for controlling the output member to stop when the amount of materials within the first spacing 33 is equal to a threshold value and the sensing member 3 senses that there is material on the frontmost transfer member 1, thereby preventing the output member from continuing to output and causing serious accumulation of materials. In some embodiments, the output member also has a relatively large output speed. By stopping the output member, materials with relatively large kinetic energy are prevented from colliding with materials on the frontmost transfer member 1 when being output to the frontmost transfer member 1, causing the risk of collision with the machine.

[0078] In an exemplary embodiment, each transfer member 1 is tilted downward along the same side perpendicular to the first direction 7, so that the materials are located on the same side, which is convenient for subsequent workstation actions.

[0079] In an exemplary embodiment, the transfer member 1 on the rearmost side is suitable for conveying materials to the transfer member 4, the pushing member 6 is suitable for pushing the materials on the transfer member 4 to the conveying member 5 along the second direction 8, and the conveying member 5 is suitable for transferring the materials thereon along the second direction 8, thereby facilitating the transfer of materials from the transfer member 1 and preventing material accumulation on the transfer member 1.

[0080] In an exemplary embodiment, the sensing member 3 on the rear side is arranged close to the transfer member 4, and the control member is suitable for calculating the number of materials passing through the sensing member 3 on the rear side, and when the number of materials passing through the sensing member 3 on the rear side reaches the single pushing number, the pushing member 6 is controlled to push the materials, so that the pushing member 6 can push multiple materials at the same time, thereby reducing the working frequency of the pushing member 6 and increasing work efficiency.

[0081] In an exemplary embodiment, the single push quantity is obtained according to the size of a single material and the size of the transfer member 4, or the single push quantity is obtained according to the size of a single material and the size of the pushing member 6, which is simple and convenient.

[0082] In an exemplary embodiment, a conveying device includes at least two transfer members 1, a driving member 2, a sensing member 3 and a control member. Each transfer member 1 is arranged in sequence along a first direction 7, and transfers the material thereon in sequence along the first direction 7. The number of driving members 2 is the same as the number of transfer members 1, and corresponds one to one to control the transfer speed of each transfer member 1, so that the transfer speed of each transfer member 1 is independent. The sensing member 3 is used to sense whether there is material on each transfer member 1; the control member is suitable for controlling the previous driving member 2 when a sensing member 3 senses that there is material on the corresponding transfer member 1, so as to reduce the transfer speed of the previous transfer member 1, and ensure that the distance between materials meets the requirements through the differential coordination of multiple sections of transfer members 1, thereby preventing the spacing between materials from being too small, resulting in material accumulation or collision, affecting the production rhythm of the next workstation, and thus speeding up work efficiency.

[0083] In an exemplary embodiment, a control method of a transfer member 1 senses whether there is material on a transfer member 1. When there is no material on the transfer member 1, the transfer speed of the previous transfer member 1 is increased; when there is material on the transfer member 1, the transfer speed of the previous transfer member 1 is reduced. The differential speed coordination of multiple transfer members 1 ensures that the distance between materials meets the requirements, ensures the production rhythm of the next workstation, and thus speeds up work efficiency. In addition, the sensing method is used to obtain whether there is material on the transfer member 1, which does not require a lot of analysis and is simpler.

Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
