Description

Technical Field

[0001] This utility model relates to a profile feeding machine and its system, specifically to an intelligent aluminum profile spraying and feeding machine and its system. Background Technology

[0002] Aluminum profiles need to be transported to the processing site before processing, and the tangled materials also need to be separated.

[0003] Chinese invention patent CN105775762A discloses a profile conveying device, comprising: a longitudinal profile feeding mechanism for measuring the length and width of the profiles and conveying them to a transverse conveying station; a transverse profile feeding mechanism for measuring the weight of the profiles at the transverse conveying station and conveying them to a sorting station; a profile sorting mechanism for arranging the profiles at the sorting station to facilitate the arranged profiles falling into a profile storage frame; and a control mechanism. However, this device cannot simultaneously transport, sort, and separate tangled profiles, resulting in low overall integration.

[0004] Chinese utility model patent CN217172360U discloses an automatic profile positioning and feeding device. It incorporates a blocking cylinder in the conveying equipment, using its lifting and lowering to control profile separation, and employing V-shaped material handling mechanisms on both sides to organize the profiles. However, the blocking cylinder lifting method for material separation suffers from problems such as incomplete separation and profile entanglement. Furthermore, due to the inherent structure of the V-shaped material handling mechanism and the need for coordination on both sides, it is prone to causing the profiles to be transported asynchronously on both sides.

[0013] Preferably, the second speed change device includes a second motor, a third gear, a fourth gear, a fifth gear, a second chain, and a third chain.

Six optical shafts are arranged on the support frame along the profile conveying direction. The two ends of the horizontal section are respectively fitted onto two optical shaft assemblies. The tail end of the first belt and the head end of the second belt, the tail end of the second belt and the head end of the third belt, the tail end of the third belt and the head end of the fourth belt, the tail end of the fourth belt, and the head end of the fifth belt are respectively fitted onto the same optical shaft assembly.

[0015] To achieve the second objective mentioned above, this utility model provides an intelligent material handling system for aluminum profile spraying and feeding, comprising two intelligent material handling machines for aluminum profile spraying and feeding, namely a first material handling machine and a second material handling machine, which are arranged side by side along the length of the profile.

[0016] Preferably, a first sensor is provided on the support frame of the first feeder, and the first sensor is located at the discharge end of the second belt;

[0020] The beneficial effects achieved by this utility model are as follows:

[0021] 1. The intelligent material handling machine uses a conveyor belt assembly that can transport profiles via belts. The rotation speed of the second belt is greater than that of the first belt. When the profile is transported from the first belt to the second belt, the profile accelerates on the second belt, thereby increasing the spacing between the profiles and realizing the separation of profiles while transporting them. This conveyor belt assembly has a high degree of integration and saves space.

[0022] 2. The conveyor belt assembly used in this intelligent material handling system also includes a second conveyor belt assembly. By setting a second speed change device, it is possible to achieve the effect of a single motor driving three belts to rotate. The second speed change device uses gears with different numbers of teeth, which can realize that the rotation speed of the third belt, the fourth belt, and the fifth belt increases sequentially, further realizing the simultaneous transportation and sorting of profiles.

[0023] 3. This intelligent material handling system includes two material handling machines. The two machines synchronously transport both ends of the same profile, increasing the contact points between the belt and the profile and improving transport stability. Each material handling machine is equipped with matching sensors. When one sensor detects that one end of the profile has reached its corresponding position, while the corresponding sensor detects that the other end has not, the belt on the faster-moving end stops working until both ends of the profile reach their corresponding positions, at which point they resume synchronous transport, achieving the desired material handling effect.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figure 1-5 As shown, this utility model discloses an intelligent material handling machine for aluminum profile spraying and feeding, including a frame 1 and a material handling equipment assembly 2. The top of the frame 1 is fixedly or detachably connected to the bottom of the material handling equipment assembly 2.

[0034] The material handling equipment assembly 2 includes a support frame 3, a conveyor belt assembly 4, and a speed change device. The conveyor belt assembly 4 is installed inside the support frame 3 and has the function of transporting and separating profiles. The conveyor belt assembly 4 includes multiple belts, which are staggered along the profile transport direction. The tail of one belt partially overlaps with the head of the next belt, allowing the profiles to be continuously transported on different belts. The number of speed change devices corresponds one-to-one with the number of conveyor belt assemblies 4, and they are respectively connected to the conveyor belt assemblies 4 for transmission. By setting up the speed change devices, each belt is driven, and the rotational speed of each belt increases sequentially along the profile transport direction.

[0035] In one embodiment of the conveyor belt assembly 4, the conveyor belt assembly 4 may consist of only one set, namely a first conveyor belt assembly. The first conveyor belt assembly includes a first belt 5 and a second belt 6. Both the first belt 5 and the second belt 6 include a horizontal section and two inclined sections connected end to end. The top surface height of the horizontal section of both belts is higher than the top surface height of the side wall of the support frame 3, and both ends of the horizontal section of both belts are supported by optical shaft assemblies. Specifically, the optical shaft assembly includes a first optical shaft assembly 7, a second optical shaft assembly 8, and a third optical shaft assembly 9, all of which are rotatably arranged on the support frame 3. The head of the horizontal section of the first belt 5 is fitted onto the first optical shaft assembly 7, and the tail is fitted onto the second optical shaft assembly 8. The head of the horizontal section of the second belt 6 is fitted onto the second optical shaft assembly 8, and the tail is fitted onto the third optical shaft assembly 9. The optical shaft assemblies only serve to support the belts and do not provide rotational power to the belts.

[0036] Two inclined sections of two belts are fitted with shaft assemblies that provide power to the belts. Specifically, the shaft assemblies include a first shaft assembly 10 and a second shaft assembly 11, both rotatably mounted on a support frame 3. The inclined section of the first belt 5 is fitted onto the first shaft assembly 10, and the inclined section of the second belt 6 is fitted onto the second shaft assembly 11. The first shaft assembly 10 and the second shaft assembly 11 are connected by a first speed-changing device. The first speed-changing device includes a first gear and a second gear, respectively fixedly mounted on the first shaft assembly 10 and the second shaft assembly 11, and a first motor 13 fixedly mounted on the support frame 3. The first gear has more teeth than the second gear, and the first gear and the second gear are connected by a first chain 12. The output shaft of the first motor 13 is connected to either the first shaft assembly 10 or the second shaft assembly 11. Specifically, the output shaft of the first motor 13 is fixedly fitted with a sixth gear, and either the first shaft assembly 10 or the second shaft assembly 11 is also fixedly fitted with a seventh gear. The sixth gear and the seventh gear are connected by a fourth chain.

[0037] As another embodiment of the conveyor belt group 4, the conveyor belt group 4 may include a first conveyor belt group and a second conveyor belt group. The first conveyor belt group has the same structure as in the previous embodiment. The second conveyor belt group includes three belts: a third belt 14, a fourth belt 15, and a fifth belt 16. Each of these three belts includes a horizontal section and two inclined sections connected end to end. Both ends of the horizontal section of the three belts are supported by optical axis assemblies. Specifically, the optical axis assemblies also include a fourth optical axis assembly 17, a fifth optical axis assembly 18, and a sixth optical axis assembly 19, all of which are rotatably arranged on the support frame 3. The head of the horizontal section of the third belt 14 is fitted onto the third optical axis assembly 9, and the tail is fitted onto the fourth optical axis assembly 17. The head of the horizontal section of the fourth belt 15 is fitted onto the fourth optical axis assembly 17, and the tail is fitted onto the fifth optical axis assembly 18. The head of the horizontal section of the fifth belt 16 is fitted onto the fifth optical axis assembly 18, and the tail is fitted onto the sixth optical axis assembly 19. The optical axis assemblies only serve to support the belts and do not provide rotational power to the belts. In this embodiment, the tail end of the horizontal section of the second belt 6 and the head end of the horizontal section of the third belt 14 can also be set on different optical axis assemblies, as long as the second belt 6 and the third belt 14 partially overlap.

[0038] At the bends of the two inclined sections of the three belts, a rotating shaft assembly is fitted to provide power to the belts. Specifically, the rotating shaft assembly includes a third rotating shaft assembly 20, a fourth rotating shaft assembly 21, and a fifth rotating shaft assembly 22, all rotatably mounted on the support frame 3. The bend of the inclined section of the third belt 14 is fitted onto the third rotating shaft assembly 20, the bend of the inclined section of the fourth belt 15 is fitted onto the fourth rotating shaft assembly 21, and the bend of the inclined section of the fifth belt 16 is fitted onto the fifth rotating shaft assembly 22. The third rotating shaft assembly 20, the fourth rotating shaft assembly 21, and the fifth rotating shaft assembly 22 are connected by a second speed change device. The second speed change device includes a third gear, a fourth gear, and a fifth gear, respectively fixedly fitted onto the third rotating shaft assembly 20, the fourth rotating shaft assembly 21, and the fifth rotating shaft assembly 22, and a second motor 23 fixedly mounted on the support frame 3. The number of teeth on the third gear, the fourth gear, and the fifth gear decreases sequentially along the profile transport direction. The third and fourth gears are connected by a second chain 29, and the fourth and fifth gears are connected by a third chain 30. The output shaft of the second motor 23 is connected to one of the third shaft assembly 20, the fourth shaft assembly 21, or the fifth shaft assembly 22. Specifically, the output shaft of the second motor 23 is fixedly fitted with an eighth gear, and the third shaft assembly 20, the fourth shaft assembly 21, or the fifth shaft assembly 22 is also fixedly fitted with a ninth gear. The eighth and ninth gears are connected by a fifth chain.

[0039] To improve the working stability of the belt, a pressure shaft assembly 24 can be added. The added pressure shaft assembly 24 can be set at any position on the inclined section of the belt and abuts against the belt drive to support the belt and increase the belt tension. Specifically, the pressure shaft assembly 24 is rotatably mounted on the support frame 3. The inclined section of the first belt 5 abuts against the pressure shaft assembly 24. The pressure shaft assembly 24 divides the remaining part of the belt (excluding the horizontal section) into two inclined sections with different slopes. Pressure shaft assemblies 24 can also be set at the same position on other belts, which will not be elaborated here.

[0040] When in use, the aluminum profile is placed on the belt and runs through the entire width of the feeder. As the aluminum profile is transported from the previous belt to the next belt, it will accelerate due to the increased belt speed, increasing the distance between adjacent profiles and achieving the function of separating the profiles.

[0041] Specifically, the profile is placed on the first belt 5, and the first motor 13 and the second motor 23 are started simultaneously. The first motor 13 drives the sixth gear to rotate, the sixth gear drives the seventh gear to rotate via the fourth chain, the seventh gear drives the second shaft assembly 11 to rotate, the second shaft assembly 11 drives the second gear to rotate, the second gear drives the first gear to rotate via the first chain 12, and then drives the first shaft assembly 10 to rotate. The first shaft assembly 10 and the second shaft assembly 11 drive the first belt 5 and the second belt 6 to rotate, respectively. The second motor 23 drives the eighth gear to drive, the eighth gear drives the ninth gear via the fifth chain, and then drives the fifth shaft assembly 22 to rotate, and then drives the fifth belt 16 to rotate. The fifth shaft assembly 22 also drives the fifth gear to rotate, the fifth gear drives the fourth gear to rotate via the third chain 30, the fourth gear drives the third gear to rotate via the second chain 29, the fourth gear and the third gear drive the fourth shaft assembly 21 and the third shaft assembly 20 to rotate, and then drive the fourth belt 15 and the third belt 14 to rotate, respectively. Because different belts are driven by gears with different numbers of teeth, the rotational speeds of the first belt 5, second belt 6, third belt 14, fourth belt 15, and fifth belt 16 increase sequentially. The first belt 5 propels the profile forward; upon contact with the second belt 6, the profile's speed increases instantaneously, thus increasing the spacing between the profiles on the second belt 6 and achieving simultaneous material conveying and distribution. Similarly, the profiles can be accelerated at the points of contact between other belts, achieving a multi-stage material distribution effect.

[0042] To improve the stability of transporting aluminum profiles and to achieve material handling functionality. For example... Figure 1 As shown, this utility model also discloses an intelligent material handling machine system for aluminum profile spraying and feeding, including two material handling machines as described above, namely a first material handling machine 25 and a second material handling machine 26, which are arranged side by side along the length of the profile.

[0043] The first material handling machine 25 is equipped with a first sensor 27, which can be located on the horizontal section of the first belt 5 or the second belt 6 and can sense the profiles being transported. As a preferred embodiment, the first sensor 27 is located at the end of the horizontal section of the second belt 6 (i.e., the discharge end). The second material handling machine 26 is equipped with a second sensor that works in conjunction with the first sensor 27. The second sensor is located at the orthographic projection of the first sensor 27 onto the second material handling machine 26 (i.e., the discharge end of the second belt 6 of the second material handling machine 26).

[0044] To achieve the two-stage material handling function, the first material handling machine 25 is also equipped with a third sensor 28. The third sensor 28 is located on the horizontal section of the third belt 14, the fourth belt 15, or the fifth belt 16. As a preferred embodiment, the third sensor 28 is located at the end of the fifth belt 16 (i.e., the discharge end). The second material handling machine 26 is equipped with a fourth sensor that works in conjunction with the third sensor 28. The fourth sensor is located at the orthographic projection of the third sensor 28 onto the second material handling machine 26 (i.e., the discharge end of the fifth belt 16 of the second material handling machine 26). The first sensor 27, the second sensor, the third sensor 28, and the fourth sensor can detect the positioning information of both ends of the profile. If it is detected that one end of the profile is in position while the other end is not, the motor on the in position side stops rotating until the other end of the profile is in position, and then the motor is restarted, thereby realizing the material handling function.

[0045] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
