Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and in particular relates to an automatic sorting mechanism and a feeding machine with the same. Background Art

[0002] At present, the manufacturing industry has higher and higher requirements for automation. Taking the field of laser pipe cutting as an example, it is necessary to equip the automatic pipe feeder to assist the pipe cutting machine for cutting to improve efficiency and the success rate of feeding. Therefore, the feeder can realize automatic feeding and has high requirements for feeding efficiency and material distribution success rate. There are various types of feeders on the market, but generally there are the following problems: 1. The material blocking mechanism and the material distribution mechanism are independent of each other. The large number of mechanisms leads to a complex structure, many actions and low efficiency; 2. The push-back mechanism returns to the position of a fixed space to accommodate a pipe each time. When the pipe crosses or tilts, it cannot ensure that the pipe above the slope slides back to its position normally; 3. When the pipe is divided, the pipe slides down by gravity. When the surface of the pipe is rough and the friction is large, the risk of the pipe not sliding down increases. Therefore, it is necessary to propose a feeder with high material distribution efficiency and high material distribution success rate. Utility Model Content

[0034] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0035] The utility model provides an automatic sorting mechanism 1 and a feeding machine having the same, such as Figure 1 As shown, multiple automatic sorting mechanisms 1 are arranged side by side and then cooperated with a material pulling belt mechanism 3 to form a feeding machine. The bottom of the material pulling belt mechanism 3 stores the pipes 2 to be fed. The material pulling belt mechanism 3 pulls the pipes 2 upward to the top surface of the automatic sorting mechanism 1, and then the pipes 2 slide backward to the next station to achieve feeding. It should be noted that the material pulling belt mechanism 3 is an existing conventional device, which transports the pipes 2 from bottom to top to the automatic sorting mechanism 1.

[0036] For ease of description, in the present invention, the path along which the pipe 2 moves from the material pulling belt mechanism 3 from bottom to top to the automatic sorting mechanism 1 is the loading path, and the path along which the pipe 2 slides down on the automatic sorting mechanism 1 to the next station is the feeding path. In the following description, "inside" and "back" refer to the direction in which the automatic sorting mechanism 1 is away from the material pulling belt mechanism 3, and "outside" and "front" refer to the direction in which the automatic sorting mechanism 1 is close to the material pulling belt.

[0037] In the present invention, the automatic sorting mechanism 1 includes a feeding rack 101, a lifting assembly, a first pushing assembly and a second pushing assembly. The first pushing assembly is slidably arranged on the side of the feeding rack 101. The lifting assembly and the second pushing assembly are both arranged on the first pushing assembly, and the lifting assembly is connected to the second pushing assembly. The technical solution of the present invention is described in detail with a specific structure.

[0038] like Figure 1-8 As shown, the top surface of the feeding rack 101 is an inclined surface, which facilitates the pipe 2 to slide or roll backward on the top surface of the feeding rack 101 to realize the feeding of subsequent processes, which is the feeding path.

[0039] A first guide rail 106 is arranged on the side of the feed rack 101. The first guide rail 106 is parallel to the top surface of the feed rack 101, i.e., the feeding path. The outer end of the first guide rail 106 is close to the edge of the feed rack 101, i.e., close to the pulling belt mechanism 3. The function of the first guide rail 106 is to be connected with the first pushing assembly to realize the movement of the first pushing assembly on the feed rack 101.

[0040] The number of the first guide rails 106 is at least two, and the plurality of first guide rails 106 are arranged in parallel.

[0041] The top surface of the feed rack 101, close to one end of the pulling belt, forms a temporary storage space for temporarily storing the pipe 2 under the cooperation of the jacking assembly and the first pushing assembly. A roller assembly 115 is also arranged on the top surface of the feed rack 101. The roller assembly 115 is located at the outer end of the top surface of the feed rack 101. Preferably, the roller assembly 115 is a double-row roller mechanism. The double-row roller mechanism is located in the temporary storage space to provide an initial sliding speed for the rough pipe 2, eliminate static friction, and prevent the pipe 2 from sliding on the top surface of the feed rack 101.

[0042] like Figure 2-5 As shown, the first pusher assembly includes a mounting plate 102, a driving plate 103, a gear 105 and a motor. The mounting plate 102 is located outside the side of the feed rack 101. The mounting plate 102 is provided with a first slider 116 adapted to the first guide rail 106. The mounting plate 102 is slidably connected to the first guide rail 106 through the first slider 116. The driving plate 103 is fixedly arranged on the inner side of the mounting plate 102. A rack 104 is arranged on the edge of the driving plate 103. The rack 104 is parallel to the first guide rail 106. The gear 105 is meshed with the rack 104. The motor is fixedly arranged on a side of the feed rack 101 away from the mounting plate 102, and the transmission shaft of the motor passes through the feed rack 101 and is connected to the gear 105.

[0043] It is easy to understand that the rotation of the gear 105 causes the mounting plate 102 to move along the first guide rail 106. The lifting assembly and the second pushing assembly are both on the mounting plate 102 and move with the mounting plate 102. The first pushing assembly is movable on the side of the feeding rack 101, which is convenient for adjusting the size of the temporary storage space and is suitable for pipes 2 of different sizes.

[0044] Furthermore, the length of the rack 104 on the driving plate 103 is greater than or equal to the length of the first guide rail 106. Figure 3-4 As shown, the gear 105 is located outside the inner end of the first guide rail 106 , and the gear 105 is close to the first guide rail 106 , that is, the distance that the gear 105 drives the mounting plate 102 to move is greater than or equal to the length of the first guide rail 106 .

[0045] When the mounting plate 102 moves to the limit position in the direction of the material pulling belt, the lifting assembly and the second material pushing assembly are at the edge of the top of the feeding rack 101. At this time, the temporary storage space is the smallest and cannot accommodate the pipe 2.

[0046] Furthermore, the feeding frame 101 is provided with a first proximity sensor 107 for detecting the outer limit position and a second proximity sensor 108 for detecting the inner limit position, and the bottom surface of the mounting plate 102 is also provided with a detection sheet for the first proximity sensor 107 and the second proximity sensor 108 to cooperate with. The first proximity sensor 107 is close to the material drawing belt mechanism 3 and corresponds to one end of the first guide rail 106, and the second proximity sensor 108 is far away from the material drawing belt mechanism 3 and corresponds to the other end of the first guide rail 106. It is easy to understand that the first proximity sensor 107 and the second proximity sensor 108 detect the position of the mounting plate 102. When the mounting plate 102 moves outward to the extreme position, the first proximity sensor 107 detects the existence of the mounting plate 102, preventing the mounting plate 102 from continuing to move outward, causing the gear 105 to separate from the rack 104. At this time, the temporary storage space is the smallest and cannot accommodate the pipe 2. When the mounting plate 102 moves inward to the extreme position, the second proximity sensor 108 detects the position of the mounting plate 102, preventing the mounting plate 102 from continuing to move inward, causing the mounting plate 102 to contact the gear 105. At this time, the temporary storage space is the largest.

[0047] like Figure 2-5 As shown, the lifting assembly includes a lifting mechanism and a baffle 110 . The lifting mechanism is disposed on the mounting plate 102 . The baffle 110 is connected to the top of the lifting mechanism. The movement path of the baffle 110 is perpendicular to the first guide rail 106 .

[0048] Preferably, the length of the baffle 110 is greater than or equal to twice the diameter of the tube 2. When the pulling belt mechanism 3 is feeding the tube 2, two tubes 2 may be simultaneously conveyed to the top surface of the feeding rack 101. The length of the baffle 110 of the utility model is adapted to the situation of two tubes 2, preventing the tube 2 at a high position from passing over the baffle 110 and falling directly to the rear of the lifting mechanism.

[0049] In the present invention, the structure of the lifting mechanism can be various, as long as it is a suitable structure that can realize the lifting and lowering of the baffle 110. Preferably, the present invention proposes one feasible lifting mechanism structure as follows:

[0050] The lifting mechanism includes a first cylinder 109 and a mounting seat. The baffle 110 and the mounting seat are distributed from top to bottom on a side of the mounting plate 102 away from the feed rack 101. The mounting seat is fixedly connected to the mounting plate 102. A second guide rail is set on the side of the baffle 110 facing the mounting plate 102. The direction of the second guide rail is perpendicular to the direction of the first guide rail 106. The mounting plate 102 is provided with a second slider 114 that cooperates with the second guide rail. The second guide rail of the baffle 110 is slidably connected to the second slider 114 of the mounting plate 102. The cylinder body of the first cylinder 109 is fixedly set on the mounting seat, and the piston rod of the first cylinder 109 is connected to the baffle 110 through a connecting piece 111. The second pushing assembly is set at the top of the baffle 110.

[0051] It is easy to understand that the first cylinder 109 controls the lifting and lowering of the baffle 110. When the first cylinder 109 drives the baffle 110 to rise and fall to the extreme position, it is in a state of blocking the pipe 2. When the first cylinder 109 drives the baffle 110 to drop to the extreme position, the pipe 2 can slide backward along the top surface of the feeding rack 101.

[0052] The second pusher assembly includes a push mechanism and a push plate 113 . The push mechanism is disposed at the top of the baffle 110 . The push plate 113 is connected to the push mechanism. The movement path of the push plate 113 is parallel to the first guide rail 106 .

[0053] It is easy to understand that the function of the second pushing assembly is to push the excess pipe 2 back into the pulling belt mechanism 3.

[0054] In the present invention, the structure of the pushing mechanism can be various, as long as it is a suitable structure that can realize the extension and retraction of the push plate 113. Preferably, the present invention proposes one feasible pushing mechanism structure as follows:

[0055] like Figure 2-5 As shown, the pushing mechanism is the second cylinder 112, the cylinder body of the second cylinder 112 is fixedly arranged on the baffle 110, parallel to the first guide slide rail 106, and the push plate 113 is connected to the piston rod of the second cylinder 112. When the push plate 113 is in a fully retracted state, the push plate 113 is completely in the baffle 110. When the push plate 113 is in a fully extended state, the distance between the push plate 113 and the feeding rack 101 is greater than the diameter of the pipe 2 and less than 2 times the diameter of the pipe 2. Preferably, when the push plate 113 is in an extended state, the distance between the push plate 113 and the feeding rack 101 is greater than the diameter of the pipe 2 and less than 1.5 times the diameter of the pipe 2.

[0056] It is easy to understand that when the push plate 113 needs to be extended, the baffle 110 is in a state of being pushed upward. The pipe 2 is blocked in the temporary storage space. When there are two pipes 2 in the temporary storage space, the second cylinder 112 drives the push plate 113 to extend, push the pipe 2 on the upper side back onto the pulling belt, and then the push plate 113 is retracted and reset. At this time, there is only one pipe 2 in the temporary storage space.

[0057] like Figure 3 As shown, the side of the baffle 110 in contact with the pipe 2 is the A side, the bottom side of the push plate 113 is the C side, and the side of the push plate 113 facing the pipe 2 is the B side. When the pipe 2 enters the top side of the feeding rack 101, it first contacts the A side of the baffle 110. If there are stacked pipes 2, the pipe 2 on the upper side will contact the B side of the push plate 113. When the push plate 113 pushes the upper pipe 2 down, the C side of the push plate 113

[0058] The working process of the utility model is described below through specific implementation.

[0059] The feeder can determine the feeding status of the pipe 2 through a sensor or a camera, and the utility model does not limit the way in which the feeder monitors the feeding of the pipe 2.

[0060] There are three situations when loading the pipe 2: Example 1, there is a pipe 2 in the temporary storage space of the feeding rack 101; Example 2, there are two stacked pipes 2 in the temporary storage space of the feeding rack 101; Example 3, there are two crossed pipes 2 in the temporary storage space of the feeding rack 101 and on the pulling belt.

[0061] Embodiment 1

[0062] The first pushing assembly moves so that the temporary storage space formed by extending the baffle 110 can only accommodate one pipe 2 in length.

[0063] The pulling belt mechanism 3 transports the pipe 2 from bottom to top to the top surface of the feeding rack 101, and at this time, the baffle 110 rises to block the pipe 2 in the temporary storage space. Figure 1 As shown, when it is determined that only the same pipe 2 is in multiple automatic sorting mechanisms 1, it means that the pipe 2 is normally loaded, and the baffle 110 descends, causing the pipe 2 to slide backward along the top surface of the feeding rack 101.

[0064] Embodiment 2

[0065] The first pushing assembly moves so that the temporary storage space formed by extending the baffle 110 can only accommodate one pipe 2 in length.

[0066] The pulling belt mechanism 3 transports the pipe 2 from bottom to top to the top surface of the feeding rack 101, and at this time, the baffle 110 rises to block the pipe 2 in the temporary storage space. Figure 3-4 As shown, when it is determined that two pipes 2 are stacked in multiple automatic sorting mechanisms 1, it means that the loading of the pipes 2 is abnormal, and the pipes 2 on the top need to be pushed down.

[0067] The push plate 113 extends to push the pipe 2 on the top back to the bottom of the pull belt mechanism 3. When it is determined that only the same pipe 2 is in multiple automatic sorting mechanisms 1, the baffle 110 descends to make the pipe 2 slide backward along the top surface of the feeding rack 101.

[0068] Embodiment 3

[0069] The first pushing assembly moves so that the temporary storage space formed by extending the baffle 110 can only accommodate one pipe 2 in length.

[0070] The pulling belt mechanism 3 transports the pipe 2 from bottom to top to the top surface of the feeding rack 101. In this process, the pipes 2 may cross each other. Alternatively, when the push plate 113 pushes the upper pipe 2 of the overlapping pipes 2 back to its original position, the pipes 2 may cross each other due to the rigidity of the pipes 2. Figure 6-8 At this time, the first push assembly moves outward until the baffle 110 is close to the front end of the top surface of the feeding rack 101, pushing all the pipes 2 in the temporary storage space to the bottom of the pulling belt mechanism 3, and then the automatic sorting mechanism 1 is reset, and the pulling belt mechanism 3 is reloaded.

[0071] In the present utility model, the feeder also includes a material blocking mechanism 4, such as Figure 1 As shown, the material blocking mechanism 4 is located behind the automatic sorting mechanism 1, and includes a third cylinder 41 and a material blocking member 42. The cylinder body of the third cylinder 41 is fixedly connected to the feeding rack 101 of the automatic sorting mechanism 1, and the material blocking member 42 is connected to the piston rod of the third cylinder 41. When the material blocking member 42 is lowered to the limit position, the material blocking member 42 is lower than the top surface of the feeding rack 101.

[0072] The function of the blocking mechanism 4 is to block the pipe 2 sliding backward along the top surface of the feeding rack 101, forming a station waiting for feeding. It is easy to understand that after passing through the automatic sorting mechanism 1, the pipe 2 slides backward to the blocking mechanism 4 and is blocked, waiting for feeding. At the same time, the pipe 2 behind continues to be fed to the automatic sorting mechanism 1, waiting to slide backward. The blocking mechanism 4 is conducive to adjusting the feeding rhythm.

[0073] The embodiments provided by the utility model are described in detail above. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
