Description

Technical Field

[0001] The utility model relates to the field of automatic feeding, in particular to a device for separating disorderly stacked materials. Background Art

[0002] In the automated feeding industry, when conveyor belts are used for feeding, the materials at the robot's material collection point must be separated and cannot be stacked. The spacing must be large enough, otherwise interference will occur when the robot grabs the materials. The existing separation of disorderly stacked materials generally uses a double cylinder blocking or vibration solution to separate the materials and create spacing.

[0003] The main defects are: (1) The double-cylinder blocking solution is only applicable to parts with simple shapes. It is not suitable for use when the parts have grooves or holes, and its versatility is poor; (2) The vibration solution is unstable and the material may still be stacked after vibration. Utility Model Content

[0004] The purpose of the utility model is to provide a disorderly stacked material separation device to solve the problems raised in the above background technology.

[0008] The first baffle is formed with a lower layer gap for the bottom layer of the disorderly stacked materials to pass through; the first baffle is arranged to be inclined to the conveying direction of the first-stage conveyor belt to guide the excess materials into the return trough;

[0009] The second baffle is arranged to be inclined to the conveying direction of the first-stage conveyor belt; the inclination direction of the second baffle is the same as that of the first baffle; the second baffle blocks the side of the first-stage conveyor belt away from the return trough, so that the first-stage conveyor belt retains a single-row channel for a single row of materials to pass through at the edge of one side close to the return trough;

[0010] The third baffle is arranged to be inclined to the conveying direction of the first-stage conveyor belt; the inclination direction of the third baffle is opposite to the inclination direction of the second baffle, and the third baffle blocks the side of the first-stage conveyor belt close to the return trough to guide the material to the middle of the first-stage conveyor belt;

[0012] When the single-layer material passes through the first baffle and passes through the second baffle, the redundant materials arranged side by side through the single-row channel under the guidance of the inclined second baffle enter the return trough;

[0013] After passing through the second baffle, the inclined third baffle guides the single-row material passing through the single-row channel from the edge of the first-stage conveyor belt to the middle of the first-stage conveyor belt;

[0014] The conveying speed of the second conveyor belt is greater than that of the first conveyor belt so that the distance between two adjacent materials is increased after the materials conveyed by the first conveyor belt enter the second conveyor belt.

[0017] As a further embodiment of the present invention, a second sensor for detecting materials is provided at the downstream end of the second conveyor belt; after the second sensor detects the materials, the second conveyor belt stops moving until the materials detected by the third sensor are taken away and then resumes moving.

[0018] As a further embodiment of the present invention, the first-level conveyor belt is higher than the second-level conveyor belt; in the height direction, the downstream of the first-level conveyor belt and the upstream of the second-level conveyor belt overlap so that the material on the first-level conveyor belt falls onto the second-level conveyor belt; the second-level conveyor belt is higher than the third-level conveyor belt; in the height direction, the downstream of the second-level conveyor belt and the upstream of the third-level conveyor belt overlap so that the material on the second-level conveyor belt falls onto the third-level conveyor belt.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 4 As shown, a disorderly stacked material separation device 100 includes: a first-stage conveyor belt 10 for receiving disorderly stacked materials, a second-stage conveyor belt 20, a first baffle 40, a second baffle 50, a third baffle 60 and a return trough 70.

[0030] The first baffle 40, the second baffle 50 and the third baffle 60 are all arranged on the upper surface of the first-stage conveyor belt 10. The first baffle 40, the second baffle 50 and the third baffle 60 are mounted on the first-stage conveyor belt 10. Specifically, the first baffle 40, the second baffle 50 and the third baffle 60 are mounted on the frame of the first-stage conveyor belt 10 and the first baffle 40, the second baffle 50 and the third baffle 60 are located above the conveyor belt of the first-stage conveyor belt 10.

[0031] In the conveying direction of the first-stage conveyor belt 10 , the first baffle 40 , the second baffle 50 and the third baffle 60 are arranged in sequence. The return trough 70 is arranged on one side of the first-stage conveyor belt 10 .

[0032] The first baffle plate 40 is formed with a lower layer gap 41 for the bottom layer of the disorderly stacked materials to pass through. The first baffle plate 40 is arranged to be inclined to the conveying direction of the first-stage conveyor belt 10 to guide the excess materials to enter the return trough 70.

[0033] The second baffle 50 is arranged to be inclined to the conveying direction of the first conveyor belt 10. The inclination direction of the second baffle 50 is the same as the inclination direction of the first baffle 40. The second baffle 50 blocks the side of the first conveyor belt 10 away from the return trough 70, so that the first conveyor belt 10 retains a single-row channel for a single row of materials to pass through at the edge of one side close to the return trough 70.

[0034] The third baffle 60 is arranged to be inclined to the conveying direction of the first-stage conveyor belt 10. The inclination direction of the third baffle 60 is opposite to the inclination direction of the second baffle 50, and the third baffle 60 blocks the side of the first-stage conveyor belt 10 close to the return trough 70 to guide the material to the middle of the first-stage conveyor belt 10.

[0035] The second baffle 50 is inclined in the same direction as the first baffle 40, but at different angles. In the conveying direction of the first-stage conveyor belt 10, the first baffle 40 and the second baffle 50 are inclined to the left. The third baffle 60 is inclined to the right. The return trough 70 is located on the left side of the first-stage conveyor belt 10.

[0036] The material in the return trough 70 is transported back to the feeding mechanism, and the feeding mechanism again transports the material to the first-stage conveyor belt 10 .

[0037] When the disorderly stacked materials on the first-stage conveyor belt 10 pass through the first baffle 40 , only the lowest layer of materials passes through the lower layer gap 41 and is transmitted downstream, and the multi-layer materials stacked together enter the return trough 70 under the guidance of the inclined first baffle 40 .

[0038] When the single-layer material that has passed through the first baffle 40 passes through the second baffle 50 , the redundant materials that are arranged side by side through the single-row channel under the guidance of the inclined second baffle 50 enter the return trough 70 .

[0039] After passing through the second baffle 50 , the inclined third baffle 60 guides the single-row material passing through the single-row channel from the edge of the first-stage conveyor belt 10 to the middle of the first-stage conveyor belt 10 .

[0040] The conveying speed of the second conveyor belt 20 is greater than that of the first conveyor belt 10 so that the distance between two adjacent materials is increased after the materials conveyed by the first conveyor belt 10 enter the second conveyor belt 20 .

[0041] As a specific embodiment, a disorderly stacked material separation device 100 further includes: a third-stage conveyor belt 30. The conveying speed of the third-stage conveyor belt 30 is greater than the conveying speed of the second-stage conveyor belt 20 so that the distance between two adjacent materials is increased after the materials conveyed by the second-stage conveyor belt 20 enter the third-stage conveyor belt 30.

[0042] The above description is based on three-stage conveying. As an optional implementation, the number of conveyor belts is not limited to three. For example, two, four or more stages may be used.

[0043] As a preferred embodiment, a third sensor 31 for detecting materials is provided at the downstream end of the third conveyor belt 30. After the third sensor 31 detects the materials, the third conveyor belt 30 stops moving until the materials detected by the third sensor 31 are taken away and then resumes moving.

[0044] The material position detected by the third sensor 31 is the robot's material picking point. After the robot takes the material, the third-level conveyor belt 30 continues to convey the material until new material moves to the robot's material picking point again and is detected by the third sensor 31, and the third-level conveyor belt 30 stops waiting for the robot to take the material.

[0045] As a preferred embodiment, a second sensor 21 for detecting materials is provided at the downstream end of the second conveyor belt 20. After the second sensor 21 detects the materials, the second conveyor belt 20 stops moving until the materials detected by the third sensor 31 are taken away and then resumes moving.

[0046] As a specific embodiment, the first conveyor belt 10 is higher than the second conveyor belt 20. In the height direction, the downstream of the first conveyor belt 10 and the upstream of the second conveyor belt 20 overlap so that the material of the first conveyor belt 10 falls onto the second conveyor belt 20.

[0047] The second conveyor belt 20 is higher than the third conveyor belt 30. In the height direction, the downstream of the second conveyor belt 20 and the upstream of the third conveyor belt 30 overlap so that the materials of the second conveyor belt 20 fall onto the third conveyor belt 30.

[0048] As an optional embodiment, in a multi-stage conveyor belt, two adjacent conveyor belts can also be arranged vertically. Two adjacent conveyor belts can also be butt-jointed in the same height plane to directly transfer materials. As an optional embodiment, two adjacent conveyor belts can also be provided with guide slopes to transfer materials between the conveyor belts.

[0049] As a specific embodiment, a disorderly stacked material separation device 100 further includes: a frame 80. The first-stage conveyor belt 10, the second-stage conveyor belt 20 and the third-stage conveyor belt 30 are all installed on the frame 80. The return trough 70 is fixed to the frame 80. The first-stage conveyor belt 10, the second-stage conveyor belt 20 and the third-stage conveyor belt 30 are installed on the top of the frame 80. The return trough 70 is arranged on one side of the frame 80.

[0050] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0051] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
