Description

Technical Field

[0001] The present invention relates to the technical field of conveying machinery, in particular to a self-propelled trolley with a top capable of moving laterally and an operating method thereof. Background Art

[0002] In the logistics and conveying machinery system, when the processing equipment is in normal production, the workpiece falls into the material box through the port of the chute, so one side of the material box must be located below the chute. However, if the material box on the self-propelled trolley drops vertically directly, it will interfere with the chute in space. Therefore, at present, various companies basically use manual operations in the processes of emptying and taking out the loaded material boxes. Its main disadvantages are low efficiency and high labor intensity.

[0003] Now, some leading companies want to use self-propelled trolleys and horizontal motions to achieve unmanned operations in the processes of emptying and taking out loaded material boxes. However, since old factories are equipped with a large number of air-conditioning, compressed air, cable trays and other pipelines, this is difficult to achieve. Therefore, the height of the self-propelled trolley is greatly limited.

[0004] If the self-propelled trolley adopts multi-level rigid guide for lifting, the height space of the factory building does not allow it, so the self-propelled trolley can only adopt a flexible lifting structure. However, in the flexible lifting, the lifting frame is prone to shaking when it moves horizontally at the bottom, resulting in inaccurate positioning. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a self-propelled trolley with a top capable of moving laterally and an operating method thereof, so as to solve the problems mentioned in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a workshop 1A for producing a workpiece 1 includes a material box 2, an overhead track 3, a self-propelled trolley 4, and processing equipment 5; the self-propelled trolley 4 includes a vehicle body 4A, a traveling device 4B, a lifting device 4C, and a clamp 4D; the vehicle body 4A includes a fixed base frame 4A1, a sliding top frame 4A2, and a sliding power 4A3; the sliding top frame 4A2 moves transversely on the fixed base frame 4A1 perpendicular to the overhead track 3 through the sliding power 4A3; the traveling device 4B is installed on the fixed base frame 4A1; the lifting device 4C is installed on the fixed base frame 4A1; Device 4C includes a hoist 4C1, a flexible cable 4C2, and a lifting frame 4C3. Hoist 4C1 is mounted on a sliding top frame 4A2. The upper end of flexible cable 4C2 is fixed to hoist 4C1, and the lower end is fixed to lifting frame 4C3. A clamp 4D is mounted on lifting frame 4C3. A workpiece 1 is placed in a magazine 2, and clamp 4D can grasp the magazine 2. Fixed base frame 4A1 is able to run on an aerial track 3 via a running device 4B. The magazine 2 moves up and down with lifting frame 4C3, or moves laterally with sliding top frame 4A2. The processing equipment 5 includes a discharge port device 5A and a limit seat 6 located below the discharge port device 5A. After being processed by the processing equipment 5, the workpiece 1 falls from the discharge port device 5A into the material box 2 located in the limit seat 6. The limit seat 6 includes a seat frame 6A, a front limit 6B, and a rear limit 6C. The front limit 6B and the rear limit 6C are both mounted on the seat frame 6A. Assume that the centerlines of the sliding top frame 4A2, the fixed bottom frame 4A1, and the aerial track 3 coincide in their original positions, and that the centerline of the loaded cassette 2 on the limit seat 6 is at a distance a from the left side of the centerline of the aerial track 3. At this point, the left side of the cassette 2 or the lifting frame 4C3 hits the front limit 6B. When the right side of the cassette 2 or the lifting frame 4C3 hits the rear limit 6C, the centerline of the cassette 2 coincides with the centerline of the aerial track 3. The main operating steps for the self-propelled trolley 4 to grasp the limit seat 6 and load the cassette 2 are as follows: 1) The empty self-propelled trolley 4 runs along the aerial track 3 to a set distance, and the sliding top frame 4A2 moves to the left a distance a, so that the center line of the clamping claw 4D coincides with the center line of the load box 2 in their top view; 2) When the lifting frame 4C3 descends to the lowest position, the clamping claw 4D moves; 3) When the lifting frame 4C3 rises to the set distance, the loading box 2 is separated from the limiting seat 6, but is still below the discharge port device 5A; 4) The sliding top frame 4A2 moves to the right, and the right end of the loading box 2 hits the rear limit 6C; the lifting frame 4C3 rises to the highest position, and the sliding top frame 4A2 returns to its original position.

[0008] As a further solution of the present invention: the lifting frame 4C3 includes a high lifting frame 4C3A. When the high lifting frame 4C3A is at the lowest position, there is no spatial interference between it and the discharge port device 5A.

[0009] As a further solution of the present invention: the lifting frame 4C3 includes an H-shaped lifting frame 4C3B, and the H-shaped lifting frame 4C3B includes a notch 4C3B1; when the H-shaped lifting frame 4C3B is at the lowest position, the discharge port device 5A is located in the notch 4C3B1 of the H-shaped lifting frame 4C3B.

[0010] As a further solution of the present invention: the limit seat 6 includes a material box limit seat 61, and the material box limit seat 61 includes a material box seat frame 61A, a material box front limit 61B and a material box rear limit 61C; when the left side of the material box 2 hits the material box front limit 61B, the center line of the material box 2 is a distance a from the left side of the center line of the aerial track 3; when the right side of the material box 2 or the lifting frame 4C3 hits the rear limit 6C, the center line of the material box 2 coincides with the center line of the aerial track 3.

[0011] As a further solution of the present invention: the material box 2 includes a flange edge 2A, the clamping jaw 4D includes a telescopic clamping jaw 7, the telescopic clamping jaw 7 includes a telescopic tongue 7A and a telescopic cylinder 7B; when the telescopic tongue 7A is extended through the telescopic cylinder 7B, the telescopic clamping jaw 7 can grasp the flange edge 2A.

[0012] As a further solution of the present invention, the self-propelled trolley 4 includes a safety bracket 4E that can prevent the material box 2 from falling.

[0013] As a further solution of the present invention: the top of the lifting frame 4C3 includes a positioning pin 4C3C, and the vehicle body 4A includes a positioning hole 4A1A; when the lifting frame 4C3 is at the highest position, the positioning pin 4C3C can be inserted into the positioning hole 4A1A.

[0014] As a further solution of the present invention: the action of step 4 in claim 1 can be further decomposed into: 1) The sliding top frame 4A2 moves to the right a distance a+b; 2) When the loaded material box 2 moves to the right a distance, the right end hits the rear limit 61C of the material box; 3) The sliding top frame 4A2 moves to the left for a distance b, i.e. the sliding top frame 4A2 is reset; 4) Lifting frame 4C3 rises to the highest position.

[0015] As a further solution of the present invention: the main operating steps of placing the empty material box 2 on the self-propelled trolley 4 are as follows: 1) The empty self-propelled trolley 4 carries the empty material box 2 and runs along the aerial track 3 to a set distance; 2) Lifting frame 4C3 descends to the set distance; 3) Sliding top frame 4A2 moves to the left a distance a+b; 4) The empty material box 2 moves to the left for a distance, and its left end hits the front limit 61B of the material box; 5) Sliding top frame 4A2 moves to the right a distance b; 6) When the lifting frame 4C3 gradually descends to the lowest position, the empty material box 2 is placed on the material box limit seat 61, and the clamping claw 4D is released; 7) When the lifting frame 4C3 rises to the highest position, the sliding top frame 4A2 moves to the right a distance and then returns to its original position.

[0016] In summary, compared to the prior art, this invention innovatively incorporates a limit seat beneath the chute. When the bottom lift frame needs to translate a distance a, the top sliding frame translates a+b. When the magazine or lift frame encounters the front or rear limit, the sliding frame returns to distance b before executing subsequent operations. This limit seat ensures that, despite the flexible lifting structure, the bottom lift frame maintains accurate positioning even during translation. The main advantages of this invention are simple structure, low cost, and high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
