Description

Technical Field

[0001] The invention mainly relates to the technical field related to rail transportation, and in particular to a curve correction device. Background Art

[0002] At present, in the arc curve track transportation technology, the known curve correction devices are all composed of multiple sets of mechanical limiters through continuous and uninterrupted correction and shaping.

[0003] However, there are many problems with continuous and uninterrupted correction: 1. A sufficiently long space is required for slow correction, which is difficult to implement in places with limited space; 2. The travel trajectory is corrected through mechanical limiters, and there must be a certain amount of friction between the product (material) being corrected and the correction track (limiter), which greatly increases the specifications and weight restrictions of the product (material) being corrected. For products with large specifications and heavy weights, the relative friction makes it difficult to move, reducing the correction effect; 3. The efficiency is slow, the correction effect is not direct, and it takes a certain amount of time to correct slowly. Summary of the invention

[0004] In order to solve the shortcomings of the current technology, the present invention combines the existing technology and provides a curve correction device based on practical application. The device is used to correct the deviation of materials when the track for conveying materials turns. It has a simple structure, good correction effect and strong versatility.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] A curve correction device is used to correct the deviation of a pallet on which materials are placed when it flows on a curved curve track, comprising:

[0007] A first limiting guide wheel is arranged at the head end of the curve and is used to limit the position of the pallet when it flows into the curve;

[0008] The first guiding cylinder is arranged between the first end and the last end of the curve and is used to limit the position of the pallet when it flows in the curve;

[0009] The blocking cylinder and the first limiting plate are arranged at the tail end of the curve, and the two cooperate to limit the position of the tray when it flows out of the curve.

[0010] Furthermore, the first limiting guide wheel is arranged on the outer ring side of the track to limit the distance between the rear end of the tray and the edge of the track.

[0011] Furthermore, the first guide air cylinders are provided in two corresponding to each other, and the two first guide air cylinders are respectively placed on the inner ring side and the outer ring side of the track.

[0012] Furthermore, the blocking cylinder is arranged on the inner ring side of the track, the first limiting plate is arranged on the outer ring side of the track, and the blocking cylinder is located behind the first limiting plate.

[0013] Furthermore, the deviation correction device further comprises:

[0014] The first position sensor is arranged corresponding to the first guide cylinder and is used for detecting the position of the tray.

[0015] Furthermore, the deviation correction device further comprises:

[0016] The second guide air cylinder is arranged at the tail end of the curve. The second guide air cylinders are arranged in two corresponding to each other. The two second guide air cylinders are respectively placed on the inner ring side and the outer ring side of the track, so that the pallet is located in the middle of the track without contacting the edge when flowing out of the curve.

[0017] Furthermore, the second guiding cylinder is arranged behind the first limiting plate and in front of the blocking cylinder.

[0018] Furthermore, the deviation correction device further comprises:

[0019] The second position sensor is arranged corresponding to the second guide cylinder and is used for detecting the position of the tray.

[0020] Furthermore, the deviation correction device further comprises:

[0022] Furthermore, the deviation correction device further comprises:

[0023] The second limiting plate is arranged in front of the curve and is used to limit the position of the tray before it flows into the curve.

[0024] Beneficial effects of the present invention:

[0025] 1. Compared with the traditional method of continuous and uninterrupted correction through multiple sets of mechanical limiters, the present invention can quickly correct the pallets circulating on the track by reasonably arranging the limiters on the track, and the correction effect can reach nearly 100%.

[0026] 2. The present invention can correct a wide range of material specifications (weights), can reduce the problem of being unable to be corrected due to the influence of the material's own weight, and increases the number of materials placed on a single pallet.

[0027] 3. The correction device of the present invention has strong compatibility. The correction device is compatible with various types of pallets (mainly in terms of length). There is no need to manually adjust the sensor or the position of the guide cylinder during the whole process, which improves the versatility and reduces the difficulty of manual debugging.

[0033] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0034] like Figure 1-5 As shown, a curve correction device provided by an embodiment of the present invention is shown. In this embodiment, as shown in the figure, the track is driven by a transmission belt, and the curve on the track is designed to be 180° in arc.

[0035] The correction device of this embodiment mainly includes a first limiting guide wheel 2, a first guide cylinder 7, a blocking cylinder 8 and a first limiting plate 9; each part is respectively arranged at the beginning, inside and end of the curve as shown in the figure, for realizing the limiting of the pallet when it flows into the curve, inside and out of the curve, to ensure that the pallet can pass through the curve smoothly and quickly.

[0036] Specifically, in this embodiment, the first limiting guide wheel 2 is a rotatable guide wheel, which is installed at the outer ring of the track and can limit the distance between the rear end of the pallet and the edge of the track when the pallet flows into the curve, thereby avoiding friction interference and allowing the pallet to flow smoothly into the curve; at the same time, the design of the first limiting guide wheel 2 can also avoid collision when the pallet flows to the position of the first guide cylinder 7. Preferably, a second limiting plate 1 is set on the track in front of the curve, and the second limiting plate 1 allows the corrected material to be close to the position, so that it flows into the curve in a specified direction, avoiding position interference in subsequent flow.

[0037] After the pallet flows into the curve, it is forced to correct when it moves to the position of the first guide cylinder 7. The first guide cylinder 7 is preferably set at the middle position close to the curve. The position of the pallet forced to correct is detected by the first position sensor 3 set corresponding to the first guide cylinder 7. When the pallet is forced to correct, the conveyor belt stops rotating to ensure that the force applied by the first guide cylinder 7 to the pallet is an effective force to avoid erroneous displacement. There are two first guide cylinders 7, which are respectively located at the inner ring and the outer ring of the track. The cylinder rod of the first guide cylinder 7 has a bending plate for pushing the pallet to move through the bending plate. During forced correction, the first guide cylinder 7 reciprocates 3 times, and the two first guide cylinders 7 work together to give the pallet a clockwise twist. The first guide cylinder 7 uses a DN25-125 double cylinder to ensure that the lateral thrust can reach 39 kg. Preferably, a second limiting guide wheel 4 is provided at a position corresponding to the first guiding cylinder 7. The second limiting guide wheel 4 is located at the inner ring of the guide rail. The second limiting guide wheel 4 is used for extreme limiting, and it is also a rotatable guide wheel structure. When the air source pressure of the first guiding cylinder 7 is large or the material to be corrected is too light, the thrust of the cylinder causes the material to twist clockwise, and it moves a certain distance more under the action of inertia. At this time, the second limiting guide wheel 4 limits the maximum movable distance of the pallet. The distance from the maximum position of the first guiding cylinder 7 to the edge of the second limiting guide wheel 4 is to ensure the effective position range that the pallet can enter, and within this range it can reliably enter the track of subsequent processing equipment.

[0038] After the first guiding cylinder 7 completes the guiding, the conveyor belt rotates and the pallet flows to the end of the curve. The blocking cylinder 8 at the end of the curve has two main functions: 1) When the material of the previous pallet has not been processed, it blocks the new pallet from entering the processing area behind; 2) As the pallet moves, one corner of the pallet first contacts the blocking cylinder 8, and under the push of the conveyor belt, the tail swings in the centrifugal direction and gradually approaches the first limit plate 9. At this time, the pallet position can enter the processing track under the joint action of the blocking cylinder 8 and the first limit plate 9. Preferably, a second guiding cylinder 6 is also arranged behind the first limit plate 9 and in front of the blocking cylinder 8. The second guiding cylinder 6 is two and is respectively located on the inner ring and outer ring of the track. A second position sensor 5 is arranged corresponding to the position of the second guiding cylinder 6. After the second position sensor 5 senses the pallet, the second guiding cylinder 6 acts to make the pallet located in the middle of the track without contact with the edge, thereby ensuring that the pallet enters the processing area smoothly. At the same time, the conveyor belt stops rotating 3 seconds after the second position sensor 5 gives a signal, waiting for the next instruction.

[0039] At this point, the entire curve correction process is completed.

[0040] The curve correction device provided in this embodiment can quickly correct the pallet when it is flowing in the curve, has good correction effect, covers a wide range of specifications of the corrected materials, reduces the influence of the material's own weight on the correction effect, and is compatible with various types of pallets, with strong versatility.
