Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment, and in particular relates to a water meter unloading line with an inclined non-powered roller. Background Art

[0002] In the water meter production process, a non-powered roller unloading line is often used to carry out the flow process of water meters between various workstations.

[0003] The unpowered roller unloading line is suitable for conveying items with a flat bottom, and is mainly composed of a transmission roller, a rack, a bracket, etc. It has the characteristics of large conveying capacity and high speed, and can realize the characteristics of multi-variety co-linear diversion conveying.

[0004] However, on the traditional unpowered roller unloading line with an inclination, the material box equipped with the water meter rolls down the line directly through the inclined roller. The terminal speed is relatively fast, which will have a greater impact on the baffle at the end of the unloading line. The impact will cause the water meter in the material box to collide and cause damage to the water meter. Instead of using a baffle at the end, the method of connecting a deceleration slide at the end of the unloading line will be limited by the site. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a water meter unloading line with an inclined unpowered roller to solve the problem that the baffle of the existing unpowered roller unloading line with an inclined roller may cause the water meter inside the material box to collide and cause damage to the water meter, and the use of a deceleration slide may be subject to site restrictions.

The fixed end of the speed reduction mechanism is fixedly connected to at least one cross bar, and the telescopic end of the speed reduction mechanism points to the roller above the speed reduction mechanism.

[0033] 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.

[0034] Embodiment 1:

[0035] like Figure 1 As shown, a water meter unpowered drum feed line with an inclination includes:

[0036] Unpowered roller unloading line; the material box is placed on the unpowered roller unloading line, the unpowered roller unloading line is tilted, the end of the unpowered roller unloading line at a lower position is the first end, and the end at a higher position is the second end;

[0037] Three intercepting mechanisms with sensing devices; the intercepting mechanisms are fixedly installed on the bottom surface of the unpowered roller unloading line in sequence along the moving direction of the material box. The intercepting mechanisms are used to intercept or release the material box above them. The intercepting mechanism closest to the first end always maintains an intercepting state. In the initial state, all intercepting mechanisms are in an intercepting state. The sensing device is used to sense whether there is a material box on the intercepting mechanism where it is located and generate a sensing signal;

[0038] A control module for collecting sensing signals and controlling the state transition of an interception mechanism; the control module is connected to the interception mechanism, and when the sensing device senses that there is a material box on one interception mechanism, while there is no material box on the adjacent interception mechanism close to the first end, the control module controls the interception mechanism with the material box to transition from an interception state to a release state; when the sensing device senses that there is no material box on one interception mechanism, the control module controls the interception mechanism without the material box to transition from a release state to an interception state. The control module adopts Siemens s7-1214 model PLC, and the solenoid valve on the interception mechanism is controlled by the PLC output point.

[0039] In this embodiment, the present application controls the interception mechanism of the three-belt sensing device through the control module to switch between the interception state and the release state, thereby realizing the stop-type and progressive unloading of the material box. The material box will be intercepted every time it slides a certain distance, thereby realizing that the material box speed is reset to zero multiple times during the unloading process, avoiding the water meter being damaged by excessive terminal speed when directly using the sloped unpowered roller unloading line, and the present application does not need to install a deceleration slide at the end of the unloading line, reducing site dependence.

[0040] Embodiment 2:

[0041] The difference between this embodiment and embodiment 1 is that Figure 1 , Figure 2 and Figure 4 As shown, the unpowered roller unloading line includes:

[0042] Two parallel crossbars 1;

[0043] Multiple rollers 2; one end of each roller 2 is rotatably connected to the side of a cross bar 1, and the other end of each roller 2 is rotatably connected to the side of another cross bar 1, the rotation axis of the roller 2 is perpendicular to the cross bar 1, a gap is provided between two adjacent rollers 2, and a material box is placed on the roller 2.

[0044] Embodiment 3:

[0045] The difference between this embodiment and embodiment 2 is that Figure 1 , Figure 2 and Figure 3 As shown, the interception mechanism includes:

[0046] A first mounting bracket 3; both ends of the first mounting bracket 3 are fixedly mounted on the bottom surfaces of the two cross bars 1;

[0047] The first lifting cylinder 9 is connected to the control module, the cylinder body of the first lifting cylinder 9 is fixedly mounted on the first mounting bracket 3, the cylinder body of the first lifting cylinder 9 is located below the drum 2, and the lifting end of the first lifting cylinder 9 is vertically directed to the gap between the two drums 2 above the first lifting cylinder 9;

[0048] Lifting baffle 4; the lifting baffle 4 is fixedly mounted on the telescopic end of the first lifting cylinder 9. When in the intercepting state, the lifting baffle 4 passes through the gap between the two rollers 2 above the first lifting cylinder 9 and is in extrusion contact with the side of the material box.

[0049] In this embodiment, when the control module controls the telescopic end of the first lifting cylinder 9 to rise, the telescopic end of the first lifting cylinder 9 drives the lifting baffle 4 to rise, and the lifting baffle 4 passes through the gap between the two rollers 2 above the first lifting cylinder 9 and is squeezed into contact with the side of the material box to intercept the material box. When the control module controls the telescopic end of the first lifting cylinder 9 to descend, the lifting baffle 4 falls back from the gap between the two rollers 2 above the first lifting cylinder 9, releases the contact with the material box, and releases the material box.

[0050] Embodiment 4:

[0051] The difference between this embodiment and embodiment 3 is that Figure 1 , Figure 4 and Figure 5As shown, the unpowered roller water meter unloading line with an inclination also includes a plurality of speed reduction mechanisms, which are connected to the control module, and are arranged below the roller 2. One speed reduction mechanism is arranged between two interception mechanisms, and the speed reduction mechanism includes a fixed end and a telescopic end. The fixed end of the speed reduction mechanism is fixedly connected to the two cross bars 1, and the telescopic end of the speed reduction mechanism points to the roller 2 located above the speed reduction mechanism. When the interception mechanism adjacent to the speed reduction mechanism and close to the first end of the unpowered roller unloading line is in a release state, the telescopic end of the speed reduction mechanism is in a contracted state. When the interception mechanism adjacent to the speed reduction mechanism and close to the first end of the unpowered roller unloading line is in an interception state, the telescopic end of the speed reduction mechanism rises and is squeezed and contacted with the roller 2 above the speed reduction mechanism.

[0052] In this embodiment, the deceleration mechanism is used to convert the rolling friction between the material box and the roller 2 into sliding friction by limiting the rotation of the part of the roller 2 above the intercepting mechanism, thereby realizing the prior deceleration of the material box and preventing the material box from impacting the intercepting mechanism when the distance between the two intercepting mechanisms is too long, thereby causing the water meter in the material box to be damaged by collision.

[0053] Embodiment 5:

[0054] The difference between this embodiment and embodiment 4 is that Figure 1 , Figure 4 and Figure 5 As shown, the reduction mechanism includes:

[0056] The second lifting cylinder 8 is connected to the control module, the cylinder body of the second lifting cylinder 8 is fixedly mounted on the second mounting bracket 7, the cylinder body of the second lifting cylinder 8 is located below the drum 2, and the lifting end of the second lifting cylinder 8 is vertically pointed in the direction of the drum 2;

[0057] The deceleration baffle 6 is fixedly mounted on the telescopic end of the second lifting cylinder 8. When the interception mechanism is in the interception state, the deceleration baffle 6 is in extrusion contact with the drum 2.

[0058] In this embodiment, when the control module controls the telescopic end of the second lifting cylinder 8 to rise, the telescopic end of the second lifting cylinder 8 drives the deceleration baffle 6 to rise, and the deceleration baffle 6 is in squeeze contact with the roller 2 above the second lifting cylinder 8, thereby converting the rolling friction between the material box and the roller 2 into sliding friction, thereby realizing the prior deceleration of the roller 2. When the control module controls the telescopic end of the second lifting cylinder 8 to descend, the deceleration baffle 6 is released from the squeeze contact with the roller 2.

[0059] Embodiment 6:

[0060] The difference between this embodiment and embodiment 3 is that Figure 1As shown, the sensing device is a photoelectric sensor 5, which is fixedly mounted on the cross bar 1. The sensing end of the sensing device of an intercepting mechanism points to the gap near the second end of the unpowered roller unloading line, which is adjacent to the gap indicated by the lifting end of the first lifting cylinder 9 of the intercepting mechanism.

[0061] In this embodiment, the photoelectric sensor 5 can generate different sensing signals through changes in light. When there is a material box in the gap, the light becomes darker, and the sensing signal is "there is a material box". When there is no material box in the gap, the light becomes brighter, and the sensing signal is "there is no material box".
