Description

Technical Field

[0001] The utility model relates to the field of roller conveying mechanisms, and specifically relates to a roller loading and unloading device and a roller conveying system thereof. Background Art

[0002] The roller table is a mechanism used to transport materials in a continuous production line. It is usually powered by a motor that drives multiple rows of rollers to rotate continuously, using friction to move the materials forward.

[0003] At the end of the roller table, when the material needs to be transported to a workstation without a roller bar, or when the material at the workstation without a roller bar needs to be transported to the head end of the roller bar, the material crossing is generally completed by side pushing mechanisms, hanging mechanisms, fork delivery mechanisms, mechanical arms, etc., but these mechanisms have defects such as low load capacity, complex structure, low reliability, unstable mechanical structure, and large space occupation. Therefore, a roller loading and unloading device with a simple structure that does not occupy too much space and has stable material transfer is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a roller loading and unloading device and a roller conveying system thereof with a simple and compact structure and stable material transfer.

[0005] The utility model provides a roller loading and unloading device, comprising a bearing platform and a material transfer mechanism;

[0006] The bearing platform is arranged at an upstream / downstream end of the roller conveyor mechanism, a first through groove is arranged on the bearing platform, and a notch is arranged at one end of the first through groove close to the roller conveyor mechanism;

[0007] The material transfer mechanism includes a lifting mechanism arranged below the roller conveying mechanism, a first horizontal moving mechanism arranged on the output end of the lifting mechanism, and a driving rod arranged on the output end of the first horizontal moving mechanism;

[0008] The first horizontal moving mechanism is used to drive the driving rod to slide in the first through slot and move toward the upstream / downstream end of the roller conveyor mechanism through the slot, and the lifting mechanism is used to drive the upper end of the driving rod to be higher or lower than the bearing plane of the roller conveyor mechanism.

[0009] Furthermore, the bearing platform is coplanar with the bearing plane of the roller conveyor mechanism.

[0010] Furthermore, the carrying platform is made of graphite material.

[0011] Furthermore, a limit stopper is provided at one end of the carrying platform away from the roller conveying mechanism.

[0012] Furthermore, the first horizontal moving mechanism is a linear module; the lifting mechanism includes two cylinders arranged on both sides of the bottom of the linear module body.

[0013] Furthermore, the carrying platform is arranged on a movable bracket; the movable bracket can drive the carrying platform to leave or approach an upstream / downstream end of the roller conveying mechanism.

[0014] Furthermore, the bearing platform is arranged on the movable bracket through a leveling and height-adjusting mechanism.

[0015] Furthermore, a second through slot intersecting with the first through slot is provided on the carrying platform;

[0016] The mobile bracket is also provided with a loading and unloading mechanism for the loading and unloading platform, which includes a second horizontal moving mechanism and a push-pull member arranged on the output end of the second horizontal moving mechanism, and the second horizontal moving mechanism is used to drive the push-pull member to move along the second through slot.

[0017] Furthermore, at least two groups of first through grooves and material transfer mechanisms are arranged along the width direction of the roller conveyor mechanism.

[0018] The utility model also provides a roller conveying system, including a roller conveying mechanism and the above-mentioned roller loading and unloading device;

[0019] Several rollers of the roller conveying mechanism close to the roller loading and unloading device are provided with one-way overrunning devices.

[0020] The beneficial effect of the utility model is that the roller loading and unloading device provided by the utility model can also lift the upstream end of the material when the material passes through the switching platform due to the provision of a lifting mechanism to dock with the material, thereby preventing the material from getting stuck due to the height difference between the bearing planes of the roller conveying mechanism and the bearing platform, thereby improving the reliability of loading and unloading. Compared with the conventional side-pushing track loading and unloading device, it has better stability and requires a low height difference between the bearing planes of the roller conveying mechanism and the bearing platform. Moreover, the roller loading and unloading device is arranged below the roller conveying mechanism and the bearing platform, and does not occupy additional space, making the entire roller conveying system compact. Compared with other roller loading and unloading devices such as hanging mechanisms, fork-feeding mechanisms, and mechanical arms, the structure is simpler, the material transfer distance is short, and the efficiency of loading and unloading can be improved and energy consumption can be reduced. In addition, the utility model can speed up the efficiency of loading and unloading materials on the roller conveyor. Specifically, when the roller conveyor mechanism unloads materials, its conveying speed can be accelerated compared with the conventional roller conveyor mechanism. When the materials leave the roller conveyor mechanism, they slide frictionally with the load-bearing platform. The load-bearing platform is equivalent to a buffer zone at this time, which can quickly reduce the moving speed of the materials and avoid the problem of inertial sliding of the materials. When the roller conveyor mechanism loads materials, the material transfer mechanism drives the moving speed of the materials faster than the conveying speed of the roller conveyor mechanism, thereby improving the loading efficiency.

[0031] As attached Figure 1 -Attached Figure 4 As shown, the utility model also provides a roller loading and unloading device, which is used for loading or unloading the roller conveyor mechanism 3, so that the material 7 enters or leaves the roller conveyor mechanism 3, and includes a load-bearing platform 1 and a material transfer mechanism 2. When the roller conveyor mechanism 3 is loaded, the load-bearing platform 1 is used to carry the material 7 to be loaded, and the material transfer mechanism 2 is used to transfer the material 7 to be loaded on the load-bearing platform 1 to the upstream end of the roller conveyor mechanism 3. When the roller conveyor mechanism 3 is unloaded, the load-bearing platform 1 is used to carry the material 7 loaded and unloaded from the roller conveyor mechanism 3, and the material transfer mechanism 2 is used to transfer the material 7 at the downstream end of the roller conveyor mechanism 3 to the material load-bearing platform 1, so as to facilitate the material to be carried to the next station;

[0032] The carrying platform 1 is arranged at the upstream / downstream end of the roller conveyor mechanism 3. Specifically, when the roller conveyor mechanism 3 is loaded, the carrying platform 1 is arranged at the upstream end of the roller conveyor mechanism 3. Conversely, when the roller conveyor mechanism 3 is unloaded, the carrying platform 1 is arranged at the downstream end of the roller conveyor mechanism 3. The carrying platform 1 is provided with a first through groove 11, which runs through the upper and lower surfaces of the carrying platform 1, and the first through groove 11 is provided with a notch 12 at one end close to the roller conveyor mechanism 3.

[0033] The material transfer mechanism 2 includes a lifting mechanism 21 disposed below the roller conveyor mechanism 3, a first horizontal moving mechanism 22 disposed on the output end of the lifting mechanism 21, and a driving rod 23 disposed on the output end of the first horizontal moving mechanism 22;

[0034] Among them, the first horizontal moving mechanism 22 is used to drive the driving rod 23 to slide in the first through groove 11 and move toward the upstream / downstream end of the roller conveyor mechanism 3 through the slot 12, and the lifting mechanism 21 is used to drive the upper end of the driving rod 23 to be higher or lower than the bearing plane of the roller conveyor mechanism 3, wherein the bearing plane of the roller conveyor mechanism 3 refers to the plane formed by the upper ends of all rollers of the roller conveyor mechanism 3.

[0035] When unloading the roller conveyor mechanism 3, the material 7 is conveyed to the downstream end through the roller conveyor mechanism 3 and the end of the material 7 extends into the last roller rod at the downstream end for a certain distance. At this time, the first horizontal moving mechanism 22 can drive the driving rod 23 to move to the downstream end of the roller conveyor mechanism 3 and extend the material 7 to the bottom of the last roller rod part. Preferably, an interlocking hole 71 or a groove for interlocking with the driving rod 23 is provided at the bottom of the material 7, and then the lifting mechanism 21 can drive the driving rod 23 to rise and dock with the material 7. Finally, the first horizontal moving mechanism 22 is controlled to reset and the material 7 is pulled onto the carrying platform 1.

[0036] When loading the roller conveyor 3, first the material 7 is located on the carrying platform 1. At this time, the driving rod 23 is located in the first through groove 11, and is preferably located on the side of the material 7 away from the roller conveyor 3. Then, the lifting mechanism 21 drives the driving rod 23 to rise and dock with the bottom of the material 7 away from the roller conveyor 3. Then, the first horizontal moving mechanism 22 drives the driving rod 23 to move along the first through groove 11, driving the material 7 to move until it moves out of the slot 12 to the upstream end of the roller conveyor 3. At this time, most of the material 7 will enter some rollers of the roller conveyor 3. Then, the lifting mechanism 21 drives the driving rod 23 to descend, and the first horizontal moving mechanism 22 is reset. At this time, the material 7 is completely carried and transported by the roller conveyor 3 through the movement of the roller conveyor 3.

[0037] The roller loading and unloading device provided by the utility model is provided with a lifting mechanism 21 to dock with the material 7. When the material 7 passes through the switching platform, the upstream end of the material 7 can also be lifted, so that the material will not be stuck due to the height difference between the bearing planes of the roller conveyor mechanism 3 and the bearing platform 1, thereby improving the reliability of loading and unloading. Compared with the conventional side push track loading and unloading device, it has better stability and low requirements for the height difference between the bearing planes of the roller conveyor mechanism 3 and the bearing platform 1. Moreover, the roller loading and unloading device is arranged at the lower position of the roller conveyor mechanism 3 and the bearing platform 1, and will not occupy additional space, making the entire roller conveyor system compact. Compared with other roller loading and unloading devices such as hanging mechanisms, fork delivery mechanisms, mechanical arms, etc., the structure is simpler, the material transfer distance is short, and the efficiency of loading and unloading can be improved and energy consumption can be reduced. In addition, the utility model can speed up the efficiency of loading and unloading materials on the roller conveyor. Specifically, when the roller conveyor mechanism 3 unloads materials, its conveying speed can be accelerated compared with the conventional roller conveyor mechanism 3. When the materials leave the roller conveyor mechanism 3, they slide frictionally with the carrying platform 1. The carrying platform 1 is equivalent to a buffer zone at this time, which can quickly reduce the moving speed of the materials 7 and avoid the problem of inertial sliding of the materials 7. When the roller conveyor mechanism 3 loads materials, the material transfer mechanism 2 drives the moving speed of the materials 7 to be faster than the conveying speed of the roller conveyor mechanism 3, thereby improving the loading efficiency.

[0038] In one of the embodiments, the carrying planes of the carrying platform 1 and the roller conveyor mechanism 3 are coplanar, so when the material 7 is switched between the carrying platform 1 and the roller conveyor mechanism 3, there is no height difference and the material 7 can be directly transferred from one carrying plane to another. There is no need to lift the material 7 and the material 7 will not tilt downward.

[0039] In one of the embodiments, the supporting platform 1 is made of graphite material. In this embodiment, the graphite material has self-lubricating properties and is wear-resistant, and can be well used for friction and sliding with the material 7.

[0040] In one of the embodiments, a limit baffle 14 is provided at one end of the carrying platform 1 away from the roller conveyor mechanism 3 , which can limit and position the material 7 entering the carrying platform 1 to prevent the material 7 from slipping off the carrying platform 1 .

[0041] In one embodiment, the first through groove 11 is a straight strip groove, and the first horizontal moving mechanism 22 is a linear driving mechanism, such as a cylinder, an oil cylinder or a linear electric cylinder. In a preferred embodiment, the first horizontal moving mechanism 22 is a linear module, which has the characteristics of precise control and strong load capacity; and the lifting mechanism 21 includes two cylinders arranged on both sides of the bottom of the linear module body, which can drive the linear module to lift and lower, and has a strong load capacity.

[0042] In one embodiment, the carrying platform 1 is arranged on the mobile bracket 4; the mobile bracket 4 can drive the carrying platform 1 to leave or approach the upstream / downstream end of the roller conveyor mechanism 3, so that when the roller conveyor mechanism 3 is unloaded, the material 7 unloaded from the roller conveyor mechanism 3 is conveniently transferred to the next station, and when the roller conveyor mechanism 3 is loaded, the material 7 at the previous station is conveniently transferred to the upstream end of the roller conveyor mechanism 3. Preferably, the mobile bracket 4 includes a fixed bracket and a mobile slide slidably arranged on the fixed bracket, and the carrying platform 1 is fixedly arranged on the mobile slide. Preferably, a third horizontal moving mechanism 41 for driving the mobile slide to slide is also arranged on the fixed bracket. Preferably, the third horizontal moving mechanism 41 adopts a cylinder, so as to facilitate the control of the accuracy of the docking between the carrying platform 1 and the roller conveyor mechanism 3.

[0043] In one embodiment, the roller conveyor mechanism 3 is fixedly disposed on the roller conveyor mechanism bracket 6 , and the lifting mechanism 21 is also fixedly disposed on the roller conveyor mechanism bracket 6 .

[0044] In one of the embodiments, the carrying platform 1 is arranged on the movable bracket 4 through a leveling and height-adjusting mechanism, thereby facilitating the leveling and height-adjusting of the carrying platform 1 to adapt to the carrying plane of the roller conveyor mechanism 3 .

[0045] In one embodiment, the carrying platform 1 is provided with a second through slot 13 intersecting with the first through slot 11;

[0046] The mobile bracket 4 is also provided with a loading and unloading mechanism 5 for loading and unloading the loading and unloading platform 1. Specifically, when the roller loading and unloading device is a roller loading device, the loading and unloading mechanism 5 for the loading and unloading platform 1 is used to load the loading and unloading platform 1, and when the roller loading and unloading device is a roller unloading device, the loading and unloading mechanism 5 for the loading and unloading platform 1 is used to unload the loading and unloading platform 1 to the next station. The loading and unloading mechanism 5 for the loading and unloading platform 5 includes a second horizontal moving mechanism 51 and a push-pull member 52 arranged on the output end of the second horizontal moving mechanism 51. Preferably, the second horizontal moving mechanism 51 adopts a linear module and is arranged on the mobile bracket 4 below the loading and unloading platform 1. A connecting rod is arranged between the push-pull member 52 and the sliding plate of the linear module. The connecting rod slides on the second through slot 13, and then the second horizontal moving mechanism 51 is used to drive the push-pull member 52 to move along the second through slot 13. Preferably, the first through slot 11 and the second through slot 13 are perpendicular to each other, that is, the adjacent two sides of the loading and unloading platform 1 are respectively used for loading and unloading.

[0047] In one embodiment, at least two groups of first through grooves 11 and material transfer mechanisms 2 are arranged along the width direction of the roller conveyor mechanism 3. When the material transfer mechanism 2 transfers the material 7, it can dock with the left and right sides of the material 7, thereby improving the stability during the transfer process.

[0048] The present invention also provides a roller conveyor system, comprising a roller conveyor mechanism 3 and the above-mentioned roller loading and unloading device;

[0049] Several rollers of the roller conveyor mechanism 3 near the roller loading and unloading device are equipped with one-way overrunning devices 31, that is, these rollers can overrun at a faster speed than the driving rotation speed, so that when the material 7 quickly enters or leaves the roller conveyor mechanism 3, no sliding friction will be generated with the rollers, thereby improving the service life of the rollers.

[0050] The above is only an embodiment and does not limit the present invention in any way. Any person skilled in the art can make many possible changes, modifications or modifications to the present invention without departing from the scope of the present invention by using the above disclosed technical contents. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the present invention should fall within the scope of protection of the present invention.
