Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to an intelligent silo device, in particular to an intelligent silo device used for loading and unloading materials on machine tools. Background Art

[0002] The loading and unloading device of a machine tool is a component of an automatic machine tool and an indispensable auxiliary device for an automatic production line. It is usually an automatic or semi-automatic mechanical device that delivers the workpiece to be processed to the processing position on the machine tool and removes the processed workpiece from the processing position. After the semi-automatic machine tool is equipped with a loading and unloading device, the processing cycle can be continuously and automatically carried out, becoming an automatic machine tool. The loading and unloading device of a machine tool is used for semi-automatic machine tools with high efficiency, short maneuvering time, and frequent loading and unloading of workpieces, which can significantly improve production efficiency and reduce physical labor.

[0003] The unloading mechanism of most machine tools is relatively simple. After the machine tool processes a workpiece, the unloading device will remove the processed workpiece and reload the workpiece to be processed. For the loading and unloading devices of single workpieces, there are generally two types: hopper type and silo type. Among them, the silo type loading device is mainly composed of a silo, a feed trough and a loading mechanism. The workpiece is manually arranged and loaded into the silo in advance, and then sent to the processing position on the machine tool through the loading mechanism.

[0004] In existing silo devices, in addition to manual loading, manual auxiliary loading mechanisms are often required to transport workpieces. The manual participation is high and the degree of automation is relatively low, which cannot achieve ideal automated processing. In addition, the number of workpieces processed each time is relatively small, and the work efficiency is low.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described below in conjunction with the embodiments and drawings.

[0030] like Figure 1 and Figure 2 As shown, the intelligent silo equipment includes:

[0031] A frame 10, on which a workbench 20 is arranged;

[0032] A material cart 50 is located below the workbench 20. A plurality of material trays 52 are stacked from bottom to top in the material cart 50. A plurality of workpieces (not shown in the figure) are arranged and distributed on each material tray 52.

[0033] The bracket 30 is arranged on one side of the workbench 20, and the bracket 30 can move up and down in the vertical direction and drive the material tray 52 to be transported back and forth between the material cart 50 and the workbench 20;

[0034] The robot (not shown in the figure) is located on one side of the frame 10. The robot can move back and forth in the horizontal direction. When the robot is close to the workbench 20, it can grab the workpiece on the tray 52 and further transport the workpiece to the processing equipment (not shown in the figure).

[0035] In existing silo devices, in addition to manual loading, manual auxiliary loading mechanisms are often required to transport workpieces. The manual participation is high and the degree of automation is relatively low, which cannot achieve ideal automated processing. In addition, the number of workpieces processed each time is relatively small, and the work efficiency is low.

[0036] To this end, the present invention designs an intelligent silo device, which realizes the automatic transportation of the material tray 52 through the coordinated arrangement of the bracket 30, the material cart 50 and the workbench 20, avoids frequent manual feeding, has a high degree of automation, and is convenient for wide use.

[0037] Specifically, the frame 10 is provided with two spaces, one side of which is used for the bracket 30 to move up and down, and the other side is provided with the workbench 20, and the material cart 50 is sent from the outside to the bottom of the workbench 20. During operation, the material tray 52 on the material cart 50 moves to the bracket 30 and moves to the workbench 20 after the bracket 30 moves up, so that the manipulator can grab the corresponding workpiece and send it to the processing center or other equipment for processing, and the specific processing equipment is not limited here.

[0038] like Figure 2 and Figure 3 As shown, in this embodiment, two vertical slide rails 11 are preferably symmetrically installed on both sides of the frame 10, and the bracket 30 drives the material tray 52 to move up and down along the two vertical slide rails 11.

[0039] The bracket 30 actually moves up and down along the two vertical slide rails 11. The bracket 30 can drive the material tray 52 to move up to the workbench 20 to wait for the workpieces to be processed in sequence, or it can move the material tray 52 carrying the processed workpieces down and send it back to the material cart 50. When all the workpieces on the material cart 50 are processed, the material cart 50 exits the frame 10.

[0040] Preferably, two feeding layers 33 for supporting the material tray 52 are arranged in the upper and lower parts of the bracket 30 , two first guide plates 31 are fixedly provided on each feeding layer 33 , and a plurality of rollers 521 corresponding to the two first guide plates 31 are installed at the bottom of the material tray 52 .

[0041] In this embodiment, two feeding layers 33 are preferably provided on the bracket 30 to facilitate the conveyance of the material tray 52 to be processed and the processed material tray 52 , and the conveyance is completed at one time, thereby avoiding frequent movement of the bracket 30 .

[0042] The provision of the first guide plate 31 here, on the one hand, facilitates the stable placement of the roller 521 on the material tray 52, and on the other hand, facilitates the material tray 52 to move in the horizontal direction under the action of the roller 521, and the use effect is good.

[0043] Furthermore, a feeding cylinder 32 is installed on the feeding layer 33 and the feeding cylinder 32 is located between the corresponding two first guide plates 31. A push plate 321 is fixedly connected to the output shaft of the feeding cylinder 32. A slot 522 for the push plate 321 to be embedded is provided at one end of the material tray 52 away from the cylinder. The feeding cylinder 32 drives the push plate 321 to drive the material tray 52 to enter or leave the feeding layer 33.

[0044] It is worth mentioning that the material tray 52 is actually driven by the feeding cylinder 32 installed on the feeding layer 33. Specifically, when the material tray 52 is located on the material cart 50, the bracket 30 moves down to the position of the material cart 50, and the feeding cylinder 32 causes the push plate 321 to move toward the material tray 52 until it reaches the slot 522. At this time, the bracket 30 drives the feeding cylinder 32 to move up a certain distance (the specific distance depends on the actual situation), so that the push plate 321 is embedded in the corresponding slot 522, and then the feeding cylinder 32 drives the output shaft to move in the opposite direction, thereby driving the material tray 52 to move to the feeding layer 33 of the bracket 30. When the bracket 30 moves to the position of the workbench 20 with the material tray 52, the feeding cylinder 32 drives the push plate 321 to push the material tray 52 to move to the workbench 20.

[0045] Here, it is preferred that the first guide plates 31 on the two feeding layers 33 are actually formed by bending and extending the upper and lower ends of the two side walls of the bracket 30 respectively, and a plurality of support plates are fixed between the two first guide plates 31 of each layer, and the above-mentioned feeding cylinders 32 are installed on the corresponding support plates. Of course, in actual manufacturing, an obvious hierarchical structure can be set on the bracket 30, which is not limited in this embodiment.

[0046] Preferably, two locking cylinders 21 are fixed on the workbench 20, and two second guide plates 22 corresponding to the two first guide plates 31 are installed between the two locking cylinders 21. When the material tray 52 moves along the first guide plate 31 to the second guide plate 22, the two locking cylinders 21 clamp the material tray 52.

[0047] In this embodiment, a second guide plate 22 corresponding to the first guide plate 31 is preferably installed on the workbench 20. Through the cooperation between the first guide plate 31 and the second guide plate 22, the material tray 52 can move back and forth between the bracket 30 and the workbench 20 stably.

[0048] The two locking cylinders 21 clamp the material tray 52, which can further ensure that the material tray 52 is stably installed on the workbench 20, making it easier for the robot to grab the workpiece.

[0049] like Figure 4 and Figure 5 As shown, further, a plurality of notches 523 for the push plate 321 to pass through are provided on the material tray 52 , and a clamping plate 53 located in the clamping groove 522 is movably installed at the bottom of the material tray 52 .

[0050] Furthermore, the material cart 50 is provided with a plurality of material storage layers 51 , each material storage layer 51 is mounted with two third guide plates 54 corresponding to the two first guide plates 31 , and each third guide plate 54 is provided with an opening 541 corresponding to the clamping plate 53 .

[0051] The notch 523 on the tray 52 facilitates the output shaft of the feeding cylinder 32 to move below the tray 52, and facilitates the push plate 321 to penetrate the tray 52 and then be embedded in the corresponding slot 522, thereby driving the tray 52 to move.

[0052] In this embodiment, it is preferred that a plurality of material storage layers 51 are provided in the material storage layer 51 , and a third guide plate 54 is installed in the material storage layer 51 to facilitate the material tray 52 to be sent out or to enter the material storage layer 50 again.

[0053] In order to ensure that the material tray 52 remains in a stable state on the material cart 50, it is preferably here that a card plate 53 is movably installed in the card slot 522 of the material tray 52, and an opening 541 corresponding to the card plate 53 is opened on the third guide plate 54. When the material tray 52 is located on the material cart 50, the card plate 53 is embedded in the opening 541, thereby limiting the movement of the material tray 52; when the push plate 321 on the feeding cylinder 32 is embedded in the card slot 522, the bracket 30 moves up and drives the card plate 53 to move up and out of the opening 541, thereby allowing the material tray 52 to break away from the restriction on the material cart 50, thereby facilitating the movement of the material tray 52.

[0054] In addition, there are gaps between the end surface of the first guide plate 31 facing the second guide plate 22 and the end surface of the second guide plate 22 and the end surface of the third guide plate 54. The setting of the gap avoids interference with other component brackets when the bracket 30 moves in the vertical direction, ensures smooth movement of the bracket 30, and is conducive to the progress of related work.

[0055] When the material tray 52 moves, it is always between the first guide plate 31 and the corresponding second guide plate 22 or third guide plate 54 . It is necessary to ensure that the upper surfaces of the corresponding guide plates are in the same horizontal plane to facilitate smooth movement of the material tray 52 .

[0056] Preferably, each tray 52 is covered with a chuck 55 for embedding workpieces, and a plurality of evenly distributed clamping positions 551 are provided on the chuck 55. In this embodiment, the manipulator can move in the horizontal direction and the vertical direction. Therefore, the workpieces on the tray 52 are arranged in a matrix, which is convenient for the manipulator to pick up and place the workpieces. The actual working condition depends on the movement condition of the manipulator.

[0057] like Figure 3 As shown, further, two horizontal slide rails 12 are horizontally arranged in the frame 10, and the above-mentioned workbench 20 is arranged across the two horizontal slide rails 12, a driving motor 41 is installed between the two horizontal slide rails 12, the output shaft of the motor is connected to a gear 61, and a rack 62 meshing with the gear 61 is installed at the bottom of the workbench 20.

[0058] Here, the manipulator can actually only move in one direction in the horizontal direction. When the manipulator takes any workpiece on the material tray 52, it needs to be assisted by changing the position of the material tray 52. ​​Preferably, the workbench 20 is installed on the frame 10 through two horizontal slide rails 12, so that the workbench 20 can drive the material tray 52 to move back and forth in the horizontal direction, which is convenient for the manipulator to take and place any workpiece. At the same time, gears 61 and racks 62 that cooperate with each other are provided, and the movement of the workbench 20 is controlled by the drive motor 41 to ensure that the workbench 20 is stable, controllable, and easy to use.

[0059] Preferably, a transmission shaft 43 is arranged across the top of the frame 10, and a stepper motor 42 is connected to the transmission shaft 43, first sprockets 71 are respectively provided at both ends of the transmission shaft 43, and two second sprockets 72 corresponding to the two first sprockets 71 are symmetrically arranged at the bottom of the frame 10, each first sprocket 71 is connected to the corresponding second sprocket 72 through a conveying chain 80, and the above-mentioned bracket 30 is located between the two conveying chains 80 and the bracket 30 is respectively fixed to the two conveying chains 80.

[0060] In this embodiment, it is preferred that a sprocket cooperates with a conveying chain 80 to drive the bracket 30 to move up and down, and the stepping motor 42 further controls the rotation of the two conveying chains 80 to ensure stable and accurate movement of the bracket 30.

[0061] The driving motor 41 and the stepping motor 42 are connected to the corresponding components through corresponding reducers to ensure that the power output of the motor is more stably transmitted to the corresponding components and the working effect is better. In actual operation, the two motors are driven by a control system (not shown in the figure) in the frame 10 to ensure stable and reliable operation.

[0062] Furthermore, two tensioning wheels 73 corresponding to the two conveyor chains 80 are installed in the frame 10. The setting of the tensioning wheel 73 can tension the conveyor chain 80 to prevent the conveyor chain 80 from being too loose or too tight, and automatically adjust the tension to make the entire transmission system more stable, safe and reliable.

[0063] It is worth mentioning that in this embodiment, the lower feeding layer 33 of the two feeding layers 33 preferably always transports the material tray 52 to be processed from the material cart 50 to the workbench 20, and the upper feeding layer 33 always returns the processed material tray 52 on the workbench 20 to the material cart 50. This arrangement facilitates the removal of the material tray 52 at the lower position in the material cart 50.

[0064] During actual operation, the feeding layer 33 located below the bracket 30 takes out the material tray 52 from the material cart 50, and then transports it to the workbench 20 to wait for processing. At this time, the bracket 30 takes out the next material tray 52 from the material cart 50 again. When the previous material tray 52 is processed, the bracket 30 moves to the workbench 20, takes out the previous material tray 52 to the upper feeding layer 33. At this time, the bracket 30 further moves up a certain height, delivers the next material tray 52 to the workbench 20, and then moves down to the material cart 50, sends the previous material tray 52 back to the material cart 50, and takes out a new material tray 52 to be processed. This cycle is repeated until the material tray 52 on the material cart 50 is processed. At this time, the material cart 50 is replaced to carry out the next round of processing.

[0065] like Figure 1 As shown, in this embodiment, a plurality of visual windows 13 are preferably provided around the frame 10, and the visual windows 13 are arranged close to the workbench 20 to facilitate observation of the actual feeding situation, and the visual windows 13 on one side are arranged to penetrate upward to facilitate the robot arm to enter the frame 10 to grab the workpiece on the workbench 20 (material tray 52).

[0066] An opening and closing door 90 is also installed on the frame 10. When the material cart 50 enters the frame 10, the opening and closing door 90 is closed. In this embodiment, the material cart 50 is preferably in a fastened state after the opening and closing door 90 is closed to avoid the material cart 50 from moving due to external force when the feeding cylinder 32 takes the material tray 52. ​​It ensures that the material cart 50 is in a stable state, which facilitates the material tray 52 to smoothly enter and exit the material cart 50, which is conducive to the smooth progress of the feeding work.

[0067] The intelligent silo equipment has a reasonable structure. The bracket 30, the material cart 50 and the workbench 20 are used to coordinate and realize the automatic transportation of the material tray 52. ​​At the same time, the bracket 30 can realize multiple back and forth transportation of the material tray 52, which is convenient for processing and storage of workpieces on the material tray 52 and avoids frequent manual feeding. It has a high degree of automation and is convenient for wide use.

[0068] The preferred embodiments of the present invention are described herein, but the protection scope of the present invention is not limited thereto.
